Objective To explore correlation of Xinjiang Kazakh population who suffered from COPD with polymor?phisms of F+1,S2,T1,ST+5 locus of ADAM33 gene. Methods Blood samples (n=193) from healthy controls (Control group, n=193) and COPD patients (Case group, n=197) were detected by SNP SNaP shot. Results Comparing case group with the control group, gene frequency and allele frequency of F+1 locus were of significant differences (P<0.05). In patient group, there were no significant differences in F+1 locus genotype and in clinical indicators include lung function FEV1 predicted and FEV1/FVC (P>0.05). The gene frequencies and allele frequency of S2、T1 and ST+5 locus were not significantly differ?ent between case group and control group (P>0.05). F+1 and S2 locus were analyzed by haplotype analysis which showed that there was significant differences in Hap1 (CC) haplotype between case group and control group (P<0.05), and OR<1 indicated that its haplotype may reduce the risk of COPD . There were significant differences (P<0.05) in Hap3(TC) haplo?type between case group and control group and OR>1 revealed that its haplotype may increase the risk of COPD . The distri?bution of Hap2 (TG) and Hap4 (CG) were not significantly different (P>0.05) between the 2 groups. T1 and ST+5 locus were analyzed by haplotype analysis which showed significant differences in haplotypes between case group and control group (P<0.05). Conclusion The occurrence of COPD may be related to the polymorphism of ADAM33 gene in F+1 locus in Xinjiang Kazakh.

OBJECTIVE: To investigate the inhibition effects of Tianshen Yizhi Recipe (TSYZR), a compound traditional Chinese herbal medicine, on decreased expression of nicotinic acetylcholine receptor (nAChR) and the neurotoxicity as well as lipid peroxidation induced by beta-amyloid peptide (Abeta) in human SH-SY5Y neuroblastoma cells. METHODS: The SH-SY5Y cells were treated by a certain concentration of TSYZR, and then exposed to Abeta(25-35). Methyl thiazolyl tetrazolium reduction assay was carried out to understand the influences of the drugs on cellular viability. Expressions of nAChR subunits (alpha3 and alpha7) at protein and mRNA levels were detected by Western-blotting and reverse transcription polymerase chain reaction, respectively. Lipid peroxidation was measured by thiobarbituric acid to observe the capacity of antioxidant of the drugs. RESULTS: TSYZR at a safe concentration could increase alpha7 protein in the cells, inhibit decreased expressions of alpha3 and alpha7 nAChR subunit proteins, prevent lower expression of alpha7 mRNA in SH-SY5Y cells induced by Abeta, reduce the neurotoxicity and lipid peroxidation resulting from Abeta, but had no significant effect on the lower expression of alpha3 mRNA. CONCLUSIONS: TSYZR can up-regulate the expression of alpha7 nAChR subunit protein and prevent decreased expressions of nAChRs and neurotoxicity as well as lipid peroxidation induced by Abeta. This drug may play an important therapeutic role in treatment of Alzheimer disease.

Objective:To investigate the association between polymorphisms of FGFR2 and the susceptibility of breast cancer in Han population in Guizhou province.Methods:Genotyping was performed using PCR-sequence-specific primers(PCR-SSP)in 106 histologically confirmed breast cancer cases and 116 cancer-free controls.Results:The genotype frequencies of rs1219648 TT,TC,and CC were 50%,25.47%.and 24.53% in breast cancer cases and 29.31%,48.28%,and 22.41% in the controls.The gene frequencies of T in breast cancer cases and the controls were 62.74% and 53.45%.respectively.The gene frequencies of C were 37.26% and 46.55%.respectively.The distribution of allele and genotype frequencies of FGFR2 rs1219648 was statistically different between breast cancer cases and the controls(P<0.05).Conclusion:FGFR2 rs1219648 polymorphism influences the susceptibility of breast cancer.TT genotype might serve as a risk factor for breast cancer.

OBJECTIVE:To interpret the record of set prescription preparations containing Panax ginseng in 2015 edition of Chinese Pharmacopoeia (part Ⅰ),and to provide reference for the future research and new drug development of P ginseng.METHODS:The set prescription preparations containing P.ginseng in 2015 edition of Chinese Pharmacopoeia (part Ⅰ) were collected to classify and analyze the selection,dosage form,preparation method,functions of curing and precautions,etc.RESULTS & CONCLUSIONS:In 2015 edition of Chinese Pharmacopoeia (part Ⅰ),there were 116 kinds of set prescription preparations containing P.ginseng,P ginseng and Radix Ginseng Rubm were the mainly selected,and combined with other Ginseng.The ingredients of set prescription preparations were mainly below fifteen ingredients;dosage forms were mainly pills (34 kinds) and capsules (28 kinds);oral administration was used as the main usage (114 kinds);main preparation method was that P ginseng was smashed into fine powder and used directly as medicine (68 kinds);the functions of curing included tonifying qi-blood,nourishing yin and tonifying kidney,clearing heat and resolving phlegm,nourishing lung and nourishing heart.In the future research,researchers will explore other effects of P.ginseng or P.ginseng combined with other drugs,and develop new drugs containing P.ginseng according to set prescription preparations containing P.ginseng in 2015 edition of Chinese Pharmacopoeia (part Ⅰ).

OBJECTIVETo analyze the genetic susceptibility of HLA-DQA1 allele to anaphylactoid purpura(AP)and its association with the clinical features in juvenile Hans residing in Inner Mongolia.

METHODSSeventy children with AP and ninety normal controls of Hans in Inner Mongolia were subjected to HLA-DQA1 genotyping with the use of polymerase chain reaction-sequence specific primer (PCR-SSP) technique.

RESULTS(1) The gene frequency of HLA-DQA1*0301 of AP group (33.4%) was significantly higher than that (10.6%) of control group (chi square=21.899, P<0.01). On the other hand, the gene frequencies of HLA-DQA1*0302 were 6.7% and 19% in the AP group and the control group respectively; a significant difference between them was seen (chi square=9.786, P<0.01); (2)The gene frequencies of both DQA1*0301 and DQA1*0302 in the cutaneous purpura simplex cases and the controls were not significantly different (P>0.05). The gene frequencies of DQA1*0301 of the cutaneous purpura cases associated with gastrointestinal, joint and renal impairment were 26.7%, 28.5% and 29.3% respectively, which were higher than that of the control group (10.6%); the differences were statistically significant (P<0.01, 0.01, 0.01; respectively). The gene frequencies of HLA-DQA1*0302(3.9%, 5.7% and 9.6%) for the cutaneous purpura cases associated with gastrointestinal, joint and renal impairment were significantly lower than that (19%) of the controls except renal impairment(P<0.01, 0.01, respectively).

CONCLUSIONThe allele of HLA-DQA1*0301 was probably a susceptible gene while HLA-DQA1*0302 was the protective one in AP of the children who were Han inhabitants in Inner Mongolia. The results of this study also revealed that patients with the allele of HLA-DQA1*0301 tended to involve gastrointestinal, joint and renal impairment.
