Objective To explore the role of human urinary trypsin inhibitor(UTI) in severe acute pancreatitis (SAP). Methods UTI was highly purified from the urine of patients with acute pancreatitis by column chromatography. SAP models were established by injection of 5% sodium taurocholate(NaTc) at dose of 0.1 ml/100 g weight under pancreatic capsule. The interleukin 6(IL 6) level in each group was measured by ELISA. Results ① The highly purified UTI with high yield was harvested. ② SAP models were established successfully. ③ The level of IL 6 in SAP group was significantly higher than that in NC, but in UTI group, the increase was not obvious. Conclusion The alleviating effect of UTI on the pathological damage degree in rats with SAP is related to the inhibitive effect of UTI on the expression of IL 6.

Objective To explore the clinical value of real time contrast-enhanced ultrasound in diagnosis of liver localized fatty deletion and fatty infiltration which couldn't be confirmed by conventional ultrasonography. Methods Contrast-enhanced ultrasound was performed on 94 patients with liver localized diseases confirmed by baseline sonography, among them 34 patients with liver localized fatty deletion and fatty infiltration were enrolled. Results Contrast-enhanced ultrasonography didn't show apparent occupancy nidus in 34 patients. Enhancement mode of lesions was the same as liver parenchyma, which was distinctly different from liver occupancy diseases. Conclusion Real time contrast-enhanced ultrasound can display typical signs of liver localized fatty deletion and fatty infiltration and has significant value in diagnosis and differentiating diagnosis of them.

Objective To evaluate the appl ication of CT perfusion in intra-axia l disease. Methods By applying a nuclear medicine data processi ng technique to the time-density data obtained from dynamic CT, cerebral tissue perfusion was p e rformed in 8 cases, 4 with normal findings, 2 with ischemic cerebrovascular dise ase, and 2 with gliomas. Cerebral blood perfusion maps was created and analyzed, absolute regional cerebral blood volume, regional cerebral blood flow, and mean transit time were determined and analyzed as well. Results Wit h regard to var ious degrees of perfusion impairment within the ischemic territory, thus giving rise to a very heterogenous appearance. As a rule, the center of a lesion usuall y representing the core of ischemia showed marked reduction of blood flow. At th e outer margin of a tumor area, the reduction of CBF and CBV was often less pron ounced, indicating some residual flow via collaterals, as was confirmed by the b olus delay on the time to peak time. Conclusion In the near fut ure, functional imaging techniques should have a major impact on therapeutic decision-making i n acute stroke patients, perfusion CT may be recommended even now for emergency applications in daily patient care due to its practicability.

For uncontrolled hemorrhagic shock the traditional method and target of resuscitation may be harmful. The existing data supported a strategy of less aggressive interventions to those shock with uncontrolled hemorrhage until a decisive surgery begin. The choice of liquor for resuscitation remains in controversy. A combined application of crystalloid and colloid liquor seems to be reasonable and may be accepted by most physicians. It should be noted that the new resuscitation strategy may not be suitable to some kinds of trauma, such as traumatic brain injury, and its long-term effects on to the prognosis should be further evaluated.

Objective To explore the clinical curative effect of recombinant human endostatin injection combined with chemotherapy in the treatment of patients with advanced gastric cancer and malignant ascites,and its influence on the quality of life.Methods 62 patients with advanced gastric cancer from July 2012 to July 2015,were randomly divided into observation group (31 cases)and control group (31 cases).The control group was treated with FOLFOX6 chemotherapy,the observation group was given recombinant human endostatin injection on the basis of the treatment of the control group.The two groups were treated for 3 weeks.The curative effect,QOL score,Karnofsky score,the change of serum CEA and CA19 -9 levels and drug adverse reaction incidence before and after treatment were compared in the two groups.Results The RR of the observation group was higher than that of the control group (54.84 vs 29.03%,χ2 =4.239 3,P <0.05).The QOL score and Karnofsky score in the two groups were increased after treatment (P <0.05).The QOL score and Karnofsky score after treatment in the observation group were higher than the control group(t =6.512 7,5.669 0,all P <0.05).The serum CEA and CA19 -9 levels of the two groups decreased significantly after treatment (P <0.05).The serum CEA and CA19 -9 levels of the observation group were lower than the control group after treatment (t =5.276 0,6.310 8,all P <0.05).The leukopenia,thrombocytopenia, peripheral neurotoxicity,decreased hemoglobin,diarrhea,nausea and vomiting adverse reaction rate of the two groups had no significant differences (P >0.05).Conclusion The clinical efficacy of recombinant human endostatin injec-tion combined with malignant ascites in the treatment of patients with advanced gastric carcinoma is significant,and can significantly improve the quality of life of patients,has the important research value.
