Objective To evaluate the levels of high-sensitivity-CRP(hs-CRP),interleukin-10(IL-10) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods Fifty cases with obstructive sleep apnea-hypopnea syndrome from Jul.2012 to Dec.2013 in the People's Hospital of Pudong New Area were selected as our subjects,of which,22 patients were with mild-moderate OSAHS and 28 patients were with severe OSA.Twenty-seven health people were served as control group.The levels of hs-CRP,IL-10 were measured.Information of sleep study and other clinical characteristics were collected.Results There were no significant differences in terms of age,hip circumference and waist-to-hipratio (WHR) among three groups (P ＞0.05).Body mass index (BMI),neck circumference,waist circumference,Apnea-Hypopnea Index (AHI),the lowest arterial oxygen saturation(SaO2％) and hs-CRP in mild,severe OSA and control group were (28.01 ±3.41),(28.55±2.87) and (5.51±3.28) kg/m2,(41.18±4.37),(41.46±3.32) and (38.76±2.66) cm,(101.86±8.05),(102.32±7.97) and (94.56±10.25) cm,(44.55±16.26),(10.54±7.08) and (2.02 ±1.51) time/h,(85.05±6.40)％,(72.85±15.07)％,(88.59±3.43)％,(8.35±2.71),(9.19±2.85),(7.06 ± 1.30) mg/L,and the differences were significant(P＜0.05).In patients with OSA,SaO2％ was related to BMI (r =-0.274,P =0.027) and AHI (r =-0.651,P ＜ 0.001).Level of hs-CRP was associated with AHI (r =0.336,P =0.006) and BMI (r =0.247,P =0.047),and weakly associated with IL-10 concentrations.Conclusion Levels of hs-CRP is an important inflammation marker of OSAHS severity.However,levels of IL-10 shows an increasing in mild-moderate OSA patients,then decreasing in patients with severe OSA.

Objective To investigate the injury characteristics and prognostic risk factors of patients with craniocerebral injury so as to provide some suggestions for the improvement of medical prevention,intervention and treatment measures.Methods Trauma database system was applied to collect the medical records of 661 patients with traumatic brain injury admitted to the Department of Neurosurgery of 105th Hospital of Hefei in 2009.Their general conditions,injury characteristics and outcomes were analyzed and the risk factors affecting their outcomes were investigated by Logistic regression analysis.Results Of the patients with craniocerebral injury,the males accounted for 70％ (463/661).The patients at 45 years old or so had the highest incidence of craniocerebral injury.Patient number in the second half of one year was 1.65 times more than that in the first half of one year (412/249 ).Most patients were injured from traffic accidents (87.7％,580/661 ) and 512 patients (77.5％) suffered from multiple injuries.ISS,injury causes,age and injury incidence quarters showed close correlation with the final outcome.Conclusions The patients with craniocerebral injury demonstrates distinctive characteristics in aspects of gender,age,incidence time,injury causes,and multiple injuries,but the ultimate outcomes are related to the injury severity,injury causes,age and other factors.

The aim of the current study is to investigate the effect of visfatin on cardiomyocyte hypertrophy. Cultured H9c2 cardiomyocytes were exposed to visfatin at different concentrations for different periods of time, and the markers of cardiomyocyte hypertrophy were detected. Moreover, pravastatin, the inhibitor of endoplasmic reticulum stress (ERS) or thapsigargin, an ERS agonist was used respectively to pre-treat the cells before visfatin stimulation. F-actin staining was performed to measure the cell surface change. The mRNA expressions of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and ERS markers including glucose-regulated protein 78(GRP78), C/EPB homologous protein (CHOP) and activating transcription factor 6 (ATF6) were assessed by real time RT-PCR. The change of protein level of GRP78 and CHOP was detected by Western blot. The experimental data demonstrated that exposure to 100 or 150 ng/mL concentrations of visfatin for 24 h, or 100 ng/mL of visfatin for 24 or 48 h, significantly increased the expression of markers for cardiomyocyte hypertrophy. Visfatin stimulation provoked ERS in H9c2 cells. Furthermore, pre-treatment with pravastatin partially inhibited the visfatin-induced mRNA expression of ANP and BNP in H9c2 cells, whereas thapsigargin promoted the visfatin-induced expression of cardiomyocyte hypertrophy markers. The results suggest that visfatin might induce cardiomyocyte hypertrophy via ERS -dependent pathways.

