Objective:To analyze the relationship between aquaporin 1 (AQP1) level and vascular calcification in patients with diabetes nephropathy.Methods:A total of 125 diabetic nephropathy patients admitted to Suzhou Hospital of Nanjing Medical University from March 2020 to March 2023 were retrospectively selected as case group. The case group was divided into group A (diabetes nephropathy stage Ⅰ and Ⅱ) with 31 cases, group B (diabetes nephropathy stage Ⅲ) with 32 cases, group C (diabetes nephropathy stage Ⅳ) with 39 cases, and group D (diabetes nephropathy stage V) with 23 cases. In these patients, 51 cases had vascular calcification, taken as the calcification group, and 74 cases had no vascular calcification, taken as the non calcification group. Sixty volunteers who underwent health examinations in the same hospital were selected as the control group. Receiver operating characteristic curve was used to analyze the predictive value of AQP1 on vascular calcification in diabetes nephropathy patients and to explore the related factors of vascular calcification in diabetes nephropathy patients.Results:Compared with the control group, AQP1 level and calcification rate in groups A, B, C and D were higher: 6.41 ± 1.04, 7.93 ± 1.23, 9.50 ± 1.52 and 11.37 ± 2.01 vs. 3.83 ± 0.56 ng/L, 6.45% (2/31), 28.13% (9/32), 51.28% (20/29) and 86.96% (20/23) vs. 0 ( P<0.05). Compared with group A, the level of AQP1 and calcification rate in groups B, C and D were higher ( P<0.05); compared with group B, the AQP1 level and calcification rate in groups C and D were higher ( P<0.05); compared with group C, the level of AQP1 and calcification rate in group D were higher ( P<0.05). Compared to the non calcification group, the levels of uric acid, homocysteine and cystatin C in calcification group were higher: (313.82 ± 38.72) μmol/L vs. (253.42 ± 30.14) μmol/L, (20.03 ± 3.01) μmol/L vs. (15.01 ± 2.71) μmol/L, (1.73 ± 0.26) mg/L vs. (1.30 ± 0.17) mg/L ( P<0.05). AQP1 was positively correlated with uric acid, homocysteine, and cystatin C ( P<0.05). The area under the curve of AQP1, uric acid, homocysteine and cystatin C in predicting vascular calcification in patients with diabetes nephropathy were 0.892, 0.803, 0.738 and 0.763, respectively. Taking whether vascular calcification occurs in patients with diabetes nephropathy as the dependent variable (no = 0, yes = 1), the variables of P<0.05 in the single factor analysis were selected for multivariate Logistic regression analysis. The results showed that uric acid, homocysteine, cystatin C and AQP1 were the main factors affecting vascular calcification in patients with diabetes nephropathy ( P<0.05). Conclusions:Serum AQP1 has a high predictive value for vascular calcification in diabetes nephropathy patients, and is expected to be used as a biomarker for early diagnosis of vascular calcification in diabetes nephropathy patients.

OBJECTIVE:
To evaluate the value of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) for assessing disease activity in patients with rheumatoid arthritis (RA) treated with tofacitinib.
METHODS:
This retrospective study was conducted among 98 RA patients in active stage treated with tofacitinib in Third Xiangya Hospital and 100 healthy control subjects from the Health Management Center of the hospital from 2019 to 2021. We collected blood samples from all the participants for measurement of erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and other blood parameters 1 month before and 6 months after tofacitinib treatment. We further evaluated PLR and NLR before and after tofacitinib treatment in the RA patients, and analyzed their correlations with RA disease activity.
RESULTS:
PLR and NLR increased significantly in RA patients as compared with the healthy controls. In the RA patients, PLR and NLR were positively correlated with the levels of hs- CRP, ESR, IL- 6, Disease Activity Score of 28 joints-ESR (DAS28-ESR), anti-cyclic citrullinated peptide (CCP), and rheumatoid factor (RF) before and after tofacitinib treatment. Tofacitinib treatment for 6 months significantly decreased hs-CRP, ESR, IL-6, CCP, RF and DAS28-ESR levels in the RA patients.
CONCLUSION
NLR and PLR can be useful biomarkers for assessing disease activity in RA patients treated with tofacitinib.

