d, suggesting that the mutation rate of SDHB gene in sporadic Chinese patients with pheochromocytoma might be around 3%.

OBJECTIVETo explore the mechanism of prevention and treatment of post-PTCA restenosis with Xinmaitong (XMT).

METHODSRabbit carotid endothelial injury model was established using Fishman air drying method. Effect of XMT on model rabbits wild-type p53 gene expression was observed by tissue in situ hybridization.

RESULTSp53 gene expression appeared on the 3 days after operation, enhanced on the 7 days, reached the peak on the 14th day, weakened on the 21th, and still showed on the 28th day. The strongest expression was shown in rabbits treated by XMT, second in those treated by Warfarin, and the weakest in the operated control group.

CONCLUSIONXMT could promote the high expression of wild-type p53 gene expression in rabbit with carotid endothelial injury, which is possibly one of the important mechanism of XMT in preventing and treating arterial restenosis.

Objective To study effects of baicalin(Bai) on AngⅡ in diabetic nephropathy(DN) rats and to explore its preventive and therapeutic effect on treating DN from the non-hemodynamic mechanism of AngⅡ.Methods Nineteen specific pathogen-free male rats were randomly divided into three groups:normal control group(5 rats),diabetic nephropathy model control group(7 rats),baicalin treated group(7 rats).DN rat model was established by one-dose intraperitoneal injection of streptozotocin.Seven weeks after the modeling,rats in baicalin group recieved intraperitoneal injection of baicalin solution(40 mg/kg),rats in DN model group received intraperitoneal injection of normal saline(1 mL for each rats),and the normal control group did not receive any intraperitoneal injection.After treatment for 6 weeks,orbital blood from all rats was collected to determine plasma AngⅡ by radioimmunoassay.Unilateral kidney was processed by 4 % paraformaldehyde fixation and then was used for the determination of TGF-? by immunohistochemical assay.The other unilateral kidney was got out to prepare for renal cortex homogenate,and then was used for the determination of renal tissue AngⅡ by radioimmuno assay.Results The quantity and degree of TGF-? expression in baicalin group was decreased,and there was statistical significance between baicalin group and the model group(P

Objective To develop psychosocial skills training module for schizophrenic outpatients.Methods Structured psychosocial skills training program, which were made according to community rehabilitation plan for schizophrenia, featured convenience and well operability. Subjects were 96 of 204 schizorenic outpatients in remission who were randomly assigned to receive psychosocial skills training combined medicine(observation group) or medicine only(control group) and followed up by 24 months. The changes during treatment were evaluated by positive and negative syndrome scale(PANSS), Social Disability Screening Schedule(SDSS) and patients' cognition function were also evaluated longitudinally. Results Relapse rate of control group (37%) is higer than observation group (17.7%, P＜0.01). After Last Observation Carried Forward(LOCF), control group showed higer scores than observation group on positive syndrome (8.34±2.04 vs 7.66±0.97), negative syndrome(9.15±1.97 vs 813±1.15), total score (37.64±5.58 vs 34.79±3.64) and Social disability (2.81±1.90 vs 2.07±1.47) (P＜0.01); observation group also showed a significant progress on cognition function(P＜0.05). Conclusion This trial demonstrated the efficacy of the easy-operating structured psychosocial skill training grogram in preventing relapse and improving social adoptive function for schizophrenia.

Objective To investigate the polymorphism of human cytomegalovius UL143 gene of low passage clinical isolates in Guangzhou,China.Method PCR was performed to amplify the entire HCMV ULl43 gene region of 3 clinical isolates,which had been proven by multiplex PCR.The amplification products were cloned into pMD18-T-Vector and subjected to sequencing.The result of DNA sequences were analyzed together with the one of published homologous sequences in GenBank from 14 clinical isolates.Result There were several stop codons in UL143 gene due to a base deletion in open reading frame (ORF) of D3 isolate,which could lead to produce non-functional protein.UL143 ORF of Toledo isolate consisted of 279 nueleotides,encoding a protein with 92 amino acids.UL143 ORFs of other isolates consisted of 252 nueleotides,encoding a protein with 83 amino acids.The DNA sequences were quite conserved and all the variations were base substitution.The amino acid sequences of different isolates were highly conserved.with variation of 1.2%-2.4%.There were no additional or deleted sites of post translational modification of UL143 protein in all clinical isolates except Toledo isolate.There were some differences in the secondary structure among different isolates.The isoelectric point of UL143 protein of all clinical isolates except Toledo isolate was 8.75.Conclusion All DNA and deduced amino acid sequences of UL143 gene shared great similarity among HCMV clinical strains regardless of their polymorphism.

Objective To evaluate the values of bilateral inferior petrosal sinus sampling ( BIPSS),high dosage dexamethasone suppression test (HDDST) and pituitary image in the differential diagnosis of ACTH-dependent Cushing's syndrome. Methods Totally 87 patients with confirmed pathological diagnosis were recruited in the study.All received the procedure of BLPSS,HDDST,and pituitary MRI with dynamic enhancement.The diagnostic performances of three differential diagnosis methods in ACTH-dependent Cushing's syndrome were evaluated.Results Seventy-eight patients were diagnosed as cases of pituitary ACTH adenoma,and the remaining 9 were confirmed cases of ectopic ACTH syndrome due to the thymic carcinoid.The sensitivity and specificity of HDDST,pituitary MRI,and BIPSS for the diagnosis of ACTH-dependent Cushing's syndrome were 82.1％ and 100％,79.5％ and 44.4％,92.3％ and 100％,respectively.In Cushing's disease,the diagnostic accuracy was 83.9％ with HDDST,77.0％with pituitary MRI,and93.1％ with BIPSS.In those patients with Cushing's disease,the coincidence of lateralization was 83.9％ with BIPSS and 64.5％ with MRII.Conclusion BIPSS was better than the other two methods in differential diagnosis of ACTH-dependent Cushing's syndrome.Compared with the pituitary MRI,the concordant rate of BIPSS in lateralization of the tumor is higher,and it is more reliable.

With DQOL (diabetes quality of life) scale, quality of life was evaluated before and after diabetic education in 136 type 2 diabetic patients. The Cronbach′s ? of DQOL scale was from 0.809 to 0.849, suggesting that the DQOL scale did effectively reflect the life quality of type 2 diabetic patients.

[Summary] All patients with cholesterol side-chain cleavage enzyme ( P450scc) deficiency that have been reported presented with early adrenal failure. Here we described a 35-year-old male presented with infertility as the only initial presenting complaint. He had received two separate surgeries to remove bilateral testicular masses. We reevaluated the resected tumors and found testicular adrenal rest tumor ( TART) pathology in the resected tumor. We profiled steroid hormones and found significantly elevated ACTH. CT scan revealed bilateral adrenal hyperplasia. Mutation screening identified compound heterozygous mutations (R353W and P432L) in the P450scc encoding gene (CYP11A1). The patient was finally diagnosed as congenital adrenal hyperplasia.
