ABSTRACT

Objective:To investigate the safety and efficacy of FOLFOX (5-fluorouracil + calcium folinate + oxaliplatin) hepatic arterial infusion chemotherapy (FOLFOX-HAIC) combined with immune and targeted therapy as triple combination therapy for patients with single China Liver Cancer Staging (CNLC) Ⅰb hepatocellular carcinoma.Methods:A total of 20 patients with single CNLC Ⅰb hepatocellular carcinoma who received FOLFOX-HAIC combined with immune and targeted therapy as triple combination therapy in the First Affiliated Hospital of Guangxi Medical University from October 2021 to August 2022 were included. The clinical data of all patients was retrospectively analyzed. There were 18 males and 2 females, with the age of (55.1±9.9) years. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Modified Response Evaluation Criteria in Solid Tumors (mRECIST) were used to evaluate the efficacy of FOLFOX-HAIC combined with immune and targeted therapy, and the clinical safety of triple combination therapy was evaluated by common terminology criteria for adverse events 4.0.Results:According to RECIST 1.1, objective response rate of 20 patients was 70.0% (14/20) and disease control rate was 100.0% (20/20) after 2 cycles of treatment (one cycle of FOLFOX-HAIC plus programmed death-1 antibody). According to mRECIST, objective response rate was 90.0% (18/20) and the disease control rate was 100.0% (20/20) after 2 cycles of treatment. Following the treatment, 12 patients (60.0%) received liver tumor resection, and all of them achieved R 0 resection, 2 patients (10.0%) received radiotherapy, 3 patients (15.0%) stopped drug treatment for surgery, 2 patients (10.0%) refused surgery, and 1 patient (5.0%) died of multiple organ failure caused by immune hepatitis. According to pathological results, 3 patients (25.0%, 3/12) achieved pathological complete response, and 4 patients (33.3%, 4/12) achieved major pathological response. In the safety evaluation, the overall incidence of adverse events was 100.0% (20/20). Seven patients (35.0%) had grade 3 adverse events and 1 patient (5.0%) died of multiple organ failure due to immune hepatitis (grade 5). Grade 1-3 adverse events could be relieved after symptomatic treatment. Conclusion:The triple combination therapy of FOLFOX-HAIC combined with immune and targeted therapy is safe and has high objective response rate and disease control rate, which could be a new strategy for the neoadjuvant treatment of hepatocellular carcinoma.

ABSTRACT

Objective:To explore the potential molecular targets and mechanism of Zeqi Decoction in the treatment of lung adenocarcinoma (LUAD) through bioinformatics and cell experiment.Methods:The active components of Zeqi Decoction were collected based on TCMSP database and literature search. Then R software was used to screen differentially expressed genes in LUAD from TCGA and GEO databases. The co-expression module was obtained through weighted gene co-expression network analysis (WGCNA), and the potential targets were obtained after matching and mapping with targets of Zeqi Decoction. Enrichment analysis of GO function and KEGG pathway of targets was conducted. The results were experimentally verified. The lung adenocarcinoma cell lines A549 and H1299 were divided into blank control group and Zeqi Decoction group according to random number table. The inhibition rate of cell proliferation was detected by cell proliferation test (CCK-8); the expression of leukocyte differentiation antigen 36 (CD36) in A549 and H1299 cells was detected by Western blot; the levels of low density lipoprotein receptor (LDLR) and IL-6 were detected by ELISA.Results:Totally 157 anti-lung adenocarcinoma active components and 18 potential targets were obtained, mainly including CD36, IL6, LDLR, etc. The main target of Zeqi Decoction in the treatment of lung adenocarcinoma was lipid metabolism. The results showed that Zeqi Decoction could effectively inhibit the activity of A549 and H1299 cells and the levels of CD36, LDLR and IL-6.Conclusion:Zeqi Decoction can inhibit the inflammatory response by down-regulating the protein expressions of CD36 and LDLR, thereby slowing the proliferation of cells.

