ObjectiveTo investigate the effect of Dingzhi Xiaowan （DZXW） in post-stroke cognitive impairment （PSCI） model mice. MethodsThe cerebral ischemia-reperfusion injury model of mice was established by using the middle cerebral artery occlusion method. Forty C57BL/6 male mice were randomly divided into the sham operation group， model group， low-dose DZXW group （1.43 g·kg^-1）， and high-dose DZXW group （2.56 g·kg^-1）， with 10 mice in each group. Both the sham operation group and the model group were treated with equal amounts of normal saline by gavage， and the above four groups of mice were gavaged once a day for 30 consecutive days. Morris water maze test was used to evaluate the learning memory ability of mice. Serum levels of amyloid precursor protein （APP）， amyloid 42 （Aβ₄₂）， acetylcholinesterase （AChE）， and superoxide dismutase （SOD） were measured by enzyme-linked immunosorbent assay （ELISA）. Deoxyribonucleotide end transferase-mediated nick end labelling （TUNEL） assay was applied to detect the degree of apoptosis in the mouse's hippocampal neurons. Western blot was used to detect the protein expression of phosphoinositol-3 kinase （PI3K）， protein kinase B （Akt）， mammalian target of rapamycin （mTOR）， hypoxia-inducible factor 1-alpha （HIF-1α）， B-cell lymphoma 2 （Bcl-2） homologous structural domain protein （Beclin1）， sequestosome 1 （p62）， microtubule-associated protein light chain 3 （LC3）， Bcl-2， and Bcl-2-associated X protein （Bax） in hippocampal tissue. Prussian blue staining was used to detect iron deposition in hippocampal tissue. Transmission electron microscopy was taken to observe the ultrastructure of the mouse's hippocampal neurons. ResultsCompared with the sham operation group， the latency， APP， Aβ₄₂， AChE， TUNEL positivity， ferric ion deposition， HIF-1α， Beclin1， Bax， and LC3Ⅱ/Ⅰ were significantly increased in the model group （P<0.01）， while the number of crossing platforms， SOD， p-PI3K， p-Akt， p-mTOR， p62， and Bcl-2 were significantly decreased （P<0.01）. Compared with the model group， the latency， APP， Aβ₄₂， AChE， TUNEL positivity rate， ferric ion deposition， HIF-1α， Beclin1， Bax， and LC3Ⅱ/Ⅰ were significantly reduced in the DZXW groups （P<0.05）， while the number of crossing platforms， SOD， p-PI3K， p-Akt， p-mTOR， p62， and Bcl-2 were significantly higher （P<0.05）. ConclusionDZXW can alleviate cognitive impairment induced by oxidative stress-aggravated hippocampal neuronal damage in PSCI model mice by modulating the PI3K/Akt/mTOR/HIF-1α autophagy signalling pathway.

Objective:To systematically evaluate the effects of insulin combined with metformin in the treatment of gestational diabetes mellitus(GDM)on maternal and neonatal outcomes in China,in order to provide evidence-based medical recommendations for clinical treatment.Methods:The Chinese Academic Database(CNKI),VIP Database,and Wanfang Database were searched from the establishment of the database to April 2022 for randomized controlled trials(RCTs)of insulin combined with metformin versus insulin alone in the treatment of GDM to observe the adverse outcomes for neonates.The Cochrane Collaboration was used for quality evaluation and Review Manager 5.4 software was utilized for meta-analysis.Results:A total of 51 studies were included in the meta-analysis,including 4 916 GDM patients,with 2 460 cases in the combined treatment group and 2 456 cases in insulin alone group.The meta-analysis results revealed significant reductions in rates of cesarean section(OR=0.32,95%CI:0.26-0.39),preterm birth(OR=0.26,95%CI:0.20-0.34),polyhydramnios(OR=0.27,95%CI:0.20-0.36),gestational hypertension(OR=0.25,95%CI:0.18-0.35),neonatal jaundice(OR=0.25,95%CI:0.19-0.32),neonatal hypoglycemia(OR=0.33,95%CI:0.25-0.45),macrosomia(OR=0.23,95%CI:0.17-0.30),and neonatal respiratory distress(OR=0.23,95%CI:0.16-0.34)in the combined treatment group than those in the control group(P＜0.01).Conclusions:For patients with GDM,insulin combined with metformin is significantly more effective than insulin alone in reducing the incidence of maternal and neonatal complications.This combination therapy results in improved outcomes for both mothers and infants.

