Baekground:Obstetric hemorrhage is a major cause of maternal death during cesarean delivery.The objective of this retrospective observational study was to evaluate the efficacy and safety of intra-operative cell salvage (IOCS) in cesarean section.Methods:We included a total of 361 patients diagnosed with central placenta previa who underwent cesarean section from May 2016 to December 2018.In this study,196 patients received autologous transfusion using IOCS (IOCS group) and 165 patients accepted allogeneic blood transfusion (ABT group).Propensity score matched analysis was performed to balance differences in the baseline variables between the IOCS group and ABT group.Patients in the IOCS group were matched 1:1 to patients in the ABT group.Results:After propensity score matching,137 pairs of cases between the two groups were successfully matched and no significant differences in baseline characteristics were found between the IOCS group and ABT group.Patients in the IOCS group were associated with significantly shorter length of hospital stay,compared with ABT group (8.9 ±4.1 days vs.10.3 ± 5.2 days,t=-2.506,P =0.013).The postoperative length of hospital stay was 5.3 ± 1.4 days for patients in the IOCS group and 6.6 ± 3.6 days for those in the ABT group (t =-4.056,P ＜ 0.001).The post-operative hemoglobin level in the IOCS group and ABT group was 101.3 ± 15.4 and 96.3 ± 16.6g/L,respectively,which were significantly different (t=2.615,P=0.009).Allogeneic red blood cell transfusion was significantly lower at 0 unit (range:0-11.5 units) in the IOCS group when compared with 2 units (range:1-20 units) in the ABT group (P ＜ 0.001).Condusions:This retrospective observational study using propensity score matched analysis suggested that IOCS was associated with shorter length of postoperative hospital stay and higher post-operative hemoglobin levels during cesarean delivery.

Long non-coding RNAs(lncRNAs)can be involved in regulating gene expression through multiple interactions with DNA,RNA or proteins.Studies have shown that lncRNAs not only regulate innate immune response,but also regulate immune cell development and adaptive immunity.According to recent reports,a number of lncRNAs play a role in the pathogenesis of immune-mediated inflammatory diseases,including systemic lupus erythematosus(SLE),and may become a diagnostic marker and prognostic reference for diseases.This paper summarizes the research progress of lncRNAs in SLE,with the hope of providing more new ideas and methods for the study of SLE.

Objective To evaluate the long-term clinical effect of dual anti-collagen membranes in guided tissue regeneration(GTR). Methods This randomized clinical trial included 26 teeth in 24 patients, presenting a total of 31 lesions consisting of intrabony defects and furcation defects. Twenty-six teeth were divided into two groups and treated by GTR with dual anti-collagen membranes and atelocollagen membranes, respectively. At baseline, 6 months, 1, 3 and 6 years, the following parameters were recorded; clinical attachment level, probing depth, gingival recession and the quantity of alveolar bone analyzed by computer assisted densitometry image analysis (CADIA). Results At 1 year after GTR surgery, the gain of clinical attachment in dual anti-collagen membranes group was (3. 93 ± 1. 74) mm,compared with (2. 25 ± 1. 90) mm in atelocollagen group(P =0. 044). The increasing of the value of CADIA in dual anti-collagen membrane and atelocollagen group were (53. 14 ± 21. 35) and (32. 96 ± 17. 97 ), P = 0. 031. At 3 and 6 years, clinical parameters remained basically stable in both groups, compared to that at 1 year after surgery. Conclusions The regeneration of periodontal tissues obtained by GTR with dual anti-collagen membranes could be maintained on a long-term basis.

The combination of Danggui and Honghua (GH) is a popular herb pair commonly used in clinic for the treatment of blood stasis syndrome in China. To evaluate the activating blood circulation and dissipating blood stasis effects of the combination of different proportions of Danggui and Honghua on acute blood stasis rats, and optimize the proportion of GH to have the best activating blood circulation and dissipating blood stasis effect. Acute blood stasis rat model was induced by subcutaneous injection of adrenaline and ice water bath. The blood stasis rats were administrated intragastrically with GH (1 : 0, 4 : 1, 2 : 1, 3 : 2, 1 : 1, 2 : 3, 1: 2, 1 : 4 and 0 : 1) extracts. The whole blood viscosity (WBV), plasma viscosity (PV), and high shear whole blood relative index (HSWBRI), low shear whole blood relative index (LSWBRI), and erythrocyte aggregation index (EAI) were tested to observe the effects of GH on hemorheology of blood stasis rats. And the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of GH on platelet aggregation index of blood stasis rats. In addition, the prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT) and plasma fibrinogen (FIB) were tested to observe the effects of GH on blood coagulation function of blood stasis rats. Then principal component analysis and multi-attribute comprehensive index methods were both used to comprehensively evaluate the total activating blood circulation and dissipating blood stasis effects of GH. The results showed that the hemorheological indexes and coagulation parameters of model group both had significant differences with normal group. Compared with model group, GH (1 : 0, 4 : 1, 2: 1, 3 : 2, 1 : 1, 2 : 3, 1 : 2, 1 : 4 and 0 : 1) could improve all the blood hemorheology indexes and regulate part indexes of blood coagulation function and platelet aggregation in acute blood stasis rats. Based on principal component analysis and multi-attribute comprehensive index methods, GH 1 : 1 and GH 3 : 2 both had the best effect of blood circulation and dissipating blood stasis, and the effect of GH 1 : 1 was slightly better than GH 3 : 2. These results suggest that GH could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats. The optimized proportion of GH was consistent with regulations of medicine usage that GH 1 : 1 had the highest frequency used in traditional Chinese formulae. It could provide scientific basis for more effective application of the compatibility between Danggui and Honghua in modern clinic medicine.
