Objective:To investigate the effect of continuous blood purification on the expression of cytokines in pig lungs during MODS.Methods:Twenty-five pigs were randomly divided into model group,control group and high volume hemofiltration(HVHF) group.Blood bio-chemical and organ function indexes were determined.Real-time quantitative PCR was used to determine the expression level of IL-6 mRNA and IL-8 mRNA and TNF-? mRNA. Results:After HVHF,the serum chemical and organ-function indexes were improved and the morbidity and mortality of MODS were much lower than those in model group.The expression level of IL-6 mRNA and IL-8 mRNA and TNF-? mRNA in the lung were reduced significantly compared with model group.And the expression level of cytokines associated mRNA in the lungs was interrelated with the rate of respiratory failure. Conclusion:HVHF could decrease the over-expression of cytokine mRNA in the lung after trauma when used at early period so that pulmonary function would be improved.

Objective To analyze clinical features and surgical treatment of thyroglossal duct cyst (TDC) in adult patients.Methods Clinical data of 36 adult patients with TDC were analyzed retrospectively.Results All the 36 patients received surgical resection of Sistrunk's procedure.One case suffered wound infection after the operation.Two cases recurred(recurrence rate:5.6％)but cured after the 2nd operation and showed no sign of recurrence during the follow up of 18 and 26 months respectively.No other complications were reported.Conclusions Etiological factors,pathological and anatomical features need to be analyzed.Surgical treatment should focus on hyoid bone and the upper area.The recurrence rate depends on total resection of cyst.

Objective:To compare the effectiveness and recurrence rate of different types of mesh or without mesh in laparoscopic hiatal hernia repair.Methods:From Jan 2016 to Mar 2022 at the three hospital 90 patients with hiatal hernia, including 26 cases without mesh, 29 cases using synthetic mesh, and 35 cases using biological mesh underwent laparoscopic hiatal hernia repair.Results:The surgical procedures was successful in all the 90 cases without conversion to open surgeny. There were no statistically significant differences in operative time, intraoperative blood loss and postoperative hospital stay among the three groups ( P>0.05), and there were statistically significant differences in hospital cost between the group without mesh and synthetic mesh and biological mesh ( P<0.05). Long-term follow-up was achieved in 87 patients, with a follow-up rate of 96.7% (87/90), and a median follow-up time of 44 months. There were no significant differences in the incidence of postoperative complications (diarrhea, dysphagia, abdominal distension, chest pain), recurrence rate of symptoms (acid reflux, heartburn) and patient satisfaction among the three groups ( P>0.05). Conclusion:In laparoscopic hiatal hernia repair, the mesh should be carefully selected according to the specific intraoperative situation for a satisfactory clinical efficacy.

More and more researches demonstrate that astrocytes display the markers of neural stem cells or progenitor cells and have the potential of neural differentiation.Thus,it is possible that astrocytes,especially overactive astrocytes,could replace injured neurons and repair the damaged function by transdifferenting and gene reprogramming.Here,we summarize recent progresses of various transcription factors and their regulation in astrocytes-to-neurons transdifferentiation.

The typical manifestations of primary aldosteronism (PA) are hypertension with or without hypokalemia, high aldosterone, and low renal level. However, PA with normal blood pressure is rare in clinical practice. This article reported the diagnosis and treatment of a patient with subclinical PA, admitted for "adrenal accidental tumor" with normal blood pressure and serum potassium. We summarized and analyzed the clinical characteristics and treatment strategies, in order to provide some reference for clinicians.

Burning mouth syndrome (BMS) is a chronic oral and facial pain disorder characterized by burning pain in the oral mucosa, with multiple pathogenic factors including psychosocial, neuropathological, endocrine, and immune factors. There is still a lack of effective treatment options that have been demonstrated to work. With the development of research on the pathogenesis and treatment of BMS, multidisciplinary comprehensive treatment has gradually been introduced and become a new trend of diagnosis and treatment. Before multidisciplinary treatment, it is necessary to go through a full and comprehensive diagnosis and analysis, select the best comprehensive treatment plan, take the diagnosis and treatment of stomatology as the basis and premise, and apply other multidisciplinary combined treatment, including the treatment of concurrent diseases, psychological interventions, correction of bad habits, etc. A combination of laser therapy and psychological intervention is a more effective treatment method among the current treatment methods, with high comfort and good acceptance by patients. If necessary, mecobalamin tablets, clonazepam α-lipoic acid and other drugs can be used to nourish nerves and provide symptomatic treatment. The comprehensive multidisciplinary treatment of BMS is expected to become a new trend and provide a new strategy for improving the therapeutic effect.
