After continuous development and improvement, lung transplantation has become the preferred means to treat a variety of benign end-stage lung diseases. However, the field of lung transplantation still faces many challenges, including shortage of donor resources, preservation and maintenance of donor lungs, and postoperative complications. Lung tissue samples removed after lung transplantation are excellent clinical resources for the study of benign end-stage lung disease and perioperative complications of lung transplantation. However, at present, the collection, storage and utilization of tissue samples after lung transplantation are limited to a single study, and unified technical specifications have not been formed. Based on the construction plan of the biobank for lung transplantation in the First Affiliated Hospital of Xi'an Jiaotong University, this study reviewed the practical experience in the collection, storage and utilization of lung transplant tissue samples in the aspects of ethical review, staffing, collection process, storage method, quality control and efficient utilization, in order to provide references for lung transplant related research.

Objective To investigate the clinical effects of different right lung volume reduction techniques when the donor lung is oversized and mismatched with the recipient. Methods Clinical data of 10 recipients who underwent right lung volume reduction lung transplantation at the First Affiliated Hospital of Xi'an Jiaotong University from October 2022 to June 2024 were collected, including gender, age, primary disease type, and type of transplantation. A retrospective analysis was performed on postoperative complications within 90 days, duration of mechanical ventilation, hospital stay, and survival status to explore the impact of different volume reduction techniques on the survival rate of lung transplant recipients. Results A total of 10 right lung volume reduction recipients were included in this study, with 2 cases of upper lobe reduction, 7 cases of middle lobe reduction, and 1 case of lower lobe reduction. Three recipients developed airway complications (one each with upper, middle, and lower lobe reduction). The 30-day survival rate was 90% and the 1-year survival rate was 70%. One recipient with upper lobe reduction died of septic shock during the perioperative period, one with lower lobe reduction died of airway anastomotic fistula 2 months after surgery, and one with middle lobe reduction died of renal insufficiency 1 year after surgery. All 7 recipients with middle lobe reduction successfully passed the perioperative period, with one case of airway anastomotic stenosis (1/7). The average duration of mechanical ventilation was 71 hours, and the average hospital stay was 26 days. The 30-day survival rate was 7/7, and the 1-year survival rate was 6/7. Conclusions Middle lobe reduction in right lung transplantation surgery has the advantages of low incidence of airway complications, good safety, and minimal loss of lung function, and may be a better right lung volume reduction option with potential for application.

To elucidate the mechanism by which steaming affects the quality of Curcuma kwangsiensis root tubers, methods such as LSCM, RVA, dual-wavelength spectrophotometry, LF-NMR, and LC-MS were employed to qualitatively and quantitatively detect changes in starch gelatinization characteristics, water distribution, and material composition of C. kwangsiensis root tubers under different steaming durations. Based on multivariate statistical analysis, the correlation between differences in gelatinization parameters, water distribution, and terpenoid material composition was investigated. The results indicate that steaming affects both starch gelatinization and water distribution in C. kwangsiensis. During the steaming process, transformations occur between amylose and amylopectin, as well as between semi-bound water and free water. After 60 min of steaming, starch gelatinization and water distribution reached an equilibrium state. The content of amylopectin, the amylose-to-amylopectin ratio, and parameters such as gelatinization temperature, viscosity, breakdown value, and setback value were significantly correlated(P≤0.05). Additionally, the amylose-to-amylopectin ratio was significantly correlated with total free water and total water content(P≤0.05). Steaming induced differences in the material composition of C. kwangsiensis root tubers. Clustering of primary metabolites in the OPLS-DA model was distinct, while secondary metabolites were classified into 9 clusters using the K-means clustering algorithm. Differential terpenoid metabolites such as(-)-α-curcumene were significantly correlated with zerumbone, retinal, and all-trans-retinoic acid(P<0.05). Curcumenol was significantly correlated with isoalantolactone and ursolic acid(P<0.05), while all-trans-retinoic acid was significantly correlated with both zerumbone and retinal(P<0.05). Alpha-tocotrienol exhibited a significant correlation with retinal and all-trans-retinoic acid(P<0.05). Amylose was extremely significantly correlated with(-)-α-curcumene, curcumenol, zerumbone, retinal, all-trans-retinoic acid, and α-tocotrienol(P<0.05). Amylopectin was significantly correlated with zerumbone(P<0.05) and extremely significantly correlated with(-)-α-curcumene, curcumenol, zerumbone, retinal, all-trans-retinoic acid, and 9-cis-retinoic acid(P<0.01). The results provide scientific evidence for elucidating the mechanism of quality formation of steamed C. kwangsiensis root tubers as a medicinal material.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

