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.

Autofluorescence has great advantage on detecting premalignant lesions and early cancers which are not detectable by conventional white light endoscopy (WLE). In this review, the recent advances in autofluorescence for diagnosis of precancerous lesions and early cancers are presented. Varieties of endogenous fluorophores in biological tissues, the potential mechanisms of the autofluorescence differences between normal and abnormal tissues, the selection of light source and optimal excitation wavelengths, and effective algorithms for processing autofluorescence data are highlighted. Finally, the shortages and improvement directions of autofluorescence technique for the diagnosis of precancerous lesions and early cancers are briefly discussed.

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.

Antimicrobial resistance has been identified as one of the world′s most pressing public health threats.The number of antibiotic -resistant bacteria and the diversity of molecular mechanisms of resistance have in-creased sharply in recent years.The presence of antimicrobial resistance in children complicates patient management and arouses widespread concern.The use of antimicrobial agents is the single most important factor leading to the deve-lopment of resistance.New effective antimicrobial agents has been needed but has not kept pace.Antimicrobial -resis-tant infection can be prevented by immunization as well.Appropriate and judicious use of antimicrobial agents is the most important factors contributing to control resistance.Clinicians should collaborate well with microbiologist and know well about resistant bacteria and its proper antimicrobial drugs.A good application of antibiotic formulary restriction has the potential to decrease antimicrobial resistance.An antimicrobial resistance surveillance between regions and countries is urgently needed.It can help us to understand and slow antimicrobial resistance in the long run.

Objective To investigate the effect of nutrition support therapy on quality of life in patients with advanced tumors.Methods 70 patients with advanced tumors were randomly divided into the observation group and the control group,each group had 35 cases.The control group was given conservative treatment,together with the ordinary liquid,semi-liquid or diet.The observation group was given nutrition support therapy on the basis of conservative therapy.The nutrition and immune index and symptom score,quality of life were compared between the two groups.Results The nutrition,immune indexes (Alb,BMI and NK) and symptom score (malaise,anorexia,insomnia,pain) of the observation group were significantly improved(t =7.92,6.98,5.56,7.41,6.47,5.61,4.52,all P ＜ 0.05),which were significantly better than those of the control group(t =4.42,4.10,4.03,6.42,5.60,4.83,4.23,all P ＜0.05).The physical function,role function,emotional function,cognitive function score and total score of the observation group were significantly higher than those of the control group,the differences were statistically significant (t =8.12,6.08,5.12,4.78,4.32,all P ＜ 0.05).Conclusion Nutrition support therapy can improve the nutritional status of cancer patients in advanced stage,relieve symptoms,improve immune function and quality of life,which is worthy of clinical application.
