BACKGROUND: At present, more and more people pay attention to the protection of sub-hypothermia on cerebral ischemic tissue and the effect of sub-hypothermia treatment on inflammatory reaction after cerebral ischemia-reperfusion.OBJECTIVE: To investigate the effect of sub-hypothermia on inflammatory cytokine in cerebral ischemic area of rats and protection on cerebral reperfusion injury.DESIGN: Randomized controlled study on the basis of animals.SETTLNG: People's Hospital of Hubei Province.MATERIALS: The experiment was completed at Laboratory Center of Renmin Hospital of Wuhan University from October 2004 to February 2005. Totally 50 healthy SD rats of clean grade were selected in this study.METHODS: Ten SD rats were divided randomly into normal group and sham operation group with 5 in each group. Other 40 rats were divided randomly into normal temperature cerebral ischemia group and sub-hypothermia cerebral ischemia group with 20 in each group. Rats except 5 in normal group were used to establish reversible ligation model of left middle cerebral artery (MCA) with Longa ligation method. Rats in sham operation group and normal temperature group were put in 20 ℃ room, and anus temperature was maintained at 37 ℃; rats in sub-hypothermia group were put in 4 ℃ room and anus temperature was maintained at (33.0±1.0) ℃.Rats in sub-hypothermia group were treated with sub-hypothermia on whole body, after ischemia, temperature was changed normally, and reperfusion was started 3 hours after cerebral ischemia. All modeling rats were scored with neurological defect: 0 point: none of neurological defect; 1 point: unable to unfold bilateral anterior claws; 2 points: cycling to hemiplegia side during walking; 3 points: falling to hemiplegia side; 4 points: unable to self-walk and with unconsciousness.MAIN OUTCOME MEASURES: Expression of tumor necrosis factor (TNF) andinterleukin-1 in cerebral tissue of ischemic rats, percentage of volume of cerebral infarction,and neurological functional scores.RESULTS: Fifteen rats were excluded because of intracranial hemorrhage,anesthetic accident and unqualified neurological functional scores. Other 15 rats with successful modeling were supplied randomly, and totally 50rats entered the final analysis. ① Number of TNF positive cell in immunohistochemical staining: There were no significant differences between normal group and sham operation group [(3.54±1.24, 3.71±1.50) /sight]; but numbers in sub-hypothermia group were lower than those in normal temperature group [(31.94±7.23, 69.20±9.43)/sight, F=179.16, P ＜ 0.001]. ②Numbers of interleukin-1 positive cells in immunohistochemical staining:There were not significant differences between normal group and sham operation group [(3.20±1.34, 3.89±2.08) /sight]; but numbers in sub-hypothermia group were lower than those in normal temperature group [(28.95±4.97, 55.79±7.93)/sight, F=174.95, P ＜ 0.001]. ③ Volume percentage of infarct focus: Percentage in sub-hypothermia group was lower than that in normal temperature group [(21.06±2.42)%, 30.32±2.71], F =374.87, P ＜ 0.001]. ④ Neurological functional scores: Percentage in subhypothermia group was lower than that in normal temperature group [(1.35±0.27)%, (2.04±0.34)%, F=117.17, P ＜ 0.001].CONCLUSION: ① Volume of cerebral infarction focus is lower in subhypothermia group than that in normal temperature group, this suggests that sub-hypothermia can protect ischemic neurons. ② Positive expressions of TNF and interleukin-1 are observed rarely in normal group and sham operation group, but more expression of positive cells are observed in cerebral ischemic area with 24-hour reperfusion after ischemia, this suggests that cerebral ischemia starts expression of inflammatory cytokine, evoke inflammatory cascade reaction, deteriorate cerebral ischemia-reperfusion injury. Therefore, inhibition of inflammatory cascade reaction is one of important mechanisms of protecting brain.

