Case report: CD7-targeted autologous CAR-T therapy for the treatment of T-cell acute lymphoblastic leukemia undergoing allogeneic peripheral blood stem cell transplantation in the long-term follow-up.

Introduction: Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a promising approach for treating relapsed/refractory (r/r) T-cell acute lymphoblastic leukemia (T-ALL). However, it is mostly used as a bridging therapy for allogeneic hematopoietic stem cell transplantation (allo-HSCT). Furthermore, secondary allo-HSCT is costly and associated with significantly high treatment-related mortality rate than the primary transplants.

Flip-over of blood vessel intima caused by vascular closure device: A case report.

Background: Complications of vascular closure devices mainly include bleeding, vascular injury, and trapped device that cannot be removed percutaneously. However, arterial stenosis or occlusion induced by vascular injury is rare. This article introduces a rare case with severe acute limb ischemia after using the vascular closure device (StarClose).

[Effects of stand structure regulation on soil labile organic carbon in Pinus elliottii plantation].

Taking 21-year-old Pinus elliottii pure plantation as the control, effects of enrichment planting with broadleaf trees (Liquidambar fornosana) after thinning the conifer trees (P. elliottii) on soil labile organic carbon of different plantations, including 3-year-old, 6-year-old, 9-year-old P. elliottii and 21-year-old P.

Immobilization of cross-linked phenylalanine ammonia lyase aggregates in microporous silica gel.

A separable and highly-stable enzyme system was developed by adsorption of phenylalanine ammonia lyase (PAL) from Rhodotorula glutinis in amino-functionalized macroporous silica gel and subsequent enzyme crosslinking. This resulted in the formation of cross-linked enzyme aggregates (PAL-CLEAs) into macroporous silica gel (MSG-CLEAs). The effect of adsorptive conditions, type of aggregating agent, its concentration as well as that of cross-linking agent was studied.

A simple technique of preparing stable CLEAs of phenylalanine ammonia lyase using co-aggregation with starch and bovine serum albumin.

Cross-linked enzyme aggregates (CLEAs) have been recently proposed as an alternative to conventional immobilization methods on solid carriers. However, the low cross-linking efficiency causes the major activity loss and instability in the conventional protocol for CLEA preparation. Herein, the effects of bovine serum albumin and starch addition on the cross-linking efficiency of CLEAs of phenylalanine ammonia lyase (PAL) from Rhodotorula glutinis were evaluated.

[Eeffects of Coptis Chinensis on vasoconstrictive activity of isolated thoracic aorta of normoxic and chronic intermittent hypobaric hypoxic rats].

Objective: To observe the effects of Coptis Chinensis on vasoconstrictive activity of isolated thoracic aorta rings of normoxic and chronic intermittent hypobaric hypoxic (CIHH) rats, and to investigate the underlying mechanisms.

Methods: Young male Sprague-Dawley rats were randomly divided into normoxic group and CIHH group: the fonnrmer were not given any special treatment; the latter were exposed to hypoxia in a hypobaric chamber simulating 5000 m altitude (PB = 404 mmHg, PO2 = 84 mmHg, 11.1% O2), 6 hours daily for 28 days.
