The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.

OBJECTIVE: To investigate the expression and clinical significance of soluble interleukin-2 receptor(sIL-2R) in patients with multiple myeloma(MM). METHODS: 54 newly diagnosed MM patients in the Second Affiliated Hospital of Fujian Medical University from February 2020 to December 2021 were selected as the observation group, and 60 healthy people in our hospital in the same period were selected as the control group. The expression levels of sIL-2R in the serum of the two groups were detected by enzyme-linked immunosorbent assay. The differences of sIL-2R expression level among different clinical parameter groups in MM patients were compared. The clinical parameters include:gender, age, ISS stage, hemoglobin, albumin, serum creatinine, lactate dehydrogenase and β₂-microglobulin, blood calcium, bone marrow plasma cell ratio and treatment response. The relationship between sIL-2R expression level and progression-free survival(PFS) and overall survival(OS) in MM patients were analyzed. RESULTS: The expression of serum SIL-2R in MM patients was significantly higher than that in healthy control group (P<0.05). The expression of sIL-2R in MM patients who did not achieve complete remission(CR) was significantly higher than those of CR patients (P=0.037). There was no significant difference in the expression of serum sIL-2R between the groups of different sex, age, ISS stage, hemoglobin concentration, albumin content, serum creatinine level, lactate dehydrogenase level, the content of β₂-microglobulin, the concentration of blood calcium, and the proportion of bone marrow plasma cells(P>0.05). The PFS of sIL-2R high expression group(15 months) was shorter than that of sIL-2R low expression group (22 months), which was significant difference (P=0.041). But there was no significant difference in OS between sIL-2R high expression group and sIL-2R low expression group (P=0.124). Univariate analysis results showed that the high expression of serum sIL-2R was associated with poor PFS in MM patients. Multivariate analysis results showed that the high expression of serum sIL-2R was still an independent adverse prognostic factor for PFS in MM patients, However, the expression of serum sIL-2R was not statistically significant in evaluating OS in MM patients by univariate and multivariate analysis. CONCLUSION The expression of serum sIL-2R in MM patients was significantly higher than that in healthy people. Serum sIL-2R is an independent prognostic factor of PFS in MM patients.

AIM:To identify the reasons for not improving visual acuity of patients with diabetic macular edema(DME)and its correlation with optical coherent tomography(OCT)imaging characteristics. They were treated with anti-vascular endothelial growth factor(VEGF)again after an interruption of treatment due to the COVID-19 pandemic.METHODS: Retrospective cases study. A total of 31 patients(40 eyes)with DME and treated with anti-VEGF drugs in the Department of Ophthalmology of the First Affiliated Hospital of Xi'an Jiaotong University between December 2019 and July 2020 were selected. All patients had an treatment history of interruption due to COVID-19. Based on the behavioral standard of best corrected visual acuity(BCVA)at 1mo after re-treatment, they were divided into improved visual acuity group(14 eyes)and non-improved visual acuity group(26 eyes). All patients received comprehensive ophthalmic examinations, including BCVA, intraocular pressure, OCT, fundus photography, and fundus fluorescein angiography(FFA). The central retinal thickness(CRT), hyper-reflective retinal dots(HRD), subretinal fluid(SRF), intraretinal fluid(IRF), disorganization of the inner retinal layers(DRIL)and ellipsoid zone disruption(EZD)were quantified by Image J. The correlation between BCVA and CRT, the number of HRD, the diameter of SRF and IRF, and the height of DRIL and EDZ width at 1mo after treatment were analyzed by Spearman correlation.RESULTS: The proportion of HRD in OCT was significantly higher in the non-improved visual acuity group than that in the improved visual acuity group(χ2=5.43, P=0.0072); There was a positive correlation between the difference of BCVA(LogMAR)and CRT change in DME patients after treatment(rs=0.406, P=0.009); There was a positive correlation between BCVA(LogMAR)and EZD width after treatment(rs=0.358, P=0.023). There was no correlation between BCVA(LogMAR)after treatment and the number of CRT(rs=-0.086,P=0.600)and HRD(rs=-0.115,P=0.482), the diameter and height of SRF(rs=0.102,P=0.530; rs=0.100,P=0.538)and IRF(rs=0.134,P=0.410; rs=-0.014,P=0.932), and the width of DRIL(rs=0.089,P=0.587).CONCLUSION:The probability of retinal HRD was significantly higher in patients with no visual improvement than that in patients with visual improvement after the re-treatment with anti-VEGF due to the treatment interruption during COVID-19. EZD width was also closely correlated to the prognosis of visual acuity. As for these patients, HRD manifestations in OCT should be comprehensively considered, taking intravitreal injection of glucocorticoid as an auxiliary strategy if necessary.

Objective:To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients.Methods:The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed.Results:The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively ( P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively ( P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm 3, the median survival time of SIB and No-SIB group was 34.7 and 30.3 months ( P=0.155), respectively. In the patients whose GTV volume>50 cm 3, the median survival time of SIB and No-SIB group was 16.1 and 20.1 months ( P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group ( P<0.001). Conclusions:The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.

