Chinese Journal of Trauma 2003;0(10):-
Objective To observe the effect of hyperglycemia on intracranial pressure (ICP) and neurological outcome following severe brain injury. Methods A retrospective review was done on 79 cases with severe traumatic brain injury (with no history of diabetes or important extracranial complications) who underwent craniotomy for evacuation of intracranial hematoma and were divided into two groups based on Glasgow outcome scales (GOS) score, ie, favorable group with GOS of 5 or 4 and unfavorable group with GOS less than 3. Statistical analysis of data was accomplished by using SPSS 11.5 software. The outcome was assessed at the 6th month after injury. Results A significant correlation was found between ICP levels and admission or postoperative glucose values. The unfavorable group had significantly higher glucose levels both on admission and after operation compared with the favorable group, with statistical difference (P

Objective:To analyze the effect of anticoagulant or antiplatelet drugs on bleeding and cardio-cerebral vascular events in perioperative period of catherization for peritoneal dialysis.Methods:The clinical data of patients undergoing peritoneal dialysis catheterization in Peking University Third Hospital from July 1, 2010 to December 31, 2020 were collected and analyzed retrospectively. The patients were divided into drugs discontinuation group and drugs continuation group according to whether the anticoagulant drugs or antiplatelet drugs were discontinued or not. Baseline clinical data and bleeding and cardio-cerebral events after surgery were compared between the two groups. Multivariate logistic regression model was used to analyze the influencing factors for bleeding and cardio-cerebral events.Results:A total of 57 patients were included in the study, with 34 males and 23 females. The age was (67.37±13.93) years old (range from 27 to 97 years old). There were 37 patients in drugs discontinuation group and 20 patients in drugs continuation group. The proportions of acute myocardial infarction events in drugs continuation group were higher than those in drugs discontinuation group in 3 months and 6 months before surgery (10/20 vs 3/37, χ2=10.671, P=0.001; 11/20 vs 3/37, χ2=12.980, P<0.001 respectively). The median drugs discontinuation time was 5.0(2.0, 14.0) d (range from 1 to 30 d) before surgery, and median restore medication time was 4.0(3.0, 7.0) d (range from 1 to 14 d) after surgery in drugs discontinuation group. There was no significant difference in the proportion of bleeding (10/37 vs 8/20, χ2=1.011, P=0.315) and cardio-cerebral events (4/37 vs 0/20, χ2=0.964, P=0.326) between drugs discontinuation group and drugs continuation group within 2 weeks after surgery. The results of multivariate logistic regression analysis showed that drugs discontinuation before surgery was not an independent influencing factor for bleeding events ( OR=0.656, 95% CI 0.195-2.206, P=0.496), however combination of aspirin and clopidogrel before surgery was an independent influencing factor for bleeding events ( OR=4.038, 95% CI 1.044-15.626, P=0.043). All cardio-cerebral events (4 cases) happened in drugs discontinuation group, and myocardial angina in 6 months before surgery ( OR=9.764, 95% CI 0.928-102.682, P=0.058) and increased serum calcium concentration ( OR=1.491, 95% CI 0.976-2.278, P=0.065) were related with an elevated trend for cardio-cerebral events. Conclusions:Whether anticoagulant or antiplatelet drugs are discontinued before catherization surgery for peritoneal dialysis is not an independent influencing factor for bleeding events after surgery. The risk of postoperative bleeding in patients using combination of aspirin and clopidogrel should be paid attention. Myocardial angina in 6 months before surgery and higher serum calcium are related with an elevated trend for cardio-cerebral events after drugs discontinuation.

In this paper, experiments were designed for inducing neutral, terrified, excited, annoying emotions, and also low, middle, high, three levels of tension emotions of stress state, respectively. Based on the multi physiological signals generated by the subjects in emotions, such as heart rate and respiration rate and so on, we extracted features from these data which had been eliminated the baseline. Then the Particle Swarm Optimization method was adopted to optimize the features selection from the features of multi physiological signals, and combined with k-Nearest Neighbor algorithm, different emotions and varying degree tensions were classified. The result shows that the classification accuracy of the kNN method with SPO and baseline eliminated is better than the traditional kNN method.

