AIM: To investigate the clinical effect of compound anisodine on patients with paralytic strabismus and the influence on malondialdehyde ( MDA ) and superoxide dismutase ( SOD) .
●METHODS: Seventy cases diagnosed with paralytic strabismus from Jun. 2008 to Dec. 2014 were selected as treatment group; another 70 cases with paralytic strabismus from Oct. 2000 to Jan. 2008 were chosen as control group. The control group was given with conventional therapy, and treatment group was additionally injected with compound anisodine subcutaneously on the basis of the control group. Treatment lasted for two courses about 28days. The effect of compound anisodine on patients with paralytic strabismus was evaluated and the serum level of MDA and SOD was also measured before and after treatment.
●RESULTS: ln treatment group, 54 cases were cured (77%), 14 cases improved (20%) and 2 cases had no response ( 3%) and total efficiency reached to 97%. ln control group, 32 cases were cured ( 46%) , 21 cases improved ( 30%) and 17 cases had no response ( 24%) and total efficiency was 76%. The cure rate and total efficiency of treatment group were significantly higher than that of control group (P<0. 05). Before treatment, the level of SOD and MDA was equal in two groups. After treatment, increased SOD level and decreased MDA level was observed in both groups. However, compound anisodine were significantly increased SOD level and reduced MDA level when compared with conventional therapy (P<0. 05).
●CONCLUSION: The compound anisodine shows the beneficial effect on patients with paralytic strabismus. Compound anisodine may exert the effect via increasing SOD and reducing MDA.

Objective:To explore the feasibilitv of stereotactic minimally invasive aspiration of small thalamic bemorrhage.Methods:Twenty-two patients with small thalamic hemowhage(5 to 10 mL)were divided into two groups:a stereotactic group(n=10)and a control group(n= 12).The patients in the stereotactic group received stereomctic minimally invasive puncture and drainage of hematomas.According to the condition,repeated infusion of urokinase(10-20 kU) into the hematoma cavities were administered 12 hours after the procedure,and the hematomas were irrigated and drained so as to removal of them completely after retaining for 2-4 hours, The appropriate symptomatic treatment was administered in the patients in both groups.National Institutes of Health Stroke Scale(NIHSS)scores were determined 14 and 30 days before and after the treatment in all the patients.The reductiom of the NIJSS scores (as compared with those before treatment)were calculated at day 14 and 30 respectively after the treatment. Results:The reductiom of the NIHSS scores in the stereotactic group at day 14 and 30 were significantly higher than those in the control group.It was suggested that the neurological functional recovery of the patients was faster after stereotmtic minimally invasive puncture and drainage of intracranial hematorna in the stereotactic group.Concision:The stereotactic minimally invasive puncture and drainage of intracranial hematoma may significantly improve the outcome in patients with small thalamic hemorrhage.

Objective To investigate the role and mechanism of B7-H4, a negative costimulatory molecule, in mediating the immunomodulatory effects of mesenchymal stem cells C3H10T1/2 (C3H10) on T cell polarization. Methods The lentiviral vectors that carried the shRNA targeting mouse B7-H4 were transfected into mouse mesenchymal stem cells (C3H10-B7-H4). The cells were co-cultured with PHA-acti-vated mice spleen lymphocytes before and after the transfection. ELISA was performed to detect the concen-trations of cytokines in supernatants of cell culture in order to elucidate the effects of B7-H4 expressed by C3H10 on T cell polarization. A mouse model of experimental allergic encephalitis (EAE) was established. Fifty C57BL/6 mice were divided into five groups including control group, EAE group, C3H10 group (injec-ting EAE mice with C3H10 cells), C3H10-NC group ( injecting EAE mice with C3H10-NC cells) and C3H10-B7-H4 group (injecting EAE mice with C3H10-B7-H4 cells). ELISA was performed to detect the soluble form of IL-2, IL-17, IFN-γ and IL-4 in plasma samples. Results Knocking down the B7-H4 gene with shRNA significantly decreased the expression of B7-H4 on C3H10 cells, which weakened the inhibitory effects of C3H10 cells on the secretion of IL-2, IL-17 and IFN-γ by spleen lymphocytes. The therapeutic effects of C3H10-B7-H4 cells on mice with EAE were weakened after silencing the B7-H4 gene expression, which was manifested as higher nerve function score and earlier onset and bring forwarded peak time of EAE than those of the C3H10 group. Treating EAE mice with C3H10-B7-H4 cells was less efficient in inhibiting the expression of IL-2, IL-17 and IFN-γin plasma. However, knocking down the B7-H4 gene had no signif-icant effect on the expression of IL-4 in terms of treating EAE with C3H10 cells. Conclusion The co-inhib-itor molecule B7-H4 expressed on C3H10 cells mediated the treatment of EAE with C3H10 cells by regula-ting Th1 and Th17 effector T cells.

