BACKGROUND:At present,there are few reports on the postoperative efficacy of arthroscopic coracoid tunnel-free suspension fixation and coracoid single tunnel fixation in the treatment of acromioclavicular joint dislocation at home and abroad.The specific clinical efficacy of the two procedures and whether there are other risks need to be explored. OBJECTIVE:To compare the short-term postoperative clinical efficacy of arthroscopic TightRope band plate fixation with single tunnel fixation of the coracoid process and tunnel-free suspension fixation of the coracoid process in the treatment of acute type Ⅲ-Ⅴ acromioclavicular joint dislocation. METHODS:A retrospective analysis was performed in 45 patients with acromioclavicular joint dislocation who met the inclusion criteria admitted to the Sixth Affiliated Hospital of Xinjiang Medical University from June 2019 to September 2022,and were divided into coracoid single tunnel fixation group(20 cases)and coracoid tunnel-free suspension fixation group(25 cases)according to the surgical treatment plan.Operation time,incision length,blood loss,Constant-Murley score,visual analogue scale score,the American Shoulder and Elbow Surgeons(ASES)score and intraoperative and postoperative complications of the shoulder joint before operation,3 months after surgery and the last follow-up were compared between the two groups. RESULTS AND CONCLUSION:All patients successfully completed the operation,and there was no important nerve or blood vessel damage during the operation.The operation time of the coracoid tunnel-free suspension fixation group was significantly shorter than that of the coracoid tunnel-free suspension fixation group(P<0.05).There was no significant difference in intraoperative blood loss and incision length between the two groups(P>0.05).All patients were followed up for 12 to 24 months,with an average of(15.29±2.73)months.In the coracoid single tunnel fixation group,at 3 months after operation and the final follow-up,the visual analogue scale score was significantly lower than the preoperative score(P<0.05);Constant-Murley score and ASES score were significantly increased compared with the preoperative values(P<0.05).In the coracoid tunnel-free suspension fixation group,at 3 months after operation and the final follow-up,the visual analogue scale score was significantly lower than the preoperative score(P<0.05);the Constant-Murley score and the ASES score were both significantly higher than the preoperative scores(P<0.05).At 3 months after operation,the Constant-Murley score of the coracoid tunnel-free suspension fixation group was higher than that of the coracoid single tunnel fixation group(P<0.05),while there was no significant difference in visual analogue scale and ASES scores between the two groups(P>0.05).There was also no significant difference in the visual analogue scale,Constant-Murley,and ASES scores between the two groups at the corresponding time points before surgery and at the final follow-up(P>0.05).Intraoperative and postoperative complications:In the coracoid single tunnel fixation group,there was one case of coracoid cortical rupture and fracture during the tunnel drilling during the operation,and one case of a loss of reduction at 3 months after operation,which was repositioned and fixed with hook plate transposition of the coracoacromial ligament.All patients had good acromioclavicular joint function recovery and no re-dislocation at the final follow-up.All patients in the coracoid tunnel-free suspension fixation group did not suffer from coracoid fractures,loss of reduction and other complications during surgery,postoperatively and at the last follow-up.To conclude,these two arthroscopic treatments for acute type Ⅲ-Ⅴ acromioclavicular joint dislocation have the advantages of less trauma,reliable reduction and fixation,and good recovery of shoulder joint function after operation.However,compared with the coracoid single tunnel technique,the coracoid tunnel-free suspension fixation requires shorter time,faster recovery of shoulder joint function in the short term,and avoids the establishment of bone tunnels on the coracoid process,which reduces the probability of iatrogenic fracture of the coracoid process during operation and provides a higher degree of safety.
