Objective To systematically evaluate the clinical efficacy and safety of Danshen Chuanxiongqin Injection (DCI) in the treatment of angina pectoris. Methods Randomized controlled trials (RCTs) regarding DCI in the treatment of angina pectoris were searched in CNKI, VIP, Wanfang Database, CBM, PubMed, Embase and Cochrane Library by Feb. 2014. Two researchers independently retrieved the RCTs and extracted the information. The Cochrane risk of bias method was used to assess the quality of the included studies, and a meta-analysis was conducted with Review Manager 5.2 software. Results A total of 12 RCTs with 1145 participants were included. The meta-analysis indicated that the combined use of DCI and conventional treatment with western medicine was more effective in the outcomes of the total clinical effective rate [RR=1.27, 95%CI (1.19,1.35), P<0.000 01], the total effective rate of ECG [RR=1.34, 95%CI (1.23,1.46), P<0.000 01], and decrease of plasma viscosity [MD=-0.15, 95%CI (-0.25,-0.05), P=0.004] and fibrinogen [MD=-0.96, 95%CI (-1.14,-0.78), P<0.000 01]. And there were no adverse drug reaction reports. Conclusion Based on this systematic evaluation, DCI combined with conventional therapy is effective and relatively safe in treating angina pectoris, but it still needs larger samples, multi-center, and high quality RCT to verify.

Objective To investigate the characteristics of electroencephalogram (EEG) in patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. Methods In this retrospective study, patients with anti-NMDAR encephalitis who admitted to Xuanwu Hospital of Capital Medical University from January 2012 to June 2015 were enrolled. All patients accepted EEG monitoring at least once, and tumor screening, symptomatic therapy, as well as immunotherapy. Outcomes were assessed by modified Rankin Scale (mRS) 6 and 12 months after immunotherapy, and mRS score 0-2 was defined as favorable outcome. Results Forty-one patients aged (27±12) (13-58) years were enrolled, 19 of whom were male. All patients received EEG monitoring 55 times totally. Among 41 patients in disease peak period, 39 patients (95.1%) had abnormal EEG, 2 patients had normal EEG. The abnormality of brain MRI scan accounted for 51.2%. Abnormal EEG included diffuse slowing (12 patients, 29.3%), epileptic discharges (9 patients, 22.0%), rhythmic delta activity (6 patients, 14.6%), extreme delta brush (EDB) (6 patients, 14.6%), focal slowing (4 patients, 9.8%), and rhythmic delta frequency activity without EDB (2 patients, 4.9%). Clinical items did not show statistically significant difference between the patients with EDB and those without EDB. The patients with normal EEG, epileptic discharges, rhythmic delta activity, or rhythmic delta frequency activity without EDB all had favorable outcomes after 12 months′ treatments. Conclusions The great majority of patients with anti-NMDAR encephalitis had abnormal EEG. EEG could sensitively reflect the changes of brain function and could be helpful in early diagnosis and treatment of this disease. The most common electrographic pattern was found to be diffuse slowing in patients with anti-NMDAR encephalitis. EEG of some patients showed EDB.

Objective To explore the clinical characteristics and influencing factors of primary nephrotic syndrome (PNS) combined with hypercoagulability in children. Methods The clinical data of 57 children with primary PNS were analyzed retrospectively. The clinical features and treatment were compared among high coagulation state group, non high coagulation state group and control group (20 children). At the same time, the differences between the simple nephrotic syndrome group (SNS) and nephritic syndrome group (NNS) in hypercoagulable state were analyzed. In addition, the correlation analysis was performed. Results Among 57 patients, there were 50 patients in high coagulation state group and 7 in non high coagulation state group. There was no significant difference in gender, age and clinical manifestations between two groups (P>0.05). The platelet (PLT) count, platelet aggregation (PCT), albumin (Alb), fibrinogen (Fib), D-dimer (D2) were significantly higher than those in the control group, and there were statistically significant differences (P all<0.01). There were significant differences in the levels of PLT, Fib, D2 and complement C4 between hypercoagulable state group and non hypercoagulable state group (P all<0.05). There were significant differences in HCT, TC, LDL, PT and complement C3 levels between SNS group (n = 32) and NNS group (n =18) in 50 patients with high coagulation state (P<0.05). There was positive correlation between HCT and complement C3 (r=0.30, P<0.05), while there was no correlation between PLT and other indices (P>0.05). All of the 57 patients were improved and has no thrombosis after the treatment. Conclusion Children with primary PNS were usually associated with different degrees of hypercoagulable state, and PLT, Fib, D2 could be used as reference indices for the severity of hypercoagulable state, and the activation of complement system might be related to the occurrence and development of hypercoagulable state.
