Objective To systematically evaluate the risk factors for upper extremity lymphedema after breast cancer treatment and the strength of their associations.Methods PubMed,Ovid,EMbase,and the Cochrane Library were searched to identify clinical trials published up to December 2012.The quality of included studies was assessed by the Newcastle-Ottawa Scale;data analysis was performed by Stata 10.0 and RevMan 5.2;the strength of associations between risk factors and breast cancer-related upper extremity lymphedema was described as odds ratio (OR) and 95% confidence intervals (CI).Results Twenty-two studies involving 10106 patients were included in the meta-analysis.The risk factors for upper extremity lymphedema after breast cancer treatment mainly included axillary lymph node dissection (OR =2.72,95% CI=1.06-6.99,P=0.038),hypertension (OR=1.84,95% CI=1.38-2.44,P=0.000),body mass index (OR =1.68,95% CI=1.22-2.32,P =0.001),and radiotherapy (OR =1.65,95% CI =1.20-2.25,P =0.002),while no significant associations were found for such factors as chemotherapy,age,number of positive lymph nodes,and number of dissected lymph nodes.Conclusions The incidence of upper extremity lymphedema is high among patients with breast cancer after treatment,and axillary lymph node dissection,hypertension,body mass index,and radiotherapy are the main risk factors for lymphedema after breast cancer treatment.

Objective To investigate the effects of recombinant human augmenter of liver regeneration (rhALR) on renal inflammation in acute kidney injury (AKI) induced by renal ischemia reperfusion (IR). Methods SD rats were randomly divided into sham-operated group,IR group,rhALR1 group (100 μg/kg) and rhALR2 group (200 μg/kg).Both renal pedicles of rats were identified and occluded with microvascular clamps for 60 min to induce acute kidney injury (AKI).Blood urea nitrogen and serum creatinine levels were evaluated using a Hitachi 747 automatic analyzer. For histological examination, sections were stained with HE. The activity of myeloperoxidase (MPO) was detected by spectrophotometer.Expression of TNF-α,ICAM-1,MCP-1 was determined by Western blotting. Results Blood urea nitrogen,serum creatinine levels and the injury of kidney were improved significantly in rhALR group as compared with IR group (all P< 0.05).They were improved more significantly in rhALR2 group as compared to in rhALR1 group (all P<0.05).The protein levels of TNF-α,ICAM-1,MCP-1 and the activity of MPO in kidneys from the sham-operated rats were low,and increased significantly after renal ischemia reperfusion injury (all P<0.05).After treated with rhALR,the expression of TNF-α,ICAM-1,MCP-1 and the activity of MPO were decreased significantly in kidneys as compared to those in IR group (all P<0.05),which decreased more significantly in rhALR2 group than those in rhALR1 group (all P< 0.05). Conclusions nhALR can protect kidneys from ischemia reperfusion injury in rats.The mechanism may be associated with the inhibition of renal inflammatory cells infiltration and down-regulated expressions of YNF-α,ICAM-1 and MCP-1 in the kidney.

Objective To study the expression and signiifcance of phospholipid transfer protein (PLTP) and macrophage migration inhibitory factor (MIF) in mice with bronchopulmonary dysplasia (BPD). Methods Ninety-six 4-day-old mice were randomly divided into oxygen group and air group. Mice in oxygen group were exposed to a FiO2 of 65%, and mice in air group were exposed to air. On day 7, 14, 21 and 28, blood and lung tissue samples from 12 randomly selected mice in each group were obtained. The serum levels of MIF and PLTP were measured by ELISA assay. The morphological changes of lung tissue were ob-served with HE staining. Results The mice in oxygen group showed thickened lung parenchyma and obvious pulmonary ifbrosis. The radioactive alveolar count was signiifcantly lower in oxygen group than that in air group (P<0.01). PLTP level in air group was increased gradually from day 7 to day 21, and began to decrease on day 28. PLTP level in oxygen group was increased from day 7 to day 14, and decreased on day 21 and day 28. MIF level in air group did not change during the experiment. MIF level in oxygen group was signiifcantly increased from day 7 to day 21, and began to decrease on day 28. Conclusions MIF and PLTP may be good biomarkers for the diagnosis of BPD.

Objective A retrospective analysis were conducted to identify the effect of bypassing the emergency department on 30-days outcomes of patients with acute myocardial infarction undergone primary percutaneous coronary intervention ( PPCI) . Methods From June 2014 to April 2015, 187 patients underwent PPCI in Kunming General Hospital were included. 13 patients were excluded owing to their incomplete follow-up data. The total 174 patients were divided into two groups: the control group (n =59) who did not bypass the emergency department, and the bypass group ( n = 115) who bypassed the emergency department and directly received PPCI. The data of all patients were collected and analyzed. Results There were no significant differences in baseline characteristics and PPCI related data (including percentage of thrombus aspiration catheter used, length or diameter of stents applied between two groups (all P ﹥ 0. 05) . The bypass group had shorter door-to-ballon ( D2B) than the control group [ (67. 7 ± 21. 5) min vs. (89. 4 ± 23. 6) min, P ﹤ 0. 001] . There were no significant differences in 30-days all-cause mortality, re-myocardial infacrtion and target ressel revascularization (TVR) between the two groups (P ﹥ 0. 05) . Total MACEs rate in the bypass group was lower than in the control group (10. 2% vs. 1. 7% , P = 0. 012) . Logistic regression analysis showed that age, diabetes, pain-to-door (PTD) time and CK peak value were the main influencing factors for 30-day MACEs rate of patients receiving PPCI ( P ﹤0. 05) . Conclusions Bypassing the emergency department can shorten D2B time and reduce 30-days MACEs post-PPCI, but reducing the total ischemic time will be more beneficial to patients with acute myocardial infarction.
