ABSTRACT
Background@#The present study investigated the regulatory effects of N6-methyladenosine (m6A) methyltransferase like-3 (METTL3) in diabetes-induced testicular damage. @*Methods@#In vivo diabetic mice and high glucose (HG) treated GC-1 spg cells were established. The mRNA and protein expressions were determined by real-time quantitative polymerase chain reaction, Western blot, immunofluorescence and immunohistochemistry staining. Levels of testosterone, blood glucose, cell viability, and apoptosis were detected by enzyme-linked immunosorbent assay, MTT, and flow cytometry, respectively. Molecular interactions were verified by RNA immunoprecipitation and RNA pull-down assay. Histopathological staining was performed to evaluate testicular injury. @*Results@#METTL3 and long non-coding RNA taurine up-regulated 1 (lncRNA TUG1) were downregulated in testicular tissues of diabetic mice and HG-treated GC-1 spg cells. METTL3 overexpression could reduce the blood glucose level, oxidative stress and testicular damage but enhance testosterone secretion in diabetic mouse model and HG-stimulated GC-1 spg cells. Mechanically, METTL3-mediated m6A methylation enhanced the stability of TUG1, then stabilizing the clusterin mRNA via recruiting serine and arginine rich splicing factor 1. Moreover, inhibition of TUG1/clusterin signaling markedly reversed the protective impacts of METTL3 overexpression on HG-stimulated GC-1 spg cells. @*Conclusion@#This study demonstrated that METTL3 ameliorated diabetes-induced testicular damage by upregulating the TUG1/clusterin signaling. These data further elucidate the potential regulatory mechanisms of m6A modification on diabetes-induced testicular injury.
ABSTRACT
Objective:To analyse the clinical features of encephalitis patients with antibodies against the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR).Methods:Three anti-AMPAR encephalitis patients diagnosed in Tangdu Hospital, the Air Force Military Medical University between January 2020 and May 2021 were retrospectively reviewed. The clinical symptoms, supplementary examination, treatment options and outcomes with knowledge from literature were summarized in this study.Results:Three patients aging from 12 to 70 years presented with symptoms ranging from cognitive impairment, personality change to headache and paralysis. The lung occupying lesion was pathologically proved to be small cell lung cancer in case 1. Antibody to AMPAR (AMPAR-ab) was positive in both blood and cerebrospinal fluid of case 1, with coexisting antibodies against sex-determining region of Y chromosome-related high mobility group box 1 in blood, and the symptoms persisted but did not recur following therapy with corticosteroids. AMPAR-ab was detected only in serum in case 2, with the lesion located in both frontal and temporal lobes, centrum semiovale and lateral ventricle, combined with classic imaging features of intracranial hypotension, and the syndrome was partially improved following treatment with corticosteroids. The lesions were located in the pons and middle cerebellar peduncle, accompanied by cerebellar atrophy in case 3. Spinal cord magnetic resonance imaging showed long hyperintense lesions involving the cervical and thoracic cord, extending from C 2 to Th 10 level on T 2-weighted images. AMPAR-ab was positive in both serum and cerebrospinal fluid. And the symptoms improved significantly following treatment with corticosteroids and intravenous immunoglobulin. Conclusions:The clinical manifestations of anti-AMPAR encephalitis are highly heterogeneous, and brainstem and spinal cord can also be involved in addition to the limbic system, accompanied by brain atrophy. Combining with concurrent antibodies, especially the intracellular antibodies, malignancy needs to be closely monitored; the immunotherapy is effective and the presence of tumor superimposed with multiple antibodies may be associated with poor prognosis.