2.Research progress on the treatment of inflammatory bowel disease with sphingosine-1-phosphate receptor modulators
China Pharmacy 2025;36(7):881-886
Inflammatory bowel disease (IBD), a chronic gastrointestinal inflammatory disorder, is currently limited by conventional therapies due to its lack of specificity and pronounced drug resistance. Sphingosine-1-phosphate receptor (S1PR) modulators, as novel precision therapeutic agents, demonstrate promising efficacy in IBD treatment. This review synthesizes the mechanistic insights and recent advances in the treatment of IBD with S1PR. Our analysis reveals that S1PR modulators suppress intestinal inflammatory responses through three core mechanisms: regulating lymphocyte migration, inducing receptor degradation, and exerting subtype-specific S1PR modulation. Currently, Ozanimod and Etrasimod have been approved for IBD treatment, while Amiselimod, KRP-203, Fingolimod and Ceralifimod are not approved for clinical use, but have shown great potential for IBD disease.

The development of organ transplantation has brought new hope to many patients with organ failure and their families, but it has also raised numerous ethical issues. How to balance the rights and interests between organ donors and recipients, as well as ensure the fairness and transparency of the transplantation process has become an urgent problem to be solved. Based on the latest Regulations on Organ Donation and Transplantation and the Working Rules of the Ethics Committee for Human Organ Transplantation, the current difficulties and challenges in organ transplantation ethics were deeply analyzed. Taking the ethical review practice of Shenzhen Third People’s Hospital as an example, this paper explored issues such as full informed consent of both donors and recipients, risk assessment of marginal donors, and the review of relationships between donors and recipients. It also explored and constructed a set of complete ethical review models for organ transplantation through refined management. This model improved the efficiency and quality of ethical review as well as enriched the related knowledge system. It is expected that the implementation of this model can provide a reference for promoting effective ethical review nationwide, advancing the improvement and development of ethical review work in organ transplantation. Meanwhile, more medical ethics experts and practitioners are called upon to focus on and engage in the research and practice of ethical review in organ transplantation, jointly promoting progress in this field.

ObjectiveTo explore the mechanism of action of Wendantang on ApoE-/- hyperlipidemic mice using non-targeted metabolomics technology. MethodsMale C57BL/6J mice served as the normal control group (n=6), and they were fed with regular chow, while male ApoE-/- mice constituted the high-fat group (n=30), and they were fed with a 60% high-fat diet. After 11 weeks of model establishment, the mice in the high-fat group were randomly divided into the model group, simvastatin group (3.3 mg·kg-1), and high-dose, medium-dose, and low-dose groups of Wendantang (26, 13, 6.5 g·kg-1, respectively, in terms of crude drug amount), with six mice in each group. The normal control group and the model group were gavaged with an equivalent volume of normal saline, and all groups continued to be fed their respective diets, receiving daily medication for 10 weeks with weekly body weight measurements. Serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), free fatty acids (NEFA), blood glucose (GLU), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected in the mice. Pathological changes in liver tissue were observed using hematoxylin-eosin (HE) staining, and ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) was employed for metabolomic analysis of mouse liver tissue. ResultsCompared to the normal control group, the model group exhibited significantly increased body weight, blood lipid levels, and liver function (P<0.05, P<0.01), with disordered liver tissue structure, swollen hepatocytes, and accompanying vacuolar fatty degeneration and inflammatory cell infiltration. Compared to the model group, the simvastatin group and Wendantang groups showed significantly reduced body weight, TG, NEFA, GLU, ALT, and AST levels (P<0.05, P<0.01), with a significant increase in HDL-C levels (P<0.05, P<0.01), demonstrating a dose-dependent effect. The lesion of the liver tissue section was obviously improved after administration, tending towards a normal liver tissue morphology. Analysis of liver metabolites revealed 86 differential metabolites between the normal control group and the model group, with the high-dose group of Wendantang able to regulate 56 of these metabolites. Twenty-two differential metabolites associated with hyperlipidemia were identified, mainly including chenodeoxycholic acid, hyocholic acid, taurine, glycocholic acid, dihydroceramide, hydroxy sphingomyelin C14∶1, arachidonic acid, and linoleic acid, enriching 22 metabolic pathways, with 4 being the most significant (P<0.05), namely primary bile acid biosynthesis, sphingolipid metabolism, unsaturated fatty acid biosynthesis, and linoleic acid metabolism pathways. ConclusionWendantang can improve blood lipid levels and liver function in ApoE-/- hyperlipidemic mice, which may be related to the regulation of primary bile acid biosynthesis, sphingolipid metabolism, unsaturated fatty acid biosynthesis, and linoleic acid metabolism pathways.

