Dead-in-bed syndrome (DBS) is a rare but devastating sudden death condition that mainly affects young patients with type 1 diabetes.Its mechanism is quite complicated and may involve multiple factors.Acute onset of recurrent and severe nocturnal hypoglycemia,abnormal cardiac repolarization,genetic factors,and obstructive sleep apnea may all contribute to ventricular arrhythmias and even sudden death.The future research plans include elucidating and understanding the underlying mechanisms and triggers for DBS,developing a risk stratification system,using real-time continuous glucose monitoring system to detect severe nocturnal hypoglycemia,and initiating appropriate therapeutic interventions to uhimately prevent the tragedy.

Objective To reveal the research focus of schistosomiasis in China through analyzing highly cited schistosomiasis related papers in journals from 2005 to 2012,so as to provide the information for formulating the plan of selecting topics of the edi-tors. Methods The published articles related to schistosomiasis in CNKI from 2005 to 2012 were collected,the citation frequen-cy of the papers was calculated according to formula,and the highly cited papers were selected according to the citation frequency. Then the information of highly cited papers including the published time,type,author and author affiliation,citation frequency, journal,grant and research item,research status and development tendency were analyzed. Results A total of 3 639 published papers related to schistosomiasis were searched and 343 papers(the citation frequency≥8)were selected as highly cited papers, and Chinese Journal of Schistosomiasis Control shared 45.19%of them. Among these papers,original articles,reviews and special reports occupied 44.90%,12.54%and 6.12%,respectively. The first authors of these papers were mainly from centers for disease control and prevention(CDCs)(17.33%),research institutions(22.67%)and colleges/universities(36.00%). Totally 50.44%of the articles received financial supports from research funds/foundations,and most of them were national or provincial funds. The research hotspots focused on epidemiology and prevention,epidemic situation analysis,vaccine,immunologic diagnosis,pharma-ceutical research,immunity and infection. Conclusions The highly cited papers related to schistosomiasis are mainly from CDCs,institutions and colleges/universities.

OBJECTIVE:To explore security of interstitial chemotherapy by implanting 5-fluorouracil sustained-release reagent into interstitial tissues of oesophageal tumor tissue and tumor peripheral tissue under orthoptic endoscope. METHODS:Relative articles were retrieved from Pubmed database from January 1988 to December 2008 and CNKI database from January 2000 to December 2008. Inclusion criteria:articles which were related to 5-fluorouracil sustained-release reagent for the treatment of esophageal carcinoma were included;Exclusion criteria:Duplicated articles were excluded. A total of 29 patients with grade Ⅲ-Ⅳ esophageal carcinoma who received implantation of 5-fluorouracil sustained-release reagent under orthoptic endoscope were collected from Department of Oncology,Shenyang Red Cross Hospital from March 2001 to December 2007. There were 22 males and 7 females,aging 51-82 years and mean age of 60.2 years. 5-fluorouracil sustained-release particles were implanted into tumor interstitial tissue under orthoptic endoscope. 800 mg 5-fluorouracil sustained-release particles were gradually implanted for 3-5 particles each time. RESULTS:Implantation of 5-fluorouracil sustained-release reagent has been reported to safely and effectively treat esophageal carcinoma. Clinical results indicated complete remission(n=3) ,partial remission(n=16) ,stable pathogenetic condition(n=6) ,and no remission(n=4) . Body mass increased in 21 patients(72.4%) ,and average effectiveness level was 70.9%. Symptoms including hemorrhage,light descent of leukocyte,light malignancy,diarrhea but excluding functional disorder of liver and kidney were found. Easement of pain in 22 patients was 75.8%,and discontinuing analgesics accounted for 50%(P

Currently,tracheal stents used in clinic include silicone,dynamic and metal types.The metal stents contain Ni-Ti memory alloy,stainless steel,and coating stents,which are cylinder and network structured.These stents are more expensive than silicone stents.The internal stents,mainly metal stents,have been used recently in clinic to treat tracheal stenosis.Tracheal stenting methods are divided into bronchofibroscope and hard lens implantation.Both tracheal and esophageal stent implantations are invasive treatment.However,tracheal stent implantation is different from esophageal stent implantation.As patients with airway obstruction are always complicated by dyspnea and hypoxemia,even respiratory failure,which increases risk and difficulty of stent implantation.During tracheal stent implantation,the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia.Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea,leading to postoperative hemoptysis.Stent dislocation is mainly caused by inappropriate selection of stent,inappropriate implantation position or severe cough.Carcinoma tissue growing along stent lumens can induce re-obstruction in stent,resulting in atelectasis relapse.Although there are many unsolved problems and the incidence of complication is 10%-20%,tracheal stent is still a safe,effective and simple therapy for tracheal stenosis.Prevention and treatment of tracheal stenosis following stent implantation and development of novel stents with better effect and fewer side effects is future study focus.

Based on hematological laboratory case study,we discussed the importance of cultivation of stuedents’medical communication competence in the process of laboratory medicine teaching and put forward several suggestions for the cultivation of the students’medical communication competence.

Objective To investigate the pathogenistic, clinical and pathologic characteristics and treatment in elder patients with thyroid carcinoma(TC). Methods The clinical and pathologic manifestation, the treatment and prognosis of forty elder patients with thyroid carcinoma were analysed. Results The incidence of TC in elder patients was 14.2% in all of the thyroid carcinomas in the same period. The clinical course was longer and the neoplasm was bigger. A majority of the pathology was follicular adenocarcinoma(35%), followed by adenocarcinoma, undifferentiated carcinoma and pipallary adenocarcinoma. Surgerical management was the primary therapy. 17 cases underwent redical thyroidectomy with neck dissection, 13 total thyroidectomy or subtotal thyroidectomy, 4 palliative resection. Isotopic or radiotherapy as an adjuvant therapy was done if necessary. Five year survival rat was 52.0%, mortality was 45.0% in follow up period. Conclusions The main causes of the poorer prognosis of elder patients with thyroid carcinoma are follows: ① the malignant degree of the tumor is higher; ② the reaction for the tumor in elder patients is duller. So it is important to pay attention to elder patients with thyroid nodule, and an operation should be done as quick as possible.

Objective To summarize perioperative care and effect of surgical treatment of total anomalous pulmonary venous connection (TAPVC) in newborns and babies within 6 months.Methods From September 2001 to May 2013,ninetytwo consecutive patients with TAPVC received surgical correction under cardiopulmonary bypass (CPB) with moderate or deep hypothermia.The anatomic subtype included supracardiac type 48,intracardiac type 36,infracardiac type 6 and mixed type 2.There were 36 newboms.Pathological diagnosis was made by echocardiogram,computerized tomography and operative findings during operation.The option of procedure was determined by findings.Respirator assisted breathing after operation and cardiac function was maintained by a variety of positive inotropic drugs,to prevent the happening of the pulmonary hypertension crisis.Results Severely low cardiac output syndrome occurred in 8 patients and they died within 24 hours after operation.The remaining cases postoperative recover smoothly and receive postoperative follow-up about 1 month to 12 years,3 cases of postoperative pulmonary vein stenosis (PPVS) occurred.Conclusion Total anomalous pulmonary venous connection should be surgical treatment as soon as possible with satisfied effect.The key of perioperative care is maintenance of left heart function,negative balance of liquid,prevention and treatment of pulmonary hypertension.
