RESUMEN

Objectives: Ultrasound (US) imaging is a relatively novel strategy to monitor the activity of the blood-brain barrier, which can facilitate the diagnosis and treatment of neurovascular-related metastatic tumors. The purpose of this study was to investigate the clinical significance of applying a combination of US imaging outcomes and the associated genes. This was performed to construct line drawings to facilitate the prediction of brain metastases arising from breast cancer. Methods: The RNA transcript data from The Cancer Genome Atlas (TCGA) database was obtained for breast cancer, and the differentially expressed genes (DEGs) associated with tumor and brain tumor metastases were identified. Subsequently, key genes associated with survival prognosis were subsequently identified from the DEGs. Results: Tripartite motif-containing protein 67 (TRIM67) was identified and the differential; in addition, the survival analyses of the TCGA database revealed that it was associated with brain tumor metastases and overall survival prognosis. Applying independent clinical cohort data, US-related features (microcalcification and lymph node metastasis) were associated with breast cancer tumor metastasis. Furthermore, ultrasonographic findings of microcalcifications showed correlations with TRIM67 expression. The study results revealed that six variables [stage, TRIM67, tumor size, regional lymph node staging (N), age, and HER2 status] were suitable predictors of tumor metastasis by applying support vector machine-recursive feature elimination. Among these, US-predicted tumor size correlated with tumor size classification, whereas US-predicted lymph node metastasis correlated with tumor N classification. The TRIM67 upregulation was accompanied by upregulation of the integrated breast cancer pathway; however, it leads to the downregulation of the miRNA targets in ECM and membrane receptors and the miRNAs involved in DNA damage response pathways. Conclusions: The TRIM67 is a risk factor associated with brain metastases from breast cancer and it is considered a prognostic survival factor. The nomogram constructed from six variables-stage, TRIM67, tumor size, N, age, HER2 status-is an appropriate predictor to estimate the occurrence of breast cancer metastasis.

RESUMEN

BACKGROUND: To explore the value of quantitative shear wave elastography (SWE) plus the Breast Imaging Reporting and Data System (BI-RADS) in the identification of solid breast masses. METHODS: A total of 108 patients with 120 solid breast masses admitted to our hospital from January 2019 to January 2020 were enrolled in this study. The pathological examination served as the gold standard for definitive diagnosis. Both SWE and BI-RADS grading were performed. RESULTS: Out of the 120 solid breast masses in 108 patients, 75 benign and 45 malignant masses were pathologically confirmed. The size, shape, margin, internal echo, microcalcification, lateral acoustic shadow, and posterior acoustic enhancement of benign and malignant masses were significantly different (all P < 0.05). The E mean, E max, SD, and E ratio of benign and malignant masses were significantly different (all P < 0.05). The E min was similar between benign and malignant masses (P > 0.05). The percentage of Adler grade II-III of the benign masses was lower than that of the malignant masses (P < 0.05). BI-RADS plus SWE yielded higher diagnostic specificity and positive predictive value than either BI-RADS or SWE; BI-RADS plus SWE yielded the highest diagnostic accuracy among the three methods (all P < 0.05). CONCLUSION: SWE plus routine ultrasonography BI-RADS has a higher value in differentiating benign from malignant breast masses than color doppler or SWE alone, which should be further promoted in clinical practice.

RESUMEN

BACKGROUND: To explore the clinical application value of contrast-enhanced ultrasound (CEUS) in the pathological grading and prognosis prediction of hepatocellular carcinoma (HCC). METHODS: A retrospective analysis was performed of 128 patients with primary HCC who underwent CEUS examination in our hospital from January 2017 to June 2020. Patients were divided into three groups: highly-differentiated group, moderately-differentiated group, and poorly-differentiated group. Quantitative analysis of the relationships between the rise time (RT), time to peak (TTP), mean transit time (mTT), intensity maximum (Imax), enhancement rate, and pathological grade of CEUS was performed. In addition, the follow-up patients were divided into a recurrence group and non-recurrence group, and the relationships between RT, TTP, mTT, Imax, and enhancement rate of CEUS were analyzed. RESULTS: Among the 128 patients, 23 were highly-differentiated, 63 were moderately-differentiated, and 42 were poorly-differentiated. In addition, there were 31 patients in the recurrence group and 97 patients in the non-recurrence group. RT, TTP, and enhancement rate had significant differences in the highly-differentiated, moderately-differentiated, and poorly-differentiated groups. At the same time, RT and TTP were positively correlated with the differentiation degree, while the enhancement rate was negatively correlated with the differentiation degree. Furthermore, RT, TTP, and enhancement rate were statistically significant for the diagnosis of HCC with high, moderate, and poor differentiation, among which RT had the highest diagnostic accuracy. In the recurrence group, RT, TTP, and Imax were lower than those in the non-recurrence group, and the enhancement rate was greater than that in the non-recurrence group. Moreover, low levels of RT, TTP, and Imax along with positive microvascular invasion (MVI) and poor differentiation were risk factors for HCC recurrence, and there was no significant relationship between the average tumor diameter and HCC recurrence. CONCLUSIONS: CEUS can significantly show the differences between the RT, TTP, and enhancement rate of HCC across different levels of differentiation. It can also predict whether the disease will relapse. Moreover, low levels of RT, TTP, and Imax as well as positive MVI and poor differentiation can cause the recurrence of HCC.

