Objective To screen and identify proteins interacting with hematopoietic stem/progenitor cell differentiation-related gene HSPC016, and to explore the molecular mechanism involved in the regulation by HSPC016 on the aggregative behavior of dermal papilla cells. Methods By using yeast two-hybridization,HSPC016 gene was sub-cloned into pGBKT7 to construct the bait plasmid (named as pGBKT7-HSPC016) in yeast AH109. The cDNA yeast expression library of human dermal papillae cells in yeast Y187 was screened with the bait plasmid and the proteins interacting with HSPC016 were identified. Yeast two-hybridization retransformation experiment was conducted to exclude the false positive clones and verify the interactions, then,the positive clones were sequenced and analyzed by using bioinformatic methods. Results The bait plasmid pGBKT7-HSPC016 was constructed successfully and there was no self-activation in or toxicity against yeast AH 109. Four proteins,including forkhead family of transcription factors (FOXO 1 ), mitogen-activated protein kinase 11 (MAPK 11 ), phosphoinositide-3-kinase (PIK3R3) and liver X receptor were screened and identified. Bioinformatic analysis revealed that these proteins had close relationship with intracellular energy metabolism and translational regulation. Conclusions HSPC016 may regulate the aggregative behavior of DPCs by regulating the levels of intracellular reactive oxygen species (ROS) and interacting with signaling molecules involved in intracellular energy metabolism and translational regulation.

ObjectiveTo evaluate the risk factors of young adult stroke.MethodsTo analyze the risk factors of 203 young adult stroke. The risk factors included hypertension, lipidemia, diabetes, heart disease, TIA, family history, tobacco and/or alcohol use.ResultsHypertension was still the most frequent risk factor. Diabetes, heart disease and TIA were not much more important in young adult with stroke. Almost half of the young adult stroke had family history and hobbies of smoking and drinking.ConclusionsHypertension is an important risk factor in young adult stroke. Other risk factors such as low level of HDL, smoking, drinking and family histories still contribute to the causes of young adult stroke.

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.

Objective To investigate the biological markers and their clinical significance in diagnosis and differential diagnosis of inlfammatory bowel disease (IBD) in children.Methods The study had 22 cases of IBD including 6 cases of ulcerative colitis (UC) and 16 cases of Crohn’s Disease (CD). Twenty-four children without IBD were selected as controls. The serum perinuclear anti-neutrophil cytoplasmic antibody (pNACA) was measured by indirect immune lfuorescence method. The serum anti-saccharomyces cerevisiae antibody (ASCA) IgG and IgA, anti-B mannose glycoside antibody (AMCA) IgG, anti-B glycoside sugar shell antibody (ACCA) IgA, Anti-bacterial lfagellin antibody (Anti-cBir1) IgG, and the fecal calprotectin (FC) were determined by Enzyme linked immunosorbent assay (ELISA). Results The positive rate of serum pANCA was 100% in 6 cases of UC while it was negative in CD cases and control, and there was significant difference among three groups (P0.01). In CD cases, both positive rate of serum ACCA IgA and that of Anti-cBir1-IgG were 62.5% and the positive rate of ACCA IgA was 37.5%. Meanwhile, all of them were negative in UC cases and control. There were signiifcant differences among three groups (P<0.01). The positive rate of FC was 100% in children with IBD. It was signiifcantly higher than the positive rate in control group, 54.2% (P0.01).Conclusion The serum pANCA is a speciifc index for the diagnosis of UC. The serum ACCA IgA, AMCA IgG, ASCA IgG and IgA, and Anti-cBir1 IgG were speciifc to some extent in the diagnosis of CD. Increased FC can relfect the activity of IBD, but cannot be used for the differential diagnosis of IBD and non IBD.

Objective: This study aims to analyze the effects of catastrophic disease insurance (CDI), especially to evaluate the influences of CDI on the discrepancy of benefits between the patients covered by the Employee's Medical Insurance (EMI) and the Resident's Medical Insurance (RMI).Methods: The data used in the study are collected from the health insurance database of Zhuhai City in the years of 2012 and 2014.A descriptive analysis is made to depict the general situation of CDI in the city, and a logistic regression model is used to analyze the factors that affect the probability to get the benefits of CDI.Moreover, a triple difference model is built up to probe into the CDI's effects on the discrepancy of reimbursement ratio between patients covered by EMI and RMI.Results: The benefits of CDI favor the patients with old age, high medical expenditures and chronic diseases.When other factors are controlled, patients covered by EMI have lower probability to get CDI benefits than those covered by RMI.Within the patients with high medical expenditures who have gotten the CDI benefits, those covered by EMI enjoy higher reimbursement ratio than those covered by RMI, but CDI decreases the discrepancy by 3.2%.Conclusions: Since the CDI gives more favor to the vulnerable population and narrows the gap of the benefits between EMI and RMI, the policy improves the equity of health security.
