OBJECTIVE To investigate the mechanism of Shenling baizhu san （SLBZS） in ameliorating ulcerative colitis （UC）. METHODS Mice were randomly divided into normal group， model group， and low-， medium-， high-dose SLBZS groups （3， 6， 12 g/kg）， with 10 mice in each group. Except for the normal group， mice in other groups were given free access to 3% dextran sulfate sodium solution for 7 days to establish UC models. Simultaneously， mice in each group were intragastrically administered corresponding medicinal liquid or double-distilled water once a day for consecutive 7 days. After the last administration， the histopathological morphology of colon tissues was observed； the serum levels of inflammatory factors including tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β） and IL-18 were detected； the total bile acid contents in liver， gallbladder and colon tissues were determined； the expression level of NOD-like receptor family pyrin domain-containing protein 3 （NLRP3） in colon tissues was tested. The expression levels of flora metabolism-related proteins [G protein-coupled receptor 41（GPR41），GPR43，farnesoid X receptor （FXR）， G protein-coupled bile acid receptor 1 （TGR5）， flavin-containing monooxygenase 3 （FMO3）， cytochrome P450 family 27 subfamily A member 1 （CYP27A1）， CYP7A1] in liver or colon tissues， as well as the proteins related to Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB）/NLRP3 inflammatory axis [TLR4， NF-κB， phosphorylated NF-κB （p-NF-κB）， myeloid differentiation factor 88 （MyD88）， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， caspase-1] in colon tissues were measured. RESULTS Compared with the model group， the colon tissue injury and inflammatory cell infiltration were alleviated in medium- and high-dose SLBZS groups. The serum levels of TNF-α， IL-1β and IL-18， total bile acid contents in liver and colon tissues， as well as the protein expression levels of FMO3 and CYP7A1 in liver tissues， TLR4， p-NF-κB， NF-κB， MyD88， NLRP3， ASC and caspase-1 in colon tissues were significantly decreased （P＜0.05）. Meanwhile， the total bile acid content in gallbladder， the protein expression levels of GPR41 and GPR43 in colon tissues， along with CYP27A1， FXR and TGR5 in liver tissues were significantly increased （P＜0.05）. CONCLUSIONS SLBZS may relieve colonic inflammatory injury and ameliorate UC by regulating the expression of flora metabolism-related proteins and inhibiting the abnormal activation of TLR4/NF-κB/NLRP3 inflammatory axis.

ObjectiveTo investigate the effects of different fermentation methods and times on the fungal flora and chemical composition of Aurantii Fructus， in order to obtain the optimal fermentation conditions and flora structure， and to ensure the stability and controllability of the fermented varieties. MethodsScanning electron microscopy was used to observe and analyze the colony characteristics on the surface of Aurantii Fructus under different fermentation conditions. Internal transcribed spacer 2（ITS2） high-throughput sequencing， combined with fungal community diversity analysis and fungal community structure analysis， were used to obtain the fungal flora microbial categories of Aurantii Fructus under the conditions of traditional pressure-shelf fermentation and non-pressure-shelf natural fermentation for 7， 14， 21 d（numbered Y1-Y3 for the former， and numbered F1-F3 for the latter）， respectively. At the same time， the chemical components in the fermentation process were detected by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）， combined with principal component analysis（PCA）， partial least squares-discriminant analysis（PLS-DA） and compound retention time， parent ions， characteristic fragment ions and other information， the differential compounds between the different fermentation samples were screened and identified. ResultsThe analysis of fungal community diversity showed that the dominant flora did not change at different fermentation time points in the traditional pressure-shelf fermentation method， while in the non-pressure-shelf natural fermentation method， there was a significant difference with the fermentation process， and at the genus level， the dominant genus of samples Y1， Y2， Y3 and F2 was Aspergillus， while the dominant genera of samples F1 and F3 were both Rhizopus. This indicated that the microbial growth environment provided by the traditional fermentation method was more stable， and the microbial community structure was more stable， which was more conducive to the stable and controllable fermentation process and fermented products. A total of 155 compounds were identified by compositional analysis， including 70 flavonoids， 38 coumarins， 10 alkaloids， 34 organic acids and 3 other compounds. After fermentation， two new components of ribalinine and pranferin were produced. Different fermentation conditions also brought about differences in chemical composition， multivariate statistical analysis obtained 26 differential compounds under two different fermentation methods， mainly including flavonoids， organic acids and coumarins. Comprehensively， the microbial community structure of samples fermented by the traditional pressure-shelf method of Aurantii Fructus for 14 d was stable， the species richness was high and the overall content of differential compounds was high， which was the optimal processing condition. ConclusionCompared with non-pressure-shelf natural fermentation， the traditional method has obvious advantages in terms of the stability of the microbial community structure and the content of chemical compounds， and the optimal condition is 14 days of fermentation. This study is helpful to promote the quality stability and fermentation bioavailability of fermented products of Aurantii Fructus， as well as to provide an experimental basis for the further improvement of the quality control methods of this variety.

