Objective To establish brain hypoxic-ischemic (HI) model using postnatal day 3(P3) SD rats and evaluate the apoptotic neuronal cells in cerebral cortex and neurofunctional development.Methods The P3 rats were randomly divided into HI group (n=35) and control group(n=18).HI was induced in P3 rats with right carotid artery ligation followed by 2.5 h hypoxia in 60 mL?L-1 oxygen at 37 ℃.The injury of neural cells in the cerebral cortex was evaluated by tumor necrosis factor receptor-1(TNF-R1),Caspase-3 immunostaining and Hematoxylin-Eosin (HE) staining in 24 h and 7 d after HI,respectively.Furthermore,the neurofunctional development was evaluated by negative geotaxis reflex and eye opening time.The data were analyzed by SPSS 12.0 software.Results Caspase-3 and TNF-R1 positive cells were abundant in the ipsilateral cortex at 24 h after HI,compared with contralateral part and control group(P

OBJECTIVETo investigate clinical effects of arthroscopy in the treatment of medial meniscal cyst.

METHODSFrom June 2011 to January 2013, 7 patients with medial meniscal cyst were treated with arthroscopy. There were 3 males and 4 females,ranging in age from 27 to 63 years old,with a mean age of (43.93±2.10) years old. The cysts have been discovered for 3 to 30 months,with a mean time of (10.6±1.3) months. All the patients complained of knee pain,especially in the medial joint gap. The Pisani sign, Caklin sign and medial McMurray sign were all positive. Preoperative MRI examination confirmed the diagnosis. Lysholm score changes and clinical efficacy were observed through a six-month follow-up.

RESULTSThe postoperative Lysholm scores were all significantly higher than the preoperative scores. According to Sarimo standard, 6 patients got an excellent result, and 1 good.

CONCLUSIONArthroscopic treatment of medial meniscal cyst has replaced the traditional method, which could retain the normal meniscus as much as possible and repair the meniscus injury simultaneously, as well as get a good curative effect and a good recovery of knee function. This method is worthy of clinical application.

This study was purposed to establish new method for detecting CBFB-MYH11 fusion gene in acute myeloid leukemia (AML) and to evaluate its value in clinical use. All fusion types of reported CBFB-MYH11 fusion gene were defined by search of references and databank, then the primers and probes were designed on this basis, and 3 positive plasmids and negative cell line as control were established. GUSB gene was also amplified as an internal reference. The primer/probe sets were tested with 3 positive plasmids and HL-60 cDNA using quantitative real-time PCR (qPCR) assays, which were then combined as a multiplex qPCR for simultaneous detection of CBFB-MYH11 and GUSB. After optimization, the multiplex qPCR assay demonstrated both high sensitivity (10 copies for all the 3 plasmids) and high specificity. Finally, the multiplex qPCR assay was clinically evaluated with 58 AML patients, and 4 CBFB-MYH11-positive cases (6.9%) were detected, involving A type (3 cases) and J type (1 case). By comparison, the multiplex qPCR assay showed results concordant with sequencing results, and detected one case that was missed by cytogenetic analysis. It is concluded that a novel qPCR method for screening of CBFB-MYH11 fusion gene in AML is established. This method is fast, comprehensive, sensitive, specific, reliable, and should consider to be a robust tool for identification and management of AML patients with CBFB-MYH11 fusion gene.

OBJECTIVENeonatal isoimmune hemolytic disease is still one of the major causes of neonatal hyperbilirubinemia. The infants with severe hemolysis even need phototherapy and exchange transfusion. Early intravenous immunoglobulin infusion may block hemolysis to some extent. This study aimed to investigate the efficacy and safety of immunoglobulin infusion on neonatal isoimmune hemolytic disease by meta analysis.

METHODAll randomized controlled trials on the effect of immunoglobulin infusion on neonatal Rh and ABO incompatible hemolytic disease obtained by searching MEDLINE, Cochrane Library, EMBASE, CNKI and CBM were included. Meta analysis was done by Review Manager 4.2 software.

