Effect of Ilex hainanensis Merr. On HFD-induced nonalcoholic fatty liver disease and rebalance of gut microbiota and bile acids metabolism in mice

Nonalcoholic fatty liver disease (NAFLD) is a clinicopathological syndrome characterized by excessive intracellular fat deposition in the hepatocytes, and the development is exacerbated by gut microbiota and bile acids metabolism disorders. Ilex hainanensis Merr. is a traditional medicine of the Zhuang nationality, historically esteemed for its efficacy in lowering blood pressure and lipid levels. This study aimed to investigate the pharmacodynamic effects in NAFLD mice and impacts on gut microbiota and bile acids (BAs) metabolism of I. hainanensis extract (IHA). 16 compounds were identified from IHA by HPLC-DAD-MS analysis. IHA significantly reduced body weight indexs, alanine transaminase (ALT) and aspartate transaminase (AST) activities, improved dyslipidemia and insulin resistance (IR), and effectively ameliorated hepatic steatosis in HFD-induced NAFLD mice. IHA also altered gut microbiota composition, particularly enhancing the abundance of bacteria involved in BAs metabolism, as well as augmented BAs synthesis in the liver and increased fecal excretion. In conclusion, our findings suggest that IHA holds promise in improving NAFLD conditions and modulating gut microbiota and BAs metabolism. These insights contribute to a deeper understanding of the mechanisms underlying IHA-mediated alleviation of lipid accumulation in NAFLD.

A novel antidepressant homogeneous polysaccharide YLP-1 from Millettia pulchra ameliorates tryptophan metabolism and SCFAs through modulating gut microbiota

The root of Millettia pulchra (YLS) has been traditionally used as a folk medicine for the treatment of depression and insomnia in the Zhuang nationality of China, and its polysaccharides have potential antidepressant effect. In this study, a novel homogeneous polysaccharide (YLP-1) was purified from the crude polysaccharides of YLS, and it is mainly composed of glucose, arabinose and mannose with molar ratio of 87.25%, 10.77%, and 1.98%, respectively. YLP-1 is a novel α-glucan with the backbone of 1,4-Glcp and branched at C6 of 1,4,6-Glcp to combine 1,4-Manp and 1,5-Araf. The microstructure of YLP-1 displayed a uniform ellipsoidal-like chain morphology and dispersed uniformly in solution. YLP-1 effectively ameliorated depression-like ethological behaviors and restored the decreased catecholamine levels in chronic variable stress (CVS)-induced depression rats. Additionally, it significantly improved the disturbance of gut microbiota induced by CVS stimuli, particularly affecting bacteria that produce short-chain fatty acids (SCFAs), such as bacteria species Lactobacillus spp.. In vitro fermentation study further confirmed that YLP-1 intake could promote SCFAs production by Lactobacillus spp. YLP-1 also mitigated the disruption of tryptophan metabolites in urine and serum. These findings provide evidences for the further development of YLP-1 as a macromolecular antidepressant drug.

Epidemiological characteristics and prevention of pressure injury in older inpatients of Zhuang and Han ethnicity in Guangxi, China: a cross-sectional study.

Pressure injury (PI) is a significant health concern among older inpatients, particularly in regions with diverse ethnic populations. Understanding the epidemiological characteristics and preventive measures is crucial for improving patient outcomes. To analyze the epidemiological characteristics, prevention status, and influencing factors of pressure injury (PI) in older inpatients of Zhuang and Han nationality in Guangxi, China. A total of 2206 inpatients age 60 years or older in 2 class III grade A general hospitals in the Guangxi Zhuang Autonomous Region between April 1, 2021, and May 27, 2021, were included in this cross-sectional study. Epidemiological characteristics-including age, sex, educational background, race, ethnicity, and hospitalization information-were collected using a general information questionnaire designed by the researchers. The PI risk factors were evaluated using the Braden Scale. Prevention status was assessed using the Epidemiology and Prevention Skin Injuries in the Elderly Scale and Skin Injury Survey Scale. Of the total 2206 patients included in the study, 555 (25.16%) were of Zhuang nationality and 1651 (74.84%) were of Han nationality. The overall PI incidence was 2.58%, with PI prevalence of 1.80% and 2.85% in Zhuang and Han patients, respectively. The main influencing factor for PI in Zhuang patients was caregivers (P < .05), whereas in Han patients the main influencing factors were urinary conditions, Alzheimer disease, sedatives, and antihypertensive drugs (P < .05). The PI prevalence rates were similar in both ethnic groups. Health care staff in high-risk departments for PI must remain vigilant and take appropriate action.

