Objective:To study the urinary iodine levels of children in Jiangxi Province and provide a basis for prevention and treatment of iodine deficiency disorders and scientific iodine supplementation.Methods:From March to July in 2022, a systematic sampling method was used in 99 counties (cities, districts, abbreviated as counties) in Jiangxi Province. One township (street) was selected from each county in five directions: east, west, south, north and middle. One primary school was selected from each township (street), and 40 non boarding children aged 8 - 10 (half male and half female) were selected from each primary school. One random urine sample was collected to test urinary iodine, and the distribution of urinary iodine in different regions, genders, and ages were compared.Results:A total of 19 842 urine samples were collected from children, with a median urinary iodine level of 181.90 μg/L. The median urinary iodine levels of children in different cities ( H = 1 014.05, P < 0.001), genders ( Z = 6.44, P < 0.001) and ages groups ( H = 29.82, P < 0.001) were compared, and the differences were statistically significant. Conclusion:The urinary iodine level of children in Jiangxi Province is at an appropriate level, but the distribution of urinary iodine is uneven among different regions, genders, and ages, indicating that scientific and precise iodine supplementation is necessary for the prevention and treatment of iodine deficiency disorders.

Objective:To investigate the effect of behavioral lifestyle on the CT values of urinary tract stones, as well as the relationship between behavioral lifestyle and the therapeutic effect of extracorporeal shock wave lithotripsy (ESWL).Methods:A total of 265 patients with urinary tract stones who underwent ESWL treatment at Affiliated Hospital of Jining Medical University from January 2019 to June 2023 were selected. According to the CT values of the stones, the subjects were divided into high CT value group (CT value > 1 000 HU, n=106) and low CT value group (CT value ≤ 1 000 HU, n=159). A retrospective survey was conducted to assess the patients' behavioral lifestyles, and general data, CT values, number of lithotripsy sessions, lithotripsy time, lithotripsy efficiency, and incidence of complications were compared between the two groups. SPSS 22.0 software was used for statistical analysis. The χ2 test and t-test were used for group comparisons, and Pearson correlation analysis was used to examine the relationship between stone CT values and different behavioral lifestyles. Results:The high CT value group had lower average daily water intake((1 242±347)mL vs (1 784±376)mL), average daily fresh fruit intake((135±43)g vs (196±51)g), and average daily exercise time((18±12)min vs (32±14)min) compared with the low CT value group( t=-11.850, -9.926, -8.434, all P<0.01). In contrast, the high CT value group had higher average daily salt intake((8.3±2.2)g vs (6.5±1.7)g) and average daily animal protein intake ((72±18)g vs (54±16)g) compared with the low CT value group ( t=7.495, 8.531, both P<0.01). The high CT value group required more lithotripsy sessions and longer lithotripsy time than the low CT value group ( t=6.192, 7.507, both P<0.05), while lithotripsy efficiency was lower than the low CT value group ( χ2=33.181, P<0.01). The incidence of complications was higher in the high CT value group compared to the low CT value group ( χ2=3.915, P=0.048), with statistically significant differences. Conclusion:Appropriate water intake, diet, and exercise habits are beneficial in reducing stone CT values, improving the efficacy of ESWL treatment, and decreasing the incidence of complications.

Objective To investigate the feasibility,safety,and effectiveness of ultrasound-guided microwave ablation in the treatment of multifocal T1N0M0 papillary thyroid carcinoma(PTC).Methods A total of 68 patients with multifocal T1N0M0(≤ 3 lesions)PTC,whose diagnosis was confirmed at authors'hospital from January 2019 to January 2022,were randomly included as the study subjects.The maximum diameter of tumor was ≤2 cm.Ultrasound-guided microwave ablation was carried out in all patients.The patients were followed up until April 2023,with a median time of 30 months.The follow-up examinations included conventional ultrasound,contrast-enhanced ultrasound,thyroid function,and necessary fine needle aspiration cytology(FNA).Results The 68 patients were divided into T1a group(n=52)and T1b group(n=16).The ablation time in Tib group was significantly longer than that in T1a group,and the maximum diameter of tumor in T1b group was significantly larger than that in T1a group,the differences were statistically significant(P＜0.05).All 68 patients successfully completed the surgery and were recovered at discharge with no obvious complications.Contrast-enhanced ultrasound imaging revealed that the ablated lymph nodes showed no enhancement.Post-ablation one-,3-and 6-month maximum diameters and volumes of the tumor were significantly larger than their pre-ablation values(P＜0.05).Post-ablation 12-,18-and 24-month maximum diameters and volumes of the tumor were gradually decreased(P＜0.05).No tumor progression or recurrence was observed during follow-up period.Thyroid function including thyroglobulin,total thyroxine,and thyrotropin,which were determined before ablation and at the last follow-up visit,showed no significant changes(P＞0.05).Conclusion For the treatment of T1N0M0 PTC,ultrasound-guided microwave ablation has excellent clinical feasibility,safety,and effectiveness.(J Intervent Radiol,2024,33:495-499)

