Objective To study the antitumor effects of photodynamic therapy (PDT)treated by ovarian cancer cell lysates in rat epithelial ovarian cancer in vivo. Methods Female Fischer344 rats of 6 -8 weeks were allocated to four groups ( n = 8 each) : PDT group ( inoculated intraperitoneal with PDT tumor cell lysates), freeze/thaw group ( inoculated intraperitonealy with freeze-thaw tumor cell lysates), normal saline group (inoculated intraperitoneal with normal saline) and control group. Rat epithelial ovarian cancer NuTu19 cells were injected into all rats by intraperitoneal at day 7,while injected with normal saline in control group. The number of tumor specific interferon-γ (IFN-γ) secreting splenocytes was quantified by enzyme linked immunospot(ELISPOT) assay, the cytotoxic T lymphocyte(CTL) activity of splenocytes was measured by lactate dehydrogenase(LDH) analysis and tumor growth and the survival time of rats were also observe& Results Stimulated by PDT tumor cell lysates, the number of tumor specific IFN-γ secreting splenocytes in PDT group, freeze/thaw group, normal saline group and control group were 448. 8±34. 2, 211.2±47.9,43.3 ± 11.1,16.1 ± 2.4 respectively, which were significant differences among of them ( P < 0.05). Stimulated by freeze/thaw tumor cell lysates, the number of tumor specific IFN-γ, secreting splenocytes in four groups were 151.7 ± 22.6,188.7 ± 53.0, 18.2 ± 12.2,8.8 ± 7.7 respectively, which were not significant differences among of them ( P>0.05 ). Cytotoxicity of splenocytes of PDT group increased significantly than that in other three groups(P <0.05). Except rats in control group were all alive until the experiment ended, the mean survival time of other rats were 234 d in PDT group, 171 d in freeze/ thaw group and 168 d in normal saline group, which in PDT group was significantly higher than those in freeze/thaw group and normal saline group ( P<0.05 ). Conclusions Rats treated by PDT tumor cell lysates could produce antitumor effects in vivo, which shown that induce tumor-specific immune response and prolong the life span.

As an important member of metabotropic glutamate receptors (mGluR), metabotropic glutamate receptor 1 (mGluR1) plays an important role in the signal transduction of central nervous system. Selective mGluR1 antagonists can block the signaling pathway activated by mGluR1 and exert a series of physiological actions including analgesia, antianxiety, antidepression, etc. Currently, the discovery and modification of selective mGluR1 antagonists have become a hot research focus. This paper reviews the structural catalogs of selective mGluR1 antagonists and their structure-activity relationships in the last decade.

Objective To investigate the protective role of Ulinastatin UTI on gut barrier of septic rats. Methods Twenty-two SD rats were divided into three groups: sham laparatomy(S), cecal ligation and punture(CLP), and CLP plus UTI. Septic rat model was estabilished through CLP method. Fluorescence spectrometry was used to measure FITC-dextran concentration from bowel lumen to portal vein. Ultrastructure of intestinal mucosa was observed under transmission eletron microscope (TEM). Results Twenty-one hrs after CLP septic symptoms in CLP plus UTI group were milder than those in CLP group. Portal concentration of FITC-dextran in CLP group was higher than that of S group[S (1.22?0.21) ?g/ml vs. CLP (2.51?0.56) ?g/ml, P

Objective To investigate effect of paclitaxel on expression of programmed death ligand-1 ( PD-L1 ) in the surface of cervical cancer TC-1 cells and its mechanism. Methods ①The cells were divided into two groups: paclitaxel group, paclitaxel combined with PKD blocker (G? 6976) group. There were 4 concentration gradient and 5 holes for each group, and each hole has its corresponding concentration of drugs. Influence of paclitaxel on TC-1 cell viability and effect of PKD blocker G? 6976 on IC50 value of paclitaxel were evaluated by MTT method.②The cells were divided into 0. 9% sodium chloride solution ( NS) group and paclitaxel group, There were 5 holes of each group. Effect of paclitaxel on PD-L1 expression on the surface of TC-1 cells were measured by immunohistochemistry.③The cells were divided into 4 groups:NS+DMSO group, G? 6976 group, paclitaxel group and paclitaxel+G? 6976 group. There were 5 holes for each group. Effect of paclitaxel and G? 6976 on PD-L1 expression on the surface of TC-1 cells were measured by immunohistochemistry. The expressions of PD-L1 on the surface of cells were measured by immunofluorescence treated with different drugs. Results The IC50 value of paclitaxel was 40 μg·mL-1 in paclitaxel group, and 38. 9 μg·mL-1 in paclitaxel combined with PKD blocker G? 6976 group, without significant difference between the two groups (P>0. 05). The expression of PD-L1 in the surface of TC-1 cells were significantly higher in paclitaxel group than in negative control group [(88. 48±13. 44)% vs. (39. 59±5. 99)%, P<0. 05]. The expression of PD-L1 in the surface of TC-1 cells was (79. 7%±4. 7)% after treatment with paclitaxel combined with PKD blocker G? 6976 for 24 h, and it was significantly lower than that in paclitaxel group [(96. 8±2. 5)%, P<0. 05]. Conclusion Paclitaxel promotes the expression of PD-L1 in the surface of TC-1 cells, which could be significantly inhibited by blocking PKD pathway. Paclitaxel may exert its effect through PKD pathway.

Objective To validate the therapeutic effect of acupuncture stage treatment on facial spasm and seek a better method for treating this disease. Method One hundred and forty patients were randomly allocated to stage treatment (50 cases), acupuncture (50 cases) and Western medicine (40 cases) groups. In the stage treatment group, treatment was divided into early, middle and late stages according to the patients’ duration of disease. Each stage provided acupuncture point injection of different medicine plus warm needling. The acupuncture group received conventional acupuncture with 1 hour retention of needles and the Western medicine group, oral administration of carbamazepine tablets, 0.2 g 3 times a day. After the completion of treatment course, a six-month follow-up was performed to determine no relapse or aggravation in the three groups and the therapeutic effects were evaluated using Cohen and Albert spasm grading criteria.Result The complete resolution rate was 56% (28/50) in the stage treatment group, 14.0% (7/50) in the acupuncture group and 20.0% (8/40) in Western medicine group. The complete resolution rate was significantly higher in the stage treatment group than in the acupuncture and Western medicine groups (P<0.05). The total efficacy rate was 100.0% (50/50) in the stage treatment group, 70.0% (35/50) in the acupuncture group and 60.0% (24/40) in the Western medicine group. The total efficacy rate was significantly higher in the stage treatment group than in the acupuncture and Western medicine groups (P<0.05).Conclusion Stage treatment has a marked effect on facial spasm.

Objective To investigate the diagnosis of a case with 7p15.3p22.1 microdeletion by applying array-based comparative genomic hybridization (array-CGH) and to analyze the relationship between the clinical manifestations and 7p15.3p22.1 microdeletion. Method Array-CGH technique was used to detect genomic copy number variations (CNVs) in an infant with normal karyotype after conventional chromosomal karyotyping. Results Array-CGH detected 7p15.3p22.1 deletion (chr7: 6777262-23981753), which was confirmed as pathogenic CNV after comparative analysis with database. Conclusion Array-CGH could serve as a useful complement for G-banding to be used in the clinical cytogenetic diagnosis.
