Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for circular superficial esophageal cancer.Methods:A retrospective analysis was conducted on 74 consecutive cases of circular superficial esophageal squamous cell carcinoma treated with ESD at Nanjing Drum Tower Hospital from January 2015 to December 2019. The success rate of ESD, curative resection rate, incidence of complications, and additional treatment were mainly observed.Results:One case was transferred to surgery, and the remaining 73 cases successfully completed ESD treatment. The success rate of ESD was 98.6%. Postoperative pathology of ESD revealed that 39 cases achieved curative resection, with a curative resection rate of 53.4% (39/73). Intraoperative muscle layer injury occurred in 15 cases (20.5%), and intraoperative perforation occurred in 1 case (1.4%). Two cases (2.7%) experienced delayed bleeding, and one case (1.4%) experienced delayed perforation. Eleven cases were lost to follow-up, and the remaining 62 cases received follow-up for 36.4±19.0 months. Among the follow-up cases, 12 underwent additional surgery and 5 cases additional chemotherapy and radiotherapy. Among the 57 patients with follow-up data who did not underwent surgery, 49 developed esophageal stenosis after ESD, with an incidence rate of 86.0%.Conclusion:ESD for circular superficial esophageal cancer is generally safe, but it is prone to muscle layer injury during the operation, with a low curative resection rate, a high incidence of postoperative esophageal stenosis, and a high proportion of additional surgical procedures.

Objective:To investigate the clinical efficacy of radical resection of pancreatic cancer after neoadjuvant conversion therapy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 23 patients who underwent radical resection of pancreatic cancer after neoadjuvant conversion therapy in Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2019 to May 2022 were collected. There were 17 males and 6 females, aged 58(range, 33-73)years. After neoadjuvant conversion therapy, the three-dimensional (3D) visualization was used to evaluate and classify tumor vascular invasion, and surgical plan was planned and implemented. Observation indicators: (1) situations of neoadjuvant conversion therapy; (2) surgical situations; (3) postoperative histopathological examination; (4) postoperative recovery; (5) follow-up. Measurement data with normal distribution were represen-ted as Mean± SD, and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3). Count data were described as absolute numbers. Results:(1) Situations of neoadjuvant conversion therapy. All 23 patients received the AG combination chemotherapy (albumin-paclitaxel+gemcitabine), including 14 patients combined with stereotactic body radiation therapy. Of the 23 patients, 22 cases achieved partial response, and 1 case showed stable disease. The CA19-9 of the 23 patients was 85.06(29.74,634.5)U/mL and 13.96(9.74,25.02)U/mL before and after neoadjuvant conversion therapy, respectively. (2) Surgical situations. According to the results of preoperative 3D visualization of tumor vascular invasion, 7 of the 23 patients were evaluated as arterial invasion, 8 cases were evaluated as venous invasion, 5 cases were evaluated as arterial and venous invasion, and there were 3 cases showing negative of vascular invasion. Of the 23 patients, 12 cases underwent pancreaticoduodenectomy, 4 cases underwent radical antegrade modular pancreatosplenectomy, 7 cases underwent total pancreaticoduodenectomy. For vascular reconstruction, there were 10 patients without vascular reconstruction, and there were 13 patients undergoing artificial vascular vein reconstruction. The operation time and volume of intraoperative blood loss of the 23 patients was (524±171)minutes and 1 000(400,1 600)mL, respectively. (3) Postoperative