Objective To correlate dynamic parameters at contrast enhanced CT and interstitial fibrosis grade of non-small cell lung cancer (NSCLC). Methods Twenty-nine patients with NSCLC were evaluated by multi-slice CT. Images were obtained before and at 20,30,45,60,75,90,120,180,300,540,720,900 and 1200 s after the injection of contrast media, which was administered at a rate of 4 ml/s for a total of 420 mg I/kg body weight. Washout parameters were calculated. Lung cancer specimens were stained with hematoxylin-eosin stain and collagen and elastica double stain. Spearman test was made to analyze correlation between dynamic parameters and interstitial fibrosis grade of tumor. Results Twentynine NSCLC demonstrated washout at 20 min 12. 1 (0. 32-58.0 ) HU, washout ratio at 20 minutes 15.3% (0. 3%-39.2% ), slope of washout at 20 minutes 0. 0152 %/s ( 0. 0007%/s-0. 0561%/s ).Interstitial fibrosis of 29 lesions was graded as grade Ⅰ (10), grade Ⅱ (14) and grade Ⅲ (5). There were significant correlation between washout at 20 min ( r = - 0. 402, P ＜ 0. 05 ), washout ratio at 20 min ( r =-0.372,P＜0.05), slope of washout ratio (r = -0.459,P ＜0.05) and interstitial fibrosis grade in tumors. Conclusion NSCLC washout features at dynamic multi-detector CT correlates with interstitial fibrosis in the tumor.

Objective To evaluate the efficacy and safety of sunitinib as post-operative adjuvant therapy in patients with high-risk renal cell carcinoma (RCC).Methods A total of 60 patients with resected,histologically confirmed clear cell RCC were enrolled in this study.Patients received orally sunitinib either at a dose of 50 mg on treatment schedule (once daily for 4 weeks followed by 2 weeks off) or at a dose of 37.5 mg once daily for three 6-week cycles from 1 month after surgery.Results All the 60 patients tolerated Sunitinib treatment well and no patient discontinued treatment due to adverse events.Most adverse events were grade Ⅰ to Ⅱ.The most frequently reported adverse events were neutropenia (56.7％),thrombocytopenia (53.3％),leucopenia (48.3％),hand-foot syndrome (46.7％) and hypertension (36.7％).The most frequently reported grade 3 or 4 toxicities were thrombocytopenia (25.0％),neutropenia (15.0％),hand-foot syndrome (11.7％) and leucopenia (8.3％).The majority of adverse events occurred within the first 1-2 cycles of sunitinib treatment,and was ameliorated 1 month after 3 cycles finished.No irreversible adverse event was observed.As of April 5,2012,no recurrence occurred in patients except one death due to cerebrovascular accident unrelated to treatment,with both 6-month and 9-month disease-free survival rate of 100％.Conclusions Myelosuppression occurred less frequently in high-risk RCC patients treated with sunitinib as operative adjuvant therapy than in advanced RCC patients,with a better benefit trend.However,long-term follow-up data are needed to further confirm the efficacy of sunitinib in the adjuvant setting.

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

OJECTIVETo observe the effect of tianma gouteng decoction (TGD) on the endothelial function and the renal protein expression of spontaneously hypertensive rats, and to analyze its possible mechanism.

METHODSTotally 18 6-week-old SHR were randomly divided into 3 groups according to randomized block design, the SHR control group, the TGD group, and the captopril group, 6 in each group. Meanwhile, Wistar Kyoto (WKY) rats of the same age were recruited as a WKY control group. Rats in the TGD group were administered with TGD at the daily dose of 10. 260 g/kg. Rats in the captopril group were administered with captopril at the daily dose of 3. 375 g/kg. 2 mL/100 g distilled water was administered to rats in the SHR control group and the WKY control group. All medication was performed by gastrogavage once per day till rats were 24 weeks old. Changes of blood pressure were measured once per two weeks. The relaxation of the thoracic aorta and the superior mesenteric artery was determined by vascular ring in vitro to reflect the endothelial function. The total renal protein was separated by two-dimensional electrophoresis (2-DE). The significantly deviated protein was verified by Western blot.

RESULTS(1) Compared with the SHR control group, blood pressure was significantly lowered in rats (10 - 24 weeks old) of the captopril group (P <0.01, P <0.05). The hypotensive effect of TGD was obvious at the beginning of hypertension (10 -12 weeks) (P <0. 01). But along with the progression of hypertension, its hypotensive effect was not obvious (P>0. 05). (2) Compared with the SHR control group, the relaxation of the superior mesenteric artery was obviously improved in the TGD group (P <0. 05); the relaxation of the thoracic aorta and the superior mesenteric artery was obviously superior in the WKY control group (P <0. 01, P <0. 05). But there was no statistical difference in each relaxation index between the captopril group and the SHR control group (P >0. 05).(3) RESULTS: of 2-DE found 16 significantly differential renal protein, mainly involved nitric oxide (NO) system, oxidative stress, and cytoskeleton-related proteins. Results of Western blot showed that TGD could significantly improve expressions of Cu-Zn superoxide dismutase (SOD), N(G, N(G)-dimethylarginine dimethylaminohydrolase 2 (DDAH2), and pterin-4-alpha-carbinolamine dehydratase 1 (PCBD1) (P <0. 05).

CONCLUSIONGTD could protect the endothelial function of the superior mesenteric artery in SHR, and its intervention mechanism of hypertension induced early renal injury might be relevant to regulating the NO system and antioxidative stress.

Objective To investigate the roles of five scoring systems including model for endstage liver disease (MELD), Child-Turcotte-Pugh (CTP), Mayo, MESO and MELD-Na scoring systems, in predicting the prognosis of patients with chronic severe hepatitis. Methods The clinical data of 213 patients with chronic severe hepatitis were retrospectively studied. The five scoring systems were applied respectively to evaluate the scores in survival group and death group. The capability of these five scoring systems to predict the prognosis of severe hepatitis were compared by the receiver operating characteristic (ROC) curve, area under curve (AUC) and cut-off value.Measurement data were compared by group t test. The comparisons of AUC among scoring systems were done using MEDCLAC software. Results The scores of death group evaluated by MELD, CTP,Mayo, MESO or MELD-Na scoring systems (30.6 ± 9.5, 11.3 ± 1.5, 10.4 ± 1.3, 2.3 ± 0.8 and 39.0 ± 11.8, respectively) were consistently higher than those of survival group (21.1± 6.8, 10.6 ±1.6, 9.0±1.5, 1.6±0.5 and 22.6±8.2, respectively) (P＜0.01). The values of AUC of these five systems were 0.810, 0.623, 0.749, 0.829 and 0.885, respectively. The Youden's indexes of these five systems were 0.507, 0.175, 0.389, 0.528 and 0.650, respectively. Conclusions The CTP scoring systems can not predict the prognosis of chronic severe hepatitis very well. The Mayo scoring systems can partially predict the prognosis. On the contrary, MELD, MESO and MELD-Na systems can successfully predict the disease prognosis, and the score of MELD-Na system shows the best correlation with the prognosis.

Expressions of interleukin-6 (IL-6) and its receptor (gp80、gp130) in 8 patients with Graves' disease (GD) were compared with those in 8 euthyroid patients with nodular goiter or benign thyroid adenoma. The thyroid tissues of GD expressed significantly higher IL-6 mRNA, gp130 mRNA and IL-6 protein than those of the control group, suggesting that activated IL-6/gp130 signal pathway in the thyroid tissue may contribute to the pathogenesis of GD.
