Phacoemulsification with intraocular lens implantation(Phaco+lOL)has become the main treatment for cataracts due to small incision and fast recovery. Phacoemulsification can damage the conjunctiva, cornea and other ocular surface tissues, causing local inflammation, which in turn leads to eye dryness and discomfort after surgery. According to studies, patients who suffer from phacoemulsification most experience dry eye syndrome within 24 h, which gradually worsens and reaches its peak in the following 1 wk, seriously affecting their quality of life. The review aims to comprehensively investigate the effects of preoperative patient physical conditions and local ocular status, intraoperative maneuvers and postoperative treatments on postoperative dry eye, with the expectation of formulating scientific and effective preventive measures for potential dry eye patients after phacoemulsification, and providing a theoretical basis for postoperative dry eye treatment.

Objective:To evaluate the safety and efficacy of using small and ultra-small sized grafts for in situ auxiliary liver transplantation in the treatment of portal hypertension.Methods:A prospective single-arm cohort study was conducted. Patients who underwent liver transplantation at Beijing Friendship Hospital from December 2014 to July 2025 were included. Intraoperative portal vein pressure was routinely monitored, with the target regulation for portal vein blood flow set at<15 mmHg (1 mmHg=0.133 kPa) and follow-up continued until September 2025. The primary endpoints were the patient's status and graft survival. The secondary endpoints were small-for-size syndrome and perioperative complications. The small-for-size syndrome was graded according to the 2023 International Liver Transplantation Society consensus statement.Results:A total of 33 cases were enrolled. Among them, 22 had ultra-small size grafts, 11 had small-size grafts, 28 had living donor grafts, and five had split grafts. The graft-to-recipient weight ratio in living donor liver transplantation was 0.31%～0.79%, while in split liver transplantation it was 0.45%～1.02%. Intraoperative portal vein pressure of ≥15 mmHg was observed in 11 cases, who underwent portal vein blood flow adjustment via splenic artery ligation (2 cases), partial splenectomy (8 cases), and/or restrictive portocaval shunting (1 case), after which all patients achieved the target portal vein pressure. All cases completed at least one month of follow-up, with 28 cases following for more than one year, and the median follow-up period was 36.5 months. Early-stage postoperative small-for-size syndrome occurred in eight cases (24.2%, 8/33), all classified as grade A, with improvements following supportive treatment. Severe complications (Clavien-Dindo≥Ⅲ) occurred in three cases (9.1%, 3/33). The one-year survival rate was 92.9% (26/28). The overall survival rate at the end of follow-up was 90.9% (30/33). No patients experienced graft loss or death due to small-for-size syndrome. Graft tissue tested negative for hepatitis B core antibody and covalently closed circular DNA, and hepatitis B surface antigen seroconversion was achieved following second-stage residual liver resection and under a combined strategy of potent nucleos(t)ide analogs and hepatitis B immunoglobulin in ten cases of hepatitis B-related disease.Conclusions:With standardized portal vein blood flow monitoring and individualized portal vein blood flow adjustment, in situ auxiliary liver transplantation can safely and effectively use small and even ultra-small sized grafts, thereby significantly expanding graft sources and ensuring donor and recipient safety. These findings warrant further validation and promotion in multicenter controlled studies.

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 evaluate the clinical outcome of neurosurgical robot-assisted stereotactic puncture and drainage for brain abscess.Methods A retrospective analysis was conducted on the clinical data of 53 patients with brain abscess admitted to our hospital from January 2018 to December 2024.Among them,29 cases underwent craniotomy for abscess resection(craniotomy group),while 24 cases received neurosurgical robot-assisted stereotactic puncture and drainage(robot-assisted group).The operation time,intraoperative blood loss,decompressive craniectomy rate,proportion of postoperative antibiotic regimen adjustment,postoperative hospital stay,incidence of postoperative complications,mortality rate and Glasgow outcome scale(GOS)scores 6 months after surgery of patients were compared between the two groups.Results Compared with the craniotomy group,the robot-assisted group demonstrated significantly shorter operation time,less intraoperative blood loss,and lower incidence of postoperative complication,the differences were all statistically significant(P<0.05).However,there were no statistically significant differences in terms of decompressive craniectomy rate,postoperative hospital stay,mortality rate,GOS score,or proportion of the postoperative antibiotic regimen adjustment between the two groups(P>0.05).Conclusion As a precise and minimally invasive surgical method,neurosurgical robot-assisted stereotactic puncture and drainage for patients with brain abscess can effectively improve the operational efficiency,shorten the operation time,reduce intraoperative injury,and lower the risk of postoperative complications.It has high clinical application value and potential for widespread adoption.
