Esophageal squamous cell carcinoma is the main histological type of esophageal cancer in China, which seriously threatens the health of people. The application of immunotherapy, mainly immune checkpoint inhibitors, has greatly improved the prognosis of patients with esophageal squamous cell carcinoma, but the efficacy of treatment is still limited. Tertiary lymphoid structure (TLS) is an ectopic organized lymphoid structure that accumulates in non-lymphoid organs. Previous studies have found that TLS in esophageal squamous cell carcinoma is associated with better patient outcomes and enhanced immunotherapy efficacy. Based on current researches about TLS in esophageal squamous cell carcinoma, this paper reviews the relationship between TLS and the prognosis and immunotherapy of patients. We hope to provide reference for the precise immunotherapy of esophageal squamous cell carcinoma.

Objective: To understand the awareness of chikungunya fever knowledge and its related factors among medical college students in Baise City, so as to provide a scientific basis to offer relevant courses and special education. Methods: From July to August 2025, 7 286 enrolled medical students were selected by a sampling method from a medical college in Baise City to participate in the questionnaire survey. The questionnaire covered epidemiological characteristics, clinical symptoms, and prevention/control knowledge of chikungunya fever. Statistical analyses including the Chi quare test and multivariate Logistic regression models were performed. Results: The overall awareness rate of chikungunya fever knowledge among the medical students was 18.89%. Among the knowledge items, the awareness rate of "the high incidence season" was the highest (84.05%), while that of "the infectious period" was the lowest (17.80%). Multivariate Logistic regression analysis showed that medical students with female (a OR= 1.37 , 95%CI =1.20- 1.57 ), the age for over 25 years old (a OR=1.76, 95%CI =1.05-2.93), whose father had a middle school educational level (a OR=1.18, 95%CI =1.05-1.31), and majored in preventive medicine (a OR=1.54, 95%CI =1.10-1.67) had relatively higher awareness rates of chikungunya fever knowledge (all P <0.05). In contrast, students of Zhuang ethnicity (a OR= 0.87 , 95%CI =0.76-0.98) and majoring in nursing (a OR=0.74, 95%CI =0.61-0.91) or pharmacy (a OR=0.70, 95%CI =0.52-0.95) had relatively lower awareness rates (all P <0.05). Conclusions The awareness rate of chikungunya fever related knowledge among medical college students in Baise City is relatively low. Schools should take targeted publicity measures to improve medical students awareness.

BACKGROUND:Peripheral nerve axon rupture seriously affects patients' physical function and mental health.Microsurgery,nerve autograft,nerve allograft,fibrin glue and catheter technology are the main treatments for peripheral nerve injury,each of which has its own advantages and disadvantages,but the overall treatment effect is not satisfactory.Despite the clinical success of Schwann cells in promoting axonal regeneration,there are still many challenges in the treatment with Schwann cells,such as slow expansion of Schwann cells,immune rejection,and low survival rate of transplanted cells.OBJECTIVE:To summarize the role and mechanism of Schwann cells in promoting the regeneration of peripheral nerve axons,and the difficulties and challenges of Schwann cells in the process of nerve regeneration treatment.METHODS:PubMed,Medline,WanFang,VIP,and CNKI were searched by computer using the search terms of"Schwann cells,synaptic Schwann cell,macrophage,peripheral nerve axon rupture,Wallerian degeneration,Peripheral nerve axon regeneration,Central nervous system repair"in English and Chinese.Literature related to Schwann cell proliferation and differentiation,promotion of peripheral nerve regeneration,and clinical applications was retrieved from database inception to October 2024,and a total of 95 articles were finally included for review.RESULTS AND CONCLUSION:Schwann cells interact with macrophages,T cells and other cells,to initiate the regeneration process through signaling pathways,including Krox20/C-Jun,NRG-1/ErbB,Notch,MAPK,and PI3K/Akt/mTOR,synthesize and release nerve growth factors,and thus promote regeneration of the peripheral nervous system.Schwann cells have been experimentally demonstrated to have great potential in peripheral nerve repair and are expected to become the key target of therapeutic intervention.However,there are still problems such as difficulties in cell harvest and culture,as well as the occurrence of other diseases during the treatment process.

Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions （Second Batch）. This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution， efficacy， indications， dosage decoctions， and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty， but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma， 619.5 g of Puerariae Lobatae Radix， 413 g of Paeoniae Radix Alba， and 413 g of Glycyrrhizae Radix et Rhizoma， which are ground into coarse powder. Each dose is 12.39 g， and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome， penetrating pathogenic factors， and detoxicating together. Its indications are widely involved in internal medicine， pediatrics， surgery， ophthalmology and otorhinolaryngology， obstetrics and gynecology， sexually transmitted diseases， and other diseases， such as measles， sores， acne， spots， surgical gangrene， red eyes， toothache， chancre， and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated， including rash， pox， macula， numbness， summer diarrhea， dysentery， sha disease， febrile symptoms， spring warmth， winter warmth， and cold pestilence. At the same time， it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications， it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system， nervous system， pediatric-related diseases and syndromes， skin system， hepatobiliary system， and digestive system. It plays a key role in the treatment of epidemic diseases such as measles， chronic hepatitis B， dysentery， and tetanus.

Objective:To explore differences in the efficacy and safety of ruxolitinib in patients with myelofibrosis by age and to identify prognostic factors by analyzing clinical features and characteristics of chromosomes and gene mutations.Methods:This study retrospectively analyzed 188 patients with myelofibrosis who received ruxolitinib in the Department of Hematology, Qilu Hospital, Shandong University from January 1, 2017, to July 1, 2024. According to age at diagnosis, the patients were divided into the middle-aged group (≤55 years), young elderly group (56-65 years), and elderly group (>65 years). Clinical features, the characteristics of chromosomes and gene mutations, and the efficacy and safety of ruxolitinib treatment were compared across the three age groups. Independent factors influencing overall survival were identified through Cox proportional risk regression analysis.Results:Before treatment, the elderly group had more underlying comorbidities, a heavier symptom burden, higher leukocyte count, higher proportion and frequency of JAK2 mutations, and lower proportion of CALR mutations. The incidence of nondriver gene mutations was significantly higher in the young elderly group. After ruxolitinib treatment, the degree of reduction in spleen size did not differ significantly among the three groups. The length of the palpable spleen below the left costal margin reduced by more than 50% from baseline in 50.9% (27/53) of the patients in the middle-aged group, 43.5% (27/62) in the young elderly group, and 45.5% (20/44) in the elderly group ( P=0.720). No significant difference was observed among the three groups in the degree of reduction in Myeloproliferative Neoplasm Symptom Assessment Form (10-item version) score ( P=0.153), with a reduction in total symptom score by more than 50% achieved by 54.0% (27/50), 60.3% (41/68), and 66.7% (34/51) of the patients from the three groups, respectively ( P=0.429). The most common hematological adverse events were anemia and thrombocytopenia, while the most common nonhematological adverse events were electrolyte disturbance, elevated transaminase activity, and pulmonary infection. Multivariate analysis indicated that in ruxolitinib-treated patients with myelofibrosis, poor overall survival was independently predicted by increased age, reduced hemoglobin, percentage of bone marrow blasts ≥ 1%, absence of JAK2 mutations, chromosomal abnormalities, ≥2 high-molecular-risk mutations, and TP53 mutations. Conclusions:Patients with myelofibrosis stratified by age exhibited heterogeneous clinical features and gene mutation profiles but similar efficacy of ruxolitinib treatment and occurrence of adverse events.

Objective To analyze the current status of clinical trial registration of common anorectal diseases in Chinese Clinical Trial Registry(ChiCTR)and the research of TCM.Methods The ChiCTR database was retrieved to collect and organize clinical trials related to hemorrhoids,anal fissures,anal fistulas,perianal abscesses,and perianal eczema.The retrieval time was from the establishment of the database to December 10,2023.Characterization of included registration trials was analyzed.Results A total of 148 registered projects were included,75 of which were TCM-related clinical trials.Among them,134 clinical trials were pre-registered and 121 passed the ethical review.Shanghai,Jiangsu,Guangdong,Beijing and Sichuan accounted for 76.35％of the total number of registrations,and the largest number of registered projects was in Shuguang Hospital affiliated with Shanghai University of Traditional Chinese Medicine.The top 3 funding sources were local finance,self-funding and hospital funding.The registered projects were mainly intervention studies.114 studies used randomized methods and 34 studies were blinded.Conclusion At present,the number of ChiCTR-registered clinical trials on anorectal diseases is on an increasing trend,and the treatment of anorectal diseases with TCM has obvious characteristics.However,there are cases of irregular filling of registration content and uneven regional distribution.

