Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

Growth year is one of the important factors for the quality of Polygala tenufolia. In this study, primary metabolites and secondary metabolites were compared in 1, 2 and 3 years old P. tenufolia cultivated in Shaanxi Heyang. The samples were subjected to ultra-high performance liquid chromatography (UPLC)-quadrupole time-of-flight mass spectrometry (Q-TOF MS) and nuclear magnetic resonance (NMR) analysis, and the obtained data were analyzed using principal component analysis (PCA) and other statistical analysis methods. In addition, content and correlation of different metabolites were also calculated. The results showed no significance between main component contents in 2 year-old and 3 year-old P. Tenufolia, but 1 year-old was statistically different. The contents of primary metabolites, such as fructose, sucrose, and choline increased as time goes on, while glycine and raffinose decreased. The contents of secondary metabolites, such as onjisaponin Fg, polygalasaponin XXVIII, polygalasaponin XXXII increased, while polygalaxanthone III and parts of oligosaccharide multi-ester including tenuifoliose A, tenuifoliose C, tenuifoliose C2 and tenuifoliose H decreased with the extension of the growth years. Growth years has important impact on the quality of P. tenuifolia and the existing growing years of commodity P. tenuifolia have its scientific evidence. This study supplied a new method for the quality evaluation of Chinese medicinal materials.

This report documents the treatment of a giant aneurysm of the internal carotid artery bifurcation with a fistula to the cavernous sinus, which appeared following closed head trauma. A 39-year-old man suffered from a blunt head trauma in an automobile accident. Two weeks after the trauma, progressive chemosis of left eye was presented. Four months after the trauma, digital subtraction angiography showed an internal carotid artery bifurcation aneurysm, with drainage into the cavernous sinus. The lesion was successfully obliterated with preservation of the parent artery by using coils in conjunction with Onyx. Follow-up angiography obtained 3 months postoperatively revealed persistent obliteration of the aneurysm and fistula as well as patency of the parent artery. Endovascular treatment involving the use of coils combined with Onyx appears to be a feasible and effective option for treatment of this hard-to-treat lesion.

OBJECTIVETo assess the effect of Qingfei Quyu Decoction (QQD) in preventing radiation pneumonitis in esophageal carcinoma patients by concurrent using it with chemoradiotherapy.

METHODSA total of 120 patients with mid-late stage esophageal carcinoma were randomly assigned to the treatment group (60 cases) and the control group (60 cases). All patients received concurrent radiochemotherapy. Patients in the treatment group additionally took QQD, one dose per day for 8 successive weeks. The incidence of radiation pneunonitis was compared between the two groups. The improvement rates of short-term benefit rate, Karnofsky performance scale (KPS), and body weight (BW) improvement rate were calculated between the two groups. The 1-and 2-year overall survival rates were compared between the two groups.

RESULTSThe incidence of radiation pneunonitis was 8.93% (15/56) in the treatment group and 18.64% (11/59) in the control group (P < 0.05). The short-term benefit rate was 92.86% (52/56) in the treatment group and 69.49% (41/59) in the control group (P < 0.05). Besides, the KPS and BW improvement rate were higher in the treatment group [89.29% (50/56) and 83.05% (49/59) ] than in the control group [80.36% (45/56) and 66.10% (39/59)] (P < 0.05). The 1-and 2-year overall survival rate were 66.07% and 35.71% in the treatment group, higher than those of the control group (61.02% and 30.51%; P > 0.05).

CONCLUSIONConcurrent using QQD with chemoradiotherapy for treating esophageal carcinoma patients could lower the incidence of radiation pneumonitis, attenuate the degree of radiation induced lung injury, improve clinical benefit rate, and elevate their QOL.

OBJECTIVETo explore the expression of gut-enriched Kruppel-like factor 4(KLF4) in gastric cancer, and its association with prognosis.

METHODSSurgical specimens were collected from 264 patients undergoing radical surgery between 2004 and 2009 in the Affiliated Qianfoshan Hospital, Shandong University. KLF4 mRNA level of specimens was detected by real-time PCR. KLF4 protein expression was measured by immunohistochemistry on tissue microarray, which contained primary gastric cancer, corresponding para-cancerous tissue, and paired lymph node metastases.

RESULTSReal-time PCR revealed that mRNA level of KLF4 was down-regulated in gastric cancer compared with paired normal gastric mucosa. Immunohistochemistry on tissue microarray showed gastric cancer tissues had significantly lower KLF4 levels compared with paired normal gastric tissues. By univariate and multivariate analysis, KLF4 was a significant predictor of survival and recurrence.

CONCLUSIONKLF4 expression is significantly down-regulated in gastric cancer, and is an independent predictor of survival and recurrence.

OBJECTIVETo observe the dynamic expression of calcium-sensing receptor(CaSR) in myocardium of diabetic rats.

METHODSThirty male Wistar rats were randomly divided into 3 groups including control, diabetic-4 week and diabetic-8 week groups(n = 10). The type 2 diabetes mellitus models were established by intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) after high-fat and high-sugar diet for one month. The cardiac morphology was observed by electron microscope. Western blot analyzed the expression of CaSR, phospholamban (PLN), a calcium handling regulator, and Ca+-ATPase(SERCA) in cardiac tissues.

RESULTSCompared with control group, the expressions of CaSR and SERCA were decreased, while the expression of PLN was significantly increased in a time-dependent manner in diabetic groups. Meanwhile diabetic rats displayed abnormal cardiac structure.

CONCLUSIONThese results indicate that the CaSR expression of myocardium is reduced in the progression of DCM, and its potential mechanism may be related to the imnaired intracellular calcium homeostasis.
