ABSTRACT
Objective:To evaluate the relationship between blood transfusion factors (massive transfusion, transfusion of stored red blood cells and anhepatic transfusion) and early postoperative outcomes in the patients undergoing orthotopic liver transplantation.Methods:Patients with end-stage liver disease who underwent orthotopic liver transplantation and intraoperative blood transfusion from January 2021 to March 2022 in our hospital were retrospectively selected, and their clinical data were collected. The patients were divided into massive transfusion group (M group, total red blood cell transfusion ≥10 U) and non-massive transfusion group (NM group) according to the amount of intraoperative blood transfused. The patients were divided into fresh blood group (NS group) and stored blood group (S group, red blood cell storage time > 2 weeks) according to the storage time of red blood cells transfused. The patients were divided into transfusion in anhepatic stage group (group T) and nontransfusion in anhepatic stage group (group NT) according to whether blood was transfused in the anhepatic stage. Multivariate logistic regression, generalized linear model and generalized linear mixed model were used to analyze the relationship between blood transfusion factors and primary outcome measures (postoperative pulmonary complications, circulation overload, acute kidney injury, abdominal infection, thrombosis) and between blood transfusion factors and secondary outcome measures (duration of ICU stay, postoperative hospitalization, postoperative temperature ≥38.5 ℃ at any time point after surgery, postoperative liver and kidney function index, coagulation function index, platelet count and preoperative difference).Results:One hundred and six patients were enrolled in this study. The results of multivariate logistic regression analysis: Massive blood transfusion and infusion of stored blood were risk factors for postoperative pulmonary complications, massive blood transfusion was a risk factor for abdominal infection, Child-Turcotte-Pugh score for liver function and time of anhepatic phase were risk factors for postoperative acute kidney injury, Child-Turcotte-Pugh score was a risk factor for circulatory overload, and age and massive blood transfusion were risk factors for thrombosis ( P<0.05). The results of generalized linear model analysis: Intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged duration of ICU stay, massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase were risk factors for prolonged hospitalization ( P<0.05), and there was no correlation between massive blood transfusion, intraoperative stored blood transfusion and blood transfusion during the anhepatic phase and temperature ≥38.5 ℃ at any time point after surgery ( P>0.05). The results of generalized linear mixed model analysis: There was statistically significant difference in the difference between preoperative and postoperative liver and kidney function indexes, coagulation function indexes and platelet counts in the patients with or without massive transfusion, stored blood transfusion or blood transfusion during the anhepatic phase ( P<0.05). Conclusions:Massive blood transfusion and infusion of stored blood are the main risk factors for early adverse outcomes after orthotopic liver transplantation in the patients.
ABSTRACT
Objective To study the relationship between chemotherapeutic resistance to 5-fluorouracil (5-FU) and Golgi phosphoprotein 3 (GOLPH3) expression in human colon cancer cell line HT29.Methods HT29 cells were divided into four groups:control group,siRNA transfection group,experimental group 1 (30 μmol/L 5-FU),and experimental group 2 (siRNA-GOLPH3 + 30 μmol/L 5-FU).The silencing effect of GOLPH3 gene was detected by RT-PCR and Western blot.The tumor proliferation and formation ability of HT29 cell were measured respectively by MTT and plate colony formation assay.The protein expressions of GOLPH3,P-gp and β-catenin in HT29 cell were detected by Western blot.Results Compared with the control group,the expression level of GOLPH3 mRNA (1.000 ± 0.078 vs.0.147 ± 0.021,t =12.296,P ＜ 0.01) and protein(1.003 ± 0.235 vs.0.077 ± 0.399,t =6.723,P ＜ 0.01),the absorbance(A value) (1.000 ± 0.082 vs.0.769 ± 0.086,t =3.885,P ＜ 0.01) and the tumorigenesis (430 ±36 vs.297 ± 21,t =5.492,P ＜ 0.01) in transfection group significantly reduced.The A value (0.803 ± 0.101 vs.1.050 ± 0.140,t =2.855,P ＜ 0.05;0.242 ± 0.091 vs.1.050 ± 0.140,t =9.664,P ＜ 0.001) and the tumorigenesis (73 ± 8 vs.427 ± 29,t =20.363,P ＜ 0.001;305 ± 22 vs.427 ± 29,t =5.840,P ＜ 0.01) in experimental group 1 and experimental group 2 were significantly lower than that in the control group,while the A value (t =8.264,P ＜ 0.001) and the tumorigenesis (t =17.346,P ＜ 0.001) of experimental group 2 significantly decreased than that experimental group 1.Compared to the control group (0.967 ± 0.094,1.001 ± 0.199,1.000 ± 0.101),the expressions of GOLPH3,P-gp and β-catenin in experimental group 1 (3.634 ± 0.574,2.424 ± 0.261,2.324 ± 0.418) significantly upregulated (t =7.944,P ＜ 0.01;t =7.520,P ＜ 0.01;t =5.330,P ＜ 0.01),while the expressions of these proteins in experimental group 2(0.520 ±0.176,0.466 ±0.159,0.933 ±0.049) were significantly lower than that in experimental group 1 (t =8.983,P ＜ 0.01;t =11.106,P ＜ 0.001;t =5.724,P ＜ 0.01).Conclusion Expression of GOLPH3 is associated with resistance to 5-FU in colon cancer HT29 cell by activating Wnt/β-catenin signal pathway.
