To analyze the correlation of ADH4 exon rs1126671 and ADH7 exon rs971074 polymorphisms with risky drinking behaviors and alcoholic liver disease. The patients with alcoholic liver disease diagnosed in the Gastroenterology Department of the People′s Hospital of Hechi from November 2021 to June 2022, including 52 cases of alcoholic liver disease with positive risky drinking behaviors, 103 cases of non-alcoholic liver disease with positive risky drinking behaviors of the same gender and age, and 105 healthy subjects with no risky drinking behaviors as control groups were retrospectively analyzed. The serum total protein and albumin are detected by immunoturbidimetry and globulin is calculated by the difference method; the serum total bilirubin and direct bilirubin are detected by the nitrite oxidation method and indirect bilirubin is calculated by the difference method; alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and γ-glutamyl transferase are detected by the substrate method. The results revealed that all 52 patients with alcoholic liver disease were male. The non-parametric independent sample Kruskal-Wallis test was adopted to analyze the baseline of twelve liver functions among the alcoholic liver disease group, the risky drinking behavior group and the healthy control group, and it was found there was statistical significance in ten major liver function indicators in the difference comparison among the three groups like serum total protein (g/L) 65.0 (60.1, 71.4), 73.4 (70.3, 76.3), 72.4 (69.2, 76.2) ( H=37.130, P<0.001); albumin (g/L) 36.1 (28.6, 42.9), 47.2 (45.0, 49.2), 47.5 (45.9, 49.5) ( H=14.503, P=0.001); direct bilirubin (μmol/L) 10.1 (35.6, 34.0.1), 3.8 (3.1, 5.45), 4.2 (2.9, 6.0) ( H=26.608, P<0.001); alkaline phosphatase (U/L) 106.0 (71.0, 164.0), 68.0 (57.5, 82.0), 70.0 (59.0, 87.0) ( H=27.904, P<0.001); albumin to globulin 1.34 (0.91, 1.88), 1.82 (1.65, 2.00), 1.89 (1.68, 2.07) ( H=11.047, P=0.004); direct bilirubin to indirect bilirubin 0.91 (0.69, 1.91), 0.41 (0.35, 0.54), 0.42 (0.34, 0.54) ( H=19.478, P<0.001); serum total bilirubin (μmol/L) 23.9 (13.7, 51.0), 13.8 (10.2, 17.9), 13.0 (10.1, 17.4) ( H=18.375, P<0.001); aspartate aminotransferase (U/L) 74.0 (39.0, 122.0), 22.0 (19.0, 28.0), 23.0 (19.0, 30.0) ( H=76.365, P<0.001); alanine aminotransferase (U/L) 37.0 (25.0, 55.0), 23.0 (17.0, 30.0), 24.0 (17.0, 33.8) ( H=57.041, P<0.001); γ-glutamyl transferase (U/L) 135.0 (45.0, 364.0), 33.0 (23.5, 49.5), 32.0 (19.0, 49.0) ( H=82.558, P<0.001); however, there were no statistical significance in the pairwise comparisons between risky drinking and healthy groups. The two loci of ADH4 and ADH7 were in genetic linkage equilibrium. In the three groups of samples, the ADH4 gene rs1126671 locus was comprised primarily of the CC homozygous genotype, and there was no TT genotype. The ADH7 gene rs971074 genotype had statistical difference in the comparison of the three groups ( χ2=9.370, P<0.05). Compared with the CC genotype, the CT genotype had no statistical difference in the pairwise comparison between the risky drinking behavior group and alcoholic liver disease group, and the healthy group and alcoholic liver disease group. There was a statistical difference in that between the healthy group and the risky drinking behavior group ( χ2=6.372, P=0.012). The analysis display of mode of inheritance between RD group and HA group was statistically significant in the difference of the superdominance inheritance mode ( OR=2.92, 95% CI:1.22-6.98; P=0.012), the dominant inheritance mode ( OR=2.90, 95% CI:1.26-6.64; P=0.008), the co-dominant inheritance mode ( OR=2.96, 95% CI:1.24-7.08; P=0.032) and the additive mode ( OR=2.46, 95% CI:1.16-5.22; P=0.013). In general, the CT genotype of ADH7 gene rs971074 is a risk factor for positive risky drinking behavior, and the ADH family may still increase the susceptibility of people with a potential alcoholic liver disease protection background through the correlation between ADH7 and risky drinking behavior.

