It had been found that there was the relationship between leukemia and thyroid function.Treatment of leukemia and hematopoietic stem cell transplantation affect thyroid function,induce thyroid disease syndrome and secondary thyroid lesion.Leukemia is relate to family autoimmune thyroid diseases.Thyroid hormone may affect the bone marrow hematopoietic function.Current studies reviewed the relationship between leukemia and thyroid function.

Hypertrophic cardiomyopathy is an autosomal-dominant disease.Disease-causing mutations have been found in genes encoding structural components of the thick and thin filament systems of cardiac myocyte;it has therefore been named as a disease of sarcomere.Many approaches have been used to characterize the pathogenesis of the desease.Transgenic animal models have been created to gain further insight into the pathogenesis of this disease.Most of these models has been made in mice;however,recently a transgenic rabbit model has been created.In addition,there are several natural-occurring forms of HCM in animals.The discovery of responsible genes and the elucidation of the molecular mechanisms of pathogenesis through the use of animal models promise improved and early diagnosis and the potential for mechanism-based therapeutics.

AIM: To establish the determination for camphor, menthol, synthetic borneol, and methyl salicylate in four kinds of TCM adhesive plasters by GC. METHODS: The internal standard method was employed. Naphthalene, the internal standard, was added to the sample before treatment. The sample solution was prepared by distillation with essential oil collector. The GC system consisted of glass column, 10% PEG 20M as the stationary phase, nitrogen as the carrier gas, column temperature at 130℃, and FID as the detector. RESULTS: Camphor, menthol, synthetic borneol(borneol and isoborneol), and methyl salicylate in 6 lots of samples and naphthalene have been separated well under the chromatographic condition. In the methodology study on Fengshi Zhitong Adhesive Plasters, the average recovery of camphor, menthol, synthetic borneol, and methyl salicylate were 95.54%( RSD =1.6%), 96.90%( RSD =2.2%), 97.30%( RSD =1.4%), and 96.48%( RSD =2.8%), respectively. CONCLUSION: The method is sensitive, accurate and reproducible, and can be used to control the quality of the four kinds of preparations.

Objective To investigate the effects,safety,controlling of controlled hypotension induced by remifentanil during endoscopic sinus surgery.Methods Forty patients with ASA grade Ⅰ～Ⅱ undergoing selective endoscopic sinus surgery,were randomly assigned into remifentanil group(A group)and nitroglycerin group(B group).After routine inducing,controlled hypotension was induced before the main procedure of surgery.A group was given remifentanil(1μg/kg)by intravenous injection,then remifentanil(0.3～0.8μg·kg~(-1)·min~(-1))was used in group A to keep mean arterial pressure between(MAP)60 and 80 mm Hg.B group was given fentanyl(0.03～0.08 μg·kg~(-1)·min~(-1))and nitroglycerin(2～5 μg·kg~(-1)·min~(-1))to keep mean arterial pressure(MAP)between 60 to 80 mm Hg till the main procedure of surgery was finished.Observing MAP and HR change before controlled hypotension,during controlled hypoteusion and after stopping controlled hypotension.Observing the time of opening-eyes,remove-tracheal tube and surgical field quality.Results The two groups were comparable with regard to the surgical field rating(P＞0.05).MAP in two groups during controlled hypotension were lower than those before controlled hypotension(P＜0.05),in A group,MAP were comparable with those in B group during controlled hypotension(P＞0.05).In B group there was rellexible tachycardia during controlled hypotension.HR in A group during controlled hypotension was lower than those before controlled hypotension(P＜0.05).HR during controlled hypotension in A group was lower than those in B group(P＜0.01).The time of opening-eyes,remove-tracheal tube in A group was less than those in B group(P＜0.01).ConclusionRemifentanil cound induce and sustain controlled hypoteusion.It was safe and feasible.It was better than nitroglycerin group for controlled hypotension in endoscopic sinus surgery.

