The liver plays an important regulatory role in maintaining the dynamic balance of coagulation and anticoagulation in the body. Such dynamic balance is fragile in patients with liver cirrhosis， and the risk of bleeding can be increased due to reductions in coagulation factors and platelet count and excessive fibrinolysis； meanwhile， thrombus can be formed due to the increases in von Willebrand factor and coagulation factor Ⅷ， the reductions in anticoagulant protein C and anticoagulant protein S， the increase in thrombin-generating potential， and alterations in antifibrinolytic components. This article reviews the mechanisms of coagulation disorder in liver cirrhosis， so as to help clinicians with the prevention and treatment of bleeding or thrombotic disorders in patients with liver cirrhosis.

Objective To investigate the effects of sulforaphane(SFN)in regulating the macrophage glycolysis via the arachidonate 5-lipoxygenase(ALOX5)/nuclear factor kappa B(NF-κB)signaling pathway on the progression of diabetic nephropathy(DN).Methods Bioinformatics analysis was used to identify the target genes of SFN in the treatment of DN.Human proximal tubular epithelial cell line(HK-2 cells)was induced with 30 mmol/L high glucose(HG)to create an in vitro model of DN.HK-2 cells were divided into the following groups:normal glucose(NG)group,HG group,HG+SFN(3 mmol/L)group,HG+ALOX5 group,HG+SFN(3 mmol/L)+ALOX5 group,HG-treated macrophages+HK-2 group,HG+SFN(3 mmol/L)treated macrophages s+HK-2 group,HG+ALOX5 transfection treated macrophages+HK-2 group,HG+SFN(3 mmol/L)+ALOX5 transfection treated macrophages+HK-2 group.CCK-8 assay was used to detect cell viability,Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL)method was used to detect cell apoptosis;glucose and lactate levels in the cells were measured using assay kits;Western blot was performed to detect the expression of ALOX5,NF-κB,and glycolysis-related proteins hexokinase-2(HK2),pyruvate kinase M2(PKM2),glucose transporter 1(GLUT1)in each group.Diabetic nephropathy(DN)mouse models were established using streptozotocin(STZ)and treated with SFN(0.5 mg/kg).Various biochemical parameters were measured in the mice,and kidney tissue pathology was examined using H&E staining.Western blot was used to detect the expression of glycolysis-related proteins(HK2,PKM2,GLUT1)in kidney macrophages.Results Bioinformatics analysis revealed ALOX5 as the target gene of SFN in treating DN.Compared to the HG group,SFN treatment enhanced HK-2 cell viability and in-hibited apoptosis(P<0.05);concurrently,SFN treatment suppressed HG-induced macrophage glycolysis-related protein and attenuated macrophage-mediated HK-2 cellular injury(P<0.05).Western blot results showed that SFN inhibited the expression of ALOX5 and NF-κB(P<0.05).The mouse experiment results showed that SFN treatment improved kidney function and pathological changes in the kidney of DN mice,and inhibited the related protein expression of acrophage glycolysis in kidney tissue(P<0.05).Conclusion SFN improves the progression of DN by inhibiting the expression of macrophage glycolysis-related protein through the ALOX5/NF-κB signaling pathway.

