The classic formula Mulisan is the 45th of the 93 formulas in the Catalogue of Ancient Classic Formulas （second batch） of Han medicine published by the National Administration of Traditional Chinese Medicine. It consists of Ostreae Concha， Astragali Radix， Ephedrae Radix et Rhizoma， and wheat， with the effect of replenishing qi and stopping sweating. It is a common formula in the clinical treatment with traditional Chinese medicine. This study analyzes the historical evolution， composition， dosage， original plants and their processing methods， decocting method， efficacy， indications， and modern clinical application of Mulisan by tracing， comparative analysis， and bibliometric methods. The results showed that Mulisan firstly appeared in the Pulse Classic written by WANG Shuhe in the Western Jin Dynasty. The formulation idea can be traced back to the Important Prescriptions Worth a Thousand Gold for Emergency in the Tang Dynasty. The herb composition， dosage， efficacy， and indications of Mulisan were first recorded in the Treatise on Diseases， Patterns， and formulas Related to Unification of the Three Etiologies in the Southern Song dynasty. In terms of original plants and their processing methods， Ostreae Concha is the shell of Ostrea rivularis， which should be calcined before use. Astragali Radix and Ephedrae Radix et Rhizoma are the dried roots of Astragalus membranaceus var. mongholicus and Ephedra sinica， respectively， the raw material of which should be used. Wheat is the dried mature fruit of T. aestivum， which can be used without processing， while the stir-fried fruit， being thin and deflated， demonstrates better effect. The composition of Mulisan is Ostreae Concha 8.26 g， Astragali Radix 8.26 g， Ephedrae Radix et Rhizoma 8.26 g， and wheat 7.92 g. The medicinal materials should be ground into coarse powder and decocted with 450 mL water to reach a volume of 240 mL， and the decoction should be taken warm. In modern clinical practice， Mulisan has a wide range of indications， including spontaneous sweating and night sweating caused by Yang deficiency or Qi deficiency. The clinical disease spectrum treated by Mulisan involves endocrine system diseases， neurological diseases， respiratory system diseases， and cancer. This formula plays a significant role in the treatment of internal medicine diseases in traditional Chinese medicine. This study aims to provide a scientific basis for the subsequent research， development， and clinical application of Mulisan.

Objective: To investigate the role of STAT3 phosphorylation in ferroptosis regulation and its impact on cisplatin resistance mechanisms in human osteosarcoma cells． Methods: Human osteosarcoma HOS cells and cispl- atin-resistant HOS / DDP cells were treated with cisplatin ( 0. 5，1，2，4，8，16，32 mg / L) ，the ferroptosis inducer Erastin ( Era) ( 2 μmol / L) ，and / or the ferroptosis inhibitor Ferrostatin-1 ( Fer1) ( 10 μmol / L) ．Cell viability and proliferation were assessed using the Cell Counting Kit-8 ( CCK-8) and colony formation assays，and cell migration was evaluated via a scratch assay．Reactive oxygen species ( ROS) ，intracellular ferrous iron levels，mitochondrial membrane potential，mitochondrial function，malondialdehyde ( MDA) levels，and the reduced glutathione / oxi- dized glutathione ( GSH / GSSG) ratio were measured using commercial kits．The mRNA expression of ferroptosis- related genes was analyzed by quantitative reverse transcription polymerase chain reaction ( RT-qPCR) ．The protein levels of glutathione peroxidase 4 ( GPX4) ，solute carrier family 7 member 11 ( SLC7A11) ，phosphorylated STAT3 ( p-STAT3) ，and total STAT3 were determined by Western blot． Results: With cisplatin treatment，HOS cells ex- hibited decreased cell viability，mitochondrial membrane potential，and GSH / GSSG ratio ( P＜0. 01) ，along with elevated levels of ROS，ferrous ion，and MDA content ( P ＜0. 01) ． The protein levels of GPX4 ( P ＜0. 01) ， SLC7A11，and p-STAT3 also decreased ( P ＜0. 05) ．Coadministration with the ferroptosis inhibitor Ferrostatin-1 ( Fer-1) reversed these aforementioned effects ( P ＜0. 05) ．In HOS / DDP cells，the mRNA levels of ferroptosis- suppressive genes ( GPX4，FTH1，SLC7A11，and AIFM2) were significantly higher than those in HOS cells ( P < 0. 05) ，whereas the expression of ferroptosis-promoting genes ( ACSL4 and PTGS2) was significantly lower ( P < 0. 05) ．The cisplatin-induced reductions in cell viability and mitochondrial membrane potential，as well as the in- creases in ROS，ferrous ion，and MDA levels，were less pronounced in HOS / DDP cells than in HOS cells．The SLC7A11 protein level showed no significant change． However，combined treatment with the ferroptosis inducer Erastin ( Era) resulted in significant decreases in viability，mitochondrial membrane potential，and the GSH / GSSG ratio in HOS / DDP cells ( P＜0. 05) ．Furthermore，the protein levels of p-STAT3，GPX4，and SLC7A11 were also markedly reduced ( P＜0. 05) ． Conclusion The activation of ferroptosis mediated by p-STAT3 enhances cisplatin sensitivity in HOS / DDP cells．

