RESUMEN
Objective:To explore the differences of the resting-state functional connectivity(FC) between goal-directed network and habituation networks in patients with early- and late-onset obsessive compulsive disorder (OCD) and the correlation between the strength of FC in the differential brain regions and cognitive flexibility.Methods:From October 2019 to April 2021, 40 patients with OCD were included in this study, including 22 patients with early-onset OCD and 18 patients with late-onset OCD.The cognitive flexibility of all subjects was assessed using the Wisconsin card sorting test (WCST), the Stroop task and the trail making test (TMT). The brain regions which were associated with goal-directed network(caudate, orbitofrontal cortex, ventromedial prefrontal cortex, and anterior cingulate cortex) and the brain regions which were associated with habituation network(putamen, supplementary motor area and insula) were selected as FC regions of interest (ROI). The DPABI and SPM12 plug-ins in the matlab2011a platform were used for whole brain FC analysis to compare the difference of FC between patients with early-onset OCD and patients with late-onset OCD on the two networks.The data were analyzed by SPSS 25.0 with χ2 test, independent samples t-test, and Pearson correlation analysis. Results:Compared with patients with early-onset OCD, patients with late-onset OCD had significantly enhanced FC of the left supplementary motor area with the left putamen and left insula.The total number of persistent errors of WCST in patients with late-onset OCD was greater than that in patients with early-onset OCD ((20.61±11.30), (14.95±8.94), P<0.05). The FC of the left putamen-left supplementary motor area was significantly and positively correlated with the total number of sustained responses ( r=0.678, P=0.003) and the total number of incorrect responses ( r=0.590, P=0.013) in patients with late-onset OCD.The FC of the left supplementary motor area-left insula was significantly positively correlated with the number of responses required to complete the first classification in patients with late-onset OCD ( r=0.485, P=0.049). Conclusion:Patients with late-onset OCD have stronger habituation network FC than patients with early-onset OCD, and the enhanced FC correlates with patients' cognitive flexibility performance, while late-onset OCD has more impaired cognitive flexibility than early-onset OCD.
RESUMEN
Giant hypertrophy of gastric mucosa is rare and lack of typical clinical manifestations. The main treatment measures were minimally invasive surgery and drug intervention. Clinicians should pay attention to it's imaging features, in order to make early diagnosis and treatment, and obtain a good prognosis. The authors introduce the results of gastro-enterography and computed tomography in a case with giant hypertrophy of gastric mucosa, and differentiate the imaging results from gastric cancer, lymphoma and gastric stromal tumor, so as to provide references for the clinical diagnosis of the disease.
RESUMEN
Objective To investigate the difference of Theory of Mind (ToM) processing (especially in social-perceptual component and social-cognitive component) in male methamphetamine (METH) addicts, and test whether the deficits of ToM is correlated with their psychotic symptoms or not. Methods Thirty METH addicts with psychotic symptoms (METH-P group), 31 METH addicts with no psychotic symptoms (METH-NP group) and 41 healthy controls (control group) were recruited. Eyes Task and Faux pas Task were used to test the social-perceptual component and social-cognitive component in all participants. The psychotic symptoms of METH addicts were assessed using Brief Psychiatric Rating Scale (BPRS). Results Compared with control group, performance was poor in Eyes Task and Faux pas Questions in both METH-P group and METH-NP group (P＜0.05). Performance in Eyes Task was poorer in METH-P group than in METH-NP group (P＜0.05). There were no significant differences in performance in Faux pas Questions scores between METH-P group and METH-NP group (P＞0.05). Multivariate linear regression analysis demonstrated that BPRS positive symptom score were correlated with Eyes Task scores of METH addicts (β=-0.415, P=0.001). Conclusions METH addicts exhibit deficits in both ToM social-perceptual component and ToM social-cognitive component. METH-associated psychosis are related to the deficit in social-perceptual component of ToM.
RESUMEN
ObjectiveTo investigate the effect of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) on liver function and treatment outcome in patients with pancreaticobiliary diseases. MethodsA total of 397 patients with pancreaticobiliary diseases who underwent ERCP with an electronic duodenoscope in Beijing Chuiyangliu Hospital from January 2005 to July 2015, were enrolled. According to the type of disease, they were divided into benign obstruction group (109 patients), malignant obstruction group (47 patients), pancreatitis group (27 patients), foreign body obstruction group (127 patients), simple cholangitis group (19 patients), biliary fistula group (15 patients), juxta-ampullary duodenal diverticula group (29 patients), and liver transplantation group (24 patients). Liver function parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), and total bilirubin (TBil) were measured at 1 day before ERCP and at 4 weeks after ERCP. The therapeutic effect was evaluated at 1 month after ERCP. The paired t-test was used for comparison of continuous data before and after treatment within one group, an analysis of variance was used for comparison between multiple groups, and the chi-square test was used for comparison of categorical data between groups. ResultsAfter ERCP, all the patients showed significant improvements in ALT, AST, ALP, GGT, and TBil, suggesting that ERCP significantly improved the subjects′ liver function (all P＜0.05). The evaluation of therapeutic effect showed that after ERCP, all the groups showed significant remission of symptoms; all the patients in the simple cholangitis group were cured, while those in the liver transplantation group and malignant obstruction group only achieved certain improvements. ConclusionTherapeutic ERCP can significantly improve the patients′ liver function. However, as for patients with liver transplantation and pancreaticobiliary tumors, laparoscopic surgery should be performed in combination with ERCP.

