Objective To clone the human gene of Hepatitis B virus e antigen binding protein 1 (HBEBP1), which was screened with yeast two-hybrid system and bioinformatics techniques, to construct prokaryotic expression vector of pET-32a(+)-HBEBP1, and to induce the expression of recombinant protein in E. coli BL21. Methods The DNA fragment of HBEBP1 of about 372bp was amplified by reverse transcription PCR (RT-PCR), in which the mRNA was taken from HepG2 cells as the template, and cloned into pGEM-T vector. After restriction enzyme digestion identification and sequencing, the correct target DNA fragment was inserted into inducible prokaryotic expression vector pET-32a(+) and then transformed into competent E. coli BL21. By restriction enzyme digestion and PCR, the positive transformed clones were identified and induced with IPTG to obtain fusion protein. The HBEBP1 fusion protein was analyzed by Western blotting hybridization. Results The 372bp DNA fragment of HBEBP1 was amplified by RT-PCR. The recombinant expression vector pET-32a(+)-HBEBP1 was constructed successfully. After transformation with pET-32a(+)-HBEBP1 and induction with IPTG, the recombinant target protein of about 33kD was obtained, which was consistent with our anticipation. Western blotting assay showed that the protein had good specificity. Conclusions The recombinant prokaryotic expression vector pET-32a(+)-HBEBP1 is constructed, and the HBEBP1 gene is cloned successfully. The HBEBP1 fusion protein could be expressed in prokaryotic expression system of E. coli. These results lays a foundative for studying the immunogenicity and the biological characteristics of the HBEBP1 protein.

Objectives To investigate the association between health belief and medication adherence in hypertensive patients.Methods A total of 232 hypertensive patients who visited Outpatient Department of Huashan Hospital between October 2013 and May 2014 were recruited in this cross-section study.The degree of medication adherence was measured with Morisky scale and health belief was evaluated with questionnaires of Health Belief Model (HBM).Results Of the 232 participants,61 (26.3％),51 (22.0％) and 120 (51.7％) showed low,medium and high medication adherence in Morisky scale,respectively.Logistic analysis showed that the perceived susceptibility (P ＜ 0.001),and cues to action (P =0.004) were positively correlated,and perceived barriers (P ＜ 0.001) was negatively correlated with medication adherence of patients.Conclusion Effective interventions to improve antihypertensive medication adherence should increase perceived susceptibility,cues to action,and reduce the barriers to medication adherence of patients.

AIM:To investigate the expression and the significance of VEGF-C/D in rat cornea after alkali burning as well as the role of lymphangiogenesis in the high-risk corneal transplantation rejection.
●METHODS:The model of alkali burn corneal was made. Different times corneas were taken to electron microscope for vascularization, and examined the expression of VEGF-C/D and VEGFR-3 in l, 3, 5, 7, 14, 28d. The other rat cornea after alkali burn were divided into four parts to penetrate keratoplasty, containing only blood vessels in the cornea ( group A ) , angiogenesis and lymphangiogenesis ( group B ) , lymphangiogenesis degenerating period ( group C ) , angiogenesis degenerating period ( group D ) . ln addition, there are also normal groups ( group N ) to compare the Rl values and survival time of corneal graft.
●RESULTS: Electron microscopy showed that, when the first 7d rat cornea appeared neovascularization after alkali burn, but not lymphangiogenesis. The occurrence of new blood vessels and lymphatic in 2wk. There were no obvious lymphangiogenesis in 5wk and the angiogenesis gradually subside in 8 wk. The expression of VEGF-C/D and VEGFR-3 in the corneas of rats were up-regulated in the third days after the injury, and reached its peaks at 5d. The average survival time of group N, A, B, C, D were (14.25±0.62)d, (9.35±1.02)d, (5.06±1.13)d, (8.71±0.83) d, (9. 44±1. 05)d after transplant cornea. Compared to the rest of the group, group B plant average survival time significantly shortened (P<0. 05), while compared with group B, the survival time of A, C, D groups were significantly longer (P<0. 05).
● CONCLUSION: VEGF - C/D and VEGFR - 3 are expressed significantly after corneal alkali burn. New lymphatic vessels can accelerate high - risk corneal transplantation immune rejection.

