Incremental value of epicardial fat volume on predicting obstructive coronary artery disease with myocardial ischemia / 中华心血管病杂志

Objective: This study aimed to investigate the association between epicardial fat volume (EFV) and obstructive coronary artery disease (CAD) with myocardial ischemia, and evaluate the incremental value of EFV on top of traditional risk factors and coronary artery calcium (CAC) in predicting obstructive CAD with myocardial ischemia. Methods: This study was a retrospective cross-sectional study. Patients with suspected CAD who underwent coronary angiography (CAG) and single photon emission computerized tomography-myocardial perfusion imaging (SPECT-MPI) at the Third Affiliated Hospital of Soochow University from March 2018 to November 2019 were consecutively enrolled. EFV and CAC were measured by non-contrast chest computed tomography (CT) scan. Obstructive CAD was defined as coronary artery stenosis≥50% in at least one of the major epicardial coronary arteries, and myocardial ischemia was defined as reversible perfusion defects in stress and rest MPI. Obstructive CAD with myocardial ischemia was defined in patients with coronary stenosis severity≥50% and reversible perfusion defects in the corresponding areas of SPECT-MPI. Patients with myocardial ischemia bot without obstructive CAD were defined as none-obstructive CAD with myocardial ischemia group. We collected and compared the general clinical data, CAC and EFV between the two groups. Multivariable logistic regression analysis was performed to identify the relationship between EFV and obstructive CAD with myocardial ischemia. ROC curves were performed to determine whether addition of EFV improved predictive value beyond traditional risk factors and CAC for obstructive CAD with myocardial ischemia. Results: Among the 164 patients with suspected CAD, 111 patients were males, and average age was (61.4±9.9) years old. 62 (37.8%) patients were included into the obstructive CAD with myocardial ischemia group. 102 (62.2%) patients were included into the none-obstructive CAD with myocardial ischemia group. EFV was significantly higher in obstructive CAD with myocardial ischemia group than in none-obstructive CAD with myocardial ischemia group ((135.63±33.29)cm3 and (105.18±31.16)cm3, P<0.01). Univariate regression analysis showed the risk of obstructive CAD with myocardial ischemia increased by 1.96 times for each SD increase in EFV(OR 2.96; 95%CI, 1.89-4.62; P<0.01). After adjustment for traditional risk factors and CAC, EFV remained as an independent predictor for obstructive CAD with myocardial ischemia (OR, 4.48, 95%CI, 2.17-9.23; P<0.01). Addition of EFV to CAC and traditional risk factors was related to larger AUC for predicting obstructive CAD with myocardial ischemia (0.90 vs. 0.85, P=0.04, 95%CI: 0.85-0.95) and the global chi-square increased by 21.81 (P<0.05). Conclusions: EFV is an independent predictor for obstructive CAD with myocardial ischemia. Addition of EFV to traditional risk factors and CAC has incremental value for predicting obstructive CAD with myocardial ischemia in this patient cohort.

OBJECTIVE@#To explore the effect of "Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion on the ovarian function in the rats with primary ovarian insufficiency (POI) and the potential effect mechanism based on the Fas/FADD/Caspase-8 of death receptor pathway.@*METHODS@#Forty-eight female SD rats were randomly divided into a blank group, a model group, a medication group and an acupuncture group, with 12 rats in each group. Except in the blank group, the rats in the other groups were intraperitoneally injected with cyclophosphamide to establish the POI model. In the acupuncture group, after successful modeling, the intervention was given with "Zhibian" (BL 54)-to- "Shuidao" (ST 28) needle insertion, once daily, 30 min in each intervention; and the duration of intervention was 4 weeks. In the medication group, estradiol valerate tablets were administered intragastrically, 0.09 mg•kg-1•d-1, for 4 weeks. The general situation and the estrous cycle of the rats were compared among groups. Using ELISA, the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the serum were detected. HE staining was adopted to observe the morphological changes of ovarian tissue of rats. The protein expression of Fas, FADD and Caspase-8 in ovarian tissue was detected with immunohistochemistry and Western blot.@*RESULTS@#After modeling, except the rats of the blank group, the rats of the other groups had dry fur, lost hair, low spirits, reduced food intake, increased urination and loose stool. After intervention, the stool became regular gradually in the acupuncture group and the medication group. The percentage of estrous cycle disturbance was increased in the rats of the model group when compared with the blank group (P<0.01); in comparison with the model group, the percentages of estrous cycle disturbance were reduced in the acupuncture group and the medication group after intervention (P<0.01). When compared with the blank group, the body mass and E2 content in the serum were lower (P<0.01), the levels of FSH and LH in the serum and the protein expression levels of Fas, FADD and Caspase-8 were increased (P<0.01) in the model group. Compared with the model group, the body mass and E2 contents in the serum were higher (P<0.01), the levels of FSH and LH in the serum and the protein expression levels of Fas, FADD and Caspase-8 were reduced (P<0.01) in the acupuncture group and the medication group.@*CONCLUSION@#"Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion can effectively improve the ovarian function of POI rats, and its effect mechanism may be related to regulating the serum sex hormone levels, reducing the expression of Fas, FADD and Caspase-8 in ovarian tissue and retarding apoptosis of ovarian cells.

