OBJECTIVE Esophageal squamous cell carcinoma (ESCC) is the most malignant type of esophageal cancer. Although significant advances have been made in ESCC diagnosis and therapy, its poor pathogenesis and prognosis remain a life-threatening problem. Meanwhile, long noncoding RNAs (lncRNAs) exert a pivotal function in tumorigenesis. In this research, we aimed to explore the association between the aberrant expression of lncRNA DLX6-AS1 and the development and metastasis of ESCC. PATIENTS AND METHODS DLX6-AS1 expression was monitored by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) in ESCC specimens. Moreover, experiments were conducted to detect the effect of DLX6-AS1 on the cell proliferation and metastasis of ESCC. In addition, the underlying mechanism was further explored through luciferase assays and RNA immunoprecipitation assay (RIP). RESULTS DLX6-AS1 expression level was significantly higher in ESCC specimens. Moreover, cell proliferation and metastasis of ESCC cells could be inhibited via reducing DLX6-AS1 expression. Besides, DLX6-AS1 was regarded as an oncogene in ESCC. Furthermore, DLX6-AS1 acted as a competing endogenous RNA via sponging miR-577 in ESCC. CONCLUSIONS In summary, DLX6-AS1 promotes development and metastasis of ESCC by sponging miR-577 and could be a potential therapeutic target.OBJECTIVE To investigate the effect of GREM1 on the sensitivity of cervical squamous carcinoma cells to radiotherapy and chemotherapy. PATIENTS AND METHODS The resected cancer tissues and paracancerous tissues of patients with cervical carcinoma were collected. The expressions of GREM1 protein and mRNA in SiHa cell line of cervical squamous carcinoma were tested by Western blot and reverse transcription-polymerase chain reaction (qRT-PCR). The effect of GREM1 on chemotherapy sensitivity of SiHa cells was tested by MTT assay. SiHa cells were irradiated with different doses of X-ray, and the changing trend of GREM1 in cell lines was observed. RESULTS Compared with paracancerous tissues, the expression level of GREM1 in cervical squamous carcinoma was significantly higher than that in paracancerous tissues (p less then 0.05). After adding different concentrations of chemotherapeutic drugs, the relative survival rate of SiHa cells overexpressing GREM1 group was significantly increased. After high-energy X-ray irradiation with different radiation doses of SiHa cells, the expression levels of GREM1mRNA and protein in SiHa cell lines showed a significant downward trend. GREM1 was highly expressed in cervical squamous carcinoma. CONCLUSIONS Down-regulating GREM1 expression can increase the chemotherapy sensitivity of SiHa cells. GREM1 may be related to the radiotherapy sensitivity of cervical squamous carcinoma.OBJECTIVE To study the effect of strontium ranelate (SR) on steroid-induced osteonecrosis of the femoral head (SIONFH) in rabbits and its regulatory mechanism. MATERIALS AND METHODS The ONFH model was established in 30 rabbits using steroid and they were randomly divided into Control group, Model group, and SR group. After SR intervention, the rabbits were sacrificed and sampled. The pathological injury of the femoral head in each group was detected via hematoxylin-eosin (HE) staining, the level of vascular endothelial growth factor (VEGF) in the femoral head in each group was detected via enzyme-linked immunosorbent assay (ELISA). The messenger ribonucleic acid (mRNA) and protein expression levels of transforming growth factor-β1 (TGF-β1), as well as the bone morphogenetic protein 2 (BMP2) in the femoral head in each group, were determined using Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Western blotting. RESULTS The rabbit model of SIONFH was successfully established. Compared with Control group, the Model group had a severer pathological injury of the femoral head, a lower level of VEGF in the femoral head, significantly decreased mRNA and protein levels of TGF-β1 and BMP2. Compared with Model group, the SR group had markedly improved pathological injury of the femoral head, a higher level of VEGF in the femoral head, significantly increased mRNA and protein levels of TGF-β1, as well as BMP2. see more CONCLUSIONS SR can remarkably improve the pathological injury of the femoral head and increase the expression of VEGF in SIONFH rabbits, whose potential mechanism may be related to the activation of the TGF-β1/BMP2 signaling pathway.OBJECTIVE Protein-energetic malnutrition (PEM) affects prognosis and mortality in elderly patients as an inadequate nutritional status is a risk factor for the development and worsening of pressure sores (PS). We aimed to evaluate the incidence of PEM in outpatients with PS and to study the impact of nutritional support on the stage of PS. PATIENTS AND METHODS PS patients, divided in a group treated with artificial nutrition (group A) and those fed orally (group B) at home, were consecutively enrolled in the Integrated Home Care program of Ascoli Piceno between June and September 2015. At T0 the patients underwent medical history, nutritional, anthropometric/biochemical parameters assessment, and the staging of the PS. The same assessments and staging of the pressure lesions were performed three months later (T1). RESULTS Group A (n=25) started from a better nutritional status vs. group B (n=25) at T0, according to MNA assessment. Group A showed a significant improvement of nutritional status correlating with detailed control of nutrients intake and improvement of PS stage (T0 vs. T1, p less then 0.05). On the other hand, group B showed a significant difference between nutrients intake and nutritional needs that correlated with both malnutrition state increase and worsening of the PS