Abstract
Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ2=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ2=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ2=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ2=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Abstract
Atherosclerosis is a major risk factor for type 2 diabetes (T2D) mortality. We aim to investigate the changes in miR-21, miR-122, miR-33a and miR-3064-5p in circulation and the liver of ApoE-/- mice with streptozocin (STZ)-induced T2D. Twenty 5-week-old male ApoE-/- mice were randomly assigned to the control (n = 10) and T2D group (n = 10) and intraperitoneally injected with a citrate buffer and streptozotocin (STZ) (40 mg/kg BW) once a day for three consecutive days. The successfully STZ-induced T2D mice (n = 5) and control mice (n = 5) were then fed with a high-fat diet (HFD) for 34 weeks. Compared to the control mice, ApoE-/- mice with STZ-induced T2D had slower (p < 0.05) growth, increased (p < 0.05) total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), decreased (p < 0.05) high-density lipoprotein cholesterol (HDL-C) in serum, reduced (p < 0.05) TC and sterol regulatory element-binding protein-2 (Srebp-2), elevated (p < 0.05) ATP-binding-cassette-transporter-A1 (Abca1) in the liver, aggravated (p < 0.05) atherosclerotic lesions in the aorta, downregulated (p < 0.05) miR-21 and miR-33a, and upregulated (p < 0.05) miR-122 and miR-3064-5p in serum and the liver. In addition, the aortic lesions showed a positive correlation with miR-122 (r = 1.000, p = 0.001) and a negative correlation with miR-21 (r = −1.000, p = 0.001) in ApoE-/- mice with T2D. In conclusion, T2D-accelerated atherosclerosis correlates with a reduction in miR-21 and miR-33a and an elevation in miR-122 and miR-3064-5p in circulation and the liver of ApoE-/- mice.

Abstract
Even to date, Oral squamous cell carcinoma (OSCC), which is one of the most common malignancies worldwide, is still a major public health problem. The cellular mechanisms underlying development of OSCC are poorly understood. Lipid rafts-associated proteins not only serve as a docking platform for protein sorting and membrane trafficking, but also coordinate signaling molecules at cell membrane to mediate intracellular responses, which makes them susceptible to be subverted by cancer cells. Although Flotillin-1 has been discovered for decades, its potential role in OSCC development is largely unknown. In current study, we demonstrate that Flotillin-1 is highly expressed in OSCC cell lines compared to normal oral epithelial cells. Modulation of Flotillin-1 expression via transfection with Flotillin-1 expression vector or shRNA showed that Flotillin-1 has a clearly positive impact on cell growth and motility in KB and/or Tca8113 cell lines. These observations were further supported by using mice or zebrafish tumor xenograft models. Mechanistic study indicated that Flotillin-1 expression activates NF-κB signaling pathway by enhancing phosphorylation of p65 and IκBα, and translocation of p65 into nucleus. Furthermore, inhibition of EGFR by AG1478 markedly repressed Flotillin-1-induced activation of NF-κB signaling pathway. Our studies suggested that Flotillin-1 plays an important role in OSCC development, and might be a potential therapeutic target for OSCC.

Abstract
Our newly-designed computer-controlled equipment for delivering volatile anesthetic agent uses the subminiature singlechip processor as the central controlling unit. The variables, such as anesthesia method, anesthetic agent, the volume of respiratory loop, age of patient, sex, height, weight, environment temperature and the grade of ASA are all input from the keyboard. The anesthetic dosage, calculated by the singlechip processor, is converted into the signals controlling the pump to accurately deliver anesthetic agent into respiratory loop. We have designed an electrocircuit for the equipment to detect the status of the pump's operation, so we can assure of the safety and the stability of the equipment. The output precision of the equipment, with a good anti-jamming capability, is 1-2% for high flow anesthesia and 1-5% for closed-circuit anesthesia and its self-detecting working is reliable.

Abstract
OBJECTIVE To investigate the existance of Epstein-Barr virus (EBV) and papilloma virus(HPV) in sinonasal malignant neoplasms. METHOD EBV and HPV (including HPV6,11,16,18,33) gene were detected in paraffin-embedded tissues with polymerase chain reaction(PCR) from 32 cases of sinonasal malignant neoplasms. RESULT EBV was detected in 12(37.5%), HPV in 21(65.6%); The coinfection of EBV and HPV was found in 6 cases with stage III-IV by TNM; 10 cases of nasal polyps contained neither EBV nor HPV. CONCLUSION Like HPV, there may be relationship between EBV and sinonasal malignant neoplasms. The coinfection of EBV and HPV is related to stage III-IV by TNM of sinonasal malignant neoplasms.

Abstract
AIM To study the effects of artesunate (dihydroartemisinine-12-alpha-succinate, Art) on immune function in mice. METHODS Hemolysin concentration was determined by colorimetric method. Serum IgG and C3 contents were measured by single immunodiffusion method. Percentage of lymphocyte transformation, phagocytosis percentage and phagocytic index were counted under microscope. RESULTS Art im 75 mg kg-1 bid x 7 d decreased the humolysin-forming capacity and levels of serum IgG of mice sensitized with sheep red blood cell. The serum complement 3 level rose remarkably, when Art was given im to Plasmodium berghei-infected mice. Art enhanced the PHA-induced lymphocyte transformation rate (in vivo) in mice and increased the weight of spleen but reduced that of thymus in mice. Art elevated the DNFB-induced delayed-type hypersensitivity. Art im 75 mg kg-1 bid x 5 d reduced the percentage of phagocytosis of peritoneal macrophages and the phagocytic index. CONCLUSION Art suppressed the humoral immune responses but enhanced the cell-mediated immunity.
