AIM: To compare the effects of histidine-tryptophan-ketoglurate(HTK)solution, University of Wisconsin(UW)solution and St.Thomas(ST) Cardioplegia solution Ⅱ on hypothermic preservation of isolated rat hearts. METHODS: Isolated hearts from male Wistar rats were mounted on a Longendorff apparatus to estimate left ventricular end-diastolic pressure(LVEDP),left ventricular developed pressure(LVDP), rate of change of left ventricular pressure(d p /d t max ,d p /d t min ) and coronary flow(CF).Twenty-four rats were randomly divided into three groups: HTK group, UW groups and ST group.They were arrest and stored at 4℃ in each preservation solution for 6 hours. Following storage, they were reperfused and postpreservative function was measured to assess cardiac functional recovery. Frozen samples were analyzed for concentration of adenosine triphosphate. RESULTS: The concentration of adenosine triphosphate in three groups was significantly different( P

Objective To investigate the effect of atorvastatin on the curative effect and cardiovascular events in patients with unstable angina pectoris.Methods128 patients with UAP were enrolled in Jinhua Central Hospital from August 2014 to August 2016, and 128 patients with UAP were randomly divided into observation group and control group.All the patients were given low salt and low fat diet.Two groups of patients were anti-platelet aggregation, blood pressure, lipid-lowering and other conventional treatment, observation group on the basis of simultaneous atorvastatin calcium 40mg/d, oral, once every month.The levels of TC, TG and LDL-C, HDL-C and the incidence of cardiovascular events were compared between the two groups before and after treatment.ResultsThere was no case of cardiac death in the observation group and the control group.The incidence of cardiovascular events in the observation group was 9.38%, which was significantly different from that in the control group (P<0.05).The levels of TC, TC and LDL-C in the observation group were significantly higher than those before treatment and control group, respectively.The clinical effect of the observation group was significantly better than that of the control group, the difference was significant (P<0.05).ConclusionAtorvastatin can significantly improve the efficacy of unstable angina treatment, and reduce blood lipid levels, reducing the incidence of cardiovascular events, improve the prognosis.

Objective To investigate the relationship between the expression of Fas or FasL and the apoptosis of peripheral blood T and B lymphocytes in systemic lupus erythematosus (SLE) patients. Methods The expression rates of Fas and FasL and apoptosis rates of peripheral blood T and B lymphocytes were detected by flow cytometry (FCM) in 30 active SLE patients and 30 inactive SLE patients and 30 healthy controls. Results There were significant difference in the expression rates of Fas of T and B lymphocytes among three groups (P0.05). In addition, the activity of SLE had no correlation with the expression rates of Fas or FasL on T or B lymphocytes but has positive correlation with the apoptosis rates of T or B lymphocytes. And no correlation was found between the expression rate of Fas or FasL and the apoptosis rate of neither T nor B lymphocytes. Conclusion The apoptosis of peripheral blood lymphocytes is influenced by many factors in SLE patients, but is abnormally increased at last, especially in active SLE. It is inferred that the increase of apoptosis rate of peripheral blood lymphocytes plays an important role in the pathogenesis of SLE.

Objective To investigate the safety and superiority of fast track surgery (FTS)in elderly patients during the perioperative peri-od of laparoscopic cholecystectomy (LC).Methods The clinical data of 124 elderly patients who underwent LC at the Department of Gen-eral Surgery in our institution between January 2010 and March 2014 were assessed,with 62 cases assigned to FTS group and 62 cases to conventional method group.Anal exhaust time,feeding time,off-bed activity time,and length of hospital stay were compared between the two groups,and postoperative results and adverse reactions were recorded.Continuous data were analyzed using the independent-samples t test,and categorical data were compared using the chi-square test.Results Compared with the control method group,patients in the FTS group showed earlier postoperative anal exhaust,feeding,and off-bed activity,a shorter length of hospital stay,and a lower incidence of postoperative cardiovascular and cerebrovascular complications (P<0.05).Conclusion FTS is an effective approach to accelerate rehabil-itation in elderly patients after LC.

