Journal of Sun Yat-sen University(Medical Sciences) 2020;41(6):825-833
Having been modified and improved in the past 40 years, transcatheter arterial chemoembolization (TACE) has now been widely accepted and recognized as the standard treatment for advanced hepatocellular carcinoma (HCC) by various clinical practice guidelines. In the era of precision medicine, although TACE has been faced with many new challenges, enhancing the effectiveness and security of TACE will be always our core mission. In accordance with the requirements of medical progress, interventionalists should be clear how to improve TACE technique and find more evidence to push the treatment forward.

Purpose:To study the diagnosis and treatment of ectopic opening of ureter with agenesis or ectopic kidney. Methods:8 cases of ectopic opening of ureter were reviewed.IVU, Ultrasonography, CT and MRU were used to make the preoperative diagnosis and open surgeries were followed. Results:Seven preoperative diagnoses were made by ultrasonography,three by IVU and five by CT. One patient with ectopic agenesis kidney failed to the above-mentioned methods except MRU.All diagnosis were confirmed by open surgery. Conclusions:The diagnosis value of IVP and CT in agenesis or ectopic kidney is questionable. Careful ultrasonography plays an important role in the diagnosis. MRU may be the most precise diagnostic method in localization that can clearly show ectopic opening of ureter with agenesis or ectopic kidney.

OBJECTIVETo study the effect of Xiangdan injection (XDI) in inducing adult SD rat marrow mesenchymal stem cells (rMSCs) orientedly differentiated into neuron-like cells, its characteristics and influencing factors were explored.
METHODSThe 5th generation of rMSCs cultured in vitro were pre-treated for 24 hrs by adding basic fibroblast growth factors (bFGF) into the medium, then the inducing liquid was replaced by XDI with different concentration to compare the rMSCs differentiation rate under different constitution of medium, different concentration of inducer and cell density of incubation. The induced cell survival rate under effects of above-mentioned factors was evaluated by trypan blue stain and MTT method.
RESULTSXDI in 1% - 5% concentration could induce rMSCs differentiated into neuron-like cells, the inducing rate reached 83.5 +/- 3.8% 6 - 12 hrs later, more than 90% cells, survival rate was over 36 hrs. The maximal inducing rate and cell survival rate could be obtained by treated with 3 % - 5% XDI, serum-free D/F12 + N2 + bFGF and with the cell density in 2.5 x 10(4)/cm2, when the other factors were the same.
CONCLUSIONXDI of 3% - 5% concentration, serum-free D/ F12 + N2 + bFGF (10 microg/L) and with the cell density incubated of 2.5 x 10(4)/cm2 is the optimal condition for oriented induction of rMSCs differentiating to neuron-like cells.

OBJECTIVETo study the relationship between the fibrinogen content in middle ear effusion (MEE) and the protracted inflammation of secretory otitis media (SOM) and to explore the possible mechanism of batroxobin in treatment of SOM.
METHODSThe fibrinogen content of middle ear effusion from 156 patients with SOM was investigated with concretion technique at different stages. After two times punctuation of tympanum, the recurrence patients were randomly divided into two groups: batroxobin and dexamethasone group, and 0.5 ml (2 BU/ml) batroxobin or dexamethasone (2 mg/ml) was injected into middle ear cavity. The therapeutic effects were investigated.
RESULTSThe concentration of fibrinogen in the recurrence group of SOM patients was higher than that in the cured group, and even higher in the second recurrence group than in the first recurrence group (P < 0.01). There was significantly different (P < 0.001) in the therapeutic efficacy between the batroxobin group (91.6%) and the dexamethasone group (62. 5%); the difference of the fibrinogen content in MEE and air conduction of pure tone audiometry at frequencies (0.5, 1.0, 2.0 kHz) between the two groups after treatment were also significant (P < 0.01).
CONCLUSIONSFibrinogen may play a significant role in the occurrence and development of secretory otitis media. Batroxobin had better therapeutic effect on SOM than dexamethasone. The mechanism of batroxobin in the treatment of SOM may be that the batroxobin can relief the depressant effect of fibrinogen on surface active agents of the Eustachian tube and prevent the fibrinogen from turning into insoluble fibrin polymer by means of fibrinolysis.

