Background and Purpose:Recent studies have shown that survivin is an anti-apoptosis gene,which is involved in carcinogenesis and drug resistance of leukemia.Antisense oligodeoxynucleotide(ASODN) can be used to inhibit the expression of survivin,inducing apoptosis and enhancing the chemosensitivity of leukemic cells.This study was designed to explore the effect of survivin ASODN on the growth,apoptosis,and caspase-3 activity of leukemia cell line K562/A02 with the phenotype of drug resistance.Methods:Survivin ASOND was transfected to K562/A02 cells by liposomal reagent,The rate of inhibition,expression of survivin mRNA,apoptosis,and activity of Caspase-3 were detected by colormetric MTT,RT-PCR,flow cytometry and fluorometer,respectively.Results:Survivin ASODN could inhibite the cell proliferation in a dose and time dependent manner.Compared with controls,expression of survivin mRNA decreased by 36.2%(P

Objective To investigate the effects of morphine on PTEN expression and NF-κB activity in human gastric carcinoma cell line MGC-803.Methods The human gastric cancer cell line MGC-803 was purchased from Cell Biology Research Institute,Chinese Academy of Sciences,and cultured in DMEM liquid culture medium.The cells were randomly divided into 2 groups(n = 6 each): control group and morphine group.The cells was exposed to 0.1 μmol/L morphine in morphine group.The apoptosis was assessed by flow cytometry after being incubated with morphine for 24 h.PTEN expression and NF-κB activity were detected using RT-PCR and Western blot.Results The apoptotic rate was significantly increased,PTEN expression was up-regulated and NF-κB activity was significantly decreased in morphine group compared with control group(P < 0.05).Conclusion Morphine can promote the apoptosis in human gastric cancer cells by up-regulating PTEN expression and decreasing NF-κB activity.

Objective In order to improve the teaching effectiveness of anatomy in nursing, this article made an exploration on the experimental teaching reform combined with the characteristics of nursing profession. Methods The nursing students of class 1and 2 of 2013were set as the research object. The class 1 (110) as experimental class, class 2 (110) for the control group. In the experimental class, the reform of teaching method and teaching quality was improved by adjusting the teaching syl-labus and teaching contents. The control class used the traditional experimental teaching method. The experiment class' teaching reform research of the human anatomy carried on the 1 semester. Exam achievement evaluation and the questionnaire survey were adopted to assess the teaching effect. SPSS 13.0 software was used to do statistical analysis and t test was used to compare two groups of students test scores, experiment grades, test scores and total scores. Results Experimental theory examination results [(47.80±7.30) vs. (44.85±8.38)], experiment grades [(15.48±1.76) vs. (14.55±2.19)], ex-periment test scores [(15.52±2.22) vs. (14.35±2.64)], total score [(78.80±8.99) vs. (73.75±10.53)] were better than control group (P<0.05). In questionnaire survey,more than 80% of the students think that the reformed teaching method can help to improve the teaching effect. Conclusion In human anatomy experiment teaching reform, the reformed experiment teaching method can significantly improve students' scores and the teaching effect. It is better than the traditional method, and is worth publicizing.

Objective To report the diagnosis and treatment of an imported case of schistosomiasis haematobium,including the pathological features of the disease and therapeutic efficacy of praziquantel. Methods The data of the patient with schistoso?miasis haematobium were collected,and the pathological features of the bladder tissue were observed under a microscope. More?over,the patient was treated with praziquantel,and his urine was collected before and after the treatment. The eggs in the urine were examined by a microscope after sediment and the miracidia were hatched. Results The patient once worked in Angola for three months,and after returning home he had the symptoms of intermittent painless terminal hematuresis. It was ineffective af?ter anti?inflammatory treatment in a number of hospitals. There were no sand spots discovered under the cystoscope. However , the inflammatory reaction to parasite with a lot of eosinophils infiltration in the bladder mucosa was found on the pathological sec?tions under a microscope,and the egg structure was observed with individual characteristics. The eggs were detected in the urine and the miracidia were hatched before the praziquantel treatment. The hematuria symptoms disappeared after the praziquantel treatment. The eggs were still detected in the urine 7 days post?treatment,but the miracidium could not be hatched. One month and 6 months post?treatment,the eggs were not detected in the urine. Conclusions The imported cases of schistosomiasis hae?matobium are often misdiagnosed,and therefore,it is necessary to strength the health education to the workers overseas and also to improve the ability of diagnosis in medical staff. For the case reported in this paper,there are typical structure of Schistosoma haematobium eggs and egg?granulomas on the pathological sections of bladder tissues. Praziquantel has satisfactory treatment re?sults.

