Objective To investigate the strategies of nutritional therapy for severe acute pancreatitis (SAP) patients.Methods Two hundred and eight patients with SAP were randomly divided into early enteral nutrition (EEN) group,late enteral nutrition (LEN) group and total enteral nutrition (TPN) group.EEN group received enteral nutrition through nasojejunal tube feeding within 72 hours in the course of disease,LEN group received the same treatment after 6 d in the course of disease,TPN group received total enteral nutrition.The index of nutrition,incidence of complication were recorded,efficacy and safety were analyzed.Results EEN group included 67 cases,while 72 cases in LEN group and 69 cases in TPN group.The incidence rate of malnutrition after 14 d of treatment in EEN group and LEN group was significantly lower than that in TPN group [59.7％ (40/67),58.3％ (42/72) vs.84.1％ (58/69),P ＜0.05],but the difference between EEN group and LEN group was not statistically significant (P ＞ 0.05).There was no statistically significant difference in the incidence of hyperlipidemia and hyperglycemia among three groups (P ＞ 0.05).The expression level of albumin,prealbumin and retinol-binding protein after 14 d of treatment in three groups compared with those before treatment and the differences were statistically significant (P ＜ 0.05).The expression level of albumin,prealbumin and retinol-binding protein after 14 d of treatment in EEN group and LEN group compared with those in TPN group and the differences were statistically significant (P＜ 0.05),there was no statistically significant difference between EEN group and LEN group (P＞ 0.05).The incidence rate of total infections,abdominal infections,bloodstream infections,secondary superinfections in TPN group were significantly lower than those in EEN group and LEN group [62.3％(43/69) vs.25.4％ (17/67),19.4％(14/72) ;21.7％(15/69) vs.4.5％(3/67),6.9％ (5/72);39.1％(27/69) vs.14.9％(10/67),11.1％(8/72) ;33.3％ (23/69) vs.9.0％ (6/67),9.7％(7/72),P ＜ 0.05],there was no statistically significant difference in the incidence of peripancreatic infections,lung infections among three groups (P ＞ 0.05).There was no statistically significant difference in the incidence of total infections,different infections between EEN group and LEN group.There was no statistically significant difference in the incidence of noninfections among three groups (P ＞ 0.05).The rate of recovery in EEN group and LEN group was significanby higher than that in TPN group [91.0％ (61/67),94.4％ (68/72) vs.81.2％ (56/69),P ＜ 0.05],but the difference between EEN group and LEN group was not statistically significant (P ＞ 0.05).Conclusion Early enteral nutrition therapy for SAP patients is safe and effective,and could significantly improve the prognosis of patients.

Objective To analyze the literature distribution and research status of benign prostatic hyperplasia (BPH) in the elderly published in Chinese Medical Association journals.Methods The literatures of elderly BPH published in 88 kinds of Chinese Medical Association journals from 2009 to 2013 were collected.The publication year,distribution,content,author,institution and region of these literatures were analyzed.Results From 2009 to 2013,203 articles about elderly BPH were published in 10 kinds of journals.These literatures were published mostly in 2013 (50 articles,24.6％),secondly in 2010 (46 articles,22.7％) and 2009 (43 articles,21.2％),which were mostly published in Chinese Journal of Geriatrics (87 articles,42.9 ％).Most researches were focused on the fields of clinical treatment of BPH in the elderly,etiology,cross-sectional investigation and perioperative nursing,while the progresses in pathophysiology and diagnosis were relatively small,and the most published form was treatise (166 articles,81.8％).Authors who published the most articles were Yang Yong from Department of Urology Surgery in PLA General Hospital and Zhang Xianghua from Department of Urology Surgery in Peking University First Hospital (both,4 articles,3.5 ％),the institutions which published the most articles were Beijing Hospital and Beijing Chaoyang Hospital (both,9 articles,4.4 ％),and the provinces or cities which published the most articles were Beijing (75 articles,36.9％),Shanghai and Zhejiang (both,17 articles,8.4％) and Hunan (16 articles,7.9％).Among the 203 articles,35 articles (17.2％) were supported by founds.Conclusions Chinese Medical Association journals are the important sonrce to acquire literatures on elderly BPH for medical workers.The distribution of journals is relatively concentrated,but the distribution of author,institution and region in these articles is dispersed.Studies on clinical treatment of elderly BPH,etiology,inventory survey and perioperative nursing are especially concerned within nearly 5 years.

