2.Research Progress in Noninvasive Early Diagnosis of Hepatocellular Carcinoma
Cancer Research on Prevention and Treatment 2023;50(1):75-80
Liver cancer is a common tumor that seriously threatens human life and health. Given that the early onset of liver cancer is insidious and lacks specific symptoms, hence it is difficult to screen through routine examination. Thus, clinical diagnosis of liver cancer is mostly in the advanced stage. However, advanced liver cancer has few treatment options, poor prognosis and high relapse rate, thereby causing a high mortality rate. Therefore, early diagnosis of liver cancer is particularly important. Currently, non-invasive screening of liver cancer widely used in clinical setups lacks sufficient sensitivity and specificity, hence, a more reliable diagnostic method needs to be found urgently. This article reviews the research progress of noninvasive early diagnosis of liver cancer to provide a reference for raising the early diagnosis rate of liver cancer.

Objective:To investigate the protein expression of GTPBP4 in human hepatocelluar carcinoma (HCC) tissues and the influ-ence of GTPBP4 silencing by siRNA on the proliferation and cell cycle of HCC cell line Hep G2. Methods:Western blot analysis was per-formed to observe the protein expression of GTPBP4 in 24 cases of HCC tissues compared with their adjacent noncancerous liver tis-sues. Lentivirus-mediated RNA interference (RNAi) was used to silence GTPBP4 expression in Hep G2, and the infection efficiency was observed under a fluorescence microscope. The silencing effect was tested by Western blot and real-time PCR. After silencing the GT-PBP4 gene, cell proliferation was detected using CCK-8 assay, and the cell cycle was observed using flow cytometry. Results:(1) GT-PBP4 was overexpressed in 21 cases (87.5%) of HCC tissues (P<0.000 1). (2) After the lentivirus with GFP reporter infected the Hep G2 cells, 90%of the cells showed green fluorescence. LV-GTPBP4-RNAi effectively inhibited the expression of GTPBP4 at both mRNA (70%) and protein (67%) levels. (3) The proliferation ability of the LV-GTPBP4-RNAi group significantly decreased after 96 h (inhibition rate:54.51%). Flow cytometry showed that the LV-GTPBP4-RNAi group significantly increased at the G0/G1 phase, whereas the S phase de-creased and arrested at the G0/G1 phase. Conclusion:GTPBP4 overexpression in HCC tissues was associated with hepatocarcinogenesis and promoted tumor cell proliferation, but the specific molecular mechanisms remain to be investigated.
4.Advances in the etiology and treatment of non-obese nonalcoholic fatty liver disease
Journal of Clinical Hepatology 2021;37(2):452-457
With the prevalence of nonalcoholic fatty liver disease (NAFLD) in the non-obese population, more and more studies have explored the significance of NAFLD in such population. Compared with the patients with obese NAFLD, the patients with non-obese NAFLD lack the phenotype of obesity, but they still have metabolic disorders and higher risk of metabolic and cardiovascular diseases. At present, there are no effective drugs for the treatment of non-obese NAFLD, and the existing treatment methods have their own advantages and limitations in clinical practice. This article reviews the advances in the etiology and treatment of non-obese NAFLD, in order to provide a reference for guiding the clinical treatment of non-obese NAFLD.

