Objective To evaluate the diagnostic and prognostic evaluation of Procalcitonin (PCT)levels detection for elderly patients with severe pulmonary infection.Methods 60 elderly patients with severe pulmonary infection were selected,as the infected group,wherein 45 cases with bacterial infection,15 cases with non -bacterial infections.Another 60 cases elderly patients excluded infectious diseases were selected as the control group.PCT,CRP and WBC levels in two groups were detected and compared.The infection group was randomly divided into two groups,each of 30 cases,the control group received conventional anti -infection treatment,while the observation group developed solutions to optimize antimicrobial drugs by detecting changes in PCT and CRP.Antibiotic course,antimi-crobial drug costs,superinfection and adverse reaction rates in two groups were recorded and compared.Results PCT,CRP levels and WBC in the infected group were (17.4 ±11.3)ng/mL,(43.5 ±18.7)mg/L and (10.4 ± 7.3)×109 /L,which in the control group were (0.4 ±0.2)ng/mL,(6.3 ±3.6)mg/L and (5.4 ±1.4)×109 /L,the difference was statistically significance (t =7.369,9.570,3.295,all P <0.05 ).PCT levels of bacterial infection group was (27.2 ±14.7)ng/mL,which in non -bacterial infection group was (8.2 ±2.7)ng/mL,the difference was statistically significant (t =7.369,9.570,3.295,all P <0.05).Antibiotic course,antimicrobial drug costs,superin-fection and adverse reactions in the observation group were significantly lower than those in the control group,the difference statistically significant (t =6.994,27.71,χ2 =6.171,6.984,all P <0.05).Conclusion PCT detection has an important value of infection diagnosis especially in elderly patients with severe pulmonary infection,and can be used as the basis for antibiotic treatment.

Objective To observe and compare the clinical efficacy,recurrence rate and safety of differ-ent courses of inhalation fluticasone propionate in treatment of children with cough variant asthma. Methods A total of 101 children with cough variant asthma in our hospital were randomly divided into three treatment groups,all with the same therapy drug -fluticasone propionate and with the treatment time of two months, six months and nine months respectively. Clinical efficacy and treatment compliance were followed up during the treatment. After discontinuation,observation for the relapse of cough was followed up for 6 months. In inhalation therapy before and after,bone mineral density( BMD) and blood cortisol,electrocardiogram were monitored re-spectively to observe its safety. Results Three groups of children with cough were all get effective control,with no significant difference(H=5. 2894,P=0. 0710). The two months treatment group(A group)was more easy to relapse than the six months treatment group( B group) and the nine months treatment group( C group) after drug withdrawal,statistically significant(χ2 =4. 858 1,P=0. 027 5;χ2 =4. 482 6,P=0. 034 2). But after drug with-drawal,there was no significant difference in the rate of relapse in B and C group(χ2 =0. 022 2,P=0. 881 4). There were few changes in laboratory values about morning serum cortosol concentrations. There was no signifi-cant decrease in BMD after treatment. No other adverse events were observed in this study. Conclusion Flutica-sone propionate inhalation treating children cough variant asthma has good effection. A long period of treatment scheme(6 months)has better curative effect and lower recurrence rate after drug withdrawal.

