Objective To investigate the variety of antro duodenal motility in patients with diarrhea or constipation predominant irritable bowel syndrome (IBS) and to elucidate the pathophysiology of IBS. Methods After 6 hours fasting, 17 patients with IBS (diagnosed by Rome Ⅱ criteria), 8 with diarrhea predominant diarrhea(D IBS) and 9 with constipation predominant IBS(C IBS), were investigated by gastrointestinal manometry (STD Co., Sweden) for recording at least 2 intergrated interdigestive migrating motor complex (MMC) cycles and observing 2 hours of postprandial antro duodenal motility. Results The MMC periods was shorter, phase Ⅲ duration was longer and amplitude was higher in D IBS group than in controls, whereas the MMC periods was longer and the phase Ⅲ duration was shorter in C IBS group than in controls. The duration of discrete clustered contraction(DCC) in phase Ⅱ was longer in IBS groups than in health controls, but there was no significant difference between the C IBS group and the D IBS group. The motility index in late phase Ⅱ and phase Ⅲ was higher in IBS D group, but for the IBS C group the motility index had no statistical difference from that for controls. The postprandial motility pattern of duodenum had no remarkable difference between IBS patients and controls. Conclusions The gastrointestinal motility disorders are apparent in the IBS patients. There is close relation between gastrointestinal motility disorders and the symptoms of the IBS patients. DCCs waves may almost be independent of constipation or diarrhea of IBS.

Objective To analyze the effect of Shuxuetong injection on microcirculation in patients with septic shock and its therapeutic effect. Methods A prospective study was conducted. Eighty patients with septic shock treated in Department of Critical Care Medicine of Hebei Provincial Traditional Chinese Medical Hospital were randomly divided into a Shuxuetong group and a conventional therapy group according to random number table, 40 cases in each group. The conventional treatment in the two groups was energetically carried out in accord to the sepsis shock guidelines, such as positive fluid resuscitation, anti-infection, etc. In the Shuxuetong group, additionally Shuxuetong injection 6 mL in 5% glucose injection 250 mL intravenous drip was given once a day for 7 days. The levels of urine output, lactic acid (Lac), blood urea nitrogen (BUN), creatinine (Cr), aspartate aminotransferase (AST), alanine aminotransferase (ALT), left ventricular ejection fraction (LVEF), and cardiac index (CI) in the two groups were observed before and after treatment; the total dosages of dopamine, dobutamine, noradrenaline, etc. vascoactive agent used for the patients and 28-day mortality in the two groups were also recorded. Results The comparisons of levels of urine output, Lac, BUN, Cr, AST, ALT, LVEF, and CI before treatment between the two groups were of no statistical significant differences (all P>0.05). After treatment in the two groups, the urine output, LVEF, and CI were increased compared with those before treatment, whereas the Lac, BUN, Cr, AST, and ALT were significantly decreased, and the changes were more obvious in Shuxuetong group [urine output (mL/h):112.1±39.8 vs. 73.3±28.5, LVEF:0.49±0.15 vs. 0.44±0.14, CI (mL·s-1·m-2):66.2±5.7 vs. 54.2±6.2, Lac (mmol/L):3.83±1.65 vs. 4.72±2.25, BUN (mmol/L):7.1±2.7 vs. 9.3±3.5, Cr (μmol/L): 73.9±16.2 vs. 95.7±15.8, AST (U/L): 39.8±9.5 vs. 45.8±12.7, ALT (U/L):34.3±9.7 vs. 41.7±11.3, all P<0.05]. The total dosages of all kinds of vascoactive agent of Shuxuetong group were remarkably less than those in the conventional therapy group [dopamine (mg): 993.1±261.7 vs. 1 340.9±356.4, dobutamine (mg):776.2±281.0 vs. 1 049.2±364.3, noradrenaline (mg):56.4±34.6 vs. 107.6±51.3, all P<0.05]. The 28-day mortality of Shuxuetong group was obviously lower than that of conventional therapy group [40.0%(16/40) vs. 60.0%(24/40), P<0.05]. Conclusion Shuxuetong injection can improve the microcirculation perfusion in patients with septic shock and reduce their mortality.

OBJECTIVETo evaluate remineralization efficacy of an arginine containing dentifrice on initial enamel carious lesions in vitro.

METHODSHuman enamel blocks with early lesions were prepared and randomly divided into three treatment groups: negative control group (distilled and deionized water), positive control group (fluoride containing dentifrice and 0.14% sodium monofluorophosphate), and test dentifrice group (8.0% arginine and 0.14% sodium monofluorophosphate). The lesions were subjected to a pH-cycling regime for 10 days. Surface enamel microhardness of the enamel blocks from each group was measured before and after pH cycling, and the surface microhardness recovery was calculated. Then, specimens were analyzed for enamel fluoride uptake (EFU) through acid etching method, after which they were treated in demineralization solution for a 2 h period of acid challenge. The other specimens were sectioned and examined through polarized light microscopy.

RESULTSIn the test dentifrice group, microhardness recovery and EFU were significantly higher than those in the negative control and positive groups. The test dentifrice group was significantly resistant to the acid challenge compared with the other groups. Conspicuous remineralization of enamel subsurface lesions was observed under polarized light microscopy among samples treated with test dentifrice, whereas the control groups showed no significant changes on enamel subsurface lesions.

CONCLUSIONThis study presents the potential superiority of Pro-Argin dentifrice over conventional fluoride dentifrice in promoting the remineralization of initial enamel lesions.
