    Objective: The current study aims to identify the effects of exogenous application of pulsed electromagnetic fields on skin wound healing in diabetic rats, and thus provides experimental evidence for its more scientific clinical application in the future. Methods: The diabetic animal models were established via intraperitoneal injection of streptozotocin in 4-monthold male rats. Fourth eight rats were randomly assigned into the diabetes group (DM) and diabetes coupled with pulsed electromagnetic fields (DM+PEMF) group. Another 24 normal rats were used as the blank control group (Control). Then, all the rats in the three groups were subjected to dorsal surgery for the establishment of soft tissue wound model (circular wound with the diameter of 2 cm). Then, the rats in the DM+PEMF group were subjected to pulsed electromagnetic fields stimulation. Then, 6 rats in each group were sacrificed at Day 5, 12 and 19 post surgery. The glucose levels, wound closure, wound healing time and tissue tensile strength were examined and analyzed. Results: Pulsed electromagnetic fields significantly increased the wound closure rate in diabetic rats at Day 5, 12 and 19 post surgery, decreased overall wound healing period in diabetic rats, and also enhanced tissue tensile strength in diabetic rats at Day 5, 12 and 19 post surgery. Conclusion: Low-intensity pulsed electromagnetic fields can significantly accelerate diabetic wound healing process, and also improve diabetic tissue repair capacity. This study may be helpful for providing more scientific and reasonable experimental evidence for the treatment of pulsed electromagnetic fields on diabetic wound healing in clinics.

    摘要:
    Cervical laminoplasty surgery is an alternative to laminectomy. It can increase the space of the spinal cord available by raising the lamina, and achieve the indirect decompression effect to treat cervical spondylosis. Various techniques of laminoplasty have since been developed after two prototype techniques: Hirabayashi’s open-door laminoplasty and Kurokawa’s double-door laminoplasty. Several studies report superior biomechanical stability of the cervical spine after laminoplasty compared with laminectomy. Recent development in laminoplasty is preservation of muscle attachment, which enabled dynamic and static stabilization of the cervical spine by neck extensor muscles. After treatment with new laminoplasty techniques with active postoperative neck muscle exercises, postoperative instability, kyphosis, axial neck pain, and loss of ROM become minimal. The development,complications and future trends of cervical laminoplasty are summarized below.

    Objective: To investigate the correlation between the change in expression of the tumor associated macrophage (TAM) markers CD68 and CD206 and the clinicopathological parameters. Methods: We retrospectively analyzed 28 PGI-DLBCL patients by immunohistochemical stainning. The surface expression of biomarkers CD68 and CD206 on TAMs in samples obtained at diagnosis was compared with that in specimens obtained at first relapse. Based on the change in expression levels of CD68 and CD206 from diagnosis to relapse, patients were categorized into three groups: “increased”, “stable” and “decreased”. Results: A significant difference was observed between the three groups with respect to CD68 and CD206 expressions (P=0.012) and there existed a consistency between the two (P=0.008). The three groups showed a negative correlation with age, sex, stage, B symptoms, diagnosis, ECOG performance status, and IPI scores, while a positive correlation was observed with the site of lesion of CD206 expression (P=0.032). The time to relapse (TTR) in the three groups of CD68 and CD206 was not significantly different (P=0.23, P=0.818). Conclusion: Our study suggests that increase in CD206 and decrease in CD68 expression at relapse indicates M1-TAM polarization into M2-TAM, which plays an important role in PGI-DLBCL relapse. Furthermore, M2-TAM polarization may be associated with the site of Primary gastric diffuse large B lymphoma.

