Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:To retrospectively analyze the independent risk factors of complicated appendicitis(CA)in children under five years old and establish a clinical prediction model, and to evaluate the clinical application of this model.Methods:A retrospective analysis was performed on children under five years old who underwent appendectomy at Children′s Hospital of Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021.The children were divided into CA group and uncomplicated appendicitis group according to whether there was sign of perforation or gangrene in appendiceal tissue after operation.The differences in clinical features and preoperative laboratory test results between two groups were compared.The independent risk factors of CA were identified and a clinical prediction model was established.The clinical prediction model was verified by receiver operating characteristic curve.Results:A total of 140 children were enrolled in this study, including 84 cases in the CA group and 56 cases in uncomplicated appendicitis group.Univariate and binary Logistic regression analysis showed that the duration of symptoms>23.5 h( OR=6.650, 95% CI 2.469-17.912, P<0.05), abdominal muscle tension( OR=3.082, 95% CI 1.190-7.979, P<0.05) and C-reactive protein>41 mg/L ( OR=3.287, 95% CI 1.274-8.480, P<0.05) were independent risk factors for CA( P<0.05). The clinical prediction model of CA was constructed by the above mentioned three independent risk factors.The area under the receiver operating characteristic curve of the clinical prediction model was 0.881(95% CI 0.825-0.936), the sensitivity was 77.4%, the specificity was 87.5%, the positive predictive value was 91.3% and the negative predictive value was 70.0%. Conclusion:Acute appendicitis in children under five years old is more likely to progress to CA if the duration of symptoms>23.5 h, the level of C-reactive protein is increased, and the abdominal muscle tension is accompanied.The clinical prediction model of CA constructed by common clinical information in pediatric clinics has good prediction efficiency, which provides a simple and feasible reference method for clinicians to distinguish CA from uncomplicated appendicitis.

Objective:To establish a decision tree model of pediatric complicated appendicitis (CA) based on Pediatric Appendicitis Score (PAS) combined with inflammatory indicators, and to evaluate its clinical application efficacy in pediatrics.Methods:The clinical data of 544 children diagnosed with appendicitis in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021 was retrospectively analyzed. According to postoperative pathology, the children were divided into uncomplicated appendicitis group and CA group. The independent risk factors of CA were screened by univariate and multivariate logistic regression analysis, and these parameters were included to establish the decision tree model. The accuracy of the decision tree model was verified by receiver operating characteristic (ROC) curve.Results:Binary logistic regression analysis indicated that the PAS, C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) were identified as independent risk factors for complicated appendicitis in children (all P<0.05). PAS, CRP and NLR were included as covariables to construct the decision tree model and binary logistic regression model for predicting CA. The decision tree demonstrated an overall accuracy of 79.2% with a sensitivity of 86.7% and specificity of 71.9%, and achieved an area under curve (AUC) of 0.821(95% CI: 0.786-0.857). The binary logistic regression model had a sensitivity of 79.6% and specificity of 69.1%, with an overall accuracy of 75.1% and achieved an AUC of 0.808(95% CI: 0.770-0.845). Conclusions:The decision tree model based on PAS score combined with CRP, NLR is a simple, intuitive and effective tool , which can provide pediatric emergency physicians a reliable basis for diagnosis of pediatric CA.

OBJECTIVE To monitor the occurrence of tenofovir disoproxil fumarate （TDF）-induced kidney injury and investigate the risk factors， and provide reference for rational use of TDF in clinic. METHODS The information of inpatients with hepatitis B was collected by China Hospital Pharmacovigilance System （CHPS） from the Second People’s Hospital of Lanzhou during Jan. 1st， 2019 to Dec. 31st 2021. The search criteria were set according to kidney injury criteria， and suspected TDF- induced kidney injury cases were actively monitored； then the clinical pharmacist confirmed the positive patients with TDF-induced kidney injury one by one and calculated the incidence of TDF-induced renal injury； the risk factors for TDF-induced kidney injury in real world were explored by collecting and analyzing the correlation of basic data of patients， main indexes of liver and kidney function， complications and combined use of drugs with TDF-induced renal indexes. RESULTS Totally 1 226 inpatients with hepatitis B using TDF were included. Through active monitoring of CHPS， 160 suspected patients with TDF-induced kidney injury were found， and 64 positive patients were finally confirmed manually. The incidence of TDF-induced kidney injury was 5.22%. Compared with pre-medication， the levels of serum creatinine and cystatin C， the proportion of patients with urinary protein 2+ and above were increased significantly after medication （P＜0.001）， glomerular filtration rate and blood phosphorus level were reduced significantly （P＜0.001） and other indicators had no statistical difference. Treatment time for more than 36 months， disease progresses to decompensated cirrhosis， and concomitant use of more than 10 kinds of drugs were significantly correlated with TDF- related kidney injury （P＜0.05 or P＜0.012 5）. CONCLUSIONS The active monitoring scheme of TDF-induced kidney injury established by CHPS has the characteristics of time-saving， labor-saving and high efficiency； based on real-world evidence， it is imperative to strengthen monitoring kidney function of patients when using TDF， especially when the patient has been on medication for a long time， in decompensated cirrhosis and combination of multiple drugs， and thus， we can identify earlier and avoid adverse effects in high-risk patientseffectively.

