ObjectiveTo establish an in vitro culture model of rat corpora cavernous smooth muscle cells (CCSMCs) using a modified tissue block adherence method. MethodsCorpus cavernosum smooth muscle tissue was digested with collagenase type I and subsequently cultured using an adherent method. Cells were purified via differential adhesion and identified through immunofluorescence and Western blotting. ResultsCCSMCs began to emerge from the tissue block after 3 days, increased significantly by day 7, and converged by day 12. Post-passage, CCSMCs exhibited strong proliferation and a “peak-to-valley” phenomenon. After purification, the cells tested positive for α-smooth muscle actin (α-SMA), confirming the successful establishment of the in vitro culture model. ConclusionThe modified tissue block adherence method is a cost-effective and efficient way to obtain high-purity CCSMCs.

Andrological diseases have become an important public health problem threatening men's health worldwide, which significantly affects the quality of life of patients and brings a heavy disease burden. Western medicine often faces the dilemma of obvious side effects and limited efficacy. Traditional Chinese medicine has unique advantages in the prevention and treatment of andrological diseases and has accumulated rich clinical experience. Epimedii Folium, as a traditional Chinese medicine for strengthening kidney and Yang, exerts a key therapeutic effect on andrology diseases through multi-component synergy, multi-target regulation, and multi-pathway intervention. Recent studies have found that the main active components of Epimedii Folium, such as icariin, icariside, and icaritin, are the key material basis for the treatment of andrological diseases. The active components of Epimedii Folium can play a role in common andrological diseases such as erectile dysfunction, male infertility, and prostate cancer by regulating the activity of the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) pathway, participating in oxidative stress response, regulating the secretion of hypothalamic-pituitary-gonadal axis hormones, improving spermatogenic dysfunction, and inhibiting the proliferation of cancer cells. However, the systematic action network and molecular mechanisms of the active components of Epimedii Folium have not been fully elucidated, thereby limiting its potential for clinical translation and application. In the future, it is necessary to combine cutting-edge technologies such as metabolomics, single-cell sequencing, and targeted nanoscale drug delivery systems, strengthening the research on the compatibility rules of active components and organ-specific delivery, providing a scientific basis for the development of innovative andrology traditional Chinese medicine formulas with international competitiveness, and promoting the innovation and breakthrough of andrology disease treatment modes.

Objective To investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on motor recovery in patients with incomplete spinal cord injury (SCI). Methods 22 patients with T5~T12 incomplete spinal cord injury (ASIA C) were randomly divided into rTMS group and control group. 12 ptients in rTMS group were treated with 10Hz rTMS (10×5 s with 2 min interval) on motor cortex and rehabilitation. 10 patients in control group treated with rehabilitation only. They were assessed with ASIA motor score, ASIA pin prick score, ASIA light touch score, range of motion (ROM) of legs in antigravitation position, walking index for spinal cord injury Ⅱ (WISCIⅡ) and functional independence measure (FIM) score before and 4 weeks after treatment. Results There was no difference between two groups with the clinical assessment before treatment (P>0.05). The ASIA motor score, ROM of legs and FIM score improved in both groups after treatment (P<0.05). The score of WISCIⅡ also improved in rTMS group (P<0.05), and ASIA motor score improved more in rTMS group than that of control group (P<0.05). Conclusion rTMS can facilitate the recovery of the motor and walking function in patient with incomplete spinal cord injury.

Objective To observe the effect of magnetic stimulation of sacral roots on detrusor overactivity and urge incontinence after spinal cord disease.Methods 15 cases with detrusor overactivity and urge incontinence after spinal cord disease were treated with magnetic stimulation of sacral roots for 10 d.Voiding diary,quality of life scale and urodynamic investigation were applied to evaluate the effect.Results The mean frequency of voiding in 24 h after treatment decreased,urine volume increased,frequency of incontinence decreased and the quality of life score improved.Urge incontinence improved in 85.7% cases.The results of urodynamic investigation showed bladder capacity at first desire to void and maximum cystometric capacity significantly increased after stimulation,while the detrusor pressure at storage decreased.Conclusion Magnetic stimulation of sacral roots can improve urinary frequency and urge incontinence of patients with detrusor overactivity after spinal cord disease by inhibiting detrusor overactivity,increasing cystometric capacity.Magnetic stimulation of sacral roots may be an alternative promising rehabilitation technique.
