OBJECTIVES: Intracranial aneurysm (IA) has an insidious onset, and once ruptured, it carries high rates of mortality and disability. Cardiometabolic factors may be associated with the formation and rupture of IA. This study aims to summarize the application of Mendelian randomization (MR) methods in research on cardiometabolic factors and IA, providing insights for further elucidation of IA etiology and pathogenesis. METHODS: Literature about MR-based IA studies published up to February 21, 2024, was retrieved from PubMed, Embase, Web of Science, CNKI, and Wanfang. Two researchers independently performed literature screening, data extraction, and quality assessment. A narrative synthesis approach was used to conduct a qualitative systematic review of the included studies. RESULTS: A total of 11 MR-based studies on IA published between 2017 to 2024 were included, of which 4 were rated as high quality. These studies investigated the associations between blood pressure, blood lipids, blood glucose, obesity-related indicators, and inflammatory cytokines with IA and its subtypes, though issues of duplication were noted. Four MR studies based on the same European population but using different instrumental variable selection criteria, as well as another MR study in a different European cohort, consistently identified blood pressure as a risk factor for IA and its subtypes. Findings for blood lipids, blood glucose, obesity-related indicators, and inflammatory cytokines were inconsistent across MR studies. CONCLUSIONS Blood pressure appears to increase the risk of IA and its subtypes. Associations between other cardiometabolic factors and IA/subtypes require further in-depth investigation. Given the inherent limitations of MR studies, causal inferences should be made cautiously in combination with other lines of evidence.

The theory of " Sui Qi Suo De" originates from Zhang Zhongjing's Jin Gui Yao Lue and has been further developed by later generations of practitioners, offering significant guidance for clinical practice. Myelodysplastic syndromes (MDS) are common malignant disorders of the hematopoietic system, characterized by high heterogeneity and progressive mutational changes. In Traditional Chinese Medicine (TCM), MDS falls under the category of "marrow toxin exhaustion". This article applies the theory of " Sui Qi Suo De" in TCM to analyze the pathophysiological changes during different stages of MDS. Specifically, it explores the precursor stage (focusing on health maintenance and prevention before illness, addressing the " Suo De" of "gradual decline of vital qi"), the low-risk stage (strengthening the spleen and kidneys, clearing toxic pathogens, addressing the " Suo De" of "weakened vital qi invaded by pathogens"), and the medium-to-high-risk stage (detoxifying and reinforcing the body, harmonizing physical and mental health, addressing the " Suo De" of "dominant pathogens and declining vital qi"). The goal is to provide new directions and theoretical insights for the TCM treatment of MDS.

The method of decocting and taking medicine can directly influence the efficacy of the Chinese herbal medicine,and is the key to enhancing efficacy and reducing toxicity.As the originator of classic books for traditional Chinese medicine(TCM)prescriptions,Treatise on Exogenous Febrile Diseases has recorded various specific methods of decocting and taking medicine in details.This paper summarized and sorted out various methods of decocting the same Chinese herbal medicine,re-decocting method with the removal of dregs(for concentrating medicinal solution),method of decocting pills,dosage of medicine,time for taking medicine,and notices and healthcare after medication recorded in Treatise on Exogenous Febrile Diseases.Moreover,the dialectical view in the method of decocting medicine recorded in Treatise on Exogenous Febrile Diseases.was explored.The special method of decocting and taking medicine in Treatise on Exogenous Febrile Diseases included the TCM dialectical view of using the same Chinese herbal medicine for the treatment of different diseases,consideration of both Chinese herbal medicine and syndromes,drastic purgatives for chasing long-term efficacy.The method of taking medicine contained the TCM dialectical view of modification of the medicine dosage according to syndrome differentiation,adapting to the general trend,and suspension after medicine starting an effect.It is believed that the method of decocting and taking medicine for the prescriptions in Treatise on Exogenous Febrile Diseases is established according to syndrome differentiation,and the utilization of various methods of decocting and taking medicine as well as notices and healthcare after medication in accordance with the characteristics of diseases and syndromes ensures the prescriptions meeting the pathogenesis,and then enhance the clinical efficacy.

