ABSTRACT
Objective To investigate the status of medication adherence of secondary prevention after acute ischemic stroke and influence on prognosis in Qingdao area , including antithrombotic drugs , lipid-lowering drugs , antihypertensive drugs and glucose-lowering drugs , to provide the basis for making medical policy.Methods We examined patients with acute cerebral infarction and transient ischemic attack in the Department of Neurology of Affiliated Hospital of Qingdao University from December 2014 to January 2016.Patients′medication status and recurrence of stroke events were registered by using telephone and clinic follow-up within six months after the patients discharged from hospital .The standard of good and bad drug adherence was as follows:good adherence was defined as proportion of days covered ( PDC) ≥80%, bad adherence was defined as PDC <80%.SPSS 19.0 statistical software was used to analyze the influence factors of medication adherence and the influence of medication adherence on prognosis .Results Finally, 444 cases (88.62%) were analyzed.A total of 352 cases (79.28%) had high medication adherence at six months after discharging from hospital .The following factors can improve the adherence of drug treatment:history of diabetes (108 cases (30.68%) in good medication adherence group , 16 cases (17.39%) in poor medication adherence group,χ2 =6.401, P=0.011), having employee health insurance (186 cases (52.84%) in good medication adherence group , 33 cases (35.87%) in poor medication adherence group ,χ2 =8.405, P=0.004), endovascular stent implantation (29 cases(8.24%) in good medication adherence group, 0 case in poor medication adherence group ,χ2 =8.109, P=0.004), staying in hospital more than 10 days ( 230 cases ( 65.34%) in good medication adherence group , 49 cases ( 53.26%) in poor medication adherence group ,χ2 =4.558, P=0.033).Six months later , the modified Rankin Scale ( mRS) score of poor medication adherence group was significantly higher than that in good adherence group ( mRS score≥3,50 cases (14.20%) in good medication adherence group , 22 cases (23.91%) in poor medication adherence group,χ2 =5.060, P=0.024) .After six months, a total of 13 cases had recurrent cerebral infarction, with two cases ( 0.57%) in good adherence group , 11 cases ( 11.96%) in poor adherence group.High medication adherence was an independent protective factor of recurrent stroke ( OR=0.042, 95%CI 0.008 -0.210, P<0.01 ) .At one, three, six months after discharging from hospital , the medication adherence of antihypertensive and glucose-lowering drugs was better than that of antiplatelet agents and lipid-lowering drugs (all P<0.05).Conclusions The persistence and adherence to secondary preventive medication in ischemic stroke patients was generally well at 6th month after discharging from hospital.History of diabetes , having employee health insurance , stent implantation and longer hospital stay are the influencing factors to high medication adherence .High medication adherence is an independent protective factor for ischemic stroke recurrence .The medication adherence of antihypertensive and glucose-lowering drugs is better than that of antithrombotic drugs and lipid-lowering drugs.
ABSTRACT
Objective To compare the use of solifenacin and trospium in treatment of overactive bladder (OAB).Methods This prospective study was conducted on patients diagnosed with OAB who presenting to the Department of urology,Changzhou No.3 People's Hospital between March 2015 and May 2016.Patients were randomized into 2 groups.Group A (n =40) received 5 mg solifenacin once daily,while Group B (n =39) received 20 mg trospium twice daily.All the patients' OAB symptom scores (OABSS) in weeks 0,4,and 12 were recorded.In addition,side effects of the drugs were evaluated.Results Average OABSS was determined as:9.3 ± 2.6 (Group A) and 10.2±1.9 (Group B) at week0;2.5±1.3 (GroupA) and 2.7±1.4 (Group B) at week4;and 1.4±0.5 (Group A) and 1.3 ± 0.6 (Group B) at week 12.In addition,no statistically significant difference was found between the scores (P =0.084,P =0.512 and P =0.423).The discontinuation rate of medication due to its side effects was 0 (0％) for Group A,and 5 (12.8％) for Group B.Intragroup changes in the scores 0 weeks-4 weeks,0 weeks-12 weeks and 4 weeks-12 weeks values was statistically significant in both groups (P =0.000).Conclusion No significant difference was found between the OABSS of these 2 drugs.However,discontinuation of drugs due to side effects was more frequent in trospium.
