Objective To explore the influence of regional differences on the body composition of the Miao nationality. Methods The bioelectrical impedance method was used to measure 17 body composition indexes of 357 adults of Miao Nationality in Guizhou (162 males and 195 females) and 471 adults of Miao Nationality in Western Hu'nan (210 males and 261 females). The correlation analysis between body composition and age, One-Way ANOVA and principal component analysis were carried out. Results The visceral fat grade and trunk fat percentage of Miao men in Guizhou and Miao in Western Hu'nan were positively correlated with age, and total muscle mass and trunk muscle mass were negatively correlated with age. The visceral fat grade and trunk fat rate of Miao women in the two regions were positively correlated with age, and the presumed bone mass and trunk muscle mass were negatively correlated with age. The index values of weight, muscle mass, estimated bone mass, water content, visceral fat grade, limb and trunk muscle mass in Guizhou Miao and Miao men in Western Hu'nan were all larger than women, and the body fat rate, limb and trunk fat mass were all smaller than women. The body fat percentages, limbs and trunk fat percentages of Guizhou Miao men and women were similar to those of Xiangxi Miao, and the muscle mass, limbs and trunk muscle mass were less than that of Xiangxi Miao. Conclusion There are obvious regional differences in muscle mass between the Miao nationality in Guizhou and the Miao nationality in Western Hu'nan.

Phenotypes and ATP7B gene variants in 316 children with Wilson disease / 中华儿科杂志

Objectives: To summarize the clinical phenotypes and the variation spectrum of ATP7B gene in Chinese children with Wilson's disease (WD) and to investigate their significance for early diagnosis. Methods: Retrospective analysis was performed on the clinical data of 316 children diagnosed as WD in Guangzhou Women and Children's Medical Center during the period from January 2010 to June 2021. The general situations, clinical manifestations, lab test results, imaging examinations, and ATP7B gene variant characteristics were collected. The patients were divided into asymptomatic WD group and symptomatic WD group based on the presence or absence of clinical symptoms at the time that WD diagnosis was made. The χ2 test, t test or Mann-Whitney U test were used to compare the differences between groups. Results: Among the 316 children with WD, 199 were males and 117 were females, with the age of 5.4 (4.0, 7.6) years at diagnosis; 261 cases (82.6%) were asymptomatic with the age of 4.9 (3.9, 6.4) years; whereas 55 cases (17.4%) were symptomatic with the age of 9.6 (7.3, 12.0) years. The main symptoms invloved liver, kidney, nervous system, or skin damage. Of all the patients, 95.9% (303/316) had abnormal liver function at diagnosis; 98.1% (310/316) had the serum ceruloplasmin lever lower than 200 mg/L; 97.7% (302/309) had 24-hour urine copper content exceeding 40 μg; only 7.4% (23/310) had positive corneal K-F rings, 8.2% (23/281) had abnormal MRI signals in the lenticular nucleus, and all of them had symptoms of damage in liver, kidney or nervous system. Compared with the group of symptomatic WD, asymptomatic group had higher levels of serum alanine aminotransferase and lower levels ceruloplasmin and 24-hour urine copper [(208±137) vs. (72±78) U/L, (55±47) vs. (69±48) mg/L, 103 (72, 153) vs. 492 (230, 1 432) μg; t=9.98, -1.98, Z=-4.89, all P<0.001]. Among the 314 patients completing genetic sequencing, a total of 107 mutations in ATP7B gene were detected, of which 10 are novel variants, and 3 cases (1.0%) had large heterozygous deletion (exons 10 to exon 11) in ATP7B gene. The percentage of missense mutation in asymptomatic WD children was significantly higher than that in symptomatic WD (81.5% (422/518) vs. 69.1% (76/110), χ²=8.47, P<0.05). WD patients carrying homozygous variant of c.2 333G>T had significantly low levels of ceruloplasmin than those not carrying this variant ((23±5) vs. (61±48) mg/L, t=-2.34, P<0.001). Conclusions: The elevation of serum ALT is an important clue for early diagnosis of WD in children, while serum ceruloplasmin and 24-hour urine copper content are specific markers for early diagnosis of WD. In order to confirm the diagnosis of WD, it is necessary to combine the Sanger sequencing with multiplex ligation-dependent probe amplification or other testing technologies.

Methods Totally 24 human indexes of head and face from 4410 cases (1916 males and 2494 females) and 13 Mongolian ethnic groups were measured, and 12 craniofacial indexes were calculated. Correlation analysis was used to study the changes of craniofacial indexes and indexes with age. The method of analysis of variance was used to study whether the differences between the index values and index values of the three age groups were statistically significant. Results With the increase of age, the distance between the two mandibular angles became wider, the mouth widened, the width, height and length of the nose increased, the skin of the upper lip increased, the length and width of the ear increased, the width of the head, forehead, face, mastoid and tragus narrowed, the width of the eyes narrowed, the upper and lower lips thinned, the circumference of the head and the height of the head decreased, and the length of the head did not change significantly. With the increase of age, the Mongolian face becomes narrower and longer, the proportion of the height of the face in the whole head high school increases, the nose becomes wider, and the head appears to be relatively longer, lower and wider. The distance between the left and right frontotemporal points is relatively closer, the mouth cleft appears more slender, and the ratio of length to width of the ear does not change much. Conclusion With the increase of age, the facial features of Mongolian have changed.

