Stroke is one of the leading causes of death and disability worldwide， ranking as the second leading cause of mortality globally and the primary cause of adult disability. Its pathological process involves complex cascade mechanisms， with high incidence and disability rates， posing a major threat to human health. According to statistics from the World Health Organization， more than 13 million new cases of stroke occur globally each year， resulting in direct medical costs and socioeconomic burdens amounting to hundreds of billions of dollars. In recent years， breakthroughs in the study of programmed cell death mechanisms have provided new insights into stroke treatment. Among them， ferroptosis， a novel form of cell death driven by iron-dependent lipid peroxidation， has attracted widespread attention in the pathological process of stroke. Ferroptosis is closely associated with iron metabolism disorders， oxidative stress， and lipid peroxidation， and exhibits unique regulatory effects in key pathological processes of stroke， such as ischemia-reperfusion injury， disruption of the blood-brain barrier， and neuronal apoptosis. It plays an important role in post-stroke neurological damage. Chinese medicine， as an essential component of traditional Chinese medicine （TCM）， has demonstrated advantages in modulating ferroptosis and exerting neuroprotective effects. This review systematically summarizes current research on the neuroprotective mechanisms of Chinese medicine compound formulas and monomers through the regulation of ferroptosis pathways in post-stroke conditions， aiming to provide a basis for optimizing clinical treatment strategies and exploring new therapeutic approaches， and to offer new strategies and approaches for stroke treatment.

Objective: To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD. Methods: Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model. Results: A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966). Conclusion The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

Objective:To investigate the iodine nutritional status of pregnant women in Hangzhou City and analyze its influencing factors, in order to provide a basis for guiding pregnant women in Hangzhou City to supplement iodine scientifically.Methods:A stratified random sampling method was used to conduct a questionnaire survey on 1 400 pregnant women in Hangzhou City from March to October 2018. Random urine samples and household salt samples from pregnant women were collected, and the levels of urine iodine and salt iodine were measured using arsenic cerium catalytic spectrophotometry and direct titration, respectively. The iodine nutritional status of pregnant women with different basic characteristics and dietary levels were analyzed and compared (Kruskal-Wallis test), and the main influencing factors affecting the urinary iodine concentration level of pregnant women were identified (the ordinal multiple classification logistic regression analysis).Results:The median urinary iodine of pregnant women was 135.00 μg/L, and the qualified iodized salt consumption rate of pregnant women was 83.36% (1 167/1 400). In terms of basic characteristics, there were statistically significant differences in the distribution level of urine iodine among pregnant women with different pregnancy frequency, delivery frequency, and natural abortion frequency ( P < 0.05). In terms of diet, the frequency of consuming milk, yogurt, meat, and whether pregnant women consumed cabbage and cauliflower showed statistically significant differences in urinary iodine distribution levels ( P < 0.05). Ordinal multiple classification logistic regression analysis showed that the urine iodine levels of pregnant women who were pregnant twice were higher than those who were pregnant ≥3 times ( OR = 1.64, P = 0.003). Pregnant women who never or occasionally consumed yogurt had lower urine iodine levels than or equal to those who consumed 2 bottles of yogurt per day ( OR = 0.53, P = 0.044). Pregnant women who never or occasionally consumed meat and those who consumed meat once a week had higher urinary iodine levels than that who consumed meat ≥2 times per week ( OR = 1.40, 1.47, P < 0.05). Conclusions:The overall iodine nutrition of pregnant women in Hangzhou City is at an deficiency level. Pregnancy experience and dietary level are influencing factors on iodine nutrition of pregnant women. It is necessary to carry out in-depth health education for pregnant women, improve the dietary structure during pregnancy, and improve the abnormal iodine nutrition of pregnant women.

Objective    To investigate the feasibility of magnamosis rings designed based on magnetic compression technique in esophageal anastomosis reconstruction. Methods    According to the anatomical characteristics of esophagus in SD rats, the esophageal magnamosis rings were designed. SD rats were used as animal models (n=10, 5 males and 5 females) to complete the magnetic anastomosis reconstruction of the cervical esophagus using magnamosis rings, and the operation time, animal survival, postoperative complications, magnetic rings excretion time were recorded. Two weeks after operation, the rats were killed, and the esophageal anastomotic specimens were obtained. The blasting pressure of the anastomotic site was measured and the formation of the anastomotic site was observed with naked eyes. Results    Esophageal magnamosis was successfully performed in 10 SD rats, and the median operation time was 11 (8-13) min. All rats survived without anastomotic leakage, anastomotic stenosis, or magnetic rings incarceration. The magnetic rings were discharged after 8 (5-10) days and the burst pressure was higher than 300 mm Hg. Visual observation showed that the anastomotic muscle healed well and the mucosa was smooth. Conclusion    The magnetic compression technique  can be used for anastomosis reconstruction of esophagus, which has the advantages of simple operation and reliable anastomosis effect, and has clinical application prospect.

