Objective To analyze the epidemiological characteristics of aggregative vomiting and diarrhea outbreak in Jing'an District of Shanghai in 2017 and 2018，and provide data support for further development of effective prevention and control measures. Methods A descriptive epidemiological method was used to analyze aggregative vomiting and diarrhea outbreak data in Jing'an District in 2017 and 2018. Results A total of 49 outbreaks were reported in Jing'an District in 2017 and 2018，involving 565 cases，with the overall attack rate of 1.89%. The median duration of the outbreak was 5 days and outbreaks mainly occurred in spring and autumn. The attack rate in kindergartens was higher than that in primary and secondary schools, while the total number of outbreak cases in kindergartens was less. The main clinical symptoms of the cases were vomiting, with a higher proportion than that of diarrhea and fever. The vomiting proportion was higher in kindergartens and elementary schools, while the diarrhea proportion was higher in middle schools. Conclusion There were some differences in the epidemic characteristics between kindergartens and primary and secondary schools, therefore different control measures should be adopted according to the characteristics of different institutions. The outbreaks were mainly spread through human-to-human transmission. Early detection and early reporting of epidemics in collective institutions had a positive impact on the control of the spread of the epidemic.

Objective: To investigate the effect of compound sophora flavescens injection on T helper cells 17 (Th17), regulatory T-cells (Treg cells) and the related cytokines in lung cancer patients with cirrhosis. Methods: A total of 63 patients with early non-small cell lung cancer and cirrhosis in Shouguang People's Hospital of Shandong Province from January 2016 to January 2018 were selected. All patients were scheduled to undergo surgical treatment. The patients were randomly divided into observation group (33 cases) and control group (30 cases) according to the random number table method. The patients in the control group were treated with liver protection, and the patients in the observation group were given compound sophora flavescens on the basis of the control group. After 3 months of treatment, the changes of liver fibrosis index, the levels of Th17 and Treg cells in peripheral blood and the changes of interleukin (IL)-10, IL-17, IL-6, and transforming growth factor (TGF)-β in serum were compared between the two groups. Results: After treatment, the alanine aminotransferase (ALT) of 15 cases (45.45%) in the observation group were normalized and 6 cases (20.00%) in the control group were normalized. There was a significant difference in ALT normalization rate between the two groups (P < 0.05). The levels of serum laminin (LN) and hyaluronic acid (HA) in the two groups after treatment were lower than those before treatment (all P < 0.05), and the serum LN [(156.74±30.52) ng/ml] and HA [(179.56±25.32) ng/ml] in the observation group after treatment was lower than those in the control group [(210.58±39.42) ng/ml and (203.75±28.79) ng/ml] (t values were 18.236 and 12.184, both P < 0.01). There was no significant difference in the level changes of type Ⅲ procollagen and type Ⅳ collagen between the two groups before and after treatment (all P > 0.05). After treatment, the levels of Th17 and Th17/Treg increased and the level of Treg cells decreased (all P < 0.05). After treatment, the levels of Th17 [(1.32±0.18)%] and Th17/Treg (0.23±0.04) in the observation group were higher than those in the control group [(1.21±0.17)% and 0.20±0.03] (t values were 3.201 and 1.087, both P < 0.01), while the level of Treg cells in the observation group was lower than that in the control group (P < 0.05). After treatment, the serum levels of IL-10, IL-17, IL-6, and TGF-β in the two groups were lower than those before treatment (all P < 0.05), and their levels in the observation group were lower than those in the control group (all P < 0.05). Conclusion Compound sophora flavescens injection can improve the liver function and fibrosis index of patients with lung cancer and cirrhosis, and it can regulate the levels of Th17, Treg cells and their related factors, which can be used as a clinical adjuvant.