ABSTRACT
Objective:To explore the impact of graft recipient weight ratio(GRWR)on pediatric whole liver transplantation in infants aged under 1 year.Methods:From January 2014 to December 2019, clinical data were retrospectively reviewed for 140 children aged under 1 year with whole liver transplantation.They were divided into 3 groups of low GRWR(GRWR<2.5%, 48 cases), middle GRWR(2.5%≤GRWR<5%, 73 cases)and high GRWR(GRWR≥5%, 19 cases). Basic profiles, major postoperative complications and survival rate of graft/recipient were compared.Results:There were 62 males and 78 females with an average age of (7.34±1.81)months and an average weight of(6.81±1.09)kg.The median GRWR was 3.27%(1.33%~8.12%). The higher level of GRWR, the greater age, weight and graft weight of donor in three groups and there was statistical difference ( P<0.05); operative duration, postoperative ICU stay and hospital stay were longer in low GRWR group than those in middle GRWR group and there was statistical difference( P<0.05); The incidence of postoperative hepatic artery thrombosis was higher in low GRWR group than that in middle GRWR group(31.3%vs 8.2%)and there was statistical difference( P<0.05); 4 cases of small-for-size syndrome occurred in low GRWR group, it was significantly different from the other two groups and there was statistical difference( P<0.05); the median follow-up period was(50.7±23.4)months.The survival rates of grafts at 3-month and 1/5-year were 89.6%, 91.8%, 100%; 87.5%, 87.7%, 100%; 87.5%, 87.7%, 100%and there was no inter-group difference( P>0.05). The survival rates of recipients at 3 months, 1 year and 5 years post-operation were 93.8%, 91.8%, 100%; 91.7%, 87.7%, 100%; 91.7%, 87.7%, 100%and there was no inter-group difference( P>0.05). Conclusions:Different from pediatric living donor transplantation, GRWR≥5%does not affect the survival rate of recipient/graft during whole liver transplantation.And GRWR<2.5%may boost the postoperative incidence of hepatic artery thrombosis and small liver syndrome.
ABSTRACT
Objective:To analyze clinical and immunoserological features of patients with anti-p200 pemphigoid.Methods:Clinical data were collected from patients with confirmed anti-p200 pemphigoid in Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2015 to October 2021, and their clinical and immunoserological characteristics were retrospectively analyzed.Results:Seven patients with anti-p200 pemphigoid were included. Indirect immunofluorescence on salt-split skin (IIF-SSS) showed that serum IgG antibodies of the 7 patients were located in the dermis of the salt-split skin, and Western blot analysis with dermal extracts as substrates revealed a protein band with a relative molecular mass of 200 000. Four patients presented with classic bullous pemphigoid-like skin lesions, 2 initially presented with eczematous lesions, and 1 presented with linear IgA bullous dermatosis-like skin lesions. Circulating IgG antibodies could recognize the recombinant laminin γ1 C-terminal region in 6 cases. Four patients received different doses of systemic glucocorticoids, 1 of whom was resistant to high-dose systemic glucocorticoids (equivalent to 1.4 mg·kg -1·d -1 prednisone) ; 2 responded well to minocycline and dapsone; 1 was lost to follow-up. Four patients achieved complete remission and discontinued the treatment at a mean follow-up of 22.5 months; 2 received complete remissiona on minimal therapy at a mean follow-up of 8 months. Conclusion:Patients with anti-p200 pemphigoid presented with heterogeneous clinical manifestations, and the recombinant C-terminal fragment of laminin γ1 can serve as a reliable antigen substrate for the detection of autoantibodies in patients with anti-p200 pemphigoid; some patients can eventually achieve complete remission off treatment.
