ABSTRACT
Objective:To explore the efficacy and safety of low-dose rabbit anti-human thymocyte globulin (rATG) for induction therapy of kidney transplantation (KT) in children.Methods:From October 2018 to May 2021, clinical data were reviewed retrospectively for 77 pediatric KT recipients on a low-dose rATG induction protocol.Recipient/graft survival rate, renal function recovery, acute rejection (AR) and adverse reactions were observed at 1 year post-operation.The postoperative changes of renal function were examined by Friedman’s test; According to the preoperative baseline data, Pearson’s Chi-square or Fisher's exact test was utilized for examining the influencing factors of postoperative AR.Results:A total of 16(20.78%) recipients had AR within the first 6 months post-operation.The incidence of delayed graft function (DGF) was 14.29%(11/77); The incidence of severe infection post-transplantation 18.18%(14/77), the infection rate of BK virus 25.97%(20/77) and the incidence of neutropenia 32.47%(25/77).The recipient/graft survival rate at 1 year post-operation was 97.40%(75/77) and 94.81%(73/77) respectively.Chi-square test indicated that the incidence of postoperative infection in children with body weight ≤30 kg and height ≤138 cm was 28.95%(11/38) and 27.50%(11/40) respectively, Both were higher than 7.69%(3/39) and 8.11%(3/37) of children with body weight >30 kg and height>138 cm.The difference between groups was statistically significant ( P=0.016 and 0.028). Conclusions:Low-dose rATG is generally excellent in preventing AR in pediatric KT recipients.And the risk of related AR may be lower.The infection rate of recipients with decent preoperative development is low.
ABSTRACT
Objective:To investigate the effect of chemotherapy combined with sorafenib on the prognosis of FLT3 internal tandem duplication (FLT3-ITD)-positive acute myeloid leukemia and to find a more effective treatment.Methods:The clinical data of 60 patients who were newly diagnosed with acute myeloid leukemia and who received treatment in The Second Affiliated Hospital of Qiqihar Medical University from January 2015 to January 2017 were retrospectively analyzed. The patients were divided into three groups according to whether they were positive for FLT3-ITD and the treatment method they used. The observation group (FLT3-ITD-positive, n = 19) were treated with sorafenib based on routine chemotherapy. The control group 1 (FLT3-ITD-positive, n = 21) was treated only with routine chemotherapy. The control group 2 (FLT3-ITD-negative, n = 20) was treated only with routine chemotherapy. After the first and fourth courses of treatment, clinical efficacy was compared among the three groups. Results:After the first course of treatment, the complete remission rate in control group 2 was 50.0% (10/20), which was significantly higher than 15.8% (3/19) in the observation group and 4.8% (1/21) in the control group 1 ( H = 13.39, P < 0.05). After the fourth course of treatment, the complete remission rate in the observation group, control group 2, and control group 1 was 63.2% (12/19), 60.0% (12/20), and 4.8% (1/21), respectively, and the differences were statistically significant ( H = 19.21, P < 0.05). Four-year follow-up results showed that the median survival time in the observation group, control group 1, and control group 2 was 36.63, 24.15, and 45.00 months respectively. The event-free survival in the observation group, control group 1, and control group 2 was 18.00, 9.82, and 24.90 months, respectively. The median survival time and the event-free survival in the control group 2 were significantly longer than those in the observation group and control group 1 ( χ2 = 19.93, 23.04, both P < 0.001). Conclusion:Chemotherapy combined with sorafenib for treating newly-diagnosed FLT3-ITD-positive acute myeloid leukemia can provide comprehensive benefits and have advantages for survival over chemotherapy without sorafenib and chemotherapy alone.

