Though lack of definite evidences,closed suction drainage after arthroplasty is routinely employed by the majority of orthopaedic surgeons with the aim of preventing the formation of wound haematoma,reducing delayed wound healing and the risk of deep infection.But the optimal time to remove drains is controversial.The usual time to remove drains is 48~72 h after operation when the volume of drains is less than 50ml within 24 h.But some scholars find that the time of draining more than 24 h increases the risk of wound infection.This paper reviews the literature of draining time,and concludes that the optimal time to remove drains is 24 h after the primary arthroplasty.

Objective To explore the correlation between B lymphocyte activation and CD154 expression and lupus anticoagulants (LAC) in patients with systemic lupus erythematosus (SLE). Methods Sixty newly diagnosed SLE patients (SLE group) and 32 healthy controls (control group) were involved. The expressions of CD27 and CD154 in peripheral blood were determined by flow cytometry, and the positive expression rates were computed. The LAC was determined by activated partial thromboplastin time, and the LAC ratio > 1.20 was positive. Results The positive rate of CD27, expression intensity of CD27, positive rate of CD154 and expression intensity of CD154 in SLE group were significantly higher than those in control group: 0.047 ± 0.021 vs. 0.035 ± 0.014, 0.387 ± 0.185 vs. 0.214 ± 0.091, 0.191 ± 0.108 vs. 0.101 ± 0.081 and 0.049 ± 0.018 vs. 0.022 ± 0.012, and there were statistical difference (P<0.05 or <0.01). Among patients with SLE, the LAC positive was in 28 cases, and the LAC negative was in 32 cases. The positive rate of CD27, expression intensity of CD27, positive rate of CD154 and expression intensity of CD154 in SLE patients with LAC positive were significantly higher than those in SLE patients with LAC negative: 0.055 ± 0.023 vs. 0.037 ± 0.014, 0.444 ± 0.179 vs. 0.329 ± 0.123, 0.218 ± 0.101 vs. 0.158 ± 0.044 and 0.058 ± 0.035 vs. 0.020 ± 0.009, and there were statistical differences (P<0.05). Conclusions The B lymphocyte activation and CD154 abnormal expression correlates with generation of LAC in patients with SLE. It provides a basis for the further study on intervening the generation of LAC and reducing the risk of thromboembolism.

Objective To explore the role of Foxp3+ T cells (Tregs) in liver injury induced by chronic intermittent hypoxia. Methods Thirty-two male Wister rats were divided into four groups:control group (A), high-fat diet group (B), intermittent hypoxia group (C), and high-fat diet and intermittent hypoxia group (D). After 4 weeks, blood samples were collected and livers were surgically removed. Using the standard automatic clinical analyzer to test serum levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL- C), alanina aminotransferase (ALT) and aspartato aminotransferase (AST). The MDA content of liver tissue was measured by colorimetrc method. The levels of TNF-αand IL-1βwere measured by radiommunoassay, and the expression of Foxp3 protein was measured by Western blotting technique. Results Serum levels of TC and LDL-C were significantly higher in B group than those of A, C and D groups, and which were higher in D group than those of A and C groups (P<0.05). There were no significant differences in serum levels of TC and LDL-C between A group and C group. Serum levels of ALT, AST, MDA, TNF-αand IL-1βwere significantly higher in C group than those of A group, and which were significantly higher in D group than those of A, B and C groups (P<0.05). There were no significant differences in these indicators between A group and B group, and between B group and C group. Foxp3 protein expression in liver was significantly lower in D group than that of other groups (P<0.05). Conclusion Foxp3+T regulatory cells involve in the regulation of hepatic injury induced by chronic intermittent hypoxia on the basis of a high-fat diet, and which may play an important role in this process of protective immune response.