ABSTRACT

The study aims to investigate the mechanism of Fengshining fecal microbiota transplants in the intervention of rheumatoid arthritis by ultra-performance liquid chromatography-quadrupole/electrostatic field obitrap high-resolution mass spectrometry (UHPLC-Q-Exactive Orbitrap-MS). All animal welfare and experimental procedures followed the regulations of the Medical Ethics Committee of Shanxi University of Chinese medicine. The rats were randomly divided into normal group, model group, fecal microbiota transplantation group and Tripterygium wilfordii polyglycoside group, and the collagen induced arthritis (CIA) was established. The changes of body weight and metatarpodal lesions of rats were evaluated. The serum of rats in each group was analyzed by liquid chromatography-mass spectrometry and metagenomic technology for differential metabolites and microflora. The protein expression levels of Toll-like receptors (TLR4), myeloid differentiation factor 88 (MyD88) and nuclear factor of kappa B (NF-κB p65) were detected by Western blot. A total of 13 different metabolites, including arachidonic acid, docosahexaenoic acid, 13S-hydroxyoctadecanodienoic acid and L-phenylalanine were screened from serum. Three metabolic pathways, including phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and arachidonic acid metabolism were identified through pathway enrichment. Metagenomic analysis showed that the abundance of g_Bacteroides, g_Prevotella and p_Actinobacteria in CIA group was higher. The abundance of c_Clostridia, g_Akkermansia and s_Akkermansia_muciniphila in fecal microbiota transplantation group is higher. The hierarchical cluster heat map showed that Akkermansia was negatively correlated with L-phenylalanine; while positively correlated with docosahexaenoic acid. Prevotella was positively correlated with L-phenylalanine. Fecal microbiota transplantation group could significantly inhibit the expression of TLR4, MyD88 and p65 proteins in the synovium of rats (P < 0.01). The anti-rheumatoid arthritis effects of fecal microbiota transplantation group is closely related to the intervention of the metabolism of phenylalanine and arachidonic acid, through Akkermansia, Prevotella and other microorganisms, inhibition the TLR4/MyD88/NF-κB pathway.

ABSTRACT

【Objective】 To evaluate the detection and distribution characteristics of anti-P1 in tumor patients, so as to aid in blood screening and transfusion safety. 【Methods】 The clinical data of 112 658 tumor patients who underwent blood preparation and transfusion in our hospital from January 2014 to December 2021 were retrospectively analyzed, and column agglutination technique was used to perform transfusion compatibility test. 【Results】 A total of 1 079 (0.96%, 1 079/112 658) cases were detected with unexpected antibodies, of which 71 (6.58%, 71/1 079) were identified as anti-P1. In anti-P1 cases, 59.15% (42/71) were males; 60.56% had no pregnancy history (P<0.01); 29.58% (21/71), 52.11%(37/71), 12.68%(9/71) and 5.63%(4/71) of anti-P1 patients were with type A, B, O and AB, respectively. 57 cases of anti-P1 patients (80.28%) had difficulty in ABO blood group identification. The incidence of interfering in patients with type B was higher than that of other blood types (P<0.05), as the frequency of w+ in reverse blood typing was higher than other reactive patterns (P<0.05). The incidence of gastric tumor and brain space-occupying lesion in patients with anti-P1 was higher than that in patients with other alloantibodies, while the incidence of gynecological tumors was lower (P<0.05). 【Conclusion】 Anti-P1 affects the ABO blood group identification of tumor patients, and most of them had difficulty in ABO blood group identification. Compared with patients with other alloantibodies, patients with anti-P1 are more likely to be male and suffer from gastric and brain tumors, but less likely from gynecological tumors.

