ABSTRACT
MicroRNA(miRNA) affect various biological processes such as cell differentiation, proliferation, and apoptosis by inhibiting the translation of target genes after transcription and are widely involved in the regulation of immune and inflammatory responses in organisms. Autoimmune liver diseases are a group of chronic inflammatory diseases of the hepatobiliary system mediated by abnormal immunity, and abnormal immune inflammatory response of liver tissue with the involvement of miRNA is closely associated with the development and progression of autoimmune liver diseases. This article reviews the current research advances in miRNA in autoimmune liver diseases.
ABSTRACT
Objective To understand the epidemiological characteristics of the newly diagnosed pulmonary tuberculosis patients in Meishan City from 2014 to 2019, and to carry out trend prediction and analysis, so as to provide theoretical basis for the formulation of prevention and control strategies. Methods Raw data of newly diagnosed tuberculosis patients in Meishan City from 2014 to 2019 were collected from Meishan Statistical Yearbook. And Excel was used to manage the raw data. The epidemiological characteristics of newly diagnosed pulmonary tuberculosis patients in Meishan City from 2014 to 2019 were analyzed, and the epidemic trend of pulmonary tuberculosis in Meishan City in the next two years was predicted by grey GM(1,1) model. Results From 2014 to 2019, a total of 1 832 smear positive pulmonary tuberculosis cases were reported in Meishan City. The annual average reported incidence rate of smear positive pulmonary tuberculosis was 26.95/100 000. The overall incidence rate of smear positive pulmonary tuberculosis showed a downward trend. Among the 1 832 newly diagnosed tuberculosis cases, the majority were male, aged 31~40 years old, spring onset, township residence and rural residence, farmers and students. The predicted incidence of pulmonary tuberculosis in Meishan City from 2014 to 2019 based on grey GM(1,1) model is basically consistent with the actual incidence, and the predicted incidence of pulmonary tuberculosis in 2020 and 2021 are 27.68/100 000 and 30.25/100 000 respectively. Conclusion The incidence of newly diagnosed pulmonary tuberculosis in Meishan City from 2014 to 2019 has a downward trend in general, while it may increase in the next two years, so the prevention and control measures for high-risk groups, regions and seasons should be strengthened.
ABSTRACT
Objective@#To investigate the differential expression of serum-and-glucocorticoid-inducible-kinase-2 (SGK2) in hepatocellular carcinoma (HCC) and normal liver tissues and the related mechanism mediating signal transduction of GSK-3 β / β catenin in HCC cells.@*Methods@#Twenty pairs of matched HCC and normal tissues were collected and the situation of expression of SGK2 mRNA was detected by real-time fluorescence quantitative PCR. Western blot was used to detect the levels of SGK2 protein in human HCC cell lines (Huh-7, SMMC-7721) and normal human liver cell line (L02). SGK2 siRNA was used to transfect human HCC cell lines (SMMC-7721 and Huh-7), and then the protein expression levels of GSK-3 β/ β - catenin was successfully detected with the above-mentioned transfected cell line by western blot. Measurement data were expressed as mean ± standard deviation (±s), and the Student t -test was used as the statistical method.@*Results@#SGK2 mRNA expression was up-regulated in all 20 HCC samples than that of the expression of matched normal liver tissues. SGK2 protein levels were significantly higher in Huh-7 and SMMC-7721 than normal human liver cell lines (P < 0.01). The downregulation of SGK2 expression in human HCC cell lines (SMMC-7721 and Huh-7) had inhibited the expression of unphosphorylated GSK-3 β. In addition, the downregulation of SGK2 expression in HCC cell lines had decreased the dephosphorylation of β - catenin to prevent degradation of the β - catenin proteasome.@*Conclusion@#SGK2 is overexpressed in HCC and mediates GSK-3β/β- catenin signaling in HCC cells.
