Background: Pneumonia is one of the most common complications after lung resection. However, there are currently no reports of postoperative pneumonia in patients with bronchiectasis.
Objectives: Our study aims to construct a new nomogram to predict the risk of postoperative pneumonia in patients with localized bronchiectasis.
Hydrogen sulfide (HS) is a crucial signaling molecule in plants. Recent studies have shown that HS plays an equally important role as nitric oxide (NO) and hydrogen peroxide (HO) in plant signaling. Previous studies have demonstrated the involvement of HS in regulating drought and other stressful environmental conditions, but the exact downstream molecular mechanisms activated by the HS signaling molecule remain unclear.

Six novel buckwheat (Duoku, Dk) were generated by crossing of Golden buckwheat and Tatary buckwheat, and their kernel appearance properties and starch physicochemical properties were analyzed together with one domestic line (Cimiqiao) and one wild line (Yeku). The results showed that Dk samples had better appearance properties than two control samples.

Protease serine 3 (PRSS3), possessing four splice variants (; -), is an indispensable trypsin that shows paradoxical effects on cancer development. Here, we found that transcripts and their isoforms were divergently expressed in lung cancer, exhibiting opposing functions and clinical outcomes, namely, oncogenic PRSS3-V1 and PRSS3-V2 tumor-suppressive PRSS3-V3, by targeting different downstream genes.

However, whether patients who underwent subsegmentectomy could obtain satisfactory clinical outcomes remains unclear. The present study aimed to compare the clinical outcomes and security of surgical procedures between subsegmentectomy and segmentectomy.

The prognostic influent factors and therapeutic methods of PSCC are unclear, for there are only some case reports or small samples' analysis. This study aims to find prognosis related factors of PSCC, develop and validate a nomogram to predict their survival probability.

Patient And Methods: Sixty-three NSCLC patients from Beijing Chest Hospital were included.
Background: Although a well-acknowledged component of curative surgery for lung cancer, investigators have recently questioned the need for mediastinal lymph node dissection (MLND) in early-stage lung cancer cases. As such, the accurate prediction of N2 stage prior to surgery has become increasingly critical. But diagnostic biomarkers predicting N2 metastases are deficient, which are urgently needed.

Background: Immunotherapy represented by immune checkpoint inhibitors (ICIs) has become the standard treatment for patients with non-oncogenic advanced non-small cell lung cancer (NSCLC). While lung cancer is most prevalent in elderly patients, these patients are rarely included in pivotal clinical trial studies. We aimed to describe the efficacy and safety of immunotherapy for elderly patients in the "real-world".

Vein-first ligation substantially reduces CTC dissemination and achieves favorable survival compared with artery-first ligation. In this study, we further explored whether the timing of pulmonary vein (PV) ligation determined according to the early and late PV ligation technique is associated with CTC dissemination.

Hydrogen sulfide (HS) and melatonin (MEL) reportedly have similar functions in many aspects of plant growth, development and stress response. They regulate stomatal movement and enhance drought resistance.

We aimed to assess retrospectively the antitumour activity and safety of neoadjuvant chemoimmunotherapy for resectable stage Ib-IIIb NSCLC.
Methods: Twenty patients who had been diagnosed as stage Ib-IIIb NSCLC and received chemoimmunotherapy as neoadjuvant treatment between November 2019 and December 2020, in Beijing Chest Hospital, Capital Medical University were recruited.
Purpose: Accumulating evidence has indicated that dysregulated microRNAs (miRNAs) are involved in cancer progression. In this study, we evaluated the clinicopathologic significance of miR-183-3p and miR-182-5p, and the role of miR-183-3p in non-small-cell lung cancer (NSCLC) progression.
Patients And Methods: Seventy-six NSCLC patients from Beijing Chest Hospital were included.

Our previous study on the genic male sterile-fertile line 114AB of Capsicum annuum indicated a diversity of differentially expressed cDNA fragments in fertile and sterile lines. In this study, a transcript-derived fragment (TDF), male fertile 4 (CaMF4) was chosen for further investigation to observe that this specific fragment accumulates in the flower buds of the fertile line. The full genomic DNA sequence of CaMF4 was 894 bp in length, containing two exons and one intron, and the complete coding sequence encoded a putative 11.

In this work, we examined the accumulation of one of the transcript-derived fragments (TDFs), CaMF3 (male fertile 3), in the flower buds of a fertile line. The full genomic DNA sequence of CaMF3 was 1,951 bp long and contained 6 exons and 5 introns, with the complete sequence encoding a putative 25.

A transcript-derived fragment (TDF) specifically accumulated in the flower buds of fertile line was isolated, and the corresponding full-length cDNA and DNA were subsequently amplified.
