Objective To investigate the expression and clinical value of miR-127-3p in plasma of patients with breast cancer .Methods 80 cases of breast patients , 70 cases of benign breast tumor patients and 70 cases of normal control group were recruited .A real-time fluorescent quantitative reverse transcription polymerase chain reaction ( RT-PCR ) method for detecting miR-127-3p was established; Liner, reproducibility, and specificity were evaluated.In addition, correlations between the relative expression of plasma miR-127-3p and the concentrations of CEA and CA 153 were assessed.the relationship of miR-127-3p expression and clinicopathological features was further determined by Mann-Whitney test.Results The method for detection of plasma miR-127-3p was established.The relative plasma expression of miR-127-3p in breast patients [ 10.561 ( 5.424 -16.465 ) ] was significantly higher than that in benign breast tumor patients [3.015 (1.987-5.035)] (P=0.000 6) and healthy controls [2.375 (1.173-4.370)] (P=0.000 2).However, there was no significant difference between benign tumor patients and healthy control group (P=0.143).Positive relationship was found between the relative expression of miR-127-3p and the concentration of CA153 (R2 =0.457, P=0.003).The area under the ROC curve (AUC) of miR-127-3pwas 0.763, which was higher than that of CEA and CA 153.No significant difference was found between plasma miR-127-3p expression and clinicalpathological features including tumor size , differentiation and tumor node metastasis stage (P>0.05).Conclusions miR-127-3p was increased in breast cancer patients and may be an important diagnostic index for breast cancer .

OBJECTIVETo explore the technique and therapeutic effect of bridge wire splint fixation with ankle dorsiflexion for the treatment of femoral shaft fractures in young children. Methods:From June 2006 to June 2012,45 young children with femoral shaft fractures were treated by bridge wire splint fixation with ankle dorsiflexion,which was designed according to arch bridge mechanical principle and structure. There were 31 males and 14 females with an average age of 3.2 years old ranging from 8 months to 5.5 years old; 14 cases were upper 1/3 femoral fractures,26 cases were middle 1/3 femoral fractures,5 cases were lower 1/3 femoral fractures; 20 cases were transverse fractures, 14 cases were oblique fractures,6 cases were spiral frac- tures, and 5 cases were comminuted fractures. X-ray, follow-up imaging changes,clinical curative effect and complications were assessed.

RESULTSForty-five patients were followed up for 6 to 21 months (averaged 12 months). All fractures were reached clinical bone healing after 5 to 7 weeks (averaged 6 weeks) fixation. Seven cases appearred limb soft tissue complications, including buttocks bedsore,dorsal foot and Achilles tendon epidermal necrosis, and healed after dressing and removal of external fixation. During follow-up,the original overlap angle and lateral displacement were remodeled, and limbs were restored to the normal line of force and bone structure. According to Flynn standard, 35 cases got excellent results, 8 cases good, 2 cases fair.

CONCLUSIONThe bridge wire splint fixation with ankle dorsiflexion for the treatment of femoral. shaft fractures in young children (less than 6 years old) is safe,feasible, simple,and has raliable effect, which can be applied in primary hospitals.

OBJECTIVETo provide anatomic evidence for identification of "holy plane" between fascia propria and its adjacent fascia in total mesorectal excision.

METHODSA total of 26 pelvic specimens of adult male preserved in 10% formalin solution were used in this study. Twenty pelvis were employed for topographic anatomy, six for sectional anatomy.

RESULTSRectovesical septum was formed by the ventral part of the fascia propria and Denonvilliers' fascia, with no blood vessel and nerve coursed between two layers. Dorsal part of the fascia propria parallelled with the presacral fascia, with no blood vessel and nerve coursed between two layers in 80% of the pelvis. However, anatomic variations was encountered occasionally--with muscle-like tissue or fusion of presacral fascia interposed between them for 20%. The lateral space of rectum was between lateral part of the fascia propria and parietal fascia which witnessed pelvic nerve plexus and lateral ligament of the rectum traveling. Pelvic nerve plexus was categorized as two types according the relation between fascia propria and nerve plexus: fusion type accounting for 85% and rarefaction type for 15%.

CONCLUSION'holy plane' is sandwiched between the fascia propria and its adjacent fascia--ventrally Denonvilliers fascia, dorsally presacral fascia and laterally parietal fascia.

OBJECTIVETo evaluate the relationship between infection burden and coronary atherosclerosis and the plaque feature.

METHODSOne hundred and eighty two patients underwent coronary angiography in Zhongshan Hospital from 2002 - 2003. Atherosclerosis and vulnerable plaque were determined by intravascular ultrasound (IVUS). Seropositivity of cytomegalovirus, helicobacter pylori, chlamydia pneumonia, hepatitis B virus, EB virus, CoxB virus, influenza A virus, influenza B virus and mycobacterium tuberculosis were determined by ELISA. The serum hs-CRP was detected by Dade Behring prospect (Immuno-nehelomitery). Patients were divided into three groups according to the pathogen burden: group A, n or= 6.

RESULTSThe pathogen burden was independent of the C-reactive protein level. Increasing pathogen burden was significantly associated with increasing atherosclerosis risk, the prevalence of atherosclerosis was 44.4%, 70.6% and 76.7% in group A, B and C. The risk associated with elevated pathogen burden was much higher when CRP was also elevated (> 5.0 mg/L) (43.8%, 70.0%, 70.8%) vs (45.5%, 63.7%, 96.8%). The positively of vulnerable plaque increased significantly when the pathogen burden was high (n > 5) (33.3%, 32.4% and 51.7% P < 0.05).

CONCLUSIONOur data suggested that infection burden was associated with prevalence of coronary atherosclerosis, and it was particularly important when C-reactive protein was elevated. The high level infection burden could predict vulnerable plaque.
