A cutaneous branch of the suprascapular nerve was observed in 9 from 180 Chinese adult arms (5.0?1.62%), it has been found bilaterally in 3, and unilaterally in other 3 male cadavers.The cutaneous branch arose from the stem of an essentially normal suprascapular nerve under the superior transverse scapular ligament. After passing between the coraco-clavicular and coraco-acromial ligaments the cutaneous branch pierced obliquely the deltoid muscle and supplied the proximal third of the antero-lateral aspect of the arm. The distribution territory of the cutaneous branch coincided with the anterior half of the deltoid muscle.

Objective To investigate the effect of isoflurane pretreatment on hypoxia/reoxygenation (H/R)-induced syndecan-1 shedding from human umbilical vein endothelial cells (HUVECs) . Methods HUVECs were cultured in EMB-2 medium and randomly divided into 3 groups ( n = 32 each) : control group (group C), H/R group and isoflurane pretreatment group (group I). H/R was produced by 4 h exposure of HUVECs to hypoxia followed by 2 h reoxygenation in H/R and I groups. HUVECs were exposed to the mixture of 5% CO2 and 95% O2 for 30 min and then cultured in normal culture atmosphere (21% O2) in group C. In group I, HUVECs were expased to 1.73% isoflurane and incubated for 30 min before H/R. The syndecan-1 expression, concentrations of shed syndecan-1 in the medium, and cell permeability and viability were measured at the end of reoxygenation. Results Compared with group C, the shed syndecan-1 concentration in the medium and cell permeability were significantly increased, while the syndecan-1 expression and cell viability decreased in H/R and Ⅰ groups ( P ＜ 0.01) . Compared with group H/R, the shed syndecan-1 concentration in the medium and cell permeability were significantly decreased, while the syndecan-1 expression and cell viability increased in group Ⅰ (P ＜ 0.01) . Conclusion Isoflurane pretreatment can protect HUVECs against H/R injury through inhibiting the syndecan-1 shedding.

AIM: To investigate the dynamic changes of ATPases and NOS activities and NO production at different anesthesia phases using thiopental and propofol andifferent anesthetic phases (induction, anesthesia, restoration, and awake), the activities of NOS and ATPase and NO production in cortex and brain stem were meagroup. RESULTS: Ca2+ -ATPase and Na+ ,K+ -ATPase activities in the cortex and brain stem were significantly decreased after administration ofthiopental and propofol,especially at induction, anesthesia, or even restoration phase of thiopental group (P＜0.05, P＜0.01) and at anesthesia phase of propofol group (P＜0.05). NOS activities and NO production decreased from induction to restoration phase with thiopental and propofol anesthesia (P＜0.01). The parameters were returned near to the normal at awaken phase. CONCLUSION: Activities of ATPases and NOS and the production of NO may mediate the anesthesia effects of thiopental and propofol in the rat cortex and brain stem.

Objective To assess the regional left ventricular (LV) rotation motion in the patients with rheumatic mitral stenosis (MS) with velocity vector imaging (VVI).Methods This study included 38 patients with isolated MS (mild,moderate and severe) and 55 healthy control subjects.Short-axis parasternal views at the basal and apical level of LV were taken.Peak value of rotation angle and rotation velocity,as well as time to peak value were measured by VVI workplace offline respectively.Results ①In the healthy control subjects LV rotates clockwisely at the base and counterclockwisely at the apex,the same as the patients with MS.② In th patients with MS,rotaion angle and rotation velocity were significantly reduced at the apical level(P ＜0.001),rotation velocity were significantly reduced at some segments of basal level (anterior,lateral,septal) (P ＜ 0.05).③Compared with the healthy control,the difference of time to peak roation angle between base and apex was significantly longer in patients with MS (P ＜0.05).④ There were no significant differences among mild,moderate and severe MS (P ＞0.05).Conclusions The patients with MS may suffer from systolic dysfunctin even in the early stage identified by the alteration of LV rotation motion,which is independent of the hemodynamic severity of MS.

