Objective To investigate the response of multiple myeloma (MM) cells to 8-chloroadenosine 3',5'-monophosphate (8-Cl-cAMP) and the impact of arsenic trioxide (As2O3) on the above reaction.Methods MM-derived cell lines RPMI8226 and U266 were used as in vitro models.Cell apoptosis was evaluated according to cellular morphology and DNA content measured by flow cytometry.Meanwhile,rhodamine 123 (Rh123) staining and flow cytometry assay were used to detect the changes of mitochondrial transmembrane potentials (△ψm) in MM cells before and after the treatment.The synergic effects of 8-Cl-cAMP and As2O3 were evaluated by King' s formula.Results The 8-Cl-cAMP could induce growth inhibition of RPMI8226 and U266 cells in dose and time-related manners.The 8-Cl-cAMP could trigger apoptosis and △ψm collapse in MM cells through cellular morphology and flow cytometry analysis.As2O3 accelerated 8-Cl-cAMP-mediated apoptosis of RPMI8226 cells,but there were few synergic effects observed.Conclusion 8-Cl-cAMP could induce cell proliferation inhibition and apoptosis in MM cells.Mitochondria may be one of targets in 8-Cl-cAMP-mediated apoptosis.Furthermore,As2O3 catalyzes 8-Cl-cAMP-induced apoptosis.

Objective:To explore the clinical effect of Pingchuan Decoction combined with routine western medicine therapy in the treatment of acute attack of bronchial asthma in children. Methods:From January 2017 to June 2019, 118 children with acute attack of bronchial asthma were selected from the Seventh People’s Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and they were randomly divided into control group (59 cases) and observation group (59 cases) according to the random number table. The control group was treated with routine western medicine therapy, and the observation group was treated with Pingchuan Decoction on the base of control group, and both groups were treated for 14 days. The main symptom scores before and after treatment were evaluated. The percentage of forced vital capacity expressed as percent predicted (FVC% pred) and the forced expiratory volume in 1 second expressed as percent predicted (FEV1% pred) were measured by pulmonary function meter. The levels of CD3 +, CD4 + and CD4 +/CD8 + in peripheral blood were detected by flow cytometry. The adverse reactions during the treatment were recorded and the clinical efficacy was evaluated. Results:The total clinical effective rate was 93.2% (55/59) in the observation group and 71.2% (42/59) in the control group, where the difference between the two groups was statistically significant ( χ2=9.790, P=0.002). After treatment, the scores of cough, wheezing and wheezing rale in the observation group were significantly lower than those in the control group ( t=27.695, 17.573, 32.827, P<0.001). After treatment, FVC% pred [(80.21 ± 4.06)% vs. (71.71 ± 3.95)%, t=11.526], FEV1% pred [(78.84±3.92)% vs. (72.26 ± 3.59)%, t=9.508] in the observation group were significantly higher than those in the control group ( P<0.01). The levels of CD3 + [(74.05 ± 5.13)% vs. (67.44 ± 4.98)%, t=7.101], CD4 + [(48.43 ± 4.31)% vs. (42.20 ± 4.06)%, t=8.082] and the ratio of CD4 +/CD8 + (1.67 ± 0.29 vs. 1.34 ± 0.25, t=6.620) in the observation group were significantly higher than those in the control group ( P<0.01). During the treatment, the incidence of adverse reactions was 10.2% (6/59) in the observation group and 6.8% (4/59) in the control group, and there was no significant difference between the two groups ( χ2=0.437, P=0.509). Conclusion:The Pingchuan Decoction combined with routine western medicine therapy can reduce the clinical symptoms of children with acute attack of bronchial asthma, improve lung function, improve organism immunity and clinical effect with safety.

