Effects of Diet on Bile Acid Metabolism and Insulin Resistance in Type 2 Diabetic Rats after Roux-en-Y Gastric Bypass.

Background: Roux-en-Y gastric bypass (RYGB) is effective for the treatment of type 2 diabetes mellitus; however, the mechanism remains unclear.

Methods: The effects of RYGB on postprandial responses to three different diets (low carbohydrate (CH)-rich diet, high CH-rich diet, and fat-rich diet) of different nutritional composition in a Goto-Kakizaki (GK) diabetic rat model were assessed by measuring glucose tolerance, insulin resistance, incretin responses, and bile acid (BA) metabolism.

Results: GK-RYGB group rats lost weight and preferred low CH-rich diet, but there were no significant differences in BW among the different diets.

Greater Curvature Plication with Duodenal-Jejunal Bypass: a Novel Metabolic Surgery for Type 2 Diabetes Mellitus.

Objective: The study investigated the use of great curvature plication with duodenal-jejunal bypass (GCP-DJB) in a type 2 diabetic with obesity rat model.

Methods: Twenty-two Sprague-Dawley rats were given a high fat and sugar diet with subsequent intraperitoneal injection of a small dosage of streptozotocin (30 mg/kg) and randomly assigned to either GCP-DJB (n = 12) or Sham surgery (n = 10). Body weight, peripheral blood glucose, and fasting serum insulin were assayed, and insulin resistance index (IRI) was calculated, before and at 1, 2, 4, and 8 weeks after surgery.

A novel surgical strategy for secondary hyperparathyroidism: Purge parathyroidectomy.

Objective: This study was intended to demonstrate the feasibility and efficacy of purge parathyroidectomy (PPTX) for patients with secondary hyperparathyroidism (SHPT).

Methods: The "seed, environment, and soil" medical hypothesis was first raised, following review of the literatures, to demonstrate the possible causes of persistence or recurrence of SHPT after parathyroidectomy. Subsequently, the novel surgical strategy of PPTX was proposed, which involves comprehensive resection of the fibro-fatty tissues, including visible or invisible parathyroid, within the region surrounded by the thyroid cartilage, bilateral carotid artery sheath, and the brachiocephalic artery.

Routine central neck dissection in differentiated thyroid carcinoma: a systematic review and meta-analysis.

Objective/hypothesis: The role of central neck dissection (CND) remains controversial in differentiated thyroid cancer (DTC).

Study Design: Systematic review and meta-analysis.

Methods: A systematic review and meta-analysis focusing on surgical morbidities and locoregional recurrence after total thyroidectomy (TT) with CND versus TT alone was performed.

[The research of organization behavior model in planning medical equipments purchasing].

The law named The Safety Management Standardization of Medical Apparatus and Instruments in Clinic issued by the government recently, has classified the technical evaluation as one of the aspects of controlling medical risks in demonstration of medical equipments purchasing. This article has researched the organization behavior model, put forward the inevitability of the role in clinical engineering subjection, provided the idea and method of medical equipment purchasing plan, corresponding with the new standardization in now period.

Prevalence, risk factors, and management of seroma formation after breast approach endoscopic thyroidectomy.

Background: Breast approach endoscopic thyroidectomy (BAET) allows surgeons to remove a thyroid tumor from a remote site while providing a scarless cosmetic appearance in the neck. However, seroma formation after subcutaneous dissection could lead to flap detachment, incision dehiscence, and wound infection. Chronic formation of seromas could substantially compromise the esthetic outcome of BAET.
