RESUMO
Objective:To investigate the effects of sedatives on the activity of the diaphragm assessed by ultrasound and the timing of extubation in elderly patients after elective surgery.Methods:All 60 eligible elderly patients were randomly divided into three groups: the propofol group, the midazolam group and the control group(n=20, each group). Remifentanil was used in the three groups to keep the Critical Care Pain Observation Tool(CPOT)score less than 3.Patients in the propofol and midazolam groups were given propofol and midazolam sedation respectively, and the Richmond Agitation Sedation Scale(RASS)score was maintained at -2.Diaphragmatic activity was measured, the time from the end of the operation to extubation was recorded, and delirium was evaluated, and the above results were compared with those of the control group, which did not receive sedatives.Results:The activity of the diaphragm was lower in the propofol and midazolam groups than in the control group[(1.10±0.12)cm, (1.17±0.30)cm vs.(1.63±0.25)cm, F=30.170, P=0.000], and there was no significant difference between the propofol group and the midazolam group( t=25.340, P=0.615). There was no significant difference in duration of extubation among the propofol, midazolam and control groups[(1.41±2.08)d, (1.25±1.53)d vs.(1.19±1.40)d, F=0.089, P=0.915]. The incidence of delirium was higher in the midazolam group than in the propofol and control groups[55.0%(11/20), 20.0%(4/20) vs.15.0%(3/20), χ2=5.230, P=0.022, χ2=7.030, P=0.008)], but the difference between the propofol group and control group was not statistically significant( χ2=0.170, P=0.677). Conclusions:The application of sedatives after elective surgery has an effect on the activity of the diaphragm in elderly patients, and the effects of propofol and midazolam are similar.However, propofol and midazolam have no influence on the duration of extubation in elderly patients after elective surgery.Compared with propofol, midazolam increases the incidence of delirium in elderly patients after elective surgery.
RESUMO
Objective To explore the clinical characteristics and related background diseases of type 1 gastric neuroendocrine tumor (g-NET) and to provide reference information for clinical diagnosis and treatment.Methods From Januayy 2011 to February 2019,at the First Affiliated Hospital of Sun Yat-sen University and China-Japan Friendship Hospital,the clinical features and related background diseases of type 1 g-NET patients (41 cases and 93 cases respectively)were retrospectively analyzed.The clinical symptoms,serological indicators,gastroscopic and pathological features,tumor location,metastasis and treatment,and concomitant diseases were statistically described.Results Among 134 patients with type 1 g-NET,there were 53 males (39.6%) and 81 females (60.4 %);and the mean diagnosed age was (51 ± 11) years (21 to 76 years).Main clinical manifestations were non-specific gastrointestinal symptoms.The mean level of serum chromogranin A was (237.7 ± 176.8) μg/L.The endoscopic findings of 97.8% (131/134) of the patients were polypoid or protuberant lesions at gastric fundus or gastric body.And 75.0% (96/128) of the patients had multiple tumors.65.7% (88/134) of the patients had the tumors with the maximum diameter less than 1 cm (77.2%,88/114) and the lesions mainly located in mucosa (59.8%,52/87) and submucosa (40.2%,35/87).The pathological classification of 79.3% (96/121) of the tumors was G1 grade and 20.7% (25/121) were G2 grade.The rate of local lymph node metastasis was 1.4% (1/73) and no distant metastasis was found.About 70.9% (95/134) of the patients received endoscopic treatment.Among the patients,93.6% (103/110) of the patients had chronic atrophic gastritis confirmed by endoscopy or pathology,45.6% (47/103) were confirmed by both endoscopy and pathology.Among the patients with chronic atrophy gastritis,serum gastrin levels of 93.2% (96/103) patients were twice higher than the upper limit of the normal value.The positive rates of antiparietal cells antibody (PCA) and intrinsic factor (IFA) were 78.5% (73/93) and 51.9% (14/27),respectively.The incidence of Helicobacter pylori (H.pylori) infection was 28.1% (16/57).The incidence of autoimmune atrophy gastritis was 80.6% (75/93).The percentage of patients with deficiency of serum vitamin B12 and ferritin was 70.8% (63/89) and 30.7% (27/88),respectively.Patients with anemia accounted for 27.8% (25/90).The patients with microcytic anemia,normocyticanemia and macrocytic anemia were 28.0% (7/25),56.0% (14/25) and 16.0% (4/25),respectively.46.9% (45/96) of the patients had increased thyroid autoantibodies and 17.9% (17/95) patients had changes of thyroid hormone level.Conclusions Type 1 g-NET is more common in women and mainly caused by autoimmune atrophic gastritis.The level of serum PCA and IFA increase in more than half of the patients.And it is often accompanied by vitamin B12 deficiency and autoimmune thyroid disease.
