ABSTRACT
Objective: To establish and validate reference intervals of serum vitamin K for healthy children in China. Methods: A cross-sectional study was conducted from January 2020 to May 2023, involving 807 healthy children aged 0 to 14 years, selected by stratified random sampling based on the population distribution of children in eastern, central, western, and northeastern China. Sample collection was carried out in 16 hospitals across 12 provinces, autonomous regions, and municipalities. Basic information of the children was collected using a standardized self-design questionnaire. Serum levels of vitamin K1 and vitamin K2 (menaquinone-4 (MK-4), menaquinone-7 (MK-7)) were measured using liquid chromatography-tandem mass spectrometry. The reference intervals was established by direct approach. The children were divided into different groups by age. Inter-group comparisons were conducted using the Kruskal-Wallis non-parametric test, and the reference intervals (P2.5-P97.5) were determined using non-parametric methods. Screening 40 healthy children for small sample validation based on age groups within the reference range(25 from eastern, 10 from central, and 5 from western regions). Results: The age of the 807 children was 5.00 (2.00, 9.81) years, and 495 (61.3%) were males and 312 (38.7%) females. Reference intervals were established for 795 children, of whom 303 children were aged 1 month to 3 years and 492 were aged 4 to 14 years. The reference intervals for serum vitamin K1 were 0.09-4.54 µg/L for children aged 1 month to 3 years, and 0.10-1.73 µg/L for 4-14 years. For MK-7, the intervals were 0.07-1.42 µg/L for 1 month to 3 years and 0.19-2.03 µg/L for 4-14 years. The reference intervals for MK-4 in children aged 1 month to 14 years were 0-0.42 µg/L. The measured values of serum vitamin K1, MK-4, and MK-7 in the validation samples did not exceed the reference limit in more than 2 samples. Conclusion: Reference intervals for vitamin K1, MK-4, and MK-7 in healthy children aged 1 month to 14 years have been established and validated, and can be used to assess vitamin K nutritional status in children.

Objective: To assess the efficacy, safety, and related prognostic factors associated with the P-GemDOx regimen as a first-line treatment for patients with early-stage extranodal natural killer (NK) /T cell lymphoma (ENKTL) . Methods: A retrospective analysis was performed on sixty early-stage ENKTL patients treated with the P-GemDOx regimen who were admitted to the First Affiliated Hospital of Nanjing Medical University between August 2015 and May 2021. The Chi-square test or Fisher's exact test was used to compare group differences, and the Log-rank test was used to compare the differences in survival. Survival outcomes and prognostic factors were examined. Results: After completing 4 to 6 cycles of P-GemDOx chemotherapy, the overall response rate (ORR) was 88.3%, with forty-six patients (76.7% ) achieving complete response (CR). The 4-year progression-free survival (PFS) and overall survival (OS) rates were (66.3±7.1) % and (79.5±6.0) %, respectively. According to the PINK/PINK-E model, there was no significant difference in survival outcomes among risk groups. 23.3% of patients experienced progression of disease within 24 months (POD<24). OS estimates differed significantly (P<0.001) between the POD<24 group (n=14) and the POD≥24 group (n=46). Analysis showed that SUVmax > 12.8 at diagnosis, non-single nasal cavity infiltration, and response less than CR after 4-6 cycles all had a significant association with POD24. We used these data as the basis for predicting POD<24 international prognostic index (POD24-IPI). Patients were stratified into low-risk (no risk factors), intermediate-risk (one risk factor), or high risk (two or three risk factors). These groups were associated with 4-year OS rate of 100%, (85.6±9.7) %, and (65.0±10.2) %, respectively (P=0.014). The P-GemDOx regimen was well tolerated, with hematological toxicity being the main side effect. Conclusion: This study demonstrated that the P-GemDOx regimen is effective and safe in the first-line treatment of early-stage ENKTL, and POD24-IPI is a promising prognostic model.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum ß-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ2=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective: To analyze the genomic mutation of Mycobacterium tuberculosis (M. tuberculosis) isolated in endogenous activation period and estimate the molecular clock based on the whole genome sequencing data. Methods: Literatures of the whole genome research of endogenous reactivated tuberculosis were retrieved, and the corresponding whole genome sequencing data were downloaded. We extracted the single nucleotide polymorphisms (SNPs) and strain isolation time of initial treatment and relapse of tuberculosis cases, explored the relationship between the different SNPs and interval between initial treatment and relapse by Poisson regression model, calculated the M. tuberculosis molecular clock, and estimated the mutation rate. Results: When the generation time of M. tuberculosis was 18 hours, the mutation rate in 0-2 years, i.e. short-term endogenous activation, was 6.47×10-10 (95%CI: 5.59×10-10-7.44×10-10), which was significantly higher than that in 2-14 years in long term endogenous activation (3.27×10-10, 95%CI: 2.88×10-10-3.69×10-10). The mutation rates of 0-, 1-, 2-, 3-, 5- and 7-14 years were 7.10×10-10, 6.06×10-10, 4.24×10-10, 5.34×10-10, 2.59×10-10 and 1.26×10-10 respectively. Conclusions: In the period of endogenous reactivation, the mutation rate of M. tuberculosis decreases with the interval time between initial treatment and relapse, which verifies the clinically observed phenomenon that the relapse often occurs within two years after the initial treatment of tuberculosis.

