Objective To summarize anesthetic management for 56 patients undergoing off-pump coronary artery bypass grafting (OPCABG). Methods Recorded and analyzed the hemodynamie changes of 56 patients undergoing OPCABG including heart rate (HR),rate-pressure product (RPP), mean arterial pressure(MAP), mean pulmonary artery pressure(MPAP), central venous pressure (CVP), cardiac output (CO) and mixed venous oxygen saturation when left anterior descending (LAD), right coronary artery (RCA), diagonal (DiAG) and left circumflex coronary artery (LCX) was anastmosed. Results The patients undergoing OPCABG had hemodynamic fluctuation during vascular anastomosis, mainly showing MAP and CO decreased, CVP increased. The change was especially significant when the LCX or RCX was anastmosed. The based value, when LAD and RCA anastmosed of MAP were (82.0±11.7) mm Hg(1 mm Hg = 0.133 kPa), (60.1±11.5) mm Hg and (58.4±12.1) mm Hg, CO were (4.2±1.2) L/min, (3.1±0.7) L/min and (3.2±0.6) L/min, CVP were (5.6±2.6) cm H2O (1 cm H2O=0.098 kPa), (9.6±4.4) cm H2O and (9.2±3.6) cm H2O. Conclusion The hemodynamie changes during OPCABG,especially in LCX and RCA anastmesed are transient and well tolerated under suitable anesthetic management.

Objective To explore influence of norm-setting three-stage rehabilitation training on hemiplegic stroke patients with movement and cognitive dysfunction. Methods A prospective randomized controlled study and stepwise linear regression analysis was carried out to investigate the early variation factors, which affected the integrated functional recovery of stroke patients. According to variation factors we established our norm-setting three-stage rehabilitation training program. 200 patients were randomly selected, according to the cerebral infarction and cerebral hemorrhage classification, and then randomly divided into the rehabilitation group and the control group with 100 patients in each group. All patients accepted general neurology routine nursing. The rehabilitation group was given an extra norm-setting three-stage rehabilitation training. The improvement of motor and cognitive function were observed. Results The early variation factors of integrated functional outcome were treatment programs, CNFD score, age, diabetes, SFMA score, smoking and the intensity of labor within six months since stroke onset. Movement and cognitive function of the rehabilitation group significantly improved than the control group as well as upon admission on the first, 3rd and 6th months since stroke onset. Conclusions The norm-setting three-stage rehabilitation training obviously promotes the improvement of motor and cognitive function at all stages.

Objective To evaluate the effect of standardized training and management of prenatal ultrasound screening on birth defects. Methods According to the degree of standardized training and management of prenatal ultrasound screening, the period from March 2004 to December 2009 were divided into three different management stages. Detection rate was applied to describe the prenatal ultrasound screening of 5199 birth defects cases delivered during the three different management stages. Accuracy rate was used to describe the ultrasonographic diagnosis made by staffs in 2009. SPSS 11.5 software was used to analyze the information of 707 staffs participated in the training and assessment activities from October 2007 to September 2009. Related factors of prenatal ultrasound operating skills of staffs were analyzed by comparing the distributing discrepancy of the different variables between qualified and unqualified group with Chi-square test. Results The detection rate of prenatal ultrasonographic screening on birth defects increased with the improvement of training and assessment methods, which was 32. 43% from March 2004 to September 2005,44.81% from October 2005 to September 2007 and 60. 71% from October 2007 to December 2009respectively. In 2009, 187 doctors were tested on abnormal ultrasound photographs identification. The accurate rates were 80. 0% for gastroschisis, 78. 8% for cleft clip, 75.8% for omphalocele, 71.8%for neural tube defects, 50. 0% for severe congenital heart diseases, 31.0% for acromicria, which were in similar sequence as the diagnostic rate identified by prenatal ultrasound in 2009. Among the staffs attending the prenatal ultrasound screening assessment, more had education background at least university level (52.8% vs 47.2%), more performed ≥50 ultrasound screenings per month (50. 5%vs 49.5 % ), more had been working on obstetric ultrasound over 3 yrs (52.5 % vs 47.5 %) and more had been trained in higher level of hospitals focused on prenatal diagnosis (64.7% vs 35.3%) in the qualified group than in the unqualified group. Conclusions Standardized training and management of prenatal ultrasonographic screening could effectively improve the diagnosis rate of birth defects.The quality of prenatal ultrasound screening is related to the staff's education background and whether they are engaged in the position.

