OBJECTIVE:To investigate effect of valsanan on heart function in patients with chronic heart failure(CHF).METHODS:A total of 113 CHF patients were assigned into 2 groups.Both group received routine therapy and observation group were additionally treated with valsanan.Clinical efficacies of 2 groups before and after treatment were observed in terms of cardiac function classification,LVIDD,SV,CO,LVEF and 6 min walking test.RESULTS:In observation group,the incidence of improvement of the cardiac function was higher than in control group(P

Object To investigate the pathological changes,physiological condition,neurobehavior and motor development of the 3-day-old rats with ischemic brain injury.Methods Ninety six 3-day-old male Sprague-Dawley rats were randomly assigned to experimental and control groups.Occlusion of both carotid arteries was performed in the experimental group,while the rats in the control group only received skin incisions without carotid ligation.Physical examinations and neurobehavioral development of the rats were recorded daily from the first day after operation until 3 weeks after birth,including weight,eye opening, incisor eruption,ear unfolding,righting reflex,negative geotaxis,limb placing and grasping reflex. Specimens of the brain tissue were obtained in 24 hours after operation and 3 weeks after birth for the hematoxylin-eosin staining and immunohistochemistry staining to investigate the pathological changes.All the reaults were compared between the 2 groups.Results Compared with the control group,rats in the experimental group were found growth retardation,suppression of primitive reflexes and impaired motor abilities (P < 0.05 ).The brain tissue obtained from the rats after operation showed white matter rarefaction,liquefaction and microglia hyperplasia with Hematoxylin-eosin staining and myelin formation disorder with immunohistochemistry staining.Conclusions Ischemic brain injury of the 3-day-old rats could result the mental retardation,neurobehavioral and motor development disorder because of the white matter injury.

Objective To investigate the effect of elemene on leptin, AFP and liver function of patients with advanced liver cancer.Methods 73 cases with advanced liver cancer of our hospital were selected and according to the random number table method were randomly assigned for two groups:control group (37 cases) were given routine clinical therapy;experimental group (36 cases) were treated on the basis of the control group with elemene injection.leptin, AFP ,CRP and liver function were compared after the treatment.ResuIts Compared with control group post-treatment, the leptin level in the experimental group was higher, CRP was lower(P<0.05); the serum level of AFP, CEA and CA199 were lower (P<0.05), the ALT, TBIL, AST, PT were lower ( P<0.05 ) , and the total effective rate was significantly higher ( P<0.05 ) .ConcIusion Elemene injection can improve liver function, elevate serum leptin level, reduce the levels of CRP, tumor marker levels and improve the quality of life .

OBJECTIVE:To probe into the status quo and requirements of drug utilization in Haiqin Sanatorium Area of Nanjing Military Region Hangzhou Sanatorium.METHODS:The drug utilization in 710 convalescents in Sanatorium Area from May 2007 to April 2008 was analyzed statistically.RESULTS:A total of 10 categories of drugs were used in the 710 convalescents,chiefly including anti-cold drugs,antihypertensive drugs,drugs for external use,antimicrobial agents,ophthalmic drugs,otorhinolaryngological drugs,vitamins and gastrointestinal drugs.The rate of drug use conforming diagnosis was 87.32%.Oral administration occupied 71.13%.CONCLUSION:The drug utilization in convalescents in Haiqin Sanatorium Area is basically rational.However,there are also some unreasonable points in the drug utilization which remain to be tackled further.

Objective To evaluate the clinical values of human papilloma virus(HPV)testing in screening for women of early cervical cancer lesion.Methods 282 cases of cervical screening of patients had received cervical exfoliated cells collection,at the same time for a liquid thin-layer cytology test(TCT)and HPV genotyping detection.Abnormal results received histologic examina-tion,the results regarded as the diagnostic gold standard by pathological examination.Results In HPV DNA positive group(126 cases),by liquid based cytology,NILM,ASCUS,LSIL,HSIL and SCC were found in 53,22,32,18,1 cases,respectively.His-topathologic examination positive rate was 42.86%.In HPV DNA negative group(156 cases),there were 133 cases with NILM,16 cases with ASCUS,and 7 cases with LSIL.Histopathologic examination positive rate was 11.54%.Two groups of patients with pathologic positive rate compared,the difference was statistically significant(P <0.01 ).High risk type HPV detection rate in-creased with the increased degree of cervical lesions.Conclusion Women of early cervical cancer and precancerous lesions in the screening line HPV detection has important significance.

