The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome (MODS) were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO(2) were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (P<0.05), but the level of serum albumin was significantly increased (P<0.05) at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 (P<0.01) after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (P<0.01). The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.

Tetrazanbigen (TNBG) is a novel synthetic antitumor drug with significant antitumor effects on common solid tumors in vitro and in vivo. It may lead to death of cancer cells through a tumor-associated lipoidosis mechanism, and result in lipid droplets (LDs) accumulation at the cytoplasm. In this study, the effects of TNBG on protein expression in human hepatocellular carcinoma cell line QGY-7701 were studied for elucidating its antitumor mechanism. The proteins extracted from TNBG-treated human hepatocellular carcinoma cell line QGY-7701 were analyzed and compared with control cells by two-dimensional gel electrophoresis. The differential proteins were identified by matrix-associated laser desorption ionization time-of-flight mass (MALDI-TOF-MS) spectrometry. Two proteins of interest, the levels of which were significantly increased in TNBG-treated cells, were further characterized by Western blot analysis. The results showed a total of 846+/-23 spots in control cells and 853+/-30 spots in TNBG-treated cells. Twenty-six up-regulated or down-regulated proteins were found by analyzing differential proteomic 2-DE map. Eleven of them were identified by mass spectrometry. They were protein disulfide-isomerase precursor, 94 kD glucose-regulated protein, heat shock protein (HSP) 90-alpha, ATP-citrate lyase, HMG-CoA reductase, glucose-6-phosphate 1-dehydrogenase, very-long-chain specific acyl-CoA dehydrogenase, squalene synthetase, sterol regulatory element-binding protein 1, fructose-bisphosphate aldolase A, and peroxiredoxin-1. These up-regulated or down-regulated proteins are mostly related to lipid metabolism. The TNBG antitumor mechanism is probably to influence tumor lipid metabolism, resulting in accumulation of LDs in tumor cells.

OBJECTIVETo summarize the clinical features, biochemical change and genetic mutations of a neonate with congenital bile acid synthesis disorder type 2.

METHODSClinical features, blood biochemical index, gene analysis and treatment of the patient were reviewed.

RESULTSThe patient presented with the symptoms of jaundice 3 days after birth but without skin itching. Pale stool was noted. Subsequently, he presented with hepatomegaly, blood coagulation disorders, left cochlear nerve damage, liver cirrhosis and remarkable growth retardation. Serum biochemistries showed that bilirubin and transaminase were elevated, while γ -GT and total bile acid was normal. Abdominal ultrasonography indicated decline of gallbladder contraction. Cholangiography showed normal extra- and intrahepatic bile ducts and patent biliary tract. Liver biopsy showed intrahepatic cholestasis. Gene testing has identified a homozygous mutation in AKR1D1 gene.

CONCLUSIONCongenital bile acid synthesis disorder should be suspected when a neonate has presented with jaundice, elevated bilirubin and transaminase, normal or reduced TBA and γ -GT. Genetic testing and urine mass spectrometry analysis can diagnose congenital bile acid synthesis disorder. Early therapy is crucial to patients with congenital bile acid synthesis disorder.
