The complete mitochondrial genome sequence of Phlaeoba albonema Zheng Was determined by using L-PCR and conserved primers walking sequencing.The obtained genome sequence is 15657 bp in size.containing 13 protein-coding genes,2 ribosomal RNA and 22 transfer RNA genes.All the 37 genes are conserved in the same orientations as observed in Locusta migratoria.11202 bp of the mtDNA are coding for proteins,1486 bp for tRNAs,1312 bp for rRNA large subunit(1rRNA),and 844 bp for rRNA small subunit(srRNA).The A+T-rich region is 728 bp in size.The genes overlapping sequences are 41 bp in total and are spreading over 9 locations(1-8 bp at each site).A total of 126 bp intergenic spacer sequences are scattered in 21 regions at the size of 1 to 20 bp,where the largest 20 bp region iS located between the tRNALys and ATP8 genes.The predicted secondary structures of both srRNA and lrRNA were compared with that of Ruspolia dubia,and the patterns of base pairs in tRNA anticodon stem and A/T,C/G bias of protein-coding genes in different strands were discussed.

Objective To evaluate the value of diffusion-weighted imaging in distinguishing the benign and malignant breast lesions.Methods fifty-six female patients with pathologically proven breast lesions underwent MR diffusion-weighted imaging(MR-DWI)using 2 b values.The mean apparent diffusion coefficient(ADC)values and the relative ADC(rADC)values of lesions were measured and analyzed statistically by SPSS 13.0.Results(1)The mean ADC values of the malignant lesions and the benign lesions were(1.02?0.18)?10-3mm2/s and(1.61?0.32)?10-3mm2/s with b=500 s/mm2,(0.99?0.16)?10-3mm2/s and(1.59?0.33)?10-3mm2/s with b =1000 s/mm2,respectively.The mean ADC values of breast malignant lesions were lower significantly than that of the benign,and had statistical significance(P =0.001

Objective To discuss the clinical characteristics,treatment and prognostic factors of brain metastasis from gynecological cancers.Methods Clinical records of 25 brain metastasis patients from gynecological cancers admitted from January 1999 to January 2009 were reviewed retrospectively.The curative effects of different treatments were compared.The prognostic factors were determined using the Cox regression model.Results There were 14 cases ovarian malignant tumor,6 cases cervical carcinoma and 5 cases uterine malignant tumor.Seven cases (28%,7/25 ) had solitary metastatic lesion in the brain.Extracranial metastases were detected in 18 cases (72%,18/25 ).Five patients only received one kind of treatment,and the mean survival time was 4.0 months (0.5 to 9.5 months).Sixteen patients received combined treatment,3 of them received combined treatment including surgery,and the mean survival time was 8.4 months (4.1 to 13.4 months) ; 13 of them received chemotherapy and radiotherapy,and the mean survival time was 14.2 months (4.3 to 58.1 months).Four patients received only palliative supportive care,and the survival time was only 0.1 to 1.0 month.The Cox regression model showed that Karnofsky performance status scale,with or without extracranial metastases and the treatment method were the independent prognostic factors of brain metastasis from gynecological cancers ( P < 0.05 ).Conclusion The incidence of brain metastasis from gynecological cancers is low and the prognosis is very poor.Combined treatments may get better effects.

AIM:To explore the association between single nucleotide polymorphism in exon 33 (E33SNP) of thyroglobulin gene and Graves ’ disease ( GD) relapse after antithyroid drug ( ATD) withdrawal .METHODS:The healthy controls (232 cases) and GD patients with discontinued treatment (243 cases) were selected.According to the time of re-lapse, the GD patients were divided into A, B and C subgroups.The A group contained 77 cases of relapse within 1 year, B group contained 86 cases of relapse 1~2 years after treatment and C group contained 80 cases without recurrence within 2 years.The genotypes of E33SNP were identified by RT-PCR.The genotype ratio of thyroglobulin between control group and observation group was comparatively analyzed , and the levels of thyroid-stimulating hormone ( TSH) , free triiodothyro-nine (FT3), free thyroxine (FT4) and thyrotropin receptor antibody (TRAb), ophthalmopathy and goiter size in A , B and C subgroups in different genotype GD patients were investigated .Moreover , cumulative efficiency for patients with different genotypes in the observation group after ATD treatment within 2 years were analyzed .RESULTS:The genotype of E33SNP between observation group and control group had no significant difference , but a significant difference between A , B and C subgroups was observed (P<0.05).The levels of TSH, FT3 and FT4, and goiter size of the patients with different geno-types had no significant difference , while the TRAb levels and ophthalmopathy presented a significant difference ( P <0.05).In addition, the cumulative efficiency within 2 years for GD patients with E33SNP T/T, E33SNP T/C and E33SNP C/C genotypes was 61.8%, 42.6% and 21.3%, respectively, all with significant differences (P<0.05).CONCLU-SION:The GD patients with E33SNP C/C genotype have significantly higher TRAb level and ophthalmopathy rate than those in the patients with E33SNP C/T and E33SNP C/C genotypes, and are more likely to relapse after ATD treatment . The GD patients with E33SNP T/T genotype show a lower recurrence rate .Therefore, combination treatment or other treat-ment modalities may be more reasonable for the GD patients with E 33SNP C/C genotype.

Objective To explore the influence of continuing nursing care on sexual quality of patients after laparoscopic subtotal hysterectomy.Methods Seventy-eight patients with selective laparoscopic subtotal hysterectomy enrolled from March 2014 to April 2015 were numbered according to their enrollment date,and divided into control group and intervention group randomly.Both groups were conducted laparoscopic subtotal hysterectomy under general anesthesia.After the surgery,the control group was treated with standard nursing care and the intervention group received continuing nursing care beyond the standard nursing care.Participants' sexual quality of 3 months and 6 months after surgery were evaluated using the female sexual function index (FSFI) Results The scores of FSFI of intervention group were significantly higher than those of the control group.Conclusion The continuing nursing care of patients after laparoscopic subtotal hysterectomy can effectively improve patient's short-term sexual quality,which is worth of being applied in gynecology nursing care in the future.

The volume-time curve change in patients with normal left ventricular (LV) diastolic function and diastolic dysfunction was evaluated by real-time three-dimensional echocardiography (RT3DE). LV diastolic dysfunction was defined by E'0.05). It is concluded that PFR, as a diastolic filling index of RT3DE, can reflect the early diastolic function and serve as a new non-invasive, quick and accurate tool for clinical assessment of LV diastolic function.
