Senior citizens have many diseases related to blood stasis, which was often overlooked by clinicians, and thus affected the treatment of the disease. Through analyzing and summarizing of related literature in recent five years of senile constipation treated from blood stasis, we found that the blood stasis is closely linked to senile constipation. Blood stasis in the gut forms constipation, and constipation with the passing of time forms blood stasis in returen. Blood stasis and constipation often influence each other.

This paper introduced the definition of case management, the application of case management model in China and abroad, analyzed the necessity of the implementation of colostomy case management in the field of patients with colostomy, and then discussed the challenges and solving strategies in the delivery of colostomy case management in China in order to provide a theoretical basis for the establishment and promotion of colostomy case management model.

OBJECTIVE To study the protective effect of Orychophragmus violaceus(OV)seed against acute hepatotoxicity induced by the traditional Chinese Medicine Cortex Dictamni in mice. METHODS Twenty-five mice were randomly divided into 5 groups:control group,Cortex Dictamni group(70 g · kg-1)and OV seed groups(36,54 and 72 g · kg-1). OV Seed groups were orally adminis?tered with the aqueous extract of OV seed for 4 consecutive days while the other groups were ig given water. On the 4th day,Cortex Dictamni group and OV seed groups were ig given the aqueous extract of Cortex Dictamni,and normal control group was ig given water. Twenty-four hours later,all the mice had their blood and liver samples taken after anesthesia. The serum chemical parameters were measured, including glutamic oxaloacetic transaminase (GOT),glutamate pyruvate transaminase (GPT) and lactate dehydrogenase(LDH),as well as malondialdehyde(MDA),glutathione(GSH)and oxidized glutathione(GSSG)levels in the liver. GSH/GSSG ratio was calculated. Histopathologic changes in the liver were observed and the area was calculated after HE staining. RESULTS Compared with normal control group,Cortex Dictamni(70 g · kg-1)increased the serum GOT,GPT and LDH levels by 500, 140 and 40 fold(P<0.01). OV seed reduced serum GOT,GPT and LDH levels increased by Cortex Dictamni(P<0.05,P<0.01),by as much as 62%,75% and 99% for GPT,70%,82% and 98% for GOT,and 55%,75%and 96%for LDH,respectively. The level of MDA and the ratio of GSH/GSSG in Cortex Dictamni group were 1.39 ± 0.58 and(3.53 ± 1.27)μmol · g-1,a 10-fold increase and 40%decline compared with normal control group(P<0.01). OV seed of 72 g·kg-1 lowered the level of MDA by 22%(P<0.05),and OV seed(36,54 and 72 g · kg-1)increased the GSH/GSSG ratio by 47%,42%and 54%(P<0.05). Histopathologic results showed that OV seed alleviated the liver damage induced by Cortex Dictamni from(64.1±8.5)%to(37.5±7.1)%and (20.0±0.8)%(P<0.01). CONCLUSION OV seed can effectively protect mice from the acute hepatotoxicity induced by Cortex Dictamni.
