Objective To observe the effect of duration of carbon dioxide pneumoperitoneum on coagulation, fibrinolysis and endothelial activation in elderly patients undergoing laparoscopic cholecystectomy (LC). Methods The 45 elderly patients with cholelithiasis scheduled for LC, aged over 60 yeas, were placed in different groups respectively after surgery according to the duration of pneumoperitoneum. The duration of pneumoperitoneum was ≤60 minutes in group A (n=21),and more than 60 minutes in group B (n=24). Venous blood samples were taken on admission (baseline), at the end of surgery, the 1st, 2nd and 3rd day after surgery for determination of prothrombin time (PT), activated partial thromboplastin time (APTT), prothrombin fragment F1+2 (F1+2), antithrombin 3 (AT-Ⅲ activity), fibrinogen (Fib), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-1), D-dimer (D-D), von Willebrand factor (vWF activity). Results Concerning the coagulation activation, at the 3rd postoperative day, the level of F1+2 was significantly higher in group B than in group A [(1.60±0.26) μg/L vs. (1.32±0.24) μg/L, P<0.05]; AT-III was significantly higher in group B than in group A [(84.82%±20.21%) vs. (97.49%±16.87%), P<0.05]. At the 2nd and 3rd postoperative day, the levels of Fib were significantly higher in group B than in group A [(3.87±0.62) g/L vs. (3.42±0.72) g/L, (3.98±0.77) g/L vs. (3.42±0.63) g/L, respectively, P<0.05]. Concerning fibrinolysis, But at the 2nd and 3rd postoperative day, the level of PAI-1 was significantly higher in group B than in group A [(33.93±10.42) μg/L vs. (26.69±9.49) μg/L, (32.90±11.25) μg/L vs. (26.31±7.06) μg/L respectively, P<0.05]. Concerning endothelial activation, at the 2nd and 3rd postoperative day, vWF was significantly higher in group B than in group A [(174.53%±44.03%) vs. (134.37%±37.74%), (176.31%±47.6%) vs. (131.21%±36.34%), respectively, P<0.05]. Conclusions Marked activations of coagulation-fibrinolysis and endothelial activation are observed postoperatively in elderly patients undergoing laparoscopic cholecystectomy. Along with prolonged duration of pneumoperitoneum, more pronounced alterations of increased coagulation, reduced fibrinolysis and endothelial activation are observed, which could constitute an imbalanced situation of coagulation-fibrinolysis and increases the risk of venous thrombosis.

AIM: Abnormal hyperphosphorylation of tau plays a critical role in the pathogenesis of Alzheimer's disease(AD), and tau protein was hyperphosphorylated in type 2 diabetes. The present study was designed to explore the phosphorylation level of tau in hippocampus of type 2 diabetes rats which interrupted by very low density lipoprotein receptor(VLDLR)gene transfection. METHODS: Wistar male rats were randomized into 3 groups. The control group(CTL)was fed with normal food. The T2DM group and T2DM mediated VLDLR gene group were on high sugar, high fat and high protein diet for 3 months. The plasma insulin level was measured by RIA method, and the plasma glucose was determined by glucose-oxidase method. Total tau level, the phosphorylation level of tau at individual phosphorylation sites and the level of VLDLR were analyzed by Western blotting. The activity of glycogen synthase kinase 3β, a key component of insulin signal transduction pathway and a known tau kinase, in the hippocampus of rats was determined by using [γ-~(32)P]-ATP and the specific peptide substrate. RESULTS: No significant difference of total tau level in hippocampus between T2DM group and T2DM mediated VLDLR gene group was observed. Tau protein in T2DM group was found to be more hyperphosphorylated at several AD-related phosphorylation sites(Ser214, Thr217, Ser396, Ser422 and Ser199/202)than that in CTL, while the immunoreaction at tau-1 site is weaker than that in CTL. VLDLR gene therapy reduced hyperphosphorylation sites of Thr217, Ser396, Ser422 and Ser199/202 of tau to almost the control level, but did not change the phosphorylation of Ser214 or Ser422 on tau. The expression of Ser214 was also observed by immunohistochemical assay. The phosphorylated tau modestly increased in hippocampus in T2DM group compared to CTL, but VLDLR gene treatment did not change the phosphorylation level. The phosphorylation of GSK-3β was decreased dramatically in the hippocampus in T2DM rats, and this phosphorylation was significantly increased after VLDLR gene treatment. CONCLUSION: These findings suggest that Raav mediated VLDLR gene treatment partially reverses tau hyperphosphorylation at several sites in T2DM rat hippocampus, which may mediate by inhibition of GSK-3β activity.

OBJECTIVETo review the clinical features of acute toxicity of aromatic amino and nitro compounds.
METHODSA total of 110 papers reporting 1240 cases of acute toxicity induced by aromatic amino and nitro compounds from 1979 to 2013 were collected from CNKI, VIP, and Wanfang database, and were analyzed in this study.
RESULTSOf all included cases, 939 were caused by occupational exposure, and 301 were caused by exposure in daily life. A total of 1044 cases were male, and 196 were female. Age ranged from 9 days to 75 years. There were 13 cases of contact reaction. The numbers of mild, moderate, and severe toxicities were 358, 348, and 139, respectively, and the other 382 cases were not graded for severity. The average incubation period was 4.50±5.71 h (M = 3 h). The average incubation period of aniline toxicity was significantly shorter than that of nitrobenzene toxicity. Methemoglobinemia was found in 1146 cases, while cases of poisonings with 5-nitro-o-toluidine, 2-methyl-4-nitroaniline, and 3-chloro-2-methyl aniline were not found to have methemoglobinemia. The detection rates of MHb and HzB were 83.73% (674/805) and 40.19% (129/321), respectively. Sixty-two (19.31%) out of 321 cases were complicated by intravascular hemolysis, 270 (30.93%) out of 873 cases suffered hepatic impairment, 50 (12.25%) out of 408 cases were accompanied by renal damage. Consciousness disorders were found in 66 cases, and chemical cystitis was found in 36 cases. Oral poisoning could immediately induce severe symptoms including cyanosis, unconsciousness, and hemolysis. In prognosis analysis, it was found that the cure rate was 98.71% (1224/1240), and 14 cases of death were caused by multiple organ dysfunction syndrome, renal failure, uncontrolled hemorrhagic shock, myocardial infarction, and sudden death. Two cases were left with neurological sequelae.
CONCLUSIONThe clinical manifestations of poisoning with aromatic amino and nitro compounds are methemoglobinemia, intravascular hemolysis, liver damage, and renal damage. Treatment with specific medicine methylene blue can produce ideal clinical prognosis, but severe poisoning may cause death from multiple organ failure.
