Objective To investigate the effects of acute hypervolemic hemodilution (AHH) with hydroxyethyl starch (HES) 130/0.4 on intestinal mucosal barrier in a rat model of sepsis.Methods Thirty healthy New Zealand rabbits of both sexes weighing 2.0-3.0 kg were randomly divided into 3 groups (n=10 each):group I sham operation; group II sepsis and group III AHH+sepsis.Sepsis was produced by modified colon ascendens stent peritonitis(CASP).At 4 h after CASP group III meceived HES 130/0.4 20 ml/kg iv at a rate of 20 ml/min.The MAP and HR were monitored and recorded at 4 h (before AHH) and 5,6,7,8 h after CASP.Blood samples were taken from carotid artery and superior mesenterie vein (SMV) at 4 h and 8 h after CASP for blood gas analysis and determination of plasma D-lactate concentration and intestinal oxygen extraction ratio.The rabbits were sacrificed at 8 h after CASP and a segment of ileum of 3 cm in length,5 cm from ileocecal valve,was removed for determination of wet/dry ileum weight ratio and microscopic examination.The degree of damage to intestinal mucous membrane was scored according to Chiu score (0=normal,5=severe damage).Results Sepsis-induced hypotension and metabolic acidosis,increased plasma D-lactate concentration,decreased intestinal oxygen extraction ratio,increased wet/dry ileum weight ratio and Chiu score in group II as compared with group I.AHH with HES 130/0.4 20 ml/kg significantly attenuated the scpsis-induced changes in group III.Conclusion AHH with HES 130/0.4 can attenuate damage to intestinal mucosal barrier produced by sepsis.

Objective To investigate the influence of support and intervention technique with multi-dimensions on uncertainty in illness for cancer children′s parents. Methods With convenience sampling method, a total of 74 cases of hematological malignant and solid tumor patients′ parents in Hematology and Tumor Centre of Children′s Hospital of Fudan University were selected. There were 35 cases in the intervention group, which were given multi-dimension-support and intervention technique for 8 weeks as well as regular chemotherapy and nursing care. There were 39 cases in the control group, who were only given regular chemotherapy and nursing care. The level of uncertainty in illness in both groups were evaluated after 8 weeks of the base-line investigation. Results The scores of uncertainty in illness reduced over time in both groups (F=95.402,P<0.01). After 8 weeks, the scores of the intervention group were lower than those of the control group (F=24.079,P < 0.01). Conclusions The all-round, multi-dimension and real-time techniques of support and intervention could decrease the level of uncertainty in illness for cancer children′s parents.

0. 05 ). For detection of pancreatic duct dilation and lymph node metastasis, EUS was better than CT ( P=0.039,P=0.004). The accuracy of EUS in determing peripancreatic fat infiltration and organic invasion was correlated with tumor size (P=0.015,P=0.022) , pancreatic duct dilation was correlated with the location of tumors ( P

Objective To study the 3D CRT plan for hepatic tumors. Methods The 3DCRT plan of 50 cases of primary or metastasis hepatic cancer were designed according to the request of the doctors for CTV and the restricted receiving dose of the peripheral normal sensitive organs. The best plan was chosen referring the dose-volume histogram. Results By using ICRU dose reference point (the central point of tumor) as the dose 100 % and 80 % ~ 90 % dose line can be surrounded above 90 % of the PTV(planning tumor volume). The degree of 90 % dose line surrounding PTV was related to the scope of target area and its location. Conclusion The focus in different localization can be treated with different design when devise the treatment plan of the hepatic tumors. The reaction to radiotherapy was directly influenced by the volume of dosage of radiation to the normal hepatic tissues, and it also had great influence to the choice of prescription dose and the dose division style.

Breast cancer is one of the most common malignant tumors in women,the trend of young women with breast cancer in China is obvious.Some young patients in the diagnosis of breast cancer are unmarried,so they have a certain degree of expectation of the protection of ovarian function and reali-zation of the right.In the treatment of breast cancer,the doctors should understand the effects to gonadal function.In chemotherapy,for some patients with ovarian function inhibitors have a protective effect to o-varian fuction.At present,there are some methods to protect the reproductive function,such as cryopreser-vation of oocytes,cryopreservation of embryos and preservation of ovarian tissues and so on.But thoses methods for the protection of ovarian function and reproductive function are not yet perfect.

Objective To investigate the effects of 3 different delivery methods on maternal and fetal complications during labor and determine better mode of delivery. Methods Sixty pregnant women with ASA class Ⅰ or Ⅱ were randomly divided into three groups with 20 cases each: the cesarean section group (group Ⅰ), the pain relief group (group Ⅱ) and normal delivery group (group Ⅲ). In group Ⅰ and Ⅱ, an epidural catheter was placed through L_(2-3) interval. 0.5% ropivacaine was injected via the epidural catheter for continuous epidural anesthesia in group Ⅰ. After a loading dose of 8-10 mL 0.125% ropivacaine+2 μg/mL fentany, the patient-controlled epidural analgesia (PCEA) during labor was started with bolus 5 mL, lockout interval 20 min and back ground infusion rate 6-8 mL/h in group Ⅱ. The level of block was controlled below T_(10). BP, HR and RR were continuously monitored during labor. Blood samples were taken from umbilical vein at delivery for blood gas analysis and determination of lactate concentration. Neonates were assessed by Apgar score and neurological and adaptive capacity score (NACS). Maternal postoperative complications were recorded. Results There was no statistical differences in plasma pH, PCO_2, PO_2, SO_2, Apgar score and NACS among 3 groups. The umbilical vein blood lactate concentration was significantly increased in group Ⅱ and Ⅲ compared to the group Ⅰ, while blood lactate concentration in group Ⅱ was lower than that in the group Ⅲ (P<0.05). Base excess (BE) was significantly higher in group Ⅲ than in group Ⅰ. Compared with group Ⅱ and Ⅲ, maternal postoperative complications such as urinary retention, postpartum hemorrhage and so on were increased significantly in group Ⅰ (P<0.05). PCEA provided satisfactory effect in group Ⅱ. Conclusions Epidural labor analgesia with 0.125% ropivacaine+2 μg/mL fentany can provide comparative and effective analgesia for pain relief during labor without adverse effects on the mothers and fetuses and may reduce the postoperative complications. It is a safer and more effective technique in pain relief during labor.

