Objective@#To systematically review the prevalence of iron-deficiency anemia among children aged 0-14 years in China from 2000 to 2020, and to provide a reference for prevention and controlling of IDA among Chinese children.@*Methods@#CNKI, CBM, WanFang Data, VIP databases, PubMed, Embase and Web of Science were electronically searched to collect crosssectional studies on the prevalence of iron deficiency anemia in children aged 0-14 years of China from 2000 to April 2020. Two reviewers independently conducted literature screening, methodological evaluation and data extraction, and used Stata 13.0 software to combine the data to estimate the prevalence. The Q test and I 2 statistics were used to evaluate the heterogeneity of studies. Begg and Egger test were used to evaluater.@*Results@#A total of 60 articles were included, including 122 771 children, among whom 28 693 were sick. Meta-analysis results showed that the total prevalence rate of children aged 0-14 years in China from 2000 to 2020 was 19.9%. The prevalence rate of girls (18.7%) was higher than that of boys (16.9%), and the difference was statistically significant(P<0.05). The prevalence rate was highest in infancy(30.3%), followed by in early childhood(16.7%). From 2006 to 2010, the prevalence rate of children was the highest(22.6%). In recent years, the prevalence rate of children with iron deficiency anemia was lower than before. Mild anemia was found in 88.7% of the children, and moderate or severe anemia was found in 11.3% of the children. The prevalence rate of children in western China was the highest, 31.9% and 28.3% respectively, and the incidence rate in east China(13.1%), south China (14.0%) and northeast China (16.6%) was relatively low. The prevalence rate of rural children (25.6%) was much higher than that of urban children(9.1%), especially in western rural areas.@*Conclusion@#The prevalence of iron-deficiency anemia among children aged 0-14 years in China from 2000 to 2020 is still high and the differences between different regions are significant, so more attention should be paid to the prevention and treatment of iron-deficiency anemia among infants and children in poor areas.

PD-1/PD-L1 blockade in cervical cancer: current studies and perspectives / 医学前沿

Cervical cancer (CC) is the fourth most commonly diagnosed female malignancy and a leading cause of cancer-related mortality worldwide, especially in developing countries. Despite the use of advanced screening and preventive vaccines, more than half of all CC cases are diagnosed at advanced stages, when therapeutic options are extremely limited and side effects are severe. Given these circumstances, new and effective treatments are needed. In recent years, exciting progress has been made in immunotherapies, including the rapid development of immune checkpoint inhibitors. Checkpoint blockades targeting the PD-1/PD-L1 axis have achieved effective clinical responses with acceptable toxicity by suppressing tumor progression and improving survival in several tumor types. In this review, we summarize recent advances in our understanding of the PD-1/PD-L1 signaling pathway, including the expression patterns of PD-1/PD-L1 and potential PD-1/PD-L1-related therapeutic strategies for CC.

Effects of miR-144 on proliferation, apoptosis and cisplatin resistance by targeting MYCN in pediatric neuroblastoma / 中华肿瘤杂志

Objective@#To investigate the effects and mechanisms of miR-144 on proliferation, apoptosis and cisplatin (DDP) resistance of neuroblastoma cells.@*Methods@#Real-time fluorescence quantitative PCR (RT-qPCR) was used to detect the mRNA expressions of miR-144 and MYCN in neuroblastoma cell lines, including SH-SY5Y and SK-N-SH, and human umbilical vein endothelial cells HUVEC. The miR-negative control, miR-144 mimics, si-negative control, si-MYCN, miR-144 mimics and pcDNA, miR-144 mimics and pcDNA-MYCN co-transfected SH-SY5Y cells were described as miR-NC, miR-144, si-NC, si-MYCN, miR-144+ pcDNA and miR-144+ pcDNA-MYCN group, respectively. The half maximal inhibitory concentration (IC50) and cell proliferation were detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) assay. The protein expressions of MYCN, p21, cyclin D1, Bax, Bcl-2 were analyzed by western blot. Cell apoptosis was detected by flow cytometry. The cell fluorescence activity was detected by double luciferase reporter gene assay.@*Results@#Compared with HUVEC cells, the expressions of miR-144 in neuroblastoma cells SH-SY5Y and SK-N-SH significantly decreased, while the mRNA and protein expression of MYCN significantly increased. The IC50 of DDP was 9.16 μg/ml in SH-SY5Y cells. The absorbance value in 490nm (A490 value) of miR-144 group was 0.30±0.03, significantly lower than 0.46±0.03 of miR-NC group. The cell apoptotic rate of miR-144 group was 26.94%±2.01%, significantly higher than 9.68%±0.52% of miR-NC group. The IC50 value of DDP in miR-144 group was 2.95±0.26, significantly lower than 9.23±0.61 of miR-NC group. The expressions of p21, cyclin D1, Bax, Bcl-2 in miR-NC and miR-144 group were 2.67±0.19, 0.41±0.04, 2.12±0.21, 0.18±0.01 and 1.01±0.07, 1.00±0.06, 1.00±0.05, 1.00±0.06, respectively, with statistical significance (all P<0.05). Knockdown of MYCN showed the similar effects with those of miR-144 overexpression in SH-SYSY cells. MiR-144 significantly inhibited the fluorescence activity of ectopic MYCN expressing cells and negatively regulated the expression of MYCN. Overexpression of MYCN can reverse the effects of miR-144 on proliferation inhibition, apoptosis promotion and sensitization of SH-SY5Y cells to DDP.@*Conclusion@#MiR-144 inhibits proliferation, promotes apoptosis and enhances the sensitivity of neuroblastoma cells to DDP through targeting MYCN, which provides a potential treatment for neuroblastoma.

