Stroke ranks as the third leading cause of death and the fourth leading cause of disability worldwide. Its high disability rate and prolonged recovery period not only severely impact patients' quality of life but also impose a significant burden on families and society. Primary prevention is the cornerstone of stroke control, as early intervention on risk factors can effectively reduce its incidence. Therefore, the development of predictive models for first-ever stroke risk holds substantial clinical value. In recent years, advancements in big data and artificial intelligence technologies have opened new avenues for stroke risk prediction. This article reviews the current research status of traditional methods and machine learning models in predicting first-ever stroke risk and outlines future development trends from three perspectives: First, emphasis should be placed on technological innovation by incorporating advanced algorithms such as deep learning and large models to further enhance the accuracy of predictive models. Second, there is a need to diversify data types and optimize model architectures to construct more comprehensive and precise predictive models. Lastly, particular attention should be given to the clinical validation of models in real-world settings. This not only enhances the robustness and generalizability of the models but also promotes physicians' understanding of predictive models, which is crucial for their application and dissemination.
3.Expression and clinical significance of GINS2 in endometrial cancer tissues
Chinese Journal of Biologicals 2025;38(08):932-938
Objective To investigate the expression of GINS2 in endometrial cancer(EC) tissues and its correlation with prognosis.Methods The differential expression of GINS2 gene in EC and normal control tissues was analyzed using GEPIA,TIMER, and UALCAN databases. The endometrial tissues of 115 patients with EC(EC group), 30 patients with uterine fibroid(uterine fibroid group) and 26 patients with normal endometrium(normal control group) treated and followed up from May 2017 to December 2022 at the Department of Gynecology, Yunnan Cancer Hospital were collected. The transcription and translation levels of GINS2 gene in the samples were detected by qPCR and Western blot, respectively. Additionally, the expression levels and localization of GINS2 in different samples were analyzed using immunohistochemistry. Furthermore,the correlation between GINS2 expression levels and the clinicopathological features of EC was analyzed, and potential independent prognostic factors for EC were evaluated using Kaplan-Meier survival analysis and Cox proportional hazards regression model.Results The mRNA expression level of GINS2 gene was significantly higher in EC tissues than in normal control tissues according to all three databases(P < 0. 05). In the clinical validation cohort, both the transcriptional and protein expression levels of GINS2 gene were significantly higher in the EC group than in the uterine fibroid group and normal control group(t = 7. 707 and 8. 330, respectively, each P < 0. 01). GINS2 protein was mainly located in the cell nucleus and partially in the cytoplasm of EC tissues, with positive expression rates of 81. 74%, 46. 67% and 38. 46% in EC tissues,uterine fibroids, and normal endometrial tissues, respectively. GINS2 levels in EC tissues were associated with differentiation degree and lymph node metastasis(t = 4. 125 and 3. 589, respectively, each P < 0. 05), but not with age, tissue type, International Federation of Gynecology and Obstetrics(FIGO) stage, depth of invasion, estrogen receptor(ER) expression, or progesterone receptor(PR) expression(t = 0. 214, 0. 247, 0. 125, 0. 211, 0. 238, and 0. 314, respectively, each P > 0. 05). Multivariate Cox regression analysis showed that elevated GINS2 expression [hazard ratio(HR) = 2. 091, 95% confidence interval(CI): 1. 048-3. 135, P = 0. 019] and lymph node metastasis(HR = 1. 106, 95% CI: 1. 064-1. 149, P = 0. 027) were independent prognostic factors for EC patients.Conclusion The high expression of GINS2 in tissues is associated with poor prognosis of EC patients, and it is speculated that it may be related to the occurrence and development of EC.

Thyroid cancer is caused by multiple factors, including genetics, environment, metabolism, and the immune microenvironment, among which ionizing radiation exposure is an important risk factor for thyroid cancer. As one of the most sensitive target organs of ionizing radiation, the thyroid gland may have different risks of thyroid cancer caused by different types of ionizing radiation exposures, such as medical exposure, occupational exposure, and emergency exposure. The sensitivity of children and adolescents are higher than that of adults. The dose-response relationship still needs to be further explored. The molecular mechanism between ionizing radiation and the increased risk of thyroid cancer is complex, which may involve DNA damage and repair abnormalities, gene mutations, non-coding RNA regulation, DNA methylation, cell cycle regulation imbalance, and immune microenvironment changes. This article reviews the risk and molecular mechanisms associated with different types of ionizing radiation exposure in thyroid cancer, based on literature retrieved from CNKI and PubMed databases. It aims to provide a theoretical basis for the early monitoring, prevention, and intervention of thyroid cancer related to ionizing radiation exposure.

