Objective:To discuss the influence and curative effect of bifidobacterium tetravaccine tablets on serum substance P ( SP) and neuropeptide Y ( NPY) levels in the patients with irritable bowel syndrome ( IBS) . Methods: Totally 84 cases of patients with IBS were selected and divided into the observation group and the control group at random. The patients in the two groups were both given the medical treatment, such as diet adjustment, malntenance of water and electrolyte acid-base balance, administration of gastro-intestinal antispasmodic and antidiarrheal agents. The patients in the observation group were additionally given 0. 15g bifidobacterium tetravaccine tablets per time, three times a day for 8 weeks. The changes of serum SP and NPY levels in the two groups before and after the treatment were observed, and the clinical curative effect and adverse drug reaction ( ADR) were compared. Results:After the 8-week medical treatment, the serum SP level in the two groups was obviously declined than that before the treatment, while the NPY lev-el was obviously ralsed than that before the treatment (P<0. 05 or P<0. 01), and the declining or increase in the observation group was much higher than that in the control group (P <0.05). Meanwhile, the total clinical efficiency in the observation group was 95. 24%, which was much higher than that in the control group (78. 57%, P<0. 05). After comparing the occurrence of ADR be-tween the two groups, no statistical differences were appeared (P>0. 05). Conclusion:Bifidobacterium tetravaccine tablets show reli-able curative effect on IBS with high security, and the curative effect has close relationship with inhibiting the release of SP, enhancing the release of NPY, adjusting the excitement of braln gut axis and inhibiting the imbalance of braln gut petide in the patients with IBS.

OBJECTIVETo study the effect of GABA transporter (GAT-1) on the analgesic action of oxysophoridine (OSR) in the central nervous system of mice.

METHODHot plate test was used to observe and analyze the effect of gamma aminobutyric acid and the inhibitor of GAT-1 (NO-711) on the analgesic action of oxysophoridine. Real time RT-PCR was used to investigate the influence of OSR on the expression of GAT-1 mRNA induced by formalin in spinal cord and brain of mice.

RESULTBoth GABA (2.0 mg x kg(-1), icv) and NO-711(0.125 mg x kg(-1), icv) enhanced the analgesic action of OSR (32.0 mg x kg(-1), iv) in the hot plate test, and the latencies was markedly increased (P < 0.05, P < 0.01). OSR (500.0 mg x kg(-1), iv) significantly inhibited the expression of GAT-1 mRNA induced by formalin (P < 0.05).

CONCLUSIONGAT-1 was involved in the analgesia effect of OSR and the down-regulation of GAT-1 mRNA enhanced the analgesic effect.

Acute pancreatitis is a common acute abdominal disease of the digestive system characterized by multiple etiologies and rapid progression, and early diagnosis and treatment are closely associated with the prognosis of patients. Among various radiological examinations, ultrasound can perform real-time dynamic comprehensive scans of the pancreas and the biliary system and thus plays an important role in etiological diagnosis, grading, and treatment. This article reviews the current status and prospects of ultrasound in acute pancreatitis, in order to provide a reference for the diagnosis and treatment of acute pancreatitis.