histopathological exami-nation. Results of postoperative histopathological examination in 23 patients showed that there were 2 cases with moderate-well differentiated tumor, 10 cases with moderate differentiated tumor, 7 cases with moderate-poorly differentiated tumor, 2 cases with poorly differentiated tumor, and 2 cases negative of tumor. The number of lymph node dissected in 23 patients was 16±7. There were 5 cases with lymph node metastasis and 18 cases without lymph node metastasis. There were 17 cases with nerve invasion and 6 cases without nerve invasion. All 23 patients were negative of vascular invasion. Of the 23 patients, there were 21 cases with R 0 resection and 2 cases with R 1 resection. For pathological TNM staging, there were 2 cases with 0 stage, 13 cases with Ⅰ stage, 7 cases with Ⅱ stage, and 1 case with Ⅳ stage. For postoperative pathological scoring, there were 2 cases achieved 0 point (complete pathological remission), 16 cases achieved 2 points (partial remission), and 5 cases achieved 3 points (no significant effect). (4) Postoperative recovery. The postoperative duration of hospital stay of 23 patients was 19(14,31)days. There were 17 of 23 patients underwent postoperative complications, including 11 cases with Clavien-Dindo Ⅱ stage complications, 3 cases with Clavien-Dindo Ⅲa stage complications, 1 case with Clavien-Dindo Ⅲb stage complication, 1 case with Clavien-Dindo Ⅳ stage complication, and 1 case with Clavien-Dindo Ⅴ stage complica-tion. (5) Follow-up. There were 22 patients underwent follow-up, with follow-up time as 12(9,23)months. There were 9 patients underwent postoperative recurrence and metastasis, with recurrence and metastasis time as 7.8(range, 6.0-12.0)months. During the follow-up, 15 of the 22 patients survived. Conclusion:Radical resection of pancreatic cancer after neoadjuvant conversion therapy is feasible.

Objective:To compare the histopathological features and treatment efficacy of different methods for metachronous early gastric cancer (MEGC) in the remnant stomach.Methods:A total of 66 patients [38 endoscopic submucosal dissection (ESD) and 28 gastrectomy] with MEGC in the remnant stomach from January 2014 to December 2020 in Drum Tower Hospital were divided into the ESD group and the gastrectomy group. The baseline characteristics, histopathological features, treatment efficacy, and cost differences of the two groups were analyzed.Results:The MEGC in the remnant stomach mostly occurred in elderly male patients, with the mean age of 69.7±8.5 years. The mean interval of the occurrence of MEGC in the remnant stomach was 6 years. As for the tumor location, the gastric body (31.6%) was the main location in the ESD group and gastric cardia (53.6%) in the gastrectomy group with significant difference ( χ2=11.07, P=0.026). The mean operation time, hospital stay, postoperative fasting time, and total treatment cost were 80.0 min, 6.0 d, 1.5 d, ￥19 436 in the ESD group and 215.0 min, 19.0 d, 6.5 d, and ￥68 665 in the gastrectomy group, respectively, with significant differences between the two groups ( P<0.05). The overall survival rate during follow-up was 76.3% in the ESD group and 71.4% in the gastrectomy group with no significant difference between the two groups ( χ2=0.736, P=0.778). In terms of postoperative complications, the incidences of bleeding and infection were 7.9% and 5.3% in the ESD group, and those of obstruction and infection were both 14.3% in the gastrectomy group. There was significant difference in the incidences of postoperative obstruction between the two groups ( P<0.05). Conclusion:ESD is safe and effective for MEGC in the remnant stomach and is better than gastrectomy in terms of the treatment cost and operation time, but the long-term efficacy still needs to be validated by large-scale prospective studies.

