Objective To explore the value of dual-channel anastomosis of residual stomach and jejunum in radical resection of the upper gastric cancer. Methods Forty patients with upper gastric cancer had undergone proximal gastrectomy and dualchannel digestive tract reconstruction, including esophagus-jejunum side to side anastomosis, residual stomachjejunum anastomosis, and jejunum-jejunum anastomosis. Results The cutting margin away from tumor in all the cases was more than 5 cm and no carcinoma residual. The number of lymph nodes dissection was 21±6, reaching the requirement of D2 radical surgery. There was no case appearing complications such as anastomotic leakage, obstruction or bleeding. Barium meal examination after operation showed that most of barium was directly into the jejunum, the remaining went through the duodenum into the jejunum without gastroesophageal reflux. Followed up 6-30 months with average 18 months, there were no visible reflux esophagitis in all the cases, and only 1 case appeared minor dumping syndrome. The hemoglobin increased and the quality of life was satisfactory after operation. Conclusions In regard to dual-channel anastomosis of residual stomach and jejunum, resection range is reasonable, dissection scope accords with the protocol and residual stomach has a certain pouch effect. The anastomosis has a favorable prevention from reflux esophagitis and dumping syndrome and retains the duodenum pathway, so that improves the quality of patients’ life and is a relatively ideal digestive tract reconstruction.
ObjectiveTo explore the conversion treatment value of Faricimab in patients with neovascular age-related macular degeneration (nAMD) who had sub-optimal response to anti-vascular endothelial growth factor (VEGF) drug therapy, and to preliminarily evaluate its clinical effect. MethodsA retrospective clinical study. From March 2024 to January 2025, 25 patients (32 eyes) diagnosed with nAMD at Department of Ophthalmology of General Hospital of Central Theater Command were included in the study. All affected eyes were converted to receive Faricimab treatment due to sub-optimal response to previous anti-VEGF drug therapy. The treatment plan is to provide treatment as needed after the first injection based on the follow-up results. The best corrected visual acuity (BCVA) and swept-source optical coherence tomography angiography (SS-OCTA) were evaluated. BCVA examination was conducted using the Snellen visual acuity chart and converted to the logarithm of the minimum angle of resolutionn (logMAR) visual acuity for statistical analysis. The SS-OCTA system automatically calculates indicators such as central retinal thickness (CRT), choroidal neovascularization surface area (CSA), and choroidal neovascularization flow area (CFA). The main observations were made on the changes of BCVA, CSA, CFA, CRT and adverse reactions at 1, 3 and 6 months after treatment. A mixed linear model was adopted to compare the differences between each index and the baseline. ResultsAmong the 25 patients, 20 were male (80.0%, 20/25) and 5 were female (20.0%, 5/25). Age was (66.6±11.2) years old. The disease course was (41.2±36.4) months. Previously received anti-VEGF drug treatment (20.5±21.6) times, involving 2.2 types of drugs. Among the 32 eyes, 16 (50.0%), 11 (34.4%), and 7 (21.9%) eyes had subretinal fluid, intraretinal fluid, and both coexisting, respectively. At baseline, the logMAR BCVA of the affected eye was 0.67±0.41, the CSA and CFA were (7.46±6.27) and (3.26±2.59) mm2, respectively, and the CRT was (380.75±147.56) μm. At 1, 3, and 6 months after switching to Faricimab treatment, logMAR BCVA improved to 0.57±0.42, 0.55±0.41, and 0.50±0.35, respectively. The corresponding CSA were (6.36±6.10), (6.44±6.12), and (6.44±5.96) mm2. The corresponding CFA values were (2.79±2.50), (2.35±2.25), and (2.59±2.35) mm2. The corresponding CRT were (330.64±147.56), (329.44±130.73), (340.05±144.56) μm. Compared with the baseline, BCVA significantly improved at each time point after treatment, and CSA and CFA significantly decreased. The differences were statistically significant (P＜0.05). At 1 and 3 months after treatment, CRT was significantly lower than the baseline, and the difference was statistically significant (P=0.005, 0.025). During the follow-up period, the intraocular pressure of all affected eyes remained normal, and no serious adverse events such as intraocular infection occurred. ConclusionFor nAMD patients with poor response to anti-VEGF drug treatment, switching to Faricimab treatment can effectively improve the BCVA and anatomical structure (including CSA, CFA and CRT) of the affected eyes, and has good safety.
Objective
To explore the application effect of " dual-channel teaching” of the rain classroom platform in airway obstruction teaching.
Methods
A total of 228 nursing undergraduate students in Grade 2015 were selected as the research subjects by the method of cluster random sampling. Class B (n=115) was randomly selected as the control group and Class A (n=113) was selected as the experimental group. Class B adopted the traditional practical teaching mode, and Class A was integrated with the rain classroom platform on this basis. After the end of the course, the learning situation of the experimental group students were understood through the rain classroom background data, the teaching effects of the two groups were evaluated by the students’ theoretical scores and applied case test scores, and the experimental group student’s evaluation of the rain class was understood by questionnaire survey.
Results
There were 105 nursing students (92.92%) completing pre-school preparation tasks, 103 (91.15%) participating in the class answering, and 113 (100.00%) completing the after-school exercises. The theoretical scores and applied case assessment scores of the experimental group students were 79.44±6.25 and 83.24±3.64, respectively, and those of the control group students were 68.50±7.96 and 70.59±5.51, respectively, the differences between the two groups were statistically significant (P<0.05). In the experimental group, 92 nursing students (81.42%) liked the rain classroom platform teaching.
Conclusion
The rain classroom platform teaching can bring about the ecological transformation of the open speech in classroom, and comprehensively improve the overall quality and comprehensive ability of students, which is worthy of promotion and application in teaching.