Objective To explore the effect of dexmedetomidine preconditioning on antioxidant ability in Rats Brain with focal cerebral ischemia/reperfusion.Methods Forty-two healthy male SD rats,weighted 250-280 g,were randomly divided into three groups (n = 14):sham-operation group (group Sham):in which carotid artery was exposed but MCAO was not performed;ischemia/reper-fusion group(group IR):NS were injected intraperitoneally at 30 minutes before the MCAO;dexme-detomidine group (group Dex):dexmedetomidine 100 μg/kg were injected intraperitioneally injected at 30 minutes before the MCAO.Focal cerebral ischemia-reperfusion (IR)model in rats was made by transient occlusion of the middle cerebral artery occlusion (MCAO)using a nylon thread with rounded tip inserted into internal carotid artery and advanced cranially until resistance was met.MCAO was maintained for 2 hours followed by 24 hours reperfusion.Neurologic deficit scores(NDS),the infarc-tion volume as well as the activities of endogenous antioxidants (such as superoxide dismutase(SOD), glutathione peroxidase(GSH-PX),glutathione reductase (GR),catalase (CAT))in ischemic brain were evaluated 24 h after reperfusion.Results Compared to group Sham,the neurologic deficit scores and the infarction volume in group Dex and IR were significantly higher,but the concentration of SOD,GSH-PX,GR,CAT were significantly lower(P <0.05).Compared to group IR,however,the neurologic deficit scores and the infarction volume in group Dex were significantly lower,but the concentra-tion of SOD,GSH-PX,GR,CAT were significantly higher (P <0.05).Conclusion Dexmedetomidine can protect the brain from focal cerebral ischemia-reperfusion injury,and its mechanism maybe relate to preserving the activities of endogenous antioxidants.

Autophagy can be activated after cerebral ischemia and involved in the occurrence and development of ischemic brain injury. Therefore, the study of autophagy related signal transduction pathways may provide a new therapeutic target for ischemic brain injury. This article reviews the signal transduction pathways of autophagy after cerebral ischemia.

Establishing harmonious physician-patient relationship is importamt to set up the harmonious society.Some hospitals try in recent years a line the single disease grows the price control charges,which suggest its importamt role in seting up harmonious physician-patient relationship,and greatly attract public's concern as the new measure in this aspect.

OBJECTIVE: To establish the HPLC method for the determination of chloramphenicol and dapsone in compound chloramphenicol cream. METHODS: The analytical column was Hypersil ODS and the mobile phase consisted of 0.1%sodium heptanesulfonate solution (a mixture of 0.1% sodium heptanesulfonate 500 mL and dimethylformamide 5 mL plus acetic acid glacial 0.5 mL)-acetonitrile (75∶25) at a flow rate of 1.0 mL?min-1. The detection wavelength was 272 nm and the sample size was 20 ?L. RESULTS: The linear ranges of chloramphenicol and dapsone were 25.59～153.54 ?g?mL-1 (r=0.999 9) and 12.57～75.42 ?g?mL-1 (r=0.999 9), respectively. The average recovery rates were 100.62% (RSD=0.92%) and 100.93% (RSD=1.22%), respectively. CONCLUSION: The method is simple and accurate and can be used for the quality control of compound chloramphenicol cream.

It is the traditional virtue of Chinese to be honest, and honest-trust is the foundation of the development of market economy. The phenomenon of honest-trust lacking in the field of medical care is a comprehensive result for many factors. It's a new subject to advocate sincere service and spread honest-trust culture for the construction of medical ethics. Therefore, we should put emphasis on the medical ethics education, strengthen the consciousness of sincere service, perfect the criteria of medical ethics, and set up the credit system of medical organization and medical staff.
