Objective To investigate the effect of different modes of one-lung ventilation ( OLV) on respiratory mechanics, hemodynamics and arterial oxygen tension ( PaO2) in pediatric patients. Methods Thirty-four ASA Ⅰ - Ⅱ patients (14 male, 20 female) aged 2-10 yr, weighing 8-26 kg undergoing abdominal surgery or operations on extremities were enrolled in this study. The patients were premedicated with intramuscular phenobarbital 2-3 mg ? kg-1 and atropine 0.015 mg ? kg-1 . In the operating room the patients were given intramuscular midazolam 0.25 mg? kg-1 and ketamine 2.5 mg ? kg-1 before intravenous line and EGG, NIBP and SpO2 monitoring were established. Anesthesia was induced with intravenous fentanyl 3-5 ?g kg-1 and vecuronium 0.1 mg? kg-1 and maintained with isoflurane inhalation supplemented with intermittent iv boluses of fentanyl and vecuronium. In patients aged over 5 yr Univent (Fuji Corpi) was inserted and left main bronchus was blocked during OLV. In patients less than 5 yr ordinary tracheal tube was inserted and was advanced into right main bronchus during OLV. Correct positioning of the tube was checked by fiberoptic bronchoscopy or auscultation. The test consisted of three steps : firstly two-lung ventilation (TLV) with volume-control mode; secondly OLV with volume-control mode;lastly OLV with pressure-control mode. During first and second step VT was set at 8-10 ml kg-1 and respiratory rate was adjusted to maintain PETCO2 between 4.5-6.0 kPa. During the third step (OLV with pressure-control mode) the inspiratory pressure was set according to the plateau pressure during step 1 and 2 (volume-control mode). Each step was maintained for 25 min before respiratory mechanics , hemodynamics and PaO2 were measured and recorded.Results During OLV with volume-control mode (second step) , peak pressure (Ppeak), plateau pressure (Pplat) and airway resistance (Raw) were significantly higher but dynamic compliance was significantly lower, cardiac output (CO) and stroke volume (SV) were significant lower but systemic vascular resistance (SVR) was significantly higher and PaO2 was significantly lower than those during first step (two lung ventilation with volume-control mode) (P

Objective To study the effects of proprioception training on the motor function and ability in the activities of daily living (ADL) of hemiplegic stroke patients. Methods Forty hemiplegic stroke patients were divided into study group and a control group ( n =20 in each).The two groups received conventional rehabilitation treatment and pharmacotherapy,but the study group received additional proprioception training.The Technobody proprioceptive system assessment,the Fugl-Meyer lower limb assessment (FMA),the Berg balance scale (BBS) and the modified Barthel index (MBI) were used to evaluate their proprioceptive ability,lower limb motor function,balance and ADL ability,before and after 4 weeks of treatment. Results After 4 weeks,proprioception,lower limb motor function,balance and ADL ability had all improved significantly in the experimental group.Lower limb motor function,balance and ADL ability had also improved significantly in the control group,but they showed no significant change in their average proprioceptive ability.The improvement in the experimental group was superior to that of the control group in terms of proprioceptive ability,balance and ADL ability. Conclusions Proprioception training can improve the motor function (including the proprioception and balance) and ADL ability of hemiplegic stroke patients.

Based on the results of the morphologic studies on genus Dioscorea, the paper summarized the entire chemical constituent that isolated from this genus and analyzed it with the methods of chemotaxonomy. The rules of the chemical constituent and pharmacodynamic effects were analyzed. Seventeen species which belong to Sect. Stenophora Uline of Dioscorea contain steroidal sapogenin. Other species with different main components such as polysaccharide and tannin have have different effects. This chemotaxonomic view point will conduce to establish a phylogeny of the genus Dioscorea.

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.
