2. Study on quality markers of ginseng acting on heart failure based on TCMIP V2.0
Chinese Traditional and Herbal Drugs 2019;50(19):4628-4633
Objective: To predict the possible quality markers of ginseng in the treatment of heart failure. Methods: The ginseng chemical information was used to predict its putative targets related to heart failure by TCMIP V2.0 and the protein-protein interaction (PPI) network was constructed. The key targets of drug intervention on heart failure were enriched. The interaction network of chemical components-key targets-pathways was constructed to obtain the main components acting on these key targets, which are related to drug efficacy. According to the five principles of quality markers identification, we analyzed the quality markers of ginseng in the treatment of heart failure. Results: A total of 63 key targets were obtained for ginseng in the treatment of heart failure, including 63 putative drug targets and two targets related to disease. ATP1A1 and ADCY2 are the common targets associated with the drug and disease. The common targets of ATP1A1 and ADCY2 may be the key targets of drug acting on disease. The main components of ginseng acting on these common targets were screened out, and then we have determined the possible quality markers of ginseng for the treatment of heart failure based on the five principles of quality markers. Conclusion: We obtained the possible quality markers of ginseng in the treatment of heart failure, including ginsenoside Rg1, ginsenoside Re, ginsenoside Rf, and ginsenoside Rb2, which provided the basis for our deeper research of ginseng in the treatment of heart failure.

OBJECTIVEOver the last few decades, diabetic cardiomyopathy has been identified as a significant contributor in cardiac morbidity. However, the mechanisms of diabetic cardiomyopathy have not been clarified.
METHODSIn the present study, a diabetic rat model was induced by the intraperitoneal injection of streptozotocin. The myocardial CD147 expression and extent of glycosylation, as well as thematrixmetalloproteinases(MMPs) expression and activity, were observed in the diabetic and synchronous rats.
RESULTSThe results showed that CD147 located on sarcolemma of cardiomyocytes. The myocardial CD147 expression and glycosylation were significantly increased in the diabetic rats as compared with the control. Expression of MMP-2 protein, MMP-2 and MMP-9 activity were also increased in left ventricular myocardium in the diabetic rats. Tamoxifen only inhibited the enhanced expression of myocardial CD147 in the diabetic rats, but not in synchronous control rats. Tamoxifen inhibited glycosylation of myocardial CD147 in both diabetic and control rats. The inhibition of tamoxifen on CD147 glycosylation was stronger than on the expression in the myocardium. The extent of myocardial CD147glycosylation was positively related toMMP-2 and MMP-9 activity. Tamoxifen induced an inhibition of myocardial MMP-2 and MMP-9 activity in the control and diabetic rats.
CONCLUSIONThese results indicate that myocardial CD147 expression, especially the extent of glycosylation, regulates MMP-2 and MMP-9 activity, then accelerates cardiac pathological remodeling inducing diabetic cardiomyopathy. Tamoxifen inhibits myocardial CD147 glycosylation and further depress the activity of MMPs. Therefore, tamoxifen may protect the diabetic rats against diabetic myocardium.

OBJECTIVETo evaluate the effect of vitamin D level on early-onset sepsis (EOS) in neonates.
METHODSSeventy-eight full-term neonates with EOS were used as the research group (EOS group). sixty healthy full-term neonates without clinical and/or laboratory features related to infections were used as the control group. Blood samples of the neonates and their mothers in both groups were collected within 72 hours of delivery to determine 25-hydroxyvitamin D(25-OHD) levels. The rate of vitamin D deficiency in the neonates and the level of 25-OHD supplemented to their mothers during pregnancy were compared between the two groups.
RESULTSThere was a significant positive correlation between the serum level of 25-OHD of the mothers and that of the neonates in both groups (EOS group: r=0.797, P<0.01; control group: r=0.929, P<0.01). The neonates and their mothers in the EOS group had significantly lower 25-OHD levels than those in the control group (P<0.01). The rate of vitamin D deficiency among the neonates in the EOS group was significantly higher than that of the control group (P<0.01). The level of vitamin D supplemented to the mothers during the last 3 months of pregnancy in the EOS group was significantly lower than that in the control group (P<0.01).
CONCLUSIONSLow serum level of 25-OHD is associated with the development of early-onset sepsis in full-term neonates.

