Objectives To compare the migrating motor complex (MMC) in irritable bowel syndrome (IBS) patients with that in healthy controls. To explore whether discrete clustered contractions (DCC) are connected with abdominal pain in IBS patients. To improve the method of measuring gastroenteric motility (esp. jejunum). Methods By using 16-channel water-perfused catheter and manometry instruments, MMC in 16 cases of IBS with constipation (IBS-C), 18 cases of IBS with diarrhea (IBS-D) and 18 cases of healthy controls were monitored. Results The MMC durations of IBS-C and IBS-D patients were (127.5±25.5) min and (74.5±18.7) min, respectively. Comparision with those in the control group [(87.5±24.2) min]showed significant differences (P<0. 001). The contraction amplitudes of stage Ⅲ in different sites of IBS-C patients decreased significantly as compared with those in the controls [jejunum, (39.8±11.7) mm Hg vs. (61.1±14.1) mm Hg,P<0.001,1 mm Hg=0.133 kPa]. The propagation velocities of stage Ⅲ in different sites of IBS-C patients also decreased significantly as compared with those in the controls [jejunum, (1.8±0.9) cm/min vs. (2.6±0.8) cm/min,P<0.01].The contraction amplitudes of stage Ⅲ in different sites of IBS-D patients increased significantly as compared with those in the controls [jejunum, (69.7±20.5) mm Hg vs. (61.1±14.1) mm Hg, P<0.01]. The propagation velocities of stage Ⅲ in different sites of IBS-D patients also increased significantly as compared with those in the controls [jejunum, (4.1±2.5) cm/min vs. (2.6±0.8) cm/min, P < 0. 01]. DCC incidences of IBS-C and IBS-D were 87.5% and 88. 8%, respectively. Comperision with those in the normal group (83.3%) did not show significant difference (P>0.05). The prevalences of abnormal stage Ⅲ contractions (include disturbances and interferences of stage Ⅲ contractions) in IBS-C and IBS-D patients were 68.8% and 66. 7%, respectively; there were no significant differences between the two groups (P > 0. 05). However abnormal stage Ⅲ contractions did not exist in healthy controls. Conclusions (1) The MMC of IBS-C and IBS-D patients are changed, as compared with that in healthy people; this implies that small intestinal motility dysfunction is one of the pathogenetic factors of IBS. The abnormal stage Ⅲ contractions in jejunum may be a predominant change in IBS gastroenteric motility. (2) No apparent connection is found between DCC and pain in IBS. (3) By using 16-channel water-perfused catheter, we first carried out the method of monitoring jejunum contractions in China. Parameters of MMC in Chinese healthy people were investigated, esp. those of jejunum.

Objective To study the relationship between the spontaneous nocturnal episodes of alkalinization and the autonomic nerve system function and vagal function. Methods 24-hour intragastric pH was measured and auto nomic and vagal function was measured with the time domain analyses of heart rate variability in 20 patients with functional dyspepsia but without diseases of the cardiovascular system. Results 13 of 20 had the nocturnal episodes of alkalinization. The total 24-hour SDNN and rMSSD were normal in 20 subjects with FD. There was no significant dif ference (P ＞0. 05) in the comparison of the total SDNN and rMSSD of the 2 groups with alkalinization and without alkalinization. The 2 groups both had higher PNN50s in the nocturnal time, and there was no significant difference (P ＞0. 05). Conclusion The results suggest that the total autonomic nerve function and vagal function of patients with FD are normal, vagal activities of the 2 groups are both increased in the nocturnal period. The reason for the nocturnal episodes of alkalinization is not a decrease of vagal activity with a subsequent decrease of secretion.

Objective To explore the efficacy,safety and life quality of patients of morphine hydrochloride sustained-release tablets combined with celecoxib in the treatment of advanced lung cancer with moderate to severe cancer-induced pain.Methods A total of 247 patients of advanced lung cancer with moderate to severe cancer-induced pain were randomly divided into combination therapy group (n =127) and morphine monotherapy group (n =120) using simple random sampling digital table method.The differences of dose,efficacy,adverse drug reactions and life quality between the two groups were analyzed.Results In achieving similar analgesic effect,the average maintenance dose of morphine in combination therapy group was (52.51 ±19.92)mg/d,lower than that in monotherapy group [(58.75 ±20.64)mg/d,t =-2.414,P =0.017].The incidence of constipation in combination therapy group was 34.6％,lower than that in monotherapy treatment group (47.5 ％,x2 =4.218,P =0.040).The life quality of the two groups were improved,and the life quality improvement rate in combination therapy group was 59.8％,higher than that in monotherapy treatment group (43.3％,x2 =6.736,P =0.009).Conclusion Morphine hydrochloride sustained-release tablets combined with celecoxib is effective in the treatment of moderate to severe cancer pain,which can reduce the dosage of morphine and reduce adverse reaction,so as to improve the life quality of the patients with advanced lung cancer.

In this paper we studied cryopreservation of Cyclamen persicum Mill. callus to avoid variations produced by sub-culture. The callus in the logarithmic phase after sub-culture were used for experiments. Firstly, the callus were pre-cultured in culture-medium containing 4%, 6% or 8% sucrose for different time periods, transferred to different cryoprotectants to directly cryopreserve or incubated for 2 hours at -20 degrees C, then submersed in liquid nitrogen, lastly thawed rapidly in a waterbath at 37 degrees C, and washed with liquid culture-medium containing the corresponding concentration of sucrose. Cell survival rate was computed after stained by Neutral Red, and SPSS 13.0 software was used for statistical analysis. The results showed that sucrose concentration, pre-culture time, cryoprotectants had various impacts on cell survival rate. We have developed a simple but effective protocol for the cryopreservation of callus of C. persicum. Of the different protocols tested, 4%sucrose, pre-culturing for 3 days, No. 9 cryoprotectant and freezing directly after 30 minutes at 0 degrees C results in the highest cell survival rate.
