Multidrug resistance (MDR) is one of the main causes leading to the failure in cancer treatment. Differential proteins between esophageal squamous cell carcinoma (ESCC) cell line EC9706 and its cisdiamminedichloroplatinum (CDDP)-resistant subline EC9706/CDDP revealed by quantitative analysis may provide deeper insights into the molecular mechanisms of MDR implicated in ESCC. EC9706/CDDP was generated by exposure of its parental sensitive EC9706 to a step-wise increase of CDDP concentration during EC9706 cultivation. The stable isotope labeling with amino acids in cell culture (SILAC) was used to label EC9706 and EC9706/CDDP with heavy and light medium, separately. Mixed peptides derived from EC9706 and EC9706/CDDP were analyzed by high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS/MS) and subsequently subjected to bioinformatics analysis to identify differential proteins between EC9706 and EC9706/CDDP. Compared to parental EC9706, EC9706/CDDP manifested phenotypes of slow proliferation, cell pleomorphology, atypia and increased resistant-index 3.23. Seventy-four differential proteins identified in the present study belongs to various families with multiple functions, such as cytoskeleton (20%), energy metabolism (11%), transcription regulation and DNA repair (11%), redox homeostasis (9.5%), protein biosynthesis and mRNA processing (12%), ribosome constituent (8.1%), molecular chaperone (8.1%), immunity/inflammation (5.4%), intracellular transport (5.4%) and nucleosome assembly (2.7%), which indicated that development of MDR is a complicated process involving dysregulation of multiple molecules and pathways. The data is of great value for in-depth elucidation of molecular mechanisms of the MDR implicated in ESCC and may represent potential molecular targets for future therapeutic development.

OBJECTIVETo investigate the technique for unilateral cleft lip nasal deformities.

METHODSThrough the traditional columella margin incision, the alar cartilage and the lateral nasal cartilage were exposed. After the mucosa between the two cartilages was divided, a mucosa-cartilage flap was developed and anchored, moving the lateral crus upwardly and medially, correcting the nasal deformity.

RESULTS52 cases of primary nasal deformities and 18 cases of secondary nasal deformities were corrected with this technique. Satisfactory results were achieved.

CONCLUSIONThis technique is recommendable, which is more likely to restore the physiological characters of the nose than the conventional technique.

Objective:To compare the clinical effects of endoscope-assisted and direct prosthetic augmentation mammaplasty through inframammary fold incisions.Methods:The clinical data of patients who underwent prosthetic augmentation mammaplasty through inframammary fold incisions in Chongqing Huamei Plastic Surgery Hospital from June 2021 to October 2022 were collected. At the same time, the clinical data of patients who underwent the operation under direct vision from June 2015 to May 2021 were collected as control group. The operation time, postoperative drainage tube indwelling time, length of hospital stay and postoperative drainage volume within 1-3 days were recorded in the two groups, and the incision healing, breast morphology and complications were collected. The data were processed by SPSS 26.0 software, which accorded with the measurement data of normal distribution with Mean ± SD, and t-test was used for comparison between the two groups. The data were presented as frequency and (or) percentage, and Fisher’s exact test was used for comparison between the two groups. When P < 0.05, the difference was considered statistically significant. Results:A total of 169 female patients aged 21-48 years old were enrolled, including 71 patients in the endoscope-assisted group and 98 patients in the direct group. There was no significant difference in age, body mass index, prosthesis volume and postoperative follow-up time between the two groups ( P > 0.05). The operation process of the two groups was smooth, and the incisions healed by first intention after the operation. The operation time in the endoscope-assisted group was (123.5±13.5) min, which was slightly longer than that in the direct group [(111.5±8.1) min] ( t=7.20, P<0.001), and the postoperative drainage tube indwelling time[(2.6 ±0.7) d)] was significantly shorter than that in the direct group [(4.2±1.0) d] ( t=-11.58, P < 0.001). The length of hospital stay in the endoscope-assisted group [(2.8±0.8) d] was significantly shorter than that in the direct group [(4.6±1.3) d] ( t=-10.33, P < 0.001). The total amount of bilateral drainage in the endoscope-assisted group was (151.0±30.1) ml on the 1st to 3rd day after the operation, which was significantly lower than that in the direct group[(265.0±48.1) ml ] ( t=-17.62, P < 0.001). During the follow-up for one year, the breast shape and hand feeling of the two groups were good, and there was no infection, prosthesis rupture, displacement or exposure. The patients were satisfied with the results of the operation. The rates of capsular contracture, nipple-areola hypoesthesia and scar hyperplasia in the endoscope-assisted group were 0.7% (1/138), 0.7% (1/138) and 0 (0/138), respectively, which were lower than those in the direct group [2.7%(5/188), 3.7%(7/188) and 2.7%(5/188)], respectively, but the differences were not statistically significant ( P > 0.05). Conclusion:Both endoscope-assisted and direct prosthetic augmentation mammaplasty through an inframammary fold incision can achieve satisfactory results. The operation time of endoscope-assisted augmentation mammaplasty is slightly longer than that under direct vision, but the surgical trauma of that is less, the postoperative drainage tube indwelling time and length of hospital stay are shortened, and the amount of bleeding in the operation area is reduced.
