RESUMO
The hemodynamics of children with congenital heart disease (CHD) often changes during the perioperative period. Unfortunately, the evaluation of cardiac function in children with CHD is mainly focused on the left ventricle. With the further understanding of cardiac hemodynamics, the monitoring of RV function has gradually become an important part of cardiac intensive care department. We totally searched five databases including Pubmed, Embase, Cochrane, Wanfang Med, as well as China National Knowledge Infrastructure (CNKI) and reviewed the clinical research progress of the application of TAPSE in the evaluation of RV systolic function in children with CHD to provide a theoretical basic for the monitoring of RV function before and after operation in children with CHD.
RESUMO
Objective To investigate the effect of butylphthalide and sodium chloride injection on patients who received endovascular treatment for acute anterior circulation large vessel occlusive stroke.Methods A total of 173 patients were identified from February 2015 to December 2017 in the Department of Neurology of Jingling Hospital in this retrospective observational study.Propensity score-matching analysis was performed to balance differences in baseline characteristics between patients who received butylphthalide injection (butylphthalide group) and those who did not (control group).The modified Rankin Scale scores at 90 days were compared between the butylphthalide and control groups.Results A total of 144 patients who received endovascular treatment for acute anterior circulation large vessel occlusive stroke were finally analyzed,54 cases in the butylphthalide group and 90 cases in the control group.The proportion of good functional outcome at 90 days in the butylphthalide group was higher than that in the control group (63.0％ (34/54) vs 44.4％ (40/90);x2=4.633,P=0.031).Thirty-six pairs were matched successfully by the propensity score matching,36 patients in the butylphthalide group and 36 in the control group.There was no statistically significant difference in the 90-day functional outcome between the two groups (66.7％ (24/36) vs 44.4％ (16/36);x2=3.600,P=0.058).One hundred and fifteen patients were recanalized,47 cases in the butylphthalide group and 68 cases in the control group,and after the propensity score matching,30 pairs were analyzed.The proportion of good functional outcome at 90 days in the butylphthalide group was higher than that in the control group (73.3％ (22/30) vs 46.7％ (14/30);x2=4.444,P=0.035).Conclusion After propensity score-matching,butylphthalide and sodium chloride injection could improve 90-day functional outcome in patients with acute anterior circulation large vessel occlusive stroke and obtained recanalization by endovascular treatment while could not before propensity score-matching.
RESUMO
Objective To investigate the clinical features, diagnosis and management of pancreatic lesions in patients with von Hippel-Lindau (VHL) disease, and improve the current understanding on pancreatic lesions in VHL disease.Methods The clinical data of three VHL disease patients with pancreatic lesions were analyzed retrospectively, including clinical features, laboratory findings, imaging, pathological features, operation method and follow-up.Results Two patients had a family history of hemangioblastoma in central neural system, and 1 patient had retinal multiple angioma and angioma in central neural system, who were diagnosed as VHL.One patient with pancreatic portal hypertension had splenectomy and biopsy of left renal tumor.During the surgery, pancreatic cystic lesions were observed and the transparent cysts were diffusively distributed on the surface.The other 2 patients were diagnosed as pancreatic multiple cysts and non functional pNETs, and pancreatic multiple cysts, respectively, based on the imaging.All the three patients had stable disease status, and followed up by outpatient visits.Conclusions VHL disease can manifest as simple pancreatic cyst, pancreatic serous cystadenoma and pNETs.The optimal individualized treatment should be determined by Multidisciplinary team (MDT) according to the general condition of patient.
RESUMO
Objective To investigate the impact of laparoscopic gastrointestinal surgery on serum protein expression in patients with type 2 diabetes mellitus(T2DM).Methods Twelve patients with T2DM received gastrointestinal surgery at Changhai Hospital of the Second Medical University from June 2008 to September 2010.Their serum samples were collected at different time points(before surgery,1 week and 1 month after surgery).Total proteins were seperated by two-dimensional(2D)gel electrophoresis.The differentially expressed proteins were analyzed by mass spectrometry and bioinformatics.Results Protein extracts of the serum samples were separated on 2D gels successfully.Twenty differentially expressed proteins in the serum after surgery were screened out.Eight proteins were successfully identified,in which the expression of 5 proteins(Rho GDP-dissociation inhibitor 1,Prohibitin,Alpha-1-anfitrypsin precursor,Serotransferrin precursor and Fibrinogen gamma chain precursor)was increased after operation,and the expression of 3 proteins(MAP3K12-binding inhibitory protein 1,Coronin-1A and Isovalery1-COA dehydrogenase) was decreased.Conclusions The expression of 20 proteins have been changed significantly in serum samples after laparoscopic gastrointestinal surgery in patients with T2DM,and 8 proteins were successfully identified.
