Triple-negative breast cancer (TNBC) represents a distinctive subtype, characterized by the absence of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 (HER2). Due to its high inter-tumor and intra-tumor heterogeneity, TNBC poses significant chanllenges for personalized diagnosis and treatment. The advant of clustered regular interspaced short palindromic repeats (CRISPR) technology has profoundly enhanced our understanding of the structure and function of the TNBC genome, providing a powerful tool for investigating the occurrence and development of diseases. This review focuses on the application of CRISPR/Cas technology in the personalized diagnosis and treatment of TNBC. We begin by discussing the unique attributes of TNBC and the limitations of current diagnostic and treatment approaches: conventional diagnostic methods provide limited insights into TNBC, while traditional chemotherapy drugs are often associated with low efficacy and severe side effects. The CRISPR/Cas system, which activates Cas enzymes through complementary guide RNAs (gRNAs) to selectively degrade specific nucleic acids, has emerged as a robust tool for TNBC research. This technology enables precise gene editing, allowing for a deeper understanding of TNBC heterogeneity by marking and tracking diverse cell clones. Additionally, CRISPR facilitates high-throughput screening to promptly identify genes involved in TNBC growth, metastasis, and drug resistance, thus revealing new therapeutic targets and strategies. In TNBC diagnostics, CRISPR/Cas was applied to develop molecular diagnostic systems based on Cas9, Cas12, and Cas13, each employing distinct detection principles. These systems can sensitively and specifically detect a variety of TNBC biomarkers, including cell-specific DNA/RNA and circulating tumor DNA (ctDNA). In the realm of precision therapy, CRISPR/Cas has been utilized to identify key genes implicated in TNBC progression and treatment resistance. CRISPR-based screening has uncovered potential therapeutic targets, while its gene-editing capabilities have facilitated the development of combination therapies with traditional chemotherapy drugs, enhancing their efficacy. Despite its promise, the clinical translation of CRISPR/Cas technology remains in its early stages. Several clinical trials are underway to assess its safety and efficacy in the treatment of various genetic diseases and cancers. Challenges such as off-target effects, editing efficiency, and delivery methods remain to be addressed. The integration of CRISPR/Cas with other technologies, such as 3D cell culture systems, human induced pluripotent stem cells (hiPSCs), and artificial intelligence (AI), is expected to further advance precision medicine for TNBC. These technological convergences can offer deeper insights into disease mechanisms and facilitate the development of personalized treatment strategies. In conclusion, the CRISPR/Cas system holds immense potential in the precise diagnosis and treatment of TNBC. As the technology progresses and becomes more costs-effective, its clinical relevance will grow, and the translation of CRISPR/Cas system data into clinical applications will pave the way for optimal diagnosis and treatment strategies for TNBC patients. However, technical hurdles and ethical considerations require ongoing research and regulation to ensure safety and efficacy.

AIM: To observe changes in fundus microcirculation of myopic adolescents after wearing orthokeratology by applying optical coherence tomography angiography(OCTA).METHODS: Prospective study. A total of 40 cases(40 eyes)of adolescents with low to moderate myopia who chose orthokeratology to correct visual acuity at our hospital from April 2021 to June 2022 were collected. The uncorrected distant visual acuity and axial length were evaluated at 1, 3 and 6mo before and after wearing orthokeratology, respectively. Furthermore, the changes in superficial vessel density(SVD), deep vessel density(DVD), central retinal thickness(CRT), foveal avascular zone area(FAZ-A), foveal avascular zone perimeter(FAZ-P), retinal nerve fiber layer(RNFL)thickness and radial peripapillary capillaries density(RPCD)were observed by applying OCTA.RESULTS: The uncorrected distant visual acuity was significantly improved at 1, 3 and 6mo after wearing orthokeratology(P<0.001). There was no statistically significant difference in axial length before and after wearing orthokeratology(P>0.05). Moreover, there were significant differences in both SVD of fovea quadrant and DVD of fovea and lower quadrant(P<0.01), but there were no differences in CRT, FAZ-A and FAZ-P, RNFL thickness and RPCD(P>0.05).CONCLUSION: Wearing orthokeratology can significantly improve visual acuity and increase local retinal vessel density in the macula in adolescents with low to moderate myopia.

The purpose of this study was to evaluate the diagnostic performance of multiparametric ultrasound (mpUS; grayscale US, color Doppler US, strain elastography, and contrast-enhanced US) in the assessment of testicular lesions with negative tumoral markers. MpUS imaging data, patient age, serum tumor markers, scrotal pain, cryptorchidism, and related clinical information were retrospectively collected for patients who underwent mpUS examination between January 2013 and December 2019. Histologic results or follow-up examinations were used as the reference standard. In total, 83 lesions from 79 patients were included in the analysis. Fifty-six patients were finally diagnosed with benign tumors, and 23 patients were ultimately diagnosed with malignant tumors. Chi-square tests or Fisher's exact tests were used to assess the difference between the two groups. Stepwise multivariate logistic regression analysis showed that lesion diameter (odds ratio [OR] = 1.072, P = 0.005), vascularization on color Doppler US (OR = 4.066, P = 0.001), and hyperenhancement during the early phase (OR = 6.465, P = 0.047) were significant independent risk factors for malignancy; however, when compared with neoplastic lesions, pain (OR = 0.136, P < 0.001), absence of vascularization on color Doppler US (OR = 1.680, P = 0.042), and nonenhancement during the late phase (OR = 3.461, P = 0.031) were strongly associated with nonneoplastic lesions. MpUS features are useful for differentiating testicular lesions with negative tumoral markers and improving the preoperative diagnosis, which may avoid inappropriate radical orchiectomy.

OBJECTIVE:
To investigate the influece of early relapse in the era of novel drugs on the prognosis of the patients with newly diagnosed multiple myeloma(NDMM) and risk factors, and to provide the basis for the early identification of the high-risk patients and guiding the treatment.
METHODS:
The clinical data of the patients with NDMM admitted to our hospital from November 2011 to May 2022 were retrospectively analyzed. According to whether the progression free survival(PFS) was more than 12 months, they were divided into early relapse group(≤12 months) and late relapse group(>12 months). The high-risk factors of the patients in two groups were analyzed, including age, anemia, renal insufficiency, hypercalcemia, increasing of lactate dehydrogenase(LDH) level, Extramedullary disease (EMD), International Staging System(ISS) stage, Revised International Staging System (R-ISS) stage, cytogenetic abnormalities(CA) detected by fluorescence in situ hybridization(FISH), and treatment efficacy. The meaningful clinical indicators were screened, and multivariate analysis was used to explore the high-risk factors of early relapse.
RESULTS:
170 patients with NDMM were collected, including 25 cases in early relapse group and 145 cases in late relapse group. The median OS time of the patients in early death group was 20 months, and 140 months in late relapse group by the end of follow-up, there was significant difference in OS of the patients between two groups(P<0.001). Fifteen patients(56.0%)in early relapse group obtained ≥VGPR, and 113(77.9%) patients in late relapse group, the difference was statistically significant(P=0.011). Survival outcomes remained poor among early relapse patients irrespective of depth of response to initial therapy. Multivariate analysis showed that the EMD and high-risk CA predicted early relapse.
CONCLUSION
The prognosis of patients with early relapse in NDMM is poor. EMD and high-risk CA is an independent prognostic factor of early relapse.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
