Objective By observing the effect of Xiaoyuhuatan decoction on insulin resistance in rar with nonalchoholic fatty liver,the author made a reasearch into this herb'S machanism on cambating on nonalchoholic fatty liver.Methods The insulin resistance rat model was fed by high fat forage and Dongbaogantai control group was set up for the sake of comparion.We determined the contents of total cholesterol(TC),triglyceride(TG),free fatty acid(FFA),fasting plasma glucose(FBG),fasting serum insulin(INS)in serum and the contents of TC,TG of liver tissue homogenate of each group,and the degree of hepatocytic steatosis.Results Xiaoyuhuatan decoction could obviously decrease the index of insulin resistance and improve insulin insensitive index.Lipid in blood serum and hepatic tissues were significantly decreased,liver fat cell denaturation was improved.Conclusion The thrapentic eftect of Xiaoyuhuatan Decoction on fatty liver is probably contribute tO this herb's mechanism of improving insulin resistance and increasing insulin insensitive.

Objective To explore the techniques of renal transplantation in diabetic recipients with lilac atherosclerosis.Methods Overall,54 renal transplantations were performed in 51 diabetic recipients with lilac atherosclerosis.The renal arteries were end-side anastomosed to iliac arteries with atherectomy in 19 cases and without atherectomy in 13 cases,or end-end anastomosed to internal iliac arteries through titani- um stapler after atherectomy in 22 cases.Results Primary nonfunetion of renal allografts occurred in 3 cases due to poor blood perfusion of the renal grafts;delayed graft function occurred in 9 cases(17.6%), and the other 42 grafts functioned well immediately after transplantation.Two patients died of sudden cardiac arrest during the perioperative period.During a follow-up of 11-70 months,the 1-year and 3-year survival rates of recipients/grafts were 89.8%/87.8% and 84.4%/81.3% ,respectively.The main cause of graft loss was recipients' death with functioning graft.Conclusions The artery anastomosis of renal graft in di- abetic recipients with lilac atherosclerosis is difficult to perform.In order to achieve enough blood peffusion of the renal graft,it is important to select proper artery for anastomosis and to perform atherectomy.The recipi- ents with coronary artery disease should receive myocardial revascularization routinely before transplantation.

OBJECTIVETo analyze the ageing and related risk factors affecting the death rate of diabetes mellitus in Beijing, and make a correct assessment of risk factors in changing the death rate of diabetes mellitus.

METHODThe changes of death rate on diabetes mellitus in the past 10 years, from 1991 to 2000 were analyzed and calculated as to making clear what is the effects resulting from the ageing and the risk factors.

RESULTSThe death rate of diabetes mellitus was increased to 117.55%, from 1991 to 2000, in which 53.28% were attributing to the ageing and 46.72% to the risk factors.

CONCLUSIONThe effects of ageing and risk factors on death rate of diabetes mellitus should be different and the ageing should be a factor more important than the other risk factors.

Derris eriocarpa, a traditional Chinese medicine belonging to the family of Leguminosae, is widely distributed mainly over Yunnan, Guangxi and Guizhou of China. Modern pharmacological researches on this herb showed that it had extensive bioactivities, such as promoting urination, removing dampness and cough and reducing inspissated mucus and other biological activities. The extensive studies on the chemical constituents of this plant have resulted in the isolation of triterpenoids, steroids, fatty acid and others, but the flavone compounds haven't reported before. In our further research on the ethyl acetate of this plant, nine flavone compounds were obtained by column chromatography on silica gel, Sephadex LH-20, semi-prep HPLC, polyamide column chromatography and recrystallization for separation and purification. The structures were determined on the basis of extensive spectroscopic analysis, including MS, NMR experiments and comparison with spectroscopic data in the literature, respectively, as diosmetin (1), 3, 3'-di-O-methylquercetin (2), afromosin (3), 6, 3'-dihydroxy-7, 4'-dimethoxyisoflavone (4), odoratin (5), 7, 3'-dihydroxy-8, 4'-dimethoxyisoflavone (6), 6, 4'-dihydroxy-7, 3'-dimethoxyisoflavone (7), 5, 7, 4'-trihydroxy-3, 3', 5'-trimethoxyflavone (8), and alpinumisoflavone (9). All these compounds were isolated from Derris eriocarpa How for the first time. And the in vitro assays showed that compound 2 possessed moderate inhibitory activity against human cancer cells K562 and HEL.

OBJECTIVETo explore the distribution laws of TCM syndrome types and to analyze the distribution of dynamic blood pressure curve, atherosclerosis, and age in senile hypertension patients.

METHODSTotally 1 131 senile hypertension patients were recruited from 7 provinces and municipal cities. Features of TCM syndromes, classification and distribution curves, and syndrome distribution laws were observed. The distribution curves of dynamic blood pressure, carotid atherosclerosis, and age were compared in each TCM syndrome types.

RESULTSThere were four main syndrome types in 736 cases (56.15%), i.e., excessive accumulation of phlegm-dampness syndrome (210 cases, 16.02%), yin deficiency and hyperactivity of yang syndrome (177 cases, 13.50%), Gan-Shen yin deficiency syndrome (79 cases, 6.03%), and deficiency of qi and yin syndrome (252 cases, 19.22%). Besides, there were two more sub-types, i.e., collateral obstruction by blood stasis syndrome and collateral obstruction by phlegm and stasis. Circadian blood pressure monitor was completed in 211 cases. Of them, abnormal circadian blood pressure occurred in 152 cases (accounting for 72. 38%); yin deficiency and hyperactivity of yang syndrome, excessive accumulation of phlegm-dampness syndrome, deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome were most often seen. Color ultrasound of carotid artery was performed in 660 patients of main syndromes. The incidence was quite higher in those of excessive accumulation of phlegm-dampness syndrome (182 cases, 27. 58%), deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome or collateral obstruction by phlegm and stasis (322 cases, 48.79%). Yin deficiency and hyperactivity of yang syndrome was dominant in patients 60 -79 years old, while deficiency of qi and yin syndrome and Gan-Shen yin deficiency syndrome were dominant in patients older than 80 years.

