ABSTRACT

This report described one case of applying liver transplantation (LT) in for liver metastases of unresectable rectal cancer.The recipient had multiple intrahepatic metastases upon a diagnosis of colorectal cancer.FOLFOX chemotherapy plus bevacizumab targeted therapy were offered after a resection of primary lesion.Two years later, intrahepatic metastases expanded while no extrahepatic metastasis or in situ recurrence was noted.After LT, tacrolimus + sirolimus immunosuppression regimen and chemotherapy of rhatitrexed were prescribed.Tumor recurred at 3 years after LT and the survival time was 6 years.For patients with unresectable liver metastases of colorectal cancer, LT in the absence of orthotopic recurrence and other distant metastases may improve patient quality-of-life and achieve better outcomes.

ABSTRACT

Objective:To explore the feasibility and safety of robotic-assisted living donor left lateral segmentectomy (LDLLS) in a large pediatric liver transplant program.Methods:Retrospective analysis was performed for clinical data of 45 LDLLS donors and recipients from June 2021 to September 2022.Traditional open donor liver resection (n=30) and robotic-assisted segmentectomy (n=15) were performed.Two groups were compared with regards to operative duration, intraoperative hemorrhage, postoperative healing and postoperative complications.SPSS 21.0 was utilized for statistical analysis.Independent sample T, paired sample T, Wilcoxon rank sum and Chi-square tests were performed for examining the inter-group differences.Results:Operative duration of robot-assisted surgery group was substantially longer than that of traditional open surgery group ( P<0.001). Intraoperative blood loss was less in robot-assisted surgery group was less than that in traditional open surgery group[(106.0±39.8) vs.(251.0±144.8) ml, P=0.001]. Postoperative hospital stay of robot-assisted surgery group was shorter than that of traditional open surgery group[6.0(6.0, 6.0) vs.7.0(6.0, 9.0), P<0.05]. Two cases of postoperative biliary leakage were observed in donor of traditional open surgery group.Among 2 cases of abdominal infection, one was due to biliary leakage from liver section and secondary surgery was then performed.One case of incisional infection and another case of thrombosis occurred in donor of traditional open surgery group.In robot-assisted surgery group, only one donor had amylase elevation.In traditional open surgery group, there were one case of local thrombosis in middle hepatic vein and one case of bile duct stricture.No long-term complications occurred in robot-assisted surgery group during a follow-up period of over 6 months.Finally recipient data analysis indicated that no significant inter-group differences existed in operative duration, intraoperative blood loss, postoperative hospital stay or postoperative abdominal infection ( P=0.634, P=0.180, P=0.86 and P=0.153). Conclusions:Robotic-assisted LDLLS proves to be be a safe and reliable option for living donor segmentectomy.It is superior to conventional LDLLS in terms of shorter hospital stay, less intraoperative blood loss and fewer postoperative complications.

