ObjectiveTo investigate the effects of X-linked inhibitor of apoptosis (XIAP) siRNA or XIAP antagonist Embelin on the growth inhibition and apoptosis of hepatcellular cancer cell line HepG2,which was treated by tumor necrosis factor-related apoptosis (TRAIL). Methods HepG2 cells were tranfected either by XIAP siRNA or a negative control,followed by treatment with TRAIL,Embelin or a combination of the two.XIAP expression,cell growth,and caspase-3 activity were determined by Western blot,MTT assay and fluorescent caspase-3 assay,respectively.Cleaved PARP expression levels of were measured by Western blot.ResultsThe XIAP protein expression was significantly downregulated by transfection with XIAP siRNA.Compared with the negative control,the XIAP siRNA significantly inhibited the growth of HepG2 cells treated by 100ng/ml(6.8％ ±1.2％ vs.11.8％±4.0％,P＜0.05)and 1000 ng/ml (18.9％ ±2.0％ vs.26.6％ ±1.5％,P＜0.01)by TRAIL.TRAIL-induced caspase-3 activation and PARP cleavage were also increased significantly by XIAP siRNA transfection.In addition,Embelin also significantly inhibited cell growth (P＜0.01),activation of caspase-3 (P＜ 0.01) and TRAIL-induced PARP cleavage.Conclusions Both XIAP siRNA and Embelin may potentially contribute to clinical treatment of hepatocellular carcinoma.

Objective: To investigate the effect of leech injection on thrombosis and plasma tissue plasminogen activator (t PA) and its inhibitor (PAI) in the thrombosis model of mice. Methods: The different dose leech injection of different doses were given to mice in different groups for 7 days respectively. Thrombosis was induced in mice by carrageenan. The plasma t PA and PAI activity were detected by chromogennic substracte analysis.Results: The average thrombosis length of tail in the groups of leech injection were significantly shorter than the length in the groups of thrombosis control. Compared with the group of thrombosis control, the plasma PAI activity in the leech injection groups was lower. Conclusions: The leech injection can reduce thrombosis in mice. The mechanism might be associated with reducing the release of PAI.

OBJECTIVE:To observe therapeutic efficacy and safety of carboprost tromethamine in the treatment of postpartum hemorrhage with two routes of administration. METHODS:285 patients with postpartum hemorrhage were randomly divided into control group(143 cases)and trial group(142 cases). Control group was given Carboprost tromethamine injection 250 μg on del-toid of arm;trial group was given same dose of Carboprost tromethamine injection via cervix uteri. Both groups received medicine after third stage of labor. The therapuetic efficacy,the amount of endometrorrhagia and colporrhagia within 2 h,the incidence of ADR after labor were observed in 2 groups. RESULTS:After treatment,the amount of postpartum hemorrhage was smaller than 400 ml in 2 groups and didn't exceed the standard,without statistical significance(P>0.05). The amount of endometrorrhagia in trial group was significantly higher than in control group,with statistical significance(P<0.05);the amount of colporrhagia in tri-al group was significantly lower than in control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between trial group(4.90%)and control group(6.31%)(P>0.05). CONCLUSIONS:The intramuscular injection is selected for the prevention of postpartum hemorrhage caused by uterine inertia;the cervical injection is selected for the prevention of postpartum hemorrhage caused for the other patients.

Objective To evaluate the usefulness of the transect imaging and 3D-reconstruction with spiral CT in acetabulum fracture.Methods 23 cases of acetabulum fracture proved by clinical plain radiograph,transect imaging and 3D-reconsection were reviewed retrospectively.3D-reconsection were obtained on the basis of spiral transect imaging with use of 2~3 mm collimation.3 pitch and 1.2~2 mm reconstruction interval.Results Fractures were demonstrated definitely with transect imaging.3D-reconstruction in all patients the transect imaging displayed the fractures and the displacement of the burden opex of acetablulum,the disruption within joint,the direction of fracture.Displacement of detached bone fragments and capitis femoris were display stereoscopically by 3D-reconstruction.Conclusion The transect imaging and the 3D-reconstruction of spiral CT technique with spiral CT could afford the more valuable messages.Surgeon will benefit greathy from their usefulness in the choice of the surgical intervention and operative planning.

