Objective To discuss and validate which method is more effectiveness for central placenta previa through analysing the clinical outcomes of the management of hemorrhage between uterine packing and stitching hemo-stasis during cesarean section.Methods 48 pregnant women with central placenta previa was conducted in this ret-rospective study,which were all cesarean section delivery.These patients were divided into two groups.24 patients with uterine packing with gauze in the control of massive hemorrhage during cesarean section were indetified,other-wise,the other 24 patients were conducted with sewing and ligation uterine.And then,the effectiveness and outcomes were compared.Results These all patients were alive and keep the uterus.The average estimated blood loss of the stiching group was (554 ±327)mL,obviously less than the uterine packing group,which was (828 ±584)mL,and the difference was statisatically significant (t =6.689,P<0.01 ).The rate of blood transfusion during operation was 8.33% (2/24)in the group of stiching,and was 50.0%(12/24)in the uterine packing group(P<0.05).Similar-ly,the operation time of the stiching hemostasis group,which was (48.9 ±10.0)min,was evidently shorter than (68.3 ±13.3)min of the other group(t=8.126,P<0.01).The two groups had no significant difference in therate of primary healing of incision,postoperative fever and admission time(P>0.05).Conclusion The uterine stiching is an effective,rapid and simple technique in the control of hemorrhage of central placenta previa.

Objective To explore the difference of myeloperoxidase(MPO)detection results among different types of samples , anticoagulant selection and comparison of detection results .Methods The plasma samples containing EDTA‐K2 or heparin and ser‐um samples of common biochemical tube without containing anticoagulant were collected from 165 persons undergoing healthy physical examination .The MPO level in 3 kinds of sample was detected .Then the detection results in each group were performed the statistical analysis .Results The MPO detection results had statistical difference between plasma samples with different antico‐agulants and between plasma samples with different anticoagulants and serum sample without anticoagulant in the same person (P<0 .05) .Conclusion Different samples types have larger difference in M PO detection results .It is suggested that each laboratory should formulate the corresponding reference intervals according to different anticoagulants ;because EDTA‐K2 anticoagulation plasma is not affected by the release of MPO from in vitro leukocytes ,it is recommended to adopt EDTA‐K2 anticoagulation blood as the first selected of M PO level detection .

Objective To investigate the changes of oxidized low density lipoprotein(oxLDL) and C-reactive protein(CRP) and their correlation in patients with acute coronary syndrome(ACS),and explore their roles in the pathogenesis of ACS. Methods The plasma levels of oxLDL and CRP were measured in 95 patients with ACS and 66 control subjects by ELISA. Results oxLDL and CRP levels were significantly higher in patients with ACS than those in control group(P

Objective To investigate the surgery opportunity choice of congenital esotropia.Methods A retrospective research was taken using the clinical data and the results of the treatment of 146 inpatients with congenital esotropia in our department from Mar 2012 to Mar 2015.The correction rate,lackingcorrection rate,and over-correction rate were compared between early surgery group and late surgery group on time of 1 week after surgery and 6 months after surgery,respectively.Results In all the 146 patients,88 (60.3%) had an esotropia deviation greater than or equal to 40 pupil distance (PD),38 (26.0%) combined with amblyopia,12 (8.2%) combined with nystagmus,30 (20.5%) combined with inferior oblique muscle overaction,6 (4.1%) combined with dissociated vertical divergence (DVD).There was no significant difference between early surgery group and late surgery group on correction rate,lacking-correction rate,and over-correction rate on the time of 1 week after surgery and 6 months after surgery,respectively.Conclusions Congenital strabismus should take surgery at the early-stage,especially for those have large angles.It is better to be operated before 2-year old for a better formation and recovery of binocular visual function.

objective To determine the existence of virulence-associated invA gene in different genospeeies of Leptospira interrogans reference strains in China.and to understand the alterations of invA gene transcription and expression of L.interrogans strain Lai before or after infecting cells.Methods PCR was applied to detect the invA gene of four L.interrogans strains belonging to four different genospecies and L.biflexa strain Patoc Ⅰ.The entire invA genes from the L.interrogans strains were cloned and then sequenced.The prokaryotic expression system of invA gene of L.interrogans serogroup Icterohaemorrhagiae serovar Lai strain Lai was constructed.Using Ni-NTA affinity chromatography,the target recombinant protein rInvA was extracted and purified.Rabbits were immunized with rInvA to obtain antiserum and the titer of antiserum was determined by immunodiffusion test.A model of L interrogans strain Lai infecting human embryo kidney cell line HEK293 was established to detect the alterations of invA gene transcription and expression of the leptospiral strain before or after infecting the host cells by real-time fluorescent quantitative RTPCR and western blot assay.Results All the four tested L.interrogans strains had invA gene whereas L.biflexa strain Patoc Ⅰ not.The similarity of nucleotide and putative amino acid sequences of invA genes from the four L.interrogans strains belonging four different genospecies were 99.33%-100%and 98.66%-100%,respectively.The constructed prokaryotic expression system could efficiently express rInvA and the immunodiffusion titer of rabbit anti-rInvA serum was 1:16.After L.interrogans strain Lai infecting HEK293 cells for 30 min or above,the microbe could adhere the surface of the cells.On the 30 min after the infection,the mRNA level of invA gene of L.interrogans strain Lai was remarkably upregulated,and on the 45 min after infection the mRNA level presented a peak value and then graduated decreased.On the 45 min or 60 min after L.interrogans strain Lai infecting HEK293 cells,InvA protein could be detectable but before infection or after infection for over 90 min the InvA protein expression was negative.Conclusion The invA gene is a unique gene for pathogenic L.interrogans.The invA gene of L interrogans has characteristics of cell-touched expression and transient expression,which may have a close correlation with adhering and invading host cells.
