ABSTRACT
ObjectiveTo explore the application law of compound prescriptions containing Coptidis Rhizoma to diabetes and its complications based on data mining. MethodA total of 288 records on formulas containing Coptidis Rhizoma in the treatment of diabetes and its complications and the corresponding syndromes and symptoms were retrieved from the medical records of modern physicians， with 218 on the treatment of diabetes and 70 on the treatment of diabetes complications. The Traditional Chinese Medicine Inheritance Computing Platform （V3.0） was used or data mining on the compositions of the formulas. Moreover， it was employed for the frequency statistics， formula analysis， symptom analysis， association rules analysis， network visualization， and cluster analysis. ResultThe 218 formulas containing Coptidis Rhizoma for the treatment of diabetes involved 190 Chinese medicinals. A total of 12 syndromes showed the occurrence frequency ≥ 6， and the one with the highest frequency was deficiency of both qi and yin， followed by the syndrome of excessive heat in lung and stomach， syndrome of Yin deficiency and effulgent fire， and syndrome of excessive heat and fluid consumption. The dose of Coptidis Rhizoma for the treatment of diabetes ranged from 1.5-30 g， and the most frequently used doses were 10， 6， and 5 g. The medicinal was frequently applied for the traditional Chinese medicine symptoms of dry stool， dry mouth and tongue， and swift digestion with rapid hungering. Moreover， 26 core medicinal pairs， 17 association rules， 3 diagrams on medicinal relationship， and 3 core combinations were yielded. The 70 formulas containing Coptidis Rhizoma for the treatment of diabetes complications involved 184 Chinese medicinals， and the top 3 complications were diabetic nephropathy， diabetic peripheral neuropathy， and diabetic gastroenteropathy. The dose of Coptidis Rhizoma in the treatment of diabetes complications fell in the range of 2-15 g， and 10， 6， and 5 g were most frequently used. ConclusionFormulas containing Coptidis Rhizoma for the treatment of diabetes and its complications mainly target the syndrome of dampness-heat transforming into fire and the syndrome of excessive heat damaging yin. This study can serve as a reference for standard use of Coptidis Rhizoma in the prevention and treatment of diabetes and its complications.
ABSTRACT
Objective@#The present study was conducted to investigate the response of peroxiredoxin 3 (PRX3) to oxidative stress induced by high-risk human papillomavirus (HPV).@*Methods@#Sixty patients with cervical cancer were included and sixty patients with hysteromyoma were assigned as controls. Serum PRX3 was detected by enzyme-linked immunosorbent assay. The expression of PRX3 and oncoprotein E6 of HPV16 or HPV18 was examined in cervical cancer tissues by immunohistochemistry and in cervical cancer cells by Western blotting respectively.@*Results@#Patients with invasive squamous cervical cancer showed higher level of serum PRX3 than control subjects with hysteromyoma. PRX3 expression was up-regulated and was positively associated with that of E6 of HPV16 or HPV18 in cervical cancer tissues. The correlation was confirmed in HPV-containing cervical cancer cell lines including CaSki, and HeLa.@*Conclusions@#Our result indicated a positive response of PRX3 to HPV-induced oxidative stress. Serum PRX3 might be a potential indicator of active amplification of high-risk HPV in cervical cancer cells.
