To evaluate the protective effect of anti-digoxin antiserum on hypoxic injury myocardium and its mechanism.Methods It was observed that different concentration anti-digoxin antiserum effect on endogenous digitalis-like factor and cell membrane ATPase activity in hypoxic myocardium model.Results The level of endogenous digitalis-like factor was remarkably higher,cell membrane ATPase activity were remarkably lower in hypoxic group than those of normal group;anti-digoxin antiserum can resume membrane ATPase activity.Conclusion Rise of endogenous digitalis-like factor was basic of molecular biology of myocardial damage during myocardial hypoxia.Anti-digoxin antiserum has lightened myocardial injury and has protective effect on hypoxic myocardium by against effect of endogenous digitalis-like factor.

AIM: To evaluate the antagonistic effect of anti - digoxin antiserum on hypoxic myocardium and its mechanism. METHODS: It was observed that different concentration of anti-digoxin antiserum effect on endoxin and cell membrane ATPase activity in hypoxic myocardium model. RESULTS: The endoxin level was much higher, cell membrane ATPase activity was much lower in hypoxic myocedium than those of noed; anti-digoxin antiserum can resume membrane ATPase activity. CONCLUSION: Rise of endoxin was basic in molecular biology of myocar- dial damage during myocardial hypoxia. Anti - digoxin antiserum decreased myocardial damge and has protective ef- fect on hypoxic myocardium by antagonistic effeCt of endoxin.

Objective:To analyze the medication of one patient with ulcerative colitis to provide pharmaceutical care and support for rational drug use in patients with ulcerative colitis.

Results:The compliance, therapeutic effect and medication safety of the patient were all im-proved by giving clinical drug rationalization suggestions and targeted medication monitoring and education, which fully embodied the necessity of work of clinical pharmacists in the medication of patients. Conclusion:Through case analysis, clinical thinking of clinical pharmacists can be developed to promote rational drug use, avoid adverse drug reactions and achieve optimal effect of drug treatment.

AIM: To investigate the effect of low concentration desflurane on hemodynamics and fibrinolysis in patients during general anesthesia. METHODS: Twenty eight ASA grade Ⅰ-Ⅱ patients during general anesthesia, scheduled for elective chest surgery, were studied, and hemodynamics and fibrinolysis were observed after inhalation of desflurane at 0.5 and 1.0 MAC , respectively. RESULTS: Compared with those before anesthesia, SBP, DBP, and MAP remarkably decreased and HR significantly increased at intubation. However, the changes were more remarkable than those of before anesthesia when inhalation of desflurane at 0.5 and 1.0 MAC ; blood pressure did not further decreased; and HR did not increased in comparison with intubation. The level of plasma tissue plasminogen activator (t PA) remarkably increased and the level of plasma plasminogen activitor inhibitor (PAI) significantly decreased when inhalation of desflurane. The level of plasma t PA further increased and the level of plasma PAI further decreased as inhalation of increased desflurane concentration. CONCLUSION: There are some effects of low concentration desflurane on hemodynamics and fibrinolysis in patients with chest surgery during general anesthesia.

Objective To study the absorption features of isoimperatorin in intestine of rat.Methods Establish a single-pass intestinal perfusion model of rat,take phenolsulfonphthalein as a marker for the detection of isoimperatorin concentration from crude extracts of notopterygium,and observe the absorption features of isoimperatorin and its reference substance in intestine of rat.Results The content of isoimperatorin in crude extracts was (0.43±0.02)% (n=5).The absorption parameters of duodenum,jejunum,ileum,colon were (5.28±0.82),(4.47±0.56),(4.17±0.94),(4.32±0.68)×10-5 cm·s-1,respectively.There were no significant differences among them (P>0.05).Compared with the reference substance of isoimperatorin,crude extracts showed better absorption features.Conclusion Isoimperatorin from crude extracts have better characteristics of absorption.This study can provide theoretical basis for design of notopterygium oral formulation.

Objective To evaluate the plasma D-dimer level in the patients of type 2 diabetes mellitus with hypertension and investigate their correlation.Methods Eighty-five subjects were divided into three groups according to clinical manifestation:control group:20 subjects ; type 2 diabetes mellitus group:21 subjects; type 2 diabetes mellitus combined with hypertension group:44 subjects.The level of plasma D-dimer was measured and the difference was compared between groups.The results were showed as mean ± sd,and the difference was compared using ANOVA Test ( SPSS13.0).Results The plasma D-dimer concentrations in normal control group was ( 102.15 ± 32.48 ) μg/L,in single type 2 diabetes mellitus was ( 148.62 ± 80.99 ) μg/L,while plasma concentrations in type 2 diabetes mellitus combined with hypertension was ( 206.28 ± 92.99 ) μg/L.plasma D-dimer concentration was higher in single type 2 diabetes mellitus than that in normal control cases( P ＜0.05) ;And plasma D-dimer concentration was also found increased in type 2 diabetes mellitus combined with hypertension when compared with control group (P ＜ 0.01 ) ;And there was also significant difference on plasma D-dimer concentration between single type 2 diabetes mellitus and type 2 diabetes mellitus combined with hypertension cases ( P ＜ 0.05 ).Conclusion The plasma levels of D-dimer was increased obviously in single type 2 diabetes mellitus and type 2 diabetes mellitus combined with hypertension,it may be related to the imbalance of coagulation and fibrinolytic system.Monitoring of plasma D-dimer concentration in type 2 diabetes and patients with hypertension may have important clinical implications for the prevention of thrombotic diseases.

By convenience sampling method, A survey was conducted on perimenopausal women in the communities around Chongqing Health Center for Women and Children from July to August 2019. Project analysis, exploratory factor analysis, confirmatory factor analysis, Pearson correlation analysis and reliability test were used to evaluate the questionnaire.Results:Two rounds of questionnaires were distributed in this study. In the first round, 260 questionnaires were distributed, 249 valid questionnaires were recovered, and the effective recovery rate was 95.8% (249/260). In the second round, 249 questionnaires were distributed, and the effective recovery rate was 96.4% (240/249).

Acute respiratory distress syndrome (ARDS) refers to acute diffuse lung injury caused by a variety of intrapulmonary and/or extrapulmonary factors such as infection and trauma. Uncontrolled inflammatory response is the main pathological feature. Different functional states of alveolar macrophages have different effects on inflammatory response. Transcription activating factor 3 (ATF3) is a fast response gene in the early stage of stress. In recent years, it has been found that ATF3 plays an important role in regulating the inflammatory response of ARDS by regulating the function of macrophages. This paper reviews the regulatory effects of ATF3 on alveolar macrophage polarization, autophagy and endoplasmic reticulum stress and its effects on the inflammatory process of ARDS, aiming to provide a new research direction for the prevention and treatment of ARDS.

High mobility group protein B1 (HMGB1), a highly conversed non-histone nucleoproteins with strong pro-inflammatory property, is one of the inflammatory mediator of the acute respiratory distress syndrome (ARDS). Numerous studies have confirmed that HMGB1 regulates ARDS by binding to receptor for advanced glycation end product (RAGE), Toll-like receptor (TLR) and etc. And it can significantly increase the mortality of ARDS. But the mechanism of HMGB1 release is still unclear. This study focuses on the HMGB1 release progress, which connected with Janus kinases/signal transducer and activator of transcription (JAK/STAT), nuclear factor-κB (NF-κB), Notch, inflammasome, tumor necrosis factor (TNF), mitogen-activated protein kinase (MAPK), reactive oxygen species (ROS), peroxisome proliferator-activated receptor (PPAR) and other signaling or dependent pathways in ARDS.