ABSTRACT
Objective:To explore the clinical effect of observation and psychological intervention, splint or brace fixation as well as surgical treatment on habitual dislocation of the hip (HDH) and to combine the authors' data with a compilation of the cases from the literature, evaluingating the epidemiological characteristics of HDH and the treatment scheme to maintain the stability of hip joint by systematic literature review in children.Methods:A retrospective analysis of the relevant data of 11 patients (12 hips) with HDH were treated from March 2007 to March 2021, including 2 boys and 9 girls. The age of the first dislocation was 2.25 (1.66, 3.75) years old and 4.33 (3.33, 6.17) years old at the age of diagnosis. At the same time, the relevant literature reports were searched from 1932 to 2022, and 24 HDH patients reports and clinical studies were confirmed to be included in this study according to the inclusion and exclusion criteria. The data of 33 patients (38 hips) with HDH who were obtained in the literature, including 5 boys and 28 girls. The age of the first dislocation was 2.00 (1.50, 2.00) years old and 4.00 (2.55, 5.00) years old at the age of diagnosis. A total of 44 patients (50 hips) with HDH who were analyzed, including gender, age of first dislocation, age of diagnosis, mode of stimulating dislocation, side and direction of dislocation, accompanying symptoms, family history, trauma history and imaging examination. The data of 41 patients with HDH (3 patients were excluded due to lack of treatment description) were treated with observation and psychological intervention in 19 patients, splint or brace fixation in 13 patients, and surgical treatment in 9 patients. The femoral neck-stem angle, acetabular index, central edge angle (CE angle) and Reimers instability index were measured by AutoCAD software, and the hip function was evaluated by Harris standard. Meantime, the disappearance time of dislocation was recorded.Results:The average follow-up time of 44 patients (50 hips) with HDH were 4.05±2.93 years old, and the time of disappearance of dislocation after treatment were 1.28±1.19 years old. Patients were diagnosed as 7 boys and 37 girls, 30 right and 8 left as well as 6 bilateral, the age of the first dislocation was 2.64±1.54 years old and 4.52±2.64 years old at the age of diagnosis. The data of 39 patients took hip flexion, adduction, internal rotation or hip flexion and adduction as the mode of stimulating dislocation. There were 43 patients with posterior dislocation, 41 patients with an audible "click" sound during dislocation, 36 patients with painless dislocation, and 37 patients with "vacuum phenomenon" were captured at the moment of dislocation. All patients with HDH had no specific family history and obvious history of trauma. There was no significant difference in general data between observation and psychological intervention group, splint or brace fixation group as well as surgical treatment group ( P>0.05). Harris standard to evaluate hip function, CE angle and Reimers instability index of the affected side were significantly different from those before and after treatment at the moment of dislocation ( H=127.51, P<0.001; H=55.70, P<0.001; H=54.69, P<0.001). Compared with the immediate disappearance of dislocation in the surgical treatment group, the disappearance time of dislocation in the observation and psychological intervention group and the splint or brace fixation group were significantly longer, and the difference was statistically significant ( H=20.83, P<0.001). Conclusion:Without specific family history and obvious trauma at young girls, painless posterior dislocation of hip with an audible "click" sound and "vacuum phenomenon" at the moment of dislocation are the significant epidemiological characteristics of HDH. Observation and psychological intervention, splint or brace fixation are recommended as the initial treatment scheme. When conservative treatment is ineffective, surgical treatment is needed to stabilize the hip joint quickly.
