Clinical Predominance Disease of Traditional Chinese Medicine： Gastroesophageal Reflux Disease / 中国实验方剂学杂志

Gastroesophageal reflux disease （GERD） is a frequently and commonly occurring disease in clinic. In recent decades， with the development in pathophysiology and drug researches， modern medicine has achieved remarkable progress and results in diagnosis and treatment. However， the treatments for non-erosive reflux disease， refractory gastroesophageal reflux disease， proton pump inhibitor resistance， overlap of disease symptoms， and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine （TCM） was widely used in clinical practice， which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine （CACM） and undertaken by the Spleen and Stomach Disease Branch of CACM， "the 12th Youth Salon of Clinical Predominance Disease Series （GERD）" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions， improvement and maintenance of symptoms， response to overlapping disease symptoms， reduction and withdrawal of acid suppressors， and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths， combing the difficulties of modern medical diagnosis and treatment， which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.

OBJECTIVE@#To explore the clinical manifestations and genetic characteristics of patients with congenital central hypothyroidism due to variants of IGSF1 gene.@*METHODS@#Clinical data, results of genetic testing, and follow-up of four patients admitted to Children's Hospital of Soochow University during 2017 to 2021 were retrospectively analyzed.@*RESULTS@#All of the four patients were males. Patient 1 had presented neonatal jaundice, patients 2 and 3 were admitted for growth retardation during childhood, and thyroid function test indicated slightly low free thyroxine (FT4), patient 4 was found to have reduced FT4 in the neonatal period. Genetic testing revealed that all of the four patients have harbored pathogenic variants of the IGSF1 gene, which were all inherited from their mothers. The thyroid functions in all patients were well controlled with oral levothyroxine and regular follow-up.@*CONCLUSION@#Pathogenic variants of the IGSF1 gene probably underlay the congenital central hypothyroidism with a variety of clinical manifestations, and genetic testing can facilitate the diagnosis at an early stage.

MELAS syndrome caused by A3252G mutation in MT-TL1 gene: One case report and literature review / 中华内分泌代谢杂志

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes(MELAS) is one of the most common inherited mitochondrial diseases. This paper reports a rare mutation associated with MELAS syndrome, the m. 3252 A>G mutation in the MT-TL1 gene encoding the mitochondrial tRNALeu(UUR). The 6-year-old girl suffered from recurrent convulsion and lactic acidemia. The mtDNA sequencing detected a variant m. 3252A>G(MT-TL1 gene) in the proband and her maternal relatives. The heteroplasmic levels in peripheral blood and urine sediment were 66.53% and 97.42%, respectively, which were obviously higher than those of her maternal relatives. Together with 3 previously reported cases, the variant m. 3252A>G could be classified pathogenic. All the reported pathogenic variants in MT-TL1 gene were reviewed to explore the genotype-phenotype correlations of pathogenic variants in MT-TL1 gene.

Value of fibrinogen to albumin ratio on predicting spontaneous recanalization of infarct-related artery in patients with acute ST-segment elevation myocardial infarction / 中华心血管病杂志

Objective@#To investigate the value of fibrinogen to albumin ratio (FAR) at admission on predicting spontaneous recanalization of infarct-related artery (IRA) in patients with acute ST-segment elevation myocardial infarction (STEMI).@*Methods@#Clinical data from 255 acute STEMI patients ((61.1±11.2) years old, 189 males) who underwent emergency coronary angiography within 12 hours in our hospital from December 2015 to April 2018 were retrospectively analyzed. The acute STEMI patients were divided into non-spontaneous recanalization group (thrombolysis in myocardial infarction (TIMI) flow grade 0-1, 203 cases) and spontaneous recanalization group (TIMI flow grade 2-3, 52 cases). Multivariate logistic regression analysis was used to evaluate related factors of IRA spontaneous recanalization. The receiver operating characteristic (ROC) curve was used to evaluate the value of FAR in predicting spontaneous coronary recanalization.@*Results@#There was no significant difference in age,gender, hypertension, diabetes, smoking,systolic blood pressure,diastolic blood pressure,heart rate, duration of chest pain, type of infarction, infarct-related artery, door-to-balloon time, and drug used before admission between non-spontaneous recanalization group and spontaneous recanalization group (all P>0.05). The FAR and high-sensitivity C-reactive protein levels were significantly lower in the spontaneous recanalization group than in the non-spontaneous recanalization group (8.20±1.85 vs. 11.02±2.75, P<0.001; (6.87±3.36) g/L vs. (8.51±3.72) g/L, P=0.004). Multivariate logistic regression analysis showed that FAR (OR=0.492, 95%CI 0.354-0.686, P<0.001), serum uric acid (OR=0.994, 95%CI 0.989-0.999, P=0.018) and high-sensitivity C-reactive protein (OR=0.774, 95%CI 0.614-0.975, P=0.030) were independent negative correlation with spontaneous recanalization of infarct-related artery in patients with acute STEMI. The ROC curve showed that the area under the curve of FAR predicting spontaneous recanalization of infarct-related artery in patients with acute STEMI was 0.807 (95%CI 0.630-0.758, P<0.001), and the diagnostic threshold was 9.26, the sensitivity was 76.9%, the specificity was 75.9%.@*Conclusion@#The level of admission FAR has certain predictive value for spontaneous recanalization of infarct-related arteries in patients with acute STEMI.

Clinical characteristics of thyroid hormone resistance syndrome in two cases with different subtypes / 中华儿科杂志

Objective@#To analyze the clinical characteristics of children with two types of thyroid hormone resistance (RTH) syndrome, and to detect the variants of thyroid hormone receptor alpha(TRα) and TRβ gene in children.@*Method@#Two children with RTH were reported in regard to clinical manifestation, laboratory examination and genetic variants. Some related reports in literature were reviewed.@*Result@#Case 1 was a girl, 10 years old, with thyroid enlargement for several days and without thyrotoxicosis. Laboratory work-up revealed that free thyroxine (FT4) was 65.77 pmol/L (reference 12-22) , free triiodothyronine (FT3) was 15.36 pmol/L (reference 3.1-6.8) and thyroid stimulating hormone (TSH) level was normal. There was a likely pathogenic missense variant detected in TRβ gene and this patient was diagnosed with RTHβ. Case 2 was a boy, 3 years old, with classic features of hypothyroidism(growth retardation, developmental retardation, skeletal dysplasia) but had only borderline-abnormal thyroid hormone levels. Targeted sequencing showed a de novo heterozygous nonsense variant in TRα gene which is a pathogenic variant and this patient been diagnosed with RTHα.@*Conclusion@#Thyroid enlargement is a common clinical manifestation of RTHβ, with laboratory work-up reveals elevated FT4 and FT3 levels but TSH level is normal. The clinical manifestations of RTHα are similar to those of hypothyroidism, but the thyroid hormone levels are almost normal. The gene sequence and the pathogenicity analysis for TRα and TRβ will help to make a definitive diagnosis.
