Objective:To study the epidemic characteristics and clinical symptoms of patients with Hashimoto's thyroiditis (HT) in Shandong Province, and to provide a basis for further optimizing the clinical treatment strategies for HT.Methods:Data on HT patients admitted to Shandong Provincial Center for Disease Control and Prevention from January 2018 to December 2023 were collected. A retrospective analysis was conducted to analyze their epidemiological characteristics, clinical symptoms, and auxiliary examination results.Results:A total of 192 HT patients' data were included, comprising 42 males (21.87%) and 150 females (78.13%). The average age of patients was 40.38 years old, ranging from 9 to 74 years old. Most patients resided in urban areas (129 cases, 67.19%). HT cases occurred throughout the year in every mouth, with higher incidence in June (32 cases, 16.7%) and July (20 cases, 10.4%), lower incidence in March (8 cases, 4.2%) and April (10 cases, 5.2%), and sporadic cases in other months. Based on clinical manifestations, among all HT patients, there were 66 cases (34.38%) of Hashitoxicosis type, 11 cases (5.73%) of pseudothyrotoxicosis type, 7 cases (3.65%) of exophthalmic type, 5 cases (2.60%) of subacute thyroiditis-like type, 3 cases (1.56%) of juvenile type, 35 cases (18.23%) of fibrous type, 39 cases (20.31%) of thyroid adenoma or carcinoma type, and 26 cases (13.54%) of other autoimmune diseases type. Based on disease progression, among all HT patients, there were 61 cases (31.77%) in the hyperthyroid phase, 16 cases (8.33%) in the hyperthyroid-hypothyroid coexisting phase, and 115 cases (59.90%) in the hypothyroid phase. Based on clinical symptoms, among all HT patients,there were 78 cases(40.62%) of neck mass symptoms, 101 cases (52.60%) of digestive system symptoms, and 95 cases (49.48%) of low metabolic symptoms. Laboratory tests revealed that 144 cases had elevated levels of both thyroglobulin antibody and thyroid peroxidase antibody. Color ultrasound examination showed strip-like echoes in the thyroid in 99 cases (51.56%) and grid-like echoes in 43 cases (22.40%). After treatment with antithyroid drugs or appropriate thyroid hormone supplementation, all 192 HT patients experienced symptom relief.Conclusions:HT patients in Shandong Province were predominantly female and urban residents. Common clinical symptoms included anterior neck swelling, constipation, fever, and weight gain. Early detection, diagnosis, and treatment could delay disease progression.

The clinical data of a child with neurodevelopmental disorders caused by a new mutation in the POLR2A gene were retrospectively analyzed.The patient was a 4-year and 2-month-old girl who presented at Xiamen Hospital, Children′s Hospital of Fudan University in June 2024 with clinical manifestations of early infantile hypotonia, muscle atrophy of both lower limbs, global developmental delay (including delays in motor and language development, mental retardation, etc.), sleep difficulties, feeding difficulties, autistic behaviors (namely, social withdrawal), epilepsy, and auditory deficits.The child had one seizure at the age of 2 years and 8 months and one at the age of 4 years, but seizures are currently controlled by drugs.Cranial magnetic resonance imaging and CT showed agenesis of the corpus callosum, bilateral ventricular widening and cerebellar hypoplasia.Whole exome sequencing showed a new mutation c. 3364C>T (p.P1122S) in the POLR2A gene (NM_000937) in the child, and no related gene variants were found in either parental lineage.According to the American College of Medical Genetics and Genomics rating guidelines, it was determined to be a suspected pathogenic variant (PS2+ PM2+ PP3+ PP4).The mutation site has not been reported at home and abroad.The c. 3364C > T ( p. P1122S ) mutation of the POLR2A gene can cause neurodevelopmental disorders, severe phenotypes and poor long-term prognosis.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Objective:To investigate the relationship between iodine nutrition level and thyroid disease.Methods:Totally 299 patients with thyroid disease who were treated at Shandong Provincial Institute for Endemic Disease Prevention and Control from 2016 to 2018 were selected as case group which was further divided into Graves' disease group (GD group, 137 patients), chronic lymphocytic thyroiditis group (HT group, 90 patients) and thyroid nodule group (72 patients). At the same time, 75 healthy people with no history of thyroid disease, normal thyroid color ultrasound and thyroid function were selected as control group. Morning urine was collected and urinary iodine was detected by arsenic cerium catalytic spectrophotometry. Fasting venous blood was extracted, and serum levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid globulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) were detected by electrochemiluminescence method. Results:The difference of median urinary iodine in the 4 groups was statistically significant ( H = 42.530, P < 0.05). The medians urinary iodine in GD and HT groups (326.79, 341.91 μg/L) were higher than those of thyroid nodule group and control group (235.01, 187.32 μg/L, P < 0.05). The levels of TSH, FT 3 and FT 4 in GD group were compared with those of control group, and the differences were statistically significant ( P < 0.05). The positive rates of TgAb and TPOAb in HT group were significantly higher than those in GD, thyroid nodule and control groups, and the positive rates of TgAb and TPOAb in GD group were higher than those in thyroid nodule and control groups ( P < 0.05). Conclusions:GD and HT patients have excessive iodine nutrition, and high iodine intake may lead to the occurrence of these thyroid diseases (GD and HT). Thyroid function test combined with laboratory urinary iodine test can be used to diagnose thyroid diseases simply and quickly.