Exploring the Inheritance and Development of Guangxi Zhuang Brocade

The Zhuang nationality is one of the ethnic minorities with a large population in China, mainly distributed in the Guangxi Zhuang Autonomous Region. In the long river of history, the people of the Zhuang nationality have created an excellent Zhuang culture with distinctive national characteristics, including material culture and spiritual culture, by virtue of their hard work and wisdom. As one of the most representative cultural treasures of the Zhuang nationality, Zhuang brocade, together with Song brocade, Yun brocade and Shu brocade, is known as the four famous brocades in China, and it has been included in the first batch of national intangible cultural heritage in the protection list. However, in recent years, the Zhuang brocade has encountered bottlenecks in the process of inheritance and development, making it difficult for the Zhuang brocade to be known to the whole country and even more difficult for it to be known to the world. The inheritance of national culture is a major issue related to the sustainable development of the nation, which needs to be paid great attention to. This paper focuses on analyzing the development problems encountered by Zhuang brocade in modern society, and exploring the path of Zhuang brocade inheritance and development.

Integrating metabonomics and metagenomics sequencing to study the anti-liver fibrosis effects of palmatine in Corydalis saxicola Bunting

Ethnopharmacological relevanceCorydalis saxicola Bunting (CS), a traditional Chinese folk medicine, has been effectively used for treating liver disease in Zhuang nationality in South China. However, the main anti-liver fibrosis ingredients in CS are incompletely understood. Aim of the studyTo elucidate the main anti-liver fibrosis ingredients in CS and its underlying mechanism. Material and methodsFirstly, spectrum-effect relationship (SER) strategy was applied to identify the major ingredients against liver fibrosis in CS. Subsequently, 1H NMR metabonomics and metagenomics sequencing techniques were used to clarify the intervention of palmatine (PAL) on liver fibrosis. Furthermore, the expression of tight junction proteins and the levels of liver inflammation factors were examined, the effect of PAL on microbiota was verified by FMT. ResultsThe SER model revealed that PAL was the most important active ingredient in CS. 1H NMR fecal metabonomics showed that PAL could reserve the abnormal levels of gut microbial-mediated metabolites of liver fibrosis, such as isoleucine, taurine, butyrate, propionate, lactate, glucose, which mainly involved in amino acid metabolism, intestinal flora metabolism and energy metabolism. Metagenomics sequencing found that PAL could callback the abundance of s__Lactobacillus_murinus, s__Lactobacillus_reuteri, s__Lactobacillus_johnsonii, s__Lactobacillus_acidophilus and s__Faecalibaculum_rodentium to varying degree. Furthermore, the intestinal barrier function and the levels of hepatic inflammation factors were significantly ameliorated by PAL. FMT demonstrated that the therapeutic efficiency of PAL was closely associated with gut microbiota. ConclusionThe effects of CS on liver fibrosis were attributed in part to PAL by alleviating metabolic disorders and rebalancing gut microbiota. The SER strategy may be a useful method for the discovery of active constituents in natural plants.

