Background Functional magnetic resonance imaging technique based on a manganese (Mn2+) tracer makes labeling the optic nerve in vivo possible.However studies on the optimal concentration and dynamic change after injection of Mn2+ are rare.Objective This study was designed to explore the time- and dose-dependent response for Mn2+-enhanced MRI of visual pathway after intravitreal injection of MnCl2.Methods Different concentrations of MnCl2(0.5,1,2,5,10,15,20,40mmol/L) with a volume of 25μl were intravitreally injected into the left eyes of 48 pigmented rabbits and were randomly divided into eight groups according to the drug concentrations.No reagent reg was injected into the right eyes as controls.MRI was performed at 4,6,8,12,24,48,96 and 168 hours after the administration of MnCl2 to examine the imaging of the optic nerve,chiasma,optic tract,lateral geniculate body and epithalamus.The signal-noise ratio of MRI in visual pathway was calculated and the optimal concentration and best imaging time after injection of MnCl2 were assessed.The use of the animals followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The imaging of the optical nerve in the left eyes was enhanced in comparison with the right eyes 24 hours after injection of 0.5-1 mmol/L MnCl2 with a significant difference in SNR value between these two groups (t=1.17,t=0.95,P>0.05).24 hours after the injection of 2 mmol/L MnCl2 into the left eyes,the SNR value of the optic nerve on the left side was higher than the right side t=8.43,P<0.05),but no image of lateral geniculate body and epithalamus was found in the left side compared to the right side (t=0.04,t=0.22,P>0.05).The strongest imaging signal in optical nerve was seen in 24 hours after the intravitreal injection of 10-40 mmol/L MnCl2 and decayed gradually from 24 to 168 hours with a transportation speed of (3.32±0.19) mm/h in rabbit visual pathway.SNR value of optic nerve showed a positive correlation with the concentrations of MnCl2 with the regression equation Y=77.786+2.467X(F=20.102,P=0.004,R2=0.770).Conclusion Manganese-enhanced MRI is a viable method for temporospatial visualization of optic never in the pigmented rabbits.The image intensity of MRI is associated with the dose of Mn2+.

OBJECTIVETo investigate the characteristics of the tidal breathing pulmonary function in premature infants with different gestational ages.

METHODSA total of 75 premature infants were classified into three groups according to their gestational ages: <32 weeks, 32-33(+6) weeks and 34-36(+6) weeks. Fifty-five full-term infants (39-40 weeks group) were selected as the control group. All infants were given the tidal breathing pulmonary function test at 3-5 days after birth. Moreover, all infants were given the tidal breathing pulmonary function test again at 40 weeks of the corrected gestational age.

RESULTSAt 3-5 days after birth, the three groups of premature infants had significantly lower inspiratory time, time to peak tidal expiratory flow (tPTEF), and ratio of tPTEF to total expiratory time (tPTEF/tE) than the control group (P<0.05). The parameter values of the tidal breathing pulmonary function were lower when the gestational age was lower. Even at 40 weeks of the corrected gestational age, the three groups of premature infants still had significantly lower tPTEF and tPTEF/tE than the control group (P<0.05).

CONCLUSIONSThe tidal breathing pulmonary function of neonates is influenced by the gestational age. The tidal breathing pulmonary function of premature infants is obviously impaired, and the lower the gestational age, the more obvious the impairment.

The effects of two different sample labeling methods on background signal intensities for high-density 60mer oligonucleotide microarray were investigated. Peripheral blood samples from five disease and five control subjects were collected. Total RNA targets from peripheral blood mononuclear cells were extracted and labeled with RD-PCR protocol, which were hybridized to Agilent Human 1B oligonucleotide microarrays in a two-color comparative format. The positive control targets were labeled with the directly incorporated fluorescently-labeled dNTP labeling. The SPSS program was performed to test normality of the dataset, variance homogeneity between the groups, coefficients of variation (CV) and analysis of variance. The results showed that the background signal intensities of Cy3 channel were higher than those of Cy5 channel. The differences of background signal intensities between the RD-PCR approach and the directly incorporated fluorescently-labeled dNTP labeling were extremely significant (P- Cy3

BACKGROUNDAdvances in minimally invasive surgical techniques and neonatal intensive care for neonates have allowed for repair of the neonatal esophageal atresia with tracheoesophageal fistula (EA/TEF) to be approached endoscopically. However, thoracoscopic surgery in children is still performed in only a few centers throughout the world. The aim of this study was to compare the neonatal tolerance to the thoracoscopic repair (TR) and the open repair (OR) and also to discuss anesthetic management in thoracoscopic procedure.

METHODSWe performed a prospective study enrolling newborns diagnosed with EA with distal TEF (type C) receiving the repair surgery between June 2009 and January 2012 in our institution. Data collected included the newborns' gestational age and weight at the time of the operation, operative time, parameters of intraoperative mechanical ventilation, oxygenation, end-tidal carbon dioxide (ETCO2), and analysis of blood gases. Time to extubation and length of stay were also recorded.

RESULTSIntravenous induction with muscle paralysis followed by pressure-control ventilation and tracheal intubation regardless of the position of the fistula can be performed uneventfully in EA/TEF newborns with no additional airway anomalies and large, pericarinal fistulas in our experiences. The thoracoscopic approach appeared to take longer than the open approach. During the procedure of repair, hypercarbia and acidosis developed immediately 1 hour after pneumothorax in both groups. CO2 insufflation did have additional influence on the respiratory function of the newborns in the TR group; values of PaCO2 and ETCO2 were higher in the TR group but the difference did not reach statistical significance. By the end of the procedure, values of PaCO2 and ETCO2 returned to the baseline levels while pH did not, but all parameters made no difference in the two groups. Besides, time to extubation was shorter in the TR group.

