Objective To conduct the comparative study of the measurement of breast volume by MRI imaging and Archimedes method in immediate implant breast reconstruction.Methods A total of 44 patients who were diagnosed as breast cancer and undergone immediate implant breast reconstruction were selected from March 2011 to March 2013.22 cases were guided to select suitable breast implants by measuring the breast volume and correlative radial line based on MRI imaging.Control group containing 22 cases were guided to select breast implants by traditional Archimedes method and clinical experience.3 breast surgeons and plastic surgeons who did not participate in the operation were selected to judge the postoperative breast shape.Data of two groups were analyzed by using chisquare test.Results All the patients recovered smoothly after operation without infection,and the wound healed well.The breast shape was evaluated.21 cases (95.5 ％) were good in test group and 1 case (4.5％) was poor;16 cases (72.7％) were good in control group and 6 cases (27.3) were poor.The comparison between the test group and control group had statistical significance (P＜0.05).Conclusions The method to measure the breast volume and correlative radial line based on MRI imaging has important values for selecting breast implants in immediate implant breast reconstruction.It could be extensively used in clinical practice.

Bone morphogenetic proteins (BMPs) were first studied as growth factors or morphogens of the transforming growth factor-beta super family. These growth molecules, originally associated with bone and cartilage development, are now known to play important roles in morphogenesis and homeostasis in many other tissues. Recently, signiifcant contributions of BMPs, their receptors, and interacting molecules have been linked to carcinogenesis and tumor progression. BMPs can sometimes play a role as a tumor suppressor. This article explains the composition and biological characteristics of BMPs, and investigates their new roles in the pathogenesis of cancer.

Objective To investigate the relationship between body fat distribution and pulse wave velocity (PWV) in middle-aged and aged population. Methods Two hundred patients received health examination were enrolled into the male group (103 cases) and the female group (97 cases). Visceral fat volume (VFV), subcutaneous fat volume (SFV) and ba-PWV were determined. Results Compared to patients in the female group, patients in the male group had significantly higher VFV values [(3.17 ± 0.84) kg vs (2.30 ± 0.94) kg], and lower SFV values [(15.56 ± 3.49) kg vs (17.69 ± 4.82) kg], In the male group, there existed a positive correlation between ba-PWV and age, VFV, fasting blood glucose,SBP and DBP. In the female group, a positive correlation was found between ba-PWV and age, SFV, TG, BUN, SBP and DBP, while a negative correlation was observed for HDL-C and Apo A1. Conclusion There was gender differences in body fat distribution in middle-aged and aged healthy population. In the male group , age, VFV, SBP, and DBP were the only independent and significant risk factors for ba-PWV. In the female group , age, SBP and Apo A1 were the independent risk factors for ba-PWV.

OBJECTIVE:To systematically review the efficacy and safety of intrathecal injection of vancomycin combined with dexamethasone in the treatment of intracranial infection,and to provide evidence-based reference in the clinic. METHODS:Re-trieved from PubMed,Medline,CJFD,VIP,Wanfang databases,randomized controlled trials(RCTs)about intrathecal injection of vancomycin combined with dexamethasone in the treatment of intracranial infection were collected. Two reviewers independently screened literature,extracted data and assessed the risk of bias of included studies according to Cochrane system review manual 5.0.1. Then Meta-analysis was conducted by Rev Man 5.2 statistical software. RESULTS:Total of 8 RCTs were included,involv-ing 543 patients. Meta-analysis showed that,compared with intravenous dripping of ceftriaxone or vancomycin,intrathecal injec-tion of vancomycin combined with dexamethasone could significantly increase response rate [RR=1.18,95%CI(1.11,1.26),P<0.001] and bacterial clearance rate of CSF[RR=1.13,95%CI(1.01,1.27),P<0.001] of intracranial infection patients,shortened treatment time [SMD=-1.60,95%CI(-1.89,-1.30),P<0.001],reduce the incidence of ADR [RR=0.48,95%CI(0.32,0.73), P<0.001]. At the same time,it also could improve changes of intracranial pressure[SMD=-1.78,95% CI(-2.10,-1.47),P<0.001],changes of protein quantitation of CSF[SMD=-0.18,95%CI(-0.25,-0.11),P<0.001] and changes of glucose quantita-tion of CSF[SMD=1.77,95%CI(0.91,2.63),P<0.001],with statistical significance. CONCLUSIONS:Intrathecal injection of van-comycin combined with dexamethasone shows good clinical efficacy for intracranial infection,improves bacterial clearance rate, shortens treatment duration,significantly lowers intracranial pressure and protein quantitation,improves glucose quantitation of cere-brospinal fluid,with good safety.

Objective:To investigate the optimal time of coronary computed tomography angiography (CCTA) after taking nitroglycerine,and to provide basis for improving the image quantity of CCTA .Methods:43 patients underwent CCTA were scanned with coronary artery calcium score (CACS)after taking nitroglycerin 0,3,5 and 10 min.Then the diameters of the same coronary artery from the same anatomic location and the expanding rates were measured,and the change regular was analyzed with single factor analysis of variance of SPSS 17.0 software. Results:The average coronary artery expanding rate was 8% 3 min after taking nitroglycerin, and the difference was significant compared with 0 min (P<0.05);but there were 5 patients whose coronary artery didn’t expand. The coronary artery expanded obviously 5 and 10 min after taking nitroglycerin compared with 0 and 3 min (P<0.05);the maximum expanding rates at 5 and 10 min were both 38%.There were 13 and 28 patients whose coronary artery reached the maximum expanding rates (17% and 19%)5 and 10 min after taking nitroglycerin, respectively;the coronary artery of 2 patients expanded at a same level at 5 and 10 min.The average expanding rates of coronary artery had no significant differences between 5 and 10 min (P>0.05 ).Conclusion:Taking nitroglycerin can significantly expand the diameter of coronary arteries.It is necessary to perform CCTA during 5-1 0 min after taking nitroglycerine.

Objective To validate the possibility of CD133 CD34 CD44 be served as biomarkers in cancer stem cell of human lung adenocarcinoma. Methods Two kinds of culturing methods were performed to generate adhesive tumor cells and floating aggregates, and the differences of expression of CD133 CD34 CD44 between 2 kinds of cultured cells were observed by immunofluorescence. Results Floating aggregates grew more slowly, kept activity for longer period than adhesive cells (72.5% vs 47.5%,P＜0.05). Floating aggregates expressed higher level of CD133, CD34 and CD44 than adhesive cells (68.97%,82.76%,93.10% vs 5.26%,15.79%,5.26%,P＜0.01). Conclusions The combination of CD133, CD34 and CD44 probably can be used as surface markers of cancer stem cells for human lung adenocarcinoma.

OBJECTIVE: To determine the expression and clinical significance of Merlin protein in non-small cell lung cancer (NSCLC). METHODS: The expression of Merlin protein in 45 cases of NSCLC and adjacent tissue of NSCLC and normal lung tissue was checked by immunohistochemistry. The relation between the expression of Merlin protein and the multiple factors of pathological type, gender, P-TNM stage, differentiation and lymph node metastasis was analyzed. RESULTS: The expression rates of Merlin protein in NSCLC and normal lung tissue sections were 73.33% and 15.56%, respectively (P<0.05). The expression of Merlin protein was not associated with the pathological type, gender, P-TNM stage, differentiation and lymph node metastasis (P>0.05). CONCLUSION Merlin protein might contribute to the initiation of metastasis of NSCLC.
