Objective In acidity condition, arsenic and mercury can react on newly produced H2 to produce hydride which can be detected by atomic fluorescence spectrometry. The goal of the present paper is to establish a method to determine arsenic and mercury of the water at one time. Methods A quantitative method for determination by hydride generation-atomic fluorescence spectrometry was used .The electric current of the arsenic and mercury lamp were all 80 mA. The ratio of main arsenic electric current with the assist one was 50:30. 1% KBH4 of 0.2% NaOH solution were used as the reducers. Results The linear range of the arsenic was 0-10 ?g/L with correlation coefficient r=0.999 9. The RSDs and recovery rates of the arsenic were 2.0%-5.3% and 84%-113% respectively. The mercury showed a good linear result in the range of 0-5 ?g/L either, and the correlation coefficient was 0.999 3. The RSDs and recovery rates of the method were 1.9%-5.7% and 84%-107% respectively. Conclusion This method is simple, rapid, sensitive and accurate. It can determine arsenic and mercury in water at one time.

OBJECTIVE:To study the effect of kallidinogenase on senile diabetic nephropathy.METHODS:95senile cases with diabetic nephropathy treated with the basic therapy were randomly divided into treatment group(plus kallidino?genase)and control group(plus aspirin),the proteinuria ejection level,hemorheological parameters and blood lipid level of2groups in24hours were investigated before and after treatment.RESULTS:As compared with prior treatment and the coutrol group,the proteinuria ejection level decreased significantly,the hemorheology improved and the blood lipid level decreased in the treatment group.CONCLUSION:Kallidinogenase is effective to some degree in the prevention and cure of senile diabetic nephropathy and diabetic macroangiopathy.

BACKGROUND:Hematopoietic stem cel transplantation is a promising treatment for a variety of malignant and nonmalignant disorders. But noninfectious pulmonary complications folowing hematopoietic stem cel transplantation are a major cause of morbidity and mortality in these patients. And the diagnosis and treatment are difficult. OBJECTIVE: To review the noninfectious pulmonary complications after hematopoietic stem cel transplantation in terms of onset time, risk factors, clinical manifestations, characteristics of the high-resolution CT, histopathological measurement, related genes and treatment options. METHODS: A computer-based search of VIP, PubMed and Sciencedirect databases was performed for articles related to noninfectious pulmonary compli cations after hematopoietic stem cel transplantation published from January 2005 to October 2014. The key words were “HSCT, pulmonary complications, non-infectious, pirfenidone” in Chinese and English in the title and abstract. Finaly, 31 articles were included in result analysis. RESULTS AND CONCLUSION: The incidence of noninfectious pulmonary complications after hematopoietic stem cel transplantation has become more and more, with atypical clinical manifestations and limited diagnosis and treatments. According to the different clinical onset time, diagnostic criteria, clinical manifestations and the appropriate laboratory tests, clinicians can make early diagnosis and early intervention. Especialy, the usage of high-resolution chest CT and bronchofiberscope for bronchoalveolar lavage as wel as the timely drug administration can improve the survival rate of patients with noninfectious pulmonary complications after hematopoietic stem cel transplantation.

Objective To establish the analytical methods for determining the contents of tannins in different vegetative organs of Abutilon indicum (L.) Sweet. Methods The content of tannins, expressed as gallic acid equivalents, was measured by using the phospho molybdenum tungstic acid-casein colorimetry. Results The good linearity between concentrations and absorbances of gallic acid was found in the range of 2～10 mg/L, the average recovery was 99.63% and RSD was 1.08%, the contents of tannins in leaves, stems and roots of Abutilon indicum (L.) Sweet were 0.34%, 0.16% and 0.27% respectively. Conclusion The proposed method is sensitive, precise, accurate and reproducible, and it is suitable for the determination of tannins in Abutilon indicum (L.) Sweet.

A case of a patient with a unilateral maxillary defect and restricted mouth opening was presented. The two-stage hollow maxillofacial prosthesis can be used to restore the above defect, thus promoting mastication, speaking, swallowing, and sucking, as well as improving the patient's appearance. Satisfactory results were achieved.

Geometrically virtual models of three-dimensional blood flow field and eight types of mesh stent (different porosity and different stent shape) were constructed using SoildWorks software, and simulation of stented models were performed respectively using finite element software ANSYS11.0 according to computation fluid dynamics method. The flow resistance of the semi-circular section stent model of blood flow from the semi-circular planar surface was greater than the reverse in a certain range of permeability. However, the result was the opposite when the porosity increased to a specific value. For both grid-stent model and sine-stent model, flow resistance of blood that flowed from the stent in both directions increased with the porosity reduction. Under the same porosity and the direction of blood flow from the same stent, the flow resistance of the grid stent model was 1.5 times greater than the sine-stent model. Results showed that there are different effects on the flow resistance in blood flow in different directions from the semi-circular section stent model.

Shasheng is a common Chinese drug used as antitussive and expectorant. A survey showed that the original plants of Shasheng on the current market consist of more than 30 species. To appraise the qualities of Saasheng scientifically, the antitussive .and expectorant activities of ten species of Shasheng were compared. Rosults showed that the EtOH extracts of the roots of Glehnta littoralis, Adenophora stricta subsp. henanica, A. potaninii and A .liliifolioides are very effective as autitussive,while those of A .liliijoliolioides,A.stricta subsp. sessilifolia and A. potaninii are very effective as expectorant.

[Objective]To introduce the treatment and result of meniscal cyst by arthroscopic surgery.[Method]During the period between 1997 and 2005,20 patients suffered from meniscal cysts have been treated by arthroscopic surgery in Xijing Hospital.Meniscal cysts were excised in all cases with shaver under arthroscopic visualization,whereas outside-in suture repair of meniscus was undergone in 8 cases to close the lacuna and repair the meniscal peripheral free which were resulted from remoral of cyst.The patients were followed up from 3 to 42 months with an average of(18.7?12.2)months.The patients were assessed pre-and post-operatively by the Lysholm score and Glasgow Assessment.[Result]Sixteen of total 20 patients were followed up.Meniscal cyst recurred in a patient one year after operation.Lysholm score of the 16 patients showed a significant improvement from(71.2?8.7)pre-operation to(97.1?2.9)post-operation(t=32.948,P
