This study investigated the inhibitory effect of grape seed proanthocyanidin extract (GSPE) on selenite-induced cataract formation in rats and the possible mechanism. Eighty 8-day-old Sprague-Dawley rats were divided randomly into 5 groups: control group, model group, three GSPE groups (low dose, medium dose and high dose). Control group received subcutaneous injection of physiological saline. Model group was given subcutaneous injection of sodium selenite (20 μmol/kg body weight) on the postpartum day 10, and once every other day for consecutive three times thereafter. GSPE treated groups were respectively administered GSPE at doses of 50, 100, and 200 mg/kg body weight intragastrically 2 days prior to the selenite injection (that was, on the postpartum day 8), and once daily for fourteen consecutive days thereafter. The opacity of lenses was observed, graded and photographed under the slit lamp microscopy and the maximal diameter of the nuclear cataract plaques was measured. The lenses were analyzed for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), calcium (Ca(2+)), nitric oxide (NO) and anti-hydroxyl radical ability (anti-OH(-)). The histomorphology of lenses was observed with HE staining under a light microscope. The levels of calpainII, and iNOS protein and mRNA expression in lenses were detected by using immunohistochemistry and real-time quantitative RT-PCR. The results showed subcutaneous injection of sodium selenite led to severe nuclear cataract in model group, and the achievement ratio of model group was 100%. As compared with model group, the degree of lenses opacity and the maximal diameter of nuclear cataract plaques were significantly reduced in GSPE-treated groups. Moreover, we observed selenite treatment caused a significant decrease in the activities of antioxidative enzymes (SOD, CAT, GSH-PX) and anti-OH(-) ability, accompanied by a significant increase in the levels of MDA, NO, Ca(2+) as well as iNOS, and calpainII protein and mRNA expression. Administration of GSPE could dose-dependently preserve the activities of these antioxidative enzymes and anti-OH(-) ability, accompanied by a significant reduction in the levels of MDA, NO, Ca(2+) as well as iNOS, and calpainII protein and mRNA expression. These results suggested that GSPE markedly prevented selenite-induced cataract formation probably by suppressing the generation of lipid peroxidation and free radicals as well as the activation of iNOS, and calpainII in the lenses.

Objectives To evaluate mini/VITAL and BacT/Alert, two fully automated blood culture systems. Methods Standard mini/VITAL AER and ANA bottles (bioM′erieux, Marcy 1′Etoile, France) and BacT/Alert FAN aerobic and FAN anerobic bottles (organon Netherlands) were used. The bottles were analysed over a period of 7 days. A total of 600 samples of blood, 108 samples of body fluid, and 100 strains of imitation were detected by mini/VITAL and BacT/Alert parallelly. The bottles of flagged positive were smeared and Gram stained before being examined under a microscope. Subcultures were performed in parallel on fresh blood agar and chocolate agar incubated in microaerophilic Conditions with 5% CO 2. All the bottles flagged negative were examined in the same conditions as the positive bottles. Results mini/VITAL: The positive rate for aerobic and anaerobic blood cultures was 10% and 5% respectively, for aerobic body fluid culture was 26 9%. No contaminants were detected. 0.5% false positive and 0.8% false negative were detected. 90% of positive sample were detected in 48 h. The shortest time of report of positive bottles was 1.5 h for blood culture. BacT/Alert: The rate of positive of aerobic and anaerobic blood culture was 9.8% and 5% respectively. The positive rate of body fluid culturs was 26.9%. There were used 3 bottles contaminated. The false positive and false negative rate were 0.5% and 0 98% respective. 95.5% of positive bottles were detected in 48 h. The shortest time of flagged positive was 2.5 h. Conclusion mini/VITAL and BacT/Alert were accurate automated blood culture systems for the detection of bacteremia. There was no significant difference on the speed of detection between BacT/Alert FAN bottles and mini/VITAL standard bottles.

OBJECTIVETo observe the effect of Yangfei Ziyin Decoction (YZD) on symptoms, serum levels of TNF-alpha, IL-6, and aquaporin-5 (AQP-5), and pathology of Sj6gren's syndrome (SS) model mice.

METHODSTotally 60 mice were divided into 6 groups according to random digit table, i.e., the model group, the normal control group, the high, medium, low dose YZD groups (administered with YZD at 36.7, 18.4, 9.2 g/kg, 0.2 mL/10 g), the Chinese patent medicine group [CPM, administered with total glucosides of paeony at 0.6 g/kg], 10 mice in each group. All intervention was performed for six successive days in a week, with an interval of one day, a total of 50 days. Body weight, salivary secretion, food and water intake were measured at day10, 20, 30, 40, and 50, respectively. At day 50 blood was collected. Submandibular gland, thymus, and spleen were weighed. Serum levels of TNF-alpha, IL-6, and AQP-5 were detected by ELISA. Pathological changes of submandibular gland were observed. Results Compared with the normal control group, there was no change in water intake of mice in the model group, but with reduced salivary secretion (P < 0.01, P < 0.05). Thymus/spleen/submandibular gland weight and index increased in the model group (P < 0.01, P < 0.05). Compared with the model group at the same time point, salivary secretion increased in the CPM group and 3 YZD groups (P < 0.01 , P < 0.05). Compared with the model group, thymus/spleen/submandibular gland weight and index decreased in the CPM group (P < 0.01, P < 0.05). Thymus/submandibular gland weight and index decreased in the low dose YZD group (P < 0.01, P < 0.05). Thymus/submandibular gland weight and index, and spleen index decreased in high and medium dose YZD groups (P < 0.01 , P < 0.05). Levels of TNF-alpha and IL-6 decreased, but AQP-5 level increased in the CPM group (P < 0.05). AQP-5 level increased in high and medium dose YZD groups (P < 0.01 , P < 0.05). In the model group alveoli and duct of salivary gland were destroyed, alveoli and duct were irregular, epithelial cells were degenerated, necrotic, and desquamated. Mild-to-moderate lymphocytic infiltration occurred around submandibular gland. Pathological changes were alleviated in the CPM group and 3 YZD groups.

CONCLUSIONYZD could improve clinical symptoms, serum levels of TNF-alpha, IL-6, AQP-5, and pathological changes of SS model mice.
