Objective To study pre-thrombosis state in patients with cor pulmonale and analyze the value of treatment with low molecular heparin (LMH). Method 46 patients with cor pulmonale were divided into LMH group and routine one. Von Willebrand factor (vWF), prethrombin F 1+2 fragment (F 1+2 ), Fibrinogen (Fg), granule membrane protein (GMP-140) and D-dimer fragment (DD) were detected separately.Result The concentrations of WF,F 1+2 ,Fg,GMP-140 and DD in the patients with cor pulmonale were significantly higher than control. In LMH group, these variables and PaCO 2 decreased and PaO 2 increased markedly after treatment. In routine group, these blood-gas index slightly improved, but no decrease were observed in coagulation variables. Conclusion Early detection and diagnosis of pre-thrombosis state in patients with cor polmanate and timely treatment with LMH can be beneficial to these patients during acute state.

Objective To elucidate the molecular basis for induced resistance of N. gonorrhoeae to ceftriaxone in vitro. Methods The reference strain ATCC49226 and clinical isolate ZSSY00205 of N. gon-orrhoeae were exposed to subinhibitory concentration of ceftriaxone for the induction of resistance. Then,suppression subtractive hybridization was performed with the pre-induction parent strains as drivers and post-induction mutant strains as testers to create a subtractive cDNA library. Following that, a total of 192 clones were randomly selected from the library, and arrayed by spotting onto nylon membranes. Finally, dif-ferentially expressed genes were screened by hybridization with labeled-RsaI restriction fragments from the sensitive and resistant N.gonorrhoeae strains respectively, and analyzed by sequencing and homology research using Blast program. Results A subtractive library for these resistant N.gonorrhoeae strains was generated by SSH technique. Microarray analysis and homology research confirmed 5 genes related to ceftriaxone resistance, i.e. mtrR, mtrC, gyrB, rpsJ and PJD1. Conclusions The induced resistance of N. gonorrhoeae to ceftriaxone may be associated with mtrR, mtrC, gyrB, rpsJ and PJD1 genes which probably mediate the resistance by enhancing the activity of efflux pump system.

Objective To study the effect of family intervention on treatment compliance and social function for patients with schizophrenia.Methods 76 patients with schizophrenia were randomly divided into the intervention group and the control group with 38 cases in each group.The patients in both groups were treated with antipsychotics,the control group was only given general hygiene education,while the intervention group was given targeted systematic family intervention for 1 year.The Nurse-Brief Psychiatric Rating Scale (N-BPRS),Social Disability Screening scale (SDSS),Insight and Treatment Attitudes Questionnaire (ITAQ),medication adherence questionnaire were used before and after the intervention and then the recurrence rate within 1 year was calculated.Results At the end of 1 year the total scores of NBPRS,SDSS,medication adherence questionnaire significantly decreased in the intervention group and were signif-icantly lower than those of the control group at the same period,while the total score of ITAQ significantly increased in the intervention group and was significantly higher than those of the control group at the same period.The recurrence rate of the intervention group was significantly lower than the control group.Conclusions The family interventions contribute to promote insight recovery of the patients with schizophrenia ef-fectively and improve their treatment compliance,reduce recurrence and to promote the recovery of its so-cial function.

Objective To investigate the incidence, clinical patterns, and species distribution of pathogenic fungi of onychomyeosis in patients with chronic viral hepatitis (CVH), and to analyze the relationship between onychomycosis and CVH. Methods From November 2005 to October 2006, direct microscopy and fungal culture were performed on nail samples from CVH patients with clinically suspected onychomycosis in the two largest institutions for communicable disease control in Guangzhou city. The incidence, clinical patterns, and species distribution of pathogenic fungi of onychomycosis were assessed based on the findings in mycologic examinations. Results The study randomly recruited 995 patients with CVH, and onychomycosis was diagnosed in 116 patients. The incidence of onychomycosis was 11.66% in total, 6.20%, 8.59%, 14.09%, 19.67% in patients with mild, moderate, severe and extremely severe CVH respectively, 7.09%, 17.29%, 19.13% and 27.27% in patients with a clinical course of CVH of 0.5-9 years, 10-19 years, 20-29 years, ≥30 years respectively. The most common clinical pattern was distal and lateral subungual onychomycosis (DLSO, 69.83%), followed by total dystrophic onychomycosis (TDO, 14.66%). Among the pathogenic fungi, dermatophytes amounted to 71.43%, yeasts 21.43%, moulds 7.14%, and Trichophyton rubrum was the most frequently isolated fungus (42.86%). Conclusions The incidence of onychomycosis in patients with CVH is correlated with the severity and course of CVH. Among these patients, the most common clinical pattern is DLSO with the most frequent fungal species being dermatophytes and predominant fungal isolate being Trichophyton rubrum.

