Objective:To introduce the clinical application of "page-turning" superior pancreatic lymph node dissection in laparoscopic D2 radical gastrectomy for gastric cancer.Methods:Patients who were confirmed to have adenocarcinoma by preoperative gastroscopy and pathological biopsy, with tumor staging evaluated by imaging as cT1~4aN0~3M0, without neoadjuvant therapy, and without absolute surgical contraindications, underwent laparoscopic radical gastrectomy for gastric cancer with "page-turning" superior pancreatic lymph node dissection. The "page-turning" superior pancreatic lymph node dissection was performed in four steps: (1) Expose the posterior gastric mesentery and dissect No.11p lymph nodes; (2) Expose the left gastric mesentery and dissect No.7, No.8a and No.9 lymph nodes; (3) Expose the right gastric mesentery and dissect No.5 lymph nodes; (4) Expose the left edge of the portal vein and dissect No.12a lymph nodes.Results:From April 2018 to October 2024, 112 patients with gastric cancer underwent laparoscopic D2 radical gastrectomy with "page-turning" superior pancreatic lymph node dissection, including 21 cases in the First Affiliated Hospital of Guangzhou University of Chinese Medicine, 78 cases in the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, and 13 cases in the Department of Gastrointestinal Surgery, Jilin Provincial People's Hospital. The TNM staging of all patients was as follows: 31 cases in stage Ⅰ, 24 cases in stage Ⅱ, and 57 cases in stage Ⅲ; 62 cases of differentiated adenocarcinoma and 50 cases of undifferentiated adenocarcinoma; the median length of tumors was 3.8 cm. All patients successfully completed the operation without conversion to open surgery, no intraoperative massive hemorrhage or postoperative death. The median total number of lymph nodes dissected in all patients was 32, and the median number of positive lymph nodes was 4.5. The overall postoperative complication rate was 5.4% (6/112), all of which were Clavien-Dindo grade Ⅱ, including pulmonary infection, pleural effusion, and incisional infection, all cured by symptomatic treatment. The median follow-up was 41.8 (2-78) months, with 7 cases lost to follow-up. During the follow-up period, 27 cases (25.7%) had tumor recurrence and 16 cases (15.2%) died.Conclusions:The "page-turning" superior pancreatic lymph node dissection technique is safe and feasible in laparoscopic radical gastrectomy for gastric cancer.

Objective To investigate the correlation between peripheral blood total bilirubin(TBIL)levels and the efficacy and prognosis of immunotherapy in advanced non-small cell lung cancer(NSCLC),as well as its relationship with immune inflammation.Methods A retrospective analysis was conducted on 246 patients with advanced NSCLC who received immunotherapy from June 2019 to June 2022.Pre-treatment TBIL levels were collected,and the optimal cutoff value for TBIL was determined using the"X-tile"software and the ROC curve.The impact of pre-treatment TBIL on the short-term efficacy and long-term prognosis of advanced NSCLC was an-alyzed.Results The optimal cutoff value for TBIL was identified as 10.5μmol/L using the"X-tile"software and the ROC curve.A-nalysis of short-term efficacy indicated that patients with higher TBIL levels had a significantly better objective response rate(ORR)compared to those with lower levels(51.3％vs 33.8％,P=0.006).The disease control rate(DCR)was also higher in the higher TBIL level group compared to the low level group(92.9％vs 81.2％,P=0.007).Kaplan-Meier survival analysis revealed that patients with elevated TBIL levels had a longer median progression-free survival(PFS)compared to those with lower TBIL levels,with 13.0 vs 7.0 months,respectively(P＜0.001).Similarly,the median overall survival(OS)was greater in the higher TBIL level group than in the lower TBIL level group,with 16.0 vs 12.0months,respectively(P＜0.001).Additionally,there were significant differences in neutro-phil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),and systemic immune-inflammation index(SII)between two groups of different TBIL levels(P＜0.05).Conclusion In immunotherapy for advanced non-small cell lung cancer,patients with higher baseline levels of TBIL exhibit a positive correlation with the efficacy and prognosis of immunotherapy.TBIL might be served as an important predictive marker for immunotherapy in patients with advanced NSCLC.

