Actinomycins are known for their anti-tumor, antibacterial and antiviral activities, and in particular for the ability of actinomycin D as a clinical drug to treat a variety of cancers. In our ongoing work to obtain novel natural products from endophytic actinomycetes derived from traditional Chinese herbs, we identified the potential to produce actinomycins in YINM00002, a strain derived from . According to genome mining, we isolated actinomycins D and V (1 and 2) and small amounts of 4-methyl-3-hydroxyanthranilic acid (4-MHA) derivates (3 and 4) from strain fermentation broth.

Percutaneous nephrolithotomy is generally performed under general or regional anesthesia; however, it is rarely performed under local infiltration anesthesia (LIA). This study aimed to assess the safety and effectiveness of Chinese mini percutaneous nephrolithotomy (MPCNL) for upper urinary calculi under LIA. A retrospective analysis of 52 patients with upper urinary stones who underwent MPCNL under LIA from April 2019 to May 2022 was performed.

Five previously undescribed epoxy octa-hydronaphthalene polyketides, altereporenes A-E (1-5) were isolated from rice culture of the endophytic fungus sp. YUD20002 derived from the tubers of . Their structures were determined on the basis of comprehensive spectroscopic analyses, while the absolute configurations were elucidated by the comparison of experimental and calculated specific rotations.

Ten undescribed C polyketide phialocetones A-J, featuring twelve-, six- and five-membered lactone moieties, were isolated from a rhizospheric soil-derived Phialocephala sp. YUD18001 associated with Gastrodia elata. Their structures were established by NMR spectroscopic analysis and HRMS, while their absolute configurations were determined by computational methods and chemical reactions.

A talented endophytic bacteria strain YINM00001, which showed strong antimicrobial activity and multiple antibiotic resistances, was isolated from a Chinese medicinal herb Miq. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain was closely related to NRRL B-2000T (99.93%).

Background: Uniportal video-assisted thoracoscopic surgery (U-VATS) can achieve traditional clinical outcomes comparable to those of multiportal video-assisted thoracoscopic surgery (M-VATS). This study aimed to compare patient-reported outcomes between U-VATS and M-VATS for lung cancer lobectomy in the early postoperative period.

Methods: This comparative analysis used data from a longitudinal prospective study (Perioperative Symptom Study of Lung Cancer [CN-PRO-Lung 1]).

A hydroxyl-functionalized homochiral porous organic cage (POC) was synthesized and characterized by FTIR, NMR, thermogravimetric analysis (TGA), MALDI-TOF-MS, and elemental analysis. The synthesized homochiral POC was used as stationary phase to prepare a capillary gas chromatography (GC) column by a static coating method. The fabricated column shows excellent selectivity not only for the separation of positional isomers but also for the resolution of various racemates.

Background: To introduce a modified pleurodesis as an effective treatment for refractory chylothorax and to develop a novel insight for its mechanism.

Methods: Patients who underwent thoracic surgery at West China Hospital or its affiliated hospitals between 2010 and 2015 and who subsequently experienced chylothorax that was not resolved by conventional treatment, received daily pleurodesis involving 100 mL 50% glucose and 20 mL 1% lidocaine. The chest tube was clamped after 7 days of pleurodesis, regardless of drainage amount.

Background: Postoperative hemorrhage after lung cancer surgery is a potentially fatal complication. This study aimed to investigate the indications and timing of reoperation for postoperative hemorrhage after lung cancer surgery.

Methods: We identified all patients who underwent lung resection and mediastinal lymph node dissection for lung cancer between October 2001 and September 2015 at Sichuan Cancer Hospital, identifying 57 who had undergone reoperation for hemostasis.

We used a reverse-puncture anastomotic technique in a total minimally invasive Ivor-Lewis esophagectomy. In the operation, a needle with a wire passed through the puncture head of the anvil of a circular stapler was used to make a fixed knot. In the proximal esophagus, the tissue was hemitransected, and the anvil was then inserted into the esophagus.

Urethral stricture is a common urologic disease and there are many therapeutic methods for it. Here we investigated the application of balloon dilation under B-mold ultrasound monitoring in the treatment of urethral stricture. Five male patients suffering from urethral stricture were treated with balloon dilation under B-mold ultrasound monitoring.

The relationship between sexual reproduction and clonal growth in clonal plants often shows up at the ramet level. However, only a few studies focus on the relationship at the genet level, which could finally account for evolution. The sexual reproduction and clonal growth of Ligularia virgaurea, a perennial herb widely distributed in the alpine grasslands of the Qinghai-Tibetan Plateau of China, were studied under different competition intensities and light conditions at the genet level through a potted experiment.

Background: The purpose of the present study was twofold: to summarize the characteristics of trauma patients with thoracic injury in the 2008 earthquake of Wenchuan, Sichuan, China, and to validate the accuracy of the Injury Severity Score (ISS), the New Injury Severity Score (NISS), and the Chest Injury Index (CII) in prediction of respiratory failure.

Methods: A group of 1,823 patients injured in the earthquake of Wenchuan were transferred to West China Hospital, Sichuan University, between May 12 and May 27, 2008. Of these 1,823 patients, 184 (10.