ABSTRACT
Objective:To explore the clinical efficacy of vascular interventional therapy in children with transplantation renal artery stenosis(TRAS).Methods:From January 2013 to September 2021, retrospective analysis was performed for clinical data of 238 TRAS children.Peak systolic velocity(PSV)of transplant renal artery, interlobular artery PSV, transplant renal artery PSV/ interlobular artery PSV(post PSV ratio)and serum creatinine level before and after vascular interventional therapy and at the last follow-up were compared.Results:Six pediatric kidney transplantation recipients were diagnosed as TRAS.The median operative age was 12(9-17)years, the median postoperative time to diagnosing TRAS 4(1.7-18.0)months and the median follow-up period 6.6(2.5-8.0)years.All of them received vascular interventional therapy of percutaneous transluminal angioplasty(PTA, n=5)and stent angioplasty( n=1). The serum creatinine pre-treatment with vascular interventional therapy was significantly higher than baseline serum creatinine level at discharge(200.8±88.5)vs(75.2±27.9)μmol/L, P=0.025 and decreased to(103.8±44.7)μmol/L at Month 1 post-treatment( P=0.196)and(98.7±30.2)μmol/L at the last follow-up( P=0.115). Comparing with internal diameter of grafted renal artery anastomosis site(2.6±0.6 mm)pre-treatment with vascular interventional therapy, significant changes occurred at 24 h post-treatment(3.8±0.5 mm)and at the last follow-up(4.1±0.8 mm)(all P=0.027). In addition, PSV and post PSV ratio of transplanted renal artery at 24 h post-treatment(163±45.0 cm/s, 6.5±2.2)and at the last follow-up(184.7±80.8 cm/s, 5.4±2.0)were significantly lower than that before vascular interventional therapy(356.5±77.9 cm/s, 18.0±5.8)and interlobular artery PSV was significantly higher than that before vascular interventional therapy( P=0.024, P=0.032, respectively). During follow-ups, no restenosis or thrombosis occurred in transplanted renal arteries. Conclusions:PTA or stent angioplasty for TRAS children is technically feasible with low restenosis rate and relatively satisfactory mid/long-term outcomes.
ABSTRACT
Objective:To explore whether hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) preconditioning can relieve inflammation, reduce cell apoptosis and alleviate renal ischemia-reperfusion injury in mice.Methods:Male C57BL/6 mice were randomly divided into three groups of sham operation (sham), ischemia reperfusion injury (IRI) and IRI+ HIF-PHI ( n=6 each). In IRI+ HIF-PHI group, mice received an intragastric dose of roxadustat (20 mg/kg) every other day one week before. After renal IRI modeling, serum creatinine (SCr) level was monitored and hematoxylin-eosin (HE) staining employed for observing the pathological changes of renal tissue and scoring injury degree. Apoptosis of renal tubular epithelial cells was assessed by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL). Reverse transcription-polymerase chain reaction (RT-PCR) was utilized for detecting the mRNA expressions of HIF-1α, TNF-α and IL-1β in renal tissues. Immunofluorescence and immunohistochemistry were employed for detecting the expressions of hypoxia-inducing factor 1α (HIF-1α), inflammatory cytokines tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β). Results:As compared with IRI group, SCr level declined markedly in IRI+ HIF-PHI group ( P<0.01), renal tissue injury improved markedly, semi-quantitative score of renal tubule injury dropped ( P<0.01), apoptotic cells decreased ( P<0.01) and the expression levels of TNF-α and IL-1β declined ( P<0.05). Compared with sham group, the mRNA expression of HIF-1α was not significantly elevated in IRI group ( P>0.05). Immunofluorescence showed that the expression of HIF-1α in medulla of renal tissues was up-regulated in IRI group, but not markedly in cortex. While the mRNA expression of HIF-1α was markedly up-regulated after a pretreatment of HIF-PHI ( P<0.05), the expression spiked markedly in renal cortex, but was weaker in medulla than that in IRI group. Conclusions:HIF-PHI can boost the expression level of HIF-1α, reduce the expression of inflammatory factors, relieve the inflammatory response, reduce cell apoptosis, improve renal function and alleviate renal ischemia reperfusion injury.
ABSTRACT
Objective:To evaluate the effect of unilateral pediatric kidney donation for adult kidney transplantation.Methods:Retrospective analysis was conducted on the cases of children who donated unilateral donor kidney for adult kidney transplantation recipients in our hospital, and those who were followed up for more than three years were included in this study. The body weight of the recipients in group A was ≤50 kg, and the body weight of the recipients in group B was ≤70 kg.The recipients were divided into 0-5 year old donor group (group A) and 6-17 year old donor group (B group). Clinical data, recipient/kidney survival, graft function and growth, and complications of the recipient were analyzed.Results:A total of 45 adult recipients were enrolled, including 12 in group A and 33 in group B. The renal survival rate at 3 years after operation was (100%, 96.9%)/(91.6%, 93.9%). One week after the operation, the early postoperative recovery of renal function in group B was better than that in group A, and the difference of serum creatinine was statistically significant ( P<0.05), while the difference of serum creatinine in other postoperative follow-up time points was not statistically significant ( P>0.05). Within a year, both groups of grafts continued to grow, reaching adult levels in one year. There was no statistical significance in the incidence of complications between the two groups ( P>0.05). The incidence of protein in the two groups was 33.3% and 6.1%, respectively, 1 case in each group still had proteinuria at 1 year after surgery, and only 1 case in the infant donor kidney recipient in group A had proteinuria at 3 years after surgery. Conclusions:Unilateral donor kidney transplantation from children can provide good results for adult patients with uremia by selecting suitable donors according to the weight of the recipient.
