Objective To investigate the relationship between chronic severe hepatitis B (CSHB) serum thyroid hor-mone levels and prognosis. Methods By radioimmunoassay on 73 cases of chronic severe hepatitis B patients (study group) serum thyroid hormone levels,and 80 healthy subjects (control group)were sub-fold, and compared the group of death with chronic serum thyroid hormone levels in patients with severe hepatitis B survivors changes. Results serum T3,T4 levels of observation group were significantly lower than the control group(both P<0.01),rT3 levels were sig-nificantly higher (P<0.01), there was no significant difference (P> 0.05) in TSH level of two groups; chronic severe hepatitis B patients who died in serum T3,T4 levels were significantly lower than the survival group (both P<0.05),rT3 levels were significantly higher than survival group(P<0.05). Conclusion The detection of serum thyroid hormone levels to determine the prognosis of chronic severe hepatitis B has significant value.

Objective To investigate the mechanism of Qinggan-Huoxue recipe in the treatment of alcoholic liver disease by observing its function on alcoholic liver disease rat fibroblast growth factor -21 (FGF21). Methods The rats were randomly divided into the blank group (n=10), the carbon tetrachloride group (n=10), the model group (n=11), the Qinggan-Huoxue recipe group (n=10), the Qinggan recipe group (n=9) and the Huoxue recipe group (n=10). Except for the blank group and the carbon tetrachloride group, the other rats were given 10 ml/kg alcohol, corn oil and pyrazole mixture (4.5 ml: 2 ml: 25 mg), once a day, 0.3 ml/kg carbon tetrachloride olive oil solution (carbon tetrachloride: olive oil =1: 3) intraperitoneally, and twice a week for 12 weeks to prepare the alcoholic liver disease model. In the ninth week, the Qinggan-Huoxue recipe group was treated with 4.75 g/kg of Qinggan-Huoxue recipe, the Qinggan recipe group was treated with 1.5 g/kg of Qinggan recipe, and the Huoxue recipe group was treated with 3.25 g/kg of Huoxue recipe, once a day, and 28 d for continuous administration. The pathological changes of liver tissue were observed by HE staining and Masson staining. The serum levels of AST and ALT were detected in rats. The changes of FGF21 protein and mRNA expression were detected by immunohistochemistry, Western blotting and fluorescence quantitative PCR. Results Compared with the model group, the liver weight and liver body ratio in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group were significantly lower (P<0.01). Compared with the model group, the serum ALT (41.95 ± 26.78 U/L, 46.63 ± 21.00 U/L, 37.57 ± 27.85 U/L vs. 138.34 ± 43.35 U/L), AST (102.74 ± 23.55 U/L, 111.50 ± 21.26 U/L, 83.72 ± 37.57 U/L vs. 257.41 ± 162.31 U/L) in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group significantly decreased (P<0.01 or P<0.05). Compared with the model group, the expression of FGF21 protein (1.19 ± 0.07, 1.24 ± 0.12 vs. 0.92 ± 0.04) in Qinggan recipe group and Qinggan-Huoxue recipe group significantly increased (P<0.05), and the expression of FGF21 mRNA (1.25 ± 0.08 vs. 0.95 ± 0.05) in Qinggan-Huoxue recipe group significantly increased (P<0.05). Conclusions FGF21 plays an important role in the alcoholic liver disease. During the process of liver injury, FGF21 increases continuously. Qinggan-Huoxue recipe can improve the content of FGF21 in the treatment of alcoholic liver disease.

ObjectiveTo study the traditional Chinese medicine （TCM） syndromes of children with alopecia areata， and provide evidence for TCM differentiation and treatment in clinic. MethodsA retrospective analysis was conducted on the clinical data of 800 children with alopecia areata admitted to the Hair Medicine Center of the China-Japan Friendship Hospital from January 1， 2012 to December 31， 2021. The clinical data of the children were collected using a four-examination information questionnaire， including clinical characteristics （age of consultation， age of onset， course of disease， family history， severity grading）， alopecia areata-related factors （triggers）， and four-examination information （including sleep， diet， emotions， bladder and bowel function， etc.）. Descriptive frequency analyses， rank sum tests， factor analyses and cluster analyses were performed， and the distribution of the major TCM syndromes was summarised with the clinical data. ResultsThere were 800 children with alopecia areata， including 449 males and 351 females； 8 cases （1.00%） were in infancy， 36 cases （4.50%） were in early childhood， 180 cases （22.50%） were in preschool， 380 cases （47.50%） were in school age， and 196 cases （24.50%） were in puberty at the time of consultation； the average age of consultation was 8.31±3.86 years， the average age of onset of disease was 5.40±3.82 years， and the average duration of disease was 2.94±2.77 years； 527 children （65.87%） with severe alopecia areata； 85 children （13.56%） had a family history of alopecia areata； 772 children （96.50%） had unknown triggers for their first alopecia areata， and 28 children （3.50%） reported the presence of obvious triggers， including fright （9 cases）， high fever （5 cases）， allergic reactions （4 cases）， micronutrient （zinc， iron， etc.） deficiencies （4 cases）， inappropriate diet （2 cases）， environmental factors （1 case， new house renovation）， atopic dermatitis （1 case）， atopic asthma （1 case）， and pneumonia （1 case）. A total of 40 four-examination information items were collected， among which the frequency of kicking quilts was the highest with 380 cases （47.50%）， followed by picky eating （369 cases， 46.13%）， sleeplessness （334 cases， 41.75%）， irritability （334 cases， 41.75%）， partiality towards certain foods （306 cases， 38.25%）， impulsiveness （297 cases， 37.13%）， dry stools （233 cases， 29.13%）， yellow urine （215 cases， 26.88%）， nail biting （213 cases， 26.63%）， bad breath （211 cases， 26.38%）. According to factor analysis and cluster analysis， five types of TCM syndromes were obtained， in order as qi and blood deficiency syndrome （110 cases， 13.75%）， spleen deficiency syndrome （114 cases， 14.25%）， kidney essence deficiency syndrome （140 cases， 17.50%）， dietary stagnation syndrome （150 cases， 18.75%）， and liver depression and spleen deficiency syndrome （286 cases， 35.75%）. Patients in each age group and SALT grading are mainly liver depression and spleen deficiency syndrome. ConclusionThe TCM symptoms of children with alopecia areata are mainly based on qi and blood deficiency syndrome， spleen deficiency syndrome， kidney essence deficiency syndrome， dietary stagnation syndrome， and liver depression and spleen deficiency syndrome， of which liver depression and spleen deficiency syndrome is the most common type at different ages and stages of the disease.
