ABSTRACT
OBJECTIVE: To analyze the role and significance of promoting the construction of health enterprises in the prevention and control of coronavirus disease(COVID-19) pandemic. METHODS: The corresponding clauses in the Guidelines for Prevention and Control Measures for Restoration of Work and Production in Enterprises and Public Institutions(hereinafter referred to as the Guidelines) in the Code for Construction of Health Enterprises(Trial)(hereinafter referred to as the Code) were analyzed by analogy method. A convenient sampling method was used to select 78 health enterprises, and the questionnaire survey was used to investigate the one-time approval rate for restoration of work and production. The random sampling method was adopted to select 5 health enterprises for field inspection and qualitative interview, so as to understand the restoration of work and production and pandemic prevention and control in these health enterprises. RESULTS: The 16 clauses in the Guidelines were involved in the Code to some extent. Among them, 2 clauses in the Code were generally applicable to the 16 clauses in the Guidelines, accounting for 100.0%(16/16). There were 3 and 4 clauses in the Code that were applicable to the provisions of the Guidelines, accounting for 62.5%(10/16) and 12.5%(2/16) respectively. All the 78 health enterprises in Jiangsu Province were immediately approved for their application for resuming work and production. The results of in-depth interviews showed that the adoption of the construction framework and concept of health enterprises by relevant enterprises was beneficial for the prevention and control of COVID-19 pandemic. CONCLUSION: The concept and framework of construction of health enterprises are helpful for enterprises to carry out prevention and control work during COVID-19 pandemic, and comprehensively promote the construction of healthy China.
ABSTRACT
This paper rounded up the resources and advantages leveraged by the hospital′s burn and plastic surgery department as a national key discipline. The department practiced medical services for chronic wounds in the regional hierarchical medical system for chronic wounds to promote the development medical alliances. IT development of the hierarchical medical network has achieved disease information sharing, namely centralized patients screening, patients referral confirmation, mutual recognition of test results, online consultation and treatment follow-up. Other achievements include standardization of medical criteria for chronic wounds by means of effective integration of resources imbalance within the network and improvement of internal medical regulations; elevation of primary level innovation capacity and services by means of high-caliber specialists working at primary institutions and mutual exchanges in between; effective medical cost control via guarantee system building, thus enhancing the public benefit nature of public hospitals. The paper also probed into problems and solutions expected in the way of promoting the chronic wound hierarchical medical system.
ABSTRACT
OBJECTIVE:To observe the effects of bisoprolol combined with conventional triple therapy on the efficacy and re-lated indexes of patients with rheumatic heart valvular disease (RVD) combined chronic heart failure. METHODS:110 patients with RVD combined with chronic heart failure were randomly divided into observation group(55 cases)and control group(55 cas-es). All patients were treated with oxygen inhalation,anti-infection,correcting electrolyte imbalance,controlling arrhythmia,and giving digitalis drugs and diuretic drugs(it can be disabled after edema symptom being controlled);based on it,control group was given Enalapril tablet with initial dose of 2.5 mg,once to twice a day,then adjusted to 10-20 mg after 1 week,twice a day+20 mg Spironolactone tablet,once a day+10 mg Propranolol tablet,once a day. Observation group was additionally given Bisoprolol fuma-rate tablet initial dose of 1.25 mg,once a day,and then increased to 10 mg based on condition improved and tolerability after a meal,once a day. They were treated for 12 weeks. Clinical efficacy,and LVEF,LVEDD,LVESD,SBP,DBP,HR before and af-ter treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant (P0.05). After treatment,LVEF in 2 groups were significantly higher than before,and observation group was higher than control group,LVEDD,LVESD,SBP, DBP and HR were significantly lower than before,and observation group was lower than control group,the differences were statis-tically significant(P0.05). CONCLU-SIONS:Based on conventional treatment,bisoprolol combined with conventional triple therapy shows good efficacy in the treat-ment of RVD combined chronic heart failure,it can improve cardiac function,with good safety.
ABSTRACT
BACKGROUND: Hundreds of mouse embryonic stem cell lines are established presently. Most of these cell lines are collected from 129, C57BL/6J and BALB/C mice. Success rate of creating embryonic stem cell lines with Kunming mice is very low. OBJECTIVE: To explore the method of isolation and culture of murine embryonic stem cells of kunming species to increase the efficiency of establishment of embryonic stem cell lines from Kunming species mouse. DESIGN, TIME AND SETTING: The cell experiment was performed at the Chongqing Key Laboratory of Neurology from April 2006 to June 2007. MATERIALS: Blastocysts of 3.5 days and 4 days from Kunming species mouse were collected. METHODS: The blastocysts of 3.5 days and 4 days from Kunming species mouse were cultured on the fibroblast cell feeder layers for 4-5 days, and the cells from inner cell mass were isolated and subsequently cultured in vitro in 2.5 g/L trypase-0.4 g/L ethylenediamine tetraacetic acid (EDTA) and 1 g/L trypase-0.2 g/L EDTA at room temperature for 2-4 minutes. Embryonic stem cell colony was mechanically straggled. MAIN OUTCOME MEASURES: Colony growth was observed and determined by alkaline phosphatase staining, OCT-4 staining and karyotype analysis. RESULTS: Adherence rate, inner cell mass frequency and cloning efficiency of 4 day post coitum (dpc) embryo were higher than those of 3.5 dpc embryo (P
ABSTRACT
Objective To explore the effect of embryonic stem cells(ESCs) differentiating into cardiomyocytes(CM) by cardiomyocytes.Methods The blastocytes of 3.5 d from Kunming mouse,cultured on mouse embryonic fibroblaste cell feeder layers for 4～5 d,the mouse ESCs were isolated and subsequently cultured.Day 2～3 embryoid bodies(EBs) were derived from ESCs of passage 3 to 5 and then incubated with neonatal cardiomyocyte(CM) to induce into cardiomyocytes and the expression of cardiac specific cardiac troponin-T(TnT) and ?-actin were detected by immunofluoresence.Results The rhythmic beating embryoid bodies were observed on day 3 and reached 93% of rhythmic beating embryoid bodies on 12 day in group 2.All the beating cardiomyocytes derived from ESCs expressed cardiac-specific proteins for TnT and ?-actin,and the group induced by direct cell contact acquired the highest differentiating ratio as 56.5%,and was the highest differentiating ratio compared with other groups(P
