Microbial lipopeptides play an important role in apoptosis induction of tumor cells. However, there is little knowledge about the relationship between apoptosis induction and membrane fatty acids. The present study focused on the effects of lipopeptides produced by Bacillus subtilis HSO121 on Bcap-37 cell lines. 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl (MTT) colorimetric assay and surface tension measurements, showed that the critical micelle concentration (CMC) was a critical level for the inhibitory activity of lipopeptides on the growth of Bcap-37 cells. Under the CMC, the order of least to greatest cytotoxicity effect on cancer cell lines by lipopeptides is C(13)-lipopeptide < C(14)-lipopepitde < C(15)-lipopeptide. Above CMC, all lipopeptides directly exert cytolytic activity. The flow cytometric analysis and Hoechst33258 staining experiments confirmed the apoptosis of Bcap-37 cell lines induced by lipopeptides in a dose-dependent manner. This apoptosis was associated with a significant decrease of the unsaturated degree of the cellular fatty acids of Bcap-37 cell lines due to the changes in the cellular fatty acids composition induced by the lipopeptide treatment. These results indicated that disturbance of the cellular fatty acid composition of breast cancer cell lines were related to in the cell apoptosis. Furthermore, significant difference in IC(50) values of tumor cells and normal cell showed that the lipopeptide exerted selective cytotoxicity on the cancer cells. Thus HSO121 lipopeptides may have potential applications as an anticancer leads.

Objective:To explore the risk factors of postpartum sepsis and provide references for clinical prevention of postpartum sepsis.Methods:The clinical data of postpartum patients who were treated and delivered in the maternity ward of Shengjing Hospital Affiliated of China Medical University from January 2016 to December 2018 were analyzed retrospectively. Among them, 99 patients with postpartum sepsis were assigned to the case group and 212 patients without postpartum sepsis in the same period were selected with a simple random method and as the control group. The clinical data of the two groups were collected by consulting the hospital electronic medical record system. Single factor and multivariate Logistic regression were applied to analyze the risk factors of postpartum sepsis.Results:The infection sites of 99 postpartum sepsis patients were mainly genital tract and respiratory system, accounting for 28.28% (28/99) and 26.26% (26/99), respectively. In blood culture of 99 cases of postpartum sepsis patients, 58.59% (58/99) pathogens of Gram-positive bacteria were detected with the highest proportion, among which Streptococcus was mainly, accounting for 23.23%(23/99). The proportion of Gram-negative bacteria was 38.38%(38/99), and Escherichia coli was mainly, accounting for 31.31% (31/99). Multivariate Logistic analysis showed that gestational diabetes ( OR = 2.643, 95% CI 1.123 - 6.276), genital tract infection ( OR = 7.542, 95% CI 3.571-15.959), vaginal trial (switch to cesarean section) ( OR = 1.218, 95% CI 1.008-1.493), premature rupture of membranes ( OR = 1.152, 95% CI 1.019 - 1.449), postpartum hemorrhage ( OR = 1.562, 95% CI 1.263 -1.881) and cesarean delivery ( OR = 2.074, 95% CI 1.442 - 2.993) were the risk factors of postpartum sepsis. Conclusions:The main risk factors affecting postpartum sepsis includes gestational diabetes, genital tract infection, vaginal trial (switch to cesarean section), premature rupture of membranes, postpartum hemorrhage and cesarean delivery. It is necessary to take corresponding intervention measures to strengthen prevention of these risk factors, which is of great significance for prevention and treatment of postpartum sepsis.

Objective:To evaluate the methodological quality and reporting quality of clinical practice guidelines or consensuses in the field of Chinese pancreatic diseases from 2016 to 2021, and provide reference for formulating clinical practice guidelines and consensuses in this field.Methods:VIP, Wanfang , CNKI and CBM databases were searched for articles published from January 2016 to March 2021. The main index terms were " pancreas" , " guideline" , " consensus" , and the supplementary index terms were " pancreatitis" , " pancreatic cancer" , " pancreatic head cancer" . Two researchers independently selected the literature. The appraisal of guidelines for research and evaluation (AGREE-China) was utilized to assess the methodological quality of the guidelines or consensuses, and the reporting items for practice guidelines in healthcare (RIGHT) tool was used to assess the reporting quality.Results:A total of 14 literature were included, including 7 literature on pancreatic cancer, 3 literature on acute pancreatitis, 1 literature on chronic pancreatitis and 3 literature on others. The results of the assessment by the AGREE-China tool showed that there were no document with a total score greater than or equal to 60.0 points, two with 40.0 to 59.9 points, eleven with 20.0 to 39.9 points, and one with less than 20.0 points. Among the results of RIGHT list, basic information was reported the highest(72.62%) and funding and declaration was the lowest(0).Conclusions:The methodological and reporting quality of the guidelines or consensuses on pancreatic disease in China from 2016 to 2021 are generally not high. In the process of developing domestic guidelines or consensuses on pancreatic diseases, the guideline developer should refer to AGREE-China and RIGHT to improve the quality of clinical practice guidelines or consensuses.

