Objectives To evaluate the evidence supporting the efficacy and safety of electroacupuncture for lumbar spinal stenosis. Methods We searched eight electronic databases (PubMed, EMBASE, Cochrane Library, Chinese Academic Journals, Research Information Sharing Service, ScienceOn, KMBASE, DBpia) and related two journals up to March 2023. We included randomized controlled trials of testing electroacupuncture for lumbar spinal stenosis patients. The methodological quality of relevant randomized controlled trials assessed by the Cochrane risk of bias tool. Results Among 90 articles that were searched, seven randomized controlled trials involving 474 participants were finally selected in this systematic review. Electroacupuncture was more effective on lumbar spinal stenosis compared with other treatments including analgesics, acupuncture, bed rest and exercise therapy, but showed ambiguous effect compared with physical therapy. Most of the side effects and adverse reactions were reported as minor and temporary. Conclusions Electroacupuncture for lumbar spinal stenosis was more effective than analgesics, acupuncture, bed rest and exercise therapy. In terms of safety, it was limited because there are many papers that do not mention side effects and adverse reactions related to electroacupuncture. Additional studies are needed to determine the effect of electroacupuncture on lumbar spinal stenosis.

Purpose: This review explored the status of publications on intimate partner violence (IPV) against pregnant women in contemporary China. Methods: The PubMed, Cochrane Library, Embase, CINAHL, and PsycInfo databases were searched using the terms "IPV," "pregnant woman," "Chinese," and synonyms in English, along with related keywords for Chinese publications. All literature pertaining to IPV during pregnancy, conducted in China, and published between 1987 and September 2023 was included. Results: A total of 37 articles from 30 studies were selected. The prevalence of IPV during pregnancy ranged from 2.5% to 31.3%, with psychological violence being the most common form. Frequently identified risk factors included unintended pregnancy, poor family economic conditions, male partners engaging in health risk behaviors, poor employment status of women or their partners, low education levels among women, physical or mental health issues, strained couple relationships, and in-law conflicts. IPV during pregnancy primarily led to mental health problems for the victims and could result in adverse obstetric outcomes, as well as negative effects on the temperament and development of the offspring. Victims in China demonstrated a low willingness to seek help from professionals. Furthermore, relevant research in mainland China is scarce, with a limited number of studies and non-standardized research methodologies. Conclusion: Future research should investigate IPV in pregnancy from various perspectives, identify factors unique to IPV during pregnancy, and focus on high-risk groups. Considering the conditions in China, there is a pressing need to increase public awareness of IPV and to investigate interventions aimed at addressing this issue.

유전체 연구란 목적하는 유전체의 구조를 밝히고 가지고 있는 모든 유전자의 기능 및 진화과정을 망라하여 이해하고자 하는 것이다. 계통발생학상 애기장대와 연관되어 있는 Brassica rapa는 채소, 유지 및 사료로 이용되는 중요한 작물의 하나이다. Brassica rapa의 유전체 연구를 착수하는 데는 적합한 유전학적 재료 및 유전체 재료가 있어야 한다. 우리는 배추 (Brassica rapa spp. pekinensis)를 재료로 하여 표준 mapping 집단을 개발하여, 78계통으로 구성된 DH집단과 약 250 계통으로 구성된 RI집단을 개발하였다. 2가지 제한효소 (HintIII, BamHI)를 이용해 세균인공염색체 (BAC) library (KBrH, KBrB)를 만들었고, 이들은 각각 56,592개와 50,688개의 클론으로 구성되어 있다. 또한 배추의 각기 다른 부위를 이용하여 만든 22가지의 cDNA library를 이용하여 평균 575bp의 길이를 가지는 104,914개의 EST 분석을 실시 하였다. 세계적으로 'Multinational Brassica Genome Project (MBGP)' 조직이 구성되었고 배추의 전 염기서열 분석을 하기로 2003년 결정되었다. 그 첫 단계로 104,914개의 BAC 클론의 BAC-end 염기서열분석이 제안되어 2006년 9월 5개국 공동 프로젝트로 추진하여 완성하게 되었다. 이러한 BAC-end 염기서열분석의 결과는 유전자의 염기서열 해석, 및 풍부하게 존재하는 반복염기서열 DNA를 분석함으로써 배추의 유전체 구조를 이해할 수 있는 실마리를 주었다. BAC 클론의 전체 염기서열분석은, 비록 단편 내에 유전자의 결실이 변화무쌍하게 일어나지만 배추 DNA 단편이 유전체에서 광범위하게 삼중복으로 존재함을 나타냈다. 이러한 BAC-end 염기서열을 아기장대 염기서열에 비교하여 629개의 종자 BAC을 선정하게 되었고, 이들의 염기서열 분석을 완성하였다. MBGP에서는2단계로서 배추의 전 유전체 염기서열 분석을 추진하게 되었고, 유전자지도에 위치한 종자 BAC을 이용하여 인접한 BAC 클론을 찾아 염기서열 분석하는 BAC-to-BAC 방법을 추진하고 있으며 8개국에서 참여하여 현재 염기서열 분석을 추진 중 이다. 최근에 각 국에서는 생물정보학기법을 활용한 염기서열 분석 기반에 대하여 많은 토론이 진행되고 있다. 앞으로 다양한 유전체 정보가 축적됨에 따라 배추의 유전체 구조를 이해하고 농업적으로 적용하고자 하는데 기여를 할 것이다.

