RESUMEN
BACKGROUND: Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder that frequently exhibits low-grade inflammation, pro-oxidant activity, and gut dysbiosis. PCOS has become one of the leading causes of female infertility worldwide. Recently, omega-3 polyunsaturated fatty acids (PUFAs) have been proven to benefit metabolic disorders in PCOS patients. However, its roles in the regulation of metabolic and endocrinal balances in PCOS pathophysiology are not clear. In the present study, we aimed to explore how omega-3 PUFAs alleviate ovarian dysfunction and insulin resistance in mice with dehydroepiandrosterone (DHEA)-induced PCOS by modulating the gut microbiota. METHODS: We induced PCOS in female mice by injecting them with DHEA and then treated them with omega-3 PUFAs. 16S ribosomal DNA (rDNA) amplicon sequencing, fecal microbiota transplantation (FMT) and antibiotic treatment were used to evaluate the role of microbiota in the regulation of ovarian functions and insulin resistance (IR) by omega-3 PUFAs. To further investigate the mechanism of gut microbiota on omega-3-mediated ovarian and metabolic protective effects, inflammatory and oxidative stress markers in ovaries and thermogenic markers in subcutaneous and brown adipose tissues were investigated. RESULTS: We found that oral supplementation with omega-3 PUFAs ameliorates the PCOS phenotype. 16S rDNA analysis revealed that omega-3 PUFA treatment increased the abundance of beneficial bacteria in the gut, thereby alleviating DHEA-induced gut dysbiosis. Antibiotic treatment and FMT experiments further demonstrated that the mechanisms underlying omega-3 benefits likely involve direct effects on the ovary to inhibit inflammatory cytokines such as IL-1ß, TNF-α and IL-18. In addition, the gut microbiota played a key role in the improvement of adipose tissue morphology and function by decreasing multilocular cells and thermogenic markers such as Ucp1, Pgc1a, Cited and Cox8b within the subcutaneous adipose tissues. CONCLUSION: These findings indicate that omega-3 PUFAs ameliorate androgen-induced gut microbiota dysbiosis. The gut microbiota plays a key role in the regulation of omega-3-mediated IR protective effects in polycystic ovary syndrome mice. Moreover, omega-3 PUFA-regulated improvements in the ovarian dysfunction associated with PCOS likely involve direct effects on the ovary to inhibit inflammation. Our findings suggest that omega-3 supplementation may be a promising therapeutic approach for the treatment of PCOS by modulating gut microbiota and alleviating ovarian dysfunction and insulin resistance.

OBJECTIVE@#To observe the effect of acupuncture at "Feishu" (BL 13) + "Dingchuan" (EX-B 1) and "Kongzui" (LU 6) + "Yuji" (LU 10) for the airway remodeling in asthma rats based on the transforming growth factor-β1 (TGF-β1)/ Smad family member 3 (Smad3) signaling pathway; and explore the efficacy difference between the two acupoint combinations.@*METHODS@#Forty SPF male SD rats, aged 4 weeks, were randomly divided into a blank group (n = 10) and a modeling group (n = 30). The ovalbumin (OVA) sensitization method was used to establish asthma model in the modeling group. After successful model preparation, the rats of the modeling group were randomized into a model group, an acupuncture at "Feishu" (BL 13) + "Dingchuan" (EX-B 1) (AAF) group, and acupuncture at "Kongzui" (LU 6)+"Yuji" (LU 10) (AAK) group, with 10 rats in each one. Starting from day 15 of the experiment, 5 min after motivating, acupuncture was applied to "Feishu" (BL 13) + "Dingchuan" (EX-B 1) and "Kongzui" (LU 6)+"Yuji" (LU 10) in the AAF group and the AAK group respectively. The intervention was delivered for 30 min each time, once daily, lasting 3 weeks consecutively. Using lung function detector, the airway resistance (RL) and dynamic compliance (Cdyn) of the lungs were detected. The histomorphology of lung tissues was detected with HE staining and Masson staining, and the mRNA and protein expression of TGF-β1 and Smad3 in lung tissues was detected with the real-time PCR and Western blot methods.@*RESULTS@#Compared with the blank group, RL was increased and Cdyn was decreased in the rats of the model group (P<0.01); and RL was reduced and Cdyn was increased in the AAF group and the AAK group when compared with those in the model group (P<0.01, P<0.05). The rats of the model group had bronchial lumen stenosis, inflammatory cell infiltration, collagen fibre hyperplasia and thickened smooth muscle in the lung tissues when compared with those in the blank group; and in comparison with the model group, all of the above morphological changes were attenuated in the AAF group and the AAK group. Besides, these morphological changes of the lung tissues were more alleviated in the AAF group when compared with those in the AAK group. In comparison with the blank group, the mRNA and protein expression of TGF-β1 and Smad3 of the lung tissues was increased in the model group (P<0.01), and it was reduced in the AAF group and the AAK group when compared with that in the model group (P<0.05, P<0.01). The mRNA expression of TGF-β1 and Smad3 was lower in the AAF group when compared with that in the AAK group (P<0.05).@*CONCLUSION@#Acupuncture at either "Feishu" (BL 13)+"Dingchuan" (EX-B 1) or "Kongzui" (LU 6)+"Yuji" (LU 10) reduces the airway remodeling in the rats with asthma, which may be related to the down-regulation of mRNA and protein expression of TGF-β1 and Smad3. The better efficacy is obtained with acupuncture at "Feishu" (BL 13)+"Dingchuan" (EX-B 1).

