Advances in systemic immune inflammatory indices in non-small cell lung cancer: A review.

Lung cancer is one of the most prevalent cancers globally, with non-small cell lung cancers constituting the majority. These cancers have a high incidence and mortality rate. In recent years, a growing body of research has demonstrated the intricate link between inflammation and cancer, highlighting that inflammation and cancer are inextricably linked and that inflammation plays a pivotal role in cancer development, progression, and prognosis of cancer. The Systemic Immunoinflammatory Index (SII), comprising neutrophil, lymphocyte, and platelet counts, is a more comprehensive indicator of the host's systemic inflammation and immune status than a single inflammatory index. It is widely used in clinical practice due to its cost-effectiveness, simplicity, noninvasiveness, and ease of acquisition. This paper reviews the impact of SII on the development, progression, and prognosis of non-small cell lung cancer.

Relationship between lumbar disc herniation and Roussouly classification in the sagittal alignment of the spine and pelvis in young people.

Background: The sagittal plane of spine-pelvis morphology of adult patients with lumbar disc herniation (LDH) differs from that of normal people. There is a correlation between abnormal sagittal plane morphology and adult LDH. This study aimed to investigate the relationship between LDH in young people and the Roussouly classification in the sagittal alignment of the spine and pelvis. Methods: A total of 126 patients with LDH hospitalized in our tertiary hospital between January 2020 and January 2021 who met the inclusion and exclusion criteria were retrospectively analyzed in a cross-sectional study. Participants were grouped according to the spinal level of disc herniation (L4/5 group, L5/S1 group, L3/4 group). Pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) of all cases were measured using standing lateral spinal radiographs. Facet joint angles (FJA) were measured using lumbar computed tomography (CT) horizontal radiographs, and the height of the anterior, middle, and posterior margins of the herniated disc was measured using sagittal radiographs. The classification of Pfirrmann disc degeneration was determined via magnetic resonance imaging (MRI) film of the lumbar region. Roussouly classification was performed according to sagittal plane morphology, and data were analyzed among each group. Results: In all, 126 patients aged from 18 to 40 years, with an average age of 31.04±5.886 years were included. There were 63 cases of L4/5 disc herniation, 59 cases of L5/S1 herniation, and 4 cases of L3/4 herniation. There were 35 cases of epiphyseal separation. The Roussouly classification included 21 cases of type 1, 56 cases of type 2, 32 cases of type 3, 4 cases of type 4, and 13 cases of type 3 + anteverted pelvis (type 3-AP). The L4/5 disc herniation group had significantly more types 2 and 3 than the other groups, and the L5/S1 disc herniation group had significantly more types 1 and 2 than the other groups. There were no significant differences in the Pfirrmann grade of intervertebral disc degeneration; epiphyseal separation; the height of anterior, middle, and posterior margins of the herniated disc; the difference between left and right facet angle and bilateral facet angle; and the thoracic kyphosis (TK) value among any of the groups (P>0.05). There were significant differences in PI, PT, SS, lumbar lordosis (LL), and height of the anterior and posterior margins of the intervertebral space among all groups (P<0.05). PI values were grouped at 50°; PT, SS, and LL were significantly different (P<0.05), whereas TK values were not significantly different between the 2 groups (P>0.05). SS values were grouped at 35°, and there were significant differences in PI, TK, and LL between the 2 groups (P<0.05). According to the disc herniation segment, the patients were divided into L4/5 and L5/S1 groups. There were significant differences in PI, PT, anterior edge height, anterior to posterior edge height, left facet angle, right facet angle, and bilateral facet angle (P<0.05). Conclusions: LDH is common in L4/5 and L5/S1 segments. The incidence of Roussouly type 1 and 2 LDH is significantly higher than other types, and type 4 is the lowest. Small PI and small SS are more obvious in the L5/S1 segment. L5/S1 disc herniation is more common in patients with Roussouly type 1 and 2 classifications, whereas L4/5 disc herniation is more frequent in patients with Roussouly type 2 and 3 classifications.

TAK-242 protects against oxygen-glucose deprivation and reoxygenation-induced injury in brain microvascular endothelial cells and alters the expression pattern of lncRNAs.

