A large proportion of patients with thyroid nodules in China undergo thyroidectomy in order to get confirmatory histology diagnosis. The financial impact of this modality remains to be investigated. To evaluate rationality of performing thyroidectomy without a routine FNA preoperatively from the economic perspective, we conducted a retrospective, observational study of all archival thyroidectomies with records of cost per stay (CPS), cost per day (CPD) and length of stay (LOS) from 2008 to 2013 in the First Affiliated Hospital of Nanjing Medical University. We compared all the parameters between cancer and non-cancer thyroidectomies. We recruited 6, 140 thyroidectomies with valid records of CPS, CPD and LOS in this period. The CPS of cancer thyroidectomy was significantly higher than non-cancer thyroidectomy. The percentage of cancer thyroidectomy increased from 26.5% to 41.6%. The percentage of annual cost of cancer thyroidectomies rose from 30.2% to 45.2%. The LOS for cancer and non-cancer thyroidectomy decreased while the CPD increased in the past six years. The estimated national cost in 2012 for all thyroidectomies would be USD 1.86 billion with USD 1.09 billion for non-cancer thyroidectomies. We have witnessed great improvement in the healthcare for patients with thyroid nodules in China. However, given limited healthcare resources, currently thyroid FNA for more precise preoperative diagnosis may help to curb the rapidly increasing demand in healthcare costs in the future for nodular thyroid disease in China.

Nerve growth factor(NGF) has a critical role in peripheral nerve regeneration. The aim of this study is to construct a well-functioning hNGF-$\beta$ recombinat adenovirus for the ultimate development of improved method to promote peripheral nerve regeneration with adenovirus mediated hNGF-$\beta$ gene transfection into Schwann cells. First PCR associated cloning of GFP-tagged hNGF-$\beta$ which was ligated into E1/E3 deleted adenoviral vector was performed and tranfected into E. coli to construct hNGF-$\beta$ recombinant adenovirus. After production of recombinat adenovirus in a large scale, its transfection efficiency, expression, and function were evaluated using cell lines or primarily cultured cells of HEK293 cells, Schwann cells, fibroblast(NIH3T3) and myocyte(CRH cells). GFP expression was observed in 90% of infected cells compared to uninfected cells. Total mRNA isolated from hNGF-$\beta$ recombinat adenoviru infected cells showed strong RT-PCR band, however, LacZ recombinant adenovirus infected or uninfected cells did not. NGF quantification by ELISA showed a maximal release of 18.865 +/- 0.31ng/mL at 4th day. PC-12 cells exposed to media with hNGF-$\beta$ recombinant adenovirus infected Schwann cell demonstrated higher levels of differentiation compared with controls. We generated hNGF-$\beta$ recombinant adenovirus and induced over expression of NGF successfully in nonneuronal and neuronal cells. Following these result, it is expected to develop an improved treatment strategy peripheral nerve regeneration using the hNGF-$\beta$ gene transfected cells.

The purpose of this study was to investigate the correlation between the knowledge and educational needs related to recurrent in coronary artery bypass graft patients as a basis to provide an individual nursing education for the population. The subjects consisted of 110 patients who had coronary artery bypass graft(CABG) at Asan Medical Center in Seoul and Sechong hospital in Buchon. Data was obtained from a knowledge questionnaire and a learning needs questionnaire between November 1998 and February 1999. Data were analyzed using SAS program for Wilcoxon rank sum test and Spearman correlation coefficient. The results were as follows : 1. With regard to the 18 items to measure knowledge, the mean (median) of items 'don't know' was 4.9(4) items. The mean (median) of items answered wrong was 3.2(3) items. The number of items answered 'don't know' tend to show higher in those who had less education, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension 2. With regard to the level of knowledge by questionnaire about CABG, The most "I dont know" (59.1%) highly response was 'He has to be treated with anticoagulant drug to prevent revasculized vessel from obstructing.' The seond highest response (56.4%) was 'If you were hypotensive, the coronary attack would collapse. 'During the hospitalized day, the patient has complete bedrest.' The highest error probability was cholesterol has not to intake.', 'After surgery, the sexual life is need controlled for 1 year. 3. The mean of educational needs was 3.38. With regard to the level of learning needs by sentence about CABG, 'Food that benefit heart disease', 'Recurrence possibility of heart disease', 'Management method of operation site', 'Risk symptom that visit hospital or report immediately' were higher than other sentenses. With regard to the level of learning needs by factor 'food(5 items)', 'disease(9 items)' and 'exercise(3 items)' showed the highest than other factors. The educational needs by patients characteristics tend to show higher in males, under the age of 49, middle or high school degree, previous experience of admission with coronary artery disease, history of myocardial infarction, expierience of PTCA, history of cerebro-vascular accident, previous expierience of smoking than in their counter parts. 4. The number of items answered 'don't know', wrong and correct weren't correlated with the level educational needs. As the results, the number of items answered 'don't know' tend to show higher in those who had less educated, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension .There were higher frequency of items answered 'don't know' on anti-thrombolitic theraphy, hypotension and pain relief. Also there were higher frequency of items answered wrong on bed rest period, cholesterol intake, and sexual life. Educational needs were higher in young age group, had previous experience of procesure and history of other disease. And when we educate CABG patients, education for diet, recurrence possibility of disease, management methods of operation site and risk symptom should be emphasized.

