ObjectiveZheng’s San Qi San (ZSQS) power, a classic traditional Chinese medicine (TCM) formula, is used for treating soft tissue injuries involving muscles, tendons, and ligaments. However, its underlying therapeutic mechanisms remain unclear. This study aimed to screen and identify pharmaceutically active ingredients and their candidate biomolecule targets, and further elucidate the molecular mechanism of ZSQS in the treatment of skeletal muscle injury. MethodsNetwork pharmacology was employed to construct “ZSQS-component-target”, “protein-protein interaction (PPI)” and “active ingredient-core protein-pathway” networks to predict the key active ingredients and potential core targets of ZSQS for skeletal muscle injury. The predicted results were then validated via microarray data from the GEO database. Molecular docking was then performed to assess the binding ability between the screened active ingredients of ZSQS and the candidate core targets. Moreover, liquid chromatography-mass spectrometry (LC-MS) was used for qualitative and quantitative analysis to verify the active components of the drug and ZSQS serum. Finally, an animal model of eccentric exercise-induced skeletal muscle injury and a myotube cell model of oxidative stress-induced injury were established to validate the effects of ZSQS and its interventional effects on the biological functions of critical targets, thereby demonstrating the potential therapeutic mechanism of ZSQS. ResultsAmong the 111 active components identified in ZSQS and their corresponding 204 targets related to the skeletal muscle injury repair process, 14 core targets (including AKT1) and 4 core active components (quercetin, luteolin, kaempferol, and β‑sitosterol) were screened out, while the corresponding metabolites of quercetin, luteolin and kaempferol were detected in the ZSQS serum. Among these targets, 5 candidate genes (IL-6, CASP3, HIF1A, STAT3, and JUN) overlapped with the differential expression screening results with GEO data, and IL-6 was confirmed to be enriched in the PI3K/AKT pathway. Combined with the prediction results of the AKT expression levels, these findings suggest that the phosphorylation level of AKT1 plays a core role in the therapeutic mechanism of ZSQS. Molecular docking analysis further revealed that the PH domain of AKT1 had high binding energy with all 4 core active components, as verified by LC-MS. Finally, animal model studies have shown the promoting effect of ZSQS administration on skeletal muscle injury repair and its possible antioxidant damage mechanism. Cell model studies further demonstrated that ZSQS-containing serum, core active ingredient combination therapy, and quercetin monomer could increase the phosphorylation level of AKT, promote the nuclear translocation of Nrf2, upregulate the expression of downstream antioxidant enzymes (SOD, GPx, and GR), and inhibit the expression of inflammatory factors (IL-6 and TNF-α), thereby alleviating oxidative stress and the inflammatory response. ConclusionZSQS alleviates skeletal muscle injury mainly by activating the AKT/Nrf2 signaling pathway, enhancing cellular antioxidant and anti-inflammatory capabilities. The results of this study provide a scientific basis for the clinical application and modernized development of ZSQS.

Background and aims Alcohol-associated liver disease (ALD) is a leading cause of liver-related morbidity and mortality worldwide, with no currently effective treatment. ALD is caused by excessive lipid buildup, which eventually triggers inflammation and fibrosis in the liver. Activation of hepatic Kupffer cells (KCs) and macrophages drives liver inflammation, which can worsen alcohol-induced liver injury. The autophagy-lysosome system is crucial for macrophages to support their innate immune functions. Transcription factor EB (TFEB) is a key regulator of autophagy and lysosomal biogenesis, but the role of macrophage TFEB in ALD development is unknown. The aim of this study was to evaluate the effects of Gao-binge alcohol consumption on myeloid cell TFEB and elucidate the role of myeloid TFEB in ALD. Methods Two-to-three-month-old male and female LysM Cre− (WT) and LysM Cre+ Tfeb Flox/Flox (f/f) (myeloid-Tfeb KO) mice were subjected to chronic alcohol feeding plus an acute binge following the Gao-binge model. Serum alanine aminotransferase, aspartate aminotransferase, triglycerides, and cholesterol content were determined using biochemical assays. Total hepatic protein content and messenger RNA (mRNA) levels of autophagy-related proteins and inflammatory markers were determined using immunoblotting, immunohistochemistry, and real-time quantitative polymerase chain reaction (RT-qPCR). Isolated hepatic infiltrating macrophages and KCs from mice given intragastric ethanol infusions were analyzed by Western blot for TFEB and autophagy-related protein content. Raw 264.7 macrophages were treated with ethanol, lipopolysaccharide (LPS), and LPS plus ethanol to examine nuclear TFEB translocation using immunofluorescence. Results We found that TFEB levels were higher in macrophage/KC cells than in hepatocytes and cholangiocytes. While ethanol feeding increased serum alanine aminotransferase and aspartate aminotransferase levels, as well as hepatic triglyceride levels, no significant differences were observed between WT and myeloid-Tfeb KO mice. The number of F4/80-positive KCs/macrophages was similar in all four experimental groups, but hepatic neutrophil infiltration increased in alcohol-fed myeloid-Tfeb KO mice. LPS or ethanol alone induced nuclear TFEB translocation only moderately in Raw 264.7 macrophages. Conclusions Our findings suggest that myeloid TFEB is dispensable for alcohol-induced liver injury in mice.