Objective To analyze the levels and clinical significances of IL-18,Caspase-3 and nerve tissue-specific protein S-100B at different disease extent and different stages of infants with hypoxicischemic encephalopathy (HIE).Methods This study was clinical experimental studies.Sixty-seven infants with HIE (23 cases of mild HIE,23 cases of moderate HIE,21 cases of severe HIE) from February 2008 to June 2009 in Hebei Children's Hospital were enrolled.The levels of IL-18,Caspase-3 and S-100B protein in all samples were measured at acute phase (1 d,3 d) and recovery phase (7 d) by ELISA method.Twenty healthy full-term neonates were selected as the normal control group.Multi-factor analysis of variance and Pearson correlation test was used for statistical analysis.Results The levels of the three indicators in the moderate and severe group were higher than the normal control group.In the moderate group,IL-18 levels were(132.15 ± 9.87),(150.31 ± 15.04) and (87.91 ± 9.93) ng/L,Caspase-3 levels were (5.79 ±0.64),(7.36 ± 1.57)and (3.79 ±0.61) μg/L,S-100B levels were(6.82 ±0.61),(9.62 ± 1.29) and (10.76 ± 1.64) μg/L.In the severe group,IL-18 levels were (160.23 ± 16.03),(189.86 ± 18.32) and (107.35 ± 13.02) ng/L;Caspase-3 levels were (6.86 ± 1.02),(9.54 ± 1.43) and (5.25 ± 0.71) μg/L;S-100B levels were(8.90 ± 0.32),(12.54 ± 0.89)and(13.53 ± 0.75) μg/L.In the normal control group,IL-18 levels were (71.08 ± 11.52),(72.53 ± 11.05) and (71.93 ± 11.30) ng/L; Caspase-3 levels were (2.84 ± 0.52),(2.98 ± 0.53) and (2.87 ± 0.52) μg/L; S-100B levels were (1.50 ± 0.25),(1.62 ±0.30)and(1.53 ±0.29) μg/L IL-18 levels,Caspase-3 levels and S-100B levels in severe group were higher than the moderate group and the mild group were higher than the mild group.IL-18 levels were (73.46 ± 4.77),(77.59 ± 4.02) and (72.87 ± 6.92) ng/L ; Caspase-3 levels were (3.13 ± 0.31),(3.63±0.40) and (3.26 ±0.45) μg/L;S-100B levels were(3.68 ±0.40),(5.851 ±0.63) and(6.95 ± 0.58) μg/L in the mild group.S-100B levels in the mild group were higher than that in the normal control group.The IL-18 and Caspase-3 levels were risen in the third day to the first day in the acute phase of the moderate group and severe group,decreased in the recovery phase.Serum S-100B protein levels in the acute and recovery phase increased gradually,and there was no correlation between the three indicators (r-=0.321,0.14,0.48,P=0.438,0.974,0.911 respectively).Conclusions IL-18,Caspase-3 and S-100Bwere involved in the pathophysiological process of HIE.The levels were closely related to the severity and disease progression of HIE,the severer of the illness,and the higher of the levels.Dynamic monitoring the changes of the three indicators may contribute to an early diagnosis,condition monitoring and prognosis of HIE.

Objective To study the effect of skin protective membrane, semi-transparent dressing and combination of the two in critically ill patients with incontinence associated dermatitis (IAD) skin protection. Methods A total of 114 patients who were admitted into ICU and NICU of Hebei Xingtai People′s Hospital from December 2013 to November 2014 were selected. These subjects were divided into 3 groups randomly. All three groups received routine skin care, on this basis, skin protective membrane group (34 cases) used skin protective membrane for skin protection, semi-transparent dressing group (40 cases) adopted semi-permeable dressing for skin protection, while the combination group (40 cases) used skin protective membrane combined with semi-transparent dressing for skin protection. The incidence, occurrence and severity of IAD in the three groups were compared. Results The incidence rate of IAD in the combination group was 20.0%(8/40), 20.6%(7/34) in the skin protective membrane group, and significantly lower than 47.5% (19/40) in the semi-transparent dressing group, the difference was significant ( χ2=9.201, P<0.05). The occurrence time of IAD in the combination group was (4.75±0.46) days, which was significantly longer than those of the skin protective membrane group [(3.86±1.35) days] and the semi-transparent dressing group [(2.74±0.73) days], the difference was significant (F=17.120, P < 0.05). The IAD severity of the combination group scored 3.63 ±0.92, which was significantly lower than those of the skin protective membrane group (5.29±1.11) and the semi-transparent dressing group (6.74±1.79), the difference was significant (F=12.240, P<0.05). Conclusions Skin protective membrane combined with semi-transparent dressing have priority in decreasing IAD incidence rate, and delaying the occurrence time of IAD, and relieving the severity of IAD, which is better than either of the two.

