Progress toward improving management of myelodysplastic syndromes (MDS) occurred every year.This review focused on the new developments of classification,diagnoses,prognostic stratification and therapy on MDS in recent five years.In addiction,a brief introduction of pediatric MDS was presented here.All this were for a better exploration in the future.

Viral infections remain a major cause of morbidity in patients with immunodeficiency,such as recipients of hematopoietic stem cell transplantation (HSCT).Adoptive transfer of donor-derived virusspecific cytotoxic T lymphocytes is a strategy to restore virus-specific immunity to prevent or treat viral diseases and has been tested in the clinical setting for more than 20 years.The 55th ASH annual meeting reported lots of basic and clinical experience about CTL and summarized lots of trails to evaluate it,which will give us some new thought about the antivirus therapy after HSCT.

Objective The aim of this prospective randomized study was to compare the effects of remifentanil (R) and fentanyl (F) given by target-controlled infusion (TCI) on the Cp50 of TCI propofol for loss of consciousness ( LOC ) . Methods Sixty-four ASA 1 or II patients aged 20-55 yr undergoing elective cholecystectomy or mastectomy under general anesthesia were enrolled in this study. Their BMI ranged from 18-30 kg?m-2. The patients were randomly allocated to one of four groups with 16 patients in each group: (1) propofol alone (P), (2) P + remifentanil (Cp = 4 ?g?L-1 ) (R4), (3) P + remifentanil (Cp = 7 ?g?L 1 ) (R7) and (4) P + fentanyl (Cp = 4?g?L-1 ) (F). The patients were unpremeditated. Anesthesia was induced with remifentanil or fentanyl and propofol both given by TCI. The plasma concentration (Cp) of remifentanil and fentanyl were fixed in each group. The Cp50 of propofol for LOC was determined by up-and-down sequential trial. Cp of propofol was set at 1.25, 1.50, 1.80, 2.16, 2.59, 3.11, 3.73 and 4.48 mg?L-1 . If a patient did not go to sleep at a certain Cp of propofol, the next patient was tested at a higher concentration conversely if the patient went to sleep a lower concentration was tested in the next patient. The BIS values and hemodynamic changes were recorded before induction and at LOC (no response to verbal command and loss of eyelash reflex). The TCI pump was controlled by pharmacokinetic models developed by Marsh (propofol) Minto ( remifentanil) and Shafer ( fentanyl) . Results The Cp of propofol for LOC in group P was 3.48 mg ? L-1 , significandy higher than that in group F (2.31 mg ? L -1 ), group R4 (2.11 mg?L-1) and group R7 (1.76mg?L-1 ) (P

Objective To observe the effectiveness of botulinum toxin A (BTXA) in the treatment of small sample patients with acute acquired concomitant esotropia. Design Retrospective case series. Participants 6 patients (3 female and 3 male) with acute acquired concomitant esotropia aged 6 to 34 years. Methods All the patients were received 2.5 units of BTXA injected into the bilateral medial rectus muscles once under electromyographic control. They were performed alter prism-cover test,synoptophore and stereoscopic charts test. Main Outcome Measures The alignment of eyes and binocular vision. Results The follow-up of patients was 4 to 39 months. The pre-injection angle of deviation was 43.3?1.0△; the angle of deviation at the last follow-up was 3.3?8.2△,and 5 patients achieved alignment. In pre-injection,one patient had distance stereopsis,2 patients had near stereopsis with 600 seconds and 40 seconds; after injection,5 patients demonstrated distance and near stereeopsis (3 patients 40 seconds,1 patient 60 seconds,and 1 patient 200 seconds). Conclusion This small sample study shows that BTXA injection is effective alternative in treating acute acquired concomitant esotropia.

Objective To study the expression of TGase3 mRNA in esophageal carcinoma and to investigate it's role and the significance of in the carcinogenesis and progression of esophageal carcinoma.Methods The expression of TGase3 mRNA in 70 ca8es of esophageal carcinoma tissue and 10 cases of normal esophageal tissue were detected by tissue miemarray(TMA)and in situ hybridization(ISH)methods.Results The loss expression rate of TGase3mRNA in esophageal carcinoma tissue was 68.57%(48/70),which was significantly higher than in normal control(P＜0.05).The expression of TGase3 mRNA was no correlation with patients'sex,age,tumor site,lymph node metastasis.But it's significant correlation with clinical stage,histology grade,Pathology grade(P＜0.05).Conclusion There was a high frequency of TGase3 mRNA expression loss in esophageal carcinoma,TGase3 mRNA gene may be involved in carcinogenesis and progression of esophageal carcinoma.

