In order to investigate the relationship between sex hormone receptor or glucocorticoid receptor(GR) and hepatocellular carcinoma(HCC), the contents of androgen receptor(AR) and estrogen receptor(ER) in peripheral blood lymphocytes, and GR in peripheral blood leukocytes from 13 patients with HCC and 23 healthy persons were measured by the method of radio-ligand receptor binding. The results showed that the contents of ER and AR in control group were 616?06 and 687?09 site/cell respectively: and those in HCC group were 968?20 and 2903?60 site/cell; while the content of GR in control group was 5360?1684 site/cell, and those in HCC with and without cirrhosis group were 3112?130 and 4536?201 site/cell respectively. The level of AR indicated that HCC is well correlated with AR and HCC may be an androgen-dependent tumor. The GR level is negatively correlated with the degree of liver cirrhosis. The result demonstrated that the GR contents reflect the degree of liver cirrhosis.

As a transmembrane protein, β-amyloid precursor protein(β-APP) distributes extensively in the central nervous system, has the effect of neurotrophic, and neuroprotective, promote neurite growth and synaptogenesis, β-amyloid(Aβ) is the digestion products of its precursor-APP in the pathological conditions, and it is the main component of senile plaques-the main pathological changes of Alzheimer' s disease (AD), its toxic effects can also induce neuronal apoptosis, The expression of the two proteins after brain injuried has a close relationship with the injury, cognitive dysfunction, Alzheimer' s disease and the pathophysiological changes of central nervous system. To explore its expression in the brain after traumatic brain injury can determine the degree of injury, assess the prognosis and open up new avenues for the treatment of traumatic brain injury.

Objective To determine the expression of inducible nitric oxide synthase (iNOS) in brain after cerebral hypoxia / reoxygenation and the effects of preoxygenation with different concentrations of oxygen in rats.Methods Seventy-two male Wistar rats weighing 250-300 g were randomly divided into 4 groups : group Ⅰ, Ⅱ ,Ⅲ ,and Ⅳ . Each group was further divided into 3 subgroups : a, b, c. Group Ⅰ a, Ⅱ a, Ⅲ a and Ⅳa were preoxygenated with 21 % O2 (Ⅰa), 50 % O2 (Ⅱ a) , 75 % O2 (Ⅲa) and 95 % O2 (Ⅳ a) for 30 min. GroupⅠ b-Ⅳb were subjected to hypoxia (5 % O2 ) for 20 min after preoxygenation. Group Ⅰc-Ⅳc were reoxygenation (98 % O2) for 20 min after preoxygenation and hypoxia. The animals were sacrificed 48 h after the experiment. Brains were immediately removed for microscopic examination and determination of iNOS expression in brain using immuno-histochemistry technique. Results The number of iNOS positive cells was significantly greater in hypoxia groups than that in preoxygenation groups ( P

It is difficult to reflect the properties of samples from the signal directly collected by the low field nuclear magnetic resonance (NMR) analyzer. People must obtain the relationship between the relaxation time and the original signal amplitude of every relaxation component by inversion algorithm. Consequently, the technology of T2 spectrum inversion is crucial to the application of NMR data. This study optimized the regularization factor selection method and presented the regularization algorithm for inversion of low field NMR relaxation distribution, which is based on the regularization theory of ill-posed inverse problem. The results of numerical simulation experiments by Matlab7.0 showed that this method could effectively analyze and process the NMR relaxation data.

Objective To investigate the clinical outcome of modified large decompressive craniectomy in treatment of severe traumatic brain injury combined with acute subdural hematoma. Methods A retrospective analysis was carried out to compare the clinical outcome of large decompressive craniectomy (treatment group) for 81 patients with severe traumatic brain injury combined with acute subdural hematoma from July 2007 to June 2010 and that of standard large trauma decompressive craniectomy (control group) for 65 patients with same injuries from July 2004 to June 2007. Results According to the Glasgow outcome scale at the end of month 6 after injury, there were 21 patients (GCS 5 points) with good recovery, 19 (GCS4 points) with moderate deficit, 24 (GCS 3 points) with severe deficit, five (GCS 2 points) under persistent vegetative status and 12 (GCS 1 points) deaths in the treatment group,with good prognosis rate (good recovery and moderate deficit) of 49% (P ＜ 0.05) and poor prognosis rate of 51%. However, only 21 patients got favorable outcome, including 12 patients (GCS 5 points)with good recovery and nine (GCS 4 points) with moderate deficit; 44 patients got unfavorable outcome (68%), including 22 patients (GCS 3 points) with severe deficit, three (GCS 2 points) under persistent vegetative status and 19 (GCS 1 points) deaths in the control group (P ＜0.05). Furthermore, the incidences of delayed intracranial hematomas and subdural collection of fluid in the treatment group were significantly lower than those in the control group (P ＜ 0.05). Conclusion Modified large decompressive craniectomy can significantly improve the outcome and reduce complications of patients with severe traumatic brain injury combined with acute subdural hematoma.

Objective To explore the role of improved cranioplasty plus ventriculoperitoneal shunt in early treatment of hydrocephalus secondary to decompressive craniectomy for patients with severe craniocerebral injury. Methods A retrospective study was performed on 45 patients complicated by hydrocephalus after decompressive craniectomy for severe craniocerebral injury treated with early stage improved cranioplasty plus ventriculoperitoneal shunt from January 2006 to December 2010.Then,the clinical data,complications and outcomes were summarized. Results All operations were carried out 38-80 days after injury.The postoperative complications were distal obstruction of ventriculoperitoneal shunt in two patients and intracranial infection in one.The clinical symptoms were obviously improved in 36 patients (80％) and the cerebral ventricle was diminished in 34 (76％) one month postoperatively.The Glasgow Outcome Scale (GOS) at discharge was good in eight patients,moderate disability in 19,severe disability in 13 and prolonged coma in five,where better recovery (good recovery and moderate disability) in 27 patients (60％) showed significant improvement compared with preoperation ( x2 =23.47,P ＜0.01 ). Conclusion Early cranioplasty plus ventriculoperitoneal shunt is an effective and safe method for treatment of the complicated hydrocephalus after decompressive craniectomy for severe craniocerebral injury.
