ABSTRACT

Objective:Our study was aimed to analyze the therapeutic effect of early sequential enteral nutrition on postoperative rehabilitation in patients with gastric cancer.Methods:Patients with gastric cancer receiving surgery at our hospital from 2016 to 2017 included and the clinical information was prospective collected and analyzed.Patients were randomly divided into two groups using random number table.Patients in group A were sequentially given amino acid type,short peptide type and then whole protein type,while those in group B received whole protein formulation only.The recovery of gastrointestinal function,postoperative systemic inflammatory response,six-minutes walking test,and enteral nutrition-related complications were compared between the two groups.Results:A total of 71 patients were included in this study (Group A 36 cases,Group B 35 cases).There was no significant difference in terms of the restart anal exhaust between the two groups (P > 0.05).Patients in group A had a significantly shorter postoperative hospitalization (t =4.070;P < 0.01) and the earlier restoration of oral intake than that of Group B (t =3.400;P =0.001).One week after surgery,the levels of CRP (t =2.547;P =0.013) and IL-6 (t =3.172;P =0.002) were significant lower in group A when compared with group B.In addition,patients in group A had a significant higher six minutes walk steps than those in Group B [(416.1 + 36.7) m vs (358.9 ± 32.7) m;t =6.927,P < 0.01].However,no significant difference in enteral nutrition-related complications was found between the two groups (P > 0.05).Conclusion:In patients with gastric cancer,early sequential enteral nutrition can effectively accelerate the postoperative rehabilitation.

ABSTRACT

Objective To investigate the degrees of injury severity of sepsis models made by different kinds of Escherichia coli. Methods The 152 mice were randomly divided into control group, DH5α group, 44102 group, and 25922 group, with 38 rats in each group. DH5α group, 44102 group and 25922 group were intraperitoneally injected with 300 μL of Escherichia coli DH5α, 44102 and 25922 at the concentration of 1.0 × 109CFU/kg to prepare sepsis models of different kinds of Escherichia coli. Control group was injected intraperitoneally with the same amount of normal saline. (1) After 8 h, four mice were taken from each group for peripheral blood bacterial culture . (2) After 12 h, ten mice in each group were used for measuring serum levels of TNF-α and IL-6 by enzyme-linked immunosorbent assay (ELISA). (3) Western blot assay was used to determine the serum levels of high-mobility group protein (HMGB1) in four mice of each group. (4) Ten mice in each group were used to measure serum levels of alanine transaminase (ALT), aspartate aminotransferase (AST), creatinine (CR) and blood urea nitrogen (BUN) by automatic biochemical analyzer. (5) After liver, lung and kidney tissues were fixed with formaldehyde, hematoxylin-eosin (HE) staining was performed (n=10 for each group). Results In DH5α group, 44102 group and 25922 group, bacteria, inflammatory cytokines TNF-α, IL-6 and HMGB1 protein, liver and kidney indicators ALT, AST, CR and BUN showed a sequential increasing trend (P<0.01). The severe degrees of alveolar structure damage, hepatic cell infiltration and renal glomerular atrophy were DH5α group, 44102 group and 25922 group in turn. There were no obvious damages of lung, liver or kidney tissues in control group. Conclusion Escherichia coli 25922 induces severe sepsis injury and can be used to study the animal models of the initial inflammatory phase of sepsis. Escherichia coli 44102 induces moderate damage of sepsis and can be used in animal models that do not require definitive sepsis staging experiments. Escherichia coli DH5α induces less damage of sepsis and can be used to explore immunosuppressive therapy of the animal model of sepsis.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the value of miR-29a and miR-10a-5p in predicting 28-day mortality in patients with sepsis-induced acute kidney injury.</p><p><b>METHODS</b>Seventy-four patients with sepsis-induced acute kidney injury (AKI) and 41 patients with sepsis but without AKI (control) were examined for serum levels of miR-29a and miR-10a-5p using RT-PCR. The patients were followed up for 28 days to record their survival. Pearson correlation analysis was used to test the correlations of miR-29a and miR-10a-5p with serum creatinine (Scr), cystatin C (Cys-C), and KIM-1 in patients with AKI. Multivariate logistic regression analysis was used to analyze the correlations of miR-29a, miR-10a-5p, Scr, Cys-C, KIM-1 and other risk factors with the 28-day mortality in patients with sepsis. The predictive value of these indicators for evaluating the prognosis of patients with sepsis was analyzed using ROC curve, and miR-29a combined with miR-10a-5p was assessed for their value in predicting the prognosis of the patients.</p><p><b>RESULT</b>During the follow-up for 28 days, 21 of the 74 (35.53%) AKI patients died. Compared with the survivors, the patients died within 28 days showed significantly increased serum levels of Scr , Cys-C, KIM-1, miR-29a, and miR-10a-5p (P<0.05). Pearson correlation analysis showed that miR-29a and miR-10a-5p were positively correlated with serum Scr, Cys-C, and KIM-1 levels; multivariate regression analysis identified miR-29a and miR-10a-5p as the independent risk factors for mortality in the septic patients. The ROC curve analysis showed that the area under the curve (AUC) of miR-29a and miR-10a-5p was 0.82 (95%CI: 0.71-0.89) and 0.75 (95%CI: 0.64-0.85), and that of Scr, Cys-C and KIM-1 was 0.72 (95%CI: 0.66-0.86) , 0.71 (95% CI: 0.63-0.84) and 0.81 (95% CI: 0.72-0.81), respectively. The AUC of miR-29a combined with miR-10a-5p was significantly greater than that of miR-29a, miR-10a-5p, Scr, Cys-C and KIM-1 alone (P<0.05).</p><p><b>CONCLUSION</b>miR-29a and miR-10a-5p have good predictive value in assessing the 28-day mortality of patients with sepsis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the regular pattern of Cytomegalovirus (CMV)-specific T cells (CTL) immune reconstitution after human leukocyte antigen (HLA) matched sibling donor allogeneic bone marrow(BM) plus peripheral blood hematopoietic stem cell (PBSC) transplantation.</p><p><b>METHODS</b>CTL from seventeen patients after transplantation was detected by flow cytometry, the IFN-γ secretion ability of CTL by enzyme-linked immunospot (ELISPOT) assay, and clonal analysis of TCR Vβ subfamily by gene scan assays. The relationship between CTL reconstitution and CMV infection was studied.</p><p><b>RESULTS</b>Both number and function of recipients CTL reached to normal control level at 30 d post-transplantation. The recipients achieved a high frequency CTL with IFN-γ response and restoration of T-cell receptor β (TCR Vβ) repertoire at one year post-transplantation. CTL with the central memory CD45RO(+)CD62L(+) cell phenotype expanded in PB when CMV was reactivated. The incidence of CMV reactivation was 35.83% (17.91% - 63.10%) after transplantation, and none of them developed CMV disease.</p><p><b>CONCLUSION</b>After HLA matched related donor transplantation using mixed grafts, immune recovery to CMV seems to be early and fast. The incidence of CMV infection and disease are low.</p>

