Chinese Journal of Biologicals 2024;37(2):183-187
Objective To investigate the effect of glutaminase 1(GLS1)specific inhibitor BPTES[bis-2-(5-phenylacetamido-1,3,4-thiadiazol-2-yl)ethyl sulfide]on the liver fibrosis in the mouse model of liver fibrosis induced by carbon tetrachloride(CCl4).Methods Male C57BL/6J mice were intraperitoneally injected with olive oil(control group),10%CCl4(10 μL/g,model group)or 10% CCl4(10 μL/g)+ BPTES(10 mg/kg,treatment group),with 10 mice in each group,two doses a week for four weeks to establish liver fibrosis model. Collagen deposition in mouse liver tissue was observed by Sirius red staining. The expression levels of actin alpha 2(Acta2),collagen typeⅠalpha 1(Col1a1)GLS1 and GLS1 protein were detected by qRT-PCR and immunohistochemical staining.Results Compared with the control group,the liver tissue of mice in the model group was generally enlarged,the surface was not smooth and granular,and the ratio of liver mass to tibia length significantly increased(t = 2. 979,P < 0. 05);The Sirius red positive area of collagen deposition increased signifi-cantly in the liver tissue of mice in the model group(t = 7. 661,P < 0. 01),the relative expression levels of Acta2 and Col1a1 significantly increased(t = 4. 335 and 5. 319,respectively,each P < 0. 01),and the mRNA and protein levels of GLS1 significantly increased(t = 5. 319 and 9. 725,respectively,each P < 0. 01). However,compared with the model group,the BPTES treatment group had a reduction in liver mass,a significant reduction in the Sirius red positive area of collagen deposition in liver tissue(t = 7. 427,P < 0. 01),and a significant reduction in the relative expressions of Atca2 and Col1a1(t = 3. 713 and 2. 628,respectively,each P < 0. 05).Conclusion Inhibition of GLS1activity can significantly improve the degree of liver fibrosis induced by CCl4,providing a new idea for the treatment of liver fibrosis.

7.EFFECTS OF TRH AND INTERLEUKIN-1? ON CYTOSOLIC FREE CALCIUM MOBILIZATION IN RAT GH_3 PITUITARY CULTURED IN VITRO
Chinese Journal of Endocrinology and Metabolism 1985;0(01):-
The effects of TRH and recombinant human IL-1? on cytosolic free calcium mobilization in rat GH, pituitary cells cultured in vitro was studied spectrofluorometrically using Fura-2 as Ga++ indicator. The results showed that TRH 10-7~10-9mol/L stimulated the cytosolic Ca++mobilization in a dose-dependent manner. IL-1 alone in the concentration ranging from 0.01 to 10 U/ml did not increase the intracellular Ca++ level. 1- and 3-minute pretreatment of the GH3 cells with IL-1? 0.1 U/ml significantly inhibited TRH-induced Ca++ mobilization, whereas such suppressive effects were significantly diminished when IL-1/3 and TRH were added at the same time. These findings suggest that Ca++ may signal a TRH effect in pituitary cells and IL-1? influences pituitary function by inhibiting Ca++ mobilization induced by TRH.

Journal of Integrative Medicine 2010;8(12):1190-4
In order to elucidate the mechanisms of Chinese herbal medicine, much work has been done based on chemical constituent-target in the molecular system. It cannot comply with the holistic efficacy of Chinese herbal medicine. Thus, the authors of this paper proposed to study the functional target adopted from Western medicine. The data of Chinese herbal function were collected from 2005 edition of The People's Republic of China Pharmacopoeia. A total of 135 functional targets were found, and a network about functional target and mode of action was built. The authors also explored the applications of functional target and the network combined with Sijunzi Decoction and Mahuang Decoction. The results, reflecting the feature of Chinese herbal medicine, will not only be helpful to elucidate the holistic mechanisms of Chinese herbal medicine, but also beneficial to studying the theory of Chinese formulas and developing new formulas.

Chinese Journal of Physical Medicine and Rehabilitation 2011;33(7):535-539
Objective To evaluate the clinical effect of ultrasound-guided botulinum toxin A (BTX-A)injection for upper limb spasticity in children with cerebral palsy.Methods Twenty children with upper limb spasticity resulting from cerebral palsy were divided equally into a BTX-A injection group and a control group. Both groups received standard rehabilitation treatment. For the injection group, color ultrasonography was used to guide the accurate injection of BTX-A into the spastic muscles of the arm. They received rehabilitation training the day after the injection. For all patients, muscle spasticity and upper limb movement and function were evaluated before treatment and 1, 2, 4, 8 and 12 weeks later using a modified Ashworth scale and the Fugl-Meyer assessment.Results After two weeks of treatment, muscle spasticity and upper limb movement and function in the injection group were significantly better than before the injection.The improvement in muscle spasticity was greatest two weeks after the injection. The average therapeutic effect in the injection group was significantly better than among the controls.Conclusion BTX-A injection under ultrasound guidance helps relieve upper limb spasticity in cerebral palsy. It has the advantages of accurate localization and safety and gives superior results compared to rehabilitation treatment alone.
