Health staff of single obesity in the hospital were as control. Results:During sleep, the enengy-metabolism was increased significantly in OSA patients. After treatment by CPAP, it was decreased (P

Objective To investigate the relationship of intraoperative cerebral oxygen saturation(rSO_2 )monitored with near-infrared cerebral oximeter (INNOS 5100) and postoperative cognitive dysfunction in patientsoperated upon under isoflurane or sevoflurane anesthesia and to determine the critical rSO_2 value below whichpostoperative cognitive dysfunction may occur.Methods Sixty ASA Ⅰ- Ⅱ patients of both sexes aged 62-80 yr,weighing58-77 kg schedules for elective abdominal surgery or surgery on the low limb were divided into threegroups according to their levels of education: group Ⅰthe illierate and uneducated (n = 20); group Ⅱ primaryschool education (6yr education (n = 20). Each group was furtherdivided into isoflurane and sevoflurane subgroups (n = 10 in each subgroup). The patients were unpremedicated.Anesthesia was induced with intravenous atropine 0. 3mg, propofol 1 .0-1. 5 mg?kg~(-1), fentanyl 2-3?g?kg~(-1) andvecuronium o. 1-0.2 mg?kg~(-1) and maintained with isoflurane or sevoflurane inhalation (0.9-1. 1 MAC )supplemented with intermittent i.v. boluses of fentanyl and recorded before anesthesia (baseline), after O_2inhalation(T_1), after induction of anesthesia(T_2), after skin incision (T_3), during operation (T_4)and at the end ofsurgery (T_5). Mini-Mental State Examination (MMSE) was performed before anesthesia and 1,4, 8, 12 and 24 hafter surgery. BP, HR, ECG, SpO_2, P_(ET) CO_2 and end-tidal concentration of inhalational anesthetics werecontinuously monitored during anesthesia. Results In all three groups rSO_2 was significantly lower during operation(T_4) and at the end of surgery (T_5 ) than baseline (T_0 ) (P

Eighty-seven patients with hyperthyroidism were enrolled in a retrospective study,and 35.6％ of them also suffered from pulmonary hypertension(PH).Advanced age and systolic or diastolic dysfunction of left heart were risk factors in the mechanism of PH associated with hyperthyroidism (all P＜0.05).However,autoimmune disorder was found as a non-related factor in the mechanism of PH(P＞0.05).

Objective:To prepare and optimize sorafenib-Eudragit RS nanoparticles( S-E üPs)and investigate the physicochemi-cal properties. Methods:S-E üPs were prepared by a solvent-nonsolvent method. Single factor experiments were used to research the effect of solvent,stabilizer type,carrier ratio and the proportions of water phase and organic phase on the physicochemical properties of S-E üPs. S-E üPs were evaluated by the particle size,zeta potential and morphology,and the in vitro drug release of S-E üPs was studied using dialysis technology. Results:The mean size was(86. 72 ± 3. 71)nm,the PDI and zeta potential was(0. 20 ± 0. 032)and (36. 6 ± 0. 3)mV,respectively,S-E üPs showed spherical shape with uniform distribution. The drug release in vitro was accorded with a Weibull equation. Conclusion:The solvent-nonsolvent method is appropriate for the preparation of S-E üPs. The nanoparticles have small particle size,uniform distribution,regular morphology and significant sustained-release property.

