AIM: To investigate the correlation between fundus blood flow parameters and carotid artery ultrasound blood flow parameters in patients with hypertensive retinopathy(HRP).METHODS: A total of 50 patients(22 left eyes and 28 right eyes)with HRP admitted to our hospital from June 2021 to June 2023 were retrospectively included as the experimental group, and 50 healthy physical examination subjects(22 left eyes and 28 right eyes)during the same period were included as the healthy group. Pearson correlation was used to analyze the correlation between fundus blood flow parameters and carotid artery ultrasound blood flow parameters.RESULTS: The AUC values of fundus blood flow parameters and carotid artery ultrasound blood flow parameters and their combined diagnosis of HRP were 0.853, 0.844 and 0.935, respectively. Pearson correlation analysis showed that carotid systolic peak blood flow velocity was negatively correlated with foveal avascular zone(FAZ)area, FAZ circumference and non-circularity index, and positively correlated with macular vascular density(all P<0.05). The end-diastolic blood flow velocity was positively correlated with FAZ area and macular vascular density(all P<0.05). The internal carotid artery resistance index was positively correlated with FAZ area(P<0.05).CONCLUSION: The combination of fundus blood flow parameters and carotid artery ultrasound blood flow parameters in the diagnosis of HRP has good application value in the diagnosis of HRP.

Objective: To explore the iodine nutrition status of children in Wuhan from 2019 to 2023, and to evaluate the effect of iodine deficiency disorders control in focus groups in Wuhan, so as to provide a basis for consolidating elimination of iodine deficiency disorders. Methods: A total of 13 000 non boarding primary school students aged 8-10 were selected from 13 districts of Wuhan by stratified random sampling method.Household salt samples were collected to measure salt iodine content, random urine samples were analyzed for urinary iodine concentration. And B ultrasound was used to measure thyroid volume in students. The median of salt iodine, coverage rate of iodized salt, consumption rate of qualified iodized salt, median of urinary iodine, and the goiter rate were calculated. And Mann-Whitney U- test, Kruskal-Wallis H- test and Chi-square test were applied to compare between groups. Chi-square trend test was used to analyze the changing trends of coverage rate of iodized salt, consumption rate of qualified iodized salt and goiter rate among children in Wuhan. Results: The median of iodine content of children s household salt was 23.8 (21.7, 26.1) mg/kg, and the coverage rate of iodized salt was 98.7%, and the consumption rate of qualified iodized salt was 94.5 %. The consumption rates of qualified iodized salt showed an overall upward trend from 2019 to 2023 ( χ 2 trend =5.57， P <0.05). The median of urinary iodine of children was 220.1 (136.7, 326.0) μg/L,and boys had higher median of urinary iodine than girls [228.3(143.2, 336.0),210.2(129.1, 315.7) μg/L] ( Z =6.60, P <0.01). The median of urinary iodine of children in suburbs was higher than those in urban areas [236.3 (150.7, 342.2) , 207.1 (124.5, 309.8) μg/L]( Z =11.00, P <0.01). A total of 4 600 children were examined for thyroid volume, and the range of goiter rates were 1.1% to 3.4%, with an average goiter rate of 2.5%, which showed an overall downward trend from 2019 to 2023 ( χ 2 trend =5.11, P <0.05). Conclusions The iodine nutrition is sufficient and iodine nutrition status is good among children in Wuhan. It should continue to carry out monitoring and evaluation of children s iodine nutrition, guide the public to supplement iodine scientifically,so as to maintain the appropriate level of iodine for children.

Microglial functions are linked to Ca²⁺ signaling, with endoplasmic reticulum (ER) calcium stores playing a crucial role. Microglial abnormality is a hallmark of Alzheimer's disease (AD), but how ER Ca²⁺ receptors regulate microglial functions under physiological and AD conditions remains unclear. We found reduced ryanodine receptor 2 (Ryr2) expression in microglia from an AD mouse model. Modulation of RyR2 using S107, a RyR-Calstabin stabilizer, blunted spontaneous Ca²⁺ transients in controls and normalized Ca²⁺ transients in AD mice. S107 enhanced ATP-induced migration and phagocytosis while reducing ramification in control microglia; however, these effects were absent in AD microglia. Our findings indicate that RyR2 stabilization promotes an activation state shift in control microglia, a mechanism impaired in AD. These results highlight the role of ER Ca²⁺ receptors in both homeostatic and AD microglia, providing insights into microglial Ca²⁺ malfunctions in AD.

