To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine. For each research direction，key focus areas，expected objectives，and clinical value were further refined，along with the establishment of a scientifically sound priority funding level evaluation system. Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

OBJECTIVE: To assess the association of microribonucleic acid (miRNA) gene polymorphisms with the risk and clinicopathological characteristics of Crohn's disease (CD) and the influence of miRNA gene variants on the response to ustekinumab (UST) treatment among CD patients. METHODS: From January 2018 to February 2025, 312 patients diagnosed with CD and 527 gender- and age-matched normal controls were selected as the study subjects at the Department of Gastroenterology of the Second Affiliated Hospital of Wenzhou Medical University. Genotypes of miR-155 (rs767649), miR-21 (rs13137), miR-124 (rs531564) and miR-146a (rs57095329, rs2431697) were determined with multiplex polymerase chain reaction-ligase detection reaction (PCR-LDR) technique. The patients were divided into different subgroups according to the Montreal Classification Criteria for CD. Harvey-Bradshaw index (HBI) and simplified endoscopic score for CD were respectively applied to assess the clinical and endoscopic disease activity of CD. Unconditional logistic regression model was employed to analyze the distribution of miRNA gene polymorphisms between the two groups, as well as their influence on the clinicopathological characteristics of CD patients. Among them, 185 CD patients received first-line UST treatment, with the first sufficient dose of UST (6 mg/kg) administered intravenously. Based on the changes in HBI at week 8, the response of patients to UST treatment was evaluated. Unconditional logistic regression model was employed to analyze the distribution of miRNA gene polymorphisms between clinically responsive group (the decline of HBI ≥ 3 scores compared to week 0) and non-responsive group. All of the P values were adjusted by Bonferroni correction. This study has been approved by the Medical Ethics Committee of the Second Affiliated Hospital of Wenzhou Medical University (Ethics No.: 2025-K-12-01). RESULTS: No significant difference was found in the distribution of miRNA gene polymorphisms between the two groups (all P > 0.05). The variant genotype (TC+CC) of rs2431697 was more common among patients with terminal ileal-type and ileocolic-type CD than those with the colonic-type CD (OR = 4.98, 95%CI: 1.49~16.68, P = 0.009, adjusted P = 0.045). However, the opposite conclusion was drawn for the homozygous variant genotype (TT) of rs13137 and variant genotype (GC+CC) of rs531564 (OR = 0.37, 95%CI: 0.18~0.76, P = 0.007, adjusted P = 0.035; OR = 0.36, 95%CI: 0.18~0.73, P = 0.004, adjusted P = 0.020). Compared to patients with non-stricturing and penetrating CD, the variant genotype (AG+GG) and variant allele (G) of rs57095329 were more common in those with stricturing and penetrating CD (OR = 4.06, 95%CI: 2.46~6.71, P < 0.001, adjusted P < 0.005; OR = 3.12, 95%CI: 2.06~4.73, P < 0.001, adjusted P < 0.005). However, the frequencies of variant genotype (AT+TT) and variant allele (T) of rs13137 were lower among patients with stricturing and penetrating CD than in those without (OR = 0.25, 95%CI: 0.15~0.41, P < 0.001, adjusted P < 0.005; OR = 0.45, 95%CI: 0.33~0.63, P < 0.001, adjusted P < 0.005). Additionally, the variant genotype (AG+GG) and variant allele (G) of rs57095329 were more common among those with moderately to severely endoscopic activity than those with mildly endoscopic activity (OR = 2.01, 95%CI: 1.19~3.42, P = 0.009, adjusted P = 0.045; OR = 2.04, 95%CI: 1.28~3.25, P = 0.003, adjusted P = 0.015). In total 117 cases had shown clinical response by week 8, while 68 cases showed no response. Compared with t he clinically non-responsive group, the variant genotype (TC+CC) and variant allele (C) of rs2431697 were more common in the clinically responsive group (OR = 3.86, 95%CI: 1.80~8.32, P = 0.001, adjusted P = 0.005; OR = 2.60, 95%CI: 1.34~5.06, P = 0.005, adjusted P = 0.025). However, the variant genotype (TA+AA) of rs767649 was less frequent in the clinically responsive group than the non-responsive group (OR = 0.40, 95%CI: 0.21~0.74, P = 0.004, adjusted P = 0.020). The same conclusion was drawn for the variant genotype (AT+TT) and variant allele (T) of rs13137 when the clinically responsive group was compared with the non-responsive group (OR = 0.30, 95%CI: 0.14~0.63, P = 0.002, adjusted P = 0.010; OR = 0.54, 95%CI: 0.35~0.82, P = 0.005, adjusted P = 0.025). CONCLUSION Genetic polymorphisms of miRNAs are not associated with the risk of developing CD. The miR-146a (rs57095329) variant may increase the endoscopic activity of CD and the risk for stenosis or penetration. However, the miR-146a (rs2431697) variant may increase the risk of ileal involvement. The miR-21 (rs13137) variant may reduce the risk of ileal involvement and the risk of stenosis or penetration. The miR-124 (rs531564) variant may reduce the risk of ileal involvement. Among patients receiving UST treatment, the miR-146a (rs2431697) variant may increase the clinical response by week 8. However, both the miR-155 (rs767649) and miR-21 (rs13137) variants may decrease the clinical response by week 8.

