A highly sensitive immuno-PCR assay based on sandwich ELISA and PCR was developed to detect the circulating antigen in trichinellosis. Antigens were purified from the muscle larvae of Trichinella spiralis, and the myeloma cells were fused with spenocytes immunized with T. spiralis antigens to product the specific monoclonal antibodies. Indirect ELISA was used to select the antibody-secreting hybrodoma cells. By this method of procedure, monoclonal antibody F4C6 against the T. spiralis ES antigen was obtained, which was used as the indicator antibody, while the rabbit polyclonal antibodies against T. spiralis were to be used as capturing antibodies. The plasmid Bluecript Ⅱ KS was amplified by PCR with biotin-labeled primer M13-20, and thus the biotin-labeled DNA was obtained. Both the second antibody and DNA labeled with biotin were to be linked with 100 ng/ml avidin. The whole procedures of assay consisted of two steps, in which the circulating antigens were captured by monoclonal antibody through sandwich ELISA in the first step, and the DNA linked by monoclonal antibody was amplified by PCR in the second step. The sensitivity of this method was compared with that of the ELISA assay. It was found that the measuring ranges to detect the circulating antigens in trichinellosis were 50 pg/L to 0.005 pg/L for the immuno-PCR assay, and 5 μg/L to 0.05 μg/L for ELISA assay, the former was quite higher than that of the latter. It is evident that this method is highly sensitive for the detection of circulating antigens in trichinellosis.

Objective To evaluate the value of magnetic resonance imaging features in differentiating soft tissue lipoma from well-differentiated liposarcoma.Methods MR images of 30 patients with histologically verified fat-containing tumors(22 lipomas and 8 well-differentiated liposarcomas)were retrospectively reviewed.Well-differentiated liposarcomas and benign lipomas were compared in terms of the size of the lesion,percentage of adipose component,number of thick septa,nodular and(or)patchy nonadipose component,contrast enhancement patterns and the margin characters of the lesion.Results The mean size of lipomas[(64?35)mm]was significantly smaller(t=4.263,P

Objective To explore the clinicopathological features, diagnosis and therapy for pancreatic mutinous noncystic adenocareinoma(MNAC). Methods Eleven MNAC cases treated in our hospital were studied retrospectively. The clinical and pathologic data were reviewed. Results Of the 11 patients, 6 were male and 5 were female. The age ranged from 47 to 76 years with average of 60. 5 years.The main complains included upper abdominal discomfort in 8 cases, abdominal mass in 1 case and jaundice in 2 cases. CA199 serum test was positive in all patients and 5-fold high above normal value in 6 cases. The preoperative radiography of MNAC was usually not specific. Tumors located in the head in 5 cases and in the body and tail of the pancreas in 6 cases. The diameter of the tumor was 4 - 11 cm with average of 6. 5 cm.All cases underwent operation, with radical resection in 2 cases. Liver or abdominal metastasis was found in 5 cases. Postoperative immunohistochemistry showed that MUC-1 was negative in all patients. MUC-2,PCNA and Ki-67 were positive in all patients. All 9 cases that were followed-up died within 5 -22 months,with an average survival time of 10 months. Conclusions The diagnosis of MNAC depends on pathology. Its prognosis is poor.

OBJECTIVETo analyze the genotype, epidemic pattern and the characteristics of the disease of enteroviruses during the epidemic season of hand, foot and mouth disease (HMFD) in children from 2013 to 2014 in Beijing to provide the scientific evidence for prevention and treatment of HFMD.

METHODDuring April to September in 2013 and March to October in 2014, a total of 977 throat swabs were collected from children who visited the Children's Hospital Affiliated to Capital Institute of Pediatrics, including 147 from patients with HFMD in 2013, 343 with HFMD, 201 with atypical HFMD, 83 with herpangina, 25 with fever with convulsions, 64 fever with rash and 114 with rash in 2014. Enteroviruses universal type (EV), Enteroviruses type 71 (EV71) and Coxsackievirus group A 16 (CA16) were detected by real-time RT-PCR respectively. The nucleic acid of specimens which were identified with non-EV71, non-CA16 was tested by nested PCR and analyzed by VP1 sequencing. The detection rate and epidemic pattern of different genotypes of enterovirus were analyzed among different age groups and between 2013 and 2014.

RESULTOf 977 throat swabs, 80. 1% samples were detected positive for enteroviruses. The positive rates of CA16, EV71, CA6, CA10, CA4 and other EVs were 25. 6% (250/977), 18. 9% (185/977), 20. 0% (195/977), 5. 0% (49/977), 1.5% (15/977) and 9.1% (89/977), respectively. Twenty six of the 89 other EVs included CA2, CA5, CA8, CA9, CA12, CA14, CB2, CB5, E6, E9 and E25, each genotype of which was no more than 3. The nucleotide homologies shared among CA6, CA10 and CA4 strains between 2013 and 2014 were 94. 3% - 100%, 93. 8% - 99. 1% and 92.7% - 99. 8%, respectively. The positive rates of ≤1 year group were 71. 1% (106/149), which was lower than that of other age groups (all P <0. 05), but similar to that of >5 year group (χ2 =1. 181,P = 0. 277). In 2013, the positive rate of EV was 85. 7% (126/147) and the predominant genotype was CA6 54. 8% (69/126), followed by CA16 20. 6% (26/126) and EV71 11. 9% (15/126). In 2014, the positive rate of EV was 85. 4% (293/343) in the 343 children with HFMD, the predominant genotypes were CA16 with the positive rate of 42. 7% (125/293), EV71 with 38. 2% (112/293) and CA6 with only 11. 3% (33/293). In 2014, the positive rates of EV in 201 atypical HFMD, 83 herpangina, 25 fever with convulsions, 64 fever with rash and 114 rash were 83. 6% (168/201), 80. 7% (67/83), 76. 0% (19/25), 64. 1% (41/64) and 60. 5% (69/114), respectively. All genotypes of enteroviruses peaked mainly during May to August every year, but there were no obvious epidemiological pattern about each genotype.

CONCLUSIONCA6 became the main causative agent of HFMD in 2013, however, CA16 and EV71 predominated again in 2014 in Beijing. The clinical manifestations caused by CA6, CA10, CA4 and other genotype of enteroviruses differed from EV71 and CA16. Besides EV71 and CA16, more attention should be paid to CA6, CA10, CA4 and other type of enteroviruses.
