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.

P-selectin, pro thrombin fragments 1+2 (F1+2), D-dimers(D-D) and plasmin-antiplasmin complex (PAP) were measured by enzyme linked immunosorbent assay. Antithrombin activity (AT: A) was measured by chromogenic peptide substrate assay. 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 expression of human kallikrein gene(KLK) 4 and KLK5 in ovarian cancers,and to investigate the pathogenesis in malignant tumors. Methods Fifty specimens of ovarian cancers were divided into three groups: malignant tumor group(n=23),borderline tumor group(n=6) and control group(normal or benign tumor,n=21).Fluorescent quantitative RT-PCR was employed to determine the expression of KLK4 and KLK5 in these specimens. Results The expression of KLK4 in ovarian cancers was significantly higher than that of the control group(P

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 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 The experimental evidences that long term colonization of H. pylori results in development of gastric cancer in Mongolian gerbils (MGs) have been reported only by two Japanese groups so far. This study aimed to investigate the carcinogenicity of long term H. pylori infection in MGs model. Methods Thirty six 6 week old outbred MGs (from Inner Mongolia, male∶female=1∶1) were orally inoculated with H.pylori ATCC43504 or H.pylori 161, which was isolated from a patient with gastric adenocarcinoma in our hospital. Another 10 MGs were inoculated with sterilized PBS served as controls. The animals were sacrificed 8, 20, 28 and 84 weeks, respectively, after inoculation for bacteria and histological examination. Results H.pylori was detected in 80%(23/29)of the inoculated MGs and the chronic active gastritis aggravated gradually during the course of experiment. At the 84th week, moderate to severe gastritis, characterized by diffuse infiltration of mononuclear cells and formation of multiple lymphoid follicles in the mucosa and submucosa, and even the lymphocytic epithelial lesions were observed. Atrophy and intestinal metaplasia were less common. The lesions of hyperplasia were dominating in almost all MGs, 24%(4/17)of the animals occurred hyperplastic polyps. Well differentiated gastric adenocarcinomas were developed in 18% (3/17) of the MGs by the end of the 84th week (1 infected with H.pylori 161 and 2 with H.pylori ATCC43504, two of them were female MGs). Conclusions The results reconfirm that H.pylori infection alone can cause gastric adenocarcinoma in MGs. It is suggested that different species of MGs and various strains of H.pylori can be utilized for carcinogenesis research. It is the first report of the development of gastric cancer in female MGs, which might make sense of investigation on the host susceptibility influenced by gender.

Objective To evaluate the preventative effects of rehabilitation training(RT)on deep venous thrombosis(DVT)after arthroplasty.Methods Fifty-six patients with articulatio coxae or knee arthroplasty were randomly divided into a control group and an experiment group(E group).RT,including active movement of the foot and ankle,isometric contraction of the quadriceps fexoris and deep breathing training,was administered to the E group after arthroplasty.Negative cheirapsis was applied in the control group.Peak and average blood flow velocities (PABFVs)in the femoral vein,as well as DVT,were detected and measured using color ultrasound Doppler imaging before and 7 d after arthroplasty.Results PABFVs in the E group were higher than those in the control group (P

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.
