ABSTRACT

Based on UPLC-Q-orbitrap-MS and biological network analysis tools, the mechanism of Xihuang Pill in improving hyperplasia of mammary glands was systematically analyzed. The rat model of hyperplasia of mammary glands was established by intramuscular injection of estradiol benzoate and progesterone. LC-MS tissue metabolomics was used to explore the key metabolites and metabolic pathways of Xihuang Pill in improving hyperplasia of mammary glands in rat. The network analysis of the key metabolites regulated by Xihuang Pill was carried out by integrating biological network analysis tools, focusing on the key metabolic pathways, and exploring the potential targets of Xihuang Pill to improve hyperplasia of mammary glands. Compared with the control group, there were significant differences in the content of 49 differential metabolites in the tissues of the model group (P < 0.05). Xihuang Pills could significantly call back 17 metabolites such as L-alanine, threonine, indole-3-carboxylic aldehyde, lysine, arginine, alanylleucine, glycyltyrosine, γ-glutamyl leucine, vitamin B3, serine leucine, threonine leucine, isoleucine glutamic acid, γ-glutamyl tyrosine, decanoyl-L-carnitine, uric acid, leucylleucine, S-adenosyl-methionine. Further network analysis and literature research on the key metabolites regulated by Xihuang Pills showed that the AGE-RAGE signaling pathway may be one of the important pathways for Xihuang Pills to improve hyperplasia of mammary glands. STAT3, MAPK1, EGFR, CASP3, CASP8, PRKCA and JUN in the AGE-RAGE signaling pathway may be potential targets for Xihuang Pills to improve hyperplasia of mammary glands. The animal experiment operations involved in this paper follow the provisions of the Animal Ethics Committee of Gansu University of Traditional Chinese Medicine and pass the ethical review of animal experiments (approval number: 2022-705).

ABSTRACT

ObjectiveTo observe the effect of Banxia Xiexintang (BXT) on the proliferation of human gastric cancer HGC-27, MKN-45, and AGS cells and its mechanism. MethodCell counting kit-8 (CCK-8) was used to detect the effects of different concentrations of BXT-containing serum (5%, 10%, and 20%) on the proliferation of HGC-27, MKN-45, and AGS cells. A mitochondrial membrane potential probe (TMRE) was used to detect the expression of mitochondrial membrane potential in cells. A kit was used to detect iron ion (Fe2+) content, lipid peroxide (LPO), and superoxide dismutase (SOD) activity. Western blot was used to detect the protein expression levels of glycogen synthase3β (GSK3β), phosphorylated GSK3β (p-GSK3β), nuclear factor E2 related factor 2 (Nrf2), and glutathione peroxidase 4 (GPX4). The real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of member 11 of the cystine/glutamic acid reverse transporter solute vector family 7 (SLC7A11), member 2 of the heavy chain solute vector family 3 (SLC3A2), transferrin receptor 3 (TFRC), and tumor protein (TP)53. ResultCCK-8 results showed that BXT and capecitabine could significantly reduce the survival rate of three kinds of gastric cancer cells after treatment with drug-containing serum for 24 h (P<0.01). After 48 h of intervention with drug-containing serum, the survival rate of three kinds of gastric cancer cells was significantly decreased in both the capecitabine group and the BXT group compared with the blank group. The BXT group was dose-dependent, with 20% BXT having the most significant effect (P<0.01). In terms of biochemical indicators of ferroptosis, compared with the blank group, BXT and capecitabine significantly decreased the expression of mitochondrial membrane potential (P<0.01) and SOD activity (P<0.01) and significantly increased the contents of LPO and Fe2+ (P<0.01), so as to improve the sensitivity of gastric cancer cells to ferroptosis. In terms of the Nrf2/GPX4 pathway, compared with the blank group, the BXT group could reduce the protein expressions of p-GSK3β, Nrf2, and GPX4 (P<0.01) in gastric cancer cells and increase mRNA expressions of SLC7A11 and SLC3A2 (P<0.05). It could also increase the protein expression of GSK3β (P<0.01) and mRNA expression of TP53 and TFRC (P<0.05, P<0.01) in gastric cancer cells. Inhibition of the Nrf2/GPX4 pathway induces ferroptosis in gastric cancer cells. Compared with the capecitabine group, the 20% BXT group showed a more obvious effect. ConclusionBanxia Xiexintang can induce ferroptosis in gastric cancer cells HGC-27, MKN-45, and AGS by inhibiting the Nrf2/GPX4 pathway.

