Objective To explore the effect of chromosomal abnormality and polygenic inheritance factor in female children with short stature.Methods 1.Chromosome analysis:peripheral blood was drawn for 1 mL and cultured 72 h to analyze chromosome karyotype (Giemsa Banding ) of peripheral lymphocytes.2.Polygenic factor analysis:the children′s final height were estimated based on their parents average height,and analyzed the distribution characteristics of children′s final height and compared the estimate final height with the actual height.Results Eighty-three cases out of the 364 female children with short stature were chromosomal abnormality(22.80%).Among the 83 cases,the 45,XO and 46,X,i(Xq) occupied 70%.The distribution of children target height shifted left,and the target height of 76 cases was lower than 2 standard deviation (-2 s)and the consistency of target height and actual height reached 20.88%.The target height of 7 cases was lower than 2 standard deviation in those whose chromosome turned out to be abnormal,and the consistency of target height and actual height was 8.43%.Conclusions Chromosomal abnormality is one of the most important etiologic agents causing short stature in female children, and polygenic inheritance is another important etiologic agent.

Objective: To study the pharmacological action of Mahuang Compound Capsule(MCC) (Herba Ephedrae, Semen Armeniacae Amarum, Fructus Schisandrae, etc.). Methods: The study was carried out through the observation of ammonia induced cough model in mice and acrolein induced cough model in guinea pigs treated with MCC, its effects on asthma model of guinea pigs induced by histamine and acetylcholine mixture and on isolated tracheas smooth muscle of guinea pigs were also studied. Results: MCC administrated orally showed significant antitussive effect in ammonia induced cough model in mice and acrolein induced cough model in guinea pigs. MCC could effectively prevent guinea pigs from asthma induced by histamine and acetylcholine mixture. The water extracts could antagonize histamin phosphate that contract the isolated tracheas of guinea pigs. Conclusions: MCC has antitussive and anti asthma effects.

OBJECTIVETo explore possible relationship between copy-number variations (CNVs) in 15q11-13, 16p11 and SHANK3 gene by using multiplex ligation-dependent probe amplification (MLPA) and the phenotypes in children with autism and to further explore the clinical application of MLPA to make an etiological diagnosis of Autism.
METHODSThe diagnosed of autism was made according to the criteria of the ICD-10 and DSM-IV, with typical cluster of symptoms comprise social disability, communication impairments and repetitious behaviors. MLPA KIT P343-C1 AUTISM-1 was used to detect and describe the incidence of CNVs in these three domains.
RESULTSAmong 109 cases collected from 102 autistic pedigrees, 2 individuals had SHANK3 microdeletion, accounting for approximately 2% (2/109) of cases, suggesting the proportion of SHANK3 microdeletion might contribute to typical autism. The phenotypic traits of patients with SHANK3 microdeletions showed homogenicity in severe core symptoms and mental retardation.
CONCLUSIONSSHANK3 microdeletion is an important genetics component for autism, which may explain 2% typical autism cases. SHANK3 microdeletion might explain autistic core symptoms and mental retardation. MLPA is a sensitive and a high throughput technique to detect CNVs in specific DNA segments, which is beneficial for further investigation of etiology of autism.

OBJECTIVETo determine the prevalence of depression among cancer patients and its influencing factors.
METHODSWe investigated 7967 cancer patients who lived in communities with cluster sampling based on 'Shanghai Cancer Patient Database'. They were investigated through questionnaires and completed the Zung Self-rating Scale. 6694 questionnaires were identified as 'qualified'. We calculated the prevalence of depression and determined the factors with logistic regression model.
RESULTSThe prevalence rate of depression among cancer patients in communities was 24.74% (95% CI: 23.71% - 25.79%). Results from multi-factor analysis showed that duration since diagnosis, stages at diagnosis, metastasis, therapeutics, KPS scores, and pain VAS scores were the important factors.
CONCLUSIONEarly detection, improving the curative effect and providing community health services could reduce the prevalence of depression.