ABSTRACT

【Objective】 To retrospectively analyze the effect of AB platelet secondary compatible transfusion on the efficacy of matched platelet transfusion. 【Methods】 A total of 2 276 cases of platelet transfusion in our hospital were selected from November 2020 to September 2021, including 2 068 ABO matched platelet transfusions and 206 AB platelet secondary compatible transfusions. 117 cases were selected for the first occasion of AB platelet secondary compatible transfusion. The controls were matched transfusion receipts before given AB platelet secondary compatible transfusion, and the experimental group was given matched transfusion after AB platelet secondary compatible transfusion (take the first, second and third transfusion as group 1, 2 and 3, respectively). The platelet count(Plt), platelet elevation (△Plt) and 24 h Plt correction increase index (CCI) of patients before and after platelet transfusion were used as observation indexes to analyze the effect of AB type mis-matched platelet transfusion on the efficacy of matched platelet preventive transfusion by gender, blood type and disease type. 【Results】 Among the 2 276 platelet transfusions, and the △Plt of matched platelet transfusions was significantly higher than that of AB type secondary compatible transfusions, with the mean values at (14±15)×109/L and (11±14)×109/L(P<0.05). The △Plt of female patients was higher than that of male patients (15±16)×109/L vs (13±14)×109/L(P < 0.05). The △Plt values of MDS, NHL and MM were (9±14) ×109/L, (10±12) ×109/L and (8±11) ×109/L, respectively, which were significantly lower than the average value (P < 0.05). For 117 cases of AB platelet secondary compatible transfusion: the Δ Plt was significantly lower than that of the control group and the experimental group, respectively at (9±12) ×109/L, (13±13) ×109/L and (13±12) ×109/L(P<0.05). The effective rate of 24 h CCI was 52.14%, significantly lower than the control group and experimental group (71.59% vs 71.83%), P<0.05; no significant difference was noticed in △ Plt value and 24 h CCI between the experimental group and the control group(P>0.05). The △Plt of the experimental group 3 was significantly lower compared with the experimental group 1, (10±13) ×109/L vs (14±12) ×109/L, P<0.05, and the effective rate decreased from 73.12%(68/93)to 58.70%(27/46), P>0.05. No significant difference in △Plt and the number of effective 24 h CCI cases was found between the experimental group and the control group in terms of gender, blood type and disease type (P>0.05). 【Conclusion】 The △Plt and the effective rate of AB platelet secondary compatible transfusion were lower than those of matched platelet transfusions, and has no significant effect on short term(less than 10 days) matched platelet transfusion.

ABSTRACT

【Objective】 To retrospectively analyze the efficacy of low dose apheresis platelet prophylactic infusion and explore its feasibility. 【Methods】 A total of 392 inpatients with platelet transfusion in our hospital from November 2020 to September 2021 were selected. The conventional dose (1 therapeutic dose) of apheresis platelet transfusion was set as the control group, and the low dose (0.5 therapeutic dose) as the experimental group. Platelet count before and after infusion, platelet elevation value (△PLT) and 24 h platelet count correction increase index (CCI) were observed, and the efficacy of low-dose platelet infusion was analyzed by disease type and gender. 【Results】 The △PLT value and 24h CCI effective infusion rate in control group were higher than those in experimental group: (16±16) ×109 vs (7±10) ×109, 71.94% vs 60.46%, P<0.05. The △PLT value of the control group was about 1.2-3.5 times that of the experimental group, and the effective rate was about 1-1.4 times. In control group, the △PLT (×109) was AML (20±14) >AA (14±14) >ALL (13±12) >NHL (9±8) >MDS (7±6). In the experimental group, the △PLT (×109) was AA (11±18) >AML (8±8) >ALL (5±7) >NHL (5±7) >MDS (6±16). The 24h CCI was AML(163/188, 86.70%)>AA(23/32, 71.88%)>ALL(65/98, 66.33%)>MDS(9/17, 52.94%)>NHL(12/22, 51.55%) in the control group, and AML(133/188, 70.74%)>AA(19/32, 59.38%)>NHL(12/22, 51.55%)>ALL(47/98, 47.96%)>MDS(8/17, 47.06%) in the experimental group. The effective infusion rates of AML and ALL2 in the experimental groups were 70.74% (133/188) and 47.96% (47/98), respectively, significantly lower than 86.7% (163/188) and 66.33% (65/98) in the control group(P<0.05). No significant difference was noticed in the effective infusion rate between the experimental group and the control group for other diseases (P>0.05). 【Conclusion】 Low-dose apheresis platelet prophylactic infusion can alleviate the between supply shortage, with an effective infusion rate of 60.46% (236/392), which has certain clinical application value. Patients with AML, AA or ALL were recommended with low dose platelets, while patients with MDS and NHL were not recommended.

