ABSTRACT

Licorice, one of the most commonly used medicinal materials in China, grows mainly in arid and semi-arid regions and has important economic and ecological values. Basic leucine zipper (bZIP) transcription factors in plants play an important role in regulating biological or abiotic stress responses, growth, and secondary metabolite synthesis. bZIP transcription factors in the published whole genome database of Glycyrrhiza uralensis were identified using bZIP sequences found in Arabidopsis thaliana genome as reference, and ABA-dependent bZIP genes were identified by using Illumina high-throughput sequencing. The physical and chemical properties, structure of the encoded proteins, and the gene expression patterns with exogenous ABA stress were analyzed. A total of 69 bZIP transcription factor genes were identified in G. uralensis, named Gubzip1-69, and they were divided into 10 subfamilies (A-I and S) according to their similarity to bZIPs of A. thaliana. By calculating the relative expression levels of the 69 GubZIPs genes under different concentrations of exogenous ABA stress, genes that may be involved in the regulation of ABA signaling pathways were identified, namely GubZIP1, GubZIP5, GubZIP8, GubZIP30, GubZIP33 and GubZIP56. The results of expression pattern analysis of these GubZIPs genes under exogenous ABA stress showed that the expression pattern of GubZIPs genes changed significantly with 50 mg·L-1 ABA. The relative expression levels of these genes decreased 3 h after treatment, and gradually increased 6 h after treatment. Except for GubZIP8, the relative expression levels of these genes were significantly increased after 12 h. Further research on the function of bZIP transcription factors of G. uralensis and elucidating their regulatory mechanisms should be of interest and will provide a scientific basis for cultivating high-quality cultivars of G. uralensis through molecular breeding methods.

ABSTRACT

Traditional Chinese medicine (TCM) and western medicine have their respective advantages and limitations in the diagnosis and treatment of common otorhinolaryngology head and neck diseases. Although the integrated TCM and western medicine exhibits definite curative effects, there is no consensus on the otorhinolaryngology head and neck diseases responding specifically to TCM or integrated TCM and western medicine, as well as the diagnosis and treatment schemes. The China Association of Chinese Medicine (CACM) thus organized the otorhinolaryngology head and neck specialists of both TCM and western medicine to discuss the etiology, pathogenesis, and clinical diagnosis and treatment methods of common otorhinolaryngology head and neck diseases with the results of multiple clinical trials taken into account. The acute pharyngitis, chronic pharyngolaryngitis, paraesthesia pharyngis, hysterical aphasia, allergic rhinitis, subjective tinnitus, and otogenic vertigo were confirmed to respond specifically to TCM or integrated TCM and western medicine. Then a mutually agreed diagnosis and treatment scheme and recommendation with integrated TCM and western medicine was formulated as a reference for clinical practice, thus benefiting more patients.

ABSTRACT

Objective To understand the current status of osteoporosis risk and influencing factors for residents from 30 to 65 years old in typical hot spring areas in Guizhou province, and to provide a theoretical basis for reducing the risk of osteoporosis and the prevention of osteoporosis in the population. Methods A health questionnaire for residents in typical hot spring areas in Guizhou, osteoporosis risk test questions, Pittsburgh sleep quality index(PSQI), etc were used. A face-to-face survey of 3 708 residents was conducted, and logistic regression was used to analyze the influencing factors of osteoporosis risk in hot spring areas. Results 2 403(64.81%)residents of 3 708 people surveyed were at risk of osteoporosis, of whom 1 434(87.4%)males and 969 females(47.1%)had a higher risk of osteoporosis (χ2=652.4, P < 0.001). As age increased, more residents were at risk of osteoporosis(χ2=273.4, P < 0.001), and numbers of residents of 30-39 years old, 40-59 years old, and above 60 years of age at risk of osteoporosis were 319(49.2%), 1 572(62.9%), and 512(93.6%). Male osteoporosis risk was negatively correlated with an education level of undergraduate and above(OR=0.37, 95%CI: 0.19-0.73). Age 40-59(OR=1.54, 95%CI: 1.07-2.22), 60 and above(OR=6.39, 95%CI: 2.76-14.79), and sleep disorders(OR=1.59, 95%CI: 1.08-2.35)may increase the risk of osteoporosis in male residents in hot spring areas. Less oil in daily diet may increase the risk of osteoporosis in women(OR=1.70, 95%CI: 1.23-2.36). Age 40-59(OR=1.54, 95%CI: 1.17-2.03), over 60 and above(OR=16.24, 95%CI: 10.10-26.12), and sleep disorders(OR=1.84, 95%CI: 1.48-2.28)were positively correlated with risk of osteoporosis in women. Women with junior high school degree(OR=0.61, 95%CI: 0.47-0.80), high school degree(OR=0.57, 95%CI: 0.37-0.89)and undergraduate degree and above(OR=0.59, 95%CI: 0.39-0.98)had a lower risk of osteoporosis than women who were illiterate or semi-illiterate. The osteoporosis risk test questions showed that smoking, heavy drinking, and erectile dysfunction and reduced sexual desire were the main sources of osteoporosis risk in men. Menopause before the age of 60, ≤45 years old, no milk and no calcium supplements, parents with osteoporosis or bone fractures were the major risk sources of osteoporosis in women. Conclusion The risk of osteoporosis among male residents from 30 to 65 years old in typical hot spring areas in Guizhou province is higher than that among women. Education of osteoporosis prevention should be strengthened among local residents to promote healthy behaviors and lifestyles.

