Objective To investigate the diagnostic value of serum ferritin in children with systemic onset juvenile idiopathic arthritis (SO-JIA). Methods Fifty-seven patients with fever of unknown origin (rectal temperature>38.5 ℃ ) over two weeks and hospitalized in our general medicine ward longer than one week were enrolled in this study. Patients were recorded the course of fever, elinieal symptoms and signs including rash and swollen joints/arthralgia, laboratory tests including complete blood cell count, C-reactive protein, erythroeyte sedimentation rate, lactate dehydrogenase and the level of serum ferritin. SPSS 10.0 was used for statistical analysis. Results Two of 57 patients could not be diagnosed before discharge. The other 55 patients whose diagnosis was confirmed were divided into four groups. Twenty-five patients were SO-JIA,12 patients had hematologic or oncological diseases, 12 patients had infectious diseases and 6 patients had other rheumatic diseases. The level of serum ferritin was significantly higher (P<0.01) in SO-JIA group than in other groups. Moreover, the levels of serum ferritin in SO-JIA group were all higher than normal and the levels of serum ferritin in 76% of SO-JIA group were more than five-fold elevation. Four cut-off levels of serum ferritin level for the diagnosis of SO-JIA were selected based on clinical practice and ROC curve. When the cut-off levels of serum ferritin were 328.25, 529.50, 731.05 ng/ml and 1121.10 ng/ml, the sensitivity for the diagnosis were 100%, 88%, 72%, and 64% respectively, the specificity were 77%, 87%, 90% and 100%,respectively. Conclusion Serum ferritin is valuable for the diagnosis of SO-JIA and 529.50 ng/ml may be a good cut-off level

OBJECTIVETo investigate the expression of osteopontin (OPN) splice variant mRNA, including the three isoforms OPN-A, OPN-B, and OPN-C, to explore its correlation with clinicopathologic features in gastric cancer, and to elucidate their role in tumor invasion and distant metastasis of gastric cancer.

METHODSThe expression of OPN-A, OPN-B and OPN-C mRNA were detected by real-time reverse transcriptase-polymerase chain reaction in 66 gastric cancer tissues. The relationship between the expression of OPN-A, OPN-B and OPN-C mRNA and clinicopathologic features of gastric cancer was analyzed.

RESULTSThe expression of OPN-C mRNA in the gastric cancer tissue was 3.21-fold higher than that in peritumoral mucosal tissue, showing a significant difference between them (P < 0.001). OPN-C mRNA expression was correlated with the depth of tumor invasion, tumor diameter, lymph node meatastasis, distant meatastasis and had no correlation with differentiation grades. The low expression of OPN-C mRNA was correlated with long survival benefit (P = 0.03). The expression of OPN-A and OPN-B mRNA had no significant relationship with clinicopathologic features of gastric cancer.

CONCLUSIONSOne of the isoform of osteopontin (OPN) OPN-C mRNA is overexpressed in gastric cancer. The overexpression of OPN-C mRNA may reflect the progression and is associated with the prognosis of gastric cancer. OPN-C mRNA may have value as a prognostic biomarker in gastric cancer. However, the expression of OPN-A and OPN-B are not correlated with the progression and metastasis of gastric cancer.

Objective To study the clinical characteristics of neonatal macrophage activation syndrome (MAS) associated with maternal rheumatic diseases and improve the understanding of neonatal MAS.Method Clinical data of MAS in a newborn infant with adult-onset Still's disease (AOSD) mother was retrospectively studied.From the establishment day of databases (CNKI,VIP,Wanfang,Pubmed and Embase) to December 2017,literature were retrieved with key words including "newborn","macrophage activation syndrome" and "hemophagocytic lymphohistiocytosis (HLH) ".Clinical features of infant MAS/HLH with maternal rheumatic diseases were summarized.Result A 27-day-old boy with AOSD mother manifested with fever,watery stools,irritability,prominent enlargement of right parotid gland and right cervical lymphadenitis.The infant was diagnosed with MAS due to coagulopathy,multiple organ dysfunction,hypofibrinogenemia and increased levels of ferritin.Anti-SSA/Ro52kD and stool rotavims antigen were positive.The infant recovered with intravenous immunoglobulin and steroids therapy.Follow-up at 2-year-old were normal.A total of 3 other cases of neonatal MAS/HLH were retrieved.All patients had high fever,hepatosplenomegaly and multiple organ dysfunction,impaired digestive system (abdominal distention,diarrhea and ascites),disseminated intravascular coagulation (2 cases),mental disorders (1 case),complete atrioventricular block (1 case) and severe hypotension (1 case).Laboratory results showed thrombocytopenia,elevated level of hepatic enzyme and serum ferritin in all patients.Targeted panel-based next generation sequencing were all negative for pathogenic gene mutations.After treatments of steroids,intravenous immunoglobulin and chemotherapy,all patients improved and ultimately cured.Conclusion In view of the impacts of the maternal rheumatic diseases on fetus,newborns with early onset high fever and hepatosplenomegaly should be suspected of MAS.Early diagnosis and effective treatment are crucial for clinical improvement.

