ABSTRACT

ObjectiveTo investigate the protective effect of total lignans of Arctii Fructus on the retinal tissue in the rat model of type 2 diabetes mellitus. MethodWistar rats were randomized into normal, model, solvent, Shuangdan Mingmu Capsules (618 mg·kg-1), and low-, medium-, and high-dose (100, 200, 400 mg·kg-1, respectively) total lignans of Arctii Fructus groups, with 16 rats in each group. The rat model was established by streptozotocin (STZ) combined with a high-fat diet and administrated with corresponding drugs by gavage once a day for 14 weeks. At the 14th week, blood was sampled for the collection of serum from the abdominal aorta after anesthesia, and bilateral eyeballs were collected and frozen. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of the retinal tissue in rats. The pathological changes of retinal vascular network in rats were observed by retinal vascular tissue digestion and mounting The levels of vascular endothelial growth factor (VEGF), tumor necrosis factor-α (TNF-α), and intercellular adhesion molecule-1 (ICAM-1) in the serum were determined by the ELISA kit. ResultCompared with the normal group, the solvent group showed pathological changes in the retinal tissue, reduced retinal ganglion cells (P<0.01), and retinal thinning (P<0.01), decreased E/P value in retinal blood vessels (P<0.01), and elevated serum levels of VEGF, TNF-α, and ICAM-1 (P<0.01). Compared with the model group, the total lignans of Arctii Fructus increased the retinal ganglion cells (P<0.01), thickened the retina (P<0.01), and lowered the serum levels of VEGF, TNF-α, and ICAM-1 (P<0.05, P<0.01). ConclusionTotal lignans of Arctii Fructus may lower the VEGF, TNF-α, and ICAM-1 levels to protect the retina.

ABSTRACT

Osteoarthritis is a prevalent global joint disease, which is characterized by inflammatory reaction and cartilage degradation. Cyasterone, a sterone derived from the roots of Cyathula officinalis Kuan, exerts protective effect against several inflammation-related diseases. However, its effect on osteoarthritis remains unclear. The current study was designed to investigate the potential anti-osteoarthritis activity of cyasterone. Primary chondrocytes isolated from rats induced by interleukin (IL)-1β and a rat model stimulated by monosodium iodoacetate (MIA) were used for in vitro and in vivo experiments, respectively. The results of in vitro experiments showed that cyasterone apparently counteracted chondrocyte apoptosis, increased the expression of collagen II and aggrecan, and restrained the production of the inflammatory factors inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), a disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMTS-5), metalloproteinase-3 (MMP-3), and metalloproteinase-13 (MMP-13) induced by IL-1β in chondrocytes. Furthermore, cyasterone ameliorated the inflammation and degenerative progression of osteoarthritis potentially by regulating the nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) pathways. For in vivo experiments, cyasterone significantly alleviated the inflammatory response and cartilage destruction of rats induced by monosodium iodoacetate, where dexamethasone was used as the positive control. Overall, this study laid a theoretical foundation for developing cyasterone as an effective agent for the alleviation of osteoarthritis.

ABSTRACT

SUMMARY OBJECTIVE: Heat shock protein A2 has been reported to be tightly associated with tumorigenesis and tumor progression. This study aimed to determine the oncogenic and immunological roles of Heat shock protein A2 in pancreatic cancer by bioinformatics. METHODS: Expression of Heat shock protein A2 in tumorous and normal specimens of pancreatic cancer was analyzed using the Cancer Genome Atlas and the Cancer Genome Atlas + Genotype-Tissue Expression data sets, respectively. Relationships of Heat shock protein A2 expression with immune infiltrates in pancreatic cancer were assessed. Heat shock protein A2-associated coexpressed genes in pancreatic cancer were obtained, followed by the implementation of enrichment analysis. RESULTS: The data demonstrated that Heat shock protein A2 was significantly overexpressed in tumorous samples compared with normal samples. Heat shock protein A2 expression was remarkably positively interrelated with CD8+ T cell, neutrophil, dendritic cell, and macrophage, but not with CD4+ T and B cells. Heat shock protein A2 expression was markedly positively relevant to both cancer-associated fibroblast and endothelial cell. Enrichment data revealed that Heat shock protein A2 was intimately involved in the tumorigenesis and progression of pancreatic cancer. CONCLUSION: Heat shock protein A2 is upregulated in pancreatic cancer and is closely associated with tumor immunity and aggressive progression.

