[Analysis on the efficacy of dual vein induction therapy of Ustekinumab in complex perianal fistulizing Crohn's disease].

Objectives: To analyze the efficacy of dual vein induction therapy of Ustekinumab (UST) in complex perianal fistulizing Crohn's disease (PFCD). Methods: Clinical data of patients diagnosed with complex PFCD in the Second Affiliated Hospital of Wenzhou Medical University from January 2022 to March 2023 were retrospectively analyzed. After sufficient single intravenous infusion of UST (6 mg/kg) at week 0 and 8, every patient received single subcutaneous injection of UST 90 mg every 8 weeks for maintenance treatment. At week 8, 16, and 22-26, clinical outcomes of anal fistula were evaluated using perianal disease activity index (PDAI), and overall activity of the patients was evaluated using Harvey Bradshaw index (HBI). At week 22-26, Van Assche Index (VAI) was used to evaluate imaging outcome of anal fistula, and simplified endoscopic score of Crohn's disease (SES-CD) was employed to assess intestinal outcome events. The above indexes were compared in the patients before and after UST treatment. PFCD patients were divided into first-line UST treatment group and non first-line UST treatment group according to whether first-line UST treatment was used, the differences in anal fistula response rate and remission rate, intestinal response rate and remission rate as well as overall activity response rate and remission rate were compared between the two groups. Results: A total of 60 PFCD patients were included, including 46 males and 14 females, aged [M (Q1, Q3)] 25.0 (20.8, 30.0) years old. The clinical response rates of anal fistula [41.7% (25/60), 55.0% (33/60) and 63.3% (38/60), respectively, P=0.056] and the clinical remission rates of anal fistula [21.7% (13/60), 31.7% (19/60) and 43.3% (26/60), respectively, P=0.002] gradually increased at week 8, 16, 22-26. The overall activity response rates [53.3% (32/60), 70.0% (42/60), 83.3% (50/60), respectively, P=0.040] and the overall activity response rates [41.7% (25/60), 61.7% (37/60), 75.0% (45/60), respectively, P=0.001] also gradually increased at week 8, 16, 22-26. At week 22-26, the partial response rate and fistula healing rate of anal fistula imaging were 45.0% (27/60) and 38.3% (23/60), respectively. The endoscopic response rate and endoscopic response rate were 73.7% (44/60) and 45.0% (27/60), respectively. The endoscopic response rate of patients receiving first-line UST treatment [23 males and 8 females, aged 22.0 (21.0, 39.0) years] was higher than that of patients receiving non first-line UST treatment[23 males and 6 females, aged 26.5 (20.0, 30.0) years,87.1% vs 58.6%, P=0.013]. Conclusion: The dual vein induction therapy of UST could effectively improve the clinical efficacy in patients with complex PFCD.

[Self-reported quality of life in patients with coronary heart disease and analysis of the associated factors].

Objective: To investigate the quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

[The associations of cyclin-dependent kinase inhibitor 2B antisense RNA 1 gene polymorphisms with the risk of Crohn's disease in Chinese patients].

Objectives: The present study aimed to investigate the associations of cyclin-dependent kinase inhibitor 2B antisense RNA 1 (CDKN2B-AS1) gene polymorphisms with the risk of Crohn's disease (CD) in Chinese patients. Methods: From January 2012 to January 2021, a total of 207 CD patients and 545 age-and gender-matched healthy controls were collected from the Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University. The genotypes of CDKN2B-AS1 (rs1063192, rs10757274, rs10757278, rs1333048, rs2383207) were determined by matrix-assisted laser desorption ionization time-of-flight mass spectrometry technique. Unconditional logistic regression analysis was used to analyze the differences of CDKN2B-AS1 polymorphisms between CD patients and healthy controls, as well as their influences on the clinicopathologic characteristics of CD patients. The analyses for linkage disequilibrium and haplotype were further performed by Haploview 4.2 software. Results: The variant genotype (AG+GG) and variant allele (G) of rs1063192 were more prevalent in CD patients than in healthy controls (32.4% vs 24.8%, P=0.036; 18.8% vs 13.6%, P=0.011). The same conclusions were also drawn for homozygous variant genotype (GG) and variant allele (G) of rs10757274 when CD patients were compared with healthy controls (19.8% vs 12.8%, P=0.017; 45.2% vs 38.1%, P=0.012). According to the Montreal Classification Standards, CD patients were stratified into different subgroups. The homozygous variant genotype (GG) and variant allele (G) of rs10757278 were less frequent in the patients with stricturing CD or penetrating CD than in those with non-stricturing and non-penetrating CD (13.7% vs 29.9%, P=0.015; 37.7% vs 50.4%, P=0.022). However, all the correlations above were no longer significant after Bonferroni's correction (all P>0.05). The polymorphic loci of rs10757274, rs2383207, rs10757278, and rs1333048 were in close linkage disequilibrium with each other in CDKN2B-AS1 gene. Compared with healthy controls, the frequency of haplotype AGAC was decreased in CD patients (1.5% vs 4.5%, χ2=7.61, P=0.006), whereas the frequency of haplotype GGAC was obviously increased in CD patients (3.0% vs 0.6%, χ2=14.25, P<0.001). The stratified analysis further showed that the frequency of haplotype AGAC was higher in the patients with stricturing CD or penetrating CD than in those with non-stricturing and non-penetrating CD (3.1% vs 0.4%, χ2=5.31, P=0.021). Conclusions: The variations of CDKN2B-AS1 (rs1063192, rs10757274, rs10757278, rs1333048, rs2383207) may not independently affect the risk of CD. Among the haplotypes constructed by rs10757274, rs2383207, rs10757278, and rs1333048, the haplotype AGAC may reduce the risk of CD, whereas it may increase the risk of stricturing or penetrating in CD patients. In addition, the haplotype GGAC may increase the risk of CD.

