Objective Intracranial hemorrhage(ICH),the second most common subtype of stroke,exacerbates the disruption of the blood-brain barrier(BBB),leading to vasogenic edema,plasma protein extravasation,and infiltration of neurotoxic substances.The clearance capacity of the brain plays a crucial role in maintaining BBB homeostasis and facilitating patient recovery after hemorrhage.This study aimed to investigate the effect of circadian rhythms on BBB function,neuronal damage,and clearance capabilities. Methods The transwell model and hemoglobin were co-cultured to simulate the BBB environment after ICH.After intervention with different light groups,neuronal apoptosis was determined,glial phagocytosis was analyzed,the expression of endogenous clearing-related proteins aquaporin 4(AQP4)and low-density lipoprotein receptor-related protein 1(LRP1)was detected by western blotting and immunofluorescence dual standard method,and the expression of the tight junction protein occludin and melatonin receptor 1A(MTNR1A)was quantitatively analyzed. Results Circadian rhythms play a key role in maintaining the integrity of the BBB,reducing oxidative stress-induced neuronal damage,and improving microglial phagocytosis.Meanwhile,the expression of occludin and MTNR1A in neurovascular unit(NVU)co-cultured with hemoglobin improved the expression of AQP4 and LRP1,the key proteins in the NVU's endogenous brain clearance system. Conclusion Circadian rhythm(alternating black and white light)protects the NVU BBB function after ICH,promotes the expression of proteins related to the clearance of the hematoma,provides new evidence for the clinical treatment of patients recovering from ICH,and improves the circadian rhythm to promote brain metabolism and hematoma clearance.

Objective: To explore the differences in the gut microbiota of primary school students with different levels of sugar sweetened beverage intake, so as to provide scientific evidence for better identification of health risks in children and the development of targeted health policies. Methods: In June 2022, a total of 192 healthy primary school students from Chengdu were selected using a stratified cluster random sampling method. The sugar sweetened beverage intake was assessed through a dietary frequency questionnaire. Based on the median daily sugar sweetened beverage intake, primary school students were categorized into a low intake group ( n =96) and a high intake group ( n =96). The gut microbiota in fresh fecal samples from the two groups of primary school students was analyzed using 16S rRNA high throughput sequencing, and the diversity and community structure differences in the gut microbiota were compared. Results: Children in the low intake group had a sugar sweetened beverage intake of (21.3±1.6) mL/d, while the high intake group had an intake of (269.6±37.3) mL/d. Diversity analysis results showed that there were no statistically significant differences between the low intake and the high intake group in terms of α diversity metrics: Observed_otus index [298.50 (259.75, 342.25), 305.50 (244.25, 367.75)], Goods_coverage index [1.00 (1.00, 1.00), 1.00 (1.00, 1.00)], Chao index [304.18 (260.75, 348.78), 305.88 (245.68, 370.88)], Shannon index [5.88 (5.29, 6.45), 5.71 (4.89, 6.28)] and Simpson index [0.95 (0.91, 0.97), 0.94 (0.88, 0.97)] ( Z =-0.64, -0.76, -0.54, -1.76, -1.67, P >0.05). Furthermore, no statistically significant difference was observed in β diversity between the two groups ( R 2=0.006, P >0.05). At the genus level, the abundance of Blautia [0.033 (0.018, 0.055)] and Fusicatenibacter [0.009 (0.005, 0.015)] were higher in the low intake group compared to the high intake group [0.024 (0.013, 0.041),0.006 (0.003, 0.011)]and differences were statistically significant ( Z =-2.52, -2.81, P <0.05). LEfSe analysis highlighted intergroup differences primarily in Blautia, Fusicatenibacter and Sarcina( LDA= 3.56,3.12,3.53, P <0.05). Conclusions There is no significant difference in the diversity and overall structure of the gut microbiota in primary school students with different levels of sugar sweetened beverage intake. However, there are species variations at the genus level. The information can serve as a scientific basis for identifying health risks in primary school students and formulating targeted health strategies.

