This study investigated the changes of CD4(+) CD25(+) regulatory T cells (Tregs) in peripheral blood of patients with hepatocellular carcinoma before and after transcatheter arterial chemoembolization (TACE). The proportion of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in peripheral blood of 33 patients with hepatocellular carcinoma was determined by flow cytometry before, 1 week and 1 month after TACE. And 25 healthy volunteers served as control. One month after TACE, the patients were divided into two groups: 22 in group A, who were in stable condition or getting better; and 10 in group B, who were deteriorating. One patient died and was excluded. The results showed that the percentage of CD4(+)CD25(+) Tregs among CD4(+) T lymphocytes did not significantly change in the 33 patients 1 week after TACE as compared with that before TACE, however, the difference was significant (P<0.01) between the patients with hepatocellular carcinoma and the healthy subjects. The percentage of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in group A 1 month after TACE was decreased significantly in comparison with that before and 1 week after TACE (P<0.01), whereas, that in group B was increased significantly 1 month after TACE (P<0.01). It was concluded that patients with hepatocellular carcinoma had a higher proportion of CD4(+)CD25(+) Tregs in peripheral blood. TACE did not significantly affect the level of CD4(+) CD25(+) Tregs within short time (such as 1 week). The proportion of CD4(+)CD25(+) Tregs in peripheral blood 1 month after TACE was related to the prognosis of hepatocellular carcinoma.

Objective To develop a quantitative immunohistochemistry assay for duck hepatitis B virus core antigen (DHB-cAg)in duck liver tissue.Methods By comparison with no repair antigen and repair antigen with high pressure,microwave and trypsin,the best solution of antigen retrieval was determined.By optimizing the parameter of image acquisition and de-ducting blank area,mean density of yellow areas was calculated using Image-Pro Plus 6.0 software.Using the assay devel-oped to determine the level of DHBcAg in liver tissue from duck infected by DHBV,anti-DHBV activity of DHBcMAb-TAT PTD conj ugate was examined.Results SABC method with no repair antigen was selected,which was better than other methods.DHBcAg expression in duck liver tissue could be objectively and accurately quantified by setting Image-Pro Plus 6.0 software parameters and calculating mean density of yellow areas.By comparison with the differences between mean densityat baseline of treatment and end of treatment,it was showed that DHBcMAb-TATPTD conjugate treatment dose-de-pendently reduced the levels of DHBcAg in liver tissue,which show that the assay developed could effectively evaluate the anti-DHBV activity of agent.Conclusion The immunohistochemistry assay developed in this study can objectively and accu-rately evaluate the level of DHBcAg in duck liver tissue.

TCM proposes that the core pathological mechanism of depression is"deficient qi with stagnation and heat",with the following pathogenic characteristics and evolution patterns:"deficient qi"as the nature,and deficiency in nature is in spleen,and deficiency in superficiality is in brain;"stagnation"is the superficiality,and qi stagnation,phlegm stagnation,and blood stagnation are in the brain collaterals;"heat"fires the brain collaterals,depression raised the heat,and excessive heat accumulated to stagnation.Based on the understanding of the pathogenesis of depression caused by stress sensitization in modern medicine,this article explored the potential association between this mechanism and the core pathogenesis of"deficient qi with stagnation and heat".It proposed that tonifying deficiency,promoting circulation,and clearing heat are the basic treatment principles for depression.By inhibiting inflammatory reactions and improving the stress sensitization state of neurons and glial cells,TCM compound formulas can exert multi-target and multi-dimensional therapeutic characteristics.

This study investigated the changes of CD4+CD25+ regulatory T cells (Tregs) in peripheral blood of patients with hepatocellular carcinoma before and after transcatheter arterial chemoembolization (TACE). The proportion of CD4+CD25+ Tregs among CD4+ T lymphocytes in peripheral blood of 33 patients with hepatocellular carcinoma was determined by flow cytometry before, 1 week and 1 month after TACE. And 25 healthy volunteers served as control. One month after TACE, the patients were divided into two groups: 22 in group A, who were in stable condition or getting better;and 10 in group B, who were deteriorating. One patient died and was excluded. The results showed that the percentage of CD4+CD25+ Tregs among CD4+ T lymphocytes did not significantly change in the 33 patients 1 week after TACE as compared with that before TACE, however, the difference was significant (P<0.01) between the patients with hepatocellular carcinoma and the healthy subjects. The percentage of CD4+ CD25+ Tregs among CD4+ T lymphocytes in group A 1 month after TACE was decreased significantly in comparison with that before and I week after TACE (P<0.01), whereas,that in group B was increased significantly 1 month after TACE (P<0.01). It was concluded that patients with hepatocellular carcinoma had a higher proportion of CD4~CD25+ Tregs in peripheral blood.

