ABSTRACT

Lung cancer is the malignant tumor with the highest mortality rate in the world. Radiotherapy plays an important role in the comprehensive treatment of lung cancer. With the continuous advancement of radiotherapy technology and equipment, it has become one of the effective therapeutic options for lung cancer. In recent years, artificial intelligence technology has developed rapidly and has been widely applied in clinical practice, especially in the diagnosis and treatment of lung cancer imaging. The image database can be obtained by sorting and summarizing the images, which can be used in clinical work and scientific research. In this article, the application of artificial intelligence in lung cancer radiotherapy imaging and lung cancer imaging database was reviewed, aiming to provide reference for the construction of artificial intelligence radiotherapy imaging database for lung cancer.

ABSTRACT

A case of primary amoebic meningoencephalitis (PAM) treated in the First Affiliated Hospital of Xinxiang Medical University in March 6, 2022 was reported.The proband was a 14-year-old boy, who was admitted to the hospital because of " fever, headache and vomiting for 2 days" . Metagenomic next-generation sequencing (mNGS) was consequently conducted to examine the pathogens in cerebrospinal fluid.Naegleria infection was detected, so the child was diagnosed with PAM.The disease developed rapidly, and the patient died 29 hours after admission.In the paper, a total of 13 studies were reviewed, and 15 children with PAM were reported.Of the reported cases, only 1 case survived, 14 cases died.PAM had a low incidence, a dangerous condition, and high mortality.Most cases were diagnosed by autopsy or pathogen diagnosis in cerebrospinal fluid.This case is confirmed by mNGS of pathogens, and it is rarely reported at home and abroad.

ABSTRACT

Objective:To summarize the clinical and gene mutation characteristics of a child with Cowden syndrome and review the literature.Methods:The clinical data of a child with Cowden syndrome treated in the First Affiliated Hospital of Xinxiang Medical University in June 2020 were analyzed retrospectively.Taking " Cowden syndrome" , " PTEN gene" , " hamartoma polyps" , "child" , " Cowden syndrome and child" and " PTEN and child" as key words, literature was retrieved from Chinese databases (China National Knowledge Internet database and Wanfang database) and the PubMed database from the establishment of the database to March 2021. Results:A 13-year-old male had intermittent abdominal pain and abdominal distension for 5 months.Electron microscopic gastroenteroscopy showed multiple polyps, and focal lymphocyte aggregation and infiltration were found in tissue biopsy.Whole exon sequencing revealed a hemizygous mutation of c. 475 (exon5) A>T in PTEN gene, which led to the transformation of the 159 th amino acid from arginine to tryptophan.The prediction results of the tertiary structure of the protein indicated that the variation might affect the spatial structure of the protein and damage the protein function.According to the clinical characteristics, Cowden syndrome was diagnosed.The pedigree confirmed that the variation was inherited from the mother, who had a similar phenotype.No qualified Chinese report was retrieved.Among 41 English studies on PTEN gene mutation in children, there were only two reports related to pediatric Cowden syndrome.The hemizygous mutation of PTEN gene was not reported. Conclusions:The missense mutation of c. 475 (exon5) A>T in PTEN gene in this study is a novel cause of Cowden syndrome, and the case is the first case report in China.

ABSTRACT

Objective:To evaluate the safety and tolerance of sequential thoracic radiotherapy combined with PD-1/PD-L1 inhibitors in patients with extensive-stage small cell lung cancer (ES-SCLC) after induction systemic therapy.Methods:ES-SCLC patients from a phase I trial and a real-world study were enrolled for those who received thoracic radiotherapy after induction systemic treatment (chemotherapy/chemotherapy combined with PD-1/PD-L1 inhibitors) and consolidated with PD-1/PD-L1 inhibitors. These two studies were both approved by the Ethics Committee of Chinese Academy of Medical Sciences Cancer Hospital (Clinical Trials.gov number, NCT03971214, NCT04947774).Results:Between January 2019 and March 2021, a total of 11 patients with ES-SCLC were analyzed, aged 52-73 years, with a median age of 62 years. Among them, five patients (45.5%) received induction chemotherapy and six patients (54.5%) received chemotherapy combined with PD-1/PD-L1 inhibitor, and then all received intensity-modulated thoracic radiotherapy after evaluation of systemic treatment efficacy. Two patients developed treatment-related grade G3-5 toxicity (18.2%, 1 treatment-related pneumonitis and 1 radiation esophagitis). G 1-G 2 hematologic toxicity, pneumonia, and anorexia were common mild toxicities. Only one patient (9.1%) terminated immunotherapy due to immune-related pneumonitis. During a median follow-up time of 12.5 months (range: 3.5-16.4 months), the median disease progression-free survival and overall survival was 7.4 months (95% CI: 6.9-8.0 months) and 14.6 months (95% CI: 9.0-20.2 months), respectively. Conclusions:Sequential thoracic radiotherapy followed by PD-1/PD-L1 inhibitor is safe and feasible in patients with ES-SCLC after induction therapy. Given that both thoracic radiotherapy and immunotherapy benefits the ES-SCLC in survival, this comprehensive treatment modality warrants further investigation.

