Objective To investigate the role and mechanism of simvastatin on colonic fibrosis in rats with 2,4,6-trinitrobenzene sulphonic acid (TNBS) induced colitis.Methods Forty-eight healthy male Sprague-Dawley rats were evenly divided into six groups:control group,TNBS group,simvastatin treated group Ⅰ,group Ⅱ (from zero to 21 days after modeling,simvastatin 5 mg/kg or simvastatin 20 mg/kg treated),group Ⅲ and group Ⅳ (from seven to 21 days after modeling,simvastatin 5 mg/kg or 20 mg/kg treated).Body weight and disease activity index (DAI) of the rats were inspected,and general colon,histological injury and fibrosis were scored.The expressions of collagen types Ⅰ and connective tissue growth factor (CTGF) at mRNA level were detected by reverse transcription-polymerase chain reaction (RT-PCR).The expressions of collagen types Ⅰ,CTGF and phosphorylation of myosin phosphatase target subunit-1 (p-MYPT-1) at protein level were determined by Western blotting.The data were analyzed by one-way ANOVA.Results Compared with control group,the colon length shortened,while colon weight,DAI score,general colon score,histological injury and fibrosis score significantly increased in TNBS group.And the expressions of collagen types Ⅰ also obviously increased.After intervention of simvastatin,both the colon length and weight of rats were improved.The DAI score,general score,histological injury and fibrosis score were lower than those of TNBS group.The expressions of collagen types Ⅰ,CTGF and p-MYPT-1 (group Ⅰ:0.68±0.22 ; group Ⅱ:0.59 ± 0.27 ; group Ⅲ:0.71 ± 0.20 ; group Ⅳ:0.59± 0.25) in colonic tissue were all lower than those of TNBS group (F=5.169,P＜0.05).There were no statistical significance among four groups (al1 P＞0.05).Conclusion Simvastatin can effectively prevent TNBS-induced rat colitis from colonic fibrosis,the mechanism may be related with Rho-kinase inhibition and down-regulation of CTGF over-expression.

Objective:To investigate the marital adjustment status of breast cancer patients after surgery and analyze its influencing factors.Methods:Using the convenient sampling method, postoperative breast cancer patients who were treated in 3 ClassⅢ Grade A hospitals in Shanghai from June 2017 to December 2018 were selected as the research objects. The general information questionnaire, Revised Dyadic Adjustment Scale (RDAS) , Breast Cancer Self-Efficacy Scale (BCSES) , Body Image Scale (BIS) , Hospital Anxiety and Depression Scale (HADS) and Medical Outcomes Study Social Support Survey (MOS-SSS) were used for investigation. Univariate analysis, Pearson correlation analysis and multiple linear regression were used to analyze the influencing factors of marital adjustment. In this study, a total of 300 questionnaires were issued and 240 valid questionnaires were returned. The effective recovery rate was 80.0%.Results:The total score of RDAS for postoperative breast cancer patients was (48.88±10.38) . The results of Pearson correlation analysis showed that marital adjustment of postoperative breast cancer patients was positively correlated with self-efficacy, body image, and medical and social support ( r=0.357, 0.382, 0.507; P<0.01) , and it was negatively correlated with anxiety and depression ( r=-0.362, -0.373; P<0.01) . The results of multiple linear regression analysis showed that awareness of tumor staging, actual support, self-acceptance and body image were the influencing factors of marital adjustment in patients after breast cancer surgery ( P<0.05) , explaining 32.9% of the total variation. Conclusions:The marital adjustment ability of patients after breast cancer surgery is at a moderate level. The awareness of tumor staging, actual support, self-acceptance and body image are factors that affect the patients' marital adjustment. It is necessary to actively formulate targeted intervention measures to enhance the psychological adjustment ability of patients in order to improve the ability of marriage adjustment.

