AIM: To compare the diagnostic efficiency of binocular uncorrected distance visual acuity(UCDVA), pre-cycloplegia refraction spherical equivalent(PR-SE), axial length(AL)difference, and their different combinations in the screening of anisometropia in children and adolescents, and to evaluate the practical value of different indicator combinations in simplifying the screening process when taking cycloplegic retinoscopy results as the gold standard for diagnosing anisometropia.METHODS: This was a retrospective study. A total of 500 consecutive cases of children and adolescents aged 6-18 years with known refractive status were included. Taking cycloplegic retinoscopy results as the gold standard for anisometropia diagnosis, the binocular UCDVA, PR-SE, and AL difference were incorporated into ROC curve analysis to assess the diagnostic efficacy of each indicator. Furthermore, predictive models were constructed and reliability analysis was performed.RESULTS: The average age of the included cases was 10.75±2.24 years, including 239 males and 261 females. The AUC of the interocular PR-SE difference(0.972, 95%CI: 0.960-0.984)was significantly higher than that of other indicators. The Youden index was the largest when the bincular UCDVA difference was 0.25, the PR-SE difference was 0.743, and the AL difference was 0.31. When the interocular PR-SE difference used 0.743 and 1.00 D as screening cutoffs, the former had a higher AUC(AUC=0.924, 95%CI: 0.895-0.953). Comparison of different constructed predictive models showed that when the binocular PR-SE difference was ≥0.743 D, the negative predictive value reached 98.89%, making it suitable for initial screening. The combination of UCDVA+PR-SE+AL had the highest specificity and positive predictive value, while the PR-SE+AL combination had the highest consistency rate.CONCLUSION: The binocular PR-SE difference is the best choice for single-indicator screening. Combining UCDVA and AL can increase the specificity to 98.00% and the positive predictive value to 88.24%. The PR-SE+AL combination can achieve the highest consistency rate.

Objective:To explore the efficacy and safety of tislelizumab combined with zanubrutinib in the treatment of refractory diffuse large B-cell lymphoma (DLBCL).Methods:A prospective observational study was conducted. A total of 10 patients with refractory DLBCL admitted to Beijing Chaoyang District Third Ring Cancer Hospital, a specialist medical consortium of Cancer Hospital Chinese Academy of Medical Sciences from November 2020 to February 2023 were prospectively collected. All the 10 refractory DLBCL patients at least received first-line systemic therapy containing rituximab; and they were given tislelizumab 200 mg, intravenous infusion, on day 1 and zanubrutinib 160 mg, orally, twice a day, day 1-day 21, with 21 days as 1 cycle; 6 patients received second-line therapy and 4 patients received ≥ third-line therapy. Subsequent regimens were added with rituximab (375 mg/m 2, intravenous infusion on day 1). The primary endpoint will be reached 12 months after enrollment if there was no disease progression or other events that were scheduled to withdraw from the study. The therapeutic efficacy was summarized at the end of the follow-up in March 2023. Kaplan-Meier method was used to make survival analysis and the adverse reactions were summed up. Results:There were 6 males and 4 females, all at stage Ⅲ-Ⅳ; and age [ M ( Q1, Q3)] was 55 years (50 years, 69 years). All 10 patients completed 90 cycles of treatment with tislelizumab and zanubrutinib, with the cycle number of 8 cycles (2 cycles, 24 cycles). The follow-up time was 19 months (11 months, 28 months); 4 cases achieved complete remission, 3 cases achieved partial remission and 1 case had the stable disease. The progression-free survival was 8.5 months (1.3 months, 27.0 months); the median remission duration time and median overall survival time were not reached. Treatment-related adverse reactions included 2 cases of neutropenia, 1 case of anemia, and 1 case of elevated alanine aminotransferase and aspartate aminotransferase, all of which were grade 1-2. Conclusions:Tislelizumab combined with zanubrutinib has good clinical efficacy and safety in the treatment of refractory DLBCL.

