Objective To evaluate effectiveness of guideline-oriented training for community healthcare workers (HCWs) with The Applied Standards for Hypertension Prevention and Control at the Grassroots to provide guidance to hypertension management in communities. Methods In 2003, four community health-care service centers in Beijing were selected and assigned as intervention (one at urban and one at rural) and control (one at urban and one at rural ) groups, respectively. HCWs in the intervention group received guideline-oriented training based on The Applied Standards for Hypertension Prevention and Control at the Grassroots, while HCW in the control group did not. All HCWs participated in tests of the knowledge of hypertension management using the same questionnaire before and after the training to analyze their changes in awareness scores with a full of 32. Results There were 39 and 33 HCWs in the intervention group and 15 and 16 HCWs in the control group, respectively at urban, and 30 and 33 HCWs in the intervention group and 21 and 22 HCWs in the control group, respectively at rural before and after the training were involved in the tests, respectively. After training, overall knowledge scores of hypertension prevention and control in HCWs in the intervention group at urban increased obviously, with an average score of 26 of 32 ( 81.0% ) after training from 15 of 32 (45. 6% ) before it ( P ＜ 0. 01 ) , with a net increase of 28.5% (9/32), as compared to HCWs in the control group. Those at rural increased to 6. 6% (20/32) after training from 40. 7% (13/32) before it ( P ＜ 0.01 ), with a net increase of 22. 2 percent (7/32), as compared to HCWs in the control group. Their awareness of knowledge of hypertension prevention and control significantly improved, with the most obviously in the target of blood pressure control (51.7% vs. 31.5% ) and principles of pharmaceutical therapy (42. 2% vs. 27. 6% ). Conclusions Guideline-oriented training based on The Applied Standards for Hypertension Prevention and Control at the Grassroots can effectively improve community HCWs' awareness of knowledge of hypertension management and should be widely promoted in communities.

Objective To review our experience in the diagnosis and treatment of nonfunctional islet cell tumors(NICT).Method The clinicopathological data of 26 cases of NICT were retrospectively analysed and the medical literature was reviewed.Results In addition to the 26 cases seen in our center,there were 569 cases published in 37 articles in the medical literature.In China,NICT was more common in women.The male to female ratio was about 3 ∶ 7.The mean age of onset of the disease was 35 years old.Most NICT were solitary and malignant,surgery was effective in prolonging long-term survival.Conclusions NICT is rare and it had no specific clinical presentation.BUS and CT are useful for diagnosis and surgery is effective.

Objective To evaluate the use of double balloon endoscopy(DBE) in diagnosis of ulcerative lesions in small intestine.Methods Data of patients diagnosed as small intestinal ulcer under DBE during September 2003 and December 2007 at Nanfang Hospital were analyzed retrospectively.Results Ulcer in small intestine was detected by DBE in a total of 62 patients,including 48 males and 14 females,aging from 10 to 71 years old( mean 43.9 yr).The main clinical manifestations consisted of small intestinal hemorrhage(38/62,61.3%),abdominal pain(16/62,25.8%),abdominal distention(5/62,8.1%),loss of weight(2/62,3.2%),and diarrhea(1/62,1.6%).The ulcers were diagnosed endoscopically as Crohn's disease(CD) in 53 cases(85.5%),drug induced lesions in 4(6.5%),nonspecific chronic inflammation in 2(3.2%),lymphoma in 2(3.2%) and tuberculosis in 1(1.6%).They were all microscopically diagnosed as chronic inflammation.Of the 62 patients,32(51.6%) underwent surgery.In 30 cases of CD diagnosed by DBE,22 were confirmed by post-surgery pathology(malignant cells were found in 3),while in the other 8 cases,4 were diagnosed as lymphoma,3 as Behcet's disease and 1 as tuberculosis.Meanwhile,the 1 case of tuberculosis and 1 lymphoma diagnosed by DBE were confirmed as CD after operation.The overall accurate diagnosis rate of small intestinal ulcerative lesions by DBE was 68.8%(22/32).Conclusion DBE is valuable in diagnosis of ulcerative lesions in small intestine,but surgery should be included into consideration to confirm the diagnosis when necessary.