Objective To investigate the mineral contents of colostrum and peripheral blood and their correlation in pregnant women in Beijing. Methods A total of 80 pregnant women who gave birth in the Affiliated Fuxing Hospital of Beijing Capital Medical University in May 2019 were selected as research subjects, and their colostrum and peripheral blood samples were collected. The contents of 46 minerals in the colostrum and peripheral blood samples were determined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Atomic fluorescence spectrum (AFS). The correlation between the contents of minerals in the colostrum and peripheral blood was analyzed by SPSS 21.0. Results Among the 46 minerals detected, the minerals with higher contents in the peripheral blood were sodium, potassium, iron, magnesium, calcium, zinc, rubidium, copper, aluminum and selenium. The minerals with higher colostrum contents included potassium, sodium, calcium, magnesium, zinc, iron, rubidium, copper, strontium and aluminum. The contents of calcium, strontium, cesium, molybdenum, cobalt, uranium and thorium in the colostrum were significantly higher than those in the peripheral blood (P<0.05). There were significant correlations in the contents of sodium, rubidium, selenium, strontium, cesium, arsenic, mercury and cadmium between the colostrum and peripheral blood (P<0.05). In addition, there were significant correlations between some minerals in the colostrum, for example potassium vs manganese (r=-0.236, P=0.043), rubidium (r=0.816, P<0.001) and magnesium (r=0.400, P<0.001); sodium vs selenium (r =0.509, P<0.001), cerium (r=0.353, P=0.002), praseodymium (r =0.337, P=0.003) and thulium (r=0.331, P=0.004); calcium vs iron (r=0.251, P=0.031) and strontium (r =0.365, P=0.001); magnesium vs cesium (r=0.314, P=0.006) and copper (r =0.395, P=0.001); zinc vs selenium (r=0.310, P=0.007), cerium (r=-0.229, P=0.050), gadolinium (r=-0.372, P=0.001) and yttrium (r=-0.380, P=0.001); rubidium vs titanium (r=-0.413, P<0.001); copper vs cesium (r=0.275, P=0.018); strontium vs uranium (r=0.439, P<0.001); cadmium vs molybdenum (r=0.379, P =0.001). Conclusion The correlations of the mineral contents between the colostrum and peripheral blood suggested that some mineral elements could be accumulated from blood to breast milk through various transport mechanisms. The correlations between the mineral elements in the colostrum showed that there were some interactions between these elements, indicating that maintaining the dynamic balance of mineral elements in human milk is very important for the health of their offspring.

