Objective:To investigate the application value of mixed reality technology in surgical conversation of laparoscopy radical resection of gastric cancer.Methods:The prospective randomized controlled study was conducted. There were 80 family members of patients with gastric cancer who were admitted to Nanfang Hospital of Southern Medical University from June 2021 to December 2022 being selected as subjects. All patients underwent laparoscopic radical resection of gastric cancer. Based on random number table, all subjects were allocated into the control group and the experiment group. Subjects in the control group performed routine surgical conversation and subjects in the experiment group performed surgical conversation based on mixed reality technology. Observation indicators: (1) baseline data of the subjects; (2) anxiety assessment of the subjects. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for inter-group comparison. Repeated measurement data were analyzed using the repeated ANOVA. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. Results:(1) Baseline data of the subjects. A total of 80 subjects were selected for eligibility, including 40 subjects in the control group and 40 subjects in the experi-ment group. There were 44 males and 36 females, aged (40±9)years. The gender (male, female), age, education background (primary school education, middle school education, high school education, junior college education, undergraduate education, postgraduate education) were 23, 17, (39±9)years, 1, 3, 9, 16, 9, 2 in subjects of the control group, versus 25, 15, (42±10)years, 0, 8, 6, 11, 14, 1 in subjects of the experiment group, showing no significant difference in the above indicators between the two groups ( χ2=0.20, t=?1.64, Z=?0.10, P>0.05). (2) Anxiety assessment of the subjects. The scores of self-rating Anxiety Scale (SAS) and Hospital Anxiety Scale (HADS) before surgical conversation, after surgical conversation, after surgery were 41±10 and 26±5, 49±11 and 32±3, 40±13 and 15±8 in subjects of the control group, versus 44±9 and 23±3, 66±16 and 28±6, 34±14 and 8±3 in subjects of the experiment group, showing significant differences in the above indicators between the two groups ( FSAS组间=8.83, FSAS时间=40.41, FSAS交互=12.21, FHADS组间=32.42, FHADS时间=321.28, FHADS交互=6.15, P<0.05). Conclusion:Compared with traditional surgical conversation, mixed reality technology based surgical conversation can relieve the postoperative conxiety of subjects.

Effect of flipped class model based on SPOC in the course ofMedical Nursingteaching / 中国实用护理杂志

Objective To explore the application of flipped class model based on SPOC in the course of internal medical nursing. Methods Randomly selected from Shanxi University of Medical grade 2014, 206 undergraduate students as the research object. The control group (104) and experimental group (102) .The experimental group used flipped class model based on Small Private Online Course (SPOC) teaching method;the control group used the traditional teaching mode. After the end of the course, compared two groups nursing students′self-regulated learning ability and critical thinking ability whether there are differences by autonomous learning ability scale and Chinese version of critical thinking disposition inventory (CTDI-CV). Results The experimental group students′theory assessment results, critical thinking ability and self-regulated learning ability were (75.68 ± 9.32), (303.04 ± 16.54), (112.39 ± 11.10) higher than the control group (69.43 ± 11.41), (288.23 ± 15.84), (102.58 ± 9.31), the difference was statistically significant (t = 2.837,3.451,3.512, P<0.05). Conclusions The flipped class model based on SPOC teaching method was better than traditional teaching mode, it improved the students' theory assessment results and self-regulated learning ability and critical thinking ability.

A research progress on risk factors for stroke related infections / 中国实用护理杂志

Value of serum amyloid A in patients with acute asthma attack / 实用医学杂志

Objective To assess the value of serum amyloid A (SAA) in patients with acute asthma attack. Methods Sixty-four asthmatic patients in acute phase and 20 healthy individuals were included. The asthmatic patients were divided into bacterial infection-induced group and non-bacterial infection-induced group. Lung function test and chest X-rays test were conducted And inflammatory cell counts , serum SAA and CRP levels were measured. SAA were compared among subgroups of asthmatic patients and healthy controls and the diagnostic value of SAA to distinguish bacterial infection-induced asthma was estimated. Results SAA of both asthma subgroups were significantly higher when compared with the healthy individuals, and it was higher in bacterial infection-induced group than that in non-bacterial infection-induced group. In terms of ROC curve , AUC was 0.966 for SAA to distinguish merging bacterium infection, and the cut-off value was 36.67mg/L with sensitivity of 92.3% and specificity of 88.2%. Conclusions SAA increases in patients during acute asthma attack, and particularlymore obviously in bacterial infection-induced patients. It may be used as a reliable biomarker to distinguish merging bacterium infection during acute asthma attack.

Minimally invasive technique for the correction of pectus carinatum / 中华胸心血管外科杂志

Objective Minimally invasive technique was used in the treatment of pectus carinatum. Indication, techni-cal details and perioperative complication are discussed in this paper. Methods From March 2008 to January 2009, 6 patients with pectus carinatum underwent minimal invasive operation by using the principle of Nuss procedure in which pressure applied through a curved steel bar that was placed subcutaneously anterior to the sternum, via lateral thoracic incisions. Preoperative CT scan were performed and Hailer index was used as operative indication. Results The average age of patients was (13.6 ± 1.94) years (range, 10 - 16 years). They were all males. The mean operation time was (104.17 ± 15.63) minutes. The av-erage blood loss was (5.17±2.56) ml. The mean hospital stay was (5.67±0.82) days. Postoperative follow-up was 1 -11 months. Displacement of the stablizer was the only complication that was corrected by further fixation procedure. COnClusion The minimally invasive technique for the treatment of peetus earinatum is safe and effective with minimal complications. It can be selected as an alternative techniques and the appropriate age for this procedure is 10-16 years.

Diagnosis and treatment of congenital esophageal stenosis / 中华胸心血管外科杂志

Objective Base on the local pathology, the early diagnosis and a reasonable treatment for congenital esophageal stenosis (CES) were discussed. Methods Forty two cases of congenital esophageal stenosis during 1980～2000 were reviewed retrospectively, including age, vomitus and frequency, nutrition and development, diagnostic method used and operative pathological findings, time of normal feeding and time of nutritional restoration. Results According to local pathology, there were 26 cases of tracheobronchial remnant, 11 fibromuscular stenosis, 3 membranous diaphragm, and 2 ectopic gastric mucosa. Membranous diaphragm excision gave the best result without postoperative dilatation. The patients were followed up for 4～10 years, Normal feeding was restored in 1 month in 78 6%, 9 5% in 6 months, and 11 9% in 1 year. Conclusion Persistent vomiting of undigested food and failure in gaining weight are the chief complaints of congenital esophageal stenosis. The confirmatory diagnosis depends on barium swallowing and esophagoscopy. A good result can be achieved by follows local resection and necessary postoperative dilatation.
