Astract:Objective To assess the anatomical and functional significance of the bladder and urethra in female SUI by dynamic MRI and urodynamic. Methods The clinical data were retrospectively analysed on 60 cases of female stress urinary incontinence from Feb 2011 to Nov 2013. All the women received pelvic floor dynamic MRI and Urodynamic study. Measured the urethral angle,the distance of the H line, M line and the descent of the bladder,cervical,anorectal junction from the PCL in the mid-sagittal dynamic MR image of the pelvic. Pearson 's correlation coefficient was used to examine the association among the distance of the H line,M line and the urethral angle,the descent of the bladder,cervical,anorectal junction from the PCL and the Urodynamic data. Results The distance of the H line,M line were significantly and positively associated with urethral angle and the descent of the bladder,cervical,anorectal junction from the PCL. The distance of the H line,M line were significantly and negatively associated with functional profile length, maximum urethral closure pressure,VLPP and detrusor opening pressure. Conclusion Pelvic floor dynamic MRI combined with Urodynamic study is useful for assessing the anatomical and func-tional significance of the bladder and urethra in female SUI.

Methylotrophy is a kind of widespread microbe which can use carbon compound as their only carbon and energy sources.It has been reported that methylotrophy can directly use one carbon com-pound to transform into their own metabolic one carbon unit,then these one metabolic one carbon units can be used as energy and carbon skeleton by organisms,which is a main part in one carbon metabolism.Because this is a novel metabolic system,it can be used in the study of biological metabolism and evo-lution.Based on the previous study about Methylobacterium sp.MB200 in our lab,here we summarized the research improvements about methylotrophy from their taxonomy,metabolism,genomics and ap-plications.

Objective To investigate the effects of microRNA (miR)106a on the proliferation, apoptosis, migration and invasion of thyroid cancer cells in vitro.Methods 8505C and CGTH-W3 cell lines were used in the study.Overexpression and inhibition of miR106a were achieved by transfection of lentiviral vectors.The changes of gene expression were detected by quantitative real-time PCR (qRT-PCR) and Western blot analysis.Cell viability and apoptosis were evaluated by MTT assay and flow cytometry analysis, respectively.The caspase-9 activities in parental CGTH-W3 and 8505C cells and transfected sublines were measured.Wound healing and Transwell invasion assays were performed to determine cell migration and invasion.Two-sample t test and one-way analysis of variance were used to analyze the data.Results The level of miR106a in 8505C was up-regulated when compared to that in CGTH-W3 cells (t=10.28, P<0.01).Scrambled control and miR106a(-) were also successfully transfected into cells.Inhibition of miR106a suppressed cell viability, migration and invasion while promoted apoptosis and caspase-9 activity of 8505C cells, with significant differences among 8505C, 8505C-control, 8505C-miR106a(-) cells (F=147.0, 19.2, 100.3, 537.8, 804.3;all P<0.01).Overexpression of miR106a promoted cell viability, migration and invasion while inhibited apoptosis and caspase-9 activity of CGTH-W3 cells, with significant differences among CGTH-W3, CGTH-W3-control, CGTH-W3-miR106a(+) cells(F=9.2, 13.3, 622.8, 12.3, 19.6, all P<0.01).In addition, miR106a may up-regulate the expression of MEKK2 and p-ERK1/2.Conclusion Acting as an onco-miR, miR106a might promote the proliferation, migration and invasion of thyroid cancer cells and inhibit their apoptosis in vitro.

DTC is the most common endocrine carcinoma and its routine treatment consists of total thyroidectomy and 131I thyroid remnant ablation.Currently,standard follow-up for DTC comprises Tg measurement and neck ultrasound as well as an additional radioiodine scan when indicated.As thyroid cells are assumed to be the only source of Tg in serum,circulating Tg serves as an excellent marker of persistent or recurrent disease in DTC follow-up.With the development of highly sensitive Tg assays,now it is possible to detect very low Tg concentrations which reflect minimal amounts of thyroid tissue without the need for TSH stimulation.This review is to introduce clinical implications of highly sensitive Tg assays.

ObjectiveTo investigate the value of serum creatinine(SCr) to monitor the renal function of patients with spinal cord injury(SCI).Methods1298 SCI patients were investigated in Beijing Charity Hospital from January 2004 to May 2009. 249 healthy people were involved as control. The data of SCr were analysed.ResultsThe level of SCr for the SCI patients was (56.81±14.33) μmol/L with normal distribution, 95% CI was 28.73～84.89 μmol/L; The level of SCr for the healthy people was (75.98±11.34) μmol/L, 95% CI was 57.36～101.80 μmol/L. The level of SCr was significantly lower in the SCI patients comparing to the healthy people (P<0.01). Among the SCI patients, the level of SCr was (59.59±13.76) μmol/L for male while (46.41±11.31) μmol/L for female(P<0.05). There was no difference in level of SCr among different ages of the SCI patients(P>0.05). The characteristics were likely in the two groups. There was no difference in level of SCr between paraplegic (55.54±14.96) μmol/L and quadriplegic (57.67±13.83) μmol/L (P>0.05).ConclusionThe characteristics of level of SCr were likely in SCI patients and healthy people with normal distribution. The level of SCr was lower in SCI patients comparing to healthy people, which was higher for male SCI patients comparing to female SCI patients.

Objective To investigate the serum lipids levels of Chinese men with chronic paraplegia.Methods A total of 650 male paraplegics admitted to the China Rehabilitation Research Center (CRRC) for rehabilitation therapy from Jan 2004-Dec 2008 were investigated. The inclusion criteria were a definite paraplegic history (T2-L5 spinal cord injury); complete data; age 18-60 years; and no history of stroke. TG, TC, LDL and HDL serum lipid profiles were studied. Results These male paraplegics showed significantly higher mean TG and TC levels and lower mean HDL levels than the nation-wide averages for similar males ( TG 1.72 mmol/L vs. 1.36 mmol/L; TC4.42 mmol/L vs. 4.30 mmoL/L; HDL 0.99 mmol/L vs. 1.18 mmol/L). No difference in average LDL levels was found. TG, TC and LDL levels were correlated positively with age, but HDL was not. Duration of paraplegia correlated positively with HDL levels, but negatively with LDL. The prevalence of dyslipidemia was 67% , and the prevalence of low HDL was 64%. Conclusions The serum lipid profiles of the young male paraplegics showed a high prevalence of dislipidemia, significantly low HDL levels with a high prevalence of low HDL, and no correlation with age. TG, TC and LDL levels increased with age. The duration of paraplegia was correlated positively with HDL but negatively with LDL, probably due to increased exercise of the upper limbs.
