The adhesion molecules expressed by brain microvascular endothelial cell maintain the structure and function of brain, ensure the continuity of endothelium cell and penetrate blood-brain barrier in physiology. They also intervene inflammation cells that remove or orientate regular or inflammation organism in pathology. The adhesion molecules of Immunoglobulin supperfamily and Selectin family are expressed by brain microvascular endothelial cell and have affinity with the ischemic brain damage. The advance in research on relationship between the expression of adhesion molecules by brain microvascular endothelial cell and ischemic brain damage is reviewed in this article.

Objective To discuss the influence of blood exchange transfusions on hemato- microenvironment of neonates with hyperbilirubinemian.Methods Blood exchange transfusion was performed in 35 neonates.Mean transfusion volume was (136.9±27.4) ml/kg.The speed of blood exchange transfusion was 92 ml/(kg·h).Blood bilirubin,blood electrolyte,blood routine and blood sugar levels were measured before,during and after the transfusion.Results Serum total bilirubin (TB) decreased by 53.78% after blood exchange,but there was no change in Na~+,Cl~-,and blood sugar (P＞0.05),and K~+ was remarkably decreased from (4.45±2.40)mmol/L to (3.87±0.52)mmol/L (t=21.979,P＜0.05).TB,Hb,PLT,WBC,Ca~(2+) were decreased[TB from(511.52±80.21) μmol/L to (236.41±66.54) μmol/L;Hb from (145.20±11.70) g/L to (128.66±2.54) g/L;PLT from (207.84±70.67)×10~9/L to (134.86±48.61)×10~9/L;WBC from (16.90±10.56)×10~9/L to (8.94±7.44)×10~9/L,and Ca~(2+) from (1.26±0.32) mmol/L to (0.99±0.22) mmol/L,P＜0.05 or ＜0.01].Conclusions Blood exchange transfusion can not influence Na~+,Cl~-,and blood sugar,but has remarkable effect on total bilirubin,Ca~(2+),Hb,K~+,PLT,and WBC.

Objective To study the personality characteristics of the stagnation of liver-qi syndrome cases with Minnesota Multiphasic Personality Inventory (MMPI).Methods 20 liver-qi stagnation syndrome cases and 20 normal persons whose paired by sex and age were tested by MMPI. The scores of 13 clinical scales and the section plane of MMPI were acquired and analyzed. Results There was a significant difference in 9 clinical scales (F, Pa, D, Pt, Si, Sc, Hs, Hy, Pd) between the liver-qi stagnation syndrome cases and normal persons ( P<0.05～0.001). The scores of Hs, D, Hy, Pd in the liver-qi stagnation syndrome group were higher than the Chinese normal model. The MMPI section plane of liver-qi stagnation group presented the type of 3/1. Conclusion The patients with liver-qi stagnation have some special personality characteristics such as depression, anxiety, loneliness, indifferent and attention.

BACKGROUND:After entering the aging society, improving the balance function to prevent fals and reduce incidence of fractures in the elderly has received widespread attentions in al aspects. OBJECTIVE: To design a training program for the elderly, involving static stretching and strength exercise of lower limb, in order to study the combined effect on the balance function of the elderly. METHODS: Static stretching and strength training of the lower limbs were carried out in 28 elderly persons who met the inclusion criteria for 3 months, three times a week, once for 60 minutes. Before and after exercise training, the static balance ability with foot standing, eyes open and eyes closed was evaluated using the PRO-KIN balance instrument; the dynamic balance ability and lower limb strength were evaluated using treadmil test with eyes closed and chair-stand test. Evaluation results before and after exercise were compared and anayzed. RESULTS AND CONCLUSION:In the eyes open state, the average X-axis coordinate and exercise-induced elipse area at the center of pressure were significant different before and after exercise (P < 0.01); the mean velocities at the left and right direction were of significant difference before and after exercise (P < 0.05); the results of treadmil test with eyes closed and chair-stand test also presented very significant differences before and after exercise (P < 0.01). Static stretching combined with lower limb strength exercise can effectively improve the balance function and lower limb strength of the elderly, which can be used as an effective exercise way to prevent the fals in the elderly.

