Objective To analyze the epidemiological characteristics of hepatitis E (HE) in Huai'an City from 2015 to 2024, and construct and validate the prediction effect of the Seasonal Autoregressive Integrated Moving Average (SARIMA) model, and to provide a scientific basis for HE prevention and control. Methods Data of reported HE cases in Huai'an City from January 2015 to December 2024 were extracted from the National Disease Control and Prevention Information System. Descriptive epidemiological methods were used to analyze the temporal, regional and population distribution characteristics of HE incidence. After data preprocessing, stationarity test and randomness test, the SARIMA model was constructed. The optimal model was selected by minimizing the Akaike Information Criterion (AIC). The model performance was evaluated by adjusted R-squared (Adj R²) and root mean square error (RMSE). The monthly incidence rate of HE in Huai'an City in 2025 was predicted and compared with the actual incidence data to validate the model. Results A total of 1 713 HE cases were reported in Huai'an City from 2015 to 2024, showing a fluctuating upward trend. Huaiyin District (339 cases) and Lianshui County (334 cases) were high-incidence areas. The cases were mainly concentrated in people aged 45 and above (83.3%), males (gender ratio 2.37:1) and farmers (70.8%). The optimal model was SARIMA (1,1,1)×(2,0,1)₁₂, with residual as white noise sequence. There was no statistical difference between the actual incidence and predicted value from January to August 2025 (P>0.05). Conclusion HE incidence in Huai'an has obvious aggregation and temporal fluctuation characteristics. The SARIMA model has a good prediction effect, which can provide reference for formulating targeted prevention and control strategies.

Objective To explore the correlation between vitamin D and antiphospholipid antibody(APLa)level in the patients with recurrent spontaneous abortion(RSA).Methods A total of 157 patients with RSA visiting the RSA outpatient department of RSA of Hangzhou Municipal First People's Hospital from January 2022 to April 2023 were selected by the prospective clinical study as the study subjects.Among them,34 RSA cases of vitamin D deficiency complicating APLa abnormality(the study group)conducted the vitamin D supplement intervention and their vitamin D and APLa levels were dynamically monitored;27 RSA patients with vitamin D deficiency and APLa abnormality without vitamin D supplement intervention before intervention or at the same time visiting the department of non-RSA outpatient of this hospital served as the control group.The general data and the relationship between vitamin D and APLa level were compared be-tween the two groups.The pregnant outcomes in the two groups were analyzed.Results There were no differences in the general data such as age and BMI between the two groups(P＞0.05).In the study group,the vitamin D was negatively correlated with the APLa level(P＜0.001);after treatment,the vitamin D level was significantly increased and the APLa level was significantly decreased(P＜0.001).The adverse pregnan-cy outcomes had statistical difference between the two groups(P=0.043).Conclusion Among the patients with RSA,the vitamin D may be negatively correlated with the APLa level.Monitoring and evaluating the vi-tamin D and APLa levels,and adopting the vitamin D intervention before pregnancy as early as possible could prevent the occurrence risk of adverse pregnant outcomes in RSA,thus improve the pregnant outcome.

Objective:To produce 161Tb from enriched 160Gd 2O 3 isotope-enriched target material and realize domestic production of the novel medical isotope 161Tb. Methods:The 160Gd 2O 3 isotope-enriched target material was irradiated with neutrons by the China Mianyang Research Reactor (CMRR). The no-carrier-added 161Tb product was obtained after the processes of target broken, sample dissolution, separation and purification with lanthanide (LN) resin and solution replacement with diglycolamide (DGA) column. Various key indicators such as γ spectral purity, metal impurity content, specific activity, radiochemical purity, and radioactive concentration were used to conduct the quality inspection and the control of 161Tb products. Results:161TbCl 3 of 33.4 GBq was obtained in a single time with the radioactive concentration of 16.8 GBq/ml, nuclear purity more than 99.9%, and radiochemical purity of 99.2%. Metal impurity content was met the established standards, with the specific activity of 6.02×10 17 Bq/mol. The radiochemical purities of 161Tb labeling with 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid- D-Phe1-Tyr3-Thr8-octreotide (DOTATATE) after 0 and 72 h were 100% and 95.8% respectively. Conclusion:The preparation of no-carrier-added 161Tb by using LN resin has the advantages of high separation performance and high sample loading, which has great significance in the field of medical isotope preparation and lays a good nuclide guarantee for the research and development of domestic 161Tb-labeled drugs.

Coronary angiography (CAG) as a typical imaging modality for the diagnosis of coronary diseases hasbeen widely employed in clinical practices. For CAG-based computer-aided diagnosis systems, accurate vessel segmentation plays a fundamental role. However, patients with bradycardia usually have a pacemaker which frequently interferes the vessel segmentation. In this case, the segmentation of vessels will be hard. To mitigate interferences of pacemakers and then extract main vessels more effectively in CAG images, we propose an approach. At first, a pseudo CAG (pCAG) image is generated through a part of a CAG sequence, in which the pacemaker exists. Then, a local feature descriptor is employed to register the relative location of pacemaker between the pCAG image and the target CAG image. Finally, combining the registration result and segmentation results of main vessels and pacemaker, interferences of pacemaker are removed and the segmentation of main vessels is improved. The proposed method is evaluated based on 11 CAG images with pacemakers acquired in clinical practices. An optimization ratio of the Dice coefficient is 12.04%, which demonstrates that our method can remove overlapping pacemakers and achieve the improvement of main vessel segmentation in CAG images.Our method can further become a helpful component in a CAG-based computer-aided diagnosis system, improving its diagnosis accuracy and efficiency.

Background: Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. Methods: Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. Results: Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. Conclusions IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China. Currently, hepatectomy, radiofrequency ablation, interventional therapy, and so on are widely used in the treatment of liver cancer; however the 5-year survival rate of patients is still very poor. The onset of liver cancer is insidious, and most patients do not have the opportunity to undergo surgery when they are initially diagnosed. In addition, patients with advanced liver cancer lack effective treatment, which is mainly due to chronic inflammation of the liver. Immunotherapy has great potential advantages in the treatment of liver cancer, so it has attracted more and more researchers' attention. Importantly, with the development of biomedical science into the era of precision medicine, more precise and effective immunotherapy strategies for HCC treatment have been explored, thus bringing new hope to HCC patients. This article reviews the research status and progress of liver cancer immunotherapy in the context of precision medicine.