Background: Deep hypothermic circulatory arrest (DHCA) is a technique used during the surgical treatment of aneurysms of the thoracic aorta in adult patients, and complex congenital heart disease in neonates. And brain microvascular endothelial cells (BMECs) are essential components of the cerebrovascular network and participate in maintaining the blood-brain barrier (BBB) and brain function. In our previous study, we found that oxygen-glucose deprivation and reoxygenation (OGD/R) activated Toll-like receptor 4 (TLR4) signaling in BMECs, and induced pyroptosis and inflammation. In this study, we further investigated the potential mechanism of ethyl(6R)-6-[N-(2-Chloro-4-fluorophenyl) sulfamoyl] cyclohex-1-ene-1-carboxylate (TAK-242) on BMECs under OGD/R, as in patients with sepsis, the TAK-242 was tested in clinical trials. Methods: To confirm the function of TAK-242 on BMECs under OGD/R, cell viability, inflammatory factors, inflammation-associated pyroptosis, and nuclear factor-κB (NF-κB) signaling were determined using Cell Counting Kit-8 (CCK-8) assay, enzyme-linked immunosorbent assay (ELISA), and western blotting, respectively. To investigate the lncRNAs associated with TLR4 during OGD/R, long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) expression patterns were profiled with RNA deep sequencing. Moreover, to confirm whether lncRNA-encoded short peptides, liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used. Results: Relative control group, OGD/R inhibited the cell viability, increased the section of inflammatory factors secretion, including IL-1ß, IL-6, and TNF-α, and promoted the pathways of TLR4/NLRP3/Caspase-1 and TLR4/NF-κB. However, TAK-242 + OGD/R group promoted OGD/R cell viability, decreased OGD/R-induced inflammatory factors secretion, and inhibited the pathways of TLR4/NLRP3/Caspase-1 and TLR4/NF-κB. In addition, AABR07000411.1, AABR070006957.1, and AABR070008256.1 were decreased in OGD/R cells compared with controls, but TAK-242 restored their expression under OGD/R condition. AABR07000473.1, AC130862.4, and LOC10254972.6 were induced by OGD/R, but were suppressed in TAK-242 + OGD/R cells compared with OGD/R. Moreover, AABR07049961.1, AC127076.2, AABR07066020.1, and AABR07025303.1-encoded short peptides were dysregulated in OGD/R cells, and TAK-242 attenuated the dysregulation of AABR07049961.1, AC127076.2, and AABR07066020.1-encoded short peptides. Conclusions: TAK-242 alters the expression pattern of lncRNAs in OGD/R cells, and differently expressed lncRNAs may exert a protective effect against OGD/R injury through a mechanism of competing endogenous RNA (ceRNA) and encoding short peptides. These findings maybe provide a new theory basis for the treatment of DHCA.

Role of exosomes in non-small cell lung cancer and EGFR-mutated lung cancer.

As an important mediator of information transfer between cells, exosomes play a unique role in regulating tumor growth, supporting vascular proliferation, tumor invasion, and metastasis. Exosomes are widely present in various body fluids, and therefore they can be used as a potential tool for non-invasive liquid biopsy. The present study reviews the role of exosomes in liquid biopsy, tumor microenvironment formation, and epithelial-mesenchymal transition in non-small cell lung cancer (NSCLC). By targeting epidermal growth factor receptor (EGFR) therapy as a first-line treatment for patients with NSCLC, this study also briefly describes the occurrence of EGRF+ exosomes and the role of exosomes and their contents in non-invasive detection and potential therapeutic targets in EGFR-mutated lung cancer.

Role of exosomal noncoding RNA in esophageal carcinoma.

Esophageal cancer is a common malignant tumor with a high degree of malignancy. Understanding its pathogenesis and identifying early diagnostic biomarkers can significantly improve the prognosis of esophageal cancer patients. Exosomes are small double-membrane vesicles found in various body fluids containing various components (DNA, RNA, and proteins) that mediate intercellular signal communication. Non-coding RNAs are a class of gene transcription products that encode polypeptide functions and are widely detected in exosomes. There is growing evidence that exosomal non-coding RNAs are involved in cancer growth, metastasis and angiogenesis, and can also be used as diagnostic and prognostic markers. This article reviews the recent progress in exosomal non-coding RNAs in esophageal cancer, including research progress, diagnostic value, proliferation, migration, invasion, and drug resistance, provide new ideas for the precise treatment of esophageal cancer.

CircFBXW7 Inhibits Proliferation, Migration, and Invasion of Nonsmall Cell Lung Cancer Cells by Regulating miR-492.

