I. Introduction Since the 1970's drug abuse among young people has increasingly become a social problem in Korea. In the 1980's, drug abuse, especially glue sniffing, has become the cause of many unfortunated incidents resulting in harm to others as well as the abusers themselves. Taking into consideration of the seriousness of this problem, the Republic of Korea National Red Cross initiated a nation-wide research programme, to understand the present situation and to raise the level of public awareness. The goal of this research was to begin a nation - wide campaign against drug abuse. The research team was composed of the Advisary Committee members and the staff of the Youth Department of the Republic of Korea National Red Cross. The data were collected in February 1988 with the collaboration of the staff and volunteers in the local Chapters. The respondents were allocated nation-wide by the quota sampling method. The questionnaires were distributed to the respondents in three groups :2, 700 to junior and senior high school students, 605 to working youths, and 916 to delinquent youths. A total of 4, 221 questionnaires were collected. II. Characteristics of the Respondents The respondents in each group were selected evenly from rural and urban areas. The general characteristics of the respondents can be described as follow: in case of students, the proportions between male and female respondents, and between senior high school and junior high school students were almost evenly distributed. In case of working youths, the proportion of females (80.5%) was higher than those of the students and the delinquents groups. Delinquent youths were defined as those currently being under custody of the centers for juvenile delinquents. Of this number, 38.8% and 68.2% were junior and senior high school drop-outs respectively. The majority of them (92.6%) were male. As for the family background of the respondents, the proportion of those residing in poverty - stricken areas, and the proportion of those from broken families were higher in case of working youths and delinquent youths than those in case of students. III. Present Patterns of Drug Abuse The following summarizes the presents of drug abuse, as tabulated from the results of the survey. 1. Smoking The percentage of youths who smoke was 36% in the student group, 32% m the working youths group, and 94.4% in the delinquent youths group. 2. Alcohol 50.3% of students, 71.6% of working youths, and 93.3% of delinquent youths has experienced drinking alcohol beverages. 3. Tonic: non - alcoholic, caffeinated beverages popular in Korea and Japan The percentage of those who have used tonic at least once was over 90% in all of the three groups. 4. Sedative About 70% of each group has used sedative with the proportion of working youths use higher than those in other groups. 5. Stimulants Those who have used stimulants comprised around 15% in each group. 6. Tranquilizers Somewhat less than 5% of students and working youths, and 28% of delinquent youths, have used tranquilizers. 7. Hypnotics The users of hypnotics amounted to 0.4% of students, 2.6% of working youths and 7.1% of delinquent youths. 8. Marihuana Those who have used marihuana indicated 0.7% of students, 0.8% of working youths, and 13% of delinquent youths. 9. Glue-sniffing The percentage of glue-sniffing was 3.7%, 5% in the students group and in the youths group respectively, but the proportion was unusually high, at 40.7% in the delinquent youths group. From the results of the survey the present situation of drug abuse in Korea can be summarized as follows: 1. A high percentage of Korean youths have experienced smoking cigarettes and drinking alcoholic beverages. 