ABSTRACT

Objective:To explore the relationship between serum lactate level and early prognosis after liver transplantation (LT) in children.Methods:Between January 1, 2018 and December 31, 2020, 675 pediatric LT recipients were recruited. Clinical data were retrospectively reviewed, early postoperative serum lactate level and clearance rate recorded and receiver operating characteristic (ROC) curve plotted for determining optimal cut-off values. The inter-group differences in early postoperative complications and patient/graft survival rates were compared.Results:According to ROC, blood lactate levels >1.99 mmol/L at 12 h postoperatively were associated with early postoperative graft loss (AUC 0.73, 95% CI: 0.62-0.84, P=0.01). Age and weight of recipients in high-level group were 7.17(5.70-10.40) month and 7.00(6.00-8.60) kg and both were significantly lower than those in low-level group [7.80(6.21-13.58) month and 7.20(6.45-9.00) kg]. The inter-group differences were statistically significant ( P=0.017, P=0.034). Blood plasma transfusion volume, red blood cell transfusion volume, portal vein pressure pre-closure, postoperative intensive care unit (ICU) stay, ventilator use time, early allograft dysfunction rate, early postoperative pulmonary infection rate and recipient mortality rate in high-level group were 400 (200-400) ml, 2.00 (2.00-4.00) U, (15.71±4.44) mmHg, 2.50(2.00-3.00) day, 3.81(2.47-8.50) hour, 22.95%(42/185), 16.76%(31/185) and 6.49%(12/185) respectively. The above values were significantly higher than those in low-level group 200(100-400) ml, 2.00 (2.00-3.00) U, (14.69±4.68) mmHg, 2.00(2.00-3.00) day, 3.53(2.34-6.12) hour, 14.69%(72/490), 11.02%(54/490) and 1.43%(7/490) respectively. The inter-group differences were statistically significant ( P<0.001, P=0.014, P=0.015, P=0.037, P=0.043, P=0.011, P=0.045 & P<0.001). The incidence of early postoperative acute cellular rejection was significantly lower in high-level group than that in low-level group [11.89%(22/185) vs 22.86%(112/490)]. The inter-group difference was statistically significant ( P=0.01). The 1/3-month cumulative survival rates of patient/graft were 94.6%, 94.1% and 92.4%, 91.4% in high-level group versus 99.2%, 98.6% and 99.0%, 98.4% in low-level group. There were significant inter-group differences ( P=0, P<0.000 1). With a rising level of lactate at 12 h postoperatively, risk of early graft loss and early recipient mortality spiked markedly ( P<0.05). Conclusions:Serum lactate level post-operation is a valid predictor of early prognosis after LT in children.

ABSTRACT

Objective:To explore the effects of frailty syndrome on activities of daily living and its associated risk for adverse outcomes among elderly residents in China.Methods:Using open data from "China Health and Retirement Longitudinal Survey", the 2011 baseline survey was conducted on general information, health risk factors, chronic disease, data obtained from various ability assessments and Fried frailty criteria assessments for community elderly aged 60 years and over.The follow-up data were used to analyze the adverse outcomes of frailty syndrome using a covariation-adjusted Logistic regression model.Results:Among the 5 630 people in the baseline population, 34.9%(1 963/5 630 cases)were non-frailty, 57.4%(3 236 cases)were pre-frailty, and 7.7%(431 cases)were frailty.The frailty group had higher rates of falls, hip fractures, hospitalizations, and death than the pre-frail and non-frail groups at the 3rd, 5th, and 8th years of follow-up.At follow up to 2015, the covariate-adjusted analysis of the study population showed that as compared with the non-frail group, the frail group had increased risks of falling( OR=1.738, 95% CI: 1.292-2.338, P<0.001), increased risks of hip fracture( OR=2.672, 95% CI: 1.365-5.233, P=0.004), increased risks of hospitalization( OR=1.670, 95% CI: 1.224-2.277, P=0.001), increased risk of death( OR=1.599, 95% CI: 1.256-2.035, P<0.001), increased risks of declined upper limb activity( OR=2.769, 95% CI: 2.101-3.650, P<0.001), of declined instrumental activity of daily living( OR=2.567, 95% CI: 1.941-3.395, P<0.001), and of declined basic activities of daily living( OR=2.790, 95% CI: 2.110-3.689, P<0.001). Conclusions:Frailty syndrome increases the risk of decreased ability to live, falls, hip fractures, hospitalization and death in older adults.Frailty screening is an effective tool for predicting the risk of adverse outcomes in elderly community populations.

