Objective: To analyze the characteristics of alcohol poisoning cases among minors receiving pre hospital 120 emergency services in Zhengzhou, providing evidence for regional management strategies of alcohol poisoning among minors. Methods: A retrospective study was conducted on 1 630 alcohol poisoning cases (aged 0-18 years) from Zhengzhou s 120 emergency system during 2017-2019 and 2023. Data on gender, age, occurrence timeframes were analyzed using t-test and χ 2 test for intergroup comparisons. Results: Annual cases were 291 (2017), 353 (2018), 483 (2019), and 503 (2023). Compared with 2017, male alcohol poisoning cases increased by 66.94% while female cases surged 104.35% by 2023. The peak incidence of alcohol poisoning among minors occurred among 16-18 year olds (85.40%), followed by 13-15 year olds (13.74%). Most cases clustered between 21:01-03:00 (60.43%), with male cases peaking at 22:01-23:00 (12.73%) and female cases peaking at 02:01-03:00 ( 11.25 %). Between 00:01-03:00, male cases progressively decreased while female cases increased. Severity distribution showed 355 mild cases (21.78%), 1 035 moderate cases (63.50%), and 240 severe cases (14.72%). Conclusions Zhengzhou region has experienced sustained growth in underage alcohol poisoning cases, predominantly occurring from evening to early morning with moderate severity, female cases demonstrate faster growth rates. Multifaceted regulatory measures should be implemented to strengthen supervision of underage drinking behaviors.

The randomized controlled trials (RCTs) regarding acupuncture direction published from January 1st, 2013, to November 7th, 2023 were searched in China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, and VIP Chinese Journal Database. As a result, 21 RCTs were included. The problems identified included conceptual misunderstandings regarding acupuncture direction, incomplete selection strategies, confounding research factors, and inaccuracies in reporting. Based on the findings, four strategic approaches for enhancing therapeutic efficacy through acupuncture direction were summarized: aligning needle direction with the meridian pathway, directing the needle toward the lesion site, orienting the needle toward adjacent acupoints, and targeting special anatomical structures. Two additional strategies were proposed for optimizing the procedure: simplifying acupuncture operations and directing the needle toward safe anatomical sites. Recommendations were made to improve the rationality of research factor settings and the completeness of acupuncture operation reporting. Furthermore, three methods for reporting acupuncture direction were discussed: reporting the tip-pointed position, reporting the insertion angle and orientation, and reporting azimuth and polar angles, aiming to promote greater standardization and completeness in acupuncture practice and reporting.

Objective:To explore the policy synergy of 71 Diagnosis-Intervention Packet(DIP)pilot cities from the perspective of policy synergy at both the national and provincial levels.Methods:Policy evaluation dimensions were constructed by text mining method,and the surface plots of policy consistency were drawn by the Policy Modeling Consistency Index(PMC),and the degree of policy synergy between each city and national policies and with cities in the province were calculated by correlation analysis.Results:Different levels of policy in pilot cities and the policy differences among pilot cities mainly focus on policy disclosure,core elements,and infrastructure,at the central level,most cities maintain a high degree of consistency with the state in terms of policy nature,management measures,infrastructure,and policy evaluation,and the policy timeliness,policy perspective,and core elements still need to be improved;at the provincial level,cities within the 20 provinces show characteristics in low level of complete synergy,high level of close synergy and differentiated partial synergy.Conclusion:The 71 DIP pilot cities have established a preliminary policy system,but there are still more cities with missing policies and a lack of coordination.In the future,efforts should be made to advance the policy development process,promote the improvement of the policy system,and promote coordination among pilot cities in policy implementation.

Objective:To analyze the concentration of formic acid,propionic acid and butyric acid in gingival crevicular fluid(GCF)of patients with stages Ⅲ and Ⅳ periodontitis,and their relationship with periodontitis.Methods:The study enrolled 37 systemically healthy patients with periodontitis and 19 healthy controls who visited Department of Periodontology,Peking University School and Hospital of Sto-matology from February 2008 to May 2011.Their GCFs were collected from the mesial-buccal site of one molar or incisor in each quadrant.Periodontal clinical parameters,including plaque index(PLI),probing depth(PD),bleeding index(BI),and attachment loss(AL).Concentrations of formic acid,propionic acid and butyric acid in the supernatant of the GCFs were analyzed by high-performance capil-lary electrophoresis(HPCE).The prediction ability of formic acid,propionic acid and butyric acid with the risk of periodontitis and the differences between grade B and grade C periodontitis were analyzed.Results:In this study,32 patients with stage Ⅲ and 5 patients with stage Ⅳ were enrolled,including 9 patients with grade B and 28 patients with grade C.Clinical periodontal variables in the patients with pe-riodontitis were significantly higher than those in the control group(P＜0.001).Formic acid was signifi-cantly lower in periodontitis than that in the control group[5.37(3.39,8.49)mmol/L vs.12.29(8.35,16.57)mmol/L,P＜0.001].Propionic acid and butyric acid in periodontitis were significantly higher than those in the control group:Propionic acid,10.23(4.28,14.90)mmol/L vs.2.71(0.00,4.25)mmol/L,P＜0.001;butyric acid,2.63(0.47,3.81)mmol/L vs.0.00(0.00,0.24)mmol/L,P＜0.001.There was no significant difference in formic acid,propionic acid and butyric acid concentrations between grade B and grade C periodontitis(P＞0.05).Propionic acid and butyric acid in the deep pocket were significantly higher than in the shallow pocket,while the concentration of formic acid decreased with the increase of PD.Propionic acid(OR=1.51,95％CI:1.29-1.75)and butyric acid(OR=3.72,95％CI:1.93-7.17)were risk factors for periodontitis,while formic acid(OR=0.87,95％CI:0.81-0.93)might be a protective factor for periodontitis.Propionic acid(AUC=0.852,95％CI:0.805-0.900),butyric acid(AUC=0.889,95％CI:0.841-0.937),f(formic acid,AUC=0.844,95％CI:0.793-0.895)demonstrated a good predictive capacity for the risk of periodontitis.Conclusion:The concentration of formic acid decrease in the GCF of periodontitis patients,which is a protective factor for periodontitis,its reciprocal have good predictive capacity.However,propionic acid and butyric acid increase,which are risk factors for periodontitis and have good predictive capacity.The concentration of formic acid,propionic acid,and butyric acid vary with probing depth,but there is no significant difference between grade B and grade C periodontitis.
