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.

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

Objective To study the effect of teaching methods of question type and discussion type that are adopted during the clinical probation of hematology. Methods 200 students of 5-year system of clinical medical of zhongshan medical college of Sun Yat-sen University were sclected to use the teaching methods of question type and discussion type during the clinical probation of hematology. Results It displayed that the probation teaching methods of question type and discussion type received good evaluation from the students, and obtained good probation effect. Conclusions The problem-based teaching methods evoked and guided the students proceeding transversal and lenth clinical wise; The case discussion elevatered the students’ ability to resovle practical problems with theoretical knowledge.

ObjectiveTo investigate suicidal ideation and its risk factors in patients with borderline personality disorder (BPD),and raise awareness of suicidal risk in BPD.MethodsPatients with BPD were selected from in-patient and out-patient departments as case group(n=84),while 84 subjects were selected as control group,1∶1 matched by gender and age.Barratt impulsiveness scale,Buss-Perry aggression questionnaire,childhood trauma questionnaire,Beck depression inventory,Beck hopelessness scale and Beck scale for suicide ideation were used to measure the two groups.Results(1)In case group,the number of incidence of suicidal occurred was 84.The scores of suicidal ideation in the recent week(4.94±4.57 vs 0.50±0.51),suicidal ideation in the worst situation(20.43±6.58 vs 1.26±2.60) and the total score(25.37±9.78 vs 1.76±3.65) were statistically higher than those in control group (t=8.499,24.972,20.847,all P<0.01).(2) Multiple regression analysis showed that motor impulsivity,physical neglect in childhood,impulsivity,co-morbidity of axis I disorders,physical abuse in childhood,unemployment and unmarried status were risk factors of suicidal ideation in patients with BPD (β=0.876,0.640,0.428,0.350,0.236,0.165,-0.205,all P<0.05).ConclusionThe suicide ideation of patients with BPD are prevalent and intense.Awareness of risk factors for patients with BPD,thereby reducing the risk of suicide.

Objective To explore the expression of DC?SIGN, the phenotype of dendritic cells (DCs), on podocytes, and its role in immune and inflammatory responses of lupus nephritis (LN). Methods DC?SIGN and IgG1 expression in renal tissues of lupus nephritis patients were observed by immunohistochemistry and immunofluorescence. The 4?week old LN mice were randomly divided into the experimental group and the intervention group. C57BL/6J mice were used as normal control group. Mice of the intervention group were injected anti?DC?SIGN antibody at 6?week old. Mice were sacrificed at 16, 20, 24, 28?week old respectively, to observe the mice renal function and pathological changes. And DC?SIGN and IgG1 expression in renal tissue were observed by immunohistochemistry and immunofluorescence. In addition, mice podocytes were treated with serum of LN mice. Flow cytometry was used to investigate the expression of MHC II, CD80 and DC?SIGN expression on podocytes. Mixed lymphocyte reaction was used to detect the ability of stimulating T cells proliferation. IFN?gamma and IL?4 in supernatant were determined by ELISA. Results (1) Expression of DC?SIGN and IgG1 was found in glomeruli of lupus nephritis patients. (2) Accompanied by increased proteinuria of LN mice from 20?week old (P<0.01), DC?SIGN and IgG1 expression was found in glomeruli, and the renal function deteriorated up to 24 week?old (P<0.01). Mice with anti?DC?SIGN antibody intervention appeared reduced proteinuria and remission of renal function (P<0.01). (3) After stimulated by serum of LN mice, the expression of DC?SIGN, MHC II and CD80 was up?regulated, stimulation of T cell proliferation was enhanced (P<0.01), and IFN?gamma/IL?4 ratio increased (P<0.01). Anti?DC?SIGN antibody treatment down?regulated the expressions of DC?SIGN, MHC II and CD80 on podocytes, decreased the ability of stimulating T cell proliferation and lowered the ratio of IFN?gamma/IL?4 (P<0.01). Conclusions Podocytes in lupus nephritis can play DC?like function through the expression of DC?SIGN, which may be involved in immune and inflammatory responses of renal tissue. However, inhibiton of DC?SIGN can depress immune function of podocytes and have prevention and treatment effect.

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.
