OBJECTIVE:To provide the reference for verifying and improving the usage criteria and guidelines of compound oral contraceptives(COCs)in China. METHODS:The usage criteria and guidelines of COCs were introduced and compared issued by WHO,US and European Union(EU). RESULTS&CONCLUSIONS:WHO has established 4 standards and guidelines for COCs, i.e. Medical Eligibilitu Criteria for Contraceptive Use(MEC),Selected Practice Recommendations for Contraceptive Use(SPR), Decision-making Tool for Family Planning Clients and Providers,Family Planning:A Global Handbook for Providers. According to the specific circumstances of the user,MEC has been divided into 4 levels according to the situation of users,i.e. suitable for use,use cautiously,relative contraindication,absolute contraindication. SPR mainly describes the specific issues of how to use vari-ous contraception methods safely and effectively. The reading card mode for Decision-making Tool for Family Planning Clients and Providers can query specific methods and steps of contraceptive informed choice fast. Family Planning:A Global Handbook for Providers can provide practical guide for the family planning service providers in the first line. On the basis of WHO MEC and SPR,some projects are modified and added in the US MEC and SPR,including the classification of breast feeding,the risk grade of DVT/PE recurrence,etc. EU have formulated COCs criteria and guidelines earlier than WHO and US;the key points and specif-ic varieties of COCs are prompted and updated based on the latest evidence- based medicine,including a new assessment of the risk of thrombosis after using the COCs,the special safety tips for the use of Diane 35? and its generics. Concerning the optimal ev-idences of current COCs usage of WHO,US and EU,combined with domestic situation,our country may provide the clear and up-to-date usage criteria and guidelines of COCs for its users and medical staff.

Extracellular signal-regulated kinases 1 and 2 (ERK1/2) pathway, which was the first cell signal transduction pathway to be discovered, consisted of Ras, Raf, MEK1/2 and ERK1/2. After the activation of ERK1/2 pathway, extracellular signals can be transmitted from the cell membrane to the nucleus. It was involved in many physiological and pathological functions of cells, such as growth, proliferation, differentiation, apoptosis and etc. It was also related to the onset of many diseases, which included multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE). The activation of ERK1/2 pathway can induce the activation of astrocyte, MG, T cell and macrophage, which released a variety of inflammatory cytokines. It caused myelin damage which induced MS/EAE onset. A number of studies indicated that inhibiting ERK1/2 pathway can reduce the releasing of inflammatory cytokines and myelin damage for MS/EAE alleviation. It provided an important target for the development of MS treatment medication.

AIM: To study the effect of peach seed (semen Persicae) on gene expression of mouse with sarcoma 180 by means of DNA microarray. METHODS: DNA microarrays were made by spotting PCR products of 4096 mice cDNA noto a specially treated glass slides. The probes were prepared by labeling experimental and control group tumor tissue mRNA with Cy3 dUTP and Cy5 dUTP separately through reverse transcription. The arrays were then hybridized against the cDNA probe mixture and the fluorescent signals were scanned. The data obtained were analyzed from two repeated experiments. RESULTS: 64 genes were obtained by computer processing. CONCLUSION: These genes identified through this approach are considered as potential candidates for PSPA anti tumor effect.

Objective To study the correlation between dose-volummetrics and changes of pulmona- ry function tests(PFTs), and to study the ability of standard dose-volummetrics to predict these changes after radiotherapy. Methods Pulmonary function was measured in 39 patients with inoperable lung cancer one week before and 2-4 months after radiotherapy. The pulmonary function parameters were the forced vital ca- pacity(FVC), forced expiratory volume in ls (FEV 1.0) and diffusion capacity of carbon monoxide(DL- CO). Dose-volumrnetrics were V_(10), V_(15), V_(20), V_(25), V_(30), V_(35), V_(40), CTV_(100), CTV_(95), CTV_(90), CTV_(80), lung D_(mean), V_(eff) and NTCP. Pearson and line regression analysis was performed to determine whether the correlation exis- ted between the metrics and the changes of PFTs. Results No correlation was found between the dose- volummetrics and the changes in PFTs. Excluding patients(n=15) with pretreatment atelectasis, signifi- cant correlation was found between the dose-volummetrics (V_(20), V_(25), V_(30), V_(35), V_(40), GTV, V_(eff) and D_(mean)) and the PFTs changes(r=0.469-0.695, P≤0.05). Therefore, the re-expansion may have jesperdized the proper data to the present record. Multivariate analysis showed that V_(30) was the risk factor to affect the chan- ges of FEV 1.0 and DLCO(P=0.046、0.041). The pulmonary function of patients with V_(30)≥18% was worse than patients with V_(30)