Objective: To examine the clinical efficacy of 3 anti-reflux methods of digestive tract reconstruction after proximal gastrectomy for gastric cancer. Methods: The clinical data and follow-up data of gastric cancer patients who underwent anti-reflux reconstruction after proximal gastrectomy in 11 medical centers of China from September 2016 to August 2021 were retrospectively collected, including 273 males and 65 females, aging of (63±10) years (range: 28 to 91 years). Among them, 159 cases were performed with gastric tube anastomosis (GTA), 107 cases with double tract reconstruction (DTR), and 72 cases with double-flap technique (DFT), respectively. The duration of operation, length of postoperative hospital stay and early postoperative complications (referring to Clavien-Dindo classification) of different anti-reflux reconstruction methods were assessed. Body mass index, hemoglobin and albumin were used to reflect postoperative nutritional status. Reflux esophagitis was graded according to Los Angeles criteria based on the routinely gastroscopy within 12 months after surgery. The postoperative quality of life (QoL) was evaluated by Visick score system. The ANOVA analysis, Kruskal-Wallis rank sum test, χ2 test and Fisher's exact test were used for comparison between multiple groups, and further comparison among groups were performed with LSD, Tamhane's test or Bonferroni corrected χ2 test. The mixed effect model was used to compare the trends of Body mass index, hemoglobin and albumin over time among different groups. Results: The operation time of DFT was significantly longer than that of GTA and DTR ((352±63) minutes vs. (221±66) minutes, (352±63) minutes vs. (234±61) minutes, both P<0.01). The incidence of early complications with Clavien-Dindo grade â ¡ to â ¤ in GTA, DFT and DTR groups was 17.0% (27/159), 9.7% (7/72) and 10.3% (11/107), respectively, without significant difference among these three groups (χ2=3.51, P=0.173). Body mass index decreased more significantly in GTA than DFT group at 6 and 12 months after surgery (mean difference=1.721 kg/m2, P<0.01; mean difference=2.429 kg/m2, P<0.01). body mass index decreased significantly in DTR compared with DFT at 12 months after surgery (mean difference=1.319 kg/m2, P=0.027). There was no significant difference in hemoglobin or albumin fluctuation between different reconstruction methods perioperative. The incidence of reflux esophagitis one year after surgery in DTR group was 12.9% (4/31), which was lower than that in DFT (45.9% (17/37), χ2=8.63, P=0.003). Follow-up of postoperative quality of life showed the incidence of Visick grade 2 to 4 in DFT group was lower than that in GTA group (10.4% (7/67) vs. 34.6% (27/78), χ2=11.70, P=0.018), while there was no significant difference between DFT and DTR group (10.4% (7/67) vs. 22.2% (8/36, P>0.05). Conclusions: Compared with GTA and DTR, DFT is more time-consuming, but there is no significant difference in early complications among three methods. DFT reconstruction is more conducive to maintain postoperative nutritional status and improve QoL, especially compared with GTA. The risk of reflux esophagitis after DTR reconstruction is lower than that of DFT.

