OBJECTIVETo compare the clinical therapeutic effects between ozone and triamcinolone acetonide for the treatment of mild meniscal injury.

METHODSFrom January 2008 to December 2012, 119 patients with meniscal injury diagnosed as type I or II by MRI were divided into three groups. In the triamcinolone acetonide (A) group, there were 38 males and 2 females, with an average age of (25.34 +/- 6.34) years old, ranging from 18 to 48 years old; 36 patients had single knee injuries, 4 patients had double knee injuries and 44 knees with joint effusion. In the ozone (B) group,there were 37 males and 2 females, with an average age of (26.98 +/- 7.20) years old, ranging from 19 to 50 years old; 33 patients had single knee injuries, 6 patiens had double knees injuries and 40 knees with joint effusion. In the combination of ozone and triamcinolone acetonide (C) group, there were 37 males and 3 females,with an average age of (26.44 +/- 6.38) years old, ranging from 18 to 47 years old; 33 patients had single knee injuries, 7 patients had double knees injuries and 39 knees with joint effusion. The patients were treated with injection of 3 mg triamcinolone acetonide alone, 30 ml (30 microg/ml) ozone alone, or both two drugs respectively in knee joint cavity. All the treatment methods were carried out weekly and 4 times injections were required for a treatment course. Knee joint function was evaluated by Lysholm scale and knee joint effusion was examined by MRI before and after treatment.

RESULTSThe scale of knee joint function was 35.68 +/- 4.15 and 65.55 +/- 7.66 in group A, 36.35 +/- 6.83 and 74.39 +/- 8.47 in group B, 36.62 +/- 6.03 and 95.47 +/- 4.78 in group C before and after treatment. Compared with that before treatment, the total scale of knee joint function improved after treatment in every group. The total scale of group C was better than that of the other groups after the treatment,but there was no significant difference between group A and group B. The effective rate of these drugson joint effusion was 68.18% in group A, 62.5% in group B and 87.18% in group C. The effect of co-injection on joint effusion in group C was significantly better than that of triamcinolone acetonide or ozone alone, but the difference between group A and group B was not significant.

CONCLUSIONOzone and triamcinolone acetonide are effective in the treatment of mild meniscal injury, which can relieve symptoms and promote the recovery of joint function. Campared with the single injection, the combination of ozone and triamcinolone acetonide is better.

Objecfive To investigate the association between the exon 2,3,4 of MHC class Ⅰ chain-related gene-B(MICB)and ulcerative colitis(UC)in Chinese Han.Methods Using polymerase chain reaction single-stranded conformation polymorphism,allele frequency of MICB exon 2,3 and 4 in 105 patients with UC and 213 age and sex matched healthy controls were genotyped.All of the studied individuals were Chinese Han.Results Allele frequency of MICB 0106 was increased in patients with UC as compared with normal controls(19.0%vs 8.9%,P=0.000,Pc＜0.001,OR=2.402,95%CI:1.488-3.879).The frequency of MICB 0106 was increased significantly in patients with extensive colitis (24.4%vs 8.9%,P=0.000,Pc＜0.001,OR=3.294,95%CI:1.800-6.027),moderate and severe disease(24.1%vs 8.9%,P=0.000.Pc＜0.001,OR=3.294 95%CI:1.893-5.576)and in those with extra intestinal manifestations(20.5%vs 8.9%,P=0.002,Pc=0.012,OR=2.626,95%CI:1.418-4.861).Furthermore,MICB 0106 allele was higher in frequency in the male patients with UC (22.1%vs 8.0%,P=0.001,Pc=0.006,OR=3.276,95%CI:1.737-6.178)and the patients more than 40 years old(28.8%vs 8.3%,P=0.000,Pc＜0.001,OR=4.500,95%CI:2.381-8.504)as compared with healthy controls.Conclusion MICB 0106 allele is positively associated with UC,especially with extensive colitis,moderate and severe disease,presence of extra intestinal manifestations,male gender and age of more than 40 years in Chinese Han in Hubei province.