Objective:To analyze the clinicopathological features of histological mixed-type early gastric cancer and to compare the endoscopic pathological features of dominant proportions.Methods:Clinical data of 43 patients with histological mixed-type early gastric cancer who underwent endoscopic submucosal dissection (ESD) at the Department of Gastroenterology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2015 to December 2020 were retrospectively analyzed. The endoscopic characteristics, coincidence rate of preoperative diagnosis and postoperative pathology of the patients were analyzed. The endoscopic pathological findings of differentiation dominant group and undifferentiation dominant group were compared.Results:Histological mixed-type early gastric cancer was more common in patients over 60 years old (55.81%, 24/43) , male (65.12%, 28/43), and Helicobacter pylori ( HP) infection (69.77%, 30/43). Most lesions were found in atrophic background (79.07%, 34/43), and lower part of stomach (65.12%, 28/43). Redness or mixed redness was the main color (76.74%, 33/43), and 0-Ⅱc was the main type in lesion morphology (58.14%, 25/43). Characteristics of both differentiated and undifferentiated carcinoma could be observed under magnifying endoscopy. Only 16.28% (7/43) of the patients were diagnosed as having histological mixed-type carcinoma by biopsy. Postoperative pathology showed that there were 33 cases in differentiation dominant group and 10 cases in undifferentiation dominant group. There were 15 (34.88%) patients with deep submucosal infiltration, and 3 (6.98%) patients with positive lymphatic vessels. Differentiation dominant group had clearer demarcation line under endoscopy [78.79% (26/33) VS 4/10, χ2=7.753, P=0.012]. There was no significant difference between the two groups in gender, HP infection, background mucosa, lesion location, endoscopic morphology, lesion long diameter, color, or microscopic and microvascular manifestations under magnifying endoscopy ( P>0.05). Tub2+por was the most common pathological type in differentiation dominant group (78.79%, 26/33), and sig+tub2 was the dominant combination in undifferentiation dominant group (6/10). Endoscopic diagnosis of differentiated primary carcinoma was highly sensitive (93.94%, 31/33), and highly specific for undifferentiated primary carcinoma (94.28%, 33/35). Conclusion:Histological mixed-type early gastric cancer can be diagnosed qualitatively by endoscopy. It is difficult to accurately judge the differentiation advantage and the invasion depth before the operation, which is prone to postoperative pathological upgrading. Therefore, the indications should be strictly considered for ESD treatment for mixed-type early gastric cancer.
摘要
Objective: To investigate the impact of molecular classification and key oncogenes on the oncologic outcomes in patients with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) receiving fertility-preserving treatment. Methods: Patients with EC and AEH undergoing progestin-based fertility-preserving treatment and receiving molecular classification as well as key oncogenes test at Obstetrics and Gynecology Hospital, Fudan University from January 2021 to March 2023 were reviewed. Hysteroscopic lesion resection and endometrial biopsy were performed before initiating hormone therapy and every 3 months during the treatment to evaluate the efficacy. The risk factors which had impact on the treatment outcomes in EC and AEH patients were further analyzed. Results: Of the 171 patients analyzed, the median age was 32 years, including 86 patients with EC and 85 patients with AEH. The distribution of molecular classification was as follows: 157 cases (91.8%) were classified as having no specific molecular profile (NSMP); 9 cases (5.3%), mismatch repair deficient (MMR-d); 3 cases (1.8%), POLE-mutated; 2 cases (1.2%), p53 abnormal. No difference was found in the cumulative 40-week complete response (CR) rate between the patients having NSMP or MMR-d (61.6% vs 60.0%; P=0.593), while the patients having MMR-d had increased risk than those having NSMP to have recurrence after CR (50.0% vs 14.4%; P=0.005). Multi-variant analysis showed PTEN gene multi-loci mutation (HR=0.413, 95%CI: 0.259-0.658; P<0.001) and PIK3CA gene mutation (HR=0.499, 95%CI: 0.310-0.804; P=0.004) were associated with a lower cumulative 40-week CR rate, and progestin-insensitivity (HR=3.825, 95%CI: 1.570-9.317; P=0.003) and MMR-d (HR=9.014, 95%CI: 1.734-46.873; P=0.009) were independent risk factors of recurrence in EC and AEH patients. Conclusions: No difference in cumulative 40-week CR rate is found in the patients having NSMP or MMR-d who received progestin-based fertility-preserving treatment, where the use of hysteroscopy during the treatment might be the reason, while those having MMR-d have a higher risk of recurrence after CR. Oncogene mutation of PTEN or PIK3CA gene might be associated with a lower response to progestin treatment. The molecular profiles help predict the fertility-preserving treatment outcomes in EC and AEH patients.

