This study preliminarily investigated the mechanism by which chloroquine (CQ) relieves acute lung injury (ALI) complicated in acute hemorrhagic necrotizing pancreatitis (AHNP). Sixty male Wistar rats were randomized into sham-operated group (group A, n=10), AHNP group (group B, n=10), L-arginine-treated group (group C, n=10), L-N-nitro-L-arginine methyl ester (NAME)-treated group (group D, n=10), CQ-treated group (group E, n=10) and CQ+L-NAME-treated group (group F, n=10). TLR4 expression was measured by using real time-PCR and Western blotting respectively. The results showed that, in the group B, the expression of TLR4 and the levels of TNF-α and IL-6 in the lungs were significantly increased, and the nitric oxide (NO) concentration was reduced, as compared with those in the group A (P<0.05 or P<0.01). Lung injury was aggravated with the increased expression of TLR4. When the inhibitor and stimulator of TLR4, namely L-Arg and L-NAME, were added respectively, lung injury was correspondingly relieved or aggravated (P<0.05 or P<0.01). In the group E, TLR4 expression was substantially lower and NO concentration higher than those in the group B (P<0.05 or P<0.01). However, in the group F, NO concentration was markedly decreased, and the inhibitory effect of CQ on TLR4 expression and the relief of lung injury were weakened when compared with those in the group E (P<0.05 or P<0.01). It was concluded that TLR4 may play an important role in the pathogenesis and development of ALI complicated in AHNP. CQ could relieve ALI by decreasing the TLR4 expression and increasing the NO release.

BACKGROUNDCentral nervous system leukemia (CNSL) is an important relapse in children with acute lymphoblastic leukemia (ALL). We investigated the possible role of endogenous hydrogen sulfide (H(2)S) of cerebrospinal fluid (CSF) in predicting CNSL.
METHODSFrom August 2008 to December 2010, 380 children were enrolled in this study at Shijitan Hospital, China. These children were from 2 to 16 years old, and the median age was 6.5 years. They were divided into a CNSL group (7 cases), a leukemia group (307 cases), a non-leukemia group (26 cases) and a healthy group (40 children). CSF specimens were obtained from conventional lumbar punctured, then centrifuged and supernatants preserved for H(2)S detection. Leukemic cells precipitates from CSF were found in three cases, the hCSE and hCBS mRNA expression was detected by reverse transcription polymerase chain reaction (RT-PCR), and H(2)S levels in serum were also measured. The receiver operating characteristic (ROC) curve and area under curve (AUC) were used to assess the predictive diagnosis role of CSF H(2)S in children with ALL and CNSL.
RESULTSThe serum H(2)S contents of the CNSL and leukemia groups were (96.98 ± 15.77) µmol/L and (93.35 ± 17.16) µmol/L respectively, much higher than those of healthy, (44.29 ± 2.15) µmol/L, and non-leukemia, (46.32 ± 6.54) µmol/L, groups (P < 0.01). Compared with the leukemia group, CSF H(2)S content of the CNSL group was significantly high (P < 0.01). Meanwhile, in contrast to the non-leukemia group, CSF H(2)S contents of the CNSL and leukemia groups were both significantly increased (P < 0.01). In addition, leukemic cells from CSF precipitations could express CBS and CSE mRNA. Furthermore, the ROC analysis showed the UAC was 0.929 (95%CI: 0.857 - 1.000), and the optimum cut-off value of CSF H(2)S was 12.08 µ mol/L, and the sensitivity and specificity were 83.3% and 97.2% respectively.
CONCLUSIONSCSF H(2)S contents were significantly increased in children with CNSL. After treatment, H(2)S contents were decreased subsequently. Therefore, we speculated that H(2)S levels of CSF would predict CNSL in ALL children.

