ObjectiveTo assess changes in the incidence， prevalence， and disability-adjusted life-year （DALY） burden of ulcerative colitis （UC） in China and worldwide from 1990 to 2023 using data from the Global Burden of Disease Study 2023 （GBD 2023）， and to examine demographic drivers and future trends. MethodsUC data for China， the world， and 204 countries and territories were extracted from the GBD 2023 Results Tool. Age-standardized incidence rate （ASIR）， age-standardized prevalence rate （ASPR）， and age-standardized DALY rate （ASDR）， with 95% uncertainty interval （UI）， were obtained. Joinpoint regression was used to estimate average annual percent change （AAPC） and 95% confidence interval （CI）. Spearman rank correlation， inequality and frontier analyses， Das Gupta decomposition， and autoregressive integrated moving average （ARIMA） models were used to assess associations with the sociodemographic index （SDI）， cross-country burden disparities， demographic drivers， and trends from 2024 to 2035， respectively. ResultsIn 2023， the ASIR， ASPR， and ASDR in China were 0.94， 5.95， and 5.94 per 100 000 population， respectively， lower than the corresponding global estimates of 2.87， 28.48， and 13.82 per 100 000 population. From 1990 to 2023， China’s ASIR and ASPR increased， with AAPCs of 2.720% （95% CI： 2.133%-3.309%） and 2.261% （95% CI： 1.617%-2.908%）， whereas the ASDR decreased （AAPC=-3.056%， 95% CI： -3.449% to -2.662%）. Globally， ASIR increased slightly， whereas ASPR and ASDR decreased. In China， the crude incidence， prevalence， and DALY rates peaked at ages 50-54 years， 60-64 years， and ≥95 years， respectively. ASIR and ASPR were positively correlated with SDI （r_s=0.5794 and 0.6177， both P<0.001）， whereas the correlation between ASDR and SDI was not statistically significant （r_s=0.0666， P=0.343）. In China， epidemiological change contributed most to increases in incident and prevalent cases， and changes in age-specific rates contributed most to the decline in DALYs； globally， population growth and population aging contributed most to the increase in DALYs. By 2035， China’s ASIR， ASPR， and ASDR were projected to be 1.23， 6.37， and 2.55 per 100 000 population， respectively. ConclusionsFrom 1990 to 2023， the age-standardized incidence and prevalence rates of UC increased in China， whereas the age-standardized DALY rate decreased， and peaks in absolute burden generally shifted toward middle-aged and older age groups. The projected directions may persist. These findings may provide reference for long-term UC management and health-resource planning.

OBJECTIVES: To compare the efficacy of toric implantable collamer lens (Toric-ICL) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for myopia correction in patients with moderate to high myopia complicated with astigmatism. METHODS: We retrospectively collected data from 64 patients (aged 18-42 years) with moderate to high myopia complicated with astigmatism (128 eyes) undergoing either Toric-ICL (28 patients/56 eyes) or FS-LASIK (36 patients/72 eyes) at our department between January, 2019 and December, 2020. The changes of uncorrected distance visual acuity (UCVA), spherical equivalent (SE), mean astigmatism correction index (CI), corneal endothelial cell density (ECD) and intraocular pressure (IOP) following the procedures were compared between the two groups. RESULTS: In FS-LASIK group, all the eyes (72/72) achieved an UCVA≥1.0, similar to the rate in Toric-ICL group (55/56 eyes; P=0.2374). The postoperative SE was also comparable between FS-LASIK and Toric-ICL groups [0.43±0.06 D (range: -1.0 to 1.50 D) vs 0.38±0.05 D (range: -0.75 to 1.00 D); P=0.56]. The mean astigmatism CI was significantly higher in FS-LASIK group than in Toric-ICL group (0.8561 vs 0.7176; P<0.0001), and 88.89% of the eyes in FS-LASIK group and 69.64% in Toric-ICL group had postoperative astigmatism ≤0.50 D. No significant changes were observed in postoperative corneal ECD in FS-LASIK group, whereas ECD decreased significantly after the procedure in Toric-ICL group (P=0.0057). The patients undergoing Toric-ICL exhibited no significant changes of postoperative IOP, but the patients receiving FS-LASIK had significantly reduced IOP after the procedure (P<0.001). CONCLUSIONS Although the patients included in Toric-ICL group had higher myopia and astigmatism, Toric-ICL still showed better predictability and efficacy for astigmatic correction in Toric-ICL group. Toric-ICL is an effective and safe equivalent of FS-LASIK for correcting moderate myopia but can be more advantageous for correcting high myopia with astigmatism.

