Presence of Spontaneous Nystagmus, Benign Paroxysmal Positional Vertigo, and Tumarkin Fall in Patients With Primary Headache and Their Responses to Caloric and Video Head Impulse Tests.

Background: Migraine, vestibular migraine (VM) and tension-type headache (TTH) are the most common disorders in dizziness and headache clinics, associated with dizziness or vertigo and postural imbalance, causing a substantial burden on the individual and the society. The objective of this research was to examine the presence of spontaneous nystagmus, comorbidity of benign paroxysmal positional vertigo (BPPV), and Tumarkin fall in patients; additionally, the study focused on assessing the patients' responses to bithermal caloric irrigation and video head impulse test (vHIT).

Methods: Consecutive patients diagnosed with migraine, VM, and TTH according to the International Classification of Headache Disorders, third edition (beta version (ICHD-3β)), who were referred to Dizziness and Headache Clinic were enrolled.

[Inhibitory Effect of PKC412 Against Human Acute Leukemia Cell Line HL-60 Cells].

Objective: To explore the effects and mechanisms of PKC412 inhibitor on proliferation and apoptosis of HL-60 cell line.

Methods: CCK-8 assay was used to detect the effect of PKC412 on the proliferation of HL-60 cells at different concentrations; Wright-Giemsa staining was used to estimated the effect of PKC412 on the apoptosis of HL-60 cells; the mRNA expression of BCL-2 and P53 genes was detected by qRT-PCR, the expression of BCL-2 and P53 proteins was detected by Western blot. HL-60 cells were injected into mouse caudal vein to construct acute myeloid leukemia model, PKC412 was administered to tail vein for 31.

Could cytokine release syndrome induce acute myelofibrosis in CD19 chimeric antigen receptor T cells therapy?

CAR-T cells therapy can give rise to most common and concerning two side effects - cytokine release syndrome (CRS) and neurotoxicity. But in our CD19 CAR-T cells therapy clinical trial, we observed 1 out of 17 patients with B-cell acute lymphoblastic leukemia (B-ALL) developed acute myelofibrosis(AMF) after grade IV CRS post to the CD19 CAR-T cells therapy. This finding suggests that the CAR-T cells therapy may have rare and serious AMF, which we should pay important attention to.

[Impact of JAK2V617F Mutation Burden on Clinial Presentation and Survival in ET Patients].

Objective: To better define the effect of JAK2V617F mutant allele burden on clinical presentation of patients with essential thrombo cythamia (ET), especially thrombosis.

Methods: Two ml of heparin anti-coagulated bone marrow was collected from 229 ET cases, who were diagnosed and treated in the First People's Hospital of Yunnan Province during 2013.10 to 2016.

[In vitro heart models simulating in vivo cardiac ischemia-reperfusion injury].

The aim of this study was to compare in vivo and several in vitro cardiac ischemia-reperfusion (I-R) myocardial injury models, and choose a superior in vitro cardiac I-R model. Sprague-Dawley (SD) rats were randomly grouped into in vivo, Langendorff, Langendorff + pacing, and working heart groups. Left anterior descending (LAD) coronary artery was ligated for 60 min and then reperfused for 120 min in in vivo and in vitro rat hearts.

Dys-psychological Stress Effect on Expressions of P53 and NFκBp65 in Human Ovarian Carcinoma In Vivo.

Objective: To investigate the dys-psychological stress effect on the growth of subcutaneous xenotransplanted tumor in nude mice bearing human epithelium ovarian carcinoma, and the influence on P53 and NFκBp65 expressions.

Methods: The subcutaneous tumor xenografts were established by implanting human epithelium ovarian carcinoma tissues into nude mice and the dys-psychological stress model was established with restraint. The mice were randomized into the following four treatment groups with each group six mice respectively: tumor group (group A), normal saline intraperitoneal injection; tumor with stress group (group B), normal saline intraperitoneal injection; tumor therapy group (group C), cisplatin intraperitoneal injection; and tumor therapy with stress group (group D), cisplatin intraperitoneal injection.

[Association between XRCC1 gene polymorphisms and DNA damage of workers exposed to formaldehyde].

Objective: To investigate the association between polymorphisms of DNA repair gene XRCC1 and DNA damage in peripheral blood lymphocytes among workers exposed to formaldehyde.

Methods: One hundred and fifty-one workers exposed to formaldehyde from plywood factories and one hundred and twelve workers without occupational exposure to formaldehyde were recruited into this study. DNA damage levels were measured by comet assay.

[Early genetic effects on workers occupationally exposed to formaldehyde].

Objective: To investigate the DNA and chromosome damage in peripheral blood lymphocyte of workers occupationally exposed to formaldehyde (FA).

Methods: All 151 workers occupationally exposed to FA from two plywood factories and 112 workers without occupational FA exposure working in a machine manufactory were recruited into this study. Comet assay and cytokinesis-block micronucleus technique was used to evaluate the DNA and chromosomal damage of peripheral blood lymphocyte.

[Exploration on the relationship between positive antisperm antibody and nitric oxide level of infertile patients and on integrative Chinese and Western medicine treatment].

Objective: To study the relationship between the positive antisperm antibody (AsAb) and nitric oxide (NO) content in blood of infertile patients and the therapeutic effect of integrative Chinese and western medicine (ICWM) treatment on the disease.

Methods: Infertile patients, 75 of AsAb positive and 68 of AsAb negative were selected to observe the mature partuient rate and abortion rate. Serum NO level were measured before treatment to observe the relationship between NO and positive AsAb.
