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.

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.

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.

Objective To improve the method for the Word-Stock file update and cancel the Disk P mapping in order to meet the requirements of HIS such as Out-Patient Doctor Workstation system and Nurse system.Methods Two tables were created to store the names,contents and update time of the dictionary,and the word-stock file was built through searching the data of the tables.Results The word-stock file update was improved successfully.Conclusion The new method for the word-stock file update is easy to be achieved so that the program of client can update immediately,which also can get rid of the error and hidden troubles.

This paper analyzed the Chinese Medical Science and Technology Award gained by military health system during 2001- 2009,which showed the importance and necessity of social awards to the military health system.We also discussed the problems including insufficient importance attached by the military health system,inadequate enthusiasm and motivation of individual researchers,uneven distribution of the scientific level,as well as the number of awards and subjects.

Objective To analyze the characteristic and distribution of colonic polyps and investigate the diagnosis of colorectal benign polyps for chromoendoscopy and curative effect of argon plasma coagulation, High frequency electric knife electric coagulation, EMR, Titanium clips treating Colorectal benign polyps.Methods 175 patients of benign colorectal polyps of endoscopic diagnosis combined with pathology and treated were collected from December 2015 to June 2016.Results by ordinary and staining endoscopy, solitary polyp quantity and multiple polyps types in many segments for colon were more. Which the polyps quantity of rectum and sigmoid colon were more and polyp diameter was smaller in the left colon, the polyps quantity of ascending colon were less and polyp diameter was larger in the right colon. Pigment endoscopy was conduce to diagnose the micro-polyp. Chromoscopy enhanced the detection of multiple polyps in the colon.Conclusions Staining endoscopy is improved the multiple polyps detection rate and reduce omission diagnose rate, to proift the differential diagnosis of benign polyps, according to the solitary polyp and multiple polyps combined with polyp size in colon, which select the one of APC, high-frequency electric coagulation electric cut and EMR or two kinds of therapeutic endoscopy, therapeutic endoscopy is efifcacy and safety technique and the most of APC.

Objective:To investigate the relationship between hyper-homocysteinemia ( HHcy) and experiment autoimmune en-cephalomyelitis (EAE) mice,and to study the cause and effect of HHcy in multiple sclerosis (MS).Methods: Four groups were included in this study:healthy C57BL/6 mice and EAE mice fed with chow(HC and EAE group),healthy mice and EAE mice supple-mented with 4%(w/v) methionine in the drinking water (HC+Hcy and EAE+Hcy group).Clinical symptoms,the levels of Hcy and cytokines ( TNF-α,IFN-γand IL-17) were evaluated at different time points.Results:EAE group had no greater Hcy than HC group ( P>0.05 ).The clinical scores and weight loss of mice from EAE+Hcy group were more severe than those from EAE group during the course of EAE ( P<0.05 ).EAE+Hcy group had higher levels of TNF-αand IFN-γthan EAE group ( P<0.05 ) ,while IL-17 was about the same.Conclusion:Mice do not have gradually increased Hcy during the course of EAE.HHcy worsen the symptoms of EAE by pro-moting the production of TNF-αand IFN-γ,but not IL-17.
