The degree of hemodynamic support by vasoactive drugs in critically ill patients is often considered one of the markers of disease severity. The sequential organ failure assessment (SOFA), European system for cardiac operative risk evaluation Ⅱ (EuroScoreⅡ), and other scores only roughly quantify the drug support of cardiovascular system. When patients need large doses of vasoactive drugs, the mortality increases accordingly. The vasoactive-inotropic score (VIS) objectively quantifies the degree of cardiovascular support using a simple formula that standardizes the dose of different agents, and it is recommended as a simple, effective, and accurate prognostic indicator. In recent years, there are more and more clinical applications and related studies at home and abroad. This paper reviews the application and progress of VIS score in critically ill patients, providing help for doctors to judge the condition and prognosis of patients and guiding the decision-making of diagnosis and treatment.

Objective:To analyze the status and influencing factors of early out of bed activity in patients after coronary artery bypass grafting.Methods:Using the convenient sampling method, patients who underwent coronary artery bypass grafting in Affiliated Hospital of Jining Medical University from January 2018 to December 2020 were selected as the research objects. The general situation questionnaire, the Chinese version of Brief Disease Cognition Questionnaire, Muscle Strength Rating Scale and Visual Analog Scale were used to investigate them. Binomial Logistic regression was used to analyze the influencing factors of early out of bed activity after coronary artery bypass grafting.Results:A total of 100 questionnaires were distributed in this study and 100 were recovered. The effective recovery rate of the questionnaire was 100%. 38% (38/100) of patients with coronary artery bypass grafting performed early out of bed activity within 72 hours after surgery. Binomial Logistic regression analysis showed that vascular bridge selection, postoperative pain, lower limb incision blister, lower limb muscle strength rating and disease awareness were the influencing factors of early out of bed activity after coronary artery bypass grafting ( P<0.05) . Conclusions:Vascular bridge selection, postoperative pain, lower limb incision blister, lower limb muscle strength rating and disease awareness were the influencing factors of early out of bed activity after coronary artery bypass grafting

Objective To explore the role of cerebrospinal fluid chimerism in central nervous relapse surveillance for patients of acute leukemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods The follow-up data were retrospectively collected and analyzed in 104 patients with acute leukemia after allo-HSCT.Comparisons were made between patients with complete chimerism and mixed chimerism in cerebrospinal fluid.The role of recipient DNA percentage and its changing trend in predicting central nervous relapse were also explored.Analysis was conducted for determining the risk factors of central nervous relapse.And the effectiveness of prophylaxis with intrathecal injection was also examined.Results The incidence of relapse was higher in patients with mixed chimerism (P＜0.001),high percentage of recipient DNA (P＜0.05) and higher mixed chimerism (P＜0.001).Hyperleukocytosis at an initial diagnosis was a risk factor of central nervous relapse.Whether or not intrathecal injection prophylaxis was applied showed no significant difference in relapsing rate.Conclusions Monitoring cerebrospinal fluid chimerism can effectively help predict central nervous relapse among patients of acute leukemia after allo-HSCT.Yet intrathecal injection prophylaxis failed to benefit recipients.

Rapid eye movement sleep behavior disorder (RBD) is currently considered as a prodromal stage of alphasynucleinopathies neurodegeneration. The update data suggested that over 80% patients with idiopathic RBD eventually developed neurodegenerative disease after a mean of 14 years interval from the onset of RBD. A series of potential biomarkers have been identified to predict the development of neurodegeneration in idiopathic RBD, including olfactory loss, color vision deficit, depression, mild cognitive impairment, excessive daytime sleepiness, dopamine dysfunction, and tonic electromyographic activity. Early recognition of the predictive markers of neurodegeneration in idiopathic RBD is essential for development of intervention or prevention strategies at the presymptomatic stage. Nonetheless, the current literature is lacking biomarkers that might reflect the alpha-synuclein neuropathology at the earliest stages. Future studies with large samples and systematic follow-up are needed to confirm more potential markers of neurodegeneration at its early stages.

OBJECTIVE: To study the effect of miR-342-3p on the chemotherapy sensitivity in triple-negative breast cancer (TNBC). METHODS: Tissue samples were collected from January 2011 to August 2013 samples in Jiangsu Cancer Hospital from a total of 32 triple-negative breast cancer patients with preoperative chemotherapy, with 5 cases of complete response (CR) and 27 cases of partial response (PR). We detected miR-342-3p expression of TNBC with RT-PCR. We transfected has-miR-342-3p mimic and inhibitor into breast cancer cell lines MDA-MB-231 by lipofection transfection and set up negative control mim-NC and inhi-NC. Group of mimic, mim-NC, inhibitor and inhi-NC were cultivated with 2 μmol /L paclitaxel, cisplatin or 4 μmol/L doxorubicin for 48 h. The cell growth rates were measured by CCK8 reagent kit, and the cell apoptosis rate by flow cytometry. RESULTS: The expressions of miRNA-342-3p in TNBC tissue of CR were higher than those of PR. The cell growth rates of mimic were lower and cell apoptosis rates were higher than those of min- NC after cultivating with paclitaxel or cisplatin for 48 h, with significant difference (P<0.05). The cell growth rates of inhibitor were higher and cell apoptosis rates lower than those of inhi-NC after cultivating with paclitaxel or cisplatin 48 h, with significant difference (P<0.05). The cell growth and cell apoptosis rates of mimic and inhibitor had no difference with those of mim-NC and inhi- NC after cultivating with doxorubicin 48 h (P>0.05). CONCLUSION TNBC with high expression of miR-342-3p are more sensitive to chemotherapy. miRNA-342-3p may regulate the sensitivity of breast cancer cell line MDA-MB-231 to chemotherapy drugs paclitaxel and cisplatin, but can not affect the chemotherapy sensitivity of doxorubicin.

