Aims To study single dose toxicity of poly-phenols effective parts from Punica granatum,to eval-uate their safety,and thus to provide a theoretical basis for drug development and clinical use.To observe their protective effect on ethanol-induced gastric ulcer in rats.Methods 50 healthy Kunming mice were ran-domly divided into five groups and given different doses of polyphenols’effective parts from Punica granatum via intragastric administration.Toxicity and death in each group of mice were observed and recorded after administration for 14 d.The median lethal dose was calculated by Bliss method.70 rats were randomly di-vided into normal group,model group(constant volume of normal saline),sanjiuweitai particles(1 850 mg· kg-1 )group,colloidal bismuth subcitrate (33 mg · kg-1 )group and polyphenols effective parts from Puni-ca granatum low-dose,medium-dose,high-dose(430, 852,1 704 mg·kg-1 )groups.On the 9th day of 10 days’gavage,all except the normal group were fed ethanol (1.5 mL/only)to induce gastric mucosal inju-ry in rats with acute gastric ulcer.Gastric ulcer index, the rate of ulcer inhibition were calculated for each group.The morphological changes of gastric mucosa were observed.The gastric mucosa levels of PGE2 , NO,SOD and MDA were determined.Results The LD50 and 95%confidence limit of the polyphenols’ef-fective parts from Punica granatum were 8 520.9 mg· kg-1 and 7 291.2 ~9 914.4 mg·kg-1,respectively. Pathology showed that the organs receiving dose of 16 000 mg · kg-1 had different degrees of damage . Compared with the model group,the extract from Puni-ca granatum significantly repaired the gastric mucosa, and significantly increased the gastric mucosa levels of NO and reduced MDA content,and improved SOD content and the levels of PGE2 .Conclousion The dose of 5 063 mg · kg-1 of polyphenols effective part from Punica granatum showed no death.The dose of 16 000 mg · kg-1 of polyphenols effective parts from Punica granatum could cause varying degrees of dam-age in heart,liver,lung,kidney or the death of mice. The LD50 and 95% confidence limit of the polyphenols effective parts from Punica granatum were 8 520.9 mg ·kg-1 and 7 291.2 ~9 914.4 mg·kg-1,respective-ly.The extract from Punica granatum plays a protective role against gastric mucosa damage induced by absolute ethanol,and the mechanism may be related to promo-ting ulcer epithelial cells synthesis,enhancing mucosal regeneration function,regulating NO content and en-hancing antioxidant capacity.

Objective To discuss the prognosis of the metastatic prostatic carcinoma and analyze the relative factors. Methods From 2001 to 2002, 32 cases of matastatic prostatic carcinoma were admitted to our hospital, the ages ranging from 54 to 87, with the mean age of 71 years. All the diagnosis was proved by the six cores transrectal biopsy of the prostate. The serum PSA ranged from 63 to 2000 ng/ml. Two cases had the Gleason score of 2 - 6, 19 cases had the Gleason score of 7 and 11 cases had the Gleason score of 8 - 10. Preoperative routine examinations included serum testosterone, pelvic CT or MRI scan, CXR and bone scan. Twenty-seven cases were found to have osseous metastasis, among them 8 cases combined with lymph nodes metastasis, and 5 cases with lymph nodes metastasis only. All of them were treated with gonadectomy and the blockade of the androgen receptor (with Bicalutamide 50 mg/d or Flutamide 250 mg/d). It lasted 7 - 48 months with first endocrine therapy,and mid last time 23 months. After first line endocrine therapy failure, Diethylstilbestrol and Estramustine were used in the androgen-independent stage. Thirteen cases were not effective, and second therapy had effect to 19 cases and it lasted for 3 - 15 months. Results The follow-up periods ranged from 13 to 98 months, with the mean period of 33 months. Twenty-eight cases died, 4 cases survived. The median survial period was 37 months, 1-year survival rate was 100% (32/32), 3-year survival rate was 53%(17/32) , 5-year survival rate was 19%(6/23). As to the survival period, there were negative correlaions between survival and the level of PSA (r= -0. 262, P=0. 045) and the Gl-eason score (r=- 0. 624, P=0. 001). There were positive correlations between survival and the level of testosterone (r=0. 514, P=0. 008) and the age (r=0. 311, P = 0. 032). And there was no correlation between survival and the number of the positive cores of the biopsy (r=0. 211, F = 0. 158) and the clinical stage (r=0. 211, P = 0. 352). Conclusions As to the metastatic prostatic carcinoma, there are correlations between the survival and the levels of testosterone before treatment, age, the Gl-eason score and the level of PSA. There is no relationship between the survival period of the metastatic prostatic carcinoma and the number of the positive cores of the biopsy and the clinical stage.

B7-H3 is an immune checkpoint molecule overexpressed on the surface of a variety of tumors, and is is an ideal target for tumor immunotherapy. In this study, nitrolated T cell epitope designed in the early stage of the laboratory was used to construct an epitope vaccine that can target immune checkpoint B7-H3. The vaccine can significantly inhibit tumor growth in the CT26 colon cancer model, and has a significant synergistic effect with the PD-L1 protein vaccine. B7-H3 vaccine can increase the proportion of CD4+ T cells in splenic T lymphocytes and the proportion of CD8+ T cells in tumor-infiltrating T lymphocytes, while reducing the proportion of suppressor Treg cells in tumor-infiltrating CD4+ T lymphocytes, which effectively improves tumor immunosuppressive microenvironment. Research results suggest that the B7-H3 epitope vaccine can be used as an effective tumor vaccine candidate molecule.

BACKGROUND:Repairing tuberculosis bone defect has become a research focus with the development of anti-tuberculosis functional bone tissue engineering scaffold. OBJECTIVE:To evaluate the preparation, drug release performance and osteogenic properties of the anti-tuberculosis functional bone tissue engineering scaffold. METHODS:PubMed, Chinese Journal Ful-text Database, Wanfang databases were searched by computer for articles addressing functional bone tissue engineering scaffold for repair of tuberculosis bone defect. The keywords were“bone tissue engineering scaffold;tuberculosis;bone defect”in English and Chinese. RESULTS AND CONCLUSION:The anti-tuberculosis functional bone tissue engineering scaffold has good drug delivery, biocompatibility, osteogenic properties and anti-tuberculosis properties. As a good choice to avert bone defect relapse, the scaffold enables a long and stable drug release into bone defects to enhance the therapeutic efficacy of anti-tuberculosis drugs topical y. Given the technical deficiencies, we can only combine two drugs with the anti-tuberculosis bone tissue engineering scaffold, although the combined use of three or four anti-tuberculosis drugs is preferred. Additional y, a complete course of anti-tuberculosis treatment often lasts for 6-12 months, which cannot be achieved by the existing anti-tuberculosis bone tissue engineering scaffold. Up to now, the effect of this scaffold has not yet been confirmed in animal models, although how to prepare this scaffold has been reported.
