Objective To study the differences of anal manometry among dirrhea-dominant(DD), constipation-dominant(CD) irritable bowel syndrome(IBS) and functional constipation(FC), and to evaluate effects of sex and age on these parameters.Methods Age-matched 18 DD-IBS, 14 CD-IBS and 30 FC patients were selected, and 18 volunteers as healthy controls. Anal manometry was evaluated with localized point pull-extraction technique.Results The pressure parameters in DD-IBS, CD-IBS and FC were no significantly difference from those in healthy controls, but the threshold volume of gas to induce RAIR was significantly larger(P

Objective To probe the clinical values of the human serum glycoprotein profiles for the diagnosis of common gynecological tumors. Methods A total of 123 clinical serum samples which included 31 breast cancer, 24 cervical cancer, 19 ovarian cancer and 49 healthy individuals were collected. A lectin microarray consisting of 15 lectins with different glycan binding specificities was used to determine the glycoprotein profiles of serum sam-ples. Stepwise discrimination analysis method was adopted to establish function model of clinical serum samples classification with SPSS 15. 0 software. Results Two grades of diagnostic discrimination function models were es-tablished. The first grade discrimination function could differentiate gynecological tumors from healthy individuals, the diagnostic accuracy rates of retrospective inspection were 85. 7% and 83. 8% respectively, and the total diag-nostic accuracy rate was 84.6%. The second grade discrimination function was used to differentiate breast tumor, cervical tumor and ovarian tumor, the diagnostic accuracy rates of retrospective inspection were 96.8%,75.0%and 78.9% respectively, and the total diagnostic accuracy rate was 85.1%. Conclusion The human serum gly-coprotein profiles are associated with gynecological tumors, and the established discrimination function models based on lectin microarray data have a helpful reference value for the clinical diagnosis of gynecological tumors.

EPA exists wildly in artery vascular endothelium and could be activated by endogenously activated substances and regulate the vascular tone. The endothelium-dependent vascular relaxation mediated by EPA has been used for almost 20 years as an indicator of endothelium dysfunction. In many cardio-vascular diseases, EPA function was down-regulated. The pharmacological profiles of EPA could be characterized by muscarinic properties, as well as non-muscarinic properties in selectivity for agonists and antagonists and in binding characteristics. The endogenous ligand, receptor type and molecular pharmacological characteristics of EPA are waiting to be investigated.

Objective To determine the influence of total glucosides of paeony (TGP) on bone density, protein level of skeletal muscle and relative cytokine of osteoporotic rats. Methods Six-month-old SD rats were shamed as control (8 rats) or were ovariectomized (24 rats). The ovariectomized (16 rats) +TGP low dose and high dose group were treated with 50 mg/(kg?d) TGP and 150 mg/(kg?d) TGP respectively for 12 weeks. After the animals were sacrificed, IL-6, TNF-?, IGF-1, TGF-? in serum, protein level of skeletal muscle in right quadriceps femoris, and bone density of right femur and lumbar vertebra were determined. Results Compared with the ovariectomized group, the bone density and the protein level of skeletal muscle in TGP group increased significantly from the baseline (P

OBJECTIVE:To systematically evaluate the efficacy and safety of cetuximab in the adjuvant chemotherapy treat-ment of advanced non-small cell lung cancer(NSCLC),and to provide evidence-based reference for clinical treatment. METH-ODS:Retrieved from Cochrane Library,PubMed,CJFD and Wanfang database,randomized controlled trials (RCT) about cetux-imab adjuvant chemotherapy (test group) versus single chemotherapy (control group) in the treatment of advanced NSCLC were collected,and Meta-analysis was performed by using Rev Man 5.2 statistical software after extracting data and evaluating quality. RESULTS:A total of 8 RCT were included,involving 2 367 patients. Results of Meta-analysis showed survival rate in 1 year [OR=1.33,95%CI(1.08,1.64),P=0.006],partial remission rate [OR=1.48,95%CI(1.23,1.78),P<0.001],total effective rate [OR=1.34,95%CI(1.19,1.51),P<0.001],incidence of leucopenia [OR=1.50,95%CI(1.23,1.83),P<0.001],incidence of rash [OR=53.26,95%CI(13.09,216.65),P<0.001] and incidence of infusion reactions [OR=3.72,95%CI(1.86,7.42),P<0.001] in test group were significantly higher than those of control group,there were significant differences in 2 groups. However,there were no significant differences in the complete remission rate [OR=1.57,95%CI(0.91,2.70),P=0.11] and incidences of other ADR(P>0.05). CONCLUSIONS:Cetuximab has good efficacy in the adjuvant chemotherapy treatment of advanced NSCLC,however,the incidence of ADR should be prevented in clinic. Duo to the methodology limit of included studies,large-scale and high quality RCT are required for further validation of the conclusions.