Objective To investigate the effect of schisandrin (SCH) treatment on learning and memory abilities and their mechanism in APP/PS1 dual transgenic dementia mice,and explore the effect of Chinese medicine on Alzheimer's disease (AD).Methods Thirty-five APP/PS1 dementia mouse models were randomly assigned into APP/PS1 model group (n=17) and APP/PS1+SCH group (n=18);another 10 male C57BL/6J mice were chosen as blank control group.The mice in the APP/PS1+SCH group were given intragastric administration of SCH at 2.6 mg/(kg· d) for 30 d;the mice in the APP/PS1 model group and blank control group were treated with distilled water for 30 d.The learning and memory abilities of these APP/PS1 mice (n=7) were detected by Morris water maze.Mice from the three groups were sacrificed;Nissl staining was used to observe Nissl bodies of neurons in brain tissues;real-time fluorescence quantitative PCR (qPCR) was used to detect the mRNA content of terminal glycosylationend products receptor (RAGE) in brain tissues;Western blotting was used to detect the expressions of RAGE and phosphorylated P38 mitogen-activated protein kinase (p-p38) in brain tissues.Results (1) The results of water maze space exploration experiment showed that the times of crossing the platform area in the three groups were statistically significant (P＜0.05);as compared with the APP/PS1 modelgroup,the times of crossing the platform area in the APP/PS1+SCH group were significantly increased (P＜0.05).(2) Nissl staining results showed that the contents of Nissl bodies in the hippocampal CA1 area and cortical neurons of the APP/PS 1 model group were significantly reduced,with light staining and cell body atrophy;the lesions in mice of the APP/PS1+SCH group were less severe than those of APP/PS1 model group,some neurons were atrophic,and the content of the neuronal nileite bodies in the hippocampal CA1 region was relatively abundant.(3) The qPCR results showed that there were statistically significant differences in RAGE mRNA expression levels in the cortex and hippocampus of the three groups (P＜0.05);as compared with the APP/PS1 model group,the APP/PS1+SCH group had significantly reduced RAGE mRNA expression in the hippocampal area (P＜0.05).(4) Western blotting results showed that RAGE and p-p38 protein expression levels in two parts of mice of APP/PS1+SCH group were significantly reduced as compared with those in the APP/PS1 model group (P＜0.05).Conclusion SCH may improve the functional status of hippocampal and cortical neurons and improve the spatial exploratory memory ability of APP/PS1 mice by down regulating the RAGE and P38 expressions.

Objectives To access the bacteriology in patients with sepsis due to biliary tract infection to provide a basis for empirical selection of proper antibiotic treatment.Methods This is a single-center retrospective study on 214 patients with biliary tract infection admitted from August 2014 to July 2016 to the surgical intensive care units (ICU) of The First Affiliated Hospital of Sun Yat-sen University.To study the demographic information,sequential organ failure assessment (SOFA),usage of antibiotics before ICU and duration of ICU were analyzed.Bile,peritoneal drainage and blood samples were collected.Results 47 septic shock patients and 25 septic patients due to biliary tract infection were enrolled in the trial.The two groups (the shock group vs.the sepsis group) had a significant difference in the duration of ICU stay [(6.4 ± 4.6) d vs.(2.3 ± 1.8) d,P ＜ 0.05].48 strains of pathogens were isolated from the bile samples.The major pathogens were Escherichia coli (E.coli) (n =23,47.9％),Enterococcus faecalis (n =8,16.7％) and Enterococcus faecium (n =2,4.2％).80 strains of pathogens were isolated from the peritoneal drainage culture samples.E.coli,pseudomonas aeruginosa,and Klebsiella pneumoniae ranked the top 3 species,accounting for 26.3％,11.3％ and 7.5％,respectively.The sensitivity of E.coli isolated from bile to amikacin,imipenem and panipenem were all over 90.0％.Conclusions E.coli was the principal gram-negative bacterium in biliary infection induced sepsis.Early administration of carbapenemes may reduce the occurrence of septic shock in these patients.

