ABSTRACT
OBJECTIVE To study the effects of Hugan buzure formula （HBF） on intrahepatic cholestatic liver injury in rats and its potential mechanism. METHODS Rats were randomly divided into control group， model group， ursodeoxycholic acid （UDCA） group （positive control， 60 mg/kg ） and HBF low-dose， middle-dose and high-dose groups （HBF-L， HBF-M， HBF-H groups， 0.4， 0.8， 1.6 g/kg ）， with 6 rats in each group. The rats in each drug group were given the corresponding drug solution intragastrically， once a day， for 7 consecutive days. The rats in the control group and the model group were given equal volumes of water intragastrically. On the 5th day， except for the control group， the rats in other groups were single intragastrically administered with alpha-naphthyl isothiocyanate olive oil solution （100 mg/kg） to establish the model. After 48 h of modeling， the contents of liver function indexes （aspartate aminotransferase， alanine aminotransferase， alkaline phosphatase， total bile acid， total bilirubin， direct bilirubin） and oxidative stress indexes [malondialdehyde （MDA）， glutathione （GSH）， superoxide dismutase] in serum of rats were detected； the pathological changes of liver tissue were observed. The mRNA expressions of inflammation-related factors [tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）] and farnesoid X receptor （FXR） signaling pathway-related factors [FXR， small heterodimer partner （SHP）， multidrug resistance protein 2 （MRP2）， bile salt export pump （BSEP）， Na+-taurocholate cotransporting polypeptide （NTCP）， organic anion-transporting polypeptide 2 （OATP2） and cholesterol 7α-hydroxylase （CYP7A1）]， the expressions of FXR signaling pathway-related proteins （FXR， MRP2， BSEP， NTCP） and nuclear factor- κB p65 （NF- κB p65） in liver tissue were detected.RESULTS Compared with the model group， the contents of liver function indexes and the level of MDA in serum， the mRNA expressions of the above inflammation-related factors and CYP7A1， and the relative expression of NF-κB p65 in liver tissue were significantly decreased； the levels of GSH in serum， the mRNA expressions of FXR， SHP， MRP2， BSEP， NTCP and OATP2， and the relative expressions of FXR， MRP2， BSEP and NTCP in liver tissue were significantly increased （P＜0.05 or P＜0.01）； the pathological changes of liver tissue were significantly improved. Only some indexes in HBF-L group， HBF-M group and UDCA group were significantly reversed （P＜0.05 or P＜0.01）. CONCLUSIONS HBF can prevent intrahepatic cholestatic liver injury in rats， and the effects may be related to the activation of FXR signaling pathway and the reduction of inflammation and oxidative stress.

ABSTRACT
Objective:To investigate different sleep duration and glucose and lipid metabolism levels in residents of a community in Urumqi.Methods:Using the 2 049 residents′ data of chronic metabolic disease in a community of Urumqi collected in May 2017, 1 822 subjects aged between 19-80 years with complete information were enrolled, their blood pressure, waist circumference, height, weight, body mass index were measured and recorded. Using oral glucose tolerance test to measure fasting and 2 h after meal plasma glucose, uric acid, HbA 1C, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C) levels were all tested. Results:(1)There were 363 (19.9%), 1 349 (74.0%), and 110 (6.1%) respondents with sleep time≤6.0, 6.1 to 8.0, and>8.0 h/d, respectively. There were statistically significant differences in age, education, and family income in groups with different sleep time ( P<0.05), while their gender, smoking status, and exercise status were not statistically significant ( P>0.05). The rates of overweight, obesity, abdominal obesity, high uric acid, and hypertension in people with different sleep durations were statistically different ( P<0.01). The rates of the above indicators were higher in the group of sleep time≤6.0 h/d than the other two groups. (2) Differences in diastolic blood pressure, systolic blood pressure, body mass index, abdominal circumference, total cholesterol, and LDL-C levels were statistically significant among different sleep duration groups ( P<0.05). Further comparisons of the above indicators among three groups with different sleep durations were performed ( P<0.05). The levels of the above indicators in the sleep time≤6.0 h/d group were higher than those in the other two groups. There were no significant differences in fasting blood glucose, glycated hemoglobin, uric acid, triglyceride, and HDL-C among the three groups. (3) Multivariate logistic regression analysis showed that groups whether or not adjusted of age, family income, and education level, sleep time≤6.0 h/d was related to abdominal obesity, and sleep time≤6.0 h/d was be a risk factor for abdominal obesity [Unadjusted: OR=1.48(95% CI1.04-2.08); Adjusted: OR=1.65(95% CI1.18-2.32; P<0.05]. Conclusion:Sleep time ≤6.0 h/d is associated with abdominal obesity, and sleep time≤6.0 h/d may be a risk factor for abdominal obesity.