ABSTRACT

Objective To investigate the prevalence of osteoarthrosis and the association between hot spring bathing and osteoarthrosis among local adults in typical hot spring areas of Guizhou Province. Methods A face-to-face questionnaire survey was conducted among residents aged from 30 to 65 in five typical hot spring areas, including Xifeng(Xifeng County, Guiyang), Jianhe(Jianhe County, Qiandongnan), Fodingshan(Shiqian County, Tongren), Guiyu(Wudang District, Guiyang)and Huishangu(Suiyang County, Zunyi). Residents' basic information, bone and joint diseases prevalence, hot spring bathing, and other health-related behaviors were investigated in this study. The prevalence of local bone and joint diseases was analyzed, and binary logistic regression was used to calculate OR(95%CI)to analyze the association between hot spring bathing and bone and joint diseases. Results A total of 3 708 adults(1 648 males and 2 060 females)were included as the statistical analysis survey subjects, and 794 people reported bone and joint diseases, accounting for a prevalence rate of 21.41%, 95% CI: 0.201-0.227. The prevalence of females(24.56%)was higher than that of males(17.48%)(P < 0.001). The prevalence rates of diseases increased with age(χtrend2=130.265, P < 0.001). There were also statistically significant differences in the prevalence rate of bone and joint diseases among different genders, age groups, occupations, education levels, and smoking behaviors(P < 0.05). After gender, age, occupation, education and smoking were adjusted for, compared with the group who never took hot spring baths, participants who took hot spring baths occasionally(OR=0.793, 95%CI: 0.631-0.996)and frequently(OR=0.713, 95%CI: 0.536-0.948)were associated with a lower risk of bone and joint diseases. Conclusion The prevalence of osteoarthrosis is 21.41% in the typical hot spring areas of Guizhou Province. Older or females have a higher risk of prevalence of bone and joint diseases. Hot spring bathing may be associated with a lower risk of bone and joint diseases.

ABSTRACT

Objective To investigate the association between hot spring bathing behavior and hypertension and understand the mediation effect of sleep quality problems on the association. Methods A cross-sectional survey was conducted among adults aged 30 to 65 living and working around five hot springs in Guizhou Province, employing a self-designed questionnaire on the health status and hot spring bathing, and 3 708 qualified questionnaires were collected. Participants were divided into three groups according to their frequency of hot spring bathing: never, occasionally, and frequently. Stratified via sex and sleep quality, the binary logistic regression model was used to analyze the association between different hot spring bathing frequencies and self-reported hypertension. Results Significant difference was detected in the self-reported hypertension between groups who never bathe(13.7%), who occasional bathe(9.4%)and who frequently bathe(8.5%)among female participants(χ2=10.460, P=0.005). However, no significant difference was found among different bathing groups in males. Furthermore, multivariate analysis showed that compared with no bathing, occasional(OR=0.692)and frequent (OR=0.594)hot spring bathing were associated with lower hypertension prevalence among female population, and female groups of occasional and frequent bathing with sleep quality problems had smaller OR(OR=0.571 and 0.406, respectively). After sleep quality problems were included, hot spring bathing was still associated with lower hypertension risk, and the OR values of occasional bathing and frequent bathing groups were 0.723 and 0.611, respectively. The sleep quality problems of female population played a partial mediating role in the association between hot spring bathing and hypertension, and the relative mediating effects of occasional bathing and frequent bathing with hypertension were both statistically significant(Zm=-2.022 and -1.995, P < 0.05), which accounted for 34.34% and 30.15% of the total effects, respectively. Conclusion Regular hot spring bathing may play an auxiliary role in the prevention of hypertension, and it may provide a stronger protection for women, and especially those with sleep quality problems. Sleep quality problems may explain part of the association between hot spring bathing and hypertension in female population.