Objective To explore the application value of endoscopic ultrasonography (EUS) in the diagnosis of suspected obstructive jaundice in acute biliary pancreatitis and its effect on treatment outcomes. Methods Clinical data were retrospectively collected in 96 patients with acute biliary pancreatitis (ABP) who were suspected obstructive jaundice. Patients were divided into early EUS scanning group (EES) and delay EUS scanning group (DES). Clinical treatment results and test results were compared between the two groups. Results The diagnosis sensitivity, specificity, accuracy, positive predictive value and negative predictive value of EUS were 96.43 %, 82.5 %, 90.63 %, 88.52 % and 96.29 %. Early EUS scan with 72 h could identify the etiology of ABP and subsequent treatment based on the EUS can easily decrease the white blood cell count, percentage of neutrophils, total bilirubin and serum amylase (P < 0.05). The pain relief rate in EEI group after 1 week treatment was significantly higher than that in the DES group (87.50 % vs 66.67 %, P = 0.027) and average length of hospitalization was shorter [(12.70 ±2.10) d vs (14.10 ± 3.00) d, P = 0.006]. Delay EUS scan were likely to have higher white blood cell count and total bilirubin, meanwhile seemed to increase the organ failure rate and necrotic infection of the pancreas. Conclusion ABP with suspected obstructive jaundice should be considered to have endoscopy intervention. Results of EUS are the basis for treatment decision, which can avoid the unnecessary endoscopy treatment.

Objective: To develop a core information index system of disability for the elderly, which is suitable for the elderly in China and has educational and guiding significance and universal application value. Methods: The index system framework was established through an extensive literature review and expert discussions, and the index system was constructed by the Delphi expert consultation method. Results: A total of 74 experts (84 person-times)from various fields participated in the Delphi expert consultations.The positive coefficients of experts for the five rounds of expert consultations were 94.55%, 100.00%, 100.00%, 100.00% and 100.00%, respectively.The authoritative coefficients of experts ranged from 0.75 to 0.90.Based on the five rounds of Delphi expert surveys, the core information index system of disability for the elderly was composed of 16 indicators including health literacy of the elderly, nutritional status, musculoskeletal function, vaccination, prevention of falls, attention to mental health, social function, etc. Conclusions The core information index system of disability for the elderly is comprehensive, covering all components considered essential by a consensus from experts in various fields, and it is authoritative, extendable, scientific, influential, stable and popular.

Objective: To assess the effectiveness of interventions on patient trust Methods: A system review was conducted through searching 11 relevant databases, such as Cochrane Library, EMBASE, PsycINFO, CINAHL, PubMed, Web of Science, SinoMed, CNKI, WANFANG. The randomized controlled trials (RCTs) were screened from 1539 original studies according to inclusion and exclusion criteria Meta-analysis was used to evaluate and interpret the interventions. Results: Ten RCTs were included in the review. It was concluded from meta-analysis that no significant difference could be found between controlled and intervention groups by increasing doctors'abilities(SMD = -0.05, 95％ CI: -0.22 -0.12); while the other two interventions, doctor's information disclosure as well as patient education and nursing intervention, significantly enhanced patient trust (SMD = 0.13, 95％ CI: 0.06 - 0.21; SMD = 0.60, 95％ CI: 0.29 - 0.90). Conclusion: Doctor's information disclosure, patient education and nursing intervention are effective in increasing patients'trust, while intervention of doctor's ability promotion seems not so remarkable.

Objective To explore the effect of enhanced CT and enhanced MRI image fusion technique in making treatment decisions for primary liver cancer (PLC). Methods Clinical data of 55 patients with PLC who were treated in the Third Affiliated Hospital of Sun Yat-sen University between January 2013 and January 2015 were analyzed retrospectively. There were 42 males and 13 females, aged from 18-84 and with a median age of 52 years old. The informed consents of all patients were obtained and the local ethical committee approval was received. All the patients underwent enhanced CT and gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) enhanced MRI. CT and MRI images were fused by using flexible registration method based on finite element. Treatment decisions for these patients were discussed and made by HCC multidisciplinary consultation group. Discussion was conducted twice for each patient. The first discussion was based on enhanced CT images and the second was based on fused images. Changes of treatment decisions were observed and analyzed. Results Treatment decisions based on enhanced CT images included radical treatment in 8 cases, palliative surgical treatment in 35 cases and systemic medicine treatment in 12 cases. Treatment decisions based on fused images included radical treatment in 4 cases, palliative surgical treatment in 36 cases and systemic medicine treatment in 15 cases. Compared with those based on enhanced CT images, the conversion rate of radical treatment, palliative surgical treatment and systemic medicine treatment based on fused images was respectively 50%(4/8), 3%(1/35) and 25%(3/12). Conclusions Enhanced CT and Gd-EOB-DTPA enhanced MRI image fusion can change the treatment decisions for some patients with HCC, and it is of certain significance in optimizing the treatment protocols.

