Objective To clone the genes related to pregnancy induced hypertension (PIH) for the study of PIH pathogenesis. Methods The differential expressed cDNA of PIH and normal pregnant placenta were cloned using modified polymerase chain reaction based subtractive hybridization. The differential cDNA were sequenced. Results Ammong 86 clones from subtractive hybridization, 14 clones containing differential expressed gene fragments in PIH and normal placenta were identified, and these might be the genes associated with PIH. Compared with the expressed sequence tags (EST) in dbEST of National Center for Biotechnology Information, it showed that 11 of them were known gene fragments, and three were unknown. The three unknown gene fragments were registered in GenBank, the accession number is AF 232216, AF 232217, AF 233648 respectively. Conclusions Fourteen PIH related genes were cloned with subtractive hybridization. A new approach to study on the pathogenesis of PIH is presented.

Objective To explore the feasibility of nasolabial sulcus flap transfer with autologous free skin graft to repair the alar defects after malignant tumor resection.Methods From January 2012 to January 2015,9 patients with malignant tumor were treated in the hospital.After complete tumor removal,the defect area being reconstructed was 1.5 cm × 1.3 cm to 2.5 cm × 2.5 cm.The defects of 9 patients were all restored with nasolabial sulcus flap combined with autologous free skin graft.Results The 9 patients were followed up for 6-18 months postoperatively.The nasolabial sulcus flap and autologous free skin graft were survived completely in all cases.Symmetrical alae were noted with slight edema within nasal cavity but without difficult ventilation.Scar was repaired in phase-two surgery.Conclusions Nasolabial sulcus flap combined with autologous free skin graft is an optional way in alar defects restoration.Further with secondary morphologic plasty,satisfactory surgical outcome can be achieved.

OBJECTIVE: To optimize the process for extraction and purification of Schisandrin in Fructus Schisandra Chinensis. METHODS: The orthogonal test L9( 34) was adopted to optimize the water extraction process using Schisandrin and its extracts as indicators. The parallel test was used to optimize the parameters of the alcohol precipitation technique. RESULTS: The optimized process for extraction and purification of Schisandrin was as follows: extracting three times using 10- fold water, 1. 5h each time, with filter liquids concentrated to 1. 4g of crude drug mL- 1 then precipitated to 80% ; filtering alcohol liquids, and adjusting pH value to 7. CONCLUSIONS: This method can be used as a reference for the extraction of Fructus Schisandra Chinensis.

OBJECTIVE:To study the stability of omeprazole sodium solution for injection under the influence of metal ion calcium and magnesium.METHODS:HPLC was adopted to determine the variation of the content of omeprazole sodium solution acted by metal ion calcium and magnesium of different concentrations in different time.The change in colour and luster was also observed.RESULTS:Omeprazole sodium solution tended to disintegrate rapidly along with the prolonging of time,and increase with the increasing of concentration;when Mg2+ was added,change in color was seen,with no degradation substance produced;when Ca2+was added,change in color was also seen,with white deposit produced.CONCLUSION:Ca2+ and Mg2+ show significant influence on the stability of omeprazole sodium solution.

OBJECTIVE:To systematic review the relationship between CYP4F2 gene polymorphism and warfarin maintenance dose in Chinese population,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from Cochrane library,PubMed,EMBase,CJFD,VIP and Wanfang database,studies about the relationship between CYP4F2 gene polymorphism and warfarin maintenance dose in Chinese population were collected,and Meta-analysis was performed by using Rev Man 5.0 statis-tics software. RESULTS:A total of 13 studies were included,involving 2 958 patients. The type of gene was type TT,type CT and type CC. Results of Meta-analysis showed the relationship between 3 gene polymorphism and warfarin maintenance dose was type TT>type CT>type CC,and there were significant differences among groups. CONCLUSIONS:CYP4F2 gene polymorphism in Chinese population has significant correlation with warfarin maintenance dose. However,due to the limit of methodological quali-ty,large-scale and high quality studies are required for further validation of the conclusions.

BACKGROUND:In rabbit femur fracture model experiment, there are a few studies on whether quadriceps tendon wil affect the stability of the fixed device. OBJECTIVE:To analyze the effects of quadriceps tendon to the stability of external fixator in rabbit models of femur fracture. METHODS:The 48 New Zealand white rabbits were randomly divided into two groups. External fixator was used to make fracture model. In the experiment group, quadriceps tendon was cut. In the control group, quadriceps tendon was retained. 2 weeks later, X-ray examination was utilized to observe the number of failed external fixator in both groups from modeling to success. RESULTS AND CONCLUSION:(1) X-ray examination:2 weeks after model establishment, external fixation frame screw was free from femur in one rabbit of the experiment group, and seven rabbits in the control group. Of them, one screw was broken. Threaded portion retained in the femur. (2) External fixation failure rate:failed external fixator was found in one rabbit in the experiment group, resulting in a failure rate of 4%, and 12 rabbits in the control group, resulting in a failure rate of 50%(P<0.05). These findings suggested that cutting off the rabbit quadriceps tendon can effectively ensure the stability of the external fixator, and indirectly improve success rate of the experiment.