ABSTRACT

Developmental dysplasia of the hip (DDH) is a major cause of hip arthritis and ultimately total hip arthroplasty. Due to the dysplastic acetabulum, how to place the acetabular cup becomes a challenge in acetabular reconstruction for such patients. Especially in the acetabula classified as Crowe typeⅡand type Ⅲ, the dislocation of the femoral head causes bone defects above the true acetabulum, which will affect the stability of the acetabular cup when the acetabular reconstruction is performed at the true acetabulum. Many acetabular reconstruction methods such as bone grafting, the use of small acetabular cups, socket medialization technique, and high hip center technique are used to increase the host bone coverage of the cup. However, each method has its own shortcomings that can not be ignored so that there is no unified conclusion on the acetabular reconstruction methods for Crowe typeⅡand type Ⅲ hip dysplasia. This article summarized and evaluated various reconstruction methods in combination with the acetabular morphology of DDH, and put forward the research direction in the future.

ABSTRACT

BACKGROUND@#Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality.@*METHODS@#A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data.@*RESULTS@#The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P 0.05). The association between negative life events and sleep quality was mediated by negative coping styles.@*CONCLUSIONS@#Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

ABSTRACT

Objective To investigate the anti-inflammatory role of α7 nicotinic acetylcholine receptor (α7nAChR) under inflammatory stress and its mechanisms. Methods PNU282987 was used for the activation of α7nAChR and LPS was administrated as inflammatory stressor. Realtime PCR was used for the detection of IL-1β, IL-6, TNF-α, M1 macrophage marker CD68, CD86 and M2 macrophage marker CD206, Arg1. Cell immunofluorescence was used for the detection of M1/M2 ratio and Western blot was applied for the detection of autophagy-related proteins. Results Under the stimulation of LPS, the mRNA levels of proinflammatory cytokines IL-1β, IL-6 and TNF-α, the proportion of M1 macrophage and autophagy process were increased in BV2 microglial cells. However, the administration of PNU282987 significantly decreased the mRNA levels of IL-1β, IL-6 and TNF-α and the proportion of M1 macrophage while increased the proportion of M2 macrophage and the level of autophagy process. Conclusion Activating α7nAChR plays an anti-inflammatory role in microglial cells under inflammatory stress due to the regulation of M1/M2 macrophage ratio and increase of autophagy level.

