OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

Glaucoma, currently the world's first irreversible blindness, is a complex multifactorial disease with a genetic predisposition, and pathologically elevated intraocular pressure is its risk factor. The pathogenesis of glaucoma is not fully understood, and most existing studies are based on animal models, with mice as the main research object, and the pathological damage process of glaucoma is reconstructed through experimental induction means or transgenic manipulation to further investigate the relevant pathogenesis and pathological changes. The technique of experimentally induced construction of glaucoma mouse models has been studied by many scholars and is gradually becoming mature. And as research in molecular biology and genetics has advanced, more and more studies have focused on the disease genes associated with glaucoma, and transgenic mouse models have become a hot topic in recent years. In contrast to experimental manipulation to control a single factor, gene editing is better able to simulate the complex process of disease pathogenesis. This paper focuses on providing a more complete direction and strategy for model selection in the future research by describing the progress of research on relevant transgenic mouse model of glaucoma.

OBJECTIVE: To understand the biological characteristics of polycythemia vera (PV) patients with myeloid fibroplasia, and further analyze the risk factors affecting myeloid fibroplasia in PV patients, so as to provide ideas for predicting the occurrence of myeloid fibroplasia in PV patients. METHODS: Forty patients with PV in the Department of Hematology, Xiyuan Hospital of China Academy of Chinese Medical Sciences were collected and divided into two groups, with (hyperplasia group) and without (Non-proliferative group) hyperplasia of bone marrow fibers. The differences of basic clinical characteristics, blood routine, biochemistry, bone marrow cells, coagulation function and other indicators between the two groups were compared, and the independent risk factors affecting the proliferation of bone marrow fibrous tissue in PV patients were further analyzed by multivariate regression. RESULTS: Compared with Non-proliferative group, the JAK2 mutation rate (95% vs 70%，P=0.037), eosinophilic cell count (0.19 vs 0.11, P=0.047) and eosinophilic percentage (1.84 vs 1.27, P=0.001) in PV patients with hyperplasia were significantly increased, triglycerides (1.55 vs 1.91, P=0.038) and low-density lipoprotein (1.50 vs 3.08, P=0.000) were significantly reduced, bone marrow hematopoietic volume (0.85 vs 0.6, P=0.001), granulocyte/erythrocyte ratio (3.40 vs 1.89, P=0.033), lymphocyte/erythrocyte ratio (0.60 vs 0.42, P=0.033), and granulocyte+lymphocyte/erythrocyte ratio (3.72 vs 2.37, P=0.026) were significantly increased, thrombin time (18.84 vs 18.12, P=0.043) was significantly prolonged. Multivariate regression analysis results showed that peripheral blood eosinophil ≥2% and low-density lipoprotein ≤2 mmol/L were independent risk factors for bone marrow fibrous tissue hyperplasia in PV patients (P<0.05). CONCLUSION Increased proportion of peripheral blood eosinophils and decreased low density lipoprotein are risk factors for bone marrow fibrous tissue hyperplasia in PV patients.

Objective: To investigate the value of uterine morphological parameters and endometrial T₂ signal intensity (T₂-SI) in evaluating the degree of the fibrotic repair secondary to endometrial injury. Methods: From Sep. 2018 to Feb. 2023, this study prospectively enrolled 29 patients with fibrotic repair secondary to severe endometrial injury (severe group), 17 patients with fibrotic repair secondary to mild to moderate endometrial injury (mild to moderate group), and 40 healthy women of reproductive age (control group) in Nanjing Drum Tower Hospital. The length of uterine cavity (LUC), length of cervix and isthmus (LCI), width of upper uterine cavity (WUUC) and width of lower uterine cavity (WLUC) were measured using magnetic resonance imaging. T₂-SI of endometrium and subcutaneous fat of buttocks were measured, and endometrial normalized T₂-SI (nT₂-SI; T₂-SI of endometrium/T₂-SI of subcutaneous fat of buttocks) was calculated. Statistical analyses of data were performed using one-way analysis of variance, Mann-Whitney U test, intraclass correlation coefficient, Spearman rho test, area under the receiver operating characteristic curve (AUC). Results: LUC, WUUC, WLUC and endometrial nT₂-SI of severe group [(19.7±3.5) mm, (26.9±6.4) mm, (7.9±1.4) mm, 0.73±0.11, respectively] were significantly lower than those of the control group (all P<0.01), while LCI and WUUC/LUC [(51.3±7.3) mm and 1.38±0.34] were significantly higher than those of the control group (all P<0.001). LUC and WLUC of severe group were significantly lower than those of mild to moderate group [(32.4±5.1) mm and (8.8±1.2) mm; all P<0.05], while LCI and WUUC/LUC were significantly higher than those of mild to moderate group [(41.8±8.6) mm and 0.94±0.16; all P<0.001]. LUC and endometrial nT₂-SI of mild to moderate group were significantly lower than those of the control group [ (32.4±5.1) vs (35.3±3.5) mm, 0.68±0.13 vs 0.80±0.12; all P<0.01]. LUC, WUUC, WLUC and endometrial nT₂-SI were significantly negatively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho:-0.794, -0.441, -0.471 and -0.316, respectively; all P<0.05), while LCI and WUUC/LUC were significantly positively correlated to the degree of the fibrotic repair secondary to endometrial injury (Spearman rho: 0.481 and 0.674, respectively; all P<0.05). LUC and WUUC/LUC showed high value in distinguishing severe group from the control group or mild to moderate group (all AUC>0.9, all P<0.001). Conclusion: As noninvasive and quantitative biomarkers, uterine morphological parameters and endometrial nT₂-SI could evaluate the degree of the fibrotic repair secondary to endometrial injury.

