ABSTRACT
OBJECTIVE：To investigate the situ ation and characteristics of ADR reports in the elderly patients （≥65 years old ） of Sichuan province ，and to provide reference for guaranteeing the safety of drug use. METHODS ：ADR reporting data of elderly patients collected by spontaneous reporting system of Sichuan ADR monitoring center from 2013 to 2019 were collected ，and then analyzed in respects of report types ，reproting institution ，relationship，patienst’age，gender，nationality，drug type ，organ/system invovled. RESULTS & CONCLUSIONS ：In the past seven years ，175 431 cases spontaneous ADR were collected by Sichuan ADR monitoring center ，and the annual proportion of “general”ADR reports decreased from 78.93％ in 2013 to 60.50％ year by year ； the annual proportion of “new general ”and“serious”ADRs increased year by year ，among which that of “new general ”ADR increased more obviously. The main reporting institutions were medical institutions ，accounting for 92.79％-98.87％ of the total annual reports. The enthusiasm of enterprises and individuals to report ADR needed to be improved ；8 031 cases（4.58％）were “positive”relationship，21 283 cases（12.13％）were“likely”，146 117 cases（83.29％）were“possible”. Except that the gender of 272 cases were not reported ，there were 88 176 male cases and 86 983 female cases ；most of them were 65-74 years old （104 962 cases，59.83％）. The reports covered 19 nationalities，among which the re were 166 752 cases（98.72％）of Han nationality. The distribution of ADR related drug categories in elderly patients of Yi ， Tibetan and Qiang nationalities was significantly different from that of Han nationality （P＜0.01）. The top three drug categories in the total frequency were anti-infective drugs （31.10％），traditional Chinese medicine com （18.27％），and central nervous system drugs （9.99％）. The injection route was the most likely to cause ADR （72.12％）. ADR mainly involved s kin and its appendants （21.47％）， gastrointestinal system （19.61％）and central and peripheral nervous system （18.55％）. Aminophylline injection was the only dr ug in the top 10 drugs leading to “new general ”ADR for consecutive 7 years. Cefotaxime sodium for injection ，Ceftriaxone sodium for injection ，Cefoperazone sodium and sulbactam sodium for injection were the top 10 drugs causing “severe”ADR in consecutive 7 years，which should be paid more attention in clinic.
ABSTRACT
OBJECTIVE： To explore the role of clinical pharmacists in medication therapy management （MTM）. METHODS： Referring to the practice model of MTM in the United States， taking a noninfectious chronic disease （obesity diabetes mellitus） patient as an example， clinical pharmacists of endocrinology specialty carried out MTM according to five processes， such as patient information collection， medication therapy review， the formulation of medication-related action plan （MRP）， interventions related to direct communication with physicians or advising patients to consult relevant medical service personnel， record and follow-up. RESULTS： The information of patients collected by clinical pharmacists included past medical history， family history， allergy history and medication history， etc. It was the top priority MRP for this patient to identify inappropriate hypoglycemic drug therapy， obesity-induced obstructive sleep apnea-hypopnea syndrome and hyperlipidemia. For obesity patients with type 2 diabetes mellitus， clinical pharmacists recommend that patients changed insulin drugs to non-insulin drugs， and liraglutide was recommended. In view of the poor control of blood lipid level， fenofibrate was recommended for patients on the basis of oral administration of simvastatin. The patient’s attending physician agreed with the above suggestion and adjusted the prescription. Clinical pharmacists provided medication education for the patients about the importance of each drug， control of total energy intake， balanced diet and physical exercise. The follow-up results after 6 months showed that blood glucose （fasting blood glucose 5-7 mmol/L， postprandial blood glucose 8-10 mmol/L） and blood lipid （total cholesterol 4.80 mmol/L， triglyceride 1.60 mmol/L， low density lipoprotein 3.05 mmol/L） of the patient were effectively controlled and body weight was reduced by 3 kg， but the improvement of lifestyle was poor， mainly due to the nature of his work. Clinical pharmacists once again communicated with him and emphasized the importance of proper physical exercise. The patients agreed to continue the follow-up. CONCLUSIONS： Clinical pharmacists can provide professional consultation and service for patients with chronic diseases by means of MTM service mode， which has certain value for improving medical quality.
ABSTRACT
OBJECTIVE:To investigate the status quo of knowledge-attitude-practice(KAP)of medication in residents,and to explore potential risk factors that may affect medication. METHODS:By approximate random sampling,online(wenjuanxing)and offline method (5 communities of Chengdu city) were used to collect general information (gender, age, monthly income, residence,medical insurance,education level,working condition,occupation)of the residents aged 19 year-old above and conduct KAP investigation during Jul.-Aug. 2017. Multiple linear regression analysis was used to analyze the influence of residents'general information on KAP. RESULTS:A total of 517 online and offline valid questionnaires were obtained, including 200 offline questionnaires were sent out and 184 valid questionnaires were returned with recovery rate of 92％. Average scores of medication knowledge,attitude and practice were (71.4 ± 32.3),(33.7 ± 14.0),(60.7 ± 19.4),which all reached"good"in the evaluation standard of questionnaire results. The results of multiple linear regression showed that elderly and low education level were the significant influential factors of residents'lack of medication knowledge. The male,elderly,low income and low education level were the influential factors of poor drug use behavior. The residents with poor attitudes towards medication were low income and low educated population. CONCLUSIONS:The average risk of residents'medication in China is low,but it is still necessary to strengthen medication education for special people. It is requisite to focus on the elderly,the low education level,the low income population and the male residents.