Objective:To evaluate the reliability and validity of the Chinese version of the Ohkuma questionnaire.Methods:The Ohkuma questionnaire was translated and revised, before it was used to investigate 70 elderly patients. Cronbach′s alpha coefficient, Cohen′s kappa coefficient and Pearson correlation were used to evaluate the scale′s internal reliability, sub-item retest reliability and total score retest reliability. KMO and Bartlett tests were used to evaluate the validity. The correlation between the Chinese version of the Ohkuma questionnaire and ratings from video fluoroscopy before and after treatment was used to evaluate the scale′s discrimination ability.Results:The Cronbach′s alpha of the Chinese version of Ohkuma questionnaire was 0.831, with 0.814 in the initial evaluation and 0.808 in a second evaluation. The Cohen′s kappas of the 15 sub-items ranged from 0.728 to 1.000. The Pearson correlation coefficient of the total score was 0.914. The scale′s KMO value was 0.701. A t-test of the Ohkuma scores before and after treatment showed a statistically significant difference.Conclusion:The revised Chinese Ohkuma questionnaire has good reliability, validity and discriminatory power. It can be used to screen for dysphagia among the elderly.

Objective:To analyze the epidemic characteristics and trends of newly reported HIV-infected people among Chinese and Burmese in Dehong Dai and Jingpo Autonomous Prefecture (Dehong Prefecture) of Yunnan Province, China, from 2000 to 2023, and provide evidence for formμlating AIDS prevention and control measures for the Burmese living in Dehong.Methods:The data were obtained from the Chinese Disease Control and Prevention Information System. The distribution of HIV-infected people with different population characteristics was analyzed, and the Joinpoint regression model was used to analyze the temporal trend of crude detection rate in different genders, ethnicities, and ages.Results:From 2000 to 2023, 24 989 newly HIV infections were reported in Dehong Prefecture, of which 14 594 (58.4%) were Chinese and 10 395 (41.6%) were Burmese. Compared with Chinese, Burmese women (32.9%, 3 416/10 395), those aged 20-29 (40.9%, 4 248/10 395), and Jingpo people (26.7%, 2 773/10 395) accounted for a higher proportion. The new diagnosis rate of Chinese nationals increased from 1.0/10 000 in 2000 to 15.4/10 000 in 2004, and then showed a downward trend, falling to 1.2/10 000 in 2023. Among them, compared with other age groups, Dai and other ethnic groups and women, the new diagnosis rate among 20-49 age group, Jingpo and men were relatively higher, at 1.7/10 000, 2.3/10 000 and 1.3/10 000 respectively. Regarding the method of detection, the Chinese HIV-infected people were mainly detected by key population testing (35.7%), while the Burmese HIV-infected people by key population testing (28.9%) and physical examination for entry-exit personnel (25.3%). The transmission routes of both nationalities were mainly heterosexual transmission, but compared with Chinese HIV-infected persons, the proportion of Burmese infected persons through non-marital non-commercial transmission was relatively higher (66.4% vs. 60.6%). The proportion of Chinese nationals with a first CD4 +T lymphocyte (CD4) counts of <200 cells/μl (28.9%) was higher than that of Burmese nationals (19.8%). Conclusions:The rising trend of HIV infection among Chinese and Burmese people in Dehong Prefecture from 2000 to 2023 slowed down. The new diagnosis rate was higher in the 20-49 age group, Jingpo and men. Compared with Burmese HIV-infected people, the proportion of Chinese HIV-infected people with first CD4 counts <200 cells/μl was relatively higher. Comprehensive interventions should be further carried out for Myanmar nationals, and efforts should be made to expand testing for Chinese nationals.

