RESUMO

Objective:To explore the association between serum high density lipoprotein subtype 3 cholesterol (HDL3-C) levels and the severity and in-stent restenosis of patients with coronary artery disease.Methods:124 patients with coronary artery diseases and 62 healthy controls were included in this clinical case-control retrospective study. Participants were hospitalized from November 2020 to November 2021 at Jinling Hospital, Medical School of Nanjing University were enrolled. Patients with coronary artery disease were as follows: 28 patients with acute coronary syndrome and 96 patients with stable coronary heart disease. Serum HDL3-C levels as well as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were determined. According to the coronary artery angiography results of all patients at the time of admission, Gensini scores were calculated and patients were divided into in-stent restenosis group ( n=22), no in-stent stenosis group ( n=23) and non-stent implantation group ( n=79). The correlation between HDL3-C levels and other parameters was analyzed by Pearson or Spearman correlation analyses. Multivariate Logistic regression analyses were used to determine the impact of HDL3-C on the in-stent restenosis of coronary artery diseases. Results:Compared with controls, serum levels of HDL3-C and HDL-C were significantly decreased in patients with coronary artery diseases (all P<0.05). There was a significantly negative correlation between HDL3-C levels and Gensini scores ( r=-0.201, P=0.043). Among patients with coronary artery disease, serum levels of HDL3C, TC and TG in the in-stent restenosis group were significantly lower than in no in-stent stenosis group as well as than in the non-stent implantation group (all P<0.05). Multivariate Logistic regression analyses showed that after adjusting for age, sex, lipid-lowering drugs and TC, TG, LDLC parameters, HDL3-C ( OR=0.885, 95% CI 0.791-0.990, P=0.033) and HDL-C ( OR=0.018, 95% CI 0.001-0.426, P=0.013) levels were both independently associated with the occurrence of coronary artery disease; only HDL3-C levels (no in-stent stenosis group as the reference: OR=0.833, 95% CI 0.698-0.994, P=0.042; non-stent implantation group as the reference: OR=0.812, 95% CI 0.685-0.963, P=0.017) were independently associated with the presence of in-stent restenosis ( P<0.05). Conclusions:Serum HDL3-C levels are decreased in patients with coronary artery disease, especially in patients with in-stent restenosis. HDL3-C levels are associated with the severity of coronary artery lesions and the presence of in-stent restenosis of coronary arteries.

RESUMO

Objective To study the predictive value of umbilical cord blood regulatory T cells (Treg) for bronchopulmonary dysplasia (BPD) in preterm infants. Method From June 2017 to December 2018, premature infants with gestational age less than 32 weeks admitted to NICU of our hospiatal were prospectively selected. The umbilical cord blood was collected at birth to examine the Treg amount. The infants were assigned into BPD group and non-BPD group according to the diagnosis at discharge. The differences of Treg amount between the two groups and different degrees of BPD were analysed. Result A total of 124 premature infants (GA<32 weeks) were admitted, including 41 cases in BPD group (mild, n=18;moderate, n=14; severe, n=9) and 83 cases in the non-BPD group. The BPD group had GA of (29.6 ± 1.1) weeks and birth weight (BW) of (1128 ± 135) g. The non-BPD group had GA of (29.8 ± 1.1) weeks and BW of (1316 ± 180) g. The birth weight, 1min and 5min Apgar scores in BPD group were lower than the non-BPD group (P<0.001). The BPD group had higher incidence of respiratory distress syndrome, longer duration of mechanical ventilation (MV) and oxygen inhalation(P<0.001) than the non-BPD group. The MV duration and oxygen inhalation duration in the severe BPD group were significantly longer than the moderate and mild BPD groups, and the duration in the moderate group was longer than the mild group (P<0.001). The number of Treg in cord blood in the BPD group [(1.43 ± 0.06) × 105 cells/ml] was significantly lower than the non-BPD group [(2.57 ± 0.09) × 105 cells/ml], and the difference was statistically significant (P<0.001). Multivariate Logistic regression analysis showed that a significant decrease in the number of Treg was a risk factor for BPD in premature infants (OR=0.000, 95%CI 0.000 ~ 0.012, P=0.009). The number of Treg in umbilical cord blood was negatively correlated with the severity of BPD. The area under the ROC curve showed that the cut-off value was 1.95 × 105 cells/ml, with Youden index 0.613, sensitivity 85.4% and specificity 75.9%. Conclusion The number of cord blood Treg cells may be a useful biomarker for predicting BPD in premature infants.

RESUMO

Objective]To explore the relationship between Yin-wei theory and clinical practice ,and to discuss how to apply Yin-wei theory to solve practical problems in clinical situation.[Methods]We start from the Traditional Chinese Medicine(TCM) classics Nei Jing(the Canon of Internal Medicine) and Nan Jing(Canon On Eighty-One Difficult Issues),combined with Zhang Zhongjing’s application of Guizhi decoction in his book“Treatise on Febrile and Miscellaneous Diseases”to explore the cause and effect of Yin-wei theory and to comprehensively analyze its underlying thought .[Results]We found that Guizhi decoction in the“Treatise on Febrile Diseases”was not only applied in the chapter Taiyang disease,but also involved in other four chapters of Shaoyin disease and the chapter of cholera disease.In“Synopsis of Golden Chamber”,Guizhi decoction was used to treat vomitus gravidarum and affection by cold after delivery,while in Zhongjing’s practice,Guizhi decoction derived formula was widely used in the treatment of consumptive internal injuries miscellaneous disease,indicating that many internal injuries miscellaneous diseases were closely related to external infection .Tonic medicines were rarely seen alone in classical consumptive disease treatment.[Conclusion]Practice has proven that deep learning and understanding of Yin-wei theory has great guiding significance for us to put knowledge in TCM classic theories into clinical practice .Yin-wei theory opens an important window to learn“Treatise on Febrile and Miscellaneous Diseases”and trains clinical thinking,which is worth further discussion.

