ABSTRACT

OBJECTIVES@#To investigate the clinical characteristics, treatment, and prognosis of children with perianal fistulizing Crohn's disease (pfCD).@*METHODS@#A retrospective analysis was conducted on the children, aged 6-17 years, who were diagnosed with Crohn's disease (CD) from April 2015 to April 2023. According to the presence or absence of perianal fistulizing lesions, they were divided into two groups: pfCD (n=60) and non-pfCD (n=82). The two groups were compared in terms of clinical characteristics, treatment, and prognosis.@*RESULTS@#The incidence of pfCD was 42.3% (60/142). The proportion of males in the pfCD group was higher than that in the non-pfCD group. Compared with the non-pfCD group, the pfCD group had a significantly higher proportion of children with involvement of the colon and small intestine or those with upper gastrointestinal lesions (P<0.05). Compared with the non-pfCD group, the pfCD group had a significantly higher rate of use of infliximab during both induction and maintenance treatment (P<0.05). In the pfCD group, the children with complex anal fistula accounted for 62% (37/60), among whom the children receiving non-cutting suspended line drainage accounted for 62% (23/37), which was significantly higher than the proportion among the children with simple anal fistula patients (4%, 1/23) (P<0.05). There were no significant differences between the two groups in mucosal healing rate and clinical remission rate at week 54 of treatment (P>0.05). The pfCD group achieved a fistula healing rate of 57% (34/60) at week 54, and the children with simple anal fistula had a significantly higher rate than those with complex anal fistula (P<0.05).@*CONCLUSIONS@#There is a high incidence rate of pfCD in children with CD, and among the children with pfCD, there is a high proportion of children with the use of biological agents. There is a high proportion of children receiving non-cutting suspended line drainage among the children with complex anal fistula. The occurrence of pfCD should be closely monitored during the follow-up in children with CD.

ABSTRACT

OBJECTIVE@#To explore the characteristics of ADC value changes in DWI of newly diagnosed symptomatic MM patients and its correlation with R-ISS stage.@*METHODS@#The data of 148 newly diagnosed symptomatic MM patients treated by whole-body DWI scan at The First Affiliated Hospital of Soochow University from June 2016 to June 2019 were selected and retrospectively analyzed and 30 cases of age-matched healthy people were selected as controls. The differences of ADC values between the patients in normal control group, DWI- group and DWI+ group were compared, and the relationship between ADC values and R-ISS stage in MM patients was compared.@*RESULTS@#The plasma cell percentage of the patients in DWI+ group was higher than those in DWI- group. ADC values of vertebra, sternum, rib, pectoral girdle, pelvic girdle of the patients in DWI+ group were significantly higher than those in DWI- group and normal control group. The ADC values of each part of the patients in DWI- group were higher than those in normal control group. ADC values of sternum, rib and pectoral girdle in the patients at R-ISS stage III were higher than those at R-ISS stage I and II, while, there was no statistical difference between R-ISS stage I and II groups. And there was no significant difference in ADC values of other bone parts such as vertebra and pelvic girdle in patients at R-ISS stage Ⅰ-Ⅲ.@*CONCLUSION@#DWI+ in MM patients is related to higher tumor invasion. The ADC values of the DWI+ group are higher than those of the DWI- group; the bone ADC values of the DWI- patients are still higher than the normal ones. And there is a certain relationship between ADC value and R-ISS stage.

