Achalasia is an esophageal motility disorder with impaired relaxation of lower esophageal sphincter.Its clinical manifestations are progressive dysphagia, retrosternal pain, regurgitation of undigested food, weight loss.Medication, endoscopic treatment and surgery are the main treatments of achalasia.Peroral endoscopic myotomy (POEM) is an endoscopic mini-invasive technique which has smaller surgical injury, remarkable curative effect, lower cost, and lower recurrence rate when compared with the traditional treatment of achalasia.This article reviewed the advances and prospects of POEM in treatment of achalasia.

AIM: To optimize the extraction process for Banxiaxiexin Decoction (Rhizoma pinelliae, Radix Scutellariae, Rhizoma coptidis, Radix Ginsenp, Rhizoma zinpiberis, Fruents Jujubae, and Radix Glycyrrhizae). METHODS: The content of berberine、baicalin and total solid in extract liquor were determined by orthogonal design and single factor experiment in combination with glycyrrhizic acid content and identification of Rhizoma zingiberis, Radix Ginseng and Rhizoma Pinelliae. RESULTS: The extracting was arrived at in the condition of adding eighteen times of 70% alcohol as much as crude drug and refluxing 2 times, 2h and 1h, respectively. CONCLUSION: The extraction is stable and feasible.

Pemphigus is a severe chronic autoimmune mucocutaneous bullous disease. Glucocorticoids are considered as the first line of treatment for this disease. Dysfunctional uterine bleeding is also observed as a result of hypothalamic-pituitary-ovary axis dysfunction. This study reported one female patient with pemphigus vulgaris complicated with dysfunctional uterine bleeding upon systemic glucocorticoid usage. Before this disease was diagnosed, the patient experienced normal menstruation. The mechanism of dysfunctional uterine bleeding triggered by glucocorticoids is elucidated on the basis of case studies and literature review.

The ubiquitin-proteasome pathway is responsible for the degradation of most cellular proteins in eukaryotes.It regulates almost all cellular activities, including cell proliferation, differentiation, apoptosis, gene transcription, and DNA repair.The dysfunction of the ubiquitin-proteasome pathway is associated with the pathogenesis of numerous human diseases, including cancer and neurodegenerative diseases.The marketed proteasome inhibitors have been successfully used to treat multiple myeloma and mantle cell lymphoma.Furthermore, novel inhibitors against the components of the ubiquitin-proteasome pathway are under developed and exhibit promising therapeutic effects in vivo.This paper will briefly introduce the progress on the drug discovery related to the ubiquitin-proteasome pathway.

AIM: To investigate the effects of proteasome inhibitor Z-LLL-CHO(MG132) on human osteosarcoma cell line MG-63 and its possibly mechanism.METHODS: After treated with different concentration of MG132,the morphological change,ultrastructral morphology,cell viability,cell apoptosis,gene transcription and protein expression in MG-63 cells were accessed by fluorescence microscope,electron microscope,MTT assay,agrose gel electrophoresis,FCM,RT-PCR and Western blotting.RESULTS: Proteasome inhibitor MG132 was an effective inducer of apoptosis in human osteosarcoma MG-63 cells.Not only apoptotic changes,but also cell arrest at G2-M-phase,the accumulation of p27kip1,the accumulation of activated caspase-8 and increased ratio of Bax∶Bcl-2 were observed.However,to normal human diploid fibroblast cells,MG132 did not show apoptosis-inducing effect.CONCLUSION: Apoptosis induced by MG132 may be caspase-8,p27kip1and bcl-2-related.

