ABSTRACT
AIM:To observe the expression of hypoxia-inducible factor-1α (HIF-1α) , vascular endothelial growth factor A (VEGFA) and vascular endothelial cadherin (VE-cadherin) in cultured rat renal glomerular endothelial cells (rRGECs) exposed to glucose at different concentrations in vitro, and to verify the hypothesis that salidroside attenuates high glucose (HG) -induced injury of rRGECs by boosting HIF-1αlevel.METHODS:rRGECs were divided into 4group:normal glucose (NG) group, HG groups, hypertonic group and salidroside+HG group.The viability of rRGECs was measured by MTT assay.The mRNA expression of VEGFA, VE-cadherin and HIF-1αwas detected by RT-qPCR.The protein expression of HIF-1αwas determined by Western blot.RESULTS:Compared with NG group, the mRNA and protein expression of HIF-1αwas increased when the rRGECs were treated with glucose at concentration of 20 mmol/L for 24h (P<0.01).Compared with NG group, the mRNA expression of HIF-1αwas decreased in HG groups for 120 h (P<0.05).Compared with NG group, the mRNA expression of VE-cadherin was significantly down-regulated in HG groups for24 h or 120 h (P<0.05).Compared with NG group, the mRNA expression of VEGFA was increased in HG groups at 24h (P<0.05) , while the mRNA expression of VEGFA was decreased at 120 h (P<0.05).Compared with NG group, no statistical difference in the mRNA expression levels of HIF-1α, VE-cadherin and VEGFA in DM group was observed.Compared with HG group, salidroside promoted the viability of rRGECs (P<0.01) , and up-regulated the mRNA expression of HIF-1αand VE-cadherin, and the protein expression of HIF-1α (P<0.05).CONCLUSION:High glucose regulates HIF-1αexpression in rRGECs in connection with cell viability, the concentration of glucose, the culture time and HIF/VEGF signaling.Salidroside promotes rRGEC growth against high glucose-induced cell apoptosis via up-regulating the expression of HIF-1α.
ABSTRACT
OBJECTIVE:To explore the clinical efficacy and safety of oxymatrine membrane,rhEGF gel respectively com-bined with Yunnan baiyao for postoperative cervical wound after LEEP. METHODS:300 patients with cervical intraepithelial neo-plasia(CIN)Ⅱ and Ⅲ were divided into group A,B,C(100 cases in each group)based on CIN grading and stratification and random sampling in each stratification. After conventional LEEP,patients in group A were cleaned the wound by 0.9% Sodium chloride injection,spraying Yunnan baiyao powder,once only after surgery;patients in group B were additionally given recombi-nant human epidermal growth factor (rhEGF) on the basis of group A,once every week after surgery,for 3 weeks;patients in group C were additionally given oxymatrine membrane on the basis of group A,1 tablet every evening after surgery,for 2 weeks. Postoperative bleeding,bleeding duration,rebleeding and duration after postoperative bleeding stopped,postoperative drainage du-ration,the incidence of adverse reactions in 3 groups were observed. RESULTS:The patients of postoperative bleeding,bleeding time ≥7 d and rebleeding after stopping bleeding in group B were significantly lower than group A;the incidence of bleeding time ≥7 d in group C was significantly lower than group A,the proporition of postoperative drainage duration for less than 7 d was significantly higher than group A,for 8-13 d was significantly less than group A;early wound healing rate in group B and group C were significantly better than group A,with statistical significances (P0.05),and there were no obvious adverse reactions in 3 groups. CONCLU-SIONS:Oxymatrine membrane and rhEGF gel respectively combined with Yunnan baiyao have better healing than Yunnan baiyao alone,do not increase the incidence of adverse reactions,while there is no significant difference in oxymatrine membrane and rhEGF gel.
ABSTRACT
Objective To probe into the perioperative nursing method during osterior fusion and fmation for idiopathic scoliosis. Methods The study involved 31 patients with idiopathic scoliosis treated with posterior correction nails and selective spinal fusion with hook-rod system fixation.The severe patients were treated with extensive posterior release or anterior correction and fusion posterior to release.Before the operation,the patients were administrated with mental nursing,lung function exercise,self-elongation exercise,wake-up pilot training,self-image appraisement and bed and life skills exercise.After the operation,an observation was done on the change of nervous system,propor turning the body over best clinostatism,drainage tube care,respiratory passage care,functional exercise instruction and discharge instruction. Results The operation was accomplished successfully in all the patients,which showed that the body height was increased 2-15 cm.There found no complications including loosening or breakage of the nails or sticks,nervous system injury,incisional wound infection or press~e sore. Conclusion Preoperative sufficient preparation and fine postoperative nursing are important guarantee to successful operation and fast rehabilitation.
ABSTRACT
Objective To understand the changing trends of non-communicable diseases (NCDs) in Xinjiang Production and Construction Corps from 1998 to 2008.Methods A stratified-cluster random sampling based cross-sectional NCDs survey was carried out in 2008,and using the data of NCDs from the health service surveys in 1998 and 2004,in Xinjiang Production and Construction Corps.The prevalence rate of NCDs was standardization according to age proportion of the population being surveyed in 1998.Results In 1998,2004 and 2008,the prevalence rates of NCDs in Xinjiang Production and Construction Corps were 17.26%,25.61%,24.85% while the Standardized rates of NCDs were 17.26%,23.54% and 20.49% respectively.The prevalence rates of NCDs were statistically significant different in 35-,45-,55- and over 65 age groups in 1998,2004 and 2008 which showed an consecutive upward trend.The prevalence rates of hypertension,diabetes,cerebrovascular disease,coronary heart disease and chronic obstructive pulmonary disease increased significantly from 1998 to 2008.The prevalence rate of hypertensive disease among 25- age group,diabetes among 35- age group,cerebrovascular disease and coronary heart disease among 45- age groups showed an increasing trend.Conclusion Cardiovascular and cerebrovaseular diseases,together with diabetes were the fastest increasing ones over the past 10 years and becoming the major diseases,making the Xinjiang Production and Construction Corps an aging population.NCDs should be prioritized in the health development plan.Targeted health education should be carried out in the whole population,together with other interventions as well as management programs on chronic diseases to reduce the prevalence of NCDs.

ABSTRACT
OBJECTIVE: To provide reference for the improvement of management quality of high-alert medications in ward area. METHODS: Risk management was used to estimate risk factor of commonly used high-alert medications in ward area. Then the homologous management measures were formulated based on potential risk. RESULTS: With enforcement of risk management, risk awareness of relevant responsible person was strengthened. They knew more knowledge about high-alert medications and its rate increased from 60% to 96%. The phenomena such as nonstandard storage and placement of drugs, unclear identification had never happened again. CONCLUSION: The application of risk management in high-alert medications contributes to improve anti-distress awareness of relevant responsible person, guarantee safety of drug use and enhance the quality of care.