Objective To investigate the effects of Dihuang Yinzi (DY) on the receptor for advanced glycation end-products(RAGE)/reactive oxygen species(ROS)/apoptosis pathway in SH-SY5Y cells induced by amyloid-beta1-42 (Aβ1-42) oligomer. Methods Firstly, we adopted methyl thiazolyl tetrazolium(MTT) method to detect the cell vitality in fetal bovine serum (FBS) group, blank serum group, and low-, middle- and high- dose DY-containing serum groups, so as to confirm the optimal concentration and treatment time of DY-containing serum. Secondly, we applied MTT method to detect cell vitality and applied Annexin V/propidium iodide (PI) staining method to observe the apoptosis of SH-SY5Y cells treated with 0~20 μmol/L Aβ1-42 for 24 and 48 h, so as toconfirm the optimal concentration and treatment time of Aβ1-42 for establishing Alzheimer's disease (AD) model in vitro. Thirdly, MTT method was used for the detection of cell vitality, and Annexin V/PI staining method was used for detection of the apoptosis of SH-SY5Y cells in blank serum group, model group, western medicine control group and low-, middle-and high-dose DY-containing serum groups, and Dihydroethidium (DHE) method was used for the assay of ROS contents, so as to observe the effect of DY on the recovery of injured SH-SY5Y cells induced by Aβ1-42. Finally, we applied Western blot method to detect the expression level of RAGE in SH-SY5Y cells of blank group, model group and DY-containing serum group; after Aβ1-42-induced SH-SY5Y cells were transfected with RAGE gene, we adopted DHE staining method and Annexin V/PI staining method to detect ROS content and cell apoptotic rate in all of the above groups, so as to observe the effect of DY on SH-SY5Y cell apoptosis and RAGE expression. Results The cell vitalities were increased in low- and middle-dose DY-containing serum groups at 24 h (P < 0.05 or P < 0.01 compared with that in the blank serum group). The conditions for the establishment of AD model in vitro were as follows: the optimal concentration of Aβ1-42 was 5μmol/L, and the treatment time was 24 h. The cell vitalities were significantly enhanced, the cell apoptotic rate and ROS content were significantly lowered in Aβ1-42-induced SH-SY5Y cells of the medication groups(P <0.05 or P < 0.01 compared with those in the model group) , and the cell vitality was the highest and the cell apoptotic rate was the lowest in the middle-dose DY-containing serum group. The RAGE expression level was decreased in Aβ1-42-induced SH-SY5Y cells of the middle-dose DY-containing serum group(P < 0.05 compared with that in the model group) . ROS content and cell apoptotic rate were decreased in Aβ1-42-induced SH-SY5Y cells transfected with RAGE gene in the middle-dose DY-containing serum group (P<0.01). Conclusion DY may play an anti-oxidative role through inhibiting the production of ROS and cell apoptosis, thus to suppress RAGE protein and to achieve the preventive and therapeutic effect for AD.

Objective To investigate the effects of Dihuangyinzi(DHYZ) on behaviors and RAGE/p38 pathway in APP/PS1 mice.MethodTwenty APP/PS1 dementia mice were randomly divided into model group(n=10) and Chinese medicine group(n=10).The blank group was C57 BL/6 J normal mouse(n=10).The mice in Chinese medicine group were intragastric administration with DHYZ (9.75 g·kg-1·d-1).The mice in model group and blank group were treated with distilled water.After 30 days,the abilities of learning and memory of mice were detected by Morris water maze.The expression of amyloid-beta1-42(Aβ1-42) in the hippocampus and cortex was detected by immunohistochemistry.Reactive oxygen species of brain tissue were detected by DCFH-DA Methods in the brain of APP/PS1 mice.Gene expression level of receptor for advanced glycation end products(RAGE) was measured by real-time polymerase chain reaction (RT-PCR) in the cortex and hippocampus of APP/PS1 mice.The expression of phospho-mitogen-activated protein kinases (p38) was analyzed with Western blot and immunofluorescence analysis in the cortex and hippocampus of APP/PS1 mice.Results Behavioral Results showed that DHYZ significantly increased the distance((23.088±7.083)cm) and residence time((1.961±1.230)s)of effective area in Morris water maze on the fifth day(P<0.05,P<0.01)and remarkably increased the number of effective area crossings((1.607±0.405) times) and plats((0.893±0.283) times) in Morris water maze on the fifth day(P<0.01,P<0.05).DHYZ also significantly reduced the intracelluar ROS level(122.611±7.630) in the brain(P<0.01),and DHYZ could depress the expression of RAGE(1.467±0.081,7.983±0.136) and phosphorylation of p38 (0.376±0.026,0.538±0.016)in the cortex and hippocampus of APP/PS1 mice(P<0.01,P<0.05).Conclusions The Results demonstrate that DHYZ can partly improve memory impairment of APP/PS1 mice by the inhibition of RAGE/p38 pathway.
