Results The expression of KLK4 in ovarian cancers was significantly higher than that of the control group(P

Objective To compare the efficacy of internal fixation with non-operative treatment of traumatic flail chest combined with sternal fracture.Methods A retrospective review was made on 102 patients with traumatic flail chest combined with sternal fracture treated from January 2007 to January 2014.There were 71 patients in operation group and 31 patients in non-operation group.Operation group was allocated to pure titanium rib plating (Group Ⅰ,22 cases),porous titanium screw fixation (Group Ⅱ,20 cases),and nickel-titanium memory alloy sternal rib plating (Group Ⅲ,29 cases).Rib traction was performed in non-operation group.Clinical results and incidence of complications were compared between the two groups.Results At 24 and 72 hours,operation group was superior over non-operation group with regard to HR [(100.4 ± 9.5) times/min vs (105.2 ± 10.1) times/min,(92.1 ± 9.9) times/min vs (102.1 ± 9.2) times/min],MAP [(97.7 ± 14.5) mmHg vs (91.0 ± 13.3) mmHg,(112.5 ± 15.2) mmHg vs (93.1 ± 13.8)mmHg] and CVP [(7.8 ±3.7)cmH2O vs (9.4 ±3.8)cmH2O,(6.2 ±2.9)cmH2O vs (9.1 ±3.2) cmH2 O] (P ＜ 0.05).Duration in ICU [(5.1 ± 0.8) days vs (9.3 ± 1.1) days],ventilation time [(4.5 ±1.0)days vs (8.2 ± 1.4)days],hospitalization time [(14.6 ±3.5)days vs (23.3 ±4.4)days] and incidence of complications were significantly lower in operation group than in non-operation group (P ＜ 0.05).Two months after discharge,tidal volume (VT) [(0.52 ±0.04)L vs (0.40 ±0.03)L],inspiratory capacity (IC)[(1.99 ±0.45)L vs (1.22 ±±0.33)L],forced vital capacity (FVC) [(3.52 ±0.51)L vs (2.44 ±0.42)L],total lung capacity (TLC) [(5.41 ±0.82)L vs (3.72 ±0.56)L] and forced expiratory volume in one second (FEV1) [(2.80 ± 0.43) L vs (1.95 ± 0.50) L] showed significantly better results in operation group than in non-operation group (P ＜ 0.05).Operation time,intraoperative bleeding and daily drainage volume were (38.8 ±9.2)min,(43.5 ±7.6)ml and (10.9 ± 1.1)ml in Group Ⅱ versus (62.5 ± 10.1)min,(100.0 ± 10.5) ml and (26.8 ±3.1)ml in Group Ⅰ and (49.3 ±9.6)min,(61.4 ±8.3)min and (19.8 ±1.6)ml in Group Ⅲ (P ＜ 0.01).Conclusion For traumatic flail chest combined with sternal fracture,the internal fixation should be done as early as possible so as to reduce incidence of complications.Relatively,porous titanium screw fixation has better clinical outcome.

ObjectivesTo study the treatment timing and method of glucocorticoids in the treatment of abdominal type Henoch-Sch?nlein purpura (HSP).MethodsA total of 201 children with abdominal type HSP hospitalized from September 2009 to April 2013 received either conventional glucocorticoids treatment or rapid titration treatment of glucocorticoids based on the same basic therapy. According to the treatment timing and method of glucocorticoids, all patients were divided into 4 groups including early convention group (n=46), late convention group (n=44), early titration group (n=56) and late titration group (n=55). The duration from the appearance of gastrointestinal symptoms to using glucocorticoids less than or equal to three days was deifned as early treatment and more than three days was deifned as late treatment. The patients in two convention groups (early and late) were treated with methylprednisolone (2-6mg/kg per day).The patients in two titration groups (early and late) received rapid titration of methylprednisolone from an initial low dose of 2mg/kg per day to the ifnal target dose. The gastrointestinal symptoms were evaluated every 12 hours. If the gastrointestinal symptoms were not alleviated, an additional dosage of methyl-prednisolone was given. On the next day, the total dose of methylprednisolone in previous 24 hours was used as the initial dose. The dosage was increased in such a way till the gastrointestinal symptoms disappeared and this dosage was remained for 3 days. Then the dosage was gradually reduced to the maintenance dose and stopped. If the gastrointestinal symptoms were relapsed, the patients were treated again. A follow-up of 3-6 months was performed. The dosage, recurrence of symptoms and the side effects were compared among four groups.ResultsThe time of remission, target dose of glucocorticoids, total dose of glucocorticoids, recurrence rate, incidence of severe symptoms and Henoch-Schonlein purpura nephritis were signiifcantly different among four groups (P<0.05). The curative effect was best in early titration group and worst in late convention group.ConclusionsIn the treatment of abdominal type HSP, early titration treatment with glucocorticoids can signiifcantly relieve the gastrointestinal symp-toms and reduce the total dosage of glucocorticoids.

