The most common type of intracranial malignancy is glioma. Although the current treatments are surgery, radiation and chemotherapy, the prognosis for patients with glioma is not promising. Therefore, it becomes critical to find an effective management. The literature shows that microRNA (miRNA) plays an important role in tumorigenesis and progression. Based on this, this study aimed to investigate the molecular mechanism of miR-525-5p in regulating the migration, invasion and proliferation of glioma cells. The TCGA database was used to identify perilipin 3 (PLIN3) differentially expressed in normal tissues and glioma tissues, and the CGGA and GEPIA databases were used to query that high expression of PLIN3 was associated with poor prognosis in glioma patients and Western blot experiments revealed that PLIN3 was highly expressed in glioma cells (P<0. 05) . The results of wound healing assay and Transwell invasion assay showed that knockdown or overexpression of PLIN3 respectively inhibited or promoted the migration and invasion of glioma cells (P < 0. 05) . Dual luciferase assays confirmed that PLIN3 could bind to miR-525-5p target. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) showed that miR-525-5p expression was lower in LN229 and U251 glioma cells than in human astrocyte (HA) (P < 0. 05) . Transwell assay and 5-ethynyl-2-deoxyuridine (EdU) cell proliferation assay verified that down- or up-regulation of miR-525-5p could reverse the effects of overexpression or knockdown of PLIN3 on LN229 glioma cells (P<0. 05) . Taken together, miR-525-5p was able to regulate the migration, invasion and proliferation of glioma cells by targeting PLIN3.

Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ²=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ²=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ²=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ²=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Objective:To evaluate the efficacy of basiliximab plus single steroid induced immunotherapy during donor-recipient ABO-compatible pediatric liver transplantation(LT).Methods:From January 1, 2019 to January 19, 2020, a total of 150 children of donor-recipient ABO-compatible LT were randomly divided into basiliximab group(basiliximab plus single steroid induction and postoperative immunosuppression with tacrolimus alone)and steroid group(conventional dose of steroid induction plus postoperative immunosuppression with tacrolimus and steroid). Clinical characteristics, survival rate of recipients and liver allografts, rejection rate and infection rate were observed.Results:The median follow-up time was 9.2(0.7~15.5)months.No significant inter-group differences existed in survival rate of recipients/grafts or the incidence of acute rejection, early postoperative pulmonary infection, cytomegalovirus and Epstein Barr virus infection. However, in 56 living donor LT, acute rejection(6cases, 10.7%)occurred in basiliximab group versus(12cases, 25.5%)in steroid group. During living donor LT, the incidence of acute rejection declined markedly in bsiliximab group as compared with steroid group( P=0.043). Conclusions:Both safe and effective for donor-recipient ABO-compatible pediatric LT, basiliximab plus single steroid induced immunotherapy can significantly lower the occurrences of acute rejection during living donor LT.

Accumulating evidence indicated that microRNAs (miRNA) play an important role in tumor invasion and metastasis by regulating their target genes.However, whether the miRNA-216b-5p(miR-216b-5p ) and their target genes butyrophilin subfamily 3 member A2(BTN3A2) promote glioma invasion and metastasis is unclear.This study aims to study whether miR-216b-5p promoted migration and invasion in glioma cells by negatively regulating BTN3A2.The differential expression analysis of GSE15824 and GSE4290 was analyzed by GEO2R.We found that only BTN3A2 is up-regulated in both GSE15824 and GSE4290 (P<0.05).The gene set enrichment analysis (GSEA) analysis indicated BTN3A2 was related to many cancer-related pathways (P<0.05).The results of survival curves showed that the overall survival of patients with high expression of BTN3A2 decreased significantly (P <0.001).The expression of BTN3A2 was increased with the increase of WHO grade (P<0.05), while the expression of BTN3A2 was increased in 1p/19q uncombined deletion and IDH mutant patients (P<0.001).Western blotting results showed that BTN3A2 was up-regulated in seven glioma tissues and glioma cell lines U87, U251 and LN-229 and downregulated in the miR-216b-5p mimics group; Transwell results showed that transfection with BTN3A2 silencing plasmids(si-BTN3A2) or miR-216b-5p mimics plasmids could inhibit the ability of migration and invasion in LN-229 cells in vitro (P<0.05).The online websites predicted miR-216b-5p as a potential target gene of BTN3A2.The survival curve results show that compared with patients with low expression of miR-216b-5p , the survival rate of patients with high expression was significantly increased (P=0.025).The relative expression of miR-216b-5p was decreased in U87, U251 and LN229 cells was detected by real time quantitative PCR (P<0.05).The results of dual luciferase assay showed that BTN3A2 could bind to miR-216b-5p (P<0.05).Transwell experiment results showed that overexpression of miR-216b-5p can inhibit the migration and invasion ability of LN229 cells (P<0.05).In summary, miR-216b-5p promotes the migration and invasion by targeting BTN3A2 of LN-229 glioma cells.

