OBJECTIVETo understand the clinical features of death from hand, foot and mouth disease (HFMD) and to explore the early warning index of HFMD death.
METHODSA total of 41 HFMD death cases were collected as case group in Shandong province between 2009 and 2011, and another 123 serious HFMD cases were selected as control group according to the similar gender, place of origin and hospital level, with the ratio at 1:3. We investigated the general situation, clinical treatment, past medical history, clinical symptoms and signs of the ill children, and applied the conditional logistic regression to explore early warning index of HFMD death.
RESULTSThe rate of patients who had symptoms in nervous system, digestive system, circulatory system and respiratory system were separately 90.2% (37/41), 58.5% (24/41), 53.7% (22/41) and 90.2% (37/41) in case group; and the proportions were 44.7% (55/123), 13.8% (17/123), 10.6% (13/123) and 12.2% (15/123) respectively in control group. The difference between the two groups showed statistical significance (χ(2) = 25.881, 32.791, 34.011, 86.505, P < 0.05). In case group, 37 patients had neurogenic pulmonary edema, 26 patients got encephalitis, 15 patients had respiratory and circulatory failure, 7 patients got pulmonary hemorrhage, 4 patients had multiple organ failure, 4 patients got myocarditis and 1 patient had cerebral hernia. According to multi-factor logistic regression analysis, the early warning indicators of HFMD death included neck resistance (case group: 34.1% (14/41), control group: 4.1% (5/123); OR = 7.145, 95%CI: 1.748 - 29.204), vomiting (case group: 58.5% (24/41), control group: 13.8% (17/123); OR = 5.632, 95%CI: 1.793 - 17.685) and increase of heart rate (case group: 53.7% (22/41), control group: 10.6% (14/123), OR = 6.370, 95%CI: 1.517 - 26.743).
CONCLUSIONIn the process of clinical treatment and care, we should interfere the serious HFMD patients with neck resistance, vomiting and increase of heart rate, and thereby reduce the death from HFMD.

Background:
Systemic lupus erythematosus (SLE) is an autoimmune disease under genetic control. Growing evidences support the genetic predisposition of HLA-DRB1 gene polymorphisms to SLE, yet the results are not often reproducible. The purpose of this study was to assess the association of two polymorphisms of HLA-DRB1 gene (HLA-DR3 and HLA-DR15) with the risk of SLE via a comprehensive meta-analysis.
Methods:
This study complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Case-control studies on HLA-DRB1 and SLE were searched from PubMed, Elsevier Science, Springer Link, Medline, and Cochrane Library database as of June 2018. Analysis was based on the random-effects model using STATA software version 14.0.
Results:
A total of 23 studies were retained for analysis, including 5261 cases and 9838 controls. Overall analysis revealed that HLA-DR3 and HLA-DR15 polymorphisms were associated with the significant risk of SLE (odds ratio [OR]: 1.60, 95% confidence interval (CI): 1.316-1.934, P = 0.129 and OR: 1.68, 95% CI: 1.334-2.112, P = 0.001, respectively). Subgroup analyses demonstrated that for both HLA-DR3 and HLA-DR15 polymorphisms, ethnicity was a possible source of heterogeneity. Specifically, HLA-DR3 polymorphism was not associated with SLE in White populations (OR: 1.60, 95% CI: 1.320-1.960, P = 0.522) and HLA-DR15 polymorphism in East Asian populations (OR: 1.65, 95% CI: 1.248-2.173, P = 0.001). In addition, source of control was another possible source for both HLA-DR3 and HLA-DR15 polymorphisms, with observable significance for HLA-DR3 in only population-based studies (OR: 1.65, 95% CI: 1.370-1.990, P = 0.244) and for HLA-DR15 in both population-based and hospital-based studies (OR: 1.38, 95% CI: 1.078-1.760, P = 0.123 and OR: 2.08, 95% CI: 1.738-2.490, P = 0.881, respectively).
Conclusions
HLA-DRB1 gene may be a SLE-susceptibility gene, and it shows evident ethnic heterogeneity. Further prospective validations across multiple ethnical groups are warranted.

