The main reasons for moral lacking of advertisement: imperfect legal system of medical advertisement, indifferent ethical consciousness of medical advertisement, insufficient social supervision of medical advertisement. Therefore, we should perfect the legislation, establish the correct advertising moral concept, improve the quality of advertising employees, and realize the function of social supervision fully.

ObjectiveTo observe the effect of parathyroid hormone on expression of matrix GLA protein (MGP) in ovariectomized SD rats and primary osteoblast,and to study the role of MGP on the possible mechanism of postmenopausal osteoporosis.MethodsThirty-six Sprague-Dawley female rats were allocated into 3 groups,12 in each:sham operation group,ovariectomized group( OVX group),ovariectomized and parathyroid hormone treatment group.Animals in the parathyroid hormone group were injected parathyroid hormone (20 μg/kg,three times a week for 12 weeks) three weeks after ovariectomy.All rats were sacrificed after 18 weeks.Urine and serum were collected every three weeks.Lumbar vertebral bones were observed by immunohistochemistry.Bone mineral density (BMD) of lumbar vertebra of rats was determined.The content of MGP in serum and urine was determined by enzyme-linked immunosorbent assay (ELISA).Expression of undercarboxylated Matrix GLA Protein (ucMGP) was detected by immunochistochemistry.Relative quantification of MGP mRNA expression in lumbar vertebra bone was detected by Fluorescent real-time quantitative polymerause chain reaction.Results ( 1 ) 18 weeks after ovariectomy,BMD of lumbar vertebra in OVX group was lower than those in sham group and parathyroid hormone group significantly ( P＜0.05 ).(2) The content of MGP in serum and urine was dynamic variation after treatment hy parathyroid hormone,and it was significant compared with OVX group ( P＜0.05 ).( 3 ) Immunohistochemical localization of ucMGP was seen in lumbar vertebra in OVX group.(4) Relative quantification of MGP mRNA expression in lumbar vertebra in OVX group was increased significantly compared with other groups ( P＜0.01 ).( 5 ) parathyroid hormone ( 1-34 ) in 10-7mol/L,10-8mol/L,10-9 mol/L up-regulated MGP mRNA expression in primary osteoblasts about 6.78,5.31,and 2.23 times than control respectively.It was in a dose-dependent manner.ConclusionThe effect of parathyroid hormone on the expression of matrix gla protein may play an important role in mechanism of postmenopausal osteoporosis

Objective To investigate the incidence of atherosclerotic renal artery stenosis (ARAS), the relationship between ARAS and cerebral artery stenosis, and the risk of ARAS in patients with brain infarction. Methods The clinical data of 1 650 brain infarction patients were analyzed, which were carried out digital subtraction angiography(DSA) of cerebral and renal artery.The incidence of ARAS was counted out, and the relationship was analyzed between the different degree and number of cerebral artery stenosis and the rate of RAS. The demographic characteristics and the common risk factors of atherosclerosis were recorded, and the risk factors of ARAS were analyzed. Results The rate of ARAS in moderate stenosis group and severe stenosis and occlusion group of cerebral artery were all significantly higher than that in mild stenosis group and no stenosis group (all P < 0.01). The rates of ARAS in severe stenosis and occlusion group were significantly significantly higher than those in moderate stenosis group (P < 0.01). The rates of ARAS in 2 branch stenosis group and ≥3 branch stenosis group were both significantly higher than those in no stenosis group and 1 branch stenosis group (P < 0.01). The rates of ARAS of ≥3 branch stenosis group were significantly higher than those in 2 branch stenosis group (P<0.05). The rate of ARAS of 1 branch stenosis group were significantly higher than those in no stenosis group (P < 0.05). Age, hypertension, moderate or more artery stenosis or occlusion, and≥2 branch stenosis was independent risk factor of ARAS. Conclusions The incidence of ARAS increasesd with the increase of the degree of cerebral artery stenosis and the number of branch involved.Older age, hypertension, moderate or more artery stenosis or occlusion, and≥2 branch stenosis is risk factor for ARAS.