Effect of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on the expression of apoptosis-related factors in rats with premature ovarian insufficiency based on oxidative stress / 中国针灸

OBJECTIVE@#To explore the possible mechanism of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on premature ovarian insufficiency (POI) from the perspective of oxidative stress.@*METHODS@#Sixty female SD rats were randomly divided into a blank group, a model group, a sham acupuncture group, a medication group, and an acupuncture group, 12 rats in each group. Except the blank group, the rats in the remaining groups were intraperitoneally injected with cyclophosphamide to establish the POI model. After the model was successfully established, the rats in the acupuncture group were treated with acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28), with a depth of about 12 mm, and the needle was retained for 30 min; the acupuncture was given once a day, for a total of 4 weeks. The rats in the sham acupuncture group were treated with blunt-head needle to tap the skin surface of "Zhibian" (BL 54), without penetrating the skin, once a day for 4 weeks. The rats in the medication group were treated with estradiol valerate by gastric gavage for 4 weeks. After the intervention, the level of reactive oxygen species (ROS) in the ovarian tissue was detected by fluorescence probe; the expression of c-Jun N-terminal kinase (JNK), forkhead box O1 (FoxO1), tumor suppressor gene protein 53 (p53) and p53 up-regulated modulator of apoptosis (Puma) mRNA and protein in ovarian tissue were detected by real-time fluorescence quantitative PCR and Western blot.@*RESULTS@#Compared with the blank group, the level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the model group were increased (P<0.01). Compared with the model group, the level of ROS and the expression of p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the sham acupuncture group were slightly reduced, but the difference was not statistically significant (P>0.05). The level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the acupuncture group and the medication group were reduced (P<0.01).@*CONCLUSION@#Acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) could improve the level of oxidative stress, down-regulate the expression of apoptosis-related factors JNK, FoxO1, p53 and Puma induced by oxidative stress, and inhibit the premature failure of ovarian reserve function caused by apoptosis of ovarian granulosa cells in POI rats.

Its mechanism may be related to up-regulating the protein and mRNA expression of MR and GR in the hippocampus, and then affecting the expression of serum cortisol and 5-HT.

Silybin alleviates hepatic lipid accumulation in methionine-choline deficient diet-induced nonalcoholic fatty liver disease in mice via peroxisome proliferator-activated receptor α / 中国天然药物

Nonalcoholic fatty liver disease (NAFLD) is regarded as the most common liver disease with no approved therapeutic drug currently. Silymarin, an extract from the seeds of Silybum marianum, has been used for centuries for the treatment of various liver diseases. Although the hepatoprotective effect of silybin against NAFLD is widely accepted, the underlying mechanism and therapeutic target remain unclear. In this study, NAFLD mice caused by methionine-choline deficient (MCD) diet were orally administrated with silybin to explore the possible mechanism and target. To clarify the contribution of peroxisome proliferator-activated receptor α (PPARα), PPARα antagonist GW6471 was co-administrated with silybin to NAFLD mice. Since silybin was proven as a PPARα partial agonist, the combined effect of silybin with PPARα agonist, fenofibrate, was then evaluated in NAFLD mice. Serum and liver samples were collected to analyze the pharmacological efficacy and expression of PPARα and its targets. As expected, silybin significantly protected mice from MCD-induced NAFLD. Furthermore, silybin reduced lipid accumulation via activating PPARα, inducing the expression of liver cytosolic fatty acid-binding protein, carnitine palmitoyltransferase (Cpt)-1a, Cpt-2, medium chain acyl-CoA dehydrogenase and stearoyl-CoA desaturase-1, and suppressing fatty acid synthase and acetyl-CoA carboxylase α. GW6471 abolished the effect of silybin on PPARα signal and hepatoprotective effect against NAFLD. Moreover, as a partial agonist for PPARα, silybin impaired the powerful lipid-lowering effect of fenofibrate when used together. Taken together, silybin protected mice against NAFLD via activating PPARα to diminish lipid accumulation and it is not suggested to simultaneously take silybin and classical PPARα agonists for NAFLD therapy.