Objective:To develop an intelligent recognition and precise segmentation technique using ultrasonic images，and to enhance diagnostic efficiency and accuracy.Methods:A total of 1，430 patients diagnosed with uterine fibroids through transvaginal ultrasonography at the Maternal and Child Health Hospital of Guangming from November 2020 to October 2024 were retrospectively included. Ultrasonic images were manually annotated by two experienced physicians and reviewed by a senior expert. The Mask DINO deep learning model was used for lesion segmentation，and the segmentation results were optimized using ellipse fitting technology. Model performance was evaluated using the Dice coefficient，intraclass correlation coefficient（ICC），mean absolute error（MAE），and measurement accuracy.Results:In the test set of 286 cases，the average Dice coefficient of model prediction was 0.992，indicating extremely high segmentation accuracy. The average accuracy of lesion identification by the model was 0.909，with 241 correctly identified samples，19 basically correct samples，and 26 incorrect samples. In terms of long and short axis measurements，the ICC of the model's direct predictions were 0.871（short axis）and 0.784（long axis），with MAE of 0.436 cm（short axis）and 0.508 cm（long axis）. After optimization with ellipse fitting，the ICC increased to 0.893（short axis）and 0.866（long axis），and the MAE decreased to 0.191 cm（short axis）and 0.274 cm（long axis），the measurement accuracy improved significantly.Conclusions:The intelligent recognition and precise segmentation technique for uterine fibroids based on ultrasonic images constructed in this study performed excellently in lesion segmentation and measurement，it can significantly improve the efficiency and accuracy of diagnosis.

Objective To analyze and evaluate the implementation effect of tuberculosis prevention and control program in Wuhan, and to provide reference for scientific formulation of tuberculosis prevention and control measures. Methods Using the National Tuberculosis Information Management System, descriptive statistical analysis was carried out on the medical record information of pulmonary tuberculosis patients registered in Wuhan , 2016 - 2021. Results A total of 34 937 cases of pulmonary tuberculosis were registered in Wuhan , with an average annual incidence rate of 49.85/100 000. The incidence rate showed a downward trend year by year, with a statistically significant difference in 2016—2021 (χ²_trend = 708.387, P<0.001). The patients mainly came from referrals, accounting for 71.86%, and the proportion of referrals varied significantly among different years (χ²=355.541, P<0.001). The diagnosis type was mainly pathogenic negative, accounting for 49.12%. The proportion of pathogenic negative had statistically significant difference among different years (χ²=1 354.830, P<0.001). The proportion of patients cured and completed the course of treatment reached 93.98%, with statistically significant differences in the proportions among different years (cured, χ²=1 080.252, P<0.001; completed the treatment course, χ²= 933.655, P<0.001). The sputum examination rate of newly diagnosed patients in each year reached over 90%, and the overall completion rate reached over 95%. The proportion of positive pathogens showed an increasing trend year by year. Conclusion The overall epidemic situation of tuberculosis in Wuhan is declining year by year, and tuberculosis prevention and control work has achieved remarkable results. Active screening in key areas and populations should be strengthened, and prevention and control strategies should be formulated by emphasizing the key and difficult points.