Background:Esophageal cancer is a digestive system malignant tumor with high incidence in China. Early diagnosis and treatment are the keys to increase the survival rate of patients with esophageal cancer. Now,applying magnifying endoscopy combined with narrow-band imaging(ME-NBI)for diagnosis of early esophageal cancer has become the hot research spot. Aims:To evaluate the diagnostic value of ME-NBI for early esophageal cancer and its invasive depth. Methods:Consecutive patients with early esophageal cancer or precancerous lesion undergoing conventional white light endoscopy with biopsy and ME-NBI from June 2013 to November 2015 at the Ren Ji Hospital,School of Medicine, Shanghai Jiao Tong University were collected retrospectively. The findings of ME-NBI and biopsy pathology of conventional white light endoscopy were comparatively analyzed. The accuracy of ME-NBI in diagnosis of invasive depth of early esophageal cancer was evaluated. Results:A total of 49 patients were enrolled. The overall agreement of ME-NBI findings with endoscopic surgical pathology(gold standard)as well as the sensitivity and negative predictive value of ME-NBI for differentiating early esophageal cancer and precancerous lesion were significantly higher than those of biopsy pathology under conventional white light endoscopy[91. 8%(45 / 49)vs. 24. 5%(12 / 49);100%(45 / 45)vs. 17. 8%(8 / 45);100%(3 / 3)vs. 9. 8%(4 / 41),P all < 0. 05]. Total accuracy of ME-NBI for diagnosing the invasive depth of early esophageal cancer was 77. 8%(35 / 45). Conclusions:ME-NBI has good diagnostic value for early esophageal cancer and its depth of invasion. It can be used as an effective modality for clinical diagnosis of early esophageal cancer.

Objective Dipole source analysis was employed to investigate the transient changes in brain mechanisms at earlier latencies.Methods Fourteen healthy volunteers were recruited in this research and evoked event-related potentials (ERPs) of unimodal and bimodal visual auditory stimuli were recorded by 64-electrodes electroencephalograph (EEG) recording system.All these earlier phases of the stimuli were divided into several subphases by specific time window for source analysis.Results The results showed that ERPs sources were mainly generated from visual and audio cortex,and there were changes in the location and strength of the dipole sources in each sub-phase.Conclusions The result of this study implies a serial processing of sensory information in human cortices in early phase of visual and auditory stimuli.

BACKGROUND:Nano-hydroxyapatite/bacterial celulose (nHA/BC) composite scaffolds prepared by nano-bionics method exhibit a structure and performance similar to natural bone. OBJECTIVE:To study the cytotoxicity and biocompatibility of nHA/BC composite scaffolds. METHODS:(1) Acute systemic toxicity test: nHA/BC leach liquor and normal saline were respectively injected intraperitonealy into Kunming mice. After 24, 48, 72 hours, the body mass of mice was recorded. (2) Sensitization test: nHA/BC leach liquor and normal saline were respectively injected subcutaneously into the back of Japanese white rabbits. With 72 hours of injection, edema and erythema were observed, and the experiment was done again at an interval of 14 days. (3) Pyrogen test: nHA/BC leach liquor and normal saline were respectively injected into the ear vein of Japanese white rabbits, and after injection, the body temperature of rabbits were determined. (4) Hemolysis test: Diluted rabbit anti-coagulant was added into nHA/BC leach liquor, normal saline and distiled water, respectively. (5) Passage 3 bone marrow mesenchymal stem cels from rabbits were co-cultured with nHA/BC materials, and then, cel proliferation, growth and adhesion on the material surface were observed. RESULTS AND CONCLUSION: nHA/BC composite scaffold was of no acute systemic toxicity, non-alergenic, no pyrogenic and hemolytic reactions; nHA/BC had a three-dimensional porous structure that was better for growth, proliferation and adhesion of rabbit bone marrow mesenchymal stem cels. These findings indicate that the nHA/BC composite scaffold has good biocompatibility and cytocompatibility.

Objective To explore the regulatory effect of miRNA on B-cell activating factor (BAFF) in chronic eosinophilic rhinosinusitis with nasal polyp (Eso CRSwNP).Methods Ten nasal mucosal samples were collected from Eso CRSwNP patients who were admitted and treated in our hospital between January 2012 and February 2013.Normal nasal mucosal tissues (n =10) served as control.The miRNA-targeting BAFF was predicted by bioinformatics tools.Immunohistochemistry and real time polymerase chain reaction (RT-PCR) were used to assess the protein expression of BAFF and the predicted miR-NA.The correlation between the predicted miRNA and BAFF was analyzed.Results Down-regulated expression of let-a was confirmed in Eos CRSwNP,while the BAFF protein expression was increased.Let-a was positively correlated with BAFF in nasal epithelia.Conclusions Let-a might contribute to mucosal eosinophilia in eosinophilic CRSwNP via targeting BAFF.
