Study on 50 patients (male: 12, female: 38), between the ages of 72 and 40, with hypertension (62% of patients), obesity (60%) in which abdominal obesity (78%) was carried out in Bach Mai Hospital during July 2000- March 2001. The results found that the lipemia disorder frequently occurred in patients with reduced glucose toleration according to the classification of Fredrichson (type IV). 69% patients with the reduced glucose toleration had a lipemia disorder accompanying with hypertension. The risk of hypertension among these patients was higher 6.7 times than this among patients without the lipemia disorder. 93% patients with the reduced glucose toleration and obesity had a lipemia disorder. This rate in the patients with abnormal obesity was 97%; 100% of patients with the reduced glucose toleration had signs of coronary insufficiency

OBJECTIVETo investigate the changes in serum amylase (AMY) and lipase (LPS) and their clinical significance in patients with acute paraquat poisoning (APP).

METHODSThe clinical data of 62 APP. patients who were admitted to Guangzhou 12th People's Hospital in 2014 were retrospectively analyzed. With clinical death being regarded as the end point of observation, the 62 patients were divided into survival group (n=32) and death group (n=30). The fasting venous blood of the patients on the 1st, 3rd, and 7th day after admission were collected, and the AMY and LPS levels were determined; the obtained data were compared between the two groups and analyzed statistically.

RESULTSThe AMY and LPS levels of the survival group on the 1st, 3rd, and 7th day after admission were significantly lower than those of the death group (P<0.05); the AMY and LPS levels of the death group on the 3rd day were significantly higher than those on the 1st day after admission (P<0.05); the survival group demonstrated no significant changes in AMY and LPS levels (P>0.05).

CONCLUSIONChanges in AMY and LPS levels in APP patients are reliable indicators for the determination of poisoning severity and prognosis.

OBJECTIVETo investigate the difference of liver enzyme levels and its correlation with serum ACE/ACE2 among yak and cattle on Qinghai-Tibetan plateau, and to further explore the biochemical mechanism of their liver of altitude adaptation.

METHODSThe serum samples of yak were collected at 3,000 m, 3,500 m, 4,000 m and 4,300 m respectively, meanwhile the serum samples of migrated cattle on plateau (2,500 m) and lowland cattle (1,300 m) were also collected. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), cholinesterase (CHE), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), serum lipase (LPS), angiotensin converting enzyme(ACE), angiotensin converting enzyme-2 (ACE2) in serum were measured by using fully automatic blood biochemcal analyzer. We analysed the differences of the above enzymes and its correlation with ACE/ACE2. We used one way analysis of variance (ANOVA).

RESULTSThe levels of ALT in 4,000 m group and 4,300 m group of yak increased significantly compared with other groups, there were no statistically significant differences in AST, CHE, GGT, ACE/ACE2 levels of yaks at different altitudes. As compared to lowland cattle, the serum levels of AST and CHE were increased, the level of LPS and ACE was decreased significantly, respectively, and especially, the ratio of ACE/ACE2 of migranted cattle reduced nearly two times. The levels of LPS were significantly correlated to the ratio of ACE/ACE2 in yak (r = 0.357, P < 0.01), and a high correlation between ALP and ACE/ACE2 in lowland cattle( r = 0.418, P < 0.05), But the biggest contribution rate of the ratio of ACE/ACE2 was only 17.5% for the changes of the levels of liver enzyme.

CONCLUSIONThe results indicated that with the altitude increased did not significantly influence the changes of liver enzymes' activities in mountainous yaks but not in cattle. However, all above these changes weren't actually correlated to the ratio of ACE/ACE2.

Drug-induced pancreatitis accounts for 0.1~2.0% of all pancreatitis cases. Generally, the mechanism of drug-induced pancreatitis is an immune reaction, accumulation of toxic material, and/or ischemia. However, how dapsone causes pancreatitis remains unclear. A 61-year-old man presented with a 2-week history of epigastric discomfort. He had taken dapsone for 2 months to treat psoriasis. Laboratory findings showed high blood glucose levels and metabolic acidosis; however, hemoglobin A1c was low. Serum amylase and lipase levels were elevated to 125/4,479 U/L. Abdominal computed tomography was indicative of pancreatitis. There was no causative history of pancreatitis and no other medication history except dapsone. Thus, we reached a diagnosis of diabetic ketoacidosis (DKA) followed by dapsone-induced pancreatitis. The patient fasted and was treated with insulin administration and fluid hydration in accordance with treatment guidelines. After treatment, amylase and lipase decreased and symptoms subsided, but insulin injection was required to control blood glucose levels. Drug-induced pancreatitis is a very rare adverse effect of dapsone. Only four cases of pancreatitis related to dapsone could be found in a PubMed search. Moreover, diabetes caused by dapsone-induced pancreatitis has not been reported previously. Here, we report a case of DKA caused by dapsoneinduced acute pancreatitis.

Lipoprotein lipase (LPL) is known to be attached to the luminal surface of vascular endothelial cells in a complex with membrane-bound heparan sulfate, and released into blood stream by heparin. LPL that catalyzes hydrolysis of triglyceride (TGL) on chylomicron and VLDL into two fatty acids and monoacylglycerol, is also implicated to participate in an enhancement of cholesterol uptake by arterial endothelial cells in vitro. But little is known about the LPL-mediated cholesterol uptake in physiological state. In this study, changes in blood lipid composition and levels of lipoproteins were determined after the injection of heparin in human. The level of LPL in plasma was increased from 0 to 11 mU/ml within 30-40 min post-heparin administration and decreased to the basal level within 2 h. The level of TGL in plasma decreased from 70 mg/dl to 20 mg/dl within 1 h and gradually increased to 80 mg/dl within 4 h. However the level of total cholesterol in plasma remained at 140 mg/dl during an experimental period of 4 h. Analysis of Lipoproteins in plasma by NaBr density gradient ultracentrifugation showed that the level of VLDL decreased from 50 mg/dl to 10 mg/dl within 1-2 h and returned to normal plasm level at 4 h. However there were no significant changes in the level of LDL and HDL. These results suggest that, at least, in normo-lipidemic subjects, increased free plasm LPL acts primarily on VLDL and failed to show any significant uptake of cholesterol-rich lipoproteins in human.