Objective: A longitudinal study design was used to explore the effect of perceived discrimination on the psychological adaptation of children relocated to alleviate poverty. Methods: Four hundred twenty six children who were relocated to alleviate poverty were measured three times using a perceived discrimination questionnaire, childhood depression inventory, and the Illinois loneliness questionnaire, the data were analyzed using a cross lag model. Results: Depression and loneliness of children relocated to alleviate poverty had an increasing trend during the three surveys( F=18.79, 8.69, P <0.01). Perceived discrimination was positively correlated with depression and loneliness at the time points for the three surveys( r=0.23~0.55, P <0.01). Cross lag analysis showed that perceived discrimination in the pretest (Tn) significantly predicted posttest (Tn+1) depression ( β=0.16, 0.20, P < 0.01 ) and perceived discrimination at time 2 significantly predicted loneliness ( β=0.25, P <0.01) at time 3. Conclusion Perceived discrimination was shown to be an important factor affecting the psychological adaptation of children relocated to alleviate poverty.

Objective:To assess capacity of cardiovascular disease diagnosis and treatment service in primary health care (PHC) in Beijing-Tianjin-Hebei region.Methods:From September to December 2016, document acquisition and abstraction and in-person interviews were conducted on 327 PHC institutions and their medical staff from 43 districts/counties in the Beijing-Tianjin-Hebei region to comprehensively assess their infrastructure and services, human resources, health information system and drug availability related to cardiovascular disease diagnosis and treatment.Results:⑴ Infrastructure and services: 30.0% Community Health Center (CHC) and 100.0% Township healthcare center (THC) provided inpatient services, 20.5%, 98.1% village clinic (VC) could not provide blood glucose tests and lipid tests, respectively; ⑵ Human resources: in CHC, THC or CHS, 19.6% doctors' educational levels were below the requirement for a licensed assistant doctor, and in VC, 32.4% doctors' educational levels were below the requirement for village doctors. 56.3%CHC、THC and CHS, 99.5% VC could not provide government-funded " four insurances and one allowance" for non-registered staff, and 30.0% village doctors had exceeded 60 years old; ⑶ Health information system: 40.0% CHC, 41.7% THC, and 0 VC had electronic medical record (EMR), respectively; ⑷ Drug availability: 71.9% PHC institutions stored all four types of antihypertensive drugs [angiotensin-converting enzyme inhibitors/angiotensin receptor blockors (ACEIs/ARBs), β-blockers, calcium channel blockers (CCBS), diuretics], and 2.1% did not have any.Conclusions:The capacity of cardiovascular disease diagnosis and treatment services in PHC institutions in Beijing-Tianjin-Hebei region are fair in general, but efforts should still be made to enhance the infrastructure construction, improve the remuneration packages of PHC doctors, promote the comprehensive ability of PHC doctors, optimize the layout of urban and rural health resources, strengthen the information construction, and improve the joint development of medical system in the three cities and provinces.

【Objective】 To assess the prevalence and treatment of high cardiovascular disease （CVD） risk， and identify individual characteristics related to high CVD risk. 【Methods】 Based on the data of the China Patient-Centered Evaluative Assessment of Cardiac Events （PEACE） Million Persons Project （MPP） from 2016 to 2019， this study enrolled local residents aged 35 to 75 years from 39 counties or districts in Northwest China. Rates of high CVD risk and individual characteristics were assessed in the overall study population. Statin and aspirin use was also evaluated among those at high risk for CVD. Multivariable mixed models were fitted to evaluate the relationship between individual characteristics and high CVD risk. 【Results】 Among 364 537 participants， the average age was （54.6±9.7）years， and 5.8% was at a high risk for CVD. Multivariate mixed models showed that individuals who were currently using alcohol， overweight or obese tended to have a high risk for CVD， while married persons， those with a higher education level or a higher household income were correlated with a lower risk for CVD （all P<0.05）. Among high-risk persons， hypertension was the most prevalent risk factor （98.1%）， and only 1.3% and 3.5% reported their use of statins and aspirin， respectively. 【Conclusion】 Of the 364 537 participants， about 1 in 17 had a high risk for CVD. Among those at a high CVD risk， only less than 4% reported taking statins or aspirin. These findings indicate that there is still much room for risk mitigation in this population in China.