Objective: To understand the distribution of genotypes and sub-genotypes of HBV in different ethnic groups in China. Methods: The HBsAg positive samples were selected by stratified multi-stage cluster sampling from the sample base of national HBV sero-epidemiological survey in 2020 for the amplification of S gene of HBV by nested PCR. A phylogeny tree was constructed to determine the genotypes and sub-genotypes of HBV. The distribution of genotypes and sub-genotypes of HBV were analyzed comprehensively by using laboratory data and demographic data. Results: A total of 1 539 positive samples from 15 ethnic groups were successfully amplified and analyzed, and 5 genotypes (B, C, D, I and C/D) were detected. The proportion of genotype B was higher in ethnic group of Han (74.52%, 623/836), Zhuang (49.28%, 34/69), Yi (53.19%, 25/47), Miao (94.12%, 32/34), Buyi (81.48%, 22/27). The proportions of genotype C were higher in ethnic groups of Yao (70.91%, 39/55). Genotype D was the predominant genotype in Uygur (83.78%, 31/37). Genotype C/D were detected in Tibetan (92.35%,326/353). In this study, 11 cases of genotype I were detected, 8 of which were distributed in Zhuang nationality. Except for Tibetan, sub-genotype B2 accounted for more than 80.00% in genotype B in all ethnic groups. The proportions of sub-genotype C2 were higher in 8 ethnic groups, i.e. Han, Tibetan, Yi, Uygur, Mongolian, Manchu, Hui and Miao. The proportions of sub-genotype C5 were higher in ethnic groups of Zhuang (55.56%, 15/27) and Yao (84.62%, 33/39). For genotype D, sub-genotype D3 was detected in Yi ethnic group and sub-genotype D1 was detected in both Uygur and Kazak. The proportions of sub-genotype C/D1 and C/D2 in Tibetan were 43.06% (152/353) and 49.29% (174/353). For all the 11 cases of genotype I infection, only sub-genotype I1 was detected. Conclusions: Five genotypes and 15 sub-genotypes of HBV were found in 15 ethnic groups. There were significant differences in the distribution of genotypes and sub-genotypes of HBV among different ethnic groups.

The prevalence of hyperuricemia and its correlates in Zhuang nationality, Nanning, Guangxi Province.

Hyperuricemia has an increasing incidence in various regions year by year, in this study, we evaluated the prevalence of hyperuricemia in a routine physical examination in Nanning, Guangxi Province, and analyzed the influencing factors of hyperuricemia, aiming to provide evidence for the prevention and treatment of hyperuricemia and related diseases. Data were collected from 1957 patients who underwent physical examinations at the First Affiliated Hospital of Guangxi Medical University in China since 2017. Questionnaires were structured, including subjects' demographics, lifestyle, personal history, chronic disease history, medication history, etc. UA (uricase method), TC (cholesterol oxidase method), TG (glycerol phosphate oxidase method), HDL-C (direct method), LDL-C (direct method), BUN (rate method), creatinine (sarine oxidase method), and GLU (oxidase-peroxidase method) were detected. Independent risk factors for hyperuricemia were determined by bivariate non-conditional logistic regression analysis. The overall prevalence of hyperuricemia was 16.6% (19.5% in males and 14.9% in females). Gender, waist circumference, BMI, the proportion of drinking, hypertension, high education, serum concentrations of TC, TG, LDL-C, BUN, and creatinine were significantly higher and the serum concentration of HDL-C was significantly lower in patients with and without hyperuricemia (all p < 0.05). Waist circumference, BMI, BUN, and creatinine were independent risk factors for hyperuricemia. The prevalence of hyperuricemia is very high in Guangxi. Public health lectures should be conducted to encourage people to establish a healthy lifestyle and strengthen early intervention for hyperuricemia to reduce the risk of cardio-cerebrovascular and other related diseases.