ObjectiveTo observe the effect of Dahuang Xiezhuo prescription on the clinical symptoms, blood uric acid, and renal tubular function of patients with immunoglobulin A (IgA) nephropathy in stages 1-2 of chronic kidney disease (CKD) complicated with hyperuricemia (HUA). MethodSixty patients with IgA nephropathy in stages 1-2 of CKD complicated with HUA of spleen and kidney deficiency and combined turbidity and blood stasis syndromes were randomly divided into an observation group and a control group, with 30 cases in each group. The patients in the control group received basic treatment, i.e., losartan potassium tablets 50-100 mg/time, once per day, and sodium bicarbonate tablets 0.5 g/time, three times per day by oral administration, combined with low-salt, low-fat, and low-purine diet. The patients in the observation group received Dahuang Xiezhuo prescription on the basis of basic treatment, one dose per day, twice a day in the morning and evening with warm water. Both groups were treated for two months. The total scores of traditional Chinese medicine(TCM)syndrome, blood pressure, 24 h urinary protein (24 h UTP), blood urea nitrogen (BUN), serum creatinine (SCr) [glomerular filtration rate (eGFR) was calculated by CKD-epidemiology collaboration (CKD-EPI) formula], serum uric acid (SUA), and renal tubular function indexes [urinary α1-microglobulin (α1-MG), urinary β2-microglobulin (β2-MG), urinary kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL)] of the two groups before treatment and two months after treatment were recorded. The clinical efficacy of the two groups was evaluated two months after treatment. ResultAfter 2 months of treatment,the total effective rate in the observation group was 81.48%(22/27),higher than 50.00%(14/28) in the control group(χ2 =6.661,P<0.05). The total scores of TCM syndrome, 24 h UTP, and SUA in the observation group and the observation group were lower than those before treatment (P<0.05), and compared with the control group after treatment, the observation group decreased more significantly (P<0.05). After treatment, the blood pressure in the observation group and the observation group was lower than that before treatment (P<0.05), and there was no significant difference in blood pressure between the two groups after treatment. After treatment, the levels of urinary α1-MG, β2-MG, KIM-1, and NGAL in the two groups were lower than those before treatment (P<0.05), and the observation group was lower than the control group after treatment (P<0.05). There were no significant inter-group and intra-group differences in BUN, SCr, and eGFR levels before and after treatment. There were no obvious abnormalities in blood routine, liver function, and electrolytes before and after treatment in the two groups, and no adverse reactions such as allergies occurred. ConclusionDahuang Xiezhuo prescription can effectively improve the clinical symptoms of IgA nephropathy with HUA (CKD1-2) patients with spleen and kidney deficiency and combined turbidity and blood stasis syndromes, reduce blood uric acid level, alleviate renal tubular injury, and protect the kidney. The curative effect is better than that of basic treatment.
