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.

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.

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 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.

BACKGROUND:Healthy human umbilical cord jel y is a mucous connective tissue without vessels and has been used in eye plastic operation because of its elasticity and toughness. It contains lysozyme, placental globulin, hyaluronic acid enzyme, AMP antibody and complement, and also contains a lot of mesenchymal stem cells, so it is not prone to infection and rejection. OBJECTIVE:To observe the histocompatibility and histopathological changes of human umbilical cord jel y as a tarsal substitute transplanted for eyelid reconstruction in guinea pigs. METHODS:The mucous connective tissue of healthy neonate umbilical cord jel y was made into tissue blocks at even thickness. Models of tarsal defects were established in guinea pigs, and then the mucous connective tissue of healthy neonate umbilical cord jel y was implanted. Samples of implanted materials were col ected for histological examination at 1, 2, 3 weeks postoperation under light microscope. RESULTS AND CONCLUSION:There were no obvious rejection, infection and eyelid deformation observed, the corneas of al the animals were clear, corneal epithelial shedding did not occur, and the eyelid could move normal y. One week after implantation, there was no infection and rejection on the conjunctiva and the incision of the eyelid, the eyelid could move normal y, and partial inflammatory cells were observed between the human umbilical cord jel y and the muscle of the eyelid with microscopy. Two weeks after implantation, there was no infection and rejection on the conjunctiva and the incision of the eyelid, the cornea was clear, the eyelid and eye could move normal y, and no symblepharon occurred;umbilical cord jel y showed the tendency of absorption, and the inflammatory cells were reduced at 2 weeks after implantation. Three weeks after implantation, the incision of the conjunctiva healed wel , the cornea was clear;there was no difference in the eyelid form and movement between the two eyes;the umbilical cord jel y was absorbed partial y, normal fibrous tissues formed and there were no inflammatory cells. With low immunogenicity, human umbilical cord jel y can guide the growth of new col agen and serve as an ideal tarsal substitute.

Objective To investigate the clinical efficacy of Pingchuan cataplasm combined with hyperthermia therapy for stable chronic obstructive pulmonary disease (COPD) with qi deficiency syndrome of both lung and spleen. Methods Sixty patients of stable COPD with TCM syndrome of qi deficiency of both lung and spleen were selected and randomized into treatment group and control group, 30 cases in each group. Based on conventional treatment, the treatment group was treated by Pingchuan cataplasm combined with hyperthermia, and the control group was given analog stick applicator without additional heat treatment. After 6 weeks of treatment, the TCM symptom score and the time of the first exacerbation after treatment were observed. Results Compared with the control group, Pingchuan cataplasm can reduce the patients’ TCM symptom score (F=9.843, P=0.003), and extend the interval of acute exacerbation after treatment (F=4.451, P=0.040). Conclusion Pingchuan cataplasm combined with hyperthermia applicator can improve symptoms and reduce the frequency of acute exacerbation, thus can treat and prevent the acute exacerbation of COPD.
