RESUMEN
OBJECTIVE: To investiage the possible mechanism underlying the effect of the Jianpi Qutan Fang (, JPQT) on Atherosclerosis (AS) which is the main pathological process of most cardiovascular diseases that affect millions of adults worldwide. METHODS: In the present study, rats were fed with a high-fat-diet (HFD) with vitamin D3 for 16 weeks and were orally administered atorvastatin treatment and different doses of JPQT. Histopathological changes and ultrastructural changes in the aorta were evaluated through hematoxylin-eosin staining and transmission electron microscopy (TEM), respectively. Suppressor of cytokine signaling 1 (SOCS1)/Janus kinase 1 (JAK1)/ signal transducer and activator of transcription 1 (STAT1) signaling pathways were detected through Western blotting. RESULTS: JPQT treatment decreased the lipid levels of triglyceride, low-density lipoprotein, and cholesterol, the inflammatory cytokine levels of interleukin 1 beta (IL-1ß), IL-6 and IL-8 in rat serum, but increased high-density lipoprotein and IL-10 serum levels. JPQT treatment ameliorated pathological changes in the aorta of AS model rats. Moreover, JPQT upregulated SOCS1 protein expression and down-regulated phosphorylated protein expression levels of p-JAK1 and p-STAT1. CONCLUSION: These results suggest that JPQT induces anti-atherosclerosis effects through anti-inflammatory and inhibiting JAK/STAT signaling pathways in HFD fed rats.

Endophytic fungi play important roles in regulating plant growth and development and usually used as a promising strategy to enhance the biosynthesis of host valuable secondary metabolite, but the underlying growth-promoting mechanisms are only partly understood. In this study, the wild-type Arabidopsis thaliana seedlings co-cultured with fungal endophyte Epichloë bromicola showed auxin (IAA)-stimulated phenotypes, and the growth-promoting effects caused by E. bromicola were further verified by the experiments of spatially separated co-culture and fungal extract treatment. IAA was detected and identified in the extract of E. bromicola culture by LC-HRMS/MS, whereas 2,3-butanediol was confirmed to be the predominant volatile active compound in the diethyl ether and ethyl acetate extracts by GC-MS. Further study observed that IAA-related genes including synthesis key enzyme genes (CYP79B2, CYP79B3, NIT1, TAA1 and YUCCA1) and controlling polar transport genes (AUX1, BIG, EIR1, AXR3 and ARF1), were highly expressed at different periods after E. bromicola inoculation. More importantly, the introduction of fungal endophyte E. bromicola could effectively promote the growth and accumulation of coixol in Coix under soil conditions. Our study showed that endophytic fungus E. bromicola might be considered as a potential inoculant for improving medicinal plant growth.

Objective:To compare the efficacies of 3D printed guide plate assisted positioning and C-arm X-ray machine fluoroscopic positioning for femoral tunnel reconstruction of medial patellofemoral ligament in treating recurrent patellofemoral dislocation.Methods:A retrospective cohort study was performed on the clinical data of 60 patients with recurrent patellar dislocation admitted to the First Affiliated Hospital of Kunming Medical University from January 2018 to December 2022. The patients included 29 males and 31 females, with age range of 14-40 years [(28.6±7.6)years]. The 3D printed guide plate was used to locate the femoral tunnel in 30 patients for medial patellofemoral ligament reconstruction (3D guide group), and C-arm X-ray machine was used for another 30 patients (conventional group). (1) CT data of the knee joint were collected before surgery and at 7 days after surgery. Mimics 19.0 software was introduced to measure the distance between the center of femoral tunnel and Sch?ttle point after surgery. (2) Knee Lysholm score and Kujala score were used to evaluate the knee function before and at 3, 6, 9 and 12 months after surgery. (3) At the same time points, Opti-Knee TM 3D knee kinematics analysis system was used to collect the forward and backward displacement, up and down displacement, internal and external displacement, internal and external flipping angle, internal and external rotation angle, and flexion and extension angle of the affected knee joint. The range of each freedom degree was calculated and 6 freedom degree items of 30 healthy people were subjected to knee kinematics analysis. Results:All patients