BACKGROUNDMesh exposure after surgery continues to be a clinical challenge for urogynecological surgeons. The purpose of this study was to explore the risk factors for polypropylene (PP) mesh exposure after transvaginal mesh (TVM) surgery.
METHODSThis study included 195 patients with advanced pelvic organ prolapse (POP), who underwent TVM from January 2004 to December 2012 at the First Affiliated Hospital of Chinese PLA General Hospital. Clinical data were evaluated including patient's demography, TVM type, concomitant procedures, operation time, blood loss, postoperative morbidity, and mesh exposure. Mesh exposure was identified through postoperative vaginal examination. Statistical analysis was performed to identify risk factors for mesh exposure.
RESULTSTwo-hundred and nine transvaginal PP meshes were placed, including 194 in the anterior wall and 15 in the posterior wall. Concomitant tension-free vaginal tape was performed in 61 cases. The mean follow-up time was 35.1 ± 23.6 months. PP mesh exposure was identified in 32 cases (16.4%), with 31 in the anterior wall and 1 in the posterior wall. Significant difference was found in operating time and concomitant procedures between exposed and nonexposed groups (F = 7.443, P = 0.007; F = 4.307, P = 0.039, respectively). Binary logistic regression revealed that the number of concomitant procedures and operation time were risk factors for mesh exposure (P = 0.001, P = 0.043).
CONCLUSIONConcomitant procedures and increased operating time increase the risk for postoperative mesh exposure in patients undergoing TVM surgery for POP.

ObjectiveTo explore the correlation between the content of 4 functional components in Codonopsis pilosula roots from different areas and soil factors, and thereby to lay a theoretical basis for soil ecological regulation and improvement of quality of C. pilosula roots. MethodThe content of lobetyolin, atractylenolide Ⅲ, alcohol extract, and polysaccharides, as well as soil fertility and 16 soil factors in 24 batches of samples from different producing areas were determined. Principal component analysis (PCA) and Pearson's correlation analysis were used to explore the key soil factors leading to the variation of chemical component content in C. pilosula roots. ResultThe content of lobetyolin and atractylenolide Ⅲ in samples from Longxi was the highest, and the content of polysaccharides peaked in samples from Huguan. The content of lobetyolin was in positive correlation with soil total nitrogen, total phosphorus, total potassium, alkali-hydrolyzable nitrogen, and available potassium (P<0.01), as well as soil organic matter, pH, available manganese, and available zinc (P<0.05). There was a positive correlation between pH and atractylenolide Ⅲ content (P<0.05). Soil total potassium was in positive correlation with alcohol extract and polysaccharide content (P<0.01). Soil available zinc was positively correlated with alcohol extract and the polysaccharide content (P<0.05). Sample sites with higher PCA scores were Pingshun, Huguan, and Longxi, which were significantly positively correlated with the content of polysaccharides in C. pilosula roots in different habitats. ConclusionThe content of functional components in C. pilosula roots can be improved by raising soil organic matter content and applying specific fertilizers.

Breast cancer is a malignant tumor with high mortality, and multidrug resistance (MDR) mediated by ABCG2 (ATP-Binding cassette G2) is an important cause of chemotherapy failure. It is an urgent problem to explore the mechanism of ABCG2-mediated drug resistance and its key molecules. Epithelial cell adhesion molecule (EpCAM) is involved in multiple tumor drug resistance and is closely related to breast cancer MDR. However, its role in ABCG2-mediated breast cancer drug resistance has not been clarified. The purpose of this study was to explore the regulation of EpCAM on ABCG2-mediated MDR in breast cancer cells and its mechanism. CCK8 cytotoxicity assays confirmed that the drug resistance of MCF-7/MX cell line to mitoxantrone (MX) was significantly increased compared with MCF-7 drug-sensitive strain of human breast cancer. Western blotting results showed that ABCG2 was highly expressed and EpCAM was up-regulated in MCF-7/MX cells compared with MCF-7. SiRNA knockdown of EpCAM in MCF-7/MX cells down-regulated ABCG2 expression and restored sensitivity to MX. Cell morphology was observed under an inverted microscope, and it was found that knocking down EpCAM reduced cell-cell connections between MCF-7/MX cells. The co-localization of EpCAM and claudin 1 in MCF-7/MX cells was observed by immunofluorescence. Furthermore, Western blotting results showed that EpCAM knockdown reduced claudin 1 expression in MCF-7/MX cells. In conclusion, EpCAM may promote ABCG2-mediated mMDR in breast cancers by enhancing intercellular tight junctions through interaction with claudin 1.
