Objective To investigate the effects of adrenomedullin (ADM) on the expression of nuclear transcription factor-?B (NF-?B) in cultured human retinal pigment epithelial (RPE) cells. Methods Cultured human RPE cells were exposed to ADM with the concentration of 10 -7mol/L or lipopolysaccharide (LPS) with the concentration of 10 ?g/ml for 60 minutes. Nuclear translocation of NF-?B was determined by immunofluorescence staining. Western blotting analysis was used to check the expression of NF-?B protein. Results In cultured human RPE cells that were not stimulated, weak NF-?B positive green flurescence was localized in the cytoplasm. After exposed to ADM or LPS for 60 minutes, there was bright NF-?B nuclear staining in cultured human RPE cells. The results of Western blotting analysis demonstrated that in cultured human RPE cells that were not stimulated, a single weak protein strip with the relative molecular weight of 36?103 identified as immunoreative NF-?B could be observed. Both ADM and LPS could markedly increase the expression of NF-?B protein in cytoplasm. Conclusions NF-?B-dependent signal transduction pathway can be activated in cultured human RPE cells by ADM. ADM could induce NF-?B nuclear translocation and increase the expression of the protein in cytoplasm. NF-?B-dependent signal transduction pathway may play an importantrole in the function of ADM.

Objective To clone and express the new gene R049 of uropathogenic Escherichia coli 132.and to investigate the immunopmtective effects of the R049 recombinant protein on mice.Methods The pmkaryotic expression system of gene R049 was constructed by directed cloning.Thereafter,the R049 recombinant protein Was expressed and purified by Ni affinity chromatography.Polyclonal antibody was pre-pared by immunizing BALB/c mice with R049 recombinant protein.The R049 recombinant protein and whole bacterial proteins of UPEC132 were analyzed by SDS-PAGE and Western blot.BALB/c mice were im-munized with R049 recombinant protein before challenged by UPECl32 through urinary tract.Then the differences of urine and renal colony counts between immunization group and control group were compared.Results The recombinant strain E coli BL21(DE3)/pET32a-R049 ORF was constructed successfully,and the relative molecular mass of the R049 recombinant protein was 66.9×103 and its purity was up to 95% af-ter purification.The titer of polyclonal antibody wag≥1:102 400 analyzed by indirect ELISA.Both of the R049 recombinant protein and whole bacterial proteins of UPECl 32 were confirmed to show specffic reactions on the antiserunl throughh Western blot.The animal experiments showed the urine and renal colony counts of immunization group were significantly lower than that of the control group(P<0.01,P<0.05).Conclu-sion The new gene R049 of uropathogenic E.coli 132 had immunopmtective effects on mice and the defini-tive mechanism would be needed to further study.

Objective To investigate the efficiency of ring butterfly sewing in lower uterine segment aided with tourniquet in treating pernicious placenta previa combined with placenta percreta. Methods Twelve pregnant women diagnosed with pernicious placenta previa combined with placenta percreta by prenatal ultrasound in Peking University First Hospital from April 1, 2012 to November 30, 2014, were enrolled. All of them received elective cesarean delivery using ring butterfly sewing in lower uterine segment aided with tourniquet. The efficiency of this novel technique, in term of blood loss and vital signs during operation, blood transfusion, and postoperative recovery, was analyzed. Results Twelve cases were diagnosed with placenta percreta during operation, with placenta invading the perimetrium in seven cases and urinary bladder being involved in one case. Ring butterfly sewing in lower uterine segment aided with tourniquet during elective cesarean delivery was all successful in the 12 cases. The median amount of blood loss was 1 000(400-2 000) ml during operation and the amount of blood loss was lower than 1 000 ml in three cases. Two cases received no blood transfusion, and the median blood transfusion in the other 10 cases were 400(400-1 200) ml. The mean operation time was (75±22) min (43-131) min. Eleven cases had normal lochia and temperature after operation and the other one had placenta invading urinary bladder and partial placenta in situ, and developed fever at day 3 after operation, but recovered after antibiotic treatment, and no placenta tissue was seen by ultrasound at day 59 after operation. Conclusions The ring butterfly sewing in lower uterine segment aided with tourniquet is highly effective for the pernicious placenta previa combined with placenta percreta, and it is a simple, fast and fertility sparing technique with low blood loss and without usage of special equipment.

Objective To compare the severity of sensorineural hearing impairment resulted from radiotherapy (RT) and radiochemotberapy (CRT) in patients with nasopharyngeal carcinoma (NPC). Methods Between March 2002 and May 2007, 100 initially diagnosed NPC patients in Shandong Tumor Hospital and Qi Lu Hospital were randomized to RT group and CRT group. All patients underwent intensity modulated radiation therapy. In CRT group, concurrent and adjuvant CDDP were administered (CDDP 25 mg/m2/d for 3 days to 4 cycles). Pure tone auditory threshold examination was performed 1 week ,6 months, 1 year and 2 years after the completion of radiotherapy. Statistical analyses were performed using Mann-Whit-ney U test,chi-square test and Fisber's exact probability test. Results The high-frequency threshold was significantly increased in CRT group comparing with RT group at 1- and 2-year after the treatment. In RT group, the hearing threshold was impaired immediately after the treatment, partially recovered within the first year but impaired again after 2 years. In CRT group, hearing threshold was impaired at the same time and kept getting worse until 1 year after radiotherapy, which could not be recovered. Conclusions Patients with NPC treated with radiotherapy and concurrent/adjuvant chemotherapy have more severe sensorineural hearing impairment comparing with those with radiotherapy alone, especially to the high frequency sound in the speech range. Inner ear tissue tolerance should be redefined for patients receiving radiochemotherapy.
