Objective To investigate the protective immunity in mice immunized with recombinantBifidobacteria bifidum(Bb)-Eg95 vaccine of Echinococcus granulosus (Eg) and challenged with Eg protoscoleces.Methods Fifty-six female BALB/c mice 12-14 weeks old and weighed 20-25 g were vaccinated with the recombinant Bb-Eg95 vaccine subcutaneously,intramuscularly,intranasally and orally,respectively,with blank vector,Bb and medium of solution(MRS) as control,8 mice in each group.Mice were challenged with Eg protoscoleces on week 8 after immunization and killed on week 25 after infection.The weight of hydatid cyst was measured and the decreased larva rate was calculated.Sera were collected to determine the levels of IgE,IgG and its subclasses by enzyme linked immunosorbent assay(ELISA).Splenocytes were collected and cultivated to test the proliferation of splenocytes using methyltetrazolium (MTT) assay under EgAg and concanavalin A (ConA) stimulation.The results were compared with analysis of variance and the comparison between two groups was performed with LSD-t test.Results There was significant difference in the weight of hydatid cyst between groups (F =11.062,P ＜ 0.05).Compared with MRS control group[(0.075 ± 0.019)g],the hydatid cyst weight decreased in subcutaneous group [(0.050 ± 0.013)g],intramuscular group[(0.050 ± 0.019)g],intranasal group[(0.028 ± 0.016)g] and oral group [(0.031 ± 0.018)g,all P ＜ 0.01).Compared with subcutaneous and intramuscular groups,the hydatid cyst weight decreased in intranasal and oral groups(all P ＜ 0.05).The decreased larva rate was inversely proportional to the weight of hydatid cyst.There was significant difference in the levels(obsorbancy,A) of IgG,IgG2a,IgG2b,IgG1,IgG3 and IgE between these groups(F =21.774,36.977,27.071,14.746,10.131,9.444,P ＜ 0.05 or P ＜ 0.01).Compared with MRS control group (0.015 ± 0.002,0.002 ± 0.001,0.003 ± 0.001),the levels of IgG,IgG2a and IgG2b increased in subcutaneous group(0.022 ± 0.004,0.007 ± 0.002,0.008 ± 0.002),intramuscular group (0.023 ± 0.003,0.008 ± 0.002,0.007 ± 0.002),intranasal group(0.032 ± 0.007,0.012 ± 0.002,0.013 ± 0.004)and oral group(0.028 ± 0.006,0.010 ± 0.003,0.010 ± 0.002,P ＜ 0.05 or P ＜ 0.01).Compared with subcutaneous and intramuscular groups,the levels of IgG,IgG2a and IgG2b increased in intranasal and oral groups(P ＜ 0.05 or P ＜ 0.01).Compared with MRS control group(0.009 ± 0.001,0.009 ± 0.002,0.009 ± 0.001),the levels of IgG1,IgG3 and IgE decreased in subcutaneous group(0.022 ± 0.004,0.007 ± 0.002,0.008 0.002),intramuscular group(0.004 ± 0.001,0.004 ± 0.001,0.004 ± 0.002),intranasal group(0.005 ± 0.002,0.005 ± 0.003,0.005 ± 0.002)and oral group(0.005 ± 0.001,0.004 ± 0.002,0.004 ± 0.003,all P ＜ 0.01).There was significant difference in the proliferation of splenocytes in the supernatant of cultured splenocyte,of cultured splenocyte + EgAg and of cultured splenocyte + ConA(F =63.975,359.833,167.399,P ＜ 0.01).There was significant difference in the proliferation of splenocytes inside groups(F =6741.955,4953.667,869.320,201.235,175.413,139.653,169.994,all P ＜0.01).Compared with the cultured splenocyte the proliferation of splenocytes increased in the cultured splenocyte +EgAg and splenocyte + ConA (all P ＜ 0.01).Compared with the cultured splenocyte + EgAg,the proliferation of splenocytes increased in the cultured splenocyte + ConA(P ＜ 0.01).Conclusion An effective and protective immunity is induced by the recombinant Bb-Eg95 vaccine of Eg in mice.

Objective To summarize the complications of the single-port transumbilical laparoscopic pyeloureteroplasty.Methods From August 2009 to December 2014, 162 surgical procedures were performed in our institute with the single-port transumbilical laparoscopic pyeloureteroplasty.Medical records of each procedure were retrospectively evaluated.139 patients were male and 23 female, aged from 1 month to 14 years and the median age of 2 years.127 patients were operated on the left side and 32 on the right side.3 patients were operated on the bilateral side.All children were supplemented with preoperative ultrasound, renal dynamic imaging and MRU to identify the ureteropelvic junction obstruction.Intraoperative and postoperative complications were graded according to the Satava and Clavien classifications respectively.Major complications were defined as Satava grade Ⅱ or higher, and Clavien grade Ⅲ or higher.Results There was no injury of vascular or visceral organs and no blood transfusion, and there was no serious intraoperative complications.One hundred and forty-three cases were followed up, and 23 cases (16.1％)presented with postoperative fever (＞ 38 ℃C) (Clavien Ⅰ), 2 cases (1.4％) with urinary extravasation diagnosed by perirenal fluid collection(Clavien Ⅰ).All these cases recovered after being given symptomatic treatment.7 cases (4.9％) presented with postoperative repeated urinary infection (Clavien Ⅱ).5 cases received postoperative reoperation due to the obstruction of the anastomic site (Clavien Ⅲ b), and 2 cases were under debridement as the greater omentum was drawn out along with the negative pressure drainage tube(Clavien Ⅲ a).In summary, the incidence of severe postoperative complications was 4.9％.Conclusions Though there existed some postoperative complications of the single-port transumbilical laparoscopic pyeloureteroplasty, the incidence of serious complications was low and the overall prognosis could be good.

