Objective To investigate the curative effect of Candesartan on chronic systolic heart failure in Tibetan pla?teau. Methods A total of 526 patients with chronic systolic heart failure were divided into two groups randomly (Treatment group N=252;Control group N=274). Regular medicines, such as cardiac, diuretic and vasodilator drugs , are given to pa?tients in both groups according to their primary underlined diseases. Additionally, enalapril is added in control group, while candesartan is added in treatment group. Improvement of cardiac function, LVEF, LVEDD and blood pressure were compared between these two groups after 8 weeks. Results There was no significant difference in effective rate (i.e., 45.2%in treat?ment group and 44.9% in control group, respectively), efficiency rate (i.e. 54.8% in treatment group and 55.1% in control group, respectively) and inefficiency rate (i.e. 2.0%in treatment group and 2.2%in control group, respectively) between treat?ment and control groups . After treatment, LVEF in the two groups are all improved, while LVEDD and blood pressure both de?creased with statistical significance. However, the difference between the two groups is not significant. Conclusion No sta?tistical difference was found in curative effect on chronic systolic heart failure in Tibetan Plateau between two groups.

BACKGROUND: Clinically, in patients undergoing hematopoietic stem cell transplantation (HSCT), human cytomegalovirus (HCMV) can be associated with delayed platelet engraftment, phenotypically abnormal peripheral blood leukocytes, and graft rejection, possibly through a direct viral effect on hematopoietic progenitor cells after HCMV infection. OBJECTIVE: To investigate the inhibitory effect of ganciclovir (GCV) on proliferation of colony forming unit (CFU) granulocyte-macrophage (CFU-GM), CFU-erythroid (CFU-E), CFU T-lymphocyte (CFU-TL), CFU-multipotential (CFU-Mix) and CFU-megakaryocyte (CFU-Mk) progenitor cells of cord blood (CB) and the protective effects on them. DESIGN: Contrast observational study.SETTING: Department of Molecular Biology, Affiliated Hospital of Luzhou Medical College.PARTICIPANTS: A total of 20 cord blood (CB) samples (with 10 mL for each sample) from fetal umbilical vein of normal term spontaneous delivery neonates were provided by the Department of Gynaecology and Obstetrics, Affiliated Hospital of Luzhou Medical College. All the patients were informed and agreed with the experiment.METHODS: The experiment was carried out in the Department of Molecular Biology, Affiliated Hospital of Luzhou Medical College from June 2004 to December 2006. Colony forming unit-assay was applied to observe the suppression effect of HCMV-AD169 strain on CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk of CB with the presence of GCV. The techniques of polymerase chain reaction (PCR) and fluorescence quantification PCR were used to demonstrate the existence of HCMV-AD169 DNA in the colony cells of cultured CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk. Normal progenitor cells culture system was regarded as blank control group; normal progenitor cells culture system with inactivated HCMV fluid as inactivated (IV) control group.MAIN OUTCOME MEASURES: ① The number and maintaining duration of colonies of cultured progenitor cells were counted by using a light inverted phase contrast microscope. ② The techniques of PCR and fluorescence quantification PCR were used to demonstrate the existence of HCMV-AD169 DNA in the colony cells of cultured progenitor cells.RESULTS: ① Number and lasting time of colonies: The numbers of CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk colonies in the HCMV infection group were significantly less than those in the blank control group (P < 0.01). The maintaining duration of colonies in the HCMV infection group was significantly shorter than that in the blank control group (P < 0.01). HCMV-DNA copies of colony cells of GCV group decreased significantly by using fluorescence quantification PCR compared with HCMV group (P < 0.01), while negative in blank control and inactivated control in CFU-MK and CFU-Mix. ② CFU Growth rate: The Growth rate of colonies was 37.4%, 74.2%, 40.1%, 67.4% and 38.9% of CFU-GM, CFU-E, CFU-TL, CFU-Mix and FU-MK, respectively. ③ CFU-HCMV-AD169 DNA: Fluorescence quantification PCR showed that nucleonic acid content of progenitor cells after GCV-affected HCMV infection was decreased as compared with that after HCMV infection (P < 0.01).CONCLUSION: The differentiation and proliferation of CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk are significantly inhibited after infected with CMV-AD169 strain. The growth of hematopoietic progenitor cell after HCMV-AD169 infection is promoted by GCV, which suggests that GCV has an effect of anti-HCMV in vitro.

