Objective To investigate the clinical characteristics and the course of diagnosis and therapy of asparaginase associated pancreatitis (AAP) in adults, in order to improve the ability of diagnosis and treatment.Methods Data of 384 cases of acute lymphoblastic leukemia (ALL) who received treatment in Department of Hematology, Zhejiang Hospital, and Department of Hematology, Second Hospital Affiliated to Wenzhou Medical University from January 2009 to June 2015 was retrospectively analyzed.All patients were given multi-drug chemotherapy including PEG-asparaginase or L-asparaginase, the incidence of AAP, clinical manifestations, diagnosis, treatment and prognosis were analyzed.Results Among the 384 cases, 18 patients developed AAP, and the incidence of AAP was 4.7％, including 13 cases of mild AAP (MAAP), 5 cases of severe AAP (SAAP).Sixteen cases of AAP occurred during the induction-remission treatment phase, 2 cases during the maintenance-intensification phase.The major manifestations of AAP were abdominal pain, and increased serum amylase and lipase.After treatment, abdominal pain of MAAP patients alleviated, serum amylase and lipase obviously decreased, and re-use of PEG-Asparaginase or L-Asparaginase was not associated with the recurrence of AP.Levels of serum amylase and lipase in 5 cases of SAAP repeatedly increased, 1 case died of severe infection, cyst rupture and hemorrhage.Conclusions Adults patients with ALL present with abdominal pain during chemotherapy of aspargase should consider the possibility of AAP, the measurement of serum amylase and serum lipase should be strengthened, in addition, ultrasound and CT scanning may be helpful for early diagnosis and treatment of AAP, and improve the prognosis.

Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme in the salvage pathway for the biosynthesis of nicotinamide adenine dinucleotide (NAD+) from nicotinamide. NAMPT is also a cytokine that inhibits the apoptosis of neutrophils under various inlfammatory stimuli, regulates various diseases and closely associates with the progression and prognosis of cancers. However, it is still not clear whether the cytokine-like function of NAMPT is interrelated with the biosynthesis enzyme activity of NAD+. This article aims to provide novel insights for inflammation and cancers treatment by reviewing the function of NAMPT in inflammation, carcinogenesis, cancer progression and its inhibitors, APO866/FK866.

Objective:To investigate the expression of pre-B-cell leukemia homeobox 3 (PBX3) and the phosphatase and tensin homology deleted on chromosome 10 (PTEN) in cervical cancer and its relationship with the clinicopathologic characteristics and prognosis.Methods:Cervical cancer tissues and adjacent tissues of 85 patients with cervical cancer admitted to Xianlin Gulou Hospital from June 2014 to December 2018 were collected and the expression levels of PBX3 and PTEN were detected by immunohistochemistry. The univariate analysis and Logistic regression model were used to analyze the relationship between the expression levels of PBX3, PTEN and clinicopathologic features. Kaplan-Meier survival curve was used to analyze the relationship between the expression levels of PBX3, PTEN and prognosis.Results:The positive expression rate of PBX3 protein in cervical cancer tissues was higher than that in adjacent tissues: 38.82%(33/85) vs. 25.53%(20/85); the positive expression rate of PTEN protein was lower than that in adjacent tissues: 36.47%(31/85) vs. 98.82%(84/85), and there were significant differences ( P<0.05). The univariate analysis showed that the expression levels of PBX3 and PTEN were associated with clinical stages, degree of tumor differentiation, lymph node metastasis, vascular invasion, and degree of tumor invasion ( P<0.05). The multiple Logistic regression model showed that the clinical stages, tumor differentiation and lymph node metastasis were independent influencing factors for the positive expression of PBX3 or PTEN in cervical cancer tissues ( P<0.05). While 45.45%(15/33) of patients with positive PBX3 expression died, with a median survival of 31 months, and 25.00% (13/52)of patients with negative expression died, with a median survival of 38 months. Kaplan-rank test showed that the survival time in the patients with positive PBX3 expression and in the patients with negative expression had significant difference ( P=0.025). While 22.58%(7/31) of patients with positive PTEN expression died, with a median survival of 39 months, and 38.89%(21/54) of the patients with negative expression died, with a median survival time of 33 months. Kaplan-rank test showed that the survival time in the patients with positive PTEN expression and in the patients with negative expression had significant difference ( P=0.035). Conclusions:The expression of PBX3 is up-regulated and PTEN is down-regulated in cervical cancer. The expression levels of PBX3 and PTEN are related to clinical stage, tumor differentiation and lymph node metastasis. The prognosis of the patients with positive PBX3 expression is worse than that of the patients with negative expression, and the prognosis of the patients with positive PTEN expression is better than that of the patients with negative expression.

