Objective: Accurate evaluation of inflammation severity in ulcerative colitis (UC) can guide treatment strategy selection. The potential value of the pericolic fat attenuation index (FAI) on CT as an indicator of disease severity remains unknown.This study aimed to assess the diagnostic accuracy of pericolic FAI in predicting UC severity. Materials and Methods: This retrospective study enrolled 148 patients (mean age 48 years; 87 males). The fat attenuation on CT was measured in four different locations: the mesocolic vascular side (MS) and opposite side of MS (OMS) around the most severe bowel lesion, the retroperitoneal space (RS), and the subcutaneous area. The fat attenuation indices (FAI MS, FAI OMS, and FAI RS) were calculated as the fat attenuation measured in MS, OMS, and RS, respectively, minus that of the subcutaneous area, and were obtained in the non-enhanced, arterial, and delayed phases. Correlations between the FAI and UC Endoscopic Index of Severity (UCEIS) were assessed using Spearman’s correlation. Predictors of severe UC (UCEIS ≥7) were selected by univariable analysis. The performance of FAI in predicting severe UC was evaluated using the area under the receiver operating characteristic curve (AUC). Results: The FAIMS and FAI OMS scores were significantly higher than FAI RS in three phases (all P < 0.001). The FAIMS and FAI OMS scores moderately correlated with the UCEIS score (r = 0.474–0.649 among the three phases). Additionally, FAI MS and FAI OMS identified severe UC, with AUC varying from 0.77 to 0.85. Conclusion Increased CT attenuation of pericolic adipose tissue could serve as a noninvasive marker for evaluating UC severity. FAI MS and FAI OMS of three phases showed similar prediction accuracies for severe UC identification.

Objective To investigate the role of lncSIL in transforming growth factor-β1(TGF-β1)-induced alveo-lar epithelial interstitial transformation(EMT)and its related signaling pathways.Methods Western blot was used to detect the effect of lncSIL silencing on the expression of E-cadherin(E-cad),alpha-smooth muscle actin(α-SMA)and Collagen I(Col I)in the process of EMT induced by TGF-β1.LncSIL interacting proteins were ana-lyzed by RNA pulldown.Western blot was used to detect the effect of overexpression or silencing of lncSIL on the expression of its target gene enhancer of zeste homolog 2(EZH2)and its downstream factors P21 and cyclin-de-pendent kinase 6(CDK6).Flow cytometry was used to analyze the effect of lncSIL on cell cycle progression.Re-sults After lncSIL silencing,the expression of α-SMA and Col I increased,the expression of E-cad decreased.RNA pulldown assay showed that EZH2 was the target protein that interacted with lncSIL,and the expression of EZH2 increased after silencing lncSIL,the expression of EZH2 downstream gene P21 decreased,CDK6 increased.Flow cytometry showed that the number of cells in S phase significantly increased.When lncSIL was overexpressed,the expression of EZH2 and CDK6 was down-regulated,the expression of P21 was up-regulated,and the number of S phase cells significantly decreased.Conclusion LncSIL inhibits TGF-β1-induced alveolar epithelial cell mesen-chymal transition by negatively regulating EZH2/P21/CDK6 signaling pathway to inhibit cell cycle progression.

Normal human blood pressure has a certain circadian rhythm,which is high during the day and low at night,and two peaks and one valley of the arytenoid change. The theory of opening-closing-pivot is an essential part of the yin and yang theory in traditional Chinese medicine,which reflects the law of qi movement changes of the three yin and three yang. According to "time to heal six channels" in Shanghan Lun,the opening-closing-pivot of three yin and three yang have their own time. Following certain time laws,the ascending,descending,exiting,and entering of the yin and yang qi movement conform to the circadian rhythm,which is the basis for maintaining the normal circadian rhythm of human blood pressure. Jueyin closing and shaoyang pivot mainly regulate morning blood pressure,whereas yangming closing,taiyin opening,and shaoyin pivot mainly regulate night blood pressure. The opening-closing-pivot of three yin and three yang coordinate and influence each other to maintain the stability of the circadian rhythm of blood pressure. The abnormal opening-closing-pivot can lead to the disturbance of the circadian rhythm of blood pressure,which primarily manifests as early morning hypertension caused by jueyin closing and shaoyang pivot failure,and night hypertension caused by yangming closing,taiyin opening and shaoyin pivot failure. By adjusting the movement of opening-closing-pivot of three yin and three yang,the blood pressure of corresponding period can be regulated. Combined with Western medical research,a new idea and method of regulating the circadian rhythm of blood pressure with traditional Chinese medicine is put forward.

