3.Analysis of protoscoleces-specific antigens from Echinococcus granulosus with proteomics combined with Western blot.
Biomedical and Environmental Sciences 2012;25(6):718-723
OBJECTIVETo establish and optimize the proteomic analysis of protoscoleces-specific antigens from Echinococcus granulosus. To provide a foundation for identifying specific antigens in the soluble proteins of E. granulosus protoscoleces for further research.
METHODSBrood capsules were collected aseptically from fertile E. granulosus cysts from the livers of an infected patient. The fertile E. granulosus cysts were fractured, and protoscoleces were collected by centrifugation. The soluble proteins of protoscoleces were acquired using the 2D Quant kit according to the manufacturer's instructions. We employed two-dimensional electrophoresis (2-DE) combined with immunoblot assay (Western blot) to analyze the soluble components of E. granulosus protoscoleces antigens. The 2-DE and immunoblot maps obtained were analyzed with PDQuest 8.0 image analysis software.
RESULTSAbout 233 soluble protein spots were identified with Coomassie-stained gels. Most of the proteins had a molecular weight of 16,000 Da to 117,000 Da, and an isoelectric point value of 3.0 to 10.0. 2-DE immunoblot was conducted and 57 specific antigen spots were observed, among which 23 spots were identified.
CONCLUSION2-DE combined with Western blot is the key to successful proteomic analysis and presents a new possibility for searching the specific E. granulosus protoscoleces antigens.

China Journal of Orthopaedics and Traumatology 2015;28(9):820-823
OBJECTIVETo evaluate the clinical effect of a new surgical approaches for repairing the acute Achilles tendon rupture.
METHODSFrom January 2009 to January 2014, 21 patients with Achilles tendon rupture were treated by 2 minimally invasive incisions and remaining skin bridge of achilles tendon end including 16 males and 5 females with an average age of 44.3 years old ranging from 21 to 57 years old. Postoperative complications, the range of movement of affected ankle joint, the circumference calf and ankle on both side, time of reture to work and sports activity were observed and recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate the functional recovery.
RESULTSAll patients were followed up for 6 to 36 months with an average of 13.5 months. No skin necrosis, wound infection, deep vein thrombosis,re-rupture and sensory disturbance with the ankle or foot in the sural nerve distribution were found. At 1 year after operation, there was no significant difference in the range of movement between affected foot (55.4 ± 6.5)° and unaffected foot (56.3 ± 3.7)° (t = 0.872, P = 0.325). There was significant difference in AOFAS between preoperative (65.1 ± 6.9) and postoperative (94.3 ± 5.5) (t = 7.672, P = 0.013). All patients returned to work and study at an average of 10 weeks (ranged from 6 to 15 weeks) and 15 patients returned to normal sports activities at 21 weeks (ranged from 18 to 24 weeks). Calf and ankle circumferences decreased by 0.45 cm (0.3 to 0.8 cm) and increased by 0.4 cm (0.2 to 0.7 cm), respectively in the injured leg as compared with the contralateral leg.
CONCLUSIONThe simplicity of the technique of minimally invasive incision and skin bridge for acute closed Achilles tendon reconstruction is an effective and reliable method with low complication.

Objective The present study was to elucidate whether there was a local renin-angiotensin-aldosterone system (RAAS)in rat hepatic stellate cells(HSC)and the immortalized rat HSC line—HSC-T6. Methods HSC was isolated by perfusion of collagenase and pronase to liver. The renin activity, angiotensin Ⅱ(Ang Ⅱ) and aldosterone(ALD) concentration in the cells were assayed by radio-immunoassay. Angiotensin converting enzyme(ACE) activity was detected by ultra-violet spectrophotography. The expression of angiotensin Ⅱ type 1 receptor(AT1R) was determined by immunohistochemistry. RT-PCR method was used to assay the mRNA expression of renin, angiotensinogen, ACE, AT1R and CYPⅡB2(the critical enzyme of aldosterone synthesis). Results Ang Ⅱ, ALD, renin and ACE activity could be detected in HSC and HSC-T6. Immunohistochemistry showed that both of them could express AT1R. mRNAs of renin, ACE, AT1R and CYPⅡB2 were also detected in both of them. Conclusions Both rat HSC and the immortalized rat HSC line HSC-T6 possessa a local RAAS.
