ObjectiveTo evaluate the detection specificity for clinical samples and the detection capability for standard substances of five commercially available multiplex polymerase chain reaction (PCR) nucleic acid detection kits (hereinafter referred to as the kits) for respiratory pathogens, and to provide a reference for selecting appropriate detection kits for multi-pathogen nucleic acid testing of respiratory infections. MethodsA total of 60 respiratory pathogen-positive clinical samples with known redults were selected and tested using the five kits (labeled as A, B, C, D, and E). The detection rates and Kappa coefficients were calculated to evaluate the consistency between the results from these kits and those from single-pathogen PCR kits. According to the limit of detection (LOD) provided by the kits, standard substances of respiratory pathogens (including 12 types such as influenza virus, Mycoplasma pneumoniae, and Bordetella pertussis) were diluted to four concentrations (250, 500, 1 000, and 2 000 copies·mL⁻¹). All five kits were used for detection to evaluate their respective detection capabilities. ResultsCompared with the results from single-pathogen PCR kits, the five tested kits demonstrated good consistency (all Kappa >0.80). Among them, Kit A had the highest detection rate (100.00%), followed by Kits C and E (98.33%), and then Kits B and D (95.00%). All five kits showed a relatively low false negative rate (FNR) for samples with a cycle threshold (Ct) value ≤35 (≤2.38%). However, for samples with Ct values>35, the FNR increased accordingly(average FNR=6.67%, P=0.029). Kit C exhibited the highest detection sensitivity for the tested standard substances (average LOD: 458.33 copies·mL⁻¹), followed by Kit D, then Kits A/E, and finally Kit B. ConclusionThe five multiplex PCR kits showed good consistency with single-pathogen detection results, but each had its own performance emphasis. Kit A, with the highest detection rate and high throughput, is suitable for targeted viral screening. Kit B, covering the broadest pathogen spectrum (including fungi/bacteria), is suitable for comprehensive respiratory pathogen screening. Kits C, D and E, are applicable for rapid detection. It is important to note that the detection efficacy of all kits decreases for low viral load samples with Ct values >35. In practical application, selection should be based on specific screening objectives, throughput requirements, and sample types.

ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work, thereby providing a theoretical basis for the improvement of education and training, incentive mechanisms, and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method, semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest, empathy, and a sense of professional responsibility, while the negative was low psychological resilience. External positive driving forces included high work support, professional identity, mutual benefits for nurses and patients, and positive patient attitudes, whereas negative driving forces comprised busy routine clinical work, lack of a reward and incentive system, and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care, intensify the publicity of palliative care and death education; intervene and guide nurses’ negative emotions, improve and implement relevant incentive systems, and standardize the job recognition and scope of responsibilities of palliative care nurses.

Work-related musculoskeletal disorders (WMSDs) represent a significant occupational health challenge among healthcare professionals globally, posing substantial threats to physical and mental well-being as well as work sustainability. Adopting preventive behaviors—including ergonomic postural adjustments, optimized work-rest scheduling, proper use of protective and assistive equipment, and regular physical activity—is essential for mitigating the risk of WMSDs. Guided by the social ecological model, the review synthesized current evidence on the determinants of WMSDs preventive behaviors across four levels: intrapersonal characteristics, work environment conditions, interpersonal support, and policy/institutional factors. The findings suggest that higher educational attainment, favorable health-related behavioral patterns, optimized ergonomic work environments, adoption of supportive collaborative systems, strong organizational support, as well as policy safeguards facilitate preventive behavior adoption. Conversely, limited prevention-related knowledge, low risk perception, insufficient physical activity, excessive workload, lack of appropriate protective equipment, inadequate ergonomic training, a prevailing culture of presenteeism, and inadequate policy implementation constitute significant barriers. Multi-dimensional intervention strategies targeting these determinants are warranted to enhance preventive behaviors, reduce the risk of WMSDs, and strengthen occupational health protection for healthcare professionals.