[Efficacy and safety comparison between pro-urokinase and reteplase in the treatment of patients with acute ST elevation myocardial infarction].

Objective: To compare the efficacy and safety of pro-urokinase and reteplase in the treatment of patients with acute ST elevation myocardial infarction (STEMI). Methods: STEMI patients, who received intravenous thrombolytic therapy in Henan STEMI registry between September 2016 and August 2018, were eligible for this study. A total of 5479 patients from 66 hospitals were screened and patients were divided into pro-urokinase group (n=638) and reteplase group (n=702) according to thrombolytic drugs. Data including patient demographics, risk factors, medical histories, patient information at admission, in-hospital treatment, time delays, and clinical events were collected. The clinical recanalization rate, in-hospital mortality, in-hospital death or treatment withdrawal, in-hospital main adverse cardiovascular and cerebrovascular events (MACCE, death or treatment withdrawal, congestive heart failure, reinfarction and ischemic stroke) and post-thrombolysis bleeding were compared between the two groups. Bleeding events were evaluated with Bleeding Academic Research Consortium (BARC) criteria. Results: The median age [61.8 (53.2, 69.0) vs. 62.6 (52.1, 69.8), P=0.833] or the proportion of women [23.0% (147/638) vs. 25.1% (176/702), P=0.385] were similar between the pro-urokinase and reteplase groups. Clinical recanalization rates were similar between the pro-urokinase and reteplase groups [82.1% (524/638) vs. 84.9% (596/702), P=0.172], and there was no difference in the median time from onset to thrombolysis [194.5 (135.0,290.0) min vs. 190 (126.0,292.0) min, P=0.431] and the median recanalization time [95 (67.5,120.0) min vs. 95 (71.0,119.0) min, P=0.561] between the two groups. There was no significant difference in in-hospital mortality [5.5% (35/638) vs. 5.1% (36/702), P =0.770], in-hospital all-cause mortality, treatment withdrawal [8.9% (57/638) vs.7.7% (54/702), P=0.410], and in-hospital MACCE [13.0% (83/638) vs. 10.4% (73/702), P=0.137] between pro-urokinase and reteplase groups. However, the incidence of post-thrombolysis bleeding was significantly higher in reteplase group than in pro-urokinase group [7.8% (55/702) vs. 3.8% (24/638), P=0.002]. Further analysis found that the incidence of oral bleeding and the BARC grades 1-2 bleeding were significantly higher in reteplase group than in pro-urokinase group, whereas the incidence of cerebral hemorrhage was similar between the two groups [0.6% (4/638) vs. 0.4% (3/702), P=0.715]. The comparison of efficacy and safety outcomes between the two groups after adjusting for baseline characteristics using general linear mixed models was consistent with those before the adjustment. There was no significant difference in in-hospital mortality, in-hospital death or treatment withdrawal, in-hospital MACCE after adjusting for baseline characteristics and post-thrombolysis bleeding between the two groups. Conclusions: Pro-urokinase and reteplase have similar clinical efficacy in the treatment of STEMI. In terms of safety, the incidence of cerebral hemorrhage is similar, while the incidence of BARC grades 1-2 bleeding and oral bleeding is higher in reteplase group than in pro-urokinase group, which has no impact on in-hospital outcomes.

[Cross sectional study of familial hypercholesterolemia in dyslipidemia patients receiving lipid-lowering therapy: DYSIS-China subgroup analysis].