OBJECTIVETo investigate the quality of life of cleft lip and/or palate children's parents and discuss the factors to provide the oretical basis for improving the quality of life of these parents and promoting the healthy growth of children with cleft lip and/or palate.

METHODSA total of 115 parents whose children had cleft lip and/or palate surgery treatment were selected as the experiment group, and another 198 parents (with healthy children having a similar age with those in the experiment group) as the control group. The experiment group was divided into three subgroups according to different types of cleft lip and/or palate: cleft Lip (CL), cleft palate (CP), cleft lip and palate (CLP). The experiment group and the control group were both divided into four subgroups according to age: 0-1, 1-3, 3-6 years old, and more than 6 years old. The experiment group and the control group were both divided into three subgroups according to education: junior middle school and the following, high school and technical secondary school, junior college degree or above. The GQOLI-74 scale was selected to assess the experiment group and the control group. SPSS 16.0 software was used to analyze data.

RESULTS1) The experiment group had no significant difference with the control group in terms of the overall score and the scores of various children ages. 2) The scores of every item had no significant difference in CL, CP, CLP subgroup (P > 0.05). 3) The quality of life scores and scores of psychological function dimension and social function dimension of parents with 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P<0.05). The scores of social function dimension of parents with 0-1, 1-3, 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P < 0.05). The other items had no significant difference. 4) The scores of material life dimension and social function dimension of parents with junior college degree or above were higher than those of parents with junior middle school degree and the following (P < 0.05). The scores of social function dimension of parents with high school and technical secondary school degree were higher than those of parents with junior middle school degree and the following (P < 0.05).

CONCLUSIONNo difference was observed in the quality of life between cleft lip and/or palate children's parents and normal group. The parents with the low age children with cleft lip and/or palate and low-levels of education need more help and support to improve quality of life.

Objective To evaluate the effect of dexmedetomidine on acute lung injury induced by scalds in rats.Methods Seventy-five male Sprague-Dawley rats,weighing 200-220 g,were randomly divided into 5 groups (n =15 each) using a random number table:control group (group C),scald group (group S),dexmedetomidine group (group D),α-bungarotoxin (α-BGT) group,and dexmedetomidine+ α-BGT group (group D+α-BGT).About 30％ of the total body surface was shaved and then exposed to 98 ℃ water for 12 s in S,D,α-BGT and D+α-BGT groups.The back of rats was exposed to 37 ℃ water for 12 s in group C.Rats were resuscitated with lactated Ringer's solution injected intraperitoneally according to Parkland formula within 24 h after establishment of the model.In D,α-BGT,and D+α-BGT groups,dexrnedetomidine 40 μg/kg,α7 nicotinic acetylcholine receptor antagonist α-BGT 1 μg/kg,and α-BGT 1 μg/kg plus dexmedetomidine 40 μg/kg were injected intraperitoneally,respectively,at 15 min before establishnent of the model.At 24 h after establishment of the model,the rats were sacrificed,and lungs were removed for examination of the pathological changes and for determination of myeloperoxidase (MPO) activity,in terleukin-1beta (IL-1β),tumor necrosis factor-alpha (TNF-α),and IL-6 contents (by enzyme-linked immunosorbent assay),and nucleoprotein factor kappa B (NF-κB) (by Western blot).The lung water content [(wet weight-dry weight)÷wet weight× 100％] was calculated.Results Compared with group C,the lung water content,MPO activities,and contents of IL-1β,TNF-α and IL-6 were significantly increased,and the expression of NF-κB was up-regulated in S,α-BGT and D groups (P＜0.05).Compared with group S,the lung water content,MPO activities,and contents of IL-1β,TNF-α and IL-6 were significantly decreased,and the expression of NF-κB was down-regulated in D and D+α-BGT groups (P＜0.05),and no significant change was found in the parameters mentioned above (P＞0.05),and the pathological changes were significantly attenuated in group α-BGT.Compared with group D,the lung water content,MPO activities,and contents of IL-1β,TNF-α and IL-6 were significantly increased,the expression of NF-κB was up-regulated (P＜0.05),and the pathological changes were aggravated in group D + α-BGT.Conclusion Dexmedetomidine can mitigate scalds-induced acute lung injury in rats.

