Objective The color of the syphilis quality control material adopted by most detection institutes was the same with the detected serum sample and they were all colorless,transparent or light yellow.There were cases of wrong adding,missing adding or insufficient adding due to the color of quality control materials which was hard to distinguish with naked eyes.To avoid this phenomenon,a new method was established for the distinction of quality control materials.Methods A new method of syphilis quality control materials that had been improved three concentrations control materials:0.125,0.250 and 0.500 NCU/mL.The syphilis diagnostic kit that was created by Shanghai Kehua and Xiamen Yingke was adopted to conduct detection and compare results.Results The difference between stained quality control material and unstained quality control materials had no statistical significance (P＞0.05).Two different reagents were used to detect quality control materials of different concentration for 20 times and the CV were 11.7 ％-13.4％ and 9.3 ％-12.9 ％ respectively.Two different reagents were used to detect quality control materials of different concentration for 30 days and the CV range were 10.1 ％-13.4 ％ and 8.08 ％-12.8 ％.Conclusion Citric yellow staining does not influence the properties of syphilis control materials and it can be used stably for a long time.It is suitable for clinical lab application and promotion.

ObjectiveTo observe the effect of Tongxinfang on coronary collateral formation and stent-restenosis in patients with coronary artery disease after stenting.Methods61 patients with coronary artery disease were randomly divided into the treatment group (n=30), and control group (n=31). Patients of the treatment group were taking Chinese medicine Tongxinfang for six months, but cases of the control group only received basic treatment. Coronary collateral formation, stent-restenosis and ejection fraction (EF) of patients of two groups were assessed through aniograms and echocardiography before treatment and after six months.ResultsCoronary collateral formation and EF of patients of the treatment group improved significantly compared with cases of the control group (P<0.01 or P<0.05), but the minimal lumen diameter and percent of diamter stenosis were not significantly different between two groups (P>0.05).ConclusionTongxinfang can improve coronary collateral formation and EF.

ObjectiveTo observe the effect of Yiqihuoxue recipe on left ventricular remodeling after acute myocardial infarction (AMI).Methods40 patients with AMI were randomly divided into treatment group and control group with 20 cases in each group and received Yiqihuoxue recipe or fasinopril respectively for 6 months. Changes of clinical symptoms, the level of plasma angiotensin Ⅱ(ATⅡ), aldosterone (ALD), endothelin (ET) and echocardiographical indexes: left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI), ejection fraction (EF), left ventricular mass index (LvmassI), wall motion index (WMI), wall thick (WT), E/A were assessed before discharge, and in the end of 3rd and 6th month after AMI.ResultsClinical symptoms of patients of treatment group improved significantly (P<0.01). EF and E/A of all patients in two groups increased (P<0.01 or P<0.05), LvmassI and WT reduced (P<0.05), but there were no significantly differences between two groups in LVEDVI, LVESVI, EF, LvmassI, WMI, E/A and WT(P>0.05). The level of plasma ET decreased in treatment group (P<0.05), the level of plasma ATⅡ and ALD of control group decreased more than that of treatment group (P<0.05).ConclusionYiqihuoxue recipe can significantly improve clinical symptoms, cardic function, and left ventricular remodeling, showing a better clinical efficacy.

Objective To investigate the effect of traumatic lumbar puncture (TLP) on central nervous system leukemia (CNSL) in children with acute lymphoblastic leukemia and the related factors of TLP. Methods A retrospective analysis was performed from the medical records of 106 children with ALL who were diagnosed and treated from January 2010 to December 2014. The factors affecting the occurrence of TLP and the effect of TLP on the prognosis of children with ALL were analyzed. Results A total of 106 patients were treated for ALL during the study period, of which 21 cases (19.8 %) experienced TLP, median platelet count in 85 patients (80.2%) without TLP and in 21 patients with TLP was (72.50 ± 69.53) × 109/L and (31.10 ± 19.82) × 109/L (t= 2.69, P= 0.008). A receiver operating characteristic curve was constructed for predicting the risk of TLP based on platelet count. Platelet count of 34 ×109/L at the time of TLP had a sensitivity of 76%and specificity of 66%in predicting TLP. According to cerebrospinal fluid type, 1 case (4.8%) of TLP type had CNSL, and 2 cases (2.9%) of CNS1 type had CNSL (P>0.05). The 3-year event-free survival (EFS) rate in TLP group and CNS1 group had no significant difference [(82.8 ± 4.8) % vs. (74.7 ± 9.9)%, P>0.05]. Conclusions In the diagnostic lumbar puncture, platelet count<34 × 109/L is significantly associated with risk of TLP. TLP type does not contribute to inferior EFS and increase the incidence of CNSL.

Objective To demonstrate the superiority and feasibility of using bioluminescent image to monitor the islet graft after islet transplantation.Methods Diabetic models were established by intraperitoneal injection of streptomycin into mature male C57BL/6 mice.Islets were harvested from the pancreas of C57BL/6 and Bclb/c mice by digestion and purification,and transfected with Lueiferase gene.The mouse diabetic models were divided into iso-transplantaion group (n=20) and allo-transplantation group (n=7).The islets of C57BL/6 were transplanted into iso-transplantaion mice with different doses (10,50,110 and 200,n=5 in every dose),and Bclb/c mouse islets were transplanted into allo-transplantation group.The islets were transplanted into the subcutaneous fat tis- sue near left scapula.The receptor mice were scanned with CCD camera to get bioluminescent images at different scheduled time points,and the changes in random blood glucose of allo-transplantation group were observed.Results On day 6 after transplantation,the scanning image showed that the pi- xel intensity from the region of interest (ROI) was increased with the increased number of islet grafts and they had a positive correlation.The random blood glucose was reduced to the normal level in the first 2 days,and then increased again to the diabetic level on 11 days averagely,while pixel intensity from the ROI reached the peak on day 6-7,and then reduced rapidly after islet transplantation in allo- transplantation group.The beginning of pixel intensity reduction occurred on day (6.14?0.90), while that of the random blood glucose raise occurred on day (10.00?0.82) after transplantation,and the former alteration occurred obviously earlier than the latter (P
