ABSTRACT
OBJECTIVE: To evaluate the effect of pitavastatin on blood glucose in patients with hypercholesterolemia, and to investigate the efficacy of pitavastatin in diabetic patients combined with hypercholesterolemia. METHOD: This study was a 12-week, multi-center, open-label, without parallel-group comparison, phase IV clinical trail. RESULTS: Contrasting to baseline, the prevalences at week 4 and 12 post-treatment of abnormal fasting plasma glucose (FPG) and glycosylated hemoglobin A1c (HbA1c) (FPG: 14.2%vs 14.1% and 11.0%; HbA1c: 14.3% vs 15.1% and 16.1%) in the safety set subjects without diabetes mellitus (DM), as well as in those with DM but not taking glucose-lowering drugs (FPG: 7/7 vs 4/7 and 5/7; HbA1c: 5/5 vs 4/4 and 5/5) had no significant changes (all P values > 0.05). Contrasting to baseline, the levels of TC [(6.51 ± 0.94) mmol/L vs (5.12 ± 0.93) mmol/L and (4.54 ± 1.00) mmol/L], LDL-C [(4.11 ± 0.79) mmol/L vs (3.02 ± 0.81) mmol/L and (2.51 ± 0.70) mmol/L] and TG [2.10 (1.53, 2.54) mmol/L vs 1.62 (1.26, 2.00) mmol/L and 1.35 (1.10, 1.86) mmol/L]at week 4 and 12 post-treatment in the per protocol set 55 subjects with DM were significantly reduced (all P values < 0.05); 33.3% of subjects at high risk and 10.0% of subjects at very high risk had achieved a TC target value; 55.6% of subjects at high risk and 40.0% of subjects at very high risk had achieved a LDL-C target value. CONCLUSION: Pitavastatin has a safe effect on blood glucose and it could be used to treat diabetic patients combined with hypercholesterolemia in China.

OBJECTIVE: To evaluate the effect of pitavastatin on high sensitivity C-reactive protein (hsCRP) in patients with hypercholesterolemia, and determine risk factors for the effect. METHODS: This study was a 12-week, multicenter, open-label, without parallel-group comparison, phase IV clinical trail. RESULTS: There were 330 subjects in the per protocol set. Contrast to the baseline, the average levels of hsCRP in all of subjects and the group without a history of receiving previous statin medication at week 12 post-treatment decreased respectively 26.4% (1.20 mg/L vs 1.68 mg/L) and 27.5% (1.21 mg/L vs 1.97 mg/L, all P < 0.05). The results of multilevel models indicated that the average levels of hsCRP reduced with the passage of treatment time, the time-varying rate of per-visit was 0.97 mg/L (95% confidence interval 0.96 - 0.98). Controlled individual background covariates, the model predicted that pulse pressure and white blood cell count on the baseline had the significant positive effects on hsCRP (P < 0.01). CONCLUSIONS: Pitavastatin decreases hsCRP in patients with hypercholesterolemia. The main risk factors for the effect are pulse pressure and white blood cell count on the baseline.

OBJECTIVE: To evaluate the safety and efficacy of pitavastatin in patients with hypercholesterolemia in China under conditions of extensive usage. METHODS: This was a 12-week, multicenter, open-label, without parallel-group comparison, phase IV clinical trial. RESULTS: There were 427 subjects in the safety set. The adverse events mainly included vomiting, myalgia and the elevations of aspartate transaminase (AST), alanine transaminase (ALT) and creatine kinase (CK), etc. The incidence of drug-related adverse events was 4.22%. There were no significant differences between pre-exposure and post-exposure average levels of renal function indicators and blood routine examination item (all P > 0.05). None of them had a high AST/ALT value, i.e. > 3 times upper limits of normal (ULN), or had a high CK value, i.e. > 10 times ULN. There were 397 subjects in the per protocol set. At week 12 post-treatment, the blood levels of total cholesterol and low density lipoprotein cholesterol (LDL-C) in subjects without previous treatment decreased 24.6% and 31.0% respectively, that of high density lipoprotein cholesterol (HDL-C) in subjects with HDL-C < 1.04 mmol/L increased 60.1% while that of triglyceride (TG) in subjects with TG > 1.70 mmol/L decreased 22.5% (P < 0.05). And 207 (92.3%) subjects were at a low risk, 46 (76.1%) subjects at an intermediate risk, 134 (47.8%) subjects at a high risk and 10 (40.0%) of subjects at a very high risk had achieved a LDL-C target value; the LDL-C goal achievement rate after switching from previous medication to pitavastatin was significant higher than that of pre-switching. CONCLUSION: Pitavastatin demonstrates positive safety and efficacy. It may be used for the treatment of patients with hypercholesterolemia in China.

