Chongqing Medicine 2017;46(22):3033-3035
Objective To perform mouse pMSV-Slfn5-GFP gene recombinant expression plasmid construction and gene structure analysis.Methods Total RNA was extracted from mouse liver and turned into cDNA by reverse transcription.Mouse Slfn5 coding sequence (CDS) fragment was amplified by PCR and connected with the pGEM-T Easy vector.The connected product was transferred the E.coli DH5a.The positive clones were selected for extracting plasmid,which was identified by double enzyme of restriction endonuclease Hpa Ⅰ and Xho Ⅰ.Then correct plasmid identified by enzyme digestion was sequenced by Macrogen USA.Then correct plasmid by sequencing was connected with pMSV-GFP by HindⅢ and Xbo Ⅰ,which was named as pMSV-Slfn5-GF.UCSC (http://genome.ucsc.Edu/) was used to analyze mouse Slfn5 and its family genomic structure.Slfn5 protein structural domain was determined by NCBI.Results Slfn5 full-length gene sequence was cloned into the expression vector pMSV-GFP,the fragment size was about 2.65 kb by enzyme digestion identification.The conservatism of AAA_4 protein domain in Slfn5 protein family was determined by phylogeny.fr.Conclusion Mouse full-length gene pMSV-Slfn5-GFP expression vector is successfully constructed.

ObjectiveTo investigate the effect of different dosage recombinant human erythropoietin(rhEPO),an angiogenesis-like factor,on pulmonary angiogenesis exposed to hyperoxia in newborn rats.MethodsSixty Sprague-Dawley newborn rats were randomly divided into four groups:air group (room air exposure,n =15 ),hyperoxia group ( exposed to 95% oxygen,n =15 ),hyperoxia + large dosage rhEPO group (received rhEPO 5000 U/kg,intraperitoneally on 1 hour before and 3 days after exposed to hyperoxia,n =15) and hyperoxia + small dosage rhEPO group (received rhEPO 800U/kg,the same time points,n =15 ).The isodose of saline were given intraperitoneally on the same time points in the air group and the hyperoxia group.After 6 d of exposure,the survival rate was compared,CD31 and vascular endothelial growth factor (VEGF) were measured by immunohistochemistry to assess hyperoxia-induced changes in lung morphology.ResultsAfter 6d of exposure,hyperoxia + large dosage rhEPO group prolonged the survival rate in comparison with the hyperoxia group [ 86.7 % ( 13/15 ) vs 60.0 % ( 9/15 ) ].The expression of lung CD31 [ ( 38.69 ±1.69)% vs (33.57±4.12)%,P<0.05] and VEGF (124.4296±7.2823 vs 114.2059 ±-8.345 7,P<0.05) in newborn rats treated with large dosage of rhEPO was significantly higher than those in hyperoxia group.While there was no significant difference of CD31 [ ( 36.34 ± 1.89 ) % ] and VEGF( 115.429 6 ± 6.719 9) in small dosage rhEPO group compared with the hyperoxia group (P>0.05 ).ConclusionInstead of treatment with small dosage rhEPO (800 U/kg),large dosage rhEPO (5000 U/kg) may have important protective effects on pulmonary angiogenesis in hyperoxia-induced lung injury of newborn rats.

Objective To understand the death rate and the main death causes of the senile diabetic inpatients. Methods The histories of all the death cases of senile diabetic inpatients in this hospital from 1992 to 1999 were reviewed. The death rate and causes of senile diabetics were compared with those of the non-senile diabetics. Results Senile diabetics among the total diabetic inpatients increased within 8 years (56.93% during 1992-1995 vs. 67.63% during 1996-1999,P80 yrs group being 23.60%, P

Objective To find out the difference between fetal malnutrition (FM) and small for gestational age (SGA) and its clinical significance. Methods Clinical nutritional status was assessed in 548 singleton term babies. Nine superficial, rapidly detected signs of malnutrition were taken for the clinical assessment nutritional status score (CANSCORE). FM was diagnosed if the total score was less than or equal to 24. Results Among 40 SGA, 21(52.5%) were FM, the other 19 (47.5%) were not FM with scores more than 24, whereas 13(2.8%) out of 508 AGA (appropriate for gestational age) were FM. Conclusion SGA and FM are not synonymous and FM can be rapidly determined by the CANSCORE. Biochemical and ultrasonic studies should be done in high risk preg nancy during second trimester to discover FM and intervene by nutritional treatment to prevent the infants with FM.

Objective To observe the features of the manifestations of fundus fluorescein angiography (FFA) in multiple sclerosis (MS) and their value in clinical diagnosis. Methods The clinical data of 42 patients (84 eyes) with MS diagnosed by magnetic resonance imaging (MRI) and examination of cerebrospinal fluid (CSF) were retrospectively analyzed. The clinical data included visual acuity, ocular fundus examined by direct ophthalmoscope after mydriasis, FFA, visual field, CSF,visual evoked potential (VEP) and MRI examination. Results In 42 patients (84 eyes),the positive detectable rate of examination of direct ophthalmoscope, CSF, visual field, VEP, and MRI was 36.9%, 21.4%, (71.4%, and) 83.3% respectively. Abnormal results of FFA were found in 44 eyes (52.38%), including papillitis in 4 eyes (4.76%)at the early stage with extended physiological scotoma and central scotoma; neuroretinitis in 7 eyes (8.33%)at the medium stage with central or para- central scotoma; optic atrophy in 33 eyes(39.29%) at the late stage with centripetal constriction and even tubular visual field. Conclusion The main angiographic features of MS are papillitis, neuroretinitis and optic atrophy. The manifestations of FFA combined with the results of examination of CSF,visual field, VEP and MRI is helpful for comprehensive and exact diagnosis of MS.

Objective To establish a simple and rapid new method for DNA extraction of FTA bloodstain samples.Methods Genomic DNA was extracted from FTA bloodstains of 1.2mm diameter by FTA-DNA direct extraction and FTA routine method respectively,and their genotypes were analyzed using ABI IdentifilerTM kit in 10?l and 25?l of reaction volume respectively.Results For 25?l of reaction volume,all DNA extracted by two different methods was successfully genotyped.For 10?l of reaction volume,however,the typing success rate of DNA extracted by FTA routine method was significantly lower than those by FTA-DNA direct extraction procedure.Using FTA routine method,the value of RFU ranged from 100 to 2000,and the peak imbalance result from preferential amplification of the smaller allele was a common phenomenon.Moreover,allelic dropout occurred in approximately nineteen percent of samples,and this was not obviously improved even if performed by automatic DNA workstation.However,using FTA-DNA direct extraction procedure,the typing results were similar to those in 25?l of reaction volume,and better results can be obtained using automatic DNA workstation.Conclusion The FTA-DNA direct extraction method is simple and rapid,and can be used to automatic establishment of DNA database with FTA bloodstains.
