Objective To investigate the effect of Gardiner bacteria infection on preterm delivery and changes of endocrine hor-mone levels.Methods Application of Gardiner bacteria fluorescent marker detection kit in 120 cases of suspected Gardiner bacteria infection pregnant women with immunofluorescence assay,and the levels of serum follicle stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2),progesterone (P)were measured at the same time,90 cases of non maternal Gardiner bacteria infec-tion were enrolled as control.Results After the treatment,98 cases of pregnant women with Gardiner bacteria infection should ex-perienced premature delivery (24-37 week),accounted for 81.67%,compared with the normal pregnant women were statistically significant (P <0.05);and 22 cases of Gardiner bacteria infection pregnant women after treatment no premature birth,accounted for 18.33%,and to all pregnant women infected Gardiner bacteria and experiencing preterm delivery and the control group levels of endocrine hormone were determined,compared the results of FSH,LH,found no significant differences(P >0.05),E2 increased,P decreased,changed significantly (P <0.05 ).Conclusion The probability of premature delivery in women infected with Gardiner bacteria is significantly higher than that of normal pregnant women,at the same time the secretion of hormone changes,so dealing with pre pregnancy and early pregnancy should carry owt Gardiner bacteria examination.

Objective To evaluate the effects of dexmedetomidine on the cerebral oxygen metabolism in elderly patients undergoing general anesthesia.Methods Sixty ASA physical status Ⅰ or Ⅱ patients,aged 60-87 yr,scheduled for elective abdominal surgery under general anesthesia,were randomly divided into 2 groups (n =25 each) using a random number table:control group (group C) and dexmedetomidine group (group D).Anesthesia was induced with iv injection of midazolam,fentanyl,atracurium and propofol.The patients were tracheally intubated and mechanically ventilated.In group D,dexmedetomidine 1.0μg/kg was infused intravenously over 20 min before induction of anesthesia,while the equal volume of normal saline was given in group C.Before induction of anesthesia,at 0 and 10 min after tracheal intubation and at the end of operation (T0-3),blood samples were taken from the radial artery and jugular bulb for blood gas analysis.Arteriovenous blood O2 content difference (DajvO2) and cerebral O2 extraction rate (CERO2) were calculated at the same time.The development of emergence agitation and postoperative delirium within 48 h after surgery were recorded.Resets Compared with the baseline values at T0,the Da-jvO2 and CERO2 were significantly decreased at T1-3 in the two groups (P ＜ 0.05).Compared with group C,the Da-jvO2 and CERO2 were significandy decreased at T2-3,and the incidence of emergence agitation and postoperative delirium within 48 h after surgery was decreased in group D (P ＜ 0.05).Conclusion Dexmedetomidine can improve the cerebral oxygen metabolism and reduce the development of postoperative delirium in elderly patients undergoing general anesthesia.

Objective To evaluate the effects of dexmedetomidine-propofol-fentanyl combined anesthesia on somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) in patients undergoing cervical spine surgery. Methods Thirty-six patients undergoing cervical spine surgery were randomly divided into 2 groups (n = 18 each): propofol-fentanyl combined anesthesia group (group C) and dexmedetomidine-propofol-fentanyl combined anesthesia group (group D). Anesthesia was induced with TCI of propofol and iv injection of fentanyl.After the consciousness disappeared, a laryngeal mask airway was placed and the patients were ventilated. In group D, dexmedetomidine 0.5 μg/kg was injected over 10 min after the consciousness disappeared, followed by an infusion at a rate of 0.5 μg·kg-1 ·h-1 until the end of surgery. In group C, the equal volume of normal saline was administered instead of dexmedetomidine. SEPs (P15-N20) amplitudes and latency were measured and recorded before dexmedetomidine administration and at 10 min of dexmedetomidine infusion. The no-elicitation of MEPs was recorded. Results Compared with group C, there was no significant difference in P15-N20 amplitudes and latency in group D. The no-elicitation rate of MEPs in two groups was 0. Conclusion Dexmedetomidine-propofol-fentanyl combined anesthesia does not affect SEPs and MEPs in patients undergoing cervical spine surgery.

