Actin-binding proteins (ABPs) are important components of the F-actin cytoskeleton and affect the dynamics of F-actin by promoting the polymerization and depolymerization of actin. Numerous studies have shown that F-actin and actin-binding proteins are involved in all stages of carcinogenesis. Our analysis of esophageal carcinoma proteomic data showed that the actin-binding protein EHD2 (E p s l 5 homology domain-containing protein 2) is expressed at low levels in esophageal squamous cell carcinoma tissues and patients with lower EHD2 expression had poorer prognosis. Previous studies have revealed that EHD2 is involved in the regulation of glucose metabolism, autophagy and tumor cell migration. However, the role and mechanism of EHD2 in esophageal squamous cell carcinoma progression remain unclear. This study aimed to explore the effect of EHD2 on the proliferation of esophageal squamous cell carcinoma. Immunofluorescence and cell fractionation analysis showed that EHD2 was not only localized in the cell membrane and cytoplasm, but also in the nucleus. Colony formation, EdU labeling and flow cytometry were used to determine the effect of EHD2 on the proliferation of esophageal squamous cell carcinoma. The results showed that overexpression of EHD2 and EHD2-3×NLS (nuclear localization signal) inhibited proliferation, cell cycle G

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

A new fungus, Ophiocordyceps alboperitheciata, parasitic on the larva of Noctuidae (Lepidoptera) was identified from a survey of entomopathogenic fungi in Kunming Wild Duck Forest Park, Yunnan Province, China. It can be primarily distinguished from relatives by its longer fertile parts, sterile tips, superficial perithecia, narrower asci, and smaller septa of ascospores. As revealed from phylogenetic analyses inferred from nrSSU, nrLSU, tef-1α, rpb1, and rpb2 sequence data, O. alboperitheciata belongs to the Hirsutella citriformis clade in the genus Ophiocordyceps of Ophiocordycipitaceae, and forms a separated clade from other related species. The uniqueness of the taxon is significantly evidenced by both molecular phylogeny and morphology. Furthermore, the interspecific relationships in the H. citriformis clade are discussed.

OBJECTIVE: To evaluate the clinical outcome of tibiotalocalcaneal fusion using cannulated screw and humeral proximal locking plate inverted fixation through a lateral transfibular approach. METHODS: From June 2015 to December 2018, 15 patients underwent a tibiotalocalcaneal fusion operation using cannulated screw and inverted proximal humerus locking plate through a transfibular approach. There were 10 males and 5 females with the age ranging from 45 to 72 (58.9±6.1) years, and the course of disease ranged from 2 to 35 (11.9±7.9)years. Preoperative diagnosis included 8 cases of post traumatic arthritis, 2 cases of Charcot arthritis, 2 cases of Charcot-Marie -Tooth (CMT), 1 case of ankle tuberculosis, 1 case of talar necrosis, and 1 case of pigmented villonnodular synovitis. Among them, 8 patients were combined with simple varus deformity, 4 patients with simple valgus deformity, 2 patients with equinovarus deformity, 1 patient with equinovarus deformity, 2 patients with adduction and internal rotation of middle and forefoot. American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and the visual analogue scale (VAS) score were used to evaluate the clinical outcome at the last follow up. RESULTS: One lost follow up and remaining fourteen patients were followed up. The follow up time ranged from 10 to 25(16.6±4.3) months. All the 15 patients had primary healing. Fusion time ranged from 15 to 24 (16.8 ± 2.4) weeks after operation. One patient with diabetes experienced delayed union and was successfully treated with secondary bone grafting combined with Platelet-Rich Plasma (PRP) injection. The AOFAS score increased from 38.7±3.3 to 84.5±2.6 ( CONCLUSION Tibiotalocalcaneal fusion used cannulated screw and humeral proximal locking plate inverted fixation through a lateral transfibular approach has the advantages of relatively simple technique, high fusion rate, especially for patients with posterior foot deformity, which has satisfactory short term effects.

OBJECTIVE: To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients. METHODS: A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented. RESULTS: The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns. CONCLUSION Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).

