Chinese Journal of Behavioral Medicine and Brain Science 2012;21(6):564-566
ObjectiveTo explore the theoretical construct of network values and design the network values questionnaire.MethodsThis research was to design the network values questionnaire based on an open-ended inventory survey,overviews of former studies and counseling of experts.Through stratified sampling,832 college students were investigated by the network questionnaire.The data were examined by item analysis,factor analysis,reliability and validity analysis.ResultsThe network values was a multi-dimensional construct which had three factors.The three factors cumulative total explained variance was 50.719%,52.545% and 50.510%.The questionnaire's internal consistency reliability was 0.931 and 0.809-0.874 for the three subscales.The questionnaire's split-half reliability was 0.902 and 0.772-0.864 for the three subscales.ConclusionThe theoretical construct of network values is rational.The questionnaire has good reliability and validity.
2.Effects of arsenic exposure during pregnancy on maternal and neonatal health: a review
Journal of Preventive Medicine 2023;35(7):591-595
Arsenic is a toxic metalloid, which may enter the human body through a variety of routes, including drinking water, food, and air. Previous studies have shown that arsenic exposure during pregnancy may cause pregnancy complications and adverse pregnancy outcomes, and maternal arsenic levels correlate with neonatal neurodevelopment and adult health. However, the negative impact of arsenic exposure during pregnancy on maternal and child health has not been widely accepted because of inconsistent study conclusions and unclear mechanisms. Based on international and national studies pertaining to the effect of arsenic exposure during pregnancy on maternal and child health during the period between 2007 and 2022, this review describes the influencing factors and biomarkers of arsenic exposure during pregnancy, associations of arsenic exposure during pregnancy with pregnancy complications and adverse pregnancy outcomes and impact of arsenic exposure during pregnancy on neonatal neurodevelopment, and discusses the mechanisms underlying negative health effects caused by arsenic exposure during pregnancy, so as to provide the evidence for assessing the hazards of arsenic exposure during pregnancy and formulating the control strategy.

A 53-year-old man presented with prunosus nodules and plaques on the trunk and extremities for half a month and with periorbital swelling for 4 days.Hematological examination in a local hospital showed thrombocytopenia,and pulsed corticosteroid therapy did not work.On physical examination,there were splenomegaly and multiple enlarged superficial lymphnodes.Serum calcium and 1-lactate dehydrogenase (LDH)were increased to 3.12 mmol/L and 853 U/L,respectively.Serum immunofixation electrophoresis evidenced the presence of a monoclonal immunoglobulin IgM (κ chain).Positron emission tomography (PET-CT) showed abnormal uptake in multiple lymph nodes,back wall of the pharynx,and spleen.The biopsy of a nodule in the neck revealed a diffuse infiltration of numerous atypical lymphoid cells in the subcutaneous fat tissue,which were medium-sized with round nuclei,obvious nucleoli and karyokinesis, Immunophenotyping of the abnormal lymphocytes indicated positive reactions for L26,CD79a,Bcl-2,cyclin D1,multiple myeloma oncogene 1 (partly),Ki-67 (>80%),but negative for CD5,CD21,CD23,CD38,CD3,CD10,Bcl-6,CD45RO,terminal deoxynucleotidyl transferase (TdT),myeloperoxidase (MPO),CD30,anaplastic lymphoma kinase (ALK),CD117,or CD34.Fluorescence in situ hybridization (FISH) revealed the presence of a fusion gene (t(11:14) CCND1/IGH) in the abnormal lymphocytes.Based on the above findings,the diagnosis was made as blastoid mantle cell lymphoma with skin and periorbital involvement complicated by hypercalcemia.After treatment with rituximab injection,cyclophosphamide,vincristine,doxorubicin,dexamethasone,and intermittent treatment with intravenous high dose of methotrexate and cytarabine (R-Hyper-CVAD),serum calcium returned to a normal level three days later,and the patient made a quick and excellent recovery on the 6th day,with the regression of skin lesions and poriorbital swelling.Unfortunately,the patient eventually died of severe pulmonary infection one month later.

Objective To summarize the experience in diagnosis and treatment of primary splenic neoplasm (PSN) to promote understanding of the disease. Methods The clinical data of all admitted patients with PSN treated in this hospital from February 1989 to February 2004 were retrospectively analyzed. Results A total of 63 patients were treated by surgery and pathologically confirmed as PSN. Twenty-one patients were treated by splenectomy alone. Twenty-seven patients underwent distal pancreatectomy and splenectomy. Fifteen patients received splenectomy combined with excision of tumor, the 5-year survival rate was 35.9%(15/42). Conclusion PSN should be diagnosed mainly according to clinical manifestations, image examination, and fine needle aspiration biopsy. CT and angiography play an important role in the identification of benign and malignant splenic mass. Early diagnosis, radical resection and comprehensive treatment are important for improving the prognosis of PSN.

Objective: The study was to reveal the inhibition of neovascularization by Tongbiling. Methods: Rat model were established by injecting CFA at the root of the tail and divided into model control group, Indomethacin group and Tongbiling group at random. The serum and paws were collected after seven days treatment. 10ng/L VEGF solution was added I into CAM to stimulate the neovascularization, and to observe the influence of each group of serum on the first and second order new vessels. RT-PCR method was taken to determine the expression of mRNA of VEGF and VEGFR-1 of paws in different groups. Results: The number of vessels in the model control group was significantly more than that in the Indomethacin group and the Tongbiling group (P
10. Herpes simplex virus type induces β-amyloid expression in human neuroblastoma cell lines sh-sy5y
Academic Journal of Second Military Medical University 2018;39(10):1109-1114
Objective To explore the effect of herpes simplex virus type (HSV-1) infection on expression of β-amyloid (Aβ) in human neuroblastoma cell lines SH-SY5Y. Methods African green monkey kidney cell lines Vero cells were used to amplified HSV-1, and the virus titers were measured. SH-SY5Y cells were infected with HSV-1 3.2×108 plaque forming unit (PFU)/mL at a multiplicity of infection (MOI) of 10 for 12 h or 24 h, and the morphological changes of the cells were observed under microscope. PCR was used to detect the expression of HSV-1 DNA. Double-color immunofluorescence assay was performed to show the expression of Aβ and apolipoprotein E (ApoE). Western blotting was used to detect the expression levels of amyloid precursor protein (APP), melanin metabolic enzyme (MME), ApoE, glycogen synthase kinase-3β (GSK-3β) and phosphorylated glycogen synthase kinase-3β (p-GSK-3β). Results After infection with HSV-1 for 12 h, the SH-SY5Y cells had synapse reduction and neurite retraction and few neurites. And after 24 h of infection, the cells began to aggregate, and were round and shed. Compared with phosphate buffer saline (PBS) control group, the expression of Aβ was significantly increased after infection with HSV-1 for 12 h (P0.01), while the expression of ApoE protein was not significantly changed. After 24 h of infection, the expressions of Aβ and ApoE were significantly increased (P0.05), but the expression of Aβ was significantly lower than that on 12 h of post-infection (P0.01). Western blotting analysis showed that, compared with PBS control group, the expression of APP was significantly decreased on 12 h of post-infection (P0.05), and the expressions of GSK-3β, p-GSK-3β and MME were significantly increased (P0.05). However, the expression of MME was significantly decreased (P0.05) and the expression of ApoE was significantly increased (P0.05) 24 h post-infection. Conclusion HSV-1 infection induces the expression of Aβ in SH-SY5Y cells through promoting APP metabolism and Ser9 phosphorylation of GSK-3β on 12 h of post-infection, and inhibiting the degradation of Aβ on 24 h of post-infection.