Objective To analyze regional left ventricular systolic function before and after percutaneous translumial coronary angioplasty(PTCA),quantitative tissue velocity imaging(QTVI)was used tO detect wall motion of left ventricule.Methods 20 patients with isolated left anterior descending coronary artery(LAD)stenosis(≥70%)and 16 normal control subjects were included in this study.QTVI was performed one day before PTCA+stent,a week and a month after successful PTCA+stent.Peak systolic myocardial velocity(Vs)were measured with QTVI at different wall segments(basal and medial segments).Results Before PTCA+stent,Vs of all segments assigned by LAD were significantly lower than those of corresponding segments in normal subjects(P＜0.01).After PTCA+stent,the above segments showed a significant improvement of Vs in a week and a month(P＜0.01).Conclusion QTVI can quantitively detect changes of myocardiac motion and real-time quantify regional left ventricular systolic function before and after PTCA.

Objective To investigate the effect of preoperative acute hypervolemic hemodilution with 6% hydroxyethyl starch 130/0.4(HES130/0.4)and polygeline on hemodynamic response and variance regularity of hemodynamic response in open-and close-thoracic cavity in undergoing thoracotomy patients. Methods Sixty patients undergoing thoracotomy,ASA physical status ⅠorⅡ,aged 20~65 yeansold,weighing 45~70kg,were randomly divided three group:HES130/0.4 group ( group A,n=20) ,Polygeline group ( group B,n=20) and Ringer's solution group (group C,n=20).They were respectively infused 20ml/ (kg?h) with HES130/0.4,polygeline and Ringer's solution in one hour before infuseing followed Ringer's 10ml/ (kg?h). The Blood Pressure (BP) and heart rate (HR) were recorded.RPP was calculated before induction(baseline),5min before and 10 min after open thoracic cavity,5min before and 10min after close thoracic cavity. And central venous pressure (CVP) was measured at immediately after deep venous puncture ,5min before and 10min after open thoracic cavity,5min before and 10min after close thoracic cavity. Results The changes of hemodynamics in Ringer's solution group in operation were obvious as compared with baseline before operation.HES130/0.4 and polygeline were relatively stable.Two groups had no significant difference.The CVP of HES130/0.4 and polygeline groups increased obviously before and after open thoracic cavity,but the blood pressure was relatively stable.Only systolic blood pressure increased obviously as compared with Ringer's solution group at 5min before open thoracic cavity. At 10min after open thoracic cavity,HR and CVP in three groups increased obviously as compared with 5 min before open thoracic cavity.At 5 min before close thoracic cavity,blood pressure and CVP in three groups decreased obviously as compared with 10 min after open thoracic cavity. Conclusion The preoperative acute hypervolemic hemodilution with HES 130/ 0.4 and polygeline in undergoing thoracotomy patients can keep hemodynamics more stable and improve tolerance of patients to withstand hypovolemics.

Objective To discuss the clinical effect of Sky bone expander percutaneous ky-pbeplasty (Sky-PKP) in treatment of old osteoperotic vertebral compression fractures. Methods The study involved 27 patients (27 vertebrae) with old osteoporotic vertebral compression fractures treated by Sky-PKP from March 2005 to June 2007. Normotopia, lateral and dynamia radiographs, CT scanning and MRI were performed preoperatively to verify fluid collection in the vertebral body, vacuum phenomenon and open-close phenomenon. Visual analog scale (VAS), Oswestry disability index (ODI), anterior body height, middle line body height, posterior body height and kyphotic angle changes were measured on a lateral radiograph before and after treatment. Results All patients were followed up for mean 6.2 months, which showed no severe complications. VAS score was decresed from preoperative 7.8 to postop-erative 3.1 and ODI from 65% to 37%. However, The anterior vertebral height and middle line vertebral height were recovered for 4.6 nun and 5.7 mm respectively compared with preoperation. Correction of ky-photic angle was mean 5.6°postoperatively. There was no sitatistical changes in regard to posterior body height before and after operation. Conclusions Sky-PKP is a reasonable procedure for treatment of old osteoporotic vertebral compression fractures under strict control of indications, especially with vacuum phenomenon, open-close phenomenon and fluid collection. While high degree of difficulty in puncturation results in insignificant correction of kyphotic angle and body height.
