Tenecteplase Plus Butyphthalide for Stroke Within 4.5-6 Hours of Onset (EXIT-BT): a Phase 2 Study.

To date, the benefit of intravenous thrombolysis is confined to within 4.5 h of onset for acute ischemic stroke (AIS) without advanced neuroimaging selection. The current trial aimed to investigate the safety and efficacy of intravenous tenecteplase (TNK) plus Dl-3-n-Butylphthalide (NBP) in AIS within 4.

Intravenous Tenecteplase for Acute Ischemic Stroke Within 4.5-24 Hours of Onset (ROSE-TNK): A Phase 2, Randomized, Multicenter Study.

Background And Purpose: Intravenous tenecteplase (TNK) efficacy has not been well demonstrated in acute ischemic stroke (AIS) beyond 4.5 hours after onset. This study aimed to determine the effect of intravenous TNK for AIS within 4.

[Effects of post-traumatic stress disorder on the excitability of glutamatergic and GABAergic neurons in dorsal and ventral hippocampus in mice].

The purpose of this study was to investigate the effects of post-traumatic stress disorder (PTSD) on electrophysiological characteristics of glutamatergic and GABAergic neurons in dorsal hippocampus (dHPC) and ventral hippocampus (vHPC) in mice, and to elucidate the mechanisms underlying the plasticity of hippocampal neurons and memory regulation after PTSD. Male C57Thy1-YFP/GAD67-GFP mice were randomly divided into PTSD group and control group. Unavoidable foot shock (FS) was applied to establish PTSD model.

Effect of Argatroban Plus Intravenous Alteplase vs Intravenous Alteplase Alone on Neurologic Function in Patients With Acute Ischemic Stroke: The ARAIS Randomized Clinical Trial.

Importance: Previous studies suggested a benefit of argatroban plus alteplase (recombinant tissue-type plasminogen activator) in patients with acute ischemic stroke (AIS). However, robust evidence in trials with large sample sizes is lacking.

Objective: To assess the efficacy of argatroban plus alteplase for AIS.

Migration of a Hem-o-Lok clip to the renal pelvis after laparoscopic partial nephrectomy: A case report.

Background: Hem-o-Lok clip (HOLC) has been widely used in laparoscopic surgery due to its ease of application and secure clamping, though the rare complications associated with this technique should not be ignored. The rare complications of laparoscopic partial nephrectomy consist of the clip migrating into the renal pelvis and acting as a nidus for stone formation.

Case Summary: The case described here involved a 63-year-old woman who was found with stones in the right kidney and upper ureter during a recent reexamination following laparoscopic partial nephrectomy.

[Molecular mechanism of geniposide in regulating GLUT2 glycosylation in pancreatic β cells].

Type 2 diabetes mellitus( T2 DM) is a common chronic metabolic disease characterized by persistent hyperglycemia and insulin resistance. In pancreatic β-cells,glucose-stimulated insulin secretion( GSIS) plays a pivotal role in maintaining the balance of blood glucose level. Previous studies have shown that geniposide,one of the active components of Gardenia jasminoides,could quickly regulate the absorption and metabolism of glucose,and affect glucose-stimulated insulin secretion in pancreatic β cells,but the specific mechanism needs to be further explored.

Prostate stromal tumor with prostatic cysts after transurethral resection of the prostate: A case report.

Background: A prostatic stromal tumor is deemed to be a rare oncology condition. Based on the retrospective analysis of clinical data and scientific literature review, a case of prostatic stromal tumor was reported in this article to explore the diagnosis, treatment and prognosis of this rare disease.

Case Summary: The present case involved an older male patient who was admitted to our department for a medical consultation of dysuria.

[Dynamic changes of serum antibody titer in a rabbit model of Acanthamoeba keratitis].

Ten healthy New Zealand white rabbits were randomly divided into two groups named as experiment group (n=8) and normal control group (n=2). Left eyes were for experiment, right eyes served as control. New Zealand rabbits were each injected by subconjunctival route with hydrocortisone for three days, and then Acanthamoeba keratitis was induced by intrastromal injection of live Acanthamoeba healyi trophozoites and cysts.

[Prevention of Inonotus obliquus polysaccharides for high power microwave radiation induced testicular injury in rats: an experimental research].

Objective: To investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.

Methods: A total of 30 male Wistar rats were randomly divided into 5 groups, i.e.

B7-H1 and B7-H4 expression in colorectal carcinoma: correlation with tumor FOXP3(+) regulatory T-cell infiltration.

B7-H1 and B7-H4 are newly discovered members of the B7-CD28 family. They can inhibit T cell activation and proliferation and regulate T cell immune response negatively. Both B7-H1 and B7-H4 are expressed in many tumors and are classified as co-inhibitors of cell-mediated immunity.

Inotodiol inhabits proliferation and induces apoptosis through modulating expression of cyclinE, p27, bcl-2, and bax in human cervical cancer HeLa cells.

Inonotus obliquus is a medicinal mushroom that has been used as an effective agent to treat various diseases such as diabetes, tuberculosis and cancer. Inotodiol, an included triterpenoid shows significant anti-tumor effect. However, the mechanisms have not been well documented.

Validity of inorganic nanosheets as an efficient planar substituent to enhance the enantioselectivity of transition-metal-catalyzed asymmetric synthesis.

Effectively enhancing the enantioselectivity is a persistent challenge in heterogeneous asymmetric catalysis. Here, the validity of a layered double hydroxides (LDH) nanosheet as an efficient planar substituent to enhance the enantioselectivity has been investigated theoretically; first in vanadium-catalyzed asymmetric epoxidation of allylic alcohols, and then in zinc-catalyzed direct asymmetric aldol addition. The computational predication is further confirmed experimentally in zinc-catalyzed direct asymmetric aldol addition by controlling the location of catalytic sites.

Nanosheet-enhanced asymmetric induction of chiral α-amino acids in catalytic aldol reaction.

An efficient ligand design strategy towards boosting asymmetric induction was proposed, which simply employed inorganic nanosheets to modify α-amino acids and has been demonstrated to be effective in vanadium-catalyzed epoxidation of allylic alcohols. Here, the strategy was first extended to zinc-catalyzed asymmetric aldol reaction, a versatile bottom-up route to make complex functional compounds. Zinc, the second-most abundant transition metal in humans, is an environment-friendly catalytic center.

Nanosheet-enhanced enantioselectivity in the vanadium-catalyzed asymmetric epoxidation of allylic alcohols.

The use of suitable chiral ligands is an efficient means of producing highly enantioselective transition-metal catalysts. Herein, we report a facile, economic, and effective strategy for the design of chiral ligands that demonstrate enhanced enantioselectivity and catalytic efficacy. Our simple strategy employs naturally occurring or synthetic inorganic nanosheets as huge and rigid planar substituents for, but not limited to, naturally available α-amino-acid ligands; these ligands were successfully used in the vanadium-catalyzed asymmetric epoxidation of allylic alcohols.

[Preliminary study on using acousto-optic tunable filter as wavelength selector for atomic absorption spectrometry].

An acousto-optic tunable filter (AOTF) is an all-solid-state, electronic monochromator that is based on the diffraction of light by an acoustic wave in an anisotropic crystal. It is a new kind of tunable small filter with narrow band compared with traditional unicolor filter. The filter can diffract incident white light at a specific wavelength when a specific radio frequency is applied into it.
