Objective To observe the curative effect in patients with systemic lupus erythematosus(SLE) complicated by moderate or severe thrombocytopenia with a blood platelet count(BPC) of under 50 × 109/L and analyze its related factors. Methods We retrospectively analyzed the clinical data on 109 SLE patients with mod-erate or severe thrombocytopenia. Results Of the 109 patients,82(75.2%)had complete response(CR),15 (13.8%)had partial response(PR),and 12(11.0%)had no response(NR),respectively. As compared with the CR+PR group,the NR group had a higher incidence rate of decreased bone marrow megakaryocyte(P < 0.05). However,there were no significant differences between the two groups in SLEDAI scores,rates of positive PAIg and ACA,and levels of C3 and C4(P>0.05 for all comparisons). The total effectiveness rate did not differ signifi-cantly between MP pulse therapy and high-dose corticosteroid therapy. Conclusions A decrease in bone marrow megakaryocytes can be an adverse factorfor affecting the efficacy in patients with SLE complicated by moderate or severe thrombocytopenia.

Objective:To observe the changes of plasma oxytocin (OT), arginine vasopressin (AVP) and anxiety after exercise intervention in male opioids-dependent patients.Methods:Forty-five male opioids addicts who met the inclusion criteria and voluntarily participated in exercise rehabilitation were enrolled.According to stratified random sampling, all subjects were divided into exercise group ( n=22) and control group( n=23). Exercise group attended aerobic exercise combined with resistance training intervention, 5 times per week for 8 weeks.Aerobic exercise was mainly treadmill and elliptical, while resistance training was based on strength and endurance training.Subjects completed self-rating anxiety scale (SAS) and Chinese perceived stress perception scale (CPSS) before and after intervention, as well as physical fitness tests. Besides, plasma OT and AVP levels were detected.Independent sample t-test, paired sample t-test, and Chi-square test were conducted by using SPSS 20.0 software. Results:Before the intervention, there were no significant differences between the two groups in demography, drug history, SAS, CPSS, plasma OT and AVP(all P>0.05). The overall anxiety detection rate was 66.67%, the scores of SAS and CPSS were both higher than the Chinese norm, and the difference was significant(both P<0.01) . After the intervention, the levels of plasma AVP, the scores of SAS and CPSS in the exercise group (AVP(19.57±2.23)pg/ml, SAS(50.17±10.09), CPSS(36.59±6.36)) were significantly lower than those in the control group (AVP(22.53±2.56)pg/ml, SAS(57.12±12.00), CPSS(43.09±5.57), all P<0.05), and plasma OT((61.98±5.27) pg/ml) was significantly higher than that in the control group ((54.64±7.62) pg/ml)( P<0.01). Compared with baseline, maximal oxygen uptake(VO 2max), 1 min push-ups and sitting body flexion increased significantly in the exercise group (all P<0.05). Conclusion:Opioids drug addicts were prone to excessive stress and anxiety and other negative emotions in the process of drug withdrawal. Eight-week aerobic combined with resistance exercise changed the plasma OT and AVP levels of opioids addicts, effectively alleviated the perceived stress, improved the anxiety state and their health related fitness level.