ABSTRACT

OBJECTIVES@#To evaluate the effectiveness of induction therapy with exclusive enteral nutrition (EEN) in pediatric Crohn's disease (CD).@*METHODS@#A retrospective analysis was performed on the medical data of 62 children with CD who received EEN in Children's Hospital, Zhejiang University School of Medicine, from March 2013 to August 2021. The medical data included general information and height, weight, Pediatric Crohn's Disease Activity Index (PCDAI), Crohn's Disease Endoscopic Index of Severity, C-reactive protein, erythrocyte sedimentation rate, and serum albumin level before treatment and after 8 weeks of treatment. The changes in the above indicators were compared before and after treatment.@*RESULTS@#Among the 62 children with CD, there were 39 boys (63%) and 23 girls (37%), with a mean age of (11.9±3.0) years at diagnosis. Among the 55 children who completed EEN treatment for at least 8 weeks, 48 (87%) achieved clinical remission at week 8. PCDAI at week 8 was significantly lower than that before treatment (P<0.001). Except for 17 children with involvement of the small intestine alone and 3 children with involvement of the colon who did not receive colonoscopy reexamination, the remaining 35 children with involvement of the colon received colonoscopy reexamination after the 8-week EEN treatment. Of the 35 children, 29 (83%) achieved mucosal healing. As for the 48 children who achieved clinical remission at week 8, there were significant improvements in height-for-age Z-score and body mass index-for-age Z-score at week 8 (P<0.01). As for the 7 children who did not achieve clinical remission at week 8, there were no significant changes in height-for-age Z-score and body mass index-for-age Z-score at week 8 (P>0.05).@*CONCLUSIONS@#The 8-week EEN treatment has a good effect on clinical remission and mucosal healing in children with CD. For the children with CD achieving clinical remission, EEN can improve their height and body mass index.

ABSTRACT

Purpose@#This study aimed to investigate the potential systemic antitumor effects of stereotactic ablativeradiotherapy (SABR) and apatinib (a novel vascular endothelial growth factor receptor2 inhibitor) via reversing the immunosuppressive tumor microenvironment for lung carcinoma. @*Materials and Methods@#Lewis lung cancer cells were injected into C57BL/6 mice in the left hindlimb (primary tumor;irradiated) and in the right flank (secondary tumor; nonirradiated). When both tumors grewto the touchable size, mice were randomly divided into eight treatment groups. These groupsreceived normal saline or three distinct doses of apatinib (50 mg/kg, 150 mg/kg, and 200mg/kg) daily for 7 days, in combination with a single dose of 15 Gy radiotherapy or not tothe primary tumor. The further tumor growth/regression of mice were followed andobserved. @*Results@#For the single 15 Gy modality, tumor growth delay could only be observed at the primarytumor. When combining SABR and apatinib 200 mg/kg, significant retardation of both primaryand secondary tumor growth could be observed, indicated an abscopal effect wasinduced. Mechanism analysis suggested that programmed death-ligand 1 expressionincreased with SABR was counteract by additional apatinib therapy. Furthermore, whenapatinib was combined with SABR, the composition of immune cells could be changed.More importantly, this two-pronged approach evoked tumor antigen–specific immune responsesand the mice were resistant to another tumor rechallenge, finally, long-term survivalwas improved. @*Conclusion@#Our results suggested that the tumor microenvironment could be managed with apatinib,which was effective in eliciting an abscopal effect induced by SABR.

ABSTRACT

Cantharidin poisoning has been proven to cause multiple organ damage. Acute circulatory failure, acute renal failure, and multiple organ failure resulting from cantharidin poisoning are the main causes of death for patients with cantharidin poisoning. However, research on the damage of main target organs and mechanism of cantharidin poisoning is not clear. This paper reviews the latest toxicological and pathological research literatures at home and abroad related to cantharidin poisoning and comprehensively summarizes the latest research progress on the toxicological and pathological damage and mechanism of the digestive system, circulatory system, respiratory system, urinary system, reproductive system, skin mucosa, immune system, and nervous system after cantharidin poisoning, to provide reference for improving the molecular toxicological mechanism of cantharidin poisoning and decision-making in the clinical intervention of cantharidin poisoning.

ABSTRACT

Inflammatory bowel disease (IBD) is a chronic recurrent non-specific inflammatory disease in the intestinal tract. About 10%-56% of children with Crohn's disease and about 10% of children with ulcerative colitis have growth retardation. This study reports four adolescents with IBD and growth hormone deficiency who were diagnosed with Crohn's disease. There were three boys and one girl, with an age of 11.0-13.9 years and a disease duration of 11-85 months at diagnosis. The four patients had the involvement of the small intestine only, the colon only, both the small intestine and the upper gastrointestinal tract, and both the small intestine and the colon respectively. The pediatric Crohn's disease activity index ranged from 27.5 to 45 points. All four patients had a height-for-age Z-score (HAZ) of <-2, and the growth hormone provocative test suggested growth hormone deficiency. Of all four patients, two received recombinant human growth hormone combined with infliximab, one received infliximab only, and one received recombinant human growth hormone combined with mercaptopurine. All four patients had an improvement in HAZ after treatment.

