ABSTRACT
Objective:To investigate the value of high-frequency ultrasound and shear wave elastography in preoperative evaluation of basal cell carcinoma (BCC) .Methods:A total of 95 patients with histopathologically confirmed cutaneous BCC were enrolled from Department of Dermatology, Hospital of Traditional Chinese Medicine of Zhongshan from January 2017 to December 2020, all of whom had underwent preoperative conventional ultrasonography and shear wave elastography. Conventional ultrasonography parametres including the maximum diameter, maximum infiltration depth, maximum blood flow velocity and resistance index were recorded, so were shear wave elastography parametres including the average Young′s modulus (Eave) , Young′s modulus standard deviation (Esd) and average Young′s modulus ratio (Eratio) . All the patients were divided into high- and low-risk BCC groups according to pathologic subtypes. Paired t-test was used to compare conventional ultrasonography and shear wave elastography findings between the 2 groups. Results:There were 15 cases in the high-risk BCC group and 80 cases in the low-risk BCC group. Compared with the low-risk BCC group, the high-risk BCC group showed significantly increased maximum depth of tumor infiltration (8.5 ± 4.6 mm vs. 4.5 ± 1.6 mm, t = 6.150, P < 0.001) , Eave (32.7 ± 11.2 kPa vs. 20.6 ± 5.1 kPa, t = 4.065, P = 0.001) and Esd (7.0 ± 4.1 kPa vs. 4.2 ± 2.1 kPa, t = 2.632, P = 0.018) , while there were no significant differences in the other measurement data between the two groups (all P > 0.05) . The areas under the receiver operating characteristic curves of the maximum infiltration depth, Eave and Esd for the diagnosis of high-risk BCC were 0.775, 0.909 and 0.822 respectively, and Eave showed the best diagnostic performance. Using 25.7 kPa as the cut-off value, the sensitivity and specificity of Eave were 86.7% and 85.0% for the diagnosis of high-risk BCC, respectively. Conclusion:High-frequency ultrasound and shear wave elastography can facilitate differential diagnosis between high- and low-risk BCC.
ABSTRACT
Objective To investigate the clinical effect of PKP combined with anti osteoporosis drugs in the treatment of osteoporotic vertebral compression fractures.Methods 100 cases of osteoporotic vertebral compression fractures treated in our hospital from January 2014 to December 2016 were compression fracture as the research object in the course of the study, and were randomly divided into control group and experimental group,with 50 cases in each group.Patients in the control group were treated with PKP, while the experimental group was treated with PKP combined with anti osteoporosis drugs.The related clinical indicators of the two groups were compared and analyzed.Results After the corresponding treatment, there was no significant difference between the experimental group and the control group in the rate of cement leakage and the amount of bone cement injection.After operation, the ODI index and VAS scoreof the two groups were significantly better than before treatment, the difference was statistically significant(P<0.05), the patient's cone height was well recovered.After 14 to 24 months of follow-up found that, the fracture rate of the experimental group was 10.0%, significantly lower than the control group 24.0%, the difference was statistically significant(P<0.05).Conclusion PKP combined with anti osteoporosis drugs for the treatment of osteoporotic vertebral compression fractures has good clinical effect, can effectively reduce the adjacent segment cone fracture rate, improve the quality of life of patients, with further clinical promotion and application significance.
ABSTRACT
Objective To study the effect of Bupi-Qufeng decoction on total serum IgE (TIgE) and EOS counts of atopic dermatitis (AD).Methods A total of 101 cases were randomly recruited into a treatment group and a control group.During the treatment both groups were give Danggui-Bohe ointment for external use,and based on this,oral Bupi-Qufeng decoction was added in the treatment group and loratadine in the control group.TIgE level and EOS count were detected both before the treatment and four weeks after the treatment.Results TIgE in the treatment group decreased significantly after the treatment (t=8.0063,P＜0.001),the decreased value of which was larger than the control group (t=3.6434,P＜0.001).EOS count in the treatment group also obviously decreased after the treatment (t=3.0314,P＜0.01) ; the decreased value of which was also larger than the control group (t=3.3331,P＜0.01).Conclnsion Bupi-Qufeng decoction could decrease TIgE and EOS level of AD patient,while the therapeutic mechanism needed further research.