Background: CircFBXW7 has been determined to be involved in various cancers; however, its role in nonsmall cell lung cancer (NSCLC) remains unclear. This study examined the function and potential mechanism of circFBXW7 in NSCLC. Methods: The structure of circFBXW7 was verified via RT-PCR and Sanger sequencing. The expression of circFBXW7 in NSCLC was determined by qRT-PCR. The effect of circFBXW7 overexpression on the proliferation, migration, and invasion of NSCLC cells was examined by CCK-8 and Transwell assays. Furthermore, a circFBXW7-miRNA network was established to explore their interaction. Predicted miRNA was determined by qRT-PCR. Moreover, the miRNA mimics were synthesized, wherein its effect on proliferation, migration, and invasion of NSCLC cells overexpressed circFBXW7 was assessed. Results: The circularity of circFBXW7 was verified. The expression of circFBXW7 was found to be downregulated in NSCLC cells compared with that in normal human lung epithelial BEAS-2B cells. Overexpression of circFBXW7 reduced cell proliferation, migration, and invasion. Furthermore, according to the circFBXW7-miRNA network prediction and qRT-PCR validation, miR-492 was identified to be the target of circFBXW7. The inhibitory effect of circFBXW7 overexpression on cell proliferation, migration, and invasion was reversed by miR-492 mimics. Conclusion: CircFBXW7 is downregulated in NSCLC. CircFBXW7 inhibits NSCLC cells proliferation, migration, and invasion by regulating miR-492.

Comparison of acute pneumonia caused by SARS-COV-2 and other respiratory viruses in children: a retrospective multi-center cohort study during COVID-19 outbreak.

BACKGROUND: Until January 18, 2021, coronavirus disease-2019 (COVID-19) has infected more than 93 million individuals and has caused a certain degree of panic. Viral pneumonia caused by common viruses such as respiratory syncytial virus, rhinovirus, human metapneumovirus, human bocavirus, and parainfluenza viruses have been more common in children. However, the incidence of COVID-19 in children was significantly lower than that in adults. The purpose of this study was to describe the clinical manifestations, treatment and outcomes of COVID-19 in children compared with those of other sources of viral pneumonia diagnosed during the COVID-19 outbreak. METHODS: Children with COVID-19 and viral pneumonia admitted to 20 hospitals were enrolled in this retrospective multi-center cohort study. A total of 64 children with COVID-19 were defined as the COVID-19 cohort, of which 40 children who developed pneumonia were defined as the COVID-19 pneumonia cohort. Another 284 children with pneumonia caused by other viruses were defined as the viral pneumonia cohort. The epidemiologic, clinical, and laboratory findings were compared by Kolmogorov-Smirnov test, t-test, Mann-Whitney U test and Contingency table method. Drug usage, immunotherapy, blood transfusion, and need for oxygen support were collected as the treatment indexes. Mortality, intensive care needs and symptomatic duration were collected as the outcome indicators. RESULTS: Compared with the viral pneumonia cohort, children in the COVID-19 cohort were mostly exposed to family members confirmed to have COVID-19 (53/64 vs. 23/284), were of older median age (6.3 vs. 3.2 years), and had a higher proportion of ground-glass opacity (GGO) on computed tomography (18/40 vs. 0/38, P < 0.001). Children in the COVID-19 pneumonia cohort had a lower proportion of severe cases (1/40 vs. 38/284, P = 0.048), and lower cases with high fever (3/40 vs. 167/284, P < 0.001), requiring intensive care (1/40 vs. 32/284, P < 0.047) and with shorter symptomatic duration (median 5 vs. 8 d, P < 0.001). The proportion of cases with evaluated inflammatory indicators, biochemical indicators related to organ or tissue damage, D-dimer and secondary bacterial infection were lower in the COVID-19 pneumonia cohort than those in the viral pneumonia cohort (P < 0.05). No statistical differences were found in the duration of positive PCR results from pharyngeal swabs in 25 children with COVID-19 who received antiviral drugs (lopinavir-ritonavir, ribavirin, and arbidol) as compared with duration in 39 children without antiviral therapy [median 10 vs. 9 d, P = 0.885]. CONCLUSION: The symptoms and severity of COVID-19 pneumonia in children were no more severe than those in children with other viral pneumonia. Lopinavir-ritonavir, ribavirin and arbidol do not shorten the duration of positive PCR results from pharyngeal swabs in children with COVID-19. During the COVID-19 outbreak, attention also must be given to children with infection by other pathogens infection.