The proportion of CD4+CD25+ Tregs in peripheral blood 1 month after TACE was related to the prognosis of hepatocellular carcinoma.

Objective: To investigate hepatitis C virus(HCV)genotyping and the serum HCV-RNA concentration in patients infected with different HCV genotypes and to provide information for evaluation of disease condition and anti-viral treatment efficacy. Methods: A total of 60 anti-HCV positive serum samples were collected before antiviral treatment. RT-PCR was performed for the 5′ non-cording region and was followed by nucleotide sequencing for HCV genotyping. Meanwhile, serum HCV-RNA concentration was detected by quantitative PCR. SPSS21.0 and Graphpad Prism 5.0 software were used for data analysis. Analysis of variance (ANOVA) was used for comparison among multi-groups and the t-test was used for comparison between two groups. Results: The frequencies of HCV genotypes 1b, 3a, 1a and 2a were 48.3% (29/60), 23.3% (14/60), 16.7% (10/60) and 10% (6/60), respectively. And, there is one subtype 2c was detected in this study. The mean serum viral concentration with standard deviation of HCV in genotype 1a, 1b, 2a, and 3 a were 5.46±1.19, 6.22±0.78, 5.47±0.65, and 5.38±0.98 log₁₀ (IU/ml) respectively. Conclusions The infection rate of HCV genotype 1 was significantly higher than that of genotype 2 and 3 (P<0.01). The statistical analysis showed the serum HCV-RNA concentration in patients with subtype 1b was significantly higher than that of the subtype group 1 a, 2 a, and 3 a (P<0.05). The study of the relationship between HCV genotypes and the serum HCV-RNA concentration may contribute to anti-viral treatment prescription for hepatitis C patients.

Objective:To investigate the association of peripheral axial lengths and retinal curvatures with refractive status.Methods:A cross-sectional study was conducted out.Two hundred and eighty-seven eyes of 287 consecutive children aged 6-15 years old who recieved eye examinations at Beijing Tongren Hospital from July to October 2021 were enrolled, including 154 males and 133 females.Uncorrected and best corrected visual acuity were tested with a standard logarithmic visual acuity chart.Spherical equivalent (SE) was measured via an auto refractometer after cycloplegia with tropicamide.The hyperopic, emmetropic and myopic groups were defined with a SE >+ 0.5 D, SE >-0.5 D to ≤+ 0.5 D and SE≤-0.5 D, respectively.Central and 30° peripheral eye lengths (nasal, temporal, superior, inferior) were obtained using the Lenstar LS900.Retinal coordinates were derived from partial coherence interferometry modeling and converted to retinal curvatures.According to the median horizontal peripheral eye length differences (absolute difference between nasal and temporal), participants were assigned to H1 group (absolute difference <0.35 mm) or H2 group (absolute difference ≥0.35 mm). According to the median vertical peripheral eye length differences (absolute difference between superior and inferior), participants were assigned to V1 group (absolute difference <0.32 mm) or V2 group (absolute difference ≥0.32 mm). Four groups of V1H1, V1H2, V2H1 and V2H2 were constructed according to the grouping methods in both directions above.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2021-162). Written informed consent was obtained from guardians of each subject prior to any medical examination.Results:The central axial length was 23.53(22.93, 24.10)mm.Peripheral eye lengths of temporal, nasal, superior and inferior were 22.75(22.11, 23.22)mm, 22.99(22.32, 23.45)mm, 23.24(22.58, 23.75)mm and 23.12(22.52, 23.56)mm, respectively.Temporal eye length was shorter than nasal, showing a statistically significant difference ( Z=-3.58, P<0.01). Compared with H2 group, H1 group had shorter central, nasal, superior and inferior eye lengths, showing statistically significant differences (all at P<0.05). Compared with V2 group, V1 group had shorter central, nasal and superior eye lengths, showing statistically significant differences (all at P<0.05). SE of H1 group was + 0.06 (-1.06, + 0.75) D, which was significantly greater than -0.32 (-1.64, + 0.56) D of H2 group ( Z=-2.10, P=0.04). SE of V1 group was + 0.13 (-0.81, + 0.80) D, which was significantly greater than -0.56 (-1.83, + 0.48) D of H2 group ( Z=-3.39, P<0.01). The myopia ratio of V1 group was 33.5% (58/173), which was significantly lower than 50.5% (53/105) of V2 group ( χ2=7.83, P<0.01). There was a significant overall difference in SE among VIH1, V1H2, V2H1 and V2H2 groups ( H=24.79, P<0.01). SE was greater in V1H1 group than V1H2, V2H1 and V2H2 groups (all at P<0.01). There was a significant difference in both horizontal and vertical retinal curvatures among different refractive groups ( H=22.34, 19.30; both at P<0.01). The retical curvature in both directions of hyperopic and emmetropic groups were significantly larger than those of myopic group (both at P<0.01). Conclusions:Peripheral eye lengths are asymmetric in school-aged children.Higher asymmetry is associated with myopic shifts.Myopic children have a steeper retina than the hyperopic and emmetropic children.

