Objective To compare the clinical effect of hypertensive intracerebral hemorrhage treated by small bone window craniotomy or craniotomy.Methods 192 cases of patients with hypertensive cerebral hemorrhage treated were selected and divided into minimally invasive group and flap group randomly.Small bone window craniotomy was used in minimally invasive group,while large trauma craniotomy was used in flap group.Complications,rebleeding and short and long term efficacy were recorded and compared.Results 6 cases(6.3％) of.incidence of complications in minimally invasive group,while 14 cases(14.56％) in flap group,the rate in the former group was lower than that in the latter group (x2 =51.308,P ＜ 0.05).There was no significant difference of rebleeding between the two groups (P ＞ 0.05).3 weeks later,GCS score was (10.9 ± 1.8),GOS score (3.3 ± 0.6),BI index (47.8 ±11.5) and 64 cases' nerve function improved (66.7 ％) in minimally invasive group,while GCS score (10.1 ± 2.5),GOS score(2.7 ±0.8),BI index (33.5 ± 15.4) and 31 cases' nerve function improved(32.3％) in flap group.The GOS score,BI index and the situation of nerve function improvement were better in minimally invasive group than that in flap group(t =15.758,56.529,x2 =72.149,P ＜0.05).None of the patients were dead,and there were no significant differences of GCS score between the two groups(P ＞0.05).6 months later,no significant difference of GCS score and mortality were found between the two groups (P ＞ 0.05).but the mean score of GOS and BI index were higher than those in flap group (t =11.647,32.990,P ＜ 0.05).Conclusions Both large trauma craniotomy and small bone window craniotomy could reach therapeutic purposes.However,intraoperative and postoperative complications could be deceased by small bone window craniotomy,and short and long term GOS score and BI are higher,the short term nerve function improvement is better.

A Strategy was established for construction of repertoire antibody library with affinity chromatography purifying antigen, antigen immunizing human lymphocytes, RT-PCR and phage display technology. The colorectal carcinoma-associated antigen CA-Hb3 was purified with affinity column and analysed with SDS-PAGE and Western-blot, then applied for immunizing peripheral blood lymphocytes (PBL) in vitro. The PBL were isolated from ten patients with colorectal carcinoma and cultured with interleukin 2 and pokeweed mitogen, lymphoblast-like cells occurred and colonies formed after immunization. Three VH-CHl(?) and five VL-CL(?,?) genes were amplified from their total RNA and mRNA with RT-PCR. Three VH (?) and 8 VL (?,?) genes were reamplified and randomly combined to construct 24 single-chain variable fragments (ScFv) genes through (Gly_(4)Ser)_(3) linker. ScFv genes digested with Sfi I were cloned into fUSE 5 vector and transformed into MC1061 with electroporation. Repertoire antibody library was obtained with 10~(6) tetracycline-resistant colonies, in which the percentage of ScFv inserts was 85 % . This strategy might be used for humanizing mouse-original monoclonal antibody.

Diagnosis and management of hip injuries has advanced significantly in the past few years with the improvement of arthroscopic techniques of the hip. Many of pathologic conditions previously unrecognized and untreated have been diagnosed and treated correctly under hip arthroscopy . Current application for hip arthroscopy include management of labral tears,osteoplasty for femoroacetabular impingement, thermal capsulorrhaphy and capsular plication for subtle rotational instability and capsular laxity, lateral impact injury and chondral lesions, osteochondritis dissecans, ligamentum teres injuries, internal and external snapping hip, removal of loose bodies, synovial biopsy, subtotal synovectomy, synovial chondromatosis, infection, and certain cases of mild to moderate osteoarthritis with associated mechanical symptoms. In addition,patients with long-standing, unresolved hip joint pain may benefit from arthroscopy. Patients with reproducible symptoms and physical findings that reveal limited functioning, and who have failed an adequate trial of conservative treatment will have the greatest likelihood of success after arthroscopic intervention. Prescise attention to thorough physical examination, detailed imaging,and adherence to safe and reproducible surgical techniques are essential for the success of this procedure.