OBJECTIVETo observe the therapeutic effect and safety of perineal, crissal and progenital pruritus treated with acupuncture according to differentiation.

METHODSSelf-control method was applied in these 32 cases. Changqiang (GV 1), Huiyin (CV 1), Qugu (CV 2), Sanyinjiao (SP 6) and Ashi points etc. were punctured as main points, and adjunct points were added according to differentiation: Taichong (LR 3) and Ququan (LR 8) etc. were added for wind and heat excess of liver meridian, Xuehai (SP 10) and Quchi (LI 11) etc. were added for blood deficiency and wind dryness. Itchiness, skin lesions sign scores and therapeutic effects were observed before and after treatment.

RESULTSThe total scores of itchiness before and after treatment were 6.06 +/- 1.46 and 2.19 +/- 1.71 respectively, and the total scores of skin lesions sign were 4.38 +/- 2.21 and 1.50 +/- 1.44, indicating that the scores and the total scores of itchiness and skin lesions sign reduced obviously after treatment (P < 0.05, P < 0.01); the cured and markedly effective rate was 73.4% (11/15) for wind and heat excess of liver meridian, and 70.6% (12/17) for blood deficiency and wind dryness, presenting similar therapeutic effect (P > 0.05). Hematoma or ecchymosis appeared in 2 cases, and disappeared spontaneously after 2-3 days, without obvious adverse reaction.

CONCLUSIONSimple perineal, crissal and progenital pruritus treated with acupuncture according to differentiation is effective, safe and applicable.

OBJECTIVETo explore the therapeutic value of BCSC-1 in tumor gene therapy.

METHODSRecombinant adenovirus Ad5-BCSC-1 was prepared. Cell proliferation was assayed using CellTiter 96 Aqueous one solution cell proliferation assay kit. Ad5-BCSC-1 was injected into tumor with Ad5-egfp or with PBS injection as controls. The injections were repeated one weak later. After another 2 weeks, the mice were sacrificed and the tumors were excised and weighed.

RESULTSThe growth of the CNE-2L2 cell infected with Ad5-BCSC-1 in vitro was remarkably slower than that of the controls, the wild type cell and the cell infected with Ad5-egfp. In contrast to the controls, the cells infected with Ad5-BCSC-1 aggregated and formed huge messes in the culture. The average weight of the CNE-2L2 tumors in mice was (2.28 +/- 0.73), (2.07 +/- 0.40), and (0.58 +/- 0.32) g for the tumors injected with PBS, Ad5-egfp, and Ad5-BCSC-1, respectively (Ad5-BCSC-1 vs. PBS or Ad5-egfp, P<0.05).

CONCLUSIONIntra-tumor injection of Ad5-BCSC-1 can suppress the growth of CNE-2L2 tumor in nude mice, suggesting that BCSC-1 gene therapy may be effective for tumors with low or no expression of BCSC-1 gene.

OBJECTIVETo explore the possibility of treating solid tumor with siCD44.

METHODSHuman nasopharyngeal carcinoma cell CNE-2L2 with high expression of CD44 was used in this study. The malignant activities of cells were examined by colony formation test, tumorigenesis, and lung metastasis of the tumor in nude mice. Ad5-siCD44 was constructed and adenoviruses were produced in 293 cells. CNE-2L2 cells were subcutaneously inoculated into nude mice. When tumors grew to 50-100 mm3, Ad5-siCD44 was injected into tumors, and Ad5-egfp and PBS were also injected as controls. The size and weight of tumors were compared after 2 weeks.

RESULTSSuppression of CD44 expression profoundly inhibited the malignant activities of CNE-2L2 cell. The average sizes of the tumors were (3.139 +/- 0.850), (3.612 +/- 0.888), and (1.512 +/- 0.742) cm3 after the intra-tumor injection of PBS, Ad5-egfp, and Ad5-siCD44, respectively, after two weeks. Significant difference was found between Ad5-siCD44 group and control groups (P < 0.05). The average weights were (2.28 +/- 0.73), (1.83 +/- 0.26), and (1.20 +/- 0.64) g, respectively, and significant difference was also found between Ad5-siCD44 group and control groups (P < 0.05).

CONCLUSIONIntra-tumor injection of Ad5-siCD44 can exhibit the therapeutic effect on the tumor inoculated with CNE-2L2 cells with high expression of CD44 in nude mice.

