Objective Observe the effect of using ginseng and astragalus arbran decoction with western medicine on type-2 diabetes. Method Divide fifty type-2 diabetes sufferers into control group and treatment group randomly.Sufferers from control group take diformin tablets and acarbose orally; Those from treatment group take ginseng and astragalus arbran decoction additionally on that basis for eight weeks continuously.Compare the changes of blood sugar of the two groups before and after the treatments in the situation of limosis and two hours after dinner. Results control group and treatment group each has a total effective rate of 72% and 98% respectively, significant difference exists (P<0.05). Conclusion Using ginseng and astragalus arbran decoction with western medicine has a better effect on controlling blood sugar.

Benign and malignant compression fracture of vertebrae are common diseases in clinic. Because their therapies are different,it is important to identify them. At present, MRI is the main means in discriminating benign and malignant compression fracture of vertebrae. Sometimes the change of MRI signal in them is overlap, therefore, it is difficult to diagnose accurately. In the recent years, with the appearance of MRI new technology, people have already applied it to work out the difficulty.

Objective To construct a RhoC-siRNA expression vector, and study its role on the biological behaviors of hepatoma carcinoma cells. Methods RhoC-siRNA gene was synthesized and cloned into the expression vector pSilencer2.1. The constructed RhoC-siRNA expression vector was stably transfected into hepatoma carcinoma cell line SK-Hep1. The inhibitory effect of RhoC-siRNA on the expression of RhoC in transfected cells was detected by Western blotting. The morphous, growth velocity and the ability of cell adhesion, cell migration, cell invasion before and after transfection was observed. Results Enzyme digestion and DNA sequencing confirmed that the RhoC specific siRNA expression vector was constructed successfully. After transfection, RhoC expression was inhibited by 60%, and no marked difference was observed in cellular morphous and growth curve, while the ability of cell adhesion, cell migration, and cell invasion were markedly decreased. Conclusion The RhoC-siRNA expression vector can effectively suppress RhoC expression in transfected hepatoma carcinoma cells. Although having no effect on the morphous and growth velocity of hepatoma carcinoma cells, it decreases the potentiality of cell invasion and cell metastasis, which may provide a novel applicable strategy for gene therapy on hepatocellular carcinoma.

BACKGROUND:Tripterygium wilfordi and its certain monomers have exact clinical effects on rheumatoid arthritis. However, there are few studies about a systematic discussion on pharmacodynamic material basis and molecular mechanism of Tripterygium wilfordi. OBJECTIVE:To explore the pharmacodynamic material basis and molecular mechanism ofTripterygium wilfordi in treating rheumatoid arthritis. METHODS: Based on the platform of Discovery Studio 4.0, the molecular set of Tripterygium wilfordiwas built and compared with the rheumatoid arthritis drug set from Therapeutic Target Database in chemical space. After that, network pharmacology was used to explore the interactions ofTripterygium wilfordi and therapeutic targets related to rheumatoid arthritis. RESULTS AND CONCLUSION:The molecular sets ofTripterygium wilfordi and drugs for treating rheumatoid arthritis had similar chemical space. The pharmacodynamic material basis ofTripterygium wilfordi had 46 compounds, such as celacinnine, epigalocatechin, euonine, triptolide. They could mediate inflammation, regulate immune response, inhibit cartilage and bone destruction, improve blood stasis-type rheumatoid arthritis by acting on 10 targets, such as tumor necrosis factor-α, JAK-1, matrix metaloproteinase-1, matrix metaloproteinase-3, matrix metaloproteinase-9. Computer simulation could intuitively trace out the multi-ingredient, multi-target and multi-pathway effects of Tripterygium wilfordi.

