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.

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.

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.

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.

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.

Carcinoma of the esophagus is the second most common cause of cancer-related-death in women,and fourth in men in China.The prevalence rate of adenocarcinoma of esophagus has increased in the western countries recently too.Unfortunately,the treatment result of esophageal cancer is very poor,and only 15%～20% of all esophageal cancer patients will be alive 5 years after diagnosis.With the development of radiologic techniques and molecular biology,the esophageal cancer patients are given on individualized treatment modality.This paper reviewed several interesting topics,including operation for esophageal cancer,new technologies for pre-operative staging,multidisciplinary treatment as well some data from the Shanghai Cancer Hospital.

Objective:To analyse pros and cons of Shikani laryngoscope anatomically during nasal intubation.Methods:60 pa-tients,with ASAⅠ -Ⅱ,aged 1 9 to 29 years old,undergoing titanium plate and titanium screw removal surgery after orthognathia, were randomly divided into Shikani group (S group,n =30)and HC video laryngoscope group (V group,n =30).Successful intuba-tion rate of the first attempt,total time cost,nasal bleeding rate and the incidence of postoperative airway complications were compared. Results:Compared with group V,the time cost of group S was significantly lower(P <0.05).But the rate of successful intubation for the first attempt,nasal bleeding rate and incidence of complications were the same in both groups(P >0.05).Conclusion:Shikani la-ryngoscope is faster,less invasive with easy maintenance in nasal intubation.