SP1-induced lncRNA FOXD3-AS1 contributes to tumorigenesis of cervical cancer by modulating the miR-296-5p/HMGA1 pathway.

Long noncoding RNAs (lncRNAs) have drawn growing attention due to their regulatory roles in various diseases, including tumors. Recently, lncRNA FOXD3 antisense RNA 1 (FOXD3-AS1) was shown to be overexpressed in colon adenocarcinoma and glioma, exerting oncogenic functions. However, its expression and effects in cervical cancer (CC) remained unknown. In this research, our group first reported that the levels of FOXD3-AS1 were distinctly elevated in CC samples and cell lines. The distinct upregulation of FOXD3-AS1 was associated with lymphatic invasion, distant metastasis, and International Federation of Gynecology and Obstetrics stage, and also predicted poor clinical results of CC patients. Next, transcription factor SP1 was demonstrated to resulting in the upregulation of FOXD3-AS1 in CC. Functional assays indicated that knockdown of FOXD3-AS1 distinctly suppressed CC progression via affecting cell proliferation, cell apoptosis, and metastasis. Moreover, mechanistic studies suggested that FOXD3-AS1 acted as an endogenous sponge by directly binding miR-296-5p, resulting in the suppression of miR-296-5p. In addition, we also reported that high mobility group A, a direct target of miR-296-5p, could mediate the tumor-promotive effects that FOXD3-AS1 displayed. Overall, our present study might help to lead a better understanding of the pathogenesis of CC, provide a novel possible tumor biomarker, and probe the feasibility of lncRNA-directed treatments for CC.

[Application of enhanced recovery after surgery in postoperative rehabilitation of osteoporotic lumbar compression fractures with percutaneous vertebroplasty or percutaneous kyphoplasty].

OBJECTIVE: To study effects of postoperative regular training of core muscle strength guided by the concept of enhanced recovery after surgery (ERAS) on the rehabilitation of elderly patients with osteoporotic lumbar vertebral compression fracture after vertebroplasty (PVP) and kyphoplasty(PKP). METHODS: Ninety-four elderly patients with osteoporotic lumbar compression fractures who underwent PKP or PVP from January 2016 to January 2018 and met inclusion criteria were divided into observation group and control group. All the patients were treated with routine anti osteoporosis therapy after operation. There were 47 patients in the observationgroup, including 18 males and 29 females, with an average age of (62.62±3.21) years old;in the control group, there were 47 cases, including 17 males and 30 females, with an average age of (62.38±2.84) years old. The patients in the control group were trained by traditional way, and the patients in observation group were instructed to conduct regular training of core muscle strength according to ERAS concept. The patients were followed up for 1, 3 and 6 months after operation. Patients' conditions were quantitatively evaluated according to Barthel scale, JOA low back pain score and Oswestry Disability Index, and the differences in treatment effects between two groups were statistically analyzed and compared. RESULTS: All the patients were followed up, and the Barthel scale, JOA low back pain score and Oswestry Disability Index score of the observation group were all better than those of the control group on the 1st and the 3rd months after surgery(P< 0.05). The Oswestry Disability Index score of the observation group on the 6th month after surgery were superior to those of the control group (P<0.05). However, there was no significantly difference in JOA low back pain score and Barthel scale between two groups at 6 months after surgery (P>0.05). The comparison of Barthel scale, JOA low back pain score and Oswestry Disability Index before and after the operation of 1, 3 and 6 months between the two groups were significantly improved (P<0.05). CONCLUSION: Early regular core strength training has a positive effect on early functional recovery and improvement of life ability after PKP or PVP for elderly patients with osteoporotic lumbar compression fractures, which is in line with the concept of accelerated rehabilitation surgery.

[Preliminary application of CPC/PMMA composite bone cement in kyphoplasty for the elderly].