OBJECTIVE: Left ventricular remodeling induced by myocardial ischemia/reperfusion injury (MI/RI) is a common cardiac dysfunction. Accumulating evidence has demonstrated that autophagy plays a vital role in protecting against ventricular remodeling. This study aims to investigate the performance of Compound Danshen Tablets (CDT) in rescuing ventricular remodeling and whether autophagy as the potential mechanism. METHODS: The left anterior descending arteries of rats were temporarily ligated for 30 min to construct the MI/RI model. Ventricular remodeling was induced by reperfusion for 28 d, during which the MI/RI rats were administered CDT (300 mg/kg and 600 mg/kg), atorvastatin (2 mg/kg), and diltiazem (16 mg/kg). Cardiac function and structure were examined by echocardiography. Immunohistochemistry, Masson's trichrome staining, and hematoxylin-eosin (HE) staining were utilized to assess the fibrosis and histological alterations in the heart tissue. The expression of autophagy-related proteins was detected using Western blotting. RESULTS: CDT attenuated the cardiac dysfunction, structural changes, histopathological changes and fibrosis induced by MI/RI. CDT significantly enhanced the level of Beclin1 and microtubule-associated protein 1 light chain 3 beta (LC3β), and reduced p62 levels in MI/RI rats. Moreover, CDT significantly increased the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and inhibited mammalian target of rapamycin (mTOR) phosphorylation. CONCLUSION CDT ameliorated MI/RI-induced ventricular remodeling by activating autophagy and improving autophagic flux via the AMPK/mTOR signaling pathway.

Objective:To explore the value of serum matrix metalloproteinase-1 (matrix metalloproteinase-1), and phosphatase and tensin hmmlogydeleted on ten (PTEN), in predicting osteoporosis (OP) in women with gestational diabetes mellitus (GDM) .Methods:The clinical data of.218 pregnant women with GDM treated in Linyi People’s Hospital from Sep. 2019 to Feb. 2023 were retrospectively collected and included in the GDM group. Another 98 healthy pregnant women who underwent physical examination during the same period were selected as the control group. Age, body mass index (BMI), blood glucose related indexes and serum MMP-1 and PTEN levels were compared between the two groups. According to the occurrence of osteoporosis (OP) in the second and third trimester of pregnancy, the GDM group was divided into OP group and non-OP group. Logistic regression analysis was used to explore the influencing factors of OP in pregnant women with GDM in the second and third trimesters. ROC curve was drawn to analyze the predictive value of serum MMP-1 and PTEN levels for osteoporosis in GDM pregnant women in the second and third trimesters.Results:Body mass index (BMI), fasting blood glucose (FBG), glycated hemoglobin A1c (HbA1c) and serum MMP-1 and PTEN levels in GDM group were higher than those in control group, but BUA, SOS and SI were lower than those in control group ( t=6.18, 12.68, 9.91, 11.42, 7.70, 5.63, 5.76, 9.84, all P<0.05). Among 218 GDM women, 29 cases had OP and 189 cases did not have OP. There were no significant differences in fasting blood glucose, glycosylated hemoglobin, blood calcium, blood magnesium, or blood phosphorus between the two groups (statistical value: 0.96, 0.86, 1.35, 1.06, 0.49, P>0.05). Logistic regression analysis showed that age, abnormal increase of MMP-1 and PTEN levels were independent risk factors for OP in GDM women in the second and third trimesters [ OR (95% CI) =1.260 (1.103-1.440) ,1.075 (1.031-1.120) ,1.055 (1.023-1.089), all P<0.05]. ROC curve showed that the AUC of MMP-1 and PTEN in predicting OP in GDM pregnant women in the second and third trimesters were 0.824 and 0.777, respectively. The AUC of the combination of the two in predicting OP in GDM pregnant women in the second and third trimesters was 0.933, and the specificity and sensitivity were 83.04% and 93.48%, respectively, which were higher than those of single detection. Conclusions:MMP-1 and PTEN in early pregnancy may play a potential role in the prediction of OP in pregnant women with GDM. Close monitoring of MMP-1 and PTEN levels may provide new ideas for the clinical diagnosis and treatment of OP high-risk patients.

