Ulcerative colitis(UC)is a recurrent,chronic,nonspecific inflammatory bowel disease.Shaoyao Decoction has shown good efficacy in the treatment of UC,which mainly regulates the balance of cytokines to achieve the purpose of treating UC.This article reviewed the research progress in the mechanism of Shaoyao Decoction in the treatment of UC from two aspects of pro-inflammatory cytokines and anti-inflammatory cytokines.Research has shown that Shaoyao Decoction can regulate the body's immune response,alleviate intestinal inflammation,protect the intestinal mucosal barrier,restore normal structure and function of the colon mucosa through pro-inflammatory cytokines such as tumor necrosis factor-α,interferon-γ,interleukin(IL)-1β,IL-6,IL-8,IL-17,and anti-inflammatory cytokines such as transforming growth factor-β,IL-4,IL-10,IL-13,which can provide reference for UC related mechanism research and clinical treatment.

The reconstruction of the temporomandibular joint presents a multifaceted clinical challenge in the realm of head and neck surgery, underscored by its relatively infrequent occurrence and the lack of comprehensive clinical guidelines. This review aims to elucidate the available approaches for TMJ reconstruction, with a particular emphasis on recent groundbreaking advancements. The current spectrum of TMJ reconstruction integrates diverse surgical techniques, such as costochondral grafting, coronoid process grafting, revascularized fibula transfer, transport distraction osteogenesis, and alloplastic TMJ replacement. Despite the available options, a singular, universally accepted 'gold standard' for reconstructive techniques or materials remains elusive in this field. Our review comprehensively summarizes the current available methods of TMJ reconstruction, focusing on both autologous and alloplastic prostheses. It delves into the differences of each surgical technique and outlines the implications of recent technological advances, such as 3D printing, which hold the promise of enhancing surgical precision and patient outcomes. This evolutionary progress aims not only to improve the immediate results of reconstruction but also to ensure the long-term health and functionality of the TMJ, thereby improving the quality of life for patients with end-stage TMJ disorders.

Objective To track and evaluate the implementation of the Radiation Shielding Requirements in Room of Radiotherapy Installations—Part 1: General Principle (GBZ/T 201.1–2007) among relevant personnel in medical radiation institutions, and to provide a scientific basis for revising the standard. Methods According to the Guidelines for Health Standards Tracking Evaluation (WS/T 536–2017) and the implementation protocol of standard evaluation, an online survey was conducted among 212 relevant workers from 146 medical radiation institutions across 18 provinces in China. The data were aggregated and analyzed with the use of Microsoft Excel 2010. Results A total of 215 questionnaires were returned, of which 212 were valid. Among the valid respondents, 77.8% believe that this standard is universally applied; 96.2% believe that this standard can meet work needs; 63.7% have participated in relevant training on this standard; 74.1% use this standard once or more per year; and 10.8% believe that this standard needs to be revised. Conclusion Medial radiation workers have a high rate of awareness of the basic information and content of the standard, but the understanding and application of the standard content need to be improved. We recommend that relevant departments further strengthen the promotion of and training on the standard, revise some content based on actual situation, and improve workers’ ability to use the standard.

Objective:To compare the efficacy of unilateral percutaneous kyphoplasty (PKP) and unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve in the treatment of lumbar osteoporotic vertebral compression fracture (OVCF) in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 161 aged patients with newly developed lumbar OVCF, admitted to Xi′an Central Hospital Affiliated to Xi′an Jiaotong University School of Medicine from January 2019 to January 2023, including 58 males and 103 females, aged 61-88 [(72.9±6.3)years]. All the patients were diagnosed with type II compression fracture based on acute symptomatic osteoporotic thoracolumbar fracture classification (ASOTLF). Seventy-eight patients underwent unilateral PKP (PKP group), while the other 83 patients underwent unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve (PKP+contralateral block group). The operation time, intraoperative blood loss, and length of hospital stay were recorded. Beck index of the injured vertebra, Cobb angle of lumbar lordosis, Roland-Morris disability (RMD) score, visual analogue scale (VAS), and Oswestry disability index (ODI) were evaluated before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up. The incidence of complications such as cement leakage was recorded as well.Results:All the patients were followed up for 6-8 months [(6.7±0.6)months]. There were no significant differences between the two groups in the operation time, intraoperative blood loss, or length of hospital stay ( P>0.05). The Beck index of the injured vertebra and Cobb angle of lumbar lordosis were not significantly different between the two groups before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up ( P>0.05). The RMD score of the injured vertebra, VAS score, and ODI were not significantly different between the two groups before operation ( P>0.05). At 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up, the RMD scores in the PKP+contralateral block group were (11.23±1.05)points, (10.90±1.11)points, (10.10±1.06)points, (9.94±1.06)points, and (9.60±0.83)points respectively, which were all lower than (17.55±0.71)points, (15.78±0.86)points, (13.42±0.92)points, (10.67±0.78)points, and (9.78±0.72)points in the PKP group ( P<0.05 or 0.01); the VAS scores in the PKP+contralateral block group were (3.02±0.60)points, (2.96±0.55)points, (2.92±0.57)points, (2.88±0.61)points, and (2.70±0.51)points respectively, which were all lower than (3.60±0.57)points, (3.47±0.55)points, (3.32±0.46)points, (2.99±0.47)points, and (2.77±0.42)points in the PKP group ( P<0.05 or 0.01); the ODI values in the PKP+contralateral block group were 14.43±1.29, 14.54±1.24, 14.63±1.32, 14.37±1.31, and 13.42±1.45 respectively, which were all lower than 16.72±1.64, 16.09±1.49, 14.82±1.53, 14.74±1.46, and 13.69±1.75 in the PKP group ( P<0.05 or 0.01). The bone cement leakage rate was 12.0% (10/83) in the PKP+contralateral block group, similar to 11.5% (9/78) in the PKP group ( P>0.05). No other complications such as neurovascular injury, pulmonary embolism or adjacent vertebral fracture were found in either groups. Conclusion:In the treatment of lumbar OVCF in the elderly, unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve is similar to unilateral PKP in terms of the operation time, intraoperative blood loss, length of hospital stay, effectiveness of reduction, and incidence of complications, but it can achieve better pain relief and more satisfactory functional recovery.

