ABSTRACT
Objective:To preliminary observe the clinical efficacy of vedolizumab (VDZ) in the treatment of active Crohn′s disease (CD).Methods:From March 2021 to October 2022, a total of 22 patients with active CD who received VDZ treatment at Zhongda Hospital, Southeast University were retrospectively enrolled. The general clinical data, laboratory indicators, imaging finding and endoscopic images of the patients were collected. The Crohn′s disease activity index (CDAI), hypersensitive C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), clinical remission rate were evaluated at week 0, 2, 6 and 14 of VDZ administration. Meanwhile, the response rate under endoscopy and remission rate under endoscopy were evaluated after 14 weeks of VDZ administration. The related factors affecting the efficacy of VDZ were further analyzed. Kruskal-Wallis H test and Mann-Whithey U test were used for statistical analysis. The multiple logistic regression analysis was used to find the related factors affecting the clinical remission after VDZ treatment. Results:The CDAI at week 0, 2, 6 and 14 after treatment were 181.01 (160.11, 231.56), 148.05 (134.88, 200.52), 127.46 (91.44, 163.62), and 82.35 (63.50, 121.84), respectively, and the differences were statistically significant ( H=34.23, P<0.001); there were statistically significant differences between week 0 and week 2, 6, 14 after treatment ( U=130.00, 80.00, 33.00; P=0.017, <0.001, and<0.001). The hs-CRP levels were 5.72 mg/L (3.59 mg/L, 11.10 mg/L), 2.86 mg/L (0.86 mg/L, 5.27 mg/L), 1.55 mg/L (0.86 mg/L, 9.89 mg/L) and 2.86 mg/L (0.86 mg/L, 3.12 mg/L), respectively, and the differences were statistically significant ( H=9.69, P=0.021); there were statistically significant differences between week 0 and week 2, 6, 14 after treatment ( U=102.00, 109.00, 98.00; P=0.026, 0.045, and 0.011) .The level of ESR after 14 weeks of VDZ treatment was 8.00 mm/1 h (4.00 mm/1 h, 17.00 mm/1 h), which significantly decreased compared with that before treatment (17.00 mm/1 h(12.25 mm/1 h, 21.75 mm/1 h)), and the difference was statistically significant ( U=132.50, P=0.020). The clinical remission rates at week 2, 6 and 14 after VDZ treatment were 54.5% (12/22), 68.2% (15/22) and 86.4% (21/22), respectively, and the clinical response rates were 18.2% (4/22), 54.5% (12/22) and 95.5% (21/22), respectively. After 14 weeks of VDZ treatment, among 17 patients who underwent endoscopic re-examination, 9 patients achieved response under endoscopy and 3 patients achieved remission under endoscopy. Stenotic type and penetrating type of CD, previous use of glucocorticoids or immunosuppressants were risk factors of no clinical remission after VDZ treatment ( β=-4.586, -5.005 and -3.371; OR=0.010, 0.007 and 0.034; P=0.010, 0.025 and 0.045). While VDZ treatment for 14 weeks was a protective factor ( β=2.475, OR=11.885, P=0.011). Conclusions:VDZ can effectively relieve disease activity in patients with active CD. The disease behavior of CD, previous medication treatment of patients, and the duration of VDZ treatment may be related to the efficacy of VDZ.
ABSTRACT
Objective:To assess the effectiveness and safety of adalimumab in Crohn′s disease (CD) patients.Methods:We retrospectively reviewed the charts of 41 CD patients who received adalimumab in Zhongda Hospital Southeast University from January 2020 to August 2021. General clinical data, laboratory results, endoscopy and radiologic findings were collected, meanwhile, disease activity and safety events were evaluated at baseline and at 12, 24 and 48 weeks of administration. Adalimumab was given subcutaneously once every 2 weeks in doses of 160 mg for the first time, 80 mg for the second time, and 40 mg for each subsequent time.Results:The clinical remission rates at 12, 24, and 48 weeks of treatment were 43.9% (18/41), 60.6% (20/33), 60.9% (14/23), and the clinical response rates were 75.6% (31/41), 69.7% (23/33), and 56.5%( 13/23), respectively. The proportion of endoscopic remission at 12, 24 and 48 weeks were 4/14, 2/6, 1/4 in patients undergoing endoscopy, and 1/14 patients achieved mucosal healing at 24 weeks. Primary nonresponse rate (PNR) was 17.1% (7/41), loss of response (LOR) rate was 14.6% (6/41). The incidence of adverse reactions was 9.8%(4/41).Conclusion:Adalimumab can effectively relieve the clinical symptoms and intestinal disease activities of Crohn′s disease, and deserves to be popularized clinically. Patients with disease course <2 years, first-line biologics, low baseline HBI score, and longer duration of medication may have better results.
