ObjectiveTo investigate the molecular mechanism by which the Bushen Kaixuan Tongluo prescription exerts a renal protective effect in mice with diabetic kidney disease (DKD) by regulating the cyclic adenosine monophosphate (cAMP) signaling pathway. MethodsThirty specific pathogen-free (SPF) male db/db mice were adaptively fed for three weeks. Mice with a random tail vein blood glucose level ≥ 11.1 mmol·L-1 and urinary albumin-creatinine ratio (ACR) ≥ 30 mg·g-1 were considered successfully modeled. The successfully modeled mice were randomly divided into five groups with six mice in each group: the model group, the low-, medium-, and high-dose Bushen Kaixuan Tongluo prescription groups (administered at doses of 7, 14, 28 g·kg-1·d-1 respectively), and the positive drug irbesartan group (administered at a dose of 20 mg·kg-1·d-1). Additionally, six db/m mice were selected as the blank group. Mice in each group were given intragastric administration of the Bushen Kaixuan Tongluo prescription at the corresponding concentrations, irbesartan, or an equal volume of pure water, and the intervention lasted for 12 weeks. During the experiment, the general conditions, body weight changes, and renal function indicators of the mice were dynamically monitored. After the intervention, a blood glucose meter was used to measure the fasting blood glucose (FBG) of the mice. An automatic biochemical analyzer was employed to detect the levels of serum creatinine (SCr), blood urea nitrogen (BUN), urinary microalbumin (uALB), ACR, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol (TC), triglycerides (TG), leptin (LEP), glycosylated serum protein (GSP), and insulin (INS) in the mice. Renal tissues were collected for hematoxylin-eosin (HE) staining, periodic acid-Schiff (PAS) staining, and Masson's trichrome staining to observe the histopathological changes. Immunohistochemistry (IHC) was used to detect the expressions of protein kinase A (PKA) and cAMP response element-binding protein (CREB) in the mice. Western blot analysis was performed to determine the expression levels of PKA, phosphorylated protein kinase A (p-PKA), CREB, phosphorylated cAMP response element-binding protein (p-CREB), and B-cell lymphoma-2 (Bcl-2) proteins in the renal tissues of the mice. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression levels of PKA, CREB, and Bcl-2 in the renal tissues of the mice. ResultsCompared with the blank group, the mice in the model group showed listlessness, decreased activity, and a significant increase in body weight (P<0.01). Biochemical indicators revealed that the levels of BUN, uALB, ACR, AST, ALT, TC, TG, FBG, LEP, GSP, and INS were significantly increased (P<0.01), while SCr showed an increasing trend with no statistically significant difference. Compared with the model group, the mice in the Bushen Kaixuan Tongluo prescription intervention groups had improved general conditions and a decreasing trend in body weight. Biochemical indicators showed that the levels of BUN, uALB, ACR, TC, GSP, and INS were significantly decreased (P<0.05), while SCr, AST, ALT, TG, and LEP showed a decreasing trend with no statistically significant difference. Renal histopathological analysis showed that the model group exhibited typical DKD pathological features such as thickening of the glomerular basement membrane, expansion of the mesangial matrix, and deposition of collagen fibers in the renal tubulointerstitium, and all treatment groups could alleviate the above pathological damages. The IHC results showed that compared with the blank group, the expression levels of p-PKA and p-CREB in the renal tissues of the model group were significantly decreased (P<0.01). Compared with the model group, the expression level of p-PKA in the medium-dose Bushen Kaixuan Tongluo prescription group was significantly increased (P<0.01), while the expression level of p-CREB showed an increasing trend with no statistically significant difference. Western blot results showed that compared with the blank group, the expression levels of p-PKA/PKA, p-CREB/CREB, and Bcl-2 in the model group were significantly decreased (P<0.05). Compared with the model group, the expression levels of these proteins in the medium-dose Bushen Kaixuan Tongluo prescription group were significantly increased (P<0.01). Real-time PCR results showed that compared with the blank group, the mRNA expressions of PKA, CREB, and Bcl-2 in the model group were significantly down-regulated (P<0.05). Compared with the model group, the mRNA expressions of these genes in the medium-dose Bushen Kaixuan Tongluo prescription group were significantly up-regulated (P<0.05). ConclusionThe Bushen Kaixuan Tongluo prescription can improve the liver and kidney functions of db/db mice, correct lipid metabolism disorders and glucose metabolism imbalance. Its renal protective effect is associated with up-regulating the cAMP signaling pathway to improve renal fibrosis and reduce the level of oxidative stress, thereby protecting renal function.

