BACKGROUND: Hypertension is a serious chronic disease that can significantly lead to various cardiovascular diseases, affecting vital organs such as the heart, brain, and kidneys. Our goal is to predict the risk of new onset hypertension using machine learning algorithms and identify the characteristics of patients with new onset hypertension. METHODS: We analyzed data from the 2011 China Health and Nutrition Survey cohort of individuals who were not hypertensive at baseline and had follow-up results available for prediction by 2015. We tested and evaluated the performance of four traditional machine learning algorithms commonly used in epidemiological studies: Logistic Regression, Support Vector Machine, XGBoost, LightGBM, and two deep learning algorithms: TabNet and AMFormer model. We modeled using 16 and 29 features, respectively. SHAP values were applied to select key features associated with new onset hypertension. RESULTS: A total of 4,982 participants were included in the analysis, of whom 1,017 developed hypertension during the 4-year follow-up. Among the 16-feature models, Logistic Regression had the highest AUC of 0.784(0.775∼0.806). In the 29-feature prediction models, AMFormer performed the best with an AUC of 0.802(0.795∼0.820), and also scored the highest in MCC (0.417, 95%CI: 0.400∼0.434) and F1 (0.503, 95%CI: 0.484∼0.505) metrics, demonstrating superior overall performance compared to the other models. Additionally, key features selected based on the AMFormer, such as age, province, waist circumference, urban or rural location, education level, employment status, weight, WHR, and BMI, played significant roles. CONCLUSION We used the AMFormer model for the first time in predicting new onset hypertension and achieved the best results among the six algorithms tested. Key features associated with new onset hypertension can be determined through this algorithm. The practice of machine learning algorithms can further enhance the predictive efficacy of diseases and identify risk factors for diseases.

Hypercalciuria, as a common clinical feature of kidney stones, is a common feature of hereditary diseases such as idiopathic hypercalciuria, autosomal dominant hypocalcaemia, Bartter's syndrome, Dent disease, hereditary hypophosphataemic rickets with hypercalciuria, infantile hypercalcaemia, familial hypomagnesemia with hypercalciuria and nephrocalcinosis, hereditary distal renal tubular acidosis, However, the clinical phenotypes and genotypes of these hypercalciuric kidney stones have their own characteristics. We summarized the results of recent genetic studies on hypercalciuria to promote clinical screening, diagnosis and reasonable treatment.

Objective:To study the expression characteristics of myocardial strain index after the abnormal origin of the left coronary artery of the pulmonary artery in children was repaired.Methods:The data of 30 children (study group) with abnormal origin of pulmonary artery left coronary artery repair from August 2017 to August 2021 were analyzed. In addition, healthy children during the same period were selected as the control group, and the study group was compared before and after treatment and the control group. Circumferential and radial peak myocardial strain index, post-contraction strain index.Results:The longitudinal, circumferential, and radial overall peak strain indexes of the study group before and after treatment were significantly lower than those of the control group, and the longitudinal, circumferential, and radial overall peak strain indexes of the study group after treatment were significantly higher than those before treatment ( P<0.05); The longitudinal, circumferential, and radial peak strain indexes of the study group before treatment were significantly lower than those of the control group. After treatment in the study group, the middle section of the longitudinal inferior wall, the middle section of the anterior wall, the basal section of the anterior wall, the apex, and the circumferential direction were significantly lower The peak strain index of the basal segment of the inferior wall and the middle segment of the inferior wall was significantly lower than that of the control group; and the longitudinal, circumferential, and radial peak strain indexes of the study group after treatment were significantly higher than those before treatment ( P<0.05); the study group children before treatment Longitudinal, circumferential, and radial PSI indexes were significantly lower than those of the control group. After treatment, the study group was treated in the longitudinal inferior wall, septal apical segment, circumferential inferior wall basal segment, inferior wall middle segment, and radial PSI anterior wall basal segment, apex. The part was significantly higher than that of the control group; and the longitudinal, circumferential, and radial PSI of the study group after treatment were significantly lower than before treatment ( P<0.05). Conclusion:After ALCAPA repair, the overall and regional strain and overall synchronization are improved, indicating that the resting myocardium has recovered, but the strain of certain segments supplied by the abnormal left coronary artery fails to normalize after ALCAPA repair. Persistent myocardial injury is consistent, which can provide some guidance for the prognosis assessment of children with ALCAPA.

【Objective】 To investigate whether the psychological counseling nursing could alleviate psychological stress and reduce the incidence of adverse events in patients receiving advanced autologous apheresis (AAA) treatment. 【Methods】 A total of 253 patients who underwent AAA treatment in our department from September 2019 to February 2020 were studied and randomly divided into the observation group (n=127) and the control group (n=126). Other than the routine nursing, the patients in the observation group also received psychological counseling nursing. The scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to compare the psychological stress state and the incidence of adverse events between two groups, and the nursing satisfaction was evaluated by NSNS scores. 【Results】 The SAS and SDS scores in the observation group( after receiving counseling nursing as the psychological intervention) were 30.03±5.06 and 33.59±4.49, respectively, significantly lower than those in the control group (43.55±3.68 and 42.18±4.22, respectively) (P<0.05). The incidences of adverse events (convulsions not included) in the observation group and the control group were 11.8%(15/127) vs 26.2%(33/126) (palpitation and shortness of breath), 6.3%(8/127) vs 16.7%(21/126) (sweating), 8.7%(11/127) vs 23.8%(30/126) (dizziness and numbness in mouth), and 5.5%(7/127) vs 19.8%(30/126) (nausea), respectively (P<0.05). The total nursing satisfaction rate of the observation group was 98.4% (125/127), which was significantly higher than that of the control group (92.9%, 117/126) (P<0.05). 【Conclusion】 The psychological counseling nursing can effectively relieve the psychological stress of patients receiving AAA treatment and reduce the incidence of adverse events.

