The clinical data of 26 cases with pathologically confirmed primary gastrointestinal nonHodgkin's lymphoma (PGINHL) admitted to our hospital from January 2001 to December 2010 were retrospectively analyzed.Among 26 patients,12 cases occurred in stomach,9 cases in small intestine,4 cases in colon and 1 case in multiple sites.The most common symptoms were abdominal pain (73％),followed by gastrointestinal bleeding (23％) and abdominal mass (15％).The main pathological types were MALT lymphoma (35％),diffuse large B-cell lymphoma (35％),and enteropathy-type T-cell lymphoma ( 15％ ).There were 14 patients in stage Ⅰ,6 in stage Ⅱ,1 in stage Ⅲ and 5 in stage ⅣV.Radical surgery and/or chemotherapy was the main therapy for PGINHL.

Objective To investigate the expression of VCAM-1 and E-selectin in vessel walls of the patients with thromboangiitis obliterans(TAO).Methods The vessel tissues were taken from 18 cases of amputation operation due to TAO and 16 cases of amputation operation due to non-vascular diseases.The expression of VCAM-1 and E-selectin were assessed by the immunohistochemical method.Results The positive expression rate of VCAM-1 in vessel wall of the patients with TAO was 77.8%(14/18),which of E-selectin was 72.2%(13/18);both of them were obviously higher than 6.3%(1/16) and 6.3%(1/16) in the control group.The positive rate of VCAM-1 and E-selectin had no correlation with the age,smoking amount,smoking time and drug use (P>0.05).Conclusion The expression of VCAM-1 and E-selectin have close correlation with the occurrence and development of TAO.Detecting the expression of VCAM-1 and E-selectin can serve as a diagnostic indicator of TAO.

Objective To explore the findings and clinical value of bedside ultrasonography in superior vena cava(SVC) syndrome in children after cardiac operations for congenital heart disease. Methods Bedside ultrasonography was performed on 6 children suspected of SVC syndrome after 5-38 hours[(22?11) hours] postoperatively,to view the structure and blood flow of SVC and its main branches. All the patients were reoperated as soon as diagnosed. Results Five children got severe SVC obstruction, marked with stenosis, turbulent, continuous and high velocity in SVC. Color Doppler flow imaging presented almost absence of flow due to nearly complete occlusion of the innominate vein in 1 child. Ultrasonographic diagnosis was confirmed by the reoperative findings. All the patients were cured by reoperation and discharged with normal ultrasonographic results. Conclusions Bedside ultrasonography can provide early and accurate diagnosis in children with SVC syndrome after cardiac operation.

Objective To explore the protective effect of portal vein administration of propofol on hepatic ischemia reperfusion injury(HIRI) and its mechanism.Methods Thirty-two male rabbits were randomly allocated into four groups:Group A(sham operation group),the abdomen was only opened and closed;group B,the hepatic inflow was occluded for 30 min,and reperfused for 60 min;group C,the same managment as group B + propofol injected through jugular vein;group D,the treatment same as group B + propofol injected through portal vein.Drug injection was completed 20 min before hepatic inflow occlusion.Serum ALT and AST,and endothelin-1(ET-1) and nitric oxide(NO)in the hepatic tissue and blood,and the content of ATP in hepatic tissue were determined.Results The level of ET-1 in plasma and hepatic tissue was significantly increased in group B compared to group C and D(P

Objective To Summarize the application of digital artery dorsal distal interphalangeal joint perforator flap to repair finger tip skin defect,and at the same time,the method and effect of anastomosis of finger dorsal branch of digital nerve sensory reconstruction.Methods From September 2012 to March 2015,78 patients 92 fingers were treated in Orthopedics Department of Jinshan Branch Hospital of the Sixth People′s Hospital of Shanghai,all patients with finger artery distal interphalangeal joint dorsal cutaneous branches of the dorsal flap pedicled with retrograde,transferred to repair the skin defect of finger end,and anastomosis of dorsal branch of the proper digital nerve reconstruction.Results Postoperative vascular crisis occurred in 8 cases,2 cases of partial flap necrosis and healed after symptomatic treatment.All flaps survived,the wounds healed in I stage,and the donor site healed in I stage.All the 73 cases were followed up,the follow-up period ranged from 3.0 to 12.0 months,an average of (7.8±2.5) months.The postoperative appearance and feel good,soft texture,abrasion resistance,no tenderness,cold resistance,dynamic two-point recovered to 4.0-8.0 mm,average (5.3±0.9) mm.Static two-point discrimination was 4.0-9.0 mm,average (5.8±1.2) mm.The method of TAM was used to determine the function of the 67 fingers,good for the 7 finger,but also for the 5 finger and the difference of the 0 finger.The excellent and good rate was up to 93.7%.Conclusion The operation without sacrifice of major arteries and nerves by finger,the middle finger dorsal skin for non functional surface area,and at the same time by anastomosis of dorsal branch of the proper digital nerve reconstruction,without surgery two times,is one of the ideal surgical repair of skin defect of the finger end.

