Limb-shaking transient ischemic attack (TIA), a rare manifestation, is commonly caused by severe stenosis or occlusion of an extracranial internal carotid artery. Such patients are usually treated with surgical revascularization or anti-platelet therapy. We present a 56-year-old woman with 6 months’ episodic attacks starting with mouth skewed to the right and a sensation of ‘weakness’ involving predominantly her left arm, and at times, also involved the left leg. This was immediately followed by rhythmic jerky movements of the left arm and at times, also involved the left leg. Magnetic resonance angiography revealed severe stenosis of M1 segment of the right middle cerebral artery. The patient’s symptoms were signifi cantly improved by treatment with anti-platelet drugs and nimodipine.

The acute and chronic respiratory tract inflammation models were made to investigate the effect and mechanism of sterol extracts from Begonia Sinensis Rhizome (BSR). The first model of acute lung injury was made with Kunming mice by inhaling cigarette smoke, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, TNF-alpha/MPO were detected by Elisa, and cPLA2 protein were, detected by Western blotting respectively. Results showed that in model group, lung sheet became real, alveolar space shrank or disappeared, alveolar septum was thickened, plenty of inflammatory cells were infiltrated, capillary blood vessels were congestive and the expression of TNF-α, MPO, cPLA2 increased; after administration, a small amount of inflammatory cells were infiltrated, alveolar septum became obvious, capillary congestion status was significantly relieved and the expression of TNF-α, MPO, cPLA2 decreased (P < 0.05). The second model of chronic respiratory tract inflammation in BALB/c mice with bronchial asthma was induced by OVA, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, indexes such as IL-4, IL-5, IL-13 were detected by Elisa, and the cPLA2 protein expression was detected by Western blotting respectively. Results showed that in model group, a lot of inflammatory cells around lung vessels and bronchi exuded, bronchial goblet cells proliferated and the expression of IL-4, IL-5, IL-13, cPLA2 increased; after administration, inflammatory and goblet cell hyperplasia reduced, the expression of IL-4, IL-5, IL-13, cPLA2 also decreased (P < 0.05). The above results showed BSR sterol extracts could resist against respiratory inflammation by inhibiting cPLA2 in a dose-dependent manner.

Objective To discuss the clinical characteristics and therapeutic strategy of contrecoup contusion and laceration in frontal lobe. Methods 48 cases with contrecoup contusion and laceration in frontal lobe were analysed retrospectively with their imaging feature. Results In accordance with the GOS,36 cases survived well, 8 suffered from moderate disability. One keept in persistent vegetative state and one was dead. Conclusion Contrecoup contusion and laceration in frontal lobe merged with occipital extradural hematoma and diffuse brain swelling. Early diagnosis and treatment for the delayed occipital extradural hematoma, and standard large trauma craniotomy in treatment of heavy contrecoup contusion and laceration with diffuse brain swelling in frontal lobe were the key measures to improve the rate of success rescue.

Objective To investigate the role of mitochondrial KATP channel in the mechanism of the protective effect of ischemic preconditioning (IP) against ischemia-reperfusion (I/R) injury.Methods Forty-eight Wistar rats of both sexs weighing 250-350 g were used in this study. Forty rats were randomly divided into 5 groups ( n = 8 each): group A I/R; group B IP+ I/R; group C diazoxide (DZ mito-KATP channel activator) + I/R; group D 5-HD (mito-KATP channel blocker) + IP + I/R and group E 5-HD + DZ + I/R. Another 8 animals were used for electron microscopic examination of normal mitochondria as control. The animals were anesthetized with intraperitoneal pentobarbital 30 mg?kg-1. The hearts were immediately excised and passively perfused in a Langendorff apparatus with K-H solution at 5.8 kPa perfusion pressure and 36.5-37.5℃ via aortic cannulation. A fluid-filled latex balloon was via left atrium in left ventricle for the measurement of left ventricular function. I/R was induced after 30 min stabilization by clamping aortic cannula for 40 min followed by 30 min reperfusion. In group B and D the isolated hearts underwent 2 episodes of 5 min ischemia followed by 5 min reperfusion before I/R. In group C and E DZ 50 ?mol?L-1 was infused for 10 min and in group D and E 5-HD 100 ?mol?L-1 was infused for 10 min before I/R. HR, LVSP, LVEDP and coronary flow (CF) were measured at the end of stabilization (T0 , baseline), immediately before I/R (T1 ) and at 10, 20 and 30 min of reperfusion (T2.3.4.), and left ventricular developed pressure (LVDP= LVSP- LVEDP) was calculated. Myocardial tissue was obtained at the end of 30 min reperfusion for electron microscopic examination of mitochondria. Mitochondrial ultrastructure was assessed by Flameng scoring system (0 = normal, 4 = severely damaged) .Results Ischemic and DZ preconditioning significantly increased LVDP and decreased LVEDP and Flameng score. 5-HD pretreatment partly antagonized the protective effect of IP and completely antagonized that of DZ against I/R injury. Conclusion Ischemic preconditioning protects the heart against I/R injury mainly by activating mitochondrial KATP channel.

Objective To investigate the effect of ischemic preconditioning (IPC) on coronary microcirculation function in short-term hibernating myocardium(SHM) animal model.Methods Twelve little domestic Chinese pigs were established as the model of SHM by interventional method (closed-chest) and divided into 2 groups at random: the control group (CON group, n =6) and ischemic preconditioning group (IPC group, n =6).IPC was elicited by 2 cycle of 5 min of ischemia followed by 5 min of reperfusion before the establishment of model.Intracoronary Doppler guidewire was used to measure average peak velocity (APV),diastolic systolic velocity ratio(DSVR) and coronary flow reserve(CFR) of the distal to the stenosis at the baseline and 10 min,30 min,60 min,120 min after the establishment of model.Results APV,DSVR and CFR all decreased significantly in SHM model in both groups( P 0.05 ),at 60 min CFR of the CON group decreased significantly than before( 0.96 ? 0.27 vs 1.74 ? 0.49 , P 0.05 ).Conclusions The coronary microcirculation dysfunction happened at the time point of 60 min after coronary stenosis in SHM model,IPC can protect the coronary microcirculation function in SHM model.