Objective To evaluate the effectiveness of single balloon enteroscopy (SBE) in diagno-sing of suspected lesions in small intestine. Methods Data of 23 patients with suspected small intestinal disease, who underwent SBE (Olympus) between February 2009 and August 2009, were retrospectively studied. A total of 34 procedures were performed in 23 patients. The indications for the examination were suspected obscure gastrointestinal bleeding (n = 9), abdominal pain (n = 7), suspected intestinal tumor re-vealed by capsule endoscopy (n = 4), and Crohn disease (n = 3). Results The average preparation time of SBE was less than 5 minutes. The mean procedure time was 61±25 minutes and 67±28 minutes for the oral and anal routes, respectively. Examination of whole length of small intestine was achieved in 6 patients. The diagnostic rate of small-intestinal lesions was 60. 9%, and no severe complications including perforation occurred. Conclusion SBE is safe and easy to prepare and perform, which can be a useful diagnostic and therapeutic tool for suspected small bowel disease.

Objective To investigate the relation between the balloon occlusion test ( BOT) and the anatomy of the circle of Willis ( CW) , and to explore the role of balloon occlusion test in the treatment of internal carotid artery permanent occlusion. Methods Selected the clinical data of 49 patients (52 sides) who had BOT in our hospital from October 2009 to June 2015,and analyzed the relationship be-tween the occurrence rate of anterior communicating artery ( AcoA) / posterior communicating artery ( PcoA) and the positive rate of BOT retrospectively. Results The occurrence rate of the AcoA was 97. 9%, and the occurrence rate of PcoA in one side was 82. 7%. Negative rate BOT accounted for 92. 3% and AcoA occurred in all, while the positive rate accounted for 7. 7%, including 2 cases of right superior ar-teria cerebri anterior combined with ipsilateral PcoAs absence, 1 case of left superior arteria cerebri anterior combined with ipsilateral PcoAs absence, and 1 case of AcoA and PcoAs absence. Conclusion Before the permanent occlusion of the internal carotid artery, it’ s necessary to clarify the redistribution of the compensatory way of blood flow in the AcoA-absent cases. Implementing permanent occlusion for cases with complete circle of Willis would cause less ischemic risk.

center.Twenty-one patients had postoperative surgery-related complications,including 11 with bile leakage,8 with pulmonary infection and 2 with abdominal bleeding.Two patients died in the perioperative period.② Postoperative adjuvant treatment:26 patients underwent postoperative adjuvant chemotherapy.Chemotherapy regimen:gemcitabine + oxaliplatin were used in 12 patients,gemcitabine + tegafur in 7 patients,gemcitabine + cisplatin in 6 patients,oxaliplatin + tegafur in 1 patient.(3) Results of postoperative pathological examination.The postoperative pathological type of 305 patients:257,23,6,5,4,3,3,2,1 and 1 patients were respectively confirmed as pure adenocarcinoma,adenocarcinoma combined with squamous cell carcinoma,adenocarcinoma combined with neuroendocrine carcinoma,mucinous adenocarcinoma,neuroendocrine carcinoma,adenocarcinoma combined with mucinous carcinoma,squamous cell carcinoma,sarcomatoid carcinoma,adenocarcinoma combined with sarcomatoid carcinoma,adenocarcinoma combined with signet-ring cell carcinoma.Degree of tumor differentiation:highdifferentiated,moderate-differentiated and low-differentiated tumors were detected in 37,130 and 121 patients,respectively,17 with unknown differentiated degree.Of 305 patients,16 and 32 patients had respectively vascular invasion and nerve invasion.The number of lymph node dissected of 305 patients was 8±5,with positive lymph node of 0 (range,0-9),including 121 with lymphatic metastasis (26 with jumping lymphatic metastasis).TNM staging of 305 patients:stage 0,Ⅰ,Ⅱ,ⅢA,ⅢB,ⅣA and ⅣB were detected in 7,18,13,137,57,11 and 62 patients,respectively.(4) Follow-up:245 of 305 patients were followed up for 18.0 months (range,6.0-70.0 months).The survival time,1-and 3-year survival rates were respectively 29.5 months (range,0.5-69.9 months),71.6％ and 45.8％.One hundred and twenty-two patients died during the follow-up.(5) Prognostic factors analysis:the results of univariate analysis showed that preoperative level of bilirubin,pathological type,degree of tumor differentiation,liver invasion,vascular invasion,nerve invasion,T staging,N staging and postoperative chemotherapy were factors affecting prognosis of patients with primary GBC (x2 =10.26,3.96,45.89,34.64,12.75,27.05,35.09,39.44,4.40,P＜0.05).The results of multivariate analysis showed that low-differentiated tumor,liver invasion and N2 staging were independent risk factors affecting prognosis of patients with primary GBC [odds ratio (OR)=1.90,1.71,1.46,95％ confidence interval (CI):1.34-2.70,1.15-2.52,1.17-1.82,P＜0.05],and postoperative chemotherapy was a protective factor affecting prognosis of patients with primary GBC (OR=0.35,95％ CI:0.15-0.82,P＜0.05).Conclusions For patients with primary GBC undergoing radical resection,D2 lymph node dissection should be performed routinely.The low-differentiated tumor,liver invasion and N2 staging are independent risk factors affecting prognosis of patients,and postoperative chemotherapy is a protective factor.

