Among those positive patients, 67 cases belonged to stricture of the lower biliary tract; 5 cases were Mirizzi syndrome; 2 cases were carcinoma of the periampulla; 1 case was primarily carcinoma of the bile duct; 1case was ascarisis of the biliary system. Conclusions IOCF is a good inspect technique with high success rate and clear image of bile duct, it can discover the common duct diseases which are difficult to be diagnosed through the routine examination.At the same time, it can provide the locative and qualitive diagnosis, determine reasonable methods of operation,and effectively provent postoperative complications.

AIM: To observe the effect of exogenous androgen responsive element decoy on the promoter of prostate specific antigen (PSA) and the growth of LNCaP cells for searching the possibility of gene therapy for prostate cancer. METHODS: Firstly, pGL3 - PSA luciferase expression vector containing 640bp - promoter fragment of PSA gene was constructed. Then, a 23 -mer phosphorothioated ARE decoy based on the deduced ARE sequence at the promoter region of PSA gene was synthesized. pGL3 - PSA and ARE decoy DNA were cotransfected into PC3 - M cell by lipofectamineTM 2000. Through detecting the activity of luciferase, the effect of ARE decoy on the promoter of PSA was studied. Then the ARE decoy DNA was transfected into LNCaP cells. The effect of decoy DNA on the proliferation of LNCaP cells was examined by using MTT assay. The effects of apoptosis were detected by phase contrast microscopy, DNA agrose gel electrophoresis and flow cytometry. Meanwhile, the nuclear extract was prepared from LNCaP cells and DNA - protein interactions were examined by electrophoretic mobility shift assay (EMSA). RESULTS: The reporter assay showed that the aetivity of luciferase was significantly reduced in the ARE decoy - transfected cells, bnt not in the cells transfected with the control decoy. EMSA demonstrated specific binding of the ARE decoy to androgen receptor. The growth of LNCaP was remarkably inhibited and apoptotic morphological changes as well as DNA fragmentation were observed in the ARE decoy- transfected cells. The rate of apoptosis was 22.4% detected by FCM. CONCLUSION: The ARE decoy is capable of inhibiting the promoter of PSA gene and inducing the apoptosis in prostate cancer cells. It may become a potential therapeutic tool for prostate cancers.

Objective To observe the effect of rotavirus (RV) infection on expression level and bioactivity of Na+-H+ exchanger 3 (NHE3) in Caco-2 cells. Methods Model of NHE3-expressing Caco-2 cells was constructed and studied in terms of intervention: control, RV, clathrin antagonist chlorpromazine (CPZ), and CPZ + RV. NHE3 activity and NHE3 protein amount on cell surface were determined by BCECF-AM and biotinylation, respectively. Expression level of clathrin was assayed by Western blot. Results Compared with control group, NHE3 activity and NHE3 surface protein level significantly decreased when the cells were treated with RV. These effects could not be completely cancelled by clathrin antagonist CPZ. Moreover, RV treatment could increase cellular protein level of clathrin, which was cancelled by CPZ. Conclusions The effect of RV infection on NHE3 expression level and biological activity may be related to clathrin-dependent endocytosis pathway, and may be also affected by other endocytosis pathways.

Scutellaria baicalensis is an important traditional Chinese medicine and Scutellaria flavonoids have received worldwide attention in recent years. It is the basis of controlling quality of S. baicalensis to develop a reliable genetic marker system used to identify locality of origin. Because of the characteristics of maternal inherited and high-rate of evolution, the cpDNA intergenic spacer can effectively elucidate the degree of genetic variation in different areas of the same species (populations), which can be used as the population-level DNA barcoding to locality identify. In this study, we have used the molecular phylogeography analysis for the three cpDNA intergenic spacers atpB-rbcL, trnL-trnF and psbA-trnH of 17 wild populations from different localities, which reveals the 20 haplotypes, including 13 polymorphic sites and constitutes a shallow gene tree. The authers have divided the haplotypes of S. baicalensis into three grades of population-level DNA barcoding according to the frequence and geographic distribution: 3 highest-frequency haplotypes as area-population-level DNA barcoding, 3 haplotypes were mainly shared by 2-3 adjacent populations as region-population-level DNA barcoding, and there are also 8 unique-population haplotypes as unique-population-level DNA barcoding. The result of this study reveals that population-level DNA barcoding is a reliable genetic marker used to locality identify of S. baicalensis.

Objective? To investigate the leadership status of new nurses, and to provide some reference for the training and education of new nurses and efficient quality nursing service. Methods? In September 2018, a total of 129 new nurses from a ClassⅢ Grade A hospital were randomly recruited by convenience sampling method. Questionnaire survey was conducted to compare the difference of leadership among new nurses with different characteristics by General Information Questionnaire and Nurse Leadership Questionnaire. A total of 129 questionnaires were sent out and 125 valid questionnaires were collected. Results? The average leadership score of the 125 new nurses was (3.59±0.67). The score of nursing professional ability dimension was the highest (3.73±0.64), and the score of critical thinking ability dimension was the lowest (3.47±0.71). The scores of five dimensions of interpersonal communication ability, communication ability, critical thinking ability, planning and organizing ability and self-care ability of new nurses of different genders in the nurse leadership questionnaire were compared, and the differences were statistically significant (t=-3.950,-3.145,-3.389,-3.451,-2.179;P＜0.05). The difference in critical thinking ability score of new nurses with different marital status was statistically significant (t=3.235,P＜ 0.01). Conclusions? The overall level of leadership status of new nurses is low. It is suggested that in the standardized training and education of newly recruited nurses, early education and training of career leadership should be emphasized, and the strengths of different groups of nurses should be brought into play, so as to improve their professional value and quality service.

