Objective To investigate the relationship between the insertion/deletion(I/D) polymorphism of the angiotensin convcer-(ting) enzyme(ACE) gene and congenital heart disease(CHD) and to quest the predisposing gene of congenital heart disease by analyzing the polymorphism of the ACE gene in patients with CHD.Methods Sixty-eight patients with CHD were served as observing group,sixty-four patients without CHD as control group.We drew DNA of leukocyte from blood by the method of saturation phenol and chloroform and we amplified the ACE gene using the DNA polymerase chain reaction technique.The amplification products were employed electrohoresis in 2% sepharose.the polymorphism of the angiotensin converting enzyme gene was analyzed under ultraviolet lump.Results In the obser-(ving) group,the genotype distribution frequency of the ACE was II in 12(17.65%),DD in 32(47.06%) and ID in 24(35.29%),and in the control group,it was II in 20(31.25%),DD in 10(15.63%) and ID in 34(53.12%).Conclusions The study result clarifies that CHD has close correlation to the polymorphism of the angiotensin converting enzyme gene.The relative risk of DD genotype is higher than that of the others,and DD genotype possibly is the predisposing genotype of CHD D allele perhaps is the susceptibility gene of CHD.

Objective To describe nursing assistants' experience of caring for dementia patients with behavioral symptoms.Methods A descriptive qualitative design was used in this study.Twelve nursing assistants for dementia patients were recruited.A semi-structured interview was used to collect the data.The interview was related to nursing assistants' experience of caring for patients with behavioral symptoms.Content analysis was used to explicate the meaning of the interview data.Results Three themes were extracted:having multiple stressors; learning by practice; seeking mutual support from other nursing assistants.Conclusions Nursing assistants had multiple stressors from caring dementia patients with behavioral symptoms.Continuing supply of training on strategies of coping with behavioral symptoms as well as the emotional support are especially required.

OBJECTIVE: To establish a method of molecular biology to identify the authenticity and varieties of Penis et Testis Cervi rapidly, simply and accurately. METHODS: The mitochondrial DNAs (mtDNA) of dried Cervus nippon Penis, Cervus elaphus. L Penis, Penis et Testis Bovis and commercial products were extracted and purified with column chromatography. A pair of primers were designed for PCR special amplification of mtDNA according to cytochrome b gene sequence in the cervidae mtDNA GenBank; the products of PCR were analyzed for the single strand conformation polymorphism (SSCP) by denaturing polyacrylamide gel electrophoresis (PAGE). RESULTS: The positive control samples and some commercial products showed clear single strand DNA (ssDNA) bands with different mobility, but the negative control sample and some other commercial products showed nothing. CONCLUSION: Column chromatography method is a good way for getting mtDNA with high purity and less destruction of structure for the follow-up special PCR amplification; SSCP technique not only shows ssDNA bands of mutually complementing clearly, but also reveals the difference of mobility among ssDNAs from all samples directly. For that reason, the technique of PCR-SSCP will be reliable and feasible to indentify the authenticity and varieties of products from cervidae.

Objective To study the value of upbuilding heartcare network in metabolic syndrome.Methods Body mass index,waist and breech circumference,waist hip ratio,blood pressure,fasting plasma glucose,lipid profile, plasma insulin,and urine albumin were determined.Various risk factors were assessed and intervention measures were made.Results Various risk factors in metabolic syndrome were decreased after treatment intervention for 3,6 months,1 and 2 years.Conclusion Taking integrated intervention measures with heartcarc network was significant for hygiene.

With the development of society, people request the doctors higher and higher, which advances a new project for cultivating the doctors in new century. In order to provide the basis for confirming the medical talent cultivating target of new century, we have finished the research on the request to the doctors in new century, and the purpose is to make our medical colleges cultivate more medical talents to meet the need of the 21st century.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

Introduction of clinical cases to experiment teaching of pharmacology is an effective method,which combines basic theory with clinical medicine.It can stimulate students' interest in pharmacology,enhance their go-aheadism in study and also improve teaching effects.Moreover,it plays an important role in improving the students qualities such as the reasoning ability,the verbal capacity and the ability to analve and resolve problems,etc..In this article,we explored the teaching method in experiment teaching of pharmacology,and evaluated the effect by questionnaire.

Objective To study the solute clearance effect of the new concentrated anticoagulation hemodiaiysate of citrate for hemodialysis in patients with high risk of bleeding. Methods Forty-two kidney failure patients with high risk of bleeding were divided into two groups (Group A and Group B) according to their hemodialysis manners. Patients in Group A were hemodialyzed with bicarbonate hemodialysate with low-molecular-weight heparin (dalteparin) anticoognlation and those in Group B with the new citrate antieoagnlation hemodialysate prepared in our hospital without any other anticoagulant. Blood urea nitrogen (BUN) and creatinine (Cr) concentrations were measured before and after dialysis, and Kt/V and urea reduction rate (URR) were calculated. In addition, activated clotting time (ACT) and ionized calcium (iCa2+) concentration were also measured at the arterial and venous ends. Results ACT was extended and iCa2+ concentration decreased significantly at the venous end compared with those at the arterial end in Group B (P<0.01). BUN and Cr concentrations were markedly decreased after dialysis compared with those before dialysis in both groups (P<0.01), and no significant difference in solute clearance effect, as indicated by Kt/V and URR, was observed between Group A and Group B (P>0.05). Conclusion The solute clearance effect of the new concentrated anticoagnlation hemodialysate of citrate is excellent during hemodiaiysis in kidney failure patients with high risk of bleeding.

Objective To evaluate the effect s of Ginkgo Leaf Extract and diphyridamole injection on patient s with CKD.Methods 60 patients with CKD were made up with 36 cases in Ⅲ phase and 24 cases in Ⅳ phase.The patients with CKD were given Ginkgo Leaf Extract and diphyridamole injection,20 mL/d,for 15 days.The parameters of clini- cal condition,function of kidney,ALB and blood fat were observed before and after the therapy and the data were ana- lyzed.Results There were 28 cases that clinical condition was better; 24cases no difference; and 8 cases worse.The level of TC and TG were significantly decreased after the therapy,as well as the uric protein quality of 24 hours(P0.05). Conclusion Essential treatment for CKD combined with Ginkgo Leaf Extract and diphyridamole injection can improve nutrition,delay the process of CKD and protect the renal function in patient s with Ⅲ phase.
