Objective To evaluate the effect of chronic disease nursing of traditional Chinese Medicine (TCM) on depression in patients with chronic hepatitis B (CHB).Methods From June 2015 to June 2016, 120 CHB patients with various degree of depression were divided into control group and observation group with 60 each. Patients in control group received routine medical treatment and nursing. Patients in the observation group on the basis of routine medical treatment and nursing were combined with chronic disease nursing of TCM. We compared the difference of SDS score, TCM syndrome and SF-36 score between the two groups before and after intervention.Results After intervention, the SDS score of observation group dropped from (57.95±3.42) to (47.68±4.46). The SDS score of control group dropped from (57.40±3.83) to (49.62±5.30). The SDS score of the observation group was lower than that of the control group (t=2.1619,P<0.05). The total effective rate of TCM syndromes in observation group was 86.67%. The total effective rate of TCM syndromes in control group was 71.67% (χ2=6.4423,P<0.05). The difference total score of SF-36 between before and after in the observation group(1.00 ± 0.65) was higher than that of the control group(0.73 ± 0.74) (t=2.1318,P<0.05). Conclusions The nursing management of chronic diseases in TCM can relieve the depression and improve the quality of life in CHB patients.

This study was aimed to investigate the estrogenic effects ofCoicis Semen in order to preliminarily discuss the mechanism. Mouse uterine weight test and MCF-7 cell proliferation assay were used to evaluate the estrogenic effects ofC. Semen. Reporter gene assays were adopted to explore the action mechanism ofC. Semen. In reporter gene assay, HEK293 cells were co-transfected with pERE-TAL-luc, pβgal-Control, pCXN2-hERα, or pCXN2-hERβ. And the expression of reporter gene luc was controlled by ERE. Mouse uterine weight test showed that compared with the control group, the aqueous extracts ofC. Semen can increase the uterus index of premature female mice (P<0.01). It can significantly promote the proliferation of MCF-7 cells in the medium without estrogen (P<0.01). The reporter gene controlled by ERE technology showed thatwhen mediated by ERα or ERβ respectively, the normalized luciferase activity of aqueous extracts ofC. Semen was significantly higher than activity of the control group (P< 0.05 orP< 0.01). It was concluded that the aqueous extracts ofC.Semen can increase the uterus index of premature female mice and promote the proliferation of MCF-7 cells in the medium without estrogen. We found the estrogenic effects ofC. Semen for the first time. And the estrogenic effects ofC. Semen were mainly mediated by ERβ.

Objective:To investigate the correlation of serum high-sensitivity cardiac troponin T (hs-cTnT) level with major adverse cardiovascular events (MACE) in patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI) and to explore its predictive value.Methods:It was a case-control study. Clinical data of 731 patients with CCS who underwent PCI in the Affiliated Zhongshan Hospital of Fudan University between May 2019 and April 2020 were retrospectively analyzed. Baseline clinical characteristics and pre/postoperative laboratory results were gathered, and patients were followed up and the incidence of MACE was documented. The correlation of serum hs-cTnT levels with MACE was analyzed, and the threshold of hs-cTnT for predicting the occurrence of MACE was determined.Results:Among 731 patients there were 560 males (76.61%) with the age of (64.05±9.48) years. Patients were followed up for 29.9 (18.8, 35.3) months, and MACE occurred in 216 cases (MACE group), and did not occur in 515 cases (control group). The X-tile software analysis showed that the optimal cutoff value of post-PCI hs-cTnT was 4.17×upper reference limit (URL) for predicting MACE ( P=0.033). Multivariate Cox regression analysis revealed that postoperative cTnT>6×URL was an independent risk factor for MACE in CCS patients after PCI ( HR=1.87, 95% CI: 1.19-2.94, P=0.007). The net reclassification index pairwise comparison results indicated that hs-cTnT>6×URL had the better predictive performance for MACE in CCS patients after PCI compared to 7×URL, 8×URL, 9×URL, 10×URL and 15×URL (all P<0.05). Conclusion:Postoperative hs-cTnT>6×URL is an independent risk factor for MACE in CCS patients after PCI, and hs-cTnT>6×URL is the optimal threshold for predicting the risk of MACE.