Objective To investigate the relationship between intraoperative cerebral oxygen saturation (rSO2) and postoperative cognitive dysfunction with near-infrared cerebral oximeter (INVOS 5100) in patients operated under inhalational combined intravenous anesthesia, and to determine the critical rSO2 value below which postoperative cognitive dysfunction may occur. Methods Sixty ASAⅠ-Ⅱ patients of both sexes were selected, aged 62-80yr, weighed 58-77kg, scheduled for elective abdominal surgery or surgery on the low limb. All the patients were divided into three groups according to their educational background: in group Ⅰ were the illiterate and uneducated patients (n=20);group Ⅱ the primarily educated patients (<6yr education) (n=20), and group Ⅱ the well educated patients (>6yr education) (n=20). Each group was further divided into isoflurane and sevoflurane subgroups (n=10 in each subgroup). All patients received no pre-medication. Anesthesia was induced with intravenous atropine 0.3mg, propofol 1.0-1.5mg kg-1, fentanyl 2-3μg*kg-1 and vecuronium 0.1-0.2mg*kg-1, and maintained with isoflurane or sevoflurane inhalation(0.9-1.1 MAC) supplemented with intermittent i.v. boluses of fentanyl, and recorded after entering room (baseline) (T0), after O2 inhalation (T1), after induction of anesthesia (T2), after skin incision (T3), during operation (T4), the end of surgery (T5), and awaking (T6). Mini-Mental State Examination (MMSE) was performed before anesthesia and 1, 4, 8, 12 and 24h after surgery. BP, HR, ECG, SpO2, PETCO2 and end-tidal concentration of inhalational anesthetics were continuously monitored during anesthesia. Results In all three groups rSO2 was significantly lower during operation (T4) and at the end of surgery (T5) than baseline (T0) (P<0.05). In all patients the MMSE scores at 1h after operation were significantly lower than the baseline value (P<0.05). The MMES scores in all patients significantly declined within 1-4h after surgery, and the cognitive function recovered at 4h after surgery in 85% patients. The critical values of rSO2 below which postoperative cognition dysfunction may occur were: 45 (group Ⅰ), 47 (group Ⅱ) and 49 (group Ⅲ) for isoflurane anesthesia subgroups;47 (group Ⅰ), 48 (group Ⅱ) and 50 (group Ⅲ) for sevoflurane subgroups. Conclusion The perioperative rSO2 should be maintained up to above 50% to reduce the incidence of postoperative cognitive dysfunction under inhalational combined intravenous anesthesia.

Objective To evaluate the effects of different anesthetic methods on myocardial function after the CABG operation and compare the hemodynamic variables under the propofol total intravenous anesthesia with high dosages fentanyl anesthesia. Methods 12 patients (ASA Ⅲ) undergoing selective CABG operation under CPB were randomly divided into two groups (with 6 in each): Group Ⅰ (large dosages of fentanyle anesthesia), and Group Ⅱ (propofol total intravenous anesthesia). The hemodynamic parameters were recorded after induction of anesthesia, after sternotomy, after CPB, and after closure of thoracostomy. Results There were no significant differences of MBP, HR, SVRI, CI, LVEF, and A/E, Tei index between the two groups. Conclusion The method of propofol total intravenous anesthesia (TIVA) was safe, effective and praticable for the CABG operations under CPB.

72 sera of highly sensitized antibody patients were detected by 35 samples of undonor lymphocytes before and after the dithothreitol (DTT) treating.The results showed that 72 sera reacted completely to B lymphocytes in both 4℃ and 37℃,but incompletely to T lymphocytes.After removal of the transplant kidney due to rejection,the sera antibody levels of T or B lymphocytes were higher than those of the patients'sera after blood transfusion or pregnancy.The serum T or B antibody levels of pregnancy were the lowest.In DTT-treated sera of highly sensitized patients,the antibodies were mixed types of IgG and IgM.

Objective To investigate the effects of propofol and inhalation anesthetics on the implicit memory under general anesthesia and determine the critical value of auditory evoked potential index (AEI) at which implicit memory no longer exists. Methods Sixty ASA I-II patients of both sexes scheduled for elective abdominal surgery or surgery on lower limb were enrolled in the study. They averaged (41.25?9.25) years and (63.8?9.57) kg. Patients with psychoneural or memory disorders were excluded. The patients were randomly divided into five groups of 12 patients in each group: isoflurane, sevoflurane, desflurane, propofol and control group. Each inhalation anesthetic group was further divided into two subgroups based on their end-tidal concentration: 0.8 or 1 .0 MAC. Propofol group was divided into two groups based on the infusion rate: 8 mg.kg. h-1 or 10mg.kg.h-1 . In control group operation was performed under epidural anesthesia. The patients were unpremedicated. Anesthesia was induced with propofot 1 .5-2.0 mg.kg and vecuronium 0. 　-0.2mg.kg-1, and maintained with inhalation anesthetic or propofol infusion supplemented with intermittent boluses of fentanyl and vecuronium. AEI was continuously monitored and recorded before anesthesia (T0), when the patient was sleepy (T1 ) and did not respond to verbal command (T2 ), after intubation (T3), after skin incision (T4), when peritoneum was being closed (or 30 min before the surgery) ( T5 ) and during emergence from anesthesia ( T6 ) . Eight hours after surgery muddy identified hearing rate was determined. Hemodynamic parameters were continuously monitored during operation. Results There was significant difference in AEI between the two subgroups before and after induction (P
