Membrane contact sites (MCSs) are adjacent locations between the membranes of two different organelles and play important roles in various physiological processes, including cellular calcium and lipid signaling. In cancer research, MCSs have been proposed to regulate tumor metabolism and fate, contributing to tumor progression, and this function could be exploited for tumor therapy. However, there is little evidence on how MCSs are involved in cancer progression.

However, it is unclear whether patients without EGFR mutations cannot benefit from these drugs. Patient-derived tumor organoids (PDOs) are reliable tumor models that can be used in drug screening.

We aimed to compare the efficacy and safety of three enteral feeding strategies in patients with severe stroke.
Methods: The Optimizing Early Enteral Nutrition in Severe Stroke (OPENS) study was a multicentre, investigator-initiated, prospective, open-label, randomised controlled trial, with blinded outcome assessment, in 16 tertiary and district general hospitals in the west of China.
Background: Currently, thoracoscopic lobectomy is widely used in clinical practice, and postoperative placement of ultrafine drainage tube has advantages of reducing postoperative pain and accelerating postoperative recovery in patients. This study aimed to investigate the feasibility and safety of placement of 8F ultrafine chest drainage tube after thoracoscopic lobectomy and its superiority over traditional 24F chest drainage tube.
Methods: A retrospective data analysis was conducted in 169 patients who underwent placement of 8F ultrafine chest drainage tube or 24F chest drainage tube with thoracoscopic lobectomy for lung cancer from January 2018 to December 2019.
Background: Esophageal squamous cell carcinoma(ESCC) is one of the most common tumors worldwide. Esophagectomy with three-field lymph node dissection(3FLND) is the radical surgical procedure for esophageal cancer. However, 3FLND is not widely used due to it's higher mortality rate and higher incidence of postoperative complications.

In recent years, we have implemented new method for the treatment of intrathoracic esophagogastric anastomotic leak with the nasogastric placement of sump drainage tube through fistula into abscess cavity. The aim of this study is to compare the efficacy of the new method and conventional therapies for intrathoracic anastomotic leak after esophagectomy.

To reduce postoperative cardiopulmonary complications and promote postoperative recovery. We made an attempt to adopt the single-port inflatable mediastinoscopy combined with laparoscopy for radical esophagectomy in esophageal cancer to observe the clinical application and effect.

This study was undertaken to determine the role of miR-181b in chemo resistance of small cell lung cancer cells.

This is a subanalysis of patients from the China Status II study, aimed to evaluate the effectiveness and safety of valsartan/amlodipine (Val/Aml) single-pill combination (SPC) in hypertensive patients with different stroke subtypes (hemorrhagic, ischemic, or mixed).China Status II was a multicenter, postmarketing, prospective observational study in hypertensive patients uncontrolled on monotherapy.

The structures of all compounds were identified by ¹H-NMR, HR-MS and IR spectra, in which compounds 6a-h were further identified by C-NMR spectra. The in vitro antitumor activity of the synthesized compounds was tested by MTT assay.

This sensing system is composed of three probes, one capturing probe (CP) and one assistant probe (AP) which are co-immobilized on the Au electrode surface, and one 3-methylene blue (MB) modified signaling probe (SP) free in the detection solution. One duplex are formed between AP and SP with the target, a specific HBV gene sequence, hybridizing with CP.

However, various severe complications are also reported during the TLE such as cervical anastomotic leakage, chylothorax, and tracheal injury. The aim of this study was to introduce a new optimized TLE procedure for the esophageal cancer and assess its safety and clinical effects.

Objective: To observe the characteristics of serum protein in patients with benign paroxysmal positional vertigo (BPPV) during the symptomatic period.
Method: Fifty-five patients with BPPV and 58 control subjects were enrolled in the study. All the patients underwent the Dixe-Hallpike and Roll maneuver to confirm the type of BPPV.
With the help of the interaction mode of capture probe-target-signal probe (CP-T-SP), an electrochemical sensing method based on the synergism strategy of dual-hybridized signaling probes modified with 6 MB (methylene blue), background suppression and large surface area Au electrode is developed for the detection of Streptococcus pneumoniae (S. pneumoniae) Lyt-1 gene sequence. The proposed sensor features a very low detection limit (LOD) of ∼0.

The antitumor activities of these molecules were evaluated on five cancer cell lines. The results of in vitro assay against human hepatocellular carcinoma cell lines (SK-HEP-1 and HepG2 and SMMC-7721 cells), acute promyelocytic leukemia NB4 cells and uterine cervix cancer HeLa cells, show several compounds to be endowed with cytotoxicity in micromolar to submicromolar range.

Our previous study suggested that erythropoietin (Epo) pre-treatment suppressed hippocampal neuronal death in rats after 1 h of SE convulsions. However, the underlying protective mechanism remained unclear.
