Objective:To study the influence of rt-PA and urokinase on the expression of matrix metalloproteinase(MMP-9) and hemorrhagic transformation after thrombolysis therapy in rats.Methods:A focal cerebral ischemia model of rat was established through embolization of left middle cerebral artery with autologous blood clots.rt-PA and urokinase were intravenously administrated 6 hours after ischemia at a dose of 10 mg/kg and 4 000 ?/kg.At the 24th hour after ischemia,all rats were killed.The expression of MMP-9 was detected with immunohistochemical staining and cerebral hemorrhage was quantified by spectrophotometer assay.Results:The expression of MMP-9 was increased after ischemia,and MMP-9 was significantly further upregulated after rt-PA and urokinase had been intravenously administrated.The average optical density(AOD) of MMP-9 in the sham operated group was 0.086?0.008,and increased to 0.158?0.010 after cerebral ischemia for 24 hours and then further increased to 0.225?0.034 and 0.228?0.022 in the rt-PA and urokinase thrombolytic therapy groups.Transformation and quantified intracerebral hemorrhage were significantly higher in the therapy groups as compared with the ischemic group.However,there was no difference between rt-PA group and urokinase group.Conclusion:rt-PA and urokinase treatment both increase the levels of MMP-9 after ischemia.MMP-9 might be involved in the hemorrhagic transformation after thrombolytic therapy with rt-PA and urokinase.

Objective:Evaluate the relationship of complications and indwelling time of double-J ureteral stents after ureterscopic holmium-laser lithotripsy. Methods:170 patients were divided into two groups randomly. groupⅠ(stents indwelling 4 weeks),groupⅡ(stents indwelling 2 weeks).Complications of two groups were compared. Results:During the indwelling time,two groups presented urinary irritative sypmtoms were 81(93%)and 51(61%)P

Objective: Metrological verification for the medical emergency vehicle terminal 3G system, in order to facilitate the accurate positioning, route correctly, timely treatment, high success rate, and increase the credibility and effectiveness of treatment process records provided in the verification process or perform the burden of adducing evidences for emergency first-aid course. Methods:Metrological verification the positioning error, azimuth error and velocity error of emergency medical 3G system terminal. Results:The vehicle terminal measurement device and measurement method, which can satisfy the requirements of verification terminal technology and provide a valid certificate. Conclusion:Metrological verification has the very good function to emergency medical vehicles to successfully treat patients and subsequent verification and perform the burden of adducing evidences.

Objective To present a new seriological method for diagnosing breast carcinoma.Methods Seral anti-p53 antibody was detected with immuno-polymerase chain reation(Immuno-PCR).The expression of p53 in tissue was detected with enzymeimmu-nohistochemistry technique.Results The positive rate of anti-p53 antibody in serum of breast carcinoma was 39.5% and anti-p53 antibody was not found in non-carcinoma and normal controls.The positive rate of anti-p53 antibody was higher than that of non-carcinoma and normal controls(P

OBJECTIVE: To discuss the transnational management strategy of traditional Chinese medicine(TCM) enterprises in China.METHODS: The actuality of the transnational management of TCM enterprises and the main difficulties encountered by them were analyzed.RESULTS: The problems such as foreigners' different opinions on TCM,the laws,intellectual property rights and technology faced by TCM enterprises hindered the practice of the strategy of transnational management.CONCLUSION: The TCM enterprises in China should rely on special advantages in TCM to cultivate the ownership advantages,regional advantage and internalization advantage so as to effectuate transnational management.

OBJECTIVE: To promote Chinese pharmaceutical enterprises to understand their social responsibility clearly and to fulfill it actively.METHODS: The category of social responsibility of pharmaceutical enterprises was analyzed as well as the main approaches to perform corporate social responsibility.RESULTS: Chinese pharmaceutical enterprises should figure out their responsibility to consumers,employees,investors,society,community and other stakeholders.In recent years,the approaches to perform social responsibility based on force system of law and regulations and the improvement of enterprises' consciousness.These are unfavorable to Chinese pharmaceutical enterprises to undertake social responsibility actively.CONCLUSION: There are two approaches to promote Chinese pharmaceutical enterprises to perform their social responsibility,which are external supervision and internal governance.

OBJECTIVE: To study of effects of dexarmethasome of Jianlishu Powder on the release of tumor necrosis factor-? in rats of adjuvant arthritis model. METHODS: Adjuvant-induced arthritis (AIA) was induced by injection of frenndi's complete adjuvant in rats' plantar to observe the effects of Jianlishu Powder on rice' hypersensitivity reaction, thickness of inflamed plantar of both feet, and levels of tumor necrosis factor-?(TNF-?), Interleukin-2 (IL-2) and circulating immune complex (CIC) in AIA rats. RESULTS:rats' right posterior metatarsus which was injected with adjuvant was swollen from the second day for 15 days (primary lesion). Jianlishu Powder significantly inhibited feet swelling induced by collagen dose-dependently and down-regulate the contents of TNF-?,IL-2 and CIC thus resulting in an anti-inflammatory action in AIA rats(P

Acute myeloid leukemia is a disease of malignant clone of the hematopoietic stem cell.The abnormity of molecular biology plays an important role in the pathogenesis of acute myeloid leukemia.More and more molecular abnormalities provide the basis of prognostic evaluation and target therapy.

Objective To compare the efficacy of two different surgery incisions on original corneal astigmatism in cataract surgery. Methods 300 patients (300 eyes) of cataract surgery from August 2012 to August 2013 in our hospital were included in the study,of which 150 patients in the observation group treated with transparent cornea incision in the steep axis of astigmatism,and the control group of 150 pa-tients received lateral ( right) or on the nose by the temporal side ( left) transparent cornea incision. Results In the third day,first month, third month,sixth month and 12th month after surgery,the average corneal astigmatism in the observation group was significantly lower than that before the surgery,which after a month the lowest ( +0. 79 ± 0. 92)D;average corneal astigmatism of patients in the control group were significantly higher than that before the surgery,corneal astigmatism after 3 days to reach the highest,( -5. 65 ± 0. 89)D,3 days after sur-gery,1 month, 3 months, 6 months and 12 months,patients in the observation group were significantly higher visual acuity patients,the differ-ence was statistically significant (P<0. 05). Conclusion Phacoemulsification clear corneal incision along the steep axis IOL implantation for cataract surgery can correct astigmatism original extent a certain extent,and to promote the recovery of visual acuity in patients with a grea-ter degree.

Exterior-and interior-meridian acupoints were used, mainly by selection of local acupoints along meridian. According to the state of disease, electroacupuncture and acupoint injection were combined to treat brachial plexus injury. Among 12 patients, 6 cases were basically cured, 4 cases got effectiveness and 2 cases had no effectiveness. The therapeutic effect of exterior- and interior-meridian acupoints in brachial plexus injury was satisfactory.