ABSTRACT

Objective To analyze the association between hot spring bathing and the quality of life of smokers living in typical hot spring areas of Guizhou to make suggestions on improving their quality of life. Methods The study is a cross-sectional study whose data was collected by questionnaires. The WHO Quality of Life Scale(WHO QOL-BREEF)was used to measure quality of life. Results The quality of life in the psychological domain(14.09±1.83 vs 13.79±1.82, P < 0.05)and the environmental domain(12.70±1.84 vs 12.37±1.67, P < 0.05)among smokers who took hot spring baths was significantly higher than that among those who did not. After adopting ordinary logistic regression model to adjust for other factors, for the physical domain, the odd of scoring"good"in the WHO scale in group of smokers who took hot spring baths less that once a month was 0.70 lower than that in those who took baths at least once a month(OR=0.70, 95%CI: 0.54-0.91). In psychological domain, the odd of the group of smokers who did not take hot spring baths was 0.65 lower than that in those who took baths at least once a month(OR=0.65, 95%CI: 0.47-0.90). And the odd of the group of smokers who bathed less than once in a month was 0.71 lower than those who bathed at least once a month(OR=0.71, 95%CI: 0.54-0.92). Conclusion There is a positive relationship between hot spring bathing and quality of life, which prompts that people who smoke take hot spring baths to improve their quality of life.

ABSTRACT

Objective To investigate hot spring bathing behavior and chronic disease prevalence of residents aged 30 to 65 in typical hot spring areas of Guizhou Province. Methods Totally 3 708 individuals between 30 and 65 in five typical hot spring areas of Guizhou Province were included in this study. Their hot spring bathing behavior and chronic disease prevalence were recorded. Unconditional logistic regression was used to analyze the association between hot spring bathing and the incidence of chronic diseases. Results 71.3% of the residents in the hot spring areas had bathed in hot springs, with the proportion higher in males than females(χ2=92.856, P < 0.001). 76.3% of people took hot spring baths fewer than or equal to 6 times per year, 30.8% of residents often chose to take hot spring baths in the evening, and 37.6% of the residents took hot spring baths for 21-40 minutes. Bathing was more common in winter. 11.5% and 17.9% of the residents added other substances and used hot spring facilities, and most of them added traditional Chinese medicine and used the sauna. 46.6% and 41.6 % of the residents took hot spring baths to relax and relieve fatigue. The self-reported prevalence rate of chronic diseases was 522.1‰, and the top five single diseases were lumbar intervertebral disc disease(119.7‰), hypertension(118.1‰), urinary calculus(77.7‰), cervical intervertebral disc disease(53.7‰)and osteogenesis(44.5‰). Compared with those who never bathed in hot springs, taking hot spring baths 7-11 times a year was negatively correlated with chronic diseases.(OR=0.551, 95%CI: 0.345-0.879). Conclusion Hot spring bathing is popular in typical hot spring areas of Guizhou Province, but its frequency is not high. The overall prevalence of chronic diseases is relatively high, and the order of most prevalent chronic diseases is different from that in other areas. Proper hot spring bathing is negatively correlated with chronic diseases.

