OBJECTIVECoronary heart disease (CHD) is one of the most common causes of death in the world. Some studies suggested that CHD begins in childhood. Obesity and dyslipidemia are important risk factors of coronary heart disease. Apolipoprotein (apo)E gene associated with dyslipidemia and coronary heart disease. The present study was designed to investigate the expression status of apoE gene in peripheral blood monocyte and association of apoE gene expression with lipids in children with obesity.

METHODSAmong 32 children with obesity and 32 healthy children without obesity or overweight, ApoE gene expressions were determined by competitive reverse transcription-polymerase chain reaction in peripheral blood monocyte. The concentrations of plasma triglyceride, total cholesterol, low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, lipoprotein(a), apoA I, apoB(100) and apoE were measured.

RESULTSExpression of apoE gene was detected in peripheral blood monocyte. Expression of apoE gene was significantly reduced in children with obesity as compared with control group (0.29 +/- 0.14 moles/mole GAPDH mRNA vs. 0.36 +/- 0.10 moles/mole GAPDH mRNA, t = 2.15, P < 0.05). The more severe was the degree of obesity, the more significantly reduced the expression of apoE gene; the degree of obesity was negatively correlated with the levels of expression of apoE gene (correlation coefficient = -0.40, P < 0.05). Compared with control group, the levels of triglyceride, total cholesterol, low density lipoprotein-cholesterol, and apoB(100) were higher, and those of high density lipoprotein-cholesterol, apoA I and apoE were lower in children with obesity [(1.68 +/- 0.50) mmol/L vs. (0.99 +/- 0.54) mmol/L, (4.47 +/- 0.91) mmol/L vs. (3.33 +/- 0.90) mmol/L, (2.23 +/- 0.71) mmol/L vs. (1.13 +/- 0.96) mmol/L, (94.48 +/- 9.97) mg/dl vs. (83.81 +/- 15.64) mg/dl, (1.47 +/- 0.39) mmol/L vs. (1.73 +/- 0.36) mmol/L, (112.71 +/- 27.86) mg/dl vs. (134.80 +/- 45.36) mg/dl, (24.50 +/- 10.92) mg/L vs.(35.07 +/- 9.79) mg/L, respectively, P < 0.05]. ApoE gene expression was associated with plasma lipids metabolism in children with obesity. The quantity of apoE gene expression was inversely associated with low density lipoprotein-cholesterol, positively correlated with apoE (correlation coefficient = -0.33, 0.35, respectively, P < 0.05). The quantity of apoE gene expression was not associated with total cholesterol, triglyceride, high density lipoprotein-cholesterol, lipoprotein(a), apoA I, and apoB(100) (correlation coefficient = -0.19, -0.11, 0.16, 0.09, 0.18, 0.22, P > 0.05).

CONCLUSIONExpression of apoE gene was significantly reduced in peripheral blood monocyte in children with obesity. The quantity of apoE gene expression was associated with degree of obesity and abnormality of blood lipids.

Objective To investigate clinical symptoms,pathophysiology and brain imaging features of Chinese familial cerebral cavernous angiomas.Methods Head MRI examination,clinical and pathophysiological examination were performed in a Chinese family with one proband of cerebral cavernous malformation.The disease atlas of the family was drawn.The patients indicative of a surgery underwent resection of hemangioma whose pathophysiology and microstructure were observed.Results Nine familial cerebral cavernous angiomas patients were found to have multiple intracranial lesion in the 18 family members,the penetrance being 50%,conforming to the feature of autosomal incomplete dominance inheritance.Four patients with skin cavernous hemangioma had familial cerebral cavernous angiomas.MRI was the most sensitive modality for the diagnosis of cavernous angioma.With T_2-Weighted sequences,the lesion was typically characterized by an area of mixed signal intensity,with a central reticulated core and a peripheral rim of decreased signal intensity related to deposition of hemosiderin.Gradient-echo(GRE)MRI could find microcavernous hemangiomas that would not be found in other sequences.Cavernous angiomas were typically discrete multilobulated berrylike lesions that contained hemorrhage in various stages of evolution.Histological homogeneity and overlap with other vascular malformations such as capillary telangictasia was common.Cavernous angiomas were composed of endothelial-linked sinusoidal spaces not separated by significant amounts of neural tissue.Hemorrhagic residua were common.Clots at different stages of evolution within the lesion were seen.The basic membranes of sinus became thick and soft.Parts of it were layered.Conclusions Familial cerebral cavernous angiomas is an autosomal incomplete dominance inheritance disease.Cavernous angiomas are composed of endothelial-linked sinusoidal spaces not separated by significant amounts of neural tissue.There are more than one focus in every patients and the skin cavernous angiomas is the foundation of diagnosing familial cerebral cavernous angiomas.Gradient-echo imagine sequence MRI(3.0 T)could be the"golden standard".

