Objective To explore the role of plasmids in inducing drug-resistance in Neisseria gonor-rhoeae.Methods The change of drug-susceptibility in Neisseria gonorrhoeae was compared before and after experiments of resistant plasmids conjugation,transformation and deleting.Results The drug-resistance was transferred from resistant strains to sensitive strains through the conjugation and transformation of resistant plasmids,while the drug susceptibility could be recovered through deleting such plasmids from resistant strains.Conclusion The plasmids play an important role in the development of drug-resistance in Neisseria gonorrhoeae.

Objective To investigate the histological injury as well as the risk factors for the course of HBeAg-negative chronic hep-atitis B virus( HBV)-infected patients with persistently normal alanine aminotransferase ( ALT) levels ( PNAL) . Methods Ninty four patients of HBeAg-negative chronic HBV-infected with PNAL were performed liver puncturing. The ALT, HBV markers, and liver histo-logical changes were detected. The gender, age, family history, HBV-DNA and HBsAg levels were compared between different patients with liver inflammation and fibrosis. And the Logistic model was used during the analysis of independent risk factor. Results Among 94 cases, patients with inflammatory necrosis classification≥G2 accounted for 74. 5%, fibrosis grading≥S2 accounted for 27. 7%. Patients in the group of inflammatory necrosis classification≥G2 was older than the group of < G2, and the ALT level of≥G2 group was higher, as well as a higher HBV-DNA. What is more,Patients in the group of inflammatory necrosis classification ≥G2 were mainly male, and were associated with a family history of hepatitis B. Patients in the group of fibrosis stage ≥S2 was older than < S2 group, and the ALT level of fibrosis stage ≥S2 group was higher. And those patients were often associated with a family history of hepatitis B, but there was no significant difference among the HBV-DNA level and gender constitution. HBV-DNA and family history were the independent risk fac-tors of liver inflammation necrosis≥G2, and family history was the only independent risk factor of fibrosis stage≥S2. Conclusion The patients of HBeAg-negative chronic HBV-infected with PNAL, regardless of the ALT and HBV-DNA, must have a liver biopsy. The pa-tients with high level of HBV-DNA and with a family history of hepatitis B should be performed liver puncturing accordingly.

Objective To investigate the expression of nerve growth factor receptors, P75 neurotrophin receptor (P75~(NTR)) and tyrosine kinase A (TrkA), and to explore their role in the pathogenesis of psoriasis vulgaris. Methods In situ hydridization and immunohistochemical technique were used respectively to detect the expression of P75~(NTH) and TrkA mRNA and proteins in lesional and non-lesional skins of 38 patients with psoriasis vulgaris (21 cases in progressive stage, 17 cases in static stage), and in normal skins of 10 healthy controls. Results In the case of expression of P75~(NTR) and TrkA mRNA and proteins, patients had significantly higher level than the normal control (P

Objective To investigate the sleep quality of maintenance hemodialysis (MHD) patients and analyze its associated factors. Methods The convenience sample method was used to choose 424 MHD patients from 7 hospitals.A set of questionnaires were used in this investigation,including demographic data form,Pittsburgh sleep quality index (PSQI),restless legs syndrome (RLS),social support rate scale (SSRS),subjective global assessment (SGA),family APGAR index (APGAR) and family burden scale of disease (FBS). Results PSQI score of 395 MHD patients (93.2％) was ≥5.APGAR and social support total points were negatively correlated with sleep quality (r=-0.133,P=0.006; r=-0.105,P=0.031).Family burden total point was positively correlated with sleep quality (r=0.215,P=0.000).Nutrition (F=46.123,P=0.000),restless legs syndrome (F=9.392,P=0.000) and sleep apnea syndrome (F=5.645,P=0.001) were closely associated with sleep index scores. Conclusions Incidence of poor sleep quality in MHD patients of our study is quite high.Sleep quality of MHD patients is correlated with lots of factors,such as family concern,social support.

Objective To investigate the effects of individual and collective health education on hemodialysis patients with hyperkalemia. Methods Thirty hyperkalemia patients treated with maintenance hemodialysis from Mar. 2013 to Mar. 2014 were set as the control group, in which the patients were given pre-established individual health education by the hemodialysis nurse weekly. Another 30 patients of the same sort, as the experiment group, were treated with individual health education combined with collective health education weekly from Apr. 2014 to Apr. 2015. The two groups were compared in term of serum potassium before and after intervention. Result Serum potassium of the experiment group after the intervention were significantly lower than the control group and the experiment group after the intervention (P<0.001). Conclusion Individual health education combined with collective health education can change traditional indoctrination one-way communication to the two-way communication conversion , make the patients consciously change their incorrect dietary behaviors, and reduce the serum potassium levels in the hemodialysis patients with hyperkalemia.

