Objective We aimed to develop a safe, comfortable and effective perineal washer, which prevent perineum wound from infection and improve the healing of perineal wound. Methods The perineal washer was made from high polymer medical material, including two metal catheters, pressing gasbag, medical yoke and dicty blow head. We divided women patients after vagina delivery with perineum wound or after caesarean section into the observation group and the control group randomly with 120 cases in each group from Janurary to October 2007. The control group was given perineal washing by routine washing pot and cotton ball with forceps. The observation group received perineal washing by perineal washer with cleaning fluid and was scrubbed by sponge brash. The elimination of wood swelling, the healing of perineum healing, the urinary infection for patients with indwelling urinary catheterization and patients comfort degree were observed in the two groups. Results Statistical difference existed between the two groups in such aspects, elimination of wound swelling wound healing urinary tract infection and patients comfort degree, P<0.05 or P<0.01. Conclusions Adoption of self designed perineal washer accompanied with sponge brush could completely delete bacteria and inflammatory secretion deep in the vagina and prevent the incidence of infection. It not only could hasten the elimination of wound swelling, alleviate the pain and wound healing, but also was easily developed and portable to use. It provided a new and effective method for perineal washing and is worth clinical application.

Objective To explore the causes of misdiagnosis through clinical data analysis of primary Sjogren syndrome ( PSS) patients misdiagnosed as primary hypothyroidism disease.Methods The clinical data of 34 cases with primary Sjogren syndrome ( pSS ) who were misdiagnosed as primary hypothyroidism were retrospectively analyzed.The misdiagnosis reason was analyzed.Results In 34 patients,a total of 14 patients with primary hypothy-roidism could not explain the clinical signs and symptoms, included dry mouth, dry eyes, recurrent parotid gland enlargement,both hands reynolds phenomenon, purpura like rash and joint pain in the lower extremities.A total of 20 patients with primary hypothyroidism could not be explained by an auxiliary examination abnormality, including ESR,IgG,IgM or IgA increased,white blood cells and platelets,low blood potassium,pulmonary CT suggest interstitial lung disease,ANA (+) (>1:40),RF(+)(>1:20).Conclusion pSS misdiagnosis for hypothyroidism is not uncommon.Department of Endocrinology physicians should pay special attention to hypothyroidism can not explain the symptoms and auxiliary examination abnormal, make the necessary differential diagnosis to reduce the misdiagnosis rate.

Idiopathic orbital inflammatory pseudotumor (IOIP) is a common ophthalmic disease that severely damages the visual acuity and countenance of the patient,its etiology and pathogenesis are unclear.Many hypotheses have been proposed,including infection,autoimmunity and neuroendocrine mechanism,etc..These hypotheses reflect certain aspects of the etiology and pathogenesis of IOIP and provide information for further understanding of the disease.The research progression in the etiology and pathogenesis of IOIP was reviewed.

In recent years,immunoglobulin G4-related disease (IgG4-related disease) has received increasingly attention in medical community as a novel clinical entity.Although its clinical manifestation varies,high serum IgG4 concentration and numerous IgG4-positive plasma c(c)ll infiltration are the common characteristics.IgG4-related disease involves many human organs,and most one is pancreas,followed by parotid gland,bile duct,liver,lung,lymph node and so on,and orbital involvement is relatively rare.Current initial research shows that there is certain association between orbital disease with IgG4,and these diseases mainly include benign lymphoepithelial lesion,idiopathic orbital inflammatory pseudotumor,Castleman ' s disease,xanthogranuloma,Rosai-Dorfman disease etc..The researching progression in the relationship between IgG4 and orbital diseases is reviewed.

Idiopathic orbital inflammatory pseudotumor (IOIP) is a common ophthalmic disease with uncertain etiology and pathogenesis.It charactarized by chronic inflammatory cell infiltration and connective tissue proliferation.At present,its clinical treatments mainly include pharmacotherapy,radiation therapy and surgery,and the primary treating drugs include glucocorticosteroids and immunosuppressive agents.The mainstay of therapy is systemic glucocorticosteroids,although there is an increasing trend toward the use of alkylating agents,antimetabolites,monoclonal antibodies and other immunosuppressive agents.The progress in clinical treatment of IOIP was reviewed.