Objective: To investigate the current status of knowledge and attitudes of oncology nursing staffs on pain management in cancer patients. Methods: A total of 232 oncology nursing staffs from 7 Grade III-A Hospitals in 4 provinces and municipalities were surveyed using General Information Questionnaire and knowledge and attitudes survey regarding pain (KASRP) (2014) questionnaire (Chinese version). Results: The results of this survey showed that the average score of knowledge and attitude about pain management of 232 oncology nursing staffs was (21.56±4.01) points, and the average correct rate was 52.59%. There were no significant differences in the scores of different education background, years of nursing work, years of cancer clinical nursing care, and the nature of the hospital they worked in(P>0.05). However, there was a difference in the score of nursing staffs with different professional titles (F=5.885, P=0.003). Besides that, difference also showed in scores of nursing staffs with different experiences in caring cancer pain patients (F=3.216, P=0.024). Conclusion The knowledge and attitude of pain management in oncology nursing staffs are in low level, the command of knowledge is not enough, meanwhile, the pain management ability is insufficient. Therefore, it is necessary to strengthen the training of pain related knowledge of nursing staffs and improve their pain management ability.

Objective To investigate health beliefs and fluid status in diabetic peritoneal dialysis patients, to explore the relation between fluid status and health beliefs in diabetic peritoneal dialysis patients. Methods The data were collected from the peritoneal dialysis center in Ningxia Medical University General Hospital from January 2014 through January 2015. A total of 64 diabetic peritoneal dialysis patients were recruited and investigated with health beliefs scale, fluid status and laboratory index, the influencing factors were analyzed with Logistic regression. Results Levels of perceived barriers in diabetic peritoneal dialysis patients was the lowest. The score of perceived barriers, levels of albumin and daily water intake in pedal edema diabetic peritoneal dialysis patients were 35.34±10.31, (29.90±4.51) g/L,(860.34±516.71) ml/d, and the results in the non-pedal edema patients were 31.67±12.47, (32.72±6.87) g/L, (872.22±271.85) ml/d, the difference was significant (t=-1.99,2.09,-3.07, P<0.05 or 0.01). Perceived barriers in diabetic peritoneal dialysis patients was positively correlated with edematous level (r=0.16,P<0.05) and perceived capacity balancing was negatively correlated with edematous level (r=-0.25,P<0.05). Regression analysis showed that marital status,dialysis age,daily water intake and perceived barriers were the main factors influencing fluid control in diabetic peritoneal dialysis patients. Conclusions Fluid control in diabetic peritoneal dialysis patients is affected by their health beliefs, this indicates that diabetic peritoneal dialysis patients must have insufficient awareness of fluid status and fluid adherence. It is suggested that they should establish comprehensive health beliefs.

Mycobacterium (M.) vaccae is a fast-growing species of saprophytic bacteria that is widely distributed. To understand the host immune responses induced by M. vaccae isolated from bovine submaxillary lymph nodes, C57BL/6 mice were infected with reference strain M. vaccae Bacillus Calmette-Guérin (BCG) and isolated M. vaccae using intraperitoneal injections. Comparison of the bacterial replication and organ pathology between M. vaccae and M. vaccae BCG revealed that M. vaccae was more malignant than M. vaccae in mice. We also demonstrated that serum from the M. vaccae-infected mice contained a higher expression level of gamma-interferon (IFN-γ), tumor necrosis factor alpha, monocyte chemoattractant protein-1, interleukin (IL)-4, IL-12, IL-10 and transforming growth factor beta than did the other groups, especially after week 4. Furthermore, when the numbers of CD3⁺CD4⁺IFN-γ⁺ and CD3⁺CD4⁺IL4⁺ cells in the infected mice were observed by flow cytometry, we found that a powerful T helper 1 (Th1) response was induced by M. vaccae infection, which was associated with the emergence of CD3⁺CD4⁺IFN-γ⁺ cells. However, the Th1 response declined over time, which was associated with appearance of the CD4⁺CD25⁺FoxP3⁺ and CD4⁺CD25⁺CD152⁺Treg cell reaction. In addition, a strong Th2 response was found. Finally, we found that M. vaccae infection increased the production of type I IFNs, which was associated with a reduced Th1 response.
