Current formulation of objective performance criteria （OPC） in traditional Chinese medicine （TCM） faces methodological challenges， including poor reporting quality， insufficient standardization of methods， limited comparability of study populations， and inadequate consideration of the genetic and environment particularities of ethnic minority populations. In response to these issues， this paper proposes optimization strategies for setting OPC in TCM， with particular attention to ethnic minority medicine. These include improving methodological techniques and statistical descriptions， ensuring transparency in meta-analyses and data sources； standardizing the estimation of point estimates and confidence intervals， and incorporating multidisciplinary expert consensus for value determination； introducing local real-world data from the same period， especially cohort study evidence， to compensate for the lack of high-quality randomized controlled trial data. Through process transparency and dynamic updating mechanisms， the credibility of OPC method can be enhanced， thereby providing methodological support for strengthening evidence-based research capacity in this field.

BACKGROUND:Research suggests that exercise interventions may be more advantageous than pharmacologic treatments or dietary restriction alone for fat loss,but fewer studies have simultaneously examined the effects of training modalities and training cycles on visceral and subcutaneous fat in obese populations. OBJECTIVE:To investigate the impact of training modalities and training cycles on visceral and subcutaneous fat in recessive obesity female college students. METHODS:Sixty-three female college students with hidden obesity(body mass index<24 kg/m2 and body fat content percentage≥30%)were recruited from Zhengzhou College of Commerce and Industry,and were randomly divided into a high-intensity intermittent training group(n=32)and a moderate-intensity continuous training group(n=31)using the lottery method.Subjects in both groups performed exercise training of corresponding intensity on a running platform and ensured that the exercise volume of both groups was equal,3 times per week,every 4 weeks as one training cycle for 16 weeks.Before training and at the end of each training cycle,subjects'visceral fat,subcutaneous fat,and overall fat were measured using the corresponding test devices. RESULTS AND CONCLUSION:The repeated measures F results indicated that the main effects of training cycles on visceral fat area,visceral fat index,abdominal subcutaneous fat thickness,percentage of body fat and body mass index were significant,while the main effects of training modalities were significant for subcutaneous fat thickness in the triceps brachii and scapula regions.All the interaction effects between training modalities and training cycles were significant(P<0.05).Results from the simple effect tests revealed that the significant simple effects of training modalities at the 4th and 12th weeks for visceral fat area and visceral fat index,at the 8th and 12th weeks for subcutaneous fat thickness in the triceps brachii,scapula region,and abdominal regions,and at the 8th week for the percentage of body fat and body mass index.Simple effects of training cycles were significant for all measures within each group.(3)The results of multiple comparison tests indicated that in the high-intensity intermittent training group,visceral fat area,visceral fat index,percentage of body fat,body mass index and abdominal subcutaneous fat thickness decreased sequentially at the 4th,8th,12th,and 16th weeks,and subcutaneous fat thickness of the triceps brachii and scapula decreased sequentially at the 8th,12th,and 16th weeks(P<0.05).In the moderate-intensity continuous training group,visceral fat area,visceral fat index,subcutaneous fat thickness of the triceps brachii and scapula,percentage of body fat and body mass index decreased successively at the 8th,12th,and 16th weeks,while abdominal subcutaneous fat thickness decreased successively at the 4th,8th,12th,and 16th weeks(P<0.05).To conclude,both training modalities and training cycles are factors influencing visceral and subcutaneous fat in recessive obesity female college students.Training modality primarily affects subcutaneous fat in the triceps brachii and scapular region,but the fat loss effects may converge over a longer training cycle;training cycle primarily affects visceral fat area,visceral fat index,abdominal subcutaneous fat,body fat content,and body mass index.

