Sepsis-induced liver injury (SILI) is an important cause of septicemia deaths. BaWeiBaiDuSan (BWBDS) was extracted from a formula of Panax ginseng C. A. Meyer, Lilium brownie F. E. Brown ex Miellez var. viridulum Baker, Polygonatum sibiricum Delar. ex Redoute, Lonicera japonica Thunb., Hippophae rhamnoides Linn., Amygdalus Communis Vas, Platycodon grandiflorus (Jacq.) A. DC., and Cortex Phelloderdri. Herein, we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota. BWBDS protected mice against SILI, which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity. BWBDS selectively promoted the growth of Lactobacillus johnsonii (L. johnsonii) in cecal ligation and puncture treated mice. Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects. Notably, L. johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity, increasing interleukin-10⁺ M2 macrophage production and enhancing intestinal integrity. Furthermore, heat inactivation L. johnsonii (HI-L. johnsonii) treatment promoted macrophage anti-inflammatory activity and alleviated SILI. Our findings revealed BWBDS and gut microbiota L. johnsonii as novel prebiotic and probiotic that may be used to treat SILI. The potential underlying mechanism was at least in part, via L. johnsonii-dependent immune regulation and interleukin-10⁺ M2 macrophage production.

Objective:To discuss the influence of different computed tomography (CT) value assignment methods on dose calculation of intensity modulated radiotherapy (IMRT) plan which designed for nasopharyngeal carcinoma (NPC) and the value assignment methods of IMRT plan for NPC based on magnetic resonance (MR) images.Methods:Simulation CT and MR image of 32 NPC patients in Shandong Cancer Hospital from March 2018 to November 2018 were selected for this study. Populate CT values were obtained by contouring and analyzing the simulation CT of patients′ tissue, including bone, air, brain, eyeball, optic-nerve, lens, parotid, masseter, skin. Pseudo-CT were generated by different CT value assignment methods: CT1: CT value of all tissues was set to 0HU; CT2: CT value of air cavity was set to populate CT value based on CT1; CT3: CT value of Bone was set to populate CT value based on CT2; CT4: CT value of each soft tissue were set to populate CT value based on CT3. The IMRT plan for NPC as Plan0 was designed base on simulation CT. Then Plan0 was transplanted to four pseudo-CT to recalculate the dose and obtain Plan1, Plan2, Plan3 and Plan4, the differences of dosimetric parameters were compared with Plan0. NPC-IMRT plan was designed base on MR images by using the assignment method with CT value of each tissue were set to populate CT value.Results:In the head and neck CT images, the average populate CT values of bone and cavity were 621 HU and -720 HU, respectively. The populate CT values of other soft tissue ranges from -20 HU to 70 HU. The differences of dosimetric indexes of Plan1, Plan2, Plan3, Plan4 decreased sequentially compare to Plan0, the difference of the dosimetry parameters of Plan4 and Plan0 was the smallest. The differences of PTV D 99, PTV D 95, isocenter dose, D mean of all tissues, D max of bilateral eye balls, D max of bilateral lens, D max of bilateral optic nerves, D mean of bilateral parotid, V 20 of bilateral parotid, D 50 of bilateral parotid, D max of spinal cord, D max of brainstem, D 5 of brainstem between Plan4 and Plan0 were all less than 1%. The difference of V 30 in bilateral parotid between Plan4 and Plan0 was less than 1.5%. In the comparison of the pixel dose distribution, the regions of dose distribution difference greater than 1% mainly distributed in the air cavity, bone periphery and the skin. The target area of the IMRT plan for NPC based on MR images met 95% of the prescribed dose, and the dose of each organ at risk was within the dose limit. Conclusions:The assignment method of each tissue and organs set to populate CT value compared with other methods has the least influence on the dose calculation of NPC-IMRT plan, which could meet the clinical requirements. Therefore, it should be the first choice of assignment method when designing NPC-IMRT plan based on MR image.

Objective:To investigate the expression of macrophage migration inhibitory factor (MIF) in bone marrow fluid and peripheral blood of patients with acute myeloid leukemia (AML) and its effect on the expression of interleukin-8 (IL-8) in bone marrow mesenchymal stem cells (BM-MSC).Methods:Fifty bone marrow fluid samples and 50 peripheral blood samples were collected from 50 patients with AML diagnosed in the First People's Hospital of Yunnan Province from October 2017 to January 2019, of which 17 patients were newly diagnosed, 26 patients were complete remission (CR), and 7 patients were partial remission (PR) or non-remission (NR). Fifty plasma samples from 50 healthy subjects and 50 bone marrow fluid samples from 50 patients with iron deficiency anemia were used as the controls. Enzyme-linked immunosorbent assay (ELISA) was used to detect the level of MIF protein in the samples, and the relationship between MIF expression level and clinicopathological characteristics of AML patients was analyzed. BM-MSC was successfully isolated and cultured from 42 bone marrow fluid samples of AML patients, the suitable samples for experiment were chosen and divided into BM-MSC control group (untreated BM-MSC), recombinant human macrophage migration inhibitory factor (rhMIF) group and rhMIF+ISO-1 group. ELISA and real-time fluorescence quantitative polymerase chain reaction were used to detect the expression level of IL-8 protein and mRNA in each BM-MSC group.Results:The expression levels of MIF protein in bone marrow fluid and plasma in AML group were (24.9±7.7) ng/ml and (60.5±12.1) ng/ml, the difference was statistically significant ( P < 0.01), and those in control group were (5.3±2.6) ng/ml and (2.0±1.1) ng/ml, respectively, and there were statistical differences between the two groups (t values were 136.71, 33.97 and 17.58, all P < 0.01). MIF protein expression levels in bone marrow fluid and plasma of AML patients in newly diagnosed group and PR+NR group were higher than those in CR group, and the differences were statistically significant (all P < 0.01). MIF protein expression levels were higher in bone marrow fluid and plasma of patients with ≥60 years of age, peripheral blood white blood cell count ≥30×10 9/L and bone marrow myeloblast ratio > 0.50 (all P < 0.05), but the differences were not statistically significant between patients with different gender (both P > 0.05). The detection results of each BM-MSC group showed that rhMIF promoted the IL-8 expression in BM-MSC at the gene and protein levels, which could be inhibited by the MIF inhibitor ISO-1 (all P < 0.01). Conclusion:The increased expression levels of MIF in bone marrow fluid and plasma of patients with AML are associated with the disease progression, and rhMIF can promote the expression of IL-8 in BM-MSC.

