This paper discussed the connotation of Confucian benevolence and analyzed the Chinese traditional physician professionalism in view of the six aspects, which containedmedicine being humane artloyalty and for-bearancerespect for lifepractice medicine to save people, and compassion. Combining with the current situation of the development of the physicians, it analyzed the research values of Chinese traditional benevolence thought in the current physician professionalism construction:researching medicine painstakingly and making ardu-ous efforts to conquer medical problems;deeply understanding the philosophy ofloyalty and forbearance and re-garding patients as relatives;precious human life is priceless and establishing the lofty life values ofpeople-o-riented;practice medicine to save people and strengthening the social moral sense of responsibility;being con-siderate to patients and practicing medicine honestly.

Objective To study the platelets activation in patients with acute cerebral hemorrhage and its significance in perihematoma edema.Methods 33 patients with cerebral hemorrhage were treated with minimally invasive surgery.The volume of edema perihematoma was determined by CT technique before operation.The expressions of platelets CD62p and TSP in intracerebral hematoma fluid and venous blood were detected by flow cytometry(FCM).The correlation between the two variables was also analyzed.Results The expressions of platelets CD62p and TSP were higher in patients with acute cerebral hemorrhage than those in healthy individuals,and the expressions of platelets CD62p and TSP in intracerebral hematoma fluid were higher than those in venous blood.There were significant positive correlations between the expression levels of CD62p and TSP from the surface of platelets in hematoma and the edema size perihematoma(CD62p:r=0.4781,TSP:r=0.5183,all P

A comparative study of systemic lupus erythematosus in 39 male(MSLE) and 120 female (FSLE) patients was carried out. The results showed that, in MSLE, the mean age at the time of disease onset was similar to FSLE, and the clinical features were nearly the same as those in females, except that the first signs of MSLE were less complicated than those of FSLE, malar rash occurred less commonly in MSLE than in FSLE(P

Objective To explore the effects and mechanisms of urokinase-type plasminogen activator (uPA) on high glucose-induced rat mesangial cells proliferation and phenotype transformation. Methods Rat mesangial cells were cultured and incubated in media containing either 5 mmol/L D-glucose or 30 mmol/L D-glucose with or without addition of wortmannin, or uPA (105 U/L) for different time periods. At the end of the incubation period, mesangial cells proliferation was assessed by MTT assay and flow cytometric analysis. Cyclin-dependent kinase 2 (CDK2) and p27kip1 expression and activation of Akt were evaluated by Western blotting and Akt kinase assay respectively. Furthermore, the expression and distribution of α-SMA were detected with laser confocal microscopy. Results MTT assay and flow cytometric analysis demonstrated that high glucose induced mesangial cells proliferation (P＜0.05) and an incresed proportion of cells in G2/M+S stage after 24 h incubation (P＜0.01), which were attenuated by uPA or wortmannin (P＜0.01). High glucose induced the enhance of Akt activity after 3 h (P＜0.05), and the effect was inhibited by wortmannin or uPA (P＜0.01). High glucose did not alter CDK2 expression (P＞0.05),but significantly inhibited p27kip1 expression (P＜0.05), which was attenuated by wortmannin or uPA (P＜0.01). High glucose induced the up-regulation of α-SMA expression and perinucleus location in mesangial cells after 24 h (P＜0.01), which were alleviated by wortmannin or uPA (P＜0.01). Conclusion uPA up-regulates p27kip1 expression and counteracts high glucose-induced mesangial cells proliferation and phenotype transformation via blocking PI3K-Akt signaling pathway.

Objective To discuss the nursing countermeasures of common problems in patients with spinal fracture. Methods All patients received evidence- based nursing in on:ler to tackle problems such as pain, paralysis, pulmonary infection, pressure ulcer, urinary tract infection and deep vein thrombosis. Results No one complicated with pulmonary infection, pressure ulcer and deep vein thrombosis, 2 with lower limb swelling and 3 with urinary tract infection. Conclusions Evidence- based nursing is the base of clinic nursing. It can not only improve the quality of nursing and benefit patients,but also can expand the nurses' knowledge.

Objective To investigate clinical characteristics of smear- or culture-positive pulmonary tuberculosis (TB) in patients hospitalized at a general hospital to improve its diagnosis. Methods Clinical data of smear- or culture-positive pulmonary TB diagnosed in 50 patients hospitalized at Peking Union Medical College Hospital, Beijing during 2006 to 2009 were analyzed retrospectively. Results Seventeen (34%) of 50 cases of smear- or culture-positive pulmonary TB aged more than 60 years, with 30 males (32%), 16 retirees and nine farmers (18%). Their main symptoms included fever (80%), cough (94%) and sputum expectoration (92%), with elevated erythrocyte sedimentation rate (ESR) in 38 of 45 patients (84%). Chest X-ray examinations showed that lesions located mostly in the upper lobes or in both of the lungs diffusedly, with patchy infiltrations, nodular opacities and cavities. Acid-fast bacilli were demonstrated on sputum smear in 41 ( 82% ) and in specimens of six ( 12% ) cases obtained through bronchoscopy with brush or bronchoalveolar lavage fluid ( BALF), and M. Tuberculosis was cultured from sputum specimens in three (6%). Mean time interval between admission and diagnoses averaged 14 days.Conclusions Basic knowledge about prevention and control of pulmonary tuberculosis should be publicized comprehensively in general hospital keeping alert in its diagnosis with acid-fast staining for sputum smear as a routine test for patients with respiratory symptoms, and in some cases, bronchoscopy procedures ( brush or BALF) are reasonable options to improve its detection.

