Hemangiomas of the rib are extremely rare benign neoplasm. Here we present a case in a 47-year-old female, detected by chest X-ray and underwent a surgical resection. Histologically, the tumor was composed of a homogeneous conglomerate, irregular, thin walled and dilated blood vessels containing red blood cells, supported by fibrous stroma and intermingled to regular bone trabeculae. The postoperative courses were uneventful, and there was no recurrence during 64 months follow-up. © 2017 You-cai Zhu et al. 2017.

Background: EGFR tyrosine kinase inhibitors (TKIs) are widely used for advanced nonsmall cell lung cancer (NSCLC) patients with a sensitizing EGFR mutation and provide a promising treatment strategy. However, acquired resistance to EGFR-TKIs restricts their application. The mechanisms underlying acquired resistance to TKIs have been explored and Phosphoinositide 3- kinase (PI3K)/Akt/mTOR pathway plays a very important role in NSCLC development as well as EGFR-TKI resistance. Polyphyllin II(PP II) is the main steroidal saponin constituent which derives from the root of Paris polychylia. Objective: We examined the sensitizing effect of PP II to gefitinib on proliferation, apoptosis, PI3K/Akt/mTOR signaling pathway and tumor growth on gefitinib-resistant NSCLC in vitro and in vivo. Methods: Gefitinib-resistant PC-9/ZD cells and gefitinib-sensitive PC-9 cells were used. In the absence of PI3K siRNA, MTT assay, Annexin V/PI analyses, Western blot, and Immunohistochemistry analysis by TUNEL assays for xenograft model were carried out. Results: PP II promoted the anti-proliferative effects of gefitinib and gefitinib-induced apoptosis via activation of caspases and cleavage of PARP. PP II elevated sensitization of gefitinib through targeting the PI3K/Akt/mTOR. PP II with gefitinib treatment was more effective in inhibiting tumor growth and PI3K inactivation on gefitinib-resistant xenograft. Conclusion: The results indicated that PP II elevated sensitization of drug-resistant PC-9/ZD cells to gefitinib through the inhibition of PI3K/Akt/mTOR signaling pathway. It provides a potential new strategy to overcome gefitinib resistance for EGFR-TKI resistant NSCLC. © 2017 Bentham Science Publishers.

Nischarin is a cytoplasmic protein expressed in various organs that plays an inhibitory role in cell migration and invasion and the carcinogenesis of breast cancer cells. We previously reported that Nischarin is highly expressed in neuronal cell lines and is differentially expressed in the brain tissue of adult rats. However, the physiological function of Nischarin in neural cells remains unknown. Here, we show that Nischarin is expressed in rat primary cortical neurons but not in astrocytes. Nischarin is localized around the nucleus and dendrites. Using shRNA to knockdown the expression of endogenous Nischarin significantly increases the percentage of neurite-bearing cells, remarkably increases neurite length, and accelerates neurite extension in neuronal cells. Silencing Nischarin expression also promotes dendrite elongation in rat cortical neurons where Nischarin interacts with p21-activated kinase 1/2 (PAK1/2) and negatively regulates phosphorylation of both PAK1 and PAK2. The stimulation of neurite growth observed in cells with decreased levels of Nischarin is partially abolished by IPA3-mediated inhibition of PAK1 activity. Our findings indicate that endogenous Nischarin inhibits neurite outgrowth by blocking PAK1 activation in neurons. © 2015 Ding et al.

Study objective To evaluate effect of parecoxib sodium pretreatment combined with dexmedetomidine on early postoperative cognitive dysfunction in elderly patients after shoulder arthroscopy. Design Randomized, double-blind study. Setting University-affiliated teaching hospital. Patients One hundred and fifty-two elderly patients scheduled for shoulder arthroscopy. Interventions At 15 min before the induction of anesthesia, 152 patients received intravenously parecoxib sodium 40 mg and dexmedetomidine at a dose of 0.5 μg/kg over 15 min, followed by a continuous infusion at a rate of 0.5 μg/kg/h until the end of surgery. Then all patients who received postoperative patient-controlled intravenous analgesia were divided 2 groups: sufentanil(0.04μg/kg/h, S group), sufentanil (0.04μg/kg/h) plus dexmedetomidine(0.06μg/kg/h) (SD group). Measurements The mini–mental status examination score in SD group was significantly higher than S group at 1, 2 and 7 days after surgery. The incidence of postoperative cognitive dysfunction during 7 days after surgery in S and SD groups was respectively 17.1% and 6.7%. Compared with the S group, the visual analogue scale scores at rest and upon movement were significantly lower at 6, 14, 24, 36 and 48 h after surgery in SD group; analgesia pump liquid amount during 24 h after surgery and number of rescue analgesia during 48 h after surgery were significantly lower in SD group. Jugular venous oxygen partial pressure and jugular venous oxygen saturation values in SD group were significantly higher than S group at postoperative 24 h. The occurrence of nausea and vomiting within 48 h after surgery in SD group were significantly lower than S group. We found no complications including respiratory depression and sinus bradycardia within 48 h after surgery in all patients. Conclusions Parecoxib sodium pretreatment combined with dexmedetomidine could reduce the incidence of early postoperative cognitive dysfunction in elderly patients. This might be related to the improvement of postoperative analgesia effect and cerebral oxygen metabolism in patients. © 2017