OBJECTIVETo study effects of ectopic expression of BCSC-1 gene on the malignant activi-BCSC-1 cDNA was isolated by RT-PCR ties of human nasopharyngeal carcinoma cell CNE-2L2.

METHODSand inserted into pMAL-c2X and pcDNA4/myc-His A. BCSC-1 protein was expressed in prokaryocytes. Rabbit antiserum to BCSC-1 was developed by means of immunization of rabbit with the BCSC-1 protein. Expression of BCSC-1 gene in wild type CNE-2L2 cell (W cell) was examined by real-time RT-PCR and immunofluorescence staining with the antiserum as a probe. pcDNA4/myc-His A-BCSC-1 was transfected into W cell at the presence of LipofectAmine. The cells were selected by G418 and cloned. Ectopic expression of BCSC-1 gene in W cell was examined by Western blot. Cell growth was detected by drawing of growth curves and colony formation tests. Cells were inoculated into nude mice. Size of tumors was assayed once a week. Lungs of the mice were sectioned continuously and metastatic loci in lungs were examined upon a microscope.

RESULTSRabbit BCSC-1 antiserum was prepared. Expression of BCSC-1 gene in W cell was found to be very low. CNE-2L2 cell with ectopic expression of BCSC-1 gene was developed. Growth in vitro, colony formation, tumorigenesis in nude mice, and lung metastasis of the tumor were profoundly inhibited of the cell with ectopic expression of BCSC-1 gene in comparison with controls, wild type cell and the cell transfected with mock. Conclusion Ectopic expression of BCSC-1 gene exerts profound inhibitive effect on the malignant activities of CNE-2L2 cell.

OBJECTIVETo analyze the nature of the protein encoded by 8B7cDNA (1 835 bp) and to examine the localization of the protein in cells.

METHODSThe nature of the protein was analyzed using Blastn, Blastp, and TMpred. Expressions of 8B7 mRNA in tissues and cells were examined by Northern blotting. Recombinant expression vectors for localization test were constructed and transfected into COS-7 cells. Fluorescence emission in cells was examined upon a laser scan confocal microscope.

RESULTSThe protein encoded by 8B7cDNA was 363 amino acids long and contained spectrin repeats. It was completely homologous to the C-terminal 363 amino acids of Enaptin, Nasprin-1, Mynel, and Syne-1 proteins. It belonged to Spectrin super-family and was called 8B7 spectrin. Northern blotting revealed a 1.8 kb mRNA expression in human spleen and small intestine tissues. EGFP-8B7 fusion protein was observed to express on the nuclear membrane and in the cytoplasm in a reticular form in a localization assay on COS-7 cells. The position of fluorescence in COS-7 cells transfected with pEGFP-delta SR8B7 was similar to that in the cells transfected with pEGFP-8B7cDNA.

CONCLUSIONS8 B7 spectrin is a novel member of spectrin super-family. It localizes to the nuclear membrane and the cytoplasm in a reticular form in COS-7 cells. The localization is determined by the C-terminal KASH domain in 8B7 spectrin molecule.

OBJECTIVETo study mechanisms of reduction of the malignant activities of human naso-pharyngeal carcinoma cell CNE-2L2 induced by ectopic expression of BCSC-1 gene.

METHODSDNA was stained with propidium iodide and assayed upon a flow cytometer. Chromosomes were stained with Hoechest 33258. Adhesion of CNE-2L2 cells was detected by cell aggregation test. Protein expression on CNE-2L2 cells was examined by Western blot.

RESULTSCell cycle analysis showed that the percentage of CNE-2L2 cells was 55.1%, 43.4%, and 39.4% in G0/G1 phase, 25.2%, 28.7%, and 30.9% in S phase, and 19.7%, 27.9%, and 29.7% in G2/M phase for the cell with ectopic expression of BCSC-1 gene, wild type cell (W cells), and the cell transduced with the mock (M cell). Many mitotic cells were found in W cells and M cells. In contrast, almost no mitotic cell was observed in the cells with ectopic expression of BCSC-1 gene. Ectopic BCSC-1 expression resulted in cell aggregation, enhanced expression of E-cadherin, cx-catenin, and p53.

CONCLUSIONSEctopic BCSC-1 expression causes enhancement of adhesion of CNE-2L2 cells associated with enhanced expression of E-cadherin and alpha-catenin, arrest of cell in G1 phase, which may be associated with enhanced expression of p53. These alteration may play a role in the reduction of malignant activities of the cells with ectopic expression of BCSC-1 gene.
