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.

Objective To investigate the clinical value of 99Tcm-methoxyisobutylisonitrile (MIBI) double-phase imaging in differential diagnosis of bone lesions in tumor patients,which was indefinite in 99Tcm-methylene diphosphonate (MDP) bone imaging,and evaluate the correlation between 99Tcm-MIBI imaging and chemotherapy efficacy.Methods Fifty-two tumor patients (23 males,29 females,mean age 58 years) with bone isolated lesions(≤3) found by 99Tcm-MDP bone scintigraphy was enrolled from June 2014 to November 2015.Since the results of 99Tcm-MDP imaging were indefinite,99Tcm-MIBI double-phase (10 min and 30 min after injection of 99Tcm-MIBI) SPECT/CT imaging was then performed within 1 week.The final diagnosis was made according to results of more than two imaging modalities (CT,MRI,PET/CT) and/or follow-up (≥6 months).The diagnostic efficacy of 99Tcm-MIBI SPECT/CT imaging was calculated.The clinical dataof chemotherapy were also collected.Patients with bone metastasis were grouped as the treatment response.Retention index (RI) of metastatic lesions was calculated and compared between different groups using two-sample t test.The relationship between RI and chemotherapy efficacy was investigated by Spearman correlation analysis.Results A total of 12 benign lesions and 84 malignant lesions were eventually diagnosed.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV) and Youden index of 99Tcm-MIBI imaging were 96.43％(81/84),83.33％(10/12),97.59％(81/83),76.92％(10/13),and 0.80,respectively.The RI was statistically different between complete remission (CR)+partial remission (PR) group and stable disease (SD) + progressive disease (PD) group:-0.142± 0.036 vs-0.384± 0.067 (t =2.367,P＜0.05).The RI of 99Tcm-MIBI in bone metastases was positively correlated with the chemotherapy efficacy (rs =0.78,P＜0.01).Conclusions 99Tcm-MIBI imaging is helpful in differential diagnosis of bone lesions with indefinite diagnosis by 99Tcm-MDP bone imaging in tumor patients.99Tcm-MIBI RI of bone metastasis may predict the therapeutic response of chemotherapy efficacy.

This study was aimed to work out a simple, applicable, sensitive and specific protocol for the identification of phosphoproteome. Isotope-labeling, two-dimensional electrophoresis, autoradiography and so on were used to establish a phosphoproteome map of mice neurons, and then chemiluminescence Western blotting was utilized to detect three phosphoproteins PI3Kr3, MEK1 and PKCalpha selectively. The results of comparison showed that the blots of PI3Kr3, MEK1 and PKCalpha on autoradiography map were almost identical with the blots of PI3Kr3, MEK1 and PKCalpha on chemiluminescence Western blotting maps. So this protocol based on isotope labeling and chemiluminescence Western blotting methods has proven to be sensitive and specific in the identification of phosphoproteome.
