Objective To establish a new and convenient assay for whole blood lead concentration. Methods Whole blood sample was digested by nitric acid-perchloric. Under the condition of pH 0.8～1.0, lead concentration was examined by Hydridegeneration Atomic Fluorescence Spectrometry.Results The method had good linearity when lead concentration were between 0 to 600 ?g/L, r =0.999. The within-run CV of the method for high, middle and low lead level were 4.1%, 3.6% and 3.5% respectively. The between-run CV were 4.9%, 4.6% and 4.7% respectively. The recovery rates were 105.4%, 98.5% and 94.8% respectively. The single-blind test result of series standard lead samples provided by Chinese Academy of Preventive Medicine were within the acceptable range. The detecting Limit of this method was 0.3 ng. There was no significant interference from main two-valence positiveion. The sample can be storage at lest for 1 months at 4℃. Samples of 869 children from Tianjin were tested by this method. The mean value was 91.9 ?g/L, median was 83.8 ?g/L, all data were within 23.1～386.3 ?g/L. The result showed out positive skewness distribution.Conclusion This method were sensitive, accurate, precise, quick and low-cost. It was suitable for use in clinical laboratories.

Objective To observe the effect of early intervention on the oligodendrocyte-myelin glycoprotein(OMgp) mRNA expression of brain injury neonatal rats caused by intrauterine infection.Methods 1.Twenty-eight Wistar pregnant rats were randomly divided into 2 groups:lipopolysaccharide(LPS)-treated group and saline control group.Pregnant rats were consecutively injected with LPS (450 ?g?kg-1) or saline on the 18th gestation age.After birth,the placentas were taken out and made HE staining to observe intrauterine infection.2.Thirty neonatal rats in the saline control group and 55 rats in the LPS-treated group were randomly selected which were divided into intervention group (n=25) and no-intervention group (n=25).The second post-natal day (P2) rats in intervention group were treated by early touch and enriched environment.The neonatal rats in the no-intervention group and saline control group were fed in a routine way.Five cases of P1 rats were selected respectively from the LPS-treated group and saline control group,and brain tissue pathological section was made to observe the condition of brain injury.3.Five cases of P1,P3,P7,P28 and P42 rats were selected from the saline control group,intervention group and no-intervention group to detect the OMgp mRNA expression levels by using the real time polymerase chain reaction me-thod.Results 1.There were a great number of neurophilic granulocytes in the placentas in the LPS-treated group.2.Brain tissue pathological of P1 in the saline control group had complete substantia alba structure,ordered disposition and lightly stained clear chromatospherite.While in the LPS-treated group, there existed brain tissue looseness,colloid cell aggregation and oligodendrocyte cytoreduction in the position of substantia alba,callositas and capsula interna.Intraventricular hemorrhage,substantia alba blood vessel dilatation and blood capillary angiorrhexis and hemorrhage could also be found.3.There was a higher increase in OMgp mRNA expressions of brain tissue in the LPS-treated group at P1,P3,P7,P28,P42 than those in the saline control group (Pa

In order to increase the yield and quality of the medicinal plant and enhance the competitive power of industry of medicinal plant in our country, this paper analyzed the status, problem and countermeasure of the tissue culture of medicinal plant on large scale. Although the biotechnology is one of the most efficient and promising means in production of medicinal plant, it still has problems such as stability of the material, safety of the transgenic medicinal plant and optimization of cultured condition. Establishing perfect evaluation system according to the characteristic of the medicinal plant is the key measures to assure the sustainable development of the tissue culture of medicinal plant on large scale.

Objective To compare the load of EB virus in peripheral white blood cell,plasma and serum in the patients with he-matologic diseases,and to discuss the feasibility of detecting EB virus load by using plasma or serum instead of peripheral white blood cell.Methods Venous blood of 125 patients with hematologic diseases were collected,and peripheral white blood cell,plasma and serum were isolated.The real-time quantitative PCR was used to detect the virus load in three kinds samples with the EB virus load in peripheral blood cell as the gold standard.Results Compared to peripheral white blood,the EB virus load in plasma and ser-um showed no statistical difference(P >0.05).Conclusion Using plasma or serum instead of peripheral white blood cell for con-ducting the quantitative detection of the load of EB virus will be a reliable method.

Objective: To explore the imaging and clinical features of Behcet's disease with coronary artery involvement in order to improve the diagnosis and treatment in clinical practice. Methods: A total of 6 Behcet's disease patients with coronary involvement diagnosed and treated in our hospital from 1999-08 to 2016-11 were analyzed. Coronary angiography (CAG) and coronary CTA were performed for diagnosis. There were 5 cases received CAG and 5 cases received CTA examinations. Results: All 6 patients had the first clinical visit by sudden pericardial tapenade, myocardial infarction or cardiac shock. For diagnosis: the imaging presentation included coronary stenosis, occlusion and pseudo aneurysm formation. 3 patients had anterior descending artery involvement, 1 had the far-end of left circumflex involvement and 2 had the middle segment of right coronary involvement; all patients were combining large amount of pericardial effusion. For treatment: there were 3 patients with aneurysm received conservative treatment (1 case had open thoracic exploration), 1/3 lost contact and 2 having long-term normal life; 3 patients received coronary stent implantation without optimal effect. Conclusion: The patients of Behcet's disease with coronary involvement may easily form pseudo aneurysm; CAG/CTA has been helpful for diagnosis. Clear pre-operative diagnosis of etiology is important for treatment.
