In this paper, we extend the multiple Riccati equations rational expansion method by introducing a new ansatz. Using this method, many complexiton solutions of the (2+1)-dimensional Nizhnik-Novikov-Veselov equations are obtained which include various combination of hyperbolic and trigonometric periodic function solutions, various combination of hyperbolic and rational function solutions, various combination of trigonometric periodic and rational function solutions, etc. The method can be also used to solve other nonlinear partial differential equations.

AIM: To study the inhibitory effects of a Shuangling Fuzheng anticancer preparation (SFAP) on the human gastric cancer cell line SGC-7901 in vitro as well as its immune-modulated effects in a cyclophosphamide-treated murine model. METHODS: MTT experiments and immunocytochemistry ABC experiments were performed for detecting the proliferation of SGC-7901 cells in vitro and protein expression of c-myc. The staphylococcal protein A (SPA) rosette test was utilized for measuring the ratio of T-lymphocyte subsets from peripheral blood in a cyclophosphamide-treated murine model. Enzyme- linked immunosorbant assay (ELISA) was performed for measuring the levels of serum sIL-2R in treated mice, while immunoturbidimetry was used for measuring the levels of immunoglobulins (Ig). RESULTS: SFAP (40-640 mg/L, 48 h) inhibited the proliferation of SGC-7901 cells, and a positive correlation was noted between inhibitory effects and dosage. At a dosage of 160-320 mg/L in cultured cells, the expression of c-myc was decreased. SFAP (50-200 mg/kg) increased the percentage of CD3+ and CD4+ T-lymphocytes, the ratio of CD4/CD8, and the contents of Ig such as IgM, IgG or IgA, but decreased the levels of serum sIL-2R in peripheral blood from cyclophosphamide-treated mice. CONCLUSION: SFAP can inhibit the proliferation of SGC-7901 cells via the c-myc gene. In addition, SFAP can modulat the cellular and humoral immunity in cyclophosphamide-induced immunosuppressed mice.

Professor Jiping ZHAO has unique thoughts on the diagnosis and treatment of peripheral facial *** pays the great attention to clinical differentiation in treatment with acupuncture, especially meridian differentiation. She believes that the differentiation of lesion is core and the early judgment is critical for the better therapeutic effects on intractable facial paralysis. The local acupoints are selected in the guide of the theory of meridian sinew and stimulated on the base of three-needling theory. The distal acupoints are decided in light of the syndrome differentiation, of which, Hégǔ(合谷 LI 4), Zúsānlǐ(足三里ST 36) and Taichōng(太冲 LR 3) are the basic acupoints. Additionally, Professor ZHAO lays the emphasis on the 5 th branch of facial nerve(cervical branch) in diagnosis and treatment.

The modified Cry1Ac was expressed in transgenic tobacco plants. To allow secretion of the Cry1Ac protein into the intercellular space, the signal peptide sequence of potato proteinase inhibitor II (pinII) was N-terminally fused to the Cry1Ac encoding region. Expression of Cry1Ac in transgenic tobacco plants was assayed with ELISA. The results showed that pinII signal peptide sequence enhanced the expression of Cry1Ac protein and led to the secretion of the Cry1Ac protein in transgenic tobacco plants. GFP gene was also fused to the signal peptide sequence and transformed to tobacco. The results of fluorescent detection showed that GFP had localized in the apoplast of transgenic plants.