RESUMEN
ObjectiveTo observe the effectiveness and safety of Qihuang Yishen Granules (芪黄益肾颗粒) combined with traditional Chinese medicine (TCM) chronic disease management on patients with diabetic kidney disease with deficiency qi and yin. MethodsTotally 140 patients diagnosed as diabetic kidney diseases with deficiency of both qi and yin were randomly divided into control group and trial group,with 70 cases in each group. Patients in the control group were treated with symptomatic treatment and routine chronic disease management. Patients in the trial group added Qihuang Yishen Granules and chronic disease management with TCM characteristics on the basis of symptomatic treatment. The course of treatment in both groups lasted for 6 months. The changes of laboratory indexes and chronic disease management level scores of the two groups of patients before treatment and after 3 and 6 months of treatment were compared, and their correlation were analyzed.The laboratory indexes of urinary protein and renal function related indicators such as 24-hour urinary protein quantification (24 hUTP), serum creatinine (Scr), blood urea nitrogen (BUN), and estimated glomerular filtration rate (eGFR), and control compliance rate, as well as blood glucose and lipid related indicators such as glycosylated hemoglobin (HbA1c), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and control compliance rate were observed. The chronic disease management level scores included exercise,cognitive symptom management practice,communication with doctors, self-efficacy of symptom management,self-efficacy of disease commonness management. ResultsFinally,67 cases in the control group and 68 cases in the trial group completed the study. Compared with the group before treatment, the trial group had lower 24 hUTP and Scr, higher exercise score, total self-management score and all self-efficacy scale scores, higher TG at 3 months of treatment; at 6 months of treatment, the trial group had lower 24 hUTP, higher eGFR, and higher self-management scores and self-efficacy scale scores of all chronic diseases (P<0.05), and the control group had higher self-management total score (P<0.05). After 6 months of treatment, the trial group had lower 24 hUTP, Scr, LDL-C, and TG, higher eGFR, higher compliance rate of 24 hUTP, eGFR, LDL-C, and TG, and higher scores for all chronic disease management indexes compared with the control group (P<0.05). In terms of the correlation between laboratory indicators and chronic disease management level scores:there was a statistically significant difference in the correlation between 24hUTP and exercise,symptom management self-efficacy,and self-efficacy of disease commonness management (P<0.05 or P<0.01),all of which were negatively correlated. There was a statistically significant difference in the correlation between Scr and symptom management self-efficacy and self-efficacy of disease commonness management (P<0.01),both of which were negatively correlated. There was a statistically significant difference in the correlation between eGFR and symptom management self-efficacy and self-efficacy of disease commonness management (P<0.01),both of which were positively correlated. ConclusionQihuang Yishen Granules combined with chronic disease management of TCM can improve the level of proteinuria,renal function and lipid metabolism in patients with diabetic kidney disease with deficiency of both qi and yin,thus delaying the progress of diabetic kidney disease and also improve the level of chronic disease management of patients.
RESUMEN
Objectives@#. We aimed to develop a new calculation model for calcium requirements in dialysis patients following parathyroidectomy. @*Methods@#. A total of 98 patients with secondary hyperparathyroidism receiving parathyroidectomy from January 2014 to January 2022 were enrolled in this study. Among these patients, 78 were randomly selected for construction of the calcium requirement calculation model, and the remaining 20 patients were selected for model validation. The calcium requirement model estimated the total calcium supplementation for 1 week after surgery using variables with significant relationships in the derivation group by stepwise multiple linear regression analysis. Bias, precision, and accuracy were measured in the validation group to determine the performance of the model. @*Results@#. The model was as follows: calcium requirement for 1 week after surgery=33.798–8.929×immediate postoperative calcium+0.190×C-reactive protein–0.125×age+0.002×preoperative intact parathyroid hormone+0.003×preoperative alkaline phosphatase (R2=0.8). The model was successfully validated. @*Conclusion@#. We generated a novel model to guide calcium supplementation. This model can assist in stabilizing the serum calcium levels of patients during the early postoperative period. Furthermore, it contributes to the individualized and precise treatment of hypocalcemia in patients following parathyroidectomy.
RESUMEN
Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.
