One hundred forty-four residents registered at department of anesthesia of West China Hospital from 1999 to 2010.The duration of residency training is 5 years (3 + 2).The residents enrolled during 1999-2002 were on the staff.They were assigned to work at this hospital after graduation from medical school and became staff anesthesiologist of this hospital after 5 year training.The residents enrolled during 2003-2010 were trainees and not on the staff.They had to apply for a job as anesthesiologist somewhere after 5 year training.After 3 year training the residents are qualified to undergo subspecialty training.Thirty-nine of the 144 residents dropped out of the training program.The reasons for their withdrawing from the program included finding a regular job,failing the qualifying examination,changing profession studying abroad and death.In order to reduce dropout rate,correct public opinion on the importance of residency training,raising the quality of the residents and improving income of the residents are needed.

Objective To study the clinical significance of detection of infectivity index in patients before transfusion. Methods A total of 12 863 patients in hospital were examined for hepatitis B virus surface antigen(HBsAg),anti-hepatitis C virus(anti-HCV),anti-AIDS virus(anti-HIV)and treponemiasis test(TRUST)before operation and transfusion. Results The positive rates of HBsAg,anti-HCV,anti-HIV and TRUST were 12.59%,1.90%,0.02%and 0.80%respectively.Conclusion The detection of infectivity index before transfusion has a very,important role in the prevention of blood transmissible disease and reduction or medical treatment dispute caused by infection after transfusion.

Objective To explore the effect of GAS MAN assisted instruction on theory learning of volatile anesthetics in anesthesiology residency training.Methods A total of 32 residents in the first stage of anesthesiology training were enrolled and randomly assigned to either study(S) or control (C) group.Theory-test l(Test-1) was conducted for all residents after the lecture-based learning (LBL).Next,reference book self-reading strategy was used in both groups while computer-based simulation(CBS) using GAS MAN was only developed in S group.Then,theory-test 2(Test-2)was conducted for residents in both groups and residents in S group completed the questionnaire smvey.In addition,thirty-four resident teachers observed the CBS courses and completed the questionnaire smvey.Results The mean scores of Test-1 did not differ significantly between the two groups(P=0.64).However,the mean Test-2 score of S group(81.3 ± 13.6) was significantly higher than that of C group(61.3 ± 15.4) (P=0.001).100％(16/16) residents believed that CBS was beneficial to the theoretical study of volatile anesthetics,93.8％(15/16) residents considered GAS MAN could help understand the concepts and improve efficiency during self-learning.97.1％ (33/34) and 91.2％ (31/34)resident teachers agreed that CBS was helpful for analyzing complex concepts and improving study effectiveness,respectively.Conclusions CBS using GAS MAN improves theory knowledge and study effectiveness for anesthesia residents.Both residents and resident teachers find GAS MAN highly ac ceptable.Therefore,GAS MAN has the potential to be the assistant teaching tool for LBL in anesthesiology residency-training program.

This article provides an overview of the severe acute respiratory syndrome (SARS) epidemics in mainland China and of what we have learned since the outbreak.The epidemics spanned a large geographical extent but clustered in two regions:first in Guangdong Province,and about 3 months later in Beijing and its surrounding areas.The resulting case fatality ratio of 6.4％ was less than half of that in other SARS-affected countries and regions,partly due to younger-aged patients and a higher proportion of community-acquired infections.Strong political commitment and a centrally coordinated response were most important for controlling SARS.The long-term economic consequence of the epidemic was limited.Many recovered patients suffered from avascular osteonecrosis,as a consequence of corticosteroid usage during their infection.The SARS epidemic provided valuable experience and lessons relevant in controlling outbreaks of emerging infectious diseases,and has led to fundamental reforms of the Chinese health system.Additionally,the epidemic has substantially improved infrastructures,surveillance systems,and capacity to response to health emergencies.In particular,a comprehensive nationwide internet-based disease reporting system was established.

Objective To observe the effects of scalp acupuncture on cognitive impairments after traumatic brain injury (TBI). Methods 42 cases of TBI were randomized into experiment group (n=23) and control group (n=19). The control group accepted cognitive training and Donepezil, and the experiment group accepted scalp acupuncture in addition for 3 months. They were assessed with event related potential P300 and Montreal Cognitive Assessment (MoCA) before, 1 and 3 months after treatment. Results The results of P300 and MoCA improved significantly 3 months after treatment (P<0.001) in both groups, and improved more in the experiment group than in the control group (P<0.001). Conclusion Scalp acupuncture could improve outcomes of cognitive impairments after TBI.

