Objective:To investigate plasma levels of fibrinopeptide A(FPA)and platelet alpha-granule membrane glycoprotein 140(GMP-140), and to analyze the changes of coagulation activity in elderly patients with primary microvascular angina(PMVA).Methods:In this prospective case-control study, a total of 45 elderly patients(aged 60-80 years, 27 males and 18 females)admitted to our hospital from Jan.2019 to Dec.2020 were diagnosed as PMVA(as microvascular angina group)by clinical symptoms, electrocardiogram, dynamic electrocardiogram and coronary angiography.Forty-three age-and sex-matched elderly subjects who took a medical check-up and had no primary microvascular angina were included as the control group.Plasma levels of FPA, GMP-140 and high-sensitivity C-reactive protein were determined.The levels of systolic blood pressure, diastolic blood pressure, platelet, fasting blood glucose, triglyceride, total cholesterol, high-density lipoprotein and low-density lipoprotein, uric acid, renal function and liver function were detected.Results:The FPA level was higher in the PMVA group than in the control group[(430.32±364.05)μg/L vs.(263.73± 118.29)μg/L, t=2.913, P<0.01]. There was no difference in GMP-140 level between the PMVA group and the control group[(5.78±3.92)μg/L vs.(6.95±1.91)μg/L, t=-1.790, P>0.05]. The high-sensitivity C-reactive protein level was higher in the PMVA group than in the control group[(3.33±5.70)mg/L vs.(0.81±0.86)mg/L, t=2.927, P<0.01]. Conclusions:Compared with the control group, the FPA level is significantly increased with elevated coagulation activity in patients with primary microvascular angina.The increased inflammatory state in the PMVA group might promote the occurrence and development of microvascular angina, but whether the inflammatory state promotes the enhancement of coagulation activity needs further study to confirm.

Objective To observe the effects of stromal cell-derived-factor-1(SDF-1) on the function of endotheli?al progenitor cells(EPCs)of peripheral blood in patients with diabetes, and to discuss the effects of PI3K/AKT signaling path?way on the role of SDF-1 in EPCs. Methods The peripheral blood samples (30 mL) were collected in 10 diabetes patients (DM group) and 10 healthy controls (HC group). (1) The 100μg/L SDF-1 was added in intervention group. EGM-2MV was added in non-intervention group. The Boyden chamber and in vitro angiogenesis kit were used to analyze the migration and in vitro angiogenesis of EPCs. (2) Cultured EPCs were divided into blank control group, 1μg/L SDF-1 group, 10μg/L SDF-1 group, 100μg/L SDF-1 group, pure AMD3100 group and 100μg/L SDF-1+AMD3100 group. AKT protein expression lev?els of endothelial progenitor cells were detected by Western blot assay in each group. Results (1) Without intervention with SDF-1, EPCs’migration and angiogenesis ability were lower in DM group than those in HC group. After intervention with SDF-1, the migration and angiogenesis ability were enhanced in two groups, but the increased level was higher in DM group than that of HC group. (2) Under the same concentration, AKT protein expression level was significantly lower in DM group than that in HC group (P<0.01). AKT protein expression levels were increased with the increased levels of SDF-1 in DM group and HC group (P<0.05). AKT protein expression was significantly lower in 100μg/L SDF-1+AMD3100 group than that of 100μg/L SDF-1 group (P<0.05). Conclusion SDF-1 can increase the chemotactic migration and angiogenesis ability of EPCs in peripheral blood, especially for patients with diabetes. The effects of SDF-1 on EPCs were related to the PI3K/AKT signaling pathway.

Objective To investigate the effect of different etiology on the serum level of carbohydrate antigen 125 (CA125) in elderly patients with chronic congestive heart failure (CHF), and to assess any correlation of CA125 with serum level of B-type natriuretic peptide (BNP). Methods The 155 aged patients with New York Heart Association (NYHA) class Ⅲ or Ⅳ were enrolled and grouped into four reasons of hypertension, coronary heart disease (CHD), cardiomyopathy and other reasons, and 25 healthy old persons as control.CA125 and BNP levels were measured by automatic chemiluminescent immunoassay and enzyme immunoradiometric assay, respectively. Results CA125 level in patients with CHF was (83.4±6.6)U/L for hypertension, (36.8±1.4)U/L for CHD, (38.1±1.6)U/L for cardiomyopathy and (38.4±1.4)U/L for other reasons, which significantly higher than for healthy controls [(14.3±1.15) U/L, P＜0.05].Especially, CA125 level in hypertension group was notable higher than in other reasons of group (P＜0.05), and was positively related to BNP level (r=0.67,P＜0.05). Conclusions Serum CA125 level is a predictor for clinical pathogen of CHF.Therefore, it may be a useful additional marker for the evaluation of clinical treatment of these patients

