RESUMEN
Purpose: Diastasis recti abdominis (DRA) is a condition in which the linea alba is stretched and widened, and the abdominal muscles are separated from each other. DRA typically occurs in pregnant and postpartum women. We aimed to determine the risk factors and patient-reported outcomes (PROs) of DRA in Chinese postpartum women. Methods: This observational study was conducted in Hangzhou Hospital of Traditional Chinese Medicine, and involved 534 women who filled out the following risk-factor and PRO questionnaires: SF-MPQ-2, SF-ICIQ, LDQ, EPDS, MBIS, HerQles, and SF-36 (all Chinese versions). The inter-recti distance was measured by palpation. Statistical analyses were performed using SPSS v25.0 software and the Mann-Whitney U-test, chi-square test, binary logistic regression analysis (for risk factors of DRA), and the Kendall and Spearman tests (for correlation analysis). Results: After childbirth, 78.1% (417/534) of the enrolled women had DRA. Abdominal surgery (P = 0.002), number of pregnancies (P = 0.035), parity (P = 0.012), number of births (P = 0.02), fetal birth weight (P = 0.014), and waist-to-hip ratio in the supine position (P = 0.045) significantly differed between the DRA and non-DRA groups. Caesarean delivery was an independent risk factor for DRA. The PROs were significantly worse in the DRA group than in the non-DRA group. Conclusion: Caesarean delivery was an independent risk factor for DRA. Women with DRA are more likely to have limited physical activity or function after childbirth, lower self-confidence, and a decreased quality of life.
RESUMEN
Objective: To study the association of H. pylori infection with colorectal adenomas. Methods: Web searches of PubMed, Embase, and Scopus databases for randomized controlled trials, class-experimental studies, and cohort studies on the association between H. pylori and colorectal adenomas were performed from May 2000 to May 2023. Literature was screened based on inclusion and exclusion criteria, data were extracted and evaluated for quality, and statistical analyses were performed using RevMan 5.2 software. Results: A total of 15 studies were included, and meta-analysis showed a statistically significant difference between colorectal neoplastic polyp cases in the H. pylori-positive and H. pylori-negative groups [OR=1.80, 95%CI: (1.31, 2.47), P < .01, I2 = 95%]. Analysis based on subgroups of different H. pylori detection methods showed that the correlation between H. pylori infection and colorectal polyp incidence is not affected by their detection methods, with serological detection subgroup: [OR=0.13, 95%CI: (0.05, 0.21), P < .01, I2 = 88%], and non-serological detection subgroup: [OR=0.13, 95%CI: (0.04, 0.22), P < .01, I2 = 95%]. Subgroup analysis of pathological types showed that H. pylori infection is not significantly associated with the development of non-neoplastic polyps [OR=1.47, 95%CI: 0.98-2.22, P = .06], whereas it is correlated with the development of neoplastic polyps [95%CI: 1.69-3.22, P < .01]. In the subgroup analysis of geographic differences in the population, H. pylori infection was correlated with the development of colorectal polyps in different geographic populations (P < .01). Conclusion: H. pylori infection is a risk factor for colorectal polyp neoplasia, its infection is associated with colorectal neoplasia, and the correlation is not affected by the different methods of H. pylori detection and the different geographic regions of the population.
RESUMEN
OBJECTIVE: Salvia miltiorrhiza (SM) is a traditional Chinese medicine used clinically to treat cardiovascular diseases, including atherosclerosis and myocardial infarction. Its therapeutic effect has been confirmed by many clinical and pharmacological studies. However, the optimal formulation of active ingredients in SM for treating cardiovascular diseases remains unclear. In this study, we determined the ratio of the optimal compatibility of SM ingredients DSS, Sal-A, Sal-B, and PAL (SABP)with a uniform and orthogonal optimized experimental design. In addition, we determined the anti-oxidation effect of SABP using Adventitial Fibroblasts (AFs). METHODS: By using a combination of uniform and orthogonal designs, we determined the optimal formulation of aqueous extract from SM. MTT assay was used to determine the inhibitory effects of these 4 components of SM on the AFs, which were isolated and cultured from the aorta. The reactive oxygen species (ROS) production in AFs was compared before and after SABP treatment. RESULTS: The optimal formulation of these 4 aqueous extracts from SM were 150 : 7 : 300 : 500, and their concentrations were S(1.5×10-4 mol/L), A(7×10-6 mol/L), B(3×10-4 mol/L), and P(5×10-4 mol/L). There were some synergies between these 4 components. Moreover, SABP decreased ROS production in AFs. CONCLUSION: These findings suggest that SABP inhibits the proliferation and oxidation stress in AFs. The present study provides new evidence that the efficacy and function generated from the optimal formulation of active ingredients in SM are better than lyophilized powder of SM.

Alzheimer's disease (AD), the most common cause of dementia, is a neurodegenerative disorder characterized by amyloid plaque accumulations, intracellular tangles and neuronal loss in certain brain regions. It has been shown that a disturbance of normal iron metabolism contributes to the pathophysiology of AD. However, the mechanism underlying abnormal iron load in the brain of AD patients is unclear. The frontal cortex, an important brain structure for executive function, is one of the regions affected by AD. We investigated the beneficial effects of active compounds of Epimedium, Astragaoside and Puerarin on iron metabolism in the frontal cortex of six-month-old APPswe/PS1ΔE9 (APP/PS1) double transgenic mouse, a model of AD. Treatment with the active compounds reduced cognitive and memory deficits and damaged cell ultrastructure in APP/PS1 mice. These beneficial effects were associated with changes in expression levels of iron metabolism proteins in the frontal cortex, including divalent metal transporter with iron response element (DMT1-with IRE), divalent metal transporter without iron response element (DMT1-without IRE), transferrin (TF) and transferring receptor 1 (TfR1); three release proteins including the exporter ferroportin 1 (Fpn1), ceruloplasmin (CP) and hephaestin (HEPH), one increased storage iron protein ferritin and one iron regulating hormone hepcidin. These findings suggest that the active compounds improve cognition and memory in brain neurodegenerative disorders and these beneficial effects are associated with reduced impairment of iron metabolism. This study may provide a new strategy for developing novel drugs to treat AD.

BACKGROUND: Graft-versus-host disease (GVHD) is a systemic disease, and skin is often one of the target organs. An atopic dermatitis (AD)-like presentation has never to our knowledge been reported. OBJECTIVE: We sought to describe an AD-like presentation of cutaneous GVHD. METHODS: Data on 11 patients with an AD-like presentation of GVHD were collected. The clinical and laboratory findings were retrospectively studied. RESULTS: All 11 patients developed skin lesions after hematopoietic stem-cell transplantation. The skin lesions occurred between 2 to 12 months after transplantation. Eight patients received their transplant from a first-degree family member; 3 received their transplant from an unrelated donor. The skin lesions were pruritic and suggestive of AD, whereas the histology showed features of AD and GVHD. The lesions responded to topical and systemic anti-inflammatory and immunosuppressive therapy and phototherapy. LIMITATIONS: The number of patients is small and the study is retrospective. CONCLUSIONS: AD-like GVHD might represent a novel form of chronic cutaneous GVHD and responds well to treatment.
