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.

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.

Objective To evaluate the possibility of using preoperative conventional lung function tests and impulse oscilloresistometry system (IOS) to predict the development of postoperative respiratory failure after radical lung cancer surgery in patients with poor pulmonary function. Methods Fifty-two male patients with lung cancer between 51-63 yrs undergoing radical lung cancer surgery were included in this study. Preoperative pulmonary function was assessed by conventional lung function tests ( FEV1.0 , VC, MVV) and impulse oscilloresistometry system (IOS) (peripheral airway resistance R5-R20; elastic resistance ( X5 ) and Fres. Postoperative respiratory failure was defined as short of breath (SOB) , cyanosis, SpO2 45 mm Hg.Results Nine patients developed postoperative respiratory failure (17.3%). There was significant difference in FEV1.0 , R5-R20, X5 and Fres between patients who developed postoperative respiratory failure and those who did not. Logistic regression analysis showed that Fres is an independent factor predicting respiratory failure. Conclusion Fres is an important parameter of impulse oscilloresistometry system (IOS) for prediction of postoperative respiratory failure after lung cancer surgery in patients with poor pulmonary function.