It is of essential importance for college students to think creatively. Flexible teaching methods have been adopted during the teaching of medical writing in our university. We inspired, guided, stimulated students to develop their creative thought. The purpose of the article is to develop the creative thought of the students in medical universities.

Objective To investigate the effective nursing measures of reducing the complications of intratra-cheal suction about mechanical ventilation patients to improve airway nursing quality. Methods 80 patients with ar-tificial air passage mechanical ventilation were divided into Control group (Group one, 40 cases) and Testing group (Group two, 40 cases) randomly. In the control group, suck at regular time after injecting normal saline solution in-to the in-airway (in order to diluted the sputum). There are improvement that nursing measures in testing group. For sample, suck sputums according to demands, choose appropriate sucking sputums tube, control the deepth of sucking sputum tube, adjust the negative pressure based on the deepth of sucking sputum tube, give pure oxygen two to three minutes before and after the suction, strengthen the airway humidfication, lubricate the sucking sputum tube with chlorotetracycline eye ointment, etc. Complications of intratracheal suction were compared in two groups. Results The comparison showed that the complications have a significant statistical difference in sputum obstruction, SpO2 de-scending to 80 percent and below during suction and airway mucous membrane traumatic hemorrhage. (P < 0.01). Conclusion The improved intratracheal suction will decrease the complications obviously like sputum obstruction, SpO2 reducing to 80 percent and below during suction and airway mucous membrane traumatic hemorrhage.

Eddy current is one of the most important factors that influence image quality during the process of magnetic resonance imaging. This paper analyzes the reason that eddy current appears and introduces several methods to compensate it. A new method to adjust parameters of eddy current compensation is developed, which proves efficient to enhance image quality through XGY OPER-0.3 MRI system.

The liver X receptor(LXR) is one of the nuclear receptors related to metabolic syndrome.LXR plays an important role in the balance of cholesterol and lipid metabolism.LXR has been found to increase the utilization of glucose,decrease the insulin resistance,and simultaneously has an adverse effect in islet β cell.LXR influences fat cell differentiation and reduces expression of the obese gene then cause obesity.It also participates the development of non-alcoholic fatty liver and control the atherosclerosis.LXR is involved in inflammatory responses in macrophages and lymphocytes.The ability of LXR to integrate metabolic and inflammatory signaling makes it particularly attractive target for intervention in human metabolic diseases.In this review,we summarize the studies of LXR,clarify the LXR in the prospects for the treatment of metabolic syndrome.

Objective:To summary the experience of the treatment of the patient in perioperative period with TAPVC.Methods:24 children(Male/Female 16/8)with TAPVC corrective operation were collected from March 2007 to June 2009,which age from 10 d to 182m(16.78?37.30)m and weight from 2.8～36 kg(7.00?6.83)kg.The care and treatment were applied to all cases after surgery,which included mechanical ventilation and continually low-does inotropic agents.Results:Two cases died postoperatively of pneumorrhagia and infection complicated with multiple organ dysfunction syndrome,respectively.The period of mechanical ventilation was 3～393(72.83? 80.63)h.The complication included low cardiac output syndrome(3 cases),pnmonia(11 cases),respiratory dysfunction(13 cases), arrhythmia(5 cases)and pneumorrhagia(1 case).Six cases were re-intubated children.Conclusion:TAPVC,especially with obstrction of pulmonary venous,should be surgically correced as earlier as possible to prevent pulmonary pertention and fibrosis of pulmonary venous.Pneumonia and respiratory dysfunction are the most important reason for prolonged ventilation time and ICU stay after cardiac surgery.Therefore,optimal respiratory management and prevention of low cardiac output will be beneficial for intensive care after TAPVC corrective operation.