ABSTRACT
Objective To observe the therapeutic effect of suspending-needle therapy combined with modified Zhengan Xifeng Decoction for the treatment of primary facial spasm,and to explore an effective traditional Chinese medicine therapy for primary facial spasm.Methods A total of 65 qualified patients were randomly divided into trial group (33 cases) and control group(32 cases),which was treated with suspending-needle therapy combined with modified Zhengan Xifeng Decoction,Carbamazepine tablets respectively.Twenty-eight days constituted one course of treatment.After treatment for one course,therapeutic efficacy of the two groups was evaluated,and the degree of facial spasm was assessed.Results (1) After one course of treatment,the markedly-effective rate of the trial group was 84.8％,and that of the control group was 62.5％,the difference being significant(P ＜ 0.05).(2) After treatment,the degree of facial spasm in the two groups was much improved as compared with that of the control group (P ＜ 0.05 or P ＜ 0.01),and the improvement in the trial group was superior to that in the control group (P ＜ 0.01).Conclusion Suspending-needle therapy combined with modified Zhengan Xifeng Decoction has better effect on relieving facial spasm of the primary facial spasm patients than Carbamazepine tablets.
ABSTRACT
Objective To detect the immune effect of FbaAmAb2 against the surface protein of group A Straptococcus (GAS),and explore the pathogenesis and therapy of GAS infections.Methods By subclonal and bacterial ELISA,the positive hybridoma cells were screened that can produce better titers of FbaAmAb2 against GAS-surface FbaA protein,and were injected into the peritoneal cavities of BALB/c mice to produce ascites.The collected ascites were performed to dilute,as follows,original ascite,1:2,1:4,1:8,and 1:16 to test tube agglutination.Based on the results,we selected appropriate dilution to passively immunize mice,and then challenged the mice with GAS,evaluating FbaAmAb2 neutralizing ability with GAS in mice by the survival rate of the immunized mice.Whether FbaAmAb2 could inhibit the binding of factor H to GAS was confirmed by the invasive inhibition assay.Results The IgG titer of bacteria solution ELISA is 1:160 and the titer of tube agglutination is 1∶8.The protect rates of FbaAmAb2 on preventing mice with GAS infections are as follows:66.67％ in original ascite and 1:2 diluted groups,and 50％ in 1:4 diluted group.Mice in each experimental group were evoked significantly protective immune responses compared with the PBS control by SPSS analysis.FbaAmAb2 can competitively inhibit factor H binding to the surface proteins FbaA of GAS,which decreased the entry of GAS into the cytoplasm of human epithelial cells through the binding of factor H.Conclusion FbaAmAb2 is promising to be used in emergent prevention or the clinical therapy for GAS infection and it is promising starting points for pharmacologic targeting and further development of new therapeutic agents for GAS.
ABSTRACT
Objective To study the bystander effects and associated mechanisms through irradiated conditioned medium(1CM). Methods Natural kilhr(NK) cells were obtained from peripheral blood samples. ICM irradiated with different doses of 60Coγ-rays was used for culturing K562 cell strain. The degree of injury of K562cells by activated NK cells was observed, as well as the apoptosis frequency of K562 cell was investigated. Results Severe injury was induced in K562 cells cultured in ICM than the control (sham-irradiated) as shown by increased sensitivity to NK cells (P < 0.05). The apoptosis frequency of K562 cell was increased significantly compared with the control cells (P < 0.05). Conclusions The bystander effect induced by irradiation is existent. ICM can trigger the bystander effect on K562 cell strains.

Objective To study the effects of Ginkgo biloba extract (GBE) on free radical metabolism of different fiber types of quadriceps in exercised rats and its mechanism. Method Increasing load exercised rat model was selected. The test rats were orally given GBE aqueous suspension (100 mg/ kg?d), and the controls with water. The levels of malondialdehyde (MDA) and the activities of total superoxide dismutase (T-SOD), glutathione peroxidase (GSH-Px) of red muscle, white muscle and whole quadriceps of exercised rats were examined before exhaustive exercise, at instant,24h and 48h after strenuous exhaustive exercise. Results Compared with the controls,MDA contents were 49.69% higher in white muscle (P
ABSTRACT
Objective To observe endothelial cells secreting and expressing nitric oxide by using red laser irradiation ( RLI) on cultured endothelial cells. Methods Cultured endothelial cells were irradiated with a red laser for 10, 20, and 30 minutes, respectively, and the concentration of nitric oxide in the cell supernatant was measured after 15 min,30 min.1 h,3 h and 6 h. In addition, the expression of inducible nitric oxide synthetase (iNOS) and endotlielial nitric oxide synthetase (eNOS) was measured through immunohistochemical staining. Results Compared with that in the control group, the expression of eNOS by the endothelial cells and the concentration of NO were stimulated by 2 mW RLI for 10 min, 20 min and 30 min, and reached a peak at 1 h, then declined gradually. The expression of iNOS, however, showed no significant difference. Conclusion RLI can increase NO concentrations in endothelial cells by stimulating the expression of eNOS rather than iNOS.
