Objective To investigate the causes and influencing factors of dead on arrival (DOA) in children.Methods The clinic data from 66 children with DOA admitted in the emergency department of Hunan Children's Hospital from Jan 2010 to Apr 2012 were analyzed retrospectively.Results All of the 66 cases had cardiac respiratory arrest when admission.Fourteen cases had arrest for 10 minutes,12 cases for 30 minutes to an hour,40 cases had no details.Forty-four (68.2％) cases were carried by parents,22(31.8％)cases were transferred by medical professionals.The main causes of DOA were severe pneumonia with respiratory failure and (or) heart failure,intracranial infection,neonatal diseases.All cases were taken to resuscitation room by triage immediately.Tracheal intubations were completed in 48 cases and intravenous access with injection of epinephrine and other resuscitative drugs were established in all cases,but all cases were dead due to breathing and heartbeat stopped for a long time.Conclusion DOA is one of the important reasons for pediatric high-risk.The key of reduction of DOA incidence and improvement of survival rate is to improve pediatric emergency medical service system,strengthen the health education for the parents,to carry out training and establish homogenization service in emergency ICU.

Objective To observe the curative effect of surgical treatment for eyelid basal cell carcinoma. Design Retrospective case series. Participants 33 cases with eyelid basal cell carcinoma. Methods 33 cases with eyelid basal cell carcinoma treated with surgery, standard excision in 17 case and Mohs micro excision in 16 cases were analyzed, postoperative appearance and function of re- eonstruetiiv eyelid, reeurence rate and survival rate were observed by follow-up survey. Main Outcome Measures Postoperative ap- pearance, function of reconstruetiiv eyelid, recurence rate and survival rate. Results After 6 month ~ 5 years follow-up survey with an average of 2.5 years, 28 of 29 cases obtained normal eyelid appearance, 1 case with lower eyelid gentle ectropium. 11 cases showed hy- perpigmentation in skin-grafting area in early stage, and became normal in half a year. Eyelid function of 29 cases were normal. Tumour relapse was seen in one case 2 years after standard resection,the cure rate was 94.12%. No tumor relapse was seen in group of mohs micro resection, the cure rate was 100%. Within five years postoperation, there was no death case caused by basal cell carcinoma re- lapse, except one dying from myocardial infarction and another dying of eerebrovaseular disease. Conclusions Operational excision is an effective approach for eyelid basal cell carcinoma. The effect of mohs micro resection is better than the one of standard resection. With dissociate skin grafting, fluctuate tarsal transmigration and dissociate skin grafting, eyelid appearance and function recover well.

18 F-FDG PET-CT has been widely used for the diagnosis,staging and assessment of therapeutic response in patients with non-small cell lung cancer (NSCLC).In particular,the technique plays an important role in the prediction of the response to therapy in patients with locally advanced NSCLC.It can dynamically observe the tumor tissue metabolism,and according to the changes of 18 F-FDG uptake by visual or quantitative analysis,before and after treatment,allow prediction of the early efficacy of locally advanced NSCLC with chemotherapy and (or) radiotherapy in clinical or sub-clinical levels.

Bone marrow stromal antigen 2 (BST-2) is a kind of host restriction factor. Since it was discovered to be responsible for the defect in virion release of HIV-1 mutants lacking the accessory gene vpu in 2008, it was thought to mainly restrict the viruses by directly tethering viral particles at the plasma membrane. Recent reports suggest that BST-2 also can inhibit the the release of HBV particles, which are budding in the intracellular vesicles, expanding the antiviral spectrum of BST-2. Futhermore, the machanism that BST-2 used to restrict HBV release in multivesicular bodies (MVBs) is similar to that used to restrict HIV at the plasma membrane. However, HBV have evolved strategies to antagonize the antiviral action of BST-2. There are two different opinions about the antagonist. One is HBV inactivated BST-2 by HBx requiring a hepatocyte-specific environment. Another thought envelope protein HBs counteract the antiviral action of BST-2. In this review, we focus on the current advances in the anti-HBV activity of BST-2.

