Problem based learning(PBL) pedagogy has been widely used in medical teaching process.But how to best use and develop PBL teaching,many universities try actively.According to PBL philosophy and the disciplines characteristics,the department of Pathophysiology in Central South University designed and carried out CPBL(Case and Problem Based Learning,CPBL) pedagogy.From the perspective of students,the authors have compared the CPBL pedagogy with PBL pedagogy in other academies,and make some positive recommendations.

Objective To analyze the clinical characteristics and prognostic factors of elderly patients with cytogenetically normal acute myeloid leukemia (CN-AML). Methods A total of 104 initial CN-AML patients were enrolled in this retrospective study. The clinical characteristics were collected and analyzed retrospectively. Factors affecting complete remission (CR) were analyzed by using chi square test. Univariate and multivariate analyses of prognostic factors were performed by using Kaplan-Meier and Cox hazard regression model respectively. Results After the first chemotherapy, 72 of 104 patients were able to be evaluated the efficacy, the CR rate was 38.9%(28/72) and total response rate was 55.6%(40/72). The white cell count<100 × 109/L and NPM1 mutation were related to a higher CR rate [59.4%(38/64) vs. 12.5%(1/8), 83.3%(10/12) vs. 36.4%(8/22), P<0.05]. Among 104 patients, the median overall survival (OS) was 6.9 months. Univariate analysis results demonstrated that age≥70 years, secondary AML, white cell count≥100×109/L, FLT3-ITD mutation, CD7 expression, achieving CR beyond 2 cycles of induction therapy and CCI score≥2 were influence factors on OS. In multivariable analysis, FLT3-ITD mutation (HR=7.61, 95%CI 1.80-32.11, P= 0.006) and achieving CR beyond 2 cycles of induction therapy (HR= 10.11, 95 % CI 2.38-43.03, P=0.002) were independent prognostic factors for OS in elderly patients with CN-AML. Conclusion The prognosis of elderly patients with CN-AML is the result of the combined effect of many factors, FLT3-ITD mutation and achieving CR beyond 2 cycles of induction therapy are independent prognostic factors in elderly patients with CN-AML.

Teaching clinics represent a unique form of outpatient training of resident physicians and serve as a crucial instrument and core component of standardized training of general practice residents. This article reviews the common model and innovations of teaching clinics of general practice in China, and analyzes their reported effectiveness in enhancing the capabilities of consultation of resident physicians, the teaching capabilities of general practice trainers, as well as satisfaction levels of involved participants. It outlines the challenges encountered in implementing teaching clinics, including inadequate teaching facilities and equipment, incomplete incentive system for teaching, difficulties in patient recruitment, and weaknesses in the teaching capabilities of trainers. To address these challenges, this article proposes corresponding strategies based on realistic needs, including the improvement of facilities and equipment in teaching clinics, the establishment of incentive systems for teaching clinics, the expansion of patient recruitment channels for teaching clinics, and the enhancement of training for trainers' teaching capabilities. This is envisaged to provide both theoretical bases and practical guidance for the effective execution and standardized development of teaching clinics in general practice residency training bases.

Objective: To analysis of the effect of strengthening management of dyslipidemia in community based on family doctor contracting service. Methods: In December 2014, 1267 cases patients with dyslipidemia aged over 18 years were selected from three community health service centers in Hangzhou, including 645 in intervention group (311 males and 334 females) and 622 in control group (307 males and 315 females). In the intervention group, the management of dyslipidemia in community was strengthened by graded follow-up and personalized diagnosis and treatment based on the contracted services of family doctors, while the control group adopted the general management of dyslipidemia in the community. After 12 months of intervention, the changes of lifestyle (smoking, drinking, body mass index, waist circumference), regularly taking lipid-regulating drugs, blood lipid, blood pressure, blood sugar levels and their control rates were compared by χ² test or t test before and after intervention between the intervention group and the control group. Non-conditional logistic regression analysis was used to analyze the influencing factors of blood lipid attainment. Results: Before intervention, there were no significant differences in gender, age, cardiovascular risk stratification, the levels of lipid and other metabolic indicators, lipid compliance rate between intervention group and control group (P> 0.05). After intervention, the intervention group improved in drinking, overweight,obesity, abdominal obesity, and the rate of regularly taking lipid-regulating drugs increased,compared with the control group, the difference was statistically significant (χ²=5.923,4.765,8.587,5.341, 5.654; all P<0.05). The levels of total cholesterol, triglyceride, low density lipoprotein cholesterol, body mass index, waist circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose, glycosylated hemoglobinin the intervention group were lower than those in the control group, the differences were statistically significant (t=-4.987,-3.207, -6.280, -3.339, -2.466, -4.052, -5.012, -2.865, -2.450; all P<0.05), while the HDL-C level in the intervention group was higher than that in the control group (t=2.294; P<0.05). The control rate of blood lipids, the control rate of blood pressure, and the combined control rates of blood lipid, blood pressure and blood sugar in the intervention group were higher than those in the control group, the differences were all significant (χ²=31.262,4.818,17.245; all P<0.05). Unconditional logistic regression analysis showed that family doctor contracted services (OR=1.961, 95%CI: 1.485-2.589), gender (OR=0.662, 95%CI: 0.471-0.930), smoking (OR=0.498, 95%CI: 0.332-0.745), obesity (OR=0.570, 95%CI: 0.359-0.904), hypertension (OR=0.353, 95%CI: 0.259-0.480), diabetes mellitus (OR=0.340, 95%CI: 0.239-0.483) was the influencing factor of blood lipid reaching the target (all P<0.05). Conclusion Intensive management of dyslipidemia in community based on family doctor's contracting service is helpful to improve the management effect of dyslipidemia.