Hypertension is a risk factor for a variety of cardiovascular diseases, which is an important public health problem in the world today. MiRNAs are a class of highly conserved non-coding small RNAs. In recent years, studies have found that miRNAs are involved in the occurrence and development of hypertension through a variety of ways, causing damage to the important target organs of hypertension, such as heart, brain and kidney. This article reviews the research progress of miRNA in hypertension in recent years, in order to clarify its role in the process of hypertension and target organ damage, and provide ideas for exploring new therapeutic targets of hypertension.
摘要
Objective: To explore the epidemiological characteristic of a COVID-19 outbreak caused by 2019-nCoV Omicron variant BF.7 and other provinces imported in Shenzhen and analyze transmission chains and characteristics. Methods: Field epidemiological survey was conducted to identify the transmission chain, analyze the generation relationship among the cases. The 2019-nCoV nucleic acid positive samples were used for gene sequencing. Results: From 8 to 23 October, 2022, a total of 196 cases of COVID-19 were reported in Shenzhen, all the cases had epidemiological links. In the cases, 100 were men and 96 were women, with a median of age, M (Q1, Q3) was 33(25, 46) years. The outbreak was caused by traverlers initial cases infected with 2019-nCoV who returned to Shenzhen after traveling outside of Guangdong Province.There were four transmission chains, including the transmission in place of residence and neighbourhood, affecting 8 persons, transmission in social activity in the evening on 7 October, affecting 65 persons, transmission in work place on 8 October, affecting 48 persons, and transmission in a building near the work place, affecting 74 persons. The median of the incubation period of the infection, M (Q1, Q3) was 1.44 (1.11, 2.17) days. The incubation period of indoor exposure less than that of the outdoor exposure, M (Q1, Q3) was 1.38 (1.06, 1.84) and 1.95 (1.22, 2.99) days, respcetively (Wald χ2=10.27, P=0.001). With the increase of case generation, the number and probability of gene mutation increased. In the same transmission chain, the proportion of having 1-3 mutation sites was high in the cases in the first generation. Conclusions: The transmission chains were clear in this epidemic. The incubation period of Omicron variant BF.7 infection was shorter, the transmission speed was faster, and the gene mutation rate was higher. It is necessary to conduct prompt response and strict disease control when epidemic occurs.

OBJECTIVE@#To investigate the mechanism by which Chinese medicine Shengmai Yin (SMY) reverses epithelial-mesenchymal transition (EMT) through lipocalin-2 (LCN2) in nasopharyngeal carcinoma (NPC) cells CNE-2R.@*METHODS@#Morphological changes in EMT in CNE-2R cells were observed under a microscope, and the expressions of EMT markers were detected using quantitative real-time PCR (RT-qPCR) and Western blot assays. Through the Gene Expression Omnibus dataset and text mining, LCN2 was found to be highly related to radiation resistance and EMT in NPC. The expressions of LCN2 and EMT markers following SMY treatment (50 and 100 µ g/mL) were detected by RT-qPCR and Western blot assays in vitro. Cell proliferation, migration, and invasion abilities were measured using colony formation, wound healing, and transwell invasion assays, respectively. The inhibitory effect of SMY in vivo was determined by observing a zebrafish xenograft model with a fluorescent label.@*RESULTS@#The CNE-2R cells showed EMT transition and high expression of LCN2, and the use of SMY (5, 10 and 20 µ g/mL) reduced the expression of LCN2 and reversed the EMT in the CNE-2R cells. Compared to that of the CNE-2R group, the proliferation, migration, and invasion abilities of SMY high-concentration group were weakened (P<0.05). Moreover, SMY mediated tumor growth and metastasis in a dose-dependent manner in a zebrafish xenograft model, which was consistent with the in vitro results.@*CONCLUSIONS@#SMY can reverse the EMT process of CNE-2R cells, which may be related to its inhibition of LCN2 expression. Therefore, LCN2 may be a potential diagnostic marker and therapeutic target in patients with NPC.

