Objective To study the clinical effect on C-IBS treated with tegaserod and bifico combined. Methods 156 patients were randomly divided into one therapy group (group A) and two control group (group B, group C). Patients in the group A were given tegaserod and bifico therapy, while those in group B were given tegaserod therapy and group C were given bifico therapy. Results After 4 weeks' clinical treatment, the rates of remission were 94.6% in group A,7 9.1 % in group B and 54.2% in group C. There were significant statistical differences among three groups(P

Congenital heart disease is the most common birth defect.With the significant improvements of cardiac surgical techniques,the survival of newborns and infants with complex congenital heart disease(CHD) has obviously been increased.However,neurological sequelae are still common and up to 25 ％ ～50％.The most important lesion after CHD surgery is white matter(WM) injury.Recent studies show that periventricular leukomalacia disease characterized by WM injury is common in C-HD infants especially after cardiac surgery.It is previously thought to be due to the cardiopulmonary bypass and surgical operation.However,with the advances in surgery and medical diagnostic technology and development of basic research in recent years,it is discovered that WM injury in infants with CHD is a complex lesion influenced by preoperative,operating and postoperative factors.The movement disorders and the defects of attention,learning and other aspects in the late growth of these children bring a huge economic burden to the family and society,reducing the quality of the population.Therefore,exploring etiology,mechanisms and control methods of WM injury in infants with CHD becomes a hot topic in recent years,and it may also become an important direction for future research,aiming to the significant improvements in CHD children with neurodevelopmental damages.

Cryptococcus neoformans(CN) is a kind of opportunistic fungal pathogen which has a predilection for the central nervous system,resulting in devastating meningitis.The management of cryptococcal meningitis remains challenging because of its high mortality,the toxicity and uncertainty effect of antifungal therapy.In recent years,the study of the mechanism of neurotropism of CN has made a great progress.Many violence factors of this pathogen and several signal pathways of the host involved in this process have been discovered.Combination therapy with immunotherapy to regular antifungal treatment has become an important adjuvant method.The present review will concisely present current progress of pathogenesis and immunotherapy of cryptococcal meningitis.

AIM: To study the effects of chromium rutin synthesized with rutin and chromium (Ⅲ) on metabolism of blood lipid. METHODS: The effects of chromium rutin on metabolism of blood lipid were evaluated by the changes of triglyceride, cholesterol, HDL cholesterol, and LDL cholesterol in normal rats and the rats with high blood lipid. RESULTS: Chromium rutin could increase the blood chromium, decrease the concentrations of triglyceride, cholesterlo and LDL cholestelol,and increase the concentration of HDL cholesterol in normal and the rats with high blood lipid rats. CONCLUSION: Chromium rutin has an effect on the blood lipid in rats.

Objective To purify and quantify the autoantibodies against various epitopes within BP180-NC16A domain from the sera of patients with bullous pemphigoid (BP). Methods Three epitopes within BP180-NC16A domain, NC16A-1, NC16A-2 and NC16A-3, were prepared. Blood samples were obtained from 10 patients who were diagnosed as active BP by clinical, pathological and immunofluorescence examination. Autoantibodies against these epitopes were purified with affinity chromatography column from the sera of these patients with active BP, and quantified separately. The relative binding affinity of autoantibodies to NC 16A-1, NC 16A-2 and NC 16A-3 was measured using thiocyanate elution method. Results The autoantibodies against NC16A-1, NC16A-2 and NC16A-3 were successfully purified from the sera of patients. On average, the amount was 49.0±20.7 μg, 117.7±22.4 μg and 39.5±18.9 μg respectively for autoantibodies to NCI6A-1, NC16A-2 and NC16A-3 purified from a portion of serum containing about 20 mg IgG. Both the amount and binding affinity of anti-NC16A-2 autoantibody were significantly higher than those of anti-NC16A-1 and anti-NC16A-3 autoantibodies. Conclusion BP180 NC16A-2 (aa507-aa520) may be the major epitope recognized by pathogenic autoantibodies in patients with BP.

Objective To evaluate the value of Binax NOW pneumococcal antigen test for rapid diagnosis in patients with purulent meningitis.Methods Cerebrospinal fluid (CSF) were collected prospectively from 86 children who were diagnosed with purulent meningitis in the Department of Infectious Diseases at Beijing Children′s Hospital from March 2013 to March 2014 and were tested by Binax NOW method.CSF culture was considered as golden standard to evaluate the sensitivity and specificity of the Binax NOW method.Continuous variables were compared with t test, categorical variables were compared with χ2 test.Results Among 86 cases of purulent meningitis, 34 (39.5%) had positive culture and 21 (24.4%) were Streptococcus pneumonia, while 31 (36.0%) were positive by Binax NOW test.Using CSF culture as golden standard, the sensitivity and specificity of Binax NOW for diagnosis of pneumococcal meningitis were 90.5% (19/21) and 81.5% (53/65), respectively.Conclusion Binax NOW pneumoniae antigen test in CSF yields high sensitivity and specificity, which is useful in clinical application and enables prompt and adequate treatment.

With the improvement of people's living standard and changes of their lifestyle, the incidence of coronary artery disease (CAD) has increased quite significantly, which has attracted great concern. Examination methods for CAD are more and more advanced, while the cost of inspection is rising. As a traditional test, the exercise treadmill test (ETT) is convenient, safe, and cheap. ETT can be conducted in almost every hospital as it doesn't need advanced equipments. The values of some new evaluation indexes for diagnosis and prognosis of CAD are reviewed in this article.

Vascular Endothelial Growth Factor and its receptors may be the pivotal stimulants in the process of growth and metastasis of a neoplasm. They boost the genesis of the blood vessels of brain glioma. Their expression is correlated with the grading of glioma. They are ideal targets in the treatment of inhibiting the growth of the blood vessels of brain glioma.

Listeria disease (LD) is a zoonosis,caused by Listeria monocytogenes (LM),the main route of transmission is foodborne spread,can cause outbreak.Pregnant women and their fetuses or neonates,older adults,and persons with underlying conditions that impair cell-mediated immunity are at a particularly high risk of invasive listeriosis.The gastroenteritis,meningitis and bacteremia are the common clinical feature.LD in children is rare.It can cause the neonates sepsis and central nervous system infection.Because of the natural resistance to cephalosporins,the choice of antibiotics seemd more important.By this article,LM in children and benefit for clinical work was recognized.
