Objective To assess the effects of intraventricular conduction abnormality on left ventricular function in dilated cardiomyopathy. Methods The study composed of 3 groups,16 patients of dilated cardiomyopathy (DCM) without wide QRS complexes, 16 patients of DCM with complete left bundle branch block(CLBBB),and 16 age-matched healthy individuals,all showing sinus rhythm and being complicated with mitral regurgitation. Pre-ejection contraction time(PET), left ventricular ejection time(LVET), left ventricular filling time(LVFT), myocardial performance index(MPI), mitral regurgitation time(MRT), stroke volume(SV) were recorded with pulsed or continuous-wave Doppler. Pulse tissue Doppler imagining(TDI) was performed to measure the time dispersity of electromechanical motion of left ventricular in systole and diastole on the atrial-ventricular annulus with mapping techniques. Results Time dispersity of electromechanical motion of adjacent left ventricular segments in systole[((77.9)?(13.6))ms vs ((52.1)?(13.2))ms vs ((28.3)?(7.2))ms, P

Objective To evaluate the effectiveness and safety of TCM treatment to children with mycoplasma pneumonia. Methods RCTs of trational Chinese medicine in treating children with mycoplasma pneumonia were retrieved. CNKI, Wanfang Database and CBMdisc were searched for Chinese literature, and PubMed, EMbase and Cochrane Library were searched for foreign literature. All searching time was up to May 25, 2012. Data were picked up by two system reviewers individually and evaluation standard of Cochrane was used to evaluate the quality of selected literature. Results A total of 64 RCTs including 6289 cases of children with mycoplasma pneumonia were analyzed. In the improvement of clinical symptoms, among comparison between traditional Chinese medicine and western medicine (RR=1.10, 95%CI:-1.0--1.18) and comparison between traditional Chinese medicine plus western medicine and western medicine (RR=1.14, 95%CI:1.10-1.18), curative effects of treatment group were superior to the control group, P<0.00;For the fever clearance time, among comparison between traditional Chinese medicine and western medicine (RR=-4.26, 95%CI:-8.15--0.37), comparison between traditional Chinese medicine plus western medicine and western medicine (RR=-0.97, 95%CI:-1.27--0.66), curative effects of treatment group were superior to the western medicine group. For the time of the disappearance of cough and pulmonary rales, and the basic X-ray absorption time, curative effects of treatment group were also superior to the control group. Untoward effects in western medicine group were obvious than that of traditional Chinese medicine group. Conclusion TCM could improve and shorten the duration of symptoms of children with mycoplasma pneumonia. However, it is still necessary to be verified with more multi-center, double-blind, large sample randomized controlled trials, since the literature which have been brought into related researches were with low quality.

OBJECTIVE: To develope a reversed-phase high performance liquid chromatographic(RP-HPLC) method for the determination of allitridum in human serum.METHODS: The serum sample was injected after being deproteinized with trichloroaceticacid and being extracted with hexane.A Phenomenex C1s was used as the stationary phase and the solution being composed of acetonitrile- 1%HAc(62: 38,V/V)as the mobile phase with a flow rate of 1.2 ml/min .The serum samples were monitored at 240nm.RESULTS: The peak area of allitridum against allitridum concentration was linear with a correlation coefficient of 0.9 977 over the range of 0.29～12.4 μg/ml, the limitation of detection was 0.18 μg/ml.The average recovery was (99.2 ± 6.6) %, within - day RSD＜ 5.5% (n = 5), between - day RSD＜ 5.8% (n = 5) .CONCLUSIONS: This method is rapid, accurate and sensitive,it is very suitable for the investigation on clinical pharmacokinetics of allitridum.

[Objective]To explore the value of magnetic resonance imaging (MRI) for articular cartilage lesions after bone bruise of distal femur under arthroscopy.[Method]Articular cartilage lesions of 29 cases of distal femur bruises diagnosed by MRI were examined under arthroscopy,12 cases of them combined with medial and lateral meniscus injury,17 combined with anterior cruiciate ligament rupture.[Result]The distal femur articular cartilage lesions examined under arthroscopy were corresponding to MRI findings.The lesions showed by arthroscopy were in direct proportion to MRI.These lesions were classified into Ⅰ-Ⅳ degrees.[Conclusion]Arthroscopic examination showed correspondent result to MRI findings for articular cartilage lesions.Sometimes MRI couldn't deliver the severity of cartilage lesions because of instrument factors.Arthroscopy is considered as the golden standard of evaluation for articular cartilage lesions after bone bruises.

20?10 9/L on day 16 (range 9~35).Over grade Ⅱ acute GVHD occurred in three patients(25%) and chronic GVHD occurred in five patients, including three patients with localized chronic GVHD and two with extensive chronic GVHD . The incidence of acute GVHD in allo-PBSCT is similar to allo-BMT, while care should be taken for the occurrence of chronic GVHD.

To analyze the outcome of allogeneic peripheral blood stem cell transplantation(allo PBSCT) for hematological malignancies and prevention of complications, forty one patients with hematological malignancies were treated with allo PBSCT. One regimen of prophylaxis for acute graft versus host disease(GVHD) was the combination of cyclosporine(CsA)and methotrexate(MTX),another mycophenolate mofetil(MMF) with cyclosporine and methotrexate .The results showed that all patients were successfully engrafted .The incidence of over grade Ⅱ acute GVHD after HLA matched transplantation was 21 05%(8/38). Chronic GVHD occurred in 19/25(76%) patients. Three of thirty four patients with acute leukemia(CR 1 ) and CML(CP) after HLA matched transplantation relapsed(8 82%). The disease free survival was 71 43%(10/14) after follow up for more than 2 years. The results suggest that the incidence of acute GVHD in allo PBSCT appears to be similar to allo BMT, but the incidence of chronic GVHD in allo PBSCT is higher than that in allo BMT. Infection and interstitial pneumonitis are the main cause of death.