Extranodal natural killer/T-cell lymphoma (ENKTCL) is the subtype of non-Hodgkin lymphoma with high heterogeneity and invasiveness. Though most ENKTCL patients are present as early-stage at diagnosis, clinical prognosis significantly differs due to the limitations of clinical staging. Radiotherapy (RT) and chemotherapy (CT) are the first-line treatments for early ENKTCL patients. However, there is no consensus on the combined modalities of RT and CT, and their optimal strategy. With the continuous renewal of clinical staging and prognostic models, early-stage ENKTCL patients tend to accept risk-adapted treatment with proper stratification. In this review, the latest research progresses on clinical staging, prognostic models and treatment were retrospectively analyzed, aiming to provide references for clinical decision-making.

Objective To evaluate the methodological quality of clinical practice guidelines of rehabilitation using Appraisal of Guidelines for Research and Evaluation (AGREE) II.Methods Clinical practice guidelines of rehabilitation were searched in databases such as PubMed, EMBASE, Wanfang database, CNKI, China Biology Medicine disc and related websites from medlive.cn, National Institute for Health and Care Excellence, National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, World Health Organization, and Guidelines International Network from establishment to January 11, 2020. Two researchers reviewed literatures and assessed the methodological quality of the guidelines independently by using AGREE II; any disagreements needed to be discussed in a consensus meeting.Results A total of 84 guidelines were included in the study, with 67 foreign guidelines and 17 domestic guidelines. The average score rate for all the guidelines was 48.1%, in which 49.9% for the foreign guidelines and 40.7% for the domestic guidelines. In the six areas of AGREE II, the average score rate of the foreign guidelines was higher than that of domestic ones (|Z| > 2.034, P < 0.05), expect applicability; the average score rate of clarity and independence improved with the launch of AGREE Ⅱ ( Z > 2.130, P < 0.05). The average scores rate ranged from high to low followed as range and purpose (41.6%), clarity (39.9%), participants (24.5%), rigor (23.2%), independence (15.5%) and applicability (12.9%). Conclusion Clinical practice guidelines of rehabilitation is mainly of low quality by AGREE II. Guideline developers need to work after AGREE Ⅱ standard in the future.

This study is based on the data analysis of medicinal plant resources and diversity collected from the fourth Chinese traditional medicine resource survey( pilot). Through the analysis of relevant data from 33 census pioneer plots in Guizhou province( area),a total of 265 families,1 432 genera and 5 296 species of medicinal resources were reported,including algae,fungi,lichens,mosses,a total of 43 genera and 35 families,57,48 families,120 genera and 453 species of ferns,gymnosperms 11 families,22 genera and 61 species,167 families,1 243 genera and 4 721 species of angiosperms,4 genera and 4 families four medicinal animals.Compared with the data related to the third survey of traditional Chinese medicine resources,the number of ferns,gymnosperms and angiosperms in the fourth survey has increased far more than that of the third survey. From the regional distribution of medicinal resources,the composition of the genus,the type of life,and the location of the medicine,the richness of the medicinal plant resources in Guizhou province is not only reflected in many types,but also in the variety of medicinal resources. These studies provide a scientific basis for vigorously developing the Chinese herbal medicine industry and the sustainably using medicinal plant resources in Guizhou province.

