Objective To investigate the inhibition effects of simvastatin on proliferation and migration of cultured porcine coronary vascular smooth muscle cells (SMCs) induced by oxidized lower density lipoprotein (OX-LDL). Methods Porcine coronary SMCs were incubated with serum-free medium containing different concentrations of simvastatin. Infiltration of ~3H-TdR into SMC DNA was measured as an index of cell proliferation. Simvastatin's effect on migration was tested with Sarkar's technique. Results Different concentrations of simvastatin (10~(-8)-10~(-5) mol/L) caused a decrease in ~3H-TdR infiltration in porcine coronary SMC. The migration number of porcine coronary SMCs also decreased proportional to the simvastatin concentration. Conclusion Simvastatin can inhibit the proliferation and migration of porcine coronary SMCs stimulated by OX-LDL in a dose-dependent manner.

Objective To investigate the changes of serum angiopoietin-like protein 3 (Angptl3) and adiponectin levels in patients with metabolic syndrome (MS) in order to understand their association with the MS. Methods Serum Angptl3 and adiponectin levels were measured by sandwich ELISA in a group of 111 patients with MS and 152 normal controls. Results Serum adiponectin was lower in the MS patients than in the control subjects [4.22(1.01-23.29) μg/mL vs. 5.41(0.97-22.27) μg/mL, P＜0.05]. With regard to serum Angptl3, there was no significant difference between the 2 groups(P＞0.05). Serum adiponectin was correlated to Angptl3 and high density lipoprotein-cholesterol (HDL-C)(P＜0.001) and negatively correlated to body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), triglyceride (TG), fasting plasma glucose (FBG), fasting insulin (FINS) and homeostatic model assessment method-insulin resistance (HOMA-IR) (P＜0.001). Serum Angptl3 was positively correlated with adiponectin (P＜0.001). Serum adiponectin was found to be independently positive determinant for Angptl3 concentrations (b′=0.256, P＜0.001). Adiponectin was inversely correlated with TG and HOMA-IR (b′=-0.234, -0.145, P＜0.001). Conclusion Adiponectin is decreased in MS patients and may be correlated to Angptl3.

OBJECTIVE:To evaluate the effects of clinical pharmacists participating in clinical pathway management for chron-ic heart failure(CHF). METHODS:A total of 107 CHF adult inpatients in Linyi People's Hospital during Jan. 2014-Oct. 2015 were divided into control group(56 cases,3 withdrawal,53 in total)and trial group(58 cases,4 withdrawal,54 in total)accord-ing to random number table. Control group received routine clinical pathway management method of CHF;trial group received clin-ical pathway management with the participation of clinical pharmacists. Clinical efficacy,the utilization of heart failure drugs,eco-nomic indexes,medication compliance after discharge,re-hospitalization rate due to heart failure were compared between 2 groups. RESULTS:Total response rate of trial group was significantly higher than control group,with statistical significance(P<0.05). The utilization rate of ACEI/ARB,β-receptor blocker,target dose rate of ACEI/ARB in trial group were significantly higher than control group,with statistical significance(P<0.05);target dose rate of β-receptor blocker was higher than control group,without statistical significance(P>0.05). Hospitalization time,drug cost,total hospitalization cost and drug ratio of trial group were short-er or lower than control group,without statistical significance(P>0.05). One month after discharge,the proportion of medication compliance in trial group was significantly higher than control group,with statistical significance(P<0.05);re-hospitalization rate was lower than control group,without statistical significance(P>0.05). Three months after discharge,the proportion of medica-tion compliance in trial group was higher than control group,while re-hospitalization rate was lower than control group,with statis-tical significance(P<0.05). CONCIUSIONS:The participation of clinical pharmacists in clinical pathway management of CHF can significantly improve the utilization rate of recommended drugs by guideline,clinical efficacy and medication compliance,and reduce re-hospitalization rate.

Objective To investigate the prevalence and clinical features of fulminant type 1 diabetes.Methods Using data retrieved from Second Xiangya Hospital of Central South University,all patients diagnosed with type 1 diabetes from Jan.1,2001 to Dec.31,2007 were identified.The patients were divided into fulminant type 1 diabetes (F1D) group,typical type 1 diabetes (T1A) group,and idiopathic type 1 diabetes(T1B) group.Their clinical features were compared.Results Eight patients (9.1%) fulfilled the criteria for fulminant type 1 diabetes among 87 newly diagnosed type 1 diabetes,and the percentage of fulminant type 1 diabetes reached 14.0% among type 1 diabetic patients with age of onset of 18 years or older.Patients of F1D group had a markedly higher plasma glucose concentration compared with patients of T1A group and T1B group(P=0.004).Serum amylase was higher in F1D group than that in T1A group(P = 0.021).Four (50%) patients were GADA positive,among whom 1 patient was Coxsackie B virus (CVB) IgM positive and 1 patient was Herpes Simplex virus 1 (HSV1) IgM positive.Conclusions Fulminant type 1 diabetes accounts for about 10% of the type 1 diabetes in the Chinese individuals with ketosis-or ketoacidosis-onset.Patients with this subset of diabetes had severe metabolic derangement.Viral infection and autoimmunity may be involved in the pathogenesis of fulminant type 1 diabetes.

