ABSTRACT

Objective To investigate the expression level of neutrophil extracellular traps (NET) in the peripheral blood and liver tissue of primary biliary cholangitis (PBC) patients and its correlation with clinical biochemical parameters. Methods A total of 24 PBC patients who were admitted to Renji Hospital, Shanghai Jiao Tong University School of Medicine, from August 2016 to August 2020 were enrolled, as well as 8 patients with primary sclerosing cholangitis (PSC) and 19 patients with autoimmune hepatitis (AIH) matched for age, and 19 healthy individuals were enrolled as healthy control group (HC group). The serum level of myeloperoxidase (MPO) was measured, and its correlation with clinical indices were analyzed. Immunofluorescence assay was used to measure the expression of NET in the liver of PBC patients, and an in vitro experiment was to compare the ability of peripheral blood neutrophils to produce NET between PBC patients and healthy controls. Normally distributed continuous data were expressed as mean±standard deviation, and the independent samples t -test was used for comparison between two groups; for the non-normally distributed continuous data expressed as M ( P 25 - P 75 ), the Kruskal-Wallis H test was used for comparison between multiple groups, and the Mann-Whitney U test was used for comparison between two groups. A correlation analysis was performed for MPO level and liver-related laboratory markers, and the Spearman's correlation coefficient was calculated. Results The serum level of MPO in the PBC group was increased to 811.21 (450.67-1 216.20) ng/mL, which was significantly higher than that in the AIH group [468.58 (142.63-812.43) ng/mL] and the HC group [357.54 (203.52-811.21) ng/mL] ( P < 0.05), suggesting that there was a significant increase in the production of NET in peripheral blood of PBC patients. The PSC patients had a serum MPO level of 763.56 (489.59-1 633.14) ng/mL, which was significantly higher than that in the HC group ( P < 0.05). MPO level was positively correlated with alkaline phosphatase ( r =0.500, P < 0.05), gamma-glutamyl transpeptidase ( r =0.426, P < 0.05), alanine aminotransferase ( r =0.521, P < 0.05), and aspartate aminotransferase ( r =0.547, P < 0.01). Confocal immunofluorescence showed colocalization of H3Cit and MPO in the liver of PBC patients. In vitro experiment showed that compared with the HC group, the PBC group had an increase in NET produced by peripheral blood neutrophils after in vitro stimulation and an increase in spontaneous production of NET. Conclusion There is an increase in NET in peripheral blood and liver of PBC patients, and the content of peripheral blood NET is positively correlated with biochemical parameters of liver function. NET may become a novel biomarker for assessing the severity of PBC.

ABSTRACT

OBJECTIVE: To research an appropriate estrogen therapy for in the pubertal development in Turner syndrome(TS)achievedbyestradiolvalerate.METHODS: In 57 TS girls of no spontaneous puberty or puberty arrest,we retrospectively studied pubertalstageanduterinedimensionduringtheestrogenreplacementtherapy.Datafrompatientrecordswascollected,described thepubertaldevelopingprocedure,and compared in groups which grouped by estrogen dosage to detect an appropriate dosage andthatcanleadabetterbreastanduterinedevelopment.RESULTS: The median age at start of puberty induction was 15.00 years,witharangeof11.5-21.0 years.(1)Breast development:Breast development to Tanner stage B2 was achieved in 0.29(0.25-0.33)years,stage B3 in 0.75(0.46,1.08)years,stage B4 in 2.20(0.92,3.08)years and B5 in 3.67(1.71,4.44)years.(2)Uterine development:The uterine volume and length in TS girls before treatment was 0.51(0.14,0.86)ml and 1.89(1.23,2.18)cm. We groupedthepatientsofTannerstageB2 ingroupsofestrogendosage≤0.5 mg/dand>0.5 mg/d and the uterine dimension and weightshowednodifference.Whenthepatientsweregroupedasgroupsofdosage<1.0 mg/d and group of dosage≥1.0 mg/d in stageB3,the uterine indexes in lower dosage group were less than group with larger dosage. When they were grouped as groups ofdosage<1.5 mg/d and ≥1.5 mg/d,the uterine volume 6.96(3.15-11.00)ml in lower dosage group was smaller than that in group withlargerdosage.CONCLUSION: During estrogen treatment in TS girls,normal breast development can be achieved. In a clinical setting,the uterine volume and length under pubertal induction developed properly with the breast stages progressing. when the breastdevelopedtostageB2,the uterine development was more dependable on estrogen. We recommend a low daily beginning estrogendosageuntilstageB2,which can be increased gradually after B2 to speed up the uterine development.

