Objective To observe the selective regulation of peroxisome proliferator-activated receptors (PPAR) on fatty acid binding protein-4 (FABP4) in human syncytiotrophoblasts.Methods Cultivate normal human syncytiotrophoblast cells,and put in the specific antagonists and agonists of PPAR each subtypes receptors,then observe the different expression of FABP4 mRNA and protein.Results Pretreated the human syncytiotrophoblast cells with the agonists (GW7647,GW0742) and antagonists (GW6471,GSK0660) of PPARα and PPARβ receptors,the expression of the FABP4 was not significantly change (P＞0.05).However pretreated with PPARγ agonists (rosiglitazone,1 × 10-9,1 × 10-8,1 × 10-7 and 1 × 10-6 mol/L),the expression of FABP4 mRNA and protein could be dose dependent-promoted significantly (mRNA:1.27 ±0.12,1.45 ±0.14,1.57±0.14,1.72 ±0.12,protein:1.10 ±0.08,1.37 ±0.09,1.60 ±0.13,1.79 ± 0.14 ; P ＜ 0.05),furthermore,the promotion can be dose dependent-reversed by specific antagonists GW9662 (mRNA:0.92 ± 0.06,0.77 ± 0.06,0.64 ± 0.05,0.55 ± 0.05,protein:0.91 ±0.03,0.78 ±0.06,0.70±0.07,0.55 ±0.06; P ＜ 0.05).Conclusions In normal human syncytiotrophoblast cells,FABP4 is a target factor of PPARγ.PPARγ regulated the expression of FABP4 mRNA and protein selectively.And the regulation will not be influenced by the other two PPAR subtypes.

Objective To investigate the effect of alternating shift on general well-being of nurses,and analyze its relationships with related factors. Methods Alternating shift nurses from general hospi-tals above courty-level in Liaocheng city who were engaged in clinical work were selected by duster sam-pling.Questionnnires were sent out and later gathered. The investigation tools included general well-being schedule(GWB) ,marital quality inventory, social support inventory, Eysenck personality questionnaire were used in survey. Results (1)There was difference in the score of general well-being between nurses with different ages and professional titles(P<0.01). (2)There was significant difference between GWB and oth-er factors such as marital quality,EPQ (psychoticism, neuroticism and introversion and extroversion), so-cial support(P<0.01). (3)Multivariable linear regression which took general well-being as dependent vari-able, the variables which entered the equation were neuroticism, family relationship,support utilization,psychoticism, objective support, introversion and extroversion, marriage satisfaction,arrangement of econ-omy. Conclusions (1)The older, the higher of professional tltles,the stronger general well-being of nurses. (2)Sabjective well-being and marital quality, social support, lying defense were positively corre-lated; neuroticism, psychoticism were negatively correlated. (3)Neuroticism, family relationship,support and utilization, psychoticism, objective Support, introversion and extroversion, marriage satisfaction,ar-rangement of economy can affect general well-being,among which neuroticism had great influence.

Objective For the purpose of exploring the influence exerued by the amount of template DNA on the results of automatic fluerescent detection. Method For the purpose of buiding the optimal amount of template DNA amplified, we have analyzed different amount of template DNA (9947A) by 3100 Genetic Analyzer with the multiplexing Profiler Plus Kit. Results The optimal amounts of template DNA amplified were between 0.31ng and 2. 5ng by using 3100 Genetic Analyzer. Conclusion It will produce the incorrect analytic results if the amounts of template DNA were too high or too low.

ObjectiveTo explore adrenal insufficiency in the preterm infants who had critical lung diseases and the relationship between adrenal insufifciency and long-term or short-term prognosis.Methods The basal cortisol and ACTH of iffty preterm infants enrolled were tested. The peak cortisol at 30 minutes after low dose ACTH stimulation was tested. The adrenal insufifciency was deifned as the concentration of the basal cortisol less than 15 μg/dl or the increment of cortisol concentration after low dose ACTH stimulation less than 9 μg/dl. The pretern infants with adrenal insufifciency were the AI group and others were the adrenal normality, AN group.Results Thirty-one cases were adrenal insufifciency in 50 preterm infants with critical lung disease. The incidence was 62%. The concentrations of the basal and peak cortisol in AI group were lower than those in AN group (P<0.01). The increment of cortisol concentration after low dose ACTH stimulation had not signiifcant difference between two groups. The concentration of ACTH in AI group was lower than that in AN group (P<0.01). The mean arterial blood pressure in AI group was lower than that in AN group (P<0.01). The blood sugar, potassium and sodium had no signiifcant difference between two groups (P>0.05). There was no signiifcant difference in the mortality and the incidence of BPD between two groups (P>0.05).Conclusions The incidence of adrenal insufifciency was high in the preterm infants with critical lung diseases, which may be due to insufifcient production of endogenous ACTH. When the adrenal insufifciency was happened, the blood pressure is relatively low in preterm infants with critical lung diseases, but it was not related to the mortality and the incidence of BPD.

