AIM： To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age and gender-matched control subjects.METHODS： We recorded duration of diabetes and examined fasting glucose levels, HbAlc levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls. Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups.RESULTS： The average CA 19-9 level was 46.0 ± 22.4 U/mL for diabetic patients whereas it was 9.97± 7.1 U/mL for the control group （P 〈 0.001 ）. Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age, gender, glucose level and HbAlc level （t = 8.8, P 〈 001 ）. Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation. For all patients, abdominal CT showed no pancreatic abnormalities. CONCLUSION： CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic, upper gastrointestinal tract, ovarian hepatocellular, and colorectal cancers, as well as in inflammatory conditions of the hepatobiliary system, biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer, which is increasing its incidence and has one of the lowest survival rates of all cancers. CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes. We propose that a higher cutoff value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction.

Sirolimus is an immunosuppressant with expanding use in pediatric organ transplantation, dermatology and rheumatology. We report two cases of children who developed asthma like symptoms and were diagnosed with interstitial lung disease, which responded to discontinuation of sirolimus. Pediatricians should be aware about the pulmonary side effects of sirolimus.

AIM, To study the role of N-acetylcysteine （NAC） as a protective agent in rifampicin （RMP）-induced oxidative hepatic injury of young rats. METHODS： Hepatic injury was produced by giving 50mg/kg body weight/day of RMP for 3 wk. A dose of NAC （100mg/kg body weight/day） was given in combination with RMP intraperitoneally. Analysis of lipid peroxidation, thiol levels, cytochrome P4se, superoxide dismutase （SOD）, catalase, glutathione peroxidase, reductase and transferase were estimated in liver along with the body weight, liver weight and histological observations. RESULTS： RMP exposure resulted in no change in body and liver weight while antioxidative enzymes were altered but the non protein thiol （GSH） status was well preserved. Cytochrome P450 system and peroxidation of lipids were induced by RMP exposure. Partial protection was observed with NAC against RMP-induced changes in liver, which was evidenced from the prevention of increase in lipid peroxidation and the reduction in SOD and catalase enzyme levels. CONCLUSION. NAC protects young rats against RMP- induced oxidative hepatic injury.

对分别在(-2～0)℃和20℃两种温度下热泵干燥北极虾(整虾、去头北极虾、去壳北极虾)的物理和感官特性进行了研究。结果显示,当热泵干燥温度由(-2～0)℃增加到20℃时,干燥虾的收缩率和所需的剪切力增大。干燥温度对干燥虾的色泽影响不显著。所有热泵干燥虾均具有高的复水能力和水分保持能力(WHC)。研究结果还显示,虾的处理状态(有壳或无壳、有头或无头、解冻处理)对其物理和感官特性有着显著影响。解冻处理不利于虾色泽的保持并使之收缩增加。在所有的干燥虾样品中,在20℃下干燥的冷冻去头虾(B-2)具有最好的综合表现。与热风干燥相比,利用热泵干燥虾可获得高质量干燥产品。

We present coupled ocean-sea-ice simulations of the Middle Jurassic（~165 Ma） when Laurasia and Gondwana began drifting apart and gave rise to the formation of the Atlantic Ocean. Since the opening of the Proto-Caribbean is not well constrained by geological records, configurations with and without an open connection between the Proto-Caribbean and Panthalassa are examined. We use a sea-floor bathymetry obtained by a recently developed three-dimensional（3D） elevation model which compiles geological, palaeogeographical and geophysical data. Our original approach consists in coupling this elevation model, which is based on detailed reconstructions of oceanic realms, with a dynamical ocean circulation model. We find that the Middle Jurassic bathymetry of the Central Atlantic and Proto-Caribbean seaway only allows for a weak current of the order of 2 sv in the upper 1000 m even if the system is open to the West. The effect of closing the western boundary of the Proto-Caribbean is to increase transport related to barotropic gyres in the southern hemisphere and to change water properties, such as salinity, in the Neo-Tethys. Weak upwelling rates are found in the nascent Atlantic Ocean in the presence of this superficial current and we discuss their compatibility with deep-sea sedimentological records in this region.
