Advances in Molecular Targeted Drugs for Hepatocellular Carcinoma / 中山大学学报(医学科学版)

Being the most common solid malignant tumor in the digestive system and the third leading cause of cancer-related death worldwide， hepatocellular carcinoma （HCC） is characterized by insidious onset， early recurrence/metastasis and poor prognosis. With the advantages of targeted precision， high specificity， minimal drug resistance， remarkable therapeutic efficacy and fewer side effects， molecular targeted drugs have become the hotspot and focus of tumor therapy research in recent years. As more is learned about the mechanism and clinical efficacy， some molecular targeted drugs have been recommended by HCC treatment guidelines. This paper reviewed the mechanism of HCC targeted therapy， molecular targeted drugs， relevant therapeutic protocols and outcomes so as to provide reference and evidence for subsequent research.

Study on the therapeutic effect of electroacupuncture on migraine and influencing factors / 中国针灸

<p><b>OBJECTIVE</b>To compare therapeutic effects of electrical acupuncture (EA) at Qiuxu (GB 40) and Tianshu (ST 25), and to probe the factors of influencing the therapeutic effect.</p><p><b>METHODS</b>Two hundred and seventy-five cases were randomly divided into the test group of 138 cases treated with EA at Qiuxu (GB 40) and the control group of 137 cases treated with EA at Tianshu (ST 25). Their therapeutic effects were observed and the factors influencing the therapeutic effect were analyzed.</p><p><b>RESULTS</b>The transient effective rate was 70.3% in the test group and 58.4% in the control group with a significant difference between the two groups (P<0.05), and there were very significant differences between the two groups in the therapeutic effects at treatment of 4 weeks, and following-up 3 and 6 months later (P<0.001), the transient analgesic effect of EA at Qiuxu (GB 40) being better. EA had better transient effect on migraine for the mental workers, or the patient with high pain score at treatment, or more frequent attack. The long-term analgesic effect of EA at Qiuxu (GB 40) was better than Tianshu (ST 25).</p><p><b>CONCLUSION</b>The analgesic effect of EA at Qiuxu (GB 40) is better than Tianshu (ST 25) and the profession and conditions of the patient are the factors influencing the therapeutic effect.</p>

Kappa-opioid receptor stimulation contributes to aortic artery dilation through activation of K(ATP) channel in the rats / 生理学报

To investigate the relaxation effect and underlying mechanism of U50,488H (a selective kappa-opioid receptor agonist) on aorta in the rat, isolated aortic ring was perfused and the tension of the vessel was measured. It was shown: (1) kappa-opioid receptor stimulation with U50,488H relaxed rat aorta dose-dependently; (2) the relaxation effect of U50,488H on aorta was partially endothelium-dependent; (3) the relaxation effect of U50,488H was significantly attenuated in the presence of glybenclamide and glipizide, two ATP-sensitive K(+) channel (K(ATP)) blockers; and (4) the relaxation effect of U50,488H on vessel bore no relationship to muscarinic-receptor, beta-adrenoceptor, prostaglandin and nitric oxide (NO). These results indicate that kappa-opioid receptor stimulation with U50,488H relaxes the aortic artery at least partially via K(ATP) channel in the rat.
