Objective To develop a reliable scale for evaluating medication compliance among patients with chronic diseases in China.Methods An initial item pool was generated by literature review,based on the definition of compliance generally accepted in China.The items were then subjected to item selections by using item answer distribution and other four methods,which resulted in a primary scale with 16 items.The reliability and validity of this scale was examined.Results Common factors extracted by factor analysis were well explained,there being a close correspondence between the scale construction and the theoretical construction. Convergent validity with the patients' self-ratings on medication compliance ranged from 0.55 to 0.59,and the correlation coefficient with the score of Morisky questionnaire was 0.58.The Cronbach ?,0 and ? coefficients were 0.717,0.751,0.893 respectively,and test-retest reliability was 0.95.Conclusion The newly developed scale appears reliable and may be a useful tool for measuring drug compliance among patients with chronic diseases,but there are still areas where further improvements may be needed.

OBJECTIVETo study the differences in the toxicity of vinegar-processed Kansui Radix on normal and cancerous ascites model rats.

METHODNormal and cancerous ascites model rats were taken as the research objects and orally administered with different doses of vinegar-processed Kansui Radix for 7 d. Pathological sections were prepared to observe the damages in liver, stomach, intestinal tissues in rats and detect the impacts on serum, liver, stomach and intestinal tissues and the oxidative damage index.

RESULTCompared with the blank group, all of normal administration groups and model groups showed significant damages in liver, stomach and intestinal tissues. Compared with the model groups, all of normal administration groups revealed notable alleviation in damages. Compared with the blank group, the model groups showed significant increases in AST, ALT and MDA in serum and liver (P < 0.01) and a significant decrease in GSH in serum and liver, stomach, intestinal tissues (P < 0.01). Compared with the blank group, the results showed significant decreases in ALT, AST in serum and ALT in liver in model low, medium and high dose groups and AST activity in liver tissues in the normal high dose group (P < 0.05, P < 0.01); significant decreases in GSH in serum and stomach tissues in normal low, medium and high dose groups and GSH content in liver and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01); notable rises in MDA in liver tissues in normal low, medium and high dose groups and MDA content in serum and stomach and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01). Compared with model groups, data revealed significant decreases in ALT, AST in serum in model low, medium and high dose groups, AST in liver tissues of model medium and high dose groups and ALT activity in liver in the model high dose group (P < 0.05, P < 0.01); significant increases in GSH content in serum and stomach tissues of model low, medium and high dose groups, GSH in liver tissues in model medium and high dose groups and GSH in intestinal tissues in the high dose groups (P < 0.05, P < 0.01); and notable declines in MDA content in serum in model low, medium and high dose groups, MDA in liver tissues of model medium and high dose groups and MDA in stomach and intestinal tissues the high dose group (P < 0.05, P < 0.01).

Objective:This study was designed to explore the effects and mechanisms of raltitrexed on the growth of the human gastric cancer cell line (MGC-803) transplanted in nude mice. Methods: Models of MGC-803 xenograft transplanted in nude mice were established. Body weight, mental state, food, and stool of the nude mice were closely monitored, and the inhibitory action in the tu-mors was evaluated after drug intervention. Distribution and apoptosis of the tumor cells were examined through flow cytometric assay. P53 mRNA and protein expression levels were determined through reverse transcription-polymerase chain reaction and Western blot analysis. Changes among the three groups were compared. Results:Body weights and tumor volumes of the nude mice were lower in the raltitrexed and 5-fluorouracil (5-Fu) groups than those in the control group. Tumor inhibition ratios were 49.02%and 45.75%in the raltitrexed and 5-Fu groups, respectively. In the G0/G1 stage, the number of cells decreased in the raltitrexed and 5-Fu groups. Signifi-cant differences were found between the experimental and control groups (P<0.01). In the S stage, the number of cells increased in the raltitrexed and 5-Fu groups, with significant differences from the control group (P<0.01). P53 mRNA and protein expression levels in the raltitrexed and 5-Fu groups were significantly higher than those in the control group (P<0.01), but no significant differences were found between the raltitrexed and 5-Fu groups (P>0.05). Conclusion:Raltitrexed can inhibit the growth of MGC-803 xenograft trans-planted in nude mice and shows inhibitory effect similar to that of 5-Fu. Raltitrexed can induce the S-phase block of the cell cycle and cell apoptosis in the MGC-803 xenografts in the nude mice. This drug may exhibit an antitumor effect by upregulating the p53 mRNA and protein expression levels.