ABSTRACT

Objective:To investigate the effect of acteoside on the expressions of high mobility group box 1 (HMGB1) and nuclear factor-κB (NF-κB) in the renal tissue of diabetic nephropathy mice.Methods:Among 20 healthy 8-week old C57BL/6J mice, 5 mice were randomly selected as normal control group, the rest were established as type 1 diabetes mellitus (T1DM) models by a single intraperitoneal injection of streptozocin (STZ, 150 mg/kg). T1DM mice were randomly divided into three groups: 5 mice without treatment, 5 mice treated with acteoside and 5 mice treated with irbesartan. After continuous administration for 8 weeks, serum, urine, and kidney tissue were collected for biochemical, pathological, and related mRNA and protein detection. The renal tubular epithelial cells (NRK-52E cells) were divided into control group (1 g/L glucose), high glucose group (4.5 g/L glucose) and high glucose+acteoside group (4.5 g/L glucose+32 μmol/L acteoside). Real-time PCR and Western blotting were used to assess the expressions of HMGB1 and NF-κB after 48 hours and 72 hours culturing.Results:Compared with normal control group, blood glucose, 24-hour quantitative urinary protein, blood urea nitrogen (BUN), serum creatinine (Scr) and blood and urine HMGB1 were significantly increased in model group (all P<0.05), along with interstitial inflammatory cell infiltration and messangial matrix expantion, and the expressions of HMGB1 and NF-κB were significantly enhanced (all P<0.05). Compared with model group, histopathologic changes were alleviated and the mRNA and protein expression levels of HMGB1 and NF-κB were lower in the acteoside group (all P<0.05), while the blood glucose level was maintained at high level ( P>0.05), excluding reduced quantitative 24-hour urinary protein, BUN, Scr, and serum and urine HMGB1 (all P<0.05). Compared with control group, the mRNA and protein expressions of HMGB1 and NF-κB were increased in high glucose group of NRK-52E cells (all P<0.05). Compared with high glucose group, the mRNA and protein expressions of HMGB1 and NF-κB in high glucose+acteoside group were down-regulated (all P<0.05). Conclusion:Acteoside may alleviate the nephropathy in STZ-induced diabetic nephropathy mice by down-regulating the expressions of HMGB1 and NF-κB.

ABSTRACT

Objective:To investigate the status of frailty and activities of daily living (ADL) in maintenance hemodialysis (MHD) patients, and to explore the effect of frailty phenotype on ADL.Methods:The patients who underwent MHD in Kidney Disease Center of the First Affiliated Hospital from March 2019 to March 2020 were enrolled in this study. The demographic and laboratorial data were collected by cross-sectional survey method. Fried frailty phenotype scale and ADL scale were used to evaluate the frailty and ADL, respectively. The differences of basic data and different frailty phenotypes between the normal function group and the function decline group were compared in terms of ADL, physical self-maintenance ability and instrumental ADL ability. Pearson correlation analysis was used to analyze the correlation between frailty and ADL, and binary logistic regression analysis was used to analyze the influencing factors of ADL.Results:A total of 676 MHD patients were included in this study, including 434 males (64.2%) and 242 females (35.8%). The age was (59.2±19.4) years old, and the median dialysis age was 59.0 (25.3, 110.0) months. There were 159 frailty patients (23.5%), 230 pre-frailty patients (34.0%), and 287 non-frailty patients (42.5%). The ADL was decreased in 163 patients (24.1%), including 131 patients (19.4%) with decreased physical self-maintenance ability and 161 patients (23.8%) with decreased instrumental ADL ability. Pearson correlation analysis showed that the frailty score was positively correlated with total ADL score ( r=0.728, P<0.001), physical self-maintenance ability score ( r=0.669, P<0.001) and instrumental ADL ability score ( r=0.729, P<0.001). Binary logistic regression analysis results showed that older age and lower physical activity, fatigue, slowed steps and lower grip strength in the frailty phenotypes were the independent influencing factors of ADL, physical self-maintenance ability and instrumental ADL ability (all P<0.05). Conclusions:The prevalence of frailty is 23.5% in MHD patients, and 24.1% of MHD patients have decreased ADL. Elder age and lower physical activity, fatigue, reduced step counts, and lower grip strength in frailty phenotypes are the independent influencing factors for poor ADL, poor physical self-maintenance ability and poor instrumental ADL ability.

