Objective: To explore the association between mediterranean diet (MD) patterns and dental caries among children and adolescents with neurodevelopmental disorders (NDD), so as to provide a basis for developing scientific anti caries strategies related to diet. Methods: From December 2021 to June 2024, a questionnaire survey, a three day 24 hour dietary review survey, oral health examination, physical development measurement and Childhood Autism Rating Scale (CARS) evaluation were conducted involving 147 children and adolescents aged 2-22 years with NDD from nine special education schools and rehabilitation institutions in Tianjin. Group comparisons were carried out using the Mann-Whitney U test, Chi-square test, or Fisher s exact probability method. The correlation between dietary quality and dental caries was analyzed by adopting multiple linear regression analysis and restricted cubic spline. Results: There were 46 children and adolescents (31.3%) in the non dental caries group and 101 children and adolescents (68.7%) in the dental caries group. The number of decayed missing and filled teeth (dmft) was 2.0 (4.0), and the MD score was 4.0 (2.0) points. There were 62 children and adolescents (42.2%) in the low MD scores group and 85 children and adolescents (57.8%) in the high MD scores group. There was no significant difference in MD scores between NDD children in the non dental caries group and those in the dental caries group [nondental caries group:4.0(2.0), dental caries group:4.0(2.0), Z= -0.14, P >0.05]. The MD scores and dmft exhibited increasing and then decreasing trend ( P total =0.02, P non lineary = 0.04 ). Children and adolescents with NDD in the MD high scores group had a lower number of dmft than those in the MD low scores group ( β= -2.00 , 95%CI =-3.39 to -0.62, P <0.05). However, in children and adolescents with NDD and CARS scores ≥30, the above association was insignificant ( β=-0.63, 95%CI=-0.29-0.15, P >0.05). Conclusion Children and adolescents with NDD who have dietary patterns similar to the Mediterranean diet, are found to have fewer dental caries, and this is observed among those with no or mild symptoms of autism spectrum disorder.

Objective To explore the effects of air pressure, humidity, wind, and sunshine on the incidence of cardiovascular and cerebrovascular diseases (CVD) in Guiyang, and to provide reference for the prevention of CVD. Methods Using CVD incidence data from September 2021 to August 2022 in Guiyang City and meteorological data including average air pressure, average humidity, wind, and sunshine during the same period, the effects of meteorological factors on CVD incidence were explored and the importance of each factor was analyzed. Results When air pressure was below 868 hPa, above 887 hPa, or between 877 and 883 hPa, and when air pressure dropped less than 5.3 hPa within 24 hours, there was a higher risk of CVD. When the humidity was above 81%, the wind speed was small (<1.2 m/s) or high (>4m/s), and there was less sunlight (less than 3 hours), the risk of CVD was higher. Low humidity (<60%) was not conducive to the onset of CVD. There were highest risks at lag 5~10 days and 4-25 days for high pressure and low sunlight, respectively. When the relative humidity was saturated, there was an immediate effect. When the wind speed was low and high, the immediate effect and hysteresis effects were significant. Among the above meteorological factors, the impact of 24-hour variation of pressure and high or low atmospheric pressure on the incidence of CVD was the most significant, while the impact of sunlight and humidity was the weakest. The impact of diurnal variations in wind and atmospheric pressure was not clear. Conclusion The impact of air pressure on the incidence of CVD does not exhibit a simple linear relationship. The risk of CVD is high in high humidity, low light, and moderate or strong winds. It is necessary to fully consider changes in meteorological factors for CVD prevention and control.

