Objective To investigate the effects of Chinese drugs for nourishing Yin and clearing the heat on regulation of sex hormones and clinical efficacy patients with SLE.Methods Fifty four active SLE patients with Yin deficiency were randomly divided into 2groups.Thirty patients in tr eatment group were treated with Pill of Wind-weed Phellodendron and Rehman nia(Zhibai Dihuang Wan)and Bolus for Replenishing Vital Ess ence(Da Buyin Wan)combined with western medicine for 2months,while 24patients in control group were treated with western medicine alone.Before and a fter treatment,the serum levels of f ollicle-stimulating hormone(FSH),luteinizing hormone,estradiol,pr ogesterone,testosterone,prolactin were measured by ELISA in 54patien ts,respec-tively.Before treatment the serum l evels of FSH,luteinizing hormone,estradiol,progesterone,testosterone,prolactin were measured in 30active SLEpatien ts without Yin deficiency and 25age-matched healthy controls simultaneously.Results The mean levels of FSH,luteinizing h ormone,estradiol were significant ly higher in patients with Yin de-ficiency than those without Yin deficiency and those in heathy controls(P

Objective To investigate the risk factors of flare in systemic lupus erythematosus(SLE).Methods In this retrospective cohort study132cases of SLE were followed up for1～5years.The risk factors of SLE flare were analyzed by univariate and multivariate logistic regression with computer software,SPSS.Results Of the132patients,82cases had more than one flare,the total number of flares was115.The incidence of flare was0.22per patient-year.The frequency of flares within5years after diagnosis of SLE was higher than that in more than5years.By univariate logistic regression analysis the age younger than40years at the beginning of the study,age of disease onset younger than32years,stress,depression,overwork,pregnancy,suffering from infectious disease,and quick decreasing of prednisone dosage significantly increased the risk of flare(P

BACKGROUND: Nowadays, fish collagen biomedical materials still exhibit obvious deficiency in thermal stability,in vivo degradation stability and in vivo material morphology stability. To expand the application of fish source collagen, it is urgent to improve the material performance by increasing the density and collagen molecule tightness of freshwater fish collagen sponge materials using technique methods.OBJECTIVE: To optimize the reconstitute process for nasopore preparation using fish scale collagen.METHODS: The optimal process for nasopore preparation through the reconstitution of fish scale collagen was ascertained by taking tilapia fish skin as a raw material to extract enzymatic soluble collagen at a temperature lower than the collagen denaturation temperature and recombinant rate of collagen fibers as index. Optimization of the conditions for nasopore preparation was carried out using single factor test and orthogonal test. The prepared nasopore was analyzed through infrared spectroscopy and microstructure analysis.RESULTS AND CONCLUSION: The optimal conditions for nasopore preparation were determined through the single factor test and orthogonal test as follows: 20 ℃ for 10 hours at pH 7.4 using a mixture of 65 mmol/L NaCl and 1 g/L collagen, by which the reconstitute rate of collagen fibers was up to 68.6%. The prepared nasopore is characterized by a refined porous structure constituted by threadlike collagen fibers, and has complete three-dimensional spiral structure,which is a potential intracavitary hemostatic material with fine properties.

Objective To make clear the clinical safety of ultrasound guided percutaneous 125I radioactive seed interstitial implantation for treatment of pancreatic cancer.Methods 92 cases of pancreatic cancer treated with ultrasound guided percutaneous 125I radioactive seed interstitial implantation were retrospectively ana lyzed.Results All the 92 cases were performed successfully according to the preoperative plan.25 cases suffered puncture-hemorrhage and blood loss about 2 to 20 ml,and all got hemostasis successfully.2 cases had pancreatic duct injury during puncture,but no pancreatic fistula was found after conservative treatment.No case had bile duct injury.No digestive tract perforation occurred in the 55 cases whose puncture path was through the gastrointestinal tract.No serious complications occurred during the surgery.Conclusions Ultrasound guided percutaneous 125I radioactive seed interstitial implantation for treatment of pancreatic cancer is safe and reliable.

