ObjectiveTo observe the effect of Qishao capsules on renal injury in db/db mice with diabetic kidney disease （DKD），and explore its mechanism of protecting the kidney by inhibiting podocyte apoptosis. Methodsdb/m mice （7 mice） were used as the normal group，and db/db mice （35 mice） were randomly divided into a model group，a dapagliflozin group （0.001 g·kg^-1·d^-1），and low-，medium-，and high-dose groups of Qishao capsules （0.341 3，0.682 5，and 1.365 g·kg^-1·d^-1，respectively）. Drug intervention lasted for 8 consecutive weeks. After sampling，the serum renal function indicators ［creatinine（SCr），and urea nitrogen（BUN）］，fasting blood glucose （FBG），24 h urinary protein quantification （24 h-UTP）， and other indicators of the mice were measured. The pathological tissue morphology of the kidney was observed by periodic acid-silver methenamine （PASM） and Masson's trichrome （Masson） staining. Immunohistochemical detection of cysteine-dependent aspartate-specific protease （Caspase）-3 and B-cell lymphoma 2 （Bcl-2） was performed. Western blot was used to detect the protein expression of Caspase-8，Caspase-7，Caspase-3， and other molecules. Terminal deoxynucleotidyl transferase dUTP nick End labeling （TUNEL） staining was used to observe apoptosis in renal tissue. Immunofluorescence staining of Wilms tumor suppressor gene-1 （WT-1） was used to observe podocyte injury. Real-time polymerase chain reaction （Real-time PCR） was employed to detect Caspase-8 and Caspase-3 mRNA expression in the kidneys of experimental mice. Data analysis was conducted using statistical software GraphPad Prism 10. ResultsCompared with the normal group，the model group showed significantly increased 24 h-UTP，SCr，BUN，and FBG （P<0.01）. Additionally， PASM staining of renal tissue showed increased glycogen deposition，glomerular hypertrophy，and thickening of the basement membrane. Masson staining showed collagen fiber proliferation in renal tissue. Transmission electron microscopy showed thickening of the renal tissue basement membrane and fusion or loss of foot processes in the model group. The immunohistochemical results showed that Caspase-3 in the kidneys of the mice in the model group significantly increased （P<0.01），while the Bcl-2 protein expression level decreased significantly （P<0.01）. The number of TUNEL positive cells in renal tissue significantly increased （P<0.01）. The positive expression of WT-1 in podocytes was significantly reduced （P<0.01）. Western blot analysis showed significant upregulation of Caspase-8，Caspase-7，and Caspase-3 protein expression in renal tissue （P<0.01）. The mRNA expression levels of Caspase-8 and Caspase-3 in the kidneys increased significantly （P<0.01）. Compared with the model group，the Qishao capsules groups can significantly reduce the levels of 24 h-UTP，SCr，BUN，and FBG （P<0.01）. The pathological damage of renal tissue and podocyte injury were improved to some extent. Immunohistochemistry in the kidney showed a significant decrease in Caspase-3 （P<0.01） and a significant increase in Bcl-2 protein expression level （P<0.01）. Additionally， there were a significant decrease in the number of TUNEL positive cells in renal tissue （P<0.01），a significant increase in WT-1 positive expression in podocytes （P<0.01），marked downregulation of Caspase-8，Caspase-7，and Caspase-3 protein expression in renal tissue （P<0.05，P<0.01），and a significant decrease in Caspase-8 and Caspase-3 mRNA expression levels （P<0.01）. ConclusionQishao capsules can inhibit podocyte apoptosis by regulating the expression of Caspase-8，Caspase-7， and Caspase-3，thereby improving the diabetic renal injury in db/db mice.

AIM:To evaluate the accuracy of a portable non-contact tonometer(PNCT)compared with a traditional non-contact tonometer(NCT)in measuring intraocular pressure(IOP)at different levels.METHODS:Patients who presented to Ningbo Eye Hospital between January 2025 and January 2026 were retrospectively included. All patients underwent measurements using PNCT, NCT, and Goldmann applanation tonometry(GAT). Based on the GAT measurements, the patients were categorized into a low IOP group(IOP≤16 mmHg), a moderate IOP group(16 mmHg0.05). Spearman correlation analysis revealed that the IOP values measured by both PNCT and NCT were positively correlated with those measured by GAT(rs=0.86 and 0.84, respectively, P<0.05). Intraclass correlation coefficient(ICC)analysis demonstrated an ICC of 0.89 between PNCT and GAT(P<0.05), and 0.88 between NCT and GAT(P<0.05), with an overall ICC of 0.88 among the three instruments(P<0.05). Bland-Altman analysis indicated a mean bias of 0.1 mmHg [95% limits of agreement(LoA): -7.3 to 7.6 mmHg] between PNCT and GAT, and a mean bias of 0.1 mmHg(95%LoA: -8.4 to 8.6 mmHg)between NCT and GAT. Based on the GAT measurements, the eyes were categorized into a low IOP group(60 eyes, 32.6%, IOP≤16 mmHg), a moderate IOP group(63 eyes, 34.2%, 16 mmHg0.05), whereas the difference between NCT and GAT showed a positive correlation with CCT(rs=0.23, P<0.05).CONCLUSION:The IOP measurements obtained by PNCT, NCT, and GAT demonstrated strong correlation and good agreement, with PNCT being less influenced by CCT. However, as IOP levels increased, the measurement errors of both PNCT and NCT also increased. Therefore, PNCT and NCT readings should only serve as references and cannot replace GAT.

