International Journal of Laboratory Medicine 2009;30(9):841-842
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.

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
6.Clinical study of phacoemulsification in small pupil cataract after filtering operation of glaucoma
International Eye Science 2015;(4):654-655
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.
8.Research on fractal tones generating method for tinnitus rehabilitation based on musical instrument digital interface technology.
Journal of Biomedical Engineering 2014;31(4):888-893
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 Effects of intra articular injection of 153 Sm citrate HA on antigen induced arthritis were investigated to provide the theoretical fundation for its clinical application.Methods Rabbit arthritis was induced by subcutaneous injection of ovalbumin at weeks 2 and 4,and by intra articular injection of it at week 6.The dosage of 1 85?10 7 Bq or 3 7?10 7 Bq of 153 Sm citrate HA was injected separately into a side of knee joint.The severity of arthritis was determined by joint swelling,skin surface temperature,macroscopic and histologic changes in joints when the rabbits were killed at week 9 after establishment of model.Results Both dosages of 153 Sm have an initial pro inflammatory effects during one week after injection,and then resulted in reduction of joint diameter and skin surface temperature. 153 Sm (3 7?10 7 Bq) showed a more alleviation than 153 Sm (1 85?10 7 Bq) in respect of macroscopic and histologic changes.Conclusion Synovectomy with 153 Sm citrate HA is effective for treatment of chronic arthritis with dependence on the doses and deserves further study.

Objective To investigate the characteristics, degradation and biocompatibility of a woven chitosan fiber (CF). Methods Scanning electron microscopic observation, deteronination of density, degree of swelling and tensile strength were performed to characterize the CF. In vitro degradation was observed by immersing CF in buffered aqueous solution of pH 6 containing lysozyme at 37 ℃, while in vivo degradation was studied after intramuscular implantation of CF in rats. Furthermore, rat mesenchymal stem cells were directly cultured on CF to estimate its toxicity. Results The diameter of CF was about 2000?63?m, with a sleek surface. The density and rate of swelling were 1.093?0.27g/cm3 and 2.30?0.21, respectively. The tensile strength was 80.18?1.56MPa. Specific viscosity, measured after the addition of lysozyme to the solution, decreased dramatically within 2 hours compared with that of the control mixture without enzyme. There was obvious inflammatory reaction after intramuscular implantation in the first week after surgery, bat inflammation subsided gradually. Biodegradation was not obvious within 4 weeks, but majority of it was absorbed in twelve weeks. Cells grew well on it with normal morphology, and no inhibition of cell proliferation could be observed. Conclusion Woven CF has a good tensile strength and fairly good biodegradation and biocompatibility, and it can be used in bone and cartilage tissue engineering.
