Effects of evidence-based nursing care interventions on wound pain and wound complications following surgery for finger tendon injury.

We conducted this study aimed to examine the impact of evidence-based nursing interventions on postoperative wound pain and complications after surgery for finger tendon injury. A total of 86 patients treated for finger tendon injuries at our hospital from January 2021 to October 2023 were selected and randomly divided into an experimental group and a control group. The control group received conventional nursing care, while the experimental group received evidence-based nursing interventions. The study compared the postoperative wound pain intensity, incidence of complications and patient satisfaction with nursing care between the two groups. The analysis revealed that compared with conventional care, evidence-based nursing interventions significantly reduced the level of wound pain (p = 0.034) and the incidence of complications (4.65% vs. 18.60%, p = 0.043). It also increased patient satisfaction with the nursing care (97.67% vs. 83.72%, p = 0.026). The study indicates that the application of evidence-based nursing interventions for patients with finger tendon injuries can reduce postoperative wound pain, decrease the incidence of complications and enhance patient satisfaction with nursing care.

[Effects of Brucea javanica oil emulsion on human papilloma virus type 16 infected cells and mechanisms research].

OBJECTIVE: To explore the in vitro inhibitive effect and underlying mechanisms of Brucea Javanica oil emulsion (BJOE) on human papilloma virus (HPV) type 16 infected cells. METHODS: The HPV16 E61E7 immortalized human ectocervical Ect1/E6E7 cell line and the CaSki cell line were selected as the in vitro models of premalignant cervical lesion and cervical cancer respectively. After treated with BJOE at different concentrations (5, 10, 20, and 40 microg/mL) at the operation time points (24, 48, and 72 h), the effects of BJOE on proliferative activities were measured by MTT assay. The morphologic changes of cell apoptosis stained with Hochest 33,258 were observed by fluorescence microscope. The effect on the cell apoptosis rate was analyzed by Annexin V-FITC/PI double-labeled flow cytometry. The mRNA expressions of HPV16 E6 and E7 were determined by semi-quantitative RT-PCR. The protein expressions of HPV16 E6, E7 oncogene, and specifically interacted p53, Rb antioncogene were stained by immunocytochemical staining (Elivison two-step procedure). RESULTS: (1) The proliferative activities of the Ect1/E6E7 cell and the CaSki cell treated with BJOE at different concentrations (5, 10, 20, and 40 p g/mL) at the operation time points (24, 48, and 72 h) were obviously inhibited, showing dose- and time-dependent manners (P <0.05). (2) Typical changes of apoptosis were observed in both HPV 16 positive cell lines after treated with BJOE. The cell apoptosis rates increased markedly after being cultured with BJOE at different concentrations (5, 10, and 20 microg/mL) for 48 h (P < 0.05). (3) After treated with BJOE at different concentrations (5, 10, and 20 microg/mL) for 48 h, the HPV16 E6 and E7 mRNA relative expressions in both HPV 16 positive cell lines decreased significantly (P < 0.05). (4) After treated with BJOE at different concentrations (5, 10, and 20 microg/ mL), the expressions of HPV16 E6, E7, and mutant p53 protein decreased gradually (P < 0.05), while the Rb protein expression increased gradually (P < 0.05). CONCLUSIONS: BJOE showed obvious in vitro inhibitory effects on HPV type 16 infected cells. Its underlying mechanisms might be possibly associated with down-regulating expressions of HPV16 E6 and E7 oncogenes.
