Objective:To explore the relationship between perceived responsiveness and mental health of col-lege students,as well as the mediating role of basic psychological needs and the moderating role of interpersonal problems.Methods:A total of 1 035 college students were assessed using the Perceptive Partner Responsiveness Scale(PPRS),Basic Psychological Needs Scale(BPNS),Inventory of Interpersonal Problems-Short Circumplex(IIP-SC),Mental Health Continuum Short Form(MHC-SF)and 12-item General Health Questionnaire(GHQ-12).Latent variable structural equation modeling was employed to examine the mediating role of basic psychological needs and the moderating effect of interpersonal problems.Results:The scores of PPRS were positively correlated with MHC-SF scores(β=0.76)and negatively correlated with GHQ-12 scores(β=-0.72).The scores of BPNS partially mediated the relationship between the scores of PPRS and MHC-SF,and PPRS and GHQ-12,accounting for 60.53%and 80.56%of the total effect,respectively.IIP-SC scores negatively moderated the relationship be-tween PPRS and BPNS(β=-0.10),and BPNS and GHQ-12(β=-0.06),while positively moderated the rela-tionship between BPNS and MHC-SF(β=0.13).Conclusion:Perceived responsiveness is associated with positive mental health,mental health problems,basic psychological needs and interpersonal problems among college students.

ObjectiveTo understand the epidemiological characteristics of syphilis in Ruian City, so as to provide a scientific basis for developing syphilis prevention and control strategies. MethodsDescriptive epidemiological methods were used to investigate the infection status of syphilis cases reported among the permanent resident population in Ruian City from 2014 to 2023, and its epidemiological characteristics were analyzed. ResultsA total of 5 482 syphilis cases were reported in Ruian from 2014 to 2023, with a male-female ratio of 1∶1.47. The average annual incidence rate from 2014 to 2023 was 37.51/100 000, with a declining trend in the incidence rate among females (APC=-4.78%, P<0.05). The incidence of primary and secondary syphilis decreased, while the proportion of latent syphilis cases increased. No cases of congenital syphilis were reported from 2017 to 2023. The majority of cases (60.29%) were reported among individuals aged 20‒<50 years. In terms of occupation, the highest proportion was found among housekeepers and the unemployed, constituting 42.70% the total cases. Dermatology departments reported the most cases in medical institutions, accounting for 33.38% of the total cases. The most likely route of infection was heterosexual transmission, accounting for 85.84%. ConclusionThe incidence of syphilis among females in Ruian City shows a declining trend, but the overall situation remains concerning. Prevention and control efforts should be intensified among key groups and high-risk populations, along with an enhancement on health education to curb the spread of syphilis.

Objective:To evaluate the effects of cellulift ? administered intradermally by mesotherapy on collagen synthesis in D-galactose induced aging model of rats. Methods:The study was conducted between April and October in 2014 in the Department of Anatomy, Qindao University. 30 male rats were randomly allocated to three groups: aging treatment group, aging control group and normal group; each group had ten rats. Aging treatment group and the control group were subcutaneously injected with D-galactose prepared in saline 125 mg·kg -1·d -1 for 42 day. Normal group was injected with saline for 42 d with same method and dose. From the 18th day after shaving their hair, the dermis of two sides hip skin marked zone of aging treatment group were injected cellulift at a dose of 1 ml per week for 4 weeks. Meanwhile, the aging control group was administrated the same volume of saline with same method. In vivo skin collagen alterations were investigated by reflectance confocal microscopy 3 days after every treatment. Skin specimens were obtained in 42 days. In order to measure the dermal collagen density and dermal thickness, HE and Masson trichrome staining were performed, respectively. Immunohistochemical staining for TGFβ1 and proliferating cell nuclear antigen (PCNA) was performed. Also, the level of TGFβ1, Smad3, types Ⅰ and Ⅲ pro-collagen mRNA expression was assessed by real-time quantitative polymerase chain reaction. Results:As revealed by RCM, collagen density of aging treatment group increased gradually after treatments, while in aging control group it decreased with time. Measurement of dermal thickness, hydroxyproline content and TGFβ-1 mRNA and protein expression in treatment group increased significantly as compared with that in aging control group, but were significantly lower than that in normal group (F values were 25.45, 98.90, 37.94 and 21.35, respectively; P<0.05). Measurement of dermal collagen density, the mRNA expression of type I pre-collagen and Smad3 elevated over that of aging control group with significant difference (F values were 44.46, 29.54 and 10.01, respectively; P<0.05), and there was no difference between normal and aging treatment group ( P>0.05). The difference of PCNA expression between aging control and treatment groups was not significant ( P>0.05), and both were lower than normal group ( P<0.05) . Conclusions:Cellulift ? shows anti-aging effects by activating collagen synthesis and eventually causing dermal thickening. This effect is probably mediated by TGF-β1/Smad3 signaling pathway.