The clinical study was conducted to further evaluation the effectiveness and safety of Fangfeng Tongsheng granule in the treatment of sub-acute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome). In the block randomized, multi-centered study, totally 108 patients were enrolled and assigned to two groups: 72 patients in the test group and 36 patients in the placebo control group. Those in the test group took Fangfeng Tongsheng granule with the dose of 3 g, twice a day, while those in the control group were give simulated agent granules with the same dose. The therapeutic course lasted for 14 days. Their efficacies in TCM syndrome, dermal symptoms and adverse events were observed. According to the test results, except for the one exit case, all of the remaining 108 cases, including 71 in the test group, and 36 in the control group, completed the clinical trial. As for the efficacy of TCM syndrome, after the medication for 2 weeks, the cure rate was 33.81% (24/71) in the test group and 0% (0/36) in the control group (P < 0.01), with a statistical difference between the two groups. Regarding the TCM score, after the medication for 2 weeks, the test group decreased by (12.82 +/- 7.96), while the control group decreased by (3.67 +/- 4.12), indicating a statistical difference between the two groups. As for the efficacy of dermal symptoms, after the medication for 2 weeks, the cure rate was 25.35% (18/71) in the test group and 0% (0/36) in the control group, with a statistical difference between the two groups. Regarding the dermal symptom score, after the medication for 2 weeks., the test group decreased by (10.04 +/- 7.17), while the control group decreased by (2.33 +/- 3.57), indicating a statistical difference between the two groups. There was no significant adverse event caused by Fangfeng Tongsheng granule. In conclusion, Fangfeng Tongsheng granule was effective and safe in treating subcute eczema (superficial cold and interior heat syndrome, exterior and interior sthenic syndrome).

OBJECTIVETo clarify the different prognostic characteristics between profound sudden sensorineural hearing loss (SSNHL) and total SSNHL.

METHODSThe patients with SSNHL who visited Eye Ear Nose and Throat Hospital from June 2007 to September 2008 were reviewed retrospectively. All the 204 patients, with pure tone average (PTA) threshold more than 90 dB, were enrolled and divided into two groups, including total SSNHL and profound SSNHL groups. The relationship between recovery rate and prognostic factors including the age, complications, time period between onset and therapy was analyzed.

RESULTSThere were 57 cases of total SSNHL and 147 cases of profound SSNHL in this series. Tinnitus was complained in more than 90% of the patients in both groups, which was higher than that of dizziness and ear fullness. Dizziness was present in 64.9% (37/57) patient with total SSNHL group and 45.6% (67/147) patients with profound SSNHL, which had significant difference between the two groups (&chi;(2) = 5.72, P = 0.017). The PTA threshold improvement in total SSNHL group and profound SSNHL group was (36.4 ± 19.3) dB and (40.2 ± 21.3) dB respectively, which was no significant difference between the two groups (t = 1.165, P = 0.245). The cured patients were all those received therapy within 1 week following the onset of SSNHL, which was of 2.6% (1/38) patients in the total SSNHL group and 14.3% (14/98) patients in the profound SSNHL group (P = 0.045). Furthermore, 3.5% (2/57) patients in total SSNHL group as well as 29.9% (44/147) patients in profound SSNHL group obtained a good result with PTA threshold ≤ 50 dB after therapy (&chi;(2) = 15.92, P = 0.001). In addition, the favorable prognosis was related with the onset-therapy time point(P = 0.001), but not related to the patients' age.

CONCLUSIONProfound SSNHL and total SSNHL though both with PTA threshold > 90 dB had significant differences recovery rate and need to be studied separately.

OBJECTIVETo investigate the efficacy and safety of the comprehensive protocol of integrative medicine in preventing and treating perioperative delayed cerebrovasospasm (DCVS) in patients with aneurysmal subarachnoid hemorrhage (aSAH).

METHODSUsing a prospective randomized controlled trial design, 63 aSAH inpatients were assigned to the treatment group (31 cases, 24 treated by intervention treatment and 7 by craniotomy) and the control group (32 cases, 26 treated by intervention treatment and 6 by craniotomy). All patients were treated with basic therapy and nimodipine. Those in the treatment group additionally took naomai jiejing decoction No. 1 and No. 2. The incidence and the mortality of DCVS, re-bleeding, hydrocephalus were compared on the 180th day. The middle cerebral artery mean flow velocity (Vm), PI value, linde-gard index on day 1, 3, 7, and 14 were compared. The Chinese medicine syndrome score, NIHSS, and revised Rankin questionnaire on day 1, 14, and 180 were compared.

