[Abstract] Objective: To explore the influence of miR-339-5p on the radio-sensitivity of lung cancer A549 cells by regulating the expression of Nudix hydrolase 5 (NUDT5). Methods: X-ray-resistant lung cancer A549 cells (RA549) were induced by treatment with low concentration gradient increment combined with large dose intermittent shock in vitro. The expression level of miR-339-5p in hu‐ man normal lung epithelial cells (BEAS-2B) and lung cancer cell lines (A549, L78, H1299, H460 and RA549 cells) was detected by qP‐ CR. According to the treatment, RA549 cells were divided into NC group, 5Gy group (treatment with 5Gy X-ray), 5Gy+miR-339-5p mimic group, 5Gy+si-NUDT5 group and 5Gy+si-NUDT5+miR-339-5p inhibitor group. CCK-8 assay, Annexin V-FITC/PI double stain‐ ing flow cytometry and WB were used to detect the proliferation, apoptosis and the protein expressions of NUDT5, γ-H2AX and H2AX in each group. The targeting relationship between mir-339-5p and NUDT5 was detected by Dual-luciferase reporter gene system. Results: The expression of miR-339-5p in lung cancer cell lines was significantly lower than that in BEAS-2B cells, with the lowest ex‐pression level in RA549 cells (all P<0.05). NUDT5 was the target gene of miR-339-5p. Compared with the NC group, the prolifera‐ tion activity and NUDT5 expression of RA549 cells in the 5 Gy group were significantly reduced (all P<0.01), and the apoptosis rate was significantly increased (P<0.01). Compared with the 5 Gy group, the proliferation activity of RA549 cells in the 5 Gy+miR-339-5p mimic group was significantly reduced (P<0.05), the apoptosis rate ([12.97±1.48]% vs [5.21±0.62]%, P<0.01) and the expression level of γ-H2AX (P<0.05) were significantly increased; the expression of NUDT5 (t=7.58, P<0.01) and cell proliferation activity (t=6.58, P<0.01) of RA549 cells in the 5 Gy+si-NUDT5 group were significantly reduced, while the apoptosis rate ([11.21±1.06]% vs [5.54±0.44%, P<0.01) and the expression of γ-H2AX (P<0.01) were significantly increased; and the above indicators in 5 Gy+si-NUDT5+miR-339-5p inhibitor group showed insignificant difference from the 5 Gy group. Conclusion: Overexpression of miR-339-5p enhances the radio-sensitivity of X-ray-resistant lung cancer A549 cells by targetedly down-regulating NUDT5 expression.

Objective:To study the related factors of pressure ulcer in liver transplantation patients, to understand the occurrence of postoperative pressure sores in liver transplantation patients, and to propose corresponding nursing strategies to provide theoretical basis for clinical nursing work.Methods:A total of 93 patients with liver transplantation were investigated for postoperative pressure ulcers using a general data sheet and a Braden risk assessment form.Results:The Braden risk score of liver transplantation patients was significantly positively correlated with pressure ulcers ( t value was -3.512, P<0.01). Among the risk factors affecting patients with surgical pressure sores, low pressure ulcer score, postoperative hypotension and low serum albumin were pressure ulcers. The risk factors, OR value were 1.185 (1.037-1.354), 9.443 (2.273-39.237), 1.325 (1.119-1.570), and the short operation time was the protective factor of pressure ulcer. The OR value was 0.729 (0.542-0.981). Conclusions:Clinical medical staff should take comprehensive measures to treat patients with liver transplantation in different situations, reduce the incidence of pressure ulcers and improve the quality of life of patients.

Objective To observe the effect of Sanqi Oral Liquid on the podocytes and the expression of slit diaphragm-associated molecules (including Nephrin, Podocin and CD2AP proteins) of diabetes mellitus (DM) rats after unilateral nephrectomy, so as to explore its mechanism for protecting renal function. Methods SD male rats were randomized into sham operation group, model group and Chinese medicine group. The experimental diabetes mellitus ( DM) model was given unilateral nephrectomy and intraperitoneal injection of 35 mg/kg of streptozocin (STZ). And then the model rats were given intragastric administration of Sanqi Oral Liquid (2.5 g· kg-1·d-1) and the same volume distilled water respectively for 8 weeks. After treatment, the density of podocytes and the podocytic foot process width of different groups were measured. Immunohistochemistry was used to observe the changes of the expression of Nephrin, Podocin and CD2AP in renal tissues of different groups. Results After treatment with Sanqi Oral Liquid, the density of podocytes was increased, the foot process lesion was relieved, and the expression levels of Nephrin, Podocin and CD2AP proteins were increased (P<0.05 or P<0.01 as compared with those in the model group). Conclusion The protective mechanism of Sanqi Oral Liquid for renal function of unilateral nephrectomy DM rats is possibly related with the alleviation of podocyte injury and with the regulation of the expression of Nephrin, Podocin and CD2AP proteins in podocytes.

OBJECTIVEThis study was to investigate the clinical and pathological characteristics, curative effect and prognosis of primary central nervous system lymphoma (PCNSL).

METHODSThe clinical and pathological features, diagnosis and treatment, curative efficacy and survival rate of 20 cases of primary central nervous system lymphoma were retrospectivaly analyzed.

RESULTSThe indicated that the clinical manifestations included headache, paralysis, seizures, dizziness and mental acuity, etc. There were 7 cases with single focus of lesion, 13 cases with multiple foci of lesions. The pathologic examimation showed 1 case of peripheral T-cell lymphoma and 19 cases of diffuse large B cell lymphoma, they all were from non-germinal center. Out of 20 cases, 11 cases with Ki-67>75%,6 cases with Ki-67 50%-75%, 2 cases with Ki-67 25%-50% and 1 case with Ki-67 10%. Therapeutic evaluation were as follows: 10 cases with CR, 2 cases with PR, 6 cases with PD in 18 patients recieved treatment. The use of ritusimab in treatment or no use and number of lesion foci in cranium were related to survival time (P < 0.05) . The survival time in group with Ki-67(+)<75% was longer than that in group with Ki-67(+)>75% (P = 0.042). Age and CSF-TP level were related to curative effect (P < 0.05) .

CONCLUTIONThere is no specific clinical manifestation. The physical examination and imageological diagnosis of PCNSL, as well as pathological biopsy are necessary for diagnose of PCNSL. The factors for poor prognosis include age > 60 years, CSF-TP > 600 mg/L, multiple lesions and Ki-67(+)>75%. PCNSL has high malignancy and poor prognosis. The chemotherapy based on high dose of MTX (among which MTX combined with rituximab) and HSCT after CR are the best treatment regimen for DLBCL.