RESULTSSix trials with totally 456 neonates were included. There were 109 infants with Rh blood group incompatible hemolysis in 4 studies and 347 infants with ABO blood group incompatible hemolysis in 4 studies. There was no significant difference in gestational age, weight and sex between the immunoglobulin infusion and control groups. Compared with those neonates treated with only phototherapy, the infants treated with immunoglobulin and phototherapy had shorter duration of phototherapy (weighted mean difference, WMD -15.42, 95%CI -29.00 to -1.85), less chance to be given exchange transfusion (RR 0.25, 95%CI 0.17 to 0.39) and shorter duration of hospitalization (WMD -25.44, 95%CI -36.93 to -13.94). While intravenous immunoglobulin could not decrease the maximum serum bilirubin level (WMD -29.91, 95%CI -78.24 to 18.42). There was no significant difference in the incidence of late anemia between the two groups. No adverse reaction was found in neonates who received immunoglobulin.

CONCLUSIONSThe results of this meta analysis support that the intravenous immunoglobulin had some therapeutic effect on neonatal isoimmune hemolytic disease. The infants who received immunoglobulin had shorter duration of phototherapy and less chance to be given exchange transfusion. Well designed, double blind and randomized controlled trials with large sample size and long-term follow-up are needed for further evaluation of the efficacy and safety of the immunoglobulin therapy.

Bacillus subtilis B6-1 was used as an original strain for mutagenic treatment and a defined medium was used as the selective medium. A mutant named B. subtilis W003 was isolated after three serial ultraviolet (UV) irradiations and one diethyl sulfate (DES) treatment. The ?-PGA yield on a rotary shaker was enhanced from 10.9 g/L in parental strain to 20.5 g/L in the mutant. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were glucose and (NH4)2SO4 respectively. The optimal fermentation medium was achieved by orthogonal test. In the optimal medium, a ?-PGA yield of 45.3 g/L was obtained after 36 h cultivation.

Aim The relative bioavalability of hydrochloride eperisone granule in 10 healthy volunteers was studied. Methods The time-plasma concentrations of hydrochloride eperisone granule, as test drug, and myonal, as reference drug, were determined by GC-MS, with tolperisone senuing as internal standard.The pharmacokinetic parameters of both reference and test drug were calculated and analyzed with two-one side test and confidential interval test. Results The results showed that the AUC0-8, AUC0-∞, Cmax, Tpeak, t1/2(?) and t1/2(?) were (17.9?1.3)ng?h?ml-1 and(18.6?1.6)ng?h?ml-1, (19.1?1.2)ng?h?ml-1 and (20.2?1.6)ng?h?ml-1, (5.2?0.5)ng?ml-1 and (5.4?0.5) ng?ml-1, (1.05?0.18)h and (1.08?0.23)h, (0.78? 0.13)h and ( 0.82?0.14)h,( 1.8?0.3)h and (1.8?0.3)h, respectively. The relative bioavalability of test drug was (105? 5)%. Conclusion It can be concluded that the test and reference are bioequivalented between individuals, preparations and periods.

The preterm birth has been increasing for the last decade. With the development of neonatal intensive care techniques, the survival rate of preterm infants is increased markedly. However, the brain of preterm infants is so vulnerable to injury that preterm brain injury has become an enormous public health problem. Hypoxia-ischemia and infection/inflammation are two main perinatal risk factors causing premyelinating oligodendrocyte and cortical neuron injury. Encephalopathy of prematurity is characterized by diffuse white matter injury and neuronal/axonal disruption, leading to neurological disabilities such as cognitive impairment and cerebral palsy. The advancement in imaging techniques, especially magnetic resonance imaging, provides more information for preterm brain injury and brain development, which contributes to the diagnosis and follow-up of the preterm infants. This article reviews the progress in encephalopathy of prematurity in order to open a new window to prophylaxis and management of this disease.
