OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia （TGP） in the treatment of systemic lupus erythematosus （SLE）. METHODS Randomized controlled trial （RCT） about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed， Embase， Cochrane Library， Web of Science， CNKI， VIP， Wanfang Data， and CBM. The search period spanned from the inception of each database to June 1， 2025. After literature screening， data extraction， and quality assessment of the included studies， Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs， involving 1 318 patients， were included. Meta-analysis results showed that compared with western medicine alone， TGP combined with western medicine significantly improved clinical efficacy [OR＝4.96， 95%CI（3.41， 7.23）， P＜0.000 01]， complement 3 [MD＝0.18， 95%CI （0.13， 0.23）， P＜0.000 01] and complement 4[MD＝0.08， 般021） 95%CI （0.04， 0.11）， P＜0.000 01]， and reduced the levels of immunoglobulin G （IgG） [MD＝－3.10， 95%CI （－3.59，－2.62）， P＜0.000 01]， IgA [MD＝－0.68， 95%CI （－0.78， －0.58）， P＜0.000 01]， IgM [MD＝－0.43， 95%CI （－0.53，－0.34）， P＜0.000 01]， systemic lupus erythematosus disease activity index （SLEDAI） [MD＝－1.59， 95%CI （－2.20， －0.99）， P＜0.000 01]， recurrence rate [OR＝0.23， 95%CI （0.13， 0.42）， P＜0.000 01] and the incidence of adverse drug reactions [OR＝ 0.54， 95%CI （0.36， 0.82）， P＝0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients， promote the restoration of immunoglobulins and complements， reduce SLEDAI and recurrence rate and has good safety.

Objective: Spinal stenosis and degenerative spinal disorders are increasingly prevalent and have a substantial impact on quality of life. Surgical decompression, performed using either open microscopic or endoscopic approaches, remains a cornerstone of management for these conditions. This study examines evolving trends in single-level lumbar spinal decompression procedures performed at a tertiary academic hospital in Singapore. Methods: A retrospective observational study was conducted involving 588 patients who underwent single-level spinal decompression between 2021 and 2024, including endoscopic spine surgery (ESS; n=364) and microdecompression (n=224). Primary outcome measures were changes in 36-Item Short Form Health Survey (SF-36) and visual analogue scale (VAS) scores at 3 months, 6 months, and 2 years postoperatively. Secondary outcomes included length of hospital stay, reoperation rates, and operative time. Patient demographics, spinal level and pathology characteristics, surgical techniques, and postoperative outcomes were analyzed. Difference-in-differences (DID) analysis was used to compare outcomes between the 2 groups. Results: Both groups demonstrated significant postoperative improvements in SF-36 and VAS scores. At 2 years, Short Form Health Survey physical function (SFPF) scores improved in the endoscopic group (mean difference [MD], 18.6; standard deviation [SD], 21.7; p=0.064) and in the open microscopic group (MD, 36.7; SD, 20.9; p=0.007), with a non-significant DID of -18.1 (p=0.155). No DID comparisons across SF-36 domains reached statistical significance. Mean operative time for endoscopic procedures decreased from 249 minutes in 2022 to 145 minutes in 2024, reflecting a procedural learning curve. Surgeons with higher endoscopic caseloads exhibited greater improvements in functional outcomes. Conclusion Both endoscopic and open microscopic decompression achieve comparable short- and long-term clinical outcomes. ESS provides similar effectiveness while being associated with shorter recovery periods and reduced hospital stay. Further research is warranted to identify factors contributing to incomplete symptom resolution or the need for revision surgery.