Objective:A retrospective study was conducted to evaluate the efficiency of postoperative radiotherapy for completely resected, pathologically Stage Ⅲ a (N2) non-small cell lung cancer (NSCLC). Methods:From January 1989 to December 1993, among the patients with NSCLC who underwent radical surgery in the authors’hospital, there were 119 patients with completely resected, pathologically Stage Ⅲ a(N2)NSCLC. A total of 55 cases of these patients received postoperative radiotherapy with dose of 46-62 gray in mediastinum and hilus (S+ RT group), except other 64 cases (S group). The survival rates and local control rates were analyzed and compared by the life table and Log-rank. Results:The clinical characters of patients such as age, sex, pathologic type were similar between two groups. The 1,3,5-year survival rates were 80.0% , 32.7% , 25.5% respectively in S+ RT group and 76.4% , 36.4% , 23.0% respectively in S group, with no significant difference between two groups( P >0.05) . The median time of local recurrence was 21 months in S+ RT group and 12 months in S group, with significant difference between two groups(P<0.05) . The 1,3,5-year local control rates were 94.0% , 78.5% , 69.0% respectively in S+ RT group in contrast to 83.1% , 58.3% , 50.6% respectively in S group(P< 0.05). The metastasis rates were similar in two groups ( P>0.05) . Conclusion:Postoperative radiotherapy can increase the local control rates and prolong the time of local recurrence for the patients with completely resected, pathologically Stage Ⅲ a (N2) NSCLC, but the survival rate can not be improved.

ObjectiveTo study the changes of miRNAs in exosomes secreted from microglia after being activated by exosomes of SH-SY5Y cells overexpressing α-synuclein (SNCA-HM Exo) and their effects on autophagy of SH-SY5Y cells. MethodsMicroglia exosomes were collected for miRNAs microarray analysis and PCR detection, and the differentially expressed miRNAs were screened out. Their target genes were analyzed by Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO). MiRNAs and their target genes related to PI3K/Akt/signaling pathway were screened out and verified by Western blot. The SH-SY5Y cells were divided into four groups:Con-HM Exo,Con-HM Exo+miR-19a mimic,SNCA-HM Exo and SNCA-HM Exo+miR-19a-3p inhibitor. ResultsFifteen differentially expressed miRNAs were screened out by microarray analysis and PCR. KEGG and GO analysis showed that PI3K/Akt signaling pathway had the highest enrichment score of target genes, and PTEN was one of the target genes regulated by mir-19a-3p. We found that, compared with the control group, the expression of PTEN and LC3 Ⅱ/I were decreased, while the expression of p-Akt/Akt, p-mTOR/mTOR and p62 were increased in the miR-19a-3p mimic group and the SNCA-HM Exo group (P < 0.05). However, miR-19a-3p inhibitor could reverse this effect (P < 0.05). ConclusionSNCA-HM Exo regulates PTEN through miR-19a-3p, activates PI3K/Akt/mTOR signaling pathway, and then inhibits autophagy in SH-SY5Y cells.

When hematopoietic stem cells (HSCs) were administrated by intravenous infusion (IV), most of them were trapped in some nonhematopoietic organs as like lungs that had abundant blood capillaries. Only a small fraction of injected cells could home to the bone marrow, which reduced the engraftment of HSCs. The purpose of intra-bone marrow (IBM) transplantation was to facilitate the homing of HSCs directly. Based on the established murine model for allogeneic umbilical cord blood transplantation (UCBT) by IBM injection, the objective of this study was to compare the distribution of fetal and neonatal peripheral blood (FNPB) mononuclear cells (MNC) in vivo and the efficacy of HSCT by different routes of administration in mice. BALB/c recipient mice exposed to sublethal dose 60Co gamma-ray were transplanted with FNPBMNCs from C57BL/6 mice. Recipient mice were divided into six groups at random: unilateral-IBM group; bilateral-IBM group; IV group; bilateral-IBM + IV group; irradiated control group and normal group. The distribution of CFSE-labeled FNPBMNCs in the recipients was observed in frozen sections of different organs or by flow cytometry. The survival rate, engraftment level, recovery of hematopoietic function and GVHD of recipient mice were studied. The results showed that infused by IBM route, FNPBMNCs mainly accumulated in the bone marrow (BM) cavity of the injected side tibia. Some of them could enter the BM of noninjected bones via blood circulation and few were trapped in the lung. Though same amount of FNPBMNCs were injected into recipient mice of unilateral and bilateral-IBM group, less cells could leak into peripheral blood or other tissues when transplanted by bilateral-IBM route. Therefore, in term of accelerating hemopoietic recovery, the injection of IBM route was better than IV route, especially bilateral IBM injection of HSCs, which neared the normal level of peripheral blood cells and colony-forming units of bone marrow nucleated cells at day 21 after transplantation, followed by unilateral-IBM group and bilateral-IBM + IV group. The percentages of H-2Db cell subsets in the three IBM groups were much higher than that in IV group. There was no significant difference of the engraftment level in the injected side tibia between the unilateral and bilateral-IBM group. When secondary transplantation was performed, the engraftment level in bilateral-IBM group was still much higher than that in IV group. At day 90, the survival rates of IBM groups were all > or = 80%, while that of IV group was only 50%. It is concluded that bilateral-IBM route can facilitate the homing of more HSCs, accelerate the engraftment of HSCs and hematopoietic reconstitution, which promoted the efficacy of IBM-HSCT.
