Chinese Traditional and Herbal Drugs 1994;0(01):-
Triptophenolide (TN) is a colorless crystalline plate isolated from ethyl acetate extracts of Tripterygium wilfordii. It can obviously inhibit the edema caused by xylol and mixture croton oil; and decrease the concentration of Vitamin C in the adrenal gland of mice.TN can remarkably inhibit the delayed type hypersensitivity (DTH) reaction induced by DNCB and BSA; and diminished the peripheral blood ANAE+lymphocytes in rats and micc.Moreover, TN can dramatically increase the amount of total serum complement and significautly decrcase the serum antibody products (1gG ) of rats and mice. The phagocytosis of perioneal exudate macrophages in mice present double effects in vitro. TN can promote the phagocytosis of macrophages at the small dosage, but at larger dosage, it showed inhibition.The results mentioned above showed that triptophenolide may be one of the main effective component of T.wilfordii for treating auto-immune diseases.

AIM: To investigate the influences of native and oxidized lipoprotein(a) on human arterial smooth muscle cell (SMC) proliferation, change of intracellular free calcium concentration ([Ca 2+ ] i) and the protective effect of sodium ferulate(SF). METHODS: Lp(a) was oxidized by Cu 2+ and the extent of oxidation was assessed by the MDA content.Human SMC were incubated in culture media with SF for 12 h, then exposed to Lp(a) and oxidized-Lp(a), respectively. MTT colorimetry and flow cytometry were used to evaluated the proliferation of SMC and flurorescent indicator Fura-2/AM was used to determined [Ca 2+ ] i. RESULTS: ox-Lp(a) significantly promoted proliferation of SMC and increased[Ca 2+ ] i compared with Lp(a). SF(40,80 mg/L) remarkedly inhibited SMC proliferation and decreased the rising of [Ca 2+ ] i induced by ox-Lp(a) in a dose-dependent manner, but no effect on SMC proliferation and the increase in [Ca 2+ ] i induced by Lp(a).CONCLUSION: ox-Lp(a) induces the strong growth-promoting effect in SMC through increasing in [Ca 2+ ] i, which might be one of the cellular mechanisms responsible for the higher atherogenic potential of ox-Lp(a) compared with Lp(a), and this process can be prevented by inhibiting of oxidation by SF.

Objective:To explore the correlation between the characteristics of contrast-enhanced sonography of intraoperative glioblastoma multiform (GBM) and molecular markers of isocitrate dehydrogenase-1(IDH1).Methods:A retrospective analysis were performed in 30 patients who underwent neurosurgery and pathologically confirmed to be GBM at Beijing Tiantan Hospital from May 2018 to April 2019. All neurosurgical glioblastoma patients after craniotomy underwent conventional ultrasound and contrast-enhanced ultrasound(CEUS) guided navigation. The characteristics of the ultrasound imaging (whether the tumor involves the structure of the corpus callosum, the clarity of the tumor boundary after enhanced ultrasound and whether the tumor has necrotic areas with enhanced ultrasound images) were analyzed. The ratio between tumor necrosis area and whole tumor area (N/W) was measured, and the correlation with IDH1 gene expression was analyzed.Results:There were statistical differences in clarity of tumor boundary after CEUS and tumor necrosis after CEUS between positive IDH1 and negative IDH1 groups(all P<0.05). The positive expression of IDH1 was negatively correlated with the N/W area of the contrast-enhanced ultrasound mode( r=-0.756, P<0.05), suggesting that the expression level of IDH1 gene was negatively correlated with the area of tumor necrosis. Conclusions:Ultrasound contrast agent examination can more accurately distinguish the active proliferation area, hemorrhagic necrosis area and peripheral edema area of glioblastoma. Accurately identifying the extent of tumor necrosis area through ultrasound contrast agent examination can predict expression of IDH1.

OBJECTIVETo analyze the distribution characteristics of hirsutism and the law of meridian differentiation in polycystic ovarian syndrome (PCOS).
METHODSFor the patients of PCOS, the modified Ferriman-Gallwey score (mF-G score) was adopted to evaluate the hirsutism distribution. The clementine data mining software was used to analyze the distribution region of hirsutism and the correlation with meridian.
RESULTSA total of 141 patients of PCOS participated in the study. The most common regions of hirsutism were in the upper lip (50.35%) and the lower abdomen (34.04%). The higher frequencies of hirsutism at two regions were at the upper lip and lower abdomen (24.82%), the upper lip and chest (12.06%) and the upper lip and thigh (11.35%). In the analysis on the correlation of the upper lip, lower abdomen and chest with other regions, hirsutism was more common in the nearby regions. In reference to the running course of meridian, the frequencies of hirsutism from high to low were the conception vessel (63.12%), the thoroughfare vessel (61.70%), the liver meridian of foot-(58.16%) and the stomach meridian of foot-(57.45%). According to:-, the high incidence of hirsutism (59.57%) resulted from the change ofand blood inmeridian. .
CONCLUSIONBlood plays the important role in the growth of body hair. Regarding theattribution, the incidence of hirsutism at theregions is higher than theregions. The occurrence of hirsutism is closely related toand blood changes in meridians. The conception vessel, the thoroughfare vessel, the liver meridian of foot-andmeridian act highly on the disease.
