RESUMO

Background: Endometriosis (EMs) is a common chronic inflammatory disease which is characterized by multiple clinical symptoms and high recurrence rate due to the absence of effective therapies. Huayu Jiedu Formula (HYJDF), is a traditional Chinese medicine prescription with five major herbs. It has been used as traditional medicine to treat EMs for more than twenty years and exerted a good therapeutic effect. However, the underlying mechanism is unclear. Here we aim to observe the effects of HYJDF on EMs and investigate the therapeutic mechanism. Methods: The extract components of HYJDF were identified and quantified by an UHPLC-QE-MS method. Network pharmacology was used to obtain the core targets of HYJDF for the treatment of EMs and the specific biologic processes involved. A total of 68 EMs cases were randomly divided into control (gestrinone) and observation (HYJDF) groups. The overall effectiveness, pain scores, cyst-size changes, serum CA125 levels, quality-of-life scores, safety, and adverse events were evaluated before and after treatment. For the mechanism research, DNA methylation-chip analysis was performed to determine the differential genes. EMs mice models and human ectopic stromal cells (ESCs) were treated with HYJDF and its pharmaceutical serum, respectively. The ectopic foci was measured via H&E staining while the expressions of the target genes were verified by real-time PCR and Western blot analysis. The inflammatory cytokine levels in the peritoneal fluid of mice were detected by ELISA. The proliferative potential of cells was analyzed by MTS whereas the apoptosis and cell cycle were determined through flow analysis. Results: The total number of components detected in positive and negative ion modes was 839 and 597, respectively. Network pharmacology suggested that HYJDF treated EMs through DNA methylation. We found that HYJDF and gestrinone exerted good therapeutic effect with no obvious difference, but the HYJDF treatment group had fewer side effects. GATA 6, which was hypomethylated and abundant in endometriotic cells, potently induced inflammatory response. This finding indicated the important role of GATA 6 in EMs development. Moreover, HYJDF ameliorated inflammatory response (i.e., reduced the levels of IL-1ß and PGE2 in peritoneal fluid), suppressed ESCs proliferation, and increased cell apoptosis by down-regulating GATA 6 expression. Conclusion: We demonstrated that HYJDF has anti-inflammation activity and increased cell apoptosis through the reduction of GATA 6 expression in ectopic tissues, which showed good therapeutic effect without any obvious side effects. These findings suggest that HYJDF may be a new and efficient traditional Chinese medicine for the treatment of EMs.

RESUMO

OBJECTIVE: Tracheostomy is performed for various indications ranging from prolonged ventilation to airway obstruction. Many factors may play a role in the incidence of complications in the immediate post-operative period including patient-related factors. Chronic obstructive pulmonary disease and asthma are some of the most common pulmonary pathologies in the United States. The relationship between obstructive pulmonary diseases and acute post-tracheostomy complications has been incompletely studied. DESIGN: A retrospective chart review was designed in order to answer these objectives. Medical records were reviewed for the technique used, complications, and contributing patient factors. Post-operative complications were defined as any tracheostomy-related adverse event occurring within 14 days. SETTING: The study took place at an academic comprehensive cancer. PARTICIPANTS: Inclusion criteria included patients from January 2017 through December 2018 who underwent a tracheostomy. Exclusion criteria included presence of stomaplasty, total laryngectomy, and tracheostomies performed at outside hospitals. MAIN OUTCOME MEASURES: Patient factors examined included demographics, comorbidities, and body mass index with the primary outcome measured being the rate of tracheostomy complications. RESULTS: The most common indication for tracheostomy among the 321 patients that met inclusion criteria was airway obstruction or a head and neck cancer surgical procedure. Obstructive sleep apnea was associated with acute complications in bivariate analysis (29.4% complications, p = .003). Chronic obstructive pulmonary disease and asthma were not associated with acute complications in bivariate analysis (11.6% complications, p = .302). Among the secondary outcomes measured, radiation was associated with early complications occurring in post-operative days 0-6 (1.1%, p = .029). CONCLUSION: Patients with obstructive sleep apnea may have a higher risk of acute post-tracheostomy complications that might be due to the patient population at risk for obstructive sleep apnea. Patients with obstructive pulmonary pathologies such as asthma or chronic obstructive pulmonary disorder did not have an elevated risk of complications which is clinically significant when considering the utility of ventilation and tracheostomy in the management of acute respiratory failure secondary to these conditions.

