Chinese Journal of Pathophysiology 2018;34(1):87-93
AIM:To investigate the effect of SH2 domain-containing inositol 5-phosphatase 1(SHIP1)on the viability and apoptosis of leukemia cells by regulating signal transducer and activator of transcription 3(STAT3)signaling pathway.METHODS:Human leukemia Jurkat cells were transfected with null vector and SHIP1 overexpression vector in negative control(NC)group and SHIP1 group,respectively.The cells without treatment served as control group.The transfection efficiency was detected by real-time PCR and Western blot.The changes of the cell activity were measured by MTT assay.The apoptosis was detected by flow cytometry.The protein levels of cleaved caspase-3,STAT3 and p-STAT3 were determined by Western blot.The STAT3 signaling pathway inhibitor AG 490 was applied to the cells in control group and SHIP1 group as control +AG490 group and SHIP1+AG490 group,respectively,and the above indexes were also ana-lyzed.RESULTS:Compared with the control group and NC group ,the mRNA and protein expression levels of SHIP 1 in SHIP1 group were both upregulated ,the cell viability was increased ,the apoptotic rate was decreased ,the protein level of cleaved caspase-3 was upregulated ,and the protein level of p-STAT3 was decreased(P<0.05 ).Compared with control group and control +AG490 group,the cell viability in SHIP1+AG490 group was decreased ,the protein level of cleaved caspase-3 was increased the protein level of p-STAT3 was decreased ,and the apoptotic rate was increased(P<0.05 ). CONCLUSION:SHIP1 inhibits the viability and promotes the apoptosis of human leukemia Jurkat cells by inhibiting the STAT3 signaling pathway.

Objective To identify related factors for hypoglycemic episodes in patients with type 2 diabetes mellitus(T2DM)through continuous glucose monitoring(CGM). Methods The included 147 patients with T2DM were those who had undergone CGM for 5 days in our ward of Department of Endocrinology and Metabolism,Huashan Hospital from Dec 2018 to Oct 2019. The general information, laboratory parameters and CGM parameters of the patients were collected. According to whether there wasan episode of hypoglycemia during the monitoring period,the patients were divided into non-hypoglycemia group and hypoglycemic group. A single hypoglycemia episode was defined as a sensor monitoring blood glucose of less than 3.9 mmol/L and lasting for more than 15 minutes.CGM parameters included the mean blood glucose(MBG),standard deviation(SD),coefficient of variation(CV),the differences between maximum and minimum blood glucose (BG) levels (ΔBG),mean amplitude of glycemic excursions (MAGE)and the percentage of time in range(%TIR)of BG at <3.9 mmol/L,3.9-7.8 mmol/L,>7.8 mmol/L,3.9-10.0 mmol/L,and >10.0 mmol/L. Results Logistic regression analysis showed that lower estimated glomerular filtration rate(eGFR)levels,increased use of insulin and its analogs and lower MBG levels were associated with hypoglycemic episodes. Spearman correlation analysis showed that the MBG level and the %TIR of BG>7.8 mmol/L and BG>10.0 mmol/L were negatively associated while glycemic variability(GV)levels(SD,CV,ΔBG,MAGE)and % TIR of BG at 3.9-7.8 mmol/L were positively associated with hypoglycemic episodes. Pearson correlation analysis showed that the duration of hypoglycemic episodes was positively correlated with the use of sulfonylureas and CV levels. Conclusion Lower eGFR levels,increased treatment with insulin and its analogs and lower MBG levels were related factors for hypoglycemic episodes in patients with T2DM.

OBJECTIVETo observe the effect of curcumin on nitric oxide (NO) in plasma of atherosclerotic rabbits, activity of constitutive nitric oxide synthase (cNOS) and asymmetric dimethylarginine (ADMA), and discuss curcumin's effect against AS and its correlation with ADMA.
METHODThirty-eight male Japanese white rabbits were randomly divided into four groups: the control group (eight rabbits fed with standard diets), the model group (ten rabbits fed with high-fat diets), the low dose curcumin group (ten rabbits fed with high-fat diets and 100 mg . kg-1 d -1 ) and the high dose curcumin group (ten rabbits fed with high-fat diets and 200 mg kg-1 d-1 curcumin). At the end of the 12th week, their plasmas were tested for TC, LDL-C, NO, endothelin (ET) , ADMA and activity of aortic cNOS. Aortic tissues were collected for histological examinations.
RESULTThe three groups fed with high-fat diets showed higher plasma ADMA and ET than the control group (P <0. 01) , but with decrease in plasma NO concentration and arterial cNOS activity (P <0. 01). Compared with the model group (P <0. 05) , the curcumin groups showed lower plasma ADMA and ET (P <0. 05), but higher plasma NO concentration and arterial cNOS activity than the model group (P <0. 01). There was no significant difference between the two curcumin groups.
CONCLUSIONCurcumin may play an important protective role in AS process by reducing plasma ADMA level. [Key words] atherosclerosis; asymmetric dimethylarginine; crucumin; nitric oxide; nitric oxide synthase

In recent years, the traditional Chinese medicine(TCM)industry has experienced rapid development, resulting in a significant amount of Chinese medicinal residues generated during the industrial manufacturing process. Currently, the main methods of handling Chinese medicinal residues include stacking, landfilling, and incineration, which lead to substantial resource waste and potential environmental pollution. With "carbon peak" and "carbon neutrality"( "Dual Carbon")becoming national strategic goals, the TCM industry is ushering in a new wave of "low-carbon" trends, and the high-value utilization of Chinese medicinal residues has become a breakthrough for implementing a low-carbon economy in the TCM sector. From the perspective of a low-carbon economy, this article reviewed literature in China and abroad to summarize the microbial transformation technology, enzymatic conversion technology, biomass pyrolysis, gasification, hydrothermal liquefaction, and other high-value utilization technologies for Chinese medicinal residues. It also overviewed the applications of Chinese medicinal residue in feed additives, organic fertilizers, edible mushroom cultivation substrates, preparation of activated carbon for wastewater treatment, and new energy batteries. Considering the current status of resource utilization of Chinese medicinal residues, feasible strategies and suggestions for resource development and utilization were proposed to improve the quality and efficiency of the Chinese medicinal resource industry chain and promote green development, thereby providing research ideas and theoretical basis for achieving carbon peak and carbon neutrality goals.
