Objective To explore clinical characteristics and the perinatal effects of multiple systems in pre-pregnancy obesity patients with early-onset preeclampsia. Methods A total of 111 cases with early-onset preeclampsia in our Inpatient Obstetric Department were reviewed in this study. According to pre-pregnancy body mass index (BMI), patients were divided into normal before pregnancy group (BMI<28 kg/m2, n=56) and obese before pregnancy group (BMI≥28 kg/m2, n=55) . The body weight, BMI, weight gain during pregnancy, risk factors, clinical features, and clinical features of neonatal index were compared between two groups. The correlation between maternal and neonatal indexes and glucose and lipid indexes were compared. Results Obese before pregnancy was more prone to blood concentration and disorders of lipid metabolism. The serum levels of lipid, glycosylated hemoglobin (HbA1c), hematocrit, platelet and fibrinogen were significantly higher in obese before pregnancy group than than those of normal group. The induced neonatal acidosis and other organ damage, newborn Apgar score, pH, glucose were significantly lower in obese before pregnancy group than those of normal group. The residual alkali (BE), lactic acid (LAC), creatine kinase (CK) and creatine kinase (CKMB) were higher in obese before pregnancy group than those of normal before pregnancy group. Correlation analysis showed that maternal low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), three acyl glycerol (TG) and HbA 1c were negatively correlated with neonatal Apgar score and pH, and which were positively correlated with neonatal LAC and CKMB. Both differences were significant (P<0.05 or P<0.01). Conclusion The dyslipidaemia in early onset preeclampsia in obesity patients before pregnancy is closely related with maternal and perinatal outcomes.

Objective To evaluate the effects of doxofyline on intraoperative pulmonary function in patients receiving double lumen endotracheal intubation for one-lung ventilation. Methods Fifty patients who underwent elective pulmonary lo-bectomy under general anesthesia using double lumen endotracheal intubation were randomly divided into two groups ( n=25 each):control group (group C) and doxofyline group (group D).Doxofyline (4 mg?kg-1) was injected intravenously after double lumen endotracheal intubation in group D,while equal volume of 0.9% sodium chloride was intravenously given in group C.Total intravenous anesthesia with target controlled infusion was performed during the operation.Two milliliter blood samples were taken from the radial artery for blood gas analysis immediately before administration ( t0 ) ,at 30 min ( t1 ) ,60 min ( t2 ) after one-lung ventilation and at the moment of two-lung ventilation after chest closing ( t3 ) . The PaCO2 , PaO2 , peak airway pressure (Ppeak),airway plateau pressure (Pplat),airway resistance (Raw) and lung compliance (Compl) were recorded at t0-3. Results The Ppeak,Pplat and Raw were significantly decreased and the Compl and PaO2 significantly increased at t1-t3 in group D when com-pared with those in group C (P<0.05).The Ppeak,Pplat and Raw were significantly increased and Compl and PaO2 significantly de-creased at t3 as compared with those at t0 in group C ( P<0.05) . Conclusion Doxofyline can improve intraoperative pulmonary function in patients who undergo double lumen endotracheal intubation for one-lung ventilation.

Objective To evaluate the feasibility of using lumbar plexus block for unilateral extremity artificial vascular graft between femoral artery and deep femoral artery in elderly patients.Methods Forty ASA physical status Ⅱ or Ⅲ patients,aged 67-81 yr,weighing 47-65 kg,scheduled for extremity artificial vascular graft between femoral artery and deep femoral artery,were randomly divided into 2 groups (n =20 each) using a random number table:spinal anesthesia group (group S) and lumbar plexus block group (group L).In group S,0.5 ％ hyperbaric ropivacaine 3 ml was injected into the subarachnoid space.In group L,lumbar plexus block was performed with 30 ml of 0.5 ％ ropivacaine under the guidance of a nerve stimulator.The onset time and duration of sensory block,anesthetic efficacy,and requirement for ephedrine and volume of fluid infused during operation,and development of lumbar plexus block-related adverse events were recorded.Results Compared with group S,the onset time and duration of sensory block were significantly prolonged,the requirement for ephedrine and volume of fluid infused during operation were decreased,and no significant change was found in anesthetic efficacy in group L.No lumbar plexus block-related adverse events developed in group L.Conclusion Lumbar plexus block can be used for unilateral extremity artificial vascular graft between femoral artery and deep femoral artery in elderly patients.