Action Mechanism of Zhuang Medicine Jin-mu Granules Against Chronic Pelvic Inflammatory Disease Explored Using Comprehensive Network Pharmacology and Metabolomics

Zhuang Medicine Jin-mu Granules (ZMJG) are prescriptions derived from the Zhuang nationality, which is the largest minority among 56 ethnic groups in China. They have been widely used in the treatment of chronic pelvic inflammatory disease (CPID) in Guangxi Zhuang Autonomous Region for clearing away heat and toxins, removing dampness and poisoning. CPID is a common gynecological disease of female reproductive organs and surrounding tissues and is characterized by persistent and recurrent symptoms, causing serious physical and psychological damage to the patient. Preliminary research found that ZMJG have beneficial effects on CPID model rats, but the metabolic mechanism underlying their protective effects is unclear. In this study, we used the strategy of combining network pharmacology, pharmacodynamic, and metabolomic approaches to investigate the molecular mechanisms and potential targets of ZMJG for the treatment of CPID. First, a network diagram of “medicinal materials-components-targets-pathways” based on network pharmacology was constructed to obtain a preliminary understanding of the biologically active compounds and related targets of ZMJG and clarify their molecular mechanism in CPID. Subsequently, the in vivo efficacy of ZMJG was verified in a rat model. Furthermore, we analyzed the corresponding metabolomics profile to explore the differentially induced metabolic markers and elucidate the metabolic mechanism by which ZMJG treat CPID. The results show that the therapeutic effect of ZMJG on CPID is mediated through multiple pathways, metabolic pathways, and multi-component multi-target modes, providing a detailed theoretical basis for the development and clinical application of ZMJG and a new research idea for the treatment of CPID in Chinese medicine.

Relationship between exposure of alkylphenols in serum of pregnant women during early pregnancy and adverse birth outcomes.

Alkylphenols are a type of endocrine disruptors, which are commonly found in personal care products, food, and water and are more harmful to the human body. To investigate the relationship between exposure of alkylphenols in serum of pregnant women during early pregnancy and adverse birth outcomes, a total of 2035 healthy pregnant women and their neonates were recruited in the birth cohort of Zhuang nationality in Guangxi from 2015 to 2018. The peripheral venous blood samples were collected from pregnant women in early pregnancy; the concentrations of nonylphenol (NP), 4-nonylphenol (4-N-NP), 4-tert-octylphenol (4-T-OP), and 4-n-octylphenol (4-N-OP) in serum were detected by ultra-performance liquidperformance chromatography-tandemmass spectrometry (UPLC-MS). Binary logistic regression showed that NP [OR = 1.40 (95% CI: 1.00, 1.94)] was positively associated with preterm birth. Restricted cubic spline analyses showed that logNP and log4-T-OP had non-linearity associations with preterm birth (logNP: Poverall = 0.006, Pnon-linear = 0.003; log4-T-OP: Poverall = 0.004, Pnon-linear = 0.002). Multiple linear regression analysis showed that maternal serum concentration of NP was negatively associated with birth weight of perinatal infants (β = -14.68, 95% CI: -29.18, -0.19), which may be sensitive in male neonates (β = -26.18, 95% CI: -47.33, -5.02). The findings demonstrate that nonylphenol is a risk factor of preterm birth, and nonylphenol is negatively associated with the birth weight in male infants.

Prevalence, awareness, treatment and control of hypertension in Guangxi Zhuang Autonomous Region

