Objective To observe the effect of acupuncture combined with traditional Chinese medicine on serum leptin contents and the expression of leptin receptor in the hypothalamus in simple obesity rats so as to explore the underlying mechanism. Methods A total of 120 male Wistar rats were randomly divided into normal control group and high grease group, which was established by fed with high fat forage for 16 weeks. 60 successful rat models were divided into shilianyin+electro-acupuncture group, fatness model group, and control group with random digits table. Electro-acupuncture was applied to Zusanli and Zhongwan, and Shilian-yin 22.4 g/kg was administered, once daily, for 14 days in the shilianyin + electro-acupuncture group; Fatness model group was lavaged with isotonic Na chloride 2 ml/kg; while the control group was lavaged with sibutramine 1.6 mg/kg. The body weight, body length and Lee's index were measured once every 10 days. Serum leptin contents were measured by radioimmunoassay, and leptin receptor expression was detected with immunohistochemistry. Results In comparison with fatness model group (13.401 ± 6.138) ng/ml, the serum leptin content of shilianyin+electro-acupuncture group decreased significantly (9.467+ 3.587) ng/ml (P<0.01) , and the number of leptin receptor expression increased considerably (leptin-acceptor masculine cell was 52.30±21.35piece/mm2) (P<0.01). Conclusion The benign regulation of acupuncture combined with traditional Chinese medicine on hypothalamus and serum leptin of obesity body is a significant joint of improving leptin-counteract and abnormal internal hormone metabolism.

Objective To understand and analyse the epidemic status of human intestinal nematode infection in Jiangsu Province, so as to provide basis for making control measures. Methods The typical thirty-nine spots in thirteen counties among the sampling spots of National Investigation on Distribution of Human Parasites in 1990 were selected and investigated according to the Methods of National Investigation Scheme on Human Principal Parasites in 2004. Results The total prevalence was 3.88%, which decreased by 46.92% compared with the investigation in 2002 (7.31%). The infection rates of hookworm, Ascaris and Trichuris were 1.14%, 1.06% and 1.73%, respectively, and the proportion of light infection was 91.75%. The rate of multiple infections was 9.40%. The proportion of hookworm infection was 78.06% in Southern Jiangsu and the proportion of Ascaris or Trichuris was 89.03% in Northern Jiangsu. The infection rate of Enterobius was 3.72% among children aged less than 12 years. Conclusions The prevalence of intestinal nematodes has decreased to lower level in Jiangsu Province. The difference of prevalence in different regions has a relationship with the disease control and social-economic, culture and health levels. The principal control work should be still put in the northern part of Jiangsu Province. The preschool children and the middle and old age peasants are high-risk population. The different control measures should be taken in accordance with the situation of different regions in the future.

Carcinoma of the esophagogastric junction can be radically resected through thorax or abdomen.Because abdominal operation can achieve more ideal abdominal lymph node dissection and less injury of respiratory function,it is ideal for the elderly patients and patients with poor pulmonary function.The classic laparoscopic radical gastrectomy needs a small abdominal incision for making tubular stomach and installation of stapling devices.All the procedures were completed via the main operating trocar.In November of 2011,a 65-year-old male patient with poor pulmonary function and carcinoma of the esophagogastric junction underwent modified total laparoscopic esophagogastric anastomosis.During the operation,the thorax esophagus was mobilized about 5 cm above the esophageal hiatus,then it was pulled to the abdominal cavity and transected.After inserting the OrVil via the mouth,the esophagogastric anastomosis was done.The operation went through smoothly and the procedure was completed conveniently and quickly.The patient recovered well after operation with no local recurrence and metastasis.