were followed up for 12-15 months [(12.3±0.7)months]. (1) The distance between the center of femoral tunnel and Sch?ttle point in the 3D guide group was (5.5±2.3)mm, smaller than that in the conventional group [(7.6±2.5)mm] ( P<0.01). (2) The Lysholm score and Kujala score of the 3D guide group and conventional gruop gradually increased after surgery (all P<0.01). There were no significant differences in the Lysholm score or Kujala score between the 3D guide group and conventional gruop before surgery and at 12 months after surgery (all P>0.05). At 3, 6 and 9 months after surgery, the Lysholm score of the 3D guide group [(70.4±4.5)points, (86.4±3.1)points, (91.2±3.2)points] and Kujala score [(74.2±5.3)points, (80.9±3.5)points, (85.2±3.2)points] were higher than those of the conventional group [Lysholm score: (67.3±5.2)points, (81.8±2.5)points, (86.2±1.9)points; Kujala score: (69.8±5.2)points, (77.6±2.1)points, (82.7±2.6)points] ( P<0.05 or 0.01). (3) Before surgery, the forward and backward displacement in the 3D guide group and conventional group [(0.6±0.1)cm, (0.6±0.2)cm], up and down displacement [(0.5±0.1)cm, (0.6±0.0)cm], internal and external displacement [(0.7±0.1)cm, (0.6±0.2)cm], and flexion and extension angle [(50.6±10.3)°, (51.6±8.5)°] were less than those in the healthy controls [(1.6±0.3)cm, (1.7±0.5)cm, (1.0±0.4)cm, (63.2±5.1)°] (all P<0.05), while the internal and external flipping angle [(17.5±4.0)°, (17.1±3.8)°] and internal and external rotation angle [(17.9±1.9)°, (17.5±1.5)°] were greater than those in the healthy controls [(11.8±3.6)°, (15.8±4.9)°] (all P<0.05). At other time points, the results of front and back displacement, up and down displacement, internal and external displacement, internal and external rotation angle in the 3D guide group and conventional group were not significantly different compared with the healthy controls (all P>0.05). The flexion and extension angle in the 3D guide group and conventional gruop were smaller than those in the healthy controls at 3 months after surgery (all P<0.05). At 6 and 9 months after surgery, the flexion and extension angle in the conventional group [(55.0±3.7)°, (57.7±4.8)°] were smaller than those in the healthy controls [(63.2±5.1)°, (63.2±5.1)°] (all P<0.05), but no significant difference was found between the 3D guide group [(61.0±4.8)°, (61.8±4.9)°] and the healthy controls (all P>0.05). The flexion and extension angle in the 3D guide group and conventional gruop was similar with that in the healthy controls at 12 months after surgery (all P>0.05). Conclusions:Compared with the C-arm X-ray machine, the 3D printed guide plate assisted positioning of femoral tunnel is more simple and accurate for the medial patellofemoral ligament reconstruction in treating recurrent patellofemoral dislocation, together with better early knee function recovery, better satisfaction of the patients, and better and faster restoration of the flexion and extension angle of knee joint kinematic function.
RESUMEN
ObjectiveTo investigate the protective effect of modified Huangqi Guizhi Wuwutang (MHGW) on endoplasmic reticulum stress in the sciatic nerve of diabetes rats based on the pathways of inositol-requiring enzyme 1α (IRE1α) and CCAAT/enhancer-binding protein homologous protein (CHOP). MethodSixty rats were fed on a high-sugar and high-fat diet for six weeks, followed by intraperitoneal injection of streptozotocin at a dose of 35 mg·kg-1. Random blood glucose levels were measured three days later and rats with a sustained blood glucose level ≥ 16.7 mmol·L-1 were included in study (n=48). The rats were randomly divided into a model group, an α-lipoic acid group (0.026 8 g·kg-1·d-1), a high-dose MHGW group (2.5 g·kg-1·d-1), and a low-dose MHGW group (1.25 g·kg-1·d-1). Another 10 rats were assigned to the normal group. The intervention lasted for 16 weeks. After 16 weeks, the sciatic nerve structure of the rats in each group was observed under light microscopy using Luxol fast blue (LFB) staining. Transmission electron microscopy was used to observe the ultrastructure of the sciatic nerve. Chemiluminescence method was employed to measure the serum reactive oxygen species (ROS) levels. Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to evaluate the expression of p-IRE1α protein, IRE1α mRNA, CHOP protein, and CHOP mRNA in the sciatic nerve of the rats. ResultCompared with the normal group, the model group showed elevated serum ROS levels (P<0.01). In contrast, the serum ROS levels were significantly reduced in the treatment groups compared with those in the model group (P<0.01). The sciatic nerve of the model group showed pathological changes compared with that in the normal group, while the treatment groups exhibited improvement in sciatic nerve pathology compared with the model group. The protein expression of p-IRE1α and CHOP in the sciatic nerve significantly increased in the model group as compared with that in the normal group (P<0.01). However, the treatment groups showed a significant decrease in the protein expression of p-IRE1α and CHOP in the sciatic nerve compared with the model group (P<0.05, P<0.01). Furthermore, compared with the normal group, the model group showed upregulated mRNA expression of IRE1α and CHOP in the sciatic nerve (P<0.01), while the treatment groups exhibited a significant decrease in the mRNA expression of IRE1α and CHOP compared with the model group (P<0.01). ConclusionMHGW can alleviate endoplasmic reticulum stress-induced cell apoptosis and improve the structure and function of the sciatic nerve in diabetes rats by inhibiting the expression of IRE1α/CHOP pathway-related proteins and mRNA, thereby preventing and treating peripheral neuropathy in diabetes.
RESUMEN
Obesity is a chronic, recurrent, and progressive metabolic disorder characterized by the abnormal or excessive accumulation of body fat caused by multiple factors such as genetics, dietary structure, lifestyle and behavior, psychology, environment, and society, leading to an energy surplus. Obesity is a major risk factor that increases the risk of developing various chronic diseases, including type 2 diabetes, hypertension, cardiovascular diseases, stroke, and certain malignancies. The global incidence of obesity is increasing year by year. With the continuous improvement of people's living standards, more than half of adults in China are now overweight or obese, posing a serious threat to people's health and increasing the social and economic burden. It has become a pressing major public health issue that needs to be addressed urgently. The concept of obesity can be traced back to the Huangdi’s Internal Classic (Huang Di Nei Jing), which describes it as "the problems in fat and affluent people are caused by excessive taking of rich food", and suggests that ''frequent intake of rich and greasy foods can produce interior heat. Sweet flavor causes chest fullness. That is why its spleen-Qi flows upwards and changes into consumption-thirst disease. It can be treated by Eupatorii Herba which is used to remove stagnant Qi''. The stagnant qi is caused by the transformation failure of rich and greasy food and wine, so obesity is the disease of stagnant qi. Obesity is caused by indulging in rich and greasy food, wine, spicy and flavorful foods, raw and cold foods, and sweet and greasy foods, or overeating and leading a sedentary lifestyle, staying up late, or experiencing emotional imbalances such as excessive joy, anger, worry, pensiveness, and fear. It can also be caused by congenital abnormalities, leading to improper functioning of the spleen and stomach, dysregulation of the absorption and secretion of the small intestine, and the accumulation of stagnant Qi in the organs and muscles, resulting in a plump physique. The intake of food and drink depends on the functions of the stomach in receiving and decomposing, the small intestine in absorbing and secreting, and the spleen in transforming and transporting. The affected organs in obesity are the spleen, stomach, and small intestine. Orchids, specifically Eupatorii Herba and Lycopi Herba, are aromatic herbs that can regulate the smooth flow of Qi, eliminate stagnation, and cleanse impurities. In a broader sense, any aromatic and pungent substance that can invigorate the spleen, promote clarity, harmonize the stomach, reduce turbidity, and assist in the normal secretion and absorption functions of the small intestine, thereby eliminating excess, is referred to as orchid. Therefore, the treatment principle for obesity is to use ''orchids to eliminate stagnant Qi'', aiming to regulate the functions of the spleen, stomach, and small intestine using aromatic and pungent substances, gradually eliminating excessive dampness, phlegm, turbidity, and heat, and restore the balance of the middle energizer. This way, individuals who are obese can achieve a non-obese state.
