Objective: To analyze the morbidity and mortality trends of thyroid cancer in China from 1990 to 2019, explore the causes of the trends, and predict morbidity and mortality in the future. Methods: The morbidity and mortality data of thyroid cancer in China from 1990 to 2019 were collected from the 2019 Global Burden of Disease database. The Joinpoint regression model was used to describe the change trends. Based on the morbidity and mortality data from 2012 to 2019, a grey model GM (1,1) was constructed to predict the trends in the next ten years. The model was tested by the posterior error method and residual test method. Results: In all populations, men and women, the AAPC values of the crude morbidity rates were 4.15% (95%CI: 3.86%-4.44%, P<0.001), 5.98% (95%CI: 5.65%-6.31%, P<0.001) and 3.23% (95%CI: 2.94%-3.53%, P<0.001) respectively, the AAPC values of age-standardized morbidity rates were 2.47% (95%CI: 2.12%-2.83%, P<0.001), 3.98% (95%CI: 3.68%-4.29%, P<0.001), 1.65% (95%CI: 1.38%-1.93%, P<0.001), the AAPC values of crude mortality rates were 2.09% (95%CI: 1.92%-2.25%, P<0.001), 3.68% (95%CI: 3.45%-3.90%, P<0.001), 0.60% (95%CI: 0.50%-0.71%, P<0.001). The age-standardized mortality rates in men showed a fluctuating trend of first decrease (1990-1994), then increase (1994-2012), and then decrease (2012-2019) (AAPC=1.35%, 95%CI: 1.16%-1.53%, P<0.001). The age-standardized mortality rate in women continuously decreased (AAPC=-1.70%, 95%CI: -1.82%- -1.58%, P<0.001). The GM (1,1) models can be used for medium and long-term predictions. The results of the residual test show that the average relative error values of all models are less than 10.00%, the prediction accuracy values are more than 80.00%, and the prediction effects are good. The results of the posterior error method show that all the prediction results are good except the qualified prediction of the age-standardized morbidity rate in men. In 2029, the crude morbidity rates would increase to 3.57/100 000, 2.78/100 000, and 4.40/100 000, respectively, and the age-standardized incidence rates would increase to 2.38/100 000, 1.89/100 000, and 2.88/100 000, respectively, the crude mortality rates would increase to 0.57/100 000, 0.62/100 000 and 0.53/100 000, and the age-standardized mortality rates would decrease to 0.33/100 000, 0.42/100 000 and 0.27/100 000 in all population, men and women in China. Conclusions: The overall, gender- specific age-standardized mortality rates showed downward trends in the last decade or so, and the prediction results showed that it might further decline. However, the crude morbidity rates, age-standardized and crude mortality rates have been on the rise, and the population aging is becoming increasingly serious in China, which requires close attention and targeted prevention and control measures.

OBJECTIVES: To study the association between oppositional defiant disorder (ODD) and parenting style in children with attention deficit hyperactivity disorder (ADHD). METHODS: A case-control study was performed on 482 children with ADHD, among whom 322 did not have ODD (simple ADHD group) and 160 had ODD (ADHD+ODD group). General demographic data and the Parenting Style Scale assessment scores were collected from the two groups. A multivariate logistic regression analysis was used to identify the association between parenting style and ODD in children with ADHD. RESULTS: There was no significant difference in parenting style scores (including rejection factor, emotional warmth factor, overprotection factor, and preference factor) and general demographic data between the simple ADHD and ADHD+ODD groups (P>0.05). Among the children with the predominantly inattentive type of ADHD, the older the child or the lower the father's educational level, the higher the risk of ODD (P<0.05), while there was no significant association between parenting style and the development of ODD (P>0.05). CONCLUSIONS Parenting style is not significantly associated with the development of ODD in children with ADHD. In clinical practice, it is necessary to eliminate the stereotype that the parents of children with ADHD and comorbid ODD have a poor parenting style and look for the causes of development of ODD from multiple perspectives, so as to provide reasonable intervention recommendations.

