Objective To explore the microsurgery methods in patients with early intracranial aneurysm rupture. Methods Sixty-seven patients with early intracranial aneurysm rupture received the emergency microsurgery after releasing cerebrospinal fluid from improved Paine point via pterion craniotomy. Thirty-nine patients received surgery within 1 d after intracranial aneurysm rupture, and the other 28 patients were within 1-3 d. Results The therapeutic effect was evaluated by Glasgow outcome score (GOS) at discharge. Among the 45 patients with Hunt-Hess Ⅰ-Ⅲ grade, cure was in 41 cases, improved in 4 cases. Among the 22 patients with Hunt-HessⅣ-Ⅴgrade, cure was in 6 cases, improved in 6 cases, moderate disability in 4 cases, severe disability in 1 case, and death was in 5 cases. Conclusions The microsurgery of clipping aneurysm directly via pterion approach is still by far the most reliable treatment. And releasing cerebrospinal fluid from improved Paine points can effectively reduce the acute brain swelling of early operation, which will make it an effective adjuvant therapy to emergency microsurgery of clipping aneurysm.

Objective:To compare the clinical efficacy of drug coated balloon (DCB) vs. plain old balloon (POB) on in-stent restenosis (ISR) of femoropopliteal artery occlusive disease of the lower limb. Methods:The clinical data of 91 ISR patients admitted at Shanxi Bethune Hospital from Jul 2016 to Dec 2017 were retrospectively analyzed. The primary patency rates were compared.Results:There were 43 patients treated with drug coated balloons and 48 patients treated with plain old balloons. The surgical procedure was successful in all cases, and the symptoms of lower limb ischemia were significantly improved after surgical procedure. The primary patency rate of patients who were treated by drug coated balloons was significantly higher than by plain old balloons at 12 months after surgery (83.7% vs. 62.5%, P<0.05). Conclusion:The use of drug coated balloons could acquire more satisfactory short-term clinical efficacy for ISR patients of femoropopliteal artery occlusive disease.

Objective:The aim of this study was to explore the relationship between nurses ′ work environment and menopausal symptoms. Methods:A multicenter, cross-sectional study was performed in Beijing, China, distributed to 2 194 registered nurses at 37 hospitals. Using a self-designed questionnaire included individual personal details, and the hospital working environment. Menopausal symptoms were evaluated using a modified Kupperman index (KMI) scoring system.Results:The average natural age at menopause stag was 47.64 years with 63.91% (1 328/2 078) nurses without menopausal symptoms. Logistic analysis showed that menopausal symptoms were co-dependently influenced by the following: to frequently contact with patient bodily fluids during your work ( P=0.037); be intimidated in your work ( P<0.01); to often or occasionally face death at work ( P=0.013 and P=0.002). Nurses suffered more stressful environment with high prevalence of menopausal symptoms. Conclusions:The mid-age nurses with menopausal symptoms were related with work environment. Managers should pay more attention to this problem.

Objective:To understand the spatial distribution of mushroom poisoning in Hunan Province and its influential factors,and to provide the evidence for control of the mushroom poisoning.Methods:The surveillance data for mushroom poisoning cases from 122 counties in Hunan Province in 2015 were collected.Based on geographical information system database,spatial autocorrelation analysis and spatial regression analysis (via OpenGeoDa) was conducted.Results:The incidence of mushroom poisoning in Hunan Province in 2015 was 2.94/100 000.Global Moran's I values was 0.315 (P<0.05).Local spatial autocorrelation analysis indicated that Ningxiang,Xiangtan,Shaoyang,Lingling,Jiahe,and Linwu districts et al were "positive hotspot" regions.Guzhang,Hecheng,Dingcheng,Yueyang districts et al were "negative hotspot" regions.Spatial regression analysis revealed that the reported incidence of mushroom poisoning was positively correlated with the annual average temperate (Z=2.145,P=0.032),the number of health care institutions per capita (Z=2.352,P=0.019),and the number of students enrollment in secondary schools (Z=4.309,P<0.001).It was negatively associated with the number of school staff and workers of secondary schools (Z=-2.626,P=0.009).Conclusion:The spatial distribution of mushroom poisoning cases in Hunan Province in 2015 is highly clustered.Mushroom poisoning cases are more prevalent in the middle and southern regions and less prevalent in the northern areas of the province.The annual average temperate and the number of students enrollment in secondary schools demonstrate a certain positive influence on the distribution of mushroom poisoning in Hunan.

