Objectives To explore the effect of transient continuous subcutaneous insulin infusion (CSII) on β cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetic patients and its potential mechanism. Methods Ten patients with newly diagnosed type 2 diabetes mellitus (T2DM) accepted CSII for two weeks. Intravenous glucose tolerance test (IVGTT) and hyperinsulinemia euglycemia clamp test were performed before and after CSII. Serum soluble E-selectin (sE-selectin) was used to evaluate the injury of vascular endothelial cell, while serum high sensitivity C reactive protein (hsCRP) and soluble CD_(14) (sCD_(14)) were both used to assess inflammatory condition. Results (1) Compared with those before treatment, the blood glucose levels of IVGTT, the area under the curve of the blood glucose, glycosylated hemoglobin, TC and LDL-C in the patients were decreased after CSII (P < 0. 05 or 0. 01). (2) Compared with those before treatment, the insulin levels of IVGTT (except the fasting insulin), the area under the curve of insulin and acute insulin response were all increased after CSII(P < 0.05 or 0.01). (3) Compared with that before treatment, the glucose infusion ratio in the clamp test [(3.46±1.66)mg·kg~(-1)·min~(-1) increased to (7.14±2.37)mg·kg~(-1)·min~(-1)]and HOMA-β elevated, while HOMA-IR declined (P <0. 05 or 0. 01 in all). (4) Compared with those before treatment, the levels of serum sE-selectin, sCD_(14) and hsCRP were decreased (P < 0. 01, except for hsCRP) . Conclusion Transient intensive insulin therapy in patients with newly diagnosed T2DM is useful to restore 13 cell function, attenuate insulin resistance, repair vascular endothelial injury and improve the disorder of blood sugar and lipid. The mechanism may be related with the inhibition of inflammation in patients.

Objective:To evaluate the effect of health science popularization in child caregivers by using social media of WeChat and Weibo in China in 2020.Methods:A questionnaire was designed based on the knowledge of children health from January to March 2020, and the public were invited to participate in the survey by visiting the official accounts of WeChat and Weibo of China CDC to analyze the awareness of health related knowledge and the change of daily behaviors in the child caregivers.Results:In the 1 325 child caregivers included in this survey, the awareness rate of chronic disease reexamine was lowest (74.94%), and the awareness rate of quality-oriented education was highest (99.55%). In the 7 questions in the questionnaire, the correct answer rate of the question about the reexamine of chronic disease was <75.00% (below the standard), the correct answer rate to other six questions were all ≥75.00% (above the standard). Logistic regression analysis showed that the education levels of senior high school or technical secondary school, junior college, bachelor's degree, master's degree or above, being worker, business/service personnel, teacher and company employee were the influencing factors for the awareness of the chronic disease related knowledge in child caregivers (all P<0.05). The daily behaviors of child caregivers after acquiring health knowledge were significantly improved (all P<0.001). Conclusions:In the season with high incidence of respiratory diseases, the use of new media platforms, such as WeChat and Weibo, to conduct health education had a good performance, resulting in higher rate of knowledge about healthy parenting and a significant improvement in daily behaviors in child caregivers. The results showed that the health education about the reexamine of chronic diseases in children should be focused on child caregivers with low education level, especially workers, business/service personnel.

