Objective To analyze the correlation between the tubular gastric width and the anti gastroesophageal reflux after esophageal cancer operation,and to provide reference for the choice of surgical methods in treatment of esophageal cancer.Methods Selected 60 patients who received radical surgery for esophageal carcinoma combined with gastric tube reconstruction surgery in our hospital from January 2015 to October 2015,and divided them into two groups according to the way of stomach tube anastomosis (cervical anastomosis,thoracic anastomosis) and different width of gastric tube (greater than or equal to or less than 3 cm).Namely:cervical anastomosis + greater than or equal to 3 cm group(14 cases),cervical anastomosis + less than 3 cm group(15 cases),thoracic anastomosis + greater than or equal to 3 cm group(15 cases) and thoracic anastomosis + less than 3 cm group(16 cases).All patients recieved esophageal pH monitoring for 3 days continuously from the 11 th day after operation.The monitoring indicators include:number of reflux,accumulation time of pH < 4,whether there were clinical symptoms (heartburn,chest pain,pharyngeal foreign body sensation,cough,asthma,etc.) after surgery,and the frequency and time of these clinical symptoms appeared.All the patients were given endoscopic examination at the 14th days postoperatively.Observed the esophageal mucosa of patients and conducted histopathological grading of gastric mucosal inflammation.And then made a correlation analysis of gastric tube width and esophageal mucosal inflammation grade among all the patients with reflux symptoms.Results The cumulative time and number of reflux,incidence rate of clinical symptoms,and pH values less than 4 were significantly different(P < 0.05).The cumulative time and number of reflux,incidence rate of clinical symptoms,and pH values less than 4 in the cervical anastomosis + less than 3 cm group were significantly lower than that in the other 3 groups(P < 0.05),with statistical significance between different groups of endoscopic esophageal mucosa inflammation grade difference (P < 0.05).Esophageal mucosal inflammation grading in patients of the cervical anastomosis + less than 3 cm group was the lightest.It showed a linear correlation between the gastric tube width and esophageal mucosal inflammation grading in patients with reflux symptoms.Conclusion Postoperative gastroesophageal reflux is closely related to stomach esophagus width after resection of esophageal carcinoma with tubular stomach reconstruction of stomach esophagus,because it is unable to control gastric tube width to the appropriate range.And it should be strengthened in patients with reflux related indicators for monitoring,so as to take measures to prevent gastroesophageal reflux as soon as possible to improve the prognosis of patients with quality.

Objective:To analysis the policy tools and targets of the policies of free training for order-oriented medical students in rural areas of China, for reference for further improving the free medical student training policy.Methods:The research team searched the official websites of the State Council, National Health Commission, Ministry of Education, and other ministries, as well as the Peking University Treasure Database, for national level policy documents related to free training of order-oriented medical students released from June 2010 to May 2023. Policy tool-policy target analysis framework was used to quantitative analysis the policy documents.Results:A total of 16 policy documents were included and 213 policy provisions were extracted. From the perspective of policy tools, the proportion of policy provisions using imperative policy tools was the highest, accounting for 63.38% (135 articles), followed by advisory policy tools(18.78%, 40 articles)and reward based policy tools(13.61%, 29 articles), while functional expansion tools(2.82%, 6 articles) and authoritative restructuring tools(1.41%, 3 articles) accounted for a relatively low proportion. The institutional education stage is the main policy target, with provisions accounting for 76.06% (162 articles), followed by the continuing education stage and the post graduation education stage, accounting for 17.84% (38 articles) and 7.51% (16 articles), respectively. It was uneven distribution of various policy tools and their sub tools within the same policy target.Conclusions:The distribution of policy tools for the free training policy of rural order oriented medical students in China needed to be further balanced. The policy targets were mainly concentrated in the education stage of universities.

Objective:To investigate the effect of situational simulation drill in nurses training on prevention and treatment of venous thromboembolism (VTE).Methods:Totally 120 nurses in 1-3 years from a tertiary general hospital were selected to participate in the training for prevention and treatment of venous thromboembolism. They were divided into intervention group and control group according to the number of single and double packet ward. A total of 62 nurses in the single wards were selected as the intervention group, and a total of 58 nurses in the double wards were selected as the control group. The control group and the intervention group were trained on the prevention and treatment of venous thromboembolism by traditional teaching method and scenario simulation drill, and the effect was evaluated by Kirkpatrick Model.Results:After training, intervention group training object theory examination score, operation assessment score, clinical nursing work assessment score, and nurses ability to scale score (83.79±6.85), (87.00±4.57), (7.90±0.62), (79.03±8.24) respectively, were higher than the control group (80.67±7.90), (84.02±4.70), (7.21±0.72), (70.86±11.59), the score comparison difference was statistically significant ( t values were -3.660-5.670, P < 0.05); The satisfaction of the training object to the teaching plan, teaching content and teaching form in the intervention group was 88.71% (55/62), 87.10% (54/62) and 87.10% (54/62), which were all higher than the control group 74.14% (43/58), 72.41% (42/58) and 68.97% (40/58), with statistically significant differences ( χ2 values were 4.250, 4.038, 5.804, P<0.05). Conclusion:The application of situational simulation drill in the nursing training of prevention and treatment of VTE is helpful to improve the theoretical skills and clinical work ability of nurses in the prevention and treatment of VTE, and to increase the satisfaction of nurses with the training.

