Objective To decide the reasonable testing time and to evaluate the distortion product otoacoustic emission(DPOAE) in neonate hearing tests.Methods The neonate were screened by DPOAE within their first 2-5 days.Results The percent of pass of first hearing screening in full-term neonate was 83.1%,and in high risk neonate was 66.7%.Conclusion The best time of first neonate hearing tests is 3 days after their births.In order to make a diagnosis as soon as possible,the hearing tests and follow-up visit after treatment to the high risk neonate should be enhanced.
Objective To investigate the depressant effect and mechanism of trichostatin A(TSA) on proliferation and being induced apoptosis of Histone deacetylase 2(HDAC2) and p53 in human endometrial cancer-1B cell line(HEC-1B).Methods Three levels concentration of TSA(100,200,400 nmol/L) on HEC-1B at different time duration(0,24,48,72 hours) were applied.The expression of HDAC2 in HEC-1B was examined using Western Blot and the data was analyzed with different concentrations of TSA at various treating time duration.The proliferation and apoptotic rates of HEC-1B and the effect of TSA on them were determined using MTT method.At the same testing condition,the expression level of HDAC and p53 in HEC-1B and the effect of TSA were determined using reverse transcription-polymerase chain reaction(RT-PCR).Results TSA has significant inhibition effect on proliferation of HEC-1B,which shows the trend of time duration dependency.With the increasing of TSA dose and time duration,expression of HDAC2 in cancer cells attenuated,but that of p53 increased.Conclusion TSA had the HDAC inhibitor's character,which could inhibit the expression of HDAC2 and promote activation and expression of p53,inhibit proliferation of HEC-1B at the same time.
Objective To discuss the clinical diagnosis method and effect for DVT complicated with pulmonary embolism(PE).Methods The results of diagnosis and treatment in 18 patients who suffered from PE were analyzed retrospectively.Results Fifteen cases were diagnosed PE by CT pulmonary angiography(CTPA),3 cases by nuclein lung scanning.Fifteen cases were placed temporary inferior vena cava filter before anticoagulation and thrombolysis.Urokinase thrombolysis carried out by jugular vein catheter in 11cases.The clinical manifestation were disappeared in all patients.During the following-up of 1 to 62 months,none of the patients recurred.Conclusion CTPA is one of the effective method in diagnosing PE,and that urokinase thrombolysis carried out by jugular vein catheter in PE is safe.

Objective To investigate the values of two-dimensional ultrasonography vs three-dimensional ultrasonography in prenatal diagnosis and fetal anomalies.Methods Prenatal Screening was performed with two-dimensional ultrasonography or three-dimensional ultrasonography in prenatal fetuses of second or third trimester.Results Prenatal screening was performed with two-dimensional ultrasonography or three-dimensional ultrasonography in 1 402 prenatal fetuses in our hospital from May 2008 to March 2009.The results showed that 43 cases(3.07%)of abnormal fetuses were checked out with two-dimensional ultrasonography,and 13 cases(0.92%)were misdiagnosed.With three-dimensional ultrasonography,53 cases(3.78%)of abnormal fetuses were checked out,and 3 cases(0.21%)were misdiagnosed.Conclusion Three-dimensional ultrasonography increases the accurate rate of diagnosing fetal anomaly,and it is an effective prenatal screening method.
Objective To find out the significance of the imbalance between Th17 and CD4+CD25+regulatory T cells(Treg) in patients with chronic heart failure(CHF).Methods Peripheral blood were collected from 71 patients with CHF and 27 healthy controls.The proportion of Th17 and CD4+CD25+ Treg were detected by flow cytometry.Results The proportion of Th17 cells was significantly higher in patients with CHF than that in healthy controls.The proportion of Th17 cells was significantly higher in patients with poor heart function(NYHA Ⅲ-Ⅳ) than that in patients with better heart function(NYHA Ⅰ-Ⅱ).The proportion of CD4+CD25+ Treg was significantly lower in patients with CHF than that in healthy controls.The proportion of CD4+CD25+ Treg was significantly lower in patients with poor heart function(NYHA Ⅲ-Ⅳ) than that in patients with better heart function(NYHA Ⅰ-Ⅱ).Conclusion The proportion of Th17 cells was increased and that of CD4+CD25+Treg decreased in patients with CHF,suggesting that the imbalance between Th17 and CD4+CD25+ Treg may participate in the process of CHF.
Objective To observe the curative effectiveness of thymosin α1 combined with lamivudine in the treatment of chronic hepatitis B. Methods Seventy patients with chronic hepatitis B were randomly divided into treatment group (35 cases) and control group (35 cases). Lamivudine was administrated orally with 100 mg per day for 12 months,as well as other treatments in control group. Treatment group was given with hypodermic injection of thymosin-α1,twice a week for 6 months besides lamivudine treatment. Results On the 6th,12th month after treatment,and 6th month after drug withdrawal,there was no significant difference in the recovery rate of ALT and the clearance rate of HBV-DNA between two,but the clearance rate of HBeAg and HBeAg/HBeAb was significantly different between two groups on the 12th month after tretments and 6th month after drug withdrawal. Conclusion The treatment of thymosin α1 combined with lamivudine for chronic hepatitis B can improve the outcomes.

Objective To investigate the effects of the high expression of Notch signaling pathway in injured spine on the regeneration of the endogenous neural stem cells,and explore its role in the repair of spinal cord injury.Methods The mouse Notch intracellular domain(NICD) plasmids were constructed,and integrated to dextran magnetic nanoparticles(DMN) according to the classical oxidation-reduction method.By using the Alivisatos,and Conwell methods,Nano-based target gene was built,and transfected into rat spinal cord neural stem cells cultured in vitro under the outer magnetic field.Proliferation and apoptosis of cells were detected before and after transfection.Results After the transfection of NICD-DMN into the spinal stem cells,the number of cells was increased significantly,while the apoptosis decreased(P0.05).Conclusion In combination with the outer magnetic field,the specific magnetic NICD can significantly promote the proliferation of endogenous spinal cord stem cells,and inhibit their apoptosis.
Objective To study the effects of C-type natriuretic peptide on the bleomycin (BLM)-induced pulmonary fibrosis in mice. Methods The mice were given an intratracheal injection of BLM or 0.9% saline and assigned to receive continuous infusion of CNP or vehicle,and then divided into three groups:the control group,BLM group,and BLM group treated with CNP. All animals received bronchoalveolar lavage at the 1st,3rd,7th,and 14th days. The BAL fluid was reserved for determination of the number of cells,cell differentiation,and the contents of IL-1β. Fourteen days after BLM injection,the animals were sacrificed,and the change in histomorphology of lung tissues and the content of hydroxyproline in lung homogenate were assessed. Results The pulmonary fibrosis and inflammatory reaction in the BLM mice were more obvious than in the other two groups. CNP could relieve the damage of BLM,and could increase the survival rate. Conclusion CNP can attenuate BLM-induced pulmonary fibrosis by interfering in inflammatory reaction and fibrous degeneration.