Primary multiple pulmonary nodules have a high incidence,and the size and number of pulmonary nodules on computed tomography images increase with time.Postoperative pathology of multiple pulmonary nodules shows chronic inflammation,adenomatoid change,carcinoma in situ,microinvasive carcinoma,infiltrating carcinoma,and other forms.There is a possibility of"inflammation-cancer transformation"in multiple pulmonary nodules with prolonged time and external irritation.The accumulation of dampness phlegm and blood stasis is the basis of the theory of"inflammation-cancer transformation."Healthy qi deficiency is the key to the"inflammation-cancer transformation."Qi and yang deficiency are the root cause of healthy qi depletion.Emotional depression,dampness,phlegm,and blood stasis transforming into toxins provide the impetus for"inflammation-cancer transformation."There are struggle between healthy qi and evil qi,and waxing and waning of dampness,phlegm and blood stasis in the process of"inflammation-cancer transformation."The dampness phlegm and blood stasis will increase when evil qi increases and healthy qi decreases.In contrast,the size,number,and malignancy of nodules will increase during healthy qi deficiency,showing a dynamic shift from inflammation to atypical adenomatous hyperplasia to cancer.The dampness phlegm and blood stasis will be absorbed as the healthy qi increases and evil qi decreases so that lung cancer can be reversed.External irritation,such as acute inflammatory stimulation,may accelerate the transformation of"inflammation-cancer"in multiple pulmonary nodules.

Objective:To explore the clinical application value of magnetic stimulation combined with biofeed-back technology in female stress urinary incontinence(SUI).Methods:Sixty mild or moderate female SUI patients who underwent rehabilitation treatment at the Pelvic Floor Rehabilitation Center of Nanjing Women and Children's Healthcare Hospital from July to December 2021 were collected and randomly divided into two groups,with 30 pa-tients in each group.The observation group received a treatment protocol of electrical stimulation+biofeedback therapy(electric combined group)and the other group received a treatment protocol of magnetic stimulation+bi-ofeedback therapy(magnetic combined group).The treatment course for both groups consisted of 12 sessions.The Sandvik severity Index(urinary incontinence),the amount of u 1-hoururine leakage,pelvic floor muscle strength,pelvic floor muscle electrophysiological indices,the degree of urinary incontinence impact(ⅡQ-7 score)and the treatment efficacy were assessed and compared before and after the treatment in the two groups.Re-sults:Compared with the pre-treatment,the Sandvik Severity Index,the 1-hour urine leakage,and the n Q-7 score decreased in the magnetic combined group and the electric combined group after treatment,while the mus-cle strength of type Ⅰ,type Ⅱ,maximum of fast muscle,and mean value of slow muscle increased significantly,and the differences were statistically significant(P＜0.05).The difference between the above indexes was not statistically significant when comparing the magnetic combined group and the electric combined group after treat-ment(P＞0.05),and the treatment efficiency of the electric combined group was 93.33％and that of the magnet-ic combined group was 96.67％,and there was no statistical significance when comparing the efficiency of the two groups(P＞0.05).Conclusions:Magnetic stimulation combined with biofeedback technology has high thera-peutic efficiency for mild or moderate SUl,and is an optional rehabilitation technique for women with SUI.
