AIM:To verify whether arterial-phase contrast-enhanced ultrasonography(CEUS) of tumor parenchymal tissue is useful for evaluation of anti-angiogenesis ***:Rabbits with liver tumor were subjected to CEUS,and images of the nodular maximal diameter in vascular phase were *** analysis was performed to plot the time intensity curve(TIC) at the tumor parenchyma,which set the diameter of the region of interest of intensity *** TIC was calculated to obtain the time to peak intensity(TPI) and the magnitude of *** were randomly assigned to a treatment group with sorafenib and a control *** weeks later,the same ultrasound examination was repeated followed by pathological testing to assess the effect of sorafenib on the liver ***:In four rabbits in the treatment group,the rate of change of tumor size was decreased comparedwith that of the control(the rate 2.3 vs 7.9,P = 0.02).The TPI of the treatment group elongated significantly(the rate 3.1 vs 1.1,P = 0.07 for SonoVue,2.0 vs 0.88,P = 0.09 for Sonazoid).The magnitude of PI showed no significant *** pathological examination,capillary diameters in the treatment group were significantly smaller than those in the control group(26.4 vs 42.8 μm,P = 0.013).CONCLUSION:Analysis of the TIC in the arterial phase of tumor tissue could evaluate the efficacy of antiangiogenesis drug treatment in liver tumor.

The apparent degradation rate constant of fluticasone propionate(FLT) in 0.1 M NaOH:methanol=1:1 at 37 °C was previously reported to be 0.169 ± 0.003 h^(-1), and four degradation products(products 1–4) were observed in the solution. The aims of the present study were to assess the degradation rates of FLT in other alkaline solutions and clarify the chemical structures of the four degradation products in order to obtain basic data for designing an enema for inflammatory bowel disease. The apparent degradation rate constants in 0.05 M NaOH and 0.1 M NaOH:CH_3CN=1:1 were 0.472 ± 0.013 h^(-1) and 0.154 ± 0.000 h^(-1)(n=3), respectively. The chemical structures of products 1–4 in 0.1 M NaOH:methanol=1:1 were revealed by nuclear magnetic resonance(NMR)and mass spectrometry data. The chemical structure of products 2 was that the 17-position of the thioester moiety of FLT was substituted by a carboxylic acid. The degradation product in 0.1 M NaOH:CH_3CN=1:1 was found to be product 2 based on ~1H NMR data. The degradation product in 0.05 M NaOH was considered to be product 2 based on the retention time of HPLC. These results are useful for detecting the degradation products of FLT by enzymes of the intestinal bacterial flora in the large intestine after dosing FLT as an enema.

Background: Xanthogranulomatous inflammation of the female reproductive organs is a rare chronic inflammation. In most reported cases, the lesion was limited to the endometrium and fallopian tubes. Here, we report two cases of xanthogranulomatous inflammation of the myometrium with a history of endometrial biopsy. Case Reports: In two cases, myometrial xanthogranulomatous inflammation destroyed the myometrium. This inflammation developed into surrounding pelvic organs, resulting in uterine perforation. Conclusion: When inflammatory lesions are found after intrauterine manipulation, the possibility of developing xanthogranulomatous inflammation should be considered. If antibiotics are ineffective, prompt surgical treatment is necessary.

Complex hydride materials have been widely investigated as potential solid electrolytes because they have good compatibility with the lithium metal anodes used in all-solid-state batteries. However, the development of all-solid-state batteries utilizing complex hydrides has been difficult as these cells tend to have short cycle lives. This study investigated the capacity fading mechanism of all-solid-state lithium–sulfur(Li–S) batteries using Li4(BH4)3I solid electrolytes by analyzing the cathode microstructure. Crosssectional scanning electron microscopy observations after 100 discharge–charge cycles revealed crack formation in the Li4(BH4)3I electrolyte and an increased cathode thickness. Raman spectroscopy indicated that decomposition of the Li4(BH4)3I solid electrolyte occurred at a constant rate during the cycling *** combat these effects, the cycle life of Li–S batteries was improved by increasing the amount of solid electrolyte in the cathode.
