AIM To explore the clinical effects of Heiguteng Zhuifeng Huoluo Capsules combined with warm acupuncture at musculotendinous pathological nodes on patients with knee osteoarthritis due to Cold-Dampness Obstruction and Fixed Impediment.METHODS One hundred and sixty patients were randomly assigned into control group(80 cases)for 4-week intervention of both warm acupuncture at musculotendinous pathological nodes and Celecoxib Capsules,and observation group(80 cases)for 4-week intervention of Heiguteng Zhuifeng Huoluo Capsules,warm acupuncture at musculotendinous pathological nodes and Celecoxib Capsules.The changes in clinical effects,TCM syndrome scores,WOMAC scores,Lequesne indices,pain mediators(PGE2,β-EP),growth factors(TGF-β1,IGF-1),bone metabolism indices(OPG,RANKL),TLR4/NF-κB signaling pathway and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome scores,WOMAC scores,Lequesne indices,PGE2,RANKLE,TLR4,NF-κB(P＜0.05),and increased β-EP,growth factors,OPG(P＜0.05),especially for the observation group(P＜0.05).No serious adverse events or reactions were observable in the two groups.CONCLUSION For the patients with knee osteoarthritis due to Cold-Dampness Obstruction and Fixed Impediment,Heiguteng Zhuifeng Huoluo Capsules combined with warm acupuncture at musculotendinous pathological nodes can safely and effectively alleviate clinical symptoms,improve knee joint pain,and enhance joint functions,whose action mechanisms may contribute to the inhibition of TLR4/NF-κB signaling pathway expression and regulations of serum TGF-β1,IGF-1,OPG,RANKL levels.

Solid-phase extraction(SPE)combined with surface-enhanced Raman spectroscopy(SERS)has emerged as a promising analytical technique for detection and analysis of trace components in complex sample matrices.SPE enriches analytes through selective adsorption and solvent elution,effectively increasing the concentration and signal intensity.SERS enables ultra-sensitive and highly selective molecular analysis through the use of SERS-active substrates engineered to amplify Raman signals.The integration of these two techniques overcomes the limitations of conventional Raman spectroscopy in low-concentration detection field,while significantly improving sample preparation efficiency and analytical accuracy.This review provided a comprehensive overview of the characteristics of three SPE-SERS coupling modes,including two-step,one-step,and online integration.Special emphasis was placed on recent advancements in one-step SPE-SERS approaches based on novel functional adsorbent materials such as graphene,metal-organic frameworks,covalent organic frameworks,and molecularly imprinted polymers.Furthermore,future directions and development prospects of SPE-SERS technology were discussed.

Objective The aim of this study was to analyze the incidence trend and age-specific characteristics of esophage-al cancer in cancer registration areas of Gansu Province from 2010 to 2021,and predict the incidence of esophageal cancer from 2022 to 2030.Methods Based on the incidence data of esophageal cancer in 15 cancer registries in Gansu Province from 2010 to 2021,the incidence was calculated by age,sex,urban and rural areas.The age-standardized incidence by Chinese standard population(ASIRC)was standardized using the 2000 Chinese standard population.Joinpoint regression model was used to analyze the change trend of esophageal cancer incidence,and the average annual percentage change(AAPC)was calculated to quantify the overall rate of change.A birth cohort model was constructed to analyze incidence trend of different birth groups from 1930 to 2021,and the Bayesian age-period-cohort(BAPC)model was used to predict incidence.Results From 2010 to 2021,the ASIRC of esophageal cancer in Gansu Province showed a significant downward trend(AAPC=-14.47％,95％CI:-18.72％--9.99％,P＜0.001).The ASIRC in men decreased at an annual rate of 13.02％(AAPC=-13.02％,95％CI:-17.28％--8.54％,P＜0.001),the incidence of esophage-al cancer in women at a rate of 15.80％per year(AAPC=-15.80％,95％CI:-20.69％--10.61％,P＜0.001).The ASIRC of e-sophageal cancer in urban areas decreased at an annual rate of 15.32％(AAPC=-15.32％,95％CI:-21.04％--9.18％,P＜0.001);ASIRC of esophageal cancer in rural areas decreased at a rate of 5.33％per year(AAPC=-5.33％,95％CI:-8.94％--1.58％,P＜0.001).From 2010 to 2021,the incidence of esophageal cancer in all age groups showed a significant downward trend(AAPC:-19.59％to-9.18％).The birth cohort analysis revealed that the incidence of esophageal cancer in people over 40 years old in the province,men,women,urban and rural areas showed a downward trend with increase of birth years.BAPC model predicted that that the ASIRC of esophageal cancer for the total province population,men and women would decrease from 6.47/100,000,10.02/100,000,and 2.95/100,000 in 2021 to 1.31/100,000,1.72/100,000,and 0.91/100,000 in 2030,respectively.Conclu-sions The incidence of esophageal cancer in Gansu Province showed a downward trend from 2010 to 2021,but men and rural areas were still the focus of high incidence.The prediction indicates that the incidence of esophageal cancer in Gansu Province will further decline by 2030,suggesting that the prevention and control measures have achieved results;however,it is still necessary to strengthen the intervention and long-term monitoring of high-risk groups.

