Purpose To investigate the relationship and clinical significance of high-risk human papillomavirus infection and expression of c-jun and c-fos protein in cervical carcinoma.Methods Cervista HR-HPV testing,immunohistochemical SP method were employed to detect the infection of HR-HPV,c-jun and c-fos protein in 70 cases of CSCC,60 cases of cervical intraepithelial neoplasia and 20 cases of chronic cervicitis.The correlation between c-jun and c-fos protein expression and of HR-HPV infection was analyzed.Results Of the 70 cases of CSCC,the positive HR-HPV was 69 cases,the positive rate in HR-HPV in A9 group was the highest (85％,59/69).The positive expression of c-jun and c-fos were 80％ (56/70),85.7％ (60/70) in 70 cases CSCC,70％ (21/30) and 70％ (21/30) in 30 cases of cervical high grade intraepithelial neoplasia,and 20％ (6/30),23.3％ (7/30) in 30 cases cervical low grade intraepithelial neoplasia,but the positive expression rates of c-jun and c-fos in the 20 cases of chronic cervicitis were 0.Expression of c-jun and c-fos in cervical cancer group was higher than that in the chronic cervicitis group and low grade intraepithelial neoplasia (P ＜ 0.05).The expression of c-jun and c-fos was statistically significant in different groups of clinical stage and pathologic grading in the CSCC (P ＜ 0.05).Additionally,the expression of c-jun and c-fos was positively correlated with the infection of HR-HPV in CSCC (P ＜ 0.01).Conclusion The infection of HR-HPV has significant subtype-specific and has a positive correlation with the expression of c-jun and c-fos in CSCC,which suggests that AP-1 pathway activation after HRHPV infection may be associated with the occurrence and development of cervical carcinoma.

Objective:To investigate the effects of berberine on Sprague Dawley (SD) rat retinal Müller cells cultured by high concentration glucose.Methods:The cultured SD rat retinal Müller cells were divided into normal-glucose group, high-glucose group, high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group, and the cells were cultured in 5 mmol/L glucose, 25 mmol/L glucose, 25 mmol/L glucose+ 10 μmol/L berberine, and 25 mmol/L glucose+ 25 μmol/L berberine, respectively.After 72 hours cultured, cell apoptosis rate was detected by flow cytometry; the expressions levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the culture supernatant were detected by enzyme linked immunosorbent assay (ELISA); the L-glutamate-L-aspartate transporter (GLAST) and the related protein expression levels were detected by real-time fluorescence quantitative PCR; the expressions levels of GLAST, protein phosphatase magnesium-dependent 1A (PPM1A), nuclear factor-κB (NF-κB) and cleaved caspase-3 in the cytoplasm, and the expression level of NF-κB protein in the nucleus were detected by Western blot.Results:The cell apoptosis rate was (1.37±0.21)%, (17.67±1.17)%, (10.60±0.17)% and (5.57±0.35)% in the normal-glucose group, high-glucose group, high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group, respectively, and the overall comparative difference was statistically significant ( F=375.97, P<0.01). The cell apoptosis rates in the high-glucose group was increased in comparison with those in the normal-glucose group ( P<0.01). The cell apoptosis rates in the high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group were significantly reduced in comparison with that in the high-glucose group (both at P<0.01). And the cell apoptosis rate in the high-glucose+ 25 μmol/L berberine group was lower than that in the high-glucose+ 10 μmol/L berberine group ( P<0.01). ELISA results revealed that the overall comparative differences of the concentrations of TNF-α, IL-8 and COX-2 among the four groups were statistically significant ( F=28.36, 35.88, 41.59; all at P<0.01). The concentrations of TNF-α, IL-8 and COX-2 in the high-glucose group were significantly higher than those in the normal-glucose group ( P<0.01). Compared with the high-glucose group, the concentrations of TNF-α and COX-2 were significantly decreased in the high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group (both at P<0.05). The concentrations of TNF-α and IL-8 in the high-glucose+ 25 μmol/L berberine group were lower than those in the high-glucose+ 10 μmol/L berberine group (both at P<0.05). Real-time fluorescence quantitative PCR showed that the relative expression levels of GLAST mRNA in Müller cells among the four groups were statistically significant ( F=268.60, P<0.01). Compared with the normal-glucose group, the relative expression level of GLAST mRNA was significantly decreased in the high-glucose group ( P<0.01). In the high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group, the relative expression level of GLAST mRNA was significantly elevated compared with the high-glucose group (both at P<0.05). Western blot analysis results showed that the overall comparative differences of the GLAST, PPM1A, cleaved caspase-3, NF-κB in cytoplasm and NF-κB in nucleus among the four groups were statistically significant ( F=135.20, 156.98, 80.96, 128.07, 47.36; all at P<0.01). The relative expression levels of GLAST, PPM1A and NF-κB protein in cytoplasm in the high-glucose group were significantly lower than those in the normal-glucose group, high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group (all at P<0.05). The relative expression levels of cleaved caspase-3 and NF-κB protein in nucleus in the high-glucose group were significantly higher than those in the normal-glucose group, high-glucose+ 10 μmol/L berberine group and high-glucose+ 25 μmol/L berberine group (all at P<0.05). Conclusions:High-concentration glucose can induce cell apoptosis and inflammatory response of SD rats retinal Müller cells in vitro.However, berberine can inhibit cell apoptosis and inflammatory response induced by high-concentration glucose via suppressing NF-κB translocation and transcription activity, and thereby inhibiting the expression of inflammatory cytokines.

