Solitary fibrous tumors（SFT）is rare Mesenchymal tissue tumor，originally identified and usually found in the pleura，but the incidence of SFT in the spermatic cord is particularly rare.This article reported a case of a 37-year-old patient who was admitted for a right inguinal mass over the past 2 years. Preoperative MR examination showed a right spermatic cord-derived mass. Under spinal anesthesia，excision of the right spermatic cord mass was performed. Postoperative pathological diagnosis was spermatic cord solitary fibrous tumor. Twelve months of follow-up revealed no metastasis and recurrence on imaging examination. Solitary fibrous tumors of the spermatic cord are rare and require a combination of pathological examination and immunohistochemistry to confirm the diagnosis. Once the diagnosis is confirmed，tumor resection should be performed as soon as possible，and benign lesions are also at risk of recurrence，and long-term follow-up is required after surgery.

This article reports a case of a 55-year-old patient who was admitted to the hospital due to an 8-year history of a right epididymal mass and intermittent right scrotal heaviness for 1 month. Preoperative ultrasound examination revealed a right epididymal cyst and right testicular hydrocele. Under general anesthesia, a right epididymal mass resection and right testicular tunica vaginalis inversion procedure were performed. Postoperative pathological diagnosis was epididymal papillary cystadenoma. The patient has been followed up for 1 year with no recurrence and malignancy. Epididymal papillary cystadenoma, a rare benign tumor, lacks specific clinical and imaging features, often leading to misdiagnosis as seminal vesicle cysts or malignant tumors. If associated with von Hippel-Lindau syndrome, bilateral occurrence should be considered to prevent missed diagnosis and treatment delay.

Objective To study the amount of rhizospheric microorganisms and soil enzyme activity influenced by Paridis Rhizoma in different locations and of different strains. Methods The amount of rhizospheric microorganisms, soil enzyme activity and their correlation were researched through field survey and collection of rhizospheric soil in Paridis Rhizoma cultivated in Three Gorges Reservoir Region and by microbial dilution plate culture method. Results The amount of rhizospheric microorganisms in Paridis Rhizoma from different habitats showed significant differences. The dominant species in soil microflora was bacteria; the second one was actinomycetes; the fewest one was fungus. The variation trend of the amount of rhizospheric microorganisms was not consistent with the variation trend of rhizospheric microorganisms diversity index. The activity of soil phosphatase, invertase and pepsin in Paridis Rhizoma from different habitats varied. The correlation analysis showed that the correlation between the soil enzyme activity and the amount of rhizospheric microorganisms existed. Conclusion Choosing the suitable strains and habitats of Paridis Rhizoma is beneficial to enhancing the amount of rhizospheric microorganisms and soil enzyme activity, which can create good micro-ecological environment for growth and cultivation of Paridis Rhizoma.