ABSTRACT
Objective To study the effect of exosomes ( EXs) released from high expression of miR-132-3p mesenchymal stem cells (MSCs) on hypoxia/reoxygenation (H/R) injured endothelial cell function. Methods MSCs extracted from bone marrow of C57BL/6 mice were cultured primarily. MSCmiR-132-3p was obtained from MSCs infected with lentivirus loaded with miR-132-3p vector. At the same time,MSCNC was obtained by infecting MSCs with control lentivirus loaded with scramble sequence. EXs released from MSCNCand MSCmiR-132-3pwas isolated,and MSC-EXs and MSC-EXsmiR-132-3pwere obtained respectively. The obtained EXs and H/R damaged mouse brain microvascular endothelial cells (bend3) were co-cultured. According to culture conditions,the cells were divided into normal culture group (normal cell culture),H/R group (making a H/R model),MSC-EXs group (MSC-EXs co-culture),MSC-EXsmiR-132-3p group (MSC-EXsmiR-132-3pco-culture), and MSC-EXsmiR-132-3p+ LY294002 group ( before the cells and MSC-EXsmiR-132-3pwere co-cultured,treated by adding phosphatidyl alcohol 3 kinase [ PI3K] signaling pathway blocker LY294002 [20 μmol/L]). Quantitative real-time quantitative polymerase chain reaction was used to detect the expression of miR-132-3p in MSCs,MSC-EXs,and bend3 cells. Angiogenesis kit was used to detect angiogenic ability of bend3 cells,and 3-(4,5-dimethylthiazole-2)-2,5-diphenyltetrazolium bromide (MTT) assay was used to detect the proliferative capacity of bend3 cells. Scratch test was used to detect the migration ability of bend3 cells. hochest33258 staining showed cell apoptosis. Western blot was used to detect the phosphorylation level of protein kinase B ( Akt) . Results Compared with the H/R group, the MSC-EXs treatment group significantly improved the angiogenesis,proliferation,migration abilities, and Akt phosphorylation level of bend 3 cell damage induced by H/R (The H/R group were 3 ± 1,0. 275 ± 0. 020,147 ± 8 μm,and 0. 89 ± 0. 12,respectively;the MSC-EXs treatment group were 8 ± 3,0. 358 ± 0. 030,218 ± 10 μm, and 1. 37 ± 0. 25 μm,respectively;all P<0. 01). Apoptosis was significantly reduced (47 ± 2% vs. 63 ± 2%,all P<0. 01). Compared with the MSC-EXs treatment group,the angiogenesis,proliferation,migration abilities,and Akt phosphorylation level of bend 3 cells in the MSC-EXsmiR-132-3ptreatment group were increased (14 ±3,0. 444 ± 0.050,357±10μm,and1.67±0.23,respectively,all P<0.01).Apoptosis was significantly reduced (34±1%,all P<0. 01) . Compared with the MSC-EXsmiR-132-3ptreatment group, cell proliferation, migration, angiogenesis abilities,and Akt phosphorylation level in the MSC-EXsmiR-132-3p+LY294002 group were significantly reduced (5 ± 2,0. 304 ± 0. 050,175 ± 8 μm and 0. 95 ± 0. 11,respectively,all P<0. 01). Conclusion MSC-EXs with high expression of miR-132-3p may improve many physiological functions of H/R-induced damaged cerebrovascular endothelial cells by activating PI3K/Akt signaling pathway.