RESUMEN
ObjectiveTo analyze and summarize the medication rules of different Pinelliae Rhizoma processed products in the syndrome differentiation and treatment of insomnia using data mining. MethodThe literature on the treatment of insomnia with Pinelliae Rhizoma was retrieved from the China National Knowledge Infrastructure (CNKI), VIP, and PubMed databases over the past 10 years. An Excel database was constructed to record the prescriptions of different Pinelliae Rhizoma processed products in the treatment of insomnia. SPSS 26.0 software was used for frequency analysis of traditional Chinese medicine (TCM) syndromes related to insomnia, compatibility of drugs, drug effects, and properties. SPSS 26.0 was also used for cluster analysis, factor analysis, and IBM Modeler 18.0 plugin for association rule analysis of the core compatibility of different Pinelliae Rhizoma processed products and combinations. ResultAfter applying inclusion and exclusion criteria, 125 relevant articles were finally included. The commonly used processed products of Pinelliae Rhizoma in the treatment of insomnia were Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, and Pinelliae Rhizoma Praeparatum cum Alumine. Among them, Pinelliae Rhizoma Praeparatum was the most frequently used. All three processed products of Pinelliae Rhizoma were often used for insomnia with such TCM syndromes as phlegm-heat disturbing the heart, phlegm-dampness obstructing the interior, and liver Qi stagnation. The compatible drugs were sweet, bitter, and pungent in flavor, cold in nature, and acted on the lung, spleen, heart, and liver meridians, with functions of nourishing deficiency, clearing heat, and calming the mind. The common prescriptions used were Wendantang, Chaihu Longgu Mulitang, Banxia Xiexintang, and Xiaochaihutang, with doses ranging from 6 to 30 g. The core drug combinations were Pinelliae Rhizoma Praeparatum-Poria-Ziziphi Spinosae Semen, Pinelliae Rhizoma Praeparatum Cum Zingibere et Alumine-Jujubae Fructus-Codonopsis Radix, and Pinelliae Rhizoma Praeparatum Cum Alumine-Scutellariae Radix-Bupleuri Radix. ConclusionThis study, for the first time, analyzed and summarized the compatibility and prescription application rules of commonly used processed products of Pinelliae Rhizoma in the treatment of insomnia from the perspective of TCM syndrome differentiation, which provides a theoretical basis for the rational, safe, and effective use of Pinelliae Rhizoma in the treatment of insomnia in TCM.
RESUMEN
Cardiovascular diseases are a class of circulatory system diseases involving the heart and vessels, including arrhythmia, hypertension, coronary heart disease, myocardial infarction, heart failure and so on. Due to the complicated pathogenesis, diverse disease types, and difficult treatment, cardiovascular diseases pose serious threatens to the human health. Therefore, it is urgent to develop effective therapies. Ferroptosis, a new type of cell death different from autophagy and apoptosis, is iron-dependent and accompanied by lipid peroxide accumulation. The mechanism of ferroptosis is complex. Recent studies have shown that iron homeostasis plays a role in the occurrence of ferroptosis, which may be induced by iron intake, utilization, and output and iron-related protein synthesis. In addition, iron homeostasis and ferroptosis have been confirmed to be involved in the pathological process of cardiovascular diseases, so regulating iron homeostasis and ferroptosis in cardiomyocytes may be a focus of the future research on cardiovascular diseases. Traditional Chinese medicine (TCM) provides a unique treatment method, and the unique syndrome differentiation system and treatment methods have been widely used in the clinical diagnosis, prevention, and treatment of cardiovascular diseases. Studies have demonstrated that TCM compound prescriptions and the active components in Chinese medicinal materials can regulate iron homeostasis and ferroptosis to protect cardiomyocytes. This paper introduces the mechanism of iron homeostasis in regulating ferroptosis and summarizes the effects of iron homeostasis-mediated ferroptosis on cardiovascular diseases. Furthermore, the research progress of TCM in regulating iron homeostasis-mediated ferroptosis in cardiovascular diseases is reviewed to provide new ideas for TCM prevention and treatment of cardiovascular diseases.

