In this paper, the advance of polymeric materials applied in the development of traditional Chinese medicine (TCM) and natural products was reviewed. Especially the research progresses in use of the polymeric membranes, polymeric flocculating agents, polymeric sorbents and polymeric drug delivery system (DDS) in the separation and preparation of herb and TCM were discussed in details. In addition, the future develorment of polymeric materials in TCM preparation was also discussed.

Proteomics is an emerging discipline and has been widely used in a variety of fields despite of having very short history in comparison with other disciplines. In Chongqing Medical Univer-sity, the course contents were adjusted to fulfill the most effective integration of proteomics research with postgraduate training program for medical university. Diverse teaching was advocated here and af-ter-school communications were greatly encouraged in teaching. Traditional multimedia teaching plat-form remained the main teaching way and students were organized to visit the research platform as supplementing teaching way. The overall quality and effectiveness of teaching were effectively improved by successful implementation of the above initiatives.

Objective To evaluate the treatment of aneurysms rupture during endovascular embolization.Methods Nine aneurysms ruptured during the embolization and were treated with endovascular embolization.The reasons of aneurysms rupture during embolization,the prevention and the first aid after aneurysms rupture were analysed.Results Seven patients recovered and 2 died.Conclusions The optimal treatment of aneurysms rupture during endovascular embolization is effective,(J Intervent Radiol,2007,16: 132-134)

Firstly discovered in 1980s,human immunodeficiency virus (HIV) continues to affect more and more people.However,there is no effective drug available for the therapy of HIV infection.Betulinic acid existing in various medicinal herbs and fruits exhibits multiple biological effects,especially its outstanding anti-HIV activity,which has drawn the attentions of many pharmacists.Among the derivatives of betulinic acid,some compounds exhibited inhibitory activities at the nanomolar concentration,and have entered phase Ⅱ clinical trials.This paper summarizes the current investigations on the anti-HIV activity of betulinic acid analogues,and provides valuable data for subsequent researches.

The objective of this study was to analyze the relationship between some chemokines and the pathogenesis of GVHD and to find some biomarkers with diagnostic significance through observing and comparing the changes of some chemokine levels in samples from patients with or without aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT). 26 plasma samples were obtained from 26 patients undergoing allo-HSCT at various time points after transplantation, of which 13 samples from patients with aGVHD were served as investigating group and 13 samples from patients without GVHD after Allo-HSCT were used as control group. The patient characteristics between the two groups were compared, the levels of 40 chemokines in these samples were detected by ELISA, the changes of chemokine levels in samples of 2 groups were analyzed by means of significance analysis microarray (SAM), clustering method and c-test. The results showed that there were significant differences in levels of 6 chemokines including HCC-1, MIF, IP-10, ITAC, TARC and NAP-2 between 2 groups, in which the level of MIF in plasma samples after HSCT was the highest, the difference of TARC level between 2 groups was over 10-fold. It is concluded that the level changes of chemokines mentioned above can be used as a indicator of GVHD presence, but their pathogenetic role in occurrence of aGVHD remains to be determined.

OBJECTIVETo study the therapeutic effects of azithromycin in treatment of congenital toxoplasmosis in children.

METHODSDefinite diagnosis of congenital toxoplasmosis was made on the basis of clinical manifestation combined with one or more positive results of the following laboratory tests and excluded other congenital infectious diseases: toxoplasma DNA (TOX-DNA), circulating toxoplasma antigen (TOX-CAG), and toxoplasma IgM antibody (TOX-IgM). All the patients were given oral azithromycin 10 mg/(kg.d) for 6 days followed by 8 days without medication (one course of treatment), and the regimen was persisted for 2 months and then another 2-month treatment was given at a 1-month interval. The authors continued to provide further treatment according to the state of the illness at one month interval. The patients received 2 to 8 (average 5) courses of treatment. The patients were followed-up for 2.5 to 5 (average 4) years.

RESULTSThe treatment was effective in all the patients and the patient's condition was improved. The authors repeated in 12 cases the four tests for toxoplasma (TOX-DNA, TOX-CAG, TOX-IgM, and TOX-IgG) 9 months to one and a half years after treatment. In 10 cases all these tests showed negative results, in 2 cases TOX-IgG was positive and in the other 4 cases symptoms disappeared.

CONCLUSIONThe results of the study showed that oral azithromycin had significant therapeutic effects with little side effect and was well tolerated. Azithromycin may become an alternative therapy in treatment of congenital Toxoplasma gondii infection in children.

Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare autosomal recessive disorder. This paper reports three cases of SSADH deficiency in infants. The infants developed the symptoms including developmental delay, intellectual disability, hypotonia, hyporeflexia and seizures. The electroencephalogram (EEG) showed background slowing and focal spike discharges in all of 3 patients. Head magnetic resonance imaging (MRI) demonstrated abnormalities in 2 patients, including basal ganglia damage and increased T2-weighted signal in bilateral cerebral peduncles. Urinary organic acid analysis with gas chromatography-mass spectrometry (GC-MS) revealed increased levels of 4-hydroxybutyrate (GHB) in 3 patients. SSADH deficiency was definitely diagnosed based on the clinical manifestations and the results of urinary organic acid analysis in the 3 children. It was concluded that early urine organic acid analysis is essential for children presenting with mental retardation, neuropsychiatric disturbance or epilepsy of unknown etiology.