Objective:To study the changes of serum advanced oxidation protein products(AOPP) in patients with diabetic nephropathy(DN) and its correlationship with superoxide dismutase(SOD) and glutathione peroxidase(GPx). Methods: Eighty-five diabetes mellitus (DM) patients were divided into 4 groups: non-DN group(DM, n=25), early-stage DN group(DN3, (n=24), )significant DN group(DN4, n=17) and end-stage DN group(DN5, n=17). The concentration of serum AOPP was measured spectrophotometerically, serum SOD was determined by xanthine oxidase test and GPx by DTNB reaction test. (Results:) The concentrations of AOPP in patients of DN5 group (-[117.8?64.8-] ?mol/L) and DN4 group (-[80.0?23.0-] ?mol/L) were significantly higher than that in DM group (-[58.2?17.7-] ?mol/L,P0.05) and negatively correlated with SOD and GPx(r=-0.217, r=-0.374, P

Objective:To explore the time interval of using electric toothbrush after the adhesion of zinc polycarboxylate cement (ZPC) and PanaviaTM F(PF) respectively.Methods:The facial surfaces of 60 premolars were exposed and embedded in self-curing resin with custom made cylinder-shaped molds.Then the facial surfaces were cut with a diamond saw and polished with waterproof polishing papers to create standardized dentin surfaces.30 co-cr ally test-pieces and 30 zirconia ceramic test-pieces (4.0 mm in diameter and 2.0 mm in height) were adhered on 30 dentin surfaces respectively with ZPC and PF.The samples of each kind were divided into 5 groups (n =6) and brushed with an electronic toothbrush for 30 seconds immedietly (group 1),12 h (group 2),24 h (group 3)and 48 h(group 4) after adhesion,respectively.The samples in group 5 without brush were the controls.Shear bond strength of the samples was measured and the fracture patterns were observed under steriomicroscope.Results:In the ZPC adhered samples the bond strength of group 1,2,3 was lower than that of group 4 and 5 (P ＜ 0.05),group 4 vs group 5,P ＞ 0.05.In the PF adhered simples the bond strenth of group 1 and 2 was lower than that of group 3,4 and 5 (P ＜ 0.05),group 3 or 4 vs group 5,P ＞ 0.05.The fracture patterns were mostly cement cohesive failure.Conclusion:The time intervals of using electric toothbrush after the adhesion of ZPC and PF are 48 h and 24 h respectively

Objective To discuss the efficacy ofcimetidine combined with acyclovir in treatment of children with varicella.Methods 80 cases ofvaricella were randomly divided into two groups.The observation group (40 cases) was treated with cimetidine combined with acyclovir treatment.The control group (40 cases) was given the acyclovir.Observe and record the two groups of children with clinical efficacy,fever time,rash scab,itching disappeared time after treatment,before and after treatment during the HAMA score and the treatment of adverse reactions.The clinical curative effect of cimetidine combined with acyclovir in treatment of children with varicella was evaluated.Results The observation group of total effective rate was 87.5％.The control group of total effective rate was 65％.The total effective rate of observation group was higher than the control group,the difference was statistically significant (P ＜ 0.05).After treatment,the fever time,skin rash,scab time and pruritus disappeared in the observation group were shorter than those in the control group,the difference was statistically significant (P ＜ 0.05).Before treatment,there was no statistical difference in HAMA scores between the two groups.After treatment,the scores of HAMA in the two groups were significantly lower than those in the same group before and after treatment (P ＜ 0.05),and the treatment group was significantly lower than the control group,the difference was statistically significant (P ＜ 0.05).There was no significant difference in adverse reactions between the two groups during the treatment.Conclusion Cimetidine combined with acyclovir have a good therapeutic effect on varicella.They can rapidly improve the clinical symptoms of pediatric varicella,reduce anxiety with high safety.It is worthy of clinical use.
