Effect of electroacupuncture at "Neiguan" (PC 6) and "Zusanli" (ST 36) on gastrointestinal hormone in the antral tissue of rats with functional dyspepsia.

Objectives: To observe the effects of electroacupuncture (EA) at "Neiguan" (PC 6) and "Zusanli"(ST 36) on the gastric emptying rate, the level of serotonin (5-HT) and the protein expression of motilin (MTL), ghrelin, substance P (SP) and vasoactive intestinal peptide (VIP) in the antral tissue of the rats with functional dyspepsia (FD) and explore the effect mechanism of EA in treatment of FD.

Methods: A total of 21 SPF male SD rat pups were randomly divided into a normal group, a model group and an EA group, with 7 rats in each group. In the model group and the EA group, FD model was prepared by the gavage with 0.

Lobelia chinensis Lour inhibits the progression of hepatocellular carcinoma via the regulation of the PTEN/AKT signaling pathway in vivo and in vitro.

Ethnopharmacological Relevance: Lobelia chinensis Lour. (LCL) is a common herb used for clearing heat and detoxifying, and it has antitumor activity. Quercetin is one of its important components, which may play an important role in the treatment of hepatocellular carcinoma (HCC).

[Comparison of stimulation-induced local changes of expression of local Meckel cell-related proteins and neuropeptides and number of mast cells among acupuncture and moxibustion alone or in combination in chronic atrophic gastritis rats].

Objective: To compare the effects of acupuncture and moxibustion alone or in combination on the number of mast cells and expression levels of cytoketatin 18 (CK18) and CK19 (marker of Meckel cells), and calcitonin gene-related peptide (CGRP), neuropeptide-Y (NPY) and bradykinin (BK) in the local acupoint area of rats with chronic atrophic gastritis (CAG).

Methods: Fifty male SD rats were randomly divided into normal, CAG model, moxibustion, acupuncture and acupuncture+moxi-bustion groups (10 rats in each group). The CAG model was established by gavage of 1-methyl-3-nitro-1-nitrosoguanidine (170 μg/mL,1 mL/100 g, once a week) and 40% ethanol solution (twice a week) for 12 consecutive weeks.

[Impact of ecological protection construction on schistosomiasis transmission of Qionghai Lake wetland in Xichang City].

Objective: To understand the impact of Qionghai Lake wetland ecological protection construction on the prevalence of schistosomiasis, so as to provide the evidence for formulating the strategies for schistosomiasis control and prevention.

Methods: A retrospective survey of the construction of Qionghai Lake wetland was performed, and eleven villages around the wetland were surveyed for schistosomiasis endemic situation. The influence of the wetland project on the schistosomiasis prevalence and Oncomelania hupensis snail status were investigated.

[Water exposure modes and times of different populations in mountainous schistosomiasis endemic areas near Qionghai lake].

Objective: To investigate water exposure modes and times of different populations in mountainous schistosomiasis endemic areas and to inform about the control strategies.

Methods: All 1054 residents from populations around Qionghai Lake were randomly sampled according to occupation for a retrospective questionnaire survey in November 2001. Each individual was interviewed for his/her mode, frequency, and duration of water exposure occurring between April and October 2001.