PDCD4 enhances the inhibitory effect of As2O3 on the growth and NF-κB signaling pathway in neuroblastoma cells / 中华肿瘤杂志

Objective@#To investigate the inhibitory effect of programmed cell death factor 4 (PDCD4) on arsenic trioxide (As2O3)-induced cell growth and nuclear factor kappa B (NF-κB) signaling pathway in neuroblastoma.@*Methods@#The PDCD4 overexpression vector was transfected into neuroblastoma cells and detected by fluorescence quantitative PCR and Western blot. As2O3 was used to treat PDCD4 overexpressing neuroblastoma cells. MTT assay was used to measure the proliferation. Colony formation assay was used to determine the cell clone forming ability. Apoptosis was measured by flow cytometry. Western blot was used to detect the expression of NF-κB p65 and cleaved caspase-3 protein in cells.@*Results@#The transfection of PDCD4 overexpression vector significantly increased the expression level of PDCD4 in neuroblastoma cells. The cell survival rates of the control group, PDCD4 group, As2O3 group and As2O3+ PDCD4 group were 100%, (72.14±5.20)%, (62.58±3.14)% and (40.87±2.47)%, respectively. The colony formation rates in these four groups were (91.25±8.36)%, (65.32±7.14)%, (57.23±5.28)% and (37.14±3.64)%, respectively. In addition, the cell apoptotic rates of these four groups were (3.57±0.24)%, (28.64±3.20)%, (36.41±4.58)% and (49.65±5.27)%, respectively. Therefore, overexpression of PDCD4 in the absence or presence of As2O3 inhibited cell proliferation and clone formation ability, while promoted apoptosis. Furthermore, the expression levels of cleaved caspase-3 in the control group, PDCD4 group, As2O3 group and As2O3+ PDCD4 group were 0.21±0.03, 0.30±0.02, 0.43±0.05 and 0.57±0.06, respectively. And the expression levels of NF-κB p65 protein were 0.68±0.04, 0.52±0.03, 0.43±0.04, and 0.32±0.02, respectively. Compared with the control group, the expression levels of NF-κB p65 protein in PDCD4 group, As2O3 group and As2O3+ PDCD4 group were significantly decreased (P<0.05), whereas the expression level of cleaved Caspase-3 protein was significantly increased (P<0.05). The changes in As2O3+ PDCD4 group were more significant than those in PDCD4 group and As2O3 groups (both P<0.05).@*Conclusion@#PDCD4 enhances the inhibitory effect of As2O3 on the growth and NF-κB signaling pathway in neuroblastoma cells.

Correlation between the expression level of coiled-coil domain-containing protein 80 and obesity / 中华预防医学杂志