Objective To observe the effect of ultrasound-guided iliopsoas plane block(IPB)on the quality of postoperative recovery in patients undergoing hip arthroplasty.Methods Sixty patients who underwent hip arthroplasty were selected,37 males and 23 females,aged 40-79 years,BMI 18-30 kg/m2,ASA physical status Ⅰ-Ⅲ.The patients were divided into two groups by random number table method:the iliopsoas plane block group(group IPB)and the femoral nerve block(FNB)group(group FNB),30 pa-tients in each group.Before anesthesia induction,IPB was performed with 0.5%ropivacaine 10 ml and lat-eral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group IPB.And FNB was performed with 0.5%ropivacaine 10 ml and lateral femoral cutaneous nerve block was performed with 0.5%ropivacaine 5 ml in group FNB.The dosages of propofol,remifentanil,and cis-atracurium during operation were recorded.The quality of recovery-15(QoR-15)scale was evaluated preoperatively and postoperatively 1 day,2 and 3 days.The max VAS(VASmax)pain score and manual muscle test(MMT)score of quadri-ceps muscle were recorded 12,24,and 48 hours after surgery.The time of getting out of bed for the first time,opioid dosage,and patient satisfaction were recorded.The incidence of nerve injury,vascular injury,puncture site infection,and local anesthetic poisoning were recorded.The postoperative complications of diz-ziness,nausea and vomiting,deep vein thromboses,and elirium were also recorded.Results There was no significant difference in the dosage of propofol,remifentanil,and cis-atracurium between the two groups.Compared with group FNB,the QoR-15 scale score in group IPB was significantly higher 1 day,2 and 3 days after operation(P＜0.05).Compared with group FNB,the MMT scores of quadriceps muscle was sig-nificantly higher in group IPB 12 and 24 hours after surgery(P＜0.05),and the first time of getting out of bed was shortened in group IPB(P＜0.05).However,there were no significant differences in the VASmax pain score,MMT score of quadriceps muscle 48 hours after surgery,opioid dosage,and patient satisfaction between the two groups.No nerve block related complications were found in both groups.There were no sig-nificant differences in postoperative complications between the two groups.Conclusion The iliopsoas plane block can improve the quality of postoperative recovery and accelerate the recovery of patients with hip re-placement,and the effect is better than that of femoral nerve block.

AIM: To evaluate the value of the ratio of axial length to corneal radius of curvature(AL/CR)in the diagnosis of myopia in children and adolescents.METHODS: The refraction and ocular biometric parameters of 2 182 cases of children and adolescents(4 364 eyes)who initially visited the optometry clinic of the Second People's Hospital of Beihai from January 2022 to December 2023 were collected and analyzed.RESULTS: The receiver operating characteristic curve(ROC curve)showed that AL/CR had a higher area under the curve(AUC=0.925, 95%CI: 0.917-0.933)in diagnosing myopia. When AL/CR was 3.053, the Youden index was the largest. As the threshold of AL/CR decreased, the sensitivity of myopia diagnosis increased, while the specificity decreased. Compared with screening myopia, the sensitivity of AL/CR=3.053 in diagnosing myopia was low, but the specificity was high, especially in the cases of hyperopia and pre-myopia.CONCLUSION: The accuracy of AL/CR in diagnosing myopia is superior to that of axial length and average corneal curvature, with higher specificity. As the threshold of AL/CR decreases, the sensitivity of diagnosing myopia increases, but the specificity decreases. In cases of hyperopia and pre-myopia, the specificity of AL/CR in diagnosing myopia is higher than that of screening myopia.

Objective To explore the selection strategy of diagnostic and therapeutic regimens and assess the efficacy for postoperative infection following internal fixation of patellar fractures. Methods A retrospective analysis was conducted on the clinical data of 12 patients with postoperative infection after internal fixation of patellar fractures. Results A total of 6 patients underwent complete removal of the internal fixation devices during debridement and were subsequently fixed with knee braces, while the other 6 had their original internal fixation devices removed and replaced with Kirschner wire fixation. Three patients developed septic arthritis and underwent knee arthroscopic lavage treatment. All 12 patients underwent bacterial culture and metagenomic next-generation sequencing (mNGS) testing, and the key pathogenic bacteria were successfully identified by mNGS. All wounds achieved primary healing within 2 weeks after closure. At the final follow-up, all patients exhibited good fracture healing, with Böstman patellar fracture function scores ranging from 24 to 29 (mean score of 26.58), and the outcomes were evaluated as excellent in 7 cases and good in 5, resulting in an excellent and good rate of 100.0%. Conclusion For patients with early and delayed postoperative infections following internal fixation of patellar fractures, removal of the internal fixation devices can help reduce the risk of infection recurrence. For patients with concurrent septic arthritis, early diagnosis and timely implementation of arthroscopic joint debridement and irrigation and drainage are crucial.