Objective To determine the prevalence of diabetes mellitus and related risk factors among residents in the urban and rural area of Chengdu.Methods A cluster sampling was used to establish a study population of inhabitants aged 30 to 70.Totally,1 847 participants were enrolled in this study.Questionnaire including general information and dietary information in the past year was used to collect related data.Height,body weight and oral glucose tolerance test (OGTT) were measured.Factor analysis was used to analyze the dietary pattern while multivariate unconditional logistic regression used for risk factors in total population,urban and rural residents,respectively.Results The population standardized prevalence rates of diabetes in the overall,urban and rural residents were 20.2％,28.7％,11.1％,respectively.Among total population,middle-aged (OR=2.337,95％CI:1.305-4.185) and the elderly (OR=5.990,95％ CI:3.389-10.586) residents had higher diabetes risk than the younger ones.Administrators (OR=1.434,95％ CI:1.000-2.057) and ordinary clerks (OR=2.870,95％ CI:1.653-4.980) were more vulnerable to diabetes than peasants.Similarly,middle-aged (OR=2.973,95％ CI:1.101-8.031) and elderly (OR=5.972,95％ CI:2.267-15.730) turned out to be more predisposed than young people in the urban area.Compared with peasants,ordinary clerks (OR=2.196,95％CI:1.213-3.975) seemed to be more liable to diabetes.In the mral areas,dietary pattern with higher energy and protein (OR=1.404,95％ CI:1.113-1.772) could be subject to diabetes.Conclusion The prevalence of diabetes in Chengdu was relatively high.Age,career and dietary pattern are mainly risk factors.The factors in different districts are vaious.Intervention on nutrition should be different,area-wise.

Objective:To explore the effect of communication competence and psychological resilience on job burnout among Operating Room nurses.Methods:From March to June 2023, randomized clustering sampling was used to select 138 registered Operating Room nurses from four ClassⅢ Grade A hospitals in Taizhou for investigation. The survey was conducted using the general information questionnaire, Operating Room Nurses' Job Stressor Scale, Chinese version of the Connor-Davidson Resilience Scale, Nurses' Clinic Communication Competence Scale, and Maslach Burnout Inventory-General Survey. Hierarchical linear regression analysis was used to explore the effects of communication competence and psychological resilience on job burnout among Operating Room nurses.Results:A total of 138 questionnaires were sent out, and 133 valid questionnaires were collected, with a valid response rate of 96.38% (133/138). Among 133 Operating Room nurses, the job burnout score was (56.35±9.28), and the communication competence, psychological resilience, and work stress scale scores were (196.71±18.92), (78.09±18.31), and (96.37±22.47), respectively. Pearson correlation showed that job burnout among Operating Room nurses was negatively correlated with psychological resilience ( r=-0.475, P<0.01) and communication competence ( r=-0.241, P<0.01), and positively correlated with work stress ( r=0.360, P<0.01). Hierarchical linear regression analysis showed that, after controlling for other variables, psychological resilience and communication competence were the influencing factors of job burnout among Operating Room nurses ( P<0.01), which could explain 17.70% of the variation. Conclusions:The level of job burnout among Operating Room nurses is relatively high, and psychological resilience and communication competence are independent influencing factors. Managers can provide psychological counseling and support services for Operating Room nurses, offer communication competence training programs, and prevent and reduce job burnout among Operating Room nurses.

Objective To investigate the role of STAT3 transcription factor in IL-6 inducing epithelial mesenchymal transition (EMT) of human peritoneal mesothelial cells (HPMCs).Methods HPMCs were cultured in vitro and grouped.(1) According to the stimulation time with 50 μg/L IL-6,HPMCs were divided into 24,48,72 h groups.(2) HPMCs were grouped 50,100 μg/L according to IL-6 concentration.(3) HPMCs were respectively divided into control group,IL-6 group,empty vector group,empty vector+IL-6 group,virus infecting group and virus infecting+IL-6 group,as lenti-virus vector mediating RNA interference targeting STAT3 was applied.The mRNA expressions of E-cadherin,α-smooth muscle actin (α-SMA) and vascular endothelial growth factor (VEGF) were detected by real time PCR;their protein expressions and the phosphorylation of JAK2 and STAT3 were detected by Western blotting;the expressions and distribution of E-cadherin and α-SMA were observed by immunofluorescence.Results Compared with those in control group,the expression of E-cadherin decreased remarkably (P ＜ 0.05),while the expressions of VEGF and α-SMA and the ratio of phosphorylated (p)-JAK2/JAK2 and p-STAT3/STAT3 increased significantly in IL-6 concentration groups and stimulation time groups (all P ＜ 0.05),which had been dose and time dependent.Compared with empty vector+IL-6 group,virus infecting+IL-6 group had decreased expressions of VEGF and α-SMA,while increased expressions of E-cadherin (all P ＜ 0.05).Conclusions IL-6 can promote VEGF and α-SMA gene expression and prevent E-cadherin gene expression by STAT3,which involves in EMT of peritoneum fibrosis.While STAT3 gene is knocked-down,EMT is inhibited in HPMCs.