Objective: To compare the clinical characteristics of patients with different type of laryngopharyngeal reflux disease in order to study the effect of non-acid reflux on laryngopharyngeal reflux disease. Methods: From January 2015 to January 2020, 349 inpatients or outpatients suspected of having laryngopharyngeal reflux underwent 24-hour multichannel intraluminal impedance pH monitoring (MII-pH). There were 303 male and 46 female patients, with an average age of 56.03 years old ranged from 25 to 81 years old. The reflux symptom index (RSI)and reflux findings score(RFS)were recorded before MII-pH monitoring. The number of acid reflux events and non-acid reflux events in hypopharynx were counted. It was defined mainly acid reflux type when the ratio of acid reflux to all reflux events was greater than 50%, mainly non-acid reflux type when the ratio of non-acid reflux to all reflux events was greater than 50%. The clinical characteristics of patients with different type of reflux were compared. SPSS 19.0 software was used for statistical analysis, and multiple independent samples were compared between groups. The quantitative data were analyzed by multivariate analysis of variance, and the counting data were analyzed by chi-square test, the difference was statistically significant when P<0.05. Results: The 24-hour MII-pH showed that there were 90 patients with no reflux events, 51 patients with mainly acid reflux type, 198 patients with mainly non-acid reflux type and 10 patients with equal acid reflux events and non-acid reflux events. Statistics showed that the RSI(10.72±4.40), RFS(7.70±2.73) and the average number of reflux events(0) in the group without reflux events were significantly lower than those in patients with mainly acid reflux type (RSI 13.16±6.62,RFS 10.08±3.03,average number of reflux events 5.33±3.15,P<0.05) and mainly non-acid reflux type(RSI 13.25±5.54,RFS 8.81±2.54,average number of reflux events 7.93±5.26, P<0.05). There was no significant difference in RSI between the mainly non-acid reflux type group and the mainly acid reflux type group, but the RFS of the mainly non-acid reflux type group was significantly lower than that of the mainly acid reflux type group. The average number of reflux events in the mainly non-acid reflux group was significantly higher than that in the mainly acid reflux type group (P<0.05). Conclusion: The results show that non-acid reflux plays a certain role in laryngopharyngeal reflux disease, but the effect of acid reflux is greater.

The natural forest and artificial shed are the main cropping modes of Coptis chinensis. This study is aimed to reveal the rhizosphere soil bacterial community structure difference between under tow C. chinensis cropping modes-natural forest and artificial shed, and to assist us to completely understand soil quality condition,and provide theoretical guidance for soil improvement and C. chinensis planting. The rhizosphere soil samples of 1-5-year-old C. chinensis under tow cropping modes-natural forest and artificial shed were collected. Illumina high-throughput sequencing technology was used to analyze the alpha diversity, community composition, community structure of soil bacteria under the tow cropping modes,and the effects of soil nutriment indices on soil bacterial community structure. Through the analysis of species number, Shannon, Chao1 index and ACE index of bacterial community, it was found that the bacterial diversity of 1-year-old C. chinensis soil under natural forest cropping mode was significantly lower than that under artificial shed cropping mode, and the diversity of bacterial communities in soil of 2-5-years old C. chinensis were not significant different between two cropping modes. A total of 53 phyla,60 classes,140 orders and 266 families were detected in the rhizosphere soil of C. chinensis under the cropping modes of natural forest, respectively. The rhizosphere soil of C. chinensis under the cropping modes of artificial shed included 54 phyla,65 classes,140 orders and 264 families, respectively. Under the two cropping modes, the top 10 dominant species of bacterial community abundance are the same, they are Proteobacteria, Acidobacteria, Actinobacteria,Bacteroidetes, Planctomycetes, Chloroflexi, Verrucomicrobia, Gemmatimonadetes, Firmicutes and Cyanobacteria, but there are differences in the abundance sequence. The top 10 dominant species of bacterial community abundance accounted for 74.36% to 74.30% of the total bacteria, and 3.15% to 3.92% of the bacteria are unclassified. The results of Metastat analysis showed that the abundance of Gemmatimonadetes in the rhizosphere soil of C. chinensis under the cropping modes the artificial shed was significantly higher than that under the natural forest cropping mode(P<0.05). MRPP analysis of community structure differences showed that under tow cropping modes, there were significant differences in the bacterial community structure of 1-4-year-old soil bacteria, among which the difference between 1-year-old soil samples was the largest. With the increase of cropping years, the difference gradually decreases, and there is no significant difference in the bacterial community structure between 5-year-old soil samples. RDA analysis and correlation analysis of bacterial community structure and soil physical and chemical properties showed that the order of environmental factors on the rhizosphere soil bacteria of Coptis chinensis was: pH>available P> total P> total K>bulk density>total N>available N>organic matter. The results are helpful to understand the soil health of C. chinensis and provide scientific basis and theoretical guidance for soil improvement and C. chinensis planting.