OBJECTIVE: To analyze the endemic status of schistosomiasis in Suzhou City from 2010 to 2020, so as to provide the evidence for formulating the future schistosomiasis control strategy. METHODS: The data pertaining to the endemic status of schistosomiasis in Suzhou City from 2010 to 2020 were retrieved from the annual schistosomiasis control report, the information management platform of schistosomiasis (parasitic diseases) in Jiangsu Province and the Parasitic Diseases Control Information Management System of Chinese Center for Disease Control and Prevention, including snail survey data, snail control data and schistosomiasis examination data, and were retrospectively reviewed. Differences of proportions were tested for statistical significance with chi-square test, and the trends in proportions were evaluated using the chi-square test for trends. RESULTS: Elimination of schistosomiasis was achieved in Suzhou City in 2018, and there were 3.528 9 million residents living in schistosomiasis-endemic villages of 81 townships in 9 counties. A total of 707 600 labor-days were used for snail survey in 11 586 village-times in Suzhou City from 2010 to 2020, covering 18 572.73 hm2, and snail habitats were detected with an area of 68.61 hm2, including emerging snail habitats of 37.30 hm2. A total of 23 144 snails were dissected, and no Schistosoma japonicum infection was detected. Reemerging and emerging snail habitats were predominantly found in inlands. During the period from 2010 to 2020, snail control was performed in Suzhou City for 71 000 labor-times, and snail control was done covering 269.34 hm2 through chemical treatment and covering 3.48 hm2 through environmental improvements. A total of 674 002 person-times received serological tests for S. japonicum infections in Suzhou City from 2010 to 2020, with seroprevalence of 0.38%, and a total of 33 835 person-times received stool examinations, with no egg-positives identified. The sero-prevalence of S. japonicum infections appeared an overall tendency towards a rise in Suzhou City from 2010 to 2020 (χ2 = 129.48, P < 0.001). The sero-prevalence of S. japonicum infections appeared high among local residents in 2016, and remained stable in other years, while the sero-prevalence of S. japonicum infections appeared an overall tendency towards a rise among mobile populations (χ2 = 54.11, P < 0.001). There were 278 800 and 175 202 serological tests among local residents and mobile populations in Suzhou City from 2013 to 2020, and 0.50% and 0.35% sero-prevalence rates were detected, respectively. The sero-prevalence of S. japonicum infections was significantly higher among local residents than among mobile populations in Suzhou City (χ2= 54.76, P < 0.001). CONCLUSIONS: There is a risk of rebound of schistosomiasis in Suzhou City. Integrated control should be reinforced to prevent the risk of rebound of schistosomiasis in Suzhou City.

Objective: To develop a predictive model for pathologic complete response (pCR) of ipsilateral supraclavicular lymph nodes (ISLN) after neoadjuvant chemotherapy for breast cancer and guide the local treatment. Methods: Two hundred and eleven consecutive breast cancer patients with first diagnosis of ipsilateral supraclavicular lymph node metastasis who underwent ipsilateral supraclavicular lymph node dissection and treated in the Breast Department of Henan Cancer Hospital from September 2012 to May 2019 were included. One hundred and forty two cases were divided into the training set while other 69 cases into the validation set. The factors affecting ipsilateral supraclavicular lymph node pCR (ispCR)of breast cancer after neoadjuvant chemotherapy were analyzed by univariate and multivariate logistic regression analyses, and a nomogram prediction model of ispCR was established. Internal and external validation evaluation of the nomogram prediction model were conducted by receiver operating characteristic (ROC) curve analysis and plotting calibration curves. Results: Univariate logistic regression analysis showed that Ki-67 index, number of axillary lymph node metastases, breast pCR, axillary pCR, and ISLN size after neoadjuvant chemotherapy were associated with ispCR of breast cancerafter neoadjuvant chemotherapy (P<0.05). Multivariate logistic regression analysis showed that the number of axillary lymph node metastases (OR=5.035, 95%CI: 1.722-14.721, P=0.003), breast pCR (OR=4.662, 95%CI: 1.456-14.922, P=0.010) and ISLN size after neoadjuvant chemotherapy (OR=4.231, 95%CI: 1.194-14.985, P=0.025) were independent predictors of ispCR of breast cancer after neoadjuvant chemotherapy. A nomogram prediction model of ispCR of breast cancer after neoadjuvant chemotherapy was constructed using five factors: number of axillary lymph node metastases, Ki-67 index, breast pCR, axillary pCR and size of ISLN after neoadjuvant chemotherapy. The areas under the ROC curve for the nomogram prediction model in the training and validation sets were 0.855 and 0.838, respectively, and the difference was not statistically significant (P=0.755). The 3-year disease-free survival rates of patients in the ispCR and non-ispCR groups after neoadjuvant chemotherapy were 64.3% and 54.8%, respectively, with statistically significant differences (P=0.024), the 3-year overall survival rates were 83.8% and 70.2%, respectively, without statistically significant difference (P=0.087). Conclusions: Disease free survival is significantly improved in breast cancer patients with ispCR after neoadjuvant chemotherapy. The constructed nomogram prediction model of ispCR of breast cancer patients after neoadjuvant chemotherapy is well fitted. Application of this prediction model can assist the development of local management strategies for the ipsilateral supraclavicular region after neoadjuvant chemotherapy and predict the long-term prognosis of breast cancer patients.

