The present study aimed to explore the neuroprotective effect and possible mechanisms of rhGLP-1 (7–36) against transient ischemia/reperfusion injuries induced by middle cerebral artery occlusion (MCAO) in type 2 diabetic rats. First, diabetic rats were established by a combination of a high-fat diet and low-dose streptozotocin (STZ) (30 mg/kg, intraperitoneally). Second, they were subjected to MCAO for 2 h, then treated with rhGLP-1 (7–36) (10, 20, 40 µg/kg i.p.) at the same time of reperfusion. In the following 3 days, they were injected with rhGLP-1 (7–36) at the same dose and route for three times each day. After 72 h, hypoglycemic effects were assessed by blood glucose changes, and neuroprotective effects were evaluated by neurological deficits, infarct volume and histomorphology. Mechanisms were investigated by detecting the distribution and expression of the nuclear factor erythroid-derived factor 2 related factor 2 (Nrf2) in ischemic brain tissue, the levels of phospho-PI3 kinase (PI3K)/PI3K ratio and heme-oxygenase-1 (HO-l), as well as the activities of superoxide dismutase (SOD) and the contents of malondialdehyde (MDA). Our results showed that rhGLP-1 (7–36) significantly reduced blood glucose and infarction volume, alleviated neurological deficits, enhanced the density of surviving neurons and vascular proliferation. The nuclear positive cells ratio and expression of Nrf2, the levels of P-PI3K/PI3K ratio and HO-l increased, the activities of SOD increased and the contents of MDA decreased. The current results indicated the protective effect of rhGLP-1 (7–36) in diabetic rats following MCAO/R that may be concerned with reducing blood glucose, up-regulating expression of Nrf2/HO-1 and increasing the activities of SOD.

The pharmacy of Y anqing Winter （Paralympic）Olympic Village Polyclinic of 2022 Beijing Winter （Paralympic） Olympic Games will be comprehensively managed from five aspects of man ，machine，material，method and environment by adopting the 4M1E management method of quality management tool . In terms of man ，constantly enhanced training and daily health monitoring have been insisted ；in terms of machine ，drug information entry and drug information management have been improved and maintained ；in terms of drugs ，on the basis of drug management ，the management of drugs banned by the World Anti -Doping Agency，class Ⅱ psychotropic drugs and narcotic drugs have been strengthened ；in terms of regulations and environment ，strict pharmacy workflow and management system have been established ，and epidemic prevention closed -loop management requirements have been strictly implemented . From the pre -opening of Yanqing Winter （Paralympic）Olympic Village on January 23，2022 to the official closing of the Village on March 16，2022，the clinic pharmacy dispensed a total of 156 prescriptions（105 prescriptions during the Winter Olympic Games ，51 prescriptions during the Winter Paralympic Games ），including 18 prescriptions from the National （Regional） Olympic Committee and the National （Regional） Paralympic Games team doctors ，2 prescriptions containing stimulants that do not need to be exempted from treatment，1 prescription for narcotics ，and 37 prescriptions for athletes（23.7%）. Ibuprofen tablets ，Diclofenac diethylamine emulsion，Loratadine tablets and other drugs are widely used . The application of 4M1E management method enables the clinic pharmacy to provide perfect and high -quality pharmaceutical services for large -scale events while doing well in epidemic prevention and control .

OBJECTIVE：To investigate the clini cal features of thrombocytopenia induced by antidepressants ，and to provide reference for the rational use of clinical drugs. METHODS ：Retrieved from CNKI ，Wanfang database ，VIP，PubMed and Web of Science，during Jan. 1st in 1985 to Aug. 31st in 2020，case reports about antidepressants-induced thrombocytopenia was collected and analyzed descriptively in terms of demographic characteristics ，medication，clinical manifestations ，treatment and outcome. RESULTS：A total of 17 literatures were retrieved ，and 19 patients were included ，involving 10 male and 9 female，aged from 5 to 95 years old ，with an average of （48±24）years old. Nine kinds of drugs were involved ，including 4 cases of escitalopram ，3 cases of citalopram ，3 cases of fluoxetine ，3 cases of mirtazapine ，2 cases of amitriptyline ，1 case of sertraline ，1 case of paroxetine，1 case of mianserin and 1 case of imipramine. There were 9 cases of single drug and 10 cases of drug combination. All 19 patients suffered from thrombocytopenia at 3 d-10 years after medication ，14 of them had hemorrhage tendency. Main clinical manifestations included mucocutaneous hemorrhage ，gingival bleeding ，black stool ，hematochezia，vaginal bleeding ，ocular hemorrhage，alveolar hemorrhage. No bleeding was found in 5 cases. After drug withdrawal/changing drugs and other symptomatic treatment， platelet count of 19 patients recovered to normal ， and bleeding symptoms disappeared. CONCLUSIONS ： Thrombocytopenia caused by antidepressants has no obvious clinical features and is not easy to be found ，but it may lead to severe； bleeding symptoms if it is not found in time. The changes of platelet count should be closely monitored in clinical application of such drugs to ensure the safety of drug use.