ABSTRACT
Objective:To explore the effect of traditional Chinese medicine comprehensive nursing on psychological state, skin degree and quality of life in patients with rectal cancer.Methods:A total of 88 cases with rectal cancer chemotherapy in Nanyang Nanshi Hospital from August 2017 to August 2020 were as the research object, all patients were divided into two groups with 44 cases in each group by random number table method. The control group received routine nursing, the observation group was given traditional Chinese medicine comprehensive nursing based on the control group. The more satisfaction with the two groups, psychological state before and after nursing, cancer fatigue degree, the quality of life, adverse reaction after chemotherapy were compared between the two groups.Results:The satisfaction score of the observation group was (80.24±9.02) points, which was higher than that of the control group (74.64±9.02) points, there was statistically significant ( t value was 2.912, P<0.05). The probability of adverse reactions was 4.55%(2/44), which was lower than that of the control group (20.45%, 9/44), there was statistically significant ( χ2 value was 5.090, P<0.05). There were no differences in psychological state, cancer fatigue degree and quality of life between the two groups before intervention ( P>0.05). The scores of anxiety, depression, cognitive fatigue, body fatigue, emotional fatigue and behavioral fatigue after intervention were (58.24±3.56), (57.82±3.36), (5.64±1.32), (6.56±0.88), (6.04±0.64), (5.98±1.52) points in the observation group, and (60.12±3.72), (59.27±3.12), (6.28±1.48), (7.24±0.90), (6.48±0.72), (6.78±1.56) points in the control group, there were statistically significant( t values were 2.141-3.583, P<0.05).The quality of life score of the observation group after intervention was (211.68±17.12) points, which was higher than that of the control group (199.08±17.36) points, there was statistically significant( t value was 3.428, P<0.05). Conclusions:Comprehensive nursing of traditional Chinese medicine for patients with rectal cancer chemotherapy can make patients more satisfied with nursing service, relieve negative emotions and cancer fatigue, reduce the occurrence of adverse reactions to chemotherapy, and promote the improvement of patients' quality of life. It is worth popularizing.
ABSTRACT
Objective:To retrospectively analyze clinical data of infant donors with body weight ≤15 kg into children recipients, and to investigate the efficacy and complications under the strategy of pediatric donor to pediatric recipient (PTP) of pediatric kidney transplantation allocation.Methods:Clinical data of kidney transplantation for children with infant donors performed in the First Affiliated Hospital of Zhengzhou University from August 2010 to December 2019 were collected.Clinical data of donors and recipients, postoperative adverse events, postoperative renal recovery, and human and renal survival were analyzed.Results:A total of 50 infant donors and 93 pediatric recipients were enrolled in this study.Recipients included 89 patients with single kidney transplantation (SKT) and 4 with en-bloc kidney transplantation (EBKT). The major perioperative complications were delayed graft function (DGF) (5 cases, 5.4%) and vascular thrombosis (VT) (3 cases, 3.2%), followed by recurrence of primary nephropathy (3 cases, 3.2%), respiratory tract infection (3 cases, 3.2%), and acute rejection (AR) (2 cases, 2.2%). During the follow-up period, the main cause of death was respiratory tract infection (4 cases, 4.3%). Except for the cause of death, the main causes of graft loss were rejection (2 cases, 2.2%) and recurrence of primary kidney disease (2 cases, 2.2%). Serum creatinine decreased progressively from (824.77±150.24) μmol/L preoperatively to (90.73±47.24) μmol/L 1 month postoperatively.In SKT group, the median follow-up time was 31 months (3-74 months), and the survival rates of recipients and transplanted kidneys at 1, 3 and 5 years postoperatively were 97.5%/94.2%, 96%/88.8% and 93.1%/86.1%, respectively.In EBKT group, the median follow-up time was 50 months (13-65 months), and the survival rates of recipients and transplanted kidneys at 1, 3 and 5 years postoperatively were all 100.0%.During the fo-llow-up period, there was no significant difference in the human/kidney survival rate between groups (all P>0.05), and well acceptable transplantation outcomes were obtained. Conclusions:Single/double kidney transplantation for children and adolescent recipients from infant donors in the First Affiliated Hospital of Zhengzhou University has achieved acceptable outcomes.Adopted by the PTP strategy, the incidence of complications after kidney transplantation does not increase, indicating its safety and reliability.
