1.Advances in Study on Cytapheresis in Treatment of Inflammatory Bowel Disease
Chinese Journal of Gastroenterology 2016;21(12):755-758
Inflammatory bowel disease(IBD)is a chronic nonspecific intestinal inflammatory disease and the etiology and pathogenesis are not fully clarified. Studies showed that immune factors play an important role in the pathogenesis of IBD. Cytapheresis(CAP)is a new blood purification method which can selectively filter or adsorb the inflammatory cells and cytokines in systemic circulation. Many studies confirmed that CAP had some therapeutic effect on IBD. This article reviewed the advances in study on CAP in treatment of IBD.

Objective To investigate the efficacy of electromyographic biofeedback therapy (EMGBFT) in treating dysphagia after stroke.Methods Patients diagnosed with dysphagia after stroke were recruited and randomly divided into a control group (n =22),an electrostimulation group (ES,n =25) and an EMGBFT group (n =23).The control group received conventional treatment,while the patients in the other groups additionally received Vitalstim ES or EMGBFT 5 times per week for 3 weeks.Before and after the trial,deglutition function was evaluated through surface electromyography (sEMG) and using a standardized swallowing assessment (SSA).Results After 3 weeks of treatment,the mean sEMG amplitude,deglutition duration and SSA score and improved significantly in comparison to the baseline in all three groups.All were also significantly better in the two treatment groups than in the control group.Importantly,the mean sEMG amplitude,deglutition duration and SSA score were all significantly better in the EMGBFT group than in the ES group.Conclusion EMGBFT can promote better deglutition among patients with dysphagia after stroke more effectively than ES or conventional treatment.

Objective To explore the relationship between syndrome differentiation of diabetic retinopathy (DR) and pattern of visual evoked potential (P-VEP).Methods One hundred and eighty-six eyes from 104 cases of DR were allocated to three groups according to TCM syndrome:qi-yin deficiency (Group A),qi stagnation and blood stasis (Group B) and yin-yang deficiency (Group C).P-VEP induced by various space frequency (0.388?Hz,1.55?Hz) and pictures of various colors (black/white,red/magenta,blue/green) was observed in the three groups and compared with that in the normal control group (Group D).Results One hundred and three eyes in Group A mainly manifested as simple DR,47 eyes in Group B and 36 eyes in Group C mainly manifested as proliferative DR.The latency of P 100 was prolonged and the amplitude was decreassed in all groups of DR,but the latency of P 100 was much prolonged in Group B,the amplitude was much decreased in Group C and the changes were less in Group A.Conclusion P-VEP varies in different TCM syndrome types of DR,and determination of P-VEP under various stimulating conditions may serve as an index of syndrome differentiation of DR.

AIM:To investigate the effect of Sonic Hedgehog ( Shh) signaling blockade on the growth of hema-tocarcinoma cells and underlying mechanisms.METHODS: The expression of Shh signaling molecules in hematocarci-noma cell lines BEL-7402, Huh7 and HepG2 was detected by RT-PCR.The cell viability was detected by MTT assay.The cell cycle and apoptosis were analyzed by flow cytometry.The expression of apoptosis-related proteins was determined by Western blot.RESULTS:Shh signaling molecules were all expressed in BEL-7402, Huh7 and HepG2 cells.The mRNA expression of Patched ( Ptch) , Gli1 and Gli2 was down-regulated by anti-Shh antibody.Blockade of Shh signaling pathway inhibited the proliferation of hepatocarcinoma cells with increasing cells in G0/G1 phase and induced the apoptosis of hepa-tocarcinoma cells.Treatment with anti-Shh antibody down-regulated the protein expression of pro-caspase-3, pro-caspase-8 and pro-caspase-9, while up-regulated the protein levels of cleaved caspase-3, cleaved caspase-8 and cleaved caspase-9 in BEL-7402 cells.CONCLUSION:Blockade of Shh signaling pathway inhibits the growth of hepatocarcinoma at different levels by cell cycle arrest and inducing apoptosis of hematocarcinoma cells.