Objective To explore the technological and therapeutic value of endoscope for removal of hepatobiliary necrosis after liver transplantation.Methods Data of 36 patients with suspected hepatobiliary diseases,who underwent choledochoscopy or duodenoscopy to remove necrosis after liver transplantation,were reviewed.Liver function before and after the treatment were compared.Results Hepatobiliary necrosis located in common bile duct (n =6),intrahepatic bile duct (hilar bile duct included) (n =24) and intraand extra-hepatic duct (n =6).The total success rate was 72.2％ (26/36).Full clearance of bile duct necrosis was accomplished in 16 patients,partial clearance in 15 patients and the necrosis could not be removed in 5 others.The serum bilirubin and transaminase decreased significantly,compared with those before endoscopic treatment (P ＜ 0.05).No serious complications or death related to endoscopy occurred during the treatment.After 6-84 month follow-up,in 17 survivals,3 patients underwent a second liver transplantation with good prognosis.All the survivals had a life of good quality with no placed drainage tube except for one with drainage tube for four years with unstable serum bilirubin.Nineteen patients died from biliary tract related complications or other diseases during the long-term follow-up,among which eleven patients survived beyond four years.Conclusion Endoscopy for hepatobiliary necrosis removal,a minimally invasive method,is effective and safe.
RESUMEN
Objective To evaluate the effect of evidence- based nursing for patients receiving percutaneous coronary intervention and stent implantation. Methods A total of 136 patients with coronary heart disease were randomly divided into the intervention group (n = 68) and the control group (n = 68). Traditional nursing measures were employed for the patients of the control group , while evidence-based nursing intervention was adopted for the patients of the intervention group. The patient’s comfortableness, satisfaction and the occurrence of complications were determined at 24, 48 and 72 hours after the operation, and the results were compared between the two groups. Results At 24, 48 and 72 h after percutaneous coronary intervention, the each dimension score of GCQ and the total score of the intervention group were significantly higher than those of the control group (P<0.05). The occurrence of back pain, urinary retention and hypotension in the intervention group was significantly lower than those of the control group (P < 0.05). Patient’s satisfaction extent of the intervention group was significantly better than that of the control group (P < 0.05). Conclusion Evidence-based nursing intervention can effectively enhance the nursing skill and orientation, and reduce the occurrence of back pain, urinary retention and hypotension, thus improve patient’s comfortableness and satisfaction. Therefore, evidence - based nursing intervention should be recommended in clinical practice.
RESUMEN
Objective To evaluate the feasibility, advantages and pitfalls of trans-gastric, trans-colonic and trans-umbilical peritoneoscopy, and to compare pure natural orifice transluminal endoscopic surgery (NOTES) with hybrid NOTES. Methods Two female pigs of 30kg were used in the study, one for pure NOTES, the other for hybrid NOTES. Each pig received trans-gastric, trans-colonic and trans-umbilical peritoneoscopy, respectively, followed by postmortem examination for organic lesions and closure of incisions.The two approaches were compared in terms of intra-operative situation and manipulation. Results The vital signs of the pigs were stable during the procedures, with no peri-incision organic lesions. There were blind areas in trans-gastric as well as in trans-colonic peritoneoscopy. It was easier to close the colonic incision than the gastric one. The situation in trans-umbilical peritoneoscopy was similar to laparoscopic surgery. Hybrid NOTES seemed superior to pure NOTES with regard to safe access, stable pneumo-peritoneum and adequate visualization. Conclusion Three routes for NOTES appear to be reasonable and feasible. Hybrid NOTES is more effective and safer than pure NOTES with current instruments.
