Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Objective To investigate the mechanism by which artesunate(ART)attenuates intestinal mucosal barrier damage in acute graft-versus-host disease(aGVHD)and the synergistic effect of ART in combination with dexamethasone(DXM)in the treatment of aGVHD mice.Methods The aGVHD mouse model was established by bone marrow haematopoietic stem cell transplantation.The mice were divided into 9 groups,including normal mice control(Ctrl),aGVHD mice(aGVHD),normal mice receiving ART[30 mg/(kg·d)],aGVHD mice receiving low-dose ART[10 mg/(kg·d)],aGVHD mice receiving medium-dose ART[30 mg/(kg·d)],aGVHD mice receiving high-dose ART[50 mg/(kg·d)],aGVHD mice receiving DXM[20 mg/(kg·d)],aGVHD mice receiving ART[30 mg/(kg·d)]and DXM[20 mg/(kg·d)],and aGVHD mice receiving ART[30 mg/(kg·d)]and halved DXM[10 mg/(kg·d)].Survival rate and clinical parameters were assessed.HE staining and Alcian blue-periodic acid-Schiff(AB-PAS)staining were used to observe the histopathological changes in the intestinal mucosa of the mice;Real-time PCR,Western blotting and immunohistochemistry were used to detect the structure of the intestinal mucosal barrier,the T cell differentiation related transcription factors and cytokines,and the key enzymes of energy metabolism.Flow cytometry was used to detect the T helper cell 17(Th17)and regulatory T cells(Treg).Results After 30 days of ART treatment,aGVHD mice showed significant relief of systemic symptoms and increase in survival rate.In aGVHD mice treated with ART,the intestinal mucosal barrier structure was restored,and the intestinal mucosal permeability was reduced.The activity of AMP-activated protein kinase(AMPK)/mTOR pathway was inhibited,and the energy metabolism pattern of T cells was dominated by fatty acid synthesis.The balance of Th17/Treg was restored due to the decrease of Th 17 and the increase of Treg.The effect of ART+DXM treatment on aGVHD mice was comparable to that of DXM treatment alone,and the survival rate of mice was higher.In particular,the recovery of the intestinal mucosal barrier function was most obvious in the mice treated with ART+half-dose DXM.Conclusion ART reduces the immune injury of allo-T cells to the intestinal mucosal barrier by recovering the Th17/Treg balance,thus maintaining the integrity of the intestinal mucosal barrier function.The synergistic effect of ART and DXM combination treatment in aGVHD mice can reduce the incidence of DXM side effects by decreasing the dosage of DXM.

Objective:To evaluate the safety and feasibility of radical hepatectomy after conversion therapy in patients with initially unresectable advanced hepatocellular carcinoma (HCC).Methods:Clinical data of 72 patients with initially unresectable advanced HCC admitted to the Department of Hepatobiliary and Pancreatic Surgery, Affiliated Cancer Hospital of Zhengzhou University and the Department of Hepatobi-liary and Pancreatic Surgery, Henan Provincial People's Hospital from January 2020 to July 2024 were retrospectively collected, including 61 males and 11 females, aged (58.4±9.1) years. The clinicopathological data of the patients, such as tumor characteristics, conversion treatment regimens, perioperative data, and follow-up situations were analyzed to evaluate the therapeutic effect and safety.Results:Among the patients, there were five cases of China liver cancer staging Ⅰb, six cases of Ⅱa, 22 cases of Ⅱb, 32 cases of Ⅲa and sevene cases of Ⅲb. There were 53 patients scored as Child-Pugh A and 19 as Child-Pugh B. Conversion treatment fashion included immunotherapy combined with targeted therapy and immunotherapy plus targeted therapy combined with hepatic arterial chemoembolization or hepatic arteryinfusion chemotherapy. Liver resection after conversion therapy was as follows: 16 cases of right hemihepatectomy, 20 cases of left hemihepatectomy, 11 cases of mesohepatectomy, seven cases of right posterior hepatectomy, 1 case of caudate lobectomy, 17 cases of local resection. Postoperative pathology showed that there were 17 cases of pathologic complete response and 55 cases of pathologic partial response. One patient died of liver failure after surgery, while the rest had no major complications. The postoperative hospital stay was (13.1±5.1) d. The follow-up time was 21.5(10.2, 32.1) months. The multivariate Cox analysis demonstrated that pathologic partial response and adjuvant therapy duration shorter than 5 cycles were identified as independent risk factors-affecting both recurrence-free survival and overall survival in patients with HCC undergoing sequential surgery after conversion therapy (all P<0.05). Conclusion:Sequential surgical resection provides survival benefits for patients with initially unresectable and advanced HCC after conversion therapy, which is a safe and effective therapeutic strategy.