Results (1) The P-selectin level of pre-delivery in moderate and severe PIH patients w as (66?24)?g/L and (80?30)?g/L, it was (49?15)?g/L in the control group ( both P

Objective To study the dynamic variation of mbisoenzyme of creatine kinase(CK-MB) in the infected course of respiratory syncytial virus and explore the value of CK-MB/CK in the diagnosis of myocardial damage.Methods A total of 577 pediatric patients (317 males,260 females,aged 2 ～ 18 months) with CK-MB/CK ＞5％ from 2010 to 2013 were enrolled in this study (44 complicated by myocardial damage).Five hundred and thirty-three patients with high values CK-MB simply were randomly divided into treatment group (n =243) and control group(n =290).The dynamic variation of CK-MB were investigated.The diagnosis analyzed by receiver operating characteristic (ROC)curve was used to explore the predictive value of differential diagnosis between the pediatric patients with myocardial damage and without myocardial damage.Results Approximately 46.5％ of cases with rotavirus diarrhea had higher CK-MB and 3.5％ of cases had myocardial damage.The time of CK-MB achieved peak and anomalous duration was different between the cases with myocardial damage and without myocardial damage.There was no statistical significance between the cases with or without protecting myocardial(P ＞ 0.05).The ROC curves were constructed with area under the ROC curves of 0.663 (95 ％ CI 0.578,0.747).Conclusion The blood levels of CK-MB in children with respiratory syncytial virus infection existed obvious dynamic variety,which contributed little value to the diagnosis of myocardial damage.

Objective To study the clinical application value of humidified high flow nasal cannula(HHFNC) on bronchitis in children.Methods Total 85 cases of bronchitis that needed oxygen therapy in our department from Oct 2015 to Feb 2016 were randomly divided into three groups,HHFNC group,NCPAP group and nasal cannula oxygen group(control group).According to the blood gas results,FiO2 was adjusted to maintain PaO2 in 50~70mmHg(1mmHg=0.133kPa),TcSO2 90% to 95%.The main symptoms and signs(wheezing,shortness of breath,three depression sign,wheezing rale) disappeared time,length of oxygen inhalation and stay,the change of PaO2,PaCO2,respiratory rate were compared among the three groups.Results Compared with control group,the clinical symptoms and signs disappeared time and length of oxygen inhalation and stay were significantly shorter in HHFNC group(P<0.05).The recovery of blood gas and respiratory rate in HHFNC group were better than those in control group(P<0.05).No statistically significant differences existed between HHFNC group and NCPAP group(P>0.05).Conclusion HHFNC can significantly improve the clinical symptoms,signs and blood gas results in children with bronchitis,reduce the length of oxygen inhalation and stay.HHFNC is an effective and well-tolerated treatment for bronchitis in children.

