ABSTRACT

Platelets not only have hemostatic function, but can also directly or indirectly recognize pathogenic microorganisms and the signals they produce to capture and destroy them through membrane receptors. They can collaborate with various components of the body's immune system by releasing of intraplatelet particulate matter, cytokines and chemokines to perform bactericidal functions. And it can also play a bactericidal role by swallowing pathogens, releasing antimicrobial proteins and chemokines and activating and enhancing other specialized anti-inflammatory cells bactericidal effect, such as leukocytes and so on. However, the bacteriostatic composition and bacteriostatic mechanism of platelets remain unclear, so attention should be paid to the immune mechanism and bacteriostatic effect of platelets.

ABSTRACT

Objective@#To investigate statin adherence and influencing factors in hyperlipidemia patients treated in community health centers.@*Method@#This study enrolled hyperlipidemia patients for whom statins were newly prescribed by doctors at 7 community health centers. Baseline and follow-up information was collected by well-trained investigators by telephone. Adherence to statins was evaluated after 3 months of follow-up.@*Results@#We included 104 hyperlipidemia patients for whom statins were newly prescribed between July and December 2017; of these, 48.1% knew about the complications of hyperlipidemia and 84.6% thought it was necessary to take lipid-lowering drugs; however, 63.5% were concerned about the side effects of these drugs. After 3 months of follow-up, 40.4% of patients had stopped taking statins, and 60.5% were nonadherent to the statin prescriptions. The analysis of influencing factors showed that hyperlipidemia history less than 6 months (OR=9.644, 95%CI: 3.214-28.943, P<0.001) and having to take more than 2 pills per day (OR=3.536, 95%CI: 1.254-9.972, P=0.017) were positively associated with cessation of statin use, while thinking it necessary to take lipid-lowering drugs (OR=0.126, 95%CI: 0.018-0.883, P=0.037) was negatively associated with cessation of statin use. Meanwhile, hyperlipidemia history for less than 6 months (OR=3.368, 95%CI: 1.283-8.847, P=0.014) was positively associated with poor statin adherence.@*Conclusion@#Poor statin adherence was observed in patients treated in community health centers. Health knowledge awareness, attitude toward chronic disease treatment, i.e., lipid-lowering treatment, and pill burden might influence statin adherence.

ABSTRACT

Objective To evaluate the effect of interventions for improving the management of cardiovascular risk factors in general practitioners. Methods Interventions were conducted in thirty-five community health service centers in Chaoyang District of Beijing using simplified clinical pathways,clinical decision support systems, service quality evaluation index and feedback mechanism, and quality-related motivation system. The research was divided into three periods, which were indicated as before the interventions (2014.1-6), after the first intervention (2014.8-10), and after the second intervention (2014.12-2015.2), according to the community service center outpatient clinic, the computer randomly selected 2 100, 2 089 and 2 052 subjects. With the method of retrospective case review, historical case records of each selected case were extracted, and the changes in KPIs before and after interventions were evaluated.Results After two cycles of intervention,compared with before the interventions,the capability of general practitioners to record hypertension(99.9% vs.70.5%,χ2=708.9),diabetes(99.6% vs.41.5%,χ2=1691.1),hyperlipidemia(99.5% vs.37.0%,χ2=1854.9),coronary atherosclerotic heart disease(CHD)(99.6% vs. 54.3%, χ2=1190.9), and cerebral hemorrhagic stroke (99.4% vs. 39.7%, χ2=1736.2) had significantly increased (P<0.001). Records of other risk factors, for instance, height and weight (81.4% vs. 72.2%, χ2=50.3),smoking(70.0% vs.0.1%,χ2=2 179.2),and health education including recommended physical activity (75.0% vs. 68.2%, χ2=24.0) and weight control (75.4% vs. 16.2%, χ2=1 467.1) significantly increased (P<0.001). The proportion of patients with hypertension who did not use antihypertensive drugs was 31.6% before the intervention;in the first period of intervention,it reduced to 20.2%,and in the second period after the intervention it was 25.8%. Cases of CHD, stroke, diabetes, patients taking aspirin, beta blockers, angiotensin converting enzyme inhibitors(ACEI)or angiotensin receptor blockers(ARB)in proportion to the class of drugs, and statins increased (P<0.05); the coronary atherosclerosis heart disease patients with beta-blockers utility ratio was 20.2% before the intervention, and in the second cycle it was up to 27.9% after the intervention;for patients with diabetes statins utility ratio was 32.1% before the intervention,and in the second cycle it was up to 40.9% after the intervention.Conclusion Adoption and implementation of a series of interventions such as simplified clinical pathways,clinical decision support systems,service quality evaluation index and feedback mechanism, and quality-related motivation system will be beneficial to improve the capability of general practitioners to manage the cardiovascular disease risk factors,which are implied to be effective methods for managing chronic diseases.

