Abstract
Shen chan decoction (SCD) as a significant Traditional Chinese medicine (TCM) to treat atopic dermatitis (AD), but its mechanism of action has not been clarified, so we started the present study, first possible effects of SCD on AD were predicted using network pharmacology. Next, dinitrochlorobenzene was used to establish a mouse model of AD. After successful modelling, the SCD were administered intragastrically to treat the mice. Eventually, the KEGG pathway enrichment analysis indicated that SCD improved AD mainly through effects on inflammation and the gut microbiota. The experimental findings revealed that SCD treatment attenuated AD symptoms and downregulate the characteristic immune factors, namely IL-4, IL-6 and IgE. Moreover, it promoted a balance between Th1/Th2 cells. Furthermore, the itch signaling pathways involving H1R/PAR-2/TRPV1 were inhibited. The 16S rRNA sequencing results indicated that SCD administration influenced the Firmicutes/Bacteroidetes ratio at the phylum level by augmenting the relative proportions of Lactobacillaceae and Muribaculaceae at the family and genus levels, while decreasing the abundances of Lactococcus and Ruminococcus. These findings suggest that internal administration of SCD is an effective therapeutic approach for AD. We suggest that SCD may be an alternative therapy for the treatment of AD.Additionally, it could offer valuable insights into the pathogenesis of AD and the development of innovative therapeutic agents.

Risk factors for short and long-term great saphenous vein recanalization in patients treated with endovenous radiofrequency ablation. Vascular 2023; 31:131-141.

Abstract
PURPOSE The aim of this retrospective single-center study is to describe and analyze short-, mid-, and long-term risk factors for great saphenous vein (GSV) recanalization after endovenous radiofrequency ablation (RFA). MATERIALS AND METHODS All consecutive patients with GSV incompetence and varicose veins underwent RFA were enrolled between 2009 and 2018. Data on demographic, pre- and postoperative color Doppler scan (CDUS) findings, perioperative complications, and follow-up were prospectively collected. Primary outcome was GSV recanalization rate at 1 week after RFA. Secondary outcomes were postoperative complication rate, as well as GSV recanalization rate at 1, 3, and 5 years after RFA. Risk factors for recanalization were also analyzed, for each follow-up assessment, identifying differences in recanalized (Rec) and non-recanalized (nRec) groups. RESULTS During the study period, 1297 patients were treated. Among these, 1265 had at least 1 week of follow-up. Mean follow-up time was 3.0 ± 1.9 years. Recanalization rate at 1 week, 1, 3, and 5 years was 2.4%, 4.3%, 9.3%, and 17.5%, respectively. After multivariate analysis for each follow-up evaluation, CEAP classes C4 and 5, as well as preoperative GSV diameter >6 mm and history of smoking were found to be independent predictors of recanalization. Furthermore, age >61 years and postoperative complications such as pigmentation, edema, and paresthesia were found to be dependent risk factors. CONCLUSION RFA remains a safe and durable technique to ablate incompetent GSV. Despite this, particular attention should be paid to patients with high CEAP classes to avoid short and long-term recanalization.

Abstract
Background This study investigated the distribution of valve incompetence in patients with chronic venous disease (CVD) and its correlation with the clinical category of the clinical, etiological, anatomical, and pathophysiological (CEAP) classification. Methods In total, 1,386 limbs with clinically suspected CVD were categorized according to the CEAP classification and consecutively underwent duplex ultrasonography between April 2017 and December 2020. Results There were 362 limbs in male patients and 1,024 limbs in female patients. The limbs were classified as C0s–C1 (608 limbs, 43.8%), C2 (727 limbs, 52.5%), or C3–C6 (51 limbs, 3.7%). The prevalence of saphenous vein incompetence in CEAP C0s–C1 limbs was 43.6%. The saphenofemoral junction (SFJ) was competent in 37% of CEAP C2–C6 limbs. The CEAP C3–C6 category was not correlated with reflux patterns of the saphenous vein system (Cramer’s V=0.07), incompetent SFJ (Cramer’s V=0.07), deep vein reflux (Cramer’s V=0.03), or the distribution of incompetent segments in the great saphenous vein (GSV) (Cramer’s V=0.11). Conclusion Duplex ultrasonography is necessary to formulate a proper treatment plan for limbs categorized as CEAP C0s–C1. The SFJ was competent in more than one-third of CEAP C2–C6 limbs with GSV reflux; as such, flush ligation of the GSV may be unnecessary in these patients. The CEAP C3–C6 category showed no correlations with reflux patterns of the saphenous vein system, SFJ reflux, deep vein reflux, or the distribution of incompetent segments in the GSV.

Abstract
Objectives To describe saphenous reflux patterns in patients classified as CEAP C2 by analysis of 2027 vascular ultrasound examination reports. Methods A total of 2027 venous mapping studies were reviewed and 1196 patients classified as CEAP C2 were selected. Patients were classified according to patterns of reflux for the great saphenous vein and for the small saphenous vein, and rates of great saphenous vein and small saphenous vein reflux were analyzed for both sexes. Results The overall prevalence of saphenous vein reflux was 45%. Males had significantly higher great saphenous vein reflux prevalence than females ( p < 0.001). The most common great saphenous vein reflux pattern in females was segmental reflux and the most common pattern in males was proximal reflux. Conclusions Saphenous vein reflux is common in C2 patients and is more frequent in males. Standardization of classifications of reflux patterns is very important for correct management of the disease.

Abstract
Objective Iliac vein stenting has been an evolving treatment option in the management of CVI secondary to iliac vein obstruction. Historically, treatment of CVI has been focused on the elimination of saphenous vein disease; however, the effect of reduction of iliac vein obstruction on superficial venous reflux remains largely unknown. This study aimed to identify the effect of iliac vein stenting on saphenous vein reflux. Methods In this retrospective study spanning course of five years, we performed 2681 venograms with venoplasties and stenting of the iliac veins. Pre-operative and post-operative venous mapping was performed via duplex ultrasonography. Patients who received any lower extremity vascular intervention between “pre-” and “post-stenting” duplex ultrasonography examination, other than iliac vein stenting, were excluded from analysis. Results One thousand six hundred forty-five patients, of which 63.2% were female, underwent iliac vein stenting; 1033 patients received bilateral intervention, whereas 356 and 259 patients received unilateral left and right stenting, respectively. The average age of the patient cohort was 66 (range 22–100; SD ± 13.9). The distribution CEAP scores of each limb at the time of intervention were: C2 (1%), C3 (25%), C4 (51%), C5 (5%), and C6 (18%). Bilateral iliac vein stenting significantly reduced reflux in the bilateral great saphenous and small saphenous veins by 363.8 ms ( p < 0.0001) and 345.4 ms ( p < 0.0002), respectively, but had no effect on ASV reflux. Unilateral stenting did not produce significant reductions in reflux, besides an average reduction of 573.2 ms ( p = 0.004) in the left great saphenous vein. Conclusion Bilateral iliac vein stenting decreased great saphenous vein and small saphenous vein reflux. Unilateral stenting did not demonstrate a significant reduction in saphenous reflux. Bilateral reduction in stenosis of the iliac veins may influence superficial venous reflux.
