Objective To study the proportion of cyclic vomiting syndrome(CVS) developing to migraine by the medium term prognosis,and explore the relationship between CVS and migraine.Methods Twenty-eight of 38 cases who had identified in our clinical records were traced ,each child was matched to a control,and they all conducted a telephone interview by a standardized question.Results Ninteen(46%) of the subject had continued CVS and(or) migraine,the prevalence of past or present migraine in subjects(46%)was significantly higher than that in control group(10.7%)(P=0.003).Conclusion The progonosis of CVS is closely related to migraine,many of the suffers of CVS tend to develop migraine.

ObjectiveTo evaluate the effects on serum homocysteine(Hcy) level,vascular function and carotid intima-media thickness(IMT) in metformin-treated diabetic patients with or without supplementation with folate and Vitamin B12.MethodsA total of 100 newly diagnosed diabetic type 2patients were divided into two groups by random digits table with 50 cases each,90 patients completed study.Forty-seven participants (control group) received a 6-month course of metformin treatment,43 patients (treatment group) received mefformin,folate and Vitamin B12 treatment.The levels of serum Hcy,endothelin-1 (ET-1),carotid IMT,large or small arterial elasticity index (C1,C2),flow-mediated dilatation (FMD) of the brachial artery were evaluated before and after treatment.ResultsThe level of serum Hcy in control group significantly increased compared with before treatment[ (13.4 ± 2.7)μ mol/L vs.(11.1 ± 1.9)μ mol/L],hut the level of serum Hcy in treatment group significantly decreased compared with before treatment [ (9.2 ± 1.8 ) μ mol/L vs. ( 11.3 ± 2.0) μ mol/L ],there was significant difference(P ＜ 0.05 ).A beneficial effect was observed in the serum ET-1,FMD,carotid IMT and C2 in treatment group[ (20.0 ± 6.2)ng/L,( 15.8 ± 7.6)％,(0.8 ± 0.2) mm,(4.1 ± 2.1 ) ml/mm Hg ( 1 mm Hg =0.133 kPa) × 100 vs. (31.3 ±10.1 ) ng/L,(9.7 ± 4.5)％,( 1.1 ± 0.4) mm,(2.3 ± 1.0) ml/mm Hg × 100 ] (P ＜ 0.05).The levels of ET-1,FMD,carotid IMT and C2 after treatment in control group [ (24.8 ± 6.8) ng/L,( 12.9 ± 6.3 )％,(0.9 ± 0.3)mm,(3.0 ± 1.4) ml/mm Hg × 100] had significant difference compared with before treatment [ (30.6 ± 8.7)ng/L,(9.8 ± 4.6)％,( 1.0 ± 0.3) mm,(2.2 ± 0.9) ml/mm Hg × 100](P＜ 0.05).However,the results were improved significantly in treatment group than those in control group (P ＜0.05).In treatment group,significant correlation were detected between changes of Hcy and ET- 1 (r =0.43,P ＜ 0.05 ),carotid IMT(r =0.56,P ＜ 0.05),FMD (r =-0.54,P ＜ 0.05 ),C2 (r =-0.37,P ＜ 0.05 ).ConclusionsAdministration of folate and Vitamin B12 can reduce the levels of serum Hcy and ET-1 in metformin-treated type 2 diabetic patients,which exert beneficial effect on carotid IMT,FMD and C2.

Protein kinase Cε (PKCε) is a transforming oncogene and plays an important role in many cellular processing. In the present paper, we review the development of experimental researches on the acute-chronic pain transformation. Results indicated that prostaglandin E2 (PGE2) / EP1 receptor-Gq-PKCε is an important signaling pathway to modulate chronic pain in peripheral dorsal root ganglion (DRG) neurons, and also plays a role in the later stage of hyperalgesia during transformation from acute to chronic pain. PKCε in DRG neurons induces mechanical and thermal hypersensitivity respectively by over expression of transient receptor potential vanilloid 1 (TRPV1) and TRP ankyrin-1 (TRPA1), further mediating the transformation from acute to chronic pain. Whereas, PGE2-evoked activation of EP1-Gq-PKCε signaling may be the key link in initiating the pain translation process through regulating downstream TRPA1 and TRPV1. Electroacupuncture (EA) has been used to effectively relieving various types of acute and chronic pain for decades, and can significantly inhibit the expression of PKCε and its upstream and downstream molecules. Therefore, it can be inferred that there exists a possibility of EA interventions in interfering the transformation from acute to chronic pain by regulating peripheral PKCε signaling pathway.

