The diversity of diagnostic criteria of idiopathic thrombocytopenic purpura (ITP) makes it difficult to compare clinical trial results and exchange clinical experiences. To address this issue, an ITP international working group convened a consensus conference in Italy in October 2007, and some new consensus concerning the terminology, definition, phases, grading of severity, prognosis, and treatment were achieved. The treatment of ITP has been dramatically improved along with the introduction of novel therapeutic agents. Rituximab, a monoclonal anti-CD20 antibody that is able to deplete autoantibody-producing B lymphocytes, has been widely applied because of its high efficacy and safety. Recent evidences suggest that decreased platelet production may also contribute to the development of ITP. Therefore, novel thrombopoiesis-stimulating agents such as thrombopoietin-receptor agonists Romiplostim and Eltrombopag have become new therapeutic options for ITP.

The incidence of cervical neoplasms complicated with pregnancy is rising,with delaying of reproouctive age.Because of the prevalence of cytology in pregnancy.eervical neoplasnis complicated with pregnancy are mostly detected early. All patients with cytological abnormalities should undergo colposcopy, and when necessary,they should undergo cervical biopsy.Conization is reserved for patients with suspected invasion.In cases of invasive carcinoma detected up to the 12th week of pregnancy,immediate treatment is prioritized.Regarding diagnoses made during the second trimester,in early-stage invasive cancers,delay of therapy seems to be safe.fetal pulmonary maturity can be awaited.And the use of neoadjuvant chemotherapy to stabilize the disease until the time of delivery appears to be viable.Doctors should draw up personalized program for the patients with cervical neoplasms complicated with pregnancy according to stage of disease, gestational weeks and the patient's desire for continued pregnancy.Cervical neoplasms complicated with pregnancy are mostly early-stageinvasive cancers, so prognosis is good.

Epithelial-mesenchymal transition (EMT) not only can endow cells migration and invasion characteristics,but also can make tumor cells obtain self-renewal ability and have the characteristics of stem cells,which might result in cancer stem cell (CSCs).There are the same molecular mechanism and microenvironment between EMT and CSCs,which have great clinic significances for the diagnosis and treatment of the aggressive cancers.Moreover,many studies show that miR-200 could regulate EMT and CSC,participate in the tumor invasion and metastasi,and promote the research of targeted cancer therapy.

Objective To investigate the clinical significance of DNA haploid analysis for malignant degree and prognosis assessment of breast carcinoma. Methods Highclarity Colourful Pathological Analysis System-1000( HPIAS-1000) was used to analyze the DNA haploid of 120 breast carcinoma patients who had been followed up for more than 5 years. All patients were divided into three groups according to histology. 48 advanced differentiation cases, 44 middle differentiation cases and 28 low differentiation cases. Then DNA haploid analysis was made,that is diploid(2C) ,3 - 4C,aneuploid(AN). Results Except for 3 -4C,there were significant differences betweenⅠandⅡgrade ,ⅡandⅢgrade,ⅠandⅢgrade( P

AlM:To explore the suitable conditions in rapid model of corneal neovascularization ( CNV ) after thermal burn under different constant temperature in rabbit.
METHODS: Total 45 New Zealand white rabbits were divided randomly into five groups ( A, B, C, D, E ) . A groups:100℃ ( n = 10 ) , B groups: 200℃ ( n = 10 ) , C groups:300℃ ( n=10 ) , D groups: 400℃ ( n=10 ) , and E groups:control group ( n=5 ) . All left eyes of rabbits in A,B,C,D groups were induced corneal neovascularization by constant temperature burning device. The growth of CNV was observed by slit lamp microscope and the area of CNV were recorded on 4 th , 7 th , 14 th , 30 th days postoperatively. SPSS 19. 0 statistical package was used for data analysis, and the data was recorded by mean ± standard deviation. Comparison by analysis of variance was made by repeated measures in the area of neovascularization at each time point in groups. Statistical tests were considered significantly when P values were less than 0. 05.
RESULTS:On postoperative 4 th , 7 th , 14 th , 30 th days: no neovascularization was found after corneal thermal burn in A group, but only a few nebula left (n=2);the area of CNV were (9.16±1.45)mm2, (37.73±5.49)mm2, (62.44± 7. 54 ) mm2 , ( 40. 28 ± 7. 39 ) mm2 in B group respectively;and (11.45±1.04)mm2, (44.51±4.64)mm2, (66.13±4.13)mm2, (43.04±2.33)mm2 in C group respectively; and (13.23± 0.86)mm2,(47.26±4.59)mm2,(67.57±4.56)mm2,(45.59± 4. 44 ) mm2 in D group respectively, and part corneal carbide ( n = 4 ) was observed as well as corneal perforation ( n= 6 ) were found on 3d in D group. No neovascularization was found in normal control group. Comparison of the areas of CNV at each time point between groups was statistically different, P < 0. 05. Statistical differences were found among B, C, D groups, P<0. 05.
COCLUSlON:ln 4 to 7d, the higher the temperature is, the more the neovascularization area of CNV are. lt has no significant difference in 14 to 30d. But corneal carbide and corneal perforation are often found in 400℃ group, so its modeling failure rate is high. lt is between 200℃ and 300℃ that repeatability and uniformity of the corneal neovascularization model of rabbit are superior.