ABSTRACT
Objective:Based on the previous epidemiological investigation of hyperparathyroxinemia in Urumqi community, a follow-up study was conducted to understand the changes of serum parathyroid hormone (PTH) level and clinical characteristics of residents with PTH.Methods:In the previous study (2013), an epidemiological cross-sectional study of hyperparathyroxinemia was conducted on 1 473 residents of the resident community, and 180 people with hyperparathyroxinemia were found. The serum PTH, parathyroid related laboratory indexes and vitamin D were observed in high PTH population of different genders.Results:According to the inclusion criteria, 159 patients with high PTH were included in the study. The total follow-up rate was 88.3% (159/180), including 24 males (15.09%) and 135 females (84.91%). The serum PTH level in the follow-up population was 68.60 (47.85-98.80)pg/ml, which was significantly different from that in the first visit ( P<0.01). There was no significant difference in serum PTH levels between men and women ( P>0.05). The levels of serum 25(OH)D, calcium, phosphorus, magnesium, creatinine, albumin and alkaline phosphatase in the follow-up population had no significant changes compared with the first visit population (all P>0.05); After stratified by sex, the serum creatinine level of men with high PTH was significantly higher than that of women ( P<0.01), and there was no significant difference in other PTH related laboratory indexes ( P>0.05); Although the vitamin D level was still deficient (<20 ng/ml), the proportion of people with sufficient vitamin D was significantly higher than that at the first visit. Conclusions:25(OH) D deficiency was still common in the follow-up population, but the vitamin D level of the residents with PTH was significantly improved and the serum PTH level was significantly lower than that in the first visit.
ABSTRACT
Objective:To investigate the correlation of multiple single nucleotide polymorphisms(SNPs)of thyroid peroxidase(TPO)and thyroglobulin(Tg)genes with Hashimoto′s thyroiditis(HT).Methods:Based on the gene mutation sites obtained from the second-generation sequencing of the target region of the previous autoimmune thyroid disease cases in our research group, the representative sites were selected for confirming in the expanded samples. A total of 301 Uyghur patients with HT and 383 controls were selected to determine the genotypes of representative SNPs(rs4927631, rs2071400, rs2071403, rs2403883, rs4236899, rs4736434, rs180195)using MassArry Sequenom platform. Correlation analysis and linkage analysis were performed with SPSS 21.0 software.Results:(1)The SNP rs4927631 gene frequency and genotype of TPO gene were significantly different between the case and control groups. The SNP rs2071403 gene frequency of TPO gene revealed statistically different between the case and control groups.(2)With analysis under different genetic models, the rs4927631 and rs2071403 of TPO gene were associated with HT under the additive model(AA/GG)and dominant model( P<0.05). The rs180195 of Tg gene was associated with HT in a recessive model( P<0.05). (3)All subjects were grouped according to the dominant genotype(AA+ GA)and recessive genotype(GG)of the TPO gene rs2071403, and mean age, gender distribution, proportion of those with higher TSH, and lower FT 4 were compared between two groups. Only thyroid peroxidase antibody(TPOAb) level displayed a statistical difference( P<0.05). This was the case for the patients with HT after grouped according to the above method( P<0.05). Conclusion:The rs4927631 and rs2071403 loci of TPO gene are associated with the pathogenesis of HT in Xinjiang Uygur.
