AIM: To compare the efficacy of intravitreal injection of ranibizumab(IVR)and intravitreal injection of conbercept(IVC)in children with retinopathy of prematurity(ROP).METHODS: Retrospective study. A total of 1 100 eyes with ROP treated with intravitreal anti-VEGF at our hospital from January 2015 to June 2023 were included. According to the different therapeutic drugs, the children were divided into two groups: IVR group and IVC group. According to the degree of ROP, the patients were divided into three groups: aggressive ROP(A-ROP), Zone Ⅰ type 1 ROP and Zone Ⅱ type 1 ROP. The reactivation and retreatment between the two groups were compared after propensity score matching(PSM)analysis, and they were followed-up for at least 3 mo after surgery.RESULTS: In Zone Ⅱ type 1 ROP, there was a statistically significant difference in the rates of reactivation and retreatment between the IVR and IVC groups(P<0.05); however, in A-ROP and Zone I type 1 ROP, there were no statistically significant differences in the rates of reactivation and retreatment between the two groups(P>0.05). The risk of reactivation and retreatment of Zone I type 1 ROP was higher than the Zone II type 1 ROP. Furthermore, the use of drugs and corrected gestational age of first treatment were influencing factors of lesion recurrence and retreatment.CONCLUSION: There is a significant difference in the initial cure effect between the two drugs in Zone II type 1 ROP, with the reactivation and retreatment rates of the IVC group being much lower than those of the IVR group.

BACKGROUND:In recent years,tranexamic acid has been extensively used to mitigate the substantial blood loss associated with total knee arthroplasty.However,the optimal method of topical application has not yet been established. OBJECTIVE:To evaluate the effectiveness and safety of intraoperative topical application of tranexamic acid combined with physical compression dressing in reducing perioperative blood loss in total knee arthroplasty. METHODS:A retrospective analysis was conducted on 90 patients who underwent total knee arthroplasty at the Honghui Hospital in Xi'an from January 2021 to December 2022.Based on the different topical use methods of tranexamic acid during surgery,patients were divided into three groups,with 30 cases in each group.In the compression dressing group,2 g of tranexamic acid was placed in the articular cavity,and after packing the wound with gauze and cotton pads,a bandage was used to compress the wound.In the periarticular injection group,2 g of tranexamic acid was injected into the surrounding tissue of the articular cavity.In the intra-articular injection group,2 g of tranexamic acid was injected into the articular cavity.The blood loss,operation time,coagulation indicators,inflammatory indicators,and postoperative complications of the three groups were statistically analyzed. RESULTS AND CONCLUSION:(1)In terms of total blood loss,hidden blood loss,and maximum hemoglobin drop,the periarticular injection group had the least amount,and there was no statistically significant difference between the compression dressing group and periarticular injection group(P>0.05).In terms of intraoperative blood loss,the compression dressing group had the least amount,and there were statistically significant differences compared with the periarticular injection group and intra-articular injection group(P<0.05).There was no statistically significant difference in operation time among the three groups(P>0.05).(2)There were no statistically significant differences in coagulation indicators(D-dimer and fibrinogen degradation products)and inflammation indicators(C-reactive protein and erythrocyte sedimentation rate)among the three groups preoperatively and on the first and third days after operation(P>0.05).(3)There was no statistically significant difference observed among the three groups in terms of slow blood flow in the affected limb,intramuscular venous thrombosis,soft tissue swelling,and incidence of wound complications(P>0.05).Additionally,no cases of deep vein thrombosis or pulmonary embolism were detected in any of the groups.(4)The topical application of tranexamic acid combined with compression dressing achieves the same effect as a periarticular injection in terms of simplicity of operation and reduced perioperative blood loss.This method also avoids the trauma caused by repeated punctures and does not increase the incidence of postoperative complications,making it a worthwhile option for clinical promotion.