Aim: Nuclear factor-erythroid 2-related factor-2 (Nrf2) acts as a defense system in the development of nonalcoholic steatohepatitis (NASH). Curcumin is a phenolic compound with lipid regulatory, anti-oxidative, anti-inflammatory and anti-tumorigenic properties that is beneficial in defending against NASH and was recently proved to be an Nrf2 activator. The aim of this study was to evaluate whether Nrf2 activation could be involved in NASH mitigation by curcumin. Methods: Hepatic, metabolic, and inflammatory parameters, along with hepatic Nrf2 protein expression were explored in adult Sprague–Dawley rats developing high-fat-diet-induced NASH and submitted to curcumin gavage for 6 weeks. Results: Curcumin administration led to lower degrees of hepatic steatosis and inflammation; lower levels of serum aminotransferases, lipids, and homeostasis model assessment of insulin resistance; and lower serum and hepatic contents of tumor necrosis factor-α (TNF-α), interleukin-6, and malondialdehyde. In contrast, higher hepatic contents of glutathione, heme oxygenase-1 and superoxide dismutase were observed in rats with curcumin. Moreover, Nrf2 expression in liver cell nuclei was significantly higher in rats with curcumin. Conclusions: Curcumin can prevent and ameliorate NASH via lipid reduction, improve insulin resistance, improve anti-inflammatory, and have antioxidant effects, possibly related to its activation of Nrf2. © 2014, Royal Academy of Medicine in Ireland.

BACKGROUND: In root canal preparation, the clearance effect of sodium hypochlorite for root canal irrigation on the smear layer is associated with the contact time and contact area of irrigation fluid, the amount of irrigation fluid, irrigation fluid temperature, irrigation fluid concentration, flushing methods and so on. OBJECTIVE: To investigate the clearance effect of 3% sodium hypochlorite on the smear layer of root canal under different flushing methods, flushing temperature and flushing time. METHODS: Totally 180 isolated front teeth with single root were collected and root canal preparation was conducted using motorized ProTaper. The root canal was flushed with 3% sodium hypochlorite. According to different flushing methods, these root canals were randomly and evenly divided into root canal active flushing group, passive ultrasound swished group and side opening flushing needle group. According to the flushing temperature and the flushing time after replacing a file, each group was randomly divided into six subgroups: 20 °C 30 seconds group, 20 °C 60 seconds group, 37 °C 30 seconds group, 37 °C 60 seconds, 60 °C 30 seconds group and 60 °C 60 seconds group. The clearance effect on the smear layer of root canal was observed using scanning electron microscope. RESULTS AND CONCLUSION: The general clearance effect on the smear layer in the root canal active flushing group was better than that in the passive ultrasound swished group and side opening flush acupuncture group (P < 0. 05). At the same time, the clearance effect on the smear layer in the 60 °C group was better that that in the 37 °C group and 20 °C group (P < 0. 05). At a certain temperature, the clearance effect on the smear layer in 60 seconds group was better than that in the 30 seconds group (P < 0. 05). The clearance effect on the smear layer in the 1/3 root cap zone was better than that in the 1/3 root and 1/3 apical root zone (P < 0. 05). These results show that the best clearance effect on the smear layer can be achieved as follows: 3% sodium hypochlorite irrigation at 60°C for 60 seconds. © 2015, Journal of Clinical Rehabilitative Tissue Engineering Research.

