Objective To reform and assess the English curriculum for medical doctor-post-graduates based on the requirement analysis theory. Methods All of the medical doctor-postgradu-ates in grade 2012 of the Third Military Medical University were surveyed using questionnaires and face-to-face interviews on randomly chosen students,which collected information on the current Eng-lish skill levels,the requirements and the motivations of English learning,the satisfiable degree of English curriculum,and the outcomes of the curriculum reform. Statistical analysis methods were ap-plied in this study,especiallyχ22 test which was used to test the impact of current English levels on the requirements and motivations of English learning and the analysis results were applied to guide the curriculum reform and assessment. Results The questionnaires were handed out for twice,340 in total. Before and after the course setting,168 and 170 effective ones were got respectively. The first questionnaire showed the requirement of English learning wasn't influenced by the current English skill levels (P=0.329). That was to say 70.2%(118/168)of the surveyed students whether they were in level 4 or 6 all desired to improve English listening and speaking skills;and regard to English lear-ning motivations,publishing SCI papers,studying abroad,personal interest,or passing the course's exams accounted for 53.6%(90/168),24.4%(41/168),15.5%(26/168),6.5%(11/168)respec-tively,but relevant to their English levels (P=0.036). Regardless of their English levels,publishing SCI papers was the chief motivation of English learning. However,passing curriculum examinations as a motivation was more relevant to low-level students. The second survey also showed that 86.5%(147/170)students satisfied the setting of ‘listening and speaking’to ‘reading and writing’(2∶1) and 86 . 3%(145/168 )of students considered necessary to have a SCI dissertation writing course . However,once taking it,30.3%(44/145)out of the 86.3%(145/168)students expressed dissatisfac-tion to the course. In addition,about 48.8%(83/170)of students supported the tiered teaching model. Conclusions The requirement analysis technique is conducive to curriculum setting for medical doc-tor-postgraduates. However,the curriculum system needs to be optimized from the aspects of teaching methods,the tiered teaching model,and the teaching staff team. In particular,the cooperation be-tween English language teachers and medical major teachers should be strengthened in order to ap-proach an adequate and effective curriculum.

Objective To analyze and compare the clinical characteristics and therapeutic effects on pediatric patients with immune thrombocytopenia (ITP) among infants and children more than 3 years old.Methods The data of 1 015 ITP children who were hospitalized in West China Secondary Hospital of Sichuan University between January,2005 to January,2012 were collected.All of the patients were given hormone shock treatment and/or intravenous immunoglobulin (IVIG).According to the extent of platelet count and bleeding improvement,the outcome included complete response,response and no response.The patients were divided into the infant group(≤3 year old) and the elderly group (＞3 years old) based on age,acute group(≤6 months) and chronic group(＞6 months) based on the course of disease,their clinic data were retrospectively analyzed by software SPSS 12.0.Results (1) The male/female ratio of infants group was higher than that of the elderly group,and there was significant differences (57.1％ vs 45.3％,x2 =13.927,P ＜ 0.001).(2) The median platelet count on admission in the infant group was statistically higher than that of the elderly group(9 × 109/L vs 8 × 109/L,Z =2.448,P =0.014).The course of disease in the infant group was statistically shorter than that in the elderly group(7 d vs 75 d,Z =13.317,P ＜ 0.001).(3) The increase ratio of megakrocytes in infants group was lower than that in the elderly group,but no statistical differences were found (86.4％ vs 90.4％,x2 =2.534,P =0.111).(4) There was a significant difference in terms of hospital stays between the transfused patients and untransfused patients (6.5 d vs 7.1 d,Z =4.571,P ＜ 0.001).Under the same treatment,the time for the platelets to become normal in the transfused group was statistically lower than that in the non-transfused group (72 h vs 89 h,Z =4.116,P ＜ 0.001).(5)The time needed for the platelets to become normal (≥ 100 × 109/L) in the infant group were statistically lower than that in the elderly group(72 h vs 95 h,Z =6.540,P ＜0.001).(6)The ratio of chronic patients in the infant group was statistically lower than that in the elderly group (3.2％ vs 30.1％,x2 =178.42,P ＜ 0.001).Conclusions The male infants with ITP are more than the female and the course of disease is shorter.The infants' platelet count returns to normal faster,with better treatment efficacy and lower ratio of chronic patients.The hospital stays can be shortened in the patients with ITP who were transfused with platelets,but the course of treatment with hormone can not be shortened.

