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.

Objectives To report the clinical features and treatment in a case with paroxysmal diagonistic ideomotor apraxia after ischemic infarction of the corpus callosum.Methods The neuropsychological tests,brain MRI,the TCD and carotid duplex sonography were carried out in the patient who is right handed and had had presentation of paroxysmal diagonistic ideomotor apraxia for ten days.Results Neuropsychological tests confirmed the diagnosis of paroxysmal diagonistic apraxia in this patient.MRI showed ischemic infarction in the right corpus callosum.The symptomsin the patient were improved after the treatment with aspirin for three months.Conclusion The infarction of corpus callosum may induce paroxysmal diagonistic apraxia.

Objective:The clinicopathological features, diagnosis, and prognosis of follicular thyroid carcinoma (FTC) with distant me-tastasis as the first manifestation were evaluated in this study. Methods:A total of 129 FTC cases with clinical data were retrospective-ly analyzed in the Department of Pathology, Tianjin Medical University Cancer Institute and Hospital (January 2001 to January 2016). Survival analysis and conjoint analysis on FTC with clinical data, diagnosis, and morphological characteristics with distant metastasis as the first manifestation were performed. Results:Among the 129 FTC cases, 24 cases demonstrated distant metastasis as the first mani-festation (18.6%). Bone metastasis was the most common (13.2%). The presence of mass and pain at the metastatic sites were the usu-al clinical complaints. The morphological characteristics of FTC with distant metastasis can be classified into four subtypes:microfollicu-lar (10 cases), solid (4 cases), normofollicular (9 cases), and macrofollicular (1 case). Immunostaining tests on thyroglobulin and thyroid transcription factor-1 showed positive results in FTC with metastasis. Survival analysis showed that the five-year survival rates in the 24 cases were 87.1%. The prognosis of patients with solitary metastasis was better than that of patients with multiple metastasis (P=0.022). A higher survival rate was found in the normofollicular and macrofollicular subtypes than that detected in the microfollicular and solid subtypes (P=0.012). Conclusion:FTC is susceptible to distant metastasis. Some patients with FTC demonstrated distant me-tastasis as the first manifestation, and their diagnosis can be confirmed by pathological feature analysis and immunostaining. The prog-nostic significance is possibly related to the number of lesions of FTC with distant metastasis and histopathological subtypes.

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 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 investigate the effect of vardenafil on high altitude pulmonary hypertension in rats, and the possible mechanism thereof. Methods Thirty rats were randomly divided into three groups:control group with normal-pres?sure and normal-oxygen (group C), pulmonary hypertension group with low-pressure and low-oxygen (group P), and the group treated by vardenafil in low-pressure and low-oxygen condition (group V). The rats of group P and group V were ex?posed to low-pressure and low-oxygen condition in an auto-modulating hypobaric and hypoxic cabin to simulate 5 000 m high altitude environment (air pressure 50 kPa, oxygen concentration 10%) for 8 hours daily. Vardenafil (1 mg/kg) was given by gastrogavage to rats in group V once daily for 4 weeks, while the isodose distilled water was given by gastrogavage to rats in group C and group P. The mean pulmonary arterial pressure and right ventricular mass index were measured respectively after 4-week treatment. Morphologic changes of peripheral pulmonary artery were detected by light microscope. The serum levels of nitric oxide (NO) and endothelin-1 (ET-1) were detected as well. Results The pulmonary arterial pressure and right ventricular mass index were significantly higher in group P than those of group C and group V (P<0.05). The ratio of vascular medial wall thickness to external diameter (WT%) and the ratio of pulmonary artery wall area to tube area (WA%) were significantly increased in group P than those of group C and group V (P<0.05). Furthermore, the serum level of NO was significantly lower in group P than that of group C and group V, but the serum level of ET-1 was significantly increased compared with that of group C and group V (P<0.05). Conclusion Vardenafil can effectively reduce the pulmonary arteri?al pressure, and attenuate pulmonary vessels and right ventricle remodeling induced by high altitude pulmonary hypertension.

Objective Peritoneal dialysis can be done at home , however , its clinical follow-up quality is lower compared with hemodialysis due to the lack of detailed follow-up system and professional management team for post-discharge nursing care .The article aimed to explore the effect of a nurse-led integrated specialized disease management model in the follow-up of peritoneal dialysis patients . Methods Nurse-led integrated specialized disease management model was provided for 270 patients with peritoneal dialysis (PD) from January 2012 to May 2013.Self-designed questionnaire on diasease knowledge and self-care assement questionnaire were used for patients to evaluate their self-care ability and understanding of disease knowledge .Regular follow-up continued . Results The patients′understanding of disease knowledge was on the rise at 1st day before discharge, 1st month and 3rd months after discharge. After the application of nurse-led integrated specialized disease management model , the patients′regular clinical follow-up rate was in-creased from 78.3% to 88.6%.The patients′self-care ability improved gradually at 1st day before discharge , 1st month and 3rd months after discharge , which was of significant differences . Conclusion The nurse-led nurse-led integrated specialized disease management model can improve peritoneal dialysis patients′self-care ability and reduce their medical expense , which is of clinical sig-nificance .

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.

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.