Objective To study the infection status of HIV-1 among blood recipients from 1994 to 1998 in certain areas of Hebei province. Methods A general investigation was set up among all the people in 15 townships of certain areas from November 2003 to February 2005. An epidemiological investigation was conducted among people who had received blood from donors, during 1994 and 1998. Blood samples were collected. ELISA was used in preliminary screening and Western-blot (WB) was used among people who showed a positive result in the preliminary screening. Results The infection rate of HIV-1 after blood receipt was 15.54% (92/592) , and the infected persons were all appeared in five medical centers of 6 townships which located at the west part of the area. HIV-1 infection happened over the years, and reaching the zenith in the year 1995. Most of the infected persons were young women. Procreation was the main cause of blood transfusion for women and trauma was for men. Conclusion A typical HIV outbreak happened in certain areas after blood transfusion in Hebei.

PURPOSE: Although the interferon α (IFNα) signaling and the paired-like homeodomain transcription factor 2 (PITX2) have both been implicated in the progression of breast cancer (BCa), it remains obscure whether these two pathways act in a coordinated manner. We therefore aimed to elucidate the expression and function of PITX2 during the pathogenesis of endocrine resistance in BCa. MATERIALS AND METHODS: PITX2 expression was assessed in BCa tissues using quantitative reverse transcription polymerase chain reaction (RT-qPCR) and immunohistochemistry and in experimentally induced letrozole-resistant BCa cells using RT-qPCR and immunoblotting. Effects of PITX2 deregulation on BCa progression was determined by assessing MTT, apoptosis and xenograft model. Finally, using multiple assays, the transcriptional regulation of interferon-inducible transmembrane protein 1 (IFITM1) by PITX2 was studied at both molecular and functional levels. RESULTS: PITX2 expression was induced in letrozole-resistant BCa tissues and cells, and PITX2 induction by IFNα signaling powerfully protected BCa cells against letrozole insult and potentiated letrozole-resistance. Mechanistically, PITX2 enhanced IFNα-induced AKT activation by transactivating the transcription of IFITM1, thus rendering BCa cells unresponsive to letrozoleelicited cell death. Additionally, ablation of IFITM1 expression using siRNA substantially abolished IFNα-elicited AKT phosphorylation, even in the presence of PITX2 overexpression, thus sensitizing BCa cells to letrozole treatment. CONCLUSION: These results demonstrate that constitutive upregulation of PITX2/IFITM1 cascade is an intrinsic adaptive mechanism during the pathogenesis of letrozole-resistance, and modulation of PITX2/IFITM1 level using different genetic and pharmacological means would thus have a novel therapeutic potential against letrozole resistance in BCa.

OBJECTIVE:
To explore the value of galactose-deficient IgA1 (Gd-IgA1) in the early diagnosis of Henoch-Schönlein purpura nephritis (HSPN) in children.
METHODS:
A total of 67 hospitalized children who were definitely diagnosed with HSPN between January and April 2018 and 58 hospitalized children with Henoch-Schönlein purpura (HSP) were enrolled in the study. Twenty children undergoing routine physical examinations served as controls. The levels of serum and urine Gd-IgA1 were determined using ELISA. The receiver operating characteristic curve was used to analyze the value of serum Gd-IgA1 and urine Gd-IgA1/urine creatinine ratio in the diagnosis of HSPN.
RESULTS:
The level of serum Gd-IgA1 and urine Gd-IgA1/urine creatinine ratio in children with HSP or HSPN were significantly higher than those in healthy control group (P<0.01), with a significantly greater increase observed in children with HSPN (P<0.01). Serum Gd-IgA1 ≥1 485.57 U/mL and/or urine Gd-IgA1/urine creatinine ratio ≥105.74 were of favorable value in the diagnosis of HSPN. During the six-month follow-up of the 49 children with HSP, the incidence of HSPN was 47% (23/49), which included a 100% incidence in children with serum Gd-IgA1 ≥1 485.57 U/mL and a 73% incidence in children with urine Gd-IgA1/urine creatinine ratio ≥105.74.
CONCLUSIONS
Serum and urine Gd-IgA1 is of favorable clinical value in the early diagnosis of HSPN.
