Objective:To observe the efficacy and safety of adrenocorticotropic hormone (ACTH) therapy in children with steroid dependent nephrotic syndrome (SDNS)/frequently relapsed nephrotic syndrome (FRNS).Methods:The clinical data of children with SDNS/FRNS who received treatment with prednisone acetate tablets were retrospectively collected from June 2019 to June 2023 in the Nephrology Department of Xi′an Children′s Hospital. The children were divided into glucocorticoid+ACTH group and glucocorticoid group, according to whether ACTH was used or not. The differences in cortisol, total cholesterol and 24 hour urinary protein quantity between 2 groups of children at baseline and follow-up endpoints were compared, and the effectiveness (the proportion of no recurrence and discontinuation of glucocorticoid) and occurrence of adverse reactions were evaluated.Results:A total of 39 patients with SDNS/FRNS were included in this study, with 21 cases in the glucocorticoid+ACTH group and 18 cases in the glucocorticoid group. Among the 39 children, there were 33 cases of SDNS and 6 cases of FRNS, respectively. The proportion of baseline low cortisol levels was 76.9% (30/39). The proportion of cortisol levels returning to normal after ACTH treatment in the glucocorticoid+ACTH group was 76.2% (16/21). The baseline and follow-up endpoint for cortisol levels in the glucocorticoid+ACTH group were 28.0(19.8, 51.5) μg/L and 79.9(58.9, 113.0) μg/L, respectively. The baseline and follow-up endpoint for cortisol levels in the glucocorticoid group were 21.0(15.8, 37.4) μg/L and 25.3(18.2, 51.4) μg/L, respectively. In the 2 groups of cortisol levels, there was statistically significant difference in the interaction effect between time and group ( Wald χ2=11.595, P=0.001), there was a statistically significant difference at the follow-up endpoint between the 2 groups ( Wald χ2=19.462, P<0.001), and the difference was statistically significant in the time effect of the glucocorticoid+ACTH group ( Wald χ2=21.100, P<0.001). The baseline and follow-up endpoint for total cholesterol in the glucocorticoid+ACTH group were 4.95(4.23, 5.26) mmol/L and 4.38(4.04, 5.24) mmol/L, respectively. The baseline and follow-up endpoint for total cholesterol in the glucocorticoid group were 4.80 (4.17, 5.28) mmol/L and 5.74 (5.04, 6.88) mmol/L, respectively. In the 2 groups of total cholesterol, there was statistically significant difference in the interaction effect between time and group ( Wald χ 2=9.842, P=0.002), there was statistically significant difference at the follow-up endpoint between the 2 groups ( Wald χ 2=12.187, P<0.001), the difference was statistically significant between the 2 groups in the time effect at baseline and the follow-up endpoint (glucocorticoid+ACTH group: Wald χ 2=6.488, glucocorticoid group: Wald χ2=7.112; all P<0.05). The baseline and follow-up endpoint for 24 hour urinary protein quantity in the glucocorticoid+ACTH group were 115 (105, 128) mg/d and 121 (113, 128) mg/d, respectively. The baseline and follow-up endpoint for 24 hour urinary protein quantity in the glucocorticoid group were 118 (113, 125) mg/d and 138 (119, 2 100) mg/d, respectively. In the 2 groups of 24 hour urinary protein quantity, there was statistically significant difference in the interaction effect between time and group ( Wald χ2=7.743, P=0.005), there was statistically significant difference at the follow-up endpoint between the 2 groups ( Wald χ2=7.779, P=0.005), and the difference was statistically significant in the time effect of the glucocorticoid group ( Wald χ2=13.331, P<0.001). The proportion of no recurrence (17/21) and discontinuation of oral glucocorticoid (16/21) in the glucocorticoid+ACTH group were higher than those in the glucocorticoid group (the proportion were both 6/18), and the differences between the 2 groups were statistically significant (the chi square values were 9.084 and 7.240, respectively; all P<0.01). No adverse reactions occurred in the glucocorticoid group. The incidence of adverse reactions in the glucocorticoid+ACTH group was 14.3% (3/21), of which 2 cases developed generalized urticaria and 1 case developed hypertension. Conclusions:ACTH has a good efficacy and safety in children with SDNS/FRNS. The results of this study need to be further validated by increasing the sample size and conducting multicenter studies.

BACKGROUND:
There is a gap in understanding the effects of different acupoints and treatment methods (acupuncture and moxibustion) on microcirculatory changes in the lumbar region.
OBJECTIVE:
This study aimed to assess the thermal effects of acupuncture at Weizhong (BL40), with acupuncture at Chize (LU5) and moxibustion at both acupoints as control interventions.
DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS:
In this randomized controlled trial, 140 healthy participants were equally divided into four groups: acupuncture at BL40 (Acu-BL40), acupuncture at LU5 (Acu-LU5), moxibustion at BL40 (Mox-BL40) and moxibustion at LU5 (Mox-LU5). Participants underwent a 30-minute session of their assigned treatment. Infrared thermal imaging was used to collect temperature data on the areas of interest for analysis.
MAIN OUTCOME MEASURES:
The primary measure was the change in average temperature of the observed area after the intervention. The secondary measures included periodic temperature changes every 5 min and the temperature changes of the Governor Vessel and Bladder Meridian in the observed area after the intervention.
RESULTS:
Significant interactions were observed between treatments and acupoints affecting temperature (P < 0.001). The Acu-BL40 group showed a notably higher increase in mean temperature after 30 min compared to the Acu-LU5 and Mox-BL40 groups, with increases of 0.29 (95% confidence interval [CI] = 0.17 to 0.41) and 0.24 (95% CI = 0.08 to 0.41) °C, respectively.
CONCLUSION:
Acupuncture at BL40 acupoint can significantly increase the mean temperature in the observed area, highlighting the specific thermal effect of acupuncture compared to moxibustion in the lumbar area. This suggests a potential therapeutic benefit of acupuncture at BL40 for managing lumbar conditions.