Pseudorabies virus (PRV) is a swine herpesvirus of the Alphaherpesvirinae subfamily and a pathogen of swine resulting in devastating disease and economic losses worldwide. Cre/loxP site-specific system has the character of site specific, time specific, tissue specific and high efficiency in recombination, which makes this system universal in vivo and in vitro recombination of bacteria, fungus, plants, insects and mammals. A recombinant PRV which contain a loxP site in TK locus by using Cre/LoxP recombinant system was construsted. A pair of primers were synthesized according to the pEGFP-C1 sequence published on GenBank, and were used to amplify the EGFP gene expression cassette with two loxP sites flanking each side. This target gene was cloned into pSKLR, the resulting transfer vector pSKLR-GFP-loxP was then cotransfected into 293T cells with PRV SH strain genomic DNA. The recombinant virus rPRV1 was selected and purified in TK-143 cells by choosing fluorescent expressing plaques. Cre expression vector pOG231 was cotransfected into 293T cells with rPRV1 genomic DNA. The second recombinant virus rPRV2 was obtained, which contains only one loxP site in TK locus. Sequencing results of rPRV2 TK gene indicated that 34bp loxP site was inserted into rPRV2 genome and there were 270bp deletion in TK gene. PCR amplifying different generations of rPRV2 TK gene showed that the mutant was stable when passages in RK-13 cells. TCID_ 50 assay indicated that rPRV2 grows well on RK-13 cells. The LD_ 50 test results on BALB/C mice suggested that the virulence of rPRV2 was reduced. As a conclusion, the report gene GFP expression cassette was removed successfully from rPRV1 genome and only one LoxP site was leaved in rPRV2 genome by using Cre/LoxP recombinant system.

AIM: To systematic review the effectiveness of refractive multifocal intraocular lens ( MIOL ) ReZOOM vs diffractive MIOL ReSTOR in the treatment of cataract.
METHODS: Randomized controlled trials comparing refractive MIOL ReZOOM with diffractive MIOL ReSTOR were identified by searching CENTRAL, MEDLINE, EMbase, WANFANG MED ONLINE, CMJD, SinoMed, and CNKI. Related journals also were hand-searched. Methodological quality of randomized controlled trials ( RCTs ) was evaluated by simple evaluate method that recommended by the Cochrane Collaboration. Data extracted by two reviewers with designed extraction form. RevMan software ( release 5. 2 ) was used for data management and analysis.
RESULTS:A total of 7 trials (846 eyes) were included for systematic review. Subgroup analyses were used according to different model comparison of ReSTOR MIOL. The results showed a significant difference in the mean of the best distance corrected intermediate visual acuity ( BDCIVA) in the ReZOOM MIOL group with WMD=-0.11, 95% CI (-0.16, -0.06) (P<0.0001). It showed a significantly difference in the mean of the uncorrected near visual acuity ( UCNVA ) , complete spectacle independent rate, halo rate and glare rate in the ReSTOR MIOL group with WMD= 0. 09, 95% CI (0. 05, 0. 14) (P<0-00001), WMD= 2. 62, 95%CI (1. 76, 3. 91) (P<0. 00001), WMD=1. 35, 95% CI (1. 15, 1. 60) (P=0. 0004) and WMD=1-29, 95% CI (1. 09, 1. 53) (P= 0. 003). There was no significant difference between the two groups in the mean of the uncorrected distance visual acuity ( UCDVA ) , the uncorrected intermediate visual acuity ( UCIVA) , the best corrected distance visual acuity ( BCDVA ) and the best distance corrected near visual acuity ( BDCNVA ) with WMD-0.03, 95% CI (-0.06, 0.01) (P=0.15), WMD= -0.04, 95% CI (-0. 09, 0. 01) (P=0. 10), WMD= -0. 01, 95%CI (-0. 04, 0-02) (P=0. 55) and WMD= 0. 06, 95% CI (-0. 06, 0. 17) (P=0. 32).
CONCLUSION: Patients implanted with ReZOOM MIOL can provide better BDCIVA; patients implanted with ReSTOR MIOL show better UCNVA, are less likely to appear light halo, glare and other visual adverse reactions; correction in spectacles cases, patients implanted with ReZOOM or ReSTOR MIOL have considerable performances in the far and near visual acuity.

