Objective To compare the therapeutic effects of bone marrow stem treatment by different bone marrow mobilization,distinct separation methods or cell suspension density, and to explore the optimal treatment plan of autologous bone marrow stem cell transplantation for decompensated cirrhosis.Methods Twenty three patients with decompensated cirrhosis were studied.100 ~200 mL bone marrow from each patient was harvested in aseptic condition, after isolation and purification by density gradient centrifugation,the stem cells were obtained and transplanted into the liver via hepatic artery.The serum glutamic acid alanine aminotransferase (ALT), albumin (ALB), prothrombin time (PT) and total bilirubin (TBIL) were checked before and l, 2, 3 months after therapy respectively,changes in these indicators of each group were compared by different bone marrow mobilization, distinct separation methods, or cell suspension density.Results After transplantation, levels of albumin increased significantly 1, 2, 3 months after treatment compared with baseline(P<0.05).Patients in bone marrow mobilization group obtained higher stem cell density (P<0.05), which had no significant difference in improving liver function ( ALT, TBIL, ALB, PT) compared with non-bone marrow mobilization group.Patients using the kit significantly improved their albumin (3 months after treatment, P<0.05), which had no significant difference in improving liver function (ALT, TBIL, ALB, PT) compared with using ordinary lymphocyte isolation method group.There was no significant difference in improving liver function ( ALT, TBIL, ALB, PT) between lower magnitude stem cell density group(≤1 ×1010/L) and higher magnitude stem cell density group(1 ×1010/L).Conclusion The treatment for decompensated cirrhosis by transplantation of autologous bone nlarrow stem cells is safe and effective, which can significantly increase the level of albumin in patients with decompensated cirrhosis.Preoperative bone marrow mobilization can increase the rate of stem cells obtained, and the method using the kit improves the leves of protein respectively.They are helpful to improve the efficacy.

OBJECTIVETo assess the role of probiotics in the prevention of neonatal necrotizing enterocolitis (NEC) and to investigate the risk factors for NEC.

METHODSA total of 2528 hospitalized neonates between January 2002 and May 2005 were assigned into either receiving prophylactic use of probiotics bifoco (Prevention group, n=1182) or without probiotics supplementation (Control group, n = 1346). The incidence of NEC was compared between the two groups. The risk factors for NEC were investigated by conditional logistic regression multifactorial analysis.

RESULTSThere were 19 cases of NEC in the Control group (1.41%), but only 6 cases in the Prevention group (0.51%) (P < 0.05). Gestational age (OR = 5.521), hypoxicdouble ended arrowischemic encephalopathy (OR = 3.887), specticemia (OR = 4.854) and critical illness scores (OR = 5.989) were the risk factors for NEC, while the prophylactic use of probiotics was an independent protective factor for NEC (OR = 0.255).

CONCLUSIONSThe prophylactic use of probiotics may reduce the incidence of NEC in neonates.

Objective To study the relationship between Couagen Ⅰ,MMP-2,TIMP-2 gene expression and atrial fibrosis during heart failure(HF)in dog.Methods Fourteen dogs were used and randomized into HF induced by ventricular tachypacing and control group.Burst atrial pacing was used to induce atrial fibrillation(AF).And the mRNA and protein level of collagen Ⅰ,MMP-2 and TIMP-2 were detected by RT-PCR and immunohistochemical technique.Tissue samples were stained with Mallory trichrome.Results Left ventricular ejection fraction (LVEF) decreased from (67.4? 6.0)% to (29.2?7.8)%,the inducible rate of AF(7/7 vs 2/7) and sustained AF(5/7 vs 0/7) increased and duration of AF stabeatrial fibrillation(SAF) [(462.12?181.43)s vs(0.57?0.57) s] prolonged significantly in HF group.Atrial fibrous tissue content and atrial size of HF group were significantly greater than the controls dogs(268.8% in lefe atria and 190.3% in right atria).The mRNA and protein level of collagen Ⅰ(56.2% and 132.2% in lefe atria,37.4% and 78.0% in right atria)and MMP-2 (100.0% and 115.7% in lefe atria,65.7% and 96.8% in right atria) increased evidently in both lefe atria and right atria,TIMP-2 mRNA decreased 46.3% in lefe atria and had no change in right atria and that its protein had no change in both atrium,whereas the ratio of MMP-2/ TIMP-2 of mRNA and protein increased markedly in both lefe atria (285.3% and 148.8%)and right atria (106.1% and 134.7%)of HF group.SAF had a positive correlation with fibrosis and the gene level of collagen Ⅰ in lefe atria,the ratio of MMP-2/TIMP-2 had a positive correlation with fibrosis and collagen Ⅰ gene level in lefe atria during HF.Conclusions The changes of collagen Ⅰ,MMP-2 and TIMP-2 gene expression appear to be a molecular mechanism of AF, and the molecular remodeling of collagen Ⅰ induced by regulation unbalance of MMP-2/TIMP-2 appears to be an important mechanism of atrial fibrosis during HF.

OBJECTIVETo investigate the kinetics of quinoline biodegradation by Burkholderia pickttii, a gram negative rod-shaped aerobe, isolated in our laboratory.

METHODSHPLC (Hewlett-Packard model 5050 with an UV detector) was used for the analysis of quinoline concentration. GC/MS method was used to identify the intermediate metabolites of quinoline degradation.