ABSTRACT

This research established the HPLC methods for the determination of perillaketone, perillaldehyde, caffeic acid, scutellarin, and rosmarinic acid in 33 batches of Perillae Folium. Kromasil C_(18)(4.6 × 250 mm, 5 μm) chromatographic column was used, and the mobile phase for determination of the perillaketone and perillaldehyde was methanol-water(55∶45) solution, at a flow rate of 1.0 mL·min~(-1), with the column temperature at 30 ℃. The mobile phase for the determination of caffeic acid, scutellarin and rosmarinic acid was methanol(A)-0.2% phosphoric acid aqueous solution(B) with gradient elution(0-20 min, 25%-30% A; 20-60 min, 30%-43% A). The flow rate was 1.0 mL·min~(-1) and the column temperature was set at 30 ℃. The results showed that the established method can achieve good separation of the five components in samples, with a good linear relationship and high accuracy, indicating that the methods can be used for the determination of Perillae Folium. The results showed that all samples contained five components. And the content of rosmarinic acid(0.04%-1.57%) > scutellarin(0.03%-0.77%) > perillaldehyde(0.02%-0.66%) > perillaketone(0.03%-0.30%) > caffeic acid(0.006%-0.07%). Thirty-three Batches of Perillae Folium can be grouped into 5 categories. There are certain content rules and region specificities under different clusters. Perillaketone, perillaldehyde, and rosmarinic acid can be used as the main markers to evaluate the quality of Perillae Folium.

ABSTRACT

In recent years, the establishment of the commercial grade of Yinpian [traditional Chinese medicine(TCM) pieces for decoction] in the TCM industry has been hotly disputed. In this article, Sophorae Flavescentis Radix(SFR) was selected as a representative example to investigated. Through systematic comparison and analysis, the different grades of SFR slices were traced, verified and evaluated. According to the current published local grade standards of SFR slices, the results showed that the first-class of SFR slices were mostly derived from the wild medicinal materials, the second-class were mostly originated from the cultivated materials in 3-4 years, and the third-class products were from a small number of lateral roots and short-growing years or harsh habitat of wild medicinal materials. On the basis of identifying the sources of different grades of SFR slices, the contents of the active components, including matrine, oxymatrine, oxysophocarpine, sophoridine, N-methyl-cytisine, sophocarpine, were quantitatively determined in typical samples, it was found that the grades were inversely proportional to the contents of active ingredients. In order to ensure the universality of the conclusion, the contents of different grades of commercial SFR slices were determined, and the conclusion was verified as "the commercial grades of SFR slices were inversely linked to their contents of active ingredients". This phenomenon is common in the determination of the commercial grade of Yinpian of radix and rhizome. Therefore, we propose that the method or standard of the commercial grade of Yinpian of radix and rhizome based on the size of Yinpian maybe not proper. Whether and how to classify Yinpian commercial grade is not only a multi-disciplinary issue, especially in combination with clinical efficacy, but also a big problem need to consider the production, commercial circulation and other processes link of quality risk and quality assurance, and should be treated with great caution.

ABSTRACT

As anti-aging ingredients, β-nicotinamide mononucleotide(NMN) and nicotinamide adenine dinucleotide(NAD~+) have attracted worldwide attention in recent years. After oral administration, NMN can be converted into NAD~+ in vivo and the latter is the actual ingredient which exerts anti-aging effect. In order to explore the "rejuvenating and anti-aging" effect of Dendrobium officinale, which was firstly recorded in Shennong's Herbal Classic of Materia Medica, this study established the quantitative method of UPLC-MS/MS for simultaneous determination of NMN and NAD~+ in D. officinale and the congeneric species for the first time, and 34 batches of samples were detected. UPLC conditions are as follows: ACQUITY UPLC HSS T3 column(2.1 mm × 100 mm, 1.8 μm), gradient elution with acetonitrile-0.1% formic acid in water at the flow rate of 0.3 mL·min~(-1), and column temperature of 40 ℃. MS conditions were scanned electrospray ionization source and multiple reaction monitoring mode. The method was verified by systematic methodology. The mean recoveries of NMN and NAD~+ were 77.58% and 80.70%, respectively, with RSD of 3.6% and 4.3%, separately. All results showed that the content of NMN was higher in D. officinale than in the other congeneric species. Particularly, the content in fresh D. officinale stems was as high as 0.931 9 μg·g~(-1). NAD~+ was only found in D. officinale and the content was three times higher than that of NMN. This may be the reason that D. officinale topped the "nine famous anti-aging herbs". In addition, processing method influences the content of NMN and NAD~+ in Dendrobium. Specifically, the content of NMN and NAD~+ was in the order of fresh Dendrobium stems > dried Dendrobium stem segments > spiral or spring-like dried Dendrobium stems.
