Purpose:To study the secretion and gene expression of Angiogenesis factors in the patients with CML and study the effect of Angiogenesis in the occurrence and development of CML. Methods:Concentration of VEGF in peripheral blood was determined by using ELISA. Myeloid tissue was extracted from all CML cases and ITP patients to detect MVD by using CD34 labelling. At the same time the level of VEGF,b-FGF were detected by using RT-PCR in both peripheral blood and myeloid cells.Results:Our results showed that the concentration of VEGF was obviously higher in the peripheral blood of CML patients(177.53?153.45 pg/ml) than in those of control group(73.12?19.82 pg/ml). The gene expression of VEGF and b-FGF were both higher than those of control group. The difference has statistical significance(P

Objective To provide basic and scientific data for diagnosis of Kashin-Beck disease (KBD) and development of children in the endemic disease region of Xinghai, Qinghai Province. Method In March 2012, the radiographs of right hand of 278 children aged 7 - 12 in KBD areas from Xinghai County, Qinghai Province were taken by X-ray, and then these phalange bones were measured with electronic digital vernier caliper. All data were analyzed with SPSS 17.0. Results The length of middle and end phalanges offingers of the forefinger, middle phalanges offinger of the middle finger and middle phalanges offinger of the pinky of girls aged 8 [(15.76 ± 1.39), (10.86 ± 1.06), (18.69 ± 1.46) and (12.26 ± 1.51) mm] were higher than those of boys [(14.71 ± 0.96), (10.24 ± 0.87), (17.76 ± 0.99) and (11.27 ± 1.42) mm], and the differences were statistically significant (t = 3.058, 2.174, 2.603, 2.346, all P< 0.05). The length of end phalanges offinger of the forefinger and middle phalanges offinger of the ring finger of girls aged 11 [(12.37 ± 0.86), (19.71 ± 1.32) mm] were higher than those of boys [(11.56 ± 1.01), (18.67 ± 2.03) mm] with significant differences (t = 2.938, 2.070, all P< 0.05). There was no significant difference of length of phalange bones between boys and girls at other age groups (all P>0.05). 7 year old age group, the width of phalange bones(proximal thumb, middle phalanges offingers of the forefinger, proximal and end phalanges offinger of the middle finger, proximal phalanges offinger of ring finger and middle phalanges offinger of the pinky) of boys was significantly thicker than girls (t = 2.291, 3.151, 3.131, 2.814, 2.235, 2.129, all P < 0.05). The 8 year old age group, the width of proximal phalanges offinger of ring finger of boys was significantly thicker than girls (t = 2.952, P< 0.05); 10 year old age group, the width of proximal phalanges offinger of the middle finger, proximal and middle phalanges offinger of ring finger of boys was significantly thicker than girls (t = 2.114, 3.829. 2.234, all P< 0.05); 11 year old age group, the width of middle phalanges offinger of forefinger and ring finger of boys was significantly thicker than girls (t = 3.219, 2.094, all P< 0.05); 12 year old age group, the width of end phalanges offinger of thumb and forefinger, proximal and end phalanges offinger of the pinky of boys was significantly thicker than girls (t=2.181, 3.973, 3.128, 2.237, all P<0.05);the rest and comparison, no statistically significant difference (P>0.05). Conclusion The development of phalange bones of children aged 7 - 12 is in accordance with the specific changes of development at different stages.

OBJECTIVE:To provide reference for the realization of normalization and standardization of quality control and management of Pharmacy intravenous admixture service(PIVAS). METHODS:The management and effectiveness of PIVAS quali-ty control in our hospital were introduced from aspects of the establishment of internal quality control system,the key indicators and effects of quality control. RESULTS:According to checking items from aspects of examining once in a month,on prescription checking,preparation,infection control,equipments,drugs,consumable materials,sanitation;holding 1 monthly quality control reviews;and analyzing unqualified indexes and existing security risks,the quality control of PIVAS had achieved good results. The qualified percentage of quality control index was increased from 84%(Jan. 2016)to 90%(Jun. 2016),error rate in the same peri-od was decreased from 0.579‰ to 0.099‰. CONCLUSIONS:Developing quality control of the implementation of detailed quality control key indexes for the whole process of intravenous infusion in PIVAS can effectively regulate the position working process,re-duce preparation error and ensure the quality of infusion preparation.

In recent years, many modern spectral databases for complex materials ( such as soil, feed, forensic evidence materials, pharmaceuticals and oils) have been established based on molecular spectroscopy (UV, infrared, near infrared, Raman and fluorescence) both at home and abroad, which are playing more and more important roles in the agricultural and industrial production and science research. Spectral searching method is one of the key technologies to make full use of the molecular spectral database. This paper reviewed the progress in the basic and modified algorithm, strategy and application of molecular spectral searching methods, and put forward the scientific and technological problems that need attention and further research.