    Objective: To systematically evaluate the effects of sleep status on renal function in patients with chronic kidney disease (CKD). Methods: To search the relevant literature related to the effects of sleep status on renal function of CKD patients on PubMed database, EMBase database, the Cochrane Library database, CNKI database, Chinese Biomedical Literature Database, VIP and Wanfang database from the initial to June 2018, all literature that met the criteria were included. According to the type of studies, the quality of the literature was evaluated by NOS scale in the cohort study and AHRQ scale in the cross-sectional study, and systematically evaluated the outcome indicators, the main outcome indicators were estimated glomerular filtration rate (eGFR) and endogenous creatinine clearance rate (Ccr), while the secondary indicators were Pittsburgh Sleep Quality Index (PSQI), Sleep Quality (SQ), Serum Creatinine (Scr), Hemoglobin (Hb), Albumin (ALB) and Urine Protein/Creatinine Ratio (UPCR). Results: Four literature and one meeting abstract were included in this study, of which four were cohort studies, three of them the NOS quality evaluations were high, one of them was medium, the remaining one was cross-sectional study, and the AHRQ quality evaluation was medium. This study shows that sleep status has a certain correlation with renal function. Shorter sleep time or poor sleep quality can lead to deterioration of renal function. Among them, the research data of Sabbatinit research team in Italy showed that Ccr gradually decreased with the increased of the PSQI; studies of Cohen research team and the Ricardo research team in the United States showed that eGFR decreased with the increased of the PSQI; the study of Kumar research team in the United States showed that the lower SQ , the worse renal function; the study of Knutson’ research team in British showed that the shorter sleep time, the lower eGFR. In addition, studies showed that sleep index also has influence on Hb, ALB, Scr, UPCR and other indicators. Conclusion: Sleep status can affect the renal function of CKD patients in different degrees. Shorter sleep time and poor sleep quality will damage renal function and accelerate the progress of CKD.

    Objective: Investigating the anti-inflammatory effects of magnolol on lipopolysaccharide (LPS)-induced inflammation model mouse and its effect on NF-κB pathway. Methods: Mice were randomly divided into 5 group: normal control group, inflammatory model group, dexamethasone positive drug group and, magnolol group. After administrating for 7 d, LPS was intraperitoneally injected to induce inflammatory on the 8th day, and blood was taken 3 h later and the thymus and spleen were weighed. The levels of serum TNF-α, IL-22 and IL- 17 were detected by ELISA method. The expression levels of TNF-α, NF-κB p65 and IL- 17 in thymus were detected by immunohistochemistry. Results: Magnolol could evidently reduce the levels of serum TNF-α, NF-κB p65 and IL-17 and IL-22. Immunohistochemistry result showed that magnolol could down-regulate the expression of IL-17, TNF-α and p65. Conclusion: Magnolol can prevent and treat LPS-induced inflammation. Its anti-inflammatory effect is connected with the down-regulation of TNF-α and NF-κB p65 protein levels by IL- 17 inflammatory pathway. This experiment provides a theoretical basis for magnolol in antiinflammatory.

    目的:探讨鹰嘴豆芽素A对宫颈癌细胞增殖及迁移能力的调控作用及其可能的分子机制。方法:体外培养Hela细胞,以不同质量浓度的鹰嘴豆芽素A处理宫颈癌Hela细胞,CCK-8法检测鹰嘴豆芽素A对宫颈癌细胞的增殖影响;划痕实验检测对细胞迁移的影响;RT-PCR法检测鹰嘴豆芽素A对Bcl-2 /Bax mRNA水平表达的变化。结果:鹰嘴豆芽素A能够抑制Hela细胞的增殖和迁移,呈现剂量和时间依赖性(P<0.05);质量浓度为10、20、40、80、160 μmol/L鹰嘴豆芽素A处理Hela细胞24 h、48 h后,抑制Hela细胞增殖和迁移速率明显上升,并且高于对照组(P<0.05);促凋亡蛋白Bax表达水平升高,抗凋亡蛋白Bcl-2表达水平降低,呈剂量依赖性。结论:鹰嘴豆芽素A能够抑制宫颈癌Hela细胞的增殖和迁移,其作用机制可能与下调Bcl-2,上调Bax有关。
