With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

To perform the phylogenetic characterization of an isolated porcine rotavirus(PoRV)and investigate its pathogenicity in suckling mice and piglets.A G4P[23]genotype PoRV strain JSJR2023 was successfully isolated from the diarrheic piglet feces through propagation in MA104 cells.The viral proliferation kinetics were analyzed using TCID50 assays,followed by complete genome sequencing through Sanger sequencing platforms.Comprehensive genotyping and phylogenetic reconstruction were conducted using MEGA7.0 with maximum likelihood algorithms.Pathogenicity was assessed in the following animal models:5-day-old C57BL/6 mice and 3-day-old piglets.Multidimensional evaluation included clinical monitoring(diarrhea scoring,growth parameters),virological detection,and histopathological analysis of intestinal tissues.The virus strain JSJR2023 could replicate efficiently in MA104 cells,achieving peak titers of 107.5 TCID50/mL.Whole genome genotype analysis showed that the strain belonged to G4-P[23]-I5-R1-C1-M1-A8-N1-T1-E1-H1.Phylogenetic analysis indicated that the VP3 and NSP4 genes of JSJR2023 strain were most closedrelated to human species rotaviruses,suggesting genetic reassortment between human and porcine RV strains.The animal experiments in suckling mice showed that the JSJR2023 strain infection caused diarrhea symptoms,intestinal edema and congestion,and shedding of intestinal villus epithelial cells.The pathogenicity experiments in piglets showed that compared with the control group,the challenged group of pig-lets had severe diarrhea symptoms,accompanied by reduced appetite and listlessness.Post-mortem examination revealed that the intes-tines were significantly thinner,congested,and filled with yellow watery contents.The challenged piglets showed typical pathological changes such as thinning of the intestinal wall and shortening and shedding of intestinal villi.In conclusion,this study successfully iso-lated a human-porcine recombinant G4P[23]PoRV strain and established the infection models in suckling mice and piglets,providing important tools for investigating the pathogenic mechanism of PoRV,evaluating vaccines and developing antiviral drug.

Developing analytical methods for the chemical components of natural medicines remains a challenge due to its diversity and complexity. Miao-Fu-Zhi-Tong (MFZT) granules, an ethnic Yi herbal prescription, comprises 10 herbs and has been clinically applied for gouty arthritis (GA) therapy. Herein, a series of chemical profiling strategies including in-house library matching, molecular networking and MS/MS fragmentation behavior validation based on ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) were developed for qualitative analysis of MFZT granules. A total of 207 compounds were identified or characterized in which several rare guanidines were discovered and profiled into alkyl substituted or cyclic subtypes. Moreover, network pharmacology analysis indicated that MFZT's anti-gout mechanism was mostly associated with the nuclear factor kappa-B (NF-κB) signaling, nucleotide oligomerization domain (NOD)-like signaling and rheumatoid arthritis pathways, along with the synergistic effect of 84 potential active compounds. In addition, a quantitative analytical method was developed to simultaneously determine the 29 potential effective components. Among them, berberine, pellodendrine, 3-feruloylquinic acid, neoastilbin, isoacteoside and chlorogenic acid derivatives at higher concentrations were considered as the chemical markers for quality control. These findings provide a holistic chemical basis for MFZT granules and will support the development of effective analytical methods for the herbal formulas of natural medicines.

