ObjectiveTo observe the effect of early rehabilitation on poststroke anxiety and depression.Methods137 stroke patients with hemiplegia were divided into the rehabilitation group (70 cases) and control group (67 cases). All patients in both two groups were given routine clinical treatment, but the patients in the rehabilitation group were given regular early rehabilitation. All patients were evaluated with Bathel Index (BI), Fugl-Meyer Motor Scale (FMMS), Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) before and 3 months after treatment.ResultsAfter 3 months treatment, the scores of HAMD, HAMA, BI and FMMS of patients in the rehabilitation group increased significantly compared with those before treatment ( P<0.05～0.01), and those in the control group ( P<0.05). The scores of BI and FMMS of patients in the control group after treatment also increased significantly compared with those before treatment ( P<0.05). The incidences of depression and anxiety of the rehabilitation group were 22.86% and 5.71%, those of the control group were 40.30% and 16.42%, there was a significant difference between two groups( P<0.05).ConclusionThe early rehabilitation can obviously decrease anxiety and depression of stroke patients with hemiplegia.

OBJECTIVE: To study the absorption characteristics of allicin in rat intestinal tract.METHODS: An HPLC method was established to determine the content of allicin in rat entericus, and Ussing chamber system was used to investigate the absorption characteristics of garlic spicy element of different concentrations in the duodenum, jejunum, ileum and colon of rats. RESULTS: An HPLC method was established to determine the content of allicin in rat intestinal liquid.The absorption rate constants of allicin in various intestinal segments of rats in the experimental concentration range increased with the increase of allicin concentration.Allicin showed linear absorption in different intestinal segments of rats, with regression correlation coefficients of greater than 0.96, indicating zero order absorption. CONCLUSION: Allicin has different absorption characteristics in different intestinal segments of rats and can be absorbed as prototype.

OBJECTIVETo study the impacts of exposure to electromagnetic radiation (EMR) on liver function in rats.

METHODSTwenty adult male Sprague-Dawley rats were randomly divided into normal group and radiated group. The rats in normal group were not radiated, those in radiated group were exposed to EMR 4 h/ d for 18 consecutive days. Rats were sacrificed immediately after the end of the experiment. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and those of malondialdehyde (MDA) and glutathione (GSH) in liver tissue were evaluated by colorimetric method. The liver histopathological changes were observed by hematoxylin and eosin staining and the protein expression of bax and bcl- 2 in liver tissue were detected by immunohistochemical method. Terminal-deoxynucleotidyl transferase mediated nick and labelling (TUNEL) method was used for analysis of apoptosis in liver.

RESULTSCompared with the normal rats, the serum levels of ALT and AST in the radiated group had no obvious changes (P>0.05), while the contents of MDA increased (P < 0.01) and those of GSH decreased (P < 0.01) in liver tissues. The histopathology examination showed diffuse hepatocyte swelling and vacuolation, small pieces and focal necrosis. The immunohistochemical results displayed that the expression of the bax protein was higher and that of bcl-2 protein was lower in radiated group. The hepatocyte apoptosis rates in radiated group was higher than that in normal group (all P < 0.01).

CONCLUSIONThe exposure to 900 MHz mobile phone 4 h/d for 18 days could induce the liver histological changes, which may be partly due to the apoptosis and oxidative stress induced in liver tissue by electromagnetic radiation.

OBJECTIVETo study the effect of nano-SiO2 on spatial learning and memory.

METHODSTwenty-four male rats were randomly divided into 3 groups: control group (C group), low dose group (L group) and high dose group (H group). The rats were intragastrically administrated with nanometer particles at 25 and 100 mg/kg body weight every day for 4 weeks. After exposure, the ability of learning and memory of rats was tested by Morris water maze, and electrophysiological brain stereotactic method was used to test long-tear potentiation (LTP) in dentate gyrus (DG) of the rats.

RESULTSThe increase rate of body weight in H group was reduced significantly compared with C group ( P < 0.05). In the space exploration experiment of Morris water maze test, the escape latency of H group was longer than that of C group (P < 0.05). The rats of H group spent less time in finding the target quadrant (P < 0.05) . The rate of LP induction of H group was significantly lower than that of C group (P < 0.05). After high fre quency stimulation (HFS), The changes of amplitude of population spike (PS) of L group and H group were lower than those of C group significantly (P < 0.05, P < 0.01).

CONCLUSIONNano-SiO₂may result in impairment of spatial learning and memory ability by reducing the rate of LTP induction and the increase of PS in hippocampus.

Subclinical hypothyroidism during pregnancy is associated with some adverse outcomes during maternal pregnancy.The present study investigated thyroid function parameters measured by electroehemiluminescence (ECL) immunoassays in subclinical hypothyroid women treated with levothyroxine (L-T4) during pregnancy.The results showed that in evaluating thyroid function with ECL immunoassays during replacement with L-T4,determination of serum TT4 appears to have a closer correlation with TSH and may better reflect the effìcacy of treatment.

