ABSTRACT

Statins are a class of hydroxymethylglutaryl-CoA reductase inhibitors (HMG-CoA reductase inhibitors), which are widely used to reduce blood lipid in clinic, and are especially important for the prevention and treatment of cardiovascular diseases. In recent years, many studies at home and abroad believe that statins have a unique role in tumor prevention and treatment, and have been widely concerned. In terms of epigenetic regulation mechanism, statins mainly affect the progress of tumor through DNA methylation, histone modification and miRNA regulation. In addition, statins can also achieve their anti-tumor effects by promoting tumor cell autophagy, regulating tumor cell cycle, and promoting tumor cell apoptosis and other signaling pathways. Therefore, the research on statins provides ideas for the discovery of new anti-tumor treatments. In this paper, the role of statins in the prevention and treatment of common tumors is reviewed, including its mechanism of inhibiting the occurrence and development of tumors through epigenetic regulation and other related mechanisms, as well as its clinical research status.

ABSTRACT

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

ABSTRACT

ObjectiveTo explore the antidepressant effect of Sophora flavescens seed extract and its molecular mechanism. MethodA mouse depression model was established by intraperitoneal injection of lipopolysaccharide(LPS), and normal group, model group, fluoxetine group(2.5 mg·kg-1), and S. flavescens seed low, medium and high dose groups(200, 400, 800 mg·kg-1) were set up for 7 d of consecutive gavage. Then the antidepressant effect of S. flavescens seed extract was evaluated by using open field test, elevated plus maze test and forced swimming test. Pathological morphological changes in the hippocampal tissue was observed by hematoxylin-eosin(HE) staining. Protein expression levels of G1/S-specific cyclin D1(Cyclin D1), Wnt1, β-catenin and phosphorylated glycogen synthase kinase-3β(p-GSK-3β) in mouse brain tissues were detected by Western blot. Hippocampal cell apoptosis was detected by terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate(dUTP) nick end labeling(TUNEL). ResultThe results of mouse behavioral experiments showed that compared with the normal group, the speed of movement in the open field and the distance of movement in the central area of the open field, and the time spent on the open arms of the elevated plus maze were significantly reduced in the model group(P<0.01), while immobility time in the forced swimming test was significantly increased(P<0.05). Compared with the model group, the S. flavescens seed medium and high dose groups had increased speed of movement in the open field test and time spent on the open arms of the elevated plus maze test(P<0.05, P<0.01), and decreased immobility time in the forced swimming test(P<0.05), the distance of movement in the central area of the open field test increased in the high dose group(P<0.05). HE staining results showed that compared with the normal group, the hippocampal neuron structure of mice in the model group was damaged. Compared with the model group, after treatment of S. flavescens seed extract, the pathological state of the mouse hippocampal neuron structure was alleviated, and the neurons increased, were neatly arranged, and the cytoplasm was clear. Western blot results showed that the protein expression levels of Wnt1 and β-catenin in mouse brain tissue were significantly decreased(P<0.01), while the protein expression levels of Cyclin D1 and p-GSK-3β were significantly increased(P<0.01) after LPS injection. Compared with the model group, protein expression levels of Wnt1 and β-catenin in brain tissue of S. flavescens seed medium and high dose groups were significantly increased(P<0.01), while the protein expression levels of Cyclin D1 and p-GSK-3β were significantly decreased(P<0.01). TUNEL staining results showed that the hippocampal cell apoptosis rate in the model group was significantly increased compared with that of the normal group(P<0.01), while the hippocampal cell apoptosis rate in the S. flavescens seed medium and high dose groups was significantly decreased compared with that of the model group(P<0.01). ConclusionS. flavescens seed extract can effectively improve the severity of depression in LPS-induced depressed mice, and its molecular mechanism is related to the regulation of neuroinflammation and hippocampal neuronal apoptosis mediated by Wnt/β-catenin signaling pathway.