ABSTRACT
Objective:To explore the correlation between rs231775 polymorphism of cytotoxic T lymphocyte-associated antigen 4 (CTLA4) gene and autoimmune thyroid disease (AITD) of Uygur in Xinjiang Uygur Autonomous Region.Methods:A total of 382 Uygur patients with AITD [including 328 Hashimoto's thyroiditis (HT) patients and 54 Graves' disease (GD) patients] diagnosed in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2017 to December 2018 were selected as the case group, and 383 Uygur health physical examiners in the same period were selected as the control group. The whole blood genomic DNA of the study subjects was extracted, and the Sequenom-mass spectrometry analysis platform was used to determine the genotyping of CTLA4 gene single nucleotide polymorphism (SNP) locus rs231775 and analyze the genetic model, and the correlation between rs231775 polymorphism and AITD under different genetic models was compared. The logistic regression analysis model was used to analyze the influencing factors of AITD. And the thyroid function index of different genotype population was compared.Results:In the case group and the control group, the differences of CTLA4 gene rs231775 alleles (A: 41.88%, 49.35%; G: 58.12%, 50.65%) and genotype frequencies (AA: 17.80%, 23.24%; AG: 48.17%, 52.22%; GG: 34.03%, 24.54%) were statistically significant (χ 2=8.586, 9.260, P < 0.05). Compared with the control group, the genotype frequency of rs231775 in HT group, the alleles and genotype frequencies of rs231775 in GD group were significantly different (χ 2=5.997, 11.130, 10.210, P < 0.05). Under the additive and dominant models, the CTLA4 gene rs231775 was correlated with AITD [odds ratio ( OR)=0.67, 0.55, 0.63] and HT ( OR=0.69, 0.62, 0.67, P < 0.05); and correlated with GD under the additive, dominant and recessive genetic models ( OR=0.53, 0.23, 0.44, 0.34, P < 0.05). The logistic regression analysis showed that genotype, gender, age, thyroid stimulating hormone (TSH) and free thyroxine (FT 4) were independent influencing factors of AITD ( P < 0.05). Among all the subjects, the level of thyroglobulin antibody(TgAb) in the population with the recessive genotype (GG) at the rs231775 of the CTLA4 gene was higher than that in the dominant genotype (AA+AG) population ( P < 0.05). Conclusion:The CTLA4 gene rs231775 polymorphism is significantly related to AITD of Uygur in Xinjiang Uygur Autonomous Region, and the level of TgAb in GG genotype is higher than that in other genotypes.
ABSTRACT
Objective:To observe the dynamic changes of thyroid hormone levels and thyroid autoimmune antibodies in pregnant women in Xinjiang Uygur Autonomous Region during pregnancy, and to investigate the significance of repeated screening of thyroid function in different gestational ages.Methods:A retrospective study was carried out of pregnant women who completed thyroid function screening in Clinic, People's Hospital of Xinjiang Uygur Autonomous Region from January 2015 to December 2017, and the test results of thyroid stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), thyroid peroxidase antibody (TPOAb), and anti-thyroglobulin antibody (TGAb) were collected and analyzed of their changes during pregnancy. Pregnant women were divided into 2 different gestational age groups by the age limit of 30, the changes of thyroid dysfunction rate with pregnancy were analyzed, and the clinical significance of repeated screening in different pregnancy stages was discussed. Results:Changes of thyroid-related indicators with pregnancy: first, second, and third trimesters were 404,725, and 767 cases, respectively; TSH level in the third trimester (2.76 mU/L) was significantly higher than those in the first and second trimesters (2.55, 2.36 mU/L, P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the FT 4 and FT 3 levels decreased gradually with pregnancy ( P < 0.05); the positive rate of TPOAb was significantly higher in the first and second trimesters than that in the third trimester ( P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the positive rate of TGAb decreased gradually with pregnancy ( P < 0.05). Comparison of abnormal rate of TSH in different gestational ages: the first, second, and third trimesters were 352, 664, 735 cases, respectively; the abnormal rate of TSH in the overall study was statistically significant at different stages of pregnancy (χ 2=31.627, P < 0.05), the first trimester was significantly higher those in the second and third trimesters ( P < 0.05). In pregnant women aged ≥30 years old, the abnormal rate of TSH in the first trimester was significantly higher than those in the second and third trimesters ( P < 0.05); in pregnant women aged < 30 years old, the abnormal rate of TSH in the first trimester was significantly higher than that in the third trimester ( P < 0.05). There were no significant differences in the abnormal rate of TSH in the first, second, and third trimesters between the < 30 years old group and ≥30 years old group ( P > 0.05). Comparison of abnormal rate of FT 4 in different gestational ages: there were no significant differences in the FT 4 abnormal rate among different pregnancy groups in the overall, < 30, ≥30 years old groups (P > 0.05). In early pregnancy, the abnormal rate of FT 4 in the ≥30 years old group was higher than that in the < 30 years old group ( P < 0.05); in second and third trimesters, there were no significant differences between the two age groups ( P > 0.05). Conclusions:Screening for thyroid function in the first trimester of pregnancy is important for women of different ages. Except for women with abnormal thyroid function who have not been treated during the first trimester, the rest may not need to be screened again. Pregnant women aged ≥30 years old may have a higher risk of thyroid dysfunction than those < 30 years old.
