Objective To explore the possible mechanisms of Arsenic Trioxide in treating rheumatoid arthritis(RA)by observing the changes of HE staining and NF-KB expression as well as the apoptosis of syn- oviocytes in adjuvant-induced arthritis rats.Methods After the animal model was set up on Wistar rats sue- cessfully,they were randomly divided into AA model group and arsenic trioxide treatment group.The treat- ment group were injected with 4 mg'kg~(-1)9?d~(-1)arsenic trioxid fluid for 7 days.All of the rats were killed 3 days after the complete of injections.The joint specimens were exposed,fixed,decalcified,wrapped and cut into slices.All slices were examined by HE stain and immunohistological evaluation.Results HE staining showed that when compared with the normal control group,the layers of synoviocytes of the AA group were increased to 6-8,and the arrangement of synoviocytes was disordered and heavy inflammatory cell infiltration were found in the AA group.In the arsenic trioxide treatment group,the layers of synoviocytes increased to 3～4,and medi- um amount of inflammatory cell infiltration were found.The intensity of synovial NF-kB(p65)positive stain in AA model group was significantly higher than that in the normal control group.The synovial expression and ac- tivation of NF-kB in the treatment group were decreased markedly,and did not return to normal level.The average gray scale calculation showed that there were significant differences between the three groups(P

Objective To establish a rabbit model of restenosis and analyze the expressions of VEGFmRNA and TGF-?_1mRNA during the intimal proliferation.We also explored the relationship between VEGFmRNA,TGF-?_1mRNA and restenosis.Methods 40 healthy male New Zealand white rabbits were evenly divided into three injury groups and one control group.Right carotid arteries were injured with PCI balloon in the injury groups.10 rabbits of each injury group were sacrificed on weeks 1,2 and 4 after the injury.VEGFmRNA and TGF-?_1mRNA were examined by in situ hybridization.All the samples were analyzed using a computerized imaging analysis system.Results In the injury groups,neointimal areas were significantly larger than those in control group(P

Objective To compare mobilization effects of endogeneous MSCs in the treatment of ulcerative colitis rats by Shenling Baizhu Powder and Tongxie Yaofang Decoction. Methods Twenty SD male rats were randomly divided into blank group, model group, Shenling Baizhu Powder group and Tongxie Yaofang Decoction group. TNBS/ethanol method was used to build the ulcerative colitis model. Administration groups were given Shenling Baizhu Powder and Tongxie Yaofang Decoction for gavage and model group and blank group were given normal saline for gavage. After gavage, MSCs from peripheral blood and bone marrow were extracted for primary culture. MSCs of bone marrow and peripheral blood were detected by flow cytometry. Results MSCs from bone marrow showed: Compared with the blank group, the percentage of positive cells in the model group decreased (P<0.05); Compared with the model group, the percentage of positive cells in Shenling Baizhu Powder group and Tongxie Yaofang Decoction group increased, and the expression of Shenling Baizhu Powder group was more obvious (P<0.05). MSCs from peripheral blood showed: Compared with the blank group, the percentage of positive cells in the model group increased (P<0.05); Compared with the model group, the percentage of positive cells in Shenling Baizhu Powder group and Tongxie Yaofang Decoction group decreased, and the expression of Shenling Baizhu Powder group was more obvious (P<0.05). Conclusion Shenling Baizhu Powder and Tongxie Yaofang Decoction have the function of promoting the increase of bone marrow-derived MSCs and the reduction of peripheral blood source of MSCs in model rats, and Shenling Baizhu Powder is better than Tongxie Yaofang Decoction.