ABSTRACT

Infusion misdirection syndrome(IMS)is a rare and troublesome intraoperative complication during phacoemulsification cataract surgery, which usually occurs in hydrodissection, phacoemulsification or irrigation/aspiration(I/A). Under the factors of lax zonular fibers, lens dislocation, posterior capsular rupture, the anterior segment crowding, high perfusion pressure, the infusion fluid accumulates in the vitreous cavity or behind the vitreous, leading to intraocular hypertension, shallowness or even disappearance of the anterior chamber and eventually causing the suspension of surgery. It needs to be differentiated from suprachoroidal hemorrhage(SCH), capsular block syndrome(CBS), etc. After intraoperative emergency treatments, such as rest combined with intravenous drip of mannitol, pars plana needle aspiration or vitrectomy, a favorable prognosis can be obtained. This review discusses the pathogenesis, diagnosis, emergency management, prevention and prognosis of IMS during phacoemulsification cataract surgery, with the aim of providing clinical guidance for ophthalmologists.

ABSTRACT

Objective:To evaluate the efficacy of low-dose radiotherapy in patients with advanced hypopharyngeal cancer without high-risk factors.Methods:Clinical data of 235 patients diagnosed with advanced hypopharyngeal cancer treated in Department of Head and Neck Surgery of Shandong Provincial ENT Hospital from December 2013 to August 2018 were retrospectively analyzed. All patients were divided into two groups: low-dose radiotherapy group (50 Gy, n=158) and high-dose radiotherapy group (>60 Gy, n=77). Clinical baseline characteristics, treatment, follow-up and survival of patients were collected. Survival curve was delineated using the Kaplan-Meier method, and the differences in survival between two groups were calculated using the log-rank test. Clinical baseline characteristics between two groups were compared by χ2 test. Univariate and multivariate analyses of prognostic factors were conducted by logistic regression model. Results:The median follow-up time was 45 months (5-94 months). The 3-year overall survival (OS) rate of the whole group was 68.5%, and 70.3% and 64.9% in the low-dose and high-dose groups, respectively ( P=0.356). The 3-year progression-free survival (PFS) rate of the whole group was 64.3%, and 65.8% and 61.0% in the low-dose and high-dose groups, respectively ( P=0.361). Univariate analysis showed that T stage, N stage, lesion location and degree of pathological differentiation significantly affected clinical prognosis (all P<0.05), whereas there was no significant relationship between age, sex, radiotherapy dose, interval between surgery and radiotherapy and survival. Multivariate analysis showed that T stage, N stage and the degree of pathological differentiation were the independent prognostic factors (all P<0.05) of the 3-year OS and PFS. Sex, radiotherapy dose and interval between surgery and radiotherapy were not correlated with OS and PFS. Conclusion:This study showed that for hypopharyngeal cancer patients without positive surgical margins and extracapsular extension, postoperative radiotherapy at a dose of 50 Gy given to tumor bed and selective lymph node drainage area does not compromise local disease control and OS.

Objective: This study aimed to investigate the epidemiological characteristics of cardio-metabolic risk factors among children and adolescents aged 7-17 years in (Hebei, Zhejiang, Shaanxi, Hunan) 4 provinces of China and the influence of demographic and economic characteristics on them. Methods: A total of 1 747 children and adolescents aged 7-17 from a Community-based Cohort Study on Nervous System Disease in 2018 were selected. High waist circumference, central obesity, elevated TG, elevated TC, elevated LDL-C, decreased HDL-C, elevated blood pressure, elevated blood glucose, and clustering of risk factors was analyzed. χ2 test was used for univariate analysis, multivariate logistic regression was used to analyze the correlation between demographic and economic factors and risk factors, and the Cochran-Armitage trend test was used for trend analysis. Results: The detection rates of high waist circumference, decreased HDL-C, elevated blood pressure, elevated TG, elevated blood glucose, central obesity, elevated TC, and elevated LDL-C were 29.08%, 15.28%, 13.17%, 13.05%, 11.79%, 7.33%, 6.53%, and 5.15%, respectively. The rate of clustering of risk factors was 18.37%. Multivariate logistic regression analysis showed that the risk of high waist circumference in girls was higher than that in boys (OR=1.67, 95%CI: 1.26-2.22), and the risk of elevated blood glucose and clustering of risk factors was lower than that in boys (OR=0.69, 95%CI: 0.49-0.99; OR=0.72, 95%CI: 0.53-0.99). The risk of high waist circumference, decreased HDL-C, and clustering of risk factors in 13-17 years old group was higher than that in the 7-year-olds group (OR=2.24, 95%CI: 1.65-3.04; OR=1.59, 95%CI: 1.20-2.11; OR=1.75, 95%CI: 1.26-2.44), but the risk of central obesity was lower (OR=0.54, 95%CI: 0.37-0.78). The risk of elevated TC, elevated TG, and decreased HDL-C in children and adolescents in southern was higher than that in northern parts of China (OR=1.88, 95%CI: 1.25-2.83; OR=1.61, 95%CI: 1.17-2.22; OR=1.55, 95%CI: 1.19-2.04), but the risk of high waist circumference and central obesity was lower than that in northern China (OR=0.57, 95%CI: 0.43-0.75; OR=0.62, 95%CI: 0.42-0.90). The risk of decreased HDL-C in rural children and adolescents was higher than in urban children and adolescents (OR=1.36, 95%CI: 1.02-1.83). The risk of multiple risk factors increased with the increase in average monthly household income per capita and BMI level. Conclusions: High waist circumference, decreased HDL-C and elevated blood pressure were prominent cardio-metabolic risk factors among children and adolescents aged 7-17 years in 4 provinces of China in 2018. The region, average monthly household income per capita, and BMI were the main influencing factors of cardio-metabolic risk factors.