Objective:To understand the awareness of students of medical colleges sperm behavior, attitudes and prac-tical factors. Methods:Used convenient sampling method to select 300 college students of 4 medical colleges in Shanghai conducted a questionnaire survey and used Epidata 3. 1 and SPSS 18. 0 to count and analyse. Results: 251 question-naires. 39. 8% of respondents were willing to sperm, the primary reason was considered to be an act of charity, helping others;willing sperm donors only distributed among schools statistically significant (P<0. 05) proportions, and for the various professional and grades , showed no significant difference ( P>0 . 05 ) . Conclusion:Students of Shanghai Medical Colleges sperm voluntary rate was not high, so the survey analyzed related factors affecting sperm donation and put forward practical proposals to provide reference data and methods for sperm bank sperm recruiting for volunteers in the universities.

Objective To observe the effects of IFNα-2b on keloid fibroblasts in cell prolifera-tion, apoptosis, expression of hTERT and bcl-2 mRNA and to explore its anti-keloid mechanism. Methods Primary cultures of dermal fibroblasts derived from 8 keloid and 8 normal skin samples were established, strains of fibroblasts at passages 3 to 4 were used in this study. Keloid and normal skin fibroblasts in culture medium in vitro were given IFNα-2b and were obsevered in different time. The proliferation of the fibroblasts was measured by MTT assay, the apoptosis was analysed by flow cytometry(FCM), and the expression of hTERT and bcl-2 mRNA were obsevered by semi-qnantitativere verse transcriptase-polymerase chain reaction (RT-PCR). The data were analyzed by statistical software (SPSS11. 5). Results IFNα-2b could inhibit the growth of keloid and nomal skin fibroblasts. The suppression of keloid and nomal skin fibroblasts was time-dependent. After the effect of 10 000 U/ml INFα-2b on cultured fibroblast of keloid and normal skin,the fibroblasts apoptosis was induced and the expression of hTERT and bcl-2 mRNA was lower than that of controlled group . The result was significantly different between control group and treatment group and was related with the treatment time of INFα-2b (P<0.01). Conclusions As a negative regulatory factor,interferon α-2b can suppress growth and proliferation of keloid fibroblasts and induce apoptosis. Decreasing the telomerase activity of keloid fibroblasts may be one of the most important mechamisms. That IFNa-2b inhibited telomerase activity in keloid fibroblasts is an important pathway that may play a key role in the anti- keloid therapy.

OBJECTIVETo study effects of autogenous femoral head bone grafting combined with total hip replacement for the treatment of old center dislocation of hip joint, and to evaluate the superiority of acetabular defect reconstruction with autogenous bone.

METHODSFrom March 2008 to December 2013, 16 patients (16 hips) with old center dislocation of hip joint were treated with autologous bone graft combined with total hip replacement. There were 11 males and 5 females, ranging in age from 41 to 72 years old, with an average of 56.3 years old. The duration of the disease ranged from 3.6 to 37.2 years. Twelve patients had injuries caused by traffic accidents and 4 patients were caused by falling down. The hip joint pain at the first month after operation, Harris score and hip joint movement of all patients were observed by using electronic case follow-up system.

RESULTSAll the patients were followed up, and the duration ranged from 11 to 78 months, with an average of 27.3 months. The postoperative hip joint movement of (56.2±23.4)° VAS 86.3±7.2 and Harris score 32.6±12.6 were all better than preoperative (181.8±17.6)°, 11.1±2.6 and 86.3±7.2. The joint pain was reduced and the function limitation was improved after operation, and the prosthesis position was good.

CONCLUSIONWhen the autologous femoral head bone grafting combined with total hip arthroplasty is used to treat old hip central dislocation, the initial and long-term stability of acetabular bone grafting is good, and the technique can avoid allogeneic bone complications, bone source rationally and reduce the economic burden of patients.