RESUMO

Currently, osteoarthritis (OA) is thought to be the most prevalent chronic joint disease worldwide. The epidemiology of this disorder is complex, and the treatment is challenging. Xian-Ling-Gu-Bao (XLGB) capsule, a herbal compound preparation, is widely used for the treatment of bone disorders, including OA. Although its efficacy and safety have been demonstrated in clinical trials and practice, the underlying medicinal constituents and mechanism have not been clearly elucidated. Therefore, this study aimed to explore the medicinal constituents and mechanism of XLGB for OA treatment. The phytochemical constituents in XLGB capsule were detected by liquid chromatography-mass spectrometry (LC-MS), the medicinal constituents and therapeutic mechanism for OA treatment were deduced by network analysis, and the deduced mechanism was validated by in vitro experiment. As a result, a total of 55 constituents were detected in XLGB extract, in which 16 constituents were screened out for target collection. Based on the analysis of target profile, XLGB targets showed a high degree of similarity with OA targets. Network analysis revealed that XLGB had a holistic effect of multiple active constituents on multiple targets and pathways. The core targets of XLGB were presumed to be MAPKs, PI3K, AKT, BCL2, RELA, TNF, NOS2, and so on, and the mechanism was speculated to mainly inhibit chondrocyte apoptosis and inflammatory response through JNK and PI3K/AKT/NF-κB signaling cascades. Finally, in vitro study confirmed that XLGB extract protected ATDC5 cells against lipopolysaccharide- (LPS-) induced apoptosis and inflammatory response, and these effects were supposed to be involved in the inhibition of JNK and PI3K/AKT/NF-κB pathways. Our study could provide a scientific basis for further research and clinical use of XLGB capsule.

RESUMO

Endometriosis (EM) is a common chronic inflammatory disease in women. Sampson's retrograde menstruation theory is the most widely accepted theory of EM pathogenesis. The periodic bleeding of ectopic lesions is an important pathological feature of this disease, and the occurrence and progression of EM are closely associated with the iron overload caused by ectopic lesions. However, animal models that simulate menstrual-blood reflux and hemorrhage from EM lesions are lacking. In this study, we performed intraperitoneal injection of endometrial fragments and periodic intraperitoneal blood injection to simulate the real cause and disease state of EM and successfully constructed a mouse model of EM iron overload. Our research found that the number, size, and degree of adhesion of EM lesions in the iron-overload model mouse were significantly higher than those in the model mouse. Moreover, the iron concentration in the abdominal fluid and ovary significantly increased, and the level of malondialdehyde (MDA) in the ovary increased. Conversely, GPX4, GSH, and other anti-ferroptosis-related proteins were downregulated, proving the occurrence of ferroptosis. Huayu Jiedu Fang (HYJDF) is an empirical prescription for EM treatment. This study combined animal experiments, UHPLC-QE-MS analysis, and network pharmacology to analyze whether HYJDF can inhibit ferroptosis to slow down the progression of EM and protect ovarian function. Based on the constructed iron-overload model, HYJDF can reduce the volume of EM lesions and the degree of adhesion, downregulate the total iron concentration in the peritoneal fluid and ovary, upregulate GPX4 expression and GSSG in the ovary, downregulate the level of MDA in the ovary, and promote the development of follicles. We further confirmed that HYJDF can inhibit the progression of EM disease and improve the ovarian function of the model mouse by inhibiting ferroptosis. Finally, through UHPLC-QE-MS and network pharmacology analysis, the natural compounds in HYJDF were identified and verified and the regulatory effect of HYJDF on the EM ferroptosis pathway through the IL-6/hepcidin pathway was preliminarily elucidated.

