RESUMEN

PURPOSE: Benign prostatic hyperplasia (BPH) describes common noncancerous prostate enlargement. BPH is usually associated with lower urinary tract symptoms and an increased risk of cerebrovascular diseases, such as stroke and its recurrence. White matter hyperintensities (WMHs), markers of cerebral injury, increase the risk of stroke, cognitive impairment, dementia, and death. The relationship between BPH and WMHs remains unclear. This study aimed to determine the association between BPH and WMHs. METHODS: A total of 788 male patients from the First Affiliated Hospital of Kunming Medical University from July 2019 to September 2021 were enrolled in this cross-sectional study. BPH was assessed by abdominal ultrasound, and three independent neuroradiologists rated the presence or absence of WMHs. Multiple imputations of chained equations were used to handle missing data. Logistic regression was used to assess the relationship between BPH and WMHs. RESULTS: Patients with BPH presented an increased risk of WMHs with a crude odds ratio (OR) of 2.76 (95% CI, 2.02-3.79) and an adjusted OR of 1.75 (95% CI, 1.24-2.48) after controlling for potential confounding factors in the multivariate logistic regression. CONCLUSION: We found that BPH was closely associated with WMHs in male Chinese individuals.

RESUMEN

As per the theory of traditional Chinese medicine (TCM), the liver and kidney dysfunction are important pathogenies for premature ovarian failure (POF). POF is a common gynecological disease that reduced the pregnancy rate. Electro-acupuncture (EA) is a useful non-pharmaceutical therapy that supposedly regulates the function of the liver and kidney in the treatment of POF with TCM. However, the underlying mechanism of EA in the treatment of POF has not been adequately studied through metabonomics with reference to the theory of TCM. Accordingly, we investigated the effect of EA on the liver and kidney metabolites in POF mice through metabolomics. POF mice were established via intraperitoneal injection of cisplatin. Both Sanyinjiao (SP6) and Guanyuan (CV4) were stimulated by EA for 3 weeks. The biological samples (including the serum and the ovary, liver, and kidney tissues) were evaluated by histopathology, molecular biology, and hydrogen-1 nuclear magnetic resonance (1HNMR)-based metabolomics to assess the efficacy of EA. 1HNMR data were analyzed by the orthogonal partial least squares discriminant analysis (OPLS-DA). The results revealed that EA was beneficial to ovarian function and the menstrual cycle of POF. Both the energy metabolism and neurotransmitter metabolism in the liver and kidney were regulated by EA. Notably, EA played an important role in regulating energy-related metabolism in the kidney, and the better effect of neurotransmitter-related metabolism in the liver was regulated by EA. These findings indicated that the ovarian functions could be improved and the metabolic disorder of the liver and kidney caused by POF could be regulated by EA. Our study results thus suggested that the EA therapy, based on the results for the liver and kidney, were related to POF in TCM, as preliminarily confirmed through metabolomics.

RESUMEN

BACKGROUND: Diabetic microvascular complications, including diabetic kidney disease (DKD), retinopathy (DR), and neuropathy (DN), were major causes of morbidity and mortality in diabetic patients worldwide. It has been suggested that urinary albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) were not the only indicators of renal function impairment in DKD and that they were also associated with diabetic peripheral neuropathy (DPN) which might affect nerve conduction velocity (NCV). As 30-40% of DPN patients had no subjective symptoms, while current perception threshold (CPT) could detect sensory nerve damage at an early stage. As a result, we aimed to investigate correlation between UACR, eGFR and CPT in DKD patients. METHODS: A total of 273 DKD patients from the First Affiliated Hospital of Kunming Medical University from January 2018 to June 2020 were enrolled to complete the CPT test. CPT values of the bilateral median nerve and superficial and deep peroneal nerves at 2000 Hz, 250 Hz, and 5 Hz were collected. RESULTS: In normoesthesia and hypaesthesia patients with DKD, MDRD-eGFR correlated negatively with TC (r = -0.135, P = 0.037), left superficial peroneal and deep peroneal nerve 2000 Hz CPT (r = -0.205, P = 0.001) and right superficial peroneal and deep peroneal nerve 2000 Hz CPT (r = -0.154, P = 0.017). Besides, left and right superficial peroneal and deep peroneal nerve 2000 Hz CPT correlated with CKD-EPI-eGFR and UACR. Multivariate logistic regression analysis found left superficial peroneal and deep peroneal nerve 2000 Hz CPT was independently associated with both MDRD-eGFR and CKD-EPI-eGFR. CONCLUSION: Decreased MDRD-eGFR and CKD-EPI-eGFR were expected to be a predictor of peripheral nerve injury in normoesthesia and hypaesthesia patients with DKD.