ABSTRACT

Acute-on-chronic liver failure (ACLF) is a clinical syndrome of acute decompensation accompanied by organ failure that occurs on the basis of chronic liver disease and has a high short-term mortality rate. Currently, there are still differences in relation to the definition of ACLF; thus, baseline characteristics and dynamic changes are important bases for clinical decision-making in patients with liver transplantation and others. The basic strategies for treating ACLF currently include internal medicine treatment, artificial liver support systems, and liver transplantation. Multidisciplinary active collaborative management throughout the whole course is of great significance for further improving the survival rate in patients with ACLF.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis.@*METHODS@#From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up.@*RESULTS@#Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them.@*CONCLUSION@#In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

ABSTRACT

Caused by endocrine disorder, hyperplasia of mammary glands(HMG) tends to occur in the young with increasing incidence, putting patients at the risk of cancer and threatening the health of women. Therefore, the prevention and treatment of HMG is attracting more and more attention. Amid the modernization of traditional Chinese medicine(TCM), many scholars have found that Chinese patent medicine has unique advantages and huge potential in treatment of endocrine disorder. Particularly, Chinese patent medicine with the function of blood-activating and mass-dissipating, such as Xiaojin Pills and Xiaozheng Pills, has been commonly used in clinical treatment of HMG, which features multiple targets, obvious efficacy, small side effect, and ease of taking and carrying around. Clinical studies have found that the combination of Chinese patent medicine with other medicine can not only improve the efficacy and relieve symptoms such as hyperplasia and pain but also reduce the toxic and side effects of western medicine. Therefore, based on precious pharmacological research and clinical research, this study reviewed the mechanisms of blood-activating mass-dissipating Chinese patent medicine alone and in combination with other medicine, such as regulating levels of in vivo hormones and receptors, promoting apoptosis, inhibiting angiogenesis, improving hemorheology indexes, enhancing immunity, and boosting antioxidant ability. In addition, limitations and problems were summarized. Thereby, this study is expected to lay a theoretical basis for the further study and clinical application of blood-activating mass-dissipating Chinese patent medicine alone or in combination with other medicine against HMG.