ABSTRACT

@#To analyze the relationship among ambulatory blood pressure (AMBP), ankle brachial index (ABI) and left ventricular mass index (LVMI) in hypertensive patients. Methods 578 hypertensive inpatients were reviewed. Results The general clinical dataof selected patients, their ABI, LVMI were not different significantly between male and female. The correlation analysis showed that LVMI was positively correlated with the 24-hour average systolic (r=0.245, P=0.000) or diastolic (r=0.158, P=0.000) blood pressure, whereas negatively correlated with percent of systolic (r=-0.104, P=0.012) or diastolic (r=-0.132, P=0.001) blood pressure declining at night. No significant correlation was found between LVMI and BMI. Multiple regression analysis revealed that LVMI was significant independently positive correlated with 24-hour average systolic blood pressure (P=0.000). Conclusion LVMI does not correlate with ABI, but independent positive related with 24-hour average systolic blood pressure.

ABSTRACT

Objective To investigate the levels of serum retinol-binding protein 4 (RBP4) and high sensitive C reactive protein (hs-CRP) in type 2 diabetic mellitus (T2DM) patients with macrovascular complications. Methods All of 115 subjects were divided into 3 groups: normal control group (35subjects), T2DM patients with macrovascular complications group (40 subjects) and simple T2DM patients group (40 subjects). Serum RBP4 and hs-CRP was detected and fasting blood glucose(FBG), glycosylated hemoglobin A1c (HbA1c), triacylglycerol (TG), total cholesterol (TC), high density lipopretein cholesferel (HDL-C), low density lipoprotein cholesferol(LDL-C) and fasting insulin(FINS) were measured. Body mass index (BMI) and HOMA-IR was calculated. The correlation of RBP4 and other factors were analyzed.Results The concentrations of RBP4 and hs-CRP were significantly increased in T2DM patients with macrovascular complications group and simple T2DM patients group compared with those in normal control group [hs-CRP:(9.12±4.21),(2.01±1.96), (0.98±0.36)mg/L; RBP4:(30.70 ± 5.45), (20.02±5.32),(12.02±3.45)mg/L] (P<0.01). Also,the concentrations of RBP4 and hs-CRP were significantly increased in T2DM patients with macrovascular complications group compared with those in simple T2DM patients group (P<0.01). Univariate analysis showed that serum RBP4 was positively associated with LDL-C,BMI,FBG,hs-CRP,FINS,HOMA-IR (r=0.325, 0.597, 0.323, 0.571, 0.275, 0.463,P<0.05 or <0.01).Conclusions The concentrations of RBP4 and hs-CRP are significantly higher in T2DM patients. The changes of RBP4 and hs-CRP are closely related to the occurrence and development of diabetic macrovascular complications.

Objective To investigate the involvement of posterior auricular muscle (PAM) and the effect of botulinum toxin type A (BTX-A) injection into PAM in patients with hemifacial spasm (HFS)complicated by auricular symptoms.Methods Sixty-three consecutive HFS patients with auricular symptoms such as tinnitus or murmur,"ticking" or a "clicking" sound and discomfort on the same side,referred to our department between July,2009 and January,2010,were enrolled,and the diagnosis of idiopathic HFS was clinically made.The patients were largely randomized into two groups according to the order of referral.One was regular group including 33 cases whose injection sites were routinely at the frontal,orbicularis oculi,zygomaticus and buccinator muscles while another was PAM group including 30 cases,in which 4 units of BTX-A was additionally injected to the PAM.Before and after injection,the test of blink reflex was performed and lateral spread of blink reflex to orbicularis oris(OO)and PAM,I.e.Abnormal muscle response(AMR),were recorded,and the peak-peak amplitude of AMR was measured.The patients were followed up clinically and electrophysiologically at least 4 weeks((29.5±2.5)days) later.Results(1)The patients reported that their auricular symptoms subsided after injection in both groups.The remission rate was 45.5%(15/33)in the regular group and 76.7%(23/30)in the PAM group,respectively,with a higher rate in the PAM group(x2=6.40,P=0.011).(2)In both groups the AMR amplitude decreased significantly after injection.In the regular group,the OO amplitudes (μV) before and after injection were 304.0±30.3 and 129.3±9.6(t =5.820,P =0.000),and PAM amplitudes,298.0±33.3 and 184.7±20.2(t=2.818,P=0.014),respectively.In the PAM group,OO amplitudes were 405.3±66.7 and 116.0±10.0(t=4.214,P=0.001),PAM amplitudes,390.0±53.6 and 72.0±9.7(t=6.011,P=0.000),respectively.(3)The decrease of PAM amplitudes in the PAM group was more significant compared with those in the regular group (t=4.237,P=0.001).Conclusions In HFS patients with auricular symptoms,the electrophysiological studies are helpful for the guidance of treatment;and the auricular symptoms could be better improved after BTX-A injection into PAM in addition to those regular injection sites.