Objective To explore the materials and embolization technique employed in precision superselective transarterial embolization for the treatment of acute renal hemorrhage.Methods The data of 50 patients with acute renal hemorrhage who underwent precision superselective transarterial embolization were retrospectively analyzed.The angiographic findings,embolic materials and embolization methods were collected.The main outcome measures were technical success rate,clinical efficacy and renal function.Results In this study,44 patients had positive angiographic findings.The clinical success rate was 90.9%(40/44)after first precision superselective transarterial embolization.In patients of failure of first embolization,3 patients underwent successful repeated embolization and 1 patient refused repeat embolization.Empirical embolization was carried out among the 6 patients with negative angiographic findings.In 32 patients with complete data for estimated glomerular filtration rate(eGFR),there was no statistical difference before and those measured 7 d after precision superselective transarterial embolization.Conclusion Precision superselective transarterial embolization technique is an effective method for the treatment of acute renal hemorrhage,preserving renal function.

Objective This study aims to systematically evaluate the evidence-based medicine of traditional Chinese medicine(TCM)in the treatment of dry eye,analyze its efficacy and differences compared with modern Western medicine treatments,and provide a scientific basis for clinical application.Methods By searching Chinese and English databases(including CNKI,Wanfang Data,PubMed,Cochrane Library,etc.),we included meta-analyses and systematic reviews of TCM treatments for dry eye.Literature was screened according to strict inclusion and exclusion criteria,and relevant data were extracted and integrated for analysis.The Mantel-Haenszel fixed-effects model was used to calculate the relative risk(RR)and mean difference(WMD),with the effect size expressed as a 95％confidence interval,to analyze the efficacy in-dicators of TCM treatment for dry eye.Results A total of 21 articles were finally included,involving various TCM inter-ventions for dry eye(such as Chinese herbal medicine,acupuncture,and TCM external therapies).The results showed that TCM treatment was superior to Western medicine alone in improving the overall clinical efficacy[RR=1.63,95％CI(1.46,1.81),P＜0.05],prolonging tear film break-up time[MD=2.23,95％CI(1.85,2.60),P＜0.05],and increasing tear secretion[MD=1.49,95％CI(1.04,1.94),P＜0.05].In addition,acupuncture,the combination of Chinese herbal medicine and Western medicine,and TCM external therapies all demonstrated unique advantages in improving dry eye symptoms and tear function.Conclusion TCM treatment for dry eye shows significant efficacy in key indicators such as overall clinical efficacy,tear film break-up time,and tear secretion,with a high level of safety.