ABSTRACT

The aim of study was to investigate the modulation effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on adhesion molecule expression of memory T lymphocyte in the bone marrow grafts. rhG-CSF was administered in 41 donors by subcutaneous injection for 5 consecutive days. Bone marrow grafts were collected on day 4. The percentages of CD4+ and CD8+, and the expressions of CD49d, CD54, CD62L and CD11a on donor T cells of steady state-bone marrow grafts (SS-BM, n=11) and rhG-CSF primed bone marrow (G-BM, n=30) were analyzed by using multi-color flow cytometry. The results indicated that the percentages of CD4+ and CD8+ T cells were significantly lower in G-BM than those in SS-BM (p<0.05). There were no significant differences in the percentages of memory CD4+ and CD8+ T cells between SS-BM and G-BM (p>0.05). The expressions of CD49d on CD4+ and CD8+T cells were significantly lower in G-BM than that in SS-BM (p<0.05). Compared with SS-BM, the expressions of CD54 on CD4+, memory CD4+ T cells and CD8+ T cells were significantly lower in G-BM (p<0.05). The expressions of CD62L on CD4+ and CD8+ T cells and memory T cells were all significantly lower in G-BM (p values were all less than 0.001). The expressions of CD11a on CD4+, memory CD4+ T cells were significantly lower in G-BM than that in SS-BM (p<0.05). There were no significant differences in the expression of CD11a on CD8+, memory CD8+ T cells between SS-BM and G-BM (p>0.05). It is concluded that the expression of cell adhesion molecules on the CD4+ and CD8+ T cells in G-BM is down-regulated after rhG-CSF treatment of healthy donors.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the optimal time for second allogeneic peripheral blood stem cell grafts (PBSC) harvest from healthy donors after in vivo recombinant human granulocyte colony-stimulating factor application (rhG-CSF).</p><p><b>METHODS</b>Thirty-eight healthy donors of second collection (group A) were treated with subcutaneous rhG-CSF \[5 microgxkg(-1)xd(-1)\] for five consecutive days and followed by leukapheresis on day 5 and 6. The control group (group B) was thirty-eight healthy donors who had received a first PBSC collection previously. Group A was reclassified as group C (< or = 9 months) and group D (> 9 months) according to the 75% quantile of interim time between first and second collection. The quantities of lymphocytes of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD14(+), CD34(+) cells and CD3(+)CD4(-)CD8(-) T cells were determined by multi-color flow cytometry.</p><p><b>RESULTS</b>The median number of CD3(+)CD8(+) (25.51 x 10(8)) and CD34(+) cells (0.51 x 10(8)) in group A were significantly lower than that (31.55 x 10(8) and 0.70 x 10(8) respectively) in group B (P < 0.05), and so did the CD3(+)CD8(+) (23.42 x 10(8)) and CD34(+) cells (0.42 x 10(8)) in group C than that in group B (P < 0.05). There was no statistical difference in median numbers of T cell subsets, monocytes, and CD34(+) cells between group B and group D (P > 0.05). The cell ratios of CD4(+)/CD8(+), CD14(+)/CD3(+) and CD3(+)CD4(-)CD8(-) T/CD3(+) in PBSC in group A, group C, and group D were similar to that in group B (P > 0.05). Sperman analysis showed a positive correlation between the total CD34(+) cells in second collection and the interval time from first to second collection (r = 0.357, P = 0.028).</p><p><b>CONCLUSION</b>Nine months after the first collection maybe an optimal time for the second PBSC collection. For those who undergo second PBSC collection within 9 months, more circulation blood should be extracted to ensure enough immunological and hematopoietic compositions.</p>

