Objective To study the clinical significance of C-reactive protein(CRP),neutrophil granulocyte ratio(N% ) in acute exacerbations of hospitalized patients with chronic obstructive pulmonary disease ( COPD ). Methods The serum CRP levels,the gross of N% were detected of the same 71 patients with acute exacerbations of COPD before treatment and after getting better. And the correlations among above-mentioned indexes,the days counter before getting better and the days counter during hospitalization were observed. Results (1) The levels of CRP and N% of patients after getting better were significantly lower than those before treatment(P ＜0. 01). (2) There was a significant correlation between N% and the days counter before getting better(r =0.240,P ＜0.05) and also a significant correlation between the days counter before getting better and the days counter during hospitalization (r = 0. 567, P ＜0.01). Conclusion The serum CRP level and N% were objective markers in estimating pulmonary infection in COPD patients with acute exacerbations. And N% was a reliable indicator of judging the days counter before getting better and better than CRP.

Objective To study the changes of blood gastrointestinal hormones concentration and effect of early feeding in premature infants on it. Methods Seventy-two premature infants were divided into 4 groups: self-sucking (group Ⅰ),tube feeding (group Ⅱ),minimal enteral nutrition (MEN, group Ⅲ), non-nutritive sucking (NNS, group Ⅳ). The plasma motilin and serum gastrin were measured within 12 hour before enteral feeding, on day 3 and day 7 of life by radioimmunoassay. 16 full-term neonates were studied as control. Results (1)The serum concentration of gastrin in premature infants before enteral feeding, on day 3 and day 7 were (61?24)ng/L,(93?37)ng/L,(126?45) ng/L respectively, which were significantly lower than that of control(126?30) ng/L,(135?34)ng/L,and (178?46)ng/L,(P

Objective To explore the effect of Xiao Ban Xu, a compound Chinese traditional medicinal prescription, on the expression of collagenⅠand Ⅲ of keloid fibroblasts in vitro. Methods Six samples of keloid fibroblasts (KFB) and 6 samples of normal fibroblasts (NFB) entered the study as experimental and control groups, respectively. With the application of Xiao Ban Xu (10?g/ml), the fibroblast culture system and the ABC immunocytochemical staining method were used to investigate the expression of collagenⅠand Ⅲ of KFB and NFB. Results The density of the staining of collagenⅠand Ⅲ in the experimental group was much higher than that in the control group, with (7675 4?825 5 vs 2305 2?320 4 and 10595 2?1311 5 vs 2434 8?356 9; t =13 37 and 12 66, P =0 00004 and 0 00005) or without (11113 1?1304 9 vs 3519 6?236 0 and 11157 7?1300 3 vs 2626 5?426 3; t =14 42 and 13 47, P =0 00003 and 0 00004) the addition of Xiao Ban Xu. Compared with blank control group, the density of the staining of collagenⅠand Ⅲ was degenerated greatly in the experimental group after 48 hours of application of Xiao Ban Xu (7675 4?825 5 vs 11113 1?1304 9 and 10595 2?1311 5 vs 11157 7?1300 3; t =10 31 and 4 68, P =0 0001 and 0 0054). Furthermore, the inhibition ratios of collagenⅠwas 30 7%, and the one of collagen Ⅲ 5 1%, in the experimental group. Conclusions The expression of collagenⅠand Ⅲ of keloid fibroblasts in vitro may be significantly more intensive than the one of normal skin fibroblasts. It seems that the expression of collagenⅠand Ⅲ, especially collagenⅠ, in keloid fibroblasts and normal skin fibroblasts in vitro may be suppressed greatly by the application of Xiao Ban Xu.

Objective To understand the level of neonatal pain knowledge and attitudes of neonatal and obstetric department nurses, in order to supply the clinical basis for neonatal pain management. Methods Self-designed questionnaires to fill out on-site were distributed to 107 neonatal and obstetric department nurses (of which 40 were from neonatal department, 67 from obstetric department) for neonatal pain knowledge and attitudes. Results About question of neonatal pain, the average percentage of correct answers in the neonatal group was 75.5%, higher than 66.3% of the obstetric group, in the neonatal group, correct rate of seven questions was more than 80%,while in the obstetric group the correct rate of only one question was more than 80%, and 5 questions correct response rate was significantly lower than that of the neonatal group, the difference was significant. All nursing staff considered it essential or necessary to carry out the nursing knowledge of pain-related training. 95.0%(38/40) of neonatal nurses believed that they could properly assess the extent of neonatal pain, but only 83.6% (56/67) for the obstetric group, the difference between the two groups was significant. 97.5% (39/40) of neonatal nurses believed that they could make the right judgments on neonatal crying, and only 85.1%( 57/67) in the obstetric nurses, the difference between the two groups was significant.Conclusions Neonatal pain has gradually been recognized and paid attention to by the clinical front-line medical staff, they believe that it is necessary to receive training on neonatal pain, knowledge of neonatal pain of neonatal nurses is better than obstetric nurses.

