Alemtuzumab (Campath) was successfully injected in 21 kidney transplant patients,7 islet transplant patients and 1 simultaneous kidney and islet transplant patient for either prevention or treatment of graft rejection.Prophylactic administration was successfully completed in all patients without discontinuation.Adverse events were not observed in 11 patients (38%),but hypertension in 18 patients (62%),shivering in 3 patients (10.3%),high fever in 3 patients (10.3%),and bronchospasm in 1 patient (3%),respectively.All complications alleviated after proper therapy.During the prophylactic administration of alemtuzumab,strict,timely and proper ward-management was needed.Care for lung,perineum,skin,diet and psychological nursing were necessary.Neither graft acute rejection nor graft chronic rejection episode occurred in all patients during 6 months to 2 years follow-up.Therefore,long term effects of Alamtuzumab and consequences of lymphocytopenia need further observation.

Objective To evaluate the influence of atopy on exhaled nitric oxide in chronic persistent asthmatic children. Methods A total of 52 chronic persistent asthmatic children who completed FeNO measurements and skin prick testing were enrolled. Patients were divided into non-atopic group and atopic group by skin prick testing results, and subdivided into non-allergic rhinitis and rhinitis group according to whether combined with allergic rhinitis. At the same time 78 healthy children were chosen as control group. Moreover, 32 chronic persistent asthmatic children who completed FeNO measurements twice interval of three months were enrolled. Results The FeNO level was signiifcantly different among the atopic group (n=40), the non-atopic group (n=12) and the control group (H=33.29, P=0.000);The FeNO level was signiifcantly higher in the atopic group than that in the non-atopic group (P<0.05). And the FeNO level were signiifcantly different among the rhinitis group (n=41), the non-rhinitis group (n=11) and the control group (H=30.63, P=0.000). The FeNO level was signiifcantly higher in the rhinitis group than that in the control group (P<0.05), however there were no difference between the rhinitis group and the non-rhinitis group(P>0.05).There were no correlations between FeNO levels of chronic persistent asthmatic children and the wheal diameter of house dust mites or dust mites (r=2.05, P=0.135;r=1.58, P=0.312). Moreover, the FeNO level was signiifcantly lower after 3 months ICS treatment (z=-2.05, P=0.041). Conclusions Atopy had major inlfuence on the FeNO level of chronic persistent asthmatic children, and the FeNO level declined with the theatment of ICS.

Objective To evaluate the efficacy and safety of mesenchymal stem cells(MSCs)in preventing early acute rejection after renal transplantation.Methods Eighty-eight primary cadaveric renal allograft recipients in our department were randomized into two groups treated with bone marrow MSCs (BMSCs group,n =43) or not (control group,n =45).Main immunosuppressive therapy regimen consisted of steroids,tacrolimus or cyclosporine and mycophenolate mofetil in all recipients.Estimated glomerular filtration rate (eGFR) of transplant kidney,incidence of acute reaction (AR),graft survival and incidence of adverse events were recorded within 24 months.Results In BMSCs group,the incidence of AR was 4.7 ％ and 9.3 ％ at 3rd month and 6th month respectively,significantly lower than 20.0 ％ and 26.7 ％ (P＜0.05) in the control group.The eGFR at day 7,14and 30 post-transplantation was significantly higher in the BMSCs group than in the control group (P＜0.01,P＜0.01,P＜0.05 respectively).The incidence of adverse events in the BMSCs group and the control group was 44.2 ％ (19/43) and 66.7 ％ (30/45,P ＜ 0.05) respectively and the rate of infection was 37.2 ％ (16/43) and 33.3 ％ ( 15/46,P ＞ 0.05) respectively within 24 months.Conclusion Induction therapy with autogenous BMSCs appeared to be more effective in the prevention of AR following cadaveric kidney transplantation and was associated with better clinical outcomes as far as early renal graft function without compromising patient safety.