OBJECTIVE:
To investigate the risk factors for recurrence of medulloblastoma (MB) within 2 years and their influence on progression-free survival (PFS).
METHODS:
A retrospective analysis was performed for the clinical data of 123 children with MB who were admitted from January to December, 2017. According to the presence or absence of recurrence, they were divided into recurrence group with 30 children and non-recurrence group with 93 children. The risk factors for recurrence within 2 years were analyzed, and PFS was compared between the children with different risk factors.
RESULTS:
Large-cell/anaplastic type and M stage were risk factors for MB recurrence within 2 years. The risk of recurrence in the children with M+ MB was 3.525 times that in those with M0 MB, and the risk of recurrence in the children with large-cell/anaplastic MB was 3.358 times that in those with classic MB (P<0.05). The survival analysis showed that the median PFS time was 20 months in the children with M+ MB, and the 20-month PFS rate was 50% ± 11% in the children with M+ MB and 81% ± 5% in those with M0 MB (P<0.05). The 20-month PFS rate was 80% ± 5% in the children with classic MB, 65% ± 10% in those with desmoplastic/nodular MB, 86% ± 13% in those with MB with extensible nodularity, and 36% ± 20% in those with large-cell/anaplastic MB (P<0.05).
CONCLUSIONS
Recurrence is an important influencing factor for the prognosis of MB, and M+ stage and large-cell/anaplastic MB are risk factors for recurrence. Children with such risk factors tend to have a low PFS rate.

OBJCTIVE:
To study the clinical effect of surgery combined with chemotherapy and radiotherapy in children with central primitive neuroectodermal tumor (cPNET), as well as the risks factors for poor prognosis.
METHODS:
A retrospective analysis was performed for the clinical data of 42 children who were diagnosed with cPNET from June 2012 to September 2018.
RESULTS:
The 42 children had a median overall survival (OS) time of 2.0 years and a median event-free survival (EFS) time of 1.3 years; the 1-, 3-, and 5-year OS rates were 76.2%±6.6%, 41.4%±8.7%, 37.3%±8.8% respectively, and the 1-, 3-, and 5-year EFS rates were 64.3%±7.4%, 32.7%±8.0%, 28.0%±8.1% respectively. The univariate analysis showed that there were significant differences in the OS and EFS rates among the children with different patterns of surgical resection, chemotherapy cycles, and risk grades (P<0.05), and there was also a significant difference in the OS rate between the children receiving radiotherapy and those not receiving radiotherapy (P<0.05). The multivariate Cox regression analysis showed that chemotherapy cycles and risk grade were independent influencing factors for EFS and OS rates (P<0.05). The EFS and OS rates increased with the increase in chemotherapy cycles and the reduction in risk grade.
CONCLUSIONS
Multimodality therapy with surgery, chemotherapy, and radiotherapy is an effective method for the treatment of cPNET in children. Early diagnosis and treatment and adherence to chemotherapy for as long as possible may improve EFS and OS rates.

OBJECTIVETo evaluate the efficacy and safety of oxymatrine in the treatment of chronic hepatitis B.
METHODSA multicenter randomized double-blind placebo-controlled trial was conducted. A total of 144 patients with chronic hepatitis B entered the study for 52 weeks; of them 72 received oxymatrine, and 72 received a placebo. Before and after the treatment, clinical symptoms, liver function, serum hepatitis B virus markers, and adverse drug reactions were observed.
RESULTSIn 144 patients, 14 were dropped and excluded due to inconsistencies in the included standard. Therefore, the efficacy and safety of 130 patients were analyzed. After being treated for 52 weeks, 70.77% of the patients in the study group had a normal ALT level, and in 43.08% and 33.33% their HBV DNA and HBeAg became negative. In the placebo group, 39.68% had normal ALT level, and 12.31% and 3.33% had their HBV DNA and HBeAg become negative. The rates of complete response and partial response in the oxymatrine group were 23.08% and 58.46%, and in the placebo group they were 3.08% and 44.62%. They were significantly higher in the oxymatrine group than in the placebo group. In the oxymatrine treated patients, 12 weeks after its withdrawal, 60.00% had a normal ALT level, 41.54% and 23.33% had both HBV DNA and HBeAg negative. In the placebo group, 31.75% had a normal ALT level, 3.08% and 1.67% had both HBV DNA and HBeAg negative. The rates of complete response and partial response in the oxymatrine group were 21.54% and 47.69%, and in the placebo group they were 0 and 41.54%. They were significantly higher in the study group than in the placebo group. The adverse reaction rates of oxymatrine in the study and the placebo group were 7.69% and 6.15%, respectively, but there was no statistical significant difference between them.
CONCLUSIONOxymatrine is an effective and safe agent for the treatment of chronic hepatitis B.

