[Objective] The paper tries to find out the ways and methods for cultivating medical students ’ humanistic quality. [Methods]By doing questionnaire survey among students who major in clinical medicine, Chinese medicine, science of acupuncture, rehabilitation, au-diological medicine, medical images, pharmacy and so on to analyse the present situation of medical students ’ humanities in Zhejiang Chinese Medical University, then to demonstrate that strengthening the education of the humanistic quality is necessary to the success of the medical students. [Results] Survey results show that the medical students are satisfied about the education of the humanistic quality scheduled by the Zhejiang Chinese Medical University, but there are still problems in the concepts, systems, measures, and so on. In face of these problems, the paper puts forward some strategies, such as changing concepts and ideas, establishing the modern medical educa-tion, based on the first class, developing the second classroom, to let the medical humanistic spirit throughout the physical teaching and the practice teaching.[Conclusions]The ways and methods from the paper are practical and feasible. The importance and necessity of them are obvious.

OBJECTIVE:To determine the concentration of Dermatan Sulfate,a new antithrombotic medicine in blood or urine by spectrophotometry.METHODS:In Britton Robinson buffer solution(pH=5.8),color fading reaction occurred when Dermatan sulfate combined with neutral red dye to form ionic associate.The reduction of absorbance of the system was positively correlated to dermatan sulfate concentration,with the maximum absorption wavelength at 526 nm.RESULTS:The linear range of dermatan sulfate was 0.18～4.0?g?mL~(-1)(r=0.999 1) with a detection limit of 0.054?g?m~(-1).The average recovery was 100.3%(RSD=1.2%),with RSD of dermatan sulfate at low,medium,and high concentrations at 2.9%, 1.5%,and 1.1%,respectively.The coexisting substances did no interference on the determination results.CONCLUSION: The method is simple,accurate,and sensitive with good methodological selectivity and it achieved satisfactory results in the determination of dermatan sulfate in blood or urine.

Purpose Accurate diagnosis of triangular fibrocartilage (TFC) tear is very important for treatment. MRI is most used for diagnosing TFC tear. This paper aims to evaluate MRI and MR arthrography (MRA) for diagnosing TFC tear by meta-analysis. Materials and Methods The articles were searched in the databases such as Wanfang, VIP, CNKI, Cochrane Library, Medline, Embase and PubMed. The QUADAS items were used to evaluate the quality of the included studies. Heterogeneity of the included articles was tested. The pooled weighted sensitivity and specificity of MRI and MRA in diagnosing TFC tear were calculated, and the pooled receiver operation curve was drawn. Results Fifteen articles met the inclusion criteria, 2 were Chinese articles and 13 were English articles. The subjects and methods of the articles were different and existed heterogeneity. The sensitivity and specificity of MRI for diagnosing TFC tear were 0.66 (95% CI 0.61-0.71) and 0.75 (95% CI 0.69-0.81), and those of MRA were 0.80 (95% CI 0.73-0.87) and 0.86 (95% CI 0.74-0.93). The area under curve and Q* index of SROC of MRI were 0.8566 and 0.7875, respectively. The area under curve and Q* index of SROC of MRA were 0.9123 and 0.8446, respectively. Conclusion The accuracy of TFC tear avulsion for MRA are higher than for MRI, when there is unclear of TFC avulsion using MRI, MRA can be used for diagnosis.

OBJECTIVE:To explore the effects of Haikangling Mixture on immunological function in immunosuppressed mice induced by cyclophosphamide. METHODS: Mice were given Haikangling Mixture intragastrically for 14d, and the level of hemolysin was determined by sheep erythrocyte (SRBC) immunization to exploer the influence of Haikangling on humoral immunity in mice; splenic lymphocytes were measured by MTT to observe the influence on cell immunity; the clearance of macrophage were measured by carbon particle clearance method to explore the influence on non-specificity immunity. RESULTS: The level of hemolysin, the cell reproductive activity, splenic lymphocytes and the phagotrophy of mononuclear macrophage were improved obviously by Haikangling Mixture in immunosuppressed mice induced by cyclophosphamide. CONCLUSION: Haikangling Mixture can enhance the immunological function in immunosuppressed mice induced by cyclophosphamide.

