Objective To explore the clinical process and prognosis of middle and intermediate uveitis in children and adults.Methods A total of 121 patients with intermediate uveitis admitted to our hospital from January 2012 to December 2014 were enrolled in the study.Among them,there were 67 cases with monocular involvement and 54 cases with binocular involvement;59 cases were children and 62 cases were adults.All subjects were treated with personalized regimen according to the severity of the disease.The treatment effects and prognosis were compared between patients with different ocular involvement,children and adults.Results The total effective rate of treatment in patients with monocular involvement,children,patients with binocular involvement and adults were 92.5％,93.2％,92.6％ and 91.9％,respectively (all P ＞ 0.05).There was no significant difference in acute phase protein and visual acuity between the patients with ocular involvement and children,adults before treatment (all P ＞ 0.05),and there was no significant difference in the indexes between two groups after treatment (all P ＞ 0.05).The acute phase protein in each group after treatment was decreased,and the visual acuity was obviously increased,there were statistical differences before and after treatment (all P ＜ 0.05).Conclusion Individualized treatment regimen for patients with intermediate uveitis can improve the therapeutic effect,control inflammation and improve visual acuity.The curative effect is not significantly related to age and degree of ocular involvement.

The preliminary results of inactivation of model parvovirus M13Mp 18 in plasma by long-waveUVA irradiation combined with psoralen derivatives were described.At 8-MOP concetration of300?g/ml plasma and UVA intensity of 11.5mW/cm~2,the UVA irradiation for 30～120 min couldresult in virus inactivation of 10~(5～9) infectious dose/ml.Quenchers were used to reduce the damage ofUVA to proteins in order to improve the clotting factor recovery after irradiation.2mmol/Lglutathione,or 2mmol/L glutathione with 2 mmol/L mannitol could significantly improve the Frecovery after irradiation.

Objective To investigate the effect of melatonin on serum malondialdehyde (MDA), NF-κB, tumor necrosis factor-α(TNF-α) andβ2-microglobulin (β2-MG) levels in secondary brain damage following intracerebral hemorrhage patients.Methods 90 patients secondary brain damage following intracerebral hemorrhage were divided into experimental group and control group, 45 cases in each group.The control group were given conventional treatment after surgical removal of hematoma, and the experimental group, on the basis of control group, were given melatonin capsule (6 mg melatonin) , orally, once a day, for 2 weeks treatment.The levels of MDA, NF-κB, TNF-αand β2-MG in patients’ serum were detected.Results The MDA, NF-κB, TNF-αand β2-MG levels after treatment significantly decreased compared with before treatment in two groups (all P<0.05), and the above indexes in experimental group significantly decreased compared with control group ( P <0.05 ).Conclusion Melatonin can significantly reduce the levels of MDA, NF-κB, TNF-αand β2-MG levels in brain injury patients with cerebral hemorrhage, and repair brain damage, which has a guiding significance for clinical use.

BACKGROUND:The post space cleaning using ultrasonic file can improve the bonding strength of fiber postscemented with the self-adhesive resin cement, but the effect on apical sealing ability is stil unclear. OBJECTIVE:To evaluate the effect of the post space cleaning using ultrasonic file on apical microleakage fol owing treatment with two kinds of root canal sealers at two different residual lengths of root canal fil ing. METHODS:Eighty extracted human maxil ary anterior teeth with single-rooted canal were selected, and equivalently randomized into groups A and B (n=40 per group), fol owed by fil ed with Cortisomol or AH-plus, respectively. Groups A and B were randomly subdivided into four groups according to the residual length of root canal fil ing and with or without ultrasonic cleaning (n=10 per group):A1, B1 groups:residual 5 mm, no ultrasonic cleaning;A2, B2 groups:residual 5 mm, ultrasonic cleaning;A3, B3 groups:residual 3 mm, no ultrasonic cleaning;A4, B4 groups:residual 3 mm, ultrasonic cleaning. Subsequently, the apical microleakage was measured using dye method and transparent specimen technique under stereomicroscope. RESULTS AND CONCLUSION:The apical microleakage of each group was as fol ows:A1 (0.73±0.21) mm, A2 (1.37±0.55) mm, A3 (1.18±0.36) mm, A4 (2.05±0.62) mm, B1 (0.34±0.18) mm, B2 (0.47±0.14) mm, B3 (0.59±0.23) mm, B4 (1.39±0.50) mm. The three-factor analysis of variance revealed that the ultrasonic cleaning, root canal sealers and residual length of root canal fil ing al had a significant effects on the apical microleakage (P<0.05), and there were significant differences in the apical microleakage between groups A1 and A2, groups A3 and A4, groups B3 and B4, groups A2 and A4, groups B2 and B4 (P<0.05). These results indicate that the ultrasonic cleaning increases the apical microleakage fol owing the use of Cortisomol at 5 and 3 mm residual length, as wel as the use of AH-Plus at 3 mm residual length. Moreover, for the same root canal sealer, the longer residual length of root canal fil ing indicates, the less microleakage after ultrasonic cleaning.