ABSTRACT

PURPOSE: To explore the influence of S100 calcium binding protein A4 (S100A4) knockout (KO) on methionine-choline-deficient (MCD) diet-induced non-alcoholic fatty liver disease (NAFLD) in mice. MATERIALS AND METHODS: S100A4 KO mice (n=20) and their wild-type (WT) counterparts (n=20) were randomly divided into KO/MCD, Ko/methionine-choline-sufficient (MCS), WT/MCD, and WT/MCS groups. After 8 weeks of feeding, blood lipid and liver function-related indexes were measured. HE, Oil Red O, and Masson stainings were used to observe the changes of liver histopathology. Additionally, expressions of S100A4 and proinflammatory and profibrogenic cytokines were detected by qRT-PCR and Western blot, while hepatocyte apoptosis was revealed by TUNEL staining. RESULTS: Serum levels of aminotransferase, aspartate aminotransferase, triglyceride, and total cholesterol in mice were increased after 8-week MCD feeding, and hepatocytes performed varying balloon-like changes with increased inflammatory cell infiltration and collagen fibers; however, these effects were improved in mice of KO/MCD group. Meanwhile, total NAFLD activity scores and fibrosis were lower compared to WT+MCD group. Compared to WT/MCS group, S100A4 expression in liver tissue of WT/MCD group was enhanced. The expression of proinflammatory (TNF-α, IL-1β, IL-6) and profibrogenic cytokines (TGF-β1, COL1A1, α-SMA) in MCD-induced NAFLD mice were increased, as well as apoptotic index (AI). For MCD group, the expressions of proinflammatory and profibrogenic cytokines and AI in KO mice were lower than those of WT mice. CONCLUSION: S100A4 was detected to be upregulated in NAFLD, while S100A4 KO alleviated liver fibrosis and inflammation, in addition to inhibiting hepatocyte apoptosis.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical features and prognosis of gastrointestinal injury caused by foreign bodies in the upper gastrointestinal tract in children.</p><p><b>METHODS</b>A retrospective analysis was performed for the clinical data of 217 children who were diagnosed with foreign bodies in the upper gastrointestinal tract complicated by gastrointestinal injury by gastroscopy from January 2011 to December 2016, including clinical features, gastroscopic findings, complications, and prognosis.</p><p><b>RESULTS</b>Among the 217 children, 114 (52.5%) were aged 1-3 years. The most common foreign body was coin (99/217, 45.6%), followed by hard/sharp-edged food (45/217, 20.7%) and metal (35/217, 16.1%). The most common gastrointestinal mucosal injury was ulceration (43.8%), followed by erosion (33.2%). Compared with other foreign bodies, button cells were significantly more likely to cause esophageal perforation (P<0.01). The esophagus was the most commonly injured organ (207/217, 95.4%). Of all the 217 children, 24 (11.1%) experienced infection. The children with perforation caused by foreign bodies had a significantly higher incidence rate of infection than those with ulceration caused by foreign bodies (P=0.003). Of all the 217 children, 204 (94.0%) underwent successful endoscopic removal of foreign bodies. Among these children, 98 were hospitalized due to severe mucosal injury and were given anti-infective therapy, antacids, and supportive care including enteral nutrition through a nasogastric tube and/or parenteral nutrition. Of all the children, 10 left the hospital and were lost to follow-up, and all the other children were improved and discharged.</p><p><b>CONCLUSIONS</b>Most cases of foreign bodies in the upper gastrointestinal tract occur at 1-3 years of age. Coin, hard/sharp-edged food, and metal are the most common foreign bodies. Button cells are more likely to cause esophageal perforation. The incidence rate of secondary infection increases with the increasing severity of gastrointestinal mucosal injury. Children undergoing endoscopic removal of foreign bodies and enteral nutrition through a nasogastric tube tend to have a good prognosis.</p>

