[Effect of rehabilitation robot rehabilitation training synchronizing acupuncture exercise therapy on postoperative rehabilitation with hip fracture].

Objective: To compare the therapeutic effect between rehabilitation robot rehabilitation training synchronizing acupuncture exercise therapy and simple acupuncture exercise therapy on lower limb function and life activity ability for postoperative patients with hip fracture.

Methods: A total of 50 elderly postoperative patients with hip fracture were randomly divided into an observation group and a control group, 25 cases in each group. Both groups were treated with acupuncture at hip three points of the affected side and lateral line 1 of vertex, anterior oblique parietotemporal line of the healthy side, hip three needles were retained for 30 min.

Carboxylated graphene oxide/polyvinyl chloride as solid-phase extraction sorbent combined with ion chromatography for the determination of sulfonamides in cosmetics.

A carboxylated graphene oxide/polyvinyl chloride (CGO/PVC) material was prepared as a sorbent for the selective extraction of sulphonamides from complex sample. After being dispersed in buffer solution, sample was transferred into the prefabricated solid-phase extraction (SPE) column, which integrated extraction and cleanup into one single-step. A multi-response optimization based on the Box-Behnken design was used to optimize factors affecting extraction efficiency.