Objective To evaluate the feasibility of bladder extracellular matrix (BACM) seeding with autologous cultured vaginal smooth muscle cells (VSMC) repaired rabbit vaginal defect.Methods This study included 24 female rabbits.BACM and vaginal acellular matrix (VACM) were obtained from 8 rabbits by decellularization process.The other 16 rabbits were randomly divided into experimental and control groups.Vaginal tissue biopsies ( ～ 1 cm2) were harvested from female New Zealand rabbits.VSMC were cultured and stained with a-smooth muscle actin antibodies. Cultured VSMC cells were seeded on BACM ( experimental group) or VACM ( control group) at a cell density of 1 × 107 cells/cm2.The cell-seeded matrixes were cultured for 5days.In experimental group of 8 rabbits,a 2 cm segment of vagina was resected and replaced with BACM seeding with VSMC.Then the regenerative segment was studied with histological technique by hematoxylin-eosin staining after 3,6 and 12 weeks postoperative aud vaginography was performed at 12 weeks postoperative.The 8 rabbits in control group underwent the exact same procedure as above but the vaginal defect was repaired with VACM seeding with VSMC,Results The prepared BACM and VACM were transparent,HE staining and scanning electron microscopy showed the two acellular matrix was both consisted of abundant network of fibers with the regular arrangement,without cellular debris.Primary culture of VSMC was successfully established and passaged,and was uniformly spindle-shaped in the confluent state and showed a characteristic hill and valley'formation.Immunohistochemical staining showed VSMC in culture stained positively with a-smooth muscle actin antibodies.VSMC began to adhere to the BACM 5 hour after implanting and the number of the adhered cells increased with time.Cells gradually expanded and showed the typical morphology of smooth muscle cells.Three weeks after implantation in vivo,the luminal surface of matrix was completely covered by vaginal epithelial tissue,a layer of smooth muscle cells was formed in the outer surface of the matrix.Multilayered vaginal epithelial and improved development of organized muscle bundles was observed after 6 weeks.The regenerative tissue was equivalent to the normal vaginal tissue at 12 weeks postoperatively.Vaginography demonstrated the maintenance of full patency and a wide vaginal caliber without fibrosis and graft rejection.There was no significant difference in all evaluated items between experimental and control groups.Conclusions BACM has the same regenerative process as VACM in the replacement of vaginal defect.Moreover,BACM has wider source and appears to be an suitable material for vaginal replacement.

Objective To investigate the alteration of serotonin-producing gastric enterochromaffin (EC)cell in patients with functional dyspepsia(FD).Methods Fifteen healthy volunteers and 33 patients with FD were enrolled.Proximal gastric mucosal EC cells were countered after immunohisto- chemistry staining.The ultrastructure of EC cell was observed by electromicroscope.Results The EC cells in proximal gastric mucosa in patients with FD were significant higher than that in controls(12.5?2.1 vs 8.3?1.4,t=2.353,P＜0.05),and the staining intensity of EC cell in patients with FD was also stronger than that in controls(3.72?0.42 vs 2.61?0.57,t=2.078,P＜0.05).The more sever the gastric mucosal inflammation was,the more number of EC cells and the stronger staining intensity were.Under the electromicroscopy,more Golgi apparatus,mitochondria and endoplasmic reticulum were found in EC cells.Special secreting particles were also found in cytoplasm.Conclusions EC cells may be involved in the pathogenesis of FD.The number of EC cell is related with the severity of gastric mucosal inflammation.

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.