ObjectiveTo study the anesthesia effect,safety and reliability of etomidate combined with remifentanil in elderly patients. Methods40 patients scheduled for abdominal operation were divided into two groups with 20 cases each: etomidate group(group A)and propofol group(group B).Anesthesia induction: midazolam 0.04mg/kg,remifentanil 1.5 μg/kg(time＞60s),atracurium 0.6mg/kg,group A to etomidate 0.2mg/kg(30 ～ 60s),(T1),1 min before trachea intubation(T2),1 min after trachea intubation(T3),5 min after cutting skin(T4),5 min after exploration(T5),5min after cutting ill focus(T6),3min after tracheal extubation(T7),30min after operation(T8).At the same time,observed analepsia condition. ResultsIn group B,SBP and DBP were lower than those in group A at T2,T3,T4 and T5(all P＜0.05).In group B,DBP was lower than those in group A at T6 and HR was lower than those in group A at T3 and T7(all P＜0.05).In group B,SBP and DBP were lower than before anesthesia at T2,T3,T4 and T5(all P＜0.05).In group B,DBP was lower than before anesthesia at T6 and HR was lower than before anesthesia at T2(all P＜0.05).In group A,HR was faster than before anesthesia at T7(P＜0.05).The time of openingeyes,remove-tracheal tube in B group was less than those in A group(all P＜0.05).Both groups without memory about operation,anesthesia was content. ConclusionEtomidate combined with remifentanil anesthesia was milder than propofol group to elderly patients ardiovascular effects.It was better than propofol group for elderly patients.

Objective To study the safety and efficacy of laryngeal mask airway(LMA) used in breast cancer general anesthesia. Methods Forty ASA Ⅰ or Ⅱ patients with breast cancer scheduled for selective radical mastectomy under general anesthesia were allocated randomly to either laryngeal mask airway group(group A,n =20) or tracheal tube group(group B, n = 20). SBP, DBP, HR, SpO2 of patients before anesthesia(To)/after intubation immediately (T1) and 5 minutes(T2) after intubation tracheal tube or laryngeal mask intubation/after extubation immediately (T3) and 5 minutes(T4) of after extubation tracheal tube or laryngeal mask were recorded. The different incidence of anesthetic complications and side effect were observed in both groups because intubation and extubation. Results In group B, SBP, DBP and HR were significantly higher than those in group A at T1 and T3 (P ＜ 0.05). Agitation, bucking and pharyngodynia incidence rate in group B were significantly higher than group A(P ＜ 0.05). Conclusion Ventilation with LMA in patients underwent breast cancer radical correction was better than endotracheal intubation general anesthesia in keeping stable hemodynamics and producing less anesthetic complications.

Objective:To study the mechanism of protein kinase C regulating CD44 gene expression in vascular endothelial cells.Methods:Human umbilical vein endothelial cells (HUVECs)were taken as study model.The extract of Raf-1 kinase by immunoprecipitation was used for the Western blot analysis,and its activity was determined by enhanced chemiluminescene assay.CD44 gene expression was detected with RT-PCR,and phosphorylation was measurated by autoradiography.Results:CD44 phosphorylation in HUVECs was enhanced by 10ng/ml PMA treatment as compared with untreated cells, which reached the highest level at 30 minutes. Raf-1 kinase activity increased significantly after exposure to 10ng /ml PMA, and 0.05 ?mol/L Calphostinc could inhibit the role of Protein kinase C(PKC). CD44 gene expression level increased obviously after exposure to 10 ng /ml PMA (PKC activator) for only 1 minute(P

Utilizing disodium phenylphosphate as substrate and determining the amount of phenol set free by its reaction with red B salt, Keplan and Narahara devised a sensitive micro method for the determination of serum alkaline phosphatase. We have studied the method and found it, with a few modifications, convenient and accurate. The chief advantages of this method lie in the fact that it requires serum samples of only 0.01 ml. and a reaction time of only 30 minutes, and that the whole procedure can be completed in one test tube. In order to make the method applicable to the examination of infants and small laboratory animals, we have introduced a glass capillary method for collecting cutaneous blood and separating small amounts of serum, and a micro pipet to deliver 0.01 ml. accurately. With this method, the serum alkaline phosphatase of 55 normal adult Chinese of both sexes ranged from 0.4 to 3.0 units per cc. and averaged 1.68 units with a standard deviation of ? 0.63 units and standard error of the mean of ? 0.09 units. Parallel determinations with Bodansky's method and this method were done on a series of 46 individuals, the ratio of the unitage of serum alkaline phosphatase by Bodansky's method to that by present method was found to be on the average, approximately 2. The serum alkaline phosphatase of a small series of normal rats was found to average 15.2 units per cc. A preliminary trial with rats to ascertain the effect on serum alkaline phosphatase of rachitogenic diet and vitamin D failed to give consistent results. This aspect of the work requires further studies.