BACKGROUND: Acupuncture therapy provides a complementary and alternative approach to treating major depressive disorder (MDD), but its efficacy and safety have still not been comprehensively assessed. Recently published systematic reviews remain confusing and inconclusive. OBJECTIVE: This systematic review evaluated the efficacy and safety of acupuncture therapy alone or combined with antidepressants for adult patients with mild and moderate MDD. SEARCH STRATEGY: Chinese Biomedical Literature Database, China National Knowledge Infrastructure Database, Wanfang Database, Chinese Science and Technology Journal Database, PubMed, Embase, and Cochrane Library were searched from their inceptions to March 2025. INCLUSION CRITERIA: Randomized controlled trials that compared acupuncture therapy with antidepressants, or acupuncture therapy plus antidepressants with acupuncture therapy or antidepressants for adult patients with mild and moderate MDD were included. DATA EXTRACTION AND ANALYSIS: Five reviewers independently extracted data from original literature using a standardized form, and the data were verified by two reviewers to ensure accuracy. Statistical meta-analyses, publication bias analyses, and subgroup analyses were performed by using Review Manager 5.3 software. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the certainty of the evidence. RESULTS: A total of 60 eligible studies including 4675 participants were included. Low-certainty evidence showed that compared with antidepressants, acupuncture therapy (standardized mean difference [SMD] = -0.57; 95% confidence interval [CI] = [-0.87, -0.27]; I² = 86%; P = 0.006) or acupuncture therapy plus antidepressants (SMD = -1.00; 95% CI = [-1.18, -0.81]; I² = 77%; P < 0.00001) may reduce the severity of depression at the end of treatment. Low-certainty evidence indicated that compared with acupuncture therapy alone, acupuncture therapy plus antidepressants slightly reduced the severity of depression at the end of treatment (SMD = -0.38; 95% CI = [-0.61, -0.14]; I² = 18%; P = 0.002). Similar results were also found for acupuncture's relief of insomnia. The reported adverse effects of acupuncture therapy were mild and transient. For most of the subgroup analyses, acupuncture type, scale type, and the course of treatment did not show a significant relative effect. CONCLUSION Acupuncture therapy may provide antidepressant effects and relieve insomnia with mild adverse effects for adult patients with mild and moderate MDD. But the certainty of evidence was very low. More high-quality, well designed, large-scale studies with long-term follow-up are needed in the future.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

BACKGROUND:Thromboelastography plays an important role in identifying the hypercoagulable state of blood and thrombosis in humans.Recent studies have shown a correlation between an increase in mean platelet volume and thrombosis.We can therefore ask whether the combined diagnosis of thromboelastography and mean platelet volume is a more accurate predictor of thrombosis. OBJECTIVE:To predict the status of blood and the occurrence of thrombosis after total knee arthroplasty by means of mean platelet volume combined with thromboelastography. METHODS:One hundred and twenty patients who underwent unilateral total knee arthroplasty between May 2015 and March 2022 were collected.Patients were divided into 60 patients in the thrombosis group and 60 patients in the control group based on ultrasound findings on postoperative day 7.Whole blood cell and thromboelastography were performed 1 day before,1 and 7 days after surgery,respectively.Multifactorial analysis was used to investigate independent predictors of thrombosis after total knee arthroplasty.The receiver operating characteristic curve and area under the curve were measured in the subjects. RESULTS AND CONCLUSION:Mean platelet volume correlated most strongly with maximum amplitude,followed by coagulation angle.Mean platelet volume and coagulation angle on postoperative day 1 were independent predictors of thrombosis.Mean platelet volume tended to rise and then fall in patients with thrombosis.The best critical value for mean platelet volume to predict thrombosis was 10.73 fL.The area under the receiver operating characteristic curve of subjects was 0.665(95%CI:0.568-0.762,P<0.05];whereas the area under the receiver operating characteristic curve for subjects using mean platelet volume combined with coagulation angle was 0.815(95%CI:0.750-0.879,P<0.05).In addition,the maximum amplitude,coagulation angle,coagulation index and mean platelet volume were significantly higher in the thrombosis group than in the control group postoperatively(P<0.05).The results suggest that the mean platelet volume can reflect the hypercoagulable state of blood after surgery,and the combination of mean platelet volume and coagulation angle on day 1 after total knee arthroplasty can improve the prediction of thrombosis.

