Objective To investigate the discriminatory power of Auditory Evoked Potential and Bispectral Index devices on consciousness or consciousless state of patients during intraoperative wake-up test and recovery from scoliosis surgery with sevoflurane-remifentanil anesthesia.Methods Thirty ASA Class I or II adolescents undergoing scoliosis surgery under sevoflurane-remifentanil anesthesia were randomly divided into three groups: standard clinical practice (control), AEP-guided, and BIS-guided. After induction of general anesthesia remifentanil was infused at the rate of 0.3 ?g/(kg?min). At the beginning of wake-up test, the circuit was opened while the vaporizer was turned off , and the rate of remifentanil infusion was decreased to 0.05 ?g/(kg?min). Anesthesia was started again as soon as the patients had movements to command. The AAI, BIS, and end-tidal sevoflurane concentration at the time of before induction (T0), circuit opened(T1), spontaneously breathing recovered (T2), patients movement to command (T3), tracheal extubation (T4) and emergence from anesthesia (T5), as well as the time of spontaneously breathing recovered, patients movement to command during wake-up test, tracheal extubation and emergence from anesthesia were recorded.Results Comparing with control group, AAI and BIS increased at T1 both in AEP-guided and BIS-guided group (P

Objective To evaluate the right ventricular function using volumetric pulmonary artery catheter (VPAC) in patients undergoing off-pump coronary artery bypass grafting (CABG) .Methods Thirty-two patients (18 males, 14 females) aged 45-63 yrs weighing 58-74 kg undergoing CABG were studied. Their cardiac functions were graded according to NYHA classification as Ⅰ or Ⅱ. Radial artery was cannulated before induction of anesthesia for BP monitoring. Anesthesia was induced with midazolam 0.03-0.05 mg?kg-1, fentanyl 10-15 ?g?kg-1 and pipecuronium 0.1-0.15 mg?kg-1 and maintained with 1.0-1.5% isoflurane. The probe (7 MHz) of the transesophageal echocardiography (TEE, Sonos 2500, HP) was placed in esophagus after tracheal intubation for measurement of both right and left ventricular end-diastolic, end-systolic volume and ejection fraction (LVEDV, LVESV, LVEF, RVEDV, RVESV, RVEF). VPAC (type 774HF75, Edwards Life Science Co) was placed via right internal jugular vein for measurement of RVEDV, RVESV and RVEF. 6% HAES 10 ml?kg-1 was infused over 10 min. The cardiovascular parameters mentioned above were measured before and immediately after 6% HAES infusion using both TEE and VPAC, and compared.Results The RVEDV and RVESV (measured by TEE and VPAC) and LVEDV, LVESV (by TEE) were significantly increased after HAES infusion as compared with the baseline values (P

Objective To study the changes in cerebral cortex glutamate (G) content induced by isoflurane inhalation alone or combined with 2-amino-5-phosphonovalerate (AP5),a NMDA receptor competitive antagonist.Methods Six adult male SD rats were anesthetized with isoflurane. Dialysis probe (internal diameter=0.05mm) which was connected to a micro-infusion pump filled with artifical cerebrospinal fluid(ACSF) was inserted into cerebral cortex. The dialysate was collected for determination of G concentration. After the baseline MAC for isoflurane was measured, the study was carried out in 4 groups based on the concentration of isoflurane inhalation: group Ⅰ:1%; group Ⅱ:1MAC; group Ⅲ:2% and group Ⅳ: the effect of AP5 on isoflurane MAC value. In group Ⅳ AP5 was continuously infused at a rate of 100 ?g?kg -1?h -1 via the vein in the tail and the MAC for isoflurane was measured again. G concentration of dialysate was measured and EEG and SEP were monitored in every group.Results G concentration of cerebral cortex dialysate was decreasing with increasing concentration of isoflurane from group Ⅰ to group Ⅲ. Concentration of isoflurane was negatively correlated with cerebral G content (r=-0.839,P

Objective To investigate the clinical efficacy ofHejie Fenxiao Decoction on damp-heat patients with acute kidney injury (AKI).Methods Totally 68 patients were divided into the control group and the treatment group according to the patients’ willings. Both groups were given treatment, such as elimination of the incentives and symptomatic treatment. Besides, patients of the treatment group acceptedHejie Fenxiao Decoction for 30 days. The changes of renal function indexes, such as serum creatinine (SCr), blood urine nitrogen (BUN), uric acid (UA), albumin (ALB) and integral of TCM syndrome, were observed, and recovery ratio and clinical endpoints were compared.Results SCr and eGFR of both group were improved on day 14 (P<0.05). After treatment, the renal function recovery ratio and renal replacement ratio in the two groups showed obvious differences (P<0.05);although survival rate of treatment group was higher than control group, it showed no statistical significance (P>0.05);clinical endpoints analysis of the two groups showed statistical significance (P<0.05). The difference of integrals of TCM syndrome between the two groups showed statistical significance (P<0.05) on day 14.ConclusionHejie Fenxiao Decoction combined with basic regular Western medicine can better improve the clinical symptom, recover the renal function, and decrease the rate of renal replacement and death of AKI damp-heat patients.

Objective To investigate the role of fibroblast growth factor-23 (FGF23) in secondary hyperparathyroidism (SHPT). Methods (1)Serum FGF23 and intact parathyroid hormone (iPTH)from 38 maintenance hemodialysis (MHD) patients were measured by ELISA and chemiluminescence enzyme immunoassay respectively.(2) Parathyroid cells from six SHPT patients underwent parathyroidectomy with forearm autotrlansplantation were cultured for 24 h,then were induced by 0.1 mg/L FGF23.The supernatant was collected at 0.6,12,24 and 48 h respectively. The concentration of iPTH was measured by chemiluminescence enzyme immunoassay. (3)Protein expression of Klotho,FGFR1,FGFR3,GATA-3 and PCNA in parathyroid tissue from 33 SHPT eases and 3 healthy people were detected by immunohistochemistry SP and PV methods respectively. Positive cell rate and absorbance were calculated. Results (1) Serum FGF23 [(3901.85±2618.11) ng/L] was positively correlated with serum iPTH [(460.00±489.77) ng/L] in MHD patients. (2) 0.1 mg/L FGF23 suppressed iPTH secretion of parathyroid cells only at 24 h time point in vitro (P<0.05). (3) Expression of GATA-3, FGFR3, Klotho and PCNA was significantly increased and FGFRl was signiticantly decreased in parathyroid tissue of SHPT-patients as compared to healthy people. (4) Positive cell rate of GATA-3 was positively correlated with iPTH (r~2=0.1901, P=0.0425) and PCNA (r~2=0.2584, P=0.0025). Klotho was positively correlated with FGFRI and FGFR3 (r~2=0.2046, P=0.0082;r~2=0.2833, P=0.0014). PCNA was negatively correlated with FGFR1 (r~2=0.1292, P=0.0399) and positively correlated with FGFR3 (r~2=0.1226, P=0.0457). FGFR1 was negatively correlated with serum phosphate (r~2=0.2329, P=0.0044) and positively correlated with serum calcium (r~2=0.1422, P=0.0305). Conclusions FGF23 level is positively correlated with iPTH level in MHD patients. FGF23 can inhibit iPTH secretion of parathyroid cells in a weak and short way, which may be associated with the proliferation of GATA-3 positive cells and parathyroid cells, the up-regulation of FGFR3 and the down-regulation of FGFR1 expression.
