Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for ulcerative colitis (UC) and elucidate its mechanism by targeting the vitamin D receptor (VDR) signaling pathway. Methods: A total of 63 patients with UC were randomly divided into an observation group (30 cases, treated with herbal cake-partitioned moxibustion) and a control group (33 cases, treated with sham herbal cake-partitioned moxibustion). Moxibustion treatment was performed at Qihai (CV6) and bilateral Tianshu (ST25) and Shangjuxu (ST37), 3 times per week for 12 weeks. The total effective rate, visual analog scale (VAS) score for abdominal bloating and pain, and hospital anxiety and depression scale (HADS) score were compared between the two groups. Enzyme-linked immunosorbent assay was used to detect the concentrations of serum C-reactive protein (CRP), 25-hydroxyvitamin D [25(OH)D], and interleukin-12 (IL-12)/interleukin-23 (IL-23) p40. Immunohistochemistry was used to observe the expression levels of VDR and regenerating gene Ⅳ (Reg Ⅳ) proteins in colonic mucosa. The expression levels of VDR, cytochrome p45027B1 (CYP27B1), and Reg Ⅳ mRNAs were detected by real-time fluorescence quantitive polymerase chain reaction. Results: After treatment, the total effective rate in the observation group was 86.7％, which was significantly higher than 51.5％ in the control group (P<0.05). After treatment, the VAS scores for abdominal bloating and pain in the observation group were significantly decreased (P<0.01), as well as the HADS-depression subscale (HADS-D) and HADS-anxiety subscale (HADS) scores (P<0.05), while only the VAS score for abdominal pain in the control group was reduced (P<0.05), and the improvements of the scores in the observation group were more significant than those in the control group (P<0.05). After treatment, the serum CRP concentrations in both groups and the IL-12/IL-23 p40 concentration in the observation group were significantly decreased (P<0.05), and the concentrations in the observation group were lower than those in the control group (P<0.05). The expression levels of VDR protein and mRNA in the colon in both groups were all increased (P<0.01), and the expression levels of Reg Ⅳ protein and mRNA and CYP27B1 mRNA were all decreased in the two groups (P<0.05 or P<0.01); the improvements in the observation group were more notable than those in the control group (P<0.05 or P<0.01). Conclusion: Herbal cake-partitioned moxibustion can effectively alleviate abdominal pain and diarrhea in patients with UC, improve depression and anxiety disorders, and regulate the expression of related proteins in the VDR signaling pathway. The mechanism may be related to inhibiting intestinal inflammation by reducing the release of the proinflammatory cytokine IL-12/IL-23 p40.

Objective to establish a combined diagnosis model of scleroderma related genes based on gene expression comprehensive database(GEO)and artificial neural network(ANN)and to evaluate its effect and to predict and analyze targeted traditional Chinese medicine.Methods two scleroderma chips GSE23741 and GSE95065 were obtained from the GEO database as the training group data set.Random forest and lasso regression algorithms were used to screen the key genes of scleroderma and construct the ANN model for the diagnosis of scleroderma.The validation data sets GSE76807,GSE32413 and GSE59785 were used to verify the model,and the area under curve(AUC)analysis was used to evaluate the clinical application value of ANN model.The relative expression of key gene mRNA was verified by RT-qPCR experiment.The CIBERSORT algorithm was used to estimate the bioinformatics association between scleroderma and the screened biomarkers.Finally,the key genes were used to screen the targeted traditional Chinese medicine.Results A total of 167 differential genes were obtained.Furthermore,the five most relevant key genes(SERPINE2,SFRP4,SUGCT,FBLN5,NRXN2)were screened by machine learning,and the artificial neural network diagnosis model was constructed.The model was used to draw the subject operating characteristic(ROC)curves diagnosed by the training group and the verification group,and the AUC value of the training group was 1.000.The AUC of verification group were 0.770,0.795 and 0.872 respectively.The result of RT-qPCR experiment is consistent with that of machine learning algorithm.Immune cell infiltration analysis showed that the relative content of memory CD4+T cells was significantly increased in scleroderma group,while the relative content of γ δ T cells in normal group was significantly increased.Key genes are associated with macrophage M1,T cells,memory activated CD4+T cells,resting mast cells,CD8+T cells and so on.According to the key genes,12 traditional Chinese medicines were screened.Most of the four qi and five flavors belong to warm,cold,flat,sweet,pungent and bitter,and most of them belong to the meridians of liver,spleen and lung.Conclusion the artificial neural network diagnosis model of key genes of scleroderma is constructed,which can be used in clinical diagnosis of scleroderma,and the potential targeted traditional Chinese medicine for the treatment of scleroderma is predicted,which provides a new perspective for exploring the pathogenesis of scleroderma.