Purpose: Many studies have addressed a psychiatric analysis of self-injury patients who have self-injurious behavior and who have attempted suicide. Few studies on the injury characteristics of self-injury related trauma patients have been conducted. We analyzed the injury characteristics of self-injury patients. Methods: A retrospective review of the medical records extracted from the injury surveillance system of Wonju Christian Hospital for the period from August 2006 to February 2008 was conducted. Of the 121 cases extracted, 103 were included in this study. We analyzed the sex ratio, age group, place of injury, injury mechanism, location of injury, management results, injury severity, and relation with drinking. Results: One hundred three cases were included (sex ratio: 1.06), and the mean age was $33.9{\pm}14.2$ years old. Fifty-six patients (54.4%) were discharged from the emergency department (ED) on the day of injury after primary care, and 9 patients (8.7%) were discharged, because they refused treatment. Seven patients (6.8%) died. Of these, 4 patients (3.9%) died after attempted cardio-pulmonary resuscitation in the ED, 1 patient (1%) was dead on arrival, and 2 patients (1.9%) died after admission. Sixteen patients (15.5%) were admitted to the hospital, including 2 patients (1.9%) needing emergency surgery. Sixteen patients (15.5%) were transferred to other hospitals. Sixty-one cases (59.2%) involved drinking, and 31 (30.1%) did not; for 11 cases (10.7%), the involvement of drinking was unknown. The mean revised trauma score (RTS) was $11.26{\pm}2.52$, and 88 cases (85.4%) hat a RTS of 12. The mean injury severity score (ISS) was $5.80{\pm}14.56$, and 9 (8.7%) severely injured patients had scores of more than 15. Conclusion: Most self-injuries were mild traumas related to drinking and occurred at a young age. Most cases were not so severe, and the patients were discharged from the ED, but some patients needed hospitalization. Other patients had injuries so severe that they died.

Objectives: Cocaine has been well known as a representative drug of abuse for its strong reinforcing effect linked to the mesolimbic reward system including dopamine, and such reinforcement leads to the addiction. Acupuncture has been used widely in eastern Asia for the treatment of various diseases including mental disorders and psychiatric problems, and is gathering more interest as one of the complementary and alternative medicines in western countries. In a previous study, we demonstrated that acupuncture at HT7 could affect dopamine release in the mesolimbic system of rats sensitized to alcohol and morphine. This study was designed to investigate whether acupuncture at HT7 could attenuate cocaine intake or not. Material & Methods: Male Sprague-Dawley rats weighing 270-300 g at the start of experiment were trained to self-administer food pellets under a fixed ratio 1 schedule. After the success of acquisition of 100 pellets within 3 h for 3 consecutive days, animals were subjected to surgery whereby Silastic tubing was implanted into right jugular vein and secured with mesh under the anesthetization using pentobarbital injection (50 mg/kg, i.p.). Following recovery, rats were trained to self-administer cocaine (0.25 mg/kg) in daily 2 h sessions under fixed ratio 1 schedule over 10 days. Each treatment was performed on the next day of each establishment of baseline. Results: Results show that acupuncture at HT7, but not at control points, reduced cocaine intake significantly. Acupuncture at HT7 decreased selectively active lever response from $63.15{\pm}3.35$ to $51.46{\pm}3.99$ corresponding $82.12{\pm}5.31%$ compared to basal level. Also, it was demonstrated that the effect of acupuncture was mainly occurred at the half period. Nevertheless, acupuncture at HT7 did not influence the food taking behavior. Conclusions: From the results of this study, it may be suggested that acupuncture at HT7, at least in part, could contribute to the treatment of cocaine abuse.