ABSTRACT
Objective:To study the impact of donor left hepatic vein classification and the reconstruction methods on hepatic venous outflow obstruction (HVOO) after pediatric living-donor liver transplantation using left lateral liver segments.Methods:A retrospective study was performed on the clinical data of 653 children recipients who underwent living-donor liver transplantation with left lateral liver segments from January 2014 to December 2020 at Tianjin First Central Hospital. There were 309 males and 344 females, aged 7.0 (6.0, 10.0) months, with an age range of 3-121 months. Based on the left hepatic vein on preoperative donor enhancement CT as well as the intraoperative reconstruction methods, the recipients were divided into 3 groups: type Ⅰ group ( n=514), anastomosis using a single opening was performed directly between the donor and the recipient; type Ⅱ group ( n=118), angioplasty was performed on two adjacent recipient venous orifices before anastomosis, and type Ⅲ group ( n=21), an interposition vessel was anastomosed to two widely spaced openings or the two veins were anastomosed separately. The preoperative general status of the patient, postoperative HVOO incidences, and graft and recipient survival rates were compared among the three groups. The patients were followed up by outpatient reexamination or telephone. Results:Graft to recipient weight ratio in the type Ⅲ group was smaller than that in the type Ⅰ group and the type Ⅱ group ( P<0.05). For all the 653 patients, the incidence of postoperative HVOO was 4.59% (30/653), with the incidences of HVOO in the 3 groups of patients were 4.1% for the type Ⅰ group (21/514), 5.1% for the type Ⅱ group (6/118), and 14.3% for the type Ⅲ group (3/21), respectively. There was no significant difference among the groups ( P>0.05). The recipient cumulative survival rates at 1 and 3 years after surgery in the type I group were 97.8% and 97.0%, and the corresponding rates in the type Ⅱ group were 96.5% and 94.2%, and in the type Ⅲ group were 94.1% and 86.9%, respectively. There was a significant difference between the type Ⅰ and type Ⅲ groups ( P=0.048). The graft cumulative survival rates at 1 and 3 years in the type Ⅰ group were 97.4% and 96.9%, and the corresponding rates in the type Ⅱ group were 94.9% and 92.5%, and in the type Ⅲ group were 94.1% and 86.9%, respectively. The difference in the postoperative graft cumulative survival rates between the type Ⅰ group and type Ⅱ group was significant ( P=0.044). Conclusions:The anatomy of the left hepatic vein supplying the left lateral liver segment was highly variable, and the majority of the variations could be reconstructed. A reasonable reconstructive method could reduce the incidence of postoperative HVOO and improved the outcomes of the graft.
ABSTRACT
Objective Health education resource allocation is one of the basic indicators for evaluating health equity. At present, the research on the equity of health education resource allocation in China is mostly limited to a single year or regional data. This study was aimed to understand the equity of health education resources in the whole China from 2015-2019, and to provide a corresponding basis for further rational allocation of health education resources. Methods The data was obtained based on the number of health education training work, health education publicity work, distribution of health education publicity materials and the annual use of funds carried out mainly by the CDC or health education centers in each province according to the 2016-2020 China Health Statistics Yearbook. The inequality coefficient (Gini coefficient) and Lorenz curve were applied to study the selected data. Results The total number of health education resources in China from 2015-2019 was 1 789 735 and 1 933 336, respectively. The Gini coefficients of health education resource allocation by population distribution were all below the warning line of 0.4, which were in an equitable state. Conclusion The equity of health education resources in China is good according to demographic indicators, and there is no significant inequity. Especially, the aspects of health education services, such as technical consultation and media cooperation, are relatively good, but there is still much room for improvement in the construction of websites.
ABSTRACT
With the development of the knee-preservation concept and surgical techniques, lateral unicompartmental knee arthroplasty (UKA) has become an effective method for the lateral compartment osteoarthritis of the knee.The incidence of knee osteoarthritis is low in the lateral compartment, which is different from the medial compartment in anatomical and kinematic characteristics. These two factors increase the challenge of lateral UKA, so the clinical efficacy of lateral UKA has been controversial. With the improvement and renewal of treatment concepts, surgical techniques and prosthesis design, the clinical effect of lateral UKA and the survival rate of the prosthesis have been continuously optimized. This article aims to summarize the characteristics of lateral compartment knee osteoarthritis, clinical efficacy, prosthesis selection, reasons for revision, future application and prospects, combined with relevant literature in recent years, to review the current progress of lateral UKA.
