Objective To study the diagnostic value of double-balloon endoscopy (DBE) and capsule endoscopy (CE) for small intestinal bleeding. Methods Overall detection rates of small intestinal bleeding with DBE, CE and the whole alimentary tract barium meal were compared. Positive rates of bleeding detection with DBE and CE were compared within the same patients. Influence of CE on one-procedure rate of DBE was analyzed. Results In 105 cases of small intestine bleeding, DBE detected 24 cases of Crohn's disease, 15 adenocarcinoma, 12 chronic nonspecific inflammation, 10 small intestinal ulcer of unknown reason, 8 entero-mesenchymoma, 8 polypus, 6 vascular deformation hemorrhage, 5 ancylostomiasis, 5 Mechel's diverticula ( including multiple diverticula), 3 lymphoma and 9 of no evident abnormalities. The positive detection rate of DBE is 91.4% (96/105). Disease detection rates of CE and whole alimentary tract barium meal were 75.0% (30/40) and 33.3% (25/75), respectively. The one-procedure rate of DBE is 90% (36/40) based on CE results, but it was only 69. 2% (45/65) according to clinic features and the whole alimentary tract barium meal. Conclusion The main causes of small intestinal bleeding are benign ulcers (including Crohn's disease) and tumor, as well as chronic inflammation. Polyps, vascular deformation, parasitosis, Mechel's diverticulum and lymphoma are the secondary causes.DBE is superior to CE in diagnosis of small intestine bleeding, but CE can increase the one-procedure rate of DBE.

The stable and controllable quality of decoction pieces is an important factor to ensure the efficacy of clinical medicine. Considering the dilemma that the existing standardization of processing mode cannot effectively eliminate the variability of quality raw ingredients, and ensure the stability between different batches, we first propose a new strategy for Chinese medicine processing technologies that coupled with individuation processed and cybernetics. In order to explain this thinking, an individual study case about different grades aconite is provided. We hope this strategy could better serve for clinical medicine, and promote the inheritance and innovation of Chinese medicine processing skills and theories.

Objective To detect levels of IL - 4 and INF - ? in induced sputum dynamically in children with mycnplasma pneamo-niae pneumonia( MPP), and to analyze the function of Th1 /Th2 cell factor immune response in the genesis and development of MPP, so as to evaluate the clinical value of induced sputum method in MPP research. Methods There were 38 cases who were diagnoses as MPP using 3% high osmotic pressure of saline water to ultrasonic atomizing inhalation for inducing sputum. ELISA was used to detect IL-4 and INF-?. Results The content of IL-4 in acute stage was higher than that in convalescence stage in induced sputum of MPP children. Severe stage was higher than mild stage. However, the comparison between acute and convalescence stage didn't have statistics difference in the content of INF-?, neither did the comparison between severe and mild stage. IL- 4/INF- ? in acute stage was higher than that in convalescence stage. Severe stage was higher than mild stage. In convalescence stage, the comparison of INF - ?, IL - 4, IL - 4/INF - ? between the severe and the mild didn' t have statistic significance. Conclusions IL-4 and INF - ? have participated in the monogenesis of MPP. The disequilibria of Th1 /Fh2 is existed in MPP and Th2 reaction predominates. So induced sputum analysis can be a better way to judge the light or heavy press degree of MPP practically, conveniently and sensitively.

OBJECTIVETo investigate the effect of curcumin on the injury in hippocampal neurons and the expression of regulated upon activation nonnal T-cell expressed and secreted (RANTES) in hippocamp during cerebral ischemia/reperfusion (I/R) in rats with spontaneous hypertension (SH).
METHODSMale Wistar-Kyoto (WKY) rats and spontaneous hypertension rats (SHR) were randomly divided into five groups (n = 6): sham group (W-Sham and S-Sham group), ischemia/reperfusion group (W-/R and S/R group), curcumin group (S-Cur group) . Each group was splitted into 5 subgroups of 3 h,12 h, 1 d, 3 d and 7 d according to the time interval before reperfusion. Global brain ischemia/reperfusion model was established by 4-VO method. Hematoxylin-eosin staining (HE staining) was used to observe the vertebral cell morphology in hippocampal CA1 region. Nissl staining was applied to detect the average density of cone cells in hippocampal CA1 region. The expression of RANTES in hippocamp was determined by ELISA. The behavior of the rats was evaluated at 7 days after reperfusion. Results: Compared with the sham group rats, the ability of learning and memory was significantly decreased in ischemia/reperfusion group rats, the number of injured neurons were greatly elevated , the protein expression levels of RANTES was significantly increased (P < 0.05). Compared with W-I/R group rats, the ability of learning and memory in S-I/R group rats was greatly reduced, the number of injured neurons increased extremely, the protein expression level of RANTES was significantly enhanced( P <0.05). The number of injured neurons declined significantly in S-Cur group rats, the ability to learn and remember of these rats was improved and the RANTES protein content decreased significantly (P < 0.05).
CONCLUSIONSHR are more susceptible to ischemia/reperfusion induced hippocampal neuronal injury which may be improved by curcu min. Its underlying mechanism is possibly associated with the inhibition of RANTES protein expression level.

Pericellular matrix (PCM) is a narrow tissue region surrounding chondrocytes, which "chondron" with its enclosed cells. A number of studies suggested that PCM is rich in proteoglycans, collagen and fibronectin, and plays an important role in regulating microenvironment of chondrocytes. Direct measures of PCM properties through micropipette aspiration technique showed that PCM was different from mechanical property of chondrocytes and nature extracellular matrix. However, the function of PCM is not clear, and need further study.

Objective To discuss the optimal radiation dose in the treatment of the late course accelerated hyperfractionation(LCAH) radiotherapy for esophageal carcinoma by using two different treatment doses,focusing on the difference of the short term results,local control rates,treatment tolerance and long term survival rates between the two groups.Methods One hundred patients with esophageal carcinoma were randomly divided by the envelope method into two groups:the 60Gy group and the 75Gy group.Patients in 60Gy group received conventional fraction radiation for the first 3 weeks,and then hyperfractionation radiation(1.5Gy per fraction,two fractions a day with 6 hour interval,10 fractions per week) to the total dose of 60Gy/35 fractions/5 weeks.The radiation schedule of the 75Gy group was the same as the 60Gy group: conventional fractionation of radiation for the first 3 weeks and then hyperfractionation radiation for the rest 3 weeks to the total dose of 75Gy/45 fractions/6 weeks.Results There was no significant difference between the two groups in short term results.The 1-,3-,5-year local control rates were 86%,42%,32% in 60Gy group and 88%,52%,48% in 75Gy group,respectively.The 1-,3-,5-year survival rates were 86%,40%, 28% in 60Gy group and 72%,34%,16% in 75Gy group,with no significant difference(P= 0.283).The median survival time was 25 months for the 60Gy group and 19 months for the 75Gy group.Patients suffered from heavy radiation-induced esophagitis in the 75Gy group were significantly more than those in the 60Gy group(28% vs 10%,P= 0.022).But it was similar for patients who died of side effects in the two groups.Conclusions It is not suitable to pursue high dose in treating esophageal carcinoma with late course accelerated hyperfractionation radiotherapy as high incidence of side effects are unadvoidable if the dose is increased without changing the radiation fields and techniques.When escalating the dose to the esophagus,the radiated lung volume as well as the other normal tissues should be first subjected to meticulous and careful consideration.
