ObjectiveTo investigate the association of HLA-Cw and -DRB1 alleles with psoriasis vulgaris,and to provide a clue to the study into the etiology of psoriasis.MethodsVenous blood samples were obtained from 81 patients with psoriasis vulgaris collected during 2006-2011 at the Department of Dermatology,First Affiliated Hospital of Inner Mongolia Medical College,as well as 100 age- and gender-matched healthy controls.Both the patients and controls are unrelated Mongolia in Inner Mongolia.PCR with sequence-specific primers(PCR-SSP) technique was used to genotype the HLA-Cw and DRB1 loci.ResultsThe patients with psoriasis vulgaris showed a significantly higher frequency of HLA-Cw*06(0.438 vs.0.175,Pc ＜ 0.01) and DRB1*07(0.241 vs.0.110,Pc ＜ 0.012),but a lower frequency of HLA-Cw*04(0.031 vs.0.150,Pc ＜ 0.01 ) and DRB1*04 (0.093 vs.0.235,Pc ＜ 0.01 ) than the healthy controls did.Increased frequencies of HLA-Cw*06 and DRB1*07 alleles were observed in patients with an onset before 40 years of age and those without a family history,together with a decreased frequency of HLA-Cw*04 and DRB1*04 alleles,compared with the healthy controls(Pc ＜ 0.05).The frequency of HLA-Cw*06 allele was significantly higher in patients with a positive family history and patients with an onset of no younger than 40 years of age than in the healthy controls (both Pc ＜ 0.05).ConclusionsHLA-Cw*06 and -DRB1*07 alleles may be susceptibility determinants to psoriasis vulgaris,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis vulgaris,in Mongolia from Inner Mongolia.HLA-DRB1*07 allele may be a susceptibility gene for psoriasis,while HLA-Cw*04 and -DRB1*04 alleles may be protective factors against psoriasis,in patients with an onset before 40 years of age.

Objective To assess the therapeutic effect of esomerphrazole in treating patients with gastroesophageal reflux disease (GRED) between Han and Inner Mongolia populations.Methods Those who underwent endoscopic examination and had reflux disease questionnaire (RDQ) >12 from March 2006 to March 2008 were selected. The patients were divided into Han group and Inner Mongolia group with 120 each. All patients were received esomerphrazole 20 mg daily for 6 weeks. The patients were evaluated by RDQ questionnaire at 2nd, 4th and 6th week, and were reexamined by gastroscopy at 6th week. Results After two weeks, effective rate of 50% was achieved in both groups, but it was higher in Han group than in Inner Mongolia group at 4th and 6th week. After 6 weeks, the curative rate of RE was higher in Han group than in Inner Mongolia group. Conclusion The different nations ancl habits result in the different efficacy of esomerphrazole, which may be improved by prolonging time of medication and changing habits.

Conclusion:The established TLC and HPLC methods are simple and accu-rate with good reproducibility, which can be used in the quality control of Liangxue Shiwei San.

Objective To analyze the effect of five kinds of complicated root canals therapy by utilizing sur- gical microscopes.Methods A total of 359 exactly diagnosed complicated root canals were consecutively treated from July 2003 to December 2004 in department of stomatology,No.4 Affilicated Hospital of Inner Mongolia Medical College.The complicated root canals observed included calcified blocked root canals,instrument fracture root canals, MB_2 root canals,"C"type root canals and retreated root canals.Two groups were randomly departed according to the patients' will.180 complicated root canals were in the therapy group treated with surgical microscopes;in control group,179 complicated root canals were treated by traditional root therapy methods without surgical microscopes. From two aspects of statisties and clinic,two groups' achievement ratios were compared.Results Statistically achievement ratios of five kinds of root canals in the therapy group were 68.18 %,71.43 %,70.00 %,83.33 %, 80.39 % respectively,higher than those in the control group which were 13.33 %,16.67 %,25.00 %,22.73 % and 38.46 % respectively.The differences had obvious statistical significance(x~2=21.607,23.572,8.120,19.100, 20.488;P=0.000,0.000,0.004,0.000,0.000,P

