Through evidence mapping, this paper systematically summarized the research evidence on the use of traditional Chinese medicine(TCM) in treating renal anemia, displaying the distribution of evidence in this field. A systematic search was conducted across databases, including CNKI, Wanfang, VIP, SinoMed, Springner, PubMed, Engineering Village, and Web of Science, targeting studies published up to June 30, 2024. The research evidence was summarized and displayed through a combination of graphs, tables, and text. A total of 264 interventional studies, 37 observational studies, and 7 systematic reviews were included. The annual publication volumes related to TCM treatment in renal anemia showed an overall upward trend, with most studies involving sample sizes between 60 and 120 participants(224 articles, 74.42%). Intervention measures were categorized into 21 types, with oral TCM decoctions being the most common medicine(171 times, 56.81%). The use of self-made prescriptions was the most common TCM intervention method. The intervention duration was mainly between 8 weeks and 3 months(239 articles, 79.40%). The most frequently reported TCM syndrome was spleen and kidney Qi deficiency. The top 2 outcome indicators were the anemia indicators and renal injury/renal function markers. However, several issues were identified in these studies, such as insufficient attention to the sources, social/geographical information, and temporal continuity of research subjects in observational research. Randomized controlled trials mostly had a high risk of bias, mainly due to issues such as randomization bias, blinding bias, and failure to register research protocols. The methodology quality of systematic reviews was generally low, mainly due to inadequate inclusion of literature, failure to specify funding sources, and lack of pre-registrations. While the report quality of systematic review was acceptable, there were significant gaps in the reporting of protocols, registration, and funds. The results show that these issues affect the quality of research and the reliability of findings on TCM in treating renal anemia, underscoring the need to address them to conduct higher-quality research and provide more reliable medical evidence for TCM in treating renal anemia.

Purpose: We aimed to investigate the mechanism of phenotypic transformation of corporal cavernosum smooth muscle cells (CCSMCs) under hypoxic conditions in vitro. Materials and Methods: In this study, a hypoxia model was established using cobalt chloride (CoCl2). CCSMCs were treated with different concentrations of CoCl2 for varying time periods, and cell viability was assessed. Hypoxia-inducible factor-1α (HIF-1α), myocardin (Myocd) and phenotypic markers were detected in the CCSMCs. We also transfected the CCSMCs with si-HIF-1α and Ad-Myocd and evaluated the effects on phenotypic modulation of CCSMCs and the relationship between HIF-1α and Myocd was evaluated. Results: CoCl2 inhibited the viability of CCSMCs in a dose- and time-dependent manner, and treatment with 300 µM CoCl2 for 48 hours were the optimal conditions for establishing the hypoxia model. The results showed increased expression levels of HIF-1α and osteopontin and decreased Myocd, alpha-smooth muscle actin, and calponin levels in CCSMCs under hypoxia. HIF-1α knockdown reversed hypoxia-induced phenotypic transformation with elevated Myocd expression. Overexpression of Myocd also reversed the effect of hypoxia on the phenotypic switch, but did not affect HIF-1α expression. Conclusions Our findings showed that HIF-1α was involved in the effect of hypoxia induced by CoCl2 on CCSMC phenotypic modulation, and Myocd overexpression could inhibit this process. Thus, Myocd might be a potential therapeutic target for erectile dysfunction under hypoxia or HIF-1α activation.

OBJECTIVE: To investigate the association of atrial fibrillation (AF) with hemorrhagic transformation (HT) in patients with ischemic stroke treated by intravenous thrombolysis. METHODS: Clinical data of 3272 patients treated by intravenous thrombolysis from 71 hospitals in Zhejiang Province during June 2017 and December 2018 were retrospectively reviewed. Intracranial HT was defined as intracranial hemorrhage suggested by imaging examination 24 hours after intravenous thrombolysis. Patients were dichotomized into HT group (=533) and non-HT group (=2739). The association of AF and HT was analyzed by univariate analysis and binary logistic regression. RESULTS: Compared with the non-HT group, the HT group were older, had longer onset to needle time (ONT), higher baseline National Institute of Health Stroke Scale (NIHSS) score, higher baseline glucose level, and higher AF rate (<0.05 or <0.01). Binary logistic regression analysis revealed that AF was independently associated with HT (=2.527, 95%:2.030-3.146, <0.01). CONCLUSIONS AF is independently associated with the occurrence of HT in ischemic stroke patients treated with intravenous thrombolysis.

OBJECTIVETo explore the characteristics of cell apoptosis and proliferation of corpus cavernosum smooth muscle (CCSM) cells in diabetic rats.

METHODSFrom a SD rat model of diabetes induced by a single dose of streptozotocin, CCSM cells were isolated for primary culture and identified using immunocytochemical assays for SMα-actin. The proliferation of CCSM cells was evaluated by WST-1 assay, and flow cytometry was used to detect the cells apoptosis. Real-time fluorescence quantitative RT-PCR (qRT-PCR) was used to analyze the relative expression of proliferation cell nucleus antigen (PCNA) and caspase-3 mRNA.

RESULTSThe proliferation rate of the primarily cultured CCSM cells from diabetic rats was significantly decreased and the apoptosis rate significantly increased compared with those of the cells from the control rats. The expression of PCNA mRNA was significantly lowered while caspase-3 mRNA significantly increased in the corpus cavernosum of the diabetic rats (P<0.001).

CONCLUSIONIn rats with persisted hyperglycemia, a higher apoptosis rate and a lower proliferation rate both contribute to the reduction of CCSM cells.