Objective:To investigate the clinical characteristics and prognostic factors of 2019 novel coronavirus (2019-nCoV) Omicron variant infected cases.Methods:A total of 987 coronavirus disease 2019 (COVID-19) adult imported cases admitted to Shanghai Public Health Clinical Center, Fudan University from July 1, 2021 to January 6, 2022 were recruited. The cases were divided into Omicron group (193 cases) and non-Omicron group (794 cases) according to the genotype of the virus. The clinical data, imaging examination and laboratory results of two groups were collected and compared. Chi-square test and Mann-Whitney U test were used as statistical methods. Multiple linear regression analysis was used for multiple linear regression analysis. Results:The majority of patients in Omicron group were 18 to 30 years old, accounting for 51.3%(99/193), which was higher than 31.4%(249/794) in non-Omicron group. The difference was statistically significant ( χ2=52.75, P<0.001). The proportion of mild cases in Omicron group was 88.6%(171/193), which was higher than 81.6%(648/794) in non-Omicron group. The difference was statistically significant ( χ2=5.37, P=0.021). Cases with symptoms were more common in Omicron group than those in non-Omicron group (60.1%(116/193) vs 29.1%(231/794)), and the difference was statistically significant ( χ2=65.49, P<0.001), with the main clinical manifestations of sore/itchy throat, fever and cough/expectoration. The proportion of cases with pulmonary computed tomography (CT) imaging manifestations at admission in Omicron group was 13.0%(25/193), which was lower than that in non-Omicron group (215/794, 27.1%). The difference was statistically significant ( χ2=16.83, P<0.001). The proportion of cases with 2019-nCoV IgG positive at admission was 47.7%(92/193) in Omicron group, which was lower than 61.1%(485/794) in non-Omicron group, and the difference was statistically significant ( χ2=11.51, P<0.001). The hospitalization time of Omicron group was 20.0 (16.0, 23.0) d, which was longer than that of non-Omicron group (14.0 (10.0, 22.0) d), and the difference was statistically significant ( Z=-7.42, P<0.001). Multiple linear regression analysis showed that the time of hospitalization of cases with 2019-nCoV IgG positive at admission was shorter, while that of the cases with fever in Omicron group was longer (both P<0.050). Conclusions:The main clinical characteristics of cases with Omicron variant are fever and upper respiratory symptoms. Their pulmonary CT imaging manifestations are less, and the time of hospitalization is slightly longer. The time of hospitalization and the virus clearance time in Omicron variant infected cases with 2019-nCoV IgG positive at admission and not presented with fever are both shorter.
摘要
Objective To investigate the efficacy of endoscopic ligation combined with traditional Chinese medicine (TCM) syndrome differentiation-based treatment in the secondary prevention of esophageal variceal bleeding (EVB) in patients with liver cirrhosis. Methods A total of 108 EVB patients who were admitted to Department of Liver Cirrhosis, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from April 2015 to February 2021 and underwent endoscopic ligation were enrolled, among whom 59 patients with TCM treatment were enrolled as Chinese and Western medicine group, and 49 patients without TCM treatment were enrolled as Western medicine group. The two groups were compared in terms of the incidence rate of rebleeding, mortality rate, and the improvement rate of portal hypertensive gastropathy. The t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups; a Cox regression analysis was used to evaluate the risk factors for rebleeding. Results Compared with the Western medicine group, the Chinese and Western medicine group had a significantly lower rebleeding rate within 13-24 months after ligation (2% vs 12%, P =0.045), a significantly lower mortality rate of rebleeding (2% vs 12%, P =0.045), and a significantly higher overall response rate of portal hypertensive gastropathy (90% vs 77%, P =0.04). Underlying diseases (mainly including diabetes, hypertension, and heart disease) and Child-Pugh class for liver function were significant risk factors for rebleeding (all P < 0.05). Conclusion Ligation combined with TCM treatment can significantly reduce the incidence rate of delayed rebleeding and the mortality rate of EVB and improve the degree of portal hypertensive gastropathy, which provides a new strategy for ligation combined with TCM treatment to improve the overall response of EVB secondary prevention.

