Knowing the causes and taking rational nursing helped to raise the survival rate and quality of life after OLT.

Objective To make contrast analysis of sleeve lobectomy and wedge resection in lung cancer treatment by observing the clinical curative effect.Methods 100 patients with lung cancer using random table method, all the patients were divided into the observation group ( 50 cases, treated with sleeve resection ) , control group (50 cases,treated with wedge resection),follow-up after treatment lasted respectively for 3 years.Results In the two groups,anastomotic fistula incidence and mortality rates of the observation group were 4%,6%;6% and 8% in the control group,there were no statistical difference (χ2 =0.00,0.00,all P>0.05);the positive rate of stump cancer cell bronchial in the observation group was 4%,it was obviously less than 16% in the control group,and the differ-ence was obvious (χ2 =4.00,P<0.05) .The anastomotic scar tissue hyperplasia and recurrence rate of the observa-tion group during the follow-up period were 2%,2%;which were lower than 16%,18% of the control group (χ2 =4.40,7.11,all P<0.05).The 1,3 year survival rates of the observation group were 92%,64%,which were higher than 62%and 42%of the control group (χ2 =12.70,4.86,all P<0.05).Conclusion Taking sleeve resection for bronchogenic carcinoma can effectively control the positive rate of bronchial stump with cancer cells,inhibit anasto-motic scar tissue hyperplasia,reduce the recurrence rate,and the curative effect is very good,which is worth of clinical application.

Objective To investigate molecular typing and drug resistance patterns of 98 Klebsiella pneumoniae (K.pneumoniae) isolated from type 2 diabetes patients complicated with maxillofacial infection,to research the virulence and resistance mechanisms.Methods The study was a prospective study that adopted the method of continuous sampling from fixed location,from March 2010 to October 2012.The maxillofacial surgery patients diagnosed with type 2 diabetes complicated with maxillofacial infection were chosen in 7 hospitals in Zhengzhou as the research object,and a total of 431 pus sample were collected continuously,in which 98 strains K.pneumoniae were isolated and identified.The Kirby-Bauer disk diffusion test was conducted in 98 strains to determine the resistance to 19 antibacterial agents.K.pneumoniae chromosomal DNA were digested by restriction endonuclease Xba Ⅰ and analyzed by pulsed-field gel electrophoresis (PFGE).PFGE patterns of K.pneumoniae strains were analyzed using Fingerprinting software.The relationship between the molecular types and resistance phenotype was observed.The extended spectrum β-1actamase-producing K.pneumoniae were screened out by the double disc synergy test (DDST)Polymerase chain reaction (PCR) was used to detect resistant genotypes,serotype and virulence genes.The purified PCR products of resistant genes were cloned and sequenced.Hypermucoviscosity phenotype of all strains were determined by string test.Results Much severer drug-resistance for K.pneumoniae was identified and the result of extended-spectrum beta-lactamase producing rate was 57.1 ％.Ninety-eight strains were dispatched into 13 groups by PFGE.No dominant bands and specific extended-spectrum beta-lactamase DNA bands were found.The results of PCR showed that among the 56 strains of extended spectrum β-lactamase-producing K.pneumoniae,40 were positive for blaSHV (accounting for 71.4％),28 positive for blaTEM (accounting for 50.5％),21 positive for blaCTX-M (accounting tor 37.5％).The sequencing results were as follows:TEM-1,CTX-M-3 and a variety of SHV.Serotype K1,K2,K3,K5,K20,K54 and K57 and 3 kinds of virulence genes were detected,but not in strong toxicity-based.Hypermucoviscosity positive rate was 31.6％ (31/98).Conclusion Much severer drug resistance of K.pneumoniae in this study was identified and resistant mechanism was complex,in which strong toxicity serotype and virulence geues exist,which need more attention from clinical.