OBJECTIVE: To analyze the prevalence and risk factors of hyperuricemia in male workers in a petrochemical enterprise. METHODS: A total of 1 604 male workers in a petrochemical production enterprise was selected as the study subjects using judgment sampling method. The living habits and health status of the workers were investigated, and the related examination results of hyperuricemia were collected through the “Occupational Health Surveillance and Monitoring Information System” independently developed by Guangdong Province Hospital for Occupational Disease Prevention and Treatment, and the influencing factors were analyzed. RESULTS: The prevalence of hyperuricemia in male workers was 29.6%(474/1 604). Multivariate Logistic regression analysis showed that high diastolic blood pressure, high triglyceride(TG), overweight and obesity were risk factors for hyperuricemia in male workers after excluding age, smoking and other confounding factors(all P<0.01). The results of restricted cubic spline model showed that there was a linear dose-response relationship between hyperuricemia and body mass index and diastolic blood pressure( χ~2=36.19 and 21.46, all P<0.01), and a non-linear dose-response relationship between hyperuricemia and TG( χ~2=14.56, P<0.01). CONCLUSION: The risk factors for hyperuricemia among male workers in the petrochemical enterprise included elevated diastolic blood pressure, elevated TG, overweight and obesity, and there was a dose-response relationship.

OBJECTIVE: To study the potential significance and clinical application of FGFR1 gene abnormality in the diagnosis, clinical features, pathological mechanism and treatment in hematological tumors. METHODS: Clinical data of total of 29 patient with chromosome of 8 short arm (8P) abnormality who had more comprehensive medical history from 2013 to 2018 were collected. The karyotype analysis of bone marrow chromosomes in patients was carried out by using chromosome R band banding technique. FGFR1 gene was detected by using fluorescence in situ hybridization (FISH). RESULTS: Seven cases of FGFR1 gene abnormalities were decteted, including 3 cases of FGFR1 gene amplification, 2 cases of translocation, and 2 cases of deletion. Five patients with FGFR1 gene amplification or deletion not accompaned with eosinophilia, moreover the chromosome was a complex karyotype with poor prognosis; Two cases of FGFR1 gene translocation were non-complex chromosomal translocation and one of which survived for 6 years after bone marrow transplantation, the other chromosome karyotype showed no rearrangement of 8 short arm. However, FGFR1 gene rearrangement was confirmed by FISH analysis, which was a rare insertional translocation. CONCLUSION FGFR1 gene amplification or deletion often occur in cases with complex karyotype, which not accompany eosinophilia, moreover have poor prognosis. The patients with FGFR1 gene translocation accompany eosinophilia which is consistent with the clinical characteristics of myeloid / lymphoid neoplasms with FGFR1 abnormality. Karyotype analysis combined with FISH method can improve the detection of abnormal clones.

In this study, we aimed to evaluate the toxic effects, changes in life span, and expression of various metabolism-related genes in Caenorhabditis elegans, using RNA interference (RNAi) and mutant strains, after 3-bromopyruvate (3-BrPA) treatment. C. elegans was treated with various concentrations of 3-BrPA on nematode growth medium (NGM) plates, and their survival was monitored every 24 h. The expression of genes related to metabolism was measured by the real-time fluorescent quantitative polymerase chain reaction (qPCR). Nematode survival in the presence of 3-BrPA was also studied after silencing three hexokinase (HK) genes. The average life span of C. elegans cultured on NGM with 3-BrPA was shortened to 5.7 d compared with 7.7 d in the control group. hxk-1, hxk-2, and hxk-3 were overexpressed after the treatment with 3-BrPA. After successfully interfering hxk-1, hxk-2, and hxk-3, the 50% lethal concentration (LC₅₀) of all mutant nematodes decreased with 3-BrPA treatment for 24 h compared with that of the control. All the cyp35 genes tested were overexpressed, except cyp-35B3. The induction of cyp-35A1 expression was most obvious. The LC₅₀ values of the mutant strains cyp-35A1, cyp-35A2, cyp-35A4, cyp-35B3, and cyp-35C1 were lower than that of the control. Thus, the toxicity of 3-BrPA is closely related to its effect on hexokinase metabolism in nematodes, and the cyp-35 family plays a key role in the metabolism of 3-BrPA.

Objective:To evaluate the survival and prognostic factors of radiotherapy in patient with Ⅳ stage esophageal squamous carcinoma treated with radiation or chemoradiation.Methods:The medical records of 608 patients with stage Ⅳ esophageal squamous cell carcinoma who met the inclusion criteria in 10 medical centers in China from 2002 to 2016 were retrospectively analyzed. The overall survival and prognostic factors of all patients at 1, 3 and 5 years were analyzed.Results:The 1-, 3-, 5- year overall survival (OS) rates was 66.7%, 29.5% and 24.3% in stage ⅣA patients, and 58.8%, 29.0% and 23.5% in stage ⅣB patients. There was no statistical difference between the two groups ( P=0.255). Univariate analysis demonstrated that the length of lesion, treatment plan, planned tumor target volume (PGTV) dose, subsequent chemotherapy, and degrees of anemia, radiation esophagitis, radiation pneumonia were related to the prognoses of patients with Ⅳ stage esophageal carcinomas after radiotherapy and chemotherapy ( P<0.05). Multivariate analysis demonstrated that PGTV dose ( OR=0.693, P=0.004), radiation esophagitis ( OR=0.867, P=0.038), and radiation pneumonia ( OR=1.181, P=0.004) were independent prognostic factors for OS. Conclusions:For patients with stage Ⅳ esophageal squamous cell carcinoma, chemoradiotherapy followed by sequential chemotherapy is recommended, which can extend the total survival and improve the prognosis of the patients. PGTV dose more than 60 Gy has better efficacy.