Objective To investigate association between polymorphisms of the tumor necrosis factor α-induced protein 3 (TNFAIP3)interacting protein 1 (TNIP1)gene and systemic lupus erythematosus (SLE)in a Chinese Han population. Methods Blood samples were collected from 284 patients with SLE of Han nationality(SLE group)and 630 healthy controls of Han nationality (control group). Ligase detection reaction (LDR)was performed to determine the genotypes of 120 single nucleotide polymorphisms (SNPs)in the TNIP1 gene. Data were analyzed with the PLINK 1.07 package and Haploview software. Results After quality control, data on 105 SNPs underwent statistical analysis finally. Four SNPs including rs3805433, rs12516176, rs6869605 and rs4958882 in the TNIP1 gene were significantly associated with SLE (OR: 1.50 - 1.53, all P < 4.72 × 104), and there was a significant increase in the frequency of rs3805433 C, rs12516176 C, rs6869605 C and rs4958882 G alleles in the SLE group (0.301 - 0.306)compared with the control group (0.221 - 0.225). There was strong linkage disequilibrium between these 4 SNPs (r2 ≥ 0.871, D′ ≥ 0.938). In addition, moderate linkage disequilibrium was observed between these 4 SNPs and a previously reported SLE-related SNP rs10036748 (r2 ≥ 0.073, D′ ≥ 0.868). The frequency of the haplotype H2: CCCGT was significantly higher in the SLE group than in the control group(0.290 vs. 0.210, OR = 1.54, P < 4.72 × 10-4). Conclusion TNIP1 gene polymorphisms are associated with SLE in Chinese Han population.

ObjectiveTo investigate the influence of pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) on lipid variations of first and third trimester.MethodsA retrospective analysis was conducted on 2 593 singleton pregnant women without diabetes from 15 hospitals in Beijing from June 20 to November 30 in 2013. Serum lipid levels were determined in all of these women at the first trimester (<14 weeks) and the third trimester (≥28 weeks). Demographic data and medical information were collected individually through questionnaires. The recruited gravidas were divided into normal pre-pregnant BMI group (BMI<25) and pre-pregnant overweight and obese group (BMI≥25) according to recommendations of the Institute of Medicine (IOM). Based on the same recommendations on normal GWG, the pregnant women in the two groups were further assigned to two subgroups including normal GWG and over GWG group. The serum lipid levels in both first and third trimester and the increases from first to third trimester were compared between the normal and abnormal BMI groups with two independent samplet-test.Results(1) The levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) in the third trimester were all significantly higher than those in the first trimester in the normal BMI group [(6.47±1.17) vs (4.63±0.80), (3.14±1.19) vs (1.22±0.70), (1.94±0.44) vs (1.85±0.49) and (3.56±1.00) vs (2.29±0.67) mmol/L,t=-61.250,-65.909,-6.448 and-49.952, allP<0.01]. And the same results were shown in the abnormal BMI group [(6.20±1.14) vs (4.75±0.88), (3.31±1.20) vs (1.44±0.70), (1.86±0.44) vs (1.65±0.37) and (3.30±0.89) vs (2.51±0.82) mmol/L, t=-18.756,-25.165,-6.905 and-12.191,allP<0.01]. Significant differences were identified between the normal and abnormal pre-pregnant BMI groups both in first and third trimester (allP<0.05). (2) The increases of TC from early to late pregnancy in the abnormal BMI group was lower than that in the normal BMI group [(1.45±1.01) vs (1.84±1.02) mmol/L,t=6.664,P<0.01], but the increase of HDL-C was higher [(0.21±0.39) vs (0.09±0.51) mmol/L,t=-4.301,P<0.01]. (3) In the normal BMI group, the increase of TC and HDL-C between the third and the first trimester was lower in the over GWG subgroups than in the normal GWG subgroups [(1.77±0.96) vs (1.89±1.05) mmo/L,t=-2.802,P=0.005; (0.06±0.41) vs (0.12±0.58) mmo/L,t=-2.588,P=0.010], but the increase of TG was higher [(2.00±1.07) vs (1.86± 1.18) mmo/L,t=3.015,P=0.003]. While in the abnormal BMI group, smaller increase of HDL-C was found in the over GWG subgroup than in the normal GWG subgroup [(0.17±0.35) vs (0.29±0.44) mmo/L,t=-2.664, P=0.008].ConclusionsThe lipid levels during pregnancy are significantly higher in late pregnancy than in early pregnancy. Pre-pregnancy BMI has much more effect on lipid variations during pregnancy than GWG, which primarily affect the lipid levels of women with normal pre-pregnancy BMI.

