Objective To investigate the changes in the expression of GABAAα1, receptors in medial prefrontal cortex (mPFC) in a rat model of neuropathic pain. Methods Nine male Wistar rats weighing 200-210 g were randomly divided into 3 groups ( n = 3 each): control group (group C) , sham operation group (group S) and neuropathic pain group (group P). Neuropathic pain was induced by chronic constrictive injury. The right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 3-0 chromic catgut. In group S, the right sciatic nerve was exposed but not ligated. The thermal and mechanical pain threshold was measured at 1 d before and 1,4,7, 10 and 14 d after operation. The animals were then sacrificed and the mPFC was removed. The expression of GABAAα1, receptors in mPFC was determined by Western blot. Results Compared with C and S groups, thermal and mechanical pain threshold were significantly decreased and the expression of GABAAα1, receptors was up-regulated in group P ( P ＜ 0.01) . There was no significant difference was in the thermal and mechanical pain threshold and expression of GABAAα1 receptors between C and S groups (P ＞ 0.05). Conclusion Up-regulation of GABAAα1 receptor expression in mPFC may be involved in the development and maintenance of neuropathic pain in rats.

OBJECTIVE: To determine the allelic frequency distribution and genetic parameters of nine non-CODIS DNA index systems of the short tandem repeat (STR) loci (D2S1772, D6S1043, D7S3048, D8S1132, D11S2368, D12S391, D13S325, D18S1364, and GATA198B05). METHODS: A total of 353 blood samples were collected, extracted, amplified, and analyzed from unrelated healthy individuals of Han nationality in Hunan Province, China. RESULTS: One hundred and fourteen alleles were observed in the population with corresponding allelic frequencies ranged from 0.001 0 to 0.323 0. For all the nine non-CODIS STR loci, the observed genotypic data showed no significant deviations from the Hardy-Weinberg equilibrium. The Ho, He, PIC, DP, and PE of the studied non-CODIS STR loci ranged from 0.1080 to 0.1950, 0.8050 to 0.8920, 0.7700 to 0.8600, 0.9250 to 0.9660 and 0.6070 to 0.7800, respectively. CONCLUSION Nine non-CODIS STR loci have high degrees of polymorphisms, which may be useful in individual forensic identification and parentage testing in forensic practice.

Microbial contamination, growth and reproduction have a great influence on the quality of traditional Chinese medicine (TCM) and its preparation. TCM may be polluted by microbial in the production process due to ambient air, facilities and appliances and operating personnel, which affects the quality and efficacy of the final product. The GMP certification inspection standard of TCM manufacturing enterprises clearly established: "Sterilization methods of Chinese herbal medicine, intermediate products, finished products should follow the principle whether or not to change its quality", "TCM powder that used as medicine directly should follow the principle whether to do microbiological examinations". So it's particularly important for product quality, corporate energy consumption and its efficiency to choose the scientific and effective sterilization techniques and methods. Ozone is a kind of safe, environmentally friendly, efficient and no residue emerging sterilization technology. It has been widely applied in various fields of medical and health care and production and living. This paper mainly analyzed the ozone sterilization technology of TCM, aiming to explore the principle of ozone sterilization, the advantages, application status and existing problems and so on. The management regulations and implementation rules of ozone sterilization were summarized to make sterilization of Chinese medicine in the production, management, quality control and other aspects standardized, reasonable and scientific, and to provide the theoretical reference of the ozone sterilization technology for TCM and its preparation.

Objective To explore the changes of tumor necrosis factor-?(TNF-?) in serum and cerebrospinal fluid(CSF) of children with acute lymphoblastic leukemia (ALL) and acute myelogenous leukemia(AML) and its clinical significance.Methods TNF-? in serum and CSF were measured by radioimmunoassay and CSF samples were obtained from 31 cases of childhood acute leukemia before treatment, on complete remission(CR), and continuous CR.Results Serum TNF-? was in ALL and AML before treatment [(24.35?4.84) pmol/L and(28.65?5.12) pmol/ L],which were significantly higher than those of healthy controls[(11.2 8? 1.69) pmol/L, P

Objective To observe toxic effect of deoxynivalenol(DON)on articular cartilage and synovium of New Zealand rabbits's knee ioints.Methods Fifteen male rabbits were divided randomly into 3 groups:control, high-dosage,and low-dosage group.In high-dosage and low-dosage group,saline solution of DON was injected with a dose of 0.10 and 0.05 ms/kg every 48 h into ear vein of rabbits.Specimen of articular cartilage and synovium were through pathologY methods,and IL-1β,TNF-α,NO levels were assayed in joint liquid,after 20 days. Results Morphological changes were observed, such as synovium inflammative infiltration, chondrocytes deformation and necrosis under light microscope.The levels of IL-1β,TNF-α and NO had statistical significance in comDarison between 3 grouPs(F=19.396,18.195,22.136,P＜0.05).The levels of IL-1β,TNF-α and NO were significantly higher(all P＜0.05),high-dosage[(0.451±0.091),(0.575±0.122)μg/L;(70.27±11.53)μmol/L] and low-dosage group[(0.295±0.107),(0.387±0.131)μg/L;(45.32±12.24)μmol/L]compared with control ((0.1 13±0.049),(0.138±0.087)μg/L;(23.56±9.35)μmoL/L],and high-dosage compared with low-dosage group Conclusions DON results in articular and synovial impairment,which has the symptom similar to osteoarthritis. DON probably causes osteoarthritis.

OBJECTIVETo study the risk factors and abusers' characteristics on childhood sexual abuses among female students to provide reference data for preventive measures on child sexual abuse.

METHODSAnnonymous questionnaire survey of 701 adult female students in a college about their personal experience on childhood sexual abuses, their home conditions and abusers' characteristics.

RESULTSA total number of 701 female students were surveyed. 115 (22.11%) experienced non-physical contact sexual abuses before the age of 18, including 26 (3.71%) who suffered from attempted and 8 (1.14%) were forced with genital or anal sexual intercourse. 117 (16.69%) said they had suffered from sexual abuse before the age of 16. Most abusers were males (99.4%) and only a small percentage of them (3.2%) used violence. Most non-physical contact sexual abuses were from strangers (78.7%), while 71.3% of physical contact abuses were from acquaintances including 12.5% of them were teachers, 17.5% were neighbors and 21.3% were relatives. The risk factors of child sexual abuses were: frequent use of violence, bad hobbies and poor health conditions of parents, tight family relationships, and living in remarried families. Having well-educated fathers was a preventive factor.

CONCLUSIONStudies on childhood sexual abuses among females revealed that the incidents were not rare, and family environment played an important role.
