This article discussed the reform of library cataloguing induced by library standardization and automation from four aspects of expansion of cataloguing scope, the change of cataloguing methods, deep revealing of literature cataloguing, and the elevation of personnel quality.

By conducting exchanges of international periodicals,the author graphically categorized publishing information of Taiwan traditional Chinese medicine periodicals,organizations,relevant websites as well as data base in order to provide readers with information from more aspects.The author wished to raise the awareness of the importance of academic communication from both sides by analyzing conditions for the future cooperation between both sides of the Taiwan Straits.This study aimed to stimulate the development of scientific research and of the cause of traditional Chinese medicine by utilizing resources.

Acute ligation of the bilateral common carotid artery and left vetebro-ar-tery resulted in an experimental incomplete cerebral ischemia in rabbits. It was consideredthat such experimental model could be used for studying the pathogenesis of brainischemia and the effect of experimtal therapy. 654-2 (anisodamine) was given at 30 and 60 min. after ischemia. The results indi-cated that: (1) The reducing rate of the cerebral blood flow in 654--2 group after ischemiawas much lower than that in control group (P

Congenital vahular aortic stenosis (AS),which refers to a congenital malformation of the aortic valve,is the most common causes of left ventricular outflow tract obstruction in chiidren.In 1983,percutaneous balloon aortic valvuloplasty (PBAV) was firstly described as the treatment for congenital AS in children.Over the past 30 years advancement in technique and equipment had radically improved the safety and outcome of balloon valvuloplasty of aortic valve.Nowadays the technique is widely regarded as the therapy of first choice for children with congenital AS.However,it is essential to make decisions about treatment and define which approach has the best chance of success for any given patient before the initial intervention,especially for the neonate with critical AS.PBAV is usually effective for acutely relieving left ventricular outflow obstruction and has excellent short term results in most childen with congenital AS.The mid-and long-trem outcome after a successful balloon dilation of congenital AS in childhood is also good,but late restenosis and valve regurgitation eventually necessitate reintervention in the majority of children,which included aortic valve replacement.PBAV was found to have a high incidence of complications and remains one of the most challenging procedures in the inttcventional therapy of congenital heart disease.Operators should not only acquire the necessary manual skills,but also have the ability to make sound clinical judgment and deal with critical events.Owing to its palliative nature of balloon dilation for congenital AS,the follow-up care of patients after procedure is quite important.

Mycoplasma pneumoniae(MP) is the smallest organism that dose not need a host cell for replication.It is one of the most common pathogens of community acquired pneumonia in children.In recent years,the incidence of pneumonia mycoplasma pneumonia increased year by year,and severe pneumonia mycoplasma pneumonia,refractory pneumonia mycoplasma pneumonia cases also increased.MP causes a variety of clinical presentations,in addition to respiratory infections,there are also many extrapulmonary manifestations.Immune response plays a very important part in pathogenesis of MP infection.This article focused on the immune aspects in pathogenesis and extends to some diagnosis and therapeutic implications.

Universal uhrasound screening in newborn has been accepted for reducing the incidence of late detected developmental dysplasia of the hip (DDH).Unfortunately, the neonatal ultrasound screening strategy has not been applied in the mainland of China, which leads to a high incidence of late-detected DDH.Before implementing the neonatal ultrasound screening strategy, the clinical screening by limited abduction is valid to early diagnose the dislocated hip joint.Additionally,it is necessary to screen all the newborn with high risk factors of DDH, such as positive family history, breech presentation and postnatal hip extended swaddling.Early screening of DDH is the common responsibility of child care doctors, including community health physician, pediatrician or pediatric orthopedist.Currently, it is imperative to build regional neonatal ultrasound screening system for DDH in the regions with tertiary pediatric orthopedic center.

One of the important missions of modern medical ethics is to strengthen the adjustment of medical ethics and advance the infiltration of medical ethics spirits to medical science to solve the basic ethical problems caused by ART.The adjustment of Medical ethics on ART are affected through ethical regulation,exampling, leading, educating etc.Medical Ethics Committee is an important form of realizing this kind of function,and it is also the evidence of the system of medical ethics. It has been an international practice to set up ethics committee in order to carry on ethics supervision for relevant medical course.The application and development in a healthy way of ART in our country is calling for the ethics committee of medical organizations to play effective role.

objective: To offer a model for reference on the operating guideline of ART Institution Ethics Committee to regulate their conducts on ethical supervision in China. Method: Generalizing the mode of committee' action out of duty according to the scientific principle in clause. Conclusion: The suggestion draft, based on committee's practical exploration of ethics, integrates the international practice and external experience for reference properly, which is overall and has stronger operating quality and can draw lessons from the meaning.

AIM: To observe the changes in platelet-activating factor(PAF) receptor binding characteristics and explore the action of PAF on formation of thrombotic core and penumbra following local cerebral ischemia.METHODS: Neuron's membrane protein was abstracted, and the local cerebral ischemia model were induced by photochemistry in tree shrews. The PAF binding sites on central neuron membrane were studied by -PAF binding assay.RESULTS: There were two different affinities of PAF receptors on tree shrew's brain cell membrane, with kD 1=( 3.61 ? 0.72 ) nmol/L and kD 2=(17 04?2 41) nmol/L, corresponding respectively to maximum number of binding sites: Bmax1=(1 457 94?168 01) pmol/g protein and Bmax2=(5 017 40?742 16) pmol/g protein. The binding sites decreased in ischemic core, penumbra and contralateral regions at 4,24 and 72 h after ischemia ( P

BACKGROUND: Relapse of acute leukemia is possibly correlated with abnormal expression of cellular adhesion molecule-1 (VCAM-1).OBJECTIVE: To observe the level of VCAM-1 in serum and bone marrow stromal cell (MSC) supernatant of patients with relapsed acute leukemia. METHODS: Samples of serum and MSC supernatant were collected from 17 patients with remission-phase and relapse-phase acute leukemia hospitalized in the Department of Hematology, the Fifth Affiliated Hospital of Sun Yat-sen University between June 2006 and March 2008. The levels of VCAM-1 were measured with ELISA in remission and relapse phases.RESULTS AND CONCLUSION: Compared with the remission phase, the VCAM-1 level of serum was significantly increased in the relapse phase (P < 0.05). At 1 and 3 weeks after in vitro culture, the VCAM-1 level in the MSC supernatant was not changed (P > 0.05), but it was significantly increased on the fourth week (P < 0.05). The results demonstrated that VCAM-1 expression of serum and MSC supernatant in the relapse phase was greater than that in the remission phase, suggesting that abnormal expression of VCAM-1 was possibly correlated with relapse of acute leukemia.