Objective To investigate the value of application of magnetic resonance imaging (MRI) in diagnosis and treatment of leptomeningeal metastases from malignant solid tumors.Methods A retrospective analysis was conducted depend on the radiological data of 63 patients who had been diagnosed as leptomeningcal metastasis of malignant solid tumors.Results All patients received brain MRI examination.26 patients underwent cervical or lumbar spine MRI examination.The MRI images showed nodular enhancement in the gyri and sulci,leptomeningeal linear enhancement,dura mater thickening and enhancement,ependymal enhancement,intraventricular metastasis,intraspinal metastatic nodules,communicating hydrocephalus,subdural hydroma and negative imaging.Ncuroimages of ependymal enhancenent,intraventricular metastasis and intraspinal implantation metastasis appeared in 5,7 and 9 patients with small cell carcinoma,respectively,which were higher than that of the other pathological types (P =0.002,P =0.009,P ＜ 0.000 1).Seizure occurred in 7 patients after intrathecal chemotherapy,of which 5 patients had pia mater linear enhancement.Among 33 patients treated with radiotherapy combined with intrathecal chemotherapy,3 patients had poor prognosis,of which 2 patients had negative imaging findings.The conditions of 25 patients were improved obviously after treatment,of which 21 patients showed different imaging remission in MRI re-examination.Conclusions The contrast MRI has an important assistant effect in diagnosis of leptomeningeal metastasis of malignant solid tumors.The MRI findings and clinical features are related with the pathological types.The pia mater linear enhancement indicates a high possibility of seizures after inthathecal chemotherapy,and it suggests that the preventive treatment should be given for such patients.MRI is not applicable to evaluate severity,prognosis and curative effect of the disease.

Objective To discuss whether it is necessary to integrate metabolic indices into diagnosis of polycystic ovary syndrome (PCOS).Methods Taking ESHRE/ASRM diagnosis as the gold standard,51 women with PCOS and 47 women without PCOS were selected and divided into the intervention group and control group respectively from the Department of Gynecology in the Second Affiliated Hospital of Kunming Medical University between January 2013 and July 2014.Logistic regression based on principal component analysis and significant variables chosen through single factor analysis were used to establish the new diagnostic model which combined reproductive indices and metabolic indices.We evaluated the validity and reliability of the new diagnostic model by using ROC curve analysis.Finally,we analyzed the consistence and difference between the new diagnostic model and the gold standard.Results Thirteen significant variables were chosen using single factor analysis.ROC analysis showed that an area under the curve was 0.976 (P＜0.001) and the optimal cut-off point was 0.526 with a sensitivity of 96.08％,a specificity of 93.62％ and a consistency of93.88％.The new diagnostic model had superior validity and reliability.The two diagnostic methods had strong consistence (Kappa=0.877,P＜0.001) and no difference (x2=0.167,P=0.688).Conclusion Considering that the integration of metabolic indices does not change the diagnosis result,we come to a conclusion that it is unnecessary to integrate metabolic indices into diagnosis of PCOS.