Objective To discusse the application effects of the informatization of the review center and the homogeneity of pharmacists on the rationality of emergency department prescriptions.Methods Based on the system rules of the rational drug use management system and manually set custom rules,the changes in pharmacist's review quality,efficiency homogeneity,and prescription rationality were compared before(February 2023 to July 2023)and after(August 2023 to January 2024)the construction of the review center,according to the informatization and process standardization management.Results After the establishment of the review center,analysis of variance showed that the approval rate of pharmacist's review significantly increased compared to before the establishment of the review center(P＜0.05),while the average time consumption increased significantly(P＜0.01).The average review time,average approval time,and average review return time have been extended from(4.50±0.58),(4.50±0.58),and(4.75±0.96)s to(11.67±1.03),(8.50±0.55)and(13.17±0.98)s,respectively.The trend chi-square test showed that the irrationality rate of emergency department prescriptions decreased monthly from 6.27％in August 2023 to 0.93％in January 2024(P＜0.01).Correlation analysis between the number of intervention system rules since the establishment of the review center and the irrationality rate of emergency department prescriptions revealed a significant correlation(P=0.004 4).Conclusions By utilizing the platform of the review center,establishing dedicated review pharmacists and an information pharmacist team,and implementing informatization and standardized management processes,it can contribute to improving the quality and efficiency of prescription review,increasing the qualification rate of prescriptions,ensuring rational drug use,and enhancing the management level and medical quality of hospitals.

Objective To analyze the correlation of neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),and systemic immune-inflammatory index(SII)with short-term outcome and long-term prognosis in patients with advanced non-small cell lung cancer(NSCLC).Methods A retrospective study was conducted.A total of 215NSCLC patients who received a complete 4-cycle chemotherapy combined with immunotherapy or chemotherapy alone in the Department of Respiratory and Critical Care Medicine,Affiliated Hospital of Xuzhou Medical University from January 2021 to January 2023 were selected as the research subjects.The patients were divided into remission group(n=97)and non-remission group(n=118)based on the efficacy of the treatments,and the differences in NLR,PLR,SII,and decline rate of each index were compared between the two groups.NLR,PLR,SII and decline rate before and after treatment were grouped by the best cut-off value or median,and the differences in progression-free survival and overall survival were analyzed by each index group.Results NLR and PLR in the remission group before each cycle of treatment were signifi-cantly lower than those in the non-remission group,and SII in the remission group before cycles 2nd,3rd,and 4th of treatment were sig-nificantly lower than those in the non-remission group(P＜0.05);From initial treatment to before the fourth treatment cycle,NLR and SII decline rates in the remission group were significantly higher than those in the non-remission group(P＜0.05);the tumor stage,NLR before cycle 4th of treatment were independent influencing factors of short-term efficacy in patients with advanced NSCLC(P＜0.05);patients with low NLR,PLR,SII and higher rates of decline in NLR and SII before cycle 4th treatment had longer progression-free survival and overall survival(P＜0.05).Conclusion Tumor stage and post-treatment NLR are significantly correlated with the short-term outcomes of patients with advanced NSCLC,and high post-treatment NLR often suggests a poorer response to treatment.The prognosis of advanced NSCLC patients with higher NLR decline rate and higher SII decline rate after treatment is better.

Objective:To explore the effect of Pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) with chemotherapy on breast cancer patients who got agranulocytosis of 3 to 4 degree, agranulocytosis with fever (FN) and the influential factors of relative dose intensity (RDI) chemotherapy scheme. Meantime, the value of CD34 + and CD45 in peripheral blood on predicting agranulocytosis of 3-4 degree were investigated.Methods:A total of 104 women with breast cancer were treated at Huzhou Maternal and Child Health Hospital and Cancer Hospital of Zhejiang Province from Jan. 2022 to Sep. 2023. All subjects received primary prevention with PEG-rhG-CSF during chemotherapy. The clinical risk factors of agranulocytosis, FN and RDI were analyzed. The levels of CD34 + and CD45 in peripheral blood samples were analyzed by flow cytometry. Then the predictive value of the receiver characteristic curve (ROC) for Grade 3 to 4 agranulocytosis after primary prophylaxis with PEG-rhG-CSF for breast cancer chemotherapy was evaluated.Results:Among 104 breast cancer patients who received primary prevention of PEG-rhG-CSF during chemotherapy, 28 patients had agranulocytosis of 3 to 4 grade, 10 patients got FN, and 12 patients developed RDI<85%. The results of single factor analysis showed that CD34 +, CD45 and chemotherapy scheme were the influential factors of agranulocytosis of 3 to 4 degree, and low RDI of chemotherapy scheme ( OR=0.584, OR=0.999, OR=2.299, OR=0.100, OR=0.999, OR=3.088, P<0.05) . It also showed that CD34 + and chemotherapy scheme were the influential factors of FN ( OR=0.099, OR=2.667, P<0.05) . Multivariate Logistic regression analysis showed that CD34 +, CD45 and intensive chemotherapy were the independent risk factors of agranulocytosis of 3 to 4 degree after primary prevention with PEG-rhG-CSF ( OR=0.602, OR=0.999, OR=20.174, P<0.05) . CD34 + and intensive chemotherapy scheme were the independent influential factors of FN and RDI of chemotherapy scheme after primary prevention with PEG-RHG-CSF ( OR=0.072, OR=33.934, OR=0.086, OR=54.788, P<0.05) . The area under the curve (AUC) of CD34 + were 0.767 (95% CI:0.659-0.876) , AUC of CD45 were 0.743 (95% CI:0.644-0.842) , and the AUC of combined two indexes was 0.825 (95% CI:0.730-0.920) , which was higher than that of single index. So AUC of CD34 + and CD45 can be used for predicting agranulocytosis of grade 3 to 4 in breast cancer patients receiving primary prophylaxis with PEG-rhG-CSF. Conclusions:The levels of CD34 + and CD45 in peripheral blood of breast cancer patients with agranulocytosis of grade 3 to 4 receiving primary prevention with PEG-rhG-CSF during chemotherapy are lower. Combined detection of CD34 + and CD45 in peripheral blood can predict the occurrence of agranulocytosis of grade 3 to 4 in breast cancer patients after primary prevention with PEG-rhG-CSF. Also it can provide a reliable basis for assessing the risk of grade 3 to 4 agranulocytosis.