Human and monogastric animals can not synthesize 10 out of the 20 amino asids and therefor need to obtain these from their diet. The plant seed is a major source of dietary protein. It is particular important in their study to increase nutritional quality of the seed storage proteins. The low contents of lysine, asparagine and threonenein various cereal seeds and of cystein and methionine. In legume seeds is due to the low proportions of these amino acids in the major storage proteins, we have tried to apply the three strategies; (1) mutagenesis and selection of specific amino acid analogue resistance, (2) cloning and expression study of lysine biosynthesis related gene, (3) transfomation of lysine rich soybean glycinin gene. The 5-methyltryptophan (5MT) resistant cell lines, SAR1, SAR2 and SAR3 were selected from anther derived callus of rice (Oryza sativa L. "Sasanishiki"). Among these selected cell lines, two (SAR1 and SAR3) were able to grow stably at 200 mg/L of 5MT. Analysis of the freed amino acids in callus shows that 5MT resistant cells (SAR3) accumulated free tryptophan at least up to 50 times higher than those that of the higher than of SAS. These results indicated that the 5MT resistant cell lines are useful in studies of amino acid biosynthesis. Tr75, a rice (Oryza sativa L., var. Sasanishiki) mutant resistant to 5MT was segregated from the progenies of its initial mutant line, TR1. The 5MT resistant of TR75 was inherited in the M8 generations as a single dominant nuclear gene. The content of free amino acids in the TR75 homozygous seeds increased approximately 1.5 to 2.0 fold compared to wild-type seeds. Especially, the contents of tryptophan, phenylalanine and aspartic acid were 5.0, 5.3 and 2.7 times higher than those of wild-type seeds, respectively. The content of lysine is significantly low in rice. The lysine is synthesized by a complex pathway that is predominantly regulated by feedback inhibition of several enzymes including asparginase, aspatate kinase, dihydrodipicolinat synthase, etc. For understanding the regulation mechanism of lysine synthesis in rice, we try to clone the lysine biosynthetic metabolism related gene, DHPS and asparaginase, from rice. We have isolated a rice DHPS genomic clone which contains an ORF of 1044 nucleotides (347 amino acids, Mr. 38, 381 daltons), an intron of 587 nucleotides and 5'and 3'-flanking regions by screening of rice genomic DNA library. Deduced amino acid sequence of mature peptide domain of GDHPS clone is highly conserved in monocot and dicot plants whereas that of transit peptide domain is extremely different depending on plant specie. Southern blot analysis indicated that GDHPS is located two copy gene in rice genome. The transcripts of a rice GDHPS were expressed in leaves and roots but not detected in callus tissues. The transcription level of GDHPS is much higher in leaves indicating enormous chloroplast development than roots. Genomic DNA clones for asparaginase genes were screened from the rice genomic library by using plaque hybridization technique. Twelve different genomic clones were isolated from first and second screening, and 8 of 12 clones were analyzed by restriction patterns and identified by Southern Blotting, Restriction enzyme digestion patterns and Southern blot analysis of 8 clones show the different pattern for asparaginase gene. Genomic Southern blot analysis from rice were done. It is estimated that rice has at least 2-3 copy of asparaginase gene. One of 8 positive clones was subcloned into the pBluescript SK(+) vector, and was constructed the physical map. For transformation of lysine rich storage protein into tobacco, soybean glycinin genes are transformed into tobacco. To examine whether glycinin could be stably accumulated in endosperm tissue, the glycinin cDNA was transcriptionally fused to an endosperm-specific promotor of the rice storage protein glutelin gene and then introduced into tobacco genomic via Agrobacterium-mediated transformation. Consequently the glycinin gene was expressed in a seed-and developmentally-specific manner in transgenic tobacco seeds. Glycinin were targeted to vacuole-derived protein bodies in the endosperm tissue and highly accumulated in the matrix region of many transgenic plant (1-4% of total seed proteins). Synthesized glycinin was processed into mature form, and assembled into a hexamer in a similar manner as the glycinin in soybean seed. Modified glycinin, in which 4 contiguous methionine residues were inserted at the variable regions corresponding to the C - teminal regions of the acidic and basic polypeptides, were also found to be accumulated similarly as in the normal glycinin. There was no apparent difference in the expression level, processing and targeting to protein bodies, or accumulation level between normal and modified glycinin. glycinin.