RESUMEN

Growing evidence showed that the gut microbiota was associated with premature ovarian failure (POF). Many clinical types of research had shown that electroacupuncture was effective in the treatment of POF. However, there was little research on regulating the gut microbiome of POF mice by electroacupuncture. Therefore, this study attempted to verify whether electroacupuncture could regulate the gut microbiome in POF mice. POF mice were established by being injected intraperitoneally with cisplatin (2 mg/kg) for 2 weeks. Guanyuan (CV4) and Sanyinjiao (SP6) were selected in the electroacupuncture-at-the-acupoints group (EA group). Nonacupoints around CV4 and SP6 were selected in the electroacupuncture-at-the-nonacupoints group (EN group). The EA group and EN group were treated for 3 weeks. The ovarian function was evaluated by histopathological and molecular assays. Meanwhile, the gut microbiome of all mice was detected by 16S rDNA sequencing. The results showed that EA could restore the estrous cycle and reduce the number of atresia follicles in POF mice. The levels of serum follicle-stimulating hormone and luteinizing hormone were decreased by EA. As well, the levels of serum estradiol, anti-Mullerian hormone, and ß-glucuronidase were increased by EA. The relative expressions of PI3K, AKT, and mTOR were increased to promote the proliferation of ovarian cells in the EA group. According to the results of 16S rDNA sequencing, the abundance and diversity of the gut microbiome could be regulated by EA. The relative abundance of beneficial bacteria was increased by EA. The KEGG pathway analysis showed that the gut microbiome associated with the estrogen signaling pathway, oocyte maturation, and PI3K-AKT signaling pathway was regulated by EA.

RESUMEN

Lung cancer is the leading cause of cancer death. Pyronaridine, a synthetic drug of artemisinin, has been used in China for over 30 years for the treatment of malaria, but its effect on non-small cell lung cancer (NSCLC) cells is rarely reported. In this study, we determined the efficacy of pyronaridine in four different NSCLC cell lines and explored its mechanism in H1975. The data showed that pyronaridine could upregulate the expression of TNF-related apoptosis-inducing ligand (TRAIL)-mediated death receptor 5 to promote cellular apoptosis. Meanwhile, the JNK (c-Jun N-terminal kinase) level was detected to be significantly increased after treating with pyronaridine. We used JNK inhibitor and found that it could partially inhibit cell apoptosis. The results showed that epidermal growth factor receptor (EGFR), PI3K, and AKT were downregulated after the treatment of pyronaridine. In summary, pyronaridine can selectively kill NSCLC by regulating TRAIL-mediated apoptosis and downregulating the protein level of EGFR. It is a promising anticancer drug for NSCLC.

