Controlled Clinical Trial
Electroacupuncture accelerates solid gastric emptying and improves dyspeptic symptoms in patients with functional dyspepsia.
The aims of this study were to investigate the effects of electroacupuncture (EA) at ST36 and PC6 points on solid gastric emptying and dyspeptic symptoms in patients with functional dyspepsia. Nineteen patients with functional dyspepsia (FD) were involved in the study, consisting of two parts: (1) acute effects of EA on solid gastric emptying in FD patients with delayed gastric emptying and (2) short-term (2-week) effects of EA on symptoms in FD patients with normal gastric emptying. Results were as follows. (1) Ten of the19 patients showed delayed gastric emptying of solids, and acute EA significantly improved delayed gastric emptying; the halftime for gastric emptying was reduced from 150.3+/-48.4 to 118.9+/-29.6 min (P=0.007). (2) In the nine patients with normal gastric emptying, 2-week EA significantly decreased the symptom score, from 8.2+/-3.3 at baseline to 1.6+/-1.1 (P < 0.001) at the end of treatment. We conclude that EA at the ST36 and PC6 points accelerates solid gastric emptying in FD patients with delayed gastric emptying and relieves dyspeptic symptoms in FD patients with normal gastric emptying.

Preclinical studies have shown that a very low dose of naltreoxone hydrochloride (NTX), an opiate antagonist, can block excitatory opioid receptors without affecting inhibitory opioid receptors, resulting in analgesic potency without side effects. The present study assessed the efficacy and safety of PTI-901 (low-dose NTX) treatment in Irritable bowel syndrome (IBS) patients. Forty-two IBS patients participated in an open-label study. ⋯ There were no significant adverse reactions. PTI-901 improves pain and overall feeling, and is well tolerated by IBS patients. A large, randomized, double-blind, placebo-controlled study is justified.

The hepatic venous pressure gradient (HVPG) clearly reflects portal pressure in cirrhotic portal hypertension. Its relation with variceal bleeding has been well studied. We undertook to study the relation of HVPG to variceal size, Child's status, and etiology of cirrhosis. ⋯ There is a good correlation between HVPG and large varices, bleeder status, and ascites. A higher HVPG reflects more severe liver disease. The etiology of liver disease did not influence the portal pressure.