With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

OBJECTIVE To clarify the current development status of clinical pharmacist training bases and the pharmacist workforce in China, and to provide evidence for standardizing base construction and promoting the high-quality development of hospital pharmacy. METHODS Questionnaires were distributed to all clinical pharmacist training bases for urgently-needed health professionals and clinical pharmacist training bases under the Chinese Hospital Association that had been approved by the end of 2023 to collect data including base profiles and pharmacist staffing conditions. Expert teams carried out field investigations to verify the collected data. Descriptive statistical analyses were conducted on the quantity, type and regional distribution of training bases, and the influencing factors of pharmacist staffing in the bases were analyzed. RESULTS Field surveys were completed covering 297 training bases across 31 provincial-level administrative regions. Among the base hospitals, 87.88% were Grade A tertiary general hospitals, and 65.32% were located in provincial capitals. The eastern region had the largest number of bases (136, accounting for 45.79%), followed by the western region (79, 26.60%). Great disparities existed among provinces in terms of base quantity and hospital scale. The median proportion of pharmaceutical technical personnel in base hospitals was 4.05%, and the median number of clinical pharmacists per 100 hospital beds was 0.53. Both indicators reached the highest in the eastern region (0.57, 4.43%) and the lowest in the northeastern region (0.45, 3.01%). A total of 3 627 full-time clinical pharmacists were employed in all surveyed bases, among whom 83.68% held clinical pharmacist training certificates, 35.43% possessed senior professional titles, and 78.19% had postgraduate or higher educational background. The total annual training capacity of the surveyed bases was 4 291 trainees, with obvious differences in annual training capacity across regions and provinces. Training specialties covered 19 specialized disciplines plus one general discipline, and no province could deliver training for all 20 specialties simultaneously. Multivariate Logistic regression analysis showed that geographic region exerte d a significant impact on the proportion of pharmaceutical technical personnel (≥4%) ( P <0.05), while the approval time of training bases and hospital scale had significant effects on the number of clinical pharmacists per 100 beds (≥0.6) ( P <0.05). CONCLUSIONS China’s clinical pharmacist training system has basically matured and taken initial shape. The distribution of clinical pharmacist training resources is generally consistent with regional population and economic development levels. However, the allocation of pharmaceutical staff and clinical pharmacists has not yet met national standards and clinical service demands.

ObjectiveCell adhesion is a critical process that regulates cellular physiological functions. Quantitative characterization of adhesion dynamics is essential for elucidating the intrinsic mechanical mechanisms underlying cellular activities. Although atomic force microscopy-based single-cell force spectroscopy is widely used for single-cell adhesion measurements, it requires complex chemical modifications for preparation of live-cell probes, leading to limitations such as cumbersome operation, low throughput, and potential impacts on cell viability. Fluidic force microscopy, which combines atomic force microscopy with microfluidic probes, is a technique allowing the operation of force-controlled nanopipettes in aqueous environments. By applying negative or positive pressure via a pressure controller, a single living cell can be captured onto or released from the cantilever under physiological conditions. This procedure offers a simple workflow and high assay throughput for single-cell adhesion measurements without the need for chemical functionalization. In this study, fluidic force microscopy-based single-cell force spectroscopy was adopted to achieve long-term quantitative characterization of single-cell adhesion dynamics in a simpler and more efficient manner, comparing the dynamic differences in adhesion establishment between two cell lines with different differentiation levels. MethodsHEK 293T and hTERT RPE-1 cells were non-invasively captured on the cantilever of a fluidic force microscope via its integrated microfluidic system during 40 h of adhesion culture. Cell-substrate detachment assays were performed, and force-distance curves were recorded to extract key mechanical adhesion parameters, including adhesion force, adhesion energy, and maximum detachment distance. These measurements were combined with real-time monitoring of cell spreading area to systematically characterize the dynamic evolution of single-cell adhesion. ResultshTERT RPE-1 cells rapidly entered a stable adhesion phase within 1 h after seeding, with both area-normalized adhesion force and area-normalized adhesion energy reaching peak values. In contrast, HEK 293T cells required 4 h to achieve stable adhesion. Subsequently, the adhesion force, adhesion energy and maximum detachment distance of hTERT RPE-1 and HEK 293T cells stabilized at approximately 240 nN vs. 30 nN, 2.2 pJ vs. 0.12 pJ and 6 μm vs. 4 μm, respectively. hTERT RPE-1 cells reached the peak of area-normalized adhesion parameters earlier than HEK 293T cells, with their peak area-normalized adhesion force and area-normalized adhesion energy being substantially elevated relative to HEK 293T cells. HEK 293T cells presented stronger linear correlations among adhesion energy, maximum detachment distance and adhesion force compared with hTERT RPE-1 cells. For both cell lines, cell spreading area exhibited a weak correlation with adhesion force. Whereas the area-normalized adhesion parameters of HEK 293T cells remained relatively constant throughout the adhesion process, hTERT RPE-1 cells exhibited elevated values in the early phase, followed by a gradual decline. These results indicated distinct dynamic adhesion patterns between the two cell types, with hTERT RPE-1 cells exhibiting stronger adhesion strength and higher adhesion efficiency. ConclusionIn this study, fluidic force microscopy-based single-cell force spectroscopy was successfully applied to perform long-term in situ quantitative measurement of the adhesion dynamics in single adherent cells. The approach revealed divergent adhesion patterns between HEK 293T and hTERT RPE-1 cells, suggesting a close association between cell differentiation and adhesion behaviors. These findings provide quantitative mechanical evidence for further understanding the underlying mechanisms of cell adhesion.

