Objective To guide fluid management for sever heart failure patients by using PICCO indicators, in order to direct clinical fluid management and nursing care. Methods Sixty-four heart failure patients with level IV cardiac function were randomly divided into the control group and the experimental group according to random number table, and each one had 32 patients. Fluid management for patients in the control group was implemented with CVP monitoring technology, while the patients in the experimental group accepted PICCO monitoring technology as fluid management. Then compare these indicators between the two groups--length of stay in ICU, mortality rate of 28 days, daily fluid intake, output and time of achieving negative fluid balance, and observe the change of cardiac function index (CFI) and capacity indicators (ITBVI, GEDVI, EVLWI) in the experiment group before and after treatment. Results Indicators of ITBVI、GEDVI、EVLWI in the experiment group recovered to normal state and CFI improved. The indicators which had mentioned above was (1 203.41±111.08) ml/m2, (1 087.78±66.91) ml/m2, (12.91±3.54) ml/kg, (2.91±0.29) L·min-1·m-2 respectively when before the treatment, while the values after the treatment was (895.50 ± 50.27) ml/m2, (728.19 ± 73.33) ml/m2, (6.51 ± 0.75) ml/kg, (4.61 ± 0.69) L · min-1 · m-2, the difference was significant (t=-18.52-54.42, P<0.05). The length of stay in ICU, mortality rate of 28 days, daily fluid intake, output and time of achieving negative fluid balance of the experimental group were significantly lower than those in the control group(t=-17.19,-76.80,-12.38, χ2=3.26, P<0.05). Conclusions PICCO monitoring indicators are better than CVP method in the aspect of fluid management for patients with sever heart failure, which can increase the rescue success rate, promote the treatment effect, improve prognosis, and promote the rehabilitation of patients.

OBJECTIVETo investigate the quality of life of cleft lip and/or palate children's parents and discuss the factors to provide the oretical basis for improving the quality of life of these parents and promoting the healthy growth of children with cleft lip and/or palate.

METHODSA total of 115 parents whose children had cleft lip and/or palate surgery treatment were selected as the experiment group, and another 198 parents (with healthy children having a similar age with those in the experiment group) as the control group. The experiment group was divided into three subgroups according to different types of cleft lip and/or palate: cleft Lip (CL), cleft palate (CP), cleft lip and palate (CLP). The experiment group and the control group were both divided into four subgroups according to age: 0-1, 1-3, 3-6 years old, and more than 6 years old. The experiment group and the control group were both divided into three subgroups according to education: junior middle school and the following, high school and technical secondary school, junior college degree or above. The GQOLI-74 scale was selected to assess the experiment group and the control group. SPSS 16.0 software was used to analyze data.

RESULTS1) The experiment group had no significant difference with the control group in terms of the overall score and the scores of various children ages. 2) The scores of every item had no significant difference in CL, CP, CLP subgroup (P > 0.05). 3) The quality of life scores and scores of psychological function dimension and social function dimension of parents with 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P<0.05). The scores of social function dimension of parents with 0-1, 1-3, 3-6 years old patients were obviously lower than those of parents with more than 6 years old patients (P < 0.05). The other items had no significant difference. 4) The scores of material life dimension and social function dimension of parents with junior college degree or above were higher than those of parents with junior middle school degree and the following (P < 0.05). The scores of social function dimension of parents with high school and technical secondary school degree were higher than those of parents with junior middle school degree and the following (P < 0.05).

CONCLUSIONNo difference was observed in the quality of life between cleft lip and/or palate children's parents and normal group. The parents with the low age children with cleft lip and/or palate and low-levels of education need more help and support to improve quality of life.

Objective: To investigate the cognition of medical staffs in grass-roots hospitals to clinical pharmacy practice and clini-cal pharmacists to provide some references for the further development of clinical pharmacy service. Methods: Totally 625 clinicians and nurses from 4 grass-roots hospitals were surveyed using a questionnaires, and the results were statistically analyzed. Results: The clinicians and nurses had an approval attitude towards clinical pharmacy practice and clinical pharmacists with small difference (overall average score was 3. 73±0. 86 and 3. 70±0. 90, respectively). They showed the highest cognition to clinical pharmacy practice, and the lowest cognition to the development, theory and regulation of clinical pharmacy and clinical pharmacists. Conclusion: It is necessary for grass-roots hospitals to carry out some comprehensive measures to improve clinical pharmacists' professional quality and general ca-pacity, promote the consummation of rules and regulations, and enhance cognition of medical staffs to clinical pharmacy practice and clinical pharmacists so as to promote the development of clinical pharmacy practice, which is helpful in training better clinical pharma-cists.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Objective To investigate the quantity and function of CD8+T cells in peripheral blood of pa-tients with repeated implantation failure(RIF).Methods Thirty-seven patients with RIF and 19 healthy controls were enrolled in this study.The peripheral blood and endometrium were collected during the mid-luteal phase.The percentage of peripheral CD8+T subsets and the levels of perforin and granzyme B of peripheral CD8+T cells were determined by flow cytometry assay.The percentage of endometrial CD8+T cells was detected by IHC,the produc-tion of perforin and granzyme B of endometrial CD8+T cells was detected by IF. Results Compared with the con-trol group,the percentage of peripheral CD8+T cells in patients with RIF was not significantly changed(37.22% vs. 37.15%,P>0.05).However,the porportion of endometrial CD8+T cells in the RIF group was higher than that in the control group(1.99% vs.3.77%,P<0.001).The levels of perforin and granzyme B in peripheral blood and en-dometrial CD8+T cells in patients with RIF were similar with those in the control group.Conclusions Compared to the control group,the percentage of endometrial CD8+T was markedly upregulated in patients with RIF.However, the production of perforin and granzyme B were similar between the control group and the RIF group.