Objective:To analyze the genetic etiology of spontaneous abortion in the first trimester.Methods:This study was a retrospective analysis. The subjects were 815 pregnant women who voluntarily underwent genetic testing of pregnancy miscarriage embryos due to spontaneous abortion or embryonic development arrest in six to thirteen gestational weeks from January 2021 to December 2022. High-throughput sequencing technology was used to detect the abortion tissue, and the results were analyzed by bioinformatics method. Statistical analysis was conducted using the Chi-square test. Results:(1) Chromosomal abnormalities were detected in 525 out of 815 cases (64.4%), including 479 cases (91.2%) of numerical abnormalities (421 cases of aneuploidy and 58 cases of triploidy), 44 cases (8.4%) of structural abnormalities (copy number variation, CNV), and two cases (0.4%) of uniparental disomy. (2) Among the numerical abnormalities, aneuploidy was the most common (87.9%, 421/479), involving all chromosomes except chromosome 1. Trisomy 16 had the highest frequency (17.5%, 84/479), followed by monosomy X (13.4%, 64/479) and trisomy 22 (11.3%, 54/479). Multiple chromosomal abnormalities were present in 27 cases (5.6%). Among the nine cases of autosomal monosomy, there were seven cases of monosomy 21, and one case each of monosomy 18 and monosomy 4. (3) Among the 44 cases of structural abnormalities, 62 pathogenic or possible pathogenic CNVs were identified, with fragment lengths ranging from 1.08 Mb to 103.81 Mb, averaging 19.58 Mb.Chromosome 8 was the most involved in CNV, with 16 cases (25.8%, 16/62), followed by chromosome 4 and 18 with six cases each (9.7%,6/62).Of the 62 CNVs, ten (16.1%) were ≤5 Mb in size, including three cases of microdeletion syndromes.(4) For embryos without autosomal numerical abnormalities indicated by low-depth copy number variation sequencing (CNV-seq) results, quantitative fluorescence polymerase chain reaction verification was performed, detecting two cases of complete uniparental disomy, both of which were paternal uniparental disomy and identified as complete hydatidiform moles. (5) Among the 44 cases where CNV-seq results indicated the presence of CNV in the embryos, 32 cases opted for peripheral blood karyotype analysis, with nine cases (28.1%) identified as carriers of balanced chromosomal translocations in one of the parents. These nine samples all involved variations in two chromosomes, both located at the chromosome ends. For CNV with fragment sizes≤5 Mb, two cases underwent CytoScan 750K array testing, and the chip results were consistent with the CNV-seq sequencing results. (6) Among the 32 couples who underwent peripheral blood karyotype analysis, nine underwent fluorescence in situ hybridization (FISH) testing for chromosomal regions, with six cases showing normal results and three showing abnormalities. The FISH abnormal regions were consistent with the karyotype results. (7) The rate of chromosomal abnormalities in embryos from pregnant women aged≥35 years, as well as the rate of numerical chromosomal abnormalities, were significantly higher than in those aged <35 years [75.8% (182/240) vs. 59.6% (343/575), χ2=23.37; 73.3% (176/240) vs. 53.2% (306/575), χ2=19.34; both P<0.001]. There was no statistically significant difference in the rate of structural chromosomal abnormalities between the two groups. Conclusion:Abnormal chromosome number is the main cause of spontaneous abortion in the first trimester, which is more obvious in pregnant women with abortion age≥35 years. CNV-seq may be more suitable for the detection of spontaneously aborted embryos in the first trimester.

