Moyamoya disease is a chronic progressive cerebrovascular disease. It got its nickname, the moyamoya disease, because the image of abnormal blood vascular net at the skull base in the encephaloangiography of such patients is very similar to smog. The moyamoya disease can be divided into two types: ischemic and hemorrhagic according to its clinical manifestations and imaging characteristics. In the ischemic type of moyamoya disease, when the blood vascular lumens are not narrow enough to completely block the blood flow, the chief manifestation is the cerebral blood circulation insufficiency; when the salvage is not in time, the disease will further progress to develop vascular obstruction or thrombosis, resulting in cerebral infarction, finally hemiplegia, aphasia, etc. irreversible symptoms and signs occur. In the primary hospital, the first choice for treatment of acute cerebral infarction (ACI) is drug thrombolysis. However, the main treatment for moyamoya disease with ACI is chiefly revascularization. This article reported a patient with moyamoya disease and ACI successfully treated by intravenous reteplase for thrombolysis in People's Hospital of Pucheng County.

Objective:To analyze the use status of antibiotics and the resistance of clinic isolate bacteria against the commonly used antibiotics before and after the intervention. Methods:Using the information retrieval systems, the consumption of antibiotics in the inpatients during the 1st quarter of 2012(before the intervention) and the same period of 2013(after the intervention) was com-pared. According to the defined daily dose ( DDDs) , the antibiotics were ranked, and the resistance rate against the commonly used antibiotics was analyzed. Results:Compared with the top ten before the intervention, the top ten after the intervention was changed sig-nificantly, however, cephalosporins was still the main species. After the intervention, the overall decline in DDDs was significant, the separation rate and distribution of bacteria remained stable. ESBLs enzyme production rate of Enterobacteriaceae Escherichia coli was re-duced by 7. 61%, and that of Klebsiella pneumoniae was reduced by 1. 34%, and the resistance rate against the commonly used antibi-otics was in an overall downward trend. The resistance rate of Gram-positive staphylococci against the commonly used antibiotics was de-creased, while that of Gram-positive enterococci showed notable difference. Conclusion:The DDDs of antibiotics and bacterial resist-ance rate are in an overall downward trend in our hospital after the intervention;however, there is still exception. Therefore, the clini-cal antimicrobial susceptibility tests should be performed as soon as possible to help the choice of antibiotics.

Chinese Journal of Primary Medicine and Pharmacy 2022;29(11):1601-1605
Objective:To investigate the effect of dexmedetomidine combined with butorphanol on perioperative analgesia in patients subjected to cardiac surgery.Methods:Sixty-three patients who underwent elective cardiac surgery in Weihai Central Hospital from June 2019 to August 2020 were included in this study. They were divided into propofol + sufentanil group ( n = 21), dexmedetomidine + sufentanil group ( n = 23) and dexmedetomidine + butorphanol group ( n = 19) according to different analgesic methods. Postoperative analgesic satisfaction, Visual Analogue Scale score, hemodynamic changes (heart rate, respiratory rate, systolic blood pressure, diastolic blood pressure) and adverse reactions were compared among the three groups. Results:The satisfaction rate of postoperative analgesia in the dexmedetomidine + butorphanol group was 94.7% (18/19), which was significantly higher than 61.9% (13/21) in the propofol + sufentanil group and 60.8% (14/23) in the dexmedetomidine + sufentanil group ( χ2 = 6.16, 6.57, both P < 0.05). At 4, 12, 24 and 48 hours after tracheal extubation, Visual Analogue Scale score in the dexmedetomidine + butorphanol group were significantly lower than that in the propofol + sufentanil group and dexmedetomidine + sufentanil group (both P < 0.05). At the time of tracheal extubation and at 5 minutes after tracheal extubation, heart rate, respiratory rate, systolic blood pressure and diastolic blood pressure in the dexmedetomidine+butorphanol group were significantly lower than those in the propofol + sufentanil group and dexmedetomidine + sufentanil group (both P < 0.05). The incidence of adverse reactions in the dexmedetomidine + butorphanol group was 10.5% (2/19), which was significantly lower than 23.8% (5/21) in the propofol + sufentanil group and 30.43% (7/23) in the dexmedetomidine + sufentanil group [30.4% (7/23), χ2=21.94, P < 0.001]. Conclusion:Dexmedetomidine combined with butorphanol in cardiac surgery can not only stabilize postoperative blood pressure and heart rate, but also lower the degree of pain and is highly safe.