Objective: To investigate the incidence, risk factors and survival of bronchiolitis obliterans syndrome (BOS) in patients who had undergone haplo-hematopoietic stem cell transplantation (haplo-HSCT) . Methods: This study retrospectively analyzed clinical data of 444 consecutive patients who underwent haplo-HSCT and survived at least 100 days after transplantation in the First Affiliated Hospital of Soochow University between January 2013 and December 2015. Results: By the end of follow-up on January 1, 2018, 25 patients (5.63%) had BOS (BOS group) . The median onset time of BOS was 448 (165-845) d post transplantation, the 1-year, 2-year and 3-year cumulative incidence of BOS was 1.6% (95%CI 1.5%-1.6%) , 4.8% (95%CI 4.7%-4.8%) and 5.8% (95%CI 5.7%-5.8%) , respectively. Among patients with chronic graft-versus-host disease (cGVHD) , the cumulative incidence at the same intervals was 2.8% (95%CI 2.7%-2.8%) , 9.5% (95%CI 9.4%-9.5%) and 11.5% (95%CI 11.4%-11.6%) , respectively. In the multivariate analysis, the risk factors for BOS were high-risk primary disease, Ⅱ-Ⅳ aGVHD and preceding cGVHD with other organs. The 3-year overall survival (OS) was lower among patients with than those without BOS, but the difference was not significant [71.8% (95%CI 53.9%-89.6%) vs 72.4% (95%CI 68.1%-76.7%) , P=0.400]. Overall 1-year, 3-year survival of patients with BOS from the time of diagnosis was 78.4% (95%CI 61.5%-95.3%) and 37.0% (95%CI 2.5%-71.5%) , respectively, significantly less than those without (93.9% and 89.3%, from day 448 after transplantation, respectively, P<0.001) . Furthermore, we found a significantly higher incidence of transplantation-related mortality (TRM) in patients with compared with patients without BOS (28.2% vs 10.9%, P<0.001) . The main risk factor for OS of BOS patients was the severity of pulmonary impairment at the time of diagnosis. Patients who developed severe BOS had a worse OS than those with moderate and mild BOS (P=0.049) . Conclusion: BOS is a severe pulmonary complication of haplo-HSCT. High-risk primary disease, Ⅱ-Ⅳ aGVHD and preceding cGVHD were independent risk factors for BOS. Patients who developed BOS had a worse OS than those without BOS. The main risk factor for OS of BOS patients was the severity of pulmonary impairment.

AIM:To investigate the regulatory effects of microRNA (miR)-130a on the biological characteris-tics of rat basilar arterial smooth muscle cells (BASMCs) and its underlying mechanisms. METHODS:The expression of miR-130a in rat BASMCs was measured by real-time PCR. After knockdown of miR-130a with inhibitor in the BASMCs, the cell viability, cell cycle distribution and apoptosis were detected by CCK-8 assay and flow cytometry. The expression of cell cycle- and apoptosis-related molecules, such as cyclin D1, cyclin-dependent kinase 2 (CDK2), p21, Bcl-2 and cleaved caspase-3/caspase-3 at protein levels was determined by Western blot. The growth arrest-specific homeobox protein ( Gax) expression at mRNA and protein levels was determined by real-time PCR and Western blot. RESULTS:Angioten-sionⅡ (AngⅡ) up-regulated the expression of miR-130a and down-regulated the expression of Gax (P<0. 05). Transfec-tion with miR-130a inhibitor partly reversed the increase in AngⅡ-induced cell viability and promoted the Gax expression. Furthermore, the early cell apoptotic rate was significantly increased after down-regulation of miR-130a (P<0.05), and the protein levels of cyclin D1, CDK2, Bcl-2 and p-Rb were significantly decreased, accompanied with the up-regulation of p21 and cleaved caspase-3 (P<0.05). CONCLUSION:Down-regulation of miR-130a restrains the viability and pro-motes the apoptosis of BASMCs by promoting Gax expression and regulating cell cycle- and apoptosis-related molecules, suggesting that miR-130a may be a potential therapeutic target of brain vascular remodeling during hypertension.

Aim To study the effect of butein on apop-tosis of PC12 cells induced by methylglyoxal (MG) and its mechanism. Methods Being pretreated with different concentrations of butein, PC12 cells were damaged by 1.5 mmol·L-1MG. Cell viability and cell toxicity were evaluated by MTT and LDH assay. Cell apoptosis and death were analyzed by PI and Ho-echst 33342. The antioxidant gene and proapoptotic gene expressions were determined by RT-PCR. The protein expression of p53 was detected by Western blot. Results Being pretreated with 2.5~10 μmol· L-1butein for 1 h significantly increased the cell via-bility,decreased LDH release,and protected from cell nuclei shrinkage, condensation and cleavage by MG. Meanwhile, butein increased the gene expression of SOD2, decreased the gene expression of proapoptotic genes p53 and caspase-9, and lowered the protein ex-pression of p53. Conclusion Butein can protect ap-optosis of PC12 cells from MG in a dose-dependent manner,which is linked with antioxidation and inhibi-ting p53 and caspase-9 gene expression.