BACKGROUND:Previous studies on the effects of valgus and varus angles of tibial component on short-term postoperative outcomes after mobile bearing unicompartmental knee arthroplasty have been reported in and outside China.However,there are few reports on the effect of the valgus and varus angles of tibial component on short-term postoperative outcomes after fixed bearing unicompartmental knee arthroplasty. OBJECTIVE:To investigate the effect of valgus and varus angles of tibial component on short-term clinical outcomes in patients with medial knee osteoarthritis undergoing fixed bearing unicompartmental knee arthroplasty. METHODS:120 patients(122 knees)who underwent fixed bearing unicompartmental knee arthroplasty for medial knee osteoarthritis in Department of Orthopedic Surgery,Affiliated Hospital of Xuzhou Medical University from August 2020 to January 2023 were selected as the study subjects.Two physicians measured the varus angle of femoral prosthesis,valgus and varus angles of tibial prosthesis,flexion and extension angles of femoral prosthesis,and posterior inclination angle of tibial prosthesis after unicompartmental knee arthroplasty based on postoperative X-ray.After excluding the influence of the other three angles,the measurement results of the tibial component varus angle were divided into three groups:<-2°,-2° to 2°,>2°,which were denoted as groups 1,2,and 3,respectively.The range of knee motion,the hospital for special surgery knee score,the American knee society score,and forgotten joint score were recorded and compared before and after the operation. RESULTS AND CONCLUSION:(1)A total of 120 patients(122 knees)were enrolled in this study.They were divided into three groups according to the size of the valgus and varus angles of the tibial prosthesis after operation:37 patients in the first group,60 patients in the second group,and 23 patients in the third group.There was no significant difference between the three groups in terms of baseline information such as age,gender,and side of surgery(P>0.05).(2)Patients were followed up for 3-30 months after arthroplasty.(3)The hospital for special surgery knee score of the second group was higher than that of the first group(P=0.015)and the third group(P=0.012).The American knee society score of the second group was significantly higher than that of the first group(P=0.014)and the third group(P<0.001).The forgotten joint score of the second group was higher than that of the first group(P=0.033)and the third group(P=0.016).(4)After fixed bearing unicompartmental knee arthroplasty,when the valgus angle of tibial prosthesis was-2° to 2°,which can achieve better short-term clinical results,the degree of prosthesis self-realization is higher.

BACKGROUND:After the treatment of femoral shaft fracture with the intramedullary nail,the third fracture open reduction indications are controversial.Some scholars believe that limited open reduction can achieve anatomical reduction,conducive to fracture healing;but some scholars believe that no open reduction of the third fracture still has a high fracture healing rate. OBJECTIVE:To investigate the effect of the circumference and displacement of the third fragment on fracture healing after intramedullary nailing of femoral shaft fractures with the third fragment. METHODS:A retrospective cohort study was conducted to analyze the clinical data of 142 patients suffered a femoral shaft fracture with a third fragment admitted to the Affiliated Lianyungang Hospital of Xuzhou Medical University from February 2016 to December 2021.The fracture were classified into three types according to the circumference of the third fracture with reference to the diaphyseal circumference at the fracture site:type 1 in 71 cases,type 2 in 52 cases,and type 3 in 19 cases.Referring to the diaphyseal diameter,the fractures were classified into three degrees according to the degree of the third fragment displacement:degree I in 95 cases,degree II in 31 cases,and degree III in 16 cases.All patients were treated with femoral interlocking intramedullary nails,and no intervention was performed for the displaced third fragment during the operation.Postoperative follow-up was performed to compare the fracture healing rate,healing time,and the modified Radiographic Union Scale for Tibia at month 9 after surgery in each group.The effect of third fracture fragment circumference and degree of displacement on fracture healing was assessed. RESULTS AND CONCLUSION:(1)All 142 patients were followed up for at least 12 months,with a mean of(14.7±4.1)months,and the overall healing rate was 73.4%.(2)When the third fragment was displaced by degree I,the healing rate,healing time,and modified Radiographic Union Scale for Tibia score at month 9 were not statistically significant among the three sub-groups of circumference classification.(3)When the third fragments were displaced by degree II or III,the healing rate and healing time were not statistically significant among the three subgroups of circumference classification;the modified Radiographic Union Scale for Tibia score at month 9 in the type 1 group was higher than that in the type 2 and 3 groups(P = 0.017).(4)Logistic regression analysis showed that a greater third fragment displacement and circumference were associated with lower fracture healing rates(P<0.05).(5)These findings indicate that in the treatment of femoral shaft fractures with third fragment by intramedullary nails,when the fracture fragment is displaced to degree I,the circumference size has little effect on fracture healing,and no intervention is required during surgery.When the third fragment is displaced to degree II or III and the circumference of which is type 1,a higher modified Radiographic Union Scale for Tibia score can still be obtained with no intervention of the third fragment.However,when the circumference is of type 2 or type 3,it significantly affects the fracture healing.Consequently,intraoperative intervention to reduce the distance of displacement of the fragment is required to lower the incidence of nonunion.The displacement of the third fracture fragments has a greater impact on fracture healing than their circumference.

Human genetic resources are an indispensable part of national natural science and technology resources,as well as an important strategic resource for safeguarding national security,public health,and social public interests.To promote the effective protection and rational utilization of human genetic resources,as well as improve and optimize the local human genetic resources management system in China,this paper summarized the current situation of administrative approval and supervision of national human genetic resources from 2004 to 2021 by sorting out the national human genetic resources management policies and regulations.Furthermore,the current situation and progress of local human genetic resources management in China were understood from three aspects,including development planning and programs of human genetic resources,administrative licensing and penalties,and the construction of management expert committees.The main problems of local human genetic resources management in China were discussed and analyzed,such as unclear supervision,difficulty in supervision and inspection,and capacity for services.Based on the causes of the problems and the local management work,specific countermeasures and suggestions were put forward from the perspective of clarifying the regulatory policies and procedures for human genetic resources,improving the supervision and inspection mechanisms,and improving the management and service capabilities.
