Objective:To investigate the expression of fibroblast growth factor 7 (FGF7) and related inflammatory factors in the serum of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:A case control study was conducted. The patients with AECOPD admitted to the First Affiliated Hospital of Xinjiang Medical University from November 2016 to January 2020 were enrolled. The patients were divided into mild group [forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio (FEV1/FVC) < 0.70, FEV1 percentage in predicted value (FEV1%) ≥ 80%], moderate group (FEV1/FVC < 0.70, 50% ≤ FEV1% < 80%), and severe group (FEV1/FVC < 0.70, 30% ≤ FEV1% < 50%) based on their lung function test results, with 20 patients in each group, and 20 patients with normal pulmonary function who underwent elective non-thoracic surgery such as gastrointestinal surgery and orthopedics surgery in the same period were selected as controls. The demographic data, FEV1/FVC, FEV1%, FVC, maximum mid-expiratory flow percentage in predicted value (MMEF%), 6-minute walking test (6MWT), and St George Respiratory Questionnaire (SGRQ) score were recorded respectively. Serum levels of FGF7, interleukins (IL-6, IL-1β) and tumor necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent assay (ELISA). Pearson correlation was used to analyze the correlation between TNF-α and lung function.Results:Compared with the normal pulmonary function group, the levels of FEV1/FVC, FEV1%, MMEF% and 6MWT in the mild, moderate and severe groups were significantly decreased, and the SGRQ scores were increased, the indicators continued to deteriorate with the aggravation of the disease, the statistical differences were found between severe group and normal pulmonary function group [FEV1/FVC: 0.39±0.09 vs. 0.81±0.04, FEV1%: (38.80±6.28)% vs. (109.58±13.80)%, MMEF%: (0.34±0.14)% vs. (2.69±0.99)%, 6MWT (m): 279.00±41.61 vs. 402.85±53.97, SGRQ scores: 34.95±6.71 vs. 2.60±2.06, all P < 0.05]. Compared with the normal pulmonary function group, the levels of FGF7 in the mild, moderate and severe groups were significantly lowered (ng/L: 6.31±2.65, 6.10±1.39, 6.64±1.77 vs. 8.29±3.51, all P < 0.05), but no significant difference was found among the mild, moderate and severe groups (all P > 0.05). Compared with the normal pulmonary function group, IL-6 and TNF-α levels were significantly increased in the mild, moderate and severe groups, and TNF-α increased with the aggravation of the disease, the statistical difference was found between severe group and normal pulmonary function group (ng/L: 7.42±2.28 vs. 3.83±0.92, P < 0.05). There was no significant difference in IL-1β level between the normal pulmonary function group and the mild, moderate, severe groups. Correlation analysis showed that TNF-α was negatively correlated with FEV1/FVC and FEV1% ( r values were -0.350 and -0.527, respectively, both P < 0.01). Conclusion:In AECOPD patients, serum FGF7 was decreased, while IL-6 and TNF-α were increased; however, with the aggravation of the disease, there was no significant change in the level of FGF7 in the peripheral blood, but the TNF-α level might be increased, accompanied by severe damage of small airway function.

Objective: To investigate the current status of HIV-related stigma among college students in Guilin,and to explore the impact of perspective-taking and empathy on HIV-related stigma among college students. Methods: The stratified cluster sampling method was used to select college students from 4 universities in Guilin city. Stratified randomization was used to assign all subjects into a control group (410) and an experimental group (396) for randomized controlled trials,and the HIV-related Stigma Questionnaire and the Basic Empathy Scale were used before and after the intervention. Results: Before the intervention of perspective-taking,there were no statistically significant differences between two groups in subscale scores and total scores of HIV-related stigma (t=0.80，0.35，-0.62，-0.10，P>0.05); However, signiticant differences in subscale scores and total score in HIV-related stigma were found after intervention (t=3.53，2.21，2.30，3.98，P<0.05). There was no statistically singnificant in the scores of all dimensions of empathy level and the total score before the intervention (t=0.10,-0.27,-0.08,P>0.05), dimensional score and total score in empathy were statistically significant after intervention (t=-2.15，-3.06，P<0.05). Empathy played an intermediary role of 14.08% between opinion selection and HIV stigma. Conclusion HIV-related stigma exists among college students in Guilin,and perspective-taking intervention effectively reduces its AIDS stigma. Empathy plays an intermediary role between them.

