Objective :
To investigate the effects of microRNA-29a(miR-29a) in mediating the regulation of dihydroartemisinin(DHA) on the immune checkpoint molecule B7H3 in lung adenocarcinoma(LUAD).
Methods:
The expression level and prognostic significance of B7H3 in LUAD were analyzed by public database. Small interfering RNA(siRNA) was used to knock down B7H3 in LUAD cell lines A549 and HCC827, and cell proliferation was detected by CCK-8 method. A549 and HCC827 cells were treated with gradient concentrations of DHA(0, 5, 10, 25, 50, 100 μmol/L) for 48 h, and the half maximal inhibitory concentrate(IC50) was calculated. A549 and HCC827 cells were treated with IC50concentration of DHA for 1, 2 and 3 days, and the cell proliferation was detected by CCK-8 method. A549 and HCC827 cells were transfected with miR-29a inhibitor. After DHA treatment, the expression level of miR-29a was detected by RT-qPCR, and the expression level of B7H3 was detected by Western blot.
Results :
B7H3 was overexpressed in LUAD and associated with poor prognosis. After knocking down of B7H3, the proliferation ability of A549 and HCC827 cells significantly decreased(allP<0.001). DHA inhibited the proliferation of A549 and HCC827 cells in both dose-and time-dependent manners, with IC50values of 30.16 μmol/L and 7.50 μmol/L, respectively. DHA up-regulated the expression of miR-29a in A549 and HCC827 cells(P<0.001,P<0.01), and down-regulated the expression of B7H3 in both cell lines(P<0.01,P<0.001). After transfection of miR-29a inhibitor into A549 and HCC827 cells, the expression of B7H3 was up-regulated, and the down-regulation of B7H3 by DHA was partially reversed.
Conclusion
miR-29a mediates the molecular regulation of DHA on B7H3 in LUAD.

ObjectiveBased on ultra performance liquid chromatography-mass spectrometry(UPLC-MS) and non-targeted metabolomics technology to discuss the central regulatory effect of Chaishao Liujuntang on chronic atrophic gastritis(CAG) rats with liver-depression and spleen-deficiency, and to look for the correlation between cerebral cortex, hypothalamus and metabolic status of gastric tissues. MethodA CAG rat model with liver-depression and spleen-deficiency was established by chemical induction, hunger and satiety disorders, chronic restraint and tail clamping stimulation, lasting for 16 weeks. Twenty-eight Wistar rats were randomly divided into a blank group of 8 rats and a model group of 20 rats. After the completion of modeling, 4 rats in the model group were taken to observe the pathological changes of gastric mucosa. The remaining model rats were randomly divided into a model group of 8 rats and a Chaishao Liujuntang group of 8 rats. Chaishao Liujuntang group rats were given 5.1 g·kg-1 by gavage, and the remaining rats were given equal volume sterilized water by gavage for 4 weeks. Macroscopic characteristics, behavioral indicators and histopathological changes of the gastric mucosa of rats in each group were observed and compared. UPLC-MS non-targeted metabolomics was used to explore the metabolic regulation effect of Chaishao Liujuntang on the cerebral cortex, hypothalamus and stomach tissues of CAG rats with liver-depression and spleen-deficiency. Pearson correlation coefficient method was used to analyze the correlation between different tissue metabolites. ResultCompared with the model group, the macroscopic characteristics of rats in Chaishao Liujuntang group were improved, such as hair color, mental state and stool properties, and the number of times of crossing and standing in the open field experiment was significantly increased, and the static time of forced swimming was significantly reduced(P<0.01), and the gastric mucosa atrophy was reduced. The metabolic data from the cerebral cortex of rats in each group identified a total of 3 common potential biomarkers, but not enriched in pathways, 26 common potential biomarkers were identified in the hypothalamus, and the key metabolic pathways involved were mainly enriched in purine metabolism, glycerol phospholipid metabolism, D-glutamine and D-glutamic acid metabolism. Seventeen common potential biomarkers were identified in the stomach, and the key metabolic pathways involved were mainly enriched in thiamine metabolism, valine, leucine and isoleucine biosynthesis, and taurine and taurine metabolism. Correlation analysis of metabolites in different tissues revealed that multiple amino acids and their derivatives mediated metabolic connections between the cerebral cortex, hypothalamus and stomach of rats. ConclusionThe metabolic disorders in the cerebral cortex, hypothalamus and stomach of CAG rats with liver-depression and spleen-deficiency have their own characteristics, mainly manifested by changes in the content of glycerol phospholipids, fatty acids and bile acid metabolites. Moreover, Chaishao Liujuntang may play a central regulatory role in CAG rats with liver-depression and spleen-deficiency by correcting the metabolic disorders of amino acids.