ABSTRACT

Objective:To investigate the clinical, serological and cerebrospinal fluid (CSF) characteristics of patients with Guillain-Barré syndrome (GBS) with positive non-organ-specific autoantibodies.Methods:Eighty-three patients with GBS admitted to the Department of Neurology and Department of Neurocritical Care of the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2020 were retrospectively analyzed, including 33 patients with positive non-organ-specific autoantibodies and 50 patients with negative non-organ-specific autoantibodies. The clinical, serological and cerebrospinal fluid characteristics were compared between the two groups.Results:Thirty-three of 83 (40%) GBS patients were positive for non-organ-specific autoantibodies, and anti-Ro-52 antibody, antinuclear antibody and anti-Sj?gren syndrome A antibody were the most common non-organ-specific autoantibodies. The incidence of autonomic dysfunction (22/33, 67%), respiratory muscle involvement (10/33, 30%), cranial nerve involvement (29/33, 88%), and severe GBS (29/33,88%) was significantly higher in the non-organ-specific autoantibody positive group than in the negative group (10/50, 20%, χ2=18.28, P<0.001;5/50, 10%, χ2=5.54, P=0.019;14/50, 28%, χ2=18.20, P<0.001;28/50, 56%, χ2=9.39, P=0.002). Hyponatremia (9/33, 27% vs 4/50, 8%; χ2=5.59, P=0.018) and liver function impairment (14/33,42% vs 5/50,10%;χ2=11.84, P=0.001) were more likely to occur in the non-organ-specific autoantibody positive group than in the negative group. In addition, the cerebrospinal fluid protein content of the non-organ-specific autoantibody positive group [0.94(0.76) g/L] was significantly higher than that of the negative group [0.59(0.48) g/L, Z=-2.89, P=0.004]. There were no significant differences in gender, age of onset, presence of triggers before onset, time to peak, first symptoms, incidence of sensory disturbances and axonal involvement by electromyography, incidence of hypoproteinemia and hypokalemia, anti-ganglioside antibody positive rate, cerebrospinal fluid pressure, white blood-cell count, and sugar and chloride content between the two groups. Conclusions:GBS patients with positive non-organ-specific autoantibodies may have more extensive autoimmune reactions and more severe nerve damage, and are more likely to have systemic homeostasis disorders. The incidence of autonomic dysfunction, respiratory muscle involvement, cranial nerve involvement and severe GBS is significantly higher, the cerebrospinal fluid protein content is significantly increased, and it is more likely to be complicated with hyponatremia and liver function damage in this group of patients.

ABSTRACT

Based on near infrared spectroscopy and high performance liquid chromatography, this paper established the regression relationship between near infrared spectroscopy and index component content of Huoxiang Zhengqi oral liquid, so as to realize the rapid detection of index component content based on near infrared spectroscopy. Magnolol, honokiol and hesperidin were used as the quality indexes of Huoxiang Zhengqi oral liquid. After using the first derivative and normalization pretreatment method, characteristic variables were screened by CARS, and the correction model was finally established by partial least-squares regression (PLSR) method. The method accuracy was evaluated with the external validation, and the prediction results were tested for significance. The results indicated that when the near infrared spectrum was scanned through the bottle, the model's correlation coefficients of prediction (Rp) were higher than 0.99, the root mean square errors of the prediction models (RMSEP) were all less than 0.008 4, and the relative standard errors of prediction set (RSEP) were all less than 2.83%. There was no significant difference in the predicted results between these two kinds of model. The models established in the non-destructive way have good performance and high prediction accuracy. The rapid and nondestructive way has application value in the quality control of Huoxiang Zhengqi oral liquid.

