Objective To explore predictive value of spectra parameter changing of transcranial Doppler (TCD) for intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in patients with intracranial infection. Methods TCD examination was taken before 128 times of lumbar puncture for pressure testing in 42 patients with intracranial infection. Meanwhile, Data of TCD and cerebrospinal fluid (CSF) pressure were recorded for later analysis and compared with control group.Results With ICP increase progressively , the TCD of above patients showed high resistance spectra, waveform sharpened, peak systolic velocity (Vs) without significant change while in end diastolic velocity (Vd) decreased and pulsatility index (PI) increased.Compared with control group, their blood flow velocity significantly increased.According to the TCD parameter and stepwise regression equations, predicted ICP and CPP ( ICPe and CPPe) were positive correlated with actual ICP and CPP (r=0.594,0.910, allP

Objective To compare the characteristics of MRI, CT, single photon emission computed tomography(SPECT) and transcranial Doppler sonography(TCD) in patients with spongiform leukoencephalopathy after inhaling heroin vapor. Methods Seventeen patients were investigated. MRI or CT was scanned in 17 patients, SPECT in 9 patients′ and TCD in 11 patients. Results MRI or CT: Brain MRI and CT revealed extensive symmetric white matter involvement of bilateral cerebral and cerebellar hemispheres and the brainstem.The lesions, which showed no contrast enhancement, were hypodense on CT and hypointense on T 1 weighted and hyperintense on T 2 weighted MRI. SPECT: The regional cerebral blood flows(rCBF) of white matter involvement on bilateral cerebral and cerebellar hemispheres was reduced obviously. The rCBF of temporal lobes, parietal lobes, occipital lobes, cerebellar hemispheres, and basal ganglion was reduced in varying degrees. TCD: The systolic peak became sharpened, and end diastolic flow velocity and mean flow velocity were reduced obviously and pulsatility index was increased markedly in patients with spongiform leukoencephalopathy after inhaling heroin vapor. Conclusion The characteristic manifestations of MRI and CT imaging may be regarded as the main foundation of diagnosing spongiform leukoencephalopathy after inhaling heroin vapor; SPECT and TCD can help comprehend the changes of hemodynamics of cerebral vessels and the degree of cerebral ischemia in patients with spongiform leukoencephalopathy after inhaling heroin vapor.

[Summary] With the improvement of current medical diagnosis and treatment technology, more and more patients with adrenal hypoplasia congenita and hypogonadotropic hypogonadism have been diagnosed. DAX-1 gene mutation has been accounted for one of the most important reasons. Clinical manifestations include adrenocortical hypofunction such as loss of salt, dehydration, nausea and vomiting, as well as gonad dysplasia of male patients in puberty. The disease can be diagnosed by blood biochemical and hormonal level testings, imaging tests and gene sequencing. Patients can be treated by glucocorticoid, mineralocorticoid, and male sex hormone. The review will expand the diagnosis and treatment of adrenal hypoplasia congenita with hypogonadotropic hypogonadism caused by DAX-1 gene mutation.

Objective:To study the possible role of LPS and IL-13 on IL-12 production of mesangial cells in vitro.Methods:The production of IL-12 in mesangial cells was detected with ELISA kit under following different treatments:①Mesangial cells were cultured with LPS(20 ?g/ml)under different time;②The cells were cultured with different concentrations of LPS for 24 h.For observation of the effect of IL-13 on IL-12 production by mesangial cells,three groups were designed:control group,LPS(10 ?g/ml)group and different concentrations of IL-13 with LPS (10 ?g/ml).ELISA was applied to detect IL-12 in supernatants fluid from mesangial cells cultured for 24 h.The expression of IL-12p40 mRNA by mesangial cells cultured for 20 h was evaluated by RT-PCR.Results:Under basal conditions (no LPS) the production of IL-12 was hardly detected.The levels of IL-12 stimulated by LPS was significantly increased in certain doses,but the levels of IL-12 reduced accompanied with the doses and time increasing of LPS stimulantion.IL-13(1-100 ng/ml) inhibited the protein and mRNA expression of IL-12 in a dose-dependent manner(P

Aim To observe the effects of theaflavin on intracellular calcium concentration(i) level in rat ventricular myocytes and discuss the possible mechanisms.Methods The effects of theaflavin oni were investigated in rat ventricular myocytes.i was detected by laser confocal microscopy and represented by relative fluorescent intensity(FI-FI0)/FI0,%;FI0:control;FI:administration of drugs).Results ① Theaflavin(10,20,40 ?mol?L-1) had no effect on the i of ventricular myocytes in normal Tyrode′s solution.However,it reduced the i of ventricular myocytes in simulated ischemia solution in a concentration-dependent manner.② Pretreatment with Bay k8644(0.5 ?mol?L-1) mostly abolished the effects of theaflavin(20 ?mol?L-1) in simulated ischemia solution.③ Theaflavin(20 ?mol?L-1) markedly inhibited the low concentration of ryanodine-induced i increase in Ca2+-free Tyrode′s solution.④ When the propagating waves of elevated i(Ca2+ waves) were produced by increasing extracellular Ca2+ concentration from 1 mmol?L-1to 10 mmol?L-1,theaflavin(20 ?mol?L-1) could block the propagating waves of elevated i(Ca2+ waves),reduce the frequency and duration of propagating waves,and reduce i as well.Conclusion Theaflavin may reduce the i in isolated rat ventricular myocytes via inhibiting Ca2+ influx by voltage-dependent Ca2+ channel and alleviating Ca2+ release from sarcoplasmic reticulum(SR).

BACKGROUND: Choriocarcinoma is a kind of trophoblastic neoplasm with highly aggressive phenotypes. Forkhead box D3 (FoxD3) is an embryonic and trophoblastic stem cel transcription factor. It plays important roles in different physical and pathological situations such as embryogenesis, carcinogenesis and tumor progression.
OBJECTIVE:To investigate the role of FoxD3 in choriocarcinoma malignancy and the possible mechanism.
METHODS:The human choriocarcinoma JAR cel line was employed in this study. The mRNA and protein expressions of genes were measured by quantitative RT-PCR (qRT-PCR) and western blot, respectively. The FoxD3 specific short hair RNA was applied to down-regulate gene expression. The cel proliferation was evaluatedin vitro by cel counting assay andin vivo by tumor growth. The migration/invasion was determined by transwel assay. The profile of FoxD3 targeted genes was investigated with an Agilent microarray and verified by qRT-PCR.
RESULTS AND CONCLUSION: The FoxD3 mRNA and protein expressions in JAR cells were significantly higher than those in primarily cultured normal trophoblastic cells. Knockdown of FoxD3 by short hair RNA in JAR cells could inhibit cell proliferation and migration/invasionin vitro, and suppress thetumor growth with decreased β-human chorionic gonadotropin secretionin vivo. A profile of seven focal adhesion molecules (ITGA5, ITGB6, THBS4, COL6A3, VTN, NRXN3 and NLGN1) was verified to be targeted by FoxD3. Furthermore, knockdown of FoxD3 by short hair RNA could decrease the activation of focal adhesion kinase. All these findings suggest the overexpression of FoxD3 can contribute to the aggressive phenotype of choriocarcinoma JAR cells by regulating the profile of focal adhesion molecules and focal adhesion kinase.