ABSTRACT
Objective:To evaluate the time-zero biopsy of donor kidney with acute kidney injury(AKI)in organ donation donors and examine the clinical effect after transplantation.Methods:From May 2019 to May 2020, clinical data were retrospectively reviewed for 104 donors assessed by time-zero biopsy at First Affiliated Hospital, Zhengzhou University.According to the definition of AKI and Banff2016 criteria, the kidneys of 104 donors were grouped and evaluated for transplantation.And the post-transplantation effects of donor kidneys with different degrees of pathological changes were analyzed.Results:AKI occurred in 32/104 donors.Compared with non-AKI donors, statistically significant differences existed in degrees of renal interstitial fibrosis and acute renal tubular injury ( P<0.05). However, there were no significant differences in other pathological manifestations ( P>0.05). In AKI group, kidneys of 2 donors with Banff score>3 were abandoned; in non-AKI group, among 12 donors with Banff score>3, 1 donor kidney was abandoned due to a high degree of chronic diseases.No significant inter-group difference existed in creatinine value or estimated glomerular filtration rate(eGFR)( P>0.05). AKI group had a higher incidence of postoperative delayed graft function(DGF)and longer duration.There was no statistical significance in other complications ( P>0.05). Conclusions:AKI donor kidneys with pathological manifestations below moderate renal tubular injury and Banff score<3 are feasible for transplantation.Although renal function recovery is slow after transplantation, safe outcomes may be obtained.
ABSTRACT
Objective:To compare the efficacy of single kidney transplantation for children from pediatric donors between body weight ≤15 kg and >15 kg.Methods:A retrospective review in 156 children with single donor kidney transplantation from August 2010 to December 2019 in the Kidney Transplantation Department of the First Affiliated Hospital of Zhengzhou University was conducted. The patients were classified into the small kidney group (pediatric donor body weight ≤15 kg) and the big kidney group (pediatric donor body weight >15 kg). In this study, 89 cases were concluded in the small kidney group and 67 cases were concluded in the big kidney group. The donor kidneys were obtained from 46 cases of small weight (≤15 kg) pediatric donors and 48 cases of large weight (>15 kg) pediatric donors. There were significant differences in age [1.00 (0.02 - 4.00) years vs. 10.00 (3.00-18.00) years], body weight [10.0 (3.4 - 15.0) kg vs. 35.0 (16.2- 35.0) kg], height [76 (50- 113) cm vs. 144 (67-172) cm], GFR [(31.50±7.46)ml/min vs. (36.79±7.00) ml/min], and renal length to diameter [(5.91±0.48) cm vs. (8.71±1.88) cm] between the small kidney group and the big kidney group ( P < 0.01). There was no significant difference between the two groups of donors in gender, cold/warm ischemia time and cause of death ( P>0.05). There were significant differences in age [(11.28±3.89) years vs. (13.86±3.56) years], body weight [(31.83±10.45)kg vs. (35.13±9.15) kg], and height [(130.02±28.56) cm vs. (143.97±16.59) cm] between recipients of the small kidney group and big kidney group ( P < 0.05). While there were no significant differences in preoperative serum creatinine level [(822.65 ± 135.04) μmol/L vs. (777.31 ± 165.40) μmol/L], HLA mismatch [(3.4 ± 1.4) site vs. (3.2±1.3) site], and primary disease between the two groups ( P > 0.05). The recovery of renal function, postoperative adverse events, postoperative children, and graft survival were compared between the two groups. Results:The renal function of the two groups of recipients returned to normal 3 months after operation. The perioperative complications in the small kidney group and the big kidney group mainly included renal delayed recovery [5.6% (5/89) vs. 7.5% (5/67), P=0.89], renal vascular embolization [3.4% (3/89) vs. 0, P=0.35], and acute rejection [2.2% (2/89) vs. 4.3% (3/67) , P=0.75]. The main cause of recipient death during the follow-up period was pulmonary infection [4.5% (4/89) vs. 6.0% (4/67) , P=0.68]. The postoperative small kidney group was followed up for an average of 30 (3-74) months. The survival rates of children in the small kidney group at the 1, 3 and 5 years after surgery were 96.6% (86/89), 91.0% (81/89) and 91.0%(81/89), while the transplanted renal survival rates were 92.1% (82/89), 86.5% (77/89) and 84.2% (75/89), respectively. The postoperative big kidney group was followed up for an average of 32 (4-89 ) months. The survival rates of children in the big kidney group were 95.5% (64/67), 94.0% (63/67) and 91.0%(61/67) in the first 1, 3 and 5 years postoperatively, while the graft survival rates were 92.5% (62/67), 83.6% (56/67) and 83.6% (56/67), respectively. The postoperative kidneys of two groups were fast-growing, and there was no significant difference between the small kidney group and the big kidney group in graft length to diameter [(9.63±0.31) cm vs. (9.75±0.71) cm] after 1 year ( P>0.05). Conclusions:The effect of single pediatric kidney transplantation for pediatric donor with body weight ≤15 kg is equivalent to that for pediatric donor with body weight >15 kg , which can be carried out clinically.
