Objective To systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing evidence-based medical evidence for TCM intervention in pulmonary nodules. Methods Computer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. Results A total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. Conclusion TCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.

ObjectiveThis paper aims to investigate the intervention effect and molecular mechanism of Gancao Fuzitang （GCFZT） in knee osteoarthritis （KOA）. MethodsNetwork pharmacology was employed to predict the key targets and signaling pathways of GCFZT. Fifty SD rats were randomly divided into a sham group， a model group （KOA）， a low-dose GCFZT group （GCFZT-L， 2.8 g·kg^-1）， a high-dose GCFZT group （GCFZT-H， 5.6 g·kg^-1）， and a positive drug celecoxib group （Celecoxib， 20 mg·kg^-1）， with 10 rats in each group. The rats in the sham group and the model group were given an equal volume of distilled water. Except for the sham group， the other four groups underwent anterior cruciate ligament transection to establish the KOA rat model. After successful modeling， the rats in each group received intragastric administration once a day for eight consecutive weeks. The structural changes of cartilage and subchondral bone were assessed via micro-computed tomography （micro-CT） and histological staining. The levels of inflammatory factors in the serum， such as interleukin-1β （IL-1β）， IL-6， and tumor necrosis factor-α （TNF-α） were measured using an enzyme linked immunosorbent assay （ELISA） kit. Real-time quantitative polymerase chain reaction （Real-time PCR）， Western blot， and immunohistochemistry were used to detect changes in the expression of autophagy-related proteins such as microtubule-associated protein 1 light chain 3B （LC3B）， selective autophagy junction protein 62 （p62）， and autophagy key molecule yeast Atg6 homolog （Beclin-1） in articular cartilage， as well as key molecules of the phosphatidylinositol 3 kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. ResultsNetwork pharmacology analysis suggests that GCFZT may exert anti-osteoarthritic effects through regulating the PI3K/Akt/mTOR pathway. In vivo experiment shows that GCFZT can significantly improve cartilage degeneration and attenuate subchondral bone destruction in KOA rats. Detection results of inflammatory factors in the serum reveal that， compared with those in the sham group， the levels of IL-6， IL-1β， and TNF-α in the serum of rats in the KOA group are significantly increased （P<0.05）. Compared with those in the KOA group， the levels of these three inflammatory factors in the GCFZT-L， GCFZT-H， and Celecoxib groups were significantly decreased （P<0.05）. However， there was no statistically significant difference in these three inflammatory factor levels between the GCFZT-H group and the celecoxib group. These findings suggest that GCFZT can effectively inhibit the systemic inflammatory response in KOA rats. Mechanism research indicates that GCFZT inhibits activation of the PI3K/Akt/mTOR pathway， thereby enhancing autophagic activity and improving chondrocyte function and matrix degeneration. ConclusionGCFZT improves cartilage and subchondral bone damage in KOA rats by inhibiting the PI3K/Akt/mTOR signaling pathway and promoting autophagy. These findings provide theoretical evidence for the application of GCFZT in the prevention and treatment of osteoarthritis.

Objective To explore the therapeutic effect of cornuside on diabetic retinopathy(DR)in rats and ana-lyze the acting mechanism of the reactive oxygen species(ROS)/thioredoxin interacting protein(TXNIP)/NOD-like recep-tor thermal protein domain associated protein 3(NLRP3)signaling pathway in this process.Methods A total of 56 suc-cessfully modeled DR rats were randomly divided into the model group,the cornuside 20 mg·kg-1 group,the cornuside 40 mg·kg-1 group,the calcium dobesilate 5.8 mg·kg-1 group,with 14 rats in each group;while,meanwhile another 14 healthy rats were selected as the control group.After the corresponding intervention of rats in each group,retinal tissue in-flammation,oxidative stress indicators,fasting blood glucose(FBG),and angiogenic factor levels were detected by the en-zyme-linked immunosorbent assay(ELISA).The hematoxylin-eosin(HE)staining and terminal deoxynucleotidyl transfer-ase dUTP nick end labeling(TUNEL)staining were used to observe retinal histopathology and retinal cell apoptosis,re-spectively.The mRNA expression of ROS,TXNIP,and NLRP3 in the retinal tissue was detected by the quantitative fluores-cence polymerase chain reaction(PCR).The apoptosis of retinal cells and the protein expression of the ROS/TXNIP/NL-RP3 signaling pathway were detected by Western blotting.Results Compared with the control group,the model group showed disordered arrangement of retinal cells and a significant decrease in the cell number,accompanied by nuclear con-densation and edema;interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),malondialdehyde(MDA),FBG,angiopoie-tin-1(Ang-1),vascular endothelial growth factor(VEGF),retinal cell apoptosis rate,ROS,and the mRNA and protein ex-pression levels of TXNIP and NLRP3 increased significantly,while superoxide dismutase(SOD)and B cell lymphoma-2(Bcl-2)protein expression levels decreased significantly(all P＜0.05).Compared with the model group,the arrangement of retinal cells in the cornuside 20 mg·kg-1 group,the cornuside 40 mg·kg-1 group,and the calcium dobesilate 5.8 mg·kg-1 group gradually became normal,the number of retinal cells increased,and the nuclear condensation and edema were relieved;IL-6,TNF-α,MDA,FBG,Ang-1,VEGF,retinal cell apoptosis rate,ROS,and the mRNA and protein expression level of TXNIP and NLRP3 decreased significantly,while the protein expression level of SOD and Bcl-2 increased signifi-cantly(all P＜0.05).In the intergroup comparison of the pathological damage of retinal tissue and the improvement degree of the above quantitative indexes in DR rats,the cornuside 40 mg·kg-1group was superior to the cornusin 20 mg·kg-1 group(all P＜0.05);the calcium dobesilate 5.8 mg·kg-1 group was superior to the cornusin 20 mg·kg-1 group,but infe-rior to the cornuside 40 mg·kg-1 group(all P＜0.05).Conclusion Cornuside can mitigate retinal inflammation,oxi-dative stress,and pathological damage in DR rats and inhibit blood glucose,retinal angiogenesis,and cell apoptosis.The acting mechanism of cornuside may be related to the inhibition of the ROS/TXNIP/NLRP3 signaling pathway.