ABSTRACT
Objective:To investigate the effect of the possibility of sleep-disordered breathing (SDB) as assessed by the four-variable score on the platelet function and the risk of stroke recurrence in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke admitted to the Department of Neurology, Weihai Municipal Hospital from January 2020 to January 2021 were enrolled prospectively. Main inclusion criteria: admission within 24 h of onset; National Institutes of Health Stroke Scale score ≤3; Receiving aspirin + clopidogrel dual antiplatelet therapy. All patients were divided into a high possibility group and a low possibility group of SDB according to the four-variable score. 7±2 d after dual antiplatelet therapy, PL-12 multi-parameter platelet function analyzer was used to detect the maximum aggregation rate (MAR). The patients were followed up for 6 months after discharge and the recurrence of ischemic stroke was observed. The mediating effect model was established with the high possibility of SDB as the independent variable, MAR as the intermediary variable and stroke recurrence as the dependent variable. Firstly, MAR as the dependent variable and high probability of SDB as the independent variable were analyzed by linear regression; then, a binary logistic regression analysis was performed with ischemic stroke recurrence as the dependent variable and the high probability of SDB and MAR as independent variables. Results:A total of 213 patients were enrolled in the study. The average age of the patients was 62.70 ± 10.04 years old. There were 146 male (68.5%) and 121 patients (56.8%) were in the high possibility group (56.8%). During the follow-up period, 24 patients (11.3%) had stroke recurrence. Univariate analysis showed that arachidonic acid (AA) induced MAR (MAR-AA) and adenosine diphosphate (ADP) induced the MAR (MAR-ADP) in the high possibility group of SDB were significantly higher than those in the low possibility group (all P<0.05); MAR-AA and MAR-ADP in the recurrent group were significantly higher than those in the non-recurrent group (all P<0.05), and the proportion of high possibility of SDB in the recurrent group was significantly higher ( P=0.008). Binary logistic regression analysis showed that homocysteine (odds ratio 1.132, 95% confidence interval 1.048-1.223; P=0.002) and having high possibility of SDB (odds ratio 6.351, 95% confidence interval 1.134-35.566; P=0.035) were the independent risk factors for stroke recurrence in patients treated with dual antiplatelet therapy. Intermediary effect analysis showed that MAR had a significant intermediary effect on the risk of stroke recurrence in patients with high probability of SDB. Conclusion:The MAR and stroke recurrence rates in the high possibility group of SDB were significantly higher than those in the low possibility group, and its stroke risk was probably mediated by platelet hyperreactivity.

@#Eggerthelle lenta (E. lenta) is a gram-positive non-spore-bearing anaerobic bacilli that was first isolated from human feces by Arnold Eggerth in 1935.[1] It is classified as an anaerobic eubacterium that cannot decompose glucose and tryptophan[2] but can synthesize different kinds of steroid metabolism enzymes.[3] On the basis of the high content of guanine + cytosine detected by 16S ribosomal RNA gene sequencing, its original name Eubacterium lentum was changed to E. lenta and concurrently transferred to its own distinct genus Eggerthella.[4]E. lenta often exists in the gastrointestinal tract.[5] Previous reports on E. lenta-induced sepsis were rare. Herein, we present a case of E. lenta-induced sepsis with abdominal pain as the main symptom.
ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease in the world and seriously threatens human health. So far, change in unhealthy lifestyle is still the most important treatment method for NAFLD. However, traditional lifestyle intervention depends on hospital visits and follow-up, and patients tend to have poor execution and compliance. With the help of the Internet technology, digital therapeutics overcome these disadvantages and has achieved a certain clinical effect in NAFLD patients. This article reviews the application of digital therapeutics in medicine and NAFLD treatment, so as to provide a reference for the treatment of NAFLD.
