Objective To investigate the clinical pathology characteristics of the p27 and C-myc protein expression in lung squamous cell carcinoma and adenecarcinoma as well as the correlation between the expressions of them. Method The expressions of p27 and C-mye protein in tumor tissue of 35 cases excised during pulmonectomy for lung squamous cell carcinoma and adenocarcinoma patients were examined using immunochemical method,and compared with 10 cases of normal lung tissue. Results The total positive rate of p27 protein was 17.1%(6/35 ) in 35 eases of tumor tissue, but 90.0%(9/10) in normal lung tissue, and there was significant difference (P< 0.05 ). Between high-moderate and low differentiated tissue,the positive rate had significant difference (P = 0.005). There was no significant difference of p27 protein expression in patients with different tumor size and histology types, as well as with or without lymph nodes metastasis (P > 0.05 ). The total positive rate of C-myc protein was 85.7% (30/35) in tumor tissue, but no expression existed in normal lung tissue (P < 0.05). There was significant difference of C-myc expressions between the tissue with and without lymph nodes metastasis (P =0.013),but there was no significant difference in various tumor size, differentiated degree, as well as histology type(P> 0.05). The expression of p27 and C-myc in lung squamous cell carcinoma and adenecareinoma showed negative correlation.Conclusions The expression of p27 protein is positive in normal lung tissue, but shows outstanding decrease in lung squamous cell carcinoma and adenocarcinoma tissue. Its expression correlates with the differentiated degree. The expression of C-myc is negative in normal lung tissue but shows significant increase in lung squamous cell carcinoma and adenocareinoma tissue and its expression correlates with lymph nodes metastasis. C-myc may be a valuable marker in evaluating prognosis.

Eight-six heroin addicts were randomly divided into the treatment group by electroacupuncture plus Methadone and the control group by single Methadone for comparison of the therapeutic effects. Statistically there was no significant difference in the therapeutic effect (score reduction rate) between the treatment group and the control group (P＞ 0.05). In the treatment group, the dose of Methadone was half of routine dose, but the therapeutic effect was similar and side effect was less, in comparison with full dose in the control group.

ObjectiveTo observe the effect of Nimodipine on the hemorrheology and brainstem auditory evoked potentials (BAEP) in the patients with vertebrobasilar insufficiency (VBI) and to explore the mechanism.Methods50 cases with VBI were divided into Nimodipine group (25 cases) and routine therapy group (25 cases). The hemorrheology and BAEP were measured before the treatment and 1 month later.ResultsThe blood viscosity,including the whole blood viscosity shear value, plasma viscosity and blood fat of patients with VBI was increased. The total abnormity rate of BAEP was 76%. The main abnormity was brainstem type. The hemorrheology and the function of nerve conduction were improved distinctly (P<0.05) after treatment. Compared with the routine therapy group, the level of plasma viscosity was decreased markedly (P<0.05) in Nimodipine group, and peak latency of V wave, interpeak latency of III-V and I-V were also improved significantly (P<0.05).Conclusions Nimodipine can improve the hemorrheology and the function of nerve conduction in patients with VBI.

ObjectiveTo observe the therapeutic effect of standing bed on orthostatic hypotension with cervical spinal cord injury. Methods36 patients with cervical spinal cord injury were divided randomly into the standing bed group and routine treatment group. The blood pressure of all patients were measured every day during rehabilitation treatment. The function of spinal cord was assessed before and after treatment.ResultsThe function of sensory and motor in the two groups were all improved, but there was no statistical difference between the two groups in the grades of spinal cord function. There were 27 patients who had orthostatic hypotension in the study. All the patients with complete spinal cord injury suffered the orthostatic hypotension. There was no improvement in blood pressure of complete spinal cord injury after treatment. In incomplete spinal cord injury patients, there was a significant improvement and the difference of blood presure between lying and standing was decreased in standing bed group after treatment (P<0.05). Compared with routine treatment group, the blood pressure in standing bed group was improved (P<0.05). Conclusions Cervical spinal cord injury could have orthostatic hypotension. Complete spinal cord injury would suffer orthostatic hypotension in different degree. The standing bed treatment could improve the orthostatic hypotension in incomplete spinal cord injury.

