Cancer is a highly deadly disease, with breast cancer, cervical cancer, endometrial cancer, and ovarian cancer being the most prevalent in women. However, traditional cancer treatments present challenges due to their strong toxic side effects and adverse reactions. Numerous studies have demonstrated that natural products derived from various plants possess therapeutic and preventive properties against cancer. These phytochemicals have been extensively investigated as a potential alternative to conventional chemotherapy drugs, owing to their safety and efficacy. This article provides a comprehensive review of the recent advances in the chemoprevention and mechanisms of phytochemicals against the four major female cancers. The focus will be on how these phytochemicals regulate cancer cell proliferation, apoptosis, invasion, and metastasis to impede cancer progression. Given their extensive clinical applications, phytochemicals hold great promise in the field of cancer treatment. It hopes that this review will inspire more researchers to explore the potential of these natural compounds in combating female cancers.

Objective:To explore the clinical significance of the dominant B-cell epitope peptide of the human cytomegalovirus (HCMV) UL95 gene, as well as the correlation between the plasma UL95 specific antibody levels and clinical indicators in systemic lupus erythematosus (SLE) patients, in order to find auxiliary diagnostic indicators for SLE.Methods:A non-randomized control study was conducted to analyze the sequencial characteristics and polymorphisms of HCMV UL95 gene, and bioinformatics analysis and chemical synthesis were used to synthesize UL95 dominant B cell epitope short peptides, which were used as coating antigens. Enzyme-linked immunosorbent assay (ELISA) assay was used to detect the specific antibody levels of plasma UL95 of 97 SLE patients and 35 healthy controls (HC). Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of UL95 short peptide antibodies for SLE diagnosis. Pearson correlation test was used to analyze the correlation between UL95 specific antibody levels and clinical indicators in SLE patients.Results:The nucleotide sequence similarity of UL95 gene was 92.9%-100%, and the amino acid sequence similarity was 92.1%-100%, whose sequences were highly conserved and homologous. A comprehensive prediction of multiple parameters resulted in 6 possible dominant B cell epitopes, named (Bp1, Bp2, Bp3, Bp4, Bp5, Bp6) respectively. The ELISA results showed that the levels of plasma UL95 specific antibodies (0.35±0.12) in SLE patients were significantly higher than those of the HC group (0.28±0.10)( t=3.091, P=0.002). The area under the ROC curve for distinguishing SLE and HC was 0.703, with a sensitivity of 54.6% and a specificity of 88.6%. In addition, the UL95 specifific antibody levels ( OD value) in the middle-high activity subgroup (systemic lupus erythematosus disease activity index, SLEDAI≥4) were higher (0.36±0.10) than those in the low activity subgroup (SLEDAI<4)(0.30±0.07) ( t=?2.055, P=0.044). UL95 specific antibody levels were positively correlated with clinical indicators such as total immunoglobulin G (IgG) and total immunoglobulin M (IgM), while negatively correlated with complement component 3 (C3), complement component 4 (C4), and platelet count. Conclusions:The antibody level of UL95 is closely related to the activity of lupus disease. The Bp1 (10-21) peptide segment of UL95 has important significance for the auxiliary diagnosis of SLE and is expected to become a new reference indicator.

