ObjectiveTo investigate the efficacy and safety of Shuganning injection in the treatment of liver injury by observing the clinical outcome of patients with liver injury after treatment with Shuganning injection and comparing it with reduced glutathione （GSH）. MethodsThis study was conducted among 175 patients with liver injury who attended 6 hospitals in China （Beijing YouAn Hospital， Capital Medical University； Nanyang First People’s Hospital； The Second Affiliated Hospital of Xi’an Jiaotong University； The Fifth Medical Center of Chinese PLA General Hospital； The Third Hospital of Hebei Medical University； The Affiliated Hospital of Guizhou Medical University） from April 25， 2019 to February 28， 2022. The patients were divided into experimental group （89 patients treated with Shuganning injection） and control group （86 patients treated with GSH）， and the course of treatment was 4 weeks for both groups. Related indicators were recorded before treatment， after treatment， and after drug withdrawal for 8 weeks， including liver function parameters， blood biochemical parameters， blood lipids， coagulation profiles， liver fibrosis markers， traditional Chinese medicine （TCM） syndrome score， and ultrasound findings， as well as adverse events during treatment. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The Wilcoxon signed-rank test was used for comparison of observation indicators before treatment， at week 4 of treatment， and after drug withdrawal for 8 weeks. When the efficacy evaluation of TCM syndromes was used as the outcome， a pooled analysis was performed for the effective cases and the markedly effective cases， and a Logistic regression model was used to calculate the odds ratio （OR） and its 95%CI. ResultsAfter 4 weeks of treatment with Shuganning injection， the patients showed significant reductions in TCM syndrome score （P<0.001） and the levels of aspartate aminotransferase， alanine aminotransferase， total bilirubin， and direct bilirubin （all P<0.001） and a significant increase in the level of albumin （P=0.002）， and these significant improvements persisted after drug withdrawal for 8 weeks. Furthermore， compared with the control group， the experimental group had a significantly higher proportion of patients assessed as effective or markedly effective cases （48.31% vs 32.56%， P=0.033）. Compared with the control group， the experimental group had a significantly greater change in TCM syndrome score at weeks 1-4 of treatment and after drug withdrawal for 8 weeks （P<0.05）. At week 4 of treatment， the experimental group had a significantly greater reduction in alanine aminotransferase than the control group （P<0.05）， and at week 8 after drug withdrawal， the experimental group had a significantly greater reduction in alanine aminotransferase and aspartate aminotransferase than the control group （all P<0.05）. One patient in the experimental group （1.12%） experienced an adverse event， which was determined to be associated with the progression of viral hepatitis. ConclusionShuganning injection can effectively improve liver injury， with good long-term efficacy and a low incidence rate of adverse reactions.

Objective:To explore the position and length of anchor placement during the repair of anterior talofibular ligament (ATFL) in adolescents with unclosed epiphyseal plates by measuring the relevant data in three-dimensional CT.Methods:A total of 100 three-dimensional CT images of adolescent patients with unclosed epiphyseal plates were collected from the database of the Radiology Center of Renhe Hospital Affiliated to China Three Gorges University from January 1, 2017 to January 1, 2024. There were 69 males and 31 females, aged 12.38±0.90 years (range, 11-14 years), 47 on the left side and 53 on the right side, with a height of 155.72±5.84 cm (range, 145-175 cm), a weight of 48.02±5.93 kg (range, 40-72 kg), and a body mass index (BMI) of 19.77±1.61 kg/m 2 (range, 17.69-24.91 kg/m 2). The built-in measurement tool of the picture archiving and communication system (PACS) was used to measure the angle (α) between the direction of the nail placement and the longitudinal axis of the fibula, the distance between the nail placement point and the posterior edge of the fibula ( d), and the height from the nail placement point to the level of the fibula tip ( h) to evaluate the position and length of the anchor placement. Results:In adolescent patients, α was 47.50°±3.28° (range, 40.00°-56.00°), d was 17.12±1.80 mm (range, 11.70-21.90 mm), and h was 5.21±1.17 mm (range, 3.40-7.90 mm). The α, d and h of male patients were 47.48°±3.13° (range, 42.00°-56.00°), 17.49±1.54 mm (range, 14.45-21.90 mm) and 5.25±1.07 mm (range, 3.70-7.90 mm), respectively. Those of female patients were 47.55°±3.66° (range, 40.00°-53.00°), 16.30±2.07 mm (range, 11.65-20.30 mm) and 5.07±1.56 mm (range, 3.40-7.00 mm), respectively. There was a significant difference in d between male and female patients ( t=3.193, P=0.002), but there was no significant difference in α and h ( t=0.098, P=0.922; t=0.296, P=0.770). Conclusions:The safe range of anchor placement during ATFL anatomical repair in adolescents with unclosed epiphyseal plates is about 3.40-7.90 mm above the tip of fibula and 56°-90° with the longitudinal axis of fibula. Male patients with unclosed epiphyseal plates should choose anchors with a length of 14 mm and shorter, while females should choose anchors with a length of 10.8 mm.

