Chondroitinase has been used as an important tool in the study of the structure, function and distribution of glycosaminoglycans for many years. Recently, the enzyme has been reported to be a potential enzyme for chemonucleolysis, an established treatment for intervertebral disc protrasion. In this paper, a chondroitinase had been purified from the culture supernatant of Aeromonas sobria YH311 using a simple purification procedure of ammonium sulfate precipitation, QAE-Sephadex A50 ion exchange chromatography and Sephadex G-150 gel filtration. The immobilization of purified chondroitinase using sodium alginate or cellulose as carriers has also been studied. The chondroitinase obtained from Aeromonas sobria YH311 was purified 55-fold to 95.3% pure, the specific activity of the purified enzyme was 31.86u/mg and the yield was 37%. The molecular weight of chondroitinase from Aeromonas sobria YH311 was determined by SDS-PAGE to be 80kD, which was almost the same as those chondroitinase AC from Arthrobacter aurescens, Aeromonas liquefaciens and Flavobacterium heparinum. But its isoelectric point was 4.3 - 4.6, which was far lower than the microbial chondroitinase AC. After the immobilization on sodium alginate or cellulose, the properties of chondroitinase changed greatly. The optimum temperature and pH of the free enzyme were 50 degrees C and 7.0 respectively, and about 10% activity remained after heat treatment at 80 degrees C for 20 minutes, and 47% activity remained after two weeks storage at 4 degrees C. The chondroitinase immobilized on sodium alginate had the optimum temperature and pH of 40 degrees C and 7.0 respectively, about 50% activity remained after 80 degrees C heat treatment for 120 minutes and 50% remained after 30 days storage at 4 degrees C. The chondroitinase immobilized on cellulose had the optimum temperature and pH of 70 degrees C and 6.0 respectively, and more than 70% activity remained after heat treatment at 80 degrees C and 30 days storage at 4 degrees C. The yield of the immobilization was very low, with 18.56% for alginate and 18.86% for cellulose.

Abstract?AIM:To investigate the effective treatment methods of corneal injury caused by chestnut thorns and the factors affecting the disease progression.?METHODS: From Jul.2014 to Oct.2015, the clinical data of 15 patients(15 eyes) with corneal injury caused by chestnut thorns in Ophthalmology Inpatient Department of Wuhan Tongji Hospital was retrospective analyzed. The patients without fungal keratitis were treated with the surgery of removing chestnut thorn from cornea and antifungal drugs. For the patients complicated with fungal keratitis, besides surgery of removing chestnut thorn and antifungal drugs, anterior chamber irrigation and corneal stroma injection with fluconazole solution were given to treat the disease.If necessary, amniotic membrane transplantation or keratoplasty was also given to the patients complicated with fungal keratitis. After that, the effectiveness of those methods and the factors affecting progression were analyzed.?RESULTS:For 11 patients without fungal keratitis, the average time between corneal injury and receiving treatment at Tongji Hospital was 1-7 (2.42±2.15) d and for 4 patients complicated with fungal keratitis, the average time was 3-30 (18.25±4.35)d.Among 15 cases, statistics suggested that the average number of chestnut thorn in patients complicated with fungal keratitis was 4.5, and all the chestnut thorn penetrated the cornea into the anterior chamber.The average number of chestnut thorn in patients without fungal keratitis was 3.5, and the proportion of chestnut thorn penetrated the cornea into the anterior chamber was 28.5%.After treatment, all patients had no new fungal keratitis or other complications.Those results indicated that the different treatments for the patients with or without fungal keratitis were all effective.?CONCLUSION:The factors affecting the progression of cornea foreign body injury caused by chestnut thorn are the number of chestnut thorn, whether chestnut thorn penetrate the cornea into the anterior chamber, time since injury, active anti -fungal therapy. If patients complicated with fungal keratitis could be treated with antifungal agents and anterior chamber irrigation or corneal stroma injection using fluconazole solution without delay, the progress of fungal keratitis could be effectively controlled, and favorable conditions for further therapy such as amniotic membrane transplantation or keratoplasty could be provided.