OBJECTIVE To investigate the current status of quality management in clinical pharmacist training bases in China, and to provide references for the standardized development and improvement of these bases. METHODS A combined approach of questionnaire survey and on-site investigation was adopted, targeting the healthcare highly sought-after talent (clinical pharmacist) training bases in 31 provinces of China as well as the clinical pharmacist training bases affiliated with the Chinese Hospital Association. A training quality management evaluation index system consisting of 25 tertiary indicators was established. Investigations were conducted from two dimensions: structural quality of training and quality management of training processes. Data were statistically analyzed using descriptive statistical methods. RESULTS On-site investigations were completed for 297 clinical pharmacist training bases across the 31 provinces, among which 284 were affiliated with the Chinese Hospital Association and 271 were healthcare highly sought-after talent (clinical pharmacist) training bases. In terms of structural quality, the core indicator compliance rate for hospital-level training systems exceeded 80%, the rate of special fund utilization for designated purposes reached 80.13%, and the overall compliance rate for software and hardware facilities surpassed 88%. A total of 1 348 preceptors were employed across the training bases, among whom those with senior professional titles and full-time specialist clinical pharmacists as lead preceptors accounted for 62.91% and 94.36%, respectively. Regarding process quality, the compliance rate for “establishment of clinical practice teaching groups in accordance with regulations during clinical department rotations” was 85.19%, and 79.80% and 76.09% of the bases were found to implement strict confidentiality in theoretical examinations and meet the required scale of assessment cases, respectively. However, formal documents of corresponding training management regulations were formulated in only 57.91% of the bases, and the completeness and standardization rate of training manual completion was merely 47.47%. In addition, considerable disparities in quality management levels were observed among provinces, with issues in training process quality being particularly prominent. CONCLUSIONS The management system, hardware facilities, and preceptor staffing of clinical pharmacist training bases in China are relatively well-established, yet notable variations in quality management exist among training bases across different provinces.

Objective To analyze the characteristics of hearing loss at different frequencies among noise-exposed workers in a lithium battery manufacturing enterprise. Methods A total of 1 954 noise-exposed workers from a large lithium battery manufacturing enterprise were selected as the study subjects using the judgmental sampling method. Pure-tone audiometry, individual noise exposure level monitoring, and workplace noise intensity measurement were conducted. Results The overall detection rate of hearing loss among the study subjects was 39.0%. The detection rates of unilateral and bilateral hearing loss were 21.0% (410/1 954) and 18.0% (352/1 954), respectively. The detection rate of hearing loss in the right ear was higher than that in the left ear (30.1% vs 26.9%, P<0.05). The detection rates of elevated hearing thresholds at high frequencies and speech frequencies were 38.8% and 1.1%, respectively. Comparisons of the detection rates of elevated hearing thresholds across different frequencies between the left and right ears showed significant differences (all P<0.01); specifically, the detection rate at 4.0 kHz in the right ear was higher than that in the left ear (P<0.01). The detection rates of elevated hearing thresholds at 2.0, 4.0, and 6.0 kHz increased with longer duration of noise exposure (all P<0.05). Except at 1.0 kHz, the detection rates of elevated hearing thresholds at 0.5, 2.0, 3.0, 4.0, and 6.0 kHz showed increasing trends with age (all P<0.05). Conclusion Hearing loss among noise-exposed workers in the lithium battery manufacturing industry is predominant in the high-frequency type, with the highest sensitivity at 4.0 kHz and greater susceptibility in the right ear. The detection rate of high frequency hearing loss increases with longer noise exposure duration and advacing age. Health surveillance should focus on workers with longer noise exposure duration and older age. Noise control measures should be strengthened.

