Objective To investigate the clinical application value of fluorescence PCR in vitro diagnosis(IVD)reagent kits in the HLA-B27 detection by comparing 2 kinds of HLA-B27 IVD reagent kit approved by CFDA.Methods A total of 573 clinical blood samples were collected and detected for HLA-B27 by the approved reagent kits based on the fluorescence PCR technique and the flow cytometry.The samples with inconsistent testing results by the two kits were further confirmed by the PCR sequencing.At the same time,about 5% samples of the positive results detected by the fluorescence PCR method were extracted for conducting the re-testing.Results Among 573 samples,191 samples were HLA-B27 positive and 382 cases were HLA-B27 negative by flow cytome-try;the same samples had 194 cases of HLA-B27 positive and 379 cases of HLA-B27 negative by real-time PCR.With flow cytome-try as reference of the final results,the positive coincidence rate of the two kinds of kit was 96.33%(184/191),the negative coinci-dence rate was 94.76%(362/382),27 samples had inconsistent results from the two kinds of assay(accounting for 4.71% of the to-tal number of samples),the total coincidence rate was 95.29% [(184+362)/573],the Kappa value was 0.896(P =0.02);the chi-square test P =0.021,the two kinds of testing method had the high consistency,but the differences existed in the testing results. The re-testing results by PCR sequencing(including 27 samples with inconsistent results by two kinds of kit)were entirely consist-ent with the fluorescence PCR testing results.Conclusion Compared with the authority method flow cytometry for HLA-B27 tes-ting in clinic,the fluorescence PCR kit may present more accurate judging ability for the HLA-B27 testing on the basis of ensuring the higher consistency of the testing results,is easier compared with the sample preparation and operating procedures,and has the stronger clinical application value and prospects s.

Objective To investigate the relationship between the cell cycle blocked by hyperthermia and the expression of rhythm gene Bmall in gastric cancer MKN28 cells so as to provide the academic evidence in hyperthermia therapy for gastric cancer.MethodsThe MKN28 cells were resuscitated and cultured in vitro.In control group MKN28 cells were cultivated at 37 ℃.In experimental groups MKN28 cells were heated at 43 ℃ for different durations.The cell morphology was observed by microscopy.Methylthiazdyl tetrazolium (MTT) assay was adopted to evaluate the inhibitory effect of the cell line.The flow-cytometry was adopted to observe the influence on the cell cycle.The Bmall mRNA expression was investigated by real-time quantitative reverse transcription-polymerase chain reaction ( RT-PCR).ResultsThe remarkable changes of cell morphology were observed by microscopy after exposure to heating.According to the data of MTT assay,37 ℃ heating could not inhibit the proliferation of MKN28.The inhibitive rates of cell growth after 0.5 h,1 h,l.5 h at 43 ℃ was (21.76±5.46)％,(25.30 ±4.36)％ and (27.62 ± 3.78 )％,respectively.Results from flow-cytometry showed that G0/G1 phase cells in lh at 43 ℃ were remarkably less than those in the control group.However G2/M cells were significantly more than those in the control group.The mRNA expression of Bmall was the lowest when heating lh at 43 ℃ as compared to the control group.ConclusionsHyperthermia could induced the cell cycle changes and the expression of Bma11 in gastric cancer MKN28 cells.

[Objective]To discuss the anatomy and etiology of cubital tunnel syndrome.[Method]The clinical data and surgical findings of sixty five cubital tunnel syndrome cases were analyzed,and the per-operative electromyogram results of twenty five cases were studied.[Result]Hypertrophy of arcuate ligament resulted in compression and abrasion of ulnar nerve in sixty patients;we found that the ulnar nerve conduct velocity decreased(the average speed was 27.97 m/s),motional amplitude also decreased(the average voltage was 1.95 mv),and latent period prolonged(the average time was 5.41 ms)after pre-operative electromyogram.[Conclusion]The major etiology of cubital tunnel syndrome is chronic injury with sustained compression of ulnar nerve around elbow joint.Careful physical examination of ulnar nerve function and pre-operative electromyogram will help us to diagnose the cubital tunnel syndrome.Cubital tunnel syndrome should be differentiated from tardy ulnar nerve palsy of other sites.

OBJECTIVE:To investigate osteogenic and chondrogenic differentiation of adipose-derived stem cells following a short time induction with bone morphogenetic protein 2(BMP-2) or BMP-7.METHODS:The subcutaneous adipose tissue was obtained from adult New Zealand rabbits under aseptic condition,and cultured in vitro with collagenase digestion.All cells were divided into 3 groups:in the BMP-2 group,cells were cultured with medium containing 0.1 g/L vitamin C,10 mmol/L?-sodium glycerophosphate and 10?g/L BMP-2 for 10 minutes,followed by 4-14 days inoculation with density of 18?104 cells per pore.In the BMP-7 group,cells were cultured with BMP-7 with the same methods as BMP-2 group.The cells were cultured with simple culture medium in the control group.RESULTS:Compared to the control group,the number of adipose-derived stem cells,protein level and ALalkaline phosphatase(ALP) activity of BMP-2 and BMP-7 groups was up-regulated 1.78-1.79,1.15-1.95,and 32-40 times,respectively.At days 4 after a 15 minutes induction,the runx-2 gene expression,osteopontin gene,and biglycan gene were increased 1.9,2.2 and 1.3-1.7 folds than that of the control group.Meantime,only the biglycan gene expression was increased 1.3-1.7 folds in the BMP-7 group,the runx-2 gene expression,osteopontin gene was not changed.At day 14 after a 15 minutes induction,there was no alter of runx-2,osteopontin,biglycan,as well as aggrecan gene expression in the BMP-2 group;while down-regulated runx-2,osteopontin,biglycan 1.8,5.0 and 1.7 folds,with increased aggrecan gene in the BMP-7 group.CONCLUSION:Following a short time induction,BMP-2 can stimulate runx-2 and osteogenic expression at 4 days after re-culture,whereas BMP-7 down-regulate genes expression at days 14,yet down-regulate aggrecan mRNA expression.