Acute lung injury （ALI） is a critical respiratory emergency caused by various non-cardiogenic factors， including severe pulmonary and extrapulmonary infections， lung contusion， and sepsis. Its pathological features are centered on alveolar-capillary barrier dysfunction， uncontrolled inflammatory responses， and impaired alveolar fluid clearance， manifesting as refractory hypoxemia and respiratory distress， with a poor clinical prognosis. Modern studies have revealed that mitochondrial dysfunction and glucose metabolic reprogramming in macrophages， characterized by hyperactivated glycolysis， drive pro-inflammatory polarization and represent a key mechanism leading to excessive inflammatory responses and disease progression in ALI. Therefore， targeting macrophage glycolysis may be a potential therapeutic strategy for ALI. The Plain Questions： Special Discussion on Channels and Vessels in Huangdi's Internal Classic states that "The spleen disseminates essence upward to the lungs". When the spleen fails in transport and transformation， the distribution of refined nutrients becomes disordered， resulting in the endogenous generation of turbid pathogens that obstruct the pulmonary collaterals， causing failure of lung dispersion and descent and leading to dyspneic reversal. This forms the dynamic pathological pattern of ''deficiency in the root with excess in the manifestation''， thereby proposing the core pathogenesis of ALI as ''spleen deficiency with transport dysfunction and turbid pathogens obstructing the lungs''. This process is intrinsically associated with the inflammatory cascade triggered by disordered macrophage glucose metabolism. Taking the theory of ''spleen failing to disperse essence'' as the entry point， the present study systematically elucidates the progressive pathological mechanism of "energy metabolism disorder-cytokine storm'' in ALI from the perspectives of the ''spleen deficiency-turbid obstruction'' pathogenesis and macrophage glycolysis-pro-inflammatory polarization. In addition， we summarize Chinese medicine compound formulas and monomeric components that ''restore spleen transport and eliminate turbid pathogens''， and explore their potential mechanisms in the treatment of ALI by regulating macrophage metabolic phenotypes to improve the state of ''spleen failing to disperse essence''. This provides a molecular basis for elucidating the ''spleen-lung'' energy metabolism dialogue， deepens understanding of the multi-target regulatory mechanisms of herbal prescriptions， and promotes the deep integration of classical theory with modern medicine.

AIM:To observe the therapeutic efficacy of 0.05% cyclosporine combined with olopatadine hydrochlorideeye drops in the treatment of moderate-to-severe pediatric vernal keratoconjunctivitis.METHODS:A prospective randomized controlled study was conducted. Patients with moderate-to-severe pediatric vernal keratoconjunctivitis admitted to the hospital from January to December 2023 were collected and divided into two groups according to the random number table method: the observation group was treated with olopatadine combined with 0.05% cyclosporine hydrochloride eye drops [1 drop per time of 0.05% cyclosporine eye drops(II), four times a day; 1 drop per time of olopatadine hydrochloric eye drops, twice a day]; the control group was treated with sodium hyaluronate combined with olopatadine hydrochloride eye drops(1 drop per time of sodium hyaluronate eye drops, four times a day; 1 drop per time of olopatadine hydrochloric eye drops, twice a day; ). The treatment lasted for 12 wk. The changes in symptom and sign scores of the two groups before treatment, and at 4, 8, and 12 wk after treatment were compared.RESULTS:Totally 42 children(84 eyes)with moderate-to-severe vernal keratoconjunctivitis were enrolled. All patients returned for follow-up visits on time, with no lossto follow-up. The observation group consisted of 21 patients(42 eyes), with 15 males and 6 females, and the average age was 9.00±3.02 y. The control group consisted of 21 patients(42 eyes), with 18 males and 3 females, and the average age was 9.38±3.28 y(all P>0.05). At 4, 8, and 12 wk after treatment, the ocular symptom and sign scores of both groups decreased compared to those before treatment(all P<0.05), and the decrease in the observation group was more significant than that in the control group(P<0.05). During the treatment period, one patient in the observation group experienced a transient mild ocular irritation at the beginning of medication, which was not treated specially and relieved spontaneously after 3 d. No severe adverse reactions such as elevated intraocular pressure or corneal infection occurred in either group during the treatment period.CONCLUSION:The combination of 0.05% cyclosporine and olopatadine hydrochlorideeye drops significantly alleviates the clinical symptoms and signs of moderate-to-severe vernal keratoconjunctivitis, showing favorable safety and efficacy in the treatment of moderate-to-severe pediatric vernal keratoconjunctivitis.

