Objective To observe the effects of hirudo capsules on degree of platelet activation and blood rheology in patients with cerebral arteriosclerosis. Methods 122 patients with cerebral arteriosclerosis were randomly divided into two groups by the random number table:observation group(61 cases)and control group (61 cases). The two groups received conventional treatment such as antihypertensive and hypoglycemic drugs,and 100 mg of aspirin once a day. In the observation group,additionally hirudo capsules 0.75 g,3 times a day were given. The therapeutic course in both groups was 2 months. Prior to the start of treatment and on the next day after the end of treatment,traditional Chinese medicine(TCM)clinical syndrome integral,platelet membrane glycoproteins caspase 1 (PAC-1),platelet adhesion molecule P selection(CD62P)positive rate,and blood rheology indexes were detected,in addition to the adverse reactions . Results Before treatment,there were no statistical significant differences between the two groups in terms of TCM clinical syndrome integral such as headache,dizziness,head fullness,multiple somnolence amnesia,lip dark purple,sublingual veins purple in color,PAC-1,CD62P positive rate,hemorheology indexes(all P>0.05). After treatment,TCM clinical syndrome integral PAC-1,CD62P,low shear viscosity,high shear viscosity,plasma viscosity and the hematocrit of two groups were significantly lower than those before treatment, the improvement in observation group being more remarkable〔headache:0.75±0.69 vs. 1.23±0.92,dizziness:0.96±0.78 vs. 1.54±1.24,head fullness:0.65±0.59 vs. 1.48±1.17,multiple somnolence amnesia:0.77±0.72 vs. 1.69±1.14,lip dark purple:0.83±0.81 vs. 1.32±0.79,sublingual veins purple:0.84±0.67 vs. 1.20±0.74, PAC-1:(10.31±4.57)%vs.(15.13±6.27)%,CD62P:(11.39±5.24)%vs.(16.40±7.91)%,low shear viscosity (mPa?s):7.52±3.37 vs. 8.97±3.50,high shear viscosity(mPa?s):4.35±1.12 vs. 5.58±1.19,plasma viscosity (mPa?s):1.54±0.35 vs. 1.88±0.42,hematocrit(HCT):0.43±0.09 vs. 0.49±0.10〕. In the patients' follow-up, there were no obvious side effects of hirudo capsules. Conclusion Hirudo capsule is a safe and effective drug for treatment of patients with cerebral arteriosclerosis as it is helpful in reducing platelet activation degree and improving the blood rheology indexes.

Objective To better understanding the clinical presentations of phaeohyphomycosis,and improve the diagnosis and management of the disease.Methods We reported a case of pulmonary phaeohyphomycosis caused by Exophiala jeanselmei at the First Affiliated Hospital of Guangzhou Medical University in 2008,and reviewed the relevant literature.The clinical,radio-logical and etiological features were summarized based on this case and the other 23 phaeohyphomycosis patients reported in China from January 1995 to August 2013.Results 24 Chinese cases of phaeohyphomycosis have been reported to date,including 15 males and 9 females.The age of these patients ranged from 4 to 76 (mean 40.0±21 .8)years old.Seventeen patients were otherwise healthy.The other 7 patients had complications.Clinical presentations of phaeohyphomycosis vary widely,including cutaneous and subcutaneous infection in 18 cases,pulmonary and central nervous system involvement in two cases each,para-nasal sinus and palpebral conjunctiva infection one case each.The diagnosis of 18 cases were confirmed both microbiologically and histologically.One case was confirmed histologically alone.Five cases were identified microbiologically alone.The samples for culture were collected from skin abscess (1/5 ),pulmonary tissue (2/5 ),and cervical spinal fluid (2/5 ),respectively. Twenty-two strains of causative organisms were identified,7 of which were Exophiala jeanselmei .Twenty-three patients received treatment.They were cured by antifungal agents alone (18)or in conjunction with surgical resection (4 ),or assisted with XD-635AB-based photodynamic laser therapy (1).Specifically,10 pa-tients were cured by itraconazole alone.Conclusions In China, most patients of phaeohyphomycosis have concurrent conditions or have previously received immunosuppressive agents and cor-ticosteroids.Cutaneous and subcutaneous infection were most common,located mainly on limbs,face,chest and abdominal skin.The most frequently isolated pathogen is Exophiala jeanselmei ,followed by Phialophora verrucosa and Exophiala spinifera .Itraconazole therapy would be very effective.Susceptibility testing is very useful in case of refractory infection.

Objective · To study the metabolite profiles on patients of ischemic stroke using metabonomics approach. Methods · The serum samples from the 29 patients with ischemic stroke and 31 healthy controls were analyzed by gas chromatography time-of-flight mass spectrometry (GC-TOFMS) coupled multi-dimensional statistical methods to find differential metabolites in two groups. Results · Orthogonal partial least squares analysis (OPLS) model was generated based on identified metabolites and shown clear discrimination from patients and healthy controls. Some serum metabolite levels were significantly altered in patients. Six up-regulated metabolites included γ- aminobutyric acid, glutaric acid, glyceric acid, gluconic acid, lactobionic acid, and cholesterol, and nineteen down-regulated metabolites included citric acid, aconitic acid, malic acid, succinic acid, β-alanine, and glycerol-3-phosphate. Conclusion · Amino acid metabolism, glycometabolism and tricarboxylic acid (TCA) cycle are disturbed in patient of ischemic stroke. The metabonomic approach has great potential to understand the underlying mechanisms of stroke in ischemic patients.
