Objective To explore the status quo of depression and medical-social support in human immunodeficiency virus(HIV)/acquired immunodeficiency syndrome(AIDS)hemodialysis patients,as well as the effect of medical-social support on depression.Methods A total of 80 HIV/AIDS hemodialysis patients from Xixi Hospital in Hangzhou from March 2022 to March 2024 were collected.Center for epidemiological survey-depression scale(CES-D)and medical social support scale(MOS-SSS)were used to assess patients for depression and medical social support.Structural equation model was used to analyze relationship between medical social support and depression.Results 42 of the 80 subjects(52.5%)had depressive symptoms(CES-D score≥16 points).The results of univariate analysis showed that health status,antiviral treatment status,medical social support had an impact on HIV depression(P<0.05).Simple linear regression showed that health status(95%CI:-9.901--2.635)and antiviral treatment status(95%CI:-12.969--3.394)were the influencing factors for depression(P<0.05).The total score of medical social support,tangible support dimension,information and emotional support dimension,positive social interaction dimension,emotional support dimension were associated with depression(P<0.001).Multiple linear regression analysis showed that medical social support was negatively associated with depression.The higher medical social support was the lower incidence of depression.Conclusion The prevalence of depression in AIDS hemodialysis patients is high,and medical social support has a positive effect on alleviating their condition.

Objective To establish the primary cat intestinal epithelial cells(IECs)culture methods and construct the cD-NA library for the following yeast two-hybrid experiment,so as to screen the virulence interaction factors among the final host. Methods The primary cat IECs were cultured by the tissue cultivation and combined digestion with collagenase XI and dispase I separately. Then the cat IECs cultured was identified with the morphological observation and cyto-keratin detection ,by using goat anti-cyto-keratin monoclonal antibodies. The mRNA of cat IECs was isolated and used as the template to synthesize the first strand cDNA by SMARTTM technology,and then the double-strand cDNAs were acquired by LD-PCR,which were subsequently cloned into the plasmid PGADT7-Rec to construct yeast two-hybrid cDNA library in the yeast strain Y187 by homologous recom-bination. Matchmaker?Insert Check PCR was used to detect the size distribution of cDNA fragments after the capacity calcula-tion of the cDNA library. Results The comparison of the two cultivation methods indicated that the combined digestion of colla-genase XI and dispase I was more effective than the tissue cultivation. The cat IECs system of continuous culture was established and the cat IECs with high purity were harvested for constructing the yeast two-hybrid cDNA library. The library contained 1.1× 106 independent clones. The titer was 2.8 × 109 cfu/ml. The size of inserted fragments was among 0.5-2.0 kb. Conclusion The yeast two-hybrid cDNA library of cat IECs meets the requirements of further screen research,and this study lays the foundation of screening the Toxoplasma gondii virulence interaction factors among the cDNA libraries of its final hosts.

Objective To explore the biological function of rhoptry protein 38(ROP38)of Toxoplasma gondii,and to iden?tify the reactogenicity of the recombinant protein(rROP38). Methods The ROP38 was amplified by RT?PCR from T. gondii RH strain,and was cloned into prokaryotic expression vector pET?28a(+). The recombinant plasmid was transformed into E. co?li BL21(DE3)competent cells. Then the rROP38 was analyzed by SDS?PAGE and identified by Western blot. Results SDS?PAGE showed that rROP38 was efficient expression with a molecular weight of about 43 kD. Western blot showed that rROP38 reacted with antibody of His tag or human positive antibody,which indicated that ROP38 had good reactogenicity and could be a serological diagnostic antigen. Conclusion The study successfully obtains the rROP38 of T. gondii with good reactogenicity.