<p><b>OBJECTIVE</b>To explore the relationship between expression of coiled-coil domain-containing protein 80(CCDC80) and obesity in serum and adipose tissues.</p><p><b>METHODS</b>A cross-sectional survey was conducted in a hospital in Tangshan in September 2010. 100 people including 78 healthy people and 22 with type-2 diabetes were recruited. Another 36 female patients with benign tumor of Obstetrics and Gynecology were also recruited. Demographic characteristics and serum samples were collected from all subjects, basic biochemical indicators were tested. All subjects were divided into 'Normal Weight' and 'Overweight and Obese' according to their BMI (BMI <24.0 kg/m(2); BMI≥24 kg/m(2)). Serum CCDC80 of the 100 subjects was detected by ELISA. Visceral and subcutaneous fat were derived from the other 36 female subjects, and Real-time PCR was used to detect CCDC80 mRNA expression in adipose tissues. Pearson correlation and multiple linear regression were used to analyze the correlation between serum or adipose CCDC80 expression and waist, BMI, and other biochemical indicators.</p><p><b>RESULTS</b>The age of 100 subjects was (52.9±8.4) years old. 44% of them were women (44 cases) and 56% of them were men (56 cases). After dividing them into three groups according to their BMI, covariance analysis were conducted, and age and gender were adjusted. The HDL-C level was significantly different among three groups (F = 10.73, P < 0.001): 'Overweight and obese combined with diabetes' group ((0.90±0.06) mmol/L)< 'Overweight and obese' group ((1.14±0.04) mmol/L) < 'Normal weight' group ((1.28±0.05) mmol/L). The adjusted expression of serum CCDC80 of the 100 subjects was (5.84±0.16) pg/ml, (5.81±0.98) pg/ml among men and (5.97±0.89) pg/ml among women, and there was no significant difference (t = -0.812, P = 0.419) between genders. ANOVA revealed that there was no significant differences of the expression of serum CCDC80 among three groups (F = 1.06, P = 0.351), 'Normal weight' group was (5.84±0.16) pg/ml, 'overweight and obese' group was (6.11±0.14) pg/ml, and 'Overweight and obese combined with diabetes' group was (5.84±0.19) pg/ml. The analysis showed that FBG had a negative correlation with serum CCDC80 (R(b) = -0.223, P = 0.026). Multivariate linear regression had a similar result, with 1 mmol/L increase of serum FBG, serum CCDC80 decreases for 0.24 pg/ml (β = -0.24, 95% CI: -0.21--0.02). There was also a negative correlation between serum CCDC80 and FBG in overweight and obese people (R(a) = -0.368, P = 0.013). Besides, CCDC80 mRNA was detected in both subcutaneous and visceral adipose tissue of 36 cases, the expression level was 0.06±0.02 for subcutaneous fat, was 0.05±0.04 for visceral fat, and the expression in visceral fat was lower (0.05±0.03) than that in subcutaneous fat (0.06±0.03) (t = 2.50, P = 0.025) among overweight and obese group. There was a negative correlation between waist and visceral CCDC80 mRNA expression (r = -0.472, P = 0.035).</p><p><b>CONCLUSION</b>This study suggested that CCDC80 may be involved in energy and insulin metabolism, and plays a protective role in obesity and diabetes.</p>

Objective To study the changes of cerebral function and pathological morphology before and after the antiparasit-ic treatment with albendazole and praziquantel in patients with cerebral cysticercosis. Methods The data of EEG and neuroimag-ing of 412 patients with cerebral cysticercosis were retrospectively analyzed. Results Before the treatment,the mild abnormali-ty,moderate abnormality,and severe abnormality were observed in 40.53%,45.63% and 13.84% of the patients respectively, which mainly showed the diffuse or focal irregular slow waves,or epileptiform discharges found in the abnormal brain waves. CT/MRI manifestation could be divided into six types,including single sacculus type(23.59%),multiple sacculus type(44.42%), encephalitis type(13.59%),coexistence of macrocyst and sacculus type(4.85%),calcification type(2.18%),and mixed type (11.41%). After 3 courses of the treatment,the normal and improved EEGs were observed in 79.85%and 20.15%,respectively. CT/MRI showed the foci being all absorbed(77.18%),being most absorbed(20.63%),and being no changes(20.18%)which were calcified focus. When cerebral cysticercosis were in acute stage(the single and multiple sacculus type,encephalitis type, and macrocyst and sacculus coexistence type),the therapeutic effect was good;while in the mixed type,the therapeutic effect was relatively poor. If cysticercosis were in the calcification stage,the patients only needed the heteropathy. Conclusions In the pa-tients with cerebral cysticercosis,EEGs show the mild to severe abnormalities,and CT/MRI mainly shows the multiple sacculus type. After the treatment,the abnormal EEGs are gradually recovered and the low density foci can be all absorbed,but some calci-fied focus still exist in some patients.

Objective To explore the safety and effectiveness of dexamethasone and calcium gluconate combined with oxytocin to prevent postpartum hemorrhage.Methods 128 maternal patients with full-term delivery were divided the patients into two parts randomly:the control group and the observation group,of which contained three groups(A,B,C).The patients were all given 20 u oxytocin.As to observation,group A:before 10-15min of cutting skin,give 10mg of dexamethasone and 10 ml 10％ calcium gluconate rapid intravenous infusion,group B:give 10mg intravenous infusion of dexamethasone after babies were boro,group C:before 10 ～ 15min of cutting skin,give 10mg of dexamethasone and 10ml 10％ calcium gluconate rapid intravenous infusion and then give 10mg dexamethasone after babies were born.The control group wasn't given that medicine,and only give them 20 u oxytocin when babies were born.At last,give contrast of total amount of bleeding,ill reflecting of medicine and the other symptom after 24h.Results The amount of bleeding of observation group A,B,C were (277.3 ± 44.5) ml,(286.8 ± 52.7) ml,(301.8 ±60.9) ml,respectively.The amount of bleeding of the control group was (422.9 ± 78.2) ml.The observation group and control group had significant differences(t =-0.699,0.481,-0.407,all P ＜ 0.01),and there was no significant difference between group A,B,and C (P ＞ 0.05).And this two groups had no bad reflection and the other symptoms.Conclusion Dexamethasone and calcium gluconate combined with oxytocin to prevent postpartum hemorrhage has great efficacy and safety.This method must be extended.