Objective:To investigate the c-Jun N-terminal kinase (JNK), CCAAT/enhancer-binding protein homologous protein (CHOP) pathway apoptosis and the changes of cytokine levels in immune-related organs and tissues of sepsis mice at different time points.Methods:Twenty-seven male BALB/c mice were divided into normal group, sepsis 6 hours group and sepsis 12 hours group by the block randomization method, with 9 mice in each group. The sepsis model was made by cecal ligation and puncture (CLP). Blood sample was collected from each group at the corresponding time point, and the serum levels of tumor necrosis factor-α (TNF-α), interleukin (IL-1β, IL-10) were measured by enzyme linked immunosorbent assay (ELISA). The spleen, thymus and appendix tissues were taken from the mice to detect the expressions of phosphorylation-JNK (p-JNK), JNK1, CHOP and cleaved caspase-3 protein by Western Blot.Results:The level of cytokines, p-JNK/JNK1 ratio, CHOP and caspase-3 in spleen tissues, and the CHOP, caspase-3 in thymus and appendix tissue in the sepsis 6 hours group were significantly higher than those in the normal group [serum TNF-α (ng/L): 24.29±3.09 vs. 2.93±2.09, serum IL-1β (ng/L): 5.00±3.19 vs. 3.54±1.53, serum IL-10 (ng/L): 1 963.93±270.20 vs. 275.09±45.21, spleen p-JNK/JNK1 ratio: 0.257±0.126 vs. 0.154±0.068, spleen CHOP/β-actin: 0.201±0.131 vs. 0.142±0.068, spleen caspase-3/β-actin: 0.215±0.126 vs. 0.098±0.088, thymus CHOP/β-actin: 0.122±0.071 vs. 0.089±0.067, thymus caspase-3/β-actin: 0.258±0.145 vs. 0.108±0.045, appendix CHOP/β-actin: 0.361±0.134 vs. 0.215±0.112, appendix caspase-3/β-actin: 0.439±0.211 vs. 0.321±0.145, all P < 0.05]. However, there were no significant difference in the p-JNK/JNK1 ratio in thymus and appendix (thymus p-JNK/JNK1 ratio: 1.221±0.776 vs. 1.168±0.475, appendix p-JNK/JNK1 ratio: 2.014±1.227 vs. 1.828±0.915, both P > 0.05). Cytokine levels and the p-JNK/JNK1 ratio, CHOP, caspase-3 in spleen, thymus, and appendix in the sepsis 12 hours group were further increased when compared with those in the sepsis 6 hours group, except for a significant decrease in IL-10 level [serum IL-10 (ng/L): 1 698.98±210.52 vs. 1 963.93±270.20, serum TNF-α (ng/L): 41.66±6.57 vs. 24.29±3.09, serum IL-1β (ng/L): 10.37±4.14 vs. 5.00±3.19, spleen p-JNK/JNK1 ratio: 0.399±0.135 vs. 0.257±0.126, spleen CHOP/β-actin: 0.298±0.145 vs. 0.201±0.131, spleen caspase-3/β-actin: 0.353±0.145 vs. 0.215±0.126, thymus p-JNK/JNK1 ratio: 1.667±0.891 vs. 1.221±0.776, thymus CHOP/β-actin: 0.207±0.133 vs. 0.122±0.071, thymus caspase-3/β-actin: 0.416±0.179 vs. 0.258±0.145, appendix p-JNK/JNK1 ratio: 2.425±1.361 vs. 2.014±1.227, appendix CHOP/β-actin: 0.456±0.189 vs. 0.361±0.134, appendix caspase-3/β-actin: 0.635±0.289 vs. 0.439±0.211, all P < 0.05]. Conclusions:The endoplasmic reticulum pathway JNK and CHOP pathways are involved in immune-related cell apoptosis and cytokine expression in mice with sepsis. Apoptosis is more obvious at 12 hours than at 6 hours, and the inflammatory response is stronger.

OBJECTIVE To explore the effect of aqueous extract of Zheng Chaihu Yin(ZCH)on paracetamol(acetaminophen,APAP)-induced hepatotoxicity. METHODS Male ICR mice were divided into three scenarios randomly:the single treatment dose of ZCH,multiple treatment or pretreatment dose of ZCH. Each scenario had a up control group and an APAP model group,while single treatment dose of ZCH group had a ZCH group at the same time. The dose of APAP and ZCH was 500 mg·kg-1 and 36 g · kg- 1,respectively. 24 h after the last administration,plasma and liver samples were prepared. Ultra- performance liquid chromatography/quadrupole- time- of- flight mass spectrometry (UPLC-Q-TOF-MS)based metabolomics profiling was used to examine changes in plasma after expo?sure to ZCH,APAP or co-exposure to ZCH and APAP. Glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminas (GOT) values were determined by a biochemical auto analyzer in plasma. Histopathologic changes in the liver were observed and the area was calculated after HE staining. The data were analyzed with SPSS16.0 statistical software and the results were compared with the test between the two groups to find biomarkers. Also,SIMCA software was used for partial least squares-discriminant analysis (PLS-DA) pattern recognition. RESULTS Compared to control group, APAP dosing alone caused an increase in plasma transaminases and alterations in multiple metabolic pathways. Compared to APAP group,decrease in plasma transaminases was noted when ZCH was administered after or prior to APAP. Histopathologic results showed that in the single treatment group, multiple treatment group and pretreatment group,ZCH could alleviate the liver damage induced by APAP from (32.3 ± 12.0)% to (14.2 ± 9.9)%,(8.6 ± 7.9)% to (5.2 ± 1.7)% and (32.5 ± 10.0)% to (5.2 ± 6.4)%(P<0.05). Similarly,the PLS-DA of the LC-MS data showed that the groups dosed with APAP alone were the most distinct from controls,while animals dosed with ZCH prior to or after APAP treatment were located near control group. Metabolic spectrum results showed that ZCH could restore the changes in endogenous substances including lipid metabolism,amino acid metabolism,sugar metabolism and energy metabolism induced by APAP to normal. CONCLUSION ZCH water-extraction plays major roles in the regulation of metabolism on APAP-induced liver injury. These studies demonstrate that UPLC-Q-TOF-MS-based metabolomic analysis can be sensitively and accurately predict the initiation and progres?sion of liver injury and greatly contribute to a better understanding of the hepatoprotective effects of ZCH in a clinical environment.