2. Tonics (non - alcoholic, caffeinated beverages), antipyretic analgesics and stimulants quite regularly used. 3. Tranquilizers, hypnotics, marihuana and glue-sniffing are more widely used among delinquent youths than the other youths. From this fact, there exists a correlation between drug abuse and juvenile delinquency. IV. Time-series Analysis of the First Experience of Drug Abuse and Deviant Behaviour The respoundents were asked when they were first exposed to drugs and when they committed deviant acts. By calculating the average age of each experience, the following pattern was found (See Figure 1). Youths are first exposed to drugs by abuse of tonic(non - alcoholic, caffeinated beverages). At the age of 13, they amoke cigarettes, the use of antipyretic analgesics begins at 14 year old, while at the age of 15, they use tranquilizers, and at 16 hynotics. The period of drug abuse which starts from drinking caffeinated beverages and smoking cigarettes and ends in the use of hypnotics takes about three years. During this period, other delinquent behaviours begin to surface, that is, at the age of 13 when smoking cigarettes begins, the delinquent behaviour pattern starts with truancy. Next, they start taking money from others by using physical force. Prior to the age of 15, they are suspended from school, become hostile to adults, begin running away from home, and start using stimulants and alcohol. Soon they become involved even in glue-sniffing and in the use of marihuana. At the age of 15, they begin to see adult videos and carry weapons. Sexual promiscuity and usage of tranquilizers follows the viewing of adult videos. Consequently, by the time they reach the age of 16, they visit drinking establishments, and are picked up by police for committing delinquent acts. And finally, they come to use hypnotic - type drugs. From the above descriptions, drug abuse can be assumed to have a close correlation with delinquent behaviour. V. Social Factors Related to Drug Abuse As for the Korean youths, glue-sniffing is found to he related to aggressive delinquency, in such cases as run - aways, being picked up by the police, and taking money by force. Smoking cigarettes and drinking alcohol is found to be related to seeing adult videos and visiting drinking establishments. Hypnotics and marihuana were found to be representive of drugs which are related to degenerational delinquency, irrespective of social delinquency. The social factors connected with these drug abuse are as follows: 1. Individual factors Male students were more heavily involved in the usage of drug than females. Youths who do not attend church were more likely to be involved in drugs than those who attend. 2. Family factors The youths who were displeased with their mothers smoking and those who thought their parents did not love each other, or those whose parents had used drugs without prescription, were more likely to he drug users. 3. School factors Those youths who found school life boring, were unsuccessful in their studies, spend most of their time with friends, feel their teachers smoke too much, those who had a positive perception of their teachers smoking were likely to he drug users. To sum up, drug abusers depend on the influence of their parents, teachers and peers. IV. Reasons for Drug Abuse Korean students have mainly used drugs to release stress (42.8%), to stay awake (19.7%), and because of the easy accessibility of drugs( 16.6%). Other reasons are due to their ignorance of the side effects of the drugs (3.6%), natural curiosity (4.2%), and to increase strength(3.O%). From the above facts, the major reasons for drug abuse among Korean youths are to release stress and to stay awake in order to prepare exams. Furthermore, since drugs are readily available, we can conclude that drug abuse is caused by the school system(such as entrance exams) in Korea. VII. Conclusion Drug usage among Korean youths are relatively less common than those of western youths. In some cases, such as, glue-sniffing and use of stimulants, the pattern of drug abuse is found. Moreover, early drug abuse is evident, and it has a close connection with deviant behaviour, resulting in juvenile delinquency. Drug abuse cannot be attributed to any one social factor. Specifically, drug abuse depends on parents, peers, teachers and other members of the community, and also is influenced by social institutions such as the entrance exam system. Every person and organization concerned with youth must participate collectively in restraining drug abuse. Finally, it is suggested that social agencial working for youth welfare should make every effort to tackle this serious problem confronted by the Korean youths today.