OBJECTIVE: This study was aimed to investigate the expression characteristics of STYXL1 in hepatocellular carcinoma (HCC), and to further analyze its regulatory role in promoting HCC development by targeting CELF2 to activate the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway. PATIENTS AND METHODS: Expression levels of STYXL1 in 25 pairs of HCC tissue specimens and paracancerous normal ones collected from HCC patients were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Meanwhile, qRT-PCR was also performed to further verify the expression of STYXL1 in HCC cell lines. In addition, after STYXL1 knockdown model was constructed by lentivirus transfection in HCC cell lines Hep3B and Huh7, the Cell Counting Kit-8 (CCK-8), cell colony formation, 5-Ethynyl-2'-deoxyuridine (EdU), and flow cytometry assays were performed to analyze the influence of STYXL1 on HCC cell functions. Furthermore, an in-depth study of the relationship between STYXL1 and CELF2 was conducted to figure out the underlying mechanism. RESULTS: The results of qRT-PCR revealed that the expression level of STYXL1 in HCC samples was remarkably higher than that in adjacent ones, and the difference was statistically significant. Compared with HCC patients with low expression of STYXL1, patients with high expression of STYXL1 had a higher overall survival rate. Similarly, the proliferation ability of HCC cells in sh-STYXL1 group remarkably decreased compared with controls, while the apoptosis ability was oppositely enhanced. In addition, Western Blotting results indicated that STYXL1 could elevate the expressions of PI3K/Akt pathway-related proteins. Meanwhile, a negative correlation between CELF2 and STYXL1 was identified in HCC tissues. Finally, the result of cell reverse experiments demonstrated that STYXL1 could affect the malignant progression of HCC via modulating CELF2 expression. CONCLUSIONS: STYXL1 expression was remarkably upregulated in HCC tissues, as well as in cell lines. Its level was closely related to the poor prognosis of HCC patients. In addition, STYXL1 might be able to accelerate HCC proliferation rate and inhibit cell apoptosis via downregulating CELF2 through the PI3K/Akt pathway.

Objective: To investigate general condition of children's rheumatic disease associated medical resources in Fujian Province. Methods: This questionnaire-based survey was conducted in 19 hospitals in Fujian province from December 2, 2018 to May 1, 2019. The questionnaire was designed to survey the general condition of the medical resources and the hospitalization of patients with rheumatic diseases from January 1, 2014 to December 1, 2018. Results: In the 19 hospitals, there were 15 general hospitals and 4 children's hospitals, and only 5 hospitals had children's rheumatic specialist clinic. There were only 53-62 beds for rheumatic disease patients in the 19 hospitals, accounting for 1.7%-2.0% of the total inpatient beds (3 137). There are 29 pediatric rheumatologists in total, accounting for 2.6% (29/1 120) of the total pediatricians. In the past five years, 613 patients with rheumatic diseases, accounting for 0.1% (613/625 214) of total hospitalized patients, were treated in these hospitals. Among them, 201 had juvenile idiopathic arthritis, 295 had systemic lupus erythematosus, 39 had dermatomyositis, 7 had scleroderma, and 57 had inflammatory bowel disease, 9 had Sjogren's syndrome, 5 had Behcet's disease, and none had overlap syndrome or mixed connective tissue disease. Conclusion: The medical resources of children rheumatic diseases in Fujian province are insufficient which need to be developed.