ABSTRACT

Objective: To explore the application of up-conversing phosphor technology (UPT) to detect pathogenic organisms in the air. Methods: The performance of UPT was verified with Staphylococcus aureus, Yersinia pestis and Escherichia coli O157 as simulated strains, including stability, specificity, sensitivity and response time tests; Air particle sampler is used to collect air samples in the field microenvironment test chamber, and UPT is used for detection. At the same time, compared with the traditional culture method, the practicability of UPT is verified. Results: The coefficient of variation in laboratory was 9.62% and 8.02% when the concentration of 107 CFU/ml and 108 CFU/ml were detected by UPT. The results were less than the allowable target, and the detection system had good stability. The specificity of UPT was verified by Staphylococcus aureus. The results showed that no non-Staphylococcus aureus was detected, and the positive detection rate of different kinds of Staphylococcus aureus was 100%. The specificity of the detection system was good. The sensitivity of UPT for detecting Staphylococcus aureus was 104 CFU/ml. Detection sensitivity of Yersinia pestis ≥103 CFU/ml; The detection sensitivity of Escherichia coli O157 is ≥103 CFU/ml, and the response time of UPT to bacteria is within 15 min (all 10 min 15 s). The detection results of bacteria contentration in the air of the on-site microenvironment test cabin by UPT showed that when the concentration of Escherichia coli O157 in the air reached above 104 CFU/m3, the detection results of UPT were positive, and with the increase of air concentration, the numerical concentration measured by UPT showed an upward trend, which was positively correlated with the concentration of bacteria in the air. Conclusion: UPT may be feasible as a rapid method to evaluate the species and contentration of pathogenic organisms in the air.

ABSTRACT

OBJECTIVE@#To study the expression level of nicotinamide phosphoribosyltransferase (NAMPT) in multiple myeloma (MM), its relationship with clinical indicators, prognosis and potential role.@*METHODS@#Immunohistochemical staining was used to detect the expression of NAMPT in bone marrow biopsies of patients with newly diagnosed multiple myeloma (NDMM) and patients with iron deficiency anemia (IDA) hospitalized during the same period. According to the median expression level of NAMPT, NDMM patients were divided into high expression group and low expression group. The correlation between NAMPT expression level and clinical baseline data was analyzed, and survival analysis was performed to evaluate the relationship between NAMPT expression level and prognosis. The GSE24080 and GSE19784 datasets were used to analyze the effect of NAMPT on the prognosis. Gene set enrichment analysis (GSEA) explored the possible mechanism of NAMPT involved in MM cell function.@*RESULTS@#The mean staining intensity of NAMPT in bone marrow tissue of 31 NDMM patients was 0.007±0.002, and that of 10 IDA patients was 0.002±0.002 (P < 0.05). The median expression level of NAMPT was 0.0041 in NDMM patients, and the mean staining intensity of high expression group and low expression group was 0.007±0.005 and 0.002±0.001, respectively (P < 0.001). There were certain differences in lactate dehydrogenase (LDH), C-reactive protein (CRP) and ISS staging between high expression group and low expression group (P < 0.001), while no significant differences in other indicators. The overall response rate (ORR) of high expression group was significantly lower than that of low expression group (P < 0.001). The median survival time of patients in high expression group was significantly shorter than that in low expression group (P =0.024). The results of bioinformatics analysis showed that the event-free survival (EFS) rate and overall survival (OS) rate of low NAMPT group were both higher than high NAMPT group (P =0.037, P =0.009), and NAMPT was an independent prognostic factor for EFS and OS (P =0.006, P =0.020). GSEA suggested that NAMPT might affect MM cell function through mTORC1 signaling pathway.@*CONCLUSIONS@#The expression level of NAMPT in bone marrow of NDMM patients is significantly higher than that of IDA patients, and the high expression of NAMPT may be correlated with late ISS stage, and high level of LDH and CRP. Patients with high expression of NAMPT have worse response to bortezomib and survival time may be shorter. NAMPT may be involved in the occurrence and development of MM through mTORC1 signaling pathway.