Objective : To explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province, so as to provide scientific evidence for the prevention and control of hypertension. Methods: Data were collected from 10 national surveillance sites in Zhejiang Province in the 2018 China Chronic Disease and Risk Factors Surveillance. The multivariate logistic regression model was used to explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province. Results : Among 5 908 people included, 2 641 were males, accounting for 50.38%; and 3 267 were females, accounting for 49.62%. There were 2 721 cases of hypertension ( 28.54% ). The number of the cases with no, light and excessive alcohol consumption was 3 945, 1 117 and 846, accounting for 66.28%, 23.65% and 10.07%, respectively, after complex sampling weighting. The results of the multivariate logistic regression model showed that compared with those with no alcohol consumption, the adults with excessive alcohol consumption had higher risk of hypertension ( OR=2.126, 95%CI: 1.649-2.741 ); men with light ( OR=1.875, 95%CI: 1.075-3.270 ) and excessive alcohol consumption ( OR=2.752, 95%CI: 2.021-3.748 ) had higher risk of hypertension; the 18-<45-year-old adults with light ( OR=2.441, 95%CI: 1.171-5.087 ) and excessive alcohol consumption ( OR=3.368, 95%CI: 1.609-7.049 ), and the ≥60-year-old adults with excessive alcohol consumption ( OR=1.632, 95%CI: 1.174-2.269 ) had higher risk of hypertension. Conclusions Light and excessive alcohol consumption are associated with hypertension in Zhejiang adults. The association is stronger between excessive alcohol consumption and hypertension than between light alcohol consumption and hypertension.

Objective: To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension. Methods: Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model. Results: Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years. Conclusions Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.

Objective: To examine the correlation between frailty and lifestyle factors among middle-aged and elderly populations, so as to provide insights into the management of frailty among middle-aged and elderly populations. Methods : Middle-aged and elderly residents at ages of 45 ot 69 years were recruited using the convenient sampling method from seven townships in Changxing County of Zhejiang Province from 2019 to 2020. The demographic characteristics and lifestyle factors were collected using questionnaires, and the frailty was measured using the Chinese version of Tilburg Frailty Indicator ( TFI ). Factors affecting frailty were identified among middle-aged and elderly populations using the multivariable logistic regression model. Results: A total of 7 170 residents were surveyed, including 2 780 males ( 38.77% ) and 4 390 females ( 61.23% ), which had a median age of 56 (interquartile range, 10) years. The median frailty score was 2 (interquartile range, 3 ) among the study subjects, and the median frailty score was 2 ( interquartile range, 2 ) among residents at ages of 45 to 59 years, and 2 (interquartile range, 3) among residents at ages of 60 to 69 years. The overall detection of frailty was 16.07%, and the detection of frailty was 13.52% among subjects at ages of 45 to 59 years and 21.01% among subjects at ages of 60 to 69 years. Multivariable logistic regression analysis identified physical activity ( OR=0.826, 95%CI: 0.719-0.949 ) and sleep quality ( OR: 3.376-11.493, 95%CI: 2.907-15.808 ) as factors affecting frailty among middle-aged and elderly residents. Following age stratification, physical activity ( OR=0.817, 95%CI: 0.681-0.981 ) and sleep quality ( OR: 3.076-11.566, 95%CI: 2.518-18.216 ) as factors affecting frailty among subjects at ages of 45 to 59 years, while sleep quality ( OR: 3.777-11.827, 95%CI: 3.002-18.547 ) significantly correlated with frailty among residents at ages of 60 to 69 years. Conclusion Physical activity and sleep quality are associated with the risk of frailty among middle-aged and elderly populations.

