Objective:To understand the applicability of different thyroid volume correction methods for school-age children in Wuhan, and to explore the appropriate thyroid volume correction methods for school-age children in Wuhan.Methods:From May to August 2019, Hongshan, Hanyang, Hannan, Jiangxia and Dongxihu districts of Wuhan were divided into five sampling areas according to five directions: east, west, south, north and middle. One primary school was selected from each area, and 40 non-boarding students aged 8 - 10 years old (gender balanced) were selected from each primary school as survey subjects. Random urine sample and household edible salt sample were collected to detect urinary iodine and salt iodine contents, and the height, weight and thyroid volume of the children were measured. At the same time, the thyroid volume was corrected by height corrected volume index 1 (HVI1), weight and height corrected volume index (WHVI), body mass index corrected volume (BMIV), body surface area corrected volume (BSAV) and height corrected volume index 2 (HVI2).Results:A total of 1 000 children aged 8- 10 years old were investigated, including 499 boys and 501 girls; among them, there were 269, 321 and 410 children aged 8, 9 and 10 years old, respectively. The median urinary iodine was 247.50 μg/L; the median salt iodine was 23.20 mg/kg; the height, weight and thyroid volume were 140.00 (133.00, 146.00) cm, 31.00 (27.00, 37.00) kg and 2.56 (2.13, 3.21) ml, respectively. A total of 30 children with goiter were detected, and the goiter rate was 3% (30/1 000). The thyroid volumes of boys and girls were 2.57 (2.16, 3.28) and 2.56 (2.10, 3.16) ml, respectively, and the difference was not statistically significant ( U = - 0.981, P > 0.05). The thyroid volumes of children aged 8, 9 and 10 years old were 2.31 (1.98, 2.81), 2.68 (2.13, 3.30) and 2.74 (2.28, 3.35) ml, respectively, and the differences were statistically significant ( H = 47.585, P < 0.01). Spearman correlation analysis showed that the original thyroid volume was positively correlated with height and weight in children aged 8, 9 and 10 years old ( P < 0.01). After HVI1 correction, no correlation was found between thyroid volume and height in children aged 8 years old ( P > 0.05), but thyroid volume was positively correlated with weight ( P < 0.01); thyroid volume was positively correlated with height and weight in children aged 9 and 10 years old ( P < 0.01). After WHVI correction, the thyroid volumes of children aged 8, 9, and 10 years old were negatively correlated with height and weight ( P < 0.01). After BMIV correction, the thyroid volume was positively correlated with height in children aged 8, 9, and 10 years old ( P < 0.01); thyroid volume was negatively correlated with weight in children aged 10 years old ( P < 0.05). After BSAV correction, thyroid volume was positively correlated with weight in children aged 9 years old ( P < 0.05). After HVI2 correction, thyroid volume was positively correlated with weight in children aged 9 years old ( P < 0.01). The thyroid volume obtained by the 5 correction methods were all smaller than the original thyroid volume, and the thyroid volume after BSAV correction was the closest to the original thyroid volume, with a difference of 0.87% - 13.87%. Conclusions:The thyroid volume of school-age children in Wuhan is affected by age, height, and weight, judgment of goiter should be corrected for these factors. BSAV is relatively independent and stable, it can eliminate the effect of height and weight on thyroid volume. It is initially considered that BSAV is suitable for the correction of thyroid volume in school-age children in Wuhan.

Background and purpose:It has a signiifcant effect for erlotinib on treatment of patients with epidermal growth factor receptor mutation in advanced non-small cell lung cancer (NSCLC). But almost all patients will eventually progress for the resistance of drug. This study was to evaluate the efifcacy and safety of retreatment of erlotinib in patients with advanced NSCLC. Methods:It was a retrospective analysis of the 46 advanced NSCLC patients who previously treated with erlotinib and had clinical beneift. The patients were given erlotinib 150 mg orally once daily after failure to other medications until disease progression or the occurrence of intolerable toxicity. The clinical features, therapeutic effect and survival were analyzed. Results: The objective response rate of retreatment with erlotinib was 28.3%. The disease control rate was 60.9%. The rate of symptom relief was 45.7%. The median progression-free survival was 3.6 months. The median overall survival was 7.3 months. One-year survival rate was 8.7%. The median progression-free survival was signiifcant longer in the patients who stopped taking erlotinib more than 6 months than those less than 6 months (P=0.002). The median overall survival was signiifcant longer in the patients whose ECOG ≤2 than those ECOG >2 (P=0.038). The most common drug-related adverse events were rash and diarrhea. Conclusion:The retreatment of erlotinib could possibly prolong the survival time of patients who previously treated with erlotinib and had clinical beneift.

In this study, a combination of metabolomics and network pharmacology was used to study the pharmacodynamic substances and mechanism of action of Yiyi Fuzi powder (YYFZ) on rheumatoid arthritis (RA) rats. The animal experiments were conducted in accordance with the requirements of the Experimental Animal Ethics Committee of Tianjin University of Traditional Chinese Medicine (approval number: TCM-LAEC2021241). The metabolomic analysis using UPLC-Q-TOF/MS technique identified 22 metabolites, including arachidonic acid, tryptophan, linoleic acid, phenylalanine, as significant biomarkers for the treatment of RA with YYFZ, and they were significantly regressed after YYFZ treatment. The analysis of YYFZ blood components also revealed that 11 blood components, including hypaconitine, benzoylhypaconitine, and deoxyaconitine, may be the components that exert direct pharmacological effects in YYFZ

OBJECTIVETo explore the effect of Jinwu Jiangu Recipe (JJR) on the expression of synovial cells' nuclear factor-kappaB (NF-kappaB) and serum interleukin 17 (IL-17) in collagen induced arthritis (CIA) rats.
METHODSTotally 60 Wistar rats were randomly divided into 6 groups, i.e., the blank control group, the model group, high, middle, and low dose JJR treatment groups, and the tripterygium control group, 10 in each group. Except rats in the blank control group, CIA model was established in rats of the rest 5 groups. Then they were treated from the 7th day of modeling. After 4 weeks of medication they were sacrificed, serum collected, and synovium of joints were isolated. The expression of serum IL-17 was detected in synovium of joints by enzyme linked immunosorbent assay (ELISA). And the expression of NF-kappaB/P65, Ikappabetaalpha and NF-KappaB/P50 were detected by Western blot.
RESULTSCompared with the blank control group, the serum IL-17 level increased in the model group (P <0. 01). Compared with the model group, the serum IL-17 level obviously decreased in high and middle dose JJR groups and the tripterygium control group (P < 0.01). Results of Western blot showed, when compared with the blank control group, protein activities of NF-kappaB/P65 and NF-kappaB/P50 were significantly enhanced in the model group (P < 0.01). Compared with the model group, protein activities of NF-kappaB/P65 and NF-kappaB/P50 significantly decreased in high and middle dose JJR groups and the tripterygium control group (P < 0.05, P < 0.01). All indices mentioned above were higher in the low dose JJR group than in the tripterygium control group (P < 0.05, P < 0.01).
CONCLUSIONJJR could lower the expression of serum IL-17 in CIA model rats, and inhibit protein activities of NF-kappaB/P65 and NF-kappaB/P50.

Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein, we report the imaging findings of beta-thalassemia in a 13-year-old boy complaining of weakness of left side of the body and gait disturbance; CT and MRI revealed an extradural mass in the right temporoparietal region.
