Background Health literacy is closely related to mental health, and improving health literacy has been shown to promote mental well-being. However, whether occupational stress among workers in mining and manufacturing is associated with their occupational health literacy remains inconclusive. Objective To study the levels of occupational health literacy and occupational stress among workers in three industrial sectors (metal ores mining, metal smelting, and manufacture of non-metallic mineral products) in Gansu Province, and to analyze the correlation between them. Methods Between May and December 2024, a stratified cluster random sampling method was employed to survey workers from 73 large, medium, and small and micro sized enterprises across the aforementioned industries in Gansu Province. Participants’ occupational health literacy and occupational stress levels were assessed. The LASSO regression model was applied to identifykey factors influencing occupational stress, and subsequently a multilevel random intercept mixed-effects logistic model was used to study factors influencing occupational stress and to explore the relationship between occupational health literacy and occupational stress. Results A total of 3611 workers across the three industries were surveyed, among whom 1031 (28.55%) experienced occupational stress. Workers with adequate occupational health literacy—whether assessed in terms of overall literacy or specific dimensions—demonstrated a significantly lower prevalence of occupational stress compared to those without adequate literacy (P<0.05). Through the LASSO regression analysis, it was found that the factors closely related to occupational stress were dimension one (occupational health legal knowledge), dimension two (basic knowledge of occupational health protection), and dimension four (healthy working methods and behaviors) of occupational health literacy, gender, average monthly income, and night shifts. The results from the three-level random intercept mixed-effects logistic regression model indicated that dimensions one (OR=0.69, 95%CI: 0.58, 0.82), two (OR=0.71, 95%CI: 0.58, 0.87), and four (OR=0.81, 95%CI: 0.67, 0.98) of occupational health literacy were negatively correlated with the risk of occupational stress. Workers with an average monthly income of 3001–≤5000, 5001–≤7000, and ≥7001 yuan reported occupational stress risks that were 61% (OR=0.61, 95%CI: 0.45, 0.81), 56% (OR=0.56, 95%CI: 0.41, 0.78), and 36% (OR=0.36, 95%CI: 0.24, 0.53) of those with an average monthly income ≤3000 yuan, respectively. Male workers (OR=1.66, 95%CI: 1.32, 2.10) and those on night shifts (OR=2.29, 95%CI: 1.90, 2.76) had a higher risk of occupational stress. The random effects variance showed that the intraclass correlation coefficient was 0.12. Conclusion There is a negative correlation between occupational stress and occupational health literacy among workers in mining and manufacturing. Being male, having a low income, and working night shifts are risk factors affecting workers' occupational stress. It is recommended to focus on these groups of workers and incorporate occupational health literacy into workplace mental health promotion.

Objective To analyze the epidemiological characteristics of newly diagnosed occupational coal workers' pneumoconiosis (CWP) in Gansu Province. Methods All newly diagnosed cases of CWP reported online in Gansu Province from 2005 to 2024 were collected as study subjects through the "Occupational Diseases and Health Hazard Factors Monitoring Information System". A descriptive epidemiological method was used to analyze the epidemiological characteristics. A total of 886 newly diagnosed CWP cases were reported in Gansu Province during 2005-2024. Results Among them, cases initially diagnosed as stageⅠ, stage Ⅱ, and stage Ⅲ accounted for 68.8%, 20.0%, and 11.2%, respectively. The cases were predominantly male, accounting for 99.0%. Age groups of 50-<60 years and ≥60 years accounted for 47.0% and 42.9%, respectively. In terms of regional distribution, Lanzhou City, Pingliang City, and Baiyin City were the main affected areas, accounting for 36.0%, 19.1%, and 16.4%, respectively. Regarding industry distribution, the coal mining and washing industry accounted for 91.3% of the cases. Enterprises of large and small sizes accounted for 46.0% and 29.7%, respectively. In terms of enterprise economic types, state-owned enterprises and private enterprises accounted for 54.2% and 21.6%, respectively. The median duration of dust exposure among newly diagnosed CWP cases was 18 years. As of 2024, 102 cases had progressed to a more advanced stage; among the progressed cases, stageⅠ, stage Ⅱ, and stage Ⅲ cases accounted for 58.1%, 28.3%, and 13.6%, respectively. Conclusion Cases of CWP in Gansu Province are mainly distributed in large state-owned coal mines in cities such as Lanzhou, Pingliang, and Baiyin, predominantly affecting older males with longer dust exposure durations. Therefore, occupational health supervision and management in coal dust-related enterprises in the province should be further strengthened, and the occupational health examination procedures for workers exposed to dust should be standardized.

