Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

Wnt/β-catenin is a signaling pathway associated with embryonic development, organ formation, cancer, and fibrosis. Its activation can repair kidney damage during acute kidney injury (AKI) and accelerate the occurrence of renal fibrosis after chronic kidney disease (CKD). Interestingly, p53 has also been found as a key modulator in AKI and CKD in recent years. Meantime, some studies have found crosstalk between Wnt/β-catenin signaling pathways and p53, but more evidence is required on whether they have synergistic effects in renal disease progression. This article reviews the role and therapeutic targets of Wnt/β-catenin and p53 in AKI and CKD and proposes for the first time that Wnt/β-catenin and p53 have a synergistic effect in the treatment of renal injury.

Objective:To investigate the application value of single-sperm sequencing in resolving the carrier status of preim-plantation genetic testing(PGT)for chromosomal structural rearrangements in Robertsonian translocations.Methods:Haplotypes were constructed by single-sperm isolation combined with single-sperm sequencing for a patient with 45,XY,der(13;14)(q10;q10).Twenty single-sperm samples were isolated by mechanical braking and subjected to whole-genome amplification(WGA),and then the Asian Screening Array(ASA)gene chip was used to detect the 183 708 single nucleotide polymorphisms(SNP)of the WGA products.The single sperm associated with the translocation that could be used as haplotype inference was detected by copy number variation(CNV)sequencing,and the chromosomal haplotypes with normal and Robertsonian translocations were inferred.Three biopsy samples of embryonic trophoblast cells were used as the objects.After whole-genome amplification,high-throughput sequencing was employed to determine the status of the translocation chromosome carried by the embryos.The available blastocysts were selected for transfer,and the amniotic fluid samples were taken at 18 weeks of gestation to confirm whether the fetus carried the pathogenic muta-tion.Results:A total of 6 037 SNP sites were screened by single-sperm sequencing,and 30 sites selected to distinguish normal and translocation haplotypes.Preimplantation haplotype analysis showed that all the three embryos were euploids without Robertsonian translocation chromosome.Genetic testing of amniotic fluid in the second trimester confirmed that the karyotype of the fetus was 46,XN,carrying no Robertsonian translocation chromosome.Conclusion:For male carriers of Robertsonian translocation,single sperm sequencing can be used to screen SNP sites to construct haplotypes for distinguishing normal and Robertsonian translocation em-bryos,and to provide a basis for embryo selection by preimplantation chromosomal structural genetic testing.

Objective:To explore the effect of combining hand-brain perception training with hand-brain motor training based on mirror neuron theory on the recovery of upper limb function after a stroke.Methods:A group of 105 stroke survivors with upper limb dysfunction were randomly divided into a hand-brain perception (HP) group, a hand-brain motor (HM) group, and a combination (C) group, each of 35. In addition to conventional rehabilitation treatment (including exercise therapy, occupational therapy and physical factor therapy), the HP and HM groups were given hand-brain perception training and hand-brain motor training respectively, while group C was provided with both. Before the intervention and after 4 weeks, the upper limb motor functioning of all of the participants was assessed using the simplified version of the Fugl-Meyer upper limb motor function scale (FMA-UE). Sensory functioning was quantified using the tactile Semmes Weinstein monofilament examination (SWME), and the modified Barthel index (MBI) was used to quantify the participants′ ability in the activities of daily living.Results:After the intervention the average FMA-UE, MBI and SWME scores of all three groups had improved significantly, with group C′s average FMA-UE and MBI scores significantly better than the other two groups′ averages. The average SWME score of group C was then significantly better than that of group HM.Conclusions:Hand-brain perception combined with hand-brain motor training based on mirror neuron theory can further promote the recovery of upper limb sensory and motor functioning of stroke survivors., Such therapy is worthy of clinical promotion and application.

Objective:To explore the diagnostic value of improved 18F-prostate specific membrane antigen (PSMA)-1007 PET-CT score (referred to as PSMA score) and multi parameter magnetic resonance imaging (mpMRI) prostate imaging reporting and data system (PI-RADS) score (referred to as PI-RADS score) for primary prostate cancer (PCa). Methods:A retrospective case series study was conducted. The imaging and clinical data of 134 suspected PCa patients underwent 18F-PSMA-1007 PET-CT and mpMRI examinations at Shanxi Province Cancer Hospital from July 2018 to May 2023 were collected. Pathological diagnosis showed 92 cases of PCa and 42 cases of benign prostatic lesions. The clinical and imaging parameters, as well as the distribution of patients with two scores, were compared between the two groups. The blind diagnosis of benign and malignant lesions was made based on the improved PSMA score (dividing 1 point into 1a and 1b points, 1b, 2 and 3 points were diagnosed as PCa), PI-RADS score (3, 4 and 5 points were diagnosed as PCa) and the combination of the two (diagnosed as PCa when either PSMA score ≥ 1b point or PI-RADS score ≥ 4 points was met). The indicators of the diagnostic efficiency of PSMA score, PI-RADS score and the combination of the two for PCa were calculated. Using pathological results as the gold standard, the receiver operating characteristic (ROC) curve of PSMA score, PI-RADS score and the combination of the two for diagnosing PCa was drawn, and the diagnostic efficiency of the 3 methods was analyzed. Results:The age, serum prostate-specific antigen, and maximum standard uptake value of PET-CT in the PCa group were higher than those in the benign prostatic lesion group, and the differences were statistically significant (all P < 0.05). The sensitivity, specificity, accuracy, false negative rate, false positive rate, positive predictive value, and negative predictive value of PSMA score for diagnosing PCa were 91.30% (84/92), 80.95% (34/42), 88.06% (118/134), 8.70% (8/92), 19.05% (8/42), 91.30% (84/92), and 80.95% (34/42), respectively; those of PI-RADS score were 93.48% (86/92), 61.90% (26/42), 83.58% (112/134), 61.90% (26/42), 38.10% (16/42), 84.31% (86/102), and 81.25% (26/32), respectively; those of the combination of the two were 97.83% (90/92), 88.10% (37/42), 94.78% (127/134), 2.17% (2/92), 11.90% (5/42), 94.74% (90/95), and 94.87% (37/39), respectively. The differences in specificity, accuracy, false negative rate, and false positive rate among the 3 methods were statistically significant (all P < 0.05). ROC curve analysis showed that the area under the curve of PSMA score, PI-RADS score and the combination of the two for diagnosing PCa were 0.930 (95% CI: 0.872-0.967), 0.935 (95% CI: 0.826-0.939) and 0.959 (95% CI: 0.910-0.986), respectively, and the differences between each two methods were statistically significant (all P < 0.05); the sensitivity of PSMA score, PI-RADS score and the combination of the two was 90.11%, 89.13% and 98.09%, and the specificity was 90.48%, 90.48% and 92.09%. Conclusions:Compared with the PI-RADS score, the improved PSMA score can improve the specificity and accuracy of PCa diagnosis, and decrease the false negative and false positive rates; the diagnostic efficiency of the combination of the two is superior.