OBJECTIVE To provide suggestions for improving the path and system construction of patient engagement in drug regulation in China. METHODS By reviewing initiatives and experiences from the United States (U. S.), European Union (EU), and Japan in promoting patient engagement, this study summarizes the roles and contributions of patients in the entire drug regulatory process internationally. Combining China’s current progress and challenges in patient engagement, specific proposals are formulated to refine regulatory pathways and institutional systems. RESULTS & CONCLUSIONS With growing global emphasis on patient engagement as a regulatory strategy, countries or regions such as the U.S., EU, and Japan have established clear policies, designated oversight agencies, and developed diversified pathways for patient engagement. Patients contribute to regulatory processes through advisory meetings, direct decision-making roles, and leveraging lived experiences and expertise to optimize drug evaluation and monitoring. In contrast, China’s patient engagement remains primarily limited to clinical value- oriented drug development, lacking formal policy guidance. It is recommended that China, based on its existing policy system, further strengthen the construction of a safeguard system for patient engagement, improve the capacity building and pathway models for patient participation in pharmaceutical regulation, and promote the continuous development of patient engagement in pharmaceutical regulation in our country.

OBJECTIVE To explore the effects of isorhamnetin on the development of gastric cancer through up-regulation of solute carrier family 25 member 25 antisense RNA 1(SLC25A25-AS1). METHODS Using BALB/c nude mice as the subjects, the xenograft tumor model was established by subcutaneously inoculating human gastric cancer MKN28 cells into the axillary region. The effects of low and high doses of isorhamnetin (20 and 40 mg/kg) on the tumor volume and mass in nude mice were investigated. MKN28 cells were selected and divided into control group, isorhamnetin group (70 μmol/L, similarly hereinafter), isorhamnetin+knocking down negative control group, isorhamnetin+knocking down SLC25A25-AS1 group, isorhamnetin+ overexpression negative control group and isorhamnetin+overexpressing SLC25A25-AS1 group. Effects of knocking down/ overexpressing SLC25A25-AS1 on viability, apoptosis, migration and invasion ability of isorhamnetin-treated cells were detected. After verifying the targeting relationships between microRNA-212-3p (miR-212-3p) and SLC25A25-AS1, as well as phosphatase and tensin homologue deleted on chromosome 10 (PTEN), the effects of knocking down/overexpressing SLC25A25-AS1 on the expression of miR-212-3p, PTEN mRNA, and PTEN protein in isorhamnetin-treated cells were investigated. RESULTS Compared with the model control group, tumor volume and mass of nude mice in the isorhamnetin low-dose and high-dose groups were reduced significantly, and the isorhamnetin high-dose group was significantly lower than the isorhamnetin low-dose group (P<0.05). miR-212-3p had targeting relationships with SLC25A25-AS1 and PTEN. Compared with the control group, the cell viability (intervened for 24, 48 h), migration number, invasion number and miR-212-3p expression of cells in the isorhamnetin group, isorhamnetin+knocking down negative control group and isorhamnetin+overexpressing negative control group were significantly reduced or decreased or down-regulated, while the apoptosis rate, mRNA and protein expressions of PTEN were significantly increased or up-regulated (P<0.05). Compared with isorhamnetin group and isorhamnetin+knocking down negative control group, the cell viability, migration number, invasion number and miR-212-3p expression of cells in the isorhamnetin+knocking down SLC25A25-AS1 group were significantly increased or up- regulated, while the apoptosis rate, mRNA and protein expressions of PTEN were significantly reduced or down-regulated (P< 0.05). Compared with isorhamnetin group and isorhamnetin+overexpressing negative control group, the cell viability, migration number, invasion number and miR-212-3p expression of cells in isorhamnetin+overexpressing SLC25A25-AS1 group were significantly reduced or decreased or down-regulated, while the apoptosis rate, PTEN mRNA and protein expressions were significantly increased or up-regulated (P<0.05). CONCLUSIONS Isorhamnetin may inhibit the development of gastric cancer by up-regulating the expression of SLC25A25-AS1, down-regulating miR-212-3p, and up-regulating the expression of PTEN, which is a downstream target of miR-212-3p.