Objectives: To analyze the incidence, blood lipid levels and cardiovascular disease of familial hypercholesterolemia (FH) in dyslipidemia patients receiving lipid-lowing therapy from the DYSIS-China. Methods: Dyslipidemia International Study-China (DYSIS-China) database was re-analyzed according to the criteria of "Chinese guidelines for prevention and treatment of dyslipidemia in adults-2016 version". DYSIS-China database included 25 317 dyslipidemia out-patients who received at least one lipid-lowering drug for at least three months. All the patients were divided into three groups: unlikely HF, possible FH and definite FH according to the Dutch Lipid Clinic Network diagnostic criteria. Age, gender, lipids levels, drug use and complications were compared among the three groups. Factors were compared between Possible FH group and definite FH group in terms of age stratification. Results: A total of 23 973 patients with dyslipidemia were included. The average age was (64.8±9.9) years, 11 757 patients were females (49.0%). The proportion of unlikely FH in the total population was 20 561 (85.7%), possible FH was 3294 (13.7%), and the definite FH was 118(0.5%). Patients in the definite FH group (58.3±8.5 years) was younger than in unlikely HF(65.3±9.8 years) and possible FH(61.8±9.9 years) group. LDL-C ((5.6±1.9) mmol/L) levels were significantly higher in definite FH group than in unlikely HF ((2.5±0.9) mmol/L) and possible FH ((4.3±1.0) mmol/L) group. TC ((7.4±1.8) mmol/L) levels were also significantly higher in definite FH group than in unlikely HF ((4.3±1.0) mmol/L) and possible FH ((6.0±1.0) mmol/L) group. Percent of female sex, sedentary lifestyle and systolic blood pressure value were significantly higher in definite FH group than in other two groups (all P<0.05). Statin use was similar among the 3 groups. Prevalence of ischemic cardiomyopathy (70(59.3%)) was significantly higher in the definite FH group than in unlikely FH group7519 (36.6%) and possible FH group1149 (34.9%). The rate of hypertension (82 (69.5%)) was also significantly higher in the definite FH group than in unlikely FH group (2 063 (62.6%) and in possible FH group (13 928 (67.7%)). The possible FH group had the highest proportion of patients aged 55-64 years (1 146 (34.8%)), and the prevalence of hypertension 358 (76.8%), diabetes 189 (40.6%), ischemic heart disease 186 (39.9%), cerebrovascular disease 149 (32.0%) and heart failure 28 (6.0%) was the highest in patients over 75 years old. The definite FH group had the highest proportion of patients aged 55-64 years (49 (41.52%)), and the prevalence of ischemic heart disease (70 (59.3%)) was the highest in patients aged 45-54 years old group, there was no significant difference in the prevalence of diabetes,hypertension,heart failure,peripheral artery disease and cerebrovascular disease among different age groups. Conclusion: The detection rate of FH in Chinese patients with dyslipidemia is not low, the blood lipid level is poorly controlled, and the risk of cardiovascular disease is high in Chinses FH patients.

[An analysis of insomnia and its influencing factors in patients with acute coronary syndrome].

Objective: To investigate the current situation of insomnia in patients with acute coronary syndrome (ACS), and analyze the influencing factors of insomnia in the ACS patients, so as to provide information on the development of new strategies for the treatment of insomnia in ACS patients. Methods: This is a multicenter and prospective observational study. A total of 771 ACS patients who met the criteria were selected from March 2013 to June 2015. The baseline social demographic information, sleep quality questionnaire, general anxiety disorder scale-7(GAD-7),patient health questionnaire-9(PHQ-9), short-form 12 health survey questionnaire(SF-12), and enhancing recovery in coronary heart disease patients social inventory(ESSI) were completed within 7 days after admission. Logistic regression analyses were used to analyze the influencing factors of insomnia in ACS patients. Results: A total of 741 subjects with valid questionnaires were collected, including 510 males (68.8%) and 231 females (31.2%). Among them, 487 (65.7%) subjects had at least one insomnia symptom: 308 (41.6%) subjects had difficulty in falling asleep, 369 (49.8%) subjects were easy to wake at night, 116 (15.7%) subjects woke up earlier than they expected, 74 (10.0%) subjects experienced both woke up earlier and difficulty in falling asleep, and 53 (7.2%) subjects woke up earlier, woke up at night and had difficulty in falling asleep at the same time. Logistic regression analyses showed that before admission physical activity (OR =0.636, 95%CI 0.411-0.984), depression (OR=1.908, 95%CI 1.101-3.305) and low social support (OR=0.278, 95%CI 1.198-3.301) were independent factors of insomnia in ACS patients. Conclusions: Nearly 2/3 ACS patients have symptoms of insomnia. Difficulty in falling asleep and easy to wake up at night are the most common manifestations. Physical activity, depression and social support independently are associated with insomnia.

Ethnic Disparities in Dental Caries among Adolescents in China.

