OBJECTIVES: To investigate the mechanism through which salidroside inhibits proliferation of gastric cancer (GC) cells focusing on glucose metabolic reprogramming pathways. METHODS: High-throughput sequencing combined with bioinformatics analysis was employed to identify the potential targets of salidroside in human GC MGC-803 cells. Liposome-mediated transfection experiments were carried out to validate the functional and mechanistic roles of these targets. CCK-8 and colony formation assays were used to assess the effects of salidroside on GC cell viability and clonogenic ability. qRT-PCR, Western blotting, and biochemical assay kits were used to analyze the regulatory effects of salidroside on the miR-1343-3p-OGDHL/PDHB enzyme complex-pyruvate metabolic pathway in GC cells. RESULTS: Bioinformatics analysis suggested that the tumor-suppressive factor miR-1343-3p negatively regulated the key glycolytic enzyme gene oxoglutarate dehydrogenase-like (OGDHL) in GC cells, and OGDHL and pyruvate dehydrogenase E1 subunit beta (PDHB) were both significantly upregulated in GC tissues, which was close by correlated with reduced survival rates of GC patients. In MGC-803 cells, salidroside treatment significantly enhanced the expression level of miR-1343-3p and downregulated OGDHL expression, resulting in disruption of the stability of PDHB, reduced pyruvate oxidative decarboxylation, and consequently decreased production of acetyl-CoA and ATP. CONCLUSIONS Salidroside inhibits GC cell proliferation possibly by regulating the miR-1343-3p-OGDHL/PDHB enzyme complex-pyruvate metabolic pathway, which provides new insights into its anti-tumor mechanisms and suggests new strategies for targeted therapy for GC.

Endometrial cancer is one of the common malignant tumors of the female reproductive system.Its incidence rate in China is second only to cervical cancer,posing a serious threat to women's life and health,and the onset shows a trend of affecting younger individuals.Currently,the primary treatment for endometrial cancer is surgical intervention,and some postoperative patients and those with postoperative recurrence require adjuvant radiotherapy.Pelvic external beam radiotherapy(EBRT)and vaginal brachytherapy(VBT)are two modalities of postoperative radiotherapy.The appropriate postoperative radiotherapy approach should be selected based on individual conditions and guideline recommendations.Most patients can achieve satisfactory treatment outcomes through surgery and postoperative adjuvant radiotherapy.However,the specific indications for postoperative radiotherapy in endometrial cancer patients and the radiotherapy principles for those with postoperative recurrence are relatively complex,and recommendations for radiotherapy modalities in postoperative patients vary slightly across different guidelines.This article reviews the treatment principles for endometrial cancer patients in recent years,as well as the indications for postoperative and post operative recurrent radiotherapy and the radiotherapy techniques,aiming to provide a reference for radiotherapy in the endometrial cancer patients.

Objective To compare the surgical outcomes of the sequence of screw and rod placement for Lenke type 5C adolescent idiopathic scoliosis(AIS).Methods Lenke type 5C AIS patients who underwent posterior orthopedic fusion and fixation in our hospital from Jan.2013 to Dec.2020 were recruited.Based on surgical sequences,22 cases were assigned to bilateral group(after bilateral screw placement,orthopedics was performed on the convex side and then on the concave side),and 20 cases were assigned to convex group(screws placed on the convex side and performed orthopedics,followed by the concave side).The operation-related indicators(including operation time),imaging parameters,quality of life scores were compared between the 2 groups before and 2 years after surgery.Complications of the 2 groups were analyzed.Results The operation time in the bilateral group was significantly longer than that in the convex group([232.8±13.1]min vs[198.4±16.5]min,P＜0.01).At the last follow-up 2 years after operation,the Cobb angle and its correction rate in the convex group were better than those in the bilateral group([8.0±2.3]° vs[9.9±3.2]°,P=0.03;[81.9±5.4]%vs[77.8±5.8]%,P=0.02).The rate of pedicle screw breach rate was 5.4%(17/312)in the bilateral group and 1.4%(4/280)in the convex group,with significant difference(P＜0.01).At the last follow-up 2 years after operation,the treatment satisfaction of quality of life assessment of the bilateral group was 4.61±1.38,and that of the convex group was 4.50±1.44,but there was no significant difference between the 2 groups(P＞0.05).There were no abnormal electrophysiological monitoring or operation-related complications in the 2 groups.Conclusion For Lenke type 5C AIS,the convex side of pedicle screw placement and orthopedics followed by concave side of pedicle screw placement and orthopedics can achieve better surgical effect.

In the past, aortic dissection, aortic aneurysm, and other aortic diseases, primarily rely on surgical intervention. In recent years, due to breakthroughs in materials science, endovascular therapy has become the first choice for the surgical treatment of most aortic diseases. However, traditional endovascular repair cannot fully meet the clinical needs for certain complex lesions involving the aortic arch and the originations of visceral arteries. The emergence of physician-modified stent technology has brought new hope for the treatment of complex aortic diseases. This article provides a detailed introduction to the concept, development, technical characteristics, and applications of physician-modified stents in the treatment of aortic diseases, analyzing their advantages and limitations. Physician-modified stents serve as a powerful complement to traditional endovascular interventions and commercial branched stents, yet further research and refinement are still required.

