Objective To explore the medium-and long-term efficacy of modified approach arthroscopy in the treatment of ischial tuberosity cysts in middle-aged and elderly people.Methods Clinical data of 19 cases of ischial tuberosity cyst treated arthroscopically from January 2018 to December 2020 were retrospectively analyzed.The cyst wall was removed by using the central approach of the ischial tuberosity cyst and the 3-5 cm approach of the cyst to the outside of the buttocks.Results The operation time was 30-45 min(mean,36.2±4.8 min).The Visual Analogue Scale(VAS)scores of the pain on the 1st,7th,and 28th d after surgery were 2-6(mean,3.7±1.1),1-4(mean,1.9±0.9),and 0-1(mean,0.5±0.2),respectively.There were 18 cases of incision grade A healing and 1 case of grade B healing.The total hospitalization time was 3-6 d(mean,3.8±1.1 d).There were no complications such as incision infection and subcutaneous hematoma.The 19 cases were followed up for 40-81 months(mean,60.5±10.2 months),and 1 case had cyst recurrence at 3 months after surgery.Conclusion The modified approach arthroscopy is safe and effective in the treatment of ischial tuberosity cysts,having satisfactory medium-and long-term efficacy.

Based on Ag nanoparticles as the surface-enhanced Raman spectroscopy (SERS)-active nanostructure, the SERS of uric acid was presented in the paper. The absorption spectroscopies of uric acid and the mixture of silver colloids and uric acid were measured. The possible enhancing mechanism of the uric acid on silver colloid was speculated. The characteristic SERS bands of uric acid were tentatively assigned. The influence of absorption time and different ion on the SERS of uric acid were also discussed. The SERS spectral intensity changes linearly with the uric acid concentration, which indicated that the SERS might provide a new kind of direct and fast detecting method for the detection of uric acid. The detection limit of uric acid in silver sol is found to be 1 mg/L.