BACKGROUND:Obesity negatively affects dynamic balance during walking,and crossing barriers is a more routine functional activity that requires more stability in controlling body posture. OBJECTIVE:To investigate the differences in dynamic stability between obese and average males,and to assess the balance ability of obese males using a relatively more challenging obstacle crossing. METHODS:A total of 24 male youths(12 each in the obese and normal groups)were recruited to complete the tests of walking on level ground and crossing obstacles of different heights(4 cm,11 cm,15 cm)in random order.Kinematic and dynamic data were collected using the Qualisys motion capture system and Kistler force stage.Statistical analysis was performed using two-factor(2 groups * 4 movement types)repeated measures analysis of variance. RESULTS AND CONCLUSION:The obese group had a lower step speed than the normal group(P<0.05),the proportion of the first single support period decreased and the proportion of the second double support period increased when crossing the 11 cm versus 15 cm hurdles(P<0.05).When walking on level ground,the margin of stability in the internal and external directions in the normal group was greater than that of the obese group(P<0.05).When crossing the 4 cm hurdles,the margin of stability in the obese group was less than that in the normal group(P<0.05).When crossing the 11 cm hurdles,there was no significant difference between the two groups in the anterior-posterior direction(P>0.05),while there was a significant difference in the internal-external direction(P<0.05).When crossing the 15 cm hurdles,the margin of stability in the obese group was lower than that in the normal group(P<0.05).Overall,obesity decreases the body's ability to control the body,reduces dynamic stability during crossing the barrier,and increases the risk of falls compared with the general population.In addition,compared with level ground walking,the decrease in the dynamic stability when crossing barriers is more significant in the obese group than the general population.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Qingfeitang， specialized in resolving phlegm to stop cough and producing fluid to moisten dryness， is a classic prescription inherited and developed by physicians of successive generations and has been included in the Catalogue of Ancient Classic Prescriptions （First Batch） published by the National Administration of Traditional Chinese Medicine （TCM） in 2018. Relevant ancient books data and modern literature were collected by bibliometrics to analyze the historic origin， formula composition， herb origin， preparation methods， processing methods， clinical effect， and indications of Qingfeitang. The key information of Qingfeitang was summarized to provide reference for the clinical application of the decoction. In this study， a total of 43 pieces of effective data on relevant ancient literature， including 35 ancient TCM books， were collected based on a systematic collation of relevant historic and modern literature. Results showed that "Qingfeitang" was originated from the "Renshen Qingfeitang" recorded in the Taiping Holy Prescriptions for Universal Relief from the Qing dynasty. The name of "Qinfeitang" was first recorded in the Yeshi Luyanfang written by YE Dalian in the Song dynasty. We suggested the modern dosage and usage of Qingfeitang as follows： "Scutellariae Radix of 5.60 g， Platycodon grandiflora， Poria， Tangerine， Fritillaria， and Cortex Mori of 3.73 g respectively， Angelicae Sinensis Radix， Asparagi Radix， Gardeniae Fructus， Armeniacae Semen Amarum， and Ophiopogonis Radix of 2.61 g respectively， Schisandra of 1 g， and Glycyrrhizae Radix et Rhizoma of 1.12 g， and they were taken 3 times daily. The above formula is recommended to be decocted with 400 mL of water， with 3.37 g ginger and 6 g jujubae fructus， to 320 mL， and taken after a meal， three times per day". Qingfeitang has the effect of resolving phlegm to stop cough and producing fluid to moisten dryness， specialized in treating cough， asthma， rash， and other symptoms in ancient times. Modern applications are mainly focused on the respiratory system， used for treating diseases such as bronchopneumonia and cough. The above research results provide a reference basis for the later development and research of Qingfeitang.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