Children's fever is often accompanied by food accumulation. Traditional Chinese medicine believes that removing food stagnation while clearing heat of children can effectively avoid heat damage. To systematically evaluate the efficacy of Xiaoer Chiqiao Qingre Granules(XRCQ) in clearing heat and removing food accumulation and explore its potential mechanism, this study combined suckling SD rats fed with high-sugar and high-fat diet with injection of carrageenan to induce rat model of fever and food accumulation. This study provided references for the study on the pharmacodynamics and mechanism of XRCQ. The results showed that XRCQ effectively reduced the rectal temperature of suckling rats, improved the inflammatory environment such as the content of interleukin-1β(IL-1β), interleukin-2(IL-2), interferon-γ(IFN-γ), white blood cells, and monocytes. XRCQ also effectively repaired intestinal injury and enhanced intestinal propulsion function. According to the confirmation of its efficacy of clearing heat, the thermolytic mechanism of XRCQ was further explored by non-targeted and targeted metabolomics methods based on LTQ-Orbitrap MS/MS and UPLC-QQQ-MS/MS. Non-target metabolomics analysis of brain tissue samples was performed by QI software combined with SIMCA-P software, and 22 endogenous metabolites that could be significantly regulated were screened out. MetaboAnalyst pathway enrichment results showed that the intervention mechanism was mainly focused on tyrosine metabolism, tricarboxylic acid cycle, inositol phosphate metabolism, and other pathways. At the same time, the results of targeted metabolomics of brain tissue samples showed that XRCQ changed the vitality of digestive system, and inhibited abnormal energy metabolism and inflammatory response, playing a role in clearing heat and removing food stagnation from multiple levels.

RESUMEN
ObjectiveTo explore the characteristics of tongue manifestations and traditional Chinese medicine (TCM) syndromes in patients with primary Sjogren's syndrome (pSS) of different time. MethodpSS patients who visited TCM Department of Rheumatism in China-Japan Friendship Hospital from December 2018 to October 2021 were included and grouped according to the disease courses (short<5 years, medium 5-10 years, long > 10 years). Chi-square test was used for comparison between three groups and Bonferroni method for multiple comparisons. In the pairwise comparison, P<0.017 indicated significant difference. Chi-square test was performed on the syndrome and specific tongue manifestations with inter-group differences to analyze the trend of tongue manifestations and TCM syndromes over time (interval: two years). ResultA total of 193 pSS patients were enrolled, with 85 (44.0%) of short disease course, 69 (35.8%) of medium disease course, and 39 (20.2%) of long disease course. The common tongue manifestations were crimson tongue, fissured tongue, thin tongue, lack of fluid, and dry coating, which showed no significant difference among the three groups. Higher proportion of patients with light red tongue was observed in the group with short disease course than in group with medium disease course (χ2=6.407, P<0.017). Higher proportions of patients with thick coating (χ2=6.784, P<0.017) and phlegm-dampness syndrome (χ2=11.545, P<0.017) and lower proportion of patients with Qi deficiency syndrome (χ2=12.706, P<0.017) were found in the group with short disease course than in the group with long disease course. Patients with medium (χ2=6.358, P<0.017) and long (χ2=8.279, P<0.017) disease course tended to have exfoliated coating compared with those with short disease course, and the proportion of patients with exfoliated coating rose and the proportion of patients with thick greasy coating decreased over time (Ptrend<0.05). In addition, the proportion of patients with phlegm-dampness syndrome decreased and that with Qi deficiency syndrome increased over time (Ptrend<0.05). ConclusionIn the early stage, patients with pSS often show both dryness and dampness, as manifested by the thick greasy coating and phlegm-dampness syndrome. In the medium and late stage, patients often have Qi-Yin deficiency, as evidenced by exfoliated coating and Qi deficiency. In the clinical practice, medicines should be prescribed based on tongue manifestations and TCM syndrome of patients.
