Basic cognition of TCM for human body includes three aspects:(1)Human body is an unify of form,Qi and sprit intrinsically;(2)Human is an unity composed of five solid organs in functions and structures;(3)Form,Qi,sprit and the Zang-and Fu-organs of human body connect together via channels and collaterals.The characteristics of TCM study methods are mainly trialistic nature of study objects,phenomenon analogy,functional leading nature of function and unify of the whole.

Fluorouracil,oxaliplatin and irinotecan、are generally accepted as the standard chemothera-peutic agents for metastatic colorectal cancer.In recent years,the research advances on metastatic colorectal cancer treatment focus on the combination between different active drugs,and try to search advisable combined therapy methods.Clinical trials suggest that ahemating regimen is effective and has lower toxicity which provides platform for further study of combined chemotherapy for metastatic colorectal cancer.

BACKGROUND:There are no unified methods to isolate,culture and amplify bone marrow mesenchymal stem cells(BMSCs) . Endothelial progenitor cells(EPCs) can be harvested by inducing peripheral blood or bone marrow mononuclear cells. However,the method of collecting bone marrow mononuclear cells is various,and the isolation efficiency is different. OBJECTIVE:To isolate and identify BMSCs and EPCs in vitro. DESIGN,TIME AND SETTING:The cytological in vitro study was performed at the Central Laboratory,First Affiliated Hospital,Anhui Medical University from October 2008 to February 2009. MATERIALS:Two clean healthy male Sprague Dawley rats were supplied by the Anhui Animal Center. METHODS:Rat bone marrow was extracted to harvest mononuclear cells by density gradient centrifugation. BMSCs were isolated by the differential adhesion. Following 48 hours of primary culture of BMSCs,non-adhered cells were collected and induced by EGM-2 complete medium supplemented with fetal bovine serum,vascular endothelial growth factor,fibroblast growth factor,insulin-like growth factor-1 and recombinant human epidermal growth factor. There were three groups:early adherence + common culture EPCs,twice adherence + induction culture EPCs,and rat mature aorta EPCs. Nitric oxide content was directly measured in the medium using nitrate reductase method. MAIN OUTCOME MEASURES:The following parameters were measured:in vitro culture of BMSCs and EPCs,and nitric oxide content in the medium. RESULTS:Primary culture of BMSCs was in a spindle-shape,within 24 hours the majority of cells were adherent,9-10 days up to 90% cells were confluent. Purified BMSCs were amplified and uniform,long spindle,with the passage cycle for 8 days. Flow cytometry detection showed that cells were CD34-,CD45-negative and CD105-positive. Second adherent of EPCs induced by 3 days culture showed colony formation following six days,appeared cord-like structure and microvessel-like growth at 8-10 days. At 2 weeks,the majority of cells were polygonal,colony-forming unit was interconnected,showing a typical "cobblestone"-like. At 7-10 days,cells were double stained DiI-acLDL and FITC-UEA-1. Flow cytometry showed Flk-1-positive and CD133-positive. Nitric oxide content was significantly higher in the culture medium compared with the ordinary cultured cells(P

Objective To investigate the feasibility,operation design and postoperative rehabilitation in ankylosing spondylitis patients with bilateral hips and knees bony ankylosis,who were operated on the 4 joints during one hospitalization period. Method Two operations were performed in one hospitalization period in three ankylosing spondylitis patients on the 2 hip joints and 2 knee joints respectively.One case,the left hip replacement was operated in the first operation,and the right hip and the double knees were operated in the second operation;the other two cases,unilateral hip and knee were operated in two operations respectively.Patients began to contract their lower limbs’ muscles initiatively after narcosis.The limbs were put on the CPM,the hips and knees were bent and extended repeatedly on the third day after operations.The patients began to leave bed and learned to walk 2 weeks after operations.They could walk 100 steps with aids when they leaft hospital. Result In six-month follow-up,the range of hip motion(degree)were 105?~145?(average 135?);the range of knee motion(degree)was 45?~60?(average 54?).The hip’ function score adopted Harris score system:the average of 83 and were all good;the knee’ function score adopted American Association of Knee Surgery score system in 1989:all were excellent except a good one(left knee of first case,the score was 74/75). Conclusion Performing operations on the 2 bony ankylosis hips and 2 bony ankylosis knees in the ankylosing spondylitis patients in one hospitalization period can shorten the treatment cycle,release the distress,and lighten the economic load,meanwhile it is convenient for operation and postoperative rehabilitation.It is better to do the unilateral hip and knee in a single operation.