RESUMEN

PURPOSE: To evaluate the effect of transcatheter arterial chemoembolization (TACE) under the guidance of contrast-enhanced ultrasound (CEUS) in patients with advanced hepatocellular carcinoma (HCC). METHODS: One hundred and sixty patients with HCC admitted to Cangzhou Central Hospital from April 2015 to April 2017 were enrolled. The clinical data were retrospectively analyzed. Seventy-five patients who underwent TACE according to CEUS results were selected as the observation group. The remaining 85 cases that underwent digital subtraction augiography (DSA) angiography-guided TACE were selected as the control group and were intravenously infused with 15 mg of Endostar+500 mL of normal saline once a day for 3 consecutive days (Endostar 30 mg was reperfused during the operation). Both groups were re-contrasted at 1 month (T2) and 3 months (T3) to determine whether TACE was performed again. The numbers of TACEs re-performed were recorded. Color Doppler energy imaging was used to observe the neovascularization of the tumor. The changes of serum vascular endothelial growth factor (VEGF) and CRP levels were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS: There were significant differences in the number of TACEs re-performed between the observation group and the control group (p<0.05). The serum VEGF level in the observation group was always lower than that in the control group (p<0.05). CRP levels in the control group showed an upward trend. The serum CRP level in the control group was significantly higher compared to the observation group at T3. The number of grades 0 and 1 neovascularization in the control group was significantly lower than in the observation group. The neovascularization rate of the observation group was significantly higher than the control group; the tumor effective rate of the observation group was not different from that of the control group, but the disease control rate was higher than in the control group. CONCLUSION: CEUS-guided TACE treatment of HCC can effectively inhibit tumor angiogenesis, control tumor progression, and prolong the survival of patients, which is conducive to the prognosis of patients.

RESUMEN

Diagnostic value of ultrasound score, color Doppler ultrasound resistance index (RI) and spiral computed tomography (CT) for ovarian tumors was investigated. In total 224 patients pathologically diagnosed with ovarian tumor after operation in Cangzhou Central Hospital were selected, including 120 patients with benign ovarian tumor and 104 patients with malignant ovarian tumor. Patients with benign and malignant tumors were scored according to the ultrasound scoring criteria. The color Doppler ultrasound examination was performed and the corresponding RI was recorded. At the same time, 64-slice spiral CT was performed, and results were compared with the postoperative pathological diagnosis. Also, the sensitivity, specificity and accuracy of the combined application of the three methods were detected. The RI value of benign ovarian tumor was higher than that of malignant ovarian tumor, displaying statistically significant difference (P<0.05). The sensitivity, specificity and accuracy of the combined application of the three methods were 96.49, 90.91 and 93.75%, respectively. Ultrasound scoring, color Doppler ultrasound RI and 64-slice spiral CT have good diagnostic value for ovarian tumor, and the diagnostic accuracy rate of the combined application is higher. Therefore, different examination methods can be selected in clinic according to the different situations.