ABSTRACT
Objective To investigate the correlation between the characteristics of intracranial lesions and the level of cognitive function in patients with an initial diagnosis of brain metastases.Methods A retrospective analysis was performed in 51 patients with an initial diagnosis of brain metastases who were admitted to The Second Hospital Affiliated to Suzhou University from January 2015 to April 2016.CT and (or) MRI were used to determine the characteristics of intracranial lesions and the Montreal Cognitive Assessment was used to evaluate the cognitive function of patients.Comparison between groups was made by Mann-Whitney U test.The correlation between ranked data was analyzed by Spearman rank correlation test.Results Of the 51 patients with an initial diagnosis of brain metastases,47(92%) had cognitive impairment,including mild cognitive impairment in 31(61%) and dementia in 16(31%).There was no significant difference in level of cognitive function between the patients with involvement of the left hemisphere alone and those with involvement of the right hemisphere alone (P=0.425).The patients with involvement of both hemispheres had a significantly lower level of cognitive function than those with involvement of the left hemisphere alone (P=0.042).The patients with involvement of three or more brain lobes had a significantly lower level of cognitive function than those with involvement of one or two brain lobes (P=0.015,0.024).The intracranial lesion volume and edema volume had no significant effect on the overall cognitive function of patients (P=0.077,0.178).The patients with>3 intracranial lesions had a significantly lower level of cognitive function than those with 1-3 intracranial lesions (P=0.010).Conclusions More than 90% of patients with an initial diagnosis of brain metastases have cognitive impairment.Cognitive impairment is mainly associated with lesion site,involvement of brain lobes,and number of lesions,but not with lesion volume and edema volume.
ABSTRACT
Aim To explore the role of cardiac-specific overexpression of RIP140 in cardiac function and inflammation signaling pathway.Methods Direct intra-myocardial injection of adenovirus vector expressing RIP140 drove transgene expression in heart tissue.RIP140 overexpression was confirmed using immunofluorescence technique in heart.Cardiac function was assessed by echocardiographic and hemodynamic assessment.TNF-α,IL-2 and IL-1β inflammatory cytokines were detected by ELISA,and the protein levels of p65 and IκB-α were measured by Western blot.Results Adenovirus-mediated foreign gene of RIP140 was successfully transferred in cardiac tissue.RIP140 overexpression in heart induced ventricular dilation,decreased left ventricular ejection fraction and cardiac malfunction,as well as increased releases of TNF-α,IL-2 and IL-1β inflammatory cytokines,p65 protein translocation into the nucleus and IκB-α protein degradation in cytoplasm.Conclusion Adenovirus-mediated RIP140 overexpression in cardiac tissue impairs cardiac function,activates NF-κB/p65 inflammatory signaling pathway and induces the release of inflammatory cytokines.
ABSTRACT
Aim The limited transfection efficiency for plasmid in primary neonatal rat cardiomyocytes,which are terminal differentiated cells,and long foreign DNA (the RIP140 gene sequence are as long as 3.5 kb) cause us to choose a better system to study RIP140 gene expression in primary non-replicative cells. Methods Full-length of RIP140 was cloned into pAdTracker-CMV shuttle vector,and then recombined with virus backbone pAdEasy-1 vector in BJ5183 bac-teria.Positive recombinant plasmid was confirmed by sequence analysis and restriction enzyme determina-tion,and then transfected into AD293 cells for amplifi-cation.Titers of virus particles were determined by Tis-sue Culture Infectious Dose 50 (TCID50 )method and cell vitality was analyzed by CCK-8 kit in cardiomyo-cytes.RIP140 gene was identified by Western blot. Results Sequence analysis suggested that full-length RIP140 gene was cloned correctly into AdEasyTM sys-tem.Virus titers of Ad-RIP140 and Ad-GFP were 1011.3 and 1011.7 PFU·mL-1 ,respectively.Cell vitali-ty was not affected when the Multiplicity of Infection (MOI)was lower than 200.Green fluorescent protein (GFP)and Western blot analysis showed RIP140 gene was remarkably increased in cardiomyocytes for 12h in-fection by Ad-RIP140 (P<0.05 ).Conclusion Re-combinant adenovirus containing RIP140 gene was suc-cessfully constructed and effectively expressed in car-diomyocytes.These will be helpful for further research on the function of RIP140 in cardiomyocytes.

ABSTRACT
ObjectiveTo learn the clinical characteristics of concurrent acute-on-chronic liver failure (ACLF) and hepatorenal syndrome (HRS), and to investigate the predictive factors for HRS in patients with ACLF. MethodsA total of 806 patients with ACLF who were admitted to our hospital from January 2012 to May 2014 were selected and divided into two groups according to the incidence of concurrent HRS. Clinical indices and laboratory test results were analyzed in the two groups, and the multivariate logistic regression analysis was used to figure out independent indices for the prediction of HRS in patients with ACLF. A prediction model was established and the receiver operating characteristic curve was drawn to evaluate the accuracy of the prediction model. Comparison of continuous data between the two groups was made by t test, and comparison of categorical data between the two groups was made by χ2 test. ResultsIn all patients with ACLF, 229 had HRS and 577 had no HRS. The univariate logistic regression analysis showed that hepatic encephalopathy, peritonitis, infection, age, cystatin C (Cys-C), serum creatinine (SCr), blood urea nitrogen, albumin, prealbumin, total bilirubin, direct bilirubin, total cholesterol, K+, Na+, phosphorus, Ca2+, prothrombin time, prothrombin activity, international normalized ratio, and hematocrit were significant predictive factors for HRS. The multivariate logistic regression analysis showed that concurrent peritonitis, Cys-C, SCr, and HCO3- were independent predictive factors for HRS in patients with ACLF (OR=3.155, P＜0.01; OR=30.773, P＜0.01; OR=1062, P＜0.01; OR=0.915, P＜0.05). The model was proved of great value in prediction. ConclusionConcurrent peritonitis, Cys-C, SCr, and HCO3- are effective predictive factors for HRS in patients with ACLF.