ABSTRACT
Objective:To investigate the difference of curative effect between zero-profile bridge-shaped locking cage (ROI-C) and anterior cage combined with titanium plate fixation in the treatment of two-level and three-level cervical spondylotic myelopathy.Methods:A total of 85 patients (43 males and 42 females), aged 52.3±8.0 years (range from 28 to 66 years) with bi- and three-level cervical spondylotic myelopathy who received surgical treatment from June 2017 to October 2019 were retrospectively analyzed. There were 63 cases of two levels and 22 cases of three levels. 45 cases were treated with zero-profile bridge-shaped locking cage ROI-C (ROI-C group), and 40 cases with anterior cage combined with titanium plate fixation (titanium plate group). The main observation indicators include operation time, intraoperative blood loss, cervical Cobb angle, fusion segment Cobb angle, average intervertebral height, pain visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) Score and neck disability index (NDI).Results:All of 85 patients were followed up for 16.9±2.0 months (range 12 to 22 months). The operation time of two-level ROI-C group was 110.37±8.25 min, which was shorter than 139.5±10.54 min of titanium plate group; the intraoperative blood loss was 15.74±8.10 ml, which was less than 23.71±9.70 ml of titanium plate group; the operation time of three-level ROI-C group was 130.00±5.70 min, which was shorter than 162.83±5.59 min of titanium plate group, while the difference in the intraoperative blood loss between the two groups had no statistical significance. One year after operation, Cobb angle of cervical vertebra in double and three-level ROI-C groups were 15.31°±1.55° and 15.20°±0.42°, respectively, which were largerthan 11.23°±2.03° and 9.20°±1.14° before operation; in titanium plate group, they were 15.89°±1.13° and 16.08°±1.88°, which were higher than 11.25°±2.01° and 9.00°±1.60° before operation, and the differences had statistical significance. The differences between the two groups before operation and 1 year after operation had no statistical significance. One year after operation, the VAS scores of double and three-level ROI-C groups were 1.83±0.66 points and 2.60±0.52 points, respectively, which were less than the preoperative 7.49±0.51 points and 7.60±0.52 points; the titanium plate group was 1.79±0.50 points and 2.41±0.51 points, which were less than the preoperative 7.61±0.63 points and 7.42±0.52 points, and the differences had statistical significance. There was no significant difference between the two groups before operation and 1 year after operation. One year after operation, the JOA scores of double and three-level ROI-C groups were 15.00±0.84 points and 14.70±0.95 points, respectively, which were higher than the preoperative 7.20±0.87 points and 6.60±1.27 points; the scores of titanium plate group were 15.29±0.85 points and 14.83±0.58 points, which were higher than the preoperative 6.89±1.03 points and 6.92±0.67 points, and the differences had statistical significance. The differences between the two groups had no statistical significance. The postoperative JOA improvement rate was excellent. Postoperative dysphagia occurred in 1 case (2.22%, 1/45) in ROI-C group and 8 cases (20.00%, 8/40) in titanium plate group, and the difference in the incidence rate between two groups had statistical significance ( χ2=5.32, P=0.02). Conclusion:Both ROI-C and anterior cage combined with titanium plate fixation in the treatment of double and three-level cervical spondylotic myelopathy can achieve good short-term clinical efficacy, with shorter operation time and lower incidence rate of postoperative dysphagia using ROI-C.
