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 report a new technique that combines microfracture surgery under local anesthesia with injection of platelet-rich plasma (PRP) at the fracture site, so as to improve fracture healing rates. [Methods] Data from patients who visited our hospital from March 2020 to June 2023 and underwent the treatment for delayed union of limb fractures were retrospectively analyzed. Under local infiltrative anesthesia, with the assistance of a C-arm X-ray machine or ultrasound, percutaneous loosening was done at the fracture site and the medullary cavity, followed by cortical drilling around the fracture. The previously prepared PRP was then injected locally at the fracture site. Patients were followed up and their postoperative recovery was recorded. [Results] All patients were followed up, and the fracture healing rate was 94.12% (16/17), with an average healing duration of (5.88±2.50) months. None of the patients experienced any neural or vascular injuries, nor adverse events such as wound infections or osteomyelitis. Before the operation and at the last follow-up, the patients' pain visual analogue scores were (5.12±1.11) vs (0.71±1.21) respectively. The postoperative VAS scores showed a significant decrease compared to preoperative values (P<0.05). The excellent and good rate for limb function on the affected side was 88.24% (14/17) at the last follow-up, which was a significant increase from 0.00% before surgery (P<0.05). [Conclusion] The injection of PRP at the fracture site combined with microfracture surgery at the fracture site is minimally invasive, simple to perform, and well-accepted by patients. It has demonstrated some clinical efficacy in treating delayed fracture healing.

Objective:To evaluate the effect of transient receptor potential vanilloid type 1 (TRPV1) gene polymorphism on the postoperative analgesic efficacy of alfentanil in patients undergoing radical mastectomy.Methods:In this prospective study, adult female patients diagnosed with breast cancer who underwent surgical treatment at the First Affiliated Hospital of Zhengzhou University were selected as case group ( n=162), while age-matched healthy adult females were selected as control group ( n=80). All subjects had a body mass index of 18-30 kg/m 2. The genotype and allele frequencies of TRPV1 rs8065080 and rs222747 were compared between the two groups, and the consumption of alfentanil and requirement for rescue analgesia within 48 h after surgery were recorded in breast cancer patients with different TRPV1 rs222747 genotypes. Results:Three genotypes of CC, GC, and GG were detected at rs222747 locus of TRPV1 gene, and there was no significant difference in the genotype distribution between the two groups ( P>0.05). Three genotypes of CC, TC and TT were detected at rs8065080 locus of TRPV1 gene, and there was significant difference in the genotype distribution between the two groups ( P<0.05). There was no significant difference in the basic data of patients with different genotypes of TRPV1 gene rs222747 locus ( P>0.05). There were significant differences in the consumption of alfentanil during 0-24 h after surgery and during 24-48 h after surgery and rate of rescue analgesia within 48 h after surgery among patients with different genotypes of TRPV1 gene rs222747 locus ( P<0.05). Conclusions:The polymorphism at the TRPV1 gene rs222747 locus can influence the postoperative analgesic efficacy of alfentanil in breast cancer patients undergoing radical mastectomy, suggesting that genetic factors may be one of the reasons for the inter-individual variability in alfentanil efficacy.

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 explore the clinicopathologic features differences between tall cell variant of papillary thyroid cancer (TCV-PTC) and PTC with tall cell features (PTC-TCF) and the factors influencing efficacy of 131I therapy in patients with TCV-PTC and PTC-TCF. Methods:A retrospective analysis was conducted on 84 patients (28 males, 56 females, age 43.5(35.0, 55.0) years) with pathologically confirmed TCV-PTC or PTC-TCF and who were treated with 131I therapy from January 2018 to June 2023 in the Department of Nuclear Medicine, the Affiliated Hospital of Qingdao University. The patients were divided into structural incomplete response (SIR) group and non-SIR group according to 131I treatment response. Data differences were analyzed by Wilcoxon rank sum test, Fisher exact test, or Mann-Whitney U test. Variables with P<0.1 were enrolled in logistic multivariate regression analysis. The ROC curve was used to obtain the cut-off value of stimulated thyroglobulin (sTg). Results:A total of 37 patients with non-SIR and 6 patients with SIR were found in TCV-PTC group ( n=43), and 33 non-SIR and 8 SIR cases were found in PTC-TCF group ( n=41). Univariate analysis revealed that sTg differed significantly between non-SIR patients and SIR patients in TCV-PTC group ( Z=-2.81, P=0.003), while no significant differences observed for sex, age, multifocality, capsular invasion, T stage, N stage, B-Raf proto-oncogene, serine/threonine-protein kinase (BRAF) V600E mutation, initial recurrence risk, number of metastatic lymph nodes, maximum tumor diameter ( Z values: from -0.74 to -0.11, all P>0.05). In TCV-PTC group, sTg also differed significantly between non-SIR patients and SIR patients ( Z=-4.40, P<0.001), while the other clinical factors above and the proportion of tall cells showed no significant difference ( Z values: from -1.90 to -0.22, all P>0.05). The logistic regression analysis confirmed sTg as an independent risk factor of SIR in both TCV-PTC group (odds ratio ( OR) = 25.156, 95% CI: 2.245-281.812, P=0.009) and PTC-TCF group ( OR=19.214, 95% CI: 2.537-145.502, P=0.004). The ROC curve indicated that the cut-off value of sTg for predicting SIR was 20.75μg/L in TCV-PTC group and 18.55μg/L in PTC-TCF group. Conclusions:sTg is the independent risk factor for predicting the poor prognosis of patients with TCV-PTC (sTg≥20.75μg/L) and PTC-TCF (sTg≥18.55μg/L). However, other clinical characteristics show no statistical difference between TCV-PTC group and PTC-TCF group, suggesting that the invasiveness of PTC-TCF may not be lower than that of TCV-PTC, which close attention should be paid to in clinical practice.

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.