RESUMEN
ObjectiveTo present the health status of traditional Chinese medicine (TCM) constitutions more intuitively and comprehensively based on improved radar chart. MethodsParticipants who completed a 26-week comprehensive intervention based on TCM constitution from February 2013 to January 2014 in Zhuhai branch of Guangdong Provincial Hospital of Chinese Medicine were included in the study. They were divided into groups according to gender and age, i.e. young, middle-aged, and elderly male and female groups. TCM constitution scale and health survey short form (SF-36) were used to evaluate the 9 basic TCM constitution types and quality of life at three time points, including pre-intervention (T1), at 13-week intervention (T2), and at 26-week intervention (T3). The improved radar charts were drawn to visually present the comprehensive evaluation results on the health status of 9 TCM constitutions, and graphic features (area S value, perimeter L value) were extracted to construct a comprehensive health index for TCM constitutions (H value). Spearman correlation analysis was used to analyze the correlation between H value and SF-36 total score. ResultsAmong the included 509 participants, there were 45 elderly male, 76 elderly female, 60 middle-aged male, 140 middle-aged female, 53 young male and 135 young female. The radar charts for comprehensive evaluation of TCM constitution health status showed that the total areas for all groups increased at T3 compared to T1, with the most significant increase in the young population. In the middle-aged population, the fan-shaped areas of certain constitutions decreased at T2 than T1. At T3, the radar chart shapes for females were more balanced than males in the same age group. By calculating the features of function graphs, it was found that the S, L, and H values for the elderly population were relatively higher than those for the middle-aged and young population with the same gender, and the young population increased by highest ratio. The values measured at T3 compared to T1 showed average increase of 26% for S value (11% for the middle-aged and 14% for the elderly), 22% for L value (10% for the middle-aged and the elderly each), and 22% for H value (10% for the middle-aged and 9% for the elderly). The female had lower S and L values, as well as higher H value than the male of the same age group measured at T3. The correlation coefficient between the H value of all participants and the total SF-36 score was 0.662 (P<0.01). ConclusionThe comprehensive evaluation model for the health status of TCM constitution based on the improved radar chart constructed in this study can present the health status of TCM constitutions and intervention effectiveness more comprehensively and intuitively. It is suggested to regulate the constitution in pursuit of the dynamic balance of the constitution health status, as well as consider the parts from the whole, and put focus on the balance of nine TCM constitutions.
RESUMEN
OBJECTIVE: To investigate the effects of acupotomy on inhibiting abnormal formation of subchondral bone in rabbits with knee osteoarthritis (KOA). METHODS: A total of 24 New Zealand rabbits were randomly divided into four groups of 6 rabbits each [control, model, electroacupuncture (EA) and acupotomy]. Eighteen KOA model rabbits were established using a modified Videman method. Rabbits in EA and acupotomy groups received the intervention for 3 weeks. Then, the cartilage and subchondral bone unit were obtained and the histomorphological changes were recorded. Osteo-protegerin (OPG) and receptor activator of nuclear factor-κB ligand (RANKL) in subchondral bone were evaluated by Western blotting, real-time polymerase chain reaction and immunohistochemistry. RESULTS: Compared with the model group, both the acupotomy and EA groups showed a significant decrease in the Lequesne index (both 0.01) and Mankin score ( 0.01, < 0.05). In addition, both EA and acupotomy groups had a higher expression of total articular cartilage (TAC) ( 0.05, < 0.01) and lower expression of articular calcified cartilage (ACC)/TAC ( 0.05, < 0.05) compared with the model group. The thickness of the subchondral bone plate in EA and acupotomy groups were decreased (both 0.01) compared to the model group. Moreover, trabecular bone volume (BV/TV), protein and relative expression of OPG and the ratio of OPG/RANKL in the subchondral bone of acupotomy group were decreased statistically significant, while these parameters were not significantly changed in the EA group compared with the model group. CONCLUSIONS: In the rabbit model of KOA, acupotomy inhibits aberrant formation of subchondral bone by suppressing OPG/RANKL ratio as a potential therapy for KOA.

To clarify the key quality attributes of substance benchmarks in Danggui Buxue Decoction(DBD), this study prepared 21 batches of DBD substance benchmarks, and established two methods for detecting their fingerprints, followed by the identification of peak attribution and similarity range as well as the determination of extract and transfer rate ranges and contents of index components ferulic acid, calycosin-7-O-β-D-glucoside, and astragaloside Ⅳ. The mass fractions and transfer rates of DBD substance benchmarks from different batches were calculated as follows: ferulic acid(index component in Angelicae Sinensis Radix): 0.037%-0.084% and 31.41%-98.88%; astragaloside Ⅳ(index component in Astragali Radix): 0.021%-0.059% and 32.18%-118.57%; calycosin-7-O-β-D-glucoside: 0.002%-0.023% and 11.51%-45.65%, with the extract rate being 18.4%-36.1%. The similarity of fingerprints among 21 batches of DBD substance benchmarks was all higher than 0.9. The quality control method for DBD substance benchmarks was preliminarily established based on the HPLC fingerprint analysis and index component determination, which has provided a basis for the subsequent development of DBD and the quality control of novel related preparations.

