ObjectiveThis paper aims to analyze the damage degree of muscle tone in rats with spasticity of cerebral apoplexy (SCA) and the expression of Nestin and β-catenin in the M1 region of the cerebral cortex, thereby investigating the action mechanism of different doses of Shaoyao Gancaotang on rats with SCA. MethodsThe rats were randomly divided into a blank group, a model group, a positive control group (baclofen, 5.25 mg·kg-1), and low, medium, and high-dose groups of Shaoyao Gancaotang (2.1, 4.2, 8.4 g·kg-1), with nine rats in each group. A rat model with SCA was established by using a modified phrenic nerve block combined with intraventricular injection of anhydrous ethanol. Following behavioral scoring to confirm model validity, drug interventions were conducted. Neurological deficits and muscle tone were evaluated by behavioral assessments. The open field test was used to measure locomotor distance. Transmission electron microscopy was employed to examine the synaptic structures. Skeletal muscle adenosine triphosphate (ATP)ase staining was used to analyze myofibrillar changes. Hematoxylin and eosin (HE) staining was used to observe the histomorphological changes. Immunohistochemistry, Real-time polymerase chain reaction (Real-time PCR), and Western blot were employed to detect mRNA levels and protein expressions of Nestin and β-catenin in the M1 region of the cerebral cortex. ResultsCompared with the blank group, rats in the model group exhibited significantly increased neurological deficit scores (P<0.01), markedly elevated muscle tone scores (P<0.01), substantially reduced locomotor distance (P<0.01), prominent structural swelling and blurring, severe destruction of cerebral cortical cells, a significant increase in the proportion of skeletal muscle ATPase type Ⅰ fibers (P<0.01), a significant decrease in mRNA levels and protein expression of Nestin (P<0.01), and a significant increase in mRNA levels and protein expression of β-catenin (P<0.01). Compared with the model group, the Shaoyao Gancaotang group exhibited reduced neurological deficit scores and muscle tone scores in rats with SCA (P<0.01) and increased locomotor distance (P<0.01). Transmission electron microscopy revealed clearer and more intact synaptic structures in the rats from the Shaoyao Gancaotang group, with increased vesicle numbers and improved morphology. HE staining revealed intact neuronal cell structures with regular arrangement and reduced vacuolated cells in the rats from Shaoyao Gancaotang. ATPase staining result indicated a decreased proportion of type Ⅰ muscle fibers in the rats from the Shaoyao Gancaotang group (P<0.01). Real-time PCR results demonstrated increased mRNA expressions of Nestin and β-catenin in the rats from the Shaoyao Gancaotang group (P<0.01). Immunohistochemistry and western blot analyses indicated elevated protein expressions of Nestin and β-catenin in rats with SCA from the Shaoyao Gancaotang group (P<0.05, P<0.01). ConclusionShaoyao Gancaotang may improve neurological function impairment and limb spasticity in model rats with SCA by regulating the proliferation and differentiation of neural stem cells in the cerebral cortex M1 region.

Background As a traditional labor-intensive industry, the wooden furniture manufacturing sector has been facing significant occupational health hazards, notably noise exposure. Objective To understand the current status of occupational health management and workplace noise monitoring in the wooden furniture manufacturing industry in Foshan City of Guangzhou Province over the past five years (2020−2024), to clarify the exposure level of occupational noise hazards in this industry, the implementation of prevention and control measures, and their dynamic changing trends, and to provid a reference basis for formulating and optimizing targeted occupational health supervision strategies. Methods By judgment sampling method, 381 wooden furniture manufacturing enterprises in Foshan City from 2020 to 2024 were selected. Through document review, on-site investigation, and on-site testing, the basic information of the enterprise, key indicators of occupational health management (declaration of projects with occupational disease hazards, occupational health training, the setting and effect of occupational disease prevention facilities, the allocation and use of personal protective equipment, occupational health examinations, etc.) and monitoring data of noise intensity in the workplace were systematically collected. Descriptive statistical analysis was adopted to present the characteristics of enterprises and various indicators, and trend tests were used for dynamic changes of occupational health management indicators and noise intensity monitoring results between each year. Results Among the 381 enterprises, small and micro enterprises accounted for 94.0% (358/381), the overall occupational hazard exposure rate of workers was 56.7% (15199/26798), and the noise exposure rate was 45.6% (12221/26798). The report rate of projects with occupational disease hazards was 100%, the occupational health training rate of exposed workers was 69.6%, the setting rate and effectiveness rate of noise prevention facilities were 24.9% and 95.8% respectively, the distribution rate and effective wearing rate of noise protection earplugs/earmuffs were 77.6% and 87.1% respectively, and the rate of occupational health examinations for noise-exposed workers and the abnormal rate were 55.4% and 2.5% respectively. The trend analysis results showed that the rates of occupational health training, setting and effectiveness of noise prevention facilities, distribution and effective wearing of noise protection earplugs/earmuffs, occupational health examinations for noise-exposed workers, and abnormal health examination results all showed an overall upward trend (P values were all<0.05). The proportion of workplace noise intensity greater than 85 dB(A) and the rate of noise exceeding standards at work positions both showed an overall upward trend (P values were both<0.01). Conclusion During the period from 2020 to 2024, the occupational health management in the wooden furniture manufacturing industry in Foshan City has achieved certain positive progress, particularly in areas such as the installation of protective facilities, the use of personal protective equipment, and the implementation of occupational health examinations. However, workplace noise hazards have not been effectively controlled. Moving forward, regulatory efforts must consolidate existing management achievements while strengthening mandatory requirements and support for the technical transformation of high-noise processes and the widespread adoption of noise reduction facilities. This approach is essential to fundamentally curb occupational noise hazards.

