A new method for determining transaminase activity based on the color change of the reaction solution was established, by using alanine-dependent transaminase VfTA from Vibrio fluvialis JS17 as the research object coupled with pyruvate oxidase and horseradish peroxidase. After the optimization of the conditions, the linear relationship between VfTA activity units and the absorbance at 400 nm was investigated. This method was also applied to determine the activity of commercial transaminase ATA117. The results showed that the detection limit of transaminase VfTA activity was up to 0. 45 U/mL and the detection limit of ATA117 activity was up to 0. 5 U/mL. The transaminase activity could be quickly judged according to the color depth of the reaction solution.

OBJECTIVETo observe the intervention effects of electroacupuncture at "Yishu" (EX-B 3) on rats with type-2 diabetes mellitus (T2DM), so as to provide experiment references for acupuncture to treat T2DM.

METHODSAmong seventy male Wistar clean-grade rats, 8 rats were randomly selected into a control group; the rest rats were made T2DM model. Fifty-two rats which were successfully made T2DM model, according to randomized block method, were divided into a model group (10 rats), a medication group (10 rats), an electroacupuncture at "Shenshu" (BL 23) group (11 rats), an electroacupuncture at "Pishu" (BL 20) group (10 rats) and an electroacupuncture at "Yishu" (EX-B 3) group (11 rats). Seven days after successful establishment of model, the rats in the model group were fixed in the self-made rat bag without receiving any treatment; the rats in the medication group, according to body mass (10 mL/kg), were treated with intragastric administration of glimepiride; the rats in all the electroacupuncture groups were treated with electroacupuncture at "Shenshu" (BL 23), "Pishu" (BL 20) and "Yishu" (EX-B 3), respectively. The continuous wave was selected with a frequency of 15 Hz and a current intensity of 4 to 6 mA. The treatment was given 20 min per treatment, once a day, 5 treatments per week for continuous 4 weeks. Before the establishment of model and continuous 4 weeks after the intervention, blood samples were collected from rats' caudal vein, and fasting blood glucose (FBG) was measured with FBG device each week. After the last intervention, the rats were killed and hypothalamus, pituitary and adrenal gland were collected. The colorimetric method was applied to measure the contents of triglyceride (TG), cholesterol (TC), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C); radioimmunoassay was used to test the contents of glycated serum protein (GSP), fasting insulin (FINS), corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and cortin (CORT).

RESULTSFour weeks after the intervention, except that the rat's body mass in the normal group continued to increase, body mass in the model group, medication group and each electroacupuncture group were significantly reduced (P<0.01, P<0.05). Compared with the model group, the FBG in the electroacupuncture at "Pishu" (BL 20) group and electroacupuncture at "Yishu" (EX-B 3) group were obviously reduced (P<0.05, P<0.01); FBG in the electroacupuncture at "Yishu" (EX-B 3) group was lower than that in the medication group and electroacupuncture at "Shenshu" (BL 23) group (both P<0.05). The contents of TG, HDL-C and LDL-C in the electroacupuncture at "Yishu" (EX-B 3) group were reduced (P<0.05, P<0.01), the content of TG was significantly lower than that in the medication group and electroacupuncture at "Shenshu" (BL 23) group (both P<0.05), the content of LDL-C was significantly lower than that in electroacupuncture at "Shenshu" (BL 23) group (P<0.05). Insulin sensitivity index (ISI) in the medication group, electroacupuncture at "Pishu" (BL 20) group and electroacupuncture at "Yishu (EX-B 3)" group were evidently increased (P<0.05, P<0.01); ISI in the medication group was lower than that in the electroacupuncture at "Yishu" (EX-B 3) group (P<0.05). The content of CRH in the electroacupuncture at "Yishu" (EX-B 3) group was lower than that in the medication group and electroacupuncture at "Shenshu" (BL 23) group (P<0.05, P<0.01); the content of CORT in the electroacupuncture at "Yishu" (EX-B 3) group was lower than that in the medication group and electroacupuncture at "Pishu" (BL 20) group (both P<0.05).

CONCLUSIONElectroacupuncture at "Yishu" (EX-B 3) could reduce the level of CORT to improve the insulin resistance in rats with T2DM, improve insulin sensitivity index, regulate blood lipid metabolism and relieve the hyperactivity of the HPA axis.

Cellular fibronectin (cFn) is a type of bioactive non-collagen glycoprotein regarded as the main substance used to maintain periodontal attachment. The content of cFn in some specific sites can reflect the progress of periodontitis or peri-implantitis. This study aims to evaluate the expression of cFn messenger RNA (mRNA) in tissues of adult periodontitis and peri-implantitis by real-time fluorescent quantitative polymerase chain reaction (PCR) and to determine its clinical significance. A total of 30 patients were divided into three groups of 10: healthy, adult periodontitis and peri-implantitis. Periodontal tissue biopsies (1 mm×1 mm×1 mm) from each patient were frozen in liquid nitrogen. Total RNA was extracted from these tissues, and the content, purity and integrity were detected. Specific primers were designed according to the sequence, and the mRNA expression levels of cellular fibronectin were detected by real-time PCR. The purity and integrity of the extracted total RNA were both high, and the specificity of amplified genes was very high with no other pollution. The mRNA expression of cFn in the adult periodontitis group (1.526±0.441) was lower than that in the healthy group (3.253±0.736). However, the mRNA expression of cFn in the peri-implantitis group (3.965±0.537) was significantly higher than that in the healthy group. The difference revealed that although both processes were destructive inflammatory reactions in the periodontium, the pathomechanisms were different and the variation started from the transcription level of the cFn gene.