Objective:To investigate the efficacy and safety of endovascular treatment (EVT) in young patients with symptomatic intracranial atherosclerotic stenosis (sICAS).Methods:Young patients with sICAS admitted to the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University, Medical School from January 2020 to July 2024 were included retrospectively. According to the therapeutic modalities, they were divided into a best medical treatment (BMT) group and an EVT group. The efficacy outcome was any stroke recurrence or death within 30 days and 1 year. The safety outcome was symptomatic intracranial hemorrhage (sICH) within 30 days and restenosis within 1 year.Results:A total of 113 patients were enrolled, including 85 males (75.2%), with a median age of 43 (interquartile range, 37-48) years; 44 patients (38.9%) received EVT, and 69 (61.1%) received BMT. Among the 44 patients who underwent EVT, 8 (18.2%) underwent balloon angioplasty and 36 (81.8%) underwent stenting. There was no significant difference in the incidence of stroke recurrence or death within 30 days (2.9% vs. 2.3%) and sICH incidence (0% vs. 2.3%) between the BMT group and the EVT group. However, the 1-year stroke recurrence or death rate in the EVT group was significantly lower than that in the BMT group (18.8% vs. 4.5%; P=0.029). Cox proportional hazards regression analysis showed that EVT was independently associated with a lower incidence of stroke recurrence or death within 1 year (hazard ratio 0.225, 95% confidence interval 0.051-0.996; P<0.05). The median age of the balloon angioplasty group was significantly lower than that of the stenting group (33.5 years vs. 46 years; P=0.007), while there were no significant differences in other demographic and baseline data. There was no significant difference in all efficacy and safety outcome between the balloon angioplasty group and the stenting group. Conclusions:For young patients with sICAS who have an unsatisfactory response to drug treatment, EVT can reduce the risk of stroke recurrence or death within 1 year without increasing the risk of sICH. The safety and efficacy of balloon angioplasty and stenting are similar.

Objective:To investigate the current status of application of stereotactic body radiation therapy (SBRT) in China, aiming to provide reference for promoting the development of this technology.Methods:From January to March 2024, a questionnaire was designed and distributed online, targeting member units of the Professional Committee of Stereotactic Radiosurgery Treatment, which covers 175 radiotherapy units in 30 provinces and regions nationwide. The survey focused on the current application of SBRT technology and its utilization in the treatment of early-stage non-small cell lung cancer (NSCLC). A statistical description of the survey results was presented.Results:Of 175 questionnaires distributed, a total of 130 valid responses were collected, with an effective response rate of 74.3%. A total of 81.5% (106/130) of the units had implemented SBRT technology, and 99.1% of the respondents believed it was necessary to further promote SBRT technology, yet the actual training rate was only 67.0%. SBRT equipment configuration: there were a total of 267 SBRT equipment, featuring a diverse range of types, with traditional linear accelerators as the mainstays, accounting for 76.0% ( n=203), followed by 12.0% ( n=32) for TOMO, 6.4% ( n=17) for Cyber knife, 3.7% ( n=10) for Gamma knife, and proton/heavy ion equipment at 1.5% ( n=4), respectively. The percentage of units with multi-leaf collimator leaf widths ≤0.5 cm was 93.4% (99/106). The application of SBRT: the first radiotherapy unit commenced SBRT in 2000, and this technology entered a period of rapid growth after 2015, sustaining a steady increase over the past decade; SBRT technology was mainly applied in the brain, lung, liver, bone, adrenal gland, and kidney, with application rates of 97.2%, 94.3%, 86.8%, 71.7%, 56.6%, and 27.4%, respectively, while the application rates for the pancreas, metastatic lymph nodes, and other parts were less than 5%. Current status of SBRT technology application in early-stage NSCLC: 90.6% (96/106) of units had implemented SBRT; pre-treatment multi-disciplinary diagnosis and treatment accounted for 77% (74/96); the proportion of application units for peripheral and central type lung cancer lesions both exceeded 57.3%, whereas the application rate for ultra-central type and lesions > 5 cm lung cancer was less than 30%; there was significant variability in the selection of reference guidelines, dose fractionation patterns, and the concept of central type among units. Conclusions:The development of SBRT technology in China is in a period of steady growth, but several issues such as low training rate and lack of standardization still exist. The survey results provide important reference for clinical training and promotion of SBRT technology in China.

Systemic scleroderma (SSc) is a fibrotic disease involving the skin and a variety of internal organs, which is currently thought to be mainly caused by abnormal activation of fibroblasts and excessive secretion of extracellular matrix. Growing evidence has shown signaling cascades associated with SSc fibrosis, including transforming growth factor-β/Smads, Notch, Wnt/β-catenin, rat sarcoma/extracellular regulated protein kinases, etc. MicroRNAs participate in the post-transcriptional regulation of different target genes and control the cell state, determining the changes in transcriptomes and proteomes caused by various cellular signaling cascades. This review summarizes recent research progress in the regulatory role of microRNAs in SSc fibrosis-related signaling pathways and potential therapeutic targets.