Objective To compare the outcomes of Yang-Monti channels and appendix in the practice of catheterizable continent urinary conduits.Methods Retrospective analyses were conducted in 27 cases with neurogenic bladder from July 2009 to December 2015,including 8 male and 19 female patients whose average age at surgery was 7.6 years old (range:1.5-16 years).The average bladder volume is (203.8 ± 126.0) ml.The bladder compliance values of 24 cases are lower than 20 ml/cm H2O.Seventeen cases had urinary infection combined with fever before surgery,while 6 cases had stress urinary incontinence and 17 cases had dysuria.Seven cases including 2 male patients underwent urinary diversion with YangMonti channels (YM group) and the average age at surgery for patients was 6.7 years old (range:4-16years).Twenty cases including 6 male patients underwent urinary diversion with appendix (AP group) and the average age at surgery for patients was 8.0 years old(range:1.5-14 years).The 3-day urinary diaries were collected in all cases including their records of average catheterization interval,average catheterization volume,stoma stenosis and stoma leakage.The data between the two groups was compared and the statistical analysis was performed.Results Of the 7 patients undergoing Yang-Monti channels,2 cases underwent open surgery and 5 cases underwent laparoscopic surgery in which 2 cases transferred to open surgery.The stoma stenosis occurred in 1 case and the stoma leakage occurred in 1 case.The average catheterization volumc is (239.3 ± 76.2) ml and the average catheterization interval is (2.8 ± 0.9) h.Six patients in the group were followed up less than 3 years,of which the average catheterization interval is (2.6 ± 0.8) h.Of the 20 patients undergoing appendix channels,3 cases underwent open surgery and 17 cases underwent laparoscopic surgery in which 1 case transferred to open surgery.The stoma stenosis occurred in 1 case and the stoma leakage occurred in 2 cases.The average catheterization Volumee is (257.0 ± 67.4) ml and the average catheterization interval is (3.9 ± 0.9)h.Six patients in the group were followed up less than 3 years,of which the average catheterization interval is(3.5 ± 1.0) h.There was no difference in stoma stenosis and stoma leakage and average catheterization volume between the two groups (P ＞ 0.05).There was no difference in average catheterization interval between the patients of two groups who were followed up less than 3 years (P ＞ 0.05).Conclusions Yang-Monti conduits are durable and reliable,which was similar with appendix conduits.

This article reports a preliminary observation oh the growth of cercarial embryo of S.japonicum in defined medium cultivated one week in vitro. When extract of head-foot tissue of Oncomelania hupensis was added to the medium contained 1/2 RPMI 1640, the length of cercarial embryo increased. While liver extract of the snail was added to the same medium, the growth was inhibited.It seemed that the extract of snail liver tissue might be poisonous to the cercarial embryo.

To assess early treatment for fracture of the maxillofacial bone complicated by cerebral injury, 120 patients were retrospectively reviewed. The change in GCS, the incidence of stress ulceration, nosocomial pneumonia and the injury of liver or kidney were determined 1 week after fixation of the fracture of the maxillofacial bone at different stages. There was no significant influence of the time of the operation on the severity of brain injury and the incidence of the complications. It is our assertion that the bone fracture could be fixed at an earlier stage, and RIMF is a kind of satisfactory fixation method.

Objective: To observe the effects of He-Ne laser therapy instrument on bone marrow mesenchymal stem cell (BMSC) growth and neural differentiation potential. Methods: The primary BMSCs from Sprague-Dawley rats were taken using whole bone marrow culture. The passage 3 cells were randomly divided into an experimental group (He-Ne laser therapy instrument treated for 10 min) and a control group (exposing in the air for the same time) according to whether they were treated with the He-Ne laser therapy instrument or not. The cell proliferation activity was measured with cell counting kit-8 (CCK-8) assay. Apoptosis detection was performed using flow cytometry. The cell vitality was detected by Trypan blue staining. Human neural stem cell differentiation potential was identified by immunofluorescence technique. Results: Circled digit oneCells showed a fibroblast-like adherent growth. The phenotypic identification results revealed that the expressions of CD29 and CD90 were positive, but the expression of CD45 was negative, and it is consistent with the characteristics of the BMSC phenotype. Circled digit twoThere was no significant difference in the proliferative activity between the experiment group and the control group, P > 0.05. Circled digit threeThere were no significant differences between the early apoptosis rate (1.10 ± 0.26%) in the experiment group and that (1.43 ± 0.06%) in the control group, as well as the cell viability (96.2 ± 0.6%) in experiment group and that (96.2 ± 0.7%) in the control group. Circled digit fourSimilar to the control group, BMSCs in the experiment group showed the suspended neurospheres after being cultured in neural stem cell culture medium. Immunofluorescence staining showed that the nestin staining of neurosphere cells was positive. Conclusion: He-Ne laser therapy instrument has no significant effects on the proliferation and viability of BMSCs. It does not cause apoptosis and change the potential of BMSCs to neural stem cell differentiation.