RESUMEN
Objective To investigate the clinical value of argon plasma coagulation (APC)trans-choledochoscopy in biliary tract complications following liver transplantation. Methods All 27 patients underwent T-tube-choledochoscopy or percutaneous transhepatic cholangioscope (PTCS).APC was used to burn the hyperplasia of bile duct stenosis and then expended the stenosis with bougienage. The bile duct foreign bodies were burnt by APC and then eliminated. The granulation tissues of bile duct were burnt by APC after biopsied. The sutures of anastomoses were burnt by APC and then eliminated. Results In general, the therapeutic achievement ratio of stenosis of bile duct in 25 cases of 28 locations was 78. 6% (22/28). The clearance ratio of bile duct foreign bodies was 85. 7% (6/7). The elimination ratio of granulation tissues was 100% (5/5), the same as the elimination ratio of sutures of anastomoses. There were no treatment-related complications about APC. The recurrence ratio of bile duct stenosis was respectively 4.5% (1/22) and 13. 6% (3/22)after follow-up for 3 and 6 months respectively. All the recurrent stenosis was non-anastomotic. The recurrence ratio of bile duct foreign bodies was respectively 16. 7% (1/6) and 33.3% (2/6) after follow-up for 3 and 6 months respectively. Conclusion APC trans-choledochoscopy in treatment of biliary anastomotic stenosis, mural foreign bodies, mural biliary cast, granulation tissues of bile duct and sutures of anastomoses following liver transplantion has a high success ratio and a sure long-term efficacy without treatment-related complications.
RESUMEN
Disasters are traumatic events that are always incongruent with our existing cognitive structures. Immediate negative psychological impact and traumatic related psychiatric disorders are popular among survivals involving the disasters. Super-half of survivals involving the "5" 12" Wenchuan earthquake experienced the symptoms of anxiety or increased arousal. 12.59% of survivals were met with the ASD diagnosis. 21.29% of adults and 10.21% of adolescents were met with the PTSD diagnosis 5 months after the major earthquake. Immediately negative psychological impact and high prevalence of traumatic related psychiatric disorders among survivals were confirmed.More effort should be paid on the disaster related patients in emergency department with psychiatric issues. Also, the long-term psychological service is necessary for Sichuan Pest-Disaster Reconstruction Projects.
RESUMEN
Background The disability of theory of mind (ToM) has been confirmed in chronic or acute medicated schizophrenic patients.The role of ToM ability in first-episode, drug-naive schizophrenic patients was investigated in this study.Methods ToM was assessed with the Eyes task and Faux pas task in first-episode, drug-naive schizophrenic patients( n =52)compared with healthy controls ( n =64). Verbal Fluency Test (VFT) and Digit Span Test (DST) were also examined in two groups. Psychiatric symptoms were evaluated by the Positive and Negative Syndrome Scale (PANSS).Results The tests that involved the ToM ability (I. E. Mind reading and Faux pas questions) were impaired in the schizophrenic group. The schizophrenia performed worse than the normal controls on the VFT. The schizophrenic negative subgroup performed worse than the positive subgroup in Mind reading and VFT. There was a significantly positive correlation between the performances of the tests that involved the ToM ability and the scores of VFT in schizophrenic patients. There was a significantly negative correlation between the performances of the tests that involved the ToM ability and negative symptom scores in the patients.Conclusions The patients with schizophrenia exhibit ToM deficit that is probably associated with the frontal lobe dysfunction.The performance of ToM dysfunction might be different between negative subjects and positive ones.
RESUMEN
Myasthenia gravis is an autoimmune disease resulting from the production of antibodies against acetylcholine receptors of the endplate. These antibodies impair postjunctional membrane and reduce the number of functional acetylcholine receptors of endplate. Thymectomy is an effective therapeutic method for adult myasthenic patients. In this paper, the author reviewed the pathophysiological characteristics and problems related to anesthesia, such as preoperative evaluation, the effect of preoperative medical treatment on the anesthesia, patients'response to muscle relaxants and postoperative management.

RESUMEN
Objective To investigate the characteristics of the pharmacodynamics of rocuronium bromide in patients with hepatobiliary disease. Methods Forty-eight patients undergoing abdominal surgery were divided into four groups, group A: patients with liver cirrhosis and portal hypertension (n = 12); group B1 : patients with cholelithiasis and obstructive jaundice (n = 12); group B2 : patients with cholelithiasis but no obstructive jaundice ( n=12);group C: patients without hepatobiliary disease ( n = 12) . Their renal function was normal. Patients with cardiovascular and neurological diseases were excluded. Premedication consisted of intramuscular phenobarbital 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with midazolam 0.05 mg?kg-1 , fentanyl 2?g?kg-1 , propofol 2 mg?kg-1 and rocuronium 0.6 mg?kg-1 . The patients were intubated and mechanically ventilated. PETCO2 was maintained at 30-35 mm Hg. Anesthesia was maintained with iv infusion of propofol and fentanyl. Additional bolus dose of rocuronium 0.15 mg?kg-1 was given when T, recovered to 25% and each patient received six additional doses irrespective of duration of operation. Neuromuscular function was monitored using Datex-Ohmeda NMT mechanosensor. Onset time (from the end of injection to maximum depression of muscle twitch), clinical duration of intubating and additional dose (25 % recovery of T1 ) and recovery index (T1 from 25 % -75 %) were recorded. Results The demographic data were comparable among the four groups. The onset time was significantly longer in group A than that in group B, , B2 and C ( P