ABSTRACT

Background Exposure to arsenic can damage trophoblast cells and thus induce abortion, but the mechanism is not known. Objective To investigate the role of miR-145 and PTEN/AKT/mTOR pathway in arsenic-induced abortion and trophoblast cell damage in rats. Methods In the animal experiment, twenty SD pregnant rats were randomly divided into a normal control group (saline gavage) and an arsenic-induced abortion group (10.65 mg·kg−1 sodium arsenite solution was administered by gavage, and the gavage volume was 10 mL·kg−1), with 10 rats in each group. After the miscarriage occurred in the arsenic-induced abortion group (5-6 d after exposure), placental tissues were collected from the two groups. The mRNA expression levels of microRNA-145 (miR-145), phosphatase and tensin homologue (PTEN), kinase B (AKT), mammalian target of rapamycin (mTOR) were detected by real-time quantitative PCR (RT-PCR), and the protein expression levels of PTEN, AKT, mTOR, p-AKT, and p-mTOR were detected by Western blotting. For the in vitro study with immortalized human trophoblast cell line (HTR-8/SVneo cells), a control group, an arsenic exposure group, an miR-145 overexpression group, and an arsenic exposure+miR-145 overexpression group were prepared and cultured for 72 h with 37 °C and 5% CO2, at cell density of 5×105 cells per well, and the arsenic exposure concentration was 20 μmol·L−1. The MTT method was applied to detect cell viability, crystal violet staining to detect the number of monoclonal formation, flow cytometry to detect the level of apoptosis, Image J Angiogenesis Analyzer 1.8.0 plug-in to evaluate total blood vessel length and total blood vessel number; the detection indexes and methods of genes and proteins were the same as "animal experiment". Results (1) In the animal experiment, compared with the normal control group, the expression level of miR-145 mRNA in the placenta tissues of the arsenic-induced abortion group was increased (P<0.05), and the expression levels of PTEN, AKT, mTOR mRNA and proteins, and p-AKT and p-mTOR proteins were decreased (P<0.05). (2) For the in vitro study, compared with the control group, the cell viability rate, number of monoclonal formation, total vessel length, and total vessel number were decreased, and the apoptosis rate was increased in the arsenic exposure group, the miR-145 overexpression group, and the arsenic exposure+miR-145 overexpression group (P<0.05). Compared with the arsenic exposure group and the miR-145 overexpression group, the cell viability rate, number of monoclonal formation, total vessel length, and vessel number were decreased, and the apoptosis rate was increased in the arsenic exposure+miR-145 overexpression group (P<0.05). Compared with the control group, the levels of miR-145 mRNA in the arsenic exposure group, the miR-145 overexpression group, and the arsenic exposure+miR-145 overexpression group increased (P<0.05), the expression levels of PTEN, AKT, mTOR mRNA and protein and the expression levels of p-AKT and p-mTOR protein were decreased (P<0.05); compared with the arsenic exposure group and the miR-145 overexpression group, the level of miR-145 mRNA in the arsenic exposure+miR-145 overexpression group was increased (P<0.05), and the levels of PTEN, AKT, mTOR mRNA and protein as well as p-AKT and p-mTOR protein were decreased (P<0.05). Conclusion miR-145 might be related to abortion due to arsenic exposure. miR-145 could inhibit the proliferation and angiogenesis of trophoblast HTR-8/SVNEO cells, and promotes their apoptosis; the mechanism may be related to the inhibition of PTEN/AKT/mTOR pathway.

ABSTRACT

Objective To explore the expression and significance of serum DKK1 in patients with gastric cancer. Methods We selected 170 gastric cancer patients (gastric cancer group) and 170 subjects with non-gastric cancer during the same period (control group). ELISA was used to detect the DKK1 level. The ROC curve was used to evaluate the diagnostic performance, and we analyzed the relation between DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, TNM stage, infiltration depth, lymph node metastasis, liver metastasis, vascular invasion, perineural invasion. Results The serum DDK1 level in GC patients was higher than that in control group (P < 0.0001). ROC curve showed that the possible optimal cut-off value of DKK1 for gastric cancer patients was 167.8 pg/ml, AUC was 0.908, sensitivity was 80.59%, and specificity was 84.71%. There was no significant relation between the serum DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, liver metastasis, vascular invasion or distant metastasis (all P > 0.05). However, DKK1 level was significantly related with TNM stage, infiltration depth, lymph node metastasis and perineural invasion (all P < 0.05). Conclusion Serum DKK1 level is higher in gastric cancer patients than that of control group and related with the severity of lesions, which indicates that serum DKK1 may be a potential biomarker for gastric cancer screening.

