Qinghuachang Decoction Inhibited NF-kappaB Activation in LPS-induced Human Enterocytes / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore anti-inflammation and mechanism of Qinghuachang Decoction (QD) by using LPS stimulated differentiated colon cancer Caco-2 cells (as an inflammation model of human enterocytes).</p><p><b>METHODS</b>QD was prepared. Human colonic epithelial Caco-2 cells were cultured. Expressions of TNF-alpha and IL-8 were determined using ELISA. Expressions of inhibitory Kaba protein (IkappaB-alpha), phosphorylated inhibitory Kaba protein (p-lkappaB-alpha), nuclear transcription factor p50 (p50), and nuclear transcription factor ReIA (ReIA) protein were determined by Western blot.</p><p><b>RESULTS</b>Compared with the negative control group (without LPS stimulation), LPS stimulated the release of IL-8 and TNF-alpha in Caco-2 cells (P < 0.05). QD treatment could reduce the secretion of TNF-alpha and IL-8 induced by LPS in a dose dependent manner (P < 0.05). QD at 0, 5, 10, and 50 microg/mL had no significant effect on Caco-2 cell survival rates (P > 0.05), with no statistical difference among various concentrations (P > 0.05). QD could significantly suppress nuclear factor-kappa B (NF-kappaB) phosphorylation stimulated by LPS. The expression of p-IKappaB-alpha was decreased with increasing concentrations of QD (P < 0.05). There was no obvious change in IKB-alphaB expressions (P > 0.05). Expressions of p50 and ReIA decreased with increasing concentrations of QD (P < 0.05). Both of them were in a dose dependent manner.</p><p><b>CONCLUSION</b>QD inhibited LPS mediated NF-kappaB activation, which might be one of its mechanisms for treating inflammatory bowel disease (IBD).</p>

Forensic identification by coding of frontal sinus characteristics of CT / 法医学杂志

OBJECTIVE@#To explore observing parameters of frontal sinus using reconstructive coronal nose bone sections of the head CT images and to establish the special identification codes.@*METHODS@#CT images of the frontal sinus were analyzed by using distance measurement and morphological description. The discrimination codes of frontal sinus identification were: the number of right partial septa, shape-the location of the central septa, shape-the number of left partial septa, shape; the number of arches of right upper scalloping (the location of the right highest scalloping, the location of the right lowest scalloping)-the number of arches of left upper scalloping (the location of the left highest scalloping, the location of the left lowest scalloping); the width, height of the right sinus-the total width of sinus-the width, height of the left sinus.@*RESULTS@#The identification codes of the frontal sinus were highly variable individually, but the codes were not statistically differences between males and females (P > 0.05).@*CONCLUSION@#The identification codes of frontal sinus could be used for forensic individual identification, but not for sex determination.

Influence of Xianglingwan on dysmenorrhea and serum CA125 in treating patients with endometriosis / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the influence of Xianglingwan on dysmenorrhea and serum CA125 in treating patients with endometriosis.</p><p><b>METHOD</b>A total of 54 patients with endometriosis and without medical complications were random selected. Xianglingwan was administered from the fifth day of the menstrual cycle for 3 weeks every month as a therapeutic course, and three months for a therapeutic period. Pelvic type B ultrasonograph and blood CA125 were detected before and after treatment. Visual analogue scale was admitted to evaluate the dysmenorrhea.</p><p><b>RESULT</b>The serum CA125 reduced obviously after therapy. There was a significant difference between them (P < 0.01). The symptom of dysmenorrhea also reduced obviously after treatment. There was a significant difference between them (P < 0.05).</p><p><b>CONCLUSION</b>Xianglingwan can treat edometriosis effectively, and has less adverse reactions, it can also reduce the symptom of dysmenorrheal and the serum CA125.</p>
