On the basis of assuming that the postgraduate education charge is a fact,this paper at fist studies the theory and realistic basis of postgraduate student charges and then analyzes its profit and fraud. Finally,some constructive suggestions are put forward to protect the enrollment chances of poor students and the development of basic discipline.

Objective:To explore the multiple meditation effects of emotional intelligence and self-esteem between interpersonal initiative personality and social positive adaption in left-behind junior high school students.Methods:Totally 331 left-behind junior high school students [165 boys,160 girls,average age of (14.5 ± 1.2) years] were selected.They were assessed with the Interpersonal Self-Support Scale for Middle School Students (ISSS-MSS),Emotional Intelligence Questionnaire (EIQ),Rosenberg Self-Esteem Scale (RSES) and Social Adjustment Scale (SAS-YB).Results:The scores of social positive adaption were positively correlated with the scores of interpersonal initiative personality,EIQ and RSES (r ＝ 0.47-0.67,Ps ＜ 0.001).Path analysis showed that interpersonal initiative personality had direct effects on social positive adaption (β ＝ 0.47,P ＜0.001).Mediation modeling showed that interpersonal initiative personality could exert effects on social positive adaption indirectly through the mediating effect of not only emotional intelligence,but also self-esteem (x2/df＝ 3.03,TLI ＝ 0.87,CFI ＝ 0.89,RMSEA ＝ 0.08).Conclusion:The present study indicates that parallel multiple mediation model of emotional intelligence and self-esteem could explain the mechanism of influence of interpersonal initiative personality on social positive adaption appropriately.

Objective: To get the information about freshmen's mental health and it relationship with sex, city and countryside difference, and to provide the reference for effective mental health education and consultation. Methods: The situation of 1351 freshmen's mental health was surveyed by using UPI. Results: ①11.91% of the freshmen had serious mental derangement, 26.15% of them had a little psychological problem. ②The distinct difference existed not only between male and female, but also between city and countryside. The mental health of male students surpassed the female students, the city students surpassed the countryside students. Conclusion: The situation of medical freshmen's mental health should not be neglected, and its influence factors are various. Mental health education and consultation should be pointed to the students.

A database model of ontology was established by mining the EMR-covered data according to the con-cept of fuzzy vector space model with Kawasaki disease as an example. The evidence and model for the diagnosis and treatment of Kawasaki disease were detected fromthe EMR of Kawasaki disease in the database model of ontolo-gy in order to help the clinicians to make its differential diagnosis and improve its treatment plan, thus achieving the effective EMR data mining and promoting the computer-aided clinical decision-making.

Objective To investigate the protective effects of Cilazapri l on focal cerebral ischemia of spontaneous hypertensive rats. Method Focal cerebral ischemia of spontaneous hypertensive rats wer e made by occlusion of the middle cerebral artery(MCA). Cilazapril treated group was taken cilazapril 4 weeks before model was made. TTC staining,HE staining,Nis sl's staining,immunohistochemistry, and image analysis were taken to estimate th e area of ischemia,number of dead neural cells,optical density of positive cell of Nissl's staining,HSP70 and NF-k BP65 immunohistochemistry reaction in ischem ia area. Result Cilazapril could reduce the area of ischemia and behavior sc ores,decrease the number of died neural ce lls,increase the optical density of positive cell of Nissl's staining,reduce th e optical density of NF-k BP65. No effect on HSP70 immunohistochemistry reactio n was found. Conclusion Cilazapril could decrease infarction of focal ischemia o f spontaneous hypertensive rats, promote the functional restoration of rats,decr ease nerve cell death,inhibit the expression of NF-k B. Cilazapril inhibited in flammatory reaction and that could be one of its protective mechanisms.

Objective:To investigate the diagnosis and treatment for incarceration of retroverted uterus in pregnant women.Methods:This study retrospectively recruited four gravidas with incarcerated retroverted uterus indicated by prenatal ultrasonography in Hunan Provincial Maternal and Child Health Care Hospital from August 2016 to February 2020. Clinical features, diagnosis, and treatment of these cases were described.Results:Vaginal bleeding or discharge were the main symptoms of the four cases and prenatal ultrasound suggested incarcerated retroverted uterus. Obstetric examination was performed for all cases, except one due to small gestational age, and bulging posterior fornix was found in one case. Three cases were diagnosed in the third trimester and one at 14 gestational weeks. In light of gestations, symptoms, and anterior uterine muscle thickness, three patients underwent planned cesarean sections with a median abdominal incision and a superior transverse uterine incision after fetal lung maturation acceleration. Uterus involution was good, and the incisions healed well in these three cases, with all neonates in good condition. Following a two-week knee-chest position treatment, the position of her uterus and bladder turned normal in case 4.Conclusions:Considering the atypical clinical presentations, clinicians should be aware of incarceration of retroverted uterus when related symptoms or signs were presented. Placenta previa might be the comorbidity and should be differentially diagnosed. The timing of a cesarean section is supposed to be determined based on multiple factors. Moreover, a median abdominal incision and a superior transverse uterine incision are recommended, and an anatomic landmark is often required for the latter's accurate position.

Objective To investigate HIV high risk population size estimation method,analyze the epidemic situation in China and offer scientific evidence for policy making. Methods Appropriate methods to estimate different type high risk populations were ascertained by experimental study. Results Size estimation methods and procedures for different type high risk population were formed.Epidemic estimation and parameters fit for China were ascertained.HIV epidemic situation and characteristics were stated. Conclusion Methods formed in the study are the key points for the understanding of number of PLWHA,for the exact judgment of HIV epidemic,for the improvement of inspection system and examination work,for the formation of "Four Free and One Care".

Objective:To investigate the correlation between the expression of vascular endothelial growth factor receptor KDR ,somatostatin (SS) and angiogenesis in pancreatic carcinoma and their association with the clinicopathologic characterizations. Methods:Immunohistochemical SP technique was used to detect the expression of KDR and SS. Microvessel density was determined by immunostaining for factor CD34 related antigen. Results:MVD was higher in KDR high and middle expression cases than that in low expression cases(P
