Objective:To compare the therapeutic efficacy, safety and drug cost between generic enteric-coated mycophenolate sodium (EC-MPS) and branded EC-MPS in immunosuppressive treatment for adult recipients of renal transplantation (RT) .Methods:From January, 2022 to October, 2023, 60 adult RT patients were continuously enrolled and randomized into two groups. Patients receiving generic EC-MPS were selected as cohort 1 (n=30) while those taking branded EC-MPS designated as cohort 2 (n=30). Hepatic/renal function, blood routine parameters, drug concentrations, adverse events (AEs) and drug costs were recorded and compared between two cohorts at baseline (<3 days before/after day of RT, W0), week 1 (W1), week 4 (W4), week 8 (W8), week 12 (W12) and week 24 (W24) post-RT.Results:Only urine protein was elevated at W24[0.4 (0-0.6) vs 0 (0-0.2) g/24 h, P=0.049]in cohort 1 as compared with cohort 2. Aspartate aminotransferase at W12 (15.6±3.3 vs 20.3±9.7 U/L, P=0.010), leucocyte count at W1 (8.4±2.3 vs 10.1±3.8 ×10 9/L, P=0.045) and platelet count at W1 (158.5±51.5 vs 185.8±46.8 ×10 9/L, P=0.036) all declined in cohort 1 as compared with cohort 2. However, these parameters at other timepoints did not vary between two cohorts (all P>0.050). In addition, blood concentration of MPS after dosing, area under the concentration-time curve and trough concentration of tacrolimus at different timepoints were not different between two cohorts (all P>0.050). Similarly, helper T cells (Th), suppressor T cells (Ts), Th/Ts and B cells at W4/12 did not vary between two cohorts (all P>0.050). Concerning drug cost, no difference existed in the number of tablets or length of stay between two cohorts (both P>0.050). However, cost of EC-MPS (￥1 333.5±419.6 vs ￥2 368.6±596.0, P<0.001) and total cost during hospitalization (￥96 403.3±29 159.8 vs ￥117 062.8±28 782.1, P=0.001) were lower in cohort 1 than cohort 2. The most common AEs in cohort 1 included acid regurgitation (n=19, 63.3%), hypoalbuminemia (n=16, 53.3%), anemia (n=12, 40.0%) and hypokalemia (n=11, 36.7%). And the most common AEs in cohort 2 included acid regurgitation (n=20, 66.7%), anemia (n=14, 46.7%) and hypoalbuminemia (n=9, 30.0%). Notably, the incidence of all AEs was not different between two cohorts (all P>0.050) . Conclusion:Generic EC-MPS has comparable therapeutic efficacy and safety profile with lower drug cost in adult RT patients. It provides more options for maintenance treatment in RT patients.

Objective:To investigate the response of mandibular condylar chondroprogenitors to flow fluid shear stress(FFSS).Methods:Chondroprogenitors were in vitro cultured and stimulated with FFSS that can cause cell degeneration,and treated with sec-ond-generation high-throughput RNA sequencing.Differential gene expression was screened using DESeq2 software for gene ontology(GO)functional enrichment analysis,kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis and protein-protein interaction(PPI)network analysis.qRT-PCR was performed to validate the core genes screened by PPI.Results:A total of 1996 differentially expressed genes were obtained,mainly including inflammatory response and cell cycle related molecules.Among them,Actal,Atf3,Ccl2,116,Nfkbia,Ret and Vcaml were identified as the core genes.Conclusion:FFSS stimulation affects chondroprogenitor function by acting on inflammatory responses and cell cycle-related signaling pathways in chondroprogenitors.

BACKGROUND:Traditional 3D dental segmentation methods usually utilize predefined spatial geometric features,such as curvature and normal vectors,as the reference information for tooth segmentation. OBJECTIVE:To propose an algorithm for complex 3D dental segmentation and deeply explore the correlation between segmentation results and application scenarios. METHODS:A 3D dental segmentation algorithm based on dual stream extraction of structural features and spatial features was established,and the modular design of split flow was used to avoid feature confusion.Among them,the attention mechanism on the structural feature flow was used to capture the fine-grained semantic information required for tooth segmentation,and the Tran Net based on the spatial feature flow was used to ensure the robustness of the model to complex tooth and jaw segmentation.This algorithm verified its effectiveness and reliability based on clinical datasets including healthy dental jaws and complex dental jaws such as missing teeth,malocclusion and dentition crowding.The segmentation performance of the model was measured in terms of overall accuracy,mean intersection over union,and directional cut discrepancy. RESULTS AND CONCLUSION:The overall segmentation accuracy of this algorithm in the clinical data set is 97.08%,and the segmentation effect is superior to that of other competitive methods from the qualitative and quantitative perspectives.It is verified that the structural feature flow designed in this paper can extract more precise local details of tooth shape from coordinate and normal information by constructing an attention aggregation mechanism,and the spatial feature flow designed in this paper can ensure the robustness of the model to complex teeth such as missing teeth,dislocated teeth,and crowded dentition by constructing a transformation network(Tran Net).Therefore,this tooth segmentation algorithm is highly reliable for clinicians'practical reference.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objectives:To report the sexual functional outcomes of vaginal dilation therapy in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome patients.Methods:From March 2020 to February 2023, 97 MRKH syndrome patients performed vaginal dilation therapy with guidance from Peking Union Medical College Hospital, and 45 of them engaged in penetrative intercourse and were included in this prospective cohort study. The Chinese version of female sexual function index (FSFI) was used to assess sexual function. Functional success was defined as FSFI>23.45. Forty age-matched healthy women were selected as controls. Kaplan-Meier survival analysis was used to calculate the median time to success. Pearson correlation analysis was used to explore the relationship between neovagina length and sexual function. Complications were collected using follow-up questionnaires.Results:The functional success rate of vaginal dilation therapy was 89% (40/45) with a median time to success of 4.3 months (95% CI: 3.0-6.1 months). Compared to controls, MRKH syndrome patients had significantly lower scores in the orgasm domain (4.72±1.01 vs 4.09±1.20; P=0.013) and pain domain (5.03±0.96 vs 4.26±0.83; P<0.001). However, there were no significant differences in the FSFI total score (26.77±2.70 vs 26.70±2.33; P=0.912), arousal domain (4.43±0.77 vs 4.56±0.63; P=0.422) and satisfaction domain (4.88±0.98 vs 4.65±0.86; P=0.269) between MRKH syndrome patients and controls. MRKH syndrome patients had significantly higher scores in the desire domain (3.33±0.85 vs 3.95±0.73; P<0.001) and lubrication domain (4.37±0.56 vs 5.20±0.67; P<0.001). The prevalence of sexual dysfunction in MRKH patients was non-inferior to controls: low desire [3% (1/40) vs 23% (9/40); P=0.007], arousal disorder [3% (1/40) vs 3% (1/40); P>0.999], lubrication disorder [5% (2/40) vs 25% (10/40); P=0.012], orgasm disorder [40% (16/40) vs 20% (8/40); P=0.051], sexual pain [30% (12/40) vs 15% (6/40); P=0.108]. Conclusions:MRKH syndrome patients undergoing non-invasive vaginal dilation therapy could achieve satisfactory sexual life. Given its high functional success rate and slight complication, vaginal dilation therapy should be recommended as the first-line option, reducing the need for unnecessary surgeries.