ABSTRACT
Objective:To explore the clinicalfactors related to allograft fibrosis after pediatric liver transplantation.Methods:The clinical data were respectively analyzed for 94 pediatric recipients from January 2013 to December 2016 at Tianjin First Central Hospital.The Patients were assigned into fibrotic and non-fibrotic groups based upon the results of protocol liver biopsies. Univariate and multivariate Logistic regression analyses were performed for examining the risk factors of fibrosis after pediatric livertransplantation. Then Logistic regression model was established to obtain the predicted value of combined predictive factors.Thereceiver operating characteristic curve (ROC) was conducted to evaluate the predictive value of combined predictive factors.Results:A total number of 54(57.5%) patients occurred fibrosis among the 94 patients. There weresignificant differences in cold ischemia time (Z=2.094), warm ischemia time (Z=2.421), biliary stricture( χ2=4.560), drug-induced liver injury ( χ2=7.389), hepatic artery thrombosis and rejection ( χ2=6.955)between two groups ( P<0.05). Logistic regression analysis showed that cold ischemia time (OR=1.003, 95%CI: 1.000~1.007, P=0.044), biliary stricture(OR=6.451, 95%CI: 1.205~33.295), rejection(OR=2.735, 95%CI: 1.057~7.077)and drug-induced liver injury (OR=4.977, 95%CI: 1.207~20.522, P=0.026) were independent risk factors for fibrosis 5 years after liver transplantation. The area under the ROC curve was 0.786(95%CI: 0.691~0.881), for predicting patient outcome.If using 0.311as a cutoff Value, the sensitivity was 90.70%, and the specificity was 60.00%. However, through the ROC curve comparison, there was statistical significance between combined predictive factors and the other independent risk factors ( P>0.05). Conclusions:The incidence of fibrosis 5 years after pediatricliver transplantation is 57.5%. Prolonged cold ischemia time, biliarystricture, rejectionand drug-induced liver injury after liver transplantation are independent risk factors for fibrosis 5 years after pediatric liver transplantation.And the combined predictive factors have a high predictive value forallograftfibrosis.

Extracellular matrix metalloproteinase inducer (EMMPRIN) is a cell adhesion molecule with increased expression in a variety of tumors. This study focused to clarify the specific function of EMMPRIN in bone metastasis of breast cancer. @*Materials and Methods@#Adenovirus with shRNA-EMMPRIN was transfected into MRMT-1 rat breast carcinoma cells, and the MRMT-1 cells with different expression levels of EMMPRIN were implanted into the bone marrow cavity of rat tibia. Next, the effect of down-regulation of EMMPRIN was evaluated as follows: bone damage was detected by X-ray radiological and tartrate-resistant acid phosphatase staining; the tumor burden was evaluated by hematoxylin and eosin staining; the test of pain-related behaviors was assessed used the bilateral paw withdrawal mechanical threshold; and the levels of secretory factors in tumor conditioned medium were determined by using enzyme-linked immunosorbent assay. @*Results@#We found that down-regulation of EMMPRIN in tumor cells can simultaneously reduce tumor burden, relieve cancer-induced bone destruction and pain. @*Conclusion@# @*Materials and Methods@#EMMPRIN is expected to be a therapeutic target for relieving bone metastasis of breast cancer and alleviating cancerinduced bone destruction and pain. The method of targeting EMMPRIN may be a promising strategy for the treatment of cancer in the future.
ABSTRACT
Objective To understand the prevalence of soil-transmitted nematode infections in Yancheng City from 2016 to 2020, so as to provide insights into the development of the scheme for further soil-transmitted nematodiasis surveillance. Methods Soil-borne nematode infections were detected using the modified Kato-Katz method (two slides for one sample) among the permanent residents living in Yancheng City from 2016 to 2020, and Enterobius vermicularis infection was additionally detected among children at ages of 12 years and lower using the adhesive cellophane-tape perianal swab method. The prevalence and intensity of human soil-borne nematode and E. vermicularis infections were descriptively analyzed. Results A total of 51 259 person-time residents were detected for soil-borne nematode infections in Yancheng City from 2016 to 2020, and 48 egg-positives were identified, with a 0.09% prevalence. The soil-borne nematodes infecting residents included Ascaris lumbricoides, hookworm and Trichuris trichiura, with 0.04%, 0.05% and 0.002% prevalence rates of infections, and all infections were mild. There was a region-specific prevalence of soil-borne nematode infections in Yancheng City (χ2 = 18.21, P = 0.02), with the highest prevalence seen in Funing County (0.21%), while no infections were detected in Dafeng District for five successive years. The overall prevalence of E. vermicularis infections was 0.22% among children at ages of 12 years and lower in Yancheng City. Conclusions The prevalence of soil-borne nematode infections appears a gradual decline in residents living in Yancheng City from 2016 to 2020, and is at an extremely low level. Further surveillance of soil-transmitted nematodiasis requires to be intensified targeting key regions and populations to consolidate the control achievements.
