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 management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group (79 patients) undergoing fistulectomy without granulation treatment, and a control group (61 patients) where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale(SBSES). Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

ObjectiveTo investigate the mechanism of Ershiwuwei Guijiu pill in preventing and treating postmenopausal osteoporosis (PMOP) by activating the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway and inhibiting excessive autophagy. MethodFemale SD rats were ovariectomized and randomly divided into the sham operation group (Sham), the operation group (OVX), the Ershiwuwei Guijiu pill (GJ) group, and the raloxifene hydrochloride (RLX) group, with 10 rats in each group. Enzyme-linked immunosorbent assay (ELISA) and colorimetric methods were used to detect the levels of estrogen, bone metabolism markers in serum, and total superoxide dismutase (T-SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) in tibial tissue. Flow cytometry was used to detect reactive oxygen species (ROS) levels in bone marrow mesenchymal stem cells. Masson staining was used to observe pathological changes in the proximal tibia, and micro-computed tomography (Micro-CT) was used to observe changes in tibial microstructural parameters. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to detect the expression of autophagy-related proteins Beclin1, microtubule-associated protein 1A/1B-light chain 3 (LC3), autophagy-related 5 (Atg5), as well as PI3K, Akt, and mTOR in tibial tissue. ResultCompared with the Sham group, the OVX group showed a significant decrease in serum levels of estradiol (E2) and calcium ion (Ca2+), and T-SOD, GSH-Px, PI3K, Akt, and mTOR mRNA levels in bone tissue (P<0.05, P<0.01), significantly reduced bone mineral density (BMD), bone surface/bone volume (BS/BV), trabecular thickness (Tb.Th), trabecular number (Tb.N), and trabecular connectivity (Con) in the tibia (P<0.05, P<0.01), thinner epiphyseal growth plate, and the bone marrow cavity filled with fat vacuoles. Moreover, the levels of phosphorus (P), MDA, ROS, and mRNA and protein expression of Beclin1, LC3, and Atg5, as well as trabecular separation (Tb.Sp) were significantly elevated (P<0.05, P<0.01). Compared with the OVX group, the GJ and RLX groups showed significant increases in serum E2 and Ca2+, and bone tissue levels of SOD, GSH-Px, and the mRNA levels of PI3K, Akt, and mTOR (P<0.05, P<0.01), significantly increased BMD, BS/BV, Tb.Th, Tb.N, and Con in the tibia, thickened epiphyseal growth plate, and significantly reduced fat vacuoles in the bone marrow cavity (P<0.05, P<0.01). Additionally, the levels of P, MDA, ROS, Beclin1, LC3, Atg5 mRNA and proteins, and Tb.Sp were significantly decreased (P<0.05, P<0.01). The ratios of p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR, which were significantly reduced in the OVX group (P<0.01), were significantly increased in the GJ and RLX groups (P<0.01). ConclusionThe Ershiwuwei Guijiu pill reduces oxidative stress and inhibits autophagy, thereby preventing and treating postmenopausal osteoporosis. Its mechanism may be related to the activation of the PI3K/Akt/mTOR signaling pathway, which inhibits autophagy.

【Objective】 To analyze the genetic variation characteristics and clinical phenotypes of a family with primary microcephaly (MCPH) caused by RTTN gene variation, and to provide reference for genetic counseling and prenatal diagnosis. 【Methods】 Clinical data of the three patients (including 2 fetuses and 2-year-old proband,and one fetus with clinical diagnosis) and their parents were collected and analyzed. Two of the children and their parents were tested by trio whole exome sequencing (trio-WES), sanger sequencing validation sites, and the hazard of their compound heterozygous variants was predicted. Literature review was conducted through domestic and international databases to collect reported RTTN gene mutation cases. 【Results】 Three patients in this family had anomalies of the septum pellucidum, hypoplasia of the corpus callosum and other brain malformations during fetal period. The proband (G2) and fetus (G3) showed intrauterine growth retardation and MCPH in late pregnancy; besides, G2 was born with global developmental delay. Trio-WES detected a c.2101(exon16)C>T(p.Arg701Ter,1526) nonsense and a c.2863(exon22)G>A(p.Glu955Lys)missense in the RTTN gene of G2 and G3, which were inherited from their father and mother, forming a compound heterozygous variant. According to the American College of Medical Genetics and Genomics (ACMG) variant classification guidelines, two variants were likely to be pathogenic (LP) and uncertain significance (VUS). Among them, c.2863(exon22)G>A was a newly discovered missense, which was predicted by the software to be harmful to the gene product. 【Conclusions】 Complex heterozygous variations of RTTN gene (c.2101C>T and c.2863G>A) are the genetic cause of MCPH in this family. This report has enriched the variation spectrum of RTTN gene, provided guidance for prenatal diagnosis and reproduction of this family, as well as material and reference for further understanding of the diseases caused by this gene mutation.

Objective:To analyze the current situation of pregnant women′s health promotion behavior in early pregnancy, and to explore the multiple mediating effects of self-efficacy and sense of coherence in family function and health promotion behavior.Methods:The convenience sampling method selected 208 early pregnant women who visited the obstetric clinic of the Affiliated Hospital of Qingdao University from August to December 2020 as the research object was used. The electronic questionnaires including self-made general information questionnaire, Family APGAR Questionnaire, General Self-Efficacy Scale (GSES), Sense of Coherence Scale (SOC-13), and the Health-Promoting Lifestyle ProfileⅡ (HPLP-Ⅱ) were provided to women.Results:The total score of health promotion behaviors for early pregnancy was (139.58 ± 17.27) points with a good level. The influencing factors such as exercise habits and medical payment methods had statistical significance in the effects of health-promoting behaviors in the first trimester of pregnancy ( t=4.68, -3.55, both P<0.05). Structural equation model revealed that the total effect value of family function on health-promoting behaviors was 2.654, the direct effect value was 1.729 and the indirect effect value was 0.925. Meanwhile, the mediating effects of self-efficacy, the sense of coherence and self-efficacy upon the sense of coherence accounted for 15.9%, 15.2% and 3.8% of the indirect effect respectively. Conclusions:Family function of pregnant women in early pregnancy can not only affect health promotion behavior through self-efficacy and sense of coherence, but also indirectly affect sense of coherence through self-efficacy, so as to affect health promotion behavior. Maternal related health workers can construct targeted intervention measures from the perspective of self-efficacy and sense of coherence to maintain and improve the health promotion behavior of pregnant women in the early stage of pregnancy.
