AIM: To develop a rat model of insulin resistance and observe the effect of puerarin injection on expression of GSK-3 in insulin resistance rats.METHEDS: 30 Wistar rats were divided into three groups randomly: control group,model group and puerarin group.The model group and puerarin group were given high fat diet(20% surcose,10% ard,(2.5)% chlesterol,1% cholic acid) for 4 weeks.Then the puerarin group was given abdominal injection puerarin 100(mg?kg~(-1)?d~(-1)) for six weeks.At the end of this experiment,we detect GSK-3 protein by western-blot analysis.Then computer image pattern analysis system was used to analyze the expression of GSK-3 in the hepatacyte.RESULTS: Tthe model group showed a hyperglycemia,hyperinsulinism,the ISI decreased and HOMA-IR increased.GSK-3 expression enhanced in the model group,but the expression of GSK-3 in puerarin group decreased compared to the model group.CONCLUSION: Puerarin injection can significantly decreased the expression of GSK-3 and improve insulin resistance.

Objective To evaluate the accuracy of spectral entropy including response entropy(RE)and state entropy(SE)as a new electroencephalographic measure of depth of sedation during general anesthesia.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-55 yr undergoing elective abdominal surgery were studied.Anesthesia Was induced with intravenous propofol,fentanyl and vecuronium.After tracheal intubation anesthesia was maintained with sevoflurane inhalation and intermittent iv boluses of fentanyl and vecuronium.BP,HR,SpO2,spectral entropy(Datex-Ohmeda)and BIS(Aspect Medical)were monitored during anesthesia.Loss of eyelash reflex and unresponsiveness to verbal stimulus and mild prodding and shaking were considered to be signs of loss of consciousness(LOC).The time of regaining consciousness Was defined as the time when patients started responding to verbal commands.RE,SE and BIS were recorded before anesthesia(baseline),10 min before LOC,immediately after LOC,immediately after tracbeal intubation,1 h after skin incision,10 min before regaining consciousness immediately after consciousness was regained and 10 min after extubation.Results There were sisnificant changes in RE,SE and BIS during the transition from consciousness to LOC.The RE,SE and BIS values for LOC were 76,73 and 68 with sensitivity of 94%,95%and 92%and specificity of 92%,94%and 91%respectively.The accuracy of RE.SE and BIS in predicting LOC was 93%,95%and 94%respectively.The RE,SE and BIS values for regaining consciousness were 82,75 and 70 with sensitivity of 95%,95%and 91%and specificity of 93%,96%and 93%respectively.The accuracy in predicting regaining of consciousness was 98%,96%and 97%respectively.Conclusion Entropy index Can accurately monitor level of sedation during general anesthesia.

20 normal males were examined by BIODEX isokinetic test and rehabilitation system,and data collected were used to observe the influence of angle and time on the isokinetic concentric constriction of knee joint. It was found that angle and time, especially angle factor obviously affected the testing results.

Objective To dynamic monitoring the changes of serum cortisol,adrenocorticotropic hormone (ACTH) in children with sepsis and servere sepsis,and to assess it's relationship with clinical features.Methods Thirty children with sepsis were enrolled in this study from Sep 2010 to Jan 2011 in our hospital,and were divided into severe sepsis group (n =10) and sepsis group (n =20).The serum cortisol and ACTH were analysed in acute and recovery period respectively in both two groups,and compared with 10 non-sepsis children as control group.Results In the acute period,the level of serum cortisol in severe sepsis group [ (33.97 ±6.83) μg/ml ] was significantly higher than those in sepsis group [ (26.30 ± 10.43) μg/ml]and control group [ ( 19.06 ± 6.91 ) μg/ml ] ( P ＜ 0.01 ) ; the level of serum ACTH in severe sepsis group [ (25.47 ± 9.41 ) pg/ml ] was significantly higher than those in sepsis group [ ( 15.52 ± 5.85 ) pg/ml ] and control group [ (9.16 ± 3.02 ) pg/ml ] ( P ＜ 0.01 ).Conclusion Stress response exists in the early period of sepsis,and the levels of serum cortisol and ACTH are increased significantly.The levels of serum cortisol and ACTH are positive correlation with the severity of diseases,and they could be used as serious index and a marker for evaluating prognosis in children with sepsis.

Objective To explore the clinical feature and influencing factors of pneumonia in patients with lung cancer,in order to these patients might be timely diagnosed and treated correctly.Methods A series of 1495 cases of pneumonia in patients with lung cancer in recent 10 years were reviewed as their clinical characteristics, pathological cell types, imaging study, bacteriological monitoring, chemotherapy/radiotherapy, antibiotic treatment and prognosis.Results The infection rate of pneumonia in patients with lung cancer was 60.8%, most of them were occurred in patients treated after chemotherapy/radiotherapy, especially in patients being treated after glucocorticoid. The prognosis was poor.Conclusions The clinical situation of pneumonia in patients with lung cancer is not typical. The symptom of respiratory tract is not obvious. CT scan demonstrated obstructive pneumonia and atelectasis. Gram-negative bacteria were the mainly pathogen. The influencing factors are related to the smoking, chronic consumption, obstruction of bronchus, lower resistance after chemotherapy/radiotherapy and the basic diseases. The methods of treatment are also prelimilary discussed.