ABSTRACT
Objective To observe the expression dynamics of lens-related transcription factors in human embryonic stem cell (hESC) differentiated into lentoid body(LB).Methods A "three-stage" protocol was used for LB directional differentiation from hESC in vitro.The hESC (D0) and three differentiation stages cells were collected to analyze the expression dynamics of lens development-associated transcription factors by high throughput RNA sequencing technology in hESC-induced LB.Western blot and cell immunofluorescence were used to observe the involved genes at protein level.Results During D0-D6,cells became more round and compact.And during D7-D18,cells morphology gradually changed to spindle.At the end of D35,three-dimensional and transparent structurelentoid body (LB) was obtained.RT-PCR results showed that the stem cell related genes reduced and the lens specific genes increased significantly,and the LB was characterized by the expression of crystallins.According to clustering analysis of high throughput sequencing,a distinct difference in transcription factors gene expression was observed between D0 and D32.Meanwhile,the difference between D6 and D18 was minimum.The expressions of preplacodal genes,including DLX3,DLX5,DLX6,HES1,HES4,OTX2 and EYA1 increased remarkably at the first induction stage and then decreased.Lens-specification gene SOX2 declined gradually and then increased.In addition,the expression of PAX6 increased during all three induction stages.Furthermore,lens-differentiation genes including MAB21L1,CMAF,PROXI and PITX3 had no significant change in the early induction stage,but increased significantly at the third induction stage.Conclusions The expression dynamics of lens development-associated transcription factors in the hESC induced LB corresponded to those in vivo,which indicate that this induction system can recapitulate early lens development well and lay the foundation of studying lens embryonic development andtranscription factor associated congenital lens diseases.

ABSTRACT
Objective To evaluate the effect of YunKe on bone metabolism of patients with rheumatoid arthritis (RA). Methods A total of 108 RA patients were divided into YunKe group (n = 72), non-YunKe group (n = 36), and 54 controls. The bone mineral densities (BMDs) of the wrists, hips and lumbar spines were measured by dual-energy X-ray absorptiometry. Moreover , the expression of cross-linked N-telopeptides of type I collagen (NTX) in the serum was detected for statistically analyzing the difference between YunKe group and non-YunKe group. Results In RA group, the BMDs of wrist, hip and lumbar spine declined compared with that of control group (P < 0.001, respectively). In YunKe group, the BMDs of wrist, hip and lumbar spine after 6 months all were improved with statistically significance (P < 0.01, respectively); The differences also were statistically significant when compared with those in non-YunKe group (P < 0.01, respectively). In YunKe group, NTX level in the serum declined after 3 months of the treatment. The difference was statistically significant when compared with that in non-YunKe group (P < 0.001), but the difference disappeared 6 months later. Conclusions The BMD of wrist joints is low and declines in RA patients significantly. The treatment withYunKe improves the BMDs of the wrist , hip and lumbar spine and decreases the serum NTX. This study proposed that YunKe could inhibit the chronic loss of bone mass induced by RA.
