Cultured human embryonal thymus graft was performed on 80 patients with allergic rhinitis to observe the immune function of the patients and the treatment efficiency. The thymus from the fetus of intermediate abortion was cultured for 7 to 10 days. The T cell subsets and serum antigen special IgE(sas IgE) level of the patients were determined before and after the thymus transplantation. The gross treatment efficiency is up to 92.4% among the trial patients after graft for 3 years and CD8 positive cells were increased with a significantly statistical difference (P＜0.01), and sas IgE level was much lower than before thymus transplantation (P＜0.01). It was concluded that the thymus transplantation might regulate the immune function of the patients with allergic rhinitis, including increases in the number and the function of Ts cells, and a decrease of IgE level.

Recent research has revealed that scorpion venom contains short-chain peptides with the specificity on K+or C1-channels, in addition to the knowledge of many kinds of long-chain peptides with the specificity on Na+ channels. According to the similarity of molecular structure and/or function, they have been classified into several groups. These short-chain scorpion peptides are playing more and more important role in studying the structure and function of K+ or C1- channels. The advance of structure and function of short-chain scorpion peptides in recent years was briefly introduced.

Objective:To analyze the clinical features of oral emergency patients in general health, and to guide the oral emergency patients in the treatment, and prevention of accidents.Methods:The retro-spective study was performed on the day visits to the emergency department in Peking University School and Hospital of Stomatology from February to November 2013.The basic information of the newly diag-nosed adult, their overall health status, American society of anesthesiologists(ASA) classification and oral diagnosis information were analyzed and summarized.Results:The cardiovascular and cerebrovascular diseases(6.4%), hypertension(13.4%), endocrine system diseases(4.2%)were most common in the patients.With the increase of age, the associated systemic diseases had increased in number and in ASA classification.Periapical disease ( 24.6%) , dental pulp disease ( 24.4%) , and periodontal disease (18.0%) accounted for about 2/3.Conclusion:The general health status of patients with oral emergen-cy worsened with the increase of age.Oral surgeons should make risk assessment before treatment.ASA classification system can help doctors predict the patient risk, take corresponding measures in advance, and help to reduce the occurrence of accidents.

The initiation and development of gastric cancer is due to the effects from both external and internal factors.Recent researches show that external environment factors regulate and control the key genes expression during the process of cell's growth and development through epigenetic modification such as DNA methylation or demethylation,histone modification and small RNA,thus playing an important role in gastric cancer's occurrence and development.

Gastrointestinal benign stricture is one of common diseases in clinics , endoscopic dilation is its preferred treatment . However , for the dilation ineffective refractory strictures , it represents a difficult management problem given the limited therapeutic in-terventions available .Mitomycin-C is an antibiotic which has the dual role of anti-tumor and anti-proliferation.As an anti-proliferative drug, it was first applied in the field of ophthalmology .Local auxiliary application of MMC can be a feasible and safe measurement to improve the efficacy of refractory esophageal strictures .The aim of this study is to perform a systematic review which employs mitomycin C in the treatment of refractory esophageal strictures caused by corrosion , endoscopic submucosal dissection , esophageal atresia repara-tion and radiotherapy .

Portal vein thrombosis (PVT) refers to thrombosis in the main portal vein and portal vein branches and is an important complication of liver cirrhosis.PVT can aggravate portal hypertension,increase the risk of bleeding,and lead to acute ischemic necrosis of the small intestine in case of shedding or retrograde movement.This article focuses on the new points of view on the mechanisms and treatment of PVT in cirrhotic patients and points out that treatment regimen should be selected based on patients'overall conditions.