Objective To investigate the changes of serum thyroxine level in obstructive sleep apnea-hy-popnea syndrome(OSAHS) patients and to assess the role of serum thyroxine in the development of OSAHS. Meth-ods Polysomnography was used to examine the patients with OSAHS and fasting plasma serum thyroxine level were higher in obese OSAHS patients than in obese controls[ (43.56±3.48)cm vs (38.33±3.08)cm,t =4. 258,P < 0.05 ], in non-obese OSAHS patients than in non-obese control group [ (40.50±1.05 )cm vs (36.17±3.13 )cm, t = 3. 146 ,P < 0.05 ] . The levels of FT3 was (6.35±3.15 ) pmol/L in obese OSAHS patients and ( 4.08±2.37 ) pmol/L in control subjects ( t = 2.203 ,P < 0.05 ). That was ( 3.42±0.57 ) pmol/L in non-obese OSAHS patients related with AHI and microarousal index (r = 0. 500, P < 0.05;r = 0.561, P < 0.05 ), and FT4 was also positively with neck circumference( t = 0.489, P < 0.05 ), TSH level was negatively correlated with neck circumference ( t = - 0.500, P < 0.05 ) and was positively correlated with the percentage of body fat ( r = 0.498, P < 0.05 ). Conclu-sions The FT3 levels are significantly higher in the OSAHS patients than that in control subjects, though all FT3 lev-els are normal, suggesting that there are possibility to have abnormal metabolism. At the same time, FT3 level is posi-tively correlated with neck circumference ,suggesting that the OSAHS patients' higher neck circumference is correla-ted with thyroxine.

Objective To explore the effect of humidification of oxygen delivered by nasal cannula on the respiratory symptoms. Method A total of 540 patients receiving low-to-mid flow oxygen therapy (<4L/min) by nasal cannula for more than 12 hours were assigned to receive humidified (n=235) or dry (n=305)oxygen. While 226 patients receiving a low-to-mid flow oxygen therapy for more than 24 hours received humidified or dry oxygen respectively. The patients' respiratory symptoms were observed and recorded. Results Dryness over naso-pharyngeal region was the only symptom reported by patients in this study. There was no significant difference on the rate of dryness over naso-pharyngeal region between patients receiving humidified oxygen and patients receiving dry oxygen (P>0.05) either in the same patients when receiving dry and humidified oxygen (P>0.05). Conclusion Routine humidification is not necessary in low-to-mid flow oxygen therapy by nasal cannula.

Objective To evaluate the effects of dexmedetomidine on responses to tourniquet in patients undergoing lower extremity surgery with peripheral nerve block.Methods Eighty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 22-63 yr,weighing 47-81 kg,scheduled for elective foot surgery under ultrasound-guided popliteal sciatic nerve block combined with saphenous nerve block,were divided into 2 groups (n =40 each) using a random number table method:control group (group C) and dexmedetomidine group (group D).Dexmedetomidine was intravenously infused for 10 min in a dose of 1 μg/kg in group D,and the equal volume of normal saline was given instead in group C.Blood samples were taken from the internal jugular vein before using the tourniquet (T0) and at 30 and 60 min after releasing the tourniquet (T1-2) for determination of the levels of c-reactive protein (CRP),tumor necrosis factor-alpha (TNF-α),methane dicarboxylic aldehyde (MDA) and superoxide dismutase (SOD) in plasma.The time to responses to tourniquet,tourniquet tolerance time and tourniquet tolerance period were recorded.The occurrence of hypotension,bradycardia and nausea and vomiting was also recorded.Results Compared with the baseline at T0,the concentrations of plasma CRP,TNF-α and MDA were significantly increased and the activity of plasma SOD was decreased at T1,2 in the two groups (P＜0.05).Compared with group C,the concentrations of plasma CRP,TNF-α and MDA were significantly decreased and the activity of plasma SOD was increased at T1,2,the time to responses to tourniquet,tourniquet tolerance time and tourniquet tolerance period were prolonged,and the incidence of bradycardia was increased in group D (P＜0.05).Conclusion Dexmedetomidine can reduce responses to tourniquet in patients undergoing lower extremity surgery with peripheral nerve block.

Objective To observe the clinical efficacy of Sanyinjiao acupoint sticking with Gushen Yutai Tie on threatened abortion. Methods A total of 216 women diagnosed with threatened abortion were randomly assigned to trial group (108 cases) and control group (108 cases). Both groups were treated with TCM syndrome differentiation treatment and progesterone soft capsule, and the trial group was treated with Gushen Yutai Tie acupoint sticking at Sanyinjiao (SP6) additionally. One treatment course was five days, and both groups were treated for three courses. Vaginal bleeding and lower abdominal pain, lumbar pain, nausea and vomiting were observed, pulsatility index (PI) and resistance index (RI) of the uterine artery were detected after treatment. Results The total effective rate in the trial group was 97.22% (105/108), which was significantly higher than that of 90.74% (98/108) in the control group (P<0.05). Symptom scores in the trial group were also significantly higher than those in the control group (P<0.01). PI and RI in the ineffective (pregnancy failure) group were much lower than that of effective (threatened abortions with normal outcome) group (P<0.01). Conclusion The treatment that Gushen Yutai Tie acupoint sticking at Sanyinjiao combined with TCM syndrome differentiation and progesterone soft capsule had a better effect to improve pregnancy success rate in threatened abortion. PI and RI in uterine artery could be used to evaluate the outcome of pregnancy.
