ABSTRACT

Objective:To study the early effects of intact-umbilical cord milking (I-UCM) and cut-umbilical cord milking (C-UCM) for the prevention of anemia of prematurity in preterm infants.Method:From January 2019 to October 2019, C-section delivered infants with gestational age <34 weeks were randomly assigned into I-UCM group and C-UCM group. Hematological parameters at different timepoints after birth, iron status, incidence of anemia within 7 d after birth, blood transfusions, transcutaneous bilirubin levels and the total duration of phototherapy were collected and analyzed.Result:A total of 60 cases were enrolled, including 30 in I-UCM group and 30 in C-UCM group. I-UCM group had significant higher levels of hemoglobin (Hb), hematocrit (Hct) and serum iron on admission ( P<0.05). Comparing with C-UCM group, Hb and Hct were significantly higher in I-UCM group at 7 d and 14 d after birth ( P<0.05). Lower prevalence of anemia within 1 week [3.3% (1/30) vs. 33.3% (10/30), P<0.05] and less blood transfusions during hospitalization [13.3% (4/30) vs. 56.7% (17/30)] were noted in I-UCM group. No statistically significant differences existed between the two groups in phototherapy duration and the peak bilirubin levels ( P>0.05). Conclusion:I-UCM can provide more placental transfusion at birth to increase Hb levels and iron storage to prevent and reduce anemia in preterm infants.

ABSTRACT

Objective To investigate the prevalence rate of non-obese fatty liver disease and its influencing factors, and to provide a reference for the prevention and treatment of fatty liver disease. Methods A total of 23 545 individuals who underwent physical examination in Karamay Central Hospital from January to December 2015 and had complete data of abdominal ultrasound, body mass index (BMI), age, and sex were screened out to analyze the prevalence rate of fatty liver disease, and 7484 individuals with normal BMI who had complete data of triglyceride (TG), fasting blood glucose, and alanine aminotransferase (ALT) were further screened out to perform a multivariate analysis. The t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. A multivariate logistic regression analysis was performed to investigate independent influencing factors for non-obese fatty liver disease. Results In 2015, the prevalence rate of fatty liver disease was 30.2% (7116/23 545) among the individuals who underwent physical examination in Karamay Central Hospital. A stratified analysis based on BMI showed that the individuals with emaciation, normal BMI, overweight, and obesity had a prevalence rate of 0.8% (6/706), 9.3% (919/9899), 38.4% (3404/8870), and 68.5% (2787/4070), respectively (all P 0.05), while both of them had a significantly higher prevalence rate than the young individuals (14.5%/16.8% vs 6.0%, P < 0.05). Young and middle-aged male individuals had a significantly higher prevalence rate of fatty liver disease than their female counterparts ( χ 2 =99.40 and 43.29, both P < 0.001), while the elderly male individuals had a significantly lower prevalence rate than their female counterparts ( χ 2 =9.81, P =0.002). For the individuals with normal BMI, the individuals with normal TG had a prevalence rate of fatty liver disease of 5.0% (311/6273), while those with elevated TG had a prevalence rate of 26.8% (325/1211), with a significant difference between the two groups ( χ 2 =624.90, P < 0.001). The multivariate logistic regression analysis showed that age, BMI, ALT, fasting blood glucose, TG, and serum uric acid level were independent influencing factors for fatty liver disease in individuals with normal BMI (all P < 0.001). Conclusion There is a relatively high prevalence rate of non-obese fatty liver disease among individuals undergoing physical examination in Karamay Central Hospital, and 61.5% of the patients with non-obese fatty liver disease have glucose or lipid metabolic disorders. Serum TG level may be used as a simple and effective screening index for non-obese fatty liver disease.