ABSTRACT
The clinical data of a patient with non-classical 21-hydroxylase deficiency ( 21-OHD) were retrospectively analyzed. The CYP21A2 gene analysis was performed on the patient and his family members by PCR-DNA direct sequencing. It was found that the proband had a heterozygous mutation [ point mutation:p.Ile173Asn, p. ( Ile237Asn, Val238Glu, Met240Lys ), p. Val282Leu, p. Gln319Ter, p. Arg357Trp, insertion mutation: p.Leu308Phefs?6, deletion/insert mutation: p. Arg484Profs]. Among the members of the family, the patient's eldest sister and three paternal members all carried the p.Val282Leu heterozygous mutation, and the patient's second sister and two maternal members carried the same p. Val282Leu homozygous mutation and other compound heterozygous mutations just as the proband. The proband presented a non-classical phenotype with ultimately normal height and fertility. It is suggested that the potential phenotype of the disease is related to the residual activity of its allele, and there exists a good genotype-phenotype correlation.
ABSTRACT
Objective The mechanism of apoptosis induced by polyphenyl propenoid-polysaccharide complex(PPC)in hu-man breast cancer MCF-7 cells was studied. Methods MCF-7 cells were cultured with different concentrations of PPC for differ-ent time. The effects of PPC on proliferation and apoptosis were detected in MCF-7 cells by MTT assay,fluorescent staining,apopto-sis detection kit,DNA gel electrophoresis and Western blot. Results PPC induced apoptosis in MCF-7 cells. When apoptosis oc-curred,the enzyme activities of caspase-3 and-9 were increased,and the expression of pro-caspase-3 protein was decreased. Caspase-3 inhibitor(z-DEVE-fmk)could partially inhibit PPC-induced apoptosis and inhibit activation of caspase-3 precursor enzyme. Conclusion PPC induces apoptosis of MCF-7 cells by activating caspase family.
ABSTRACT
Objective To establish a reference range for specific thyroid function during pregnancy and to explore the influencing factors of hypothyroxinemia during pregnancy.Methods A retrospective analysis of 2 996 cases of thyroid function in the pregnant women who were with single pregnancy and without thyroid diseases and family history of those diseases.Results (1) Establish a unified reference range for specific thyroid function during pregnancy;the early,middle,and late trimesters thyrotropin (TSH) ranges were 0.02-6.39,0.16-6.23,0.64-6.59 mU/L,respectively,while free thyroxine (FT4) ranges were 11.32-23.00,9.39-18.92,8.54-16.73 pmol/L respectively.The specific reference ranges of Han and Uygur pregnant women were established separately.There was no difference in the detection rates of various thyroid diseases when using their respective reference ranges and the unified reference range of the hospital (P ＞ 0.05).(2) The detection rate of various thyroid diseases (except subclinical hyperthyroidism) of our subjects with China guideline reference range was significantly higher than the reference range with the hospital (P＜0.05).(3) The detection rates of hypothyroxinemia in all pregnant women with FT4 cut points of P2.5 and P5 were 4.3％ and 7.4％,respectively,of which the Han population was 4.3％ and 7.1％,respectively,and the Uygur population was 4.3％ and 7.9％,respectively.(4) Comparing the mean age,gestational age,median urine iodine,and thyroid antibody positive rate between the hypothyroxinemia group and the control group,only the mean age and gestational age were different (P＜0.05);Logistic binary regression analysis showed that age was the risk factor for hypothyroxinemia during pregnancy (OR =1.035,95％ CI 1.006-1.066,P ＜ 0.05).Conclusions The Han and Uygur pregnant women in this area both can use the thyroid reference range of our hospital during pregnancy.The establishment of thyroid reference range may avoid over-diagnosis of thyroid disease during pregnancy.Age is a possible influencing factor of hypothyroxinemia during pregnancy.