ABSTRACT

Objective:To explore the relationship and underlying mechanism between exosomes derived from doxorubicin-resistant osteosarcoma cells and MDR1 and miRNAs. Methods:MG63 and U2OS cell lines were selected to construct doxorubicin-resistant strains, and the 50% inhibitory concentration (half maximal inhibitory concentration, IC 50) of drug-resistant and sensitive strains was detected by MTT, and fluorescence staining was performed at intervals of 15 min between 15 and 120 min to detect the change of fluorescence intensity. RT-PCR and Western Blot were used to detect the expression levels of MDR1 P-gp to verify the drug resistance of osteosarcoma cells. Exosomes were identified by particle size analysis and Western Bolt detection. The endocytosis of PKH26-labeled exosomes from doxorubicin-resistant cells was observed, and the proliferation level and migration of exosomes from doxorubicin-resistant cells co-cultured with osteosarcoma cells were detected by MTT assay and cell scratch assay. The differential expression levels of miRNAs in osteosarcoma-sensitive and drug-resistant cells were verified by sequencing and bioinformatics analysis and RT-PCR assay. Tumor growth, serum exosome identification and mRNA expression level of miR-21-5p in tumor-bearing nude mice between normal osteosarcoma cell group and drug-resistant group, drug-resistant+normal exosome group, drug-resistant+drug-resistant+drug-resistant exosome group were observed. MDR1 expression level in tumor tissue was detected by RT-PCR, Western Blot and immunohistochemistry. Results:The IC 50 of two adriamycin resistant strains were 2.21 vs. 11.81 μg/ml and 0.93 vs. 11.81 μg/ml, respectively, and the fluorescence intensity decreased faster than that of normal strains. The relative mRNA expression levels of MDR1 in two cell lines were normal 1.12±0.16, 1.02±0.11 and drug-resistant 2.15±0.10, 2.127±0.12, respectively. The relative protein expression of P-gp was normal 0.92±0.11, 0.73±0.10 and drug-resistant 0.46±0.03, 0.30±0.04, the differences were statistically significant ( P<0.05). Drug-resistant exosomes can enter osteosarcoma cells through endocytosis and concentrate in the cytoplasm when co-cultured with normal strains. Osteosarcoma cells were co-cultured with drug-resistant exosomes at 2, 4, 6, and 8 μg/ml adriamycin, respectively. Compared with normal group, the proliferation level in drug-resistant group was significantly increased. Compared with the normal cell group 35.95±3.92, 6.72±3.55 and the normal exosome group 51.22±5.55, 19.31±1.93, the drug-resistant cell group 54.20±9.32, 19.24±2.88 and drug-resistant exosome group 76.40±5.41, 30.26±4.87, all had significantly higher cell mobility, the difference was statistically significant ( P<0.05). Exosome sequencing and biogenic analysis of 10 highly upregated miRNAs to validate mRNA expression differences between normal and drug-resistant strains by RT-PCR, showing a significant increase in miR-21-5p expression level of drug-resistant strains (5.89±0.26 vs. 0.99±0.06; 1.05±0.07 vs. 8.80±0.93, P<0.05), the difference was statistically significant ( P<0.05). In MG63 and U2OS, the normal cell group and drug-resistant cell group, and the normal exosome group and drug-resistant exosome group were compared, the tumor volume and the terminal tumor weight of nude mice were increased to varying degrees. MRNA relative expression levels of miR-21-5p in serum exosomes of nude mice after drug intervention were 0.86±0.07 and 0.86±0.05 in normal cell group, respectively. The values were 1.13±0.12, 1.14±0.12 in drug-resistant cell group, 0.71±0.05, 0.75±0.03 in normal exosome group, and 0.90±0.07, 0.93±0.04 in drug-resistant exosome group. Compared with normal and drug-resistant strains, the expression levels of normal and drug-resistant exosome groups were increased, with statistical significance ( P<0.05). Conclusion:The exosomes of drug-resistant cells in osteosarcoma could enhance the proliferation level and migration ability of cells through intercellular transfer of MDR1 and miRNAs. The expression of MDR1 and miR-21-5p in drug-resistant cells and tumor-forming nude mouse serum and tumor tissues were up-regulated which suggested that it might be involved in regulating the drug resistance process of osteosarcoma.

