Rice straw degradation with white rot fungi and cellulose multienzyme was studied. The results indicated that the LiP, MnP activity produced by P. chrysosoporium 172 could reach 28.3U/g and 12.6U/g respectively under suitable culture condition. And the lignin was degraded efficiently in contrast with the cellulose and hemicellulose in rice straw solid fermentation. Following treatment with white rot fungi, using multienzyme produced by A. niger NL-1 could greatly accelerate the decomposition of rice straw. The decomposition rate of cellulose, hemicellulose, lignin and the loss rate of dry material were 53.8%,57.8%,44.5% and 46.3% respectivity when hydrolysis rice straw 48h with cellulase multienzyme (including 3 IU /g rice straw) after culture P. chrysosoporium 172 for 10 days. Scanning electron microscope analysis showed the cell wall of rice straw was destroyed severely, and the whole tissue got loosely. These results demonstrated the rice straw had been decomposed efficiently and completely.

Metabolic abnormalities were identified and carotid intima-media-thickness(IMT)was measured in 221 individuals at risk for metabolic syndrome(MS).The results indicated that IMT was significantly thicker in MS individuals than that in non-MS individuals(P＜0.01).And there was a tendency of progressive increase in IMT with increasing components of metabolic syndrome.

Objective To investigate the expression of aquaporin-5(AQP5) in lipo-polysaccharide(LPS)-cigarette smoking inducible SD rats,and the effect of ambroxol chloride(AMB)on its expression. Methods Twenty-one SD rats were randomly divided into three groups: AMB intervention group,model group(LPS-cigarette smoking induction group) and control group.TNF-? was determined from lung homogenate supernatant,bronchial alveolar lavage fluid(BALF) and serum by ELISA.The semi-quantitation of AQP5 transcription and expression were measured by in situ hybridization and immunohistochemistry,respectively. Results TNF-? from lung homogenate supernatant and BALF in model group was more than AMB intervention group and control group(P

Objective To observe the status of oxidative stress and activity of alkaline phosphatase(ALP) in rats exposed to high fluoride for the different periods and to analyze the effect of fluoride on the activity of ALP and oxidative stress in fluorosis rats. Methods Twenty-four Wistar rats were divided into control and high-fluoride groups according to their body mass, 12 rats in each group. The control group drank tap water(sodium fluoride concentrations < 1 mg/L), and high-fluoride group drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L). On a standard diet and water available ad hbitum, each rat was measured body weight once a week in 1,4,8,12 week. The biochemical techniques were used to test the indicators of oxidative stress including malonaldehyde(MDA), superoxidedismutase(SOD), glutathione peroxidase(GPx), uric acid and activity of ALP in serum of fluorosis rats. Results There was a interaction between fluoride and time in the activity of ALP (F = 4.690,P < 0.05). The activity of ALP was obviously higher in rats exposed to fluoride for 1,12 week [ (19.29± 3.69), (15.72 ± 0.79)kU/L] compared to the control[ (14.08 ± 1.99),(12.91 ± 3.97)kU/L, all P< 0.05] ; the level of MDA was obviously higher in rats exposed to fluoride for 1,4 week [ ( 13.37 ± 4.38 ), ( 11.82 ± 2.08) μmol/L ] compared to the respective control[ (8.75 ± 3.24), (7.42 ± 2.62)μmol/L, all P < 0.05]; difference of SOD and GPx between control and high-fluoride groups was not statistically significant(all P > 0.05); the level of uric acid in serum was significantly higher in high-fluoride group for 1,4 week[ (89.53 ± 13.21 ), (88.47 ± 19.78 )μmol/L] compared to the control [ (77.79 ± 11.43 ), (65.42 ± i 3.42) μ mol/L, all P < 0.05 ], but the level of uric acid showed lower in high-fluoride group for 8,12 week [(67.21 ± 9.44), (73.95 ± 9.52)μmol/L] compared to the control [(77.79 ± 11.43), (65.42 ± 13.42)μmol/L]. Conclusions Effect of overdose fluoride on ALP is time-dependant. On the other hand,overdose fluoride stimulates the status of oxidative stress in a way unrelated to the exposure period.

One new neolignan identified as 2, 3-( trans) -dihydro-2-(4-hydroxy-3-methoxyphenyl) -3-[(beta-D-glucopyranosyloxy) methyl]-7-methoxybenzofuran-5-propenoic acid (1) and five known steroidal glycosides namely torvoside A(2), torvoside C(3), torvoside H(4), solanolactoside A (5), (25S)-6alpha-hydroxy-5alpha-spirostan-3-one-6-0-[alpha-L-rhamnopyranosyl-(1-->3-beta3)-beta-D-D-quinovopyr-anoside] (6) were isolated from the fruits of Solanum torvum. Their structures were elucidated on the basis of 1D, 2D NMR and MS spectroscopic analysis.

According to research results of the lipid-lowering Chinese medicine at home and abroad in recent years, the paper will elaborate on the research status of the antihyperlipidemia effects of chinese medicine from the aspects of its vitro screening model, effective monomer, compounding, single medicine and antihyperlipidemia traditional Chinese medicine patent prescription. Put the ideas of development and use on the antihyperlipidemia effects of chinese medicine effective monomer and components medicine compatibility, emphasize on through new medicine screening cell model to find the antihyperlipidemia effects of chinese medicine monomer and antihyperlipidemia mechanism, breakthrough the single mode to use the accumulate of experience in clinical research as the development of new drugs. Study against the changes of the single-ingredient fixed component, the modify of the effective components combination of different drugs, the component compatibility of the different pathological link and the properties of the effective monomer, accelerate the theoretical innovation about the combination of effective medicine monomer, improve the research levels of the medicine combination from pieces to component, make the action target, link, and mechanism of herbal pharmacology more clear, promote the new Chinese herbal research, the improvement of the clinical efficient and the theory innovation of traditional chinese medicine.

OBJECTIVETo observe the effect of Astragalus injection (AI) on left ventricular remodeling and left ventricular function in patients with acute myocardial infarction (AMI).

METHODSAMI patients were randomly divided into the AI group (54 cases) treated with AI and the control group (54 cases) treated with conventional treatment. Left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI), anterior endocardial segmental length (ASL), posterior endocardial segmental length (PSL) were assessed by echocardiogram at the 1st and the 4th week of treatment; and the cardiac systolic and diastolic functions were detected by nuclide gating cardiac blood pool imaging on the 4th week. Besides, the plasmic levels of lipid peroxide (MDA), count of endothelial cell (CEC) and superoxide dismutase (SOD) were determined before and after treatment.

RESULTSAt the 4th week, changes of LVEDVI, LVESVI and ASL in the AI group were not obvious, but increased significantly in the control group, the significant difference in comparison between the two groups was shown (P < 0.05). As compared with the control group, in the AI group, the left ventricular ejection fraction, left ventricular peak ejecting rate and left ventricular peak filling rate were higher, and the left ventricular time for peak filling rate was shorter, moreover, MDA and CEC were lower and SOD was higher. The difference between groups and between before and after treatment were significant (P < 0.01 or P < 0.05).

CONCLUSIONAI is one of the effective drugs in reversal of left ventricular remodeling and improving left ventricular function in patients with AMI.

Primary pigmented nodular adrenal disease (PPNAD) is a kind of autosomal dominant inherited disease. Patient in the study presented with Cushing's syndrome, and clinical and pathological diagnosis of PPNAD was confirmed. It is now confirmed that there are two relevant genes and their mutations may lead to PPNAD. This study showed no mutations in the patient, surpecting if there would be an alternative mechanism or a new gene in playing the role.