OBJECTIVE: From the perspective of clinical application to analyze the effectiveness and reliability of CPC/PMMA bone cement in percutaneous kyphoplasty (PKP) for the treatment of elderly patients with osteoporotic thoracolumbar fractures. METHODS: A retrospective analysis was performed on 62 patients with osteoporotic compression fracture of single-vertebral thoracic or lumbar segment who underwent PKP surgery and had a bone density less than or equal to -3.0 SD from February 2016 to December 2016. Among them, 23 patients were in CPC/PMMA group, with an average age of (77.6±2.2) years old, 39 patients in PMMA group, with an average age of (77.1±1.1) years old. The indexes between two groups were compared, including the visual analogue scale (VAS), height ratio of anterior vertebra (AVHR), local Cobb angle, cement leakage, new adjacent vertebral fracture(NAVF). RESULTS: There were no significant difference in gender, age, follow-up time and preoperative VAS, AVHR, local Cobb angle between two groups (P>0.05), at the 1 day after operation, VAS, AVHR, local Cobb angle in all patients got obvious improvement (P<0.05), which was no significant difference at 1 day after operation and final follow-up (P>0.05). At the same time, there was no statistically significant difference in the incidence of new adjacent vertebral fracture and cement leakage (P>0.05). The pain in both groups continued to improve at follow up after operation (P<0.05), the local Cobb angle increased (P<0.05) and AVHR decreased slightly (P<0.05). However, the images of conventional methods (X-ray or CT) could not find signs about CPC degeneration and new bone ingrowth. CONCLUSION: CPC/PMMA composite bone cement is safe and reliablein PKP for treatment of elderly patients with osteoporotic thoracolumbar fractures, which can effectively relieve pain and maintain vertebral body stability. It has the same curative effect as PMMA bone cement. It was worthy to research more in future, although no direct evidences support the CPC/PMMA composite bone cement can reduce the incidence of adjacent vertebral fracture, CPC degeneration or new bone ingrowth.

Efficacy of unilateral transverse process-pedicle and bilateral puncture techniques in percutaneous kyphoplasty for Kummell disease.

In the present study, the efficacy of unilateral transverse process-pedicle and bilateral puncture techniques in percutaneous kyphoplasty (PKP) for Kummell disease was compared. Between March 2015 and June 2017, 63 patients with Kummell disease were recruited and underwent PKP with two different puncture techniques: A total of 38 patients were treated by unilateral transverse process-pedicle PKP and 25 patients were treated by bilateral PKP. The operative time, intra-operative fluoroscopy time, volume of bone cement injection and bone cement leakage were recorded. Prior to surgery and 1 day post-surgery, the visual analogue scale (VAS) pain score and Oswestry disability index (ODI) were determined, and the vertebral body height and Cobb angle were measured. The results indicated that the incidence of bone cement leakage in the unilateral group was similar with the bilateral group (15.79% vs. 16.00%), with no statistically significant difference between the two groups. None of the patients in the two groups had any obvious damage of the spinal cord. The operative time, intra-operative fluoroscopy time and volume of bone cement injection in the unilateral group were lower than those in the bilateral group. A chest X-ray examination at 1 day post-surgery revealed no pulmonary embolism in the two groups. The VAS score, ODI, vertebral body height and Cobb angle were significantly improved in the unilateral and bilateral groups at 1 day post-surgery and at the last follow-up (12 months post-surgery) as compared with these parameters prior to surgery. In conclusion, the unilateral transverse process-pedicle and bilateral puncture techniques in PKP exhibited good efficacy as a treatment for Kummell disease. The operative time, intra-operative fluoroscopy time and volume of bone cement injection were lower in the unilateral group.

[Clinical comparative study of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease].

OBJECTIVE: By comparing the clinical efficacy of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease to explore a more suitable fixed segment for the disease. METHODS: The clinical data of 46 patients with single-segment thoracic and lumbar spine III stage Kümmell disease treated from July 2013 to December 2016 were retrospectively analyzed. Forty-six patients were divided into short-segment fixation group(one vertebra above and below the diseased vertebra) and long-segment fixation group(two vertebrae on the upper and lower of the diseased vertebra) according to different methods of cement stick fixation. There were 25 patients in the short-segment fixation group, including 9 males and 16 females, with an average age of (75.3±4.5) years old, lumbar spine bone mineral density T-value of (-3.1±0.3) g/cm³, follow-up time of (13.0±2.3) months; there were 21 patients in long-segment fixation group, 6 males and 15 females, with an average age of (74.5±3.9) years old, lumbar spine bone mineral density T-value of (-3.2±0.3) g/cm³, follow-up time of (14.7±3.6) months.The gender, age, follow-up time, operation time, intraoperative blood loss, cement leakage, and the rate of adjacent vertebrae fractures were compared between two groups, as well as pain VAS score, ODI, and kyphosis angle before and after surgery. RESULTS: There were no significant differences in age, gender, bone density, pain VAS score, ODI, and kyphosis between two groups before surgery. The operation time and intraoperative blood loss of short-segment fixation group were less than that of long-segment fixation group. The pain VAS score, ODI and kyphosis of the two groups were significantly improved at 7 days after the operation and at the latest follow-up, there was no significant difference between two groups. There were no significant differences in bone cement leakage(9/25 vs 11/21) and adjacent vertebrae fractures(4/25 vs 3/21). CONCLUSIONS: Both long-segment fixation and short-segment fixation can effectively relieve pain, correct kyphosis, improve functional index, and achieve better clinical results, but short-segment fixation has less operation time and less intraoperative blood. So single-segment thoracic and lumbar spine III stage Kümmell disease does not need to extend the fixed segment, short-segment fixation is more in line with clinical needs and worthy of further study.