Objective To investigate MR T2-mapping in evaluating birth-related levator ani muscle injury.Methods 25 primiparas at 6 weeks after first vaginal delivery as primiparous group and 12 nulliparous volunteers as control group were prospectively studied. All the subjects underwent pelvic MRI including T2-mapping,mDIXON-T2 WI sequences.Levator ani muscle were divided into two subgroups:levator ani muscle injury group and non-injury group according to if there were edema,avulsion,or rupture in each levator ani muscle subdivisions[puborectal muscle(PRM);iliococcygeal muscle(ICM)],which were showed on mDIXON-T2 WI images.Two radiologists evaluated T2 values of PRM,ICM and observed artificial color images respectively.The consistency between two observers for T2 values of PRM,ICM were evaluated using the intraclass correlation coefficient (ICC ),the difference of T2 values in each levator ani muscle subdivisions among control group,non-injury group and muscle injury group were analyzed using ANOVA .Results There were 26 PRM injury cases and 24 non-injury cases in primiparous group on mDIXON-T2 WI images,and no ICM injured cases in our study.Inter-rater reliability for T2 values between two observers were good(ICC >0.75).T2 values in PRM injury group,non-injury group and control group were(62.78±1.23)ms,(49.75±3.17)ms,(49.96±4.37)ms respectively and the difference was significant. There were significant difference between PRM injury group and non-injury group,control group respectively(P =0.000,P =0.000). The T2 values of ICM in PRM injury group,non-injury group and control group were(70.80±6.50)ms,(62.41±7.32)ms,(62.78±6.91)ms and there were significant difference(P =0.000),meanwhile the difference between PRM injury group and non-injury group,control group were significant respectively(P =0.000,P =0.000).The color gradation of PRM in PRM injury group were mixed with blue, green,and yellow,and tone were lightened on T2-mapping artificial color images;ICM color gradation were uneven with green and yellow, a d tone were higher than those of control group and non-injurygroup.Conclusion T2-mapping can quantitatively assess birth-related levator ani muscle injury and T2-mapping artificial color images show the range and degree of levator ani muscle injury visually.It is hopeful to find micro lesions that T2 WI images are difficult to find.

Objective:To explore the serotype distribution and drug resistance of Shigella in stool samples of children under five years old with diarrhea from 2008 to 2017 in Sui County, Henan Province. Methods:A total of 4 721 stool samples of children under five years old with diarrhea were collected from Doufuyuan Clinic of Sui County during 2008 to 2017, and Shigella strains were isolated through bacterial culture. The slide agglutination test was used for serotyping of Shigella strains. Two hundred of seventy-one Shigella strains were selected in proportion, and multiple gradient polymerase chain reaction was used to detect virulence genes and Kirby-Bauer agar method was used for drug sensitivity. Trend chi square test was used to analyze the annual trend of drug resistance. Results:The detection rate of Shigella strains in 4 721 fecal samples was 20.69% (977/4 721). A total of 977 Shigella strains were divided into 13 serotypes in two groups, including 77.79%(760/977) Shigella flexneri strains and 22.21%(217/977) Shigella sonnei strains.The top three serotypes detected alternately every year.The dominant gene pattern of Shigella flexneri was Shigella enterotoxin ( shET)-1+ , shET-2+ , invasion plasmid antigen H ( ipaH)+ , invasion-associated locus ( ial)+ , accounted for 84.04%(179/213) and that of Shigella sonnei was shET-1-, shET-2+ , ipaH+ , ial+ , accounted for 46.55%(27/58). The drug resistance rates of 271 Shigella strains to ampicillin, nalidixic acid and tetracycline were more than 90% and the strains were more sensitive to cefepime and ceftazidime.The drug resistance rates to cefotaxime, cefepime, ciprofloxacin, chloramphenicol and sulfamethoxazole/trimethoprim increased year by year, and all had statistically significant differences ( χ2=24.027, 7.232, 6.039, 4.764 and 6.809, respectively, all P< 0.05). There were 98.52%(267/271) strains resistant to more than three kinds of drugs. The resistance rates of Shigella flexneri to ciprofloxacin, norfloxacin, and chloramphenicol were higher than those of Shigella sonnei, and the resistance rates to gentamicin and sulfamethoxazole/trimethoprim were lower than those of Shigella sonnei. The differences were statistically significant ( χ2=31.866, 14.868, 83.036, 68.534 and 14.738, respectively, all P<0.01). Conclusions:The major serotypes of Shigella in children under five years old in Sui County are constantly changing from 2008 to 2017. The dominant gene patterns of different serotypes are different. Most isolated strains have multiple drug resistances, and different serotypes have different resistance profiles.

KDM5B is a histone H3K4me2/3 demethylase. The PHD1 domain of KDM5B is critical for demethylation, but the mechanism underlying the action of this domain is unclear. In this paper, we observed that PHD1KDM5B interacts with unmethylated H3K4me0. Our NMR structure of PHD1KDM5B in complex with H3K4me0 revealed that the binding mode is slightly different from that of other reported PHD fingers. The disruption of this interaction by double mutations on the residues in the interface (L325A/D328A) decreases the H3K4me2/3 demethylation activity of KDM5B in cells by approximately 50% and increases the transcriptional repression of tumor suppressor genes by approximately twofold. These findings imply that PHD1KDM5B may help maintain KDM5B at target genes to mediate the demethylation activities of KDM5B.