OBJECTIVE To compare the efficacy and safety of dupilumab versus thalidomide in the treatment of refractory prurigo nodularis (PN) in adults. METHODS A retrospective analysis was conducted on the clinical data of 123 adult patients with refractory PN admitted to Wuhan First Hospital from May 2021 to June 2024. Among them, 63 patients who received dupilumab comprised the observation group and 60 patients who received thalidomide comprised the control group. Clinical efficacy indicators [Investigator Global Assessment (IGA) score, Pruritus Numerical Rating Scale (P-NRS) score, Patient-Oriented Eczema Measure (POEM) score, and Dermatology Life Quality Index (DLQI) score], allergic biomarkers [eosinophil (EOS) count in peripheral blood and serum total immunoglobulin E (IgE) level], psychological scores [Hospital Anxiety and Depression Scale (HADS)] before and after treatment, as well as the occurrence of adverse drug reaction during treatment, were compared between the two groups. RESULTS Before treatment, there were no statistically significant differences between the two groups in above clinical efficacy indicators, allergic biomarkers, or psychological scores (P>0.05). At 4, 8, 12 and 16 weeks after treatment, both groups showed significant decreases in IGA score (except for the control group 4 weeks after treatment), IGA activity score (except for the control group 4 weeks after treatment), P-NRS score, POEM score, DLQI score (except for the control group 4 weeks after treatment), serum EOS count, and serum total IgE level compared with baseline (P<0.05); at 12 and 16 weeks after treatment, scores on both the HADS-anxiety subscale and HADS-depression subscale were also significantly lower than baseline in both groups (P<0.05); the observation group was significantly lower than the control group (P<0.05). The overall incidence of adverse events was 12.70% in the observation group, which was significantly lower than 28.33% in the control group (P<0.05). CONCLUSIONS Dupilumab treatment in adults with refractory PN demonstrates superior efficacy compared with thalidomide in improving skin lesions, relieving pruritus, reducing peripheral EOS counts and serum total IgE, and improving quality of life and psychological status, while showing a more favorable safety profile.

Objective To investigate the levels of gross α and gross β activities in different water types within a 40-kilometer radius around the Zhangzhou Nuclear Power Plant prior to its operation. Methods In 2018, drinking water samples were collected from the area surrounding the nuclear power plant during both the wet and dry seasons, including source water, treated water, tap water, and well water. The gross α and gross β activity concentrations were measured using a low-background α/β counter, followed by statistical analysis. Results A total of 80 water samples from different sources around the Zhangzhou Nuclear Power Plant were collected. The average gross α and gross β activity concentrations during the wet season were (0.110 ± 0.036) Bq/L and (0.643 ± 0.028) Bq/L, respectively, while those during the dry season were (0.124 ± 0.032) Bq/L and (0.624 ± 0.026) Bq/L, respectively. There were no significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for the overall sample set (P > 0.05). However, there were statistically significant differences in the gross α and gross β activity concentrations between the wet and dry seasons for source water and well water (Zwet = −2.005, −2.123; Zdry = −1.943, −3.090; P < 0.05). Conclusion The radioactivity levels in different water types within various ranges around the Zhangzhou Nuclear Power Plant before its operation were determined. The measured activity concentrations were at the same level as those from previous investigations in other regions of Fujian Province.

OBJECTIVE:
To explore the safety and effectiveness of the "talus home technique (THT) " in the surgery of pronation open ankle fractures (POAF).
METHODS:
A retrospective analysis was conducted on 14 patients with POAF admitted between January 2023 and December 2023 who met the selection criteria. There were 7 males and 7 females; age ranged from 26 to 58 years, with a median age of 53 years. Injury causes included 9 cases of traffic accident injury, 3 cases of fall from hight injury, and 2 cases of crush injury. There were 5 cases of type Ⅱ, 6 cases of type ⅢA, and 3 cases of type ⅢB according to Gustilo classification; and 6 cases of pronation-abduction grade Ⅲ and 8 cases of pronation-external rotation grade Ⅳ according to Lauge-Hansen classification. Emergency first-stage debridement of the ankle joint was performed, followed by second-stage open reduction and internal fixation surgery. The THT was used through a limited incision on the lateral malleolus to restore the height of the lateral malleolus, rotational alignment, and anatomical relationship of the distal tibiofibular syndesmosis (DTFS). Wound healing was observed postoperatively. At 4 months postoperatively, weight-bearing anteroposterior, lateral, and mortise view X-ray films and CT scans of both ankles were reviewed to measure the medial clear space (MCS), tibiofibular clear space (TFCS), distal fibular tip to lateral process of talus (DFTL), and anterior/posterior syndesmosis distances of DTFS, and the quality of reduction of ankle fractures was evaluated. Ankle joint function was assessed using the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and active dorsiflexion/plantar flexion range of motion were recorded at last follow-up.
RESULTS:
After second-stage internal fixation, 8 patients achieved wound healing by first intention, 1 case had skin edge necrosis, 2 cases had local skin necrosis, 1 case had extensive medial soft tissue defect, and 2 cases developed medial wound infection with sinus formation. All 14 patients were followed up 13-24 months (mean, 16.8 months). Postoperative X-ray films showed 1 case of delayed union of the lateral malleolus, which healed after bone grafting at 12 months; the remaining 13 cases achieved clinical union at 12-32 weeks (mean, 21.5 weeks). At 4 months postoperatively, X-ray films and CT examination showed no significant differences in MCS, TFCS, DFTL, and anterior/posterior syndesmosis distances of DTFS between the healthy and affected sides ( P>0.05), with no poor DTFS reduction. AOFAS ankle-hindfoot score ranged from 80 to 95, with an average of 87.7; ankle range of motion ranged from 10° to 25° (mean, 19.6°) in dorsiflexion and from 32° to 50° (mean, 41.2°) in plantar flexion.
CONCLUSION
THT is safe and effective in POAF surgery. It can restore lateral malleolar height and rotational alignment, enhance DTFS reduction quality, and obtain satisfactory short-term functional recovery of the ankle.