당근(Daucus carota L. var. sativa)은 세계적으로 광범위하게 사용되는 채소 작물 중 하나로 비타민 A 카로티노이드의 전구체로 잘 알려진 베타카로틴이 다량 함유되어 있어 영양학적으로도 중요한 작물이다. 하지만 당근 종자는 종피의 epidermal 세포에서 연장되는 형태로 생성되는 종자모의 캐로톨 등과 같은 다양한 요인들에 의해 종자의 수분흡수와 발아가 억제된다. 따라서 당근 종자를 상품화하기 이전에 기계적인 종자모 제거과정을 거쳐야 하며 이러한 과정 때문에 생산자는 종자의 물리적인 손실은 물론 시간과 노동력, 그리고 자본금과 같은 추가적인 손실을 감수해야만 한다. 그리고 종자의 물리적인 손실은 종자발아율을 불균일하게 한다. 이러한 문제점들을 보완하기 위해서 무모종자 당근품종 개발을 위한 육종이 필요하게 되었으며 이러한 육종과정을 위해 종자모 형질관련 분자표지에 관한 연구가 필요하게 되었다. 이에 따라, 본 연구에서는 단모종자 표현형 CT-SMR 616 OP 659-1 개체와 유모종자 표현형 CT-SMR 616 OP 677-14 개체, 그리고 단모종자 표현형 CT-ATR 615 OP 666-13 개체와 유모종자 표현형 CT-ATR 615 OP 671-9 개체의 cDNA library를 각각 작성하였다. 또한 각각의 개체별로 1,248개의 EST, 합계 4,992개의 EST를 sequencing하였다. 단모종자와 유모종자 개체의 EST sequence들을 2개의 조합에서 각각 비교 분석하여 19개의 SNP site, 14개의 SNP site를 확인하였으며 이를 바탕으로 SNP site에 대한 High Resolution Melting 분석을 위한 프라이머를 작성하였다. 작성된 HRM 프라이머들은 유모종자 표현형 CT-SMR 616 OP 1040 개체군과 무모종자 표현형 CT-SMR 616 OP 1024, 1025, 1026 개체군을 이용하여 확인하였다. 그 중 한세트의 HRM 프라이머에서 유모 및 단모종자 표현형 개체군들의 melting curve간 특이적 다형성을 확인하였다. 이러한 결과를 바탕으로 유모종자 당근 및 단모종자 당근간의 보다 간편한 선발을 위해 allele-specific PCR 프라이머를 작성하였다. 이러한 HRM 및 AS-PCR 결과는 무모종자 당근육종에 있어 유용한 분자표지로써 사용될 수 있을 것이라 기대된다.

