ObjectiveTo observe the effects of Youguiwan on bone metabolism and bone morphogenetic protein-2 (BMP-2)/Smad signaling pathway in ovaries-removed rats with osteoporosis and study the mechanism of Youguiwan in the prevention and treatment of osteoporosis. MethodA postmenopausal rat model of osteoporosis was prepared by bilateral ovariectomy. The 40 female SD rats were randomly divided into five groups, including sham operation group, model group, alendronate sodium group (0.1 mg·kg-1), and high-dose and low-dose (5.36 and 2.68 g·kg-1) groups of Youguiwan. The drug was given seven days after modeling, once a day for 12 weeks. After the treatment, the changes in femur tissue structure were observed by micro-CT, including bone mineral density (BMD), bone volume/total volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), bone surface/bone volume (BS/BV), and trabecular separation (Tb.Sp). Ossification was observed by saffrane-solid green staining, and serum levels of bone metabolism markers, including bone alkaline phosphatase (BALP), osteocalcin (BGP), type Ⅰ procollagen amino terminal propeptide (PINP), and tartrate-resistant acid phosphatase 5b (TRACP-5b), were determined by enzyme-linked immunosorbent assay (ELISA). The protein and mRNA expression levels of Runx2, BMP-2, and Smad1 in rat femur were detected by Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultCompared with the sham operation group, bone trabecula in the model group was sparse. BMD, BV/TV, Tb.N, and Tb.Th were decreased (P<0.05, P<0.01). BS/BV (P<0.05) and Tb.Sp were increased. The content of BGP, BALP, PINP, and TRACP-5b in serum was significantly increased (P<0.01). The mRNA and protein expressions of Runx2, BMP-2, and Smad1 in rat femur were significantly decreased (P<0.05, P<0.01). Compared with the model group, the number of bone trabeculae in the high-dose and low-dose groups of Youguiwan was increased, and the bone microstructure was improved. BMD, BV/TV, Tb.N, and Tb.Th were increased significantly (P<0.05, P<0.01), and BS/BV and Tb.Sp were increased. The content of bone metabolic markers decreased (P<0.05, P<0.01). ConclusionYouguiwan has certain preventive and therapeutic effects on postmenopausal osteoporosis, and its mechanism may be related to promoting bone formation by regulating the BMP-2/Smad signaling pathway.

In recent years, the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine (TCM) in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine, the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances, TCM theories of etiology and pathogenesis, the role and advantages of TCM in the whole course management of pulmonary nodules, contents and methods of research on pulmonary nodules, and science popularization work, aiming to provide a reference for clinical practice and scientific research. After discussion, the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness, blood stasis, and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules, improving physical constitution, ameliorating multi-system nodular diseases, reducing anxiety and avoiding excessive diagnosis and treatment, and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present, the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed, which needs to be further studied from multiple perspectives such as clinical epidemiology, biology, and evidence-based medicine. The primary task of current research is to find out the advantages, effective prescriptions, and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time, basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized, scientific, and accurate effective diagnosis and treatment.

Objectives To analyze the spatial and temporal aggregation of multidrug resistant pulmonary tuberculosis (MDR-TB) incidence in Nanning at the township / street scale from 2017 to 2021, to explore the spatial and temporal characteristics of the spread of MDR-TB in Nanning, and to provide a scientific reference basis for the health administrative departments to achieve the precise implementation of MDR-TB prevention and control. Methods Based on the data of MDR-TB cases in Nanning from 2017 to 2021, the spatial-temporal scanning analysis software SaTScan v9.7 was used to retrospectively detect and analyze the areas where MDR-TB cases gathered. Results Through simple spatial scanning analysis, it was found that there were three first-class aggregation areas (the aggregation center was Fujiayuan Street, Jiangnan District, 2017, Xinyang Street, Xixiangtang District, 2019, and Zhonghe Town, Yongning District, 2020), and one second-class aggregation area (the aggregation center was Jinchai Town, Mashan County, 2020). Simple time scanning showed that the clustering occurred from May 2019 to December 2020. Temporal and spatial aggregation analysis showed that Xinyang Street in Xixiangtang District was the center of the first-class aggregation area, Zhonghe Town in Yongning District was the center of the second-class aggregation area, and Jinchai Town in Mashan County was the center of the third-class aggregation area. Conclusion The multidrug resistant pulmonary tuberculosis epidemic in Nanning is distributed in an aggregated manner, especially in Xinyang Street, Xixiangtang District, which has the highest spatial and temporal aggregation. It is necessary to focus on and take regional prevention and control measures to control the epidemic.

ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4(TLR4)/nuclear transcription factor-kappa B(NF-κB)/absent in melanoma 2(AIM2)inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2h4 mice were selected and randomly divided into control group, model group, low, medium and high dose groups of Buzhong Yiqitang (4.78, 9.56, 19.12 g·kg-1), and western medicine group (selenium yeast tablets, 3.033×10-5 g·kg-1). The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model, and the control group drank ad libitum distilled water. Eight weeks later, the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye, and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) was measured by enzyme-linked immunosorbent assay (ELISA), and Real-time PCR was used to detect the expression of HMGB1, TLR4, AIM2, NF-κB p65,apoptosis-associated speck-like protein(ASC),cysteinyl aspartate-specific protease-1(Caspase-1), IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 (HMGB1), TLR4, AIM2, NF-κB p65, phosphorylation(p)-NF-κB p65, ASC, Caspase-1, and IL-1β proteins in thyroid tissue, and immunofluorescence staining was used to observe the protein expression of HMGB1, AIM2, and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group, the thyroid tissue of mice in the model group was significantly swollen, the spleen quality was significantly increased, and the expression of HMGB1, TLR4, NF-κB p65, AIM2, ASC, Caspase-1, IL-1β in thyroid tissue was significantly increased (P<0.01). Compared with the model group, the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved, the quality of spleen was significantly reduced, and the expression of HMGB1, TLR4, AIM2, NF-κB p65, p-NF-κB p65, ASC, Caspase-1, IL-1β in thyroid tissue was significantly reduced (P<0.05, P<0.01). ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT, and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

ObjectiveTo analyze the satisfaction of service recipients with the preliminary assessment service of the unified elderly care needs evaluation in Shanghai, so as to provide reference for further optimization of the service system. MethodsA multi-stage random sampling method was employed to recruit participants. A total of 110 individuals who had received unified elderly care needs evaluation service in six districts of Shanghai were investigated using a structured questionnaire. SPSS 25.0 was used to analyze the data. Univariate analyses were conducted using the Chi-square test and Fisher’s precision probability test, while multivariate analysis was performed using ordinal regression. ResultsThere were differences in satisfaction with various aspects of the preliminary assessment process among participants from different areas, with those from outer suburbs generally exhibiting lower satisfaction (P<0.01). Multivariate analysis results indicated that satisfaction with the timing of the preliminary assessment was related to the service recipients’ residential area and their primary source of income; satisfaction with the service attitude and capability of the assessment personnel was only related to the residential area. Satisfaction with the preliminary evaluation results was related to the participants’ marital status, educational level, income level, and the specific rating results. ConclusionThe satisfaction level with the preliminary assessment of the unified elderly care needs assessment in Shanghai is relatively high. In the process of evaluation, a deeper analysis and exploration of individual needs based on various personal information are essential to ensure the appropriateness of the provided elderly care services, and thereby effectively enhancing recipient satisfaction.

ObjectiveTo clarify the perception of the work and satisfaction levels among personnel conducting unified elderly care needs assessment in Shanghai, to analyze the factors influencing their job satisfaction, and to provide references for optimizing the job satisfaction of unified elderly care needs assessment personnel in Shanghai. MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences, while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work, 92.5% of the surveyed personnel believed their work was important. Moreover, 87.1% were interested in their assessment tasks, and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction, 83.9% of the participants were satisfied with their assessment work, 78.5% considered the workload appropriate, and 74.2% found the working hours suitable. Additionally, 65.6% expressed satisfaction with the level of cooperation from the assessment subjects, while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging, respectively. Furthermore, 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation, workload, time spent on the job and institutional support related to external assistance, job suitability, teamwork, and client cooperation (P<0.05), while motivational factors included recognition of the significance of the job, sense of achievement, interest in the job, sense of belonging, and opportunities for personal growth (P<0.05). ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process, establish a professional team of assessment personnel, and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.
