ObjectiveTo search for the effect and safety of urokinase (UK) in different dosage on acute cerebral infarction.Methods80 patients suffering from acute cerebral infarction were randomly divided into two groups. Group A received UK 0.75 MU intravenously within 30 min. Group B received UK 1.0～1.5 MU intravenously within 30～45 min. ResultsThe neurological deficits scores was improved in both groups. There was no significant difference between group A and group B(P>0.05). The total effective rate and significant effective rate was 82.5% and 60.0% in group A respectively, but those were 87.5% and 65.0% in group B respectively(P>0.05). More hemorrhage happened in group B. ConclusionThe UK in small dosage is effective and relatively safe in treatment of acute cerebral infarctions.

To assess whether the Shuxuening injection influences liver function, this paper analyzes the hospital information system (HIS) data from 20 national hospitals. The patients were divided two groups: patients (5 353 cases) using Shuxuening injection acted as the exposed group, then the patients (4 863 cases) not using Shuxuening injection acted as the unexposed group. Take the abnormal changes of alanine aminotransferase and aspartate aminotransferase indexes as the result. Control confounding factors by stratification analysis, classic logistic regression analysis, before logistic regression based on propensity score weighting method and logistic regression based on generalized boosted models (GBM) of propensity score weighted combination of covariate adjustment. Then, the study analyzes the effects of Shuxuening injection on liver function by observing the changes of the indexes. Analysis of the impact of parenterally administered Shuxuening on ALT shows that, before logistic regression based on propensity score, then the regression is -0.232 (P value is 0.017). However, after logistic regression based on propensity score method the regression became -0.150 (P value is 0.370). Whereas, analysis of the impact of parenterally administered Shuxuening on AST shows that, before logistic regression based on propensity score, then the regression is -0.034 (P value is 0.767). However, after logistic regression based on propensity score method the regression became -0.091(P value is 0.538). Thus, propensity score method can control a large number of confounding factors, making the results more close to the clinic. Hence, based on existing electronic medical data, this study didn't find that parenterally administered Shuexuening influences ALT and AST.

AlM: To observe the influence on the incidence of diffuse lamellar keratitis ( DLK ) after laser in situ keratomileusis ( LASlK ) whether or not wearing sterile gloves with talc during operation, and to confirm the role of residual talc in the occurrence of DLK.
METHODS: Totally 563 patients ( 1 126 eyes ) accepted operation with the method of surgical hand antisepsis only were set as the experimental group, while 592 patients ( 1 184 eyes ) with the method of surgical hand antisepsis and sterile gloves as the control group. Each patient was rechecked to observe the occurrence of DLK on the first day and the seventh day after the operation. Then the data of DLK were statistically analyzed byχ2 test and rank sum test.
RESULTS:On the first postoperative day, the incidence of DLK was 7. 4% (83 eyes) in experimental group and 12. 2% (144 eyes) in control group. ln the former group, stage Ⅰ of DLK accounted for 4. 6% (52 eyes) and stageⅡ for 2. 8% (31 eyes);while in the latter, stage l did for 7. 7% (91 eyes) and stageⅡfor 4. 5% (53 eyes). On the seventh day, all DLK were cured. The other 2 cases ( 3 eyes) occurred in stage Ⅳ DLK ( the first time recheck was on the eighth day after operation and fluorometholone ophthalmic solution was not used on time ) . The incidence and the severity were both significant lower in the experimental group than in the control (both P<0. 01).
CONCLUSlON: Talc is one of the most important factors resulting in DLK after LASlK. The method of surgical hand antisepsis without wearing gloves could avoid the stimulation of talc and reduce the incidence of DLK obviously.

Objective To investigate the kinetic changes of inflammatory cell infiltration and thyroid autoantibodies in the development of iodine-induced autoimmune thyroiditis in NOD.H-2~(h4)mice.Methods Either 128 five-week-old NOD.H-2~(h4)mice or 128 Kunming mice were randomly divided into two groups,and received plain water or water containing 0.05% sodium iodide.At the time points of 1,2,4,8,12,16,and 24 week after receiving iodinated water,mice were anesthetized by diethyl ether and bled from eye socket vein,and their thyroid glands were collected.Indirect ELISA method was used to measure the levels of serum thyroglobulin autoantibodies (TgAb)and thyroid hormone.After being fixed with paraformaldehyde and embedded in paraffin,thyroid sections were stained with HE and used for morphometrieal analysis.Results In the iodine treated group of NOD.H-2~(h4) mice,autoimmune thyroiditis was observed as early as 1 week after they began receiving indinated water.The prevalence as well as the degree of autoimmune thyroiditis reached the maximum at 12 weeks and remained until 24 weeks.Serum TgAb level increased after 8 weeks of iodine ingestion in NOD.H-2~(h4) mice,then increased steadily throughout the 24 weeks of experiment.On the contrary,serum TgAb was not increased in the control group of Kunming mice.Conclusion Iodine may induce and exacerbate lymphocytic infiltration of the thyroid in genetically susceptible NOD.H-2~(h4) mice,and serum TgAb is just a marker of autoimmune thyroiditis.