Clinical data of 26 patients with proton pump inhibitor dependent gastroesophageal reflux disease (GERD) who underwent anti-reflux mucosectomy (ARMS) in Nanjing Drum Tower Hospital from July 2017 to December 2020 were reviewed, and the GERD questionnaire (GERD-Q) score, the short-form reflux-qual (RQS) score, esophageal motility and 24 h esophageal pH parameters before and after ARMS were compared. With a median follow-up period of 18.4 months (6-27 months), 23 (88.5%) patients reported symptomatic improvement and 15 (57.7%) patients discontinued the use of proton pump inhibitors. After ARMS, the mean scores of GERD-Q (6.23 VS 13.19, P=0.004) and RQS (26.67 VS 10.98, P<0.001) were significantly improved, the mean DeMeester score (10.69 VS 53.15, P<0.001), the mean acid exposure time percentage (3.56% VS 9.92%, P<0.001) and the mean number of acid reflux episodes (36.9 VS 139.9, P=0.001) were lower, and the mean rest pressure at lower esophageal sphincter (LES) (25.19 mmHg VS 13.63 mmHg, P<0.001) and the mean distal contractile integral (1 819.15 mmHg·s·cm VS 1 007.67 mmHg·s·cm, P<0.001) were significantly increased compared with those before surgery. ARMS has significant short-term efficacy in the treatment of proton pump inhibitor dependent GERD, which can effectively improve reflux symptoms and life quality of patients, and strengthen the rest pressure of LES and peristalsis of the esophageal body.

Objective:To analyze the clinicopathological characteristics of differentiated early cardia cancer and to evaluate the short-term and long-term efficacy of endoscopic submucosal dissection (ESD).Methods:A total of 329 patients (331 lesions) who underwent ESD at Nanjing Drum Tower Hospital from October 2014 to December 2019 and were pathologically confirmed as differentiated early cardia cancer were included in the study and followed up. The endoscopic and pathological data of patients were reviewed to analyze the clinicopathological characteristics of differentiated early cardia cancer. The short-term (including en bloc resection rate, curative resection rate and incidence of short-term complications) and long-term efficacy (including incidence of metachronous cancer, recurrence and distant metastasis, and overall survival rate) of ESD was evaluated.Results:The ratio of male to female in 329 patients with differentiated early cardia cancer was 4∶1, and their age was 65.69±8.02 years. Tumor diameter of ≤2.0 cm accounted for 65.9% (218/331). Most lesions were located on the posterior wall (50.5%, 167/331), followed by the minor curve (36.3%, 120/331). The endoscopic morphology of 0-Ⅱc type accounted for 49.5% (164/331). There were 69.8% (231/331) lesions confined to the mucosal layer. The en bloc resection rate was 100.0% (329/329), and the curative resection rate was 83.3% (274/329). Short-term complications occurred in 28 patients (8.5%). With a median follow-up time of 39 months, 11 patients (3.3%) developed metachronous cancer, 2 (0.6%) developed distant metastasis, and no recurrence occurred. Seven patients died, and the overall survival rate during the follow-up period was 97.9% (322/329). The survival rate of patients with curative resection and additional surgery was 100.0% (3/3), while that without additional surgery was 99.3% (269/271). The survival rate of patients with non-curative resection and additional surgery was 96.0% (24/25), and that without additional surgery was 86.7% (26/30).Conclusion:Most differentiated early cardia cancers are well-differentiated adenocarcinomas, with less than 2 cm in diameter at the time of diagnosis with a low rate of ulcer and vascular invasion. ESD is safe and effective for the treatment of differentiated early cardia cancer with a high rate of curative resection, fewer intraoperative and postoperative complications, low incidences of metachronous cancer, distant metastasis and recurrence, and a high overall survival rate. However, additional surgical treatment is recommended for patients with non-curative resection.