Objective To evaluate the clinical value of bronchofiberscope and catheter intervention in treatment of multi-drug resistant pulmonary tuberculosis.Methods Thirty-five patients with multi-drug resistant pulmonary tuberculosis were treated by injecting drug gel,it was composed by rimifon and rifampin and aldinamide and capreomycin through bronchofiberscope and catheter in addition to chemotherapy,while thirty-five controls were treated by chemotherapy only.Results At the end of the treatment,the sputum bacterial conversion to negative rate was 88 5%,radiographic improvement rate was 82 9% and cavity closing rate was 31 4% in the treatment group,all of which were higher than in the controls(51 4%,45 7% and 11 4% respectively)(P

Objective:To study the possible therapeutic mechanisms of triptergium wilfordi in treating glomerulonephritis.Methods:Thirty seven patients with IgA nephropathy were detected urine mononeuclear cells densities with flow cytometry during taking triptergium wilfordi tablets,30 healthy people were used as normal control.Results:The patients urine CD3 +?CD4 +?CD8 +?CD14 + and CD44 + cells densities were much higher than normal control's,but obviously decreased after triptergium wilfordi treatment.CD4/CD8 ratio was much lower in patients than in normal control.It increased markedly after treatment.Patients who reached remission initially had a lower CD4 + cell percentage and higher CD14 + cells percentage than those showed no response to triptergium wilfordi treatment.Conclusion:Triptergium wilfordi could modulate kidney immune cell function and adhesive molecule CD44 expression.Its effects were associated with renal immunity.

Diminished apoptosis,due to overexpression of antiapoptotic proteins, is involved in tumorigenesis and chemoresistance. Antisense oligodeoxynucleotide (ASODN) has been used to inhibit the expression of antiapoptotic proteins(f.g bcl 2, bcl x L , survivin),aimed to induce apoptosis or enhance chemosensitivity.The combination of ASODN with conventional treatment is possibly a reasonable approach in furture cancer therapy.

OBJECTIVE To investigate the drug resistance of Escherichia coli in biliary tract infection and genotype of ESBLs.METHODS Antimicrobial susceptibility test was performed using Kirby-Bauer method.The genotypes of ESBLs were detected by PCR.RESULTS The detection rate of ESBLs producing bacteria was 32.4%(23 strains),and the drug-sensitivity test indicated that E.coli was sensitive to imipenem,meropenem and cefoperazone/subactam,but these ESBLs producing strains were resistant to other antimicrobial agents.ESBLs were identified as TEM type in 16 strains,SHV type in 4 strains,CTX-M type in 12 strains and OXA type in 5 strains.CONCLUSIONS ESBLs-producing E.coli in biliary tract infections show strous resistance.TEM and CTX-M are the most common ESBLs genotypes.

Objective The purpose of this study was to edit and psychometrically equate a set of Mandarin bisyllabic word lists. Methods 964 bisyllabjc words were recorded by male talker of standard Mandarin,352 words were selected to compose 10 lists. Percentage of correct word recognition was measured for each word at four intensity levels using 20 normal hearing subjects. The order of the presentation of the lists was randomized for each subject. U-sing Statistica7.0 Performance-Intensity function for each word was plotted,slopes and thresholds of them were calculated. 242 words were chosen after that, The thresholds and slopes of these words were in Guassian distribution. These words were ligitally adjusted and included in six Mandarin bisyllabic word lists of 40 words each. Two of them were for practice, four of them for test. 36 subjects with normal hearing served in our equivalent test. The orders of the presentation of the lists were randomized far each subject and results were expressed as thresholds. Results Two-factor ANO-VA was used to compare the thresholds of the 4 lists, F=1.978,P = 0.209. Conclusion These lists were considered to be primarily equivalent with each other.

Objective To summarize the characteristics of ecthyma gangrenosum and explore its significance in early diagnosis of pseudomonas aeruginosa sepsis in children.Methods We retrospectively reviewed the medical records of 11 children with ecthyma gangrenosum who were hospitalized at Guangzhou women and children's medical center between May 2008 and Apr 2011.Results Eight cases were male and 7 were less than twelve months,the oldest was 2 years old,all of them were diagnosed as Pseudomonas aeruginosa spesis.Two patients had a single lesion,and the others had multiple lesions.Ecthyma gangrenosum located on the trunks in 7 cases,on anogenital areas in 5 cases,on extremities in 5 cases and on faces in 3.The lesions appeared on day 2 to day 10.On average,they developed on day 5.Seven patients developed ecthyma gangrenosum before admission,the course of the illness before admission was 6 days.Fever and multiple organ dysfunction occurred in all the patients and their cultures grew pseudomonas aeruginosa,blood cultures were positive in 8 cases,the others were isolated psudomonas aeruginosa from tissue of the lesion,discharge,ascites,pleural effusion,respectively.The time of ecthyma gangrenosum appeared was earlier than the time of the culture results reported.All of the patients were started empiric antibiotics therapy on admission,the initial antibiotic regimen was appropriate in 9 patients,8 needed surgical intervention,4 were treated with continuous blood purification.Ten patients survived and 2 died,the hospital stay was from 1 to 63 days,the average was 30.Conclusion Ecthyma gangrenosum is a known cutaneous manifestation of pseudomonas aeruginosa sepsis,which is helpful for early diagnosis and treatment,and then the outcome will be improved.