ABSTRACT

Objective:To investigate the application value of endoscopic ultrasound (EUS) in tumor staging of adenocarcinoma of the esophagogastric junction (AEG) after neoadjuvant concurrent chemoradiotherapy.Methods:The clinical data of 40 patients diagnosed with stage Ⅲ AEG and treated with neoadjuvant concurrent chemoradiotherapy from January 2016 to December 2021 in the First Affiliated Hospital of Hebei North University were retrospectively analyzed. EUS was used to perform preoperative tumor staging after neoadjuvant concurrent chemoradiotherapy to evaluate the therapeutic effect, and the consistency between EUS and postoperative pathological staging was analyzed.Results:In 40 AEG patients after neoadjuvant chemoradiotherapy, the EUS staging was stage yp-uT 2 in 12 cases, stage yp-uT 3 in 18 cases, and stage yp-uT 4 in 10 cases. The postoperative pathological staging was stage pT 1 in 2 cases, stage pT 2 in 14 cases, stage pT 3 in 12 cases, and stage pT 4 in 12 cases. Taking postoperative pathological results as the gold standard, the accuracy of EUS for T staging after neoadjuvant chemoradiotherapy was 62.5%, and the accuracy, sensitivity and specificity for stage T 2 were 58.3%, 50.0% and 80.8%, respectively. The accuracy, sensitivity and specificity for stage T 3 were 61.1%, 91.7% and 75.0%, respectively. The accuracy, sensitivity and specificity for stage T 4 were 70.0%, 58.3% and 89.3%, respectively. The Kappa value of the consistency test between yp-uT staging and pT staging was 0.453. The EUS staging of lymph nodes was stage yp-uN 0 in 15 cases, stage yp-uN 1 in 10 cases, stage yp-uN 2 in 10 cases, and stage yp-uN 3 in 5 cases. The postoperative pathological staging was stage pN 0 in 18 cases, stage pN 1 in 7 cases, stage pN 2 in 7 cases, and stage pN 3 in 8 cases. Taking postoperative pathological results as the gold standard, the accuracy rate of EUS for N staging after neoadjuvant chemoradiotherapy was 57.5%, and the accuracy, sensitivity and specificity of EUS for stage N 0 were 73.3%, 61.1% and 81.8%, respectively. The accuracy, sensitivity and specificity for stage N 1 were 50.0%, 71.4% and 84.8%, respectively. The accuracy, sensitivity and specificity for stage N 2 were 40.0%, 57.1% and 81.8%, respectively. The accuracy, sensitivity and specificity for stage N 3 were 60.0%, 37.5% and 93.8%, respectively. The Kappa value of the consistency test between yp-uN staging and pN staging was 0.409. Conclusions:EUS is not accurate for T staging in patients with stage Ⅲ AEG after neoadjuvant therapy, but has high sensitivity for stage T 3 and high specificity for stage T 4. EUS has low sensitivity for N staging in patients with stage Ⅲ AEG after neoadjuvant therapy, but has high specificity for stage N 3.

ABSTRACT

Objective:To investigate the effect of different primary sites of colorectal cancer on early recurrence after radical resection of metastatic tumor clinical risk score (CRS).Methods:The data of colorectal cancer liver metastasis (CRLM )surgically resected between Jan 2015 and Feb 2020 were retrospectively analyzed at Li Huili Hospital and Ningbo University People's Hospital. Risk factors leading to early recurrence after CRLM resection were analyzed by univariate analysis, and the significant results were then subjected to multifactorial analysis by COX regression model. Kaplan-Meire method was used to analyze the effect of primary site on disease-free survival at 1 year after CRLM resection in different CRS subgroups.Results:A total of 209 patients were included in the study, including 143 patients with primary tumors in the left colon and 66 in the right colon. One hundred and three (49.3%) patients with recurrence within 1 year.Univariate analysis showed that primary tumor site, neoadjuvant chemotherapy, and CRS were correlated with recurrence. Multivariate analysis showed that right colon cancer, poor efficacy of neoadjuvant therapy, and high risk of CRS were independent risk factors (all P<0.05). Patients with an overall low CRS risk group and low CRS after treatment, had a higher recurrence rate (all P<0.05) within 1 year when primary tumor located right colon. Conclusion:The location of the primary tumor in the right colon is an independent risk factor for recurrence within 1 year after radical surgery in patients with CRLM.

ABSTRACT

【Objective】 To explore the corresponding strategies of blood preparation for placenta previa operation in our hospital according to the situation of blood transfusion during and after operation. 【Methods】 Ninety pregnant women with placenta previa (complete, partial or marginal) undergoing the caesarean operation and blood transfusion in our hospital from January 2011 to September 2020 were selected as the research objects. The corresponding data about intraoperative/postoperative blood loss, blood transfusion and blood preparation were collected, analyzed and compared. 【Results】 There was no significant differences in age between complete and marginal placenta previa(P>0.05), but significant differences in intraoperative/postoperative blood loss and the units of blood transfusion (P1 000 mL). The difference between ordering and transfusion units of complete and marginal placenta previa were 0.4 and 0, respectively. When the complete placenta previa was accompanied by placenta increta or placenta percreta, the blood loss was larger (>1 000 mL) and the units of blood transfusion ranged from 4.5 U to 6 U, while the blood loss was generally low (≤1 000 mL) and the units of blood transfusion was concentrated at 3 (2, 4) U without placenta accreta nor implantation.The difference between ordering and transfusion units of complete placenta previa with non-implantation, placenta accreta, placenta increta and placenta percreta were 0.165, 0.33, 0.5 and 1, respectively. 【Conclusion】 For marginal placenta previa, 3U blood is recommended for routine preparation, 3U blood for complete placenta previa with non-implantation or placenta accrete, and 4.5-6U for complete placenta previa with placenta increta or placenta percreta.

