ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

ObjectiveTo establish a high-performance liquid chromatography（HPLC） for the quantitative analysis of multiple components in Gegen Qinlian tablets， and to comprehensively evaluate the quality of samples from different manufacturers by integrating chemical pattern recognition and technique for order preference by similarity to ideal solution（TOPSIS）， in order to provide a reference basis for quality evaluation and control of Gegen Qinlian tablets. MethodsHPLC was employed to determine the contents of 10 components in 28 batches of Gegen Qinlian tablets collected from 6 manufacturers， and taking the detection results as variables， SIMCA 14.1 and SPSS 26.0 were employed for cluster analysis（CA）， principal component analysis（PCA）， and orthogonal partial least squares-discriminant analysis（OPLS-DA） to identify key components affecting the quality. Then， TOPSIS analysis was employed to rank the quality of Gegen Qinlian tablets from the 6 manufacturers and establish a comprehensive quality evaluation method. ResultsA quantitative method for Gegen Qinlian tablets was established. After methodological validation， the method was found to be stable and reliable， and could be used for the quantitative analysis of this preparation. The contents of 3′-hydroxy puerarin， puerarin， 3′-methoxy puerarin， daidzein， coptisine hydrochloride， epiberberine， jatrorrhizine hydrochloride， berberine hydrochloride， palmatine hydrochloride and baicalin in 28 batches of samples were 3.58-7.35， 24.88-42.32， 4.20-9.36， 4.33-7.60， 2.52-6.44， 0.93-4.10， 0.58-3.05， 10.68-22.92， 0.82-4.82， 11.73-60.16 mg·g^-1， respectively. Among them， puerarin， berberine hydrochloride and baicalin all met the limit requirements for this preparation specified in the 2025 edition of the Pharmacopoeia of the People's Republic of China. CA and PCA clustered the 28 batches of samples into 5 categories， PCA extracted 2 principal components with a cumulative variance contribution rate of 90.588%， and OPLS-DA screened out 4 differential markers with variable importance in the projection（VIP） values>1.0， namely baicalin， 3′-hydroxy puerarin， coptisine hydrochloride and palmatine hydrochloride， which might be the main components affecting the quality of Gegen Qinlian tablets. TOPSIS analysis showed that the comprehensive score of each evaluation index（C_i） values of different manufacturers were different. Among them， the C_i of manufacturer B was ranked higher， indicating potentially superior quality， while the C_i of manufacturer A was ranked lower， suggesting potentially inferior quality. ConclusionThis study establishes a quantitative method for Gegen Qinlian tablets， and the content uniformity of the same manufacturer is good， while there are differences in the contents of active components among different manufacturers. Through the chemical pattern recognition analysis， it is found that the content differences of Gegen Qinlian tablets may be related to baicalin， 3′-hydroxy puerarin， coptisine hydrochloride and palmatine hydrochloride.

The quantitative results showed that the mass fractions of coclaurine， magnoflorine， coptisine hydrochloride， epiberberine， jatrorrhizine hydrochloride， spinosin， berberine hydrochloride， palmatine hydrochloride， 6"'-feruloylspinosin， and jujuboside A in the 12 batches of samples were 0.044-0.091， 0.908-1.698， 0.325-0.549， 0.163-0.287， 0.103-0.172， 0.712-0.952， 1.185-1.843， 0.341-0.598， 0.228-0.405， and 0.050-0.091 mg/g， respectively. CONCLUSIONS The established HPLC fingerprint and multi-component determination method is stable and reliable， and can provide a basis for the quality standard formulation and clinical application of Z. jujuba stir-fried with C. chinensis juice.