Objective:To explore the current situation of the use of assistive devices for mobility in patients with knee osteoarthritis and analyze its influencing factors.Methods:Using the convenient sampling method, patients with knee osteoarthritis who were admitted to the Orthopedics Department of a Class Ⅲ Grade A general public hospital in Zhengzhou from January to July 2019 were selected as the research objects. The general information questionnaire, the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) Scale and other scales were used to conduct surveys. Univariate analysis and binary Logistic regression analysis were used to investigate the influencing factors of the use of assistive devices for mobility in patients with knee osteoarthritis. In this study, a total of 347 questionnaires were distributed and 340 valid questionnaires were returned. The effective recovery rate was 97.98%.Results:The usage rate of assistive devices for mobility in patients with knee osteoarthritis was 26.47% (90/340) , 5.55% (5/90) of the patients were recommended using assistive devices for mobility by medical staff, 2.22% (2/90) of the patients obtained assistive devices for mobility through professional adaptation, and 81.11% (73/90) of the patients did not receive health education on assistive devices for mobility. The total mean score of the QUEST Scale for 90 patients with knee osteoarthritis using assistive devices for mobility was (3.17±0.34) . Binary Logistic regression analysis showed that age, education level, monthly income, pain intensity, the activity of daily living status and social support were influencing factors for the use of assistive devices for mobility in patients with knee osteoarthritis ( P<0.05) . Conclusions:Patients with knee osteoarthritis have a lower usage rate of assistive devices for mobility, receive fewer professional assistive devices for mobility services, and have lower satisfaction with them. There are many factors affecting whether or not to use assistive devices for mobility. Medical staff should pay more attention to and guide the use of assistive devices for mobility for patients with knee osteoarthritis.

Objective:To explore the correlation between periodontitis (PD) and chronic kidney disease (CKD) in adults, as well as the potential mechanisms involved.Methods:Data on PD and CKD from the National Health and Nutrition Examination Survey (NHANES) database between 1999 and 2014 were downloaded. Weighted univariate and multivariate logistic regression analyses were conducted to investigate the risk factors associated with PD and CKD, considering demographic and clinical indicators. Using publicly available genome-wide association study (GWAS) summary datasets for CKD and PD as outcome variables, as well as 731 immune cell phenotypes and 91 inflammatory proteins as exposure factors from the OPEN GWAS database, a two-sample Mendelian randomization (TSMR) analysis was performed using the inverse-variance weighted (IVW) method.Results:Seven demographic indicators including gender, age, race, education level, marital status, income, and health are related to the incidence of CKD and PD. Among them, the elderly (≥60 years old), poverty (poverty-income ratio <1.3), divorce or widowhood, and male ratio in the comorbidity group of CKD and PD [67.12% (833/1 241), 36.83% (457/1 241), 34.41% (427/1 241), and 57.78% (717/1 241) respectively] were significantly higher than those in the control group [23.71% (4 179/17 623), 29.17% (5 141/17 623), 18.16% (3 200/17 623), and 48.73% (8 587/17 623) respectively] (all P<0.001). Those with high educational level (university and above) and self-rated excellent health accounted for a relatively small proportion in the comorbidity group [14.10% (175/1 241) and 8.22% (102/1 241) respectively]. The prevalence of PD increased among individuals with abnormal renal function indices, including glomerular filtration rate, urine protein/creatinine ratio, serum creatinine, serum uric acid, and blood urea nitrogen. Univariate logistic regression analysis showed a positive correlation between the incidence of PD and CKD ( OR=2.14, 95 %CI: 1.90-2.42, P<0.001). Multivariate logistic regression analysis also indicated that PD and CKD were potential risk factors for each other (PD for CKD: OR=1.22, 95 %CI: 1.07-1.40, P=0.004; CKD for PD: OR=1.19, 95 %CI: 1.04-1.37, P=0.012). Furthermore, after adjusting the model based on demographic indicators, there was still a significant correlation between PD and CKD ( P=0.010). Mechanistically, the results of the TSMR analysis support the existence of a common risk factor mediated by immune cells between CKD and PD, namely the expression of CD64 on multiple innate immune cells mediates the occurrence of CKD and PD. The absolute count of CD64 + monocytes is associated with an increased risk for both CKD ( HR=1.11) and PD ( HR=1.07), while same tendency showed in the absolute count of CD64 + neutrophils for CKD ( HR=1.22) and PD ( HR=1.23). Conclusions:There is a positive correlation between CKD and PD, particularly moderate to severe PD, and the shared pathogenesis involves CD64 + monocytes in the circulatory system. Targeted interventions focusing on CD64 molecules or monocyte subsets may be beneficial.