Objective: To explore the establishment of a fibrosis model in vitro by inducing rat myoblast C2C12 by transforming growth factor-β (TGF-β), observe the effects of variations of the miRNA138 level on cell fibrosis indexes, and analyze whether the effects of miRNA138 on cell fibrosis was achieved by its target gene Smad4. Methods: The miRNA138-mimics, miRNA138-inhibitor, and miRNA138-NC were designed, synthesized and transfected into C2C12 cells by lipofectminae. Transfected cells were then induced by TGF-β1 of 10 ng/mL for 48 h. The expression of miRNA138 was detected by Real-time PCR. The variations of expressions of fibrosis related proteins Smad4, vimentin, α-SMA, and collagen I were detected by the Western blotting to verify whether the fibrosis model had been successfully established and analyze the effects of variations of the miRNA 138 expression on cell fibrosis indexes. The effects of variations of the miRNA 138 expression on the proliferation activity of C2C12 during the course of fibrosis were measured by the CCK-8. Bioinformatic software was used to analyze the theoretical binding site of miRNA138 and Smad4, which was verified by the luciferase reporter gene test. The Smad4 gene expression vector was constructed and co-transfected into C2C12 cells with miRNA-mimics. Transfected cells were induced by TGF-β1 for fibrosis. The variations of fibrosis related proteins were detected by the Western blotting and the effects of expression of exogenous Smad4 on the inhibition of cell fibrosis by miRNA138 were analyzed. Results: The expression of miRNA138 significantly increased after C2C12 cells were transfected by miRNA138-mimics and decreased after C2C12 cells were transfected by miRNA138-inhibitor. The expression of miRNA138 of the control group had no significant changes. Results: of protein detection showed that expressions of Smad4, vimentin, α-SMA, and collagen I were significantly increased and the cell proliferation activity in logarithmic phase was enhanced after C2C12 cells were induced by TGF-β1 for 48 h, which indicated that the cell fibrosis model was successfully established. The over-expression of miRNA138 significantly inhibited the fibrosis of C2C12 cells. The data of luciferase activity detections showed that the predicted binding site of miRNA138 and Smad4 existed. High expression of exogenous Smad4 in C2C12 cells significantly impaired the inhibition of cell fibrosis by miRNA138-mimics.Conclusion: MiRNA138 can inhibit the fibrosis of C2C12 cells induced by TGF-β1 via suppressing the expression of its target protein Smad4. ©, 2015, Editorial Department of Journal of Shanghai Second Medical University.

Backgrounds. Segmental and circumferential pulmonary vein isolations (SPVI and CPVI) have been demonstrated to be effective therapies for paroxysmal atrial fibrillation (PAF). PVI is well established as the endpoint of different ablation techniques, whereas it may not completely account for the long-term success. Methods. 181 drug-refractory symptomatic PAF patients were referred for segmental or circumferential PVI (SPVI = 67; CPVI = 114). Heart rate variability (HRV) was assessed before and after the final ablation. Results. After following up for 62.23±12.75 months, patients underwent 1.41±0.68 procedures in average, and the success rates in SPVI and CPVI groups were comparable. 119 patients were free from AF recurrence (SPVI-S, n=43; CPVI-S, n=76). 56 patients had recurrent episodes (SPVI-R, n=21; CPVI-R, n=35). Either ablation technique decreased HRV significantly. Postablation SDNN and rMSSD were significantly lower in SPVI-S and CPVI-S subgroups than in SPVI-R and CPVI-R subgroups (SPVI-S versus SPVI-R: SDNN 91.8±32.6 versus 111.5±36.2 ms, rMSSD 47.4±32.3 versus 55.2±35.2 ms; CPVI-S versus CPVI-R: SDNN 83.0±35.6 versus 101.0±40.7 ms, rMSSD 41.1±22.9 versus 59.2±44.8 ms; all P<0.05). Attenuation of SDNN and rMSSD remained for 12 months in SPVI-S and CPVI-S subgroups, whereas it recovered earlier in SPVI-R and CPVI-R subgroups. Multivariate logistic regression analysis identified SDNN as the only predictor of long-term success. Conclusions. Beyond PVI, denervation may be a common mechanism underlying different ablation strategies for PAF. © 2013 Kejing Wang et al.

Background: Intravertebral cleft is a structural change in osteoporotic vertebral compression fractures (OVCF), which is the manifestation of ischemic vertebral osteonecrosis complicated with fracture nonunion and pseudoarthrosis and appears in the late stage of OVCF. Despite numerous studies on OVCF, few aim to evaluate the clinicoradiological characteristics and clinical significance of intravertebral cleft in OVCF. This study investigates clinicoradiological characteristics of intravertebral cleft in OVCF and the effect on the efficacy of percutaneous balloon kyphoplasty (PKP). Materials and Methods: PKP was performed on 139 OVCF patients without intravertebral cleft (group A) and 44 OVCF patients with intravertebral cleft (group B). The frequency distribution of the affected vertebral body, bone cement infusion volume, imaging manifestation, leakage rate and type, preoperative and postoperative height of the affected vertebral body, visual analog scale (VAS) and Oswestry disability index (ODI) score were evaluated. Results: Significant differences were found in the frequency distribution of the affected vertebral body and bone cement leakage type between the two groups (P < 0.05). However, differences in bone cement infusion volume and leakage rate (P > 0.05) were not detected. In both groups, the postoperative height of the affected vertebral body was significantly improved (P < 0.05). The restoration of vertebral body height in group B was more evident than that in group A (P < 0.05). The preoperative VAS and ODI scores in group B were significantly higher than those in group A (P < 0.05). After surgical treatment, pain relief and daily activity function in both groups were significantly improved (P < 0.05), and no significant difference in postoperative scores was detected between the two groups (P > 0.05). Conclusion: Intravertebral cleft exhibits specific clinical and imaging as well as bone cement formation characteristics. PKP can effectively restore the affected vertebral body height, alleviate pain, and improve daily activity function of patients.
