OBJECTIVE:
To observe the efficacy and safety of eye transcutaneous electrical acupoint stimulation (Eye-TEAS) on preventing the progression of pre-myopic to myopia in children aged 6-12 years.
METHODS:
A total of 170 pre-myopic children aged 6-12 years were randomly divided into an Eye-TEAS group (85 cases, 3 cases dropped out, 2 cases were eliminated) and a placebo Eye-TEAS group (85 cases, 3 cases dropped out, 2 cases were eliminated). The Eye-TEAS group received Eye-TEAS intervention at bilateral Cuanzhu (BL2), Yuyao (EX-HN4), Sizhukong (TE23), Taiyang (EX-HN5), Sibai (ST2), and Jingming (BL1), with continuous wave at a frequency of 4 Hz and a current of 1-2 mA for 30 min per session. The placebo Eye-TEAS group received sham intervention with the same equipment and procedure, but no electrical stimulation. Both groups received intervention once every other day, at least 3 times a week, for a duration of 20 weeks. After intervention and during the 28-week follow-up period after the intervention completion, the changes in axial length (AL), spherical equivalent refraction (SER), and the incidence of myopia were compared between the two groups. Adherence and safety during the intervention period were also evaluated.
RESULTS:
Compared before intervention, both groups showed an increase in AL after the intervention and during the follow-up (P<0.01). The AL during follow-up was higher than that after the intervention in the two groups (P<0.01). The Eye-TEAS group exhibited a smaller change in AL than the placebo Eye-TEAS group after the intervention and during follow-up (P<0.01, P<0.05). Compared before intervention, both groups showed a decrease in SER after the intervention and during follow-up (P<0.01). The SER during follow-up was lower than that after the intervention in the two groups (P<0.01). The Eye-TEAS group had a higher SER than the placebo Eye-TEAS group after the intervention (P<0.05). The Eye-TEAS group exhibited a smaller change in SER than the placebo Eye-TEAS group after the intervention and during follow-up (P<0.01). The incidence of myopia in the Eye-TEAS group was lower than that in the placebo group during follow-up (20.0% [14/70] vs 34.7% [25/72], P<0.05). Both groups had good adherence, with no adverse events related to the intervention.
CONCLUSION
Eye-TEAS can delay the progression of pre-myopic to myopia in children, and has a high safety profile.

OBJECTIVE:
To reveal the molecular basis of knee osteoarthritis (KOA) with Yang deficiency and blood stasis syndrome by analyzing the gene expression profiles in synovial fluid and blood of KOA patients with this syndrome.
METHODS:
A total of 80 KOA patients were recruited from October 2022 to June 2024, including 40 cases in the non-Yang deficiency and blood stasis group (27 males and 13 females), with an average age of (61.75±3.45) years old;and 40 cases in the Yang deficiency and blood stasis group (22 males and 18 females), with an average age of (62.00±2.76) years old. The levels of body mass index (BMI), high-density lipoprotein (HDL), low-density lipoprotein (LDL), fibrinogen, total cholesterol, and D-dimer were recorded and summarized. Blood and synovial fluid samples from patients were collected for gene expression profile microarray sequencing, and then PCR and immunohistochemistry were used for clinical verification on the patients' synovial fluid and cartilage samples.
RESULTS:
Logistic regression analysis showed that compared with KOA patients with non-Yang deficiency and blood stasis syndrome, those with Yang deficiency and blood stasis syndrome had increased BMI, LDL, fibrinogen, total cholesterol, and D-dimer, and decreased HDL, with a clear correlation between the two groups. There were 562 differential genes in the blood, among which 322 were up-regulated and 240 were down-regulated;755 differential genes were found in the synovial fluid, with 350 up-regulated and 405 down-regulated. KEGG signaling pathway analysis of synovial fluid revealed changes in lipid metabolism-related pathways, including cholesterol metabolism, fatty acid metabolism, and PPARG signaling pathway. Analysis of the involved differential genes identified 6 genes in synovial fluid that were closely related to lipid metabolism, namely LRP1, LPL, ACOT6, TM6SF2, DGKK, and PPARG. Subsequently, PCR and immunohistochemical verification were performed using synovial fluid and cartilage samples, and the results were consistent with those of microarray sequencing.
CONCLUSION
This study explores the clinical and genomic correlation between traditional Chinese medicine syndromes and knee osteoarthritis from the perspective of lipid metabolism, and proves that abnormal lipid metabolism is closely related to KOA with Yang deficiency and blood stasis syndrome from both clinical and basic aspects.