ABSTRACT

Objective:To analyze the frequency and characteristics of polymyositis (PM) in idiopathic inflammatory myopathy (IIM), and to investigate whether PM is over-diagnosed.Methods:Patients diagnosed as IIM according to the Bohan & Peter criteria of IIM hospitalized in the Department of Rheumatology of China-Japan Friendship Hospital from 2008 to 2019 were involved in the study. Definite PM (dPM) was defined as typical clinical and pathological features including elevated creatine kinase (CK) level, muscle weakness and muscle biopsy findings with endomysial CD8 + T cell infiltration and expression of MHC-1 on sarcolemma. Meanwhile, dermatomyositis (DM), anti-synthase syndrome(ASS), immune-mediated necrotic myopathy(IMNM), sporadic inclusion body myositis(sIBM) and other myopathies were excluded according to the new classification criteria of IIM subtypes respectively. Statistical analysis was performed using SPSS software 24.0. The Kruskal-Wallis test and χ2 test were used to compare the clinical characteristics between the dPM group and other IIM subtypes. Results:A total of 1 259 patients with IIM including 1 015 (80.6%) DM and 244(19.4%) PM were enrolled in this study. According to the strict definition of PM criteria, only 0.5% of patients (6/1 259) in IIM could be diagnosed as dPM. Most PM patients were IMNM and ASS according to the new IIM subtypes criteria, of which 48.0% (117/244) were IMNM and 32.0% (78/244) were ASS. 66.7%(4/6) of dPM patients were women. One complicated with RA, and one was dPM overlaped with systemic sclerosis. All of them had muscle weakness, mild elevation of CK level [611(391,1 451) U/L], and were myositis-specific autoantibodies negative. Except one dPM patients who did not receive immunoregulatory therapy due to chronic obstructive pulmonary disease, the others were administrated with low or medium dose prednisone combined with or without immunosuppressive agents. After a median follow-up of (38±26) months, the muscle strength of dPM patients were improved.Conclusion:dPM is a very rare clinical subtype of IIM. PM is an over-diagnosed entity in clinical practice. Patients with dPM have mild symptoms and good outcome.

ABSTRACT

Objective:To investigate the treatment strategy for pediatric humeral supracondylar fractures with callus formation and displacement neglected for over 1 week.Methods:A retrospective analysis was made of the clinical data of 36 children who had been treated at Department of Pediatric Orthopaedics, Medical Center, The Second Affiliated Hospital, Inner Mongolia Medical University from January 2011 to January 2021 for humeral supracondylar fractures with callus formation and displacement neglected for over 1 week. There were 22 boys and 14 girls, with an age of (6.7±2.7) years (from 2.3 to 12.8 years). All fractures were Gartland type Ⅲ. The patients were divided into 2 groups according to their treatment methods: a closed reduction and percutaneous pinning (CRPP) group of 15 patients subjected to the CRPP treatment only, and a leverage group of 21 patients subjected to CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling. The 2 groups were compared in terms of operation time, fluoroscopy frequency, quality of reduction, and recovery time for elbow range of motion; the elbow range of motion, visual analogue scale (VAS), Mayo elbow performance score (MEPS) and complications were assessed at the last follow-up.Results:The 2 groups were comparable because there was no significant difference between them in the general information before operation ( P>0.05). All patients were followed up for (26.2±16.3) months (from 6 to 96 months). All the fractures obtained acceptable reduction and clinical union 4 to 6 weeks after operation. The operation time [(28.2±6.8) min] and fluoroscopy frequency [(27.0±6.0) times] in the leverage group were significantly less than those in the CRPP group [(40.8±10.8) min and (43.3±11.4) times] ( P<0.05). The CRPP group was significantly better than the leverage group in the intraoperative Baumann angle (78.1°±1.6° versus 73.7°±4.1°), lateral capitellohumeral angle (58.3°±2.6° versus 49.6°±5.2°) and horizontal rotation rate (109.5%±3.0% versus 103.2%±4.9%) ( P<0.05). The intraoperative reduction in the CRPP group was significantly closer to the normal mean value than that in the leverage group ( P<0.05). There was no significant difference in the recovery time for elbow range of motion between the CRPP and the leverage groups ( P>0.05). At the last follow-up, the Baumann angle (75.4°±2.8°) and the lateral capitellohumeral angle (53.2°±3.6°) in the leverage group were still significantly better than those in the CRPP group (78.3°±1.5° and 57.5°±2.3°) ( P<0.05). However, there was no significant difference in the elbow range of motion, VAS, MEPS or incidence of complications between the 2 groups ( P>0.05). Conclusion:To treat humeral supracondylar fractures with callus formation and displacement neglected for over 1 week in children, CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling is an efficient and accurate method, because it can lead to more satisfactory reduction than CRPP only.