Objective To investigate the clinical characters and therapy of primitive neuroectodermal tumor(PNET).Methods A retrospective analysis was conducted.A 36-year-old female patient was showed pain and numbness of the right upper limb and back for 6 months.The cervical spine MRI showed a spindleshaped intradural mass right ventrolateral of spinal cord at C5-7 with in homogeneously enhancing.Surgery and pathologic examination confirmed that was PNET.Combiled with a series of literatures to analyse the clinical characters Results Surgery was performed to remove the tumor and decompression combined with radiotherapy.The pathologic examination and immunohistochemical analysis revealed that it was PNET.MRI identified local recurrence in spinal canal at 3 month later after surgery.Conclusion Spinal PNET is an uncommon intraspinal tumor with poor prognosis.Histopathology is the evidence of diagnosis.Optimal therapy has not yet been found.Surgical resection with the combination of chemo-radiotherapy or radiotherapy might get the better outcomes.Multidisciplinary treatment should be further clinical required.

Objective To explore the efficacy of endovascular treatment for closed articular artery injuries.Methods The clinical data of 13 patients from Jan 2010 to Dec 2014 treated for closed articular artery injuries were analyzed retrospectively.The location,severity and extent of arterial injury were confirmed by intraoperative arteriography.The diameter and length of the injured arteries were measured.The guidewire was sent to the lesion site and working wire pathway was established.When the guidewire was difficult to pass through the lesion site,femoral and posterior tibial or radial artery may be used to establish working wire pathway.The stent or stent-graft was implanted through the contralateral femoral artery or distal end of ipsilateral artery.Results Intraoperative angiography confirmed intimal injury (n =2),partial transection (n =5),complete transection (n =5) and arteriovenous fistula (n =1).Eighteen stents or stent-grafts were implanted.Treatment was successful in all patients without peiropeartive death and procedure-related complications.All were followed up for 15 to 48 months and the mean follow-up was (30 ± 11) months.Three patients with stent lumen stenosis less than 50％ as showed by angiography.There was no stent fracture,displacement,or deformation.Conclusions Endovascular treatment for closed articular artery injuries is of less invasion,shorter operative time and quick postoperative recovery.

Objective To investigate the alteration of the default-mode network (DMN) in the patients with minimal hepatic encephalopathy (MHE) using resting functional MRI, and to explore its underlying clinical significance. Methods Fourteen MHE patients and 14 age-matched normal controls underwent standard resting state functional MRI scan. The components representing DMN were picked out after separation of independent component analysis. One and two sample t-tests were used to observe the changes of DMN in the patients in contrast to the controls. Results Typically spatial distributions of the DMN were found in both MHE patients and controls. Comparison results revealed that there was significantly reduced functional connectivity in the left posterior cingulate cortex, bilateral anterior cingulate cortex, bilateral medial prefrontal cortex, left parahippocampal cortex in MHE patients, while functional connectivity increased in the right precuneus. Conclusion Resting state functional MRI can be used to observe DMN changes in MHE patients. In MHE patients, there is reduced DMN activation in the widespread regions, while the activation of right precuneus increases.

Objective To optimize the therapeutic dose and time window of picroside Ⅱ in treating cerebral ischemic injury in rats by orthogonal test. Methods The forebrain ischemia models were established by bilateral common carotid artery occlusion (BCCAO) method. The successful models were randomly grouped according to orthogonal experimental design and treated by injecting picroside Ⅱintraperitoneally at different ischemic time with different doses. The concentrations of MDA, NO and H2O2 in serum and brain tissue were respectively determined by thiobarbituric acid assay, nitratase reductase assay and chemiluminescence immunoassay. Results The optimized composition of the therapeutic dose and time window of picroside Ⅱ in cerebral ischemic injury were ischemia 1.5 h with 10 mg/kg, 1.5 h with 20 mg/kg and 1.5 h with 10 mg/kg body weight according to the expressions of MDA, NO and H2O2 in serum, and ischemia 1.5 h with 10 mg/kg, 1.5 h with 20 mg/kg and 1.5 h with 20 mg/kg body weight according to the expressions of MDA, NO and H2O2 in brain tissue. Conclusion On the basis of the principle of lowest therapeutic dose with longest time window, the optimized composition of the therapeutic dose and time window in cerebral ischemic injury is injecting picroside Ⅱ intraperitoneally with 10-20 mg/kg body weight at ischemia 1.5 h.