OBJECTIVE
To establish a ultra-high-performance liquid chromatography-mass spectrum/mass spectrum(UPLC-MS/MS) method for the determination of anlotinib in human plasma and assessment of clinical application.
METHODS
Zanubrutinib was used as internal standard and the extraction process was performed through protein precipitation method using acetonitrile, followed by separation on an Ultimate XB-C18(100 mm×2.1 mm, 3.0 μm) column using acetonitrile and 10 mmol·L−1 ammonium acetate-0.1% formic acid step-elution gradient. The flow rate was 0.6 mL·min−1 and injection volume was 5 μL. The mass analysis was performed by positive ion electrospray ionization in multiple-reaction monitoring mode, and the mass spectrometer was set at m/z 408.1→339.1 for anlotinib and m/z 472.2→290.1 for internal standard, respectively. The specificity, standard curve and lower limit of quantification, precision and recovery, matrix effect and stability of the method and clinical application were investigated.
RESULTS
The method was validated over the concentration range of 1.0−100.0 ng·mL−1, with R2=0.998 4. The precision RSD was<9%, the recovery and matrix effect were 104.81%−107.32% and 102.54%−105.26%, respectively, and this method had good stability and was not affected by matrix effect. The method had been used for determined 52 advanced non-small cell lung cancer patients treated with anlotinib. The trough plasma concentration (Ctrough) was measured on day 43 after initiation of anlotinib treatment. Anlotinib Ctrough were higher than lower limit of quantitation (1.0 ng·mL−1) from 52 patients. The plasma concentration of anlotinib Ctrough was (11.38±4.29)ng·mL−1 with 37.66% coefficients of variation, which were shown large inter-patient variability.
CONCLUSION
This method is high sensitivity, specificity and accurate, and suitable for determination of anlotinib in human plasma.

Energy metabolism is fundamental for life.It encompasses the utilization of carbohydrates,lipids,and proteins for internal processes,while aberrant energy metabolism is implicated in many diseases.In the present study,using three-dimensional(3D)printing from polycarbonate via fused deposition modeling,we propose a multi-nuclear radiofrequency(RF)coil design with integrated 1H birdcage and interchangeable X-nuclei(2H,13C,23Na,and 31P)single-loop coils for magnetic resonance imaging(MRI)/magnetic resonance spectroscopy(MRS).The single-loop coil for each nucleus attaches to an arc bracket that slides unrestrictedly along the birdcage coil inner surface,enabling convenient switching among various nuclei and animal handling.Compared to a commercial 1H birdcage coil,the proposed 1H birdcage coil exhibited superior signal-excitation homogeneity and imaging signal-to-noise ratio(SNR).For X-nuclei study,prominent peaks in spectroscopy for phantom solutions showed excellent SNR,and the static and dynamic peaks of in vivo spectroscopy validated the efficacy of the coil design in structural imaging and energy metabolism detection simultaneously.

Objective:To explore the diagnostic value of laboratory examination in bronchoalveolar lavage fluid(BALF) for interstitial lung disease (ILD) and its application value in assessing the degree of fibrosis in the disease.Methods:Retrospective analysis. The clinical data of ILD patients treated in Shanghai First People′s Hospital from January 1, 2021 to December 31, 2023[104 cases, male︰female=48︰56, (62.79±1.24) years] were collected. According to the imaging scores, they were divided into a mild fibrosis ILD group [53 cases, male︰female=26︰27, (61.32±1.71) years] and a moderate to severe ILD fibrosis group [51 cases, male︰female=22︰29, (64.31±1.88) years]. Patients with community-acquired pneumonia without fibrotic lesions by HRCTduring the same period were selected as the control group [49 cases, male︰female=25︰24, (65.37±1.65)years]. The clinical information of all study subjects, as well as BALF lymphocyte subset analysis, cytokine and cytology count detection results were collected. Furthermore, the Kruskal-Wallis H test was used to screen the differential indexes, and the receiver operating characteristic (ROC) curve was used to evaluate the differential indexes to assess the degree of ILD pulmonary fibrosis.Results:Compared with the non-fibrotic pneumonia group, IL-6, IL-8, CD4+CD45RO+cells and macrophages (M%) were significantly upregulated in the mild fibrosis ILD group (P<0.05), and significantly higher in the moderate to severe fibrosis ILD group ( P<0.05). Compared with the non-fibrotic pneumonia group, IL-1β and white blood cell (WBC) count were significantly upregulated only in the moderate to severe fibrotic ILD group ( P<0.05). The correction model was constructed by stepwise logistic regression analysis, and the differential indexes were combined, and the proportion of IL-1β+IL-6+IL-8+CD4+CD45RO+cells+macrophages was finally screened as the optimal combined diagnostic mode, with an area under the curve of 0.925, sensitivity of 92.3%, and specificity of 80.0%. Conclusion:Compared with the non-fibrotic pneumonia group, BALF-derived IL-1β, IL-6, IL-8, CD4+CD45RO+cells, WBC count and M% can be used as potential biomarkers to assess the degree of fibrosis, and the combination of IL-1β+IL-6+IL-8+CD4+CD45RO+cells+macrophages has a better diagnostic efficacy for moderate to severe fibrotic ILD.
