The Huangdi Neijing proposes the " using bitter herbs to nourish or purge" theory to guide clinical prescription and formulation of herbal remedies based on the physiological characteristics and functions of the five zang viscera, along with the properties and flavors of medicinal herbs. This study explored diabetic kidney disease pathogenesis and treatment based on the " using bitter herbs to nourish or purge" theory. Kidney dryness is a key pathological factor in diabetic kidney disease, and the disharmony of kidney dryness is an essential aspect of its pathogenesis. Strengthening is the primary therapeutic principle, and kidney dryness is a persistent factor throughout the occurrence and progression of diabetic kidney disease. In the early stage, the pathogenesis involves heat-consuming qi and injuring yin, leading to kidney dryness. In the middle stage, the pathogenesis manifests as qi deficiency and blood stasis in the collaterals, resulting in turbidity owing to kidney dryness. In the late stage, the pathogenesis involves yin and yang deficiency, with kidney dryness and disharmony. This study proposes the staging-based treatment based on the " need for firmness" characteristic of the kidney. The aim is to provide new insights for clinical diagnosis and treatment in traditional Chinese medicine by rationally using pungent, bitter, and salty medicinal herbs to nourish and moisturize the kidney. This approach seeks to promote precise syndrome differentiation and personalized treatment for different stages of diabetic kidney disease, thereby enhancing clinical efficacy.

Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

Objective:To understand the current status of personal protection in occupational population at high risk for brucellosis in China and provide evidence for the evaluation of implementation of National Brucellosis Prevention and Control Plan (2016-2020).Methods:Four counties in Shanxi Province and Xinjiang Uygur Autonomous Region were selected to conduct a questionnaire survey in occupational population at high risk for brucellosis from December 2019 to July 2020 by using cross-sectional survey methods.Results:A total of 2 384 persons at high risk for brucellosis were surveyed, and the standardized utilization rate of personal protective equipment (PPE) was 20.13% (480/2 384). The utilization rate of glove, mask, rubber shoe, and work cloth were 38.26% (912/2 384), 31.80% (758/2 384), 32.01% (763/2 384) and 30.87% (736/2 384),respectively. There were significant differences in the utilization rate and standardized utilization rate of the four types of PPE among populations in different age, occupation, educational level and area groups (all P<0.001). The utilization rate and standardized utilization rate of PPE were lower in people over 60 years old, women, farmers, and those with lower educational level. The results of multivariate analysis showed that occupation and area were the influencing factors for the standardized utilization of PPE, the standardized utilization rates of PPE were higher in herdsmen and veterinarians. The standardized utilization rate of PPE in Yanggao County and Huocheng County was significantly higher than that in Zuoyun County and Hunyuan County. Conclusions:The utilization rate of the four types of PPE in occupational population at high risk for brucellosis was not high in China, and the standardized utilization rate was low, lower than the requirement in National Brucellosis Prevention and Control Plan, and there were significant differences among different areas. It is urgent to distribute PPE to occupational population at high risk for brucellosis and carry out health education about PPE utilization. Meanwhile, it is necessary to strengthen information exchange or sharing among different areas.

Objective To explore whether liver cirrhosis markers aspartate aminotransferase-to-platelet ratio index(APRI)and fibrosis-4 index(FIB-4)based on blood biochemical indicators can predict disease free survival(DFS)and overall survival(OS)in patients with hepatocellular carcinoma(HCC)after resection.Methods 300 patients with HCC who underwent radical resection in Zhongshan Hospital,Fudan University from February 2005 to July 2017 were enrolled and the clinicopathological characteristics,recurrence and survival of these patients were retrospectively collected.The relationships between APRI,FIB-4 and postoperative recurrence and survival were evaluated.The ROC curve was used to evaluate the predictive values of APRI,FIB-4.Results The median follow-up of 300 patients was 61 months.Univariate Cox regression analysis showed that APRI,FIB-4,vascular invasion were risk factors affecting postoperative DFS and OS.The multivariate Cox regression analysis showed that vascular invasion was the independent risk factor for postoperative DFS(HR=1.518,95%CI 1.024-2.252,P=0.038)and OS(HR=2.301,95%CI 1.270-4.167,P=0.006).The time dependent ROC(time-ROC)curve showed that AUCs of APRI and FIB-4 predicting 1-year,3-year,and 5-year DFS were 0.555-0.596,which were 0.600-0.679 when predicting 1-year,3-year,and 5-year OS.Conclusions The predictive value of APRI and FIB-4 based on blood biochemical indicators alone for postoperative DFS and OS in HCC patients is limited.