Triptolide （TP）， the core active component of the traditional Chinese medicine Tripterygium wilfordii ， exhibits remarkable pharmacological activities including anti-inflammatory， immunosuppressive and anti-tumor effects， and holds broad application prospects in the treatment of major diseases such as autoimmune diseases and malignant tumors. However， TP has a narrow therapeutic window and causes multi-organ toxicities including liver， kidney and reproductive toxicities， which severely restrict its safe clinical application and new drug development. Therefore， toxicity reduction and efficacy enhancement has become a core scientific problem urgently to be solved in this field. This paper systematically reviews the four core strategies for TP toxicity reduction and efficacy enhancement， including structural modification， dosage form improvement， herbal compatibility， and external therapies of traditional Chinese medicine. Among them， structural modification optimizes the toxic and efficacy characteristics of TP from the molecular structure level， with typica l derivatives including （5 R ）-5-hydroxy triptolide， ZT01， PG490-88， etc. Dosage form modification achieves toxicity reduction and efficacy enhancement via targeted and sustained-controlled drug release of diverse delivery systems. It includes triptolide preparations such as nanoparticles， liposomes， microemulsion gels and liquid crystals， possessing favorable clinical transformation potential. The herbal compatibility and external therapies of traditional Chinese medicine conform to the holistic view of traditional Chinese medicine and have a profound clinical application foundation， but their mechanisms of action are insufficiently elucidated， and they lack unified standardized specifications and high-quality evidence-based proof. In the future， we should rely on multi-omics technology to elucidate the toxic and efficacy mechanisms， integrate technologies to optimize preparations， improve the evaluation system and promote clinical transformation.

Objective The aim was to evaluate the effects of efforts directed toward controlling Oncomelania hupensis snails on small environmental modification projects in Anqing City to provide a reference for comprehensively controlling O. hupensis in hilly areas where schistosomiasis is endemic. Methods Field and retrospective surveys were conducted to collect data using questionnaires. The data from 35 questionnaires on small-scale environmental modification projects in Anqing City and the effects of snail obtained from monitoring forms were sorted. The data were descriptively analyzed using basic information on environmental modifications and investment costs. The Wilcoxon signed-rank test was used to compare snail status before and after environmental interventions. The Friedman test was applied to evaluate the changes in snail populations in the years after environmental intervention. Non-parametric independent sample tests were adopted to compare differences in the effects of different environmental interventions, environmental characteristics, and between project and control areas. Results A total of 35 environments altered from 2017 to 2023, including the creation of 29 ditches,1 dry land, and 5 pond-weirs. The main environmental interventions included hardening of ditches and pond-weirs as well as tilling with intercropping. The average investment costs of mortared rubble masonry hardening and tilling with intercropping were the highest(147.10 yuan/m2)and lowest(4.62 yuan/m2), respectively. The pre-intervention snail-infested area was 78 900 m2, which decreased to 18 100 m2, a decrease of 77.06%. After environmental intervention, the density and rate of living snails significantly decreased on frames with snails(P<0.001). In ditch environments, the smoothness of the ditch walls and the presence of snails in the upper reaches did not significantly decrease the living snail density; however, the presence of cracks on the inner side of the ditches significantly impacted the decline in the rate(P<0.001). No significant difference was found in the rates at which the living snail density or snail frame occurrence decreased among different environmental modification method. The effects of brick masonry, concrete, and mortared rubble masonry on snail control were significantly stronger than those of chemical snail control(P<0.01), whereas no significant difference was found in the decline in these two rates between project areas using other modification method and control areas using chemical snail control. Conclusions Schistosomiasis-prevention-oriented environmental interventions effectively eliminate snails from hilly snail-infested areas. Cost-effective modification method should be selected based on the environmental type, and post-modification monitoring and maintenance must be strengthened to further increase snail control effectiveness.