Objective:To evaluate the feasibility of using two-dimensional shear wave elastography (2D-SWE) based liver and spleen elastic hardness (L/S-SWE) in patients with liver cirrhosis, and to determine the exclusion and diagnostic thresholds for early identification of liver cirrhosis.Methods:A total of 574 patients with chronic hepatitis B (hepatitis B for short) were included in this study. The clinical characteristics, L-SWE and S-SWE of the patients were collected, and the differences between cirrhosis group ( n=311) and non cirrhosis group ( n=263) were analyzed. The success rate and stability of liver and spleen elastic surgery were evaluated in two groups. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of L-SWE, S-SWE, aspartate aminotransferase to platelet ratio index (APRI) alone and in combination in diagnosing liver cirrhosis. By analyzing the ROC curve, the double threshold for excluding and diagnosing liver cirrhosis was determined. Results:There was a statistically significant difference in platelet count and APRI between the cirrhosis group and the non cirrhosis group (all P<0.05). In the feasibility assessment of 2D-SWE technology, the success rate and stability of liver and spleen elastic operation were relatively high (success rate: 97.2% vs 81.3%; stability: 0.92 vs 0.84), and the success rate and stability of L-SWE operation were slightly better than S-SWE. The success rate of S-SWE operation in the cirrhosis group was higher than that in the non cirrhosis group ( P<0.05). The correlation analysis results showed that L-SWE, S-SWE, APRI were positively correlated with liver tissue pathological grading ( r=0.677, 0.528, 0.149, all P<0.05). The areas under the ROC curve for identifying liver cirrhosis using L-SWE, S-SWE, and APRI were 0.959, 0.896, and 0.706, respectively. When L-SWE and S-SWE were combined, the area under the ROC curve was 0.987, the sensitivity was 92.6%, and the specificity was 96.0%. The Delong test showed that the combined diagnosis of L-SWE and S-SWE had the same diagnostic efficacy as using L-SWE alone for liver cirrhosis ( P>0.05). Further analysis of the ROC curve showed that the likelihood of liver cirrhosis was low when L-SWE was less than 9.4 kPa, and high when L-SWE was greater than 12.0 kPa. Patients between 9.4 and 12.0 kPa can undergo further S-SWE testing; If the S-SWE was between 17.5 and 29.3 kPa, it was classified as 2D-SWE, which was difficult to determine whether there was liver cirrhosis, and further liver puncture and other examinations were needed. Conclusions:2D-SWE technology has high operational feasibility in the diagnosis of liver cirrhosis, and combined with S-SWE, it helps to improve the diagnostic efficiency of early non-invasive identification of liver cirrhosis, enabling more patients to avoid unnecessary liver puncture examinations.

Objective To observe the changes in the subfoveal choroidal thickness(SFCT)of children and adoles-cents with different refractive states using optical coherence tomography angiography.Methods A total of 171 children and adolescents were followed.They were divided into the lower primary school group(6-8 years old),upper primary school group(9-11 years old),and junior high school group(12-14 years old)according to their age at the time of en-rollment.Dioptric examinations(including best corrected visual acuity,diopter,intraocular pressure,corneal curvature,axial length and SFCT)were performed,data collection was conducted twice in half a year(initial examination and review after half a year),and the eyeball parameters and changes in eyeball parameters after half a year among all groups were compared.Results The axial length and SFCT of subjects had significant differences among all groups(both P＜0.05).In children and adolescents,the axial length gradually lengthened and SFCT gradually thickened with age,while intraocular pressure and corneal curvature were not associated with age(both P＞0.05).In the initial examination and review after half a year,there was no significant difference in intraocular pressure,corneal curvature and SFCT of subjects with differ-ent refractive states in all groups(all P＞0.05),while the axial length of myopic subjects was greater than that of non-my-opic subjects in all groups(all P＜0.05).In the review after half a year,the SFCT of non-myopic subjects in the lower pri-mary school group and upper primary school group was significantly thickened(P＜0.001,P=0.003),while there was no significant difference in SFCT of myopic subjects in all groups compared with the value half a year ago(all P＞0.05).The axial length of all subjects showed a positive correlation with the SFCT in the initial examination and review after half a year(r=0.354,0.228,P＜0.05).Conclusion Myopia affects the increase in SFCT in children and adolescents.

Along with the develoipment of high-throughput sequencing technologies, both sample size and SNP number are increasing rapidly in genome-wide association studies (GWAS), and the associated computation is more challenging than ever. Here, we present a memory-efficient, visualization-enhanced, and parallel-accelerated R package called"rMVP"to address the need for improved GWAS computation. rMVP can 1) effectively process large GWAS data, 2) rapidly evaluate population structure, 3) efficiently estimate variance components by Efficient Mixed-Model Association eX-pedited (EMMAX), Factored Spectrally Transformed Linear Mixed Models (FaST-LMM), and Haseman-Elston (HE) regression algorithms, 4) implement parallel-accelerated association tests of markers using general linear model (GLM), mixed linear model (MLM), and fixed and random model circulating probability unification (FarmCPU) methods, 5) compute fast with a globally efficient design in the GWAS processes, and 6) generate various visualizations of GWAS-related information. Accelerated by block matrix multiplication strategy and multiple threads, the association test methods embedded in rMVP are significantly faster than PLINK, GEMMA, and FarmCPU_pkg. rMVP is freely available at https://github.com/xiaolei-lab/rMVP.
