The pathogenesis of post- infectious irritable bowel syndrome(PI-IBS)involves abnormal intestinal immune barrier, which possibly includes the pathological aspects: Intestinal and systemic changes in T lymphocyte; the change of inflammatory cytokines; a increase in intestinal mast cells and enterochromaffin cells and so on. Treatment by western medicine based largely on symptomatic treatment. TCM thinks that the fundamental organ of the irritable bowel syndrome is the liver. Emotional factors inducing liver dysfunction lead to the symptoms of irritable bowel syndrome. The pathogenesis of IBS is, the disorder of movement of qi in liver and spleen. Stagnation of liver-QI with deficiency of the spleen or disharmony between liver and spleen is the key pathogenesis of post-infectious irritable bowel syndrome. On this basis, in various stages of the disease, there may be a different pathogenesis. As a special type of IBS, the balance of vital qi and evil factors determine the disease progression of PI-IBS, in the treatment course also should not forget dispelling pathogenic factors while strengthening body resistance, tonifying deficiency and removing dampness。

Esophageal cancer is one of the tumors with high morbidity rates in China, and surgery remains to be the preferred treatment. However, certain complications such as anastomotic fistula, lung infection, respiratory failure, and circulatory failure occur after surgery. Postoperative enteral nutritional support could not only maintain and improve the nutritional status of the body but also re-duce complications and maintain normal immune function. This review focuses on the progress in postoperative enteral nutrition in pa-tients with esophageal cancer.

Objective To investigate clinical value of povidone -iodine disinfection for prevention of postpartum endometritis and abdominal incision infection in cesarean, to provide a reference for clinical treatment. Methods 160 cases of puerpera women were selected, all of them underwent uterine segment cesarean section. According to the digital table,they were divided into control group and observation group,80 cases in each group.In the observation group previous cesarean group remained untreated 30min before cesarean vaginal experiments 0.4%povidone-iodine for disinfection.The maternal postpartum endometritis incidence,abdominal incision infection rate, visual analogue scale,leukocyte index WBC,erythrocyte sedimentation rate index ( ESR) ,C-reactive protein ( CRP) were compared in the two groups.Results There were 32 cases of postoperative endometritis,12 cases (15.00%) occurred in the observation group, 20 cases ( 25.00%) occurred in the control group, the overall incidence of endometritis between the two groups had statistically significant difference (χ2 =5.945,P=0.025);endometritis 5cases (17.86%) premature rupture of membranes occurred in the observation group,the control group had 10 cases (31.25%),the difference was statistically significant (χ2 =6.565,P=0.009).Postpartum WBC,ESR,CRP in the observation group were significantly lower compared to the control group,the differences were statistically significant (t=5.045,P=0.007;t=7.945,P=0.001;t=8.676,P=0.000).In the observation group,postoperative abdominal incision infection rate was 3.75%,compared with the control group,there was no significant difference (χ2 =1.021, P=0.124).The VAS score of the observation group was (3.94 ±0.74),which was significantly lower than (6.25 ± 1.05) of the control group,the difference was statistically significant (t=6.331,P=0.010).Conclusion Previous cesarean vaginal povidone-iodine disinfection is effective in preventing postpartum endometritis,but can't help to low abdominal incision infection or improve wound healing.

The capsule endoscope swallowed from the mouth into the digestive system can capture the images of important gastrointestinal tract regions. It can compensate for the blind spot of traditional endoscopic techniques. It enables inspection of the digestive system without discomfort or need for sedation. However, currently available clinical capsule endoscope has some limitations such as the diagnostic information being not able to correspond to the orientation in the body, since the doctor is unable to control the capsule motion and orientation. To solve the problem, it is significant to track the position and orientation of the capsule in the human body. This study presents an AC excitation wireless tracking method in the capsule endoscope, and the sensor embedded in the capsule can measure the magnetic field generated by excitation coil. And then the position and orientation of the capsule can be obtained by solving a magnetic field inverse problem. Since the magnetic field decays with distance dramatically, the dynamic range of the received signal spans three orders of magnitude, we designed an adjustable alternating magnetic field generating device. The device can adjust the strength of the alternating magnetic field automatically through the feedback signal from the sensor. The prototype experiment showed that the adjustable magnetic field generating device was feasible. It could realize the automatic adjustment of the magnetic field strength successfully, and improve the tracking accuracy.

Objective To investigate a new method for the reconstruction of the urethra using peritoneal free grafts in phalloplasty in a rabbit model. Methods Animal models were established in 24 adult male New Zealand white rabbits, which were randomly divided into the peritoneal graft group (n=12) and peritoneum-skin graft group (n=12). In the former group the peritoneal tube grafts with the mesothelial surface inward were used as the urethral substitutes. And a circumferential 1 cm rim of scrotal skin was inserted at the tip of the tubularized peritoneal graft for urethroplasty in the latter group. Subsequently, a superficial epigastric fasciovascular pedicle flap for phalloplasty was harvested and tubed over the reconstructed urethra. The process of growth was observed grossly. Results The reconstructed penis survived well without urethral stricture, and the peritoneal-lined grafts survived in all rabbits with a smooth, moist quality and without ulceration and fibrosis. Gross examination showed 8 meatal occlusions with fistulas simultaneously in the peritoneal graft group, and 3 fistulas in the peritoneum-skin graft group. Conclusion The authors have successfully designed the rabbit model of the urethroplasty using the tubularized peritoneal free grafts in the penile reconstruction and demonstrated the possibility of the new method for phalloplasty brings a light to clinical study.