RESUMEN

Menopausal syndrome (MPS) is a common gynecological disorder around the time of menopause, and hormone therapy (HT) is the first-line treatment for it. However, HT is prone to cause adverse reactions in MPS patients treated with HT. Acupuncture is a popular non-pharmaceutical therapy for MPS, but the differences in the efficacy and safety between acupuncture and HT remain unclear. The purpose of this evidence-based study is to address this issue. Five databases were searched for potentially eligible RCTs. All RCTs comparing acupuncture with HT in the treatment of MPS were included in this study. The clinical effective rate was the primary outcome. Kupperman index, serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E[Formula: see text], and side effects were the secondary outcomes. A total of 15 RCTs recruiting 1376 MPS patients were included. Results of meta-analysis showed that compared with HT, acupuncture significantly improved clinical effective rate (RR = 1.09, 95% CI 1.03 to 1.16, [Formula: see text] = 0.005), decreased the Kupperman index (WMD = -2.55, 95% CI = -2.93 to -2.17, [Formula: see text] < 0.00001) and the incidence of side effects (RR = 0.14, 95% CI = 0.06-0.32, [Formula: see text] < 0.00001). There were no statistically significant differences in serum FSH (WMD = -1.36, 95% CI = -3.25-0.53, [Formula: see text] = 0.16), E2(WMD = -1.11, 95% CI = -2.59-0.37, [Formula: see text] = 0.14), or LH (WMD = -1.87, 95% CI = -4.58-0.83, [Formula: see text] = 0.17) between the acupuncture and HT groups. Based on the current evidence, manual acupuncture is safer and more effective than HT and is recommended for the treatment of MPS, but the evidence for the efficacy of other types of acupuncture is inconclusive.

RESUMEN

BACKGROUND: Gastric mucosal lesion (GML) is the initiating pathological process in many refractory gastric diseases. And moxibustion is an increasingly popular alternative therapy that prevents and treats diseases. However, there are few published reports about developing pathology of GML and therapeutic mechanism of moxibustion treatment on GML. In this study, we investigated pathology of GML and therapeutic mechanism of moxibustion treatment on GML. METHODS: The male Sprague-Dawley (SD) rats were induced by intragastric administration of 75% ethanol after fasting for 24 h and treated by moxibustion at Zusanli (ST36) and Liangmen (ST21) for 1 day, 4 days or 7 days. Then we applied 1H NMR-based metabolomics to dynamic analysis of metabolic profiles in biological samples (stomach, cerebral cortex and medulla). And the conventional histopathological examinations as well as metabolic pathways assays were also performed. RESULTS: Moxibustion intervention showed a beneficial effect on GML by modulating comprehensive metabolic alterations caused by GML, including energy metabolism, membrane metabolism, cellular active and neurotransmitters function. CONCLUSIONS: Moxibustion can effectively treat gastric mucosal damage and effectively regulate the concentration of some related differential metabolites to maintain the stability of the metabolic pathway.

RESUMEN

Gastric ulcer (GU), a common digestive disease, has a high incidence and seriously endangers health of human. According to the previous studies, it has been proved that electroacupuncture at acupoints of stomach meridian had a good effect on GU. However, there are few published studies on metabolic response in gastric ulcer (GU) rats with electroacupuncture treatment. Herein, we observed the metabolic profiles in biological samples (stomach, liver, and kidney) of GU rats with electroacupuncture treatment by 1H NMR metabolomics combined with pathological examination. The male SD rats were induced by intragastric administration of 70% ethanol after fasting for 24 hours and treated by electroacupuncture at Zusanli (ST36) and Liangmen (ST21) for 1 day, 4 days, or 7 days, respectively. And the conventional histopathological examinations as well as metabolic pathways assays were also performed. We found that GU rats were basically cured after electroacupuncture treatment for 4 days and had a complete recovery after electroacupuncture treatment for 7 days by being modulated comprehensive metabolic changes, involved in the function of neurotransmitters, energy metabolism, cells metabolism, antioxidation, tissue repairing, and other metabolic pathways. These findings may be helpful to facilitate the mechanism elucidating of electroacupuncture treatment on GU.