ABSTRACT

Objective@#To compare and analyze patient’s general condition, laboratory testing and therapeutic responses of isolated immunoglobulin G4- related sclerosing cholangitis (IgG4-SC) and immunoglobulin G4 sclerosing cholangitis combined autoimmune pancreatitis (IgG4-SC/AIP).@*Methods@#A retrospective study was conducted on IgG4-SC patients who attended outpatient and inpatients department of our hospital from April 2014 to March 2018 and their demographic characteristics, laboratory testing, and therapeutic responses were statistically analyzed. Normal distribution of continuous variables was compared with t-test, non-normal distribution of continuous variables was compared using the Mann-Whitney U test, and the categorical variables were compared with χ 2 test.@*Results@#29 IgG4-SC patients were included, including 19-isolated IgG4-SC and 10 IgG4-SC combined AIP (IgG4-SC/AIP). The average age of onset in the isolated IgG4-SC group was (46.06±19.03) years which was lower than IgG4-SC/AIP group (62.60±15.11), t = -2.360, P < 0.05. The median IgG4 in IgG4-SC/AIP patients is higher than that in isolated IgG4-SC, respectively 10.87 (3.73 ~ 20.13) and 3.14 (2.37 ~ 4.78)g/L(U = 159.000, P < 0.05). IgG4/IgG ratio is higher in IgG4-SC/AIP, than that in isolated IgG4-SC, respectively 0.62(0.23 ~ 0.86) and 0.16(0.10 ~ 0.21), U = 130.000, P < 0.05. Liver cirrhosis was more common in isolated IgG4-SC group (47%) than the IgG4-SC/AIP group (0), χ 2 = 9.637, P < 0.05. The median biochemical response time of isolated IgG4-SC group was 3.00 (2.00 to 4.00) months, which was longer than 1.00 (1.00 to 1.25) months of IgG4-SC/AIP group, U = 30.000, P < 0.05. The biochemical recurrence rate of isolated IgG4-SC group was 32%, which was lower than that of IgG4-SC/AIP (χ 2 = 6.461, P < 0.05).@*Conclusion@#Serum IgG4 level and IgG4/IgG ratio were higher in patients with IgG4-SC/AIP group, and therapeutic responses in isolated IgG4-SC patients were worse than that of IgG4-SC/AIP patients. The efficacy of glucocorticoid monotherapy and immunosuppressive agents combined with glucocorticoid therapy demonstrated no considerable difference in IgG4-SC patients.

ABSTRACT

Objective To explore the expression and significance of CXCL13 in gastric mucosa of children with nodular gastritis. Methods A total of 216 pediatric patients with clinically diagnosed gastritis under gastroscopy were randomly divided into nodular group and non-nodular group according to whether there were nodular changes under endoscopy. The pathological characteristics of gastric mucosa and the expression of CXCL13/CXCR5 in gastric mucosa of all patients were evaluated. Results The infection rates of Helicobacter pylori(HP)in gastric mucosa in nodule group(n=102)and non-nodular group(n=114)were 70.59% and 42.11%, respectively; the rate of severe mononuclear cell infiltration were 74.51% and 22.81%, respectively; the proportion of neutrophil infiltration were 62.75% and 33.33%, respectively; lymph follicles occurred in 64.71% and 20.18%, respectively; and there were statistical differences between the two groups (P<0.001). Positive staining of CXCL13 and CXCR5 were found in the gastric mucosa of all HP infected patients. The percentages of positive cells of CXCL13 and CXCR5 in the gastric mucosa of the nodules group were (71.33±7.14)% and (73.54 ± 7.92)%, which were higher than those in the non-nodule group (45.88 ± 5.92)% and (50.42 ± 5.98)%, respectively, and there were statistical differences (P<0.001). Conclusions Nodular gastritis in children is mainly associated with Hp infection. The expression of CXCL13/CXCR5 is increased in gastric mucosa in children with Hp infection, especially in nodular gastritis, it may be involved in the formation of lymphoid tissue in gastric mucosa.

ABSTRACT

Background:Activation of hepatic stellate cells( HSCs)plays a pivotal role in development of liver fibrosis. Interleukin-17(IL-17)is the most important effector of T helper 17(Th17)cells that causes inflammatory cell infiltration and tissue damage. Preliminary studies showed that the number of IL-17-positive cells in liver tissue was positively correlated with the severity of liver fibrosis in patients with chronic hepatitis B and autoimmune hepatitis. However,the mechanism of IL-17 in liver fibrosis is not yet clarified. Aims:To investigate the effect of IL-17 on activation of human HSC cell line LX2 and collagen expression. Methods:Human HSC cell line LX2 was treated with different concentrations of IL-17. Viability of LX2 cells was measured by CCK-8 assay. mRNA expressions of α-smooth muscle actin(α-SMA), type Ⅰ collagen(Col-Ⅰ)and Col-Ⅲ were determined by real-time PCR. Protein expressions of α-SMA、Col-Ⅰ and Col-Ⅲ were detected by immunofluorescence. Results: Viability of LX2 cells increased with the increase of IL-17 concentration,but no significant differences were seen between any two groups(P > 0. 05). mRNA expressions of α-SMA, Col-Ⅰ and Col-Ⅲ in IL-17 treatment group(100 ng/ mL)were significantly higher than those in blank control group(P <0. 05). With the increase of IL-17 concentration,protein expressions of α-SMA,Col-Ⅰ and Col-Ⅲ gradually increased. Conclusions:IL-17 can promote the activation of HSCs and expressions of Col-Ⅰ and Col-Ⅲ,thereby contributing to the development of liver fibrosis.

