Objective To explore medical institution-led exercise training interventions,prelimina-ry preventive measures,and comprehensive health service strategies for elderly adults.Methods Sixty elderly adults from communities under the jurisdiction of primary hospitals who voluntarily participated in the training and met the inclusion criteria were divided into 75 to 79 years old group and 80 to 84 years old group.Elastic bands exercise were selected as the method for physical training for elderly community members.A total of three sets(9 items)of exercise,including upper and lower limb mus-cle strength exercises and balance as well as coordination training,were designed.The training period lasted for 12 weeks,with each session lasting 1 hour,three times a week.The medical team partici-pated in training supervision and follow-up evaluations throughout the process,dynamically adjusting the training intensity based on individual needs.Results Comprehensive safety and support meas-ures significantly improved training participation and completion rates.No sports injuries or adverse events occurred throughout the process,and all participants completed the training plan.After train-ing,statistically significant differences were observed in grip strength,five-times sit-to-stand test duration,Berg Balance Scale(BBS)scores,and Timed Up and Go(TUG)test results(P＜0.05),indicating effective physical fitness improvement.Conclusion Elastic band exercises are a suitable mode for physical improvement training among elderly adults,significantly enhancing muscle strength in the limbs and trunk and improving balance function.The positive communication and in-teraction in group activities significantly boost elderly adults'confidence in healthy living,leading to notable improvements in their mental state.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.

Objective:To investigate the efficacy of liraglutide combined with enpagliflozin in the treatment of obesity complicated by type 2 diabetes mellitus.Methods:A total of 160 obesity patients with type 2 diabetes mellitus who received treatment in Yuyao People's Hospital, China between October 2018 and October 2019 were included in this study. They were randomly assigned to receive repaglinide, insulin detemir and metformin in combination (control group, n = 80) or liraglutide, enpagliflozin and metformin in combination (treatment group, n = 80). After 3 months of treatment, fasting blood glucose, glycosylated hemoglobin, 2-hour postprandial blood glucose, body mass index, tumor necrosis factor-alpha, C-reactive protein, interleukin-6, leptin, adiponectin, and vaspin as well as the incidence of adverse reactions were compared between the control and treatment groups. Results:After treatment, fasting blood glucose, glycosylated hemoglobin, 2-hour postprandial blood glucose and body mass index were reduced in each group. They were (7.89 ± 1.02) mmol/L, (8.10 ± 1.25) %, (11.10 ± 1.59) mmol/L, (23.18 ± 2.19) kg/m 2, respectively in the observation group, which were significantly lower than those in the control group [(9.88 ± 1.27) mmol/L, (11.20 ± 1.85)%, (13.67 ± 2.01) mmol/L, (27.80 ± 2.51) kg/m 2, t1 = 10.927, t2 = 12.418, t3 = 8.969, t4 = 12.405, all P < 0.001). After treatment, tumor necrosis factor-alpha, C-reactive protein and interleukin-6 levels were reduced in each group. Their levels in the observation group were [(51.19 ± 3.19) pg/L, (2.14 ± 0.31) mg/L, (4.07 ± 0.67) pg/L, respectively, which were significantly lower than those in the control group [(62.18 ± 4.10) pg/L, (3.66 ± 0.58) mg/L, (5.96 ± 0.81) pg/L, t1 = 18.922, t2 = 20.672, t3 = 8.969, all P < 0.001). After treatment, leptin and vaspin levels were reduced in each group, and their values in the observation group were (5.48±0.94) μg/L, (1.62 ± 0.37) μg/L, respectively, which were significantly lower than those in the control group [(6.59 ± 0.82) μg/L, (1.99 ± 0.52) μg/L, t1=7.959, t2=10.323, both P < 0.001]. Adiponectin level increased in each group, and it was significantly higher in the observation group than in the control group [(7.13 ± 1.52) mg/L vs. (5.12 ± 0.85) mg/L, t3 = 5.185, P < 0.001]. There was no significant difference in the incidence of adverse reactions between control and observation groups ( χ2 = 0.313, P > 0.05). Conclusion:Liraglutide combined with enpagliflozin for the treatment of obesity complicated by type 2 diabetes mellitus is highly effective. It can effectively lower blood glucose level, reduce body mass and inflammatory reactions, further regulate serum vaspin, leptin and adiponectin levels and is highly safe. Therefore, this method can be widely used in the clinic.

Objective To explore the association of fibroblast growth factor-23 (FGF23) with abdominal aortic calcification(AAC) and adverse outcomes in maintenance hemodialysis patients.Methods One hundred and fourteen cases of MHD patients were collected prospectively.Serum intact FGF23 was detected by ELISA.Abdomen lateral plain was used as a criteria to determine the abdominal aortic calcification and the abdominal aortic calcification score was counted.Logistic regression analysis was used to determine the risk factors of AAC.Kaplan-Meier analysis was applied to compare the survival rate among different groups and COX regression analysis was used to determine the association of FGF23 and mortality in MHD patients.Results Seventy-six patients present abdominal aortic calcification.The median of AACS was 4.0(0.0,11.0).The median level of FGF23 was 7277.4(2535.0,9990.8) pg/ml.The median follow-up duration was 72.0(67.8,72.8) months.During the follow-up,22 patients (19.3％) died of all-cause death and 17 cases (14.9％) died of cardiovascular diseases.Serum FGF23 level was positively correlated with AAC (r=0.285,P=0.002).Logistic regression analysis showed that longer age (OR=1.059,95％CI:1.020-1.100,P=0.003) and dialysis vintage (OR=I.009,95％CI 1.000-1.017,P=0.039),smoking history (OR=3.010,95％CI 1.177-7.696,P=0.021) and higher FGF23 level(OR=2.831,95％CI 1.010-7.937,P=0.048) were independent risk factors of moderate to severe AAC in MHD patients.Kaplan-Meier survival curves showed that the patients with AACS≥ 5 had significantly higher all-cause mortality(P=0.028) and CVD mortality (P=0.035) than those with AACS ＜ 5.However,the Kaplan-Meier analysis showed no significant difference regarding the level of serum FGF23 with the all-cause and CVD mortality.Cox regression demonstrated that FGF23 was not associated with increased mortality risk,neither in crude nor in multivariate adjusted models.Conclusions Abdominal aortic calcification had a high prevalence in MHD patients.The all-cause and CVD mortality was higher in patients with moderate to severe AAC.FGF23 was an independent risk factor of moderate to severe AAC,but it can't yet be a predictor for the allcause and CVD mortality of MHD patients.