ABSTRACT
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China. Unfortunately, most of HCC patients were diagnosed at the intermediate or advanced stage, losing the chance to receive the surgical intervention. Locoregional interventional treatment is one of the major therapeutic options for inoperable HCC treatment and prolongs the survival of the patients. Evaluation of the efficacy of the treatment is the important to determine the further therapy strategies. Currently, the evaluation of patients’ response is mainly based on CT and MR anatomic morphological images, but characteristics of tumor biology changes can be observed earlier than the morphological changes. In the recent years, with the development of diffusion weighted imaging (DWI), its value in clinical application has been continuously explored, and it has been increasingly used for quantitative evaluation the diffusion of water molecular and microcirculation perfusion of blood flow in tumor tissue, with some progress in evaluating the tumor response. This paper mainly reviewed the recent research findings of DWI on locoregional interventional treatment for HCC, thereby providing guidance on clinical practice.
ABSTRACT
Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
ABSTRACT
Objective:To explore the efficacies of single-center pediatric transplantations and discuss the current problems.Methods:From July 2007 to September 2019, the clinical data of 202 children (aged ≤17 years) undergoing renal transplantation were reviewed. And their perioperative complications, transplantation outcomes and patient/kidney survival were analyzed.Results:The most common perioperative complication was delayed graft function (DGF)( n=24, 11.9%), recurrence of renopathy ( n=8, 4.0%) and acute rejection ( n=21, 10.4%). The major causes of death and graft failure were lung infection ( n=9, 4.5%) and rejection ( n=11, 5.4%). Perioperative serum creatinine decreased progressively from (816.1±303.1) μmol/L preoperatively to (62.7±20.6) μmol/L at Month 3 post-operation. The value of eGFR were (166.8±37.3), (135.1±29.0) and (109.9±31.1) ml/(min·1.73 m 2) at Year 1/3/5 post-operation respectively. The survival rates were 96.7%, 96.3%, 94.1%, 93.5%, 94.1% and 90.7% at Year 1/3/5 post-operation respectively. No difference existed in human/kidney survival rate between LD and DD groups at Year 1/3/5 post-operation ( P>0.05) and transplantation outcomes were excellent. Conclusions:Effective and successful outcomes have been achieved at our center. And further optimizations are required for resolving various problems.
ABSTRACT
Objective:To study the predictive value of pretreatment apparent diffusion coefficient (ADC) on prognosis in patients with isolated large hepatocellular carcinoma(SLHCC) treated by combined transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA).Methods:A retrospective analysis was performed on 40 patients with SLHCC who were treated at the Department of Interventional Radiology, the First Medical Center of PLA General Hospital from December 2014 to July 2018, with combined TACE and RFA. There were 34 males and 6 females, with an average age of 55.9 years. All patients underwent enhanced abdominal MRI within 1 week before and 1 month after treatment. The receiver operating characteristic (ROC) curve was used to assess the predictive efficacy value of ADC. The survival curves were plotted by the Kaplan-Meier method and compared with the log-rank test. Univariate and multivariate prognostic analyses were performed using the Cox proportional hazard models.Results:After treatment, there were 18 patients with complete response and 12 with partial response. The objective response rate was 75.0% (30/40). The area under ROC curve of ADC in predicting the effectiveness of TACE combined with RFA (complete response + partial response) was 0.86 (95% CI: 0.74-0.98). The optimal threshold was 1.32×10 -3 mm 2/s, the sensitivity was 0.63, and the specificity was 1.00. The progression-free survival rate and cumulative survival rate in the high ADC group (≥1.32×10 -3mm 2/s, n=19) were better than that in the low ADC group (<1.32×10 -3mm 2/s, n=21), with significant differences (both P<0.05). On multivariate analysis, ADC<1.32×10 -3mm 2/s ( HR=3.711, 95% CI: 1.705-8.074; P<0.05) was an independent risk factor for progression-free survival, while ADC < 1.32×10 -3mm 2/s ( HR=3.518, 95% CI: 1.016-12.185, P<0.05) was an independent risk factor for overall survival. Conclusion:Preoperative ADC was an independent risk factor for prognosis in patients with SLHCC undergoing TACE combined with RFA. It has value in prognostic prediction.