ABSTRACT

Objective:To investigate the effect of lateral tibial periosteum distraction on diabetic foot and vasculitis foot.Methods:A retrospective analysis of 13 patients (16 feet) who received lateral tibial periosteal distraction between June 2019 and May 2020 were included in the study. 9 males and 4 females; aged 39-77 years (average 66 years); left foot 7 cases, right foot 9 cases. 5 cases were patients with diabetic foot, 1 case was diabetic foot with arteriosclerosis obliterans, 2 cases were thromboembolic vasculitis, and 5 cases were arteriosclerosis obliterans. The tibial periosteum was dissected and a distraction device was placed. In the 3 patients with foot ulcers, tibial periosteum distraction devices were placed on the severer side. The periosteal distraction began on the third day after surgery, about 0.75 mm/d, the adjustment was done usually in two weeks. Two weeks later, the stretch plate was removed surgically. The followings were evaluated: visual analogue scale (VAS) pain score, foot peripheral oxygen saturation, foot capillary filling test, lower extremity arterial CT angiography (CTA), etc.Results:All 13 patients were followed up for 2-12 weeks, with an average of 3.85 weeks. VAS pain score: the average pain score of 13 patients with preoperative foot pain was 5.31±1.84 (range, 2-9) points, and 2 weeks after surgery, the average value was 2.46±1.39 (range, 1-6) points with statistical significance ( t=6.124, P<0.001) ; peripheral foot oxygen saturation: the average preoperative blood oxygen saturation of 12 patients was 87.83%±14.83% (range, 50%-98%), 1 patient was not detected before surgery, and 2 weeks after operation, the average blood oxygen saturation was 92.33%±7.91% (range, 75%-99%). There was no significant difference between them ( t=1.124, P=0.285). The foot skin temperature of 10 patients was 35.68±0.85 ℃ (range, 34.00-36.60 ℃) before surgery and 36.23±0.46 ℃ (range, 35.50-36.90 ℃) after surgery, and the difference was statistically significant ( t=3.197, P=0.008) . Capillary filling test: 2 weeks after operation, the capillary filling response was significantly improved. All 13 patients had improved CTA of both lower extremity arteries before operation, and 11 patients had CTA taken back after two weeks of operation. Compared with preoperative CTA, new vascular network was found in the operation limb. In addition to 1 patient with thromboangiitis obliterans (mainly suffering from foot pain, no wound symptoms), 2 of 12 patients with heart failure, renal failure and other basic diseases did not heal, and the wounds of the other 10 patients had improved significantly 1 month later. Conclusion:Lateral tibia periosteum distraction can be used to treat chronic ischemic diseases of lower extremities with satisfactory postoperative results.

ABSTRACT

Objective:To investigate the application value of superb microvascular imagingin monitoring angiogenesis in the treatment of chronic ischemic diseases of lower limbs by tibial transverse transport.Methods:From May 2019 to December 2020, 12 patients with ischemic diseases of lower limbs who received tibial transverse transport therapy were retrospectively analyzed, including 7 male patients and 5 female patients, aged 30-86 years, with an average age of 64.0±16.6 years. Among them, there were 10 patients with diabetic foot, with a disease course of 5-30 years (mean 14.4±8.3 years), and 2 patients with arteriosclerosis obliterans. The results of lower extremity superb microvascular imaging before and after treatment were recorded and compared.Results:After treatment, 12 patients were found to have obvious new vessels around the artery of lower extremity, the number of vessels 1-8, the average number of 3.25±2.73. We found that a total of 12 patients 20 inherent lower limb artery collateral established, collateral circulation was found around 12 dorsal metatarsal artery (DMA) in 11 patients, around 3 dorsal pedis artery (DPA) in 2 patients, around 3 anterior tibial artery (ATA) in 2 patients, and around 1 posterior tibial artery (PTA) in 2 patients. The lateral branches were established in ipsilateral lower limbs in 6 patients, contralateral lower limbs in 2 patients, and bilateral lower limbs in 4 patients.Conclusion:The phenomenon of angiogenesis is obvious in the clinical application of tibial transverse transport. Superb microvascular imaging can effectively reflect the degree of promoting the establishment of collateral circulation by tibial transverse transport.

