AIM: To investigate the efficacy of Yangyin Yiqi Decoction combined with polyethylene glycol eye drops on dry eye disease after cataract surgery and its effect on inflammatory factors in tears.METHODS:Prospective study. A total of 104 patients(104 eyes)with dry eye disease after cataract surgery admitted to our hospital from April 2022 to March 2024 were selected and randomly divided into two groups: 52 cases(52 eyes)in the control group were treated with polyethylene glycol eye drops; 52 cases(52 eyes)in the combined group were treated with Yangyin Yiqi Decoction combined with polyethylene glycol eye drops. The dry eye symptom score, tear film stability index, tear inflammatory factor level, ocular surface disease index score(OSDI)and clinical efficacy of the two groups were compared before and after treatment.RESULTS:There were 6 cases(6 eyes)lost to follow-up, and 3 cases(3 eyes)were lost to follow-up in each group, with a loss to follow-up rate of 5.8%. The total effective rate of treatment in the combination group was significantly higher than that in the control group(94% vs 80%, P=0.037), and the Schirmer I test(SIt)and tear film break-up time(BUT)were higher than those in the control group(all P<0.05), and the dry eye symptom score, corneal fluorescein staining(FL)score, IL-1β, TNF-α, hs-CRP levels in tears and OSDI score were lower than those in the control group(all P<0.05).CONCLUSION:The combination of Yangyin Yiqi Decoction and polyethylene glycol eye drops provides an effective treatment plan for patients with dry eye disease after cataract surgery. It can effectively alleviate dry eye symptoms, reduce eye discomfort, improve tear film stability and ocular surface status, and reduce inflammatory factors in tears.

Objective To explore the occurrence and influencing factors of MODS in elderly pa-tients with SAH.Methods A retrospective analysis was conducted on 187 elderly SAH patients admitted in the Second Affiliated Hospital of Guizhou Medical University from January 2021 to June 2024.According to the presence or absence of MODS,they were divided into MODS group(81 cases)and non-MODS group(106 cases).Their general clinical data were compared between the two groups.Multivariate logistic regression analysis was used to identify the risk factors for MODS in elderly SHA patients.ROC curve analysis was applied to evaluate the predictive value of the major risk factors for MODS in the patients.Results The MODS group had significantly ad-vanced age,larger proportion of modified Fisher grades Ⅲ—Ⅳ,higher APACHE Ⅱ score,and in-creased FPG level than the non-MODS group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that APACHE Ⅱ score(OR=1.108,95％CI:1.070-1.148,P=0.000)and mo-dified Fisher grade(OR=1.143,95％CI:1.095-1.194,P=0.000)were independent risk factors for MODS in elderly SAH patients.ROC curve analysis suggested that the AUC value of APACHE Ⅱ score,modified Fisher grade and their combination in predicting the occurrence of MODS in elderly SAH patients was 0.809,0.737 and 0.880,respectively,with a sensitivity of 59.35％,88.93％and 84.02％,and a specificity of 88.73％,58.52％and 81.15％,respectively.The combined detection showed better predictive performance than the indicator alone(P＜0.01).Con-clusion The incidence of MODS is quite high in elderly patients with SAH.APACHE Ⅱ score and modified Fisher grade are the main risk factors affecting the occurrence of MODS.

