Background: Moderate to severe breast pain has major effects on the quality of life for patients. Patent Chinese medicines are widely used in the treatment of breast pain due to their stable dosage form and good ***: To evaluate the beneficial effects and safety of Hongjin Xiaojie Capsule(HJXJC), a Chinese patent medicine, for the treatment of cyclical breast ***, setting, participants and intervention: This is a multicenter, single-blind randomized controlled trial conducted in 3 medical centers in China from 2019 to 2021. Patients with moderate to severe cyclic breast pain were randomly divided into the intervention group(who took HJXJC, four capsules per dose,three times a day for 12 weeks) and the control group(waiting for the treatment) in a 1:1 *** outcome measures: The primary outcome was pain duration, and the patients recorded measurements at baseline and at the end of weeks 4, 8, 12 and 16 on a patient log ***: The full analysis set(FAS) population included 298 participants(intervention group, n = 150;control group, n = 148), while the per-protocol analysis set(PPS) included 274 participants. After12 weeks, the duration of breast pain was significantly shorter in the intervention group(FAS: mean difference, –6.69; 95% CI, –7.58 to –5.80; P < 0.01, vs control. PPS: mean difference, –7.09; 95% CI, –8.01 to –6.16; P < 0.01, vs control). The Short-form McGill Pain Questionnaire(SF-MPQ) scores were significantly lower in the intervention group(FAS: mean difference, –12.55; 95% CI, –13.90 to –11.21; P < 0.01, vs control. PPS: mean difference, –13.07; 95% CI, –14.48 to –11.66; P < 0.01, vs control). The above indicators continued to be significantly different through week 16. Moreover, in the intervention group, breast lumps shrank after 12 weeks and the size of breast lumps was statistically smaller than that in the control group(P < 0.05), whereas the sizes of breast nodules and uterine fibroid showed no statistically sign

EFFECT OF INTERLEUKIN-1β ON GROWTH HORMONE GENE EXPRESSION AND ITS POSSIBLE MOLECULAR MECHANISM IN RAT MtT/S SOMATOTROPH CELLS

引用

Chinese Medical Sciences Journal 2008年第4期23卷 193-201页

Objective To elucidate the effect of interleukin-1β （IL- 1β） on human growth hormone （hGH） gene expression in a rat somatotropic pituitary cell line MtT/S. Methods Stably transfected MtT/S cells were firstly established by transfecting 484-Lucl plasmid which contained hGH gene promoter --484 to ＋30 bp and luciferase reporter gene. The effect of IL-1β on hGH gene expression was determined by assaying the luciferase activities. RT-PCR method was also used to determine whether IL-1 recepor mRNA was expressed in MtT/S cells. Results The 10^3 U/mL IL-1β stimulated secretion and synthesis of GH, and promoted the 5＇-promoter activity of GH gene in stably transfected MtT/SGL cells with the action of 1.38 times above the control. Among inhibitors of signaling transduction pathways, mitogen-activated protein kinase kinase （MAPKK/MEK） inhibitor PD98059 （40 μmol/L） and p38 mitogen-activated protein kinase （MAPK） inhibitor SB203580 （5 μmol/L） completely blocked the stimulatory effect of IL-1μ, and phosphatidylinositol-3-kinase （PI3-K） inhibitor LY294002 partly abolished the effect of IL-1μ. Western blot analysis further confirmed the activation of phosphorylated MEK and p38 MAPK in MtT/SGL cells. Neither over-expression of Pit- 1 nor inhibition of Pit- 1 expression affected induction of hGH promoter activity by IL-1μ. A series of deletion constructs of hGH promoter were created to identify the DNA sequence that mediated the effect of IL-1β, and results showed that the stimulatory effect of IL-1β was abolished following deletion of the --196 to -- 132 bp fragment. Conclusions IL-1β promotes GH secretion and synthesis in rat MtT/S somatotroph cells. The stimulatory effect of IL-1β on hGH gene promoter appears to require the activation of MEK, p38 MAPK, PI3-K, and a fragment of promoter sequence that spans the -196 to -132 bp of the gene, but it may be unlinked with Pit-1 protein.

Accurate mapping of loess waterworn gully(LWG)is essential to further study gully erosion and geomorphological evolution for the Chinese Loess Plateau(CLP).Due to the vertical joint and collapsibility of loess,LWGs have the characteristics of zigzag and unique slope abruptness under synthetic action of hydraulic force and *** forces existing LWG mapping methods to either focus on the improvement of mapping accuracy or center on the increase of mapping ***,simultaneously achieving accurate and efficient mapping of LWG is still in its infancy under complex topographic ***,we proposed a method that innovatively integrates the loess slope abruptness feature into an improved deep learning semantic segmentation framework for LWG mapping using 0.6 m Google imagery and 5 m DEM *** selected four study areas representing typical loess landforms to test the performance of our *** proposed method can achieve satisfactory mapping results,with the F1 score,mean Intersection-over-Union(mIoU),and overall accuracy of 90.5%,85.3%,and 92.3%,*** addition,the proposed model also showed significant accuracy improvement by inputting additional topographic information(especially the slope of slope).Compared with existing algorithms(Random forests,original DeepLabV3+,and Unet),the proposed approach in this study achieved a better accuracy-efficiency ***,the method can ensure high accuracy and efficiency of the LWG mapping for different loess landform types and can be extended to study various loess gully mapping and water and soil conservation.

Vascular embolization treatment, a minimally invasive surgery for various blood vessel-related conditions, has emerged as a crucial method in treating such as hemorrhage, arteriovenous malformation, aneurysms, and hypervascular tumors. Liquid embolic agents are gaining prominence due to their distinct advantage in infiltrating distal regions, expanding the scope of embolization beyond the reach of solid agents. Recent strides in biomaterials and technologies have spurred the development of novel liquid embolic agents, addressing challenges posed by traditional options. This mini-review provides a concise overview of the recent progress in water-based liquid embolic agents, highlighting their potential to overcome limitations associated with current embolic materials. By presenting selected research outcomes, we illuminate advancements that enhance the efficacy of liquid embolic agents. Furthermore, the review outlines essential properties for effective liquid embolic agents, offering insights for future developments in this field.