ABSTRACT
Objective@#To investigate the effect and mechanism of XTP4 gene in apoptotic hepatoblastoma HepG2 cell line.@*Methods@#HepG2 cells were transiently transfected with small interfering RNA of XTP4 genes, plasmid pcDNA3.1/myc-His(-) A-XTP4, and hepatitis B virus X protein transactivated x gene 4 (HBX protein trans-activate gene4, XTP4) and their respective negative controls. After 48h, the overexpression and interference expression condition of XTP4 in HepG2 cells were detected by Western blot. HepG2 cells apoptosis was detected by flow cytometry. The expression levels of apoptosis-related proteins P53, Bcl-2, Bax and Caspase-3 in HepG2 cells were detected by Western blot, and Bcl-2/Bax ratio was calculated. The chemiluminescence assay was used to detect activity of caspase-3 in HepG2 cells. The measured data were presented as ( ± s), and independent sample t-test was used for comparison between the two groups.@*Results@#HepG2 cells had successfully achieved the overexpression and interference expression of XTP4 protein. Compared with the control group, the overexpression of XTP4 in HepG2 cells had significantly decreased the number of apoptotic cells (P < 0.05), and increased Bcl-2/Bax (P < 0.05) ratio, but decreased the expression of P53 protein (P < 0.05). The protein expression of Caspase-3 and activity of caspase-3 was decreased (P < 0.05). However, interference with XTP4 expression in HepG2 cells had significantly increased the number of apoptotic cells (P < 0.05) and decreased Bcl-2/Bax (P < 0.05) ratio, but increased the expression of P53 protein (P < 0.05). The protein expression of Caspase-3 and activity of caspase-3 was increased (P<0.05).@*Conclusion@#In HepG2 apoptosis XTP4 has inhibitory effect, and its effect on inhibiting HepG2 apoptosis may be achieved by regulating the Bcl-2/Bax ratio, and the P53 protein may be involved.
ABSTRACT
Objective@#To investigate the change in expression of anti-senescence marker protein calmodulin (RGN) in liver tissues of rats with immune hepatic fibrosis, and to observe the effect of compound glutathione inosine injection (CGII) on it.@*Methods@#Rat liver fibrosis model was induced by intraperitoneal injection of porcine serum, and CGII intervention was administered at the appropriate time. Rat liver tissues were stained with HE and Masson. RGN and protein expression at mRNA in liver tissues was detected by fluorescence quantitative PCR and immunohistochemistry. One-way Anova was used for measurement data. LDS test was used for two-way comparison, and pathological semi-quantitative results were analyzed by rank-sum test.@*Results@#The relative expression of RGN mRNA and protein in liver tissue of fibrotic rats was 82.23 ± 15.21 and 12.52 ± 3.23, respectively, which were significantly lower than that of normal rats 176.39 ± 11.35 and 59.23 ± 9.13 (P < 0.01). The degree of liver fibrosis in fibrotic rats after CGII intervention was significantly lower than fibrotic rats. The relative expression of RGN mRNA and protein in the intervention group was 168.78 ± 21.31 and 46.42 ± 4.71, respectively, which were significantly higher than fibrosis and spontaneous recovery group. The difference was statistically significant (P < 0.01). The relative expression of RGN mRNA and protein in the spontaneous recovery group was 86.23 ± 17.16 and 14.34 ± 5.16, which was higher than model group. The difference was not statistically significant (P > 0.05).@*Conclusion@#The expression of RGN in liver tissue of rats with hepatic fibrosis induced by porcine serum is decreased, while the expression of RGN increases with the decrease of fibrosis after CGII intervention, suggesting that the protein may play an important role in the development of liver fibrosis.

Both groups were followed up for six months after discharge and then compared in terms of medication and diet compliance and re-bleeding rate. Result The patients in the experiment group were significantly better than those in the control group (P<0.05) in the medication and diet compliance. Conclusions The construction-process-result three-dimensional quality assessment mode can improve the quality of continuing nursing for the patients with liver cirrhosis after EVL. It can enhance the medication.
