Objective:To observe the clinical efficacy and adverse reactions of paroxetine combined with olanzapine in the treat-ment of depression complicated with sleep disorders. Methods: Totally 150 cases of sleep disorder patients were selected, and then randomly divided into the control group and the observation group with 75 ones in each. The control group was given paroxetine treat-ment, the observation group was given paroxetine combined with olanzapine treatment, and the treatment course was four weeks. The sleep latency, total sleep time, wake-up time and the number of awakening in the two groups were recorded, and the HAMD scale score and treatment efficacy were compared. Results:Compared with those in the control group, the sleep latency, total sleep time, wake-up time and the number of awakening in the observation group were obviously improved (P<0. 05). The clinical cure rate, the HAMD scale score and the incidence of adverse reactions between the two groups all had significant differences (P<0. 05). Conclu-sion:Paroxetine combined with olanzapine in the treatment of depression with sleep disorders shows fast efficacy, which can improve the sleep disorder symptoms and reduce the incidence of adverse reactions significantly.

Objective To investigate the clinical manifestation and diagnosis of Hashimoto thyroiditis (HT). Methods 45 HT patients diagnosed by fine needle aspiration cytology (FNAC) were enrolled in this study. Their medical history, clinical parameters, data of laboratory examination, colour doppler ultrasonic image and FNAC were analyzed. Results This disease was more common in women than in men, and most of cases occurred during 35～50 years old. Almost all cases had the symptoms of thyromegaly and laryngopharynx malaise. The patients had normal thyroid function, hypothyroidism or hyperthyroidism. The levels of both antithyroid globulin antibody and antithyroid microsome antibody increased in 39 cases. The ultrasonic imaging features of thyroid were such as following: diffusive nonhomogenous hypoecho pattern in 19 cases, numerous hypoecho micronodes in 15 cases, hyperecho micronodes in 3 cases, and hyperecho bandlike echo pattern with swelling of neck lymph nodes in 8 cases. Conclusion Diagnosis of HD should put emphasis on a complete medical history, physical examination and necessary laboratory tests. Antithyroid auto-antibody assay and thyroid ultrasonic examination were very important for diagnosis of HD, and FNAC may be indispensable in suspected cases.

Objective To evaluate the association of Smad2/3,Smad4 and P-Smad3 protein expressions in tissue with liver fibrosis in patients with chronic HBV infections.Methods Liver biopsy was performed to determine the liver fibrosis grades in 131 cases of chronic HBV infections.Immunohistochemistry and semiquantitative analysis were applied to detect the expression of Smad2/3,Smad4 and P-Smad3 proteins in liver tissues.Results Smad2/3,Smad4 and P-Smad3 were detected mainly in fibrous septum,portal areas,myofibroblasts,sinus and cytoplasm in the liver tissue.The expression of Smad2/3,Smad4 and P-Smad3 was increased with the development of fibrosis ( r =0.81,0.58and 0.68,P =0.000),and a strong positive correlation was observed among three proteins (r =0.75,0.87and 0.84,P =0.000).Conclusion The expression of Smad2/3,Smad4 and P-Smad3 is correlated with liver fibrosis in chronic HBV infection,which suggests that the up-regulation of Smad proteins may be involved in the progression of liver fibrosis.

ObjectiveTo test the expression of epidermal growth factor-like domain 7 (EGFL7),microvessel density (MVD) and foeal adhesion kinase pY397 (FAKpY397) in human glioma tissues,and to evaluate their relationship.MethodsThe expression of EGFL7 and FAKpY397 in 56 cases of human glioma and 8 cases of normal brain tissues were detected by immunohistochemistry test,and MVD was detected by CD34 staining.ResultsThere was a significant difference of the positive rates of EGFL7 between normal brain tissue (0) and gliomas (75％),χ2 =17.45,P ＜0.01.With the increased pathological grade,the expression level of EGFL7 increased (χ2 =26.24,P ＜ 0.01 ).There was a significant difference of the positive rates of FAKpY397 between normal brain tissue ( 12.5％ ) and gliomas (73.2％),χ2 =6.23,P ＜ 0.05.With the increased pathological grade,the expression level of FAKpY397 increased (χ2 =6.71,P ＜ 0.01 ). MVD on normal brain was( 15 ± 4 )/HP,on Ⅰ - Ⅱ grade and Ⅲ -Ⅳ grade gliomas was ( 27 ± 3 )/HPand ( 60 ± 4 )/HP respectively,there was a significant difference on MVD between normal brain tissue and gliomas (P ＜ 0.01 ).Higher level of MVD was found in gliomas with higher grade ( P ＜ 0.01 ).There was a positive correlation between EGFL7 and FAKpY397 expressions in gliomas (r =0.314,P ＜0.01 ).There was a significant difference on MVD between positive and negative expression of EGFL7 ( t =26.55,P ＜ 0.01 ). MVD was (56 ± 4 )/HP and (25 ± 3 )/HP respectively.ConclusionThe expression of EGFL7 of human gliomas has a favorable positive correlation with the degree of malignancy,MVD and FAKpY397.It is indicated that EGFL7not only palys an important regulative role in glioma neovascularization,but also it may participate directly in glioma occurrence and invasion.