ABSTRACT

Objective: To explore the family rehabilitation model for children with scar contracture after hand burns and observe its efficacy. Methods: A retrospective non-randomized controlled study was conducted. From March 2020 to March 2021, 30 children with scar contracture after deep partial-thickness to full-thickness burns of hands, who met the inclusion criteria, were hospitalized in the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University. According to the rehabilitation model adopted, 18 children (23 affected hands) were included in a group mainly treated by family rehabilitation (hereinafter referred to as family rehabilitation group), and 12 children (15 affected hands) were included in another group mainly treated by hospital rehabilitation (hereinafter referred to as hospital rehabilitation group). In the former group, there were 11 males and 7 females, aged (4.8±2.1) years, who began rehabilitation treatment (3.1±0.8) d after wound healing; in the latter group, there were 7 males and 5 females, aged (4.6±2.1) years, who began rehabilitation treatment (2.8±0.7) d after wound healing. The children in hospital rehabilitation group mainly received active and passive rehabilitation training in the hospital, supplemented by independent rehabilitation training after returning home; after 1-2 weeks of active and passive rehabilitation training in the hospital, the children in family rehabilitation group received active and passive rehabilitation training at home under the guidance of rehabilitation therapists through WeChat platform. Both groups of children were treated for 6 months. During the treatment, they wore pressure gloves and used hand flexion training belts and finger splitting braces. Before treatment and after 6 months of treatment, the modified Vancouver scar scale, the total active movement of the hand method, and Carroll quantitative test of upper extremity function were used to score/rate the scar of the affected hand (with the difference of scar score between before treatment and after treatment being calculated), the joint range of motion (with excellent and good ratio being calculated), and the function of the affected limb, respectively. Data were statistically analyzed with independent sample t test, equivalence test, Fisher's exact probability test, and Mann-Whitney U test. Results: The differences of scar scores of the affected hands of children in family rehabilitation group and hospital rehabilitation group between after 6 months of treatment and those before treatment were 3.0 (2.0, 7.0) and 3.0 (2.0, 8.0) respectively (with 95% confidence interval of 2.37-5.38 and 1.95-5.91). The 95% confidence interval of the difference between the differences of the two groups was -2.43-2.21, which was within the equivalent boundary value of -3-3 (P<0.05). The excellent and good ratios of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group were 3/23 and 2/15 respectively before treatment, and 15/23 and 12/15 respectively after 6 months of treatment. The ratings of joint range of motion of the affected hand of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.58 and 2.30, respectively, P<0.05), but the ratings of joint range of motion of the affected hand between the two groups were similar before treatment and after 6 months of treatment (with Z values of 0.39 and 0.55, respectively, P>0.05). The functional ratings of the affected limbs of children in family rehabilitation group and hospital rehabilitation group after 6 months of treatment were significantly higher than those before treatment (with Z values of 3.98 and 3.51, respectively, P<0.05), but the functional ratings of the affected limbs between the two groups were similar before treatment and after 6 months of treatment (with Z values of 1.27 and 0.38, respectively, P>0.05). Conclusions: The WeChat platform assisted rehabilitation treatment with mainly family rehabilitation, combined with hand flexion and extension brace can effectively reduce the scarring after children's hand burns, improve the joint range of motion of the affected hands, and promote the recovery of affected limb function. The effect is similar to that of hospital-based rehabilitation providing an optional rehabilitation, treatment method for children who cannot continue to receive treatment in hospital.

ABSTRACT

This study aimed to investigate the mechanism of Xihuang Pills in improving hyperplasia of mammary gland(HMG) in rats based on urine metabolomics using ultra-performance liquid chromatography-quadrupole-Orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS). The HMG rat model was established by intramuscular injection of estradiol benzoate solution(0.5 mg·kg~(-1), 25 days) followed by progesterone injection(5 mg·kg~(-1), 5 days). UPLC-Q-Orbitrap-MS technology was used to establish the endogenous small-molecule metabolic profiles in urine samples of rats in the blank group, the HMG model group, and Xihuang Pills group. Multivariate statistical analysis was performed for pattern recognition, t test and variable importance in the projection(VIP) were used to screen potential biomarkers. The significantly changed differential metabolites were identified using the online database Human Metabolome Database(HMDB). Metabolic pathway enrichment analysis was conducted using the MetaboAnalyst 5.0 database. The results showed that 90 differential metabolites with significant changes(P<0.05) were identified between the blank group and the HMG model group using the HMDB. Among them, 48 metabolites significantly reverted(P<0.05) after administration of Xihuang Pills, which may be related to the regulatory effect of Xihuang Pills. Thirteen metabolic pathways significantly associated with HMG were identified when the differential metabolites were imported into the MetaboAnalyst 5.0 database, and Xihuang Pills could modulate seven of these pathways. These metabolic pathways mainly involved histidine metabolism, arginine and proline metabolism, β-alanine metabolism, glycine, serine and threonine metabolism, tryptophan metabolism, pyrimidine metabolism, and amino sugar and nucleotide sugar metabolism. This study utilized UPLC-Q-Orbitrap-MS and urine metabolomics technology to analyze the mechanism of Xihuang Pills in improving HMG, laying the foundation for further in-depth research.

