Objective To investigate the correlation of serum levels of soluble intercellular adhe-sion molecule-1(slCAM-1) and high-sensitivity C reactive protein (hs-CRP) in newborn infants with hypoxic-ischemie encephalopathy(HIE),as well as the clinical significance of the above two indicators in evaluating prognosis and pathogenetic condition, Methods Immunoturbidimetry(ITM) was applied to measuring hs-CRP,and enzyme linked immunosorbent assay(ELISA) was used to detect slCAM-1. Results As compared with those of healthy control group,the serum levels of hs-CRP and slCAM-1 were significantly increased in acute phase group(P＜0.01). However, the serum levels of hs-CRP and sICAM-1 were declined in recovery phase group. No statistical difference was found between recovery phase group and healthy control group(P>0.05). Conclusion Serum slCAM-1 and hs-CRP may be used as useful indicators of prognosis and pathogenetic condition.

Surgery is an important way to treat patients with primary hyperparathyroidism.Recently,conventional bilateral neck exploration is substituted with minimal invasive surgeries gradually due to the development of the technology of pre/intro-operative localization.Video-assisted surgery is one of the minimal invasive surgeries.It includes video-assisted parathyroidectomy and total endoscopic parathyroidectomy.This article summarize the literatures of treatment of primary hyperpatathyroidism with video-assisted surgery in this article.

Objective To evaluate the bridging role of non-bioartificial liver for patients with chronic severe hepatitis B awaiting liver transplantation. Methods The non-bioartificial liver support was used to treat 9 hepatitis B patients with advanced stage liver failure waiting for liver donor in order to correct physiological disturbances and bridge to orthotopic liver transplantation (OLT). Results When the patients were treated with non-bioartificial liver support, the concentrations of serum total bilirubin and total bile acid were decreased dramatically (P

AIM: To investigate the clinical effects of phacoemulsification and surgical techeniques in small pupil cataract after filtering operation of glaucoma.
METHODS: Thirty-six cases ( 36 eyes ) of small pupil cataract after filtering operation of glaucoma were underwent phacoemulsification combined with foldable intraocular lens implantation. Postoperative visual acuity, intraocular pressure filtration bleb and complications were observed. The follow-up time was 3mo.
RESULTS: The preoperative uncorrected visual acuity (UCVA) or best-corrected visual acuity ( BCVA) ≤0. 3 were in all patients. Postoperativerly, the UCVA or BCVA≥0. 3 after 1wk and 3mo were achieved in 23 eyes (63.89%) and 34 eyes (94. 44%). BCVA was <0. 3 in 2 eyes ( 5. 56%) including optic nerve atrophy of one eye and diabetic retinopathy of one eye. All patients were kept the level of normal intraocular pressure and completed filtering bleb, there were no serious complications.
CONCLUSION: Phacoemulsification in small pupil cataract after filtering operation of glaucoma was complex, and reasonable application of operation skills can still achieve better clinical results. The main factor of affecting the visual acuity is pre-existing retinal optic neuropathy.

Tinnitus is a subjective sensation of sound without external stimulation. It has become ubiquitous and has therefore aroused much attention in recent years. According to the survey, ameliorating tinnitus based on special music and reducing pressure have good effects on the treatment of it. Meantime, vicious cycle chains between tinnitus and bad feelings have been broken. However, tinnitus therapy has been restricted by using looping music. Therefore, a method of generating fractal tones based on musical instrument digital interface (MIDI) technology and pink noise has been proposed in this paper. The experimental results showed that the fractal fragments were self-similar, incompletely reduplicate, and no sudden changes in pitches and would have a referential significance for tinnitus therapy.

Objective:To investigate the influences of material properties and damping effect on the dynamic response analysis of human periodontal ligament. Methods: A 3-D finite element model of human teeth and periodontal tissue was built from graphic information obtained by CT scanning. Dynamic analysis was performed to investigate the influence of different damping effects on the stresses of periodontal ligament by the finite element method. Results: (a) No significant difference of stress between small and large deformation assumption was found, the variation was no more than 1.4%.(b) Dynamic response was obtained under ? varies from 0 to 1.2. After one mastication period, the residual stress at interior surface was larger than that at exterior surface, with a maximum value of ? r = 0.34 MPa at labial cervical area. Conclusion: Appropriate assumptions on material properties may reduce the cost of analysis. After one mastication period, some levels of residual stresses are in periodontal ligament and influenced by material damp.

Objectives:To observe the efficacy of enteral nutrition with short peptide elemental diet(Pepti 2000) in patients with gastrointestinal fistulas and evaluate the sensitivity of nutrition associated index in nutrition monitoring. Methods:Ten cases with gastrointestinal fistulas were administered total enteral nutrition(TEN).They received 146 kJ/(kg?d) of non protein calorie(NPC) and 0.25 g/(kg?d) of nitrogen per day. Body weight,serum albumin, transferrin(TFN), prealbumin(PA),fibronectin(FN),triglyceride and cholesterol were monitored on before and 7th and 28th after TEN. Results:Seven days after TEN,serum PA and FN levels rised significantly( P