ABSTRACT
Objective To establish a close clinical and easy to operate animal artery bypass grafting model by using vascular anastomosis wheel.Methods 15 rabbits that weighted 2.5-3.5 kg were studied.Each animal underwent an end-toend anastomosis of jugular vein and carotid artery by vascular anastomosis wheel.Carotid ultrasound and flow detection were taken immediately and 2 months after surgery respectively,as well as morphology and pathology were recorded to analyze and evaluate the intimal hyperplasia of vein graft and arteriovenous anastomotic site.Results 14 rabbits were successfully established CABG model,however 1 rabbit died of respiratory inhibition caused of excessive anesthesia.Compared with normal carotid artery,the vein bridge showed significantly lower blood flow [(50.81 ± 1.33) ml/min vs.(70.59 ± 0.68) ml/min,P ＜0.01,higher PI(2.15 ±0.07vs.1.22 ±0.04,P ＜0.01)] immediately after surgery.Compared with the vein grafts immediately after surgery,the vein grafts 2 months after surgery showed significantly lower blood flow [(27.46 ± 2.15) ml/min vs.(50.81 ± 1.33) ml/min,P ＜ 0.01].Compared with normal jugular vein,the vein grafts 2 months after surgery showed significantly higher intimal hyperplasia[(160.30 ± 1.78) μm vs.(49.06 ± 2.76) μm,P ＜ 0.01],and higher number of elastic plates(12.36 ± 0.25vs.3.21 ± 0.15,P ＜ 0.01).Conclusion The use of vascular anastomosis wheel to establish an artery bypass graft model can imitate the pathological changes of vein grafts after CABG,which can provide an ideal animal model for various researches on vein grafts.
ABSTRACT
[ ABSTRACT ] AIM: To investigate the effect of advanced oxidation protein product-human serum albumin ( AOPP-HSA) at different concentrations on the permeability of human umbilical vein endothelial cell ( HUVEC) monolayer and the protective effect of NADPH oxidase inhibitor diphenyleneiodonium ( DPI ) against AOPP-HSA exposure. METHODS: Cultured HUVECs were exposed to 200 mg/L HSA (control) or AOPP-HSA (50, 100 and 200 mg/L).The permeability of the endothelial monolayer was assessed by measuring CMFDA-labeled THP-1 cells across the endothelial cells.The cultured HUVECs were treated with HSA (200 mg/L), AOPP-HSA (200 mg/L), or AOPP-HSA (200 mg/L)+DPI (100 μmol/L), and the activation of NADPH oxidase, endothelial monolayer permeability and cytoskeleton rear-rangement were evaluated.RESULTS: AOPP-HSA increased the permeability of the endothelial cell monolayer, and AOPP-HSA at 200 mg/L significantly increased the phosphorylation level of NADPH oxidase in the cells.Treatment with 100 μmol/L DPI obviously attenuated AOPP-HSA-induced NADPH oxidase activation, the increase in the permeability of the cell monolayer and the cytoskeleton rearrangement.CONCLUSION: AOPP-HSA increases the hyperpermeability of HUVEC monolayer via the phosphorylation of NADPH oxidase, and the NADPH oxidase inhibitor DPI reverses such effects.
ABSTRACT
Objective:To explore the productivity of township health services in Guangzhou. Methods:We use a nonparametric Malmquist index approach to analyze total factor productivity change in Guangzhou’s township health service. The panel data was collected between 2009 and 2013. Results: The average growth rate of Guangzhou’s township health service was 18 . 7% from 2009 to 2013 . This growth was mainly due to improved technical progress but not technical efficiency. Pure technical efficiency and scale efficiency have not developed simultaneously. Conclusion:The change in the total factor productivity was positively affected by technical progress, not by strategic management and business decisions inside township health centers.

Objective:To investigate the correlation between the expression of Golgi phosphoprotein 3 (GOLPH3) and the occurrence of apoptosis in colorectal cancer cells (CRC). Methods:Immunohistochemical assays of GOLPH3 and caspase-3 were performed on the paraffin-embedded sections of 62 CRC samples using the standard streptavidin-peroxidase technique. The apoptotic index of the CRCs was examined using the in situ terminal deoxynucleotidyl transferase nick-end labeling technique. The relationship of the GOLPH3 expression, the cell apoptosis, and the clinicopathologic parameters was analyzed. Results:The positive rates of GOLPH3 expression were significantly higher in the CRC tissues (53.2%) than in the normal colorectal mucosa (37.2%;P0.05). The caspase-3 expression and apoptotic index were significantly lower in the GOLPH3-positive CRC tissue than in the GOLPH3-negative tissue (P<0.05). GOLPH3 expression was negatively correlated with the apoptotic index of CRCs based on the Spearman correlation (r=-0.320, P<0.05). Conclusion:GOLPH3 overexpression in CRC tissue is negatively correlated with apoptotic index.