OBJECTIVE: To explore the relationship and interaction of elevated fasting glucose and hypertension on cardiocerebral vascular disease. METHODS: 10 054 males and females were recruited for our cross-sectional study during May 2007 to August 2007. Unconditional logistic regression was used to analysis the relationship between fasting glucose and hypertension on cardiocerebral vascular disease. A product of fasting glucose and hypertension was added to the logistic regression model to evaluate the multiplicative interaction and relative excess risk of interaction (RERI), attributable proportion (AP) of interaction and synergy index (S) was applied to evaluate the additive interaction of the two factors. Bootstrap was used to calculate 95% confidence intervals (CI) of RERI, AP and S. RESULTS: After adjusting age, gender, smoking, drinking, body mass index (BMI) and region, the product of fasting glucose and hypertension was not statistically significant, which means there was no multiplicative interaction between the two. But the additive indexes RERI, AP and S with 95%CI of diabetes and hypertension were 0.64 (0.03, 1.25), 0.27 (0.01, 0.47) and 1.83 (1.02, 5.13) respectively, which means significant additive interaction was shown between the two on cardiovascular disease but not no stroke. And there were no additive interaction between impaired fasting glucose on cardiovascular disease or stroke. CONCLUSIONS: Hypertension was independently related to cardiovascular disease and stroke in Beijing citizens, and diabetes were independently related to stroke. There was additive interaction between diabetes and hypertension on cardiovascular disease.

A subgroup of children diagnosed with autism experience developmental regression featured by a loss of previously acquired abilities. The pathogeny of autistic regression is unknown, although many risk factors likely exist. To better characterize autistic regression and investigate the association between autistic regression and potential influencing factors in Chinese autistic children, we conducted an ambispective study with a cohort of 170 autistic subjects. Analyses by multiple logistic regression showed significant correlations between autistic regression and febrile seizures (OR = 3.53, 95% CI = 1.17-10.65, P = .025), as well as with a family history of neuropsychiatric disorders (OR = 3.62, 95% CI = 1.35-9.71, P = .011). This study suggests that febrile seizures and family history of neuropsychiatric disorders are correlated with autistic regression.

OBJECTIVE: To investigate the smoking cessation rate and its related factors in cardiovascular patients after percutaneous coronary intervention. METHODS: A cross-sectional survey of 1241 outpatients or inpatients fulfilling the inclusion criteria was conducted at 14 hospitals across China. RESULTS: The survey population mainly consisted of middle-aged male patients with an average age of (59.9 ± 10.7) years old. Their median time after surgery was 1.5 years. Among them, 77.4% tried to quit smoking while 55.4% succeed. The elder men were more likely to try to quit smoking and succeed eventually (OR values: 1.02 vs 1.03). The higher number of cigarettes smoked daily, the greater possibility of trying to quit smoking (OR = 1.03), but less likely to quit smoking eventually (OR = 0.97). Furthermore the years of smoking and cessation motivation had impacts on the cessation behaviors as well. CONCLUSION: Smoking cessation was achieved in more than half of the patients at one year after PCI. Age, years of smoking, daily number of cigarettes, concurrent diseases and physician recommendations are the influencing factors of smoking cessation.

