Objective　To study the clinical manifestation of small bowel tumors and the prognostic factors. Methods　Retrospective analysis of the clinical data were made on 42 cases of primary small bowel tumors (except periampullary tumors) admitted to our hospital from 1974 to 1999. Results　In this series, there were 6 cases of benign small bowel tumors, 5 of them were leiomyoma and 1 adenoma. Of the 36 cases of malignant 　tumors, there were malignant lyphoma in 17 cases (47.2%), adenocarcinoma in 11 (30.6%),　 leiomyosarcoma in 6(16.7%), carcinoid tumor in 1 (2.8%) and neurofibrosarcoma in 1 (2.8%). There was no characteristic clinical sign in small bowel tumors; endoscopy and barium series were the main diagnostic methods. About 50 per cent of patients with malignancy had metastasis, and only 18 cases (50%) received radical resection. Follow-up were available on 36 cases. The overall 5-year survival rate in the patients with malignant small bowel tumors was 47.3%. Multivariate analysis showed that metastasis and diameter of tumors were the main prognostic factors of the 5-year survival. Conclusions　Early diagnosis and early treatment play the key roles in improving the prognosis of malignant small bowel tumors. Radical resection should be taken if no metastasis is found.

Aim To establish depression rat model with kidney-yang deficiency and evaluate the related parameters.Methods A total of 24 adult SD rats were divided into control group,mod-el group and self-healing group by body weight.Model group and self-healing group were injected hydrocortisone for 21 days, meanwhile the control group was injected sodium chloride.After modeling,the related indexs detection were taken out:open-field test,sucrose preference test and forced swim test.Then the orbital blood was taken to detect 5-HT,DA and NE by LC-MS/MS.And liver,kidney,spleen,thymus,adrenal gland,testis and epididymis were taken to calculate organ index.Results Compared with the control group,model rats displayed depres-sion and kidney yang deficiency syndrome such as dry hairs, chills,back arched and so on. Correspondingly, the body weight increased slowly.Immobility in FST was significantly in-creased. Sucrose preference, horizontal scores and vertical scores was significantly decreased.Organ index decreased in liv-er,kidney,spleen,adrenal,testis and epididymis.The level of 5-HT and NE was significantly high.Compared with the model group,5-HT,NE and DA were significantly reduced,5-HT and DA were even lower than those of the control group.Conclusion Depression rat model with kidney-yang deficiency could be in-duced by continuous injection of hydrocortisone.

Objective: To explore the relationship between serum levels of immunoglobulin E (IgE) and calciifc aortic valve disease (CAVD) in relevant patients.
Methods: A total of 394 patients were enrolled in our study. Based on echocardiography presentation, the patients were divided into 2 groups: CAVD group,n=169 and Non-CAVD group,n=225. Serum levels of IgE were examined by chemiluminescence method. The IgE levels were compared between 2 groups and the relationship between serum IgE level and CAVD was analyzed.
Results: Serum levels of IgE in CAVD group was significantly higher than Non-CAVD group 113.30 IU/ml vs 63.76 IU/ml (P<0.05); multivariate logistic regression analysis conifrmed above difference (P<0.05) and it also indicated that the alteration of surum IgE level is obviously related to CAVD occurrence.
Conclusion: Serum IgE level is obviously increased in CAVD patients. IgE is an independent biochemical indicator of CAVD, it may play the important role in CAVD pathogenesis.

Mesenchymal stem cells(MSCs)are self-regenerating,rapidly proliferating pluripotent stem cells that depend primarily on their derived pro-angiogenic,inflammatory regulatory,and tro-phic factors to exert beneficial effects that attenu-ate deleterious inflammatory responses,reduce vascular damage,and promote tissue repair and re-generation.Obstructive sleep apnea hypoventila-tion syndrome(OSAHS)is a chronic disorder marked by oropharyngeal collapse during sleep,re-sulting in transient reduced airflow,large fluctua-tions in intrathoracic pressure,and intermittent hy-poxia and hypercapnia.OSAHS subsequently cyto-kine-mediated inflammatory cascades,oxidative stress,and ischemia,recruit MSCs from inflamed and damaged tissues through MSCs-derived of anti-inflammatory and pro-angiogenic factor activity,re-duce hypoxia,suppress inflammation,promote re-generation,and prevent fibrosis in OSAHS-injured tissues.In this paper,we will describe the patho-genesis of inflammation,oxidative stress,fibrosis and ischemia from the perspective of OSAHS,high-lighting the current research progress on MSCs-de-pendent regulation of OSAHS-related pathology.