Mongolian folk medicine, the important part of Mongolian medicine, is the main means, method and weapon of disease prevention, treatment and health care. Mongolian materia medicas are the important literatures of guiding the healthy development of the modern Mongolian medicine with a long and dazzling history. Since the founding of new China, a new history chapter of Mongolian folk medicine was opened under the attention and support from all levels of party and government. This paper intends to provide comprehensive insight into the rapid development of Mongolian folk medicine. The resources, phytochemistry, quality standard, pharmacology, dosage forms reform and production were reviewed to expound the process that Mongolian folk medicine was developed from traditional practices to scientific development

Objective To explore the in vivo exposure levels of cigarette smoking ( CS) by measuring the biomar-kers nicotine and cotinine. Methods One hundred and sixty male SD rats were divided into 15 cigarette exposure groups (10, 20 and 30 nonfilter cigarettes/day, for 2, 4, 6, 8 and 12 weeks) and a control group (without CS exposure). The rats were sacrificed at different time?points. The concentration of plasma nicotine and cotinine were measured by GC?MS/MS. Results The CS?exposed rats displayed decreased locomotor activity, ataxic gait, irregular respiration, nasal noise, and salivation after smoking exposure for 3 weeks. Rats in the CS exposure groups had lower body weight, and the reduction of body weight was time and dose related (P<0. 01). The retention time of nicotine was 7. 5 to 8. 5 min. The concentra?tion of plasma nicotine in the CS exposure groups was higher than control group (155 ± 56. 65) ng/mL. The retention time of cotinine was 11. 5 to 12. 5 min, the concentrations of plasma cotinine in CS exposure groups were higher than control group (340 ± 41. 97) ng/mL, the increase of plasma cotinine in CS groups was time?related (P<0. 05), and the exposure concentration and duration had synergistic effect on the level of plasma cotinine ( P<0. 05 ) . Conclusions CS exposurecauses structural damages in male rats. The plasma concentration of cotinine can effectively reflect the in vivo exposure lev?els of cigarette smoking, and well presents a dose?response relationship.

OBJECTIVETo investigate the role of caveolin-1 down-regulation in human hepatocyte proliferation in vitro.
METHODSThe expression vector psiRNA-CAV1 was constructed and transfected into Chang liver cells (CHL). The caveolin-1 down-regulated cell clones were selected by the antibiotic zeocin. The proliferation of the cell strain CAV7 was examined by MTT, in which untransfected CHL and HepG2 cells were set as controls. Expression of caveolin-1, Akt, Erk1/2, p-Akt and p-Erk1/2 in the transfected and control cells was detected by Western blot.
RESULTSAfter caveolin-1 expression was down-regulated by RNAi, CHL increased faster at first (24 h and 72 h, P<0.05; 96 h, P<0.01), but slower later. P-Akt and p-Erk1/2 expressions were down-regulated, indicating that the growth and proliferation related Akt and Erk1/2 pathways were inhibited after caveolin-1 down-regulation.
CONCLUSIONCaveolin-1 may play an important role in hepatocyte proliferation.

Objective:To construct His-tagged peptide of human STAT4 (565-748 amino acid) expression vector and induce its expression in Escherichia coli,followed by purification.Methods:STAT4 gene fragment encoding C-terminal peptide of 565-748 amino acid was amplified by PCR using pEGFP-STAT4 as the template.The PCR product was inserted into prokaryotic expression vector pET-28a and was transformed into component E.coli BL21 cells.By isopropyl-β-D-thiogalactoside(IPTG) induction,fusion protein was found to be expressed in the inclusion body and was denatured by using the urea denaturation buffer followed by renaturation and purifi-cation.Finally the purified protein was confirmed by Western blot.Results:The STAT4 truncated gene encoding 565-748 amino acids peptide was amplified by PCR and inserted into pET-28a vector.After the recombined plasmid was transformed into component BL21, the His-tagged-STAT4 (565-748 amino acids) fusion protein was induced and obtained after denaturation,refolding,purification and dialysis.Conclusion:The eukaryotic expression vector containing the truncated human STAT4 gene encoding 565-748aa peptide has been successfully constructed and the fusion protein was obtained.