Objective To compare the effects of main artery clamping(MAC)and selective artery clamping(SAC)strategies on postoperative renal function in patients with chronic renal insufficiency undergoing robot-assisted partial nephrectomy.Methods A retrospective cohort study was conducted on 231 patients with preoperative chronic renal insufficiency[eGFR<90 mL/(min·1.73 m2)with renal injury markers or eGFR<60 mL/(min·1.73 m2)]who underwent robot-assisted partial nephrectomy in the Department of Urology of the First Affiliated Hospital of Army Medical University from February 2018 to February 2024.According to intraoperative renal artery clamping strategy,they were divided into a MAC group(n=129)and a SAC group(n=102).Preoperatively,individualized renal artery clamping strategies were developed using a machine learning-based multimodal holographic 3-D reconstruction technique.Serum creatinine(Scr)level was measured at 3 d and 3 months after surgery,and estimated glomerular filtration rate(eGFR)was calculated using the chronic kidney disease epidemiology collaboration equation(CKD-EPI)formula.Renal dynamic imaging with 99mTc-DTPA or 99mTc-MAG3 was used to assess the GFR of the affected kidney.Results At 3 d after surgery,the decrease in GFR of the affected kidney was significantly lower[(8.3±7.7)vs(16.0±10.2)mL/(min·1.73 m2),95%CI:-10.2～-5.2,P<0.001]in the SAC group than the MAC group.Scr increment analysis showed that the SAC group exhibited notably lower Scr increase[8.2(2.5,18.7)vs 15.5(5.8,28.3)μmol/L,95%CI:-12.3～-1.8,P=0.027],and milder eGFR decline[3.0(0.5,7.8)vs 7.5(2.0,14.3)mL/(min·1.73 m2),95%CI:-6.2～-0.8,P=0.015].And,in 3 months after surgery,the SAC group had lower Scr level[(89.2±23.1)vs(95.3±22.1)μmol/L,95%CI:-11.9～-0.3,P=0.042],and higher GFR of the affected kidney[(33.5±10.5)vs(26.1±10.9)mL/(min·1.73 m2),95%CI:4.6～10.2,P<0.001].Conclusion For patients with chronic renal insufficiency undergoing robot-assisted partial nephrectomy,SAC strategy is superior to MAC strategy in protecting postoperative renal function without increasing surgical risk.

The construction of first-class universities and disciplines is a major strategic initiative of the Communist Party of China Central Committee and the State Council,and an important task for building a world-class higher education powerhouse.Forensic medicine was officially listed as a first-level discipline under the medical category in 2022,presenting unprecedented historical opportunities for the development of forensic medicine.Facing this significant strategic opportunity,this paper sorts out the disciplinary system of forensic medicine,carries out forward-looking planning for the develop-ment of the discipline,and looks forward to the development vision of the discipline:(1)Establish an organically connected three-stage forensic medicine talent training system to cultivate applied and innovative talents that meet the needs of China's socialist modernization construction;(2)Establish a unified standardized forensic practice qualification examination system,organically connect talent training with professional qualification examination,and optimize the professional development path of forensic medicine;(3)Widely intersect,integrate and transform forensic medicine with other multiple disciplines,expand and enrich the second-and third-level disciplinary systems of forensic medicine,and build a world-class forensic medicine discipline with Chinese characteristics.

Objective:To observe the effects of early enteral nutrition(EN)intervention on neurological function,nutritional status,and inflammatory stress response in patients with severe traumatic brain injury.Methods:This study was a single-center prospective study,68 patients with severe traumatic brain injury were divided into control group[received parenteral nutrition(PN)intervention,n=34]and observation group(received early EN intervention,n=34)according to the envelope lottery method.The improvement of neurological function[serum central nervous system specific(S1 00(3)protein,national institutes of health stroke scale(NIHSS)score,myelin basic protein(MBP)],nutritional status[transferrin(TRF),total protein(TP),albumin(ALB)and prealbumin(PA)],inflammatory stress indicators[C-reactive protein(CRP),procalcitonin(PCT),glutathione peroxidase(GSH-PX),malondialdehyde(MDA)],daily living activity ability,quality of life,and incidence of complications between two groups were compared.Results:Compared with the control group after intervention,the observation group had lower NIHSS scores,S100[3 protein,MBP,CRP,PCT and MDA,had higher TRF,TP,ALB,PA,GSH-PX,improved Barthel index and world health organization quality of life assessment scale-100(WHOQOL-100)score(P＜0.05).There was no difference in the incidence of complications between the two groups(P＞0.05).Conclusion:Early EN intervention in patients with severe traumatic brain injury can effectively improve neurological function,nutritional status,and reduce the body's inflammatory stress response,which is worthy of clinical reference and application.

