Prostate cancer is one of the most common malignant tumors of male genitourinary system. Prostate cancer has the following characteristics: insidious onset, early asymptomatic or not obvious symptoms, complex etiology and pathogenesis, long incubation period and so on. Therefore, the realization of its early diagnosis and treatment is of great significance to the prognosis of patients. Prostate-specific membrane antigen (PSMA) is a type 2 transmembrane glycoprotein that is highly expressed on the membrane of almost all primary and metastatic prostate cancer cells, and is an ideal target for prostate cancer imaging and treatment. In recent years, with the approval of urea-containing small molecule PET (positron emission computed tomography) radiopharmaceutical based on PSMA (68Ga-PSMA-11, 18F-PSMA-1007), PET-CT (positron emission computed tomography/computed tomography) has shown new potential for early diagnosis and accurate staging of prostate cancer patients. This review mainly summarizes the research progress of urea-containing PSMA PET imaging agents and finds that they have defects such as uptake in non-target tissues like the kidneys, lacrimal glands, and salivary glands. Thus, further optimizing their structure to reduce the uptake in non-target tissues, providing provide convenience for the labeling of therapeutic radiopharmaceuticals, thereby achieving the goal of integrated diagnosis and treatment, is an important development direction in this field.

ObjectiveTo investigate the optimal termination time for acupuncture in treating patients with acute peripheral facial paralysis and its cost-effectiveness. MethodsA total of 120 eligible patients with acute-stage peri-pheral facial paralysis were randomly assigned to either the mild dysfunction termination group and the complete recovery termination group, with 60 patients in each group. Both groups received the standard acupuncture treatment protocol. Treatment in the mild dysfunction termination group was terminated when the Sunnybrook facial grade scale (SFGS) score first reached or exceeded 83 points, while that in the complete recovery termination group was terminated when the SFGS score first reached or exceeded 95 points. Assessments were conducted before treatment, 6 and 12 months after onset. SFGS, facial disability index (FDI) including physical function (FDIp) and social function (FDIs), self-rating anxiety scale (SAS), and self-rating depression scale (SDS) scores were assessed before treatment, and 6 and 12 months after onset. Any acupuncture-related adverse events during treatment were recorded for safety evaluation. Treatment sessions and medical costs including direct costs, indirect costs, insurance coverage, total societal costs, and patient out-of-pocket expenses were also recorded, and an economic evaluation was conducted including cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER). ResultsUltimately, 56 patients in the mild dysfunction termination group and 55 in the complete recovery termination group completed the follow-up. At 6 and 12 months after onset, SFGS and FDIp scores in both groups improved significantly while FDIs, SAS and SDS scores decreased (P<0.05). Comparison of scores between groups 6 months and 12 months after onset showed no statistically significant differences (P>0.05). During the trial, the incidence of adverse events was 13.3% (8/60) in the mild dysfunction termination group and 18.3% (11/60) in the complete recovery termination group, with no statistically significant difference (P>0.05). The number of treatment sessions, total social costs, and out-of-pocket expenses in the mild dysfunction termination group were significantly lower than those in the complete recovery termination group (P<0.05). The CER of the mild dysfunction termination group in SFGS, FDIp, FDIs, SAS, and SDS scores was lower than that of the complete recovery termination group. The ICER analysis showed that continuing treatment until full recovery incurred an additional cost of 573.30 CNY/point in SFGS improvement, whereas 1-point improvement in FDIp, FDIs, SAS, and SDS required 21,355.25 CNY, 1779.60 CNY, 3713.96 CNY, and 2755.52 CNY, respectively. ConclusionFor acupuncture in treating acute peripheral facial palsy, terminating treatment when mild dysfunction is achieved yields long-term efficacy comparable to that of continuing treatment until complete recovery, while significantly reducing medical costs and socioeconomic burden.

