Base-controlled dearomative [3 + 2] cycloadditions between 3-nitro-indoles and fumaric acid amide esters.

The base-controlled dearomative [3 + 2] cycloaddition reaction between 3-nitroindoles and fumaric acid amide esters has been disclosed by using the dearomatization and aromatization strategy. Three kinds of diverse functionalized pyrrolo[2,3-b]indole derivatives were obtained respectively with excellent chemoselectivities and good diastereoselectivities using different bases.

[Manipulation of superduct, adduction, rotation for the treatment of shoulder dislocation].

OBJECTIVE: To study the mechanism and clinical effect of using the manipulatin of move, adduction, rotation method for the treatment of shoulder dislocation. METHODS: from January 2010 to March 2012,120 patients with shoulder dislocation admitted were randomly divided into treatment group and control group, 60 cases in each group. In the treatment group, there were 31 males and 29 females; In control group, there were 30 males and 30 females. In treatment group, 60 patients create their own "on the move, adduction, rotation manipulative treatment,the other 60 cases in control group used traditional restoration methods in wearing the traction treatment. The efficacy of two methods of treatment of shoulder dislocation were compared on reset process once successfully rate, the patient's level of pain (VAS). RESULTS: In treatment group, restoration once successfully were in 59 cases, improvement of the pain (VAS) values was 3.76 +/- 1.05, the results were excellent in 57 cases, good in 2, poor in 1,without concurrent fractures and nerve injury, without re-dislocation after 3 months. In control group, restoration once successfully were in 50 cases, improvement of pain (VAS) values was 5.67 +/- 1.15, the results were excellent in 45 cases, good in 7, poor in 8. The reset once successfully rate,improvement of VAS values and clinical effect in treatment group were better than that of control group. CONCLUSION: On the move, adduction, rotation method has advantages of more wearing traction with uniform force, work together to focus, saving time and effort, easy and convenient to avoid iatrogenic injury.