ABSTRACT

Objective To investigate the clinical effects of primary revision after artificial hip replacement and causes of revision surgery. Methods A total of 344 patients who underwent revision surgery after total hip arthroplasty (THA) and artificial femoral head replacement from January 2010 to December 2016 were retrospectively analyzed. There were 141 males and 203 fe?males, with a mean age 65.64±10.81 years (28-87 years). A total of 351 hip revisions were performed in 344 patients with 7 pa?tients in bilateral revisions. All patients were followed up for 60.38±22.75 months (24-105 months). All patients with periprosthet?ic infection underwent two?stage revision after prosthesis placement, and all others underwent one?stage revision. The clinical out?comes of revision surgery were assessed with the Harris hip score and the survival rate of the revision prosthesis. According to the duration from artificial hip replacement to revision surgery, all patients were divided into early revision (less than 5 years) and late revision (more than 5 years) groups. They were also divided into two groups according to the age of the patient in revision sur?gery:>55?year?old and≤55?year?old groups. The causes of revision, hip reoperation and re?revision were recorded. Results In the 351 hip revisions, a total of 238 (67.8%) had aseptic loosening, 41 (11.7%) periprosthetic fractures, 30 (8.5%) periprosthetic infection, 23 (6.6%) recurrent dislocation and 19 (5.4%) the eccentric liner wear. The infection rate was significantly higher in the early revision group (21.1%) than that in the late revision group (4.2%) (χ2=24.443, P<0.001). The aseptic loosening rate was sig?nificantly higher in the late revision group (72.4%) than that in the early revision group (54.4%) (χ2=9.899, P=0.002). Sixteen pa?tients underwent hip surgery after revision, including 6 recurrent dislocations, 4 aseptic loosening, 3 periprosthetic fractures, and 3 periprosthetic infections. Eight of them underwent revision surgery, including 4 cases of aseptic loosening, 2 cases of periprosthet? ic fractures, and 2 cases of recurrent dislocation. The duration from the primary revision to the second revision was 22.1 ± 10.0 months (1-75 months). The 5?year and 8?year survival rates of the revision prostheses were 99.3%[95% CI(98.3%, 100.3%)] and 92.6% [95% CI(87.1%, 98.1%)], respectively. The proportions of prosthetic infection and eccentric liner wear in the≤55?year?old group were significantly higher than those in the>55?year?old group (χ2=3.981, P=0.046; χ2=5.226, P=0.022), while the propor?tion of aseptic loosening in the>55?year?old group was significantly higher than that in the ≤55?year?old group (χ2=5.254, P=0.022). The 8?year survival rates of the revision prostheses of ≤55?year?old group and>55?year?old group were 76.8% [95% CI (50.5% , 103.1% )] and 95.4% [95% CI (91.1% , 99.7% )], respectively. Conclusion Young patients have a higher risk of re?revi?sion after revision THA.

ABSTRACT

BACKGROUND:Guided tissue regeneration and bone grafting are a hot spot in the treatment of periodontal bone defect caused by severe periodontitis, but a smal sample size in clinical research wil lead to bias. OBJECTIVE:To systematical y evaluate the effect of guided tissue regeneration combined with bone grafting in the treatment of periodontal bone defect, and explore its feasibility, thus providing evidence for clinical application. METHODS:A computer-based search of PubMed, Cochrane Library, EMbase, CNKI, CqVip and WanFang databases was performed for articles about the guided tissue regeneration and bone graft for periodontal bone defects, published from 2000 to 2016. The keywords were“guided tissue regeneration, bone grafts, periodontal bone defects”in English and Chinese, respectively. The literature selection, data col ection and evaluation of bias were conducted by two researchers independently, and then quality assessment of the included 12 randomized control ed tests was conducted, fol owed by Meta-analysis using Revman 5.3 software. RESULTS AND CONCLUSION:A total of 12 studies were enrol ed, including 414 teeth (228 of which in the experimental group and 216 in the control group). Meta-analysis results showed that compared with the single flap surgery, guided tissue regeneration combined with bone graft could reduce periodontal probing depth by 1.18 mm gingival, make a gingival recession by 0.23 mm, reduce alveolar bone defect depth by 1.57 mm, and increase clinical attachment level by 2.03 mm (P0.05). These results reveal that for moderate to severe chronic periodontitis with periodontal bone defects, guided tissue regeneration combined with bone graft has better clinical effects than simply flap surgery and guided tissue regeneration, but has no significant differences from the bone graft surgery. Herein, we have not yet classified the membrane materials, bone materials and bone substitutes, and there is stil a lack of high-quality and large-sample randomized control ed trials.