Objective To explore the influence of home nursing intervention on the adverse events and the ability of caregivers in cerebrovascular disease nasal patients with indwelling gastric tube. Methods Totals of 63 cases with nasal feeding discharge from September 2011 to August 2012 from our department were selected as the control group and 68 cases with nasal feeding discharge from September 2012 to August 2013 from our department were selected as the intervention group. The general information of patients in two groups, the incidence of nasal mucosa mechanical injury and the complications of indwelling gastric tube were retrospectively analyzed. The relevant knowledge and ability of caregivers were compared. Results The incidences of gastric tube out, reflux and aspiration, blocking tube, the nasal mucosa mechanical injury, the complications of constipation, diarrhea, gastric retention, malnutrition in the intervention group were 7. 4%, 0. 0%, 0. 0%, 2. 9%, 2. 9%, 23. 5%, 41. 2%, 14. 7% and 14. 7%, respectively. Those incidences in the control group were 30. 1%, 36. 5%, 36. 5%, 25. 3%, 23. 8%, 58. 7%, 71. 4%, 41. 3% and 36. 5%, respectively. The incidences of adverse events of the intervention group were significantly lower than those of the control group (χ2 =11. 37, 30. 11, 30. 11, 13. 91, 12. 61, 16. 82, 9. 41, 11. 58, 8. 25, respectively;P <0. 05). The extent of gaining the relevant knowledge and the ability of caregivers in the intervention group were 91. 2%, 88. 2% and 85. 3%, respectively. Those incidences in the control group were 52. 4%, 41. 3% and 55. 6%, respectively. The incidences of the intervention group were significantly higher than those of the control group (χ2 =24. 70, 31. 99, 14. 04, respectively;P <0. 01). Conclusions The home nursing intervention can improve the treatment compliance of patients and the ability of family caregivers. It can also avoid and reduce the occurrence of adverse events, therefore it can enhance the quality of life of the patients.

RNA interference (RNAi) is useful for selective gene silencing. Cytochrome P450 3A4 (CYP3A4), which metabolizes approximately 50% of drugs in clinical use, plays an important role in drug metabolism. In this study, we aimed to develop a short hairpin RNA (shRNA) to modulate CYP3A4 expression. Three new shRNAs (S1, S2 and S3) were designed to target the coding sequence (CDS) of CYP3A4, cloned into a shRNA expression vector, and tested in different cells. The mixture of three shRNAs produced optimal reduction (55%) in CYP3A4 CDS-luciferase activity in both CHL and HEK293 cells. Endogenous CYP3A4 expression in HepG2 cells was decreased about 50% at both mRNA and protein level after transfection of the mixture of three shRNAs. In contrast, CYP3A5 gene expression was not altered by the shRNAs, supporting the selectivity of CYP3A4 shRNAs. In addition, HepG2 cells transfected with CYP3A4 shRNAs were less sensitive to Ginkgolic acids, whose toxic metabolites are produced by CYP3A4. These results demonstrate that vector-based shRNAs could modulate CYP3A4 expression in cells through their actions on CYP3A4 CDS, and CYP3A4 shRNAs may be utilized to define the role of CYP3A4 in drug metabolism and toxicity.

Objective To investigate the long-term outcome of children with recurrent wheeze and to determine the effectiveness of inhaled hormone therapy. Methods One thousand and thirty-five children with recurrent wheezing were followed up for more than 4 years and the data were retrospectively evaluated. Results Of 1035 cases, 751 (72.56%) patients outgrew their wheeze during the follow-up period, whereas the other 284 (27.44%) patients had recurrence wheeze during the last two years. The age of wheezing onset was<3 years in 542 (52.37%) cases, from 3 to 7 years in 386 (37.29%) cases, and from 7 to 12 years in 107 (10.34%) cases. There was significant difference in clinical control rate among groups with different wheezing ages onset (χ2=45.27, P<0.001). Children with wheezing age onset from 7 to 12 years had the lowest clinical control rate. Among 1035 wheeze children, 343 (79.95%) children in 429 cases who received inhaled hormone therapy for more than one year outgrew their wheeze. Whereas 408 (67.35%) in 606 cases who did not receive inhaled hormone therapy outgrew their wheeze. There was significant difference of clinical control rate between inhaled group and non-inhaled group (P<0.01). Con-clusions The age of wheezing onset is<7 years in 89.66%of children with recurrent wheeze. Most of them can be clinicalycon-trolled. The long term inhaled hoemone therapy for children with recurrent wheeze can reduce the risk of developing adulthood asthma.
