The prognosis of gastric cancer is significantly associated with the disease stage,early diagnosis of gastric cancer is the key to extend the survival time of patients. Nowadays,gastroscopy combined with gastric mucosa biopsy is the most important method to detect early gastric cancer in clinical practice. However,the detection rate is low and requiring the endoscopists to learn the endoscopic morphological characteristics of early gastric cancer,which will help them to find out suspicious cancerous lesions and perform effective biopsy. This article reviewed the morphological risk factors of early gastric cancer under white light endoscopy,so as to provide endoscopists with the capability for diagnosis of early gastric cancer.

MRI and ultrasound technique have improved the diagnosis of glioblastoma and increased clinical value for themselves.Superselective intravascular perfusion chemotherapy/radiotherapy bring less damage,more local effectiveness and less adverse reactions,presenting bright future with involvement of anti-angiogenesis.Mechanisms of drug effect and recurrence of glioblastoma should be put in more emphasis for research work.Reducing diagnostic cost,promoting veracity and reliability of new techniques and intensifying the combination of Superselective intravascular perfusion and chemotherapeutic drugs will provide important significance for researches in the near future.(J Intervent Radiol,2007,16:284-286)

Selective salpingogram(SSG)and hysterosalpingography(HSG)have achieved fairly reliable diagnostic value. SSG and transcervical fallopian tube recanalization(T-FTR)possess rather credible therapeutic value,long-term effect and low risk. Recanalization rate and pregnancy rate,combining with the measurement of tubal perfusion pressures(TPP)and development of ultrasonic technology,can evaluate the therapeutic effect and safety more generally and objectively. Researches in the future should lay emphasis on developing non-radiologic technique,promoting diagnostic veracity,reducing side effects,and establishing randomly control trials together with consolidating the standardized evaluation criteria.(J Intervent Radiol,2007,16: 714-717)

This article reports a preliminary observation oh the growth of cercarial embryo of S.japonicum in defined medium cultivated one week in vitro. When extract of head-foot tissue of Oncomelania hupensis was added to the medium contained 1/2 RPMI 1640, the length of cercarial embryo increased. While liver extract of the snail was added to the same medium, the growth was inhibited.It seemed that the extract of snail liver tissue might be poisonous to the cercarial embryo.

Aim To investigate the effect of chlorogen-ic acid,caffeic acid,and ferulic acid on expression of molecules related with inflammatory response of HMECs induced by activated complement alternative pathway.Methods CVF was used to activate the al-ternative pathway of serum complement.After exposure of HMECs to activate complement for various times, supernatant of cell culture was removed and assayed for content of ICAM-1,IL-6,IL-8,t-PA,and PAI-1 u-sing ELISA kits.The expression of the above mole-cules induced by activated complement was measured after HMECs were pre-treated with 50,100,250 μmol ·L-1 of CGA,CA,and FA.Results After HMECs were exposed to the product of the activated comple-ment alternative pathway,the expression of ICAM-1 , IL-6,IL-8,t-PA,and PAI-1 was up-regulated.The expression of ICAM-1,IL-6,IL-8,t-PA,and PAI-1 was down-regulated by various concentrations of CGA, CA,and FA.ICAM-1 and IL-8 were inhibited most significantly in all molecules mentioned above.CA ex-hibited the best intervention effect,followed by FA. Conclusion Certain concentration of CGA,CA,and FA can inhibit the expression of ICAM-1,IL-6,IL-8, t-PA,and PAI-1 in HMECs induced by the activation of the alternative complement pathway,indicating that CGA,CA,and FA can inhibit inflammatory response of HMECs.

OBJECTIVETo observe the clinical efficacy difference on vegetative state in children between acupoint injection combined with plum-blossom needle and western medication based on basic treatment.

METHODSForty-eight children of vegetative state were randomized into an observation group and a control group, 24 cases in each one. On the basis of the treatment of transcranial magnetic stimulation apparatus, balancing treatment apparatus and massage, the acupoint injection and tapping method with plum-blossom needle were adopted in the observation group, in which Xingnaojing injection, mouse nerve growth factor (mNGF) injection, monosialotetrahexosylganglioside sodium injection (MSI), compound Danshen injection were divided in 6 pairs and were injected respectively in Baihui (GV 20), Yongquan (KI 1), Fengfu (GV 16), Yamen (GV 15) and the others, 0.5 mL in each acupoint, once a day for continuous 10 days. Additionally, the tapping method with plum-blossom needle was used on the Governor Vessel and Jiaji (EX-B 2) on the back. In the control group, the intravenous infusion was adopted with citicoline sodium injection, mannitol injection and dexamethasone injection. The treatment was given once a day, 20 days of treatment made one session and totally 3 sessions were required in the two groups. The clinical efficacy, the vegetative state score and the mean curing time were observed after 20 days, 40 days and 60 days of treatment between the two groups.

RESULTSThe effective rates were 58.3% (14/24), 70.8% (17/24) and 79.2% (19/24) in 20 days, 40 days and 60 days of treatment in the observation group and 20.8% (5/24), 45.8% (11/24) and 58.3% (14/24) in the control group respectively. The efficacy in the observation group was superior to those in the control group (P < 0.01, P < 0.05). The vegetative state score was improved apparently after 20 days, 40 days and 60 days of treatment as compared with those before treatment separately (all P < 0.05). It was improved obviously at the each time point after treatment in the observation group as compared with that in the control group (3.34 +/- 2.41 vs 2.64 +/- 11.56, 6.20 +/- 1.46 vs 4.34 +/- 1.64, 11.26 +/- 2.63 vs 8.75 +/- 2.18, all P < 0.05). The mean curing time was (45.67 +/- 16.24) days in the observation group, which was shorter apparently than that of (55.34 +/- 4.57) days in the control group (P < 0.05).

CONCLUSIONBased on basic treatment acupoint injection combined with tapping method of plum-blossom needle achieve the reliable efficacy on vegetative state in children.