ABSTRACT
OBJECTIVE@#To analyze the accuracy and positive rate of ultrasound-guided fine-needle aspiration (US-FNA) cytology for detecting suspected thyroid cancer nodules of different sizes.@*METHODS@#A total of 591 patients with 594 suspected malignant thyroid nodules received examinations with US-FNA cytology. Based on their size, the nodules were divided into group I (4-5 mm), group II (6-10 mm), group III (>10 mm). With the results of pathology as the standard, we analyzed the results of US-FNA cytology for detecting thyroid carcinoma in terms of its accuracy, indeterminate rate, positive predictive value and negative predictive value for nodules of different sizes.@*RESULTS@#The positive rates in group I, group II and group III were 39.2% (40/102), 48.2% (172/357) and 65.2% (88/135), respectively, similar between groups I and II (=0.107) and differed significantly between groups I and III (=0.000) and between groups II and III (=0.001). The accuracy, indeterminate rate, positive predictive value and negative predictive value in the 3 groups were 95.5% (21/22), 97.1% (100/103), and 94.4% (51/54); 2.9% (3/102), 2.8% (10/357), and 1.5% (2/135); 100%, 100%, and 98%; 66.7%, 57.1%, and 33.3%, respectively, showing no significant differences among the 3 groups.@*CONCLUSIONS@#The size of the thyroid nodules can affect the positive rate but does not have significant effects on the accuracy, indeterminate rate, positive predictive value or negative predictive value of US-FNA cytology.

Objective@#To explore the degree of social support in patients after Coronary Artery Bypass Grafting(CABG) and its influence on Acute Stress Disorder (ASD), in order to provide theory evidence for nursing intervention.@*Methods@#From June 2017 to Mar 2018, 359 patients after CABG in Tangshan Workers Hospital were recruited for the study. Their general information were collected, SASRQ, SSRS and PSS-Fa were used for professional evaluation.@*Results@#The degree of social support in patients after CABG was at medium level, the total score of social support was (41.69±0.28), higher than the normal domestic value[(34.56±3.73)score, n=128]; character (F=29.652), employment (t=6.526)and the type of health insurance (F=20.547)impacted on the degree of social support (P<0.05). Total score of social support had negative correlation with SASRQ total score (r=-0.528, P<0.05); character (β=0.262), family support (β=-0.281) and social support (β=-0.267) were picked in the regression equation (P<0.05), the results showed that introversion was a risk factor for ASD in patients after CABG, high degree of family support and social support were protective factors for ASD in patients after CABG.@*Conclusions@#Social support of patients after CABG needs to be improved, so as to reduce the incidence of acute stress disorder.
ABSTRACT
Objective@#To investigate the clinical effect of percutaneous curved vertebroplasty in the treatment of thoracolum-bar osteoporotic vertebral compression fractures (OVCFs).@*Methods@#All of 85 patients with single thoracolumbar vertebral OVCFs who met the admission criteria from January 2017 to July 2018 were divided into three groups according to the random dig-its table method. They were treated with percutaneous curved vertebroplasty, routine unipedicular PVP and routine bipedicular PVP respectively. There were 25 patients in the percutaneous curved vertebroplasty group, 6 males and 19 females; aged 56-80 years, with an average age of 70.6±9.7 years. Fracture vertebral body distribution: T10 2 cases, T11 4 cases, T12 3 cases, L1 9 cases, L2 3 cases, L3 1 case, L4 1 case and L5 2 cases. There were 32 patients in the routine unipedicular PVP group, 6 males and 26 fe-males; aged 58-75 years, with an average age of 69.5±9.3 years. Fracture vertebral body distribution: T10 2 cases, T11 4 cases, T12 5 cases, L1 11 cases, L2 6 cases, L3 1 case, L4 1 case and L5 2 cases. There were 28 patients in the routine bipedicular PVP group, 5 males and 23 females; aged 59-81 years, with an average age of 69.8±8.8 years. Fracture vertebral body distribution: T10 2 cases, T11 4 cases, T12 4 cases, L1 10 cases, L2 4 cases, L3 1 case, L4 1 case and L5 2 cases. The operation time, injected cement volume, in-traoperative blood loss were recorded and analyzed. Preoperative, postoperative 1 week and 3 months visual analogue scale scores and oswestry disability index were adopted to value the clinical improvements. Preoperative, postoperative 1 week and 3 months relative vertebral height and kyphosis correction, and the cement leakage rate were measured and analyzed.