Objective:To investigate the association between single nucleotide polymorphism (SNP) of the protein phosphatase 1 regulatory subunit 1B( PPP1R1B) gene and schizophrenia in the Han population of northern Henan province. Methods:Utilizing Psychiatric Genomics Consortium 3 (PGC3) data, the SNPs of PPP1R1B gene which were significantly associated with schizophrenia were screened.Subsequently, totally 1 721 schizophrenia patients and 6 726 healthy controls from the Han population in northern Henan province were recruited for further analysis. The SNP rs907094, located within the PPP1R1B gene was validated, and the clinical symptoms of 386 schizophrenia patients were evaluated using the positive and negative syndrome scale (PANSS). Additionally, expression quantitative trait loci (eQTL) association analysis was conducted to explore the relationship between the rs907094 polymorphism and PPP1R1B gene expression.The PLINK v1.9, Genetic Power Calculater, SPSS 20.0 softwares were used for data analysis. Results:Significant differences in genotype AA, AG, GG(schizophrenia group: AA, 489(28.4%); AG, 848(49.3%); GG, 384(22.3%); control group: AA, 1 450(21.6%); AG, 3 386(50.3%); GG, 1 890(28.1%), χ2=45.418, P<0.05) and allele frequency(schizophrenia group: A, 1 826(53.1%); G, 1 616(46.9%); control group: A, 6 286(46.7%); G, 7 166(53.3%), χ2=43.877, P<0.05) were observed for SNP rs907094 between the schizophrenia group and control group. Individuals carrying allele A were identified to have a higher risk of developing schizophrenia compared to those carrying allele G ( OR=1.288, 95% CI=1.195-1.388). Furthermore, the genotype PPP1R1B gene was found to be associated with the clinical features of schizophrenia. A statistically significant difference was observed in the excitement/hostility factor between AA and GG patients with rs907094 (13.62±5.65, 15.54±4.66)( P<0.05). Additionally, significant differences were noted in the cognitive factor scores between AA and GA genotypes (17.76±5.58, 19.43±5.73)( P<0.05). Conclusions:In the Han population from northern Henan province, the rs907094 polymorphism of the PPP1R1B gene is associated with schizophrenia.And the specific locus may be implicated in arousal/hostility symptoms and cognitive dysfunction.

Objective:To establish a multi-factor prediction model for vascular aging based on psychological behavior and physical exercise using nomogram and structural equation method.Methods:A total of 701 inpatients or physical examination patients who underwent carotid ultrasound examination in the Affiliated Hospital of Qingdao University from October 2021 to March 2023 were selected by cross-sectional method. The subjects were randomly divided into training queue( n=492) and verification queue( n=209) according to the ratio of 7∶3.The psychological and behavioral factors, lifestyle, demography and accompanying diseases data were collected. Multi-factor binary Logistic regression method in SPSS 25.0 software was used to screen independent influencing factors of vascular aging, R 4.2.2 software was used to build a nomogram prediction model of vascular aging, and the ROC curve, calibration chart and decision curve analysis were used to evaluate the nomogram, and AMOS software was used to build a structural equation model of vascular aging. Results:Multivariate Logistic regression analysis showed that type A behavior( B=1.757, OR(95% CI)=5.790(2.750-12.210), P<0.001), physical exercise( B=-3.019, OR(95% CI)=0.050(0.020-0.100), P<0.001), high-fat diet( B=0.679, OR(95% CI)=1.970(1.350-2.880), P<0.001), sleep quality( B=-1.451, OR(95% CI)=0.230(0.120-0.460), P<0.001), tea drinking habits( B=-2.349, OR(95% CI)=0.100(0.050-0.200), P<0.001), age( B=0.061, OR(95% CI)=1.060(1.020-1.110), P=0.005), sex( B=-1.263, OR(95% CI)=0.280(0.140-0.570), P<0.001), hyperlipidemia( B=0.679, OR(95% CI)=1.970(1.350-2.880), P<0.001) and diabetes( B=0.838, OR(95% CI)=2.310(1.140-4.700), P=0.021)were independent influencing factors of vascular aging. The nomogram model showed that type A behavior, physical exercise, high-fat diet, sleep quality, tea drinking habits, age, sex, hyperlipidemia and diabetes were independent influencing factors of vascular aging.Advanced age, type A behavior, hyperlipidemia, diabetes and the score of high-fat diet were risk factors for vascular aging, while better sleep quality, tea drinking habit and the score of physical exercise were protective factors for vascular aging.Men were more prone to vascular aging than women. Structural equation model showed that type A behavior had the strongest direct positive effect on vascular aging (the effect coefficient=0.197, P<0.01), and physical exercise had the strongest direct negative effect on vascular aging (the effect coefficient=-0.452, P<0.01), which could indirectly affect vascular aging through various factors. Conclusions:The nomogram model shows the independent influencing factors of vascular aging and has certain predictive value.Structural equation model shows that many factors such as psychological behavior and lifestyle can directly or indirectly affect the occurrence of vascular aging, among which type A behavior and physical exercise have more extensive effects.