Comprehensive research on ethnic disparities in dental caries in China is limited. The aims of this cross-sectional study were to compare the levels of dental caries in adolescents between the Han ethnic group and ethnic minority groups in China and to explore the risk indicators for dental caries within ethnic subgroups. Data from the Fourth National Oral Health Survey in 2015, which covered all 31 province-level administrative divisions in mainland China, were used. The dental caries status in the permanent dentition of adolescents aged 12, 13, 14, and 15 y was measured using the decayed, missing, and filled teeth (DFMT) score, and sociodemographic characteristics and oral health-related behaviors were also collected. A total of 118,601 adolescents were included, with ethnic minority groups accounting for 13.15%. Of the Han and minority groups, the standardized prevalence of dental caries experience was 40.58% and 47.67%, and the mean DMFT scores were 0.97 and 1.28, respectively. According to the multivariate zero-inflated negative binomial regression analysis, the caries status of minorities was more severe than Han adolescents (adjusted prevalence rate ratio [PRR], 1.14; 95% confidence interval [CI], 1.10-1.18). This disparity was greater among adolescents who lived in rural areas, had mid-level economic status, and frequently consumed sugary beverages. After propensity score matchings, Uygur (PRR, 1.44; 95% CI, 1.25-1.67), Tibetan (PRR, 1.39; 95% CI, 1.3-1.48), and Yi (PRR, 1.24; 95% CI, 1.04-1.48) adolescents were significantly more likely to have caries than Han adolescents. Subgroup analyses revealed that gender, age, location of residence, economic status, region, consumption of sweet snacks and sugary beverages, and dental visit pattern were significantly associated with dental caries within ethnic minorities.

[Association of Breg cells and Treg cells with the clinical effects of Infliximab in the treatment of Chinese patients with Crohn's disease].

Objective: To explore the associations of regulatory B cells (Breg cells) and regulatory T cells (Treg cells) with the clinical effect of Infliximab in the treatment of Chinese patients with Crohn's disease (CD). Methods: From January 2017 to June 2019, a total of 32 CD patients at active stage and 33 age and gender-matched healthy controls were collected from the Second Affiliated Hospital of Wenzhou Medical University in this study. Approximate 5 ml of peripheral fasting venous blood was obtained from every subject. Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood. Then multi-color flow cytometry was applied to determine the proportion of Breg (CD3-CD19+IL-10+B cells) in B cells and the proportion of Treg (CD4+CD25+Foxp3+T cells) in CD4+T cells. Infliximab (5 mg/kg) was given intravenously at week 0, 2 and 6 to induce CD remission, and then maintained with the same dose of Infliximab every 8 weeks. And the proportions of Breg and Treg were examined at week 14 of Infliximab treatment, then compared with those of week 0. Simultaneously, C-reactive protein (CRP), leucocyte count, platelet count, erythrocyte sedimentation rate were detected in CD patients to assess the clinical effect at week 0 and 14 of Infliximab treatment. Results: Before infliximab treatment, compared with healthy controls, the proportion of Breg in B cells was significantly increased [(3.15±1.17)% vs (2.64±0.38)%, P=0.024)], and the proportion of Treg in CD4+T cells was significantly decreased [(2.15±0.49)% vs (4.25±0.41)%, P<0.001] in CD patients. And the proportion of Breg was positively related with the proportion of Treg in CD patients either at week 0 or week 14 of Infliximab treatment (r=0.628, P<0.001; r=0.749, P<0.001). At week 14 of Infliximab treatment, according to symptoms, Crohn's disease activity index (CDAI) and endoscopic mucosal healing, CD patients were classified as remission group (CDAI<150 and endoscopic mucosal healing, R group) and non-remission group (CDAI≥150 or mucosal non-healing group, N group). Compared with CD patients at week 0 of Infliximab treatment, both the proportion of Breg and Treg were significantly enhanced [(5.89±2.60)% vs (3.19±1.27)%, P<0.001; (4.59±0.72)% vs (2.08±0.47)%, P<0.001], whereas CDAI and CRP was significantly reduced [CDAI: (63.19±14.69) vs (195.62±58.13), P<0.001; CRP: (3.65±2.23) mg/L vs (29.80±30.06) mg/L, P<0.001] in R group at week 14 of Infliximab treatment. The proportions of Breg and Treg were negatively related with the CRP (r=-0.279, P=0.026; r=-0.406, P=0.001) and CDAI (r=-0.409, P=0.001; r=-0.708, P<0.001) in CD patients at week 0 and 14 of Infliximab treatment. At week 14 of Infliximab treatment, ROC curve analysis showed that the predictive value of "Breg+Treg" for the effect of Infliximab was higher than the other parameters (area under ROC: 0.782, cutoff value: 0.895 5, P=0.034). Conclusions: Breg cells and Treg cells are not only significantly correlated with CD disease activity, but the combined detection of the two types of immune cells has higher clinical value for predicting the effect of Infliximab in CD patients at active stage.
