But the informatization of health appropriate technologies lags behind and is still at a preliminary stage.As the network of Zhejiang basic health appropriate technologies has been estabished,this paper discusses some issues related with the informatization of health appropriate technologies.

BACKGROUND:The infection after spinal internal fixation was its serious complications. A number of studies have shown that erythrocyte sedimentation rate and C-reactive protein are of great importance in judging infections. OBJECTIVE:To analyze the trend of change of erythrocyte sedimentation rate and C-reactive protein for patients without infection after the cervical fixation. METHODS:Total y 56 patients, who underwent cervical fixation from October 2013 to July 2014, were retrospectively analyzed, and then divided into anterior cervical group (n=29) and posterior cervical group (n=27). Patients in the anterior cervical group underwent anterior cervical decompression bone graft internal fixation. Patients in the posterior cervical group underwent posterior cervical unilateral open door decompression internal fixation. The peripheral blood was col ected before fixation and at the early morning of the 1, 3, 6, 9 days after fixation. Erythrocyte sedimentation rate and C-reactive protein values were determined. The fol ow-up of patients was more than one year. Signs of infection did not appear. RESULTS AND CONCLUSION:(1) General rule:After the cervical fixation, the erythrocyte sedimentation rate was increased significantly and reached a peak on postoperative day 6. The peak level gradual y decreased but has not returned to normal at the 9 postoperative days. The C-reactive protein increased significantly on the first postoperative day and reached a peak on postoperative day 3. The peak level rapidly decreased but has not returned to normal at the 9 postoperative days. The level of erythrocyte sedimentation rate of patients in the posterior cervical group was significantly higher than that in the anterior cervical group at 3, 6 and 9 days after internal fixation (P<0.05). There was no significant difference in the C-reactive protein between these two groups (P>0.05). (2) These results demonstrate that C-reactive protein is an important indicator of monitoring the inflammatory response of patients after cervical internal fixation, which was conductive to the judgment of early infection after internal fixation. The abnormal inflammatory indices of erythrocyte sedimentation rate and C-reactive protein do not suggest a presence of blade infection after internal fixation. C-reactive protein can reach the peak at 3 days after fixation. It is recommended to check blood at 2 and 3 days. If there is no apparent rebound, then the possibility of infection is smal . It may indicate the presence of infection if the inflammatory indices increased again or decreased slowly after the decrease.

Objective To discuss the CT characteristics of AIDS's brain common disease,so that to improve the diagnostic level.Methods CT features of brain lesions in 25 patients with AIDS were retrospectively analyzed.Results Acute HIV encephalitis(n=6),CT features included low density at the basis festival area and the ventriculi laterals,no enhancement on contrast-enhanced scan in 1 case.Subacute HIV brain illness(n=5),CT images showed different degree of atrophy.Toxoplasmosis(n=4),CT images showed iso-dense tubercles with edema in the deep part of brain white matter or iso-dense circle at the edema area.Cytomegalovirus encephalitis(n=3),CT images showed symmetrical low density at bilateral cerebral occipital lobe,internal capsule and thalamus.Progressive multifocal leukoencepathy(n=3),CT showed multiple low density at the inferior surface of brain cortex,the gyri close of focus was clearer,and far of tapetum room system.Mixed infectious(n=4),mixed CT characteristics.Conclusion CT is beneficial in the differential diagnosis of brain disease in AIDS.