RESUMO
Objective To investigate the mechanism of gastric bypass surgery in the treatment of type 2 diabetes mellitus in a rat model. Methods Seventy-two 8-week-old GK rats were randomly divided into operation group, sham operation group, diet control group and control group (18 rats in each group) according to the random number table. Rats in the operation group and the sham operation group received gastric bypass surgery and transection and reanastomosis of the gastrointestinal tract, respectively. The food intake was set as 15 g/d for each rat in the diet control group, while rats in the control group were fed ad libitum. The levels of fasting blood glucose ( FBG), postprandial blood glucose (PPBG) and glucagon-like peptide-1 (GLP-1) were detected before operation and at postoperative week 2, 4 and 8. The levels of PPBG and GLP-1 were detected at postoperative week 2, 4 and 8, then 6 rats of each group were sacrificed to detect the apoptosis of islet B cells using the TUNEL method. All data were analyzed using the t test. Results In the operation group, the preoperative levels of FBG and PPBG were (16.2±0.8)mmol/L and (31.1 ± 1. L)mmol/L, respectively, which were significantly higher than (9.2± 0.6) mmol/L and (13.1 ±0.7) mmol/L at 4 weeks after the operation, and (9. 7 ± 0. 7) mmol/L and (12. 3 ± 0.7) mmol/L at 8 weeks after the operation (t = 20. 7, 49. 7; 18. 8, 39. 0, P < 0.05 ). The levels of FBG and PPBG before the operation and at 4 and 8 weeks after the operation in the operation group were significantly lower than those in the sham operation group, diet control group and control group at corresponding time points (t = 27.7, -57.8; 11.3, -59.9; -27.4, -48.2; -13.2, -52.7; -7.0, -24.9; -18.2, -56.4, P<0.05). In the operation group, the levels of fasting GLP-1 and postprandial GLP-1 were ( 10. 7 ± 1. 0) pmol/L and (42.5 ±1.2)pmol/L, respectively, which were significantly lower than (26. 1 ±0.9)pmol/L and (90.7 ± 1.7)pmol/L at4 weeks after the operation, and (25.3 ± 1.2)pmol/L and (90.4 ±2.0)pmol/L at 8 weeks after the operation (t=42.1, -92.4; -29.1, -72.7, P <0.05). The levels of fasting GLP-1 and postprandial GLP-1 before the operation and at 4 and 8 weeks after the peration in the operation group were significantly higher than those in the sham operation group, diet control group and control group at corresponding time points (t = 48.0, 61.9; 38.0, 62.2; 50.9, 65.2; 37.0, 48. 1; 27.5, 51.6; 17.5, 52.9, P<0.05). The number of the apoptotic islet β cells in the operation group was decreased with time. The apoptosis rates in the operation group, sham operation group, diet control group and control group were 5.9%±0.7% , 47.2%± 1.0% , 21. 1%± 1. 2% , 46.5%±1.4% at 4 weeks after the operation, and 6.3%±1. 1% , 47.2%±1.0% , 21.2%±1.2% and 46.0% ± 1.4% at 8 weeks after the operation. The apoptosis rates in the operation group were significantly lower than those in the sham operation group, diet control group and control group at corresponding time points (t = -82. 2, - 67. 0; - 27. 1, - 22. 4; - 55. 2, - 54. 6, P < 0.05). Conclusion After gastric bypass surgery, the level of blood glucose reduces and the level of GLP-1 increases which significantly inhibit the apoptosis of islet B cells in rats with type 2 diabetes mellitus.
RESUMO
Objective To investigate the efficacy of gastric bypass surgery for the treatment of nonobese type 2 diabetes mellitus. Methods From November 2008 to August 2009, 40 patients with gastric diseases and nonobese type 2 diabetes mellitus were admitted to the Changhai Hospital, and their clinical data were prospectively studied. All patients were randomly divided into 4 groups; 10 patients received Billroth I distal gastrectomy +gastroduodenal anastomosis (BⅠ group) , 10 received proximal gastrectomy + remanant gastric esophageal anastomosis ( PG group), 10 received total gastrectomy + esophagoduodenal Y-anastomosis ( RY group) and 10received subtotal gastrectomy Billroth Ⅱ gastro-jejunostomy (BⅡ group). The length of hospital stay, pre- and postoperative body mass indexes (BMIs) , waist circumferences, levels of fasting blood glucose (FBG) , glycated hemoglobin ( GHbA1) , fasting serum insulin (FSI) and fasting C-peptide (FCP) of patients in the 4 groups were compared. All data were analyzed using analysis of variance, LSD-t test, paired t test or chi-square test. Results The clinical effects of the 4 different operative procedures on the gastric diseases were similar. The levels of FBG were (8.0 ±2.9)mmol/L before operation and (5.9 ±0.7)mmol/L after operation in the RY group, with a significant difference (t = 2. 342, P < 0. 05). The preoperative level of GHbA1 in the RY group was 7.7% ± 1.1%, which was significantly higher than 6. 9% ± 0. 6% at 2 months after the operation and 6. 