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.

Objective To explore the value of combined ultrasound parameters, including the hepatorenal index (HRI) and renal resistance index (RRI), with cystatin C (CysC) in monitoring early acute kidney injury (AKI) after liver transplantation. Methods Perioperative data from 121 liver transplant recipients who received organs from donation after brain death were collected. The HRI and RRI of the recipients were measured on postoperative days 1-7 and at 1 month, and the CysC levels were measured on postoperative day 1. The recipients were divided into the AKI group (n=53) and the non-AKI group (n=68) based on whether AKI occurred within 7 days after operation. The data of the two groups were compared, and the ultrasound parameters before and after recovery in the AKI group were analyzed. The value of combined HRI, RRI and CysC in monitoring AKI was also analyzed. Results AKI occurred in 53 recipients, with an incidence rate of 43.8%, including 30 cases of stage 1, 18 cases of stage 2, and 5 cases of stage 3. Among them, 49 cases occurred on postoperative day 1, and 4 cases occurred on postoperative day 2. Of these, 43 cases recovered within 7 days after surgery, 8 cases recovered within 2 months after surgery, 1 case was lost to follow-up, and 1 case received renal replacement therapy. The body mass index and preoperative CysC levels were higher in the AKI group than in the non-AKI group, and the operative time was longer in the AKI group than in the non-AKI group (all P < 0.05). The HRI on postoperative day 1 was lower in the AKI group than in the non-AKI group, while the RRI and CysC levels were higher (all P < 0.05). When AKI occurred, the HRI was lower than the baseline level, and the RRI was higher than the baseline level. As AKI recovered, the HRI gradually increased, and the RRI gradually decreased. The receiver operating characteristic curve analysis showed that the sensitivity and specificity of HRI ≤ 1.12 for predicting AKI were 0.623 and 0.878, respectively, with an area under the curve (AUC) of 0.801. The sensitivity and specificity of RRI ≥ 0.65 for predicting AKI were 0.878 and 0.676, respectively, with an AUC of 0.825. The sensitivity and specificity of CysC ≥ 1.38 mg/L for predicting AKI were 0.736 and 0.882, respectively, with an AUC of 0.851 (all P<0.01). The combination of HRI and CysC (AUC=0.897, P<0.01), RRI and CysC (AUC=0.910, P<0.01), and all three parameters combined (AUC=0.934, P<0.01) were more effective than using each parameter alone. Conclusions HRI and RRI may be used to monitor the occurrence and recovery of early AKI after liver transplantation. The combination of these two parameters with CysC has a high application value in monitoring early AKI after liver transplantation.

ObjectiveTo investigate the immunological characteristics of the patients with aplastic anemia (AA) and elevated hemogram parameters treated with Yiqi Yangxue prescription combined with Western medicine and the predictive effects of immunological indexes on elevated hemogram parameters, thus providing a reference for the prediction of the treatment efficacy and the adjustment of the treatment regimen. MethodA retrospective study was conducted, involving 77 AA patients treated with Yiqi Yangxue prescription combined with Western medicine for 6 months in 19 medical institutions including Xiyuan Hospital, China Academy of Chinese Medical Sciences from September 2018 to March 2021. The patients were assigned into two groups according to the elevations in hemogram parameters [including hemoglobin (HGB), white blood cell count (WBC), platelet (PLT), and absolute neutrophil count (ANC)] after 6 months of treatment. One group had the elevation <50%, and the other group had the elevation ≥50% compared with the baseline. The clinical and immunological characteristics were compared between the two groups. Result① Compared with the group with HGB elevation<50%, the group with HGB elevation≥50% showed elevated level of CD3+ human leukocyte antigen-DR (HLA-DR)+ and increased proportion of patients with T-helper cell type 2 (Th2)<5%, CD8+≥50%, and CD3+HLA-DR+≥9% before treatment (P<0.05, P<0.01). The multivariate Logistic regression analysis showed that CD8+≥50% before treatment was the independent influencing factor for HGB elevation ≥50% [odds ratio (OR)=12.000, 95% confidence interval (CI) 2.218, 64.928, P<0.01]. ② Compared with the group with WBC elevation<50%, the group with WBC elevation≥50% showed increased proportion of patients with CD3+HLA-DR+<6% and T-box transcription factor (T-bet)≥200% before treatment (P<0.05). The multivariate Logistic regression analysis showed that CD3+HLA-DR+<6% (OR=2.998, 95%CI 1.036, 8.680, P<0.05) and T-bet≥200% (OR=3.634, 95%CI 1.076, 12.273, P<0.05) before treatment were independent influencing factors for WBC elevation≥50%. ③ Compared with the group with PLT elevation<50%, the group with PLT elevation≥50% presented lowered Th1 and CD3+HLA-DR+ levels and increased proportion of patients with Th1<12%, CD4+≥6%, and CD3+HLA-DR+<5% before treatment (P<0.05, P<0.01). The multivariate Logistic regression analysis showed that CD3+HLA-DR+<5% before treatment was the independent influencing factor for PLT elevation≥50% (OR=16.190, 95%CI of 3.430 to 76.434, P<0.01). ④ Compared with the group with ANC elevation<50%, the group with ANC elevation≥50% showed no significant changes in the hemogram parameters before treatment. ConclusionAs for the AA patients with rapid elevation in HGB, Yiqi Yangxue prescription combined with Western medicine demonstrate significant effects in the patients with Th2<5% and CD3+HLA-DR+≥9%, especially those with CD8+≥50%. As for the AA patients with rapid elevation in WBC, the therapy was particularly effective in the patients with CD3+HLA-DR+<6% and T-bet≥200%. As for the AA patients with rapid growth in PLT, the therapy was particularly effective in the patients with Th1<12% and CD4+≥6%, especially those with CD3+HLA-DR+<5%.

