Objective To measure the serum levels of angiopoietin-like protein (ANGPTL) 3, ANGPTL4 and RANKL in patients with rheumatoid arthritis (RA), and the relationship between ANGPTL3/ANGPTL4 and clinical manifestations were analyzed. Methods Blood samples were drawn from 72 patients with RA and 28 healthy subjects. Serum levels of ANGPTL3, ANGPTL4 and RANKL were tested by enzyme linked immuno-sorbent assay (ELISA). Nonparametric rank sum test was used for the comparisons between groups and Spearmanˊs correlation test was used for correlation analysis. Results ① The serum level of ANGPTL3 was significantly increased in RA group compared to healthy group [800.325(577.477, 1 750.636) pg/ml vs 487.900 (382.340, 565.499) pg/ml, P<0.05, Z=-6.082]. ② The serum level of ANGPTL4 was significantly increased in RA group compared to healthy group [1 036.199(853.347, 1 746.677) pg/ml vs 706.095(558.571, 807.302) pg/ml, Z=-5.962, P<0.05].③ The serum levels of ANGPTL3 and ANGPTL4 in RA patients were increased with the rise of disease activity (DAS 28) [ANGPTL3 in the low disease activity groupwas 457.265 (373.709, 605.296) pg/ml, that of the moderate disease activity group was 785.815(679.156, 1 308.785) pg/ml, that of the high disease activity group was 1 502.038 (817.713, 1 960.493) pg/ml, P<0.05; ANGPTL4 in the low disease activity group was 737.604 (467.040, 918.222) pg/ml, that of the moderate disease activity group was 991.227 (819.456, 1 699.972) pg/ml, and that of the high disease activity group was 1 842.310 (1 252.023, 2 669.902) pg/ml, P<0.05].④ANGPTL3 and ANGPTL4 was positively correlated with RANKL (r=0.554, 0.619, P<0.01).⑤ The serum level of ANGPTL4 was significantly increased in patients with bone destruction, compared to those without bone destruction [1 624.071(949.432, 2 622.371) pg/ml vs 927.590(737.604, 1 409.798) pg/ml, Z=-2.483, P<0.05]. Conclusion The serum levels of ANGPTL3 and ANGPTL4 are increased in RA, and are both positively correlated with disease activity, moreover, ANGPTL4 is associated with pathological bone destruction.

Objective To evaluate the clinical efficacy of nerve-related acupoints electrical stimulation in preventing urinary retention after hemorrhoid surgery. Method Ninety-seven patients were randomized into two groups: the treatment group received nerve-related acupoints electrical stimulation 1 h after Milligan-Morgan hemorrhoidectomy for mixed hemorrhoids, while the control group was taken as a blank control. The incidence of postoperative urinary retention, residual urine volume after the first urination, general urinary condition score, and satisfaction evaluation were compared between the two groups. Result The incidence of postoperative urinary retention and residual urine volume after the first urinary were lower, and the general urination condition and satisfaction evaluation were higher in the treatment group compared to those in the control group. Conclusion Nerve-related acupoints electrical stimulation can prevent and reduce the adverse reactions such as urinary retention after hemorrhoidectomy, and it can effectively protect the bladder function and improve the prognosis.
