This is a preliminary report using APPLE I type microcomputer to diagnose the nature of intra-cranial tumor (ICT). A computer program was made. All clinical data of 520 cases of intracranial tumors proved by operation and pathology were put into the computer for analysis. The cases were di vided into two groups: the 1st 120 cases were used to make a stepwise regression analysis to get a multiple linear regression equation; and the 2nd 400 cases were tested to prove the reliability of the e quation and diagnose the nature of ICT. The reliability was 85.6%.From the preliminary study, the formula that was derived for clinical purpose to evaluate the nature of ICT depends upon 7 dependent variables. It may be a supplement to evaluate the nature of ICT in early stage.

Severe head injury is the main cause of disability and death. And it is one of the most concerned topics in military medical research. A great deal of achievements involving basic and clinical researches on the severe head injury have been made in recent years. Many animal models of head injury have been established.The mechanisms of brain edema, secondary brain and diffuse axonal injury have been preliminary elucidated,broadening the understanding in the mechanism of repair and clinical treatment. We analyed and summarized these achievements retrospectively in this article, the aim of which is to improve the clinical treatment result for severe head injury.

Based on the objective law that the nickel ion beam can wantonly changed. NGCAAS-Ⅱis a new designed circuit used for clinical element microdetecuon on Atomic Absorption Spectrophotometer (AAS).It effectirely lessons the thermowidening,self- absorption of spectral line and interference of ion line,thus comprehensively improves the practical value of AAS.Its energy is 100 times bigger than the energy of square circuit. Besides,if abtains better signal-to-noise ratio and anti-interference ability.Farther more, it has better sensibility and background-correction.

It is one of the difficulties to treat basicranial tumor by neurosurgery. A brief account of its definition, classification and diagnostic measures is given, and its surgical curative effect is evaluated.

Diseases in the vertebral canal are very common and detrimental to health. The author briefly summarizes their diagnosis and contemporary microsurgical treatment, and points out that great attention should be paid to their early diagnosis and microsurgical treatment, because they are the key measures for a satisfactory outcome.

Objective To investigate prognostic factors for gastric cancer patients with liver cirrhosis.Methods The clinicopathological data of 52 gastric caner patients with liver cirrhosis operated on between March 1994 and March 2006 were analyzed retrospectively and the prognostic factors were evaluated.Significant factors were then entered into a Cox regression analysis.Results The postoperative 1-3- and 5- year survival rates for these 52 patients followed up were 78％,44％ and 33％.Univariate analysis revealed that age,Borrmann type,histology timue typing,tumor size,pTNM stage,Child-pugh grade,postoperative complications,ascites,and albumin level were statistical significance for survival rate (P ＜ 0.05 ).Multivariate analysis demonstrated that pTNM stage,Child-pugh grade,ascites were independent prognostic factors affecting prognosis( P ＜ 0.05 ).The risk of Child-pugh grade is 3.005,the risk of pTNM is 1.594.Conclusions Compared with pathological disease stage of the gastric cancer,liver function affects more on the prognosis of cirrhotic gastric cancer patients undergoing gastrectomy.In Child-pugh grade B or C cases,postoperative liver dysfunction was the main concern.While those of Child-pugh grade A should undergo standard D2 gastrectomy.

Objective To explore the effects of p38 mitogen-activated protein kinase (MAPK) on apoptosis of small intestinal epithelial cells after transplantation in rats. Methods Small intestinal transplantation was performed in SD and Wistar rats. The recipients were divided into three groups: isograft group (Wistar→Wistar group), allograft group (SD→Wistar group) and allograft+cyclosporine A group (SD→Wistar+CsA group). The grafts were harvested on day 1, 3, 5 and 7 after operation. All graft samples were subjected to histological examination. The apoptosis of graft epithelial cells was detected by TUNEL method. p38 MAPK was measured by Western-blotting method and serum TNF-? was determined by ELISA. Results Mild, moderate and severe rejection reaction occurred in the SD→Wistar group, it was showed that the number of apoptotic cells increased with the severity of the rejection reaction by TUNEL. In SD→Wistar group, the numbers of apoptotic cells were significantly higher than those of the other two groups (P0.05). The expression of p38 MAPK and the level of serum TNF-? were positively correlated with apoptosis in small intestinal rejection after transplantation (r=0.875, P

Objective To analyze the reasons of internal fixation failure for subtrochanteric fractures of the femur and indicate the methods for avoiding the complications. Methods Thirty-nine patients with internal fixation failure for subtrochanteric fractures of the femur were treated from January 1993 to January 2004. There are 34 males and 5 females with an average age of 37 years (range from 21 to 65 years). The causes of injury included falls from bicycle in 3 cases, pedestrain injury in 1 case, traffic accident in 28 cases and falls from heights in 7 cases. The pattern of the fractures included Seinsheimer ⅡA type in 5 cases,ⅡB type in 2 cases,ⅡC type in 1 case,ⅢA type in 18 cases,ⅢB type in 1 case,Ⅳ type in 3 cases,Ⅴ type in 9 cases. The initial operation included open reduction and fixed with cerclage wires in 1 case, open reduction and fixed with Kuntscher nail and cerclage wire in 13 cases, closed reduction and fixed with Russell-Taylor reconstruction nail in 1 case, open reduction and fixed with 135? DHS in 6 cases, open reduction and fixed with plate in 18 cases. Two cases failed in 8 weeks postoperation, 26 cases failed in 6 months postoperation and 11 cases failed over 6 months. The pattern of failure of internal fixation include varus deformity of fracture in 35 cases, cutout of the lag screw from the femoral head in 2 cases and over medial migration of the distal femoral shaft in 2 cases. The reasons of internal fixation failure were nonanatomically reduction of fractures, unrigid interal fixation, over early weight bearing and poor placement of lag screw. Results The internal fixtion of fractures were revised, including open reduction and fixed with kuntscher nail in 2 cases, fixed with interlocking nail in 23 cases, fixed with 135? DHS in 6 cases, fix with plate in 4 cases, total hip replacement in 4 cases. The mean duration of follow up was 23 months (range from 19 to 37 months). The average time of fracture healing was 11.5 months (range from 11 to 13 months). Conclusion There are higher bending loads at the subtrochanteric area of the femur due to the eccentric loading. If extramedullary implant is selected, the stability at the medial cortex of the femur must be reconstructed intraoperatively and bone grafting is required.

0.05), but in Wistar→SD group and Wistar→SD+CsA group, the serum IL-1? (levels) (increased) as the number of apoptotic cells increased(P

Coverage of the left subclavian artery is often necessary to establish an adequate landing zone in patients undergoing thoracic endovascular aortic repair,which can avoids endoleaks that contribute the important aspect of technical success of thoracic endovascular aortic repair.However,there have been controversial whether the routine revascularization of left subclavian artery benefits in preventing the complications in perioperative,like cerebrovascular accident,and which approach of revascularization should be taken for more advantages.In this review,the disputes have been discussed between the routine revascularization and selective revascularization of left subclavian artery based on clinic research published in recent years,and also introduce the progress in open surgery and endovascular technique of left subclavian artery revascularization.
