Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.

Objective: To investigate the prevalence of undernutrition and its associated factors among left behind and non left behind primary and secondary school students in the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) areas of central and western China, so as to provide evidence for improving the nutritional status of children and adolescents. Methods: A survey was conducted among 123 782 students selected by random cluster sampling method in grades 3-9 from NIPRCES in central (Hebei, Shanxi, Heilongjiang, Jilin, Anhui, Jiangxi, Henan, Hunan, Hubei, and Hainan) and western (Gansu, Guangxi, Inner Mongolia, Ningxia, Tibet, Shaanxi, Guizhou, Sichuan, Xinjiang, the Xinjiang Production and Construction Corps, Yunnan, Qinghai, and Chongqing) China in 2023. Anthropometric measurements and questionnaires were used to assess nutritional and dietary status. The prevalence of undernutrition was compared between left behind and non left behind students by Chi square test, and associated factors were analyzed by three level Logistic mixed effects model. Results: The prevalence of undernutrition was 8.5% (4 326) in left behind students and 8.1% (5 905) in non left behind students. Three level Logistic mixed effect model analysis showed that whether left behind or non left behind, the undernutrition rates of primary and secondary students in western regions were higher than those of students in central regions [ OR (95% CI )=1.72(1.57-1.87),2.25(2.07- 2.43 )]; the undernutrition risk was lower for those whose fathers had a cultural level of high school or above [ OR (95% CI )=0.69(0.62-0.77),0.90(0.82-0.98)] or junior high school [ OR (95% CI )=0.72(0.66-0.79),0.92(0.85-0.99)] compared to those with primary school or below; picky eating or selective eating increased the risk of undernutrition [ OR (95% CI )=2.36(2.07-2.68),2.28(2.04-2.55)], and primary and secondary school students without nutritional content in health education classes had higher rates of undernutrition [ OR (95% CI )=1.12(1.03-1.23),1.09(1.01-1.17)](all P <0.05). Conclusion The prevalence of undernutrition is slightly higher in left behind primary and secondary students than in non left behind primary and secondary students in central and western NIPRCES areas, with variations across different characteristics.

Objective: To analyze the trends of the frequency of meat, egg, and milk consumption among rural primary and junior high school students in central and western China covered by the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) from 2015 to 2023, so as to provide basis for formulating more targeted nutrition intervention policies and health education strategies. Methods: Using data from six rounds of monitoring and evaluation (2015-2021 and 2023), the study included 323 870 students from grade 3 to 9 across 22 provinces (autonomous regions and municipalities) in central and western China. The consumption frequencies of meat, egg, and milk over the past week were collected via questionnaires. The Cochran-Armitage trend test was used to analyze temporal trends, and multivariable Logistic regression models were employed to analyze factors associated with the frequency of meat, egg and milk consumption and to test for interaction effects between the year and gender, region, and grade level. Results: From 2015 to 2023, the proportion of students consuming meat, egg, and milk ≥1 time/day increased from 23.20 %, 10.71%, and 0.74% to 35.53%, 22.09%, and 26.63%, respectively. Trend tests indicated a significant upward trend for the daily intake of all three food categories for meat, egg and milk over the years ( Z =67.18, 64.90, 93.14, all P <0.01). Multivariable Logistic regression analysis showed that the daily meat intake was lower in the central region than in the western region ( OR=0.77, 95%CI =0.76-0.78), whereas the daily intake of eggs ( OR=1.19, 95%CI =1.17-1.22) and milk ( OR= 1.27 , 95%CI =1.24-1.29) was higher in the central region (all P <0.05). Compared with grade 3-4 students, junior high school students had lower daily intake of meat, eggs, and milk≥1 time/day ( OR =0.95, 0.77, 0.77, all P <0.05), with a declining trend as grade increased. Girls also had lower daily intake of meat, eggs, and milk ≥1 time/day than boys ( OR =0.95，0.93，0.91, all P < 0.05). Significant interactions were observed between year and region, as well as between year and grade (all P <0.05). Conclusion From 2015 to 2023, the NIPRCES improved the intake level of among rural students, but the situation of relatively insufficient intake of egg and milk among females, junior high school students and those in the western region still exists.

Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder primarily caused by pathogenic variants in the TSC1 or TSC2 genes. It is characterized by multisystem hamartomatous lesions and neuropsychiatric manifestations. Here we report a young male patient with TSC involving multiple organs, caused by a heterozygous frameshift mutation in TSC2 (c.2071delC, p.Arg691Alafs^*7). The patient initially presented with classic facial angiofibromas and hypomelanotic macules, and subsequently developed psychiatric and behavioral disturbances with auditory hallucinations. Neuroimaging revealed an intracranial mass lesion, which was confirmed as a subependymal giant cell astrocytoma on postoperative histopathology following surgery performed at an outside institution. After admission, the patient underwent a comprehensive diagnostic workup, and multidisciplinary treatment evaluation revealed extensive multisystem involve-ment, including the nervous system, skin, kidneys, lungs, heart, eyes, pancreas, liver and bones. Combined with relevant literature, this article discusses the molecular mechanisms, clinical phenotypes, and comprehensive management of TSC, in order to provide a reference for the standardized and individualized management of this disease.