Objective:To compare clinical efficacy and safety of peripheral to central pruning of apocrine sweat glands versus along small incision of apocrine sweat glands in the treatment of axillary bromhidrosis.Methods:A prospective randomized controlled study method was used to recruit patients with armpit odor admitted to the Department of Aesthetic and Plastic Surgery, Affiliated Hospital of Zunyi Medical University from June to October 2022. The patients were divided into the experimental group (underwent peripheral to central pruning of apocrine sweat glands with small incision of axillary fold under direct view) and the control group (apocrine sweat glands were cut off along the direction of small incisions) by randomization. The occurrence of postoperative complications such as hematoma, infection, skin necrosis, delayed incision healing, scar and skin contracture were observed in both groups, and the incidence rate was calculated. The surgical effect was evaluated 6 months after the operation, and the number of cured, markedly effective, and ineffective sides was counted, and the cure rate and effective rate were calculated; the satisfaction was investigated and divided into two options: satisfactory and dissatisfied, and the satisfaction rate was calculated. Count data were analyzed using the chi-square test. P<0.05 indicated that the difference was statistically significant. Results:A total of 52 patients were recruited. Experimental group, 26 patients (52 side), 6 male, 20 women, aged 18-31 years, mean of 22 years; control group, 26 patients (52 side), 6 male, 20 women, aged 18-47 years, mean of 21 years. The incidence of postoperative complications in the experimental group was 3.85% (2 / 52), which was lower than 19.23% (10/52) of the control group, with statistically significant difference ( χ2=3.98, P=0.046), in which the flap necrosis, local contracture, scarring and delayed incision healing were better than the control group. The postoperative response rate in both groups was 100%(52/52), but the cure rate in the experimental group was higher than the control group [96.15% (50/52) vs. 80.77% (42/52)], with a significant difference ( χ2=6.03, P=0.014). The satisfaction rate of the experimental group was 96.15% (50/52), higher than the 82.69% (43/52) of the control group, and the difference was statistically significant ( χ2=4.92, P=0.026). Conclusion:Compared with the traditional small incision of peripheral to central pruning method and the traditional small incision of apocrine sweat glands method, the cure rate of the former is higher, which can effectively protect the skin flap dermis and subdermal vascular network around the incision, reduce postoperative skin necrosis and scar, and improve patient satisfaction.

