Objective To explore the feasibility of the Coapresta2000 automatic coagulation analyzer for detecting C‐reactive protein(CRP) .Methods The performance of the Coapresta2000 automatic coagulation analyzer for detecting CRP was analyzed ,in‐cluding accuracy ,linearity ,precision ,carryover rate and the correlation between the Ottoman automatic special protein real time ana‐lyzer and the Coapresta2000 automatic coagulation analyzer .Results The men recovery rate of 3 batches of reagent by the Coapres‐ta2000 automatic coagulation analyzer for detecting CRP for detecting plasma CRP was 106 .0% with better accuracy ;the within‐run precision was less than 10% and the inter‐day precision was less than 15% ;the carryover rate was 0 .32% ;the related equation in the Ottoman automatic special protein real time analyzer and the Coapresta2000 automatic coagulation analyzer for detecting plas‐ma CRP was Y=0 .001 2X+0 .489 ,the correlation coefficient was r2 =0 .997 5 ,the difference was not statistically significant(P>0 .05) .The CRP results of plasma sample detected by these two instruments was highly correlative ;the linearity in the Coapres‐ta2000 automatic coagulation analyzer for detecting CRP was 0-200 mg/L .Conclusion The Coapresta2000 automatic coagulation analyzer for detecting CRP has better within‐run precision ,low carryover rate ,high correlation with the Ottoman automatic special protein real time analyze ,which has a value for further study .

OBJECTIVETo compare the efficacy difference between acupotomy and acupuncture in the treatment of avascular necrosis of femoral head at the early and middle stages.

METHODSThe randomized controlled prospective study method was adopted. Sixty cases of avascular necrosis of femoral head at Ficat-ArletⅠto Ⅱ stages were randomized into an acupotomy group (32 cases) and an acupuncture group (28 cases) by the third part. In the acupotomy group, the acupotomy was adopted for the loose solution at the treatment sites of hip joint, once every two weeks, totally for 3 times. In the acupuncture group,points around the hip joint were selected and stimulated with warm acupuncture therapy, once every day, for 6 weeks. Harris hip score was observed before and after treatment. The efficacy was evaluated in the two groups.

RESULTSHarris hip score was improved significantly after treatment in the two groups (both<0.05). The result in acupotomy group was better than that in the acupuncture group (<0.05). The effective rate was 90.6% (29/32) in the acupotomy group, better than 75.0% (21/28) in the acupuncture group after treatment (<0.05).

CONCLUSIONSHarris hip score and the effective rate in the acupotomy group are better than those in the treatment with routine acupuncture for avascular necrosis of femoral head at the early and middle stages.