Hypertension (HTN) is getting more prevalent in China, but the HTN's status in Guangxi remains unclear. Our study started from 2013 to 2015 and was dedicated to better acknowledging the status of HTN in Guangxi. The study enrolled 17,100 residents aged ≥ 15 years across Guangxi, from 2013 to 2015, using a stratified multistage random sampling method. Parameters including blood pressure (BP), height, and weight were measured by validated devices. HTN was defined as the average systolic BP (SBP) ≥ 140 mm Hg and/or average diastolic BP (DBP) ≥ 90 mm Hg, or any usage of antihypertensive medications within two weeks. The awareness, treatment, and control were defined as a self-reported history of HTN, a self-reported current usage of antihypertensive medications, and a BP lower than 140/90 mm Hg, respectively. The age and sex-standardized prevalence, awareness, treatment, control rates of HTN for the population aged ≥ 15 years in Guangxi were 15.80%, 16.48%, 11.99%, 3.62%, respectively. Prevalence and control rates were the same for men and women (P > 0.05), while women’s awareness and treatment rates were higher than those of men (P < 0.05). Zhuang nationality had a higher prevalence than Han (23.50% vs. 20.35%, P < 0.001), while Han had higher awareness, treatment, control rates (37.39% vs. 31.22%, 30.59% vs. 22.37%, 8.99% vs. 4.55%, individually, P < 0.05). HTN was prevalent in Guangxi, while the awareness, treatment, control rates were adverse. Region-specific strategies to intervene in HTN were needed.

Relationship between Muscle Strength, Muscle Mass and BMD in Postmenopausal Female of Zhuang in Guangxi Province of China

Objective: To explore the correlation between muscle strength, muscle mass and bone mineral density (BMD) in Zhuang female population, body composition analysis and grip strength, and to analyze the possible influencing factors of BMD. Methods: 182 postmenopausal women were selected from Guangxi Province of China. Broadband ultrasound attenuation (BUA) was used to evaluate BMD. Grip dynamometer to assess muscle strength. Height, weight and muscle mass of each part were measured by body composition measuring instrument. Body mass index (BMI), skeletal muscle mass index (SMI) and limb skeletal muscle mass (SM) were calculated according to the measurement results. Results: BUA, grip strength and SMI in postmenopausal women of Zhuang nationality showed a decreasing trend with age (p p p r = 0.305, p 2 = 0.350). Only when age was not considered, the combination of grip strength and LSM was the optimal solution to reflect the calcaneal bone density of Zhuang women (R2 = 0.306). Conclusion: With the increase of age, the decline rate of muscle strength of postmenopausal Zhuang women in Guangxi is slower than that of BMD and muscle mass. SM can better reflect the BMD level of the body than SMI, and the LSM is the main influencing factor of BMD.

The Correlation Between MYO9B Gene Polymorphism and Inflammatory Bowel Disease in the Guangxi Zhuang Population.

ObjectiveTo analyze the correlation between site rs962917 of the MYO9B gene and inflammatory bowel disease (IBD) in the Guangxi Zhuang nationality population.MethodsThe intestinal mucosa tissue of 153 IBD subjects (Han and Zhuang patients only) in the Guangxi Zhuang autonomous region comprised the case group, and the intestinal mucosa tissue of 155 healthy subjects (Han and Zhuang patients only) in the same region represented the control group. Deoxyribonucleic acid was extracted from the intestinal mucosa tissue of each experimental group, and the MYO9B gene-target fragment containing the single nucleotide polymorphism (SNP) site rs962917 was designed. Finally, polymerase chain reaction products were obtained by amplification, analyzed, and compared using the sequencing results.ResultsThe results indicated that the genotype frequency of the MYO9B SNP site rs962917 between Crohn’s disease (CD) and control groups of Zhuang and Han participants differed significantly (P < 0.05). Furthermore, the genotype frequency of MYO9B site rs962917 differed significantly between the Zhuang and Han population groups (P < 0.05).ConclusionSite rs962917 of the MYO9B gene is related to CD susceptibility and incidence among the Guangxi Zhuang population.