Objective To evaluate the diagnostic value of high frequency ultrasound in sebaceous gland carcinoma of eyelid (SC).Methods The ultrasonic characteristic for 11 cases with eyelid SC were respectively analyzed by using 13 MHz high frequency ultrasound and 22 MHz ultra-high frequency ultrasound.Results Through 13 MHz high frequency ultrasound,in 7 patients who exhibited Pagetoid invasion the lid shin thickness of tumor side displays no significant alteration in a comparison with normal side.Furthermore,the color Doppler flow imaging (CDFI) evealed a branch-like blood flow surrounding the masses in all cases,but the blood flow of seven patients with Pagetoid invasion had no difference compared with the healthy side.On 22 MHz ultra-high frequency ultrasound examination,slit-like low echo was found in 9 ;transition zone of tumor infiltration can be identified in 9 ; the echo of tumors with Pagetoid invasion was lower than the healthy side and the skin thickness of tumors with Pagetoid invasion was thicker (0.6 ±0.1) mm than the healthy side.CDFI revealed that mesh-basket like blood flow was rich in all patients,the small branch blood vessels arrived at subcutaneous,and vasa vasorum were found in some patients.The region with Pagetoid invasion was rich in blood flow.The sonography findings on 13 MHz and 22 MHz high frequency ultrasound examination were compared with chisquare test.There were significant differences on homogeneous echo,slit-like low echo,transition zone of tumor infiltration,infiltration skin thickness,blood distribution,central blood vessels,vasa vasorum,blood flow in the region with Pagetoid invasion (x2 =12.571,15.231,15.231,4.701,22.000,15.231,4.899,10.267,P＜0.05).Conclusions Slit-like low echo in the mass is a main finding of eyelid sebaceous gland cercinoma on the 22 MHz ultra-high frequency ultrasound.The ultra-high frequency ultrasound can accurately reveal the skin depth infiltrated by the eyelid sebaceous gland cercinoma and this method can provide solid guidance for clinical treatment strategies.

Objective To characterize contemporary electrographic neonatal seizures by video electroencephalogram (VEEG) and to assess the value and the limitations of two-channel (C3-C4/T3-T4) amplitude-integrated electroencephalogram (aEEG) plus original EEG signals used to diagnose neonatal seizure with video EEG as a golden standard.Methods Sixty-six neonates admitted to Children's Hospital of Fudan University from January 2011 to July 2011 with clinical or suspected clinical seizure were investigated and bedside VEEG were recorded for more than 3 hours.VEEG signals were transformed into three kinds of aEEG signals by Galileo NT PMS software:one-channel aEEG (C3-C4),one-channel aEEG (C3-C4) plus original EEG,two-channel aEEG (C3-C4/T3-T4) plus original EEG.Electrical seizure activity on VEEG was signed out with respect to its occurrence,duration and localization of seizure onset; while aEEG seizure was recorded only with its occurrence.The relationship between aEEG and VEEG was analyzed by Spearman analysis.The value and the limitations of aEEG to diagnose neonatal seizure were evaluated by sensitivity,specificity,positive predictive value and negative predictive value.Results A total of 62 traces were suitable for analysis.(1) VEEG showed 39 seizure activities,among which 8 status epilepticus; and the rest 31 neonates had 352 non-status epilepticus electrical seizures,79.3％ (279/352) of which occurred over the centrotemporal region.(2) Eight cases with status epilepticus on VEEG were all diagnosed as status epilepticus on aEEG.For non-status epilepticus electrical seizures,the sensitivity of aEEG for detection of electrical seizures was as followed:49.1％ (173/352) for one-channel aEEG,54.5 ％ (192/352) for one-channel aEEG plus original EEG,81.2％ (286/353) for two-channel aEEG plus original EEG.Results from one-channel aEEG,one-channel aEEG plus original EEG and two-channel aEEG plus original EEG were all related to VEEG (ρ =0.790,0.907 and 0.953,respectively,P＜ 0.01).(3) Sensitivity of seizure detection was 66.7％ (26/39,95％ CI:0.62-0.81) for one-channel aEEG,74.4％(29/39,95％ CI:0.78-0.96) for one-channel aEEG(C3-C4) plus original EEG and 89.7％ (35/39,95％ CI:0.89-1.00) for two-channel aEEG(C3-C4/T3-T4) plus original EEG.Conclusions VEEG might help aEEG in diagnosis of neonatal seizure.two-channel aEEG (C3-C4/T3-T4) plus original EEG could significantly increase the sensitivity of neonatal seizures indentification.