RESUMO

Objective To investigate the role of epigallocatechin gallate ( EGCG) in reversing the CpG island methylation of Rad23b and Ddit3 gene promoter and its mRNA expression induced by 0?5 Gy X-rays. Methods Thirty BALB/c male mice were randomly divided into 6 groups: control group, irradiation group, low/high dose of EGCG group, low/high dose of EGCG with irradiation group. For the irradiation group, mice were fractionally exposed with 6 MV X-rays for 10 d (0?05 Gy/d × 10 d). 2 hours after the final irradiation, all mice were killed and such tissues as blood, kidney, liver, spleen, brain, and lung were collected. Methylation and expression levels of Rad23b and Ddit3 were measured by bisulfate sequencing primers ( BSP) and Real-time PCR, respectively. Results Compare to the control group, Rad23b was hypermethylated in PBMC, liver, spleen, brain and lung (t= -20?19, -14?80, -12?05,-28?42, -12?58, P<0?05) in the irradiation group. Meanwhile, its mRNA expression level was down-regulated in PBMC, liver, brain and lung (t=25?25, 17?43, 11?53, 22?85, P<0?05). Similarly, a significant hypermethylation change of Ddit3 was observed in PBMC, liver and lung after irradiation ( t=-52?89, -20?31, -3?85, P<0?05) so that the mRNA expression of Ddit3 decreased in PBMC and liver ( t = 11?89, 16?52, P < 0?05 ). Compared to the irradiation group, EGCG with different concentrations of 10, 20 mg/kg significantly reduced the methylation level of Rad23b and Ddit3 ( t =-13?39-7?99, P<0?05), and induced re-expression of mRNA (t= -34?02 - -2?89, P<0?05). This change was more notable in the irradiation group with the high dose of EGCG. Conclusions As a natural drug, EGCG may play an important role in affecting DNA methylation and hence protects DNA from radiation damage.

RESUMO

Objective The invasion and metastasis of colon cancer often leads to treatment failure and mortality in patients . Our research is to investigate the influence of FoxM 1 to malignant human colon cancer line . Methods In two human colon cancer lines, the protein and mRNA expression levels of FoxM 1 were analyzed with the application of RT-PCR and Western blot , from which high-expressed HT-29 and low-expressed HCT-116 were determined.The expression of FoxM1 was down-regulated by RNA interfering in HT-29 and up-regulated by constructing overexpression transgenic line in HCT-116.The proliferation of the above cells was assayed by healing method;while the metastasis and invasion ability were examined by Transwell chamber assay . Results Two colon cancer lines were selected with high-expression or low-expression of FoxM1 separately named HT-29 and HCT-116.Application of PEX-2-FoxM1 raised after HCT-116 cells express FoxM1, cell scratches in HCT-116 experimetal group ([70.92 ±1.48]%) compared with HCT-116 control group([16.92 ±4.05]%)and HCT-116 blank control group([16.66 ±2.63]%) will markedly enhance its capabil-ity of healing (P<0.05), Transwell Chambers in membrane cells in HCT-116 experimetal group (186.0 ±6.8) compared with HCT-116 control group(42.0 ±2.0) and HCT-116 blank control grou (37.0 ± 2.2)was increased (P<0.05).On the other hand, the applied pG-PH-shFoxM1 can reduce FoxM1 expression in HT-29 cell, cell scrat-ches healing ability in HT-29 experimetal group ( [ 10 .37 ± 3.86]%) compared with HT-29 control group([34.63 ±2.35]%)and HT-29 blank control group([67.36 ±2.61]%) decreased significantly (P<0.05), Transwell Chambers in membrane cells in HT-29 experimetal group (53.0 ±1.8)compared with HT-29 control group(95.0 ±2.2)and HT-29 blank control grou(118.0 ±4.0) was also reduced (P<0.05). Conclusion The expression of FoxM1 is in close relation to the invasion and metastasis of CRC .The fact that the siRNA interfering FoxM1 could effectively inhibit the proliferation, metastasis and invasion, suggesting FoxM1 could po-tentially be a new molecular target for inhibiting the proliferation of human colon cancer line .

RESUMO

AIM: To investigate whether ?-tyrosol could induce expression of DT-diaphorase (NQO 1) gene and inhibit proliferation of hepatoma cells and their relationship.METHODS: The DT-diaphorase activity, mRNA expression and cell proliferation were examined using direct measurement of DT-diaphorase from cells cultured in microtiter wells, semi-quantitative reverse transcription-PCR (RT-PCR) technique and crystal violet assay after treatment of SMMC-7721 cells with ?-tyrosol for 24 h. RESULTS: Treatment of SMMC-7721 cells with ?-tyrosol caused an increase in DT-diaphorase activity and DT-diaphorase mRNA expression in a dose-dependent manner. A statistically significant correlation between DT-diaphorase mRNA levels and enzyme activities was evident. In almost the same concentration range of 70 mg/L to 100 mg/L, ?-tyrosol resulted in a dose-dependent inhibition of cell proliferation which well inversely correlated with DT-diaphorase activity.CONCLUSION: ?-tyrosol can induce DT-diaphorase activity and enhance expression of its gene, which may contribute to antiproliferation of hepatoma cells caused by the same chemical.