ABSTRACT

Objective:To compare the efficacies of arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement in the treatment of chronic lateral ankle instability (CLAI) concomitant with fibular tendinitis.Methods:A retrospective cohort analysis was conducted on the clinical data of 31 patients with CLAI concomitant with fibular tendinitis, who were treated in Beijing Tongren Hospital, Capital Medical University between March 2019 and December 2021. The patients included 17 males and 14 females, aged 16-57 years [(32.8±9.6)years]. The anterior drawer test and talar tilt test were positive in all patients preoperatively. Diagnosis was confirmed by physical examination and MRI, and calcaneofibular ligament rupture was excluded. Eleven patients received arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement (modified Brostr?m procedure+tendon debridement group), and 20 underwent pure arthroscopic modified Brostr?m procedure (modified Brostr?m procedure group). The operation time, intraoperative blood loss and length of hospital stay were documented. The visual analogue score (VAS) in peroneal tendon area was assessed before operation and at postoperative 2, 6 and 12 weeks. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and foot and ankle outcome score (FAOS) were assessed before operation and at postoperative 6 and 12 weeks. The anterior drawer test was performed at the last follow-up. The foot and ankle ability measure (FAAM) score was assessed before operation and at the last follow-up. Postoperative wound healing and complications were also observed.Results:All the patients were followed up for 4-19 months [(11.3±3.5)months]. The operation time was (66.0±4.2)minutes in the modified Brostr?m procedure+tendon debridement group, which was significantly longer than (61.5±3.4)minutes in the modified Brostr?m procedure group ( P<0.05). There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups (all P>0.05). Compared with the preoperation, the value of VAS was significantly lowered, and the values of AOFAS ankle-hindfoot score, FAOS and FAAM score were significantly increased at different postoperative timepoints (all P<0.01). No significant differences in the values of VAS, AOFAS ankle-hindfoot score, FAOS or FAAM score were seen between the two groups before operation (all P>0.05). The value of VAS was 3.0(3.0, 4.0) points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 4.0(4.0, 4.0)points in the modified Brostr?m procedure group at 2 weeks postoperatively ( P<0.05). The value of VAS was 2.0(1.0, 3.0)points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 3.0(2.3, 3.0)points in the modified Brostr?m procedure group at 6 weeks postoperatively ( P<0.05). At 12 weeks postoperatively, there was no significant difference in the value of VAS between the two groups ( P>0.05). There were no significant differences in the values of AOFAS ankle-hindfoot score and FAOS between the two groups at 6 or 12 weeks postoperatively (all P>0.05). The anterior drawer test was negative in all patients at the last follow-up. No significant difference was seen in the value of FAAM score between the two groups at the last follow-up ( P>0.05). All incisions were healed well in the first stage after operation, without the occurrence of joint infection, impaired joint motion, nerve injury or deep vein thrombosis. Conclusions:Arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement can both improve the foot function in CLAI patients concomitant with fibular tendinitis. However, the combined treatment allows for early pain relief, without increasing the risk of complications, and can therefore contribute to a faster postoperative recovery.