Rubella is a viral disease with mild constitutional symptoms and generalized rashes. In childhood, it is an inconsequential illness, but when it occurs during early pregnant period, there are significant risks of heart defects, cataract, mental retardation to the fetus. The series of congenital defects induced by rubella is called 'congenital rubella syndrome'. Many research have been performed to find out more effective prevention program on rubella. The objectives of this study are, first, to calculate the incidence rate of acute rubella infection and congenital rubella syndrome in Korea, second, to evaluate economic efficiency of several rubella vaccination policies and to offer data for the most reasonable decision on vaccination policy. Study populations are 663,312 children of one year-old in 1992. The author has performed cost-benefit analyses according to the three vaccination policies-U.S.A.'s. U.K.'s and Sweden's. In this Study, the author got the incidence rate of acute rubella infection using the catalytic model. In the meantime, the author used 50 per 100,000 live births as the incidence rate of congenital rubella syndrome. The discount rate used in this study was 5 percent per annum. The sensitivity analyses were done with different discount rates (4%, 7%) and different incidence rate of congenital rubella syndrome (10,100 per 100,000 live births) : The study results are as follows: 1. Without vaccination, lifetime expenditures per patient for acute rubella infeciton amount to 14,822 won and the total expenditures to about 3.1 billion won. Meanwhile, lifetime expenditures per patient for congenital rubella syndrome amount to about 91 million won and the total expenditures to about 16.3 billion won without vaccination. 2. The cost of vaccination for a child of one year old was 2,322 won and the total cost for the one year old children was about 1.5 billion won (American style). The cost for vaccination of female children at fifteen was about 339 million won (Birtish style). And the cost of vaccination at one for both sex and female children at fifteen was about 1.9 billion won (Swedish style). 3. The benefit to cost ratios of vaccination of female children at fifteen that is the british mode of rubella vaccination, was 60.0 at the level of 80% population coverage and 48.6 at 100% coverage. It shows much higher benefit to cost ratio than those of the other two vaccination policies. 4. Both net benefits of vaccination at one (American style) and that of vaccinations at one and fifteen (Swedish style) range from about 17.0 billion to 17.8 billion won, those were larger than that of vaccinations of female children at fifteen (Birtish style, about 16.0 billion). 5. In marginal cost-benefit analysis of only additional program of revaccination, the benefit to cost ratios were 3.6 (80% coverage rate) or 0.6 (100% coverage rate). It implies that additional program was less efficient or inefficient. 