PURPOSE:
To assess the relationship between dislocation and functional outcomes in supination-external rotation (SER) ankle fractures.
METHODS:
A retrospective case series study was performed on patients with ankle fractures treated surgically at a large trauma center from January 2015 to December 2021. The inclusion criteria were young and middle-aged patients of 18 - 65 years with SER ankle fractures that can be classified by Lauge-Hansen classification and underwent surgery at our trauma center. Exclusion criteria were serious life-threatening diseases, open fractures, fractures delayed for more than 3 weeks, fracture sites ≥ 2, etc. Then patients were divided into dislocation and no-dislocation groups. Patient demographics, injury characteristics, surgery-related outcomes, and postoperative functional outcomes were collected and analyzed. The functional outcomes of SER ankle fractures were assessed postoperatively at 1-year face-to-face follow-up using the foot and ankle outcome score (FAOS) and American Orthopedic Foot and Ankle Society ankle hindfoot score and by 2 experienced orthopedic physicians. Relevant data were analyzed using SPSS version 22.0 by Chi-square or t-test.
RESULTS:
During the study period, there were 371 ankle fractures. Among them, 190 (51.2%) were SER patterns with 69 (36.3%) combined with dislocations. Compared with the no-dislocation group, the dislocation group showed no statistically significant differences in gender, age composition, fracture type, diabetes, or smoking history, preoperative waiting time, operation time, and length of hospital stay (all p > 0.05), but a significantly higher Lauge-Hansen injury grade (p < 0.001) and syndesmotic screw fixation rate (p = 0.033). Moreover, the functional recovery was poorer, revealing a significantly lower FAOS in the sport/rec scale (p < 0.001). Subgroup analysis showed that among SER IV ankle fracture patients, FAOS was much lower in pain (p = 0.042) and sport/rec scales (p < 0.001) for those with dislocations. American Orthopedic Foot and Ankle Society ankle hindfoot score revealed no significant difference between dislocation and no-dislocation patients.
CONCLUSION
Dislocation in SER ankle fractures suggests more severe injury and negatively affects functional recovery, mainly manifested as more pain and poorer motor function, especially in SER IV ankle cases.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.

The development and validation of clinical prediction models based on artificial intelligence (AI) and machine learning methods have become increasingly widespread. However, the prediction model bias risk and applicability evaluation tool developed in 2019 (i.e., PROBAST-2019) has shown significant limitations. Therefore, an expanded and updated version of the PROBAST-2019 tool was released in 2025, known as the PROBAST+AI tool. The tool is divided into two parts including model development and model evaluation. It aims to comprehensively and systematically evaluate potential methodological quality issues in model development, bias risks in model evaluation, and the applicability of models, regardless of the modeling method used. This paper provides a systematic interpretation of the PROBAST+AI tool's items and case analyses, with the aim of guiding and assisting researchers engaged in related studies and promoting the high-quality development of clinical predictive model research.

A self-supervised super-resolution reconstruction method based on scale adaptive and coordinate encoding is proposed to realize super-resolution reconstruction of anisotropic brain magnetic resonance images with different slice thicknesses even in the absence of paired isotropic brain magnetic resonance images.Firstly,an image encoding module that integrates super-resolution scale information is used to learn the specific features of images with different slice thicknesses.Subsequently,a coordinate encoding module is employed to facilitate the deep fusion of coordinate information and image features.Finally,an overall loss function comprising reconstruction loss and brain tissue edge perception loss is adopted to optimize the recovery of edge high-frequency information,while global residual learning is introduced to enhance network training.Experimental results on the HCP-1200 and OASIS-1 datasets demonstrate that the proposed method outperforms other self-supervised super-resolution reconstruction methods.

Objective To clarify the effect of preoperative oral carbohydrate on overweight or obese patients undergoing laparoscopic hysterectomy in Trendelenburg position.Methods A total of 72 overweight or obese patients who underwent laparoscopic hysterectomy in Trendelenburg position at Yancheng Third People's Hospital from September 2022 to August 2024 were selected,and randomly divided into the control group and the observation group,with 36 cases in each group.The control group received routine restriction of fasting and fluid starting from 22:00 on the day before surgery,while the observation group was given an additional 300 mL of carbohydrate orally 2 hours before anesthesia on the basis of the control group.The preoperative ultrasound results of gastric antrum,Perlas classification,full stomach status,visual analogue scale(VAS)scores for thirst and hunger,awakening time,tracheal extubation time,intraoperative hypothermia,gastro-intestinal function recovery time,and adverse reactions were compared between the two groups.Results Before anesthesia,there was no statistically significant difference in the cross-sectional area of the gastric antrum(CSA)in the right lateral position,gastric volume(GV),or the ratio of gastric volume to body weight(GV/W)between the two groups(P>0.05).There was also no statistically significant difference in the Perlas classification of gastric antrum ultrasound or the incidence of full stomach between the two groups(P>0.05).Immediately before anesthesia,the VAS scores for thirst and hunger in the observation group were significantly lower than those in the control group(P<0.05).The awakening time,tracheal extubation time,and incidence of intraoperative hypothermia in the observation group were significantly shorter/lower than those in the control group(P<0.05).The observation group had significantly shorter time of first exhaust and defecation after surgery,as well as lower incidence of postoperative bloating,compared with the control group(P<0.05).Conclusion For overweight or obese patients undergoing laparoscopic hysterectomy in the Trendelenburg position,oral intake of 300 mL carbohydrate 2 hours before anesthesia does not increase the risk of regurgitation or aspiration,with safety and reliability.It not only can improve comfort of patients and promote post-anesthesia awakening,but also can reduce the incidences of intraoperative hypothermia and gastrointestinal adverse reactions,which is conducive to accelerating postoperative recovery.