Objective To observe the expression of Klotho and Na+/Pi cotransporter in high phosphorous-induced rats with 5/6 nephrectomy and its relationship with vascular calcification,as well as to investigate the effect of early intervention by sodium thiosulfate (STS) on the progression of vascular calcification.Methods Either 5/6 nephrectomy (n=21) or sham operation (n=14) was conducted on 35 Sprague Dawley rats,who were then fed with high phosphorus (HP) diet or normal phosphorus (NP) diet for 16 weeks respectively.The rats were divided into 5 groups as follows:(1) remnant kidney rats receiving HP diet (NHP,n=7),(2) remnant kidney rats receiving NP diet (NNP,n=7),(3) sham operation rats receiving NP diet (SNP,n=7),(4) sham operation rats receiving HP diet (SHP,n=7),(5) remnant kidney rats receiving HP diet with STS (THP,n=7).The treatment group was given STS intraperitoneally three times a week for 16 weeks.At the end of the 16th week,rats tail artery blood pressures were tested,serum creatinine (Scr),calcium (Ca2+),phosphorus (P3+),FGF23,iPTH and urine protein were examined.Throacic aorta and kidney were then removed.Vascular calcification was confirmed by Von kossa staining.Klotho and Pit-1 expression in aortas were determined by immunohistochemistry.Renal lesion was determined by PASM-Masson staining.Renal Klotho and NaPi-2a mRNA were determined by real time RT-PCR.Results After 16 weeks,Scr,p3+,FGF23,iPTH,uric protein and blood pressure were significantly higher in NHP than those in SNP rats (all P < 0.05).PASM-Masson staining revealed typical renal pathology of chronic renal failure in NHP group.With the treatment of STS,THP rats showed significant decrease in Scr,t3+,FGF23,iPTH,uric protein and blood pressure by comparison with NHP group (all P < 0.05).Significant vascular calcification was found in NHP group while NNP and SHP group occasionally had vascular calcification;THP group had marked alleviation of vascular calcification.The aorta and renal expression of Klotho decreased remarkably while expression of Pit-1 and NaPi-2a increased significantly in NHP compared with SNP group (all P < 0.05).Accordingly,the aorta and renal expression of Klotho increased and Pit-1 and NaPi-2a decreased significantly in THP compared with NHP group (P < 0.05).Conclusions The early intervention of sodium thiosulfate might regulate Klotho and Na +/Pi cotransporter expression in both aorth and kidney,decreasing serum phosphate,delaying progression of vascular calcification and improving renal function.

Background:Cytapheresis has been used gradually in the treatment of ulcerative colitis( UC),however,its efficacy is still controversial. Aims:To systematically evaluate the efficacy and safety of cytapheresis on UC. Methods:PubMed, Embase,Web of Science,Cochrane Library,CNKI,Wanfang and VIP database were retrieved to collect the randomized controlled trials( RCTs)using cytapheresis for UC. Article selection,data extraction and quality evaluation were conducted independently by two reviewers. Meta-analysis was conducted by using RevMan 5. 3 software. Results:A total of 20 RCTs involving 1 354 UC patients were included. The results of the meta-analysis showed that cytapheresis was superior to conventional therapy or sham procedure in inducing clinical response(RR=1. 36,95% CI:1. 20-1. 55,P﹤0. 000 01), clinical remission(RR=1. 38,95% CI:1. 15-1. 66,P=0. 000 5)and maintenance of remission(RR=2. 92,95% CI:1. 40-6. 08,P=0. 004 ),and no differences in adverse events were found( RR =0. 37,95% CI:0. 11-1. 24,P =0. 110). Conclusions:Cytapheresis has porfound effect on induction of clinical response, clinical remission and maintenance of remission,and is safe as well. However,the conclusion should be verified by more large-scale and multi-center RCTs.