Organoid models are used to study kidney physiology, such as the assessment of nephrotoxicity and underlying disease processes. Personalized human pluripotent stem cell-derived kidney organoids are ideal models for compound toxicity studies, but there is a need to accelerate basic and translational research in the field. Here, we developed an automated continuous imaging setup with the "read-on-ski" law of control to maximize temporal resolution with minimum culture plate vibration. High-accuracy performance was achieved: organoid screening and imaging were performed at a spatial resolution of 1.1 μm for the entire multi-well plate under 3 min. We used the in-house developed multi-well spinning device and cisplatin-induced nephrotoxicity model to evaluate the toxicity in kidney organoids using this system. The acquired images were processed via machine learning-based classification and segmentation algorithms, and the toxicity in kidney organoids was determined with 95% accuracy. The results obtained by the automated "read-on-ski" imaging device, combined with label-free and non-invasive algorithms for detection, were verified using conventional biological procedures. Taking advantage of the close-to-in vivo-kidney organoid model, this new development opens the door for further application of scaled-up screening using organoids in basic research and drug discovery.

Subchondral insufficiency fracture (SIF) of the femoral head is one of the predominant etiologies of rapidly progressive osteoarthritis of the hip (RPOH). SIF is a rare disease that causes acute pain in the hip joint. It is most frequently found in elderly women with osteoporosis. It is often underdiagnosed or misdiagnosed as osteonecrosis of the femoral head. SIF is currently a well-established cause of RPOH; however, the deeper etiology of SIF is not clear. Good clinical outcomes have been reported for hip preservation therapy and hip replacement. SIF is not obvious radiologically in the early stage, and a T1-weighted magnetic resonance imaging shows a discontinuous low-intensity band under the articular cartilage convex to the articular surface as its characteristic manifestation. Some patients will lose the opportunity to preserve the hip joint due to symptoms such as progressive joint space narrowing and subchondral collapse within a very short period. Patients with progressive hip space narrowing and subchondral collapse on Xray should be converted to total hip arthroplasty. Based on the characteristics of the disease, surgeons need to master the clinical and radiological characteristics of SIF and strive for early diagnosis and treatment.

Total hip arthroplasty (THA) has been one of the most successful orthopaedic surgery in the last 50 years, with an excellent survival rate of more than 20 years. However, hip instability, impingement, dislocation, and liner wear remain common causes of THA failure and revision after THA. To minimize the risk of postoperative complications, abnormal spine-pelvic-hip mobility and its impact on THA outcomes have received increasing attention. According to the concept, the patient's pelvic mobility should be fully considered when making preoperative plans for THA. Individualized anteversion and inclination angles should be set according to the patient's sagittal balance and pelvic mobility to reduce the incidence of postoperative adverse events and prolong the life of the prosthesis. In the literature, recent studies have shown that patient aging, postural changes in daily life, high body mass index (BMI), and different surgical approaches and positions can impact spinopelvic mobility. Because changes in pelvic mobility translate into changes in acetabular orientation, excessive intraoperative or postoperative changes in pelvic mobility may result in poor intraoperative prosthesis orientation, postoperative impingement, dislocation, and accelerated liner wear, ultimately shortening the life of the prosthesis. Therefore, it is vital to evaluate and measure spinopelvic mobility preoperatively, investigate the factors that influence intraoperative pelvic mobility changes and the use of assisted positioning devices for accurate cup placement, and observe postoperative changes in pelvic mobility and the resulting adverse outcomes. This review takes the current literature on the spine-pelvic-hip interrelationship as a starting point and presents studies on the factors influencing spinopelvic mobility and the strategies for perioperative management of THA.