Objective: To investigate the association of fruit and vegetable intake with long-term changes of serum lipid levels in middle-aged Chinese and older Chinese population. Methods: The study analyzed the data collected in the 2004 and 2007-2008 cohorts of China Multicenter Collaborative Study of Cardiovascular Epidemiology. Finally, 4 495 participants from 10 groups in various regions of China, who both were followed up in the two cohorts, were included for data analysis. They were aged 41-66 years in 2004. Fruit and vegetable consumption were collected with a simple food frequency questionnaire. The percent changes (Δ%) of serum TC, TG, HDL-C and LDL-C between the two surveys were calculated. Multivariate linear regression models were used to estimate the association of fruit and vegetable intake in 2004 with percentage changes of serum lipid levels during the two surveys. Results: The proportions of individuals who consumed fruits <250, 250-499 and ≥500 g/week were 24.0%, 21.8% and 54.2%, respectively. The proportions of individuals who consumed vegetables <500 and ≥500 g/day were 76.7% and 23.3%, respectively. Compared with fruit intake <250 g/week, the regression coefficients (95% CI) of ΔTC% in 250-499 and ≥500 g/week group were -1.54 (-2.71, -0.37) and -1.77 (-2.79, -0.76). And the regression coefficients (95% CI) of ΔLDL-C% were -2.43 (-4.39, -0.48) and -2.89 (-4.59, -1.19). Compared with vegetable intake <500 g/d, the regression coefficients (95%CI) of ΔTC% and ΔLDL-C% in vegetable intake ≥500 g/d group were -1.01 (-1.95, -0.06) and -1.83 (-3.41, -0.24). However, fruit and vegetable intake had no relationship with ΔTG% and ΔHDL-C%. Conclusion The consumption of fruit and vegetable was inversely related to long-term changes of TC and LDL-C in middle-aged and older population, but no association was found for changes of TG and HDL-C.

Methods: A cross-sectional study was conducted based on the data cohort of China multicenter collaborative study of cardiovascular epidemiology in 2007-2008. A total of 7227 participants were enrolled including 3304 male and 3923 female at the mean age of (55.6±7.1) years. Tea drinking information was collected by questionnaire; participants were stratified by gender and grouped by regular tea drinking. Relationship between tea drinking and blood lipids, lipoprotein levels were assessed by covariance analysis. Results: There were 3012/7227 (41.7%) participants (male: 58.9% and female: 27.2%) regularly drunk tea. With adjusted age, urban and rural, education level, cigarette smoking, alcohol drinking, body mass index (BMI), daily red meat intake, physical work intensity, exercise intensity, histories of hypertension, diabetes and hypercholesterolemia, in male gender, compared with non-regular tea drinker, regular tea drinker had decreased blood level of low density lipoprotein cholesterol (LDL-C), the difference was -0.12 mmol/L, P=0.0001 and increased triglyceride (TG), the difference was 0.11 mmol/L, P=0.0001; in female gender, regular tea drinker showed increased high density lipoprotein cholesterol (HDL-C), the difference was 0.06 mmol/L, P<0.0001. Conclusion: In our research, regular tea drinking was negatively related to blood LDL-C level and positively related to TG in male gender, while it was positively related to HDL-C in female gender; the above correlations were independent from possible influencing factors. The impact of long term regular tea drinking on blood lipids and lipoprotein levels should be further prospectively investigated in community based middle and aged population.

OBJECTIVETo evaluate the long-term clinical outcomes of fractional flow reserve (FFR)-guided versus intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for intermediate coronary lesions.

METHODSA total of 226 patients with 293 intermediate coronary artery lesions (stenosis of 40%-70%) confirmed by coronary angiography were randomized into 3 groups to undergo PCI for a minimal lumen cross sectional area (MLA)<4 mm(2) (IVUS group, 98 lesions) or for a FFR<0.80 (FFR group, 101 lesions), or to receive standard medical treatment (medication group, 94 lesions). The primary outcome was major adverse cardiac events including death, myocardial infarction, and ischemia-driven target vessel revascularization at 1 year after the index procedure.

RESULTSThe baseline percent diameter stenosis and lesion length were similar between the 3 groups, but more patients in IVUS group than in FFR group received PCI (P<0.001). No significant difference was found in the incidence of major adverse cardiac events between the 3 groups (P=0.182).

CONCLUSIONBoth FFR- and IVUS-guided PCI strategy for intermediate coronary artery disease are associated with favorable outcomes, but IVUS-guided PCI based on the single index of MLA can increase the rate of revascularization therapy.