6. In sensitivity analysis with different discount rates(4% or 7%) and different incidence rates of congenital rubella syndrome (10 or 100 per 100,000 live births), the benefit to cost ratios has fluctuated in wide range. However, all the ratios of vaccination of female children at fifteen were higher than those of the others. Even under the most conservative assumption, the benefit to cost ratios of all the rubella vaccination policies were higher than 3.3. In conclusion, all the rubella vaccination policies found to be cost-effective and particularly the vaccination of female children at fifteen was strongly recommended.

단체급식에서 적용할 수 있는 HACCP 시스템 개발시 필요한 기초자료를 얻고자 현재 급식소에서 가열처리 없이 급식되어 위생관리가 요구되는 생채류 조리의 위생실태를 파악하고 생채류 조리의 전처리 단계에서의 채소류에 대한 식초소독의 효과를 실험하였다 고등학교 급식소 5개소의 2002년 1월부터 5월까지의 식단을 분석하여 급식횟수가 높은 생채류 중, 부추겉절이, 도라지생채, 야채샐러드의 미생물적 품질을 평가한 결과, 부추겉절이와 도라지 생채는 1g당 총균수는 $10^{5}$ ~$10^{6}$ CFU, 대장균군은 $10^2$~$10^4$CFU 수준으로 위생관리가 요구되는 상태였다. 급식소에서 생채류의 재료가 되는 부추를 물로 3회 세척한 후, 총산 농도 0.05%, 0.1%, 0.5%, 1%, 2%로 조절하고 농도별로 온도를 1$0^{\circ}C$, 2$0^{\circ}C$, 4$0^{\circ}C$로 유지시킨 식초소독액 각각에 부추를 넣어 5분, 10분, 30분 동안 침지시킨 효과를 실험하였다. 식초 농도가 증가할수록 부추의 총균수와 대장균군수의 감소가 증가하였으며 같은 농도에서 소독액의 온도가 높을수록, 침지시간이 길어질수록 그 효과는 높았다. 본 연구 결과에 기초하여 채소류의 질감 손상과 에너지 비용면을 고려할 때 채소류의 초기 총균수가 $10^{6}$대장균군수는 $10^3$수준일 경우 0.5%, 2$0^{\circ}C$의 식초용액으로 10분간 소독하는 것 이 적절할 것으로 생각되었다. 전처리전부추 원시료, 3회 세척한 부추, 3회 세척 후 2$0^{\circ}C$의 0.1%, 0.5%, 1% 식초소독액에서 10분간 침지시킨 부추각각의 시료들을 4$^{\circ}C$에서 저장하면서 시간별로 총균수와 대장균군수를 검사하였다. 부추 원시료와 3회 세척 시료는 저장시간이 길어질수록 미생물은 증가하여 72시간의 저장으로 저장전에 비해 총균수는 각각 5.41 log(1.8배), 0.75 log(5.6배 ), 대장균수는 각각 0.30 log(2배 ), 0.24 log(1.8배) CFU/g증가하였다. 반면 0.1%의 식초소독액에 침지하였던 부추시료들은 72시간의 저장으로 총균수와 대장균군수가 다소 증가하였으나 0.5%와 1%의 식초소독액에 침지하였던 부추시료들은 저장시간이 길어질수록 총균수와 대장균군수가 오히려 감소하였는데 이는 식초 침지시 손상되었던 부추의 총균과 대장균군의 증식이 억제된 때문이라 사료된다. 식중독 병원균인 staphy-lococcus aureus, EscheriEcia coli O157, Shigelia sonnei, Salmonella entritidis, Listeria monolytogenes를 식초농도별로 1$0^{\circ}C$에서 10분간 처리하여 배양시킨 결과, 식초농도 1%이상에서는 검출되지 않았다.

목 적: 림프절 전이가 동반된 직장암 환자들에서 cyclooxygenase-2 (COX-2) 발현이 생존율에 미치는 영향을 조사 하고자 한다. 대상 및 방법: 1998년부터 2004년까지 직장암으로 동아대병원에서 근치적 수술과 수술 후 방사선치료를 받은 환자들 중에서 림프절 전이가 동반된 경우를 대상으로 후향적분석을 하였다. 86명 중에서 수술 후 조직을 찾을 수 없는 3명, 악성 흑색종 1명, 진단 전후 2년 내에 위암과 폐암이 발생한 각 1명, 진단 시에 간 전이가 있었던 1명, 720 cGy 후 방사선치료를 거부한 1명 등을 제외한 78명을 대상으로 분석하였다. COX-2에 대한 면역조직화학염색은 자동면역염색기로 하였고, 스캔한 후, 영상분석기를 이용하여 분석하였다. Kaplan-Meier 생존율 분석을 하였고, Log rank 검사로 유의성을 조사하였다. 결 과: 면역조직화학염색에서 COX-2 양성이 62명(79.5%), 음성이 16명(20.5%)이었고, 양성도가 1, 2, 3인 환자들이 각각 6명(7.7%), 15명(19.2%), 41명(52.6%)이었다. 환자의 나이(60세 미만, 이상), 성별, 수술 방법(복회음절제술, 하위전방절제술), 세포의 분화도, 종양의 크기(5 cm 미만, 5 cm 이상), T병기, N병기, 병기(IIIa, IIIb, IIIc), 등에 따른 COX-2 발현의 차이는 없었다. 전체 환자의 5년 생존율과 무병생존율은 각각 57.0%, 51.6%였다. COX-2 음성과 양성인 환자들의 5년 생존율이 72.9%와 53.0% (p=0.146), 5년 무병생존율이 72.7%와 46.3% (p=0.118)였다. COX-2 양성도가 0, 1, 2, 3인 환자들의 5년 생존율은 각각 72.9, 50.0 51.3, 53.1%였고(p=0.495), 5년 무병생존율은 각각 72.7, 50.0, 46.7, 45.1%였다(p=0.451). 5년 생존율은 악성종양 세포의 분화도, N병기, 병기, 등에 따라서, 5년 무병생존율은 N병기, 병기, 등에 따라서 유의한 차이가 있었다(p<0.05). 결 론: 림프절 전이가 동반된 직장암 환자에서 COX-2의 발현 여부와 정도는 생존율에 유의한 영향을 주지는 않았다. 하지만 향후 보다 많은 환자군을 대상으로 연구하여, COX-2 발현이 직장암의 예후에 미치는 영향을 규명해야 할 것으로 생각된다.

