Mesenchymal stem cells (MSC) are non-hematopoietic, multipotent progenitor cells which can be isolated from various human adult tissues. In recent years, MSC have been shown to possess broad immunoregulatory function and tissue regeneration. This review discusses mesenchymal stem cells in hematopoietic stem cell transplantation, including disorders as diverse as acute and chronic graft-versus-host disease, graft failure, pure red cell aplasia, autoimmune thrombocytopenic purpura, hemorrhagic cystitis.

Objective:To investigate the related factors of pancreatic fistula after laparoscopic-assisted distal gastrectomy (LADG).Methods:A retrospective analysis was performed of 189 patients who underwent LADG in Beijing Friendship Hospital, Capital Medical University from June 2017 to March 2018. Twenty-seven patients with postoperative pancreatic fistula and 27 randomly selected normal patients were included in the study. The preoperative characteristics and surgical data of all patients were recorded, including body mass index, visceral fat area, past history, preoperative tumor staging, operation time and bleeding volume, etc. The related factors of postoperative pancreatic fistula were analyzed. Measurement data were expressed as mean±standard deviation ( Mean± SD), and t-test was used for comparison between groups. Chi-square test was used to compare the count data between groups. Results:The patients with high body mass index ( t=3.956, P=0.003), high visceral fat area ( t=6.161, P=0.038), long operation time ( t=2.650, P=0.024), profuse hemorrhage ( t=1.887, P=0.042), complete lymphadenectomy ( t=2.092, P=0.001) were prone to postoperative pancreatic fistula, while there was no significant difference of visceral fat area/total abdominal fat area ( χ2=1.334, P=0.324), preoperative with pulmonary diseases ( χ2=0.750, P=0.379), coronary heart disease ( χ2=0.081, P=0.500), hypertension ( χ2=0.667, P=0.239), diabetes mellitus ( χ2=2.030, P=0.127), chronic kidney disease ( χ2=0.587, P=0.352), tumor stage( χ2=1.388, P=0.500) and other factors between the two groups. Conclusions:Obesity patients and LADG patients with long operation time are more likely to have postoperative pancreatic fistula. Comprehensive preoperative assessment and prudent intraoperative operation may be one of the effective methods to avoid postoperative pancreatic fistula.

Objective To observe the effect of nursing intervention on children with hepatitis C receiving Kurorinone treatment.Methods 98 cases of children patients with hepatitis C admired from February 2008 to May 2010 were randomly divided into the intervention group (50 patients)and the control group(48 patients),all patients were treated with kurorinone for 3 months (one course of treatment),besides the intervention group received additional nursing.The liver function and serum HCV-RNA changes were compared between the two groups.Results Recovery of liver function in the intervention group was significantly better,negative rate of HCV-RNA in the intervention group was significantly higher than that of the control group.Conclusions Nursing intervention can improve treatment effect of kurorinone for children with hepatitis C.

Objective: To investigate the expression of protein MUC1 and MUC2 in intraductal papillary mucinous neoplasms (IPMNs) and its significance. Methods: Immunohistochemical method (En Vision) was used to analyze the expression of protein MUC1 and MUC2 in 18 IPMNs and 9 pancreatic ductal adenocarcinomas. Results: Expression of protein MUC1 was detected in 4 of the 18 (22%) IPMNs (including 1 with pancreatic intraductal papillary-mucinous carcinoma) and all the 9 (100%) the pancreatic ductal adenocarcinomas, with the latter significantly higher than the former(P<0.01). Expression of protein MUC2 was detected in 17 of the 18 (94.4%) IPMNs and in 1 of the 9 (11.1%) pancreatic ductal adenocarcinomas, with the former significantly higher than the latter(P< 0.01). The expression levels of MUC2 were significantly different in IPMNs of different types (IPMA, IPMB, and IPMC, P<0.05). Conclusion: IPMNs have high expression of MUC2 and the expression is associated with the pathological types of IPMN. MUC1 expression may serve as a marker of malignant IPMNs and is worth further studying.

OBJECTIVETo investigate the effects of E 4031, a sodium calcium exchanger (NCX) agonist, on the isolated cardiac function and resting Ca2+ level in myocardial cells from rats with chronic heart failure.

METHODSRats chronic heart failure model was established by abdominal aorta coarctation with; Isolated heart perfusion by Langendorff apparatus was used to detect heart function and the effects of E 4031 on haemodynamic indexes; Myocardial cells of rats in the model group were extracted quickly and co-incubated with calcium fluorescent indicator fluo3/AM and the impact of E 4031 on the fluorescence intensity in myocardial cells were evaluated by confocal microscopy.

RESULTSHeart function of rats in the model group detected by Langendorff perfusion was significantly reduced after 12 weeks, E 4031 at 10 micromol/L could improve their left ventricular developed pressure(LVDP) and systolic / diastolic maximum rate (+/- dp/dtmax). Compared with the control and sham operation groups, the resting Ca2+ fluorescence intensity of the myocardial cells of rats in model group was at a higher level and went through a process of transient rise and drop, then stably remaining at a low level after co-incubated with 10 micromol/L E 4031.

CONCLUSIONE 4031 can improve the isolated heart function of rats with chronic heart failure, which may be associated with its enhancing the activity of NCX in the myocardial cell membrane and stabilizing intracellular Ca2+ level.

The daily intake levels and trend of polychlorinated dibenzo-p-dioxins(PCDDs), polychlorinated dibenzofurans(PCDFs), polychlorinated biphenyls(PCBs) of general population of several developed countries are reviewed. Based on the data of China, PCDD-Fs levels in Chinese human milk and blood were less than that of other countries, in addition, a daily intake of PCDD-Fs for Chinese general population was estimated in the present paper, the tolerable daily intake of Chinese general population was less than that the World Health Organization proposed.

Objective To investigate effects of maintenance hemodialysis with citrate-bicarbonate dialysate on Th17 in peripheral blood of patients with chronic renal failure (CRF). Methods The CRF patients (n=57) with main-tenance hemodialysis for more than three months as well as free-active infection were selected and divided into two groups randomly, which were treated by citrate-bicarbonate dialysate and ordinary carbonate dialysate for mainte-nance dialysis in 12 month, respectively. The levels of interleulin-17 (IL-17) and percentages of Th17 subgroup in peripheral blood were detected by enzyme-linked immunosorbent assay and flow cytometer, respectively. ResultsThe levels of IL-17 and percentages of Th17 subgroup in patients treated with citrate-bicarbonate dialysate for more than six months were significantly lower than those treated with ordinary carbonate dialysate. Moreover, incidences of adverse reactions in group of citrate bicarbonate dialysate were lower than those of common carbonate dialysate group. Conclusion The pro-inflammatory effects of maintenance hemodialysis with citrate-bicarbonate dialysate on the patients are lower than those of ordinary carbonate dialysate. Citrate-bicarbonate dialysate causes the reduction of inflammatory state, and is worthy of being popularized in clinic.
