OBJECTIVE:To investigate the clinical characteristics and rules of allergic reaction caused by anti-copper treat-ment with Sodium dimercaptoproane sulfonate(DMPS)injection,and to provide reference for diagnosis,treatment and monitoring of drug-induced allergic reaction. METHODS:By using retrospective analysis,allergic reaction reports of DMPS injection were se-lected from our hospital during Jan. 2013-Dec. 2015 were analyzed statistically. RESULTS:A total of 131 cases of allergic reaction were reported. The average age of the patients was(23.26±9.63)years old,mainly concentrated on 10-39 years old(87.79%). Al-lergic reaction mainly occurred in the first and second courses of treatment,accounting for 71.76%. For systems-organs involved, skin and its appendages disorders had the highest proportion (85.90%),being mainly the lesion of limbs (27.45%) and body (22.22%) involved;followed by systemic damage (12.33%). Clinical manifestations of systemic impairment were mainly fever, with rash or itching at the same time frequently. 131 patients had good outcome after treatment. The symptoms of 115 patients (87.79%)disappeared in 7 d. Serious cases accounted for 25.19%. The proportion of drug allergy history,the rate of anti-copper treatment failure with allergy prevention or desensitization therapy,and symptom duration in patients with severe ADR were higher or longer than that in general ADR cases,the difference was statistically significant(P<0.05). CONCLUSIONS:The allergic reac-tion of DMPS injection increased the difficulty of anti-copper treatment. ADR monitoring should be strengthened in the process of using DMPS,specially for the history of allergies and the first,second treatment courses of patients.

Objective To study imaging features of primary chondrosarcomas and the correlation with pathologic basis.Methods The imaging materials of primary chondrosarcoma in 21 cases were retrospectively analyzed and correlated with pathological results. Results In 21 cases,the pathologic classifications were as following:15 cases of conventional intramedullary,1 case mesenchymal,2 cases myxoid,1 case dedifferentiated and 2 cases with no subtypes.For 6 cases of conventional intramedullary in gradeⅠand 8 cases in gradeⅡ,bone destruction in varying degrees accompanied with soft tissue mass(n=1 1),regional thickening cortical bone (n=2),“ring-arc”like matrix mineralization(n=6),amorphous (n=3)were showed on X-ray study.CT were performed,in 6 cases in gradeⅠ,6 cases in gradeⅡ and 1 case in grade Ⅲ in which there were intraosseous calcification (n=12),regional thickening cortical bone (n=2)and periosteal new bone formation (n=1).Lesions appeared expansive or osteolytic bone destruction accompanied with soft tissue mass on CT and MRI srudy MRI were performed in 5 cases in gradeⅠ and lesions were heterogeneous high signal intensity on T2 WI with spot like and “ring-arc”like low signal intensity.Conclusion Pathologic classifications and grading of primary chondrosarcoma may be presumed with imaging features.Pathologic characteristic manifestions on MR are superior to that on CT and X-ray.

Objective To observe the positive rate of plasma cytomegalovirus DNA(CMV‐DNA) level after allogenic hema‐topoietic stem cell transplantation (allo‐HSCT) ,analysis and explore the risk factors related to CMV infection .Methods Choose 30 patients who had performed allo‐HSCT in our department from July 2012 to September 2014 .PCR were used regularly to detect the plasma CMV‐DNA levels in these patients .The regular monitoring times were as follow :the first month(once a week) ,the second to third month(twice a week) ,the fourth to sixth month(once a month) after allo‐HSCT respectively .The positive rates were coun‐ted in every period .Results Thirteen patients had CMV infection ,and the infection rate were 43 .3% .In the first month ,there were 4 cases (13 .3% )whose plasma CMV‐DNA levels were positive ,however ,the positive cases in the second month ,the third month , the fourth month ,the fifth month and the sixth month were 11(36 .7% ) ,2(6 .7% ) ,0 ,2(6 .7% ) and 0 respectively .Statistical data showed that it was in the second month after allo‐HSCT that the CMV‐DNA positive rate was higher than other periods .The anal‐ysis suggested that the positive rate of CMV‐DNA related to the administration of rabbit anti‐human thymocyte globulin(ATG) ,ba‐siliximab ,and the occurrence of acute graft versus host disease(GVHD) ,there were no relationship among gender ,age ,risk stratifi‐cation of primary disease ,HLA condition ,preparative project ,recovery time of neutrophile granulocyte .Conclusion It is necessary and beneficial to monitor blood CMV‐DNA level regularly and take treatment early to avoid CMV related comobidity after allo‐HSCT .

