Chinese Medical Equipment Journal 2004;0(08):-
The clinical features of the emergent and seriously ill patients are summarized,the mechanisms,features and fields of applications of current commonly-used emergency transporting ventilators are studied and analyzed,the advantages and disadvantages of various types of emergency transporting ventilators in the clinical application of emergency transporting are made comparisons. The technical development of domestic and foreign emergency transport ventilators is introduced,which points out that mini and multi-functional ventilators are the inevitable trend of emergency transporting ventilators and should be used in correspondence with specific clinical circumstances.

To understand the relationship of neurotransmitter between the striatum and limbic system such as amygdaloid nucle-us and bed nucleus of the stria terminalis. 30 male Sprague Dawley rats were used. Immunohistochemical ABC method was per-formed to detect the expression of substance P (SP), calcitonin gene-related peptide (CGRP), leucine-enkephalin (L-enk),cholecyctokinin (CCK) and neuronal nitric oxide synthase (NOS) on seetions of the brain. Some transmitters including substanceP, calcitonin gene-related peptide and cholecyctokinin were mainly distributed at the marginal division of the striatum. Theleucine-enkephalin was mainly distributed at the globus pallidus and was secondly distributed at the marginal division of the stria-tun. The neuronal nitric oxide synthase was mainly distributed at caudate putamen and the marginal division. All these transmit-ters were not only distributed at amygdaloid nucleus and bed nucleus of the stria terminalis, but also had fibers connection amongthe amygdaloid nucleus, marginal division and bed nucleus of the stria terminalis. CONCLUSION: There were special fibersconnection between the marginal division and other basal ganglia nucleus or the limbic system. The marginal division may beplayed some important functions of basal ganglia and limbic system.

Objective:To investigate the clinical outcome of extended Carlson approach to plate fixation of tibial plateau fracture with combined posterolateral and anterolateral fragments.Methods:A retrospective case series study was made on 16 patients with tibial plateau fracture with combined posterolateral and anterolateral fragments admitted to First Affiliated Hospital of Fujian Medical University from January 2015 to September 2019. There were 10 males and 6 females, with age of (35.2±4.3)years (range, 22-59 years). According to the Schatzker fracture classification, type II was found in 10 patients, type III in 4, type V in 1 and type VI in 1. Two-column fractures were found in 14 patients and three-column fracture in 2 patients. All patients were treated by plate fixation through the extended Carlson approach. The anterior-posterior X-ray and 3D reconstruction CT scan test were taken at every 3 months after operation to assess fracture healing and posterior tilt angle of lateral tibial plateau. The Rasmussen knee function score was performed 12 months after operation. Complications were detected as well.Results:All patients were followed up for 13-38 months [(18.3±4.6)months]. All patients showed bone healing. At postoperative 12 months, the posterior tilt angle of lateral tibial plateau was reduced to (11.5±4.7)°, compared to preoperative (28.9±3.2)° ( P<0.05). At postoperative 12 months, the Rasmussen score was (25.8±1.1)points compared with preoperative (13.1±3.8)points ( P<0.05), and the results were excellent in 9 patients (56%), good in 6 (37%), and fair in 1 (6%), with the excellent-good rate of 94%. No complications were observed, such as skin necrosis, surgical site infection, internal fixator exposure or osteomyelitis. Conclusion:For tibial plateau fracture with combined posterolateral and anterolateral fragments, plate fixation via the extended Carlson approach is effective to reduce and fix the fracture, decrease the posterior tilt angle of lateral tibial plateau and improve the recovery of postoperative knee function, with no neurovascular injury complications.

[Abstract] Objective: To investigate the molecular mechanism of miR-143-3p regulating the proliferation, migration and invasion of colon cancer RKO cells via targeting enhancer of zeste homolog 2 (EZH2). Methods: A total of 40 pairs of colon cancer tissues and corresponding para-cancerous tissues resected in the First Affiliated Hospital of Kunming Medical University from March 2015 to July 2017 were collected for this study. In addition, colon cancer cell lines (COLO320, RKO and CL-11) and normal intestinal mucosa NCM460 cells were also collected. qPCR was applied to detect the expression level of miR-143-3p in colon cancer tissues and cell lines. miR-143-3p mimics, miR-143-3p inhibitor, EZH2 siRNA and negative control plasmids were transfected into RKO cells,
respectively. The effect of miR-143-3p/EZH2 axis on the proliferation, migration and invasion of RKO cells were detected by CCK-8 and Transwell assay, respectively. Western blotting was used to detect the expression level of EZH2 protein in RKO cells. The targeting relationship between miR-143-3p and EZH2 was verified by Dual luciferase reporter gene assay. Results: The expression level of miR-143-3p was downregulated in colon cancer tissues and cell lines (all P<0.01). Overexpression of miR-143-3p significantly inhibited the proliferation, migration and invasion of RKO cells (all P<0.01). Dual luciferase reporter gene assay confirmed that EZH2 was a target gene of miR-143-3p. Simultaneous knockdown of miR-143-3p and EZH2 attenuated the inhibition of EZH2 knockdown on the proliferation, migration and invasion of RKO cells. Conclusion: miR-143-3p suppresses the proliferation, migration and invasion of colon cancer cells via targetedly down-regulating EZH2.
