Objective To evaluate the effect of multiple-mode analgesia consists of epidural administration of lidocaine,parecoxib intravenously and patient-controlled epidural analgesia (PCEA) on patients after thoracic surgeries. Methods Total 90 patients treated with thoracic surgeries were allocated into 3 groups by random digits table,each with 30 cases. Patients accepted 1% lidocaine 5 ml epidurally 5 min before incision in group A and B,and 5 ml saline as control in group C. When chest closing parecoxib 40 mg were given in group A,and 2 ml saline as control in group B and C. All the patients were given PCEA. Postoperative hemodynamics,dosage of remifentanil and analgetics of PCEA within 48 h, visual analogue scale (VAS) of pain, rescue of pethidine, duration for first pain calling,and satisfactory scores of patients, doctors and nurses were recorded. Results Dosage of remifentanil was lower [(0.72±0.26), (0.84±1.20) μg／(kg·min)], and duration for first pain calling was longer[(35.00±2.78),(12.09±6.27) min] in group A and B than that in group C significantly[(1.80±0.84) μ,g／(kg·min) and (5.95±3.65) min](P<0.05). Analgetics of PCEA with in 48 h in group A was lower than that in group B which was lower than that in group C[(180.40±20.48), (192.54±40.15), (220.26±36.78) ml](P< 0.05). No difference was found on VAS of pain and hemodynamics among three groups when patients were kept immobilized, but VAS of pain in group A and B was lower than that in group C when patients kept moving. Satisfactory scores of patients,doctors and nurses in group A were higher. Conclusion Epidural administration of 1% lidocaine combined with intravenous paiecoxib 40 mg and PCEA an offer satisfactory postoperative analgesia for patients after elective thoracic surgeries.

Objective To compare the effect of three kinds of reverse trendelenburg position angle in block plane of prone position after subarachnoid anesthesia, in order to acquire the conformable reverse trendelenburg position angle of prolapse and hemorrhoids (PPH). Methods Sixty patients having underwent the selective PPH were divided into 10° group, 20° group and 30° group by random digits table method with 20 cases each. Subarachnoid puncture was performed in the L3 - 4 processus spinosus gap, then 0.5%heavy density ropivacaine 2 ml was injected. After anesthesia, the operation bed was adjusted to reverse trendelenburg position 10° (10° group), 20° (20° group) and 30° (30° group). At the same time the patients changed to prone position, and the operation bed was changed to horizontal position before operation. The patients changed to jackknife position 10 min after drug injection of subarachnoid anesthesia. The sensory blockade after drug infusion, circulation function change, anesthetic effect and perioperative adverse reaction were observed. Results There were no statistical differences in operation start time and fixed time of anesthesia plane among 3 groups (P>0.05). The upper bound of sensory nerve block before horizontal position, upper bound of sensory nerve block before jackknife position, highest plane of sensory nerve block in 10° group were significantly higher than those in 20° group and 30° group: T(10.47 ± 0.65) vs. T(12.36 ± 0.72) and T(12.50 ± 0.54), T(10.12 ± 0.56) vs. T(11.82 ± 0.66) and T(11.99 ± 0.72), T(9.53 ± 0.71) vs. T(11.32 ± 0.78) and T(11.54 ± 0.83), and there were statistical differences (P<0.05); but there were no statistical difference between 20° group and 30° group (P>0.05). The systolic blood pressure and diastolic blood pressure levels 15 and 20 min after drug infusion in 10° group were significantly lower than those in 20° group and 30° group, systolic blood pressure:(120.40 ± 7.38) mmHg (1 mmHg=0.133 kPa) vs. (131.82 ± 7.88) and (130.47 ± 7.57) mmHg, (119.55 ± 7.65) mmHg vs. (131.25 ± 9.67) and (130.23 ± 8.69) mmHg, diastolic blood pressure: (63.74 ± 6.54) mmHg vs. (71.36 ± 8.49) and (74.32 ± 7.54) mmHg, (61.59 ± 6.23) mmHg vs. (72.98 ± 7.39) and (73.75 ± 6.34) mmHg, and there were statistical differences (P<0.05);but there were no statistical difference between 20° group and 30° group (P>0.05). No patients′ anesthesia effect was poor in 3 groups, but 4 cases in 30° group were good. Hypotension and tachycardia occurred in 2 cases in 10° group, respectively. Conclusions Immediately prone position after subarachnoid anesthesia can be adjusted by reverse trendelenburg position angle to get the appropriate level of anesthesia, and conformable reverse trendelenburg position angle of PPH is 20°.

AIM To study the effects of poly- N -acetylglucosamine on the metabolism of low density lipoprotein and lipoprotein (a). METHODS Poly- N -acetylglucosamine was injected into the body of hedgehogs viathe armpit vein 2 minutes before the 125 I low density lipoprotein ( 125 I-LDL), 125 I lipoprotein(a) 〔 125 I-Lp(a)〕, 125 I desialylated low density lipoprotein ( 125 I-ds-LDL) or 125 I desialylated lipoprotein(a) 〔 125 I-ds-Lp(a)〕 were injected separatively . The animals were put to death in one hour. The radioactivity in the blood, liver, kidney, spleen, gall and adrenal were measured. RESULTS Absorption of ds-LDL and ds-Lp(a) increased in the liver. Later ds-LDL was reutilized and released into blood, but the majority of ds-Lp(a) was excreted out of the body from liver. It was not eliminated that ds-LDL was metabolized via the LDL receptor for the uptake of ds-LDL also increased in the kidney and the adrenal. It is possible that ds-Lp(a) and the part of ds-LDL may be catabolized via the desialylated lipoprotein-related receptor. Poly- N -acetylglucosamine could increase the absorption of LDL in the liver and the adrenal, meanwhile the concentration of LDL decreased in the blood and the absorption of LDL decreased in the spleen. CONCLUSION Poly- N -acetylglucosamine has the effects of lowering lipids through activating LDL receptor.

Objective To investigate the solubilitization effect of macromolecular paclitaxel with cyclodextrin and mechanism between inclusion complex and drugs. Methods The influence effects on paclitaxel solubility were studied with ?-cyclodextrin (?-CD) and hydroxypropyl-?-cyclodextrin (HP-?-CD) as inclusion carriers.