Objective To investigate the effect of nursing intervention on alleviating patients'psychiatric symptoms after liver transplantation. Methods Patients who suffered from liver transplantation divided into experimental group (n = 50) and control group (n = 162 ) were studied by retrospective contrast analysis. The control group was given the normal nursing, while the experimental group, besides the normal nursing, was administered with psychological intervention and music intervention. Results There was no significant difference between both groups on the anxiety level before the intervention ( P ＞ 0. 05 ); while there was significant difference between both groups after the intervention, the anxiety level of the experimental group was obviously lower than that of the control group ( 3 days before surgery, normal: 70.00% vs 44.44%, χ2 =4.519, P ＜ 0. 05; one week after oporation, normal: 84.00% vs 60.49 %, χ2 = 3. 098, P ＜ 0. 05 ); the anxiety level of the experimental group after the intervention was decreased, compared with that before the intervention ( normal :54.00% vs 84.00%, χ2 = 3. 592, P ＜ 0. 05 ). Conclusions Nursing intervention on patients after liver transplantation could decrease their anxiety and reduce the occurrence of their psychiatric symptoms.

OBJECTIVETo observe the specific clinical efficacy of electroacupuncture at Lingtai (GV 10) and Shendao (GV 11) on premature heartbeat.

METHODSSeventy-two cases of premature heartbeat were randomized into an observation group and a control group.

A 30-year-old female patient with coexisting ankylosing spondylitis and rheumatoid arthritis was diagnosed and treated. The human leukocyte antigen (HLA)-B27 is a predisposing factor of ankylosing spondylitis and HLA-DR4 is a predisposing factor of rheumatoid arthritis. This patient was HLA-B27 and HLA-DR4 positive, and ankylosing spondylitis manifested before rheumatoid arthritis. After disease modifying anti-rheumatic drugs successfully arrested ankylosing spondylitis activity the patient conceived and delivered a healthy baby. One year later, she developed peripheral polyarthritis and was diagnosed with rheumatoid arthritis. We hypothesized that pregnancy may be one of the environmental factors that can activate rheumatoid arthritis, and that disease modifying anti-rheumatic drugs play an important role in keeping the disease under control.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.

De novo variants (DNVs) are one of the most significant contributors to severe earlyonset genetic disorders such as autism spectrum disorder, intellectual disability, and other developmental and neuropsychiatric (DNP) disorders. Presently, a plethora of DNVs have been identified using next-generation sequencing, and many efforts have been made to understand their impact at the gene level. However, there has been little exploration of the effects at the isoform level. The brain contains a high level of alternative splicing and regulation, and exhibits a more divergent splicing program than other tissues. Therefore, it is crucial to explore variants at the transcriptional regulation level to better interpret the mechanisms underlying DNP disorders. To facilitate a better usage and improve the isoform-level interpretation of variants, we developed NeuroPsychiatric Mutation Knowledge Base (PsyMuKB). It contains a comprehensive, carefully curated list of DNVs with transcriptional and translational annotations to enable identification of isoformspecific mutations. PsyMuKB allows a flexible search of genes or variants and provides both table-based descriptions and associated visualizations, such as expression, transcript genomic structures, protein interactions, and the mutation sites mapped on the protein structures. It also provides an easy-to-use web interface, allowing users to rapidly visualize the locations and characteristics of mutations and the expression patterns of the impacted genes and isoforms. PsyMuKB thus constitutes a valuable resource for identifying tissue-specific DNVs for further functional studies of related disorders. PsyMuKB is freely accessible at http://psymukb.net.

