Toxoplasmosis is an infectious disease which affects both human and animals.It distributes all over the world and makes great harm to human beings.In recent years,the morbidity of toxoplasmosis in our country increased because of contacting with pets.Toxoplasmosis has no specific clinical manifestations and responds well to correct treatment.In order to raise clinicians' notice to toxoplasmosis,this article will review the disease from the aspects of etiology,epidemiology,clinical manifestation and experimental diagnosis.

Objective To analyze the distribution ,antibiotic resistance of the pathogens isolated from patients with stroke‐associated pneumonia (SAP) in Department of Respiratory Medicine for better clinical medication .Methods The SAP patients who were treated in the hospital from January 2007 to January 2014 were included in this study .The pathogens were cultured and isolated .Antimicrobial susceptibility of these pathogens was analyzed retrospectively .The multidrug resistant bacteria were identified .Pathogen distribution was compared between the pneumonia associated with cerebral hemorrhage and that associated with cerebral infarction .Results A total of 50 strains of bacterial pathogens were isolated from 40 (12 .3% ) of all the 325 SAP patients ,including 46 strains of gram negative bacilli (92 .0% ) (mainly P . aeruginosa ,15 ;E . coli ,11 ;A . baumannii ,5 ;and S .marcescens ,5) and 4 (8 .0% ) strains of S .aureus ,all resistant to methicillin (MRSA) .P .aeruginosa isolates were not resistant to imipenem or aminoglycoside antibiotic ,but highly resistant to the third generation cephalosporins . E .coli strains were not resistant to imipenem or piperacillin‐tazobactam .A .baumannii strains were all multi‐drug resistant . At least 40% of these strains were resistant to imipenem ,aminoglycosides or the fourth generation cephalosporins .All the 4 were gram negative bacilli in Department of Respiratory Medicine ,mainly non‐fermentative bacteria and Enterobacteriaceae , most of which were multi‐drug resistant .MRSA is becoming an important pathogenic bacteria .The prevalence of E .coli is significantly different between the pneumonia associated with cerebral hemorrhage and that associated with cerebral infarction .

Objective To investigate the effect of MT-1 and MT-2 in liver damage in chronic inorganic arsenate exposure mice and to explore the mechanism of arsenic-induced liver damage. Methods The male Kunming mice were randomly divided into control and exposed groups. The control group was given ordinary feed and tap water. The exposed group was given ordinary feed and 300 mg/L of sodium arsenite solution by drinking water. After 10 months of treatment, the activity of serum alanine aminotransferase (ALT), aspartate aminotransferase(AST) and globulin (Glb) content were determined. The total RNA was extracted by the TRIzol-phenol-chlorofor-method from the liver tissue. The quantity of the RNA was determined by spectrophotometry and its purity was judged at a ratio of A260/A280. Then real-time PCR(RT-PCR) was used to measure the mRNA expression of MT-1 and MT-2. Results Compared with the control group, serum ALT, AST activity and Glb content were higher and the MT-1 and MT-2 mRNA content was lower in the exposed group (P

Parkinson's disease(PD) is a common neurodegenerative disorder with no effective protective treatment,characterized by a massive degeneration of dopaminergic neurons in the substantia nigra(SNpc) and the subsequent loss of their projecting nerve fibers in the striatum.The major neurochemical manifestation of this disorder is the loss of the neurotransmitter dopamine(DA) in the striatum as a result of the progressive degeneration of the dopaminergic neurons in the substantia nigra.There have been significant progresses in recent years reporting on the use of mesenchymal stem cells(MSCs)in gene therapy,with specific application towards PD.MSCs,a kind of multipotent adult progenitor cells,are considered as a useful vehicle for cell and gene therapy because of their multiple differentiation potentiality and self-transplantation.The present study was focused on treating rat model of PD using human tyrosine hydroxylase gene(hTH),human aromatic L-amino acid decarboxylase gene(hAADC) and human GT Pcyclohydrolase I gene(hGCH-I) engineered MSCs,in order to provide a better understanding about the application of these cells in the therapeutic benifit of PD.The gene of hTH,hAADC and hGCH-I were introduced via recombinant adeno-associated virus(rAAV) infection into the MSCs in vitro.The genetically modified MSCs expressing hTH,hAADC and hGCH-I were transplanted into the striatum of PD rat models.The behavior,the nigra-striatal level of DA and its metabolite were detected.The results of present study were shown as follows:hTH,hAADC,hGCH-I and LacZ gene were transfected into MSCs with adeno-associated virus vectors.The HEK293 packaging cells(ATCC) were transfected with the plasmids of pAAV-hTH,pAAV-hAADC,pAAV-hGCH-I,pAAV-LacZ,pAAV-RC,pHelper by using calcium phosphate precipitation.Titer was detected using HT1080 cells.Viral particles were collected and used to infect MSCs.The purified modified MSCs expressing the three kinds of genes were selected separately and were grafted in the striatum of the PD model rats in the lesion side.The MSCs genetically modified suvived well 12 weeks after transplantation.The improvements of the behavior were observed every week after transplantation.Compared with the control group,the rounds of asymmetric rotation after apomorphine administration decreased in the groups double or triple genes engineered MSCs grafted(p

ObjectiveTo investigate the age distribution of serum prostate specific antigen (PSA) and explore its correlation with fasting blood glucose(FBG)and lipid in the male elderly.MethodsThe levels of FBG,triglyceride (TG),low-density lipoprotein (LDL-C),high density lipoprotein (HDL-C) and PSA were reviewed in 2903 elderly men (aged ≥ 60 years) in our hospital.The subjects were classified into 6 groups by age,and PSA levels were compared among groups.The correlations of FBG,TG,LDL-C,HDL-C with PSA were analyzed using multiple linear regression analysis.Results The level of PSA had the trend to increase with age.Positive association of TG,LDL with serum PSA level,but negative correlation between HDL and serum PSA level were noted in the group aged 60-64 years (r=0.10,0.15,0.12,P＜0.05).In the group aged 66-69 years,there was negative relationship between FBG and serum PSA(r= 0.10,P＜0.05).No relationship could be found in other groups (P＞0.05).ConclusionsPSA level may increase with age,but without relation with FBG,TG,LDL-C and HDL-C.
