1.Observation on the Effect of Treatment of Advanced Stage of Cancer of Colon by Integrated Chinese and Western Medicine: Report of 260 Cases
Journal of Traditional Chinese Medicine 1993;0(04):-
Conventional therapy was given to 260 cases of advanced stage of cancer of colon during the period of 1975 - 1988. Radical operation, palliative resection or changing bowel passage were selected according to the condition of the lesions. Post operative chemo -therapy with integrated Chinese and western medicine were given, or with radiotherapy in some of the cases. Results showed that the 5- year survival rates of II, III, IV stages were 80. 5%, 56. 12%, 21. 73% respectively, the mean 5 -year survival rate being 52. 78%, 45 cases with liver metastasis were also treated with integrated medicine with a 5 - year surivial rate of 22. 2%. The above figures of therapeutic effect and survival rates were all superior to that in cases treated by western medicine alone as reported by domestic exponent units.

Aim To investigate the effects of Zhiling capsule (ZLJN) on the proliferation inhibition and apoptosis induction in K562 cell line.Methods According to the different components of ZLJN,K562 cells were treated respectively with tradtional Chinese medicine,Western medicine and ZLJN compound groups.The cell viability and colony formation were observed by MTT assay and colony formation assay respectively.Apoptotic cells were detected by Annexin V-FITC/PI staining and DNA fragmentation assay.Caspase-3 activity was detected by flow cytometry,and pro-caspase-3 was detected by Western blot.Results Treated with drug,K562 cell growth and cell colony formation were significantly inhibited.Apoptosis occurring in the early stage was identified by Annexin V-FITC/PI staining.Typical DNA ladder was seen from gel electrophoresis and apparent apoptotic peaks were observed by flow cytometer.The level of caspase-3 activity increased after the treatment,while the level of pro-caspase-3 decreased.Conclusion ZLJN can efficiently inhibit proliferation and induce apoptosis in K562 cells,which may be related with the up-regulation of caspase-3 activity.

The extremely low bioavailability of oral paclitaxel (PTX) mainly due to the complicated gastrointestinal environment, the obstruction of intestinal mucus layer and epithelium barrier. Thus, it is of great significance to construct a coordinative delivery system which can overcome multiple intestinal physicochemical obstacles simultaneously. In this work, a high-density PEGylation-based glycocholic acid-decorated micelles (PTX@GNPs) was constructed by a novel polymer, 9-Fluorenylmethoxycarbonyl-polyethylene glycocholic acid (Fmoc-PEG-GCA). The Fmoc motif in this polymer could encapsulate PTX via π‒π stacking to form the core of micelles, and the low molecular weight and non-long hydrophobic chain of Fmoc ensures the high-density of PEG. Based on this versatile and flexible carriers, PTX@GNPs possess mucus trapping escape ability due to the flexible PEG, and excellent intestine epithelium targeting attributed to the high affinity of GCA with apical sodium-dependent bile acid transporter. The in vitro and in vivo results showed that this oral micelle could enhance oral bioavailability of PTX, and exhibited similar antitumor efficacy to Taxol injection via intravenous route. In addition, oral PTX@GNPs administered with lower dosage within shorter interval could increase in vivo retention time of PTX, which supposed to remodel immune microenvironment and enhance oral chemotherapy efficacy by synergistic effect.