Objective:To explore the effects of WeChat-based health education on management of hypertensive outpatients under medical consortium.Methods:Totally 180 hypertensive patients who attended the Multidisciplinary Clinics of Beijing Anzhen Hospital, Capital Medical University, and Datun Community Health Service Center from communities under our medical consortium from November 2018 to April 2019 were selected and divided into the observation group ( n=91) and the control group ( n=89) according to the visit time. Patients in the control group received routine health education, while patients in the observation group received WeChat-based health education under medical consortium for 6 months. The self-management ability (using Hypertension Patients Behavior Rating Scale, HPSMBRS) , treatment compliance (using Therapeutic Adherence Scale for Hypertensive Patients, TASHP) , the 24 h average systolic and diastolic blood pressure, the average systolic and diastolic blood pressure at daytime, and the average systolic blood pressure and diastolic blood pressure at night were compared between the two groups. Results:After the intervention, the diet management, medication management, disease monitoring, exercise management, work and rest and emotional management scores of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the medication-taking behavior, bad medication-taking behavior, daily activity management behavior and tobacco and alcohol addiction scores were higher than those of the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the 24 h average systolic and diastolic blood pressure, average systolic and diastolic blood pressure at daytime and average systolic and diastolic blood pressure at night decreased in the observation group, and the differences were statistically significant compared with the control group ( P<0.05) . Conclusions:The WeChat platform under medical consortium provides standardized, consistent, continuous and effective health education, which can improve the self-management ability and treatment compliance of hypertensive outpatients, and can effectively control blood pressure levels. It shows sound effects in clinical use.

Objective To explore the relationship between brachial ankle pulse wave velocity (BaPWV) change and carotid artery plaque formation in middle-aged and elderly patients with essential hypertension(EH).Methods A cross sectional study was conducted in 409 patients who were admitted in Hypertension Department in our hospital from January to September 2013.Their age ranged from 35 to 75 years,with mean aged(53.2±15.0) years.Parallel carotid artery ultrasound and BaPWV examination were performed in all patients.According to whether carotid plaques were present,patients were divided into two groups:carotid plaque group and control group.And carotid plaque group was sub-grouped into normal BaPWV group (BaPWV ＜ 1400cm/s) and increased BaPWV group(BaPWV≥1400 cm/s) according to BaPWV levels.The detection rate of carotid plaque was compared between normal BaPWV group and increased BaPWV group.The correlation between BaPWV and carotid plaques was analyzed by multivariate logistic regression analysis.Results Compared with the control group,carotid plaque group showed the prevalence of carotid plaques was increased along with the increases of age(t=11.0,P=11.0),systolic blood pressure (t=3.87,P=3.87),diastolic blood pressure(t=3.70,P=0.00),pulse pressure(t=6.13,P 6.13),total cholesterol levels(t=2.57,P=0.01).The detection rate of carotid plaque was higher in increased BaPWV group than in normal BaPWV group [62.6％(159/254) vs.43.2％(67/155),x2=14.61,P=0.00].After adjusting for age,blood pressure and other cardiovascular risk factors,the multivariate logistic regression analysis showed that increased BaPWV was an independent risk factor for carotid plaques(OR=2.06,P=0.05),and age,smoking,systolic pressure,diastolic pressure,pulse pressure,total cholesterol,low-density lipoprotein cholesterol,triglyceride levels were positively correlated with carotid plaques.Conclusions BaPWV is one of the independent impact factors for carotid plaques,which plays an important role in early diagnosis and screening for subclinical vascular lesions.

Objective To investigate the prevalence of target organ damage and analyze etiology in elderly hospitalized patients with hypertension.Methods A total of 1270 elderly inpatients aged 60 to 91 years from 2008 to 2012 were enrolled.This retrospective study was performed to analyze the etiology and the prevalence of target organ damage in hospitalized hypertensive patients.Results Among elderly hypertensive patients,secondary hypertension accounted for 14.2 ％ (180/1 270) while essential hypertension accounted for 85.8％ (1 090/1 270).In secondary hypertension,renovascular hypertension of atherosclerosis (67.8％) and primary aldosteronism (23.3％) had the higher prevalence rate.Among 1 090 hospitalized patients with essential hypertension,the prevalence of patients with ≥ 1 complications was 88.3 ％.The prevalence of cerebrovascular disease,coronary heart disease and chronic renal failure were 30.2 ％,26.7 ％ and 10.5 ％,respectively.The occurrence rate of the increased carotid intima-media thickness and left type hypertrophy were 66.6 ％ and 24.0 ％,respectively.The prevalence rate of cerebrovascular disease,coronary artery disease and chronic renal failure were increased with aging (P＜0.05).Compared with female,male patients had a higher prevalence rate of chronic renal failure (P＜0.05).Conclusions Secondary hypertension is mainly renovascular hypertension and primary aldosteronism in elderly patients with hypertension.And damage of target organ in elderly patients with primary hypertension is more common,highest with cerebral apoplexy among three target organs such as heart,brain and kidney disease.

