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.

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.

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.

BACKGROUND:Nowadays treatment of osteoarthritis with drugs is not ideal. In recent years, more and more scientists try to use stem cells to treat osteoarthritis.
OBJECTIVE:To explore the stem celltreatment for osteoarthritis in order to promote its clinical application and find out its difficulties.
METHODS:A computer-based online search of PubMed database and CNKI database between March 1998 and October 2013 was performed to search related articles with the key words of“stem cell, osteoarthritis, bone metabolism, bone marrow mesenchymal stem cells”in English or in Chinese, respectively. The word“AND”was used for the connection between the word retrieval. Literatures related to stem cells treatment for osteoarthritis were selected;in the same field, the articles published lately in authoritative journals were preferred.
RESULTS AND CONCLUSION:A total of 79 literatures were primarily selected, and 50 documents were involved for summary according to inclusion criteria. The stem celltreatment for osteoarthritis is realized mainly by promoting the repair of cartilage tissue. Commonly used methods are stem celltransplantation and induced differentiation of stem cells. Stem celltreatment has broad application prospects for the treatment of osteoarthritis.

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.

Assessing the stage of live fibrosis and cirrhosis has direct clinical implications for patient treatment options.Liver biopsy is typically considered as the gold standard, but it has limited clinical utility due to its invasiveness.In recent years, with the rapid development of CT hardware and software, CT has made important progress in the non-invasive evaluation of liver fibrosis and cir-rhosis at home and abroad.This review focuses on clinical application of of contrast-enhanced CT, CT perfusion imaging, dual-energy CT and CT molecular imaging for liver fibrosis and cirrhosis.

Pelvic exenteration,first line salvage therapy for selected recurrent cervical cancer patients,is accompanied by a high operative mortality and loss of structure and function of pelvic organs.Advances in radiation therapy,especially 3-dimensional brachytherapy and stereotactic body radiotherapy,provide the opportunity to achieve similar efficacy of pelvic exenteration with acceptable complications and protect the structure and function of pelvic organs.