RESUMEN
ObjectiveTo summarize the characteristics of traditional Chinese medicine (TCM) syndrome in primary Sjögren's syndrome (pSS) patients with interstitial lung disease (ILD) and to explore associated factors. MethodA survey was conducted and pSS patients who were treated in TCM department of rheumatism at China-Japan Friendship Hospital from December 2018 to April 2022 were included. Tongue manifestations and syndromes of patients were recorded. pSS patients with ILD were classified into the pSS-ILD group and those without the ILD were included in the pSS-non-ILD group. The tongue manifestations, syndromes, and laboratory indexes were compared between the two groups, and logistic regression was used to explore the factors associated with pSS-ILD. ResultA total of 200 pSS patients were included, with 186 (93.0%) females, median age of 57 years, and median disease course of 60 months, of which 44 (22%) had pSS-ILD. In terms of tongue manifestations, pSS-ILD patients generally had dark/purple/stasis tongue, fissured tongue, and tongue with little fluid, thick coating, yellow coating, and greasy coating. The proportion patients with yellow coating was higher in pSS-ILD group than in the pSS-non-ILD group (χ2=4.799,P<0.05). In terms of syndrome, more than 40% of pSS-ILD patients had Qi deficiency, Yin deficiency, phlegm-dampness, Qi stagnation, and/or blood stasis syndrome. As for Yin deficiency, liver-kidney Yin deficiency syndrome ranked the first. For Qi deficiency, lung Qi deficiency syndrome was most commonly seen. The proportion of patients with lung Qi deficiency was higher in the pSS-ILD group than in the pSS-non-ILD group (χ2=18.667,P<0.01). As to laboratory indexes, compared with the pSS-non-ILD group, pSS-ILD group had high proportion of anti-SSA-positive patients (P<0.05) and high levels of C-reactive protein (CRP) (P<0.01), complement C3 (χ2=4.332,P<0.05), and complement C4 (P<0.05). Logistic regression analysis showed that pSS with ILD was positively associated with lung Qi deficiency [odds ratio (OR)=6.079, 95% confidence interval (CI) 2.585-14.298, P<0.01)] and yellow coating (OR=5.260, 95% CI 1.337-20.692, P<0.05) and negatively associated with low C4 (OR=0.199, 95% CI 0.070-0.564, P<0.01). ConclusionAbout 22% of pSS patients had ILD, and patients with pSS-ILD generally have Qi deficiency, Yin deficiency, phlegm-dampness, Qi stagnation, and/or blood stasis syndrome. Yellow coating, lung Qi deficiency and C4 level are factors associated with pSS combined with ILD.

Digestive tract diseases, especially digestive tract tumors, including liver cancer, pancreatic cancer, and colorectal cancer, have high incidence in China. Digestive tract tumor is one of the top 10 cancers in terms of the number of new cases and deaths in the world, and the incidence and mortality of tumor diseases have been increasing year by year. Therefore, the prevention and treatment of tumors is particularly important. With the application and promotion of traditional Chinese medicine in the medical field and the rapid development of molecular biology and pharmacology, more and more potential active components of Chinese medicinal materials have been extracted and studied. These active components can inhibit tumor cells in a multi-target and multi-pathway manner. Cinobufotalin is an effective component extracted from the skin of Bufo bufo gargarizans. It has been prepared into a variety of agents with anti-tumor, immunomodulatory, cardiac boosting, pain-easing, anti-inflammatory, and swelling-relieving activities. In clinical practice, cinobufotalin is mainly used to assist the treatment of liver cancer, lung cancer, colorectal cancer, gastric cancer and other malignant tumors, which can reduce the adverse reactions of patients in the middle and late stages and improve the quality of life and five-year survival rate of patients. The available studies of molecular mechanism have demonstrated that cinobufotalin can play a therapeutic role by inducing cell apoptosis, regulating cell cycle, inhibiting cell proliferation and angiogenesis, modulating immune response, reversing multidrug resistance, enhancing radiochemotherapy sensitivity, inhibiting tumor inflammation, invasion, and metastasis, etc. This review focuses on the clinical application and mechanism of cinobufotalin against digestive tract tumors in recent years, aiming to provide a theoretical basis for the anti-tumor research of cinobufotalin, promote the application of cinobufotalin in tumor treatment, and facilitate the further research and development of this compound.