Objective:To analyze the feasibility and advantages of gastric triangle suspension technique in laparoscopic radical anterograde modular pancreatiplenectomy (L-RAMPS) for patients of pancreatic body and tail malignant tumor.Methods:The clinical data of 29 patients with L-RAMPS in Li Huili Hospital of Ningbo Medical Center from January 2019 to October 2023 were retrospectively analyzed, including 14 males and 15 females, aged (67.6±7.5) years. According to whether gastric triangle suspension was used during operation, 29 patients were divided into suspension group ( n=14) and control group ( n=15). The two groups were compared with several indexes of body mass index, tumor length, postoperative pathological type, operation time, intraoperative blood loss, intraoperative incision margin, intraoperative blood transfusion, pancreatic fistula, postoperative massive bleeding, postoperative gastroparesis, length of hospital stay and so on. Results:There were no significant differences in age, sex, body mass index, tumor length and pathological type between the two groups (all P>0.05). Postoperative pathologic findings of the 29 patients included 21 cases of pancreatic adenocarcinoma (72.4%), 2 cases of intraductal papillary mucinous tumors (6.9%), 2 cases of pancreatic neuroendocrine tumors (6.9%), 1 case of pancreatic adenosquamous carcinoma (3.4%), and 3 cases of mucinous cystadenocarcinoma (10.3%). There was no significant difference in the proportion of positive first incision margin, intraoperative blood transfusion, postoperative B/C pancreatic fistula, postoperative massive hemorrhage and postoperative gastroparesis between the two groups (all P>0.05). The operative time and intraoperative blood loss in the suspension group were (200.3±13.5) min and (148.6±42.2) ml respectively, less than that in the control group (223.5±36.3) min and (205.3±63.3) ml, and the hospital stay in the suspension group was 14 (12, 17) d, shorter than that in the control group 26 (17, 32) d. The differences were statistically significant (all P<0.05). Conclusion:Gastric triangle suspension in L-RAMPS for patients of pancreatic body and tail malignant tumor can reduce the amount of intraoperative bleeding, shorten the operation time and hospital stay, is a reliable and simple suspension method.

Objective:To explore the effect of the situational doctor-patient communication skills training course based on chest pain center.Methods:The "5+3" integrated students of clinical medicine were selected to take the doctor-patient communication skills training course. The typical cases of chest pain center were written as module units, and were divided into 3 modules according to the disease types and the training contents of doctor-patient communication. The effect evaluation was performed before the course and after each module course, including the Liverpool doctor communication skills assessment scale, the college student empathy ability scale and emotional intelligence evaluation scale.Results:The students' communication ability, empathy ability, and emotional intelligence were significantly improved by three modules of practical training courses (all P<0.05). Among them, the communication ability of medical students was improved after each lecture in module 1, module 2 and module 3 (all P<0.05), which was 84% higher than that before the course [(28.2±2.7) vs. (15.3±3.9)]. After each lecture in module 1 and module 2, the empathy ability of medical students was improved (both P<0.05), which was 34% higher than that before teaching [(132.7±12.5) vs. (99.0±17.4)]. After each lecture in module 2 and module 3, the emotional intelligence of medical students was improved by 34% [(138.5±13.0) vs. (103.0±16.6)] (both P<0.05). Conclusion:The situational doctor-patient communication skills training course based on chest pain center, as a practical course of doctor-patient communication for medical students at the undergraduate stage, can effectively improve students' doctor-patient communication ability, empathy ability and emotional intelligence.