Objective To analyze and compare the auxiliary value and significance of γ-interferon release assay (IGRA) in the diagnosis of tuberculosis. Methods A retrospective analysis was conducted to collect the test results of 462 suspected tuberculosis patients who underwent IGRA detection in the outpatient department of Tianjin Tuberculosis Control Center from January 2020 to December 2021. According to the diagnostic results, they were divided into a tuberculosis group of 229 cases (203 cases of pulmonary tuberculosis and 26 cases of extrapulmonary tuberculosis) and a non-tuberculosis group of 233 cases. The auxiliary diagnostic value of IGRA for tuberculosis was analyzed and compared with two methods of Mycobacterium tuberculosis culture and Xpert MTB/RIF. Results The positive rates of IGRA, Mycobacterium tuberculosis culture, and Xpert MTB/RIF in TB patients were 76.42%, 29.26% and 40.62%, respectively, compared with the non-TB group (38.20%, 0.00%, 0.00%), with statistically significant differences (P<0.001). The sensitivity, specificity, positive predictive value, and negative predictive value of IGRA alone in the detection of tuberculosis were 76.42%, 61.80%, 69.29%, and 72.73% respectively, those of Mycobacterium tuberculosis culture were 29.26%, 98.28%, 94.37%, and 63.43%, and those of Xpert MTB/RIF were 40.60%, 100%, 100%, and 63.14%. The positive rates of IGRA were 76.85% and 73.08% in patients with pulmonary tuberculosis and extrapulmonary tuberculosis, respectively, with no statistical significance (P>0.05). The positive rates of IGRA in bacterial positive patients and non-tuberculosis patients were 79.34% and 38.20%, respectively, with statistical significance (χ2=54.526, P<0.001). The positive rates of IGRA in patients with and without tuberculosis were 73.15% and 38.20%, respectively, with significant difference (χ2=36.456, P<0.001). Conclusions IGRA has a relatively high sensitivity in the diagnosis of tuberculosis and also has certain advantages in the screening of extrapulmonary tuberculosis and mycobacterium-negative It provides important reference basis for the clinical diagnosis of tuberculosis.

Objective:To evaluate the diagnostic value of rapid on-site evaluation (ROSE) performed by endoscopists for solid pancreatic lesions requiring tissue for immunohistochemistry (IHC) staining with different approach of endoscopic ultrasound-guided tissue acquisition (EUS-TA).Methods:After screening 1 573 cases who underwent EUS-TA operation at the Endoscopy Center of Peking Union Medical College Hospital between August 2018 and October 2022, a total of 65 cases of solid pancreatic lesions whose diagnosis rely on IHC staining was collected and summarized with clinical data of each case. Among 65 cases, there were 46 cases of pancreatic neuroendocrine tumors (PNETs), 13 cases of pancreatic solid pseudo-papillary tumors (SPTs), and 6 cases of lymphomas and mesenchymal. Patients were categorized into ROSE group (36 cases) and non-ROSE group (29 cases) according to the presence or absence of endoscopists performed ROSE during EUS-TA operation. They were further divided into subgroups of FNA-ROSE (26 cases), FNB-ROSE (10 cases), FNA-non-ROSE (24 cases) and FNB-non-ROSE (5 cases) according to the type of EUS-TA. Diagnostic accuracy and IHC success rate were compared between different groups and subgroups. Binomial logistic multifactorial regression analysis was used to evaluate the influence of ROSE and EUS-TA type on diagnostic accuracy and IHC success rate.Results:There were no statistically significant differences between ROSE group and non-ROSE group in terms of age, gender, bilirubin level, CA19-9 level, lesion site, lesion size, composition ratio of diagnosis, and surgical rate. The differences in mean size of lesions, needle gauge, location of puncturation, and number of needle pass between subgroups were not statistically significant. The diagnostic accuracy was 88.9% in ROSE group and 79.3% in non-ROSE group, and the difference between the two groups was statistically significant ( P=0.023). The diagnostic accuracy of FNA-ROSE group was higher than that of FNA-non-ROSE group (88.5% vs 75.0%), but the difference was not statistically significant ( P>0.100). The differences in diagnostic accuracy and success rate of IHC between FNB-ROSE group and FNB-non-ROSE group were not statistically significant. Binomial logistic multifactorial regression analysis did not reveal any independent influences on diagnostic accuracy. Conclusions:ROSE performed by endoscopists improved diagnostic accuracy of EUS-TA in solid pancreatic lesions requiring IHC staining, and therefore is potentially valuable for improving the diagnostic efficiency of EUS-TA for such diseases.
