OBJECTIVE: To investigate the effects of aldosterone (Ald) on the proliferation and collagen synthesis of cardiac fibroblasts (CFs) in neonate rats and to research its mechanism. METHODS: The neonatal rat cardiac fibroblasts were induced by anchorage velocity-dependent separation method. SD rats were divided into control group, Ald (1.0?10-7 mol?L-1) group, Ald combined with spirolactone group and Ald combined with losartan group. After 24 h of exposure, CFs proliferation was measured by MTT assay and cell cycle distribution was determined with flow cytometer (FCM). Spectrophotography was used to detect the content of hydroxyproline and immunofluorescence staining method was applied to determine the protein expression of proliferation cell nuclear antigen (PCNA) and fibronectin (FN). RESULTS: As compared with control group, in Ald group the activity of CFs was increased as well as its percentage in S stage. The content of hydroxyproline and the protein expression of PCNA and FN were also increased while the percentage of CFs in G0/G1 stage was decreased (P0.05). CONCLUSION: Ald-stimulated CFs proliferation and collagen synthesis were mediated by activation of AT1 receptors and Ald receptor,and Ald receptor plays a major role. A corresponding increase in the protein expression of PCNA and FN in CFs may be related to the proliferation effect.

This study summarized the related clinical research literature of Chinese medicine sticking therapy for cancer pain from 2005 to 2015,and which is simple,convenient,effective,cheap and has a wide range of clinical applications in bone metastases cancer pain.Chinese medicine sticking theapy can be combined with a variety of clini-cal treatments to reduce toxic side effects,improve symptoms and the quality of life of patients,even though there are also shortcomings in treatment of bone metastases cancer pain and need new ideas of further research.

Objective To investigate the morbidity and cause of post-operative complications and quality of life for cervical carcinoma.Methods 100 patients were analysed retrospectively.The methods of operation included:class Ⅰ,20 cases;Class Ⅱ,20 cases;Class Ⅲ,20 cases;Class Ⅳ,40 cases.The quality of life in 68 patients with cervical cancer who received radiotherapy were evaluated.Results The common complications were in urinary system,including 26.0% of infection,25.0% urine retention and 3.0% fistula.And the other complications included 2.0% of incision infection,1.0% of lung infection,1.0% of pelvic infection and 1.0% of death related with operation.Multivariate analysis revealed that factors contributing to QOL were pain and depression before radiotherapy,nausea and vomiting during radiotherapy.Conclusions The some surgical modifying could decrease the morbidity of urinary infection and fistula.The quality of life in cervical carcinoma is affectd by multiple complex factors.

Similar to nitric oxide (NO) playing a key role in vascular regulating,carbon monoxide (CO) is another endogenous gaseous signal molecule after it.Under physiological condition,CO can relax vessels and inhibit the proliferation of vascular smooth muscle cells.CO may participate in the development of hypertension,atherosclerosis,pulmonary hypertension and vascular calcification under pathophysilogic condition.In this review,we summarized the production,metabolism and vascular regulation of endogenous CO under physiologic and pathophysiologic conditions.

Objective:To investigate the use of antibiotics in a hospital to improve the management and proper clinical utilization.Method:A total of 1268 patients discharged from the hospital in April 2007 were surveyed,and a statistical analysis was conducted.Result:The rate of antibiotics usage was 73.50%,and the rate of preventive usage was 52.47%, and the rate of combination usage was 46.14%.The antibiotics most widely used were cephalosporins,quinolones,nitroimidazoles and penicillins.Most antibiotics were used according to experience.And the cost of antibiotics was 22.68%in the total drug expenses of the hospital.New and expensive antibiotics were mainly the drugs in high expenditure.Conclusion:The problems are the higher rate of the application of antibiotics in the hospital,unclear indication for antibiotics usage to some doctors,substandard preventive usage in perioperative period,trend of using more expensive drugs and low rate of checking the pathogen.The results show that it is very important to strengthen the management of antibiotics usage in hospitals.

level and recommended nutrient intake)in China has been out-of-date.Therefore,it has became an urgent problem for Chinese Nutrition Society to re-evaluate the DRIs of vitamin D and make corresponding modifications.

Objective To explore the influencing factors of pharmacotherapy effect of ectopic pregnancy and nursing measures. Methods 569 patients with ectopic pregnancy using pharmacotherapy were retrospectively analyzed in our department. Results Among 569 patients,423 patients gained successful treatment,while 146 patients failed the treatment.Blood β-HCG level,diameter of ectopic mass showed by B ultrasound were influencing factors of pharmacotherapy effect.The higher β-HCG level,the longer diameter of ectopic mass showed by B ultrasound,the lower success rate of pharmacotherapy.The patients with β-HCG＜1000 mIu/ml,diameter of ectopic mass showed by B ultrasound less than 1 cm at admission acquired higher success rate of pharmacotherapy. Conclusions Patients with ectopic pregnancy who select conservative medication should be given pertinent psychological nursing,rigorous monitoring of disease condition and adverse reaction of drugs and timely and effective nursing measures,so that patients can get better nursing effect.

Today, the direction of litigation reformation is changing trial pattern to be trial-centered and making the trial substantialized. Under this background, the relevant provisions have been launched from the supreme people's court and other departments to make sure that the forensic expert will appear in court and accept cross-examination, and this phenomenon should be normalized and substantiated. In order to ensure the expert opinion can be fully and effectively cross-examined, the medico-legal expert should fulfill obligations, such as respect for the court, answer questions honestly and explain expert opinions. We find that some problems show up in this process: the rate of forensic expert appearing in court is low; the legal nature of expert opinion is not clear; the requirements are not clear;the conflict between forensic expert opinion and other forms of expert evidence, including auxiliary expert, is very clearly. Based on this situation, the author give some suggestions to the forensic expert: keep on learning to improve professional skill; improve the legal knowledge; pay attention to practice and strengthen the ability of expression.

METHODS:RP-HPLC was performed on the column of Venusil XBP-CN with mobile phase of acetonitrile-0.05 mol/L Sodium dihydrogen phosphate solution(pH value adjusted to 3.0 by phosphoric acid)(60∶40,V/V)at a flow rate of 1.0 ml/min, the detection wavelength was 230 nm,column temperature was 25 ℃,and volume injection was 20 μl. RESULTS:Levo-cetirizine hydrochloride chewable tablet showed good separation with related substances;the linear range of levo-cetirizine hydrochloride was 1.2-2.8 μg/ml(r=0.999 9);the quantification limit and detection limit was 1.4 ng/ml and 0.3 ng/ml,respectively;RSDs of preci-sion,stability and reproducibility tests were lower than 1%;recovery was 96.3%-105.0%(RSD=1.7%,n=9);the contents of re-lated substances were no more than 0.17%. CONCLUSIONS:The method is simple,sensitive,reproducible,accurate and reli-able,and can be used for the determination of related substances in Levo-cetirizine hydrochloride chewable tablet.
