OBJECTIVE: To evaluate the effectiveness of the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire in measuring the quality of life in patients with primary hepatic carcinoma (PHC) in China. METHODS: FACT-Hep questionnaire was translated into Chinese and revised properly. From September 2005 to April 2006, one hundred and eighty patients with primary liver carcinoma were admitted and measured by using the Chinese version of FACT-Hep questionnaire, and the reliabilities, validities and responsibilities of the questionnaire were assessed. RESULTS: Correlation coefficient was higher between items and dimension of their corresponding domain (0.5933+/-0.1652) than that between the items and other domains (0.2749+/-0.1922). Six principal constituents were extracted by factor analysis and represented all domains of the questionnaire. The combinations of components were consistent with what was expected. The correlation coefficient of criterion-related validity was 0.828. The test-retest reliability correlation coefficients of physical, social/family, emotion, function, symptom and total questionnaire were 0.731, 0.334, 0.953, 0.786, 0.785 and 0.801 respectively, and the values of Cronbach's alpha were 0.7397, 0.4193, 0.7914, 0.8250, 0.8399 and 0.9161, respectively. There were statistical differences in scores of FACT-Hep questionnaire in different PHC stages or in different Child-Pugh classes (P<0.05). CONCLUSION: The FACT-Hep questionnaire can measure the quality of life in patients with PHC with good reliability, validity and responsiveness; it can be used in assessing the disease-specific health-related quality of life of patients with hepatobiliary cancers.

BACKGROUND:Recently, a neuroprotective effect of granulocyte colony-stimulating factor was reported in a model of cerebral infarction and a model of acute spinal cord injury. However, the applied animal model was not established by impact method, different from pathophysiological process of human.
OBJECTIVE:To observe effects of granulocyte colony-stimulating factor on motor function in a rat model of spinal cord injury induced by Al en’s method.
METHODS:Wistar rats were used to establish spinal cord injury at T 10 level using modified Al en’s method. They were randomly assigned to two groups, granulocyte colony-stimulating factor group, treated with granulocyte colony-stimulating factor, and vehicle group, treated with equal volume of PBS. The motor function was evaluated with Basso-Beattie-Bresnahan score and modified Rivlin loxotic plate test monitored at 1, 7, 14, 21, 28 and 35 days, and four-limb muscle strength was assessed using Grid walk test at 7, 14, 21, 28 and 35 days post-operatively.
RESULTS AND CONCLUSION:Hind limbs paralysis occurred in al animals postoperatively. Scores of Basso-Beattie-Bresnahan and modified Rivlin loxotic plate test were greater in granulocyte colony-stimulating factor group compared with vehicle group at 7, 14, 21, 28 and 35 days (P<0.05-0.01);mean Grid walk test errors were less in granulocyte colony-stimulating factor group compared with vehicle group at 14, 21, 28 and 35 days (P<0.05-0.01). Results indicate that motor function and four-limb muscle strength were improved fol owing granulocyte colony-stimulating factor therapy compared with vehicle group, indicating that granulocyte colony-stimulating factor has a positive effect on spinal cord injury.

Objective To investigate the different influencing on the healing of anastomotic stoma between two kinds of alimentary canal reconstruction after laparoscopic radical resection of low rectal cance.Methods The clinical data of July 2013 -January 2016 suffering from stage Ⅱ -Ⅲ low rectal cancer and in our hospital underwent laparoscopic colorectal cancer radical surgery patients was retrospectively analyzed.Through accessing to medical records,the patients of diabetes,hypoproteinemia,malnutrition,preoperative uncorrectable cases and received neoadjuvant therapy were excluded.More than a total of 59 cases were enrolled,34 cases of them received traditional alimentary canal reconstruction(traditional group,including 26 cases of low rectal cancer,8 cases of super low rectal cancer,also 21 cases of them in stageⅡand 13 cases in stage Ⅲ),25 cases of them received anal anastomosis resection (including 18 cases of low rectal cancer,7 cases of super low rectal cancer,also 20 cases of them in stage Ⅱ and 5 cases in stageⅢ).Results In the traditional group,1case of 34 patients with anastomotic leakage,3 cases of anastomotic bleeding, while in the improved group,2cases of 25 patients with anastomotic leakage,2 cases of anastomotic bleeding.There was no significant difference in the incidence of anastomotic leakage and anastomotic bleeding between the two groups (3cases vs.2cases,1case vs.2cases,χ2 =0.13,0.75,all P >0.05).All cases did not occur in patients with anastomotic stenosis,and all patients were cured and discharged.Conclusion Each of the two methods have their advantages and disadvantages.Through preoperative,intraoperative evaluation of tumor status,reasonable choice of tumor treatment and anastomosis,is more conducive to postoperative recovery.

