Objective:To develop a quantitative HPLC method for the analysis of eight impurities in active pharmaceutical ingredi-ent (API) asenapine maleate. Methods:The substances were analyzed using an Inertsil ODS-3 C18 column (250 mm × 4. 6 mm, 5μm), and gradiently eluted by the mobile phase A of 0. 1% aqueous trifluoroacetic acid and mobile phase B of acetonitrile in a flow rate of 1. 0 ml·min-1 with the detection wavelength of 220 nm and the column temperature of 35℃. Results:Asenapine was separa-ted completely from the impurities. The calibration curve of asenapine was linear within the range of 0. 45-1 458 μg · ml-1 ( r =1. 000 0), and that the impurities was linear within the range of 0. 4-30. 0μg·ml-1(r>0. 999). The mean recovery of the impurities was 93. 1%-106. 7%(n=9). Conclusion:The method is simple,sensitive and reproducible with good specificity and reliability,which can be used in the quality control of asenapine maleate.

Objective: Fungal keratitis is one of the most common diseases leading to blindness.It has a high incidence in China,and its early diagnosis and treatment are of vital importance.We aimed to investigate the value of laser confocal corneal microscopy in the clinical diagnosis of fungal keratitis.Methods: We conducted laser confocal corneal microscopy on 37 patients suspected of fungal keratitis,and compared the results with those obtained from the corneal tissue smears and fungal cultivation.Results: The fungus-infected corneas histologically exhibited defected epithelial cells,damaged subepithelial nerves and disordered stroma with reduced transparence.The hyphae showed bright,disordered,interlaced thread-or short rod-like structures.The positive rates of smear examination,fungus cultivation and laser confocal corneal microscopy were 48.65,62.16 and 78.39% for the 37 eyes,75.00,87.50 and100% for the 16 untreated eyes,and 28.57,42.85 and 61.90% for the other 21 pretreated eyes.Conclusion: Confocal laser corneal microscopy,rapid,effective and noninvasive,can be used as an important new alternative in the diagnosis of fungal keratitis

The secretion and localization of epididymal specific proteins ESP-1, ESP-2 were systematically studied by the PAGE-western blot and ABC immunocytochemical technique in the epididymis of the rabbit. The results indicated that ESP-1 and ESP-2 represented the rabbit epididymal specific proteins of 42 kd and 20 kd, respectively. They were immunoeytochemically negative in the testis, heart, liver, spleen, lung, kidney and skeletal muscle of the rabbit as well as testis and epididymis of the rat. However, in the rabbit epididymis, except the initial segment ESP-1 and ESP-2 were started to be positive from caput segment. The ESP-1 was displyed in the supranuclear area of the principle cells, while the ESP-2 was distributed evenly in the whole cytoplasm of it. Subsequently, the most heavy positive reaction was demonstrated in the corpus epididymis and the proximal segment of cauda. In contrast of the caput, the stereocilia of principle cells and lumen sperms of the cauda epididymis were positive also. However, in the distal segment of cauda the positive reaction in cytoplasm of principle cells was gradually decreased and became disappeared completely soon, while the stereocilia of it still remained heavy positive even in that of vas deferens. The epithelium of prostate gland and seminal vesicle were negative. These results indicated that both ESP-1 and ESP-2 were secretory proteins produced mainly in the principle cells of the corpus epididymis. After releasing into the lumen, they took part of epididymal fluid and might bind on the sperm to regulate sperm maturation. The possible physiological significance of ESP-1 and ESP-2 was discussed.