ObjectiveTo investigate the antiviral efficacy of pegylated interferon α-2b （PEG-IFN-α-2b） in patients with HBV-related liver cirrhosis， to assess the safety and tolerability of this regimen， and to provide evidence-based medical evidence for optimizing the treatment strategies for patients with HBV-related compensated liver cirrhosis. MethodsA prospective study was conducted among 115 patients with HBV-related compensated liver cirrhosis and 114 patients with CHB who attended Third People’s Hospital of Taiyuan from January 2023 to March 2024. Treatment-naïve patients received PEG-IFN-α-2b monotherapy， while the patients once treated with nucleos（t）ide analogues （NAs） received PEG-IFN-α-2b add-on therapy. The patients with HBV-related compensated liver cirrhosis were followed up at baseline and at 12， 24， 36， and 48 weeks of treatment. Samples were collected from CHB patients at baseline and at the end of follow-up to assess virological indicators， routine blood test results， and liver function. The chi-square test was used for comparison of categorical data between groups； the independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the one-way repeated measures analysis of variance was used for comparison among different time ponts within the same group，and the Bonferroni was applied for post-hoc pairwise comparisons； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Friedman test was used for comparison across different time points within the same group， and the Nemenyi test was utilized for subsequent pairwise comparisons. The multivariate stepwise Logistic regression analysis was used to investigate the influencing factors for clinical cure. ResultsCompared with the CHB group， the HBV-related compensated liver cirrhosis group had a significantly higher mean age （43.50±9.97 years vs 40.90±8.16 years， t=2.160， P=0.032）， a significantly higher proportion of patients with hepatitis B e antigen at baseline （28.70% vs 15.79%， χ²=4.788， P=0.029）， and a significantly lower platelet level ［（178.67±55.07）×10⁹/L vs （194.93±55.79）×10⁹/L， t=2.217， P=0.028］. Compared with the CHB group at the end of follow-up， the HBV-related compensated liver cirrhosis group had significantly lower HBV surface antigen （HBsAg） clearance rate （10.38% vs 33.04%， χ²=14.988， P<0.001） and HBV surface antibody positive rate （0.00% vs 19.64%， χ²=21.041， P<0.001）. Compared with the CHB group at the end of follow-up，the HBV-related compensated liver cirrhosis group had significantly lower aminotransferase levels ［ALT： 31.00（19.00～47.50） U/L vs 40.00（27.00～57.00） U/L， Z=2.433， P<0.05； AST： 31.00（23.00～45.50） U/L vs 37.00（25.00～52.00） U/L， Z=1.963， P<0.05］， but significantly higher level of white blood cells （WBC） ［（4.02±1.56）×10⁹/L vs （3.59±1.24）×10⁹/L， t=2.272， P<0.05］， neutrophils ［（2.39±1.17）×10⁹/L vs （1.87±0.94）×10⁹/L， t=3.284， P<0.05］， and platelets ［（143.93±68.10）×10⁹/L vs （121.88±49.72）×10⁹/L， t=2.588， P<0.05］. A lower level of HBsAg （OR=0.997， 95%CI： 0.996　—　0.999， P<0.001） and previous treatment with NAs （OR=5.889， 95%CI： 2.195　—　17.330， P<0.001） were positive predictive factors for clinical cure， while liver cirrhosis （OR=0.177， 95%CI： 0.063　—　0.470， P<0.001） was a negative predictive factor for clinical cure. During follow-up， no patients experienced acute decompensation or progression to hepatocellular carcinoma， and the main adverse events included fever， fatigue， reductions in WBC and platelets， weight loss， alopecia， and thyroid dysfunction. In the subgroup analysis of HBV-related compensated liver cirrhosis， in both the treatment-naïve patients and the patients previously treated with NAs， there was a significant reduction in HBsAg level from baseline to week 36 of treatment ［treatment-naïve： 99.25 （5.87　—　1 212.35） IU/mL vs 403.47 （36.94　—　2 569.02） IU/mL， P<0.05； previously treated with NAs： 205.94 （14.00　—　737.80） IU/mL vs 427.03 （65.64　—　1 552.65） IU/mL， P<0.05］ and week 48 of treatment ［treatment-naïve： 85.45 （0.58　—　827.56） IU/mL vs 403.47 （36.94　—　2 569.02） IU/mL， P<0.05； previously treated with NAs： 45.28 （0.16　—　267.27） IU/mL vs 427.03 （65.64　—　1 552.65） IU/mL， P<0.05］. There were significant increases in the levels of aminotransferases during treatment， as well as significant reductions in the levels of WBC， neutrophils， platelets， and hemoglobin （all P<0.05）. ConclusionAlthough a finite course of PEG-IFN-α-2b therapy has achieved a relatively low rate of clinical cure in the treatment of HBV-related compensated liver cirrhosis， it can still significantly reduce the level of HBsAg， and this treatment regimen has good safety and tolerability， without accelerating disease progression.

