Objective:To study the effect of growth hormone(GH) on acute lung injury induced by endotoximia and its’ mechanism.Methods:After introduction of acute lung injury(ALI) by endotoximia,one hundred and tweleve male Sprague-Dawley rats were randomly divided into ALI group and GH group. Western blot,immunofluorescence staining and semi-quantitive reverse transcription polymerase chain reaction(RT-PCR) were used to determine the expression and activation of nuclear factor kappa B(NF-?B), the levels of CC16 protein and the expression levels of CC16 mRNA in ALI rats’ lung.Results:Both the expression levels of CC16 mRNA and the contents of CC16 protein in ALI rats’ lungs began to decrease significantly 0.5 h post-injury,reached nadir at 6 h post-injury,and then began to recover.Both the expression levels of CC16 mRNA and the contents of CC16 protein in GH group were significantly lower than those in ALI group at different time intervals post-injury.The dynamic changes of the expression and activation of NF-?B were contrast to those of CC16 protein levels.Correlation analysis indicated that CC16 correlates significantly with the extent of lung injury and the expression and activation of NF-?B.Conclusion:Down-regulation of CC16 expression plays a critical role in the pathogenesis of acute lung injury induced by endotoximia.The application of GH can deteriorate the lung injury induced by endotoximia through down-regulating the expression of CC16.

Objective To retrospectively analyze diagnosis and treatment of chronic pancreatitis. Methods One thousand and seven hundreds patients with confirmed chronic pancreatitis in 21 hospitals were retrospectively studied,including their associated etiological factors,diagnostic and therapeutic methods.Results Among these patients,601 were alcoholic,576 were biliary diseases origin,which ac- counted for 35.4% and 33.9%,respectively.The most common symptom of chronic pancreatitis was abdominal pain.Some of patients accompanied by steatorrhoea and decreased body weight.Part of pa tients(239 cases)were diagnosed by histopathologic examination.Others were diagnosed by imaging techniques.Alleviation of symptoms was achieved with conservative management.Conclusions Alcohol consumption was the most common predisposing factor for chronic pancreatitis.Imaging techniques play the most important role in diagnosis of the disease,and non-operation managements were the main meth- ods for treatment of chronic pancreatitis.
