Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

Objective To improve the recognition of intramedullary spinal abscess by a case of congenital dermal sinus with intramedullary spinal abscess and reduco the incidence of congenital dermal sinus with intramedullary spinal abscess.Methods Clinical,laboratory data and image of a confirmed case about one infant of congenital dermal sinus with multiple intramedullary spinal abscess were investigated,the related literature was reviewed.Results In this case,when the infant with congential dermal sinus had infection,he failed to gain antibiotic therapy, timely surgical treatment,his infection had diffused, and multiple intramedullary spinal abscess flared up.Conclusions Intramedullary spinal abscess is a rare disease.If treatment is delayed, the prognosis is poor and the mortality rate is high.MRI is the ideal investigation for diagnosis.Intramedullary spinal abscess can happen subsequent to congenital dermal sinus with infection, and cause neurological sequela. So an infant with congenital dermal sinus should be offered to avoid complication caused by infection.

Objective To investigate the association between essential hypertension(EH)and nonalcoholic fatty liver(NAFL).Methods Four hundred and nine patients of EH underwent liver uhrasonographic examina- tion during 2006-2007 year were enrolled.Patients were categorized as MS(n=312)or non-MS(n=97)ac- cording to the criteria by CDA.Body mass index(BMI),blood pressure,the profiles of blood lipid,liver func- tion,renal function,plasma sugar were determined.Results 1)The prevalence of fatty liver in EH+MS group (66.0%)was significantly higher than that of EH without MS group(41.2%,P

Objective This study aimed to explore the epidemiological characteristics and related factors of overweight and obesity in Tianjin adults. Methods With multi-stage randomized cluster sampling, 19 271 people aged 18 years and over were selected from both urban and rural areas of six geographical regions of Tianjin in 2006, using a cross-sectional methodology. Data from these residents was collected, using a questionnaire by face-to-face interview conducted by trained interviewers. Demographic, anthropometric data were collected in all participants. Data was analyzed with SPSS 13.0 software. For diagnosis of overweight and obesity, we adopted the standard of overweight and obesity recommended for Chinese adults. Age, gender and area distribution of overweight and obesity in the population of Tianjin were described, and the related factors were analyzed. Results Prevalence of overweight and obesity in adults from Tianjin were 32.8%(95%CI: 32.1%-33.5%) and 11.7% (95% CI: 11.2%-12.2%), with the standardized rates as 33.1% and 12.2%, respectively. Those figures were higher than the national average levels. The prevalence rates of overweight and obesity were increasing with age. The overweight rate in 50-59 year olds and the obesity rate in 60-69 year olds reached their peak values. The prevalence rate of obesity was higher in rural (13.5%,with 95%CI: 12.8%-14.2%) than in the urban areas (11.1%,with 95%CI: 10.4%-11.7%) and in females (12.6%,95%CI: 11.9%-13.2%) than in males (10.9%,95%CI: 10.3%-11.5%). Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Tianjin were statistically associated with age, gender, educational level, smoking, alcohol consumption and exercises. Conclusion As the urbanization progressing, the prevalence of overweight and obesity was much higher in the population of Tianjin city. Many factors were related to adults overweight and obesity. An active community-based public health intervention should be taken.

OBJECTIVE Programmed death ligand-1 (PD-L1) and indoleamine 2, 3-dioxygenase 1 (IDO1) are immune checkpoints which can be induced by interferon-γ(IFN-γ) in the tumor microenvironment, leading to immune escape of tumors. Myricetin (MY) is a flavonoid distributed in many edible and medicinal plants. The aim of this study is to clarify the effect and the mechanism of MY on inhibiting IFN-γ-induced PD-L1 and IDO1 in lung cancer cells. METHODS Expressions of PD-L1 and major histocompatibility complex-I (MHC-I) were evaluated by flow cytometry and Western blotting, and the expression of IDO1 was measured by Western blotting. qRT-PCR was used to detect their mRNA levels. The function of T cells was evaluated using a co-culture system consist of lung cancer cells and the Jurkat-PD-1 T cell line that overexpressing PD-1. Molecular docking analysis, Western blotting and immunofluorescence were used for mechanism study. RESULTS MY potently inhibited IFN-γ-induced PD-L1 and IDO1 expression in human lung cancer cells, while didn't show obvious effect on the expression of MHC-I. In addition, MY restored the survival, proliferation, CD69 expression and interleukin-2 (IL-2) secretion of Jurkat-PD-1 T cells suppressed by IFN-γ-treated lung cancer cells in the co-culture system. Mechanistically, IFN-γ up-regulated PD-L1 and IDO1 at the transcriptional level through the JAK-STAT-IRF1 axis, which was targeted and inhibited by MY. CONCLUSION Our research revealed a new insight into the anti-tumor effects of MY which inhibited IFN-γ-induced PD-L1 and IDO1 expression, supporting the potential of MY in anti-tumor immunotherapy.

This study is to investigate the protective effect of longistyline A against corticosterone-induced neurotoxicity in PC12 cells. While PC12 cells were exposed to 100 micromol x L(-1) corticosterone for 48 h, cell survival rate was reduced and lactate dehydrogenase (LDH) release increased. In parallel, corticosterone caused significant elevations of DNA fragmentation, [Ca2+]i and caspase-3 activity. However, when the PC12 cells were incubated with longistyline A (4.0, 8.0 and 16.0 micromol x L(-1)) in the presence of 100 micromol x L(-1) corticosterone for 48 h, the effects were evidently alleviated, but dose-dependent manner was not obvious. In summary, longistyline A could generate a neuroprotective effect against corticosterone-induced neurotoxicity in PC12 cells possibly by decreasing [Ca2+]i and caspase-3 activity.

Objective To analyze the epidemiological characteristics and trends of accidental death among children under 5 in Wenzhou during the period of 2007—2016, and to provide basis for the intervention program of accidental death in children. Methods The accidental death case of children in Wenzhou during 2007—2016 were collected,then the variation intensity, trend, and cause of death spectrum of accidental death were analyzed. Results The accidental death rate of children under 5 in this city showed a downward trend (P<0.05) during 2007—2016, with 12.38 per ten thousand on average. The accidental death rate of children in rural area was 13.26 per ten thousand, which was higher than 9.99 per ten thousand in urban area (P<0.05) . The accidental death gap between urban and rural children was narrowed down (P<0.05) . The unintentional death rate of floating children was 18.56 per ten thousand, and was higher than that of local children which was 9.44 per ten thousand (P<0.05) . The first cause of accidental death in children under 5 was accidental asphyxia, but drowning (46.38%) was more prominent in the 1-4 year old children. Conclusion In Wenzhou, the first cause of accidental death in children under 5 was accidental asphyxia.The accidental death of migrant children was significantly higher than local children.These characteristics have a good directional effect on future intervention measures.
