Objective To study the expression of small breast epithelial mucin(SBEM) in the peripheral blood of the patients with breast cancer,and explore the correlation between micrometastasis and SBEM.Methods Peripheral blood samples were obtained from 92 patients with breast carcinoma,20 patients with benign breast diseases,10 patients with malignant tumor not originating from breast,and 10 normal healthy volunteers.SBEM-mRNA expression was detected by nested reverse transcription-polymerase chain reaction(Nested-RT PCR).Results Among 92 breast carcinoma patients,43(46.7%) were Nested-RT-PCR positive for SBEM-mRNA,but it was negative in all the other groups.The expression of SBEM-mRNA in peripheral blood did not correlate with ER or PR status,menstruation state or primary tumour size.but correlated with patient′s age,the state of Her-2,CEA,CA15-3 and axillary lymph node metastasis of breast cancer.Conclusions The expression of SBEM-mRNA in peripheral blood of breast cancer can be of potential use to monitor the micrometastasis of breast cancer.

BACKGROUND:Many patients underwent aspirin anticoagulation in preventing cardiovascular disease before hip and knee replacement. No report addressed the effect of aspirin on blood loss during perioperative stage in patients receiving hip and knee replacement. OBJECTIVE:To observe the effect of perioperative continuous low-dose aspirin anticoagulation application on total hip arthroplasty or total knee arthroplasty. METHODS: A total of 40 patients with primary total hip arthroplasty or total knee arthroplasty were enroled in the Department of Orthopedics, Tianjin First Center Hospital from December 2012 to August 2013. According to anticoagulation scheme, they were divided into two groups (n=20). In the observation group, 100 mg/d aspirin anticoagulation was continuously used before replacement for a long period, and the medicine was not withdrawn except the day of replacement. In the control group, aspirin anticoagulation was not used, and their ages were similar to the observation group. The operation was conducted by the same physician in the observation and control groups. 10 patients received total hip arthroplasty and 10 patients received total knee arthroplasty in both groups. Bleeding was stopped actively during replacement. After replacement, pressurized ice compress was used to reduce bleeding. At 48 hours after replacement, wound drainage, perioperative hemoglobin and the incidence of complications were recorded. Joint function recovery was observed at 3 months of folow-up. RESULTS AND CONCLUSION:Hemoglobin levels before and after operation, postoperative blood drainage at 48 hours, perioperative hemoglobin changes, the incidence of complication, and joint function score at 3-month folow-up did not show significant difference between both groups. These findings indicate that it is safe to use some measures for reducing blood loss and continue low-dose aspirin in the perioperative period. The use of aspirin did not impact blood loss.

Recent studies show that the abnormalities of dickkopf-1 (DKK-1)are closely related to the bone metastasis and therapeutic effect of breast cancer,prostatic carcinoma,multiple myeloma,neuroblastoma and non-small cell lung cancer.Clinical researches of large sample on the relationships between serum DKK-1 concentration and malignant tumors bone metastases have important clinical significance for evaluating the value of DKK-1 as a clinical biological biomarker of bone metastases and understanding the tumor mechanisms of bone metastases.

Objective To discuss the effect of Yifei Mixture (YFM) on quality of life in patients with chronic obstructive pulmonary disease (COPD) at stable phase. Methods Sixty patients with COPD were randomly divided into the control group with small dose Aminophylline Sustained-release Tablets and inhaling Salbutamol or becotide (30 cases), and the observation group with YFM 100 mL, po, Bid (30 cases). Results There was significant statistical differences between the two groups, which shows that the observation group was superior to the control group in amelioration of syndrome, pulmonary function, the times of hospitalization yearlong days, single hospitalization and the integration of SGRQ. Conclusion YFM can slow down the progression of COPD, reduce the time of hospitalization and improve quality of life.

Objective To explore the curative effect of triple lumen feeding tube on upper gastroin-testinal tract perforation after endoscopic operation.Methods A total of 1 12 patients with upper gastrointes-tinal perforation after endoscopic operation were involved in this prospective control test.The remission rate of abdominal pain and abdominal distension,gastric pH,lesion healing time,length of stay and the success rate of conservative treatment were compared between the control group (indwelling traditional gastric tube and intravenous use of omeprazole injection)and the experimental group (intestinal administration of PPI through triple lumen feeding tube).Results The remission rate of abdominal pain of the experimental group was 61. 3% at 6 hours,and 83. 2% at 12 h,which were significantly higher than those of the control group (P<0. 05 ).The lesion healing time(of cases where lesions were not clipped)and length of hospitalization of the experimental group were significantly shorter than those of the control group(P<0. 05 ).The gastric pH and success rate of conservative treatment of the two groups had no significant difference(P>0. 05 ).Con-clusion The curative effect of triple lumen feeding tube on upper gastrointestinal tract perforation after endo-scopic operation is ideal.

Objective To discuss the clinical value of transesophageal echocardiography used in extracorporeal circulationcardiac valve replacement. Methods 89 patients received extracorporeal circulation cardiac valve replacement in our hospital from January 2012 to December 2014 were included in the study. Transesophageal echocardiography were performed preoperatively, intraoperation and postoperatively and the findings were compared to the result of preoperation transthoracic echocardiography exam. The measurement of aortic annulus diameter and detection rates of calcification obtained by transthoracic and transesophaged echocardiography were compared. Changes in heart function parameters before and after operation were compared. The alternations in surgery plan made after pre-operative transesophageal echocardiography exam and any relevant treatment or procedure performed according to intra-operation transesophageal echo findings were recorded. All the patients were followed up for 6 months - 40 months. Results Before extracorporeal circulation cardiac valve replacement, the aortic annulus diameter measured and detection rates of calcification by transthoracic echocardiography were smaller and lower than actual surgical pathology results ( P < 0. 05 ) . No differences in the results from transesophageal echocardiography of two-dimensional and three-dimensional examination when compared to pathological findings ( P > 0. 05 ) . Conclusions For patients receiving extracorporeal circulation cardiac valve replacement, transesophagus echocardiography examination is helpful to guide the selection of valve stent and operation methods.

Production of bioethanol using starch as raw material has become a very prominent technology. However, phytate in the raw material not only decreases ethanol production efficiency, but also increases phosphorus discharge. In this study, to decrease phytate content in an ethanol fermentationprocess, Saccharomyces cerevisiae was engineered forheterologous expression of phytase on the cell surface. The phy gene encoding phytase gene was fused with the C-terminal-half region of α-agglutinin and then inserted downstream of the secretion signal gene, to produce a yeast surface-display expression vector pMGK-AG-phy, which was then transformed into S. cerevisiae. The recombinant yeast strain, PHY, successfully displayed phytase on the surface of cells producing 6.4 U/g wet cells and its properties were further characterized. The growthrate and ethanol production of the PHY strain were faster than the parent S. cerevisiae strain in the fermentation medium by simultaneous saccharification and fermentation. Moreover, the phytate concentration decreased by 91% in dry vinasse compared to the control. In summary, we constructed recombinant S. cerevisiae strain displaying phytase on the cell surface, which could effectively reduce the content of phytate, improve the utilization value of vinasse and reduce the discharge of phosphorus. The strain reported here represents a useful novel engineering platform for developing an environment-friendly system for bioethanol production from a corn substrate.
