Objective Soft and hard channel minimally invasive interventions for patients with hypertensive intracerebral hemorrhage have been used for many years. A retrospective study was performed to evaluate the superiority of these two methods. Methods 122 patients with hypertensive intracerebral hemorrhage were included in this retrospective study, 64 cases in soft channel group and 58 cases in hard channel group. The clinical effects were compared; catheter retention time and complications of the minimally invasive surgery were also observed in these two groups. Results In soft channel group, NIHSS before the treatment was 18.05±7.77, and NIHSS after the treatment was 7.57±4.68. The mortality was 17.19%. The catheter retention time in hematoma puncture was (4.35±1.56)days, and the catheter retention time in ventricle puncture was (7.67±2.37)days. There were 4 cases of rebleeding and 3 cases of intracranial infection. In hard channel group, NIHSS before the treatment was 18.38±9.02, and NIHSS after the treatment was 8.02±4.84. The mortality was 20.69%. The catheter retention time in hematoma puncture was (4.07±1.49)days, and the catheter retention time in ventricle puncture was (8.17±2.55)days. There were 9 cases of rebleeding and 2 cases of intracranial infection. The differences were not statistically significant (P>0.05). Conclusions Soft and hard channel minimally invasive interventions of hypertensive cerebral hemorrhage have the same clinical value.

α-Hederagenin (H), derived from Hedera nepalensis var.sinensis, is a pentacyclic oleane-type triterpenoid that exhibits clear cytotoxicity to different tumor cell lines.In this study,a series of novel C-28 derivatives of hederagenin (H) were designed and synthesized in attempt to develop potent tumor resistance reverse activities agents. Previous research showed that H6 displayed robust reverse activity for paclitaxel resistance in KBV cells. Importantly, Co-treatment of paclitaxel with H6 significantly reduced the tumor weight to 42%. Pleasingly, H6 enhanced the efficacy of paclitaxel against KBV cancer cell-derived xenograft tumors in nude mice.Mechanism studies had found that H6 activated permeability glycoprotein(P-gp)ATPase,reduced intracellular ATP levels and inhibited efflux of P-gp substrates,thus enhancing the antitumor activity of paclitaxel on KBV cells.Molecular docking analysis of homology P-gp and H6 then conducted using the Surflex-Dock module.H6 showed a high binding affinity docking score with a total score of 5.4148,much higher than that of H(0.1414).The nov-el C-28 derivatives of H was synthesized from H6 via three-step reaction. The reversal activity of all synthesized H derivatives were tested using the MTT assay.The results showed that the derivatives of nitrogen groups at C-28 displayed same even potent activity than parent compound H6.In addition,its underlying mechanism of action and in vivo activity are in explore.

Aim To compare the inhibition of lipid peroxidation of ethyl acetate extract( EAE) and n-buta-nol( BE) extract from Coreopsis tinctoria Nutt. in vitro. To investigate the parameters such as body weight, bio-chemical indexes in plasma, and viscera indexes on type 2 diabetes mice by intraperitoneal injection of streptozotocin ( STZ ) . Methods The extracts were prepared by response surface methodology. The ex-tracts were suspended in distilled water and defatted with petroleum ether. The aqueous layer was succes-sively extracted with ethyl acetate and n-butanol. The inhibition of lipid peroxidation activity was determined by thiobarbituric acid method. The effects of extract BE on diabetic mice were observed at the dosage of 0. 2,0. 4,0. 8 g·kg-1 ( ig) for 4 weeks. The parame-ters were observed such as weight of body changes, or-gan coefficients of liver, pancreas and kidney, bio-chemical indexes in plasma and viscera pathological sections. Results In the linoleic acid reaction system, the SC50 value of the EAE and BE was ( 443. 96 ± 11. 24) mg·L-1, (840. 29 ± 16. 38) mg·L-1, re-spectively, and that in rat liver homogenate was (23. 59 ± 3. 67 ) mg · L-1 , ( 60. 37 ± 4. 27 ) mg · L-1 , respectively. Compared with diabetic model group, BE could significantly improve the trend of weight loss, and increase viscera indexes. The patho-logical sections showed that BE had the recovery and improvement effects on the damage of liver, pancreas and kidney. Conclusions The extracts of C. tinctoria have a certain anti-lipid peroxidation activity in vitro. And BE has a certain capacity to improve and repair damaged organs for DM mice.