Objective:To investigate the changes in cognitive and behavioral function in patients with cerebral small vessel disease and their correlation with serum homocysteine (Hcy) and cystatin C (CysC) levels.Methods:Ninety-four patients with cerebral small vascular disease who received treatment in Zhejiang Xin'an International Hospital from March 2019 to March 2021 were included in the observation group. An additional 80 healthy controls who concurrently received physical examination were included in the control group. The Mini-Mental State Scale (MMSE) and the Montreal Assessment Scale (MoCA) were used to evaluate cognitive function. The activity of daily living (ADL) was used to evaluate behavioral function. Enzyme-linked immunosorbent assay was used to measure serum Hcy and CysC levels. MMSE score, MoCA score, ADL score, serum Hcy and CysC levels were compared between the two groups. The receiver operating characteristic (ROC) curve was used to analyze the sensitivity and specificity of serum Hcy and CysC levels in the diagnosis of cerebral small vessel disease. Pearson correlation analysis was performed to analyze the correlation between serum Hcy and CysC levels and cognitive behavioral function.Results:MMSE score, MoCA score, and ADL score in the observation group were (21.21 ± 2.87) points, (20.18 ± 3.25) points, and (34.32 ± 5.45) points, which were significantly lower than (28.23 ± 1.02) points, (28.45 ± 0.89) points and (76.35 ± 8.29) points in the control group ( t = 20.78, 22.05, 40.03, all P < 0.05). Serum Hcy and CysC in the observation group were (16.28 ± 2.97) μmol/L and (1.21 ± 0.23) mg/L, which were significantly higher than (8.35 ± 1.76) μmol/L and (0.56 ± 0.12) mg/L in the control group ( t = 20.95, 22.77, both P < 0.05). ROC curve analysis showed that the sensitivity and specificity of serum Hcy in diagnosing cerebral small vessel disease were 85.29% and 53.85%, respectively; the sensitivity and specificity of serum CysC in diagnosing cerebral small vessel disease were 81.54% and 41.38%, respectively. Pearson correlation analysis revealed that serum Hcy level was linearly negatively correlated with MMSE score, MoCA score, and ADL score ( r = -0.79, -0.68, -0.71, all P < 0.05); serum CysC level was linearly negatively correlated with MMSE score, MoCA score, and ADL score ( r = -0.67, -0.75, -0.78, P < 0.05). Conclusion:The cognitive and behavioral function of patients with cerebral small vessel disease are decreased, and serum Hcy and CysC levels are increased. Serum Hcy and CysC levels are closely related to the cognitive and behavioral function of patients with cerebral small vessel disease.

Objective To access the prevalence of type 2 diabetes mellitus ( T2DM) and its associated risk factors among adults with obesity in Zhejiang province. Methods The enrolled subjects were selected among local residents aged≥18 years with body mass index≥28 kg/m2 from 15 counties by multi stage stratified cluster random sampling from July to November, 2010. Each participant was required to attend complete questionnaire, physical examination, and testing overnight fasting blood specimen. Results A total of 1 351 residents were enrolled, including 613 males and 738 females. The prevalence of T2DM in adult population with obesity was 15. 03%, being 14. 03% in male, and 15. 85% in female;and that in urban area was 16. 64%, and in rural area was 13. 93%. Data from multivariable logistic regression showed that factors such as ageing (OR=1. 473, 95% CI 1. 243-1. 747), a family history of T2DM(OR=8. 945, 95% CI 5. 481-14. 598), staple food intake (OR=1. 185, 95% CI 1. 017-1. 380), triglyceride(≥1. 7 mmol/L, OR=1. 542, 95%CI 1. 066-2. 232) were risk factors of T2DM;while annual income(OR=0. 695, 95%CI 0. 544-0. 888), and milk intake(OR=0. 750, 95%CI 0. 567-0. 993) were shown as protective factors. Conclusion The prevalence of T2DM in adults with obesity was raised, ageing, a family history of T2DM, staple food intake, and dyslipidemia appeared to be major risk factors for T2DM.

Objective To evaluate the effect of the different Child-Pugh classification on the recurrence and survival of hepatocellular carcinoma (HCC) recipients after liver transplantation. Methods Clinical data of 125 HCC recipients undergoing liver transplantation were retrospectively analyzed. The 3-year disease-free survival (DFS) and overall survival (OS) rates were calculated by Kaplan-Meier survival curve. The independent risk factors probably affecting the recurrence and survival of HCC recipients after liver transplantation were identified by using Cox's proportional hazards regression model. Results The median follow-up time was 25.6 months. The 3-year DFS and OS rates were 68.4% and 65.7% for all patients. The 3-year DFS and OS rates in 113 patients with Child-Pugh class A/B HCC were 68.6% and 66.2%, whereas 66.7% and 65.6% for 12 patients with Child-Pugh class C HCC with no statistical significance (all P>0.05). Cox's proportional hazards regression model demonstrated that vascular invasion (P=0.001)and the number of tumors>3 (P=0.025) were the independent risk factors for the postoperative recurrence of HCC in recipients undergoing liver transplantation. Alpha fetoprotein (AFP)>400μg/L (P=0.035), vascular invasion (P=0.031) and number of tumors>3 (P=0.008) were the independent risk factors affecting the survival of HCC patients. Conclusions The postoperative prognosis does not significantly differ between Child-Pugh class C and A/B HCC patients after liver transplantation. AFP, vascular invasion and number of tumors are the risk factors affecting the clinical prognosis of HCC patients after liver transplantation. Liver transplantation is an efficacious treatment for HCC patients with Child-Pugh class C.
