Progesteron could significantly inhibit the contracted effect of strips of tracheal and lung smooth muscles isolated from guinea pigs, which induced by Ach His and 5- HT. It also inhibited the contractility of phase I caused by intracellular calciumefflux in the course of 5 -HT stimulating tracheal smooth muscles and the Schultz - Dale responsiveness of sensilized of tracheal smooth muscles guinea pigs.

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 study parenting style of difficultly educated children and the state of their mental health.Methods:Randomly select 120 difficultly educated children from a Training Camp in Changsha and used SCL-90 and EMBU to rate their parenting style and mental health.Results:The mental health condition of difficultly educated children was significantly worse than the norms,but the normal middle school students parental warmth was higher than the difficutly educated students.Difficultly educated children scored significantly higher in father's firm control,punishment,over interference,rejection and denial and maternal rejection and denial,firm control and punishment,but significantly lower in parental warmth.Conclusion:Difficultly educated children had got more mental problems,and their parents treat them with more negative parenting style and less positive parenting style.

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 clarify malaria infection and the incidence in first Chinese medical team of United Nation peacekeeping mission in Democratic Republic of Congo and evaluate the effect of prevention measures so that provide reference for studying on malaria prevention and the precautionary measures for the follow-up personnel in Africa. Methods 43 cases (male 30, female 13) were observed between Apr. and Dec. 2003 when they were deployed in D.R.of Congo. Eliminating mosquito was used to decrease the density, including the usage of driving mosquito machine, killing mosquito lamp and chlorine cyanogens chrysanthemum ester, ”Prevent malaria-3”and COTECXIN as the precautionary medicines. Plasmodiums in blood were checked periodically. The cases with positive result of blood test and without clinical symptom was considered as infection, otherwise as disease with symptom appeared. Results The density of mosquito in house decreased. 3 cases (male 2, female 1) suffering from malaria, the incidence was 6.98%. Plasmodium was found in 39 individuals (male 26, female 13), the infection rate was 90.70%. The incidence was the lowest compared with contingents from other countries. Conclusion It was effective that these measures taken by reducing mosquito density and ”Prevent malaria-3”and COTECXIN usage in Chinese medical team during peacekeeping mission .

Objective To observe physiological and ultrastructure changes in rabbits breathing various contents of oxygen during exposure to high altitude. Methods Twenty healthy rabbits were randomly divided into air-breathing group, 63% oxygenbreathing group, 83% oxygenbreathing group and pure oxygen breathing group. All rabbits were exposed to an atmosphere corresponding to an altitude of 11 000m in hypobaric chamber for 30min. The amount of air bubble in the heart and ECG of rabbits were recorded, the ultrastructural changes in the heart and brain were examined, and the expression of kidney erythopoietin (EPO) was also observed. Results The amount of air bubbles in the air breathing group was increased remarkably, and most of the rabbits developed arrhythmia. With the increase of oxygen concentration, the changes in ultrastructure were alleviated and the expression of kidney EPO decreased. Conclusion Oxygenconcentration above 80% could provide obvious protection for rabbits during their exposure to high altitude.