Objective To evaluate the effects of rehabilitation training on muscle strength and exercise toleranee in hemodialysis patients with muscle atrophy.Methods Nine hemodialysis patients with muscle atrophy because of end renal failure were recruited in this study. A structured exercise program(90 minutes a sedssion.3 sessions a week)was administered to all the subjects for 6 month.Immediately before and at the end of the exercise programme,the muscle strength of the lower limbs,the motor conduction velocity of the peroneal nerve and maximal oxygen consumption of the patients were examined. Results It was shown that all the patients had impaired exercise capacity,weakend muscle strength and slowed nerve conduction velocity before rehabilitation training.After the exercise programme,the patients' exercise capacity as reflected by the maximal oxygen consumption and exercise time was significantly increased.The muscle strength and the motor nerve conduction velocity were significantly increased.Conclusions Muscle atrophy in hemodialysis patients results in poor exercise tolerance, but rehabilitation exercise programme improves amyotrophy and therefore has beneficial effects on the patient's overall work performance.

[ ABSTRACT] AIM:To investigate the mechanism underlying breast cancer metastasis and to provide theoretical da-ta for studying the pathogenesis of breast cancer onset and development.METHODS: Human breast cancer MCF-7 cells were treated with different concentrations of furin inhibitorα1-PDX for 48 h.Wound healing assay and Transwell assay were applied to detect the migration and invasion abilities of the MCF-7 cells.The expression of cell migration-associated proteins, including membrane-type 1 matrix metalloproteinase ( MT1-MMP) , vascular endothelial growth factor ( VEGF)-C and VEGF-D, was determined by Western blotting.The protein levels of MMP2 and MMP9 in the supernatant were measured by ELISA. RESULTS:Compared with control group, 200 nmol/L of furin inhibitor exerted significant inhibitory effects on the cell mi-gration (P<0.05).The expression of cell migration-associated proteins MT1-MMP, VEGF-C and VEGF-D was significantly inhibited after treated withα1-PDX ( P<0.05 ) .Significant inhibitory effects of α1-PDX on the expression of MMP9 and MMP2 (P<0.05) in the supernatant were observed.CONCLUSION:Furin inhibitor suppresses the metastasis of MCF-7 cells via down-regulating the expression of MMPs and VEGFs.

Objective To observe the effect of isolating and harvesting the chondrocytes from rabbits rib cartilage with the method of three-step enzymatic digestion, and the biological characteristic of the isolated chondrocytes during cultivation in vitro to evaluate their biological activity. Methods The method of three-step enzymatic digestion was designed that the rib cartilage was digested one by one with 1 g/L trypsin and 1 g/L EDTA, 1 g/L hyaluronidase and 2 g/L collagenaseⅠ in the culture medium to isolate chondrocytes. The harvesting and viability rate of the primary chondrocytes were detected. During the passage cultivation in vitro, the changes of the chondrocyte shape and growth were observed, and the changes of the collagen typeⅠ and Ⅱ and aggrecan in the extracellular matrix were detected. Results ① The extracellular matrix of rib cartilage was completely dissolved by the three-step enzymatic digestion, and the chondrocytes were completely isolated from the solid matrix. The number of the harvested chondrocytes from every gram of wet cartilage was (4 295.7)?10~(4) on average,and their viability rate was 97.2% on average. ②The primary and first passage chondrocytes had triangle or multi-angle shape, and became elliptic shape at the growing confluence with the positive immunohistochemical staining of collagen type Ⅱ and the strong heterochromia to toluidine blue. The content of sulfate glycosaminoglycans(GAG) in the extracellular matrix of the primary passage cells was (80.61?11.40) ?g/cm~(2). The chondrocytes after the third passage gradually became spindle shape with the negative staining of collagen typeⅡ and the weak heterochromia to toluidine blue. The content of sulfate GAG of the fourth passage cells was (44.74?10.18) ?g/cm~(2). Conclusion ① The method of three-step enzymatic digestion can make the extracellular matix of rib cartilage to be completely degraded, and has advantages of the high efficiency of harvesting primary chondrocytes with high cellular viability rate and simple manipulation. ②The primary and first passage chondrocytes have fine biological activity.