Objective To analyse the risk factors associated with spontaneous intestinal perforation (SIP) in extremely premature infants/extremely low birth weight infants. Method From January 2015 to December 2018, infants with gestational age (GA)<28 weeks or birth weight (BW)<1000 g admitted to our neonatal intensive care unit were enrolled to the retrospective nested case-control study.The clinical data of SIP infants (SIP group) and infants with the same GA but without SIP (control group) were randomly selected and compared. Multivariable Logistic regression was used to analyse the risk factors of SIP. Result A total of 409 extremely premature infants/extremely low birth weight infants were born during the study period. Among them, 25 SIP infants and 55 controls were enrolled. The incidence of SIP in infants with GA 22～25 weeks was 11.8％(16/136), which is higher than infants with GA 26～27 weeks (2.0％, 5/247) (χ2=16.057, P<0.001). The incidence of SIP in infants with BW 400～749 g was 13.0％(14/108), which is higher than infants with BW 750～999 g (3.4％, 8/236) (χ2=11.343, P=0.001). Multivariate Logistic regression analysis showed that twins (OR=4.153, 95％CI 1.392～12.384, P=0.011), umbilical veins catheterization (OR=15.942, 95％CI 1.026～247.789, P=0.048) and ibuprofen use within 3 days after birth (OR=15.387, 95％CI 1.519～155.883, P=0.021) were independent risk factors of SIP. Conclusion The smaller the GA and BW, the higher the incidence of SIP. Twins,umbilical veins catheterization and ibuprofen use early after birth may be independent risk factors of SIP.

Background: Red blood cell distribution width/platelet count ratio (RPR) is a reliable prognostic assessment indicator for numerous diseases. However, no studies to date have examined the relationship between RPR and the prognosis of diffuse large B-cell lymphoma (DLBCL).Therefore, this study aimed to investigate the correlation between RPR and the clinical characteristics and prognosis of patients with diffuse large B-cell lymphoma. Methods: We retrospectively studied 143 patients with newly diagnosed DLBCL and used the median value as the RPR threshold. We also investigated the correlation of pretreatment RPR level with clinical characteristics and its impact on DLBCL prognosis. Results: Using the median value as the cut-off, patients with DLBCL were divided into a low RPR group (＜0.0549) and a high RPR group (≥0.0549). Patients in the high RPR group were older, had a later Ann Arbor stage, were prone to bone marrow invasion, and had a higher National Comprehensive Cancer Network International Prognostic Index score (P ＜ 0.05). A survival analysis showed that progression-free survival (PFS) (P =0.003) and overall survival (OS) (P ＜0.0001) were significantly shorter in the high versus low RPR group. A multifactorial Cox analysis showed that bone marrow invasion and elevated lactate dehydrogenase (LDH) were separate risk factors for PFS (P ＜0.05), while an RPR ≥0.0549 and elevated LDH were separate risk factors for OS (P ＜0.05). Conclusion A high RPR (≥0.0549) in patients with newly diagnosed DLBCL is an independent risk factor for a poor prognosis.

BACKGROUND: Immunoneoadjuvant therapy opens a new prospect for local advanced lung cancer. The aim of our study was to explore the safety and feasibility of robotic-assisted bronchial sleeve resection in patients with locally advanced non-small cell lung cancer (NSCLC) after neoadjuvant chemoimmunotherapy. METHODS: Data of 13 patients with locally advanced NSCLC that underwent bronchial sleeve resection after neoadjuvant chemoimmunotherapy during August 2020 and February 2021 were retrospectively included. According to the surgical methods, patients were divided into thoracotomy bronchial sleeve resection (TBSR) group and robot-assisted bronchial sleeve resection (RABSR) group. Oncology, intraoperative, and postoperative data in the two groups were compared. RESULTS: The two groups of patients operated smoothly, the postoperative pathology confirmed that all the tumor lesions achieved R0 resection, and RABSR group no patient was transferred to thoracotomy during surgery. Partial remission (PR) rate and major pathological remissions (MPR) rate of patients in the TBSR group were 71.43% and 42.86%, respectively. Complete pathological response (pCR) was 28.57%. They were 66.67%, 50.00% and 33.33% in RABSR group, respectively. There were no significant differences in operative duration, number of lymph nodes dissected, intraoperative blood loss, postoperative drainage time and postoperative hospital stay between the two groups, but the bronchial anastomosis time of RABSR group was relatively short. Both groups of patients had a good prognosis. Successfully discharged from the hospital and post-operative 90-d mortality rate was 0. CONCLUSIONS In patients with locally advanced central NSCLC after neoadjuvant chemoimmunotherapy can achieve the tumor reduction, tumor stage decline and increase the R0 resection rate, bronchial sleeve resection is safe and feasible. Under the premise of following the two principles of surgical safety and realizing the tumor R0 resection, robot-assisted bronchial sleeve resection can be preferred.