In order to explore the expansive effect of human placental cell-free suspension (HPCFS) on bone marrow hematopoietic stem/progenitor cells, and to compare the effect of HPFCS with some cytokines and their combination, human marrow CFU-GM, CFU-GEMM and BFU-E were assayed in a semisolid methyl cellulose culture system using HPCFS, IL-3, GM-CSF, and IL-3 + IL-6 + GM-CSF + EPO as colony stimulating factors, respectively. The results showed that HPCFS stimulated the growth of CFU-GM, CFU-GEMM and BFU-E and the optimal concentrations for stimulating effect were 200 - 300 micro g protein/L, and the yield of 3 kinds of colony in HPCFS group was higher than that in IL-3, GM-CSF and IL-3 + IL-6 + GM-CSF + EPO groups. The expansive effect of HPCFS on marrow progenitors was superior to IL-3, GM-CSF and IL-3 + IL-6 + GM-CSF + EPO. Human placental cell-free suspension contained a variety of cytokines to stimulate proliferation of hematopoietic stem/progenitor cells, and it could be used as an efficacious and inexpensive agent to expand hematopoietic stem/progenitor cells in vitro.

OBJECTIVETo explore new source of skin for burn wound coverage.

METHODSSplit-thickness consanguineous skin was harvested from New Zealand white rabbit and was soaked in 200 g/L of multi-peptides of Tripterygium wilfordii, 50 g/L of dexamethasonel, on 9 g/L of normal saline solution for 15 - 30 mins, respectively. The consanguineous skin was thereafter grafted onto the whole layer skin defects in filial generation of rabbits with non-consanguineous skin as the control. The survival time and rejection of the grafted skin was observed.

RESULTSThe rejection appeared evidently less intense and survived significantly longer (43 +/- 3.5 days) when the consanguineous skin was pretreated by Tripterygium wilfordii. However the grafted consanguineous skin survived for 30 +/- 2.5 days when it was pretreated by dexamethasone. The grafted skin was quickly rejected and survived only for 11 +/- 1.6 days when the skin was pretreated by normal saline or the skin was non-consanguineous.

CONCLUSIONConsanguineous skin possessed partial compatibility with the recipient due to similar antigen, which was beneficial to the its survival, especially after the skin was pretreated.

With the appearance of direct-acting antivirals (DAAs), breakthroughs have been achieved in the antiviral therapy for hepatitis C and hepatitis C patients can be cured completely. Due to the insidious onset of hepatitis C, most patients do not know their own conditions, and thus expanding diagnosis and treatment through screening is the key to the elimination of hepatitis C. However, hepatitis C virus is distributed widely and unevenly in the world, which results in difficulties in the screening and diagnosis of hepatitis C. This article introduces the current economic research on hepatitis C screening, analyzes the factors affecting the cost-effectiveness of hepatitis C screening, and shares the strategies and advances for hepatitis C elimination in other countries, so as to provide a reference for eliminating hepatitis C in China.

Objective To investigate the effect of intermittent fasting on metabolize and gut microbiota in obese presenium rats fed with high-fat-sugar-diet. Methods We fed the Wistar rats with high-fat and high-sugar diet to induce adiposity, and the rats for intermittent fasting were selected base on their body weight. The rats were subjected to fasting for 72 h every 2 weeks for 18 weeks. OGTT test was performed and fasting blood samples and fecal samples were collected for measurement of TC, TG, HDL-C and LDL-C and sequence analysis of fecal 16S rRNA V4 tags using Illumina. Gut microbial community structure was analyzed with QIIME and LEfSe. Results After the intervention, the body weight of the fasting rats was significantly lower than that in high-fat diet group (P<0.01). OGTT results suggested impairment of sugar tolerance in the fasting group, which showed a significantly larger AUC than compared with the high-fat diet group (P<0.05). Intermittent fasting significantly reduced blood HDL-C and LDL-C levels (P<0.05) and partially restored liver steatosis, and improved the gut microbiota by increasing the abundance of YS2, RF32 and Helicobacteraceae and reducing Lactobacillus, Roseburia, Erysipelotrichaceae and Ralstonia. Bradyrhizobiaceae was found to be positively correlated with CHOL and HDL-C, and RF39 was inversely correlated with the weight of the rats. Conclusion Intermittent fasting can decrease the body weight and blood lipid levels and restore normal gut microbiota but can cause impairment of glucose metabolism in obese presenium rats.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.