Objective To analyze the clinical features of Weber-Christian disease (WCD) and to make a review of the literature for early diagnosis and treatment.Methods The clinical features of an atypical WCD patient who had been misdiagnosed as polymyositis were analyzed.Results WCD was characterized by subcutaneous nodules and systemic symptoms.Repeating physical examination and biopsy in time were important if the nodules were not obvious.Conclusion WCD is often misdiagnosed because of the complicated clinical manifestations.Carefully physical examination and timely biopsy are help for early diagnosis.

This study was aimed to explore the clinical efficiency of modified Xiao-Y ao (XY) powder and acupuncture in the treatment of diarrhea-predominant irritable bowel syndrome (D-IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric-coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89%(P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.

Objective To explore the expression of matrix metalloproteinase-11 (MMP-11) gene in gastric cancer and its correlation with transcription factor Sp1.Methods The expressions of the MMP-11 and Sp1 in level of RNA and protein in 11 specimens from the gastric cancer patients s were detected by RT-PCR,differential PCR and Western-blot,respectively.Results Electrophoresis illustration showed MMP-11 mRNA expression had significant differences in eight pairs of gastric cancer tissues and normal tissues,including 7 pairs of over expressed in gastric cancer tissues and low or no expression in normal tissues,and 1 pair of low expression in cancer tissues but high in normal tissues.The relative molecular weight of Sp1 protein was mainly 95×103 in cancer tissue and 106×103 in normal tissues.Activated MMP-11 protein mainly was over expressed in gastric cancer tissues,and low or no expression in normal tissues,but degradable MMP-1 1 protein was not observed.The enzyme prototype of and activated type of MMP-11 protein were also associated with Sp1 protein.Conclusions The MMP-11 mRNA expression in gastric tissue is higher than that in the adjacent tissues.Sp1 protein and MMP-11 protein are expressed in gastric cancer,but are low or no expression in normal tissue.There is relationship between Spl and MMP-11.

Objective To verify the presence of anti-ovary antibodies in systemic lupus erythematosus (SLE) and its possible correlations with serum levels of hormone profile and menstrual disturbances in patients with SLE.Methods Clinical data of 78 consecutive paticnts who fulfilled 4 or more of the ACR 1997 revised criteria for SLE were studied and compared with 40 age-matched healthy controls,including anti-ovary antibodies.Results 27 (34.6％ ) patients with SLE,and 1 (2.5％) of the healthy controls tested positive of anti-ovary antibodies.The levels of E2 and T and P decreased[ E2:( 80.96 ± 36.2 ) ng/L vs ( 118.53 ± 42.4 ) ng/L; T:( 3.85 ± 1.18 ) nmol/L vs ( 6.43 ± 2.28 ) nmol/L; P:( 1.37 ± 0.59 ) μg/L vs ( 3.92 ± 1.23 ) μg/L],and the levels of FSH and LH and PRL increased in SLE patients when compared with healthy controls [ FSH:( 19.17 ± 9.26)IU/L vs (10.18 ±7.27 )IU/L; LH:( 21.19 ± 12.44)IU/L vs (13.79 ±8.27)IU/L;PRL:(6.18 ± 2.27 ) μg/L vs (2.37 ±0.63)μg/L,P ＜0.05 orP ＜0.01].The higher SLEDAI score,higher rate of menstrual disturbances (6.3 ±2.8 vs 3.5 ± 1.7,81％ vs 47％,P ＜0.05 or P ＜ 0.01 ) and decreased serum level of E2 [ (64.13 ± 26.36 ) ng/L vs ( 82.83 ± 28.71 ) ng/L,P ＜ 0.05 ]were found in SLE patients with anti-ovary antibodies positive than in SLE patients with anti-ovary antibodies negative.Conclusions The presence of anti-ovary antibodies was 34.6％ in SLE,and may correlate to decreased serum level of E2 and menstrual disturbance.

AIM: To find new gene function associate with active lupus nephritis (LN) through study on the difference in gene expression of peripheral blood mononuclear cells between LN patients and healthy controls by gene chip. METHODS: The CSC-GE-80 chip containing 8 000 spots of cDNAs were used to investigate the difference of the expression. Both the total RNA from peripheral blood mononuclear cells of active LN patients and healthy donors were reversely transcribed to cDNA with the incorporation of fluorescent( cy3 and cy5) labeled dCTP to prepare the hybridization probes. After hybridization, the gene chip was scanned for the fluorescent intensity. The differentially expressed genes were screened. We repeated that in three groups of LN patients and healthy controls, respectively, and only the genes that have differential expression in all three chips were considered associated with LN. RESULTS: 75 genes were identified to be differently expressed in all three groups of LN patients as compared with healthy controls, including 42 up-regulated genes and 33 down-regulated ones. CONCLUSION: The present study represents a global view of gene expression of LN and provides important clues for further study of LN related genes. And it also suggests defensin ? 1, S100A8, S100A9 may be involved in the pathogenesis of LN.