Objective:To explore the feasibility and effectiveness of full free-breathing cardiac magnetic resonance (CMR) in clinical practice.Methods:The study prospectively included patients who underwent full free-breathing CMR and traditional breath-holding cine imaging between June 1 and June 30, 2024. An analysis and comparison were conducted on the image acquisition time, image quality, and left ventricular function parameters under two scanning methods, including left ventricular ejection fraction (LVEF), left ventricular cardiac output (LVCO),left ventricular end diastolic volume (LVEDV), left ventricular end diastolic volume index (LVEDVI), left ventricular end systolic volume (LVESV), left ventricular end systolic volume index (LVESVI), left ventricular stroke volume (LVSV), and left ventricular mass (LVM). In addition, the study conducted both quantitative and qualitative analyses of other sequences in full free-breathing CMR, including T 1 mapping, T 2 mapping, flow imaging, and late gadolinium enhancement (LGE). Group comparisons were performed using the Wilcoxon signed-rank test or paired t-test. Consistency assessments included Bland-Altman analysis, intraclass correlation coefficient ( ICC), and linear regression analysis. Results:Totally, 150 patients were recruited into the study. The average acquisition time of full free-breathing CMR was (22.1±3.1) min, with an average short axis cine sequence examination time of (2.7±0.4) min; The average acquisition time of short axis images in a breath-holding state was (4.9±1.4) min, which was significantly longer than the cine scan in the free-breathing state ( P0.001). The cine and LGE images quality scores obtained from full free-breathing CMR were 4 (4, 4) points and 5 (4, 5) points, respectively, while the cine image quality score obtained in a breath-holding state was 5 (4, 5) points. Compared with traditional breath-hold CMR, free-breathing CMR measurements showed slightly higher LVESV, and LVESVI, while LVEDV, LVEDVI, LVSV, LVCO, LVEF, and LVM were slightly lower, except for LVSV and LVCO, which showed no statistically significant difference, the differences in other cardiac function parameters were statistically significant ( P0.05). However, the two methods demonstrated good consistency( ICC0.947) and correlation (0.808 r0.993, P0.001). The Bland-Altman analysis showed that the bias for all cardiac function parameters was within 8.0%. The Native T 1 and T 2 values for free-breathing CMR were (1 277.5±57.0) ms and 40.1 (38.5, 41.4) ms, respectively, and the results of flow imaging and echocardiography were basically consistent. Conclusions:Free-breathing CMR is feasible and effective in clinical practice, showing a high level of consistency with left ventricular functional parameters obtained from traditional breath-hold scanning. It significantly shortens examination time and holds great clinical value for the promotion and widespread use of CMR.

Objective:To observe the changes of growth parameters and glucose and lipid metabolism indexes in GHD children treated with rhGH for 2 years, and analyze the influence of sex and age on these indexes.Methods:Clinical data of children with 80 cases GHD admitted to the Endocrine and Nutrition Clinic of the Beijing Children's Hospital affiliated to the Capital Medical University from July 2016 to December 2022 were analyzed retrospectively. All patients were treated with rhGH. The growth parameters, growth factors, glucose metabolism and lipid metabolism indexes were collected and calculated before treatment and at 3, 6, 12, 18 and 24 months after treatment, the influence of sex and age on these indexes and the correlations between these indicators and height growth rate were analyzed. Independent-sample t-test was used to compare two groups with normal distribution, one-way ANOVA was used to compare multiple groups, and repeated measures ANOVA was used to compare the mean of each time point within groups. The nonparametric rank sum test was used for the comparison of non-normal distribution measurement data. Pearson correlation analysis was used