ABSTRACT

Multiple myeloma (MM) is a common plasma cell malignancy, accounting for the second largest hematological malignancy. Proteasome inhibitors represented by bortezomib (BTZ) have been the main treatment for patients with newly diagnosed and relapsed or refractory myeloma in nearly two decades. Although BTZ has improved the prognosis of MM patients, MM remains incurable in most patients, mainly because MM cells become resistant to BTZ. This review is to better understand the mechanism of MM resistance to BTZ and explore possible new therapeutic strategies.

ABSTRACT

Diabetic peripheral neuropathy(DPN) is a chronic complication resulted from peripheral nerve injury in the late stage of diabetes. It involves a variety of pathological changes such as oxidative stress, endoplasmic reticulum stress, neuroinflammation, and apoptosis of Schwann cells(SCs). DPN is the main factor leading to lower limb disability or amputation in diabetic patients, with high incidence, long disease course, and poor prognosis. The modern medicine treatment of DPN mainly focuses on controlling blood glucose and improving microcirculation and nerve nutrition, which can only mitigate the clinical symptoms and not fundamentally reverse the pathological changes of peripheral nerves. Autophagy is a self-clearing mechanism that maintains cellular homeostasis by removing excess metabolites. Traditional Chinese medicine(TCM), featuring the holistic concept and syndrome differentiation, can treat chronic diseases in a multi-target, multi-pathway, and wide-range manner. Modern studies have shown that the occurrence and development of DPN are related to a variety of pathological changes, and autophagy is a key mechanism associated with DPN. The environment with persistent high glucose can lead to the inhibition or over-activation of peripheral nerve cells, which causes irreversible damage of nerve cells and the occurrence and development of DPN. Therefore, restoring autophagy balance and reducing nerve damage is one of the key ways to treat DPN. The recent studies have confirmed that some active ingredients in traditional Chinese medicines and TCM compound prescriptions can inhibit the oxidative stress, endoplasmic reticulum stress, mitochondrial damage, inflammation, and apoptosis of SCs in DPN by regulating the autophagy pathway, thus playing a role in the prevention and treatment of DPN. However, the systematic induction in this field remains to be carried out. This paper reviewed the relevant literature, explained the mechanism of TCM in the prevention and treatment of DPN by regulating autophagy, and summarized the potential targets of TCM in the treatment of DPN, with a view to providing new ideas for clinical research and drug development.

