AIM: To investigate therapeutic effects of combination therapy for neovascular glaucoma ( NVG) .
METHODS: This retrospective study comprised 34 eyes of 34 patients who suffered from NVG. All patients were assigned to group A, B, C and D according to the different combination therapies. Group A ( 11 eyes of 11 patients ) was treated with intravitreal injection of ranibizumab and panretinal photocoagulation ( PRP ) . Group B ( 10 eyes of 10 patients ) was treated with transcleral cyclophotocoagulation and PRP. Group C ( 6 eyes of 6 patients) was treated with 3 therapies together. Group D (7 eyes of 7 patients) was treated with 810nm transcleral cyclophotocoagulation and soft gas-permeable contact lenses. All the patients were followed-up for 1a. The best- corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) were recorded and analyzed prior to operation and 1, 4wk, 6 and 12mo after operation.
RESULTS: All the post treatment IOP decreased significantly ( P<0. 05 ) from the values before therapy, and the IOP values after 4wk, 6, 12mo were not significantly different ( P > 0. 05 ) in statistics. Most patients' IOP can be controlled below 23mmHg after combination therapy. The visual acuity in group A after 1, 4wk, 6mo compared with those before treatment was significantly increased ( P<0. 05 ) in statistics and other groups did not significantly change before and after treatment (P>0. 05). Anterior chamber bleeding occurred to 2 cases after 1wk of transcleral cyclophotocoagulation. No other ocular or systemic adverse events were found during the follow-up duration.
CONCLUSION: After the combination of intraocular injection of the anti - VEGF drugs, 810nm laser cyclophotocoagulation and PRP, most patients with NVG disease can be effectively treated, can effectively control IOP, and retain part of the visual function, significantly improve the quality of life. In the short - term, combination therapy is safe and effective for NVG, which provides us an available strategy to conquer NVG by simply programmable operation and less suffering.

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.

Mitogen-activated protein kinases (MAPKs) are important kinases involved in the intracellular signaling transduction in mammalian. There are three major MAPK pathways: ERK/MAPK,JNK/SAPK and P38 MAPK. Current studies indicate that all of them play significant roles in the processing of pain especially in the development and maintenance of pathological pain. This review will focus on in the study of MAPK in pain modulation. The further insights into its mechanisms may highlight a nice prospect for the therapies of painful diseases.
