Immune suppression in the tumor microenvironment (TME) is closely related to abnormal glycolysis. Tumor cells gain metabolic advantages and suppress immune responses through the "Warburg effect". Traditional Chinese medicine (TCM) has been shown to regulate key glycolysis enzymes (such as HK2 and PKM2), metabolic signaling pathways (such as PI3K/AKT/mTOR, HIF-1α) and non-coding RNAs at multiple targets, thus synergistically inhibiting lactate accumulation, improving vascular abnormalities, and relieving metabolic inhibition of immune cells. Studies have shown that TCM monomers and formulas can promote immune cell infiltration and functions, improve metabolic microenvironment, and with the assistance by the nano-delivery system, enhance the precision of treatment. However, the dynamic mechanism of the interaction between TCM-regulated glycolysis and TME has not been fully elucidated, for which single-cell sequencing and other technologies provide important technical support to facilitate in-depth analysis and clinical translational research. Future studies should be focused on the synergistic strategy of "metabolic reprogramming-immune activation" to provide new insights into the mechanisms of tumor immunotherapy.

Objective To explore the effect of Endoanal advancement flap(ERAF)and transanal opening of interphincteric space(TROPIS)in the treatment of complex anal fistula and their impact on anorectal pressure,so as to provide a reference for clinical selection of surgical methods.Methods Eighty-four patients with complex anal fistula admitted from October 2018 to October 2022 were divided into group E received ERAF treatment(n=48)and group T received TROPIS treatment(n=36).The clinical efficacy,operation,wound surface and anorectal pressure of the two groups were compared.Results The effective rate of treatment in Group T was 97.22％,which was higher than that in Group E(87.50％),with no statistically significant difference(P＞0.05).The surgical time[(31.53 ±7.29)minutes],intraoperative bleeding volume[(29.56±7.37)ml],and wound area[(10.03± 0.96)cm2,(8.76±0.87)cm2,(6.20±0.77)cm2]on the day of surgery,7 and 14 days after surgery in Group T were all smaller than those in Group E[(35.36±8.54)min,(36.86±8.04)ml,(12.09± 1.23)cm2,(10.52±1.09)cm2 and(7.36±0.85)cm2](P＜0.05).After surgery,the VAS score and Wexner incontinence score of Group T were(1.38±0.27)and(0.21±0.08),respectively.Group E was(1.56±0.29)and(0.33±0.09),respectively.In group T,the anorectal systolic pressure at 20 mm and 30 mm and the anorectal resting pressure at 20 mm and 30 mm were(138.18±29.58)mmHg,(136.22±35.41)mmHg,(35.47±6.58)mmHg,and(32.97±8.01)mmHg,respectively.In Group E,the data was(152.78±31.53)mmHg,(156.29±32.74)mmHg,(38.29±7.62)mmHg and(36.41±7.63)mmHg,respectively.Both groups showed a decrease in score and anorectal pressure,and group T was lower than group E(P＜0.05).The incidence of adverse reactions in Group E was 20.83％,which was higher than that in Group T(11.11％),but the difference was not statistically significant(P＞0.05).Conclusion TROPIS has a better effect in the treatment of complex anal fistula,which can shorten the operation time,reduce intraoperative bleeding,reduce postoperative pain,and protect anal function.

