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.

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 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.

Objective To study the anti-neuroglioma effect of methyl-mercuric chloride(MMC) by observing the morphological changes of apoptotic neuroglioma cells induced with MMC in rats with brain neuroglioma.Methods The rat models of neuroglioma were established,and divided into two groups.The rats in experimental group were lavaged with MMC 1 week after injected with C6 glioma cells,10 mg?kg-1every day,the rats in control group were treated with sodium chloride at the same dose.24 d after inoculation all rats were sacrificed except natural death,the brain tissues were obtained,and the pathohistological changes were observed under light microscope and transmission electron microscope.Results The macropathological result showed that the tumor volume in experimental group was smaller than that in control group.Under light microscope,in experimental group the growth density of C6 ghioma cells was lower than that in control group,and the apoptotic cells with smaller volume and karyopyknosis were found.The result of transmission electron microscope showed that in experimental group,the glioma cells had some changes such as karyopyknosis,chromoplasm margination,nuclear fragmentation and vacuolar degeneration and so on.Conclusion MMC has inhibitory effect on the proliferation of C6 glioma in rats in vivo,its mechanism may be related to inducing the apoptosis of neuroglioma cells.

Objective To evaluate the relationship between carotid plaque instability and coronary heart disease by contrast-enhanced ultrasound. Methods Thirty-five patients with acute coronary syndrome (ACS) and 32 patients with stable coronary artery disease(sCAD) were included. Inclusion criteria were at least 1 carotid atherosclerotic plaque with thickness larger than 2.0 mm. Contrast-agent enhancement in the plaque was evaluated by visual interpretation and quantitative analysis. Results The percentage of soft plaque in ACS group was significantly higher than that in sCAD group ( P ＜0.001 ). The proportion of contrast-agent enhancement in patients with ACS was significantly than that in patients with sCAD( P =0. 037). The enhanced intensity in the plaque and the ratio of enhanced intensity in the plaque to that in the carotid artery lumen in patients with ACS were significantly larger than those in patients with sCAD ( P ＜0.001, P = 0.026, respectively). Sensitivity and specificity of prediction ACS were 74% and 60%,respectively,for enhanced intensity in the plaque and 86% and 67%, respectively, for ratio of enhanced intensity in the plaque to that in the lumen of the carotid artery. Conclusions The subjects with ACS had more intense contrast-agent enhancement than the subjects with sCAD. Contrast-enhanced ultrasound can be used to evaluate the relationship between carotid plaque instability and coronary heart disease.

OBJECTIVETo observe the short-term and long-term efficacies on primary dysmenorrhea treated with staging acupoint embedment therapy.

METHODSSeventy cases of primary dysmenorrhea were randomized into an embedment therapy group and a fenbid group, 35 cases in each one. In the embedment therapy group, the embedment therapy was applied twice during the menstrual cycle, one treatment 3 days before menstruation and one treatment during the 12th-14th days of menstruation, respectively. Guanyuan (CV 4), Zigong (EX-CA 1), Diji (SP 8) and Ciliao (BL 32) were the main acupoints in the treatment 3 days before menstruation. Shenshu (BL 23), Ganshu (BL 18) and Pishu (BL 20) were the main acupoints in the treatment during menstruation. In the fenbid group, fenbid was prescribed for oral administration, 0.3 g each time, twice a day, starting 3 days before menstruation till pain was relieved. The treatment of one menstrual cycle was one session. The continuous treatment of 3 menstrual cycles was required. The short-term and long-term efficacies were evaluated at the end of the 3rd cycle and in 3 months after the treatment terminal. The dysmenorrhea score was used to evaluate the efficacy. Visual analogue scale (VAS) and SF-36 were for the assessment of pain degree and life quality.

RESULTS(1) The total effective rate was 91.4% (32/35) in the embedment therapy group after the 3 menstrual cycles, which was better than 74.3% (26/35) in the fenbid group (P < 0.01). In the follow-up stage, the total effective rate was 91.4% (32/35) in the embedment therapy group, which was better than 40.0% (14/35) in the fenbid group (P < 0.01). (2) The differences were not significant in dysmenorrhea score and VAS score after the 1st and 2nd menstrual cycle treatments between the two groups (all P > 0.05). In the 3rd menstrual cycle and the follow-up stage, the dysmenorrhea score and VAS score were reduced obviously in the embedment therapy group as compared with those in the fenbid group (P < 0.05, P < 0.01). The rebound effect occurred in the follow-up stage in the fenbid group. (3) In the 3rd menstrual cycle and the follow-up stage, the improvement in the total score of life quality of the embedment therapy group was superior apparently to the fenbid group (P < 0.05, P < 0. 01).

CONCLUSIONThe staging acupoint embedment therapy achieves the superior short-term and long-term efficacies as compared with the oral administration of fenbid in the treatment of primary dysmenorrhea. As the symptoms of dysmenorrhea and pain are relieved, the life quality is improved.