Objective:To use the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ) to analyze the cognitive function status of patients after intracranial aneurysms surgery, and to explore its effects on evaluating the cognitive function of patients after intracranial aneurysms surgery.Methods:The patients after intracranial aneurysms surgery treated in the Department of Neurology and Neurosurgery in 3 Class Ⅲ Grade A hospitals in Zhengzhou between November 2018 and June 2019 and healthy controls were selected by convenient sampling. MoCA-BJ and Addenbrooke's Cognitive Examination-Revised (ACE-R) were used to evaluate the cognitive function of 306 patients after intracranial aneurysms surgery and 47 healthy controls. After 14 days, 30 subjects from the healthy control group were randomly selected for the MoCA-BJ test again. Cronbach's α coefficient was used to analyze the internal consistency of MoCA-BJ, and the Pearson correlation coefficient test was used to retest its reliability. ACE-R was employed to determine the convergent validity of MoCA.Results:The Cronbach's α coefficient of MoCA-BJ was 0.910 ( P<0.05) , and the retest reliability was 0.879 ( P<0.01) . The correlation analysis between the total scores of MoCA-BJ and ACE-R showed a positive correlation between the two ( r=0.883, P<0.01) . The optimal cut-off value of MoCA-BJ screening for patients with mild cognitive impairment (MCI) after intracranial aneurysm surgery was 25.5, which was corresponding to 83.0% in its screening sensitivity, 87.9% in specificity, and 0.652 in the Kappa value, showing good consistency. Receiver's operating characteristic curve (ROC) analysis results showed that the area under the curve ( AUC) was 0.924 ( SE=0.019, 95% CI: 0.888-0.960, P<0.01) . Conclusions:MoCA-BJ has good internal consistency reliability, retest reliability and convergent validity, and is suitable for MCI screening of patients after intracranial aneurysm surgery.

Objective To analyze the relationship between blood glucose,blood lipid and body mass index (BMI) in elderly patients with hypertension.Methods Form January 2016 to December 2017,376 hypertensive patients over 65 year old in Jinan city were enrolled in this study.The sex,age,BMI,fasting blood glucose and blood lipid were investigated and tested.The prevalence of coronary heart disease and diabetes mellitus in hypertensive patients were investigated,and the relationship between BMI and blood glucose,blood lipid and liver function index were explored.Results Of 376 hypertensive patients,the detection rate of diabetes mellitus was 21.01％ (79/376),221 cases were diagnosed with coronary heart disease,with the detection rate of 58.78％.With the rise of BMI,fasting blood glucose showed an upward trend.Person correlation analysis showed that there was a significant positive correlation between BMI and fasting blood glucose(r =0.167,P =0.003).The difference between TG and TC in different BMI groups was statistically significant(FTG =12.48,P ＜ 0.001;Frc =4.83,P ＜ 0.001).The content of alanine transaminase in the overweight group and obese group was significantly higher than that in the normal body weight group,the difference was statistically significant(F =5.24,P =0.005).Conclusion For elderly hypertensive patients,it is urgent to test blood glucose and coronary heart disease screening.For people over the age of 65,obesity is still an important risk factor for hyperlipidemia and hyperglycemia.Therefore,body weight control is needed in elderly patients with hypertensive.

Objective To understand the implementation effects of control measures and the dynamic prevalence of drinking water-borne endemic fluorosis in Shandong Province.Methods From 2013 to 2017 in Shandong Province drinking water-borne endemic fluorosis areas,in accordance with the method of simple random sampling,10 monitored counties were selected,10 water fluorine decreasing projects were investigated of its running effect,and water fluoride was detected.In each monitored county,3 villages in the diseased areas were selected as fixed monitored villages.If the monitored village had changed its water,the operation of the project would be investigated.If the monitored village had not changed the water,one water sample would be collected according to 5 directions of east,west,south,north and middle to determine the water fluorine.All children aged from 8 to 12 in the village were also examined for dental fluorosis.X-ray fluorosis and urinary fluorosis in adults aged over 25 were detected in 2013 and 2017.Results From 2013 to 2017,in monitored counties,the normal operation rate of improved-water defluoridation projects was 99.19％ (368/371),the qualified rate of water fluoride content was 66.85％ (248/371).In 128 improved water projects,the normal operation rate was 100.00％ (128/128),the qualified rate of water fluoride content was 67.19％ (86/128).The average detection rate of dental fluorosis and community fluorosis index (CFI) in children aged 8-12 were 33.92％ (2 608/7 689) and 0.68 in all monitored counties from 2013 to 2017.The detection rate presented a declining trend year by year (x2 =152.47 P ＜ 0.01).The average detection rate and CFI in the villages with normal operation projects and qualified fluoride content were 26.10％ (1 311/5 023) and 0.47.The detection rate presented a declining trend year by year (x2 =207.67 P ＜ 0.01).The detection rate and CFI in the villages with water improvement projects under abnormal operation or excessive fluoride were 48.65％ (1 297/2 666) and 0.90.The detection rate of dental fluorosis in the villages with normal operation projects and qualified fluoride content was lower than the rate of the villages with water improvement projects under abnormal operation or excessive fluoride (x2 =193.98,P ＜ 0.01).In 2013 and 2017,X-ray detection rates of skeletal fluorosis in adults aged over 25 were 8.04％ (119/1 481) and 6.04％ (81/1 342),respectively.The adult urinary fluoride geometric mean values (1.24,1.49 mg/L) were lower than the normal limit of 1.6 mg/L both in qualified villages of water ffuoride content and exceeding-standard villages in 2017.Conclusions In Shandong Province,the effective water improvement has acquired some effects in control of drinking water-borne endemic fluorosis.But the water fluoride content of improved water defluoridation projects exceeds the national standard seriously and fluorosis has not been effectively controlled.
