Reperfusion injury occurs after return of spontaneous circulation (ROSC) in patients with cardiac arrest (CA), which leads to multiple organ dysfunction, called post-cardiac arrest syndrome (PCAS). PCAS is closely related to the prognosis of CA patients, and is an independent risk factor of survival. Integrated traditional Chinese and Western medicine diagnosis and treatment is critical for improving prognosis of PCAS. In order to guide and standardize integrated traditional Chinese and Western medicine diagnosis and treatment in PCAS among clinicians, nurses and research personnel in China, the Emergency Medicine Professional Committee of the Chinese Society of Integrated Chinese and Western Medicine has established an expert group to determine 14 clinical issues related to the diagnosis and treatment of PCAS with integrated traditional Chinese and Western medicine through clinical survey. The working group formulates a search strategy for each clinical issue according to the PICO principle. Chinese and English literature were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, and Cochrane Library. The grade of recommendations assessment, development and evaluation (GRADE) were used to form the level of evidence and recommendation. When the literature evidence was insufficient, the recommendations and level of recommendation were formed after expert discussion. Combined with the aspects of generalizability, suitability, and resource utilization, the expert consensus developed 28 recommendations around the 14 aspects of three stages of PCAS, including early circulation, respiratory support and reversible cause relief, mid-term neuroprotection, improvement of coagulation, prevention and treatment of infection, kidney and gastrointestinal protection and blood sugar control, post rehabilitation treatment, providing references for the integrated traditional Chinese and Western medicine of the diagnosis and treatment for PCAS.

Objective To explore the effect of comprehensive intervention on constipation caused by antipsychotic drugs.Methods Ninty patients with antipsychotic drug induced constipation who were admitted to our hospital from June 2012 to October 2013 were enrolled in this investigation and randomly assigned to the comprehensive intervention group(CIG,n=46) and the routine care group(RCG,n=44).The subjects of the RCG received routine diet and medication therapy; and those of CIG received comprehensive intervention of life style,psychological ability,cognition,nursing and traditional chinese medicine(TCM) for 3 months.Constipation symptoms scale and Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) were assessed before and after the intervention.Results CIG showed significant improvement in defecation difficulty,defecation force,defecation duration,frequency,abdominal distension,total symptom score,PAC-QOL,physical discomfort,psycho-social discomfort,anxiety and treatment satisfaction were(2.8±2.1),(2.2±1.6),(2.4±1.3),(2.1±1.7),(1.5±0.9),(14.0±8.1)respectively (t values were 2.629,3.818,2.328,2.593,2.578,2.913,7.499,2.570,5.012,2.249 and 12.259,respectively; all P＜0.05).Conclusion Comprehensive intervention may be an effective therapy against psychiatric drug induced constipation.

Objective To explore the clinical characteristics and risk factors of strokeassociated pneumonia (SAP) in patients with acute cerebral hemorrhage.Methods A total of 375 patients with acute cerebral hemorrhage were selected from the department of neurology and neurosurgery during January 2013 to December 2015 in our hospital.According to the incidence of SAP,they were divided into the observation group (complicated with SAP,n =79) and control group (not complicated with SAP,n =296).Clinical data were collected,and clinical characteristics and related risk factors of SAP complicated with acute cerebral hemorrhage were analyzed.Results Among all the 79 SAP patients in observation group,there were 38 cases with gram-negative bacterial infections,25 cases with gram-positive bacterial infections,16 cases with mixed infections.The SAP incidence in patients with massive hemorrhage was higher than that in patients with nonmasive hemorrhage (x2 =11.301,P＜ 0.01),and was higher in patients with cerebellum,brainstem,ventricle,thalamus and multifoeal hemorrhage than that in patients with basal ganglion and brain lobe hemorrhage(x2 =4.023,P＜0.05).The hospitalization days of the observation group was longer than that of the control group [(32.7 ± 16.2) versus (17.3 ± 6.7),t=2.93,P＜ 0.01].The mortality of the observation group was higher than that of the control group (24.1％ versus 3.7％),(x2 =8.720,P＜ 0.01).Multivariate Logistic regression analysis showed that age≥ 65 (OR =4.87),underlying lung diseases (OR =5.30),bulbar paralysis (OR =7.39),disorder of consciousness (OR=4.11),NIHSS score ＞ 4 (OR =3.96),invasive airway operations (OR=3.78),gastric tube (OR =4.37),H2-receptor blocking agents application (OR =2.09) were independent risk factors for SAP in acute intraerebral hemorrhage patients.Conclusions Gram-negative bacteria are the main pathogens of SAP in patients with acute cerebral hemorrhage.The patients complicated with SAP after acute cerebral hemorrhage have poor prognosis including prolonged hospitalization period and higher mortality.SAP in acute intraerebral hemorrhage patients is closely related to the following factors:age≥65,underlying lung diseases,bulbar paralysis,disorder of consciousness,NIHSS score ＞ 4,invasive airway operations,gastric tube,H2-receptor blocking agents.

Abstract: Objective　In order to understand the radon exposure level of homes in Chongqing, this survey was carried out on the indoor radon concentration in 38 districts and counties of Chongqing. Methods　According to the population ratio of every 100 000 people, one monitoring site was arranged, and the number of parallel samples was 10% of the distribution sites. The monitoring sites covered 38 districts and counties in Chongqing. A total of 1 019 residential monitoring sites in 38 districts and counties in Chongqing were measured with radon accumulation detectors from July 2020 to June 2021. Results　The five districts/counties in Chongqing having the highest average concentration of residential radon in the year were Xiushan County 78.8 Bq/m3, Qianjiang District 78.0 Bq/m3, Yubei District 73.9 Bq/m3, Youyang County 71.4 Bq/m3 and Shapingba District 69.8 Bq/m3. The five districts/counties with the lowest mean concentration of indoor radon were 37.6 Bq/m3 in Zhongxian County, 36.4 Bq/m3 in Changshou District, 33.7 Bq/m3 in Kaizhou District, 33.2 Bq/m3 in Liangping District and 27.3 Bq/m3 in Wushan County. The concentration levels of radon in four seasons were 46.0 Bq/m3, 53.4 Bq/m3, 45.1 Bq/m3 and 59.5 Bq/m3, respectively. The concentration of radon was higher in Summer and Winter, and lower in Spring and Autumn, and the difference of concentration among four seasons was statistically significant (P<0.001). The radon concentration of newly built buildings after 2017 was relatively high, up to 61.8 Bq /m3, but there was no statistical significance in radon concentration in different building ages (P>0.05). The concentration of radon in rooms of buildings with less than 10 floors was higher, up to 63.2 Bq /m3, and there were significant differences in radon concentration among rooms of different floors (P<0.05). The average annual radon concentration in houses in Chongqing was about (51.6±19.5) Bq/m3, and the average annual effective dose of inhaling radon and its progeny by house-related people was about (1.38±0.52) mSv. Conclusion　The average annual radon concentration level of houses in Chongqing is within the standard limit value recommended by China, but the prevention and control of radon should be strengthened.
