Objective To investigate the expression and function of integrin-iinked kinase (ILK) in the transdifferentiation process of primary tubular epithelial cell( TEC) and its effect on the accumulation of extracellular matrix (ECM) in the aging process. Methods Primary TEC was cultured from kidneys of male Wistar rats aged 3 and 24 months. Then the primary TEC was stimulated by TGF-? at the concentrations of 0, 5, 10 and 20-40/?g/L for 24 h. The TEC expressions of ?-SMA,ILK and F-actin were detected by immunocytochemistry or indirect immunofluorescence. FN or ILK protein expression levels were tested by Western-blot. DIG-labelled cRNA probe of rat ILK in situ hybridization was obtained by transcription in vitro, with which ILK expression level and the location of TEC were detected. Results ?-SMA expression levels were very low in young or aging rat TEC on the base situation, no significant difference was found between the two groups. However, ILK and F-actin levels in 24 months group were higher than in 3 months group. Along with increasing concentration of TGF-?, ?-SMA, ILK and F-actin levels were increased. The expression of ILK was associated with F-actin expression. FN and ILK expression levels were significantly lower in 3 monthsrats TEC than in 24 monthsrats, P

1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.

OBJECTIVETo investigate the role of the expression of growth hormone receptor (GHR) in the development and progression of human colorectal cancer (CRC).
METHODSThe expression levels of GHR and Ki-67 were detected by immunohistochemistry technique in CRC specimens and normal mucous tissue from 100 patients with CRC. The association between expression of GHR and clinicopathological factors was analyzed.
RESULTSThe expression of GHR was higher in the colorectal cancerous tissue compared to the normal mucous tissue (81% vs. 68%). The expression of GHR was significantly correlated with pathological staging (P=0.047), tumor differentiation (P=0.003) and tumor size (P=0.017). The expression of GHR was significantly associated with the expression of Ki-67 (P< 0.01) as well as tumor proliferation (P< 0.01).
CONCLUSIONThe over-expression of GHR is shown in human colorectal cancer and it also plays an important role in the development of human colorectal cancer. The use of rhGH in clinic should be cautious.

OBJECTIVETo investigate the effect of preoperative radiotherapy as an adjunctive approach on proliferation and apoptosis of cancer cells in rectal cancer.
METHODSEighty patients with (p)TNM stage II or III rectal cancer were enrolled from April 2000 to December 2002. The patients were divided into two groups, which were group received surgical treatment alone (40 cases) and group received preoperative adjuvant radiotherapy with a radiological dose of 40 G( y ) (40 cases). The expression of Ki- 67 protein in rectal cancer was detected immunohistochemically and apoptosis was detected by TUNEL technique.
RESULTSIn radiotherapy group, the tumor volume shrank markedly in 14 cases, partially in 18,slightly in 8 with an overall efficiency rate of 80% .There was significant positive correlation between spontaneous apoptosis and Ki- 69 marker index in cancer tissues before radiotherapy(gamma =0.563P=0.027). The expression of Ki- 67 in rectal cancer tissues was significantly lower after radiotherapy than that before radiotherapy, as well as in the control group(P=0.017 vs. P=0.011).The expression of Ki- 67 in paratumor tissues 2cm from tumor was significantly lower after radiotherapy than that before radiotherapy. Apoptosis index (AI) in rectal cancer tissues was significantly higher after radiotherapy than that before radiotherapy, and that in the control group (P=0.013 vs. P=0.018).
CONCLUSIONRadiotherapy can inhibit proliferation and induce apoptosis of rectal cancer cells. The expression level of Ki- 67 can be considered as a screening index for preoperative radiotherapy.

BACKGROUND: Increasing evidence has indicated that low-concentration hydrogen or hydrogen rich water or hydrogen saturated saline exerts a protective effect on various diseases, such as myocardial ischemia/reperfusion injury. OBJECTIVE: To explore the protective effect of hydrogen rich water on myocardial ischemia/reperfusion injury. METHODS: Forty-eight Wistar rats were equally randomized into control and hydrogen-rich groups, and then subdivided into ischemic preconditioning, ischemia, and ischemia/reperfusion groups (n=8 rats in each subgroup). The myocardial ischemia/reperfusion model was established in the heart of each rat by the following procedures: reverse perfusion for 10 minutes, room temperature for 20 minutes, and reperfusion for 20 minutes. The control rats was perfused with pre-oxygenated (95% O2plus 5% CO2) 37 ℃ K-R solution and the hydrogen-rich group was perfused with pre-oxygen-equilibrated (95% O2plus 5% CO2) 37 ℃ K-R solution plus hydrogen-rich water (0.6 mmol/L, pH=7.3). Subsequently, the heart was removed, the pathological changes of the myocardial tissues were observe by hematoxylin-eosin staining, the activities of lactic dehydrogenase and creatine kinase in the myocardial tissues were determined, and the levels of tumor necrosis factor-α and interleukin-1β were detected by ELISA. RESULTS AND CONCLUSION: In the control group, the activity of lactic dehydrogenase at the ischemic and ischemia/reperfusion stages was significantly higher than that at the ischemic preconditioning stage (P < 0.05), and the activity of creatine kinase at the ischemia/reperfusion stage was significantly higher than that at the ischemic preconditioning and ischemic stages (P < 0.05). In the hydrogen-rich group, there was no significant difference in the activities of lactic dehydrodenase and creatine kinase at each stage, but the activities of at the ischemia/reperfusion stage was significantly lower than those in the control group (P < 0.05). In the two groups, the order of the levels of tumor necrosis factor-α and interleukin-1β was as follows: the ischemia/reperfusion stage > ischemic stage > ischemic preconditioning stage (P < 0.05). The levels of above factors in the hydrogen-rich group were significantly lower than those in the control group (P < 0.05). Our findings imply that hydrogen rich water has protective effect on myocardial ischemia/reperfusion injury of the rat hearts in vitro,which may be by reducing the expression of tumor necrosis factor-α and interleukin-1β, and further alleviating the inflammatory response.
