Objective To evaluate the effect of staged repair for tetralogy of Fallot (TOF) associated with pulmonary artery hy- poplasty.Methods From June 1996 to June 2006,37 patients with TOF were operated on.There were 26 males and 11 females. Their age was 5 months to 17 years(mean 3.6 years) and weight was 4.6~38.0 kg.All patients were diagnosed as TOF with pulmo- nary artery hypoplasty by cardiac catheterization.The mean pre-operative arterial saturation of the patients was (68.2?6.5) %,Mc- Coon ratio was 0.95?0.26 (0.81~1.17) and Nakata index was 82.7?21.6(71.6~97.5) mm~3/m~2.At the time of the first surgi- cal procedure,17 patients underwent central aortopulmonary shunt,13 patients received modified Blalock-Taussig shunt in the left side and 7 patients had modified Blalock-Taussig shunt in the right side.Results There were no easly operative deaths and no late deaths after the first stage repair.Pleural effusion after shunt occurred in 5 patients.The mean arterial saturation was significantly increased to (91.3?10.4) %,P

OBJECTIVETo discuss the protective effect of Mailuoning injection on ischemia/reperfusion (I/R) injury in rats and its mechanism.
METHODHealthy male adult Sprague-Dawley (SD) rats were randomly divided into the sham operation group, the model group, the edaravone (3 mg x kg(-1)) control group, and Mailuoning high, middle and low-dose groups (4, 2, 1 mL x kg(-1)), with 10 rats in each group, and administered with drugs through tail intravenous injection. The middle cerebral artery occlusion (MCAO) was adopted to establish the rat ischemia/reperfusion model. After the ischemia for 2 h and reperfusion for 24 h, the pathological changes in neurovascular units (NVU) of brain tissues at the ischemia side was observed by HE staining. The expressions of glialfibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule 1 (Ibal) were detected by the immunohistochemical method. The expressions of tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) were detected by the western blotting technique.
RESULTMailuoning injection could significantly improve the pathological changes in cortical penumbra brain tissue UVN of (I/R) rats, reduce the number of GFAP and Ibal positive cells, and significantly decrease the expressions of TNF-alpha, IL-1beta, VCAM-1 and ICAM-1 of brain tissues of I/R rats.
CONCLUSIONMailuoning injection shows an obvious protective effect on UVN of I/R rats. Its mechanism may involve the inhibition of the activation of astrocyte and microglia and the secretion and expression of various inflammatory factors.

Objective To establish a novel TRFIA for the measurement of heparanase (HPA) in serum samples,and investigate its clinical application.Methods The micro-pore plate wells were first coated with partially recombinant murine anti-human HPA monoclonal antibody.Biotin-labeled recombinant HPA protein was then used to compete with HPA in serum samples,and the prepared europium (III)-labeled streptavidin (Eu3+-SA) was used as signal readout for establishing the BSA-TRFIA assay.Using this assay,the serum HPA levels in healthy subjects (n=32) and tumor patients (n=54) were measured.The results of BSA-TRFIA were compared with those of ELISA.Two-sample t test (or t' test),and linear correlation analysis were used to analyze the data.Results The sensitivity of BSA-TRFIA for measuring HPA was 0.33 ug/L.The CV values for intra-batch and inter-batch were 5.29% and 7.54%,respectively.The average recovery rate was 105.5%.The standard curve range was 0-1 000 ug/L.The serum HPA level measured by the BSA-TRFIA method in healthy subjects was (2.03_+ 1.47) Iug/L.In tumor patients,the HPA level was significantly higher:(22.13_+7.38) ug/L (t'=19.388,P

A system analysis about the microbial flora of normal and abnormal soybean sauce liquor from the high-salt-level watery state fermentation was made and the dominant bacteria and yeasts were identified.On the other hand,a discussion of effect of temperature on microbial flora was made.The results indicated that there were no obvious differences about the count of aerobe,spore-producing bacteria,enterobacteriaceae,lactic acid bacteria and anaerobe between the normal and abnormal soybean sauce liquor and there were marked differences about the count of yeasts and salt-tolerant bacteria.The predominant yeasts in normal soybean sauce were Torulopsis and Saccharomyces,accounting for 55.9% and 35.3% of the total yeasts separately,and in abnormal soybean sauce were Pichia,candida and Saccharomyces,accounting for 62.8%,17.9% and 9.0% respectively.

Background and purpose:miR-196a2 functions as an oncogene during tumor initiation and pro-gression. The up-regulation promotes tumor cell proliferation, invasion and metastasis. Therefore, it is promising to be an important tumor biomarker. The aim of this study was to investigate whether rs11614913, a gene polymorphic site ofmiR-196a2, is associated with the risk of leukemia.Methods:A case-control analysis was employed. Bone marrow or periph-eral blood was collected from 210 leukemia patients diagnosed from Jan. 2009 to Jul. 2015 in Yantaishan Hospital (case group) as well as 250 healthy people who were physically examined during the same period (control group). Polymerase chain reaction-restriction fragment length polymorphism (PCR-PFLP) was used to detect the genotype of rs11614913. Application test was used to compare the difference in the frequency of each genotype between case group and control group. The odds ratio (OR) of SNP allelic genes was calculated using logistic regression analysis and 95%CI represented the risk of leukemia for each genotype.Results:The distribution differences in the frequency of T/T, C/C, C/T genotype of miR-196a2 rs11614913 between case group and control group were statistically significant (P<0.05). The risk of leukemia for individuals who carried mutant homozygous C/C was 2.661-fold higher than those carried wild-type homozygous T/T, and the difference was statistically significant (P<0.05).Conclusion:ThemiR-196a2 gene polymorphic site rs11614913 was associated with the risk of leukemia. Mutant homozygous C/C or C allelic gene carrying was probably a risk factor for leukemia.

Three osmotolerant yeasts were isolated from three batches of "swollen can" soy sauce produced by a Guangdong condiment plant. These strains grew faster in the media containing 50%~60% glucose or 15% NaCl than in common yeast media. The three yeasts were identified as Pichia etchellsii by using morphological characteristics, physiological and biochemical tests.
