Laparoscopic anterior hepatic transection for resecting lesions originating in the paracaval portion of the caudate lobe (with videos).

Background: The paracaval portion of the caudate lobe is located in the core of the liver. Lesions originating in the paracaval portion often cling to or even invade major hepatic vascular structures. The traditional open anterior hepatic transection approach has been adopted to treat paracaval-originating lesions.

Laparoscopic middle-hepatic-vein-guided anatomical hemihepatectomy in the treatment of hepatolithiasis: a 10-year case study.

Background: This retrospective 10-year case study evaluated the perioperative results and long-term efficacy of laparoscopic middle-hepatic-vein-guided hemihepatectomy (L-MHV-H) and traditional anatomical hemihepatectomy (TAH) in the treatment of hepatolithiasis (HL).

Methods: From January 2010 to December 2019, 99 patients with regional HL underwent laparoscopic anatomical hemihepatectomy (LAH) at our centre, including 43 patients in the L-MHV-H group and 56 patients in the TAH group.

Results: All patients in both groups were Child-Pugh grade A before operation.

Cranial-Dorsal Approach Along the Middle Hepatic Vein Facilitating Laparoscopic Left Hemihepatectomy.

The exposure and protection of middle hepatic vein (MHV) is crucial and difficult for anatomic laparoscopic left hemihepatectomy in the treatment of left hepatic tumor. 1, 2 The traditional caudal approach, which the liver is transected from the branch to the main trunk of MHV, is prone to damage the vessels. 3, 4 The ventral approach is easy to expose the main trunk of MHV; however, the risk of vascular laceration caused by the caudal approach cannot be completely avoided, since the direction of endoscopic view and liver dissection are from the foot to the head side.

Comparative evaluation of peptidome and microbiota in different types of saliva samples.

Background: Clinical and research interest in salivary peptidome and microbiota is ever-growing owing to its great value for diagnosis, risk assessment and prediction of prognosis in oral and systemic diseases. Saliva can be stimulated for the purpose of rapid collection, but currently there are no studies systematically addressing the similarities and differences of salivary peptidome and microbiota in different types of samples. The purpose of this study was to investigate the variations of salivary peptidome and microbial profiles in response to different stimulating conditions.

Hypoxia induces actin cytoskeleton remodeling by regulating the binding of CAPZA1 to F-actin via PIP2 to drive EMT in hepatocellular carcinoma.

Studies have shown that hypoxia can induce cytoskeletal injury and remodeling through the activation of the RhoA/ROCK signaling pathway by hypoxia-inducible factor-1α (HIF-1α). Our previous study confirmed that CAPZA1 can modulate EMT by regulating actin cytoskeleton remodeling. However, the relationship between HIF-1α and CAPZA1 has not been illustrated.