A network pharmacology-based approach to explore the active ingredients and molecular mechanism of Lei-gong-gen formula granule on a spontaneously hypertensive rat model

BackgroundLei-gong-gen formula granule (LFG) is a folk prescription derived from Zhuang nationality, the largest ethnic minority among 56 nationalities in China. It consists of three herbs, namely Eclipta prostrata (L.) L., Smilax glabra Roxb, and Centella asiatica (L.) Urb. It has been widely used as health protection tea for hundreds of years to prevent hypertension in Guangxi Zhuang Autonomous Region. The purpose of this study is to validate the antihypertensive effect of LFG on the spontaneously hypertensive rat (SHR) model, and to further identify the effective components and anti-hypertension mechanism of LFG.MethodsThe effects of LFG on blood pressure, body weight, and heart rate were investigated in vivo using the SHR model. The levels of NO, ANG II, and ET-1 in the serum were measured, and pathological changes in the heart were examined by H&E staining. The main active components of LFG, their corresponding targets, and hypertension associated pathways were discerned through network pharmacology analysis based on the Traditional Chinese Medicine Systems Pharmacology (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID), and the Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM). Then the predicted results were further verified by molecular biology experiments such as RT-qPCR and western blot. Additionally, the potential active compounds were predicted by molecular docking technology, and the chemical constituents of LFG were analyzed and identified by UPLC-QTOF/MS technology. Finally, an in vitro assay was performed to investigate the protective effects of potential active compounds against hydrogen peroxide (H2O2) induced oxidative damage in human umbilical vein endothelial cells (HUVEC).ResultsLFG could effectively reduce blood pressure and increase serum NO content in SHR model. Histological results showed that LFG could ameliorate pathological changes such as cardiac hypertrophy and interstitial inflammation. From network pharmacology analysis, 53 candidate active compounds of LFG were collected, which linked to 765 potential targets, and 828 hypertension associated targets were retrieved, from which 12 overlapped targets both related to candidate active compounds from LFG and hypertension were screened and used as the potential targets of LFG on antihypertensive effect. The molecular biology experiments of the 12 overlapped targets showed that LFG could upregulate the mRNA and protein expressions of NOS3 and proto-oncogene tyrosine-protein kinase SRC (SRC) in the thoracic aorta. Pathway enrichment analysis showed that the PI3K-AKT signaling pathway was closely related to the expression of NOS3 and SRC. Moreover, western blot results showed that LFG significantly increased the protein expression levels of PI3K and phosphorylated AKT in SHR model, suggesting that LFG may active the PI3K-AKT signaling pathway to decrease hypertension. Molecular docking study further supported that p-hydroxybenzoic acid, cedar acid, shikimic acid, salicylic acid, nicotinic acid, linalool, and histidine can be well binding with NOS3, SRC, PI3K, and AKT. UPLC-QTOF/MS analysis confirmed that p-hydroxybenzoic acid, shikimic acid, salicylic acid, and nicotinic acid existed in LFG. Pre-treatment of HUVEC with nicotinic acid could alleviate the effect on cell viability induced by H2O2 and increase the NO level in cell supernatants.ConclusionsLFG can reduce the blood pressure in SHR model, which might be attributed to increasing the NO level in serum for promoting vasodilation via upregulating SRC expression level and activating the PI3K-AKT-NOS3 signaling pathway. Nicotinic acid might be the potential compound for LFG antihypertensive effect.

The average age was(11.8±0.5). There were 56.78% of students lived in city and 43.22% of students lived in county town; The nationality of the sample was as follows: Zhuang nationality 90.00%, Han nationality 7.62%, other minorities(Yao nationality, Miao nationality, Yi nationality, et al)2.05%. The Logistic regression was used to explore the effect. There were 9.75% and 6.97% of the sample reported initiation of tobacco and smoking respectively. The initiation of tobacco and smoking of boys were higher than that of girls(initiation of tobacco: χ~2=57.230, P&lt;0.001; smoking: χ~2=56.013, P&lt;0.001). The multivariate Logistic analysis showed gender was statistically significant factor of initiation of tobacco(OR=0.468, 95%CI 0.377-0.582) and smoking(OR=0.422, 95% CI 0.324-0.551), and age was statistically significant factor of initiation of tobacco(OR=1.609, 95% CI 1.446-1.791) and smoking(OR=2.026, 95%CI 1.776-2.310). Bullying was statistically significant factors of smoking(OR=1.106, 95% CI 1.073-1.140). Three protective factors were associated with a lower likelihood of initiation of tobacco(individual power: OR=0.964, 95% CI 0.951-0.976; family cohesion, OR=0.946, 95% CI 0.892-0.984; family rules, OR=0.949, 95%CI 0.930-0.965) and smoking(individual power: OR=0.962, 95% CI 0.947-0.977; family cohesion, OR=0.937, 95%CI 0.885-0.992; family rules, OR=0.952, 95%CI 0.932-0.973)in the final subscale model. Bullying increased the risk of smoking, while Individual power, family cohesion and family rules were associated with a lower likelihood of initiation of tobacco and smoking in preadolescents.

