1.Consumption of ultra-processed foods and cardio-cerebrovascular diseases
International Journal of Cerebrovascular Diseases 2024;32(7):543-548
Ultra-processed foods (UPF) refer to ingredient formula foods made through complex industrial processes, which are essentially free of intact natural foods. The nutritional characteristics of UPF are high sugar, high salt, high fat, low protein, low dietary fiber, and low micronutrients, but it has attracted a large number of consumers due to its convenient consumption and tempting taste. With the advancement of urbanization and accelerated pace of life, the global consumption of UPF has rapidly increased in recent years, and the relationship between UPF and cardio-cerebrovascular diseases has begun to attract widespread attention. This article reviews the relationship between UPF consumption and the risk of cardio-cerebrovascular diseases, aiming to provide reference for dietary optimization of relevant populations.

OBJECTIVE:
To explore the clinical characteristics and genetic basis of a child with autism spectrum disorder (ASD) in conjunct with congenital heart disease (CHD).
METHODS:
A child who was hospitalized at the Third People's Hospital of Chengdu on April 13, 2021 was selected as the study subject. Clinical data of the child were collected. Peripheral blood samples of the child and his parents were collected and subjected to whole exome sequencing (WES). A GTX genetic analysis system was used to analyze the WES data and screen candidate variants for ASD. Candidate variant was verified by Sanger sequencing and bioinformatics analysis. Real-time fluorescent quantitative PCR (qPCR) was carried out to compare the expression of mRNA of the NSD1 gene between this child and 3 healthy controls and 5 other children with ASD.
RESULTS:
The patient, an 8-year-old male, has manifested with ASD, mental retardation and CHD. WES analysis revealed that he has harbored a heterozygous c.3385+2T>C variant in the NSD1 gene, which may affect the function of its protein product. Sanger sequencing showed that neither of his parent has carried the same variant. By bioinformatic analysis, the variant has not been recorded in the ESP, 1000 Genomes and ExAC databases. Analysis with Mutation Taster online software indicated it to be disease causing. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be pathogenic. By qPCR analysis, the expression level of mRNA of the NSD1 gene in this child and 5 other children with ASD was significantly lower than that of the healthy controls (P < 0.001).
CONCLUSION
The c.3385+2T>C variant of the NSD1 gene can significantly reduce its expression, which may predispose to ASD. Above finding has enriched the mutational spectrum the NSD1 gene.

Objective:To establish and validate a fluorescence focus assay (FFA) for rapid titration of Japanese encephalitis virus (JEV) and to evaluate its application in the production of Japanese encephalitis vaccine.Methods:Recombinant JEV non-structural protein 1 (NS1) was expressed in a prokaryotic expression system. After purification, JEV-NS1 was used to immunize rabbits to induce polyclonal antibody. FFA was established with the polyclonal antibody to titer JEV. The accuracy of FFA was validated by comparing with plaque assay, and the specificity, precision, linearity, range and robustness of FFA were also validated. Twenty-eight batches of live-attenuated Japanese encephalitis vaccine were titrated with FFA and plaque assay to analyze the relationship between the two assays.Results:FFA established with polyclonal antibody against JEV-NS1 could be used to titrate JEV, and there was no cross reaction with other viruses (tick-borne encephalitis virus, yellow fever virus, coxsackievirus A2, coxsackievirus A4). Results of the validation tests showed that FFA met the requirement of quality control for live-attenuated Japanese encephalitis vaccine. FFA was more consistency than plaque assay.Conclusions:The established FFA could be used for virus titration in the production of live-attenuated Japanese encephalitis vaccine.

Objective:To investigate the correlation between obstructive sleep apnea (OSA) and triglyceride-glucose (TyG) indexin patients with ischemic stroke.Methods:Patients with ischemic stroke underwent sleep breathing monitoring in Nanjing Stroke Registry Program from August 2020 to August 2021 were retrospectively enrolled. According to apnea-hypopnea index (AHI), the patients were divided into no/mild OSA group (AHI≤15 events/h) and moderate to severe OSA group (AHI>15 events/h). The TyG index was calculated according to triglycerides and fasting blood glucose, and the patients were grouped by quartile. The relationship between moderate to severe OSA and TyG index was determined by ordinal multinomial logistic regression analysis. Pearson correlation analysis was used to evaluate the correlation between TyG index and AHI. Results:A total of 155 patients with ischemic stroke were enrolled in the study, including 66 patients in the no/mild OSA group, 89 in the moderate to severe OSA group; 39 in the Q1 group (TyG index ≤8.46), 39 in the Q2 group (TyG index 8.47-8.78), 39 in the Q3 group (TyG index 8.79-9.17), and 38 in the Q4 group (TyG index >9.17). Ordinal multinomial logistic regression analysis showed that after adjusting for potential confounding factors, higher fasting blood glucose (odds ratio 2.370, 95% confidence interval 1.745-3.222; P<0.001) and moderate to severe OSA (odds ratio 2.377, 95% confidence interval 1.217-4.646; P=0.011) had significant independent positive correlation with TyG index. Pearson correlation analysis showed that AHI was positively correlated with the TyG index in patients with ischemic stroke ( r=0.209, P=0.011). Conclusion:OSA is independently correlated with TyG index in patients with ischemic stroke.

