Objective To clone amastin coding genes from different strains of Leishmania parasites. Methods Using amastin cDNA sequence as the reference, dbEST data base established by National Center Biotechnology Information (NCBI), USA, was searched by BLAST tool. A 309 bp DNA fragment of Leishmania major was found and used as the probe for the screening of a DNA library. The amastin gene of Leishmania major Abdou was cloned and sequenced. Specific primers were designed and amastin genes for Leishmania mexicana WR972, Leishmania brizeliensis and Leishmania amazonensis joseph were amplified by polymerase chain reaction. Results The amastin genes from 4 strains of Leishmania parasites were cloned and sequenced. It was found that all 4 amastin genes contained unique open reading frame of 552 bp and encoded amastin protein of 183 amino acid residues. Conclusion The amastin genes of 4 strains of Leishmania parasites were successfully cloned.

Objective Ritodrine hydrochloride(RH) combined with radix salviae mihiorrhisa(RSM) is ap- plied to treat fetal growth ristriction(FGR). Curative effect was recorded during observation. Methods 62 pregnant women with slowly growing fetuses were divided into two groups randomly. Group A(test group) :including 31 preg- nant women who received RH combined with RSM treatment. Group B(control group) :including the other 31 preg- nant women who only received RSM treatment. Group B received 250ml of fat emulsion injection. One time every three days within one week. At the same time,gronp B also received injection of 500ml 10 % dextrose, coenzyme A 100U ,ATP 40mg,vitamin C 2g,dextran-40 and compound salvia injection 10ml one time a day,ten days in all. Be- sides the above-mentioned medicament for group B, group A received RH 100ml injection every day. Ten days was a period of treatment. After the treatment, uterine height, abdominal circumference, weight were measured and bipari- etal diameter, head circumference, abdominal circumference were checked by B-type ultrasonic inspection. After birth,weight of the baby and weight of placenta were measured too. Results Measurement indexes from group A, weight of the new-born baby and weight of placenta are obviously higher than those from group B. Conclusion RH combined with RSM can obviously extend blood vessel, loose placenta, improve blood circulation, accelerate cell metabolism, make microeirculation better, reduce permeability of capillary vessel, keep placenta's function and help foetus' growth.

Methods　 The rAAV/enhance green fluorescein protein (EGFP) recombinant was prepared by the routine method of two plasmids cotransfection. Results　 The experiment showed that one 10cm plate could produce 107-108 infection unit recombinant by the method of two plasmids cotransfection, and the transduction of HepG2 cell was increased with the increase of infection dosage of rAAV. About 100 multiplicity of infection (MOI) AAV vector could make all the tumor cell light. Conclusion　 Liver cancer cell can be efficiently transduced by rAAV, and AAV vector may be a valuable vector for the gene therapy of liver cancer.

Objective To investigate the distribution of complications and the relationship with neurologic subtype and gross motor function in preterm infants with cerebral palsy (CP). Methods The type, grade of Gross Motor Function Classification System (GMFCS), intelligence,speech, ophthalmologic consultation, brainstem auditory evoked potential and electroencephalogram of 135 preterm infants with CP were reviewed. Results There were 284 complications in total, (2.10±1.33) per child, and was significantly different among various types of CP (F=5.50, P<0.001). The incidence of mental retardation and speech disorder was significant different among various types (P<0.05). The incidence of mental retardation, speech disorder, visual impairment and epilepsy increased significantly (P<0.05) in spastic quadriplegia infants,compared with those with diplegia and hemiplegia. The incidence of mental retardation, speech disorder, visual impairment and musculoskeletal disorder was significantly different (P<0.05) among various grades of GMFCS. The frequency of complications was more in children unable to walk (GMFCS Ⅳ~Ⅴ) than able to walk (GMFCS Ⅰ~Ⅲ) for children over 2 years old (t=70.05, P<0.001). Conclusion The incidence of mental retardation, speech disorder, visual and hearing impairment, secondary musculoskeletal disorder and the multiple disorders are related with neurologic subtype and/or the grade of GMFCS.

OBJECTIVE:To provide the basis for the formulation of the health intervention strategy for medical and health insti-tutions'pharmacists and provide reference for other related research. METHODS:A total of 180 medical and health institutions' pharmacists in Heilongjiang province were investigated and evaluated by work satisfaction MMSS scale(modified)and quality of life(SF-36)scale,and the relevant data were analyzed statistically. RESULTS:A total of 180 questionnaires were distributed and 134 valid questionnaires were collected. The effective recovery rate was 74.44%. The average score of work satisfaction degree was (3.44±0.79),which was at the middle level. The highest score was the relationship with colleagues and the lowest score was wel-fare. The physical function,the physiological function and the social function dimension of the respondents were higher thanChi-nese norm. The scores of physical pain,general health,vitality,emotional function and mental health were lower thanChinese norm,and there was statistical significance between the scores of the other dimensions andChinese norm(P<0.05),except for the physiological function and vitality dimension. Multivariate analysis showed that gender,duties,education,length of service and work satisfaction score had an effect on quality of life(P<0.05),among these factors,work satisfaction score was positively correlated with quality of life. CONCLUSIONS:The quality of life of medical and health institutions'pharmacists still needs to be improved,which is related to many influential factors,and job satisfaction is an important influential factor.
