RESUMEN
Objective: Radiofrequency catheter ablation (RFCA) has evolved into an effective and safe technique for the treatment of tachyarrhythmia in children. Concerns about children and involved medical staff being exposed to radiation during the procedure should not be ignored. "Fluoroscopy integrated 3D mapping", a new 3D non-fluoroscopic navigation system software (CARTO Univu Module) could reduce fluoroscopy during the procedure. However, there are few studies about the use of this new technology on children. In the present study, we analyzed the impact of the CARTO Univu on procedural safety and fluoroscopy in a wide spectrum of tachyarrhythmias as compared with CARTO3 alone. Methods: The data of children with tachyarrhythmias who underwent RFCA from June 2018 to December 2021 were collected. The CARTO Univu was used for mapping and ablation in 200 cases (C3U group) [boys/girls (105/95), mean age (6.8 ± 3.7 years), mean body weight (29.4 ± 7.9â kg)], and the CARTO3 was used in 200 cases as the control group (C3 group) [male/female (103/97), mean age (7.2 ± 3.9 years), mean body weight (32.3 ± 19.0â kg)]. The arrhythmias were atrioventricular reentrant tachycardia (AVRT, n = 78), atrioventricular node reentrant tachycardia (AVNRT, n = 35), typical atrial flutter (AFL, n = 12), atrial tachycardia (AT, n = 20) and ventricular arrhythmias [VAs, premature ventricular complexes or ventricular tachycardia, n = 55]. Results: â There was no significant difference in the acute success rate, recurrence rate, and complication rate between the C3 and C3U groups [(94.5% vs. 95.0%); (6.3% vs. 5.3%); and (2.0% vs. 1.5%); P > 0.05]. â¡ The CARTO Univu reduced radiation exposure: fluoroscopy time: AVRT C3: 8.5 ± 7.2â min vs. C3U: 4.5 ± 2.9â min, P < 0.05; AVNRT C3: 10.7 ± 3.2â min vs. C3U: 4.3 ± 2.6â min, P < 0.05; AT C3: 15.7 ± 8.2â min vs. C3U: 4.5 ± 1.7â min, P < 0.05; AFL C3: 8.7 ± 3.2â min vs. C3U: 3.7 ± 2.7â min, P < 0.05; VAs C3: 7.7 ± 4.2â min vs. C3U: 3.9 ± 2.3â min, P < 0.05. Corresponding to the fluoroscopy time, the fluoroscopy dose was also reduced significantly. ⢠In the C3U group, the fluoroscopy during VAs ablation was lower than that of other arrhythmias (P < 0.05). Conclusion: The usage of the "novel image integration technology" CARTO Univu might be safe and effective in RFCA for a wide spectrum of tachyarrhythmias in children, which could significantly reduce fluoroscopy and has a more prominent advantage for VAs ablation.
RESUMEN
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.

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).

RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