Objective:
To investigate the relationship between dietary polyunsaturated fatty acid (PUFA) intake and blood lipid, C-reactive protein (CRP) and homocysteine (Hcy) in patients with acute ischemic stroke or transient ischemic attack (TIA).
Methods:
Patients with acute ischemic stroke or TIA were enrolled consecutively from Nanjing Stroke Registry Program. The total dietary PUFA intake level was assessed by the food semi-quantitative frequency questionnaire. Venous blood samples were collected in the morning of the day after admission to the hospital to detect the levels of serum total cholesterol, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, Hcy, and CRP. According to the median level of total PUFA intake, the patients were divided into low PUFA group and high PUFA group. The relationship between PUFA intake and blood lipid, CRP and Hcy was analyzed by Spearman correlation analysis, and multiple linear regression analysis was used to determine the independent correlation.
Results:
A total of 170 patients (85.1%) with acute ischemic stroke and 31 patients with TIA (14.9%) were enrolled. Their age was 62.9±14.1 years, 143 were males (71.1%), and the median PUFA daily intake was 12.8 g (interquartile range: 8.05-17.5 g). Compared with the high PUFA group (

OBJECTIVE:
This study aimed to evaluate the clinical effect of periodontal microscopic surgery on the augmentation of attached gingiva and determined the clinical principle on how to use minimally invasive surgery to improve the surgery success rate.
METHODS:
Twenty patients with insufficient attached gingiva around implants were selected. Periodontal microscopic surgery for free gingival graft was performed to increase the width of the attached gingiva around the implants. The survival state of the free gingiva was observed after surgery, and the width of the attached gingiva around the implants was recorded before and after surgery and 1 year after surgery. The shrinkage rate of the free gingival flap 1 year after surgery was analyzed to evaluate the stability of the flap.
RESULTS:
The flaps of the 20 cases all survived. One year after the operation, the width of the attached gingiva was (3.05±0.44) mm, which increased compared with that of preoperation (2.56±0.31) mm
and decreased compared with that of postoperative day (2.13±0.28) mm. The shrinkage rate of the attached gingiva was 41.22%±5.04%.
CONCLUSIONS
The application of microscopic surgery on the augmentation surgery of attached gingiva can increase the success rate and improve the quality and quantity of attached gingiva around implants.

Epidemiological studies indicated that dietary tiber was inversely associated with stroke risk.Epidemiological studies have confirmed that increased dietary fiber intake can reduce the risk of stroke.Animal experiments and clinical studies have shown that dietary fiber intake may reduce the incidence of stroke by reducing vascular risk factors,such as hypertension,diabetes,dyslipidemia,and obesity.The direct mechanism of increased dietary fiber intake reducing stroke risk remains to be further studied.Clinicians should pay attention to the important role of dietary fiber,guide the patients with stroke and individuals at risk of stroke to increase consumption of fiber-rich fruits and vegetables.

Objective To investigate the relationship between the times of thrombectomy and the prognosis of acute ischemic stroke. Methods From June 2014 to June 2016,the clinical data of 61 consecutive patients with ischemic stroke treated with emergency endovascular thrombectomy in Jinling Hospital,Medical School of Nanjing University were collected retrospectively. According to the times of thrombectomy,they were divided into either a routine thrombectomy group ( <3, n =48 ) or a multiple thrombectomy group (≥3,n=13). The modified Rankin scale (mRS) was used to evaluate the neurological function prognosis at 90 d in both groups of patients. The mRS score 0-2 was defined as good prognosis,3-6 were defined as poor prognosis,and 6 was death. Univariate analysis was used to compare the differences between the groups (excluding the patients whose DSA data missing or of poor quality). Spearman correlation analysis was used to evaluate the relationship between the times of thrombectomy and prognosis and fatality rate. Results Univariate analysis showed that the recanalization rate of the patients in the routine thrombectomy group (73. 9%[34/46] vs. 25. 0%[3/12],P =0. 005) and the rate of good collateral compensatory (55. 6%[25/45] vs. 8. 3%[1/12],P =0. 004) were higher than those in the multiple thrombectomy group. The incidence of symptomatic intracranial hemorrhage in the routine thrombectomy group was lower than that in the multiple thrombectomy group (14. 6%[7/48] vs. 53. 8%[7/13],P =0. 003). The mortality rate at 90 days was 18. 0%(n=11). Further Spearman correlation analysis showed that the times of thrombectomy were moderately positive correlated with the mortality rate ( r=0. 517,P=0. 000). There was no significant correlation between the times of thrombectomy and the good function prognosis (r=0. 076,P=0. 560). However,the effects of the differences between recanalization rate,collateral compensation and symptomatic intracranial hemorrhage could not be ruled out. Conclusion Emergency intravascular interventional therapy of multiple thrombectomy is positively related to the mortality rate at 90 d in patients with acute ischemic stroke,however,a study with larger sample is needed to confirm it.

Objective To investigated the effect of the risk factors for stroke on the development of leptomeningeal colateral circulation in patients with middle cerebral artery occlusion. Methods Patients with acute ischemic stroke confirmed as middle cerebral artery occlusion by imaging were extracted from the Nanjing Stroke Registry Program between June 2006 and December 2011. The baseline clinical data were colected. Leptomeningeal colateral circulation was assessed by angiography. Results A total of 137 patients were enroled, including 100 males and 37 females; mean age 55. 26 ± 11. 71 years. The colateral circulation of 65 patients (47. 4% ) was good. Univariate analysis showed that the ages (52. 3 ± 13. 2 years vs. 57. 9 ± 9. 5 years; t = 2. 866, P = 0. 005) and the proportion of hypertension (52. 3% vs. 70. 8% ; χ2 = 4. 978, P =0. 026) in the good colateral circulation group were significantly lower than those in the poor colateral circulation group. Multivariate logistic regression analysis showed that age was an independent risk factor for affecting the leptomeningeal colateral circulation in patients with acute middle cerebral artery occlusion (odds ratio, 0. 965, 95% confidence interval 0. 934-0. 997, P = 0. 034). Conclusions Age is an independent risk factor for affecting the leptomeningeal colateral circulation in patients with middle cerebral artery occlusion.
