ABSTRACT

Objective To study the action of puerarin on Caspase-3 and Bcl-2 expression of hippocampal CA1 neurons in ovariectomized rats, and explore its mechanism. Methods SD female rats were randomly assigned into sham operation group, model group, premarin group and puerarin groups (120, 60, 30 mg/kg). The model group and sham operation group were injected NS intraperitoneally, other groups were treated with corresping drugs for 30 d. Immunohistochemistry and RT-PCR were used to determine Caspase-3 and Bcl-2 expression of hippocampal CA1 neurons. Results Caspase-3 expression of hippocampal CA1 neurons was significantly decreased in high-dose puerarin group (P <0.05). Bcl-2 expression of hippocampal CA1 neurons was significantly increased in high- and medium-dose puerarin groups (P<0.05, P<0.01). Bcl-2 mRNA level of hippocampal CA1 neurons in high-dose puerarin group was significantly increased (P<0.05). Conclusion Puerarin can decrease Caspase-3expression and increase Bcl-2 expression of hippocampal CA1 neurons in ovariectomized rats, and has protective effect on neuronal structure.

ABSTRACT

Purpose To investigate the prognosis and influencing factor of hematoma complicated from ultrasonography-guided EnCor vacuum-assisted breast biopsy system in minimally invasive surgery for breast lesions, and to provide reference for clinical treatment. Materials and Methods 280 female patients with 486 benign breast lesions underwent minimally invasive excision using a ultrasonography-guided EnCor vacuum-assisted device, occurrence and the inlfuence factors of hematoma complicated from the operation was observed. Results All the 486 lesions were completely excised with EnCor system, hematoma (≥1cm) were found in 47 cases after 24 hours and almost disappeared in 6 months. After analysis of the occurrence of hematoma, it was found that the following situations would lead to a higher incidence of hematoma, which included lumps ≥ 2.5 cm, more than two lesions removed at one time, lumps locating deep inside the areola or the edge of breasts, bigger and less dense breasts, operation in menstrual period, pressure bandaging after operation less than 12 hours and operation without using adrenaline (P<0.05 or P<0.01). Conclusion Benign lesions breast can be effectively excised using ultrasonography-guided EnCor vacuum device, and the factors listed below could affect the occurance of hematoma complicated from the surgery, including the size, location and number of the resected nodules, breast shape, surgery during menstrual period, postoperative pressure bandaging and the use of hemostatics.

ABSTRACT

Objective To investigate the effects of puerarin on renal advanced glycosylation end products (AGEs), expression of transforming growth factor-?1 (TGF-?1) and pathomorphism in diabetic rats. Methods Rats were randomly divided into following groups:normal control rats (Group CN), diabetic rats (Group DM) and diabetic rats treated with puerarin (Group DP). After Puerarin was given to STZ-induced diabetic rats for 10 weeks, blood glucose, urine protein, glomerular basement membrance thickness (GBMT) and profile of kidney hypertrophy in diabetic rats were measured and analysed. The renal pathologic changes were observed by light microscopy and electron microscopy. Renal AGEs content was determined by expose time of fluorescence microscopy. The expression of TGF-?1 was examined by immunohistochemical methods. Results Urine protein, GBMT and profile of kidney hypertrophy were significantly increased in diabetic rats as compared with control animals (P