ABSTRACT

This study aims to investigate the intervention effect of the aqueous extract of Epimedium sagittatum Maxim on the mouse model of bleomycin(BLM)-induced pulmonary fibrosis, so as to provide data support for the clinical treatment of pulmonary fibrosis. Ninety male C57BL/6N mice were randomized into normal(n=10), model(BLM, n=20), pirfenidone(PFD, 270 mg·kg~(-1), n=15), and low-, medium-, and high-dose E. sagittatum extract(1.67 g·kg~(-1), n=15; 3.33 g·kg~(-1), n=15; 6.67 g·kg~(-1), n=15) groups. The model of pulmonary fibrosis was established by intratracheal instillation of BLM(5 mg·kg~(-1)) in the other five groups except the normal group, which was treated with an equal amount of normal saline. On the day following the modeling, each group was treated with the corresponding drug by gavage for 21 days. During this period, the survival rate of the mice was counted. After gavage, the lung index was calculated, and the morphology and collagen deposition of the lung tissue were observed by hematoxylin-eosin(HE) and Masson staining, respectively. The levels of reactive oxygen species(ROS) in lung cell suspensions were measured by flow cytometry. The levels of glutathione peroxidase(GSH-Px), total superoxide dismutase(T-SOD), and malondialdehyde(MDA) the in lung tissue were measured. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling(TUNEL) was employed to examine the apoptosis of lung tissue cells. The content of interleukin-6(IL-6), chemokine C-C motif ligand 2(CCL-2), matrix metalloproteinase-8(MMP-8), transforming growth factor-beta 1(TGF-β1), alpha-smooth muscle actin(α-SMA), E-cadherin, collagen Ⅰ, and fibronectin in the lung tissue was measured by enzyme-linked immunosorbent assay(ELISA). The expression levels of F4/80, Ly-6G, TGF-β1, and collagen Ⅰ in the lung tissue were determined by immunohistochemistry. The mRNA levels of CCL-2, IL-6, and MMP-7 in the lung tissue were determined by qRT-PCR. The content of hydroxyproline(HYP) in the lung tissue was determined by alkaline hydrolysation. The expression of α-SMA and E-cadherin was detected by immunofluorescence, and the protein levels of α-SMA, vimentin, E-cadherin in the lung tissue were determined by Western blot. The results showed the aqueous extract of E. sagittatum increased the survival rate, decreased the lung index, alleviated the pathological injury, collagen deposition, and oxidative stress in the lung tissue, and reduced the apoptotic cells. Furthermore, the aqueous extract of E. sagittatum down-regulated the protein levels of F4/80 and Ly-6G and the mRNA levels of CCL-2, IL-6, and MMP-7 in the lung tissue, reduced the content of IL-6, CCL-2, and MMP-8 in the alveolar lavage fluid. In addition, it lowered the levels of HYP, TGF-β1, α-SMA, collagen Ⅰ, fibronectin, and vimentin, and elevated the levels of E-cadherin in the lung tissue. The aqueous extract of E. sagittatum can inhibit collagen deposition, alleviate oxidative stress, and reduce inflammatory response by regulating the expression of the molecules associated with epithelial-mesenchymal transition, thus alleviating the symptoms of bleomycin-induced pulmonary fibrosis in mice.

ABSTRACT

Obesity has been identified as a chronic low-grade systemic inflammation and a key risk factor for diseases such as diabetes, hypertension, and malignancies, and has become an urgent global health burden. Adipose tissue macrophages play a significant role in adipose immune homeostasis and inflammatory responses. Under different conditions, they can be polarized into pro-inflammatory M1 phenotype or anti-inflammatory M2 phenotype. In obese individuals, there is abnormal polarization of macrophages in adipose tissue, leading to an imbalance in the M1/M2 phenotype dynamic equilibrium and the development of pathological inflammation. Therefore, restoring the balance of M1/M2 macrophage polarization is an important potential target for the treatment of chronic inflammation in obesity. Studies have shown that traditional Chinese medicine(TCM) can positively modulate macrophage polarization and produce beneficial effects on obesity. Based on existing evidence, this paper systematically reviewed the potential mechanisms of TCM in improving chronic inflammation in obesity from the perspective of macrophage polarization, in order to provide evidence for the clinical diagnosis and treatment of chronic inflammation in obesity with TCM and offer new insights for related research design and the development of new TCM.