Objective:To evaluate the safety and feasibility of double endoscopic bypass, namely endoscopic ultrasound-guided gastroenterostomy (EUS-GE) combined with endoscopic ultrasound-guided biliary drainage (EUS-BD), for malignant gastric outlet and biliary obstruction.Methods:A retrospective analysis was conducted on data of 10 patients with malignant gastric outlet and biliary obstruction who were not suitable for surgery or endoscopic retrograde cholangiopancreatography (ERCP) and treated by double endoscopic bypass in Nanjing Drum Tower Hospital from August 2017 to October 2020. The completion of therapy, clinical efficacy and post-procedure adverse events were analyzed.Results:Ten patients with different malignant cancer successfully underwent EUS-GE and EUS-BD, with procedure time of 60.5±22.3 min (30-100 min). There were no postoperative adverse events. EUS-GE was clinically successful in all 10 cases. Of the 10 EUS-BD cases, 9 were clinically successful, and 1 did not meet the criteria of clinical success. The median follow-up was 71 (37-120) days. None of the 10 patients had recurrent gastric outflow tract obstruction or biliary tract obstruction.Conclusion:Double endoscopic bypass is feasible and effective for patients with malignant gastric outlet and biliary obstruction and without surgery or ERCP opportunity.

Objective:To develop an online interactive cytopathological training program, and to evaluate it for improving the cytopathological diagnostic ability of endoscopists in endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreas.Methods:A total of 5 500 cytopathological images were collected from 194 patients with pancreatic solid mass who underwent EUS-FNA in Nanjing Drum Tower Hospital from August 2018 to August 2019. The cell type in each cytopathological picture was labeled by senior cellular pathologists, which was used to build a learning and testing platform for online interactive cytopathological training. Five endoscopists without cytopathological background were invited to participate in this training. Sensitivity, specificity, positive predictive value and negative predictive value of endoscopists in differential diagnosis of cancer and non-cancer before and after training were compared to evaluate the effect of the online interactive cytopathological training program on improving the ability of endoscopists in diagnosis of cytopathology.Results:A cytopathological training platform for endoscopists to learn and take online test was successfully built. Before training, sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnosis of cancer and non-cancer for endoscopists were 0.55 (95% CI: 0.53-0.58), 0.32 (95% CI: 0.30-0.35), 0.43 (95% CI: 0.41-0.45), 0.44 (95% CI: 0.41-0.47) and 0.43 (95% CI: 0.42-0.45), respectively. After training, the above indicators were 0.96 (95% CI: 0.95-0.97), 0.70 (95% CI: 0.68-0.73), 0.74 (95% CI: 0.72-0.76), 0.95 (95% CI: 0.94-0.96) and 0.81 (95% CI: 0.80-0.83), respectively, which were significantly improved compared with those before ( P<0.001). Conclusion:The online interactive cytopathological training program can improve the understanding and diagnostic ability of endoscopists in pancreatic cytopathology, help to implement rapid on-site evaluation in the process of EUS-FNA, and improve the diagnostic efficiency of EUS-FNA.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for early hypopharyngeal carcinoma and precancerous lesions.Methods:Clinical data of 41 patients who received ESD for early hypopharyngeal carcinoma and precancerous lesions from August 2013 to August 2019 in the Department of Endoscopy of Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were retrospectively analyzed. Main outcome measurements included operation completion rate, operation time, en bloc resection rate, R0 resection rate, complication rate and recurrence.Results:ESD was successfully completed in all 41 cases, with a success rate of 100.0% and a mean time of 49.1 min (ranged 10-110 min). Fifty-four lesions underwent en bloc resection, with an en bloc resection rate of 98.2% (54/55), of which 41 had negative horizontal and vertical margins, and the R0 resection rate was 74.5% (41/55). During the operation of 55 lesions, there was a small amount of blood oozing on the wound surface, and electrocoagulation with thermal biopsy forceps could successfully stop the bleeding. No perforation occurred, and 2 cases (4.3%) had delayed bleeding after ESD, and hemostasis was successful under emergency endoscopy. Postoperative endoscopy showed that 1 case (2.2%) had esophageal entrance stenosis, and the obstruction was relieved after repeated water balloon dilatation. The follow-up period ranged from 3 to 72 months, and the median time was 18 months. One case was found to have mucosal lesions in the same part of the hypopharynx and received ESD treatment again. Follow-up to October 2020, no residual lesions and recurrence were found.Conclusion:ESD is a safe and effective option for the treatment of early hypopharyngeal carcinoma and precancerous lesions, which is worthy of clinical application.

