ABSTRACT
Objective@#To identify the incidence of hypertension, overweight/obesity in middle-aged population in China, and explore their impact on cardiovascular events.@*Methods@#From 2009 to 2010, 12 areas were sampled in China, and about 1 000 subjects aged 35 - 64 from each area were enrolled to collect the basic information, physical examination and blood tests were also performed. From 2016 to 2017, data from 8 835 subjects, who completed the 6 years follow-up, were analyzed.Blood pressure and body mass index(BMI) at both baseline and the follow-up, as well as incidence of hypertension, overweight and obesity, were calculated. Cox proportional hazard model was used to investigate the impacts of hypertension, overweight and obesity on cardiovascular events after adjusting confounders.@*Results@#At the end of follow-up, both BMI and systolic and diastolic blood pressure increased significantly compared with the baseline levels (all P<0.001). The cumulative incidence of hypertension, overweight and obesity within 6 years was 39.3%(1 146/2 918), 11.5%(406/3 544) and 4.3%(302/7 025), respectively. Compared with subjects with both normal BMI and blood pressure, people with overweight, obesity, hypertension, overweight with hypertension, and obesity with hypertension faced significantly increased risk of cardiovascular disease (HRs (95%CIs) were 2.394(1.130-5.073), 3.341(1.454-7.674), 6.047(2.978-12.279), 5.808(2.924-11.539) and 8.716(4.391-17.302), respectively, all P<0.05), after adjusting for other confounders.@*Conclusions@#The incidence of overweight, obesity, and hypertension is high in middle-aged people in China. Overweight, obesity and hypertension are associated with significantly increased risk of cardiovascular events during the 6 years follow up.
ABSTRACT
Objective@#To evaluate the effects of standardized management of hypertension on blood pressure control of hypertension patients with diabetes mellitus in workplace population.@*Methods@#Taking the type and size of workplace into consideration, 61 work sites were selected in different provinces by using epidemiological field trial method. In each selected province, 2-4 work sites with similar economic and medical conditions were chosen, among which 1-3 were designated as the intervention group and the other one as the control group. In total, 443 patients with hypertension and diabetes mellitus were included, with 347 patients in the intervention group and 96 patients in the control group. After training, doctors conducted standardized management for patients in the intervention group for a period of 24 months, following up with them regularly once a month, and recorded changes in blood pressure, risk factors, target organ damage, and treatment, while the control group had no special intervention, and relevant information was collected only at baseline and 24 months. Blood pressure, blood pressure control rate, and blood glucose changes were compared between the two groups.@*Results@#After receiving standardized management of hypertension, the control rate of hypertension for patients with both hypertension and diabetes mellitus in the intervention group increased from 24.2% to 63.7% (P<0.05) and the participants’ blood pressure also significantly decreased, by 10.2 (11.9-8.4) mmHg (1 mmHg=0.133 kPa) for systolic blood pressure and 7.7 (8.8-6.6) mmHg for diastolic blood pressure (P<0.05); moreover, the blood glucose also decreased slightly (P<0.001). In addition, the control rate of blood pressure increased to 63.7% with the increase of management time. In the control group, the control rate of hypertension increased to 46.9% (P<0.05) and the systolic and diastolic blood pressure decreased by 5.6 (8.9-2.2) and 4.5 (6.6-2.4) mmHg (P<0.05).@*Conclusions@#The standardized management of hypertension in the workplace can effectively reduce overall blood pressure levels and improve the control rate of hypertension in the working population.

ABSTRACT
BACKGROUND:Lymph-targeted tracing and therapy based on carbon nanotubes have been one of the hottest researches on targeting tumor diagnosis and treatment. To evaluate the accumulation of carbon nanotubes in axil ary lymph node can provide experimental evidences for developing nano-tracers and drug carriers which are more lymph-specific and more biocompatible. OBJECTIVE:To study the accumulation of the intravenously injected carboxylated single-wal ed carbon nanotubes in axil ary lymph nodes of Sprague-Dawley rats, and to evaluate their effect on blood cel s. METHODS:Sixty-four Sprague-Dawley rats were randomly divided into two groups. Rats in testing group were injected with carboxylated single-wal ed carbon nanotubes suspension (2 mg/kg), while those in control group were injected with 5%glucose solution (1 mL/kg), both through the tail vein, three times per week. Four periods of 7, 60, 90 and 120 days were set (the 120-day period referred to 90 days of administration fol owed by 30 days of drug withdrawal). At the end of each period, eight rats from each group were randomly picked out, to col ect blood samples via the abdominal aorta for blood routine test. Final y the axil ary lymph nodes were observed, and the lymph node samples of rats in the testing group were col ected and analyzed at 120 days by transmission electron microscope. RESULTS AND CONCLUSION:Compared with the control group, black staining of axil ary lymph nodes of rats in testing group was not obvious at the end of the 7-day period. However, with the increase of the dosing periods, the lymph nodes of the rats in the testing group became enlarged, firm and black stained, coupled with a significant rising in the percentage of blood neutrophils. After 30 days of drug withdrawal, the size of the rat axil ary lymph nodes was reduced and black staining partly faded, with the decreasing of blood neutrophil percentage. Under the transmission electron microscope, abundant carboxylated single-wal ed carbon nanotubes were uptaken by lymphocytes to form a large number of phagocytic vacuoles after drug withdrawal for 30 days. It indicates that the short-term tracing of rat axil ary lymph nodes by carboxylated single-wal ed carbon nanotubes injected through the tail vein is relatively weak, while the long-term intravenous injection can cause their accumulation in rat axil ary lymph nodes, coupled with the increase of neutrophils;after drug withdrawal, the carboxylated single-wal ed carbon nanotubes can be slowly cleared by the lymph nodes.
ABSTRACT
Objective To establish the expression profiles of microRNA (miRNA) in SMMC-7721 and CCC-HEL-1 cell lines in order to provide new clues to study the mechanism of miRNA function in hepatocellular carcinoma (HCC) and its treatment. Methods SMMC-7721 and CCC-HEL-1 cell lines were cultured in vitro. Total RNAs were extracted by TRIzol, followed by RNA quantification and quality control. The RNAs were used to detect the expression of miRNA in these two cell lines by miRNA array. The miRNA of interest was then verified by real-time PCR. Results In total,238 differentially expressed miRNAs were found, including 154 overexpressed and 84 underexpressed miRNAs. 64 miRNAs were upregulated more than 4 times and26 miRNAs were upregulated more than 10 times. 22 miRNAs were downregulated more than 4 times 10 miRNAs weredownregulated more than 5times, and 1 miRNA was downregulated more than 10 times. Real-time PCR validation suggested that has-miR-205 and has-let-7f in liver cancer increased by 2. 7 and 2. 3 times, respectively.Conclusion There are differences in the expression of miRNA between the SMMC-7721 and CCC-HEL-1 cell lines and the profiles of miRNA expression were established for both cell lines. It was found that has-miR-205 and has-let-7f were upregulated in liver cancer.
