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.

Objective:To investigate the application value of donor liver autologous portal venous blood rinse in orthotopic liver transplantation (OLT).Methods:The retrospective cohort study was conducted. The clinicopathological data of 35 pairs of donors and recipients who underwent OLT in the First Affiliated Hospital of University of Science and Technology of China from May 2018 to June 2019 were collected. Of the 35 donors, there were 31 males and 4 females, aged (48±9)years. Of the 35 recipients, there were 25 males and 10 females, aged (47±9)years. Of the 35 recipients, 16 recipients undergoing donor liver autologous portal venous blood rinse were allocated into the portal vein group, and 19 recipients undergoing donor liver albumin water rinse were allocated into the albumin group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data of skewed distribution were represented as M(range). Count data were descried as absolute numbers, and comparison between groups was analyzed using the Fisher exact probability. Results:(1) Surgical situations. The anhepatic phase time and arterial blood Ca 2+ concentration within 5 minutes after reperfusion of the recipients were (52±12)minutes and (0.99±0.10)mmol/L in the portal vein group, versus (64±12)minutes and (1.05±0.07)mmol/L in the albumin group, showing significant differences in the above indicators between the two groups ( t=2.94, 2.22, P<0.05). The mean arterial pressure, arterial blood K +concentration and arterial blood pH within 5 minutes after reperfusion of the recipients were (70±24)mmHg (1 mmHg=0.133 kPa), (4.7±1.3)mmol/L and 7.27±0.06 in the portal vein group, versus (71±28)mmHg, (4.6±1.1)mmol/L and 7.30±0.07 in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.14, 0.30, 1.22, P>0.05). (2) Post-operative situations. Cases with post-reperfusion syndrome (PRS), cases with severe PRS of cardiac arrest, cases with primary graft nonfunction of the recipients were 6, 0, 2 in the portal vein group, versus 8, 1, 1 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). Total bilirubin on postoperative day 7 of the recipients was (90±52)μmol/L in the portal vein group, versus (166±112)μmol/L in the albumin group, showing a significant difference between the two groups ( t=2.66, P<0.05). International normalized ratio on postoperative day 7, the highest alanine aminotransferase and aspartate aminotransferase within 7 days after operation of the recipients were 2.1±2.0, (1 952±2 813)IU/L and (3 944±6 673)IU/L in the portal vein group, versus 1.8±0.6, (1 023±1 014) IU/L and (2 005±2 910)IU/L in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.66, 1.23, 1.08, P>0.05). Recipients with hepatic artery complication and biliary complication were 1 and 2 in the portal vein group, versus 0 and 4 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). There were 3 cases and 2 cases died during the perioperative period in the portal vein group and the albumin group, respectively. (3) Follow-up. Of the 35 recipients, 30 recipients were followed up for 534(range, 28?776)days after operation. During the follow-up, there were 3 patients with postoperative complications in the portal vein group including 2 cases died and 1 case recovered after sympto-matic treatment. There were 5 patients with postoperative complications in the albumin group including 1 case died and 4 cases recovered after symptomatic treatment. Up to the follow-up date, 11 patients in the portal vein group and 16 patients in the albumin group were in good condition. Conclusion:Rinse of the donor liver with autologous portal venous blood during liver transplantation can shorten the time of anhepatic phase, without increasing the occurrence of post-reperfusion syndrome, ischemia re-perfusion injury and biliary tract complications.

Objective To evaluate the role of multi-disciplinary team (MDT) in improving the diagnosis and treatment of human herpes virus-6B (HHV-6B) encephalitis after liver transplantation. Methods MDT consultation was delivered for one rare case of HHV-6B encephalitis after liver transplantation to establish an effective individualized treatment regime. Results On the 16 d after liver transplantation, the patient developed headache, and suddenly presented with unresponsiveness, unconsciousness, coma complicated with involuntary limb twitching on the 18 d. Blood ammonia level was increased. Brain CT scan showed cerebral ischemic changes. Electroencephalography prompted the epileptic seizure. After MDT consultation, the possibility of nervous system infection after liver transplantation was considered, and medication therapy was given to control the epileptic seizure. Cerebrospinal fluid examination via lumbar puncture hinted increased intracranial pressure. Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) of the cerebrospinal fluid demonstrated that the patient was tested positive for HHV-6B nucleic acid, which confirmed the diagnosis of HHV-6B encephalitis. The immunosuppressant regime was adjusted, intravenous ganciclovir was given for antiviral treatment, and active interventions were delivered to prevent and treat relevant complications. Epileptic seizure disappeared after 4 d, and neurological symptoms were significantly alleviated after 2 weeks. After 4-week antiviral treatment, the patient was tested negative for virology testing, and the neurological function was restored to normal. Conclusions HHV-6B encephalitis rarely occurs after adult liver transplantation, which is primarily associated with the virus reactivation after use of immunosuppressant. MDT pattern may be employed to deepen the understanding of the patient's condition, formulate more effective individualized treatment regime, and enhance the clinical efficacy and safety.