Chronic heart failure is a serious heart disease with dyspnea and limited activity tolerance as the main clinical manifestations. Activation of the inflammatory system can significantly stimulate cardiac fibrosis and remodeling and promote the progression of heart failure, playing a key role in the development of the disease. Studies have confirmed that inflammation is involved in the development of different types of heart failure. "Toxic pathogen theory" is an important basic theory of traditional Chinese medicine (TCM) to explain the occurrence of diseases. We concluded the similarities between TCM toxic pathogens and inflammation in concept, disease location, etiology, syndrome differentiation, and clinical characteristics. Chronic heart failure is manifested by the toxic pathogens of turbid phlegm, stagnated blood, and accumulated fluid. Heart vessel obstruction is the main pathological factor, and the inflammatory factors produced by necrotic cardiomyocytes are the microscopic manifestations of the obstruction. Therefore, based on the "toxic pathogen theory", this study aimed to clarify the role of inflammation in the development of chronic heart failure from both macroscopic and microscopic perspectives. Moreover, this paper proposed that the stagnated blood has not been transformed into toxin in the early stage of the disease and thus the products of clearing heat and detoxification should not be used. At the development stage of the disease when the transformation tends to begin, treatment should be based on syndrome differentiation, and detoxifying Chinese medicine should be used in order to achieve the goal of "removing toxin without harming the healthy Qi". At the late stage of heart failure, toxins have been accumulated and detoxifying medicines and therapies should be applied to eliminate the toxic pathogens. This study is expected to lay a foundation for the modern research on the role of inflammation in the development of chronic heart failure with TCM theory and guide the diagnosis and treatment of this disease.

RESUMEN
ObjectiveTo systematically analyze the chemical components of QiLing Wenshen (QLWS) formula and explore the key active components and mechanism of the formula in the treatment of polycystic ovary syndrome (PCOS). MethodThe chemical components of QLWS formula were systematically identified by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MSE) combined with comparison with reference substances, literature data, and databases. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and SwissADME were employed to screen the active components for network pharmacological analysis. SwissTargetPrediction, GeneCards, DisGeNET, and DrugBank were used to obtain the potential components and targets of the formula for the treatment of PCOS. The protein-protein interaction (PPI) network was constructed via STRING database for further screening of the core targets. Gene ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of core targets were carried out with DAVID database. Molecular docking was performed in MOE 2019. ResultA total of 90 components of QLWS formula were identified, and 32 active components and 45 core targets for treating PCOS were obtained. GO annotation obtained 429 terms and KEGG pathway enrichment screened out 110 signaling pathways, mainly involving phosphatidylin-ositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, estrogen signaling pathway, and hypoxia inducible factor-1 (HIF-1) signaling pathway. The molecular docking revealed that key active components in QLWS formula were icariin, salvianolic acid A\B\C, wogonin, magnoflorine, etc., which may play a role in treating PCOS through regulating mitogen-activated protein kinase 1 (MAPK1), epidermal growth factor receptor (EGFR), mitogen-activated protein kinase 3 (MAPK3), etc. ConclusionThis study preliminarily predicted that several key active components of QLWS formula could treat PCOS via multiple targets and multiple pathways based on UPLC-Q-TOF/MSE and network pharmacology, which could provide ideas and references for the study of pharmacodynamic material basis and mechanism of action of the formula.
RESUMEN
Hyperthyroidism is a systemic disease characterized by clinical signs and symptoms of hypermetabolism and sympathetic nervous excitement. Based on the clinical diagnostic criteria of traditional Chinese and western medicine for hyperthyroidism,the present study summarized and evaluated animal models of hyperthyroidism. In model evaluation,the models with high coincidence degree in western medicine included the exogenous drug delivery model, the model immune to adenovirus expressing thyrotropin receptor (TSHR),the model immune to nucleic acid, and the model of yin deficiency and effulgent fire syndrome in the disease-syndrome combination. The models with high coincidence degrees in traditional Chinese medicine included the exogenous drug delivery model, the model immune to adenovirus expressing TSHR,and the model of liver-yang ascendant hyperactivity syndrome and the model of yin deficiency and effulgent fire syndrome in the disease-syndrome combination. In light of the coincidence degree, and advantages and disadvantages of traditional Chinese and western medicine,the ideal hyperthyroidism animal models are the exogenous drug delivery model, and the model immune to adenovirus expressing TSHR. In addition to the evaluation of the coincidence degree of animal models of hyperthyroidism in traditional Chinese and western medicine,this study also analyzed the advantages,disadvantages, and problems of the animal models of hyperthyroidism. Most of the animal models of hyperthyroidism were not consistent with the complexity of hyperthyroidism in clinical practice, and standardized and unified syndrome differentiation standards and four-examination information collection standards have not yet been formed. Besides, there have been few studies on the hyperthyroidism model in disease-syndrome combination in traditional Chinese medicine. To make the animal models of hyperthyroidism suitable for clinical practice,the present study proposed the improvement directions of animal models of hyperthyroidism and the necessity of promoting the evaluation system to provide a theoretical basis for the evaluation of the curative effect of Chinese medicine on hyperthyroidism, and exploration of its pharmacological action, as well as the follow-up research on the pathogenesis,prevention, and treatment of hyperthyroidism,which is expected to establish a perfect disease-syndrome model of hyperthyroidism in line with clinical characteristics of traditional Chinese and western medicine.
