Malnutrition is the common complication for the patients with gastrointestinal neoplasms during perioperative period.Tumor and chemotherapy drugs are the main influencing factors of patients with malnutrition.The correct evaluation of the nutritional status in patients is the basis of individualized nutrition therapy.New evaluation methods and nutritional preparations could more help patients with gastrointestinal neoplasms during perioperative period to maintaining good nutritional status.

Objective The study analyzes the inadequacies of the research integrity educational practice for the medical postgraduate students in the present stage of China.Furthermore,the paper puts forward improvement suggestions and clears the direction for further efforts.Methods From the perspective of the educational law about cognition,emotion,will and behavior,the comparative analysis method is used,based on the rich experience in the United States.Results There are inadequacies of the research integrity educational practice for the medical postgraduate students in China,including that students lack knowledge learning motivation,and the pattern of education is simple.There are not enough emotional experience channels and the participation of students.Students lack honesty will training,and the intensity of supervision and punishment is not strong.The honesty recognition mechanism is weak,and cannot be used to guide practice.Conclusions In order to improve the level of the research integrity for the medical postgraduate students in China,we should optimize the system,follow the law of education,strengthen the transmission of knowledge,put the academic honesty education into normal work,enhance the emotional experience,build a participatory mechanism,highlight the positive guide,and increase the intensity of punishment.

Objective To investigate the value of Kugel patch for elderly patients with recurrent inguinal hernia.Methods From February 2004 to February 2007,37 elderly patients with recurrent inguinal hernia received surgical treatment in our hospital.The patients were divided into two groups according to the surgical methods.Twenty-one patients,including 17 cases of unilateral indirect inguinal hernia,1 bilateral indirect hernia,1 direct hernia,1 indirect hernia complicated with femoral hernia,and 1 indirect hernia complicated with direct hernia,received hernia repair with Kugel patch via the posterior approach.The other 16 patients,including 15 cases of unilateral indirect hernia and 1 case of direct hernia,were treated with TAPP.Results The operation time in the Kugel group was significantly shorter than that in the TAPP group [(23.2?5.8) min vs(40.5?5.2) min,t=-9.392,P=0.000].In the TAPP group,2 patients complained of surgical-site pain or tension,while no patient in the Kugel group had the symptoms(?2=0.869,P=0.351).The mean hospital stay in the Kugel group was shorter than that in the TAPP group [(5.7?0.7)d vs(6.3?0.8) d;t=-2.429,P=0.020].The patients were followed up for 3-36 months,none of them had recurrence.Conclusions As an new,non-tension,safe,and minimally invasive method,hernia repair using Kugel patch through the posterior approach is of great advantage to elderly patients.The method is worth being used widely.

OBJECTIVE:To observe therapeutic efficacies and safety of diltiazem combined with ciclosporine in the treatment of nephrotic syndrome complicated with acute renal injury. METHODS:A total of 66 patients with nephrotic syndrome and cute kid-ney injury were randomly divided into control group(30 cases)and observation group(36 cases). Control group was given routine treatment;observation group was additionally given Diltiazem hydrochloride tablet 5 mg orally,twice a day,and Ciclosporin soft capsules 1.5 mg/(kg·d)orally,twice a day. Treatment course of 2 groups lasted for 20 d. Clinical efficacies of 2 groups were ob-served. The serum creatinine and kidney injury molecule 1(KIM-1),24 h urine volume,24 h urine protein levels,AKI classifica-tion,follow-up and recurrence were observed before and after treatment as well as the occurrence of ADR. RESULTS:The remis-sion rate of observation group was significantly higher than that of control group,and recurrence rate was significantly lower than control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the serum creatinine levels,KIM-1,24 h urine pratein,24 h urine and AKI classification between 2 groups (P>0.05). After 2 weeks and 1 month of treatment of observatiom groups,and after 1 month of treatment of control group,serum creatinine levels,KIM-1 and 24 h urine protein of observation group were significantly lower than before treatment,and the observation group was significantly lower than the control group;24 h urine and the ratio of gradeⅠby AKI classification were significantly more than before treatment,and the observation group was significantly more than the control group,with statistical significance(P<0.05). Follow-up rate in 2 groups were 100%,and there was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on routine treatment,diltiazem combined with ciclosporin shows significant therapeutic efficacy in the treatment of nephrotic syn-drome and acute renal injury with good safety.

Only in recent years, attentions have been drawn to the significance of expressing killer cell inhibitory receptors (KIR) in T cells KIRs specifically bind to the corresponding region of the MHC class I molecules and transmit negative signals to prevent cytotoxity of T cells. When the ligands of KIRs are missing, the lysis of the target cells can't be avoided. Perhaps the existence of KIRs is the main mechanism for preventing T cells from attacking autologous tissues. The recognition mechanism of the interaction between the KIR + donor T cells and the recipient's MHC class I molecule expressing tissue cells might shed light on the establishment of the immunotolerance for the prevention of allo-graft rejection and graft-versus-host disease.

[Objective]To investigate the expression of Survivin and its relationship with expression of PTEN and cyclinD1.[Method]Immonohistochemical method(SP method)was used to detect the expression of Survivin,PTEN and cyclinDl in 40 osteosarcoma tissues and 20 ostanchondroma tissues.[Result]The expression rate of Survivin was significantly higher in osteosarcoma(62.5%)than that in osteochondroma(10.0%)(P

Buthionine salfoximine (BSO) is a chemotherapeutic sensitizor under clinical trial. BSO can reverse multidrug resistance in vitro and in vivo. The author reviewed the mechanism, pharmacodynamics, pharmacokinetics and the progress in clinical research of BSO. BSO is a selective inhibitor of 7-glutamylcysteine synthetase, the rate-limiting enzyme in gluthionine synthesis. Depletion of intracellular gluthionine by BSO can reverse tumor resistance to chemotherapeutic a-gents such as platinating and alkylating agents. In tumor-bearing animals BSO enhanced the therapeutic index of chemotherapeutic agents. Animals treated with BSO had a longer life span. Pharmacokinetics of BSO was a two-compartment manner in mice, dogs and huamn beings. The efficacy of BSO in cancer patients is being investigated in clinical trial.

Objective To explore the main affecting factors on sanitary quality of public places and to assess the sanitary quality scientifically. Methods The sanitary qualities of 6 kinds of public places of entertainment in Taiyuan during 1998～2000 were assessed using the method of compreheusive fuzzy assessmeat. Results All of 6 kinds of public places revealed similar sanitary qualities. All of the sanitary indexes accorded with the related National Sanitary Standards. The sanitary qualities were better for ballrooms, theaters, bar and billiard rooms in hotels with Grade Ⅰ quality, and were worse for tennis and bowling halls with Grade Ⅱ quality. The assessments on single index showed that the affecting factors of sanitary quality of public places of entertainment were the levels of CO2, noise and CO. Conclusion The sanitary quality of entertainment public places was better during 1998～2000.

OBJECTIVE:To establish an HPLC method for the determination of gastrodin in Choudongning capsule. METHODS:The sample was determined on Elite C18 column(250 mm?4.6 mm,5 ?m);the mobile phase consisted of methanol -water(3∶97) at a flow rate of 1.0 mL?min-1;the detection wavelength was set at 221 nm. RESULTS:The linear range of gastrodin was from 0.051 ?g to 0.357 ?g(r=0.999 9) and its average recovery was 98.99%(RSD=1.91%,n=6).CONCL-USION:The method is convenient,accurate and reproducible,and it is applicable for the quality control of Choudongning capsule.