Association between Recurrence and Survival Rates According to the Location of Gastric Gastrointestinal Stromal Tumor

BACKGROUND/AIMS: This study aimed to evaluate the clinicopathological parameters of gastric gastrointestinal stromal tumors (GISTs) and to investigate the effect of tumor site on clinical outcomes. MATERIALS AND METHODS: Patients treated for a surgically confirmed gastric GIST were retrospectively evaluated between January 2001 and June 2016. The risk level was determined on the basis of the tumor size and number of mitoses. The risk level, recurrence rate, and survival rates were evaluated on the basis of the site of the gastric GISTs. RESULTS: The 97 patients identified included 42 men and 55 women. The median follow-up period was 36 months (range: 12~72 years). Of the 97 patients, 57 (58.7%) and 40 (41.3%) patients had proximally and distally located gastric GISTs, respectively. The high- and low-risk groups had higher proportions of proximally and distally located tumors, respectively (P=0.033). The recurrence rates of proximal and distal GISTs were 8.8%, and 2.5%, respectively (P=0.307). The overall survival rate was not associated with the site of the gastric GISTs (P=0.549). CONCLUSIONS: No relevant associations were found among recurrence, overall survival, and gastric GIST location.

Clinical features and prognosis of acute monocytic leukemia with abnormality of chromosome 8 / 中国实用内科杂志

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with acute monocytic leukemia(AML-M5)with abnormality of chromosome 8.METHODS: The clinical features of 143 patients with AML-M5 were analyzed retrospectively,and the prognosis factors were analyzed.RESULTS: Out of 143 AML-M5 newly diagnosed patients,37 cases with chromosome 8 aberrations including t(8;21)accounting for 6.99%(10/143),trisomy 8 16.08%(23/143),and other 8 aberrations 2.80%(4/143);73 cases had normal karyotype,and 33 cases possessed non chromosome 8 abnormality.Statistically significant differences did not exist among age,sex,hemogram and bone marrow blasts(P>0.05).However,with chromosome 8 abnormality were predisposed to lower initial white blood cell count(P<0.05).Among 131 patients of receiving chemotherapy,the remission rate after the first course of inducible chemotherapy was 63.36%(83/131)and the one-year survival rate was 61.1%.Analysis of prognostic factors showed that age,the remission after the first induction of chemotherapy(complete remission or no remission),trisomy 8 chromosomal karyotype and treatment regimen(chemotherapy alone or plus hematopoietic stem cell transplantation) had effects on overall survival(P<0.05).Multivariate analysis revealed two independent risk factors:age≥60 years(P<0.05,HR=2.134,95% CI 1.204～3.784)and the complete remission after the first induction of chemotherapy(P<0.05,HR=0.408,95% CI 0.227～0.733).CONCLUSION: Chromosome 8 is easily involved in AML-M5.The patients with involvement of this aberration have lower initial white blood cell count and a poor prognosis.Patients after complete remission have hematopoietic stem cell transplantation is beneficial to prolong survival.

FGFR1 is an independent prognostic factor and can be regulated by miR-497 in gastric cancer progression