RESUMEN
ObjectiveTo observe the difference in the efficacy of three kinds of traditional Chinese medicine (TCM) injections on rat model of heart failure induced by transverse aortic constriction (TAC), explore the TCM syndrome of the model based on the theory of correspondence of prescription and syndrome, and reveal the biological basis of prescription-syndrome from the perspective of metabolism. MethodRats were treated with TAC for modeling and were divided into Shenmai injection group (6.0 mL·kg-1), model group, Danhong injection group (6.0 mL·kg-1), Shenfu injection group (6.0 mL·kg-1) and trimetazidine group (10 mg·kg-1), and sham operation group was set up as control. After drug intervention for 15 days, echocardiography, serum N-terminal pro-brain natriuretic peptide (NT-proBNP) and myocardial histopathological staining were performed for each group, so as to compare the efficacy to select the effective injection. Colorimetry was used to detect the serum glucolipid metabolism after the intervention of the effective injection, and ultra high performance liquid chromatography-mass spectrometry was used to observe the metabolites and related metabolic pathways in myocardial tissue. ResultCompared with the sham operation group, the left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (FS) in the model group decreased (P<0.01), while the left ventricular end-diastolic diameter (LVIDd), left ventricular internal diameter at end-systole (LVIDs) and NT-proBNP level increased (P<0.01). Compared with model group, LVEF and FS increased (P<0.01), LVIDd, LVIDs and NT-proBNP level decreased (P<0.05, P<0.01) in Danhong injection group, NT-proBNP level in Shenfu injection group decreased (P<0.05), LVIDd and NT-proBNP level increased (P<0.05, P<0.01) in Shenmai injection group, in trimetazidine group, LVEF and FS increased (P<0.01), while LVIDs and NT-proBNP level decreased (P<0.05, P<0.01). Serum glucose, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol levels in Danhong injection group and trimetazidine group were adjusted by callbacks (P<0.01, P<0.05). There were the callback of 9 myocardial metabolites in Danhong injection group, including glycine, serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, glycerol phospholipid metabolism. There were the callback of 10 myocardial metabolites in trimetazidine group, including glycerol phospholipid metabolism. ConclusionThe efficacy of Danhong injection on heart failure model induced by TAC is significant and superior to Shenfu injection and Shenmai injection, suggesting that the model is closely related to heart-blood stasis. The biological mechanism of Danhong injection interfering with the model involves regulating the metabolic disorder of lipid, glucose, amino acid and butyric acid.
RESUMEN
Nasal preparations have unique advantages in drug delivery and are widely used in the treatment of local and systemic diseases. Nasal administration of traditional Chinese medicine (TCM) has a long history in China. In recent years, nasal preparations of TCM have attracted wide attention. Based on the information about nasal preparations of TCM from the database of National Medical Products Administration (NMPA), Yaozh.com and China National Knowledge Internet (CNKI) in the recent 30 years, the formulation, the listed products, commonly used TCM, pharmaceutical excipients, clinical application and safety research of modern nasal preparations of TCM were summarized and expounded. Focusing on many problems in the development of modern nasal preparations of TCM, such as inaccurate dosage of some products, incomplete quality standard system of pharmaceutical excipients, imperfect safety evaluation, lack of research and development of nasal drug delivery devices and so on, the possible solutions and prospects were put forward from the aspects of optimizing the extraction and separation process of TCM, the quality control and application method of pharmaceutical excipients, the development of new dosage forms, the safety evaluation of nasal administration of TCM, and the design and development of nasal administration devices. The aim is to provide ideas for the development of nasal preparations of TCM and provide scientific basis for its sustainable utilization.
