Objective To investigate the effect and the mechanism of parecoxib sodium pretreatment on permeability of blood-brain barrier in a rat model of focal cerebral ischemia-reperfusion injury.Methods Sixty male SD rats weighing 300g were randomly divided into 5 groups (n=12 each):sham operation group (group S);focal cerebral I/R group (group I/R);parecoxib sodium 5 mg/kg pretreatment group (group L);parecoxib sodium7.5mg/kg pretreatment group (group M);parecoxib sodium 10 mg/kg pretreatment group (group H) Middle cerebral artery occlusion models were made by reforming Longa suture method in SD rats.Thirty minutes before ischemia,rats in group L,M and H were injected with 5 mg/kg、7.5 mg/kg and 10 mg/kg parecoxib sodium through the internal jugular vein.Group S and group I/R received equal volume of normal saline.ELISA technique was used to determine the content of S100 β,TNF-α,IL-1 β in Plasma.The changes of cerebral water content and the Evans Blue exudation from brain capillaries were observed.Results Pretreated with parecoxib sodium (5mg/kg、7.5 mg/kg and 10 mg/kg),the content of S100 β,TNF-α,II-1 β in plasma were reduced.The cerebral water content and the EB in brain were reduced.Pretreated with parecoxib sodium 10 mg/kg,Longa scores were reduced.Conclusion Pretreatment with Parecoxib can protect blood-brain barrier against focal cerebral I/R injury by inhibition of the inflammatory reaetion.

ObjectiveTo study the neuron protection mechanism of Uncariae Ramulus Cum Uncis extract for the MPTP-induced PD mice.MethodsC57BL/6 mice were randomly divided into control group, model group, Uncariae Ramulus Cum Uncis extract group and madopar group, and injected with MPTP in abdominal cavity. Behavior test was used to detect grabbing capacity and body movement coordination capacity: three biochemical indexes (SOD, MDA, GSH-Px) were detected by biochemical process and the activity of two immune enzyme-linked indexes (IL-1β, IL-6) were detected by enzymelinked immunosorbent assay.ResultsCompared with the control group, the autonomic activity numbers of mice increased and climbing pole time decreased in the model group (P<0.05), enzymatic activity of SOD and GSH-Px decreased significantly and the contents of MDA, IL-1β and IL-6 increased obviously (P<0.01). Compared with model group, the autonomic activity numbers of mice increased and climbing pole time decreased in the Uncariae Ramulus Cum Uncis extract group and madopar group (P<0.05). Enzymatic activity of SOD and GSH-Px increased and the contents of MDA and IL-1β and IL-6 decreased (P<0.05,P<0.01).ConclusionUncariae Ramulus Cum Uncis extract can reduce neuronic apoptosis PD mice, whose therapeutic action may be realized through eliminating oxygen free radicals, improving oxidation resistance and reducing inflammatory reactions.

Objective To optimize the prescription ofBaichanting Tablets by the central composite design-response surface methodology.Methods The doses of MCC, cCMC-Na, SiO2, and magnesium stearate were set as investigation factors; disintegration time and moisture rate were set as indexes. Linear equation quadratic polynomial described mathematic relationship of disintegration time and moisture rate with other four influence factors. Response surface was described according to the optimal mathematic models; the optimal prescription was chosen; predictive analysis was conducted.ResultsThe relationship of disintegration time and moisture rate with other four influence factors could not be described by linear equation. When quadratic polynomial matching was used, correlation coefficients were 0.837 9 and 0.923 1, with relatively high reliability. Optimal prescription contained 30.6%MCC, 10%cCMC-Na, 0.30%SiO2, and 0.10% magnesium stearate. The theoretical value and predicted value deviations of the disintegration time limit and moisture absorption rate were within 5%.Conclusion The predictability of the established model is good. Application of central composite design-response surface methodology can precisely optimize the prescription ofBaichanting Tablets.

Objective To analysis the clinical outcome at discharge and its risk factors of extremely preterm infants.Method To retrospectively analysis the clinical outcome at discharge and it's risk factors of extremely preterm infants (less than 28 weeks gestation) admitted from September 2008 to August 2014 in our Hospital.Result A total of 179 cases were enrolled.Survival rate was 59.2％ (106/179).Unfavorable outcome rate was 74.3％ (133/179),among them 73 cases died.The top five causes of death were severe bronchopulmonary dysplasia (BPD) (28 cases),Ⅲ ～ Ⅳ o intraventricular hemorrhage (IVH) (19 cases),sepsis (16 cases) and necrotizing enterocolitis (NEC) (6 cases).Among the 60 survivals with unfavorable outcomes,35 cases had either severe neurologic or ophthalmological sequela,and 25 cases had severe pulmonary sequela.Univariate analysis showed that,comparing with improved group,unfavorable outcome group had higher rates of not receiving prenatal steroids,placental abruption,male,small for gestation age,resuscitation with chest compression,admission age older than 72 hour,severe respiratory distress syndrome (RDS),without pulmonary surfactant (PS) usage,mechanical ventilation beyond 2 weeks and sepsis (P ＜ 0.05).Logistic regression analysis showed that those without prenatal steroids (OR =9.402,P =0.002),small for gestational age (OR =8.271,P =0.018),resuscitation with chest compression (OR =6.325,P =0.023),admission age older than 72 hour (OR =4.174,P =0.028) were independent risk factors for unfavorable outcome of extremely premature at discharge.Conclusion Extremely preterm infants have a higher rate of unfavorable outcome at discharge.Avoid small for gestational age,transfer properly and in time both in utero and after birth,and conduct prenatal steroids could improve their clinical outcome at discharge.

Objective To analyze the clinical features,therapeutic effect and prognosis in patients with bone pain induced by malignant bone me?tastasis as well as the rationality of analgesic application,so as to improve the level of diagnosis and treatment for metastatic bone pain. Methods Totally 123 patients with pain due to malignant bone metastasis received antitumor therapy and analgesic therapy based on standardized three?step guidelines. Their clinical characteristics were retrospectively analyzed. Results The total pain relief rate was 85.4%and the pain was significantly relieved(P<0.05). The DUI value of each narcotic agent was close to 1 and the application of narcotic agents tended to be rational. The Kaplan?Meier survival analysis showed that patients with moderate pain had longer survival time than those with severe pain(P=0.015). The survival rate of patients with significant pain relief after treatment was higher than those unrelieved(P=0.021). The survival rate of patients without visceral me?tastasis was higher than those with visceral metastasis(P=0.000). The COX multivariate analysis indicated that the pain intensity and visceral me?tastasis were independent risk factors influencing patient prognosis. Conclusion Standard treatment can improve symptoms in most patients with bone metastasis and prolong survival time. Opioids have satisfactory analgesic effect for moderate to severe pain and the adverse reactions can be tol?erated.
