Objective To investigate the prevalence of Toxoplasma gondii infection and awareness of toxoplasmosis?related knowledge among women with poor pregnant outcomes in Wuxi City. Methods A total of 217 women with poor pregnant out?comes from Wuxi City during the period of January 2011 to December 2015 were randomly selected as the study subjects( a study group),while 250 women with normal pregnancy were served as controls(a control group). The sero?prevalence of T. gon?dii infection was detected by using ELISA and compared between the study and control groups. The awareness of toxoplasmosis?related knowledge was investigated by using a self?designed questionnaire and compared between the study and control groups. Results The positive rate of anti?Toxoplasma antibody was 30.88%in the study group,which was significantly higher than that (8.8%)in the control group(χ2 =36.7,P<0.01). The positive rates of anti?Toxoplasma IgG and IgM antibodies were 20.74%and 10.14% in the study group respectively,which were significantly higher than those(6% and 2.8%)in the control group (χ2=22.53 and 10.74,both P values<0.01). In addition,the positive rates of anti?Toxoplasma,anti?Toxoplasma IgG and IgM antibodies were significantly higher in the women with missed miscarriage,natural abortion,stillbirth and birth defect than those in the women with normal pregnancy(all P values<0.05). The awareness rates of“Do you hear about Toxoplasma or toxo?plasmosis?”(P<0.01),“Do you know that breeding pet cats or dogs may cause Toxoplasma infection?”(P<0.05)and“Do you know that pregnancy women require the detection of Toxoplasma infection?”(P<0.01)were significantly lower in the study group than those in the control group,while no significant differences were seen in the awareness rates of“Do you know that eat?ing hot pot may cause Toxoplasma infection?”,“Do you know that the use of chopping block in regardless of cooked and un?cooked food may cause Toxoplasma infection?”,“Do you know that Toxoplasma infection may transfer from mother to fetus?”,“Do you know that Toxoplasma infection may cause adverse pregnant outcomes like abortion,stillbirth or fetal abnormalities ?”, and“Do you know that the women infected with T. gondii during pregnancy require treatment?”between the two groups(all P values>0.05). Conclusions This study demonstrates higher prevalence of T. gondii infection in women with poor pregnant out?comes than in those with normal pregnancy in Wuxi City. Considering the harm of T. gondii infection during pregnancy and the low awareness of toxoplasmosis?related knowledge in pregnant women,the health education of toxoplasmosis?related knowledge should be strengthened,especially for pregnant women,so as to reduce the prevalence of T. gondii infection among pregnant women to improve the better child?bearing and rearing level.

Aim To explore the apoptotic effect of mimics of manganese superoxide dismutase(MnSODm)on human leukemia cell line K562 in vitro and the possible molecular mechanisms.Methods Human leukemia K562 cells were used as the target cells.The cell proliferating activity was examined by a MTT colorimetric assay,and the apoptosis of K562 cells was assessed with FITC-Annexin V and propidium iodide(PI)double staining and morphological changes.The expressions of bcl-2 and bax mRNA were detected by reverse transcription polymerase chain reaction(RT-PCR),and flow cytometry(FCM)was employed to measure the expressions of Bcl-2 and Bax protein,mitochondrial inner membrane potential(??m),Cytochrome C(Cyt C)release and Caspase-3 activity.Results The proliferation of K562 cells was obviously inhibited by 0.5~10 mg?L-1 MnSODm(P