Objective:To analyze the clinical characteristics and risk factors of postoperative first bite syndrome（FBS） after parapharyngeal space surgery, and to provide evidence-based recommendations for the diagnosis and management of this complication. Methods:A retrospective analysis was conducted on 142 patients undergoing parapharyngeal space surgery from March 2016 to November 2024, including 12 cases of postoperative FBS. Univariate analysis compared differences in tumor location, pathological type, and surgical approach between FBS and non-FBS groups. Multivariate logistic regression identified independent risk factors. A systematic literature review evaluated the preventive value of transoral endoscopic surgery for FBS, followed by proposed clinical optimization strategies. Results:The incidence of FBS was 8.45%（12/142）. Univariate analysis revealed significant associations with: Superior parapharyngeal space tumors（OR=3.21, 95%CI 1.12-9.21, P=0.029）; Schwannoma pathology（OR=4.05, 95%CI 1.35-12.18, P=0.013）; Traditional lateral cervical approach（OR=5.67, 95%CI 1.89-17.02, P=0.002）. Multivariate analysis confirmed lateral cervical approach（aOR=4.98, 95%CI 1.62-15.31, P=0.005） and schwannoma（aOR=3.75, 95%CI 1.22-11.51, P=0.021） as independent risk factors. Literature review suggested lower FBS rates with transoral endoscopic approaches. The overall effect of the drug on FBS is poor. Conclusion:FBS is a frequent complication of parapharyngeal space surgery, significantly associated with tumor location, pathology, and surgical approach. Transoral endoscopic surgery can effectively reduce the risk of FBS through precise anatomical dissection that minimizes sympathetic nerve injury. Minimally invasive approaches are recommended for eligible cases.

OBJECTIVE: To evaluate the effectiveness of minimally invasive reduction and ulna bicortical angulation intramedullary fixation in the management of Bado typeⅠMonteggia fracture in pediatric patients. METHODS: Between August 2018 and August 2020, the clinical data of 15 pediatric patients diagnosed with Bado typeⅠfresh Monteggia fracture were retrospectively analyzed. There were 11 males and 4 females. The left side was implicated in 5 cases, while the right side was involved in 10 cases. The age ranged from 4 to 12 years old. There were a total of 10 cases of upper ulna fractures and 5 cases of middle ulna fractures. Among these, the ulnar fracture line presented as transverse or short oblique in 9 cases, and long oblique or spiral in 6 cases. The pediatric patients underwent treatment utilizing minimally invasive reduction and ulna bicortical angulation intramedullary fixation. The effectiveness of the treatment was assessed based on the Mayo elbow scoring system. RESULTS: The follow-up period for all 15 cases ranged from 6 to 24 months. Among them, the occurrence of needle tail irritation was observed in 3 cases, all of which exhibited satisfactory healing following routine disinfection and dressing change. The other children had no re dislocation of the radial capitulum, no epiphyseal injury, no osteofascial compartment syndrome, elbow instability and other complications. The degree of limitation of daily life, range of motion of joints, pain level and appearance of limbs were recorded at the last follow-up. According to Mayo elbow scoring system, 12 cases were excellent and 3 cases were good. CONCLUSION The minimally invasive reduction and ulna bicortical angulation intramedullary fixation technique is a simple and effective treatment for Bado typeⅠfresh Monteggia fractures in children.