CONCLUSIONSThoracoscopic repair of EA/TEF is comparable to the open repair, and is believed to be safe and tolerable in selected patients. A wider range of neonates may be acceptable for thoracoscopic EA/TEF repair with increasing surgical experience.

Objective To obtain the elasticity value of solid breast lesions with supersonic shear wave elastrography (SWE) and apply the binary Logistic regression in order to evaluate the value of SWE in differential diagnosis of benign and malignant breast lesions. Methods SWE quantitative elastography was preformed in 91 breast lesions of 91 patients in Zhenghai Longsai Hospital to obtain the maximum and mean elasticity value (Emax, Emean). And receiver operating characteristic (ROC) curves were used to assess the diagnostic performance. A Logistic regression for the gray scale ultrasound and the elastic modulus was conducted with multiple variables including Emax, Emean, border, echo, form, calcification. Results Pathological examination showed 73 benign lesions and 18 malignant lesions. Emax and Emean of malignant lesions were obviously higher than those of benign lesions [(99.73±41.15) kPa vs (38.59±14.28) kPa, (61.45±24.88) kPa vs (23.46±11.44) kPa, t=-15.05,-14.12, both P=0.000]. The area under the ROC curve of Emax and Emean were 0.932 and 0.915. Taking 63.70 kPa as the threshold of Emax, the sensitivity was 77.8%and the speciifcity was 97.3%. Then taking 44.22 kPa as the threshold of Emean, the sensitivity was 83.3%and the speciifcity was 94.5%. The results of Logistic regression analysis showed:the 3 most effective variables were Emax, border of the lesions and Emean. Conclusions The multivariate analysis model of binary Logistic regression can select the valuable indexes of differential diagnosis of benign and malignant breast lesions. SWE plays an important role in differentiating benign and malignant lesions and it is valuable in clinical practice.

AIM:To investigate the effects of evodiamine on the growth and apoptosis of human hepatocellular carcinoma Huh7 cells,and to illustrate the molecular mechanism that evodiamine enhances antitumor activity of tumors nec -rosis factor-related apoptosis-inducing ligand(TRAIL)in Huh7 cells.METHODS: The cell viability was measured by MTT assay.The cell cycle distribution was analyzed by flow cytometry.The apoptosis rate was determined by TUNEL stai-ning.The protein levels of cell cycle-and apoptosis-related proteins were detected by Western blot analysis.RESULTS:Treatment of Huh7 cells with evodiamine reduced the cell viability(P<0.05).Evodiamine induced cell cycle arrest in G2/M phase by upregulation of p27,cyclin B1, cell division cycle protein 2(Cdc2)and p-Cdc2.Evodiamine triggered apoptosis accompanied by cleavage of caspase-3 and poly(ADP-ribose)polymerase(PARP).Combination of evodiamine with TRAIL significantly reduced the cell viability and increased cleavage of caspase -3 and PARP as compared with the use of each agent alone.Moreover,evodiamine increased the expression of death receptor 5(DR5)in the Huh7 cells.CON-CLUSION:Evodiamine inhibits the cell growth by reducing the cell viability and inducing cell cycle arrest.Evodiamine also triggers cell apoptosis and enhances the sensitivity of Huh 7 cells to TRAIL by upregulating the expression of DR5.

Abstract: Objective To investigate the epidemiological characteristics of pathogens causing bloodstream infection in hematology patients during treatment and to compare the effects of allogeneic hematopoietic stem cell transplantation (HSCT) on them, so as to provide evidence for the diagnosis and treatment of bloodstream infection. Methods A total of 292 cases with bloodstream infection in hematology wards of the PLA General Hospital were collected from 2017 to 2021, which were divided into HSCT group and N-HSCT group according to whether performed HSCT or not. The epidemiological characteristics and influence of pathogenic bacteria in blood stream infection were analyzed and compared between the two groups. Results A total of 362 strains of pathogenic bacteria were collected from 292 cases, including 106 strains in HSCT group (84 cases) and 256 strains in N-HSCT group (208 cases). Bloodstream infections were more common in acute myeloid leukemia (130/392, 44.52%), followed by non-Hodgkin's lymphoma (74/292, 25.34%). The rate of once bloodstream infection in HSCT group was higher than that in N-HSCT Group, but the rate of twice bloodstream infections in N-HSCT group was higher. Gram-negative Bacilli were the most common pathogens (56.08%), with Escherichia coli being absolutely dominant (109/362, 30.11%), followed by Klebsiella pneumoniae (39/362, 10.77%). Coagulase-negative staphylococci (CoNS) (107/362, 29.56%) were the most common Gram-positive cocci. The detection rate of fungi in HSCT group (10/106, 9.43%) was significantly higher than that in N-HSCT Group (3.52%). The drug resistance rate of the common pathogenic bacteria was at a high level, and there was a certain proportion of multi-drug resistant strains (except for Pseudomonas aeruginosa). The resistance rates of CoNS to penicillin, gentamicin, moxifloxacin, clindamycin and rifampicin in HSCT group were higher than those in N-HSCT Group. The resistance rate of Escherichia coli to piperacillin/tazobactam, cephalosporins and etapenem in HSCT group was significantly higher than that in N-HSCT group. Conclusions The pathogens of blood stream infection in hematology patients are complicated and various. It is difficult for clinical diagnosis and treatment to detect multiple infections and multiple pathogens. HSCT patients have a higher risk of fungal bloodstream infection and more multi-drug resistant strains detected. Therefore, the identification of bloodstream infection and multi-drug resistant strains associated with HSCT patients should prompt surveillance.
