Through expounding the definition of appreciate inquire,this paper discussed its principles when usedin medical humanities education including constructionism,simultaneity,poetry,preconception and optimism.Guided by optimistic themes,the benign development of medical humanistic education was realized by 4D circulation mode (discovery,dream,design,andrealization) of appreciative inquiry summit talks.

Poor communication between medical staff and patients is the main cause of medical disputes,and the clear emotional recognition and reasonable response of the patient needs psychology training and practice.Balint groups can create a good support environment and is an effective way to improve the communication ability and professional growth for medical staff.

Due to the shortcomings of traditional medical professionalism education,coupled with the impact of the reality,medical students' professional spirit produced some phenomenon in clinical practice such as weak professional faith,lack of professional value,poor career cognitive and so on.If medical professionalism education wants to make mental shaping function in medical students who are in the clinical practice,the traditional classroom teaching must be combined with Internet technology and thinking.On the one hand,Internet renovation must be applied to teaching system of systematic classroom teaching,teaching content of practicality,and extension of classroom,and so on.On the other hand,it should vigorously explore new way of Internet learning such as Moocs,micro-course online video,Network teaching center platform,live courses,and so forth.At the same time,it should pay attention to the recessive educational form,establish a perfect evaluation mechanism,attaches great importance to the subjectivity of entity class teaching and the combination of Internet in the process,and explore the Internet plus mode of medical professionalism education together.

OBJECTIVETo investigate the effect of 8-aminolevulinic acid (ALA) photodynamic therapy (PDT) on the cell proliferation, apoptosis and collagen secretion in keloid fibroblasts and to provide the theoretical base for ALA-PDT treatment of keloids.

METHODSFibroblasts from keloid patients were cultured to the third generation in vitro and incubated in 0, 1, 3, 6, 9 mmol/L of δ-aminolevulinic acid for 3 h in the darkness. Then they were exposed to 635 nm wavelength red light ( 30 J/cm2 ) and continued incubation 24 h after irradiation. CCK-8 assay was used to detect proliferation inhibition rate of fibroblasts. The content of hydroxyproline was measured by colorimetric method. The expression of p-Akt and programmed cell death 4 ( PDCD4) were detected by Western blot.

RESULTSThe inhibition rate of keloid fibroblasts were respectively 0, (8.30 ± 1.01)%, (29.48 ± 3.27)%, (52.01 ± 5.34)%, (79.99 ± 5.85)% with the presence of difference concentrations (0, 1, 3, 6, 9 mmol/L) of ALA. The content of hydroxyproline were respectively (9.540 0 ± 0.352 42), (6.242 5 ± 0.224 85 ), (5.107 5 ± 0.534 88), (3.490 0 ± 0.623 48), (2.945 0 ± 0.514 10) μg/mg. The relative expression of p-Akt were respectively 1, 0.75 ± 0.12, 0.52 ± 0.14, 0.41 ± 0.18, 0.32 ± 0.09. The relative expression of PDCD4 were respectively 1, 1.18 ± 0.19, 1.51 ± 0.22, 0.15 ± 0.30, 2.44 ± 0.22. The difference was statistically significant when compared the group of 1, 3, 6, 9 mmol/L with 0 mmol/L (P < 0.05).

CONCLUSIONSIn concentration within the range of 1-9 mmol/L, ALA could inhibit the proliferation of fibroblasts significantly, promote fibroblasts apoptosis and reduce the content of hydroxyproline in a dose-dependent manner, indicating that 8-aminolevulinic acid photodynamic therapy may be a potential treatment for keloid.

Objective:To study the accessibility and the effect of group counseling which aim at the internet-dependence college students in China.Methods:According to the internet dependence standard which was established in the author's former research, chose 24 internet dependence students from Tsinghua University and JiLi University as the experimental group, and another 24 students as the control group.The experimental group and the control group had no difference in the scores of adapted CIAS-R before group counseling.There were a pre-test, a post-test and a tracing-test separately set when the group counseling was started, finished, and had a period of 6 weeks after it was finished.Results:In the post-test and tracing-test, the scores of adapted CIAS-R of experimental group were significantly lower than those of the control group(39.5?8.1/46.4?6.0,F=11.38,P

Isokinetic training, as a technique of orthopaedic rehabilitation, is a new and valuable method in evaluation of muscle function and in training muscle strength. It has higher accuracy and reproducibility in evaluation of muscle function. When isokinetic training of muscle strength is done, kinetic velocity is fixed beforehand in the dynamic instrument so that the resistance matches the actual force applied by the individual. The resistance maintains the maximum throughout the range of motion and produces the greatest muscle strength. As a result, the isokinetic muscle strength is effective and safe in the orthopaedic rehabilitation.

Objective To investigate the expression and significance of intermedin (IMD) and its.receptors CRLR,RAMP1,RAMP2 and RAMP3 in cancer tissues of patients with non-small cell lung cancer.Methods The mRNA gene expressions of IMD,CRLR,RAMP1,RAMP2 and RAMP3 were detected by realtime quantitative RT-PCR in cancerous and para-cancerous tissues from 27 patients with lung cancer.Results Real-time quantitative PCR detection results showed that the expression of IMD,CRLR,RAMP1,RAMP2 and RAMP3 in cancer tissues were [(59±7.9)×10-8,(96±2.7)×10-6,(29±3.9)×10-9,(14±2.6)×10-6,(65±1.1)×10-6]which were higher than those in adjacent tissues[(40±4.7)×10-10,(21 ±3.9)×10-6,(53±7.8)×10-10,(64±1.9)×10-8,(36±1.3)×10-9] to some extent (all P ＜ 0.05); the higher expression of RAMP3 was found is higher expressions than RAMP1 and RAMP2 in cancer tissues (all P ＜ 0.05).Conclusion The expressions of IMD and its receptors in cancer tissues are higher than those in paracancerous tissues.IMD may play an important role in the development of cancer by activate RAMP3 which is the most high expressed receptor in cancer tissues.Therefore,it might be helpful for the investigation of new gene thereapy in non-small cell lung cancer.

Objective To investigate the incidence of urological malignancy in renal allograft recipients and explore the mechanism of increased incidence in China and the management. Methods A retrospective study was performed on 22 patients with urological malignancy in renal allograft recipients between 1978 and 2010. Results Twenty-two cases of urological malignancy were diagnosed by pathologic evidence, including 9 cases of transitional cell carcinoma (TCC) of bladder, 1 case of squamous cell carcinoma of bladder, 1 case of adenocarcinoma of bladder, 1 case of TCC of pelvis, 1 case of TCC of bladder and pelvis, 1 case of TCC of ureter complicated with adenocarcinoma of bladder, 2 cases of TCC of ureter, 2 cases of TCC of ureter and bladder, 3 cases of clear cell carcinoma of kidney, and 1 case of undifferentiated carcinoma of kidney. All the malignancies belonged to native organs. All the patients suffering bladder cancer had normal function of allograft. Five patients with TCC of pelvis or ureter survived and 2 cases died early after operation. All the patients suffering renal carcinoma deceased within 6 months after diagnosis. One-year survival rate was 73. 7 % after the diagnosis of urological malignancy. Conclusion Urological malignancy ranked highest in malignancy in renal allograft recipients, and rare pathological types of urological malignancy in non-renal allograft recipients are often demonstrated. The strategy of treatment should take consideration of the relationship between the usage of immunosupressive agents and the preservation of allograft function. It is critical for the therapy of malignancies to possess satisfactory allograft function. The prognosis of renal cell carcinoma is poor.