Clinical data of 448 patients aged ≥60 years with osteoporotic hip fractures admitted in Shanghai Huashan Hospital between January 2010 and December 2014 were retrospectively analyzed.Among 448 cases,there were 143 males and 305 females;196 cases aged 80-89 years (43.8％) and 137 cases aged 70-79 years (30.6％);304 cases of femoral neck fracture (67.9％) and 144 cases of intertrochanteric femoral fracture (32.1％);the fractures caused by fall in 328 cases (73.2％) and comorbidity with hypertension and diabetes mellitus in 415 cases (92.6％).Two hundred and sixty eight patients were followed up for 2 years,among whom re-fractures occurred in 17 cases.The study indicates that health education is important for prevention of osteoporotic fractures in elderly people.

OBJECTIVE To investigate the flora distribution,enzyme producing and drug resistance of Citrobacter in our hospital,and analyzed multi drug resistance(MDR) character in order to guide the clinical medication.METHODS Totally 147 clinical isolates of Citrobacter were detected out ESBLs and AmpC ?-lactamases by three-dimensional test,MBL by the double-disk synergy test.at the same time,drug resistance to fifteen antibiotics was also detected by K-B method.RESULTS Hospital infection caused by Citrobacter.most commonly by C.freundii and then C.amalonaticus.Respiratory tract and urinary tract were prone to be infected than other sites(P0.05).The rate of ESBLs,AmpC,ESBLs+AmpC and MBL which produced by Citrobacter were 36.05% 10.20%,7.48% and 2.72%.The Citrobacter were sensitive to imipenem and meropenem,and their resistance rates to imipenem and meropenem were 4.76% and 3.40%,respectively.The resistance rate to cefoperazone/tazobactam was 23.81%.Otherwise,the resistance rate to 12 kinds of other antibiotics were all higher than 40.0%.MDR strains in the ICU ward were 81.08%,while in other wards were 53.64%,with significant difference(P

Breast cancer is one of the most common cancers.The clinical treatment of breast cancer has made great progress,but the inherent or acquired drug resistance,tumor migration and tumor infiltration,which lead to poor treatment efficiency and eventually death,are still the urgent problems to be solved.As with the occurrence and development of common tumors,the abnormal proliferation,migration and infiltration of breast tumor cells and muhidrug resistance (MDR) are closely related to the abnormal expression of specific genes in the cell.At present,many studies have found that the occurrence and development of tumor is closely related to the abnormal expression of microRNA.Therefore,in order to better understand the molecular mechanism of the occurrence and development of breast cancer,it is necessary to study the function of microRNA in breast tumor cells.In this paper,the application of microRNA in the treatment of breast cancer was reviewed,striving for providing effective ideas for the future selection of new strategies to control the development of tumors.

AIM: To identify the effect of alkylating agent N-methyl-N'- nitro-N-nitrosoguanidine (MNNG) with low concentration on JNK/SAPK and p38MAPK and the origins of JNK/SAPK and p38MAPK cascade.METHODS: p38 and JNK kinase activity were detected by immunoprecipitation and Western immunoblotting in intact and enucleated Vero cells.RESULTS: With the same experimental conditions, low concentration of MNNG inhibited JNK kinase in both intact cell and enucleated Vero cell. MNNG activated p38 kinase in intact cell while no effect on p38 kinase in enucleated cell was observed.CONCLUSION: Inhibition of JNK/SAPK by low concentration of MNNG was independ of a nuclear signal while MNNG activation of p38MAPK may depend on a nuclear signal.

Objective To evaluate the value of 3-dimensional dynamic contrast-enhanced magnetic resonance angiography (3D DCE MRA) in the diagnosis of adrenal and renal diseases.Methods 3D DCE MRA was performed on 22 patients with adrenal neoplasm,23 patients with renal neoplasm and 2 patients with stenosis of renal artery. Comparison with surgical findings or DSA was made.Results 3D DCE MRA clearly reflected the vascular anatomy,satisfied diagnostic demands.Simultaneously,The extravascular lesions were also detected.Conclusion The 3D DCE MRA is a reliable non-damaged imaging diagnostic method.
