Study on the application and effect of adjustable mirabilite external vest in severe acute pancreatitis / 中国实用护理杂志

Objective:To investigate the clinical effect of homemade adjustable mirabilite vest in patients with severe acute pancreatitis and supply reference for clinical nursing.Methods:This was a randomized controlled study. One hundred patients with acute severe pancreatitis admitted to Putuo Hospital, Shanghai University of Traditional Chinese Medicine from January 2021 to June 2022 were selected, and were divided into the pocket group and the vest group according to the order of admission with 50 cases in each group. The pocket group used traditional mirabilite bag for external application, the vest group used adjustable mirabilite vest for external application. The other treatment measures were the same for both two group. The comfort degree, itching severity and average length of hospital stay of these two groups were compared.Results:The basic data of the two groups were homogeneous. The difference were not statistically significant( P>0.05). After intervention, the comfort degree of the pocket group was (65.90 ± 7.95) points while the comfort degree of the vest group was (77.04 ± 5.96) points. The difference was statistically significant ( t = 7.93, P<0.01). The degree of pruritus was (12.72 ± 3.95) points in the pocket group and (8.00 ± 1.20) points in the vest group.The difference was statistically significant ( t = 8.08, P<0.05). The mean length of hospital stay in the pocket group was (15.86 ± 5.83) days and (11.02 ± 3.38) days in the vest group. The difference was statistically significant ( t = 5.08, P<0.01). Conclusions:When using topical mirabilite for patients with acute severe pancreatitis, the use of adjustable mirabilite vest can significantly improve patients′ comfort, reduce itching, and reduce the number of hospital days, which has the value of promotion and use.

Mobile bearing and fixed bearing unicompartmental knee arthroplasty for medial knee osteoarthritis / 中华骨科杂志

Objective To study the short-term clinical outcomes of unicompartmental knee arthroplasty for medial compartmental knee osteoarthritis,and to compare 2 kinds of unicompartmental prosthesis.Methods From March 2010 to June 2013,data of 43 patients underwent unicompartmental knee arthroplasty (UKA) were retrospectively analyzed.17 patients (17knees) used rotating platform prosthesis,and 26 patients (28 knees) used fixed bearing prosthesis.There were 7 males (7 knees)and 9 females (10 knees) in rotating platform group,with an average age of 64.1 years (range,54-82 years);while 10 males (10knees) and 17 females (18 knees) in fixed bearing group,with an average age of 62.2 years (range,43-79 years).All patients presented signs of narrowed medial joint space,medial tenderness and pain on weight-bearing.X-ray and MRI were used for documenting joint narrowing and cartilage defect.The pain and the knee functions were recorded both pre and post-operatively with knee society score (KSS),2 cases of simultaneous anterior cruciate ligament (ACL) reconstruction were assessed with TegnerLysholm knee scoring scale as well.Results All 43 patients were followed up for 6 month to 37 months,and the average duration was 21.1 months.There were no dislocations,joint infection,deep venous thrombosis,prosthetic loosening,etc.The KSS in rotating platform group was 56.11 ±9.51 preoperatively,and 92.23±5.46 postoperatively.While the KSS in fixed bearing group was 57.11 ±9.56,and 93.69±6.37,respectively.There were statistical differences comparing between preoperative and postoperative KSS knee scores.There was no significant difference in KSS scores between rotating platform group and fixed bearing group.Conclusion Unicompartmental knee arthroplasty is a less invasive and effective method for knee osteoarthritis in medial compartment with less complications.There was no significant difference in clinical outcomes between rotating platform and fixed bearing design in terms of patients' satisfactory rate,clinical and functional outcomes in this short-term follow-up study.

Effect of downregulation of Tiam1 by siRNA on esophageal squamous cell carcinoma EC9706 cells / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To explore the effect of downregulation of Tiam1 by siRNA on the esophageal squamous cell carcinoma (ESCC) EC9706 cells, and provide theoretical basis for gene therapy of ESCC using Tiam1 as a molecular target.</p><p><b>METHODS</b>Tiam1 siRNA was transfected into EC9706 cells, and expression changes of Tiam1 mRNA and protein after transfection were detected by quantitative real-time PCR and Western blotting. Cell proliferation was analyzed using CCK-8 kit. Cell cycle and apoptosis of the EC9706 cells were assessed by flow cytometry. Cell cycle-related proteins and cell apoptosis-associated proteins were analyzed by Western blotting.</p><p><b>RESULTS</b>Compared with the untreated group and control siRNA group, the relative expression levels of Tiam1 mRNA (1.00 and 0.11 ± 0.02) were not significantly different (P > 0.05). The relative expression levels of Tiam1 mRNA in the Tiam1 siRNA group at 24, 48 and 72 h after transfection were 0.30 ± 0.04, 0.09 ± 0.01 and 0.09 ± 0.006, respectively, significantly lower than that of the untreated group (P < 0.05 for all). The expression level of Tiam1 protein at 24 h after Tiam1 siRNA transfection in the EC9706 cells was 0.11 ± 0.02, significantly lower than that in the un-treated group (0.44 ± 0.05) and control siRNA group (0.44 ± 0.04, P < 0.05 for all). The percentages of G0/G1 cells in the Tiam1 siRNA group, untreated group and control siRNA group were (54.48 ± 2.14)%, (40.69 ± 1.85)% and (41.78 ± 1.31)%, respectively (P < 0.01). The percentages of S phase cells in the Tiam1 siRNA group, untreated group and control siRNA group were (27.18 ± 1.65)%, (32.32 ± 1.15)% and (30.35 ± 1.09)%, respectively (P < 0.01). The expression levels of cyclin D1 protein in the untreated group, control siRNA group and Tiam1 siRNA group were 0.43 ± 0.02, 0.41 ± 0.01 and 0.11 ± 0.02, respectively (P < 0.05). The expression levels of p27 protein in the untreated group, control siRNA group and Tiam1 siRNA group were 0.10 ± 0.01, 0.09 ± 0.02 and 0.20 ± 0.02, respectively (P < 0.05). The ratios of early apoptotic cells in the untreated group, control siRNA group and Tiam1 siRNA group were (10 ± 0.9)%, (10 ± 0.5)% and (27 ± 0.7)%, respectively (P < 0.01). The expression levels of Mcl-1 protein in EC9706 cells of untreated group, control siRNA group and Tiam1 siRNA group were 0.47 ± 0.12, 0.48 ± 0.13 and 0.16 ± 0.02, respectively (P < 0.05). The expression levels of Bcl-2 protein in EC9706 cells of the untreated group, control siRNA group and Tiam1 siRNA group were 0.49 ± 0.08, 0.50 ± 0.05 and 0.04 ± 0.03, respectively (P < 0.05). The caspase-3 activities in the untreated group, control siRNA group and Tiam1 siRNA group were 2.3 ± 0.09, 2.3 ± 0.10 and 16.0 ± 1.50, respectively; and that of caspase-9 were 2.3 ± 0.08, 2.3 ± 0.11 and 14.5 ± 0.9, respectively (P < 0.05 for all).</p><p><b>CONCLUSIONS</b>Tiam1 siRNA can significantly inhibit the proliferation of esophageal cancer EC9706 cells, induce cell cycle arrest and cell apoptosis. These effects are related to the regulation of the expressions of cell cycle-related genes (cyclin D1 and p27) and cell apoptosis-related genes (Mcl-1, Bcl-1, caspase-3 and caspase-9) by Tiam1 siRNA.</p>