RESUMEN

BACKGROUND: This study aimed to evaluate the prognostic value of the combination of serum levels of vascular endothelial growth factor (VEGF), C-reactive protein (CRP), and contrast-enhanced ultrasound (CEUS) in patients with primary liver cancer (PLC) after transcatheter arterial chemoembolization (TACE). METHODS: Overall, 287 PLC patients who had undergone TACE were allocated into recurrence and non-recurrence groups. One day before and seven days after TACE, CEUS was performed, and serum VEGF and CRP levels were determined. All patients were assigned into either a short time-to-radiologic progression (TTRP) group (TTRP ≤ 12 months) or a long TTRP group (TTRP > 12 months). RESULTS: Serum VEGF and CRP levels were higher in the recurrence group than the non-recurrence group after TACE. The sensitivity and specificity of CEUS parameters, serum VEGF and CRP levels, and the three combined, were utilized for the purposes of predicting the postoperative recurrences of PLC, which were 80.9% and 87.8%, 81.7% and 71.5%, 67.0% and 69.8%, and 87.8% and 90.1%, respectively. CONCLUSION: This study demonstrated that high serum levels of both VEGF and CRP in addition to a low time-to-peak (TTP) value in CEUS were indicators for poor prognosis in PLC patients.

RESUMEN

BACKGROUND: China's healthcare reform programme continues to receive much attention. Central to these discussions has been how the various financial incentives underpinning reform efforts are negatively impacting on the healthcare workforce. Research continues to document these trends, however, qualitative analysis of how these incentives impact on the motivation of healthcare workers remains underdeveloped. Furthermore, the application of motivational theories to make sense of healthcare worker experiences has yet to be undertaken. METHODS: The purpose of our paper is to present a comparative case study account of healthcare worker motivation across urban China. It draws on semi structured interviews (n = 89) with a range of staff and organisations across three provinces. In doing so, the paper analyses how healthcare worker motivation is influenced by a variety of financial incentives; how motivation is influenced by the opportunities for career development; and how motivation is influenced by the day to day pressures of meeting patient expectations. RESULTS: The experience of healthcare workers in China highlights how a reliance on financial incentives has challenged their ability to maintain the values and ethos of public service. Our findings suggest greater attention needs to be paid to the motivating factors of improved income and career development. Further work is also needed to nurture and develop the motivation of healthcare workers through the building of trust between fellow workers, patients, and the public. CONCLUSIONS: Through the analysis of healthcare worker motivation, our paper presents a number of ways China can improve its current healthcare reform efforts. It draws on the experience of other countries in calling for policy makers to support alternative approaches to healthcare reform that build on multiple channels of motivation to support healthcare workers.

RESUMEN

OBJECTIVE: To evaluate the impacts on the short-term efficacy and the long-term prevention of recurrence of allergic rhinitis treated with the triple-strong stimulation at Dazhui (GV 14) so as to provide the convenient and long-term effective therapy of acupuncture and moxibustion for allergic rhinitis. METHODS: One hundred and twenty cases of allergic rhinitis were randomized into an acupuncture group, an acupuncture + medication group and a triple-strong stimulation group, 40 cases in each one. In the acupuncture group, acupuncture was applied at Dazhui (GV 14), Fengchi (GB 20), Baihui (GV 20), Yintang (GV 29) and the others, stimulating with reinforcing manipulation for the deficiency and reducing manipulation for the excess, once every day. In the acupuncture + medication group, on the basis of acupuncture therapy, claritin (loratadine tablets) was supplemented for oral administration, 10 mg, once every two days, continuously for 30 days. In the triple-strong stimulation group, on the basis of acupuncture therapy, the strong needling, strong cupping and strong moxibustion were applied at Dazhui (GV 14). This combined therapy was given once every day in the first 3 days and once every two days afterwards. The 10 day treatment made one session, at the interval of 3 days between the sessions and totally 3 sessions were required in the three groups. Separately, before treatment, after treatment and in 6 months after treatment, the changes of symptom and physical sign score and value of single item symptom including nasal itching, nasal blockage, sneezing and rhinorrhea were observed in the patients of the three groups. And the long-term clinical efficacy was compared among the three groups. RESULTS: The symptom and physical sign score and the value of single item symptom were all reduced in the three groups after treatment and in 6 months after treatment (P < 0.001, P < 0.01, P < 0.05). The results in the triple-strong stimulation group were superior to the other two groups (all P < 0.05). In the triple-strong stimulation group, the total effective rate was 92.5% (36/40) in the follow-up of 6 months after treatment, which was better than 60.5% (23/38) in the acupuncture group and 69.2% (27/39) in the acupuncture + medication group (both P < 0.01). CONCLUSION: The combined therapy of acupuncture and the triple-strong stimulation at Dazhui (GV 14) achieves the reliable and effective result in the clinical treatment of allergic rhinitis and displays the good role on the prevention from long-term recurrence.