[Influence of cow's milk protein allergy on the diagnosis of functional gastrointestinal diseases based on the Rome IV standard in infants and young children].

OBJECTIVE: To study the influence of cow's milk protein allergy (CMPA) on the diagnosis of functional gastrointestinal diseases (FGID) based on the Rome IV standard in infants and young children. METHODS: A total of 84 children aged 1 month to 3 years who were diagnosed with CMPA were enrolled as the case group, and 84 infants and young children who underwent physical examination and had no CMPA were enrolled as the control group. The pediatricians specializing in gastroenterology asked parents using a questionnaire for the diagnosis of FGID based on the Rome IV standard to assess clinical symptoms and to diagnose FGID. RESULTS: The case group had a significantly higher incidence rate of a family history of allergies than the control group (P<0.05). In the case group, 38 (45%) met the Rome IV standard for the diagnosis of FGID, while in the control group, 13 (15%) met this standard (P<0.05). According to the Rome IV standard for FGID, the case group had significantly higher diagnostic rates of reflex, functional diarrhea, difficult defecation, and functional constipation than the control group (P<0.05). The children who were diagnosed with FIGD in the control group were given conventional treatment, and those in the case group were asked to avoid the intake of cow's milk protein in addition to the conventional treatment. After 3 months of treatment, the case group had a significantly higher response rate to the treatment than the control group (P<0.05). CONCLUSIONS: In infants and young children, CMPA has great influence on the diagnosis of FGID based on the Rome IV standard. The possibility of CMPA should be considered during the diagnosis of FGID.

[Risk factors for iron deficiency anemia in infants aged 6 to 12 months and its effects on neuropsychological development].

OBJECTIVE: To study the risk factors for moderate and severe iron deficiency anemia (IDA) in infants aged 6-12 months, and to preliminarily investigate the effects of IDA on the neuromotor development and temperament characteristics of infants. METHODS: A total of 326 infants aged 6-12 months with IDA were classified into three groups: mild IDA (n=176), moderate IDA (n=111), and severe IDA (n=39) according to the severity of anemia. The risk factors for moderate or severe IDA were investigated by multivariate logistic regression analysis. Three hundred and forty-six infants without IDA who showed matched age, sex, and other backgrounds were selected as the control group. The Gesell Development Diagnosis Scale was used to evaluate children's mental development. The Temperament Scale for infants was used for evaluating children's temperament. RESULTS: The univariate analysis showed that the severity of IDA was associated with sex, birth weight, gestational age, multiple birth, maternal anemia during pregnancy, and mother's lack of knowledge about IDA (P<0.05). Setting the mild IDA group as control, the multivariate logistic regression analysis showed that multiple birth, premature birth, low birth weight (<2500 g), maternal anemia during pregnancy, breast feeding, and mother's lack of knowledge about IDA were the risk factors for severe IDA (OR>1; P<0.05); premature birth, breast feeding, and mixed feeding were the risk factors for moderate IDA (OR>1; P<0.05). The IDA group had significantly lower scores in Gesell general development quotient, gross motor, adaptive behavior, and fine motor than the control group (P<0.05). The IDA group had higher percentages of children with difficulty and intermediate difficulty temperaments than the control group (P<0.05). The IDA group had significantly higher scores in activity level, rhythmicity, adaptability, and perseverance than the control group (P<0.05). CONCLUSIONS: The severity of IDA is associated with premature birth, multiple birth, low birth weight, feeding pattern, maternal anemia during pregnancy and mother's lack of knowledge about IDA in infants aged 6-12 months. Infants with IDA have delayed neuromotor development and most of them have negative temperaments. More attention should be paid to mental and behavior problems for the infants. It is necessary to provide guidance for their parents in feeding and education.