Objective:To discuss the feasibility and safety of stage I anastomosis and T-tube fistulation in laparoscopic local resection of duodenal tumors.Methods:A descriptive case series study was used to retrospectively analyze the clinical diagnosis and treatment data of 14 patients with duodenal tumors who successfully underwent laparoscopic local resection of duodenal tumors + phase I anastomosis + T-tube ostomy in the Guangdong Provincial Hospital of Chinese Medicine and the First Affiliated Hospital of Guangzhou University of Chinese Medicine from October 2021 to March 2024. The resection and reconstruction steps of laparoscopic local resection of duodenal tumor + phase I anastomosis + T-tube ostomy are as follows: (1) after the safe margin is clear, the duodenal tumor is completely removed in full thickness, and the specimen bag is taken out and sent to frozen section to determine the nature of the tumor and the negative margin; (2) Perforate the anterior duodenal wall below the tumor plane, place a 16# T tube, and fix it with laparoscopic purse string suture. The abdominal wall is led out through the duodenum, and the duodenal T tube fistulation is performed; (3) The duodenum was continuously sutured in a full-thickness transverse shape, and the seromuscular layer was strengthened to form a phase I anastomosis. The nutritional improvement of patients after operation was mainly observed, and the intraoperative situation and postoperative complications were recorded.Results:No conversion to laparotomy, postoperative emergency reoperation, intraoperative and postoperative complications occurred in 14 patients with duodenal tumors who completed laparoscopic local resection of duodenal tumors + phase I anastomosis + T-tube ostomy. The operation time was (225.43 ± 56.54) min, and the intraoperative blood loss was (72.14 ± 74.65) ml. The patient recovered well after operation, and no severe postoperative abdominal bleeding occurred. Postoperative gastrointestinal angiography showed that the anastomotic stoma was unobstructed, and there were no stenosis, anastomotic leakage and other related complications. There was no significant difference in serum albumin [(37.09 ± 3.53) g/L vs. (37.52 ± 4) g/L] and hemoglobin [(100.79 ± 31.93) g/L vs. (103.07 ± 19.6) g/L] between before and 1 week after operation ( P > 0.05). Conclusion:Laparoscopic local resection of duodenal tumor + phase I anastomosis + T-tube fistulation can be used as one of the safe and feasible improved methods for local resection of duodenal tumor to effectively reduce the occurrence of related complications.

This study was aimed at preliminarily assessing the prevalence of latent tuberculosis infection(LTBI)among cattle farming and slaughterhouse workers across Wuxue,Xianning,and Yichang Cities in Hubei Province,and exploring associated risk factors.Data on cattle farming and slaughterhouse workers were gathered via a questionnaire.LTBI detection was performed with a tu-berculin skin test and interferon-gamma release assay,and influencing factors were subsequently analyzed.The LTBI prevalence among cattle farming and slaughterhouse personnel in the three cities was 30.50%,and a higher rate was observed in slaughterhouse workers(39.01%)than cattle farmers(21.63%)(P<0.01).Multifactor analysis indicated that working in slaughterhouses(95%CI:1.582-3.878),having a history of tuberculosis(95%CI:1.377-25.057)or BCG vaccination(95%CI:1.229-3.285),and having a college education or above(95%CI:0.303-0.859)were significant factors influencing LTBI positivity in these personnel.Having more than 30 years of work experience(95%CI:1.303-18.782)was a risk factor for personnel at cattle breeding farms.Among slaugh-terhouse personnel,having a college education or above(95%CI:0.164-0.894),11-20 years of work experience(95%CI:0.122-0.994),or a history of tuberculosis(95%CI:1.661-64.397);performing logistics work(95%CI:3.234-126.424);and working in slaughter-related positions(95%CI:1.209-19.639)were associated with LTBI positivity.Therefore,the slaughterhouse workers in the three cities had higher LTBI rates than the cattle farming workers,thus underscoring the need for increased attention to personnel in logistics and slaughter-related positions.