Objective:To understand the cognition on and status quo of influenza vaccination among all age groups in the survey areas from 6 provinces so as to explore the main factors related to influenza vaccination.Methods:A cross-sectional survey method was conducted to study the knowledge on influenza prevention and control, as well as on the status of influenza vaccination in Beijing, Inner Mongolia, Shanghai, Guangdong, Yunnan, and Gansu provinces through 12320 health hotline telephone with method of random number table in Mar-May 2018. The survey sample size was 9 438 respondents.Results:The survey response rate was 46.4 %(10 045/21 658). A total of 10 045 respondents were surveyed. The awareness on flu-related knowledge "influenza is different from the common cold" was 75.3 % (7 564/10 045), rate on "influenza virus will cause serious consequences" was 82.0 % (8 241/10 045). The rate of health behavior such as frequent hand, washing hand, wearing masks and isolating themselves were 80.41 % (7 936/9 873), 75.8 % (7 506/9 899) and 73.6 %(7 228/9 822) respectively when the influenza-like symptoms already started. The influenza vaccination rate in the past year was only 5.7 % (570/10 037). Multivariate logistic analysis of influenza vaccination rate in the past year showed that respondents who were from Gansu province or Beijing, respondents occupations were as medical staff or full-time students, respondents who were living with more than 2 people at the same house, respondents who had had influenza symptoms without wearing masks, the influenza vaccination rates were higher in the past year. Conclusions:Rates regarding the awareness of influenza-related knowledge, health behavior when the influenza-related symptoms already started and having received the influenza vaccine vaccination in the past year should be further improved in the six provinces. Health education on influenza-related knowledge and vaccine vaccination should be strengthened, strategies including free vaccination are bound to be explored.

Objective To explore the correlation between functional striatal abnormalities(FSA)scores and symptoms and cognitive function in patients with schizophrenia.Methods A total of 92 patients with schizophrenia admitted to the Second Affiliated Hospital of Xinxiang Medical University from July 2021 to February 2022 were selected as the research subjects,15 patients were excluded due to excessive interference with head movement during image data analysis,and 77 patients were finally included in the statistical analysis.The cognitive function of the patients before treatment and after 8 weeks of treatment was evaluated through a set of cognitive function tests.The severity of symptoms before treatment and after 8 weeks of treatment was evaluated according to the positive and negative symptom scale(PANSS).The patients were divided into the ineffective group(PANSS＜50％,n=33)and the effective group(PANSS ≥ 50％,n=44)according to the PANSS reduction rate.Before treatment and 8 weeks after treatment,the resting-state functional magnetic resonance imaging scans were performed,and FSA scores were calculated.Results There was no significant difference in FSA scores of patients between the effective group and the ineffective group before treatment(P＞0.05).After 8 weeks of treatment,the FSA scores of patients in the two groups were significantly higher than those before treatment(P＜0.05).After 8 weeks of treatment,there was no significant difference in FSA scores of patients between the effective group and the ineffective group(P＞0.05).Before treatment and after 8 weeks of treatment,there was no significant correlation between the FSA scores and the total PANSS scores,positive factor scores,negative factor scores and pathological factor scores in the two groups(P＞0.05).There was no significant corre-lation between the pre-treatment FSA scores and the differences in positive factor scores,negative factor scores and pathological factor scores before and after treatment in both groups(P＞0.05).In the effective group,the FSA score was significantly nega-tively correlated with the spatial span score(P＜0.05)and significantly positively correlated with the category fluency score(P＜0.05)before treatment;however,there was no significant correlation between the pre-treatment FSA score and the scores of trail making,symbol coding,word learning,maze solving,visuospatial memory,2-digit continuous performance,3-digit continuous performance and 4-digit continuous performance(P＞0.05).In the ineffective group,there was a significant negative correlation between the pre-treatment FSA score and the spatial span and 4-digit continuous performance scores(P＜0.05),while there was no significant correlation between the pre-treatment FSA score and the scores of trail making,symbol coding,word learning,maze solving,visuospatial memory,category fluency,2-digit continuous performance and 3-digit continuous performance(P＞0.05).There was no significant correlation between the FSA score and cognitive function scores after treat-ment in the effective group(P＞0.05).There was a significant positive correlation between the FSA score and the trail making score after treatment in the ineffective group(P＜0.05),but there was no significant correlation between the FSA score and the scores of symbol coding,word learning,spatial span,maze solving,visuospatial memory,category fluency,2-digit continuous performance,3-digit continuous performance and 4-digit continuous performance(P＞0.05).Conclusion FSA scores in patients with schizophrenia increase significantly after treatment.FSA scores may not be related to the severity of symptoms or treatment response,but are correlated with the cognitive function of information processing speed.
