Objective To explore the expression of interleukin-8(IL-8) in the brain tissue and serum and effect of Dexamethason in rats with local cerebral ischemic.Methods The rats were randomly divided into blank control group,shamoperated group,ischemic group and Dexamethasone group.The latter two groups were divided into 1 h,2 h,4 h,8 h,12 h,24 h,48 h,72 h after oppration groups,respectively,12 rats in each group.The cerebral ischemical models were made by thread-embolism.The expression of IL-8 in brain tissue and serum at each time point were detected by ELISA method.Results In the ischemic group and Dexamethasone group,the expression of IL-8 of the brain tissue and serum were increased gradually in 1 h after ischemia,and reached the perk in 24 h and 4 h respectively.Which were significantly lower than those in the blank control group or shamoperated group(all P

To investigate the pathogenic mechanism of interleukin 6(IL-6) in the tubulointerstitial lesions of patients with active lupus nephritis(LN). Methods Uninary IL-6 from 42 active LN cases and the renal tissues sections from 15 of them were examined by performing ELISA and in situ hybridization with IL-6 cDNA probe labelled by digoxingenin respectively. Results In 36/42 (85.7%) of active LN patients, uninary IL-6 content was higher than or equal to 5 pg/mg ,cr, while no one case did in normal controls. Uninary IL-6 content was highly correlated with the uninary ft-m and NAG excretion respectively. In normal tubules and interstitium, IL-6 mRNA was undetectable. For all sections from 15 active cases, IL-6 mRNA was found in tubular and interstitial cells, and the distribution correlated with the extent of tubulointerstitial lesions. Conclusion IL-6 is probably involved in tubulointerstitial lesions of patients with active lupus nephritis.

Objective To study and compare the present situation and the difference in subjective well-being between students in junior high schools for the blind and normal junior high school students, and provide basis for the construction of education mode for the well-being of the blind students. Methods By random sampling method, subjective well-being questionnaire was used to investigate the 155 blind students in five blind schools and 436 normal junior high school students in three junior high schools in Shandong Province. Results ( 1 ) The blind students had shown significant differences in many aspects of subjective well-being such as gender, family e-conomic status, sight and parents'education degree (P<0. 05) . (2) Blind school students'social confidence experience (4. 59 ±1.13) was significantly higher than that of the normal students (4.31 ±1.13), and had a significant difference (P<0.05). Blind students got significantly lower scores ((4. 38 ± 1.26) , (4.00 ± 1. 29) ,(3. 58 ± 1. 37) ,(3.89 ± 1. 35) ,(4.41 ± 1.04) , (4. 20 ± 1. 33) ) than normal school students( (4.68 ± 1. 19) , (4. 36 ±1.14),(3.88±1.27),(4.41 ±1.25),(4.61 ±0.99), (4. 52 ± 1. 18)) in target value experience, physical health experience, mental health experience, interpersonal adaptability experience self-acceptance experience, and emotional balance experience. Conclusion There exists a significant difference between the blind students and the normal junior high school students in the different aspects of subjective well-being.

Isopinosine (ISO, 25?100 mg/kg?d-1ip for 4 or 5d) significantly increased the production of serum hemolysin-and spleen plaque forming cell ( PFC) in normal mice immunized with SRBC. The same result was observed in immunosuppressive mice induced by cy clophospha-mide. In 16 month aged mice, ISO (ip for 5 d) showed potentiating effect on anti-SRBC PFC response at the dose of 2 .5 mg/kg, no significant effect at the dose of 5 .0 mg/kg, and inhibiting effect at the dose of 25 and 100 mg/kg respectively. 1SO(25,50 and 100 mg/kg?d-1 ip for 9 or 10 d ) remarkably enhanced delayed cutaneous hypersensiti-vity (DCH) to 2, 4 -dinitrochlorobenzene (DNCB) in normal mice as well as in immunosuppressive mice induced by cyclophospha-mide. ISO (5, 10 and 20 mg/L ) signficantly increased ConA-induced lymphocyte proliferation of spleen cells from C57BL/6J mice in vitro. There was also potentiating effect on lymphocyte proliferation induced by ConA in 16 month aged mice.

OBJECTIVE: To observe the effects of Cili juice enriched with SOD (CLJES) on lead excretion, activity of superoxide dismutase (SOD) in erythrocytes, plasma lipid peroxidation (LPO) and immune function in experimental lead poisoning animals. METHODS: Lead poisoning models were made in rats and mice. The effects of CLJES on lead excretion, SOD activity, LPO concentration in rats and immune functions in mice were determined and compared with those of conventional EDTA treatment. RESULTS: CLJES significantly increased lead excretion. Furthermore it significantly increased SOD activity, reduced LPO concentration in rats with lead poisoning and enhanced immune function in lead loaded mice, however EDTA had no such actions. CONCLUSION: CLJES might exert a wider range of therapeutic effects on lead poisoning than EDTA.

AIM:To evaluate the efficacy and safety of Sub-tenon's anesthesia for compound trabeculectomy with high intraocular pressure.
METHODS: Forty - six eyes ( 46 cases ) of primary glaucoma received compound trabeculectomy under Sub-tenon's anesthesia, whose preoperative intraocular pressure were higher than normal after 24 to 48h of combined medication. Both efficacy and complication of the anesthesia were studied.
RESULTS: One minute after anesthetic injection, all cases were able to achieve the effect of analgesia and eye brake. During the operation, 0 level of anesthesia effect included 35 eyes ( 76%) , 1 level of anesthesia effect included 10 eyes ( 22%) , 2 level of anesthesia effect included 1 eye(2%). Only 1 case of these patients needed to add the surface anesthetic once, and other cases were successfully operatedunder Sub-tenon's anesthesia. The total effective rate was 98%. No anesthesia complications occurred in all cases.
CONCLUSION: Sub - Tenon's anesthesia is safe, effective, simple and quick for compound trabeculectomy with high intraocular pressure.

AIM: To investigate the potential causes and management of the clusters of diffuse lamellar keratitis (DLK) after laser corneal refractive surgery.METHODS: The study enrolled 98 eyes (53 patients) complicated with DLK after receiving laser in situ keratomileusis (LASIK), FS-LASIK or small-incision lenticule extraction (SMILE) in our center from February 10th,2016 to February 22th,2016.They were given clinical classification treatments according to corneal layer inflammatory extent and then followed up after 1, 3, 5, 7, 10d and 1mo.RESULTS: The clusters of DLK occurred 5 times in the study period.The incidence and degree of DLK significantly decreased after changed the sterilization, surgical equipments, temperature and humidity of the operating room.There were 80 eyes (82%) had stage 1 DLK, 11 eyes (11%) had stage 2, 4 eyes (4%) had stage 3 and 3 eyes (3%) had stage 4.The incidence of DLK after FS-LASIK was 40% (79 eyes in 42 patients), that after LASIK assistant by Hastome keratome was 45% (10 eyes in 5 patients), that after SMILE was 20% (9 eyes in 6 patients).After intensive treatment, as glucocorticoid treatment and flap lifting flushing, all cases recovered within 1mo.CONCLUSION: The outbreak of DLK may be associated with the disposable item, flushing liquor, temperature and humidity of the operating room.Early diagnosis, prevention and treatment are the key of decreasing the incidence of DLK.