Renal Fanconi syndrome (FS) is a rare renal manifestation of primary Sjögren's syndrome (pSS). This study aims to analyze the clinical and prognostic characteristics of patients with pSS-associated renal FS (pSS-FS) and provide insights for clinical management. Patients diagnosed with pSS-FS via renal biopsy at Peking Union Medical College Hospital from 1993 to 2024 were enrolled. Data collected included age, sex, clinical symptoms (xerostomia, xerophthalmia, skin purpura, arthralgia, polyuria, and systemic symptoms), laboratory findings [serum immunoglobulin G (IgG) and IgM, complement (C3, C4), antinuclear antibody, anti-Sjögren's syndrome-associated antigen A antibody (SSA), anti-SSB antibody, 24-hour urinary protein quantification, tubular proteinuria, serum creatinine, serum electrolytes], treatment, and follow-up information. Systematic assessments included the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) score, pulmonary involvement (including non-infectious interstitial pneumonia, pulmonary fibrosis, pulmonary hypertension, etc.), hematological involvement (anemia, leukopenia, thrombocytopenia), etc. Efficacy evaluations encompassed improvements in immunological parameters, renal function, and tubular function. Group comparisons were performed using chi-square/Fisher's exact tests, A total of 38 patients with pSS-FS were included, with 37(97.4%) being female. The median age at pSS diagnosis was 43(37, 57) years. Xerostomia (76.3%) and xerophthalmia (71.1%) were the predominant clinical symptoms. The most common renal tubular dysfunctions were generalized aminoaciduria (96.9%), tubular proteinuria (96.0%), and hypokalemia (94.7%). The median eGFR was 52.57(32.04, 76.10)mL/(min·1.73 m2), with 60.5% (23/38) of patients having an eGFR below 60 mL/(min·1.73 m2).After six months of immunosuppressive therapy, including moderate-to-high-dose glucocorticoids, significant improvements were observed in immunological parameters (improvement rate: 69.2%), renal tubular function (89.5%), and renal function (44.4%). Following immunosuppressive treatment, the median eGFR increased from 54.95(33.06, 76.10)mL/(min·1.73 m2) to 65.56(56.24, 83.58)mL/(min·1.73 m2).Compared to patients with normal or mildly impaired baseline eGFR [≥ 60 mL/(min·1.73 m2)], those with significantly decreased baseline eGFR [< 60 mL/(min·1.73 m2)] were older (46 years This study reports the clinical characteristics of the largest single-center cohort of pSS-FS patients internationally, characterized by varying degrees of proximal renal tubular dysfunction and renal impairment. Timely initiation of immunosuppressive therapy, including glucocorticoids, is crucial, particularly for patients with significantly reduced eGFR, who may experience more substantial renal function improvement.

OBJECTIVE To study the protective effect and potential mechanism of chikusetsu saponin Ⅳ a (chsⅣ) on renal function in diabetic nephropathy (DN) model rats. METHODS DN rat model was established by high-fat diet combined with streptozotocin injection. Thirty-six model rats were randomly divided into model group (i.g. administration of normal saline, high-fat diet), chsⅣ low-dose and high-dose groups (i.g. administration of 90, 180 mg/kg chsⅣ, high-fat diet), with 12 rats in each group. Additionally, 10 normal rats were set as the control group (i.g. administration of normal saline, regular diet). From the 5th to the 12th week after streptozotocin injection, they were given intragastric administration of relevant drug or normal saline, once a day. After the last medication, the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine and urine protein as well as the levels of reduced glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissues were measured. Additionally, the insulin resistance index was calculated. Hematoxylin-eosin, periodic acid-Schiff, and Masson staining techniques were employed to examine the histopathological alterations in the renal tissue. The expressions of Notch signaling pathway-related proteins in renal tissue were detected by immunohistochemical staining and Western blot methods. RESULTS Compared with model group, the histomorphological of renal tissues in the chsⅣ low- and high-dose groups were significantly improved, with significant decreases in renal histological scores, mesangial expansion index, and glomerulosclerosis scores ( P <0.05); the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine, urine protein and homeostasis model assessment for insulin resistance, as well as MDA content, the expression levels of Notch1, Notch intracellular domain, hairy and enhancer of Split 1 and Delta-like protein 1 in renal tissue were all significantly decreased ( P <0.05). The levels of GSH and SOD in renal tissue were significantly elevated ( P <0.05). Moreover, the improvement in these indicators was significantly more pronounced in the chsⅣ high-dose group compared to the chsⅣ low-dose group ( P <0.05). CONCLUSIONS ChsⅣ can ameliorate renal pathological damage and functional impairment in DN rats. Its underlying mechanisms include restoration of glucose homeostasis and insulin sensitivity, attenuation of renal oxidative stress, and suppression of aberrant Notch signaling pathway activation.

