Objective To investigate effects of early administration of high-dose rosuvastatin(40 mg) on coronary microvascular function and short-term outcome in patients treated with primary percutaneous coronary intervention (PCI) for acute myocardial infarction(AMI). Methods Ninety-four consequent AMI patients treated with primary PCI were divided into rosuvastatin group (50 patients) and control group (44 group). The infarct-related artery flow of epicardium was classified in compliance with the TIMI criteria. Myocardial and microvascular perfusion was assessed using the TMPG. The incidence of the MACE and the cytotoxicity and hepatotoxicity of rosuvastatin was respectively recorded in 30 d follow-up period. Results Either patients in the rosuvastatin group or in the control group showed better TMPG immediately after PCI (P<0.05), compared with that before treatment. However, the post-PCI TMPG of the rosuvastatin group was obviously much better than that of control group (P<0.05). Compared with that in control group, the 30-day composite MACE rate was lower in rosuvastatin group and in the TMPG 3 patients of rosuvastatin group:12.0%(6/50) vs. 34.1%(15/44), P<0.05;11.1%(3/27) vs. 42.9%(6/14). There was no cytotoxicity and hepatotoxicity in two groups. Conclusions Early administration of high-dose rosuvastatin (40 mg) can improve coronary microvascular function and short-term outcome in patients treated with primary PCI for AMI, and it is efficient and safety.

Objective To research the degree of sensory disturbance(about algaesthesis and thermesthesia) in patients with cerebral infarction(CI),diabetes mellitus(DM) and CI combined DM(CD).Methods The threshold values of rhigosis,heat sensation,cryalgesia and thermalgesia were detected by quantitative sensory testing(QST) in the patients with CI(CI group),DM(DM group),CD(CD group).Each group had 30 cases.The results were compared with normal control group(NC group).Results Compared with NC group,acral thermic sense and cryalgesia in CI group and CD group were declined obviously(all P

To investigate the effects of preoperative intravascular embolization on treatment of intracranial giant arteriovenous malformations (AVMs), 27 patients with intracranial giant AVMs were successfully treated from August, 1997 to April 1998 every patient was treated with preoperative intravascular embolization. Compared with single surgical resection, it was found that surgical resection after intravenous embolization can greatly reduce the intraoperative hemorrhage, diminish postoperative mortality and morbidity, and prevent normal perfusion pressure breakthrough (NPPB) significantly. The present study suggested that combination of surgical resection and intravascular embolization was an effect way in the treatment of giant cerebral AVMs.

Objective To compare the effect of sacroiliac anterior papilionaceous plate (SAPP) and the traditional reconstruction plate for the treatment of sacroiliac joint disruption.Methods 11 consecutive patients with sacroiliac joint disruption associated with pelvic fracture enrolled in our hospital.Detailed physical examination,X-rays,CT and FAST were performed before surgery.11 patients underwent SAPP fixation.Of the 11 patients,there were 5 males and 6 females.Their average age was 39.6 years.12 patients enrolled in last year as control group underwent reconstruction plate.There were 7 males and 5 females in this group.Their average age was 39.1 years.Operation time,blood loss,placing time of SAPP were recorded.X-ray films were performed after surgery to evaluate reduction condition by Matta criteria.X-ray films and Majeed outcome were performed in follow up.Results According to Tile classification,there were 13 Type B and 10 Type C.For SAPP group,operation time was (100.9±32.1) min,blood loss (998.8±365.7)ml,Placing time of SAPP was (6.6±3.2) min.For control group,operation time was (110.8±29.6) min,blood loss was (136.0±279.3) ml,placing time of reconstruction plate was (15.4±1.1) min.According to Matta criteria,8 cases were rated as excellent,11 as good,3 as fair,and 1 as poor.Lumbosacral nerve injury occurred in 1 case,lateral femoral cutaneous nerve injury in 7,and massive blood loss in 2 cases.No posterior infection occurred.Compared with control group,SAPP group experienced shorter placing time,and less blood loss in type B pelvic fracture.Conclusion As a new instrument,SAPP could be well applied in the treatment of sacroiliac disruption.Compared with reconstructed plate,SAPP obviously shortens placing time and facilitated placing procedure,and does not increase blood loss,neurological risk and infection rate and does not need different incision and reduction method.

