Objective:To explore the effects of perceived stress on ego depletion of college students, as well as the mediating role of emotional eating and the moderating role of peer relationship.Methods:A cross-sectional survey of 1 088 college students was conducted using the perceived stress scale, the Dutch eating behavior questionnaire, the self-control resource depletion scale, and the peer relationship measurement from December 2023 to April 2024.PROCESS Macro program in SPSS 25.0 software was used to test the mediating effect of emotional eating and the moderating effect of peer relationship.Results:(1)The score of perceived stress, emotional eating, peer relationship and ego depletion were 39.26±8.35, 39.19±12.15, 2.00(1.00), and 18.19±7.15, respectively.(2)Perceived stress was positively correlated with emotional eating, ego depletion, and peer relationship( r=0.36, 0.61, 0.25, all P<0.01). Emotional eating was positively correlated with ego depletion and peer relationship( r=0.40, 0.19, both P<0.01). And ego depletion was positively correlated with peer relationship( r=0.23, P<0.01).(3)Emotional eating played a partial mediating role in the effect of perceived stress on ego depletion( β=0.077, 95% CI=0.053-0.104), and the mediating effect accounted for 12.38%(0.077/0.622) of the total effect.(4)Peer relationship played a moderating role between perceived stress and emotional eating. Under low peer relationship, perceived stress had a significant positive predictive effect on emotional eating( βsimple=0.46, P<0.01), and under high peer relationship, the predictive effect of perceived stress on emotional eating was significantly weaker( βsimple=0.26, P<0.01). Conclusions:Perceived stress not only directly affects ego depletion, but also indirectly affects ego depletion through emotional eating in college students.High levels of peer relationship can weaken the impact of perceived stress and high emotional eating on ego depletion.

Ninety eight patients with chronic hepatitis B (CHB) admitted to Department of Infectious Diseases, Yongkang First People′s Hospital from January 2017 to June 2018 were randomly divided into two groups. On the basis of entecavir+dicyclool treatment, patients in control group (48 cases) received health education and weekly telephone follow-up from the nurses, while patients in intervention group (50 cases) received health guidance from doctors and psychological counseling and communication from the nurses. All patients were followed up for 8 weeks. The illness perception, negative emotions, quality of life, and medication compliance were evaluated with the Revised Illness Perception Questionnaire (IPQ-R), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), SF-36 and Morisky Medication Adherence Scale (MMAS-8) in two groups, respectively. The results showed that, after 8 weeks, the disease identity, serious consequences, treatment control and disease correlation; SAS and SDS scores; physiological function, emotional function, energy and social function were significantly improved in control group( t=2.30, 3.45, 2.35, 2.23, 5.04, 6.03, 2.03, 2.79, 2.02, 2.34, all P<0.05). All dimension of illness perception; SAS and SDS scores; physiological function, physiological function, emotional function, energy, mental health, social function and general health were also improved significantly in intervention group ( t=4.06, 5.44, 6.91, 8.53, 5.65, 8.77, 7.25, 6.06; 12.71, 11.91, 2.27, 2.60, 4.48, 2.82, 3.65, 3.461, 2.82,all P<0.05). And the personal control, disease correlation and emotional expression; SAS and SDS scores; emotional function and mental health in intervention group were better than those in control group ( t=1.49, 2.74, 2.60, 5.02, 5.18, 5.56, 13.72, all P<0.05). In addition, the medication compliance of patients in both groups was significant improved ( Z=5.56, 13.72, all P<0.01), and the improvement was more marked in the intervention group ( Z=3.22, P<0.01). The study indicates that the comprehensive psychotherapy can more significantly improve the degree of illness perception, negative emotions, quality of life and medication compliance in patients with chronic hepatitis B.

Objective To investigate the effect of Zingiber corallinum oil ( ZCO ) on apoptosis and proliferation of cervical carcinoma cell line HeLa. Methods HeLa cells were treated with different concentrations of ZCO(5-80 mg·L-1)in vitro. Cytotoxicity rate was determined by CCK-8 assay. The morphological changes was observed using inverted microscope after AO/EB staining. Caspase-3 activities were measured with a colorimetric method. Protein level of hsp-70 were detected by Western blotting. Cell cycle and apoptosis were analyzed by flow cytometer ( FCM ) . Results ZCO exhibited effect of proliferation inhibition and apoptosis-inducing on the growth of HeLa cells in a dose-dependent manner. Caspase-3 activities increased in a dose-dependent manner while the expression of hsp-70 decreased. Cell cycle was arrested in G2/M phase. Conclusion ZCO exhibites a marked effect of proliferation inhibition and apoptosis-inducing on HeLa cells. The mechanism of ZCO might be activating the key enzyme in apoptotic pathway, so that the expression of hsp-70 is down-regulated, and cell cycle is arrested in G2/M phase.

