Loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification method, which amplifies DNA with high specificity, sensitivity, rapidity and efficiency under isothermal conditions using a set of four specially designed primers and a Bst DNA polymerase with strand displacement activity. The basic principle, characteristics, development of LAMP and its applications are summarized in this article.

Objective To investigate the immunofluoresce nt and immunoblotting features of paraneoplastic pemphigus(PNP).Methods Sera were tested by indirect immunofluorecence(IIF)and immunoblotting(IB)in four patients with PNP.Results Binding of IgGand C3to the intercell ular spaces of epidermis was found in IIF with rat bladder as substrate.The titers decreased after the excision of tumo rs.The autoantibodies also bound to sub-strates of the epithelia of human ski n,rat tongue and esophagus in those p atients.The patients' sera recogni zed 210kD and 190kD antigens from human kera tinocyte extracts with IB analysis.Conclusions IIF with rat bladder as substrate can be used a screening test for PNP.PNP tends to involve epithelia of mucosa.The results of IB test m ay confirm the diagnosis of PNP of the 4p atients.[

OBJECTIVE:To optimize the inclusion process of the volatile oil of Pogostemon cablin and Acorus tatarinowii in Xiaoyu anshen capsule.METHODS:The inclusion process was carried out by saturated water solution method.And the inclusion process was optimized by orthogonal experiment with the inclusion ratio and yield of the volatile oil as indexes taking the ratio of volatile oil to ?-CD,the temperature and the time of inclusion as factors.The physical phase of the inclusion complex was detected by differential scanning calorimetry(DSC).RESULTS:The optimum inclusion process was established as follows:the ratio of oil to ?-CD=1∶8;the ratio of water to ?-CD=10∶1;the inclusion time was 1h and the inclusion temperature was 50 ℃.The inclusion rate was as high as 90%.The DSC revealed that a new physical phase has been formed for the inclusion complex.CONCLUSION:The intermolecular inclusion complex with good stability and high yield of volatile oil could be obtained from the optimized inclusion process.

Objective To study the effect of Src tyrosine kinase inhibition on subcutaneously transplanted tumor of human lung adenocarcinoma in mice and its mechanism. Methods For the subcutaneously transplanted tumor model, A549 cells or PC-9 cells were inoculated into SCID mice by subcutaneous injection. Immunohistochemistry was used to show the effect of Src tyrosine kinase inhibition on proliferation index (Ki-67 staining) and microvessel density (CD31 staining) of subcutaneously transplanted tumor of human lung adenocarcinoma in mice. Results Subcutaneously transplanted tumor of PC-9 cells was sensitive to src tyrosine kinase inhibitor. There was significant difference between treatment group and control group (P <0.01). There was significant difference between the two treatment group too (P <0.01). Stopping treatment for 1 week, the inhibition rate of tumor growth were 33.19 % and 84.79 % in 10 mg·kg-1·d-1 and 50 mg·kg-1·d-1 treatment group, respectively. The same treatment was less effective to subcutaneous tumors produced by A549 cells. Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced the proliferation index of subcutaneously transplanted tumor produced by PC-9 cells (P<0.01) and tended to reduce the proliferation index of subcutaneously transplanted tumor produced by A549 cells (P >0.05). Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced micro vascular density in both PC-9 and A549 induced subcutaneous tumors (P <0.05). Conclusion Inhibition of Src tyrosine kinase could suppress the progression of subcutaneously transplanted tumor, not only by the inhibition of cell proliferation of lung adenocarcinoma cells directly, but also by the inhibition of angiogenesis indirectly.

Objective:To investigate the existence of side population cells with the potency of stem cells in human gallbladder carcinoma cell line GBC-SD and the differences in ABCG2,Oct-4 and CD34 expression among SP cells,non-SP cells and GBC-SD cells.Methods:SP and non-SP cells were sorted from GBC-SD cells by fluorescence-activated cell sorting(FACS).The expression of ABCG2,Oct-4 and CD34 in SP cells,non-SP cells,and GBC-SD cells was detected by reverse transcription-polymerase chain reaction(RT-PCR),Western blot,flow cytometry(FCM)and immunofluorescence chemistry.Results:SP cells with stem cell potency were isolated from GBC-SD cells with a proportion of(0.64±0.08)%.The metastatic ability of SP cells was obviously higher than that of non-SP cells and GBC-SD cells(P<0.05).The expression of ABCG2 was significantly higher in SP cells than in non-SP cells and GBC-SD cells[(89.56±3.86)%vs.(1.32±0.49)%and(12.37±1.61)%,P=0.001].The expression of Oct-4 in these cells was(94.87±1.40)%,(88.16±2.34)%and(90.17±1.61)%,respectively(P>0.05).CD34 was neady absent in these cells on protein level[(1.78±0.51)%vs.(0.63±0.21)%and(0.96±0.381)%,P>0.05)],but it was highly expressed in non-SP cells and GBC-SD cells and absent in SP cells off mRNA leve;.Conclusion:SP calls which hava the potency of stem cells,exist in human gallbladder carcinoma GBC-SD cell line and have the phenotype of ABCG2+Oct-4+CD34-.

Objective: To improve the understanding of the clinical feature and early diagnosis of relapsing polychondritis(RP). Method: Eleven patients with RP were analyzed retrospectively and the reported literatures were reviewed. Result: Nine cases had initial involvement of auricular cartilage while two polyarthritis. The treatment of 2RP patients with respiralory tract involvement was invalid and 1 patient died. Nine cases were initially misdiagnosed, with a misdiagnosis rate of 81.82%. Conclusion: RP involves cartilage and connective tissue. The prognosis with respiralory tract involvement is poor. RP is a sort of paroxysmal and progressive inflammation involving cartilages all over the body with a variety of clinical manifestations. Early diagnosis of RP is based on full understanding of its clinical features.

Objective To investigate the injury characteristics and prognostic risk factors of patients with craniocerebral injury so as to provide some suggestions for the improvement of medical prevention,intervention and treatment measures.Methods Trauma database system was applied to collect the medical records of 661 patients with traumatic brain injury admitted to the Department of Neurosurgery of 105th Hospital of Hefei in 2009.Their general conditions,injury characteristics and outcomes were analyzed and the risk factors affecting their outcomes were investigated by Logistic regression analysis.Results Of the patients with craniocerebral injury,the males accounted for 70% (463/661).The patients at 45 years old or so had the highest incidence of craniocerebral injury.Patient number in the second half of one year was 1.65 times more than that in the first half of one year (412/249 ).Most patients were injured from traffic accidents (87.7%,580/661 ) and 512 patients (77.5%) suffered from multiple injuries.ISS,injury causes,age and injury incidence quarters showed close correlation with the final outcome.Conclusions The patients with craniocerebral injury demonstrates distinctive characteristics in aspects of gender,age,incidence time,injury causes,and multiple injuries,but the ultimate outcomes are related to the injury severity,injury causes,age and other factors.
