1.Morphological Risk Factors of Early Gastric Cancer under Endoscopy
Chinese Journal of Gastroenterology 2014;(9):566-569
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.

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)

Objective Cardiac valve replacement with cardiopulmonary bypass ( CPB ) can induce myocardial ischemia-reperfusion injury , which is bad for cardiac function recovery .The aim of the study was to evaluate the myocardial ischemia-reperfusion injury effect of breviscapine intravenously injected before CPB in patients undergoing cardiac valve replacement with CPB . Methods 40 patients scheduled for cardiac valve replacement were randomly divided into two groups :control group and breviscapine group ( n=20).Normal saline 15 mL and breviscapine 0.75 mg/kg was administered with pump within 30 mins after the induction of anesthesia in control group and breviscapine group respectively .Blood samples were taken from jugular vein at each of the five time points: before surgical incision (T0) and at 30mins, at 6, 12, 24h after aortic unclamping (T1-T4) for determination of plasma concentration of car-diac troponin-I (cTnI), creatine kinase isoenzyme (CK-MB) and superoxide dismutase (SOD). Results Compared with T0, the cTnI and CK-MB in both groups significantly increased at T 1-T4 and peaked at T 2 , the SOD in both groups significantly decreased at T 1-T4(P<0.05).Compared with control group, cTnI and CK-MB significantly decreased, while SOD activity significantly increased at T1-T4in breviscapine group (P<0.05). Conclusion The intravenous infusion of breviscapine 0.75 mg/kg before the staring of CPB can relieve myocardial ischemia-reperfusion injury in patients undergoing cardiac valve replacement with CPB , and the mechanism may be related to the anti-oxidative stress effect .

A further observation was conducted on the ultrastructure of mother sporccyst (Ms),daughter sporocyst in the brood chamber (b-Ds),migrating daughter sporccyst (mi-Es) and daughter sporocyst in the liver tissue (1-Ds) of Oncomelania hupensis by scanning and transmission electron microscopy.There are 5 points worthy of mention here,namely:(1)A special structure,microvilli polymerizing cisterna,is found on the tegument of 52-day-old Ms branche in all directions and a tubule-like structure is connected to the matrix of the tegument,The significance of this structure may be dealed with the metabolism and transport of the parasite.(2) The tegumental spines appear on 52-day-old Ms.(3) The function of multilaminated vesicle in the tegument of 1-Ds may be associated with the turning over of the surface coat of the larvae and the copatibiltiy between parasite and molluscan host.(4) Abundant ?-glycogen granules and mitochondria appear in the cytoplasm of parenchyma cell of brood chamber of Ms and Ds.It is proposed that the parenchymal cells not only served as the filling material,but also serve as the nursing cells for the regulation of asexual reproduction of the sporocysts.(5)The orientation of muscle fibers of the head of the mi-Ds and narrow node region of 1-Ds shows a well development of the inner longitudinal fibers adjacent to the outer circular muscle layer.They run anlero-posteriorly or vertically from the dorsal to the ventral.The pattern of muscle fibers may account for the activity of these regions of the parasite.(Figs 1-8)In short,the presentation of microvilli polymerizing cisterna,multilamilated vesicle,?-glycogen granules in parenchymal cell,the genesis of spine and the pattern of muscle fibers of the larval stage of schistosome might be helpful in understanding the asexual reproductive physiology of the parasite.

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.
