Observe and study the morphological changes and effects on yoleperoxidase (MPO) of traditional Chinese medical complex Intestine-clearing Suppository (ICS) in preventing and treating ulcerative colitis (UC).Method.. Divide the experimental rats randomly into 6 groups, i.e., blank, salicylazosulfapyridine (SASP), model, high, middle and low dosage of ICS, except the blank group, makeother rats experimental UC model with albumen immunologic method of rabbit colon mucosa, further divide them randomly into 2 experimental groups, i. e. , prevention and treatment, afterwards at 2nd~21st day, give prevention group the medicine, 22nd~35th day, treatment group, then decapitate them and take the colon tissue, and observe it morphologically under optical microscope, measure active MPO, analyse statastic results. Result: Through general morphological observation ,we found there were serious congestion ,edema, mucosa erosion, many large ulcers in the rats of model group; less serious mucosa erosion and quantity of ulcers in SASP and low-dosage ICS groups: small ulcers, not serious mucosa erosion, low degree of congestion and edema in high-and middle-dosage ICS groups; the scores of inflammatory injury of ICS groups were markedly lower than that of model (P<0. 01), meanwhile, the preventive and reating effectiveness of high-and middle-dosage groups was better than that of SASP (P<0.05). Under the optical microscope, there were large area of mucosa coloboma in the rats of model group, the ulcer penetrated to muscular layer and serous coat; in SASP group and low-dosage ICS group, there were erosive mucosa and inflammatory cell infiltration, granulation on the base; in middle-and high-dosage groups, large part of colon mucosa recovered, granulation formed on the base, ulcers were obviously less than that in model group (P <<0.01); there had marked difference compared with that in SASP group (P<0.05). The MPO active values of high-and middle-dosage groups were markedly lower than that of model group (P < 0.01). Conclusion: Traditional Chinese complex ICS had good prevention and treatment to rats UC, itseffectiveness was positively correlated with dosage and better than that of SASP suppository.

Purpose:To study the significance of resecting the lymph nodes adjacent to the recurrent laryngeal nerve in the operation on cNo thyroid papillary carcinoma,and its value inselecting the fashion of operation .Methods:Reviewing the clinical-pathological material of 186 cases of cNo thyroid papillarycary cinoma,and analyzing the relationship between lymph nodes adjacent to the recurrent laryngeal nerve and lateral cervical nodes metastasis. Results:Of 186 cases of cNo thyroid papillary cacinoma,there were 42.5% (79/186) with metastatic lymph nodes adjacent to the recurrent laryngeal nerve,63.2% of which had lateral cervical nodes or distant metastasis,while only 8 cases had metastasis in the negative group. Conclusions:The thyroid papillary carcinoma with metastatic nodes adjacent to the recurrent laryngeal nerve means there is a higher chance of metastasis in regions of the neck. Resecting the lymph nodes adjacent to the recurrent laryngeal nerve and frozed pathological examination can be a basis to determine whether redical neck dissection should be performed.

Aim This study was designed to investigate the effects of pravastatin,a potent 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor,on vascular smooth muscle cells (VSMCs) proliferation and leukocyte-endothelial cell adhesion induced by lysophosphatidylcholine (LPC).Methods Cultured VSMCs from rabbit thoracic aorta were incubated with various concentrations of LPC in the absence or presence of different concentrations of pravastatin. MTT was used to evaluate the proliferation of VSMCs. We determined the effects of LPC and pravastatin on neutrophil K562 adhesion to endothelial cells ECV304 by directly counting non-adhesive K562 cells.Results Incubation of VSMCs with LPC (1~10 ?mol?L -1) stimulated proliferation of VSMCs in a time- and dose-dependent manner,while pravastatin (0.3~1 mmol?L -1) treatment prevented the proliferation of VSMCs caused by LPC. Moreover, incubation of ECV304 with 3 ?mol ? L -1 LPC for 12 h significantly enhanced K562 cells adhesion to endothelial cells, whereas pretreatment with pravastatin reduced leukocyte-endothelial cell adhesion. Conclusion These results suggest that pravastatin can antagonize the effects of VSMCs proliferation and leukocyte-endothelial cell adhesion induced by LPC.

In the trends of large-scale brain research projects around the world, the China Brain Project aims to promote the understanding of the basic principles of the brain, and use the basic research of neuroscience to serve some urgent social and economic needs at the same time.As we approach the launch of this effort aimed at revolutionizing our understanding of cognitive principles of the brain, early diagnoses of brain diseases and brain-like intelligence technologies, it is timely to review the new progress in recent international brain research projects, and the deployment and future trajectory of neuroscience research in China.

Objective To explore the efficacy of tentorium cerebelli hiatus incision for treatment of severe brain injury complicated with tentorial herniation. Methods Tentorium cerebelli hiatus incision was performed in 38 patients of severe brain injury with secondary brain stem damage resulted from tentorial herniation after intracranial hematoma evacuation and bone flap craniotomy decompression. The changes of four sides cistern, ambient cistern and interpeduncular cistern before and after operation were observed. Results There was a siginificant difference in the appearance ratio of four sides cistern, ambient cistern and interpeduncular cistern between the preoperation and postoperation(P

Objective To explore the changes and clinical significance of plasma tissue factor pathway (TFP) levels during the onset of acute ischemic cardiac and cerebral vessel disease. Methods The study population consisted of 69 patients with AMI and 71 with AICS as well as 50 age-matched healthy volunteers. Blood samples were obtained during the onset period of AMI and AICS. Tissue factor (TF) and tissue factor pathway inhibitor (TFPI) activity in plasma were assayed with the chromogenic assay, Plasma TF and TFPI antigen were measured with ELISA, Plasma FⅦ coagulation activity (FⅦ:C) was developed in the one- stage system. Plasma FⅦa was determined by soluble TF assay, plasma prothrombin (FII) and fibrinogen (Fbg) were measured by one-stage amidolytic assay and thrombin time (TT) respectively. Results In the AMI group, compared with the control group, plasma TF activities and antigens, TFPI activities and antigens as well as FⅦa were significantly higher(all P0.05), plasma FII and Fbg were also remarkably increased (both P0.05). Conclusion The initiation of TF pathway would be associated with the onset of AMI and AIS, but the changes of TF, TFPI, FⅦ:C and Fbg in AMI are different from those in AICS, endothelial dysfunction and the blood is in hypercoagulable state.