Objective To evaluate the clinical efficacy of MRA in the arteries of the pelvis and lower extremity with automatic table movement (MobiTrak).Methods 12 cases suspected of pelvis and lower extremity artery diseases underwent dynamic 3D contrast enhanced MRA and automatic table movement at the same time.Three cases underwent artery angiography,four cases were detected by operation.Results All diseased arteries were well demonstrated.Among them,lower extremity artery occlusion 8,failing vascular grafts 2,artery aneurysms 2.Conclusion Automatic table movement is of value in assessing pelvis and lower extremity artery diseases accurately.And it is a reliable and potential new technique.

Objective To establish an UPLC method for determination of Triptolide in serum and explore its pharmacokinetics in patients with rheumatoid arthritis after oral administration of tripterygium glycosides tablet. Methods Three patients with rheumatoid arthritis were enrolled. Using Estazolam as internal standard, serum was extracted with acetic ether, and determination was performed on column of Waters Acquity C18 (2.1 mm×100 mm, 1.7 μm) with mobile phase consisted of acetonitrile-0.1% glacial acetic acid (30∶70) at the flow rate of 0.2 mL/min. The column temperature was 30 ℃, and the detection wavelength was set at 220 nm. The serum concentration of Triptolide was processed by DAS 2.1.1 computer program. Results Triptolide was well-separated from internal standard, and the retention time were about 4.9 min and 8.9 min, respectively. Linear range of Triptolide was 13.13-840.00 ng/mL. RSD of intra-day and inter-day were lower than 15%and the recoveries were 88.25%-99.33%. Pharmacokinetic parameters were as follows:Cmax was (159.97±42.43) ng/mL, Tmax was (1.33±0.58) h, T1/2βwas (7.51±2.26) h, and AUC0-12 h was (1131.12±89.20) mg?h/L, respectively. Conclusion Pharmacokinetics of Triptolide conformed to two compartment model. Triptolide can be quickly absorbed, and exists differences among individuals.

A high Streptolydigin-producing strain Streptomyces lydicus AS 4.2501-L8 with genetic stability was obtained from the original strain S. lydicus AS 4.2501-P28 by mutagenesis with UV and acridine orange, followed by resistance selection. Its yield of Streptolydigin was 177.0 ?g/mL, 96.2% higher than the original strain.

OBJECTIVE:To systematically review the efficacy and safety of Xiaoke pill versus glibenclamide in the treatment of type 2 diabetes mellitus,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from Medline, PubMed,EMBase,Cochrane Library,CBM,CJFD,Wanfang Database and VIP Database,randomized controlled trials (RCT) about the Xiaoke pill(test group)versus glibenclamide(control group)in the treatment of type 2 diabetes mellitus were enrolled. Meta-analysis was performed by using Rev Man 5.2 software after document selection,data extract and quality assessment by Co-chrane systematical evaluation. RESULTS:A total of 15 RCT were included,involving 3 319 patients. Results of Meta-analysis showed the hemoglobin A1c (HbA1c) level [MD=-0.39,95%CI(-0.75,-0.02),P=0.04],fasting plasma glucose (FPG) level [MD=-0.70,95%CI(-1.27,-0.12),P=0.02],2 h PG[MD=-0.87,95%CI(-1.55,-0.20),P=0.01],incidence of thirst with desire for drinks [RR=3.35,95%CI(1.92,5.85),P<0.001],incidence of tiredness and debilitation[RR=5.74,95%CI(3.52, 9.36),P<0.001] and incidence of hypoglycemia [RR=0.67,95%CI(0.49,0.91),P=0.01] in test group were significantly lower than control group,the differences were statistically significant. CONCLUSIONS:Xiaoke pill has better efficacy and safety than glibenclamide in the treatment of type 2 diabetes mellitus,can obviously improve the HbA1c,FPG,2 h PG tevel and TCM symp-toms.