Objective To investagate the change of creatine kinase MB isoenzymes ( CK-MB ) in children with rotavirus diarrhea and to explore the value of CK-MB/CK in the diagnosis of myocardial damage. Methods A retrospective analysis of the clinical manifestation, laboratory test data and treatment was per-formed in children with rotavirus diarrhea and high CK-MB hospitalized in department of infectious disease, Si-hong Children Hospital. We investigated the dynamic changes of CK-MB in the rotavirus diarrhea patients with and without myocardial damage. Within the non-myocardial damage group, the fluctuation of CK-MB was compared between patients with nutrition therapy and patients with conventional therapy. Receiver operating characteristic ( ROC) curve was used to explore the predictive value of CK-MB/CK for the myocardial dam-age. Results A total of 603 patients (369 males, 234 females, aged 2~48 months) with high CK-MB were enrolled in this study ( 36 cases with myocardial damage ) . There were 54. 6% of enrolled patients showing higher CK-MB and 3. 3% of patients had myocardial damage. The levels of serum CK-MB in non-myocardial damage group reached the peak on day 7 and decreased to normal in 14 days. The levels of serum CK-MB in myocardial damage group reached the peak on day 14 and maintained at fairly high level for 8 weeks and then decreased to normal . Time for CK-MB to achieve peak is different between these two groups. There was no statistical significance in the levels of serum CK-MB on day1 to day 14 between patients with or without myocar-dial protection ( P >0. 05 ) . The ROC curves were constructed with area under the ROC curves of 0. 697 (0. 611, 0. 784, 95%CI). Conclusion Intrinsic dynamics of CK-MB existed in patients with rotavirus diar-rhea. The diagnostic value of CK-MB is limited in patients with myocardial damage.

Objective To detect the expression pattern of microRNA in A549 cells treated by lipopolysaccharide, study the expression of miRNA-1247-3P in A549 cells under LPS treatment and explore the possible mechanism of miRNA-1247-3P in A549 cells under LPS treatment. Methods A549 cells were divided into experimental and control groups. Immunocytochemical method and RT-PCR were used to detect the changes of SP-A and SP-C. The expression of miRNAs were detected using miRNAs array in different groups. The key miR-1247-3P was collected to detect the changes of miR-1247-3P in all groups using quantitative real-time polymerase chain reaction. Results Compared with control group, the expressions of SP-A and SP-C were significantly decreased in the experimental groups (P < 0.05). MiRNA array showed that 31 miRNAs were up-regulated and 3 miRNAs were down-regulated. Compared with control group, the expression of miR-1247-3P was significantly increased in the experimental groups (P < 0.05). Conclusion The increased expression of miR-1247-3P may play an important role in the pathogenesis of ARDS.

Objective To explore the preventive and therapeutic role of silencing type Ⅰ rat platelet-binding protein motifs depolymerization protein-like metalloproteinase 2(ADAMTS2)by siRNA on experimental liver fibrosis in vitro.By studying the mechanism of siRNA silencing of ADAMTS2,we also aim to evaluate the feasibility of ADAMTS2 as a target for anti-liver fibrosis therapy.Methods Three pairs of siRNAs targeting ADAMTS2 mRNA 2237,2597 and 690 targets were designed and synthesized by utilizing RNA design software.The most effective siRNA was chosen to transfect HSC-T6 cell line to test the tendency of hepatic stellate cell(HSC)activation and ex pression of ADAMTS2,COL1α1,COL(I),α-SMA,TGF-β1,MMP-2 and TIMP-3.These were quantified using real time-PCR,Western blotting,and MTT assays.Results Of the same dosage and time of injection,siRNA 2237 inhibited ADAMTS2 gene expression significantly more than other siRNAs.siRNA-ADAMTS2 2237 markedly inhibited ADAMTS2 gene and protein expression of HSCT6 with more than 80％ efficiency.Conversely,siRNA-ADAMTS2 2237 markedly reduced the gene and protein expressions of COL(I),α-SMA and TGF-β1 on HSC-T6 and inhibited the proliferation of HSC.Conclusions siRNA-ADAMTS2 2237 could effectively knockdown the gene and protein expression of ADAMTS2 in HSC-T6 cell lines.Silencing ADAMTS2 by siRNA significantly inhibited the activation,proliferation of HSC and the gene and protein expressions of COL(I),α SMA,and TGF-β1,and it may have a potential anti-fibrotic effect.ADAMTS2 might be an efficient target for anti-fibrotic therapy.