Objective:To explore the current status and influencing factors of psychological resilience in in-service nurses in Hunan Province, and provide a certain reference for the development of nursing human resource management and occupational mental health.Methods:A mixed study method was adopted. Quantitative study: in August 2018, a total of 749 in-serve nurses from hospitals in Hunan Province were selected by convenient sampling and investigated with the general information questionnaire and Conner-Davidson Resilience Scale (CD-RISC) . SPSS 23.0 was used for statistical analysis. Qualitative study: totally 21 in-service nurses who participated in the quantitative study were randomly selected for semi-structured interviews. Based on the principle of data saturation, the subject analysis method was used to organize the data.Results:The total CD-RISC score of the 749 in-service nurses was (87.28±13.28) , higher than (65.40±13.90) of the domestic norm, and the difference was statistically significant ( P<0.01) ; the average score of each dimension in descending order was (3.69±0.55) for strength, (3.41±0.58) for toughness, and (3.34±0.60) for optimism. There were statistically significant differences between the total CD-RISC score of in-service nurses with different ages, educational levels, working years, type of affiliation, form of employment, and professional title ( F=7.295, 5.446, 6.915, 3.238, 4.342, 7.914; P<0.05) ; Multi-factor analysis showed that age and education level were the main influencing factors ( P<0.05) . Two themes were extracted from the qualitative study, namely internal factors and external factors. The internal factors included the lack of personal adaptability and mental health guidance awareness, while the external factors included differences in hospital management culture, and lack of psychological service institutions, professionals and trust. Conclusions:The psychological resilience of in-service nurses in Hunan Province is higher than that of domestic norms, and is affected by both internal and external factors. It is recommended to enhance the nurses' rights protection bill in future organization and management, attach importance to their on-the-job education and provide personalized psychological service channels for employees, and further strengthen the hospital's internal psychosocial service construction.

ObjectiveTo conduct a systematic comparative study on wild and cultivated Codonopsis pilosula（CP） from three aspects， including characters， microscopy， and contents of primary and secondary metabolites. MethodWild and cultivated CP samples were collected， their characters were measured using vernier caliper， tape measure and balance， the paraffin sections were stained with safranin-fixed green dyeing， and their microstructure were observed under the optical microscope. The content of alcohol-soluble extracts in wild and cultivated CP was determined according to the method for determination of extract under CP in the 2020 edition of Chinese Pharmacopoeia， the starch content was determined by anthrone colorimetry， the content of total polysaccharides was determined by kit method， Fiber analyzer was used to determine the content of fiber components， and ultra performance liquid chromatography（UPLC） was used to determine the content of monosaccharides， disaccharides and some secondary metabolites. Multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were employed to screen key differential components between wild and cultivated CP on the basis of variable importance in the projection（VIP） value>1 and P<0.05. ResultIn terms of morphological characteristics， the "lion's head-like" shape， longitudinal wrinkles， and circumferential wrinkles below the root cap of wild CP were more pronounced in wild CP compared to the cultivated ones. Regarding transverse sectional features， wild CP had more fissures on the outer side of the cortex and a larger duramen. Under microscopic examination， wild CP had more stone cells， a larger proportion of xylem， and the presence of cork cells arranged in rings in the xylem， while cultivated CP has a larger proportion of phloem， smaller vessel diameters， and a more loosely arranged vascular system. In terms of primary metabolites， the contents of 45% ethanol-soluble extract and total polysaccharides in cultivated CP were significantly higher than those in the wild ones（P<0.05）， the contents of lignin， hemicellulose， cellulose， fructose and glucose in wild CP were significantly higher than those in the cultivated ones（P<0.05）， while sucrose content in the cultivated CP was significantly higher than that in the wild ones（P<0.05）. Concerning secondary metabolites， the contents of tryptophan and tangshenoside Ⅰ in cultivated CP were significantly higher than those in the wild ones（P<0.05）， whereas the contents of lobetyolinin， lobetyol and atractylenolide Ⅲ in wild CP were significantly higher than those in the cultivated ones（P<0.05）. ConclusionThere are significant differences between wild and cultivated CP in terms of morphological characteristics， microscopic features and chemical composition. Glucose， fructose， sucrose， tangshenoside Ⅰ， tryptophan and cellulose components are the key differential components between wild and cultivated CP. Wild CP contains more polyacetylenes and fructose， whereas cultivated CP has higher levels of tangshenoside Ⅰ and sucrose， with noticeably lower cellulose content. These distinctions may be related to their growth conditions， growth years and cultivation techniques. Based on the results of this study， it is recommended to increase polyacetylenes and the content ratio of fructose to sucrose as an indicators to characterize different production methods of CP， in order to guide the high-quality production of CP.