Fibroblast growth factor receptor 1 (FGFR1) has been reported in gastric cancer to be a prognostic factor. However, miR-497-targeted FGFR1 has not been explored in the carcinogenesis of gastric cancer. The present study intended to revalidate the prognostic significance of FGFR1 in patients with gastric cancer, and the mechanism of miR-497-regulated FGFR1 was investigated in gastric cancer cell proliferation and apoptosis. The messenger RNA (mRNA) and protein levels were assayed by RT-qPCR and western blotting, respectively. The targeted genes were predicted by a bioinformatics algorithm and confirmed by a dual luciferase reporter assay. Cell proliferation was analyzed by CCK-8 assay. Annexin V-FITC/PI staining was used to evaluate the apoptosis in AGS and SGC-7901 cells. FGFR1 was frequently up-regulated in gastric cancer tissues and associated with poor overall survival in patients with gastric cancer. Interestingly, FGFR1 loss-of-function resulted in a significant growth inhibition and apoptosis in AGS and SGC-7901 cells. In addition, we found that miR-497 was inhibited in gastric cancer tissues and cell lines, while overexpression of miR-497 could suppress proliferation and induce apoptosis in AGS and SGC-7901 cells. Importantly, bioinformatics analysis and experimental data suggested that FGFR1 was a direct target of miR-497, which could inhibit FGFR1 expression when transfected with miR-497 mimics. Furthermore, we found that overexpression of FGFR1 reversed the growth inhibition and apoptosis of miR-497 mimics in AGS and SGC-7901 cells. These findings suggested that overexpression of miR-497 inhibited proliferation and induced apoptosis in gastric cancer through the suppression of FGFR1.

Factors Affecting Cognitive Function in Patients with Stomach Cancer

PURPOSE: This study aimed to identify factors affecting cognitive function in stomach cancer patients. METHODS: This was a cross-sectional study designed to obtain data from stomach cancer patients. The Global Assessment of Recent Stress, Hospital Anxiety-Depression Scale, Distress Thermometer, Korean version of the Montreal Cognitive Assessment, and electronic medical records were used to assess stress, anxiety, depression, psychological distress, and cognitive function, respectively. RESULTS: Among 182 total participants, there were statistically significant differences in sex between the group of patients who received chemotherapy and those who did not (χ2=5.32, p=.029). There were statistically significant differences in stress and cognitive function between the two groups. The factors affecting cognitive function in stomach cancer patients included distress, stress, anxiety, and depression. CONCLUSION: Cognitive function should be examined with consideration of the psychological distress, stress, anxiety, and depression in patients with stomach cancer. Moreover, an improved program to manage cognitive function is needed, which includes mediation between psychological and physiological factors including stress, anxiety, and cognitive level.

Effects of ZNF331 overexpression on human colon cancer cell proliferation and apoptosis / 军事医学

Objective To investigate the effects of ZNF331 overexpression on proliferation and apoptosis of human colon cancer cell HCT116, and the relevant apoptotic mechanism.Methods The lentivirus vector of overexpressed ZNF331,Flag-pLV-Neo-ZNF331,was constructed and packaged.HCT116/p53 +/+(wild type p53)and HCT116/p53 -/-(deficient p53)cells were infected.Clones with ZNF331 overexpression were identified by Western blotting.Cell proliferation assay,colony formation assay and flow cytometry analysis were used to examine the effects of ZNF 331 on cell proliferation and apoptosis.Immunoprecipitation,luciferase reporter gene assay and real-time PCR were performed to detect interactions between ZNF331 and p53, p53 transcriptional activity and the expression of p 53 apoptotic target genes, respectively.Results The lentivirus vector of overexpressed ZNF 331 was successfully generated.Stable clones of ZNF331 overexpression were established.ZNF331 showed no significant effect on cell proliferation of HCT 116/p53 +/+, but inhibited cell proliferation of HCT116/p53 -/-(P<0.01).ZNF331 could interact with p53,dose-dependently inhibit the transcriptional activity of p53 and downregulate the mRNA levels of pro-apoptotic p53 target genes, Puma and p53AIP1 (P<0.05).ZNF331 could suppress p53-induced apoptosis(P <0.01).Conclusion The influence of ZNF331 overexpression on colon cancer cell proliferation is dependent on p 53 status.ZNF331 overexpression can suppress colon cancer cell apoptosis by interacting with p 53 and inhibiting the transcriptional activity of p 53.

Recent progress of inhibitors targeting HIV-1 NCp7 / 药学学报

The acquired immunodeficiency syndrome (AIDS) is a serious infectious disease infected by human immunodeficiency virus type 1 (HIV-1). HIV-1 nucleocapsid protein 7 (HIV-1 NCp7) plays an important role in the progress of virus reverse transcription and integration. Thus, the central role and conservative nature of the NCp7 protein make it an attractive target for development of novel anti-HIV agents. This review summarizes the research progress of HIV-1 NCp7 inhibitors in the past decade.