Objective To investigate the intervention effects of Yangqing Chenfei Fang (YCF), Baojin Chenfei Fang (BCF), and Jinshui Chenfei Fang (JCF) at different pathological stages of silicosis in a rat model. Methods A total of 216 specific pathogen free rats were randomly divided into control group, silicosis group, tetrandrine group, YCF group, BCF group and JCF group, with 35-36 rats in each group (11-12 rats at each time point). The rats in control group were treated with intragastric administration of pure water [administration volume at 2.5 mL/(kg·time)], while the rats of other five groups were treated with silica suspension at 250 mg/kg body weight to induce a silicosis model using the one-time non-exposed tracheal method. Intragastric administration of the corresponding drugs was performed at three time points at days 1-14 (early stage of silicosis), days 15-28 (middle stage of silicosis), and days 29-42 (late stage of silicosis) after modeling. Pulmonary function enhanced pause (Penh), forced vital capacity (FVC), and dynamic lung compliance (Cdyn) of rats in the six groups was assessed on days 15, 29, and 43 after modeling. Histopathological changes in lung tissues were observed, and relative expression levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β, hydroxyproline, collagenⅠ(COL-Ⅰ), and α-smooth muscle actin (α-SMA) were detected in lung tissues. Results i) Pulmonary function index. The index of Penh in three stages of silicosis of rats in YCF group, BCF group and JCF group was lower than that in the silicosis group at the same stage (all P<0.05), and the index of Penh was higher than that in the tetrandrine group at the same stage (all P<0.05). The index of FVC of rats in YCF group, BCF group and JCF group at the middle stage was higher than that in the silicosis group at the same stage (all P<0.05), as well as the index of Cdyn was higher than that in the tetrandrine group at the same stage (all P<0.05). ii) Histopathology of lung tissue. Rats of the silicosis group exhibited alveolitis, fibro stripe, and collagen deposition in lung tissues in the early stage compared with rat of the control group, with fibrosis progressively worsening over time and inflammation persisting throughout the disease course. Pathological changes of lung tissues were alleviated to varying degrees in the tetrandrine groups, YCF group, BCF group and JCF group compared with that of the silicosis group. Compared with the same stage of silicosis group, the Ashcroft scores of lung tissues in the YCF group and BCF group were lower in the middle and late stages (all P<0.05). The Ashcroft score of lung tissues in the BCF group in the middle and late stages was lower than that in tetrandrine group at the same stage (all P<0.05), while the Ashcroft score in the middle stages was lower than that in YCF group at the same stage (P<0.05). The Ashcroft score of lung tissue in the JCF group was lower than that in the silicosis group, tetrandrine group and YCF group at all three stages (all P<0.05), and was lower than that in BCF group at the early and late stage of silicosis (all P<0.05). iii) Inflammatory factors. IL-6 level in the lung tissues in the YCF group, BCF group and JCF group decreased compared with that in the silicosis group at the same stage (all P<0.05), while IL-1β and TNF-α levels decreased at the early and middle stages (all P<0.05), hydroxyproline level decreased at all three stages (all P<0.05). iv) Collagen. The relatively expression of COL-Ⅰ in the lung tissues in the YCF group decreased at the late stage of silicosis compared with that in the silicosis group at the same stage (all P<0.05), while the relatively expression of α-SMA decreased at the middle and late stages (all P<0.05). Compared with the same stage of silicosis group, the relative expression of COL-Ⅰ and α-SMA of the lung tissues reduced in the BCF group and JCF group at all stages (all P<0.05). The relative expression of COL-Ⅰ of the lung tissues reduced in the BCF group at the late stage compared with that in the YCF group in the same stage (all P<0.05), while the relative expression of α-SMA decreased at the early and middle stages (all P<0.05). The relative expression of COL-Ⅰ of the lung tissues reduced in the JCF group at late stage of silicosis (all P<0.05), while the relative expression of α-SMA decreased at all three stages (all P<0.05), compared with the same stage of YCF group. Conclusion All three formulations of Chinese herbs are effective in improving lung function and alleviating the progress of lung inflammation and fibrosis. YCF is the most effective in suppressing inflammation in the early stage of silicosis. BCF excels in delaying fibrosis in the early and middle stages. JCF is the most effective in improving lung function and delaying fibrosis progression in the late stage.

Objective:To understand the current status of knowledge of brucellosis prevention and control among occupational groups at high-risk of brucellosis, and to provide a scientific basis for assessing the effectiveness of brucellosis prevention and control in China.Methods:A total of four counties in Shanxi Province and Xinjiang Uygur Autonomous Region were selected as survey counties from 2019 to 2020, and 600 people from the occupational groups at high-risk of brucellosis in each survey county were selected as survey respondents, and basic information and knowledge of prevention and treatment were collected through questionnaires. Single-factor and multi-factor logistic regression models were used to analyze the factors affecting the population's knowledge of prevention and treatment.Results:A total of 2 411 people participated in the survey and 2 384 valid questionnaires were obtained, including 1 405 males and 979 females, with the youngest age being 18 years old, the oldest being 91 years old, and the median being 57 years old. The overall knowledge of brucellosis prevention and control was 17.74% (423/2 384). The knowledge rate was lower among people over 60 years old, farmers, and people with less than elementary school education (13.99%, 14.50%, and 13.78%), and higher among women, herders, and people with elementary school education (20.02%, 36.33%, and 19.58%); the knowledge rate was lower in Hunyuan County (0.51%), and the differences in overall knowledge rates by age, occupation, education level, and region were statistically significant (χ 2 = 18.25, 87.18, 11.05, 197.43, P < 0.001). Multi-factor logistic regression analysis showed that gender, occupation, literacy and region were associated with knowledge of prevention and treatment ( P < 0.05). Conclusions:The overall knowledge of prevention and treatment among high-risk occupational groups in the key areas of China's brucellosis prevention and treatment program is low, with a large gap with the goals of the national brucellosis prevention and treatment program, and gender, occupation, literacy level, and region are the influencing factors of the knowledge of prevention and treatment. There is an urgent need to carry out a variety of health education activities for high-risk occupational groups and to strengthen the exchange of experience on brucellosis prevention and treatment between regions.