ABSTRACT
Objective:To explore the efficacy of reduced left lateral segment graft during pediatric living donor liver transplantation.Methods:From January 2014 to December 2019, 67 children aged under 1 year underwent living donor liver transplantation with reduced left lateral segment graft (RLLS group). Clinical data were analyzed retrospectively and compared with those of left lateral segmentgraft living donor liver transplantation (LLS group). The differences in basic profiles, postoperative complications and postoperative patient/graft survival rate were compared.They were divided into two groups according to whether graft/recipient weight ratio (GRWR) was more than 4%.And major postoperative complications and graft/recipient survival rates were compared.Results:Age, height and weight of recipients were significantly lower in RLLS group than those in control group ( P<0.05). However, donor weight, donor body mass index (BMI), estimated graft volume and proportion of fatty liver from donor were significantly higher than those in control group ( P<0.05). Operative duration, intraoperative blood loss and erythrocyte transfusion were significantly higher than those in control group ( P<0.05). No significant inter-group differences existed in average postoperative hospital stay, intensive care unit (ICU) stay duration or postoperative ventilator use time ( P>0.05); no significant inter-group difference existed in the incidence of such major surgical complications as hepatic artery thrombosis, portal vein stenosis and bile duct complications ( P>0.05). The 1/3-year cumulative survival rates of postoperative patients and grafts were 92.5%, 91.2% and 92.5%, 91.2% in RLLS group and 96.3%, 95.3% and 95.9%, 95.1% in LLS group respectively.There was no significant inter-group difference ( P<0.05). The rate of postoperative hepatic vein stenosis was significantly higher in GRWR>4% group than that in control group ( P<0.05). Conclusions:Due to a rapid progress of technology, living donor liver transplantation has achieved satisfactory outcomes in children with reduced left lateral segment graft.Whether or not performing reduction surgery should be judged comprehensively according to the matching of donors and recipients and blood flow of liver during operations.And GRWR>4% is not an implementation criterion.
ABSTRACT
Objective:To examine the incidence of lymphatic leakage after pediatric liver transplantation and explore the diagnosis and treatment of lymphatic leakage.Methods:From January 1, 2016 to December 31, 2019, clinical data were analyzed retrospectively for 805 pediatric liver transplant recipients. Based upon the diagnosis of lymphatic leakage, they were divided into two groups of lymphatic leakage ( n=271) and lymphatic non-leakage ( n=534). Analyzing the incidence of lymphatic leakage after liver transplantation in children, evaluating the treatment plan, comparing survival rate and the incidence of postoperative complications between two groups. Results:The incidence of lymphatic leakage was 33.7%(271/805); the proportion of partial liver donors was 14.8% in lymphatic leakage group and 25.8% in lymphatic non-leakage group ( P<0.001). Other basic profiles of two groups were not statistically different. The median follow-up period was 32 months in lymphatic leakage group and 30.6 months in lymphatic non-leakage group. No significant inter-group difference existed in cumulative survival rate, vascular complications, bile leakage, acute cell rejection or intestinal obstruction. The area-under-curve (AUC) of ascites to serum triglyceride (TG) ratio for predicting lymphatic leakage was 0.741, optimal cut-off value 0.54, sensitivity 59.2% and specificity 80.1%. Conclusions:Lymphatic leakage is a common complication after liver transplantation in children. With no significant correlation with the morbidity or mortality, it prolongs postoperative hospital stay. The ratio of ascites to serum TG may be utilized as an effective reference index for diagnosing lymphatic leakage. And lymphatic leakage can be improved by taking a low-fat diet.
