Objective To analyze and discuss the effects of preserving the intercostobrachial nerve(ICBN)in modified radical mastectomy for breast cancer. Methods A total of 80 patients with breast cancer were randomly divided into the observation group and control group(n = 40 in each). The ICBN in the observation group were reserved and it was removed in the control group. Operation time,the number of lymph nodes,blood loss and complication rates were compared between groups. Two groups of patients were followed up for abnormal sensory function and relapse and metastasis. Results There were no differences in the operation time,the number of dissected lymph nodes and blood loss(P > 0. 05). There was no difference in complication rate(12. 50% vs 15. 00% )between the observation group and control group(P > 0. 05). There were significant differences in the incidence of abnormal sensory function at the first week(10. 00% vs 52. 50% ),the first month(5. 00% vs 47. 50% ),the third month(2. 50%vs 45. 50% ),the sixth month(2. 50% vs 37. 50% ),and the twelfth month(0. 00% vs 27. 50% )after op-eration between the observation group and control group(P < 0. 05). During the one-year follow-up peri-od,there was no relapse or metastasis. Conclusion Preserving ICBN in modified radical mastectomy can effectively reduce the incidence of abnormal sensory function of the upper limb.

To explore the effective ingredients and mechanism of Ligusticum wallichii in treating brain ischemia. Four brain ischemia-related target proteins were selected in the joint screening for the 45 component in L. wallichii reported in literatures based on molecular docking by reference to the corresponding drugs in the market. According to the docking results, multiple components in L. wallichii, such as phthalides, were superior to the corresponding drugs in the market, suggesting that they may be the major effective components in L. wallichii for treating brain ischemia. The method can be used to study the material base and molecular mechanism of traditional Chinese medicines.

Action mechanism and material base of compound Danshen dripping pills in treatment of carotid atherosclerosis were discussed based on gene expression profile and molecular fingerprint in this paper. First, gene expression profiles of atherosclerotic carotid artery tissues and histologically normal tissues in human body were collected, and were screened using significance analysis of microarray (SAM) to screen out differential gene expressions; then differential genes were analyzed by Gene Ontology (GO) analysis and KEGG pathway analysis; to avoid some genes with non-outstanding differential expression but biologically importance, Gene Set Enrichment Analysis (GSEA) were performed, and 7 chemical ingredients with higher negative enrichment score were obtained by Cmap method, implying that they could reversely regulate the gene expression profiles of pathological tissues; and last, based on the hypotheses that similar structures have similar activities, 336 ingredients of compound Danshen dripping pills were compared with 7 drug molecules in 2D molecular fingerprints method. The results showed that 147 differential genes including 60 up-regulated genes and 87 down regulated genes were screened out by SAM. And in GO analysis, Biological Process ( BP) is mainly concerned with biological adhesion, response to wounding and inflammatory response; Cellular Component (CC) is mainly concerned with extracellular region, extracellular space and plasma membrane; while Molecular Function (MF) is mainly concerned with antigen binding, metalloendopeptidase activity and peptide binding. KEGG pathway analysis is mainly concerned with JAK-STAT, RIG-I like receptor and PPAR signaling pathway. There were 10 compounds, such as hexadecane, with Tanimoto coefficients greater than 0.85, which implied that they may be the active ingredients (AIs) of compound Danshen dripping pills in treatment of carotid atherosclerosis (CAs). The present method can be applied to the research on material base and molecular action mechanism of TCM.

BACKGROUND:Animal experimental studies have confirmed that cell transplantation,neurotrophic factor infusion or transplantation as well as other methods can alter the local environment of injured spinal cord and promote its partial function recovery. OBJECTIVE:This study aimed to assess the clinical efficacy of olfactory ensheathing cell transplantation for the treatment of the sequel of myelitis,and to explore whether it would promote the recovery of the spinal cord function. DESIGN:A non-randomized self-control study. SETTING:Ward of Second Department of Surgery of Taian Disabled Soldiers Hospital of Shandong Province. PARTICIPANTS:Thirty-two patients with obsolete myelitis,who come from all over China and suffered from disease for 0.5 to 7 years,admitted to our hospital between June 2004 and July 2007 were recruited in this study.The involved patients,including 21 males and 11 females,were aged 5-48 years.Their neurological functions were not obviously improved after various conventional treatments and limb function exercise.Meanwhile,various sensorimotors and autonomic nerve functional impairments were left.Among the patients,18 suffered from acute viral myelitis,8 from acute purulent myelitis and 6 from tuberculous myelitis.After onset,they were all given large doses of radiosonde, dexamethasone,anti-inflammatory and immunomodulatory drugs and various neurotrophic drugs.Twenty-six patients presented complete injury and six patients incomplete injury.Informed consent of treatment was obtained from each patient.The therapeutic protocol was approved by the Ethics Committee of the hospital.Embryonic olfactory bulbs were harvested from aborted embryo,which was donated voluntarily by the patients or their relatives. METHODS:Cells were isolated from embryonic olfactory bulbs,cultured and purified for 7 to 14 days,and finally they were digested into single-cell suspension.Under the surgical miscroscope,the cells were transplanted onto the regions which were above or below the spinal cord injury site.Two weeks to 2 months postoperatively,neurological function of spinal cord was assessed by using the American Spinal Injury Association(ASIA)Scoring Standard formulated in 2000,and was compared to pre-operation function. MAIN OUTCOME MEASURES:①Sensory function change.②Motor function change. RESULTS:Half a year to 2 years after olfactory ensheathing cell transplantation,the sensory and motor functions of 32 patients were all obviously improved(motor function:55.72?10.50 vs.51.53?13.41;light touch:69.53?11.68 vs. 63.06?15.98;pain sense:69.50?12.20 vs.64.03?15.0,all P
