Objective:To explore the application and effect of multidisciplinary collaboration in patients with tophi during perioperative period.Methods:Forty-five patients undergoing tophaceous gout surgery in our hospital from May to October 2020 were selected as the control group and treated with routine treatment.From November 2020 to April 2021, 41 patients undergoing tophaceous gout surgery in our hospital who were treated with multidisciplinary collaboration management mode were included as the intervention group. Postoperative pain, blood uric acid level, hospitalization expenses, hospitalization days and patient satisfaction were compared between the two groups.Results:After implementing the multidisciplinary integration man-agement mode, the pain score of the patients at 4 hours, 1 day and 3 days after operation was lower than that of the control group [(3.6±1.0) vs (4.1±1.0), t=2.33, P=0.022; (2.5±0.8) vs (3.0±0.6), t=3.85, P<0.001; (1.8±0.5) vs (2.2±0.7), t=3.52, P<0.001], the serum uric acid level was significantly lower than that of the control group at 1 month and 3 months after operation [(355±58) vs (3928±39), t=3.50, P=0.001; (316±48) vs (366±47), t=4.84, P<0.001], the hospitalization days and hospitalization expenses were significantly decreased [(8.90±2.48) d vs (10.62±3.96) d, t=2.44, P=0.017; (1.00±0.13) ten thousand yuan vs (1.11±0.17) ten thousand yuan, t=3.34, P=0.001], and the patient satisfaction was markedly improved (97.6% vs 82.2%, χ2=3.87, P=0.049). Conclusion:The multi-disciplinary collaboration mode in patients with tophi during perioperative period can effectively reduce the postoperative pain, improve the quality of care, promote reha-bilitation, improve the outcome, and reduce the economic burden of patients, which is worthy of popularization and being applied in clinic.

The aim of the study is to obtain an efficient expression of recombinant ubiquitin-like specific protease 1 (Ulp1) by gene engineering. We cloned the Ulp1p, active fragment (403 aa-621 aa) of Ulp1, from Saccharomyces cerevisia, and subcloned into pGEX/Rosetta (DE3) to form an expression plasmid, pGEX-Ulp1p-His6. In order to enhance the solubility of GST-Ulp1p-His6, we purified the fusion protein GST-Ulp1p-His6 by either glutathione S-transferase agarose or Ni-NTA resin chromatography, the purity was up to 98%. We utilized the protein to cleave the SUMO fusions, and the specific activity of GST-Ulp1p-His6 was 1.375 x 10(4) U/mg. This study showed that the recombinant protein GST-Ulp1p-His6 displayed high specificity and activity.

<p><b>UNLABELLED</b>BACKGROUND AND OBJECTIVE Telomerase and CYFRA21-1 may be positively expressed in malignant pleural effusion, but the sensitivity and specificity of single tumor marker were low. The aim of this study is to investigate the diagnostic value of combining determination of telomerase activity and CYFRA21-1 levels in differentiating benign from malignant pleural effusion caused by lung cancer.</p><p><b>METHODS</b>80 patients with malignant and 50 patients with benign pleural effusion were enrolled into this study. The telomerase activity in pleural effusion was tested by means of telomeric repeat amplification protocal-PCR-ELISA (TRAP-PCR-ELISA) and CYFRA21-1 levels were tested by the EIA method. All the results were analyzed by the statistical method.</p><p><b>RESULTS</b>The levels of telomerase and CYFRA21-1 in malignant pleural effusion was significantly higher than that in benign one (t = 17.252 and t = 13.951, P < 0.001). The sensitivity of telomerase activity testing for diagnosing malignant pleural effusion was 71.3%; the specificity was 86.0% and the overall accuracy was 76.9%. The sensitivity of CYFRA 21-1 testing was 60.0%, the specificity was 78.0% and the overall accuracy was 66.9%. The sensitivity of the combined testing was 90.0%, the specificity was 76.0% and the overall accuracy was 86.9%. The sensitivity and the overall accuracy of combined testing were higher than those of telomerase and CYFRA21-1 testing single (chi2 = 9.002 and chi2 = 19.201, P < 0.01; chi2 = 4.389 and chi2 = 14.647, P < 0.05).</p><p><b>CONCLUSION</b>The combined testing oftelomerase with CYFRA21-1 can increase the sensitivity and overall accuracy of differential diagnosis of benign and malignant pleural effusion diagnosis.</p>