This study is aimed to reveal the rhizosphere soil fungal community structure difference of Coptis chinensis cropping between natural forest and artificial shed modes, and provide theoretical guidance for soil improvement and C. chinensis planting. The rhizosphere soil samples of 1-5-year-old C. chinensis under natural forest and artificial shed modes were collected. Illumina high-throughput sequencing technology was used to analyze the community structure and diversity of soil fungi under the tow cropping modes,and the effects of soil nutriment indices on soil fungal community structure. The results suggested that the abundance and diversity of fungal communities in soil of 2-5-year-old C. chinensis were not significant different in both two cropping modes, but it was significantly higher than that in the 1-year-old C. chinensis. Comparing soil samples from the same year-old C. chinensis under the two cropping modes, it was found that there was no significant difference in the abundance and diversity of fungal communities. The fungal community of the rhizosphere soil was different in composition and abundance between tow cropping modes, and between different planting years. The 17 phyla,59 classes and 155 orders,and 17 phyla,59 classes and 157 orders were detected in the rhizosphere soil of C. chinensis under the cropping modes of natural forest and the artificial shed, respectively. Ascomycota, Basidiomycota and Mortierellomycota were dominant phyla in rhizosphere soil, and the average abundance of the 3 phyla accounted for 74.36% and 74.30% of the total fungi. The results of analysis of similarities showed that there were significant differences in the fungal community structure of 1-year-old and 2-year-old C. chinensis soil fungi, and there was no significant difference in the community structure of 3-5-year-old samples. Under the natural forest cropping mode, there were significant differences among the samples of different years. Under the artificial shed cropping, there were significant differences in fungal community structure between 1-year-old and 3-5-year-old C. chinensis soil, and between 2-year-old and 3-5-year-old C. chinensis soil. The results of canonical correlation analysis showed that soil pH and soil organic matter content were the main factors affecting the soil fungal community structure. Soil organic matter content was positively correlated with Basidiomycota and Cryptomycota, pH was negatively correlated with Basidiomycota and C. ryptomycota. The planting of C. chinensis has promoted the diversity and abundance of rhizosphere fungal community significantly. For the same year-old C. chinensis soil, abundance of fungal community was no significant difference between two cropping modes. There are significant differences in the rhizosphere soil fungal community structure between tow cropping modes in the first two years of planting. Through the interaction between the rhizosphere and the soil and the continuous selection of the rhizosphere to the fungal community, the fungal community structure tended to be the same between the two cropping modes in rhizosphere soil of 3-5-year old C. chinensis. The soil pH and orga-nic matter content were the main factors affecting the change of fungal community structure.