ABSTRACT

【Objective】 To analyze the characteristics and influencing factors of blood transfusion in patients undergoing hepatectomy with hydatid hepatica, so as to provide perioperative blood security of these patients. 【Methods】 A retrospective analysis was performed on 40 hydatid hepatica patients who underwent hepatectomy from June 2011 to June 2021, and they were divided into the transfusion group (n=15) and the non-transfusion group (n=25). The difference in basic information, operative information, blood routine, coagulation function, biochemical parameters and thromboelastogram between the two groups were compared, and the characteristics of perioperative blood transfusion were analyzed. 【Results】 Fifteen(37.5%, 15/40) patients undergoing hepatectomy received blood transfusion, among which 2(5%, 5/40), 10(25%, 10/40) and 11(27.5%, 11/40) received preoperative, intraoperative and postoperative transfusion, respectively. The average transfusion of suspended red blood cells, plasma and cryoprecipitate were 4.77 U, 1 355 mL and 11.9 U respectively, without any adverse reactions of blood transfusion occurred. The operative time, intraoperative blood loss, the number of patients with tumor diameter ≥10 cm/ diameter <10 cm, the number of patients with cholecystectomy, postoperative PT, postoperative APTT and average hospital stay in the transfusion group were higher than those in the non-transfusion group(P<0.05), and the postoperative FIB was lower than those in the non-transfusion group(P<0.05). The blood test results showed that the WBC, AST, ALT and INR 24h after operation were significantly higher than those before operation (P<0.05), while RBC, Hb, ALP, FIB and Angle were significantly lower than those before operation(P<0.05). There were statistically significant differences in WBC, RBC, Hb, ALT, ALP and INR between preoperative and postoperative 3~5 days(P<0.05). The differences of WBC, AST, ALT and FIB 3~5 days after surgery were statistically significant compared with 24 hours after surgery(P<0.05). 【Conclusion】 The size of hepatic hydatid mass, cholecystectomy, intraoperative blood loss, operative time, postoperative PT, postoperative APTT and postoperative FIB were important factors affecting perioperative blood transfusion after hepatectomy, and the main transfusion components were plasma and cryoprecipitate.

ABSTRACT

【Objective】 To analyze the safety of apheresis granulocyte(AG) collection from blood donors mobilized by G-CSF and apheresis granulocyte transfusion efficacy in patients. 【Methods】 The blood routine results, collection process and follow-up of blood donors mobilized by G-CSF before and after AG collection were collected to analyze the safety of AG collection, and the blood routine results, clinical symptom improvement and treatment outcome of patients before and after AG transfusion were collected to analyze the transfusion efficacy. 【Results】 A total of 27 blood donors donated 29 U AG, with collection time at (229±20)min, circulating blood volume at (9 890±1 107)mL, and the dosage of anticoagulant at (1 002±97)mL.Two blood donors had adverse reactions to blood donation, and the AG collection was carried out after treatment.After G-CSF mobilization, WBC increased significantly from (5.61±1.06) ×109/L to (22.85±5.23) ×109/L, while RBC, Hb, Hct and Plt showed no significant change.The blood routine returned to the level before G-CSF mobilization 1-2 days after blood donation.No physical discomfort occurred during the one week after blood donation.Four patients with granulocyte deficiency complicated with multidrug-resistant bacterial infection, who failed to respond to antibiotic treatment, were transfused with 29 U AG, with no adverse reactions and no obvious change in blood routine, but the infection symptoms were improved significantly judged from clinical manifestation, bacterial culture results, temperature monitoring and CT examination, suggesting that the AG infusion was effective.Among the 4 patients, 1 was cured and discharged, 1 gave up treatment, 1 died of sepsis, and 1 died of multiple organ failure. 【Conclusion】 It is safe to collect AG from blood donors mobilized by G-CSF through blood cell separator, and the AG products basically meet the national quality requirements and the treatment needs.Sustained high-dose AG transfusion has a significant effect on infection control in patients with agranulocytosis combined with refractory multidrug-resistant bacterial or fungal infection.