Objective:To explore the sexual behavior of high school students of Beijing and its relationship to parent and peer attachment.Methods:847 students of two high schools in Beijing were investigated with self-designed inventory on sexual behavior and Inventory of Parental and Peer Attachment.Results:The age of first menstruation among girl was 12.7,that of first semen loss of boys was 13.2.3.3% students had sex intercourse(in boys 16/350,in girls 12/497),the average age of them was 16.0.39.1% students had dating experience.The source of sex information came mainly from friends(38.8%),books and newspaper(24.5%),and school education(15.8%).Boys had more positive attitude to sex behavior of peers than girls.Students with safe attachment to parents were more conservative to sex behavior than those with unsafe attachment to parents.They also had less sexual behaviors.Conclusion:Sex behavior and attitude of high school students in Beijing have week association with attachment pattern.

Objective To identify the effect of low salt medium on P44/42 kinase(ERK)、AP-1 in the expression of cyclooxygenase-2 (COX-2) in a mouse macula densa derived cell line (MMDD1 cells). Methods MMDD1 cells were transfected with luciferase reporter plasmid containing AP-1. Luciferase reporter assay were studied in normal salt(NS) and low salt(LS) medium; the expression of C-JUN、C-FOS were analyzed as well by Western Blotting. RT-PCR and Western Blotting were used to detect the mRNA and protein expression of COX-2. Expression of total and phosphorylated ERK was analyzed by Western Blotting in LS solution. The content of PGE2 in the supernatant was examined by ELISA. Results Phosphorylated ERK were markedly increased by LS treatment. The up-regulated COX-2 protein expression with LS was reduced with PD-98059 (ERK inhibitiors) at 20 ?mmol/L, PGE2 release was down-regulated as well. Luciferase activity of AP-1 was stimulated in LS, the up-regulated luciferase activity of AP-1 was attenuated by curcumin at 20 ?mmol/L (AP-1 inhibitor). The expression of C-JUN、C-FOS were increased as well. Low salt medium changed COX-2 mRNA abundance and protein expression was decreasedin medium with curcumin at 20 ?mmol/L.Conclusion Low salt induces the expression of COX-2 in MMDD1 cells through the activation of ERK、AP-1 pathways.

objective To clarify the significance and puncture path of 125I radioactive seeds implantation in treatment of postoperative local recurrence and pelvic metastasis in patients with rectal cancer.Methods Clinical data of 8 rectal cancer patients with postoperative local recurrence and pelvic metastasis treated by ultrasound guided 125I radioactive seed implantation were retrospectively analyzed and the therapeutic effects were observed.Results After the treatment,the symptoms of 5 cases suffering from hematochezia and 2 cases with vaginal bleeding disappeared within 21 to 30 days.7 patients with preoperative pain relieved after treatment.There was no tumor progression from postoperative imaging examination.Conclusion 125I radioactive seed implantation can effectively improve the life quality of rectal cancer patients with postoperative local recurrence and pelvic metastasis.

ObjectiveTo investigate the clinical efficacy of points Shenmai(BL62)and Zhaohai(KI6)in treating cervical vertigo. MethodSixty-eight patients meeting the diagnostic criteria were randomly allocated to treatment and controlgroups, 34 cases each. The treatment group received conventional acupuncture at heel vessel points Shenmai and Zhaohai plus cervical Huatuo jiaji points and the control group, conventional acupuncture at cervical Huatuo jiaji points alone. In the two groups, the vertigo symptom score was recorded, and the clinical therapeutic effects and pre-/post-treatment change in the score were observed.ResultThe total efficacy rate was 94.1% in the treatment group and 79.4% in the control group. The therapeutic effect was significantly better in the treatment group than in the control group (P<0.05). The vertigo symptom score decreased significantly in the two groups after the course of treatment compared with before (P<0.01). Vertigo improved significantly more inthe treatment group than in the control group (P<0.05).ConclusionAcupuncture at points Shenmai and Zhaohai is significantly effective by comparison with conventional acupuncture in clinicaltreatment of cervical vertigo.
