Objective To explore the relevant factors of hematoma enlargement in patients with hypertensive intracerebral hemorrhage(CH) at acute stage.Methods The clinical data of 208 patients with CH(29 patients with hematoma enlargement) were retrospectively analyzed.Results 27 cases(93.1%)of hematoma enlargement group onset at ≤ 24 h after CH.Compared with non-hematoma enlargement group,systolic blood pressure in the hematoma expansion group was significantly increased;and the rates of Glasgow coma scale(GCS) score decreased,basal ganglia hemorrhage,hepatic dysfunction,long-term alcohol drinking,taking Aspirin and diabetes in hematoma expansion group were significantly higher than those in the non-hematoma enlargement group(P

By measuring the absolute weight and growth index of the bursa of Fabricius and using routine H.E method,the growth and histological development of the bursa in 1 to 49 days duckling were studied.The results showed that the absolute weight of the bursa increased as the ducklings grew.The growth index of the bursa reached its peak at 21 days.The height and width of both the large plica and projection formed by the follicle-associated epithelium(FAE)enlarged gradually,the same as the lymphoid follicle area and cortex width.The results indicated that the bursa of Fabricius in duckling develops slowly from 1 to 14 days,and quickly from 14 to 35 days(especially from 21 to 28 days),then steadily from 35 to 49 days.Histologically,the duckling bursa has approached its maturation by the 28th day.

One hundred and seventeen patients with newly diagnosed autoimmune thyroid diseases(AITDs)and 30 normal controls(NCs)were selected.All the patients were divided into 5 groups:hyperthyroidism group(n=33),subclinical hyperthyroidism group(n=21),hypothyroidism group(n=25),subclinical hypothyroidism group(n=23)and euthyroidism group(n=15).Plasma malondialdehyde(MDA),superoxide(SOD)and inflammatory factors levels were measured.Our results showed that plasma MDA level in dysthyroidism groups was significantly higher than that in NCs group(P＜0.05 or P＜0.01).SOD/MDA ratio in AITD groups Was significantly lower than that in NCs group(P＜0.05 or P＜0.01).In a multiple step-wise regression analysis,serum hishly sensitive C-reactive protein(hs-CRP)and tumor necrosis factor-α(TNF-α)were independent factors of MDA.This study might suggest that plasma MDA level in AITD patients receiving no treatment may increase.MDA may be correlated with hs-CRP or TNF-α levels.

Objective To investigate the relationship between oxidative stress and lipid metabolism characteristics in elderly patients under different status of thyroid function. Methods Eighty-six newly-diagnosed elderly patients with thyroid diseases,83 non-elderly patients with thyroid diseases and 20 normal subjects as control were selected.and 47 hyperthyroidism and 39hypothyroidism in elderly,43 hyperthyroidism and 40 hypothyroidism in non-elderly were diagnosed according to diagnostic criteria of the thyroid disease.The levels of fasting plasma malondialdehyde(MDA),superoxide(SOD)and oxidized low density lipoprotein(OX-LDL)were measured by thiobarhiturates,colorimetric method and enzyme linked immunosorbent assay(ELISA).Meanwhile,lipid profile and thyroid function were also measured,SOD/MDA ratio was calculated. Results Lipid profiles in the elderly hyperthyroidism group were significantly higher than those in the non-elderly group(P＜O.05 or P＜0.01)but were significantly lower than those of normal control group(P＜0.05 or P＜0.01).The plasma MDA[(10.23±6.29)μmol/L vs.(3.66±2.53)μmol/L vs.(7.37±4.58)μmol/L],free fatty acids(FFA)[(0.86±0.58)mmol/L us.(0.45±0.12)mmol/L vs.(0.61±O.46)mmol/L]and SOD levels were significantly higher in elderly patients with hyperthyroidism than in normal control and non-elderly hyperthyroidism groups(P＜0.05 or P＜O.01).In the patients with hypothyroidism,the plasma MDA[(9.03±5.98)μmol/L vs.(6.59±3.18)μmol/L vs.(3.66±2.53)μmol/L],OX-LDL[(387.36±71.04)μg/L vs.(355.22±45.01)μg/L vs.(324.53±56.19)μg/L],TC,LDL-C,non-HDL-C,LP(a) and Apo-B100 levels were significantly higher in the elderly group than in the non-elderly and normal control groups(P＜0.05 orP＜0.01).The SOD/MDA ratio was significantly lower in the elderly patient groups with hyperthyroidism or hypothyroidism than in normal control and non-elderly groups(all P＜0.01).In a multiple step-wise regression analysis.FT4 and FFA were independent factors related tO MDA in hyperthyroidism group,and non-HDL-C and LDL-C were independent factors related to MDA inhypothyroidism group. Conclusions Serious lipid metabolic disorder exists in newly-diagnosed and untreated elderly patients with hyperthyroidism and hypothyroidism.It is suggested that oxidative stress is obviously strengthened in elderly patients with thyroid function disorder and that the degree of oxidative stress is correlated with lipid metabolic disorder.

