Objective To investigate the combined use of osteoarthritis treatment effect of lornoxicam and peptide drugs.Methods 260 patients with osteoarthritis treated in our hospital from May 2014 to June 2016 were selected, were randomly divided into study group and control group, each group of 130 cases.The patients in the control group were treated with sodium hyaluronate and lornoxicam, the study group was given bone peptide on the basis of the control group. The pain scores, knee function and adverse reactions were compared between the two groups.Results There was no significant difference in VAS and WOMAC scores between the two groups before treatment; after treatment, the improvement of VAS and WOMAC score in the study group was better than that in the control group (P<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups. Conclusion Sodium hyaluronate, bone peptide, lornoxicam and other drugs in the treatment of patients with osteoarthritis clinical efficacy is obvious, and fewer adverse reactions.

Objective To investigate the influencing factors of the controlled virtual touch tissue quantification (VTQ) in liver of patients with type 2 diabetes mellitus (T2DM) complicated withnon-alcoholic fatty liver disease (NAFLD). Methods Two hundred and twenty-seven patients with T2DM complicated with NAFLD were enrolled in this study,and the shear wave speed of the liver was measured by VTQ. Levels of the fasting plasma glucose, glycated hemoglobin,total cholesterol three acids glyceride, low density lipoprotein, high density lipoprotein , aspertate aminotransferase , alanine aminotransferase , gamma glutamyl transpeptidase and uric acid were measured. The relationships among VTQ and the severity of NAFLD , and those quantitative indexes were analyzed. Results Univariate analysis showed that the value of shear wave speed was negatively correlated with age,duration of diabetes,INS and HDL-C,while was positively correlated with HbA1c and AST. Conclusion Age, sex and levels of serum HbA1c,INS,AST and HLD-C might affect the values of shear wave speed in patients with T2DM complicated with NAFLD.

Objective To explore whether major depressive disorder（MDD）and the therapeutic effect of fluoxetine are related to a functional polymorphism-1019C/G in the promoter region of the 5-HT1A receptor（HTR1A）gene.Methods Genotype and allele frequencies of HTR1A receptor gene-1019C/G polymorphism in MDD patients and healthy subjects（control）were examined by PCR-RFLP technique.Before and after the MDD patients accepted fluoxetine treatment for 6 weeks,17-item Hamilton depression rating scales（HAMD）were made to determine the severity of the symptoms,the outcome and remission status.Results There were significant differences in-1019C/G gene genotypes and alleles distribution between the patients and the healthy control,G allele frequency of the MDD patient was higher than that of the healthy control（P 0.05）.There were significant differences in HAMD scores among the patients with different genotypes in MDD group（P 0.05）,the score of C/C genotype patient was especially higher than that of C/G genotype（P 0.05）and G/G genotype patient（P =0.008）.There was no statistical difference in the therapeutic effect of fluoxetine among the patients with different genotypes in MDD group（P =0.761）.Conclusion HTR1A gene-1019C/G genetic polymorphism might related to MDD,especially G allele might be the possible risk factor of MDD.C allele might be correlated with the degree of pathogenetic severity,especially patients with the-1019C/C carriers.-1019C/G genetic polymorphism was not related to the clinical outcome of MDD patients treated with fluoxetine.

Objective To explore the mutation and evolution of Yersiniapestis(Y. pestis) from the point of codon and 16S-ribosome. Methods Codon preference and 16S-ribosome of Y. pestis were analyzed by bioinformatics. Results Similar codon preference was found among 4 PCD1 Y. pestis, of the 3 old Y. pestis the codon preference between PMT1 and PCD1 was similar. There were some differences between PCD1, PCP1 and Yunnan 6 kb plasmid. Through the analysis of 16S-ribosome, the sequences were found similar in 11 strains of Y. pestis,Yersinia pseudotuberculosis was very close to Y. pestis, with only one nucleotide difference, mutated G-T, and corresponding amino acid methionine (M)-isoleucine (I). There were some differences in sequences of 16S-ribosome in Y. pestis, Escherichia coli and Pulex irritans. Conclusions The time for Y. pestis to obtain PCP1 is later than PMT1 does, in other words, the affinity of Y. pestis with PMT1 was closer than PCP1 with 6 kb plasmid;alteration of 16S-ribosomal nucleotide sites may cause changes in function and structure of 16S rRNA. The lower similarity between 16S-ribosomal sequences of Y. pestis and Pulex irritans indicates the time for co-evolution is very short,and the late emergence of Y. pestis.

