Objective To investigate the effects of hypercholesteremia on the motor function of sphincter of Oddi (SO). Methods Thirty-two rabbits were divided into control group and experimental groups. In the control group, the rabbits were fed with normal diet. In the experimental groups, the rabbits were fed with normal diet + cholesterol for 4, 6 and 10 weeks. Myoelectric activity and pressures of SO were detected. All data were analyzed by t test. Results The serum total cholesterol and low density lipoprotein cholesterol were at a high level in rabbits which were fed with normal diet + cholesterol for 10 weeks (t=9.63, 11.38, P <0.05); basal pressure, pike pressure and amplitude of SO were significantly elevated (t=5.23, 6.34, 3.24, P < 0.05) ; the spike potential of SO changed to myoelectronic activity, with prolonged time period of myoelectronic activity, while the discharge rate was decreased (t=13.68, 10.18, P < 0.05). Conclusion Hypercholesteremia may change the motor function of SO and enhance its peristalsis to speed up the excretion of bile.

Objective To investigate the short-term outcome of laparoscopic adjustable gastric banding (LAGB) for morbid obesity complicated with type 2 diabetes. Methods Eight morbidly obese patients with type 2 diabetes underwent LAGB from October 2006 to August 2007. The weight parameters, fasting (FBG) and 2-hour blood glucose (2hBG), medication for diabetes were assessed 1,3, 6 and 9 months after surgery. Results All of the patients lost weight, with a mean body mass index decreased from (38.7±7.5) kg/m2 before LAGB to (30.5±4.3) kg/m2 9 months after LAGB. The FBG and 2hBG were decreased significantly at month 6 and 9 after LAGB, with normal FBG and 2hBG in 4 patients. At month 9 after LAGB, 3 of 5 patients with insulin treatment before LAGB were changed to oral hypoglycemics, 1 was continuously administered with a reduced dose of insulin, and 4 patients stopped any medication. Conclusion LAGB is an effective procedure in the treatment of morbid obesity complicated with type 2 diabetes with a favorable short-term outcome.

Conclusions Based on short-term follow-up results,LAGB is a safe,effective and feasible technique in the treatment of patients with morbid obesity and obesity-related comorbidities.
10.Exploration on the origin of the red doctor's spirit
Chinese Medical Ethics 2024;37(1):75-79
The red doctor's spirit is an important component of red culture.Inheriting red culture and promoting the spirit of red doctor's are important links in the new journey of building a modern socialist country in all respects.An important prerequisite for promoting the spirit of red doctor's is to clarify the origin of generation and development.Marxism is the theoretical source of the red doctor's spirit,Chinese excellent traditional medical culture is the cultural source of the red doctor's spirit,and revolutionary struggle practice is the practical source of the red doctor's spirit.The three sources converged into a stream,ultimately nurturing the red doctor's spirit.
