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 diagnostic value of tumor marker measurement in biliary juice obtained during endoscopic retrograde cholangiopancreatography (ERCP) in differential diagnosis of suspected biliary-pancrentic diseases.Methods ERCP was performed in patients with suspected biliarypancreatic lesions that could not be diagnosed by routine methods including ultrasonography,MRCP,blood biochemistry and serum tumor marker test,and biliary juice was obtained to measure tumor markers including CEA and CA199.A total of 29 patients with definitive diagnosis were recruited and divided into benign and malignant groups.Serum biochemical findings and tumor markers were compared between 2 groups.The diagnostic value of uhrasonography,EUS,MRCP,ERCP and ERCP combined with biliary tumor markers were also compared.Results There was no significant difference in serum biochemical findings,serum CEA,serum CA19-9 or biliary CA19-9 between 2 groups,while the average biliary CEA in malignant group was significandy higher than that in benign group (P＜0.001).The accuracy of ERCP combined with biliary tumor markers in diagnosing suspected biliary-pancreatic diseases was 69.0%,which was higher than that of ultrasonography (6.9%),MRCP (37.9%) and ERCP (41.4%),respectively.Conclusion The diagnostic accuracy of suspected biliary-pancreatic diseases can be improved through ERCP combined with biliary CEA test,which is helpful in differential diagnosis between benign and malignant lesions.

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.

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 investigate the effect of Xuebijing injectiong on lipopolysaccharide(LPS)-induced apoptosis of CD4+CD25+regulatory T cells(Tregs)and immune function of effector T cells(Teff)in vitro.Method CD4+CD25+Tregs isolated from rat spleens were divided into the control group,anti-CD3/CD28 group,anti-CD3/CD28+LPS group,anti-CD3/CD28+Xuebijing injection group,and anti-CD3/CD28+LPS+Xuebijing injection group.The apoptosis rate and expression of forkhead/winged helix transcription factor p3 (Foxp3)and cytotoxic T-lymphocyte-associated antigen 4(CTLA-4)of CD4+CD25+Tregs were detected by flow cytometry(FCM),and the secretion of IL-10 of Tregs was measured by ELBA on day 3.CD4+CD25-T cells were co-cultured with CD4+CD25+Tregs(1:1)for 68 hours,proliferative activity of Teff was determined by MTT,and interleukin(IL)-2/sIL-2Rα levels were measured by ELISA.Results The apoptosis rate of CD4+CD25+Tregs in anti-CD3/CD28 group was 33.70± 3.06%,which was significantly higher than that in control group(12.84±0.84%).Also,apoptosis rate of CD4 CD25+Tregs in anti-CD3/CD28+LPS+Xuebijing injection group(45.13±2.70%)was much higher than that in anti-CD3/CD28+IPS group(29.41 ± 1.63%,P＜0.01).The expression of Foxp3 as well as CTLA-4,and the secretion of IL-10 were markedly decreased along with increases in the apoptosis rates.Compared with control group(54.48%),the mean inhibitory rate of Teff proliferative activity in response to Con A was significantly decreased in anti-CD3/CD28+Xuebijing injection group(31.26%,P＜0.05),and it was markedly decreased in anti-CD3/CD28+LPS+Xuebijing injection group comaped to anti-CD3/CD28+LPS group(P＜0.01).In addition,IL-2 levels in the supernatant of anti-CD3/CD28+Xuebijing injection group and anti-CD3/CD28+LPS+Xuebijing injection group were significantly higher than those of anti-CD3/CD28+IPS group(P＜0.01).Conclusions The inhibitory activity of CD4+CD25+Tregs on Teff appears to be upregulated by IPS stimulation in vitro,and Xuebijing injection could markedly enhance apoptosis of CD4+CD25+Tregs,thereby improving suppressive immune function of Teff.