ABSTRACT

Objective:To investigate the expression and significance of Toll-like receptor 4 (TLR4) in renal tissue and peripheral blood of children with idiopathic nephrotic syndrome(INS).Methods:The renal biopsy tissues of 78 children with INS diagnosed in the First Affiliated Hospital of Xinxiang Medical University from October 2015 to June 2018 and normal renal tissues of 21 children (control group 1) were collected, and the expressions of TLR4 in the renal tissue was detected by using immunohistochemical method.The expression of TLR4 in different renal pathological types and clinical types of INS was compared, and the correlation of TLR4 with 24-hour urinary protein and serum albumin was analyzed.The expression levels of TLR4 in peripheral blood of children with INS before and after treatment (active stage and remission stage) and 23 healthy children (control group 2) were detected by enzyme linked immunosorbent assay(ELISA). The serum expression levels of TLR4 in different renal pathological types and clinical types of INS were compared, and the correlation of TLR4 with 24-hour urinary protein and serum albumin was analyzed; The correlation between TLR4 expression in renal tubules and in the serum of children with INS was also analyzed.Results:(1)Compared with the expression of TLR4 in normal renal tissues[(0.93±0.26)%], the expression of TLR4 in glomeruli and interstitium of all pathological types of INS [mesangial proliferative glomerulonephritis (MsPGN): (0.93 ± 0.21)%, focal segmental glomerulosclerosis (FSGS): (1.02±0.25)%, membranous glomerulonephritis(MN): (1.03±0.09)%, minimal change disease(MCD): (1.02±0.27)%]was not significantly different ( F=0.741, P=0.562), but the expression of TLR4 in renal tubules[MCD: (82.94±4.62)%, MN: (63.54±1.98)%, MsPGN(42.32±2.97)%, FSGS: (22.60±2.07)%] was significantly increased ( F=1 929.842, P<0.01), Especially, the expression of TLR4 in renal tubules of MCD type INS was significantly higher than that of MN, MsPG N and FSGS [MCD: (82.94±4.62)%, MN: (63.54±1.98)%, MsPGN: (42.32±2.97)%, FSGS: (22.60±2.07)%], and the differences were statistically significant(all P<0.01). TLR4 expression in renal tubules was the highest in steroid-sensitive nephrotic syndrome (SSNS) type and the lowest in INS patients with steroid-resistant nephrotic syndrome (SRNS) type, and the differences were statistically significant( F=220.951, P<0.01). (2)The expression of serum TLR4 in INS children at the active stage [MsPNG: (143.36±12.99) ng/L, FSGS(75.94±7.29) ng/L, MN(210.22±14.66) ng/L, MCD(283.93±21.58) ng/L]was significantly higher than that in INS children at remission stage [MsPNG: (29.51±4.93) ng/L, FSGS(15.66±3.78) ng/L, MN(45.40±5.73) ng/L, MCD(62.29±7.90) ng/L]and control group 2[(0.69 ± 0.33) ng/L], and the differences were statistically significant(all P<0.01); the expression of serum TLR4 in INS children at remission stage was significantly higher than that in the control group 2 ( F=286.287, P<0.01). TLR4 had the highest expression level in serum of MCD type INS children at active and remission stages, followed by MN and FSGS successively.The expression of serum TLR4 was highest in SSNS and lowest in SRNS, and the differences were statistically significant ( F=147.438, P<0.01). (3)The expression of TLR4 in renal tubules of children with INS[(62.82 ±20.94)%]was positively correlated with the expression of TLR4 in serum[(213.26±73.33) ng/L] ( r=0.852, P< 0.05). The expression levels of TLR4 in renal tubules and serum of INS patients at active stage were positively correlated with 24-hour urinary protein level[(123.05±33.55) mg/kg] ( r=0.401, 0.427, all P<0.05), and negatively correlated with serum albumin level[(19.54±3.55)g/L] ( r=-0.602, -0.617, all P<0.05). Conclusions:The expression of TLR4 in renal tubules and serum of children with INS increases, and may be related to different renal pathological types and clinical types of children with INS, as well as disease activity.