Objective To explore acute toxicity of succimer on mice.Methods Twenty Kunming mice(10 males and 10 females) weighting approximately (21.2?2.3)g were acclimatized for 3 days prior to dosing,then were divided into control group and experiment group with 10 mice in each group according to body weight.Fasted for 12 hours,the mice in experiment group received intragastric administration of 160mg DMSA in deionized water in 24 hours,and the control group received the same volume of deionized water,and then they were observed for 7 days.Blood was collected into heparinized-tubes by removal of eyeball.All mice were sacrificed and brain,heart,liver and kidney were removed and washed with normal saline.The activity or amount of BUN,Scr,AST,ALT,SOD, GSH-PX and MDA were analyzed.Results (1)Given 160rag DMSA in 24 hours,gastrointestinal symptoms were main side effects.During the observation,experiment group lost weight due to the decrease of food-intake ,and some mice had slight hydroabdomen.(2)High dose of DMSA caused a significant inhibition of GSH-PX(P0.05).The hepatic cell was damaged accord- ing to the significant raise of MDA in liver(P0.05),which was related to acute toxicity on liver.Conclusion Succimer could inhibit the antioxidarrt systems and could do damage to liver and kidney.

BACKGROUND: Despite modem diagnostic, staging, and therapeutic advances, esp. with molecular biologic techniques, the 5-year survival rate of all cases of lung cancer does not exceed 15%. Also, the incidence of lung cancer of both sex in Korea is increasing year by year and the lung cancer is one of the leading causes of cancer death. Therefore, it is strongly needed to develop the new combination of treatment modalities including neoadjuvant chemotherapy and to identify tumor specific characteristics with staging or prognostic markers. Here we present the clinical significance of several biologic tumor markers to use as a prognostic markers in patients with non-small cell lung cancers. METHOD: The survival has correlated with the expressibility of proliferative cell nuclear antigen (PCNA), epidermal growth factor receptor(EGFR), p53 and/or blood group antigen A(BGAA) using immunohistochemistry in 46 patients with non-small cell lung cancers. RESULTS: 1) The expression rates of PCNA, EGFR, p53 and BGAA were 80.6%, 61.3%, 45.9% and 64.3%, respectively and those were not correlated to cell types or clinical stges. 2) The expression of BGAA was correlated with better survival in median survival and in 2-year survival rate and that of PCNA was correlated with worse survival in median survival and 2-year survival rate. 3) The expression of EGFR or p53 was not valuable to predict prognosis in non-small cell lung cancers. 4) With simultaneous applications of PCNA, EGFR and p53 immunostain, the patients with 2 or more negative expressions showed better prognosis than the patients with 2 or more positive expressions. CONCLUSION: It is suggested that the expression of blood group antigen may be a positive prognostic factor and that of PCNA may be a negative prognostic factor. Also, the combination of expressions of PCNA, EGFR and p53 may be used as a negative prognostic factor.

To observe the serum samples and the anti-inflammatory effect of Tripterygium wilfordii in treating RA by using the pharmacokinetic-pharmacodynamic model, make a correlation analysis on concentration-time and effect-time curves, and explore RORγt, IL-17, STAT3, IL-6 mRNA transcriptional levels in rats by PCR. Methotrexate, tripterine and high-dose T. wilfordii could down-regulate RORγt, IL-17, STAT3, IL-6 mRNA transcriptional levels in AA rat lymph nodes. The study on PK-PD model showed correlations between inflammatory factors and blood concentration of T. wilfordii. T. wilfordii and its main active constituent tripterine could show the inflammatory effect and treat RA by inhibiting IL-17 cytokine.