RESUMEN
ObjectiveTo study the efficacy of Aclasta combined with Liuwei Dihuangwan on osteoporosis and the effect on quality of life. MethodA total of 126 patients with osteoporosis who were treated in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September 2019 to September 2020 were classified into the observation group and the control group with the randomized double-blind method. The observation group consisted of 60 patients (26 males and 34 females) with the age of 59-85 years old [mean: (72.0 ± 6.5) years old]. The control group was composed of 66 patients (31 males and 35 females), with the age of 62-82 years old [mean: (73.0±8.2) years old]. The control group was treated with Aclasta, and the observation group Aclasta combined with Liuwei Dihuangwan. After treatment, the effective rate of each group was calculated. Bone mineral density (BMD) was measured in both groups before and after treatment, and serological parameters calcium (Ca), total 25 (OH) vitamin D3 (VITD-T), osteocalcin (OC), serum alkaline phosphatase (ALP), parathyroid hormone (PTH), β-collagen special sequence (β-CTX), and total procollagen 1 N-terminal propeptide (T-P1NP) were also measured. Visual Analogue Scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and Oswestry Disability Index (ODI) score were evaluated. On this basis, the effect was compared between the two groups. ResultThe indexes were insignificantly different between the two groups before treatment. After 6 months of treatment, the two groups showed decrease in VAS score and ODI score (P<0.01), increase in JOA score (P<0.01), BMD of lumbar spine and hip joint, elevation of Ca, VITD-T, OC, ALP, and PTH (P<0.05, P<0.01), and decrease of β-CTX (P<0.01) as compared with before treatment. The level of T-P1NP dropped in the observation group after treatment (P<0.01).After treatment, the total effective rate of the observation group was 88.3% (53/60), as compared with the 74.2% (49/66) in the control group (χ2=4.047, P<0.05). Moreover, after treatment, the observation group demonstrated higher levels of BMD, Ca, VITD-T, OC, and PTH (P<0.05), lower levels of T-P1NP (P<0.05), lower VAS score (P<0.01), and higher JOA score (P<0.05) than the control group, but the ODI score was insignificantly different from that in the control group. ConclusionAclasta combined with Liuwei Dihuangwan is effective on osteoporosis, without increasing the incidence of adverse reactions. In addition, the combination can alleviate pain and improve the quality of life of osteoporosis patients.
RESUMEN
Objective:To develop and test the reliability and validity of the assessment scale for patients with persistent vegetative state (PVS) or minimally conscious state (MCS) discharge from the anesthesia recovery room after operation.Methods:From September 2018 to October 2020, three dimensions and 17 item pools were determined through literature review and discussion among the project members. Two rounds of expert consultation were conducted to determine the respiratory (R), circulatory (C), oxygenation (O), bispectral index (B) and neuromuscular monitoring (N) scale (RCOBN scale), the reliability and validity were tested. 87 patients with PVS or MCS after operation Affiliated Sichuan Bayi Rehabilitation Center of Chengdu University of Traditional Chinese Medicine were selected to verify the effectiveness.Results:In the first round, 23 questionnaires were distributed. The total score of experts was 50 ± 3, F=9.24, CV were 0.00-0.43. The Cronbach α coefficient of each dimension was 0.782-0.846, and the Cronbach α coefficient of the total scale was 0.813. In the second round, 10 questionnaires were distributed. The item-level content validity index was 0.7-1.0, the probability of random consistency ( Pc) was 0.001-0.117, the adjusted kappa value ( k*) was 0.567-1.000, and the sum of the index scores corresponding to k* > 0.74 was 8. The scale-level content validity index of the overall consistency was 0.87. The ratio of patients transferred out of PACU by two rounds of evaluation method was 100 : 96.55, and the difference was not statistically significant ( χ2=3.05, P>0.05). The time of the first round of assessment was significantly longer than that of the second round, which were (197 ± 52) s and (58 ± 14) s respectively. The difference was statistically significant ( t=26.52, P < 0.01). Conclusions:The RCOBN scale has high reliability and validity. It can be used as an assessment scale for patients with PVS or MCS to transfer out of PACU after surgery, and those with a total score of 8 can be transferred out of PACU.