OBJECTIVE To analyze the standardization and influential factors medication use for the prevention and treatment of glucocorticoid-induced osteoporosis (GIOP). METHODS The data of inpatients diagnosed as rheumatic immune diseases in our hospital from January 1, 2022, to December 31, 2023, who required long-term use of glucocorticoids, were collected to analyze the risk stratification for GIOP-related fractures and the utilization of prevention and treatment drug in patients. Univariate analysis and Logistic stepwise regression analysis were employed to screen the factors influencing the standardization of prevention and treatment drug use in patients. RESULTS Among 354 patients, 148 patients (41.81%) had a low risk of osteoporotic fractures, 103 patients (29.10%) had a moderate risk, and 103 patients (29.10%) had a high risk. The top three drugs used in the prevention and treatment of GIOP were calcium supplements (78.81%), vitamin D preparations (74.01%), and anti-osteoporosis drugs (21.19%). A total of 133 patients (37.57%) used the drugs for GIOP prevention and treatment in a standardized manner. The standardization rate of prevention and treatment in patients with low fracture risk was significantly higher than those with high and moderate fracture risk, and the standardization rate in patients with high fracture risk was significantly higher than those with moderate fracture risk (P<0.05). Besides, the univariate analysis showed that low fracture risk served as a prevention factor for the standardized use of prevention and treatment drugs for GIOP, while moderate fracture risk, smoking or drinking, the occurrence of adverse drug reactions, and having an educational level below junior college were risk factors for the normative use of GIOP prevention and treatment drug (P<0.05). Logistic stepwise regression analysis showed that patients with low and moderate fracture risk, a history of smoking or drinking, and adverse drug reactions to anti-osteoporosis drugs had a lower standardization rate of prevention and treatment; patients who visited tertiary hospital for the past month and had a longer duration of glucocorticoid use had a higher standardization rate of prevention and treatment (P<0.05). CONCLUSIONS The standardized rate of prevention and treatment drugs used for GIOP in our hospital is relatively low. Patients with moderate to high fracture risk, a history of smoking or drinking, and those who experience adverse drug reactions after taking anti-osteoporosis drugs have lower rates of standardized prevention and treatment. Conversely, patients who sought treatment at tertiary hospital for the past month and had a longer duration of glucocorticoid had higher rates of standardized prevention and treatment.