Breast cancer is a kind of malignant tumor with a complex mechanism, and its morbidity and mortality are increasing year by year, which seriously threatens women's health. At present, the main clinical treatments are surgical resection, radiotherapy, chemotherapy, and drug therapy, but they are often accompanied by side effects and adverse reactions, which affect the therapeutic effect. Traditional Chinese medicine (TCM) has the advantages of multi-component and multi-target treatment in the fight against breast cancer. The wnt/β-catenin signaling pathway is one of the classic pathways in cancer research. Abnormally activated Wnt/β-catenin signaling pathway inhibits β-catenin degradation by blocking the formation of Axin/glycogen synthase kinase 3β/adenomatous polyposis coli complex, thus promoting β-catenin nuclear metastasis, and it binds to T cell transcription factor/lymphoenhancer factor-1 to initiate downstream target genes and further interfere with the proliferation, migration, and invasion of tumor cells to affect the tumor process. Previous studies have shown that TCM monomers and compounds can mediate the Wnt/β-catenin signaling pathway to inhibit the malignant phenotype of breast cancer cells, thus playing an anti-breast cancer role, and the biochemical process involved in the regulation of therapeutic drugs has not been systematically combed. By analyzing and collating Chinese and foreign literature at the present stage, this paper discussed the association mechanism between Wnt/β-catenin signaling pathway and breast cancer and analyzed the internal mechanism of TCM monomers and compounds in mediating Wnt/β-catenin signaling pathway to exert anti-breast cancer effect. The statistical results showed that the flavonoids, alkaloids, and terpenoids in TCM monomers could target the Wnt/β-catenin signaling pathway and block the further development of malignant phenotype of breast cancer cells. TCM compounds with functions of clearing heat and detoxifying, promoting blood circulation and removing blood stasis, and tonifying kidney and liver were commonly used to intervene in the Wnt/β-catenin signaling pathway to prevent breast cancer. Compared with the current inhibitors of Wnt/β-catenin signaling pathway, the application of TCM monomers and compounds is expected to bring low-toxicity and high-efficiency breast cancer treatment drugs to the clinical practice, and the existing results provide a reference for the subsequent screening, research, and development of TCM small-molecule compounds and TCM compounds against breast cancer.

Objective:To investigate the characteristics of the population of skeletal fluorosis patients in drinking-tea-borne endemic fluorosis (referred to as drinking-tea-borne fluorosis) areas in Inner Mongolia Autonomous Region (referred to as Inner Mongolia) and the influencing factors of treatment willingness, and to provide a basis for improving the prevention and control measures of drinking-tea-borne fluorosis and the treatment plan of skeletal fluorosis.Methods:From August to October 2022, a face-to-face questionnaire survey was conducted in key areas of drinking-tea-borne fluorosis in Inner Mongolia (administrative villages with an average daily intake of tea fluoride > 3.5 mg and skeletal fluorosis patients identified by the general survey of drinking-tea-borne fluorosis in Inner Mongolia in 2019), and to investigate the demographic, severity, and treatment status of patients with skeletal fluorosis, analyze the demographic characteristics of patients with skeletal fluorosis and the influencing factors of treatment willingness.Results:A total of 734 patients with skeletal fluorosis were investigated, including 543 mild cases, 125 moderate cases and 66 severe cases. The gender ratio of patients with skeletal fluorosis was 0.71 ∶ 1.00 (305/429), the age was concentrated in > 50 - 70 years old (70.57%, 518/734), the proportion of Mongolians was 94.28% (692/734), the proportion of herders was 97.68% (717/734), the educational level was mainly primary school (54.63%, 401/734), and the proportion of poor households and immigrants who had moved to their current residence was 7.08% (52/734) and 8.04% (59/734), respectively. The distribution of the severity of skeletal fluorosis in patients of different ages, genders, and educational levels was compared, and the differences were statistically significant ( P < 0.05). Fifty-three point two seven percent (391/734) of the patients had a willingness to undergo non-pharmacological treatment, of which 69.82% (273/391) had already started non-pharmacological treatment, with a treatment effectiveness rate of 73.99% (202/273). Sixty-five point two six percent (479/734) of the patients had a willingness to receive medication treatment, of which 7.31% (35/479) had already started medication treatment, with a treatment effectiveness rate of 54.29% (19/35). Zero point two seven percent (2/734) of the patients expressed a willingness to undergo surgical treatment, while no patients underwent surgical treatment. Multivariate logistic regression analysis showed that the age, ethnicity, occupation, educational level, poverty status, immigrants status, and the severity of skeletal fluorosis were all influencing factors of non-pharmacological treatment willingness ( P < 0.05). Occupation, educational level, poverty status, immigrants status, and the severity of skeletal fluorosis were all influencing factors of medication treatment willingness ( P < 0.05). Conclusions:Patients with skeletal fluorosis caused by tea drinking in Inner Mongolia are mainly from Mongolian ethnic groups, herders, middle-aged and elderly people, and those with a lower educational levels. The willingness of patients to receive treatment is influenced by various factors, and corresponding intervention measures can be formulated and taken based on these influencing factors to effectively improve the disease prevention awareness and treatment willingness of patients and the public.