Conclusion:Generic EC-MPS has comparable therapeutic efficacy and safety profile with lower drug cost in adult RT patients. It provides more options for maintenance treatment in RT patients.

Mood disorders are a group of mental conditions characterized by significant and lasting mood or emotional changes, which seriously affect patients′ normal lives. However, the pathogenesis of mood disorders is still unclear, and the specific biological markers to assist the diagnosis are still not determined, and this affects the diagnosis, treatment and prognosis. With the development of molecular imaging, positron emission tomography (PET) has been widely used in clinical research on mood disorders, which is helpful for their clinical diagnosis and treatment. This paper aims to review the research progress on PET imaging principles, the pathogenesis and treatment mechanism of mood disorders, and to summarize the application prospect of PET in mood disorders.

Objective:To investigate the characteristics of digestive system symptoms and its relation with the time of nucleic acid continuous positive in population infected with severe acute respiratory syndrome coronavirus 2 Omicron variant, and to analyze the abdominal computed tomography (CT) features of patients infected with Omicron variant.Methods:From April 11 to May 23, 2022, a questionnaire survey was conducted in patients infected with Omicron variant admitted to the Shanghai National Convention and Exhibition Center Fangcang Hospital. The questionnaire included basic information, the start time of nucleic acid positive, respiratory symptoms, digestive system syptoms and outcomes, etc.Combined with the clinical data, the relation between digestive tract symptoms and the time of nucleic acid continuous positive were analyzed. Thoracic and abdominal CT were performed for patients with continuous positive nucleic acid results ≥10 d, and the relationship between the abdominal CT imaging characteristics and the time of nucleic acid continuous positive was analyzed. Independent sample t-test and multivariate logistic regression were used for statistical analysis. Results:A total of 4 360 valid questionnaires were collected, including 2 475 males and 1 885 females, with a hospital stay of (6.8±4.9) d. Among the 4 360 patients, 1 979 patients (45.4%) had gastrointestinal symptoms such as loss of appetite, abdominal discomfort or pain, constipation and diarrhea. The time of nucleic acid continuous positive in patients with gastrointestinal symptoms was (7.4±5.5) d, which was longer than that of patients without gastrointestinal symptoms (6.5±3.6) d, and the difference was statistically significant ( t=3.78, P<0.001). During the isolation period in the Fangcang Hospital, the time of nucleic acid continuous positive in patients with complete remission of digestive tract symptoms was shorter than that of patients with no remission of digestive tract symptoms ((7.3±5.2) d vs. (8.5±5.7) d), and the difference was statistically significant ( t=2.25, P=0.025). The results of multivariate logistic regression analysis showed that the combination of gastrointestinal symptoms was an independent risk factor for continuous positive nucleic acid result ≥10 d ( OR=1.316, 95% confidence interval 1.294 to 2.205, P=0.046). Among the 299 patients with continuous positive nucleic acid results≥10 d, 187 cases (62.5%) had gastrointestinal symptoms, and 146 cases (48.8%) had abdominal CT findings of thickening of the gastroduodenal wall, thickening of the small intestinal wall, indistinct mesenteric vessels of the small intestine, and dilatation and pneumatosis of the colon. In patients with continuous positive nucleic acid results ≥10 d, abdominal CT indicated that patients with gastrointestinal imaging changes had a longer time of nucleic acid continuous positive than those without gastrointestinal imaging changes ((16.0±2.8) d vs. (13.0±2.1) d), and the difference was statistically significant ( t=2.62, P=0.009). Conclusions:Digestive system symptoms are common in patients infected with Omicron variant. The time of nucleic acid continuous positive in patients with gastrointestinal symptoms is longer than those without gastrointestinal symptoms. Some patients may have gastrointestinal lesions on abdominal CT.