ABSTRACT

This study was purposed to investigate the relation of monocyte counts in peripheral blood (PB) at the first collection of allograft to the amount of CD34(+) cells in the mixture of recombinant human granulocyte colony-stimulating factor (rhG-CSF)-primed bone marrow graft (G-BM) and rhG-CSF mobilized peripheral stem cell grafts (G-PB). 70 healthy donors were treated with rhG-CSF [5 microg/(kg.d)] injected subcutaneously for 5 consecutive days. Bone marrow grafts and peripheral blood grafts were harvested on the 4th and 5th days respectively. Blood cell counts at the first collection of allografts were determined by blood analyzer XL2100, the amount of CD34(+) cells in G-BM and G-PB were determined by flow cytometry. The results showed that the monocyte counts in the PB of the 70 healthy donors were (1.15 +/- 0.60) x 10(9)/L. The amount of total CD34(+) cells in the G-BM, G-PB and mixture grafts were (5.85 +/- 2.93) x 10(7), (1.33 +/- 0.77) x 10(8), and (1.92 +/- 0.86) x 10(8) respectively. Pearson and Spearman correlation analysis indicated that the counts of monocyte at the first collection of allografts correlated positively with the amount of total CD34(+) cells in the G-BM (correlation coefficient, r = 0.265, p = 0.027), G-PB (r = 0.340, p = 0.004) and mixture grafts (r = 0.398, p = 0.001). Stepwise Linear Regression Model analysis also showed that the counts of monocytes in the PB correlated positively with the amount of CD34(+) cells in the G-BM, G-PB and mixture grafts (p = 0.027, 0.004 and 0.001 respectively). The sensitivity and specificity of the monocyte counts to predict the amount of CD34(+) cells in the mixture grafts were 71% and 70% respectively (p = 0.007). In conclusion, the monocyte counts in the PB at the first collection of allografts after rhG-CSF treatment of healthy donors may be a simple and practical indicator for harvest of CD34(+) cell amount in the mixture grafts.

ABSTRACT

The study was aimed to analyze the difference of naive and memory CD4(+) and CD8(+) T-cell subsets between steady-state bone marrow (SS-BM) and recombinant human granulocyte colony-stimulating factor (rhG-CSF) mobilized peripheral blood grafts (G-PB). Four CD4(+) and CD8(+) T-cell subsets classified according to the expression of CD45RA and CD62L were determined by three-color flow cytometry. The results showed that the percentage of CD4(+), CD8(+) T-cell subsets and the ratios of CD4/CD8 in G-PB were significantly higher than those in SS-BM (p < 0.05). The percentage of CD4(+) naive T-cells in G-PB was significantly lower than that in SS-BM (p < 0.001). As compared with SS-BM, the percentage of CD4(+) effector memory T-cells was significantly high in G-PB (p < 0.001). There were no significant differences in the percentages of the four CD8(+) T-cell subsets between SS-BM and G-PB (p > 0.05). The percentage of CD4(+)CD62L(+) T-cells in G-PB was significantly lower than that in SS-BM (p = 0.001). The absolute numbers of CD4(+) and CD8(+) T-cell subsets, the eight naive and memory CD4(+) and CD8(+) T-cell subsets were significantly higher in G-PB than those in SS-BM (p < 0.001). It is concluded that the difference of naive and memory CD4(+) and CD8(+) subsets between G-PB and SS-BM may partially explain why the incidence and severity of acute graft-versus-host disease (GVHD) was similar and the incidence of chronic GVHD was different after transplantation with SS-BM or G-PB.