Objective To investigate the incidence situation of metabolic syndrome (MS) in patients with continuous ambulatory peritoneal dialysis (CAPD),and analyze the correlation between MS and prognosis of patients.Methods The patients who received peritoneal dialysis from June 1,2002 to April 30,2018 and followed up regularly were divided into MS group and non-MS group according to the diagnostic criteria of MS.Follow-up was until July 31,2018.The differences of clinical data,metabolic indexes and clinical outcomes between the two groups were compared.The survival rates of the two groups were compared by Kaplan-Meier survival curve,and the risk factors of all-cause death and cardiovascular disease (CVD) death were analyzed by Cox regression analysis.Results A total of 516 patients with CAPD were enrolled in this study,including 340 males (65.9％)and 176 females (34.1％).Their age was (47.29± 12.20) years.The median follow-up time was 20 (9,39) months.According to the diagnostic criteria of MS,the patients were divided into MS group (210 cases,40.7％) and non-MS group (306 cases,59.3％).At baseline,there was no significant difference in age,educational background,duration of peritoneal dialysis,smoking history and drinking history between the two groups (P ＞ 0.05),but the patients in MS group were more exposed to high glucose peritoneal dialysate (P ＜ 0.05).The body mass index (BMI),blood phosphorus,blood glucose,blood potassium,triglyceride,cholesterol and systolic blood pressure in MS group were significantly higher than those in non-MS group (all P ＜ 0.05),and HDL-C level was significantly lower in MS group than in non-MS group (P ＜ 0.05).There were no significant differences in other indicators between the two groups (P ＞ 0.05).Kaplan-Meier survival curve showed that the cumulative survival rate in MS group was significantly lower than that in non-MS group,and the difference was statistically significant (Log-rank x2=14.87,P ＜ 0.001).If CVD death was taken as the end event,the cumulative survival rate in the non-MS group was significantly higher than that in the MS group (Log-rank x2=14.49,P ＜ 0.001).Multivariate Cox regression analysis showed that MS and high 4 h dialysate creatinine/serum creatinine ratio (4hD/Pcr) were independent risk factor for all-cause death (HR=1.982,95％CI 1.240-3.168,P=0.004;HR=3.855,95％CI 1.306-11.381,P=0.015) and CVD death (HR=2.499,95％CI 1.444-4.324,P=0.001;HR=5.799,95％ CI 1.658-20.278,P=0.006) in patients with CAPD.Conclusion The prevalence of MS in patients with CAPD is high,and MS and high 4hD/Pcr are independent risk factor for all-cause and CVD death in CAPD patients.They can be used as valuable indicators to predict the treatment outcomes and long-term prognosis of patients with CAPD.

Objective:To evaluate the efficacy and mechanism of continuous blood purification(CBP) in the treatment of severe sepsis in children.Methods:A total of 42 patients with severe sepsis were enrolled in the study.According to the parents undefined desire to treatment, on the basis of the same treatment condition, 30 cases in the blood purification group were treated with CBP, and 12 cases in the control group were given the routine treatment without CBP treatment.The difference of each index between the two groups at the baseline(before treatment) and 72 hours after treatment were observed.Results:The differences of heart rate, mean arterial pressure and brain natriuretic peptide before and after treatment in the blood purification group were significantly higher than those in control group( P<0.05), and the differences of oxygenation index, 24-hour average urine volume, blood urea nitrogen, creatinine and Glasgow coma score in the blood purification group were significantly higher than those in control group( P<0.05). The difference of capillary refill time, lactic acid and central venous oxygen saturation in blood purification group were significantly higher than those in control group( P<0.05). The level of white blood cell count, C-reactive protein, procalcitonin and interleukin-6 in blood purification group were significantly higher than those in control group, with all significant difference( P<0.05). There was significant difference in critical illness score between two groups after treatment and before treatment.The mortality rate of the blood purification group was significantly lower than that in control group( P<0.01). Conclusion:CBP can improve cardiovascular function, brain function, renal function, tissue perfusion, inflammation index, internal environment, and improve the score of children with severe sepsis.

