AIM： To determine the precise incidence and clinica features of endoscopic ulcers following gastrectomy. METHODS： A consecutive series of patients who un- derwent endoscopic examination following gastrectomy between 2005 and 2010 was retrospectively analyzed. A total of 78 patients with endoscopic ulcers and 759 without ulcers following gastrectomy were enrolled. We analyzed differences in patient age, sex, size of the le- sions, method of operation, indications for gastric resec- tion, and infection rates of Helicobacterpylor/（H. pylor/~ between the nonulcer and ulcer groups. RESULTS： The incidence of endoscopic ulcers after gastrectomy was 9.3% and that of marginal ulcers was 8.6%. Ulcers were more common in patients with Billroth l] anastomosis and pre-existing conditions forpeptic ulcer disease （PUD）. Infection rates of H. pylori- did not differ significantly between the two groups. The patients who underwent operations to treat PUD had lower initial levels of hemoglobin and higher rates of hospital admission. CONCLUSION： H. pylori was not an important factor in ulcerogenesis following gastrectomy. For patients who underwent surgery for PUD, clinical course of mar- ginal ulcers was more severe.

Crohn's disease(CD) can involve any part of the gastrointestinal tract from the mouth to anus. However, gastroduodenal CD is rare with a frequency reported to range between 0.5% and 4.0%. Most patients with gastroduodenal CD have concomitant lesions in the terminal ileum or colon, but isolated gastroduodenal Crohn's disease is an extremely rare presentation of the disease accounting for less than 0.07% of all patients with CD. The symptoms of gastroduodenal CD include epigastric pain, dyspepsia, early satiety, anorexia, nausea, vomiting, and weight loss. The diagnosis of gastroduodenal CD requires a high level of clinical suspicion and can be made by comprehensive clinical evaluation. Here we report a rare case of isolated duodenal CD not confirmed by identification of granuloma on biopsy, but diagnosed by clinical evaluation.

Several studies have revealed that the preoperative serum testosterone and percent tumor volume （PTV） predict extra-prostatic extension （EPE） and biochemical recurrence （BCR） after radical prostatectomy. This study investigated the prognostic significance of serum testosterone and PTV in relation to EPE and BCR after laparoscopic radical prostatectomy （LRP）. We reviewed 520 patients who underwent LRP between 2004 and 2012. PTV was determined as the sum of all visually estimated tumor foci in every section. BCR was defined as two consecutive increases in the postoperative prostate-specific antigen （PSA）〉0.2 ng ml^-1. The threshold for serum total testosterone was 3.0 ng ml^-1, Multivariate logistic regression was used to define the effect of variables on the risk of EPE and BCR. A low serum testosterone （〈3.0 ng ml^-1） was associated with a high serum PSA, Gleason score, positive core percentage of the prostate biopsy, PTV, and all pathological variables. On multivariate analysis, similar to previous studies, the serum PSA, biopsy positive core percentage, Gleason score, and pathological variables predicted EPE and BCR. In addition, low serum testosterone （〈3.0 ng ml^-1, adjusted OR, 8.52; 95% CI, 5.04-14.4, P = 0.001） predicted EPE and PTV （adjusted OR, 1.02; 95% CI, 1.01-1.05, P = 0.046） predicted BCR. In addition to previous predictors of EPE and BCR, low serum testosterone and PTV are valuable predictors of EPE and BCR after LRP.

Nanovaccines are used as delivery platforms for antigens and adjuvants, which activate antigen-presenting cells (APCs) and enhance anticancer immune responses.1,2 Researchers have recently developed a self-assembled nanocomplex using a polysorbitol-co-PEI (PSPEI) polymer complexed with poly(I:C) (PIC). By binding to different surface proteins, this nanocomplex enhances the intracellular delivery of cargos and induces potent anticancer immune responses against melanoma cells.3 We have previously demonstrated that PD-1/PD-L1 blockade enhanced the efficacy of DC-based cancer immunotherapy.4,5 Moreover, the combination of nanomedicines and PD-L1 blockade has been reported to enhance CD8+ T cell activation and inhibit immunosuppressive cells within the tumor microenvironment.6 In the present study, we investigated the therapeutic efficacy of a combinatorial treatment comprising the immunoadjuvant nanocomplex PSPEI-PIC, a DC vaccine, and PD-L1 blockade in a murine colon cancer model.

Measuring intrinsic hip external rotator strength (ER) without compensatory pelvic motion and activation of the sartorius is important for preventing or rehabilitating lower extremity injuries. However, the optimal method for measuring intrinsic hip ER muscle strength while minimizing compensatory pelvic motions and activation of the sartorius is unclear. The purpose of this study is to compare measurements of hip ER strength, compensatory pelvic motion, and sartorius activation in the sitting, prone, and sidelying positions. Thirty-one healthy subjects (16 males and 15 females) were recruited for this study. Hip ER strength, pelvic kinematics, and sartorius muscle activation were measured during maximal isometric contraction of the hip ER in the sitting, prone, and sidelying positions. Hip ER strength was measured using a load-cell-type strength-measurement sensor. Pelvic kinematics was measured using an electromagnetic motion-tracking sensor. Electromyography was used to measure sartorius muscle activity. Data were analyzed using one-way repeated-measures analysis of variance. The result showed that hip ER strength and sartorius muscle activation were significantly lower in the sidelying compared with the sitting and prone positions (p < 0.01). Pelvic anteroposterior tilting was significantly greater in the sitting compared with the prone and sidelying positions (p < 0.01). Pelvic rotation differed significantly among positions (p < 0.01). Pelvic lateral tilting was significantly greater in the prone compared with the sitting position (p < 0.017). Compensatory pelvic motion and sartorius muscle activation were lower when hip ER strength measurements were made in the sidelying position. Therefore, the sidelying position is effective for measuring selective intrinsic hip ER strength.
