OBJECTIVE: To investigate the effectiveness of knee arthroscopy with wire anchor nailing composite double pulley technique in the treatment of anterior cruciate ligament (ACL) tibial avulsion fracture involving the anterior root of the lateral meniscus (LM). METHODS: Clinical data of 35 patients with ACL tibial avulsion fracture involving the anterior root of the LM admitted between January 2019 and September 2023 and met the selection criteria were retrospectively analysed. There were 20 males and 15 females; ages ranged from 10 to 57 years, with a mean of 29 years. The time from injury to surgery ranged from 3 to 20 days, with a mean of 9.6 days. Meyers-McKeever classification included 5 cases of type Ⅱ, 12 cases of type Ⅲ, and 18 cases of type Ⅳ. Preoperative anterior knee instability Lachman test and anterior drawer test were positive. The anterior root of the LM as well as the avulsion fracture block were fixed using suture anchor nails compounded with double pulley technique under arthroscopy. Postoperative X-ray films were performed to assess fracture healing; knee stability was assessed using the anterior drawer test and Lachman test, anterior laxity of the knee was measured by KT-2000, and knee function was assessed using the Lysholm score and the International Knee Documentation Committee (IKDC) score; at last follow-up, the recovery of the meniscus was assessed using the McMurry test and knee hyperextension test. RESULTS: All the patients were successfully operated, the operation time ranged from 56 to 78 minutes,with an average of 67.6 minutes, and there was no nerve or blood vessel injury during operation. Thirty-five cases were followed up 12-18 months with an average of 15.1 months. During the follow-up, there was no infection, knee stiffness, loosening of internal fixation, fracture displacement, or re-fracture. The fractures all healed, with a clinical healing time of 8-15 weeks, averaging 10.9 weeks. At last follow-up, 4 patients had weakly positive anterior drawer test and Lachman test, and the rest were negative; McMurry test and knee hyperextension test were negative; no patient complained of knee extension pain or straightening obstacles, and all the patients resumed their normal life or sports and labour; 16 patients with unclosed epiphyses did not have any epiphyseal injuries or growth disorders. Lysholm score, IKDC score, and KT-2000 anterior knee laxity at last follow-up significantly improved when compared with preoperative ones ( P<0.05). CONCLUSION The treatment of ACL tibial avulsion fracture involving the anterior root of the LM with suture anchor composite double pulley technique can effectively fix the anterior root of the LM while fixing the avulsion fracture block, and better restore the function and stability of the knee joint.

Hepatocellular carcinoma （HCC） is a common malignancy in China， and molecular-targeted drugs and immune checkpoint inhibitors for the treatment of advanced HCC are currently a research hotspot； however， there are large individual differences in the treatment outcome of advanced HCC. In order to further screen for the population with benefits from such treatment， predict treatment outcome， and improve disease prognosis， this article summarizes the studies on predicting the efficacy of targeted therapy/immunotherapy for HCC， so as to provide a reference for developing individualized treatment regimens for patients with advanced HCC.

Objective To investigate the efficacy and safety of programmed death receptor-1 (PD-1) inhibitor combined with transarterial chemoembolization (TACE) and anti-angiogenic drug tyrosine kinase inhibitor (TKI) versus TACE combined with TKI in the treatment of advanced hepatocellular carcinoma (HCC) and related influencing factors for prognosis. Methods An analysis was performed for all patients who received TACE+TKI+PD-1 inhibitor and some patients who received TACE+TKI in The First Affiliated Hospital of Air Force Medical University from June 2018 to July 2021. Related clinical data were collected, and propensity score matching (PSM) was used to balance the baseline characteristics between groups. The chi-square test was used for comparison of categorical data between two groups; the Wilcoxon rank-sum test was used for comparison of the number of TACE procedures between two groups; the Kaplan-Meier method was used to analyze overall survival (OS), and univariate and multivariate Cox regression models were used to analyze the influencing factors for prognosis. Results A total of 181 patients with advanced HCC were screened out, among whom 50 patients were treated with TACE+TKI+PD-1 inhibitor; after PSM, 40 patients treated with TACE+TKI+PD-1 inhibitor were enrolled as observation group and 40 patients treated with TACE+TKI were enrolled as control group. At the end of follow-up, the median follow-up time was 28.6 (95% confidence interval [ CI ]: 22.1-35.1) months, and the median OS was 15.9 (95% CI : 7.5-24.2) months in the observation group and 11.2 (95% CI : 5.0-17.5) months in the control group. The Cox regression analysis showed that the application of PD-1 inhibitor (hazard ratio [ HR ]=0.42, 95% CI : 0.23-0.80, P =0.008), the number of TACE procedures ( HR =0.67, 95% CI : 0.46-0.99, P =0.043), Child-Pugh class ( HR =2.40, 95% CI : 1.15-5.00, P =0.019), and vascular invasion ( HR =3.42, 95% CI : 1.11-9.42, P =0.031) were independent influencing factors for prognosis. The incidence rate of grade > 2 adverse events was 40% for both the observation group and the control group, and there was no significant difference between the two groups ( P =0.818). Conclusion Compared with TACE+TKI, TACE+TKI+PD-1 inhibitor can significantly prolong the OS of patients in advanced HCC, with relatively controllable adverse events.
