A new metal complex [MnL2]（NO3）***3CN （1） was synthesized by reaction of 4＇-4-（],2,4-triazol-]-yl）- phenyl-2,2＇：6＇,2＂-terpyridine （L） with manganese nitrate. The structure of the complex was determined by X-ray crystallography. The results of UV-vis studies showed that the complex exhibits colorimetric sensing ability for Fe3~, which can be observed by naked eye.

Case presentation A 66-year-old female patient underwent esophagogastroduodenoscopy(EGD)in our center because of occasional dysphagia,and a large submucosal tumor(SMT)was identified 32–36cm from the incisors,occupying nearly half of the luminal circumference(Figure 1A).Mini-probe endoscopic ultrasonography(EUS)revealed a hypoechoic submucosal lesion,measuring 20×15mm and originating from the superficial muscularis propria layer(Figure 1B).It was covered by normal-appearing mucosa.

Acoustic vortex (AV) beam is triggering the significant research interest in information and communication sciences due to its infinite and mutual orthogonal orbital angular momentums (OAMs). Therefore, measuring the topological charges of an AV beams become a task with great significance. In this work, we present a Fraunhofer diffraction (FD) pattern of an AV beam that can be used to quantitatively detect the OAMs of AV beams. We both theoretically and numerically investigate the FD patterns of AV beams passing through a multipoint interferometer (MPI). It is demonstrated that the topological charges of the AV beams can be determined from the interference intensity patterns. The proposed method may pave the way to the practical applications of AV beams.

OBJECTIVE: To assess the value of endoscopy in the etiological diagnosis and treatment of post-cholecystectomy syndrome (PCS).METHODS: 386 patients with PCS were given endoscopic retrograde cholangiopancreatography (ERCP).Having been made the etiology clear, patients with choledocholithiasis were subjected to endoscopicsphincterotomy (EST) or endoscopic papillary balloon dilatation (EPBD) to extract stones, those withpapillary inflammatory stricture to EST or EPBD, those with papillary diverticulum and sphincter of Oddidysfunction (SOD) to EPBD, those with papillary tumor and hepatobiliary tumor to endoscopic metalbiliary endoprosthese (EMBE), and those with biliary stricture in the mid bile duct, purulent cholangitis,choledocholithiasis (stones not extracted one time) and bile leakage to endoscopic nose-biliary drainage(ENBD).RESULTS: ERCP was performed successfully in 371 patients (96.1%). No abnormalities were foundendoscopically in 30 patients. In 243 patients with choledocholithiasis, 235 had stones removed after oneto three times. Thirty-nine patients with papillary inflammatory stricture were successfully treated withEST or EPBD. Nine patients with papillary diverticulum which oppressed the papillary opening and 7patients with SOD were also successfully treated with EPBD. In 16 patients with stricture in the mid bileduct, 11 showed improvement after ENBD. Six patients with papillary tumor and 5 patients withhepatobiliary stricture after EMBE showed significant alleviation of jaundice. Six patients with bileleakage caused by cholecystectomy received ENBD successfully, avoiding re-operation. Six patientsdeveloped gastroduodenal ulcer and 4 residual stones in the cholecystic duct. Complications occurred in 21patients (5.7%).CONCLUSIONS: ERCP may detect the etiology of post-cholecystectomy syndrome at early stage, andtherapeutic measures can be taken accordingly in clinical practice.

AIM: To determine the feasibility and effectiveness of endoscopic resection for the treatment of colorectal granular cell tumors(GCTs). METHODS: This was a retrospective study performed at a single institution. From January 2008 to April 2015, we examined a total of 11 lesions in 11 patients who were treated by an endoscopic procedure for colorectal GCTs in the Endoscopy Center, Zhongshan hospital of Fudan University, Shanghai, China. Either endoscopic mucosal resection or endoscopic submucosal dissection(ESD) was performed by three surgeons with expertise in endoscopic treatment. The pre- and postoperative condition and follow-up of these patients were evaluated by colonoscopy and endoscopic ultrasonography(EUS).RESULTS: Of these 11 lesions, 2 were located in the cecum, 3 were in the ileocecal junction, 5 were in the ascending colon, and 1 was in the rectum. The median maximum diameter of the tumors was 0.81 cm(range 0.4-1.2 cm). The en bloc rate was 100%, and the complete resection rate was 90.9%(10/11). postoperative pathology in one patient showed a tumor at the cauterization margin. however, during ESD, this lesion was removed en bloc, and no tumor tissue was seen in the wound. No perforations or delayed perforations were observed and emergency surgery was not required for complications. All patients were followed up to May 2015, and none had recurrence, metastasis, or complaints of ***: Endoscopic treatment performed by endoscopists with sufficient experience appears to be feasible and effective for colorectal GCTs.
