Objective To study the postoperative survival rate of elderly patients with hip fracture at different time and its related factors.Methods We conducted the follow-up studies of 255 elderly hip fracture patients from June 2008 to June 2011 in our hospital.The survival rates of patients at 6 months,1,2 and 3 years after operation and their related factors were studied.Results The survival rate was 96.5％,89.8％,78.0％ and 69.4％ at 6 months,1,2 and 3 years after operation respectively in 255 elderly hip fracture patients.Survival analysis showed that many kinds of preoperative comorbidities,low albumin level,old age and severe anemia were the risk factors for survival.Good activity of daily living before injury was a protective factor for survival.Gender,fracture type,the American Society of Anesthesiologists (ASA) classification,time from injury to surgery,anesthesia type,surgical approach,operative time,blood loss and hospital stay periods had no effect on survival after operation.Conclusions The survival rate in elderly patients with hip fracture after surgery is affected by many factors.Preoperative comorbidities,anemia and hypoalbuminemia should be actively treated,the activity of daily living should be improved by the directed therapy and rehabilitation,in order to improve the survival rate in elderly patients with hip fracture.

Objective To validate the effect of Renji acute kidney injury score (RAKIS) on predicting patients with acute kidney injury (AKI) after cardiac surgeries,and make comparison with Cleveland score,simplified renal index (SRI) and acute kidney injury following cardiac surgery (AKICS).Methods Patients undergoing open heart surgery from 2008/01/01 to 2010/10/31 in Renji hospital were enrolled,and their scores of those four scoring models were calculated.AKI patients were diagnosed by KDIGO,and those scores of AKI patients and non-AKI patients were compared.Receiver operating characteristic (ROC) curve and area under curve (AUC) were used to decide the predictive values of those models.Results A total of 1126 patients were chosen in this cohort,with the average age of (58.43±14.88) years (rang from 18 to 88).The male to female ratio was 1.47:1.And 355(31.5％) patients were developed AKI.AKI stage Ⅰ,Ⅱ and Ⅲ were 65.4％,23.7％ and 11.0％ respectively.RAKIS was significantly higher in AKI patients than in non-AKI patients (17.5 vs 9.0,P ＜ 0.001).The AUCs of RAKIS to predict AKI,AKI Ⅱ-Ⅲ stages,renal replacement therapy (RRT)and in-hospital death were 0.818,0.819,0.800 and 0.784 respectively.The AUCs of Cleveland score and SRI were 0.659 to 0.710,lower than those of RAKIS and AKICS.AKICS had lower value for predicting AKI and AKI Ⅱ-Ⅲ stages (AUC 0.766 and 0.793),but good value in predicting RRT and inhospital death after surgery (AUC 0.804 and 0.835) as compared with RAKIS.Conclusions RAKIS is valid and accurate in the discrimination of KDIGO defined AKI patients,while for predicting the composite end point,AKICS may be more useful.

BACKGROUNDCandida albicans is the most frequently seen opportunistic human fungal pathogen. Terbinafine is an allylamine antifungal agent that has been proven to have high clinical efficacy in the therapy of fungal infections, the mechanism of action of terbinafine involves the specific inhibition of fungal squalene epoxidase, resulting in ergosterol deficiency and accumulation of intracellular squalene. We used cDNA microarray analysis technology to monitor global expression profile changes of Candida albicans genes in response to terbinafine treatment, and we anticipated a panoramic view of the responses of Candida albicans cells to the representatives of allylamine antifungal agents at the molecular level in an effort to identify drug class-specific and mechanism-independent changes in gene expression.

METHODSCandida albicans strain ATCC 90028 was exposed to either medium alone or terbinafine at a concentration equivalent to the 1/2 minimal inhibitory concentrations (MICs, 4 mg/L) for 90 minutes. RNA was isolated and gene expression profiles were compared to identify the changes in the gene expression profile using a cDNA microarray analysis. Differential expression of 10 select genes detected by cDNA microarray analysis was confirmed by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSA total of 222 genes were found to be responsive to terbinafine, including 121 up-regulated genes and 101 down-regulated genes. These included genes encoding membrane transport proteins belonging to the members of the ATP-binding cassette (ABC) or major facilitator superfamily (MFS; CDR1, AGP2, GAP6, PHO84, HOL3, FCY23, VCX1), genes involved in stress response and detoxification (CDR1, AGP2, HOL3), and gene involved in the ergosterol biosynthesis pathway (ERG12). The results of semi-quantitative RT-PCR were consistent with that of the cDNA microarray analysis.