Objective To evaluate the effect of the noxious stimulation factor on γ-aminobutyric acid (GABA) distribution in dog spinal cord during propofol anesthesia.Methods Sixteen healthy mongrel dogs of both sexes,aged 12-18 months,weighing 10-12 kg,were randomly divided into 2 groups (n =8 each):noxious stimulation group (S group) and control group (C group).Anesthesia was induced with propofol 7 mg/kg.The animals were mechanically ventilated after tracheal intubation.Right femoral artery was cannulated for mean arterial pressure (MAP) and pulse rate monitoring.Anesthesia was maintained with propofol infusion at a constant rate of 70 mg· kg-1 · h-1.5 ％ formalin 300 μl was subcutaneously injected into the central region of tails in group S,while the equal volume of normal saline was injected instead of formalin in group C.MAP and pulse rate were recorded before injection of formalin or normal saline (T1) and after injection of formalin or normal saline (T2).The dogs were scarified by decapitation at 50 min of continuous propofol infusion and cervical 2-3 segments of the spinal cord were removed for determination of GABA level in different regions of the spinal cord (frontal horn,posterior horn,intermediate zone,frontal funiculus,posterior funiculus and lateral funiculus) by HPLC.Results MAP and pulse rate were significantly higher at T2 than at T1 in S group (P ＜ 0.05).There were no significant differences in GABA level among the different regions of the spinal cord in C group (P ＞ 0.05).Compared with C group,GABA level in the frontal horn and posterior horn was significantly increased (P ＜ 0.05),and no significant change was found in the other regions of the spinal cord in S group (P ＞ 0.05).Conclusion The noxious stimulation factor can induce an increase in GABA level in the frontal horn and posterior horn of dog spinal cord during propofol anesthesia.

Objective To evaluate the effect of early continuous renal replacement therapy(CRRT)on patients with acute kidney injury(AKI)induced by severe sepsis. Methods A prospective study was conducted. 160 patients with AKI induced by severe sepsis admitted to intensive care unit(ICU)of Qingyuan People's Hospital between October 2009 and June 2013 were enrolled. According to the starting time of CRRT,the patients were randomly divided into two groups:an earl y treatment group and a regular treatment group(each,80 cases). All patients were treated in accordance with the principle of the cluster of severe sepsis. In early treatment group,the patents began to receive CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment over 6 hours,but the curative effect was not ideal. In the regular treatment group,the patients began to apply CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment persistently over 24 hours or difficultly corrected acidosis or heart failure developed. The changes in urine output,creatinine,saturation of blood oxygen,and albumin,and 28-day survival rate,length of ICU stay,time of organ support were measured and compared between the two groups to evaluate the therapeutic significance of the early CRRT. Results The mean length of ICU stay(day:6.5±1.7 vs. 8.2±1.6),length of organ support(day:5.3±1.8 vs. 6.0±1.4),the recovery time of urine amount(day:3.4±0.9 vs. 4.8±0.5)in early treatment group were significantly shorter than those in regular treatment group(all P<0.01);recovery ratio of urine in 1 week in early treatment group was significantly higher than that in regular treatment group(46.2%vs. 28.8%,P<0.05). The creatinine recovery ratio in 1 week in early treatment group was lower than that in regular treatment group(55.0%vs 78.8%),but there was no statistically significant difference(P>0.05). Early treatment group and regular treatment groups of creatinine recovery time were similar(day:5.1±1.3 vs. 5.2±1.2). 28-day survival rate in early treatment group was higher than that in regular treatment group(41.2%vs. 35.0%),but there was no statistically significant difference(P>0.05). Conclusion It is found that there is no evidence to suggest that early CRRT may improve the prognosis of the patients with AKI induced by severe sepsis,but it may be in favor of shortening the time of urine recovery,length of stay in ICU,length of organ support and length of dialysis.
