Objective: : T o study the microanatomy of the facial nerve in the cerebellopontine angle (CPA) a nd the internal auditory meatus (IAM) for the preservation of the facial nerve i n the acoustic neurinomas surgery. Methods: Forty sides of CPA f acial nerve of 20 adult cadaver heads were examined. Results: In the pontomedullary sulcus the facial nerve (1.98? 0.10) mm anterior to the vestibulocochlear nerve,(8.76?1.42) mm lateral to the abducent nerve at the points where the nerves join the brain stem at the lateral end of the sulcu s, (8.15?2.18) mm above the junction of the Ⅸ nerve with the medulla. There were 62 nutritious artery supplying the facial nerve in the CPA, mainly from the anterior inferior cerebellaris artery (AICA) and its branches; and 17 in the IA M were mostly from the internal auditory arteria (IAA). Conclusion: To be familiar with the microanatomy of the facial nerve in CPA and IAM is h elpful for localizing the facial nerve and improve its preservation in acoustic neuroma surgery.

Objective To explore the correlation between membrane targeting of rodent Muc3 C-terminal domain and proteolytic cleavage blockage within its SEA module and N-linked oligosaccharides inhibition.Methods COS-1 cells were transfected with three different expression vectors containing rodent Muc3 C-terminal domain,namely p20,p20t and p20s/a by lipofectAMINE reagent.Inhibition of N-glycosylation of the expressed protein was performed by using tunicamycin.The transfected COS-1 cells(fixed or unfixed) were detected by immunolocalization experiments(anti-V5 and anti-Myc antibody) for the protein expression.Results In fixed COS-1 cells,the expressed product of p20 transfectant detected using both anti-Myc and anti-V5 antibodies was found to localize in perinuclear position and on the plasma membrane.While in the unfixed cells,immunostaining was only confined on cell surface using anti-V5 antibody.The expressed product of p20t transfectant was detected by anti-V5 antibody to localize only in perinuclear region,as observed in a few fixed cells.The distribution of p20s/a fluorescence resembled that of p20 transfectant.Plasma membrane targeting of the non-glycosylated products due to tunicamycin treatment still occurred in transfected COS-1 cells and resembled the glycosylated products.Conclusions The blockage of proteolytic cleavage within C-terminal domain of rodent Muc3 and its inhibition of N-linked oligosaccharides in SEA module cannot affect its membrane targeting.The only apparent requirement for membrane targeting is the transmembrane and/or cytoplasmic tail segments which exist in the C-terminal domains of rMuc3.

Objective To investigate the expression of granulocyte macrophage-colony stimulating factor(GM-CSF)in skin lesions and sera of patients with pustular psoriasis and psoriasis vulgaris.Methods Tissue specimens were obtained from the lesions of 15 patients with pustular psoriasis,15 patients with psoriasis vulgaris and 15 normal human controls.Immunohistochemistry and dual antibody sandwich enzyme-linked immunosorbent assay(ELISA)were carried out to detect the levels of GM-CSF in the tissue and serum specimens from the patients and normal human controls,respectively.Results Significantly higher levels of GM-CSF were observed in the tissue and serum specimens from patients with pustular psoriasis and psoriasis vulgaris compared with the normal controls(all P ＜ 0.01),as well as in those from the patients with pustular psoriasis compared with the patients with psoriasis vulgaris(both P ＜ 0.01).Conclusion GM-CSF may be involved in the pathogenesis of psoriasis.

Objective To explore the effect of atorvastatin on postoperative complications after the burr hole drainage of chronic subdural hematoma (CSDH). Methods The clinical data of 172 CSDH patients who had underwent the burr hole drainage were retrospectively analyzed. Among them 82 patients were given atorvastatin (atorvastatin group), and 90 patients were not given atorvastatin (control group). The postoperative complications were compared between 2 groups. Results All patients were followed up for 6 months. The total incidence of postoperative complications in control group was significantly higher than that in atorvastatin group:47.78%(43/90) vs. 31.71%(26/82), and the recurrent rate of subdural hematoma and incidence of subdural effusion in control group were significantly higher than those in atorvastatin group: 22.22% (20/90) vs. 8.54% (7/82) and 28.89% (26/90) vs. 12.20%(10/82). There were statistical differences (P<0.05). There were no statistical difference in the incidences of pneumocephalus, acute epidural/subdural hematoma and brain damage induced by drainage tube (P>0.05). Conclusions Atorvastatin can improve the prognosis of CSDH patients, especially in reducing the incidence of recurrent subdural hematoms and subdural effusion.

Objective To study the efficacy of movement imagination combined with biofeedback for stroke patients with upper extremity dysfunction. MethodsEighty stroke survivors were recruited and randomly divided into a movement imagination group ( n =40) and a movement imagination combined with biofeedback group ( n =40).Their EMG mean values during wrist dorsiflexion were amplified and calculated.Fugl-Meyer upper extremity function scores (FMAs) and the modified Barthl index (MBI) were recorded before and after 6 weeks of treatment.ResultsAfter 6 weeks of treatment the two groups had significantly higher mean EMG values,FMA scores and MBI scores,but the effects in the combination group were significantly better than those in the simple movement imagination group. ConclusionMovement imagination can be made more effective by combining it with biofeedback for promoting the recovery of stroke patients with upper extremity dysfunction.

