OBJECTIVE: To explore the relationship between lumbar degenerative spondylolisthesis and T2WI high signal in the interspinous ligament in MRI in order to improve the understanding of the signal changes of the interspinous ligament. METHODS: The clinical data of 43 patients with clinically diagnosed lumbar degenerative spondylolisthesis were collected from March 2018 to March 2020, there were 19 males and 24 females, aged 50 to 92 years with an average of 69 years old. Using picture archiving and communication systems (PACS) to access images and record the distribution and incidence of T2WI high signal in the interspinous ligament between the slipped and non-slipped segments. Using Spearman correlation analysis to explore the relationshipbetween the T2WI high signal of the interspinous ligament and the degree of lumbar spondylolisthesis. RESULTS: Except for 8 ligaments that were not included in the statistical results due to poor image quality, 43 patients with a total of 207 lumbar vertebrae and interspinous ligaments were included in the study. According to the Meyerding classification method, 43 patients had a total of 48 segments with spondylolisthesis, 41 segments in grade Ⅰ and 7 segments in grade Ⅱ. There were 30 cases of MRI T2WI high signal in the interspinous ligament corresponding to spondylolisthesis segment, including 3 cases on L CONCLUSION In patients with degenerative lumbar spondylolisthesis, the MRI T2WI hyperintensity is more common in the interspinous ligament. The occurrence of T2WI high signal is positively correlated with the degree of spondylolisthesis, which should be payed enough attention in imaging diagnosis.

Objective: To investigate the prevalence of Calodium hepaticum (C. hepaticum) in rodents and insectivores from Wuhan section of the Yangtze River in China, and to provide evidence for the prevention and treatment of hepatic Calodium infection. Methods: Rodents and insectivores were captured from three selected Yangtze River beaches using mousetraps. The three survey sites were divided into six areas according to natural conditions, with 60 mousetraps placed in each area. The liver lesions in the captured rodents were observed by the naked eye and the eggs in the liver tissue were observed by microscopic examination. Results: A total of 1 080 mousetraps were placed, and 1 075 mousetraps were retrieved, with the retrieve rate as 99.5%. A total of 101 Apodemus agrarius, 12 Rattus norvegicus, and 9 Crocidura attenuata were caught. The average density of rodents and insectivores was 10.5% and 0.8%, respectively. DNA of egg nodules from infected rodents showed 98% similarity with that of C. hepaticum 18S rRNA (LC425008.1). One Rattus norvegicus was infected with C. hepaticum, with an infection rate of 3.23% in the Erqi river beach; the other two beaches did not show the incidence of C. hepaticum. Conclusions: The monitoring of C. hepaticum in the Yangtze River beaches should be strengthened to reduce the risk of human C. hepaticum infection.

OBJECTIVETo investigate the risk factors for the development of congenital anal atresia in neonates.

METHODSA total of 70 neonates who were admitted to 17 hospitals in Foshan, China from January 2011 to December 2014 were enrolled as case group, and another 70 neonates who were hospitalized during the same period and had no anal atresia or other severe deformities were enrolled as control group. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the development of congenital anal atresia.

RESULTSThe univariate analysis revealed that the age of mothers, presence of oral administration of folic acid, infection during early pregnancy, and polyhydramnios, and sex of neonates showed significant differences between the case and control groups (P<0.05). The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086).

CONCLUSIONSInfection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.

Objective: To investigate the expression of miR-218 and its clinical significance in osteosarcoma tissues and explore its effect on proliferation and apoptosis in osteosarcoma cells. Methods: miR-218 expression was detected in 76 samples of surgically resected osteosarcoma and matched normal tumor-adjacent tissues using quantitative reverse transcription polymerase chain reaction (qRT-PCR). MiR-218 was over-expressed by exogenous miR-218 plasmids in Saos-2 cells, and then BrdU cell proliferation assay and flow cytometry were used to determine cell proliferation and apoptosis. Results: The expression of miR-218 in osteosarcoma tissues was significantly lower than those in normal tumor-adjacent tissues (t=8.735, P<0.001). MiR-218 expression in tumor tissues was significantly correlated with tumor size (χ

OBJECTIVETo evaluate the status of diffuse goiter of population in Zhejiang Province and to analyze the relevant influencing factors.

METHODSA total of 18 188 subjects were recruited in the cross sectional survey, by multistage stratified cluster random sampling method. B ultrasound measurement were carried among the subjects to detect the thyroid volume, and the basic information and life styles were interviewed by questionnaires. Then, we analyzed the distribution and its influencing factors of diffuse goiter.

