BACKGROUND: To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study. METHODS: This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well. RESULTS: The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P  <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n  = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β  <0, P  <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed. CONCLUSIONS: The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR2200055247).

Cognitive dysfunction often occurs in Alzheimer's disease, Parkinson's disease, cerebrovascular disease, or other neurodegenerative diseases, and can significantly impact the life quality of patients and create serious social, psychological, and economic burdens for individuals and their families. Numerous studies have confirmed that exercise can slow the decline in cognitive function through multiple pathways, in which fibronectin type III domain-containing protein 5 (FNDC5) plays an important role. However, the current research on the modulation of FNDC5 by exercise and its ability to improve hippocampal cognitive function lacks a systematic and comprehensive understanding. Therefore, this review focuses on the latest research progress regarding the role of exercise-induced FNDC5 in cognitive function, systematically reviews the positive effects of FNDC5 on cognitive function impairment caused by various factors, and clarifies the specific mechanisms by which exercise-induced FNDC5 improves cognitive function by inhibiting neuroinflammation and improving hippocampal neurogenesis and hippocampal synaptic plasticity. Based on the existing literature, we also identify the areas that require further research in this field. Overall, this review provides a theoretical basis for exercise-based prevention and improvement of cognitive function impairment.

Pancreatic cystic neoplasm (PCN) is characterized by cystic degeneration with a low incidence. With the development of imaging technology and the popularization of screening, the detection rate of this disease has been increasing in recent years, especially in the elderly population. Due to the multiple subtypes of PCN, difficult differential diagnosis, and the potential risk of malig-nant transformation, the formulation of reasonable diagnosis and treatment strategy is the key to treat PCN. Although many clinical guidelines have been released, the diagnosis and treatment strategies of PCN are still controversial. Elderly patients are generally weak, some with serious comorbidities, and have poor tolerance to surgery. In the process of diagnosis and treatment, clinicians need to pay special attention, carefully evaluate and weigh the advantages and disadvantages, so as to make the best plan for treatment. Based on the current guidelines and clinical experience, the authors summarize the diagnosis, surgical indications, and the whole-course management strategies of elderly patients with PCN, in order to provide suggestions for the diagnosis and treatment of this disease.

Objective:To investigate Helicobactor pylori (H. pylori) infection status and interfamilial transmission pattern in Zhengzhou area. Methods:A cross-sectional study was conducted from September 2020 to march 2021, among 731 individual from 266 families randomly selected from 9 communities of Zhengzhou area. H. pylori infection status was determined by serum antibody tests, and 13C-urea breath test was performed in the previously eradicated population to clarify the current infection status. The individual and familial infection rate, infection status for couples and children and adolescent were analyzed. Results:Among 731 individuals from 266 families, 397 of them were H. pylori positive. The individual infection rate was 54.31% (397/731); among infected individuals 77.83% (307/397) were infected with type Ⅰ strain, 22.67% (90/397) were infected by type Ⅱ strain. Annual household income ( χ2=0.419, 0.410, 0.213, all P>0.05), smoking history (χ 2=0.071, P>0.05), drinking history ( χ2=0.071, P>0.05), dining place ( χ2=0.009, P>0.05), gastrointestinal symptoms ( χ2=0.047, P>0.05), family history of gastric disease ( χ2=0.069, P>0.05), and history of gastric cancer ( χ2=0.004, P>0.05) had no significant differences between H. pylori-positive and -negative groups, but the infection rate in individuals with higher education level was lower ( χ2=4.449, P<0.05). The infection rate was significantly higher in≥18 age groups compared with<18 age groups ( χ2=6.531, 23.362, 20.671, 24.244, 37.948, 14.597 and 5.170, all P<0.05). The familial H. pylori infection rate was 87.59% (233/266), and in 61 families all member were infected (26.18%, 61/233). The positive rate was 23.08% (6/26) in 50 families with children under 18 years when both parents were infected. Among 231 coupled families, both couples were infected in 78 families (33.76%), one couple was infected in 113 families (48.92%), and both couples were not infected in 40 (17.32%). With the increase of marriage time, the infection rate of both spouses increased significantly ( χ2=7.775, 12.662, 15.487, all P<0.05). Conclusions:The distribution of H. pylori infection presents a family cluster pattern, and intrafamilial infection is an important transmission rout of H. pylori. The type I strain of H. pylori is the dominate strain in this area.

Objective:To systematically review the risk prediction models for diabetic retinopathy in patients with type 2 diabetes mellitus (T2DM) .Methods:Literature regarding the risk prediction models for diabetic retinopathy in T2DM were searched from CINAHL, PubMed, Web of Science, Cochrane Library, Embase, Wanfang, CNKI, VIP, and China Biology Medicine disc, with the search timeframe extending to October 1, 2022. Two researchers independently selected literature and extracted data, and the bias risk and applicability of the included literature were analyzed using the PROBAST tool for assessing risk of bias in prediction model studies.Results:A total of 14 articles were included. Age, duration of diabetes, glycated hemoglobin, proteinuria, blood pressure, and serum creatinine levels were the main predictive factors for diabetic retinopathy in T2DM; the Area Under the Receiver Operating Characteristic (ROC) curve of the predictive models ranged from 0.683 to 0.984, with calibration conducted in 6 models; 4 studies used external validation, while the rest used internal validation. All studies demonstrated good applicability, but all presented bias risk.Conclusions:The risk prediction models for diabetic retinopathy in T2DM demonstrate good predictive performance. However, high bias risk due to methodological flaws (such as improper handling of missing data, inappropriate methods for variable selection, lack of blinding, etc.) indicates they cannot be directly applied to clinical practice. Future work should either conduct extensive validation on existing models or undertake large-scale, diverse prospective studies to develop predictive models with superior performance and user-friendly application.

OBJECTIVE: To explore the molecular basis for a pedigree affected with coagulation factor V (FV) deficiency. METHODS: Clinical data of the patient and his family members was analyzed. Targeted capture and next-generation sequencing (NGS) and Sanger sequencing were carried out to detect potential variant of the FV gene. RESULTS: The patient presented with jaundice and prolonged prothrombin time (PT) and activated partial thromboplastic time (APTT). V factor activity measured only 0.1% of the normal level, though the patient had no sign of bleeding. A paternal heterozygous variant c.653T>C (p.F218S) and a maternal heterozygous variant c.3642_3643del (p.P1215Rfs*175) were identified in the FV gene of the patient. His elder brother was a heterozygous carrier of the c.653T>C (p.F218S) variant. c.653T>C(p.F218S) was a known pathogenic variant, while the c.3642_3643del (p.P1215Rfs*175) variant was unreported previously. CONCLUSION Mutations of the FV gene probably underlie the hereditary coagulation factor V deficiency in this patient. NGS combined with Sanger sequencing has detected potential variant with efficiency and provided a reliable basis for clinical and prenatal diagnosis for this family.