Objective To study the difference and clinical significance of serum Angiopoietin-2 (Ang-2) level in gastric cancer, precancerous disease and the changes in post operation follow-up patients.MethodsSerum Ang-2 and CEA levels were detected with ELISA method in 158 gastric cancer patients, 31 chronic astrophic gastritis patients, 38 gastric adenomatous polyp patients, 28 chronic gastritis patients with benign gastric ulcer and 30 healthy controls.The changes of serum Ang2 levels in 131 patients with radical gastrectomy were measured in 2-year post-operational followed-up and the prognosis was also evaluated.The correlation between serum Ang-2 level and the pathologic character of gastric cancer was analyzed.ResultsThe serum Ang-2 and CEA levels of gastric cancer group were (331.8± 64.3) μg/L and (42.6 ± 37.3) μg/L, respectively, which were significantly higher than those of healthy control group [(187.4±32.7) μg/L and (4.2±3.1) μg/L]and benign gastric ulcer group [(197.3±35.4) μg/L and (4.5±3.2) μg/L](all P ＜0.01).The serum Ang-2 level in chronic astrophic gastritis group was also markedly increased (P＜0.05), however there was no significant change in CEA level.There was no obvious change of Ang-2 and CEA level in gastric adenomatous polyp group (P＞0.05).Pre-operation serum Ang-2 levels of the relapse group and the metastasis group were significantly higher than that of no relapse group (P＜0.05).Post-operation serum Ang-2 level of no relapse group decreased to normal range in 1 month and without obvious increase in 2 years follow-up.The serum Ang-2 level of the relapse group also decreased to normal range in 1 month post-operation, while which was significantly higher than that of no relapse group and normal control group from 6 months to 2 years after operation (P＜0.01).Serum Ang-2 level of the metastasis group was markedly higher than that of no relapse group and normal control group during 2 years after operation (P＜0.01).The 2-year survival rate of no relapse group was significant higher than that of relapse group and metastasis group.The change of serum Ang-2 level was correlated with in the gastric cancer differentiation degree, TNM pathologic classification, lymphatic metastasis, distant metastasis, the depth of invasion and the tumor size (P＜0.01), however not correlated with histopathology type and the location of tumor.ConclusionSerum Ang-2 level may be a new and valuable gastric cancer marker, which will help to monitor tumor relapse, migration and prognosis assessment.

Objective:To analyze the concerning guarantee mechanisms during the transformation of the com-munity health service mode. Method:Purposive sampling was adopted. Twelve community health service centers in Beijing, Shanghai, Zhengzhou, and Chengdu, where the transformation of the community health service mode was pi-loted earlier and representative, were selected as the field survey sites. The qualitative method was used to collect da-ta accompanied by the quantitative method. Results: The guarantee mechanisms related to the transformation of the community health service mode could be concluded into four main types:collaboration mechanism, health profession-al training mechanism, incentive mechanism, and policy guarantee mechanism. All of the four mechanisms contribu-ted to the improvement of general teamwork, dual referral systems, and the development of contract and appointment services. Conclusion:During the transformation of the community health service mode, priority strategies include top-down design, health professional training mechanisms, and performance-based incentive mechanism, all of which should be implemented in the future.

Objective:To analyze the structure modes of general practice teams in community health care cen-ters in order to provide empirical evidence for the transformation of the community health service mode. Method:Pur-posive sampling was adopted. Twelve community health service centers in Beijing, Shanghai, Zhengzhou and Cheng-du, where the transformation of the community health service mode was piloted earlier and representative, were se-lected as the field survey sites. The qualitative method was used to collect the data accompanied by the quantitative method. Results:The structure models of general practice teams could be divided into four types:1) general practi-tioner+nurse+nurse assistant+pharmacist, 2) physician (general practitioner, herbalist physician) +nurse+com-munity volunteers, 3 ) physician ( general practitioner/herbalist physician ) +nurse +assistant +community volun-teers, and 4) general practitioner+nurse+assisting team (professionals of public health and maternal care, etc) +supportive team ( pharmacists, health technician, etc) . Conclusion:The paper verified the common sense conclusion that general practitioners should play an essential role in general practice teamwork. The four general practice team models analyzed above positively contributed to the improvement of efficiency and quality, the relationship between health professionals and patients, the promotion of community participation, and the combination between preventive care and clinical care.

Objective:To analyze the progress of the contracting service model in community health centers in the typical areas in China, and provide empirical evidence for the hierarchical system targeted to make first contact and orderly dual transfer. Methods: Purposive sampling was adopted. Twelve community health centers in Beijing, Shanghai , Zhengzhou and Chengdu areas where the general practitioner model was conducted earlier and set to be the representative one, were selected as the field survey sites. A thematic framework analysis was used to describe the key factors around the contacting service model. Results:This model was developed around the following key factors:using the general practice team as the main service provider, taking the patients with chronic diseases as the main contracting groups and extending to their family members with the number of contracted ranging around 1500~2000 , freely providing both essential public health and medical services, fully using the family physician room as the con-tracting service platform and highlighting the actively serving concept, building the financial and non-financial incen-tives, health insurance benefits and green transfer mechanisms in order to efficiently guarantee the contracting service development. Conclusions: Based on the information platform, the contracting service model in the sample sites played a great role in the appointment and referral services development as well as the self-health management among residents, improving the relationship between physicians and patients, and promoting the formation of orderly health service pursuing pattern.

Objective:To study the chronic disease management’s key factors in community health service insti-tution based on the Innovative Care for Chronic Conditions Framework ( ICCC ) . Methods: The purposive sampling method was adopted. Twelve community health service centers were selected as the field survey sites in Beijing, Shanghai, Zhengzhou and Chengdu. During the key factors description at macro-, meso-and micro-level in the IC-CC framework, thematic framework analysis was used to describe the key factors at maro-, meso-and micro level in the ICCC framework. Results:From the community health institutions’ perspective, the key factors at meso level in the ICCC framework played a better role in the management of chronic conditions while the key factors in both macro and micro level still lacked. Conclusion:Based on the ICCC framework, the management of chronic diseases needs to emphasize the cooperation with relevant departments outside the health area and legislative strategies at macro level, the ability of community supporters to mobilize and coordinate resources at meso level and the improvement of self-management skills for the patients with chronic diseases.
