Introduction: Differences in systolic blood pressure reading between arms are common but could signal trouble if the discrepancy is significant. Early detection of aortic dissection could invariably determine patient’s survivability. Hence, a high index of suspicion with prompt diagnostic imaging is vital for accurate diagnosis. Case Presentation: A previously healthy 35-year-old lady was referred from district hospital for hypertensive cardiomyopathy complicated by acute pulmonary oedema. After being admitted to the Intensive Care Unit, the mean arterial pressure on the left arm was noted to be significant higher. On physical examination, both lower limbs were dusky in appearance because of poor perfusion. Investigations: Computed Tomography Angiography showed extensive arch and abdominal aorta dissection extending to the proximal common carotid artery. There was distal abdominal aorta thrombosis with partial left renal infarction. Echocardiogram showed global hypokinesia, presence of intimal flap, aortic regurgitation and mild pericardial effusion. Supine chest X-ray showed apparent cardiomegaly. Treatment: Repair of the ascending aortic dissection and suspension of the aortic valve by the cardiothoracic team on Day 2 of admission. The vascular team did bilateral high above knee amputation on Day 9 of admission. Outcome: Patient passed away on Day 10 of admission. Discussion: With the absence of classical features of aortic dissection, establishing the diagnosis can be challenging and requires both good clinical judgment and prompt radiological imaging, such that early treatment can be initiated. Conclusion: A high index of suspicion and good clinical judgment is needed in cases of significant blood pressure discrepancy between arms.

Objectlve To detect the KChIP2 mRNA level in rheumatic heart disease patients with or without atrial fibrillation (AF) by real-time PCR.Methods Right atrial appendage samples from rheumatic heart disease patients with (n=17) or without AF (n=13) were obtained during cardiac surgery.Total RNA was extracted from the atrial tissues.and the KChIP2 and Kv4.3 mRNA were detected by SYBR Green I real-time PCR with the GAPDH as the house keeping gene.Result The ratio of KChIP2/GAPDH(0.1468 ±0.0452 VS.0.2200±0.0388,P＜0.01)and the ratio of Kv4.3/GAPDH(0.3946±0.1826 vs.0.5257±0.1427.P＜0.05)were significantly lower in AF patients compared to non-AF patients.Conclusion Down-regulated atrial KChIP2 and Kv4.3 mRNA expressions in rheumatic heart disease patients with chronic AF might be one of the molecular bases responsible for the down-regulation of the Ito current density of AF.

To investigate the epidemiology of hand, foot, and mouth disease (HFMD) and the genetic characteristics of enterovirus A71 (EV-A71) in Linyi of Shandong Province, China during 2007-2012. The number of reported HFMD cases were obtained from the National Notifiable Disease Reporting System (NNDRS) were analyzed by descriptive epidemiology method; the VP1 region of EV-A71 isolated from HFMD patients in Linyi was amplified and sequenced. Finally, the genetic variability and phylogenecity of VP1 sequences of EV-A71 were analyzed by MEGA 5.0. The results showed that HFMD incidence was reported in each year from 2007 to 2012 in Linyi, and the highest incidence and mortality were reported in 2009, when there were total 14697 cases and 9 of death. The reported incidence was 140.28/100000, and the mortality was 0.086/100000. The peak incidence usually occurred between April and July, and the summit occurred in May. Scattered children accounted for 77.37%-92.00% of all cases. The peak age was 2.5 years during 2007-2009 and 1.5 years during 2010-2012. A total of 1365 laboratory-confirmed HFMD cases were reported in the 6 consecutive years, accounting for 2.98% of the gross number. Among these reports, the ratio of EV-A71 was 44.18%, and the ratio of coxsackievirus A16 (CVA16) was 46.59%. All EV-A71 strains isolated in Linyi during 2007-2012 belonged to the C4a evolutionary branch of C4 genotype. In conclusion, HFMD outbreaks occurred every year in Linyi during 2007-2012. Incidence varied significantly among different counties. The peak incidence in each year lasted from April to July. Most of the patients were children under 3 years of age, and scattered children took the highest proportion. Co-circulation of EV-A71 and CVA16 was the major cause of HFMD in each year. Since the first report of HFMD prevalence caused by EV-A71 (C4a) in 2007, the virus has been prevalent continuously in Linyi for 6 years.

The study purpose was to explore whether dichloromethylene diphosphonate (Cl(2)MDP)-loaded gelatin particles can induce the depletion of macrophage in reticuloendothelial system of liver and spleen or can depress the immunity of macrophage in SD rat models of immune thrombocytopenic purpura (ITP) to treat the ITP rats. New Zealand rabbits were immunized with platelets of SD rats to prepare rabbit anti-rat platelet serum, and the serum was intravenously injected into SD rats to produce the ITP model. In experimental ITP models, 150 microl of anti-platelet serum was intravenously injected into SD rats per 24 hours. The platelet counts maintained pathological level and were persistently less than 50 x 10(9)/L in the models during experiment process. The MTT test of macrophage RAW264.7 was carried out by means of Cl(2)MDP-loaded gelatin particles in vitro. After intravenous injection of a group dose of Cl(2)MDP-gelatin particles, the platelet counts of the rats were measured at the time of 4 hours, 24 hours, 48 hours, 72 hours and 96 hours, respectively, and bleeding times were detected in 24 hours. The results showed that Cl(2)MDP-loaded gelatin particles increased the platelet counts of ITP models to mean of 180 x 10(9)/L, a physiological level in 24 hours after injection, and kept this platelet level through whole process of 120 hours. Furthermore, rats pre-treated with Cl(2)MDP-loaded gelatin particles avoided the decrease of platelet counts significantly when they were injected anti-platelet serum. It is concluded that Cl(2)MDP-loaded gelatin particles restrain multiplication of macrophage RAW264.7, and promptly, effectively restore platelet counts of ITP models to physiological level in a dose dependent manner. So, the targeting therapy of drug-loaded gelatin particles offers a new idea and approach to treat ITP, and this strategy is worthy of further studies.
