Objective To report a retroperitoneal laparoscopic surgery for ureteropelvic junction obstruction (UPJO) by double renal veins.Methods A 28-year-old male patient with left low back pain for 6 months was diagnosed as left hydronephrosis and UPJO.A ureteral stent had been placed 3 months before and failed to improve hydronephrosis,so the ureteral stent was pulled out.CT scan showed that left UPJ went through the two renal veins,suggesting UPJO.Nephrogram showed that left GFR and right GFR were 35 ml/min and 34 ml/min,respectively.These results indicated mechanical obstruction of left upper urinary tract.The patient underwent retroperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty.Results The surgical procedure was successful.Two left renal veins were found,and the ventral one was in front of ureter,compressing the ureter.An aberrant renal artery went into left kidney with the ureter.0.5 cm stenosis of ureteropelvic junction was excised,and pyeloplasty was performed.A ureteral stent was placed into the ureter,then the pelvis and the ureter were sew up in front of the ventral renal vein.The surgical time was 240 min,and blood loss was 50 ml.Postoperative hospital stay time was 4 d.During 4 months' follow up,hydronephrosis was attenuated significantly.Conclusion Retroperitoneal laparoscopic surgery for UPJO with aberrant two renal vein might be a minimally-invasive and effective procedure.

ObjectiveTo observe the effects of XinShu parenteral solution (XSPS) on the activation of platelet, the activity of fibrinolysis system after intima denudation of rabbits.Methods20 male Japanese white rabbits (2.5±0.5)kg were randomly divided into the control group and XSPS group .The celiac arterial endothelium of all rabbits were denuded with balloon. Before the operation and 3d, 7d, after balloon denudation, vein blood samples were obtained from each group rabbits for measurement of α granule membrane protein of platelets(GMP-140), tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor-type Ⅰ(PAI-1).ResultsPlasma GMP-140 and PAI-1 activity obviously elevated after balloon injury, and there was a little elevation in plasma t-PA activity in control group. Activity of plasma GMP-140 in XSPS group remained bottom level after balloon injury, and there was a significant increase in plasma t-PA activity and a marked reduce in PAI-1 activity in XSPS group. There was a notable difference between group B and group C (P<0.05). ConclusionXSPS obviously inhibits platelet activation, and improves fibrinolysis activity after balloon injury.

OBJECTIVETo observe the effect of transcutaneous acupoint electrical stimulation (TAES) combined dexmedetomidine on hemodynamic of intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention, and their protection for brain Injury.

METHODSTotally 108 intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention were randomly assigned to the electroacupuncture (EA) group and the control group according to random digit table, 54 in each group. All patients were anesthetized with dexmedetomidine. Patients in the EA group were needled at bilateral Neiguan (PC6), Lieque (LU7), and Yunmen (LU2). Parameter setting was as follows: The dilatational wave at 1. 5 Hz, strength 2 - 4 mA, 30 min. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were compared between the two groups immediately after entry into the room (T0), after administration (T1), intubating (T2), resuscitation (T3), extubation (T4), and leaving the operating room (T5). Levels of S100β protein (S100β) and neuron specific enolase (NSE) were compared between the two groups at T0, immediately after surgery (T6), 6 h after operation (T7), 12 h after operation (T8), and 24 h after operation (T9).

RESULTSCompared with the same group at T0, SBP, DBP, MAP, and HR were significantly reduced in the two groups at T1-T5(P <0. 05), serum levels of S100β and NSE in the two groups were significantly increased at T6-T9 (P<0. 05). Compared with the control group at T1 - T5, SBP, DBP, MAP, and HR decreased in the EA group (P <0. 05). Compared with the control group at T6-T9, serum levels of S100β and NSE decreased in the EA group (P <0. 05).

CONCLUSIONTAES combined dexmedetomidine could effectively maintain stable hemodynamics of intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention, and regulate their serum levels of S100β and NSE.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.

METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.

RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).

CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

OBJECTIVETo investigate the applications of percutaneous screw fixation for the treatment of pelvic fractures and its related surgical considerations.

METHODSFrom June 2010 to June 2012,19 patients with pelvic fractures were treated with percutaneous hollow screws. There were 13 males and 6 females, with an average age of 41 years (ranged from 22 to 58 years). Fractures were caused by traffic accidents in 11 cases, by falling down from high place in 8 cases. Based on the Tile classification, there were 15 cases of Tile C type and 4 case of Tile B type. The indexes such as screw inserting time, intraoperative blood loss, complications, functional recovery and reduction conditions were observed. Fixation methods included sacroiliac screws, cannulated screw fixation of the pubic ramus and cannulated screw fixation of the pubic symphysis separation.