OBJECTIVE To analyze the selection and rationales of comparators for pharmaceutical enterprises in their medical insurance access application, so as to provide a reference for promoting communication and consensus between enterprises and medical insurance authorities in this process. METHODS The application materials for drugs outside the catalogue that passed formal review published by the National Healthcare Security Administration from 2021 to 2025 were extracted, and then content analysis was used to systematically sort out relevant information of the declared drugs and comparators; the specific situations and rationales of pharmaceutical enterprises’ selection of comparators were analyzed. RESULTS A total of 1 341 declared drug documents were collected. Data analysis showed that 1 035 (77.18%) were submitted with positive comparators and 306 (22.82%) used blank comparators; 58 drugs (4.33%) took combination therapy as the reference, and 5 drugs (0.37%) referred to non-pharmacological (or non-single pharmacological) treatment regimens. Among competitive drugs declared by multiple enterprises, 50.00% of the enterprises submitted different comparators. A total of 4 basic conditions and 39 additional conditions were extracted as the rationales for selecting positive comparators. For blank comparators, 12 drug-related factors, 2 administrative factors, and 1 other factor were identified. More than 10% of the drugs did not state the rationale for comparator selection, and over 44% of drugs using blank comparators provided only one justification. CONCLUSIONS Pharmaceutical enterprises mainly select comparators based on their own interests in the medical insurance access application, and there are deficiencies in the adequacy and standardization of their selection basis and reasoning. It is recommended that enterprises follow the principled requirements of medical insurance authorities, and fully and normatively explain the reasons for selecting comparators in combination with the characteristics of their own products. Meanwhile, it is advisable to change the current open-ended statement form of selection reasons into a closed-ended answering mode, so as to highlight the priority of selection, standardize the declaration behavior of enterprises, and reduce communication divergences between the two parties.

ObjectiveTo investigate the effects of Jianpi Qinghua granules on blood glucose fluctuations in patients with newly diagnosed overweight/obese type 2 diabetes mellitus (T2DM) and Qi-Yin deficiency syndrome from the perspective of skeletal muscle mass and function, while providing new insights for the treatment of diabetes. MethodsThis study employed a randomized, double-blind, placebo-controlled design. A total of 110 newly diagnosed overweight/obese T2DM patients meeting the inclusion criteria were randomly assigned to either the traditional Chinese medicine (TCM) group (54 cases) or the control group (56 cases). Patients in the TCM group received Jianpi Qinghua Granules, while those in the control group received a placebo. Both groups underwent dietary and exercise guidance. After 12 weeks of intervention, blood glucose fluctuations were assessed using the following parameters: time in the target blood glucose range (TIR), mean daily blood glucose (MBG), standard deviation of mean daily blood glucose (SDBG), mean amplitude of glycemic excursions (MAGE), coefficient of variation of blood glucose (CV), glycated hemoglobin (HbA1c) achievement rate, fasting plasma glucose (FPG), and 2 hour postprandial glucose (2 hPG). Skeletal muscle mass was measured by dual-energy X-ray absorptiometry (DXA), while skeletal muscle function was evaluated using a handheld dynamometer for distal muscle strength and a 5-time sit-to-stand test for lower limb function. Additionally, pancreatic islet function and TCM syndrome scores were analyzed. ResultsNo significant differences were observed in baseline data between the two groups before intervention, ensuring comparability. After treatment, compared to the control group, the TCM group showed a significant increase in TIR (P<0.01). While the SDBG and CV decreased, and MBG and MAGE increased in the TCM group, these differences were not statistically significant. Notably, the TCM group exhibited significant reductions in 2 hPG (P<0.01) and HbA1c (P<0.05), though the decrease in FPG was not statistically significant. The HbA1c achievement rate in the TCM group was significantly higher than that in the control group (χ2=45.498, P<0.01). In terms of skeletal muscle mass and function, the TCM group demonstrated a significant increase in handgrip strength (P<0.01) and a significant reduction in the 5-time sit-to-stand duration (P<0.05). However, although body fat percentage increased, leading to a decrease in skeletal muscle mass and the ratio of skeletal muscle to fat, these changes were not statistically significant. For pancreatic islet function, the TCM group showed significant reductions in fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR) (P<0.01). Additionally, the TCM syndrome score in the TCM group was significantly reduced (P<0.01). ConclusionJianpi Qinghua granules may reduce blood glucose fluctuations in newly diagnosed overweight/obese T2DM patients with Qi-Yin deficiency syndrome by enhancing skeletal muscle function, improving pancreatic islet function, and ameliorating related TCM syndromes.