1 % ± 0. 4% at 6 months after the operation (t = 4. 920, 3.012, P < 0.05). The preoperative level of FCP in the RY group was (1.30 ±0.54) μg/L, which was significantly lower than (1.95 ± 0.86) μg/L at 2 months after the operation and (2.18 ± 0.63)μg/L at 6 months after the operation (t =6. 063, 4. 651, P < 0.05). The levels of FSI in the RY group at postoperative month 1, 2 and 6 were (18 ±5) , (19 ±3) , (21 ±3) mU/L, which were significantly higher than the level of FSI [(11 ±4) mU/L]before operation (t =3. 158, 4. 502, 7. 517, P <0. 05). Preoperative levels of FBG, GHbA1, FSI and FCP in the B Ⅱ group were (8. 3 ± 1. 3) mmol/L, 7. 7% ±0. 9% , (13±4)mU/L and (1.34±0.48) μg/L, which were ignificantly different from (6.7 ± 1.2)mmol/L, 6.8%± 0.8%, (18±4)mU/L and ( 1.68 ±0.46) μg/L at postoperative month 1, (6.4 ± 1.3)mmol/L, 6.3% ±0.6% ,(18±4)mU/L and (1. 96 ± 0. 67) μg/L at postoperative month 2, and (5. 6 ±0. 7) mmol/L, 6.0%±0.3%, (19 ± 4) mU/L and (2.27 ± 0. 59) |μg/L at postoperative month 6 (t = 2. 468, 2. 598, 6. 028; 3. 055, 4. 586,4.572; 3.618, 5.860, 8.577; 2.300, 3.511, 3.943, P<0.05). The levels of FBG,GHbA1 and FCP in the 4 groups at 2 months after surgery were significantly different from those at 6 months after surgery (F = 4. 699,14. 378; 7.411, 29. 192; 3. 335, 9. 334, P < 0.05). The levels of FSI in the 4 groups at different time points were significantly different (F =2. 896, 7. 012, 11. 998, P < 0.05). Conclusion The efficacy of gastric bypass surgery for the treatment of nonobese type 2 diabetes mellitus is satisfactory.
RESUMO
Objective To investigate the efficacy of transorally inserted anvil system(OrVilTM)in esophagogastrostomy and esophagojejunostomy after laparoscopic gastrectomy.Methods The clinical data of 34 patients with gastric neoplasms who were installed OrVilTM for esophagogastrostomy or esophagojejunostomy at the Changhai Hospital from July 2009 to February 2011 were retrospectively analyzed.After radical dissection of lymph nodes and full mobilization of esophagus,the esophagus was transected and the anvil was then transorally inserted into the esophagus by using the OrVilTB system.Double-stapling esophagogastrustomy or esophagojejunostomy with a circular stapler Was performed intracorporeally under direct laparuscopic view.Results The surgery was success fully completed in all the 34 patients with no conversion to open surgery.Two patients had difficulty in placing OrVilTM system.and the condition Was alleviated by reducing tension in the cuff and tilting the head back.The mean operation time,volume of blood loss,duration of postoperative hospital stay and time to gastrointestinal function recovery were 175 minutes(range,90-240 minutes),196 ml(range,50-800 ml),7.6 days(range,5-14 days)and 3 days(range,2-6 days).No postoperative anastomotic leakage Was detected.Thirty-three patients were followed up for 2-20 months with a mean time of(10±6)months,and no tumor recurrence or metastasis occurred.Conclusion OrVilTM system changes insert direction of the anvil,which significantly reduces the difficulty of laparoscopic operation,shortens the operation time and avoids the thoracotomy.
RESUMO
Objective To evaluate the feasibility of getting retroperitoneal lymph node biopsy via technique of natural orifice transluminal endoscopic surgery(NOTES)in human being with current available devices.Methods We performed trans-gastric endoscopic biopsy of retroperitoneal lymph node with the aid of laparoscopy in a 50-year-old man,who presented with abdominal pain and enlarged retroperitoneal lymph nodes and signed a written informed consent before the procedure.After routine anesthesia and abdominal skin sterilization,a pneumoperitoneum was induced with a Veress needle placed in the umbilical area,followed by the introduction of a 5-mm trocar.Gastral cavity Was sterilized with antibiotics and povidone iodine.Under laparoscopie optical control,we made a styliform incision in the anterior wall of gastric corpus with a needle knife,and enlarged the incision by a dilatation balloon and then entered the peritoneal cavity with a sterile endoscope.We got two biopsies from the enlarged lymph node with a heat forceps assisted by laparoscopy.The specimen was taken out by retrieval basket through the stomach.The gastric incision Was closed with metal clips.Results The biopsy by means of NOTES was successfully performed without intra-or postoperative complications.The diagnosis was confirmed as lymphoma pathologically.The patient received chemotherapy and was discharged on the sixth postoperative day.There was no short or long-term complication.Conclusion Transgastric access for laparoscopy-assisted biopsy of retroperitoneal lymph node is feasible and safe in human being.