Objectives: This study explored the relationship between weight control and atrial fibrillation (AF) recurrence after catheter ablation in overweight and obese patients. Methods: We prospectively enrolled consecutive 333 overweight and obese patients aged 28 to 87 years old, who underwent catheter ablation for AF in Beijing Anzhen Hospital between October 2015 and February 2016. Data of patients′ characteristics, laboratory examination and treatment were collected at baseline. Each patient was followed up at 3, 6 and 12 months after ablation to collect information on weight, AF recurrence, stroke, major bleeding, hospitalization for cardiovascular reasons and death, etc. Patients were divided into weight controlled group (ΔBMI<-1 kg/m²) and weight uncontrolled group (ΔBMI≥-1 kg/m²), according to the changes in the most recent exposure BMI before AF recurrence in patients with recurrence or the BMI at 12 months′ follow-up in patients without recurrence and the BMI at baseline. Multivariate logistic regression was performed to adjust other known risk factors of AF recurrence and to explore the association between weight control and AF recurrence after catheter ablation. Results: There were 54 patients in weight controlled group and 279 patients in weight uncontrolled group. There were no significant differences in age, gender, education level, left atrial size and history of hypertension between the two groups (all P>0.05). The proportion of patients using angiotensin-converting enzyme inhibitors/angiotensin receptor blockers was higher in the weight controlled group (50.0%(27/54) vs. 34.8%(97/279), P=0.034). However, there was no significant difference in the proportion of patients with obesity (33.3% (18/54) vs. 29.7% (83/279)), paroxysmal AF (59.3% (32/54) vs. 56.6% (158/279)) and AF duration less than 5 years (76.9% (40/52) vs. 65.4% (178/272)) between the weight controlled group and the uncontrolled group. During 1-year follow-up after ablation, the recurrence rate of AF was significantly lower in the weight controlled group than that in the weight uncontrolled group (14.8% (8/54) vs. 32.6%(91/279), P=0.009). Multivariable logistic regression analysis shows that weight control is independently associated with a lower postoperative AF recurrence rate (OR=0.40, 95%CI 0.18-0.90, P=0.026). Conclusion Weight control is strongly associated with a lower AF recurrence rate after catheter ablation in overweight and obese patients.

Objective:To evaluate and analyze elderly health on the physical, psychological and social dimensions, so as to understand the health status and care needs of community-dwelling elderly residents.Methods:A cross-sectional study was carried out in the Meiyuan community, Malianwa Street, Haidian District of Beijing during July 22 to August 26, 2021.A total of 404 people aged 60 and above(70.6±8.6 years old)including 169 men and 235 women were enrolled through cluster sampling.All information about community-dwelling elderly residents was collected with face-to-face interviews and a standardized structured questionnaire for the evaluation and analysis of their physical, mental, social and overall health.Results:The rate of overall healthy residents was 21.3%(86), and the rates of physically, mentally and socially healthy residents were 66.8%(270), 86.6%(350) and 24.3%(98), respectively, in this community.There was a sex difference in social health in the whole group( χ2=9.008, P=0.011)and a higher proportion of men than women were considered generally healthy( χ2=8.963, P=0.003). People in the three age groups(224 in the 60-69 group, 109 in the 70-79 group and 71 in the ≥80 group)showed statistically significant differences in overall, physical, mental and social health( χ2=18.473, 61.186, 43.026 and 18.310, P<0.001), which declined with increasing age( χ2=13.172, 23.515, 26.806 and 10.068, P<0.001 or 0.01). Conclusions:s The overall healthy rate is not high among community-dwelling elderly residents in Beijing.The health status of the elderly gradually deteriorates with age.Health assessment for the elderly should be emphasized and targeted health education and prevention should be provided to promote disease prevention and mental health.

Objective:To evaluate and analyze the health status of elderly people from the physical, psychological and social aspects using the Health Criteria for Older Adults in China(2022), and to understand the impact of social demographic characteristics on the overall health status of the elderly.Methods:159 elderly people aged 60 years and over in the Lanyuan community of Malianwa Subdistrict, Haidian District, Beijing were selected by the stratified sampling method, with a mean age of(70.7±7.9)years, including 74 men and 85 women.The physical, psychological, social and overall health status of the elderly were comprehensively evaluated and analyzed from data collected through a self-designed questionnaire with face-to-face interviews at respondents' homes.Results:The percentage of participants in this community who were considered overall healthy was 30.2%(n=48). The proportions of those meeting the criteria for physical, mental and social health were 79.2%(n=126), 90.6%(n=144)and 32.1%(n=51), respectively.For participants of 3 age groups(60-69, n=89; 70-79, n=44; ≥80, n=26), differences in percentages of people who were considered not healthy, largely healthy and healthy, measured using the overall, physical, mental and social health criteria, were statistically significant( χ2=24.683, 57.096, 12.801, 11.802, all P<0.05), and results of the χ2test for trend showed that the frequency distribution of people with overall, physical, mental and social health decreased with age( χ2=16.878, 31.600, 9.626, 9.626, all P<0.05). Multivariate Logistic regression analysis showed that education level( OR=2.142, 95% CI: 1.053-4.538, P=0.035)was an influencing factor for overall health status of the elderly. Conclusions:The overall health status of community-dwelling elderly people in Beijing is relatively poor and deteriorates with age.Education level is a factor affecting their health status.Health assessment for the elderly should be strongly advocated, and targeted health education should be provided for the elderly in disease prevention and mental health care.
