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.

BACKGROUNDKeyhole surgery has developed since the 1990s as a less invasive therapeutic strategy for intracranial lesions, initially for the treatment of intracranial aneurysms. The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions.

METHODSBetween April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach.

RESULTSNo significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery.

CONCLUSIONThe supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.

OBJECTIVE: To examine the normal range of the width of posterior cranial fossa (WPCF) in the second and third trimester by ultrasonography, and to investigate its relationship with fetal congenital and chromosome abnormality. METHODS: WPCF of 2484 fetus (gestational age from 14 to 41 weeks) was measured by ultrasonograph routinely, and the infants were followed up. RESULTS: In 2848 fetus, 2772 were normal and 76 were abnormal. WPCF increased before 32 weeks, decreased after 33 weeks, the largest value of WPCF was 13.4 mm. The occurrence rate of WPCF> or =8 mm in normal fetus was 8.84%, and that in abnormal fetus was 17.46%. Most fetuses with chromosome abnormality had normal WPCF in the second trimester, but some fetuses with remarkable broadening in the late stage. Some abnormal fetuses (such as water head, Dandy-Walker's syndrome etc) showed significant extension of WPCF. CONCLUSION WPCF increases before 32 weeks, decreases after 33 weeks;and can be easily measured during 29 - 32 weeks. WPCF of some fetus with chromosome abnormality or with congenital abnormality is remarkably broadened in the late stage. The fetus of WPCF> or =10 mm should be followed up closely, and antenatal diagnosis should be done if WPCF is more than 14 mm.

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.
