Objective:To analyze the clinical manifestations and laboratory features of brucellosis patients in order to provide help for clinical diagnosis.Methods:The medical records of confirmed brucellosis patients ( n=81) in Kunming Third People's Hospital from 2015 to 2019 were collected. The occupation, contact history, clinical manifestations, laboratory examination characteristics and treatment of the patients were retrospectively analyzed. Results:The 81 cases of brucellosis were mainly farmers (64 cases), most of who had a history of raising sheep or contacting sheep manure or secretions (71 cases). The clinical manifestations were fever (68 cases), low back pain (42 cases), joint pain (22 cases), including 72 cases in acute stage and 9 cases in chronic stage. Laboratory examination showed that liver function index total bilirubin (TB) and direct bilirubin (DB) were generally normal, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyltransferase (GGT) were increased in about half of the patients; high sensitivity C-reactive protein (HsCRP), procalcitonin (PCT), interleukin-6 (IL-6) and serum amyloid A (SAA) were increased in more than 80% of the patients, and erythrocyte sedimentation rate (ESR) was increased in 64.6% (42/65) of the patients. Doxycycline plus rifampicin was the first-line treatment program.Conclusion:The clinical manifestations of patients with brucellosis are diverse and atypical, and patients with nonspecific clinical manifestations such as fever should be combined with their occupation, contact history, indicators of infection detection, timely blood culture examination to make a clear diagnosis, and patients with abnormal liver function should pay attention to asking about occupation and contact history, so as to reduce misdiagnosis and mistreatment of brucellosis.

This paper aims to investigate if the dental restoration of nickel-chromium based alloy (Ni-Cr) leads to the enhanced excretions of Ni and Cr in urine. Seven hundred and ninety-five patients in a dental hospital had single or multiple Ni-Cr alloy restoration recently and 198 controls were recruited to collect information on dental restoration by questionnaire and clinical examination. Urinary concentrations of Ni and Cr from each subject were measure by graphite furnace atomic absorption spectrometry. Compared to the control group, the urinary level of Ni was significantly higher in the patient group of <1 month of the restoration duration, among which higher Ni excretions were found in those with either a higher number of teeth replaced by dental alloys or a higher index of metal crown not covered with the porcelain. Urinary levels of Cr were significantly higher in the three patient groups of <1, 1 to <3 and 3 to <6 months, especially in those with a higher metal crown exposure index. Linear curve estimations showed better relationships between urinary Ni and Cr in patients within 6-month groups. Our data suggested significant increased excretions of urinary Ni and Cr after dental restoration. Potential short- and long-term effects of Ni-Cr alloy restoration need to be investigated.

Objective The relationship between firing pattern and sensitivity of neurons was studied in chronically compressed dorsal root ganglion (DRG) neurons and the Hindmarsh-Rose (HR) neuronal model. Methods Spontaneous activities from single fibers of chronically compressed DRG neurons in rats were recorded, and divided into periodic and non-periodic firing patterns. The sensitivity of the two kinds of firing pattern neuron to sympathetic stimulation (SS) was compared. Result It was found that 27.3% of periodic firing neurons and 93.2% of non-periodic firing neurons responded to SS respectively (periodic vs non-periodic, P < 0.01). The responses to SS with different stimulation time were greater non-periodic firing neurons than periodic firing neurons (P < 0.01). The non-periodic firing neurons obviously responded to SS. After the firing pattern of these neurons transformed to periodic firing pattern, their responses to SS disappeared or decreased obviously. The HR neuronal model exhibited a significantly greater response to perturbation in non-periodic (chaotic) firing pattern than in periodic firing pattern. Conclusion The non-periodic firing neurons with deterministic chaos are more sensitive to external stimuli than the periodic firing neurons.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.