BACKGROUND:The power output of the human joints depends on the activation of agonists and antagonist muscles around the joints, and the antagonist muscle is involved in physical activity in a co-activated manner, thereby helping to maintain joint stability. But there are less reports on the central nervous system strategies of antagonist co-activation under different muscle contraction modes. OBJECTIVE:To observe the characteristics and differences of surface electromyography (sEMG) of agonists and antagonist muscles of the knee joints during maximal and submaximal isokinetic exercises until fatigue. METHODS:Sixteen students were enroled, who developed the right knee joint fatigue induced by the Biodex isokinetic equipment, and simultaneously sEMG activities of vastus medialis, vastus lateralis and biceps femoris were recorded by the myoelectrical equipment. The RMS (%) and mean frequency were selected to analyze sEMG characteristics. RESULTS AND CONCLUSION:In the maximal isokinetic fatigue, the peak torque was decreased by 40.3% (P < 0.05) and the sEMG activity of agonists gradualy increased and then declined, but the sEMG activity of antagonists kept constant. In the submaximal isokinetic fatigue, the peak torque was decreased by 40.0% (P < 0.05), the sEMG activity of agonists gradualy increased (P < 0.05), and however the sEMG activity of the antagonists initialy increased and then decreased. The RMS and mean frequency of vastus medialis and lateralis as antagonists at selected reciprocal contractions showed no significant changes (P > 0.05). These results suggest that in the different intensities of isokinetic fatigue, the central nervous system employs different neural strategies on agonists and antagonists.

The prevalence rate of diabetes is continuously increasing in China, and diabetes characterizes as high morbidity, low diagnostic rate, low cure rate, and low good control rate, which consequently resultes in the occurrence and progression of various diabetic complications and dramatically decreases the quality of life as well as the survival of diabetic patients.So it is crucial for clinician to screen diabetes early, make the diagnosis early, and start the treatment promptly.This article systemically summarizes the clinical manifestations, diagnostic criteria, typing, pathophysiology, complications, and management of diabetes.

Early gastric cancer is the gastric cancer limited to mucosa or submucosa no matter there is lymph node metastasis or not,and its prognosis is relatively good. China is the high morbidity area of gastric cancer,most patients with gastric cancer are diagnosed at an advanced stage losing the chance of operation and the survival rate is low. Therefore, early diagnosis and treatment is crucial for improving the survival rate of patients with gastric cancer. This article reviewed the progress in study on diagnosis of early gastric cancer from the following aspects:serology,imaging,endoscopy and genetics.

Objective To study the effect of caveolin-1 on renal injury and the expression of tight junction proteins in MRL/lpr mice kidney.Methods The mice were divided into 4 groups:5 mice in the normal control group (BALB/c mice);the MRL/lpr lupus mice (n=18) were randomly divided into the MRL/lpr group in which 6 mice were included;the negative control group in which 6 mice were included;the caveolin1 transfection group in which 6 mice were included.The changes of urine protein,the levels of urea (BUN) and creatinine (Cr) were detected.The expressions of claudin-5,occludin,ZO-1 and caveolin-1 protein were determined by western bloting.Analysis of variance was used to determine statistical significant differences between the two groups.A significance level of 0.05 was considered as signigicant.Results Compared with the control group,24 h urine protein [(2 894±437) mg,(412±72) mg],BUN [(8.7±1.5) mmol/L,(6.9±0.4) mmol/L],Cr [(106±22) μmol/L,(85±4) μmol/L] were significantly increased,level of caveolin-1 protein increased (265±17,61±6),the level of occludin (114±12,190±12),claudin-5 (60±5,80±6) and ZO-1 (98±11,206±15) protein decreased in the MRL/lpr group (P＜0.05).After caveolin-1 transfection,the levels of urinary protein [(1 253±249) mg,(2 894±437) mg],BUN [(6.5±1.3) mmol/L,(8.7±1.5) mmol/L],Cr [(78±17) μmol/L,(106±22)μmol/L] were significantly decreased,and the levels of occludin (218±16,114±12),claudin-5 (87±6,60±5)ZO-1 (313±17,98±11) were increased (P＜0.05).Conclusion The expression of caveolin-1 protein in the renal tissues of lupus nephritis increases.Caveolin-1 can reduce the expression of tight junction proteins and contribute to progres-sion of lupus nephritis.