OBJECTIVE:To provide reference for further formulation of the rational use of vancomycin. METHODS:Retro-spective analysis was conducted on the related information of discharged patients who intravenously used vancomycin from Jun. 2013 to Dec. 2014. RESULTS:178 patients were enrolled,with average age of 59.6 and 73.60% male,who were mainly with lung infectious(74.72%). Support examinations were sufficient before using of vancomycin. 66.29% patients were empirically giv-en vancomycin with pathogenic detection rate of 85.39%. 71.91% patients were conducted therapeutic drug monitoring with only 47.54% of first blood samples achieved the target range. CONCLUSIONS:Vancomycin application is generally rational in our hos-pital. However,issues like duration of empirical therapy,rational therapeutic monitoring,and individualized start dosing still need to be noticed.

Objective To investigate the clinical application of acupuncture combined with general anesthe -sia in gynecologic laparoscopic surgery .Methods 60 ASA( the American society of anesthesiologists )Ⅰ-Ⅱpatients undergoing elective gynecologic laparoscopic surgery were randomly divided into the acupuncture group and control group.Patients in the acupuncture group were chosen Hegu (LI 4),Neiguan(PC 6) on both sides.After acupuncture, the two acupoints,electroacupuncture stimulated 20-30min,then administered general anesthesia ,electroacupuncture until surgery finished ,the control group received general anesthesia only .The drug dosages of the two groups was regu-lated,maintained anesthesia depth bispectral index ( BIS) between 40 and 60.The changes of the blood pressure ( BP) ,heart rate and BIS of the two groups at the same time points were observed;the propofol and remifentanil dos-age after the surgery ,the awaken time and extubation time ,OAA/S score and pain score after wake ,the happening of restlessness,chills,nausea and vomiting ,the usage of narcotic analgesics postoperation ,and the intraoperative aware-ness were recorded .The effect of acupuncture combined with general anesthesia was evaluated .Results Anesthetic dosage propofol of the acupuncture group [(7.44 ±1.30)μg· kg-1· h-1] was less than [(8.66 ±1.24)μg· kg-1· h-1] of the control group (t=3.720,P=0.001),remifentanil dosage was also less than the control group [acupunc-ture group (10.59 ±2.58)μg· kg-1· h-1,control group (11.93 ±2.27)μg· kg-1· h-1,t=2.168,P=0.034]. Compared with the basic value ,the BP values were higher at the time of intraoperation ,waking,extubation and 10 min after extubation (all P<0.05),the acupuncture group had more stable BP .Compared with the acupuncture group , heart rates in the control group were faster at extubation and 10min after extubation .Recovery time and extubation time of the acupuncture group were (9.05 ±2.36)min and (1.61 ±2.40)min,which were shorter than (12.50 ± 3.20)min and (15.90 ±3.37)min of the control group (P<0.05).Pain score(VAS) in the acupuncture group was lower than that of the control group .Consciousness score was higher in the acupuncture group ,the incidence rates of restlessness,chills were less.Conclusion The use of acupuncture combined with general anesthesia in gynecologic laparoscopic surgery can reduce the dosage of general anesthetics ,shorten the awaken time and extubation time ,increase the OAA/S score of the patients ,relieve pain ,and the recovery quality is higher .