Background:Chronic atrophic gastritis(CAG)is a kind of chronic gastritis with atrophic changes of gastric mucosa. The studies on peripheral blood biomarkers in CAG are rare. Aims:To investigate the methylation of peripheral blood CpG sites in Runx3 gene promoter region in CAG patients. Methods:Eighty-two mild CAG patients,73 moderate to severe CAG patients from June 2013 to May 2014 at Daqing Oilfield General Hospital were enrolled,and 45 patients with normal gastric mucosa were served as controls. The methylation of CpG sites in Runx3 gene promoter region was measured by MALDI-TOF-MS. mRNA expression of Runx3 was determined by fluorescent quantitative PCR,and the protein expression of Runx3 was determined by Western blotting. Results:Compared with the control group and mild CAG group,methylation levels of CpG13,CpG14 and CpG15 sites in Runx3 gene promoter region were significantly increased in moderate to severe CAG group(P < 0. 05),the mRNA and protein expressions of Runx3 were significantly decreased( P < 0. 05). No significant differences in methylation of CpG sites in Runx3 gene promoter region and mRNA and protein expressions of Runx3 were found between mild CAG group and control group( P >0. 05 ). Conclusions:The hypermethylation of peripheral blood CpG13,CpG14 and CpG15 sites in Runx3 gene promoter region can inhibit the expression of Runx3 in CAG patients,and can be used potentially as the biomarker for clinical staging of CAG.

Objective To evaluate the effect of maternal separation stress on the behavior of neonatal rd mice.Methods Neonatal rd mice were divided into maternal separation (MS) group (n=9) and control group (n=9).MS-stress was induced in the MS group by 4-hour-separation per day for 28 days.Open field test,elevated plus maze test,forced swim test and tail suspension test were used to evaluate the anxiety-like and depression-like behavior of the neonatal rd mice.Results The stay time and distance travelled of MS group in the central zone were 0.88％ and 28.17±5.65 cm,respectively,significantly shorter than that of the control group (2.61％,109.9±9.79 cm.P =0.04,P =0.001).Compared with the control group,the stay time in open arms of the MS group was significantly decreased (P<0.01),while the immobility time in forced swim test and tail suspension test of the MS group were 126.5±10.22 s and 21.56±6.83 s,significantly longer than that of the control group (77.75±16.83 s,P =0.02,7.37±3.22 s,P =0.03).Conclutions The 28-day maternal separation stress can significantly increase the anxiety-like and depression-like behavior in neonatal rd mice.

Objective To investigate the association between Cardiomyopathy associated 5 (CMYA5) polymor?phisms and schizophrenia in the Uygur Chinese population. Methods Taq-man assay was used to detect CMYA5 gene rs3828611 in 684 schizophrenia patients and 678 healthy controls from Chinese population. The positive and negative symptoms scale (PANSS) was used to evaluate patients’symptoms. Results Neither the genotype nor the allele frequen?cies of rs3828611 was significantly different between the patients and the controls (P>0.05). The differences were not sig?nificant in either each gender subgroup or in each age (teenager and adult) subgroup (P>0.05). The total score and the sub scores of PANSS were not significantly different among patients with different genotype groups (P>0.05). Conclu?sions There is no association between CMYA5 rs3828611and schizophrenia in the Uygur Chinese population.

Objective To explore the effect and safety of rituximab (RTX) in children with frequently relapsed nephrotic syndrome.Methods Twelve children (8 male and 4 female) with frequently relapse nephrotic syndrome were treated with RTX.They all showed resistance to various immunosuppressive agents and relapsed when steroid was reduced at 1.5-2.0 mg/kg.All immunosuppressive agents were stopped.Steroid was prescribed at doses of 2 mg/(kg · d),followed by alternate-day dosing (2 mg/kg) after proteinuria was negative for 5 days,and then tapered by 5 mg every 2 weeks until to low dose (＜ 0.5 mg/kg on alternate day) or discontinued.RTX was administered at a dose of 375 mg/m2 once every week for 3 weeks.Results The patients were followed up for 4-19 months [median (7.79 ± 3.00) months].Proteinuria turned negative on 1-14 d after first RTX treatment.Mean steroid dosages were significantly reduced than before treatment [alternate-day dosing (1.83 ± 1.02) mg/kg vs alternate-day dosing (0.34 ± 0.16) mg/kg,t =3.78,P =0.002].Gingival hyperplasia and Cushing appearance were significantly improved and steroid-induced glaucoma disappeared.The height was significantly increased compared with before treatment [(2.21 ± 1.40) cm/year vs (8.27 ±2.10) cm/year].Six cases had no relapse during follow-up.Another 6 cases relapsed in 5.5-19.0 months.All patients showed CD19 + B lymphocytes depletion after RTX treatment.However,CD19 + recovery could be seen in 5.5-12.0 months.Serum immunoglobulin did not significantly change.None of the patients was found with adverse events.Conclusions RTX can significantly reduce the dosage of steroid or even stop medication in children free of immunosuppressive agents,maintain remission for (7.79 ± 3.00) months,significantly improve the adverse reaction induced by steroid and immune-suppression.Thus,for children with frequently relapsed nephritic syndrome/steroid-dependent nephrotic syndrome who show resistance to immunosuppressive therapies,RTX treatment may be considered.