Objective A new type of bone graft material was constructed by combining calcium phosphate cement(CPC) with bone morphogenetic protein(BMP). In order to evaluate the feasibility to use this material to repair the segmental bone defect in clinic, the ability of CPC was compared with CPC/BMP in bone defects reconstruction by animal experiments. Methods The model of 15 mm bone defect was established in the middle shaft of the radius in 60 rabbits, of which 30 defects were implanted with CPC/BMP composites, 22 implanted with CPC, and the other 8 rabbits served as control group. The specimens were harvested separately at the end of 2, 4, 8, 16 and 24 weeks after operation. In order to observe the formation of new bone and the degradation process of the material, a series of examinations were carried out including of radiography, histomorphology, serum detection, energy dispersion analysis X-ray(EDAX), scanning electron microscope(SEM),bone density detection, mechanical measurement and inorganic substance detection. The results of CPC group and CPC/BMP group were compared on the same condition. Results All the animals survived after operation, and no reactions of toxicity were found. New bone formation was observed to be increasing significantly in CPC/BMP group with the time of implantation. Only little new bone formed in CPC group and no healing was found in the control group. By the end of 24 weeks, new bone had bridged the gap between the proximal and distal fragments in CPC/BMP group. In histomorphological detection, chondrocytes were found at the 2nd week, and woven bone at 4th week in CPC/BMP group. Remodeling of new lamellar bone and absorption of the composite material were observed at the 16th week, and the mechanical strength of the composite material reached almost to normal level at the 24th week. Calcification was significantly higher in CPC/BMP group than that in CPC group examined by EDAX, new bone density detection and measurement of inorganic substance in specimens. During the repairing process of bone defect, the material degraded while new bone formed, the speed of degradation of CPC/BMP was evidently higher than that of CPC group. Moreover, in the process of CPC degradation, the concentration of calcium in serum increased, and the concentration of phosphate in serum kept unchanged. Conclusion The CPC/BMP composite has great potential in bone defects repairing and could be used as a material for bone graft substitute in clinical patients.

ObjectiveTo explore the efficacy of large trauma craniotomy with bilateral frontal coronal incision in treating contusion and laceration of bilateral frontal lobes.MethodsThe clinical data of 68 patients with contusion and laceration of bilateral frontal lobes who were treated with bilateral decompressive craniectomy were analyzed retrospectively.There were 36 cases(observation group) treated with large trauma craniotomy with bilateral frontal coronal incision and 32 cases (control group) given bilateral decompressive craniectomy by stages.The prognosis of two groups were observed and compared.The prognosis was evaluated at 6 months after surgery by Glasgow outcome scale (GOS) score.ResultsThere were 23 cases (63.89％,23/36) who got good recovery,8 cases(22.22％,8/36) with poor prognosis and 5 dead cases (13.89％,5/36) in observation group.There were 11 cases (34.38％,11/32) who got good recovery,9 cases (28.12％,9/32) with poor prognosis and 12 dead cases (37.50％,12/32) in control group.The rate of good recovery and mortality between two groups had significant differences (P ＜ 0.05).ConclusionsThe large trauma craniotomy with bilateral frontal coronal incision can significantly relieve or ease intracranial hypertension of patients with contusion and laceration of bilateral frontal lobes.And it can improve the prognosis and decrease the mortality.

Early detection of HCC is critical for a good prognosis. Therefore, the development of tumor markers that can detect HCC at even earlier stages is urgent. Recent researches show that the human cervical cancer oncogene, gamma-glutamyl transferase mRNA, human telomerase reverse transcriptase mRNA, the proteins such as glypican-3, golgi protein 73, vascular endothelial growth factor and transforming growth factor-β1 could serve as markers for early detection of HCC.

Colon carcinoma is one of the most common malignant neoplasms.The incidence of this disease has been increasing significantly in recent years in China.Ahhough diagnostic and therapeutic methods have been im proved greatly.carcinoma invasion and metastasis are considered to be the main causes of poor prognosis and death. Tumor metastasis is a complicated process with multiple steps and factors.Cell adhesion molecule(CAM)play a very impntant role in this process while it expresses exceptionally or loses its function.CAM is a kind of glycopro tein molecule by the cell synthesis which mediates the intereontact and intercombination between cell and cell or be tween cell and matrix.It takes part in a series of important physiologic and pathologic processes,such as cell signal conduction and activation,cell extension and migration,tumor metastasis and wound healing,and so on.

Epstein-Barr virus infects widely, and has a powerful ability to transfrom into a number of malignant diseases. The infection is mostly latent, without any obvious clinical symptoms. At present, more and more researches have found that cell-mediated immunity,especially T lymphocyte response plays an important role in the control of Epstein-Barr virus infection.