Objective Ginger (Zingiber officinale) is widely used as a spice in cooking and as a medicinal herb in traditional herbal medicine. The present study was to investigate the analgesic and anti-inflammatory activities of ginger oil in experimental animal models. Methods The analgesic effect of the oils was evaluated by the acetic acid and hot-plate test models of pain in mice. The anti-inflammatory effect of the oil was investigated in rats, using rat paw edema induced by carrageenan, adjuvant arthritis, and vascular permeability induced by bradykinin, arachidonic acid, and histamine. Indomethacin (1 mg/kg), Aspirin (0.5 g/kg) and Dexamethasone (2.5 mg/kg) were used respectively as reference drugs for comparison. Results The ginger oil (0.25-1.0 g/kg) produced significant analgesic effect against chemically- and thermally-induced nociceptive pain stimuli in mice (P < 0.05, 0.01). And the ginger oil (0.25-1.0 g/kg) also significantly inhibited carrageenan-induced paw edema, adjuvant arthritis, and inflammatory mediators-induced vascular permeability in rats (P < 0.05, 0.001). Conclusion These findings confirm that the ginger oil can be used to treat pain and chronic inflammation such as rheumatic arthritis.

Objective: To evaluate the effect of ticagrelor on plasma P-selectin (CD62P) concentration during acute kidney injury in septic rats. Methods: Thirty SPF healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 180-220 g, were divided into 3 groups(n=10 each)using a random number table method: sham operation group (group S), sepsis group (group Sep) and ticagrelor group (group T). Sepsis was induced by cecal ligation and puncture in anesthetized rats.The abdomen was opened after anesthesia induction and then closed after turning the intestines in group S. Ticagrelor 8.6 mg/kg was given through a gastric tube into stomach at 12 h after establishing the model in group T, while the equal volume of distilled water was given instead in S and Sep groups.Blood samples were collected from hearts at 24 h after establishing the model for determination of the concentrations of Scr and plasma CD62P.The rats were then sacrificed, and bilateral renal tissues were taken for examination of pathological changes and for determination of cell apoptosis by fluorescence microscopy after Annexin/V-FITC double staining was performed. Results: Compared with group S, the concentrations of Scr and plasma CD62P, renal Paller score and apoptosis rate of renal cells were significantly increased in Sep and T groups (P<0.05). Compared with group Sep, the concentrations of Scr and plasma CD62P, renal Paller score and apoptosis rate of renal cells were significantly decreased in group T (P<0.05). Conclusion The mechanism by which ticagrelor reduces acute kidney injury is related to decreasing plasma CD62P concentrations and inhibiting cell apoptosis in septic rats.

BACKGROUNDTo express and purify human alpha3-integrin to serve as the antigen to prepare its antibody and to separate the Vero cell clones without expression of alpha3-integrin.

METHODSThe human alpha3-integrin gene was amplified by using RT-PCR, then subcloned into a pQE30 expression vector and expressed in E. coli. The gene expression was confirmed by Western blot assay. Rabbit was inoculated with purified antigen to stimulate the antibody generation. The target Vero cells were separated by negative selection using antibody plus complement mediated cytolysis. The separated cell clones were confirmed by immunofluorescence and Western blot assay.

RESULTSThe alpha3- integrin gene was cloned and expressed effetively, Western blot assay revealed that the expressed protein held good immune reactivity. High titer antibody was generated. However the expression of alpha3-integrin was not detected on Vero, VeroE6, Hep-2, 2BS and 293 cells.

CONCLUSIONSThe results of the study suggested that hantavirus has other receptors on Vero cells beside alpha 3-integrin.

Objective To investigate the relationship between various loop electrosurgical excision procedure (LEEP) margin status and residual high grade squamous intraepithelial lesion (HSIL) or worse at hysterectomy following conization. Methods The relevant clinicopathological data were collected in the Obstetrics and Gynecology Hospital, Fudan University from Jan. 2014 to Dec. 2015, including 947 cases who underwent hysterectomy within 6 months of LEEP. The residual HSIL or worse at hysterectomy were analyzed among the groups. (1) Clear margins, involved margins, and without 1 mm negative margins. (2) Only one positive margin, two positive margins and three positive margins. (3) A positive margin of internal ostium of cervix, of external ostium of cervix and of the basement. Results (1) The histological evaluation of the uterine specimens showed residual HSIL or worse in 234 cases (24.7％, 234/947). The proportion of residual lesions was 7.3％ (21/286) in population with clear margins, 33.2％ (211/635) with involved margins, 7.7％ (2/26) without 1 mm negative margins, respectively. The positive margins group had significant difference at the aspect of residual rate in contrast to the negative margins group and the without 1 mm negative margins group (P<0.01). Further studies conclusively showed that the proportion of residual lesions was very similar between the negative margins group and the without 1 mm negative margins group (P>0.05). (2) The involved margins were interpretable in 621 cases. This was detected in 25.3％(111/438) patients with only one positive margin, 47.4％(74/156) with two positive margins and 77.8％(21/27) among three positive margins, respectively (P<0.01). (3) Furthermore, there were 418 cases only one positive margin was definite, and the proportion of residual lesions was 31.0％(62/200) in population with a positive margin of internal ostium of cervix, 18.2％(31/170) of external ostium of cervix and 33.3％(16/48) of the basement. The residual rates were higher in the endocervical and basal margin groups than that in the ectocervical margin group, and the differences were significant (P<0.05). Conclusions The risk of residual HSIL or worse is significantly greater with involved margins at hysterectomy following LEEP. Both the positive endocervical and basal margin are excellent predictors of residual diseases, while the without 1 mm negative margin may be not. Clinicians should avoid treating it as positive margin and prevent overtreatment.
