Objective To explore the distribution of pathogens, bacterial drug resistance, clinical features and prognosis of bacterial meningitis (BM) in children.MethodsThe clinical data of children diagnosed with BM during January 2011 to July 2015 were retrospectively analyzed. Children were divided into good outcome group and poor outcome group by the outcome at discharge. The distribution of pathogens, bacterial drug resistance, clinical features, and prognosis were analyzed among different groups.ResultsThere were included 95 children diagnosed with BM,. among whom 69 (72.6%) children had Gram-positive bacterial infections with predominantStreptococcus pneumonia (43 cases, 45.3%) and 26 (27.4%) children had Gram-negative bacterial infections with predominantEscherichia coli (13 cases, 13.7%). More than 50%Streptococcus pneumonia andEscherichia coli were resisted to penicillin. The neurological complications in children with BM included subdural effusions, hydrocephalus, cerebral parenchyma injury, and hearing and visual impairment, et.al. Multivariate logistic regression analysis showed that consciousness, coma, and low level of glucose in cerebrospinal lfuid were the independent risk factors for adverse outcome at discharge.ConclusionStreptococcus pneumonia andEscherichia coli were the predominant pathogens in children with BM with high resistance rate to penicillin. BM children may have varying degrees of neurological sequelae. The unconsciousness and low level of glucose in cerebrospinal lfuid were associated with unfavorable outcomes at discharge.

Objective To study the impacts of alcohol dependence on the anticonvulsant effect of diazepam. Meth?ods Kunming mice (n=36) were divided into 3 groups (n=12 in each group), Alcohol Dependence Group(A group), Diaze?pam Group(D group)and Normal Saline Group(N group). A group received an intraperitoneal injection with a 0.2 mL dose of 0.8%alcohol in NS (normal saline) , while both D and N group received an injection with a 0.2 mL dose of NS without alco?hol , twice a day. Mice’s autonomic activities were monitored every day. After 7 days, the electroconvulsive experiment was performed. Both A and D group were given a weight-based dose of 0.05 mL/10 g of 0.05%diazepam via intraperitoneal injec? tion, while N group was given a 0.05 mL/10 g dose of NS. Before administration and after 15, 30, 60 min of administration, the convulsion threshold of each group was measured. Results The count of autonomic activity of mice in A group was less than that of mice in D and N group during the 2nd day to 6th day(P<0.05). On the 1st and 7th day, the difference of the count of autonomic activity of mice between A group and the other two groups was not statistically significant(P>0.05). The convulsion threshold of mice in A group was higher than that of mice in D and N group before administration(P<0.05). Af?ter administration, the convulsion threshold of mice in N group didn’t show statistically significant difference from that of mice before administration(P>0.05). After 15 min of administration, the convulsion threshold of mice in D group was high?er than that of mice in A and N group(P<0.05), while the convulsion threshold of mice in A group was higher than that of mice in N group(P<0.05). After 30 min and 60 min of administration, both the convulsion thresholds of mice in A and D group were higher than that of mice in N group(P<0.05). However, at this point, the difference of the convulsion thresholds of mice between A and D group was not statistically significant(P>0.05). Conclusion Alcohol dependence has anticon?vulsant effect. Alcohol dependence weakens the anticonvulsant effect of diazepam.

Objective To investigate the application value of amlodipine atorvastatin calcium tablet(AACT)combined with evidence-based emotional nursing mode(EENM)in elderly patients with hypertension complicated by coronary heart disease(HTN-CHD).Methods HTN-CHD patients admitted to the department of cardiology of The Second Affiliated Hospital of Wenzhou Medical University from June 2021 to June 2023 were selected retrospectively as study subjects.According to the intervention methods,the HTN-CHD patients were divided into the AACT group and the EENM group.Patients in the AACT group were given AACT combined with the usual care intervention,and the EENM group was given EENM on the basis of the AACT group.The changes of psychological status(SDS,SAS,and SPBS),adherence(medication compliance,daily exercise behavior,poor management behavior,and dietary management behavior)and blood pressure[(systolic blood pressure,SBP)and diastolic blood pressure(DBP)]were compared between two groups.The incidence of cardiovascular events in the two groups at 6 months was observed and compared.Results A total of 118 HTN-CHD patients(55 in AACT group and 63 in EENM group)were included in this study.Before the intervention,there was no significant statistical difference in the SDS,SAS,SPBS,medication compliance,daily exercise,poor management,diet management scores,SBP and DBP between AACT and EENM groups(P＞0.05).After the intervention,SDS,SAS,SPBP scores,SBP and DBP of the HTN-CHD patients significantly decreased in both AACT and EENM groups compared with before(P＜0.05).However,the medication compliance behavior score,daily exercise behavior score,bad management behavior score and diet management behavior score increased significantly compared with before(P＜0.05);SDS,SAS,SPBS scores,SBP and DBP of the patients in EENM group decreased more than those in the AACT group(P＜0.05),however,the increase of medication compliance,daily exercise,poor management and diet management behavior scores of the EENM group was higher than that in the AACT group(P＜0.05).Furthermore,the incidence of cardiovascular events was lower in the EENM group than in the AACT group(P＜0.05).Conclusion EENM combined with AACT intervention is beneficial to improve the compliance with HTN-CHD patients,improve the psychological status and blood pressure values,and reduce the incidence of cardiovascular events.