Objective: To understand the characteristics of injury cases in Longhua District, Shenzhen City, Guangdong Province from 2021 to 2024, so as to provide the evidence for the development of injury prevention and control measures. Methods: The data of injury cases in the first visit due to injury in the sentinel hospitals of Longhua District from 2021 to 2024 were collected from the Shenzhen Injury Surveillance System. The time, cause, place, activity, intention, nature, position, severity, and outcome of injury were described. Results: From 2021 to 2024, a total of 167 524 injury cases were reported in Longhua District, with a male-to-female ratio of 1.89∶1. The incidence of injuries was higher in cases aged 30-<45 years (49 957 cases, 29.82%). Injuries mainly occurred from July to August (31 272 cases, 18.67%). The main cause of injury was falls (52 048 cases, 31.07%). Injuries mainly occurred at home (64 110 cases, 38.27%). Leisure activities were the main activities when injuries occurred (79 008 cases, 47.16%). Most of the injuries were unintentional (159 173 cases, 95.02%). The main type of injury was contusion/abrasion (71 900 cases, 42.92%). The main injury site was upper limb (64 247 cases, 38.35%). Most injuries were mild (131 369 cases, 78.42%). The main injury outcome was discharge after treatment, 160 882 cases (96.04%). The second cause of male injury was blunt force injury (30 140 cases, 27.49%), and the second cause of female injury was animal injury (14 648 cases, 25.31%). Fall was the leading cause of injury in people aged 0-<15 years and ≥65 years, and blunt force injury was the leading cause of injury in people aged 15-<65 years. The second place for male injuries was industrial and construction places (23 722 cases, 21.64%), and for female injuries was school/public places (9 644 cases, 16.66%). The first place for injuries in people aged 45-<65 years was in industrial and construction places. The proportions of fractures, moderate injuries, and hospitalizations increased with age (all P<0.05). Conclusions The main injury cases in Longhua District were males and people aged 30-<45 years. July and August were a period of high risk for injuries. People aged 0-<15 years and ≥65 years were the high-risk groups of falls. More attention should be paid to the fracture risk in the elderly.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Since 2017,twelve chimeric antigen receptor gene-modified T lymphocyte(CAR-T cell)products have been approved for the treatment of hematological malignancies,including relapsed/refractory acute B lymphoblastic leukemia(B-ALL),specific subtypes of B cell lymphoma,and multiple myeloma.However,CAR-T cell therapy faces numerous challenges in its clinical application,such as resistance,lengthy production cycles,high individuation and costs in hematological tumors,and tumor heterogeneity/antigen escape,insufficient infiltration capability,immunosuppressive microenvironments,and poor therapeutic response in solid tumors.With the in-depth exploration of tumor immunology and the development of genetic engineering technology,various new strategies have been attempted to enhance the efficacy and generalizability of CAR-T cell therapy.This paper presents a commentary on CAR-T cell therapy,with a focus on key clinical issues and corresponding countermeasures,providing valuable insights for future basic research and clinical transformation of CAR-T cell therapy.

Objective:To explore the clinical efficacy of anterolateral thigh perforator flap (ALTPF) in treatment of extensive wound of Degree IV burns in limbs.Methods:A retrospective analysis was conducted on 9 patients who had extensive wound of Degree IV burns in limbs caused by stove burns admitted to Department of Burns and Plastic Surgery, the 988th Hospital of the Joint Logistics Support Force of the Chinese PLA between January 2017 and January 2024. Among the patients, there were 8 males and 1 female, aged between 36 and 63 years. Three patients had the wound from anterior leg to dorsal foot, 3 from leg down to ankle, 1 from forearm to hand and 2 from arm to forearm. Area of burns ranged from 20 cm × 15 cm to 30 cm × 25 cm, and all patients were treated by free ALTPF. According to whether the main artery at the recipient site was feasible for direct anastomosis with the vessels carried in flap, 4 patients were treated by bilateral parallel ALTPFs, and 5 were treated by unilateral ultra-long internally supercharged ALTPF. A total of 13 ALTPFs were harvested, with individual flap size at 20 cm × 8 cm to 46 cm × 12 cm. Donor sites were directly sutured. Time for flap harvesting, flap survival and wound healing time were records. Scheduled postoperative follow-up was conducted at outpatient clinic and via telephone interviews to evaluate functional recovery. Follow-up assessments included evaluation of flap condition, two-point discrimination (TPD), recovery of joint function at recipient sites, flap appearance and donor site recovery.Results:The time for flap harvest was 1.0 to 4.5 hours. All 13 ALTPFs successfully survived. The time from surgery to healing of recipient sites was 18 to 72 days, and all donor sites healed. Over the postoperative follow-up that lasted for 6 to 34 months, the recipient sites had found with good cosmetic outcomes, without osteomyelitis or deep tissue infection. Four ALTPFs in 2 patients were found swelling, which were revised at 6 months after surgery. Four ALTPFs in other 2 patients had pigment deposition at edges. One ALTPF was scalded, which healed after dressing changes but left with patchy scars. The remaining ALTPFs were soft, elastic, free from pain and well-perfused, with regained protective sensation at S 3. However, all of the ALTPFs failed to detect TPD. Six patients with lower limb injuries were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scoring system: 2 patients were rated as excellent and 4 were rated as good. Three patients with upper limb injuries were evaluated using Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association: 1 patient was rated as excellent and 2 were rated as good. Only linear scars left at the 13 donor sites, with normal blood supply to the distal limbs, and without restrictions in range of motion of knee joints nor muscle strength of quadriceps. Conclusion:The ALTPF offers advantages such as anatomical consistency, reliable blood supply and flexible combination in treatment of extensive wound of Degree Ⅳ burns in limbs. It is an ideal surgical procedure for treatment of large soft tissue defects of extremities.