Objective:To investigate the efficacy, safety and possible mechanisms of celecoxib as an adjunctive treatment for schizophrenia.Methods:90 schizophrenic inpatients at the second affiliated hospital of Xinxiang Medical College from April 2019 to October 2020 were recruited and randomly assigned to a placebo group or the celecoxib adjunctive treatment group using a random number table. In the placebo group, 46 patients (29 males, 17 females; aged 21-34, mean age 27.46±6.50 years) completed a 6-week follow-up. In the celecoxib group, 44 patients (32 males, 12 females; aged 21-39, mean age 30.52±8.69 years) completed a 6-week follow-up. The Positive and Negative Syndrome Scale (PANSS) was used to assess psychiatric symptoms in both groups. Changes in PANSS score at the end of the treatment were compared to evaluate the efficacy of celecoxib. Metabolic indicators such as weight, body mass index, waist circumference and plasm glucolipid, as well as cardiovascular indicators like blood pressure, electrocardiogram and routine blood tests, and adverse events were collected for the safety evaluation. Serum tumor necrosis factor-α (TNF-α), Interleukin-4 (IL-4) and interferon-γ (IFN-γ) were also tested. Pearson correlation analysis was used to explore the relationship between cytokine levels, PANSS score, PANSS reduction rate [(pre-treatment score-post-treatment score)/pre-treatment score×100%], and the safety measurements in the two groups, analyzing the role of inflammation in celecoxib adjunctive therapy.Results:The change of PANSS positive score at the end of the 6th week was significantly higher in the celecoxib adjuvant treatment group than in the placebo group (-8.00±6.12 vs -4.78±5.19, H=-0.55, P=0.009). The weight changes, body mass index, total cholesterol, and triglycerides over 6 weeks were significantly lower in the celecoxib group compared to the placebo group ( F=-7.37, -7.30, 2.56, -2.54; all P<0.05). No serious adverse events were found in celecoxib adjuvant therapy. In the placebo group, baseline TNF-α levels were positively correlated with baseline negative symptoms and PANSS reduction rate ( r=0.260 and 0.330, both P<0.05), and negatively correlated with the 6-week weight ( r=-0.311, P<0.05); baseline IL-4 levels were positively correlated with the 6-week PANSS total score and the 6-week PANSS negative score ( r=0.320 and 0.397, both P<0.05), and negatively correlated with PANSS reduction rate and 6-week blood glucose ( r=-0.316 and -0.331, both P<0.05); Six-week IFN-γ levels were negatively correlated with low-density lipoprotein levels ( r=-0.306, P<0.05). And no such correlation was found in celecoxib adjuvant group. Conclusion:Celecoxib adjunctive therapy can improve positive symptoms of schizophrenia without causing adverse reactions. Inflammatory state is related to schizophrenia symptoms, treatment efficacy and metabolic abnormalities.

Objectives:To investigate the association between single nucleotide polymorphisms (SNP) of indoleamine 2,3-dioxygenase( IDO) genes and schizophrenia (SZ) in a Chinese Han population. Methods:Using a case-control study method, 3 700 in-patients with SZ were recruited from January 2010 to December 2021 at the Second Affiliated Hospital of Xinxiang Medical University, and 8 580 healthy controls were recruited from surrounding communities in Xinxiang City. The patient group and control group were matched in gender and age. After collecting peripheral blood from all subjects and extracting genomic DNA, the sample DNA was genotyped using methods such as gene chips and amplification refractory mutation system. The association analysis between IDO gene SNPs and SZ was conducted using the online analysis tool SHEsis. The differences in IDO gene SNP genotype and allele frequency between the two groups were compared using chi-square test. Linkage disequilibrium analysis, haplotype analysis, and Hardy Weinberg equilibrium test were performed using Haploview v4.2 software. A multifactor dimensionality reduction software was used to evaluate the interaction between SNPs and SNP frequencies. Results:In the four SNP loci of IDO gene, there was a significant difference in genotype and allele frequency between the SZ patient and the health control at rs9657182 locus (χ 2=11.81, P=0.003;χ 2=5.54, P=0.019). After Bonferroni correction, the genotype difference at rs9657182 locus still showed statistical significance ( P=0.011). There were no statistically significant differences in genotype and allele frequency among the three SNP locis (rs7820268, rs4503083, and rs10109853). Further stratified by gender, there was no significant difference in genotype frequency between the two groups at the rs9657182. Haplotype analysis revealed that the haplotype of CC and TC (rs9657182 and rs7820268) were significantly different between the two groups (χ 2=3.93,4.78, P=0.048, 0.029). Conclusion:The rs9657182 locus of IDO gene may be a susceptible locus for SZ. The haplotype of CC and TC may be associated with the onset of SZ.