Ring finger protein 213(RNF213)was first identified as a susceptible gene for Moyamoya disease,and also found to be associated with various vascular related diseases such as intracranial artery occlusion/stenosis,ischaemic stroke,intracranial aneurysm,cerebral arteriovenous malformation,etc.This article systematically reviewed the literature of RNF213,providing an overview of the association and possible mechanisms between RNF213 variation and related diseases,in order to provide reference for the prevention,diagnosis,and treatment of related diseases.

The application of pesticides(mostly insecticides and fungicides)during the tea-planting process will undoubtedly increase the dietary risk associated with drinking tea.Thus,it is necessary to ascertain whether pesticide residues in tea products exceed the maximum residue limits.However,the complex matrices present in tea samples comprise a major challenge in the analytical detection of pesticide residues.In this study,nine types of lateral flow immunochromatographic strips(LFICSs)were developed to detect the pesticides of interest(fenpropathrin,chlorpyrifos,imidacloprid,thiamethoxam,acet-amiprid,carbendazim,chlorothalonil,pyraclostrobin,and iprodione).To reduce the interference of tea substrates on the assay sensitivity,the pretreatment conditions for tea samples,including the extraction solvent,extraction time,and purification agent,were optimized for the simultaneous detection of these pesticides.The entire testing procedure(including pretreatment and detection)could be completed within 30 min.The detected results of authentic tea samples were confirmed by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS),which suggest that the LFICS coupled with sample rapid pretreatment can be used for on-site rapid screening of the target pesticide in tea products prior to their market release.

Objective:To investigate the clinical and genetic characteristics of developmental and epileptic encephalopathy (DEE) caused by SLC1A2 gene mutations. Methods:The clinical manifestations, auxiliary examination results, and genetic testing results of a patient with DEE caused by SLC1A2 gene mutations who was treated at Epilepsy Center, Children's Hospital Affiliated to Shandong University on February 6, 2021 were summarized. Cases of SLC1A2 gene mutations were searched using keywords " SLC1A2" and "developmental and epileptic encephalopathy" in CNKI, Wanfang, and PubMed databases, retrieving literature published from the establishment of these databases to September 2024. Bioinformatics analysis was performed; the clinical and genetic characteristics of DEE caused by SLC1A2 gene mutations were summarized. Results:The main manifestations of the patient were rhythmic shaking of the right upper limb or focal motor seizures of bilateral upper limbs, or focal spasm of right upper limb (elevation for once). Ictal electroencephalogram showed 2-3 Hz polymorphic slow waves in the left central area, parietal area and central midline area, affecting the opposite side, or spike rhythm with decreased frequency in the right frontal area, central area and midline area, or polymorphic slow waves in the left central area and central midline area. Whole-exome sequencing indicated a heterozygous de novo mutation in the SLC1A2 gene: c.254T>G/p.Leu85Arg. A total of 7 patients with DEE caused by SLC1A2 gene mutations were retrieved from 5 related literature. All 8 patients (including the patient in our hospital) presented with epileptic seizure, developmental delay, and abnormal EEG; all of them were sporadic cases with de novo heterozygous missense mutations of SLC1A2 gene. Bioinformatics analysis showed that the 4 amino acid residues Gly82, Leu85, Pro289, and Pro333 in the 8 patients were located in the intolerance region of SLC1A2 gene encoding glutamate transporter protein 2 (EAAT2). The 5 amino acid mutations (Leu85Arg, Leu85Pro, Gly82Arg, Pro333Ser, Pro289Arg) in the 8 patients all led to significant changes in number and binding of hydrogen bonds between amino acid residues in EAAT2; except for Gly82Arg mutation, the other 4 mutations could obviously reduce the structural stability of EAAT2. Conclusion:De novo heterozygous missense mutations in SLC1A2 gene can lead to DEE, characterized by developmental delay, EEG abnormalities, and epileptic seizure; these mutations are typically located in critical regions of EAAT2, potentially resulting in reduced protein structural stability.