RESUMO
<p><b>OBJECTIVE</b>To explore the primary site and pathological feature of neuroendocrine neoplasm (NEN), especially the NEN of digestive system.</p><p><b>METHODS</b>Clinicopathological data of NEN patients at China-Japan Friendship Hospital from January 2012 to December 2016 were retrospectively analyzed. Tumor primary sites were summarized. Association between tumor site and pathological grading in gastroenteropancreatic neuroendocrine neoplasm(GEP-NEN) was examined.</p><p><b>RESULTS</b>There were a total of 903 cases of NEN. Sites of primary tumor included the digestive system in 699 cases(77.4%), the thorax(including lung, thymus and mediastinum) in 87 cases(9.6%), other sites in 60 cases (6.6%), unknown in 57 cases(6.3%). Among 699 GEP-NEN cases, the primary sites included the stomachin in 207 cases (29.6%), pancreas in 201 (28.8%), rectumin in 185 (26.5%), duodenum in 43(6.2%), jejunum and ileum in 18(2.6%), appendix in 15 (2.1%), gallbladder in 11(1.6%), esophagus in 10(1.4%), and the colon in 9 cases (1.3%). Pathologically, the tumor grading was neuroendocrine tumor (NET) G1 in 336 cases(48.1%), NET G2 in 203 cases (29.0%), neuroendocrine carcinoma (NEC) G3 in 139 cases (19.9%). All the esophagus NEN(10/10), most gallbladder NEN(9/11) and colon NEN(6/9) were poorly-differentiated NEC (G3), while all appendix NEN(15/15), most stomach NEN(147/207, 71.0%), pancreas NEN (156/201, 77.6%), rectum NEN (169/185, 91.4%), duodenum NEN (31/43, 72.1%), jejunum and ileum NEN(16/18, 88.9%) were well-differentiated NET G1 or G2.</p><p><b>CONCLUSIONS</b>The most common primary site of NEN is the digestive system. The stomach, pancreas and rectum are most common primary sitesof GEP-NEN. Difference in pathological grading is quite greatin different primary sites of GEP-NEN. Most NENs fromesophagus, colon and gallbladder are poorly-differentiated NEC.</p>
RESUMO
Objective To explore the biomechanical mechanism of non-erosive reflux disease(NERD).MethodsFrom October 4,2014 to September 30,2015,17 NERD patients and 17 healthy controls were recruited from the outpatients department of China-Japan Friendship Hospital.The cross-sectional area(CSA), intra-balloon pressure (IBP)and compliance(Δv/Δp)of each were measured by endoscopy in combination with EndoFlip.ResultsWith the increase of balloon volume,the compliance of gastroesophageal junction in NERD group was significantly higher than that of control group(P<0.01) while the cross sectional area and intra-balloon pressure were similar.Conclusions Increased compliance of the gastroesophageal junction may be involved in the pathogenesis of non-erosive reflux disease.
RESUMO
<p><b>OBJECTIVE</b>To study subtype classification of gastric neuroendocrine neoplasm (NEN) and their clinicopathological characteristics in order to provide reference for clinical practice.</p><p><b>METHODS</b>Clinicopathological data of 241 gastric NEN patients (174 cases from China-Japan Friendship Hospital and 67 cases from The First Affiliated Hospital of Sun Yat-Sen University) between January 2011 and June 2016 were retrospectively summarized. According to serum gastrin, 24-hour intragastric pH monitoring and pathological grade, patients with gastric NEN were divided into 4 types: type I( (hypergastrinemia and achlorhydria, related to autoimmune chronic atrophic gastritis), type II( [hypergastrinemia and Zollinger-Ellison syndrome, related to gastrinoma or multiple endocrine neoplasia type I( (MEN-I()], type III( (sporadic disease with normal serum gastrin level), and type IIII( [poorly differentiated gastric neuroendocrine carcinoma (NEC) and mixed adenoneuroendocrine carcinoma (MANEC)]. Clinicopathological features, treatment and prognosis of 4 types were analyzed.</p><p><b>RESULTS</b>Of 241 gastric NEN cases, there were 86 cases (35.7%) in type I(, 7 cases (2.9%) in type II(, 61 cases (25.3%) in type III( and 87 cases(36.1%) in type IIII(. Among 86 cases of type I( gastric NEN, 73 cases (84.9%) were multiple lesions,tumor size of 66 cases (76.7%) was less than 1 cm, all the 86 cases were polypoid or granular lesions. 2 cases(2.3%)presented distant metastasis, 69 cases (80.2%) had pathological grading as NET G1; most of them received endoscopic surgery treatment and follow-up; somatostatin analogs(SSA) was used in patients with multiple lesions and repeated recurrence after endoscopic treatment. Among 7 cases of type II(, 4 cases were gastrinoma, 3 cases MEN-I(; 5 cases presented distant metastasis; treatment included surgery, SSA and proton pump inhibitor (PPI) therapy. Among 61 cases of type III( gastric NEN, 49 cases(80.3%) were single lesion,tumor size of 25 cases(41.0%) was more than 2 cm, 29 cases(47.5%) had lymph node metastasis or distant metastasis; treatment included endoscopic resection, surgery or SSA therapy according to the tumor staging. Among 87 patients of type IIII( gastric NEN, 74 cases(85.0%) had single lesion,tumor size of 51 cases (58.6%) was more than 2 cm; lesions were found in gastric cardia in 35 cases (40.2%); 65 cases (74.7%) had lymph node metastasis or distant metastasis; treatment included chemotherapy, or surgery plus chemotherapy. At the end of follow-up(June 30, 2016), 58 patients were dead, including 1 case of type I(, 12 cases of type III( and 45 cases of type IIII(. The overall survival rate of all the patients was 74.2%, and was 98.8%, 100%, 79.3%, 39.2% of types I(, II(, III(, IIII( respectively. The overall survival rate between type III( and type IIII( gastric NEN was significantly different(P = 0.000).</p><p><b>CONCLUSIONS</b>Subtype classification of gastric NEN is very significant for making therapeutic decisions and prognostic evaluation. Patients of type I( or type II( gastric NEN have good prognosis,while those of type III( and type IIII( have poor prognosis, and those of type IIII( have the worst prognosis.</p>
