Objective To understand awareness of basic knowledge on control and prevention for chronic obstructive pulmonary disease (COPD) among general practitioner in community health service centers. Methods Questionnaire survey was conducted among 593 general practitioners at 15 community health service centers in a district of Shanghai in the morning of February 26, 2008. Results Five hundred and forty-two of 593 ( 91.4% ) general practitioners surveyed knew that chronic obstructive pulmonary disease can be abbreviated as COPD, and 315 of them (53.1%) thought they knew the main contents of the "Guidelines for Prevention and Control of Chronic Obstructive Pulmonary Disease". No pulmonary function instrument was equipped at all 15 community health service centers surveyed, and 501 of 593 ( 84.5% ) general practitioners knew spirometry is gold standard for diagnosis of COPD. Only 115 ( 19.4% ) general practitioners knew that COPD can be categorized as acute exacerbation and stable stage. One hundred and sixty-three of them (27.5%) knew that drug therapy should be maintained in COPD patients for long term following effective treatment, 328 (55.3%) recognized that treatment for COPD patients was still needed in their stable stage, and 312 (52.6%) believed that antibiotics may not be necessary and 465 (78.4%) thought that inhalation therapy was the choice of treatment for acute exacerbation of COPD. Two hundred and thirty-five of them (39.6%) knew that oxygen inhalation should be more than 15 hours per day in regular family therapy. The investigation showed that 365 (61.6%) general practitioners had participated in training for COPD-related knowledge, only one or two times a year. Awareness of COPD knowledge was significantly poorer in rural practitioners than that in urban community ones. Conclusions Basic knowledge of prevention and treatment for COPD was seriously lack in general practitioners, so it is a necessity to strengthen training for them.

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 study the feasibility of using a double purse-string bridging pancreaticojejunostomy in total laparoscopic pancreaticoduodenectomy (TLPD).
Methods:
A database of 35 patients who underwent TLPD using a double purse-string bridging pancreaticojejunostomy from January 2016 to January 2019 in Jinhua Hospital of Zhejiang University was retrospectively reviewed. The perioperative outcomes were analyzed.
Results:
All the 35 patients underwent TLPD successfully. The surgery time was (370.2±33.5) min, and the time of constructing the pancreaticojejunostomy was (28.4±12.6) min. The hospital stay after surgery was (14.2±6.9) days. Five patients developed postoperative complications, including pancreatic fistula in 3 patients, bile leakage in 1 patient, gastroparesis (complicated with abdominal infection) in 1 patient, and abdominal infection in 3 patients (2 patients with pancreatic fistula, and 1 patient with gastroparesis). All the patients with complications responded well to conservative treatment.
Conclusions
A double purse-string bridging pancreaticojejunostomy was simple and widely applicable. It is safe and feasible in total laparoscopic pancreaticoduodenectomy and should be promoted in clinical practice.

Objective To study of short-term rehabilitation index and its relationship with medium-term function in male rectal cancer after laparoscopic surgery. Methods A retrospective analysis was made of 60 cases with rectal cancer who received laparoscopic radical resection in our hospital. In the observation group,the pelvic autonomic nerves were retained in 30 cases,and 30 cases in the control group were not retained. The levels of se-rum prealbumin(PA),C reactive protein(CRP),white blood cell count(WBC)and blood cortisol(Cor)were compared between the 2 groups. The independent influence factors of erectile and ejaculatory disorder were fol-lowed up at 6 months after operation. Results Postoperative exhaust time,defecation time,postoperative extuba-tion time,ambulation time,postoperative hospitalization time in the observation group were significantly shorter than those in the control group(P < 0.05). The level of serum CRP,WBC and Cor in the observation group was significantly lower than those of the control group at 3 d after operation,and the level of PA was significantly high-er than that of the control group(P < 0.05).The independent influence factors of erectile dysfunction were the level of PA and CRP at 3d after operation(P < 0.05).The independent influence factors of ejaculatory dysfunction were PA level at 3D after operation(P < 0.05). Conclusion Pelvic nerve protection in laparoscopic surgery is helpful to promote the postoperative recovery. High PA at short term after operation may be one of the medium-term protec-tion mechanisms for sexual function.

OBJECTIVETo observe the effect of the decomposition products of necrotic tissues from wounds on the serum levels of inflammation factors in comparison with endotoxin.
METHODSThirty adult New Zealand rabbits were randomly divided into 3 groups and received injections of saline, necrotic tissue homogenate or endotoxin. From each rabbit, blood samples (2 ml) were collected from the central artery of the ears at 0, 2, 6, 12, 24, 30, 36, 48, and 60 h after the injection for measurement of serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1) and IL-6.
RESULTSThe serum level of TNF-α, IL-1 and IL-6 in the rabbits increased 2-4 h after injection of the necrotic tissue homogenate and reached the peak level at 12 h, followed by a gradual reduction since 36 h. No obvious changes in the levels of the inflammatory factors were found in saline group (P<0.01). Compared with endotoxin, necrotic tissue homogenate resulted in an early increment (2-4 h vs 5-6 h) and significantly higher peak levels (at 30 h) of the inflammation factors (P<0.05). Curve fitting showed a distinct difference between necrotic tissue homogenate and endotoxin in their effect on the inflammatory factors.
CONCLUSIONThe necrotic tissue decomposition products contain toxic substances that possess a different toxicity profile from endotoxin, and their toxicity can be even stronger.

OBJECTIVE:
To discuss the disease incidence of bronchial asthma (BA) complicated with allergic rhinitis (AR) and the correlation of their age, classification, concomitant symptom.
METHOD:
Four hundred-nine cases of AR were identified by means of random sampling, physical examination, laboratory test and questionnaire. According to the diagnostic criteria of BA, they were divided into two groups: group I ( control group) including 298 cases suffering from only AR, group II ( experimental group) 191 cases of BA concomittent with AR.
RESULT:
1) This study showed that BA concomittent with AR account for 39% of all cases; 2) Incidence of aspirin triad syndrome (asthma, rhinopolyps and aspirin intolerance) was significantly different in two groups (P<0.01); 3) As for age group distribution, there was significant difference between groups in age segment 10-19 and 40-49 (P<0.05); 4) Disease classification: there were significant differences in the incidence of moderate to severe intermittent AR, mild continuous AR, and moderate to severe continuous AR between two groups (P<0.05); 5) Other major concomitant diseases and symptoms distribution; the concomittant occurrence of allergic pharyngitis, sinusitis, conjunctivitis, secretory tympanitis, hypertrophic rhinitis, dermatosis, discomfort of gastrointestinal tract, and headache of unknown origin were significantly different between two groups (P<0.05). The difference above showed that the occurrence in experimental group was higher than that in control group.
CONCLUSION
the incidence of BA complicated with AR were relatively high in Datong, with a peak incidence at age 10 to 19 and 40 to 49. The common types of disease were moderate to severe intermittent AR, mild continuous AR, and moderate to severe continuous AR. The number of patients with BA complicated with AR were growing.