Objective To investigate the incidence of gestational diabetes mellitus (GDM) and perinatal outcome in Beijing in 2013. Methods Fifteen hospitals in Beijing were selected by systematic and cluster sampling method. Clinical data of 15 194 pregnant women who attended prenatal care and delivered in these hospitals between June 20 and November 30, 2013 were collected. And 2 987 pregnant women were diagnosed with GDM (GDM group), and 11 999 had no diabetes (non-GDM group). The incidence of GDM, perinatal outcome and complications in mother and infant were compared between the two groups. Two independent samples t-test and Chi-square test were used for statistical analysis. Results The incidence of GDM in Beijing was 19.7%(2 987/15 194). The average age was much higher in GDM group than in non-GDM group [(29.4±4.5) vs (28.0±4.2) years, t=285.705, P<0.05]. The pre-pregnancy weight was much higher in GDM group than in non-GDM group [(59.5±10.2) vs (56.1±8.6) kg, t=352.565, P<0.05]. The incidence of GDM in pre-pregnancy overweight and obese women [29.9%(664/2 230) and 38.8%(250/664)] was much higher than in normal pre-pregnancy weight and low pre-pregnancy weight women [18.0%(1 777/9 890) and 12.9%(273/2 118)] (χ2=296.843, P<0.05). The incidence of GDM in pluripara was higher than in primipara [21.2% (910/4 298) vs 19.4%(2 077/10 688),χ2=5.813, P<0.05]. The incidence of GDM in gradeⅢhospitals was higher than in grade Ⅱ hospitals [21.1% (1 654/7 849) vs 18.7% (1 333/7 173), χ2=13.440, P<0.05]; and the incidence in urban areas was higher than in rural areas [21.3%(2 028/9 521) vs 17.1%(896/5 249),χ2=39.137, P<0.05]. The rate of cesarean section was 47.1%(1 407/2 987) in GDM group, significantly higher than in non-GDM group [39.8% (4 782/11 999)] (χ2=72.204, P<0.05). The incidences of preterm labor [7.3%(217/2 987)], hypertensive disorders [6.3%(185/2 987)], large-for-gestational-age infants [9.2%(275/2 987)], macrosomia [9.5%(283/2 987)] and neonatal ward admission [8.6%(258/2 987)] were all significantly higher in GDM group than in non-GDM group [5.7%(686/11 999), 3.9%(454/11 999), 5.8%(694/11 999), 7.2%(861/11 999), and 6.5%(778/11 999), respectively] (χ2=10.117, 34.371, 79.378, 20.346 and 17.236, respectively, all P<0.05). Conclusions The incidence of GDM is still high in Beijing, and advanced maternal age and pre-pregnancy overweight or obesity are high risk factors for GDM. The rate of preterm labor, hypertensive disorders, and macrosomia in GDM group is higher than in normal fasting glucose group. Systematic obstetric care for GDM should be intensified in Beijing.

Objective To investigate the association between endoplasmic reticulum aminopeptidase 1 (ERAP1)gene polymorphisms and psoriasis vulgaris (PsV)in a Chinese Han population. Methods Five milliliters of venous blood samples were collected from 289 patients with PsV and 292 human controls of Han nationality after informed consent. Three single nucleotide polymorphisms (SNPs)in the encoding area of the ERAP1 gene, including rs27044, rs30187 and rs26653, were genotyped by ligase detection reaction (LDR). With the PLINK 1.07 package, statistical analysis was carried out by using the chi-square test for comparisons of allele and genotype frequencies between the patient group and control group. The allelic odds ratio (OR)and its 95% confidence interval (CI)were calculated. In addition, haplotype analysis was conducted with the Haploview software. Results The frequencies of rs30187-C and rs26653-G alleles were significantly lower in the patient group (0.460 2 and 0.430 8 respectively), especially in patients with early-onset PsV(0.448 5 and 0.422 7 respectively), than in the control group(0.534 2 and 0.501 7 respectively, all P <0.05). The SNPs rs27044, rs30187 and rs26653 showed strong linkage disequilibrium with each other (r2 ≥ 0.717, D′ ≥0.962). Genotype analysis showed that the frequency of the rs30187 CC genotype was significantly lower in the patient group, especially in patients with early-onset PsV, than in the control group (P < 0.05 and 0.016 7 respectively)under a recessive mode of inheritance. Haplotype analysis revealed that the frequency of the haplotype H4: CTC was significantly increased in the patient group(0.050), especially in patients with early-onset PsV(0.052), compared with the control group (0.022, P < 0.05 and 0.016 7 respectively). Conclusions ERAP1 gene polymorphisms are associated with PsV, especially with early-onset PsV in Chinese Han population. The risk haplotype H4: CTC may be a susceptible factor for PsV.