OBJECTIVE To explore the action mechanism of kushenol F （KSCF） in treating ulcerative colitis （UC） in mice. METHODS The potential targets of KSCF intervening in UC were predicted with network pharmacology and molecular docking. C57BL/6J mice were randomly divided by body weight into model group， positive control group （sulfasalazine， 703 mg/kg）， KSCF group （100 mg/kg）， and normal group， with 6 mice per group. The UC model of mice was induced by dextran sulfate sodium solution. During the modeling period， the mice were given relevant medicine intragastrically， once a day， for 7 consecutive days. After the last administration， the disease activity index （DAI） of the mice was scored； the length of the mice’s colon was measured； pathological changes in the colon tissue of mice were observed； the levels of lipopolysaccharide （LPS） in serum， myeloperoxidase （MPO）， nitric oxide （NO） and superoxide dismutase （SOD） in the colon were detected in mice； the expression levels of occludin and ZO-1 in colon tissue of mice were detected； the proportions of CD3+T， CD4+T， and CD8+T lymphocytes in the spleen and the ratio of CD4+/CD8+ were detected； changes in colonic microbiota were analyzed by 16S rDNA sequencing. RESULTS Results of network pharmacology indicated that KSCF may treat UC by regulating signaling pathways such as phosphatidylinositol-3 kinase/protein kinase B （PI3K/AKT） and nuclear factor kappa B （NF- κB）. Molecular docking results showed that KSCF bound most stably with NF-κB p65 protein. Animal experiment results demonstrated that， compared with the model group， the pathological characteristics of colon tissue in mice were improved in KSCF group. DAI scores， serum levels of LPS， the levels of MPO，NF-κB p65 phosphorylation and NLRP3 protein expression in the colon， and the proportion of CD8+T lymphocytes in the spleen were reduced significantly （P＜0.05）. Body weight， SOD levels， expression levels of occludin and ZO-1 in the colon， proportions of CD3+T and CD4+T lymphocytes， and the CD4+/CD8+ ratio in the spleen were significantly increased （P＜0.05）； the abundance of Firmicutes， Actinobacteria， Akkermansia， and Lactobacillus genera were increased， while Proteobacteria decreased； the microbial community structure tended towards that of the normal group. CONCLUSIONS KSCF alleviates UC by restoring intestinal microbial imbalance， enhancing immune response， and inhibiting colonic inflammatory responses， thereby improving intestinal barrier integrity.

Background and Purpose:The early prediction of local tumor progression-free survival(LTPFS)after radiofrequency ablation(RFA)for colorectal cancer(CRC)lung metastases has significant clinical importance.The application of radiomics in the prediction of tumor prognosis has been explored.This study aimed to construct a radiomics-based nomogram for predicting LTPFS after RFA in CRC patients with lung metastases.Methods:This study retrospectively analyzed 172 CRC patients with 401 lung metastases admitted to Department of Interventional Radiology,Fudan University Shanghai Cancer Center from August 2016 to January 2019.This study was reviewed by the medical ethics committee of Fudan University Shanghai Cancer Center(ethics number:2402291-24).After augmentation of pre-ablation and immediate post-ablation computed tomography(CT)images,the target metastases and ablation regions were segmented manually to extract the radiomic features.Maximum relevance and minimum redundancy algorithm(MRMRA)and least absolute shrinkage and selection operator(LASSO)regression models were applied for feature selection.The clinical model,the radiomics model,and the fusion model were constructed based on the selected radiomic features and clinical variables screened by the multivariate analysis.The Harrell concordance index(C-index)and area under receiver operating characteristic(ROC)curves(AUC)were calculated to evaluate the prediction performance.Finally,the corresponding nomogram of the best model was drawn.Results:Among all the lung metastases,102(25.4%)had final recurrence,and 299(74.6%)had complete response(CR).The median follow-up time was 21 months(95%CI:19.466-22.534),and the LTPFS rates at 1,2,and 3 years after RFA were 76.5%(95%CI:72.0-80.4),72.1%(95%CI:66.6-76.9)and 69.9%(95%CI:64.0-75.1).In both the training and test dataset,the fusion model based on the final 12 radiomic features through the LASSO regression and 4 clinical variables screened by multivariate analysis achieved the highest AUC values for LTPFS,with C-index values of 0.890(95%CI:0.854-0.927)and 0.843(95%CI:0.768-0.916),respectively.Conclusion:The fusion model based on radiomic features and clinical variables is feasible for predicting LTPFS after RFA of CRC patients with lung metastases,whose performance is superior to the single radiomic and clinical model.At the same time,the nomogram of the fusion model can intuitively predict the prognosis of CRC patients with lung metastases after RFA,thus assisting clinicians in developing individualized follow-up review plans for patients and adjusting treatment strategies flexibly.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Subretinal fibrosis(SRF),the end pathological stage of neovascular age-related macular degeneration(nAMD),can cause severe and irreversible vision loss in patients.In recent years,the high clinical incidence of SRF and the severe visual impairment it causes have led to a rapid development of SRF-related research.In order to systematically understand the clinical progress of SRF,recent studies on SRF secondary to nAMD were reviewed in this article.