OBJECTIVE: To compare the effectiveness of early versus delayed closed reduction and percutaneous Kirschner wire fixation in the treatment of pediatric supracondylar humerus fractures. METHODS: A retrospective analysis was conducted on 468 children with supracondylar humerus fractures, who were admitted between January 2020 and December 2023 and met the inclusion criteria. Among them, 187 children were treated during 12 hours after injury (early operation group) and 281 were treated after 12 hours (delayed operation group). There was no significant difference between the two groups ( P>0.05) in the gender, age, injury mechanism, fracture side and type, while there was significant difference in interval from injury to operation ( P<0.05). The operative outcomes, including the operation time, intraoperative blood loss, the length of hospital stay, fracture healing time, elbow function assessed by Flynn criteria at 3 months after operation, and complications, were compared. RESULTS: Compared to the delayed operation group, the early operation group demonstrated significantly shorter operation time and less intraoperative blood loss ( P<0.05). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). All children were followed up 3-12 months. The follow-up time was (6.7±2.9) months in the early operation group and (6.9±2.8) months in the delayed operation group, showing no significant difference between the two groups ( P>0.05). There was no significant difference in the fracture healing time between the two groups ( P>0.05). At 3 months after operation, the early operation group exhibited superior Flynn elbow functional outcomes to the delayed operation group ( P<0.05). In the early operation group, there was 1 case of fracture non-union and 3 cases of cubital varus deformity after operation. In the delayed operation group, there was 1 case of nerve injury, 7 cases of fracture non-union, and 12 cases of cubital varus deformity after operation. There was significant difference in the incidence of complications between the two groups ( P<0.05). One case of the early operation group and 10 cases of the delayed operation group underwent secondary operation, showing no significant difference in the incidence of secondary operation between the two groups ( P>0.05). CONCLUSION For pediatric supracondylar humerus fractures, early closed reduction and percutaneous Kirschner wire fixation can reduce operation time, minimize intraoperative blood loss and postoperative complications, and improve the functional recovery compared to delayed operation.

OBJECTIVE: To compare the biomechanical properties of four internal fixation methods in a lower cervical spine injury model using the finite element method. METHODS: Cervical CT data of a 28-year-old healthy adult male were utilized to establish a finite element model of the normal cervical spine and a lower cervical spine three-column injury model. Four internal fixation methods were then applied to the three-column injury model, resulting in four groups:Group A, anterior cervical locked-plate(ACLP) fixation system model(anterior approach);Group B, posterior cervical pedicle screw fixation model (posterior approach);Group C, combined anterior and posterior cervical pedicle screw fixation model; Group D, Novel composite anterior cervical internal fixation model. A 75 N axial compressive load and a 1.0 N·m pure moment were applied to the upper surface of the cervical spine model to simulate flexion, extension, rotation, and lateral bending movements. The intervertebral range of motion(ROM) and stress distribution of the internal fixators under different motion conditions were compared across all models. RESULTS: Compared with the normal model, the reductions in overall intervertebral ROM for each group under flexion, extension, rotation, and lateral bending were as follows:Group A, 24.04°, 23.12°, 6.24°, and 9.06°;Group B, 24.42°, 24.34°, 6.48°, and 9.20°;Group C, 25.43°, 25.29°, 7.17°, and 9.57°;Group D, 24.75°, 25.5°, 6.71°, and 9.12°. The peak stress values of the internal fixators in each group were:Group A, 53.9 MPa, 79.9 MPa, 61.4 MPa, and 80.3 MPa;Group B, 218.3 MPa, 105.4 MPa, 206.6 MPa, and 186.8 MPa;Group C, 40.8 MPa, 97.2 MPa, 47.1 MPa, and 39.4 MPa;Group D, 93.0 MPa, 144.0 MPa, 64.8 MPa, and 106.3 MPa. CONCLUSION The biomechanical properties of the novel composite anterior cervical internal fixation method are similar to those of the combined anterior-posterior fixation method, and superior to both the anterior cervical ACLP plate-screw fixation and posterior cervical pedicle screw fixation methods.