Objective To explore the impact of suture configuration and fixation type on the biome-chanical strength of rotator cuff repair,using a factorial design study.Methods Sixteen fresh-frozen porcine shoulder samples were randomized into an anchorless double-row suture bridge transosseous su-tures(DS)group,an anchored double-row suture bridge transosseous-equivalent(DE)group,an an-chorless X-BOX construct transosseous sutures(XS)group,and an anchored X-BOX construct transos-seous-equivalent(XE)group,each of four,according to suture configuration(double-row suture bridge,traditional X-BOX construct)and fixation type(suture anchors,transosseous sutures).Then,their fatigue resistance(first-cycle excursion,gap length difference ratio,and the percentage of ex-posed footprints)and the failure strength(the maximum failure load and the re-tear type)were mea-sured using a biomechanical material testing machine.Results Different suture configurations affected failure strength(F=39.559,P<0.001),with the double-row suture bridge groups(693.07±58.35 N,746.76±138.57 N)showing significantly higher failure strength,compared to the traditional X-BOX groups(462.90±18.91 N,421.43±90.76 N).However,the fixation type did not significantly im-pact failure strength(F=1.161,P=0.302).Moreover,the suture configuration influenced the gap differ-ence ratio(F=7.781,P=0.016),but had no significant correlation with other fatigue resistance indica-tors(P>0.05).Meanwhile,failure strength and fatigue resistance were not correlated with fixation type,and the interaction between suture and fixation type(P>0.05).The incidence of failure types for the four suture configurations was as follows:Type I tendon tear:XS>XE>DS=DE;type II tendon tear:DS>XE>XS=DE;fixing material-related failure:DE>DS=XE=XS.Conclusion The failure strength and gap formation ratio in rotator cuff repair under fatigue loading are influenced by suture configuration,whereas no significant association has been observed with respect to fixation method,whether using transosseous sutures or suture anchors.

Objective To construct a decision support education program for the family members of patients with advanced cancer and to investigate its application effects,so as to improve understanding and acceptance of hospice care for family members of advanced cancer patients.Methods Using the Ottawa Decision Support Framework as a theoretical guide,the program was initially drafted based on a literature review,qualitative interview and expert consultation.From September 2023 to January 2024,a convenience sampling method was used to select patients' families in a tertiary-level hospital in Tianjin as the research subjects,and they were randomly divided into an experimental group and a control group.The experimental group received the decision support education program in addition to routine care,while the control group received routine care.Family members' knowledge about hospice,the scores on the Death Attitude Profile Scale,and their willingness to choose hospice care were compared before and after the interventions.Results The program finally included 4 first-level items,15 second-level items,and 59 third-level items.During the program implementation phase,4 cases withdrew from the study,resulting in 46 cases in the experimental group and 47 cases in the control group.After intervention,the experimental group had higher scores on hospice knowledge and positive attitude towards death than the control group,while scores on negative attitude towards death were lower(P＜0.05);their willingness to choose hospice care for themselves and for the patients was higher than that of the control group(P＜0.05).Conclusion The hospice care decision support education program is scientific,feasible and practical,which can improve the knowledge of hospice care of the family members,improve their attitude towards death,and ultimately improve their willingness to choose hospice care.

Purpose: The optimal reconstruction method following distal gastrectomy has not been elucidated. Since Billroth-II (B-II) reconstruction is commonly associated with increased bile reflux, Braun jejunojejunostomy has been proposed to reduce this complication. Materials and Methods: We retrospectively analyzed 325 patients with gastric cancer who underwent distal gastrectomy with B-II reconstruction between January 2015 and December 2017, comprising 159 patients without Braun anastomosis and 166 with Braun anastomosis.Outcomes were assessed over three years using annual gastroscopy based on the residual food, gastritis, and bile reflux criteria and the Los Angeles classification for reflux esophagitis. Results: In the first postoperative year, the group with Braun anastomosis showed a significant reduction in bile reflux compared to the group without Braun anastomosis (75.9% vs. 86.2%; P=0.019). Moreover, multivariate analysis identified Braun anastomosis as the sole factor associated with this outcome. Additionally, the group with Braun anastomosis had a lower incidence of heartburn (12.0% vs. 20.1%; P=0.047) and reduced use of prokinetics (P<0.001) and acid reducers (P=0.002) compared to the group without Braun anastomosis.However, these benefits diminished in subsequent years, with no significant differences in residual food, gastritis, or reflux esophagitis between the groups. Both groups showed similar body mass index scores and nutritional outcomes over the 3-year follow-up period. Conclusions Although Braun anastomosis offers short-term benefits in reducing bile reflux after B-II reconstruction, these effects are not sustainable. The routine use of Braun anastomosis should be reconsidered, though either approach remains a viable option depending on the patient’s circumstances.