Objectives:To analyze the clinical characteristics of upper cervical vertebrae with dumbbell schwannoma,and to explore its clinical symptoms,imaging features,and treatment plans.Methods:A retro-spective analysis was performed on 14 patients with upper cervical intra-and extraspinal dumbbell-shaped schwannoma admitted to the Spinal Surgery Department of Southern Theater General Hospital from January 2022 to June 2024,including 9 males and 5 females,aged 43.64±11.96 years(25-61 years).According to the location,size,scope of the tumor,and relationship with the surrounding important tissue structure in upper cervical spine,the relevant clinical treatment data were analyzed and the surgical treatment plan was dis-cussed.Cervical X-ray,CT and MRI examinations were regularly performed after surgery to evaluate the con-ditions of complete resection of tumor and recurrence,the stability of the upper cervical spine and whether the internal fixation was loose or broken.The recovery of spinal nerve function and pain improvement were evaluated by the Japanese Orthopaedic Association(JOA)and visual analogue scale(VAS)scores.Results:All the patients underwent complete tumor resection in one stage,and the postoperative JOA score(10.14±1.55 vs 13.86±1.06,P=0.005)and VAS score(2.42±1.29 vs 0.64±0.71,P=0.000)were statistically different from those before surgery.Postoperative tumor histopathology was confirmed as schwannoma in all the 14 patients.The follow-up time was 6 months to 2 years.No recurrence of tumor was found,neurological symptoms were significantly improved,and no upper cervical instability appeared.Conclusions:For patients with intra-and extra-spinal dumbbell-shaped schwannoma in the upper cervical spine,complete resection of the tumor in one stage of posterior approach can be given priority.If the important stable tissue structure of the upper cervical spine is destroyed,upper cervical spine fixation and fusion should be performed to ensure the stabil-ity of upper cervical spine after tumor resection.

Objective: To analyze the timeliness of antir-etroviral therapy (ART) and its influencing factors among newly reported HIV/AIDS cases in Wenzhou City, Zhejiang Province from 2016 to 2023, so as to provide a reference for improving the ART effect of HIV/AIDS cases. Methods: Newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were selected as the research subjects. Demographic information, the situation of the first CD4+ T lymphocyte (CD4 cell) test, baseline CD4 cell count, and ART situation were collected through the Chinese Disease Prevention and Control Information System. The timely rate of ART was analyzed, and the influencing factors for timely ART among HIV/AIDS cases were analyzed using a multivariable logistic regression model. Results: A total of 4 500 newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were included, among which 3 679 were males, accounting for 81.76%, and 821 were females, accounting for 18.24%. The median age was 46.24 (interquartile range, 26.23) years. Among these cases, 3 606 received timely ART, with a timely rate of 80.13%. The timely rate of ART increased from 57.54% in 2016 to 91.97% in 2023 (P<0.05). Multivariable logistic regression analysis showed that unmarried/divorced/widowed (OR=0.769, 95%CI: 0.641-0.922), detainees (OR=0.492, 95%CI: 0.269-0.900), untimely first CD4 cell test (OR=0.278, 95%CI: 0.234-0.330), baseline CD4 cell count ≥200 cells/µL (OR=0.709, 95%CI: 0.595-0.843) or undetected (OR=0.131, 95%CI: 0.080-0.213) were associated with a lower timeliness for ART among HIV/AIDS cases. Conclusion From 2016 to 2023, the timely rate of ART among newly reported HIV/AIDS cases in Wenzhou City showed an upward trend, which was mainly affected by marital status, case source, timeliness of the first CD4 cell test, and baseline CD4 cell count.

