Objective To compare and evaluate the effect of PBL in clinical teaching of Pediatrics.Methods Among students of Grade 2002 in our university,two types of PBL,pre-learning and case-discussion,were used in their clinical learning of Pediatrics. And then,their effects were evaluated and compared with those of traditional learning method.Results More than 60% of the students agreed with PBL methods,and they considered PBL favorable to practice scientific logical thinking of clinical affairs,to increase their capabilities of learning,oral expression,communication and cooperation.The teachers agreed with PBL methods too for the better learning effect resulting from PBL.Conclusion PBL fits the needs of medical learning reformation.To train new type of doctors in century 21st,it is necessary to use kinds of new learning methods,including PBL methods and standardized patient (SP)in clinical teaching.

Objective To explore the role of intercellular adhesion molecule-1(ICAM-1)and lym- phocyte function-associated antigen-I(LFA-1)in the pathogenesis of Sjgren's syndrome(SS)and provide a theoretical basis for clinical therapy.Methods Immunohistochemical method was used to detect these two cellular adhesion molecules in labial salivary glands of primary Sjgren's syndrome patients and 15 healthy controls.Semiquantitative analysis was performed by image analysis software.Results①In salivary gland samples,the expression of both ICAM-1 and LFA-1 was significantly higher compared to that of controls(P

Objective To establish the model of P2 peptide-induced experimental autoimmune neuritis(EAN)in rats and explore the roles of Th_1/Th_2 type eytokines in EAN.Methods Lewis rats were grouped into EAN rats and control rats.The EAN rats were immunized by injection into both hind footpads of inoculums containing 100 ?g or 200 ?g of P2_(57-81)peptide and FCA while the control rats were immunized with FCA only.Clinical scores were compared at the maximum of disease.Supernatant productions of IFN- ?, IL-4 and IL-10 secreted by lymphocytes and obtained on day 14 after the immunization were examined. Histopathological assessment of sciatic nerves was made.Results Peak clinical scores of P2_(57-81)200 ?g (3.6?0.3)group were significantly higher than P2_(57-81)100 ?g group(2.2?0.6,P

Objective To evaluate the effects of hydroxyapatite (HA) extensively-coated prosthesis on elderly patients undergoing hip arthroplasty.Methods From February 1997 to May 1999,96 patients Were treated with hydroxyapatite (HA) coated prosthesis and followed up for their hip arthroplasty.Their results were studied clinically and roentgengraphically to evaluate chiefly their Harris scores,complications and thigh pain.The survival of prosthesis was evaluated according to Kaplan-Meier methods.Results The 60 cases were followed up for eight years on average(range,sevon to nine years).Their mean Harris scores were improved from 42 preoperatively to 90 postoperatively.Fifty-eihgt cases felt no pain at their hip,but two did at their thigh.No radiolucent lines were observed.All the prostheses achieved bony stabilization and remolding.Conclusions HA coated prosthesis can achieve fine fixation,because it helps bone conduction,resists axial force and torsion,and reduces operative risks.

The paper analyzes proposing and development of the concept of information literacy of clinical nurses and its relations with evidence-based nursing, nursing scientific research and clinical nursing, summarizes current situation and main opinions on influ-encing factors of the study, summarizes the methods and strategies to enhance information literacy of the clinical nurses, and tells the main direction and key points of the study on information literacy of clinical nurses.

Objective:To observe the clinical effect of tuina plus foot bath with Chinese medicine for patients with diabetic foot (DF) in early stage.Methods:A total of 70 patients with early-stage DF were randomly allocated by the random number table into two groups,with 35 cases in each group.Patients in the control group received conventional medication,while patients in the observation group received tuina plus foot bath with Chinese medicine on the basis of conventional medication.The clinical efficacy was compared after 2 courses of treatment.Results:After treatment,intra-group comparisons of ankle-brachial index (ABI) showed statistical significance in both groups (both P＜0.05).The curative rate was 83.3％ in the observation group,with the total effective rate of 96.7％,versus 29.4％ and 76.5％ in the control group,respectively,and the between-group comparisons showed statistical significance (both P＜0.05),indicating a better effect in the observation group.Conclusion:Tuina plus foot bath with Chinese medicine has a good therapeutic effect for DF patients in early stage.

Objective To discuss existing problems in talent team construction; To provide evidence for the government to enact proper strategies based on the analysis of the current situation of TCM practitioners (assistants) distribution in China from quantity, quality and distribution equity. Methods The research is studied through conducting a descriptive analysis of TCM practitioners (assistants) from quantity, education, job titles, ages, and other basic conditions and changes. Gini coefficient was used to evaluate the distribution of TCM practitioners (assistants). Results The quantity of TCM practitioners (assistants) increased by 53.7% from 2010 to 2015. Concerning the quality of personnel, the ratio of the personnel with bachelors degree or above increased from 38.6% to 44.2%, and a slight increase was observed with the personnel with senior title. In terms of age structure, the proportion of the age of TCM practitioners (assistants) under 25 years old, 35 to 59 years old decreased, and the proportion of the age of TCM practitioners (assistants) above 60 years old, 25 to 34 years old increased. From the perspective of equity, there is a difference between the provincial-level administration of human resources distribution. The Gini coefficient as per population distribution was around 0.1, which indicated good equity. From the geographical area configuration, the Gini coefficient was approximately 0.58, which showed high level of disparity. Conclusion There are problems of insufficient quantity, low quality and distribution disparity among regions in TCM practitioners (assistant) in China.

Objective To investigate the effect of platelet-derived growth factor-D (PDGF-D) on the prostate cancer cells migration and its possible mechanism. Methods The expressions of PDGF-D in LNCaP and PC-3 cells were detected with western blot.PDGF-D siRNA was synthesized according to mRNA sequence of PDGF-D gene and was transfected into PC-3 cell.The cells were treated with PDGF-D and PDGF-D siRNA,the cell migration was examined by Boyden chamber migration assay.The expression changes of VEGF and MMP-9 mRNA were detected by RT-PCR. Results The results of western blot indicated that the PDGF-D protein expression level was lower in LNCaP cells (29.47 ± 1.68) than that in PC-3 cells (63.43 ±2.10),(P ＜ 0.05).PDGF-D siRNA could down-regulate the PDGF-D protein expression in the transfected group (35.19 ± 1.51).The exogenous PDGF-D could promote migration of LNCaP and PC-3cells,and up-regulate the expression of VEGF,MMP-9 mRNA in PC-3 cells (P ＜ 0.05,compared with control group).PDGF-D siRNA inhibited PC-3 cells' migration and decreased the level of VEGF,MMP-9mRNA expression (0.72 ± 0.09 vs 0.43 ± 0.18,0.65 ±0.07 vs 0.22 ± 0.08) (P ＜ 0.05). Conclusion PDGF-D is involved in the promotion of prostate cancer invasion and angiogenesis.