Insulin-like growth factor-1 receptor (IGF-1R) is involved in both glucose and bone metabolism. IGF-1R signaling regulates the canonical Wnt/β-catenin signaling pathway. In this study, we investigated whether the IGF-1R/ β-catenin signaling axis plays a role in the pathogenesis of diabetic osteoporosis (DOP). Serum from patients with or without DOP was collected to measure the IGF-1R level using enzyme-linked immunosorbent assay (ELISA). Rats were given streptozotocin following a four-week high-fat diet induction (DOP group), or received vehicle after the same period of a normal diet (control group). Dual energy X-ray absorption, a biomechanics test, and hematoxylin-eosin (HE) staining were performed to evaluate bone mass, bone strength, and histomorphology, respectively, in vertebrae. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting were performed to measure the total and phosphorylation levels of IGF-1R, glycogen synthase kinase-3β (GSK-3β), and β-catenin. The serum IGF-1R level was much higher in patients with DOP than in controls. DOP rats exhibited strikingly reduced bone mass and attenuated compression strength of the vertebrae compared with the control group. HE staining showed that the histomorphology of DOP vertebrae was seriously impaired, which manifested as decreased and thinned trabeculae and increased lipid droplets within trabeculae. PCR analysis demonstrated that IGF-1R mRNA expression was significantly up-regulated, and western blotting detection showed that phosphorylation levels of IGF-1R, GSK-3β, and β-catenin were enhanced in DOP rat vertebrae. Our results suggest that the IGF-1R/β-catenin signaling axis plays a role in the pathogenesis of DOP. This may contribute to development of the underlying therapeutic target for DOP.

BACKGROUND: Chinese medicine is effective for preventing and treating glucocorticoid-induced osteoporosis, however, the underlying mechanism remains unclear. DKK1, an inhibitor of Wnt/β-catenin signaling pathway, can be up-regulated by glucocorticoid. Thereafter, DKK1 is an important target in the prevention and treatment of osteoporosis. OBJECTIVE: To explore the regulatory effect of Zuogui pill on DKK1 in the prevention and treatment of glucocorticoid-induced osteoporosis. METHODS: Eighteen three-month-old female Sprague-Dawley rats were randomly divided into three groups: control group, model group and Zuogui pill group. Rats in the model and Zuogui pill groups received the subcutaneous injection of dexamethasone to establish the model of glucocorticoid-induced osteoporosis. The Zuogui pill group rats were administrated Zuogui pill extracts, and the control rats were given the same volume of normal saline. At 1 month after modeling, the lumbar vertebrae were removed to test the bone mass and microstructures by micro-CT scanning. The biomechanical properties were detected by compression test. The mRNA expression levels of DKK1, Runx2 and CTSK were determined by Qpcr. The serum alkaline phosphatase activity was tested. RESULTS AND CONCLUSION: Compared with the control group, in the model group, the volumetric bone mineral density, trabecular bone volume fraction, trabecular number, and trabecular thickness were significantly decreased (P ＜ 0.05), the trabecular separation and structure model index were significantly increased (P ＜ 0.05). The serum alkaline phosphatase activity was on a decline. The mRNA expression level of DKK1 showed a significant up-regulation (P ＜ 0.05). The mRNA expression level of Runx2 showed a down-regulated trend while mRNA expression level of CTSK showed an up-regulated trend. Compared with the model group, the Zuogui pill group showed significantly enhanced volumetric bone mineral density, trabecular bone volume fraction, and trabecular number (P ＜ 0.05); the structure model index was significantly decreased (P ＜ 0.05); the trabecular separation was reduced; the serum alkaline phosphatase activity was enhanced; the mRNA expression level of DKK1 showed a significant down-regulation (P ＜ 0.05); the mRNA expression level of Runx2 showed an up-regulated trend while mRNA expression level of CTSK showed a down-regulated trend. The vertebral compressive strength in the Zuogui pill group was significantly higher than that in the model group (P＜0.05). In summary, Zuogui pill prevents and treats glucocorticoid-induced osteoporosis possibly through the down-regulation of mRNA expression of DKK1.