The secondary damage after traumatic brain injury (TBI) involves a variety of pathological processes, and the inflammatory response in the nervous system is an important factor which affects nerve repair and regeneration. As the innate immune cell in the nervous system, microglia (MG) plays an important role in the entire neuroinflammatory environment by regulating the activation state of MG and changing the inflammatory response in the direction of promoting nerve repair and regeneration, which has great potential in treatment of TBI. This article reviews the inflammatory response of the nervous system after TBI and the reactivity of MG, as well as their significance in nerve repair and regeneration.

Optic nerve gliomas (ONGs) are one type of optic pathway gliomas (OPGs), enjoying low incidence; they accounts for only 1% of intracranial tumors in children. They can either occur sporadically or complicate with neurofibromatosis type 1 (NF1). ONGs have unique clinical features, and the courses of diseases are variable and difficult to predict. Accurate diagnosis and reasonable treatment are controversial. This review focuses on the clinical features, diagnosis, and treatment of ONGs, in order to provide references for the treatment and follow-up research of ONGs.

The primary fourth ventricle meningiomas (FVMs) are rare fourth intraventricular tumors. Meningiomas account for approximately 13%-20% of all intracranial tumors; 0.5%-3% of meningiomas locate in the ventricle, whereas only 5% of meningiomas locate in the ventricle occur in the fourth ventricle. To date, the report about the FVMs is less than 80 cases all over the world, and most of the literatures about this disease are case reports. The clinical manifestations, imaging features, intraoperative findings and prognoses are lack of comprehensive understanding. In this paper, based on the FVMs case reports and research progress in recent years, we aim to summarize the clinical characteristics and treatment of FVMs to provide a beneficial reference for the diagnoses and treatments of FVMs.

As a kind of neuroectodermal tumor, ependymoma usually occurs in the spine in adults. However, 90% of children's ependymomas are intracranially located, and two thirds of them are located in the posterior fossa. The most commonly used clinical treatment for posterior fossa ependymomas is surgery combined with postoperative adjuvant therapy, but the high recurrence rate and poor prognosis suggest that it is urgent to explore more targeted and efficient treatment methods. In recent years, molecular biology technology has developed rapidly, the molecular biological characteristics of posterior fossa ependymomas are partially elucidated, and the molecular typing has been preliminarily determined and many potential therapeutic targets have been proposed. This review focuses on the role of histone H3 lysine 27 trimethylation in posterior fossa ependymoma and its potential therapeutic targets to provide references for treatments and follow-up researches of this disease.

Objective: To evaluate the short-term and long-term efficacy of endoscopic submucosal dissection (ESD) in the treatment of early low rectal cancer and precancerous lesions. Methods: Inclusion criteria: (1) Distance from the lower margin of tumor to the anal was ≤ 5 cm. (2) Early low rectal cancers were any size rectal epithelial tumors with infiltration depth limited to the mucosa and submucosa, which were diagnosed by postoperative pathology as high-grade intraepithelial neoplasia or adenocarcinoma of the rectum with infiltration depth of intramucosal or submucosal cancer (M or SM stage). (3) Precancerous lesions included adenoma and low-grade intraepithelial neoplasia of the rectum. (4) Patients received ESD treatment. Patients with tumor invasion depth over submucosa by pathology were excluded. From January 2008 to January 2018, 63 patients meeting the above criteria in Peking University First Hospital were enrolled in this descriptive cohort study. The disease characteristics, clinical manifestations, pathological types, treatment time, hospitalization time, en bloc resection rate (resection of the whole lesion), complete resection rate (both the horizontal and vertical incision margins were negative), postoperative complications and follow-up results were analyzed. Cummulative survival rate was calculated by Kaplan-Meier. Results: The diameter of the lesion was (29.0±23.4) mm and the distance from the lesion to the anus was (2.7±1.8) cm. The median operation time was 45.0 (range, 10.0 to 360.0) minutes, the median hospitalization time was 3.0 (range, 2.0 to 12.0) days, en bloc resection rate was 100%, complete resection rate was 96.8% (61/63), and 1 case (1.6%) had postoperative bleeding. The follow-up rate was 87.3% (55/63) and the median follow-up time was 57.9 (range, 15.6 to 121.1) months. No local recurrence was found during the follow-up period and the 5-year survival rate was 100%. Conclusion Short- and long-term efficacy of ESD are quite good in the treatment of patients with early low rectal cancer and precancerous lesions.