RESUMEN

In Traditional Chinese Medicine (TCM), moxibustion had been used for thousands of years. Many clinical case reports and scientific studies had proved that moxibustion had a good effect in treating acute gastric ulcer (AGU). Some studies had shown that the relative content and species of bacteria in the intestinal would be changed when gastric mucosal injury happened. However, there was little research on the effect of intestinal microbiome with AGU rats that were treating by moxibustion. This study is aimed at analyzing the effect of fecal microbiome in rats with AGU by the 16S rDNA sequencing technology. Male SD rats were established by orally feeding once with 70% ethanol at 4 ml/kg except the control group, then treated by moxibustion in the stomach meridian group ("Liangmen," "Zusanli") and the gallbladder meridian group ("Riyue," "Yanglingquan") for 5 days. The 16S rDNA sequencing technology analysis of feces combined with histopathological methods and molecular biological detection methods was used to evaluate the therapeutic mechanism of moxibustion on AGU. AGU brought cause changes in the number and species of intestinal bacteria. Moxibustion on stomach meridian group could reduce the area of gastric mucosal injury and regulate the relative content of GAS and EGF. Moreover, moxibustion on the stomach meridian group could increase the relative content and species of beneficial bacteria in the intestine of rats with AGU. The relative abundance of intestinal probiotics was significantly upregulated in Alphaproteobacteria, Actinomycetales, and Bacillales. In addition, moxibustion might promote the repair of gastric mucosal injury by increasing the number and species of beneficial bacteria in the intestine.

RESUMEN

Acupuncture and moxibustion proved to be very effective in chronic atrophic gastritis (CAG). According to the Chinese traditional medicine theory, chronic diseases have an influence on the function of liver and kidney. However, there is little research to demonstrate this theory. This study is aimed at assessing the 1H NMR-based metabolic profiling in liver and kidney of CAG rats and comparing the difference between electroacupuncture and moxibustion treatment. Male SD rats were subjected to CAG modeling by intragastric administration of mixture of 2% sodium salicylate and 30% alcohol coupled with compulsive sporting and irregular fasting for 12 weeks and then treated by electroacupuncture or moxibustion at Liangmen (ST 21) and Zusanli (ST 36) acupoints for 2 weeks. A 1H NMR analysis of liver and kidney samples along with histopathological examination and molecular biological assay was employed to assess and compare the therapeutic effects of electroacupuncture and moxibustion. CAG brought characterization of metabolomic signatures in liver and kidney of rats. Both electroacupuncture and moxibustion treatment were found to normalize the CAG-induced changes by restoring energy metabolism, neurotransmitter metabolism, antioxidation metabolism, and other metabolism, while the moxibustion treatment reversed more metabolites related to energy metabolism in liver than electroacupuncture treatment. CAG did have influence on liver and kidney of rats. Both of these treatments had good effects on CAG by reversing the CAG-induced perturbation in liver and kidney. For regulating the energy metabolism in liver, the moxibustion played more important role than electroacupuncture treatment.

RESUMEN

Some studies have proved that both acupuncture and moxibustion are very effective for the treatment of CAG. However, little is known about therapeutic mechanism of electro-acupuncture and moxibustion on CAG as well as the difference between them. On the other hand, metabolomics is a 'top-down' approach to understand metabolic changes of organisms caused by disease or interventions in holistic context, which consists with the holistic thinking of electro-acupuncture and moxibustion treatment. In this study, the difference of therapeutic mechanism between electro-acupuncture and moxibustion on CAG rats was investigated by a 1H NMR-based metabolomics analysis of multiple biological samples (serum, stomach, cerebral cortex and medulla) coupled with pathological examination and molecular biological assay. For all sample types, both electro-acupuncture and moxibustion intervention showed beneficial effects by restoring many CAG-induced metabolic changes involved in membrane metabolism, energy metabolism and function of neurotransmitters. Notably, the moxibustion played an important role in CAG treatment mainly by regulating energy metabolism in serum, while main acting site of electro-acupuncture treatment was nervous system in stomach and brain. These findings are helpful to facilitate the therapeutic mechanism elucidating of electro-acupuncture and moxibustion on CAG rats. Metabolomics is promising in mechanisms study for traditional Chinese medicine (TCM).
