For further research of the apoptosis mechanism of Schistosoma japonicum (S. japonicum). The cDNA encoding Sjcaspase3 of Schistosoma japonicum was amplified by polymerase chain reaction (PCR) technique, which contained 900 nucleotides and encoded 299 amino acids. The theory molecular weight and isoelectric point (PI) of the deduced protein is 33.5 kDa and 6.39, respectively. Real-time PCR was used to analyze the transcription profiles of Sjcaspase3 at different development stages of S. japonicum. The results showed that this gene was expressed in all stages of S. japonicum with the highest expression in 21d worms, and the level of gene transcription in 42 d female worms was higher than that of male worms. The recombinant plasmid pXJ40-FLAG-Sjcaspase3 was constructed and transfection into Hela cells successfully. Real-time PCR and Western blotting analysis showed Sjcaspase3 was successfully expressed in Hela cells. Enzyme activity analysis revealed that recombinant Sjcaspase3 possessed the activity to cut substrate DEVD. Flow cytometry proved that Sjcaspase3 could induce early apoptosis of Hela cells. The results provide the basis for proceeding further study on the biological function of Sjcaspase3 and better understand the apoptosis mechanism of S. japonicum.

BACKGROUND:Different methods of internal fixation can be selected during the repair of femoral shaft fractures in the clinic, including bridging combined internal fixation and metal locking plate screw fixation.
OBJECTIVE: To compare the biomechanical properties of bridging combined internal fixation and metal locking plate screw fixation for femoral shaft fracture.
METHODS:Eighteen femoral samples were colected and randomly divided to three groups, with six in each group. In the normal control group, no treatment was given. In the other groups, models of femoral shaft fracture were established. In the bridging combination group, samples underwent bridging combined internal fixation. In the locking plate screw group, samples underwent metal locking plate screw fixation. Biomechanical test was conducted in samples of the three groups. In the femoral compression experiments, we recorded the maximum displacement under the maximal load 500 N. In the femoral flexion experiment, we recorded the maximum displacement under the maximal load of 100 N. In the femoral retroversion experiment, we recorded the maximum displacement under the maximal load of 100 N.
RESULTS AND CONCLUSION: (1) Compression experiment at different loads: the maximum displacement was larger in the bridging combination group and locking plate screw group than in the normal control group. Under the maximum load of 500 N, the maximum displacement was significantly larger in the bridging combination group and locking plate screw group than in the normal control group (P < 0.05). Moreover, the maximum displacement was significantly less in the bridging combination group than in the locking plate screw group (P< 0.05). (2) Flexion experiment under different loads: the maximum displacement was larger in the bridging combination group and locking plate screw group than in the normal control group. Under the maximal load of 100 N, the maximum displacement was significantly larger in the bridging combination group and locking plate screw group than in the normal control group (P< 0.05). Moreover, the maximum displacement was significantly smaler in the bridging combination group than in the locking plate screw group (P < 0.05). (3) Retroflexion experiment under different loads: the maximum displacement was larger in the bridging combination group and locking plate screw group than in the normal control group. Under the maximal load of 100 N, the maximum displacement was significantly larger in the bridging combination group and locking plate screw group than in the normal control group (P < 0.05). Moreover, the maximum displacement was significantly smaler in the bridging combination group than in the locking plate screw group (P < 0.05). (4) These results suggested thatin vitro simulated femoral shaft fracture bridging combination fixation and metal locking plate screw system can obtain good fixation effect; the design meets the principle of biomechanics. Among them, bridging combined internal fixation can maintain a smaler displacement, suggesting good deformation resistance under compressive stress, anteflexion and retroflexion stress.