Objective: To investigate the alteration of bcl- 2 gene family in the rat brain and the molecular mechanism of neuronal apoptosis following traumatic brain injury. Methods: Male Sprague -Dawley rats were subjected to lateral fluid percussion brain injury(FPI) of mo derate severity. Bcl-2, Bcl-x and Bax protein expression was detected by immun ohistochemistry. Results: (1) The immunoreactivity of Bcl-2 and Bcl-x protein decreased in the hippocampus ipsilateral impact site as early as 6 h post-injury, and this was the main cause of down-regulation of the ratio of Bcl-2+Bcl-x to Bax. (2) During 1-3 d after injury, the Bax protein express i on increased significantly, while the Bcl-2 and Bcl-x protein expression decre ased relatively slow. The decreased ratio of Bcl-2+Bcl-x to Bax was mainly due to the Bax up-regulation. Conclusion: The bcl-2 gene family is involved in neuronal apoptosis after FBI, and the protein expression alteration of the family members leads the neuronal cell to apoptosis.

Objective To explore the changes in serum and urine electrolytes of children with neurally media-ted syncope (NMS)after oral rehydration salts (ORS)[Ⅰ]treatment.Methods The study group included 135 patients [60 male and 75 female,aged 4 -16 years,average of (10.20 ±2.68)years old]with unexplained syncope and prodro-mal symptoms of syncope in our hospital between May 2014 and April 2015.The patients underwent head -up tilt test (HUTT),and completed serum electrolytes and 24 -hour urine electrolytes,and the serum electrolytes and 24 -hour u-rine electrolytes in different hemodynamic type of HUTT were compared.Positive HUTT patients were treated with health education and ORS[Ⅰ],while negative HUTT patients were received health education.Then 21 -154(42.63 ±27.71) days later,the patients returned to hospital,for the inquiry of symptom improvement,and review of HUTT,24 -hour urine and serum electrolytes.Results (1)The total effective rate of ORS[Ⅰ]treatment was 62.96% (17 /27 cases),while negative conversion rate of HUTT was 48.15% (13 /27 cases).(2)There was no significant difference in serum electro-lytes,24 -hour urine electrolytes or 24 -hour urine volume between HUTT positive group and negative group during the first visit (all P >0.05).(3)In return visit,serum calcium [(2.30 ±0.10)mmol/L vs (2.20 ±0.09)mmol/L,t =2.72,P <0.05]and serum phosphorus [(1.73 ±0.22)mmol/L vs (1.51 ±0.23)mmol/L,t =2.671,P <0.05]in HUTT positive group were significantly higher than those in negative group.The serum sodium,potassium,chloride,mag-nesium and 24 -hour urine electrolytes,24 -hour urine volume had no statistical difference(all P >0.05).(4)24 -hour urine sodium [(159.06 ±72.76)mmol/24 h vs (118.97 ±52.75)mmol/24 h,t =2.712,P <0.05],24 -hour urine chloride [(139.08 ±66.53)mmol/24 h vs (111.34 ±47.33)mmol/24 h,t =2.116,P <0.05]and 24 -hour urine volume [(1 564.21 ±829.39)mL vs (1 058.95 ±509.92)mL,t =3.371,P <0.01]after ORS[Ⅰ]treatment were sig-nificantly higher than those before ORS[Ⅰ]treatment.The serum electrolytes and 24 -hour urine potassium,calcium, phosphorus,magnesium had no statistical difference (all P >0.05).(5)There was no significant difference in serum elec-trolytes,24 -hour urine electrolytes or 24 -hour urine volume between vasovagal syncope group and postural orthostatic tachycardia syndrome group during the first visit(all P >0.05).Conclusions ORS[Ⅰ]treatment can obviously increase the 24 -hour urine sodium,24 -hour urine chloride in children with NMS.ORS[Ⅰ]is an effective therapy for NMS.

Objective To investigate the risk factors of early postoperative complications in patients undergoing pancreaticoduodenectomy. MethodsClinical data of 200 patients undergoing pancreaticoduodenectomy in our hospital from December 1999 to September 2002 were collected and analyzed retrospectively. Nine clinical factors were recruited for the study in relation to surgical complications. ResultsThe overall early postoperative complication rate was 21% (42/200). Logistic regression analysis revealed that no T tube drainage(OR=10.015), preoperative total serum bilirubin level over 171.1?mol/L(OR=7.756), preoperative diabetes (OR=4.086), end-to-end pancreaticojejunostomy (OR=2.616), intraoperative blood transfusion over 1000 ml (OR=2.410), over 65 years old (OR=2.162) were important factors for early complications. ConclusionsT tube drainage, end-to-side mucosa-to-mucosa pancreaticojejunostomy and good surgical expertise can decrease early morbidity rate.

[Objective] To optimize the conditions of the extracting process of Hujin Granules. [Methods] The orthogonal design was applied. With the total emodin and the total anthraquinone (TA) content as the parameters for the alcohol-extraction, the concentration of alcohol, the volume of solvent and the extracting time were used for optimization of alcohol-extraction. With the total polysaccharide (TP) as the parameters for water-extraction, the soaking time, the volume of water and the extracting time were used for optimization of water-extraction. [Results] The optimum conditions of alcohol-extraction were: extracting with 70% alcohol 245 mL for 2 hours and extracting twice. The optimum conditions of water-extraction were: extracting with 80 mL water (not for soaking) for 1.5 hours, extracting 3 times. [Conclusion] The results indicate that the extracting process is rational and feasible, and can provide evidence for the extracting process of Hujin Granules.
