Objective To compare the factors associated with gestational diabetes mellitus(GDM)between ethnic minorities pregnant women and Han pregnant women in Guizhou.Methods A retrospective analysis was performed in individuals who gave birth in representative hospitals in various regions of Guizhou province from January 2021 to June 2021.A strict screening was carried out according to the inclusion and exclusion criteria,and clinical data were collected from 2673 individuals,including 856 ethnic minorities pregnant women and 1817 Han pregnant women.All the inidviduals were divided into GDM group and non-GDM group according to the results of OGTT at 24～28 weeks of gestation.The results of general information,blood routine,and biochemical examination were compared between the two groups.Results In ethnic minorities in Guizhou region,age,gestational weight gain(GWG)≥11.5 kg,unemployed,pregnancy times≥2,parity times≥2 and irregular prenatal examination during pregnancy were higher,and platelet count was higher,while the total protein(TP)and albumin(ALB)were lower in GDM group than in non-GDM group(P<0.05).Logistic regression analysis showed that unemployed,pregnancy times≥2,parity times≥2,irregular prenatal examination during pregnancy,TP and ALB levels were influencing factors for GDM in ethnic minorities in Guizhou region(P<0.05).In Han pregnant women in Guizhou region,the age,proportion of GWG≥11.5 kg,unemployed,pregnancy times≥2,parity times≥2,irregular prenatal examination during pregnancy,direct bilirubin(D-BIL)and urea nitrogen(BUN)were higher,and in GDM group than in non-GDM group(P<0.05).Logistic regression analysis showed that GWG≥11.5 kg,pregnancy times≥2,parity times=1,parity times≥2,irregular prenatal examination during pregnancy,D-BIL and BUN were influencing factors for GDM in Han pregnant women in Guizhou region(P<0.05).Conclusions The same influencing factors for the occurrence of GDM between ethnic minorities and Han nationality in Guizhou were no occupation,pregnancy and parity times≥2,and irregular prenatal examination during pregnancy.TP and ALB levels were the influencing factors for GDM among ethnic minorities.D-BIL and BUN are the influencing factors for GDM in Han nationality.Ethnic minorities and Han pregnant women in Guizhou region should take personalized prevention and intervention measures to guide GDM monitoring and early intervention.

ObjectiveTo investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and to establish a predictive model. MethodsA total of 217 patients who were diagnosed with decompensated hepatitis C cirrhosis and were admitted to The Third People’s Hospital of Kunming l from January， 2019 to December， 2022 were enrolled， among whom 63 patients who were readmitted within at least 1 year and had no portal hypertension-related complications were enrolled as recompensation group， and 154 patients without recompensation were enrolled as control group. Related clinical data were collected， and univariate and multivariate analyses were performed for the factors that may affect the occurrence of recompensation. The independent-samples t test was used for comparison of normally distributed measurement data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and the receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model. ResultsAmong the 217 patients with decompensated hepatitis C cirrhosis， 63 （29.03%） had recompensation. There were significant differences between the recompensation group and the control group in HIV history （χ²=4.566， P=0.034）， history of partial splenic embolism （χ²=6.687， P=0.014）， Child-Pugh classification （χ²=11.978， P=0.003）， grade of ascites （χ²=14.229， P<0.001）， albumin （t=4.063， P<0.001）， prealbumin （Z=-3.077， P=0.002）， high-density lipoprotein （t=2.854， P=0.011）， high-sensitivity C-reactive protein （Z=-2.447， P=0.014）， prothrombin time （Z=-2.441， P=0.015）， carcinoembryonic antigen （Z=-2.113， P=0.035）， alpha-fetoprotein （AFP） （Z=-2.063， P=0.039）， CA125 （Z=-2.270， P=0.023）， TT3 （Z=-3.304， P<0.001）， TT4 （Z=-2.221， P=0.026）， CD45⁺ （Z=-2.278， P=0.023）， interleukin-5 （Z=-2.845， P=0.004）， tumor necrosis factor-α （Z=-2.176， P=0.030）， and portal vein width （Z=-5.283， P=0.005）. The multivariate analysis showed that history of partial splenic embolism （odds ratio ［OR］=3.064， P=0.049）， HIV history （OR=0.195， P=0.027）， a small amount of ascites （OR=3.390， P=0.017）， AFP （OR=1.003， P=0.004）， and portal vein width （OR=0.600， P<0.001） were independent influencing factors for the occurrence of recompensation in patients with decompensated hepatitis C cirrhosis. The ROC curve analysis showed that HIV history， grade of ascites， history of partial splenic embolism， AFP， portal vein width， and the combined predictive model of these indices had an area under the ROC curve of 0.556， 0.641， 0.560， 0.589， 0.745， and 0.817， respectively. ConclusionFor patients with decompensated hepatitis C cirrhosis， those with a history of partial splenic embolism， a small amount of ascites， and an increase in AFP level are more likely to experience recompensation， while those with a history of HIV and an increase in portal vein width are less likely to experience recompensation.

