POEMS syndrome is a rare condition associated with plasma cell disorders, and it often involves multiple systems and has diverse clinical manifestations. This article reports two cases of POEMS syndrome with hepatosplenomegaly as the initial manifestation. During the course of the disease, the patients presented with lower limb weakness, hepatosplenomegaly, lymph node enlargement, ascites, hypothyroidism, positive M protein, and skin hyperpigmentation, and 18F-FDG PET-CT imaging revealed bone lesions mainly characterized by osteolytic changes and plasma cell tumors. There was an increase in the serum level of vascular endothelial growth factor. The patients were finally diagnosed with POEMS syndrome, and the symptoms were relieved after immunomodulatory treatment.

BACKGROUND:
Angiogenesis is described as a complex process in which new microvessels sprout from endothelial cells of existing vasculature. This study aimed to determine whether long non-coding RNA (lncRNA) H19 induced the angiogenesis of gastric cancer (GC) and its possible mechanism.
METHODS:
Gene expression level was determined by quantitative real-time polymerase chain reaction and western blotting. Cell counting kit-8, transwell, 5-Ethynyl-2'-deoxyuridine (EdU), colony formation assay, and human umbilical vein endothelial cells (HUVECs) angiogenesis assay as well as Matrigel plug assay were conducted to study the proliferation, migration, and angiogenesis of GC in vitro and in vivo . The binding protein of H19 was found by RNA pull-down and RNA Immunoprecipitation (RIP). High-throughput sequencing was performed and next Gene Ontology (GO) as well as Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis was conducted to analyze the genes that are under H19 regulation. Methylated RIP (me-RIP) assay was used to investigate the sites and abundance among target mRNA. The transcription factor acted as upstream of H19 was determined through chromatin immunoprecipitation (ChIP) and luciferase assay.
RESULTS:
In this study, we found that hypoxia-induced factor (HIF)-1α could bind to the promoter region of H19, leading to H19 overexpression. High expression of H19 was correlated with angiogenesis in GC, and H19 knocking down could inhibit cell proliferation, migration and angiogenesis. Mechanistically, the oncogenic role of H19 was achieved by binding with the N 6 -methyladenosine (m 6 A) reader YTH domain-containing family protein 1 (YTHDF1), which could recognize the m 6 A site on the 3'-untransated regions (3'-UTR) of scavenger receptor class B member 1 (SCARB1) mRNA, resulting in over-translation of SCARB1 and thus promoting the proliferation, migration, and angiogenesis of GC cells.
CONCLUSION
HIF-1α induced overexpression of H19 via binding with the promoter of H19, and H19 promoted GC cells proliferation, migration and angiogenesis through YTHDF1/SCARB1, which might be a beneficial target for antiangiogenic therapy for GC.

Objective:
To investigate the role of nucleotidebinding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome in hyperalgesia induced by temporomandibular joint osteoarthritis (TMJOA) in rats.
Methods :
Twenty 6-week-old male SD rats were randomly divided into NS group and MIA group.The rat model of TMJOA was established by injection monosodium iodoacetate ( MIA) into the upper cavity of temporomandibular joint (TMJ) .The changes of pain threshold in the TMJ region of rats after MIA injection were detected by Von Frey.The changes of condyle structure were observed by Hematoxylin-eosin ( HE ) and Safranin O-fast green stains.Histopathological changes of trigeminal ganglion (TG) were observed by HE stains.The expression and distribution of TG NLRP3 protein were detected by immunohistochemistry.Western blot was used to detect the protein levels of NLRP3 and interleukin (IL) -1 β in TG.The mRNA levels of NLRP3,apoptosis-associated speck-like protein (ASC) ,cysteinyl aspartate specific proteinase ( Caspase-1) ,IL-1β and IL-18 in TG were detected by quantitative real-time polymerase chain reaction ( qRT-PCR) .
Results :
Compared to saline group,the pain threshold of experimental TMJ osteoarthritis rats decreased (P<0. 05) .TMJ and TG showed obvious pathological changes.The protein and mRNA levels of NLRP3 expressed in the tissues of rats in the TMJOA group increased (P <0. 05 ) .
Conclusion
NLRP3 inflammasome may be involved in the regulation of hyperalgesia in TMJOA rats.

