Objective To investigate the clinical features and treatment of mycoplasma pneumonia in children,to facilitate clinical diagnosis and improve treatment.Methods A retrospective study was performed,and the data of 48 treated cases of mycoplasma pneumonia were analyzed.Results There were 32 males and 16 females, with male to female ratio of 2:1.Less than 1 year age reported 7 cases,accounted for 14%;1 -3 years,19 cases, accounted for 40%;>3-7 years 18 cases,accounted for 38%;and>7 to 10 years,4 cases,accounted for 8%.The youngest patient was 2 months and 10 days old,while the maximum age of patient reported was 9 years.Conclusion Highest prevalence of mycoplasma pneumonia was in 1 to 7 years age group children.Clinical manifestations were fever,cough and wheezing.Use of azithromycin,erythromycin or combination therapy all achieved good outcome.

Cell-based therapy and regenerative medicine offer a paradigm shift in regard to various diseases causing tissue or organ damage.Recently,many authors have focused their atte(n)tion on adipose-derived mesenchymal stem cells (ADMSCs) for their capacity to differentiate into many cell lineages.Acute kidney injury (AKI),as a common emergency,has high morbidity rate and relatively limited treatment.This review will summarize the mechanism of ADMSCs in treatment of acute kidney injury,and hope to lay a foundation for future research.

Recepteur d′origine Nantais(RON),a tyrosine kinase receptor ,is a growth factor receptor belonging to the proto-oncogene met family and has been proved to display abnormal expres?sion in many types of tumors. The RON receptor is activated by binding to the ligand macrophage stim?ulating protein,overexpression of the receptor,variants of the proto-oncogene and by point mutations of the kinase region. The downstream transduction of RON by mitogen-activated protein kinases and phosphoinositide3-kinase signaling pathways can help regulate the proliferation,apoptosis,migration and invasion of tumor cells. A better understanding of the mechanisms and related signaling pathways of RON activation in tumor progress and development will provide more information for the RON-based target therapy.

Objective To investigate the postmortem redistrib ution of morphine in rat model of chronic morphine poisoning. Methods Samples including cardiac blood, liver, heart, kidney, lung and brain tissues were collected in the rats with chronic morphine poisoning at 0～96 h after death, respectively. The morphine amount was measured with solid phase ext raction-gas chromatography. Results The study showed an increase in morphine concentrat ion of postmortem cardiac blood. Significant increase in morphine level was also observed 24～96 h after death in liver, heart and brain tissues, while the kid ney morphine levels decreased at 96 h after death. In the liver there was the g reatest increase (25-fold) in morphine levels 96 h after death. All the sample s showed marked alterations in morphine concentration within 96 h after death c ompared with cardiac blood at time of death. The postmortem morphine levels in b rain were closely related to those in the heart blood. Conclusion The postmortem redistribution of morphine exists in rats with chronic morphine poisoning. The brain tissues may better represent morphine levels in heart blood at the time of death.

The paper designs and implements a digitalized information resources platform for Mongolian medicine based on ASP.NET.The system adopts VS2008 + SQL SERVER2005 and the 3-tier architectural pattern,integrates functional modules such as News Information,Mongolian Medicine,Mongolian Doctors and Q&A,realizes the digitalization of Mongolian medicine resources and establishes a sharing system.Upon testing,the system operates well and achieves the expectations.

This research adopted silt as the sample,and the five highest hydrogen production performing strains contained in the sample were isolated. The strain whose hydrogen production was the highest was identified as Enterobacter cloacae by the analysis of 16S rDNA sequencing and comparison. It is showed by Plackett-Burman Experimental Design that only glucose,citric buffer and reducing agent had significant effects on hydrogen production by Enterobacter cloacae FML-C1. The path of steepest ascent was undertaken to approach the optimal response region of those three factors. Central Composite Design(CCD) and Response Surface Methodology(RSM) were employed to investigate the interaction of the variables and to ascertain the optimal values of the factors,which finally led to the maximum hydrogen production(VH2) . The theoretical optimal medium conditions were:glucose 21.5 g/L,citric buffer 13.6 mL/L,reducing agent10.0 mL/L. The five tentative tests matched this model well. The final VH2 was up to 2347.4 mL/L,which was 127.42% enhanced in comparison to the original. The result shows that PB experiment design and RSM analytical method work well in selecting factors which have significant influences on the hydrogen production and,moreover,achieve the ideal optimal result.

Strains from the cellulose-containing environment were collected. Primary screening(by filter-paper Hutchison solid culture medium and sodium carboxymethylcellulose solid culture medium) and reelection(by filter-paper inorganic salt culture medium and sodium carboxymethylcellulosc Congo red coltnre medium) indicated that five strains obtained were best suited for high performance cellulose degradation. Determination of sodium carboxymethylcellulose activity(CMCA) and filter paper activity(FPA) was accomplished for each of the five. The strongest of the five in CMCA and FPA was applied to the production of cellulose bioethanol by separate hydrolysis and fermentation(SHF) and simultaneous saccharification and fermentation(SSF) respectively.

Objective To investigate the basic biological functions of NKX3.1 with construction of a series of eukaryotic expression vector of NKX3.1 to study its effects on cell cycle and apoptosis.Methods The full-length reading frames (ORF) of NKX3.1 was amplified from normal human prostate tissue with polymerase chain reaction (PCR),the ORF was cloned into T vector,and then NKX3.1 was cloned into eukaryotic expression vector pcDNA3.1 (+) and pcDNA3.1 (-) with this T vector as template.NKX3.1 in pEGFP C1 was transfected into PC3 cell line,and C1 pEFP was taken as control to observe the localization of NKX3.1 in cells.At the same time,NKX3.1 in pcDNA3.1 and pcDNA3.1 were transfected into PC3 cells and the cells were collected after 24 ～48 hours to detect cell cycle and apoptosis by flow cytometry.Results The eukaryotic expression vector of NKX3.1 was constructed successfully.Fluorescent protein was ocated in the nucleus after transfection of NKX3.1 in pEGFP C1,but pEGP C1 was both expressed in nucleus and cytoplasm.There was significant effect on the early apoptosis (P＜0.01),but no effect on the cell cycle (P ＞ 0.05) after transfection of NKX3.1 compared to PC3 cell-transfected with empty vector of pcDNA3.1.Conclusions The result data suggest that NKX3.1 be nuclear protein and have effect on the early apoptosis of PC3 cell line based on the construction of eukaryotic expression vector.

Objective To investigate the effect of the balloon Bionic midwifery on the delivery outcomes and to analyze the clinical value.Methods 1 683 parturients from June 2014 to May 2015 were selected.They were randomly divided into observation group (832 cases,applied balloon Bionic Midwifery) and control group 851 cases.We compared the labor,the postpartum hemorrhage,the outcomes of pregnancy and the rate of survival of neonates of the two groups.Results The first and second stage as well as the total stage of labors of the observation group were lower than the control group (P＜0.01);Also,the rate of cesarean delivery and the hemorrhage together with the asphyxia of neonates were lower than the control group (P＜0.01).However,the rate of vaginal delivery was higher than the control group (P ＜0.05).The differences between them had a great statistical significance.Conclusions The balloon bionic midwifery technology has an advantage in reducing the rate of cesarean delivery and the maternal pain of pregnant women as well as the maternal complications.It is an effective and safe midwifery technology.So it has a great value of spreading in clinical trials.