OBJECTIVETo investigate the effects of non-surgical periodontal therapy on serum inflammatory factors and metabolism levels in obese rats with experimental periodontitis.
METHODSSixteen obese rats with experimental periodontitis were randomly divided into treatment group and control group with non-surgical periodontal therapy and no treatment, respectively. Oral glucose tolerance test was performed before treatment and 2 weeks after the treatment. All the rats were sacrificed 2 weeks after treatment and the orbital vein blood was taken to detect fasting blood glucose, fasting insulin, and serum level of C-reactive protein (CRP). Results Two weeks after periodontal treatment, fasting blood glucose (t=2.445, P=0.034) and beta cell function index (t=-2.543, P=0.027) were significantly lower in the treatment group than in the control group. Compared with those in the control group, CRP level (t=2.388, P=0.028) and the area under the curve in the oral glucose tolerance test (t=12.053, P=0.000) decreased significantly in the treatment group.
CONCLUSIONNon-surgical periodontal treatment can reduce serum CRP level and improve glucose metabolism in obese rats.

AIMTo examine the impact and prognostic significance of alpha-tocopherol associated protein (TAP) expression in a series of prostate cancer patients.
METHODSTissues from 87 patients underwent radical prostatectomy were examined for TAP expression by immunohistochemistry. The relationships of the staining results, the clinic pathological characteristics and the recurrence times were analyzed.
RESULTSCompared with the adjacent areas of normal and benign glands, immunoreactivity of TAP was reduced in areas of prostate cancer. A lower TAP-positive cell number per mm(2) of the largest cancer area (defined as TAP-PN) was associated with higher clinical stage (r = -0.248, P = 0.0322). Inverse associations were found among the TAP-PN and positive lymph nodes (r = -0.231, P = 0.0325), preoperative prostate-specific antigen (PSA) levels (r = -0.423, P = 0.0043), tumor size (r= -0.315, P= 0.0210) and elevated tumor cell proliferation, which was indicated by the staining of Ki-67 (r = -0.308, P = 0.0026). TAP-PN was a significant predictor of recurrence univariately (P = 0.0006), as well as multivariately, adjusted for known markers including preoperative PSA, clinical stage, Gleason score, surgical margin, extra-prostatic extension, seminal vesicle invasion and lymph node metastasis (P = 0.0012).
CONCLUSIONReduced expression of TAP was associated with the cell proliferation status of prostate cancer, adverse pathological parameters and the increased risk of recurrence.

OBJECTIVETo investigate the effect of periodontal therapy in controlling periodontitis and on insulin resistance and lipid metabolism in obese rats with periodontitis.
METHODSSprague-Dawley rats were randomized into normal group (group C), obese group (group O), periodontitis combined with obesity group (group P) and periodontal treatment group (group T). The obese rats in groups P and T were subjected to ligation of the maxillary second molar with silk thread to induce experimental periodontitis, and the rats in group T received periodontal therapy after the ligation. All the rats were sacrificed at the age of 24 weeks for measurement of blood lipids, insulin and blood glucose levels, and insulin resistance index (HOMA-IR) was calculated. The expressions of insulin receptor substrate-1 (IRS-1) and IRS-2 in the liver tissues were detected using real-time quantitative polymerase chain reaction (RT-PCR).
RESULTSCompared with the obese rats in group O, the rats in group P showed significantly higher HOMA-IR and LDL-C and lower expressions of IRS-1 and IRS-2 mRNA expression and HDL-C level (P<0.05). Compared with those in group P, the mRNA expressions of IRS-1 and IRS-2 and HDL-C level were significantly increased and LDL-C level, TC level and HOMA-IR were all decreased in group T (P<0.05), but the level of TG was comparable between the two groups. Pathological examination revealed lessened inflammatory cell infiltration and tissue destruction in the upper jaw of the rats in group T; the rats in group P presented with the most obvious upper jaw destruction and steatosis and inflammatory cell infiltration in the liver.
CONCLUSIONPeriodontal inflammation can downregulate the expression of IRS-1 and IRS-2 and increase insulin resistance and dyslipidemia in obese rats. Periodontal therapy produces a beneficial effect in improving insulin resistance and reducing dyslipidemia in obese rats.