[Objective]To investigate the osteoprotective effect and molecular mechanism of Cnidium monnieri on kidney Yang deficiency-induced osteoporosis in rats.[Methods]SD rats were divided into normal,model,Cnidium monnieri extract and osthole groups.The rats except for normal group were given hydrocortisone subcutaneously every day.The rats were given Cnidium Monnieri extract,osthole or vehicle intragastric daily for 3 weeks.After anesthesia,rat femurs were collected.Tartrate phosphatase staining,transforming growth faction-β(TGF-β)immunohistochemical staining and bone mineral density detection were performed on the left femur,while Real-time quantitative polymerase chain reaction and western blot detection of target gene and protein expression were performed on the right femur.[Results]Hydrocortisone has been shown to significantly enhance the differentiation and maturation of rat osteoclasts,while inhibiting the formation of osteoblasts.This results in a reduction in the formation of bone trabeculae and ultimately induces osteoporosis in rats with kidney-yang deficiency.The results of bioinformatics analysis suggested that TGF-β signaling pathway was the potential candidate target pathway for Cnidium monnieri.Cnidium monnieri extract and osthole significantly reduced the differentiation and maturation of osteoclasts,promoted the differentiation and maturation of osteoblasts,and ultimately inhibited the osteoporosis in rats induced by hydrocortisone.The extract of Cnidium monnieri and osthole significantly increased the downregulation of TGF-β gene induced by hydrocortisone in femur.[Conclusion]Cnidium monnieri and osthole can inhibit osteoporosis in kidneyYang deficiency rats through TGF-β signaling pathway.

ObjectiveTo evaluate the quality of Mori Cortex from different producing areas by the entropy weight-technique for order preference by similarity to an ideal solution（TOPSIS）， and to provide a new evaluation method for the quality control of Mori Cortex. MethodAccording to the five key indexes of color， thickness， texture， powdery and cortex remain， a subjective scoring table was designed to evaluate the appearance of Mori Cortex. High performance liquid chromatography（HPLC） was used to determine the fingerprint and the contents of multiple components（mulberroside A， chlorogenic acid， oxyresveratrol， mulberroside C， sanggenone D， sanggenone C， morusin）， and chemometrics was used to explore the differential components of Mori Cortex from different habitats. On this basis， TOPSIS was used to comprehensively evaluate the quality of Mori Cortex from different habitats， and SPSS 22.0 software was used to carry out bivariate correlation analysis between thickness and appearance color with contents of seven components of Mori Cortex. ResultThose with lighter color， thicker root bark， tougher texture， sufficient powder and less cortex remain scored higher， and the top five were all from Anhui. The established fingerprint and determination methods were stable and reliable. Partial least squares-discriminant analysis（PLS-DA） screened three components with the variable importance in the projection（VIP） value>1（mulberroside A， sanggenone D， sanggenone C）， which made an important contribution to the difference in the origin of Mori Cortex. Correlation analysis showed that there was a significantly positive correlation between mulberroside C with lightness value（L^*） and total chromaticity value（E^*ab） and mulberroside A with yellow-blue value（b^*）（P<0.05， P<0.01）， a significantly negative correlation between sanggenone C with b^* and between morusin with L^*（P<0.05， P<0.01）. And there was a significantly negative correlation between mulberroside A， chlorogenic acid， and morusin with thickness（P<0.01）， a clearly negative correlation between sanggenone D with thickness（P<0.05）， a significantly positive correlation between sanggenone C with thickness（P<0.01）. TOPSIS comprehensive scores showed that the samples from Anhui had a good score and ranked high. ConclusionThere are great differences in the quality of Mori Cortex from different habitats， and those with the close habitats show similar characteristics in appearance and component content， and lighter color and less cortex were positively correlated with the quality. Among them， the quality of Mori Cortex from Anhui is relatively good.

Objective: To understand the symptoms of depression and anxiety among rural returning adolescents and to analyze their association with physical activity related factors, so as to provide reference for interventions targeting depression and anxiety symtoms in the population. Methods: From April to June 2020, 3 495 middle school students were selected from 6 counties and districts of Shangrao City by random cluster stratified sampling sampling. The Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to evaluate the depressive and anxiety symptoms among middle school students. The International Physical Activity Questionnaire was used to assess their physical activity levels during the past week. Chi square test and Logistic regression analysis were used to determine the strength of the association between depression and anxiety symptoms and physical activity related factors in returning and non returning adolescents as well as the overall population. Results: Univariate analysis showed significant differences in the prevalence of depressive and anxiety symptoms between rural returning and non returning adolescents and the overall population in terms of "type of school" "family economic situation" "parental occupation" "number of sports classes per week" and "level of physical activity per week" ( χ 2=78.21, 16.56, 135.44, 107.75, 7.10, 8.62; 97.94, 24.26 , 124.07, 90.36, 9.60, 8.34, P <0.05). Multivariate regression analysis showed a correlation between the occurrence of depression and the number of sports classes per week for rural returning and non returning adolescents and the overall population (number of sports classes per week for non returning was 2 times, OR=1.22, 95%CI =1.01-1.49; returning adolescents for 1 time, OR=1.85, 95%CI =1.06-3.23; the overall population for 1 time, OR=1.34, 95%CI =1.01-1.77 and 2 times, OR=1.20, 95%CI =1.01-1.43, P <0.05). There was a correlation between anxiety symptoms and the number of sports classes per week for returning adolescents (number of sports classes per week for returning adolescents was 1 time, OR=2.10, 95%CI=1.21-3.63, P < 0.05 ). Conclusion A low frequency of weekly sports classes may be a risk factor for depressive or anxiety symptoms in rural and returning adolescents. Rural primary and secondary schools should appropriately increase the number of physical education courses or arrange sports extended classes to promote the development of adolescent mental health.

