Objective To explore the correlation between left ventricular hypertrophy (LVH) and dynamic parameters of blood pressure as well as blood pressure variation in patients with essential hypertension (EH). Methods From January to September, 2013, 581 patients with EH were divided into hypertrophy group (n=161) and non-hypertrophy group (n=420) according to the left ventricular mass index (LV-MI). The clinical data, biochemical indexes and dynamic parameters of blood pressure were compared, and the multiple factors regression was used to analyze the risk factors of LVH. Results The incidence of LVH was higher in women than in men (χ2=4.836, P=0.03), the level of blood uric acid was higher in the hypertrophy group than in the non-hypertrophy group (t=-11.540, P<0.001). The clinic systolic blood pressure was higher in the non-hypertrophy group (t=-3.805, P<0.001). There was significantly difference in 24-hour systolic blood pres-sure load, systolic blood pressure drops at night and average systolic blood pressure between two groups (t>2.770, P<0.05). Multi-factor Lo-gistic regression analysis showed that gender (OR=1.674, P=0.044) and 24-hour systolic blood pressure load (OR=1.021, P=0.003) associat-ed with LVH. Conclusion The occurrence of LVH in patients with EH was closely related to the 24-hour systolic blood pressure load, and was higher in women than in men.

To study the effect of Tibetan medicine Zuotai on the activity, protein and mRNA expression of CYP1A2 and NAT2, three different doses (1.2, 3.8 and 12 mg x kg(-1)) of Zuotai were administrated orally to rats once a day or once daily for twelve days, separately. Rats were administrated orally caffeine (CF) on the second day after Zuotai administration, and the urine concentration of CF metabolite 5-acetylamino-6-formylamino-3-methyl-uracil (AFMU), 1-methyluric acid (1U), 1-methylxanthine (1X), 1, 7-dimethylxanthine (17U) at 5 h after study drug administration was determined by RP-HPLC. The activity of CYP1A2 and NAT2 was evaluated by the ratio of metabolites (AFMU+1X+1U)/17U and the ratio of AFMU/(AFMU+1X+1U), respectively. The protein and mRNA expression of CYP1A2 and NAT2 were determined by ELISA and RT-PCR method, respectively. After single administration of Zuotai 3.8 mg x kg(-1) and repeated administration of Zuotai 3.8 and 12 mg x kg(-1), the activity of CYP1A2 and NAT2 decreased significantly compared with control group and there was no significant difference between other dose group and control group. The protein expression of CYP1A2 was significant lower than that in control group after repeated administration of Zuotai 12 mg x kg(-1), and the mRNA expression of CYP1A2 decreased significantly compared with that of control group after single administration of Zuotai 3.8 mg x kg(-1) and repeated admistration of Zuotai 12 mg x kg(-1), separately. The protein expression of NAT2 decreased significantly compared with that of control group after single and repeated administration of Zuotai 3.8 mg x kg(-1), respectively, and the mRNA expression of CYP1A2 decreased significantly compared with control group after single administration of Zuotai 3.8 mg x kg(-1). This study found that Tibetan medicine Zuotai had significant effect on the activity, protein and mRNA expression of CYP1A2 and NAT2.

Objective:To study the clinical risk factors for osteoporotic fracture (OF) risk prediction in patients with type 2 diabetes mellitus (T2DM) using adjusted fracture risk assessment tool (FRAX) .Methods:A cross-sectional study of 429 patients with T2DM who were hospitalized in the Department of Endocrinology and Geriatrics of the Affiliated Huaian No. 1 People’s Hospital of Nanjing Medical University from Sep. 2019 to Sep. 2020 was conducted. Participants were divided into OF low-risk group and OF high-risk group. Participant characteristics (age, gender, height, weight, waist, blood pressure, history of drug treatment, serum glucose, glycosylated hemoglobin, total cholesterol, low-density lipoprotein cholesterol (LDL-C) , high-density lipoprotein cholesterol (HDL-C) , triglyceride, serum uric acid, alkaline phosphatase, and thyroid stimulating hormone levels, urine protein/creatinine ratio, urea, creatinine and TPOAB) and dual energy x-ray absorptiometry results were obtained and analyzed. Logistic regression model was used to investigate the relationship between the OF risk of T2DM assessed by adjusted FRAX and clinical risk factors.Results:Patients in the OF high-risk group accounted for 9.09% of the subjects. After adjustment for other variables, the duration of diabetes was still positively associated with significantly elevated risk of OF assessed by adjusted FRAX ( OR 7.660, 95% CI 1.661-35.334, P=0.009) , whereas the blood uric acid was negatively associated with significantly elevated risk of OF assessed by adjusted FRAX ( OR 0.345, 95 % CI 0.128-0.928, P=0.035) .Likewise, LDL-C levels decreased the odds of the risk of OF assessed by adjusted FRAX ( OR 0.316, 95 % CI 0.114-0.881, P=0.028) . There was no significant relationship between alkaline phosphatase ( OR 1.902, 95 % CI 0.904-4.004, P=0.090) as well as total cholesterol ( OR 0.297, 95% CI 0.056~1.560, P=0.151) levels and the elevated risk of OF assessed by adjusted FRAX. Conclusion:Diabetes duration could be a risk factor for OF risk prediction in patients with T2DM using adjusted FRAX, and serum uric acid and LDL-C could be protective factors for OF risk prediction in patients with T2DM using adjusted FRAX.

Objective:To explore the association of hemoglobin(HGB) levels with bone mineral density(BMD) and osteoporosis in patients with type 2 diabetes mellitus(T2DM).Methods:A cross-sectional study was conducted in 364 patients with T2DM who were hospitalized in the Department of Endocrinology and Geriatrics of the Affiliated Huaian No. 1 People′s Hospital of Nanjing Medical University from September 2019 to September 2020. Participants were stratified into tertiles(lower, middle, and upper) according to femoral BMD determined by dual-energy X-ray absorptiometry. Demographic characteristics, medical history, chronic diabetes complications, and comorbid conditions were compared among the 3 groups. The association between hemoglobin levels and BMD/osteoporosis was examined using multivariable logistic regression analyses. Interaction and stratified analyses were conducted according to age, body mass index(BMI), duration of diabetes, estimated glomerular filtration rate(eGFR), glycosylated hemoglobin(HbA 1C), total cholesterol(TC), triglycerides(TG), high-density lipoprotein-cholesterol(HDL-C), low-density lipoprotein-cholesterol(LDL-C) and uric acid(UA). Results:After adjusting for age, BMI, and duration of diabetes, there were no significant differences observed in the association between hemoglobin levels and BMD or osteoporosis among postmenopausal women with T2DM(all P>0.05). After adjusting for age, BMI, duration of diabetes, and eGFR, men aged≥50 years with hemoglobin≥130 g/L showed a positive association between hemoglobin level and femoral neck BMD compared to those with hemoglobin<130 g/L( β=0.057, 95% CI 0.014-0.100, P=0.011). However, no significant associations were observed between hemoglobin level and BMDs at the total hip or lumbar spine(L1-L4), nor the risk of osteoporosis(all P>0.05). Stratified analyses revealed no significant differences in the subgroups classified based on age, BMI, diabetes duration, eGFR, HbA 1C, TC, TG, HDL-C, LDL-C, and UA(all interaction P>0.05). Conclusion:In males aged 50 and above with T2DM, elevated hemoglobin levels may be a protective factor for femoral neck bone density.
