Background: Ultrasound-guided intercostal nerve block (UINB) and thoracoscopic-guided intercostal nerve block (TINB) are often used for analgesia after thoracic surgery. Herein, we compared the application of TINB and UINB for analgesia after uniportal video-assisted lobectomy.
Methods: Sixty patients were randomly allocated into two groups: UINB and TINB.
Background: Thoracoscopic-guided thoracic paravertebral nerve block (TG-TPVB) and thoracoscopic-guided intercostal nerve block (TG-INB) are two postoperative analgesia technology for thoracic surgery. This study aims to compared the analgesic effect of TG-TPVB and TG-INB after uniportal video-asssited thoracic surgery (UniVATS).
Methods: Fifty-eight patients were randomly allocated to the TG-TPVB group and the TG-INB group.
Introduction: Ultrasound-guided thoracic paravertebral block (UTPB) is widely used for postoperative analgesia in thoracic surgery. However, it has many disadvantages. Thoracoscopy-guided thoracic paravertebral block (TTPB) is a new technique for thoracic paravertebral block (TPB).

Non-structural carbohydrates (NSC) are essential substances for the tree growth and metabolism, and play an important role in environmental adaptation of trees. At temporal scale, NSC contents in trees have limited inter-annual variation, which could be attributed to the strategy of tree growth and carbon storage. Different factors influence NSC contents of trees in various climatic regions, which change substantially at the seasonal scale.

Tree seedlings are one of the important components in alpine treeline ecotone, whose regeneration is crucial to treeline migration in response to climate change. We analyzed the spatial distribution, regeneration of tree seedlings and their responses to climate change in treeline ecotone in recent decades. The spatial distribution of tree seedlings in treeline ecotone is dominated by diffuse and clustered forms, with different indicative significance for spatial dynamics of treeline.

The results showed that the diurnal variation of ψ of S. littoreus mainly demonstrated a 'W' curve pattern, with a temporary rise at midday.

The results showed that the nebkhas had the highest surface shear strength (0.
