Objective To study the effects of heat shock treatment of rat bone marrow mesenehymal stem cells(MSCs),the apoptosis ratio of treated-cells under low serum condition and the treated-cells transplantation on left ventricular function in rats with myocardiaIinfarction.Methods MSC8 were heat-treated under 42℃for 30 min,then the heat shock protein-70(HSP-70)was detected bv Western blot.The apoptosis ratio of heat-treated MSCs under low serum condition was tested by Annexin kit.The treated-MSCs labeled with Dil were transplanted into infarcted myocardium and 8 weeks later,the cardiac function of rats in each group was evaluated by echocardiography and cardiac catheterization.Results The immunophenotype of heat-treated MSCs did not vary,Western blot confirmed a higher level expression of HSP-70 in the treated-MSCs group as compared with that in the control group.The early apoptosis ratio was lower in treated-MSCs measured by flow cytometry with annexin staining than that of MSCs when cultured with low serum medium.After 8 weeks,LVEF,LVSP,+dp/dtmax,and-dp/dtmax were significantly higher,and the LVEDP was significantly lowar in heat-treated MSCs transplantation group than that in the control group.Conclusions Heat shock pretreatment of MSCs enhances the tolerance of MSCs to low serum medium,whereas does not lcad to the change of the cell immunophenotype.Transplantation of heattreated MSCs might improve the cardiac function in a rat myocardialinfarction model.

Objective To explore the impact of IL-10 gene polymorphisms on the outcome in HLA matched sibling hematopoietic stem cell transplantation (HSCT).Methods PCR-sequencespecific primer (PCR-SSP) assay was used to analyze the SNP of IL-10 in 77 recipient and donor pairs:-1082 A/G,-819 T/C,-592 C/A.Results IL-10 ATA/ATA (1082,-819,-592) genotype in recipients significantly decreased the incidence of grade Ⅱ-Ⅳ acute graft vursus-host disease (aGVHD) (6.1％ vs.25.0 ％,P＜0.05),reduced 5-year transplant-related mortality (TRM) (10.7 ％± 5.9％ vs.29.7％ ± 5.2％,P＜0.05) and increased disease free survival (DFS) (81.8％ ± 6.7％ vs.56.8％ ± 7.5％,P＜0.05).With regard to the donor genotype,the incidence of grade Ⅱ-Ⅳ aGVHD,extensive chronic GVHD,5-year TRM and DFS had no signicant difference between IL-10 ATA/ATA and non ATA/ATA subgroup.Multivariable analysis also revealed that IL-10 non-ATA/ATA genotype in recipients and high-risk status of disease were two independent risk factors for DFS (HR =2.911,P =0.029; HR =2.686,P =0.027).Conclusion In HLA-matched sibling HSCT,the presence of recipient IL-10 ATA/ATA significantly decreased the incidence of grade Ⅱ-Ⅳ aGVHD and TRM,and increased DFS.

Objective:To explore the feasibility, safety and effectivity of applying transmesenteric vein extrahepatic portosystemic shunt (TEPS) to treat extrahepatic portal vein obstructive disease (EHPVOD).Methods:From December 2020 to April 2021, 12 patients with EHPVOD in the Vascular Surgery Department of Zhengzhou University People′s Hospital were prospectively enrolled in the study. The infra-umbilical median longitudinal minilaparotomy was performed to expose the branch of superior mesenteric vein (SMV). RUPS-100 was introduced into the trunk of SMV. A balloon with a diameter of 20 mm was introduced through right internal jugular vein (RIJV) into inferior vena cava (IVC). Under fluoroscopy, RUPS-100 was used to puncture the balloon in IVC. A stiff guide wire was used to establish the pathway between RIJV and SMV. Finally the portosystemic shunt between IVC and SMV was established with a covered stent-graft. The total operative time, the time of establishing portosystemic shunt alone, the dosage of contrast agent, the preoperative and postoperative pressure of SMV were recorded. Paired t test was used to compare the preoperative and postoperative pressure of SMV. Results:All 12 patients were successfully performed TEPS. The total operative time was (113±32) min, the time of establishing portosystemic shunt alone was (31±5) min, the dosage of contrast agent was (129±48) ml. The postoperative pressure of SMV [(14.3±2.1) mmHg] decreased significantly ( t=20.125, P<0.01) compared to baseline [(27.8±2.7) mmHg]. All portal hypertension symptoms released after the operations.There was 1 case of delayed incision healing, 1 case of bacteremia and 1 case of slight hepatic encephalopathy, but all of them were cured. There was no death case. Postoperative CT showed all portosystemic shunts were patent. Conclusion:TEPS is a new, safe, effective and feasible treatment method for patients of acute and chronic EHPVOD.