BACKGROUND: Jefferson fracture associated with unstable odontoid fracture is rare, and little reported.Occipito-cervical fusion is the commonly used treatment method, but it causes a severe loss of the motion of cervical vertebrae, which affects the patients' quality of life, so the curative effect is poor.OBJECTIVE: To evaluate the feasibility and therapeutic efficacy of atlantoaxial transpedicular screw fixation for Jefferson fracture associated with unstable odontoid fracture, so as to avoid occipito-cervical fusion and preserve the motion of the atlanto-occipital joint.METHODS: Fifteen patients with Jefferson fracture associated with unstable odontoid fracture from March 2010 to August 2015, were treated with atlantoaxial transpedicular screw fixation. There were 13 cases of Anderson type II and 2 cases of Anderson shallow type lll odontoid fracture, as well as 5 cases combined with transverse atlantal ligament rupture. All patients underwent skull traction after admission, as well as three-dimensional CT was applied preoperatively to determine the atlas pedicle screw trajectory and chose suitable screws. Atlantoaxial transpedicular screw was placed and atlantoaxial joint was reduced under general anesthesia. Bone graft fusion of atlantoaxial joint was applied only for the transverse atlantal ligament.The pain and neurologic function were evaluated by the Visual Analog Scale and the American Spinal Injury Association Impairment Scale before and after operation. The range of motion of the atlanto-occipital joint was observed during follow-up.RESULTS AND CONCLUSION: (1) The mean operation time was (150±41) minutes (120-270 minutes). The mean blood loss was (246±95) mL (160-500 mL). (2) Atlantoaxial transpedicular screws were successfully placed in all patients. No spinal and nerve root injury, or vertebral artery injury occurred intraoperatively. The atlantoaxial achieved good reduction. (3) The follow-up time was 12-36 months. There were nine cases of incomplete spinal cord injury, and 7 cases of obviously improved neurologic function. The visual analog scale scores were significantly improved at 1 year postoperatively, from preoperative (8.15±0.62) to postoperative (1.2±1.4) (P < 0.05). (4) All fractures and bone grafts were healed without loosening or rupture of the screws. The range of motion of the atlanto-occipital joint was (14.6±2.8)° postoperatively. (5) To conclude, atlantoaxial transpedicular screw fixation is effective for Jefferson fracture combined with unstable odontoid fracture, which not only exhibits a high rate of bone healing and stable fixation, but also avoids the occipital-cervical fusion and preserves occipito-atlantal motion.

OBJECTIVETo compare the clinical features of children with different clinical forms of congenital hepatic fibrosis (CHF), and provides a description of the characteristics of childhood CHF.

METHODSSixty children with CHF between January 2002 and June 2015 were enrolled, including 26 children with portal hypertensive CHF (PH CHF), 3 children with cholangitic CHF, 30 children with combined portal hypertensive and cholangitic CHF (mixed CHF), and 1 child with latent forms of CHF. The medical data of 26 children with PH CHF and 30 children with mixed CHF, including gender, age, clinical manifestations, physical signs, laboratory tests and imaging characteristics, were retrospectively studied.

RESULTSFever, jaundice and hepatomegaly were more frequently noted in children with mixed CHF than in those with PH CHF (P<0.05). Splenomegaly and liver cirrhosis occurred more often in children with CHF, but there was no significant difference in the incidences of splenomegaly and liver cirrhosis between the children with PH CHF and mixed CHF. The plasma prothrombin activity, white blood cell counts, platelet counts, mean platelet volume, serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, γ-glutamyl transferase, leucine aminopeptidase, and total bile acids in children with mixed CHF were higher than in those with PH CHF (P<0.05). The decreased international normalized ratio and lower serum albumin levels were more frequently observed in children with mixed CHF than in those with PH CHF (P<0.05).

CONCLUSIONSPH and mixed CHF are common forms in childhood CHF. The children with the two forms of PH usually manifest portal hypertension such as cirrhosis and hepatosplenomegaly. The liver damage may be common in children with mixed CHF.

BACKGROUNDOsteopontin (OPN) is a secreted phosphoglycoprotein (SSP) that is overexpressed in a variety of tumors and was regarded as a molecular marker of tumors. In this study, we intended to demonstrate the role of OPN in human breast cancer cell line MDA-MB-231.

METHODSRecombinant plasmid expressing small interfering RNA (siRNA) specific to OPN mRNA was transfected into MDA-MB-231 cells to generate the stable transfected cell line MDA-MB-343, and the empty plasmid tansfected cells (MDA-MB-neg) or wildtype MDA-MB-231 cells were used as control cells respectively. Expression of OPN, hypoxia inducible factor-1 (HIF-1) and vascular endothelial growth factor (VEGF) proteins was analyzed by Western blotting analysis. The radiosensitivity of cells was determined by detecting cell apoptosis, cell proliferation and cell senescence.

RESULTSHIF-1 and VEGF proteins in MDA-MB-343 cells were significantly downregulated upon the efficient knockdown of OPN expression under either hypoxia or normoxia environment. Moreover, expression of OPN protein was upregualted upon hypoxic culture. Stable OPN-silencing also decreased cell invasion, increased cell apoptosis and cell senescence, as well as reduced clonogenic survival, resulting in increase radiation tolerance.

CONCLUSIONSSuppression of OPN gene expression can enhance radiosensitivity and affect cell apoptosis in breast cancer cells. OPN seems to be an attractive target for the improvement of radiotherapy.