RESUMEN
ObjectiveTo investigate the clinical effect of Guanxin Shutong capsules (GXSTC) on coronary heart failure with heart blood stasis. MethodA total of 98 coronary heart failure patients with heart blood stasis who visited the expert clinics of the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from June 2020 to August 2022 were selected. They were randomized into a control group and an observation group, with 49 in each group. The two groups were given standardized treatment according to the guidelines for coronary heart failure. On this basis, the observation group was treated with Chinese patent medicine GXSTC. The cardiac structural and functional indicators, total effective rate of symptoms, exercise tolerance, heart rate variability (HRV), quality of life and inflammatory factor levels of the two groups before and after treatment were compared. ResultBefore treatment, there was no notable difference in high-sensitivity C-reactive protein (hs-CRP), six minute walk test (6MWT), minnesota living with heart failure questionnaire (MLHFQ) score, left ventricular ejection fraction (LVEF), tumor necrosis factor-α (TNF-α), left ventricular end-diastolic diameter (LVEDD), N-terminal pro-brain natriuretic peptide (NT-proBNP) and HRV between the two groups, and thus the data were comparable. After treatment, the observation group had higher effective rates of traditional Chinese medicine (TCM) symptoms (Z=-2.362, P<0.05) and New York heart association class (NYHA) functional classes (Z=-2.175, P<0.05) than the control group. The two groups presented decreased LVEDD, TNF-α, NT-proBNP and hs-CRP (P<0.05, P<0.01) while increased MLHFQ, 6MWT and HRV(P<0.05,P<0.01) after treatment as compared with those before treatment, and the observation group had more decrease or increase than the control group (P<0.05, P<0.01). ConclusionGXSTC combined with standardized treatment relieves the physical symptoms of coronary heart failure patients with heart blood stasis, improves exercise tolerance and quality of life, reduces inflammatory reaction, increases HRV, and improves cardiac structure and function.
RESUMEN
BACKGROUND: Apoptosis is thought to be involved in all processes, including normal cell cycle, immune system, atrophy, embryonic development, and chemical-induced cellular damage. However, if the normal apoptotic process fails, the results might be disastrous, e.g., chondrocytes damage in tibial dyschondroplasia (TD). TD is a worldwide issue in the poultry sector due to thiram toxicity. Thiram (Tetramethyl thiuram disulfide) is a dithiocarbamate pesticide and fungicide commonly used in horticulture to treat grains meant for seed protection and preservation. PURPOSE: According to prior studies, chlorogenic acid (CGA) is becoming essential for regulating apoptosis. But still, the specific role of CGA in chondrocyte cells remains unclear. The present study explored the molecular mechanism of CGA on chondrocytes' apoptosis with B-cell lymphoma 2 signaling under the effect of miR-460a. METHODS: An in vivo and in vitro study was performed according to our previously developed methodology. Flow cytometry, western blotting, reverse transcription-quantitative polymerase chain reaction, and immunofluorescence assay were used to investigate the involvement of apoptosis and inflammasome related pathways. RESULTS: The CGA decreased the apoptosis rate with the deactivation of miR-460a, accompanied by the activation of Bcl-2. The high expression of miR-460a reduced the cell viability of chondrocytes in vitro and in vivo, that led to the interleukin-1ß production. While the apoptotic executioners (caspase-3 and caspase-7) acted upstream in miR-460a overexpressing cells, and its depletion downgraded these executioners. The CGA administrated cells negatively regulated miR-460a expression and thus indicating the deactivation of the apoptotic and inflammasome related pathways. CONCLUSION: Chlorogenic acid had a negative effect on miR-460a, setting off specific feedback to regulate apoptotic and inflammasome pathways, which might be a key feature for chondrocytes' survival.

BACKGROUND: Pelvic organ prolapse (POP) is seen in up to 30-70% of women presenting for routine gynecology care and 10% of women suffering from bothersome POP symptoms. Vaginal childbirth is one of the most prominent contributing factors for POP. Pelvic muscle training (PFMT) is considered effective to improve mild to moderate POP symptoms. In addition, higher-intensity, supervised PFMT aided by biofeedback and electrical stimulation may confer greater benefit. However, the long-term efficacy of the PFMT combined with electromyography biofeedback is unknown, which indicates the need for further evidence. METHODS: This multicenter randomized controlled trial compares the effectiveness and cost-effectiveness of conventional PFMT versus biofeedback-mediated PFMT plus neuromuscular electrical stimulation (NMES) for postpartum symptomatic POP women. The primary outcome is the proportion of patients with the improvement of at least one POP-Q stage at 36 months after randomization. The primary economic outcome measure is incremental cost per quality-adjusted life year at 36 months. Two hundred seventy-four women from four outpatient medical centers are randomized and followed up with pelvic floor examination, questionnaires, and pelvic ultrasonography imaging. All participants are arranged for three appointments over 12 weeks. NMES and electromyography biofeedback via intravaginal probe are added to PFMT for participants in the biofeedback-mediated PFMT group. Group allocation could not be blinded from participants and healthcare staff that deliver intervention but remain masked from medical staff that carry out PFM assessment. An intention-to-treat analysis of the primary outcome will estimate the difference of the proportion of POP-Q stage improvement between the trial groups right after the intervention, and during the follow-up until 36 months, using the chi-square test and multilevel mixed models respectively. A logistic regression analysis was used for adjusting for important baseline variables that are unbalanced. DISCUSSION: The trial results will provide evidence of the effectiveness of electromyography biofeedback-mediated PFMT in improving women's POP-Q staging, quality of life, and cost-effectiveness. TRIAL REGISTRATION: CCTR Registry ChiCTR210002171917 . Registered on March 6, 2019.