CONCLUSIONS:The method is simple,accurate and reliable,and can provide ref-erence for quality control of Heye granule.

Objective To investigate the impact ofα?lipoic acid(ALA)treatment on sepsis?induced acute kidney injury in rats and explore the mechanisms. Methods A total of 32 male SD rats were randomized into 4 groups:normal control group(group A),ALA?treated control group (group B),sepsis group(group C)and sepsis with ALA treated group(group D). Group A and B underwent sham operation,while CLP operations were conducted in group C and D. Rats in both group B and group D were then administered with 200 mg/kg ALA by oral gavage immediately after the surgical procedure. Twenty?four hours after the surgical procedure blood samples were obtained for the evaluation of creatinine,BUN,TNF?α,IL?6 and IL?1β. Rat kidneys were rapidly removed for PAS stain. Western blot was employed to determine the expression of NF?κB. Results Pathologi?cal changes of kidney were induced by sepsis and the level of creatinine,BUN,TNF?α,IL?6 and IL?1βwere significantly increased by 178%,66%, 55%,114%and 110%(P<0.01). respectively;simultaneously the phosphorylation and nuclear expression of NF?κB p65 in kidney tissues were significantly increased by 144%and 102%(P<0.01). Sepsis?induced acute kidney injury also significantly reduced the expression of IκBαby 61%(P<0.01). These changes were significantly suppressed by early ALA treatment. Compared with C group,the level of creatinine,BUN,TNF?α,IL?6 and IL?1βwere significantly decreased by 48%,26%,25%,37%and 40%(P<0.05),respectively,and the relative expression of IκBαwas increased by 103%(P<0.05). Conclusion The present study demonstrated that ALA can suppress the activation of NF?κB,thus ameliorat?ing sepsis?related acute kidney injury.

Objective To prepare and explore the pharmacokinetic parameters for ~ 99 Tc~ m -ASON-EGF in healthy rabbits. Methods ~ 99 Tc~ m -ASON-EGF was prepared according to previous methods and its changes of concentration in blood were measured by radioactivity counts per minute. The experimental data were dealt with by 3p97 software and its true compartment model was estimated by AIC value, R~ 2 value, the 1/c and F test. Subsequently, its half-life of distribution (T_ 1/2 ?), half-life of elimination (T_ 1/2 ?), central compartment volume of distribution (Vc), total apparent volume of distribution (Vd) and total rate of clearance (CL) were calculated by the software. Finally, the binding rate of plasma protein was determined by trichloroacetic acid precipitation. Results The best model of ~ 99 Tc~ m -ASON-EGF in vivo was two-compartment model and its T_ 1/2 ?, T_ 1/2 ?, Vc, Vd and CL were 5.28 min, 89.23 min, 67.8 ml, 915.6 ml and 7.1 ml/min respectively. After being incubated with fresh plasma for 1.5 h, its binding rate was 10.69%. Conclusion Its process of transportation in healthy rabbits is fitted to two-compartment model and the pharmacokinetic properties are desirable.

