Abstract: Objective　To investigate the expression level and clinical significance of serum liver fibrosis-associated lncRNA1 (lnc-LFAR1) in patients with chronic hepatitis B cirrhosis, aiming to analyze its correlation with interleukin-6 (IL-6), interleukin-1β (IL-1β), and liver function. Methods　Patients with chronic hepatitis B (CHB) cirrhosis and CHB diagnosed and treated in Dongguan City People's Hospital from March 2016 to December 2019 were selected and divided into the liver cirrhosis group (n=80) and the CHB group (n=80), and 80 healthy people with physical examination during the same period were selected as healthy group. The serum levels of lnc-LFAR1, interleukin-6 (IL-6), albumin (ALB), interleukin-1β (IL-1β) and liver function indicators, including albumin (ALB) and alanine aminotransferase (ALT) were measured and analyzed. The correlation between serum lnc-LFAR1 expression level and IL-6, IL-1β was assessed, and the levels of lnc-LFAR1, IL-6, IL-1β, ALB and ALT were compared among patients with CHB cirrhosis of different Child-Pugh grades. Results The serum levels of lnc-LFAR1, IL-6, IL-1β and ALT in the patients with liver cirrhosis [(1.85± 0.62), (41.76±13.92) ng/mL, (7.78±1.95) pg/mL, (148.37±29.67) U/L] were higher than those in the CHB group [(1.42±0.47), (23.56± 7.85) ng/mL, (5.42±1.41) pg/mL, (87.59±17.52) U/L] and the healthy group [(1.01±0.34), (6.70±2.23) ng/mL, (3.13± 0.78) pg/mL, (15.44±3.10) U/L] (P<0.05), while the ALB levels (30.54±3.82) g/L were lower than those in the CHB group (37.27±4.34) g/L and the healthy group (45.26±5.66) g/L (P<0.05). Serum lnc-LFAR1, IL-6, IL-1β and ALT levels in the CHB group were higher than those in the healthy group (P<0.05), and ALB levels were lower than those in the healthy group (P<0.05); the serum levels of lnc-LFAR1, IL-6, IL-1β in patients with CHB cirrhosis were negatively correlated with ALB (P<0.05), and positively correlated with ALT (P<0.05); the serum expression level of lnc-LFAR1 in patients with CHB cirrhosis was positively correlated with IL-6 and IL-1β (r=0.598, 0.571, P<0.05); with the increase of Child-Pugh grade, the serum levels of lnc-LFAR1, IL-6, IL-1β, and ALT in patients with CHB cirrhosis gradually increased (P<0.05), and the level of ALB gradually decreased (P<0.05). Conclusions Serum lnc-LFAR1 expression level is higher in patients with CHB cirrhosis, which is obviously related to IL-6, IL-1β, ALB and ALT. Therefore, the evaluation of serum lnc-LFAR1 expression level is helpful in the clinical assessment of the condition of CHB cirrhosis patients.

Objective To investigate the relationship between recent chlamydia pneumoniae (Cp)infection and active ankylosing spondylitis (AS). Methods Seventy nine AS outpatients and 73 normal controls (NC) were enrolled into this study. Serum anti-Cp antibodies (CpIg) were tested using the enzymelinked immunosorbent assay (ELISA). Clinical and experimental data were collected. Patients with positive CpIgM or CpIgA were considered as having a recent Cp infection. Wilcoxon test, Student's t test, χ2 test and multivariate logistic regression were used for statistical analysis. Results Both AS patients and normal controls had a high prevalence for sero-positive CpIgG, which was 89％(70/79) vs 92％(67/73) respectively,while AS patients had a higher frequency of CpIgA and CpIgM when compared with NC [52％(41/79) vs 32％(23/73), χ2=6.61, P=0.010 for CpIgA; 80％(63/79) vs 21％(15/73), χ2=44.031, P＜0.01 for CpIgM]. The presence of CpIgM or CpIgA favored AS, the OR was 17.1 (95％CI 7.4～39.5), or 3.1 (95％CI 1.3～7.2),respectively. In addition, CpIgM was associated with disease activity parameters including ESR (χ2=2.56, P=0.021), CRP (χ2=7.28, P=0.007) and BASDAI (χ2=6.79, P=0.009). Furthermore, consecutive positive CpIgM favored the persistent active or relapsed disease, while negative CpIgM favored a reduced disease activity.There was no correlation between CpIgM/CpIgA and peripheral joint disease and enthesitis. Conclusion Recent Cp infection is highly associated with AS and CpIgM antibody relates with active AS, which indicates that Cp infections may be a critical triggering factor for active AS.