Objective To analyze the type and incidence of abnormal chromosome karyotype in peripheral blood of infertile patients with different semen quality.Methods Selectet 292 infertility patients who came to our hospital from January 2018 to December 2021 for G-banding karyotyping and semen analysis.According to the semen analysis results,the patients were divided into abnormal semen quality group and normal control group.We made statistics and analysis on the abnormal karyotypes.Results In the group with abnormal semen quality,20 cases(18.87%)of abnormal karyotypes were found.In the normal control group,9 cases(4.84%)had abnormal karyotypes were found.The comparison of the abnormal rates of peripheral blood chromosome karyotypes between the two groups showed statistical significance(P<0.05).The detection rate of chromosomal abnormalities in patients with Azoospermia was 50%,and sex chromosome abnormalities were the main types of abnormalities in this group.Conclusion Karyotype analysis of infertile patients can effectively analyze the causes of infertility,and has important clinical significance for assisted reproduction and primary prevention of birth defects.

Objective:To understand the current status of gastroscopy in diagnosing gastric lesions in general population, and to recommend the optimal age for the first gastroscopy and intervals for repeated gastroscopy.Methods:The gastroscopy records of residents aged 18-80 years in Yinzhou District of Ningbo, Zhejiang Province, between April 2010 and December 2021 were analyzed retrospectively. The detections of gastric lesions across different years, age and genders were described. Goodness of fit tests were applied to compare the differences in detection rates of different lesions in first-time endoscopy in different age groups and different populations. Generalized additive models were used to fit the trend of age specific gastric lesion detection rate explore the optimal age for gastroscopy. The appropriate gastroscopy intervals were determined according to the progress of the gastric lesions detected in repeated gastroscopy.Results:A total of 237 751 participants with 344 398 gastroscopy records were included in analyses. A total of 5 597 cases of chronic atrophic gastritis (CAG), 9 796 cases of intestinal metaplasia (IM), 165 cases of low-grade intraepithelial neoplasia (LGIN), 52 cases of high-grade intraepithelial neoplasia (HGIN) and 435 cases of gastric cancer were detected by the first gastroscopy. The overall detection rate of gastric lesions increased significantly in age group 45-70 years, and remained stable after 70 years old, with LGIN and HGIN showing notable increases at 50 and 55 years old, respectively. Repeated gastroscopy detected CAG, IM, LGIN, and HGIN at a higher rate compared with the first gastroscopy. Normal/superficial gastritis progressed in 3-5 years, whereas CAG or more severe lesions progressed in 1-6 years.Conclusion:Gastroscopy is recommended for general population aged 45 years and above. Furthermore, gastroscopy can be performed every 3-5 years for individuals with normal endoscopy results and once a year for patients with CAG or more severe gastric lesions.

Objective To investigate serum levels of soluble apoptosis-related factor ligand(sFasL)and stromal cell derived factor 1(SDF-1)in patients with aplastic anemia(AA)and their correlation with immunosuppressive treatment.Methods Forty-three AA patients who received immunosuppressive therapy for half a year were selected as the observation group,and another 43 healthy subjects at the same period were selected as the control group.Patients in the observation group received immunosuppressive therapy and hematopoietic propoietic therapy,and patients were divided into the ineffective group and the effective group according to the efficacy.Clinical data of patients were collected,and serum levels of sFasL,SDF-1,tumor necrosis factor-α(TNF-α)and interleukin-8(IL-8)were detected by enzyme-linked immunosorbent assay.The correlation between serum sFasL and SDF-1 levels was analyzed.Multivariate Logistic regression analysis was conducted to analyze influencing factors of immunosuppressive treatment in AA patients.The predictive values of serum sFasL and SDF-1 on immunosuppressive treatment were analyzed by receiver operating characteristic(ROC)curve.Results Serum levels of sFasL and SDF-1 were higher in the observation group than those in the control group(P＜0.05).Serum levels of TNF-α,IL-8,sFasL and SDF-1 were higher in the ineffective group than those in the effective group(P＜0.05).Serum sFasL level was positively correlated with SDF-1 level in AA patients(r=0.534,P＜0.001).Increased serum sFasL and SDF-1 levels were independent risk factors for ineffective immunosuppressive therapy in AA patients(P＜0.05).The area under the curve(AUC)of serum sFasL and SDF-1 combined to predict the immunosuppressive treatment effect of AA patients was 0.973(95%CI:0.872-0.999),which was better than that of single diagnosis(P＜0.05),and its sensitivity and specificity were 94.44%and 96.00%,respectively.Conclusion Serum levels of sFasL and SDF-1 are significantly increased in patients with AA.The combined detection of sFasL and SDF-1 has high predictive value for the immunosuppressive treatment effect of AA.