Objective:To analyze the risk factors of central venous catheter-related thrombosis (CRT) in critically ill patients and develop the model of a nomogram.Methods:A prospective investigation study was conducted on 385 critically ill patients who received central venous catheters during hospitalization in Hengshui People's Hospital from May 2018 to March 2021. Color Doppler ultrasonography was performed daily after catheterization. Patients were divided into thrombosis group and non-thrombosis group according to whether CRT was formed. The patient's gender, age, body mass index (BMI), acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, complications, existing tumor, D-dimer level on the 3rd day after catheterization, maximum velocity of right internal jugular vein on the 3rd day after catheterization, mechanical ventilation time, and catheter indwelling time were recorded, and the differences of above indexes between the two groups were compared. Multivariate Logistic regression was performed on the influencing factors with statistical differences between the two groups to establish the nomogram prediction. The receiver operator characteristic curve (ROC curve) and calibration curve were used to evaluate the predictive power of the model.Results:The incidence of central venous CRT in critically ill patients was 16.1% (62/385). Compared with non-thrombosis patients, the thrombosis group patients had higher APACHEⅡscore, the proportion of existing tumor, and D-dimer level on the 3rd day after catheterization [APACHEⅡscore: 17 (15, 19) vs. 15 (12, 18), the proportion of existing tumor: 51.6% (32/62) vs. 35.3% (114/323), D-dimer (mg/L): 0.84 (0.64, 0.94) vs. 0.57 (0.44, 0.76), all P < 0.05], the maximum flow rate of right internal jugular vein was slower on the 3rd day after catheterization [cm/s: 14 (13, 15) vs. 16 (14, 18), P < 0.05]. Univariate analysis showed that high APACHEⅡscore, critical patients with existing tumor, high D-dimer level on the 3rd day after catheterization, and slow maximum flow rate of right internal jugular vein on the 3rd day after catheterization were more likely to develop central venous CRT. Further multivariate Logistic regression analysis showed that high APACHEⅡscore, existing tumor, high D-dimer level on the 3rd day after catheterization and slow maximum flow rate of right internal jugular vein on the 3rd day after catheterization were independent risk factors for central venous CRT in critical patients [odds ratio ( OR) and 95% confidence interval (95% CI) were 0.876 (0.801-0.957), 0.482 (0.259-0.895), 0.039 (0.011-0.139), 1.401 (1.218-1.611), and P values were 0.003, 0.021, < 0.001, < 0.001, respectively]. According to the results of multivariate analysis, the prediction model of the nomogram was constructed. The area under ROC curve (AUC) was 0.820, 95% CI was 0.767-0.872, P < 0.001. The calibration curve showed that the prediction probability of central venous CRT nomogram model in critically ill patients had good consistency with the actual occurrence probability. Conclusions:Existing tumor, high APACHEⅡscore, elevated D-dimer on the 3rd day after catheterization, and decreased maximum velocity of right internal jugular vein on the 3rd day after catheterization are independent risk factors for central venous CRT in critical patients. The prediction model based on the proposed model has good clinical efficacy.

Objective To analyze the CD4 +T cells and virus load in HIV/AIDS affected population and to evaluate the HIV/AIDS antiretroviral therapy programs in Henan province.Methods "Henan HIV/AIDS Testing Laboratory Network Database" was used to collect the data on CD4+ T cells and virus load (VL) value and corresponding information in HIV/AIDS population of Henan in 2009. Cross-sectional studies was used to study the constituent ratio of CD4 + T cells and virus load value in individuals who had not received antiretroviral-treated (ART) and had joined first-line ART between the year of 2005 to 2008 among HIV/AIDS population of Henan. Results As to these people living with HIV/AIDS that had not received ART in the first half and the second half year of 2009, the constituent ratio of individuals whose CD4+T cells were less than 200 cells/μl both accounted for more than 20% (χ2=2.059, P=0.151). The constituent ratio of individuals whose CD4+T cells were in 200-350 cells/μl and more than 350 cells/μl increased from 27.61% to 29.41%(χ2=4.636, P=0.031 ) and decreased from 51.49% to 48.60% (χ2=9.767, P=0.002), respectively.Meanwhile, we saw 34.53% and 19.65% of the patients whose virus load was ＞10 000 copy/mland ＞30 000 copy/ml in this population. Patients that joined first-line ART during 2005-2008 showed the following results: the longer of the therapy time, the higher constituent ratio of individuals whose CD4+ T cells were more than 350 cells/μl (χ2= 148.689, P＜0.001) and the lower constituent ratio of individuals of whose CD4+T cells were less than 200 cells/μl (χ2=46.686,P＜0.001).Simultaneously, the lower constituent ratio of individuals whose viral load was less than 500 copy/ml (χ2=9.066, P=0.003) and the higher constituent ratio of individuals whose virus load was more than 10 000 copy/ml (χ2=6.597, P=0.010). Conclusion Significant curative effect had been achieved in AIDS first-line ART of Henan, but along with the increasing treatment time, the risk of treatment failure also increased. Drug resistance test and changing of treatment protocols were needed. To reach better and more efficient effects on therapy, factors as more detections and investments on ART, expanding the scope of treatment etc. were needed on those people living with HIV/AIDS that had not received ART.