OBJECTIVES: To evaluate the clinical efficacy of human biological dressing (human acellular dermal matrix) transplantation in the management of refractory wounds among middle-aged and elderly patients. METHODS: A retrospective observational study was conducted involving 104 middle-aged and elderly patients (74 males, 30 females; aged 56-95 years) with refractory wounds treated at the First Affiliated Hospital of Wenzhou Medical University from January 2023 to December 2024. Following debridement, wound areas ranged from 1.0 to 48.0 cm². All patients received vacuum sealing drainage for 7 days, followed by human biological dressing transplantation. Subsequently, depending on the wound condition and the patient's preference, autologous skin grafting (ASG) or wound dressing changes were employed to promote wound healing. Outcome measures included: post-human biological dressing coverage of exposed tendons/bones and occurrence of tendon infection/osteomyelitis; survival rate of ASG at postoperative day 7; healing time in patients managed with wound dressing changes alone; patient satisfaction; and changes in pain intensity, sleep disturbance, and anxiety scores assessed before and 1 month after human biological dressing transplantation using the Edmonton Symptom Assessment Scale. RESULTS: After human biological dressing transplantation, 103 patients exhibited robust granulation tissue formation achieving complete coverage of the exposed tendons/bones, with no instances of tendon/bone necrosis, infection, or osteomyelitis. Among these, 51 patients underwent successful ASG at (44.4±13.0) d post-human biological dressing transplantation (success rate 100.00%), 52 patients achieved primary wound healing through dressing changes alone within (62.6±13.4) d post-human biological dressing transplantation. One patient experienced human biological dressing dissolution and detachment due to gluteal wound infection, resulting in non-healing. The overall cure rate was 99.04%. Patient satisfaction survey showed that 95 patients were very satisfied, 8 were satisfied, and 1 was dissatisfied (satisfaction rate 99.04%). Pain, sleep disturbance, and anxiety scores at 1 month post-human biological dressing transplantation were significantly reduced compared to pre-transplantation scores (all P<0.05). CONCLUSIONS Human biological dressing transplantation demonstrate excellent outcomes in treating refractory wounds in middle-aged and elderly patients and can serve as an effective therapeutic strategy for managing refractory wounds.

OBJECTIVES: To evaluate the effectiveness and safety of deucravacitinib in Chinese patients with moderate-to-severe plaque psoriasis. METHODS: This retrospective study included 41 patients with moderate-to-severe plaque psoriasis treated with deu-cravacitinib 6 mg once daily for 16 weeks at the First Affiliated Hospital of Wenzhou Medical University between January and September 2024. Effectiveness was assessed by the psoriasis area and severity index (PASI), static physician's global assessment (sPGA), palmoplantar psoriasis area and severity index (PPASI), modified nail psoriasis severity index (mNAPSI), and dermatology life quality index (DLQI) at baseline, 4, 8, 12 and 16 weeks after treatment. Adverse events during treatment were recorded. Laboratory parameters, including complete blood count, liver and kidney function, electrolytes, and lipids, were assessed at baseline, 8, 16 weeks after treatment to evaluate safety. Univariate and multivariate logistic regression analyses were performed to explore factors associated with achieving PASI75 at week 16, using baseline characteristics as independent variables. RESULTS: Significant reductions from baseline in PASI and DLQI scores were observed from week 4 through week 16 (all P<0.01). Overall response rates for PASI75, PASI90, PASI100, sPGA 0 or 1 grade, and DLQI 0 or 1 point increased progressively over the treatment period. 75, 90, and 100 refer to a score reduction of at least 75%, at least 90%, and 100%, respectively, from baseline. Response rates of PASI75, PASI90, PASI100 for the scalp, limbs, and trunk, PPASI75, PPASI90, PPASI100 for palmoplantar lesions, and mNAPSI75, mNAPSI90 for nail lesions increased progressively over time but with different trends. Scalp lesions improved most markedly from week 4, followed by the limbs, whereas improvements in trunk and palmoplantar lesions were relatively slower. Nail lesions responded more slowly, with only 20% of patients achieving marked improve-ment at week 16. Deucravacitinib demonstrated good tolerability and compatibility with concomitant medications. No severe adverse events were reported, indicating a favorable safety profile. Multivariate logistic regression analysis revealed no significant association between the achievement of PASI75 response at week 16 and patient age, body mass index, disease duration, or baseline PASI, sPGA, or DLQI scores (all P>0.05). CONCLUSIONS In this real world study of Chinese patients with moderate-to-severe plaque psoriasis, deucravacitinib demonstrated favorable effectiveness and safety over 16 weeks of treatment.