ABSTRACT

Objective:To evaluate the effect of early mobilization on mortality in intensive care unit (ICU) patients with mechanical ventilation after discharge by Meta-analysis.Methods:Databases including SinoMed, China National Knowledge Infrastructure (CNKI), Wanfang data, PubMed, the Cochrane Library, Web of Science, and Embase were searched from inception to September 17th, 2020, to collect randomized controlled trials (RCT) about early mobilization on mortality of patients with mechanical ventilation in ICU after discharge, the references included in the literature were traced. The control group was given routine care, the experimental group was given early mobilization on the basis of the control group, including passive or active mobilization on the bed, sitting on the bed, standing by the bed, transferring to the bedside chair and assisting walking. The literature screening, data extracting, and the bias risk assessment of included studies were conducted independently by two reviewers. Stata 12.0 software was then used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 10 RCT studies involving 1 323 patients were included, with 660 patients in the control group and 663 patients in the experimental group. The results of literature quality evaluation showed that 7 studies were grade A and 3 studies were grade B, indicating that the overall quality of included literatures was high. The Meta-analysis results showed that early mobilization did not increase the mortality of patients with mechanical ventilation in ICU after discharge [odds ratio ( OR) = 0.92, 95% confidence interval (95% CI) was 0.75-1.13, P = 0.449]. Subgroup analysis results showed that early mobilization had a tendency to reduce the mortality of ICU patients with mechanical ventilation at 3, 6 and 12 months after discharge, but the difference was not statistically significant (3-month mortality: OR = 1.02, 95% CI was 0.74-1.40, P = 0.927; 6-month mortality: OR = 0.95, 95% CI was 0.70-1.27, P = 0.712; 12-month mortality: OR = 0.60, 95% CI was 0.33-1.10, P = 0.101). Funnel plot showed that the distribution of included literatures was not completely symmetrical, suggesting that publication bias might exist. Conclusions:Early mobilization does not increase the mortality of ICU patients with mechanical ventilation after discharge. Although it tends to have a favorable outcome in reducing mortality, and has a trend to reduce the mortality. However, due to the small number of included literatures, small sample size and differences in the specific implementation of early mobilization among various studies, a large number of high-quality RCT studies are still needed for further verification.

ABSTRACT

Objective:To analyze the clinicopathological features, treatment and prognosis of Epstein -Barr virus(EBV) positive diffuse large B cell lymphoma(DLBCL) in children, so as to improve the knowledge of pediatricians on this disease.Methods:The data of 6 cases of EBV positive DLBCL who were initially diagnosed and regularly treated in Beijing Children′s Hospital from January 2016 to December 2019 were collected, including basic information (gender, age, first symptom, and course of disease), pathological results [immunohistochemistry, EBV encoded RNA(EBER), latent membrane protein(LMP), and C- MYC gene], immune function, EBV index, treatment group, treatment plan and prognosis. Results:There were 4 males and 2 females, with the average age of 6.67 years.The uric acid was 266.2 μmol/L, lactic dehydrogenase(LDH) was 346.5 U/L at early stage, and 1 patient had immunodeficiency.The immune function test before chemotherapy indicated that the proportion of auxiliary T cells decreased in 4 cases, and the humoral immune function was normal in all patients.There was no evidence of recent infection in 6 patients, and EBV-DNA increased in 3 patients.There were 2 cases of stage Ⅲ, 4 cases of stage Ⅳ, 1 case of giant tumor, 2 cases of symptom B, 6 cases of extranodal invasion, 4 cases of central invasion and 1 case of bone marrow invasion.Three patients died and three survived.Immunohistochemistry showed that: (1) CD 19, CD 20, and CD 79a were expressed in all patients, and CD 30 was expressed in 5 patients.(2) C- MYC gene was detected by immunofluorescence in situ hybridization method in all patients, and no MYC break, Bcl-2 and Bcl-6 break and amplification were found.(3) EBV: EBER and LMP-1 were expressed in all patients. Conclusions:The pathological changes of EBV positive DLBCL are similar to those adults.The origin of non-germinal center and extranodal and central invasion are more common.The prognosis of the patients with central nervous system invasion is very poor, and the recurrence and progress of the disease often occur in the treatment or in the early stage of drug withdrawal.At present, there is no effective and feasible treatment plan.It is suggested that the patients in the late stage should receive allogeneic hematopoietic stem cell transplantation as soon as possible after intensive treatment, so as to improve the survival rate.