Objective: To investigate the effects of oxidized low-density lipoprotein/β2 glycoproteinⅠ/β2 glycoproteinⅠantibody (oxLDL/β2GPⅠ/β2GPⅠ-Ab) complex on the phenotypic transformation and lipid transpoters on the surface of rat thoracic aorta smooth muscle cell line (A7r5), and their correlation with toll-like receptor 4 (TLR4) signaling pathway. Methods: A7r5 cells were stimulated by oxLDL, oxLDL/β2GPⅠ complex, oxLDL/β2GPⅠ-Ab complex, β2GPⅠ/β2GPⅠ-Ab complex and oxLDL/β2GPⅠ/β2GPⅠ-Ab complex respectively, and then total RNA and protein were collected. The expressions of α-smooth muscle actin (α-SMA), macrophage surface marker CD68, galectin-3 (LGALS3), scavenger receptor class B member 3 (CD36) and ATP-binding cassette transporter A1/G1 (ABCA1/ABCG1) were detected by real-time quantitative PCR (RT-qPCR), western blot and immunofluorescence (IF) respectively. The roles of TLR4 and its downstream signaling molecules in the phenotypic transformation and expression changes of lipid transporters of A7r5 cells induced by oxLDL/β2GPⅠ/β2GPⅠ-Ab complex were investigated by the pretreatment of TLR4 blocker TAK-242 (5 μmol/L) or c-Jun N-terminal kinases 1/2 (JNK 1/2) blocker SP600125 (90 nmol/L). Results: The oxLDL/β2GPⅠ/β2GPⅠ-Ab complex significantly increased the levels of CD68 and LGALS3, and decreased the level of α-SMA, while TAK-242 could reverse this phenomenon. The oxLDL/β2GPⅠ/β2GPⅠ-Ab complex could promote the expression of CD36 and inhibit the expression of ABCA1/ABCG1, while TAK-242 and SP600125 could reverse this process. Conclusion The oxLDL/β2GPⅠ/β2GPⅠ-Ab complex promotes the phenotypic transformation of A7r5 cells to macrophage-like cells, regulates the expression of lipid transport-related molecules and enhances the ability of lipids transport into cells. TLR4 and JNK1/2 are closely related to this process.

Objective: To investigate the effects of β2 glycoprotein Ⅰ/anti-β2 glycoprotein Ⅰ complex (β2/aβ2) on oxidized low density lipoprotein (oxLDL)-mediated lipid accumulation and focal adhesion kinase (FAK) activation in THP-1 macrophage, as well as the role of Toll-like receptor 4 (TLR4) during the process. Methods: THP-1 cells were differentiated into THP-1 macrophage by PMA (100 ng/mL). THP-1 macrophages were treated with RPMI 1640 medium, oxLDL, oxLDL+β2/aβ2 or oxLDL+lipopolysaccharide (LPS). The mRNA expressions of lipid transportation molecules, ACAT1, ABCA1 and ABCG1 were detected by RT-qPCR. Intracellular total cholesterol (TC) and free cholesterol (FC) in THP-1 macrophages were evaluated by Trinder assay, then the content and proportion of intracellular cholesteryl ester (CE) were calculated. The expression and phosphorylation of FAK were detected by immune fluorescence, RT-qPCR and western blot. To evaluate the role of TLR4, THP-1 macrophages were pre-treated with or without TLR4 inhibitor TAK-242 (1 μg/mL). Results: β2/aβ2 treatment significantly inhibited oxLDL-mediated lipid accumulation and FAK expression and phosphorylation in THP-1 macrophages, which could be reversed by TLR4 blockage. Conclusion β2/aβ2 inhibits the oxLDL-mediated lipid accumulation and FAK activation of THP-1 macrophage, which is related to the function of TLR4.

In clinical practice, red blood cell infusion needs to be based on the patient′s hemoglobin level. However, different guidelines recommend different thresholds for red blood cell infusion and the timing of blood transfusion initiation is still controversial due to the presence of these different thresholds. Meanwhile, the use of allogeneic blood products carries a certain risk of transfusion-related infections or organ damage. Therefore, initiating red blood cell infusion requires more evidence. This review discusses some new methods, namely central venous oxygen saturation, arterial venous oxygen difference, near-infrared spectroscopy, and perioperative transfusion trigger score. It aims to help evaluate blood transfusion trigger and provide reference for doctors when making transfusion decisions.