Background Posterior capsular opacification (PCO) is a primary cause of blurred vision after extra-capsular cataract extraction (ECCE),and there is a higher incidence of PCO in the patients with diabetes mellitus.Echistatin (Ecs) can suppress the proliferation of lens epithelial cells (LECs) and thereby inhibit the formation of PCO.However,its mechanism and safe dose deserve to study.Objective The aim of this study was to observe the inhibitory effect of different concentrations of Ecs on LECs proliferation in the early stage of PCO in diabetic rabbits and explore the safe dose of Ecs.Methods Diabetic mellitus was induced by injection of 90 mg/kg alloxan via ear vein in 15 New Zealand white rabbis.ECCE was performed in the right eyes of the rabbits.The rabbits were randomized to the control group and 5.0,7.5,10.0 and 15.0 μg/ml Ecs group according to randomized number table method.Ecs of 0.2 ml in above doses was injected into the anterior chamber after ECCE in different concentrations of Ecs groups,and 0.2 ml distilled water was used in the same way in the only diabetic rabbits as the control group.Postopeartive response of ocular anterior segment was observed and PCO was graded under the slit lamp microscope.The corneal and retinal specimens were prepared 10 days after operation for the assay of preliferative cell nuclear antigen (PCNA) expression in LECs by immunochemistry to evaluate the effective dose of Ecs.Regular histopathological examination was performed,and apoptosis of corneal endothelial cells and retinal cells was detected by TUNEL method to assess the safe concentration of Ecs.Results Different degrees of corneal edema and exudation in anterior chamber were seen in the eyes of different groups.The inflammatory response disappeared 3-5 days in the control group and 5.0 μg/ml Ecs group and 7 days in the ≥7.5 μg/ml Ecs groups.PCO was 1-2 grade in the control group and 5.0 μg/ml Ecs group and 0 grade in the ≥ 7.5 μg/ml Ecs groups.The difference in the positive expression level (absorbance,A) for PCNA in LECs was significantly different among the control group and various Ecs groups (F=18.006,P=0.001),and the positive expression level of PCNA in the ≥ 7.5 μg/ml Ecs groups was markedly reduced in comparison with that in the control group (P =0.010,0.001).Hematoxylin and eosin staining showed an normal morphology and order arrangement in corneal endothelial cells and intact structure in retinal internal limiting membrane in the groups.TUNEL assay revealed that the apoptosis values (mean A value) of corneal endothelial ceils and retinal cells in the ≤ 10.0 μg/ml Ecs groups were not significantly changed in comparison with the control group (all at P＞0.05),but the apoptosis values in the 15.0 μg/ml Ecs group were markedly higher than those in the control group (P=0.004,0.018).Conclusions Ecs can inhibit the early PCO in diabetic rabbits and show the optimal effect at the concentrations of 7.5 and 10.0 μg/ml without visible eytotoxicity to eye other tissues.Therefore,these two doses of Ees might be used for the study of long-term therapeutic effectiveness.

[Objective]To investigate the prognostic value of 18F-FDG PET/CT with different metabolic parameters in newly diagnosed limited-disease(LD)small cell lung cancer(SCLC).[Methods]Retrospective analysis was carried out in the patients between June 2005 to December 2016 in our hospital confirmed of LD SCLC by pathology or cytology and comprehensive imaging. Fifty-four patients were recruited. Record the general characteristics of patients,pre-treatment KPS score,smoking status,weight loss,serum LDH,NSE,OS,PFS. All lesions(primary lesions + metastases)were sketched out within one VOI,and the SUVmax, SUVmean and SUVpeak in the VOI were automatically measured and recorded. The automatic measurement was performed by the fixed threshold method. The thresholds of tumor of MTV and TLG were 40% and 50% of SUVmax. The TLG and MTV were identified as TLG40%,TLG50%,MTV40% and MTV50% respectively. Kaplan-Meier method was used for survival analysis. All the prognostic factors were analyzed by Cox model.[Result]The median SUVmax was 13.92(2.61~43.28),the median of SUVmean was 8.31(1.71~26.85) and the median of SUVpeak was 10.51(1.49 ~ 27.48). The median of TLG40% was 340.22(16.58 ~ 2827.26),the median of TLG50%was 215.645(1.70 ~ 2270.36),the median of MTV40% was 36.71(1.15 ~ 259.47 cm3),the median of MTV50% was 19.65(0.93 ~1900.00)cm3. Univariate and multivariate analysis of metabolic index and prognosis showed that TLG50% was the prognostic factor of OS(P = 0.013),but not of PFS(P > 0.05). The SUVmax,SUVmean and SUVpeak were not the prognostic factors of OS and PFS(P >0.05).[Conclusion]The volume metabolic parameters TLG50%was the independent prognostic factor of the overall survival time of the LD SCLC. The volume metabolic parameters (TLG and MTV) of 18F-FDG PET/CT were related to the prognosis of SCLC ,which could provide the basis for individual chemotherapy.