Objective:To investigate and analyze the current situation and influencing factors of the establishment demand for electronic health records (EHR) of residents in Sichuan and Hainan Province under the “Internet+healthcare” ecology.Methods:It was a cross-sectional study. A total of 1 200 residents in Sichuan and Hainan Province were selected with convenient sampling method from June to December 2022. A self-designed questionnaire was conducted through the Questionnaire Star online survey, and the survey mainly included general demographic data and basic establishment demands of electronic health records. A total of 1 200 questionnaires were distributed and 1 200 questionnaires returned with 1 170 valid questionnaires (97.5%), including 409 from Sichuan and 761 from Hainan. Chi-square test was used to compare the differences between the two provinces in the demographic characteristics, basic needs, and binary variables of willingness to application file establishment and physical examination file establishment. Kruskal-Wallis test was used to compare the differences in multiple categorical variables between the two provinces. Binary logistic regression was used to analyze the influencing factors of the establishment needs of the electronic health records.Results:The proportions of residents with bachelor degree or above and those with a family population of less than 3 people in Sichuan were both significantly higher than those in Hainan (55.3% vs 47.4%, 38.4% vs 29.2%); but the proportions of mean monthly income ≤10 000 yuan, annual physical examination, self-health management habits, and having children were all significantly lower than those in Hainan (82.2% vs 87.9%, 67.2% vs 74.4%, 78.5% vs 83.7%, 67.2% vs 73.3%) (all P<0.05). The people who were living in the city, having a mean monthly income >10 000 yuan, receiving annual physical examination, not lived alone, having self-health management habits, knowing the electronic health record, willing to manage the electronic health record by themselves, expecting to manage the health record online, needing special assistance to manage the health record, and willing to pay for additional services were more likely to use the application to establish health records (68.7% vs 56.7%, 82.4% vs 63.0%, 72.2% vs 55.3%, 68.8% vs 62.7%, 69.0% vs 60.4%, 73.2% vs 60.4%, 71.9% vs 36.7%, 71.5% vs 45.7%, 76.6% vs 43.3%, 80.1% vs 44.0%) (all P<0.05). Residents who lived in cities, had annual physical examination, had children, and were willing to manage health records by themselves were more likely to establish physical examination files (46.0% vs 32.5%, 47.9% vs 36.2%, 47.1% vs 33.2%, 45.9% vs 34.4%) (all P<0.05). Willing to manage electronic health records by themselves ( OR=3.803, 95% CI: 2.013-6.875), managing electronic health records online ( OR=1.942, 95% CI: 1.110-3.400), managing electronic health records with dedicated person ( OR=3.277, 95% CI: 2.028-5.294), willing to pay for electronic health records ( OR=3.557, 95% CI: 2.182-5.800), having electronic physical examination records ( OR=1.850, 95% CI: 1.191-2.872) were positively correlated with the willingness to use the application to establish health files, and the age ( OR=0.681, 95% CI: 0.469-0.989) was negatively correlated with the willingness to use the application to establish health files (all P<0.05). Having chronic diseases ( OR=1.389, 95% CI: 1.032-1.868) and willing to manage electronic health records by themselves ( OR=1.553, 95% CI: 1.004-2.401) were positively correlated with willingness to set up health files. Receiving annual physical examination ( OR=0.669, 95% CI: 0.497-0.901), willing to pay for electronic health records ( OR=0.576, 95% CI: 0.423-0.783), willing to use the application to establish health files ( OR=0.715, 95% CI: 0.582-0.979) were negatively correlated with willingness to establish files for physical examination (all P<0.05). Conclusion:Residents in Sichuan and Hainan Province have a high demand for electronic health records, which is affected by many factors. Age and chronic diseases are the significant factors influencing residents′ choices of using apps and physical examinations to establish their health records.

Human herpesvirus-6 (HHV-6) is a ubiquitous virus. The incidence of HHV-6 after liver transplantation is estimated to be 22% ? 54%; it may present with fever, hepatitis, pneumonia, encephalitis, and myelosuppression and has a poor prognosis. HHV-6(+) recipients had a mortality rate of 29%, significantly higher than that of HHV-6(?) recipients (6%). Since most infections are asymptomatic, HHV-6 monitoring is not routinely performed in clinical practice, which means clinicians often ignore the diagnosis of HHV-6 and eventually delay diagnosis and treatment. In this paper, a case of human herpesvirus 6B encephalitis after liver transplantation was retrospectively analyzed, and the literature related to this disease was reviewed to improve the understanding of this disease.

