To investigate the prevalence of Enterococcus faecalis in saliva and filled root canals of patients requiring endodontic retreatment for apical periodontitis. Patients with apical periodontitis who were referred for endodontic retreatment were examined. The type and quality of the restoration, symptoms, quality of obturation were recorded. During retreatment, an oral rinse sample and root canal sample were cultured using brain-heart infusion agar and bile esculinazide agar to select for E. faecalis. The 16S rRNA technique was used to identify E. faecalis. A total of 32 women and 22 men (mean age: 38 years; s.d.: 11 years) and 58 teeth were studied. The prevalence of E. faecalis was 19% in the saliva and 38% in the root canals. The odds that root canals harbored E. faecalis were increased if the saliva habored this bacterium (odds ratio=9.7; 95% confidence interval=1.8-51.6; P<0.05). Teeth with unsatisfactory root obturation had more cultivable bacterial species in root canals than teeth with satisfactory root obturation (P<0.05). E. faecalis is more common in root canals of teeth with apical periodontitis than in saliva. The prevalence of E. faecalis in root canals is associated with the presence of E. faecalis in saliva.

Objective To investigate the effect of movie enjoyment on emotion of male patients with chronic schizophrenia.Methods A total of 62 standard patients with chronic schizophrenia from September to November 2011were selected and randomly divided into the experimental group(30) and the control group(32) by using a random number table.Patients in experimental group received movie enjoyment and routine rehabilitation project,while those in the control group received only routine rehabilitation project.Before the intervention and 12 weeks after the intervention,the patients were investigated with the Positive and Negative Affect Scale for efficacy assessments.Results After the nursing intervention,the scores of positive and negative affect were (30.79 ± 7.54) and (18.07 ± 5.97) respectively in the experimental group in contrast to (22.29 ± 8.14) and (18.00 ± 7.79) before the intervention,the difference was statistically significant (t =3.97,4.85,respectively;P ＜0.01).After the nursing intervention,the scores of positive and negative affect were(21.41 ±7.40) and (17.72 ± 7.03)respectively in the control group while were (23.25 ± 6.37)and (16.50 ± 6.08) before the intervention,the difference was statistically significant (t =2.67,1.98,respectively; P ＜ 0.05).There was statistically significant between the two groups in the scores of positive and negative affect after intervention(t =5.69,6.78 ;P ＜ 0.01).Conclusions The movie enjoyment can help improve positive emotions affect of patients with chronic schizophrenia.

OBJECTIVETo search for an optimum method for testicular prothesis implantation in the treatment of testis loss.

METHODSWe retrospectively analyzed the surgical methods and outcomes of 53 cases of terminal prostate cancer and 4 cases of unilateral testicular torsion treated by implantation of testicular prothesis with the polypropylene mesh.

RESULTSThe 57 male patients all received testicular prothesis with the polypropylene mesh. All the patients were satisfied with the appearance and size of the scrotum after surgery. No scrotal hematoma, prosthesis infection, or autoimmune disease occurred postoperatively.

CONCLUSIONTestis loss is not a rare condition clinically, for the treatment of which surgical implantation of testicular prothesis with the polypropylene mesh can achieve both a fine tissue compatibility and a desirable scrotal appearance.

In the fast pace of modern life and under the heavy work pressure, the prevalence of depression has increased year by year. Meanwhile, the demands for antidepressant drugs have also grown, especially the high-efficiency and low-toxicity natural antidepressant drugs, mainly including polyphenols, flavonoids, organic acids, alkaloids and terpenoids. Cytochrome P450 (CYP450) is a type of enzymes involving oxidative metabolism of drugs in vivo, and can change the pharmacokinetics and efficacy of drugs. Therefore, it is of important significant to define the effect of natural antidepressant drugs on CYP450 in human bodies, in order to improve the rational clinical medication, avoid drug interactions and reduce adverse reactions.

