Study on the distribution law of TCM syndrome types and influencing factors based on 1 684 patients with unstable angina pectoris of coronary heart disease / 国际中医中药杂志

Objective:To investigate the distribution law of TCM syndrome types and the differences in influencing factors among different syndrome types in unstable angina pectoris (UA), so as to provide an objective basis for TCM syndrome differentiation and treatment of UA.Methods:A retrospective study chose 1 684 inpatients in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Henan University of Chinese Medicine from August 2015 to April 2019. Epidata 3.0 software was used to input general information of patients [gender, age, length of hospital stay, BMI, systolic blood pressure (SBP), diastolic blood pressure (DBP)], laboratory indicators[TC, TG, HDL-C, LDL-C, fibrinogen (FIB), thrombin time (TT), D-dimer (D-dimer), HbA1c], TCM syndrome types (qi and yin deficiency syndrome, phlegm turbidity and obstruction syndrome, qi deficiency and blood stasis syndrome, heart blood stasis syndrome, qi stagnation and blood stasis syndrome, heart and kidney yang deficiency syndrome) and other information. A database was established to analyze the distribution of TCM syndrome types and the relationship with the general information of patients, blood lipids, blood sugar and coagulation indexes. Logistic regression was used to analyze the influencing factors of different syndrome types.Results:The distribution of syndrome types in 1 684 UA patients was as follows: qi and yin deficiency syndrome (44.7%), phlegm turbidity and obstruction syndrome (35.3%), qi deficiency and blood stasis syndrome (7.4%), heart blood stasis syndrome (5.3%), qi stagnation and blood stasis syndrome (4.6%), heart and kidney yang deficiency syndrome (2.6%); more men than women ( P<0.05); there were significant differences in the distribution of gender, age, BMI, TC, and HDL-C among the 6 syndrome types ( P<0.05); the age of patients with phlegm turbidity and obstruction syndrome was younger than that of qi and yin deficiency syndrome and heart blood stasis syndrome ( P<0.05); the age of patients with qi stagnation and blood stasis syndrome was younger than that of qi and yin deficiency syndrome, heart blood stasis syndrome, and heart kidney yang deficiency syndrome ( P<0.05); BMI of patients with phlegm turbidity and obstruction syndrome was higher than that of qi and yin deficiency syndrome and qi stagnation and blood stasis syndrome ( P<0.05); the level of TC in patients with phlegm turbidity and obstruction syndrome was lower than that of qi and yin deficiency syndrome and qi deficiency and blood stasis syndrome ( P<0.05); the level of HDL in patients with qi and yin deficiency syndrome was lower than that in qi deficiency and blood stasis syndrome and qi stagnation and blood stasis syndrome. Binary Logistic regression analysis found that TC [ OR(95% CI)=0.761(0.592, 0.978)] and HDL-C [ OR(95% CI)=2.131(1.145, 3.966)] were independent influencing factors for predicting qi deficiency and blood stasis syndrome ( P<0.05); age[ OR(95% CI)=1.017 (1.008, 1.026)], length of hospital stay [ OR(95% CI)=1.019 (1.001, 1.038)], DBP [ OR(95% CI)=0.984(0.975, 0.993)] and HDL-C [ OR(95% CI)=0.984(0.975, 0.993)] were independent influencing factors for predicting qi and yin deficiency syndrome ( P<0.05); age [ OR(95% CI)=0.965 (0.946, 0.985)], and HDL-C [ OR(95% CI)=2.329(1.206, 4.500)] were independent influencing factors for predicting qi stagnation and blood stasis syndrome ( P<0.05); age [ OR(95% CI)=0.982 (0.973, 0.991)], length of hospital stay [ OR(95% CI)= 0.978 (0.958, 0.997)], BMI [ OR(95% CI)=1.048 (1.015, 1.082)], DBP [ OR(95% CI)=1.014 (1.004, 1.024)] and HDL-C [ OR(95% CI)=0.505 (0.351, 0.726)] were independent influencing factors for predicting phlegm turbidity and obstruction syndrome ( P<0.05); age [ OR(95% CI)=1.031(1.003, 1.060)] and DBP [ OR(95% CI)=1.028(1.001, 1.056)] were independent influencing factors for predicting heart kidney yang deficiency syndrome ( P<0.05). Conclusion:The distribution of TCM syndrome types in UA shows a certain regularity, among which qi and yin deficiency syndrome and phlegm turbidity and obstruction syndrome are more common. Gender, age, BMI, TC, HDL-C are different among TCM syndrome types, which can provide some reference for UA TCM syndrome differentiation and treatment.