to analyze the correlation between HGV and each index.Results:A total of 80 children were enrolled, 39 boys and 41 girls. Grouped by age, there were 20 in the 3.00-5.99 age group, 41 in the 6.00-9.99 age group, and 19 in the ≥10.00 age group. All patients after 24 months of treatment had a higher height ((135.13±13.17) cm), HtSDS (-0.73 (-1.04, -0.41)), body weight (29.25 (23.13, 35.00) kg), weight standard deviation score (WtSDS) (-0.44 (-1.03, 0.03)), and body mass index (BMI) (15.99 (14.90,16.92) kg/m 2) compared to before treatment ((115.44±12.87) cm, -2.11 (-2.57, -2.03), 20.00 (16.00,25.00) kg, -1.48 (-2.12, -0.89) and 15.30 (14.45, 16.21) kg/m 2) all increased, and the differences were statistically significant (all P<0.05). The increase in HtSDS in the group aged 3.00-5.99 (1.74±0.29) was higher than that in the group aged 6.00-9.99 (1.57±0.33) and ≥10.00 (1.39±0.45), and the difference was statistically significant ( F=4.84, P=0.010). All patients showed an increase in insulin-like growth factor 1 (IGF-1) (329.50 (268.00, 417.25) μg/L) and insulin-like growth factor binding globulin 3 (IGFBP-3) (6.27 (5.50,6.95) mg/L) after 24 months of treatment compared to before treatment (131.50 (96.48,177.25) μg/L, 4.07 (3.60,4.88) mg/L), with statistical significance (all P<0.05). After treatment for 3 months, 6 months, 12 months, 18 months, and 24 months, children aged ≥ 10.00 years old with IGF-1 (353.00 (221.00, 493.00), (414.84±147.91), 441.00 (287.00, 578.00), (421.68±138.30), 376.00 (290.00, 581.00) μg/L) were higher than these in 3.00-5.99 years old group (181.00 (151.25, 237.75), (216.30±68.48), 239.50 (216.75, 325.00), (284.30±89.12), 293.00 (245.25, 343.75)) μg/L and 6.00-9.99 age group (253.00 (193.50, 345.50), (294.59±90.37), 284.00 (217.50, 377.50), (325.76±90.04), 345.00 (265.00, 431.00) μg/L, the difference was statistically significant (all P<0.05). At 3 months, 6 months, 12 months, and 18 months of treatment, IGFBP-3 levels were observed in children aged ≥ 10.00 years old (6.15 (5.52, 6.46), (6.56±1.26), (6.78±1.33), (6.78±1.38) mg/L) higher than 3.00-5.99 years old group (4.69 (4.43,5.11), (5.18±0.63), (5.61±0.84), (6.08±1.00) mg/L) and 6.00-9.99 age group (5.51 (4.76, 6.35), (5.61±0.81), (5.72±0.78), (6.03±0.80) mg/L, the difference was statistically significant (all P<0.05). All children with HbA1C (5.40 (5.20, 5.58)%), fasting blood glucose (5.06 (4.76, 5.24) mmol/L), triglycerides (0.67 (0.53, 1.02) mmol/L), TyG index (2.24±0.48), and triglyceride/HDL-C ratio (1.05 (0.73, 1.50)) after 24 months of treatment compared to before treatment (5.10 (5.00, 5.28)%, 4.78 (4.51, 5.09) mmol/L, 0.57 (0.47, 0.72) mmol/L, (1.92±0.36), 0.86 (0.65, 1.08). The level of cholesterol increased, and the total cholesterol (3.74 (3.39, 4.31) mmol/L) decreased compared to before treatment (3.95(3.64, 4.54) mmol/L), with statistical significance (all P<0.05). Female patients had higher levels of triglycerides (0.79 (0.59, 1.09) mmol/L) and TyG index (2.31±0.49) than male patients (0.66 (0.53,0.89) mmol/L, (2.16±0.46)) after 18 months of treatment. The triglyceride/HDL-C at 12 months (1.10(0.67, 1.93)), 18 months (1.16(0.83, 1.68)), and 24 months (1.26 (0.79, 1.81)) of treatment ratio was also higher than male patients (0.76 (0.61, 1.09), 0.90 (0.72, 1.08), 0.98 (0.66, 1.30)). Female HDL-C levels at 18 months (1.52 (1.29,1.75) mmol/L) and 24 months (1.45(1.29,1.76) mmol/L) of treatment were significantly lower in males (1.72 (1.45, 1.84), 1.59 (1.43, 1.92) mmol/L) with statistical significance (all P<0.05). HGV was positively correlated with IGF-1 at 12 months ( r=0.243, P=0.030) , 18 months ( r=0.277, P=0.013) and 24 months ( r=0.289, P=0.009), and it was positively correlated with IGFBP-3 at 18 months ( r=0.242, P=0.030) and 24 months ( r=0.236, P=0.035), but it was negatively correlated with HDL-C at 18 months ( r=-0.331, P=0.003) and 24 months ( r=-0.281, P=0.012). Conclusions:RhGH can obviously improve HtSDS and WtSDS in GHD children. Growth factors, glucose metabolism and lipid metabolism should be monitored during the treatment. Especially for female patients (≥10.00 years old), we should closely monitor the indexes of glucose and lipid metabolism in order to avoid metabolic diseases.