OBJECTIVE To investigate the anti-inflammatory effects and mechanism of Zhuang medicine Tongfeng li’an capsules on gouty arthritis in combination with in vivo and in vitro experiments. METHODS Sixty rats were randomly divided into normal group， model group， positive control group （27 mg/kg allopurinol+0.27 mg/kg colchicine）， Tongfeng li’an capsules low- dose， medium-dose and high-dose groups （2.2， 4.5， 9.0 g/kg）， with 10 rats in each group. Except for normal group， gouty arthritis model of rats was induced in other groups. Rats in each administration group were given corresponding drugs intragastrically， and rats in the normal group and model group were given equal volume of water intragastrically for 14 consecutive days. The degree of ankle joint swelling， serum level of interleukin-1β （IL-1β） and protein expressions of nuclear factor kappa-B （NF-κB） in synovial tissue were detected， and the histopathological changes of synovium tissue in the ankle joint of rats were observed. The inflammation model was established by stimulating RAW264.7 cells with lipopolysaccharide. After Tongfeng li’an capsules （62.5， 125， 250 μg/mL） were given， the levels of nitric oxide （NO）， reactive oxygen species （ROS） and IL-1β in the cells and protein expression of NF-κB were detected， and NF-κB localization in the cells was also determined. RESULTS Results of in vivo experiment showed that compared with normal group， the swelling degree of the ankle joint， serum IL-1β level and protein expression of NF-κB in synovium tissue were all increased significantly in model group （P＜0.05）； pathological changes such as synovial hyperplasia， edema， vascular congestion， capillary hyperplasia， and increased inflammatory cells were observed. Compared with model group， the levels of above indexes were all decreased significantly in Tongfeng li’an capsules high-dose group （P＜0.05）， and most of the above indexes were significantly reduced in Tongfeng li’an capsules medium-dose and low-dose groups （P＜0.05）； synovial hyperplasia of the ankle joint improved， and the infiltration of inflammatory cells 2019BS044） decreased. Results of in vitro experiment showed that Tongfeng li’an capsule could significantly reduce the levels of NO， ROS and IL-1β and protein expression of NF-κB（P＜0.01）， and inhibit NF- κB nucleation. CONCLUSIONS Tongfeng li’ancapsules have good anti-inflammatory effect on gouty arthritis， and its mechanism may be related to the inhibition of NF-κB signaling pathway activity.

Objectives:To analysis the effect of continuous positive airway pressure (CPAP) on nocturnal blood pressure in patients complicated with obstructive sleep apnea-hypopnea syndrome (OSAHS) and different circadian rhythms of hypertension.Methods:A total of 61 eligible patients were monitored by overnight polysomnography (PSG) at the Sleep Center of the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University between January 2020 and April 2021. During the period of PSG monitoring, continuous non-invasive blood pressure (BP) and heart rate variability (HRV) were monitored simultaneously. Frequency domain analysis was used to measure HRV and low/high frequency was used to indirectly reflect sympathetic activity. According to the nighttime systolic BP decrease rate, patients were divided into three groups: dipper pattern (descent rate ≥10%), non-dipper pattern (descent rate was less than 10% but higher than 0) and reverse dipper pattern (descent rate≤0). The PSG parameters, BP data as well as sympathetic activity etc. were compared within and among groups before and after CPAP treatment. Multiple linear regression analyses were used to explore the influencing factors of antihypertensive effect of CPAP.Results:There were no significant differences in awake systolic BP (SBP) values, the severity of OSAHS, ESS scores, awake sympathetic activity and the other baseline data among the three groups. After CPAP treatment, the mean value of asleep BP in entire group showed a modest decline as compared to the baseline values [SBP decreased 4.6 mmHg (1 mmHg=0.133 kPa); diastolic blood pressure (DBP) decreased 2.4 mmHg, both P<0.001]. Subgroup analysis showed a significant reduction in asleep SBP of 11.1 mmHg and DBP of 4.9 mmHg (both P<0.001) in reverse dipper group, respectively, compared with the baseline values. While in dipper and non-dipper group, there were no significant differences before and after CPAP treatment in terms of BP (both P>0.05). In addition, there was no difference in awake sympathetic activity among three groups, while sleep sympathetic activity showed a gradual increasing trend. Sleep sympathetic activity decreased significantly from baseline after CPAP treatment in reverse dipper group ( P<0.001), while no differences were found in the other two groups before and after treatment. After controlling for baseline data such as age etc., the line regression model showed that the antihypertensive effect of CPAP was correlated with reverse dipper (SBP: β=0.548, P=0.002; DBP: β=0.454, P=0.013) and the improvement of nocturnal MpO 2 (SBP: β=0.410, P=0.046), but not with the severity of OSAHS, daytime sleepiness, or baseline BP values. Conclusion:For patients with moderate to severe OSAHS and hypertension, reverse dipper is an effective indicator to predict the antihypertensive effect of CPAP therapy.
