OBJECTIVE To systematically evaluate the efficacy and safety of tislelizumab in the treatment of advanced non- small cell lung cancer （NSCLC）. METHODS Computerized searches were conducted in PubMed， Embase， the Cochrane Library， CNKI， Wanfang and other Chinese and English databases to collect randomized controlled trials （RCTs） on tislelizumab for advanced NSCLC. The search period was from the establishment of the databases to December 2024. After strictly screening the literature， extracting data and conducting quality evaluations in accordance with the inclusion and exclusion criteria， a meta-analysis was performed using RevMan 5.3 and Stata 16.0 software. RESULTS A total of 18 RCTs involving 2 337 patients were included， with 1 283 in the experimental group and 1 054 in the control group. The meta-analysis results showed that the objective response rate [RR＝1.61， 95%CI （1.48， 1.75）， P＜0.000 01]， disease control rate [RR＝1.21， 95%CI （1.13， 1.29）， P＜0.000 01]， progression free survival [HR＝0.55， 95%CI （0.45， 0.66）， P＜0.000 01]， and overall survival [HR＝0.78， 95%CI（0.62， 0.97）， P＝0.03] were significantly better in the experimental group than in the control group. There was no statistically significant difference in the incidence of adverse reactions between the two groups [RR＝1.00， 95%CI （0.73， 1.37）， P＝1.00]； among the common adverse reactions， only the incidence of liver function impairment was significantly higher in the experimental group than in the control group [RR＝1.30， 95%CI （1.10， 1.54）， P＜0.01]. CONCLUSIONS Tislelizumab in combination with chemotherapy or targeted drugs significantly improves the efficacy in patients with advanced NSCLC without increasing the risk of adverse reactions overall. However， liver function should be closely monitored during treatment.

Objective To explore the operative indication operation time and post-operative care for infants with large ventricular septal defects (VSD).Methods Eighty-eight infants who suffered from large VSD were selected,male 53 cases,female 35 cases,aged from 3 to 18 months[average (7.5-±2.9) months],weight from 5 to 13 kg [average (7.9 ± 1.9) kg].All patients underwent VSD repair and other accompanied anomaly corrections under cardiopulmonary bypass.Fifty-eight cases were operated through right atrium,14 cases through pulmonary artery and 16 cases through right ventricle.Patch repairs were done in all patients,78 cases given bovine pericardium patches,10 cases given self pericardium patches treated by Glutaral.Patients were sent to the intensive care unit after surgery,vasoactive drugs were used as a routine method.Antibotics were selected based on their sputum cultures postoperatively.Nutritional support was given in the earlier stage.Results There were no hospital death,average hospitalization days were (15.2 ± 5.9) days (from 11 to 32 days).The main complication were pneumonia (5 cases),bad coalesce of incision (4 cases),atelectasis (3 cases),minimal residual shunt of VSD (3 cases).All patients were discharged from hospital,76 cases were followed up from 1 to 12 months,2 cases had residual shunt of VSD,the residual shunt of the other case disappeared;76 patients had no clinical symptom,28 patients body weight returned to normal after 6 months of operation.There was no other complication and death.Conclusion Early surgical treatment for infants with large VSD is a safe and effective way with a better prognosis.

Objective To study the characteristic findings on magnetic resonance imaging (MRI) in children with cerebral palsy (CP) induced by chronic kernicterus.Methods The MR imagings in 13 CP cases induced by chronic kernicterus were retrospectively studied, which were compared with 6 healthy and age-matched controls. 13 cases were finally diagnosed as dyskinetic cerebral palsy (athetoid subtype).Results In 13 cases, all showed symmetric high signals in the the globus pallidus on T2-weighted imaging. There were not apparent abnormality on T1-weighted imaging.Conclusion The bilateral high intensity signals in the globus pallidus on T2-weighted imaging are the characteristic findings on MRI in CP children induced by chronic kernicterus. Paying attention to the globus pallidus on MRI may be useful in determining the type of cerebral palsy.
