Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.

Objective To observe the effect of Valpar 4 system on hand injury. Methods 40 patients with hand injury were randomly divided into control group and observation group with 20 patients in each group. Routine treatment was applied in both groups while Valpar 4 system was added in the observation group. Then total active motion (TAM) of finger joints, Disability of Arm Shoulder and Hand (DASH), and Upper Extremity Function Test (UEFT) were carried out before, 2 weeks and 4 weeks after treatment. Results The TAM improved significantly in the control group 2 weeks after treatment (P<0.001). The TAM, DASH and UEFT improved significantly in the observation group (P<0.001), and the DASH and UEFT were better in the observation group than in the control group (P<0.001). 4 weeks after treatment, the TAM and UEFT improved significantly (P<0.001) in the control group, the TAM, DASH, UEFT significantly improved in the observation group (P<0.001), and were better in the observation group than in the control group (P<0.05). Conclusion Valpar 4 system can effectively improve the TAM of fingers, function of hands and upper limb, especially in terms of activities of daily living of upper limbs.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

Objective To investigate the influence of iodine excess on expression of TRAIl/TRAIL-sR1 in NOD and Balb/c mice and to study the effect of TRAIl/TRAIL-sR1 on the pathogenesis of experimental autoimmune thyroiditis(EAT). Methods Both Balb/c and NOD mice were divided randomly into control and iodine excess group by feeding with water containing no NaI or 0.05% Nal. The mice were sacrificed after 8 weeks. TRAIL and TRAIL-sR1 mRNA levels were detected by RT-PCR. The function, morphology and apoptosis of thyroids were also observed by ELISA and Tunnel stain. Results Treated by HI, enlarged follicles and flattened epithelium by accumulation of colloid were found in thyroids of both NOD and Balb/c mice. But significant lymphoid cell infiltration and local fibrosis were only found in thyroids of NOD HI group. The relative weight of thyroids of NOD mice in HI group[(104.8±14.5)mg/kg]was heavier than that of control group [(71.8±20.4)mg/kg]. The level of TT4 declined in HI group[(30.77±3.59)mmol/L]compared with control group[(36.43±2.66)mmol/L], meanwhile, the level of TSH was higher in HI group[(6.98±0.66)μg/L]than that in control group [(5.55±0.56)μg/L]. The difference being statistically significant(t=7.773,-9.526,-4.458, all P < 0.05). The relative weight of thyroids of Balb/c mice of HI group[(155.8±20.8)mg/kg]also heavier than that of control group [(105.1±22.0) mg/kg]. The level of TT4 droped in HI group [(19.75±3.32) mmoL/L]was higher than that in control group[(23.46±6.21)mmoL/L], the level of TSH in HI group[(4.14±1.71)μg/L]was higher than that in control group[(3.55±1.41)μg/L], the difference being statistically significant(t=7.554,-7.239,3.140, all P< 0.05). A great deal of apoptotie ceils observed in NOD (3.97±0.91) and Balb/c mice (1.05±0.45) by Tunnel stain were greater than control groups (0.21±0.15, 0.10±0.03), the difference being statistically significant in beth of the two species(t=-7.167,-17.772, both P < 0.05). The apoptosis index of thyroid follicular epithelium in NOD was obviously higher than Balb/c(t=-7.625, P<0.05). The level of TRAIL mRNA did not remarkably change in Balb/c between control group(0.000 59±0.000 39) and HI group(0.001 24±0.000 46, t=-1.940, P>0.05), but it increased apparently in NOD mice HI group(0.018 88±0.005 77) than that of control group(0.009 61± 0.00591, t=-2.71, P<0.05). The level of the expression of TRAIL-sR1 mRNA increased in HI groups of NOD (0.000 53±0.000 15) and Balb/c mice(0.000 42±0.000 09) than that in control groups of NOD(0.000 28± 0.000 05) and Balb/c mice (0.000 17±0.000 06) and the differences were statistically significant between the two species(t=3.050,3.990, all P<0.05). The differences of the expression of TRAIL and TRAIL-sR1 mRNA between the two species were significant(t=-3.37,-4.76, all P<0.05). Conclusions Iodine excess induces colloid goiter in beth species of mice and thyroiditis in NOD mice. The increase of TRAIL and TRAIL-sR1 influenced by iodine excess is one of the molecular bases of follicular epithelium apoptosis and inflammation in thyroids. Genetic factor is a key factor in the pathogenesis of thyroiditis.