Objective To study the effect of an immuno-targeted therapy drug Herceptin on apoptosis and cell cycle of overexpressing HER2 breast cancer cells.Methods Breast cancer cell line SKBR-3 was treated with Herceptin at most effective dosage and exposure time were selected by MTT assay.Then the apoptotic features,the apoptotic rate and the change of cell cycle of breast cancer cells were detected by fluorescent microscope(FM),laser confocal microscope(LCM),scanning electron microscope(SEM),transmission electron microscope(TEM)and flow cytometry(FCM).Results With the treatment of Herceptin,the visible apoptosis features of SKBR-3 cells were observed by FM,LCM,SEM and TEM.Compared to the control cell group,the rate of initial apoptotic cells detected by FCM with Annexin V/PI staining increased significantly(P

Objective To investigate the mechanism that BC047440 gene regulates nuclear fac-tor κB sigal passway and analyze the differential expression gene between HepG2 cells and HepG2 cells BC047440 gene silenced by RNAi using 35K Human Genome Array. Methods The differential expres-sion gene between HepG2 cells and HepG2 cells with BC047440 gene silenced was analyzed by 35K Human Genome Array, and the data were submitted to the database and MAS system of Capitalbio Corporation.Then TRAF6 was confirmed by RT-PCR test. Results Among the total 35000 probe sets, the expression of 59 genes was down-regulated for more than 50% and 130 genes were up-regulated more than 2 fold in the silencing group when compared with normal controls. TRAF6 mRNA was decreased for 29.5% in silicening HepG2 compared with that of wild HepG2 by RT-PCR, which is similar to human genome array(23.06%).Conclusion The high throughput and effective oligomicroarray can analyze the differential expression gene and BC047440 gene might regulate NF-κB signal pathway inderectly by TRAF6.

AIM: To investigate the protective effect of five natural anti-oxidants (schisandrin B, Sch B; silibinin, SIB; propyl gallate, PG; sodium ferulate, SF; total flavonoids of hippophase, TFH) on experimental oxidative injuries of lens. METHODS: All fresh transparent lenses of rabbit eyes except control group were bathed in Fenton reaction system in order to produce a model of oxidative damages of lens, meanwhile Sch B, SIB, PG, SF, TFH and pirenoxine sodium (PS) were added in the reaction system in different groups respectively. Lenses were incubated for 24 hours. Then total protein (TP), soluble protein (SP), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH), vitamin C (Vit C), total activities of anti-oxidation (TAO) and malondiaoldehyde (MDA) in homogenized lenses were measured to observe the effects of five anti-oxidants on above index. RESULTS: Five anti-oxidants increased the anti-oxidative index and decreased MDA in lens of oxidative damages in different levels, the effects are better than that of PS, especially in group SF and Sch B. CONCLUSION: The five natural anti-oxidants protected lens against experimental oxidative injuries very well. There are wide prospects to pursue effective anti-cataract drugs from natural anti-oxidants.

AIM: To investigate the effects of Co-SZ eye drop on galactose cataract in rats. METHODS: Based on folk remedy, SZ eye drop was made from leech, as a modified SZ eye drop, Co-SZ eye drop was enriched in Zinc and Vitamin C. In the present study, animal model of galactose cataract in SD rats was used. All animals were randomly divided into 3 groups : control group(using 0.9 % NaCl instead of SZ and Co SZ), SZ group and Co-SZ group. Lens opacities were examined dynamically in each groups via FS-3V slit-lamp microscope. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione (GSH) and soluble protein (SP) in the lenses were measured in 15 days. RESULTS: Both the Co-SZ and SZ eye drops could significantly delay and alleviate galactose cataract in rats, with better effect of Co-SZ than SZ eye drop. The antioxidant index indicated that SOD, GSH-Px, GSH in Co-SZ and SZ group were significantly higher than that in control group. Furthermore, SOD, GSH-Px in Co-SZ group were higher than that in SZ group significantly. CONCLUSION: Co-SZ eye drops could significantly delay and alleviate galactose cataract in rats, the effect is much better than SZ eye drops. The different effect between SZ and Co-SZ eye drops could be raised from the different content of Zinc, which is involved in anti-oxidation.