ObjectiveTo observe the clinical effect of acupoint application on lipid metabolism in elderly diabetics with hyperlipidemia.Methods60 elder diabetics were divided into two groups.In the drugs group,patients were purely treated with simvastatin or lipanthyl.In the acupoint group, patients received acupoint application.The serum total cholesterol(TC), triglyceride (TG), low-density lipoprotein (LDL-C), high-density lipeprotein (HDL-C), aPoprotein A(ApoA) and apoprotein B(ApoB) ere measured respectively.Adverse events were observed.ResultsThe levels of TC、TG、LDL-C、ApoB were significantly dechned(all P ＜0.01 ～0.05).However,the rates of reduce lipid had no significant difference in two groups(P ＞0.05).The levels of HDL-C and ApoA were increased in the drugs group,but the homologous levels in the acupoint group showed no significantly change(all p ＞ 0.05).The adverse reaction in the acupoint group was significantly lower than that in the drugs group(P ＜0.05).ConclusionAcupoint application could decrease the blood lipid spectrum in the senile diabetics with hyperlipidemia.This therapeutics could reduce adverse drug reactions.

Objective To investigate the potential application of human transforming growth factor-beta-1 (hTGF-β1) gene mediated by type 2 recombinant adeno-associated virus (rAAV2) vector inducing chondrogenic differentiation of canine mesenchymal stem cells (MSCs) in vitro. Methods Canine MSCs from bone marrow were isolated and cultured in vitro by density gradient centrifngation and adherence screening methods. The morphology of MSCs was observed by inverted phase contrast microscope and Giemsa stain. Flow eytometry was used to detect surface antigens of MSCs, The third generation of MSCs were transfected by rAAV2-hTGF-β1 with or without MOI of 1 ×105 v.g./cell or 5×105 v.g./cell. The expression of hTGF-β1 was detected by Western blot after 10 days, and TGF-β1 synthesis was determined by ELISA at 3, 6 and 9 day, respectively. After 2 weeks of culturing, mRNA expressions of type Ⅱ collagen and aggrecan were determined by RT-PCR and the collagen Ⅱ protein was detected by immunocytochemistry. Results The MSCs appeared to be morphologically spindle-shaped and showed active capability of proliferation both in primary and passage generations. Flow cytometry analysis indicated that MSCs were universally positive for CD29, CD44 and CD105, but negative for CD34 and CD45. TGF-β1 expression can be observed by Western blot after 10 days in two transfection groups, MOI of 5 × 105 group and MOI of 1× 105 group. With the extension of time, the contents of hTGF-β1 increased in the two groups detected by ELISA, while there was a significant difference between them two (P < 0.01). After 2 weeks of transfection of MSCs by rAAV2-hTGF-β1, the expression of collagen Ⅱ and Aggreacan mRNAs were positive. It also showed positive of collagen Ⅱ detected by immunocytochemistry. Conclusion Canine MSCs show chondrogenesis differentiation after induction by Type 2 rAAV mediated transfer of TGF-β1 gene. The process is a potential application for cartilage tissue engineering.

Objective To study the protective effect of codon optimized TPI DNA vaccine against Schistosoma japonicum infection.Methods Sixty female BALB/c mice were randomly divided into 5 groups.The mice were injected through musculus quadriceps fexoris with 100 ?g pcDNA 3.1 control(Group A), pcDNA3.1-TPI(Group B), pcDNA 3.1-TPI-mHSP70(Group C), pcDNA3.1-TPI.opt(Group D), and pcDNA3.1-TPI.opt-mHSP70(Group E) respectively.All mice were immunized for three times with an interval of two weeks.The mice were challenged with(40?1) cercariae of S.japonicum per mouse by abdominal skin penetration 4 weeks after the last immunization, and sacrificed at 42 days post-challenge, the number of worms or hepatic eggs was counted.Blood was taken for the detection of IgG, IgG1, and IgG2a 2 days before immunization and before challenge, respectively.Spleen cells of 2 mice from each group were cultured and stimulated with ConA and rSjCTPI peptide, and the supernatant was collected for detection of IL-2, IL-4, IL-5, IFN-?, and TNF by flow cytometry.Results ELISA showed that the mice in groups B, C, D, and E produced specific IgG and IgG1, IgG2a antibody isotypes, and the ratio of IgG2a/IgG1 was 1.73, 2.06, 2.44, and 3.09, respectively.The levels of IL-2, IFN-? and TNF in groups D and E were higher than that of groups B and C.The worm reduction rate and hepatic egg reduction rate in groups D(36.03%, 41.7%) and E(39.03%, 46.85%) were higher than those of groups B(26.28%, 28.35%) and C(28.38%, 31.39%)(P
