The manufacturing process of the drill is introduced, and drilling experiments are carried out by using of the drill developed. As a result, not only it can drill holes with a high efficiency, but also a good quality of hole inlet and outlet can be obtained for such materials as glasses, marble, granite, Al 2O 3, etc. The prospect in practical application of the technique developed is also discussed.展开更多

Unlike bobcat of cauliflower, BcpCAL did not hold the terminating mutation in the fifth e-con. After crosses of cauliflower with Chinese cabbage, the resultant hybrids failed to form curd, which implicates the genetic complement of BcpCAL to the mutated Bob- CAL in the function of curd formation. One of CAL gene isolated from the hybrid apparently comes from the female parent (Chinese cabbage) even though there are a few of the biases substituted and deleted. The result offers the molecular and genetic evidences for the Study of biological function of CAL in morphological genetics of curd.展开更多

Recently, we have described a new automated method for the determination of total antioxidant capacity (TAC) in human serum and plasma.METHODS: We measured TAC and corrected TAC (CTACabstraction of interactions due to endogenous uric acid,bilirubin and albumin) in 52 patients with chronic liver diseases (41 patients with primary biliary cirrhosis (PBC),10 patients with chronic hepatitis C and 13 patients with viral HCV cirrhosis) as well as in 10 healthy controls. In 23 PBC patients measurement were also done 6 mo after treatment with ursodeoxycholic acid (UDCA). The TAC assay was based on a modification of the crocin bleaching assay. The results were correlated with routine laboratory measurements and the histological stage of PBC.RESULTS: There were no significant differences in TAC between the various groups. However, CTAC was considerably increased in the PBC group compared to controls and cirrhotics. Analysis of these patients according to disease stages showed that this increase was an early phenomenon observed only in stages I and II compared to controls, cirrhotics and patients with chronic hepatitis C).After 6 mo of treatment with UDCA, levels of CTAC decreased to those similar to that of controls.CONCLUSION: Patients in the early stages of PBC present with high levels of corrected total antioxidant capacity and this maybe related to the pathophysiology of the disease. UDCA treatment restores the levels of CTAC to control levels.展开更多

Methods:TCMSP database and literature mining were used to analyze the main effective components in XTH, and the targets were predicted by Swiss Target Prediction server according to AS mechanism. The potential targets were introduced into the FunRich database for target annotation and analysis, the path analysis was finally performed based on the FunRich databases. To determine the mechanism of action of XTH. Results:A total of 316 compounds, 117 targets, and 290 signaling pathways were identified. And 16 effective compounds, 39 common targets, and 43 pathways were associated with AS. Conclusions:The results showed that the flavonoids, phenols, organic acids and terpenoids of XTH could participate in the process of lipid metabolism, angiogenesis, oxidation, inflammation, endocrine metabolism, cell proliferation and apoptosis, It was further found that they could play the role of anti-Atherosclerosis through multi-component, multi-target, and multi-channel synergistically.展开更多

Grape seed proanthocyanidin extract (GSPE) has been reported to exert an antiatherogenic effect by inducing regression of atherosclerotic plaques in animal experimental studies. In this study, the antiatherogenic effect of GSPE has been investigated in clinical use. Methods Consecu- tive 287 patients diagnosed with asymptomatic carotid plaques or abnormal plaque free carotid intima-media thickness (CIMT) were ran- domly assigned to the GSPE group (n = 146) or control group (n = 141). The patients in the GSPE group received GSPE 200 mg per day orally, while patients in the control group were only enrolled in a lifestyle intervention program. Carotid ultrasound examination was per- formed at baseline and 6, 12, 24 months during follow-up. Mean maximum CIMT (MMCIMT), plaque score, echogenicity of plaques and ischemic vascular events were recorded. Results As anticipated, after treatment, GSPE resulted in significant reduction in MMCIMT pro- gression (4.2% decrease after six months, 4.9% decrease after 12 months and 5.8% decrease after 24 months) and plaque score (10.9% de- crease after six months, 24.1% decrease after 12 months and 33.1% decrease after 24 months) for the primary outcome, while MMCIMT and plaque score were stable and even increased with the time going on in control group. The number of plaques and unstable plaques also de- creased after treatment of GSPE. Furthermore, the carotid plaque can disappear after treatment with GSPE. The incidence rate for transitory ischemic attack (TIA), arterial revascularization procedure, and hospital readmission for unstable angina in GSPE group were statistically significant lower (P = 0.02, 0.08, 0.002, respectively) compared with the control group. Conclusions GSPE inhibited the progression of MMCIMT and reduced carotid plaque size in GSPE treated patients, and with extended treatment, the superior efficacy on MMCIMT and carotid plaque occurred. Furthermore, the GSPE group showed lower rates of clinical vascular events.展开更多

It mainly affects the scalp, forehead, lumbar, abdomen and four limbs. The skin lesions are firstly present in single or multiple pink edematous patches in varying sizes, and then change into primrose yellow or beige hardening, being smooth and shiny resembling wax.展开更多