Rumen microbiology research has undergone several evolutionary steps: the isolation and nutritional characterization of readily cultivated microbes; followed by the cloning and sequence analysis of individual genes relevant to key digestive processes; through to the use of small subunit ribosomal RNA (SSU rRNA) sequences for a cultivation-independent examination of microbial diversity. Our knowledge of rumen microbiology has expanded as a result, but the translation of this information into productive alterations of ruminal function has been rather limited. For instance, the cloning and characterization of cellulase genes in Escherichia coli has yielded some valuable information about this complex enzyme system in ruminal bacteria. SSU rRNA analyses have also confirmed that a considerable amount of the microbial diversity in the rumen is not represented in existing culture collections. However, we still have little idea of whether the key, and potentially rate-limiting, gene products and (or) microbial interactions have been identified. Technologies allowing high throughput nucleotide and protein sequence analysis have led to the emergence of two new fields of investigation, genomics and proteomics. Both disciplines can be further subdivided into functional and comparative lines of investigation. The massive accumulation of microbial DNA and protein sequence data, including complete genome sequences, is revolutionizing the way we examine microbial physiology and diversity. We describe here some examples of our use of genomics- and proteomics-based methods, to analyze the cellulase system of Ruminococcus flavefaciens FD-1 and explore the genome of Ruminococcus albus 8. At Illinois, we are using bacterial artificial chromosome (BAC) vectors to create libraries containing large (>75 kbases), contiguous segments of DNA from R. flavefaciens FD-1. Considering that every bacterium is not a candidate for whole genome sequencing, BAC libraries offer an attractive, alternative method to perform physical and functional analyses of a bacterium's genome. Our first plan is to use these BAC clones to determine whether or not cellulases and accessory genes in R. flavefaciens exist in clusters of orthologous genes (COGs). Proteomics is also being used to complement the BAC library/DNA sequencing approach. Proteins differentially expressed in response to carbon source are being identified by 2-D SDS-PAGE, followed by in-gel-digests and peptide mass mapping by MALDI-TOF Mass Spectrometry, as well as peptide sequencing by Edman degradation. At Ohio State, we have used a combination of functional proteomics, mutational analysis and differential display RT-PCR to obtain evidence suggesting that in addition to a cellulosome-like mechanism, R. albus 8 possesses other mechanisms for adhesion to plant surfaces. Genome walking on either side of these differentially expressed transcripts has also resulted in two interesting observations: i) a relatively large number of genes with no matches in the current databases and; ii) the identification of genes with a high level of sequence identity to those identified, until now, in the archaebacteria. Genomics and proteomics will also accelerate our understanding of microbial interactions, and allow a greater degree of in situ analyses in the future. The challenge is to utilize genomics and proteomics to improve our fundamental understanding of microbial physiology, diversity and ecology, and overcome constraints to ruminal function.

This historical research was conducted to analyze and categorize the titles which were presented in the journal, The Korean Nurse, from August 1962 to October 1995. Titles which were published with the purpose of educating graduate nurses and to update 0 their nursing knowledge to improve professional practice were included. There were 348 articles published from the beginning of publication in August, 1962 to October, 1995. All of the journals were reviewed except nine missing journals which were not available in any library. According to the characteristics of the articles in the periodical, the articles were divided into three periods. In each of the three peroids there were five categories: Subject, Clinical Practice, Fundamentals of Nursing Science, Nursing Administration, Others. These categories were adopted from Kim's(1994) division system which was developed to analyze nurse's insurance education program. The special feature peroid was from August, 1962 to December, 1974. In this period the articles were presented in an unorganized manner in the area of special feature or main issue. The largest area was the subject category(44%). The second largest area wes the fundamental of nursing science category(31%). From May, 1975 to December, 1977, the articles with the educational purposes were published in a designated area called continuing education. This period was labelled as the continuing education period. Among the published articles in this period, 45% focused on the subject category and 45% on the fundamentals of nursing science category. In this period the articles were focusing on nurses 'work in specific areas such as industry, nurses' aid schools, and nursing administration, articles on physical assessment first started to appear. The written continuing education period was from January 1978 to October, 1995. All the educational articles published in this area were analyzed and categorized into five areas as for the other periods. 48% of the articles focused on the subject category. In the mid-eighties, the term nurse specialist first.appeared and ten years later in 1990, the titles were subdivided into more specific titles, such as, home nursing, industrial nursing, emergency nursing, 23% were in the fundamental nursing science category and they dealt with nursing process, nursing theories, theory development. For the content analysis, three articles, one from each period, dealing with cardiovscular diseases were selected for comparsion. First, the special feature period, the title of the article was on diet therapy for cardiovascular disease patients, but instead the content was about rest, hygiene, medication, observation. They recommended rings to prevent bed sores, which is now considered as a cause for bed sores. In the continuing education period, the content was more focused on rehabilitation rather than general nursing .care. It became more specific, systematic, and organized compared with the special feature period. In the written continuing education period, the focus was on rehabilitation, not broadly, but very specifically on exercise. The further research on the content analysis is recommended along with a comparison of the trends in the Journal of Nurses Academic Society.
