The new era imposes heightened demands on medical professionals,who must not only possess a solid theoretical foundation but also exhibit strong practical skills and innovative capabilities.The quality of medical func-tional laboratory construction is crucial for cultivating high-caliber medical talents.In light of the current developmental status and trends regarding functional experiment teaching within Chinese higher education institutions,particularly the disparities in development across various regions and institutions,the Functional Experiment Teaching Committee of the Chinese Pathophysiology Society has developed an expert consensus on laboratory construction standards.This consensus was established through comprehensive investigations,research,and extensive discussions to provide a reference for di-verse institutions to continuously enhance their levels of laboratory construction.

The occurrence and development of solid tumors rely on the autonomous drive of tumor cells and the crosstalk of the tumor microenvironment (TME). As a crucial component of the TME, cancer-associated fibroblasts (CAFs) are the center of the cross-communication among various cells in the tumor stroma and participate in tumorigenesis, progression, invasion, and migration. Hence, targeting CAF subpopulations or their functional pathways might offer a new breakthrough for tumor prevention and treatment. However, the concurrent tumor-promoting and tumor-suppressive functions of CAFs pose an impediment to this breakthrough. By summarizing CAFs role in tumor occurrence and progression, this review proposes the application of CAFs in tumor prevention and treatment and discusses their potential and value as a therapeutic target.

ERK1/2 is a key protein that mediates cell signal transduction,and it is involved in regulating biological processes such as chromatin remodeling,nuclear disintegration,proliferation,survival,metabolism,and cell migration and differentiation.Its overactivation is closely related to the occurrence and progression of cancer,and the mechanism is manifested as the overactivation of ERK1/2 by gene mutations of upstream pathway molecules or regulators and the reactivation of ERK1/2 after inhibition against the above targets.ERK1/2 is a potentially valuable target.In this review,the mechanism of post-translational modification and spatial regulation of ERK1/2 and the application status of corresponding small-molecule inhibitors were discussed.The current antitumor strategy of targeting and regulating ERK1/2 was summarized,and the possibility of exploring potential targets was elucidated,thus providing new insights into the developmental research of ERK1/2 as an ideal anticancer target.

Objective To compare different drainage methods after right hepatectomy. Methods From April 2017 to February 2018, 90 patients who underwent right hepatectomy at Zhongshan Hospital of Fudan University were prospectively randomized to the latex tube group (right subphrenic drain with a latex tube connecting to a collection bag, n=30), the silicone tube group (right subphrenic drain with a silicone tube connecting to a closed-suction, n=30) or the combination group ( right subphrenic drain with a latex tub, combined with a silicone tube, n=30). The amount of fluid collection after the operation, complications after surgery, recovery of liver function, and length of hospital stay after operation were compared. Results There were no significant differences in the clinicopathological features among the 3 groups, including gender, age, cirrhosis status, extent of hepatectomy, and blood loss (P＞0. 05). There were no significant differences among the three groups on the incidences of postoperative complications [ the latex tube group, 20. 0% (6/30); the silicone tube group, 23. 3% (7/30); the combination group, 16. 7% (5/30); P＞0. 05]. Ultrasonography showed significantly lower rates of subphrenic collection in the combination group compared with the latex tube group and the silicone tube group [16. 7% (5/30) vs. 63. 3% (19/30) vs. 53. 3% (16/30); P＜0. 05]. The rates of postoperative fever, serum total bilirubin, ALT and postoperative hospital stay were similar among the three groups (P＞0. 05). Conclusions Drainage using the combina-tion of a latex tube connecting to a collection bag and a silicone tube connecting to closed-suction after right hepatectomy significantly reduced postoperatively subphrenic collection and prevented infection of the collec-tion. However, the treatment strategy did not delay liver function recovery, prolong hospital stay nor increase post-operative infection rate.

Objective To investigate the effect of long non-coding RNA (LncRNA) Hox transcript antisense inter-genic RNA ( HOTAIR ) on the cell proliferation and apoptosis of renal cancer cell lines 786-O and ACHN. Methods Small interfere RNA ( siRNA ) that aims to down-regulate HOTAIR expression was transfected into two renal cell lines respectively, and the transfection efficiency was evaluated by qRT-PCR. Then the MTT assay,Ho-chest staining assay and enzyme-linked immunosorbnent assay(ELISA) were used to detect cell proliferation and apoptosis. Results The expression of HOTAIR could be down-regulated effectively by the siRNA (P < 0. 05). Down-regulation of HOTAIR could inhibit the proliferation(P < 0. 05) and increase apoptosis(P < 0. 05) of two re-nal cancer cells. Conclusion HOTAIR plays a role in promoting cell growth of renal cancer.