Objective:To evaluate the clinical outcomes of additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Sixty-nine patients with early gastric cancer who underwent ESD and were diagnosed as having non-curative resection by postoperative pathology at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2014 to December 2020 were included in the retrospective observation. Patients were divided into the additional surgery group ( n=12) and the follow-up group ( n=57). The differences in clinical and pathological data of the two groups, the surgical outcomes of the additional surgery group, three-year recurrence-free survival and tumor-specific survival of the two groups, and the independent risk factors affecting three-year recurrence-free survival in the follow-up group were analyzed. Results:Compared with the follow-up group, the rates of submucosal infiltration [66.7% (8/12) VS 21.1% (12/57), χ 2=7.927, P=0.005], vascular invasion [33.3% (4/12) VS 1.8% (1/57), P=0.003] and nerve invasion [16.7% (2/12) VS 0.0% (0/57), P=0.028] in the additional surgery group were significantly higher. In the additional surgery group, the interval between the additional surgery and ESD was 18.5 d (7-55 d), the surgical time was 286.4±85.9 min, and the number of dissected lymph nodes was 25.6±7.4. Four patients (33.3%) had residual tumor. Postoperative complications occurred in 4 patients (33.3%) (all were discharged after conservative treatment), and there was no perioperative death. One patient developed liver metastases 17 months after the surgery, and died 22 months after surgery due to liver metastases. One patient died 22 months after surgery due to non-tumor causes. The three-year recurrence-free survival and three-year tumor-specific survival in additional surgery group were 91.7% (11/12) and 91.7% (11/12), respectively, and those in the follow-up group were 87.7% (50/57) and 100.0% (57/57), respectively. Multivariate Cox regression analysis showed that tumor size ≥2 cm was an independent risk factor for three-year recurrence-free survival in the follow-up group ( P=0.037, HR=15.595, 95% CI: 1.181-205.952). Conclusion:Additional surgery and close follow-up are safe and feasible therapeutic strategies for early gastric cancer patients who underwent non-curative ESD. Clinicians should make reasonable choice based on the pathological results, patients' physical condition and surgery intention. But for patients with primary tumor size ≥2 cm, additional surgery is recommended.

Objective:To review the incidence and treatment status of perioperative anemia in patients with gastric cancer.Methods:The clinicopathological data of gastric cancer patients who underwent surgery at Department of Gastrointestinal Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from Jan to Dec 2019 were collected. Univariate analysis and multivariate Logistic regression analysis were used to explore the risk factors of preoperative anemia in gastric cancer.Results:A total of 879 patients were included in this study. The incidence of preoperative anemia in patients with gastric cancer was 35.6%. The incidence of postoperative anemia was 63.5%. The proportion of patients with preoperative anemia receiving treatment was 17.3%, and the proportion of patients with postoperative anemia receiving treatment was 17.4%. Univariate analysis showed that age, nutritional risk screening 2002, T stage, M stage, tumor stage and lymph node metastasis were associated with preoperative anemia (all P<0.05). Multivariate Logistic regression analysis showed that age >60 years , nutritional risk screening 2002 ≥3, T 3-4 stage and M 1 stage were independent risk factors for preoperative anemia in patients with gastric cancer (all P<0.05). Conclusions:The incidence of perioperative anemia in patients with gastric cancer is high. At present, the proportion of patients with perioperative anemia receiving treatment is low. High nutritional risk, advanced age, late tumor T stage and distant metastasis are independent risk factors for preoperative anemia in patients with gastric cancer.

OBJECTIVE:To study the protective effect of timosaponin BⅡ(TB-Ⅱ)on blood vessels and explore its possible mechanism. METHODS :Using aquaculture water as blank control ,the effects of 100,200 and 400 μg/mL TB-Ⅱ treatment for 48 h on the situation of subintestinal veins (SIVs)in normal zebrafish embryos 24 h after fertilization (24 hpf)were investigated. PTK787(0.06 μg/mL),a tyrosine kinase inhibitor ,was used to induce the model of zebrafish intestinal vascular injury ;using combing with 0.1% dimethyl sulfoxide but no PTK 787 as blank control ,combing with PTK 787 but no drug as model control ,the effects treatment of 100,200 and 400 μg/mL TB-Ⅱ for 48 h on the SIVs of zebrafish model with vascular injury were investigated. Relative expressions of fam-like tyrosine kinase 1(Flt-1),kinase insert domain containing receptor (Kdr),kinase insert domain containing receptor l (Kdr-l),vascular endothelial growth factor A (VEGF-A),tumor necrosis factor α(TNF-α)and interleukin 6 (IL-6)mRNA were detected by RT-PCR. RESULTS :100 μg/mL TB-Ⅱ could significantly increase the sprouting vessel of normal zebrafish SIVs sprouting vessel number (P<0.05),and 200 μg/mL TB-Ⅱ could significantly increase SIVs number of normal zebrafish (P<0.05). Compared with blank control , SIVs treatment (P<0.01),and the relative expressions of Flt-l , Kdr,Kdr-l,VEGF-A,TNF-α and IL-6 mRNA were alse decreased significantly (P<0.05 or P<0.01). After treated 化。E-mail:pn333@163.com with different concentrations of TB- Ⅱ ,SIVs number of vascular injury model zebrafish increase d to different extents ;relative expressions of Flt-l ,Kdr,Kdr-l,VEGF-A,TNF-α and IL-6 mRNA were increased to different extents. There was no significant difference in SIVs number and the expression of Flt-l ,TNF-α mRNA in zebrafish treated with 100 μg/mL TB-Ⅱ and the expression of TNF-α mRNA in zebrafish treated with 400 μg/mL TB-Ⅱ, but there was statistical significance in other indexes (P<0.05 or P<0.01). CONCLUSIONS :TB-Ⅱ has a certain function of promoting angiogenesis and repairing damaged blood vessels ,and its mechanism is related to the up-regulation of vascular endothelial growth factor receptor and pro-inflammatory cytokine expression.