Objective To determine the median effective concentration (EC50) of remifentanil inhibiting responses to tracheal extubation in patients of Uygur nationality.Methods The patients of Uygur nationality,aged 18-60 yr,of ASA physical status Ⅰ or [Ⅱ,scheduled for elective surgery,were enrolled in this study.After the end of surgery,remifentanil was given by target-controlled infusion until tracheal extubation.The initial target plasma concentration (Cp) of remifentanil was 2.0 ng/ml.The response was defined as positive when MAP and/or HR increased by ＞ 15％ of the level at the end of operation and the duration ＞ 15 s during extubation.Each time the target Cp increased/decreased if the cardiovascular response was positive or negative.The ratio between the two successive concentrations was 1.1.The EC50 and 95 ％ confidence interval of remifentanil blunting responses to extubation was calculated by Probit method.Results Twenty-eight patients completed the study.The EC50 and 95 ％ confidence interval of remifentanil required for inhibiting the responses to extubation was 1.75 ng/ml and 1.45-2.01 ng/ml.Conclusion The EC50 of remifentanil inhibiting the responses to tracheal extubation is 1.75 ng/ ml in patients of Uygur nationality.

OBJECTIVE: To investigate the feasibility of utilizing pedicled sternocleidomastoid clavicular periosteocutaneous flap to reconstruct the laryngotracheal defect after tumor resection. METHOD: To review 6 cases of laryngotracheal defect resulting from resction of thyroid papillary carcinoma(4/6) or subglottic laryngeal carcinoma (2/6) (T1~2N1~2M0 , UICC,2002), laryngotracheal stenting was also employed in all cases. Half a year after surgery, the stoma was sutured if no local recurrence took place and safety was proved after tracheal tube had been obstructed for days. The follow-up time lasted from half a year to 3 years. RESULT: Four cases (4/6) were extubated successfully without event, one case could intermittently plug the tracheal tube. One patient couldn't breath with tracheal tube plugging. CONCLUSION To reconstruct the laryngotracheal defect with pedicled sternocleidomastoid clavicular.periosteocutaneous flap after tumor resection is feasible in selected cases and could get satisfactory clinical results either in respiration or phonation.

Objective:To evaluate the effect of repeated intranasal insulin on postoperative delirium (POD) in elderly patients undergoing general anesthesia.Methods:Seventy elderly patients, aged ≥65 yr, with body mass index ≤28 kg/m 2, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, undergoing elective radical gastrectomy for gastric cancer under general anesthesia, were divided into 2 groups ( n=35 each) according to the random number table method: control group (group C) and insulin group (group I). In group C, normal saline 0.5 ml was administered intranasally twice a day from 2 days before surgery until the day of surgery.In group I, insulin 20 U (0.5 ml) was administered intranasally twice a day from 2 days before surgery until the day of surgery.The regional tissue oxygen saturation (rSO 2) was measured after entering the operating room (T 0), at intubation (T 1), at 1, 2 and 3 h after the start of operation (T 2-4), at the end of surgery (T 5) and at extubation (T 6). The insulin allergic reactions, nasal irritation and hypoglycemic reactions were recorded after intranasal administration of insulin or normal saline within 2 days before operation.The blood glucose concentrations were measured at T 0, T 3 and T 5.The occurrence of POD within 3 days after operation was recorded. Results:Compared with group C, the incidence of POD was significantly decreased within 3 days after operation, and the rSO 2 was increased at T 1-6 in group I ( P<0.05). The rSO 2 was significantly higher at T 1-6 than at T 0 in two groups ( P<0.05). There were no significant changes in blood glucose concentrations at T 0, T 3 and T 5 between the two groups ( P>0.05). No insulin allergic reactions, nasal irritation and hypoglycemic reactions occurred in two groups ( P>0.05). Conclusion:Repeated intranasal administration of insulin can increase the rSO 2 during operation and decrease the occurrence of POD in elderly patients undergoing radical gastrectomy for gastric cancer.