OBJECTIVE To investigate the mechanism of Shenling baizhu san (SLBZS) in ameliorating ulcerative colitis (UC). METHODS Mice were randomly divided into normal group, model group, and low-, medium-, high-dose SLBZS groups (3, 6, 12 g/kg), with 10 mice in each group. Except for the normal group, mice in other groups were given free access to 3% dextran sulfate sodium solution for 7 days to establish UC models. Simultaneously, mice in each group were intragastrically administered corresponding medicinal liquid or double-distilled water once a day for consecutive 7 days. After the last administration, the histopathological morphology of colon tissues was observed; the serum levels of inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-18 were detected; the total bile acid contents in liver, gallbladder and colon tissues were determined; the expression level of NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) in colon tissues was tested. The expression levels of flora metabolism-related proteins [G protein-coupled receptor 41(GPR41),GPR43,farnesoid X receptor (FXR), G protein-coupled bile acid receptor 1 (TGR5), flavin-containing monooxygenase 3 (FMO3), cytochrome P450 family 27 subfamily A member 1 (CYP27A1), CYP7A1] in liver or colon tissues, as well as the proteins related to Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB)/NLRP3 inflammatory axis [TLR4, NF-κB, phosphorylated NF-κB (p-NF-κB), myeloid differentiation factor 88 (MyD88), NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1] in colon tissues were measured. RESULTS Compared with the model group, the colon tissue injury and inflammatory cell infiltration were alleviated in medium- and high-dose SLBZS groups. The serum levels of TNF-α, IL-1β and IL-18, total bile acid contents in liver and colon tissues, as well as the protein expression levels of FMO3 and CYP7A1 in liver tissues, TLR4, p-NF-κB, NF-κB, MyD88, NLRP3, ASC and caspase-1 in colon tissues were significantly decreased (P<0.05). Meanwhile, the total bile acid content in gallbladder, the protein expression levels of GPR41 and GPR43 in colon tissues, along with CYP27A1, FXR and TGR5 in liver tissues were significantly increased (P<0.05). CONCLUSIONS SLBZS may relieve colonic inflammatory injury and ameliorate UC by regulating the expression of flora metabolism-related proteins and inhibiting the abnormal activation of TLR4/NF-κB/NLRP3 inflammatory axis.

ObjectiveTo investigate the mechanism by which Luoshi Neiyi prescription treats endometriosis (EMs) through the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway. MethodsAnimal experiments were conducted with 50 female SD rats, which were randomized into a sham operation group (10 rats) and a modeling group (40 rats). An autologous endometrial transplantation method was used for the modeling of EMs. The 36 successfully modeled rats were randomly allocated into four groups (n=9 each): The model group, the low-dose (7.87 g·kg-1) Luoshi Neiyi prescription group, the high-dose (15.74 g·kg-1) Luoshi Neiyi prescription group, and the dienogest (0.20 mg·kg-1) group. The physiological status and ectopic lesion volumes of rats in each group were observed. Hematoxylin-eosin (HE) staining was used to observe the morphology of the eutopic endometrial tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of inflammatory factors including interleukin-1β (IL-1β) and prostaglandin E2 (PGE2) in the serum of EMs rats. Immunohistochemistry was used to detect the expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor A (VEGFA) in the eutopic endometrial tissue. Western blot was adopted to determine the protein levels of TLR4, myeloid differentiation factor 88 (MyD88), phosphorylated nuclear factor-κB (p-NF-κB)/NF-κB, MMP-9, and VEGFA in the eutopic endometrial tissue. In the cell experiments, the cell-counting kit-8 (CCK-8) assay was employed to screen the optimal concentration of Luoshi Neiyi prescription-containing serum, and a scratch assay was performed to assess the migration ability of iheESCs cells. Interventions with Luoshi Neiyi prescription-containing serum, resatorvid (TAK-242, a TLR4 inhibitor), and lipopolysaccharides (LPS, a TLR4 agonist) were conducted, and Western blot was used to detect the expression of proteins related to the TLR4/NF-κB signaling pathway. ResultsThis experiment successfully replicated 36 EMs rat models. Compared with the sham operation group, the model group exhibited visible ectopic lesions on the abdominal wall and an increase in the writhing response score (P<0.01). Furthermore, HE staining revealed the model group exhibited a thickened eutopic epithelium, stromal cell disarrangement, and evident infiltration of inflammatory cells. In addition, the model group showed elevated serum levels of IL-1β and PGE2 (P<0.05, P<0.01), increased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue (P<0.01), and up-regulated protein levels of TLR4, MyD88, p-NF-κB/NF-κB, MMP-9, and VEGFA in the ectopic endometrial tissue (P<0.05, P<0.01). Compared with the model group, all treatment groups exhibited a reduction in the ectopic lesion volume (P<0.01). Furthermore, the writhing response scores were decreased in the high-dose Luoshi Neiyi prescription group and the dienogest group (P<0.05, P<0.01). The pathological state of the ectopic endometrial tissue was alleviated to varying degrees in the treatment groups. Low-dose Luoshi Neiyi prescription reduced serum PGE2 levels, and high-dose Luoshi Neiyi prescription and dienogest decreased serum IL-1β and PGE2 levels in EMs rats (P<0.05, P<0.01). The treatment groups showed decreased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue (P<0.05, P<0.01) and down-regulated protein levels of TLR4, MyD88, p-NF-κB/NF-κB, MMP-9, and VEGFA in the ectopic endometrial tissue (P<0.05, P<0.01). The cell experiments showed that 5%, 10%, and 20% Luoshi Neiyi prescription-containing sera significantly reduced the viability and inhibited the migration of iheESCs. Compared with the control group, 5%, 10%, and 20% Luoshi Neiyi prescription-containing serum groups and the TAK-242 group showed reduced protein levels of TLR4, MyD88, p-NF-κB/NF-κB, MMP-9, and VEGFA (P<0.01). Compared with the control group, the LPS group showed increased expression of the above proteins (P<0.01). Compared with the LPS group, the LPS+5%, 10%, and 20% Luoshi Neiyi prescription-containing serum groups showed reduced expression of the above proteins (P<0.05, P<0.01). ConclusionLuoshi Neiyi prescription may modulate the TLR4/NF-κB signaling pathway to reduce the inflammatory response and histopathological damage in the eutopic endometrium and suppress the adhesive, invasive, and angiogenic biological processes in the ectopic endometrial tissue, thereby exerting its therapeutic effect on EMs.

ObjectiveTo establish the self-reported core outcome set (COS) for patients with an example of a community study on heat-sensitive moxibustion for primary hypertension (PH), to provide a reference for the selection of effectiveness evaluation indicators in community study on heat-sensitive moxibustion. MethodsA systematic literature search was conducted to collect outcomes used in randomized controlled trials and systematic review of heat-sensitive moxibustion for PH (Jan 2021), and additional outcomes were added through patient and expert questionnaires (Feb 2021) to create a pool of outcome entries. A multidisciplinary expert Delphi survey was conducted to screen outcomes applicable to patient self-reporting (Apr 2021), and the importance of outcome indicators was rated on a 5-Point Likert Scale. Finally, patient self-reported COS was determined through a consensus conference (June 2021). ResultsA pool of patient self-reported indicators in the community study of heat-sensitive moxibustion treatment for PH was generated by standardizing and combining the outcome indicators based on the results of the literature search and the questionnaire survey, which consisted of totally 100 measurement tools or contents, excluding 51 indicators or measurement tools required measurement by specialized physicians or hospital equipment, and 49 items were retained to enter the initial list of indicator entries. For the first round of Delphi survey, the mean score for expert familiarity was 0.819, the mean score for basis of judgment was 0.710, and the expert authority coefficient was 0.765, with a total of 21 indicator measurement tools or contents deleted (significance score ≤ 75 or coefficient of variation > 0.25), 28 retained, and 3 new expert-added indicator entries added. In the second round of Delphi survey, the average score for expert familiarity was 0.859, the average score for basis for judgment was 0.763, and the expert authority coefficient was 0.811, with a total of 11 indicator measurement tools or contents deleted and 20 retained involving 5 domains. Following an expert consensus meeting, 8 outcome indicators were finalized for inclusion in the patient self-reported COS, including 6 indicators of effectiveness evaluation such as quality-of-life scores, blood pressure, traditional Chinese medicine symptom scores, cost-benefit, cardiovascular and cerebrovascular events, and adverse reactions/events, and 2 indicators of factors influencing effectiveness such as sensation of heat-sensitive moxibustion, and adherence. ConclusionIn this study, we initially established a criteria for evaluating the effectiveness in the community study on heat-sensitive moxibustion by constructing patient self-reported COS in the community study on heat-sensitive moxibustion for PH, which can provide a scientific research paradigm for the subsequent development of the community study on heat-sensitive moxibustion.
