OBJECTIVETo observe the clinical effect and the influences of Shuxuetong injection on serum neuron-specific enolase (NSE) level, the neurological deficit and activities of daily living in patients with acute cerebral infarction.

METHODThe 80 patients with acute cerebral infarction were randomly divided into Shuxuetong treatment group (40 cases) and routine control group (40 cases), both received routine treatment, while Shuxuetong injection was given additionally to treatment group. The serum NSE level, the National Insitute of Health Stroke Scale (NIHSS) scores and the clinical effect were observed pre-and post-treatment. The Barthel Index (BI) was evaluated after one month.

RESULTThe serum NSE level and NIHSS scores in two groups of post-treatment decreased obviously than those of pre-treatment, and after treatment in Shuxuetong treatment group the serum NSE level and NIHSS scores were significantly lower than those in control group, the differences were significant (P<0.05). Effective rate of Shuxuetong treatment group was 87.5%, and control group was 65%, the difference of the clinical effect between the two groups was significance (P<0.05). After one month BI of post-treatment in two groups improved than those of pre-treatment, and Shuxuetong treatment group was significantly better compared with control group (P<0.05).

CONCLUSIONShuxuetong injection has the remarkable neuronal protective effect, can decrease the serum level of NSE after acute cerebral infarction, promote recovery of nerve function, reduce disability rate, and improve quality of life and prognosis of patients with acute cerebral infarction.

Background and objective 50%-70%of patients with advanced lung cancer will develop bone metas-tases. hTe aim of this study is to establish the nude mice bone metastasis model of lung adenocarcinoma using A549, H1299, SPC-A-1 and XL-2, all of which own different invasion and migration abilities in vitro and supervise the bone metastases by MicroCT. Methods iftfy BALB/C-nu/nu nude mice were grouped into ifve groups on average randomly. Cells of the four cell lines were injected into the letf cardiac ventricle of mice in the four experimental groups (0.2 mL/mouse) respectively;meanwhile, mice in the control group were injected with normal saline (0.2 mL/mouse) in the same manner. Periodical radio-logical examination was carried out to supervise the variation of the mice since the second week atfer injection. When mice in each group became thin obviously, end the experiment of this group. Before the end, pathological sections of bone tissues were made. We classiifed the bone metastatic sites into axial skeleton and limb bone, in order to compare the metastatic rates of these two different parts. hTe bone metastatic abilities of the four cell lines was statistically analyzed by comparing the average time cost in the appearance of bone metastases and the percentage of bone metastases among the experimental groups. Results Different metastatic sites which had been identiifed both by MicroCT and pathological sections appeared in each group of the four experimental groups. By contrast, no metastasis was observed in the control group. hTe percentage of cancer metastasiz-ing to axial skeleton was remarkably higher than the percentage of tumor metastasizing to the limb bone in each experimental group, which was consistent with the clinical regularity and characteristics of skeletal metastases with lung cancer. hTus, the model has been established triumphantly. However, there were no statistical differences in the average time consumed and skeletal metastatic rate among the four experimental groups. Conclusion hTe disruption in the bone can be clearly detected by MicroCT, which is beneift to supervise the osseous metastasis. We successfully developed the nude mice bone metastasis model of lung adenocarcinoma, which will pave the way for exploring novel prevention and therapy strategies clinically. hTe four cell lines varied in invasion and migration abilities in vitro, but there was no statistical difference in the metastatic ability in vivo, and the reason need to be explored further in future.