Objective To evaluate the effect of propofol postconditioning on necroptosis during hy-poxia-reoxygenation (H∕R) injury in diabetic cardiomyocytes. Methods Normally cultured H9C2 cardio-myocytes were divided into 5 groups (n= 19 each) using a random number table: control group (group C), high glucose group (group HG), H∕R group, propofol postconditioning (group P) and solvent dimethyl sulfoxide (DMSO) control group (group DMSO). H9C2 cells were incubated for 48 h in DMEM culture medium containing 5. 5 and 25 mmol∕L glucose in group C and group HG, respectively. In group H∕R, H9C2 cells were incubated for 48 h in DMEM culture medium containing 25 mmol∕L glucose and then un-derwent H∕R. H9C2 cells were incubated for 48 h in DMEM culture medium containing 25 mmol∕L glucose and then underwent H∕R, and propofol at the final concentration of 50 μmol∕L was added at the onset of reoxygenation in group P. In group DMSO, H9C2 cells were incubated for 48 h in DMEM culture medium containing 25 mmol∕L glucose and then underwent H∕R, and DMSO at the final concentration of 150μmol∕L was added at the onset of reoxygenation. The model of cardiomyocyte H∕R injury was established by subjecting cardiomyocytes to 6 h of hypoxia followed by 12 h of reoxygenation. At 12 h of reoxygenation, the cell viability was measured by CCK8 assay, the product of lactate dehydrogenase (LDH) in culture medium was measured, the level of reactive oxygen species (ROS) was determined by flow cytometry, cardiomyo-cyte apoptosis was detected by TUNEL, and the expression of receptor-interacting protein 1 ( RIP1), RIP3, Bax, Bcl-2, activated caspase-3 and caspase-3 was determined by Western blot. The apoptotic rate and ratio of activated caspase-3∕caspase-3 were calculated. Results Compared with group C, the cell via-bility was significantly decreased, the product of LDH was increased, the level of ROS and apoptotic rate were increased, the expression of RIP1, RIP3 and Bax was up-regulated, the expression of Bcl-2 was down-regulated, and the ratio of activated caspase-3∕caspase-3 was increased in group HG ( P < 0. 05). Compared with group HG, the cell viability was significantly decreased, the product of LDH was increased, the level of ROS and apoptotic rate were increased, the expression of RIP1, RIP3 and Bax was up-regula-ted, the expression of Bcl-2 was down-regulated, and the ratio of activated caspase-3∕caspase-3 was in-creased in group H∕R (P<0. 05). Compared with group H∕R, the cell viability was significantly increased, the product of LDH was decreased, the level of ROS and apoptotic rate were decreased, the expression of RIP1, RIP3 and Bax was down-regulated, the expression of Bcl-2 was up-regulated, and the ratio of acti-vated caspase-3∕caspase-3 was decreased in group P (P<0. 05), and no significant change was found in the indexes mentioned above in group DMSO (P>0. 05). Conclusion The mechanism by which propofol post-conditioning ameliorates H∕R injury in diabetic cardiomyocytes may be related to inhibiting necroptosis.

OBJECTIVETo investigate the association between ten single nucleotide polymorphisms (SNPs) in the peroxisome proliferator-activated receptors (PPARα, β, γ) with apolipoprotein A I/apolipoprotein B100 (ApoA I/ApoB100) ratio and the additional role of a gene-gene interactions among the 10 SNPs.
METHODSParticipants were recruited under the framework of the Prevention of Multiple Metabolic Disorders and Metabolic Syndrome in Jiangsu Province (PMMJS) cohort population survey in the urban community of Jiangsu province of China.A total of 630 subjects were randomly selected and no individual was related.Ten SNPs (rs135539, rs4253778, rs1800206, rs2016520, rs9794, rs10865710, rs1805192, rs709158, rs3856806 and rs4684847) were selected from the HapMap database,which covered PPARα, PPARβ and PPARγ. A linear regression model was used to analyze the relations between ten SNPs in the PPARs and ApoA I/ApoB100 ratio level. Mean difference and 95% CI were calculated. Interactions were explored by using the method of Generalized Multifactor Dimensionality Reduction (GMDR).
RESULTSAfter adjusting for age, gender, smoking status, alcohol consumption, occupational physical activity, high-fat diet as well as low-fiber diet, both rs1800206 and rs3856806 were significantly associated with a decreased level of ApoA I/ApoB100 ratio, mean difference (95% CI) values were -1.19 (-1.88 to -0.50) and -0.77 (-1.40 to -0.14). Whereas rs4253778 was significantly associated with an increased level of ApoA I/ApoB100 ratio, Mean difference (95% CI) values was 0.80 (0.08 to 1.52). GMDR analysis showed a significant gene-gene interaction among rs4253778, rs1800206 of PPARα, rs9794, rs2016520 of PPARβ and rs10865710, rs3856806, rs709158, rs1805192 of PPARγ for eight-dimension models (P = 0.01), in which prediction accuracy was 0.624 and cross-validation consistency was 7/10.
CONCLUSIONSThe rs1800206 of PPARα and rs3856806 of PPARγ are significantly associated with a decreased level of ApoA I/ApoB100 ratio while rs4253778 of PPARα is associated with an increased level of ApoA I/ApoB100 ratio. There is a gene-gene interaction between multiple SNPs.