RESULTSAnatomical reduction achieved in 7 cases, satisfactory reduction 11 cases, and unsatisfactory reduction 1 case. Union time of fracture union ranged from 8 to 12 weeks (mean 10 weeks). Wound infection,ununion of fracture and nerve injuries were not found. According to the Majeed standards, 12 patients obtained an excellent results, 6 good and 1 fair.

CONCLUSIONPercutaneous screw fixation for the treatment of pelvic fractures under fluoroscopy has several advantages such as less trauma, less blood loss, fewer rates of complications, reliable fixation and no blood transfusion, which can reconstruct the stability of the pelvic ring, but it needs adequate preoperative preparation and high requirements for the surgeon.

Objective To investigate the therapeutic effect and the detailed mechanisms of intraarterially delivery of bone marrow mesenchymal stem cells ( BMSCs) for treatment of middle cerebral artery occlusion (MCAO) in rats.Methods BMSCs were isolated,purified and amplified with the adherence culture method.BMSCs were labeled with 5-bromo-2-deoxyuridine ( BrdU ) (10 μmol/L) for 48 h before transplation.Surface antigens of CD90,CD29,CD106,CD34,CD45,CD11b were identified by flow cytometry.The MCAO model was established with suture emboli method.In this study,3×106 BMSCs were injected into rats with MCAO through intraarterial route at day 7 after stroke.The effects on functional and physical recovery were assessed with the behavioral tests (mNSS test and adhesive test) and body weight.Bielshowsky-Luxol Fast Blue double staining was used to demonstrate the reconstruction of axon and myelin.The Brdu-labeled BMSCs in vitro and in vivo were detected with direct immunofluorescent staining.The expression of neuron specific enolase ( NSE),neurite outgrowth inhibitor-A ( Nogo-A),synaptophysin (SYN),ki-67 nuclear antigen (Ki-67),glial fibrillary acid protein( GFAP),vascular endothelial growth factor ( VEGF) in brain were analyzed with immunohistochemical staining.Results Flow cytometry indicated that the positive rates of high expression of CD90,CD29,CD106 in BMSCs were respectively 91.70%,88.40% and 52.20%.Meanwhile,the positive rates of low expression of CD34,CD45,CD11b in BMSCs were 2.70%,5.65% and 7.82%,respectively.There was a significant difference in behavioral tests ( mNSS test and adhesive test) between BMSCs group and PBS group at day 21,28,35 after MCAO (mNSS:4.89 ±1.36,7.00 ±1.67,3.78 ±1.30 and 6.33 ±1.21,2.44 ±1.13,5.67 ± 1.51;t =2.69,3.83,4.75;adhesive test:54.00 ± 10.48,68.17 ± 11.09,36.89 ±9.80 and 59.33 ± 12.40,23.44 ± 9.04,46.50 ±9.38;t =2.51,3.92,4.77;P ＜0.05).Meanwhile,a significant difference in body weight was discovered between them at day 28,35 after MCAO.In BMSCs group,the area of corpus callosum in the ipsilateral hemisphere was significantly enlarged,the positive number of Brdu,SYN,Ki-67,GFAP,VEGF in brain was significantly increased,the expression of Nogo-A in brain was significantly decreased,nevertheless,the number of NSE-positive cells in brain and the infarct volume were not significant different from PBS group at day 35 after MCAO.Conclusions These results suggest that intra-arterial transplantation of BMSCs is an efficient treatment protocol for stroke.Treatment with BMSCs increases endogenous cells proliferation,angiogenesis,synaptogenesis,enhances axonal regeneration and the protective function of astrocytes,all of which may contribute to neurological functional recovery.