Objective:To investigate the independent predictors of the long-term clinical outcomes in patients with branch atheromatous disease (BAD) in lenticulostriate artery (LSA) territory.Methods:Patients with LSA-BAD admitted to the Department of Neurology, Zhongnan Hospital of Wuhan University from January 1, 2016 to June 1, 2019 were enrolled retrospectively. Their demography, vascular risk factor, and baseline clinical data were collected. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the severity of stroke. The clinical outcomes were evaluated by the modified Rankin Scale at 6 months. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcomes in patients with LSA-BAD. Results:A total of 81 patients with LSA-BAD were enrolled. Their age 59.20±11.75 years (range, 39-81 years), 53 were male (65.4%), and median baseline NIHSS score was 1.0 (interquartile range, 0-4.0). Forty-one patients (50.6%) received intravenous thrombolysis. At 6-month follow-up after the onset, 63 patients (77.8%) had a good outcome, and 18 (22.2%) had a poor outcome. The baseline NIHSS score of the poor outcome group was significantly higher than that of the good outcome group (6.5 [0-9.0] vs. 1.0 [0-3.0]; Z=2.395, P=0.017), while the proportion of mild stroke (61.6% vs. 98.4%; χ2=17.595, P<0.001) and patients receiving intravenous thrombolysis (38.9% vs. 54.0%; χ2=4.450, P=0.035) were significantly lower than those of the good outcome group. Multivariate logistic regression analysis showed that after adjusting for other confounding factors, venous thrombolysis was independently correlated with the good outcome (odds ratio 0.099, 95% confidence interval 0.011-0.924; P=0.042), while the high baseline NIHSS score was independently associated with the poor outcome (odds ratio 1.736, 95% confidence interval 1.262-2.388; P=0.001). Conclusion:Intravenous thrombolysis is helpful to improve the outcomes of patients with LSA-BAD, and a higher baseline NIHSS score is an independent predictor of the poor outcome.

Objective:To understand the status of knowledge, attitude and practice of metabolic syndrome(MS) among the elderly in the community and analyze its influencing factors, so as to provide guidance for the prevention and treatment of MS.Methods:From January 2021 to August 2021, permanent residents(residence duration ≥6 months)aged 65 and above with regular health check examination in Fangzhuang Community Health Service Center of Fengtai District, Beijing were investigated using self-designed MS knowledge, attitude and practice questionnaire.After excluding 34 incomplete questionnaires, the 491 valid questionnaires were recycled with questionnaire valid percentage of 93.5%(491/525). The survey results were analyzed by descriptive analysis, Mann-Whitney U test, Kruskal-Wallis H test and multiple linear regression analysis and multiple linear regression.Results:The scores of MS knowledge, attitude and practice of the elderly in the community were 7(5, 10), 9(8, 10)and 19(18, 21)respectively.The correct answer rate of the diagnostic criteria of MS components was less than 50%.The score of knowledge about MS in the elderly was positively correlated with the scores of attitudes( r=0.263)and practice( r=0.134)(all P<0.01). The results of univariate and multiple linear regression analysis showed that gender, attending educational lectures and the prevalence of MS were the influencing factors of MS knowledge score(all P<0.05). Leisure time, attending educational lectures, pre-retirement occupation and regular health check examination were the influencing factors for MS attitude score(all P<0.05); attending educational lectures, leisure time, regular health check examination and pre-retirement occupation were the influencing factors for MS practice score(all P<0.05). Conclusions:The elderly in the community have a low level of knowledge about the components and diagnostic criteria of MS, but have a positive attitude and practice towards the prevention and treatment of MS.The level of knowledge, attitude and practice of MS is affected by health education lectures, occupation, regular health check examination and other factors.Health education on the diagnostic criteria and the awareness of disease prevention for the elderly in the community should be strengthened to improve the levels of the knowledge, attitude and practice of MS.