OBJECTIVE: To investigate the characteristics and regularity of adverse drug reactions (ADR) occurred in our hospital. METHODS: 286 ADR cases collected from our hospital from Jan. 2007 to Jun. 2009 were analyzed statistically. RESULTS: There were 3 severe ADR cases. 213 ADR cases were caused by anti-infection agents in our hospital (74.48%), followed by 38 ADR cases caused by TCM preparations (13.29%). Main clinical manifestation of ADR cases were lesion of skin and its appendants in 146 cases (44.92%), followed by 62 cases of lesion of digestive system (19.08%). 202 ADR cases were caused by intravenous administration (70.63%). CONCLUSION: Pharmaceutical monitoring and administration system should be established and improved. Great importance should be attached to ADR monitoring to reduced the incidence of ADR in our hospital.

Objective To investigate the effect of continuous video EEG monitoring on acute cerebral infarction comorbid epileptiform discharges and clinical seizures,and the relationship between cerebral infarction site and seizures.Methods Of the 337 patients continuously video EEG monitored in NICU at our department,259 were included for this study according to our inclusion and exclusion criteria.We recorded patients' epileptiform discharges,type and time of clinical onset,detailed CT and (or) MRI display,cerebral infarction site,and demographic data including admission age,gender,disease history and NIHSS score.Results There were 227/259 (88％) cases showed abnormal discharge in EEG,including 94 with side hemispheric slow wave,99 with local changes,34 with slow wave combined with epileptiform discharges.Early seizures was found in 12 cases,including 3 cases with seizure-induced cerebral infarction,9 cases with attack within one week after cerebral infarction.Ten in the 12 patients had tonic-clonic seizures,and the other 2 cases hadlocal seizures.Epileptiform discharges in EEG was found in 9 cases of the 12 patients.Clinical seizures were not observed in 25 patients with epileptiform discharges in EEG.Results on the relationship between cerebral infarction site and epileptiform discharges showed that incidence of epilepsy in patients with watershed infarction was significantly higher than other types of cerebral infarction (29.0％ vs 13.4％ and 9.0％,P =0.03,0.01 ).Conclusion Continuous video EEG monitoring is capable of detecting early epilepsy and epileptiform discharges.It can provide theoretical basis for the prevention and treatment of epilepsy.

Objective To study the value of CRP and HCY in each TCM type of T2DM with HUA and provide the basis for classification and treatment.Methods 103 cases of T2DM and HUA were divided into four Chinese medicine syndrome groups including deficinecy syndrome of wind-cold and damp-heat phlegm accumlatoin and blood stasis syndrome deficinecy syndrome of Qi and Yin deficinecy syndrome of Yin and yang.Results The differentiation of TCM symptom among four groups was uncorrelated with the level of CRP and Hcy.But the serum CRP and HCY levels increased slighly as compared with those of normal control group.Conclusion The elevation of CRP and Hcy is closely correlated with phlegm accumlation and blood stasis syndrome in patients of T2DM with HUA.As an inflammatoy biomarker,CRP and Hcy may be regard as two of the microcosmic indicators of toxin in Chinese medicine.They can be used as two important indexes of TCM syndrome differentiation of T2DM with HUA.

Objective To investigate the effect of di-2-ethylhexyl phthalate (DEHP) on the proliferation of SK-N-SH human neuroblastoma cells and its underlying mechanism. Methods Cells were cultured in estrogen-free improved Dulbecco's Modified Eagle's Medium and then divided into 5 groups: no treatment (control group); treated with 17β-estradiol (E_2 group); treated with DEHP (DEHP group); treated with both E_2 and phosphatidylinositol-3-kinases (PI3K) inhibitor LY294002 (E_2 + LY294002 group); treated with both DEHP and LY294002 (DEHP + LY294002 group). The absorbance value (AV) was measured on day 0, 2, and 5. DNA proliferation index (PI) and apoptotic index (AI) were determined by flow cytometry on day 5. Caspase-3 protein, protein-serine-threonine kinase (Akt) and phosphor-Akt (Ser473) protein expression were analyzed by Western blot on day 5. Results The AV of All groups increased on day 2, and 5. The AV of E_2 and DEHP groups were higher than that of the control group (P<0. 001), but the AV of E_2 + LY294002 and DEHP + LY294002 groups were lower than those of E_2 and DEHP groups (P<0.01) on day 2 and 5. On day 5, PI of E_2 and DEHP groups were also higher than that of control (P<0.01). However, PI of E_2 + LY294002 and DEHP + LY294002 groups were lower than those of E_2 and DEHP group (P<0.01) on day 5. There was no significant difference in AI and caspase-3 protein expression among the groups. At the same time, phosphor-Akt (Ser473) protein expression of E_2 and DEHP groups increased obviously, compared with the control group. Compared with E_2 and DEHP groups, E_2 + LY294002 and DEHP + LY294002 groups decreased significantly. However, Akt protein expression was equal among those groups. Conclusions DEHP can promote the growth of SK-N-SH cells to a level similar to that of E_2, with activation of the PI3K/Akt signaling pathway.
