Objective To evaluate the effect of sildenafil on the expression of tumor necrosis factor-alpha (TNF-α) in lung tissues of rats with pulmonary hypertension.Methods Twenty-four male Sprague-Dawley rats,aged 8 weeks,weighing 180-220 g,were randomly divided into 3 groups (n =8 each) using a random number table:control group (group C),pulmonary hypertension group (group PH),and sildenafil group (group S).Sildenafil 50 mg/kg was injected through a gastric tube into stomach once a day for 35 consecutive days starting from 1 day after lelf pneumonectomy in group S.Pulmonary hypertension was induced by left pneumonectomy and subcutaneous monocrotaline injected at 7 days after operation in PH and S groups.At 35 days after operation,mean pulmonary arterial pressure (mPAP),relative medial thickness of pulmonary artery (RMT),right ventricular systolic pressure (RVSP),and muscularization of small pulmonary arteries were measured in the lung.The ratio of the right ventricular weight to the sum of the weights of the left ventricle and septum (RV/(LV + S)) was calculated.The expression of TNF-α mRNA and protein was determined using RT-PCR and Western blot analysis,respectively.Results Compared with group C,mPAP,RVSP,muscularization of small pulmonary arteries,RMT and RV/(LV + S) ratio were significantly increased,and the expression of TNF-α mRNA and protein was upregulated in group PH,and RVSP,muscularization of small pulmonary arteries and RV/(LV + S) ratio were increased in group S.Compared with group PH,mPAP,RVSP,muscularization of small pulmonary arteries,RMT and RV/(LV + S) ratio were significantly decreased,and the expression of TNF-α mRNA and protein was downregulated in group S.Conclusion Sildenafil can down-regulate the expression of TNF-α in lung tissues of rats with pulmonary hypertension,inhibit reconstruction of pulmonary artery,and decrease the pulmonary arterial pressure.

Objective To explore the clinical characteristics and influencing factors of primary nephrotic syndrome (PNS) combined with hypercoagulability in children. Methods The clinical data of 57 children with primary PNS were analyzed retrospectively. The clinical features and treatment were compared among high coagulation state group, non high coagulation state group and control group (20 children). At the same time, the differences between the simple nephrotic syndrome group (SNS) and nephritic syndrome group (NNS) in hypercoagulable state were analyzed. In addition, the correlation analysis was performed. Results Among 57 patients, there were 50 patients in high coagulation state group and 7 in non high coagulation state group. There was no significant difference in gender, age and clinical manifestations between two groups (P>0.05). The platelet (PLT) count, platelet aggregation (PCT), albumin (Alb), fibrinogen (Fib), D-dimer (D2) were significantly higher than those in the control group, and there were statistically significant differences (P all<0.01). There were significant differences in the levels of PLT, Fib, D2 and complement C4 between hypercoagulable state group and non hypercoagulable state group (P all<0.05). There were significant differences in HCT, TC, LDL, PT and complement C3 levels between SNS group (n = 32) and NNS group (n =18) in 50 patients with high coagulation state (P<0.05). There was positive correlation between HCT and complement C3 (r=0.30, P<0.05), while there was no correlation between PLT and other indices (P>0.05). All of the 57 patients were improved and has no thrombosis after the treatment. Conclusion Children with primary PNS were usually associated with different degrees of hypercoagulable state, and PLT, Fib, D2 could be used as reference indices for the severity of hypercoagulable state, and the activation of complement system might be related to the occurrence and development of hypercoagulable state.

To explore the relationship and possible mechanism of reproductive function of bisphenol A (BPA) with polycystic ovary syndrome (PCOS).Serum specimens were collected from 43 PCOS patients and 37 healthy women.And the level of BPA was detected by enzyme-linked immunosorbent assay (ELISA).The serum level of BPA in PCOS were significantly higher than that in the control group.And the inter-group difference was significant (P ＜ 0.05).The patient level of BPA was positively related with obesity and basic luteinizing hormone (LH) (P ＜ 0.05).In the PCOS group,no significant correlation existed between hyperandrogenemia and non-hyperandrogenemia (P ＞ 0.05).Although no difference existed between insulin and non-insulin resistance,the level of BPA in insulin resistance group was lower than in non-insulin resistance group.A higher level of BPA may be associated with obesity and basic LH in PCOS.