Objective To review the clinical characteristics of paraganglioma of the urinary bladder with 5 cases reprt.Methods The clinical data of 5 patients (2 males and 3 females,age 23-68 years)with paraganglioma of the urinary bladder were reported.Two cases were diagnosed by ultrasonography during health examination,1 case was found by hematuria,1 had difficulty of voiding,and 1 presented with palpitation,chest discomfort while urination.Two cases were clinical diagnosed as bladder paraganglioma,1case urachal carcinoma,and 2 cases bladder tumor.Cystoscopy showed a protruding tumor within the bladder or bladder had compressed changes.One case of tumor located in the triangle,1 in the posterior wall,1in the top,2 in the anterior wall.Three cases of biopsy were negative.Three cases of preoperative endocrine examinations showed norepinephrine significantly higher.Results Laparoscopic partial cystectomy was performed in 3 cases,open partial cystectomy in 1 case,and transurethral resection of bladder tumor (TURBT) in 1 case.One case had the complication of stress cardiomyopathy during TURBT,3 cases found intraoperative hypertensive crisis.The bleeding volume was 20-800 ml (average 126 ml),and I case received blood transfusion.During the follow-up period for 3-48 months,the blood pressure was normal,and no recurrence was found.Conclusions Bladder paraganglioma is uncommon and easily misdiagnosed.For the patients with bladder tumor,accompanied by changes in blood pressure,palpitations during urination should be highly suspicious of bladder paraganglioma.Partial cystectomy is the main treatment method.

Objective To investigate the effect of extracellular histones (EH) on intestinal mucosal barrier function in mice and the correlation of EH with the pathogenesis of sepsis.Methods Twenty male C57BL/6 mice were assigned into experiment group (n =10) and control group (n =10) according to the random number table.Same dose (50 mg/kg) of EH and saline were administered through the caudal vein of mice in experiment and control groups respectively.Blood and intestinal samples in each group were collected 3 h after the administration.Morphology of intestinal mucosal tissue was detected by light scope and transmission electron microscope.Expressions of tight junction related proteins (ZO-1,Occludin and Claudin-1) were detected by western blot.Plasma levels of diamine oxidase (DAO) and intestinal fatty acid binding protein (I-FABP) were determined by ELISA method.Plasma level of endotoxin (ET) was determined by limulus test.Results Under transmission electron microscope,experiment group showed disorganized microvilli of intestinal epithelial cells with partially twisted,broken and lost,unclear tight junctions,and widened cellular space.Under light scope,experiment group showed substantial inflammatory cell infiltration in the intestinal wall,disorganized intestinal villi,edema and hemorrhage of mucosa and submucosa,and edematous goblet cells.Experimental versus control group showed significant reduction in levels of Claudin-1 (0.587 7 ±0.060 6 vs.0.677 2 ±0.038 3),Occludin (0.1277±0.0857vs.0.4306±0.0869) and ZO-1 (0.393 3±0.080 8 vs.0.812 8± 0.096 3) (P ＜ 0.05).Experimental versus control group showed significantly up-regulated plasma levels of DAO [(1.61 ±0.20) U/ml vs.(0.69 ± 0.15) U/ml],I-FABP [(548.5 ± 36.8) EU/ml vs.(178.8±26.9) EU/ml] andET [(0.182±0.076) EU/mlvs.(0.091 ±0.029) EU/ml](P＜0.05).Conclusion EH can obviously impair the integrity of intestinal mucosal barrier in mice and hence induce endotoxin translocation.

Objective To explore the change of plasma orexin A concentration and the correlation between plasma orexin A concentration and energy intake in obese children.Methods Fasting plasma orexin A concentrations,boaly mass index(BMI) and energy intake were measured in 48 obese children(obese group) and 48 healthy children(healthy control group),and these indexes were compared,the correlation between plasma orexin A concentration and BMI,energy intake were analyzed.Results 1.The plasma orexin A concentration in obese group was significantly lower than that in healthy control group(F=5.632 P=0.008).2.In obsess group,there were negative correlation between plasma orexin A concentration and BMI(r=-0.478 P=0.012),positive correlation between plasma orexin A concentration and total energy intake(r=0.503 P=0.007),fat intake(r=0.659 P=0.006) and protein intake(r=0.381 P=0.026),and there was negative correlation between plasma orexin A concentration and carbohydrate(r=-0.316 P=0.022).3.In healthy control group,there were negative correlation between plasma orexin A concentration and BMI(r=-0.491 P=0.018),positive correlation between plasma orexin A concentration and total energy intake(r=0.512 P=0.009),fat intake(r=0.406 P=0.005),protein intake(r=0.313 P=0.020),and carbohydrate(r=0.432 P=0.025).Conclusions Orexin A may be involved in regulation of energy metabolism in obese children,and the interaction between plasma orexin A and energy intake might be different in different nutritional status in children.