Objective:To study the safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cardia cancer (EGCC) in elderly patients.Methods:A retrospective analysis was performed on data of 499 EGCC patients who underwent ESD from January 2011 to June 2018 in Nanjing Drum Tower Hospital. The patients were divided into two groups by age, the young/middle-aged group (<65 years old) and the elderly group (≥65 years old). The baseline data, lesion features, postoperative complications, short-term efficacy and long-term efficacy of the two groups were compared.Results:The elderly group included 272 patients (283 lesions) and the young/middle-aged group included 227 patients (229 lesions). Except that there were significant differences in the age ( P<0.001) and body mass index ( P=0.002) between the elderly group and the young/middle-aged group, there were no significant differences in the baseline data or pathological features between the two groups. The rate of curative resection in the elderly group was 77.0%, lower than that in the young/middle-aged group (84.3%, P=0.045). No significant differences were found in en bloc resection rate (100.0% VS 99.6%, P=1.000), complete resection rate (94.7% VS 93.9%, P=0.705), postoperative complications incidence (6.4% VS 5.7%, P=0.747), operation time (64.02±39.24 min VS 66.16±44.62 min, P=0.566) or hospitalization time (6.76±2.06 d VS 6.47±1.74 d, P=0.092]. After the median follow-up of 47.9 months, 13.4% patients in the elderly group received additional surgery, which was slightly lower than that in the young/middle-aged group ( P=0.891). There were no significant differences in postoperative recurrence, lymph node metastasis, distant metastasis, overall mortality and disease-related mortality between the two groups. The survival analysis showed that five-year overall survival rates were 94.41% and 96.34% in the elderly group and the young/middle-aged group respectively ( P=0.156), and five-year disease-specific survival rate were 99.18% and 99.03% in the two groups respectively ( P=0.858). Conclusion:ESD is safe and effective for EGCC in elderly patients with satisfactory short-term and long-term efficacy.

ObjectiveTo analyze the status of depression with somatization symptoms among college students during the pandemic of COVID-19， and to screen the influencing factors. MethodsFrom 12 to 19 March 2020， all the 2019 freshmen in Communication University of China， Nanjing completed a web-based survey， in which all the students were assessed by Psychological Questionnaires for Emergent Events of Public Health （PQEEPH）， somatization subscale of Symptom Checklist 90 （SCL-90）， Self-rating Depression Scale （SDS） and self-designed general demographic questionnaire， then the collected data were processed by univariate and multivariate Logistic regression. ResultsA total of 3 406 valid questionnaires were collected， with an effective recovery rate of 93.0%. The detection rate of depression symptoms and depression with somatization symptoms were 55.7% （1 898/3 406） and 4.9% （93/1 898）， respectively. Logistic regression analysis showed that single parent family （OR=2.977， P<0.01）， score of neurasthia dimension in PQEEPH （OR=3.693， P<0.01）， score of obsessive-anxiety dimension in PQEEPH （OR=6.794， P=0.001）， depression of moderate degree （OR=1.788， P=0.065）， and depression of severe degree （OR=4.462， P=0.003） were risk factors for depression with somatization symptoms of college students during the COVID-19 pandemic. ConclusionDuring the COVID-19 pandemic， a certain proportion of college students suffer from depression with somatization symptoms， furthermore， obsessive-anxiety， neurasthenia， moderate-to-severe depression and single parent family are the risk factors of depression with somatization symptoms among college students.