목적 : 초, 중, 고등학생들을 대상으로 실시한 집단뇨 검사의 전반적인 분석에 대한 연구 결과들은 여러 연구자들에 의해 지속적으로 보고되었으나, 단독 단백뇨(isolated proteinuria)에 대한 연구는 소수에 불과하다. 국내에서는 매년 전체학생의 0.3-0.5% 정도를 차지하는 것으로 보고되어 있다. 단백뇨는 과도한 양의 단백이 소변으로 배출되는 것으로, 증상이 없는 환자에서 발견된 단백뇨는 심각한 신장질환이나 전신 질환의 초기 발현이거나 혹은 임상적으로 의미 없는 일시적인 소견일 수 있다. 그러나 지속적인 단백뇨의 경우는 향후 진행성 신질환의 경과를 취하는 경우가 적지 않으므로 진단 당시 정확한 검사 및 지속적인 외래 추적 관찰이 필수적이다. 이에 저자들은 부산 경남지방에 거주하는 초, 중, 고등학교 학생들 중학교 신체검사에서 우연히 발견된 단독 단백뇨를 주소로 본 원을 방문하였던 학생들을 대상으로, 단독 단백뇨의 원인을 규명하고, 전국적인 자료 구축의 기본적인 데이터를 제공하고자 본 연구를 시행하였다. 방법 : 2002년 4월부터 2003년 8월까지 학교 신체 검사에서 발견된 소변 검사상의 이상 소견을 주소로 부산백병원 소아과를 방문하였던 학생 중 단독 단백뇨의 소견을 보였던 초, 중, 고등학생 44명을 대상으로 전향적으로 조사하였다. 성별은 남자가 15명, 여자가 29명으로 남녀 비는 1:1.93이었다. 연령은 7세부터 16.9세까지로 평균 연령은 12.0세였다. 모든 학생들은 소아신장학회의 프로토콜에 의거하여 검사를 시행하였다. 결과 : 단독 단백뇨를 보였던 44명 학생들에서 단백뇨의 원인적 분석 결과는 일시적 단백뇨가 4례(9.1%), 기립성 단백뇨가 36례(81.8%), 지속성 단백뇨가 4례(9.1%)로, 기립성 단백뇨가 가장 많았다. 본원에 의뢰된 학생들의 학교 신체검사상에서의 단백뇨 정성검사(urine dipstick test) 결과를 보면, 전체적으로 2+가 24례(54.5%)로 가장 많았으며, Trace와 3+가 각각 6례, 1+ 5례, 4+ 3례였다. 기립성 단백뇨 군에서는 2+가 21례(58.3%)로 가장 많았다. 24시간 채집뇨상의 총단백량은 일시적 단백뇨 군에서는 평균 $121.0{\pm}136.4\;mg$이었고, 기립성 단백뇨 군은 평균 $179.1{\pm}130.0\;mg$, 지속성 단백뇨 군은 $1,532.8{\pm}982.5\;mg$이었다. 기립성 단백뇨 군에서는 24시간 채집뇨상의 총단백량의 범위가 40 mg에서 616 mg까지로 비교적 넓은 범위를 나타내었다. 단회뇨를 이용하여 측정한 PCR은 일시적 단백뇨군에서는 평균 $0.10{\pm}0.01$이었고, 기립성 단백뇨군은 평균 $0.61{\pm}0.61$, 지속성 단백뇨 군은 평균 $4.35{\pm}4.04$이었다. 기립성 단백뇨 군에서는 PCR의 범위가 0.09에서 2.32까지의 편차를 나타내었다. 지속성 단백뇨를 보이는 경우가 4례에서 관찰되었다. 이들 모두는 1년 동안 계속하여 단백뇨가 나타났으며, 결국 신조직 검사를 시행하였다. 1례는 미세병변이었고, 나머지 2례는 막증식성 사구체 신염이였으며, 나머지 1례는 신유전분증이었다. 결론 : 단백뇨의 검출은 신장질환의 존재를 확인해 줄 뿐만이 아니라 지속적인 단백뇨는 진행성 경과의 위험성을 동시에 암시해 주는 매우 유용한 지표이다. 본 연구 결과 학교 신체 검사상에서 발견된 단독 단백뇨의 주된 원인은 기립성 단백뇨로 81.8%를 차지하였다. 그러나 지속성 단백뇨의 경우 비록 9.1%의 빈도를 보였지만, 신장 조직검사를 시행한 결과 진행성 경과를 취할 수 있는 막 증식성 사구체 신염과 매우 희귀한 증례인 신유전분증 등으로 진단됨으로써 지속성 단백뇨의 경우 정확 진단적 접근이 필수적임을 알 수 있다. 기립성 단백뇨의 경우는 간단한 소변 검사만으로도 진단이 가능하므로 필요하지 않은 검사의 무분별한 시행이나 신장 질환에 대한 막연한 불안감을 해소할 수 있다. 초, 중, 고등학생을 대상으로 시행하고 있는 집단 소변 검사는 예방적인 차원에서의 의료 관리의 전형적인 사례로 볼 수 있다. 이의 성공적이면서도 확고한 정착을 위해서는 각 지역을 중심으로 시행되어진 자료의 수집과 관리를 일원화하는 작업이 요구되고 있다. 이를 통해 얻어진 자료들의 통계적 분석과 다양한 예시들은 소아 신질환의 관리의 귀중한 이정표를 제시해 줄 것이다.

It is widely recognized that primary health care in the community is one of the most important and effective health measures in these days. However, it is reality that unsatisfactory health care system, ineffective utilization of health care by the community people in the rural area are hampering better understanding for primary health care. Therefore promoting health for the rural people and increasing understanding about primary health care, the baseline survey in the community focused in examination for safe community water supply was carried out. The survey was conducted through August 25-31, 1986 in order to find out health problems and relevant factors and to define the demographic characteristics of $^*$Sanpuk village, Kumsa-Myun, Yuju-Gun, Kyunggi-Do, Korea. Household survey was carried out for every home by trained interviewers. The major results are found out as follows : 1) 84.2%(400 houses) of total households were surveyed because 15.8%(75 houses) were unable to survey due to either refusal against interview or absence of family. These 400 households were composed of 1,697 residents(male:830, female 867). Educational level of respondents showed 34.1% as elementary school graduated. Religion distribution showed Buddism(23.8%) as the most dominant. 