Arsenic (As) is a common toxic pollution element. The microorganism-mediated transformation of arsenic forms is an important part in the biogeochemical cycle of As. In the various microbial metabolic processes involving As, the coupling reduction of As has a great impact on the environment and is a process that is easily overlooked.

Methods: All patients who received surgical treatment for esophageal cancer at SCH in 2017 were given a detailed summary of clinical information based on the database of SCH.
Background: The interim analysis of the randomized phase 3 ESCORT-1st study demonstrated significantly longer overall survival (OS) and progression-free survival (PFS) for camrelizumab-chemotherapy than placebo-chemotherapy in untreated advanced/metastatic esophageal squamous cell carcinoma (ESCC). Here, we present the final analysis of this study and investigate potential indicators associated with OS.
Methods: Patients were randomized 1:1 to receive camrelizumab (200 mg) or placebo, both in combination with up to six cycles of paclitaxel (175 mg/m) and cisplatin (75 mg/m).
For most patients with advanced thymic epithelial tumors (TETs), a complete resection is a strong indicator of a better prognosis. But sometimes, primary surgery is unsatisfactory, and preoperative therapy is needed to facilitate complete resection. Neoadjuvant chemotherapy is the most used form of preoperative therapy.

This study explored the use of internal jugular vein pressure (IJVP) monitoring to guide the SVC reconstruction strategy.
Methods: In a retrospective cohort, perioperative outcomes of unilateral and bilateral reconstruction based on surgeons' experience were compared.

Excessive levels of cadmium (Cd) in soil exert serious negative impacts on soil ecosystems. Microorganisms are a common component of soil and show great potential for mitigating soil Cd. This review summarizes the application and remediation mechanisms of microorganisms, microbial-plants, and microbial-biochar in Cd-contaminated soil.

In this experiment, we comprehensively evaluated the adsorption of Mn(II) by biochar with different modification methods from different biomass. The biochar from rice straw, coconut shell, and bamboo was produced by pyrolysis at 600 °C under nitrogen and then modified with HNO, NaOH, and NaS, respectively.

Methods: Patients who underwent uniport subxiphoid video-assisted thoracoscopic surgery (USVATS) or unilateral video-assisted thoracoscopic surgery (LVATS) from September 2018 to December 2021 were retrospectively enrolled in this study.
Background: Esophageal cancers present a significant burden of disease and remain one of the most lethal of cancers worldwide, particular in China. Surgical treatment remains the cornerstone of esophageal cancers, and a real-world data from a high-volume esophageal cancer center have guiding significance in evaluation of the current clinical practice. This report describes the clinical characteristics, treatment outcomes, and survival of surgical treatment in patients with esophageal cancer in Shanghai Chest Hospital (SCH).

Methods: The clinical data of consecutive patients with stage T2-3NxM0 (eighth edition TNM staging) thymic malignancies who underwent MIT or MST were identified from a prospectively maintained database.
Background: The outcomes of locally advanced non-small cell lung cancer (LA-NSCLC) are unfavorable mainly due to a high risk of cancer recurrence. Only around 5% of patients can benefit from perioperative chemotherapy which is the current standard treatment. Recently, promising results with neoadjuvant targeted and immune-therapy therapy have been seen.
View Article and Find Full Text PDFObjectives: The prognosis of patients with locally advanced esophageal squamous cell carcinoma with different recurrence backgrounds is highly heterogeneous. This study aims to explore the effects of recurrence patterns on prognosis.
Methods: The phase III, multicenter, prospective NEOCRTEC5010 trial enrolled 451 patients with stage IIB-III esophageal squamous cell carcinoma randomly assigned to neoadjuvant chemoradiotherapy combined with surgery (NCRT group) or surgery alone (S group) and followed them long-term.
Objectives: With increasing use of CT screening for lung cancers, there is a tendency toward increased detection of asymptomatic small anterior mediastinal nodules (SAMNs). In face of high rate of non-therapeutic surgery in these patients, workup and follow-up strategy for such lesions remains to be established.
Materials And Methods: This is a real-world study in patients with SAMNs (baseline diameter ≤ 3 cm) during 2013-2018.
Background: Few studies have exclusively investigated the value of pathological complete response (pCR), in esophageal squamous cell carcinoma (ESCC) patients, although it is a clinically significant parameter to evaluate the impact of neoadjuvant chemoradiotherapy (nCRT) on treatment outcome after surgery. The aim of our study was to explore the relationship between pCR after nCRT and survival among patients with local ESCC.
Methods: All patients receiving nCRT followed by surgery in NEOCRTEC5010-trial (NCT01216527) were included.
Importance: Standard first-line therapy for advanced or metastatic esophageal carcinoma is chemotherapy, but the prognosis remains poor. Camrelizumab (an anti-programmed death receptor 1 [PD-1] antibody) showed antitumor activity in previously treated advanced or metastatic esophageal squamous cell carcinoma.
Objective: To evaluate the efficacy and adverse events of camrelizumab plus chemotherapy vs placebo plus chemotherapy as a first-line treatment in advanced or metastatic esophageal squamous cell carcinoma.
Importance: The prognosis of patients with locally advanced esophageal squamous cell carcinoma (ESCC) remains poor after surgery. Neoadjuvant chemoradiotherapy (NCRT) has been shown to potentially improve survival.
Objective: To compare the treatment efficacy of NCRT plus surgery with surgery alone for long-term survival among patients with locally advanced ESCC.
Objective: To clarify whether systemic LND influences the safety of surgery and the survival of patients with locally advanced esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemoradiotherapy (nCRT).
Summary Of Background Data: Prognostic impact of systemic lymphadenectomy during surgery after nCRT for ESCC is still uncertain and requires clarification.
Methods: This is a secondary analysis of NEOCRTEC5010 trial which compared nCRT followed by surgery versus surgery alone for locally advanced ESCC.
Background: We analyzed the pathological characteristics and recurrence pattern of cN0 submucosal esophageal cancer after esophagectomy and conducted risk stratification to determine the feasibility of performing endoscopic resection for cN0pT1b esophageal squamous cell malignancies.
Methods: We retrospectively enrolled 167 patients who underwent right-sided transthoracic esophagectomy and extended thoracic/abdominal two-field lymphadenectomy. Patients with pathologically confirmed lymph node metastasis or tumor recurrence constituted the high-risk group for endoscopic submucosal resection, and the remainder were defined as low risk.
Objective: To determine the prognostic impact of pathologic lymph node (LN) status and investigate risk factors of recurrence in esophageal squamous cell carcinoma (ESCC) patients with pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (NCRT).
Summary Background Data: There are no large-scale prospective study data regarding ypN status and recurrence after pCR in ESCC patients receiving NCRT.
Methods: The NEOCRTEC5010 trial was a prospective multicenter trial that compared the survival and safety of NCRT plus surgery (S) with S in patients with locally advanced ESCC.
Objective: Our aim was to investigate appropriate postoperative management based on the risk of disease recurrence in thymic epithelial tumors after complete resection.
Methods: The Chinese Alliance for Research in Thymomas retrospective database was reviewed. Patients having stage I to IIIa tumors without pretreatment and with complete resection were included.
Pulmonary echinococcosis is a zoonotic parasitic disease caused by the larval stage of cestodes belonging to the genus echinococcus, which is the top killer of residents in pastoral areas and requires more attention. Prevention is the top priority; screening is another important strategy. Surgery is still the preferred treatment for pulmonary echinococcosis.

For patients without lymph nodes metastasis, the role of adjuvant therapy is uncertain. This study was intended to retrospectively analyze the survival effects of postoperative adjuvant therapy in such patients.
