Objective To study the clinical efficacy,safety,and economic efficiency of ginkgolide injection and conventional therapy of patients with cerebral arterial thrombosis in multi center,and to evaluate the economic value of drugs.Methods A prospective cohort study was conducted in this study,patients with ischemic stroke were collected from August 2013 to December 2014.Patients (354 cases) in treatment group were treated with Ginkgolide Injection and routine treatment,and patients (180 cases) in control group could be treated with other drugs for activating blood circulation to dissipate blood stasis on the basis of routine treatment.The patients were telephone followed-up visited 3,6,and 12 months after discharge for pharmacodynamic indexes:evaluation of activities of daily living (ADL) score,self-care rate,cure rate,recurrence rate,and all-cause mortality;economic indicators:the patient work recovery rate,cost effectiveness ratio (CER),and the incidence,and severity of adverse events,to assess the differences in the long-term benefits of different treatment regimens.Results Follow-up in 3,6,and 12 months showed that ADL score,cure rate,self-care rate,and work recovery rate of the treatment group were better than those of control group,and the difference was statistically significant.Follow-up in 12 months showed that,recurrence rate and mortality rate in the treatment group was better than that in the control group,with statistical difference.Follow-up in 6 and 12 months showed that CER of treatment group was smaller than that of the control group.The incidence of adverse reactions was low in the two groups.Conclusion Long term evaluation showed that patients treated with Ginkgolide Injection had better clinical outcomes and better CER than those without it,which proved the effectiveness and economic efficacy of Ginkgolide Inj ection in the treatment of stroke.

The expressions of transforming growth factor β1 (TGF-β1), fibronectin (FN), and collagen Ⅳ in human mesangial cells were augmented with increased concentrations of glucose.Pigment epithelium-derived factor (PEDF) at concentrations of 40-160 nmol/L significantly inhibited TGF-β1 expression in a dose-dependent manner(P＜0.01).PEDF at concentrations of 5-40 nmol/L significantly decreased FN and collagen Ⅳ expressions in a dose-dependent manner(P＜0.01) ,suggesting that PEDF may play a salutary role in diabetic nephropathy by its antifibrogenic activity.

To investigate the expression of vascular endothelial growth factor (VEGF)and the levels of reactive oxygen species (ROS)in human mesangial cells cultured in high glucose and being intervened by pigment epithelium-derived factor (PEDF). The results showed that with increased glucose concentration, the expressions of VEGF and ROS generation also gradually increased and PEDF significantly downregulated VEGF expression and ROS generation in a dose-dependent manner. PEDF may delay the diabetic nephropathy progress by improving vascular permeability and inhibiting oxidative stress.

Objective To evaluate short-term curative effect of chloroquine combined with traditional Chinese medicine in treatment of erosion lichen planus. Methods 40 cases were chosen and randomly divided into two groups. The treatment group included 20 cases were treated with chloroquine combined with traditional Chinese medicine. The control group with 20 cases was treated only with chloroquine. The curative effect of the two groups were compared. Results Comparing the two groups, in the treatment group, the pain was remarkably relieved and the erosion areas were obviously smaller. Significant changes were observed statisticly. The overall effectiveness of the treatment group was 85% ,but that of the control group was 65%. Conclusion The treatment of chloroquine combined with traditional Chinese medicine have a short-term clinical effect on erosion lichen planus.

Objective To evaluate the rat model of dry eye induced by topical administration of benzalkonium chloride and compare the morphological characteristics of corneal and conjunctival tissues of the normal and model rats . Methods Topical administration of benzalkonium chloride (0.3%) twice per day for seven days to induce the rat model of dry eye.Pathology with HE and periodic acid-Schiff staining and transmission electron microscopy were performed to evaluate the corneal and conjunctival changes .Results The corneal and conjunctival epithelial cells were sloughed off , the number of goblet cells was decreased in the dry eye model .Microvilli were obviously lost in the surface epithelial cells of the dry eye rat cornea and conjunctiva compared with the normal rats , as indicated by the amount and size of microvilli . Conclusions The changes in the corneal and conjunctival epithelia of BAC-induced rat dry eye are similar to the changes in human dry eye .This rat model may play an essential role for dry eye studies in the future .

Perinatal glucocorticoid therapy has been proved to be effective on promoting fetal/neonatal lung maturity and has contributed to a dramatic improvement in the mortality and morbidity associated with neonatal respiratory distress syndrome.The underlying mechanisms studies are aimed primarily at accelerating the development of alveoli and pulmonary surfactant system.Meanwhile,a growing number of investigations focus on the side effects of perinatal glucocorticoid therapy on fetal/neonatal.Whether the repeat antenatal glucocorticoid and early postnatal glucocorticoid by intravenous injection is safe remains unclear.More studies are needed on the different route of giving glucocorticoid,the effect of different doses and their machanisms.This review presents the relevant information surrounding perinatal glucocorticoid therapy to enhance fetal/neonatal lung maturity,including clinical and animal studies over the last decades.

