Objective To study the value of detection of C- reactive protein(CRP), serum glucose concen-tration and APACHE Ⅱ grade for estimating inflammation, pathogenetic condition and prognosis of systemic inflam-matory response syndrome (SIRS) patients.Methods 50 SIRS patients in ICU were selected and were divided into S1 and S2 subgroup according to SIRS diagnosis standard, and 18 patients developed MOBS.30 patients without SIRS, were selected as control group.Detection of CRP, serum glucose concentration and APACHE Ⅱ grade were per-formed.Results CRP(76.19±11.98 mg/L vs.14.04±5.70 mg/L) ,serum glucose concentration(7.10±1.30 mmol/L vs.5.32±1.09 mmol/L) and APACHE Ⅱ grade (20.06±6.39 vs.7.90±3.54) of SIRS group were higher than that of non-SIRs group (P<0.01).CRP, serum glucose concentration and APACHE Ⅱ grade all are higher in group S2 than that of group S1 (91.25±9.89 mg/L vs.62.29±10.38 mg/L,8.32±2.40 mmol/L vs.7.10±1.69 mmol/L,26.72±5.14 vs.18.37±5.70).MOBS incidence and case fatality in S2 subgroup (12/15 and 6/35) were higher than that of S1 subgroup(10/15 and 3/35 ) (P<0.01 ).Conclusion CRP, serum glucose concentration and APACHE Ⅱ grade are increased in SIRS patients and with their increasing, MOBS incidence and case fatality were also increasing.CRP, serum glucose concentration and APACHE Ⅱ grade are significant factors in estimating SIRS patients pathogenetic condition and their prognosis.

Objective To investigate the application value of color Doppler ultrasonography in the diagnosis and treatment of uterine scar pregnancy. Methods The sonographic characteristics of 34 patients of uterine scar pregnancy were analyzed. The changes of blood flow and the resistance index (RI) were compared before and after conservative treatment. Meanwhile, the therapeutic effect was evaluated referencing to the changes of β-hCG in blood. Results Uterine scar pregnancies were classfied into three subtypes according to ultrasonic characteristics: Type Ⅰ: embryo sac (n=16 cases);Type Ⅱ: asymmetrical mass (n=14);Type Ⅲ: mixed type (embryo sac+asymmetrical mass, n=4). Peri-myometrium of the gastrula and the mass had abundant blood flow and lower RI before treatment, while rare blood flow and middle RI were found 4 weeks after treatment. There was statistical significance in the change of RI between before and four weeks, after treatment. Conclusion Uterine scar pregnancy has characteristic ultrasonogram. Color Doppler ultrasound may precise diagnose and localize uterine scar pregnancy, playing an important role in guiding the conservative treatment schedule, evaluating the therapeutic effect and following-up of these patients.