Objective:To investigate the affection of high mobility group nucleosome-binding protein 5(HMGN5) gene in the hepatocellular cancer tissue and HepG2 cell and its function in the growth of HepG2 cell.Methods:70 Patients with hepatocellular carcinoma who under-went surgical resection and were confirmed by postoperative pathology in Sunshine Union Hospital of Weifang City from January 2017 to June 2020 were selected. Their clinical and pathological data, surgical resection of liver cancer tissue and adjacent normal liver tissue were collected, their survival time were also recorded. The contents of HMGN5 protein in the hepatocellular cancer tissues and adjacent normal liver tissues of 70 patients were detected by immunohistochemistry. Compare the expression of HMGN5 protein in liver cancer tissue and normal liver tissue and the positive expression rate of HMGN5 protein in liver cancer tissues of hepatocellular carcinoma patients with different clinical characteristics, to analyze the relationship between HMGN5 expression and prognosis of patients with hepatocellular carcinoma.The mRNA contents of HMGN5 gene in HepG2 cells and HL-7702 cells were determined by quantitative real time polymerase chain reaction(qRT-PCR) method. After transfectHepG2 cells with HMGN5 shRNA, the proliferation ability of HepG2 cells were evaluated by cell proliferation assay and the cell apoptosis was analyzed by flow cytometry. Measurement data with normal distribution were expressed as ±s, two independent samples t test was used for comparison between groups. Counting data was expressed as n(%), χ2 test was used for comparison between groups. Survival analysis of patients was performed by Kaplan-Meier method. Results:Immunohistochemical tests showed that HMGN5 staining is strong in liver cancer tissue, but weak in normal liver tissue. HMGN5 protein expression was positive in 48 of 70 patients with hepatocellular carcinoma. The positive expression rate of HMGN5 protein in hepatocellular carcinoma tissues of patients with pathological grade 3+4 and clinical stage Ⅲ+Ⅳ was higher than that of patients with grade 1+2 and stage Ⅰ+Ⅱ, respectively. There was no significant difference in cumulative survival rate between HMGN5 positive expression group and HMGN5 negative expression group ( χ2=3.81, P=0.051). The results of qRT-PCR showed that the expression level of HMGN5 mRNA in hepatoma HepG2 cells was higher than that in normal liver HL-7702 cells [(4.51±0.45) vs (1.35±0.27), the difference was statistically significant ( t=10.43, P=<0.001). After 24, 48 and 72h of the HMGN5 gene was knockout, the survival rate of HepG2 hepatoma cells was lower than that of HL-7702 hepatoma cells (all P<0.05) and the apoptosis rate of hepatoma HepG2 cells was higher than that of liver HL-7702 cells [(18.63±1.76)%vs(1.81±0.21)%] ,the difference was statistically significant ( t=16.44, P<0.001). Conclusions:HMGN5 genes and proteins are highly expressed in the hepatocellular cancer tissues and HepG2 cells. HMGN5 gene plays an important role in the growth of hepatocellular cancer and can be used as a potential target of treatment for hepatocellular cancer.

Objective To investigate the effects of indirect moxibustion on the expressions of DNA methyltransferases(DNMT)and methylation of the brain-derived neurotrophic factor(BDNF)promoter region in uterine tissues of rats with primary dysmenorrhea(PD);To explore the mechanism of epigenetic regulation of indirect moxibustion on PD model rats.Methods A total of 32 female SD rats were randomly divided into blank group,model group,indirect moxibustion group and Western medicine group,with 8 rats in each group.The PD model with cold dampness stagnation syndrome was established using ice-water baths combined with estradiol benzoate and oxytocin.Starting from the first day of modeling,the indirect moxibustion group received salt-partitioned moxibustion at"Shenque"and ginger-partitioned moxibustion at"Guanyuan"for 20 min,while the Western medicine group was gavaged ibuprofen solution.Both interventions were given once a day for 10 days.On day 11,writhing responses were observed and scored after oxytocin injection,Western blot and RT-qPCR were used to detect protein and mRNA expression of BDNF,DNMT3A and DNMT3B in uterine tissue,immunohistochemical staining was used to detect the positive expressions of DNMT3A and DNMT3B in uterine tissue.The DNA methylation of BDNF promoter region in uterine tissue was detected by sulfite sequencing.Results Compared with the blank group,the writhing latency was shortened and the writhing score increased in the model group(P<0.01);the protein and mRNA expressions of BDNF,DNMT3A and DNMT3B in uterine tissue increased(P<0.01),the positive expressions of DNMT3A and DNMT3B increased(P<0.01),and the DNA methylation rate in BDNF promoter region decreased(P<0.01).Compared with the model group,the writhing latency was lengthened and the writhing score decreased in the indirect moxibustion group and Western medicine group(P<0.05,P<0.01);the protein and mRNA expressions of BDNF,DNMT3A and DNMT3B in uterine tissue decreased(P<0.05,P<0.01),the positive expressions of DNMT3A and DNMT3B decreased(P<0.01),and the DNA methylation rate in BDNF promoter region increased(P<0.01).Conclusion Indirect moxibustion at"Shenque"and"Guanyuan"may inhibit the transcription of BDNF by increasing the DNA methylation level of BDNF promoter region,and reduce the expression of BDNF,so as to relieve the pain of PD rats.