Objective To evaluate the effects of treatment with different fluids on systemic inflammatory response in newborn rabbits with septic shock. Methods One hundred New Zealand white rabbits (3-5 days, 45-70 kg) were randomly divided into 5 groups (n = 20 each):group Ⅰ sham operation (group S); group Ⅱ sepsis (group CLP); group Ⅲ lactated Ringer's solution (group R); group Ⅳ 6% HES (group HES) and group V (group R+ HES). The animals were anesthetized with intraperitoneal ketamine and midazolam. Sepsis was induced by cecal ligation and puncture (CLP). The animals in group R and HES received lactated Ringer's solution and 6% hydroxyethyl starch (HES) 30 ml/kg infused iv over 1 h respectively immediately after CLP,while group R+ HES received Ringer's solution 20 ml/kg and 6% HES 10 ml/kg. Nio fluid was infused in groups S and CLP. Carotid artery and jugular vein were cannulated for MAP monitoring, blood sampling and drug and fluid administration. MAP was recorded immediately (T1) and at 0.5, 1, 2, 4, 8 h (T2-6) after CLP. Arterial blood samples were collected at T6 for determination of plasma IL-6 and IL-10 concentrations. Results Compared with those at T1, MAP decreased significantly after CLP at T4-6 in group CLP and at T5.6 in group R but hypotension did not develop after CLP in group HES and R + HES. Plasma IL-6 concentration was significantly higher in group CLP and R than in group S. There was no significant difference in plasma IL-6 concentration between group S and group HES and R + HES. Plasma IL-10 concentration was significantly lower in group CLP and higher in group HES than in group S. There was no significant difference in plasma IL-10 concentration between group S and group R and R + HES. Plasma IL-6 concentration was significantly lower, while plasma IL-10 concentration was significantly higher in group R + HES and HES,and plasma IL-10 concentration was significantly higher in group R or6% HES infused iv alone in maintaining the balance between pro-and anti-inflammatory cytolines in newborn rabbits with septic shock.

Objective To explore the characteristics of uhrasonography of hepatobiliary cystadenoma. Methods The ultrasonographic characteristics of 5 cases with hepatobiliary cystadenoma were retrospectively analysed, and compared with the operation and pathology. Results The ultrasonography of 5 cases was multilocular cystic mass,which seems to be,but not indeed communicating with the biliary tree,in which irregular septation was demonstrated in two-dimensional structure and also with perforator vessels along in color Doppler flow imagineg. And in some cases small papillary tuft and small loci of calcification was noted on the septation. Conclusions Muhilocular cystic mass,locating along the biliary tree, however not communicating with the the biliary tree, is an important diagnostic basis of biliary cystadenoma. And it should be distinguished with other cystic tumor in the liver.

ObjectiveTo investigate the effect of montelukast on the secretion of mucus protein in lipopolysaccharide (LPS) induced human bronchial epithelial cells.MethodsPrimary human bronchial epithelial cells were isolated and identiifed in vitro. LPS (1μg/mL) was used to induce cell inlfammatory response. Montelukast (50 μmol/L, 20μmol/L, 10μmol/L) was used as intervention. The concertration of mucin-5 subtype AC (MUC5AC) in cell supernatants was measured by ELISA. The expression levels of MUC5AC mRNA and protein were determined by RT-PCR and Western-blot. DCFH-DA lfuorescent probe was used to detect reactive oxygen species (ROS). To further elucidate the mechanism, NF-κB (p65)、IκBα、ERK1/2 phosphorylation be-fore and after montelukast intervention were determined by Western-blot.ResultsMontelukast decreases the expression levels of MUC5AC mRNA and protein in a dose-dependent manner in LPS induced human bronchial epithelial cells. Meanwhile, mon-teluskast suppresses ROS generation and NF-κB (p65)、IκBα、ERK1/2 phosphorylation.Conclusions In response to LPS in-duced inlfammation, montelukast decreases the expression level of MUC5AC in vitro, which may be related to NF-κB and ERK activation.

Objective To observe clinical effects of compound Muniziqi granules combined with vitamin A acid cream, and analyze its mechanism of action.Methods 76 cases of patients with chloasma treated in our hospital in March 2010 to February 2014 were selected.They were divided into two groups according to random number table method, 38 cases in each group.Observation group was given compound Muniziqi granules( three times per day,orally) combined with vitamin A acid cream(smear once respectively each morning and evening),control group was taken vitamin C 0.3 g and vitamin E 0.2 g ( three times per day, orally ) comined with vitamin A acid cream ( smear once respectively each morning and evening ) treatment.Observed clinical effects, scores of lesion area and color, detected serum estrogen level in both groups by radioimmunoassay.
