This study aims to investigate the effect of total flavones of Fructus Chorspondiatis (TFFC) on the mRNA and protein expression of collagen type I and III of rat cardiac fibroblasts (CFs) induced by angiotensin II (Ang II), and explore its anti-myocardial fibrosis molecular mechanism. Neonatal rat CFs were prepared from Sprague-Dawley rats (1-3 d after birth). The expression of collagen type I and III mRNA and protein were measured by RT-PCR and Western blotting, respectively. The study showed that stimulation of neonatal rat CFs with 100 nmol.L-1 of Ang II for 72 h resulted in a significant increase of the expression of collagen type I and III mRNA and protein. The changes on the expression level were blocked by TFFC. The results demonstrated that TFFC can inhibit myocardial fibrosis induced by Ang II in rats, which is probably associated with the collagen type I and III mRNA and protein levels up-regulated by Ang II, and TFFC was shown to decrease the expression levels of collagen type I and III mRNA and protein.

OBJECTIVETo investigate the protective effect and action mechanism of petroleum ether extracts from Saussurea involucrate on brain tissues of hypoxia rats under constant pressure and closed conditions.

METHODThe PESI dosage-dependent experiment for hypoxia rats was conducted under constant pressure and closed conditions by intraperitoneally injecting 125, 250, 500 mg x kg(-1) to finalize that the optimum dosage is the high dose of PESI. Afterwards, 90 Wistar rats were randomly divided into the hypoxic model group, the acetazolamide 250 mg x kg(-1) group and the PESI high dose group. Each group was further divided into three subgroups according to different hypoxia times, with 10 rats in each subgroup. Under the same hypoxia and administration conditions, the rats were sacrificed after 0, 3, 6 h respectively. Their brain samples were collected for common pathological observation and immunohistochemical staining of HIF-1alpha. Real-time RT-PCR was used to detect HIF-1alpha, EPO, HO-1 and Caspase-3 gene expressions. And the Western blot assay was adopted to detect HIF-1alpha protein expression.

RESULTThe brain tissues of the hypoxia model group were severely damaged with the increase in the hypoxia time. The acetazolamide group and the PESI high does group were damaged in a much lower degree. According to the gene expression and the Western blot assay, high dose of PESI could inhibit HIF-1alpha expression. According to the pure gene expression test, high dose of PESI could increase EPO and HO-1 mRNA expressions, but inhibit Caspase-3 mRNA expression.

CONCLUSIONPESI's protective mechanism for brain tissues of hypoxia rats under constant pressure and closed conditions may be related to its effects in inhibiting HIF-1alpha expression, increasing EPO expression and resisting cell apoptosis.

OBJECTIVETo explore relationship between volume of bone cement injection and concurrent of fracture after thoracolumbar osteoporotic vertebral fracture treated by percutaneous kyphoplasty (PKP).

METHODSFrom January 2006 to December 2008,68 patients with thoracolumbar osteoporotic vertebral fracture treated by PKP were retrospectively analyzed. Among them, 30 patients with less than 3 ml bone cement injection (mean 2.5 ml, low group), including 11 males and 19 females, with an average age of (85.0 +/- 8.5) years (ranging for 60 to 91); 38 cases with over 4 ml bone cement injection (mean 4.5 ml, large group), including 15 males and 23 females,with an average age of (86.0 +/- 9.2) years (ranging for 60 to 93). Factors of concurrent vertebral fractures were observed during follow-up.

RESULTSAll patients were followed up from 3.4 to 5.1 years with an average of 3.8 years. Thirteen patients (43.3%) co-occurred fracture in low group,among which strengthened concurrent vertebral fracture occurred in 1 case,upper and lower section adjacent vertebral fracture in 8 cases,distal segment of vertebral fracture in 4 cases; while 18 patients (47.3%) co-occurred fracture in large group,among which strengthened concurrent vertebral fracture occurred in 2 cases, upper and lower section adjacent vertebral fracture in 10 cases,distal segment of vertebral fracture in 6 cases. No significant difference between two groups (P > 0.05).

CONCLUSIONBone cement injection is not main influence factors for treating concurrent of fracture after thoracolumbar osteoporotic vertebral fracture by PKP. Concurrent fracture mainly relates with progress of osteoporosis, the volume of injection volume may appropriately over the volume of balloon.