CONCLUSIONSExcessive accumulation of phlegm-dampness syndrome, yin deficiency and hyperactivity of yang syndrome, Gan-Shen yin deficiency syndrome, and deficiency of qi and yin syndrome were main syndrome types in senile hypertension patients. There was statistical difference in the distribution curves of blood pressure, atherosclerosis, and age of various TCM syndrome types.

OBJECTIVETo evaluate the effects of selective hepatic vascular exclusion (SHVE) on prevention of serious hemorrhage and air embolism during hepatectomy and on the liver function after operation.

METHODSFrom January 2004 to March 2007, 29 huge hepatic tumors were resected in our department. Both SHVE and Pringle maneuver were used to control the blood loss during hepatectomy. They were divided into two groups: SHVE group (15 cases) and Pringle group (14 cases). Data regarding the intraoperative and postoperative courses of the patients were analyzed.

RESULTSThere was no significant difference between the two groups regarding the age, sex, tumor size, cirrhosis, HbsAg positive rate and operating time (P > 0.05). Intraoperative blood loss was reduced significantly in the SHVE group (P < 0.05). The serum prealbumin levels on the postoperative day 1, 3 and 7 in SHVE group were significantly higher than those in the Pringle group (P < 0.05). The serum ALT value in SHVE group was significantly lower than that in the Pringle group on postoperative day 1, 3 and 7. The mean drainage volume in SHVE group was significantly less than that in the Pringle group on postoperative day 1 and 2. Liver failure occurred in two cases of the Pringle group, while no one in the SHVE group. Rupture of hepatic vein with massive blood loss occurred in 3 cases and air embolism in one case of the Pringle group, but did not occur in any case of the SHVE group.

CONCLUSIONWhen the selective exclusion of hepatic outflow and inflow is applied in hepatectomy, the resection rate of huge hepatic tumors and operative tolerance of hepatectomy are improved. It is a safe and rational operation type, and provides an optimal choice for hepatectomy.

OBJECTIVETo analyze the characteristics of out-of-hospital acute coronary heart disease (CHD) deaths in Beijing permanent residents at the age of 25 or more from 2007 to 2009.

METHODSWe analyzed the gender, age, geographical distribution, occupation, marital status and the extent of different education characteristics of out-of-hospital acute CHD deaths of the Beijing permanent residents at the age of 25 or more from 2007 to 2009 using the mortality information database from the Beijing Vital Registration Monitoring System.

RESULTSOf the total 41 732 acute CHD deaths, 30 159 (72.27%) died out of hospital and out-of-hospital mortality was 2.61 times higher than in-hospital mortality. Majority out-of-hospital death occurred in males (72.30%, 16 068/22 224), in 25 - 34 years old people (91.75%, 89/97), in residents living in remoter suburbs and counties (82.43%, 13 513/16 393), in rural population (89.50%, 10 017/11 192), in non-marital single (80.76%, 592/733) and in people less than five-years of schooling (83.95%, 11 388/13 565). Most out-of-hospital acute CHD death occurred at home (78.80%, 23 765/30 159).

CONCLUSIONSOut-of hospital acute CHD mortality is high in Beijing permanent residents at the age of 25 and over from 2007 to 2009. Male, 25 - 34 years old, living in outer suburbs and counties, rural population, non-marital single, and less education years are major risk factors for out-of-hospital acute CHD death.

Objective To evaluate interventional therapy for biliary stricture (BS) after orthotopic liver transplantation (OLT). Methods The efficacy of interventional therapy for BS after OLT from Oct 2003 to Jan 2006 was analyzed retrospectively. Fifty-three patients received 107 times of interventional therapy through endoscopic retrograde cholangiography ( ERC) which included 68 nasobiliary catheter placements,26 biliary balloon dilatations and stent placements and 13 ERC. Nine patients received 11 times of interventional therapy through percutaneous transhepatic cholangiography ( PTC) including 2 PTC, 7 percutaneous drainages,3 biliary balloon dilatations and 1 biliary stent replacement. One patient received bile drainage through T tube. Results The success rate of ERC was 88. 8% (95/107) , that of nasobiliary catheter placement 94% (64/68) , biliary stent placement 88. 5% (23/26). The success rate of PTC was 81. 8% (9/11) , that of percutaneous drainage was 100% (7/7) , biliary stent replacement 100% (1/1). The curative rate of interventional therapy for 53 patients with BS was 28. 3% (15/53) ,the improvement rate was 41. 5% (22/53). The curative rate of interventional therapy for anastomotic, extrahepatic, intrahepatic hilar and diffuse BS was respectively 66. 7% (4/6)、66. 7% (10/15)、50% (1/2)、0 (0/7) and 0 (0/22). Conclusions The efficacy of interventional therapy for BS after OLT was not satisfactory. The result relates to the type of BS, for anastomotic, extrahepatic and solitary intrahepatic BS this therapy was effective, while that for hilar and diffuse BS the prognosis was poor.
