Non-myeloablative allogeneic hematopoietic stem cell transplantation has been extensively applied in patients with hematologic malignancies who are ineligible for conventional hematopoietic stem cell transplantation because of age or medical comorbidities. Non-myeloablative regimens lead to an initial state of mixed hematopoietic chimerism which can produce a marked effect of graft versus tumor to treat the diseases. Compared with the conventional hematopoietic stem cell transplantation, non-myeloablative allogeneic hematopoietic stem cell transplantation has a lower transplant-related mortality and incidence rate of graft-versus-host disease. The improvement of non-myeloablative regimens and the prophylaxis of diseases associated with transplantation can improve the therapeutic efficacy. Though many therapies have been introduced and proved to be successful in animal models, we still need to investigate the research trend and the problem on human body.

Objective To investigate the effects of different concentration propofol target controlled infusion on postoperative cognitive function in patients undergoing coronary artery bypass grafting.Methods182 cases with coronary heart disease undergoing off-pump coronary artery bypass grafting were randomly divided into groupA and groupB from January 2014 to December 2016 in our hospital, 91cases in each group.GroupA were given a small dose propofol target controlled infusion anesthesia;groupB were given high dose propofol target controlled infusion anesthesia.The total dose of propofol induction and effect compartment concentration in the two groups were observed, and the Mini Mental State Examination(MMSE) in the two groups was evaluated preoperative, postoperative 24h, 48h, 72h.Concentration of S100β was determined at suture, postoperative 24h, 72h.ResultsThe total dose of propofol induction in the groupA was significantly lower than that in the groupB (P<0.05), effect compartment concentration between the two groups had no statistically significant difference.MMSE scores in the group A at postoperation 24h, 48h, were higher than those in the group B (P<0.05).Concentration of S100β in the group A was lower than those in the group B at suture, postoperative 24h, 72h.MMSE and concentration of S100β in the two groups were not statistically significant at post operation 72h.ConclusionLow dose propofol target controlled infusion can reduce postoperative cognitive dysfunction in patients undergoing coronary artery bypass grafting, which is worthy of clinical application.

Objective To investigate the epidemiology of fungemia and provide evidence for clinical therapy.Methods A retrospective survey was done with the 42 cases of fungemia in our hospital.Results 42 cases of fungemia include 35 cases acute lymphoid leukemia,6 acute myloid leukemia.95.2％ of the fungemia pathogen agent was monilia.8 cases combined with bacterial septicemia,accounting for 19.0％.Drug sensitivity test showed that 2 cases were intermediary to Fluconazole,1 patient was resisdence to Amphotericin B but sensitive to Voriconazole,Itraconazole and fluorocytosine.The main risk factors of fungimia included using wide-spectrum antibiotic,neutophil less than 0.5 × 109/L,central venous indwelling catheter,age and the time of in hospital more than 15 days.Conclusion The effective measure to reduce fungemia morbitity is controlling risk factors.Timely and effectively antifungal therapy is also needed.

Objective To explore the clinical presentation,etiology of sepsis,common positions of in-fection and anti-infectious treatment of pediatric acute leukemia with septicemia resistance to carbapenem. Meth-ods A retrospective chart review of all pediatric acute leukemia with septicemia cases of Beijing Children 's Hospital from December 2011 to September 2015 were analyzed. All cases were selected based on the clinical presentation,at least one Gram-negative bacteria positive result of blood culture and were resistant to carbapen-em. The basic clinical characteristics and the results of blood culture and antimicrobial susceptibilities were ana-lyzed. Results All 45 cases with fever,among them 8 cases under went continued fever,The other 37 cases fe-ver days were ( 6. 1 ± 5. 2 ) d. Twenty-six cases had agranulocytosis. Agranulocytosis time from 2 to 79 days, mean days(15. 2 ± 16. 2)d. Significant difference of fever time between agranulocytosis team and non-agranulo-cytosis team was significant(P=0. 011). Twenty-three cases had infection positions among 45 cases. Lung,di-gestive tract,mouth and crissum were the common positions of infection. The quantum of blood culture samples were 711 parts. There were 162 parts resistant to carbapenems. The primary pathogens were pseudomonas aerugi-nosa,klebsiella pneumoniae, enterobacter cloacae and Escherichia coli. Among those 45 cases, 36 cases were cured,9 cases were ineffective treatment. Conclusion Pseudomonas aeruginosa, klebsiella pneumoniae, enter-robacter cloacae and Escherichia coli accounted for the most of G-bacteria infections resistant to carbapenem in our center. The incidence of septicemia was related to the level of granulocyte and duration of agranulocytosis.