Objective:To analyze clinical factors related to nosocomial infection in children with extracorporeal membrane oxygenation(ECMO)support.Methods:General data, infection data and relevant factors in children with ECMO support in Bayi Children′s Hospital, the 7 th Medical Center of People′s Liberation Army General Hospital and Henan Provincial People′s Hospital from September 2012 to February 2020 were reviewed.Relevant factors of nosocomial infection in them were analyzed. Results:Among 163 cases, 36(22.1%) children supported with ECMO had infections during the period of ECMO, and 72 pathogenic microorganisms were detected, including 67 bacteria (33 Acinetobacter baumannii, 21 Klebsiella pneumoniae, and 6 Pseudomonas aeruginosa) and 5 fungi.Pathogens from the respiratory system, blood system, urinary tract and abdominal cavity were detected in 45 cases(62.5%), 25 cases (34.7%), 1 case (1.4%), and 1 case (1.4%), respectively.Drug sensitivity analysis of the Acinetobacter baumannii showed that it was the extensively resistant strain.Compared with uninfected children supported with ECMO, ECMO support time[(10.0±6.7) d], hospitalization[(34.0±25.3) d], hospitalization cost[(234 368±113 234) yuan], preoperative oxygenation index(52.8±23.0) and lactate value[(9.6±5.9) mmol/L]were significantly higher in nosocomial infection ones[(4.6±3.2) d, (24.3±19.8) d, (161 416±65 847) yuan, 35.6±10.4, (5.6±5.4) mmol/L] supported with ECMO (all P<0.05). There was no significant difference in the mortality between 2 groups ( P>0.05). In addition, lactate level (9.8 mmol/L) and oxygenation index (36.0±12.7) were significantly higher in died children(2.7 mmol/L, 22.1±10.4) with nosocomial infection during the period of ECMO support than those of survivors (all P<0.05). Multivariate Logistic regression analysis showed that ECMO support time( OR=7.054, 95% CI: 2.206-25.525) and preoperative lactate value( OR=2.250, 95% CI: 1.378-4.611) were independent risk factors of nosocomial infection. Conclusions:Correcting underlying diseases of ECMO supporting and shortening the duration of ECMO can reduce the incidence and mortality of nosocomial infection in children who are supported with ECMO.

Objective:To understand the symptoms of diarrhea of residents in Tianjin and their willingness to vaccinate, to provide reference for health education, prevention and control of infectious diarrhea.Methods:Cross-sectional study design was adopted. From September to December 2023, a questionnaire survey was conducted among some residents as subjects in Nankai District, Beichen District, Baodi District and Binhai Area of Tianjin by multistage stratified cluster random sampling,to collect information such as sociodemographic characteristics, diarrhea symptoms and vaccination intention. According to the formula n=[ u2απ (1 - π)]/ δ2, the estimated sample size was 3 458 cases. The logistic regression model was used to analyze the factors related to the willingness of the respondents to receive diarrhea vaccination. The software SPSS 24.0 was used for statistical analysis. Results:A total of 3 808 subjects were investigated, with the male-to-female ratio as 1∶1.11 (1 806∶2 002), the age was (42.48±21.59) years old, and the education level of middle school or below accounted for 50.84% (1 936/3 808). The incidence rate of diarrhea was 18.28% (696/3 808), and 48.84% (1 860/3 808) were willing to be vaccinated with diarrhea vaccine. The results of multivariate logistic regression analysis showed that the age was 15-59 years old and ≥60 years old (a OR=2.31, 95% CI:1.80-2.96; a OR=1.66, 95% CI:1.38-2.00), lived in Binhai Area (a OR=2.09, 95% CI:1.62-2.71), and those who knew that community health service centers can provide the vaccination (a OR=1.61,95% CI:1.34-1.92), those who walked from the address to the community health service center were less than 15 minutes (a OR=1.54, 95% CI:1.28-1.85), those who often travel or on business (a OR=1.36, 95% CI:1.07-1.73), and those who actively obtained health care information related to diarrhea prevention when going abroad (a OR=1.69,95% CI:1.43-1.98) were more willing to be vaccinated against diarrhea. Conclusions:The incidence of diarrhea symptoms of residents was slightly higher in Tianjin, but they were less willing to be vaccinated against diarrhea. People who often go outside and go abroad were more willing to be vaccinated against diarrhea. It is suggested that the popular science propaganda and health education of diarrhea vaccine should be effectively carried out by using network platform in community.