Effectiveness of craniotomy and long-term survival in 35 patients with gestational trophoblastic neoplasia with brain metastases: a clinical retrospective analysis / 부인종양

Objective@#To investigate the clinical characteristics, treatments, and prognostic factors among patients with gestational trophoblastic neoplasia (GTN) exhibiting brain metastases who underwent craniotomy. @*Methods@#Thirty-five patients with GTN who had brain metastases and subsequently underwent craniotomies between January 1990 and December 2018 at Peking Union Medical College Hospital were identified using the GTN database. Their clinical manifestations, treatments, outcomes, and prognostic factors were retrospectively analyzed. @*Results@#All 35 patients underwent decompressive craniotomy, hematoma removal, and metastatic tumor resection combined with multiagent chemotherapy. Eighty percent (28/35) achieved complete remission, 11.4% (4/35) achieved partial remission, and 8.6% (3/35) had progressive disease. Not counting 2 patients who were lost to follow-up, 81.8% of the patients (27/33) were alive after a median follow-up of 72 months. The 5-year overall survival rate was 80.4%. Univariate analysis revealed that a history of chemotherapy failure (p=0.020) and a >1-week interval between craniotomy and chemotherapy commencement (p=0.027) were adverse risk factors for survival. Multivariate analysis showed that previous chemotherapy failure remained an independent risk factor for poor survival (odds ratio=11.50; 95% confidence interval=1.55–85.15; p=0.017). @*Conclusion@#Decompressive craniotomy is a life-saving option if metastatic hemorrhage and intracranial hypertension produce a risk of cerebral hernia in patients with GTN who have brain metastases. Higher survival rates and improved prognoses can be achieved through perioperative multidisciplinary cooperation and timely standard postoperative chemotherapy.

Association of liver damage with coronary artery lesion and no response to intravenous immunoglobulin in the acute stage of Kawasaki disease / 中国当代儿科杂志

OBJECTIVES@#To summarize the clinical features of liver damage in children in the acute stage of Kawasaki disease (KD), and to investigate the clinical value of liver damage in predicting coronary artery lesion and no response to intravenous immunoglobulin (IVIG) in children with KD.@*METHODS@#The medical data were collected from 925 children who were diagnosed with KD for the first time in Beijing Children's Hospital from January 1, 2016 to December 31, 2017. According to the presence or absence of abnormal alanine aminotransferase (ALT) level on admission, the children were divided into a liver damage group (n=284) and a non-liver damage group (n=641). A logistic regression analysis was used to investigate the clinical value of the indicators including liver damage in predicting coronary artery lesion and no response to IVIG in children with KD.@*RESULTS@#Compared with the non-liver damage group, the liver damage group had a significantly earlier admission time and significantly higher serum levels of inflammatory indicators (P<0.05). The liver damage group had a significantly higher incidence rate of coronary artery lesion on admission than the non-liver damage group (P=0.034). After initial IVIG therapy, the liver damage group had a significantly higher proportion of children with no response to IVIG than the non-liver damage group (P<0.001). In children with KD, coronary artery lesion was associated with the reduction in the hemoglobin level and the increases in platelet count, C-reactive protein, and ALT (P<0.05), and no response to IVIG was associated with limb changes, the reduction in the hemoglobin level, the increases in platelet count, C-reactive protein, and ALT, and coronary artery lesion (P<0.05).@*CONCLUSIONS@#Compared with those without liver damage, the children in the early stage of KD with liver damage tend to develop clinical symptoms early and have higher levels of inflammatory indicators, and they are more likely to have coronary artery lesion and show no response to IVIG treatment.

Objective To investigate CT features of multifoeal lung adenocarcinoma (MLA) with ground glass opacity and the relationships with pathology.Methods Totally 16 cases (36 lesions) of MLA confirmed by pathology were collected.Based on pathology,the lesions were divided into pre-invasive lesion group (n =7),minimally invasive adenocarcinoma (MIA) group (n=20) and invasive adenocarcinoma (IAC) group (n =9).CT features of all three groups were analyzed and compared with pathology.Results Among 36 lesions,there were 19 lesions (52.78％) with round shape,19 (52.78％) with lobulation,12 (33.33％) with spiculation sign,13 (36.11％) with vacuole sign,12 (33.33％)with blood vessel cluster sign,and 32 lesions (88.89％) with well-defined interface.Seven pre-invasive lesions (7/7,100％) were all pure ground glass opacity (pGGO),while 12 lesions (12/20,60.00％) were pGGO in MIA group,other 8 lesions (8/20,40.00％) were mixed ground glass opacity (mGGO).Only 1 lesion (1/9,11.11％) in IAC group was pGGO,other 8 lesions (1/9,88.89％) were mGGO.There were significant differences of pGGO,spiculation sign,vacuole sign and blood vessel cluster sign among 3 groups (all P＜0.05).There were significant differences of pGGO,spiculation sign and blood vessel cluster sign between pre-invasive lesion and IAC group (P=0.001,0.003,0.001).Significant differences were found in spiculation sign,vacuole sign and blood vessel cluster sign between MIA and IAC group (P=0.014,0.014,0.001).Conclusion CT findings of multiple ground glass opacity are helpful to diagnosis of MLA before surgery.
