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.

Objedtve To summarize the experience of single-stage repair of coarctation of aorta(CoA) or interrupted aortic arch (IAA)and associated intracardiac defects through median stemotomy.Methods From Jan 2007 to Jul 2008,a total of 24 pa-tients with CoA or IAA and associated intracardisc defects were surgically repaired in single-stage through median stermotomy,inchud-ing 9 coanctation of aorta,12 coarctation with aortic arch hypoplasia,and 3 interrupted aorlic arch,.The associated intracardiac de-fects were Taussing-Bing anomaly 4,non-restricted VSD 22,subaortic stenosis 1 and pulmonary vein stenosis 1.The age ranged form 1 to 99 months (average 16 months) and the body weight ranged from 4 to 19 kg(average 9.3 kg).Aortic arch reconstruction was performed by hypothermic continuous low flow bypass using regional perfusion for all patients.Three patients with LAA and 9 patients with CoA underwent end-to-end ansetomosis.Of the 12 patients with coarctation and aortic arch hyipoplasia,8 patiellts underwent ex-tended end-to-end anastomosis,2 patients underwent end-to-side anastomosis and 2 patients underwent aortoplasfy.Results 2 cases were dead. One infant with Taussig-Bing type heart was dead of severe infection after 47 days postoperative,the other one who associ-ated with LAA and VSD dead of pulmonary hypertension crisis due to pneumonia after 15 days postoperative.No patient presented neu-rdogieal complication and renal insufficiency during the perioperation.2 cases presented recurrent respiratory problem.During the 18months follow-up,no patient presented with recoarctation except one with pressure gradient more than 20 mm Hg.Conclusion Pa-tients with coarctation of aorta or interrupted aortic arch and associsted intracardisc defects should be surgically treated as early as pos-sible when diagnosis was mode.Single-stage sortic arch reconstruction through median stemotomy using continuous regional perfusion is an effective and safe procedurd.Sufficient resection of ductus,extensive dissection of thoracic vessels and optimal tissus-tissue anas-tomosis techmique are very important for successful repair and avoiding recoarctation.

[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.

Objective To explore the circadian rhythm of neurally mediated syncope (NMS)in children. Methods There were 21 6 children with NMS included in the study,including 91 male and 1 25 female,aged from 4 to 1 7 years old with a mean age of (1 1 .34 ±2.65)years,who came from the Specialist Syncope Outpatient Department or Inpatient Department of the Second Xiangya Hospital of Central South University from December 201 3 to October 201 5. The patients were divided into vasovagal syncope (VVS)group and postural tachycardia syndrome (POTS)group ac-cording to head -up tilt test (HUTT)results,including 1 78 VVS patients and 38 POTS patients.Ninety -four patients with NMS were in the <1 2 years old group[(8.88 ±1 .88)years old]and 1 22 subjects with NMS were in the ≥1 2 years old group[(1 3.24 ±1 .1 8)years old].All patients or guardians were carefully asked about the number of synco-pal attacks and the periods in which episodes occurred in before HUTT [24 hours of a day were divided into 4 periods:morning (0600 AM-1 200 AM),afternoon (1 200 AM-1 800 PM),evening (1 800 PM-2400 PM), night (0000 AM-0600 AM)].Results (1 )General data:the total syncopal episodes of 21 6 children with NMS were 61 4 episodes,including 1 78 VVS patients with 471 syncopal episodes in total and 1 43 attacks of 38 children with POTS.There were 273 episodes of 94 patients in the <1 2 years old group and 341 episodes of 1 22 subjects in the ≥1 2 years old group.There were no significant differences in the diurnal variation of syncopal episodes between the VVS group and POTS group regarding age and gender (P >0.05).(2)The number of syncopal episodes in patients with VVS which occurred in the morning hours was strikingly higher than that of afternoon,evening or nighttime (P <0.05).But there was no significant difference in the frequency of episodes in different periods through the day in the POTS group (P >0.05).Patients with VVS had a higher proportion of episodes in the morning but a lower proportion in the evening when compared with the POTS group (P <0.05).(3)The male children with NMS tended to have a higher proportion of episodes in the morning than the female patients(χ2 =1 1 .001 ,P =0.01 2).(4)There seemed to be no difference in the frequency of syncopal episodes through the day between the <1 2 years old group and the ≥1 2 years old group(χ2 =1 .995,P =0.573).Conclusions The frequency of syncopal episodes in children with VVS displayed a clear circadian rhythm,with a peak in the morning,but the POTS patients did not show a circadian variation.The male children with NMS tended to have a higher proportion of episodes in the morning than the female patients.