ObjectiveTo investigate the association between albumin （Alb） and recompensation by comparing recompensation rate between hepatitis B/C virus-related decompensated liver cirrhosis patients with different Alb levels， and to provide guidance for the identification and management of high-risk patients in clinical practice. MethodsRelated clinical data were collected from 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis who attended The Third People’s Hospital of Kunming from January 1， 2016 to December 31， 2022， and they were divided into three groups based on the level of Alb. The linear regression analysis and chi-square test were used for trend tests. The Kaplan-Meier curve was plotted for the cumulative incidence rate of recompensation in the three groups， and the log-rank test was used for comparison between groups. A Cox proportional-hazards regression model analysis was used to investigate the association between Alb and recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis. ResultsAmong the 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis， 270 achieved recompensation， with a recompensation rate of 36.8%. All patients had a median Alb level of 29.90 （25.90 — 34.80） g/L on admission， and according to the level of Alb， they were divided into <25.9 g/L group with 177 patients， 25.9 — 34.8 g/L group with 377 patients， and >34.8 g/L group with 180 patients； 36 patients （20.3%） in the <25.9 g/L group， 138 （36.6%） in the 25.9 — 34.8 g/L group， and 96 （53.3%） in the >34.8 g/L group achieved recompensation， and the recompensation rate increased with the increase in Alb level （χ²=41.730， P<0.001）. After adjustment for all confounding factors， compared with the <25.9 g/L group， there was a significant increase in the incidence rate of recompensation in the 25.9 — 34.8 g/L group （hazard ratio ［HR］=1.842， 95% confidence interval ［CI］： 1.274 — 2.663） and the >34.8 g/L group （HR=2.336， 95% CI： 1.575 — 3.463）. The Kaplan-Meier survival analysis showed that there was a significant difference in the cumulative incidence rate of recompensation between the three groups （χ²=41.632， P<0.001）. ConclusionAlb level is an influencing factor for recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis， and the recompensation rate increases with the increase in Alb level.

Objective:To explore the value of three-dimensional automatic right ventricular quantitive analysis（3D Auto RVQ）technology in predicting the improvement of left ventricular ejection fraction（LVEF）in patients with heart failure with reduced ejection fraction（HFrEF）.Methods:A retrospective analysis was conducted on 89 HFrEF patients admitted to the Cardiology Department of Central China Fuwai Hospital of Zhengzhou University from April 2022 to June 2024. All patients received medication treatment and were further divided into heart failure with improved ejection fraction（HFimpEF）group and non HFimpEF group based on changes detected by echocardiography in LVEF after treatment. The clinical data，biological indicators，and medication treatment status of patients were collected，routine echocardiographic parameters and right ventricular strain parameters were measured，3D right ventricular ejection fraction（3D-RVEF），3D right ventricular stroke volume index（3D-RVSVI），3D right ventricular end-diastolic volume index（3D-RVEDVI），3D right ventricular end-systolic volume index（3D-RVESVI），3D tricuspid annular plane systolic excursion（3D-TAPSE），and 3D right ventricular fractional area change（3D-RVFAC）were measured using 3D Auto RVQ technology. The differences of the above parameters between the two groups were compared. The ROC curve was used to analyze the predictive efficiency of right ventricular parameters for HFimpEF，and the area under ROC curve（AUC）was calculated and compared. Logistic regression models were used to analyze the predictive value of right ventricular parameters for HFimpEF.Results:Compared with the non HFimpEF group，the HFimpEF group had a younger age，shorter heart failure course，a smaller proportion of males，New York Heart Association（NYHA）functional class ≥Ⅲ，and patients with concomitant coronary heart disease. The baseline LVEF，absolute value of two dimensional right ventricular global longitudinal strain（2D-RVGLS），3D-RVEF，3D-TAPSE，and 3D-RVSVI were higher in the HFimpEF group（all P<0.05）. ROC curve analysis showed that the AUC of 3D-RVEF for predicting HFimpEF was 0.858，and the predictive efficiency was higher than other right ventricular parameters. According to the Yoden index，the optimal cutoff value for predicting HFimpEF based on 3D-RVEF was 36.2%，with a corresponding sensitivity of 84.0% and specificity of 75.0%. After adjusting for clinical and other echocardiographic parameters，the logistic regression model showed that 3D-RVEF was an independent predictor of HFimpEF（ OR=1.435，95% CI=1.145-1.800， P<0.05）. Conclusions:The 3D-RVEF evaluated by 3D Auto RVQ technology has high predictive value for HFimpEF，which can provide a reference for clinical treatment，thereby improving the prognosis of HFrEF patients.

