Objective To study the validity of furosemide test for predicting the hematoma enlargement in pa- tients with hypertensive cerebral hemorrhage.Methods Four hundred fifty-one patients with hypertensive cerebral hemorrhage were diagnosed using CT after oneset of the disease and 24 h reexamined 24 h after.The incidence of enlarged hematoma was evaluated by comparison the baseline and 24 h CT scanning.Furosemide(20 mg iv)was ad- ministered and blood pressure was measured 30 min after furosemide.Results The decreasing level of MAP after furosemide was significantly inversely related with incidence rate of hematoma enlargement{ r=-0.94,t=58.4,P 10 mmHg as the cut-off point,with the rate of hematoma enlargement as being 6.4 %,MAP decreased≤10 mmHg was associated with increases in prevalence of hematome to 33.2 %(?~2=51.82, 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.

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

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.

OBJECTIVETo investigate the protective effect of melatonin on residual hair follicle cells of scald rats at early stage.

METHODSEighteen male Sprague-Dawley rats were randomly divided into scald group, treatment group, sham group , with 6 rats in each group. The rats in scald group and treatment group were subjected to 30% TBSA partial thickness scald on the back, and were resuscitated with balanced solution after 1 hour, while those in sham group were immersed in water at 37 degrees C for 25 s to simulate scald, and did not receive fluid replacement. Rats in treatment group were intraperitoneally injected with 10 mg/kg melatonin solution at 1 minute, 8 hours and 12 hours after scald, while those in sham group and scald group were given equal volume of 1% alcohol sodium-isotonic saline instead. Tissue samples were harvested at 6, 12 and 24 post scald hours (PSH) for determination of MDA and GSH levels. Apoptosis of residul hair follicle was detected by TUNEL method and immunohistochemistry of caspase-3.

RESULTSThe level of MDA in scald group at each time point was much higher than that in sham group (P < 0.01) and treatment group (P < 0.05), and it peaked at 12 PSH. The changes in GSH were just opposite to that of MDA. Under fluorescence microscope, the residual hair follicle cells were blue, and the apoptotic cells appeared green. The apoptosis rate in scald group at 6, 12, 24 PSH was obviously higher than that in sham (P < 0.01) and treatment groups (P < 0.05), which was (20.2 +/- 3.4)% vs (4.3 +/- 2.3)% vs (10.9 +/- 3.2)%, (31.2 +/- 3.6)% vs (5.1 +/- 2.5)% vs (19.1 +/- 3.7)%, (22.4 +/- 2.7)% vs (4.1 +/- 2.4)% vs (13.1 +/- 3.4)%, respectively. The score of caspase-3 positive cell in scald group was higher than those in sham group (P < 0.01) and treatment group (P < 0.05).

CONCLUSIONSThere is obvious correlation between oxidative stress and apoptosis rate of hair follicle cells in rats with partial thickness scald. Early administration of melatonin may have anti-apoptosis ability for residual hair follicle cells by attenuation of oxidative stress.

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.

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.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.