Objective:To analyze the risk factors of systemic inflammatory response syndrome (SIRS) caused by wasp stings.Methods:A prospective case-control study was conducted to analyze the clinical data of 225 patients with wasp stings admitted to Taihe hospital of Shiyan City and Ankang Central Hospital from January 2014 to December 2018, including 131 males and 94 females, with the age of 49 (41, 60) years. The patients were divided into SIRS group ( n=62) and non-SIRS group ( n=163) according to the SIRS diagnostic criteria. The data were collected including gender, age, sting in the head, sting in waist and back, sting in the abdomen, sting in the limbs, number of stings, admission time, hospitalization day, and mortality. The plasma levels of interleukin(IL)-6 and IL-8 in peripheral blood of the patients were analyzed by ELISA method. The whole genome DNA was extracted from white blood cells, and the IL-6: -174G/C, -572G/C, -597G/A, -634C/G and IL-8: -251A/T, -738T/A, -845T/C, + 396T/G were selected for research. The PCR method was used to perform bidirectional sequencing and comparison after amplification, and record the genotyping and frequency. The risk factors of SIRS caused by wasp stings were investigated by univariate analysis and multivariate Logistics regression analysis. Results:(1) The two groups showed significant differences in sting in the limbs, sting in waist and back, sting in the abdomen, number of stings, hospitalization day and mortality ( P<0.01), while there were no significant differences in gender, age, sting in the head and admission time ( P>0.05). (2) ELISA test showed the plasma levels of IL-6 and IL-8 in SIRS group were higher than those in non-SIRS group ( P<0.01). (3) Three genotypes of CC, GC and GG were observed in IL-6-572G/C. There were significant differences in the frequencies of genotypes and alleles between SIRS group and non-SIRS group ( P<0.01). Three genotypes of AA, AT and TT were observed in IL-8 -251A/T. There were significant differences in the frequencies of genotypes and alleles between SIRS group and non-SIRS group ( P<0.01). (4)Univariate analysis showed sting in waist and back, sting in the abdomen, sting in the limbs, number of stings, IL-6-572G allele, IL-8-251T allele were related to SIRS caused by wasp stings ( P<0.01). (5)Multivariate Logistics regression analysis showed limb stings ( OR=2.15), number of stings ≥10 ( OR=11.10), IL-6-572G allele ( OR=3.91) and IL-8-251T allele ( OR=3.97) were significantly related to SIRS caused by wasp stings ( P<0.05 or 0.01). Conclusions:The plasma levels of IL-6 and IL-8 are increased in patients with SIRS after wasp stings. The limbs stings, number of stings ≥10, IL-6 -572G and IL-8 -251T are all independent risk factors for SIRS caused by wasp stings.

OBJECTIVE: To investigate the effects of Enalapril maleate folic acid tablets on carotid atherosclerosis in H type hypertension patients with type 2 diabetes mellitus (T2DM) and its potential mechanism.METHODS: In prospective control study, 182 H type hypertension patients with T2DM were selected from Chongqing People's Hospital during Jan. 2014-Jan. 2016, and then randomly divided into observation group and control group, with 91 cases in each group. All patients received basic or hypoglycemic treatment of premixed insulin; observation group was additionally given Enalapril maleate folic acid tablets (containing enalapril maleate 10 mg, folic acid 0. 8 mg in each tablet) orally, one tablet, qd; control group was additionally given Enalapril maleate tablets (containing enalapril maleate 10 mg in each tablet) orally, one tablet, qd. Treatment course lasted for 12 months. The levels of blood pressure, plasma homocysteine (Hcy), fasting blood glucose (FBG), C-reactive protein (CRP) and carotid plaque score were detected in 2 groups before treatment, 12 months after treatment. RESULTS: Compared to before treatment, SBP and DBP of 2 groups were decreased significantly in 2 groups after 12 months of treatment (P<0. 05); there was no statistical significance between 2 groups (P>0. 05). The levels of plasma Hcy, FBG and CRP, carotid intima-media thickness and carotid plaque integral in observation group were significantly lower than control group (P<0. 05). CONCLUSIONS: Enalapril maleate folic acid tablets can relieve inflammation by reducing plasma Hcy, FBG and CRP so as to treat carotid atherosclerosis in H type hypertension patients with T2DM.

OBJECTIVEThis study aims to investigate the association between interleukin (IL)-10-597 (C/A) single-nucleotide polymorphisms and chronic periodontitis of Moyu Uygur population in Xinjiang Uygur Autonomous Region of China.

METHODSIn accordance with the inclusion and exclusion criteria, the buccal swabs of 300 subjects were randomly selected from the epidemiological investigation of Uygur adults in Moyu county on April and May 2013. The study was conducted on a healthy control group, a mild chronic periodontitis group, and a moderate-to-severe chronic periodontitis group, with each comprising 100 samples. The IL-10-597(C/A) site in the promoter sequences was analyzed using the tetra-primer amplification refractory mutation system-polymerase chain reaction method to test the genotype and allele distributions. Statistical analysis was performed using Chi-squared test and ordinal classification Logistic regression analysis.

RESULTSThe genotype and allele frequencies of the IL-10-597(C/A) site in the healthy control group, mild chronic periodontitis group, and moderate-to-severe chronic periodontitis group exhibited no significant difference (P>0.05). The age of all the samples was associated with chronic periodontitis. The risk of chronic periodontitis in the people of 55-65 years old was 25 times in the people under the age of 35 (OR=25.56, P<0.001).

CONCLUSIONSThe IL-10-597 (C/A) single-nucleotide polymorphisms in the gene promoter are not associated with chronic periodontitis in Uygur adult population.