Objective:To investigate the influence of the depth of invasion on the prognosis of pT1 stage mid-thoracic esophageal cancer patients undergoing left thoracotomy.Methods:Retrospectively analyze the clinicopathological data of 139 patients with pT1N0M0 stage of mid-thoracic esophageal cancer who meet the enrollment criteria. Firstly, the prognosis and influencing factors of the whole group were analyzed. The differences in prognosis, local recurrence and distant metastasis between PT1A and PT1B patients were compared, and the influence of different infiltration depth on prognosis and treatment failure of patients was analyzed. SPSS 19.0 statistical software was used for statistical analysis.Results:The 1-year, 3-year and 5-year overall survival(OS) and disease-free survival(DFS) were 95.0%, 87.8%, 82.0% and 91.4%, 84.2%, 77.0%, respectively. There were significant differences in OS( χ2=7.500, P=0.006) and DFS( χ2=7.354, P=0.007) at 1, 3 and 5 years between pT1a and pT1b patients. Cox multivariate analysis showed that pT stage and pathological type were independent prognostic factors for OS and DFS( P<0.05). There were no significant differences in OS( χ2=0.734, P=0.693) and DFS( χ2=0.7690, P=0.681) of pT1a tumors with different invasion depths. There were significant differences in OS( χ2=15.368, P<0.001) and DFS( χ2=27.470, P<0.001) at 1, 3 and 5 years of pT1b tumors with different invasion depths. The recurrence rate of pT1b(23.8%) was significantly higher than that of pT1a(5.3%)( χ2=5.274, P=0.022). The distant metastasis rate of the former(10.9%) was also significantly higher than that of the latter(0)( χ2=4.494, P=0.034). There were significant differences in local recurrence rate( χ2=17.051, P<0.001) and distant metastasis rate( χ2=15.460, P<0.001) among pT1b patients with different infiltration depths. Logistic multivariate analysis showed that the depth of infiltration was an independent factor affecting the occurrence of local recurrence in stage pT1b patients after treatment( P<0.001). Pathological type( P=0.003) and infiltration depth( P=0.027) were independent factors affecting the occurrence of distant metastasis. Conclusion:pT1a period and pT1b period after the prognosis and treatment of patients with different failure modes, and pT1b period in patients with different infiltration depth and the prognosis of patients and its failure mode after treatment significantly related, infiltration depth of pT1b period after treatment in patients with the independence of the influencing factors of failure, suggest that clinical doctors should pay attention to pT1b period in patients with postoperative adjuvant therapy. This conclusion needs to be confirmed by large prospective studies of cases.

Objective:To investigate the prognostic value and related factors of heart-type fatty acid binding protein (H-FABP) in patients with heart failure.Methods:A total of 877 consecutive patients who were admitted to heart failure care unit of Fuwai hospital and diagnosed as heart failure from July 2015 to July 2017 were enrolled in this study. Baseline serum H-FABP concentration was measured by fluorescence lateral flow immunoassay. According to serum H-FABP levels, patients were divided into three groups: low H-FABP group (H-FABP≤4.04 ng/ml, n=292), middle H-FABP group (H-FABP 4.04-7.02 ng/ml, n=292) and high H-FABP group (H-FABP≥7.02 ng/ml, n=293). The general clinical characteristics were collected and compared among the three groups. According to whether heart failure was caused by coronary artery disease or not, patients with heart failure were divided into ischemic heart failure and non-ischemic heart failure. Multivariate linear regression analysis was performed to explore the independent risk factors of H-FABP. The primary endpoint events were the composite of all-cause death or heart transplantation. Multivariate Cox regression analyses, receiver operating characteristic (ROC) curves, risk prediction tests with multivariate Cox regression model and Kaplan-Meier analyses were conducted to investigate the relationship between H-FABP and the prognosis of heart failure. Results:Multivariate linear regression analysis showed that age, coronary artery disease, alanine aminotransferase, uric acid and N-terminal pro-B type natriuretic peptide (NT-proBNP) were positively associated with H-FABP (β=0.012, 0.238, 0.001, 0.345 and 0.063 respectively,all P<0.05), while female, hemoglobin, albumin, sodium, and estimated glomerular filtration rate (eGFR) were negatively