OBJECTIVE: Recently, the vital role of circular RNAs is discovered in many diseases, including tumor progression. Hepatocellular carcinoma (HCC) is one of the most ordinary malignant tumors. The purpose of our study is to detect the potential function of circ_0000885 in HCC to offer new biomarkers and targets. PATIENTS AND METHODS: The expression level of circ_0000885 in HCC tissues and cell lines was monitored by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). Pearson's Chi-square test was used to determine the association of circ_0000885 expression with several clinicopathological factors. Then knockdown of circ_0000885 was constructed to uncover its function in HCC. The cell growth ability was measured through the cell counting kit-8 (CCK-8) assay, colony formation assay, and cell cycle assay. The Western blot assay was performed to analyze the protein level of Caprin1. RESULTS: Circ_0000885 was highly expressed in HCC tissues than that in adjacent samples. The miR-532-5p expression was associated with lymphatic metastasis and TNM stage. The expression of circ_0000885 was also higher in HCC cell lines. The cell growth ability of HCC cells was inhibited after circ_0000885 was silenced. Furthermore, Caprin1 was inhibited via knockdown of circ_0000885. CONCLUSIONS: Circ_0000885 could enhance cell proliferation and regulate cell cycle of HCC by promoting Caprin1.

Objective: To evaluate the prognostic value of lymphocyte to monocyte ratio (LMR) and PET scan performed after first two cycles of chemotherapy (PET-2) in Hodgkin's lymphoma (HL) . Methods: The clinical data of 133 patients with HL diagnosed from January 2007 to March 2016 at the First Affiliated Hospital of Nanjing Medical University, were retrospectively analyzed. The X-tile software was used to calculate the optimal cut-off value of LMR. Kaplan-Meier method and Cox regression were used for survival analysis. Results: The median age of 133 HL patients was 33 (18-84) years, and the male to female ratio was 1.9â¶1. The optimal cut-off value of LMR was 2.5, and progression free survival (PFS) (P<0.001) and overall survival (OS) (P<0.001) were significantly lower in the LMR<2.5 group than that of LMR≥2.5. Multivariate survival analysis showed that LMR<2.5 was an independent predictor of PFS (P=0.002, HR=2.35, 95%CI 1.36-4.07) and OS (P=0.002, HR=10.36, 95%CI 2.35-45.66) in HL patients. The analysis of PET-2 from 56 HL patients showed that PET-2 positive patients had significantly poorer PFS (P=0.022) . After grouping LMR combined with PET-2, significant differences were found in PFS and OS between the three groups (P values were 0.009 and 0.012) . Conclusion: LMR<2.5 is an independent prognostic factor for patients with HL. PET-2 combined with LMR may have better prognostic value.

Objective: To analyze the survival and first-line immune-chemotherapy (CIT) of chronic lymphocytic leukemia (CLL) with abnormal TP53 gene in the era of traditional CIT. Methods: The clinical data of 118 CLL patients diagnosed from January 2003 to August 2017 were collected. Survival was analyzed according to indicators including sex, age, Binet risk stratification, B symptoms, ß(2)-microglobulin (ß(2)-MG) , immunoglobulin heavy chain variable region gene (IGHV) mutation status, chromosome karyotype and TP53 gene deletion/mutation. The efficacy of first-line CIT of 101 CLL patients was further analyzed. Results: Among 118 patients, median progression-free survival (PFS) was 12 (95%CI 10.148-13.852) months and median overall survival (OS) was 53 (95%CI 41.822-64.178) months, only 30.5% patients survived over 5 years. Low ß(2)-MG<3.5 mg/L indicated longer PFS (P=0.027) , female and Binet A patients had longer OS (P=0.011 and 0.013, respectively) . Of 118 patients, 17 (14.4%) didn't receive any therapy until follow-up time or the dead time. Among the 101 patients who received ≥1 CIT, median time to first treatment (TTFT) was 1 (0-62) months, patients in Binet A had longer TTFT (P<0.001) compared to the patients in Binet B/C. According to statistical needs, we divided those first-line CIT into four groups: there were 30 cases (29.7%) in mild chemotherapy group (mainly treated with nitrogen mustard phenylbutyrate or rituximab alone) , 32 cases (31.7%) in the fludarabine-containing group, 23 cases (22.8%) in high-dose methyprednisolone (HDMP) containing group and 16 cases (15.8%) in the other chemotherapy group. The first regimen contained HDMP can bring longer PFS (P<0.001) , however the OS between four groups had no statistical differences. Conclusion: CLL patients with abnormal TP53 gene had poor response to immunotherapy, rapid clinical progressing, first-line immunotherapy containing HDMP can prolong PFS and will create an opportunity for patients to participate in clinical trials of novel drugs.