OBJECTIVETo clarify the role of endothelial cells (ECs) injury induced by anti-endothelial cell antibody (AECA) in allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSSerum immunoglobulin (IgG) from allo-HSCT recipients were purified and incubated with human umbilical vein vascular endothelium (HUVEC) in vitro, then the functional changes and cell apoptosis were tested.

RESULTSAfter incubation with AECA positive IgG, soluble adhesion molecules significantly elevated in culture supernatant. When concentration of IgG was 160, 320, and 640 μg/ml, concentrations of soluble intercellular adhesion molecule-1 in supernatant were statistically higher in AECA positive groups [(117.10 ± 12.82) vs (78.17 ± 4.90) pg/ml, (151.30 ± 15.35) vs (89.46 ± 6.02) pg/ml, (239.00 ± 32.53) vs (127.80 ± 13.86) pg/ml, P<0.01)]. When concentration of IgG was 40, 80, 160, 320, and 640 μg/ml, concentrations of soluble vascular cell adhesion molecule-1 in supernatant were also statistically higher in AECA positive groups [(38.51 ± 3.76) vs (24.78 ± 2.59) pg/ml, (61.34 ± 6.99) vs (38.20 ± 3.17) pg/ml, (135.60 ± 24.46) vs (63.73 ± 5.08) pg/ml, (221.30 ± 29.40) vs (112.80 ± 8.91) pg/ml, (420.90 ± 31.70) vs (224.40 ± 20.79) pg/ml, P<0.01]. Clotting activity factors also elevated in culture supernatant after incubation with AECA positive IgG. When concentration of IgG was 80, 160, 320, and 640 μg/ml, concentrations of von Willebrand factor were statistically higher in AECA positive groups [(19.51 ± 0.72) vs (17.17 ± 0.60) ng/ml, P=0.0193; (22.97 ± 1.18) vs (18.27 ± 0.61) ng/ml, (26.40 ± 1.54) vs (19.53 ± 0.70) ng/ml, (34.35 ± 1.60) vs (23.81 ± 0.92) ng/ml, P<0.01]. When concentration of IgG was 320 and 640 μg/ml, concentrations of thrombomodulin were statistically higher in AECA positive groups [(57.50 ± 4.50) vs (40.31 ± 4.39) pg/ml, P=0.0132; (59.18 ± 4.11) vs (38.84 ± 5.16) pg/ml, P<0.01]. However, inflammatory factors (IL-1β, IL-6, IL-8 and ANG2) were not statistically different in AECA positive and negative groups (P>0.05). Moreover, IgG from AECA positive samples did not change the proliferation or cell apoptosis.

CONCLUSIONAECA from allo-HSCT recipients dysregulates ECs' function in vitro, but do not induce apoptosis, which is valuable in the pathophysiology of graft-versus-host disease (GVHD) and other complications after allo-HSCT.

OBJECTIVETo explore the impact of interleukin-18 (IL-18) single nucleotide polymorphisms on outcomes of hematologic malignancies with HLA-matched sibling donor hematopoietic stem cell transplantation (allo-HSCT).

METHODSSingle- nucleotide polymorphisms in IL-18 promoter was detected by PCR-sequence-specific primer analysis (PCR-SSP) in 93 recipients and their HLA matched sibling donors. Hematopoietic reconstitution, incidences of graft versus host disease (GVHD) and infections, transplant related mortality (TRM), and disease free survival (DFS) were analyzed.

RESULTSIn comparison with -137 G/C+C/C donor genotype, patients with -137 G/G donor genotype had shorter duration of neutrophil recovery [15(11-23) days vs 17(11-24) days, P=0.01], higher incidence of extensive chronic GVHD (20.6% vs 3.3%, P=0.029), but no difference in the interval of platelet recovery [20(11-46) days vs 20(7-38) days, P=0.844]. The incidence of extensive chronic GVHD in -607 C/C donor genotype (31.6%) was significantly higher than that (10.8%) in C/A + A/A donor genotype (P=0.024). Recipients with -607 C/C genotype also had higher incidence (33.3%) of extensive chronic GVHD than those with C/A+A/A genotype (10.7%, P=0.016). There were no differences in acute GVHD, TRM, and DFS between different genotypes.

CONCLUSIONIL-18 -137 G homozygous genotype in donor facilitated neutrophil reconstitution, but increased the risk of extensive chronic GVHD in patients with allo-HSCT.
