Recurrent spontaneous abortion (RSA),which affects 1% to 5% of women of reproductive age,is difficult to treat in the clinical setting. In the investigations of immunopathogenesis,diagnosis and treatment of RSA since the late 1980s,it was found that RSA was associated with abnormal maternal local or systemic immune response,the pathogenesis of autoimmune RSA was mainly associated with antiphosphlipid antibody (APA),while that of alloimmune RSA was due to the disturbance of maternofetal immunological tolerance. Systemic etiological screening process and diagnosis systems of RSA with immune type were developed,and anticardiolipin (ACL)+? 2-GP1 combining multiple assay for effective diagnosis of RSA with immune type was initially established. According to dynamic monitoring clinical parameters before and during gestation,low-dose,short-course and individual immunosuppressive therapy and lymphocyte immunotherapy for RSA with immune type were initiated. The outcomes of the offsprings of patients with RSA were followed up,and the safety and validity of the therapies were confirmed. The research achievement leads to great progress in the diagnosis and treatment of RSA in China.

Objective To investigate the roles of transcription factor GATA-3 and T-bet at the fetal- maternal interface in the pathogenesis of unexplained recurrent spontaneous abortion(URSA).Methods The expression of GATA-3 and T-bet mRNA was examined by in situ hybridization.Decidua was obtained from 20 women with URSA and 20 normal pregnant(NP)women.Results(1)The number of GATA-3 positive cells per high power field in women with URSA(25?16)was significantly lower than those in NP women(38?16)(P

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

Flocculation of fermented broth with 1,3 -propanediol using component B of natural clarifier-Ⅱ was studied. Firstly, single factor tests and orthogonal tests were carried out. The results showed the main factors which influenced the flocculation and the optimal conditions were: pH6.0, flocculant B 0.01g/L , NaCl 0g/L, and the FR was 95.97% . The following results by filtration experiments, compared with the sample without pretreatment, indicated that the filtration speed of the flocculated sample was improved dramatically, and the weights of net and dry filter cakes were increased by 41.13% and 51.88% , respectively. Electrodialysis experiments showed that flocculation could accelerate desalting process, and could take the place of centrifugal pretreatment when it combined with the filtration.