Objective:To compare the complications between breast-conserving surgery with free dermal fat graft (FDFG) and traditional breast-conserving surgery (TBCS) in breast cancer patients, and to analyze the influencing factors for the incidence of complications of breast-conserving surgery with FDFG.Methods:The clinical data of 120 breast cancer patients who underwent breast-conserving surgery with FDFG (FDFG group, 50 cases) or TBCS (TBCS group, 70 cases) in Liuzhou People's Hospital from June 2015 to September 2020 were retrospectively analyzed. The incidence of overall complications and various complications between the two groups were compared, the influencing factors of complications in the FDFG group were analyzed, and the cosmetic outcome was evaluated.Results:There was no significant difference between the two groups in age, lymph node status, clinical TNM stage, etc (all P > 0.05). In the FDFG group, the proportions of patients with the longest tumor diameter > 3 cm and tumor in upper inner quadrant were significantly higher than those in the TBCS group [52.0% (26/50) vs. 27.1% (19/70), χ2 = 7.69, P = 0.006; 38.0% (19/50) vs. 15.7% (11/70), χ2 = 7.73, P = 0.005]. The operation time, intraoperative blood loss, postoperative hospital stay and weight of resected tissues in the FDFG group were higher than those in the TBCS group [(251±69) min vs. (213±41) min, (107±29) ml vs. (68±26) ml, (8.8±2.5) d vs. (6.1±1.6) d, (81±26) g vs. (56±20) g], and the differences were statistically significant ( t values were 10.14, 30.58, 22.20, and 14.54, respectively, all P < 0.001). There were no significant differences in the incidence of overall complications, bleeding, infection, or poor wound healing between the two groups (all P > 0.05). The incidence rate fat liquefaction in the FDFG group was higher than that in the TBCS group [14.0% (7/50) vs. 1.4% (1/70), χ2 = 5.53, P = 0.019]. Multivariate logistic regression analysis showed that the weight of FDFG ( OR = 14.056, 95.0% CI 1.764-111.985, P = 0.013) and the thickness of FDFG ( OR = 19.599, 95.0% CI 1.743-220.345, P = 0.016) were independent influencing factors for the incidence of complications in the FDFG group. The percentage of 'excellent' or 'good' cosmetic outcome in the FDFG group was 90% (45/50). Conclusions:Breast-conserving surgery with FDFG can extend the resected area for tumor without increasing the incidence of overall complications and could provide patients a superior cosmetic outcome, but the incidence of fat liquefaction is higher than that of TBCS. The weight and thickness of FDFG are the influencing factors for the incidence of complications of breast-conserving surgery with FDFG.

Objective:To verify the efficacy and safety of daily oral minodronate in postmenopausal women with established osteoporosis.Methods:In this randomized, double-blinded, placebo-controlled trial, 262 postmenopausal women were enrolled. Patients were randomized to receive daily oral minodronate 1 mg with supplements of 500 mg calcium and 200 U vitamin D 3 ( n=130) or placebo ( n=132) with daily supplements of 500 mg calcium and 200 U vitamin D 3, for 48 weeks. The primary endpoint was the average bone mineral density (BMD) change in the lumbar vertebrae 48 weeks post-treatment. Secondary outcome measures was the incidence of vertebral fractures. Safety assessments included the rate of adverse events. Results:At the end of 48 weeks treatment, the average BMD change rate from baseline were: full analysis set results: (3.52±4.82)% in the minodronate group and (2.00±5.74)% in the placebo group; per-protocol set results: (3.99±5.05)% in the minodronate group and (2.07±6.20)% in the placebo group; the differences were all significant (all P<0.05). Vertebral fracture occured in 3 patients (2.3%, 3/132) in the placebo group, and 1 case (0.8%, 1/130) in the minodronate group ( P>0.05). The incidence of adverse events was 71.5% (93/130) in the minodronate group and 78.0% (103/132) in the placebo group ( P>0.05). Conclusion:Minodronate is effective and safe in the treatment of postmenopausal osteoporosis without severe side effects.

Objective:To compare toally endoscopic thyroidectomy(TET) with open thyroidectomy(OT) in the treatment of differentiated thyroid cancer.Methods:Data of 190 patients at Liuzhou People's Hospital from Jul 2017 to Dec 2019 were analyzed. Patients were divided into endoscopic surgery group ( n=95) and open surgery group ( n=95). Results:The operation time and the hospital stay in endoscopic group were longer than that in open surgery group[(153±25) min vs. (116±17) min, (5.56±1.08) d vs.(5.08±1.04) d, t=11.827，3.083， both P<0.05)]. There was no significant difference in intraoperative blood loss [(33±14) ml vs. (37±16) ml, t=-1.851 P>0.05], recurrent laryngeal nerve paralysis, hypoparathyroidism and wound complications (4% vs. 9%, 9% vs. 15%,1% vs. 3%, all P>0.05). There was no significant difference in the number of central lymph node dissection between the two groups (6.12±3.54 vs. 6.35±4.75, t=-0.404, P<0.05). The length of scar in endoscopic group was shorter [(3.03±0.27) cm vs. (6.47±0.53) cm, t=-56.138, P<0.05), and the postoperative cosmetic score evaluated by the patients was higher (8.76±0.75 vs. 7.39±0.76, P<0.05), than those in open group. There were no tumor recurrence nor metastasis in neither group by short term follow-up. Conclusions:TET is similar to OT on clinical curative effectiveness for differentiated thyroid carcinoma while carries a better cosmetic result .
