Objective To investigate the immunological characteristics and clinical significance of reactive plasmacytosis in patients with severe fever with throbocytopenia syndrome (SFTS).Methods Bunyavirus-infected patients who were diagnosed with SFTS were collected from March 2015 to October 2015 in Taizhou Hospital.Morphology analysis of bone marrow and peripheral blood (PB) smear, as well as flow cytometry analysis of plasma cell immune phenotype from peripheral blood were conducted.Serum immunoglobulin levels and helper T hymphocytes (Th)1/Th2 cytokine expressions were detected.Mann-Whitney U test was used.Results PB plasma cells from all of the SFTS patients increased in varying degrees, and the phenotype of the plasma cells was CD19+CD38++CD45+CD138+, which indicated normal mature plasma cells.The ratio of PB plasma cells was >0.030 in 10/16 patients, and >0.300 in 2/16 patients.The ratios of PB plasma cells in the patients with severe and critical groups were significantly higher than that in the mild group (0.052 vs 0.016, P<0.05).Monocytoid histiocytes and hemophagocytes were observed in the BM morphology of 9 patients.Three of them were diagnosed as hemophagocytic lymphohistiocytosis (HLH).The ratio of plasma cells was more than 0.030 in the bone marrow of 8 patients.The serum levels of interlewkin (IL)-6, IL-10 and interferon (IFN)-γ in acute phase were significantly elevated with the median level of 49.75 ng/L, 26.98 ng/L (reference value 2.6 to 4.9 ng/L) and 17.57 ng/L, respectively.While the levels of IL-2, IL-4 and twmor necrosis fautor(TNF)-α were not significantly changed.The serum IL-6 and IL-10 levels in the patients with severe and critical groups were both significantly higher than those in the mild group (IL-6: 132.36 vs 22.81 ng/L;IL-10: 75.28 vs 6.33 ng/L, both P<0.05), but the difference of IFN-γ level was not significant (P>0.05).The serum IgG, IgA and IgM levels did not increase in acute stage, with the median of 11.6 g/L, 2.56 g/L and 1.60 g/L (reference value 0.46 to 3.04 g/L), respectively.Conclusion The patients with SFTS show excessive humoral and cellular immunity, and the severity of disease is positively correlated with the ratio of peripheral plasma cells and the levels of cytokines IL-6 and IL-10.

BACKGROUND: As unspecific antagonist of opiate receptor, naloxone is widely used for multiple diseases which are related with abnormal release of endogenous opium. At present, researches suggest that large dosage of naloxone is used at early period can decrease death rate of patients with acute craniocerebral injury and promote neural functional recovery.OBJECTIVE: To investigate the effect of naloxone on improving the nervous function of rats with acute craniocerebral injury and to analyze effectively.DESIGN: Randomized grouping design based on the experimental animal.SETTING: Beijing Neurosurgical Institute.MATERIALS: Totally 250 SD rats were divided randomly into 0.3, 1.0,3.0, 9.0 mg/kg naloxone group, positive control group and negative control group.METHODS: Craniocerebral injured model was established with Feenly free fall struck, and the medicine was given 30 minutes after injury. The rats of the first four experimental group were injected transpeniponeally with naloxone hydrochloride by 0.3 mg/kg, 1.0 mg/kg, 3.0 mg/kg and 9.0 mg/kg respectively once a day; meanwhile, the control groups were given 2 mg citicoline sodium for injection and 0.5 mL normal saline per rat respectively. The longest time was 14 days.MAIN OUTCOME MEASURES: MNSS neural functional score was used every day. The brain edemas of 8 rats in each group were measured with wet-dry weight methods on the second and the fourth day after head trauma.RESULTS: Among 250 rats, 172 entered the final analysis. The nervous function of rats in naloxone groups was better than the two control groups (P ＜ 0.01), and that in 1, 3 and 9 mg/kg naloxone group were better than 0.3 mg/kg group (P ＜ 0.05), but there were no significant differences a mong the three naloxone groups (P ＞ 0.05). The brain edemas of rats in naloxone groups were lighter than that in the control groups (P ＜ 0.05), and that of 1, 3 and 9 mg/kg groups were lighter than 0.3 mg/kg (P ＜ 0.05), but there were no significant differences among these three groups (P ＞ 0.05).CONCLUSION: Naloxone can decrease the brain edemas of rats with traumatic brain injury, promote the nervous function recovery, and the treatment effect changes with the dosage during some range.Therefore, the experiment illustrates that naloxone can decrease the brain edemas of experimental brain injury in SD rats and improve the nervous function, but the effect of naloxone is associated with the dosages in some range.

This study is to assess the efficacy of BPCBG on the decorporation of uranium (VI) and protecting human renal proximal tubular epithelial cells (HK-2) against uranium-induced damage. BPCBG at different doses was injected intramuscularly to male SD rats immediately after a single intraperitoneal injection of UO2(CH3COO)2. Twenty-four hours later uranium contents in urine, kidneys and femurs were measured by ICP-MS. After HK-2 cells were exposed to UO2(CH3COO)2 immediately or for 24 h followed by BPCBG treatment at different doses for another 24 or 48 h, the uranium contents in HK-2 cells were measured by ICP-MS, the cell survival was assayed by cell counting kit-8 assay, formation of micronuclei was determined by the cytokinesis-block (CB) micronucleus assay and the production of intracellular reactive oxygen species (ROS) was detected by 2',7'-dichlorofluorescin diacetate (DCFH-DA) oxidation. DTPA-CaNa3 was used as control. It was found that BPCBG at dosages of 60, 120, and 600 micromol kg(-1) resulted in 37%-61% increase in 24 h-urinary uranium excretion, and significantly decreased the amount of uranium retention in kidney and bone to 41%-31% and 86%-42% of uranium-treated group, respectively. After HK-2 cells that had been pre-treated with UO2(CH3COO)2 for 24 h were treated with the chelators for another 24 h, 55%-60% of the intracellular uranium was removed by 10-250 micromol L(-1) of BPCBG. Treatment of uranium-treated HK-2 cells with BPCBG significantly enhanced the cell survival, decreased the formation of micronuclei and inhibited the production of intracellular ROS. Although DTPA-CaNa3 markedly reduced the uranium retention in kidney of rats and HK-2 cells, its efficacy of uranium removal from body was significantly lower than that of BPCBG and it could not protect uranium-induced cell damage. It can be concluded that BPCBG effectively decorporated the uranium from UO2(CH3COO)2-treated rats and HK-2 cells, which was better than DTPA-CaNa3. It could also scavenge the uranium-induced intracellular ROS and protect against the uranium-induced cell damage. BPCBG is worth further investigation.