AIM: To evaluate the effectiveness and safety of compound anisodine combined with laser photocoagulation in the treatment of diabetic retinopathy(DR).METHODS: A prospective cohort study was used to select 80 patients(160 eyes)diagnosed with severe non-proliferative diabetic retinopathy(NPDR)and proliferative diabetic retinopathy(PDR)in Beijing Tongren Hospital, Capital MedTcal University and Beijing Daxing District People's Hospital from May 2023 to July 2023. They were divided into control group(40 cases, 80 eyes)and observation group(40 cases, 80 eyes)by random number table method. The control group only received 532 nm laser panretinal photocoagulation(PRP)treatment, while the observation group received PRP treatment together with superficial temporal subcutaneous injection of compound anisodine. The clinical efficacy, changes in hemorheology, changes in retinal blood vessels, and incidence of adverse reactions in the two groups were observed before and at 2 mo after treatment.RESULTS: The visual acuity, fundus changes and hemorheological parameters of the two groups were analyzed before and after treatment. There were no significant differences in the two groups before treatment(all P>0.05). The best corrected visual acuity of the observation group was better than that of the control group at 2 mo after treatment(P<0.05), and the clinical curative effect of fundus was also better than that of the control group(all P<0.05). The hemorheological indexes of central retinal artery blood flow(peak systolic velocity and end diastolic velocity)in the observation group were higher than those of the control group(all P<0.05), and the blood flow resistance index was lower than that of the control group(P<0.05).CONCLUSION: Compound anisodine combined with 532 nm laser photocoagulation is safe and effective in the treatment of DR, and the visual recovery effect is better.

Background and Objectives: There is no dedicated occlusive device for closing coronary artery fistulas (CAFs), and specific efficacy and safety data of various off-label occlusive devices for CAFs closure are scarce. Methods: Patients undergoing transcatheter closure of CAFs from January 2011 to December 2022 were included in the single-center retrospective study. The study population was divided into 2 groups: coils group (n=35) and patent ductus arteriosus (PDA) occluders group (n=66). Results: No significant intergroup differences were observed in demographic characteristics except age. The presence of multiple CAF origins (54.3% vs. 4.5%, p<0.001) and multiple draining sites (51.4% vs. 3.0%, p<0.001) were more common in the coils group. In contrast, the presence of aneurysm (72.7% vs. 14.3%, p<0.001), and large fistula (75.8% vs. 37.1%, p<0.001) were more prevalent in the PDA occluders group. The acute procedural success rate of the PDA occluders group was higher compared to that of the coils group (87.9% vs.62.9%, adjusted odds ratio [OR], 7.20; 95% confidence interval, 1.59–32.64; p=0.01).In addition, no significant intergroup differences were noted in both the recanalization rate (7.8% vs. 20%, p=0.107) and the reintervention rate (3.1% vs. 8.6%, p=0.342). Conclusions Transcatheter closure of CAFs using PDA occluders was associated with significantly higher acute procedural success rates compared to coil embolization with comparable late outcomes.

Objective:To evaluate the clinical efficacy of mitral valve transcatheter edge-to-edge repair (TEER) in patients with non-central degenerative mitral regurgitation (DMR).Methods:This retrospective study included patients with non-central DMR who underwent TEER at Fuwai Hospital between January 2021 and February 2024. Patients were categorized into two groups: the commissure-involved group and the non-commissure group, based on whether the mitral valve commissures were involved. Clinical data, surgical outcomes, and echocardiographic findings at 3 months postoperatively were collected and compared, and patients were followed up. The primary endpoint was the procedural success rate at discharge.Results:A total of 59 patients were included, aged (68.6±9.3) years, including 23 females (39%). In the overall study population, 78% (46/59) of patients had severe mitral regurgitation. Forty-two cases were in the non-commissure group, and 17 cases were in the commissure-involved group. Patients in the non-commissure group mainly had lesions in the A1/P1 region, while patients in the commissure-involved group mainly had lesions in the A3/P3 region. There was no significant difference in the procedural success rate at discharge (93% vs. 88%, P=0.95) and the incidence of postoperative complications (5% vs. 6%, P=1.00) between the two groups. Two patients in the commissure-involved group experienced single leaflet device attachment, with one of them requiring conversion to surgical mitral valve surgery; In the non-commissure group, two patients experienced single-valve clamping, and one of them was converted to surgical mitral valve surgery. The follow-up time of the entire cohort was (15.5±10.3) months. In the non-commissure group, 2 patients died and 2 were readmitted. While in the commissure-involved group, no patients died and only 1 patient was readmitted. Conclusion:TEER is an effective treatment for patients with non-central DMR involving the commissures, without increasing the incidence of postoperative complications.

