Objective To evaluate effectiveness of prevention and treatment for patients with chronic obstructive pulmonary disease (COPD) for one year at community health-care service (CHS)centers. Methods A quasi-experiment design was used to evaluate effectiveness of community management for patients with COPD who visited and registered at Xiaokunshan and Xinbang CHS centers in Songjiang district of Shanghai in 2008, with COPD patients from Xiaokunshan community CHS center as management group and those from Xinbang as control. Measures for community management included training for local general practitioners in essential knowledge of COPD prevention and treatment, allocation of necessary drugs for COPD treatment, and health education for COPD patients and their family members. No special measures were taken for control group except routine treatment. Results A total of 132 patients were diagnosed as COPD according to their pulmonary function on 2008, 61 at Xiaokunshan and 71 at Xinbang CHS canters.One hundred and two patients, 47 at Xiaokunshan and 55 at Xinbang, finished one-year follow-up. Five patients from Xiaokunshan who were smokers at their first visits and three of them quitted smoking after oneyear management. Meanwhile, none of nine smoked patients from Xinbang quitted smoking in the same period. There was no statistically significant difference in symptom scores, pulmonary function, and forced expiratory volume at the first second (FEV1) between patients in the two groups during one-year follow-up.Average score of quality of life in patients at Xiaokunshan dropped to 39. 12 after one-year management from 46. 96 at their first visits, and that in patients at Xinbang increased to 62. 11 from 56. 55 (P＜0.01).Average six-minute walking distance (6-MWD) in patients at Xiaokunshan reduced to 354. 26 meters after one-year management from 361.66 meters at their first visits, meanwhile that in patients at Xinbang reduced to 351.18 meters from 398.07 meters (P =0. 008). Scores of functional dyspnea in patients at Xiaokunshan fell to 0.34 from 0.40 at their first visit, meanwhile that in patients at Xinbang increased to 1.00 from 0.95(P =0.038). During the one-year follow-up, 13 patients at Xiaokunshan and 53 at Xinbang visited emergency departments for treatment, and four at Xiaokunshan were hospitalized and none died, and five at Xinbang were hospitalized due to acute exacerbation of COPD and four of them died. Conclusions The study suggests that strengthening prevention and treatment for COPD patients at community level by general practitioners, patients themselves and their family members can improve their quality of life, reduce emergency visits and hospitalization, alleviate dyspnea symptoms and delay the decline of 6MWD.

Objective To investigate the risk factors of polytrauma combined with multiple organ dysfunction syndrome (MODS).Methods A retrospective case control study was performed on the clinical data of 299 polytrauma patients admitted to the Affiliated Hospital of Jiangsu University from December 2011 to June 2017.The collected information included gender,age,length of hospital stay,number of injured parts,injury severity scores (ISS),neutrophil count,leukocyte level,hemoglobin level,platelet count,activated partial thromboplastin time (APTI),and D-dimer level within 24 hours since admission.In addition,shock within 24 hours since admission,infection after 3 days since admission,damage control surgery,underlying diseases and prognostic outcomes were also recorded.All the patients were divided into MODS group (94 patients) and non-MODS group (205 patients).Univariate and multivariate logistic regression analyses were used to determine the risk factors of polytrauma combined with MODS.Receiver operating characteristic (ROC) curve was applied to further analyze those risk factors identified by the former analyses.Results In the univariate analysis,there were statistically significant differences between the two groups in the number of injured parts,ISS,hemoglobin level,platelet count,APTT,D-dimer level within 24 hours since admission,shock within 24 hours since admission,infection after 3 days since admission,damage control surgery and prognostic outcomes (P ＜ 0.05).No significant differences were found in gender,age,underlying disease,length of hospital stay,neutrophil level,the leukocyte level within 24 hours since admission between the two groups (P ＞ 0.05).The multivariate logistic regression analysis showed that ISS (OR =1.048),shock within 24 hours since admission (OR =3.913),infection after 3 days since admission (OR =27.715),and D-dimer level within 24 hours since admission (OR =1.015) were significantly associated with polytrauma combined with MODS (P ＜ 0.05).In addition,the area under ROC curve of ISS was 0.726 (95 ％ CI 0.667-0.784),and the area under ROC curve of D-dimer was 0.638 (95％ CI 0.571-0.706).Conclusions The risk factors of polytrauma patients combined with MODS include ISS,infection after 3 days since admission,D-dimer level and shock within 24 hours since admission.In the treatment of polytrauma patients,attention should be paid to assessment of injury severity and coagulation function,active resuscitation to correct shock,prevent and control infection,which can reduce and prevent the risks for polytrauma patients combined with MODS.

Objective To observe the clinical effect of etomidate combined with propofol on laparoscopic cholecystectomy.Methods Eight patients undergoing laparoscopic cholecystectomy cho sen from March 2015 to April 2016 in our hospital,falling into ASA Ⅰ or Ⅱ grades,randomly divided into four groups,20 in each.Group A was administered of propofol (2 mg/kg);group B etomidate (0.3 mg/kg);group C etomidate (0.15 mg/kg) combined with propofol (1 mg/kg);group D etomidate (0.1 mg/kg) combined with propofol (1.5 mg/kg).Systolic blood pressure,diastolic blood pressure and heart rate of the four group were compared at the following six time points:before anesthesia induction(T0),1 min before intubation (T1),the intubation moment (T2),1 min after intubation (T3),5 min after intubation (T4),15 min after intubation (T5).The serum of four groups were collected at the time before anesthesia induction (T0),30 min after anesthesia induction (Tb),2 h after induction of anesthesia (Tc) and 24 h after anesthesia induction(Td).Aldosterone,cortisol and adrenocorticotropic hormone in serum were tested by radioimmunoassay.The incidence of adverse reactions such as injection pain and myoclonus during induction,and postoperative nausea and vomiting of the four groups were recorded and compared.Results Compared with T0,HR,SBP at T1,T4 and T5 were significantly decreased in group A (P＜0.05).SBP at T2 were significantly increased in group B (P＜0.05),and SBP at T1 and T5 were significantly decreased in group C (P＜0.05).There was no significant difference of HR at T1,T2,T3,T4 and T5 in group B and C.Compared with T0,HR,SBP at T1,and T5 were significantly decreased in group D (P＜0.05).There was no significant difference in hemodynamics among the four groups.Compared with T0,the levels of Cor and ALD at Tb and Tc were decreased in group B and C (P＜0.05).And the level of ACTH of B and C in Tc were significantly increased (P＜0.05).Compared with group A,the levels of Cor and ALD of group B and C were significantly decreased at Tb and Tc (P＜0.05).Compared with group B,the levels of Cor and ALD of group C and D showed less decrease at Tb and Tc (P＜0.05).And compared with group C,the levels of Cor and ALD of group D showed less decrease at Tb and Tc (P＜0.05).Conclusion Etomidate combined with propofol induced can reduce the side effects induced by propofol or etomidate alone,which is an ideal way of anesthesia induction.