The enterprising subscore of the EMQ in the ICSMT group (35.0 (32.0, 37.0)) was significantly higher than that in the control group (31.0 (29.0, 34.0)) ( P<0.001). Furthermore, the differences of enterprising and magnanimous subscores between the two groups before and after intervention in the ICSMT group (2.0 (1.0, 4.0), 1.0 (-1.0, 2.0))were significantly higher than those in the control group (-1.0 (-1.0, 0), -1.0 (-1.2, 0)) (both P<0.05). Systolic and diastolic blood pressure values in the ICSMT group (130 (126, 134) mmHg, 85 (80, 88) mmHg)were significantly lower than those in the control group (145 (138, 152) mmHg, 93 (88, 99) mmHg)(1 mmHg=0.133 kPa) after 4 weeks of intervention(both P<0.05). After 4 weeks of intervention, the level of BUN in the ICSMT group (5.5 (3.7, 8.4) mmol/L) was significantly lower than that in the control group (9.1 (6.8, 11.4) mmol/L), while the level of Hb and ALB in the ICSMT group ((115.0±10.0)g/L, (38.3±3.2)g/L)were significantly higher than those in the control group ((104.0±12.0)g/L, (37.1±2.9)g/L) (all P<0.05). After 4 weeks of intervention, the physical functioning, role-physical, general health, vitality, social functioning, role-emotional, and mental health subscores of SF-36 in ICSMT group were all significantly higher than those in the control group (all P<0.05). After 4 weeks of intervention, the score of ADL in the ICSMT group (15.42±1.58)was significantly lower than that in the control group (16.78±2.06) ( t=-4.08, P<0.05). At the 2-week post-intervention and the 4-week post-intervention, the severity of illness (SI) and global improvement (GI) in the ICSMT group were significantly lower than those in the control group, while the efficacy index (EI) in the ICSMT group was significantly higher than that in the control group (all P<0.05). Conclusion:ICSMT can effectively promote the physical, psychological, and social functional rehabilitation of end-stage renal disease patients undergoing MHD, significantly improving their quality of life.

Objective:To evaluate the diagnostic value of native T1 mapping in differentiating Oxford classification (MEST-C) scores in patients with IgA nephropathy.Methods:In this prospective study, patients who underwent both T1 mapping and renal biopsy at the First Medical Center of the Chinese PLA General Hospital between April 2023 and October 2024 were consecutively enrolled. Two radiologists, blinded to clinical and pathological information, measured renal T1 mapping parameters, including cortical T1 (cT1), medullary T1 (mT1), the corticomedullary difference (ΔT1), and the corticomedullary ratio (T1 ratio). Clinical and renal biopsy data based on the Oxford classification from patients with IgA nephropathy were collected. The Oxford classification includes five indicators: Mesangial hypercellularity (M), Endocapillary hypercellularity (E), Segmental glomerulosclerosis or adhesion (S), Tubular atrophy/interstitial fibrosis (T), and Cellular or fibrocellular crescents (C). Spearman correlation analysis was applied to evaluate the associations between MEST-C scores and T1 parameters. The diagnostic performance of T1 parameters for discriminating among scores of the Oxford classification was analyzed using the receiver operating characteristic (ROC) curve.Results:A total of 124 patients with IgA nephropathy were included in this study [66 males, 58 females; age 19-70 years, 39 (30, 51) years]. Except for the E indicator, M, S, T, and C were significantly correlated with renal T1 values ( ρ=0.177-0.414, all P<0.05). cT1 showed the best diagnostic efficacy for the S score, with an area under the curve (AUC) of 0.798, a sensitivity of 68.7%, and a specificity of 88.0%. The best T1 parameter for differentiating the T score was the T1 ratio, with an AUC of 0.687, a sensitivity of 57.9%, and a specificity of 79.1%. Conclusion:Native T1 mapping can be used for the non-invasive assessment of the S and T scores in the Oxford classification of patients with IgA nephropathy.