Objective To investigate the respiratory pathogen distribution characteristics in children with acute respiratory disease(ARD).Methods Distribution of respiratory pathogen in 28 600 children with ARD,treated from January 2011 to December 2014 in this hospital,were analyzed.Results Among the 28 600 children,12 162 cases were pathogen positive,including 7 704 cases(63.34%) with single pathogen infection and 4 458 cases(36.66%) with more than two kinds of pathogens infection.Time,season,sex and age distribution of pathogen infection were with statistical difference(P<0.05).There was significant difference in infection rate of pathogens between different time(P<0.05).Infection rate of Mycoplasmal pneumonia(MP) was the highest,and the infection rate of MP and influenza B virus(IFB) increased year by year.Except Legionella pneumophila(LP),the season distribution of infection rate of MP,Coxiella burneti(COX),Chlamydia pneumoniae(CP),adenovirus(ADV),respiratory syncytial virus(RSV),influenza A virus(IFA),IFB and parainfluenza virus(PIVs) were with statistical difference(P<0.05).The infection rate of MP and IFB were higher in the whole year.Conclusion Distribution of respiratory pathogen in children with ARD might be related with the changes of gender,age and season.Detection of respiratory infection pathogen could be with guiding value for clinical diagnosis and drug selection.

Objective To study the effects of electromagnetic field (EMF) on the activation of extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK) pathways in mesenchymal stem cells (MSCs) and their interaction, and to explore the cellular signal transduction mechanism of the biological effects induced by EMF.Methods The 3rd-passage rat bone marrow MSCs were randomly divided into a control group, an EMF group, an EMF + PD98059 group and an EMF + SB202190 group.Cells in the EMF group were cultured in the electromagnetic field, those in the EMF + PD98059 and EMF + SB202190 groups cultured in the electromagnetic field after PD98059 or SB202190 was added, and those in the control group were cultured normally.Different groups of cells were exposed to electromagnetic fields (15 Hz, 1 mT, sine wave form) for different exposure duration.The activated phosphorylated and non-phosphorylated p38MAPK were measured using Western blotting analysis with their specific corresponding antibodies.The alkaline phosphatase (ALP) activity in cells in different groups was detected according to the instructions of ALP kit.MTT assay was applied to investigate the proliferation of cells.Results Electromagnetic fields could rapidly induce the activation of p38 MAPK (P ＜ 0.05) and the phosphorylation of p38 MAPK elevated after 15 min exposure to EMF.The phosphorylation of p38 MAPK was significantly lower in the EMF + SB202190 group than that of the EMF group.After 5 days of EMF exposure, the ALP activity of cells was significantly improved, and the effect could be inhibited by SB202190.The bone marrow mesenchymal stem cells proliferation increased significantly after being exposed to EMF for 3 days, and it could not be blocked by SB202190.Phosphorylation of ERK and MAPK increased significantly when the p38 MAPK pathway was blocked by SB202190 and exposed to EMF for 5 minutes, and it also increased significantly when the ERK MAPK pathway was blocked by PD98059 and received 30 minutes of EMF exposure.Conclusion EMF can quickly activate ERK and p38 MAPK pathways to induce cell proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells.Moreover, in EMF there is a mutual interference between ERK and p38 MAPK pathways.

Objective To explore the expression and significance of N-cadherin in urothelial bladder cancer and analyse its relation to clinicpathologic and prognosis of bladder cancer.Methods The expression of N-cadherin in 145 urothelial bladder cancer and 25 normal bladder tissues was detected by immunuhistochemisty,and correlations between N-cadherin and clinicopathologic features were analysed.Results The positive rate of N-cadherin protein was significantly higher in bladder cancer than in normal bladder tissue (P＜0.01).The positive rate of N-cadherin protein was 38.6％ in G1 bladder cancer,58.4％ in G2-G3 bladder cancer,and its difference was significant (P =0.028).The expression was significantly lower in non-muscle-invasive bladder cancer than in muscle invasive bladder cancer (45.7％ vs 64.7％,P=0.029).The muscle-invasive bladder cancer patients were followed up 4-103 months.Among those,the overall survival with positive expression of N-cadherin protein was 24.2％ (8/33),and the overall survival with negative expression of N-cadherin protein was 66.7 ％ (12/18).Kaplan-Meier analysis showed the positive expression of N-cadherin was significantly associated with overall survival of patients with muscle-invasive-bladder cancer (P=0.002 2).Multivariate Cox analysis showed that N-cadherin expression was an important prognostic factor.Conclusions The expression of N-cadherin protein was high in bladder cancer.The detection of the expression of N-cadherin protein is associated with the diagnosis and prognosis of bladder cancer.