ABSTRACT

PURPOSE: This study aimed to identify potential epidermal growth factor receptor (EGFR) gene mutations in non-small cell lung cancer that went undetected by amplification refractory mutation system-Scorpion real-time PCR (ARMS-PCR). MATERIALS AND METHODS: A total of 200 specimens were obtained from the First Affiliated Hospital of Guangzhou Medical University from August 2014 to August 2015. In total, 100 ARMS-negative and 100 ARMS-positive specimens were evaluated for EGFR gene mutations by Sanger sequencing. The methodology and sensitivity of each method and the outcomes of EGFR-tyrosine kinase inhibitor (TKI) therapy were analyzed. RESULTS: Among the 100 ARMS-PCR-positive samples, 90 were positive by Sanger sequencing, while 10 cases were considered negative, because the mutation abundance was less than 10%. Among the 100 negative cases, three were positive for a rare EGFR mutation by Sanger sequencing. In the curative effect analysis of EGFR-TKIs, the progression-free survival (PFS) analysis based on ARMS and Sanger sequencing results showed no difference. However, the PFS of patients with a high abundance of EGFR mutation was 12.4 months [95% confidence interval (CI), 11.6−12.4 months], which was significantly higher than that of patients with a low abundance of mutations detected by Sanger sequencing (95% CI, 10.7−11.3 months) (p < 0.001). CONCLUSION: The ARMS method demonstrated higher sensitivity than Sanger sequencing, but was prone to missing mutations due to primer design. Sanger sequencing was able to detect rare EGFR mutations and deemed applicable for confirming EGFR status. A clinical trial evaluating the efficacy of EGFR-TKIs in patients with rare EGFR mutations is needed.

ABSTRACT

Objective To understand the association between pregnancy intention and pregnancy-related anxiety in the second and third trimester and its strength.Methods A prospective cohort study was conducted in Ma' anshan,Anhui province.A total of 3 474 eligible pregnant women within 14 weeks of gestation were recruited.The information about their demographic characteristics were collected in early pregnancy.The completed questionnaire of pregnancy-related anxiety were asked to return in the second and third trimester.Logistic regression analysis was conducted to evaluate the association between pregnancy intention and pregnancy-related anxiety in the second and third trimester.Results A total of 3 083 pregnant women were included in final analysis,The rate of unintentional pregnancy was 15.00% (n=461).The detection rates of pregnancy-related anxiety in the second and third trimester were 29.13% (n=898) and 30.36% (n=936).After controlling potential confounding factors,unintentional pregnancy increased the risk of pregnancy-related anxiety in the second trimester compared with intentional pregnancy (OR=1.85,95% CI:1.44-2.38);The risk of pregnancy-related anxiety also increased in the third trimester (OR=1.84,95% CI:1.44-2.35).Intentional pregnancy did not increase the risk of pregnancy-related anxiety in the second and third trimester.Conclusion The study results suggests that unintentional pregnancy could increase the risk of pregnancy-related anxiety in the second and third trimester.

ABSTRACT

In order to establish a real-time RT-PCR based on SYBR Green Ⅱ for detection of hepatitis E virus (HEV),a pair of special primers was designed according to the conserved sequences of ORF2 in GenBank.Result showed that the standard curve of established SYBR Green Ⅱ real-time RT-PCR had a wide dynamic range from 4.10 × 102-4.10 × 108 copies/μL with a linear correlation(r2) of 0.996.The sensitivity could reach 1.00 × 102 copies/μL.The melting curve analysis using SYBR Green Ⅱ dye showed one specific peak with a melting temperature(Tm) of 84.0 C ±0.1 C.No amplification was detected from the RNA samples of porcine reproductive and respiratory syndrome virus,classial swine fever virus,transmissible gastroenteritis virus,porcine bocavirus,porcine epidemic dearrhoea virus porcine kobuvirus and porcine rotavirus by this PCR,respectively.Excellent reproducibility was obtained for detecting constructed positive plasmid DNA with intra-assay of 0.83 %-0.94 % and inter-assay of 0.83%-0.94%.Further detection of 61 specimens showed that 9 of them were HEV positive,and the results of the quantitative RT-PCR were the same as that of the conventional RT-PCR.In conclusion,the real-time quantitative RT-PCR for HEV is feasible,the real-time RT-PCR established in this study will be useful for earlier rapid laboratory diagnosis and pathogenesis of HEV.