Gypenosides, structurally analogous to ginsenosides and derived from a sustainable source, are recognized as the principal active compounds found in Gynostemma pentaphyllum, a Chinese medicinal plant used in the treatment of the metabolic syndrome. By bioactive tracking isolation of the plants collected from different regions across China, we obtained four new gypenosides (1-4), together with nine known gypenosides (5-13), from the methanol extract of the plant. The structures of new gypenosides were elucidated by one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectra, complemented by chemical degradation experiments. Through comprehensive evaluation involving COL1A1 promoter assays and PP2Cα activity assays, we established a definitive structure-activity relationship for these dammarane-type triterpenoids, affirming the indispensability of the C-3 saccharide chain and C-17 lactone ring in effectively impeding extracellular matrix (ECM) deposition within hepatic stellate cells. Further in vivo study on the CCl₄-induced liver damage mouse model corroborated that compound 5 significantly ameliorated the process of hepatic fibrosis by oral administration. These results underscore the potential of dammarane-type triterpenoids as prospective anti-fibrotic leads and highlight their prevalence as key molecular frameworks in the therapeutic intervention of chronic hepatic disorders.

Objective: To establish a three-dimensional coordinate system that can accurately measure the recurrence rate after orthognathic surgery, and evaluate and analyze the degree of recurrence. Methods : Data from patients who underwent orthognathic surgery in a hospital were selected to reconstruct three-dimensional images with spiral CT. The two researchers used the multiplane assisted positioning method to fix the points three times and screened them using intra-andintreclass correlation coefficients (ICC). Reproducible and accurate landmark points were drawn to establish different coordinate systems and calculate the facial asymmetry index (AI) to determine the coordinate system with the best mid-sagittal plane symmetry. This coordinate system and lateral radiographs were used to separately measure the recurrence rate, and evaluate and analyze the three-dimensional recurrence degree of orthognathic surgery. Results : Ten landmark points that may be repeatedly fixed were obtained, including N (nasion), K (K point), ANS(anterior nasal spine), PNS (posterior nasal spine), Ptm(pterygomaxillary fissure), Gn (gnathion), IZ(IZ point), MZ (MZ point), Ms (mastoideale), Cor (coronion) and and Go (gonion). Three coordinate systems were established, and the most suitable coordinate system was the upper edge point of the left infraorbital foramen. The inner upper edge of the right infraorbital foramen and both sides of the midpoint of the ear points constituted the horizontal plane (HP), which passed through the outermost point of the left zygomatic frontal suture and the outermost point of the right zygomatic frontal suture and was perpendicular to the horizontal plane to constitute the coronal plane (CP). It was perpendicular to the two planes to form a sagittal plane (SP). Two-dimensional and three-dimensional measurements of recurrence were performed on 112 patients, and new three-dimensional recurrence evaluation results were obtained. Less than 40% had low recurrence, 40% to 61% had moderate recurrence, and greater than 61% had high recurrence. Conclusion This study established a three-dimensional coordinate system suitable for measuring the recurrence rate after orthognathic surgery, obtained a new three-dimensional recurrence evaluation result, and provided a clinical experimental basis for evaluating the effect of orthognathic surgery and improving stability.