ABSTRACT

In this study, based on network pharmacology and molecular docking method, the mechanism of anti-hyperplasia of mammary glands of Xihuang Pills blood-entering components was explored, and the efficacy and key targets of Xihuang Pills blood-entering components were experimentally verified by MCF-10A proliferation model of human mammary epithelial cells. In order to clarify the material basis and mechanism of Xihuang Pills in realizing anti-hyperplasia of mammary glands, the blood-entering components of Xihuang Pills were qualitatively analyzed by UPLC-Q-TOF-MS, and 22 blood-entering components were identified. By taking the blood-entering components as the research object, the network pharmacology prediction and molecular docking verification were carried out, and finally, three key targets were screened out, namely JAK1, SRC, and CDK1. In vitro experiments show that Xihuang Pills can inhibit the proliferation of MCF-10A cells, promote the apoptosis of MCF-10A cells, and reduce the expression of JAK1, SRC, and CDK1 targets in cells. To sum up, Xihuang Pills can promote the apoptosis of mammary epithelial cells by regulating the expression of JAK1, SRC, and CDK1 and then play an anti-hyperplasia role, which provides an experimental basis for clarifying the material basis of Xihuang Pills for anti-hyperplasia effect.

ABSTRACT

OBJECTIVE@#To investigate whether Salvianolic acid A (SAA) can restore cartilage endplate cell degeneration of intervertebral discs and to identify the mechanism via regulation of micro-RNA.@*METHODS@#Cartilage endplate cells were isolated from lumbar intervertebral disc surgical samples and were treated with serum containing a series of concentrations of SAA (2, 5, and 10 ?M) for 24, 48, and 72 h to identify a proper dose and treatment time of SAA. The effect SAA on interlenkin-1β (IL-1β)-induced extracellular matrix degradation of cartilage endplate cells were analyzed by Alcian blue staining and assessment of the expression levels of ADAMTS-5, MMP3 and Col2a1. Further, the potential target miRNAs were preliminarily screened by micro-RNA sequencing combining qRT-PCR and Western blot, and then, the miRNAs mimics and inhibitors were used to verify the regulatory effect of SAA on potential target miRNAs.@*RESULTS@#The 10 μM SAA treatment for 48 h significantly enhanced the viability of cartilage endplate cells, and increased Col2a1 expression and glycosaminoglycan accumulation that were repressed by IL-1β, and reduced the effect of IL-1β on ADAMTS-5, and MMP3. Screening analysis based on micro-RNA sequencing and Venny analysis identified the downstream micro-RNAs, including miR-940 and miR-576-5p. Then, the miR-940-mimic or miR-576-5p-mimic were transfected into CEPCs. Compared with the SAA group, the expression of ADAMTS-5 and MMP3 increased significantly and the expression of COL2A1 obviously decreased after overexpression of miR-940 or miR-576-5p in CEPCs.@*CONCLUSION@#Salvianolic acid A attenuated the IL-1β-induced extracellular matrix degradation of cartilage endplate cells by targeting regulate the miR-940 and the miR-576-5p.

Acute-on-chronic liver failure (ACLF) is a common clinical syndrome of severe liver disease characterized by a high short-term mortality rate in clinical practice. Therefore, early and accurate evaluation of the prognosis of ACLF patients is of great significance for making clinical decisions and improving prognosis. This article reviews the recent research advances in markers for the prognostic evaluation of ACLF, in order to improve the existing prognostic evaluation system, assist clinicians in providing timely and appropriate clinical intervention, and further reduce the mortality rate of patients.

