Effect of Shuwei Decoction () on rats with functional dyspepsia

OBJECTIVE

To investigate the effects of Shuwei Decoction (, SWD) on gastric emptying, serum stem cell factor (SCF), the content of serum nitric oxide (NO), and structure change of interstitial cells of Cajal (ICC) in functional dyspepsia (FD) rats.

METHODS

Sixty Sprague Dawley rats were randomly divided into 6 groups: blank group (group A), model group (group B), mosapride group (group C), Muxiang Shunqi Pill (, MSP) group (group D), SWD low-dose group (group E), and SWD high-dose group (group F), 10 rats in each group. FD rat model was established by clasping rats' tails for 7 days, except the group A. After 3 days, group A and group B were given distilled water, and the medicated rats were given corresponding medicine for 14 days. The gastric emptying, structure change of ICC in gastric antrum by transmission electron microscope, the content of serum NO by nitrate reductant and SCF by enzyme linked immunosorbent assay were observed.

RESULTS

Compared with group A, the rats in group B delayed gastric emptying, serum SCF decreased, serum NO increased (P <0.05). Compared with group B, the rats in groups D, E and F were improved on gastric emptying, obviously increased on serum SCF, decreased on serum NO (P <0.05), and structure change of ICC in gastric antrum improved. Compared with group B, structure change of ICC of group E after treatment was improved and was closed to group A.

CONCLUSION

SWD recovered gastrointestinal motility of FD, possibly by regulating the levels of serum NO and SCF, and improving the structure of ICC in gastric antrum.

Evidence-based nursing in infants with congenital megacolon

AIM: To investigate the clinical significance of evidence-based nursing in infantile patients with congenital megacolon.

METHODS: Fifty infantile patients with congenital megacolon hospitalized at our hospital from January 2008 to December 2013 were retrospectively analyzed. According to the measure of nursing intervention after admission, the patients were divided into either a conventional nursing group or an evidence-based nursing group. The nursing effects were compared between the two groups.

RESULTS: Complications occurred only in 3 cases in the evidence-based nursing group, and none of them had multiple simultaneous complications. In contrast, complications occurred in 61 children in the conventional nursing group, of whom 6 developed only one complication, 17 had two concurrent complications, and 7 had three complications (χ² = 41.667, P = 0.000). The incidences of water and electrolyte imbalance, malnutrition, and hemodynamic instability were significantly lower in the evidence-based nursing group than in the conventional nursing group (P < 0.05). The length of hospital stay and the incidence of anastomotic obstruction were also significantly lower in the evidence-based nursing group than in the conventional nursing group (P < 0.05).

CONCLUSION: Evidence-based nursing may be helpful to reduce the incidence of complications and shorten the length of hospital stays in patients with congenital megacolon.
