Objective To investigate the effect of puerarin and compound salvia injection on P2selectin change in patients with traumatic cerebral infarction(TCI)so as to understand the difference of their curative effect. Methods Twenty patients with TCI were randomly divided into four groups,ie,conventional treatment group,puerarin group,compound salvia injection group and combined treatment group to observe the improvement of the symptoms(Glasgow Outcome Scale,GOS)and change of plasma P2 selecfin after treatment.Results The symptoms(GOS score)and level of plasma P2 selectin in the puerarin group,the compound salvia injection group and the combined treatment group were superior to those of the conventional treatment group(P<0.05).The TCI patients had obviously higher level of plasma P2 Selectin than the healthy persons before treatment.The level of plasma P2 selectin was decreased after treatment,with better curative effect in three other groups compared with the conventional treatment group. Conclusions There is positive synergistic interaction between puerarin and compound salvia injection.Both puerarin and compound salvia injection Can decrease the level of plasma P2 Selectin to reduce the blood viscosity,inhibit the platelet activation,reduce the cerebral vasospasm and inhibit the thrombosis,as contributes to the recovery of the TCI patients.

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.

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.

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 investigate the relationship between the severity of infant/toddlers wheezing and hand,foot and mouth disease (HFMD) infection.Methods We selected infant/toddlers wheezing with HFMD cases in respiratory department of our hospital from January 2010 to January 2012,and 30 cases of enterovirus 71 (EV71) were selected as the experimental group and 30 cases of coxsackie virus A type 16 (CA16)as the control group,respectively,according to HFMD pathogen infection.Wheezing cases by severity were divided into intermittent stares with mild persistent group (A) and moderate and severe persistent group (B).HFMD by severity were divided into ordinary and severe cases group.Wheezing severity before and after HFMD,relationship between HFMD severity and wheezing severity and the content of serum cytokines such as interferon-γ(IFN-γ) and interleukin-4 (IL-4) were compared between EV71 group and CA16 group,and statistical analysis was performed.Results (1) Wheezing severity(A,B) corresponding cases:EV71 group(25,5),(5,25),and CA16 group(24,6),(15,15) before and after HFMD.The case-constituent ratio in EV71 and CA16 same group was compared before and after infection,and the differences were statistically significant(P ＜ 0.05).The differences in EV71 group and CA16 group were not statistically significant (x2 =0.11,P ＞ 0.05)before infection,and were statistically significant(x2 =7.50,P ＜0.05) after infection.(2) Severe cases,ordinary group and severe wheezing (A,B) corresponding cases:(17,1),(32,10) before infection,and (2,16),(18,24) after infection.The upgrade cases constituent ratio of wheezing severity after infection were compared between severe and ordinary cases group,and the difference was statistically significant (x2 =5.88,P ＜ 0.05).(3) The content of serum cytokines as IFN-γand IL-4 and IFN-γ/IL-4 ratio were compared in EV7l group and CA16 group before and after infection,and the differences were statistically significant (P ＜ 0.001) ; and the differences compared in EV71 group and CA16 group were not statistically significant(P ＞0.05) before infection and statistically significant(P ＜ 0.05) after infection.Conclusions Infant/toddlers wheezing with HFMD and wheezing severity of severe disease and EV7l infections were exacerbated trend in the short term after infection.The infection of EV71 may promote Th1/Th2 drift.

Obstructive sleep apnea (OSA) is characterized by repeated intermittent hypoxia (IH), hypercapnia, sleep fragmentation and intrathoracic pressure change. IH is related to the clinical pathophysiological processes of hypertension, atherosclerosis, coronary heart disease, arrhythmia, stroke, heart failure and sudden death. IH from OSA can lead to metabol-ic dysregulation, endothelial dysfunction, systemic inflammation, oxidative stress and the change of nerve body fluids, which has been shown to increase the risk of cardiovascular diseases. This study mainly describes the pathogenesis of IH leading to the various cardiovascular diseases.

OBJECTIVE:To study the stability of omeprazole sodium solution for injection under the influence of metal ion calcium and magnesium.METHODS:HPLC was adopted to determine the variation of the content of omeprazole sodium solution acted by metal ion calcium and magnesium of different concentrations in different time.The change in colour and luster was also observed.RESULTS:Omeprazole sodium solution tended to disintegrate rapidly along with the prolonging of time,and increase with the increasing of concentration;when Mg2+ was added,change in color was seen,with no degradation substance produced;when Ca2+was added,change in color was also seen,with white deposit produced.CONCLUSION:Ca2+ and Mg2+ show significant influence on the stability of omeprazole sodium solution.

Tetrabromobisphenol A(TBBPA)is supposed to have potential thyroid disrupting activities due to its similar structure to thyroid hormones.TBBPA has been proved to show thyroid disrupting effects in vivo and in vitro studies.TBBPA might disrupt thyroid hormone system through transthyretin- and thyroid receptor-mediated pathways.The ability of TBBPA inducing the production of reactive oxygen species might be the extension of its thyroid disrupting activities.The thyroid disrupting effects of TBBPA might be closely related to its oxidative stress,reproduction toxicity and neurotoxicity.More experiments are required for the effects of TBBPA on the aquatic and amphibian animals.