OBJECTIVE:
To evaluate the short-term effectiveness of Ilizarov technique combined with steel needle internal fixation in treating Charcot neuroarthropathy (CN) of the foot and ankle.
METHODS:
Between June 2020 and December 2023, 12 patients with Eichenholtz stage Ⅲ CN of the foot and ankle were treated with Ilizarov technique and steel needle internal fixation. There were 9 males and 3 females with an average age of 48.6 years (range, 19-66 years). The disease duration ranged from 1 to 16 months (mean, 6.8 months). Ankle joint involvement predominated in 7 cases, while midfoot involvement occurred in 5 cases; 3 cases presented with skin ulceration and soft tissue infection. Preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 31.2±9.0, 36-Item Short-Form Health Survey (SF-36)-Physical Component Summary (PCS) score was 32.6±6.8, and Mental Component Summary (MCS) score was 47.8±8.4. Postoperative assessments included wound healing, regular X-ray film/CT evaluations of fusion status, and effectiveness via AOFAS and SF-36-PCS, MCS scores.
RESULTS:
All operations were successfully completed without neurovascular complication. Two patients experienced delayed wound healing requiring intervention, and the others achieved primary healing. All patients were followed up 15-43 months (mean, 23.3 months). Imaging confirmed successful joint fusion within 13-21 weeks (mean, 16.8 weeks). At last follow-up, the AOFAS score was 72.5±6.4, and the SF-36-PCS and MCS scores were 63.2±8.4 and 76.7±5.3, respectively, all of which improved compared to preoperative levels, with significant differences ( P<0.05).
CONCLUSION
Ilizarov technique combined with steel needle internal fixation effectively restores walking function and achieves satisfactory short-term effectiveness in CN of the foot and ankle.

OBJECTIVE:
To evaluate the safety and effectiveness of reducing posterior malleolar fractures via the modified Rammelt transfibular approach.
METHODS:
A retrospective analysis was conducted on 26 patients with ankle fractures who met the selection criteria and were admitted between September 2023 and May 2024. There were 13 males and 13 females, aged from 14 to 59 years (median, 43.5 years). Causes of injury included traffic accident (1 case), falls (7 cases), and sprains (18 cases). Time from injury to operation ranged from 1 to 13 days (mean, 3.9 days). According to the Lauge-Hansen classification, there were 5 supination-external rotation type Ⅲ fractures and 21 supination-external rotation type Ⅳ fractures. According to the Bartoníček classification for posterior malleolar fractures, there were 12 type Ⅱ fractures, 10 type Ⅲ fractures, and 4 type Ⅳ fractures. During operation, the fracture was exposed via the modified Rammelt transfibular approach; then, the fracture reduction was achieved under direct vision using techniques such as towel clip traction, posterolateral compression, and lifting with a posterior transverse periosteal elevator; finally, the fracture was fixed using anteroposterior cannulated screws or Kirschner wires. The incision healing was observed after operation. At 4 months after operation, X-ray film and CT were reviewed to evaluate the quality of fracture reduction. The medial clear space, tibiofibular clear space, and the anterior/posterior tibiofibular syndesmotic distances were measured. At last follow-up, the ankle function was assessed using the American Orthopaedic Foot & Ankle Society (AOFAS) score and the range of motion.
RESULTS:
The marginal necrosis occurred in 2 lateral malleolar incisions, and superficial infection occurred in 1 lateral malleolar incision; the remaining incisions healed by first intention. All 26 patients were followed up 13-21 months (mean, 15.6 months). X-ray films showed that fractures in 25 patients achieved clinical union within 3-8 months (mean, 5.4 months); 1 case had delayed union of the lateral malleolus. At 4 months after operation, no significant difference was found between the injured and healthy sides in the medial clear space, tibiofibular clear space, or the anterior/posterior tibiofibular syndesmotic distances ( P>0.05). No malreduction of the posterior malleolus or the tibiofibular syndesmosis occurred. At last follow-up, the AOFAS score ranged from 80 to 100 (mean, 91.9). The range of motion ranged from 17° to 22° (mean, 21.0°) in active ankle dorsiflexion and from 40° to 49° (mean, 44.6°) in plantar flexion. Internal fixator was removed in 12 patients at 1 year after operation, with no ankle instability occurring. Ankle joint degeneration was observed in 1 patient at last follow-up.
CONCLUSION
The modified Rammelt transfibular approach is a safe and reliable technique. It enables precise reduction under direct vision, improves the quality of reduction for the distal tibial articular surface and the tibiofibular syndesmosis, and provides satisfactory ankle functional recovery in short-term follow-up.
