Allyl isothiocyanate (AITC) is a natural product commonly used in food preservation and pharmaceutical applications. Toxoplasmosis, caused by the protozoan pathogen Toxoplasma gondii, is prevalent globally while the impact of AITC on toxoplasmosis is unclear. We explored the effect of AITC on acute toxoplasmosis. We infected C57BL/6 mice with T. gondii type I RH strain following AITC administration. On the 4th day after infection, which corresponds to the initial stage of infection, we collected serum for the determination of inflammatory cytokine levels. The mice serum of the AITC-administered group contained significantly lower levels of granulocyte colony-stimulating factor, interferon-gamma, interleukin (IL)-23 subunit p19, IL-4, IL-6, and monocyte chemoattractant protein-1. The lifespan of the mice in the AITC-administered group was significantly reduced. In vitro experiments showed that AITC promoted the proliferation of intracellular T. gondii accompanied by the inhibition of IL-4, IL-1β, and IL-6 production in RAW264.7 macrophages. Our results showed that AITC facilitated T. gondii infection in the early stage by inhibiting the production of several inflammatory cytokines.

OBJECTIVE: To summarize and compare the clinical baseline characteristics of patients with monoclonal gammopathy of undetermined significance (MGUS), primary light chain amyloidosis (pAL), multiple myeloma (MM), or MM with concurrent amyloidosis, especially the differences in cytogenetic abnormalities. METHODS: The clinical data of 15 cases of MGUS, 34 cases of pAL, 842 cases of MM and 23 cases of MM with concurrent amyloidosis were analyzed and compared retrospectively. RESULTS: Cytogenetic statistics showed that the incidence of t (11; 14) in the four groups (MGUS vs pAL vs MM vs MM with concurrent amyloidosis) was 0%, 33.3%, 16.4%, and 15.8%, respectively (P=0.037); that of 13q deletion was 20.0%, 14.7%, 45.8% and 56.5%, respectively (P<0.001); gain of 1q21 was 50.0%, 12.5%, 47.4% and 40.9%, respectively (P=0.001). Proportion of pAL patients with 0, 1 and≥2 cytogenetic abnormalities (including 13q deletion, 17p deletion, 1q21 amplification and IgH translocation) accounted for 41.9%, 41.9% and 16.1%, respectively; while the proportion of the same category in MM was 17.6%, 27.3%, and 55.2% respectively; this ratio of MM with concurrent amyloidosis was more similar to MM. Subgroup analysis showed that genetic abnormalities (including 13q deletion, 17p deletion and 1q21 amplification) were comparable within t (11; 14) negative and positive groups. Compared with positive cases, t(11; 14) negative patients with MM or MGUS were more likely to have 13q deletions and multiple genetic abnormalities. CONCLUSION Clinical characteristics of pAL, especially cytogenetic abnormalities, are significantly different from MM with concurrent amyloidosis. It suggests that although the onset characteristics are similar, actually the two diseases belong to different disease subtypes which should be carefully predicted and identified.

Objective:Cardiopulmonary resuscitation quality index (CQI) is based on pulse oximetry plethysmographic waveform (POP), which have been proved able to reflect the peripheral circulation state as good as the quality of chest compression during cardiopulmonary resuscitation (CPR). It has been confirmed that CQI is as good as the partial pressure of end-tidal carbon dioxide (P ETCO 2) in prognostic evaluation of CPR patients. The purpose of this study was to explore whether advanced airway establishment affects the prognostic value of CQI during CPR. Methods:This was a prospective descriptive study. 376 patients receiving CPR were divided into advanced airway group and non-advanced airway group according to whether advanced airway was established, each of which was divided into ROSC (return of spontaneous circulation) group and non-ROSC group according to whether they got ROSC. The changes of CQI and P ETCO 2 during CPR were collected, and the relation of these parameters and the prognosis of patients was analyzed. Results:In advanced airway group, both CQI [(63.3±20.7) vs (49.7±23.8)] and P ETCO 2 [(19.8 (11.4, 31.6) vs 8.8 (3.3, 15.8)] mmHg were statistically different between ROSC group and non-ROSC group ( P <0.05). The cut-off value for these two parameters were 60.4 and 16.3 mmHg respectively. There was no significant difference between the two curves ( P>0.05). In the non-advanced airway group, CQI [(63.0±21.8) vs (42.2±29.0)] were also statistically different between the ROSC group and the non-ROSC group ( P <0.05). The cut-off value of CQI in advanced airway group and non-advanced airway group were 60.4 and 61.1, respectively. And there was no statistical difference between the two curves ( P>0.05). Conclusions:During CPR, CQI can be used to evaluate the prognosis of patients, which is as good as that of P ETCO 2. Establishment of advanced airway does not affect the prognostic evaluation of CQI during CPR.

BACKGROUNDCoarctation of the aorta (CoA) with aortic arch hypoplasia (AAH) is a relatively common congenital heart disease in clinical practice. Nonetheless, the corrective surgical technique for infants and children is a clinical problem that remains controversial. In this study, we sought to evaluate the surgical effects of aortic arch (AA) reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch for infants and young children with CoA and AAH.

METHODSBetween January 2009 and December 2015, a total of 22 infants and young children with CoA and AAH who underwent coarctation resection and aortoplasty with autologous pulmonary artery patch were enrolled in this study. The median age of patients was 4.5 (Q1, Q3: 2.0, 14.0) months and the median body weight was 5.75 (Q1, Q3: 4.10, 9.38) kg. All patients were diagnosed with CoA and AAH, and concomitant cardiac anomalies were corrected in one stage. Perioperative and postoperative data were collected and analyzed using the paired sample t-test.

RESULTSNo perioperative deaths occurred. No residual obstruction was detected by echocardiography. The postoperative pressure difference across the repaired segment of CoA was 14.05 ± 4.26 mmHg (1 mmHg = 0.133 kPa), which was smaller than the preoperative pressure difference (48.30 ± 15.73 mmHg; t = -10.119, P < 0.001). The median follow-up time was 29.0 (Q1, Q3: 15.5, 57.3) months. There was no death during the follow-up period, and all patients experienced obvious clinical improvement. Only one child underwent subsequent aortic balloon angioplasty due to restenosis. Computed tomography angiography showed that the AA morphology was smooth, with no aortic aneurysm or angulation deformity.

CONCLUSIONAA reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch could effectively correct CoA with AAH, and the rate of reintervention for restenosis is low.