Background: This study set out to determine the prevalence and possible risk factors of headache and/or migraine in U.S. children, as well as the prevalence of complementary medicine use in this population. Methods: This is a secondary analysis of data from the 2017 U.S. National Health Interview Survey. Sociodemographic and clinical characteristics were compared between individuals with and without headaches. A backward stepwise procedure with a logistic regression statistic was used to test for potential predictors. Results: Six percent of children reported headaches and/or migraine within the past 12 months. Headaches were predicted by older age, female sex, non-Hispanic white ethnicity, and living in the southern United States. Inability to afford balanced meals and feeling sad or depressed in the past 6 months were also associated with higher odds of headache. A total of 19.2% of children with headaches reported using mind-body medicine, compared with 12.2% of children without headaches. Most frequently used therapy was yoga (57.2%), followed by spiritual meditation (31.1%) and mindfulness meditation (24.0%). The prevalence of visits to a complementary medicine practitioner or healer was 12.5%. Most frequently seen practitioners were chiropractors (62.1%), followed by naturopaths (21.2%), homeopaths (14.1%), and traditional healers (2.5%). Conclusions: The common use of complementary medicine among children suffering from headaches is worth noting. Understanding the motivation for using complementary medicine, as well as the choice of different forms of such therapy, may shed further light on the health-seeking behavior of this population.

Some kinds of chronic sialadenitis were recognized during the recent years. They have specific pathogenesis, clinical and histopathologic appearances, and require specific treatment. IgG4-related sialadenitis (IgG4-RS) is one of the immune-mediated diseases, characterized by tumefactive lesions. The incidence of IgG4-RS obviously increased during the past 30 years. The study on the potential relationship between occupational exposure to chemical substances and the incidence of IgG4-RS showed that subjects with occupational exposure to agents known to cause IgG4-RD had an increased risk for IgG4-RS. Surgical excision of involved SMG could not control the disease progression, which is not recommended for treatment of IgG4-RS. The combination of glucocorticoid and steroid-sparing agents is effective for treating IgG4-RS, and restores salivary gland function. Radioiodine induced sialadenitis (RAIS) is one of the common complications of postoperative adjuvant treatment of differentiated thyroid cancer by 131I. The incidence of the disease is related to radiation dosage. Clinically, the patients suffered from swelling and tenderness in the buccal or submandibular regions, especially during the mealtime. Imaging appearances are similar to those of chronic obstructive sialadenitis. Conservative managements, such as gland massage, sialagogues, are the mainstream methods in the treatment of RAIS. Sialendoscopy is feasible for RAIS, but not as effective as conventional obstructive sialadenitis (COS). Therefore the prevention of RAIS is crucial. Eosinophilic sialodochitis (ES) is a new type of chronic inflammatory disease of the salivary gland related to allergy. It has characteristics of swelling of multiple major salivary glands, strip-like gelatinous plugs discharged from the duct orifice of the gland, elevated level of serum IgE and eosinophils in peripheral blood, infiltration of eosinophils and IgE positive plasma cells in the tissues, allergic history, increased expression of allergy-related cytokines, such as IL-4, IL-5, IL-13, and eotaxin, which suggest allergic reactions as a potential pathogenesis of the disease. The clinical, laboratory, histological, and immunohistochemical characteristics of ES are significantly different from conventional obstructive sialadenitis (COS). Therefore, it is suitable to separate ES from COS. Conservative managements, such as self-maintenance therapy and anti- allergic modality are the choices of treatment for ES. Based on the results of our comprehensive studies a new classification of chronic sialadenitis is suggested.
