To identify the active constituents in vitro and blood-absorbed ingredients in vivo from Yin Chen Hao decoction provides scientific evidence for probing its prevention and treatment mechanism on acute liver injury. An ultrahigh performance liquid chromatography quadrupole-time of flight-mass spectrometry (UPLC-QTOF/MS) method was applied for analysis of Yin Chen Hao decoction and the serum samples of mice with con-A induced acute liver injury after preventive oral administration for 14 days (the use of all laboratory animals in this study was approved by the Ethics Committee of the Naval Medical University, 19YF1459400). A total of 90 chemical constituents were identified from Yin Chen Hao decoction, mainly were flavonoids, terpenoids, tannins, quinones. 5 prototype compounds were identified in the serum, including chrysophanol, deoxyrhapontin-8-O-gallate, mussaenosidic acid, herniarin, emodin. The established UPLC-QTOF/MS method could efficiently and sensitively identify the constituents in vitro and blood-absorbed ingredients of Yin Chen Hao decoction, primarily clarify the material basis of its hepatoprotective effect, and provided a scientific basis for the quality marker selection and the pharmacodynamic material basis research on the decoction.

Quarantine insects are economically important pests that frequently invade new habitats.A rapid and accurate monitoring method to trace the geographical sources of invaders is required for their prevention,detection,and eradication.Current methods based on genetics are typically time-consuming.Here,we developed a novel tracing method based on insect gut microbiota.The source location of the insect gut microbiota can be used to rapidly determine the geographical origin of the insect.We analyzed 179 gut microbiota samples from 591 individuals of 22 quarantine insect species collected from 36 regions in China.The gut microbiota of these insects primarily included Actinobacteria,Bacteroidetes,Cyanobacteria,Firmicutes,Proteobacteria,and Tenericutes.The diversity of the insect gut microbiota was closely associated with geographical and environmental factors.Different insect species could be distinguished based on the composition of gut microbiota at the phylum level.Populations of individual insect species from different regions could be distin-guished based on the composition of gut microbiota at the phylum,class,and order levels.A method for determining the geographical origins of invasive insect species has been established;however,its practical application requires further investigations before implementation.

Background: Approximately 15–20% cases of systemic lupus erythematosus (SLE) are diagnosed in children. There have been a few studies reporting the epidemiological data of pediatric?onset SLE (cSLE) in China, neither comparing the differences between cSLE and adult?onset SLE (aSLE). The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group (CSTAR) database. Methods: We made a prospective study of 225 cSLE patients (aged <16 years) and 1759 patients aged 16–50 years based on CSTAR registry. We analyzed initial symptoms, clinical presentations, SLE disease activity, damages, and outcomes of cSLE, as well as compared with aSLE patients. Results: The mean age of cSLE patients was 12.16 ± 2.92 years, with 187 (83.1%) females. Fever (P < 0.001) as well as mucocutaneous (P < 0.001) and renal (P = 0.006) disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects (P < 0.001). The cSLE patients were found to present more frequently with malar rash (P = 0.001; odds ratio [OR], 0.624; 95% confidence interval [CI ], 0.470–0.829) but less frequently with arthritis (P < 0.001; OR, 2.013; 95% CI, 1.512–2.679) and serositis (P = 0.030; OR, 1.629; 95% CI, 1.053–2.520). There was no significant difference in SLE disease activity index scores between cSLE and aSLE groups (P = 0.478). Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients (hazard ratio 0.335 [0.170–0.658], P = 0.001). The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log?rank test (0.557, P = 0.455). Conclusions: cSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difference in 5? year survival between cSLE and aSLE groups.

OBJECTIVETo investigate the effects of Vaspin on lipopolysaccharide (LPS)-induced acute respiratory distress syndrome (ARDS) in mice and explore the possible mechanism.

METHODSForty male C57B/L6 mice were randomized equally into control group, LPS group, Vaspin group and wortmannin group with corresponding treatments. The pathological changes of the lung tissues were evaluated by HE staining, and the severity of pulmonary edema was measured according to the wet/dry ratio (W/D) of the lung tissue. The lung permeability was evaluated by detecting total protein concentrations in the bronchoalveolar lavage fluid (BALF) using bicinchoninic acid (BCA) assay. Myeloperoxidase (MPO) activity in the lung tissue was detected using a MPO assay kit, and the levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the lungs were measured using ELISA. Immunohistochemical staining was performed to detect the expression of vascular cell adhesion molecule-1 (VCAM-1) and Western blotting was used to detect the protein expressions of cleaved caspase-3 and p-Akt in the lung tissues.

RESULTSCompared with the control group, the mice in LPS group displayed typical ARDS pathological changes in the lungs with significantly increased W/D, total protein concentrations in BALF, lung MPO activity, levels of IL-1β and TNF-α, and pulmonary expressions of VCAM-1 and cleaved caspase-3 (P<0.05) but decreased expression of p-Akt (P<0.05). These changes induced by LPS were significantly alleviated by the administration of Vaspin (P<0.05). The protective effects of Vaspin against ARDS were obviously attenuated by the PI3K inhibitor wortmannin (P<0.05).

CONCLUSIONVaspin protects against LPS-induced ARDS in mice possibly by inhibiting inflammation and protecting vascular endothelium through upregulation of the PI3K/Akt signal pathway.

Based on the electric field shielding and insulation technology, the single electrode dielectric barrier discharge ion source ( DBDI ) has the characteristics of uniform discharging, stability, and high ionization energy, and thus can be used to detect various samples with a large range of polarity. However, the ionization energy is too high to reduce the background signal noise, and thus affects the detection effectiveness to low polarity and low boiling point samples. To enhance the detection effectiveness to these samples, a method of eliminating electrons of single electrode DBDI by using external metal electrodes was developed in this study. Then, the single electrode DBDI was improved by an external needle electrode and an external metal net, respectively. The mechanism of those external metal electrodes was discussed, and the experimental studies were carried out. The results showed that the external metal net technology had an advantage in improving signal to noise ratio ( SNR ) , and the enhancement of SNR for the detection of isoprocarb, perfluorooctanoic acid and SudanⅢwas about 5-6 times. Based on the technology, a method for determination of Sudan Ⅲ in chili powder was developed. The recoveries, RSD and LOD were 83. 7%-94. 6% , 5. 6%-9. 0% and 23 mg/kg, respectively. The external metal electrode technique has broadened the detection range of single electrode DBDI to the field of low polarity, low boiling point and complex samples.