Objective: To assess the effectiveness in optimizing resources and shortening critical children's waiting time in pediatric emergency department (PED) with five-level pediatric emergency triage system (PETS). Methods: This retrospective study was conducted in the First Affiliated Hospital of Xiamen University after PETS was applied. The data of patients who visited the pediatric emergency department from January 2015 to December 2017 were collected and analyzed, including age, sex, diseases, visiting time, triage rate and destination. Results: A total of 375 985 patients were included, among whom males were 225 308 (59.9%) and females were 150 677 (40.1%), all younger than 14 years of age. The number of critical cases (level â , level â ¡ and level â ¢) was increased from 4 719 (3.7%) in 2015, 12 209 (10.2%) in 2016 to 16 188 (12.7%) in 2017. The number of non-critical patients (level â ¤) decreased year by year, as from 98 213 (76.8%) in 2015 to 75 210 (62.6%) in 2016 and 78 857 (61.7%) in 2017. The patients who classified as level â or levelâ ¡according to the PETS were seen immediately by physician (n=1855, 0.5%). Overall, 119 738 patients (98.3%) who were classified as level â ¢ or level â £ could be seen by physician in a timely manner according to triage guidelines, while 2 112 patients (1.7%) could not. The mean waiting time was 9.09 min in level â ¢, 17.7 min in level â £, and 55.76 min in level â ¤ patients, respectively. The critical cases admitted to the intensive care units were 175 (36.2%) in 2015, 350 (62.8%) in 2016 and 374 (66.2%) in 2017. The etiologies were respiratory diseases (73.3%), gastrointestinal diseases (15.8%) and infectious diseases (3.1%). Conclusion: The application of PETS could optimize emergency resources and shorten the waiting time of critically ill children.

BACKGROUND: This study was designed to determine whether transport of a paediatric inpatient in a children's ride-on toy car has an effect on perioperative levels of anxiety compared with transport on a hospital gurney with or without oral midazolam premedication. METHODS: In this prospective study, 108 children aged 2-5 yr with congenital heart disease and undergoing first surgical correction were randomly allocated to one of three groups: Group C (transport in a children's ride-on car), Group G (transport on a gurney without premedication), or Group M (transport on a gurney and received premedication of oral midazolam 0.5 mg kg-1). The modified Yale Preoperative Anxiety Scale-Short Form and parent-recorded anxiety VAS were applied to evaluate anxiety in the following time points: pre-anaesthesia visit (the day before surgery), upon getting in the ride-on car or on the gurney in the ward, upon arriving in the preoperative holding area, at the moment of leaving from the holding area to the operating room (OR) (coincided with separation from parents), at the time after entering the OR, and at the time just before anaesthesia induction. RESULTS: Children in Group C exhibited significantly lower levels of anxiety from the time they got into the ride-on car until the time they entered the OR, compared with the other two groups (P<0.001). The subjects in Group C had similarly low anxiety levels to those in the Group M at the time before induction (P=0.914). CONCLUSIONS: Transport in a ride-on toy car can relieve preoperative anxiety in preschool children undergoing surgery to a comparable degree as midazolam. CLINICAL TRIAL REGISTRATION: ChiCTR-IOR-17012791.