Objective The C-terminal domain of rodent Muc3 is proteolytically cleaved.This study is to explore the relationship between N-linked oligosaccharides in SEA module and the proteolytic cleavage within C-terminal domain of rodent Muc3.Methods Truncated rodent Muc3 C-terminal domains with complete SEA module(p20SEA) were produced by site-directed mutagenesis to insert a stop code in the required place.Proteins were detected by pulse/chase and immunoprecipitation method,or SDS/PAGE and Western blot.Inhibition of glycosylation of the expressed protein was performed by using tunicamycin.Results Muc3 C-terminal domain was posttranslationally cleaved to produce a V5-tagged 30 000 extracellular glycopeptide and a Myc-tagged 49 000 membrane-associated glycopeptide.Treatment with tunicamycin to transfected COS-1 cells led to the abundant production of 60 000 uncleaved and whole-length Muc3 C-terminal domain,the 30 000 N-terminal fragment shifted to 22 000 and 49 000 C-terminal fragment shifted to 41 000 after deglycosylation.The truncated Muc3 C-terminal domain containing complete SEA module but without the following residues led to production of 36 000 uncleaved and whole-length protein,and 30 000 cleaved product shifted to 22 000 after deglycosylation.Conclusion Proteolytic cleavage in both complete rodent C-terminal domain and complete SEA module without the following residues were partially inhibited by tunicamycin.

ObjectiveTo discuss the diagnosis and treatment of rupture of spleen in a base-level hospital with limited conditions. MethodsThe clinical data, diagnosis of bleeding by ultrasound, and results of (nonoperative) and operative treatment of 317 patients with rupture of spleen in Vila Central Hospital of the (Republic) of Vanuatu were retrospectively analyzed. ResultsUltrasound diagnosed 30 patients with (subcapsular) hemorrhage and 287 patients with true rupture of spleen. Based on ultrasound results, (conservative) treatment was used for 29 patients and 288 patients underwent operation. Conclusions(Ultrasonography) had a high positive diagnostic rate for rupture of spleen, and the diagnosis of bleeding volume was consistent with the findings at operation. The findings on ultrasonography can be considered in selection of cases with appropriate indications for splenectomy. Ultrasonography is an effective method for use in the (treatment) of rupture of spleen.

Objective To study the time-course relationship of eotaxin mRNA and TNF-? mRNA expression in the lung tissue of sensitized mice after antigen challenge and the effects of Cryptoporus polysaccharide (CP) on these expression. Methods Eotaxin mRNA and TNF-? mRNA expression was determined by semi-quantitative RT-PCR. The function implications of eotaxin mRNA and TNF-? mRNA expression were examed by detecting the number of total leucocyte and eosinophils in bronchoalveolar lavage fluid (BALF). Results Peak level of TNF-? mRNA expression appeared at 8 h and eotaxin mRNA expression at 24 h in the lung tissue of sensitized mice after antigen challenge. Compared with the control group, total numbers of leukocyte and eosinophil in BALF increased in sensitized mice. CP 3, 10, and 30 mg/kg inhibited eotaxin mRNA and TNF-? mRNA expression, and inflammatory cells accumulation in airway of the sensitized mice in a dose-dependent manner. Conclusion The mechanism of inhibitory effects of CP on eotaxin mRNA and TNF-? mRNA expression may be related to the anti-allergic inflammation.

Objective To explore the evolution and treatment of traumatic subdural effusion(TSE).Methods The clinicsl materials of 66 patients with TSE were analyzed retrospectively.Results 53 patients were cured with comervative therapy,and other patients were evolved into chronic subdural hematoma(CSDH).8 patients with CSDH were cured with surgery and others with conservative therapy.Conclusion Patients with TSE don't need surgery,and then patients with clinical characteristics will be operated when TSE evolves into CSDH.

Objective To explore the relationship between left ventricular volume parameters and cardiac function in elderly patients with heart failure. Methods From January 1st, 2012 to December 31st, 2014,five hundred and twenty-eight heart failure elderly patients with coronary heart disease,hypertension,heart valve disease, dilated cardiomyopathy, and hypertrophic cardiomyopathy in Kailuan General Hospital were collected in this study. The left ventricle diastolic end volume ( LVEDV ) , left ventricle end systolic volume ( LVESV) and left ventricular ejection fraction of the patients were measured. The concentrations of N type brain natriuretic peptide ( NT-proBNP ) and related biochemical indexes were detected. Results Among the 528 patients with cardiac insufficiency,367 were males and 161 were females. Among them,there were 199 cases of heart function I,163 cases of heart function II,99 cases of heart function III and 67 cases of heart function IV. Correlation analysis showed that the correlation coefficients of LVEDV, LVESV and age were 0. 431 ( P=0. 001) ,0. 472 ( P=0. 001 ) and 0. 243 ( P<0. 001 ) , respectively. Logistic regression analysis showed that LVEDV ( OR=2. 654, 95%CI 2. 124-3. 894, P=0. 004 ) , LVESV ( OR=2. 939, 95%CI 2. 539-3. 256, P=0. 001),LVESV),NT-proBNP (OR=2. 921,95%CI 2. 888-3. 562,P=0. 002) were risk factors for heart failure. Conclusion The correlation between LVESV and cardiac function in elderly patients with heart failure is better than that in LVEDV,and the correlation between the two and cardiac function is better than that of age.