@*Results@#There was no significant difference in the data of gender, age, VAS scores, ODI and distribution of fracture vertebrae among the three groups (P>0.05), and the baseline data was comparable. The average VAS score in the percutaneous curved vertebroplasty group was 2.3±0.5 at 1 week after surgery, that of the routine unipedicular PVP group was 2.4±0.4 and that of the routine bipe-dicular PVP group was 2.4±0.4; the average ODI in the percutaneous curved vertebroplasty group was 19.8%±3.9%, that of the routine unipedicular PVP group was 20.0%±4.1% and that of the routine bipedicular PVP group was 19.9%±3.8%; they were lower than the preoperative data, which were statistically significant (P<0.001). The average relative vertebral height in the percutaneous curved vertebroplasty group was 48.99%±9.23% at 3 months after surgery, that of the routine unipedicular PVP group was 47.11%±10.12% and that of the routine bipedicular PVP group was 46.71%±11.16%; the average kyphosis cor-rection in the percutaneous curved vertebroplasty group was 6.21%±1.94%, that of the routine unipedicular PVP group was 5.22%±2.07% and that of the routine bipedicular PVP group was 5.97%±2.09%; there was 1 cement leakage case in the per-cutaneous curved vertebroplasty group; those of the routine unipedicular PVP group were 4 cases and those of the routine bipe-dicular PVP group were 6 cases; there was no significant difference among the three groups (P>0.05). Operation time 39.10±2.00 min vs 38.70±1.70 min, injected cement volume 3.60±0.11 ml vs 3.50±0.13 ml and blood loss 5.10±0.30 ml vs 5.00±0.40 ml of the percutaneous curved vertebroplasty group and the routine unipedicular PVP group were less than those of the routine bipedicular PVP group, which were statistically significant (P<0.05).@*Conclution@#Percutaneous curved vertebroplasty could achieve satisfactory clinical outcomes for OVCFs, with advantages of less operation time, less blood loss, limited X-ray expo-sure, less injected cement volume, and more balanced augmentation for stabilization of the affected vertebrae and total verte-bral column.
ABSTRACT
Objective@#To explore the evaluations and recipient selection methods of extended criteria donor (ECD) kidney donation in the death of citizens and analyze the transplantation outcomes.@*Methods@#From January to September 2019, the clinical data of donor-recipients were retrospectively studied. The recipients of ECD donor kidneys not evaluated for kidney zero puncture assessment from January 2014 to July 2016 were group A1 and those receiving standard donor kidney (SCD) belonged to group A2. From August 2016 to March 2019, all DCD donors were routinely evaluated for kidney zero puncture and those receiving ECD recipients fell into Group B1 and those receiving SCD belonged to Group B2. Analysis was performed for ECD/SCD donor renal zero puncture pathological features and lesion degree and utilization of ECD donor kidney; donor-recipient body surface area (BSA) ratio and lesion degree of ECD donor kidney on recipient selecting and matching. Serum creatinine value, perioperative adverse events and 1-year follow-up of human/kidney survival rate in each group were compared at 1 day, 1 week, 1 month, 3 months, 6 months and 1 year.@*Results@#A total of 108, 264, 306 and 416 recipients were recruited into A1, A2, B1 and B2 groups respectively. The ECD donor renal utilization rate was 88.5% vs 93.3% during two time periods. According to the 2016 Banff standard, glomerular sclerosis (GS), renal interstitial fibrosis (Ci) and intimal fibrosis thickening (Cv), small arterial intimal hyalinization (ah), tubular atrophy (ct) and acute tubular injury (ati) accounted for more than B1 group than B2 group (P<0.05). The severity of ECD donor kidney disease, BSA ratio <1.1 group and ≥1.1 group 1 week, 1 month, 3 months postoperative blood creatinine value was lower than the former while declining amplitude of blood creatinine was higher. A significant difference existed in the degree of moderate lesions in donor kidney (P<0.05). After 1 year, serum creatinine value of B1 group was lower than that of A1 group (P<0.05).@*Conclusions@#The quality of ECD donor kidney is obviously inferior to that of SCD donor kidney. The Banff donor kidney criterion is an effective mode of evaluating the quality of ECD donor kidney. Based upon the extent of Banff's nephropathy, the ratio of donor/recipient BSA is an important selecting method for ECD donors to receive kidneys and recipients, ultimately improving graft utilization and recipient transplantation.