Interleukin 24(IL 24),also called the melanoma differentiation associated gene 7(MDA 7),is stably expressed in human tissues associated with the immune system such as the spleen,thymus,peripheral blood leukocytes and normal melanocytes. IL 24 binds to IL 20 and IL 22 receptor complexes(IL 22R1/IL 20R2 and IL 20R1/IL 20R2),and induces secretion of high levels of IL 6,TNF alpha,and IFN gamma and low levels of IL 1beta,IL 12,and GM CSF from human PBMC. Adenoviral IL 24(Ad IL 24) induces growth suppression and apoptosis selectively in diverse human cancers and tumor cell lines without producing any apparent harmful effect in normal cells. The effects of Ad IL 24 are associated to the ratio of pro apoptotic(BAX,BAK) to anti apoptotic(Bcl 2) proteins,and the up regulation of p38 MAPK and a family of growth arrest and DNA damage(GADD) inducible genes. These demonstrate the potential therapeutic effects of Ad IL 24 in human cancer.

Objective To discuss the clinical and pathological features of herniation secondary to cerebral infarction. Method Clinical and pathologic characteristics of 50 cases died of herniation due to cerebral infarction were analysised. Results The clinical manifestations,such as consciousness disturbance,pupillary change,hemiplegia or tetraplegia were detected in all 50 cases,the average time from onset to herniation was (3.36?1.12)d,the time herniation to death was 20 h～7 d,average about (1.5?0.98)d. The large size cerebral infarctions caused by internal carotid artery,middle cerebral artery and/or vertebral artery occlusion were pathologically confirmed.hemorrhagic cerebral infarctions caused by cerebral embolism were found in 25 cases and the ischenmic infarctions caused by cerebral thrombosis in 25 caese.Site of infarction were cerebral hemisphere (31 cases), brain stem (15 cases), supratentorial and infratentorial brain (4 cases).Of the 50 cases,36 cases had hippocampal gyrus herniation,36 cases with cerebellur throat-almond herniation,18 cases with central herniation,17 cases with cingulated gyrus herniation,and 27 cases with sphenoidal crest herniation. Usually there were several herniation existing in the same patient. Among 50 cases,11cases had two kinds of herniation,10 cases with three kinds of herniation,9 cases with four kind of herniation, and 5 cases with five kinds of herniation.Conclusions Herniation secondary to cerebral infarction were mainly presented in the large size cerebral infarction caused by internal carotid artery or middle cerebral artery occlusion.the time of herniation was in early stage of disease.Most of patients were hippocampal gyrus herniation and cerebellur throat-almond herniation.Usually there were several herniation existing in the same patient.

Objective To discuss the clinical characteristics and pathological changes of basilar artery aneurysm.Methods The clinical materials and brain topography results were analyzed retrospectively in 4 patients with basilar artery aneurysm.Results The onsets of disease in all cases were acute and common manifestations were coma,positive meningeal irritation sign and ocular dyskinesis.3 cases showed hypertention,2 cases presented with hemiparalysis,all cases died of herniation.3 cases of basilar artery trunk fusiform aneurysm and 1 case of basilar artery furcation saccular aneurysm were detected in autopsy.There were aneurysm rupture,subarachnoid hemorrhage and swell,necrosis,softening,gliosis of brain tissue confirmed pathologically in all cases.Conclusion Hypertension is probably the most important cause of aneurysm rupture.Signs and symptoms of subarachnoid are the most common manifestation when basilar artery aneurysm ruptures with poor prognosis.Herniation is the main cause of death.

Objective To explore the influence of IFN-? on anti-proliferation and apoptosis of the Caspase-8 silenced neuroblastoma cell line induced by doxorubicin and the influence mechanism.Methods MTT and flow cytometric analysis were used to detect the survival and apoptosis rates before and after the combined treatment of IFN-? and doxorubicin.Immunohistochemical staining was used to detect the expression of caspase-8 protein before and after the treatment of IFN-?.Results The survival rates of doxorubicin(0.03,0.10,0.30?g/ml)used alone for 24h were(95.62?13.03)%,(82.62?7.94)%,(64.84?9.19)%,IFN-?(10,100,1000U/ml)used alone for 48h were(98.37%?11.25)%,(97.15?5.36)%,(98.84?7.41)%.The survival rates of IFN-?(1000U/ml)combined with different concentration of doxorubicin(0.03,0.10,0.30?g/ml)were significantly lower than that of doxorubicin(0.03,0.10,0.30?g/ml)alone.The apoptosis rate of doxorubicin(0.30?g/ml)alone was(22.00?6.55)%,IFN-?(1000U/ml)alone was (8.22?4.00)%,whereas the apoptosis rate of the combined treatment of IFN-? and doxorubicin wassignificantly higher than that of doxorubicin alone;Immunohistochemical staining showed that caspase-8 protein was negative in SH-SY5Y cell line,whereas it become positiveafter the treatment of IFN-?(1000U/ml)for 48h.Conclusion Treating human neuroblastoma cell line SH-SY5Y cell with doxorubicin may induce anti-proliferation and apoptosis.Combined treatment with IFN-? may significantly increase this effect.The mechanism may be realized by upregulating the expression of caspase-8 protein.