ABSTRACT
Because of development and popularization of the ultrasound techniques, the detection rate of nodal thyroid has increased. Surgery is the long-established therapeutic option. However, due to the surgical trauma, compli-cations and the effect on quality of life, various minimally invasive treatments have been proposed and widely used. A large number of foreign studies have shown that ultrasound-guided percutaneous ethanol injection is a more commonly used minimally invasive way to treat benign pure cystic and predominantly cystic thyroid nodules. This article provides an up-to-date review of the overseas studies and summarized on percutaneous ethanol injection for the treatment of benign cystic thyroid nodules.
ABSTRACT
ObjectiveTo explore the etiology and biochemical markers of acute liver failure (ALF) in children.Methods The cause and the biochemical markers of ALF in children who were treated in December 2014 to January 2011 were ana-lyzed retrospectively.ResultsA total of 67 children were enrolled, including 31 females and 36 males. According to the cause of the disease, the children were divided into non-genetic metabolic group, genetic metabolic group, and cryptogenic group. In the non-genetic metabolic group (29 cases, 43.28%) there were 12 cases of drug-induced ALF, 5 cases of Reye syndrome, 3 cases of hemophagocytic syndrome, 3 cases of herpes simplex virus infection, 2 cases of autoimmune hepatitis, one of case mushroom poisoning one case of hepatitis A virus infection, one case of cytomegalovirus infection and one case of sepsis respectively. In the genetic metabolic group (14 cases, 20.90%) there were 6 cases of Wilson’s disease, 2 case of glycogen storage disease, 2 of cas-es progressive familial intrahepatic cholestasis, 2 cases of neonatal intrahepatic cholestasis caused by citrin deifciency, one case of very long-chain acyl coenzyme A dehydrogenase deifciency and one case of primary carnitine deifciency. In the cryptogenic group there were 24 cases (35.82%). The serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, blood glucose level and AST/ALT were statistically signiifcantly different in genetic metabolic group from in non-genetic me-tabolism disease group and cryptogenic group, (P<0.05). The genetic metabolic group had the lowest levels of serum ALT, AST, albumin and glucose while the genetic metabolic group had the highest ratio of AST/ALT.ConclusionsThe etiology of ALF in children are complex. Genetic metabolic disease should be considered when the child with ALF has no signiifcantly elevated ALT, extremely high ratio of AST/ALT, combined with hypoproteinemia and hypoglycemia.
ABSTRACT
Objective To investigate the expressions of tumor suppressor gene FEZ1 and hypoxia inducible factor (HIF)-1α in oral squamous cell carcinoma (OSCC), and their correlation with clinicopathological features and prognosis. Methods A total of 146 specimens of OSCC and 80 normal oral mucosa were used to detect the expressions of FEZ1 and HIF-1αby immunohistochemistry. Thirty specimens of fresh OSCC tissues, 30 samples of the paracancerous tissues and 30 normal mucosa tissues were also included in the study. The relationship between the expressions of FEZ1 and HIF-1α, the clinicopathological features and the prognosis of the patients were analyzed. Western blot assay was used to detect the expres?sions of FEZ1 and HIF-1αin 30 fresh OSCC tissues, 30 samples of the paracancerous tissues and 30 normal mucosa tissues. Results In OSCC tissues, the positive rate of FEZ1 protein (30.14%) was significantly lower than that in normal oral muco?sa (81.25%), and the positive rate of HIF-1αprotein (71.23%) was significantly higher than that in normal mucosa (12.50%,χ2=54.076 and 71.317, P<0.01). There was a correlation between the expression of FEZ1 and clinical stage, tumor size and differentiation. The expression of HIF-1αwas correlated with gender, lymph node metastasis, tumor size and differentiation. There was no significant difference in 5-year survival rate between positive and negative FEZ1 expression groups. The 5-year survival rate was significantly lower in HIF-1α positive expression group than that of HIF-1α negative expression group (P<0.05). The expression level of FEZ1 was decreased by the sequences in normal oral mucosa, paracancerous tissue and OSCC (P<0.01), but the expression level of HIF-1αwas increased in turn (P<0.01). Conclusion FEZ1 and HIF-1αmay be involved in the occurrence and progress of OSCC. The expressions of FEZ1 and HIF-1αcan be used as a reference for the biological behavior of OSCC.
