Background and purpose:Promoter methylation ofPCDH10, a gene encoding protocadherin 10, has been found to be correlated to poor prognosis in gastric cancer (GC) patients. However, the relationship between the expression of PCDH10 and prognosis in GC remained unknown. This study aimed to explore the relationship be-tween the expression of PCDH10 and clinicopathological features and prognosis of GC, and to identify biomarker for predictions of recurrence and survival of GC.Methods:mRNA expressions of PCDH10 in 115 pairs of GC tissues and adjacent normal tissues were detected by real-time lfuorescence quantitative polymerase chain reaction (RTFQ-PCR). The correlation between PCDH10 expression level and clinicopathological features and prognosis of GC was analyzed. Prediction models for 5-year recurrence and 5-year survival were established using logistic regression method.Results:Progression-free survival (PFS) and overall survival (OS) were signiifcantly prolonged in patients with PCDH10 low expression compared to patients without PCDH10 low expression (P=0.046 andP=0.033 respectively). PCDH10 low expression signiifcantly correlated with less lymph node metastasis (P=0.001) and earlier TNM staging (P=0.001), and was more common in female than in male (P=0.040). The mRNA expression of PCDH10 did not correlate with age, Lauren classiifcation, T stage, neural invasion or vascular invasion. Univariate Cox analysis showed Lauren classiifca-tion, T stage, N stage, M stage and PCDH10 expression signiifcantly correlated with PFS and OS. Logistic regression models for the prediction of 5-year recurrence or 5-year survival based on clinicopathological features included Lauren classiifcation, T stage, N stage and M stage as variables. Logistic regression models for the prediction of 5-year recur-rence or 5-year survival based on PCDH10 expression included Lauren classiifcation, T stage, M stage and PCDH10 expression level but not N stage as variables. The models based on PCDH10 expression had the same effciencies as models based on clinical parameters in predicting 5-year recurrence or 5-year survival for GC patients.Conclusion:PCDH10 low expression correlated with better prognosis, less lymph node metastasis and earlier TNM stage in GC patients. Low expression of PCDH10 may be a biomarker of better survival for GC patients. Logistic regression model based on PCDH10 mRNA expression may serve as a prediction model when patients have unknown lymph node metas-tasis status.

Objective:To observe factors influencing the risk of urinary tract infection (UTI) after cerebral hemorrhage (ICH).Methods:A total of 77 ICH patients undergoing rehabilitation between August 2015 and August 2017 were studied. Among them, 24 were diagnosed with a UTI according to clinical manifestations and urine routine tests and urine culture. They formed the UTI group. The other 53 were the non-UTI group. Complete clinical evaluations were available for all 77, and those data were used to identify risk factors for UTI using univariate and multivariate logistic regression analysis.Results:The univariate analysis showed that age, side of paralysis, consciousness dysfunction, Brunnstrom staging of the lower extremity, tracheotomy, indwelling catheter, lung infection, white blood cell count, neutrophil percentage, serum natrium, uric acid, D-dimer level and fibrinogen were all significant predictors of UTI. The multivariate analysis identified age, right side hemiplegia and D-dimer level as useful predictors.Conclusions:Advanced age and a high D-dimer level are independent risk factors for UTI after ICH, while hemiplegia on the right side is a protective factor.

OBJECTIVE:To study the improvement effect and mechanism of Meng medicine Wuwei Shaji powder(WSP)on smoke-induced lung inflammation injury in mice. METHODS:ICR mice were randomly divided into blank group(normal saline), model group (normal saline) and WSP group (2 g/kg). Mice in model group and WSP group received passive smoking to induce model of lung inflammation injury,and intragastrically administrated relevant medicine when modeling,once a day,for 28 d. Af-ter administration,enzyme-linked immunosorbent assay was used to detect the tumor necrosis factor α(TNF-α),interleukin-1β(IL-1β),IL-6,IL-10 levels in bronchoalveolar lavage fluids(BALF);the pathological changes of lung tissue were observed by op-tical microscope after hematoxylin-eosin staining;Western blot was adopted to detect the protein expressions of extracellular sig-nal-regulated kinase (ERK1/2),phosphorylated ERK1/2 (p-ERK1/2),p38 mitogen-activated protein kinase (p38 MAPK),phos-phorylated p38 MAPK(p-p38 MAPK),nuclear factor kappaB p65(NF-κB p65)and phosphorylated NF-κB p65(p-NF-κB p65)in lung tissue of mice. RESULTS:Compared with blank group,TNF-α,IL-1β,IL-6 levels in BALF in model group were obviously increased (P<0.01);lung tissue showed significant inflammatory lesions;and the protein expressions of p-ERK1/2, p-p38 MAPK,p-NF-κB p65 in lung tissue were obviously increased (P<0.01). Compared with model group,TNF-α,IL-1β levels in BALF in WSP group were obviously decreased(P<0.05);inflammation injury in lung tissue was obviously improved;and protein expressions of p-p38 MAPK and p-NF-κB p65 in lung tissue were obviously decreased (P<0.05). CONCLUSIONS:WSP shows improvement effect on smoke-induced lung inflammation injury in mice,which might be by blocking the p38 MAPK,NF-κB p65 phosphorycation to inhibit the high expression of inflammatory factors as TNF-αand IL-6.

Objective:To observe risk factors for lung infection (LI) after cerebral hemorrhage (ICH).Methods:A total of 118 patients with ICH were retrospectively analyzed. Among them, 63 were diagnosed with an LI according to clinical manifestations and X-ray or CT on admission. They were selected into an LI group, while the rest formed the non-LI group. Gender, age, duration of disease, side of paralysis, position and type of ICH, complications, cognitive disorders, consciousness, dysphagia, motor function, and serum levels of albumin, sodium, potassium, calcium and magnesium were recorded on the second day after admission. The risk factors for LI were analyzed using univariate and multivariate logistic regression analysis.Results:Age, duration of disease, side of paralysis, position and type of ICH, tracheotomy, urinary tract infection, cognitive impairment, dysphagia, motor function, and serum levels of albumin, sodium, calcium, and magnesium were all significant predictors of LI after an ICH. Multivariate logistic regression analysis showed that right side hemiplegia, bilateral paralysis, subarachnoid hemorrhage, urinary tract infection, and serum magnesium are all significant predictors.Conclusions:Right or bilateral paralysis, subarachnoid hemorrhage and urinary tract infection are independent risk factors for LI after an ICH. High serum magnesium within the normal range can reduce the incidence of LI.