BACKGROUND: Without timely and effective rehabilitation, hearing loss may profoundly affect human life quality. China has a large population of hearing-impaired individuals, which imposes a heavy health burden on society. Moreover, this population is projected to increase rapidly owing to China's aging society. METHODS: We used data from a population-representative epidemiological investigation of hearing loss and ear diseases in four Chinese provinces. We estimated the national prevalence using multiple linear regression of the age-group proportions and prevalence in 31 provinces with clustering analysis. We used years lived with disability (YLDs) to analyze the disease burden and forecasted the prevalence of hearing loss by 2060 in China. RESULTS: An estimated 115 million people had moderate-to-complete hearing loss in 2015 across the 31 provinces of China (8.4% of 1.37 billion people). Of these, 85.7% were older than age 50 years (99 million people) and 2.4% were younger than 20 years old (2.8 million people). Of all YLDs attributable to hearing loss, 68.9% were attributable to moderate-to-complete cases. By 2060, a projected 242 million people in China will have moderate-to-complete hearing loss, a 110.0% increase from 2015. CONCLUSIONS The hearing loss prevalence in China is high. Population aging and socioeconomic factors substantially affect the prevalence and severity of hearing loss and the disease burden. The prevalence and severity of hearing loss are unevenly distributed across different provinces. Future public health policies should take these trends and regional variations into account.

Background and Aims:Microsatellite-stable(MSS)colorectal cancer(CRC)generally exhibits poor responsiveness to immune checkpoint inhibitors(ICIs),and effective immunotherapy strategies remain lacking.Anti-angiogenic agents such as bevacizumab(BEV)can improve the tumor immune microenvironment and act synergistically with ICIs.This multicenter real-world study compared the efficacy of different immunotherapy-based combination regimens in patients with MSS/MSI-L/pMMR advanced CRC,aiming to identify the optimal treatment strategy.Methods:A total of 100 patients with MSS/MSI-L/pMMR advanced CRC who received systemic treatment between November 2019 and February 2025 at four tertiary hospitals in Hunan,China,were retrospectively enrolled.Patients were classified into six treatment groups:chemotherapy alone,chemotherapy+targeted therapy,immunotherapy alone,immunotherapy+chemotherapy,immunotherapy+targeted therapy,and immunotherapy+chemotherapy+targeted therapy.The primary endpoints were overall survival(OS)and progression-free survival(PFS),while secondary endpoints were objective response rate(ORR)and disease control rate(DCR).Additionally,among patients receiving immunotherapy,subgroup analysis was performed according to BEV administration.Results:Among all 100 patients,the immunotherapy+chemotherapy+targeted therapy group achieved the highest ORR(32.0%)and DCR(76.0%)and was the only regimen yielding a complete response(CR).Compared with chemotherapy or immunotherapy alone,the triplet regimen significantly improved OS(P<0.05);although PFS improvement did not reach statistical significance,a clear late-stage separation of survival curves was observed.In the immunotherapy subgroup,BEV-containing regimens achieved markedly better outcomes than non-BEV regimens,with DCR of 75.0%vs.48.8%,median OS of 18.9 vs.11.5 months,and median PFS of 13.8 vs.7.2 months(all P<0.001).Cox regression analysis showed that compared with chemotherapy alone,the triplet regimen significantly reduced the risk of death(HR=0.11)and disease progression(HR=0.25)(both P=0.002).Vascular invasion was identified as an adverse prognostic factor for PFS(HR=3.0,P=0.007).Conclusion:This multicenter real-world study demonstrated that combining immunotherapy with chemotherapy and targeted therapy significantly improves DCR and survival outcomes in patients with MSS/MSI-L/pMMR advanced CRC,with BEV-containing triplet regimens providing the most pronounced benefit.BEV may enhance immune responsiveness by modulating the tumor microenvironment and promoting effector T-cell infiltration,offering a promising therapeutic direction for"immune-cold"CRC.Prospective randomized studies are warranted to further validate its clinical value and define appropriate patient populations.