Objective To investigate the effects of sulforaphane (SFN) on the proliferation of prostate cancer DU145 cells and hypoxia-inducible factor-1α(HIF-lα) expression,and to explore the possibility of SFN in the prevention of prostate cancers.Methods The DU145 cells were treated with different doses and different time of SFN.The cell proliferation viability were measured by 3-(4,5)-dimethylthiahiazo (-zy1)-3,3,5-di-phenytetrazo`liumromide (MTT) proliferation and cytotoxicity assay kit.The hypoxia tumor microenvironment was stimulated by pretreating cells with 1％ O2,HIF-lα expression and vascular endothelial growth factor (VEGF) activitity were detected by Western-blot and ELISA,respectively.Results SFN had an inhibitory effect on the proliferation of human prostate cancer DU145 cells in a dose-and time-dependent manner.The cell proliferation inhibition rate exceeded 50％ in more than 20 μ mol/L SFN-treated groups after 48 hours.SFN could inhibit the expression of HIF-1α induced by 1％ O2 and VEGF activity.10 μmol/L SFN showed inhibitory effect on the expression of HIF-1α after 24 hours.20 μ mol/L SFN showed a significant inhibitory effect on the expression of HIF-1α after 12 hours.And peroxidase had synergistic inhibition on HIF-1α.Conclusions SFN can inhibit the proliferation of DU145 prostate cancer cells and HIF-lα expression.SFN can be used as a potential chemotherapeutic agent against human prostate cancer.

BACKGROUND:Precision attachment has been widely used in complete denture because of its strong retention, good appearance, comfort and durability. Among them, magnetic attachment and bal-cap attachment are commonly applied for mandibular complete denture.
OBJECTIVE:To compare the clinical effects of magnetic attachment, bal-cap attachment and traditional clasp retainer used in the mandibular removable partial denture.
METHODS:A total of 45 patients with dentition defects were included in this study, they were treated with magnetic attachment, bal-cap attachment and traditional clasp retention of mandibular removable partial denture. Fifteen patients received one means. The satisfaction of patients and the periodontal health of abutments were observed after 3 years.
RESULTS AND CONCLUSION:Comparison of the patient satisfaction showed that, the aesthetics, retention conditions, masticatory function and comfort in magnetic attachment group were significantly better than traditional clasp retention group (P<0.05). The aesthetics and comfort in bal-cap attachment group were also better than traditional clasp retention group (P<0.05). There were significant differences on the retention conditions and comfort between magnetic attachment group and bal-cap attachment group (P<0.05). Gingival index was the highest in magnetic attachment group, then in bal-cap attachment group, and the lowest in traditional clasp retention group (P<0.05). The abutment tooth mobility degree was the lowest in magnetic attachment group, then in bal-cap attachment group, and the highest in traditional clasp retention group (P<0.05). The periodontal pocket depth in magnetic attachment group and bal-cap attachment group was lower than that in traditional clasp retention group (P<0.05). The alveolar bone height was the highest in magnetic attachment group, then in bal-cap attachment group, and the lowest in traditional clasp retention group (P<0.05). Experimental findings indicate that, precision attachment over-denture retention superior to traditional clasp removable partial denture in mandibular denture repairing. Magnetic attachment can provide better retention power and better protect the health of periodontal tissue compared with bal-cap attachment.

Aim To investigate the effect of thiopental sodium on the release of glutamate and GABA from synaptosomes of rats prefrontal cortex. Methods Synaptosomes were made from rats prefrontal cortex and incubated with artificial cerebral and spinal fluid (aCSF), then divided into five groups: group base release (Base), group thiopental sodium 10 ?mol?L -1 (THS 10), group thiopental sodium 30 ?mol?L -1 (THS 30), group thiopen tal sodium 100 ?mol?L -1 (THS 100) and group thiopental sodium 300 ?mol? L -1 (THS 300). Various concentrations of thiopental sodium were added to aC SF, the release of glutamate and GABA were performed under 37℃ and measured using reversed-phase high-performance liquid chromatography (RP-HPLC). When Ca 2+-independent release of glutamate and GABA were studied, Ca 2+ was omitted from aCSF.Results Compared with Base, thiopental sodium 30 , 100 and 300 ?mol?L -1 inhibited Ca 2+-dependent release of gluta mate evoked by KCl or veratridine significantly (P