Objective To investigate the effect of microRNA (miR) - 140-3p targeting cell division cycle associated 8(CDCA8) on invasion and metastasis of lung adenocarcinoma cells. Methods The differentially expressed miRNAs were analyzed by GE02R in GEO database. The target genes of miR-140-3p were searched by TargetScan human7. 2 and miRWalk databases. The hub gene was screened by Cytoscape 3. 7. 2 software. GEPIA database was used to query the expression levels of target gene in lung adenocarcinoma tissues and normal lung tissues, the expression levels in different stages of lung adenocarcinoma, and the relationship between the expression levels of target gene and the overall survival rate of lung adenocarcinoma patients. The survival analysis of miR-140-3p in lung adenocarcinoma and the correlation between miR-140-3p and CDCA8 expression levels were searched in starBase database. Real-time PCR was used to detect the expression levels of miR-140-3p in normal lung epithelial cells BEAS-2B and lung adenocarcinoma cells A549, as well as the efficiency of infection. Expression levels of CDCA8 mRNA and protein were detected by Real-time PCR and Western blotting experiments after overexpression of miR-140-3p. Dual-luciferase reporter assay verified whether miR-140- 3p directly binds to CDCA8. Transwell invasion assay detected the effect of overexpression of miR-140-3p and CDCA8 on the invasiveness of lung adenocarcinoma cells. Results Analysis result from GEO and other databases showed that the expression level of miR-140-3p in normal lung tissues was significantly higher than that in lung adenocarcinoma, and its predicted target gene CDCA8 expression level in lung adenocarcinoma was significantly higher than that in normal lung tissues, and CDCA8 was negatively correlated with the expression level of miR-140-3p in lung adenocarcinoma. The experimental result showed that the expression of miR-140-3p in A549 cells was significantly lower than that in BEAS-2B cells (P<0.05). The expression level of miR-140-3p increased significantly after lentiviral infection (P<0.05). CDCA8 mRNA and protein expression levels were significantly down-regulated after overexpression of miR-140-3p (P<0.05). Dual-luciferase reporter assay result showed that miR-140-3p could directly bind to CDCA8 (P<0.05). Compared with the control group, overexpression of miR- 140-3p inhibited the invasion and metastasis of lung adenocarcinoma A549, while CDCA8 reversed the inhibition of miR-140-3p on the invasion and metastasis of lung adenocarcinoma A549 (P<0.05). Conclusion MiR-140-3p targeting CDCA8 inhibits the invasion and metastasis of lung adenocarcinoma cells.

AIM:To investigate the function of microRNA-125a-5p (miR-125a-5p) on epithelial-mesenchy-mal transition ( EMT) of breast cancer cells via GSK-3β/Snail signaling pathway. METHODS:The expression of miR-125a-5p in normal breast epithelial cells and breast cancer cells, as well as the transfection efficiency of miR-125a-5p plas-mid in MDA-MB-231 cells was detected by RT-qPCR. The chemotaxis ability and invasion ability were detected by chemo-taxis assay and Transwell invasion assay. The changes of EMT-related markers, the protein level of phosphorylated glycogen synthase kinase-3β (p-GSK-3β) and the nuclear translocation of Snail were determined by Western blot. RESULTS:The expression of miR-125a-5p in the breast cancer cells was significantly lower than that in the normal breast epithelial cells. The expression of miR-125a-5p was significantly higher in MDA-MB-231/miR-125a-5p cells than that in MDA-MB-231/NC cells. The ability of epithelial growth factor (EGF) at 10 μg/L to induce chemotaxis of MDA-MB-231 cells was the stron-gest. Compared with MDA-MB-231/NC group, stimulation of EGF decreased the invasion ability of MDA-MB-231/miR-125a-5p cells, and resulted in the increase in E-cadherin expression, while significantly decreased the protein levels of vi-mentin and p-GSK-3β. Meanwhile, the nuclear localization of Snail was significantly inhibited. The invasion capacity of MDA-MB-231/miR-125a-5p+GAB2 cells was significantly enhanced compared with MDA-MB-231/miR-125a-5p +Con cells, the expression of E-cadherin was decreased, and the protein levels of vimentin and p-GSK-3β were significantly in-creased, while the nuclear localization of Snail was promoted. CONCLUSION:miR-125a-5p suppresses EMT via GSK-3β/Snail signaling pathway, thus inhibiting the invasion ability of breast cancer cells.

OBJECTIVETo investigate the long-term outcomes of off-pump coronary artery bypass grafting (OPCAB) in patients aged over 75 years and analyze the risk factors affecting the outcomes of the procedure.

METHODSClinical data were reviewed for 97 consecutive patients aged 75 years or above receiving OPCAB at our center between November, 2000 and November, 2013. The perioperative data including length of ICU stay, duration of mechanical ventilation, incidence of postoperative complications and mortality rate of the patients were analyzed. The follow-up data of the patients were also analyzed including all-cause mortality rate and major adverse cardiac and cerebral events (MACCE, including myocardial infarction, cerebrovascular event, and repeated revascularization).

RESULTSThe perioperative mortality rate was 3.09% (3/97) in these patients. Of the 97 patients analyzed, 91 (93%) were available for follow-up for 29-192 months (with a median of 95.61∓34.07 months). The 10-year survival rate of the patients was 62% with a 10-year MACCE-free survival rate of 47.4%. During the follow-up, 6 (6.8%) patients underwent repeated revascularization procedures, 12 (12.37%) had cerebrovascular accidents and 5 (5.15%) had myocardial infarction. Logistic regression analysis showed that hypertension (OR=1.388, P=0.043) and diabetes (OR=1.692, P=0.017) were independent predictors of MACCE, and incomplete revascularization did not increase the risk of postoperative MACCE.

CONCLUSIONOPCAB is safe and effective in elderly patients with good long-term outcomes. Hypertension and diabetes are independent risk factors of MACCE, and adequate control of blood pressure and blood glucose can reduce the incidence of postoperative MACCE. Incomplete revascularization is not detrimental to the long-term outcomes of OPCAB in elderly patients.