Background and purpose:Cervical conization, including high frequency loop electrosurgical excision procedure(LEEP) has been widely used in the treatment of cervical diseases, but how to deal with the patients with pathological positive margin is a problem for clinicians.The purpose of this study was to discuss the option of adjuvant treatment after cervical conization with positive margins for patients with cervical neoplasm.Methods:The data of 528 patients who had cervical conization from 1998 to 2008 was reviewed, among which 54 patients with pathological positive margin was retreated and analyzed.Results:Fifty-four patients were divided into observation group and treatment group, 17 cases were in observation group and 37 cases in treatmeat proup.The recurrence / duration / progress rate was 17.6%(3/17), in treatment group it was 2.7%(1/37) in observation.CINⅠ-Ⅱ positive margins in both group had no recurrence;among 14 patients with CINⅢ, 1 lesion persisted, and 1 progressed to cervical squamous cell carcinoma, none in treatment group was recurrent;For those 10 patients with micro-invasive margin-positive cases, 1 progressed to squamous cell carcinoma, the remaining 9 cases were followed up for 26 months without recurrence after operation.One case in invasive cancer group had recurrence.Conclusion:The patients with CINⅢ margin-positive patients after conization should receive individualized treatment.The patient with microinvasive carcinoma should be retreated with either re-conization or hysterectomy;if with margin-positive CINⅢ after conization, or re-conization or directly treated according to guideline addressing for ⅠB, if margin showed microinvasive carcinoma.The patients with margin-positive invasive carcinoma after conization should be treated according to guideline.

Background The incidence of dry eye is growing.However,the early diagnosis of dry eye is still difficult up to now.Keratograph 5M analyzer,a novel noninvasive ocular surface analyzer for dry eye may offer important parameters.Objective This study was to evaluate the clinical value of Keratograph 5M analyzer for clinical diagnosis of dry eye.Methods An observational study was proceeded with 88 cases who accepted myopia diagnosis in Tianjin Medical University Eye Hospital from October to December 2013.A series of conventional dry eye-related examinations were performed on the patients,including tear film break-up time (TBUT),corneal fluorescein staining scoring,Schirmer Ⅰ test (S Ⅰ t),and then Keratograph 5M analyzer-related examinations were subsequently carried out,including noninvasive tear film break-up time (NITBUT) and conjunctival hyperemia scoring.The correlations between conventional dry eye-related examinations and Keratograph 5M analyzer-related examinations were assessed by using Spearman rank correlation analysis.Results A total of 88 patients were recruited with male 32 and female 56.No significant difference in age was found between different genders (P =O.34).In 88 patients,Keratograph 5M analyzer showed the non-dry eyes in 15 patients,suspicious 44 patients (50.0％) and dry eyes in 29 patients (33.0％).However,the non-dry eyes were checked out in 39 patients and dry eyes were in 49 (55.7％) based on China Dry Eye Clinical Diagnosis and Treatment Consensus.The first NITBUT (NITBUTf) was less than the average NITBUT (NITBUTav) (P =0.00),and a positive correlation was seen between them (rs =0.62,P =0.00).Dry eye grade was significantly correlated with NITBUTf or NITBUTav or conjunctival hyperemia scoring (rs =-0.60,P =0.00 ; r,=-0.89,P =0.00 ; rs =0.24,P =0.02).A negative correlation was found between the conjunctival hyperemia scoring and NITBUTav (rs =-0.24,P =0.02).However,no significant correlation was seen between conjunctival hyperemia scoring and NITBUTf,TBUT,S Ⅰ t or corneal fluorescein staining scoring (rs=-0.13,P=0.22;rs=0.16,P=0.14;rs =-0.16,P=0.13;rs=-0.08,P=0.44).No significant difference was found between TBUT and NITBUTf (P =0.71).And TBUT was correlated with NITBUTf (rs =0.23,P =0.03),but not NITBUTav (rs =0.18,P =0.09).In addition,no significant correlations were seen between S Ⅰ t and NITBUTf or NITBUTav (rs=0.20,P=0.07;rs=0.05,P=0.66).Conclusions NITBUTav has an important significance in assessing overall ocular surface conditions.The conjunctival hyperemia score is one of refrent indicators to judge ocular surface status.