(PHM)onexhaustedfatigueinmice.METHODS Micewereforcedtorun30minadayforconsecutive 18 d using the wheel running fatigue apparatus, and the speed was gradually increased from 10.2 m·min -1 to 12.6 m·min -1 .On d19,these animals were forced to run 60 min to establish an exhausted fatigue model.Every day,40 min before the run training,the animals were ig administered with PHM (140,280,560 mg·kg -1 )and modafinil (13 mg·kg -1 ).The number of electric shocks was recorded on d5,d9,d1 3,d1 7 and d1 9,respectively,and the body mass of each mouse was recorded daily.The levels of muscle glycogen (MG),liver glycogen (LG),serum urea nitrogen (SUN),serum lactic acid (SLA)and serum creatine kinase (CK)were detected by commercially available kits. RESULTS Duringthelastexhaustedrunningond19,thenumberofelectricshocksofthemodelgroup was markedly larger than that of the drug administration groups.When compared to the normal control group,the model group showed a significant decrease in the level of either MG or LG,but a significant increase in the level of either SUN or CK.The nu mber of electric shocks of the PHM in the moderate and high dose groups was 133 ±55 and 1 15 ±41 times,respectively,which was significantly smaller than that of the model group 240 ±89 (P<0.01 ).The levels of MG and LG of the PHM560 mg·kg -1 group were (1 .28 ±0.24)mg·g -1 and (40.9 ±1 0.2)mg·g -1 ,respectively,which were significantly higher than those of the model group〔MG:(0.91 ±0.26)mg·g -1 ,LG:(22.2 ±2.9)mg·g -1;P<0.01〕,and the levels of SUN,SLA and CK of this PHM group were (5.8 ±1 .3)mmol·L-1 ,(5.7 ±1 .7)mmol·L-1 and (0.6 ±0.2)kU·L-1 ,respectively,which were significantly lower than those of the model group 〔SUN:(7.5 ±2.1 )mmol·L-1 ,SLA:(7.1 ±1 .8)mmol·L-1 ,CK:(0.8 ±0.3)kU·L-1;P<0.05〕.The number of electric shocks of the modafinil group was also significantly smaller than that of the model group (P<0.01 ),but there were not any significant differences between the modafinil group and the model groupinthelevelsofMG,LG,SUN,SLAorCK.CONCLUSION ThisstudyshowsthatPHMcanhelp relieve fatigue,which might be associated with its abilities to increase the storeage of energy sources,to enhance the aerobic metabolis m,and to decrease the accu mulation of metabolic products.

Totally, 125 elderly inpatients with aspiration pneumonia (AP) were enrolled from departments of respiratory medicine and neurology at Zhongnan Hospital, Wuhan during June 2005 to October 2009 for analysis. Results showed that listlessness was manifested in 70 cases (56%), primary neurological illness in 80 cases (64%), 57 of them (46%) complicated with respiratory failure and 26 died with case-fatality of 21%. Main pathogen for them was Gram-negative bacillus, accounting for 57% of the total. Two kinds or more of antibiotics had ever been administered in 98 cases (78%), with an average length of antibiotics use for 28 days, ranging from one day to 128 days. Nasal feeding was instituted for those with choking over their feeding and coughing, and their inspired feeding was aspirated from the trachea or bronchi and lavished with bronchoscopy, with 38 cases by tracheal intubation, 26 by tracheotomy and 42 with artificial ventilation. Their average duration of hospital stay spanned 28 days with an average cost of 25 000 RMB yuan per capita, significantly higher than that for those with common pneumonia. In conclusion, clinical features of these elderly patients with AP were not so typical, most of them manifest severe, with lots of medical cost and bad prognosis.

Aim To investigate the neuroprotective effects of osthole(Ost)on the primary cultured cortical neurons transfected with APP595/596 gene and its underlying mechanism.Methods Neonatal mouse cortical neurons were transfected with APP595/596 gene to establish AD cell models for the further study.Then,the cell viability was detected by CCK-8 assay,and the leakage of lactate dehydrogenase(LDH)was assayed by LDH kit to evaluate the injury degree.Transferase-mediated nick end labeling(TUNEL)was used to evaluate the cell apoptosis.The expression of β-amyloid peptide(Aβ)and β-site APP cleaving enzyme 1(BACE1)was measured by immunofluorescence,while the miRNA-107 was measured by RT-PCR.Results Compared to model group,Ost could significantly improve the neurons viability,decrease the LDH release and prevent the apoptosis.Ost also inhibited the expression of Aβ and BACE1 at protein level,while enhanced the expression of miRNA-107 at gene level.Conclusion Ost plays a neuroprotective role in neurons transfected with APP595/596 gene in part through up-regulating miRNA-107.