This study was conducted to investigate the anti-tumor efficacy of nanosecond pulsed electric fields (nsPEFs) on the mouse with A375-GFP melanoma xenograft in vivo. In vivo fluorescence image analysis system was used in this study to evaluate the effects of nsPEFs on human melanoma A375 cell xenograft. On the Day 90 af ter pulse delivery, the skin that had contained A375 cell xenograft was surgically excised and pathologically evalua ted. The changes of scar were recorded by digital camera. The experiment revealed that significant changes in fluorescence value trend and amplitude were found in the treated group from those in the control group. The fluorescence of tumor in the treated group decreased mostly 48 h after the treatment and completely disappeared 10 d after the treatment, while that in control group was increased gradually. Surgical excision of the area confirmed a complete pathologic response. Within a few days after the nsPEFs treatment, a hard scab formed at the treatment region. The scab fell off by the end of the second week. As time went on, the scar gradually became faded and all xenograft tumors were disappeared without recurrence. From the experiment, we learn that nsPEFs can bring good therapeutic effect. It may provide a new approach for the clinical treatment of superficial tumors.

Objective To investigate the relationship between various stages of chronic hepatitis B virus (HBV) infection and lipid metabolism and its influencing factors.Methods Seventy-two cases of chronic hepatitis B (CHB),40 cases of liver cirrhosis and 17 cases of hepatocellular carcinoma (HCC) were enrolled.One-way ANOVA analyses were used to compare age,gender,liver function,lipid metabolism,and HBV DNA levels of each group.Pearson correlation analysis was used to study the correlation between HBV DNA and lipid metabolism.Binary Logistic regression analyses were performed to explore the risk factors of cirrhosis and HCC in patients with CHB.Results Differences of age,alanine aminotransferase (ALT),albumin (Alb),triglyceride (TG),and cholesterol(CHO) among the three groups (CHB group,cirrhosis group and HCC group) were statistically significant (all P＜0.05).TG levels in cirrhosis and HCC groups were (-0.061± 0.234)lg mmol/L and (-0.061±0.253) lg mmol/L,respectively,which were both significantly lower than that of the CHB group (0.116±0.182) lg mmol/L (F=11.466,P=0.000).CHO level in cirrhosis group was (0.460±0.333) lg mmol/L,which was lower than that in CHB group (0.586±0.101) lg mmol/L (F=4.892,P=0.009).The HBV DNA levels inversely correlated with TG and CHO levels in CHB group (r=-0.266,P=0.024; r=-0.309,P=0.008,respectively).The HBV DNA levels of cirrhosis and HCC patients positively correlated with ALT levels (r=0.355,P =0.007).Old age (OR=1.096,95％CI:1.025-1.172),low Alb (OR=0.000,95％CI:0.000-0.000),and low levels of ALT (OR=0.128,95％CI:0.026-0.641) were risk factors for development of cirrhosis and HCC in CHB patients (all P＜0.05).Conclusions With the progression of liver injuries,TG and CHO levels are reduced.Further studies of correlation between risk factors for the development of cirrhosis and HCC and lipid metabolism in CHB patients are needed.

This paper is to investigate the apoptosis effect of ovarian cancer SKOV3 cells induced by nanosecond plused electric fileds (nsPEFs) and to study its influence on Fas-mediated apoptosis. SKOV3 cell were exposed to the 45kV/cm of field intensity, 30 pulses, and 50ns, 100ns, and 200ns of pulse width, respectively. Flow cytometry were used to assay apoptosis. Agarose gel electrophoresis was used to detect DNA ladder. Real time PCR (RT-PCR) and Western blot analysis were used to measure the expression level of Fas, FasL, caspase-8 and Bid. Flow cytometry results revealed that the late apoptosis rates and (or) necrosis were significantly higher than those in control group (3.03% +/- 0.57%) (P < 0.05), with apoptosis rates and (or) necrosis being (18.31 +/- 0.65%), (45.55% +/- 3.71%), (47.47% +/- 7.01%) in the groups of 50ns, 100ns, 200ns, respectively. A typical DNA ladder pattern of internucleosomal fragmentation was observed in the groups of 50ns and 100ns, but not clear in the 200ns group. RT-PCR results revealed that the mRNA expression of Fas, FasL, caspase8 and Bid were significantly increased in groups of 50ns, 100ns, but significantly decreased in group of 200ns (P < 0.05). Meanwhile, Western blot analysis demonstrated that the Fas, FasL, Caspase-8 and Bid expression were significantly higher in groups of 50ns, 100ns, but significantly lower in group of 200ns (P < 0.05). It indicated that 45kV/cm, 50ns, 100ns nsPEFs could induce apoptosis in ovarian cancer SKOV3 cells and activate Fas-mediated apoptosis pathway.
