Objective To explore the feasibility and safety of Mckeown-type minimally invasive esophagectomy in para-recurrent laryngeal nerve lymphadenectomy. Methods A total of 163 cases underwent minimally invasive McKeown resection for esophageal carcinoma in the Affiliated Tumor Hospital of Xinjiang Medical University were retrospectively analyzed. Patients were divided into routine treatment group (n=63), right recurrent nerve lymph node dissection group (right group, n=53) and bilateral recurrent laryngeal nerve lymph node dissection group (bilateral group, n=47) according to the operation modes. The postoperative pathology, operation time, intraoperative bleeding volume, postoperative hospitalization time, number of lymph nodes and pneumonia, anastomotic fistula, laryngeal nerve injury and other complications were compared between three groups of patients. Pathological conditions were consisted of the location of tumor, the degree of differentiation, T stage and pathological stage. Postoperative complications were followed up for 6 months. Results There were no significant differences in tumor location, pathological differentiation degree, T stage and pathologic stage between three groups. The amount of bleeding was more in the routine group than that of the right group and the bilateral group (P<0.05). There was no significant difference in the amount of bleeding between the right group and the bilateral group. The total lymph nodes and thoracic lymph nodes were increased in order in routine group, the right group and the bilateral group, and there was significant difference between three groups(P<0.05). There were no significant differences in other operation data and complications between three groups. Conclusion McKeown-type minimally invasive esophagectomy shows good feasibility and safety for para-recurrent laryngeal nerve lymphadenectomy .

Background Herpes stromal keratitis (HSK) is a common infectious ocular surface disease,with a higher recurrent rate,especially in necrotizing HSK.The diagnosis of HSK primarily depends on signs and symptoms,and specific laboratory diagnostic is lack.Objective This study was to clarify the expression of herpes simplex virus (HSV) in the corneal epithelium scrapings and tears of necrotizing HSK patients.Methods Thirty eyes of 30 patients with necrotizing HSK were enrolled in Nanjing Hospital of Nanjing Medical Hospital from September 2012 to September 2013 under the patient's informed consent.The eyes were examined by slit lamp microscope and scored.HSK patients received local and systemic therapy for 8 weeks and then an oral maintenance dose for 6 months.Corneal epithelial scrapings and tears samples were collected for HSV DNA detection by real-time PCR before and the 1 st,2nd,4th,6th and 8th week after therapy respectively.The difference of HSV positive rate was compared between corneal epithelium scrapings and tears samples using Chi-square test.Multilevel mixed effective model was employed to evaluate HSV concentration change in the samples at various time points in the HSV-positive patients of initial visit.The correlation between HSV concentration and clinical score was analyzed by Spearman rank correlation.Results HSV-positive rate was 46.4％ (13/30) in the corneal epithelial scrapings and 13.3％(4/30) in the tear samples,showing a significant difference between them (P =0.006).HSV-positive rate was significantly lower in the corneal epithelial scrapings 1 week,2 weeks and 4 weeks after treatment than before (P =0.001,0.003,0.004),and no HSV was detected 6 weeks and 8 weeks after treatment.No significant change in HSV-positive rate in tear samples in 1 week and 2 weeks after treatment in comparison with before treatment (P =1.000,0.583),and no HSV was detected after 4 weeks following treatment.The HSV concentration was 2460 (2 165-636500)/ml in initial 13 HSV-positive eyes of corneal epithelial scrapings and 0 (0-1150)/ml in initial 13 HSV-positive eyes of tear samples.Multilevel mixed effective model determined that HSV concentration was significantly lower in corneal epithelial scraping than that in tear (P =0.005),and HSV concentration was reduced with the lapse of time (P =0.001),with the faster rate of decline in the corneal epithelial scrapings (P =0.049).A positive correlation was found between initial HSV concentration and clinical scores (rs =0.844,P =0.000).Conclusiors Real-time PCR appears to be a powerful molecular tool for the detection of HSV in the HSK,especially in corneal epithelial scrapings of lesion.The initial positive outcome of viral DNA in corneal epithelial scrapings predicts a severe clinical procedure.

Objective To investigate the expression levels of interferon-inducible genes (IFIT1,IFIT4,OAS1,OASL,ISG15) in the peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus(SLE).and the relations between these genes expression levels and disease activity are explored.Methods Sybr green dye based real-time quantitative PCR method was used to detect the expression levels (indicated as-△△Ct value) of WIT1,IFIT4.OAS1,OASL and ISG15 in 76 patients with SJJE and 54 controls.Their expression levels were compared with erythroeyte sedimentation rate (ESR),serum C reactive protein (CRP),complement C3,C4.antinuclear antibody (ANA).anti-double stranded DNA antibody.The associations between the expression levels of IFIT1,IFIT4,OASI.OASL,ISG15,ESR,CRP,complement C3,C4,ANA,anti-double stranded DNA antibody and SLEDAI scores in patients with SLE were analyzed.Results ① The expression levels of WIT1,IFIT4,OAS1,OASL and ISG15 in the SLE patients were significantly higher than those of the normal controls (P＜0.01).The expression levels of IFIT1,IFIT4,OAS1,OASL and ISG15 in active SLE patients were higher than those of inactive SLE patients (P＜0.05).The real time expression levels of IFIT1,IFIT4,OAS1.OASL and ISG15 showed positive correlations with each other (r＞0.5,P＜0.05) in patients with SLE.② The expression levels of IFIT1,IFIT4,OAS1,OASL and ISG15 were positively correlated with the SLEDAI scores (r＞0.5,P＜0.05).③ There was no correlation between ESR,CRP,complement C3,C4,ANA and the expression levels of IFIT1,IFIT4,OAS1,OASL,ISG15,SLEDAI scores except anti-double stranded DNA antibody (r＞0.5.P＜0.05).Conclusion The expression levels of IFIT1,IFIT4,OAS1,OASL and ISG15 in patients with SLE are significantly higher than those of the normal controls,and positively associated with SLEDAI scores,so they are helpful in evaluating SLE disease activity and severity.IFIT1,IFIT4,OAS1,OASL and ISG15 genes may be the potential treating targets for SLE.