Aim To investigate the effect of Rhein on the movement and invasiveness of human ovarian carci-noma cells with directional high lymphatic metastasis SKOV3-PM4 cells and explore the role of Rac1/LIMK1/cofilin signaling pathway. Methods Migration assay and invasion assay were used to observe the effect of Rhein on the metastatic and invasive ability of SK-OV3-PM4 cells in vitro. The effect of Rhein on the morphology and cytoskeleton ultrastructure of ovarian cancer cells was observed by laser scanning confocal microscope and scanning electron microscope. The protein expression level of Rac1,LIMK1,PAK1 and co-filin were detected by Western blot, respectively. Re-sults Rhein inhibited the abilities of cell invasion and migration of SKOV3-PM4 cells,and the inhibitory rate increased along with the increase of the concentration and treatment duration. After treated with 8. 80 μmol· L-1 ,17. 60 μmol · L-1 , 26. 40 μmol · L-1 of Rhein for 24 h,the abilities of migration and invasion of SK-OV3-PM4 cells were inhibited ( P <0. 05 ); the mor-phology and cytoskeleton ultrastructure of SKOV3-PM4 cells were changed, cellular pseudopod reduced, cell microfilament fractured and its distribution disordered, plasma membrane was uneven and cell gap widened . After treatment of Rhein and Rac1 inhibitor , Rac1 protein expression and the expression of P-LIMK1 , P-PAK1 and P-cofilin notably decreased in a dose-de-pendent manner compared with the control group ( P<0. 05 ) . After Rhein and Rhein plus Rac1 inhibitor treatment ,P-LIMK1, P-cofilin, P-PAK1 protein levels of SKOV3-PM4 cells significantly decreased compared with the control group , and the group of Rac1 inhibi-tor plus Rhein treatment, the phosphorylated protein decreased more significantly ( P <0. 05 ) . After Rac1 activator plus Rhein treatment, phosphorylated protein expression of P-LIMK1 ,P-PAK1 and P-cofilin upregu-lated significantly ( P <0. 05 ) . Conclusions Rhein may be a potential inhibitor of Rac1 and can inhibit the migrating and invasive capabilities of directional high lymphatic metastasis SKOV3-PM4 cells through down-regulating the phosphorylation of Rac1/LIMK1 /cofilin pathway associated protein.

The stereoselective hydrolysis of esmolol in whole blood and in its separated components from rat,rabbit and human was investigated.Blood esterase activities were variable in different species in the order of rat > rabbit > human.Rat plasma showed the high esterase activity and had no stereoselectivity to enantiomers.Rabbit red blood cell (RBC) membrane,RBC cytosol and plasma all hydrolyzed esmolol but with different esterase activity,whereas the hydrolysis in RBC membrane and cytosol showed significant stereoselectivity towards R-(+)-esmolol.Esterase in RBC cytosol from human blood mainly contributed to the esmolol hydrolysis,which was demonstrated with no stereoselctivity.Esterase in human plasma showed a low activity,but a remarkable stereoselectivity with R-(+)-esmolol.In addition,the protein concentration affected the hydrolysis behavior of esmolol in RBC suspension.Protein binding of esmolol enantiomers in human plasma,human serum albumin (HSA) and α1-acid glycoprotein (AGP) revealed that there was a significant difference in bound fractions between two enantiomers,especially for AGP.Our results indicated that the stereoselective protein binding might play a role in the different hydrolysis rates of esmolol enantiomers in human plasma.