ObjectiveTo evaluate the clinical efficacy of acupuncture in the treatment of adolescent depression and to explore its potential mechanisms based on functional magnetic resonance imaging （fMRI） and serum proteomics. MethodsA randomized， double-blind， sham acupuncture-controlled trial design was conducted. A total of 100 adolescents with depression were enrolled and randomly assigned to an acupuncture group and a sham acupuncture group， with 50 participants in each group. In addition， 20 healthy subjects were recruited as healthy controls. Participants in the acupuncture group received acupuncture at Baihui （GV 20）， Yintang （GV 29）， Zhongwan （CV 12）， Qihai （CV 6）， bilateral Tianshu （ST 25）， bilateral Neiguan （PC 6）， bilateral Zusanli （ST 36）， and bilateral Taichong （LR3）. The sham acupuncture group received intervention using a blunt placebo needle without skin penetration. Both groups received 30-min treatments three times per week for 4 weeks. The primary outcome was the reduction rate of the 24-item Hamilton Depression Rating Scale （HAMD-24） score. Secondary outcomes included changes in HAMD-24 scores before and after treatment， covering nine factors （anxiety/somatization， cognitive impairment， sleep disturbance， psychomotor retardation， hopelessness， fatigue， weight change， diurnal mood variation， and suicidal ideation）， response rate and remission rate after treatment， and symptom severity before and after treatment. Subgroup analyses of total HAMD-24 scores were performed according to concomitant medication use and the number of medications taken. During the study period， all adverse events were monitored and recorded to evaluate safety. Patients who volunteered and met the eligibility criteria for imaging examinations were selected to undergo brain fMRI scanning and serum proteomic analysis to investigate changes in functional connectivity among brain regions and differential proteins. ResultsA total of 49 participants in the acupuncture group and 50 participants in the sham acupuncture group were included in the efficacy analysis. Among them， 20 participants in the acupuncture group and 21 in the sham acupuncture group completed fMRI scans， while 19 participants in the acupuncture group and 21 in the sham acupuncture group completed serum proteomic analyses. After 4 weeks of treatment， the mean reduction rate of HAMD-24 score in the acupuncture group was significantly higher than that in the sham acupuncture group ［（58±24）% vs.（26±19）%， P＜0.01］. Compared to baseline， scores for anxiety/somatization， cognitive impairment， psychomotor retardation， and hopelessness， and the total HAMD-24 score significantly decreased in both groups. In addition， the acupuncture group showed significant reductions in sleep disturbance， fatigue， and suicidal ideation scores （P＜0.01）. After treatment， the response rate and remission rate were 67.35% （33/49） and 24.48% （12/49） in the acupuncture group， respectively， significantly higher than 6.00% （3/50） and 0 in the sham acupuncture group （P＜0.01）. The proportion of participants with moderate symptoms was lower， whereas the proportion with mild symptoms was higher in the acupuncture group than the sham acupuncture group （P＜0.01）. Among those receiving acupuncture alone， acupuncture combined with medication， or fewer than three medications， the total HAMD-24 scores decreased after treatment in both the acupuncture subgroup and the sham acupuncture subgroup， with significantly lower scores in the acupuncture subgroup （P＜0.01）. During the study period， four mild adverse events were reported， including one case in the acupuncture group and three cases in the sham acupuncture group； none of these events affected the continuation of treatment. fMRI results showed that acupuncture enhanced functional connectivity between the prefrontal cortex and cerebellar-limbic system-related brain regions. Proteomic analysis identified 24 differentially expressed proteins associated with acupuncture treatment， mainly enriched in pathways related to neuroinflammation and energy metabolism. ConclusionAcupuncture can significantly improve depressive symptoms in adolescents with depression. Its therapeutic effects may be achieved by modulating emotion-related brain networks and regulating pathways associated with neuroinflammation and energy metabolism.

Objective To understand the surveillance situation of poliovirus in Guangzhou from 2011 to 2024, and to further strengthen polio surveillance and ensure the continued maintenance of a polio-free status. Methods An analysis was conducted on the discovery and investigation results of six cases of vaccine-derived poliovirus (VDPV) detected in Guangzhou. Results A total of 6 VDPV incidents were reported in Guangzhou from 2011 to June 2024, among which 5 incidents were from sewage sample testing in the Liede Sewage Treatment Plant in Guangzhou, all of which were confirmed as VDPV, with 1 for type I, 1 for type II, and 3 for type III. In addition, one confirmed HFMD case was identified as a type VDPV II carrier. No presence of any wild poliovirus (WPV), VDPV cases, or circulating VDPV (cVDPV) was reported. Conclusion Guangzhou City has maintained a high level of vigilance and effectiveness in the monitoring and prevention of polio. Continuously strengthening the construction of the polio monitoring network, optimizing vaccination strategies, and comprehensively improving public health awareness are still the focus of the prevention and control work in the future.

