Objective To explore influence of thoracic duct ligation on lipid metabolism after esophagectomy. Methods Seventy-four patients with esophageal cancer received esophagectomy were divided into two groups by their thoracic duct ligation, 39 in ligation group and 35 in non-ligation group. All the patients were fed with nutrients through nasal-duodenal tube placed during operation from the 1 st day to the 8th day after surgery, and started taking liquid diet on the 6th day. Blood specimens were collected from the patients on the 1st day after admission, the 9th day, one month and three months after surgery,respectively for biochemical analysis,including determinations of total cholesterol(TC),triglyeeride(TG),high-density lipoprotein-cholesterol ( HDL-C) and low-density lipoprotein-cholesterol ( LDL-C) . Databetween the two groups were compared with statistical analysis. Results No significant difference in plasma levels of TC, TG and HDI.-C was found between the two groups at varied time points. Plasma level of LDL-C in the ligation group significantly decreased on the 9th day after surgery, as compared with that in the nonligation group ( P < 0. 05), and went down to the lowest level one month after surgery. Conclusions Chylomicron was blocked to enter blood stream and production of LDL-C decreased by thoracic duct ligation,which affect lipid absorption and metabolism leading to poor early nutrition in patients with esophagealsurgery due to slower establishment of collateral circulation.

Objective To evaluate the endoscopic managements of acute cholangitis of severe type (ACST) accompanied with multiple organ dysfunction syndrome (MODS). Methods A total of 122 ACST patients accompanied with MODS from January 2000 to October 2008 underwent endoscopic treatment in two time periods. In critical phase, emergent endoscopic retrograde cholangiopancreatography (ERCP) plus en-doscopic naso-biliary drainage (ENBD) were performed to correct critical situation of the patients. After sta-bilization, endoscopic sphincterotomy (EST) plus stone removal, EST plus stent placement, or laparoscopy was performed according to the causes of ACST. Results Emergent endoscopic managements succeeded in all patients of critical phase. At third day post-operation, a reduction in white blood cell count, serum total bilirubin, body temperature, and rate of patients with shock, mental symptoms and purulent bile juice was a-chieved. Recovery rate of dysfunction organs was 60.2% at one week after emergent procedure, and 82. 6% at 2 weeks post-operation. Selective EST plus stone removal was performed in 36 patients with a success rate n one session at 91.7%. Laparoscopic cholecystectomy was performed in 85 patients with a success rate of 95.3%. Stent was placed in 16 patients with an effective rate of 81.3% at 3 months post the procedure. No severe complication or death occurred during the whole therapeutic course. The 6-month survival rate of 10 cancer cases was 70%. Conclusion Therapeutic ERCP plus ENBD is the first choice for acute severe cholangitis accompanied with MODS, while EST plus biliary lithotomy, or EST plus stent placement, or com-bined laparoscopy are ideal methods for subsequent treatment.

Objective To investigate the effects of Dangshen (DS) extract saponins alleviating apoptosis in ischemia-reperfusion injury (I/R) of renal grafts and the mechanism. Methods The I/R injury model in SD rats was established after kidney transplantation. The SD rats were randomly divided into the following 3 groups (n = 20): sham operation group, I/R model group, DS saponin intervention group. Blood urea nitrogen (Bun) and creatinine (Scr) levels were determined at the 24th h after operation; apoptosis index (AI) was detected by using TUNEL method; the expression of Bcl2 and bax mRNA was detected by RT-PCR. Results As compared with the sham operation group,the blood Bun and Scr levels were significantly increased in the I/R model and DS saponin intervention groups (P<0. 05). As compared with the DS saponin intervention group, the blood Bun and Scr levels were significantly increased in the I/R group (P<0.05). The AI was significantly increased in the I/R model group and DS saponin intervention group. After DS saponin intervention, the AI was decreased from 40. 28 % in the I/R model group to 28. 45 % in the DS saponin intervention group (P<0. 05). The expression of Bcl-2 mRNA in DS saponin intervention group and I/R model group was significantly decreased as compared with the sham operation group (P<0. 05), but that of Bax mRNA was significantly increased in the I/R model group and DS saponin intervention group as compared with the sham operation group (P<0. 05). After DS saponin intervention, the expression of Bcl-2mRNA was increased from 0. 25 in the I/R model group to 0. 391 (P<0. 05), and that of Bax mRNA was decreased from 0. 565 in the I/R model group to 0. 473 (P<0. 05). Conclusion DS extract saponin could significantly alleviate apoptosis in the I/R injury of renal grafts possibly by up-regulating the expression of Bcl-2 mRNA and down-regulating the expression of Bax gene.

The method of flying through the air is a qi-promoting and qi-circulating technique commonly used in clinical acupuncture. It includes four methods: the blue dragon wagging its tail, the white tiger shaking its head, the green turtle probing the cave and the red phoenix winging to the source and functions to circulate bodily meridian qi. The method of flying through the air was firstrecorded in Golden needle Fu. Later and modern doctors developed it on the basis of Golden needle Fu. This article straightens up the historical origin and development of four methods of flying through the air.