Objective:To analyze the epidemiological characteristics and clinical features of the patients with coronavirus disease 2019 (COVID-19), so as to provide basis for clinical diagnosis.Methods:The epidemiology, clinical symptoms, laboratory and radiologic data of 23 patients with COVID-19 admitted to the Fifth People's Hospital of Xinyang City from January 22nd to January 29th, 2020 were retrospectively analyzed.Results:There was 23 patients with COVID-19, with 15 men and 8 women, and the median age was 46.0 (40.5, 52.0) years old (ranged from 27 years old to 80 years old). Nine patients had basic disease (39.1%), including hypertension (17.4%), cardiovascular diseases (17.4%), diabetes (8.7%), hypothyroidism (4.3%) and past history of tuberculosis (4.3%). All the 23 patients had contact history in Wuhan area or with confirmed cases. Clinical symptoms included fever (100%), cough (69.6%), expectoration (43.5%), myalgia (26.1%), headache (17.4%) and dyspnea (17.4%), and the less common symptom was diarrhea (4.3%). Blood routine tests showed leukocytopenia in 11 patients (47.8%), normal leukocyte counts in 10 patients (43.5%), and leukocytosis in 2 patients (8.7%); lymphopenia was found in 13 patients (56.5%). All 23 patients had different degrees of infective lesions in chest CT, with 7 patients (30.4%) on one side and 16 patients (69.6%) on both sides. There were 19 mild patients, 4 severe patients, and no critical or death case. Complications included acute respiratory distress syndrome (17.4%). No patient was reported with liver, kidney or heart dysfunction or secondary infection.Conclusions:Epidemic history of contact, fever, pneumonia signs of chest CT, normal or decreased count of leukocyte and lymphopenia are the clinical basis for diagnosis of COVID-19. However, at present, the treatment of patients has not been completed, and the effective treatment strategy and final prognosis are unclear.

Objective:To investigate the potential guiding role of fractional flow reserve(FFR) in surgical revascularization by comparing the relationship between coronary fractional flow reserve(FFR) and blood flow pattern status of bypass graft.Methods:A total of 86 patients with coronary artery disease between March 2016 to October 2019 were included in the study, with 59 males and 27 females; the age ranged from 42 to 77 years old, with an average of(58±12) years old. According to the measured FFR value of the left anterior descending artery, they were divided into severe ischemic group(FFR<0.75), boundary group(0.75≤FFR<0.80) and mild ischemic group(FFR≥0.80). Transit time flow meter(TTFM) was used to evaluate the blood flow status of the bridge vessel from the left internal thoracic artery to the left anterior descending coronary artery.Results:Mean graft flow(MGF) was measured at(21.24±5.71)ml/min, (18.25±7.72)ml/min, (16.47±7.83)ml/min in severe ischemic group, boundary group and mild ischemic group. The results of mean pulsatility index(PI) was 2.58±0.96, 3.14±1.19 and 3.53±1.34, the ratio of diastolic flow during the entire graft flow was 0.63±0.10, 0.55±0.11 and 0.53±0.11, patients appeared systolic reverse flow was 2 cases(3.6%), 3 cases(18.8%) and 3 cases (20.0%), respectively. There were statistically significant differences in MGF( P=0.027)、PI( P=0.007)、the ratio of DF( P=0.001) and the quantity of patients appeared systolic reverse flow( P=0.027) between the three groups. Conclusion:Due to increasing severity of coronary artery stenosis, MGF and the ratio of diastolic flow increased, and there appears to be an decreased PI and quantity of patients appeared systolic reverse flow. The chance of bypass graft occlusion may increase for the near and middle term in mild to moderate functional coronary artery stenosis(FFR≥0.75). For patients with severe functional coronary artery stenosis(FFR<0.75), it can obtain satisfactory flow parameters and ideal clinical outcomes.

AIM: To analyze the binding area of atractyloside targeting oncoprotein BORIS to inhibit cancer cell proliferation. METHODS: DNAMAN comparison sequences were used to find the conserved regions of BORIS. Conservative regions were elected and the structure were predicted using SWISS-MODEL. ChemBio3D Ultra was used for minimum structure quantification, and Autodocking for molecular docking. The BORIS of the corresponding segment were overexpressed for verification. RESULTS: BORIS-N end had relatively conserved regions and high-level structures in the biological evolution process. The N-terminal of human-derived BORIS was the main action area we speculated, especially the 70th to 97th amino acids, and the site that binded preferentially to atractyloside after molecular docking was the 96th position (Glutamine), and this area would inhibit cell proliferation. CONCLUSION: BORIS-N terminal and atractyloside have an action area, and this segment has an important effect on cell proliferation, which is of great significance for the future screening of targeted drugs.