Objective To evaluate the effectiveness of anticoagulation management by physician-clinical pharmacist team for patients with valvular atrial fibrillation. Methods One hundred and seventy two patients with valvular atrial fibrillation received warfarin therapy for anticoagulation during hospitalization in Linyi People′s Hospital from January 2014 to December 2016, the patients continued to receive warfarin therapy for>6 months after discharge. The patients were randomly assigned in two groups:the anticoagulation management was given by physician-clinical pharmacist team in 87 cases (trial group), while the dosage of wargarin was adjusted in outpatient department by physicians alone in 85 cases (control group). The goal attainment rate of international normalized ratio (INR), the proportion of patients with a stable warfarin dose, knowledge of anticoagulants, belief of medication, medication compliance were compared between two groups. Results There were no significant differences in age, sex, body weight, smoking and drinking habits, valvular disease type, comorbidities; and the initial INR, knowledge of anticoagulants, belief of medication and medication compliance at admission between two groups (all P>0.05). The goal attainment rate of INR (52.17％vs. 41.02％,χ2=8.178, P=0.004), the proportion of patients with a stable dose of warfarin (74.71％ vs. 56.47％,χ2=6.349, P=0.012), the knowledge of anticoagulants (11.03 ± 2.25 vs. 10.08 ± 1.86, t=3.018, P=0.003), the belief of medication[(12.23 ± 2.07) vs. (11.67 ± 1.48), t=2.042, P=0.043], and the medication compliance[(7.36 ± 0.89) vs. (7.04 ± 1.10), t=2.1128, P=0.036] in the trial group were significantly higher than those in control group. Conclusion Anticoagulation management by physician - clinical pharmacist team can improve the management level of anticoagulation and the knowledge of anticoagulans, enhance the medication belief, improve the goal attainment rate of INR and the compliance rate of medication in patients with valvular atrial fibrillation.

BackgroundPost-traumatic stress symptoms （PTSS） is highly prevalent in adolescents who have experienced earthquake， which seriously threatens their physical and mental health， yet there is currently a lack of research on the effects of loneliness， social support and social media use on PTSS among post-earthquake adolescents. ObjectiveTo assess the PTSS among adolescents experiencing MS6.0 Luxian， Sichuan， earthquake on 16 September 2021， and to investigate the effects of loneliness， social support and social media use on PTSS， so as to provide references for the intervention of PTSS among post-earthquake adolescents. MethodsOn November 12， 2021， simple random sampling technique was used to select 2 522 post-earthquake adolescents in Luxian county of Luzhou city in Sichuan province. All subjects were assessed using Post-Traumatic Stress Disorder Checklist for DSM-5 （PCL-5）， Multidimensional Scale of Perceived Social Support （MSPSS）， Short-form UCLA Loneliness Scale （ULS-3） and Social Media Use Scale （SM-10）. Binary Logistic regression was used to determine the factors influencing PTSS among post-earthquake adolescents. ResultsPTSS was detected in 91 （3.61%） adolescents. Binary Logistic regression revealed that perceived social support from family members （OR=0.926， 95% CI： 0.879~0.976） was a protective factor for PTSS among post-earthquake adolescents. Lack of companionship （OR=1.764， 95% CI： 1.141~2.727）， feeling isolated （OR=2.037， 95% CI： 1.282~3.236）， and viewing negative emotional response of disaster victims through social media （OR=1.615， 95% CI： 1.291~2.020） were risk factors for PTSS among post-earthquake adolescents. ConclusionLack of companionship， feeling isolated， and viewing negative emotional response of disaster victims through social media pose a negative impact on PTSS among post-earthquake adolescents， while perceived social support from family members exert a positive impact on PTSS among post-earthquake adolescents. ［Funded by Humanity and Social Science Youth foundation of Ministry of Education of China （number， 22YJC190019）； Natural Science Foundation of Sichuan Province （number， 2023NSFSC1486）］