Background The neck, shoulders, and lower back are the primary affected areas of work-related musculoskeletal disorders. In manual tasks, combinations of hand functional height (defined as working height below the waist), awkward postures, and cognitive load are common risk factors. However, there is limited literature documenting how these factors specifically alter biomechanical load on the neck, shoulders, and lower back when working at hand functional height. Objective To explore quantitative differences in biomechanical load on the neck, shoulders, and lower back of workers performing manual tasks at hand functional height under different postures and cognitive load combinations. Methods A 3x2 within-subject design was implemented, with three postures (squat, kneeling, and stoop) and two levels of cognitive load (with cognitive load induced by a 2back task and without cognitive load). Ten male university students were recruited to perform a predetermined assembly task (a sequence of loosening and tightening screws) at hand functional height. Surface electromyography (sEMG) and 3D motion capture system were employed to assess the participants’ trunk biomechanical load in executing the tasks. Additionally, subjective perception, including fatigue, muscle pain, and cognitive load, were evaluated using scales. Results Significant variations in biomechanical load were observed across the three postures (P<0.05). The stoop posture exhibited the lowest muscle activation in most target muscles, except for the sternocleidomastoid, and showed the fastest decline in instantaneous median frequency (IMF) of the erector spinae, with a rate of (-0.050±0.008) Hz per unit time (0.128 s), and the greatest trunk flexion angle (35.14°±4.40°). Performing the task by squatting resulted in the highest muscle activation, especially in the upper trapezius, where maximum voluntary contraction percentage reached 20.07%±1.26%. In addition, the squatting posture also resulted in larger joint angles in the sagittal plane for the neck (−7.03°±2.70°), shoulders (60.20°±7.89°), and lower back (34.42°±4.20°). The kneeling posture showed intermediate muscle activation, the slowest IMF decline for the erector spinae in the lower back (−0.005±0.008) Hz per unit time (0.128s), and the joint angles were closest to neutral. The task performance results were also superior in the kneeling posture. Regarding cognitive load, no significant differences were found for most biomechanical indicators, except for subjective cognitive load scores, neck flexion, and shoulder external rotation angles. Conclusion In assembly tasks performed at hand functional height, kneeling results in moderate biomechanical load on the neck, shoulders, and lower back while also improves task performance compared to squatting and forward bending. Additionally, no significant effects of cognitive load under the 2back condition on biomechanical load are observed.

The interleukin-10 (IL-10) family is expressed in various types of cells and has a wide range of biological functions, and it plays an important role in the development and progression of hepatic fibrosis. Hepatic fibrosis is a chronic liver disease characterized by abnormal repair of hepatic tissues after injury, activation of hepatic stellate cells, and excessive accumulation of extracellular matrix. The IL-10 family members include IL-10, IL-19, IL-20, IL-22, IL-24, IL-26, IL-28, IL-29, and IL-35, with similarities in structure and function, and changes in their expression levels are closely associated with the progression of hepatic fibrosis. Moderate upregulation of the expression of IL-10 family members can help maintain the quiescent state of hepatic stellate cells, promote the transformation of macrophages to anti-inflammatory phenotype, and regulate the activity of natural killer cells, thereby inhibiting inflammatory response, regulating cell apoptosis and autophagy, and finally reversing the progression of hepatic fibrosis. This article discusses the mechanism of action of IL-10 family members and their application in traditional Chinese medicine and Western medicine therapies, in order to provide new thoughts for the treatment of hepatic fibrosis.

Objective To evaluate the value of an optimized three-dimensional inversion-recovery with real reconstruction (3D-real IR) sequence with a longer repetition time (TR, 16 000 ms) based on modulated flip angle technique in refocused imaging with extended echo train (MATRIX) in the endolymphatic hydrops (EH) imaging after intratympanic gadolinium (Gd) administration, and to compare it with a conventional 3D-real IR based on the turbo spin echo (TSE) sequence. Methods From July 2021 to November 2022, twenty-seven patients received both the conventional and optimized 3D-real IR sequences after bilateral intratympanic Gd administration. Images of the two sequences were qualitativly evaluated and compared. Contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR), and area ratio of endolymph against the total lymphatic space from the two sequences were measured and compared. Results 14(25.9%) ears with insufficient contrast for the EH diagnosis on the conventional sequence were clearly displayed on the optimized sequence. Image score, CNR and SNR of the optimized sequence were significantly higher than those of the conventional sequence (P < 0.001). The scanning time of two sequences was similar. The area ratio of endolymph against the total lymphatic space in the cochlear was significantly higher on the conventional 3D-real IR than that on the optimized 3D-real IR (P < 0.001); there was no statistical difference in the vestibule between the two sequences. Conclusions Compared with conventional sequence, optimized 3D-real IR sequence with a longer TR may be better for evaluation of EH after intratympanic Gd administration.
