Objective To evaluate the diagnostic significance of ECG and coronary arteriography (CAG) in coronary heart disease in different age groups. Methods totally 216 cases of suspected or CAG-confirmed coronary heart disease were retrospectively analyzed. The non-elderly group included patients aged 45-59 years, and the elderly one was older than 60. Patients in each group were further divided into subgroup A and B with or without the pain in heart front area, respectively, accompanied by ST-T change in ECG. Comparative analysis of CAG and ECG changes was done between different age groups, and between subgroup A and B. The history of pain in heart front area, serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), platelet count (PLT), and fibrinogen (Fg) were also analyzed for clinical diagnosis. Results In the non-elderly, positive CAG was 88.8% in subgroup A while 56.3% in group B ( P0.05). TC, LDL-C, and Fg were significantly higher in subgroup A than in subgroup B for the elderly group. But in non-elderly, TC, TG, LDL-C, and Fg in subgroup A were significantly higher than those in subgroup B(all P0.05). The history of pain in heart front area was longer in the elderly, and also in this age group, more patients showed multivessel involvement. Conclusions ST-T change of ECG accompanied by classical pain in heart front area is more valuable than single ST-T change in the diagnosis of coronary heart disease, especially among non-elderly patients. ST-T change could not be used simply as a tool to diagnose coronary heart disease. The diagnosis should be made generally considering the typical symptom of the pain in heart front area, clinical history, TC, TG, LDL-C, and Fg. CAG could increase the positive diagnostic rate of coronary heart disease and decrease the rate of misdiagnosis as well.

Gindenosides are the active ingredients of Panax ginseng. 20 (S) -protopanaxadiolocotillol type epimers are the main metabolites of 20 (S) -protopanaxadiol. The previous studies showed that there are stereoselectivity difference in pharmacodynamics and pharmacokinetics between 24R-epimer and 24S-epimer. The purpose of this study was to explore the excretion of the epimers in bile, feces and urine of rat. Liquid chromatography tandem mass spectrometry method has been performed for determination of 24R-epimer and 24S-epimer in bile, feces and urine. 24R-epimer or 24S-epimer was intragastric administered to rats at a single dose of 10 mg x kg(-1). Results showed that after administration the recovery of 24R-epimer and 24S-epimer in feces was 17.69% and 17.09%, respectively, while both of the two epimers were hardly detected in urine. The 48 h cumulative biliary excretion rate of 24R-epimer was 8.01% after administration, while only 1.47% for 24S-epimer. It indicated that there are stereoselectivity in biliary excretion of the epimers with intragastric administration.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.
METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.
RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).
CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.

Objective To discuss the perioperative management of cirrhotic patients undergoing abdominal operation. Methods From Jan. 2000 to Jul. 2007, 93 patients with PHT underwent operation in our hospital. We retrospectively analyzed the data according to different therapy result. Results 21 cases developed postoperative ascites. The occurrence of ascites in patients dealt with PHT and coexistent other abdominal disease was 7% and 12% respectively for Child A and B grade patients. The occurrence of ascites in patients dealt with only abdominal disease was 13% and 17% respectively for Child A and B grade patients. The occurrence of ascites in patients dealt with PHT and abdominal disease was amazingly 83% for Child C cases. Patients suffered from tumors didn't have more risk of ascites than the other patients. Conclusion The proper perioperative management of patients can decrease the mortality. To deal with PHT together with abdominal operation is reasonable for patients in Child A or B liver function, and it would not increase the postoperative ascites. For the selective patients, we must try our best to decrease the ascites preoperatively to improve the condition.

Objective To study the development of cardiomyopathy complicated with type 2 diabetes mellitus in the rats. Methods The 120 health male Sprague-Dawley rats, weighing 180-220 g, were divided into 4 groups: (1)STZ-modeled diabetes, fed with high-carbohydrate plus high-fat diet (n=40);(2)fed with regular diet (n=30);(3)and (4)SD rats with citrate buffer instead of STZ injection, fed with high-carbohydrate and high fat diet (n= 25);and fed with regular diet (n= 25); At the 4th, 8 th, 12 th and 16 th week after the intra-peritoneal injection of STZ solution or citrate buffer solution, rats from each group were scarified and examined. Results There were no significant differences in body mass and blood glucose among those groups after one week of feeding (P>0. 05).After 4 weeks of feeding before injection, the body mass, fasting insulin (FINS) and insulin sensitive index (ISI) were obviously increased in diabetes group and high-carbohydrate plus high-fat control group as compared with STZ control group and normal control group (P< 0. 05). There were no significant differences between diabetes group and high-carbohydrate plus high-fat control group,between STZ control group and normal control group (P>0. 05). After injection, the blood glucose,body mass, ventricular mass, TG and TC were higher in diabetes group and high-carbohydrate plus high-lipid control group than in STZ control group and normal control group (P<0.05). The above parameters were much higher in diabetes group than in high-carbohydrate plus high-lipid control group, but there was no difference between STZ control group and normal control group (P<0. 05).Pathological examination showed that the weight of the heart was significantly increased, the myocardial cells were hypertrophied accompanying degenerative changes and apoptosis, the interstitial collagen fibers were hyperplasia in the diabetic rats. The ultrastructures also presented severe damage.These changes indicated that cardiomyopathy was induced in the diabetes rats. Although similar changes were found in the rats fed with high-carbohydrate plus high-fat diet, they were much less significant than those in the diabetic rats. Conclusions Cardiomyopathy developes frequently in the rats with type 2 diabetes mellitus induced by feeding high-carbohydrate plus high-lipid diet and single intra-peritonial injection of 30 mg/kg STZ solution.

Objective To assess the clinical value of high-frequency electrocautery in the treatment of massive hemorrhage of presacral venous plexus. Methods The clinical data of 8 patients with presacral venous hemorrhage treated with high-frequency electrocautery from February 2005 to March 2008 were analyzed. Once the presacral venous hemorrhage happened, the bleeding site was pressed with a gauze or finger and the accumulated blood was aspirated. Then, while simultaneously withdrawing the gauze or finger over the bleeding sites, high-frequency electrocautery was applied with a power of 80-100 W to coagulate all the bleeding sites. Results High-frequency electrocautery was used to stop bleeding in the 8 patients, and no electrocautery related complica-tions occurred postoperatively. Conclusions High-frequency electrocautery for massive hemorrhage of presacral venous plexus is simple, efficient and safe.
