Most pelvic fractures were commonly seen in polytrauma caused by violent forces,and often complicated with hemorrhagic shock,with mortality being 25%～39%.Anti-shock and control of bleeding are th e philosophy of treatment of this critical condition.Since 1985,hundred s of pelvic fracture victims have bee n sal-vaged in my hospital by VIP procedure which means ventilation(V),infusion(I),and pulsation(P).First,V was to establish an airway,then I was to manage hypovolumic shock,and fin ally,P was to improve the impaired heart function to maintain normal hemodynamics and tissue perfusion.It was necessary for antishock therapy to infuse rapidly and sufficiently in o rder to gain diluted blood.Pneumatic antishock garment,angiography an d em-bolism,and retroperitoneal tampon aded bleeding could control most hem orrhage associated with pelvic fractures.[

Objective To evaluate the radiofrequency catheter ablation for type I atrial flutter through application of Holo catheter labelling with anatomic imaging localization to ablate the isthmus of IVC TA during complete double way block.Methods Eleven cases with type I atrial flutter undergone Holo catheter labelling technique and consecution with conduction time change of coronary venous sinus orifice withright atrial lower lateral wall pace excitation ,were performed with radiofrequency catheter ablation for the isthmus outcoming with complete double way conduction block. Results All together 11 cases with 4 of atrial flutter and 7 of sinus rhythm were undergone radiofrequency catheter ablation resulting with double way conduction block of the isthmus accompanied by prolongation of right atrial conduction time 56.0?2.3ms and 53.0?4.6ms respectively.The right atrial excitation consecution during coronary venous sinus orifice and right atrial lower lateral wall pace excitation appeared to be in clockwise and counter clockwise of single direction. No recurrence occurred during 3-34 months follow up with only one showing atrial fibrollation.Conclusions The application of Holo catheter labelling technique with anatomic imaging localization to achrieve the double way conduction block by radiofrequency catheter ablation of TVC TA isthmus, is a reliable method for treating atrial flutter.

Next generation sequencing (NGS),also known as massively parallel sequencing (MPS),with significant advantages such as high throughput,rapidness,integration and low cost,has been widely used in research and clinical diagnosis fields and promises bright future for forensic applications.Compared with traditional DNA sequencing methods,NGS technologies allow the simultaneous detection of various forensic genetic markers.The classical CE-based STR genotyping method only can differentiate alleles with length polymorphism.However,there are occasions like DNA base substitution and repeat sequence variations,which give different alleles with the same size of amplicons.These alleles are heritable from parents to off-springs,and could be of great importance for solving criminal cases.NGS-based STR genotyping can be compatible with current STR data output mode,and allows for the full resolution of STR loci by providing additional sequencing polymorphism information.In this article,the authors focused on the forensic STR genetic markers and next generation sequencing,and reviewed recent progresses on NGS-based STR genotyping.Perspectives of NGS-based full resolution STR genotyping were presented and possible challenges were discussed in the hope of providing a reference for related studies and applications.

Objective To investigate the efficacy of the enhancement treatment on osteoporotic vertebral compression fracture and its complications in the elderly.Methods From September 2007 to February 2012,183 patients with osteoporotic vertebral compression fracture underwent percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) in our department.157 of them were completely followed up (PKP group,n=96; PVP group,n=61) and totally 182 vertebral bodies were fractured (PKP group,n=107; PVP group,n=75).Visual analogue scale (VAS) score and Oswestry disability index (ODI) score were evaluated before and 3 days and 3 months after the surgery.Plain film radiography was taken to evaluate the vertebral body height.ODI score was evaluated at the end of the follow-up.The leakage of polymethylmethacrylate (PMMA) during the operation and the refracture were recorded.Results The mean height of the vertebral body before operation had no difference between PVP and PKP group [(1.31±0.18) cm vs.(1.32±0.16) cm,t =0.72,P＞0.05].After the operation,the mean height of the vertebral body was lower in PVP group than in PKP group [(1.50±0.20) cm vs.(1.66±0.17) cm,t=2.28,P＜0.05].The mean amount of the PMMA injected into the vertebral bodies was less in PVP group than in PKP group [(2.93±0.34) ml vs.(3.34±0.49) ml,t=2.39,P＜0.05].In the PVP group,the VAS scores were (7.5±0.79),(3.0±0.6) and (1.9±0.9) before,3 days and 3 months after operation respectively,and there was a significant difference in VAS score before versus 3 days after operation (t =15.59,P＜0.05).In thePKPgroup,the VAS scores were (7.3±1.0),(3.0±0.8) and (2.2± 0.9)before,3 days and 3 months after operation respectively,and there was a significant difference in VAS score before versus 3 days after operation (t=10.69,P＜0.05).In the PVP group,the ODI scores were (78.9±7.3),(30.0±3.7) and (25.5±3.5) before and 3 months after operation and at the end of follow-up respectively,and there were significant differences in ODI score before operation versus 3 months after operation (t=20.83,P＜0.01) and 3 months after operation versus at the end of follow-up (t=4.03,P＜0.05).In the PKP group,the ODI scores were (78.8±6.8),(29.8±4.43) and (23.8 ± 2.7) before operation,3 months after operation and at the end of follow-up respectively,and there were significant differences in ODI score before operation versus 3 months after operation (t=21.52,P＜0.01) and 3 months after operation versus at the end of follow-up (t=3.14,P＜0.05).There were no significant differences in VAS and ODI scores between the two groups before versus after operation (t=0.34,P＞0.05).The incidence of refracture was 8.2％ in PVP group and 9.4％ in PKP group,which had no statistical difference between the two groups(x2 =0.06,P＞0.05).All the leakage was asymptomatic.The incidence of PMMA leakage was 20.0％ (15 cases) in PVP group and 9.3％ (10 cases) in PKP group,which had a statistical difference between the two groups (x2 =4.22,P ＜ 0.05).Conclusions Enhancement treatment for osteoporotic vertebral compression fracture can quickly relieve the pain and improve the quality of life.PKP and PVP show no differences in the effect of analgesia and the improvement of life quality,but PKP has the advantages in recovering vertebral height and reducing PMMA leakage.

A method of LC-QTOF/MS combining with chemical synthesis has been used to determine the structures of three novel bile acids from bear bile powder. Reference substances of tauroursodeoxycholic acid and taurochenodeoxycholic acid were oxidized by pyridinium chlorochromate. The products were analyzed by LC-QTOF/MS. Total 4 products including 3 isomers were predicted and identified according to the PCC oxidation theory and LC-QTOF/MS results. Bear bile powder samples were dissolved by methanol and analyzed by LC-QTOF/MS. Three unknown peaks were found and identified as 2-[[(3beta, 5beta)-3-hydroxy-7, 24-dioxocholan-24-yl]amino]-ethanesulfonic acid, 2-[[(5beta)-3, 7, 24-trioxocholan-24-yl]amino]-ethanesulfonic acid and 2-[[(5beta, 7beta)-7-hydroxy-3, 24-dioxocholan-24-yl]amino]-ethanesulfonic acid, separately, by matching their results with that of oxidation products above.