Paraganglioma（PGL）is an extra-adrenal catecholamine-secreting endocrine tumor. We reported a young female patient who was admitted to the hospital with right flank pain and diagnosed with right retroperitoneal PGL with Mayo Ⅳ inferior vena cava tumor thrombus（double tumor thrombus）. After multidisciplinary consultation，right retroperitoneal PGL resection，right nephrectomy，inferior vena cava Mayo Ⅳ tumor thrombus resection and reconstruction were performed. Postoperative pathology showed that the primary tumor and inferior vena cava tumor thrombus was consistent with PGL. Genetic testing revealed a heterozygous germline nonsense mutation at c.69_70delinsTT（p.Q24*）locus of the SDHB gene in the patient. His mother was a carrier of the gene，but his father and sister did not carry the mutation. The patient recovered smoothly after surgery.

Pathological cardiac hypertrophy is an early and significant cardiac structural charac-teristic that contributes to the onset and progression of heart failure(HF).Its mainly structural feature is the abnormally enlarged cardiomyocyte.Effective intervention targets for abnormally en-larged cardiomyocyte remain to be identified.Previous studies have shown that the cellular shape and size can be regulated by the actin related protein 2/3(Arp2/3)complex,which is an actin-binding protein complex involved in the actin nucleation and assembly.However,the roles of the Arp2/3 complex in cardiomyocyte hypertrophy remain unknown.Here our study identifies its no-vel roles in the occurrence and development of cardiomyocyte hypertrophy.We found that mRNA levels of all subunits from the Arp2/3 complex are significantly upregulated(P<0.05)in the an-giotensin II(Ang Ⅱ)-induced neonatal rat primary and H9c2 cardiomyocyte hypertrophy.Fur-ther studies showed that siRNA-directed ARPC2 silencing inhibits the reactivation of fetal genes and enlargement of cardiomyocyte area induced by Ang Ⅱ in neonatal rat primary cardiomyocytes(NRCMs)and H9c2 cells(P<0.05).In addition,the upstream activators of the Arp2/3 com-plex including SH3 protein interacting with Nck,90 kD(SPIN90)and Ras-related C3 botulinum toxin substrate 1(Rac1)/WASp family Verprolin-homologous protein-2(WAVE-2)are upregu-lated(P<0.05)in Ang Ⅱ-induced neonatal rat primary and H9c2 cardiomyocyte hypertrophy,indicating the excessive activation of the Arp2/3 complex.We further show that CK666,a specif-ic Arp2/3 complex inhibitor,prevents the reactivation of fetal genes and the enlargement of car-diomyocyte area induced by Ang Ⅱ in NRCMs and H9c2 cells(P<0.05).Our results reveal that the Arp2/3 complex plays a crucial role in Ang Ⅱ-induced cardiomyocyte hypertrophy,which is beneficial to further studies about the molecular mechanisms by which the Arp2/3 complex regu-lates pathological cardiac hypertrophy.

