Objective To investigate the clinical effect of mifepristone in treatment of perimenopausal dysfunctional uterine bleeding.Methods 80 cases of patients with perimenopausal dysfunctional uterine bleeding were selected and randomly divided into control group and research group,with 40 cases in each group.The control group was in the diagnosis of curettage after 10 days of oral provera 10mg every night before going to bed,stopped drug application in 14 days,15 days to retreat hemorrhages oral provera 10mg/day,stayed for 10 days,repeated drug use 5 months.The research group was treated with oral mifepristone every night before going to bed since cleaning up the uterus,12.5mg,for 6 months.Outpatient follow -up for 6 months,the recent curative effect,long -term curative effect,hormone level changes,anemia and adverse drug reactions were observed.Results The total effective rate of the research group was 95.0%,which of the control group was 82.5%,there was statistically significant difference(χ2 =7.82, P =0.005);The recurrence rate of the research group was 5.0%,which of the control group was 15.0%,there was statistically significant difference(χ2 =5.56,P =0.018).The FSH,LH,E2 and P of the two groups were decreased, but which of the research group were lower significantly than those of control group,the differences were statistically significant (all P <0.05).The decreased degree of endometrium in the research group was larger than that of the control group,the difference was statistically significant(P =0.0001).Conclusion Treatment of mifepristone perimenopausal dysfunctional uterine bleeding is significant,safe and convenient,which is worthy of clinical application.

A 59-year-old man was admitted to the Department of Ear, Nose and Throat with a complaint of six-month history of left facial numbness and toothache. There was no special previous medical history in addition to smoking. No obvious abnormality in routine electrocardiogram, chest X-ray, abdominal B ultrasound were found. (1) CT scans showed heterogeneous shadows in maxillary sinus with the lesions on the left max- illary bone and evidently destruction of alveolar bone. The histopathological examination revealed bone tissue which was partly covered by an intact adenocarcinoma cell. (2) Immunohistochemical staining foe CK7, CD117, thyroid transcription factor-1, and novel aspartic proteinase A were positive and thus compatible with metastatic lung adenocarcinoma. (3) Chest CT scans showed a 1 cm x 2 cm mass on the superior lobe of the left lung, with destruction of sternum and rib, confirming that the lesions in the paranasal sinuses were lung cancer metastases. Therefore, this patient conclusively diagnosed as lung adenocarcinoma with multiple bone metastases.

Objective To investigate the site,MR signal types and morphological characteristics of ulnar nerve in cubital tunnel for healthy adults,in order to improve the awareness of ulnar nerve.Methods Unilateral elbow of forty healthy volunteers were scanned with MR,the sequences were as follows:T1-weighted-spin-echo,T2-weighted-spin-echo-fat-suppression,PD-weighted-spin-echo-fat-suppression,among 40,13 were supine,27 were prone.The site and MR signal types and morphological characteristics of ulnar nerve were observed,the long diameter and short diameter of the ulnar nerve on different axials were respectively measured.Results On axial,ulnar nerve was posterior to the medial condyle of the humerus at proximal elbow,lied between the flexor carpi ulnaris and the flexor digitorum profunds and superficialis muscles distally.The shape of the ulnar nerve was roundness or elliptic,the signal of 40 volunteers'(100％) ulnar nerve was isointensity on T1-weighted,the signal of 17 volunteers'(42.5％)ulnar nerve was isointense on T2-weighted or PD-weighted,the MRI signal of 23 volunteers' (57.5％) ulnar nerve was slight hyperintense on T2-weighted or PD-weighted,especially on the axial of medial condyle of humerus.The variation range of long diameter and short diameter of the ulnar nerve respectively were 1.4-3.8 mm,1.0-3.0 mm.Conclusion The certain location,MR signal types and morphological characteristics of normal ulnar nerve play an important role in the diagnosis of cubital tunnel syndrome.

DNA transposon is a kind of factor that is able to translocate gene in its genome, thus offering an efficient method for permanently modifying the genome of mammals. The piggyBac (PB) transposon system has been proven effective in mammalian genomic engineering, including cancer gene discovery, animal transgenesis, in vivo gene delivery as well as in vitro genetic modification like induced pluripotent stem cells. In addition, piggyBac has many desirable features, such as seamless excision of transposons from the genomic DNA and the potential to target integration events to desired DNA sequences. Therefore, the piggyBac translocation system is an ideal genetic tool in the construction of animal models and gene therapy, and we can anticipate that the piggyBac transposon system will play a more and more important role in biomedical research.

Objective:To explore the role CD4+CD45RO+memory T cells in the pathogenesis of Hashimoto's thyroiditis (HT) by detecting the percentages of CD4+CD45RO+ memory T cells in peripheral blood mononuclear cells in peripheral blood of newly diagnosed HT patients. Methods:53HT patients and 43 matched healthy controls (HC) were included in this study. According to the thyroid functions,HT patients were divided into euthyroid subset(HT-A,n =15) ,subclinical hypothyroidism(HT-B,n=14) and overt hypothyroidism subset (HT-C,n=24). The percentages of CD4+CD45RO+memory T cells in PBMCs,as well as the level of serum IFN-γ and IL-17,and thyroid functions,and the titers of thyroid-specific autoantibodies (TPOAb,TgAb) were respectively detected by flow cytometry,ELISA,and ECLIA. Results:The percentages of CD4+CD45RO+ memory T cells in PBMCs,as well as the level of serum IFN-γ and IL-17,the titers of TPOAb,TgAb were all significantly higher than that in HC(P<0. 01). Bivariate correlation revealed that the percentages of CD4+CD45RO+ memory T cells positively correlated with the level of serum IFN-γ,TPOAb and TgAb(P<0. 01,P=0. 015,P<0. 01) in HT patients. Conclusion:The significant increase of CD4+CD45RO+memory T cells in peripheral blood of patients with HT suggested a role of CD4+CD45RO+ memory T cells in the pathogenesis of this disease.

Methods A case of apraxia with unilateral neglect after corpus callosum infarction was discussed. Results After rehabilitation, the apraxia and unilateral neglect were improved. Conclusion For similar cases, rehabilitation can significantly improve the symptoms and ac-tivities of daily living.
