Objective To investigate the expression of glucose transporter 3(GLUT 3) transcription level at different ischemic time in rats' focal cerebral ischemic penumbra and core of cortices.Methods Focal ischemic models of middle cerebral artery occlusion (MCAO) in rats were made by inserting nylon surgical thread. Brain samples were harvested from ischemic penumbra and core of cortices. The change of GLUT 3 mRNA was assessed by RT PCR.Results GLUT 3 mRNA in the penumbra regions slightly increased at 3 h after ischemia, and reached a peak at 24 h, in 96h following ischemia it came back to the normal level. As for ischemic core regions, GLUT 3 mRNA had a short time increase at 3 h after ischemia, and then rapidly decrease to the low level. Conclusion GLUT 3 mRNA expression was notably up regulated in the penumbra regions after focal cerebral ischemia,it may be a protective reaction against ischemic injury.

Hepatocyte growth factor ( HGF),a multifunctional cytokine,plays a biological role through acting on the cell surface transmembrane receptor c-Met.The growth,invasion and metastasis of many tumors are associated with the abnormalities of HGF-c-Met signaling pathway.Studies found that HGF and its receptor c-Met have close relations with the occurrence,metastasis,invasion and prognosis of multiple myeloma.

The apoptosis was observed under a fluoroscope when the tested tumor cells were treated with the supernatant derived from the liquid culture of an actinomyces strain AK 11, which had showed cell toxicity by means of MTT assay, and was further confirmed by the correspondent band of ”DNA ladder” in the agarose gel electrophoresis. In a bioassay employed nude mouse, the pure compound produced by the strain AK 11 showed tumor inhibition in rates of 52.01% and 33.64% corresponding to the dosages of 0.016 ?g?kg -1 and 0.008 ?g?kg -1 ip, respectively. According to the indexes IC 50 of human hepatocarcinoma SMMC7721 and stomach cancer MGC 803 cells, it was estimated that the inhibition effect of the pure compound was slightly stronger than that of Adriamycin. The results showed high antitumor effect of the tested compound from the strain AK 11. When the cells were treated with AK 11, it was found by flow cytometry analysis that cell division was ceased at S phase due to the DNA synthesis block .

Objective To explore the association of expression between the longevity gene SIRT1 and the forkhead transcription factor FOXO1 in the beta cell of islet in rat,and provide the basic prevention and cure rationale for the type 2 diabetes mellitus.Methods Eleven male SD rats of 18 months old were randomized into two groups:6 in calorie restriction(CR)group and 5 in the control group.After 6 months' breeding,the caudal end of islet was collected.The expression and location of SIRT1,FOXO1 and insulin were detected by immunohistochemistry;sections of pancreas were stained for senescence-associated ?-galactosidase(SA-?-Gal)to identify cell senescence of pancreatic islets.Results SIRT1 and FOXO1 were expressed in both the kytoplasm and nucleus,while insulin and ?-Gal were located in the kytoplasm.Compared with the control group rats,there was higher SIRT1 expression(P0.05)expression was detected in the beta cells of CR group rats.The lower positive rate of FOXO1 located in the nucleus the higher expression of SIRT1 in the rat beta cell of islet.Conclusion Calorie restriction could induce the high expression of SIRT1 in the rat beta cell of islet,and we think SIRT1 may delay the senescence process of rat beta cell through the repression of transcription factor FOXO1;it's beneficial to the prevention and cure for type 2 diabetes mellitus.

Objective To investigate neurological recovery effect and mechanisms of blood activating and phlegm removing decoction in the treatment of patients with hypertensive cerebral hemorrhage.Methods 68 patients with hypertensive cerebral hemorrhage in our hospital were divided into two groups.34 patients of the control group were given conventional western medicine,and 34 patients of the observation group were taken conventional western medicine combined with blood activating and phlegm removing decoction.The clinical outcomes, hematoma volume change and neurological recovery were compared,and analyzed its mechanism of action.Results The effective rate of the observation group(94.12%) was significantly higher than 73.53%of the control group (χ2 =5.31,P<0.05). After 7d,14d,21d treatment,NIHSS scores of the observation group [(12.87 ±1.43) points,(8.55 ±1.11) points and (5.67 ±0.76) points] were significantly lower than those of the control group [(20.43 ±2.57) points, (17.66 ±2.08)points,(14.54 ±1.44)points],and the differences were statistically significant (t=14.99,22.53, 31.76,all P<0.05).After treatment,hematoma volume of the observation group[(6.44 ±0.54)mL]was significant-ly lower than before treatment[(16.30 ±1.90)mL]and after treatment in the control group [(12.11 ±1.44)mL] (t=29.11,21.50,all P<0.05).After treatment,ALD score of the observation group [(66.34 ±5.22)points] was significantly lower than before treatment[(27.53 ±2.20)points]and after treatment in the control group[(47.55 ± 3.33)points],and the differences were statistically significant(t=39.95,17.70,all P<0.05).Conclusion The effect of blood activating and phlegm removing decoction in the treatment of patients with hypertensive cerebral hemor-rhage is significant,can significantly improve neurologic impairment and daily living skills,has no obvious conflict of interest and high application value,worthy of promotion and application.

AIM:To establish the quality standard for Pheretima Dispensing Granules.METHODS:Pheretima Dispensing Granules were identified by TLC.The content of hypoxanthine in Pheretima Dispensing Granules was determined by HPLC,and succinic acid by high performance capillary electrophoresis HPCE.RESULTS:Spots obtained from the test solutions had the same color as amino acid reference solution,Pheretima reference substance and the blank solution had no interference.The contents of hypoxanthine were in the range of 1.6 mg/bag-3.3 mg/bag and succinic acid 23.58 mg/bag-35.38 mg/bag in Pheretima Dispensing Granules,respectively.CONCLUSION:The methods of identification and quantification were accurate,realizable and reproducible.It can be used effectively for the quality control for Dispensing Granules.

ZJ-XD-I multifunctional internal sterilization machine for medical instrumentation is applied in medical instrumentations with circulatory loop such as anesthetic machine and respirator. The machine can generate ozone and hydrogen peroxide, and then the two gases are mixed and introduced into the internal loop to eliminate adnexed hydrogen peroxide such as the virus and germ, and thus the nosocomial infection due to repeated uses of medical instrumentations. The machine is composed of the gas compression component, atomization unit, gas extraction component, control circuit and the filtrating unit.

Emodin is one of the main active ingredient of Rheum palmatum, and has anti-inflammatory, anti-bacterial, anti-viral and other effects. In recent years, it arouse concern since it has a significant anti-tumor effect with low toxicity. In this paper we mainly report the anti-cancer effects of emodin according to the studies of the past five years, including four parts such as inhibit tumor growth, inhibit migration and invasion, enhance the efficacy of combination therapy, increase chemosensitivity and attenuated side effects. We hope that our work may provide a reference for further study.