ABSTRACT

Objective@#To establish comprehensive laboratory reference intervals for Chinese children.@*Methods@#This was a cross-sectional multicenter study. From June 2013 to December 2014, eligible healthy children aged from 6-month to 17-year were enrolled from 20 medical centers with informed consent. They were assessed by physical examination, questionnaire survey and abdominal ultrasound for eligibility. Fasting blood samples were collected and delivered to central laboratory. Measurements of 15 clinical laboratory parameters were performed, including estradiol (E2), testosterone(T), luteinizing hormone(LH), follicle-stimulating hormone(FSH), alanine transaminase(ALT), serum creatinine(Scr), cystatin C, immunoglobulin A(IgA), immunoglobulin G(IgG), immunoglobulin M(IgM), complement (C3, C4), alkaline phosphatase(ALP), uric acid(UA) and creatine kinase(CK). Reference intervals were established according to central 95% confidence intervals for reference population, stratified by age and sex.@*Results@#In total, 2 259 children were enrolled. Finally, 1 648 children were eligible for this study, including 830 boys and 818 girls, at a mean age of 7.4 years. Age- and sex- specific reference intervals have been established for the parameters. Reference intervals of sex hormones increased gradually with age. Concentrations of ALT, cystatin C, ALP and CK were higher in children under 2 years old. Serum levels of sex hormones, creatinine, immunoglobin, CK, ALP and urea increased rapidly in adolescence, with significant sex difference. In addition, reference intervals were variable depending on assay methods. Concentrations of ALT detected by reagents with pyridoxal 5'-phosphate(PLP) were higher than those detected by reagents without PLP. Compared with enzymatic method, Jaffe assay always got higher results of serum creatinine, especially in children younger than 9 years old.@*Conclusion@#This study established age- and sex- specific reference intervals, for 15 clinical laboratory parameters based on defined healthy children.

ABSTRACT

Objective Tubulointerstitial fibrosis(TIF) is the most important marker reflecting the degree of renal function decline and prognosis and hydrogen sulfide ( H2 S) is crucial in maintaining normal renal function and many diseases of renal injury. The aim of the article was to investigate the effects of exogenous H2 S on the expressions of angiotensinⅡ ( AngⅡ) , proliferating cell nuclear antigen (PCNA) and transforming growth factor beta-1 (TGF-β1) in rats with unilateral ureteral obstruction (UUO). Methods TIF rat model was built with UUO. Ninety-six SD rats were randomly divided into four groups:sham operation group, modelgroup, UUO+low-dose NaHS treatment group ( low dose group) and UUO+high-dose NaHS treatment group ( high dose group) ( n=24, respectively) . Rats in model group were treated with left-side ureteral obstruction and ureteral separation without obstruction was done in sham operation group. UUO rats in two treatment groups were injected intraperitoneally with two different doses of sodium hydrosulfide (NaHS, donor of endogenous H2 S), respectively. HE and Massonstaining and immunohistochemical staining were performed at the 7 d, 14 d and 21 d, respectively. Results In sham operation group, the expressions of AngⅡ, PCNA, and TGF-β1 were found in microamount in tubulointerstitium at each time points. Compared with sham operation group, the expressions of AngⅡ, PCNA and TGF-β1 in model group increased( P<0.01) . While in comparison to model group, the expressions of AngⅡ, PCNA and TGF-β1 decreased in low dose group and high dose group, but no significant differ-ence was found between low dose group and high dose group. Conclusion Exogenous H2 S supplementation can attenuate TIF partly via downregulating the expressions of AngⅡ, PCNA and TGF-β1 .

ABSTRACT

Objective To study the expression and clinical significance of toll-like receptor (TLR) 4 and TLR7 in primary nephrotic syndrome (PNS) of different pathological types in children. Methods Renal expressions of TLR4 and TLR7 were amined and analyzed retrospectively in renal biopsy specimens from 110 PNS patients and 21 healthy controls by immunohisto-chemical method. According to the renal pathologic classification of PNS, the TLR4 and TLR7 expression levels in PNS of dif-ferent types were compared. Results Compared with the renal tissue of healthy controls, the expression level of TLR4 on renal tissue of PNS patients was significantly increased (P<0.01). Among MN, MsPGN and FSGS, the highest expression of TLR4 was observed in MCD (P<0.01). Compared with the renal tissue of healthy controls, the expression level of TLR7 in re-nal tissue of PNS patients was also significantly increased (P<0.01). Among MCD, MN and FSGS, the highest expression of TLR7 was observed in MsPGN (P<0.01). Conclusions TLR4 and TLR7 expression levels are increased in renal tissue of PNS patients and the expression levels may be correlated with renal pathological types.