Objective To evaluate the effect of interactive case teaching(ICT) method in teaching hematology.Methods Sixty students were randomly selected from 2009 grade clinical medicine majors in the Third Military Medical University and were divided into experimental group and control group,each group with 30 students.Students in experimental group used ICT； while those in control group used traditional teaching method.Closed book exam was conducted for students in experimental group and control group at the end of the semester； question types of the exam included concept questions (nouns explain,choice,short answer questions) for 70 points,cases analysis question for 30 points,a total of 100 points.Data were expressed as mean ± standard deviation ((x) ±s) and analyzed with SPSS 20.0 independent sample t test.Questionnaire was designed and feedback from students was statistically analyzed.Results There was no statistical differences between experimental group and control group in concept questions (P =0.580),however,in terms of cases analysis question,scores in experimental group were significantly higher than those in control group (P =0.000) ； total scores of experimental group were also significantly higher than those in control group (P =0.016).Feedback showed that the students highly valued the form and effect of ICT.Conclusions Using ICT in teaching hematology can arouse students' enthusiasm for study,cultivate their independent thinking and ability of problem-solving.Meanwhile,ICT can combined theoretical teaching with clinical practice well and improve the quality of teaching.

ObjectiveTo investigate the inhibitory effects and related toxicity of all-trans-retinoic acid(ATRA) combined with arsenic trioxide(As2O3) on transplanted human bladder neoplasms in nude mice.MethodsThe subcutaneously transplanted tumor models of human bladder neoplasms in nude mice were established and then it was randomly divided into four teams: Saline group, ATRA group, As2 O3 group and the combination of ATRA and As2 O3 group.Each group composed of 10 nude mice and received intratumor injection in the following 14 d.The tumor growth inhibitory rate was calculated.The pathological changes of tumor,cardiac, liver, and kidney were observed after H.E.staining.The expression of MVD (Marked with CD43) and VEGF were detected by SP of immunohistochemistry.Blood routine examination and hepatic and nephritic functional examination was carried out to evaluate the side-effects.Results The tumor growth was significantly suppressed in ATRA group(inhibitory rate was 41.82％) and As2O3 group (inhibitory rate was 43.77％) compared with saline group.When ATRA combined with As2O3 ,inhibitory effects were improved(inhibitory rate was 68.55％).The difference of growth inhibitory rate between each group was obviously significant(x2 =26.81, P ＜0.01).There was less expression of MVD (Marked with CD43) and VEGF in ATRA group and As2 O3 group and the combination group compared with saline group (ODVEGF = 19.23 + 2.32,20.72 + 2.01,17.16 ± 1.59,27.33 ± 2.17, respectively; ODMVD = 44.77 + 8.25,43.39 + 7.41, 30.56 + 7.71,141.12 + 8.38, respectively), and the suppressed effect in the combination group was most significant (t = 3.16,3.08,3.37, P ＜ 0.01).WBC inhibition was seen in ATRA group and As2O3 group and the combination group, but no significantly difference among them(P ＞0.05).Hepatic and nephritic toxicity were not found.ConclusionsCombination of ATRA and .As2O3 had obvious synergistic effects on transplantéd tumor of human bladder neoplasm in nude mice, and moderate white blood cell inhibition and no hepatic or nephritic toxicity.

AIM: We tested the hypothesis that marrow s tr omal cells (MSCs), when implanted into self-myocardium, can undergo milieu-depen dent differentiation, express cardiomyogenic phenotypes and enhance angiogenesis and cardiac function of ischemic hearts in vivo. METHODS: In order to achieve a safe and persistent effect, we ex plored the potential of autologous MSCs transplantation. One week after myo cardial infarction induced by occlusion of left anterior descending artery, auto logous MSCs labeled with BrdU (bromodeoxyuridine) in vitro was administered intramyocardially into the infarct area of the same donor rabbits. RESULTS: By 1 months, transplanted MSCs demonstrated to be myoge nic differentiation with the expression of ?-sarcomeric actin (5C5). MSCs impla ntation significantly increased vascular density in the infarct zone and resulte d in markedly improved the left ventricular contractility. CONCLUSION: The finding indicates that autologous MSCs transplan tation may represent a promising therapeutic strategy with free of ethical conce rns and immune rejection.