Objective To investigate the interference effect of calcium dobesilate on serum creatinine levels by Sarcosine oxidase-based assay.Methods 1.Interference test in vivo:Ten patients with chronic renal diseases from Huangshi second hosptial were recruited.Serum creatinine (sarcosine oxidase method,Scr1 ; deiminase method,Scr2),urea,and cystatin C were detected and compared before and after one week administration of calcium dobesilate; 2.Interference test in vitro:to detect whether 100 mg/L calcium dobesilate has any interference with Scr1 and Scr2; 3.Dose-dependent interference test:To detect the interference effect of different concentrations of calcium dobesilate (1.25-20.0 mg/L) on different creatinine concentrations (404.5 μmol/L or 65.9 μmoL/L) measured by sarcosine oxidase assay.Bias within 3.5％ or 6.63 μmol/L of creatinine levels was clinically acceptable.Statistical comparisons were made using Wilcoxon rank-sum test.Results There was significant difference of sarcosine oxidase-based serum creatinine levels between before and after one week administration of calcium dobesilate (P ＜ 0.05),while no significant differences were observed for deiminase-based serum creatinine levels,urea and estimated GFR values (P ＞ 0.05).Interference test showed that 95％ confidence interval of interventional value (Dobs) of calcium dobesilate (100 mg/L) was (-173.9 ± 2.86) μmol/L for the sarcosine oxidase assay and (1.21 ± 3.14) μmol/L for deiminase method,indicating that calcium dobesilate caused a significant negative effect on the former enzymatic assay but not the latter one.In the dose effect interference test of calcium dobesilate,the regression equations were:Y =-2.7649X-0.0782 (R2 =0.998,F =7943.4,P =0.000) for high creatinine levels and Y =0.0263X2-1.6394X-0.2754 (R2 =0.996,F =2546.7,P =0.000) for low creatinine levels.The interference effect was less than the predetermined d with the calcium dobesilate concentrations of 4.4 mg/L in high concentration specimen and 3.5 mg/L in low concentration specimen.Conclusions Calcium dobesilate has a significant negative interference with serum creatinine detected by the sarcosine oxidase method,which leads to the bias of creatinine in patients with renal insufficiency.Hence,sarcosine-oxidase-based creatinine levels should be cautious when calcium dobesilate was used,and further check with another assay is necessary if possible.

Objective To evaluate the efficacy of different doses of dezocine for decreasing the minimum alveolar concentration (MAC) of desflurane.Methods ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 50-70 yr,undergoing elective lower abdominal surgery performed under general anesthesia,were divided into 4 groups:control group (group C)and different doses of dezocine groups (D1,D2 and D3 groups).Before induction of anesthesia,in D1,D2 and D3 groups,dezocine 0.050,0.075 and 0.100 mg/kg were intravenously infused,respectively,while in group C,the equal volume of normal saline was given instead of dezocine.The adverse reactions were observed.Propofol 3 mg/kg was given for induction of anesthesia 15 min later until patient' s consciousness and spontaneous respiration disappeared.Laryngeal mask airway was inserted and the patients were mechanically ventilated.Up-and-down sequential allocation was used to determine the MAC of desflurane during maintenance of anesthesia.The end-tidal concentration of desflurane was set at 8.0％ and maintained at this level for at least 5 min before skin incision in the first patient.Each time the concentration of desflurane increased/decreased in the next patient depending on whether or not the body movement developed.The ratio between the two successive concentrations was 0.9.The point between the positive response and negative response served as a cross-over point.After at least 7 independent cross-over points were observed in each group,the experiment was stopped.The MAC and 95 ％ confidence interval of desflurane were calculated.Results No adverse reactions developed in each group.The MAC of desflurane was significantly lower in D1-3 groups than in group C,in groups D2.3 than in group D1,and in group D3 than in group D2.Conclusion Dezocine 0.100 mg/kg injected intravenously at 15 min before induction of anesthesia provides a better efficacy for decreasing the MAC of desflurane in the patients.

Ninety fresh umbilical cords of newborns were harvested and dissected. There were 86 cords with double arteries and single vein and 4 cords with only 1 artery and 1 vein. The outer and inner perimeter of single artery, double arteries and the vein was 3 8?0 3mm vs 6 2?0 3mm, 2 4?0 2mm vs 4 6?0 2mm and 10 0?0 4mm vs 10 8?0 4mm at empty and flatened state, respectively. The diameter of vein at 20mmHg filling pressure and single and double arteries at 80mmHg was 7 2?0 3mm, 4 8?0 1mm and 3 9?0 8mm, respectively. According to these values, various drainage and perfusion metal tubes were designed and evaluated both in vitro and in vivo. By using these tubes,extracorporeal circulation was established successfully via umbilical artery and vein in a newborn who suffered from cardiac arrest after birth. The results suggest that CPB through umbilical artery and vein is simple, practical and effective.