Sinopodophyllum hexandruma is a traditional Chinese medicine in China,which is mostly distributed in Gansu,Shaanxi,Sichuan,Qinghai,Yunnan and Xizang,etc.In recent years,with the gradual deepening of the research on the chemical composition and pharmacology-toxicology of Sinopodophyllum hexandruma,its antitumour and antiviral pharmacodynamic evaluation has increasingly become a research hotspot in the industry.Based on the chemical structure,pharmacological properties and the theoretical basis of quality markers(Q-markers),this paper presents an in-depth literature review and analysis of the chemical composition,pharmacological activities and Q-markers of Sinopodophyllum hexandruma,and systematically explores and predicts the Q-markers of Sinopodophyllum hexandruma.It is proposed that Podophyllotoxin,picropodophyllotoxin,podophyllotoxinone,quercetin,kaempferol,quercetin-3-O-β-glucoside can be used as the Q-marker of Sinopodophyllum hexandruma.In the later stage,these index components can be selected to control the whole quality of Sinopodophyllum hexandrum,and provide some data support and theoretical reference for the quality evaluation of Sinopodophyllum hexandrum.

Objective:To explore the short-term clinical effects of deep cervical lymph node-venous anastomosis in the treatment of Alzheimer’s disease (AD).Methods:A prospective exploratory study was conducted on the treatment of AD patients using the cervical deep lymph node-venous anastomosis technique in Scar and Wound Treatment Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from September to October 2024. The patients underwent high-frequency ultrasound to locate deep cervical lymph nodes and the external jugular vein. Under general anesthesia, bilateral deep cervical lymph node-venous anastomoses were performed. Indocyanine green (ICG) lymphography was conducted via subcutaneous injection behind the ear to visualize lymph nodes in levels Ⅱ and Ⅲ. After making a skin incision along the posterior margin of the sternocleidomastoid muscle, the external jugular vein, internal jugular veins, and associated lymph nodes were exposed. Adjacent veins were selected for anastomosis of lymph node. Using microsurgical techniques, end-to-side or end-to-end anastomosis was completed for lymph nodes in levels Ⅱ and Ⅲ. Preoperative assessments included the mini-mental state examination (MMSE, a higher score indicates better cognitive function), Alzheimer’s disease assessment scale-cognitive subscale (ADAS-Cog, a higher score indicates greater impairment of cognitive function), Alzheimer’s disease cooperative study scale for activities of daily living (ADCS-ADL, a higher score indicates better ability to perform daily activity), and neuropsychiatric inventory (NPI, a higher score indicates more severe behavioral and emotional symptom). Postoperative follow-up included the same scales to observe changes in cognitive function, activities of daily living, and emotional communication.Results:Four patients (1 male, 3 females, aged 58-79 years) with AD were included. All were diagnosed based on cerebrospinal fluid biomarkers. All patients successfully underwent bilateral deep cervical lymph node-venous anastomoses. On average, 4.3 (2-7 per person) anastomoses were performed per patient. Surgical procedures lasted an average of 6.5 h (5.5-8.5 h) with minimal blood loss (less than 50 ml). Patients resumed normal activity within 6 hours postoperatively and were discharged after an average of 4.1 d (3.5-5.0 d). Postoperative complications included one case each of aspiration pneumonia, lower limb venous thrombosis, and transient delirium, all of whom resolved without long-term effects. Clinical symptoms, including memory decline, mood swings, and anxiety, showed varying degrees of improvement. Patients reported enhanced quality of life, emotional stability, and social engagement, confirming the procedure’s safety and potential cognitive benefits. At one month postoperatively, the MMSE scores of the four patients increased by an average of 0.8 points compared to preoperative levels. Additionally, the two patients who completed the ADAS-Cog assessments showed a decrease in their scores (reduced by 1.0 points and 11.3 points, respectively, compared to preoperative scores), indicating a certain degree of improvement in cognitive function during this period. The ADCS-ADL and NPI scores of four patients varied significantly, without showing any clear pattern.Conclusion:Lymphovenous anastomosis of the deep cervical lymph node-venous anastomosis may provide a new surgical intervention approach for AD, but further large-scale studies and long-term follow-up are needed to validate its safety and effectiveness.