ABSTRACT

Alkaloids are important active ingredients occurring in many traditional Chinese medicines, and alkaloid glycosides are one of their existence forms. The introduction of saccharide units improves the water solubility of alkaloid glycosides thus presenting better biological activity.Because of the low content in plants, alkaloid glycosides have been not comprehensively studied. In this study, ultrahigh performance liquid chromatography-quadrupole time of flight-tandem mass spectrometry(UPLC-QTOF-MS/MS) was employed to identify and analyze the alkaloid glycosides in Coptis chinensis, Phellodendron chinense, Menispermum dauricum, Sinomenium acutum, Tinospora sagittata and Stephania tetrandra. The results showed that except Tinospora sagittata, the other five herbal medicines contained alkaloid glycosides. Furthermore, the alkaloid glycosides in each herbal medicine were identified based on UV absorption spectra, quasimolecular ion peaks in MS, fragment ions information in the MS/MS, and previous literature reports. A total of 42 alkaloid glycosides were identified. More alkaloid glycosides were identified in C. chinensis and Menispermum dauricum, and eleven in C. chinensis were potential new compounds. Furthermore, the alkaloid glycosides in the water extract of C. chinensis were coarsely se-parated by macroporous adsorption resin, purified by column chromatography with D151 cation exchange resin, ODS and MCI, combined with semi-preparative high performance liquid chromatography. Two new alkaloid glycosides were obtained, and their structures were identified by mass spectrometry and NMR data as(S)-7-hydroxy-1-(p-hydroxybenzyl)-2,2-N,N-dimethyl-1,2,3,4-tetrahydroisoquinoline-6-O-β-D-glucopyranoside and(S)-N-methyltetrahydropalmatubine-9-O-β-D-glucopyranoside, respectively. This study is of great significance for enriching the information about the chemical composition and the in-depth development of C. chinensis. Meanwhile, it can provide a reference for rapid identification and isolation of alkaloid glycosides from other Chinese herbal medicines.

ABSTRACT

The shortage of Paridis Rhizoma promotes comprehensive utilization and development research of waste aerial parts of the original plant. The chemical compositions of the aerial parts of Paris polyphylla var. chinensis were clarified based on the ultrahigh performance liquid chromatography tandem quadrupoles time of flight mass spectrometry(UPLC-QTOF-MS/MS) in the previous investigation, and a series of flavonoids and steroidal saponins were isolated. The present study continued the isolation and structure identification of the new potential compounds discovered based on UPLC-QTOF-MS/MS. By using silica gel, ODS, flash rapid preparation, and other column chromatography techniques, combined with prepared high performance liquid chromatography, five compounds were isolated from the 75% ethanol extract of the aerial parts of P. polyphylla var. chinensis, and their structures were identified by spectral data combined with chemical transformations, respectively, as(23S,25R)-23,27-dihydroxy-diosgenin-3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside(1),(25R)-26-O-β-D-glucopyranosyl-furost-5-en-3β,22α,26-triol-3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)]-β-D-glucopyranoside(2),(25R)-27-O-β-D-glucopyranosyl-5-en-3β,27-dihydroxyspirost-3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)]-β-D-glucopyranoside(3),(25R)-27-O-β-D-glucopyranosyl-5-en-3β,27-dihydroxyspirost-3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranoside(4), and aculeatiside A(5). Among them, compounds 1-4 were new ones, and compound 5 was isolated from P. polyphylla var. chinensis for the first time.

ABSTRACT

OBJECTIVE@#To analyze the expression level of nicotinamide phosphoribosyltransferase (NAMPT ) in bone marrow of multiple myeloma (MM) patients and its correlation with clinicopathological features, clinical efficacy and prognosis.@*METHODS@#RT-qPCR and Western blot were used to detect the expression of NAMPT mRNA and protein in bone marrow mononuclear cells from 85 newly diagnosed MM patients (including 17 relapsed MM patients) and 15 healthy donors, and explore the correlation of the expression of NAMPT gene with clinicopathological features and efficacy. Kaplan-Meier method was used to analyze the effects of NAMPT on progression-free survival (PFS) and overall survival (OS), and univariate and multivariate survival analysis were performed.@*RESULTS@#The median expression level of NAMPT mRNA in bone marrow of newly diagnosed and relapsed MM patients was significantly higher than that of healthy donors (P <0.001). The expression of NAMPT mRNA in relapsed MM patients was significantly higher than that in newly diagnosed MM patients (P <0.001), which was consistent with the expression of NAMPT protein. ISS staging, lactate dehydrogenase and C-reactive protein levels, p53 deletion and the proportion of myeloma cells were increased in high NAMPT expression group compared with low NAMPT expression group (P <0.001). Compared with complete remission group, NAMPT mRNA expression was significantly up-regulated in partial remission group, progression group and relapsed group (P <0.001). The median OS and PFS of patients in high NAMPT expression group was 27.3 and 14.9 months, respectively, which was significantly shorter than 39.1 and 27 months in low NAMPT expression group (P =0.048, P <0.001). Both univariate and multivariate analysis showed that NAMPT expression was correlated with PFS and OS.@*CONCLUSION@#The expression level of NAMPT in newly diagnosed and relapsed MM patients is significantly higher than that in normal controls, and its up-regulation is related to the adverse clinical characteristics, efficacy and prognosis of MM patients. NAMPT is an independent prognostic risk factor of MM.

