Objective To clarify the role of hypothalamic IL-6 in gastric mucosal blood flow, gastric juice pH value and gastric mucosal injury. Method Model of gastric stress ulcer was established by fluid percussion to make craniocerebral trauma. Twenty male SD rats fed for one week in the experiment room were randomly(random number) divided into control group, one hour group, six hours group and 12 hours group after injury. The levels and distribution of IL-6 in hypothalamus were detected by using immunohistochemistry and Western blot. Simultaneously, gastric pH value, gastric mucosal blood flow and gastric mucosal injury index of rats in each group were measured, and the histology of gastric mucosa was observed. Results IL-6 immunoreactive cells were widely distributed in neuronal cells of hypothalamus of the stressed rats especially in the para-ventricular nucleus (PVN).One hour after injury, the pH value rapidly declined, and the lowest point appeared 6 hours later. One hour after injury, the injury of gastric mucosa was found, and the injury became worse and worse as time got longer and longer. The ulcer index (UI) was increased. One hour after injury, there was a brief increase in blood flow to the peak in gastric mucosa, and then the blood flow declined until 6 hours elapsed and got stable. The experiment prompted the gastric stress ulcer appeared. Conclusions In the SD rats with gastric stress ulcer induced by craniocerebral injury incurred by hydraulic percussion, the hypothalamic IL-6 may activate neuronendocrine metabolism mediated through the activation of PVN, inducing gastric mucosal injury.

Objective To compare the impact on the results tested with arterial blood gas analysis and peripheral blood with glucose meter for critical patients in ICU in different temperature states. Methods The samples of venous biochemical test, blood arterial blood gas analysis and peripheral blood of 196 cases of critical patients in ICU were collected synchronously, and measure the D-value, correlation and bias adjustment factor of glucose blood tested with a synchronous fasting blood glucose test and venous/biochemical analyzer in different temperature states and different blood glucose groups, and the results of blood glucose test were analyzed. Results In normal temperature state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 3.31%(5/151), while the pairwise comparison showed there was both statistical signifcance between hypoglycemia group and target group (χ2=38.469), hyperglycemia group and target group (χ2=15.504) when choosing a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). In high temperatures state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 0. There was both statistical significance between hypoglycemia group and target group (χ2=18.187), hypoglycemia group and hyperglycemia group (χ2=12.857) when choose a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). Conclusions In high temperatures state, a synchronous fasting blood glucose test can not reflect the true value of blood glucose for critical patients.

Human bocavirus (HBoV) 1-4 have been detected both in respiratory and stool samples since the first HBoV was discovered in 2005. HBoV-1 is mostly associated with respiratory infection, while HBoV 2-4 are usually associated with intestinal tract infection. A variety of signs and symptoms have been described in patients with HBoV infection, including cough, wheezing, pneumonia, and diarrhea, but the research on pathogenic mechanism of HBoV is limited because HBoV cannot be cultured in vitro due to the lack of appropriate host cells. Three-dimensional epithelial cell culture, reverse genetics, and viral metagenomics are identified as novel tools that may promote the research on pathogenic mechanism of HBoV and the discovery of new viruses. This review summaries currently available diagnostic approaches such as electron microscopy, cell culture, PCR, and immunoassay in order to provide a method reference for indepth research on HBoV.