associated with H-FABP (β=-0.184, -0.006, -0.016, -0.034 and -0.006 respectively, all P<0.05). One hundred and nineteen patients (13.6%) lost to follow-up, and 246 patients (32.5%) suffered from all-cause death or heart transplantation during the median follow-up duration of 931 (412-1 185) days. Multivariate Cox regression analysis showed that baseline H-FABP (log 2H-FABP) level was the independent predictor of all-cause death or heart transplantation in patients with heart failure ( HR=1.39, P<0.001). ROC curves showed that baseline H-FABP was a predictor of all-cause death or heart transplantation in patients with heart failure within 3 months, 1 year and 2 years (areas under the curves were 0.69, 0.69 and 0.71 respectively), and the best cut-off values were 5.85 ng/ml, 6.54 ng/ml and 6.54 ng/ml respectively. Risk prediction test with multivariate Cox regression model showed that baseline H-FABP could provide additional prognostic value in predicting all-cause death or heart transplantation for patients with heart failure on top of basic model and baseline NT-proBNP ( P<0.001). Taking 6.54 ng/ml and trisected levels of H-FABP as cut-off values respectively, Kaplan-Meier analyses showed that the survival rates were significantly different among the two or three groups ( P<0.001). Subgroup analyses showed that baseline H-FABP (log 2H-FABP) level was an independent predictor of all-cause death or heart transplantation in patients with ischemic heart failure ( HR=1.74, P<0.001), as well as in patients with non-ischemic heart failure ( HR=1.28, P=0.027). Conclusions:Age, sex, coronary artery disease, hemoglobin, albumin, alanine aminotransferase, sodium, eGFR, uric acid and NT-proBNP are associated with H-FABP level. Baseline H-FABP level is an independent predictor of all-cause death or heart transplantation in patients with heart failure. On top of basic model and baseline NT-proBNP, baseline H-FABP could provide additional prognostic value in predicting adverse events for patients with heart failure.

Objective: To examine the prospective association between peripubertal diet quality and pubertal timing. Methods: Multivariate regression analyses were performed using data obtained from 1 588 SCCNG (Southwest China Childhood Nutrition and Growth) study participants, which included dietary data, anthropometric parameters, and information about potential confounders during peri puberty, two and four years before the onset of menarche or voice break. Dietary intake in peri puberty was assessed using a validated food frequency questionnaire. Diet quality was determined using the Chinese Children Dietary Index (CCDI), which measures adherence to current dietary recommendations. Age at menarche or voice break (M/VB) were used as pubertal markers. Results: The CCDI score ranged from 58.0 to 132.5 for girls and from 48.3 to 129.9 for boys. The pubertal markers consistently indicated that girls and boys with a higher peripubertal diet quality entered puberty later than their counterparts with lower CCDI scores (higher vs. lower CCDI tertiles: age at M was 13.1 years (11.2-13.3) and 12.5 years (12.0-13.9)(P<0.01); VB was 13.8 years (12.1-14.8) and 13.4 years (12.5-15.1)（P=0.03), after adjusting for paternal education level, energy intake, and pre pubertal body fat. Conclusion Children with a higher diet quality during peri puberty entered puberty at a later age. Dietary guidance and intervention are needed for better dietary quality among children during pubertal transition.

Objective:To understand the relationship between the disease condition of patients with coal-burning-borne endemic arsenic poisoning (abbreviated as coal-burning-borne arsenic poisoning) and serum lipid metabolism indicators.Methods:Using a case-control study method, in the coal-burning-borne arsenic poisoning village of Yuzhang Town, Qianxinan Prefecture, Guizhou Province, 204 patients with arsenic poisoning diagnosed according to the standard of "Diagnosis of Endemic Arsenicosis" (WS/T 211-2015) were included in case group, including 87 males and 117 females, aged(53.37 ± 8.06) years old; and they were divided into mild arsenic poisoning group (71 cases), moderate arsenic poisoning group (59 cases) and severe arsenic poisoning group (74 cases) according to the clinical grading. Another 63 residents were selected into control group in a non-arsenic-exposed village about 12 km away from the diseased village, including 23 males and 40 females, aged (53.78 ± 9.10) years old. A face-to-face questionnaire