BACKGROUND:Stem celltherapy for renal ischemia-reperfusion injury has been the hot topics for many scholars. Its mechanism is very complex, which could not be explained by simple mechanism of stem cells differentiation. It is the result involving a variety of mechanisms. OBJECTIVE:To investigate the influence on immune cells during the bone marrow mesenchymal stem celltherapy for renal ischemia-reperfusion injury, then to preliminary summarize the immune regulation mechanism of bone marrow mesenchymal stem celltherapy for renal ischemia-reperfusion injury. METHODS:First, we established a model of renal ischemia-reperfusion injury in rats and, cultured and purified rat bone marrow mesenchymal stem cells in vitro. Then, the bone marrow mesenchymal stem cells were transplanted into the rat models. Using flow cytometry detection technology, we analyzed the proportion of CD4+CD25+regulatory T cells of rat spleen cells, discussed the effects on immune cells during the bone marrow mesenchymal stem celltherapy for renal ischemia-reperfusion injury, and then transferred the rat’s spleen cells to the nude mice which were subjected to renal renal ischemia-reperfusion injury. Renal function and renal histological changes of nude mice were assessed. RESULTS AND CONCLUSION:The bone marrow mesenchymal stem celltransplantation could significantly inhibit the decrease of CD4+CD25+regulatory T cellof spleen cells in rats with renal ischemia-reperfusion injury. The transplantation of spleen cells from the above-mentioned rats to nude mice could obviously protect nude mice from renal ischemia-reperfusion injury, characterized by lower serum creatinine, blood urea nitrogen and renal tubule pathologic damage score. Therefore, bone marrow mesenchymal stem cells have protective effects on renal ischemia-reperfusion injury by regulating the immune system.

Objective To explore the feasibility of contrast-enhanced ultrasonograhy (CEUS) in preoperative classification of hepatocellular carcinoma (HCC) microvascular morphology.Methods Totally 94 HCC patients who underwent CEUS were analyzed retrospectively. And the offline Time-intensity curve (TIC) were drawn using SonoTumor. The tumor size, alpha fetoprotein (AFP), cirrhosis, Child-Pugh classifi cation, tumor differentiation and TNM stage were statistically analyzed. The intratumoralmicrovessels of HCC in 94 cases were evaluated by CD34 immunohistochemical staining. The relationship between intratumoral microvessel morphology and CEUS parameters were analyzed.Results CD34 immunohistochemical staining showed three distinct microvessel types in 94 cases of HCC: 28 cases of capillary-like type, 14 cases of sinusoid-like type and 52 cases of mixed type. There were no significant differences of clinical data among three microvascular morphology types. The parameters of peak strength (PE), rise time (RT), wash-in rate (WiR), wash-in perfusion index (WiPI), wash-in area under the curve (WiAUC) and mean transit time (MTT) in 28 cases of capillary-like type were (4350.7±2566.0) a.u, (10.7±3.2) s, (717.0±489.9) a.u, (12820.3±8331.6 )a.u, (128 240.8±74 487.1) a.u, (71.9±33.1)s. Those parameters in 14 cases of sinusoid-like type were (2471.6±1107.1) a.u, (16.2±4.2)s, (321.9±171) a.u, (5 561.4±2 938.0) a.u, (86 780.1±47 563.7) a.u, (117.8±69.6)s. And in 52 cases of mixed type they were (3563.2±2343.1) a.u, (14.1±4.8)s, (519.4±403.2) a.u, (9 015.3±6 884.7)a.u, (128 240.8±74 487.1) a.u, (71.9±33.1) s respectively. The CEUS parameters of WiR, WiPI in capillary-like type HCC patients were higher than sinusoid-like type and mixed type HCC patients, while RT was lower than sinusoid-like type and mixed type HCC patients, and the differences were signifi cant (WiR: t=3.87, 3.3, bothP=0.05; WiPI: t=2.96, 2.06, bothP=0.05; RT: t=3.19, 2.34, bothP=0.05). The parameter of PE in capillary-like type HCC patients were signifi cantly higher than that in sinusoid-like type HCC patients (t=2.51,P=0.05). And the parameter of PE in capillary-like type HCC patients was higher than mixed HCC patients, but there was no signifi cant difference. The parameters of PE, WiR and WiPI in mixed type HCC patients were higher than that in sinusoid-like type HCC patients, while RT in mixed type HCC patients were lower than that in sinusoid-like type HCC patients, but there were no signifi cant differences. No signifi cant differences of WiAUC and MTT were observed in HCC patients with different microvascular morphology.Conclusions There were signifi cant differences of CEUS parameters in different microvascular morphology types. And CEUS, as a non-invasive method, can be used for preliminary preoperative prediction of microvascular morphology in HCC patients.