Chinese Journal of Gastroenterology 2021;26(5):312-316
Helicobacter pylori (Hp) resides in the epithelium of gastric mucosa and can cause chronic inflammation. Under the conventional white light endoscopy, normal gastric mucosa, current Hp-infected gastric mucosa and past Hp-infected gastric mucosa have different endoscopic features. High-resolution white light endoscopy and various new image-enhanced endoscopy are helpful to accurately diagnose the infection of Hp, and thereby improving the detection rate of early gastric cancer by identifying the high-risk endoscopic manifestations related to gastric cancer. This article reviewed the endoscopic diagnosis of Hp infection and its clinical value.

Objective:To verify the accuracy of the Kyoto classification score of gastritis for the endoscopic prediction of the Helicobacter pylori( H. pylori)infection in Chinese population. Methods:From June 2020 to January 2021, at the Digestive Endoscopy Center of the First Affiliated Hospital of Zhejiang Chinese Medical University, the clinical data of 489 patients who underwent gastroscopy examination were collected and the gastric mucosal manifestations under white light endoscopy (including atrophy, intestinal metaplasia, widening of gastric fold, nodularity, diffuse redness, white sticky mucus, etc.) were recorded according to the Kyoto classification of gastritis. H. pylori infection of the patients was determined according to 13C-urea breath test, histopathological examination and anti- H. pylori antibody test. The Kyoto classification score of gastritis of each patient was calculated. The sensitivity, specificity and odds ratio( OR)(95% confidence interval(95% CI)) of various endoscopic appearances in prediction of H. pylori infection were analyzed. Chi-square test was used for statistical analysis. Results:Among the 489 patients, 246 patients had H. pylori infection and 243 patients did not have H. pylori infection. There were 242 patients with Kyoto gastritis score ≥ 2, among them 215 cases had H. pylori infection and 27 cases did not have H. pylori infection. The accuracy of Kyoto classification score of gastritis in predition of H. pylori infection was 88.14% (431/489). Among the five indexes of the Kyoto classification score of gastritis, there was no significant difference in the incidence of intestinal metaplasia between patients with H. pylori infection and patients without H. pylori infection ( P>0.05). The incidence rates of atrophy, widening of gastric fold, nodularity and diffuse redness were higher in patients with H. pylori infection than those in patients without H. pylori infection (68.3%, 140/205 vs. 31.7%, 65/205; 95.2%, 99/104 vs.4.8%, 5/104; 89.7%, 35/39, vs.10.3%, 4/39; 85.0%, 227/267 vs.15.0%, 40/267), and the differences were statistically significant ( χ2=45.68, 106.46, 26.37 and 283.48, all P<0.01). The sensitivity, specificity and OR (95% CI) of atrophy, widening of gastric fold, nodularity and diffuse redness in prediction of H. pylori infection were 56.91%, 73.25%, and 3.62 (2.47 to 5.29); 40.24%, 97.94% and 32.06 (12.76 to 80.57); 14.23%, 98.35%, 9.91 (3.47 to 28.35); and 92.28%, 83.54% and 60.63 (34.02 to 108.08), respectively. The sensitivity and specificity of atrophy in prediction of H. pylori infection were low, and the diagnostic efficacy was general. The incidence rates of white sticky mucus and spotty redness of the gastric fundus and body were higher in patients with H. pylori infection than those in patients without H. pylori infection (86.5%, 32/37 vs. 13.5%, 5/37; 86.9%, 146/168, vs. 13.1%, 22/168), and the differences were statistically significant ( χ2=20.96 and 137.12, both P<0.01). The sensitivity, specificity, and OR (95% CI) of the two indicators in prediction of H. pylori infection were 13.01%, 97.94% and 7.12 (2.72 to 18.60), and 59.35%, 90.95%and 14.67(8.84 to 24.34), respectively, and the diagnostic efficacy was ideal. Conclusions:The Kyoto classification score of gastritis used for the endoscopic prediction of H. pylori infection is suitable for Chinese population. However, from the perspective of individual indicator, the diagnostic efficiency of atrophy and intestinal metaplasia is unsatisfactory. At the same time, attention should be paid to whether there is sticky mucus or spotty redness of the gastric fundus and body.
