Comparison of high-dose dual therapy with bismuth-containing quadruple therapy in Helicobacter pylori-infected treatment-naive patients: An open-label, multicenter, randomized controlled trial.

Objective: Bismuth-containing quadruple therapy for Helicobacter pylori (H. pylori) eradication has a relatively high rate of side effects and high cost, thus the option of a high-dose dual therapy with a high eradication rate and fewer adverse events is a consideration. However, studies of dual therapy are still scarce and are mostly single-center studies with limited generalizability.

Pirfenidone prevents radiation-induced intestinal fibrosis in rats by inhibiting fibroblast proliferation and differentiation and suppressing the TGF-β1/Smad/CTGF signaling pathway.

Radiation-induced intestinal fibrosis (RIF) is a chronic toxicity following radiation, and can be very difficult to treat. Pirfenidone is a promising anti-fibrotic agent that inhibits fibrosis progression in various clinical and experimental studies. This study was aimed to explore whether pirfenidone could protect against RIF, and to evaluate the underlying mechanism.

Monitoring neoadjuvant therapy responses in rectal cancer using multimodal nonlinear optical microscopy.

Most patients with rectal cancer have a better prognosis after receiving neoadjuvant therapy because of its remarkable curative effect. However, no device delivers real-time histopathologic information on treatment response to help clinicians tailor individual therapeutic strategies. We assessed the potential of multimodal nonlinear optical microscopy to monitor therapeutic responses, including tumoral and stromal responses.

Foxp3 expression in CD4CD25Foxp3 regulatory T cells promotes development of colorectal cancer by inhibiting tumor immunity.

The mechanism underlying CD4CD25Foxp3 regulatory T cells (Tregs) promoting the development of colorectal cancer (CRC) was elucidated in the present study. Forty-eight cases of colorectal carcinomas, 22 cases of colon polyps and 21 cases of normal colorectal tissues were collected. The correlation among Foxp3, IL-10 and Stat3, and the clinical relevance of these three indexes were analyzed.

Multiphoton microscopy for tumor regression grading after neoadjuvant treatment for colorectal carcinoma.

Aim: To evaluate the feasibility of using multiphoton microscopy (MPM) to assess a tumor regression grading (TRG) system.

Methods: Fresh specimens from seven patients with colorectal carcinoma undergoing neoadjuvant radiochemotherapy at the Fujian Medical University Union Hospital were obtained immediately after proctectomy. Specimens were serially sectioned (10 µm thickness) and used for MPM or stained with hematoxylin and eosin for comparison.

Laparoscopic transabdominal approach partial intersphincteric resection for low rectal cancer: surgical feasibility and intermediate-term outcome.

Background: Traditionally, conventional intersphincteric resection requires a combined abdominal and perineal approach and a handsewn coloanal anastomosis procedure, which is difficult to accomplish via the perineal approach. A completely abdominal approach partial intersphincteric resection (APISR) with laparoscopy can simplify the anastomosis procedure. This study evaluated the intermediate-term oncological and functional results of laparoscopic versus open APISR for low rectal cancer.

Evodiamine activates AMPK and promotes adiponectin multimerization in 3T3-L1 adipocytes.

Adiponectin, an adipokine with insulin-sensitizing effect, is secreted from adipocytes into circulation as high, medium, and low molecular weight (HMW, MMW, and LMW) forms. The HMW adiponectin is more metabolically active and the ratio of HMW adiponectin to total adiponectin directly correlates with insulin sensitivity. Evodiamine is an indole alkaloid found in the traditional Chinese medicinal plant Evodia rutaecarpa.

[Meta analysis of postoperative complications between laparoscopic resection and traditional open resection of mid-low rectal carcinoma].

Objective: To conduct a meta-analysis of postoperative complications between laparoscopic resection (Group LR) and traditional open resection (Group OR) of mid-low rectal carcinoma.