Aim To investigate the role of captopril in insulin resistance of endothelial cells induced by high glucose.Methods 1 .Improvement effect of captopril on insulin resistance in HUVECs was observed.The HUVECs were seeded in a 6-well plate and were ran-domly divided into 5 groups,namely,control group, IR group,IR together with different Cap concentrations (low,medium and high concentration),respectively. 2.Improvement effect of Cap on insulin resistance was mediated by PPARγin HUVECs.HUVECs were ran-domly divided into 6 groups,namely,control group, control +PPARγinhibitor (PI)(1 .0 μmol · L -1 ) group,IR group,IR +PI(1 .0 μmol·L -1 )group,IR +Cap(1 ×1 0 -5 mol·L -1 ) group,and IR +Cap +PI (1 .0 μmol·L -1 )group.All indicators were detected. Results After HUVECs were incubated with media containing 33 mmol·L -1 of glucose for 48 h,the NO levels were significantly decreased while ET-1 levels were significantly elevated,showing a significant differ-ence between IR group and control group (P <0.01 ). The expression levels of PPARγmRNA and its protein were somewhat up-regulated,but there was no signifi-cant difference between IR group and control group (P>0.05).When the HUVECs in IR group were treated with DMEM containing glucose (33 mmol·L -1 )for 48 h and insulin for 30 min,the expression levels of PPARγmRNA and its protein in Cap groups were simi-lar to those in the IR group,and there was no signifi-cant difference between the two groups (P >0.05 );however, the expression levels of phosphorylated PPARγprotein in Cap groups were increased compared with IR group (P <0.05).The levels of NO were sig-nificantly increased whereas the levels of ET-1 were decreased in Cap groups,which had significant differ-ences compared with IR group (P <0.05).Nonethe-less,pre-treating with GW9662,a PPARγinhibitor, the improvement effects of Cap were markedly abol-ished.Conclusions Captopril could improve high glucose-induced insulin resistance of endothelial cells mediated by PPARγ,and the underlying mechanisms are related to the activation of PPARγ,rather than its expression.

Objective To study the diagnosis and treatment of malignant renal angiomyolipoma with metastases. Methods Three cases of advanced malignant renal angiomyolipoma with metasta-ses were retrospectively reviewed. Case 1 was a 55-year-old woman presenting with recurrent low-grade fever and aching pain in left flank. Ultrasound showed solid mass in the left kidney. Left radical nephrectomy was then performed. The right pulmonary lobectomy of the inferior lobe and wedge ex-section of superior lobe was performed 7 years later because of multiple pulmonary metastases. Case 2 was a 37-year-old woman. Left nephrectomy was performed because Ultrasound and CT showed left kidney solid mass. Six years later, multi-site metastases were found in liver and retroperitoneum and mestastasis tumors were resected. At 10 years after the primary diagnosis, CT showed multi-metasta-ses in liver and retroperitoneum. The retroperitoneal masses were resected and liver lesions were trea-ted by radiofrequency ablation. Case 3 was a 34-year-old man presenting with swelling pain in right flank. CT scan showed a lesion in the right kidney and right radical nephrectomy was performed. Four months after the surgery, MRI revealed multiple liver and retroperitoneal nodules. All the 3 cases had not been diagnosed with tuberous sclerosis and did not accept chemotherapy. Results The cut sur-face of the lesions was red-brown and yellow and the texture was tender. Under microscopic examina-tion, the tumors of case 1 and case 3 were composed of sheets or nests of large polygonal epithelioid cells. It revealed that occasionally clear cytoplasm with abundant eosinophilic, prominent nucleoli, and multinucleated and markedly pleomorphic form. Necrosis was presented as well. Large areas of case 2 tumor were made up of spindle smooth-muscle cells, adipose tissue, thick-wall blood vessels and some areas merged with a proliferation of epithelioid which was consistent with typical angiomyolipoma. Im-munohistochemical study showed that the epithelioid cells and spindle smooth-muscle cells were posi-tive for VM, HMB45, Melan-A and negative for S100, CK. Case 1 and case 3 were diagnosed with malignant epithelioid angiomyolipoma, while case 2 was diagnosed with malignant classic angiomyoli-poma and epithelioid in part of the tumor. Case 1 was well alive. Case 2 was alive with tumor 12 years after the diagnosis. And case 3 was missed in the follow-up 3 months after metastasis resection. Conclusions Malignant renal angiomyolipoma is a rare disease. The diagnosis depends on histopatho-logic, immunohistochemieal study and clinical follow-up. Radical resection of the primary, recurrent and metastatic tumors is the main therapy. It needs more research to clarify if metastasis has any effect on prognosis.