Objective To investigate the clinical application of nasal-insertion type ileus-tube in the treatment of adhesive small intestinal obstruction. Methods A total of 221 patients with simple adhesive small intestinal obstruction, who were admitted to authors’ hospital during the period from January 2010 to Aug. 2014, were enrolled in this study. The patients were randomly divided into nasal-insertion type ileus-tube group (n=111) and nasogastric tube group (n=110). After the procedure, the patients were kept under close observation, focusing on the abdominal distention, gastrointestinal decompression amount, the recovery time of anal exhaustion and defecation, the vanishing time of intestinal air-liquid plane on erect abdominal X-ray film, etc. The cure rate, effective rate and transit-operation rate were calculated. The results were compared between the two groups. Results The tube placement operation was successfully performed in all patients. Compared with the nasogastric tube group, in the nasal-insertion type ileus-tube group the recovery time of abdominal distention, anal exhaustion and defecation and the vanishing time of intestinal air-liquid plane on erect abdominal X-ray film were obviously shorter, and the gastrointestinal decompression amount was larger. In the nasal-insertion type ileus-tube group the cure rate and effective rate were significantly increased, while the transit-operation rate was decreased; the differences between the two groups were statistically significant (P<0.05). Conclusion For the treatment of adhesive small intestinal obstruction, the placement of nasal-insertion type ileus-tube is effective and reliable. This technique can strikingly improve the clinical symptoms, therefore, it is worthy of promotion and application in clinical practice.

Objective:To observe and study the short-term efficacy of levocarnitine combined with trimetazidine in the treatment of elderly heart failure of ischemic cardiomyopathy. Methods:Totally 106 elderly patients with ischemic cardiomyopathy and heart failure were randomly divided into the observation group and the control group with 53 ones in each. All the patients were given anti-platelet, anti-myocardial ischemia and lipid-lowering therapy as well as the conventional therapy on myocardial ischemia. The control group was treated with trimetazidine,20mg,po,tid,while the observation group was additionally treated with 2g levocarnitine with 0. 9% sodium chloride injections,100ml,ivd,qd. The treatment course was 4 weeks. The improvement of heart function and the changes in cardiac function indices( including LVEDD,LVESD and LVEF)and cardiac ischemia markers( CKMB,TüI and BüP)before and after the treatment were compared between the two groups. The incidence of adverse drug reactions,the rate of re-hospitalization and mortality in the two groups were also compared. Results:The significant efficiency and total effective rate in the observation group were much higher than those in the control group(P<0. 05 or 0. 000 1). After the treatment,LVEDD and LVESD in the two groups were declined, LVEF was increased(P<0. 05),and the changes in the observation group were more notable than those in the control group(P<0. 05 or 0. 000 1). After the treatment,the contents of CKMB,TüI and BüP in the two groups were lower than those before the treat-ment(P<0. 05),and the decrease in the observation group was more notable than that in the control group(P<0. 05). There were no significant differences in the incidence of adverse reactions,re-admission rate and mortality between the two groups(P>0. 05). Conclusion:Levocarnitine combined with trimetazidine on the basis of the conditional therapy in the treatment of elderly patients with ischemic cardiomyopathy and heart failure can effectively improve heart function with better clinical efficacy,which is worthy of promo-tion in clinic.

This surgery performed in Ponseti approach will always achieve a successful result.

To evaluate the immunities of biodegradable microsphere as a release delivery system for DNA vaccine against Infectious Bursal Disease Virus, in our study, silk fibroin/chitosan microsphere adjuvant was prepared with a precipitation/coacervation method. Both glutaraldehyde and Na2SO4 solution were used in cross-linking. No immune chicken were intramuscularly inoculated at 14 day-old and boosted 2 weeks later. The results show that glutaraldehyde destroyed the DNA activity of the vaccine whereas Na2SO4 solution did not. Factors of the chitosan concentration 0.5% (pH 5.0), silk fibroin concentration 0.6%, plasmid DNA (500 microg/mL) dissolved in 2% Na2SO4 solution were optimized to produce microsphere, with a loading capacity of 89.14%. The average particle size of SF-CS/pCI-VP2/4/3 microsphere is 1.98 microm, and it can protect the loading DNA vaccine from DNase I digestion. Data from anti IBDV ELISA antibodies in the serum show that immunization activity of the microsphere groups were generally higher than plasmid vaccine group (P < 0.05), and the SF/CS compound microspheres group was better than that of sole CS microsphere group. The developed SF/CS microspheres are a very promising vaccine delivery system.
