ObjectiveTo evaluate the therapeutic effect of encircling constriction of superficial femoral vein in the treatment of primary deep venous insuficiency(PDVI).MethodsFrom Jan.2004 to Jun.2011,187 patients( 196 lower extremities)with primary deep venous insufficiency were treated with encircling constriction of venous wall at the first pair of superficial femoral venous valve pulse superficial varicose stripping.Results The 183 limbs in 176 patients were followed-up from 7 months to 8 years,with a mean period for 63.5 months.Ninety-four point one percent of the patients were followed up (176/187).Clinical symptomatic improvement achieved in 87.4％ ( 160/183 ) of the lower extremities.There was 2.2％ ( 4/183 ) of recurrence of the varicose vein,9.3％ ( 17/183 ) of light edema,8％ ( 2/25 ) of recurrence of ulcer.ConclusionEncircling constriction of superficial femoral vein is an effective method in the treatment of primary deep venous valve insufficiency.

Aim To prepare and characterize a monoclonal antibody against recombinant glutathione S-transferase(GST) for purifying GST fusion protein. Methods The GST-follistatin fusion protein was expressed by using a pGEX4T-1 expression vector in Escherichia coli BL21 and purified by glutathione-resin affinity column chromatography. Then female Balb/c mice were immunized with the GST-FS, The immunized splenocytes were fused with NS-1 hybridoma cells. Dreparation of the mAb was used by conventional hybridoma techniqal. The mAb purified by protein A, was culpled with Sepharose4B to purify further GST fusion protein by affinity chromatography. Results The SDS-PAGE showed that the GST fusion protein could be purified effctively by specific mAb affinity chromatography as same as by glutathione-resin affinity chromatography. Conclusion mAb affinity chromatography will be a ecnomical and useful method and it can be used for secondary purification of GST fusion protein following glutathione-resin affinity chromatography.

Objective To evaluate endoscopy for the diagnosis of primary gastrointestinal mucosaassociated lymphoid tissue lymphoma (MALT lymphoma) and diffuse large B-cell lymphoma (DLBCL).Methods The clinical pathology,hematological/biochemical studies,and endoscopic data of 98 primary gastrointestinal MALT lymphoma and DLBCL patients from Aug 2010 to May 2017 were analyzed retrospectively.Results 17 patients had higher than normal LDH blood level (＞270 U/L).47 patients were Helicobacter pylori (Hp) positive;Gastrointestinal endoscopic study,including endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) and endoscopic ultrasonography established diagnosis of MALT lymphoma and DLBCL in 96 out of 98 cases (98％).The endoscopic manifestations of MALT lymphoma and DLBCL were ulcerative,uplift,diffuse and infiltrative,and erosive,with ulcerative type as the dominant one.The follow-up examination showed that the survival ratio (88％) of MALT patients was higher than that of DLBCL(68％),and more patients with lower Ann Arbor stage survived (92％) than those with higher Ann Arbor stage (64％).Conclusion Endoscopic biopsy together with endoscopic ultrasonography makes definite diagnosis of MALT and DLBCL.

Objective To analyze the relevance between the consumption of various antimicrobials and antimicrobial re-sistance of Acinetobacter baumanni in a grade three hospital during 2007 -2010 .Methods A retrospective analysis was per-formed to count and sort the defined daily doses (DDDs) and the consumption of various antimicrobials in the hospital between 2007 and 2010 .Meanwhile the resistance rates of Acinetobacter baumanni to different antimicrobials were collected in the same period .Data was analyzed by SAS 8 .2 statistical software package using Spearman correlation method .Results The resistance rate of Acinetobacter baumanni to imipenem was significantly positively correlated with the consumption of carbapenems (r=0 .954 6 ,P<0 .01) ,it is positively correlated with the dosage of imipenem (r=0 .849 2 ,P<0 .05) ,it is also significantly posi-tively correlated with the consumption of meropenem (r=0 .999 2 ,P<0 .05) ,and the consumption of amoxicillin/clavulanate potassium ,respectively(r=0 .800 5 ,P<0 .05) .There was no correlation between the resistance rate of Acinetobacter bauman-ni and the dosage of aminoglycosides ,fluoroquinolones ,even β-lactamase inhibitors(P>0 .05) .Conclusion The use of car-bapenems should be correlated with their indications strictly ,only applying to severe infection of Acinetobacter baumanni .The aminoglycosides of amikacin and β-lactamase inhibitors of cefoperazone/sulbactam are the better options to treat A cinetobacter baumanni infection .

Objective To investigate the factors affecting the incidence of epilepsy after cranioplasty.Methods A retrospective case control study was conducted on the clinical data of 171 patients with skull defect who underwent cranioplasty between January 2012 and December 2015.There were 126 males and 45 females,with an average age of 50.9 years (range,16-78 years).The patients were divided into epileptic seizure group (61 cases) and non epileptic seizure group (110 cases).The gender,age,defect cause,defect location,defect duration,perioperative antiepileptic drug use,skull defect regional depression volume (Vd),skull defect regional integrity volume (Vf),skull defect regional depression rate (Pd) of two groups were recorded.Univariate analysis and multivariate logistic regression analysis were used to identify the independent risk factor of epilepsy after cranioplasty.Results All patients were followed up for 54 months averagely (range,18-90 months).Sixty-one patients (35.7％) had epilepsy after cranioplasty.Univariate analysis suggested that age,defect cause,defect location,defect duration,perioperative antiepileptic drug use,and Vf were not associated with epilepsy after cranioplasty (all P ＞ 0.05);while gender,Vd,and Pd was associated with epilepsy after cranioplasty (P ＜ 0.05).Multivariate logistic regression analysis demonstrated that Pd (OR =0.024,95％ CI 0.001-0.502,P ＜0.05) was independent predictor of epilepsy after cranioplasty.Conclusion Pd is an independent risk factor for epilepsy after cranioplasty and depression degree could significantly affect its incidence.