Objective To observe the therapeutic effect of Shilin Qinghua Decoction(SQD) for the treatment of urinary calculi.Methods Two hundred urinary calculi patients were equally randomized into two groups: the treatment group received SQD(mainly composed of Herba Lysimachiae,Endothelium Corneum Gigeriae Galli,Radix Paeoniae Alba,Talcum,Radix Clematidis,Poria,Semen Vaccariae,Herba Plataginis,Herba Polygoni Avicularis,Herba Dianthi,Succinum powder),and the control group received uralyt.Twenty days constituted one treatment course,and the treatment lasted 1～3 course(s) according to the illness state.The therapeutic effect was evaluated after 2 months.Results The total effective rate was 96.0% in the treatment group and 81.0% in the control group,the difference being obviously significant(P

Objective To compare the efficacy of self-made bone cement spacers containing vancomycin(vancomycin spacer)and Link infection-treating spacers(Link type spacer)for chronic infection after total hip arthroplasty(HTA)and investigate the choice of spacers for the two-stage revision of infection.Methods The study included 26 patients with infection combined with HTA,aged 32-82 years(mean 69.5 years).In the first stage,after complete debridement and removal of infected prostheses,the vancomycin spacers were implanted in 14 patients,while the Link type spacers were implanted in the rest 12 patients.Two weeks of intravenous administration of antibiotics and then six weeks of oral administration of antibiotics were done postoperatively.White blood cells(WBCs),erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP)were measured periodically after operation.THA revision was performed in the second stage.Clinical outcomes were evaluated according to the pre-and post-operative Harris hip score.Results All patients obtained primary healing of incision after complete debridement,removal of prostheses and implant of the vancomycin spacers or the Link type spacers.Two-stage revision surgery was performed at 3-11.5 months after the one-stage surgery(mean 5.2 months).The follow-up ranging from 12 to 33 months(mean 20.8 months)manifested no signs of reinfection.The mean Harris hip score was increased from 27.9 points before one-stage operation to 52.9 points before two-stage operation,and 83.6 points at the latest follow-up(P＜0.05)One of 12 vancomycin spacers was broken before the revision surgery,as was free from the Link spacers.Conclusions(Ⅰ)Two-stage revision is an effective method in the treatment of infection after HTA because of high eradication rate of infection,effective pain relief and good postoperative functional result.(2)The vancomycin spacers and the Link type spacers can both effectively control infection and restore part of limb function.(3)The Link type spacers take advantages of simple in operation and the function improvement of the limbs during the intermittent period of treatment,but disadvantages of the catheters being prone to block,limited slow release of antibiotics and high cost of treatment.Thereby,the Link type spacer is suitable for the patients with relatively strong constitution,little serious infection,or high requirement of limb functions at the interval of two operations.

Thioesterase catalyzes the hydrolysis of acyl-ACP and saturated fatty acyl chain. It plays a key role in the accumulation of medium chain fatty acids in vivo. In this study, to construct an engineering strain to produce MCFAs, the Arabidopsis acyl-ACP thioesterase gene AtFatA was amplified by PCR from cDNA of arabidopsis and double digested by EcoR I/Xba I, then linked to the plasmid digested with same enzymes to get the recombinant plasmid pPICZaA-AtFatA. We transformed the gene into Pichia pastoris GS115 by electroporation and screened positive colonies by YPD medium with Zeocin. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) results showed that the recombinant enzyme had a molecular of 45 kDa band which was consistent with the predicted molecular mass and we constructed the expression system of gene AtFatA in fungus for the first time. Under shake-flask conditions, Gas Chromatograph-Mass Spectrometer-computer results indicated that recombinant strain produced 51% more extracellular free MCFAs than the wild and its yield reached 28.7% of all extracellular fatty acids. This figure is 10% higher than the control group. The result provides a new way to produce MCFAs.

This study aims to develop a method to detect bovine multi-cytokines based on flow cytometry. Previously we have prepared and screened monoclonal antibodies against bovine cytokines IFN-γ, IL-2, TNF-α, IP-10 and MCP-1. These bovine cytokine monoclonal antibodies were fluorescently labeled, and the combination of antibody and cell surface molecules were used to develop the method for detecting bovine multi-cytokines. Subsequently, the developed method was used to determine the cytokine expression profile of Mycobacterium bovis BCG infected bovine peripheral blood mononuclear cells in vitro, and evaluate the cytokine expression level of peripheral blood CD4⁺ T cells of tuberculosis-positive cattle. The bovine multi-cytokine flow cytometry detection method can effectively determine the cytokine expression of BCG-infected bovine peripheral blood T lymphocytes. Among them, the expression levels of IFN-γ, IL-2, and TNF-α continue to increase after 40 hours of infection, while the expression levels of IP-10 and MCP-1 decreased. The combined detection of IFN-γ, IL-2, and TNF-α on CD4⁺ T lymphocytes in peripheral blood of cattle can effectively distinguish tuberculosis-positive and tuberculosis-negative samples. This method may facilitate evaluating the level of cellular immune response after bovine pathogen infection and vaccine injection.
