Objective To analyze the trend of global cellulitis disease burden from 1990 to 2019, and to provide a theoretical basis for the prevention and control of cellulitis disease. Methods The Global Burden of Disease 2021 (GBD2021) data were collected, and data on the incidence, mortality, and disability-adjusted life year (DALY) of cellulitis were analyzed for each country worldwide. The estimated annual percentage change (EAPC) and age-standardized rate (ASR) were used to estimate the trend change of cellulitis from 1990 to 2021. Results The global burden of cellulitis increased significantly in 2021, with 55.96 million cases, 28.9 million deaths and 876.1 million DALYs, respectively. Incidence and mortality rates were generally higher in males than in females. The incidence and DALYs were higher in high SDI regions, with the highest burden observed in South Asia. In contrast, East Asia exhibited the lowest burden and demonstrated a declining trend. There were significant differences between countries, with India having the highest prevalence, the United States having the highest incidence, and Bahrain having the fastest growing rate.In 2021, China had the lowest age-standardised incidence of cellulitis in the world and the fastest declining age-standardised incidence and age-standardised DALYs. Conclusion The global disease burden of cellulitis is increasing from 1990-2021, and cellulitis remains an an important global public health problem. Targeted preventive meausres should be taken in areas with different economical levels. Men, middle-aged and elderly people, and newborns are the key groups in need of attention and health education.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

OBJECTIVE To evaluate the effectiveness, safety, economy, innovation, suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein (EC), and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin (TB-PPD) were analyzed by the method of systematic review. Cost minimization analysis, cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD, and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation, suitability and accessibility were determined by systematic review and improved Delphi expert consultation, and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness, safety, economy, innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent, while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight, the scores of effectiveness, safety, economy, innovation, suitability, accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD, EC performs better in all dimensions of effectiveness, safety, economy, innovation, suitability and accessibility. However, it is worth noting that EC should further improve its availability in the dimension of accessibility.

OBJECTIVE:
This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province.
METHODS:
We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed.
RESULTS:
The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α 3.7/αα (50.23%) and β IVS-II-654/β N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively.
CONCLUSION
Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

ObjectiveTo explore the association between telomere length of leukocytes and chronic heart failure (CHF). MethodsA total of 224 patients were recruited in this study. The patients were divided into non-CHF (Non-CHF) group (involving 117 patients) and CHF group (involving 107 patients) according to left ventricular ejection fraction. Telomere length of peripheral blood leukocytes was measured by real-time fluorescence quantitative polynucleotide chain reaction (qPCR). Telomere length of leukocytes was compared between Non-CHF group and CHF group. Binary Logistic regression model was used to analyze the association between telomere length and CHF. ResultsTelomere length in Non-CHF patients and CHF patients was 0.9(0.64~1.18), 0.7(0.53~0.89), respectively. Telomere length was shorter in CHF patients than in Non-CHF patients (P<0.001). Further results showed that telomere length was associated with CHF [OR=0.17, 95% CI was (0.07, 0.40), P<0.05]. After adjusting confounding factors, telomere length was still associated with CHF [OR=0.14, 95% CI was ( 0.05, 0.33), P<0.05]. ConclusionThe results show that telomere length of peripheral blood leukocytes is independently associated with CHF.

Objective To explore the eff cacy and safety of 6-month and 12-month dual antiplatelet therapy(DAPT)after implantation of biodegradable polymer-drug eluting stents(BP-DES) in elderly patients. Methods This study was a subgroup analysis of the I-LOVE-IT 2 trial, which was a prospectively randomized study enrolling 2737 patients receiving either a BP-SES or a DP-SES in a 2:1 ratio. This studied further divided the patients who were randomized to the BP-SES group,whose age ≥ 65 year old, in a 1:1 ratio to receive a 6-month DAPT (n=319) or 12-month DAPT (n=308)randomly before the index PCI. The primary end point of this study was 12-month target lesion failure (FhF, including cardiac death,target vessel myocardial infarction and clinically indicated target lesion revascularization)and the secondary end points was 12-month net adverse clinical and cerebral events (including all-cause death, all myocardial infarction, stroke and all bleeding). Results Rates of TLF at 12 months were 7.1% in the 6-month DAPT group and 7.2% in the 12-month DAPT group (P=0.980). No diff erences were observed in the occurrence of events in the secondary endpoint at 12 months follow-up between the 6-month DAPT group and 12-months DAPT group(14.1% versus 13.0%, P=0.726). There were no signifi cant diff erences in stent thrombosis or bleeding complications between the 2 groups. Conclusions This study shorted that 6-month DAPT did not increase the risk of TLF at 12 months after implantation of DES in elderly patients compared with 12-month DAPT. Elderly patients are at high risk of bleeding and ischemic events and study show that 6-month DAPT would be adequate. These results need to be confi rmed with trials of scale in the future.
