[Localization diagnosis of laparoscopic ultrasonograph in laparoscopic surgery of insulinoma].

Objective: To discuss the localization diagnosis value of laparoscopic ultrasonography in laparoscopic surgery of insulinoma.

Methods: Retrospectively reviewed the results of laparoscopic ultrasonography in 32 patients from Jan 2007 to Aug 2008 with insulinoma which confirmed after surgery, and analyzed the detection rate of laparoscopic ultrasonography.

Results: Insulinoma tumors were success located in 31 patients among 32 patients by laparoscopic ultrasonography.

Focal hypoechoic tumors of Fatty liver: characterization of conventional and contrast-enhanced ultrasonography.

Objective: The purpose of this study was to investigate the characteristics of focal hypoechoic tumors of fatty liver using conventional ultrasonography and contrast-enhanced ultrasonography (CEUS).

Methods: Sixty-four hypoechoic tumors of fatty liver in 52 patients were examined by both conventional ultrasonography and CEUS. Contrast pulse sequencing and a sulfur hexafluoride contrast agent were used for CEUS.

Photodynamic therapy for acute central serous chorioretinopathy: the safe effective lowest dose of verteporfin.

Purpose: To find the lowest effective dose of verteporfin in the treatment of acute central serous chorioretinopathy with photodynamic therapy (PDT).

Methods: Patients with acute central serous chorioretinopathy were chosen and treated with PDT with verteporfin. Decreasing doses of verteporfin were applied to the first 7 patients at 70%, 60%, 50%, 40%, 30%, 20%, and 10% of the full dose (6 mg/m).

Laparoscopic surgery for pancreatic insulinomas: a single-institution experience of 29 cases.

Background: Laparoscopic approach has been increasingly used in the treatment of pancreatic benign diseases. This report evaluates our experience with laparoscopic surgery for pancreatic insulinomas.

Methods: Between July 2000 and December 2007, laparoscopic pancreatectomy was attempted in 29 consecutive patients with insulinomas.

Undetermined focal liver lesions on gray-scale ultrasound in patients with fatty liver: characterization with contrast-enhanced ultrasound.

Background And Aim: The purpose of this study was to assess the clinical value and potential impact of contrast-enhanced ultrasound (CEUS) in the characterization of undetermined focal liver lesions (FLLs) in patients with fatty liver.

Methods: Fifty-two patients (34 men, 18 women) with fatty liver with 67 FLLs (size range, 1-8.6 cm; mean, 4.

Protective effect of Weikang decoction and partial ingredients on model rat with gastric mucosa ulcer.

Aim: To investigate the protective mechanisms of Weikang (WK) decoction on gastric mucosae.

Methods: Ninety rats were randomly divided into nine groups of 10 each, namely group, model group, group with large WK dosage, group with medium WK dosage, group with small WK dosage, group with herbs of jianpiyiqi (strengthening the spleen and replenishing qi), group with herbs of yangxuehuoxue (invigorating the circulation of and nourishing the blood), group with herbs of qingrejiedu (clearing away the heat-evils and toxic materials), group with colloidal bismuth pectin (CBP) capsules. According to the method adopted by Yang Xuesong, except normal control group, chronic gastric ulcer was induced with 100% acetic acid.