Objective To investigate the impact of age on patients with metabolic syndrome (MS) and normal persons. Methods Data was gathered from 8280 persons including 4873 males and 3407 females who were randomly selected. All subjects were devided into normal group and MS group. According to the interval of ten years, the subjects were devided into seven age groups, to calculate the difference of impaired fasting glycaemia (IFG) between patients with diabetes mellitus (DM) and normal people, as well as the related portions. Results (1) The risk of IFG and DM appeared to be different among age groups among the target subjects as well as in the normal and the MS groups (P<0.05). (2) Among the whole subjects, the overall prevalence of IFG was increasing with age. The prevalence of DM had an increasing trend with age augment in 20-79 years group, whereas a decreasing trend appeared in people over 80 years of age. (3) For normal persons, the prevalence of IFG and DM were all increasing with age augment in 20-79 years group, and then decreasing with age augment in the over-80-years group. (4)For MS patients, the prevalence of IFG had an increasing trend with age augment in 20-69 years group, whereas a decreasing trend appeared in people over 70 years of age. There was no tendency of variation with age augment in DM.Conclusions (1) For normal persons, high prevalence rates of IFG and DM were correlated to age augment, especially in senior persons. (2) For MS patients, high prevalence of IFG was also correlated to age augment, but no association between prevalence of DM and age augment was seen. (3)Age from 70 to 79 years appeared to be in high risk with MS.

OBJECTIVETo study the expression of P57(kip2) and Maspin in the pathological scar and their possible role in the pathogenesis of abnormal scars.

METHODSImmunohistochemistry integrated image analysis and reverse transcription polymerase chain reaction (RT-RCR) were performed to detect the expression of P57(kip2) and Maspin in hypertrophic scar, keloid, mature scar and normal skin. Statistics was used to analyze the datas.

RESULTSThe expression of P57(kip2) protein was fixed to fibroblast intranuclear in abnormal scar, and the expression of P57(kip2) protein and P57(kip2) mRNA decreased (P < 0.05). The expression of Maspin protein was fixed to fibroblast cytoplasm and intranuclear in abnormal scar, and the expression of Maspin protein and Maspin mRNA decrease, compared with that in normal group (P < 0.05). There was positive correlation between P57(kip2) protein and Maspin protein expression (P < 0.01).

CONCLUSIONSThe decreased expression of P57(kip2) and Maspin in abnormal scar shows that they are cicatrix-related genes. There is a positive relationship between the two genes. It may be one of the mechanisms of pathogenesis of abnormal scar. It makes effect through fibroblasts.

OBJECTIVETo construct recombinant adenovirus containing codon-modified HPV16L1 gene, and evaluate systemic and mucosal immunological responses induced after immunization with the recombinant virus.

METHODSThe recombinant adenovirus rAd-mod.HPV16L1 was constructed by Admax kit. The C57 BL/6 mice were immunized by purified rAd-mod.HPV16L1 through different inoculation routes. The immunological effect was evaluated by testing the specific neutralizing antibodies in sera and vaginal secretions of immunized mice through indirect ELISA and neutralization assay based HPV pseudovirus.

RESULTSThe result showed that intramuscular immunization could induce good systemic immunity, but the mucosal immunity was too weak, and immunization via intranasal route could induce satisfactory immunity both in sera and vaginal secretions, while intravaginal immunization failed to induce any specific immunological responses either in sera or vaginal secretions.

CONCLUSIONThe recombinant adenovirus containing codon- modified HPV16L1 gene was successfully constructed. Immunization through intranasal route could induce satisfactory immunity both in sera and vaginal secretions, while intramuscular immunization could only induce high titer of neutralizing antibodies in sera.

OBJECTIVETo study the expression of galectin 3 (Gal-3) and CD82/KAI1 proteins in non-small cell lung cancer (NSCLC) and the correlation between their expression and clinical significance.

METHODSThe expression of Gal-3 and CD82/KAI1 proteins was detected by immunohistochemistry in 160 specimens of NSCLC and 20 specimens of normal lung tissue.

RESULTSThe positive rates of Gal-3 and CD82/KAI1 proteins in the NSCLC were 63.8% and 37.5%, respectively, the positive rates of Gal-3 and CD82/KAI1 proteins in the normal lung tissue were 25.0% and 95.0%, respectively, and there was a significant difference between the two groups (P < 0.01). The expression of Gal-3 and CD82/KAI1 proteins was significantly correlated with the grade of tumor, lymph node metastasis, and pathological-TNM stages (all P < 0.05). Spearman analysis showed that there was a negative correlation between expressions of Gal-3 and CD82/KAI1 in NSCLC (r = -0.732, P < 0.01). Overexpression of Gal-3 and low expression of CD82/KAI1 were related to poor prognosis: the survival rate was significantly lower in the positive Gal-3 group (survival time: 23.0 ± 17.5 months) than that in the negative group (survival time: 71.6 ± 21.6 months) (P < 0.01). The survival rates of the CD82/KAI1-positive group (survival time: 72.5 ± 19.5 months) and CD82/KAI1-negative group (survival time: 21.6 ± 16.1 months) were significantly different (P < 0.01). Multivariate analysis indicated that pTNM stage and positive expression of Gal-3 and CD82/KAI1 are independent prognostic factors of NSCLC (P < 0.01).

CONCLUSIONSThe expression of Gal-3 and CD82/KAI1 may be related to the initiation, development and metastasis of NSCLC. Combined detection of Gal-3 and CD82/KAI1 has an important role in predicting the progression and prognosis of NSCLC.