Obstructive sleep apnea(OSA)can lead to complications in various systems and or-gans of the body.Dry eye(DE),the most common ocular surface disease in clinical practice,affects visual-related daily activities and work in varying degrees.Recent studies have revealed a potential re-lationship between OSA and DE.OSA can induce DE through a series of mechanisms such as oxidative stress,inflammation,rhythm disorder and so on,and the combination of OSA and DE may profoundly affect the sleep health,mood disorders,and quality of life of patients in a new form overall.However,there is still a lack of systematic understanding of the comorbidity of OSA and DE,resulting in insuffi-cient screening,diagnosis and treatment of OSA related DE in clinical practice.This paper provided a review of the relationship between OSA and DE to raise awareness among clinicians of the diagnosis and management of DE during OSA treatment.

Objective:To explore the effects of bridge in, objective, pre-assessment, participatory learning, post-assessment and summary (BOPPPS) on internal nursing teaching.Methods:Totally 220 nursing students enrolled into Zhengzhou University in 2017 were selected by convenient sampling and divided into the observation group and the control group according to the teaching mode, with 110 nursing students in each group. Nursing students in the control group receiving traditional teaching, while nursing students in the control group receiving BOPPPS teaching. The effect of the two teaching modes was compared.Results:The satisfaction rate of the observation group (98.2%) was higher than that of the control group (90.0%) , and the difference was statistically significant ( P<0.05) . The assessment results of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.01) . The total score of self-evaluation of learning effect and the score of each dimension in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The BOPPPS model shows satisfying effects in internal nursing teaching, which can increase the satisfaction of students with the teaching mode, and enhance their interest in learning, academic performance, and learning evaluation.

Obstructive sleep apnea (OSA) is a common sleep disordered breathing disorder. As a major global public health problem, untreated OSA can lead to a variety of adverse health outcomes, including various cardiovascular and cerebrovascular diseases, metabolic disorders, and psychiatric disorders such as anxiety and depression. Traditional OSA therapies such as positive airway pressure (PAP), weight loss, oral appliance, upper airway surgery, and postural therapy focus on the anatomical factors of OSA. However, the pathogenesis of OSA is heterogeneous, and non-anatomical factors also play an important role in most patients. Although there is no drug with exact efficacy for the treatment of OSA, with the deepening understanding of the pathophysiological mechanism of OSA, more and more clinical studies are devoted to the study of drug treatment of OSA and its complications, and a series of results have been achieved. The following is a review of the relevant studies on drug treatment of OSA in recent years, hoping to provide literature support and theoretical basis for future research on drug treatment of OSA.

Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible and typical chronic fibrotic lung disease. In recent years, significant progress has been made in the pathophysiology, clinical diagnosis and treatment of IPF. However, to date, there is still no cure for IPF. The second messenger cyclic adenosine monophosphate (cAMP) inhibits fibroblast proliferation or differentiation into myofibroblasts during the development of IPF. Phosphodiesterase 4 (PDE4) is a major camp-degrading enzyme in lung fibroblasts, which is up-regulated during the progression of fibrosis. PDE4 inhibitors have anti-fibrosis effects in vivo and in vitro in IPF models. In addition, PDE4 is widely involved in inflammatory processes, which are also active in the pathogenesis of IPF. Thus, PDE4 inhibition is a potential therapeutic approach for IPF. This article reviews the pathogenesis of IPF and the physiological function of PDE subtype 4 inhibitors in the treatment of IPF.