staging (T0 vs. T1, p less then 0.05). CONCLUSIONS The present study shows that PEM has a significant prevalence in the elder, in general, and in older people with PS, in particular. A targeted nutritional intake can prevent and help the healing of PS.OBJECTIVE This review inspects the relations between the microbiota and the intestinal immune system in the advancement of metabolic illnesses, such as obesity and diabetes mellitus. The role of the microbiota in intestinal immune defense and the control of metabolism are subject to examination. MATERIALS AND METHODS In type 1 diabetes, the adhesion proteins prompt inside the intestinal epithelium prompt a more significant immune response that may result in the destruction of pancreatic β cells by CD8+ T-lymphocytes, as well as increased articulation of interleukin-17, which is associated with autoimmunity. Studies suggest that the beginning of metabolic ailments and certain co-morbidities can be viewed in light of the protection between the gut microbiota and the intestinal immune system. The gut microbiota is analyzed as a key regulator of metabolic ailments. Research demonstrates that obese patients with type 2 diabetes have a certain gut microbiota and that the microbiota is translocated from the gut to the tissues in conjunction with the illness, which instigates inflammation. RESULTS Research in animals and people suggests that a probiotic supplement may regulate the gut microbiota, thereby improving the prognosis for diabetes. CONCLUSIONS The mechanism underlying this phenomenon relates to a decrease in the inflammatory reaction and oxidative stress, as well as a decrease in leaky gut. Such reactions increase insulin sensitivity and reduce autoimmune responses.OBJECTIVE To assess whether the hop-derived polyphenol isoxanthohumol suppresses insulin resistance by changing the intestinal microbiota. MATERIALS AND METHODS Male C57BL/6J mice (7 weeks of age) were divided into five groups (n = 9-10) Normal Diet (ND), High Fat Diet (HFD), HFD + low dose isoxanthohumol (0.01%IX), HFD + medium dose isoxanthohumol (0.03% IX), and HFD + high dose isoxanthohumol (0.1% IX). Oral glucose tolerance tests (OGTTs) were performed at 4 and 8 weeks, and insulin tolerance tests (ITTs) were performed at 13 weeks. 16S rRNA gene sequencing analyses revealed the fecal microbiota profiles, and the relative abundance of Akkermansia muciniphila and Clostridium cluster XI was calculated by qRT-PCR. Plasma lipopolysaccharide (LPS) levels were measured by ELISA, and mRNA expression levels of tumor necrosis factor (TNF)-α, and interleukin (IL)-1β in epididymal adipose tissues were measured by qRT-PCR. RESULTS Isoxanthohumol showed antibacterial activity towards several bacterial species and mitigated impaired glucose tolerance and insulin resistance induced by the HFD in a dose-dependent manner, as shown by OGTTs and ITTs. The concentration of phylum Verrucomicrobia bacteria dramatically increased in the 0.1% IX group, the relative abundance of A. muciniphila increased, and that of Clostridium cluster XI decreased. Moreover, the intake of isoxanthohumol decreased the levels of plasma LPS and mRNA expression of TNF-α and IL-1β in epididymal adipose tissues. CONCLUSIONS We found that isoxanthohumol can suppress HFD-induced insulin resistance by changing the intestinal microbiota and reducing the expression of inflammation factors.OBJECTIVE To investigate the roles and underlying mechanisms of melatonin in oxygen-glucose deprivation/reoxygenation (OGD/R)-insulted SH SY5Y cells. MATERIALS AND METHODS SH SY5Y cells were cultured for OGD/R stimulation. Cell viability and cytotoxicity were measured by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide, lactate dehydrogenase (LDH), and Hoechst 33258/propidium iodide (PI) staining assays. The mRNA levels of high mobility group box-1 (HMGB1), tumor necrosis factor α (TNF-α), and inducible nitric oxide synthase (iNOS) were analyzed by quantitative Real Time-PCR assays. Nitric oxide (NO) production was assessed by Griess reagent. Reactive oxygen species (ROS) production was detected by fluorescent probe. Malondialdehyde (MDA), 4-hydroxynonenal (4-HNE), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were examined by commercial kits. Cell apoptosis was analyzed by flow cytometry and caspase-3 activity. The protein levels were detected by Western blot. RESULTS Melatonin enhanced the viabilityed oxidative stress, inflammation, apoptosis, and autophagy by blocking NF-κB signaling and activating Nrf2/HO-1, Akt, and mTOR/p70S6K/4E-BP-1 pathways, thereby indicating that melatonin is a potential and novel therapeutic drug for ischemic stroke.OBJECTIVE To investigate the effect of bone marrow mesenchymal stem cells (BMSCs) on repairing brachial plexus injury in rabbits and their influence on expression of the extracellular signal-regulated kinase (ERK) pathway. MATERIALS AND METHODS With big-ear rabbits as the objects, the BMSCs were first isolated, and the cluster of differentiation (CD)45- and CD90+ BMSCs were sorted out via flow cytometry. BMSCs were transfected with red fluorescent protein (RFP), and the transfection effect was detected. Then, the big-ear rabbits were subjected to brachial plexus root avulsion injury (BPAI) to establish injury Model group and sham-operation group (Sham group). Later, the BMSCs were transfected with RFP to construct RFP-BMSCs. The RFP-BMSCs (5×106, Treat group) and normal saline (Model group) were intraperitoneally injected, and the recovery rate of wet weight of the upper limb muscle was measured by weighing. The injured nerve tissues were embedded for hematoxylin and eosin (HE) staining and observation of pathological changes.