Objective To study the pathogens and their drug susceptibility of septic arthritis of hip in children. Methods Prior to the antibiotic treatment, pus was extracted for bacterial culture under aseptic operation. The pathogenic bacterium was identified and drug susceptibility was analyzed using a fully automated bacterial identification/drug susceptibility system. Results A total of 68 pathogens were isolated, in which 42 were Gram-positive bacteria, 23 were Gram-negative bacteria and 3 were fungi. The results showed differences in the bacterial types of hip septic arthritis in children with different ages (5 days to 13 years). For newborns (less than 1 month), the most common pathogen was Klebsiella pneumoniae; for the ages of 1 month to 13 years old, the most common pathogen was Staphylococcus aureus. The results of drug susceptibility tests showed that Gram-positive bacteria were highly susceptible to vancomycin, teicoplanin and linezolid;the resistance of Staphylococcus aureus to penicillin was up to 96％; and Klebsiella pneumoniae, Escherichia coli, Haemophilus influenzae, Enterobacter cloacae and Salmonella were highly sensitive to meropenem and imipenem. Conclusion In the antimicrobial drug treatment of children with hip septic arthritis, the etiology sample should be collected for drug susceptibility analysis. Empirical drug therapy strategy should be applied in the absence of the analysis results. Sensitive antibiotic drug therapy should be used after obtaining reliable etiological diagnosis and drug susceptibility results, and simultaneously taking the age into consideration.

The aim of this study is to investigate the effects of pulsed electromagnetic fields (PEMFs) on the induction of rat bone marrow mesenchymal stem cells (rBMSCs) to differentiate into cardiomyocytes-like cells in vitro. rBMSCs were randomly divided into PEMFs groups, 5-Azacytidine (5-Aza) groups and control groups. PEMFs groups were exposed to 50 Hz, 1 mT PEMFs for 30 min every day, lasting for 10 d, 15 d and 20 d, respectively. 5-Aza groups were induced by 10 micromol/L 5-Aza for 1 day, then the medium was changed to complete medium without 5-Aza. And control groups were only cultured with complete medium, rBMSCs growth status and morphological features were observed by inverted phase microscope every day. The mRNA expressions of cardiac troponin T (TNNT2) and alpha-actinin (ACTN2) were determined by Real-Time PCR. The results showed that rBMSCs were spindle, polygon or fusiform in control groups. The cells gradually got longer and grew close together after being stimulated by PEMFs and 5-Aza, and with the extension of induction time, the tendency became obvious. At 20th day after PEMFs or 5-Aza treatment, rBMSCs gathered like a long chain, got much longer obviously at the high magnification, and some of them even fused with their neighbors. Compared with control groups, the levels of TNNT2 mRNA expression in 5-Aza groups were 19.40 fold (P < 0.01), 21.02 fold (P < 0.01) and 2.38 fold at 10 d, 15 d, 20 d and the levels of ACTN2 mRNA expression in 5-Aza groups were 6.64 fold (P < 0.01), 6.67 fold (P < 0.01) and 0.76 fold at 10 d, 15 d, 20 d. However, the levels of TNNT2 mRNA expression in PEMFs groups were 15.78 fold (P < 0.01), 6.73 fold (P < 0.05) and 2.73 fold (P < 0.01) of control groups at 10 d, 15 d, 20 d and the levels of ACTN2 mRNA expression in PEMFs groups were 4.93 fold (P < 0.01), 1.89 fold and 0.64 fold, respectively. Compared with 5-Aza groups, the levels of TNNT2 mRNA expression in PEMFs groups were 0.81 fold, 0.32 fold (P < 0.01) and 1.15 fold at 10 d, 15 d, 20 d and the levels of ACTN2 mRNA expression in PEMFs groups were 0.74 fold, 0.28 fold (P < 0.01) and 0.83 fold at 10 d, 15 d, 20 d. PEMFs could contribute to the induction of rat marrow rBMSCs to differentiate into cardiomyocytes-like cells in vitro, and the best exposure time might be 10 days, but further investigation is still needed.
