Hypothyroidism is one of the most common endocrine disorders in childbearing or pregnant women.Gestational hypothyroidism can increase the incidence rate of the variety of pregnancy complications and adverse pregnancy outcome.It also can make adverse effects on the fetus and neonate,such as death,placental abruption,fetal malformation,intrauterine growth retardation and preterm,low birth weight,neonatal respiratory distress syndrome,it can also cause abnormal thyroid function of neonate,severely can cause nerve,mental,physical and mental developmental abnormalities and even death.Therefore,it is recommended that childbearing women who are at high risk for pregnancy should strengthen to monitor pregnancy thyroid function and treat as soon as possible in order to reduce the adverse effects on offspring.

Pancreatic cancer has a strong ability of invasive and metastasis,and the mechanism is still not completely clear.It has been demonstrated that aberrant expression of microRNAs(miRNA) is closely associated with the occurrence,development and metastasis of pancreatic cancer.The reveal of miRNA mechanism related to the metastasis of pancreatic cancer would provide a new approach to the treatment of pancreatic cancer.

This review discusses several strategies that have been employed to enhance the regenerative effectiveness of artificial nerve guidance channels. These strategies include the use of scaffolds, the integration of contact-mediated cues within the tubular construct, and incorporation or delivery of exogenous growth factors into the conduit lumen uniformly or in a gradient form. Animal and clinical studies are reviewed to explain some of the ideas involved in developing a guidance channel of the future.

Magnetic resonance diffusion tensor imaging (DTI) has been established as the primary imaging modality for non-invasive characterization of the direction-dependent motion of water molecules in the living tissue. DTI provides each image voxel with a 3x3 tensor matrix that can be processed to probe tissue microstructure and microarchitecture. In this paper, the imaging principle and diffusion tensor calculation are introduced. Examples are given to describe image-processing techniques for DTI visualization, fiber tracking, and applications to central nervous system.

Objective To investigate the situation of college students using cell phones,and explore the relationship between College Students' cell phones addiction and self-control and the regulation effect of academic performance.Methods Using the entity questionnaire survey and the online questionnaire survey to research the situation of the college students' intelligent cell phones use and self control and the regulation effect of academic performance.Results The smartphone was very popular among college students,with 84.9％ of college students using smartphones in the two surveys,and the smartphone addiction was about 10.6％.Smartphone addicts of college students related with origin of student (t=2.31,P=0.022),and had no correlation with gender (t=-0.46,P=0.647),and major (t=1.77,P=0.079).Students' phone addiction and self-control were positively correlated (r=0.506,P＜0.01).The academic record ranking was regulated by self-control and college smart-phone using.Conclusion Cell phones are widely used among college students.Self-control positively related with cell phones and cell phone addiction,and the academic record ranking regulates the strength of relationship between the cell phones using and self control.

Objective To study the interaction between human microRNA ( miRNA) and 5′trailer regions of Ebola virus genome from the perspective of bioinformatics so as to facilitate prevention and treatment of Ebola virus .Method The miRNA target prediction software Pita and RNAhybrid were used to predict the human miRNAs which could bind the 5′trailer regions of Ebola virus genomes before the miRNAs were annotated by g:Profiler web server .Results and Conclusion There may be complex interactions between human miRNAs and the 5′trailer regions of Ebola virus .Previous reports about the interaction between host miRNA and 5′trailer region of virus genome suggest that the interaction between human miRNA and 5′trailer region of Ebola virus may have effect on replication of Ebola virus and human cells .This work may provide new ideas on prevention and treatment of Ebola virus .

Objective To analyze human operational reliability,and to provide suggestions for design of controllers in spacecraft cabin.Method Twenty-two male subjects participated in 924 person-times of experiments.The experiments were divided into 6 groups to study the effect of space suit glove,time interval and task on human operational reliability in spacecraft cabin.Result 1)Task had obvious effects on operational reliability and time(P

Objective To summarize the clinical experience of endovascular intervention for intra-cranial aneurysms, especially in the respect of the technique and management of intra-operative complications. Method The clinical data of 60 patients with intra-cranial aneurysms treated with endovascular intervention in the past 3 years were analyzed. The relevant literature especially with regard to the practical technique described was reviewed so as to potentiall minimize and properly manage the intra-operative complications. Results A total of 69 sacciform aneurysms and one dissecting aneurysm located at left vertebral artery (VA) were detected by using digital subtraction angiography (DSA) in 60 patients. There were 65 saccular aneurysms obliterated with constructive approach, and five of them treated with stent-assisted technique and four of them treated with ballon-assisted technique. The VA dissecting aneurysm was obliterated with coils by deconstructive approach with complete occlusion of its parent vessel. There were a total of 53 complete occlusions of aneurysms accounted for 76.81% of 69 sacciform aneurysms in 51 patients ( 85 % ) and eight subtotal occlusion of aneurysms (95 % ～ 99 % occlusion) accounted for 13.56% of total sacciform aneurysms in five patients (8.47%) and four incomplete occlusion of aneurysms ( ＜ 95% occlusion) accounted for 6.78% of total sacciform aneurysms in three patients (5.08%), and one was failure in operation. The rupture of aneurysms occurred during operation in4 patients (6.78%). Two senile patients suffered from intra-opeartive symptomatic thromboembolisn. One patient had stent shifting and spring coil dislocated and moved into the M3 segment of the ipsilateral MCA. Vasospasm occurred in 15 patients during operation, and most of them received endovascular intervention 3 days after the initial ictus. The rate of good recovery was 93.3% at discharge from hospital (the modified Rankin Scales, mRS＜ 2). There were 55 patients followed up for up 24 months after discharge, and excellent recovery rate was found in 51 patients ( mRS ＜ 2), and 3 died.During the follow-up period, no aneurismal recanalization or rupture was noticed in all patients. Conclusions The endovascular intervention is a safe and effective approach to the intra = cranial aneurysms. Advances in the skill of technique and proper management will decrease the complications during operation and improve the prognosis of patients.

OBJECTIVE: To observe the therapeutic effects of the conventional therapy plus Melitracen and Flupentixol in the treatment of functional dyspepsia(FD).METHODS: 320 FD cases were divided into gastrointestinal dyskinesis type(Type A,n=120 cases),ulceration type(Type B,n=100 cases),and nonspecific type(Type C,n=100 cases) based on their clinical symptoms.Patients of different clinical types were randomly assigned to receive conventional therapy alone or in combination with Melitracen and Flupentixol for 4 weeks.The curative effects were observed using gastrointestinal symptom rating scale(GSRS) and the total effective rate were computed.RESULTS: After treatment,the GSRS score of 3 different clinical types of FD in the combination therapy group versus the conventional therapy alone were 1.53?1.68 vs.3.10?1.78,2.02?1.63 vs.3.48?1.80 and 3.46?2.95 vs.5.18?3.21 respectively(P