Objective To investigate the alteration in gene expressions of collagen type Ⅰ and type Ⅲ in tissue of obstructive low compliant bladder of rats. Methods Gene expressions of collagen type Ⅰ and type Ⅲ in the rat bladder tissues were evaluated with RT-PCR. Results The gene expressions of collagen type Ⅰ and type Ⅲ in smooth muscle of low compliant bladder were up regulated, but the level of type Ⅲ gene expression was stronger than that of the type I. Conclusion Collagen type Ⅲ and Ⅰ gene expression was upregulated in tissue of obstructive low compliant bladder of rats. Up regulation of collagen gene expression was related to low compliant bladder after obstruction.

Objective To explore the association between three SNPs of IL 10 promoter and childhood systemic lupus erythematosus (SLE).Methods Three SNPs( 1082/ 819/ 592) were genotypes,and evidence for linkage disequilibrium was analyzed using Genehunter 2 0 software.The correlations between symptoms and haplotypes were assessed.Results The results showed that all genotypes and haplotypes in the IL 10 promoter region exhibited to significant association with childhood SLE,and no significant differences in clinical features among childhood SLE with various haplotypes could be demonstrated.But the frequence of haplotype GCC ( 1082 *G 819 *C 592 *C) in children with SLE and their parents was higher than that in adult SLE patients and adult normal controls,and the frequence of ATA in children with SLE was lower than that of adult SLE patients.Conclusion It is concluded that haplotype GCC might have certain relationship with childhood SLE,which deserves further study.

Objective To evaluate the technique and clinical effect of retroperitoneoscopic adrenalectomy for pheochromocytoma.Methods A total of 78 patients received roperitoneoscopic adrenalectomy for pheochromocytoma from March 2006 to June 2008.Retroperitoneal space was enlarged routinely with patient in lateral decubitus position.After adequate retroperitoneal space was created,three relatively bloodless planes were orderly entered for exposure and separation of the adrenal gland and tumor.The first dissection plane was between the psoas and posterior Gerota's fascia.The subsequent dissections were proceeded in the plane between anterior Gerota's fascia and perirenal fat.The third dissection plane was between the adrenal gland and upper pole of kidney.The tumor and parts of adrenal glands were then excised.Results A1l operations were successful.The mean operative time and estimated blood loss were 145?53min and 100?49 ml,with no blood transfusion,and no conversion to open surgery.The mean postoperative analgesic(pethidine) consumption was 57?38mg.Time for oral intake of food and ambulation after operation were 1.6?0.5d and 1.5?0.3d,respectively.The mean postoperative hospital stay was 5.8?1.9d.No major intraoperative complications occurred.Conspicuous fluctuation of blood pressure(≥50mmHg) was observed in 49 patients during operation.56 patients were followed up,and no recurrence or metastasis of the tumor was found during a follow-up period of 12.3?8.7 months in average(range from 2 to 26 months).Conclusions With adequate preparations,retroperitoneoscopic adrenalectomy for pheochromocytoma(≤6cm) is a safe and effective procedure in the hand of an exparienced surgeon since it gives a clear operative field,adequate space for manipulation,distinct anatomic landmark and minimal agitation.

Objective To explore the influence of three SNPs within interlukinc (IL) 10 promoter region on the expression of interlukin 10 mRNA in childhood systemic lupus erythematosus (SLE),then to determine if the SNPs do associate with the pathogenesis of childhood SLE.Methods The levels of IL 10 mRNA were detected in children with SLE and their parents by Taqman PCR,then the correlations between levels of IL 10 mRNA and haplotypes were assessed.Results The results showed that haplotype GCC was associated with higher level of IL 10 mRNA within children with SLE.Conclusion Haplotype GCC is associated with high secretion of IL 10 within childhood SLE,but not operate independently,and maybe it regulates the high secretion of IL 10 with other susceptible genes of SLE.