Objective To develop a toolkit suitable for assisting community health institutions in the early identification and inter-vention of mild cognitive impairment(MCI)among older adults.Methods A literature review was conducted to construct a draft of the identification and intervention toolkit.Tools with an expert approval rate above 70%were included after expert consultation.The final version of the toolkit was developed by integrating these tools with officially recommended tools in China.Results The expert consultation yielded an authority coefficient of 0.84.The finalized toolkit included the assessment tools of Mini-Mental State Examination,Montreal Cognitive Assessment,General Practitioner Assessment of Cognition,Cognitive Abilities Screening Instrument and Clock Drawing Test,and 18 intervention measures in-cluding pharmacological treatment,cognitive training and psychological interventions,etc.Conclusion The MCI Identification-Intervention Toolkit may serve as a reference for guiding the identification and inter-vention of MCI among older adults for community health institutions.

For patients with advanced non-small cell lung cancer (NSCLC) harboring sensitive epidermal growth factor receptor (EGFR) mutations, guidelines prioritize the use of third-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs), which offer higher objective response rate (ORR), longer progression-free survival (PFS), and better quality of life. However, due to the low proportion of elderly patients enrolled in clinical trials, the existing evidence is insufficient to fully guide clinical practice. This review examines the efficacy and safety differences of third-generation EGFR-TKIs as monotherapy or in combination in the elderly NSCLC by integrating subgroup analyses or pre-specified research objectives from prospective and retrospective studies. The results show that third-generation EGFR-TKIs have comparable efficacy in elderly patients to younger populations and are well-tolerated. Although combination therapies may extend survival time, the associated increased toxicity necessitates careful risk-benefit assessment.

Objective To investigate the diagnostic value of serum human β-defensin 2(HBD2)and soluble growth stimulating gene 2(sST2)levels in pediatric refractory Mycoplasma pneumonia.Methods A total of 145 children diagnosed with Mycoplasma pneumonia were recruited,and divided into refractory pneumonia group(n=53)and common pneumonia group(n=92)based on whether they had refractory or common pneumonia.General data were compared between the two groups.Ser-um HBD2 and sST2 levels were measured using enzyme-linked immunosorbent assay(ELISA).Multi-variate logistic regression analysis was used to identify influencing factors for the occurrence of refracto-ry Mycoplasma pneumonia.Receiver operating characteristic(ROC)curve analysis was performed to evaluate the diagnostic value of serum HBD2 and sST2 levels in refractory Mycoplasma pneumonia.Results The proportion of lung consolidation and pleural effusion in refractory pneumonia group was significantly higher,and the fever time was significantly longer than that in common pneumonia group(P＜0.05).Serum HBD2 and sST2 levels in the refractory pneumonia group were signifi-cantly higher than those in the common pneumonia group(P＜0.05).Multivariate Logistic regres-sion analysis indicated that lung consolidation,pleural effusion,high serum HBD2 level and high serum sST2 level were risk factors for pediatric refractory Mycoplasma pneumonia(P＜0.05).The area under the curve and Youden's index for diagnosing pediatric refractory Mycoplasma pneumonia were 0.817 and 0.557 for serum HBD2 level,and 0.841 and 0.607 for serum sST2 level,respec-tively.Combined diagnosis using both markers resulted in an area under the curve of 0.916 and a Youden's index of 0.721.Conclusion The combined detection of serum HBD2 and sST2 levels holds significant diagnostic value for pediatric refractory Mycoplasma pneumonia.

Objective:To analyze the latent prevalence of hepatitis B and type 2 diabetes and their correlation through an observational study.Methods:This study used a case-control design. The cases with diabetes were recruited through the diabetes management system and village doctors, while the controls without diabetes were screened from volunteers recruited by village health clinics. Capillary blood samples were collected from the study participants for the measurement of real-time blood glucose level, and venous blood samples were taken from them for the detections of HBV serological markers. Firth logistic regression model was used to fit the relationship between HBsAg positive status and diabetes status.Results:The study included 1 218 diabetes patients, 62 patients with impaired fasting glucose and 491 cases without diabetes. In the cases without diagnosis of diabetes, 11.15% had impaired fasting blood glucose and 4.43% had diabetes. Among those who reported no or unknown diagnosis of hepatitis B, 1.73% were positive for HBsAg, while 18.80% were positive for both HBV core antibody and surface antibody, indicating latent infection of hepatitis B virus. In the non-diabetes group, 0.81% reported hepatitis B history, and in the diabetes group, 2.76% reported hepatitis B history. After adjustment, the HBsAg positive rate was higher in the diabetes group ( OR=2.90, 95% CI: 1.21-6.91). Conclusions:Both diabetes and hepatitis B exhibited a high degree of latent prevalence. The HBsAg positive rate was significantly higher in those with diabetes than in those without diabetes, indicating a potential correlation. These findings highlighted the importance of strengthened screening and management of comorbidities.
