Inhibitory effect of Shenci capsule in combination with DDP on angiogenesis in mice with Lewis lung cancer

AIM: To investigate the inhibitory effect of Shenci capsule, a Chinese medicine, in combination with cisplatin (DDP) on the tumor growth and angiogenesis in mouse Lewis lung cancer.METHODS: Forty mice with Lewis lung cancer were randomly divided into 4 groups: Shenci capsule group, Shenci capsule in combination with DDP group, DDP group and control group. Shenci capsule, Shenci capsule in combination with DDP,DDP and sodium chloride wene given, respectively. After 21 days, the weight of subcutaneous tumors was measured, and the tumor inhibition rate was calculated. The microvessel density (MVD) and the protein level of vascular endothelial growth factor (VEGF) were detected by immunohistochemical(IHC) staining. The mRNA expression levels of kinase insert domain-containing receptor (KDR) and the receptor of VEGF were detected by FQ-PCR. RESULTS: The tumor growth inhibitory rate in Shenci capsule in combination with DDP group (63.99%) was higher than that in Shenci capsule group, DDP group and control group (P<0.01). The tumor MVD, VEGF protein and KDR mRNA expression level in Shenci capsule in combination with DDP group were lower than those in the above three groups (P<0.01). CONCLUSION: Shenci capsule in combination with DDP have addition or synergistic effects to inhibit the tumor growth and angiogenesis in mouse Lewis lung cancer. Down-regulation of VEGF and its receptor KDR may be one of the mechanisms that combined use of these two drugs for inhibiting angiogenesis.

Larval instars determination for the European Grapevine Moth (Lepidoptera: Tortricidae) based on the frequency distribution of head-capsule widths

Morphological measurements such as head-capsule (HC) width can be very useful and accessible tools that may be employed for classifying Lepidopteran larval instars according to stage of life history. The availability of such measures is crucial in the management of larval pests, because their control relies upon making accurate assessment of the life history stage at which larvae has reached in various environmental conditions. Such forecasts are then used in order to estimate the timing of emergence for future adult populations. Previous studies investigated the use of head-capsule widths from field larvae of European Grapevine Moth (EGVM), Lobesia botrana Den. and Schiff., to describe the distributions of the five instars during three generations of the insect. The observations were performed in 1998 and 2002 in a vineyard near Bordeaux. The results presented here increase the scope of earlier methods by providing statistical confidence. Our method was calibrated on a large number of individuals (N = 552) issued from our insect culture and uses a nonlinear least-squares parameter estimation to describe the distribution of each larval instar inside each generation. The model was tested on a wild larval population (n = 3007) occurring in our experimental vineyard during two complete years. The instar class ranges and boundaries were characterized with the associated probabilities of misclassification. A final classification statistical model is developed for each instar and each generation. From this study, we conclude that larval HC sizes increase statistically according to the generation of the year, and thus is influenced by grape phenology.