Objective To investigate the effect of ultrasound-guided paravertebral nerve block on stress reaction in patients undergoing esophageal resection. Methods Eighty patients scheduled to do the operation of esophageal resection were randomly divided into two groups with 40 cases in each group. The patients in group A were given the general anesthesia combined with ultrasound-guided paravertebral block, and the patients in group B were given the general anesthesia only. Both of two groups received postoperative patient controlled intravenous analgesia (PCIA). The amount of propofol and remifen-tanil used were recorded. The data of blood pressure, heart rate (HR) and pulseoxygen saturation (SpO2) before anesthesia (T1), before induction (T2), after intubation (T3), in 2 h of surgery (T4), after surgery (T5), 1 h after surgery (T6), 8 h after surgery (T7), 24 h after surgery (T8), 48 h after surgery (T9)were recorded. The analgesic effect was measured by VAS scores and Ramsay sedation scores were also recorded at T6-T10. The levels of blood glucose, epinephrine (E), norcpincphrinc (NE) and dopamine (DA) were also detected at T1, T4, T5, T9. Results The amount of propofol and remifentanil used in group A were lower than those in group B: (960.0 ± 216.9) mg vs. (1 242.5 ± 200.2) mg, (1.5 ± 0.4) mg vs. (2.3 ± 0.4) mg, P<0.05. The patients in two groups successfully completed surgery, and intraoperative vital signs was stable. The quiet and active VAS scores at T6-T9 in group A were significantly lower than those in group B (P<0.05). The Ramsay sedation scores at each time point in two groups had no significant differences (P>0.05). The levels of blood glucose and NE at T9 were significantly higher than those at T1, T4 or T5 of same group, P<0.05.The level of E at T4 and T5 was significantly lower than that at T1 and T9 of same group, P<0.05. The level of DA at T9 was significantly higher than that at T1, T4 and T5 in group B (P<0.05). The levels of blood glucose, NE, E and DA at T9 in group B were significantly higher than those in group A (P<0.05). Conclusions General anesthesia combined with ultrasound-guided paravertebral nerve block could offer favorable anaesthesia effect. It could decrease stress reaction and anesthetics requirements in patients undergoing esophageal resection.

Objective To evaluate the role of α7 nicotinic acetylcholine receptor (α7nAChR) in reduction of endotoxin-induced acute lung injury (ALI) by limb ischemic preconditioning in mice.Methods Eighty healthy male C57BL/6 mice,aged 8-10 weeks,weighing 22-26 g,were randomly divided into 5 groups (n =16 each) using a random number table:control group (group C),ALI group,limb ischemic preconditioning group (group P),α-bungarotoxin (α-BGT) group,and limb ischemic preconditioning +α-BGT group (group P+α-BGT).Normal saline 100 μl was intratracheally instilled in group C.In group ALI,lipopolysaccharide 5 mg/kg was intratracheally instilled (in normal saline) to establish the model of endotoxin-induced ALI.In group P,the mice were subjected to 6 cycles of 5-min ischemia of the right hindlimb followed by 5-min reperfusion,and then the model of ALI was established.In group α-BGT,α-BGT 1 μg/kg was injected intraperitoneally before establishment of the model.In group P+α-BGT,limb ischemic preconditioning was performed,α-BGT 1 μg/kg was then injected intraperitoneally,and the model of ALI was established.At 24 h after LPS instillation,6 mice were selected from each group and sacrificed,and lungs were removed for microscopic examination and for determination of wet and dry lung weight,myeloperoxidase (MPO) activities,contents of interleukin-lbeta (IL-1β),tumor necrosis factoralpha (TNF-α) and IL-6,and expression of α7nAChR and high mobility group box-1 (HMGB1) in lung tissues.The lung water content was calculated.The survival of the left 10 mice in each group was observed at 7 days after establishment of the model,and the survival rate was calculated.Results Compared with group C,the lung water content,MPO activities,contents of IL-1β,TNF-α and IL-6,and HMGB1 expression were significantly increased,α7nAChR expression was significantly down-regulated,and the 7-day survival rate was significantly decreased in group ALI(P＜0.05).Compared with group ALI,the lung water content,MPO activities,contents of IL-1β,TNF-α and IL-6,and HMGB1 expression were significantly decreased,α7nAChR expression was significantly up-regulated,and the 7-day survival rate was significantly increased in group P (P＜0.05).Compared with group P,the lung water content,MPO activities,contents of IL-1β,TNF-α and IL-6,and HMGB1 expression were significantly increased,α7nAChR expression was significantly down-regulated,and the 7-day survival rate was significantly decreased in group P+α-BGT (P＜0.05).Conclusion The mechanism by which limb ischemic preconditioning inhibits inflammatory responses and reduces endotoxin-induced ALI is related to activation of α7nAChR in mice.