Objective To analyze the situation of blood lipid and blood routine parameters in patients with pneumoconiosis,and construct a column chart diagnostic model to explore their diagnostic value for pneumo-coniosis.Methods A total of 456 patients with pneumoconiosis admitted to the First Affiliated Hospital of Chongqing Medical and Pharmaceutical College from January 2022 to January 2024 were selected as the pneu-moconiosis group,while 462 healthy subjects exposed to dust during the same period were chosen as the con-trol group.Serum lipids and blood routine parameters related to pneumoconiosis were measured and compared between two groups.Univariate and multivariate Logistic regression analyzes were conducted to examine ser-um lipids and blood routine parameters associated with pneumoconiosis.A risk prediction model was construc-ted using logistic regression in machine learning,and the diagnostic efficacy of the column chart diagnostic model was evaluated by calculating the C-index through receiver operating characteristic(ROC)curve and plotting the model calibration curve based on Hosmer Lemeshow goodness of fit.Decision curve analysis(DCA)was used to assess the clinical practicality of the column chart diagnostic model.Results The levels of serum high-density ester protein cholesterol(HDL-C),cholesterol(TC),red blood cell(RBC),hematocrit(HCT),hemoglobin concentration(HGB),lymphocyte number(LYM),and lymphocyte percentage(LYM％)in the pneumoconiosis group were lower than those in the control group(P＜0.05).The levels of neutrophil-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),and systemic immune inflammation index(SII)were higher than those in the control group(P＜0.05).Multivariate Logistic regression analysis showed that HDL-C,LYM％,PLR,and SII were independent influencing factors for pneumoconiosis(P＜0.05).A column chart diagnostic model for the occurrence of pneumoconiosis was constructed using HDL-C,TC,LYM％,PLR,and SII as diagnostic factors.The ROC curve C-index of the diagnostic model was 0.84(95％CI:0.81-0.86),with sensitivity for diagnosing pneumoconiosis of 75.29％,specificity of 77.51％,posi-tive predictive value of 83.25％,and negative predictive value of 67.88％.Internal validation was conducted on the constructed column chart diagnostic model,with a validation set ROC curve C-index of 0.84(95％CI:0.80-0.87),sensitivity of 80.91％,specificity of 72.62％,positive diagnostic value of 79.46％,and negative diagnostic value of 74.39％.The calibration positive curve slope of the diagnostic model was close to 1,and in the fit test P＞0.05.DCA analysis showed that the diagnostic model had clinical practical value for risk diag-nosis of pneumoconiosis.Conclusion HDL-C,TC,LYM％,PLR and SII are independent influencing factors for pneumoconiosis.A column chart diagnostic model for the occurrence of pneumoconiosis is successfully constructed based on machine learning principles,and it has been verified to have high diagnostic efficiency.

TCM believes that spleen deficiency is the root cause of emotional abnormalities in chronic fatigue syndrome (CFS), and clinical treatment often involves the heart, liver and kidney. TCM therapy has a significant efficacy in CFS emotional abnormalities. It is mostly treated with oral administration of TCM, acupuncture, moxibustion and massage therapy. It may play a therapeutic role by improving oxidative stress and immune inflammation, regulating nerve-endocrine, controlling energy metabolism and other ways. It is suggested to establish the syndrome differentiation standard of CFS emotional abnormality in the future, so as to improve the accuracy of syndrome differentiation and treatment; form a perfect treatment guide or expert consensus to guide the standardized application of various internal and external treatment methods; explore objective indicators based on the pathogenesis, and focus on the morphological and functional changes of disease target brain regions with the help of neuroimaging techniques, so as to improve the diagnosis and prognosis evaluation of CFS; based on the guidance of TCM theory, improve the CFS emotional abnormal animal modeling method.

Objective:To analyze the association between the rs562556 polymorphism of the proprotein convertase subtilisin/kexin type 9(PCSK9)gene and the degree of coronary artery stenosis in the patients with acute myocardial infarction(AMI).Methods:A total of 200 patients diagnosed with AMI from January 2021 to December 2022 were selected as AMI group,and 200 healthy individuals during the same period were selected as control group.According to the Gensini scoring standard,the patients in AMI group were divided into low risk group(Gensini score≤40,n=78)and medium-high risk group(Gensini score>40,n=122).The levels of lipid metabolism indicators in serum of the patients in two groups were detected by fully automatic biochemical analyzer;enzyme linked immunosorbent assay(ELISA)method was used to detect the PCSK9 levels in serum of the patients in two groups;ultraviolet spectrophotometry was used to detect the single nucleotide polymorphism(SNP)of PCSK9 gene of the patients in two groups;Spearman correlation analysis was used to detect the correlation between the rs562556 polymorphism of the PCSK9 gene and the degree of the disease and the levels of lipid metabolism indicators in serum of the patients.Results:Compared with control group,the percentage of smokers of the patients in AMI group was significantly increased(P<0.01).Compared with control group,the levels of low-density lipoprotein cholesterol(LDL-c)and PCSK9 in serum of the patients in AMI group were significantly increased(P<0.05).Compared with low risk group,the levels of LDL-c and PCSK9 in serum of the patients in medium-high risk group were significantly increased(P<0.05).The distribution of PCSK9 gene rs1800487 genotype in both control and AMI groups conformed to the Hardy-Weinberg(H-W)equilibrium(χ2=0.677,P=0.713;χ2=0.970,P=0.831).Compared with control group,the distribution frequencies of PCSK9 gene rs562556 genotype AA and allele A of the patients in AMI group were significantly increased(P<0.05).In the AMI patients,the distribution of PCSK9 gene rs562556 genotype in both low risk and medium-high risk groups conformed to the H-W equilibrium(χ2=0.045,P=0.978;χ2=1.290,P=0.525).Compared with low risk group,the distribution frequencies of genotype AA and allele A of PCSK9 gene rs562556 of the patients in medium-high risk group were significantly increased(P<0.05).The PCSK9 gene rs562556 genotype AA was positively correlated with the degree of AMI(r=0.193,P=0.006)and LDL-c level(r=0.301,P<0.01).Allele A was positively correlated with the LDL-c level(r=0.168,P=0.017).Conclusion:The PCSK9 gene rs562556 genotype AA is positively correlated with the degree of coronary artery stenosis of the AMI patients,and its polymorphism may promote the development of AMI by upregulating the LDL-c level.