ABSTRACT

Objective To study the correlation between microRNA (miRNA) polymorphism and the risk and clinical prognosis of acute radiation esophagitis in patients with esophageal neoplasms. Methods 256 patients with acute radiation esophagitis during radiotherapy were chosen as the experimental group, and 256 patients matched by age and sex without acute radiation esophagitis during radiotherapy were chosen as the control group. The polymorphism types of miRNA-146a (rs2910164) were determined by Taqman gene typing technology of ABI7900HT. The genotype distribution of miRNA-146a rs2910164 polymorphism in the experimental and control groups was analyzed. Logistic regression was performed to estimate the odds ratio (OR) and 95%confidence interval (95%CI ). Results The genotype frequencies of CC, GG and CG at miRNA-146a polymorphic site rs2910164 in the experiment and control group were 20.70 % (53/256) and 33.20 % (85/256), 45.32 % (116/256) and 40.63 % (104/256), 33.98 % (87/256) and 26.17 % (67/256), respectively. There was a statistically significant difference between two groups (all P< 0.05). Compared with gene type CC, the OR values of acute radiation esophagitis in patients with gene type GC and GG were 0.654 and 0.627, respectively (P< 0.05), indicating that they had a low risk. The negative effect rates in patients with gene type GG, CG and CC were 7.69 % (8/104), 19.40 % (13/67) and 41.18 % (35/85), respectively. There was a statistically significant difference in the clinical prognosis among these genotypes (P< 0.05). Conclusion Gene type CC at miRNA-146a polymorphic site rs2910164 can increase the risk of acute radiation esophagitis and decrease the clinical prognosis in patients with esophageal neoplasms.

ABSTRACT

<p><b>PURPOSE</b>To enhance the awareness of rare complications of pelvic fracture and describe the correct diagnosis and effective treatment.</p><p><b>METHODS</b>A total of 188 cases of pelvic fractures were retrospectively reviewed, and four patients who suffered from four types of rare pelvic fracture complications were described, namely ureteral obstruction caused by retroperitoneal hematoma-induced abdominal compartment syndrome (ACS), bowel entrapment, external iliac artery injury, and open scrotal sac injury.</p><p><b>RESULTS</b>We demonstrated that combined measures should be employed to prevent the occurrence of ACS following major pelvic fractures. Ureteral catheter support may be a good option at an early stage when ACS occurred. Contrasted computed tomography examination and sufficient awareness are keys to a correct diagnosis of bowel entrapment following pelvic fractures. Recognition of risk factors, early diagnosis, and prompt treatment of suspected injury of the external iliac artery are keys to patient survival and to avoid limb loss. Scrotal and/or testicular injury complicated by pelvic fractures should be carefully treated to maintain normal gonad function. Additionally, establishment of a sophisticated trauma care system and multi-disciplinary coordination are important for correct diagnosis and treat- ment of rare complications in pelvic fractures.</p><p><b>CONCLUSIONS</b>Rare complications of pelvic fractures are difficult to diagnose and negatively impact outcome. Recognition of risk factors and sufficient awareness are essential for correct diagnosis and prompt treatment.</p>

Objective To evaluate the effect of oxidative injury induced by peroxide oxidase on Klotho expression in mouse renal tubular epithelial cells (TCMK-1) and to explore the possible pathway.Methods TCMK-1 cells were exposed to H2O2 of different concentrations.Reactive oxygen species (ROS) was examined byflow cytometrry.Cell viability was assessed by CCK-8.Cell apoptosis was evaluated by flow cytometry and Hoechst 33258 staining.The expression of Klotho,apoptosis-associated proteins and anti-oxidant enzymes were determined by Western blotting.Results Compared with control group,after H2O2 stimulating TCMK-1 cell,ROS was dramatically elevated (all P < 0.05) and the expression of anti-oxidant enzymes,SOD2 and CAT went down (all P < 0.05);the expression of Klotho was inhibited (all P < 0.05);cell viability of TCMK-1 cells was decreased (all P < 0.05) in a dose-dependent manner (0.3 to 0.9 mmol/L);cell apoptosis was significantly increased in TCMK-1 cells following the concentration of H2O2 (all P < 0.05);Bax/Bcl-2 and the phosphororation of JNK and p38 were obviously elevated in TCMK-1 by H2O2 induction (all P < 0.05).Conclusion Oxidative injuries induced by H2O2 significantly suppresses the expression of Klotho in TCMK-1 cells.And cell apoptosis was increased,p38 and JNK pathway was activated.