Objective To compare the time-course of relaxant effect of rocuronium between patients with ocular and generalized myasthenia gravis (MG).Methods Twenty-seven ASA physical status I or Ⅱ patients with MG of both sexes,aged 12-64 yr,with body mass index of 17-26 kg/m2,scheduled for elective extended thymectomy,were divided into 2 groups according to Osserman stage:ocular group (group O,n =10) and generalized group (group G,n =17).Anesthesia was induced with iv injection of fentanyl 2 μg/kg,midazolam 0.05 mg/kg,and propofol 1.5 mg/kg.All patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with iv infusion of propofol 4-8 mg· kg-1 · h-1 and remifentanil 0.2 μg· kg-1 · min-1.Twitch tension was monitored in the adductor pollicis muscle by train-of-four stimulation of the ulnar nerve (intensity 60 mA,interval 12 s,frequency 2 Hz,wave length 0.2 ms).Rocuronium 0.6 mg/kg was injected intravenously after calibration.Mean arterial pressure (MAP),HR,heart rate variability (HRV) and low frequency and high frequency (LF/HF) ratio was recorded.The onset time of muscle relaxation,time for T1 to recover to 25％,time for T1 to recover to 50％ and recovery index were recorded.Results Compared with the baseline value,there were no significant changes in MAP,HR,HRV,LF/HF ratio at all time points in the two groups (P ＞ 0.05).Compared with group O,there was no significant change in the onset time of muscle relaxation,and the time for T1 to recover to 25％,time for T1 to recover to 50％ and recovery index were significantly prolonged in group G (P ＜ 0.05).Conclusion The duration of rocuronium-induced neuromuscular block is significantly longer in patients with generalized MG than those with ocular MG,while the onset time is comparable between the two groups.

Objective To compare the effects of different modes of delivery on arterial oxygen saturation in the fetus.Methods One hundred and twenty ASA Ⅰ or Ⅱ parturients aged 22-32 yr with a single fetus at full term lying in normal headdown position were divided into 3 groups according to the modes of delivery (n =40 each):group cesarean section (group CS) ; group labor analgesia (group LA) and group spontaneous labor (group SL).In group CS cesarean section was performed under epidural anesthesia with 0.5％ ropivacaine.Epidural catheter was placed at L2,3 interspace in groups CS and LA.In group LA labor analgesia was started from the first stage and maintained until complete cervical dilatation.The patients received epidural PCA (PCEA) with O.125 ％ropivacaine plus fentanyl 2 μg/ml.PCEA setting was as follows:a loading dose of 8-10 ml; demand bolus 5 ml;20 min lockout; background infusion 6-10 ml/h.Blood samples were taken from umbilical artery at delivery for blood gas analysis and determination of serum concentrations of lactate,β-endorphin (β-EP) and neuropeptide Y (NP-Y).Apgar score and neurological and adaptive capacity score (NACS) were recorded.Results There was no significant difference in Apgar score,NACS and NP-Y and β-EP concentrations in umbilical arterial blood among the 3 groups.The lactate concentration and the absolute value of BE were significantly higher while pH was lower in group SL than in groups CS and LA.PO2 was significantly higher while PCO2 was lower in group LA than in groups SL and CS,and the lactate concentration and absolute value of BE were significantly lower while pH was higher in group LA than in group SL.Conclusion The 3 modes of delivery have significant effects on arterial oxygenation in fetus but have no clinical significance.

Objective To investigate the correlation and significance of cyclooxygenase-2 (COX-2)and the breast cancer resistance protein (BCRP) expressions in non-Hodgkin lymphoma(NHL). Methods Ten patients with reactive lymph nodes (RLN) were considered as a control group. Compared with β-actin as internal control, the BCRP mRNA expressions of 61 NHL samples and 10 lymph tissues in control group were detected by semi-quantitative revere transcription polymerase chain reaction (RT-PCR) assay, while the expressions of COX-2 protein of the above specimens were detected by SP immunohistochemistry. Results The positive rates of COX-2 and BCRP in NHL were 50.8 %(31/61) and 45.8 % (28/61), respectively , and were higher than those in the control group (P ＜0.05). The expression of COX-2 was statistically positive correlated to that of BCRP (X2 =8.795, r=0.355, P＜0.05). The expressions of COX-2 and BCRP were not correlated to clinical and pathological factors, such as age, sex, IPI, LDH, β2-microglobulin level and Ann Arbor stage, however, the expression of BCRP was statistically correlated to chemotherapy efficacy.Conclusion BCRP may be involved in multi-drug resistance (MDR) of NHL, so it may contribute to the assessment of chemotherapy and prediction of NHL. Since there is a strong correlation between COX-2 expression and MDR in NHL, the application of COX-2 inhibitors may enhance sensitivity of chemotherapy.