The effect of electroacupuncture stimulation at acupoint Zusanli on the model of Staphylococcus aureus osteomyelitis / 中华创伤骨科杂志

Objective:To explore whether the electroacupunture stimulation (ES) at acupoint Zusanli (ST36) can inhibit the bone loss caused by Staphylococcus aureus (SA) infection and its mechanism in a model of SA osteomyelitis.Methods:Twelve male C57 BL/6 mice aged 10 to 12 weeks were randomly divided into 2 even groups ( n=6) for SA infection + ES or SA infection only. After ES at ST36 was conducted for 4 weeks in the model of SA osteomyelitis, samples were harvested from the femora and tibiae. Micro-CT reconstruction was performed to detect trabecular bone volume fraction (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), connectivity density (Conn.Dn) to analyze changes in bone mass. Leptin receptor (LEPR) staining was performed to detect osteoblasts. Tartrate resistant acid phosphatase (TRAP) staining was used to detect the changes in osteoclasts. The changes in plasma inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA). Results:Micro-CT results showed that the BV/TV, Tb.N, Tb.Th, and Conn.Dn in the cancellous bone in the target areas in the SA + ES group were all higher than those in the SA group, LEPR immunofluorescence results indicated that the number of osteogenic precursor cells in the ES group was larger than that in the SA group, and serum ELISA indicated a decrease in inflammatory factors in the blood in the SA+ES group compared with the SA group. There were significant differences in the comparisons above ( P<0.05). There was no significant difference in the number of osteoclasts on the surface of trabecular bone between the 2 groups in TRAP staining. Conclusion:ES may slow down infectious bone destruction by inhibiting the inflammatory response induced by SA infection and by inducing aggregation and differentiation of mesenchymal stem cells into trabecular bone.

Outcomes of 138 myelodysplastic syndrome patients with HLA-matched sibling donor allogeneic hematopoietic stem cell transplantation / 中华血液学杂志

Objective@#To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) .@*Methods@#The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored.@*Results@#①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ2=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ2=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ2=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ2=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) .@*Conclusions@#HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

Outcomes and prognostic factors of myelodysplastic syndrome patients with allogeneic hematopoietic stem cell transplantation / 中华血液学杂志

Objective@#To evaluate the outcomes and prognostic factors of myelodysplasia syndrome (MDS) patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) .@*Methods@#165 cases of MDS who underwent allo-HSCT from Jan. 2010 to Mar. 2018 were analyzed retrospectively, focusing on the overall survival (OS) , disease free survival (DFS) , relapse, non-relapse mortality (NRM) and their related risk factors.@*Results@#Of all the 165 cases, 105 were male and 60 were female. The 3-year OS and DFS rate were 72.5% (95%CI 64.9%-80.1%) and 67.4% (95%CI 59.17%-75.63%) , respectively. The 3-year cumulative incidence of relapse and NRM were 12.11% (95%CI 7.03%-18.65%) and 20.44% (95%CI 14.15%-27.56%) , respectively. HCT-comorbidity index (P=0.042, HR=2.094, 95%CI 1.026-4.274) was identified as independent risk factor for OS by the multivariate analysis. Intensive chemotherapy before HSCT or hypomethylation agents treatment had no effects on OS[ (67.0±7.5) %vs (57.7±10.9) %, χ2=0.025, P=0.874].@*Conclusions@#allo-HSCT is a promising means for MDS, and NRM is the major cause of treatment failure. MDS with refractory anemia with excess blasts and secondary acute myeloid leukemia patients may not benefit from intensive chemotherapy or hypomethylation agents treatment before HSCT.
