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.[

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 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.

Objective To evaluate the microscopic characteristics of hepatocellular carcinoma (HCC) invasion,and to provide the reference for GTV-to-CTV expansion. Methods From January 2002 to January 2006,149 HCC patients treated by surgical resection were included. The pathologic slices and clinical data were reviewed, including the tumor size, capsule status, tumor edge, portal vein invasion, TNM stage, histology grade, serum alpha-fetoprotein (AFP), platelet count and the degree of liver cirrhosis. The distance between the tumor capsule and the invasion was measured by 2 senior pathologists. Results of the 149 patients evaluated,79(53.0%) patients presented micro-invasion ranged between 0.5-4.0 mm. The recurrence rate was higher in patients with micro-invasion than those without (44% vs 29%, P=0.047). The invasion extent was positively relative to the tumor size, capsule status, tumor edge, portal vein invasion, TNM stage,histology grade and AFP,while negatively relative to the platelet count. A score system was established according to five predictors of tumor size, capsule status, portal vein invasion, AFP and platelet count. The invasion distance below 2 mm was in 96.6% patients who had≤2 points and only 83.3% for those with 2 points. Conclusions For HCC patients,the invasion extent is relative to the tumor size,cap sule status,portal vein invasion, AFP and platelet count. These 5 predictors could be potentially used as a score system for GTV-to-CTV expansion.

Objective To evaluate the value of cholangiography for early diagnosis of ischemic-type biliary lasions(ITBL) after liver transplantation. Methods Two hundred and fifty-three patients with liver transplantaion between Jan 2004 and Oct 2006 were recruited. Initial cholangiography was compared with terminal cholangiography to evaluate the value of initial cholangiography of ITBL. The t test, Chi-square test, sum rank test were used for statistics. Results Based on initial cholangiography, 189 patients were diagnosed with normal appearance, while 64 patients were diagnosed with abnormal appearance. The abnormal initial cholangiography appearances included poor filling in 33 patients and irregularity in 31 patients. Based on terminal cholangiogruphy, 199 patients were diagnosed with normal appearance and 54 patients with ITBL In patients with abnormal initial cholangiography, ITBL was occurred in 39 of 64 patients including 10 of 33 poor frlling patients and 29 of 31 irregularity patients. In patients with normal initial appearance, ITBL was only occurred in 15 of 189 patients. The abnormal initial cholangiography was associated with ITBL significantly (X2 = 79.999, P = 0.000, r = 0.490). Initial cholangiography had an overall sensitivity of 72.22%, and specificity of 87.44%, with positive and negative predictive values of 60.94% and 92.06%, respectively. The abnormal initial cholangiogruphy was a risk factor of ITBL by logistic regression analyses(OR=15.193, P=0.000). Conclusion The abnormal initial cholangiography is associated with ITBL Initial cholangiography, especially minimal irregular of intrabepatic biliary tract, is a sensitive and specific method for the detection of ITBL after liver transplantation.

Objective:To investigate the diagnostic value of spiral CT head and neck angiography on carotid artery stenosis in patients with acute cerebral infarction.Methods:A total of 60 patients with acute cerebral infarction(ACI),who were treated in Affiliated Hospital of Yan'an University from January 2014 to January 2016,were selected as observation group,and 60 patients with non-acute cerebral infarction,as control group.The two groups of patients underwent spiral CT head and neck angiography.The degrees of carotid artery stenosis and the distribution of vascular plaques were compared between the two groups.The diagnostic value of spiral CT head and neck angiography in the diagnosis of carotid artery stenosis of the patients with ACI was evaluated.Results:The detection rates of mild and moderate stenosis in the observation group were significantly higher than those in the control group (P＜0.05),while the detection rates of severe stenosis and occlusion had no significant difference compared with the control group (P＞0.05).The total detection rate of stenosis in the observation group was higher than that in the control group (P＜0.05).There were plaques detected in the carotid bifurcation,common carotid artery,internal carotid artery and external carotid artery in the two groups.The total detection rate (69.4％) of the observation group was significantly higher than that (41.2％) of the control group (P＜0.05).Conclusion:Application of 128-slice spiral CT can effectively assess the head and neck angiography on carotid artery stenosis in patients with acute cerebral infarction.This method has a higher detection rate from mild to moderate stenosis and bilateral carotid artery plaques in the patients with ACI,and it has application value in the clinical diagnosis and prognosis.