OBJECTIVES: Stroke has become the leading cause of death and disability among adults in China. This study aims to analyze the disease burden based on gender and age and the risk factors for stroke subtypes in China 2019, and to provide reference for targeted stroke prevention and control. METHODS: Based on 2019 data of the Global Burden of Disease (GBD), the gender and age in patients with different stroke subtypes (ischemic stroke, intracranial hemorrhage, subarachnoid hemorrhage) in China 2019 was described by using disability-adjusted life years (DALY), and attributable burden of related risk factors was analyzed. RESULTS: In 2019, the burden of intracranial hemorrhage was the heaviest one in China, resulting in 22.210 6 million person years of DALY, following by ischemic stroke and subarachnoid hemorrhage, resulting in 21.393 9 and 2.344 7 million person years of DALY, respectively. Among them, except the 0-14 age group, the disease burden of different subtypes of stroke in men was higher than that in women. The disease burden of ischemic stroke was increased with age in both men and women, with the heaviest disease burden in ≥70 years group. The disease burden of intracranial hemorrhage and subarachnoid hemorrhage was the heaviest in males aged 50-69 years old, and in females aged ≥70 years and 50-69 years, respectively. Metabolic factors were the main risk factors in all ages of different stroke subtypes, and the most important risk factor was high systolic blood pressure. Other risk factors were different between men and women. Smoking, high body mass index, high low-density lipoprotein, and outdoor particulate matter pollution were the main risk factors for stroke in men, while high body mass index, outdoor particulate matter pollution, and high fasting blood glucose were the main risk factors of stroke in women. The main risk were different among different age groups. CONCLUSIONS The burden and attributable risk factors for different stroke subtypes are discrepancy in different gender and age groups. Targeted interventions should be conducted in the future to reduce the burden of stroke.

Objective:To investigate the efficacy of autologous fat grafting in the treatment of stable linear scleroderma.Methods:A retrospective analysis was performed on 40 patients with stable linear scleroderma who received autologous fat grafting from October 2017 to November 2020 in the Department of Dermatology, Xijing Hospital, Air Force Medical University. There were 22 males and 18 females, aged 12 - 36 (18.2 ± 4.82) years. Skin lesions involved the forehead in 16 cases, the perioral area in 4, the lower jaw in 2, the cheek in 9, the trunk in 5, and the lower limb in 4, and the size of depressed skin defects was 3 - 24 cm 3. The patients′ subjective satisfaction rate, the decrease in the size of depressed skin defects, and the incidence of adverse reactions after autologous fat grafting were analyzed during the follow-up. Results:Six months after the grafting, 40 patients were followed up and evaluated, and the size of depressed skin defects markedly decreased. The satisfaction rate for appearance improvement after the first grafting was 60% (24/40) ; 35 patients received the second grafting, with a satisfaction rate of 88.6% (31/35) ; 17 received the third grafting, with a satisfaction rate of 94.1% (16/17) ; the total satisfaction rate was 87.5% (35/40). After the grafting, local skin unevenness was observed in the grafting area in 3 patients, and in the liposuction area in 2. The incidence rate of postoperative adverse reactions was 12.5% (5/40) .Conclusion:Autologous fat grafting was markedly effective in the treatment of stable linear scleroderma.

Objective: To explore the relationship between handgrip strength (HGS) and pulmonary function (PF) in college students with sedentary lifestyle, so as to provide a reference for taking HGS as an essential factor of PF. Methods: In March 1-5, 2023, a total of 44 college students were recruited and were divided into the sedentary group (22) and exercise group (22) according to the International Physical Activity Questionaire (IPAQ), with 22 students in each group. Independent sample t-test was used to compare the indexes between groups, pearson correlation coefficient was used to determine the correlation between HGS and PF. Multiple linear regression analysis was used to determine the predictive model of PF. Results: There were statistical significance of the correlations between HGS and FVC, MEP, PEF, FEV1, FIVC, MIP, and PIF ( r=0.79, 0.47, 0.44, 0.60, 0.72, 0.53 , 0.49, P <0.01). When gender, physical activity, age, height, weight, and HGS were included as predictors in the regression model, height and HGS had significant effects on FVC ( R 2=0.75, F= 60.55 , P <0.01), weight and HGS had a good predictive effect on FIVC ( R 2=0.67, F=41.77, P <0.01). Conclusion HGS is significantly associated with PF in college students with sedentary lifestyle. Therefore, HGS can be used as an important indicator to predict the PF status of habitual sedentary college students.