Objective To explore the reasonable construction of the bilingual teaching training mode for medical professional teachers so as to improve the effectiveness of the bilingual teacher training,promote the development of faculties and the quality of bilingual teaching in colleges and universities.Methods First,need analysis was done on 45 medical teachers who had taught medical scienc.e in English or intended to do it in Third Military Medical University and four basic modules were formed lectures in class,one on one instruction,self training,simulation teaching.Lectures in class are related to how to improve students' ability of language,make PPT and design teaching plans.One on one instruction focuses on pronunciation,lecture notes writing in English,trial teaching and teaching attitude;self training includes human-computer interaction in listening and speaking,independent preparation for lessons and video learning;simulation teaching is composed of trial lecture in class,teacher-student comments and demo lessons.Then 3 students participating the training was investigated and the analytic hierarchy process (AHP) was applied to calculate the weights of every indices.Results Primary index weights are:0.490 for one-on-one tutoring;0.240 for simulated teaching;0.180 for having English lessons;0.082 for independent learning.Weights of secondary indices are as the following.Trial teaching,the lecture notes writing in English and the training for English pronunciation and teachers' classroom language which are subordinate to the primary index of one-on-one tutoring are 0.180 0,0.150 0 and 0.096 0 respectively;teachers' comments and peer feed-back and demo class under the primary indices of simulated teaching are 0.120 0 and 0.091 0.Conclusion In order to improve the teaching ability in English,it is necessary to strengthen the one-onone tutoring for medical professional teachers,highlight English teachers' comments and peer assessment and excavate the effect of demo classes in the training program.

Objective To study the effect of telbivudine (TBV) on the ratio of CD4+ CD25+CD127low/-regulatory T cell (Treg) of HBeAg-positive chronic hepatitis B (CHB). Methods The ratios of Treg before and after treatment for 12, 24, 36 and 48 weeks with TBV of thirty-five patients with HBeAg-positive CHB were detected. Results Ratios of Treg were (12.55 ± 1.78)%, (10.42 ± 1.04)%, (9.55 ± 0.74)%, (8.78 ± 0.67)%, (8.74 ± 0.71)%respectively before and after treatment of 12, 24, 36 and 48 weeks and all the values were lower than its former one (P < 0.05), except the 48 weeks′. Conclusions The ratio of Treg of HBeAg (+) CHB decreases after treatment with TBV.

Objective To evaluate the application value with low-dose CT scan and quantitative analysis in airway disease of chronic obstructive pulmonary disease(COPD).Methods All subjects(34 control cases,88 cases of stable COPD patients)underwent low-dose CT chest scans,and 88 COPD patients underwent pulmonary function tests.Measuring the airway dimensions of 3th generation in apical bronchus of the right upper lobe,the posterior basal bronchus of the right lower lobe and left lower lobe.Results COPD patients with moderate to extremely severe airflow limitation demonstrated higher WA% and Pi10 in comparison with normal volunteers(all P<0.05),meanwhile patients with extremely severe airflow limitation demonstrated higher WA % and Pi10 in comparison with patients with mild airflow limitation(both P <0.05).COPD patients with severe airflow limitation demonstrated higher T/BSA and WA/BSA in comparison with normal volunteers and patients with moderate airflow limitation (all P<0.05).The WA % and Pi10 of COPD patients group were negatively correlated with ventilation indices and small airway indices(all P <0.01).Pi10 were positively correlated with lung volume indices (all P < 0.05 ).Conclusion Low-dose CT scan and quantitative analysis can provide an objective and quantitative method to evaluate the information about airway disease of COPD,inwich both WA % and Pi10 are objective indices.With the increase of air flow limitation,the bronchial wall thickness gradually increased.

Objective To discuss whether it is necessary to integrate metabolic indices into diagnosis of polycystic ovary syndrome(PCOS).Methods Taking ESHRE /ASRM diagnosis standard as gold standard,the case group composed of 51 women with PCOS and the control group composed of 47 women without PCOS were selected.By using classification tree C5.0,significant variables chosen by single factor analysis were used to establish a new diagnostic model which combined reproductive indices and metabolic indices.The validity and reliability of the new diagnostic model by using ROC curve analysis were evaluated.Finally,the consistence and difference between the new diagnostic model and the gold standard were analyzed.Results Single factor analysis chose 13 significant variables. ROC analysis showed an area under the curve of 0.930(P =0.000)and the optimal cut -off point was 0.190 with a sensitivity of 94.10%,a specificity of 91.50% and a consistency of 92.86%,which told us the new diagnostic model had superior validity and reliability.The two diagnostic methods had excellent consistence (Kappa =0.857,P =0.000)and there was no statistically significant difference (P =1.000).Conclusion Considering that whether metabolic indices are integrated into diagnosis of PCOS doesn′t change the diagnosis result,and it is unnecessary to integrate metabolic indices into diagnosis of PCOS.
