Holocarboxylase synthetase deficiency induced by HLCS gene mutations: a rare disease study / 中国当代儿科杂志

A boy, aged 16 months, attended the hospital due to head and facial erythema for 15 months and vulva erythema for 10 months with aggravation for 5 days. The boy developed perioral and periocular erythema in the neonatal period and had erythema and papules with desquamation and erosion in the neck, armpit, and trigone of vulva in infancy. Blood gas analysis showed metabolic acidosis; the analysis of amino acid and acylcarnitine profiles for inherited metabolic diseases and the analysis of organic acid in urine suggested multiple carboxylase deficiency; genetic testing showed a homozygous mutation of c.1522C>T(p.R508W) in the HLCS gene. Finally the boy was diagnosed with holocarboxylase synthetase deficiency and achieved a good clinical outcome after oral biotin treatment. This article analyzes the clinical data of a child with holocarboxylase synthetase deficiency and summarizes the etiology, diagnosis, and treatment of this child, so as to provide ideas for clinicians to diagnose this rare disease.

Recurrent vulvar rashes in a girl aged 22 months for more than half a year / 中国当代儿科杂志

A girl, aged 22 months, attended the hospital due to recurrent vulvar rashes for more than half a year. Skin biopsy showed Langerhans cell histiocytosis, and evaluation of systemic conditions showed no systemic involvement. Therefore, the girl was diagnosed with Langerhans cell histiocytosis (skin type). In conclusion, for rashes on the vulva alone, if there are no specific clinical manifestations, the possibility of Langerhans cell histiocytosis should be considered after molluscum contagiosum, sexually transmitted diseases, and Fordyce disease are excluded.

Situational Analysis of Low-density Lipoprotein Cholesterol Control and the Use of Statin Therapy in Diabetes Patients Treated in Community Hospitals in Nanjing, China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Comprehensive management of diabetes should include management of its comorbid conditions, especially cardiovascular complications, which are the leading cause of morbidity and mortality among patients with diabetes. Dyslipidemia is a comorbid condition of diabetes and a risk factor for cardiovascular complications. Therefore, lipid level management is a key of managing patients with diabetes successfully. However, it is not clear that how well dyslipidemia is managed in patients with diabetes in local Chinese health-care communities. This study aimed to assess how well low-density lipoprotein cholesterol (LDL-C) was managed in Nanjing community hospitals, China.</p><p><b>METHODS</b>We reviewed clinical records of 7364 diabetic patients who were treated in eleven community hospitals in Nanjing from October 2005 to October 2014. Information regarding LDL-C level, cardiovascular risk factors, and use of lipid-lowering agents were collected.</p><p><b>RESULTS</b>In patients without history of cardiovascular disease (CVD), 92.1% had one or more CVD risk factors, and the most common CVD risk factor was dyslipidemia. The overall average LDL-C level was 2.80 ± 0.88 mmol/L, which was 2.62 ± 0.90 mmol/L and 2.82 ± 0.87 mmol/L in patients with and without CVD history respectively. Only 38% of all patients met the target goal and 37.3% of patients who took lipid-lowering agents met target goal. Overall, 24.5% of all patients were on lipid-lowering medication, and 36.3% of patients with a CVD history and 20.9% of patients without CVD history took statins for LDL-C management. The mean statin dosage was 13.9 ± 8.9 mg.</p><p><b>CONCLUSIONS</b>Only a small portion of patients achieved target LDL-C level, and the rate of using statins to control LDL-C was low. Managing LDL-C with statins in patients with diabetes should be promoted, especially in patients without a CVD history and with one or more CVD risk factors.</p>

PMExposure Elicits Oxidative Stress Responses and Mitochondrial Apoptosis Pathway Activation in HaCaT Keratinocytes / 中华医学杂志(英文版)

<p><b>Background:</b>PM(aerodynamic diameter ≤ 2.5 μm) is a dominant and ubiquitous air pollutant that has become a global concern as PMexposure has been linked to many adverse health effects including cardiovascular and pulmonary diseases. Emerging evidence supports a correlation between increased air PMlevels and skin disorders although reports on the underlying pathophysiological mechanisms are limited. Oxidative stress is the most common mechanism of PM-induced adverse health effects. This study aimed to investigate PM-induced oxidative damage and apoptosis in immortalized human keratinocyte (HaCaT) cells.</p><p><b>Methods:</b>HaCaT cells were exposed to 0, 25, 50, 100, or 200 μg/ml PMfor 24 h. Reactive oxygen species (ROS) generation, lipid peroxidation products, antioxidant activity, DNA damage, apoptotic protein expression, and cell apoptosis were measured.</p><p><b>Results:</b>PMexposure (0-200 μg/ml) for 24 h resulted in increased ROS levels (arbitrary unit: 201.00 ± 19.28, 264.50 ± 17.91, 305.05 ± 19.57, 427.95 ± 18.32, and 436.70 ± 17.77) and malondialdehyde production (0.54 ± 0.05 nmol/mg prot, 0.61 ± 0.06 nmol/mg prot, 0.68 ± 0.05 nmol/mg prot, 0.70 ± 0.05 nmol/mg prot, and 0.76 ± 0.05 nmol/mg prot), diminished superoxide dismutase activity (6.47 ± 0.28 NU/mg prot, 5.97 ± 0.30 NU/mg prot, 5.15 ± 0.42 NU/mg prot, 4.08 ± 0.20 NU/mg prot, and 3.76 ± 0.37 NU/mg prot), and increased DNA damage and apoptosis in a dose-dependent manner in HaCaT cells. Moreover, cytochrome-c, caspase-3, and caspase-9 expression also increased proportionately with PMdosing.</p><p><b>Conclusion:</b>PMmight elicit oxidative stress and mitochondria-dependent apoptosis that likely manifests as skin irritation and damage.</p>