ABSTRACT

【Objective】 To explore the clinical application of a universal platelet product for emergency, which was prepared by suspending O-type apheresis platelet concentrate in AB-type fresh frozen plasma, so as to improve the platelet support ability in emergency and special treatment. 【Methods】 A retrospective analysis of 21 hematological patients, which was divided into 3 groups of platelet transfusion schemes: universal type, AB type and the same type, was performed to analyze the differences in PLT, dose, 24 h PPR, 24 h CCI, follow-up platelet transfusion units and interval, and adverse reactions to transfusion. 【Results】 1)There was no significant difference in PLT, MPV, PDW, K, MA and pH between the initial O-type apheresis platelets and the finished universal platelets (P>0.05). The titers of both anti-A and anti-B in the universal platelets were less than 2. 2) Twenty-one patients were transfused with universal platelet for 27 occasions[1~5 occasions per person; 1 (0.4, 1.0) dose per time]. No adverse reactions to transfusion occurred. 3)There was no significant difference in the effective rate of 24 h CCI and 24 h PPR between the three groups after transfusion(P>0.05). The time interval of the first subsequent platelet transfusion between the compatible group and the universal group was longer than that in the AB-type transfusion group, with significant difference(P0.05) among three groups. 【Conclusion】 In emergency, the application of this universal platelet product can make hematological patients get timely and effective treatment. Its accessibility and effectiveness can be elevated and the infusion interval can be prolonged by improving the preparation method and storage conditions. This product is not only expected to improve the platelet support capacity for patients with emergency and also those undergoing hematopoietic stem cell transplantation during the blood type conversion period, but also may be a practical method to alleviate the contradiction between platelet supply and demand.

ABSTRACT

Objective:To explore the effects of bilateral arm transcutaneous electrical acupoint stimulation (TEAS) based on mirror therapy (MT) on upper limb function of subacute stroke hemiplegic patients. Methods:From September, 2017 to October, 2019, 48 subacute stroke hemiplegic patients were randomly divided into control group (n = 24) and experimental group (n = 24). All the patients accepted routine rehabilitation and MT, while the experimental group received bilateral arm TEAS and the control group received sham TEAS, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT) and modified Barthel Index (MBI) before and after treatment. Results:All the scores of FMA-UE, ARAT, WMFT and MBI improved in both groups after treatment (|t| > 11.870, P < 0.001), and improved more in the experimental group than in the control group (|t| > 2.678, P < 0.05). Conclusion:Bilateral arm TEAS based on MT can promote the upper limb function of subacute stroke hemiplegic patients.

ABSTRACT

【Objective】 To analyze ABO subtype samples from tumor patients using both blood group serology and molecular biology technology. 【Methods】 32 samples of ABO subtype, identified by routine blood group serology in the Department of Transfusion, of solid tumor patients treated in Cancer Hospital of Chinese Academy of Medical Sciences from July 2014 to December 2019 were analyzed by sequence specific primer polymerase chain reaction (PCR-SSP) and gene sequencing (PCR-SBT). 5 samples were detected by PCR-SSP, 28 PCR-SBT, 1 both PCR-SSP and PCR-SBT. The serological and genotyping results were comparatively analyzed. 【Results】 66% (21/32) of the samples in this study were confirmed as ABO subtypes or harbored mutations by genotyping assays, including 7 cases of B(A).04, 2 of B(A).02, 1 of cis AB.01, 3 of BW.12, 4 of BEL.03, 1 of AEL.02, 1 of B 974G>C, 1 of A 797insT, and 1 of A 617C>G. Among the 21 subtype samples or harbored mutations, 15 had the same blood group serology and genotyping results, and 6 had no A or B antigen detected in the serological adsorption-elution test. An additional 34% (11/32) of the samples had no variants in the gene responsible for ABO subtype detected by molecular analysis. 【Conclusion】 Molecular biology techniques can assist in the identification of difficult ABO blood types caused by weakened antigens or antibodies, and subtypes in solid tumor patients, which is an important auxiliary method for accurate identification of difficult ABO blood group.