Objective:To summarize the clinical features, treatments and prognoses of aggressive natural killer cell leukemia (ANKL) in children.Methods:Clinical data and follow-up results were retrospectively reviewed for one hospitalized case of ANKL in June 2019.Through a literature search, the relevant items were retrieved from the databases of China National Knowledge Infrastructure, WanFang and PubMed using the Chinese and English keywords of "aggressive natural killer cell leukemia" and "children" up to December 2021.Results:This 8-year-old girl was diagnosed with ANKL by flow cytometric immunophenotype and immunohistochemical stain.Fever was the initial manifestation accompanied by sallow complexion, fatigue, enlargement of liver, spleen and lymph node and hematopenia of three lines.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed after chemotherapy.As of April 2022, the child stayed in a disease-free survival state after follow-ups for over 2 years.The literature search finally yielded 7 eligible Chinese and 10 English reports with a total of 17 pediatric ANKLs.In this group, there were fever (n=15), rash (n=1), perineal mass (n=1) and diarrhea, vomiting and other digestive tract symptoms (n=1). Six cases were misdiagnosed during an early stage of disease.4 cases received chemotherapy alone, 3 cases received chemotherapy regimen for acute lymphoblastic leukemia, 1 child died and one death occurred after received chemotherapy regimen of "cisplatin + vincristine + doxorubicin + ifosfamide". Allo-HSCT was performed in 5 patients after remission with chemotherapy and one child died from multiple organ failure at 9 months after allo-HSCT.Nine cases gave up treatment.Conclusions:ANKL has a rapid disease progression, diverse clinical manifestations, easy misdiagnosis and poor prognosis.For suspected ANKL cases, clinicians perform multiple bone perforations at multiple sites and immunophenotype by flow cytometry as soon as possible to confirm the diagnosis.Currently allo-HSCT offers a long-term survival of ANKL patients.

BACKGROUND:
With the aging of the population and the increased importance of lung cancer screening, the number of early-stage lung cancer patients has been on the rise in recent years, which can be classified into operable early-stage lung cancer and inoperable early-stage lung cancer. The most common pathological type is non-small cell lung cancer (NSCLC). Stereotactic body radiation therapy (SBRT) is the optimal treatment for inoperable early-stage NSCLC. The aim of this study was to investigate the prognosis of early-stage NSCLC patients treated with SBRT and its influencing factors in order to reduce the side effects of radiotherapy and improve the survival and quality of life.
METHODS:
Clinical data and follow-up outcomes of early-stage NSCLC patients treated with SBRT in our hospital from August 2010 to August 2020 were collected. Kaplan-Meier method was used to assess the prognosis, and the Cox proportional risk model was used for multivariate prognostic analysis.
RESULTS:
A total of 165 patients were included with a median follow-up time of 43.2 (range: 4.8-132.1) mon. The local control (LC) rates at 1-yr, 2-yr and 5-yr were 98.1%, 94.8% and 86.5% respectively. Karnofsky performance status (KPS) score greater than 80 was an independent prognostic factor for LC (P=0.02). The overall survival (OS) rates at 1-yr, 2-yr and 5-yr were 97.6%, 93.0% and 68.9% respectively. A biological equivalent dose when α/β=10 (BED10) greater than 132 Gy was an independent prognostic factor for OS (P=0.04). Progression-free survival (PFS) rates at 1-yr, 2-yr and 5-yr were 93.3%, 79.5% and 55.3% respectively. The distance metastasis free survival (DMFS) rates at 1-yr, 2-yr and 5-yr were 94.5%, 83.2% and 58.4% respectively. BED10 greater than 150 Gy was an independent prognostic factor for DMFS (P=0.02). The regional control (RC) rates at 1-yr, 2-yr and 5-yr were 98.8%, 95.4% and 87.9% respectively.
CONCLUSIONS
SBRT is effective in treating early-stage NSCLC. KPS greater than 80 is an independent prognostic factor for LC; BED10 greater than 132 Gy is an independent prognostic factor for OS; BED10 greater than 150 Gy is an independent prognostic factor for DMFS.

Objective:
This study aimed to explore the role of SGK-1 in the occurrence of temporomandibular joint(TMJ) osteoarthritis(TMJ-OA).
Methods:
Sixteen rats were randomly divided into Control group(Control group) and TMJ-OA group(TMJ-OA group), and TMJ-OA group was injected with sodium iodoacetate(MIA) intra articular cavity while Control group was injected with 0.9% sodium chloride solution. Pain behavior was assessed by measuring the head withdrawal threshold(HWT) with a von-Frey apparatus. Hematoxylin-eosin(HE) and Safranin O-fast green stains were used to observe the histological structure changes of the condyle of TMJ-OA rats. Real-time PCR was performed to exam the expression levels of mRNA of SGK-1, MMP-13, IL-1β, COX-2 in mandibular condylar cartilage(MCC). HE stain was used to observe the histological structure changes of the trigeminal ganglion(TG) of TMJ-OA rats. Real-time PCR was performed to exam the expression levels of mRNA of SGK-1, COX-2 in TG.
Results:
MIA injection induced typical OA-like lesions in the TMJ within 28 days. Administration of MIA led to the significant decrease in HWT, disordered of the condyle cartilage and subchondral bone structure, demyelination aggravated of nerve fibers in TMJ rats. Compared with rats in Control groups, the expression levels of SGK-1 in MCC and TG of rats in TMJ-OA group were upregulated.
Conclusion
In the pathological process of TMJ-OA, SGK-1 may plays an important role not only in cartilage structural damage but also in pain transmission.