OBJECTIVETo explore action mechanism of electroacupuncture (EA) at "Fenglong" (ST 40) for treatment of hyperlipidemia.

METHODSForty SPF-grade SD rats were randomly divided into a normal group (group A), a model group (group B), a model diet-control group (group C), a model + EA group (group D) and model diet-control + EA group (group E), 8 cases in each one. The rats in group A were fed with normal diet continuously while those in the rest 4 groups were fed with high-fat diet to establish hyperlipidemia model. Afterwards, the rats in group C and group E were fed with normal diet, while EA at "Fenglong" (ST 40) was applied in group D and group E, 30 min per time, once a day. After 28 days of treatment, macrophage was collected in each group. Oil red O-staining was applied to detect the formation of foam cells, and enzyme-linked immunosorbent assay (ELISE) was adopted to measure the contents of total cholesterol (TC) in macrophage and analyze the rate of cholesterol efflux.

RESULTSThe counts of positive cells of oil red O-staining and the contents of TC in the group B, group C and group D were significantly increased compared with those in the group A (all P < 0.01). The counts of positive cells and contents of TC in the group C, group D and group E were significantly clecreased compared with those in the group B (all P < 0.01), and the decline in group D was more obvious than that in the group C (all P < 0.01). Compared with group C and group D, the counts of positive cells and contents of TC in the group E was obviously decreased (all P < 0.01), which was not statistically different from group A (P > 0.05). In the meantime, compared with group C, the rate of cholesterol efflux in group D and group E was significantly increased (both P < 0.01), and the rise in group E was more obvious than that in the group D.

CONCLUSIONThe electroacupuncture at "Fenglong" (ST 40) could significantly prohibit the transformation of macrophage into foam cell and increase rate of cholesterol efflux in macrophage, which could prevent and reverse the formation of foam cell and play an essential role in treating hyperlipidemia and stopping it from developing into a further level.

Objective To explore the relationship between childhood abuse experience,parent and peer attachment and depression in adolescents.Methods A total of 736 junior students from the 7th,8th and 9th grades of 2 public schools in Xinxiang City and Jiyuan City Henan province completed the questionnaires.Childhood Trauma Questionnaire(CTQ),Inventory of Parent and Peer Attachment(IPPA) and Depression Self-Rating Scale for Children(DSRSC) were employed the childhood abuse experience,parent attachment quality and depressive mood in adolescents,respectively.The hierarchical regression analysis was used to examine the relationship between parent and peer attachment,child abused experience and depression.Results Male participants reported high score of childhood abused than female participants(33.29±7.89 and 31.05±6.01,t=4.343,P=0.000).There were no significantly gender difference in mother attachment(male:59.89±15.86,female:61.45±16.48,t=-1.303,P=0.193),father attachment(male:59.32±17.17,female:60.28±16.95,t=-0.764,P=0.445) and depression(male:7.68±5.27,female:7.31±4.21,t=1.057,P=0.291).Childhood abuse had a positive correlation with adolescent depression(r=0.408,P=0.000),which negatively correlated with mother and father attachment(r=-0.544,-0.417,respectively,Pa=0.000).There was a positive correlation between mother attachment and father attachment(r=0.604,P=0.000),and both of them had negative correlation with depressive disorder(both r=-0.426,Pa=0.000).Mother and father attachment were the partial mediation of the relationship between childhood abuse and adolescent depression.Conclusions Male adolescents suffered more maltreatment than female adolescents.There are no gender difference in parent attachment and depression.Parent attachment plays the partial mediator role in childhood abuse and adolescent depression.Results reveal the importance of assessment and consideration of parent attachment in the intervention of depression in abused adolescents.