Objective:To explore the value of ultrasound elastography (USE) in evaluating the stability and prognosis of carotid plaque (CP) in patients with cerebral infarction(CI).Methods:A total of 94 patients with CI admitted to Dongying District People′s Hospital of Dongying City from January 2022 to December 2023 were retrospectively selected as the study objects, all of whom were treated with carotid artery dissection. The presence of CP was confirmed by pathological examination. The head and neck of patients were examined by conventional ultrasound and USE before surgery, respectively, and the diagnostic value of the two methods on CP stability was compared. The difference of strain value and strain rate among different plaque types was compared, and the correlation between different plaque types and the score of ESSEN Stroke Risk Scale (ESRS) was analyzed.Results:The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of conventional ultrasonic detection of CP were 75.00%, 71.43%, 74.00%, 87.10% and 52.63%; and of USE were 90.28%, 89.29%, 90.00%, 95.59%, 78.13%. The strain values and strain rates of stable plaques were lower than those of vulnerable plaques : (0.73 ± 0.11) × 10 3 vs. (2.42 ± 0.57) × 10 3, (6.57 ± 0.84) s -1 vs. (9.36 ± 2.55) s -1, there were statistical differences ( P<0.01). The ESRS scores of patients with vulnerable plaques were mostly ≥3 scores, and those with stable plaques were mostly<3 scores, there was statistical differences ( P<0.01). The scores of National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) 3 months after the onset of stable plaque were lower than those of vulnerable plaque patients: (26.80 ± 8.47) scores vs. (34.67 ± 8.98) scores, (3.97 ± 0.84) scores vs. (4.55 ± 1.61) scores, there were statistical differences ( P<0.01 or <0.05). Conclusions:USE has significant advantages in detecting CP stability in CI patients, which can efficiently and accurately assess the risk of plaque and provide important information for clinical use.

The incidence of adenocarcinoma of esophagogastric junction (AEG) has been increasing annually. Due to its unique anatomical location and functional characteristics, the surgical operating space is limited, and the procedure is technically challenging, leading to a relatively high rate of intraoperative and postoperative complications. These issues are particularly pronounced in cases involving higher esophageal invasion. In recent years, with the advancement and maturation of laparoscopic techniques, the procedure of transabdominal hiatal high esophageal transection and anastomosis has been further refined and optimized. This has enabled gastrointestinal surgeons to perform the operation more smoothly, reduce operative time, and decrease the incidence of related complications. By reviewing relevant literatures and summarizing the operational experience of our team, the authors discuss the application value of transabdominal hiatal high esophageal transection and anastomosis in the radical resection of AEG, aiming to improve the success rate of surgery and reduce the incidence of complications.

To verify whether chaperones can promote the soluble expression of PlpE in Escherichia coli and whether the expressed protein is active,prokaryotic expression and Western blot detection were performed.The results showed that:The PlpE prokaryotic expression vector pET-32a(+)-plpE was expressed as inclusion body,and the expression form was not changed by changing the concentration of inducer,induction time and temperature.The companion proteins pG-KJE8,pGro7,pKJE7 and pG-Tf2 were co-expressed with pET-32a(+)-plpE in Eschierichia coli expres-sion system,respectively.When the final concentration of IPTG of 0.5 mmol/L,L-arabinose of 0.5 g/L or tetracycline of 5.0 μg/L were added as inducers and induced at 37 ℃ for 8 h,the results showed that the molecular companion pGro7 could change the expression of rp-PlpE from inclu-sion body to soluble expression.pG-KJE8,pKJE7 and pG-Tf2 had no effect on the expression of rp-PlpE.The soluble rp-PlpE can react specifically with the positive serum of Mannheimia haemolyti-ca.Therefore,the study showed that the co-expression of the chaperone protein pGro7 can make the rp-PlpE protein express in a soluble form,and the purified protein exhibits reactogenicity.These findings lay the foundation for the establishment of a subunit vaccine and serological diagno-sis methods for Mannheimia haemolytica.