OBJECTIVES: To investigate the molecular mechanism underlying Leber hereditary optic neuropathy (LHON) caused by the m.3472T>C (p.Phe56Leu) mutation. METHODS: From a cohort of 1397 LHON patients, three large pedigrees (WZL122, WZ676, WZ706) carrying the m.3472T>C mutation were identified and selected for this study. Immortalized lymphoblastoid cell lines were established from peripheral blood samples obtained from two affected individuals carrying the homoplasmic m.3472T>C mutation (derived from one Han Chinese LHON pedigree) and two genetically unrelated, matched healthy controls. The MitoTool software was used to analyze the complete mitochondrial DNA sequence to determine the haplogroup background, and the conservation of the mtDNA mutation site was evaluated using the MitoMap database. The secondary structure of the ND1 protein was predicted and analyzed using online prediction software. The three-dimensional structure and molecular interaction changes of wild-type and mutant ND1 proteins were visualized and analyzed using PyMOL. Western blotting was performed to determine the expression levels of key proteins. Cellular ATP levels were measured using a chemiluminescence assay. Mitochondrial membrane potential and intracellular reactive oxygen species (ROS) levels were assessed by flow cytometry. RESULTS: mtDNA haplotype analysis showed that the subjects all belonged to the East Asian mitochondrial haplogroup D4. The m.3472T>C mutation results in the substitution of a highly conserved phenylalanine with leucine (p.Phe56Leu) in the ND1 subunit of mitochondrial complex Ⅰ, which may alter the structure and function of ND1. In lymphoblastoid cell lines carrying the m.3472T>C mutation, manifestations of mutant ND1 instability were observed, including reduced ND1 protein levels, diminished mitochondrial ATP production, decreased mitochondrial membrane potential, and increased mitochondrial ROS production. Concurrently, the expression levels of the antioxidant enzymes catalase and SOD2 were elevated (all P<0.01). These findings collectively suggest impaired complex Ⅰ function. CONCLUSIONS The m.3472T>C mutation contributes to the pathogenesis of LHON by disrupting the structural stability of the ND1 subunit in complex Ⅰ, leading to mitochondrial dysfunction.

To ensure the quality of care for inpatients in ophthalmic hospitals, address the complex and variable conditions of postoperative patients, and conduct more comprehensive, accurate and real-time monitoring of patients, an intelligent monitoring system based on computer vision and artificial intelligence has been designed. This system is employed for real-time monitoring of patient health conditions and intelligent care, with primary applications in medical monitoring, rehabilitation therapy, and inpatient care. It comprises intelligent data acquisition devices, smart cameras, continuous physiological data analysis algorithms, AI algorithms, and software. Given the complex and variable conditions of postoperative patients in ophthalmic hospitals, a comprehensive, accurate, and real-time monitoring of patients is required. Therefore, it is necessary to explore a monitoring technology that imposes low physiological and psychological burdens. The intelligent monitoring system can continuously collect patients' physiological parameter indicators and transmit the monitoring data to doctors' workstations or nurse stations after analysis using intelligent algorithms, providing new tools for patient monitoring, disease assessment, risk warning, and more. Furthermore, through the application of computer vision and artificial intelligence technologies, the system can analyze facial expressions, body postures, and other data to identify patients' emotional states and bedridden postures, enabling the timely detection of abnormal situations and implementation corresponding measures. This helps improving the daily work of medical staff, enhance the nursing safety in single-patient rooms in wards, and potentially find applications in the care of critically ill patients and elderly patients, thereby improving nursing efficiency and quality.

The onset of pregnancy is marked by the formation of a zygote, while the culmination of gestation is manifested by the delivery of a fetus. Meanwhile, a successful pregnancy entails a meticulously coordinated sequence of events from embryo implantation to sustained decidualization of the uterus to placental development and childbirth. The decidual reaction, a pivotal process occurring within the endometrium during pregnancy, is finely regulated by sex steroids and cytokines. Notably, fibroblast growth factors (FGFs), particularly FGF2, play a critical role in this physiological cascade. Dysregulated FGF expression may trigger inadequate decidualization, precipitating a spectrum of adverse pregnancy outcomes, including preeclampsia, recurrent implantation failure, and miscarriage. Furthermore, the human decidua, distinct from most mammalian species and similar to great apes, undergoes regular cycles of formation and shedding, independent of the presence of the embryo in the endometrium. This process is also tightly controlled by various FGFs. In this review, we comprehensively compare diverse research decidualization models, delineate the trend of endometrial FGFs during the menstrual cycle, and provide a synopsis of endometrial diseases triggered by FGF dysregulation.
