Objective To study the effect of incorporating comprehensive geriatric assessment(CGA)into the whole-process WeChat-based case health management in elderly population who took annual physical examinations,thereby to improve their ability in health self-management.Methods A randomised controlled trial was conducted to select 100 elderly people who took annual physical examinations in our hospital from July 2022 to June 2023.The elderly were randomly divided into a control group and an trial group,with 50 people per group.CGA was applied to both groups,but the control group was under conventional health management,while the trial group received the incorporation of CGA into a whole-process WeChat-based case health management.The self-rated abilities for health practices scale(SRAHP)was used to compare the scores between the two groups before intervention,at 3,6 and 12 months after intervention.The scores of fatigue,resistance,ambulation,illnesses&loss of weight scale(FRAIL)and the mini nutritional assessment-short form(MNA-SF)were compared between the two groups before intervention and at 12 months after intervention.Incidence of falls was also evaluated after intervention.Results All the participants completed the study.Repeated measures analysis of variance showed that total SRAHP scores had statistical significances in main effect on time,group and interaction(Ftime=193.451,P<0.001;Fgroup=23.661,P<0.001;Finteraction=29.970,P<0.001).Further analysis revealed that the elderly in trial group had higher total scores in SRAHP than those in the control group at 6 and 12 months after intervention(both P<0.001).At 12 months after intervention,the trial group showed better scores in FRAIL and MNA-SF than the control group(both P<0.05)as well as with a lower incidence of falls(P<0.05).Conclusion Incorporation of CGA into a comprehensive WeChat-based case health management,over a long-term,can effectively enhance the ability in health self-management among elderly individuals who take annual health examinations,improve frailty and nutritional status and reduce the incidence of falls.The health self-management discovered from this study provides a valuable reference for health management among the elderly people who take annual physical examinations.

Objective:To investigate the efficacy of laparoscopic treatment of gangrenous appendicitis at the base using barbed wire for closure of the residual appendiceal stump.Methods:A case-control study was conducted among 58 patients with acute gangrenous appendicitis at the base who were admitted to the Department of General Surgery at Fujian Tingzhou Hospital from January 2018 to December 2022. Based on the type of suture used for burying the residual appendiceal stump during the procedure, the patients were divided into two groups: the control group ( n = 28, intermittent full-thickness suture embedding of the appendiceal stump using absorbable sutures) and the observation group ( n = 30, continuous full-thickness suture embedding of the appendiceal stump using barbed sutures). Intraoperative and postoperative related indicators, as well as the incidence of postoperative complications, were compared between the two groups. Results:In the observation group, the time for closure of the residual stump was (4.17 ± 0.66) minutes, which was significantly shorter than that in the control group ( t = 10.98, P < 0.001). The rate of conversion rate to open surgery in the observation group was significantly lower than that in the control group [3.33% (1/30) vs. 21.42% (6/28), χ 2 = 15.13, P < 0.001]. The recovery time of gastrointestinal function and the length of hospital stay in the observation group were (39.40 ± 8.10) hours and (4.33 ± 0.80) days, respectively, which were significantly shorter than those in the control group [(65.70 ± 11.30) hours, (6.11 ± 1.13) days, t = 10.26, 6.92, both P < 0.001]. Conclusion:The use of barbed wire sutures for burying the appendiceal stump in laparoscopic surgery for gangrenous/perforated appendicitis at the base effectively shortens the closure time of the stump, reduces the conversion rate to open surgery, minimizes postoperative complications, and shortens the length of hospital stay, making it a valuable technique for promotion in primary care hospitals.

Background Studies on the association between greenness exposure and allergic rhinitis (AR) in children are mostly conducted in developed countries, and the conclusion is not consistent. Objective Using street view data to explore the association between greenness exposure and allergic rhinitis (AR) prevalence in Chinese children. Methods A cross-sectional study was conducted among 40868 children aged 2-17 years in three cities of Northeast China from 2012 to 2013, which consisted of 20886 (51.1%) boys and 19982 (48.9%) girls. The information of AR prevalence was obtained through questionnaire. Based on downloaded street view images from Tencent Maps, a green view index (GVI) of green vegetation (trees and grass) within 800 m and 1000 m buffer of the participants' schools was calculated by using artificial intelligence, and it was used as a surrogate of the greenness exposure. A mixed-effect logistic regression model was used to estimate the odds ratio (OR) of AR prevalence in children for per increase of inter-quartile range (IQR) of GVI. In addition, according to ambient PM_2.5 concentration, the participants were divided into a low PM_2.5 exposure group (≤56.23 μg·m⁻³) and a high exposure group (>56.23 μg·m⁻³) to investigate whether PM_2.5 was a modifier on the association between GVI and AR. Results The average age of the subjects was (10.40±3.68) years and 3 963 (9.7%) subjects reported diagnosed AR. Within 800 m buffer, an IQR increase in GVI for trees (IQR=0.031, OR=0.85, 95%CI: 0.81-0.90) and overall greenness (IQR=0.029, OR=0.86, 95%CI: 0.81-0.90) was associated with lower adjusted odds ratio of AR. The interaction between PM_2.5 and GVI was statistically significant (P< 0.1), that is, the negative associations of trees and overall greenness with AR were observed only at low PM_2.5 exposure levels. The sensitivity analysis results of GVI within 1000 m buffer was consistent with that within 800 m buffer. Conclusion Exposure to green vegetation, especially trees, may be associated with decreased risks of AR in children, and such associations may be more obvious in areas with a low PM_2.5 concentration.

Objective To identify the expression of sphingosine-1-phosphate receptor (S1PR) subtypes, C-myc and His tag proteins of human umbilical vein endothelial fusion cell line, EA.hy926 and human umbilical vein endothelial cells (HUVEC), CRL-1730 for studying the function of apolipoprotein M (ApoM)-S1P axis. Methods Two kinds of cells (EA. hy926 and CRL-1730) were cultured to reach the density of 60%-70% in vitro. Immunofluorescence technique was em?ployed to investigate the expressions of coagulation factorⅧ(FⅧ), ApoM, S1PR1-S1PR5, C-myc and His tag proteins. Re?sults (1) Two kinds of cells both expressed FⅧand ApoM. FⅧpresented scattered particle distribution in CRL-1730, while uniform distribution in EA.hy926. However, ApoM was strongly expressed and widely distributed in cytoplasm of two kinds of cells. (2) S1PR1-3 can be detected on their membrane other than S1PR4 and S1PR5. S1PR1 was highly expressed but S1PR2 and S1PR3 were in a low level expression. (3) Two kinds of cells both expressed C-myc and His tag proteins in cytoplasm. Conclusion Two kinds of cells have the properties of endothelial cells and can express FⅧ, ApoM, C-myc and His tag proteins. It is not suitable for choosing C-myc and/or His tag–conjugated recombinant ApoM to study the fuction of ApoM-S1P axis with these two kinds of cells.