The active behavior of migraine-model-mouse was detected with tail suspension test and the analytical system of animal behavior-spontaneous movement.ResultsTL-Ⅰ prescription could prolong the quiescent time of migraine-model-mouse and shorten the active journey and time in the autonomic active box of migraine-model-mouse.ConclusionTL-Ⅰ prescription has sedative effect.

ObjectiveTo investigate the analgesic effect of TL-Ⅰ prescription.MethodsHealth ICR mouses were randomly divided into 6 groups: negative control group, positive control group, Tongtian group, large doses group,middle doses group and small doses group. The pain threshold of mouses were detected with hot plate and acetic acid writhing.ResultsTL-Ⅰ prescription can raise the threshold of pain induced by hot plate and reduce the numbers of writhing induced by acetic acid in mice, which was more significant in large doses group. ConclusionTL-Ⅰ prescription can be an effective analgesic.

R2) of the two models were 0.801,0.872 respectively. The fitting efficacy of the ARIMA-GRNN combination model was better than the single ARIMA, which had practical value in the research on time series data such as the incidence of scarlet fever.

Objective To improve the understanding of pulmonary mucormycosis by analyzing the clinical manifestations,imaging features,diagnosis,treatment and prognosis of this disease.Methods The clinical data of eight patients diagnosed as pulmonary mucormycosis by histopathologic examination were retrospectively analyzed.Results Eight patients included six males and two females with age from 36 days to 66 years.Underlying conditions covered diabetes (n =4),renal transplantation (n =3),premature (n =1) and long-term corticosteroid treatment in two cases.Imaging manifestations revealed multiple irregular lumps or nodules in three cases,multiple cavities with thick wall in three cases,diffuse lung infiltrate in one case and lung opacities in one case.The diagnoses of seven patients were confirmed by percutaneous needle lung biopsy and the remaining one was diagnosed with fiberoptic bronchoscopy biopsy.Surgery combined with amphotericin B liposome(60 mg/d for three weeks)was applied to one patient who was cured with no recurrence after a 22 month follow-up.Three cases were given amphotericin B liposome (a newborn with 7mg/d for 62 days,the other two 60 mg/d for 31 days and 70 mg/d for 71 days respectively).All had achieved marked response with follow up from 8 to 29 months,but one patient relapsed and died of recurrent lung mucormycosis.The other three patients were treated with itraconazole 400-200 mg/d from 21 days to 1 year with duration of follow up from 1 month to 20 months.One patient was not evaluable due to missing.Two patients relapsed and one died.Conclusion Pulmonary mucormycosis is difficult to diagnose and treat with a high mortality.Percutaneous tranthoracic lung biopsy is a useful diagnostic method.Amphotericin B liposome or itraconazole may be active against mucus.Early control of causes is essential to improve the prognosis and reduce the recurrence in patients with pulmonary mucormycosis.

Objective To evaluate the effects of different concentrations of sevoflurane anesthesia on longterm learning and memory abilities in neonatal rats.Methods Twenty-seven neonatal Sprague-Dawley rats of both sexes,aged 7 days,weighing 12-20 g,were randomly assigned into 3 groups (n =9 each):control group (C group),2％ sevoflurane group (S1 group) and 3％ sevoflurane group (S2 group).Groups C,S1 and S2 inhaled air,2 ％ sevoflurane and 3 ％ sevofluran for 4 h,respectively.The neonatal rats were reared to 35 days old and underwent open field test,to 36 days old and underwent Morris water maze test,and to 42 days old and underwent continuous multiple-trail inhibition avoidance training.Results Open field test:There was no significant difference in the movement time,movement speed and the time the animals spent in the central square among the 3 groups (P ＞ 0.05).Morris water maze test:Compared with C group,the looking for platform latency on 2nd-5th days in S2 group and on 2nd-3rd days in S1 group was significantly prolonged,and the percentage of time of staying at the platform quadrant was decreased in S1 and S2 groups (P ＜ 0.05 or 0.01).The looking for platform latency on 3rd4th days in S2 group was significantly longer than that in group S1 (P ＜ 0.05).Continuous multiple-trail inhibition avoidance training:The latency detected at 24 h after training was significantly shorter in S1 and S2 groups than in group C (P ＜ 0.05),and in group S2 than in S1 group (P ＜ 0.05).Conclusion Sevoflurane anesthesia decreases the long-term learning and memory function in neonatal rats in a concentration-dependent manner.