RESULTSThe ratio of diffuse goiter among the surveyed population was 2.2% (403/18 188), the difference showed statistical significance (χ(2) = 267.11, P < 0.05). The ratio among the group aged 6-7 years old and 8-10 years old was comparatively high, separately 10.3% (27/262) and 9.8% (51/519). The ratio among women (2.9%, 305/10 470) was higher than it among men (1.3%, 97/7672) (χ(2) = 55.55, P < 0.05). The residents from inland areas had the highest prevalence (3.2%, 138/4374), followed by residents from sub-coastal areas (2.0%, 131/6411), coastal areas minimum (1.8%, 138/4374) (χ(2) = 24.31, P < 0.05). The content of water iodine and salt iodine among people with symptoms of goiter had statistical difference with it among ordinary population (water iodine:χ(2) = 4.95, P = 0.026; salt iodine: χ(2) = 11.03, P < 0.01). The median(quartile) of water iodine in ordinary population was 2.41 (1.96-6.15) µg/L and among people with symptoms of goiter was 1.88 (1.49-5.15) µg/L. The median(quartile) of salt iodine in ordinary population was 30.18 (24.69-32.65) mg/kg and among people with symptoms of goiter was 29.1 (24.70-31.95) mg/kg. The influential factors of goiter were as follows: the family income, the education degree, the job and profession status, the diet character, the habitual sea food consumption, the alcohol intake status (χ(2) were separately 8.08, 37.85, 98.78, 68.69, 10.91, 12.21, 26.94, P < 0.05). Multi-factor analysis showed the results as follows: female (OR = 0.27 95%CI:0.18-0.39), school students (OR = 8.05, 95%CI:3.87-16.73), vegetarian (OR = 1.60, 95%CI:1.15-2.22) took a higher risk of getting pathogenic goiter; while the group of those who had university degree or above (OR = 0.84, 95%CI: 0.73-0.97), ate sea food frequently (OR = 0.62, 95%CI:0.44-0.88) took a lower risk.

CONCLUSIONSThe ratio of diffuse goiter in the group aged among 6-7 years old and 8-10 years old was comparatively high. The ratio was influenced by many factors.

OBJECTIVETo evaluate the iodine nutrition level of population in Zhejiang province and to analyze the relevant influencing factors from 2009 to 2011.

METHODSFrom October 2009 to October 2011, a total of 19 517 subjects were recruited in this cross sectional survey, by multistage stratified cluster random sampling method. The subjects were all living over three years in Zhejiang province. The basic information and life styles were interviewed by questionnaires; and the samples of drinking water, edible salt and urines were separately collected from the subjects to test the content of iodine. In total, 16 228 subjects answered the questionnaire, and 265 samples of drinking water, 7811 samples of edible salt and 19 517 samples of urine were collected. Then, we analyzed the distribution of iodine in water, edible salt and urine samples, as well as the relevance.

RESULTSThe median (25% - 75% percentile) of water iodine was 2.42 (1.17 - 6.28) µg/L in drinking water among Zhejiang residents; while separately 2.79 (1.60 - 6.87) µg/L in city and 2.04 (1.03 - 5.29) µg/L in country side (Z = 2.07, P < 0.05). The figures turned out to be 2.17 (1.22 - 5.73) µg/L, 2.77 (1.88 - 6.87) µg/L, and 1.40 (0.77 - 5.65) µg/L, respectively, in coastal areas, coastal periphery areas and inland areas (χ(2) = 11.16, P < 0.05). The median (25% - 75% percentile) of salt iodine was 28.80 (22.93 - 32.40) mg/kg; while separately 29.00 (24.50 - 32.60) mg/kg and 28.50 (13.90 - 32.29) mg/kg in city and country side (Z = 6.32, P < 0.05). The figures turned out to be 25.19 (0.00 - 30.20) mg/kg, 29.00 (26.60 - 31.70) mg/kg and 32.40 (28.94 - 36.30) mg/kg, respectively, in coastal areas, coastal periphery areas and inland areas (χ(2) = 1581.62, P < 0.05). The coverage rate of iodized salt was 79.54% (6213/7811) in all province. The urinary iodine median was 160.74(97.20 - 247.00) µg/L, while the urinary iodine median in pregnant women was 137.99 (82.40 - 215.30) µg/L, lower than the recommended optimal levels, which was 150 - 249 µg/L. The figures turned out to be 153.45(92.00 - 237.50) µg/L in city and 168.00 (102.18 - 257.00) µg/L in country side (Z = -9.25, P < 0.05); while in coastal, coastal periphery place and inland areas, the median were separately 156.00 (94.29 - 242.80) µg/L, 150.14 (94.70 - 227.00) µg/L and 187.70 (109.00 - 276.80) µg/L (χ(2) = 194.12, P < 0.05). The analysis of relevance between urine iodine, water iodine and iodized salt showed that the urine iodine would increase as long as the iodized salt increased; and the difference had statistical significance (χ(2) = 440.88, P < 0.01). And there were no relevance between urine iodine level and the water iodine level (χ(2)cmh = 0.57, P = 0.45). The analysis of the influencing factors showed that education background (χ(2) = 14.17, P < 0.05), different styles of career (χ(2) = 16.15, P < 0.01) and diet habits (χ(2) = 108.63, P < 0.01) could influence the level of urine iodine.

CONCLUSIONIodine was deficient in Zhejiang province. The nutrition level of iodine was fine in Zhejiang in 2009, however, the coverage rate of iodine was commonly low in coastal areas, especially the pregnant women suffered from iodine deficiency. In our study, the factors influencing the urine iodine level included iodized salt, age, education background and diet habits.