Objective:Exploring the value of contrast enhanced ultrasound (CEUS) plus transient elastography in evaluating donor livers for C-I donors and predicting the occurrence of early allograft dysfunction (EAD).Methods:Between September 1, 2022 and August 31, 2023, the relevant clinical data were retrospectively reviewed for 75 pairs of donors and recipients. Based upon whether or not there was a postoperative onset of EAD, the recipients were assigned into two groups of EAD (16 cases) and non-EAD (59 cases) . All donors were examined by contrast-enhanced ultrasonography and FibroScan. QLAB analysis software was utilized for analyzing the results of contrast-enhanced ultrasound. Liver parenchyma at 3 cm below liver capsule was selected as a region of interest for plotting the time-intensity curve (TIC) . And the contrast-enhanced ultrasonic parameters of two groups were recorded. FibroScan transient elastography instrument was employed for quantifying liver stiffness 12 times in right lobe of donor liver and recording quantitative parameters of liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) .Results:Inter-group comparison of gender, age, body mass index (BMI) and ICU length of stay showed no statistically significant differences ( P>0. 05) . However, significant differences existed in the levels of platelet [ (122. 44±85. 82) vs (197. 22± 140. 93) ×10 9/L]and cholinesterase [ (3 473. 44±1 368. 54) vs (4 252. 93±1 365. 37) U/L]within the first 24h pre-operation ( P=0. 047, P=0. 047) . Peak intensity (PKI) and area under the curve (AUC) were lower in EAD group than those in non-EAD group [ (16. 44±4. 70) dB vs 19. 85±4. 39 dB, P=0. 009; (1 366. 76±508. 10) dB·s vs (1 675. 23±498. 77) dB·s, P=0. 014]. There were statistically significant differences ( P=0. 009, P=0. 032) . Arterial-portal arrival interval (APAI) and LSM were higher in EAD group than those in non-EAD group[6. 50 (5. 00, 10.75) s vs 5. 00 (4. 00, 7. 00) s, P =0. 24; 8. 60 (6. 32, 11. 65) kPa vs 6. 10 (5. 40, 7. 90) kPa, P=0. 014]. Receiver operating characteristic (ROC) curve analysis revealed that PKI, AUC, APAI and LSM had AUC values of 0. 703, 0. 664, 0. 683 and 0. 702, respectively in predicting postoperative EAD. And combined prediction of EAD occurrence based upon these parameters had an AUC of 0. 776, a Youden index of 0. 508 with cutoff values, sensitivity and specificity of 0. 800, 0. 813 and 0. 695 respectively. Spearman' s correlation analysis revealed a negative correlation between APAI and AUC values ( r= -0. 404, P<0. 001) . Conclusions:The combination of CEUS and transient elastography can comprehensively evaluate the status of microcirculatory perfusion, fibrosis and steatosis of liver grafts from brain death donors. It offers a great predictive value for postoperative occurrence of EAD.

OBJECTIVE To provide reference for the rational use of antiemetic drugs in tumor chemotherapy patients. METHODS The data of tumor patients who were given antiemetic drugs were collected from 9 departments of our hospital with hospital information system from Oct. 1st to Nov. 30th in 2022, such as oncology department, radiotherapy department, gynecology department, and gastroenterology department. The application of chemotherapy drugs and the use of antiemetic drugs were analyzed statistically, and the irrational use of antiemetic drugs was analyzed. RESULTS A total of 520 patients were included, involving 248 (47.69%) using chemotherapy drugs with a moderate emetogenic risk level and 135 (25.96%) with a high emetogenic risk level. A total of 461 cases (73.06%) of 5-hydroxytryptamine 3-receptor antagonists were used, including palonosetron in 333 cases, ondansetron in 106 cases, tropisetron in 15 cases and granisetron in 7 cases, and only 148 cases of patients were prioritized for the use of nationally procured medicines and national essential medicines (32.10%). Neurokinin-1 receptor antagonists were used in 170 cases (26.94%), including fosaprepitant in 112 cases and aprepitant in 58 cases. The use of antiemetic drugs was unreasonable in 162 patients (31.15%); among the types of irrational drugs, the antiemetic regimen was unreasonable in the largest number of cases (22.40%), followed by the irrational pharmacoeconomics (19.13%). CONCLUSIONS The emetogenic risk levels of chemotherapy drugs used for tumor patients in our hospital are primarily moderate to high, and there is irrational use of antiemetic regimen and pharmacoeconomics. Clinicians, nurses, pharmacists and hospital departments should collaborate as multiple teams to strengthen full supervision of the standardization of antiemetic drugs, reasonably select antiemetic drugs based on emetogenicity rating, and improve the compliance of doctors with the guidelines to ensure the safety, effectiveness, and cost-effective of patient medication.

Various types of industrial parks in Shanghai play an important role in promoting industrial upgrading and technological progress, yet they are also fraught with occupational health hazards. To effectively promote workplace health and enable various industrial parks to play a positive role, the Shanghai Municipal Government has proposed accelerating the construction of healthy industrial parks. To meet the requirements for the scientific and standardized construction of healthy parks, the Shanghai Municipal Center for Disease Control and Prevention has compiled the Guidelines for Healthy Industrial Park Construction(Guidelines). Adhering to the overall principles of scientific, feasibility, advancement, and standardization, the Guidelines address three construction levels: industrial parks, employers, and employees. They set clear requirements for organizational management, healthy environments, health services, health activities, and occupational health in the workplaces, respectively. The Shanghai healthy industrial park evaluation form was provided as an informative appendix for the Guidelines. The Guidelines offer a scientific basis for standardizing and guiding the construction of healthy industrial parks, providing new solutions and technical support for urban occupational health management.