Objective:To observe the clinical efficacy of endoscopic submucosal dissection (ESD) in the treatment of superficial esophageal cancer (SEC), and to explore the application value of ESD in the treatment of SEC.Methods:From January 2016 to December 2019, at The First Affiliated Hospital With Nanjing Medical University, the clinical data of 368 patients with SEC and receiving ESD treatment were retrospectively analyzed, induding the general condition, the circumferential proportion of lesions, effectiveness of ESD treatment (en bloc resection rate, complete resection rate, curative resection rate, operation time and resected lesion area), incidence of complications and follow-up. 368 patients were divided into stenosis group (94 cases) and non-stenosis group (274 cases) according to the occurrence of esophageal stenosis after ESD. The circumferential proportion of lesions, operation time and resected lesion area were compared between stenosis group and non-stenosis group, and the independent risk factors of esophageal stenosis after ESD were analyzed. Independent sample t test, chi-square test and binary logistic regression analysis were used for statistical analysis. Results:Among 368 patients, 270(73.4%) were male and 98 (26.6%) were female; the age was (64.4±7.6) years old. The circumferential proportion of lesions of 231 cases (62.8%) was <1/2 circle, 49 cases (13.3%) was 1/2 to <2/3 circle, and 88 cases (23.9%) was ≥2/3 circle. The en bloc resection rate of the lesion was 98.6%(363/368), the complete resection rate and curative resection rate were both 97.8% (360/368). The operation time was (89.4±47.9) min. The area of resected lesion was (12.5±8.9) cm 2. The incidence of perforation during operation, delayed bleeding and stenosis was 0.3% (1/368), 0.5% (2/368) and 25.5% (94/368), respectively. The followed-up period was 8 to 53 months, and the median follow-up period was 25 months. During the follow-up period, no recurrence or new lesion was found, and no lymph node or distant metastasis occurred. The circumferential proportion of lesions of 38 cases (40.4%) of stenosis group and 193 cases (70.4%) of non-stenosis group was <1/2 circle, respectively, the circumferential proportion of lesions of 9 cases (9.6%) and 40 cases (14.6%) was 1/2 to <2/3 circle, respectively, the circumferential proportion of lesions of 47 cases (50.0%) and 41 cases (15.0%) was ≥2/3 circle, respectively, and the difference was statistically significant ( χ2=47.30, P<0.01). The operation time of stenosis group was longer than that of non-stenosis group, the resected lesion area was larger than that of non-stenosis group ((126.1±56.3) min vs. (76.8±37.2) min, (17.5±10.7) cm 2 vs. (10.8±7.4) cm 2), and the differences were statistically significant ( t=9.57 and 5.41, both P<0.01). The results of binary logistic regression analysis showed that circumferential proportion of lesions ≥2/3 circle, operation time and the resected lesion area were independent risk factors for the occurrence of esophageal stenosis after ESD (odds ratio=0.253, 1.018 and 1.041, 95% confidence interval 0.116 to 0.551, 1.011 to 1.025, 1.007 to 1.076, all P<0.05). Conclusions:ESD is a safe and effective way to treat SEC, with low local recurrence rate and few complications, which is worthy of further clinical promotion.