Chinese Journal of School Health 2026;47(4):465-469
Objective:
To explore the association between vegetable intake with glucose and lipid metabolism levels among school aged children, so as to provide scientific basis for dietary intervention on children s metabolic health.
Methods:
Based on a natural population cohort in Jiulongpo District and Fengdu County of Chongqing, 2 133 school aged children aged 6-9 years were enrolled in the baseline survey in 2014, and 2 029 children completed the follow up in 2019. Questionnaire surveys were used to collect vegetable intake, general demographic and lifestyle data. Height, weight and waist circumference were measured, and glucose and lipid metabolism indicators such as fasting blood glucose (FBG), triglyceride (TG) and total cholesterol (TC), low densith lipoprotein triglyceride (LDL-C), high densith lipoprotein triglyceride (HDL-C) were detected. Mann-Whitney U test and Kruskal-Wallis H test were used for intergroup comparisons in multivariate analysis, and mixed effects linear regression model was used to analyze the association between vegetable intake and glucose and lipid metabolism.
Results:
The levels of FBG, TG, TC, HDL-C and LDL-C at baseline and follow up were [4.09(3.90,4.48), 0.84(0.60,1.14), 3.49(3.09,3.91), 1.25(1.09,1.46), 1.69 ( 1.39 ,2.02);4.31(4.00,4.64), 0.92(0.71,1.22), 3.49(3.12,3.87), 1.36(1.16,1.57), 1.77(1.51,2.06)] mmol/L, respectively. Among these indicators, FBG, TG, HDL-C and LDL-C all increased significantly ( Z =-12.08, -7.82, -9.82, -5.37, all P < 0.01 ). The detection rate of low HDL-C levels at follow up (13.11%) was significantly lower than that at baseline (18.10%) ( χ 2=19.57, P <0.05). At baseline, there were significant differences in FBG, TC, TG, HDL-C and LDL-C among children with different vegetable intake levels ( H =68.47, 30.16, 11.02, 13.27, 44.70); at followup, only HDL-C showed significant intergroup differences ( H =13.10)(all P <0.05). Mixed effects linear regression model showed that after adjusting for confounding factors, vegetable intake was significantly negatively correlated with blood glucose levels among school aged children ( β=-0.03, 95%CI = -0.05 to -0.01, P <0.01).
Conclusion
Higher vegetable intake can independently reduce the risk of abnormal blood glucose in school aged children, which is of great significance for maintaining glucose metabolic health.

Objective To investigate the therapeutic effect of Huangkui capsules on targeted drug-related proteinuria in patients with hepatocellular carcinoma (HCC). Methods A retrospective analysis was conducted on clinical data of HCC patients with targeted drug-related proteinuria from June 2023 to December 2024 at Zhongshan Hospital, Fudan University. According to the treatment plan, patients were divided into the conventional treatment group and the Huangkui combination treatment group (Huangkui capsules combined with conventional treatment), and the clinical efficacy between the two groups was compared. The logistic regression analysis was used to identify the main factors affecting treatment efficacy. Results The Huangkui combination treatment group (n=29) showed a significantly higher overall effective rate (79.3% vs 42.3%, P=0.005), and an earlier proteinuria improvement (median time: 3 months vs 6 months, P=0.008) than the conventional treatment group (n=26) . The multivariate logistic regression analysis showed angiotensin-converting enzyme inhibitor (ACEI) or angiotensin Ⅱ receptor blocker (ARB) using (OR=0.190, 95%CI 0.045-0.808, P=0.025), targeted drug adjustment (OR=0.132, 95%CI 0.030-0.581, P=0.007), and Huangkui capsules using (OR=0.168, 95%CI 0.039-0.730, P=0.017) were protective factors for treatment efficacy of targeted drug-related proteinuria. Conclusions On the basis of conventional treatment, additive treatment with Huangkui capsules can alleviate targeted drug-related proteinuria faster and more effectively in HCC patients.

Alzheimer's disease (AD) is a common type of dementia, primarily characterized by cognitive and behavioral impairments as well as deficits in learning and memory. The progression of AD has imposed a significant economic burden on society and families. However, its exact pathogenesis has not yet been fully elucidated. Currently, available therapeutic drugs are limited and are often accompanied by serious adverse effects. Traditional Chinese medicines (TCMs) and their extracts are mostly natural products and possess advantages such as multi-pathway regulation and relatively few adverse reactions. Experimental studies have shown that TCMs exhibit great potential in the prevention and treatment of AD. For example, Huanglian Jieduang, Danggui Shaoyaosan, Kaixin San, Liuwei Dihuangwan, Buyang Huanwutang, as well as Ginseng Radix et Rhizoma, Astragali Radix, Uncariae Ramulus cum Uncis, Coptidis Rhizoma, Gardeniae Fructus, Ginkgo Folium, Salviae Miltiorrhizae Radix et Rhizoma, and Curcumae Longae Rhizoma, can reduce β-amyloid deposition, inhibit excessive Tau protein phosphorylation, restore mitochondrial function, alleviate oxidative stress, suppress neuroinflammation and apoptosis, repair synaptic function, and improve gut microbiota. This article mainly summarizes the effects of several TCMs and compound prescriptions on AD, aiming to provide a reference for subsequent TCM-based treatment of AD.