ABSTRACT

Objective@#To describe the characteristics of clinical manifestations and epidemiology of children with 2019 novel coronavirus (2019-nCoV) infection.@*Methods@#All 34 children with laboratory-confirmed 2019-nCoV infection by quantitative real-time reverse transcription-PCR through nasopharyngeal swab specimens were admitted to the Third People’s Hospital of Shenzhen from January 19 to Febuary 7, 2020. Clinical data and epidemiological history of these patients were retrospectively collected and analyzed.@*Results@#Among the 34 cases, 14 were males, and 20 were females. The median age was 8 years and 11 months. No patients had underlying diseases. There were 28 children (82%) related with a family cluster outbreak. There were 26 children (76%) with a travel or residence history in Hubei Province. These patients could be categorized into different clinical types, including 22 (65%) common cases, 9 (26%) mild cases and 3 (8.8%) asymptomatic cases. No severe or critical cases were identified. The most common symptoms were fever (17 cases, 50%) and cough (13 cases, 38% ). In the 34 cases, the white blood cell counts of 28 cases (82%) were normal. Five cases had white blood cell counts more than 10×109/L. One case had white blood cell counts less than 4×109/L. Neutropenia and lymphopenia was found in one case, respectively. C-reactive protein levels and erythrocyte sedimentation rates were elevated in 1 and 5 case, respectively. Elevated procalcitonin was found in 1 case and D-Dimer in 3 cases. The levels of lactic dehydrogenase (LDH) were more than 400 U/L in 10 cases. The CT images of these patients showed bilateral multiple patchy or nodular ground-glass opacities and/or infiltrating shadows in middle and outer zone of the lung or under the pleura. Twenty patients were treated with lopinavir and ritonavir. Glucocorticoids and immunoglobulin were not used in any cases. All the cases improved and were discharged from hospital. Further following up was need.@*Conclusions@#The clinical manifestations in children with 2019-nCoV infection are non-specific and are milder than that in adults. Chest CT scanning is heplful for early diagnosis. Children's infection is mainly caused by family cluster outbreak and imported cases. Family daily prevention is the main way to prevent 2019-nCoV infection.

ABSTRACT

Background@#Enteritis is one of the most frequently reported symptoms in piglets infected with porcine circovirus type 2 (PCV2), but the immunopathogenesis has not been reported. @*Objectives@#This study examined the effect of a PCV2 infection on the intestinal mucosal immune function through morphological observations and immune-related molecular detection. @*Methods@#Morphological changes within the ileum of piglets during a PCV2 infection were observed. The expression of the related-molecules was analyzed using a gene chip. The immunocyte subsets were analyzed by flow cytometry. The secretory immunoglobulin A (SIgA) content was analyzed by enzyme-linked immunosorbent assay. @*Results@#The PCV2 infection caused ileal villus damage, intestinal epithelial cells exfoliation, and an increase in lymphocytes in the lamina propria at 21 days post-infection.Differentially expressed genes occurred in the defense response, inflammatory response, and the complement and coagulation cascade reactions. Most of them were downregulated significantly at the induction site and upregulated at the effector site. The genes associated with SIgA production were downregulated significantly at the induction site. In contrast, the expression of the Toll-like receptor-related genes was upregulated significantly at the effector site. The frequencies of dendritic cells, B cells, and CD8 + T cells were upregulated at the 2 sites. The SIgA content decreased significantly in the ileal mucosa. @*Conclusions@#PCV2 infections can cause damage to the ileum that is associated with changes in immune-related gene expression, immune-related cell subsets, and SIgA production.These findings elucidated the molecular changes in the ileum after a PCV2 infection from the perspective of intestinal mucosal immunity, which provides insights into a further study for PCV2-induced enteritis.

ABSTRACT

Purpose@#The presentations and geographic incidence of pediatric non-Hodgkin lymphoma (NHL) differfrom those of adults. This study delineated the characteristics and outcomes of pediatricNHL in East Asia. @*Materials and Methods@#Medical records of 749 pediatric patients with NHL treated at participating institutions inmainland China, Japan, Korea, and Taiwan from January 2008 to December 2013 werereviewed. Demographic and clinical features, survival outcomes, and putative prognosticfactors were analyzed. @*Results@#Five hundred thirty patients (71%) were male. The most common pathologic subtypes wereBurkitt lymphoma (BL) (36%). Six hundred seven patients (81%) had advanced diseases atdiagnosis. The 5-year overall survival and event-free survival (EFS) rates were 89% and 84%.The 5-year EFS rates of BL, lymphoblastic lymphoma, and diffuse large B-cell lymphomawere 88%, 88%, and 89%, and those of anaplastic large cell lymphoma (ALCL) and peripheralT-cell lymphoma (PTCL) were 71% and 56% (p 250 IU/mL), and advanced disease at diagnosis( stage III) were associated with poor outcomes (p < 0.05). ALCL and PTCL relapsedmore frequently than other pathologic subtypes (p < 0.001). @*Conclusion@#In East Asia, PTCL was more frequent than in Western countries, and bone marrow involvementdid not affect treatment outcome. This international study should motivate future collaborativestudy on NHL in East Asia.