Objective:To establish a three-dimensional U-shaped residual coordinated attention network (URCA-Net) based on enhanced CT images for small bowel polyp detection and analyze its application effectiveness in intelligent detection of small bowel polyps.Methods:Abdominal CT data of patients with small bowel polyps were collected from the Air Force Medical Center between June 2019 and July 2023. All patients underwent bowel preparation followed by thin-slice spiral CT scanning to obtain enhanced CT arterial phase images. The data were randomly divided into training, validation and test sets in an 8∶1∶1 ratio. The URCA-Net deep learning model was used for small bowel polyp segmentation. The training set was used for model parameter training, the validation set for hyperparameter adjustment and monitoring of model generalization performance and the test set for final unbiased evaluation of the model. An early intelligent detection model for small bowel polyps was constructed, and its performance was evaluated. Evaluation metrics included pixel-level metrics for the segmentation task [Dice Similarity Coefficient (DSC)], as well as sensitivity and precision for polyp detection. A two-stage segmentation strategy was adopted: the first stage segmented the small bowel region to remove external interference, and the second stage performed polyp segmentation within the small bowel region.Results:A total of 78 subjects were included in the study, with an average age of (54±7) years. A total of 23 400 scan images were extracted, including 136 hyperplastic polyps, 298 hamartomatous polyps, 14 adenomatous polyps, and 4 cancerous polyps. On the test set, the average DSC for the first stage (small bowel segmentation) and the second stage (polyp segmentation) was 0.790 and 0.314, respectively. In the second stage task (polyp segmentation based on small bowel region), the polyp segmentation DSC increased to 0.701, with a precision of 0.836 (95% CI: 0.700-0.972) and a sensitivity of 0.759 (95% CI: 0.631-0.888) for polyp detection. Conclusion:The URCA-Net deep learning technique demonstrates good auxiliary diagnostic effectiveness in small bowel polyp detection and can provide a reference for screening and detection of small bowel polyps. The model is capable of generating high-quality segmentation results, which could facilitate evaluating polyp lesion morphology and provide support for downstream tasks such as preoperative navigation and risk prediction.

Objective To investigate the expression levels of microRNA-152-3p(miR-152-3p)and sex determining region-box transcription factor 5(SOX5)in gastric cancer(GC)tissues and their clinical significance.Methods A total of 120 GC patients were selected as study subjects.Re-al-time quantitative polymerase chain reaction(qRT-PCR)was used to detect the expression levels of miR-152-3p and SOX5,and their relationships with the clinicopathological characteristics of GC pa-tients were analyzed.The Kaplan-Meier method was applied to draw survival curves,and the Cox re-gression model was used to screen the prognostic influencing factors of GC patients.Results The ex-pression level of miR-152-3p in GC tissues was lower than that in adjacent non-cancerous tissues,while the expression level of SOX5 was higher than that in adjacent non-cancerous tissues(P＜0.05).The expressions of miR-152-3p and SOX5 in GC tissues were all associated with lymph node metastasis,degree of differentiation,and TNM stage(P＜0.05).The expression level of miR-152-3p was negatively correlated with that of SOX5(r=-0.512,P＜0.05),and there were targeted binding sites between miR-152-3p and SOX5.The 5-year specific survival rate of the low miR-152-3p expression group was lower than that of the high miR-152-3p expression group(60.53％versus 84.09％,x2=7.256,P＜0.05).The 5-year specific survival rate of the high SOX5 expression group was 63.10％,which was lower than 83.33％of the low SOX5 expression group,with a statis-tically significant difference(x2=4.840,P＜0.05).Multivariate Cox regression analysis showed that the expression levels of miR-152-3p and SOX5,as well as the TNM stage,were all independent prog-nostic influencing factors for GC patients(P＜0.05).Conclusion Low expressions of miR-152-3p and high expression of SOX5 are observed in GC tissues,and their expression levels are closely re-lated to clinicopathological characteristics such as TNM stage and patients' prognosis.