OBJECTIVETo observe the effects of Yifuning (YEN) capsule on blood lipids of ovariectomized hyperlipidemia rats.

METHODFifty-six female mature Sprague-Dawley rats were randomized into 7 groups: normal control group, model control group, diethylstilbestrol tablets (DT) group, Xuezhikang group, YFN high, middle and low dose groups. The ovariectomized rats were fed on high fat diet and administrated with the drugs for 3 weeks, then were killed and estimated body weight, liver index and five items of blood lipid (TC, TG, HDL-C, LDL-C, VLDL) by test kit. Enzyme (such as HP, LDL, and whole lipase) was detected too.

RESULTThe weight and liver index of model control group increased obviously as compared with normal group. YFN could reduce TG, TC, and LDL-C (P < 0.05) of ovariectomized hyperlipidemia rats obviously and increase HP, LDL and whole lipase (P < 0.05) on the other hand.

CONCLUSIONYFN can ameliorate blood lipids of ovariectomized hyperlipidemia rats.

BACKGROUND/AIMS: Increased levels of pancreatic enzymes have been reported in patients with renal insufficiency even in the absence of pancreatic diseases. Here, we analyzed serum amylase and lipase levels in chronic renal failure patients according to the degree of azotemia and the treatment modality. METHODS: Serum amylase and lipase levels were reviewed in 95 patients on continuous ambulatory peritoneal dialysis, 105 patients on hemodialysis, 71 patients with renal transplantation, and 73 patients without treatment. Age and sex matched 344 normal healthy controls were selected among those who checked their serum amylase and lipase levels during the same study period. RESULTS: Mean value of amylase level in the patient group (93.7+/-76.5 U/L) was higher than healthy controls (63.8+/-21.4 U/L) (p<0.001) and lipase level in the patient group (212.3+/-195.0 U/L) was higher than healthy control (95.2+/-45.1 U/L) (p<0.001). There was no significant difference in amylase and lipase levels according to the treatment modality in the patient group. The correlations between creatinine clearance and amylase (r=-0.148, p=0.012) or lipase (r=-0.119, p=0.042) were found to be inverse only when the creatinine clearance falls below 50 mL/min. CONCLUSIONS: Serum amylase and lipase levels are about 1.5 times and 2.2 times higher in chronic renal failure patients than healthy controls regardless of treatment modality. The elevations of amylase and lipase levels are inversely correlated with creatinine clearance when it falls below 50 mL/min.

3'-Deoxyadenosine, so-called cordycepin, is a bioactive component of the fungus Cordyceps militaris. It has been known to exhibit multiple-biological effects including: modulation of immune response, inhibition of tumor growth, hypotensive and vasorelaxation activities, and promoting secretion of adrenal hormone. To investigate its lipid-lowering effect, hyperlipidemic hamsters and rats fed by high-fat diet were both administered orally with cordycepin extracted from Cordyceps militaris for four weeks. The levels of lipids in hamsters and rats were measured enzymatically before and after the administration of cordycepin (12.5, 25 and 50 mg x kg(-1)). The results suggested that levels of serum total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) increased markedly in the two animal models by feeding high-fat diet. Meanwhile, cordycepin reduced levels of serum TC, TG, LDL-C, VLDL-C as well as LDL-C/HDL-C (high density lipoprotein cholesterol) and TC/HDL-C ratios. In concert with these effects, an increase in lipoprotein lipase (LPL) and hepatic lipase (HL) activity afforded by cordycepin was considered to contribute to the regulation on lipid profiles. Furthermore, no toxicity of cordycepin was observed by intragastric administration at the maximal tolerant dose in ICR mice for 14 days. The exact lipid-lowering effect of cordycepin needs further investigation.

Pancreatitis has been occasionally associated with Crohn's disease (CD). A definite etiology of pancreatitis can be identified in most patients, but a very small proportion remain idiopathic. We report a case of idiopathic pancreatitis resolved along with the clinical improvement of CD in a 25-year-old man. He presented with abdominal pain and diarrhea for 8 years. Ileocolonoscopy and enteroclysis showed multiple, longitudinal ulcers and strictures at the ileojejunum. The laboratory findings showed elevated serum amylase (951 IU/L) and lipase (326 IU/L) without positive autoantibodies. Esophagogastroduodenoscopy, enhanced pancreatic CT, and MRCP showed no abnormalities at ampulla of Vater, pancrease, and pancreaticobiliary duct. With the treatment with antibiotics, 5-aminosalicylic acid, steroid, and azathioprine, as a whole, decreasing pattern and intermittent fine coordinated fluctuation of the levels of amylase and lipase along with the decrease of Crohn's disease activity index (CDAI) and the CRP levels were observed. Then, three months after the start of the treatment, normalization of the pancreatic enzymes was observed, and there was recurrent elevation of pancreatic engyme during 12 months maintenance therapy. This report supports the concept of an association between idiopathic pancreatitis and CD, based on a significant and close relation between the levels of serum amylase and lipase, and CDAI.
