Objective To evaluate the value of Disposcope-guided the left-sided double-lumen tube (DLT) intubation.Methods Fifty ASA physical status Ⅰ or Ⅱ patients,aged 47-69 yr,without difficult airway,scheduled for elective thoracic surgery,were randomly divided into 2 groups (n =25 each) using a random number table:Disposcope (group D) and Macintosh direct laryngoscope (group M).Anesthesia was induced with iv injection of midazolam,propofol,sufentanil and rocuronium.Before induction (baseline,T1),before intubation (T2),immediately after successful intubation (T3),and at 1 and 3 min after intubation (T4-5),systolic blood pressure (SBP),mean airway pressure (MAP) and heart rate (HR) were recorded,and rate-pressure (SBP) product (RPP) was calculated.Arterial blood samples were obtained at T1-5 for measurement of plasma epinephrine (E),norepinephrine (NE),and dopamine (DOPA) concentrations.The success rate of DLT intubation at first attempt,total success rate of DLT intubation,intubation time,and development of sore throat within 24 h after surgery were recorded.Results Compared with group M,the intubation time was significantly shortened,the success rate of DLT intubation at first attempt was increased,the incidence of sore throat was decreased,and the levels of MAP,HR,RPP,E,NE and DOPA were decreased at T3-5 in D group (P < 0.05).Compared with the baseline value at T1,the levels of MAP,HR,RPP,E,NE and DOPA were decreased at T3-5 in M group (P < 0.05),and no significant change was found in D group (P > 0.05).Conclusion Disposcope-guided left-sided DLT intubation provides significant clinical value.

Objective To investigate the effect of indomethacin on prevention of heterotopic ossification (HO)after operative treatment of acetabular fractures.Methods Fifty patients with acetabular fractures received in our department operative treatment through Kocher-langenbeck(K-L)approach and oral administration of in- domethacin afer operation from February 2001 to August 2003.Forty-eight of them were successfully followed up for incidence of HO and their clinical functions were assessed.The results were compared with those of 40 patients who had been treated with the same operative procedures but without oral administration of indomethacin in our depart- ment from March 1993 to May 1998.The patients who could not tolerate the drug were not included.Results The follow-ups averaged 22.8 months(range,6 to 39 months).HO occurred in eight cases.The incidence of HO was 16.7%(8/48).According to Brooker evaluation of HO,five cases were rated as degreeⅠ,three as degreeⅡ, and none as degreeⅢorⅣ.The incidence of severe HO was 0.In the control group,the incidence of HO was 35.0%(14/40)and the incidence of severe HO was 10.0%(4/40).The differences were statistically significant (P<0.05).Conclusion Oral administration of indomethacin after operative treatment of acetabular fractures can inhibit HO.

Objective To investigate the effects of aquaporin4 (AQP4) on the brain injury after cerebral ischemic reperfusion and to search the new method that can prevent and cure the injury. Methods Locally injection of naked DNA ( pcNDA3.1/Zeo), which carries AQP4 gene and reporter gene green fluorescent protein(GFP), in the brain was performed 12 h before ischemic challenge to up-regulate the AQP4 expression. The expressed level of AQP4, the infarction size and neurological deficit scores were estimated in three groups. Results (1) Exogenous AQP4 expression in the brain did not affect the healthy rat neurological deficit score; (2) Rat neurological deficit scores were 7.9?0.7, and 7.1?0.9 respectively in 12 h and 24 h after reperfusion in AQP4 injected group, which were lower than that in plasmid control group when both groups were challenged with reperfusion after ischemia; (3) Expression of AQP4 in the brain was higher in AQP4 injected group than plasmid control group and control group in early stage after reperfusion; (4) Expression of exogenous AQP4 in the brain increased the cortex and striatum infarction size 24 h after reperfusion, which were (261.0?18.2) mm 3 and (21.9?1.9) mm 3, respectively, in AQP4 injected group more than plasmid control group. Conclusions (1) Increased local AQP4 expression in brain does not affect neurological function in the healthy rat; (2) Pre-expression of AQP4 increase infarction size and neuro-functional injury; (3) Modification of AQP4 activity and regulation of AQP4 expression level would be the new strategy for the prevention of cerebral edema and the reduction of cerebral injury after stroke.

The incidence of iron deficiency anemia and its therapeutic measures were studied in 559 children (aged 6 months to 3 years old) in Shijiazhuang city, Hebei province. The results showed that the incidence of iron deficiency anemia(IDA) was 53.85% and iron deficiency was 48.11%. Most of IDA occurred before 2 years of age and mild in character.No differences in hair Fe and Zn content were noted between anemic and unanemic children, but hair Cu was lower significantly in anemic children than in unanemics (Pyears old), group D under combined measures of A and B, group E as control. According to Hb re-estimated 2 months after treatment, A,B,C group had the same better therapeutic result than group E, but no combined effect was seen in group D.

In order to construct a prokaryotic expression vector of human receptor syt II N-fragment and to express recombinant MBP-Syt fusion protein in E.coli and to purify and identify its activity. According to codon preference of E.coli, a DNA fragment encoding human syt II N-fragment was synthesized, and then cloned into prokaryotic vector pMAL-c2x for sequencing. Then the recombinant plasmid pMAL-Syt was introduced into E.coli ER2566 by transformation for expression and the obtained engineered bacteria were induced by IPTG. The fusion protein was purified by amylose resin affinity chromatography and identified by SDS-PAGE and Western blot. The binding activity of the protein was determined by ELISA. It is concluded that MBP-Syt protein is of good binding activity.