Objective:To compare the efficacy and safety of Rotarex mechanical thrombectomy (Rotarex) combined with drug-coated balloon (DCB) versus percutaneous transluminal angioplasty (PTA) combined with DCB in the treatment of femoropopliteal artery in-stent restenosis (ISR).Methods:A multicenter, prospective, randomized controlled trial was conducted. 46 patients with femoropopliteal artery ISR admitted to five hospitals (Beijing Friendship Hospital, Capital Medical University; Beijing Chaoyang Hospital, Capital Medical University; Beijing Jishuitan Hospital, Capital Medical University; Xuanwu Hospital, Capital Medical University; Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University) from July 2020 to June 2024 were enrolled. Patients were randomly divided into the Rotarex+ DCB group ( n=24) and the PTA+ DCB group ( n=22) using a random number table. The clinical data of the two groups were collected, including clinical characteristics, Fontaine classification, stent placement location, stent duration, and lesion length. The primary endpoint was the target blood vessel patency rate at 6 and 12 months postoperatively; the secondary endpoints included improvement in clinical symptoms (Fontaine classification), rate of reintervention, and safety indicators. Measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for comparison between groups; count data were expressed as the number of cases and percentages, and intergroup comparisons were performed using the Chi-test or Fisher exact probability method. Results:At 12 months postoperatively, the target blood vessel patency rate in the Rotarex+ DCB group was significantly higher than that in the PTA+ DCB group (81.8% vs 45.5%, P=0.012), and the proportion of patients in Fontaine classification stage I was also higher (86.4% vs 45.5%, P=0.004). The results at the 6-month follow-up were consistent (target blood vessel patency rate: 87.0% vs 59.1%, P=0.035). In terms of safety, no severe complications such as arterial rupture, amputation, or procedure-related death occurred during the perioperative period in either group. During the postoperative follow-up, no amputation or procedure-related deaths occurred in either group. Conclusion:For the treatment of femoropopliteal artery ISR, Rotarex mechanical thrombectomy combined with DCB is significantly superior to PTA+ DCB in terms of 12-month target blood vessel patency rate and improvement of clinical symptoms, with comparable safety.

In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

This paper interprets the disease name related to bi （痹） disease in traditional Chinese medicine （TCM） from the perspective of micropathological phenotypes in knee osteoarthritis （KOA）. By systematically reviewing classical TCM literature on the pathogenesis and clinical features of different subtypes such as damp-retention bi， bone bi， and tendon bi， and integrating these with current research on pathological subtypes of KOA including the synovitis type， cartilage-meniscus type， and subchondral bone type， the study explores the correlation between traditional disease terms and modern micropathological phenotypes. The author proposes subtype classifications of damp-retention bi corresponding to synovial inflammation， bone bi related to abnormal subchondral bone remodeling， and tendon bi representing cartilage and meniscus degeneration. This approach provides a microscopic biological explanation for TCM syndrome differentiation and offers new perspectives for advancing integrative diagnostic and therapeutic strategies in both Chinese and western medicine.

Objective To investigate the molecular mechanism by which salidroside inhibits the proliferation of gastric cancer(GC)cells through upregulation of miR-1343-3p.Methods RNA databases were used to screen for mRNAs associated with tumor proliferation and with miR-1343-3p,and exhibiting significant changes in their expression levels after salidroside treatment of human GC cells.Gene matching and immunoprecipitation of RNA-binding proteins were conducted to analyze the association between miR-1343-3p and SOX18.Immunocytochemistry was performed to determine the localization of SOX18 protein.The effect of salidroside on the proliferation of human GC cells(MGC-803 and AGS)was determined by CCK-8 assay.Human GC cells were divided into a blank control group and low-and high-dose salidroside groups.The expression of miR-1343-3p and SOX18 mRNA was measured by real-time quantitative fluorescence PCR(qPCR).The protein expression of SOX18 was measured by Western blot.GC cells were co-transfected with miR-1343-3p mimic and miR-1343-3p inhibitor,respectively,via LipofectamineTM 2000 liposomes.The expression of miR-1343-3p and SOX18 mRNA was measured by qPCR,and the protein expression of SOX18 was measured by Western blot.Results Through bioinformatic analysis,SOX18 was identified as a downstream target of miR-1343-3p.Gene alignment confirmed the presence of specific binding sites between the two genes,and immunoprecipitation of RNA-binding proteins validated the targeting relationship between them(P<0.05).Immunocytochemistry demonstrated the nuclear localization of SOX18 protein.CCK-8 assay findings demonstrated that salidroside significantly inhibited the proliferation of GC cells in a time-and dose-dependent manner.Compared with the blank control group,salidroside-treated GC cells showed decreased expression of both SOX18 mRNA and protein(P<0.05)and an increased miR-1343-3p expression(P<0.05).Compared with the control group,GC cells in the miR-1343-3p mimic group exhibited increased expression of miR-1343-3p and decreased expression of SOX18 mRNA and protein.In contrast,GC cells in the miR-1343-3p inhibitor group showed decreased expression of miR-1343-3p and increased expression of SOX18 mRNA and protein(all P<0.05).Conclusion Salidroside may inhibit the proliferation of GC cells by regulating the miR-1343-3p/SOX18 signaling axis and these regulators may present new potential therapeutic targets or biomarkers for gastric cancer.