Objective To analyze the feasibility of probiotics in delaying the progression of early Alzheimer's disease(AD)based on the changes of brain-gut-microbiota axis factors.Methods A total of 100 patients with early AD who visited Shaoxing 7th People's Hospital from December 2023 to December 2024 were selected and divided into control group(40 cases)and study group(60 cases)based on different treatment methods.The control group was treated with donepezil hydrochloride,while study group was treated with donepezil hydrochloride combined with probiotic preparations.The cognitive function,daily living ability,intestinal flora,and relative expression levels of brain-gut-microbiota axis factors,interleukin(IL)-6,tumor necrosis factor-α(TNF-α),5-hydroxytryptamine(5-HT),γ-aminobutyric acid(GABA),and lipopolysaccharide(LPS)/Toll-like receptor 4(TLR4)/nuclear factor-KB(NF-κB)axis factors were compared before and after treatment in both groups.The clinical efficacy and prognosis monitoring results were also compared.Results The total effective rate and the proportion of patients with a clinical dementia rating score of 0 in study group were higher than those in control group(P＜0.05).The cognitive function and daily living ability scores in study group were higher than those in control group(P＜0.05).The copy numbers of lactobacillus and bifidobacterium in study group were higher than those in control group,while the copy numbers of enterococcus and escherichia coli were lower(P＜0.05).The relative expression levels of amyloid-β protein 1-42,IL-6,TNF-α,TLR4,and NF-κB in study group were lower than those in control group,and the levels of 5-HT and GABA were higher(P＜0.05).Conclusion Probiotics can delay the progression of early AD patients and improve clinical efficacy.It is speculated that the mechanism of action may be related to regulating the brain-gut-microbiota axis-mediated LPS/TLR4/NF-κB pathway to restore the intestinal microecology and alleviate neurological inflammation.

Objective To explore the diagnosis and treatment strategies for elderly patients with ground-glass opacity (GGO). Methods The imaging features and postoperative pathological findings of the elderly patients with pulmonary GGO receiving surgery in our hospital from 2017 to 2019 were retrospectively analyzed. The patients were divided into an elderly patient group and a non-elderly patient group based on their age. Results Finally 575 patients were included in the study. There were 281 elderly patients, including 83 males and 198 females, with an average age of (67.0±5.3) years. There were 294 non-elderly patients, including 88 males and 206 females, with an average age of (49.1±7.3) years. Compared with the non-elderly patients, elderly GGO patients showed the following distinct clinical features: long observation time for lesions (P=0.001), high proportion of rough edges of GGO (P<0.001), significant pleural signs (P＜0.001) and bronchial signs (P＜0.001), and high proportion of type Ⅱ-Ⅳ GGO (P<0.001), lobectomy type (P=0.013), and invasive lesions reported in postoperative pathology (P<0.001). There was no statistical difference in the average hospital stay between the two groups (P=0.106). Multivariate logistic regression analysis showed that GGO diameter and GGO type were the main factors affecting the operation. Observation time, GGO diameter, GGO type and pleural signs were the main influencing factors for postoperative pathological infiltrative lesions. The cut-off value of GGO diameter in predicting infiltrating lesions was 10.5 mm in the elderly patients group. Conclusion The size and type of GGO are important factors in predicting invasive lesions and selecting surgical methods. Elderly patients with radiographic manifestations of type Ⅱ-Ⅳ GGO lesions with a diameter greater than 10.5 mm should be closely followed up.

Objective: To investigate the spatio-temporal clustering characteristics of influenza in Ningxia Hui Autonomous Region from 2014 to 2023, so as to provide the basis for strengthening influenza prevention and control. Methods: Data pertaining to influenza cases reported in Ningxia Hui Autonomous Region from 2014 to 2023 were retrieved from the Infectious Disease Surveillance System of the Chinese Disease Prevention and Control Information System, including age, sex, current residence, onset date, and reporting date. The seasonal incidence of influenza was analyzed using seasonal index. The spatio-temporal clustering characteristics of influenza were identified using spatial autocorrelation analysis and spatio-temporal scan analysis. Results: A total of 20 377 influenza cases were reported in Ningxia Hui Autonomous Region from 2014 to 2023, with a male-to-female ratio of 1.15∶1. The majority were children under 15 years, with 10 950 cases accounting for 53.74%. Influenza was highly prevalent in January, February, March, and December, with seasonal indices of 219.06%, 111.00%, 246.65%, and 366.24%, respectively. The average annual reported incidence was 29.55/100 000, among which Pengyang County, Jinfeng District, Dawukou District, Xiji County, and Litong District had higher average annual reported incidence, at 63.99/100 000, 55.71/100 000, 55.70/100 000, 49.49/100 000, and 49.04/100 000, respectively. Spatial autocorrelation analysis showed that in 2023, there was spatial clustering of influenza cases in Ningxia Hui Autonomous Region (Moran's I=0.333, P<0.05), with a high-high cluster in Jingyuan County, while in other years, the distribution of influenza cases was random (all P>0.05). Spatio-temporal scan analysis showed that from 2014 to 2023, there were four space-time clusters in Ningxia Hui Autonomous Region, including one type Ⅰ cluster in Hongsibao District of Wuzhong City, with the clustering period from January 20 to 26, 2014; and three type Ⅱ clusters, mainly in January, February, March and December, covering one area in Shizuishan City, five areas in Guyuan City, one area in Zhongwei City, three areas in Wuzhong City, and four areas in Yinchuan City. Conclusions From 2014 to 2023, children under 15 years were the primary population affected by influenza in Ningxia Hui Autonomous Region, with distinct spatio-temporal distribution characteristics. The peak incidence occurred during the winter and spring seasons, and the main clustering areas were in the southern regions.

