Objective To investigate the efficacy of laparoscopic transcystic duct exploration for cholecystolithiasis complicated with stones in the non-dilated common bile duct.Methods Before the resection of the cyst,the cystic duct was cut under a laparoscope,and then a C tube was inserted for cholangiography.Stones in the common bile duct were removed under the guidance of C-arm X-ray.Then,C-tube drainage was carried out after removal of the calculi.Results The stones were completely removed in all of the 36 cases with a mean operation time of 125.4 minutes(90-150 minutes).The C-tube was withdrawn in 3 or 4 days after the operation.The mean postoperative time of this series was 4 to 7 days.The patients were followed up for 3 months,during which no patients had biliary leakage,residual stones,or stenosis or dilation of the common bile duct.Conclusions Laparoscopic transcystic duct exploration is minimally invasive,safe,and effective for cholecystolithiasis complicated with stones in the non-dilated common bile duct.

Aim: To develop and compare the ultra-performance liquid chromatography( UPLC) and HPLC methods for the determination of dihydroflavonoids in Smilacis glabrae Rhizoma, and establish the quality evaluation system of the above-mentioned crude drug. Methods: Four dihydroflavonoids in the crude drugs collected from 15 localities were determined using the UPLC and HPLC methods, respectively. The resolution, sensitivity, precision, accuracy and the content determination results of the four compounds were compared between the two methods. Results: The UPLC method was more fast and sensitive than the HPLC method with no significant differences among the linearity range, precision, accuracy and the content determination results between the two methods. Conclusion: The developed HPLC method was proved practicable and reliable for the quality control of Smilacis glabrae Rhizoma. The UPLC method was provided to be a more sensitive, fast and solvent-saving method compared to HPLC and can be applied in the quality evaluation of Chinese medicines.

12.Meanwhile 10 healthy elderly subjects of similar age and gender ratio were matched as controls.There was no significant difference of age,gender,education,onset duration and MMSE.Attention task was carded out with silent color-word task:all participants pressed the left or right button to select the answer of congruence or incongruence when color nouns in red,green,blue or yellow ink appearing on the left part of screen and a target color appearing on the right part of the screen by.During the tasks,reaction time,false ratio,missing ratio and fMRI image acquisition was respectively recorded,which were later analyzed on SPSS 11.0 statistical parametric mapping software 2 (SPM2) respectively.Results The reaction time in dAD,AD and control group were (2214.4?1071),(2020.6?558.3) and (840.0?254.5) ms respectively.The false ratio were 8.3%,6.9% and 0.7% respectively,and the omit ratio were 3.6%, 2.9% and 0 respectively.Either AD with or without depression was slower than the controls in reaction time (P

Objective: To investigate the protective effect of dimethylsulfoxide (DMSO) on axon degeneration. Methods: Cultured rat superior cervical ganglia were treated with DMSO (100%, 10 μl) per well to disconnect axons from the cell bodies. SCGs in DMSO control group were treated with a mixture of DMSO (10 μl) and medium (2 ml) per well; in positive control group were transfected with herpes simplex virus over-expressing Wlds protein and the cell body was eliminated; and in blank control group were treated with 10 μl PBS. The separated axons were fixed with 4% poly formaldehyde at 0, 4, 8, 12 and 24 h after treatment with DMSO for immunostaining with specific antibody to microtubulin. Thus, the changes of axonal structure were investigated. The axonal protein was collected and the degeneration of neurofilament was detected by Western Blotting. Results: In DMSO disconnected group, the axonal morphology and structure showed no obvious change at 12 h post disconnection, but slight degeneration was observed at 24 h post disconnection. The degradation of microtubulin was obviously slowed down and their axonal structures maintained intact 12 h later. The neurofilament could be detected 12 h after disconnection. The above changes in disconnected group were similar to those in positive control group. No obvious protective effects on axonal degeneration were observed in blank and DMSO control groups. Conclusion: Local high concentration of DMSO can delay axonal degeneration, which indicates that DMSO can be used for adjuvant treatment of neurodegenerative diseases.

Objective To observe the pharmacological characteristics of a novel antihypertensive drug iptakalim hydrochloride (Ipt) by dilating large and small arteries. Methods The vasodilating action of Ipt was studied using isolated rat tail artery helical strips and aortic rings. Results The vasodilating action of Ipt at 10 7-10 3mol/L was observed in rat tail artery strips precontracted with potassium chloride (KCl) in a concentration and endothelium dependent manner, but no significant vasodilating effect was seen on rat aortic rings. Ipt-induced relaxation in tail artery was significantly greater in spontaneous hypertensive rats than that in normotensive rats. The vasodilating actions of Ipt in small arteries could be markedly antagonized by glibenclamide, an inhibitor of ATP-sensitive potassium channels. Conclusion The results suggest that iptakalim hydrochloride has a selective vasodilating action in small arteries, and the action is related to activation of ATP-sensitive potassium channels.
