Objective To study the sources and the relationship between the management and the outcome of hemorrhage after cephalic pancreatoduodenectomy.Methods The clinical data of 370 patients who underwent pancreatic resection at the Lihuili Hospital and the Second Affiliated Hospital of Zhejiang University were retrospectively analyzed.Results Postoperative bleeding occurred in 35 patients with 11 deaths.Among those intraabominal bleeding occurred in 14 cases and gastrointestinal hemorrhage occurred in 22,with one case suffering from both.Bleediug developing within 72 hours after operation in 12 cases (early-stage group),which was caused by improper intraoperative homeostasis.In other 23 cases,bleeding 72 hours after operation(later stage group)was caused by the erosion following pancreatic and/or bile leakage.Relaparotomy was performed in 13 cases and endoscopic homeostasis was performed in 3. Relaparotomy or endoscopic homeostasis was superior to that of conservative therapy in the early-stage group (P0.05).Pancreatic or bile leakage was identified as the significant risk factors for the postoperative bleeding.Conclusions In order to prevent the postoperative hemorrhage and to reduce the mortality of pancreatic resection,skillful techniques,expeditious homeostasis,proper management of stump pancreas and the prevention of pancreatic and bile leakage are essential.

Objective To observe the results and reality of transurethral resection of bladder tumor(TUR-Bt) with upside down loop and plsamakinetic in the prevention of obturator nerve reflex.Methods A total of 211 patients with lumbar anesthesia received TUR-Bt.Firstly,the tumor tower above bladder wall was cut with the traditional way.When intraoperative findings were obturator nerve reflex,or to the obturator nerve mapping area,operation should be changed to superimpulse plasma column electrode vaporization to cut off residual tumor tissue,then after flipping the loop,the residual tumour was resected with upside-down loop from the tumour side wall.Results In 211 cases,192 cases had a little obturator nerve reflex,but the movement of body was not obvious,which did not influence the operation.The serious complication,such as perforation of bladder and injury of nerve and vessel,did not occur.Conclusions The lateral resection of bladder side wall tumour with upside-down loop can effectively avoid strong obturator nerve reflex,which is safe,uncomplicated,and efficacious and it does not increase the additional outlay and hurt.

Objective To investigate the prognosis of children with acute kidney injury(AKI)treated with peritoneal dialysis(PD)following cardiopulmonary bypass.Methods A retrospective study of 46 children aged under 14 years old with AKI treated by using PD following cardiopulmonary bypass from Jan.2006 through Dec.2010.All of them were divided into three groups,namely group A(AKI Ⅰ),group B(AKI Ⅱ)and group C(AKI Ⅲ)according to the stratification of RIFLE criteria.The timing of PD was depended on the phase of AKI.The ICU length of stay,total duration of mechanical ventilation,total amount of peritoneal dialysate and the length of PD were compared among three groups.Their APACHE Ⅱ score,sequential organ failure assessment(SOFA)score,serum interleukin-6(IL-6),oxygenate index,serum creatinine,and mean arterial pressure were also compared between before PD and after PD for 48 hours.One-way ANOVA was used for statistical analysis between different phases of AKI.Data got before PD and after PD for 48 hours were analyzed with paired Student' s t-test.Results The APACHE Ⅱ score,SOFA score and serum IL-6 before PD were higher in patients with phase Ⅲ of AKI than those in patients with phases Ⅰ and Ⅱ of AKI(P ＜ 0.01).There were no significant differences in APACHE Ⅱ score and SOFA score between patients with phases Ⅰ of AKI and patients with phase Ⅱ of AKI before PD(P ＞0.05),but serum IL-6 before PD,ICU length of stay,total duration of mechanical ventilation,total amount of peritoneal dialysate and the length of PD in patients with phase Ⅱ of AKI were higher or longer than those in patients with phase Ⅰ of AKI(P ＜ 0.01).After PD for 48 hours,APACHE Ⅱ score,SOFA score,serum IL-6,oxygenate index,serum creatinine and mean arterial pressure improved insignificantly in patients with phase Ⅲ of AKI(P ＞0.05),but those were improved significantly in patients with phases Ⅰand Ⅱ of AKI(P ＜ 0.05),while serum IL-6 in patients with phase Ⅱ of AKI was still higher than that in patients with phase Ⅰ of AKI(P ＜ 0.01).Conclusions Therapeutic effect of PD on children with AKI following CPB is better if PD is started in the phases Ⅰ and Ⅱ of AKI,especially in the phase Ⅰ of AKI.The RIFLE criteria and IL-6 are useful guidance to the assessment of patients' illness.

Objective To detect anti-M3 receptor antibodies in primary Sj(o)gren's syndrome(pSS)patients and to explore its association with clinical manifestations.Methods Anti-M3 antibodies were tested in 70 patients with pSS,50 patients with systemic lupus erythematosus(SLE)and 76 normal controls with ELISA and Western blot.The correlation between anti-M3 antibodies and other clinical manifestations was analyzed.Results (1)The positive rate of anti-M3 antibodies in pSS Was 47.14% using ELISA and 60.00% using Western blot in SLE 4.00% using ELISA and 12.00% using Western blot and in normal controls 14.47% using ELISA and 15.79% using Western blot.(2)The incidence of sehirmer test,tear break-up time(BUT),whole saliva flow rate,punctate epithelial erosions(PEE)on the corneas and external eye examination were not significantly different between the anti-M3 positive and negative groups.(3)The incidences of IgG,rheumatoid factor,SSB and fluorescence index(FI)＞3 were higher in the positive group than in the negative group using EUSA.Conclusion The positive rate of anti-M3 antibodies is higher in pSS than in SLE and normal controls and in some degree it has correlation with the lesion in salivary gland.

Objective To observe myocardial tolerance to ischemia/reperfusion (I/R) injury in rats after exposure to X-ray irradiation.Methods Twelve male rats were randomly divided into control group and radiation group.The rat model of radiation-induced heart disease was established in the radiation group by precordial irradiation with 20.0 Gy of 6 MV X-ray in a single fraction.At 14 days after model establishment,the Langendorff perfusion technique was performed in the two groups and the cardiac parameters including left ventricular developing pressure (LVDP),left ventricular end diastolic pressure (LVEDP),maximal rate of left ventricular pressure rise/fall (+/-LVdp/dtmax),and coronary flow (CF)were recorded.Myocardial infarct size after I/R was compared between the two groups by 2,3,5-triphenyltetrazolium chloride staining.Results After 30 minutes of ischemia and 60 minutes of reperfusion,the irradiation group had a significantly slower CF than the control group (5.64±0.35 vs.8.38±0.52 ml/min,P=0.002).Moreover,the irradiation group had substantially poorer recovery of cardiac function in isolated hearts compared with the control group,as shown by a significantly reduced LVDP (25.4±2.31 vs.52.76±2.76 mm Hg(1 mm Hg=0.133 kPa),P=0.000),significantly reduced+/-LVdp/dtmax(547.04±78.74 vs.1 100.05±83.35 mm Hg(1 mm Hg=0.133 kPa)/s,P=0.001;-408.81±56.74 vs-813.62±73.82mm Hg(1 mm Hg =0.133 kPa)/s,P=0.002),and a significantly increased LVEDP (85.29±4.61 vs.65.65±3.65 mm Hg (1 mm Hg =0.133 kPa),P=0.012).X-ray irradiation induced a significantly increased percentage of myocardial infarct size in rats (44.67％±0.95％ vs.30.46％±0.96％,P=0.000).Conclusions X-ray irradiation can induce coronary injury,reduce myocardial tolerance to I/R injury,and increase myocardial infarct size after I/R in rats.
