Objective To assess the efficacy and safety of premedicaton with pronase before upper gastrointestinal endoscopy (UGI).Methods A total of 440 outpatients from 5 centers were randomly assigned to receive endoscopy with one of three premedications as follows:dimethylpolysiloxane (DMPS) and pronase (group A,n =170) ; DMPS and sodium bicarbonate (group B,n =170) ; DMPS,pronase and sodium bicarbonate (group C,n =100).Six endoscopists,who were unaware of the premedication types,calculated the visibility scores (range,1 to 4) of the antrum,gastric body,and fundus.The sum of the scores from the three locations was defined as the total visibility score.Results With regards to routine white light endoscopy,the total visibility score of group C was significantly higher than that of group A (P =0.0001),and the score of group A was significantly higher than that of group B (P =0.0019).Concerning chromoendoscopy,the total visibility score of group C was significantly higher than that of group A (P =0.0054),and the score of group A was also significantly higher than that of group B (P ＜ 0.0001).Conclusion Combined application of pronase,dimethylpolysiloxane,and sodium bicarbonate before UGI endoscopy significantly improves endoscopic visualization.

Objective To investigate the expression of CD40 and intercellular adhesion molecule-1 (ICAM-1) treated with lipopolysaccharide (LPS) in rat peritoneal mesothelial cells(RPMC) and the role of NF-κB signal transduction pathway. Methods RPMCs were harvested from Sprague-Dawley rat peritoneal cavity and maintained under defined in vitro conditions. The cells were exposed respectively to different concentrations of LPS for 12 h or treated with LPS (5 μg/ml) for different time points. To observe the effect of LPS on the expression of CD40 and ICAM-1, the RPMCs were treated with LPS (5 μg/ml) for different time points. To observe the effect of LPS on the expression of NF-κB and p-NF-κB protein, the RPMCs were treated by LPS or pretreated with BAY11-7085 (5 μmol/L or 1 μmol/L ) for 3 h, then treated with LPS for another 3 h, respectively. Expression of CD40 and ICAM-1 mRNA was examined by RT-PCR. Expression of NF-κB and p-NF-κB protein was detected by Western blot. Results Compared with medium control group, stimulation of RPMCs with 1 μg/ml and 5 μg/ml of LPS resulted in a significant increase in the expression of CD40 and ICAM-1 mRNA(P<0.05). 10 μg/ml of LPS had strongest effect on CD40 and ICAM-1 expression compared with that of 1 μg/ml and 5 μg/ml of LPS. Treatment with 5 μg/ml of LPS resulted in time-dependent increase in the gene level of CD40 and ICAM-1, with the peak at 3 h. However, after that time point, the gene level of them was gradually attenuated. Following treatment with LPS (5 μg/ml), the level of p-NF-κB began to increase at 15 min, gradually reached the peak at 1 h, and then decreased. But the level of p-NF-κB at 2 h was still significantly higher than that of medium control. 5 μmol/L of BAY11-7085 decreased significantly the up-regulation of CD40 and ICAM-1 induced by LPS. Conclusion LPS enhanced the expression of CD40 and ICAM-1 on RPMCs in a concentration-dependent and a time-dependent manner. LPS induced expression of CD40 and ICAM-1 depend on the NF-κB signal transduction pathway.

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.

The completion of the Human Genome Project lays a foundation for systematically studying the human genome from evolutionary history to precision medicine against diseases. With the explosive growth of biological data, there is an increasing number of biological databases that have been developed in aid of human-related research. Here we present a collection of human-related biological databases and provide a mini-review by classifying them into different categories according to their data types. As human-related databases continue to grow not only in count but also in volume, challenges are ahead in big data storage, processing, exchange and curation.

OBJECTIVE: To explore the injury mechanism of the human knee in a traffic accident by establishing a 3D finite element (FE) model. METHODS: The FE model, composed of femur, tibia, fibula, patella, meniscus, knee ligaments and surrounding soft tissues, was reconstructed by CT scanning data from a male volunteer. Validation was performed by the lateral impact simulation, and the stress and strain results were obtained to be compared with those previously reported for injury prediction. RESULTS: The results derived from the FE model were found to be similar with those previously reported, most of the ligaments and meniscus wounded at 40 m/s collision, which was readily observed. CONCLUSION The simulation results generated by FE model can be effectively used for the injury mechanism analysis of initial contact.