Objective:To learn about the thyroid volume and goiter status of adults in Wuhan, analyze related influencing factors, and provide a basis for revising the diagnostic criteria for adult goiter.Methods:From December 2019 to November 2021, a multi-stage cluster random sampling method was used in 13 districts of Wuhan. Two communities or townships were selected from each district, 100 permanent residents over 16 years old were selected from each community or township according to the inclusion and exclusion criteria for general information collection, thyroid ultrasound examination, urinary iodine detection and physical examination were performed, and the influencing factors of thyroid volume were analyzed.Results:A total of 2 578 adults aged 16 and older in Wuhan were selected, including 1 168 males and 1 410 females, with an average age of (41.79 ± 13.01) years old. The median thyroid volume (interquartile range) in adults was 6.36 (4.88, 8.11) ml, the rate of goiter was 0.70% (18/2 578), and the detection rate of thyroid nodules was 35.49% (915/2 578). The median urinary iodine (interquartile range) was 185.32 (107.93, 277.08) μg/L. According to Spearman correlation analysis, the thyroid volume of adults in Wuhan was positively correlated with their height, weight, body mass index (BMI), and body surface area (BSA, r = 0.12, 0.22, 0.21, 0.20, P < 0.001). Through multiple linear regression analysis, the regression equation was obtained: thyroid volume = 7.72 + 1.19 × thyroid nodules - 1.04 × gender + 0.15 × age group. Patients with thyroid nodules had a thyroid volume greater than those without, males greater than females, and the elderly group greater than the younger group. Conclusion:The goiter rate in Wuhan is relatively low, and factors such as gender, age, presence of thyroid nodules, height, weight, BMI, BSA and other body measurement are the influencing factors of thyroid volume.

BACKGROUND:Neuroinflammation is an important factor leading to secondary spinal cord injury,and microglia/macrophage pyroptosis is a significant part of post-spinal cord injury neuroinflammation.Studies have shown that microglia/macrophage undergoes pyroptosis after spinal cord injury,but the regulatory mechanism of circular RNA(circRNA)in microglia/macrophage pyroptosis after spinal cord injury remains unclear. OBJECTIVE:To investigate the role and mechanism of circRNA0005512 in regulating microglia/macrophage pyroptosis after spinal cord injury. METHODS:Female Wistar rats were divided into sham group and spinal cord injury group.Motor function was evaluated using the Basso,Beattie,and Bresnahan(BBB)scale.Cavity volume was assessed by hematoxylin-eosin staining.Differential expression of circRNA in spinal cord tissue was screened using RNA-sequencing and circ0005512 was validated by real-time PCR.Immunofluorescence,western blot assay,ELISA,and real-time PCR were performed to detect cell pyroptosis in the rats and lipopolysaccharide-induced microglial cell line HAPI cell models.Gene knockdown was used to confirm the regulatory role of circRNA0005512 in microglia/macrophage pyroptosis. RESULTS AND CONCLUSION:(1)Seven days after spinal cord injury,evident cavities were observed at the injury site.Immediately after spinal cord injury,the motor function of rats was completely lost.Over time,the motor function of rats in the spinal cord injury group gradually partially recovered,and there was a significant difference in BBB scores compared to the sham group.(2)Circ0005512 was significantly upregulated according to the results of the RNA-sequencing and confirmed in both the animal and cell models.(3)Immunofluorescence,western blot assay,real-time PCR,and ELISA confirmed the significant upregulation of cell pyroptosis markers(NLRP3,GSDMD,and caspase-1)in spinal cord injury tissue and lipopolysaccharide-induced HAPI cells.(4)In the cell model,knockdown of circ0005512 resulted in significantly decreased levels of cell pyroptosis marker-NLRP3.(5)The results above indicate that circ0005512 promotes pyroptosis in microglia/macrophages after spinal cord injury.