ABSTRACT

@#Objective    To determine the effectiveness of continuous intercostal nerve block for pain relief after thoracotomy. Methods    From November 2017 to October 2018, 120 patients who received thoracotomy procedure in our hospital were collected, including 60 males and 60 females aged 40-77 (58.10±7.00) years. The patients were randomly allocated into three groups by digital table including a continuous intercostal nerve block group (group A, n=40), a single intercostal nerve block group (group B, n=40), and an epidural analgesia group (group C, n=40). All the groups received the same basic analgesia. The pain scores and rescue analgesic doses were compared. Results    On postoperative day (POD) 0, all groups achieved effective pain control, and the visual analogue score was 2.02±0.39 points in the group A, 2.13±0.75 points in the group B and 2.03±0.69 points in the group C (P>0.05). On POD 0-2 and POD 3-4 (without basement analgesia), there was no significant difference between the group A and group C in the pain scores (2.08±0.28 points vs. 1.93±0.53 points, 3.20±0.53 points vs. 3.46±0.47 points, P>0.05), however, the difference between POD 0-2 and POD 3-4 in each group was stastically different (group A, 2.08±0.28 points vs. 3.20±0.53 points; group B, 2.42±0.73 points vs. 5.45±0.99 points; group C 1.93±0.53 points vs. 3.46±0.47 points, P<0.05). In terms of the rescue analgesic doses, there was no significant difference between the group A and group C (220.00±64.08 mg vs. 225.38±78.85 mg, P>0.05); it was larger in the group B than that in the group A and group C (343.33±119.56 mg vs. 220.00±64.08 mg; 343.33±119.56 mg vs. 225.38±78.85 mg, P<0.05). Conclusion    Multimodal analgesia is an optimal choice in the initial stage after thoracotomy surgery. Continuous intercostal nerve block is an effective way to pain management in patients with thoracotomy.

ABSTRACT

Objective:To analyze the effect of the multipoint tiny incision with continuous buried suture method in double eyelidplasty for patients with mild or moderate dermatolysis.Methods:Totally, 1 161 patients from May 2008 to February 2019 underwent the double-eyelid surgical procedure with the multipoint tiny incision with continuous buried suture method. 1 148 patients were female and 13 patients were male, ranging from 25 to 50 years old. All the patients had normal single-eyelid or inborn narrow double-eyelid without blepharoptosis and they were performed double eyelidplasty for the first time. During the operation, moderate orbicularis oculi muscle and orbital septum fat were cut down from the four or five tiny incisions which were all 2 mm long. Skin levator fixation was performed through continuous buring suture between subcutaneous and the levator aponeurosis. Postoperative follow-up time points were 3 months, 1 year and 5 years.Results:There were 10 patients that showed slight asymmetry, 8 patients' eyes showed shallow creases and 5 patients' double eyelids narrowed. These 23 patients were operated for the second time. Besides that, all the creases were symmetry, parallel and natural. Notched scars did not occur, and patients' satisfaction was achieved in the rest of the cases.Conclusions:Our double eyelid procedure creates natural and beautiful double eyelids without depressed scars. The blepharoplasty of multipoint tiny incision with continuous buried suture method can produce a desired aesthetic effect and it lasts for a long time.

ABSTRACT

Objective@#To explore the imaging manifestations of thoracic CT in patients with Gaucher disease (GD) in order to improve the diagnostic ability.@*Methods@#Forty-three patients with GD were collected from May 2003 to October 2018 in Beijing Children′s Hospital, including 25 males and 18 females, aged from 10 to 34 years, with an average age of (21±6) years. All the patients underwent routine chest CT examinations, and analysis and description of pulmonary interstitial and parenchyma imaging manifestations were performed.@*Results@#Among the 43 GD patients, 20 patients presented with abnormal chest CT findings: 10 showed diffuse interlobular septa thickening, mainly distributed in the lower lobes of both lungs; 5 showed ground glass opacities in a single or multiple lobes of the lung. There were 2 cases with small nodules, which showed round-like nodules of different sizes. One case had pulmonary fibrosis, especially in the left upper lobe. Other manifestations included bullae in 3 cases,localized pleural thickening in 2 cases, pneumothorax in 1 case; pulmonary hypertension in 1 case and thymus enlargement in 12 cases. Most of the GD patients had pulmonary lesions between 10 and 14 years old. The signs of interlobular septa thickening and thymus enlargement were common, with 5 cases in each age group.@*Conclusions@#GD involves the lungs in half of the patients. The manifestations of the lungs are diverse, and most of them are diffuse interstitial lesions. The main signs are interlobular septal thickening and ground glass opacity, which are consistent with the pathology of Gaucher cell infiltration.But the signs are not specific, the diagnosis should be made in combination with the clinical information, and attention should be paid to the differentiation of lung infiltration caused by other diseases.