Objective To determine the relationship between serum soluble Klotho (sKL) level and adverse outcome in maintenance hemodialysis (MHD) patients.Methods One hundred and twenty nine cases of MHD patients were collected prospectively.Serum sKL was detected by ELISA.Abdomen lateral plain was used as a criterion to determine the abdominal aortic calcification.The abdominal aortic calcification score (AAC) was calculated.Cox regression analysis was used to determine the risk factor of cardiovascular death (CVD) in MHD patients.Kaplan-Meier showed the relationship between sKL and CVD in MHD patients.Results There were 27 cases (20.9％) of allcause death and 19 cases (14.7％) of cardiovascular death.The median sKL was 612.6(379.2-816.6) nig/L,and log[iPTH] was an independent factor of sKL concentration.Low sKL had high AAC and CVD death rate.Kaplan-Meier method showed that the all-cause death rate was similar between two groups,and CVD death rate increased significantly in low sKL patients (P=0.036).Cox regression indicated that lower sKL level was associated with high CVD death rate [OR=0.352,95％CI(0.127-0.977),P=0.045].After adjustment for the general condition,biochemical indicators,the relationship still existed [OR=0.331,95％ CI (0.117-0.933),P=0.037].In no or mild vascular calcification patients (AAC ≤4),compared with high sKL patients,low sKL patients had no significant difference rate in all-cause mortality.The CVD mortality was significantly higher in high sKL (P=0.035) compared with low sKL.In severe calcification group (AAC ＞ 4),all-cause death and CVD death rates were similar between different sKL groups (P=0.991 and 0.522,respectively).Conclusions Lower sKL has the high CVD death rate and sKL level decreasing is an independent risk factor for CVD death in MHD patients.The lower sKL concentration in MHD patients with no or mild calcification may predict CVD mortality.This study suggests that sKL levels may be helpful in predicting the outcome of patients with MHD.

Objective To construct a framework and relevant evaluation items of the teaching ability for nursing teachers in colleges or universities.Methods The research was carried out by a variety of means such as theory analysis,literature study,expert consultation,etc,to explore behavior items that could be used to evaluate the teaching ability for nursing teachers in colleges or universities.A questionnaire was formed and a survey was conducted in a total of 194 nursing teachers from ten colleges or universities across the whole nation.Then,factor analysis was performed to build the relevant evaluation items for teaching ability of full-time nursing teacher.Cronbach's α and Spearman correlation were used to test the reliability and validity.Results The relevant evaluation items of teaching ability for nursing teachers contained 31 behavior items from six domains,which were teaching research ability,emotional teaching ability,expressing ability,self-examination ability,integration ability,and organizing ability.Cronbach's α of the total system was up to 0.913 0,Cronbach's α of each domain ranged from 0.681 0 to 0.815 8.Every factor had positive correlation with the totality,and the correlation coefficient of every item with its affiliated factor was greater than other factors.Conclusions The relevant evaluation questionnaire of teaching ability for nursing teachers has excellent reliability and validity.It can provide reference standard to directing admission,training,and teaching evaluation for nursing teachers.

Objective To explore the effect of HAPA theory based intervention on diet control behavior of patients with polycystic ovary syndrome (PCOS).Methods 64 obese PCOS patients were randomly divided into the intervention group and the control group,32 cases in each group.The control group received routine health education,while the patients in the intervention group received HAPA theory based intervention.The diet control behavior and clinical monitoring indexes of patients were investigated before and 1 and 6 months after intervention.Results The behavior level of the intervention group on 1 month and 6 month after intervention was significant higher than that of the control group.The levels of BMI,FT,blood glucose level two hours after OGTT,follicle number of the intervention group after intervention were significantly lower than those of the control group.Conclusions The HAPA theory based intervention can improve the diet control behavior of PCOS patients,improve the effect of clinical treatment.

Objective To explore factors affecting long-term compliance to weight management (WM) of patients with congestive heart failure (CHF)and to provide evidence for improving patients' compliance.Methods In-depth semi-structured interviews based on reinforcement theory were conducted among 18 CHF patients who received WM intervention over 6 months.The data were analyzed by Colaizzi analysis program.Results Three themes were found:precipitating factors such as the correct perception of disease and self-efficacy,the factors of positive reinforcement such as early gains from WM,readmission,follow-up,family and social support,as well as the factors of negative reinforcement such as gaining nothing during long period,physical and mental disorders.These above factors made long-term compliance to WM of 50％ of the participants dynamic and fluctuant.Conclusions Medical staff should identify patients'compliance at different stages in time during follow-up,analyze the factors that affect their compliance,and then grasp the optimal timing of intervention to perform targeted,multiform and multiple health education to improve compliance.
