OBJECTIVE:To study the protective effects of Polygonum hydropiper extract on acute gastric mucosal lesion (AGML)in rats. METHODS:48 rats were randomly divided into normal group(normal saline),model group(normal saline), positive group(ranitidine hydrochloride,0.05 g/kg),P. hydropiper extract low-dose,medium-dose and high-dose groups(2.7, 8.1,24.3 g/kg by crude drug),i.g. for consecutive 7 d,once a day. Except for normal group,other groups were given absolute ethyl alcohol to induce AGMI model after 1 h of last administration. 1.5 h after modeling,gastric mucosal lesion index of rats was calculated;the pathological changes of gastric tissue in rats were observed;nuclear factor E2 related factor 2(Nrf2)content and SOD activity in gastric tissue of rats were determined by ELISA. RESULTS:Compared with normal group,the gastric mucosa of model group was damaged obviously,there was blood capillary rupture in submucosa,gastric mucosal lesion index was increased significantly(P<0.01);Nrf2 content and SOD activity were significantly decreased in gastric tissue of rats(P<0.05 or P<0.01). Compared with model group,gastric mucosal lesion of rats was relieved to different extent;in positive group,P. hydropiper extract medium-dose and high-dose groups,gastric mucosal lesion index was decreased significantly(P<0.05),and Nrf2 content and SOD activity were increased significantly(P<0.05 or P<0.01). CONCLUSIONS:P. hydropiper extract has good protective effect on absolute ethyl alcohol-induce AGMI,the mechanism of which may be associated with raising Nrf2 content and enhancing SOD activity in gastric mucosal tissue.

Objective:To report a case with frontotemporal dementia (FTD) characterized by involuntary laughter.Methods:The clinical manifestations and imaging characteristics of a patient diagnosed as FTD was analyzed. Then the results of cerebrospinal fluid, positron emission tomography-computed tomography (PET-CT) and single-photon emission computed tomography examinations were collected. Blood samples were tested for related genes of FTD.Results:The patient is a 66 years old woman with insidious onset and progressing symptoms and she was mainly manifested as laughing out loud involuntarily when looking at others, childishness, stubbornness, loss of interest, irritability and other personal changes. Mild motor and language disorders were also manifested as moving slowly and speaking unclearly. The magnetic resonance imaging showed the atrophy of bilateral frontal, temporal lobe and bilateral hippocampal while the image of PET-CT showed the metabolism was reduced in different degrees. Eventually, behavioural variant of FTD was diagnosed. The result of ANXA11 gene sequencing revealed the mutation of c.107C>G(p.P36R).Conclusions:This is the first case in which a heterozygous mutation of ANXA11 gene, which is related to amyotrophic lateral sclerosis (ALS), is found in simple FTD patient, suggesting that ANXA11 gene may play an important role in the pathogenesis of FTD. This further supports the theory that ALS and FTD are spectrum disorders.

Clinical medicine is a practical, highly skilled natural science. Solid clinical skills are the cornerstone of medical students' growth and development. According to the change of medical education environment, the tension of doctor-patient relationship and the lack of practical ability, we build a set allround , systematic clinical practice teaching system based on practice curriculum teaching , centralized practice teaching, social practice teaching, practice skills assessment and practice skills competition. The research and practice of the system not only promotes teachers' and student's emphasis on the training of clinical practical skills but also improves student's clinical practice skills, strengthen teachers' clinical skills teaching ability, and boost the construction of clinical skills experimental center.