Objective To investigate the effects of therapeutic exercise(cage running)on the expression of Bel-2 and Bax in neuronal cells after cerebral hemorrhage(ICH)in rats. Methods A total of 120 male Sprague-Dawley rats weighing 270 to 300 g were divided into a trial group(ICH and exercise group,n=40),a control group (ICH only,n=40)and a sham-operated group(sham ICH operation and no exercise,n=40).The brains were removed at 7,14,21 and 28 days after ICH.The activation of Bcl-2 and Bax WaS measured by immunohistochemical techniques,Western blotting and reverse transcriptase polymerase chain reaction(RT-PCR).Results (1)Bel-2-positive and Bax-positive cells appeared in tissues surrounding the hematoma in the cortex.The number of Bcl-2-posotive and Bax-positive cells was nearly zero in the sham-operated group.In the trim group.the number of Bcl-2-positive cells increased significantly from the 21 st to the 28th day.Bax.positive cells decreased from the 7th to the 28th day after ICH when compared with the control group and the sham-operated group.(2)The expression of Bcl-2mRNA and Bax-mRNA as shown by Western blotting and RT-PCR methods was synchronous with the immunohistochemistry results.The peaks of Bcl-2mRNA and BaxmRNA expression were a little earlier than those of Bcl-2 and Bax proteins. Conclusion Exercise can mitigate neuronal cell apoptosis by upregulating the expression of Bcl-2 and Bcl-2 mRNA,and downregulating the expression of Bax and Bax mRNA.

Objective To explore the infections of human cytomegalovirus (HCMV) in chronic hepatitis C patients and the hepatic impairment in chronic hepatitis C patients co-infected with HCMV.Methods HCMV-DNA was determined by fluorescence quantitative-PCR (FQ-PCR) in 95 patients with chronic hepatitis C (observation group) and 95 healthy controls(control group) and HCMV active infections were analyzed.HCV-RNA was determined by FQ-PCR in observation group,and the difference of HCMV-DNA positive rate between high HCV-RNA(> 104 copies/ml) and low HCV-RNA(≤ 104 copies/ml) was analyzed.Alanine aminotransferase (ALT),aspartate aminotransferase (AST) were determined by rate method in two groups and the hepatic impairment was analyzed.Results Twenty-five cases with positive HCMV-DNA in observation group,the positive rate was 26.3%(25/95).Five cases with positive HCMV-DNA in control group,the positive rate was 5.3%(5/95).There was significant difference between two groups for HCMV-DNA (x2 =14.29,P <0.01).Twenty-one cases with positive HCMV-DNA in 43 cases of high HCV-RNA patients,the positive rate was 48.8%(21/43).Four cases with positive HCMV-DNA in 52 cases of low HCV-RNA patients,the positive rate was 7.7%(4/52).There was significant difference between the two (x2 =19.90,P < 0.01).ALT,AST in observation group was higher than that in control group (P < 0.01).ALT,AST in chronic hepatitis C patients positive for HCMV-DNA was higher than that in chronic hepatitis C patients negative for HCMV-DNA significantly (P < 0.01).Conclusions HCMV in chronic hepatitis C patients becomes active again and co-infects easily.When chronic hepatitis C patients co-infect HCMV actively,hepatic is further injured.

Thyroid-associated orbitopathy (TAO) is an inflammatory autoimmune disorder.The mast serious complication of TAO is dysthyroid optic neuropathy (DON),which can lead to permanent vision loss because of volume expansion in the orbital apex.Orbital radiation therapy (ORT) is an anti-inflammatory treatment used in the treatment of active TAO.Clinical studies support radiotherapy as having a modest effect on DON,and early radiotherapy may protect against disease progression to DON.Current studies suggest that radiotherapy is generally safe.However,risks still exist in some cases.The possible effects of radiotherapy on TAO,especially complicated with DON,are reviewed.The effects of radiotherapy on DON are not completely known,and evidence from standardized,prospective,and multicenter clinical trials is still lacking.

Objective To identify the gene mutations of an inherited coagulation factor Ⅶ deficiency pedigree.Methods PCR and DNA sequencing were used to identify the FⅦ gene mutations in the proband.The identified mutations were validated by PCR followed by restriction fragment length polymorphism technique or DNA sequencing.100 healthy volunteers were chosen randomly as controls. Results R1S2Q and IVS6+1G→T double heterozygous mutations were discovered in the Droband.The pedigree analysis showed that R152Q missense mutation inherited from his father,and IVS6+1G→Twas from his mother. The R1S2Q missense mutation in exon 6 was not found in 100 healthy volunteers. Conclusion The congenital deficiency of F Ⅶ in the proband might be caused by the coinheritance of the R152Q missense mutation in exon 6 and the splicing donor site mutation ( ⅣS6+1G→T)in intron 6.