Chronic Kidney Disease and Associated Cardiovascular Risk Factors in Chinese with Type 2 Diabetes

BACKGROUND: To determine the frequency of chronic kidney disease (CKD) and its associated risk factors in Chinese type 2 diabetic patients, we conducted a cross-sectional study in Nanjing, China, in the period between January 2008 and December 2009. METHODS: Patients with type 2 diabetes under the care by Jiangsu Province Official Hospital, Nanjing, China were invited for assessment. CKD was defined as the presence of albuminuria or estimated glomerular filtration rate or =30 mg/g. RESULTS: We recruited 1,521 urban Chinese patients with type 2 diabetes (mean age, 63.9+/-12.0 years). The frequency of CKD and albuminuria was 31.0% and 28.9%, respectively. After adjusted by age and sex, hypertension, anemia and duration of diabetes were significantly associated with CKD with odds ratio (95% confidence interval) being 1.93 (1.28 to 2.93), 1.70 (1.09 to 2.64), and 1.03 (1.00 to 1.06), respectively. CONCLUSION: In conclusion, CKD was common in the urban Nanjing Chinese with type 2 diabetes. Strategies to prevent or delay progression of kidney disease in diabetes should be carried out at the early disease course of type 2 diabetes.

Validity of Glycated Hemoglobin in Screening and Diagnosing Type 2 Diabetes Mellitus in Chinese Subjects

BACKGROUND/AIMS: The application of glycated hemoglobin (HbA1c) for the diagnosis of diabetes is currently under extensive discussion. In this study, we explored the validity of using HbA1c as a screening and diagnostic test in Chinese subjects recruited in Nanjing, China. METHODS: In total, 497 subjects (361 men and 136 women) with fasting plasma glucose (PG) > or = 5.6 mmol/L were recruited to undergo the oral glucose tolerance test (OGTT) and HbA1c test. Plasma lipid, uric acid, and blood pressure were also measured. RESULTS: Using a receiver operating characteristic curve, the optimal cutoff point of HbA1c related to diabetes diagnosed by the OGTT was 6.3%, with a sensitivity and specificity of 79.6% and 82.2%, respectively, and the area under the curve was 0.87 (95% confidence interval, 0.83 to 0.92). A HbA1c level of 6.5% had a sensitivity and specificity of 62.7% and 93.5%, respectively. When comparing the HbA1c > or = 6.5% or OGTT methods for diagnosing diabetes, the former group had significantly higher HbA1c levels and lower levels of fasting and 2-hour PG than the latter group. No significant difference was observed in the other metabolism indexes between the two groups. CONCLUSIONS: Our results suggest that HbA1c > or = 6.5% has reasonably good specificity for diagnosing diabetes in Chinese subjects, which is in concordance with the American Diabetes Association recommendations.

Comparative proteomic analysis of cerebral cortex between middle cerebral artery occlusion rats and normal controls / 生物工程学报

In order to provide a complete picture of pathogenesis in cerebral ischemia, cerebral cortex in MCAO rats were analysed for alteration in their proteomes. Comparative proteome analysis was used to compare signal corresponding to individual cerebral cortex proteins on a two-dimensional gel between MCAO rats and the normal control (NC) group. After sample preparation, two-dimensional electroghoresis separated proteins were stained with Commassie Brilliant Blue. The image data were analyzed on a Dell computer using Image Master v 3.01 software. In cerebral cortex, 30 proteins were differentially expressed in MCAO rats compared with NC. There were 11 spots significantly increased, 15 spots significantly decreased and Adenylate kinase isoenzyme 1 was detected only in NC group, biliverdin reductase B, small inducible cytokine A4 [Precursor] only in MCAO group. Peroxiredoxin 2 divided into two points in MCAO6h group. In the end, this approach may lay a foundation for the further investigation of pathogenic mechanisms in cerebral ischmic injury.

Familial pedigree analysis of Shen-yin deficiency syndrome in families with type 2 diabetes mellitus GU / 中国中西医结合杂志

To analyse the familial aggregation and genetic predisposition of Shen-yin deficiency syndrome (SYDS) in families with diabetes mellitus type 2 (DM2). Methods One hundred and forty-one DM2 patients were collected from 32 family lines in Nanjin area, in which the probands were differentiated as DM2 with SYDS. On them, genetic analysis on the characteristics of SYDS was conducted using pedigree analysis, morbidity and heritability of the first-degree relatives of the probands were calculated, and the action of familial SYDS factor on the genesis of the syndrome was assessed by multiple factors regression analysis. Results The morbidity rate of SYDS in the first-degree relatives of the probands was 33.71%, and the heritability, calculated by Falconer formula, was 80.6%. The fitting result of regression analysis showed that familial factor played an important role in SYDS genesis (OR = 5.61, P = 0.001), but DM2 itself is not an independent risk factor for it. Conclusion DM2 with SYDS shows the tendency of familial aggregation and genetic predisposition, genetic factor is associated with the genesis of the syndrome. Pedigree research is a good method for exploring the relationship between syndrome and genetic factor.