ABSTRACT

Objective To explore the effect of air temperature on the hospitalization of rural residents with cardiovascular diseases and its lag effect in Dingxi city. Methods The meteorological data and air pollution data of Dingxi city from 2018 to 2019,as well as the daily hospitalization data of rural residents due to cardiovascular diseases,were collected.The distributed lag non-linear models were employed to analyze the relationship between daily mean air temperature and the number of inpatients with cardiovascular diseases.Meanwhile,stratified analysis was carried out according to gender,age,and disease. Results There was a non-linear relationship between air temperature and the number of hospitalized rural residents with cardiovascular diseases in Dingxi city.The exposure-response curve approximated a bell shape.The curves for different cardiovascular diseases appeared similar shapes,with different temperature thresholds.Low temperature(-7 ℃) and moderately low temperature(0 ℃) exhibited a cumulative lag effect on the number of patients hospitalized with cardiovascular diseases.With a cumulative lag of 7 days at -7 ℃ and 14 days at 0 ℃,the RR values peaked,which were 1.121(95% CI=1.002-1.255) and 1.198(95% CI=1.123-1.278),respectively.With a cumulative lag of 14 days at 0 ℃,the RR values were 1.034(95% CI=1.003-1.077) and 1.039(95% CI=1.004-1.066) for the number of hospitalized patients with ischemic heart disease and heart rhythm disorders,respectively.The cumulative lag effects of moderately high temperature(17 ℃) and high temperature(21 ℃) on ischemic heart disease,heart rhythm disorders,and cerebrovascular disease all peaked on that day.Specifically,the RR values at 17 ℃ and 21 ℃ were 1.148(95% CI=1.092-1.206) and 1.176(95% CI=1.096-1.261) for ischemic heart disease,1.071(95% CI=1.001-1.147) and 1.112(95% CI=1.011-1.223) for heart rhythm disorders,and 1.084(95% CI=1.025-1.145) and 1.094(95% CI=1.013-1.182) for cerebrovascular disease,respectively.There was no cumulative lag effect of air temperature on the number of hospitalized patients with heart failure.In addition,stratified analysis showed that low temperature(-7 ℃) and moderately low temperature(0 ℃) affected the number of hospitalized female patients with cardiovascular diseases,and only moderately low temperature(0 ℃) affected males.The cumulative lag effect of high temperature on females was higher than that on males.Air temperature exhibited a stronger impact on female patients than on male patients. Additionally,the population aged<65 years old was more sensitive to low temperature and high temperature than that aged ≥65 years old. Conclusions Air temperature changes increase the hospitalization risk of rural residents with cardiovascular diseases in Dingxi city,which presents a lag effect.The effects of air temperature on patients hospitalized due to cardiovascular diseases varied among different etiologies,genders,and ages.It is necessary to emphasize on the impact of temperature changes on health in residents,especially for key populations such as females,people aged<65 years old,and those with ischemic heart disease.

