To explore the stability of Shenkang injection respectively in five different solutions to choose the best com-patibility program and improve the rational drug use. Methods:The pH value, insoluble particles and the content of protocatechuic al-dehyde in Shenkang injection were determined after mixed with five solutions. Results:In the 6-hour mixing, the change order of proto-catechuic aldehyde content was 0. 9% sodium chloride injection> 5% fructose injection> 10% invert sugar injection > 5% dextrose injection> 10% glucose injection, especially in 0. 9% sodium chloride injection, the content was decreased by 20%. The number of insoluble particles was increased after the 2-hour mixing except in 10% invert sugar injection solution, and the increase in the four so-lutions was beyond the requirement in the 2010 edition of Chinese Pharmacopoeia, and the number of insoluble particles in 0. 9% sodi-um chloride injection was the highest with the fastest change. During the experimental process, the pH value was stable. Conclusion:The five solutions show influence on stability of Shenkang injection in varying degrees. Shenkang injection in 0. 9% sodium chloride in-jection is the least stable, which should be used with caution in clinics, while invert sugar injection and glucose injection can be the best choice for Shenkang injection and the mixed solution should be used up in 2h.

Objective:To investigate the expression and clinical significance of long non-coding RNA (LncRNA) CRNDE in cer-vical cancer. Methods:Specimens of cervical cancer tissues and matched non-tumor para-neoplastic tissues were collected from 87 pa-tients who underwent surgery in the Kaiping Central Hospital, China. Quantitative real-time PCR was used to examine the expression of LncRNA CRNDE, and its correlation with clinicopathological features was analyzed. Results:LncRNA CRNDE expression was sig-nificantly up-regulated in cervical cancer tissues than in adjacent non-tumor tissues (P<0.05). Increased LncRNA CRNDE expression was significantly correlated with FIGO stage, lymph node metastasis, and depth of cervical invasion (P<0.05). Moreover, a higher ex-pression of LncRNA CRNDE demonstrated significantly poorer overall survival in cervical cancer patients than in those with lower Ln-cRNA CRNDE expression (P<0.05). Multivariate analyses suggested that LncRNA CRNDE expression served as an independent pre-dictor for overall survival. Conclusion:Our findings posit that LncRNA CRNDE may be a potential prognostic marker and therapeutic target for cervical cancer.