RESULTSThe biodegradation of quinoline was inhibited by quinoline at a high concentration, and the degradation process could be described by the Haldane model. The kinetic parameters based on Haldane substrate inhibition were evaluated. The values were vmax = 0.44 h(-1), K(S) = 166.7 mg/L, Ki = 650 mg/L, respectively. The quinoline concentration to avoid substrate inhibition was inferred theoretically and determined to be 329 mg/L.

CONCLUSIONThe biodegradation of quinoline conforms to the Haldane inhibition model and the main intermediate metabolite of quinoline biodegradation is 2-hydroxy-quinoline.

OBJECTIVETo investigate the safety and efficacy of prophylactic single antibiotic administration in selective open colorectal surgery.

METHODSTwo hundred and seventy-five patients undergoing selective open colorectal surgery in the Peking Union Medical College Hospital from October 2009 to October 2011 were retrospectively reviewed. Prophylatic single antibiotic administration was used by intravenous infusion 30-60 min before incision. No antibiotics would be given after operation if there was no surgical site infection(SSI). According to the incidence of postoperative SSI, unexplained use of antibiotics, anastomotic leakage and distant-site infection, the clinical outcome was assessed to be prophylactic success, prophylactic failure or distant-site infection, respectively.

RESULTSThere was no intraoperative or postoperative antibiotics related drug anaphylaxis in all the 275 patients. By prophylactic single antibiotic administration, there were prophylactic success in 243 patients(88.4%,243/275), prophylactic failure in 23(8.4%,23/275), distant-site infection in 9(3.3%,9/275). In the 23 patients with failed prophylaxis, there were SSI in 13(4.7%,13/275) patients, postoperative use of broad-spectrum antibiotics for unexplained fever in 2(0.7%,2/275), postoperative anastomotic leakage in 8(3.6%,8/222).

CONCLUSIONProphylactic single antibiotic administration in selective open colorectal surgery is safe and effective.

Ex vivo expanded human bone marrow CD34(+)CD59(+) cells from patients with paroxysmal nocturnal hemoglobinuria (PNH) were transplanted into BALB/c mice in order to investigate their proliferation ability and reconstruction of hemopoiesis, and to lay the groundwork for clinical ABMT/APBSCT in PNH patients. CD34(+)CD59(+) cells were selected from the bone marrow mononuclear cells in PNH patients by using immunomagnetic positive double sorting. Sublethally irradiated BALB/c mice were transplanted with CD34(+)CD59(+) cells enriched from bone narrow of PNH patients. The results showed that human CD45(+) cells were detected in the bone marrow, spleen and peripheral blood of the nude mice by flow cytometry and DNA analysis at 6 weeks post-transplant. Blood routine indicators of nude mice were found to recover to some extent, but did not fully recover. It is concluded that ex vivo expanded bone marrow CD34(+)CD59(+) cells from patients with paroxysmal nocturnal hemoglobinuria could keep their biological characteristics and ability to reconstruct hemopoiesis in irradiated BALB/c mice.

This study was purposed to investigate the expansion and hematopoietic reconstitution capability of CD34(+)CD59(+) cells from patients with paroxysmal nocturnal hemoglobinuria (PNH) by using BALB/c nude mice so as to provide experimental basis for clinical anto-BMT or auto-PBHSCT in patients with PNH. CD34(+)CD59(+) cells were selected from the bone marrow mononuclear cells in normal persons and PNH patients by immunomagnetic positive double sorting and were engrafted sublethally irradiated BALB/c nude mice. The human CD45(+) cells in bone marrow, spleen and peripheral blood of recipient mice were detected by flow cytometry and DNA assay. The results showed that the CD34(+)CD59(+) cells in PNH patient group and normal person group could expanded ex vivo, but ex vivo expansion capability of CD34(+)CD59(+) cells in PNH patient group at day 7 seemed inferior to that in normal control. While CD34(+)CD59(+) cells of PNH patients and normal persons were transfused into recipient mice, the human CD45(+) cells could be detected in bone marrow, spleen and peripheral blood at 6 weeks after transfusion, but there was no statistical difference in counts of CD45 cells between 2 groups. It is concluded that CD34(+)CD59(+) cells from PNH patients may keep characteristics of normal hematopoietic stem cells, and possess ability to expand ex vivo and support hemopoiesis.

OBJECTIVETo study emetic and anti-emetic effects of Rhizoma pinelliae in minks.

METHODThe emetic effect of raw pinellia 2 g kg(-1) (i.g.) was investigated. Three preparations of Rhizoma pinelliae (processed with ginger) were made by ethanol extraction, water extraction and water decoction respectively and their effects on emesis model induced by cisplatin (7.5 mg kg(-1), i.p.) or apomorphine (1.6 mg kg(-1), s.c.) were then studied; the effect of the decoction of ginger-processed Rhizoma pinelliae on rotation-induced emesis model in minks was also observed.

RESULTThe emesis was induced by raw pinellia in minks (P < 0.01); ginger-processed Rhizoma pinelliae, metoclopramide and ondansetron significantly inhibit the emesis induced by cisplatin and apomorphine (P < 0.05).

CONCLUSIONGinger-processed Rhizoma pinelliae exhibits a anti-emetic effect in minks, which may be mediated by inhibiting the function of the vomiting center in central nervous system.