Background C57BL/6(B6) is a kind of routine mouse specie used in experimental autoimmune uveitis (EAU) research.Previous studies showed that the pathogenesis of uveitis related to inflammatory cytokines secreted by different helper T(Th) cells.However,the interaction of different Th cells in EAU is unclear.Objective This study was to investigate the dynamic changes of inflammatory factors in the spleen and serum after immunization in EAU mice.Methods Forty-four SPF B6 mice were immunized by injection of interphotoreceptor retinoid-binding protein (IRBP) and complete Freund adjuvant (CFA) emulsion via caudal vein and footpad.Indirect ophthalmoscope was used to examine the eyes 3 times per week and the inflammatory response was scored based on Thurau's criteria.In the thirty day after injection,20 model eyes were extracted and the sections of eye tissue were prepared for histopathological examination.The spleens of model mice were enucleated before injection and 2,5,10,15,20,25,30 days after injection,and reverse transcriptase PCR (RT-PCR) was used to detect the contents of interleukin-17 (IL-17) mRNA,interferon-γ (IFN-γ) mRNA,tumor necrosis factor-α (TNF-α) mRNA and IL-10 mRNA,and the contents of IL-17,IFN-γ,TNF-α and IL-10 in model serum were assayed by ELISA in 24 model mice.The experimental protocol and use of the animals were approved by Ethic Committee for Care and Use of Laboratory Animals of Shandong University of Traditional Chinese Medicine.Results Mild inflammatory response was seen in 12 days under the indirect ophthalmoscope with the scores of 0.5.The inflammatory scores peaked in 13-15 days with the scores of 1.0 and alleviated after that with the inflammatory scores of 0.5 in 30 days after injection.The histopathological score was consistent with the clinical score in the models on the 30 days.The serum IL-17 content of model mice was (0.98±0.05) ng/L before injection and increased to (51.85 ±2.42) ng/L on the fifth day,and decreased to (4.01±0.06)ng/L on the fifteen day.But,the serum IL-17 level increased to (25.00±0.94)ng/L again on the 25th day,and then lowed to (6.01 ±0.21)ng/L 30 days after injection,showing a significant elevation in comparison with that of before injection (P=0.000).The serum IFN-γ content of the model mice was (1.02±0.09)ng/L before injection and increased to (50.54±0.48) ng/L on the fifth day,and (73.21±0.12) ng/L on the tenth day,and then it declined gradually until (5.15±0.18)ng/L in the 30th day,which was still higher than that of before injection (P=0.000).After injection of IRBP+CFA,the serum TNF-α level upregulated from the second day to fifth day with the peak values (134.25±0.59)ng/L,and declined to valley on 15th day.A repeat elevation of serum TNF-α level was found on the 20th day with the values (60.54±0.62)ng/L and followed by decrease till the 30th day,which was higher than that of before injection (P=0.660).Serum IL-10 was detectable in the tenth day and peaked on the 15th day.Then a slight decrease was seen till the 30th day,compared with before injection(P =0.000).The contents of IL-10 mRNA,IL-17 mRNA,TNF-α mRNA,IFN-γmRNA in mice spleens followed the same pattern with serum levels of their proteins.Conclusions IL-17,IFN-γ,TNF-α and IL-10 are key inflammatory factors of Th1,Th2 and Th17,they present with specific changes during EAU,it confirming that IFN-γ probably play a pathogenic role in EAU,IL-17 and TNF-α levels probably associated with the chronic and recurrent procedure of uveitis,IL-10 plays an inhibit role in EAU.