OBJECTIVE: To observe the prevalence, awareness, treatment and control rate of hypertension and to evaluate the 10-year absolute risk of coronary heart disease(CHD) and ischemic cardiovascular disease(ICVD) in Chinese cardiovascular physicians. METHODS: A total of 4032 cardiovascular physicians (28 to 79 years old) from 386 hospitals in 31 provinces, autonomous regions and municipalities were randomly selected and received an epidemiologic survey of prevalence, awareness, and control of hypertension and evaluations of CHD and ICVD risk. RESULTS: The prevalence of hypertension in Chinese cardiovascular physicians was 13.1%. The awareness rate of hypertension in Chinese cardiovascular physicians was 81.7%. Hypertension treatment rate was 69.6% and blood pressure control rate was 44.6%. The prevalence of hypertension was higher in male physicians than in female physicians before the age of 55 years old. Ten-year absolute risk of CHD and ICVD was 0.08 and 0.03 in hypertensive physicians compared to 0.03 and 0.01 in non-hypertensive physicians. CONCLUSIONS: The results show suboptimal awareness, treatment and control rate in Chinese cardiovascular physicians for their own hypertension status.Physicians suffering from hypertension face higher risk for cardiovascular disease. It is therefore necessary to improve the self-monitoring of blood pressure in Chinese cardiovascular physicians.

OBJECTIVE: To investigate the relationship between marital status and prevalence of peripheral arterial disease (PAD) among Beijing residents. METHODS: From May to August 2007, 10 054 residents were interviewed to collect demographic and biochemistry information. Generalized linear mixed model was used to determine the relationship between marital status and prevalence of PAD in terms of OR and corresponding 95% confidence intervals. RESULTS: After adjusting the traditional risk factors including age, area, lipid, serum glucose, blood pressure, central obesity, smoking, drinking and physical activities for PAD, relationship between marital status and prevalence of PAD was found both at the female and male groups of those with 45 years or older. Compared with married men, OR and 95% confidence interval of PAD for unmarried men were 1.56 (0.39 - 6.35) and 1.61 (0.77 - 3.35) for those with 45 years younger and older respectively, while compared with married women, OR and 95% confidence interval of PAD for unmarried women were 0.75 (0.22 - 2.57) and 1.78 (1.23 - 2.58) for those with 45 years younger and older respectively. Significant differences (all P < 0.01) were found between married and unmarried women of 45 years or older in terms of age, waist circumstances, systolic blood pressure, fasting glucose, total cholesterol, low-density lipoprotein and smoking. CONCLUSIONS: Peripheral arterial disease was related to marital status for women of 45 years or older among Beijing residents. Estrogen level and the distribution of other PAD risk factors might contribute to the observed finding.

OBJECTIVE: To investigate the prevalence and hazard of smoking in Chinese cardiovascular physicians. METHODS: A total of 4032 cardiovascular-certified physicians were recruited from 386 medical centers in all 31 provinces and municipalities in mainland China between June 1 2008 and August 31 2008. RESULTS: The prevalence of smoking in Chinese cardiovascular physicians was 15.2% (95% CI 14.1% - 16.3%), 609 (29.8%) (95% CI 27.8% - 31.8%) for men was much higher than 3 (0.2%) (95% CI 0.1% - 0.4%) for women (P < 0.01). The prevalence of heavy male smoking was 6.9% (95% CI 5.9% - 8.1%) and there was no heavy female smoker. Significant geographic differences were observed among male smokers. Higher smoking rates were seen in the northwest and southwest parts of China. There were significant differences in prevalence of male smoking between areas. The prevalence of history of hypertension, diabetes mellitus and hypercholesterolemia in male smoking group were all significantly higher than in male non-smoking group (all P < 0.01). The 10-year absolute risk and relative risk of coronary heart disease and ischemic cardiovascular disease estimated by Framingham model and Chinese model were all significantly higher in smoking group than in non smoking group (all P < 0.01). CONCLUSION: The prevalence of smoking in Chinese cardiovascular physicians is relatively high and smoking cessation should be targeted in this population.