Objective To investigate the mechanism and protective effect of Humanin(HN)on rotenone(Rot)-induced toxic damage for dopamine neurons.Methods The Rot-poisened PC12 cell model was constructed,and the control group,the Rot poisening group,the HN pretreated Rot poisening group,and the HN treatment group were set up.ELISA was used to detect the content of HN inside and outside of Rot-infected cells,CCK-8 assay was used to detect cell viability,and ATP detection kit was used to detect the intracellular ATP content.Dichloro-dihydro-fluorescein diacetate(DCFH-DA)assay was used to detect the level of reactive oxygen species(ROS)in cells.Western blotting was performed to detect the expression level of mitochondrial autophagy regulatory proteins Pink1,Parkin,p62,LC3,mitochondrial biogenesis regulatory protein PGC1α,division/fusion regulatory proteins OPA1,MFN2,DRP1,p-DRP1 and antioxidant stress regulatory proteins Keap1 and Nrf2.HBAD-mcherry-EGFP-LC3 adenovirus transfected cells was used to observed the number of autophagosomes and autophagolysosomes.Results The results showed that the intracellular concentration of HN in PC12 in the Rot poisening group was significantly higher than that in the control group(P<0.05);Compared with the control group,the Rot poisening group had significantly decreased activity of PC12 cells,decreased ATP content and increased production of ROS.After the poisen of Rot in PC12 cells,the expression of Pink1 and p-Parkin,the ratio of LC3Ⅱ/LC3Ⅰ and the expression of p-DRP1 in mitochondrial fusion protein was increased,while the expression of p62,the expression of mitochondrial biogenesis protein PGC1 α,mitochondrial fusion proteins MFN2 and OPA1,and antioxidant stress proteins Keap1 and Nrf2 were decreased(all P<0.05).The number of autophagosomes and autophagolysosomes in PC12 cells in the Rot poisening group was higher than that in the control group(P<0.05),and HN pretreatment(20 μmol/L)could significantly improve the changes mentioned above caused by Rot poisening(P<0.05).Conclusion HN ameliorates Rot-induced toxic damage for dopamine neurons by inhibiting mitophagy and mitochondrial division and promoting mitochondrial biogenesis and fusion,and anti-oxidative stress.

OBJECTIVE:To establish quantitative e valuation system of the prophylactic use of antibiotics in orthopedic type Ⅰ incision surgery ,and to provide reference for evaluating the rational prevention use of antibiotics in this type surgery scientifically. METHODS:Based on the Guidelines of Clinical Use of Antimicrobial Agents (2015 edition),drug instructions ,related guidelines and references ,experts from relevant departments jointly discussed and formulated the evaluation criteria for the rationality of the use of antibiotics in type Ⅰ incision in orthopedic surgery. AHP method was used to assign the weights for various indexes of evaluation criteria ;TOPSIS method was used to retrospectively analyze and evaluate the rationality of 120 cases of type Ⅰ incision surgery from 3 orthopedic departments in Peking University People ’s Hospital during Sept. 1st-30th,2019. RESULTS :Established evaluation system included 4 primary indicators (medication indication ,usage and dosage ,medication timing ,other factors )and 12 secondary indicators. Among the secondary indicators ,indications,drug selection and timing of preoperative administration were the most important (weights were 0.209,0.140,0.117). Among 120 cases,30.83% of drug use were reasonable ,47.50% were basically reasonable and 21.67% were unreasonable. Evaluation results obtained by AHP-TOPSIS were consistent with the actual situation. CONCLUSIONS :The rationality evaluation method of prophylactic use of antibiotics in type Ⅰ incision surgery based on AHP-TOPSIS method can quantitatively evaluate the rationality of drug use by combining multiple indicators. The method is feasible ,operable,and the evaluation results can be quantified ,which has a wide range of application.