Objective:To explore the application value of four-dimensional automatic left ventricular quantitation(4D Auto LVQ) technology, in evaluating the myocardial mechanics in patients with different risk stratifications of hypertrophic cardiomyopathy(HCM).Methods:A total of 88 HCM patients and 20 healthy volunteers were selected from February 2020 to February 2022 in the First Affiliated Hospital of Zhengzhou University. According to the HCM Risk-SCD score, HCM patients were divided into 3 groups: low-risk group( n=49), intermediate-risk group( n=21), and high-risk group( n=18). Conventional ultrasound parameters were collected, and 4D Auto LVQ technology was used to obtain the mechanical parameters of left ventricular myocardium, including global longitudinal strain(GLS) , global circumferential strain(GCS), global area strain(GAS), global radial strain(GRS), twist and torsion. The differences in these parameters among the four groups were compared. The predictive values of conventional ultrasound parameters and myocardial mechanical parameters in patients with intermediate- and high-risk HCM patients were analyzed by ROC curve. Results:①Left ventricular end-diastolic diameter, left ventricular end-diastolic volume, left ventricular end-systolic volume, and peak systolic velocity of mitral annulus in the low-, intermediate-, and high-risk groups were lower than those in the control group while left ventricular maximal wall thickness(LVMWT) and early diastolic peak velocity of mitral value orifice/early diastolic peak velocity of mitral annulus(E/e′) were higher, left atrial diameter(LAD) and left ventricular outflow tract gradients(LVOTG) in the intermediate- and high-risk groups were higher than the low-risk group(all P<0.05). ②Compared with the control group, the GLS of HCM patients was lower, and the GLS of the intermediate- and high-risk groups was lower than the low-risk group. GCS and GRS in the intermediate- and high-risk groups were lower than those in the low-risk group. GAS in the high-risk group was lower than the low-risk and the control group, but higher than the intermediate-risk group(all P<0.05). Compared with the control group, the twist and torsion in the intermediate- and high-risk groups were higher, but lower than the low-risk group, and the differences were statistically significant(all P<0.05). ③The ROC results showed that the area under the curve(AUC) of the model containing conventional ultrasound parameters(LVWMT, LAD, and LVOTG) for predicting intermediate- and high-risk HCM patients was 0.811, with a sensitivity of 0.769 and a specificity of 0.755. The AUC of the conventional ultrasound parameters combined with myocardial mechanical parameters was 0.904, as the sensitivity was 0.667 and the specificity was 0.980. Conclusions:4D Auto LVQ can evaluate the mechanical characteristics of LV myocardium in HCM patients with different risk stratifications. Myocardial mechanical parameters combined with conventional ultrasound parameters can improve the diagnostic performance of patients with intermediate- and high-risk HCM.
