ABSTRACT

Cancer development is a complicated process controlled by the interplay of multiple signaling pathways and restrained by oxygen and nutrient accessibility in the tumor microenvironment. High plasticity in using diverse nutrients to adapt to metabolic stress is one of the hallmarks of cancer cells. To respond to nutrient stress and to meet the requirements for rapid cell proliferation, cancer cells reprogram metabolic pathways to take up more glucose and coordinate the production of energy and intermediates for biosynthesis. Such actions involve gene expression and activity regulation by the moonlighting function of oncoproteins and metabolic enzymes. The signal - moonlighting protein - metabolism axis facilitates the adaptation of tumor cells under varying environment conditions and can be therapeutically targeted for cancer treatment.

ABSTRACT

Objective:To explore the relationship between different serum albumin and lymphocyte levels in patients with 2019-novel coronavirus (2019-nCoV) pneumonia (COVID-19).Methods:A retrospective study was performed to identify the characteristics of the clinical data of 205 COVID-19 patients who were hospitalized in the Happy Street of Hanchuan People's Hospital, Xiaogan, Hubei Province from January 24 to February 12, 2020, including their general information, serum albumin (ALB) levels, lymphocyte counts (LYM), percentage of lymphocytes (LYM%) and other laboratory parameter levels. Low ALB group and normal ALB group were demarcated by the concentration of 35 g/L, further to identify the differences of LYM and LYM% levels and the incidence of LYM and LYM% decline at different ALB levels between groups,as well as the correlation between ALB and LYM, LYM% levels in hypoalbuminemia conditions .Results:17.5% of COVID-19 patients were associated with hypoalbuminemia. The levels of LYM and LYM% in the low ALB group were significantly lower than those in the normal ALB group ( P <0.001). The incidence of LYM and LYM% decline in the low ALB group was significantly higher than those in the normal ALB group ( P <0.001). The levels of LYM and LYM% in the low ALB group were significantly positively correlated with serum ALB concentrations ( P <0.05). Conclusions:The decrease of lymphocyte levels in COVID-19 patients may be correlated to hypoalbuminemia. COVID-19 patients complicated by hypoalbuminemia should be actively intervened to maintain serum albumin in the normal range.

ABSTRACT

In this study, we aimed to analyze the anti-cancer effects of β-elemene combined with paclitaxel for ovarian cancer. RT-qPCR, MTT assay, western blot, flow cytometry, and immunohistochemistry were used to analyze in vitro and in vivo anti-cancer effects of combined treatment of β-elemene and paclitaxel. The in vitro results showed that β-elemene+paclitaxel treatment markedly inhibited ovarian cancer cell growth, migration, and invasion compared to either paclitaxel or β-elemene treatment alone. Results demonstrated that β-elemene+paclitaxel induced apoptosis of SKOV3 cells, down-regulated anti-apoptotic Bcl-2 and Bcl-xl gene expression and up-regulated pro-apoptotic P53 and Apaf1 gene expression in SKOV3 cells. Administration of β-elemene+paclitaxel arrested SKOV3 cell cycle at S phase and down-regulated CDK1, cyclin-B1, and P27 gene expression and apoptotic-related resistant gene expression of MDR1, LRP, and TS in SKOV3 cells. In vivo experiments showed that treatment with β-elemene+paclitaxel significantly inhibited ovarian tumor growth and prolonged the overall survival of SKOV3-bearing mice. In addition, the treatment inhibited phosphorylated STAT3 and NF-κB expression in vitro and in vivo. Furthermore, it inhibited migration and invasion through down-regulation of the STAT-NF-κB signaling pathway in SKOV3 cells. In conclusion, the data suggested that β-elemene+paclitaxel can inhibit ovarian cancer growth via down-regulation of the STAT3-NF-κB signaling pathway, which may be a potential therapeutic strategy for ovarian cancer therapy.

ABSTRACT

OBJECTIVE To drew the map of distribution of concealed sites in epistaxis and optimize the mode of diagnosis and treatment. METHODS We have searched 117 references on intractable/refractory/latent epistaxis treated under nasal endoscopy in the last decade, including 11 708 cases with epistaxis. There were total 11 860 cases in this study plus 152 cases in our hospital. We summed up the experiences of the optimized treatment mode performed on concealed epistaxis, which was searching the accurate bleeding areas by nasal endoscopy and performing minimally invasive radiofrequency treatment without nasal packing. RESULTS We had found that the offending arteries about epistaxis are mainly sphenopalatine artery and anterior or posterior ethmoid artery. The frequency of bleeding areas came as follows: the vault of inferior nasal meatus in 3783 cases(31.90%), the olfactory sulcus of middle turbinate in 3522 cases(29.70%), the posterior regions of middle meatus in 1349 cases(11.37%), the regions of deviation of nasal septum in 1065 cases(8.98%), the foremost regions of nasal cavity in 738 cases(6.22%), and the others or uncertain in 1403 cases(11.83%). Finally, we drew a concise map of distribution about epistaxis on the basis of the concealed bleeding areas and offending vessels. 151 of 152 patients(99.34%) could find out the bleeding sites accurately and stop the bleeding through minimally invasive radiofrequency ablation. CONCLUSION We drew a map of distribution about epistaxis in concealed areas so that it is convenient for us to seek out the bleeding sites. Rational use of nasal endoscopy to explore the sites of intractable epistaxis and minimally invasive radiofrequency are optimized mode of treatment.

ABSTRACT

Objective To observe the clinical efficacy of hydroxyfasudil in senile heart failure caused by coronary heart disease (CHD). Methods 110 Patients with heart failure caused by CHD were randomly divided into two groups. 55 patients in control group were given conventional treatment, whereas the remaining patients were assigned into hydroxyfasudil group in the base of conventional treatment. After 6 months, we observed and compared the changes in cardiac function of the two groups. Results The effective rate of treatment group was 96.36% and the control group was 85.45%. There was statistical difference between the two groups (P < 0.05). Then we compared the degree of improvement of left ventricular diastolic function using ultrasonic cardiogram and Tei index. Left ventricular ejection fraction of treatment group improved significantly but biochemical indicators of two groups had no statistical difference. Conclusion In patients with heart failure caused by CHD, supplementation of hydroxyfasudil based on conventional therapy could improve diastolic function , potentiate left ventricular remodeling and enhance the life quality. Furthermore, it′s more sensitivity and reasonable to assess cardiac function using Tei index as compared with using ultrasonic cardiogram.

ABSTRACT

The growth inhibition and pro-apoptosis effects of dracorhodin perchlorate on human prostate cancer PC-3 cell line were examined. After administration of 10-80 μmol/L dracorhodin perchlorate for 12-48 h, cell viability of PC-3 cells was measured by MTT colorimetry. Cell proliferation ability was detected by colony formation assay. Cellular apoptosis was inspected by acridine orange-ethidium bromide fluorescent staining, Hoechst 33258 fluorescent staining, and flow cytometry (FCM) with annexin V-FITC/propidium iodide dual staining. The results showed that dracorhodin perchlorate inhibited the growth of PC-3 in a dose- and time-dependent manner. IC50 of dracorhodin perchlorate on PC-3 cells at 24 h was 40.18 μmol/L. Cell clone formation rate was decreased by 86% after treatment with 20 μmol/L of dracorhodin perchlorate. Some cells presented the characteristic apoptotic changes. The cellular apoptotic rates induced by 10-40 μmol/L dracorhodin perchlorate for 24 h were 8.43% to 47.71% respectively. It was concluded that dracorhodin perchlorate significantly inhibited the growth of PC-3 cells by suppressing proliferation and inducing apoptosis of the cells.