Objective:To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) complicated by fatigue.Methods:COPD patients enrolled in the RealDTC study from June 2023 to March 2024 were included. Demographic data, history of acute exacerbations in the past year, smoking status, biofuel exposure, occupational exposure, modified Medical Research Council (mMRC) dyspnea score, COPD Assessment Test (CAT) score, forced expiratory volume in the first second predicted of percentage (FEV 1%pred), forced expiratory volume in one second (FEV 1)/forced vital capacity (FVC), and comorbidities (bronchial asthma, bronchiectasis, tuberculosis, cardiovascular disease, diabetes mellitus) were collected. Fatigue was evaluated using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire, with a score ≤43 defined as fatigue. Patients were divided into fatigue and non-fatigue groups, and multivariate regression analysis was used to screen factors associated with fatigue in COPD patients. Results:A total of 597 COPD patients were included, of which 280(46.9%) had fatigue symptoms. Compared with non-fatigue patients, fatigue patients had lower FEV 1%pred, FEV 1/FVC, and body mass index (BMI), higher CAT and mMRC scores, and a higher proportion of occupational exposure, bronchiectasis, and treatment with long-acting β 2-agonists (LABA)/long-acting muscarinic antagonists (LAMA)/inhaled corticosteroids (ICS) (all P<0.05). Multivariate regression analysis showed that high CAT score ( OR=2.312, 95% CI: 1.366-3.911), high mMRC score ( OR=1.484, 95% CI: 1.053-2.091), occupational exposure ( OR=1.513, 95% CI: 1.082-2.116), comorbid bronchiectasis ( OR=2.452, 95% CI: 1.102-5.457), low BMI ( OR=0.935, 95% CI: 0.891-0.981), and high CAT-energy score ( OR=1.301, 95% CI: 1.149-1.473) were risk factors for fatigue in COPD patients. The CAT-energy score was highly correlated with the FACIT-F score ( r=0.260, P<0.001), and a CAT-energy score ≥2 could preliminarily screen COPD patients with fatigue. Conclusions:COPD patients with comorbid fatigue have a heavy symptom burden, are more likely to have a history of occupational exposure and bronchiectasis, and the CAT-energy score is of great reference value for screening COPD patients with fatigue.

Objective:To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) complicated by anorexia.Methods:This cross-sectional study included patients registered in the RealDTC study from May 2023 to December 2023. Demographic data, COPD Assessment Test (CAT) score, modified Medical Research Council (mMRC) dyspnea questionnaire score, Clinical COPD Questionnaire (CCQ) score, forced expiratory volume in one second (FEV 1), forced expiratory volume in the first second predicted of percentage (FEV 1%pred), FEV 1/forced vital capacity (FVC), Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade, GOLD group, number of acute exacerbations and hospitalizations in the past year, and score of the Functional Assessment of Anorexia Cachexia Therapy-Anorexia/Cachexia Subscale-12 (FAACT-A/CS-12) were collected. Patients with a FAACT-A/CS-12 score ≤30 were diagnosed as having anorexia. Multivariate logistic regression analysis was used to evaluate the influencing factors of anorexia in COPD patients. Results:A total of 617 COPD patients were included, of whom 109(17.7%) had anorexia. Compared with non-anorexia patients, COPD patients with anorexia had higher age, CAT, mMRC and CCQ scores, and more acute exacerbations and hospitalizations in the past year, while body mass index, FEV 1, FEV 1%pred and FEV 1/FVC were lower (all P<0.05). The proportions of patients with primary education or below, GOLD 3-4 grade and GOLD E group were higher in COPD patients with anorexia (all P<0.05). Logistic regression analysis showed that a CAT score of 10-<20 [odds ratio ( OR)=4.017, 95% confidence interval ( CI): 1.673-59.645], a CAT score of 20-<30 ( OR=9.686, 95% CI: 3.777-24.842), a CAT score of ≥30 ( OR=78.286, 95% CI: 7.654-800.689) and ≥1 hospitalization in the past year ( OR=2.050, 95% CI: 1.292-3.254) were independent risk factors for anorexia in COPD patients (all P<0.05). Conclusions:COPD patients with anorexia have poor lung function, high symptom burden and high risk of acute exacerbation. Clinicians should pay attention to the management of COPD patients with anorexia and take corresponding intervention measures.
