ObjectiveTo compare the effects of topical application of Modified Sanhuang Powder （加味三黄散， MSP） combined with cold compression versus cold compression alone on swelling and pain after knee arthroscopy through a retrospective cohort study. MethodsMedical records of 134 patients with knee arthroscopy-induced knee swelling and pain were divided into non-exposure group （51 cases） and exposure group （83 cases） based on whether they used MSP for external application after surgery. The non-exposure group received simple cold compression therapy in addition to functional exercise and routine treatment after surgery， while the exposure group received topical MSP on the basis of what were given in the non-exposure group. The Visual Analog Scale （VAS） scores were compared between the two groups before and 7 days after treatment， and knee swelling measurements were taken before and 3， 5， and 7 days after treatment. The clinical effective rate was compared between the two groups. ResultsThe VAS scores in both groups were lower after treatment （P＜0.05）， and the exposure group had lower scores than the non-exposure group （P＜0.05）. On the 3rd， 5th， and 7th days of treatment， the scores on swelling at 2 cm above the superior pole of the patella， at the midline of the patella， and 5 cm below the inferior pole of the patella significantly decreased after treatment in both groups （P＜0.05）， and the exposure group had lower scores than the non-exposure group （P＜0.05）. The total clinical effective rate in the exposure group was 91.56% （76/83）， which was higher than 78.43% （40/51） in the non-exposure group （P＜0.05）. ConclusionTopical application of MSP combined with cold compression is effective in relieving postoperative swelling and pain after knee arthroscopy and is superior to cold compress alone.

We report a complete genomic sequence of rare isolates (minor genotype) of the SARS-CoV from SARS patients in Guangdong, China, where the first few cases emerged. The most striking discovery from the isolate is an extra 29-nucleotide sequence located at the nucleotide positions between 27,863 and 27,864 (referred to the complete sequence of BJ01) within an overlapped region composed of BGI-PUP5 (BGI-postulated uncharacterized protein 5) and BGI-PUP6 upstream of the N (nucleocapsid) protein. The discovery of this minor genotype, GD-Ins29, suggests a significant genetic event and differentiates it from the previously reported genotype, the dominant form among all sequenced SARS-CoV isolates. A 17-nt segment of this extra sequence is identical to a segment of the same size in two human mRNA sequences that may interfere with viral replication and transcription in the cytosol of the infected cells. It provides a new avenue for the exploration of the virus-host interaction in viral evolution, host pathogenesis, and vaccine development.