Objective To discuss the incidence, clinical features, diagnostic methods, treatment and prognostic factors of Hodgkin lymphoma of breast. Methods The clinical data, diagnosis, treatment and prognosis of one male patient diagnosed as Hodgkin lymphoma of breast were retrospectively analyzed, and literatures were reviewed. Results The 71-year-old male patient had a main physical sign of a local painless lump in breast. The lump increased progressively, associated with generalized lymphadenopathy, skin itching and sweats. Pathologic results showed the diagnosis of classical Hodgkin lymphoma (Ann Arbor stage: ⅢEB). The patient eventually died after 7 months following the combined chemotherapy. Conclusions Hodgkin lymphoma of breast is a rare disease lacking in specific clinical manifestations. It is difficult to clarify the diagnosis before operation, and its definite diagnosis largely depends on pathological and immunohistochemical examination. The combination of chemotherapy with radiotherapy may have a favorable efficacy, with the poor diagnosis.

Objective To evaluate effects of downregulation of glucose?6?phosphate dehydrogenase(G6PD) expression on proliferation and cell cycle distribution of cutaneous squamous cell carcinoma(CSCC)cells. Methods Western blot analysis was performed to measure the protein expression of G6PD in normally cultured human HaCaT keratinocytes, SCL?1 and A431 CSCC cells. When A431 cells grew to 85%-90%confluence, a small interfering RNA (siRNA)targeting G6PD(G6PD?siRNA group)and a negative control siRNA(siRNA control group)were transfected into them separately, and untransfected A431 cells served as the untransfected group. CCK?8 assay was performed to evaluate proliferative activity of the A431 cells on days 0, 1, 2, 3 and 4 after transfection, Western blot analysis to measure G6PD, cyclin D1 and CDK4 protein expressions in A431 cells, and flow cytometry to analyze cell cycle distribution in A431 cells after 48 hours of additional culture. Results The protein expression of G6PD was significantly higher in normally cultured SCL?1 cells(0.308 ± 0.023)and A431 cells(0.643 ± 0.046)than in HaCaT cells(0.100 ± 0.019, both P<0.05), and significantly higher in A431 cells than in SCL?1 cells(P<0.05). The G6PD?siRNA group showed significantly decreased protein expressions of G6PD, cyclin D1 and CDK4(0.134 ± 0.027, 0.154 ± 0.017 and 0.166 ± 0.017, respectively)compared with the untransfected group(0.425 ± 0.029, 0.344 ± 0.024 and 0.330 ± 0.020 respectively)and siRNA control group(0.444 ± 0.033, 0.350 ± 0.027 and 0.348 ± 0.018 respectively) (all P<0.05). Besides, the G6PD?siRNA group showed significantly decreased cellular proliferative activity on days 1-4 compared with the siRNA control group and untransfected group(all P<0.001), while there were no significant differences between the untransfected group and siRNA control group at any of the time points (all P > 0.05). Compared with the untransfected group and siRNA control group, the G6PD?siRNA group showed significantly higher proportions of A431 cells in G0/G1 phase(both P < 0.001), but significantly lower proportions of A431 cells in S phase(both P<0.001). Conclusion G6PD may play important roles in the regulation of proliferation and cell cycle distribution of CSCC cells.

A 46-year-old male patient developed scatterred reddish-brown plaques and nodules on the back 6 years prior to the presentation. Then, the lesions gradually spread to the axillary fossa and protothorax, and became indurated with slight itching in winter. Laboratory examination revealed hypergammaglobulinemia. Computed tomography(CT)scan showed multiple nodular or patchy shadows in both lungs, lymphadenectasis in axillary, mediastinal and inguinal regions, and spleen enlargement. Histopathological examination of skin lesions showed granulomatous infiltrates with plenty of lymphocytes, histiocytes and mature plasma cells in the middle and lower dermis with the presence of lymphoid follicle-like structures, but no cell atypia was observed. Immunohistochemical study showed positive staining for CD38, CD138, CD79a, κ and λ light chains. According to clinical manifestations and laboratory examination results, the patient was diagnosed with cutaneous and systemic plasmacytosis.