Objective: To evaluate the prognostic value of lymphocyte-to-monocyte ratio (LMR) in angioimmunoblastic T cell lymphoma (AITL). Methods: Data of 64 patients diagnosed as AITL at the First Affiliated Hospital of Nanjing Medical University between June 2009 and July 2017, were analyzed retrospectively. Receiver Operator Characteristic (ROC) curve was used to calculate the cutoff value of LMR to divide this cohort of patients into high and low LMR groups. Characteristics between groups were compared by Pearson Chi-square or Fisher exact tests. Kaplan-Meier method and Cox regression were performed to probe prognostic factors associated with progression-free survival (PFS) and overall survival (OS). Results: A total of 64 cases [39 cases male and 25 ones female with the median age of 63 (29-89) years old] were enrolled. The cutoff value of LMR was 3.07. Patients with low LMR showed inferior PFS (9 months vs 13 months, P=0.044) and OS (16 months vs not reached, P=0.014), respectively than those without low LMR during a median follow-up of 33 months (5 to 103 months). Multivariate analysis showed that low LMR was an independent prognostic factor associated with poor outcomes (HR=0.48, 95% CI 0.26-0.92 for PFS, P=0.027; HR=0.38, 95% CI 0.18-0.82 for OS, P=0.013, respectively). Subgroup analysis showed that patients with low LMR and under the situation of high score of Prognostic Index for peripheral T-cell lymphoma, Unspecified (PIT) (2-4) had shorter PFS and OS (P=0.013 and P=0.031, respectively). But in low score of PIT (0-1) group, low LMR seemed to play almost no effects on PFS and OS (P=0.949 and P=0.238, respectively). Conclusions: The disease risk status of patients could be initially assessed according to PIT score and LMR level. Low LMR was demonstrated to be able to predict poor outcome in AITL.

Objective: To analyze the clinical characteristics, treatment and prognosis of primary gastric lymphomas (PGL). Methods: A retrospective study was conducted in 124 cases of PGL from July 2009 to January 2016 in our hospital, and the clinical records, pathological and immunohistochemical features were analyzed. The relationship between different factors at diagnosis and prognosis were studied. Results: 124 cases of PGL included 93 diffuse large B cell lymphoma (DLBCL) patients, 25 mucosa associated lymphoid tissue (MALT) lymphoma cases, 1 mantle cell lymphoma, 4 peripheral T-cell lymphoma-not otherwise specified, and 1 extra-nodal NK/T-cell lymphoma-nasal type. Of the 93 primary gastric DLBCL (PG-DLBCL) patients, the germinal center B cell-like (GCB) DLBCL were 45 cases, non-GCB DLBCL were 48 cases. 10 cases (10.8%) of 93 PG-DLBCL were transformed from gastric MALT, and 7 cases (7.5%) have bone marrow involvement. Evidence of Helicobacter pylori infection was detected in 21 cases (51.2%) of 41 DLBCL patients and in 10 cases (43.5%) of 23 MALT patients. Univariate analysis revealed that clinical stages (P=0.002) , B symptoms (P=0.001) , international prognostic index (IPI) score (P<0.001) , anemia (P<0.001) , low level of serum albumin level (P=0.001) , high level of lactate dehydrogenase (LDH) (P<0.001) , high ß2-microglobulin (P=0.003) , chemotherapy uncombined with rituximab (P=0.006) were factors affecting progression-free survival (PFS). Multivariate Cox regression analysis indicated that clinical stages (HR=5.113, 95% CI 1.087-24.048, P=0.039) and LDH (HR=5.111, 95%CI 1.651-15.827, P=0.005) were independent poor prognosis factors affecting PFS. In the non-GCB group, the PFS was significantly extended (P=0.013) , the OS has no statistical significance (P=0.764). The PFS was significantly shortened in MALT transformed to DLBCL compared with MALT lymphoma patients (P=0.016) , but have no statistical significance compared with DLBCL patients (P=0.373). Conclusions: The types of DLBCL and MALT are more common in PGL. PG-DLBCL is a highly heterogeneous malignant tumor, and advanced clinical stages and high LDH value are associated with poor outcome.
