Objective To compare the clinical efficacy of Rivaroxaban and Warfarin in the treatment of lower extremity deep vein thrombosis.Methods From January to December 2015,51 patients of deep vein thrombosis of the lower limb divided into.Warfarin group (21 cases) and Rivaroxaban group (30 cases).The time of each therapy lasted for 3 months or longer.The characteristics and the change of lower limb venous patency rate in two groups of patients were analyzed to evaluate the curative effect.Results Rivaroxaban group had shorter therapy time than Warfarin group.The lower limb venous patency rate in Rivaroxaban group were higher than that in Warfarin group (85.7％ vs.60％,P ＜0.05).Ultrasonography showed partial patency in 5 mixed thrombus patients of Warfarin group,while complete patency in 2 and partial patency in 3 of Rivaroxaban group.Normalized rate in peripheral venous thrombosis patients of Rivaroxaban group were higher than Warfarin group (84％ vs.25 ％ P ＜ 0.001).Conclusions Rivaraxaban is superior to Warfarin in the complete recanalization of DVT,while safe and reliable.

The correct rates of the four knowledge points were different among different gender and the degree of education,which was higher in female than in male,and higher in high education degree than in the other(P

?-arbutin is biosynthesized by whole cell method with Xanthomona maltophilia BT-112.The conditions for cell biosynthesized ?-arbutin are investigated as follows:temperature,25℃;concentration of hydroquinone,30mmol/L;mol ratio of sucrose and hydroquinone,20∶1;time course of ?-arbutin biosynthesis,45 hours;rotational speed,160r/min;concentration of Xanthomona maltophilia BT-112,85g/L;concentration of K-2HPO-4-KH-2PO-4 buffer solution,25mmol/L;pH of K-2HPO-4-KH-2PO-4 buffer solution,8.0.Under the above optimal conditions,the maximum of molar conversion yield based on the amount of hydroquinone supplied reaches 86.7%.

The polymorphism and thermostability of nirmatrelvir, the main antiviral component of the oral COVID-19 treatment drug, were studied. Four polymorphs of nirmatrelvir were prepared by recrystallization methods. Among them, Form 1 and nirmatrelvir methyl tert-butyl ether solvate (Form 2) had been reported in the literature, while nirmatrelvir isobutyl acetate solvate (NMTW-IBAC) and nirmatrelvir ethyl acetate solvate (NMTW-EA) are two new solvates. The crystal structures were characterized by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis and differential scanning calorimetry. The thermostability of polymorphism and crystalline transformation were also investigated by combining Hirshfeld surface analysis and interaction energy analysis. The results showed that nirmatrelvir Form 1 belongs orthorhombic crystal system with the space group P2₁2₁2₁ and one nirmatrelvir molecule included in the asymmetric unit, which has the same crystal structure as nirmatrelvir Form 4 reported in the literature. Owing to its larger thermal expansion, the differences in crystallographic parameters obtained at different temperatures were found between Form 1 and Form 4. Three solvates of nirmatrelvir belonged to the iso-structural with monoclinic crystal system and the space group P2₁, in which the asymmetric unit contains one nirmatrelvir molecule and one solvent molecule. The thermal analysis results showed that nirmatrelvir Form 1 was a solvent-free crystal form with the best thermal stability and the strongest intermolecular hydrogen bonding. Among the three solvates, NMTW-EA has the worst thermal stability and the weakest hydrogen bonding interaction between the nirmatrelvir molecule and the solvent molecule. The energy framework of nirmatrelvir solvates showed that the closer the arrangement between solvent and nirmatrelvir molecules, the greater the total interaction energy between solvent and nirmatrelvir molecules. The phase transition studies of the three solvates showed that NMTW-IBAC and NMTW-EA were transformed into amorphous after desolvation, respectively, while Form 2 undergoes oiling during desolvation. The research provides theoretical guidance for the analysis, identification and quality control of nirmatrelvir polymorphs.

As a novel transdermal drug delivery technology of minimally invasive, safe and efficient, microneedles have received increasing attention. The microchannels formation by microneedles onto the skin is a prerequisite and key for microneedles to deliver drugs. However, there is still a lack of systematic evaluation in skin microchannels. This review summarized influencing factors and evaluation methods in microchannels formation and healing by microneedles, including geometric parameters, materials for preparation, drugs, penetration parameters, differences among the skin of subjects, and presence or absence of occlusion. This review provides reference for other scholars to further study the effectiveness and security of microneedle applications.

Objective To study the changes of soluble intercelluar adhesion molecule-1 (sICAM-1) in serum of neonates with hy-poxic-ischemic encephalopathy (HIE),and significance of changes of serum sICAM-1 in HIE pathogenesis. Methods There were 17 controls of neonates and their sICAM-1 concentrations in serum were detected with enzyme-linked immunosorbent assay (ELISA) at the critical stage and at the beginning of convalescent stage in 36 cases of HIE neonates and 17 normal neonates. The data were analyzed with analysis of variance, Newman-Keuls q test. Results The concentrations of sICAM-l[(216.64?85.32)?g/L] at the critical stage of 36 cases HIE neonates were significantly higher than those [(6. 16?4.05) ?g/L ] of control group (q = 17. 42 P