50.7% of respondents married in the area. 2) Most households(91.5%) have lived in their own house in Sanpuk area. Average family size showed 4.3. More than half of residents(64.2%) have used public supplied water tap. Only 1.5% of the households had a flush toliet. The rest of households have still used primitive insanitary latrines. 3) 32.5% of residents have used gas burner for cooking and for heating in the house, and the coal briquet were used for boiler. Lack of convenient public transportation was the chief complaint for their day life. 4) Each household occupied 1,990 pyungs of rice paddy and 1,170 pyungs of ordinary field in average. Beside farming products, mushroom was the highest product. 5) Sixth percent of households in the survey area regularly participated in community meeting one hand and on the other hand 39.5% never participated. Most of respondents closely contacted with their neighbours and they seemed very friendly each other. 6) The prevalence rate of illness and injury during recent 15 days showed 48.3 per 1,000. The prevalence rate of chronic illnesses during the past one year showed 74 per 1,000. Injury and accident lead the higher portion(22.0%) in the former and in the latter pain(arthritis, back-pain) showed 27.0% as the dominant sickness. 87.8% of the ill residents in the former received medical treatment. As the most frequently utilized medical facility, the clinic or hospital were counted. Among the residents suffering from chronic illnesses, 77.3% in Sanpuk area get some kind of medical treatments and they rarely utilized the clinic or hospital. The reason why the patient did not receive any medical care was found out the fact that symptoms of illness was light or mild and economic problems was serious. 7) Average age of marriage showed 21.6 years old in the women and the average duration of marital period was shown for 15.1 years. The married woman in reproductive age in Sanpuk area had experienced pregnancies 4 times in the aver-age including 0.7 time of pregnancy in average were interrupted by induced abortion and 0.3 time by spontaneous abortion respectively. The practicing rate of the family planning of the married woman during reproductive ages showed 70.7% and the tuballigation was found out as the most frequently used contraceptives. 8) Among woman who has children under 2 years old, 70.0% had received the prenatal care for the last pregnancy. However, the average number of prenatal care visitis per woman showed 3.3 times. Fifty-two % of woman who received the postnatal care for the last delivery showed only 37.5%. 9) Immunization rate of the children under 2 years old showed relatively high and looked successful. The breast feeding for these children showed dominantly in the most. Most of the mothers in Sanpuk area had started the supplementary diet during weaning period of their infants of 6th and 7th month after birth. * : Sanpuk area is a demstration area for community development which has been supported by the Community Development Foundation during the part 10 years. The village is relatively closer to urban area such as Seoul, However, it has a similar characteristics shown as a remote village because of geographical location and inconvenient transportation at present.