Methods: Meta analysis was performed by two reviewers, who independently selected and extracted data retrieved from literatures and papers published in China Knowledge Resource Integrated Database (CNKI), Wangfang Data, Foreign Medical Journal Service (FMJS), PubMed, EMBASE and The Cochrane before August 2012 on comparison between two groups. The statistical analysis for research of complex standard was conducted through Revman 5.

[Efficacy and safety of sunitinib on patients with imatinib-resistant gastrointestinal stromal tumor].

Objective: To investigate the efficacy and safety of sunitinib on the management of gastrointestinal stromal tumors (GIST) patients with imatinib resistance.

Methods: Clinical data of 48 patients with imatinib-resistant GIST received sunitinib therapy from May 2008 to April 2012 in the Union Hospital of Fujian Medical University were analyzed retrospectively. Eighteen patients received 50 mg/d of sunitinib in a protocol of 4/2 (4 weeks on and 2 weeks off) [50 mg/d (4/2)], and 30 patients received a protocol of 37.

Interleukin-18 and -12 synergistically enhance cytotoxic functions of tumor-infiltrating lymphocytes.

Background: The role of tumor-infiltrating lymphocytes (TILs) in the immunopathogenesis of individual cancer is not clear and is a challenge for anti-tumor immunotherapy. This study aimed to investigate the effects of interleukin (IL)-18 and -12 on cytotoxic functions of TILs.

Methods: TILs from postoperative gastric cancer patients were costimulated with IL-18 and IL-12.

Laparoscopic extralevator abdominoperineal resection for rectal carcinoma with transabdominal levator transection.

Background: The extralevator abdominoperineal resection (ELAPR) is a new surgical technique for patients with low advanced rectal cancer. This technique requires an extra excision of the levator muscles to avoid the surgical waist caused by the conventional abdominoperineal resection, with the patient's position changed to a prone jackknife position and using a myocutaneous flap to repair the pelvic defect. To simplify this operation, we applied a laparoscopic technique to perform controlled transabdominal transection of the levator muscles under direct visualization without a position change and pelvic floor reconstruction using human acellular dermal matrix (HADM).

[Laparoscopic cylindrical abdominoperineal resection with transabdominal approach for lower rectal cancer].

Objective: To evaluate the safety and feasibility of laparoscopic cylindrical abdominoperineal resection.

Methods: Six patients with rectal adenocarcinoma within 3 cm above the anal verge underwent laparoscopic cylindrical abdominoperineal resection. Transabdominal levator transaction was performed laparoscopically, with no position change during the perineal operation.

[Short-term efficacy of laparoscopic-assisted right hemicolectomy with D3 lymph node dissection in colon cancer].

Objective: To explore the feasibility and short-term efficacy of laparoscopic-assisted D3 lymph node dissection for right colon cancer with a medial-to-lateral approach.

Methods: Clinical data of 61 patients with right colon cancer undergoing D3 lymph node dissection from March 2006 to June 2010 were analyzed retrospectively. Among them,29 underwent laparoscopic-assisted right hemicolectomy (LARH group) and 32 underwent open right hemicolectomy (ORH group).

(R)-1,1'-Binaphthalene-2,2'-diyl dicinnamate.

In the title compound, C(38)H(26)O(4), two cinnamo-yloxy groups are linked in a trans fashion to the two O atoms of optically active (R)-1,10-bi-2-naphthol. The dihedral angle between the mean planes of the two naphthyl groups is 71.8 (1)°.

Syndecan-1 and E-cadherin expression in differentiated type of early gastric cancer.

Aim: To elucidate the role and alterations of syndecan-1 and E-cadherin expression in different cellular phenotypes of differentiated-type gastric cancers (DGCs).

Methods: A total of 120 DGCs at an early stage, and their adjacent mucosa, were studied both by immunohistochemistry. Syndecan-1 and E-cadherin were assessed by immunohistochemical staining with anti-syndecan-1 and anti-E-cadherin antibodies, respectively.