ABSTRACT
Objective To investigate the status of increased blood parathyroid hormone(PTH)level among community residents in Urumqi,and to analyze its correlation with the metabolic parameters including serum Ca and P levels. Methods In May 2013,a cross-sectional survey was conducted,when 1 473 permanent residents in Urumqi, including 844 Han and 629 Uyghurs,were selected by cluster random sampling. PTH and 25-OH vitamin D[25(OH)D] levels were detected by chemiluminescence. Blood Ca, P, Mg, albumin, and creatinine (Cr) were also measured. Based on serum 25(OH)D level,the residents were divided into vitamin D deficiency(<20 ng/ml), vitamin D insufficiency(≥20 and<30 ng/ml),and vitamin D sufficiency(≥30 ng/ml)groups. According to the PTH level,the residents were divided into PTH<65 pg/ml group and PTH≥65 pg/ml group. The metabolic parameters including Ca and P were compared among different ethnic groups. Results In the surveyed population,the rate of increased blood PTH was 12.22%,being higher in females than that in males(13.82% vs 8.45%,P=0.004)and higher in Han Chinese than that in Uyghurs(19.87% vs 6.52%,P<0.01). The proportions of residents with vitamin D sufficiency,insufficiency and deficiency were 3.34%,9.06%,and 87.60% in Uyghurs,and 10.43%,29.98%, and 59.60% in Han,respectively. The rate of 25(OH)D deficiency was significantly higher in Uyghurs than that in Han(P<0.01),especially higher in female Uyghurs(91.43%). In vitamin D deficiency group,the rate of increased serum PTH was significantly increased,higher in Uyghurs than that in Hans(22.14% vs 6.56%,P<0.01),which revealed a negative correlation with 25(OH)D(r=-0.251, P< 0.01). Conclusion 25(OH)D deficiency is prevalent among the community population in Urumqi, with ethnic differences in serum PTH level and the rate of increased blood PTH,which might be associated with vitamin D deficiency.

ABSTRACT
OBJECTIVE:To compare the effects of repeated subcutaneous insulin administration vs. insulin pump continuous subcutaneous administration on related indexes of advanced age patients with gestational diabetes mellitus(GDM). METHODS:Inretrospective study,120 advanced age patients with GDM were randomly divided into group A(60 cases)and group B(60 cases). Group A was given Insulin aspart injection with initial dose of 0.5 U/(kg·d)subcutaneously before meal,adjusted according to fast-ing blood glucose(FPG)and postprandial 2 h blood glucose(2 hPG),and then given Isophane protamine biosynthetic human insu-lin injection with initial dose of 0.5 U/(kg·d)subcutaneously at bedtime,adjusted according to FPG and 2 hPG. Group B was giv-en Insulin aspart injection with initial dose of 0.5 U/(kg·d)added into insulin pump using 40% of total daily insulin as basic pump,increasing to 60% of total daily insulin if blood glucose control was poor,adjusted according to FPG and 2 hPG. Treatment course of 2 groups lasted for 4 weeks. The time of blood glucose reaching target,the amount of insulin were observed in 2 groups, and the levels of FPG,2 hPG,HbA1c,Hcy and Cys-C before and after treatment,the occurrence of patients and neonates compli-cations. RESULTS:The time of blood glucose reaching standard in group B was significantly shorter than group A;the amount of insulin,the incidence of hypoglycemia,premature birth,excessive amniotic fluid and gestational hypertension in group B were sig-nificantly lower than group A,with statistical significance(P0.05). After treatment,the levels of FPG,2 hPG,HbA1c,Hcy and Cys-C in 2 groups were significantly lower than before treatment,and the group B was significantly lower than the group A, with statistical significance(P<0.05). CONCLUSIONS:The insulin pump continuous subcutaneous administration is significantly better than repeated subcutaneous insulin administration in respects of controlling glucose level,reducing the amount of insulin,the levels of Cys-C and Hcy,maternal and neonatal complications.