CONCLUSIONSThe up-regulation of the gene encoding the multidrug resistance efflux pump CDR1 may contribute to the terbinafine resistance in Candida albicans. However, the precise roles of other affected genes remain unclear, further studies of these genes and their respective products that play roles in the context of antifungal resistance are warranted.

BALB/c mice were immunized with purified White spot syndrome virus (WSSV).Six monoclonal antibody cell lines were selected by ELISA with VP28 protein expressed in E.coll in vitro neutralization experiments showed that 4 of them could inhibit the virus infection in crayfish.Westernblot suggested that all these monoclonal antibodies were against the conformational structure of VP28.The monoclonal antibody 7B4 was labeled with colloidal gold particles and used to locate the VP28 on virus envelope by immunogold labeling.These monoclonal antibodies could be used to develop immunological diagnosis methods for WSSV infection.

Objective: To identify the relationship between Dietary Diversity and Nutritional Status in Elderly Inpatient. Methods: 136 elderly inpatients were selected in a tertiary hospital in Yunnan Provience. Food frequency questionnaire was used to collect dietary information and DDS9 was calculated; We used Mini Nutritional Assessment (MNA) to evaluate nutritional status, then analyzed the effect of Dietary Diversity on nutritional status in elderly inpatients. Results:① Patients at risk of malnutrition and with confirmed malnutrition in participants were 46. 3％, 33. 8％,, respectively. ② The incidence of insufficient diversity, moderate diversity and adequate diversity were 19. 9％, 77. 2％ and 2. 9％, respectively; the total scores of dietary diversity were (4. 68 ± 1. 27). However, apart from vegetables, the rest 8 kinds of food all showed lower scores of intra-group variety; while the consumption of beans, nuts and seafood was seriously inadequate. ③ The incidence of malnutrition risk and confirmed malnutrition in insufficient-diversity group and moderate-diversity group were 5. 109 times and 1. 094 times of adequacy group (P＜ 0. 05). Conclusion: Dietary diversity is strongly associated with putritional status in elderly inpatient. Improvement of dietary diversity status is potentially beneficial in the prevention of malnutrition.

Scm in volume(42/60),multiple site involvement(44/60),blood type"O"(31/41),in comparison with those of survival group,and the difference was statistically significant.C-erbB-2,p16,p53,P-gp,CD_(44) and CD_(25)expression were not significantly different in these two groups. Conclusion The clinical stage, lymph node metastasis,lymphatic tumor emboli and/or neural involvement,infiltration depth,histological dif- ferentiation,tumor volume,involvement extension are important prognostic factors in patients with gastric can- cer,while the significance of cancer-related gene expression in gastric carcinomas needs to be studied further.

The aim of this study was to investigate the clinical value of fluorescence in situ hybridization (FISH) in detecting the genomic aberration of chronic lymphocytic leukemia (CLL). FISH was used for 32 patients who were newly diagnosed as CLL. Five types of fluorescence probes with labeled DNA probes were included as sequence specific probes D13S25 for 13q14.3, P53 for 17p13.1, ATM for 11q22.3, RB1 for 13q14 and chromosomes 12. Meanwhile, FISH was used to detect IGH/CCND1 fusion gene in 10 CLL patients with untypical immunophenotypes. The results showed that out of 32 patients, 26 cases (81.3%) were abnormal including 14 cases of D13S25 deletion, 11 of RB1 deletion, 9 of trisomia 12, 6 cases of P53 deletion, and 1 of ATM deletion. 12 cases showed 1 kind of genomic aberration, including 7 cases of trisomia 12, 3 cases of D13S25 deletion, 1 of P53 deletion, 1 of ATM deletion. 11 eases displayed 2 kinds of abnormalities. Out of 11 cases, 7 were D13S25/RB1 deletion, 4 were of P53 deletion, and 3 cases had 3 kinds of abnormalities. Among 10 patients with CD5(+)CD23(-), two were positive with IGH/CCND1. It is concluded that the FISH can improve the detecting of chromosomal abnormalities in CLL, and every abnormality has its special feature. Detection of IGH/CCND1 seems important in diagnoses of CLL.