OBJECTIVE To evaluate the quality of diagnosis and treatment guidelines and expert consensuses on childhood immune thrombocytopenic purpura(ITP)published domestically and internationally,in order to provide reference for clinical practice and future guideline/expert consensus development and improvement.METHODS A systematic search was conducted across multiple databases,including PubMed,Cochrane Library,Embase,CNKI,Wanfang data,VIP,CBM;additionally,supplementary searches were carried out on websites such as Medlive,the Chinese Medical Association's official website,and National Institute for Health and Clinical Excellence in the UK.The retrieval time ranged from the inception to September 2,2024.Researchers who had undergone systematic training independently evaluated the methodology and report quality included in the guideline/consensus using the Appraisal of Guidelines Research and Evaluation Ⅱ(AGREE Ⅱ)and the Reporting Items for Practice Guidelines in Healthcare(RIGHT).RESULTS A total of 11 guidelines/consensuses were included.The average scores for the six domains of AGREE Ⅱ tool respectively were"range and purpose"[(66.67±17.98)%],"participants"[58.33%(13.89%,73.61%)],"rigor"[(41.81±23.85)%],"clarity"[(69.57±19.35)%],"applicability"[(35.98±17.83)%],and"independence"[27.08%(0,75.00%)];out of 11 articles,9 had a recommendation level of B,2 had a recommendation level of C,and there were no A-level articles.The average reporting rates of the 7 areas in the RIGHT tool were"basic information"[(72.35±12.95)%],"background"[(54.55±15.40)%],"evidence"[(36.36±24.81)%],"recommended opinions"[(53.25±19.20)%],"review and quality assurance"[0(0,25.00%)],"funding and conflict of interest statement and management"[12.50%(0,25.00%)],and other aspects[8.33%(0,50.00%)].In addition,there was no statistically significant difference in the AGREE Ⅱ and RIGHT scores between the guidelines and consensuses(P＞0.05).CONCLUSIONS The overall quality of the guidelines and consensuses included in this study is not high,with a recommended level of B or C.It is recommended that clinical decision-making prioritize referring to the relatively high-quality guideline/consensus among them.The quality of evidence in the existing traditional Chinese medicine guidelines for children with ITP needs to be improved,and there is no integrated guideline/consensus for traditional Chinese and Western medicine.It is recommended to revise or write relevant guideline/consensus according to the requirements of AGREE Ⅱ and RIGHT in various fields to guide clinical practice.
