Conclusions MRI cranial surface locating device can precisely delineate the surgical target area. The device is easy to operate and also can help to design the rational surgical approach with minimum injuries , significantly improve accuracy of locating small intracranial space-occupying lesions and it is safe , effective and worthy of widely used clinically.

Objective To discuss the technique of supraorbital transeyebrow keyhole approach microsurgery for sellar tumors. Methods A total of 33 cases of sellar tumors were treated in this hospital from July 2001 to June 2004. The resection of the tumor was achieved by way of a supraorbital eyebrow minicraniotomy through a 2.0 cm ? 3.0 cm keyhole approach. The surrounding cisterns of the sellar area were opened to expose underlying structures under microscope at proper angles. Results Of 26 cases of hypophysoma, a total resection was performed 19 cases, and a subtotal resection in 7 cases. Of 4 cases of craniopharyngioma, a total resection was performed 3 cases, and a subtotal resection, 1 case. One case of meningioma received a total resection, and 1 case of optic chiasm glioma underwent a partial resection. Postoperatively, transitory diabetes insipidus was observed in 5 cases, and grand mal epilepsy occurred in 1 case. There were no infection or bleeding after the operation. All the 33 cases were followed for 4~36 months (mean, 27 months). No recurrence of tumors was seen in the 24 cases of total resection. Postoperative radiotherapy was given in 7 cases of subtotal resection of hypophysoma, 1 case of craniopharyngioma, and 1 case of optic chiasm glioma, and no apparent enlargement of tumors was found. Conclusions Supraorbital transeyebrow keyhole approach microsurgery minimizes the unnecessary exposure of the brain and postoperative complications.

Chitosan, a linear polysaccharide, is obtained by chitin N deacetylation. Its ?(1 4) glucosidic bond is not stable and breaks easily in acid condition. In this study, chitosan of different molecular weights(MW) was prepared by acetic acid degradation. Chitosan was dissolved at 3%(w/v) concentration in 1%(v/v) acetic acid and the solution was dried at 50 degree C. We get chitosan membranes of different MW after neutralization with aqueous NaOH. The membranes are transparent, elastic and have good intensity. The permeability studies on chitosan membranes were going on with a permeable install made by our laboratory. It was determined by the transmission concentration of NaCl, L Tyr, glucose and calf albumin. We compared the permeability property with different MW chitosan membranes. The result implied that all of the four samples could permeate through the chitosan membranes. And the permeability property of the membrane increased with the chitosan MW decreaseing.

Objective To analyze the impact of uterine septum on pregnancy and influencing factors on postopera-tive pregnancy. Methods 125 patients with septate uterus and bearing requirement who underwent TCRS were fol-lowed up to assess fertility outcome. The clinical data was retrospectively analyzed. Results Spontaneous abortion rate was 70.40%and 19.39%, live birth rates was 10.40%and 72.45 %in preoperation and postoperation respec-tively. The difference was statistically significant ( < 0.05). Spontaneous abortion rate in older than 35 years old group was significantly higher than that in younger than 35 years old group, but live birth rate was lower. There was no significant difference in different times of operation in uterine cavity, number of abortion and septum length and so on. Conclusions TCRS can significantly improve pregnancy outcome. The age has influence on postoperative pregnancy outcome. Abortion numbers, septum length, septal base width, intrauterine device (IUD) and hormone re-placement therapy (HRT) may have no effects.

Objective To investigate whether the apoptosis-2 ligand (Apo-2L),known as tumor necrosis factor-related apoptosis-inducing ligand (TRAIL),could enhance irradiation-induced apoptosis in lung adenocarcinima H1975 cells that are resistant to the epithelial growth factor receptor (EGFR)-TKI.Methods Adenocarcinima H1975 cells were randomly divided into four groups:the control group,Apo2L group,irradiation group,and both Apo-2L and irradiation group.H1975 cells were pretreated with Apo2L under different concentrations of 200 and 228 ng/ml at 24 h before irradiation with doses of 1,1.5,2,2.5,3,3.5 and 4 Gy.The apoptosis rates of all groups were analyzed by flow cytometry 24 h post-irradiation.The inhibition rates of cell proliferation were measured by the MTT assay.Results MTT assay showed that the Apo-2L treatment significantly inhibited cell proliferation(x2 =136.17,P ＜ 0.05).The apoptosis rates of the four groups were different significantly,and the apoptosis rate of radiation combined with drug group was significantly higher than the other three groups(x2 =78.02,P ＜0.05).Conclusions The Apo-2L could not only inhibit the proliferation but also promote radiation-induced apoptosis of adenocarcinoma H1975 cells.