RESUMO

RATIONALE: Bear bile powder (BBP) is a widely used traditional Chinese medicine (TCM), and bile acids (BAs) are the main active components in BBP. Due to the scarcity of BBP resources, adulterations often occur in the market. Conventional methods to distinguish them are usually complicated and time-consuming. To enhance effectiveness and accuracy, a rapid and rough analytical method is desperately needed. METHODS: In this study, a rapid strategy using chip-based nano-electrospray ionization tandem mass spectrometry (nano-ESI-MS/MS) was established to distinguish BBP from other sources of bile powder (BP). In addition, the results were further verified by ultra-high-performance liquid chromatography combined with high-resolution mass spectrometry (UPLC/MS). RESULTS: The precision of the chip-based nano-ESI-MS/MS method was validated to be acceptable with relative standard deviation (RSD) <15%. The distinction between BBP and other sources of BP, including common adulterants of pig bile powder (PBP), cattle bile powder (CBP), sheep bile powder (SBP), and chicken bile powder (CkBP), can be observed in the spectra. By using orthogonal partial least-squares discriminant analysis (OPLS-DA), more potential m/z markers were investigated. A BAs-related m/z marker of 498.3 was discovered as a typical differential molecular ion peak and was identified as tauroursodeoxycholic acid (TUDCA) and taurochenodeoxycholic acid (TCDCA) in BBP. CONCLUSIONS: The proposed strategy has simple sample pretreatment steps and significantly shortened analysis time. As an emerging technology, chip-based nano-ESI-MS not only provides a reference for the rapid distinction of adulterated Chinese medicines, but also provides some insights into the identification of other chemicals and foods.

RESUMO

PROBLEM: This study aims to investigate the effects of alpha-linolenic acid (ALA) on the gut microbiota (GM) and the abdominal environment in mice with endometriosis (EMS). METHODS: The effects of faecal microbiota transplantation (FMT) from EMS mice on mice treated with antibiotic cocktail were conducted. The 16S rRNA sequencing and PICRUSt software were used to detect the structure and function of GM respectively. The protein levels of Claudin 4 and ZO-2 in the intestinal wall were detected using the western blotting. The level of LPS in the abdominal cavity was detected using enzyme-linked immunosorbent assay (ELISA). The content of macrophages in the abdominal cavity was detected using flow cytometry. RESULTS: The exogenous supplementation of ALA could restore the abundance of Firmicutes and Bacteroidota in EMS mice. After the ALA treatment, the abundance of 125 functional pathways and 50 abnormal enzymes related to GM in EMS mice was significantly improved (p < .05). The expression of the ZO-2 protein in the intestinal wall was decreased, and the level of LPS in the abdominal cavity was significantly increased after FMT from EMS mice (p < .05). ALA could increase the expression of the ZO-2 protein in the intestinal wall of EMS mice, reduce the level of LPS in the abdominal cavity (p < .05) and reduce the aggregation of peritoneal macrophages (p < .05). CONCLUSION: Alpha-linolenic acid can improve the GM, intestinal wall barrier and abdominal inflammatory environment and reduce the level of LPS in mice with EMS.

RESUMO

Mouse trophoblast stem cells (TSCs) can differentiate into trophoblast cells, which constitute the placenta. Under conventional culture conditions, in a medium supplemented with 20% fetal bovine serum (FBS), fibroblast growth factor 4 (FGF4), and heparin and in the presence of mouse embryonic fibroblast cells (MEFs) as feeder cells, TSCs maintain their undifferentiated, proliferative status. MEFs can be replaced by a 70% MEF-conditioned medium (MEF-CM) or by TGF-ß/activin A. To find out if KnockOutTM Serum Replacement (KSR) can replace FBS for TSC maintenance, we cultured mouse TSCs in KSR-based, FBS-free medium and investigated their proliferation capacity, stemness, and differentiation potential. The results indicated that fibronectin, vitronectin, or laminin coating was necessary for adhesion of TSCs under KSR-based conditions but not for their survival or proliferation. While the presence of FGF4, heparin, and activin A was not sufficient to support the proliferation of TSCs, the addition of a pan-retinoic acid receptor inverse agonist and a ROCK-inhibitor yielded a proliferation rate comparable to that obtained under the conventional FBS-based conditions. TSCs cultured under the KSR-based conditions had a gene expression and DNA methylation profile characteristic of TSCs and exhibited a differentiation potential. Moreover, under KSR-based conditions, we could obtain a suspension culture of TSCs using extracellular matrix (ECM) coating-free dishes. Thus, we have established here, KSR-based culture conditions for the maintenance of TSCs, which should be useful for future studies.