Objective:To analyze the impact of achieving behavioral and metabolic factor control targets on cardiovascular disease (CVD) risk in hypertensive patients.Methods:This retrospective study utilized data from the National Enssential Public Health Service program in Kunshan City, Jiangsu Province. Hypertensive patients who participated in the program in 2018 were enrolled and divided into six groups accoding to the number (0-1, 2, 3, 4, 5, or 6) of controlled behavioral and metabolic factors (blood glucose, blood pressure, low-density lipoprotein cholesterol, obesity, smoking, and physical activity). Baseline data were collected from the 2018 health examinations and stratified intervention management records to analyze the distribution of characteristics across groups. Patients were followed up, with incident CVD during follow-up as the primary outcome. Competing-risk Cox proportional hazards regression model was employed to assess the impact of achieving behavioral and metabolic control targets on CVD risk. Differences in cumulative incidence of CVD between groups were compared using Gray′s test for equality of cumulative incidence functions. The population attributable fractions (PAF) for each behavioral and metabolic factors were calculated using the "averisk" package in R software.Results:A total of 87 338 hypertensive patients were included, aged (62.88±9.14) years, with 42 419 males (48.57%). During a follow-up of 75.0 (60.0, 77.0) months, 10 200 incident cases of CVD and 3 187 non-CVD deaths were recorded. The cumulative incidence of CVD was 13.69% (95% CI 13.35-14.03), with no statistically significant difference between males and females (13.99% vs. 13.41%, Pgray=0.246). Cox regression analysis revealed that after adjusting for confounders, the risk of CVD in hypertensive patients showed a decreasing trend with an increasing number of controlled behavioral and metabolic factors ( P for trend<0.001). Specifically, achieving all six control targets was associated with a 48% reduction in CVD risk ( HR=0.52, 95% CI 0.44-0.62, P<0.001) compared to achieving only 0-1 control targets. Moreover, the combined PAF of all six factors for CVD incidence was 23.98% (95% CI 19.99%-27.97%). Physical inactivity had the highest PAF (8.70% (95% CI 5.19%-12.21%)), followed by uncontrolled blood glucose (7.30% (95% CI 6.36%-8.25%)) and elevated low-density lipoprotein cholesterol (5.54% (95% CI 3.58%-7.50%)). Conclusion:Compared to achieving only 0-1 control targets, attaining all six behavioral and metabolic control targets was associated with a 48% reduction in CVD risk among hypertensive patients. Furthermore, controlling all six factors could prevent 23.98% of CVD cases in the hypertensive population. Therefore, multifactorial coordinated interventions should be prioritized as a core strategy in the National Essential Public Health Services Program to effectively achieve the goal of primary CVD prevention at the population level.

Zuotai is the most representative prepared product in Tibetan medicine,with functions such as treating diseases,detoxification,nourishing health,and enhancing efficacy.Zuotai and its formulations has become the core medicines for detoxification in Tibetan medical practice.Currently,research on Zuotai mainly focuses on the historical inheritance of processing techniques and exploration of safety,with relatively less research and confirmation on its detoxification effects.This study systematically organized the literature basis for the detoxification efficacy of"Zuotai"by collecting and compiling classical works of Tibetan medicine.It examined the detoxification effects of Zuotai based on the Tibetan medical theories of"Three Stomach Fires","Seven Essences and Three Impurities",and"Ro Nus ZhurJes"combined with the principles of toxic effects on the body and detoxification treatment.Using Tibetan medicinal property analysis methods,the study interpretd the"taste,nature,and efficacy"of Zuotai's processing ingredients and explored the Tibetan medical principles behind Zuotai's detoxification.The five sources of Zuotai are primarily"water"and"earth,"with the six tastes dominated by"sweetness,"and the seventeen efficacies mainly characterized by"heavy,blunt,cool,oily,stable,and soft".These properties counteract the"light,sharp,hot,fine,unstable,and rough"characteristics of toxins,thereby treating diseases caused by toxins,such as"Lung"and"Tripa"disorders,and restoring balance to the"Three Stomach Fires","Seven Essences and Three Impurities",and"Three Humors".Additionally,the raw materials of Zuotai possess intrinsic properties of detoxification,wound healing,and treating brain injuries,achieving the purpose of detoxification.This study preliminarily clarified the efficacy principles of Zuotai's detoxification,providing a theoretical reference for further research on its effectiveness,mechanisms,and clinical applications.