<p><b>OBJECTIVE</b>To evaluate the effect of combined use of stanazolol (ST) on the final adult height (FAH) in girls with idiopathic central precocious puberty (ICPP) and apparently decreased linear growth during gonadotropin-releasing hormone analog (GnRHa) therapy.</p><p><b>METHOD</b>Sixty-three girls with ICPP and decreased velocity of growth of height (HV<4 cm/yr) during GnRHa therapy were divided into 3 groups based on the following types of interventions:group 1 (n = 20), GnRHa+ST [25-30 µg/(kg·d) every 3-month followed by 3-month discontinuation], group 2 (n = 21), GnRHa+recombinant human growth hormone [rhGH, 1-1.1 U/(kg·w)], group 3 (n = 22), GnRHa alone.HV, the advancement of bone age (BA) for chronological age (CA) (ΔBA/ΔCA) and FAH were compared among groups.</p><p><b>RESULT</b>(1)Total duration of ST combination therapy was (12.22 ± 3.62) months, while total duration of combination of rhGH was (13.22 ± 6.80) months. (2)HV increased significantly in both group 1 [ (2.79 ± 0.60) cm/yr vs. (6.27 ± 1.98) cm/yr, P < 0.01] and in group 2 [(2.80 ± 0.50) cm/yr vs. (6.25 ± 1.98) cm/yr, P < 0.01] during combined therapy, but maintained at low levels in group 3 [(3.95 ± 1.10) cm/yr vs. (3.34 ± 0.95) cm/yr, P > 0.05].No significant differences of ΔBA/ΔCA were found among the three groups [0.25(0.11∼0.28), 0.22(0.15∼0.31),0.19(0.10∼0.32), P > 0.05]. (3)FAH was significantly higher than predicted adult height (PAH) before combined therapy, as well as higher than target height (THt) in both group 1 [(156.25 ± 2.90) cm vs. (150.78 ± 3.70) cm, P < 0.01, (156.25 ± 2.90) cm vs. (153.94 ± 2.62) cm, P < 0.01], and in group2 [ (157.33 ± 4.69) cm vs. (152.61 ± 3.92) cm, P < 0.01, (157.33 ± 4.69) cm vs. (154.39 ± 4.72) cm, P = 0.01].In group 3, FAH was similar to PAH [(153.88 ± 2.6) cm vs. (152.54 ± 5.86) cm, P > 0.05], and was less than THt [(153.88 ± 2.6) cm vs. (155.60 ± 4.52) cm, P = 0.02]. (4)In girls treated with ST, no hirsutism, clitorism or hoarse voice was recorded.No polycystic ovary syndrome was found by B-mode ultrasound.</p><p><b>CONCLUSION</b>Intermittent combined use of low dose ST therapy can increase HV and thus improve FAH in girls with ICPP and apparently decreased linear growth during GnRHa therapy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To identify potential mutation in a Chinese family featuring X-linked alpha thalassemia/mental retardation syndrome (ATR-X).</p><p><b>METHODS</b>Based on clinical symptoms and inheritance pattern, linkage analysis of X chromosome short tandem repeats (X-STR) loci was carried out to locate the candidate gene. Subsequently, sequences of exons and exon-intron boundaries of the candidate gene were amplified with polymerase chain reaction (PCR). Potential mutations were detected by direct DNA sequencing. All patients were also analyzed for the trait of thalassemia.</p><p><b>RESULTS</b>Linkage analysis indicated the candidate gene to be ATRX. Subsequently, a homozygous missense mutation c.736C>T (p.R246C) was found in exon 9 of ATRX in all of the 3 patients. And a heterozygous mutation c.736C>T (p.R246C) was also identified in the patient's mother and grandmother. Similar mutations were not detected in other members of the family. Alpha thalassemia was detected in the proband and another patient, whose genotypes were determined as -α(3.7)/αα and --(sea)/αα, respectively.</p><p><b>CONCLUSION</b>Missense mutation of c.736C>T in ATRX gene is a mutation hotspot, and p.R246C may disturb the function of ATRX-DNMT3-DNMT3L domain (ADD), which may be responsible for the disease in this family.</p>

ABSTRACT

Children aerophagia is a relatively rare functional gastrointestinal disease.Its main clinical manifestations are swallowing air,chronic bloating,belching and increased anal exhaust.Since lack of understanding of children aerophagia in pediatricians,it can be very easily missed or misdiagnosed in clinic.Understanding of the research status about children aerophagia means to pediatric clinical guidance.This review summarizes the causes,clinical manifestation,diagnosis and treatment of children aerophagia.