Objective:To conduct scoping review of researches on application of traditional Chinese medicine exercises in exercise rehabilitation of patients with heart failure, so as to provide reference for effective clinical intervention of traditional Chinese medicine exercises.Methods:Chinese and English literature published in PubMed, Web of Science, Cochrane Library, Embase, CNKI, VIP, Wanfang Database and China Biology Medicine disc were searched by computer, and the search deadline was from database establishment to May 28, 2023. The Joanna Briggs Institute Scoping Review Guide was used as a methodological framework to summarize and analyze the included literature.Results:A total of 19 literatures were included, including 17 randomized controlled trials and 2 quasi-randomized controlled trials. The subjects of the intervention were heart failure patients with New York Heart Association heart function gradeⅠ toⅢ. The types of exercises mainly included Eight Pieces of Brocade and Tai Chi. The intervention duration was mostly 30 min each time, and the frequency was mostly 3 to 5 times a week. The intervention intensity was mostly based on The Borg Rating of Perceived Exertion (RPE), and the intervention duration was mostly 3 months. Most of the implementation scenarios were "hospital-home" or home. Traditional Chinese medicine exercises had a positive effect on the clinical symptoms, psychological state and quality of life of patients with heart failure, and were safe and feasible.Conclusions:Traditional Chinese medicine exercises have a positive effect on the exercise rehabilitation of patients with heart failure, and are safe and feasible.

Qi and blood are the two cornerstones of the theoretical system of traditional Chinese medicine.Luobing theory con-structs an academic system with the prominent characteristics of"Qi-blood correlation"to guide the prevention and treatment of compli-cated diseases of internal injury and severe external diseases.Qi is the leader of blood,blood is the mother of Qi,qiluo runs meridian qi,mailuo runs blood,and the relationship between qiluo and mailuo is essentially a dialectical relationship between Qi and blood.Qi and blood play a role in the regulation of collaterals,warming and nourishing,blood supply and Qi supply,and the exchange of Jin and blood.The normal structure and function of collateral vessel is the key factor to maintain the normal structure and function of the viscer-a.The collateral vessel entering the viscera is the collateral of the viscera,and entering the heart is divided into the mailuo of the heart and the qiluo of the heart.Cardiac mailuo infiltration can nourish the heart tissue and provide material basis for maintaining the struc-ture and function of the heart,which is identical with the modern medical coronary system and cardiac microvessels;qiluo regulates cardiac function,maintains cardiac systolic pulsation,and has the same identity with cardiac conduction system and regulatory mecha-nism.The interaction of mailuo disease and qiluo disease can lead to arrhythmias,such as coronary heart disease arrhythmias and pri-mary arrhythmias.According to the therapeutic principle that collateral vessels work by circulation,the key to the treatment of arrhyth-mia is to unobstruct the collateral veins and harmonize Qi and blood,which has important guiding value for the treatment of arrhythmia.The treatment of arrhythmias should not only remove pathogenic factors and improve cardiac conduction function,but also protect cardiac microcirculation,especially for arrhythmias without clear organic disease,which provides a new idea for the prevention and treatment of arrhythmias by combining traditional Chinese and Western medicine.

Objective:To explore the clinical application value of multiple cytogenetic and molecular genetic techniques in the diagnosing of chromosomal microstructural abnormalities.Methods:The proband was a 30-year-old man. He went to Reproductive Medicine Center of Shenzhen Zhongshan Urology Hospital in July 2021 because of a 7-year history of primary infertility. Chromosome karyotype was analyzed by conventional G-banding technique. One case was found to be suspected of microstructural aberration in X chromosome. The origin and structural characteristics of this X chromosome structural aberration was identified by high-resolution G-banding, copy number variation sequencing (CNV-seq), C-banding and fluorescence in situ hybridization (FISH). The pregnancy outcome of this case was followed up. Results:Conventional G-banding karyotype of peripheral blood lymphocytes was initially diagnosed as 46, Y, ?inv(X)(p22.3p22.2). The final karyotype of proband was interpreted as 46, Y, der(X) t(X; Y)(p22.3; q12) mat by high-resolution G-banding karyotype analysis, CNV-seq, C-banding analysis and FISH detection. His spouse had conceived singleton pregnancy via in vitro fertilization and embryo transfer. Prenatal diagnosis had been performed. Karyotype of amniotic fluid was 46, X, der(X) t(X; Y)(p22.3; q12) pat. No structural malformation was detected prenatally by ultrasound. The neonate was phenotypically normal one month after birth. Conclusion:The combined application of multiple cytogenetic and molecular genetic techniques can provide a reliable technical platform for characterizing the microscopic structural aberrations of chromosomes, and an important genetic basis for exploring the phenotype, prognosis and offspring risk of such patients.