Objective To investigate the changes of serum high sensitive C-reactive protein(hs-CRP) level in patients with acute cerebral infarction(ACI),and the relationship between serum hs-CRP level and ACI severity as well as subtypes according to Chinese Ischemic Stroke Subclassification(CISS)criteria. Methods The serum hs-CRP level in 256 patients with ACI and 196 normal controls were measured. The degree of nervous function defect in patients with ACI was assessed by the United States National Institutes of Health Stroke Scale ( NIHSS ) score. All patients were classified into five major ischemic stroke subtypes based on CISS criteria. Logistic regression analysis was applied to analyze the risk factors of ACI. Results The serum hs-CRP level in patients with ACI and control group were(4. 69 ± 2. 58)mmol/ L and(2. 13 ± 1. 79)mmol/ L,and the difference between groups was significant(t = 12. 439,P = 0. 000). The hs-CRP in patients with severity ACI (147 cases)were(5. 89 ± 4. 15)mmol/ L,significantly higher than that in patients with mild ACI,and the difference between groups was significant((2. 11 ± 1. 45)mmol/ L,t = 10. 230,P = 0. 000)). As for subtype ACI,the case of the large artery atherosclerosis subtypes was 106( 41. 57% ),highest than any other subtypes. The hs-CRP level of large artery atherosclerosis was(7. 01 ± 3. 12)mmol/ L,higher than that of control group( P = 0. 000). The logistic regression analysis showed that many factors were related to ACI including total cholesterol,homocysteine and high sensitive C-reactive protein( OR = 0. 324,0. 749,0. 809;P< 0. 05). Conclusion The serum hs-CRP level in patients with ACI increase significantly,and relate to the degree of neural function defect. The level of hs-CRP of large artery atherosclerotic stroke is the highest. The change of serum hs-CRP is very valuable to estimate the severity of ACI.

Objective To investigate the expressions and significances of Bcl-2 and Bax in basal-like breast carcinoma (BLBC).Methods The expressions of Bcl-2 and Bax were detected in 43 cases of BLBC, 57 cases of non-BLBC and 60 cases of normal breast tissues by immunohistochemistry,and their relationships with physiological and pathological characteristics of patients were analysized.Results The positive rate of Bcl-2 in BLBC was 69.77%,higher than 43.86% in non-BLBC (χ2 =6.647,P =0.01 0)and 21 .67% in normal breast tissues (χ2 =23.831 ,P =0.001 ).The positive rate of Bax in BLBC was 20.93%,lower than 45.61 % in non-BLBC (χ2 =6.564,P =0.01 0)and 76.67% in normal breast tissues (χ2 =31 .270,P =0.001 ).The expressions of Bcl-2 and Bax were correlated with lymphnode metastasis (χ2 =6.927,P =0.008;χ2 =6.203,P =0.01 3)and pTNMstaging of BLBC (χ2 =6.331 ,P =0.01 2;χ2 =5.972,P =0.01 5).There was negative correlation between the expression of Bcl-2 and Bax in BLBC (r = -0.408,P <0.01 0). Conclusion High expression of Bcl-2 and low expression of Bax interact with each other leading to unbalance of cell deferation and apoptosis,resulting in promoting genesis and progress of BLBC.

Objective At present, there are few studies about myelolipoma within adrenal cortical adenoma.Our aim was to provide more basis for correct diagnosis and treatment by investigation into its clinical and pathological features.Methods The clinical and pathological data were retrospectively reviewed in 11 patients of myelolipoma within adrenal cortical adenoma, along with relative literature reviews.Results The median age of 11 patients (7 females, 4 males) was 49±9.5 years, among whom 3 patients presented Cushing's syndrome, 1 patient with more than 10 years' recurrent dizzy with hypertension, other 7 patients were found coincidently by routine examination.Adrenal mass were found by imaging examination.Pathologically, myelolipomas were in solitary nodule distribution and/or admixed with adrenal cortical adenomas.Myelolipomas were composed of variable admixture of mature adipose tissue and hematopoietic elements.Surgical treatment was performed for all 11 patients, and no relapse was found in 2 months' to 11 years' follow-up.Conclusion Myelolipoma within adrenal cortical adenoma is extremely rare, which is common in females.The patients may present with Cushing's syndrome, hypertension or without obvious clinical syndrome.All the patients are in favorable prognosis after surgical resection.

Objective To study the levothyroxine doses and related factors in the treatment of pregnant women with subclinical hypothyroidism (SCH).Methods Fifty-six pregnant women with SCH (diagnosed before 12 weeks of gestation) were recruited and divided into 2 groups according to the baseline TSH levels,SCH group 1 (2.5 mIU/L ≤ TSH ≤ 5.0 mIU/L,n =24) and SCH group 2 (TSH＞5.0 mIU/L,n =32).Thyroid autoantibodies [thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)] were detected.All the subjects were treated with levothyroxine and the doses were adjusted according to the TSH level.The therapeutic target was to keep the TSH levels under control,0.3 to 2.5 mIU/L for the first trimester and 0.3 to 3.0 mIU/L for the second and third trimesters.Results There was a positive correlation between the levothyroxine doses and baseline TSH levels (r =0.533,P＜0.01) in pregnant women with SCH.A significant difference in the levothyroxine doses between SCH group 1 and SCH group 2 was found [(0.583 ± 0.341) vs (0.961 ± 0.405) μg/kg,t =-3.695,P＜ 0.01].The levothyroxine doses in SCH group 2 were 64.84％ higher than those in group 1.There was a significant difference in the levothyroxine doses between thyroid autoantibody negative and positive subjects [(0.680 ± 0.370) vs (0.918 ±0.440) μg/kg,t =-2.197,P =0.032].The levothyroxine doses in thyroid autoantibody positive subjects were 35 ％ higher than those in the negative subjects.In addition,there was a significant difference in the levothyroxine doses between subjects with negative and positive thyroid autoantibody [(0.421 ± 0.192) vs (0.720 ± 0.385)μg/kg,t =-2.331,P =0.029] in SCH group 1.While in SCH group 2,the difference did not reach statistical significance.Conclusion The baseline TSH levels and status of thyroid autoantibodies may affect the levothyroxine dosage in pregnant women with SCH.