A total of 20 normal newborns and 8 brain injured newborns were monitored for 2 hours with domestic digital amplitude integrated cerebral function monitor (CFM 3000) and similar imported products LECTROMED CFM 5330 simultaneously. 32 newborns with seizures or suspected seizures were monitored with CFM 3000 and conventional electroencephalogram (EEG) simultaneously. The tracings of amplitude integrated electroencephalogram (aEEG) monitored by CFM 3000 and LECTROMED CFM 5330 are similar to each other. The continuous electrical activity, sleep-wake cycle, the mean of lower or upper bound voltage and duration of broad and narrow band were no significant statistical difference between different machines; The pattern of aEEG tracing of 8 infants with brain injury monitored by CFM 3000 was the same as monitored by the LECTROMED CFM 5330. The detection rate of seizure with CFM 3000 and conventional EEG were no statistically significant difference, and the consistency with Kappa test was: Kappa = 0.552, P = 0.001. The CFM 3000 can reflect the change of cerebral function and identify infants with brain injury reliably.

Background The benchmark dose (BMD) method calculates the dose associated with a specific change in response based on a specific dose-response relationship. Compared with the traditional no observed adverse effect level (NOAEL) method, the BMD method has many advantages, and the 95% lower confidence limit of benchmark dose lower limit (BMDL) is recommended to replace NOAEL in deriving biological exposure limits. No authority has yet published any health-based guideline for rare earth elements. Objective To evaluate genotoxicity threshold induced by acute exposure to neodymium nitrate in mice using BMD modeling through micronucleus test and comet assay. Methods SPF grade mice (n=90) were randomly divided into nine groups, including seven neodymium nitrate exposure groups, one control group (distilled water), and one positive control group (200 mg·kg⁻¹ ethyl methanesulfonate), 10 mice in each group, half male and half female. The seven dose groups were fed by gavage with different concentrations of neodymium nitrate solution (male: 14, 27, 39, 55, 77, 109, and 219 mg·kg⁻¹; female: 24, 49, 69, 97, 138, 195, and 389 mg·kg⁻¹) twice at an interval of 21 h. Three hours after the last exposure, the animals were neutralized by cervical dislocation. The bone marrow of mice femur was taken to calculate the micronucleus rate of bone marrow cells, and the liver and stomach were taken for comet test. Results The best fitting models for the increase of polychromatophil micronucleus rate in bone marrow of female and male mice induced by neodymium nitrate were the exponential 4 model and the hill model, respectively. The BMD and the BMDL of female mice were calculated to be 31.37 mg·kg⁻¹ and 21.90 mg·kg⁻¹, and those of male mice were calculated to be 58.62 mg·kg⁻¹ and 54.31 mg·kg⁻¹, respectively. The best fitting models for DNA damage induced by neodymium nitrate in female and male mouse hepatocytes were the exponential 5 model and the exponential 4 model, respectively, and the calculated BMD and BMDL were 27.15 mg·kg⁻¹ and 11.99 mg·kg⁻¹ for female mice, and 16.28 mg·kg⁻¹ and 10.47 mg·kg⁻¹ for male mice, respectively. The hill model was the best fitting model for DNA damage of gastric adenocytes in both female and male mice, and the calculated BMD and BMDL were 36.73 mg·kg⁻¹ and 19.92 mg·kg⁻¹ for female mice, and 24.74 mg·kg⁻¹ and 14.08 mg·kg⁻¹ for male mice, respectively. Conclusion Taken the micronucleus rate of bone marrow cells, DNA damage of liver cells and gastric gland cells as the end points of genotoxicity, the BMDL of neodymium nitrate is 10.47 mg·kg⁻¹, which can be used as the threshold of genotoxic effects induced by acute exposure to neodymium nitrate in mice.