Objective To investigate the clinical application and surgical techniques of lateral-orbital keyhole approach to clip ruptured tiny aneurysms.Methods A retrospective analysis was performed on the clinical data of 56 patients with ruptured tiny aneurysms, including examination methods, imaging features, diagnosis and treatment process, and operation effect, which underwent lateral-orbital keyhole approach from January 2013 to April 2014.Results Among 56 patients with a total of 61 aneurysms(56 tiny aneurysms) was examined by CT angiography (CTA) and/or digital stubtraction angiography (DSA), all achieved successful clipping with a rupture rate of 16％(13 cases).Forty-two cases got a good recovery,8 cases owned the self-care ability, and 6 cases could carry out daily lives with help.There was no rebleeding and mortality, according to a 2-28 months' follow-up of 49 patients.Conclusion As a surgical approach for Willi'S cycle aneurysm,the lateralorbital approach is simple,rapid,minimally-invasive way.It is available in the clipping of ruptured tiny anterior communicating aneurysms.The option of operative time, perfect microdissection and exquisite intraoperative microinvasive operative skills, will be the key point of clipping aneurysms, preventing and controlling of intraoperative bleeding.

Objective To explore the use of enzyme-linked immunosorbent assay(ELISA) to test the serological BP180NC16A-ELISA index in patients with bullous pemphigoid (BP) and investigate the relationship of this index with disease monitoring and therapeutic guidance.Methods The serological BP180NC16a-ELISA index at different times was examined in twenty BP patients with ELISA kit and monitor changes of pre-treatment BP180NC16a-ELISA index condition score and efficacy relationship..Results Twenty patients tested by ELISA had 19 cases of positive patients with positive rate of 95.0％ and one case negative with negative rate of 5.0％.After treatment,19 cases (19.60 ±4.63)d became stable,and condition score was (3.75 ± 1.37) points.After continued treatment (28.75 ± 6.11) d entering clinical remission,condition score was (2.25 ± 1.21)points.Compared with the score before treatment condition [(5.55 ± 1.61) points],differences were statistically significant (Z =-3.808,-3.965,P ＜ 0.01),and clinical remission score below clinically stable condition (Z =-3.808,P ＜0.01).A total of 19 cases of patients' pre-ELISA treatment index were positive correlation with after treatment stable period and clinical remission period (rs =0.788,0.752,P ＜ 0.01).Conclusions This study demonstrated that ELISA-detected BP180NCI6a-ELISA index was positively correlated with the BP disease severity and clinical course,which could be as the guideline to monitor and clinical treatment.

Objective To study the anatomic morphology of posterior column of ilium(PCI)and valne of lumbo-iliac fixation(LIF)in pelvic ring reconstruction following communited Denis Ⅲ sacral fractures.Methods A total of 17 hemi-sectional pelvis and dry ilia were selected to observe the length,width and height(safety and standard)of PCI,when a detailed description was done on the methods determining entry point and operation techniqus for iliac screws anchoring.Nine patients with eommunited sacral fractures involving Denis Ⅲ areas combined with neurologic deficits were decompressed for recovery of neurological function and reconstruction of pelvic ring by using LIF.Postoperative follow-up was done on role of LIF and result of neural rehabilitation.Results PCI was mean 110.57 mm in length,24.24 mm in width,14.54 mm in standard height and 31.46 mm in safe height.Nine patients could turn over in bed immediately following operation and walk one month later.A follow-up for 13-37 months in eight patients showed stable reconstructed pelvic ring,sound function of movement and bone graft fusion,which met the target of keeping stability of fractured extremity and pelvis.Conclusions pCI can provide anatomic support for LIF.When decompression and fixation is needed for sacral fractures combined with anterior pelvic ring disruptions,LIP can provide stable fixation and play an important role in reconstruction,nursing and rehabilitation of pelvic ring.