ABSTRACT

Objective To investigate the correlation between the polymorphism of 5,10-methylenetetrahydrofolate reductase ( MTHFR) gene rs!801131 and hypertensive disorders complicating pregnancy ( HDCP ) in Qinghai Han nationality. Methods The polymorphism of MTHFR rsl801131 in 120 pregnant women with HDCP (HDCP group) and 120 normal pregnant women ( control group) were detected by restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP) and verified by sequencing. Results The frequencies of AA, AC, and CC genotype of MTHFR gene in the HDCP group were 56. 67% , 32. 50% , and 10. 83% respectively, and those in the control group were 74.17%, 23.33% and 2. 50% respectively (P<0. 05, the distribution of genotype was different significantly between the two groups). The frequency of AA genotype of HDCP group (56. 67%) was lower than that of control group (74. 17%, P<0. 05) , the frequency of CC genotype of HDCP group ( 10. 83%) was higher than that of control group ( 2. 50% , P< 0. 05) , while there was no significant difference in the frequency of AC genotype between HDCP group and control group ( P<0. 05). The frequency distribution of alleles A and C of MTHFR rsl801131 polymorphism was significantly different between the HDCP group and the control group (P<0. 001) , and the frequency of allele C in the HDCP group was significantly higher than that in the control group (X2 = 12. 229, 0R=L 574, 95% C/= 1. 181-2. 099, P<0. 001). Conclusion The polymorphism of MTHFR rsl801131 is related to the occurrence of HDCP in Qinghai Han population. The C gene might be the susceptibility gene of HDCP, and CC genotype might be the susceptibility genotype of HDCP.

ABSTRACT

The rhizome of giant taro (Alocasia macrorrhiza (L.) Schott), which is a highly adaptable wild plant, is a traditional Chinese herbal medicine. In the current study, the antiproliferative constituents of giant taro were investigated and six new (1-6) and four known piperidine alkaloids (7-10) were isolated from its rhizomes. Their chemical structures and absolute configurations were elucidated using various spectroscopic methods and the Mosher ester method. The isolated alkaloids were screened for the antiproliferative activity through MTT assay. The results indicated that piperidine alkaloids exerted potential antiproliferative activity against HepG2, AGS and MCF-7 tumor cells. Further researches showed that compounds 3-5 dose-dependently decreased the colony formation rate and induced the apoptosis of AGS cells, while compound 4 induced AGS cell death via the proapoptotic pathway. This study demonstrates that the piperidine alkaloids isolated from giant taro exhibit significant antitumor activity, which provides phytochemical evidence for further development and utilization.

ABSTRACT

OBJECTIVE@#To summarize the medication rules of Chinese herbs to treat heart failure with preserved ejection fraction (HFPEF) based on data mining and to provide references for clinical utilization.@*METHODS@#The China National Knowledge Infrastructure (CNKI), Wanfang database (Wanfang), VIP database (VIP), Chinese Biomedical Literature (CBM), PubMed, Embase, and Cochrane Library databases were searched from inception to October 2021 to identify relevant literature on treating HFPEF with Chinese herbs. Microsoft Excel 2019 was used to set up a database, and then, association rule analysis and hierarchical cluster analysis were performed by using apriori algorithm and hclust function respectively in R-Studio (Version 4.0.3).@*RESULTS@#A total of 182 qualified papers were included, involving a total of 92 prescriptions, 130 Chinese herbs, and 872 individual herbs prescribed, with an average of 9.5 herbs per prescription. The six most frequently prescribed herbs were Astragali Radix (Huangqi), Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Glycyrrhizae Radix Et Rhizoma (Gancao), Cinnamomi Ramulus (Guizhi), and Ginseng Radix Et Rhizoma (Renshen). There were 35 herbs used more than 5 times, involving 11 efficacy categories. The top three categories were deficiency-tonifying herbs, blood-activating and stasis-removing herbs, and dampness-draining diuretic herbs. The most commonly used herbs were mainly warm and sweet. The primary meridian tropisms were Lung Meridian, Heart Meridian and Spleen Meridian. Association rule analysis yielded 26 association rules, such as Astragali Radix (Huangqi) & Salviae Miltiorrhizae Radix Et Rhizoma (Danshen), Poria (Fuling), Cinnamomi Ramulus (Guizhi) & Atractylodis Macrocephalae Rhizoma (Baizhu). Hierarchical cluster analysis yielded four herb classes, and their functions were mainly qi-replenishing and yang-warming, blood-activating and diuresis-inducing.@*CONCLUSIONS@#HFPEF is the syndrome of root vacuity and tip repletion, and its core pathogenesis is "deficiency", "stasis", and "water", with "deficiency" being the most principal, which is closely related to Xin (heart), Fei (Lung), and Pi (Spleen). The treatment of this disease occurs by improving qi, warming yang, activating blood and inducing diuresis. Astragali Radix (Huangqi) with Salviae Miltiorrhizae Radix Et Rhizoma (Danshen) is the basic combination of herbs applied.
