Conclusions Integrated nursing intervention with TCM rehabilitation guidance is a method which can effectively help in improving the elbow movement function and the life quality of children with supracondylar humerus fractures of ulnar deviation.

AIM: To observe the effect of Chang'ankang Capsule (Radix Astragali, Rhizoma loptidis, Flos Lonicerae, etc.) on rat's colitis induced by trinitrobenzene sulfonic acid (TNBS) and investigate its mechanism. METHODS: The rat's colitis was induced by TNBS and ethanol, one week later the rats were given the medicine for 14 days. The 21st day the mucosal damage index (CMDI) and histopathology (HP) of the colon were observed. Meanwhile the level of myeloperoxidase (MPO), nitric oxide (NO), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), maiondiadehyde (MDA), catalase (CAT) were detected. RESULTS: CMDI and HP, biochemistry in model rats showed that the models were successful. Chang'ankang groups significantly alleviated CMDI, HP, and improved the high level of MPO, NO and MDA, promoted the content of SOD, GSH-PX, CAT. CONCLUSION: Treatment with Chang'ankang shows beneficial effects on rat's ulcerative colitis by alleviating damage of free radical and NO and leukocyte.

Objective: To compare anti-gastric ulcer action of sea buckthorn pulp oil(SBPO) with sea buckthorn seed oil(SBSO) and to explore its mechanism. Methods : The anti-gastric ulcer actions of SBPO and SBSO were observed and compared on the gastric ulcer induced by water immersion stress, reserpine, pylorus ligation and acetic acid. The effects on gastric secretion in rats were studied with pylorus ligation. The effects on gastric emptying were observed by methyl orange remaining rate in stomach of mouse. The analgesic effect was tested by the hot-plate method and writhing method. Results : SBPO and SBSO markedly inhibited gastric ulcer induced by water immersion stress, reserpine and pylorus ligation and promoted the healing of the gastric ulcer induced by acetic acid. SBPO and SBSO significantly inhibited the secretion of gastric acid and pepsin and promoted the secretion of gastric mucous. SBPO and SBSO delayed gastric emptying in normal mouse. SBPO and SBSO significantly decreased the number of twisting body in mice. Conclusion : Both SBPO and SBSO could have anti-gastric ulcer effect with similar potency. The mechanism of anti-gastric ulcer might be their effect of inhibition of the secrection of gastric juice, promotion of the secrection of gastric mucous, inhibition of activity of gastric smooth muscle and analgetic effect.

Objective: To investigate the absorption and transepithelial transport characteristics of scutellarin and scutellarein in the human colonic adenocarcinoma cell (Caco-2) monolayer model. The influence factors on these two compounds' absorption were investigated, such as buffer solution, duration of culture, and inhibitors of multidrug resistance-associated protein 2 (MRP(2)), breast cancer drug resistance protein (BCRP) and P-glycoprotein (P-gp). Methods: By using Caco-2 monolayer as an intestinal epithelial cell model, the transport process was studied from apical (AP) side to basolateral (BL) side or from BL to AP. The two compounds were determined by high-performance liquid chromatography coupled with diode-array-detector detection. Transport parameters and apparent permeability coeffients (P(app)) were calculated. Results: The P(app) values of scutellarin and scutellarein were different in two buffer solutions, respectively. In phosphate buffered saline, scutellarin had no absorption from AP to BL, while its P(app) value was 0.74×10(-6) to 1.58×10(-6) cm/s from BL to AP. The P(app) values of scutellarein were 4.33×10(-6) to 6.79×10(-6) cm/s and 1.32×10(-6) to 2.56×10(-6) cm/s from AP to BL and from BL to AP, respectively. The P(app) value gradually decreased with time. The absorption of scutellarein was better than that of scutellarin. The scutellarin absorption was improved by verapamil, MK-571 and reserpine. The scutellarein absorption was improved by verapamil whereas its excretion was improved by MK-571. Conclusion: Absorption of scutellarin is difficult in Caco-2 monolayer cells, which contributes to its low bioavailability. Scutellarein absorption is better than scutellarin absorption. Scutellarein transepithelial transport is passive diffusion. The inhibitor of P-gp can improve scutellarin and scutellarein transportation. The inhibitors of MRP(2) and BCRP can promote transportation of scutellarin. The inhibitor of MRP(2) can promote efflux of scutellarein. The multidrug resistance-associated protein may be the second reason for low bioavailability of scutellarin.