RESULTSThe DCVS occurred in 9 cases (29. 0%) of the treatment group and 17 patients (53.1%) of the control group, showing statistical difference (P < 0.05). The occurrence of re-hemorrhage was obviously lower in the treatment than in the control group (3.2% vs. 6.2%), showing statistical difference (P < 0. 05). There was no statistical difference in the mortality (6.4% vs. 9.4%) or the occurrence of hydrocephalus (29.0% vs 25.0%, P > 0.05). The Vm, PI, and linde-gard index on day 7, the Vm and linde-gard index on day 14 were obviously lower in the treatment group than in the control group (P < 0.05). The Chinese medicine syndrome score and NIHSS on day 14 and 180 were lower in the treatment group than in the control group, showing statistical difference (P < 0.05).

CONCLUSIONThe comprehensive protocol of integrative medicine could reduce the incidence of aSAH patients' DCVS, the Chinese medicine syndrome score and NIHSS, and improve their clinical symptoms.

BACKGROUNDThe interleukin-1 (IL-1) receptor-associated kinase 1 (IRAK1) is believed to play an important role in the pathogenesis of sepsis. Recent studies have suggested that the IRAK1 functional genetic variant could affect the severity of sepsis in Caucasians. In this report, we have investigated whether polymorphisms at the IRAK1 gene are associated with the susceptibility to and severity of sepsis among the Chinese population.

METHODSHaplotype-tagging single nucleotide polymorphisms (htSNPs) were selected from the HapMap database. They were genotyped in 255 patients with sepsis and 260 control subjects by PCR/restriction fragment length polymorphism (RFLP) analysis. The association between the selected htSNPs and the susceptibility to and severity of sepsis were estimated by Logistic regression with adjustments for age, sex, smoking, drinking, chronic disease status, Acute Physiology and Chronic Health Evaluation (APACHE) II score and primary diseases.

RESULTSrs1059702 was selected to represent the six linked htSNPs for IRAK1. Genotype frequencies of the htSNPs were in Hardy-Weinberg equilibrium for females, as were allele frequencies for both sex groups. Associations were observed in females between the htSNPs C/C genotype and increased susceptibility to sepsis (odds ratio (OR), 5.46; 95% confidence interval (CI), 1.12 - 26.67; P = 0.018), and such associations were also observed between the IRAK1 variant haplotype (CC/C-allele) and increased susceptibility to sepsis (OR, 1.68; 95% CI, 1.05 - 2.70; P = 0.031) when compared with the T/T + T/C genotype and the wild-type haplotype (TC + TT/T-allele). In the multiple organ dysfunction syndrome (MODS) subgroup, the variant haplotype was also associated with increased severity of sepsis (OR, 2.37; 95% CI, 1.13 - 4.94; P = 0.02) when compared with the wild haplotype. This association was not significant in male patients.

CONCLUSIONSThe functional polymorphism in exon 5 and the variant haplotype of IRAK1 gene mediate susceptibility to and severity of sepsis. IRAK1 might be a genetic risk factor for the occurrence and development of sepsis in the Chinese population.

BACKGROUNDFamilial cerebral cavernous malformations (CCMs), characterized by hemorrhagic stroke, recurrent headache and epilepsy, are congenital vascular anomalies of the central nervous system. Familial CCMs is an autosomal dominant inherited disorder and three CCM genes have been identified. We report a Chinese family with CCMs and intend to explore clinical, pathological, magnetic resonance imaging (MRI) features and pathogenic gene mutation of this family.

METHODSTotally 25 family members underwent brain MRI examination and clinical check. Two patients with surgical indications had surgical treatment and the specimens were subjected to histopathological and microstructural examination. In addition, polymerase chain reaction (PCR) and direct sequencing were performed with genomic DNA extracted from 25 family members' blood samples for mutation detection.

RESULTSBrain MRI identified abnormal results in seven family members. All of them had multiple intracranial lesions and four cases had skin cavernous hemangioma. T2-weighted sequence showed that the lesions were typically characterized by an area of mixed signal intensity. Gradient-echo (GRE) sequence was more sensitive to find micro-cavernous hemangiomas. There was a wide range in the clinical manifestations as well as the age of onset in the family. The youngest patient was an 8-year-old boy with least intracranial lesions. Histopathological and microstructural examination showed that CCMs were typically discrete multi-sublobes of berry-like lesions, with hemorrhage in various stages of illness evolution. They were formed by abnormally enlarged sinusoids and the thin basement membranes. A novel T deletion mutation in exon 14 of CCM1 gene was identified by mutation detection in the seven patients. But unaffected members and healthy controls did not carry this mutation.

CONCLUSIONSThe clinical manifestations were heterogenic within this family. We identified a novel mutation (c.1396delT) was the disease-causing mutation for this family and extended the mutational spectrum of CCMs.
