Multifunctional Copper Nanoclusters for the Detection of pH and Berberine Hydrochloride.

The copper nanoclusters (CuNCs) have been garnered significant attention owing to their low cost raw materials, outstanding optical properties, environmental friendliness and good biocompatibility. In this study, copper nanoclusters stabilized by Acid Chromic Blue K (ACBK-CuNCs) were synthesized. The optimal excitation wavelength of the synthesized ACBK-CuNCs is 344 nm and the optimal emission wavelength is 460 nm.

[Effect of shenhuang ointment in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of Qi stagnation blood stasis syndrome: a clinical observation].

Objective: To observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

Methods: A prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases).

Primary desmoplastic small round cell tumor of the duodenum.

The desmoplastic small round cell tumor (DSRCT) is an extremely rare tumor that mainly affects adolescents and mostly involves the abdominal and pelvic peritoneum. A 14-year-old girl presented with intermittent epigastric pain; abdominal computed tomography and upper gastrointestinal barium X-ray revealed an 8 cm × 10 cm space-occupying mass in the duodenal region. The patient underwent pancreaticoduodenectomy and the final pathologic diagnosis was DSRCT.

[Short-term efficacy comparison of laparoscopic-assisted versus open distal gastrectomy].

Objective: To compare the short-term efficacy of laparoscopic-assisted verus open distal gastrectomy for gastric cancer.

Methods: The data of 29 patients with distal gastric cancer from January 2008 to October 2010 were analyzed.

Results: Twenty-eight underwent laparoscopic-assisted distal gastrectomy while 1 was switched to open surgery.

Laparoscopic resection of Bismuth type I and II hilar cholangiocarcinoma: an audit of 14 cases from two institutions.

Objective: To evaluate the feasibility and safety of laparoscopic resection of Bismuth type I and II hilar cholangiocarcinoma.

Background: Laparoscopic resection of hilar cholangiocarcinoma is uncommon.

Method: Fourteen cases of Bismuth type I and II hilar cholangiocarcinoma were selected for laparoscopic resection.

Management of type I choledochal cyst in adult: totally laparoscopic resection and Roux-en-Y hepaticoenterostomy.

Background/objective: Choledochal cysts are congenital dilations of the biliary tree. The accepted mode of treatment is total excision with hepaticojejunostomy. In this retrospective study, we present our technique and results of laparoscopic choledochal cyst excisions.