This study examined the effect of small interfering RNA-mediated β-catenin knockdown on the survival, invasion and chemosensitivity of human osteosarcoma cells (U2-OS cells). The siRNA against β-catenin was constructed and transfected into U2-OS cells. The expression of β-catenin was detected by qRT-PCR and Western blotting. Cell growth and apoptosis was detected in the presence or absence of doxorubicin by MTT and flow cytometry, respectively. Cell invasion ability was measured by transwell assay. The results showed that the transfection of β-catenin siRNA resulted in decreased expression of β-catenin, suppression of invasion and motility of U2-OS cells, reduced chemosensitivity to doxorubicin in vitro, and little change in cell growth and apoptosis. Additionally, down-regulated MT1-MMP expression was found after transfection. It was concluded that knockdown of β-catenin gene may decrease the invasive ability of human osteosarcoma cells through down-regulated MT1-MMP expression, and the chemosensitivity of osteosarcoma cells against doxorubicin.

Objective To investigate the clinical significance of CD55,CD59 and Aeromonas hydrophila toxin variant (FLAER) in the diagnosis of anemia and paroxysmal nocturnal hemoglobinuria (PNH).Methods Collected 30 healthy controls,22 cases of PNH,33 cases of aplastic anemia (AA),37 cases of iron deficiency anemia (IDA),45 cases of megaloblastic anemia (MA),30 cases of hemolytic anemia (HA) and 31 cases of myelodysplastic syndrome (MDS) from January 2009 to March 2017,CD55,CD59 and FLAER negative cell ratio of peripheral blood neutrophil of them were detected by multipa rameter flow cytometry.Results The detection rates of FLAER in PNH,AA and MDS groups were higher than those of CD55 and CD59,but there was significant difference in AA (x2 =7.759,5.518,P=0.005,0.019＜0.05).The average CD55,CD59 and FLAER deletion rate in PNH and AA group were significantly higher than those in normal control group and other groups (t=2.163～17.890,P=0.000～0.038＜0.05).The number of FLAER in PNH group was higher than CD59 and CD59 was higher than CD55 with the statistically significant difference (t=2.503 ～ 6.308,P=0.000 ～0.016＜ 0.05).Conclusion CD55,CD59 and FLAER have important value in the diagnosis of PNH and differential diagnosis with other anemia diseases,and can also be used to detect the presence of MDS and AA in patients with PNH.FLAER outperforms CD59,CD59 outperforms CD55.

Objective To study the clinical features and angiographic findings of moyamoya disease (MMD) as well as their relationship. Methods A total of 22 MMD patients received routine digital substraction angiography (DSA). The clinical manifestations and angiographic findings were analyzed. Results Clinical manifestations varied and each patient often had multiple symptoms, including cerebral infarction in 9 patients with an average age of 23.6 (13-39 years) and cerebral hemorrhage in 7 patients with an average age of 31.2 (28-46 years). Angiographic examination found that all the diseased sides showed MMD blood vessels. The patients who received encephalo-myo-arterio-synangiosis (EMAS) had better prognosis than those without receiving the treatment. Conclusion Cerebral infarction is frequent in children and adolescents with MMD, whereas cerebral hemorrhage is common in adults. DSA is a golden criterion for diagnosing MMD. Surgical treatment, EMAS blood supply reconstruction in particular, should be prescribed.

Objective To investigate the effects of edaranvone on lung injury induced by myocardial ischemia-reperfusion (I/R) in rats. Methods Twenty-four male Wistar rats weighing 250-300 g were randomly assigned to one of 4 groups ( n = 6 each): group Ⅰ sham operation (group S); group Ⅱ myocardial I/R and group Ⅲ and Ⅳ different doses of edaravone ( group E1, E2 ). The animals were anesthetized, intubated and mechanically ventilated. In group Ⅱ-Ⅳ myocardial I/R was induced by occlusion of left anterior descending coronary artery for 45 min followed by 3 h reperfusion. In group Ⅲ and Ⅳ edavarone 3 and 10 mg/kg was administered via right femoral vein at 1 min before reperfusion respectively. The animals were sacrificed by exsanguination at the end of 3 h reperfusion. Blood was collected for determination of serum CK-MB activity and total protein content. The left lung was lavaged and the broncho-alveolar lavage fluid (BALF) was colleted for determination of protein content. Pulmonary permeability index (PPI) was calculated. The lung tissue was obtained for determination of BD-2 mRNA and protein and TNF-α expression. Results The serum CK-MB activity, PPI,BD-2 mRNA and protein and TNF-α expression were significantly higher in group I/R, E1 and E2 than in group S,but significantly lower in group E1 and E2 than in group I/R and in group E2 than in group E1. Conclusion Edaravone can reduce myocardial I/R-induced lung injury by scavenging oxygen free radicals and inhibiting inflammatory response of lung tissues in rats.