Objective To investigate the current status and barriers to implementing non-accompanied care services in medical institutions in Zhejiang Province,and to provide a basis for the improvement of standardized management of such services.Methods A self-designed questionnaire was conducted from September to October 2024 among all secondary and tertiary medical institutions in Zhejiang Province to assess the implementation status and barriers to non-accompanied care services.Results A total of 397 questionnaires were distributed,with 389 valid responses,yielding a valid response rate of 97.98％.Non-accompanied care services were implemented in 118 institutions(30.33％).Among these,90 institutions(76.27％)had established management systems for non-accompanied wards;71 institutions(60.17％)had a medical nursing assistant-to-bed ratio lower than 1∶5;41 institu-tions(34.75％)provided tiered training for medical nursing assistants;93 institutions(78.81％)required patients to bear the full cost of the service.Compared with secondary medical institutions,tertiary medical institutions have more complete management system for non-accompanied care services.The main obstacles hindering the development of non-accompanied care services include an imperfect management system for non-accompanied wards,a shortage of medical nursing assistants,a lack of standardized training for such assistants,inconsistent charging standards,and low acceptance among patients and their families.Conclusion The promotion of non-accompanied care services in medical institutions in Zhejiang Province has achieved initial success.However,challenges persist,including incomplete management systems,uneven development across hospital tiers,and imperfect charging mechanisms.It is recommended that relevant authorities strengthen policy support,enhance standardized training for healthcare nursing assistants,refine cost-sharing mechanisms,and improve the quality and sustainability of non-accompanied care services through multi-party collaboration.

Objective This study aims to develop an early in-hospital temperature management protocol for heat stroke patients and assess its effectiveness,providing guidance for rapid cooling and precise target temperature control.Methods The protocol was developed through a Delphi expert consultation combined with expert panel meetings.A multi-center,non-randomized,historical control study was conducted,utilizing convenience sampling to select heat stroke patients from the emergency departments of 7 tertiary hospitals in Zhejiang Province,China,between June and August 2024 as an experimental group.The protocol was implemented in this group,while the control group consisted of heat stroke patients treated between June and August 2022,prior to protocol implementation.Cooling rates,target temperature attainment rates,and clinical outcomes were compared between the 2 groups.Results The final protocol included 6 primary indicators,23 secondary indicators,and 56 tertiary indicators.After protocol implementation,the experimental group achieved a cooling rate of 0.08(0.05～0.09)℃/min within 0.5 hours,significantly higher than the control group,which had a rate of 0.04(0.02～0.06)℃/min(P＜0.001).The target temperature attainment rates at 0.5 hours and 2.0 hours were 55.93％and 98.31％,respectively,significantly higher than the rates of 15.87％and 61.11％in the control group(P＜0.001).The mechanical ventilation rate,hospitalization rate,ICU admission rate,and mortality rate in the experimental group were 25.42％,61.02％,44.07％,and 8.47％,respectively.Logistic regression analysis revealed that the early in-hospital temperature management protocol significantly reduced the risk of mechanical ventilation and hospitalization in heat stroke patients,with odds ratios(ORs)of 0.294 and 0.300,respectively(both P＜0.05).Conclusion The developed protocol for early in-hospital temperature management in heat stroke patients is scientific,systematic,and practical.It improves cooling rates and target temperature attainment,thereby enhancing the prognosis of heat stroke patients.
