Objective To explore the relationship between acute coronary syndrome(ACS) and inflammation , and to observe the short-term effect of Xiangdan Injection(XI) in treating ACS and on inflammatory markers.Methods One hundred and twenty cases of ACS were randomized into two groups: 90 cases in treatment group and 30 in control group. All of the patients received the routine treatment, and the treatment group treated with XI additionally. The therapeutic effect was observed and plasma contents of inflammatory markers such as C-reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor ?(TNF-?) were detected before and after treatment.Results The effect of treatment group was better than that of the control group(P

Objective To evaluate the therapeutic effect of modifiedHuanglian-Jiedudecoction for resistant hypertension and explore its possible mechanism.Methods A total of 90 patients with resistant hypertension were recruited and randomly divided into a treatment group and a control group, 45 patients in each group. The control group was treated with oral administration of irbesartan and hydrochlorothiazide tablets and controlled-release nifedipine tablets, while the treatment group was further added modifiedHuanglian-Jiedu decoction for 4 weeks. Plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) were measured by radioimmunoassay.Rusults The total efficiency according to the TCM syndrome in the treatment group was 86.7%(39/45) which was higher than 64.4%(29/45) in the control group(χ2=4.873,P=0.027). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after the treatment in both groups ( SBP in the treatment group: 119.26 ± 9.34 mmHgvs.172.11 ± 10.52 mmHg,t=25.201,P<0.01; DBP in the treatment group: 78.18 ± 7.21 mmHgvs.111.12 ± 11.16 mmHg,t=16.631, P<0.01; SBP in the control group: 145.21 ± 7.56 mmHgvs.171.32 ± 11.15 mmHg,t=13.002,P<0.01; DBP in the control group: 93.57±8.13 mmHgvs. 109.89 ± 12.21 mmHg,t=7.463,P<0.01), while the decrease of SBP (t=14.487,P<0.01) and DBP (t=9.501, P<0.01) in the treatment group was more greater than those in the control group. The control rate of blood pressure in the treatment and control groups were 73.3% (33/45) and 55.6% (25/45), respectively, there had no significant difference (χ2=2.376,P=0.123). The plasma ET in the treatment group was significantly decreased than that in the control group (75.68 ± 10.67 ng/Lvs.112.79 ± 12.26ng/L;t=15.317,P<0.05), and CGRP significantly increased (49.87 ± 4.75 ng/Lvs.33.87 ± 7.89 ng/L;t=11.654,P<0.05).Conclusion Modified Huanglian-Jiedudecoction may have some therapeutic effect for resistant hypertension, its mechanism may be involved in ET decreasing and CGRP increasing.

Mesenchymal stem cells (MSCs) are multipotent stem cells that differentiate into a variety of cell types. Low frequency pulsed electromagnetic fields (LFPEMFs) therapy can causes biochemical changes at the cellular level to accelerate tissue repair in mammals. So, we tested the hypothesis that LFPEMFs can promote chondrogenic differentiation of rat bone marrow-derived mesenchymal stem cells (rBMSCs) in vitro. The rBMSCs were isolated by adherence method and the third-generation of the rBMSCs were randomly divided into LFPEMFs groups, chondrocyte-induced group and control group. LFPEMFs groups with complete medium were exposed to 50Hz, 1mT PEMFs for 30 min every day, lasting for 10, 15 and 20 d, respectively. Chondrocyte-induced group were treated with chondrogenic media, while control groups were only cultured with complete medium. The mRNA expressions of type II-collagen (Col II) and aggrecan were determined by Real-time fluorescent quantitation PCR. The protein expression of Col II and aggrecan were detected with toluidine blue stain or immunocytochemical stain, respectively. The result showed that the mRNA and protein expression level of Col-II and aggrecan were significantly higher in the LFPEMFs group or chondrocyte-induced group, compared to the control group. It suggest that LFPEMFs could contribute to rBMSCs to differentiate into chondrogenic differentiation in vitro.

Objective:To investigate the value of preoperative MRI measurements of hamstring (semitendinosus+gracilis) tendon cross-sectional area in predicting intraoperative graft diameter for anterior cruciate ligament reconstruction (ACLR).Methods:A total of 265 preoperative MRI were retrospectively collected in the Third Affiliated Hospital of Southern Medical University from January 2013 to August 2020 for patients who underwent single-bundle ACLR of hamstring tendon. Patients were divided into a graft diameter≥8 mm group (129 patients) and a graft diameter<8 mm group (136 patients) according to intraoperative graft diameter. The cross-sectional areas of the semitendinosus and gracilis tendons were measured at the largest level of the femoral condyle on preoperative MRI cross-sectional images, and the two were summed to obtain the cross-sectional area of the hamstring tendon. The independent samples t-test was used to compare the differences in the cross-sectional area of each tendon between the graft diameter≥8 mm group and the graft diameter<8 mm group. The Spearman correlation analysis was used to assess the correlation between tendon cross-sectional area and intraoperative graft diameter. Multi-factor logistic regression analysis was used to screen the influence of tendon cross-sectional area on intraoperative graft diameter. The effectiveness of intraoperative graft diameter≥8 mm was assessed by plotting the receiver operating characteristic curves. Results:Intraoperative measurement of graft diameter was 7.5 (7.5, 8.0) mm. The cross-sectional area of the popliteal tendon was (21.4±4.6) mm 2 in the graft diameter≥8 mm group and (15.6±3.7) mm 2 in the graft diameter<8 mm group. Statistically significant differences were found in the cross-sectional areas of the semitendinosus, soleus and hamstring tendons between the graft diameter≥8 mm group and graft diameter<8 mm group ( t=-10.26, -10.29, -11.47, P<0.001). Intraoperative graft diameter was positively correlated with the cross-sectional area of the semitendinosus, gracilis, and hamstring, with correlation coefficients of 0.57 ( P<0.001), 0.58 ( P<0.001), and 0.62 ( P<0.001), respectively. Multi-factor logistic regression showed that popliteal tendon cross-sectional area was a predictor of intraoperative graft diameter (OR=1.45, 95%CI 1.32-1.59, P<0.001). The area under the curve for popliteal tendon cross-sectional area to predict intraoperative graft diameter≥8 mm was 0.838 (95%CI 0.792-0.885), with a critical value of 20.0 mm 2, a sensitivity of 0.581, and a specificity of 0.941. Conclusion:The measurement of the cross-sectional area of the hamstring muscle on preoperative MRI can predict the diameter of the autologous hamstring graft of ACLR.