ObjectiveTo explore the molecular mechanism by which gypenoside L (Gyp-L) promotes apoptosis and inhibits ovarian cancer (OC) through the FK506-binding protein (FKBP) prolyl isomerase 8 (FKBP8)/B-cell lymphoma-2 (Bcl-2) axis, with the piR-hsa-2804461 pathway as a breakthrough point. MethodsThe effects of different concentrations of Gyp-L and cis-platinum on the proliferation of OVCAR3 cells were determined by the cell count kit-8 method to identify the appropriate intervention concentration for subsequent experiments. OVCAR3 cells were allocated into blank, low-dose Gyp-L (Gyp-L-L, 50 µmol·L-1), high-dose Gyp-L (Gyp-L-H, 100 µmol·L-1), and cis-platinum (15 µmol·L-1) groups. The migration, colony formation, and apoptosis of OVCAR3 cells were detected by the cell scratch assay, colony formation assay, and flow cytometry, respectively. The mRNA levels of piR-hsa-2804461 and FKBP8/Bcl-2 axis-related genes in OVCAR3 cells were determined by Real-time PCR, and the expression levels of FKBP8/Bcl-2 axis-related proteins were determined by simple Western blot. Further, an OVCAR3 cell model with piR-hsa-2804461 knocked out was constructed. The cells were allocated into blank, NC-inhibitor, inhibitor, NC-inhibitor+Gyp-L, and inhibitor+Gyp-L groups. The colony formation of OVCAR3 cells was detected by the colony formation assay. The mRNA levels of piR-hsa-2804461 and FKBP8/Bcl-2 axis-related genes and the expression levels of FKBP8/Bcl-2 axis-related proteins were determined by Real-time PCR and simple Western blotting, respectively. ResultsGyp-L inhibited the migration and proliferation (P<0.01), promoted the apoptosis (P<0.05), up-regulated the mRNA level of piR-hsa-2804461 (P<0.05), and down-regulated the mRNA and protein levels of FKBP8 and Bcl-2 (P<0.05) in OVCAR3 cells. Furthermore, Gyp-L increased the mRNA and protein levels of Bcl-2-associated X protein (Bax), cysteinyl aspartate-specific proteinase (Caspase)-3, and Caspase-9, which are related to the FKBP8/Bcl-2 axis (P<0.05). ConclusionGyp-L may promote apoptosis by regulating the piR-hsa-2804461/FKBP8/Bcl-2 axis, thus affecting the occurrence of ovarian cancer.

ObjectiveWith the epidermal growth factor receptor(EGFR)/Signal Transducers and Activators of Transcription(STAT3)/Hexokinase 2(HK2) signaling pathway in atherosclerosis (AS) and ovarian cancer (OC) as the entry point, this paper discusses the molecular mechanism of Gypenoside L (Gyp-L) treating AS and OC with different diseases, provides a new perspective and theoretical basis for TCM treating AS and OC with EGFR-STAT3-HK2 pathway, and enriches the scientific connotation of the theory of "cytoskeleton in the heart". MethodsCCK-8 was used to detect the proliferation of HUVEC and OVCAR-3 cells, in order to determine the intervention concentration for subsequent experiments. The colorimetric method was used to detect the NO content in HUVEC and the contents of pyruvate and LDH in two cell lines. Cell cloning experiments and scratch experiments reflect the proliferation and migration ability of OVCAR-3 cells. Western blot was used to detect the expression levels of relevant proteins. Furthermore, two cell models overexpressing EGFR were constructed and co treated with Gyp-L. HUVEC cells were divided into control, ox-LDL, OE-NC, OE-EGFR, OE-NC+Gyp-L, and OE-EGFR+Gyp-L group. OVCAR-3 cells were divided into control, OE-NC, OE-EGFR , OE-NC+Gyp-L, and OE-EGFR+Gyp-L group. The colorimetric method was used to detect the NO content in HUVEC and the contents of pyruvate and LDH in two cell lines. Western blot was used to detect the expression levels of EGFR-STAT3-HK2 pathway related proteins. Cell cloning experiments and scratch experiments reflect the proliferation and migration ability of OVCAR-3 cells. ResultsGyp-L can significantly reduce the NO content of HUVEC and the pyruvate and LDH content of two cell lines (P<0.05); Inhibit the proliferation and migration ability of OVCAR-3 cells; Reduce the expression levels of EGFR/STAT3/HK2 pathway related proteins in HUVEC and OVCAR-3 cell lines (P<0.05), and inhibit the glycolysis pathway. ConclusionGyp-L can inhibit glycolysis in HUVEC and OVCAR-3 cells through the EGFR/STAT3/HK2 pathway,thereby suppressing the occurrence and development of AS and OC.
