Objective To evaluate the expression of p53 in triple negative breast cancer( TNBC) and its impact on the prognosis of TNBC systematically. Methods Documents published on PubMed, Medline,CNKI,CNKI,Wanfang data,and VIP data were screened for relative researches. Two reviewers filtered,extracted and assessed the literatures according to the inclusion criteria and exclusion criteria. The meta analysis was conducted by using RevMan5. 0 software. Result A total 13 trails were included,con-taining 11 Chinese documents and 2 English documents. The meta analysis showed that p53 is significantly expressed in TNBC[OR=2. 02,95%CI(1. 28,3. 19)]. TNBC patients with positive p53 expression had higher rates in lymph node metastasis[OR=2. 02,95%CI(1. 28,3. 19)],recurrence[OR=3. 39,95%CI(1.45,7. 90)],metastasis[OR =2. 65(1. 36,5. 18)],disease-free survival[OR =0. 29(0. 18, 0. 47)]and overall survival[OR=0. 29(0. 18,0. 47)]than patients with negative p53 expression. Con-clusion p53 is overexpressed in TNBC,which plays a certain role in guiding the clinical prognosis of TN-BC. It can be regarded as an independent factor to evaluate the prognosis of TNBC,and a therapeutic tar-get in further studies.

AIM:To study the method of determing camphor, menthol, synthetic bornel and the wintergreen oil contents in Shexiang Zhunggu Plaster. METHODS: Gas phase chromatogram was used to determine contents of camphor, menthol, synthetic bornel and the wintergreen oil in Shexiang Zhuanggu Plaster. The chromatogram condition consisted of the capillary vessel column(PEG-20M, 30 m?0.32 mm?0.25 ?m). The temperature programing rose from 100 ?C to 130 ?C by 5 ?C /minute, then 30 ?C /minute to 200 ?C , lasting 2 minutes in the end. The temperature of the entrance of the capillary vessel column: at 220 ?C , temperature of the detector was 240 ?C ; N_2: 5 mL/minute, H_2: 45 mL/minute, Air: 450 mL/minute; sample quantity was 0.2 ?L. RESULTS: Under certain chromatogram condition, there was linear relation among the camphor, menthol, synthetic bornel and the wintergreen oil and the peak area in the scope of 0.027 38 mg/mL-0.438 08 mg/mL, 0.041 15 mg/mL-0.658 4 mg/mL, 0.033 38 mg/mL-0.534 1 mg/mL, 0.042 15 mg/mL-0.674 4 mg/mL, respectively. The average recoveries were 98.37%, 99.76%, 98.80% and 97.61%, respectively. RSD were 1.7%, 1.8%, 0.96% and 1.5%, respectively. CONCLUSION: This experiment provides an accurate and reliable method to control the quality of Shexiang Zhuanggu Plaster.

Staphylococcus aureus is one of the common cause of respiratory tract infections in children.Methi-cillin -resistant staphylococcusaureus was reported in 1 960s,then the resistance of other drugs were found in recent years,which leading to many problems in the clinical treatment.Clinician have to master the resistance trend and mechanism of this bacteria and decrease the speed of resistance as much as possible.

As one of the most sensitive cells of endoplasmic retieulum stress (ERS), pancreatic β-cells have an a-bundance of endoplasmic reticulum. Fatty acids cause apoptosis of β-cells and might contribute to β-cell loss in type 2 diabetes mellitus via the induction of ERS. Glucose is an amplifier of the ERS response to fatty acid, leading to increased β-cell apoptosis. ERS response mediates glucolipotoxicity-induced β-cell apoptosis.

AIM: To establish the method of fingerprinting analysis on Zedoary turmeric oil by GC.Zedoary turmeric oil for the quality control of reference. METHODS: GC method was used to determine the fingerprint and its similarity of Zedoary turmeric oil calculated on Excel and cluster analysis. RESULTS: Seventeen samples of Zedoary turmeric oil indicated that there was a little similarity among them.Based on the cluster analysis,all the Zedoary turmeric oils could be divided into two categories,self-made and market purchasing oil,the latter oils purchased from Liaoning province and Jiangsu province varied considerably.Every category had a common fingerprint mode with clear resemblance. CONCLUSION: When finding the difference between the self-made and the market purchasing Zedoary turmeric oil,quality control requires serious consideration.

Purpose: To detect the mRNA expression of epithelial skeleton protein CK19 in the peripheral blood of patients with colorectal cancer; to study its relationship to other clinicopathological parameters; and to discuss if the detection can help post-operative adjuvant therapy. Methods: A total of 39 blood samples from colorectal cancer patients were included in the study. Specific RT-PCR primers were used to avoid the amplification of pseudogenes. Results: Of 39 patients 31 showed CK19 mRNA expression (79.5%) . The patients in Dukes stage C and D showed higher frequency of CK19 mRNA expression than that in Dukes A and B (P

Objective To investigate surgical outcomes of anterolateral plus posteromedial approaches for treatment of complex tibial plateau fractures.Methods We reviewed 68 patients with tibial plateau fractures of Schatzker types Ⅴ and Ⅵ who had been treated from January 2008 to December 2011 and fully followed up in our department.They were 42 men and 26 women,22 to 64 years of age (average,42.3 years).Fractures occurred at the left side in 24 cases and at the right side in 44 cases.Intervals between injury and operation ranged from 3 to 15 days,7.4 days on average.All of them were operated on through anterolateral plus posteromedial approaches.T-or L-shaped steel plates were used laterally while reconstruction plates or T-shaped plates for distal radius were used medially.Results In this cohort the operation time averaged 3.13 hours,intraoperative blood loss 562.7 mL and hospital stay 20.4 days.All cases were followed up for an average of 18.8 months (range,12 to 38 months).Fractures healed from 4 to 8 months,6.7 months on average.The average tibial plateau angle,posterior slope angle and femorotibial angle immediately postoperation were respectively 87.3°± 1.5°,12.0°± 2.5° and 170.0°± 2.5°,not significantly different from those at one year postoperation (86.8° ± 1.2°,13.0° ± 1.8° and 171.0° ± 1.7°) (P ＞ 0.05).According to The Hospital for Special Surgery Score,the outcomes were excellent in 36 cases,good in 24 cases,fair in 6 cases and poor in 2 cases,with a good to excellent rate of 88.2％.No neural or vascular injury,deep infection,or implant failure was found in this group.Conclusion Anterolateral plus posteromedial approaches are effective for complex tibial plateau fractures,leading to anatomic reduction,stable fixation and early functional rehabilitation.
