Objective To compare the efficiency difference of 3 serological methods in syphilis blood SCreening,and then select the most proper method to prevent the transmission of syphilis via blood.Methods The samples of 2 000 blood donors were tested by TP-ELISA,TRUSlT and TPPA.Those positive samples detected by TP-ELISA and TRUST were confirmed by TPPA again.Results Of the 2 000 samples,11 samples were-TP-ELISA positive in which 8 samples were confirmed positivewith TPPA;2 samples were TRUSlT positive and both the two samples were confirmed positive withTPPA;and 8 cases were TPPA positive.There was obvious difference in detection rate between TRUST and TP-ELISA method(P

ObjectiveThe present study aimed to determine whether or not dual paroxysm proliferator-activated receptor (PPAR) agonist,WY14643,improved the dysfunctioned vascular endothelium in hypertension by reducing endothelium-derived contracting factors ( EDCFs ),and to explore the molecular mechanism it was involved in.MethodsIsometric tension in isolated thoracic aortic rings of spontaneously hypertensive rats was recorded.Endothelium-dependent contractions evoked by acetylcholine in the presence of L NAME were reduced by fenofibrate.Cyclooxygenase 1 ( COX1 ) activities were determined by analyzing the peroxidase activity of cyclooxygenase colorimetrically by using ELISA kit.ResultsCompared to the control group,WY14643 significantly decreased the vasoconstriction in aorta of the SHR rats(P=0.014).PPARα antagonist MK866 enhanced the vascular contractility of SHR rats that were incubated with 10.0μmol/L WY14643( P=0.021 ).PPARΥ antagonist GW9662 did not significantly affect the vascular contractility of SHR rats that were incubated with 10.0 μmol/L WY14643( P=0.061 ).The levels of serum PGFlα(P=0.012),2α( P =0.019) and TXB2(P=0.023) in SHR rats incubated with 10.0 μmol/L WY14643 were significantly lower than the control group,respectively.Under the condition of the existence of vascular endothelium,the expression of COX-1 in SHR rats incubated with WY14643 was significantly lower than that in SHR rats incubated without WY14643 (P=0.017).ConclusionsThose data showed that WY14643 reduced the release of EDCFs,it suggests that WY14643 protects against vascular diseases through the PPAR activators in spontaneous hypertension.

Objective: To estimate the clinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolys-is agents in bone metastatic carcinoma. Methods: Seventy-one patients with bone metastatic carcinoma were divided into 2groups and treated with protocol A or B, respectively. The protocol A was a combination of chemotherapy with osteoblastpromoting and anti-osteolysis agents, the protocol B was a combination of chemotherapy with antiosteolysis agent only. Theefficacies of the 2 protocols were compared and studied. Results:The effect of A was more remarkable than that of B in re-lieving bone pain and enhancing bone repair. No severe adverse effect of these agents was found in therapy. Conclusion: Theclinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolysis agents in bone metastatic car-cinoma was definite, the osteoblast promoting agent as an effective adjtmctive agent can be used not only in osteoprosis butalso in bone metastatic carcinoma.

Diabetic retinopathy ( DR ) is one of the main blinding eye diseases for people over the age of 50, and diabetic macular edema ( DME) is the leading cause of vision loss is DR patients. The early diagnosis and early treatment is important. As OCT and FFA, mfERG, especially the retinal thickness, volume, retinal edema index quantitative indicators such as objective evaluation of macular edema, embodies the new progress of retinal imaging technology in recent years. OCT is a non -contact clinical application in recent years, noninvasive, high resolution of ophthalmic imaging examination, can do it on retinal ultrastructure observation and quantitative analysis, and the technology is relatively mature, become a routine inspection diagnosis of macular edema. Laser photocoagulation, intravitreous injection with Ranibizumab and vitrectomy is nowadays the important means for the treatment of intractable macular edema.
