1.Research on status and application prospects of sonodynamic therapy with intermediate frequency low-intensity ultrasound used to treat endometrial disease
China Medical Equipment 2015;(11):75-77
Sonodynamic therapy in many treatment methods of tumors, is a relatively new approach. Sonodynamic therapy as a treatment method is developed on the basis of photodynamic therapy. Compared to the lightwave, the ability to penetrate mammalian tissue of ultrasound is stronger. So sonodynamic therapy is a more promising therapeutic area. Many scholars have explored the clinical applications of sonodynamic therapy, and progress has been made in many areas. Because the female genitalia is connected the outside of body, it is more conducive that Sonodynamic therapy play a partial role. Sonodynamic therapy has some progress in the application of gynecology, and we hope it would have more progress in the treatment of endometrial disease.

Medical Journal of Chinese People's Liberation Army 2001;0(11):-
Objective To clone the human gene of Hepatitis B virus e antigen binding protein 1 (HBEBP1), which was screened with yeast two-hybrid system and bioinformatics techniques, to construct prokaryotic expression vector of pET-32a(+)-HBEBP1, and to induce the expression of recombinant protein in E. coli BL21. Methods The DNA fragment of HBEBP1 of about 372bp was amplified by reverse transcription PCR (RT-PCR), in which the mRNA was taken from HepG2 cells as the template, and cloned into pGEM-T vector. After restriction enzyme digestion identification and sequencing, the correct target DNA fragment was inserted into inducible prokaryotic expression vector pET-32a(+) and then transformed into competent E. coli BL21. By restriction enzyme digestion and PCR, the positive transformed clones were identified and induced with IPTG to obtain fusion protein. The HBEBP1 fusion protein was analyzed by Western blotting hybridization. Results The 372bp DNA fragment of HBEBP1 was amplified by RT-PCR. The recombinant expression vector pET-32a(+)-HBEBP1 was constructed successfully. After transformation with pET-32a(+)-HBEBP1 and induction with IPTG, the recombinant target protein of about 33kD was obtained, which was consistent with our anticipation. Western blotting assay showed that the protein had good specificity. Conclusions The recombinant prokaryotic expression vector pET-32a(+)-HBEBP1 is constructed, and the HBEBP1 gene is cloned successfully. The HBEBP1 fusion protein could be expressed in prokaryotic expression system of E. coli. These results lays a foundative for studying the immunogenicity and the biological characteristics of the HBEBP1 protein.

Objective To investigate the effect of EGB on SOD, MDA of ventilator-induced lung injury in rats and its possible mechanisms. Methods Thirty male SD rats were randomly divided into 3 groups: control group (C group), high tidal ventilation group (H group) and EGB group (E group). The setting mechanical ventilation was VT=30 mL/kg, RR=40/min, I/E=1/3, PEEP=0 cmH2 O and FiO2=21%. The broncho-alveolar lavage fluid (BLAF) and serum were obtained for determination of the levels of SOD and MDA at the end of 4 h mechanical ventilation. The Lungs were removed, and the wet-to-dry weight ratio (W/D) and pulmonary pathologic changes were measured. Results As compared with C group, W/D and the levels of MDA were significantly increased in H group, but the levels of SOD were reduced in H group. As compared with H group, W/D and the levels of MDA were significantly decreased in E group, but the levels of SOD were increased in E group. Pulmonary pathologic changes were alleviated in E group comparing with H group. Conclusion EGB injection may have a protective role against hyperoxia and induced pulmonary damage in rats.

Chinese Journal of Medical Imaging Technology 2010;26(2):297-300
Objective To explore the diagnostic value of diffusion weighted imaging (DWI) and CT perfusion imaging (CTPI) in diagnosis of liver fibrosis. Methods Fifty-seven hepatic fibrosis patients and 23 normal controls received DWI (b=500 s/mm2), ADC value of different fibrosis stages was measured, while 35 patients and all 23 normal controls received CTPI. The parameters of CTPI including blood flow (BF), blood volume (BV), mean transit time (MTT), hepatic arterial fraction (HAF) and permeability surface (PS) were measured. Analysis of variances was performed to compare the difference among the groups in both examinations. ROC curve was used to analyze the sensitivity and specificity of DWI and CTPI. Results The difference of ADC value between control group and S1 group was not significant, but between control group and S2, S3, S4 group and among group S2, group S3, group S4 was significant. In the parameters of CTPI, only the difference of HAF between control group and S3-S4 group was significant. Sensitivity and specificity of DWI and CTPI was 78.90%, 82.60% and 66.67%, 73.91%, respectively. Conclusion DWI is superior to CTPI for early diagnosis and degrading of liver fibrosis.