Objective To observe dynamically osteopontin(OPN) expression in the renal tubules of streptozotocin(STZ) induced diabetic rats, and to explore the relationship between OPN and angiotensinⅡ(AngⅡ), nuclear transcription factor-?B(NF-?B), and renal injuries. Methods Male SD rats were injected with STZ to induce diabetes mellitus, which were randomly divided into 5 groups and meanwhile there were other 5 age-matched normal control groups. Immunohistochemistry was employed to observe the expression of OPN, AngⅡ, NF-?B and fibronectin(FN) in renal tubules. The OPN and I-?B protein in renal cortex was detected by Western blot methods. Blood glucose, serum creatinine and 24 h urine protein were examined. The renal morphology was checked through light microscopy.Results The AngⅡand NF-?B expression from DM day 3, OPN expression from day7, FN from week 2 in renal cortex or tubules was increased as compared with control groups, while I-?B protein in renal cortex was gradually decreased since day 3. In DM week 4, there were positive correlations between OPN and AngⅡ, NF-?B, FN and 24 h urine protein. Conclusion An increase of OPN expression in the renal tubules of diabetic rats may be regulated by AngⅡ and NF-?B, and therefore participates the injury mechanisms of renal tubulo-intestitium.

Objective To investigate the effect of non-alcoholic fatty liver disease (NAFLD) on virologic response in chronic hepatitis B patients treated with nucleos(t)ide analogues.Methods Three hundred and thirty-two treatment-naive patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) who visited clinic or hospitalized in the First Affiliated Hospital of Wenzhou Medical College from January 2007 to December 2009 were enrolled and finally 316 patients completed the research.Among them,106 patients were diagnosed with CHB complicated with NAFLD by ultrasonography (NAFLD group),and the remaining 210 patients were diagnosed with simple CHB (CHB group).Patients in both groups were treated with combination therapy of lamivudine (LAM) plus adefovir dipivoxil (ADV) or entecavir (ETV) monotherapy for 96 weeks.Alanine aminotransferase (ALT) levels,virologic response and serological response were compared pre-and post-treatment in both groups.Enumeration data was compared using x2 test,and correlation analysis was performed using Logistic multivariate regression analysis.Results Rates of hepatitis B virus (HBV) DNA clearance in the NAFLD group at week 12,24 and 48 were 46.2％,61.3％ and 74.5％,respectively,which were all significantly lower than those in CHB group (61.9％,73.8％ and 83.8％,x2 =7.051,5.195,3.895,respectively; all P＜0.05).However,rates of HBV DNA clearance were 85.8％ in the NAFLD group and 91.9％ in the CHB group at week 96.This difference did not reach the level of significance (x2 =2.838,P＞0.05).Rates of HBeAg loss in the NAFLD group were 27.4％ at week 48 and 37.7％ at week 96,compared to 33.3％ and 44.8％ in the CHB group.There was no significant difference in these two groups (x2 =1.169,1.424,both P＞0.05).Rate of HBeAg seroconversion in the NAFLD group was significantly lower than that in the CHB group at week 96 (17.9％ vs29.5％,x2=4.972,P＜0.05).Rates of ALT normalization were also found to be significantly lower in the NAFLD group than those in the CHB group at week 48 (69.8％ vs 80.5％,P＜0.05) and at week 96 (82.1％ vs 91.0％,P＜0.05).Multivariate regression analysis demonstrated that serum levels of triacylglycerol (OR=3.725,P=0.000),uric acid (OR=1.005,P=0.040) and fasting blood-glucose (OR=3.067,P=0.000) were independent risk factors associated with NAFLD.NAFLD was found to be a risk factor of virologic response at each time point throughout the treatment.(week 12,OR=2.749,P=0.001; week 24,OR=1.981,P=0.030; week48,OR=2.348,P=0.021; week 96,OR=8.053,P=0.001).Conclusions During antiviral therapy,NAFLD may affect biochemical and serological responses in CHB patients treated with nucleos(t) ide analogues,and may affect early virologic response in these patients.