ABSTRACT

Purposes: This study aimed to investigate the efficacy of ultrasound (US)-, computed tomography (CT)-, and magnetic resonance imaging (MRI)-guided radiofrequency ablation (RFA) for the treatment of hepatocellular carcinoma (HCC). Materials and Methods: This retrospective study included 141 patients with HCC who were treated with US-guided (n = 29), CT-guided (n = 50), or MRI-guided RFA (n = 62). The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS), technique success (TS), and technique efficacy (TE). Cox model and logistic regression were used to determine the risk factors for tumor recurrence and TE. Results: The US, CT, and MRI groups did not show a significant difference in terms of baseline variables. The three groups did not differ significantly in PFS rate (P = 0.072) and OS rate (P = 0.231). The PFS rates at 3 years for the US, CT, and MRI groups were 40.90%, not reached, and 14.80%, respectively. The OS rates at 3 years were 94.70%, 97.50%, and 85.50% for US, CT, and MRI groups, respectively. No significant differences were observed between the three groups in terms of TS rate (P = 0.113) and TE rate (P = 0.682). In multivariate analysis, liver cirrhosis (P = 0.001), level of alpha-fetoprotein (AFP, P = 0.004), and number of tumors (P = 0.012) were independent risk factors for PFS. For TE, the level of AFP (P = 0.018) was an independent factor. Conclusion: US-, CT-, and MRI-guided RFA was effective for treating HCC patients. Liver cirrhosis, AFP level, and tumor number were associated with tumor recurrence, and the level of AFP was an independent risk factor affecting TE

ABSTRACT

Objective@#To analyze the therapeutic effect of a modified LMB89 Group C regimen in the treatment of pediatric high-risk Burkitt lymphoma.@*Methods@#The clinical data of 172 children with newly diagnosed high-risk Burkitt lymphoma from January 2007 to April 2017 were retrospectively analyzed. All the cases were treated with the modified LMB89 Group C regimen.@*Results@#The median age of the patients was 6 (1-14) years. The sex ratio was 5.1∶1, 144 boys (83.7%) and 28 girls (16.3%) . According to St. Jude staging classification, 2 patients (1.2%) were in stage Ⅱ, 54 (31.4%) in stage Ⅲ and 116 (67.4%) in stage Ⅳ. Of them, 46 patients (26.7%) had mature B cell acute lymphoblastic leukemia (B-ALL) , and 52 patients had central nervous system (CNS) involvement. According to risk group, the patients can be divided into group C1 (CNS1, without testicles/ovaries involvement, n=65) , group C2 (CNS2, testicles/ovaries involvement, n=55) and group C3 (CNS3, n=52) . A total of 145 patients received rituximab combined with chemotherapy during the treatment, 10 patients suffered from progressive disease and died, and 5 patients relapsed. Treatment-related mortality was 2.9%. With a median follow-up of 36.0 (0.5-119.0) months, 3-year overall survival (OS) rate was (88.9±2.4) % and event free survival (EFS) rate was (87.9±2.6) % for all patients. 3-year EFS rates were (96.9±2.1) %, (90.9±3.9) % and (73.4±6.5) % for Group C1, C2 and C3 respectively, and that of Group C3 was significantly lower than that of Group C1 (χ2=12.939, P=0.001) and Group C2 (χ2=6.302, P=0.036) . The 3-year EFS rates were (79.3±6.8) % and (44.4±16.6) % for patients in group C3 treated with chemotherapy combined with rituximab and chemotherapy alone (χ2=5.972, P=0.015) . Multivariable Cox regression analysis showed that Stage Ⅳ (including B-ALL) , residual diseases in mid-term evaluation were independent unfavorable prognostic factors[HR=4.241 (95%CI 1.163-27.332) , P=0.026; HR=32.184 (95%CI 11.441-99.996) , P<0.001].@*Conclusions@#The modified LMB89 Group C regimen has ideal effect for the children with high-risk Burkitt lymphoma.