ABSTRACT
Objective To evaluate the value of diffusion weighted imaging (DWI)in distinguishing the solid solitary pulmonary nodule (SPN).Methods 42 patients with SPN (malignant in 25 and benign in 1 7)who were confirmed by operation,biopsy or follow up after treatment underwent routine chest T1 WI,T2 WI and DWI.The b values were chosen as 300,500,800 and 1 000 s/mm2 ,and the corresponding apparent diffusion coefficient (ADC)values and the signal intensity (SI)were respectively measured.Results The ADC values and SI of benign and malignant SPNs were gradually reduced with increasing b value.The ADC value between benign and malignant SPNs was statistically significant with b value of 500 s/mm2 (P 500 =0.03 <0.05 ),meanwhile the SI was statistically significant with b values from 300 to 1000 s/mm2 (P 300 <0.001,P 500 =0.03 <0.05,P 800 =0.01 <0.05, P 1 000 =0.02<0.05).Conclusion Both SI and ADC value of DWI play important role in distinguishing benign and malignant SPNs, and the diagnostic efficiency of SI is superior to ADC value.

ABSTRACT
Aim To investigate the role of transcrip-tional cofactors receptor interacting protein 140 ( RIP140 ) and peroxisome proliferator-activated recep-tor γ coactivator-1α ( PGC-1α) in the angiotensin Ⅱ( AngⅡ) mediated energy metabolism regulation in cardiomyocytes. Methods RIP140 or PGC-1α was overexpressed via adenovirus vector system. ATP con-tents were detected by luminescence detection assay system. Real-time PCR and Western blot analysis were used to measure the expressions of RIP140 and PGC-1α genes. Results After treated with 100 nmol·L-1 AngⅡfor 36h in neonatal cardiomyocytes, the content of mitochondrial ATP was reduced notably ( P <0. 01). Accordingly, the mRNA and protein levels for RIP140 were increased. However, the mRNA and pro-tein levels of PGC-1α were downregulated markedly. What’ s more,the reduction of ATP induced by AngⅡwas further aggravated by RIP 1 4 0 overexpression , but ameliorated by overexpressing PGC-1α. Conclusion The reduction of ATP mediated by AngⅡis associated with the upregulation of RIP140 , as well as the down-regulation of PGC-1α.

Objective:To explore the utility of psychiatric service of clients having online counseling for anxiety or depression. Methods:The anxiety group was consisted of clients (n=107) who were positive in the Self-rating Anxiety Scale (SAS) online, similarly the depression group was consisted of clients (n=102) with positive results in Self-rating Depression Scale (SDS) online screening. Both groups were investigated with the questionnaires include issues related to the clinical features, diagnostic categories and treatment vs professional advice on clients. Results:In the anxiety group (male 69/female 38), the average age was 28+8, 88(82.2%) with more than 15 years education. In the depression group (male 57 vs. female 45), the average age was 29+8, 81(79.4%) with more than 15 years education. None was illiterate. For the age, sex, education and occupation, there was no significant difference between the two groups. 81(79.4%) clients in the anxiety group and 89(87.2%) clients in the depression group were advised to visit psychiatrists or psychologists. A few were advised to counseling online only and there was no significant difference between the two groups. The main diagnoses were mood disorders, neurosis and psychogenic disorders. Actually, 29(27.1%) in the anxiety group were treated with anxiolitics, 31(30.2%) in the depression group were treated with antidepressants at local clinics. Conclusion:Most of the clients should visit psychiatrists or psychologists, and a few may have their psychological counseling online only. Health education and psychological counseling online may be helpful to improve the rate of diagnosis and treatment of mental disorders in local clinics.
