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.

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.

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.

Vascular endothelial growth factor (VEGF),platelet derived growth factor (PDGF) and complements play key roles in the pathogenesis of age-related macular degeneration (AMD).Pegaptanib,the first therapeutic aptamer against VEGF165,has been approved by the Food and Drug Administration (FDA) of US for the treatment of exudative AMD.Another two aptamers El0030 and ARC1905,each target PDGF-B and complement C5 respectively,are undergoing clinical trials.Recent trends to treat AMD are combined therapies targeting multiple key molecules in the pathogenesis of AMD;aptamers against multiple targets may become the preferred drug for AMD.

Objective To study in patients with stable chronic obstructive pulmonary disease treatment, the use of Tiotropium Bromide Powder for Inhalation treatment combined with psychological intervention effect.Methods In 40 cases of patients with stable chronic obstructive pulmonary disease treatment using tiotropium bromide powder for inhalation, and classified as the control group, the other 40 patients in the control group based on the use of psychological intervention combined with treatment the treatment, and classified as the observation group, two groups of patients were in our hospital from January 2016 to January 2017.Results There was no significant difference in anxiety and depression of patients in the two groups before intervention, after the intervention group patients in the observation group improved significantly better;two groups of patients before intervention PaCO2, there was no significant difference in PaO2 index, after group intervention of patients in the observation group improved significantly better;compared two groups of patients with the treatment efficiency, the obvious observation group were higher, there were significant differences (P<0.05).Conclusion Tiotropium Bromide Powder for Inhalation combined psychological intervention treatment of patients with stable chronic pulmonary disease blocking was observed, which can improve the patient's condition, and improve the treatment effect, the patient's mental state adjustment also has a positive effect, it is worthy of reference.