PURPOSE: To assess the compliance of Chinese urologists with China's benign prostatic hyperplasia (BPH) clinical practice guideline and to explore the diagnosis and therapy modalities for geriatric patients with BPH. METHODS: A cross-sectional survey study was carried out in 33 medical centers in 11 different cities in China. A total of 190 urologists participated in a survey to record their preferences for diagnostic tests and treatment options for BPH outpatients. Diagnostic test results as well as health care demands were collected by surveying 2,027 outpatients aged 60 years and older. RESULTS: The survey response rate was 97.4%. The respondents generally used the diagnostic tests recommended in China's BPH clinical practice guideline at varying rates. The used rates for medical history, ultrasonography, and urinalysis were above 90.0%; that for uroflowmetry was 31.2%. In addition, the rate of use of recommended tests was higher among doctors in the north than among those in the south. Combination therapy with alpha-adrenoceptor antagonists and 5alpha-reductase inhibitors was the preferred treatment option for BPH, and was increasingly used with worsening lower urinary tract symptoms. Finasteride was the most prescribed medication (48.0%), followed by tamsulosin (22.7%). CONCLUSIONS: This study assessed the preferences of urologists in the diagnosis and treatment of BPH, which will serve as an important reference for updating and improving China's current BPH clinical practice guideline.

OBJECTIVE: To explore the knowledge of, attitude to and practice in nutrition and food safety, the influence factors, and to provide reference for relevant health education programs. METHODS: A total of 510 randomly selected students from Grade 1 to 3 randomly selected were surveyed by a nutrition and food safety questionnaire in Huize of Yunnan Province and Zhen'an of Shaanxi Province. Multiple-linear regression was used to analyze the influence factors of nutrition and food safety. RESULTS: The correct answer rate on nutrition and food safety knowledge of the pupils from Grade 1 to 3 was 74.4%. Nutrition and food safety knowledge score was 11.16±2.51, but only 7.8% of the students correctly answered "How much water should we drink every day". Students who agreed that it is necessary to learn nutrition and food safety knowledge in school accounted for 78.6% and 73.9%, respectively. At least half of the students showed correct behaviors in 7 aspects. The students who ate beans and meat daily or regularly accounted for 28.4% and 34.9%, but only 9.2% of the students drank more than 7 cups of water daily. The multiple-linear regression showed that the major influence factors were the area, grade, status of lodge and singleton. CONCLUSION Education is needed for students to form better dietary habits, especially those in low grades, non-singleton, and in board schools.

OBJECTIVE: To determine the immune-protective effect of Japan Schistosoma (Chinese mainland strain) 23 kD membrane protein-heat shock protein (SjC23-Hsp70) DNA vaccine plus adjuvantinduced interleukin-12 (IL-12) plasmid DNA on Schistosoma japonicum infection in water buffalos. METHODS: Forty-five health water buffalos (8-10 months old) in non-endemic area of schistosomiasis were randomly assigned into group A (SjC23-Hsp70+IL-12, 300 μg), group B (SjC23+IL-12, 300 μg) and group C (pVAX+IL-12, 300 μg), 15 in each group. Each buffalo was immuned by shoulder intramuscular injection for 3 times, at an interval of 28 days. Twenty-eight days after the last immunization, each buffalo was infected with 1000 Japan cercariae of Schistosoma. Fecal examinations were conducted 2 days and 1 day before the perfusion, and on the day of perfusion. The number of hatching miracidia and eggs per gram feces was recorded. Fifty-six days after the infection, the buffalos were sacrificed and perfused via the descending aorta. The recovered adult worms and eggs in the liver tissue were counted. RESULTS: We compared group A and B with group C: the estrogen reduction rate was 45.7% and 26.61%; bug reduction rate was 44.51% and 25.84%; the fecal egg reduction rate was 41.1% and 31.63%; the miracidium reduction rate was 48.11% and 38.07%; and the liver egg reduction rate was 43.39% and 31.95%. The above rates in group A were higher than those in group B (P<0.05). CONCLUSION SjC23-Hsp70 DNA vaccine combined with IL-12 may have a significant immunoprotective effect on buffalos.

To analyze the relationship among ambulatory blood pressure (AMBP), ankle brachial index (ABI) and left ventricular mass index (LVMI) in hypertensive patients. Methods 578 hypertensive inpatients were reviewed. Results The general clinical dataof selected patients, their ABI, LVMI were not different significantly between male and female. The correlation analysis showed that LVMI was positively correlated with the 24-hour average systolic (r=0.245, P=0.000) or diastolic (r=0.158, P=0.000) blood pressure, whereas negatively correlated with percent of systolic (r=－0.104, P=0.012) or diastolic (r=－0.132, P=0.001) blood pressure declining at night. No significant correlation was found between LVMI and BMI. Multiple regression analysis revealed that LVMI was significant independently positive correlated with 24-hour average systolic blood pressure (P=0.000). Conclusion LVMI does not correlate with ABI, but independent positive related with 24-hour average systolic blood pressure.