ABSTRACT

Objective To study the postoperative recovery in patients undergoing coronary artery bypass grafting (CABG)with a history of cerebral infarction.Methods From January 2007 to December 2007,112 patients undergoing elective off-pump coronary artery bypass grafting(OPCABG)with a history of cerebral infarction were studied retrospectively.Each of the 112 patients was matched with 1 control patient who had no cerebral infarction history and were undergoing an elective OPCABG either immediately before or immediately after the study patient,in most cases by the same surgeons.Preoperative characteristics,anesthesia time,awakening time,extubation time,ICU stay,hospital stay,reintubation,hospital mortality,postoperative confusion and stroke were compared in the two groups.Results There were no significant differences between the study and control Patients in the most preoperative characteristics,only the incidence of hypertension and diabetes mellitus were higher than those in control group,P<0.05(78 of 112,69.6% versus 61 of 112,54.5%;52 of 112,46.4% versus 26 of 112,23.2%).The study group took longer to awaken,extubate and stay in ICU and hospital than the control group,P<0.01[(6.4±4.0)h versus(4.6±2.7)h,(19.6±9.7)h versus(16.8±5.5)h,(27.3±16.8)h versus(22.1±10.6)h,(23.4±10.0)d versus(19.5±5.6)]d.The incidence of confusion,stroke and reintubation after operation among the study group was higher than those in control group,P<0.05(17 of 112,15.2% versus 4 of 112,6.3%;8 of 112,7.1% versus 1 of 112,0.9%;8 of 112,7.1% versus 1 of 112,0.9%),RR and 95% CI were 4.83(1.57~14.86)、8.54(1.05~69.45)and 8.54(1.05~69.45).There were no significant differences between the study and control patients in the anesthesia time and hospital mortality.Stroke after the operations was found in 8 of 112 study patients and included cerebral infarction in 6 and transient ischemic attack(TIA)in 2.The 8 patients included new stroke in 7 and worsening of old stroke in 1 without new abnomalities on head computed tomography.1 of 8 patients had early stroke(≤24 hours after operation)and others had late stroke(>24 hours).Conclusion The patients with previous cerebral infarction undergoing off-pump coronary artery bypass grafting took longer to awaken,extubate,stay in ICU and hospital.These patients were more likely to have reintubation,confusion and stroke after operation than those patients with no cerebral infarction history.

ABSTRACT

Objective To investigate the value and limitations of ultrasound determination-evaluated brachial artery endothelial function in elderly diabetic patients. Methods High-resolution two-dimensional ultrasound was used to determine brachial artery(BA) flow-mediated vasodilation(FMD) during reactive hyperemia. Endothelial function was evaluated by FMD in 67 elderly patients with type 2 diabetes. Results In diabetes versus normal control group,the BA diameter and flow velocity showed no significant difference (P>0.05) at basal state,but showed significant decreases (P<0.05) after reactive hyperemia. Single-factor correlation analysis showed that FMD was in negative correlation with disease course, TG, ISI and age (r=-0.2357,-0.2215 and -0.3256, -0.2415,(all P<0.05~0.01),and showed no correlation of FMD with BMI, TC, FBG, HbA1c, FIns. Conclusions FMD has a value in evaluating the flow-mediated endothelial dysfunction in older T2DM patients, while our analysis of the results should consider the patient's age, gender, race, disease course, blood lipids and other factors.

ABSTRACT

Objective To investigate the levels of serum retinol-binding protein 4 (RBP4 )and related factors in type 2 diabetic patients. Methods Eighty type 2 diabetic and patients 30 non-diabetic subjects were recruited into obese-diabetic group [body mass index (BMI) 1525 kg/m~2],normal-weighted diabetic group(BMI < 25 kg/m~2)and control group(BMI < 25 kg/m~2). Serum adiponectin(APN), RBP4 and hemoglobin A_1c (HbA_1c)triacylglycerol (TG),total cholesterol (TC).high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C)and were measured on fasting samples. BMI, waist/hips girth ratio (WHR) and insulin resistance index (HOMA-IR) were calculated. The correlation between RBP4 and other factors was analyzed. Results The concentration of RBP4 was significantly increased in obese-diabetic group and normal-weighted diabetic group compared with that in control group [ (30.02 ± 5.32), (20.10 ± 5.45), (12.02 ± 3.45) mg/L] (P < 0.01). The concentration of RBP4 was higher in obese-diabetic group than that in normalweighted diabetic group (P < 0.01). Univariate analysis showed serum RBP4 was positively associated with TG,BMI,FBG, WHR,FINS,HOMA-IR and negatively associated with APN (r = 0.225, 0.697, 0.323,0.557, 0.272, 0.461, -0.398). Conclusions The concentration of RBP4 is significantly higher in type 2 diabetic patients compared with that in normal subjects. RBP4 possibly plays an important role in the insulin resistance and the occurrence and development of type 2 diabetes.

ABSTRACT

0.05)Conclusion There are some free cancer cells in the prepheral blood of some patients with gastric cancer before operation. Pulling and stimulating tumor in the operation may increase cancer cell dissemination.Simple ligation of peripheral veins around stomach could not completely prevent cancer cell dissemination in the peripheral blood.