survey was conducted for each group of people, including basic information such as general demographic characteristics, smoking status, and drinking status; fasting peripheral blood was collected, and an automatic biochemical analyzer was used to detect serum total cholesterol (TC) and triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels.Results:There were significant differences of serum TC [(4.94 ± 1.00), (5.00 ± 0.99), (5.27 ± 0.94), (5.57 ± 1.07) mmol/L], TG [(2.17 ± 0.90), (2.25 ± 1.31), (2.66 ± 1.43), (2.78 ± 1.40) mmol/L], LDL-C [(2.51 ± 0.79), (2.74 ± 0.64), (2.97 ± 0.66), (3.15 ± 0.80) mmol/L], and HDL-C levels [(1.57 ± 0.55), (1.42 ± 0.43), (1.36 ± 0.42), (1.30 ± 0.38) mmol/L] in control group, mild, moderate and severe arsenic poisoning groups ( F = 5.83, 3.64, 9.72, 4.41, P < 0.01 or < 0.05). Among them, the serum TC level in severe arsenic poisoning group, serum TG and LDL-C levels in moderate and severe arsenic poisoning groups were significantly higher than those in control group ( P < 0.05); the serum HDL-C level in moderate and severe arsenic poisoning groups were lower than that in control group ( P < 0.05); the serum TC, TG and LDL-C levels in severe arsenic poisoning group were significantly higher than those in mild arsenic poisoning group ( P < 0.05). After linear trend test, serum TC, TG and LDL-C levels all showed an upward trend with the degree of arsenic poisoning ( Ftrend = 15.77, 10.14, 29.15, P < 0.05), and serum HDL-C level showed a downward trend with the degree of arsenic poisoning ( Ftrend = 12.75, P < 0.05). There were significant differences in the abnormal rates of serum TC, TG and LDL-C levels among control group and mild, moderate and severe arsenic poisoning groups (χ 2 = 21.16, 16.60, 8.29, P < 0.01 or < 0.05). Among them, the serum TC and TG levels abnormal rates in moderate and severe arsenic poisoning groups and serum LDL-C level abnormal rate in severe arsenic poisoning group were higher than those in control group ( P < 0.05), the serum TC, TG and LDL-C levels abnormal rates in severe arsenic poisoning group were higher than those in mild arsenic poisoning group ( P < 0.05). There was no significant difference of the serum HDL-C level abnormal rate among four groups (χ 2 = 2.11 , P > 0.05). The results of trend chisquare analysis showed that the abnormal rates of serum TC, TG and LDL-C levels presented an increasing trend with the degree of arsenic poisoning (χ 2trend = 19.90, 15.25, 7.63, P<0.05). The results of logistic regression analysis showed that the risk of abnormal serum TC level in patients with severe arsenic poisoning was 2.90 times that in control group [odds ratio ( OR) = 2.90, 95% confidence interval ( CI): 1.43 - 5.91], and the risk of abnormal serum LDL-C level in patients with severe arsenic poisoning was 2.87 times that in control group ( OR = 2.87, 95% CI: 1.22 - 6.71). Conclusion:There is a correlation between the disease condition of patients with coal-burning-borne arsenic poisoning and their dyslipidemia.

Objective:Comparative analysis of diabetes was carried out in coal-burning arsenic poisoning areas and non-arsenic exposed villages of Yuzhang Town, so as to explore the relationship between arsenic exposure and diabetes.Methods:Data of basic information of 594 people who were diagnosed and included in the diabetes management in Central Health Center of Yuzhang Town in Qianxinan Prefecture Guizhou Province in 2018 were collected. According to the "Standards for the Determination and Classification of Endemic Arsenic Poisoning Areas" (WS 277-2007), 11 administrative villages in the town were divided into 5 arsenic poisoning villages and 6 non-arsenic exposure villages. The prevalence (%) was used for statistical description.Results:In 2018, the prevalence of diabetes in Yuzhang Town was 1.74% (594/34 218), 1.38% (243/17 665) for men and 2.12% (351/16 553) for women, the gender difference was statistically significant (χ 2=27.794, P < 0.05). The prevalence of standardized diabetes in arsenic poisoning villages was 3.38%; the prevalence of standardized diabetes in non-arsenic exposure villages was 3.13%. After sex stratification analysis, the non-arsenic exposed villages were used as reference. The OR and 95% CI of diabetic patients in arsenic poisoning villages were 0.65 (0.50-0.81) for males and 1.35 (1.09-1.67) for females. Conclusions:The association between arsenic exposure and diabetes is related to gender. The risk of diabetes mellitus in women is higher than that in men.