Objective:To explore the role and mechanisms of action of human circular RNA 0001400 (hsa_circ_0001400) and its linear transcript RELL1 in the development of Kaposi's sarcoma (KS) .Methods:KS-associated herpesvirus (KSHV) was induced and extracted from BCBL-1 cells by phorbol ester. Human umbilical vein endothelial cells (HUVECs) were then infected with KSHV, inverted microscopy and real-time fluorescence-based quantitative PCR (qRT-PCR) were performed to observe cellular morphology and determine the expression of KSHV lytic gene ORF50 and latent gene LANA, respectively, so as to verify whether the infection was successful. HUVECs in the logarithmic growth phase were divided into 3 groups: HUVEC group (uninfected HUVECs), KSHV + HUVEC group (HUVECs infected with KSHV at a multiplicity of infection [MOI] of 0.5), and mitogen-activated protein kinase (MAPK) inhibitor group (HUVECs infected with KSHV at a MOI of 0.5 for 6 hours, followed by the treatment with 1 μmol/L MAPK inhibitor). Cell counting kit (CCK8) assay and flow cytometry were performed to assess the cellular proliferative ability and detect apoptosis in the above 3 groups, respectively. qRT-PCR and Western blot analysis were conducted to determine the transcription and protein expression levels of hsa_circ_0001400, its linear transcript RELL1, and rat sarcoma viral oncogene homolog (RAS) /MAPK signaling pathway-related genes in the HUVEC group and KSHV + HUVEC group. Five pairs of KS tissues and paraneoplastic tissues were collected, and mRNA expression of the above genes was verified by qRT-PCR in the KS tissue samples. Statistical analyses were performed using two-way analysis of variance, one-way analysis of variance, and t test. Results:Compared with the uninfected HUVECs, the infected HUVECs became rounder and grew more densely at 48 hours after the infection with KSHV. The mRNA expression of ORF50 and LANA genes could be detected in the KSHV-infected HUVECs, and their mRNA expression levels were significantly higher than those in the uninfected HUVECs (both P < 0.001), indicating successful infection of HUVEC by KSHV. The cellular proliferative rate in the KSHV + HUVEC group gradually increased over time during 24 to 72 hours after the infection, while that in the MAPK inhibitor group was markedly inhibited. The total apoptosis rate at 48 hours significantly differed among the 3 groups ( F = 673.98, P < 0.001), and was significantly higher in the MAPK inhibitor group than in the KSHV + HUVEC group and the HUVEC group (both P < 0.001), while there was no significant difference between the KSHV + HUVEC group and the HUVEC group ( P > 0.05). qRT-PCR showed that the mRNA expression of hsa_circ_0001400, RELL1, Kirsten rat sarcoma viral oncogene homologue (KRAS), MAPK11, and extracellular signal-regulated kinase (ERK) -2 was significantly higher in the KSHV + HUVEC group than in the HUVEC group (all P < 0.05), while ERK1 mRNA expression did not significantly differ between the 2 groups ( t = 0.92, P = 0.410). Western blot assay showed that the protein expression of RELL1, KRAS, MAPK11, ERK1, and ERK2 was significantly higher in the KSHV + HUVEC group than in the HUVEC group (all P < 0.01). The mRNA expression of RELL1, ERK1, and ERK2 was significantly higher in the KS tissues than in the paraneoplastic tissues (all P < 0.05) . Conclusion:KSHV infection may regulate the occurrence and development of KS by inducing the expression of hsa_circ_0001400 and its linear transcript RELL1, as well as activating the MAPK signaling pathway.