ABSTRACT

Objective:To investigate the clinical efficacy of butylphthalide combined with hyperbaric oxygen therapy on post-stroke cognitive impairment in patients with acute ischemic stroke.Methods:A total of 90 patients with post-stroke cognitive impairment who were hospitalized within 72 hours of onset in Suining County People's Hospital from December 2019 to November 2020 were included in this study. They were randomly divided into a control group and an observation group ( n = 45/group). The control group was given conventional treatment and the observation group was given butylphthalide combined with hyperbaric oxygen therapy in addition to conventional treatment. The National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score were compared between the two groups before and after treatment. Results:Before treatment, there were no significant differences in the National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score between the two groups (all P > 0.05). At 14 days and 1 month after surgery, the National Institutes of Health Stroke Scale scores in the observation group were (4.02 ± 2.18) points and (3.21 ± 2.03) points, which were significantly lower than (5.21 ± 2.24) points and (4.62 ± 2.68) points in the control group ( t =2.55, 2.81, both P < 0.05). At 1 and 3 months after treatment, the Montreal Cognitive Assessment score in the observation group were (19.79 ± 5.67) points and (23.69 ± 2.67) points, which were significantly higher than (16.88 ± 5.12) points and (19.74 ± 2.29) points in the control group ( t = 2.56, 7.53, both P < 0.05). At 1 and 3 months after treatment, Activities of Daily Living scores in the observation group were (54.85 ± 5.69) points and (74.38 ± 4.98) points, which were significantly higher than (46.78 ± 6.24) points and (63.21 ± 5.24) points in the control group ( t = 6.41, 9.76, both P < 0.05). Conclusion:Butylphthalide combined with hyperbaric oxygen therapy for the treatment of post-stroke cognitive impairment in patients with acute ischemic stroke can alleviate neurologic deficits, and improve cognitive function and the ability of daily life.

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 explore the prognostic factors of patients with multiple myeloma (MM) based on nutritional status.@*METHODS@#The Controlling Nutritional Status (CONUT) score and clinical parameters at diagnosis of 203 newly diagnosed MM patients hospitalized in the department of hematology, Wuxi People's Hospital from January 1, 2007 to June 30, 2019 were analyzed retrospectively. The best cut-off value was determined by ROC curve, and the patients were divided into high CONUT group (>6.5 points) and low CONUT group (≤6.5 points); through COX regression multivariate analysis of overall survival (OS) time, CONUT, ISS stage, LDH and treatment response were selected for multiparameter prognostic stratification.@*RESULTS@#The OS of MM patients in high CONUT group was shorter. The low-risk group (≤2 points) of the multiparameter risk stratification had longer OS time and progression-free survival (PFS) time compared with the high-risk group (>2 points), and it was also effective for different age or karyotype subgroups, new drug groups containing bortezomib and transplant-ineligible subgroup.@*CONCLUSION@#The risk stratification of MM patients based on CONUT, ISS stage, LDH and treatment response is worthy of clinical application.

ABSTRACT

Stenotrophomonas species are non-fermentative Gram-negative bacteria that are widely distributed in environment and are highly resistant to numerous antibiotics. Thus, Stenotrophomonas serves as a reservoir of genes encoding antimicrobial resistance (AMR). The detection rate of Stenotrophomonas is rapidly increasing alongside their strengthening intrinsic ability to tolerate a variety of clinical antibiotics. This review illustrated the current genomics advances of antibiotic resistant Stenotrophomonas, highlighting the importance of precise identification and sequence editing. In addition, AMR diversity and transferability have been assessed by the developed bioinformatics tools. However, the working models of AMR in Stenotrophomonas are cryptic and urgently required to be determined. Comparative genomics is envisioned to facilitate the prevention and control of AMR, as well as to gain insights into bacterial adaptability and drug development.

