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 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.

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

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.

ObjectiveTo investigate the relationships between traditional Chinese medicine(TCM) syndrome differentiation and serum cystatin C(Cys-C) and homocysteine(Hcy) in patients with chronic heart failure(CHF). Methods 115 cases with CHF admitted into the Department of Cardiology of the First Affiliated Hospital of Zhejiang Chinese Medical University were selected in the CHF group, and 30 cases who had taken health examination in the same period were chosen in the healthy control group. According to the TCM syndrome differentiation, the CHF cases were subdivided into four groups with different types of syndrome: 30 cases of deficiency of both Qi and Yin syndrome, 30 cases of Qi deficiency syndrome and blood stagnation syndrome, 30 cases of heart and kidney Yang deficiency syndrome and 25 casesof flooding due to Yang deficiency syndrome. The serum levels of Cys-C and Hcy in different groups were tested, and the relationships between TCM syndrome differentiation and serum Cys-C and Hcy were analyzed by using Spearman rank correlation analysis.Results The serum levels of Cys-C and Hcy in the patients with CHF were significantly higher than those in the healthy control group〔Cys-C(mg/L):1.24±0.34 vs. 0.77±0.22, Hcy(μmol/L):18.66±4.57 vs. 11.65±3.21,bothP<0.05〕. Compared with the healthy control group, the serum levels of Cys-C and Hcy in the above four groups of different syndromes had a tendency of gradual elevation in the sequence as follows: deficiency of both Qi and Yin, Qi deficiency and blood stagnation, heart and kidney Yang deficiency and flooding due to Yang deficiencygroups〔Cys-C(mg/L):1.02±0.27,1.09±0.31,1.32±0.22, 1.59±0.25; Hcy(μmol/L): 14.94±2.20, 17.66±3.04, 19.79±3.48, 22.96±5.31〕, and the elevation in levels of flooding due to Yang deficiency group was the most prominent compared with that in other groups(P<0.05). The correlation analyses showed that different types of TCM syndrome in patients with CHF were positively correlated with the levels of Cys-C and Hcy(r1=0.73,r2=0.79,bothP<0.05).ConclusionThe changes of serum Cys-C and Hcy levels are consistent with the evolution of regular pattern of TCM syndrome differentiation in patients with CHF, and these two markers can be regarded as the objective indicators of TCM syndrome differentiation of CHF.

Objective To explore the type of the rational digestive reconstruction after total gastrectomy for gastric malignancy.Metlhods Three types of digestive reconstruction were performed after total gastrectomy in 121 cases with gastric carcinoma.The operating time,morbidity and mortality,digestive tract symptoms,nutritional status in 1 year after operation were compared.Results There were no signifioant differences among the three procedures in operative morbidity and mortality,postoperative food intake,nutritional status,incidences of diarrhea and dumping syndrome.Roux-en-Y esophajejunostomy and P-type esophajejunostomy had an advantage d anti-esophageal reflux,and are obviously superior to Lahey + Braun anastomosis.Roux-en-Y esophajejunostomy was simpler with shorter operating time and less complication.Condusion Roux-en-Y esophajejunostomy and P-type esophajejunostomy could be recommended as suitable methods for digestive reconstruction after total gastrectomy.