ABSTRACT

Objective@#To establish a quantitative assay of serum Golgi protein 73 (GP73) using xMAP technology and evaluate its performance.@*Methods@#Monoclonal antibodies against GP73 were prepared and purified, and antibody pair screening was performed by double-antibody sandwich enzyme-linked immunosorbent assay. The screened antibodies were used to construct a Luminex liquid chip detection system, and the analysis performance of the detection system was evaluated. The serum levels of GP73 were detected in 90 clinical samples from healthy controls and patients with chronic hepatitis B infection (CHB) and hepatocellular carcinoma (HCC).@*Results@#Five anti-GP73 monoclonal antibodies were prepared and purified, and 5 antibody pairs were successfully screened. The Luminex liquid chip detection system of GP73 was successfully constructed using 8F10D1 and 10B9F11 antibody pairs. The analytical performance evaluation showed that the sensitivity of this system was 0.25 ng/ml and the dynamic range was 0.25-100 ng/ml. No cross reactivity was observed. The intra- and inter-assay variation for GP73 was <8% and <11%, respectively. The recovery was 83%-92%. The linear regression equation was y=1.141x+ 6.436 (r2=0.998 4, P<0.001). The GP73 concentrations in the serum samples of healthy control, CHB group, and HCC group were 42.8 (38.68, 55.90) ng/ml, 61.49 (43.59, 81) ng/ml, and 122.78 (49.36 liter, 264.55) ng/ml, respectively. The levels of GP73 in HCC group were significantly higher than those in CHB group and healthy controls (P<0.05). Moreover, the levels of GP73 in CHB group were significantly higher than those in healthy controls (P<0.05).@*Conclusions@#A liquid chip detection system of GP73 was successfully constructed. It provides a powerful tool for the clinical application of GP73 in the future.

ABSTRACT

Objective@#To summarize the clinical data of diffuse large B-cell lymphoma (DLBCL) in children and to evaluate the efficacy of Beijing Children′s Hospital B cell lymphoma protocol in the treatment of pediatric DLBCL.@*Methods@#The data (clinical, pathology, lab and image data) of 46 pediatric DLBCL admitted to the treatment group of Beijing Children′s Hospital from January 2005 to June 2017 were collected and analyzed retrospectively. According to the risk factors of staging, existence of poor prognosis genes and giant tumors, stratified treatment was carried out according to the international standard modified LMB89 regimen with high dose and short course. The Kaplan-Meier method was used to calculate the event free survival (EFS) and the overall survival (OS).@*Results@#(1) Among the 46 cases, there were 33 males and 13 females. The median age was 8.0 years. The time from the initial symptom onset to the diagnosis was more than 15 days in 45 children. Fourteen cases had B group symptoms (fever, night sweat, and weight lost), 25 cases had extranodal disease, 39 cases were stage Ⅲ and Ⅳ, 12 cases had bone marrow involvement, 3 cases had jawbone involvement. Thirty cases were group B and 16 cases were group C in the treatment group. (2) Initial symptoms: 6 cases had cervical mass, 20 cases had abdominal mass, 10 had abdominal pain with acute abdomen, 8 cases had fever, 2 cases had snore or upper respiratory tract obstruction. (3) Pathology result: 40 cases were germinal center B cell DLBCL, 6 cases were non germinal center B cell DLBCL, no case had the MYC gene rupture, double hit lymphoma and triple hit lymphoma. (4) Complication and evaluation: the tumor lysis syndrome was seen in 3 cases initially, severe infection and delayed treatment was seen in 1 case, no treatment related death. The first evaluation showed all cases were sensitive to chemotherapy (shrink>25%), the second evaluation showed 1 case had residual disease, the others were complete remission. (5) Treatment and outcome: the 5 year-EFS was the same with 5 year-OS, both were (97.8±2.2) %. Two cases relapsed after treatment off, early relapse was seen in 1 case, and died because of abandoning treatment. Late relapse was seen in 1 case and got a complete remission after Rituximab+group C protocol treatment.@*Conclusions@#Pediatric DLBCL was common in school aged boys, most cases were at middle and late stage at the time of diagnosis. DLBCL had a good prognosis after the treatment with Beijing Children′s Hospital′s B cell lymphoma protocol, but late relapse could be seen.
