The screw holes of anatomic plate are oval, and longitudinal axis of the screw hole is parallel to the axis of the plate. The plate surrounding the screw hole is smooth, parallel to the longitudinal axis of the long bone. Under outside force or inside force, the top of screw can move on the smooth surface surrounding the screw hole; the movement is a reversible one. Domestic plate can fix bone fracture stably, and the outside force and inside force can result in micromovement of the fracture ends, stimulating the fracture ends and bone callus formation. Repetitive force is beneficial to bone callus response, protect fragile new vessels and bone trabecula from damage, and promote fracture healing.

Objective To study the effect of substance P (SP), calcitonin gene-related peptide (CGRP) on the blood flow and the function of endolymphatic sac (ES) in guinea pigs to clarify the pathogenesis of some inner ear diseases further.Methods The guinea pig model of superior cervical ganglion (SCG) resection was set up. The ESs of the model animals were stained by SP and CGRP immunocytochemically. The staining images were analysed by the computer. The ESBF was measured with the biologic microphere method.Results Compared with the control group, the staining of SP decreased sharply in the model group, however, the staining of CGRP remained unchanged. In the model animals, the ESBF was decreased either.Conclusion SP and CGRP could take part in the regulation of ESBF to affect the function of ES further.

Objective To evaluate serum TPSA and F/T ratio in the differential diagnosis of BPH and PCa. Methods Serum TPSA,FPSA and F/T ratio in 177 cases of BPH and 60 cases of PCa were assessed and evaluated both in patients within and outside the "gray zone". Results TPSA and F/T ratio were both significantly discriminating between benign and malignant diseases (0.010.05) whereas F/T ratio could ( P 0.05). Conclusions Serum TPSA is a prostate carcinoma marker,F/T ratio being an adjuvant marker of TPSA of importance on the differential diagnosis in patients within the "gray zone".

Switching Mechanism At 5′ end of the RNA Transcript(SMART)is a technology used in biology researching,So far,there is no review only about SMART technology.So,the aim is to investigate the research developments of principles,methods and applications of the SMART technology.Based on some researches and combined with the review of the related literature at home and abroad,it analyzed and evaluated the latest development of the research on SMART.As the applications of the SMART technology expand in many fields day after day,it has been proved that the SMART technology is a very useful and efficient skill to construct full length cDNA library.As more and more researchers know this technology,the advantages of the SMART technology become obvious,and meanwhile the disadvantages of the SMART technology also show up.That is to say,the technology needed to be improved.

Objective To investigate the expression of CXC chemokine receptor 4 (CXCR4) in clear cell renal cell carcinoma (ccRCC) and its relationship with the clinical pathological parameters of ccRCC.Methods The expression of CXCR4 was detected by immuno-histochemistry method in 63 cases of ccRCCs,20 cases of para-carcinoma tissues and 20 cases of normal renal tissues.The correlation between expression level of CXCR4 and clinical pathological parameters of ccRCC patients were analyzed,and the clinical significance of its expression in ccRCC was evaluated.Results The positive expression rate of CXCR4(49.2%) in ccRCCs was significantly higher than that in para-carcinoma tissues (15%) and normal renal tissue (10%),and the difference was statistically significant (P < 0.05).The expression level of CXCR4 and the clinical stage and pathological grade of ccRCC were correlated (P < 0.05),and was associated with lymph node transfer (P < 0.05).The CXCR4 negative group overall survival rate [55.2% (16/29)] and the average survival time(46 months) was significantly better than the positive group [38.5% (10/26),32 months;P < 0.05].Conclusions The expression level of CXCR4 in ccRCC is correlated with the clinicopathological parameters and prognosis.CXCR4 is expected to be an important marker for diagnosis and prognosis evaluation of renal cell carcinoma.

Clavicular crook plate is designed based on anatomic features of acromioclavicular joint,which matches clavicle appearance,and well attaches the shaft.Not passing through the joint,the internal fixation exhibits many advantages,such as convenient usage,reliable fixation and micromovement of fixed acromioclavicular joint.So the patients could move the joint early and avoid osteoarthritis.Allogenous tendon has abundant sources,simple sampling process,and short repairing duration and can reduce injury to patients.Cryopreserved allogenous tendon has low antigenicity and immunological refection,good histocompatibility.Reconstructed coracoclavicular ligament by allogenous tendon has good material intensity,and can meet the requirements of local stress,better substitute integrity and function of coracoclavicular ligament.Moreover,it has precise effect and simple operation.It acts as long-term fixator following plate removal,thus is important supplement of clavicular crook plate fixation.Clavicular crook plate fixation in combination with allogenous tendon transplantation reconstructs acromioclavicular joint stability,effectively provides early mechanical stability and subsequent biological stability,and maximizes restoration of acromioclavicular joint structure and function.