Background: Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide and it is responsible for most cases of cervical uterine cancer. Although HPV infections of the cervix do not always progress to cancer, 90% of cervical cancer cases have been found to be associated with high risk HPV (HR-HPV) infection. HPV DNA testing is widely used, along with Papanicolaou (Pap) testing, to screen for cervical abnormalities. However, there are no data on the prevalence of genotype-specific HPV infections assessed by measuring HPV E6/E7 mRNA in women representative of the Chinese population across a broad age range. Materials and Methods: In the present study, we compared the results with the CervicGen HPV RT-qDx assay, which detects 16 HR-HPV genotypes (Alpha-9: HPV 16, 31, 33, 35, 52, and 58; Alpha-7: HPV 18, 39, 45, 51, 59, and 68; and Alpha-5, 6: HPV 53, 56, 66, and 69), and the REBA HPV-ID assay, which detects 32 HPV genotypes based on the reverse blot hybridization assay (REBA) for the detection of oncogenic HPV infection according to cytological diagnosis. We also investigated the prevalence and genotype distribution of HPV infection with a total of 324 liquid-based cytology samples collected in western Shandong province, East China. Results: The overall HPV prevalences determined by HPV DNA and HPV E6/E7 mRNA assays in this study were 79.9% (259/324) and 55.6% (180/324), respectively. Although the positivity of HPV E6/E7 mRNA expression was significantly lower than HPV DNA positivity, the HPV E6/E7 mRNA assay showed greater specificity than the HPV DNA assay (88.6% vs. 48.1%) in normal cytology samples. The prevalence of Alpha-9 (HPV 16, 31, 33, 35, 52, and 58) HPV infection among these women accounted for up to 80.3% and 76.1% of the high-grade lesions detected in the HPV mRNA and DNA tests, respectively. The HR-HPV genotype distribution, based on HPV DNA and E6/E7 mRNA expression by age group in patients with cytologically confirmed lesions, was highest in women aged 40 to 49 years (35.9% for cytologically confirmed cases, Pearson correlation r value=0.993, p<0.001) for high-grade lesions. Among the oncogenic HR-HPV genotypes for all age groups, there was little difference in the distribution of HPV genotypes between the HPV DNA (HPV -16, 53, 18, 58, and 33) and HPV E6/E7 mRNA (HPV -16, 53, 33, 58, and 18) assays. HPV 16 was the most common HPV genotype among women with high-grade lesions. Conclusions: Our results suggest that the HPV E6/E7 mRNA assay can be a sensitive and specific tool for the screening and investigation of cervical cancer. Furthermore, it may provide useful information regarding the necessity for early cervical cancer screenings and the development of additional effective HPV vaccines, such as one for HPV 53 and 58. Additionally, gaining knowledge of HPV distribution may also inform us about ecological changes in HPV after the vaccination.