Objective To understand the dynamic of Oncomelania hupensis snail status in Duchang County at north shore of Poyang Lake so as to provide the evidence for formulating the strategy of schistosomiasis control. Methods The data about the snail status in Duchang County from 2005 to 2012 were collected and the change trend of the snail status was analyzed. Re?sults From 2005 to 2012 all the average density of living snails the occurrence rate of frames with living snails the density of infected snails and the area with infected snails showed a trend of sharp decline and stayed at a low level. Compared to 2005 the above 4 indexes in 2008 decreased by 70.06% 90.33% 79.48% and 37.88% respectively and those in 2012 decreased by 99.35% 98.98% 99.33% and 93.84% respectively. The infection rates of snails fluctuated between 0.06%and 0.53%which showed a trend of first decrease and then increase. The snail area maintained at the level of 2 052.5 hm2 since 2007. Con?clusions Most of the indexes of the snail status in Duchang County have decreased to the lowest level in history since 2012 but the snail area is stable and the infection rate of snails shows a fluctuation trend which suggests that the risks of schistosomia?sis transmission still exist and the snail control still should be strengthened.

ObjectiveTo evaluate the primary effect of granulocyte-monocyte colony stimulating factor (GM-CSF) as an immunotherapy option for treatment of residual disease after alloHSCT.Methods Immunotherapy was performed on two patients with blood malignancy to treat residual disease after allo-HSCT. The patient one,who was diagnosed as having MDS-RAEB Ⅱ,showed bone marrow displasis and incomplete chimerism 6 months after unrelated donor HSCT.Immunosuppressive drug was withdrawn without induction of graft-versus-host disease (GVHD).The patient two B-ALL demonstrated a residual disease at molecular level 30 days post-transplantation.Both of them were given GMCSF (300 μg) subcutaneously once every two days for totally three weeks.During the whole period,skin itch and rash,liver function,subgroups of lymphocytes,and MDSCs and DCs in peripheral blood were investigated.Results In case one,grade Ⅰskin acute GVHD (aGVHD) appeared as early as one week after GM-CSF administration,as well as grade Ⅱ (skin and liver) by the end of the third weeks,and GM-CSF injection was withdrawn.One month later since the start of GM-CSF,the patient showed normal bone marrow morphology and full donor type chimerism. Cyclosporine A (CsA), mycophenolate mofetil and methylprednisolone were administered for two weeks to control GVHD.In the other case,grade Ⅰ aGVHD occurred 9 days after GMCSF administration,and whole blood CsA maintained at 0.134-0.472 μmol/L.Prednisone (30mg per day for 5 days) was used to control grade Ⅱ GVHD from the 11th day after GM-CSF,and grade Ⅰ GVHD continued without any intervention.On the 30th day after GM-CSF treatment,bone marrow aspiration showed complete molecular remission.In both of the two cases,no differences in lymphocytic subtypes were revealed before and after GM-CSF administration,while there were trends of increased DC number and decreased MDSCs in peripheral blood.ConclusionThe administration of GM-CSF as an immunotherapy option for blood malignancy may contribute to the clearance of residual disease after Allo-HSCT.

Objective:To analyze the efficacy and cost-effectiveness of probiotics in initial Helicobacter pylori ( H. pylori) eradication therapy. Methods:A total of 267 patients with positive H. pylori infection were randomly assigned to two groups, the control group ( n=133) received a 14-day bismuth agent quadruple therapy and the study group ( n=144) received conventional quadruple therapy plus probiotics from January 2020 to August 2021. Eradication status was assessed 4-12 weeks after treatment. The H.pylori eradication rate, adverse reactions, and cost-effectiveness were compared between the two groups. Results:The H.pylori eradication rate was higher in study group than that in the control group in intention-to-treat (ITT) (80.6%(108/134), 95% CI:73.8%-87.4% vs. 68.4%(91/133), 95% CI:60.4%-76.4%, P=0.022) and per-protocol (83.1%(108/130), 95% CI:76.5%-89.6% vs. 72.2%(91/126), 95% CI:64.3%-80.2%, P=0.037). The incidence of adverse effects in the study group was lower than that in the control group (8.2%(11/134) vs. 18.8%(25/133), χ 2=6.415, P=0.011). Cost-effectiveness analysis showed that compared with the control group, the incremental cost-effectiveness ratio (ICER) of the study group was 1 010.49 yuan. The single factor sensitivity analysis showed that the H.pylori eradication rate of the study group had a greater impact on the results, followed by that of the control group and the cost of bifidobacterium quadruplex viable tablets. The probability sensitivity analysis showed that when the willingness to pay value (WTP) was 2 500 yuan, the probability that the probiotics combined with the bismuth agent quadruple therapy group was more cost-effective than the simple bismuth agent quadruple therapy group was 91.2%. Conclusion:As initial Helicobacter pylori treatment, probiotics combined with the bismuth agent quadruple scheme has a higher eradication rate and a lower incidence of adverse events than the bismuth agent quadruple scheme.