To investigate the effect of flavonoids from Sophora flavescens in aging mice induced by D-galactose and its mechanism. Totally 60 mice were randomly divided into six groups: the control group, the model group, the piracetam group (positive control group) and flavonoids from S. flavescens low, medium and high doses groups. Except for the control group, all of the rest groups were subcutaneously injected with D-galactose (160 mg x kg(-1)) for successively 30 days to establish the sub-acute senescent model. Meanwhile, flavonoids from S. flavescens low, medium and high doses groups were respectively administered with 150, 300 and 600 mg xkg-('1)of flavonoids from S. flavescens for 30 days. The learning and memory abilities of mice were determined by avoiding darkness ex-eriment and jumping stair experiment. The contents of malondialdehyde (MDA) tumor necrosis factor-aα NF-aα the activities of superoxide dismutase (SOD) monoamine oxidase-B (MAO-B) Na'(+)K'(+)-ATPase and Ca2(+ )-ATPase in the brain of mice were deter-ined respectively after the behavioral experiments. The activity of lactic dehydrogenase ( DH) in blood serum was also determined and analyzed by microscope after HE staining to observe the changes in hippocampal organizational structure. Compared with the model group, flavonoids from S. favescens medium and high doses groups showed significantly increases in the latency of avoiding darkness and jumping stair experiments; flavonoids from S. fllvescens low, medium and high doses groups and the piracetam group showed de-reases in the numbers of errors in avoiding darkness experiment; the flavonoids from S. flavescens high dose group and the piracetam group showed reduction- n the number of errors in jumping stair experiment (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens me-ium and high doses groups and the piracetam group showed improvements in the activities of SOD, Na'(+)K'(+)ATPase in the brain of mice and declines in the contents of MDA and TNF-aα the activity of MAO-B in the brain of mice, the activity of LDH in blood serum (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens low, medium and high doses groups and the piracetam group also showed im-rovement in the activity of Ca2(+ )ATPase, with statistical difference from the model group (P <0 . 5 or P <0 . 1). The pathological result showed decreases in the number of cells of hippocampal dentate gyrus area, sparse cell arrangement, incomplete cellular mor-hology, scarce cytoplasm, blurred boundary between nucleus and cytoplasm, nuclei anachromasis, irregular pyknosis and unconspicu-us nucleoli in the model group. Compared with the model group, flavonoids from S. flavescens low, medium and high doses groups and the piracetam group showed improvements in hippocampal organization tissues. Flavonoids from S. favescens can improve the learning and memory ability of senescent mice induced by D-galactose. Its mechanism may be correlated with the enhancement of anti-oxidative actions by lowering TNF-aαcontent, which results in the stability of cell membrane and the reduction in MAO-B activity.

OBJECTIVEHigh-sensitivity C-reactive protein (hs-CRP) may predict the development of type 2 diabetes mellitus (T2DM), metabolic syndrome (MS) and cardiovascular diseases (CVD) in adult, but few reports on relevant studies in children are available. The present study aimed to understand possible correlation between serum hs-CRP levels and some factors of obese children and adolescents with or without impaired glycometabolism.

METHODSSeventy obese children and adolescents (age 8 - 17 years) and 30 non-obese healthy controls (group 1, 20 boys and 10 girls, mean age 12.6 years) were enrolled into this study. The obese individuals were subdivided into two groups according to the results of oral glucose tolerance test: the obese subjects without IGR (group 2, 54 cases, 43 boys and 11 girls, mean age 11.3 years) and the obese subjects with impaired glycometabolism (group 3, 16 cases, 8 boys and 8 girls, mean age 12.8 years). The levels of serum parameters including hs-CRP, glucose, lipid, insulin, C-peptide and whole blood HbA1c were determined. SPSS 10.0 was used for statistical analysis.

RESULTS(1) There was significant increase of serum hs-CRP level in obese children and adolescents, the median was 2.44 (0.01 - 14.6) mg/L; the level of control group was 0.1 (0.01 - 2.1) mg/L. (2) Some of the following parameters, such as fasting plasma glucose (FPG), triglyceride (TG), fasting insulin (FINS), C-peptide (Cp) and insulin resistance index (IRI), were found increased in group 2 and 3 as compared to group 1. When FPG and TG were still in normal range in group 2, the levels of hs-CRP and IRI were significantly higher than those in group 1, the level of hs-CRP was 2.4 (0.01 - 9.0) mg/L. While FPG and TG were abnormal in group 3, the level of hs-CRP was 2.6 (0.1 - 14.6) mg/L, but the difference had no statistical significance. (3) Pearson correlation analysis showed that there was a moderate correlation between serum hs-CRP and BMI (r = 0.414, P = 0.000). There was a low correlation between hs-CRP and waist circumference, hip circumference and waist to hip ratio (WHR). The correlation of serum hs-CRP with blood pressure, TG, cholesterol, high density lipoprotein-cholesterol (HDL-C), HbA1c, FPG, FINS and Cp had no significant deviation. (4) Multiple linear regression analysis showed that body mass index (BMI) was the only indicator which had correlation with hs-CRP.

CONCLUSION(1) There may be a chronic low-grade inflammation and insulin resistance in obese children. (2) The level of hs-CRP might be independently correlated with BMI in children. (3) Hs-CRP and IRI elevated before FPG and TG did, which may suggest that the low-grade inflammation and insulin resistance may be a pathogenic base of DM rather than the outcome of it. (4) The elevation of hs-CRP may help predict impaired glucose and lipid metabolism.