Objective To develop and validate a"quick self-assessment questionnaire for cochlear implant out-come(QSACI)".Methods A research team,composed of audiologists,otolaryngologists,data analysis experts,and cochlear implant(CI)recipients,was formed to establish objectives,research subject criteria,and framework of the QSACI.An item pool was creaed through literature review and brainstorming.Question items were evaluated and screened,and the framework and answer options of the questionnaire were established.The comprehensibility,etc.,was analyzed and refined through pilot test,interviews,and expert consultation,leading to the development of the final version.A total of 39 post-lingually deafened adults with known stable outcomes completed the question-naire.The split-half and test-retest reliabilty of the questionnaire was analyzed,and the validity was quantitatively analyzed by comparing scores with the categories of auditory performance(CAP)scores.Results The initial item pool of the questionnaire had 18 items,and the final questionnaire consisted of 12 questions in four dimensions:com-munication status,audiological status,medical factors,and other factors.The average score of 39 recipients was 88.81±6.17 and CAP was 6.19±0.94.The questionnaire showed good reliability and validity,with a Cronbach's alpha coefficient of 0.71 and a test-retest reliability of 0.824(P＜0.05).The criterion-related validity,assessed by the correlation between the self-assessment questionnaire scores and CAP scores,showed a significant moderate pos-itive correlation(r=0.512,P＜0.05).The correlation coefficient between self-assessment and professional assess-ment was 0.720(P＜0.05),indicating a significant correlation.The area under the receiver operating characterstic(ROC)curve was 0.82(P＜0.05),the cutoff values corresponding to the maximal Youden index were 82.5 and 88.6,therefore score of 85 was taken as the median threshold score of judgement.Conclusion The QSACI reflects the post-imlplant outcomes,and it can serve as a tool for people with postlingually deafness and their families to un-derstand the eligbility of CI and the expected outcomes,helping to establish realistic expectations before CI surgery.

Objective:To compare the clinical effect of femoral neck system (FNS) and cannulated compression screw internal fixation in the treatment of femoral neck fractures in young and middle-aged patients.Methods:The databases of CNKI, Wanfang Data Knowledge Service Platform, VIP, Chinese Medical Journal Full-text Database, PubMed, Embase, Web of Science and Cochrane Library were searched. The intraoperative blood loss, intraoperative fluoroscopy times, hospital stay, fracture healing time, Harris hip function score, partial weight-bearing time and complication rate were extracted to compare the clinical efficacy of the two surgical methods. Stata18.0 statistical software was used for meta-analysis.Results:A total of 699 patients from 11 studies were included in this study. Compared with cannulated compression screw internal fixation, the FNS had a shorter operation time [ WMD= -8.54, 95% CI(-14.87, -2.21), P=0.008], fewer intraoperative fluoroscopy times[ WMD= -8.29, 95% CI(-11.45, -5.12), P< 0.001], a shorter fracture healing time [ WMD=-1.59, 95% CI(-2.49, -0.68), P=0.001], a shorter partial weight-bearing time[ WMD=-3.45, 95% CI(-4.43, -2.46), P<0.001], a lower incidence of postoperative complications [ RR=0.41, 95% CI(0.22, 0.76), P= 0.004], and a lower incidence of postoperative nonunion [ RR=0.40, 95% CI(0.18, 0.88), P=0.022]. Meanwhile, the FNS group had more intraoperative blood loss [ WMD=9.53, 95% CI(2.70, 16.35), P=0.006] and a higher Harris hip function score at the last follow-up [ WMD=3.50, 95% CI(2.11, 4.89), P<0.001] than the cannulated compression screw internal fixation group. There were no statistically significant differences in the length of hospital stay [ WMD=-0.48, 95% CI(-0.82, -0.13), P=0.092] or the incidence of femoral head necrosis [ RR=0.57, 95% CI(0.26, 1.24), P=0.159] between the two groups. Conclusion:Compared with cannulated compression screw internal fixation in the treatment of femoral neck fracture in young and middle-aged patients, FNS has more intraoperative blood loss, but it has more advantages in operation time, intraoperative blood loss, intraoperative fluoroscopy times, postoperative fracture healing time, Harris hip function score, partial weight-bearing time, postoperative nonunion rate and postoperative complications rate.