RESUMO

Plantaginis semen, the dried mature seed of Plantago asiatica L. or Plantago deprdssa Willd., has a prominent effect on the treatment of obesity, type 2 diabetes and lipid disorders, however, its clinical application is limited due to inadequate in-depth mechanism exploration and incomplete discussion of action targets of its in vivo. Therefore, an untargeted metabolomics approach was firstly applied to study the serum metabolic differences in mice. Metabolomics analysis was performed using ultra performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-QTOF-MS) together with multivariate statistical data analysis. The results showed that Plantaginis semen can mainly improve blood lipids, some degree in blood glucose and insulin levels in high-fat mice, in addition, the phenotype of liver and fat stained sections demonstrated remarkable results. A total of 22 metabolites involved in arachidonic acid, glycerophospholipid, glycosphingolipid, linoleate, Omega-3 fatty acid, phosphatidylinositol phosphate and tyrosine metabolisms were identified. In further, it was found that the possible mechanisms of Plantaginis semen on hyperlipidemic mice lied in the biosynthesis of thyroxine, biological effects of enzymes of phospholipase A2 activity, glucosylceramide synthase and inositol essential enzyme 1α, genes expressions of fatty acid metabolism and inflammation. Serum metabolomics revealed that Plantaginis semen could cure the organism disease via regulating multiple metabolic pathways which will be helpful for understanding the mechanism of this herb and providing references for better applications of it in clinic, even researches on other TCMs.

RESUMO

In this paper, a novel high throughput screening method for antioxidants was described. The screening process was completed on a 5 cm × 5 cm silica gel 60 plate. Luminol was used as the fluorogenic substrate while hydrogen peroxide employed to excite the chemiluminescence. A dark spot was observed due to quenching effect of antioxidant. A linear model of the integral area of the spot as a function of analyte amount was fit by using vitamin C as positive control. Excellent linearity (R2 = 0.9978) was obtained in the range of 2.31-23.1 µg. The variation coefficients of intra- and inter-chip precisions were below 5% (n = 10) and 10% (n = 6) respectively. The new method was validated by comparing the analysis result of six flavonoids with that from a sequential injection method. The Pearson correlation coefficient was up to 0.98. A set of traditionally used herbal medicines was screened, and Rhei Radix et Rhizoma showed the strongest signal. The major bioactive ingredients were further assigned by flow injection and MS analyses. These results reveal the prospects of the proposed method to supply a promising tool in vitro for high throughput screening and activity evaluation of antioxidants in a fast, low-cost and reliable manner.

RESUMO

A randomized, double-blind, active parallel controlled trial will be conducted to include patients with acute upper respiratory infection and wind-warmth lung heat disease (heat in lung-wei pattern). Patients with serious bacterial infection (white blood cell count>1.2×1010, neutrophil>80%) will be excluded.so as to further identify Jinye Baidu Granule indications of Wind-warmth lung heat disease (heat in lung-wei pattern).According to the subjects of symptoms of fever and sore throats,Patients will be divided into three blocks: fever, swelling and sore throat, combined fever and swelling and sore throat. Subjects in three blocks will be divided into treatment group and control group with stratified blocked randomization. The treatment group will be treated with Jinye Baidu Granule, and the control group will be treated with Fufang Shuanghua granule. Primary outcome measure of patients with fever will be body temperature recovery time. Primary outcome measure of patients with swelling and sore throat will be throat symptom score. Primary outcome measures of patients combined with fever and swelling and sore throat will be body temperature recovery time and throat symptom score. Before and after all of the patients in the group were collected blood and urine routine, liver and renal function, electrocardiogram (ECG) data as the safety index while observing it adverse events. A total of 623 patients were included. Compared with control group,sore throat symptoms of patients with sore throat and pharyngeal symptoms total score have significantly different. so Jinny Baidu granule have a significant advantage in the treatment of sore throat. All of the experiments showed that the safety of the drug was good. Nausea, vomiting, stomach pain, diarrhea, digestive tract symptoms may occur only occasionally. We should pay attention to the changes when using in patients with spleen deficiency cold to avoid adverse reaction.

