Objective To evaluate the efficacy of laparoscopic ovarian drilling for treating clomiphene-resistant polycystic ovary syndrome(PCOS).Methods Laparoscopic ovarian drilling,with pelvic adhesion release and salpingoplasty,was performed in 38 cases of clomipheneresistant PCOS from March 2001 to May 2005 in this hospital.Serum concentrations of luteinizing hormone(LH),follicle-stimulating hormone(FSH),androgen(T),and estradiol(E2) were measured before and after operation.Ovarian follicular development,pregnancy rate,and abortion rate were observed after operation. Results Postoperatively,there was a significant decline of levels of LH(from 22.36?3.17 U/L to 8.73?1.95 U/L;t=3.13,P

Objective In this study,we aimed at investigating the clinical,laboratory and management characteristics of adolescent-onset SLE patients compared with adult-onset SLE patients.Methods 470 fe- male patients with SLE were divided into two subgroups:adolescent-onset SLE patients and adult-onset SLE patients.The analyzed variables included clinical,laboratory parameters,damage index and outcome charac- teristics.Results In 470 female patients with SLE,there were 98(20.85%)adolescent-onset SLE patients. The following manifestations occurred more frequently in adolescent-onset SLE patients:malar rash,cutaneous vasculitis,proteinuria and abnormal liver function.Adolescent-onset SLE patients had more severe disease features and had significantly higher mean value of SLEDAI.Mortality was higher in adolescent-onset SLE pa- tients than aduh-onset SLE patients.Renal and blood system were the organs that most frequently involved. Conclusion Adolescent-onset SLE patients accounts for roughly 20.85% of all SLE cases.It is necessary to pay more attention to adolescent-onset SLE patients because the management for them is usually more difficult and the prognosis is usually poorer than aduh-onset SLE patients.

Objective To evaluate the effect of peer educatio n program by the application of the peer education on human immunodeficiency vir us/aeguired immune deficiency syndrome(HIV/AIDS) prevention and the analysis of the change on knowledge, attitude and behavior about HIV/AIDS among technical sc hool students in Shanghai. Methods Three technical schools in Shanghai were selected randomly. Two classes of each school were selected randomly as education group and the students added up to 284.Two hundred and sixty-one students of another 2 classes in each school were selected as the interior control group. Some freshmen came from medical un iversity were carefully trained as peer educators to conduct the education inclu ding 6 models. The same questionnaires were carried before and after the educati on in both groups. Results After peer education the score of average knowledge abo ut reproductive health, HIV/AIDS, STD was significantly higher than before (P 0.05). Conclusions The conduction of the peer education on HIV/AIDS pr evention among technical school students is effective in promoting the knowledge level,but the change of attitude and behavior is a long term. So we highly adv ocate that not only the health education for HIV/AIDS especially safe sex shall be given and strengthened among technical school students in order to promote t he notion of self-protection but also the conception of care others especially t he HIV/AIDS.

NAC transcription factors involved in plant growth and development, as well as responses to biotic and abiotic stress. RNAi Vectors for SmNAC transcription factors of Salvia miltiorrhiza was constructed by using Gateway cloning technology, in order to further study the function of SmNAC1 transcription factor. According to Gateway cloning technology, the specific fragments of SmNAC1 containing attB adapter was amplified by PCR using ultra-fideling phusion polymerase of NEB. By the BP recombination reaction, the PCR product containing attB was transferred to an donor vector (pENTR/SD/D-TOPO). Finally, SmNACi specific gene was cloned into pK7GWIWG2D plant expression vectors by LR recombination reaction. Experimental results showed that Gateway cloning technology provide a rapid and highly efficient way to clone the interested gene.

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, a full-length cDNA sequence of SQS2 from S. miltiorrhiza f. alba was cloned by the method of reverse transcription polymerase chain reaction (RT-PCR). The SmSQS2 cDNA sequence was obtained, this sequence is named SmSQS2 and its GenBank registration number is KM244731. The full length of SmSQS2 cDNA was 1245 bp, encoding 414 amino acids including 5'UTR 115 bp and 3'UTR 237 bp. Sequence alignment and phylogenetic analysis demonstrated that SmSQS2 had relative close relationship to the SQS2 of S. miltiorrhiza. The induction of E. coli [pET28-SQS2] in different temperature, induction time, IPTG concentrations and density of inducing host bacterium (A600) were performed, Shaking the culture at 30 degrees C until the A600 is approximately 0.6 and add IPTG to final concentration of 0.2 mmol x L(-1), and then the optimal expression of SmSQS2 recombinant protein were accumulated after the induction time of 20 h. The research provided important base for the study of sterol and terpene biosynthesis of SQS2 in S. miltiorrhiza f. alba.