ObjectiveTo analyze the long-term trends of the disease burden of diabetes attributed to metabolic factors in China from 1990 to 2019, and provide scientific recommendations for diabetes prevention and control in China. MethodsDescriptive analysis was conducted on the disease burden data of diabetes attributed to metabolic factors in China from 1990 to 2019, obtained from GBD 2019, encompassing death form diabetes, disability-adjusted life years (DALY), years of life lost (YLL), and years lived with disability (YLD). Joinpoint regression models were employed to analyze the long-term trends in mortality and DALY rates. Furthermore, the study examined the impact of two metabolic risk factors, high fasting plasma glucose (FPG) levels and high body mass index (BMI) levels, on the disease burden of diabetes. ResultsFrom 1990 to 2019, the overall standardized mortality and DALY rates attributed to metabolic factors for diabetes in the general population in China showed an upward trend, with both average annual percent changes (AAPCs) of 0.1% in the total population. The trend was upward in males with AAPCs of 0.9% and 0.6%, while it was downward in females with AAPCs of -0.4% and -0.3%. As age increased, the disease burden of diabetes attributed to metabolic factors showed an upward trend, with high FPG and high BMI ranking as the top two attributing risk factors. The disease burden of diabetes attributed to metabolic factors was higher in Chinese males than females. ConclusionThe disease burden of diabetes attributed to metabolic factors is increasing among the overall population and particularly among males, while the burden for female is declining. There is a need to increase intervention efforts for males aged 65 and above, provide scientific guidance on residents’ diet and lifestyle habits, and control blood glucose and body weight.

This article reports the diagnosis and treatment of a case of acromegaly in a pregnant patient who took bromocriptine during pregnancy and delivered successfully. A retrospective summary of the clinical data and treatment outcomes before and after two pregnancies of the patient is provided. The patient took bromocriptine during the second pregnancy, and her condition remained stable. A baby girl was delivered by caesarean section at full term. The article suggests that pregnancy in acromegaly patients, after the stabilization of the condition, can lead to favorable outcomes. The use of dopamine receptor agonists during pregnancy does not increase adverse events during the perinatal period.

Objective:To analyze the changes of diagnosis and treatment before and after renal biopsy in adult patients with acute kidney disease (AKD), and to explore the value of renal biopsy in the diagnosis and treatment of AKD.Methods:It was a single-center retrospective observational study. The adult patients with AKD who underwent renal biopsy in the Department of Nephrology of the First Affiliated Hospital of Nanjing Medical University from January 1, 2017 to December 31, 2021 were enrolled. Demographic data, general clinical data, laboratory tests, and diagnosis and treatment data before and after renal biopsy were collected to analyze the concordance rate between clinical and pathological diagnoses, changes in treatment after renal biopsy, and bleeding complication.Results:A total of 575 patients diagnosed with AKD by renal biopsy were included in this study, with age of 51 (36, 63) years old and 359 males (62.4%). Among them, there were 293 patients (51.0%) of acute kidney injury, 348 patients (60.5%) of hypertension and 124 patients (21.6%) of diabetes. The peak serum creatinine was 272 (190, 477) μmol/L. The hemoglobin was 106 (86, 126) g/L. The 24-hour urine protein was 2.15 (0.79, 4.82) g. There were 347 patients (60.3%) of acute glomerular diseases, 136 patients (23.7%) of acute interstitial nephritis, 47 patients (8.2%) of thrombotic microangiopathy, and 45 patients (7.8%) of acute tubular necrosis. The most common types of acute glomerular diseases were IgA nephropathy and anti-neutrophil cytoplasmic antibody-associated glomerulonephritis, accounting for 22.3% (128/575) and 12.2% (70/575), respectively. The clinical diagnoses before renal biopsy were consistent with the renal histopathological diagnoses in 454 patients, with an accuracy rate of 79.0%. Following the renal biopsy, the treatment plan involving glucocorticoids or immunosuppressants was adjusted in 394 patients (68.5%). Significant post-biopsy bleeding occurred in 15 patients (2.6%), with 12 patients requiring blood transfusion and 1 patient requiring surgical intervention.Conclusions:Twenty-one clinical diagnoses do not match the pathological diagnoses in adult AKD patients, 68.5% of patients have changes in their treatment plans, and 2.6% of patients have significant hemorrhagic complications after renal biopsy. Clinicians need to carefully consider the benefits and risks and make individualized decisions about renal biopsy.