RESUMO

OBJECTIVES: To test whether text message reminders sent to caregivers improve the effectiveness of a home micronutrient fortification program in western China. METHODS: We carried out a cluster-randomized controlled trial in 351 villages (clusters) in Shaanxi Province in 2013 and 2014, enrolling children aged 6 to 12 months. We randomly assigned each village to 1 of 3 groups: free delivery group, text messaging group, or control group. We collected information on compliance with treatments and hemoglobin concentrations from all children at baseline and 6-month follow-up. We estimated the intent-to-treat effects on compliance and child anemia using a logistic regression model. RESULTS: There were 1393 eligible children. We found that assignment to the text messaging group led to an increase in full compliance (marginal effect = 0.10; 95% confidence interval [CI] = 0.03, 0.16) compared with the free delivery group and decrease in the rate of anemia at end line relative to the control group (marginal effect = -0.07; 95% CI = -0.12, -0.01), but not relative to the free delivery group (marginal effect = -0.03; 95% CI = -0.09, 0.03). CONCLUSIONS: Text messages improved compliance of caregivers to a home fortification program and children's nutrition.

RESUMO

A quantitative method for epimedin A, B, C and icariin in rat plasma was established using LC-MS/MS after intermuscular administration of Chuankezhi injection to rat. Chromatographic separation was performed on an Agilent Eclipse XDB-C(18) column (150 mm × 2.1 mm, 5.0 µm) at 40 ℃. Mobile phase consisted of acetonitrile-0.1% formic acid in water(35∶65), and the flow rate was 0.22 m L·min(-1). The LC effluent was detected and analyzed using an ESI-triple quadrupole tandem mass spectrometer under the multiple reaction monitoring (MRM) in the negative ion mode. The plasma samples were treated with solid phase extraction prior to LC-MS/MS analysis. As a result, all of the four analytes displayed a good linearity over the concentration of 1-1 000 ng·mL(-1). The RSDs of intra-day and inter-day assays were less than 5.99% and 10.16%, respectively. The relative recovery of each analyte was between 88.1%-101.1% with RSD < 7.9% and the absolute recovery was between 72.0%-86.6%(RSD < 6.3%). In conclusion, the established method shows good specificity, sensitivity and efficiency for quantifying the four flavonoid glycosides contained in rat plasma.

RESUMO

To study pharmacokinetic characteristics of epimedin A, B, C and icariin after intermuscular administration of Chuankezhi injection to rat. The established RRLC-MS/MS method was applied for simultaneous determination of four analytes in rat plasma and calculating their pharmacokinetic parameters. As a result, each analyte showed a good linear relationship in the concentration range of 1-1 000 µg•L⁻¹.The intra-day precise was 96.9%-107.5% with RSD<5.99%, inter-day precise was 92.3%-105.0% with RSD<10.16%. The relative recovery of four analytes was 88.1%-101.1% with RSD<7.9% and their absolute recovery was 72.0%-86.6% with RSD<6.3%. After intermuscular administration of Chuankezhi injection, the plasma concentration of four flavonoid glycosides rapidly arose to peaks at about 10 min, and then quickly declined in rat. Tmax of epimedin A, B, C and icariin was 0.21, 0.19, 0.16 and 0.49 h, respectively, and their mean elimination half-life(t1/2z) was 0.60, 0.62, 0.47 and 0.49 h. The established method was validated to be sensitive, rapid and specific for determination of the four analytes. Serum concentration of 4 species of epimedium flavonoids in Chuankezhi injection was low, and their absorption and elimination seem quickly, displaying similar pharmacokinetic characteristics in this study.

RESUMO

OBJECTIVE: To evaluate the effects of wrist-ankle acupuncture combined with ginger moxibustion against gastrointestinal tract reactions (nausea, vomiting, and constipation) to chemotherapy in cancer patients. METHODS: A total of 60 patients with gynecological tumors treated by chemotherapy were randomly divided into two groups. The treatment group (30 cases) underwent wrist-ankle acupuncture and ginger moxibustion, whereas tropisetron hydrochloride and dexamethasone were intravenously administered to the control group (30 cases) during chemotherapy. RESULTS: The frequency of nausea in the treatment group was significantly less than that of the control group from the 2nd to the 5th day of chemotherapy (P<0.01). The anti-emetic effect in the treatment group was significantly better than that in the control group on the 3rd day of therapy (P<0.05). The incidence rate of constipation was significantly lower in the treatment group than that in the control group (P<0.01). Furthermore, the cost of therapy for the treatment group was significantly lower than that of the control group (P<0.01). Only 1 patient manifested a post-acupuncture side effect in the form of subcutaneous blood stasis. CONCLUSION: Wrist-ankle acupuncture combined with ginger moxibustion could prevent gastrointestinal tract reactions to chemotherapy in cancer patients. In addition, the proposed method had fewer side effects, lower cost, and less risk.