Objective To investigate causes and effects of medial meniscus extrusion in patients with knee osteoarthritis.Methods A total of 120 patients diagnosed as knee osteoarthritis between January 2011 and March 2012 were enrolled in this study,including 60 patients with medial meniscal extrusion confirmed by MRI (extrusion group) and other 60 patients without medial meniscal extrusion (control group).The extrusion distance of medial meniscus and tibiofemoral angle were measured on MRI.The correlation between tibiofemoral angle and extrusion distance were analyzed.The incidences of genu varum,medial meniscus injury and cartilage lesion of medial tibiofemoral joint were compared between two groups.The effect of medial meniscal extrusion on meniscus injury and effect of genu varum on meniscal extrusion were analyzed.Results In extrusion group,the extrusion distances of medial menisci ranged from 3.76 to 11.6 mm (average,8.3±1.79 mm); all patients had genu varum,and the tibiofemoral angle ranged from 174°to 181°(average,179.0°±2.2°); the incidence of medial meniscus injury was 50.0％ (30/60) in the anterior horn,93.3％ (56/60) in the body,and 93.3％ (56/60) in the posterior horn; the incidence of medial meniscus tear in the root of the posterior horn was 23.3％ (14/60); the incidences of cartilage degeneration in medial tibial plateau and medial femoral condyle both were 100％ (60/60); a significant negative correlation was observed between dimension of tibiofemoral angle and extrusion distance of medial meniscus.In control group,the extrusion distances of medial menisci ranged from 0 to 2.61 mm (average,0.57±0.80 mm); four patients had genu varum,and the tibiofemoral angle in all patients was 180°; the incidence of medial meniscus injury was 0 in the anterior horn,16.7％ (10/60) in the body,and 70.0％ (42/60) in the posterior horn; no medial meniscus tear was found in the root of the posterior horn; the incidence of cartilage degeneration was 26.7％(16/60) in medial tibial plateau and 30.0％ (18/60) in medial femoral condyle.The odd ratio of meniscus injury and the number of genu varum (extrusion group/control group) was 6.0 and 15.0,respectively.Compared with the control group,the incidences and severities of medial meniscus injury and cartilage lesion of medial tibiofemoral joint were higher in extrusion group.Conclusion Genu varum may be one cause of medial meniscal extrusion.Medial meniscal extrusion increases incidence of medial meniscus injury and has a significant influence on generation and development of osteoarthritis in medial tibiofemoral joint.

This study examined the effects of ursolic acid (UA) on the proliferation and apoptosis of a human ovarian cancer cell line, CAOV3. The CAOV3 cells were cultured in the RPMI 1640 media and treated with different concentrations of UA (0, 10, 20, 40 mumol/L). The proliferation rate of the CAOV3 cells was determined by MTT assay. The apoptosis rate was measured by flow cytometry. ERK activity was detected by immunoprecipitation and the expressions of p-ERK1/2, MKP-1, Bax and Bcl-2 by Western blotting. The results showed that the proliferation rate was significantly decreased in the cells treated with UA as compared with that in the non-treated cells (P<0.05). The intracellular ERK activity and p-ERK1/2 expression were also reduced in the UA-treated cells, while the MKP-1 expression was elevated. Moreover, the apoptosis was found in the CAOV3 cells exposed to UA; the Bax expression was increased and the Bcl-2 expression decreased. The apoptosis rate in the UA-treated cells was much higher than that in the non-treated cells (P<0.05). It is concluded that UA can inhibit the proliferation of CAOV3 cells by suppressing the ERK activity and the expression of p-ERK1/2. And it can also induce the apoptosis of the CAOV3 cells by up-regulating the Bax expression and down-regulating the Bcl-2 expression.