ABSTRACT

ObjectiveTo investigate the value of MELD 3.0, MELD, and MELD-Na scores in assessing the 90-day prognosis of patients with acute-on-chronic liver failure (ACLF) through a comparative study. MethodsA retrospective analysis was performed for the clinical data of 605 patients with ACLF who were treated in Tianjin Third Central Hospital, The Fifth Medical Center of Chinese PLA General Hospital, and Beijing YouAn Hospital from November 2012 to June 2019, and according to the 90-day follow-up results after admission, they were divided into survival group with 392 patients and death group with 213 patients. The receiver operating characteristic (ROC) curve, the area under the ROC curve (AUC), net reclassification improvement (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA) curve were used to investigate the value of MELD 3.0, MELD, and MELD-Na scores at baseline, day 3, week 1, and week 2 in predicting the prognosis of the disease. ResultsAt day 3 and week 1, MELD 3.0 score had an AUC of 0.775 and 0.808, respectively, with a better AUC than MELD score (P<0.05). At day 3, week 1, and week 2, MELD 3.0 score showed an NRI of 0.125, 0.100, and 0.081, respectively, compared with MELD in predicting the prognosis of ACLF patients, as well as an NRI of 0.093, 0.140, and 0.204, respectively, compared with MELD-Na score in predicting prognosis. At baseline, day 3, week 1, and week 2, MELD 3.0 showed an IDI of 0.011, 0.025, 0.017, and 0.013, respectively, compared with MELD in predicting the prognosis of ACLF patients. At day 3 and week 2, MELD 3.0 showed an IDI of 0.027 and 0.038, respectively, compared with MELD-Na in predicting the prognosis of ACLF patients. All the above NRIs and IDIs were >0, indicating a positive improvement (all P<0.05). DCA curves showed that MELD 3.0 was superior to MELD at day 3 and was significantly superior to MELD-Na at week 2. There was no significant difference in the ability of the three scores in predicting the prognosis of ACLF patients with different types, and there was also no significant difference in the ability of the three scores in predicting the prognosis of ACLF patients with the etiology of HBV infection, alcohol, or HBV infection combined with alcohol, while MELD 3.0 was superior to MELD for ACLF patients with other etiologies (P<0.05). ConclusionMELD 3.0 score is better than MELD and MELD-Na scores in predicting the 90-day survival of patients with ACLF, but with limited superiority.

ABSTRACT

Ma-Mu-Ran Antidiarrheal Capsules (MMRAC) is traditional Chinese medicine that has been used to treat diarrhea caused by acute enteritis (AE) and bacillary dysentery in Xinjiang (China) for many years. However, the potential therapeutic mechanism of MMRAC for AE and its regulatory mechanism on host metabolism is unclear. This study used fecal metabolomics profiling with GC/MS and 16S rRNA gene sequencing analysis to explore the potential regulatory mechanisms of MMRAC on a dextran sulfate sodium salt (DSS)-induced mouse model of AE. Fecal metabolomics-based analyses were performed to detect the differentially expressed metabolites and metabolic pathways. The 16S rRNA gene sequencing analysis was used to assess the altered gut microbes at the genus level and for functional prediction. Moreover, Pearson correlation analysis was used to integrate differentially expressed metabolites and altered bacterial genera. The results revealed that six intestinal bacteria and seven metabolites mediated metabolic disorders (i.e., metabolism of amino acid, carbohydrate, cofactors and vitamins, and lipid) in AE mice. Besides, ten altered microbes mediated the differential expression of eight metabolites and regulated these metabolisms after MMRAC administration. Overall, these findings demonstrate that AE is associated with metabolic disorders and microbial dysbiosis. Further, we present that MMRAC exerts protective effects against AE by improving host metabolism through the intestinal flora.