Objective : To investigate whether Mitochondria-targeted antioxidant peptide SS-31 can inhibit the ozone ( O3 ) -induced mice lung airway hyperresponsiveness and mucus hypersecretion． Methods : Eight-week C57BL /6 mice were randomized into four groups，including phosphate buffer saline (PBS) + Air group，SS-31 + Air group， PBS + O3 group and SS-31 + O3 group．C57BL /6 mice were injected intraperitoneally with SS-31 ( 10 mg / kg) one hour before ozone exposure ，and then single-exposed to ozone at a concentration of 5. 01 × 10 －6 mol / m3 for 3 hours．After 24 hours，airway hyperresponsiveness(AHR) and bronchoalveolar lavage fluid (BALF) cells numbers were measured．Lung tissue schiff periodic acid shiff (PAS) staining，malondialdehyde (MDA) ，inflammatory factors ( interleukin，IL ) -1 β , IL-6 ，IL-18 and monocyte chemoattractant protein-1 ( MCP-1 ) ) and mucin factor (MUC5B) were detected，and the protein expression levels of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) ，pro-Caspase 1 / Caspase 1 (p20) ，Gasdermin D ( GSDMD) and Cleaved GSDMD were determined by Western blot. Results: O3 exposure caused both mice lung airway hyperresponsiveness and mucus hypersecretion．However，SS-31 could inhibit the O3 -induced airway hyperresponsiveness and mucus secretion，reduce the levels of oxidative stress and inflammatory factor mRNA expression ，and downregulate the protein expression level of NLRP3 and the activated forms of Caspase 1 and GSDMD． Conclusion SS-31 could suppress O3 -induced mice airway hyperresponsiveness and mucus hypersecretion by inhibiting the NLRP3 / Caspase 1 / GSDMD signaling pathway.

Objective:To understand the incidence of post-traumatic stress disorder(PTSD) in fathers with premature infants and analyze the risk factors.Methods:Conveniently, the 203 fathers of premature infants in NICU of Affiliated Hospital of Jining Medical University of Shandong Province from May to August 2021 were selected as the subjects to fill in the general data questionnaire, Perinatal Post-traumatic stress disorder Questionnaire-Chinese edition (PPQ-C), Parents, Perception of Uncertainty Scale, Social Support Rating Scale, Simplified Coping Style Questionnaire. Logistic regression was used to analyze the risk factors of PTSD and establish a nomogram model. ROC curve was used to verify the discrimination ofthe model. Hosmer-Lemeshow goodness-of-fit test and Calibration Plot were used to verify the calibration.Results:PPQ-C total score of 203 fathers was 17.17 ± 8.77, 81 fathers, symptoms were positive and the incidence of PTSD was 39.90%(81/203). Logistic regression analysis showed college degree ( OR = 0.297, 95% CI 0.116 - 0.763, P<0.05), very low birth weight ( OR = 2.491, 95% CI 1.027 - 6.044, P<0.05), sense of disease uncertainty ( OR = 1.038, 95% CI 1.012 - 1.066, P<0.05), negative coping style ( OR = 1.871, 95% CI 1.127 - 3.108, P<0.05) were risk factors of PTSD in fathers with premature infants. The nomogram model was established basing on the results of the Logistic regression analysis, and the ROC curve proved (AUC = 0.751) the model having a good discrimination.The Hosmer-Lemeshow goodness-of-fit test ( P = 0.974) and the calibration plot demonstrated that the prediction values tends to coincide with the actual monitoring values. Conclusions:A higher incidence of PTSD was observed in fathers with hospitalized premature infant. It was related to education level, the infants′s birth weight, disease uncertainty and coping style. Therefore, the nurses should give information support and psychological guidance according to the individual situation of the infants′ father to reduce the incidence of PTSD.
