Objective To investigate the effect of propofol on expression of cyclinD1 and apoptosis in spinal cord neurons induced by ischemia-reperfusion (I/R) .Methods Sixty male Wistar rats weighing 200-250 g were randomly divided into 2 groups ( n = 30 each): group A I/R and group B propofol + I/R. The animals were anesthetized with 7% chloral hydrate 6 ml?kg-1. The abdomen was opened and the abdominal aorta was clamped distal to the left renal artery for 20 min. The aortic cross clamp was then released to allow reperfusion. In propofol group propofol 100 mg?kg-1 was administered intraperitoneally (IP) during the operation. Neurologic function was assessed using Taylor scale (0 = unable to move hind limbs, 4 = normal function) at 6 h after operation and on postoperative day 1, 2, 3, 7 (n = 6 at each time point) . The animals were killed after neurologic function evaluation and the spinal cord was removed for microscopic examination, detection of apoptosis in the spinal cord neurons ( TUNEL) and determination of cyclinD1 expression (immuno-histochemistry) . Results The histo-pathological damage to the neurons was significantly lighter, the neurological function better and the apoptotic index and the cyclinD1 expression were significantly lower in propofol group than in I/R group. Conclusion Propofol protects spinal cord against I/R injury by reducing neuronal apoptosis through down-regulation of cyclinD1 expression.

Objective To report a case of chromomycosis caused by Phialophora verrucosa and explore the laboratory features of the pathogen. Methods Skin lesion was examined by histopathology and fungus culture. The morphology of the isolate was observed by microscopy and scanning electron microscopy. The coenzyme Q system of this isolate was analyzed by HPLC assay. The DNA sequences of LSU rDNA D1/D2 region of this isolate and a standard fungus strain were compared. Results The initial lesion was an erythematous papule that subsequently developed into one or multiple coalescing warty papules or plaques slowly. The bronze-colored spores could were observed in the dermis or macrophages. The isolate grew very slowly, requiring 4 weeks of incubation. Microscopically, no characteristic structures were found on Sabourand′s dextrose agar, while there were vase-like structures, which were referred to as phialides on potato dextrose agar (PDA) and corn meal agar I (CMA-I). The phialides on PDA mostly grew at the top of hypha, but on CMA-I they mostly grew on the side of hypha. The isolate contained coenzyme Q-10, and its DNA sequence of LSU rDNA D1/D2 region completely consistent with those of the standard strain. Conclusion Chromomycosis caused by Phialophora verrucosa is rare in China. It can be diagnosed by fungus culture and histopathological examination. Coenzyme Q system analysis and DNA sequencing can exclude the interference from different phenotypes.

Objective To analyze the incidence of the disease, clinical features, diagnostic criteria, therapy and prognosis of Penicilliosis marneffei found in Guangdong province. Methods To analyze patients data, clinical features, laboratory findings, response to therapy, and prognosis of 15 cases Penicilliosis marneffei found in Guangdong province of China. Results The male was predominant compared with the female (ratio 2 to 1) and without occupational preference, but the patients with AIDS as underlying disease were mostly drivers and the unemployed. Thirteen patients were immunocompromised such as AIDS, connective tissue disease, and kidney transplant. Clinical features showed different manifestations, such as high fever, loss of weight, skin lesion, and respiratory system symptoms. Biopsy of the skin lesion showed PAS stain positive yeast-like, or sausage-form spores. Four patients were localized infection of the skin, eleven patients were systemic infection. Nine patients died, five recovered, 1 patient refused to be treated. Fifteen isolates from different anatomic sites of the patients were identified to be Penicillium marneffei by morphology and dimorphism in the culture, and eleven isolates among these 15 isolates were also confirmed by DNA sequence analysis. Conclusion The incidence rate of Penicilliosis marneffei become higher in the recent years and many patients were accompanied with AIDS in Guangdong province. Attention should be paid to the disease.

Kawasaki disease is far more frequent in children than in adults. The pathogenesis of Kawasaki disease is unknown, but it involves changes to the coronary artery and other diverse clinical manifestations. There are currently no specific laboratory diagnostic indexes, and especially since the disease is rare in adults, so it is extremely easy to misdiagnose or to overlook entirely. Our retrospective analysis of an diagnosis of and treatment for Kawasaki disease in an adult provides a guide to clinical doctors in terms of understanding Kawasaki disease, early diagnosis of it, and improved prognosis.

We report a case of cutaneous and subcutaneous phaeohyphomycosis caused by Exophiala jeanselmei after renal transplantation in Guangdong. A 66-year-old man who had a renal transplantation 6 years ago was admitted in October 2011 for the presence of 16 nodules (0.5-1.5 cm) found on his right middle finger, wrist and forearm for 5 months. Microscopic examination of the purulent exudate showed segmented and branched brown mycelium, and tissue biopsy and PAS staining showed fungal hyphae. The isolate was processed for morphological identification and molecular sequence analysis. A black colony was found after culture of the isolate on SDA at 26 degrees Celsius;, and small culture identified the isolate as Exophiala jeanselmei. ITS sequence analysis of the isolate showed a 100% homology with Exophiala jeanselmei. E-test strip was used in drug sensitivity test, and the isolate was sensitive to amphotericin B, voriconazole, itraconazole and fluconazole, but resistant to 5-flucytosine and caspofungin. Good response was obtained with surgical intervention, local injection and systemic antifungal treatment.