Objective:To investigate the effect of Qingre-Tongfu enema combined with noninvasive positive pressure ventilation on the ventilation function of elderly patients with severe pneumonia. Methods:A total of 60 elderly patients with severe pneumonia with syndrome of excess of Yangming fushi from September 2017 to August 2019 in the respiratory department of the First People’s Hospital of Dongcheng District, Beijing were randomly divided into two groups, 30 cases in each group. The control group was treated with western medicine to control infection and noninvasive positive pressure ventilation. The treatment group was treated with Qingre-Tongfu enema on the basis of the control group. The Traditional Chinese Medicine Syndrome score (TCMSSS), Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE-Ⅱ) and Clinical Pulmonary Infection Score (CPIS) were compared before and after treatment, The Pneumonia Severity Index (PSI) was compared. Serum procalcitonin (PCT) was detected by upconversion luminescence immunoassay, CRP was detected by double antibody sandwich ELISA, WBC was detected by automatic hematology analyzer; partial pressure of carbon dioxide (PaCO 2), oxygen saturation (SaO 2), partial pressure of oxygen (PaO 2) were detected by blood gas analyzer, oxygenation index (OI) and respiratory rate (RR) were calculated. The complications were investigated and the clinical efficacy was evaluated. Results:The total effective rate was 96.7% (29/30) in the treatment group and 73.3% (22/30) in the control group, with significant difference between the two groups ( χ2=4.706, P=0.030). After treatment, the levels of serum PCT, CRP and WBC in the treatment group were significantly lower than those in the control group ( t=15.359, 25.784 and 13.460, respectively, P<0.01); after treatment, the levels of SaO 2 [(93.18 ± 3.79)% vs. (88.78 ± 5.56)%, t=3.584], PaO 2 [(86.81 ± 4.01) mmHg vs. (80.01 ± 4.76) mmHg, t=5.975], OI [(285.53 ± 15.05) mmHg vs. (227.65 ± 12.37) mmHg, t=16.272] in the treatment group significantly were higher than those in the control group ( P<0.01); PaCO 2 [(43.28 ± 6.84) mmHg vs. (48.83 ± 7.66) mmHg, t=-2.956], RR [(22.00 ± 3.79) times/min vs. (26.30 ± 3.73) times/min, t=-4.434] in the treatment group were significantly lower than those in the control group ( P<0.05). After treatment, the scores of TCMSSS, APACHE-Ⅱ, CPIS and PSI in the treatment group were significantly lower than those in the control group ( t=41.310, 11.035, 8.399, 5.752, P<0.01). The treatment group in the course of antibiotics, mechanical ventilation time, hospital stay were significantly shorter than the control group ( P<0.01). Conclusion:Qingre-Tongfu enema combined with noninvasive positive pressure ventilation can improve the clinical symptoms of elderly patients with severe pneumonia, reduce inflammatory reaction, shorten the time of mechanical ventilation and antibiotic treatment, and improve the clinical efficacy.

Background: Esophageal mucosal injury induced by gastroesophageal reflux is a key link to the development of Barrett's esophagus-associated adenocarcinoma. However, the molecular mechanism is still not elucidated. Aims: To investigate the role of differentially expressed genes (DEGs) after stimulating esophageal cells with acid and bile acid in the development of esophageal adenocarcinoma (EAC). Methods: The DEGs were obtained through bioinformatics methods after stimulating esophageal cells with low pH and deoxycholic acid, and GO, KEGG enrichment analysis were performed. Protein-protein interaction (PPI) network was performed to screen the hub genes, and their relationships with prognosis and tumor stage of EAC patients were analyzed. The role of co-expressed genes of GADD45B in EAC was also analyzed. Results: Thirty-one overlapping DEGs were obtained after stimulating esophageal cells with low pH and deoxycholic acid, which mainly enriched in the cytokine-cytokine receptor interaction, transcription factors activity, and regulation of cell proliferation and apoptotic process. High expression of GADD45B was correlated with the survival prognosis and tumor stage of EAC patients. GADD45B and its co-expressed genes were involved in the production of tumor necrosis factor. Conclusions: The high expression of GADD45B induced by acid and bile acid is correlated with the prognosis and tumor stage of EAC patients, and is a potential diagnosis and treatment target for Barrett's esophagus-associated adenocarcinoma.

Objective:To understand changes in psychological resilience of nurses rushing to ICU in Wuhan under COVID-19 epidemics, and provide a theoretical basis for the psychological adjustment and psychological intervention of nurses in public health emergencies.Methods:Using phenomenological research method, the first batch of nurses from Nursing Department of Taizhou People's Hospital to assist Wuhan medical team in February 2020 were selected as the research objects based on Richardson psychological resilience model by the purposive sampling method. The diaries of 9 nurses who assisted Wuhan ICU were used as the original data, and the data collection time was based on the principle of data saturation. The data reached saturation after 18 days of rushing to Wuhan. A total of 9 nurses all completed the diary writing, with a total of approximately 28 452 words. The Colaizzi method was used to analyze the data and extract the topic.Results:A total of 3 first-level themes and 8 second-level themes were extracted, namely the stress period (intrusive thoughts, physical challenges, psychological distress) , buffer zone (psychological capital mobilization, team resilience stimulation, comprehension of social support) and restructuring period (balance restoration, self-transcendence) .Conclusions:Psychological resilience is not a constant psychological feature, but a constantly changing process in the game of destruction and reorganization. The psychological resilience of nurses rushing to ICU in Wuhan is in a dynamic process of stress-buffer zone-reorganization period, while enhancing team resilience and external support is conducive to the healthy development of the balance of psychological resilience of nurses who rushed to wuhan.