Objective To observe the reliving of the work stress in new nurses by emotion management training. Methods A questionnaire about work stress was conducted among 60 nurses working in a level three class A hospital. The questionnaires included stress source questionnaire, the positive and negative emotion scale, trait coping style questionnaire and so on. After survey, 10 classes emotion management training was conducted. Then after training, the other survey result was collected and the data were analyzed. Results The work stress of new nurses were mainly caused by nursing specialty and work issues, especially frequent shift work. The score of positive emotion and coping were apparently increased, while the score of negative emotion and coping were decreased after training with statistical significance compared with scores before training ( P<0. 05). Conclusions The emotion management training was helpful to improve the positive emotion management and trait coping style, so as to relieve their work stress.

Objective:To understand the attitudes toward sexual health education and its correlates among community-based older adults in Shanghai, China.Methods:From June 2020 to December 2022, a cross-sectional survey was conducted among community residents aged ≥50 in Shanghai through multi-stage sampling. The estimated sample size was 735. The questionnaire included sociodemographic characteristics, health characteristics, and history of sexual health education. The multivariable logistic regression model was used to assess the correlates of attitudes toward sexual health education among community-based older adults.Results:A total of 824 participants (489 males and 335 females) with age of (65.1±8.1) years were included, whose main age distribution was 60-69 years (45.3%). The prevalence of supporting sexual health education among older adults was 49.4% (45.2% of men and 55.5% of women). Males (a OR=0.61, 95% CI: 0.44-0.83), aged 70 years and older (a OR=0.62, 95% CI: 0.40-0.94), urban residents (a OR= 2.54, 95% CI: 1.81-3.58), self-reported very good or excellent health status (a OR=1.64,95% CI: 1.04-2.58), having depressive symptoms (a OR=0.37,95% CI: 0.15-0.85), and having a history of sexual health education (a OR=8.64 ,95% CI: 4.62-17.70) were associated with their attitude toward sexual health education. Conclusions:The proportion of community-based older adults in Shanghai who support sexual health education was not high. Their attitudes toward sexual health education were associated with their self-reported health status, depressive symptoms, and history of sex education. Health professionals and institutions should focus on community-based older adults with key characteristics and tailor interventions to promote the willingness to receive sexual health education among older adults in China and to promote the popularity of sexual health education in this population.

Objective:To understand the sexually active status among community-based older adults aged ≥50 years in Tianjin, China, and to explore the potential correlates.Methods:A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 was conducted between June 2020 and December 2022. The estimated sample size was 735. The survey collected questionnaire information through face-to-face interviews with investigators, including sociodemographic, health, and sexual lifestyle characteristics. The multivariable logistic regression model was used to assess correlates of sexually active status.Results:A total of 776 study participants (510 males and 266 females) were included, whose major age distribution was 50-59 years (45.9%). The overall sexual activity prevalence of the participants was 45.6%. Older age (60-69: a OR=0.67, 95% CI: 0.45-0.99; ≥70: a OR=0.12, 95% CI: 0.07-0.21), being male (a OR=1.93, 95% CI: 1.32-2.82), living in urban area (a OR=0.18, 95% CI: 0.12-0.28), living with spouse/married (a OR=2.80, 95% CI: 1.41-5.58), living alone (a OR=0.51, 95% CI: 0.27-0.96), having difficulty climbing stairs or walking (a OR=0.55, 95% CI: 0.31-0.97), having chronic diseases (one chronic disease: a OR=0.55, 95% CI: 0.36-0.85; two or more chronic diseases: a OR=0.53, 95% CI: 0.33-0.84) were associated with sexually active status among older adults. Conclusions:Many community-based older adults remained sexually active. There was an association between physical health and sexually active status among community-based older adults. Incorporating sexual health services into healthcare services for community-based older adults could be advocated, with a concurrent emphasis on enhancing the awareness and competence of providing sexual health services among community-based healthcare workers.