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 risk factors of biliary complications(BCS)after pediatric living donor liver transplantation(LDLT).Methods:From January 2016 to December 2020, retrospective review of clinical data was performed for 681 children aged <18 years undergoing LDLT.There were 324 boys and 357 girls with a median age of 7.4 months and a median weight of 7.0 kg.Among 61 BCS patients(9.0%), there were biliary stricture(n=34, 5.0%), bile leakage(n=21, 3.1%)and bile leakage combined with biliary stricture(n=6, 0.9%). According to the absence or presence of BCS after LT, the recipients were divided into two groups of BCS(n=61)and non-BCS(n=620). The incidence and risk factors of BCS were analyzed.T-test, Wilcoxon rank sum test, Chi square or Fisher exact test was employed for univariate statistical analysis and Logistic regression for multivariate statistical analysis.Results:The median follow-up period was 35.5 months.Univariate analysis revealed statistically significant inter-group differences( P=0.005, 0.046, 0.009, 0.011, 0.024, 0.023, 0.004, 0.038, 0.002, 0.029, 0.023, 0.002, 0.011)in donor age[(31.4±5.7)vs.(34.3±7.5)years], time of anhepatic phase[43(37.0, 53.0)vs.47(38.8, 56.0)min], time from portal vein opening to hepatic artery opening[35(30.0, 41.0)vs. 38(30.8, 47.8)min], type of perfusion fluid, number of donor bile ducts, intestinal loop length[40(30.0, 40.0)vs.40(25.0, 40.0)cm], mode of biliary reconstruction, whether or not placing a support tube, incidence of hepatic artery thrombosis[1.6%(10/620)vs.9.8%(6/61)], incidence of abdominal infection[4.5%(28/620)vs.11.5%(7/61)], incidence of cytomegalovirus(CMV)infection[55.3%(343/620)vs.70.5%(43/61)], incidence of portal vein thrombosis[1.1%(7/620)vs.8.2%(5/61)]and incidence of pulmonary infection[19.0%(118/620)vs.32.8%(20/61)]. Multivariate analysis indicated that independent risk factors of BCS included donor age( P=0.023), number of donor bile ducts( P=0.017), time from portal vein opening to hepatic artery opening( P=0.010), hepatic artery thrombosis( P=0.004), abdominal infection( P=0.019), CMV infection( P=0.022), portal vein thrombosis( P=0.003), pulmonary infection( P=0.021)and short intestinal loop length( P=0.012). Conclusions:Biliary complications are common after pediatric LDLT.Independent risk factors are donor age, number of donor bile ducts, time from portal vein opening to hepatic artery opening, hepatic artery thrombosis, abdominal infection, CMV infection, portal vein thrombosis, pulmonary infection and short length of intestinal loop.

ABSTRACT

Objective:To investigate the effects of different donor types on the prognosis of pediatric liver transplant recipients with low-body-weight (≤6 kg).Methods:The clinical data of low-body-weight pediatric liver transplant recipients from the Department of Pediatric Organ Transplantation, Tianjin First Central Hospital from January 2013 to June 2021 were retrospectively analyzed.The recipients were divided into living donor group, split donor group and whole liver group according to the donor type.The basic information of donors and grafts, preoperative and intraoperative information of recipients, major postoperative complications and survival rates of recipients and grafts were compared.Results:A total of 244 recipients were enrolled in this study, including 183 cases in the living donor group, 18 cases in the split donor group and 43 cases in the whole liver group.There were no statistical differences in the preoperative data of the three groups, including gender, age, body weight, blood type matching, primary disease, Child-pugh grading, and pediatric end-stage liver disease score (PELD). The incidence of hepatic artery thrombosis (HAT) in the three groups was 2.2%, 16.7% and 25.6%, respectively, the difference was statistically significant between the living donor group and the split donor group ( P=0.017) as well as the whole liver group ( P<0.001). There was no significant difference between the latter two groups ( P=0.525). The median follow-up time was 37, 31 and 47 months, respectively.The 1-year and 3-year cumulative graft survival rates were 92.9%, 91.3%, 83.3% and 83.3% 76.7%, 76.7% ( P=0.016), respectively.There was statistical difference between the living donor group and the whole liver group ( P=0.004), and no statistical difference between the split donor group and the living donor group ( P=0.212) as well as the whole liver group ( P=0.610). The 1-year and 3-year cumulative recipient survival rates in the three groups were 92.9%, 91.3%, 94.4% and 94.4%, 86.0%, 86.0%, respectively, and there was no statistical difference among the three groups ( P=0.463). Multivariate analysis suggested that donor age and anhepatic phase were independent risk factors for HAT.Cold ischemia time, volume of intraoperative blood transfusion and HAT were independent risk factors for early graft loss (within 3 months). The volume of intraoperative blood transfusion and the duration of anhepatic phase were independent risk factors for recipient death. Conclusions:Living donor liver transplantation is more effective than whole liver transplantation for children with low body weight (≤6 kg). Due to the small sample size and the early exploration stage of split liver transplantation in children, the efficacy of split liver transplantation remains to be explored in clinical practice.

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

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.