Background::Reperfusion therapy is fundamental for ST-segment elevation myocardial infarction (STEMI). However, the details of contemporary practice and factors associated with reperfusion therapy in China are largely unknown. Therefore, this study aimed to explore reperfusion practice and its associated factors among hospitalized patients with STEMI in China.Methods::Patients with STEMI who were admitted to 159 tertiary hospitals from 30 provinces in China were included in the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome project from November 2014 to December 2019. The associations of the characteristics of patients and hospitals with reperfusion were examined using hierarchical logistic regression. The associations between therapies and in-hospital major adverse cardiovascular events were examined with a mixed effects Cox regression model.Results::Among the 59,447 patients, 37,485 (63.1%) underwent reperfusion, including 4556 (7.7%) receiving fibrinolysis and 32,929 (55.4%) receiving primary percutaneous coronary intervention (PCI). The reperfusion rate varied across geographical regions (48.0%-73.5%). The overall rate increased from 60.0% to 69.7% from 2014 to 2019, mainly due to an increase in primary PCI within 12 h of symptom onset. Timely PCI, but not fibrinolysis alone, was associated with a decreased risk of in-hospital major adverse cardiovascular events compared with no reperfusion, with an adjusted hazard ratio (95% confidence interval) of 0.64 (0.54,0.76) for primary PCI at <12 h, 0.53 (0.37,0.74) for primary PCI at 12 to 24 h, 0.46 (0.25,0.82) for the pharmaco-invasive strategy, and 0.79 (0.54,1.15) for fibrinolysis alone.Conclusions::Nationwide quality improvement initiatives should be strengthened to increase the reperfusion rate and reduce inequality in China.Trial registration::www.ClinicalTrials.gov, NCT02306616

Programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) blocking therapy has become a major pillar of cancer immunotherapy. Compared with antibodies targeting, small-molecule checkpoint inhibitors which have favorable pharmacokinetics are urgently needed. Here we identified berberine (BBR), a proven anti-inflammation drug, as a negative regulator of PD-L1 from a set of traditional Chinese medicine (TCM) chemical monomers. BBR enhanced the sensitivity of tumour cells to co-cultured T-cells by decreasing the level of PD-L1 in cancer cells. In addition, BBR exerted its antitumor effect in Lewis tumor xenograft mice through enhancing tumor-infiltrating T-cell immunity and attenuating the activation of immunosuppressive myeloid-derived suppressor cells (MDSCs) and regulatory T-cells (Tregs). BBR triggered PD-L1 degradation through ubiquitin (Ub)/proteasome-dependent pathway. Remarkably, BBR selectively bound to the glutamic acid 76 of constitutive photomorphogenic-9 signalosome 5 (CSN5) and inhibited PD-1/PD-L1 axis through its deubiquitination activity, resulting in ubiquitination and degradation of PD-L1. Our data reveals a previously unrecognized antitumor mechanism of BBR, suggesting BBR is small-molecule immune checkpoint inhibitor for cancer treatment.

Objective:To explore the curative effect of 0.13 MPa hyperbaric oxygen (HBO) therapy on patients who are not suitable for conventional HBO therapy.Methods:A total of 143 patients were given mild HBO therapy, with 10 minutes of compression and 10 minutes of decompression, and pure oxygen inhalation (30 min×2, 5 min break) in constant pressure period.Results:Among these patients, 2 cases made a full recovery, 19 cases showed significant improvements, 82 cases showed some improvements, and 40 cases showed no improvement. The total effective rate was 72.0%.Conclusion:Mild HBO therapy has a certain effect on hypoxic-ischemic diseases such as sudden deafness, cerebral infarction, cerebral hemorrhage, brain injury, cervical spondylosis, and lumbar spondylosis. Mild hyperbaric oxygen therapy is one of the basic modes of clinical application of HBO, which is worthy of further exploration and practice.