Purpose: This study aimed to investigate the clinicopathologic features and mutational landscape of patients with hepatitis B virus (HBV)–related advanced hepatocellular carcinomas (HCC) undergoing transcatheter arterial chemoembolization (TACE). Materials and Methods: From January 2017 to December 2018, 38 patients newly diagnosed with HBV-related advanced HCC were enrolled in the final analysis. Their pathological tissues and corresponding blood samples before TACE treatment were collected for whole-exome sequencing. Response to TACE was evaluated at 1-3 months after two consecutive use of TACE. Predictive factors were analyzed by univariate and multivariate analyses in a bivariate Logistic regression model. Enrichment of related pathways of all driver genes were acquired using the gene set enrichment analysis (GSEA). Results: Among 38 patients, 23 (60.5%) exhibited TACE failure/refractoriness. Patients with TACE failure/refractoriness showed higher frequency of TP53 mutation than their counterparts (p=0.020). Univariate and multivariate analyses showed that only vascular invasion and TP53 mutation were significantly correlated with TACE failure/refractoriness in HBV-related advanced HCC. Of the 16 patients without vascular invasion, eight (50.0%) had TP53 mutations, and TP53 mutation was associated with TACE failure/refractoriness (p=0.041). Moreover, GSEA showed that mitogen-activated protein kinase and apoptosis pathways induced by TP53 mutation were possibly associated with TACE failure/refractoriness. Conclusion Our study suggested that TP53 mutation was independently related with TACE efficacy, which may work via mitogen-activated protein kinase and apoptosis pathways. These findings may provide evidence to help distinguish patients who will particularly benefit from TACE from those who require more personalized therapeutic regimens and rigorous surveillance in HBV-related advanced HCC.

Objective To assess the prospect of integrated biphasic silk fibroin scaffold made by annulus fibrosus-nu?cleus pulposus tissue engineering in application as integrated intervertebral disc(IVD). Methods An integrated annulus fi brosus-nucleus pulposus(AF-NP)biphasic scaffold was made by silk fi broin using two different uncomplicated methods which were paraffin spheres-leaching method(outer AF phase)and phase separation method(inner NP phase). The scaf?fold was investigated by general observation, stereomicroscope and scanning electron microscopy(SEM). Its pore size, poros?ity, and compressive elastic modulus were determined. AF and NP cells were isolated from rabbit IVD and seeded into the corresponding phase of the scaffold respectively. The cell-scaffold complex was cultured for 48 hours. The biocompatibility of the scaffold was evaluated by SEM, live/dead staining while CCK-8 assay was used to assess cell proliferation. Results Stereomicroscope and SEM showed that AF phase and NP phase integrated perfectly without cross-linking. Both phases pos?sessed highly interconnected porous structure [pore size of AF and NP phase were(220.0±23.1)μm and(90.0±17.8)μm, re?spectively] and highly porosity(AF and NP phase were respectively 91%and 93%). In addition, this silk biphasic scaffold had impressive mechanical properties(150.7 ± 6.8)kPa. SEM revealed that disc cells attached to regions of pore walls, dis?tributed uniformly and secreted extracellular matrix. Live/Dead staining and cell count kit-8(CCK-8)analysis showed that the silk composite scaffold was non-cytotoxic to disc cells. Conclusion This silk biphasic AF-NP scaffold has satisfied pore size, porosity, biomechanical properties and biocompatibility, so it is ideal candidate for IVD tissue engineering.
