OBJECTIVE To investigate the pattern of fungal isolates from hospital-acquired infection in tumor patients after chemotherapy. METHODS The clinical information of fungus isolates from 102 tumor patients after chemotherapy was investigated.We analyzed the risk factors,species and drug-resistance of isolates. RESULTS The lower respiratory tract and mouth infection accounted for 61.8% and 16.7% in 102 cases with fungal infection and 102 isolates were isolated from various clinical specimens.Among above 102 isolates,Candida albicans and C.tropicalis accounted for 71.6% and 14.7%.The resistant rate of C.albicans to fluconazole and miconazole were 96.2% and 61.4%,respectively. CONCLUSIONS Hospital-acquired infection resulted from fungi in tumor patients after chemotherapy is related to primary tumor,age,the amount of white cell and use of antibiotics.

Objective To determine the relationship between the polymorphism of D2S140 gene and type 2 diabetes mellitus.Methods D2S140 region polymorphism were analyzed with the polymerase chain reaction and short tandem repeat methods in 103 subjects with type 2 diabetes mellitus and 105 nondiabetic subjects.All subjects were biologically unrelated Chinese without a family history of DM.Results There were 7 alleles ranging from 151bp to 163bp in all subjects.The frequencies were 0.01 to 0.37,2 alleles were more common in diabetic patients than in nondiabetic subjects (RR=16.04, P

Objective To investigate the relationship between polymorphisms of candidate genes 〔glucokinase (GCK) gene, NIDDM1(D2S140) gene, fatty acid bindingprotein2(FABP2)gene〕and type 2 diabetes mellitus (DM) in Shandong Chinese Han population. Methods Short tandem repeat (STR) region polymorphisms of GCK gene, NIDDM1 gene and FABP2 gene were analyzed with the polymerase chain reaction and polyacrylamide sequencing gel in 107 patients with type 2 diabetes mellitus and 105 normal subjects. The subjects studied were unrelated and they are Chinese Hans living in Shandong province and no diabetes family history was revealed. Results A5 allele of GCK gene and B2 allele of NIDDM1 gene were positively related with type 2 diabetes (RR=15.70, P0.05). Logistic regression analysis showed that A5 allele and B2 allele were among the risk factors of type 2 diabetes. Conclusion Polymorphic microastellite repeat markers at the glucokinase gene and the NIDDM1 (D2S140) gene locus are associated with type 2 diabetes in Chinese. The polymorphism at the FABP2 locus is not a genetic marker for type 2 DM in Chinese Hans.

Objective To determine the value of ERCP and EST after Billroth gastroenterostomy. Methods ERCP was used in 31 patients after Billroth- Ⅰ gastroenterostomy, 12 of whom received EST. It was in 137 patients after Billroth-Ⅱ gastroenterostomy, of the 34 received EST and 4 EPBD.Results Billroth- Ⅰ gastroenterostomy ERCP was successfully performed in 28 out of the 31 patients and EST in 11 out of the 12 patients. Billroth- Ⅱ gastroenterostomy ERCP was successfully performed in 109 out of the 137 patients and EST in 31 out of the 38 patients. There were no serious complications in patients receiving endoscopic treatments. Concluasion The success rates of ERCP and EST are high in patients with bile duct lithiasis after Billroth-gastroenterostomy. Endoscopic treatment or cholangioduodenostomy has good therapeutic effects.

Objective To discuss the expression and significance of neutrophil to lymphocyte ratio(NLR) and platelet to lymphocyte ratio(PLR) in peripheral blood in patients with chronic obstructive pulmonary disease(COPD).Methods One hundred and fifty cases COPD patients who were treated in Respiratory Departments of Hai'an People′s Hospital Affiliated to Nantong University from January to December 2015 were selected and divided into stable period group with 60 cases and acute exacerbation period group with 90 cases,and 50 healthy subjects were selected as control group.Clinical data were collected and white blood cell count(WBC),neutrophil count(NC),lymphocyte count(LC),platelet(PLT),NLR,PLR,forced expiratory volume in one second(FEV1%) predicted and C reactive protein(CRP) were tested.Results NLR,PLR and CRP values were significantly higher in patients in acute exacerbation period group than in stable period group and control group(NLR:(10.30±9.93) vs.(6.76±5.90) vs.(5.85±3.67);PLR:(335.88±164.94) vs.(286.80±118.98) vs.(194.11±88.14);CRP: (42.18±24.89) mg/L vs.(23.27±13.59) mg/L vs.(22.49±13.47) mg/L,F=6.637,6.808,11.007,P<0.05),but FEV1% predicted was no difference in stable period group and acute exacerbation period group((58.85±16.83)% vs.(57.47±17.76)%;t=0.228,P>0.05).There was a significant positive correlation between NLR,PLR and CRP in acute exacerbation period group(r=0.374,0.379,P<0.01),there was a positive correlation between NLR and PLR(r=0.482,P<0.01),there was a negative correlation between NLR,PLR and FEV1(r=-0.297,-0.299,P<0.05).There was a significant positive correlation between NLR,PLR and CRP in table period group(r=0.593,0.433,P<0.01),NLR and PLR were also positively correlated(r=0.618,P<0.01),NLR,PLR and FEV1 accounted for the expected value of the negative correlation(r=-0.324,-0.342,P<0.05).Conclusion Both NLR and PLR are inflammatory markers,furthermore they show a significant negative correlation to airflow limitation in patients with COPD.

Objective To construct the lentiviral vector of RNA interference(RNAi) for DEK,and to detect its effect on breast cancer cell growth.Methods The DEK siRNA was designed and constructed based on DEK sequence using a lentiviral vector.The lentivirul vector containing DEK siRNA was named PSIH-H1-DEK as confirmed by PCR and sequenceing.PSIH-H1-DEK was then packaged with accessory plasmids into lentivirus in 293T cells and selected for 2 weeks with puromycin ( puro ) before the mixed colonies stably expressing DEK siRNA were obtained and the DEK expression was detected by real time PCR( RT-PCR) and Western blotting.The effect of DEK siRNA on ZR75-1 cell growth was determined by cell counting kit.Results Western blot and RT-PCR showed that PSIH-H1-DEK siRNA could suppress DEK gene expression.Suppression of DEK could markedly inhibit the growth of ZR75-1 cells.Conclusion The lentivirus-mediated DEK siRNA is obtained,which will facilitate further research on DEK function in breast cancer development.

Objective To investigate the causes of and prophylactic measure for complications of minilaparotomy cholecystectomy (MC).Methods The clinical data of 10 200 patients receiving MC from Apri1 1991 to March 2006 were analyzed.Results MC was successful in 9 835 cases(96.4%), and in 365 cases(3.6%) the incision was lengthened. Serious complications were 12 cases(0.12%)of bi1e duct injury, 4 cases(0.04%)of colon injury, 8 cases(0.08%)of massive haemorrhage, and 25 cases (0.25%)of bile leakage. Four 4 cases(0.04%) died. Conclusions The key to prevention of complications is a strict selection of MC indications,careful identification of the anatomical structures of Calot's triangle,use of suture ligation of the mesentery of gallbladder triangle and the technique of deep knot-tying and the timely use of extension of the incision.