Objective The homological analysis of a foodborne disease outbreak event that occurred on July 15, 2022, in Sanya was carried out to provide scientific basis for clinical treatment, incident tracing and prevention and control, and to explore the feasibility of pulsed field gel electrophoresis (PFGE) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) in the homology analysis of Salmonella bacteria. Methods The traceability analysis of food poisoning incidents was accurately analyzed through the combination of traditional bacterial detection methods, PFGE, MALDI-TOF MS and the clinical symptom, epidemiological characteristics. Results In this outbreak, 14 cases of poisoning symptoms such as fever, nausea, and vomiting appeared, all of which had a history of dining in the same restaurant, with similar onset and clinical manifestations. Among them, one was the chef who made the fried rice in the restaurant. The pathogen culture and identification showed that it was caused by Salmonella typhimurium and Salmonella choleraesuis. Among the 14 cases of patients, 5 cases of Salmonella choleraesuis, 3 cases of Salmonella typhimurium, with the positive rate of 57.14% (8/14). One case of environment and two cases of food were detected. The result of PFGE showed nine PFGE types, 95.00% homology for 7 strains, and 94.00% homology for 4 strains. Conclusions The food poisoning was caused by eating egg fried rice containing Salmonella choleraesuis and pork intestine containing Salmonella typhimurium. In the future, , it is necessary to strengthen the risk monitoring of food contamination and harmful factors, to ensure food safety from the source of food supply, and to prevent the occurrence of foodborne infection events. At the same time, it is also crucial to standardize the health check of related personnel, and to conduct multi-channel education on the harm and prevention of foodborne diseases.

The enhanced recovery after surgery (ERAS) protocol is an evidence-based perioperative care pathway, which is to reduce the perioperative stress and metabolic variation, with the ultimate goal of improving patient recovery and outcomes. This article reviews some hot issues in the clinical practice of ERAS in China. Currently, the concept and pathways of ERAS are very consistent with China's medical reform, and the basic principle of "safety first, efficiency second" should be adhered to. In specific clinical practice, multidisciplinary cooperation, the improvement of surgical quality and the implementation of prehabilitation pathway should be advocated. In addition, the ERAS approaches should be implemented individually to avoid mechanical understanding and dogmatic implementation. The implementation of ERAS and its clinical outcome should be audited to accumulate experience, and a feedback mechanism should be established to improve the outcome continuously. In clinical practice, "fast recovery" should not be the sole purpose. For patients, the decrease in the risk of readmission rate is more important as compared to discharge rate. Additionally, the disparities between the development of ERAS clinical research in China and that in the world are also analyzed in this review. A national ERAS database should be established on the basic platform of academic groups to ensure the development of high-quality clinical research in China.

INTRODUCTIONThe level of participation is an important factor influencing rehabilitation outcome. However, few studies have evaluated rehabilitation participation and its clinical predictors in patients with stroke. This study aimed to establish the level of participation in patients with stroke undergoing inpatient rehabilitation, and define the clinical predictors for participation.

METHODSThis was a prospective observational study of first-time patients with stroke admitted to a rehabilitation centre over a 12-month period. The primary outcome measure was the level of rehabilitation participation as measured on the Pittsburgh Rehabilitation Participation Scale (PRPS). PRPS measurements were made one week after admission and one week before planned discharge from inpatient rehabilitation. Other outcome measures evaluated were the National Institute of Health Stroke Scale, Functional Independence Measure (FIM), Elderly Cognitive Assessment Questionnaire (ECAQ), Centre for Epidemiologic Studies-Depression Scale, Fatigue Severity Scale (FSS), Lubben Social Network Scale-Revised, and Multidimensional Health Questionnaire.

RESULTSA total of 122 patients with stroke were studied. The mean PRPS score on admission was relatively high at 4.30 ± 0.90, and this improved to 4.65 ± 0.79 before planned discharge (p < 0.001). On multivariate analysis, the mean PRPS score on admission was predicted by FIM, EACQ and FSS scores on admission, but not by variables such as age, gender, depression, social support, or health attitudes and beliefs.

CONCLUSIONPatients with lower levels of participation were more likely to be functionally dependent, cognitively impaired and have more fatigue. We suggest that in addition to cognition, fatigue should be routinely screened in patients with stroke undergoing rehabilitation.

OBJECTIVETo study in vitro anti-tumor activity of phaseoloideside E (PE) with human hepatoma HepG2 cells as the objective.

METHODMTT assay was adopted to detect the cytotoxic effect of PE of different concentrations on HepG2 cells after being processed for 48 h. Changes in morphology of PE-processed cells were observed under an optical microscope and fluorescence microscope. DNA agrose gel electrophoresis was used to detect the DNA ladder, an important characteristic of cell apoptosis. The expression levels of Bax and Bcl-2 were determined by western blot assay.

RESULTPE dramatically repressed the viability of HepG2 cells. Typical morphological changes of apoptosis had been detected by both direct microscopic observation and Hoechst 33,258 staining. Typical DNA Ladder was also observed by agarose gel electrophoresis in the administration group, but it did not exist in the control group. Western blot showed that the expression of Bax was up-regulated and Bcl-2 was down-regulated.

CONCLUSIONAbove data demonstrates that PE can induce apoptosis in human hepatoma HepG2 cells, and indicate that PE-induced expression level changes of Bax and Bcl2 may be related to the apoptosis-induction effect.
