Diabetic cardiomyopathy ( DC) is an independent complication of diabetes mellitus accompanied with cardiac metabolic imbalances ( increase of fatty acids and reduction of glucose) ,which would impair cardiac function and structure seriously. Peroxisome proliferator-activated receptors ( PPARs) are ligand-activated transcription factors belonging to the nuclear hormone receptor superfamily,and they could transcriptionally regulate energy metabolism and function. PPARs also play an important role in regulating metabolism in DC heart,and directly or indirectly affect cardiac function and structure.

Medical Journal of Chinese People's Liberation Army 1981;0(04):-
Objective To investigate the karyotype of Candida albicans DNA by pulsed field gel electrophoresis (PFGE), and evaluate the significance of the karyotype used as a method for molecular epidemiology controlling. Methods 14 isolates of C. albicans from various clinical samples were evaluated for molecular relatedness by PFGE. Isolates were identified by MircroScanWalkAway 96 RY-ID. Results The karyotype analysis revealed a total of 9 different genotypes among 14 isolates of C. albicans from 11 patients. Among the isolates, 4 were isolated from difference parts of a patient and had same karyotype, implying that they were from the same isolate and differed to different sub-clones. In another 10 isolates from different patients, 3 had same karyotype, and the karyotypes of the remainder 7 isolates were different. Conclusion PFGE may well reveal the autoploidy and polymorphism of the isolates of C. albicans with different origin, thus may be used as an effective method for molecular epidemiological study.

This study was aimed to compare and investigate protective effects of metformin and rosiglitazone on cardiac dysfunction in experimental diabetic cardiomyopathy (DC) model rats. The experimental DC rat model was induced by feeding high calorie diet plus single intraperitoneal injection of small dosage of streptozotocin (STZ). Then, intragastric administration of metformin (140 mg·kg-1) or rosiglitazone(2 mg·kg-1) was given to DC rats for consecutive 6 weeks. Parameters of general signs, eating amount, blood sugar, blood lipids, heart function, heart structure and lipometabolism of myocardial tissues were measured. The results showed that both metformin and rosiglitazone can obviously improve the myocardial injury of DC model rats and reduce the CK value (P < 0.01). Metformin can obviously increase the cardiac output of DC model rats (P < 0.01). Rosiglitazone can improve the maximum rate of myocardial contraction and diastole of the model rat's left ventricle (P < 0.05). Both metformin and rosiglitazone can decrease interventricular septal thickness (IST) value (P < 0.01). Metformin can obviously im-prove general signs of DC rats, inhibit body weight loss and reduce water intake (P < 0.05). Metformin can obvi-ously reduce the blood sugar level (FBG, GSP, HbA1c and FMN) of DC rats (P < 0.05, or P < 0.01) as well as the concentration of TG (P < 0.01). Rosiglitazone can reduce the concentration of FBG and HbA1c (P < 0.05). Meanwhile, rosiglitazone can significantly reduce the concentration of TG and LDL as well as obviously increase the myocardial FA-β-oxidase (P < 0.05). It was concluded that both metformin and rosiglitazone can recover the cardiac dysfunction and myocardial injury of DC rats on certain level. Metformin showed more effects on eating amount and body weight improvements of DC rats.

[Abstratc] Objective The function of cIAP1 in the progression of ovarian cancer has not been clarified . This study is to explore the involvement of cIAP 1 in regulating biological behaviors of ovarian cancer cells by u-sing RNA interference(RNAi)technology.Mte hods The short hairpin RNA plasmid targeting cIAP1 was con-structed and transfected into Skov 3 cells.The levels of cIAP1 mRNA and protein were investigated by RT -PCR and Western Blot respectively .MTT assay and flow cytometry were used to evaluate cell proliferation and apopto-sis.R esults The rate of cIAP1 transfection was 74.7%performed by flow cytometric analysis .cIAP1 expression was significantly down -regulated at both mRNA and protein levels ,which resulted in a decrease of cell prolifera-tion and invasion capability in vitro .Conclusion This study implies that cIAP 1 might play an important role in the progression of ovarian cancer ,and it could be a potential target for therapeutic anti -cancer drugs .

ObjectiveTo investigate the role of caspase 3 in HMME-induced apoptosis in hypertrophic scar fibroblasts (HSFs).MethodsFibroblasts were obtained from 10 patients with untreated hypertrophic scar,and subjected to a primary culture.After 4 to 6 passages of culture,the HSFs were divided into 3 groups to remain untreated(control group),be treated with HMME followed by photodynamic therapy (HMME-PDT group),or the combination of HMME and Z-DEVD-FMK followed by photodynamic therapy (caspase 3 inhibitor group).At 12 hours after the therapy,HSFs were collected and immunofluorescence microscopy was used to observe the fluorescence intensity of caspase 3 after staining with fluorescein isocyanate (FITC) and popodium iodide (PI),flow cytometry was performed to determine the percentage of caspase 3-positive HSFs and apoptosis rate in HSFs after single staining with FITC and PI respectively.Results The fluorescence intensity of caspase 3 was weak in the control group and caspase 3 inhibitor group,but was strong in the HMME-PDT group.An increased percentage of caspase 3-positive HSFs was noted in the HMMEPDT group compared with the control group and caspase 3 inhibitor group(30.86% ± 1.21% vs.3.12% ±0.28% and 2.46% ± 0.18%,t =19.92,21.76,both P < 0.05).The apoptosis rate in HSFs was significantly higher in the HMME-PDT group and caspase 3 inhibitor group than in the control group(30.54% ± 3.78% and 10.46% ± 2.15% vs.2.45% ± 0.22%,t =35.90,27.97,both P< 0.05),and higher in the HMME-PDT group than in the caspase 3 inhibitor group.ConclusionsThe apoptosis in HSFs induced by HMME-PDT is closely related to the activation of caspase 3,while caspase 3 seems to be dispensable for the apoptosis.
