Objective To investigate the effect of contrast-enhanced ultrasonography (CEUS) on the treatment of knee synovial lesions in rheumatoid arthritis (RA).Methods The results of routine ultrasonography (US) and CEUS were observed in 37 patients with RA.Among them 26 knees were underwent review after treatment.The results before and after treatment were compared.Results Routine US showed that the synovial thickness of patella,medial and lateral condylar and the depth of suprapatellar bursa effusion in 37 knee joints were (0.47 ± 0.26)cm,(0.31 ± 0.15)cm,(0.36 ± 0.21)cm and (0.72 ± 0.42)cm before treatment,and (0.36± 0.16)cm,(0.28 ± 0.17)cm,(0.30 ± 0.19)cm and (0.41 ± 0.19)cm in 26 knee joints after treatment,respectively,the differences were statistically significant(P <0.05).The synovial blood flow classification of patella,medial and the lateral condyle in the 26 knee joints had difference between before and after treatment (P <0.05).CEUS showed that the peak intensity decreased,the area under the curve reduced,the time from peak to one half decreased,the wash in slope decreased and the time to peak prolonged in synovial after treatment,the differences of the parameters between before and after treatment were statistically significant(P <0.05).The area of synovial had some influence on the CEUS parameters and could improve the reliability of the evaluation to CEUS for treatment.Conclusions CEUS is an objective method to evaluate the efficacy of RA,which provides a reliable basis for clinical treatment of RA.

AIM: To investigate the alterations in corneal aberration and relative refractive power following the reduction of back optic zone diameters(BOZD)of orthokeratology lenses.METHODS: Myopic children aged 8-12 years, deemed suitable and willing to wear orthokeratology lenses, were randomly allocated to wear lenses with a 6.0 mm BOZD or a 5.0 mm BOZD. Data collection included changes in higher-order aberrations, relative refractive power and the treatment zone diameter of the two groups after wearing lenses for 1 d, 1 wk, 1, and 3 mo. The correlation of increase in corneal higher-order aberrations with refractive power was analyzed.RESULTS: The increases in total higher-order aberrations, spherical aberrations and coma aberrations varied over time following lens wear(all P<0.001), and there were no statistically significant differences in the changes of total higher-order aberrations and coma aberrations between the two groups of patients(all P>0.05). A significant difference was observed in the increment of spherical aberrations in the 5 mm range between the two groups of patients, which varied over time(Ftime=40.179, Ptime<0.001; Fgroup=11.948, Pgroup=0.001; Finteraction=3.262, Pinteraction=0.03). A significant difference was observed in the increment of spherical aberrations in the 4 mm range between the two patient groups(Ftime=34.462, Ptime<0.001; Fgroup=13.094, Pgroup<0.001; Finteraction=1.372, Pinteraction=0.25). There was no statistically significant distinction in relative refractive power between the two groups(Fgroup=0.048, Pgroup=0.83; Finteraction=1.208, Pinteraction=0.31); however, relative refractive power changed over time(Ftime=40.030, Ptime<0.001). The difference in treatment zone diameter between the two groups was statistically significant, with changes over time(Ftime=11.212, Ptime<0.001; Fgroup=74.073, Pgroup<0.001; Finteraction=0.312, Pinteraction=0.82). The total higher-order aberrations, spherical aberrations, and coma aberrations in 4, 5 and 6 mm range showed a positive correlation with relative refractive power values(all P<0.001). Statistically significant difference was observed in the axial length between the two groups after wearing lenses for 3, 6 and 12 mo(Ftime=185.398, Ptime<0.001; Fgroup=5.618, Pgroup=0.02; Finteraction=2.315, Pinteraction=0.11).CONCLUSION: Orthokeratology lenses leaded to elevated higher-order aberrations. Orthokeratology lenses with smaller BOZD produced significantly greater spherical aberrations at 4 and 5 mm range and smaller treatment zone diameters. The corneal total higher-order aberration was positively correlated with relative refractive power. Wearing orthokeratology lenses with a smaller BOZD can cause slower axial growth and better myopia control.

Determining effective traditional Chinese medicine (TCM) treatments for specific disease conditions or particular patient groups is a difficult issue that necessitates investigation because of the complicated personalized manifestations in real-world patients and the individualized combination therapies prescribed in clinical settings. In this study, a multistage analysis method that integrates propensity case matching, complex network analysis, and herb set enrichment analysis was proposed to identify effective herb prescriptions for particular diseases (e.g., insomnia). First, propensity case matching was applied to match clinical cases. Then, core network extraction and herb set enrichment were combined to detect core effective herb prescriptions. Effectiveness-based mutual information was used to detect strong herb-symptom relationships. This method was applied on a TCM clinical data set with 955 patients collected from well-designed observational studies. Results revealed that groups of herb prescriptions with higher effectiveness rates (76.9% vs. 42.8% for matched samples; 94.2% vs. 84.9% for all samples) compared with the original prescriptions were found. Particular patient groups with symptom manifestations were also identified to help investigate the indications of the effective herb prescriptions.

Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer death worldwide. It is urgent to develop new drugs to improve the prognosis of ESCC patients. Here, we found benzydamine, a locally acting non-steroidal anti-inflammatory drug, had potent cytotoxic effect on ESCC cells. Benzydamine could suppress ESCC proliferation in vivo and in vitro. In terms of mechanism, CDK2 was identified as a target of benzydamine by molecular docking, pull-down assay and in vitro kinase assay. Specifically, benzydamine inhibited the growth of ESCC cells by inhibiting CDK2 activity and affecting downstream phosphorylation of MCM2, c-Myc and Rb, resulting in cell cycle arrest. Our study illustrates that benzydamine inhibits the growth of ESCC cells by downregulating the CDK2 pathway.
