ABSTRACT
Professor LI Zhi-dao, according to acupoint selection of syndrome differentiation in TCM basic theory, concluded a new therapy, namely "tonifying three qi" that is mainly based on three acupoints in the Conception Vessel. This method is consisted of Danzhong (CV 17), Zhongwan (CV 12) and Qihai (CV 6) in the Conception Vessel, which could successively nourish clear qi, stomach qi and original qi. In clinic, according to the severity of symptoms of three qi, the acupoints are selected flexibly, which could respectively treat deficiency of heart-lung qi, deficiency of stomach-spleen qi and deficiency of original qi. Some examples are also given in the article.

This study aimed to explore Semaphrin4D (Sema4D) expression and clinical significance in non-small cell lung cancer (NSCLC), and to define the roles and mechanisms of Sema4D in regulating the malignant behaviors of A549 cells by small interfering RNA (siRNA). Firstly, immunohistochemistry revealed that Sema4D was more frequently expressed in NSCLC than in lung benign lesion (P<0.05) and its overexprssion was associated with low differentiation (P<0.05), poor pTNM staging (P<0.05) and occurrence of lymph node (LN) metastasis (P<0.05). Endogenous Sema4D expression was suppressed by Sema4D siRNA in A549 cells overexpressing Sema4D. Protein levels of Sema4D, total Akt and p-Akt were examined by Western blotting. Cell proliferation, migration and invasion abilities were measured by MTT assay and Transwell assay respectively. Results showed that Sema4D siRNA significantly suppressed phosphorylation of AKT in A549 cells, but it did not alter total AKT expression. In addition, efficient down-regulation of SemaD significantly inhibit cell proliferation (P<0.05), migration (P<0.05) and invasion (P<0.05) in A549 cells. These findings suggest that Sema4D might serve as a reliable tool for early prediction of NSCLC poor prognosis. Sema4D could play an important role in promoting tumor proliferation, migration and metastasis in the NSCLC, by influencing the Akt protein phosphorylation. Inhibition of Sema4D may be a useful approach for the treatment of NSCLC.

<p><b>OBJECTIVE</b>To evaluate the efficacy and toxicity of palonosetron for prevention of vomiting induced by high dose cisplatin-based chemotherapy.</p><p><b>METHODS</b>One-hundred and twenty-eight patients received tropisetron 5 mg plus dexamethasone 10 mg at the first cycle or palonosetron 0.25 mg plus dexamethasone 10 mg, respectively, each administered 30 min before the initiation of high dose cisplatin-based chemotherapy. To observe the remission rate of acute emetic episodes and delayed emetic episodes, adverse effects and daily food-intake in the patients after the chemotherapy.</p><p><b>RESULTS</b>The complete response (CR) rates for acute vomiting were not significantly different between the tropisetron and palonosetron cycles (75.8% vs. 79.7%, P>0.05). The complete control rate of delayed vomiting in the palonosetron cycle was significantly higher than that in the tropisetron cycle (70.3% vs. 50.8%, P<0.01). The food-intake decrease rate of palonosetron cycle was 18.8%, significantly lower than the 53.1% of the tropisetron cycle (P<0.05). The toxicity in the two cycles was similar and no grade 3-4 toxicity was observed.</p><p><b>CONCLUSIONS</b>Palonosetron is superior to tropisetron with a lower remission rate of delayed emesis induced by high dose cisplatin-based chemotherapy and with tolerable toxicity. Moreover, the apparent emesis control of palonosetron treatment seems to provide an adequate food-intake in these patients.</p>