Ischemic stroke(IS)is a multifactorial and heterogeneous disease.Despite years of studies,effective strategies for the diagnosis,management and treatment of stroke are still lacking in clinical practice.Metabolomics is a growing field in systems biology.It is starting to show promise in the identification of biomarkers and in the use of pharmacometabolomics to help patients with certain disorders choose their course of treatment.The development of metabolomics has enabled further and more biological appli-cations.Particularly,metabolomics is increasingly being used to diagnose diseases,discover new drug targets,elucidate mechanisms,and monitor therapeutic outcomes and its potential effect on precision medicine.In this review,we reviewed some recent advances in the study of metabolomics as well as how metabolomics might be used to identify novel biomarkers and understand the mechanisms of IS.Then,the use of metabolomics approaches to investigate the molecular processes and active ingredients of Chinese herbal formulations with anti-IS capabilities is summarized.We finally summarized recent developments in single cell metabolomics for exploring the metabolic profiles of single cells.Although the field is relatively young,the development of single cell metabolomics promises to provide a powerful tool for unraveling the pathogenesis of IS.

Objective:To assess the early clinical outcomes of Oxford cementless unicompartmental knee arthroplasty (UKA) in the management of anteromedial osteoarthritis of the anterior medial knee (AMOA).Methods:A retrospective review was conducted on a cohort of 90 patients who underwent primary UKA for AMOA at the Fuzhou Second Hospital between January 2020 and June 2021. The patients were divided into two groups based on the type of prosthesis used: the cementless UKA group and the cemented UKA group. The cementless UKA group included 45 patients (22 males and 23 females), with a mean age of 65.6±7.0 years (ranging from 52 to 81 years). The cemented UKA group consisted of 45 patients, including 21 males and 24 females, with a mean age of 67.9±6.1 years (ranging from 55 to 79 years). The study compared various parameters between the two groups, including the duration of surgery, amount of blood loss, length of hospitalization, pain visual analogue scale (VAS) scores, Hospital for Special Surgery (HSS) scores, and forgotten joint score (FJS). Additionally, radiolucency around the prosthesis, medial proximal tibial angle (MPTA), and mechanical axis deviation (MAD) were observed and measured before and after surgery to assess prosthesis stability, improvement of knee deformity, and knee joint mobility, respectively.Results:Both groups were followed up for a minimum of 18 months. No statistically significant differences were found in demographic data such as gender, age, and body mass index between the two groups. The cementless UKA group demonstrated superior results in terms of shorter duration of surgery (97.8±21.1 min) and less blood loss (70.8±37.6 ml) compared to the cemented UKA group ( P<0.05). However, no significant difference in length of stay was observed between the groups. Postoperative VAS scores, HSS scores, MPTA, and MAD were significantly improved compared to preoperative values in both groups ( P<0.05). The median VAS scores for the cementless UKA group at 6, 12, and 18 months postoperatively were 4.0(3.0, 5.0), 2.0(2.0, 3.0), and 2.0(1.0, 3.0) respectively. The corresponding median HSS scores for the cemented UKA group were 78(75, 82), 85 (80, 89), and 86(82, 90) preoperatively and at 6, 12, and 18 months postoperatively, respectively. The median FJS scores for the cementless UKA group were 73.0(70.5, 76.0), 76.0(74.0, 78.0), and 66.0(63.0, 68.0) preoperatively and at 6, 12, and 18 months postoperatively, respectively. There was no statistically significant relationship between preoperative VAS scores and preoperative FJS scores ( P>0.05). However, there was a significant difference in VAS scores between the two groups at 6 months postoperatively ( P<0.05). The cementless UKA group consistently exhibited better VAS scores and HSS scores compared to the cemented UKA group at 6, 12, and 18 months postoperatively ( P<0.05). The median MPTA values for the cementless UKA group were 85.41°(84.22°, 86.54°), 85.80°(84.74°, 87.41°), 86.51°(85.47°, 88.14°), and 86.80°(86.09°, 88.27°) preoperatively and at 6, 12, and 18 months postoperatively, respectively. The median MAD values for the cementless UKA group were 2.29(1.79, 2.65) cm, 1.11(0.69, 1.75) cm, 1.02(0.65, 1.66) cm, and 0.91(0.61, 1.63) cm preoperatively and at 6, 12, and 18 months postoperatively, respectively. There were no significant differences in MPTA and MAD between the two groups at all time points, except for the preoperative MPTA and postoperative MAD at 6 and 12 months. The incidence of physiological radiolucency around the prosthesis was significantly lower in the cementless UKA group 3 than in the cemented UKA group 28 ( P<0.05). However, no complete radiolucency was observed in either group. Conclusion:Oxford cementless UKA is a highly effective treatment for relieving joint pain and correcting knee deformity in patients with knee AMOA. It offers the advantages of shorter surgical duration, reduced blood loss, and improved subjective outcomes for patients after the operation.
