OBJECTIVE: To investigate the regulating pattern of kidney-tonifying recipes and spleen-invigorating recipe on the expression of T lymphocyte apoptosis signaling-related genes in corticosterone-treated rats. METHODS: We analyzed the activation-induced T lymphocyte apoptpsis rate through TUNEL-labelled flow-cytometry assay, quantified the mRNA expression level of T cell apoptosis-regulating genes by using the fluoresecence real-time PCR, analyzed the activity of caspase-8 and caspase-3 by colorimetric assay. RESULTS: (1) T lymphocyte apoptosis rate of corticosterone-treated rats was higher than that of the normal control rats; T lymphocyte apoptosis rates of Youguiyin treated rats and Bushen Yishou Capsule treated rats were lower than that of the corticosterone-treated group; T lymphocyte apoptosis rate of Sijunzi Decoction treated rats displayed no significance compared with that of the corticosterone-treated group. (2) Pro-apoptotic genes such as Fas, FasL, TNFR1, and Bax displayed increased expression level in corticosterone-treated group compared with normal control group. Two kidney-tonifying recipes down-regruated the expression level of FasL and TNFR1, at the same time, both recipes up-regulated the expression level of Bcl-2. The spleen-invigorating recipe had up-regulating effect on the expression level of Bcl-2. And all these results had statistical significance. (3) The activities of caspase-8 and caspase-3 were increased in corticosterone-treated rats compared with normal control; both kidney-tonifying recipes had significant effect on decreasing the activities of these two apoptosis executioners. CONCLUSION: The excessive apoptosis of T cell in corticosterone-treated rats could be effectively modulated with two kidney-tonifying recipes. Down-regulating the expression of FasL and TNFR1 and up-regulating the expression of Bcl-2 as well as decreasing the activities of caspase-8 and caspase-3 may be the unique regulating pattern of tonifying-kidney method with respect to T cell apoptosis related genes in corticosterone-treated rats.

Objective To explore the possible mechanism of the apoptosis of hepatoma cell line HepG2 induced by the combination use of GNRs@SiO2-FA and 125I seeds and to discuss its relationship with Bcl-2 and Bax protein expressions so as to provide theoretical basis for clinical treatment of hepatic cancer with interstitial brachytherapy by using 125I seeds. Methods In vitro cultured HepG2 cells were randomly divided into 4 groups: blank control group (not treated), simple GNRs@SiO2-FA group, simple 125I seeds group, and combination group (GNRs@SiO2-FA plus 125I seeds). The apoptosis of HepG2 cells was determined by flow cytometry. The expression of Bax mRNA and Bcl-2 mRNA of HepG2 cells were tested by RT-PCR. The apoptosis-related genes (Bax and Bcl-2) and the tumor proliferation cell nuclear antigen (Ki67) proteins expression on HepG2 cells were examined with immunohistochemistry method. Results The flow cytometry examination showed that the apoptosis rate of HepG2 cells in the simple GNRs@SiO2-FA group and simple 125I seeds group was higher than that in blank control group (P<0.05), and the apoptosis rate of the combination group was significantly higher than that of the simple GNRs@SiO2-FA group and the simple 125I seeds group (P< 0.05). The expression level of Bax mRNA in the combination group was higher than that in the simple GNRs@SiO2-FA group and simple 125I seeds group, while the expression level of Bcl-2 mRNA in the combination group was obviously lower than that in the simple GNRs@SiO2-FA group and simple 125I seeds group. Bax protein was expressed on cytoplasm, Bcl-2 protein was expressed on cytoplasm and cell membrane, while Ki67 protein was expressed on nucleus. All of them presented as brown finely granular precipitations. Statistically significant differences in the amount of Bax, Bcl-2 and Ki67 protein expression existed between each other among the four groups (P< 0.05). The positive expression rate of Bax protein in the combination group was significantly higher than that of the simple GNRs@SiO2-FA group and the simple 125I seeds group, while the positive expression rate of Bcl-2 and Ki67 protein was significantly lower than that of the simple GNRs@SiO2-FA group and the simple 125I seeds group, and the differences were statistically significant (P < 0.05). Conclusion The combination use of GNRs@SiO2-FA and 125I seeds can more effectively induce the apoptosis of HepG2 cells. This effect may be accomplished through increasing the expression of Bax protein and inhibiting the expression of Bcl-2 and Ki67 proteins.

Objective To investigate the clinical efficacy of intravitreal injection of Lucentis combined with pan retinal photocoagulation and trabeculectomy for neovascular glaucoma(NVG). Methods Seventeen eyes of 15 patients with NVG were treated by 0.5 mg Lucentis intravitreal injection first. Trabeculectomy was performed 7 days later and Pan retinal photocoagulation 2 weeks later. Iris,anterior chamber angle neovascularization,intraocu?lar pressure ,and visual acuity were observed in the following 6 months. Results Iris and anterior chamber angle neovascularization were completely regressed 7 days after the injection in 17 eyes. Six months after photocoagulation, 6 eyes had different degrees of improvement in visual acuity,10 eyes no change in visual acuity and 1 eye decreased from anterior index to immediate manual. There was significant difference in pre?treatment IOP and postoperative IOP( t = 12.75 ,10.26 ,9.73 ,10.77 ,P < 0.01 ). No serious complications were observed after intravitreal injec?tion and trabeculectomy. Conclusions Intravitreal injection of Lucentis could significantly accelerate the regres?sion of iris and anterior chamber angle neovascularization ,which could improve the successful rate of trabeculecto?my and pan retinal photocoagulation. Intravitreal injection of Lucentis combined with trabeculectomy and panretinal photocoagulation is safe and effective for NVG.
