Objective To investigate the signaling mechanisms underlying synergistic induction of MUC5AC mucin by nontypeable Haemophilus influenzae(NTHi)and epidermal growth factor (EGF).Methods The expression of MUC5AC was measured by real-time quantitative polymerase chain reaction(PCR)and Luciferase assay.Western blot was performed to examine the synergistic induction of phosphorylation of P38,extracellular signal-regulated kinase(ERK)and P21-activated kinase(PAK)4 or the effect of dominant negative mutant of PAK4 on the synerglstic induction of phosphorvlation of P38 mitogen-activated protein kinase(P38MAPK)and ERK in HM3 cells treated with NTHi and EGF.Luciferase asgay was also performed to examine the effect of P38,ERK inhibitors or dominant negative mutants of P38MAPK and ERK on synergistic enhancement of NTHi-induced MUC5AC up-regulation by EGF at transcriptional level.Real-time quantitative PCR was performed to examine the effect of PAK4 siRNA on synergistic induction of NTHi-induced MUC5AC up-regulation by EGF.ResuIts NTHi induced MUC5AC mucin expression at both mRNA and transcriptional levels.Synergistic induction of phosFIhorylation of P38MAPK,ERK and PAK4 were observed in HM3 cells treated with NTHi and EGF.Either SB203580,a specific inhibitor for P38MAPK or PD98059,a specific inhibitor for ERK inhibited synergistic induction of MUC5AC at transcription level.Furthmore, overexpressing dominant negative mutant of P38MAPK and ERK also inhibited synergistic induction of MUC5AC at transcription level. PAK4 siRNA inhibited the synergistic induction of MUC5AC by NTHi and EGF. Overexpressing dominant negative mutant of PAK4 also reduccd synergistic induction of phosphorylation of P38 and ERK. Conclusion Synergistic induction of MUC5AC mucin by NTHi is up-regulated by EGF via PAK4-dependent P38MAPK and ERK pathways.

Objective To explore the effects of parents'participatory functional training on the prognosis of newborn babies with hypoglycemic brain injury.Methods Functional training was given to 32 parents of newborn babies with hypoglycemic brain injury and then carried out on their babies for three months.The clinical symptoms and clinical efficacy of the babies and parents'satisfaction with nursing care were then observed.Results The clinical symptoms of the babies were improved significantly after training, and the parents had significantly higher satisfaction with nursing care as compared to pretraining (p<0.01).After training, 22 babies showed significant clinical efficacy (68.75%) , 8 babies had the targeted effect (25.00%);and the total effect rate was 93.75%.Conclusion Parents'participatory functional training helps to improve the prognosis of newborn babies with hypoglycemic brain injury and reduce the incidence of neurological sequelae.

Objective:To investigate the incidence and related factors with sarcopenia in maintenance hemodialysis patients.Methods:A total of 131 patients with non-hospitalized maintenance hemodialysis who had been maintained for at least 3 months and in a stable condition were enrolled in a cross-sectional study.Bioelectric impedance analysis (BIA) method was employed to examine the muscle mass.MQSGA questionnaire was used to evaluate patients'nutrition status as well as related laboratory indicators.Logistic regression was used to analyze the risk factors of sarcopenia in MHD patients.Results:The incidence of sarcopenia in 131 MHD patients was 41.22％ (54/131).Significant differences were observed in gender,duration of hemodialysis,hs-CRP and the score of M(Q)SGA between the two groups.The incidence of sarcopenia in male was 43.67 times compared with female.And with the increase of hs-CRP levels and MQSGA score,the incidence of sarcopenia was increased as well (P ＜0.05).Conclusion:Sarcopenia has a high incidence in MHD patients,and male,micro-inflammatory state and malnutrition were the risk factors.

Objective To improve the reliability of the core database system by ameliorating the scheme of the server system architecture. Methods Combined with practice of the hospital informatization, the security and potential hole of the database server system were analyzed and evaluated. Results Aimed to deal with the security hidden-trouble, a mini-server was adopted instead of PC server, while SAN(Storage Area Network) was utilized instead of RAID-5, and mirror copy technique was used to implement the real-time hot copy of the data. Conclusion Consequently the reliability of the system has been greatly improved.

Objective: To explore early diagnostic value of combined detection of ischemia-modified albumin and other biochemical markers for acute coronary syndrome (ACS). Methods: A total of 156 patients, who received treatment within 4h because of chest pain onset, were divided into ACS group (n=112) and non-ischemic chest pain group (NICP group, n=44) according to coronary angiography (CAG). Blood sample was taken within 4h and during 4~8h after chest pain to measure cardiac biochemical markers, including ischemia-modified albumin (IMA), LDH, CK, CK-MB and cardiac troponin I (cTnI), comprehensive analysis was performed by detected results of above biochemical markers and CAG. Results: For diagnosis of ACS, within 4h after onset IMA possessed highest sensitivity (87.50%) and highest accuracy (80.77%), cTnI possessed highest specificity (95.45%); In 4～8h IMA still possessed highest sensitivity (91.07%), cTnI still possessed highest specificity（97.73%）, CK（85.90%），and IMA（85.25%）possessed highest accuracy （both CK and IMA had no significant difference）; According to comprehensive analysis, regardless of within 4h or during 4~8h after chest pain, IMA possessed highest sensitivity and highest accuracy, cTnI possessed highest specificity. Within 4h after chest pain, detection of IMA combined above-mentioned other four indexes increased sensitivity (89.28%), specificity （95.45%） and accuracy （91.02%）to highest level. Conclusion: For diagnosis of ACS, IMA possesses highest sensitivity and highest accuracy, cTnI possesses highest specificity; IMA combined above-mentioned other four indexes may increase sensitivity, specificity and accuracy to highest level.

Objective To explore the feature of balance function and falling risk in the elderly knee osteoarthritis patients with single knee pain or double knees pain. Methods 30 elderly knee osteoarthritis patients without pain, 30 with single knee pain and 32 with double knees pain were tested with timed up and go test (TUG), postural stability (PS), limits of stability (LOS) and dynamic fall index (DFI). Results There was significant difference in the elderly between no pain and single or double knee pain (P<0.05) in TUG, but not between the single knee pain and double knees pain (P>0.05). There was no significant difference in the elderly between single knee pain and no pain (P>0.05) in PS, but was between double knees pain and the other 2 groups (P<0.05). There was significant difference between no pain and single or double knee pain (P<0.05) in LOS, but not between single knee pain and double knees pain (P>0.05). There was significant difference between no pain and single or double knee pain (P<0.05) in DFI, and between single knee pain and double knees pain (P<0.05). Conclusion The elderly osteoarthritis patients with single knee pain are in high falling risk with their dynamic balance injury, while those with double knees pain are in higher falling risk with their static and dynamic balance injury.