ABSTRACT
Background The potential protective effect of ischemia postconditiomng for hypoxia has been determined in many tissues and organs.But its mechanism in retina is still lack.Objective The aim of this study was to investigate the protective effect of ischemia postconditioning on retinal ischemia reperfusion injury.Methods Thirty-six health male Wistar rats were randomized into the normal control group,sham group,ischemia reperfusion group and ischemic postconditioning group.Retinal ischemia reperfusion models were induced by elevating the intraocular pressure to 110 mmHg for 60 minutes,and then the ischemic postconditioning was performed right away,1 minute and 10 minutes after ischemia in the rats of the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ group,respectively.Electroretinogram (ERG) was recorded in the rats 7 days after operation,and the rats were sacrificed by excessive anesthesia.Retinal specimens were prepared for the histopathological examination.The retinal thickness and the recovery rates of ERG a,b waves and oscillation potentials (OPs) were compared among the groups using ANOVA of SPSS software.Results One day after experiment,the structure of rat retinas was nearly normal.However,retinal edema and vacuolar degeneration were seen in the rats of the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups primarily in the inner plexiform layer (IPL),inner nuclear layer (INL).The retinal thickness values of the entire layer,IPL and INL were significantly higher in the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups compared with the normal control group (all at P＜0.05).Seven days after experiment,the retinas were thinner in the rats of the ischemia reperfusion group than those of the rats in the sham group,but the retinal thickness values in the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups were significantly increased in comparison with the ischemia reperfusion group (all at P＜0.05).In addition,the recovery rates of ERG a,b,OPs amplitudes were significantly lower in the ischemia reperfusion group and ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups compared with the normal control group (all at P＜0.05).However,the recovery rates of ERG a,b,OPs amplitudes evidently elevated in the ischemic postconditioning Ⅰ,Ⅱ,Ⅲ groups in comparison with the ischemia reperfusion group (all at P＜0.05).Conclusions Ischemia postconditioning can protect the structure and function of retina from ischemia reperfusion injury.Ischemia postconditioning plays the maximal effect immediately to 1 minute after ischemia reperfusion injury in Wistar rat.

ABSTRACT
Objective To explore the clinical features of diabetic macular edema (DME) with optical coherence tomography (OCT) and correlation with visual function. Methods Forty-nine eyes from 40 patients with DME (DME group) and 31 eyes from 31 patients without DME (control group) were examined with OCT,pattern reversal visual evoked potentials (P-VEP),macular perimetry. According to proliferative diabetic retinopathy (PDR), 49 eyes with DME were divided into group A (without PDR, 30eyes) and group B (with PDR, 19 eyes). Results The retinal macular thickness of central fovea in DME group [(299.25±63.87)μm] was more than that in contol group [(204.35 ± 37.94)μm], visual acuity and macular visual field in DME group were significantly different than those in control group, respectively (P ＜ 0.05). The retinal macular thickness of central fovea,visual acuity and visual field were no significant differences between group A and group B (P＞0.05). OCT macular thickness and visual correlation coefficient was -0.437(P＜ 0.05 ); OCT macular thickness and mean defect correlation coefficient was 0.441(P ＜ 0.05). Conclusions OCT can provide a useful tool for monitoring the occurrence and development of DME, can assess the response to treatment. With increasing of the macular retinal thickness, the visual acuity and macular visual field of visual function are more damaged.
ABSTRACT
Objective: To investigate the effects of Ginkgo biloba extract (EGb 761) on the morphology and function of retinal ganglion cells (RGC) in guinea pigs with optic nerve transection. Methods: Seventy-five albino guinea pigs were randomly divided into five groups: normal control group, sham-operated group, untreated group, normal saline group and EGb 761 group. No operation was performed in the normal control group. Optic nerve was merely exposed in the sham-operated group, but transected at 1.0 mm from posterior pole of the eye ball in the untreated, normal saline and EGb 761 groups. Guinea pigs in the EGb 761 group or the normal saline group received daily intraperitoneal injection of EGb 761 (100 mg/kg) or corresponding volume of normal saline from 7 days before experiment to 28 days after experiment. Three guinea pigs in each group were sacrificed for apoptosis assay (TUNEL method) of RGC. Pattern electoretinograms (PERGs) were recorded 14 and 28 days after transection, respectively. At the end of the examination, six guinea pigs were killed for histological examination and RGC count. Results: No TUNEL-positive cells were observed in the normal control, sham-operated and EGb 761 groups, but there were TUNEL-positive cells in the untreated group and the normal saline group. The numbers of RGCs in the untreated and normal saline groups were less than those in the normal control and sham-operated groups at 14 days or 28 days (P0.05) at 14 days or 28 days. The number of RGCs was positive correlated to N(95) amplitude (r=0.859, P=0.001 5). Conclusion: EGb 761 can inhibit the apoptosis of RGCs in guinea pigs after optic nerve transection, thus protect the morphology and function of RGCs.

ABSTRACT
The loci of cDNA sequences for valid diagnosis have been identified through the selection of the genome of SARS coronaries. The gene chips for diagnosing such virus have been developed, based on our own-developed technology for manufacturing and application of gene chips. The diagnoses given by such gene chips were consistent well with the reports of clinical laboratories (94.29%) and the sensitivity reached 10(-2)/ml virus molecules. This method is well suited for the clinical use in SARS coronaries diagnosis.