ABSTRACT

Objectives To observe the expressions ofα-smooth muscle actin (a-SMA) and type III collagen (Col-III) of tubuloin-terstitial ifbrosis(TIF) induced by unilateral ureteral obstruction (UUO) in rat and the intervention effect of supplemental hydrogen sul-ifde (H2S). Methods Ninety-six male Sprague-Dawley rats were randomly divided into 4 groups, sham-operated group, UUO model group, NaHS low-dose group and high-dose group. TIF rat model was established via UUO. After UUO operation, low-dose and high-dose group were intraperitoneally injected twice a day with 1.4μmol/kg and 7.0μmol/kg NaHS, respectively. Sham-operated group and UUO model group were given an equivalent volume of normal saline. Eight rats in each group were killed randomly at 7, 14 and 21 days after UUO operation. The concentration of plasma H2S was detected using deproteinization. Renal tubulointerstitial damage was evaluated with routine Hematoxylin and Eosin staining and Masson staining under microscope. The expressions ofα-SMA, Col-III were measured with immunohistochemistry. Results Compared with sham-operated group, renal tubulointerstitial injury was severer in UUO model group and was alleviated after intervention of NaHS. There was signiifcant difference in tubulointerstitial injury among all groups (P0.05). Conclusions TIF induced by UUO is associated with decreased level of endogenous H2S. H2S supplementation can ameliorate the development of UUO-associated TIF in part through down-regulating the expressions ofα-SMA and Col-III in renal tissues. However, a dose dependent manner between the two doses of exogenous H2S supplementation was not observed.

ABSTRACT

The effects of the combined use of angiotensin converting enzyme inhibitor (ACEI) benazepril and angiotensin II type 1 receptor antagonist (AT1RA) valsartan on apoptosis and the expression of apoptosis-related proteins Fas and FasL in the kidney of rats with adriamycin-induced nephritic glomerulosclerosis was investigated. Uninephrectomy and the injection of adriamycin induced the rat model of glomerulosclerosis. Benazepril (6 mg/kg), valsantan (20 mg/kg), or benazepril (3 mg/kg) plus valsantan (20 mg/kg) was respectively delivered daily by gavage to the rats in three treatment groups for 12 weeks. Apoptosis was examined by means of terminal-deoxynucleotidyl transferase mediated d-UTP nick end labeling (TUNEL). Immunohistochemistry was adopted to detect the expression of Fas and FasL. Software of pathological analysis quantitated the levels of Fas and FasL. The results showed that as compared with those in the control group, the kidneys in the model group had more severe glomerulosclerosis, much more apoptotic cells and higher levels of expression of Fas and FasL. The degree of glomerulosclerosis, the number of apoptotic cells and the levels of expression of Fas and FasL were reduced by benazepril and valsartan. The combined use of benazepril and valsartan had the best therapeutic effect. It was concluded that benazepril and valsartan could suppress the excessive apoptosis of kidney cells by lowering the expression of the apoptosis-related proteins Fas and FasL, so as to postpone the process of glomerulosclerosis. The combined use of benazepril and valsartan has better therapeutic effect.

ABSTRACT

Objective To study the relationships between clinical and endoscopic findings of children with Henoch-Schoenlein purpura ( HSP). Methods All of the 51 cases with HSP from Aug 2000 to Apr 2004 were checked up by endoscopy, either gastroscopy and/or colonoscopy, and analyzed the relationship between clinical and endoscopic fingings. Results Fifteen out of 51 cases had no prominent changes in endoscopies, and 36 cases had different lesions in gastric, duodenal or colonic mucosa. There were 4 cases presented with simple lesion on stomach mucosa and 7 cases on colonic mucosa; and 25 cases had the lesions presented in gastrie, duodenal and/or colonic mucosa. The main findings in mucosa were exudates, erosion and hemorrhage. Conclusion There are obvious lesions in stomach, duodenum and /or colonic mucosa of HSP in children. Sometimes, these lesions happened before the appearance of skin purpura. There are close relationships between the lesions and the clinical manifestations of HSP in children, and therefore the endoscopic check up of HSP in children has very important significance in early diagnosis.
