Objective:To determine the prevalence of Salmonella paratyphi C phage ( SPC-P1 ) in dif-ferent Salmonella serovars and to identify the integration sites in host genome. Methods: Based on the complete genome of SPC-P1 in S. paratyphi C RKS4594, 6 pairs of primers were designed and used to amplify the fragments of SPC-P1 in 11 S. typhi, 11 S. paratyphi A, 12 S. paratyphi B and 23 S. para-typhi C strains. At the same time, 100 complete genomes of Salmonella including 20 serovars available in National Center for Biotechnology Information ( NCBI) database were downloaded and aligned by Mauve 2. 3. 1 to determine the prevalence of SPC-P1 in these serovars. Primers were designed according to the integration sites of SPC-P1 in the genome of RKS4594 , and used to amplify ten strains having SPC-P1 in the genome. The PCR products were sequenced to investigate the integration sites of SPC-P1. Results:SPC-P1 was widely distributed in S. paratyphi C genome. In the study, 14 strains had all 6 fragments and 2 strains had 3-5 fragments. All the amplified fragments showed expected sizes. In contrast, in the ge-nomes of S. typhi, S. paratyphi A and S. paratyphi B, no or only 1-2 fragments could be amplified, and the sizes were smaller than expected. The results from Mauve showed that only in the genome of S. choleraesuis, which was a close relative of S. paratyphi C, there existed an almost complete genome of SPC-P1. The insertion site of SPC-P1 in all the ten S. paratyphi C strains tested was between pgtE and yfdC genes. Conclusion:SPC-P1 is a unique virulence factor of S. paratyphi C. It may play roles in the host range and pathogenicity of S. paratyphi C.

[Objective] The purpose of this study was to evaluate the association of ultrasound findings and different treatments with the prognosis of the pump twin in twin reversed arterial perfusion sequence (TRAP).[Methods] The 55 cases that were diagnosed as TRAP during the period from January 4th 2010 and August 31st 2015 were included.Ultrasound appearances of monochorionic twins were documented in detail when the twins were diagnosed with TRAP initially.At the initial evaluation,presence or absence of the following abnormalities were documented,including the ratio of the acardiac twin to the weight of the pump twin,hydrops fetalis in the pump twin,cardiomegaly in the pump twin,polyhydramnios in the pump twin,oligohydramnios in the acardiac twin and different treatments.The relationship between these ultrasound characteristics and different treatments with mortality of pump twin were analyzed with logistic regression.[Results] A total of 55 cases with TRAP were diagnosed in our institution and three cases were lost to follow up.Selective reduction was performed in 21 cases,termination of pregnancies in 13 and expectant management in 18.Excluding the cases that underwent termination of pregnancy,the remaining 39 cases were divided into two groups according treatment,expectant management group (n=18) and selective reduction group (n=21).Overall survival rate of the pump twin in these two groups was 66.7％ and 71.4％,respectively,P =0.748.The markers of perinatal outcome were not significantly different between expectant management group and selective reduction group.Logistic regression demonstrated that cardiomegaly in the pump twin (OR=21.73,95％CI:1.15 ～ 203.89,P ＜ 0.001) were significant correlated with mortality of the pump twin.[Conclusion] The prognosis markers were not significantly different between conservative management and selective reduction group.Cardiomegaly in the pump twin should be considered as risk predictors for mortality of the pump twin in TRAP.

Objective To observe the effect of Fuming Tablet on the content of ATP and MDA, and the activity of SOD in retinal tissue of rabbit retinal detachment (RD) and reattachment model. Methods 48 rabbits were randomly divided into 4 groups, with 12 in each. 12 rabbits were taken as healthy control and fed with normal saline, the others in model group, western medicine group and Fuming Tablet group were prepared as RD model by injecting Sodium Halyuronate (Helen) into subretinal spaces, and the detached retinas were reattached automatically in 10 ～ 14 days. They were administered with normal saline, mixed preparation of western medicines and Fuming Tablet suspension respectively, then the content of ATP, MDA and SOD activity were determined in postoperative 1 week (the retina remained detached) and 3 weeks (the detached retina reattached). Results Effect of fuming tablet of increasing the content of ATP and the activity of SOD, reducing the content of MDA was similar with that of the mixed preparation of ATP, VitB1 and Venoruton. Conclusion Fuming Tablet can significantly improve the oxidation resistance and depress the lipid peroxidation of retinal tissue, thus alleviate and inhibit the development of retinal pathological changes to some extent.

Huoxue Tongmai Lishui method, a traditional Chinese medicine treatment for eliminating water, activating and promoting blood circulation, could inhibit fundus hemorrhage on experimental retinal vein occlusion (RVO) with high obvious effective rate, and improve symptoms in traditional Chinese medicine. The action mechanism may be related to reducing plasma viscosity and non-perfusion area, and the formation of collateral circulation.

Objective To observe the extracellular content of dopamine (DA)and expression of D1 receptors in hippocampal dentage gyrus (DG)in the model rats with vascular dementia (VD),and to investigate the relationship between them.Methods 12 male SD rats were randomly divided VD group and sham-operation group,and the VD model was prepared by permanent bilateral carotid occlusion.The extracellular content of DA in the DG was determined by in vivo microdialysis and HPLC,and the expression of D1 receptors was measured by immunehisto-chemistry.Results The DA content in the DG of the rats in VD group was lower than that in sham-operation group (P <0.05).The number of D1 receptor-positive cells in the DG hilus in VD group was increased compared with sham-operation group (P < 0.05),whereas the expression of D1 receptor in DG granule cell layer did not change (P > 0.05).Conclusion The DA content in the hippocampal DG is decreased in the VD rats,and its function may be compensated by the up-regulation of D1 receptors in the DG hilus.
