RESUMEN
Cortex Periplocae Radicis(CPR)is the dried root barks of Periploca spium Bge. It has been used in China for treat?ing rheumatoid arthritis and strengthening the bone and the musculature for thousands of years. Recently,an increasing number of bio?activities of CPR have been recognized,including tumor suppression and anti-chronic heart failure function. However,long-term use or large doses of CPR may produce adverse reactions,which constrains its applications in clinical therapy. Therefore,it is critical to know the chemical components of CPR in order to understand the toxicity mechanism. Nearly a hundred chemical compositions have been found,however,various classes,obfuscated names of different compounds,and disaccord between chemical structure and name were major obstacles to studying pharmacodynamics and toxicity of CPR. In this paper,94 chemical components of CPR are classified and reviewed,which is valuable for the comprehensive understanding of its biological functions and safe clinical use.
RESUMEN
Objective To evaluate the efficacy of transarterial chemoembolization (TACE) and percutaneous cryosurgery sequential therapy for unresectable hepatocellular carcinoma (HCC).Methods Four hundred and twenty patients with unresectable HCC were divided into sequential TACE-cryosurgery sequential (sequential) group (n=290) and cryosurgery alone (cryoalone) group (n = 130). TACE was performed with the routine operation; the percutaneous cryosurgery was conducted 2 to 4 weeks after TACE. The patients were followed up at the first month and once every 2 to 3 month later. Liver ultrasound or both computer tomography and alpha fetal protein were examined during follow-up. Results During a mean follow-up of (42±17) months (range from 24 to 70 months), the local recurrence rate of ablated lesion was 17% for all the patients, 11% and 24% for patients in sequential group and cryoalone groups respectively (P=0. 001). The overall 1-, 2-, 3-, 4-and 5-year survival rate was 72%, 57%, 47%, 39% and 31%, respectively. The 1- and 2-year survival rates (71% and 61 % ) in sequential group were similar to those (73 % and 54 % ) in cryo-alone group (P=0.69 and 0. 147), while the 4- and 5-year survival rates were higher in sequential group (49 % and 39 % ) than those (29 % and 23 % ) in cryo-alone group (P= 0.001). Eighteen patients with large HCC (＞5 cm in diameter) in sequential group survived for more than 5 years while no one in cryo-alone group. Complication rate was 24% in all patients, 21% and 26% for the sequential and cryo-alone groups respectively (P=0. 06). The incidence of hepatic bleeding was higher in cryo-alone group than in sequential group (P=0. 02). Liver crack occurred in two patients of the cryoalone group. Conclusions Pre-cryosurgical TACE increased the cryoablation efficacy and decrease its complications, especially hepatic bleeding. TACE and cryosurgery sequential therapy may be a better treatment for unresectable HCC, especially for large HCC.
RESUMEN
Objective To investigate the effects of component combination in Siwu Decoction (CCSWD) on the proliferation of human bone marrow stromal cell lines HFCL and hematopoiesis-related gene expression and to probe into the mechanism of the stimulative effects of SWD and CCSWD on the proliferation of HFCL cells. Methods MTT and FCM were used for assaying the proliferation potency and cell cycle of HFCL cells, respectively. A human hematopoiesis-related cytokine oligonuleotide microarray was prepared to investigate the diversity of gene expression of HFCL cells in SWD and CCSWD groups. Results The energy metabolism and proliferation potency of HFCL cells treated with CCSWD were more prompted than that of the control group. Meanwhile, the percentage of HFCL cells in G 0/G 1 phase treated with CCSWD was significantly lower, while the proliferation index (PI) was higher than that of the control group. Compared to the control group, expressions of IL 2-R?, NF-?B, and TPO were up-regulated in CCSWD group.Conclusion The proliferation of HFCL cells could be facilitated by CCSWD with up-regulating the expressions of IL 2-R?, NF-?B, and TPO.