ObjectiveTo determine the characteristics， viral load and immunological status of HIV-infected persons and their spouses who became HIV-positive， and the reasons for HIV seroconversion in 55 HIV discordant couples in Dehong Dai and Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunan Province. MethodsData on the 55 couples meeting the criteria of having a previously positive spouse were retrieved from the AIDS Integrated Prevention and Control Data Information System of the China Disease Control and Prevention Information System during 2015-2021. General socio-demographic information， age at diagnosis， exposure history， CD4⁺T lymphocyte count， and antiviral treatment were collected. Descriptive analysis and chi-square test were used to compare the distribution of pre-HIV-positive spouses and their HIV seroconverted spouses. ResultsA total of 55 spouses from HIV discordant couples had HIV seroconversion. Of them， 72.7% （40/55） of pre-HIV-positive spouses were husbands. The most recent CD4⁺T lymphocyte count in the pre-HIV-positive spouses was （328.31±246.27） cells·μL^-1 at the time of diagnosis of their seroconverted spouses， of which 36.3% （20/55） had a CD4⁺T lymphocyte count of less than 200 cells·μL^-1. Furthermore， of those pre-HIV-positive spouses with low CD4⁺T lymphocyte count， 45.0% （9/20） had an undetectable viral load， 15.0% （3/20） <400 copies·mL^-1， and 25.0%（5/20） ≥400 copies·mL^-1. Additionally， 16.4% （9/55） of the pre-HIV-positive spouses did not have a viral load test. The main reasons for HIV seroconversion among HIV-negative spouses in the discordant couples were poor condom use， poor compliance with antiviral therapy， and treatment discontinuation. ConclusionThe follow-up management of HIV discordant couples should be strengthened in Dehong Prefecture， especially the monitoring of viral load levels and immunological status of pre-HIV-positive spouses， to improve their compliance with antiviral therapy and reduce treatment discontinuation， which would effectively prevent and control HIV transmission between spouses.

ObjectiveTo understand the epidemiological characteristics and trends of sexually transmitted diseases （STDs） in Dehong Prefecture， Yunnan Province from 2010 to 2022， so as to provide a basis for the prevention and control of STDs in Dehong Prefecture. MethodsThe 2010‒2022 epidemic cards of STD cases in Dehong Prefecture were downloaded from the China Disease Control and Prevention Information System， and descriptive analysis of the incidence rate and demographic characteristics by disease type was conducted. The syphilis screening data of various populations in Dehong Prefecture between 2014 and 2022 were obtained from the National STD Control and Management Information System， and the syphilis positivity rates of key populations were calculated. ResultsA total of 18 225 STD cases were reported in Dehong Prefecture from 2010 to 2022， and the reported incidence rate increased from 17.1/10⁵ in 2010 to 172.0/10⁵ in 2022， showing an increasing trend （χ²_trend=42.9， P<0.001）. The number of reported cases of gonorrhea， syphilis， condyloma acuminatum， genital chlamydia infection， and genital herpes were 7 801 （42.8%）， 4 563 （25.0%）， 3 462 （18.8%）， 1 660 （9.1%）， and 775 （4.3%）， respectively. The majority of the reported STD cases were males （12 336 cases， 67.7%）， young adults aged 15 to <45 years （15 839 cases， 87.2%）， and farmers （9 230 cases， 50.7%）. The elderly group aged 65 years and over accounted for 10.5% of syphilis cases. Among different types of key populations， the highest syphilis positivity rate was found among men who have sex with men （10.1%）， followed by STD clinic attendees （8.1%）， and the syphilis positivity rates among clandestine prostitutes， voluntary counseling and testing population， drug addicts， and drug rehabilitation center/re-education through labor center population were 2.2%， 1.6%， 1.4%， and 1.3%， respectively. ConclusionFrom 2010 to 2022， the STD epidemic in Dehong Prefecture showed a rapidly increasing trend， with a higher incidence of gonorrhea and syphilis， and a higher syphilis positivity rate among men who have sex with men， drug addicts， clandestine prostitutes， and STD clinic patients. In the future， publicity， education and behavioral interventions for these groups should be strengthened to reduce the prevalence and transmission of STDs.