ABSTRACT

Objective:To investigate the clinical characteristics and risk factors for the progression of acute-on-chronic liver failure(ACLF)associated with hepatitis B in elderly patients.Methods:A total of 168 elderly patients with hepatitis B-related acute-on-chronic liver failure(HBV-ACLF)at Tianjin Third Central Hospital who met the diagnostic criteria of the Asian Pacific Association for the Study of the Liver(APASL)-ACLF were enrolled, 176 non-elderly HBV-ACLF patients served as the control group during the same period, and their baseline and progression data were recorded.At the same time, the elderly group was divided into the progressive subgroup and the non-progressive subgroup based on the diagnostic criteria of the European Society for the Study of the Liver(EASL)-ACLF, and their baseline and progression data were recorded.Independent risk factors for HBV-ACLF progression in the elderly were analyzed using multivariate Cox proportional risk model regression.Results:Compared with non-elderly patients with HBV-ACLF, elderly patients were more likely to progress to meet the EASL-ACLF diagnostic criteria and have higher mortality.Multivariate Cox proportional risk model regression analysis showed that baseline arterial lactic acid levels( HR=1.77, 95% CI: 1.36-2.30, P<0.01), secondary nosocomial infections( HR=13.90, 95% CI: 3.73-51.87, P<0.01), rates of change in maximum total bilirubin( HR=1.08, 95% CI: 1.01-1.15, P=0.04), rates of change in maximum MELD( HR=4.06, 95% CI: 1.53-10.77, P=0.01)and rates of change in maximum CLIF-SOFA( HR=12.74, 95% CI: 2.46-66.08, P<0.01)were independent risk factors for progression of HBV-ACLF in elderly patients. Conclusions:Compared with non-elderly patients, elderly patients with HBV-ACLF have more advanced disease and higher mortality.Therefore, risk factors should be identified as soon as possible and treatment plans should be formulated as soon as possible to further reduce the mortality.

ABSTRACT

Objective To investigate the level of glycosylated albumin (GA) in liver cirrhosis patients with different Child-Pugh classes and its application value in predicting liver function. Methods A total of 486 patients with liver cirrhosis who were hospitalized in Tianjin Third Central Hospital from January 1 to December 31, 2019, were enrolled, among whom 227 patients had liver cirrhosis without diabetes and 259 patients had liver cirrhosis with diabetes. The patients were divided into groups according to Child-Turcotte-Pugh (CTP) score, and fasting blood glucose, glycosylated hemoglobin, and percentage of GA (GA%) were measured. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between three groups, and the Dwass-Steel-Critchlow-Fligner test was used for further comparison between two groups. Scatter plots and fitting curves were plotted for CTP score and GA% to evaluate the association between them and calculate the cut-off value. Results For the cirrhosis patients without diabetes, there were significant differences between the patients with different Child-Pugh classes in GA% ( χ 2 =24.809, P < 0.001), fasting blood glucose ( χ 2 =11.899, P =0.003), and glycosylated hemoglobin ( χ 2 =13.607, P =0.001); further pairwise comparison showed that there was a significant difference in GA% between Child-Pugh class A/B liver cirrhosis patients without diabetes and Child-Pugh class C liver cirrhosis patients ( P < 0.05), Child-Pugh class A patients had a significantly higher level of fasting blood glucose than Child-Pugh class B patients ( P < 0.05), and Child-Pugh class A patients had a significantly higher level of glycosylated hemoglobin than Child-Pugh class B/C patients ( P < 0.05). For the patients with liver cirrhosis and diabetes, there were significant differences between the patients with different Child-Pugh classes in GA% ( χ 2 =10.734, P =0.005) and fasting blood glucose ( χ 2 =16.295, P < 0.001); further pairwise comparison showed that Child-Pugh class C liver cirrhosis patients with diabetes had a significantly lower GA% than Child-Pugh class A/B patients ( P < 0.05) and Child-Pugh class A patients had a significantly lower fasting blood glucose level than Child-Pugh class B patients ( P < 0.05). The fitting curve showed that GA% increased with the increase in CTP score in the liver cirrhosis patients without diabetes, reached the highest value at the CTP score of 6.5, and then started to decrease, with the lower value at the CTP score of 11.5, which showed a curvilinear relationship; in the liver cirrhosis patients with diabetes, GA% first increased and then decreased with the increase in CTP score, with a cut-off value of 8. Conclusion GA% first increases and then decreases along with the progression of liver cirrhosis. There is a significant difference in GA between liver cirrhosis patients with different Child-Pugh classes, suggesting that the reduction in GA is closely associated with liver function decompensation in end-stage liver cirrhosis.
