Objective To explore the diagnostic value of liquid-based cytology combined with squamous cell carcinoma antigen (SCCA) and cancer antigen 153 (CA153) detection in patients with cervical cancer. Methods Liquid-based cytology, serum SCCA, and serum CA153 were detected on 54 patients with cervical intraepithelial neoplasia (neoplasia group), 54 patients with cervical cancer (cancer group), and 54 healthy subjects (control group). Pathological biopsy diagnosis was used as the gold standard. The diagnostic value of liquid-based cytology, serum SCCA, and serum CA153 in cervical cancer was analyzed, and the clinical value of combining liquid-based cytology with serum SCCA and serum CA153 detection was also analyzed. Results The levels of serum SCCA and CA153 in neoplasia group and cancer group were higher than those in control group, and the serum SCCA and CA153 levels in the cancer group were higher than those in the neoplasia group (P<0.05). In the single detection, the positive rate of liquid-based cytology was higher than that of serum SCCA and CA153, and the positive rate of combined detection was significantly higher than those of the single detection (P<0.05). Conclusions Cervical cancer patients have high levels of serum SCCA and CA153. Liquid-based cytology combined with SCCA and CA153 detection has high positive rate for early cervical cancer.

Objective To investigate the effects of different concentrations of sinomenine on proliferation, cell cycle and apoptosis of renal carcinoma cells. Methods The renal carcinoma cells were treated with different concentrations of sinomenine. MTS was used to analyze the effects of sinomenine on proliferation in 786-O renal carcinoma cells, the cell cycle changes were determined using flow cytometry, while the changes of apoptosis were detected by Annexin V-FITC / PI double staining. The expression of apoptosis-related proteins such as c-myc, Bax and Caspase-3 were detected by Western blot. Results Sinomenine significantly inhibited the proliferation of 786-O cells and induced cell cycle arrest and apoptosis in G1/S phase. With the increase of sinomenine concentration, the inhibition rate increased gradually. Sinomenine significantly down-regulated the expression of c-myc protein, while the expressions of the apoptotic protein Bax, Caspase-3 were up-regulated. Conclusions Sinomenine can significantly inhibit the expression of c-myc in 786-O cells, reduce proliferation ability, and induce cell cycle arrest and apoptosis. Sinomenine may have a potential therapeutic effect on renal cancer.

Methods Screening patients with advanced TNBC by searching the SEER (surveillance, epidemiology, and end results) database, using univariate and multivariate analysis to determine the independent prognostic factors of advanced TNBC, and constructing a nomogram based on it. Results A total of 4 687 patients with advanced TNBC were included. Compared with other types of breast cancer over the same period, TNBC had the worst prognosis.