ABSTRACT

The study was purposed to investigate the effect of bone marrow graft collection on the composition of peripheral blood stem cell grafts in healthy donors after recombinant human granulocyte colony-stimulating factor (rhG-CSF) application in vivo. Sixty-two healthy donors were treated with rhG-CSF [5 microg/(kg.d)] injected subcutaneously for five consecutive days. Donors were divided into groups A and B, and 31 donors were there in each group. Bone marrow grafts and peripheral blood stem cell grafts were harvested on the day 4 and 5 respectively in group A. In group B, only peripheral blood grafts were collected on both the day 4 and 5. The quantities of the cell components, CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD14(+), CD34(+) cells and CD3(+)CD4(-)CD8(-) T cells were determined by multi-color flow cytometry. The results showed that median counts of nuclear cells (1.56 x 10(5)), lymphocytes (8.56 x 10(4)), CD3(+) (6.12 x 10(4)), CD3(+)CD4(+) (3.38 x 10(4)), CD3(+)CD8(+) (2.27 x 10(4)), CD14(+) (3.83 x 10(4)), CD34(+) cells (744) and CD3(+)CD4(-)CD8(-) T cells (3588) per microliter of peripheral blood stem cell grafts in group A were similar to counts of nuclear cells (1.40 x 10(4)), lymphocytes (7.34 x 10(4)), CD3(+) (5.32 x 10(4)), CD3(+)CD4(+) (3.06 x 10(+)), CD3(+)CD8(+) (1.83 x 10(4)), CD14(+) (3.21 x 10(4)), CD34(+) cells (554) and CD3(+)CD4(-)CD8(-) T cells (3120) in group B (p > 0.05). There were no difference in the ratios of CD4(+) cells/CD8(+) cells, CD14(+) cells/CD3(+) cells and CD3(+)CD4(-)CD8(-) T cells/CD3(+) cells in peripheral blood stem cell grafts between group A [1.52 (0.54 - 2.87)], [0.57 (0.15 - 1.64)], [0.064 (0.018 - 0.673)] and group B [1.68 (0.31 - 3.35)], [0.59 (0.18 - 1.25)], [0.063 (0.021 - 0.136)] (p > 0.05). It is concluded that no effect of bone marrow graft collection on the composition of peripheral blood stem cell grafts in the same donor is found after rhG-CSF application in vivo, bone marrow grafts and peripheral blood stem cell grafts can be collected respectively or simultaneously.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the cell composition in granulocyte colony-stimulating factor One (rhG-CSF) primed bone marrow grafts (G-BM) from donors with different characteristics.</p><p><b>METHODS</b>hundred and fifty healthy donors were injected subcutaneously rhG-CSF (5 microg x kg(-1) x d(-1)) in five consecutive days. Bone marrow and peripheral blood stem cells were harvested at day 4 and day 5. The number of CD3, CD3+ CD4+, CD3+ CD8+, CD14+ , CD34+ and CD3+ CD4- CD8- cells were determined by multicolor flow cytometry. Cell composition of G-BM from donors with different characteristics, including sex, age, weight, pregnancy were analysed.</p><p><b>RESULTS</b>The absolute number of nuclear cells (NCs), lymphocytes, CD3+, CD3+ CD4+, CD3+ CD8+, CD14+, CD34+ and CD3+ CD4- CD8- cells in G-BM were 31 050 (12 200 -58 100), 2122 (506 - 6618), 1344 (307 - 4791), 692 (145 - 3038), 616 (112 - 2575), 986 (265 -2958), 63 (11 -505) and 83 (9 -390) per microliter, respectively. The number of NCs [33 800 (18 600 - 57 100)], CD34+ cells [76 (22 -505)], and CD3+ CD4+ CD8- regulatory T cells [97 (11 - 380)] harvested from younger donors (aged < or = 38 years) were significantly higher than those from older ones (aged > 38) [28000 (12200-58100), 49 (11-220), and 65 (9 - 389) per microliter (P = 0.027, < 0.001 and = 0.001, respectively)]. Compared with that in donors with peripheral blood monocytes (PBMs) < or = 0.37 x 10(9)/L, higher number of NCs in G-BM [27 150 (13 800 - 58 100) vs 33 550 (12 200 - 57 100), P = 0.005] were collected in donors with PBMs > 0.37 x 10(9)/L. Multivariate analysis showed that donors age (< or = 38 vs > 38 years; P = 0.01) and monocyte number in peripheral blood (< or = 0.37 x 10(9)/L vs > 0.37 x 10(9)/L; P = 0. 003) were factors predicting for NC yields, and donors age ( < or = 38 vs > 38 years; P < 0.001) was factor predicting for yields of CD34+ cells (P < 0.001) and CD3+ CD4- CD8- regulatory T cells (P = 0.001) collection.</p><p><b>CONCLUSION</b>Donor age is a factor for the yields of NCs, CD34+ cells, and CD3+ CD4- CD8- regulatory T cells collection in G-BM, and donor's PBMs more than 0.37 x 10(9)/L, is another factor affecting NCs harvests.</p>
