The ocean is the treasure house by which human being live. The variety and particularity of marine creature provide people many physiological active substances, which are novel and unique in structure and effect. The recent research of marine active antitumor proteins and peptides was summarized in this article.

Isolated otolith dysfunction(iOD) involves a group of unexplained vestibular syndromes that manifest clinically as a sense of translation, tilting or floating, and blurred vision with head movement, with normal semicircular canal function but abnormal otolith function on laboratory vestibular testing. As vestibular medicine has gained widespread popularity in recent years, increasing attention has also been paid to iOD and case reports, clinical studies and diagnostic criteria have been published. However, there is no consensus document to guide the diagnosis of this disease in China. In this context, the Special Committee on Vertigo of China Medical Education Association organized a group of domestic experts in vestibular medicine and formulated this diagnostic consensus after thorough discussion based on the latest evidence in China and abroad, in order to promote the best clinical practice for iOD.

ObjectiveThe purpose of this study was to investigate the effect of health education on the recovery of insight in schizophrenic patients. MethodThe insight of patients in health education and control groups was assessed by SAUMD and BPRS bdfore and 4, 8, 12 weeksafter trentment. ResultThe recovery of insight of health education group was significantly different from control group after treatment. Theinsight scores was significantly related to major symptom, cultural level and disease course. ConclusionThe health education for schizoprenicpatients was important in recovering insight and illness and promoting patients go back to society early.

0.05). Conclusion Isthmus is an essential structure to determine the size of femoral component. The dimension of isthmus correlates fairly well with the size of femoral stem. As a measurement to choose the appropriate femoral implant in total hip arthroplasty, the isthmus-method has the similar accuracy as the common templating.

[Objective]To observe the growth pattern of oligodendrocyte precursor cells(OPCs) in the primary culture from neonatal rat cerebral cortices and study the methods of cell culture and isolation in order to obtain purified OPCs for the experiments of cell transplantation.[Method]The mixed glial cells from the cerebral cortices of 48-hour-old Sprague-Dawley(SD) rats were cultured in vitro.Until 9-10 days in vitro OPCs were isolated and purified by the shaking process and differential adhesion,and then continued OPCs culture in the defined medium.The growth pattern of OPCs in vitro was investigated by contrast phase microscopy and OPC s were further identified with the immunocytochemical techniques.[Result]The distinct stratification of OPCs and astrocytes developed around 9-10 days in primary culture.At this point,the OPCs scattered on the top of the monolayer astroctyes and the soma of most OPCs typically appeared oval or round with two or three processes.The purity of the isolated OPCs reached 95% and these OPCs further developed into the mature oligdendrocytes which were immunoreactive to the specific antigen of oligodendrocyte lineage cells,Oligo2.[Conclusion]OPCs separated from the cerebral cortices of neonatal SD rats can be maintained as immature precursor cells in culture,and OPCs are able to be purified by shaking and differential adhesion under the condition of appropriate cell stratification.

Objective To study the effects and mechanisms of major immune nutrients and to introduce the progresses of clinical applications about enteral immunonutrition.Methods The related literatures about the effects and clinical applications of enteral immunonutrition were reviewed.Results Infection rate can be reduced and the hospitalization can be shortened as a result of the improved nutritional status and immune competence of patients which can be enhanced by reasonable enteral immune nutrition.Most of the patients suffering from serious diseases can benefit from enteral immunonutrition,such as gastrointestinal cancers,post-transplantation complications,chronic liver disorders,acute pancreatitis and so on.However,as a new nutrition therapy,the clinical use of enteral immunonutrition in critically ill patients is still controversial.Conclusions Enteral immunonutrition plays an important role in the nutritional support of patients with serious diseases,such as gastrointestinal cancers,organ failures.However,much work remains to be done.

The core event of cell proliferation is DNA replication and cell division. DNA topoisomerase type Ⅱ plays an important role in this process.As a cell proliferating marker,DNA topoisomerase type Ⅱis caught great attention. The authors review the recent research of NDA topoisomerase type Ⅱ and its value evaluated as a cell proliferating marker.

Objective To study the clinical effect of Xianglian in Mixture (Mixture of Nutgrass Galingale Rhizome and Golden Thread) in treatment of premature beat accompanied anxiety disorder.Methods Totally 100 patients of premature beat accompanied anxiety disorder were randomly assigned into two groups.The 50 patients in the treatment group were treated with Xianglian Mixture and the 50 in the control group were treated with Rytmonorm and Alprazolam for 4 weeks.The TCM symptom scores,premature beats in Holter,scores of Hamilton anxiety scale (HAMA) and the therapeutic effect on all these indices of both groups were observed.Results After treatment,the TCM symptom scores,premature beats in Holter,scores of HAMA of both groups were decreased significantly (P0.05).Conclusion Xianglian Mixture can reduce premature beats and relieve anxiety as well.

Human promyelocytic leukemia HL - 60 cells labelled with 3H - inositol were treated with vincristine (VCR), it was found that the radioactivity of 3H-phosphatidyl inositol - 4-phosphate (PIP) and 3H - Phosphatidyli-nositol - 4,5 - bisphosphate(PIP2) had no obvious change, but that of 3H-phosphatidyl inositol (PI) decreased rapidly, only accounted for 38. 55%~61.01% of the control during 1~ 120 min of the treatment. It showed that VCRdid not affect the activity of PI kinase and PIP kinase, but enhanced the hydrolysis of PI of HL - 60 cells. The inhibitorty effect of VCR upon cell proliferation and DNA synthesis was observed after above biochemical changes,these results suggest that VCR may inhibit HL-60 cells proliferation by interfering the metabolism of phosphoininositides.