Methods:A total of 100 postoperative patients of early cervical squamous cell carcinoma treated in Affiliated Tumor Hospital of Xinjiang Medical University and Affiliated Tumor Hospital of Sun Yat-sen University from March to September 2013 were enrolled in our study. The prognostic factors for these patients were analyzed. After being subjected to differ-ent postoperative radiotherapy techniques, the efficacy and complications of the techniques were assessed for patients, including 50 cases of conventional radiotherapy (CRT) and 50 cases of image-guided radiotherapy (IGRT). Results:The 3-year overall survival rate was 89%, and the 3-year disease-free survival rate was 78%. The 3-year overall survival rates of the CRT and IGRT groups were 78.57%and 89.06%, respectively. The difference between these rates was statistically significant (P=0.034). The 3-year survival rates of the CRT and IGRT groups were 66.67%and 87.36%, respectively. The difference was statistically significant (P=0.042). The incidence of ear-ly and late complications in the CRT group was higher than that in IGRT group, and the difference of P<0.05 was statistically significant. Multivariate analysis showed that postoperative radiotherapy, parametrial invasion, lymph node metastasis, lymphovascular space in-vasion, perineural invasion, and deep stromal invasion were the independent risk factors for the prognosis of patients with early stage cervical squamous cell carcinoma. Conclusion:Early prognosis of cervical squamous cell carcinoma results from the interaction of mul-tiple factors. The 3-year survival rate of the IGRT group was significantly better than that of the CRT group in the early stage of cervical squamous cell carcinoma. IGRT alleviates acute and chronic toxicities and helps improve the quality of life of patients.
ABSTRACT
Objective To evaluate iodine nutrition status and vitamin D level in hyperthyroidism patients and explore their impacts on the pathogenesis of hyperthyroidism.Methods Totally 116 inpatients of hyperthyroidism were tested for serum thyroid function,urine iodine and serum 25-OH-D.Median and component ratio of urine iodine and 25-OH-D were used to evaluate nutrition status.Results The median of urine iodine was 224.9 μg/L,while the component ratio of iodine excessive-intake was 59.48％ (12.93％ in excessive group and 46.55％ in sufficient group).The median of vitamin D was 7.19 ng/ml while as deficiency group accounted for 93.2％ in hyperthyroidism patients.Conclusions Attention should be paid to excessive intake iodine in hyperthyroidism patients.Vitamin D supplementation is important for treating hyperthyroidism and maintaining the health of skeleton and muscle.
ABSTRACT
Objective To understand the vitamin D status and its possible ethnic differences among Uygur and Han women of childbearing age in a community of Urumqi.Methods Based on the data of 2 080 patients with thyroid disease in a community of Urumqi,which were collected in May 2013,we selected the complete information of 652 Uygur and Han women of childbearing age (between 18-45 years),which included 367 Uygur women [average age (35.14± 6.91) years] and 285 Han women [average age (35.52± 7.10) years].The basic data of height,weight,and waist circumference were recorded.The serum level of 25-hydroxyl vitamin D [25(OH) D] was detected by chemiluminescence method.Results The serum 25(OH) D levels of Uygur and Han were (11.51±6.31) μg/L and (16.43±6.43) μg/L,respectively.The 25(OH)D level in Uygur women was significantly lower than that of Han women (t =-9.800,P＜0.001).The constituent ratio of vitamin D status was significantly different between Uygur and Han women (vitamin D severe deficiency:47.4％ in Uygur women and 12.3％ in Han women),deficiency (44.7％ in Uygur women and 64.6％ in Han women),insufficiency 5.7％ in Uygur women and 17.9％ in Han women),sufficiency (2.2％ in Uygur women and 5.2％ in Han women) (x2 =99.486,P＜0.001).Conclusion Serum 25 (OH) D deficiency is common in Uygur and Han women of childbearing age in Urumqi,especially among Uygur women.
ABSTRACT
Objective To investigate the clinical application value of multi-directional liver acquisition with volume acceleration (LAVA)imaging in diagnosing adult intussusception.Methods Nine cases with adult intussusception confirmed by multi-directional LAVA imaging and operation were included in the study.The MRI manifestations were analyzed retrospectively.Results Of the 9 cases,there were 4 cases of small intestine intussusception,1 case of ileocecal intussusception,3 cases of ileocecum intussusception and 1 case of colon intussusception.MRI features showed"target"sign in 9 cases,"bowel within bowel"sign in 4 cases,"kidney-shaped"mass in 8 cases,double"target"sign in 3 cases,"8"character sign in 3 cases,mesenteric lymph node tumescence in 1 case and ileus in 1 case.Conclusion The multi-directional LAVA imaging can help to show the various features of intussusceptions.