Objective:To explore the correlation between intestinal flora disturbance and the diagnosis,treatment of rheumatoid arthritis(RA),and to provide bioinformatics basis for further research on precise targeted intervention of RA.Methods:Genes related to intestinal flora disorders and RA genes were downloaded from disease database.Correlation between the two diseases was analyzed via bioinformatics approach.PPI network was conducted by STRING,Cytoscape and their plug-ins,and key genes were screened.Key genes were mapped into Coremine Medicinal to identify medicinal chemicals and medicinal herbs.Results:A total of 525 genes shared by intestinal flora disorders and RA were obtained through integrated screening of the disease database,and key genes with the highest degree of protein interaction were finally selected,namely IL-6,IL-1β,TNF-α,IL-10,STAT3,STAT1 and RELA.These related tar-geted genes were mainly involved in biological processes such as negative feedback regulation and antigen stimulation,and mediate molecular functions such as lipopolysaccharide receptor binding and NF-κB receptor binding,which are mainly concentrated in the plasma membrane region.KEGG analysis showed that these related genes were mainly involved in classical signaling pathways such as IL-17 pathway and Toll-like receptor pathway.Through drug prediction,it was found that Astragalus,Scutellaria,Schisandra and Cop-tis in traditional Chinese medicine might be potential drug sources for RA treatment.Conclusion:Bioinformatics method can predict key genes and signaling pathways of intestinal flora intervention in pathogenesis and progression of RA,and predict the Chinese herbs that may target the regulation of flora for treatment of risk factors,which providing a theoretical basis for further exploration of targeted treatment of RA.

Objective:To investigate the clinical efficacy and safety of laser ablation and closure for the treatment of sacrococcygeal pilonidal disease (SPD) and to analyze risk factors for postoperative recurrence in male patients.Methods:A retrospective observational study was conducted to collect clinical data of 369 patients with SPD who underwent laser ablation and closure in the Anorectal Department of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine between March 2019 and December 2024. Perioperative outcomes and postoperative recurrence were analyzed. The cohort included 313 males and 56 females, with 43 patients aged ≤18 years. The median body mass index was 26.3 (IQR: 22.9, 29.6) kg/m2, and the median disease duration was 28 months (IQR: 4, 76). Among them, 218 male SPD patients who underwent surgery received preoperative sex hormone testing. A logistic regression model was used to analyze the risk factors for recurrence.Results:All patients completed the surgery. The median intraoperative ablation energy delivered was 426.8 (IQR: 243.9, 683.9) J, with no occurrence of major intraoperative complications. Postoperatively, a total of 31 patients (8.4%) required analgesic medication. Within the first postoperative week, 12 patients experienced wound oozing/bleeding; hemostasis was achieved by compression alone in 5 cases, while the remaining 7 instances required suture hemostasis after failed compression attempts. No other complications were observed. The median postoperative hospital stay was 6 (IQR: 4, 8) days, and the median time to return to regular work and life was 7 (IQR: 5, 12) days. The wound healing rate was 100%, with a median wound healing time of 35 (IQR: 30, 42) days. Postoperative recurrence occurred in 19 patients (5.1%), all of whom were male. Multivariate logistic regression analysis identified age ≤18 years (OR = 4.764, 95%CI: 2.424-34.905, P = 0.008) and a history of previous SPD surgery (OR = 5.078, 95%CI: 1.431-18.019, P = 0.012) as independent risk factors for recurrence after SPD laser ablation and closure surgery. Conclusion:Laser ablation and closure are safe, effective, and minimally invasive treatments for SPD. However, particular attention should be paid to the risk of recurrence in young male patients and those with a history of previous SPD surgery.

Objective:To evaluate the efficacy of drug-coated balloons (DCB) in hemodialysis patients with peripheral artery disease (PAD) involving infrapopliteal lesions.Methods:A retrospective analysis was conducted on 53 hemodialysis patients (56 limbs, 66 lesions) with infrapopliteal PAD who underwent DCB treatment between Dec 2018 and Dec 2021. The primary outcome was improvement in Rutherford classification, while secondary outcomes included target lesion revascularization (TLR) and wound healing rate. Safety endpoints were all-cause mortality, amputation-free survival, and amputation rate.Results:The mean lesion length was (145.2±78.4) mm, and 87.5% of patients were of Rutherford grade ≥4. The median follow-up period was 14 months. Rutherford classification significantly improved at 3 and 12 months ( P< 0.001). At 12 months, TLR was 16.6%, wound healing rate was 68.6%, amputation-free survival was 73.2%, all-cause mortality was 19.8%, and amputation rate was 8.9%. Multivariate Cox regression indicated that high WIfI risk ( HR=3.936, 95% CI: 1.079-14.355, P=0.038) was an independent predictor of amputation-free survival. Conclusion:DCB is effective and safe for hemodialysis patients with infrapopliteal artery disease, while high WIfI risk predicts poor prognosis.
