Methods Totally 100 cases with laparoscopic cholecystectomy were divided into two groups:Dexmedetormidine group and Propofol control group (n=50 for each group) according to the different anesthetic methods.The hemodynamic change,stress reaction and hepatic/renal function were measured and analyzed. Results Heart rate [(85.7±13.4)times /min vs.(62.7±9.9) times/min; (81.3±14.9) times/min vs.(60.3±8.8)times/min,t=2.296,2.714,P=0.045,0.022] and mean artery pressure(MAP )[(86.3±11.9)mm Hg vs.(66.5+11.7) mm Hg; (88.6±15.6) mm Hg vs.(68.7± 12.3) mm Hg,t=2.653,2.240,P=0.024,0.049] immediately at trachea cannula and 1 min after trachea cannula were significantly increased in Propofol control group as compared with Dexmedetomidine group.In contrast to Propofol control group,epinephrine[(680.1±112.3) pmol/L vs.(576.1±83.1)pmol/L; (705.4±127.6)pmol/L vs.648.8±105.3) pmol/L,(689.6±123.4) pmol/L vs.(628.2±94.3) pmol/L,t=2.628,2.242,2.224,P=0.019,0.039,0.040],norepinephrine[(3953.6±514.6) pmol/L vs.(3695.1±196.2) pmol/L; (3967.2=514.9) pmol/L vs.(4367.1±565.7) pmol/L; (4095.8±415.1) pmol/L vs.(3813.4 ± 513.7) pmol/L, t =2.454, 2.500, 2.255, P =0.032, 0.030,0.045] and hydrocortisone [(796.6±198.7) nmol/L vs.(698.7±176.3) nmol/L; (835.5+217.2) nmol/L vs.(783.7±201.9) nmol/L; (822.4±203.3) nmol/L vs.(720.6±188.1) nmol/L,t=2.334,2.167,2.189,P=0.033,0.044,0.043] immediately at trachea cannula,1 min and 5 min after trachea cannula were decreased in Dexmedetomidine group.There were not significantly differences in hepatic/renal function between the two groups (P＞ 0.05). Conclusions Dexmedetomidine is safe and effective for laparoscopic cholecystectomy in view of more stable hemodynamics,less stress reaction,and non influence on hepatic/renal function.

Objective To investigate the significance of preoperative and postoperative enteral nutrition support in gastric cancer patients with nutritional risk.Methods The clinical data of 72 gastric cancer patients with nutritional risk admitted in our department were analyzed.All the patients were randomly allocated into two groups.36 patients in the control group received only intravenous nutrition postoperatively (PN group).36 patients in the treatment group received enteral nutrition support from the fifth day before operation to eighth day after operation (EN group).The body weight,total protein,albumin,transferrin and prealbumin were measured on the fifth day before operation,the operation morning,the first day and the eighth day after operation.Results On the operation morning,the transferrin and prealbumin of the EN group were higher than those in PN group significantly(P ＜0.05).In the eighth day after operation.the treatment group patients showed significant increase in the body weight,total protein,albumin,transferrin and prealbumin compared with those in the control group(P ＜ 0.05).On the operation morning,the transferrin and prealbmnin of EN group were increased significantly than on the fifth day before operation(P ＜ 0.01).Conclusion The preoperative and postoperative enteral nutritional support can improve the nutritlonal condition in the gastric cancer patients with nutritional risk.The preoperative enteral nutritional support can improve the patients' nutritlonal condition and reserves before operation,and reduce adverse reaction of enteral nutrition.

Objective To investigate the effect of 23.4% hypertonic saline(HTS)on intracranial pressure(ICP), cerebral peffusion pressure(CPP), cerebral blood flow(CBF)in poor-grade patients with subarachnoid hemorrhage(SAH).Methods Sixteen patients(Glasgow coma score ≤ 8)with poor-grade SAH received 23.4% hypertonic saline intravenously for elevated ICP.ICP, mean arterial pressure(MAP), CPP and the middle cerebral artery flow velocity(FV)were observed and recorded before and at 30, 60, 90,120, 150, 180 min after the injection respectively.Results Thirty minutes postinfusion, a significant increase in MAP, CPP, FV was seen together with a decrease in ICP(P<0.05).ICP remained reduced for 180 minutes, CPP and FV remained elevated for 90 minutes(P < 0.05).Conclusions HTS can significantly decrease ICP and improve CBF in patients with poor-grade subarachnoid hemorrhage and may be used for reversal of pathophysiologic changes caused by cerebral ischemia.

Objective To examine the practicability and security of the LigaSureTM vessel-sealing system in radical gastrcctomy.Methods Seventy patients of stage Ⅰ～Ⅲ gastric cancer undergone radical gastrectomy were analyzed retrospectively.Thirty-five radical gastrectomy were performed with LigaSureTM vessel-sealing system,the other 35 eases were performed without LigaSureTM.The operative duration,volume of intraoperative hemorrhage,and postoperative complications were analyzed.Results There were significant difference in both operative duration[(159.9±24.7)min vs(172.6±23.7)min,P＜0.05]and volume of intraoperative hemorrhage[(335.7±40.3)ml vs(371.7±43.2)ml,P＜0.01].There was no significant difference in the postoperative complications between LigaSureTM group and conventional method group.All patients recovered without severe postoperative complications.Conclusion Radical resection of gastric cancer using LigaSureTM instead of conventional hand tie method appears to he shorten operative duration,decreased volume of intraoperative hemorrhage.And the technique is convenient and safe.

Objective To investigate changes in the intraocular pressure(IOP) and anterior chamber angle in patients with chronic renal failure before and after hemodialysis. Methods Fifty?eight patients(116 eyes) with chronic renal failure were measured with Goldmann applanation tonometer and anterior segment optical coherence tomograph. The patients were divided into three groups based on gonioscopy results:the narrow angle group(22 eyes),the Iris neovascular group(3 eyes)and the open angle group(91 eyes). IOP was measured by Goldmann applanation tonometer in patients in the three groups before and after hemodialysis. Anterior chamber angle opening distance (AOD) was detected by anterior segment optical coherence tomograph before and after hemodialysis. The blood urea nitrogen,creatinine,albumin were also determined before and after hemodialysis. All changes in the parameters were analyzed with a paired t test. Results The IOP in narrow angle eyes and in neovascular eyes increased significantly after hemodialysis ,while the IOP in open angle eyes showed no significant changes. The AOD decreased significantly after hemodialysis. The blood urea nitrogen and creatinine decreased significantly in 58 patients,while albumin increased after hemodialysis. Conclusion The IOP in narrow angle eyes and in neovascular eyes increased after hemodialysis ,correlating with the resistance increase of aqueous outflow pathway and the change of plasma osmotic pressure. As a result ,it is recommended that the condition of eye of patients with chronic renal failure should be checked ,and patients should receive appropriate controlling measure or treatment before hemodialysis.