OBJECTIVE:
To investigate the effect of bevacizumab in the treatment of children with optic pathway glioma (OPG).
METHODS:
A retrospective analysis was performed for the clinical data of 30 children with OPG who underwent chemotherapy. According to whether bevacizumab was used, they were divided into conventional chemotherapy (carboplatin, vincristine and etoposide) group with 12 children and combined chemotherapy (bevacizumab, carboplatin, vincristine and etoposide) group with 18 children. The children were followed up to 6 months after chemotherapy, and the two groups were compared in terms of visual acuity and tumor size before and after chemotherapy and adverse reactions during chemotherapy.
RESULTS:
The combined chemotherapy group had a significantly higher proportion of children achieving tumor regression than the conventional chemotherapy group (P<0.05), while there were no significant differences between the two groups in the proportion of children with improved visual acuity or adverse reactions (P>0.05). No chemotherapy-related death was observed in either group.
CONCLUSIONS
Bevacizumab combined with conventional chemotherapy can effectively reduce tumor size. Compared with conventional chemotherapy, such combination does not increase adverse reactions and can thus become a new direction for the treatment of OPG in children.

Objective To construct a regulatory network of competing endogenous RNA(ceRNA)with prognostic value for bladder urothelial carcinoma(BLCA),and analyze the relationship between key messenger RNA(mRNA)and immune function.Methods The UCSC Xena database was used to download mRNA expression data from 404 BLCA patients and 28 normal individuals and key mRNAs were screened by differential analysis.ENCORI database was utilized to search microRNAs(miRNAs)that bind to key mRNAs and all long non-coding RNAs(LncRNAs)that bind to miRNAs.The expression data of miRNA and LncRNA were downloaded from TCGA database,co-expression analysis was performed to identify key mRNA with all miRNAs and miRNA with all LncRNAs,and thus key miRNAs and LncRNAs were screened out.Survival analysis was conducted based on the differences in expression levels of these key mRNAs,miRNAs,and LncRNAs between tumor patients and normal individuals,and finally a ceRNA regulatory network was constructed.The correlation between key mRNAs and immune cells,immune checkpoints(CD274,PDCD1 and CTLA4),and immune cell marker genes(IG)was analyzed using the TIMER 2.0 database.Results A total of 22 key mRNAs were screened,with the most significant difference being proline 3-hydroxylase 4(P3H4).The expression of P3H4 in patients with BLCA was high,and survival time was shorter in patients with high expression.A sum of 33 miRNAs and 14 LncRNAs were screened using the key mRNAs as the central link.Through co-expression analysis and survival analysis,hsa-miR-151a-3p and MIR100 HG were identified as the key miRNA and key LncRNA with prognostic value.The differences in the above analysis results were statistically significant(all P<0.05).Based on these findings,a ceRNA regulatory network consisting of 1 mRNA,1 miRNA,and 1 LncRNA was constructed.Immunoassay firstly revealed a significant positive correlation between double positive T cells and P3H4 expression in the tumor microenvironment of BLCA.Moreover,there were 3 types of immune cells(tumor-associated neutrophils,and tumor-associated macrophages,dendritic cells),3 immune checkpoints(CD274,PDCD1,CTLA4),and 15 IGs with significant correlation with P3H4.These differences were statistically significant(all P<0.01).Conclusion This study could help to reveal the progression mechanism of BLCA.The constructed ceRNA network and immune analysis can offer new insights into potential biological targets and immunotherapy directions for the diagnosis,treatment,and prediction of BLCA patients.
