Objective To explore the blood drug concentration monitoring of sustained-release valproate(DK)in children with epilepsy,focusing on the selection of sampling time and evaluation of the results.Methods Two hundred and seventy-one children taking DK and 155 children taking sodium valproate syrup(VPA Syr)were involved and their serum were taken when achieved steady state to determine the valproic acid level using fluorescence polarization immunoassay.They were divided into 4 groups,which were DK taken once daily group(DK qd group,126 children),DK taken once daily at night and sampled on morning group(DK qn group,26 children),DK taken every 12 h group(DK q12 h group,119 children),VPA Syr q12 h group(155 children).Determine the proportion of the blood drug concentration of each group below,ithin and above the therapeutic range for valproate(50-100 mg/L)were determined.The data were analyzed by t test.Results The Cmin of DK qd group were(73.09?19.91)mg/L,significantly lower from the serum concentration of DK qn and sampled on morning group [(94.94?25.44)mg/L](P0.05).Conclusions DK qn should sampled at night before the night dose.The Cmin of DK q12 h was higher according to the therapeutic range,it's favorable range still needs clinical practice.

Objective To observe the therapeutic effects of fenestration in the treatment of dentigerous cyst in mixed dentition stage. Methods From 2004 to 2007, 8 cases of dentigerous cyst in mixed dentition stage were treated, among whom 3 were boys and 5 were girls with ages between 7 and 12 years old. The dentigerous cysts of 2 cases were in superior maxillary bone and the other 6 cases were in inferior maxillary bone. Each of 5 cases had one tooth in dentigerous cyst cavity, and each of the other 3 had 3 teeth in dentigerous cyst cavity. All patients received fenestration under local anesthesia. The patients were followed up for 18 months after fenestration, and the soft tissue healing, facial malformation, permanent teeth eruption and bone tissue healing were observed. Results It was found during follow up that cyst cavity disappeared in all the patients and all had normal facial morphology with no maxillary bone malformation. In five cases, permanent teeth erupted totally and dental occlusion kept normal. In one case, 2/3 of permanent teeth erupted and dental occlusion kept almost normal. While in the other two cases, permanent teeth were to erupt. It was revealed by X ray examinations that the shadow of maxillary bone density decrease disappeared in all the patients. Conclusion Fenestration can keep the teeth and bone in the treatment of dentigerous cyst in the mixed dentition stage.

AIM The purpose is to study the anti-arrhythmic effects of extracts from cultured Cordyceps sinensis. METHODS Aconitine and barium chloride were used to induce experimental arrhythmia models in rats. RESULTS The results showed that PE was more potent than other ingredients. Pretreatment with PE by oral administration significantly antagonized arrhythmia induced by aconitine. PE significantly prolonged the onset of arrhythmia, decreased the duration and diminished the degree of severity. And in barium chloride-induced arrhythmia model, PE had some anti-arrhythmia effect,which could diminish the degree of severity effectively to some extent. CONCLUSION PE is an active component to antagonize arrhythmia induced by aconitine and barium chloride.

Stenotrophomonas maltophilia is among eight strain of broad resistance to antibacterial. It has been pay attention to global students, and is very difficulty in clinic treatment. Infection of Stenotrophomonas maltophilia is more familiar in ICU. Its test rate is 13.45%(62/461) in the study .The resistance character: IPM﹑CZO﹑CRO﹑AMP and MNO is highest(resistive rate 100%). ATM、GEN 、 KAN 、MEM 、CTX and PIP is much high(≧86.5%), LVX﹑GAT and FEP is high (=50%).Conclusion: Stenotrophomonas maltophilia should be monitored in the hospital. Used of antibacterial must be rational. Severe disinfection and isolation should been put in practice to the infected patients. CSL is very active antibacterial (active rate 90.6%) against Stenotrophomonas maltophilia in the study, and ought be selected headmost in treated its infection.

Objective To investigate the possible damaging effect of infrasound on ultrastructure and permeability of rats′ blood retinal barrier (BRB). Methods Twenty mature male rats, averagely divided into 5 groups according to the exposure duration, were exposed to infrasound at a 16 Hz frequency and 130 dB sound pressure level in a pressure chamber for 2 hours per day. After exposed for 0, 1 day, 7, 14, and 21 days respectively, ultrastructural changes of rats′ BRB were observed through injection of lanthanum (La) nitrate solution, which was used as a tracer to demonstrate the breakdown of the BRB. Results With prolonging the duration of infrasound exposure, BRB structure lesion, chondriosome tumefaction, endoplasmic reticulum expandedness, membrane disc damage, retinal pigment epithelial cells distortion and putrescence, karyotheca expandedness, and La leakage on each level of retina aggravated gradually. Conclusion Infrasound may cause the breakdown of BRB, and the lesions aggravated with prolonged infrasound exposure time.

Hoxa3-Pax1/Pax9-Eya1-Six1/4 regulatory pathway seems to be operating during forming the bilateral parathyroid/thymus common primordial in early embryonic development.The specification of the parathyroid domain in the parathyroid/thymus primordial is regulated through a Shh-Tbx1-Gcm2 pathway.Gcm2 also may play roles in later steps of parathyroid development,including CaSR and PTH gene expression.MafB and Gcm2 interact with each other and synergistically activate PTH transcription.Genetic basis and the etiology of some hypoparathyroid disorders in man are involved defects in transcription factors that include GCMB,GATA3,Tbxl,SOX3 and GNA11.This marker expression in thymus and parathyroid primordium includes HoxA3,Pax1,Eya1,and Six1;and expression of parathyroid cell-like cells includes Gcm2,CaSR,and PTH.These expressions may serve as markers of stem cell differentiation into parathyroid cell-like cells.

There is no radical cure for essential thrombocythemia currently. Professor SUN Xue-mei has extensive clinical experience in treating it by combined therapy of Chinese and Western medicine. In this paper, authors tried to summarize her experience from guiding ideology and therapeutic points. Authors insisted on the direction of integrative medicine on the basis of syndrome differentiation, paying attention to psychological counseling,and applied individual treatment in clinics.