The pathogenesis of cholestatic liver injury as well as the modulation of hepatic fibrogenesis is causally associated with involvement of reactive oxygen species (ROS) and free radical reactions. In this study, we investigated whether dried extracts of oriental medicine (LH) have antioxidant and antifibrotic effect under the biliary liver fibrosis (cirrhosis) c ondition. The female Sprague-Dawley rats were divided in six groups (Normal, N-LH, op-2, op-4, opLH-2, opLH-4) and were observed in 2 weeks or 4 weeks. For this purpose the rats were operated by bile duct ligation/scission (BDL/S), which induced to liver fibrosis and cirrhosis. After surgery, the prepared LH was administered p.o. 2 mι/day/rat in 2 weeks or 4 weeks for opLH groups. During the observation period, jaundices appeared in eyes, ears and tail of all BDL/S operated rats. And at the time of sacrifice, cholestasis was observed in proximal bile duct, especially the color of bile juice and urine in opLH-4 group showed more clear than op-2, op-4 and opLH-2 group. The value of clinical parameters and product of lipid peroxidation (MDA) in sera and the hydroxyproline (hyp) content in liver tissue were significantly increased in all liver fibrosis (cirrhosis) developed rats (p＜0.001~0.05). Among the clinical parameters of sera, value of BUN, ALP in opLH-4 group showed significantly lower than in op-4 group (p＜0.05, p＜0.001). The content of hyp in opLH-2, opLH-4 group (478.0 $\pm$ 134.3 $\mu\textrm{g}$/g 897.5 $\pm$ 118.2 $\mu\textrm{g}$/g) showed lower than in op-2, op-4 group (528.9 $\pm$ 220.7 $\mu\textrm{g}$/g, 1023.8 $\pm$ 277.1 $\mu\textrm{g}$/g) and then the value of MDA in opLH-4 was also significantly reduced to 59.4% of that in op-4 group (p＜0.001). The histological change (bile duct proliferation, fibrosis, collagen bundle) was similarly observed in op-2 group and in opLH-2 group, but the weak fibrosis and bile duct proliferation were observed in opLH-4 group compared with in op-4 group. Our data indicate that the 4 weeks treatment with LH extract suppressed lipid peroxidation and inhibited fibrotic (cirrhosis) process, and experimental cholestatic liver disease is associated with increased lipid peroxidation in BDL/S operated rats. Hence we concluded that the measurement of MDA and hyp can be useful monitor for the screening of antioxidant and antifibrotic effect in experimental liver fibrosis (cirrhosis), and LH has been shown to have hepatoprotective effect, antifibrotic effect and antioxidant effect.

Forty-two percent of the patients with renal failure that requires continuous renal replacement therapy (CRRT) have been reported to have severe malnutrition, and preexisting malnutrition is a statistically significant and independent predictor of negative hospital outcomes. We performed this study to evaluate the appropriateness of the calorie and protein provided for the critically ill patients who require CRRT. One hundred forty-nine patients who received CRRT were enrolled. The demographic data, the length of the ICU stay and the mortality were recorded. The calorie/protein intake and the blood urea nitrogen (BUN), albumin and creatinine levels were used as nutritional parameters. The mean daily calorie intake during CRRT was 16.1${\pm}$7.4 kcal/kg, which was 64% of the recommended intake. Only 10% of the patients received the recommended caloric intake and the ratio of the enteral and parenteral calories was 26%/74%. The mean protein intake was 0.58${\pm}$0.34 g/kg, which was 38% of the recommended intake. The calorie and protein intakes at the termination of CRRT were significantly increased compared to the initial day of treatment, but they stayed under the recommended intake. The BUN, creatinine and albumin levels were significantly increased in the survival group (odds ratio for albumin: 2.73; creatinine: 2.43). A strategy to increase the nutrition provision is needed to improve the nutritional statuses and clinical outcomes of the critically ill patients who require CRRT.