OBJECTIVE: To investigate the clinical efficacy and safety of ultrasound-guided closed reduction and internal fixation using Kirschner wire for the treatment of olecranon fractures of the ulna in children. METHODS: Between January 2019 and January 2021, 13 children with olecranon fracture were treated with ultrasound-guided closed reduction and percutaneous Kirschner wire internal fixation, including 10 males and 3 females. The age ranged from 3 to 14 years old. Children with ulnar olecranon fractures were evaluated using the Gicquel scoring system. The clinical evaluation encompassed postoperative pain, functional status, and range of motion, with a maximum score of 15 points. The radiological assessment contributed an additional 4 points. A cumulative score of more than 18 scores was classified as excellent, more than 17 scores as good, more than16 scores as fair, and less than 16 scores as poor. Clinical assessment:A score of 14 indicates excellent performance, a score of 13 reflects good performance, a score of 12 denotes fair performance, and a score of less than 11 signifies poor performance. RESULTS: A total of 13 patients were followed up, with a duration ranging from 6 to 12 months. According to the Gicquel scoring criteria, the comprehensive evaluation of clinical and radiographic findings yielded 10 excellent and 3 good outcomes. Evaluation based solely on clinical findings resulted in 13 excellent outcomes. CONCLUSION Ultrasound-guided percutaneous cross Kirschner wire fixation for children's olecranon fracture has the advantages of less trauma, rapid recovery, less fluoroscopy, and good recovery of elbow function. The clinical effect is satisfactory.

Testicular histology based on testicular biopsy is an important factor for determining appropriate testicular sperm extraction surgery and predicting sperm retrieval outcomes in patients with azoospermia. Therefore, we developed a deep learning (DL) model to establish the associations between testicular grayscale ultrasound images and testicular histology. We retrospectively included two-dimensional testicular grayscale ultrasound from patients with azoospermia (353 men with 4357 images between July 2017 and December 2021 in The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China) to develop a DL model. We obtained testicular histology during conventional testicular sperm extraction. Our DL model was trained based on ultrasound images or fusion data (ultrasound images fused with the corresponding testicular volume) to distinguish spermatozoa presence in pathology (SPP) and spermatozoa absence in pathology (SAP) and to classify maturation arrest (MA) and Sertoli cell-only syndrome (SCOS) in patients with SAP. Areas under the receiver operating characteristic curve (AUCs), accuracy, sensitivity, and specificity were used to analyze model performance. DL based on images achieved an AUC of 0.922 (95% confidence interval [CI]: 0.908-0.935), a sensitivity of 80.9%, a specificity of 84.6%, and an accuracy of 83.5% in predicting SPP (including normal spermatogenesis and hypospermatogenesis) and SAP (including MA and SCOS). In the identification of SCOS and MA, DL on fusion data yielded better diagnostic performance with an AUC of 0.979 (95% CI: 0.969-0.989), a sensitivity of 89.7%, a specificity of 97.1%, and an accuracy of 92.1%. Our study provides a noninvasive method to predict testicular histology for patients with azoospermia, which would avoid unnecessary testicular biopsy.

OBJECTIVE: To explore the efficacy and apoptosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of acute myeloid leukemia (AML) with ASXL1 mutation. METHODS: The clinical data of 80 AML patients with ASXL1 mutation treated in our hospital from January 2019 to December 2021 were retrospectively analyzed. The clinical characteristics of the patients were summarized, and the therapeutic effect and prognostic factors of allo-HSCT for the patients were analyzed. RESULTS: Among the 80 patients, 38 were males and 42 were females, and the median age was 39(14-65) years. There were 17 patients in low-risk group, 25 patients in medium-risk group and 38 patients in high-risk group. ASXL1 mutation co-occurred with many other gene mutations, and the frequent mutated genes were TET2 (71.25%), NRAS (18.75%), DNMT3A (16.25%), NPM1 (15.00%), CEBPA (13.75%). Among medium and high-risk patients, 29 underwent allo-HSCT, while 34 received chemotherapy. The 2-year overall survival (OS) rate and disease-free survival (DFS) rate of the allo-HSCT group were 72.4% and 70.2%, while those of the chemotherapy group were 44.1% and 34.0%, respectively. The statistical analysis showed significant differences between the two groups (both P < 0.01). Multivariate analysis showed that age at transplantation >50- years and occurrence of acute graft-versus-host disease after transplantation were poor prognostic factors for OS and DFS in transplantation patients. CONCLUSION Allo-HSCT can improve the prognosis of AML patients with ASXL1 mutation.