Objective To observe the effects of Sishen Pills on gene and protein expressions of toll-like receptor 2 (TLR-2) and toll-like receptor 4 (TLR-4) of colonic tissue in spleen-kidney yang deficiency rats with ulcerative colitis (UC); To discuss its mechanism of action for spleen-kidney yang deficiency UC. Methods Lavage of senna +intraperitoneal injection of hydrocortisone injection + enema of 2,4,6-trinitrobenzene sulfonic acid/ethanol were used to establish the model of UC of spleen-kidney yang deficiency type. 90 Wister rats were randomly divided into blank group, model group, Salazosulfadimidine group and the Sishen Pills high-, medium- and low-group. Each medication group was intervened by relevant medicine. RT-qPCR was used to detect the expressions of TLR-2 and TLR-4, and Western blot was used to detect the protein expressions of TLR-2 and TLR-4. SOD and MDA in serum were detected. Results Compared with the blank group, SOD activity decreased and MDA content increased in the model group (P<0.01); gene and protein expressions of TLR-2 and TLR-4 increased significantly (P<0.05). Compared with model group, SOD increased and MDA content decreased in all the medication groups (P<0.05, P<0.01); gene and protein expressions of TLR-2 and TLR-4 decreased (P<0.05, P<0.01). Conclusion Sishen Pills can achieve the treatment of UC by improving the metabolism of oxygen radicals in colonic tissue and regulating the immune system of the intestinal epithelium.

Objective To investigate the relationship between the resting heart rate (RHR) and target organ damage (TOD) in elderly patients with metabolic syndrome(MS). Methods 264 elderly patients with MS were divided into four groups according to the level of RHR: RHR1 group, RHR<65 beats/minute (bpm) (46 cases) ;RHR2 group, 65≤RHR<75 bpm (77 cases);RHR3 group, 75 bpm≤RHR<85 bpm (89 cases);RHR4 group, RHR≥85 bpm (52 cases).Electrocardiography, echocardiography, carotid uhrasonography, crcatinine clearance rate (Ccr) and quantitative assay of 24 hours' albuminuria were performed. Results (1) Compared with RHR1, RHR2 and RHR3 groups, RHR4 group showed higher levels of carotid intima-medial thickness (IMT), carotid arterial diameter (CAD), left ventricular mass index (LVMI) and albuminuria(P< 0.05 or P<0.01), and lower levels of left ventricular ejection fraction (LVEF) and Ccr (all P< 0.01). (2) The IMT, CAD, LVMI and albuminuria were positively correlated with RHR (r=0.33, 0.23, 0.61, 0.58, respectively, all P<0.01). However, the LVEF and Ccr were negatively correlated with RHR (r=-0.59, -0.51, all P<0.01). (3) Logistic multivariate analysis showed that RHR and pulse pressure (PP) had effects on myocardial hypertrophy, coronary heart disease, heart failure, cerebral stroke and renal dysfunction(P<0.05 or P<0.01). Except heart failure, PP played a more important role than RHR. Coneinsions RHR may be an independent risk factors for TOD in elderly patients with MS,and RHR regulation is important for the development of MS in the elderly.

Cytochrome P450 oxidoreductase (POR) is the only electron donor for all microsome Cytochrome P450 monooxygenases which are phase I metabolizing enzymes responsible for the metabolism of more than 80% drugs used in clinic.Also,POR metabolizes some anti-tumor prodrugs directly.Therefore,the alteration in POR activity caused by the polymorphisms of POR gene will be of great clinical significance.This review summarizes the newest advancement on the effects of POR polymorphisms on drug metabolism.