Objective To study the rhythmic changes of 24 h ambulatory blood pressure in pre-eclampsia(PE)patients and come up with coping strategies. Method The levels and circadian variations of blood pressures in 240 pre-eclampsia patients were monitored and observed with 24 h ambulatory blood pressure monitoring. Results Among the 240 PE cases,121 were diagnosed as mild PE and 119 as severe PE.There were significant differences in the average of 24 h circadian variation,the average of date time variation,decreased blood pressure at night time between the two groups(all P<0.05). Conclusion Through ambulatory blood pressure monitoring,nurses can monitor the rhythmic changes of 24 h ambulatory blood pressure,make reasonable arrangements for the treatment and care operations,reduce the factors that induce eclampsia and ensure the safety of mother and baby .

Objective To study the correlation between TCM differentiation of syndromes typing for ulcerative colitis (UC) and expressions of Bax and Caspase-3.Methods 50 patients with UC were divided into 2 groups according to TCM syndrome differentiation including dampness-heat internal accumulation syndrome group (25cases),deficiency of spleen and stomach syndrome group (25cases).Immunohistochemistry was used to study expression of Bax and Caspase-3 in colonic mucosas and compare with the normal group (25cases).Results The expressions of Bax were highest in dampness-heat internal accumulation syndrome group (4.56±1.58).The expressions of Bax of deficiency of spleen and stomach syndrome group were lower than dampness-heat internal accumulation syndrome group(3.28± 1.14)scores.There were significant differences between the three groups (P＜0.05).However,There were no significant difference between dampness-heat internal accumulation syndrome group and deficiency of spleen and stomach syndrome group in terms of the Caspase-3expressions (P＞0.05).In addition,Caspase-3 and Bax were positively related in each group(r=0.23and 0.21).Conclusion The high expressions of Bax,Caspase-3 in ulcerative colitis were closely related to TCM typing according to syndrome differentiation.Caspase-3 and Bax were adjustment in apoptosis.The detection of expression of Bax,Caspase-3 is helpful to the TCM syndrome differentiation and to the selection of treatment plan.At the same time,it can provide more important experiment basses for the pathogenesis of ulcerative colitis.

Objective To study the changes in the percentage of CD+4 CD+25 regulatory T (Tr) cells in peripheral blood and deciduas in unexplained recurrent spontaneous abortion (URSA) patients, normal non-pregnant and pregnant women respectively. Methods The percentage of CD+4 CD+25 Tr cells in deciduas and peripheral blood from 25 URSA patients, 22 normal non-pregnant (NNP) women, and 34 normal early pregnant (NP) women were measured by double-staining followed by flow cytometric analysis. Results (1) The percentage of CD+4 CDbright25 T cells in peripheral blood in both URSA and NP [ ( 1.55±0.77 ) %, (2. 65±1.10)%, respectively] women were increased significantly than that in NNP women [ (0. 39± 0.14)% P<0.05]. The percentage of CD+4 CDbright25 T cells in peripheral blood in URSA women was significantly lower than that in NP women (P<0.05 ). (2) The percentage of CD+4 CDbright25 T cells in decidua in URSA women was significantly lower than that in NP women [ ( 0. 59±0. 23 ) %, ( 1.24 ± 0. 55)%, respectively, P <0. 01 ]. There was no significant difference in the percentage of CD+4 CDdim25 T cells in decidua between URSA women and NP women [ (4. 23±1.52)%, (3.75±1.88)%, respectively, P>0.05]. (3) The proportion of CD+4 CDbright25/CD+4 cells in deeiduas was significantly higher than that in peripheral blood in NP women [(13. 10±10. 25 ) %, ( 5.59±2.62 ) %, respectively, P < 0. 05 ] . However, a significant difference in the proportion of CD+4 CDbright25/CD+4 between decidua and peripheral blood was not found in URSA patients [ (5. 16±2. 83 ) %, ( 4. 64±2. 07 ) %, respectively, P>0.05)].Conclusions The number of CD+4 CD+25 Tr cells is increased in normal pregnancy and decreased in URSA. Therefore, CD+4 CD+25 Tr cells may play an important role in maintaining maternal-fetal tolerance and may be involved in the pathogenesis of URSA.
