AIM: To evaluate whether Wnt pathway-related genes previously implicated in high myopia(HM)could serve as candidate genes for HM in the Chinese Han population, and to identify risk loci associated with HM susceptibility.METHODS: A case-control association analysis was conducted, involving 530 HM patients(HM group)and 1 087 healthy controls. The test efficacy was estimated using Quanto software. Peripheral blood DNA was extracted using the magnetic bead method, and seven candidate single nucleotide polymorphisms(SNPs)were genotyped using the Sequenom MassARRAY system, including HIVEP3 rs17365632, rs35134694, rs11210537, CTNNB1 rs13072632, CAMK2N1 rs10753502, TCF4 rs41396445 and Wnt7B rs73175083. Differences in allele and genotype frequencies between the HM and healthy control groups were compared under different inheritance models. Haplotype analysis was performed using SHEsis plus.RESULTS: All 7 SNPs had a genotyping detection rate exceeding 90%, and were in Hardy-Weinberg equilibrium(P>0.05). The test efficacy of the sample size was above 90.13%, indicating that the samples were representative of the population. In the HM group, the A allele frequency of HIVEP3 rs11210537 was significantly reduced(Pc=0.003, OR=0.889). Conversely, the G allele frequency was significantly elevated(Pc=0.003, OR=1.176). In an additive genetic model(AA vs GG), the AA genotype frequency was significantly lower than the GG genotype frequency(Pc=0.003, OR=0.583). Additionally, the frequency of the CCA haplotype of rs17365632, rs35134694, and rs11210537 in HIVEP3 was decreased in the HM group compared to the control group(Pc=0.008, OR=0.791).CONCLUSION: The SNP locus rs11210537 in the HIVEP3 gene is associated with genetic susceptibility to HM in the Chinese Han population, with the G allele identified as risk genetic markers. The CCA haplotype of rs17365632, rs35134694, and rs11210537 in the HIVEP3 gene represents a protection haplotype for HM.

Objective: To apply network analysis for exploring the relationship of maltreatment experiences and peer relationships with school bullying among middle school students, so as to provide empirical evidences for the development of targeted intervention programs. Methods: From March to April 2024, a total of 2 119 middle school students aged 12-18 in Shantou City were selected through stratified cluster random sampling. Self administered questionnaire was used to collect data on bullying experiences, maltreatment, and peer relationships. The Glasso network model was employed to estimate network structure. Results: The strongest edge in the network of maltreatment experiences, peer relationships and school bullying was the connecting line connecting peer acceptance and peer terrorized low self esteem (edge weight=0.59) among middle school students. The network faked fraudulent victimization was the most central node in the whole network (strength=7.98). The bridge symptoms of the network were sexual abuse, property bullying of others, relational bullying victimization, and verbal bullying of others, with the strongest bridge node being sexual abuse (bridge strength=1.07). In the accuracy estimation of centrality indices, closeness centrality demonstrated the highest accuracy, followed by strength and betweenness, with coefficient of stability of 0.60, 0.44 and 0.21, respectively. The stability of the network was good. Conclusion Peer acceptance has the strongest correlation with peer fear and inferiority, and is closely related to emotional abuse and emotional neglect.

Objective:To determine the risk factors for permanent nerve damage (PND) after aortic arch surgery in patients with acute type A aortic dissection (AAAD).Methods:This was a retrospective case-control study. The medical records from patients of both sexes with AAAD, aged > 18 yr, of American Society of Anesthesiologists Physical Status classification IV, who underwent aortic arch surgery in the Second Hospital of Hebei Medical University from December 2018 to December 2023, were collected. The patients were divided into non-PND group and PND group according to whether PND occurred after operation. The preoperative data of patients were collected, including age, gender, body mass index; comorbidities (hypertension, coronary heart disease, diabetes mellitus), history of smoking, history of stroke, and history of cardiovascular surgeries; syncope at onset, preoperative low SpO 2, preoperative low systolic blood pressure, and preoperative low diastolic blood pressure. The intraoperative data included surgical procedure (total aortic arch replacement or half aortic arch replacement), selective antegrade cerebral perfusion during operation, cardiopulmonary bypass (CPB) time, aortic cross-clamp time, post-parallel time, moderate hypothermia circulatory arrest time, nasopharyngeal temperature and rectal temperature during circulatory arrest, and BIS value during circulatory arrest; blood pressure during cardiopulmonary bypass and after restoration of heart beat; the incidence of dysfunction after recovery of heart beat and difficulty in hemostasis after termination of CPB. The aforementioned indicators were analyzed for difference, and the indicators with P<0.05 were included in the multivariate logistic regression analysis. Results:A total of 292 patients were ultimately included, among which 73 developed postoperative PND, resulting in an incidence of 25.0%. The results of multivariate logistic regression analysis showed that age ≥62 yr ( OR=3.783, 95% confidence interval [ CI] 1.513-10.346, P=0.006), preoperative hypertension ( OR=2.230, 95% CI 1.118-4.715, P=0.028), syncope at onset ( OR=3.001, 95% CI 1.343-6.710, P=0.007), BIS value > 14 during circulatory arrest ( OR=2.439, 95% CI 1.249-4.755, P=0.009) and difficult hemostasis after termination of CPB ( OR=3.465, 95% CI 1.758-6.882, P<0.001) were risk factors for PND after surgery. Conclusions:Age ≥ 62 yr, history of hypertension, syncope at onset, BIS value greater than 14 during circulatory arrest and difficulty in hemostasis after termination of CPB are risk factors for PND after aortic arch surgery in patients with AAAD.

This article reports two cases of proteinuria caused by anti-vascular endothelial growth factor (VEGF) drugs in the treatment of liver cancer and ovarian cancer, respectively. Hypertension, massive albuminuria and renal insufficiency occurred in the patient with liver cancer during the use of toripalimab/camrelizumab combined with lenvatinib and regorafenib, and urinary protein was 4.02 g/24 h. The patient with ovarian cancer developed hypertension, proteinuria and 1.13 g/24 h urinary protein during the use of bevacizumab. Renal biopsy showed thrombotic microangiopathy in the glomeruli of both patients. Anti-VEGF drugs-associated glomerular microangiopathy was considered. The patient with liver cancer had no improvement after halving the dose of lenvatinib, and the effect was not good after treatment with low-dose corticosteroids combined with renin-angiotensin-aldosterone system inhibitors. After stopping anti-VEGF drugs, the proteinuria in both patients turned negative.

Targeted radiation therapy using radionuclides is a favored approach for treating tumors.This procedure involves the delivery of drugs to the lesion site via carriers or interventional methods,followed by the emission of radiation energy that selectively irradiates the lesion tissue.This approach minimizes damage to normal tissue and achieves the desired therapeutic effect.Factors such as the type of therapeutic radionuclide,radiation energy,physical half-life,method of preparation,and toxicity determine their clinical application.In this paper,the characteristics and clinical application of therapeutic radionuclides were reviewed to providing reference for the clinical application of targeted therapeutic radionuclides.