Objective To predict the constitutive parameters of a superelastic model of plantar soft tissues based on random forest(RF)and backpropagation(BP)neural network algorithms to improve the efficiency and accuracy of the method for obtaining constitutive parameters.Methods First,a finite element model for a spherical indentation experiment of plantar soft tissues was established,and the spherical indentation experiment process was simulated to obtain a dataset of nonlinear displacement and indentation force,divided into training and testing sets.The established RF and BP neural network(BPNN)models were trained separately.The constitutive parameters of plantar soft tissues were predicted using experimental data.Finally,the mean square error(MSE)and coefficient of determination(R2)were introduced to evaluate the accuracy of the model prediction,and the effectiveness of the model was verified by comparison with the experimental curves.Results Combining the RF and BPNN models with finite element simulation was an effective and accurate method for determining the superelastic constitutive parameters of plantar soft tissues.After training,the MSE of the RF model reached 1.370 2×10-3,and R2 was 0.982 9,whereas the MSE of the BPNN model reached 4.858 1×10-5,and R2 was 0.999 3.The inverse-determined constitutive parameters of the plantar soft tissues suitable for simulation were obtained.The calculated response curves for the two predicted sets of constitutive parameters were in good agreement with the experimental curves.Conclusions The prediction accuracy for the superelastic constitutive parameters of plantar soft tissues based on an artificial intelligence algorithm model is high,and the relevant research results can be applied to study other mechanical properties of plantar soft tissues.This study provides a new method for obtaining the constitutive parameters of plantar soft tissues and helps to quickly diagnose clinical problems,such as plantar soft tissue lesions.

AIM:To investigate the molecular mechanisms of KG-1 cell proliferation by profiling its responses to various protein kinase inhibitors.METHODS:CCK-8 assay,real time quantitative PCR(qRT-PCR)and Western-blot were used to detect the effect of various protein kinase inhibitors on KG-1 cell proliferation,the expression levels of mRNA and phosphorylation level of signaling pro-teins in the FGFR1 downstream pathways.RE-SULTS:NVP-BGJ398 and PD173074 effectively in-hibited the proliferation of KG-1 cells,indicative of a crucial role of FGFR downstream signaling.After treatment with FGFR inhibitors,the levels of p-FG-FR1OP2-FGFR1 and p-STAT5 decreased significantly(P<0.001),p-AKT decreased slightly(P<0.05),with-out affecting the p-ERK level(P>0.05).CONCLU-SION:FGFR1OP2-FGFR1 mainly acts on the down-stream STAT5 signaling pathway to promote cell proliferation.Comprehensive protein kinase inhibi-tion analysis is a reliable and direct approach to identify functional drivers of cancer cell prolifera-tion.

Depression is a mental disorder with high morbidity, disability and relapse rates. Ginkgo biloba extract (GBE), a traditional Chinese medicine, has a long history of clinical application in the treatment of cerebral and mental disorders, but the key mechanism remains incompletely understood. Here we showed that GEB exerted anti-depressant effect in mice through regulating gut microbial metabolism. GBE protected against unpredictable mild stress (UMS)-induced despair, anxiety-like and social avoidance behavior in mice without sufficient brain distribution. Fecal microbiome transplantation transmitted, while antibiotic cocktail abrogated the protective effect of GBE. Spatiotemporal bacterial profiling and metabolomics assay revealed a potential involvement of Parasutterella excrementihominis and the bile acid metabolite ursodeoxycholic acid (UDCA) in the effect of GBE. UDCA administration induced depression-like behavior in mice. Together, these findings suggest that GBE acts on gut microbiome-modulated bile acid metabolism to alleviate stress-induced depression.