INTRODUCTION: In this study, we aimed to identify the differences in sociodemographic variables and reasons for termination of pregnancy (TOP) between married women and single/divorced women. We hope that this study can guide future policies and interventions to reduce the incidence of unsupported pregnancies in this profile group of women. METHODS: We retrospectively evaluated the sociodemographic data of 802 women who underwent an abortion for social reasons at our institution in Singapore from January 2016 to September 2018. We compared the sociodemographic variables, reasons for and methods of TOP between married and single/divorced women. RESULTS: We analysed data from 524 married women (65.3%) and 278 single/divorced women (34.7%). Married women were more likely to be of older age (29.5 years vs. 24.5 years, P < 0.001), had more living children and higher educational qualifications. The top two cited reason for abortions among married women were having enough children (42.0%) and the inability to afford another child (18.7%). Multivariate analysis showed that women aged >19 years and having more living children were independently associated with recurrent TOPs. Having a tertiary education was noted to be associated with less recurrent TOPs. CONCLUSION The most common reasons married women cited for having TOP include having enough children and the lack of financial capacity to afford another child. Recommendations to support women ought to be personalised and comprehensive in addressing their needs rather than offering a standardised support method. Greater emphasis should be placed on post-TOP family planning counselling to reduce repeated TOP.

Objective:To investigate the feasibility and clinical value of 4D flow magnetic resonance imaging (MRI) in evaluating hemodynamics of ischemic stroke patients with intracranial artery stenosis.Methods:Ischemic stroke patients with unilateral middle cerebral artery stenosis admitted from March 2017 to June 2018 in Beijing Tsinghua Changgung Hospital Stroke Center were prospectively enrolled. Time of flight magnetic resonance angiography was used to evaluate vascular stenosis, 4D flow MRI was used to measure net forward flow at the proximal of stenosis, and brain tissue perfusion was acquired simultaneously to validate flow.Results:A total of 33 patients with symptomatic middle cerebral artery stenosis were included [mean age: 56 years; male: 63.6% ( n=21)]. The flow rates among patients with stenosis of <30%, 30%-49%, 50%-69% and ≥70% were (3.56±1.08), (2.96±0.94), (3.72±0.60) and (2.50±1.03) ml/s individually, demonstrating a decreased flow in subjects with severe (≥70%) stenosis ( F=4.34, P=0.008). Further analysis about forward flow and brain tissue perfusion showed that the significant negative correlation between absolute flow rate or relative flow rate and relative time to peak could only be established in subjects with poor collateral (collateral score: 0-2), with r=-0.76 and -0.61 individually, both P<0.05. Conclusion:4D flow MRI could be used as a quantitative flow assessment in subjects with intracranial artery stenosis, and its association with distal brain tissue perfusion depends on collateral status.

Background The safety of drinking water is closely related to people's health. In recent years, relevant studies have identified some health related problems with drinking water in Inner Mongolia Autonomous Region. The complex and diverse natural environment embraced by the vast jurisdiction of the region may lead to uneven drinking water quality across the region. Objective To evaluate eight chemicals including arsenic, cadmium, chromium (hexavalent), lead, mercury, fluoride, trichloromethane, and carbon tetrachloride in urban drinking water in Inner Mongolia Autonomous Region in 2021, and to provide reference for optimizing urban water supply system and ideas for further developing strategies to promote population health. Methods A total of 1228 monitoring sites were set up in urban areas of Inner Mongolia, and water samples were collected once in dry season (May) and once in wet season (August−September). Eight chemicals of interest in drinking water were detected according to the Standard examination methods for drinking water, and assessed for health risks using the health risk assessment model recommended by the United States Environmental Protection Agency (USEPA) and following the Technical guide for environmental health risk assessment of chemical exposure. Mann-Whitney U test was used to compare the concentrations of eight chemicals in urban drinking water by water seasons and water sample types. Results In 2021, a total of 2381 samples of urban drinking water were tested in the Inner Mongolia Autonomous Region, including 1195 samples in wet season and 1186 samples in dry season; 389 samples of finished water and 1992 samples of tap water. The positive rates of arsenic and fluoride were 26.25% and 96.77%, respectively. The positive rates of cadmium, chromium (hexavalent), lead, mercury, trichloromethane, and carbon tetrachloride were 6.22%, 16.63%, 6.09%, 16.67%, 18.98%, and 8.36%, respectively. The exceeding standard rate of fluoride was 4.87%. Trichloromethane and carbon tetrachloride were qualified in all samples. There were statistical differences in the concentrations of arsenic, cadmium, chromium (hexavalent), lead, and carbon tetrachloride in urban drinking water between water seasons (Z=−3.847, P<0.05; Z=2.464, P=0.014; Z=−3.129, P=0.002; Z=4.341, P<0.05; Z=4.342, P<0.05). Only fluoride concentration was found statistically different among different water sample types (Z=−2.287, P=0.022). The non-carcinogenic risks of ingestion and dermal exposure to each chemical in drinking water by water seasons and water sample types were all less than 1, but the P₉₅ total non-carcinogenic risks of oral exposure were greater than 1. The P₉₅ carcinogenic risks of oral exposure to some chemicals in drinking water by water seasons and water sample types were>10⁻⁴, which suggested carcinogenic risks, while the carcinogenic risks of dermal explore to chemicals were all less than 10⁻⁶. Conclusion In 2021, urban drinking water in Inner Mongolia Autonomous Region is generally safe, but arsenic, cadmium, chromium (hexavalent), lead, mercury, and fluoride still exceed the national limits, posing certain health risks.