Objective To detect and investigate the expression and the effect of Prohibitin (PHB) in rats with renal interstitial fibrosis (RIF) induced by unilateral ureteral obstruction (UUO) .Methods Forty-eight Wistar male rats (6-weeks-old) were randomly assigned into 2 groups,sham-operated and model group.The model group rats were subjected to left ureteral ligation after anesthesia and the sham-operated group rats were subjected to sham operation.Six rats were killed 7,14,21,28 days after operation respectively.The renal tissues were collected.The index of RIF was calculated.The expressions of mRNA and protein of PHB were assayed by real time polymerase chain reaction and immunohistochemistry. Results Compared with sham-operation group,at each time point,the model group had significantly increased index of RIF (P < 0.01) and the obstruction for a longer period showed the higher index; the model group had significantly decreased expression of mRNA and protein of PHB (P < 0.01) and the obstruction for a longer period showed the lower expression; the model group had significantly increased expression of mRNA and protein of TGF-β1 (P < 0.01) and the obstruction for a longer period showed the higher expression.Correlation analysis showed that the index of RIF was negatively correlated with FHB (γ = -0.825) and positively correlated with TGF-β1 (γ = 0.995),while there was a positive correlation between PHB and TGF-β1 (γ = -0.786).Conclusions The lower expression of PHB in renal tissue of UUO rats might suggest that it play an important role in RIF.

OBJECTIVETo investigate two polymorphism sites of exon 4 in T cells, immunoglobulin domain and mucin domain protein-1 (TIM-1, also human hepatitis A virus cellular receptor-1) and to detect whether they are associated with allergic asthma in children of the Hans in Hubei province of China.

METHODSThe ins/del and IVS 8+9 G/A polymorphisms in TIM-1 were detected with polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The genotypes and alleles frequencies were calculated and analyzed.

RESULTS(1) Two alleles, a wide type del and a variant allele ins were identified in the TIM-1 exon 4. The genotype frequencies of ins/ins, ins/del, and del/del were 0.065,0.326, and 0.608 respectively in the healthy population of the Hans. Another IVS 8/9 G/A polymorphism was also found. The genotype frequencies of A/A, G/A, G/G were 0.022, 0.196 and 0.783, respectively. (2) The genotype frequencies of ins/ins, ins/del, and del/del were 0.045, 0.318, and 0.636 respectively in the allergic asthma population in children of the Hans. No significant difference in ins/del polymorphism was found between allergic asthma patients and control subjects. Another 8/9 IVS G/A polymorphism was also found. The genotype frequencies of A/A, G/A and G/G were 0.009, 0.209 and 0.782 respectively in allergic asthma. No significant difference in IVS G/A polymorphism was found between allergic asthma patients and control subjects.

CONCLUSIONThe genotype and allele frequencies in the two polymorphism sites in TIM-1 in healthy population of the Hans from Hubei province of China were similar to those in Japanese. The two polymorphism sites of TIM-1 are not associated with allergic asthma in Chinese children.

This study was aimed to establish an experimental mouse model of combined transgenic inhibition of both multifunctional Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) and inward rectifier potassium current (Ik1), and to observe whether the specific inhibition of both CaMKII and Ik1 can bring about any effects on cardiac remodeling. Mice were divided into 4 groups: wild type (WT), CaMKII inhibited (AC3-I), Ik1 inhibited (Kir2.1-AAA) and combined inhibition of both CaMKII and Ik1 (AC3-I+Kir2.1-AAA). Mice in each group received electrocardiogram (ECG) and echocardiography examination. ECG in the condition of isoproterenol (ISO) injection was also checked. The whole cell patch clamp technique was used to measure Ik1 and the transient outward potassium current (Ito) from enzymatically isolated myocytes of left ventricle. In the condition of basal status, no significant changes of heart rate, PR interval and QRS interval were observed. No mouse showed ventricular arrhythmias in all of the 4 groups. After ISO injection, each group presented no significant ventricular arrhythmias either. The indexes measured by M-mode (motion-mode) and two-dimensional echocardiography had no significant differences among the four groups. Ik1 in AC3-I group was significantly higher than those in other three groups (P < 0.01) because of the results brought about by CaMKII inhibition. Among the latter three groups, both Kir2.1-AAA group and AC3-I+Kir2.1-AAA group had a significant reduced Ik1 compared with that of WT group, which was due to the Ik1 inhibition (P < 0.01). Ito in AC3-I group was higher than that of the other three groups (P < 0.01), but there were no significant differences in Ito among WT, Kir2.1-AAA and AC3-I+Kir2.1-AAA groups. Thus, combined transgenic myocardial CaMKII and Ik1 inhibition eliminated the up-regulation of Ik1 in CaMKII inhibited mice, and had no effects on cardiac remodeling including heart structure and function as well as arrhythmias at the basic and ISO conditions. The results of this study may provide a basis for the further investigation of combined inhibition of CaMKII and Ik1 in pathogenic cardiac remodeling.