From the perspective of the traditional clothes of blue clothes Zhuang nationality, the Southern Zhuang nationality and the northern one live in different areas, so different national aesthetic constructs different embroidery art characteristics. The plain Zhuang embroidery is mostly humble embroidery, and the mountain Zhuang in the northern Guangxi mountain area is mostly skillful embroidery, which are well-made, showing the classic national characteristics. In this paper, through the analysis of the traditional clothing embroidery pattern of blue clothing Zhuang, the cultural connotation and value of related clothing decoration are studied.

Clinical characteristics of H-type hypertension and its relationship with the MTHFR C677T polymorphism in a Zhuang population from Guangxi, China.

ObjectiveThis study was designed to assess the clinical presentation of patients with H‐type hypertension who were of Zhuang nationality in Guangxi, China. The relationship between the C677T polymorphism in the MTHFR gene and H‐type hypertension was also assessed.MethodsThis was a case‐control study in which 185 Zhuang nationality patients with hypertension that had been hospitalized at the Wuming Hospital of Guangxi Medical University between February 2018 and December 2018 were assessed for plasma homocysteine (Hcy) levels. These levels were used to divide patients into H‐type (>15 μmol/L) and non‐H‐type (≤15 μmol/L) hypertension groups. Patient clinical data were then analyzed, and PCR was used to analyze samples from all patients for the presence of the C677T polymorphism in the MTHFR gene. Differences between these two groups of hypertension patients were then compared using appropriate statistical methods.ResultsWe found that relative to patients in the non‐H‐type hypertension group, patients in the H‐type hypertension group exhibited significant differences in sex, age, urea nitrogen levels, creatinine levels, and uric acid levels. There were, however, no significant differences between these two groups with respect to interventricular septum thickness, left ventricular posterior wall thickness, or ejection fraction. We did not detect any association between the MTHFR gene C677T polymorphism and H‐type hypertension in Zhuang nationality individuals in Guangxi.ConclusionRisk of H‐type hypertension is not associated with the MTHFR C677T polymorphism in hypertensive individuals of Guangxi Zhuang nationality in China.

Genetic variation of pharmacogenomic VIP variants in Zhuang nationality of southern China.

Drug gene polymorphisms are strongly associated with disease. Previous studies have shown that the frequency of drug genes varies in different populations. At present, there are no reports about the polymorphism of the drug genome in the Zhuang population in southern China. This study conducted a pharmacogenomics study on the Zhuang population in southern China. Therefore, we conducted genotyping on 105 Zhuang samples, and compared the genotyping results with those of other 11 ethnic groups after statistical analysis. Our results show that, compared with the 11 populations in the HapMap data set, the differences between the CYP2E1 rs2070676 and CYP2D6 rs1065852 of the Zhuang nationality are the largest. This study fills in the blank of the drug genome information of the Zhuang nationality in southern China. The two sites of Rs2070676 (CYP2E1) and rs1065852 (CYP2D6) provide a reliable basis for the prediction of the efficacy of certain drugs. Its main purpose is to provide theoretical basis for safe drug use in the Zhuang region of southern China.
