We herein reported a 27-year-old woman with a right renal mass for two years. She underwent laparoscopic partial nephrectomy. Immunohistochemical examination of the specimen confirmed the diagnosis of solitary fibrous tumor by revealing its positive staining for cluster of differentiation (CD)34, epithelial membrane antigen (EMA), B-cell lymphoma-2 (Bcl-2) and CD99 in the tumor cells. No adjuvant treatment was carried out. The patient was in good health without local recurrence or metastasis during 2 years of follow-up. Laparoscopic partial nephrectomy for renal solitary fibrous tumor is an alternative treatment to radical nephrectomy. It can provide a good outcome. However, further follow-up and more cases of renal solitary fibrous tumor treated with laparoscopic partial nephrectomy are necessary to compare the oncological outcome with radical nephrectomy.

Objective To analyze CMV DNA stability of 30 EDTA plasma samples in the order of magnitude between 300 and 100 000 copies/mL over a 21 day period. Methods Thirty plasma samples were grouped into three categories according to the CMV DNA loads , including low CMV DNA contents , intermediate CMV DNA loads and high CMV DNA loads. Ten milliliters of whole blood was freshly collected from each patient. Plasma samples without hemolysis were divided into 1-ml aliquots. One aliquot was processed immediately (Day 0) for baseline PCR assays. The remaining aliquots were then processed after one , two, three, seven, 14 or 21 day of storage at 4℃. Results There was no significant difference between the mean of the difference time point in viral loads following storage at 4 ℃ by paired-samples t test, including Day 1 compared to Day 0 (t = 1.654, P =0.109), Day 2 compared to Day 0 (t = 1.487, P = 0.148), Day 3 compared to Day 0 (t = 1.609, P = 0.118), Day 7 compared to Day 0 (t=0.831, P=0.413), Day 14 compared to Day 0 (t=1.721, P=0.096), and Day 21 compared to Day 0 (t=0.244, P=0.810). Conclusion The concentration of CMV DNA in all samples stored at 4 ℃ for 21 days did not differ significantly from the baseline viral load ,and it was not observed the trend in continued degradation in different time point (Day 1, 2, 3, 7 and 14).

Purpose:
Elevated plasma D-dimer level is a poor prognostic factor for many solid tumors. However, limited research has been conducted on D-dimer in children with neuroblastoma (NB), and its clinical significance remains unclear. The present study investigated the clinical and prognostic significance of D-dimer in pediatric NB patients.
Methods:
A retrospective analysis of all newly admitted NB patients was conducted from January 2014 to December 2020.Baseline clinicopathological features, preoperative laboratory parameters, and follow-up information were collected. Univariate and multivariate analyses were performed to determine the relationship between D-dimer level, clinical features, and the prognostic value.
Results:
Among 266 patients, the median value of D-dimer was 2.98 ng/mL, of which 132 patients showed elevated D-dimer levels before surgery (>2.98 ng/mL). Univariate analysis revealed that elevated D-dimer was significantly associated with age, hemoglobin, neutrophil-to-lymphocyte ratio, neuron-specific enolase, 24-hour vanillylmandelic acid, overall survival, and so on (P < 0.05). Patients with elevated D-dimer levels had shorter median overall survival time when compared with normal D-dimer levels (P = 0.01). The prognosis was better in patients with normal D-dimer levels when combined with lower age, ganglioneuroblastoma tumor type, lower stage on International Neuroblastoma Staging System, low-risk group, and without bone metastasis or bone marrow metastasis. The continuous increase of D-dimer level after treatment indicated tumor recurrence or progression.
Conclusion
A high D-dimer level is associated with low overall survival, and an elevated D-dimer level after treatment indicates tumor recurrence and progression. D-dimer can be used as one of the evaluation factors for NB treatment or prognosis.

OBJECTIVETo observe the regulatory effects of psoralen, oleanolic acid, and stilbene glucoside, three active components of psoralea fruit, glossy privet fruit and tuber fleeceflower root respectively, on Aβ25-35induced self-renewal and neuron-like differentiation of neural stem cells (NSCs).
METHODSEmbryonic NSCs werein vitro isolated and cultured from Kunming mice of 14-day pregnancy, and randomly divided into the control group, the Aβ25-35 group, the Aβ25-35 +psoralen group, the Aβ25-35 +oleanolic acid group, and the Aβ25-35 + stilbene glucoside group. The intervention concentration of Aβ25-35 was 25 µmol/L, and the intervention concentration of three active components of Chinese medicine was 10(-7)mol/L. The effect of three active components of Chinese medicine on the proliferation of NSCs was observed by counting method. The protein expression of Tubulin was observed by Western blot and immunofluorescence. The ratio of Tubulin+/DAPI was caculated. Results Compared with the control group, the sperical morphology of NSCs was destroyed in the Aβ25-35 group, the counting of NSCs, the expression of Tubulin protein, and the ratio of Tubulin /DAPI all decreased (P <0.01, P <0.05). Compared with the Aβ25-35 group, the counting of NSCs, the expression of Tubulin protein, and the ratio of Tubulin + /DAPI all increased in the three Chinese medicine treated groups (P <0. 01, P <0. 05).
CONCLUSIONS25 µmol/L Aβ25-35 could inhibit self-renewal and neuron-like differentiating of NSCs. But psoralen, oleanolic acid, and stilbene glucoside could promote self-renewal of NSCs and neuron-like differentiation.