Objective To investigate the effects of an ar?turmerone derivative(ATD)on the proliferation and apoptosis of A375 human melanoma cells. Methods Both A375 cells and human skin fibroblasts (HSFs) were cultured with different concentrations(5, 10, 20, 40 and 80μmol/L)of ATD, vincristine and ar?turmerone, separately, for 48 hours in vitro. Subsequently, cell counting kit?8 (CCK?8) was used to evaluate cell proliferation, inverted microscopy to observe cell morphology after acridine orange/ethidium bromide (AO/EB) staining, and a colorimetric method to estimate caspase?3 activity. DNA fragmentation assay and flow cytometry were performed to assess cell apoptosis, and flow cytometry was conducted to analyze cell cycle. Results ATD, vincristine and Ar?turmerone all inhibited the proliferation of A375 cells in a dose?dependent manner(ATD:R2=0.99, F=340.96, P<0.05;vincristine:R2=0.99, F=349.19, P<0.05;ar?turmerone:R2=0.89, F=25.41, P<0.05). The fifty percent inhibitory concentra?tions(IC50s)of ATD, vincristine and ar?turmerone against A375 cells were 15.96 ± 0.02μmol/L, 77.00 ± 0.04μmol/L and 356.95 ± 0.01μmol/L respectively. When the drug concentrations were 5 and 10μmol/L, the proliferation of HSFs was inhibited by 8%± 0.06%and 25%± 0.02%respectively by ATD, by 49%± 0.09%and 34%± 0.07%respectively by ar?turmerone, and by 33%± 0.04%and 29%± 0.08%respectively by vincristine, and the proliferation of A375 cells was inhibited by 26%± 0.06%and 39%± 0.02%respectively by ATD, by 6%± 0.09%and 10%± 0.07%respectively by ar?turmerone, and by 8% ± 0.04% and 17% ± 0.08% respectively by vincristine, with the inhibitory effects of the three drugs being significantly different from that of dimethyl sulfoxide(all P<0.05). ATD showed stronger inhibitory effects on the proliferation of A375 cells, but weaker cytotoxic effects on HSFs compared with ar?turmerone and vincristine(all P<0.05). Meanwhile, ATD, vincristine and ar?turmerone all induced the apoptosis of A375 cells(P<0.05), and caspase?3 activity increased with the increase in drug concentrations(ATD:R2=0.98, F=162.30, P<0.05;vincristine:R2=0.96, F=94.39, P<0.05;ar?turmerone:R2=0.95, F=57.35, P<0.05). The effect of ATD on caspase?3 activity was strongest, followed by that of vincristine and ar?turmerone. As flow cytometry showed, all the three drugs induced cell apoptosis to different degrees, and ATD showed a relatively strong effect on cell apoptosis, especially late apoptosis, compared with the other two drugs. In the ATD group, the number of A375 cells in G1 phase gradually increased, while that in G2 phase and S phase significantly decreased with the increase in drug concentrations. Conclusions ATD exhibited proliferation?inhibiting and apoptosis?inducing effects on A375 cells, and the effects were stronger than those of vincristine and ar?turmerone. It is quite possible that ATD affects cell proliferation and differentiation by activating caspase?3 and arresting cell cycle in the G1 phase.

Objective To evaluate the efficacy of low-dose levothyroxine sodium in treatment of severe pulmonary tuberculosis with euthyroid sick syndrome(ESS). Methods One hundred and twenty inpatients with severe pulmonary tuberculosis and ESS were randomly divided into treatment group and control group by gender, age, disease duration and severity. Both groups were given anti- tuberculosis, antiinfection treatment and nutritional support for 2 weeks; patients in treatment group were given low-dose levothyroxine sodium additionally. Thyroid function, clinical improvements, increase of albumin, reduction of acid-fast bacilli, improvements on images and the mortality rates were compared between the groups.Results After 2 weeks of treatment, symptoms including fever, cough and night sweats were improved in both groups. Marked improvements were observed in 19 patients(31.7%)of treatment group and 8 patients (13.3%)of control group(χ2 = 5. 73, P ＜ 0.05). Clearance rate of acid-fast bacilli in treatment group was 25.0%(15/60), but that in the control was only 6.7%(4/60)(χ2 = 7. 50, P ＜ 0.01). Serum albumin in the treatment group was increased to(34.2 ±0.4)g/L after the treatment, and that in the control group was(29.1 ±0.6)g/L(t =2.42, P＜0.05). T3 and FT3 were significantly increased in both groups, but more significant difference was observed in the treatment group(t = 59. 42 and 50. 66, P ＜ 0. 01). No empty closed after treatment in both groups, but the effective rate in treatment group was significantly higher than that in the control group(93.3% vs. 76.7%, χ2 =6. 54, P＜0.05). Two patients in control group died(2/60, 3. 3%), while no death was reported in treatment group. Conclusions Low-dose levothyroxine sodium treatment is effective for ESS in patients with severe pulmonary tuberculosis.Improvement on low T3 syndrome may be an important indicator for the overall improvement or recovery.

OBJECTIVE To assay retrospectively the isolation rate and susceptibility of Staphylococcus aureus(SAU) in our hospital during five years.METHODS Qualified sputa had been collected by the clinical(microbiological)(laboratory) and cultured to identify the SAU,then evaluated its susceptibility to some commonly used antibiotics in clinic.At the same time,the ratio of SAU to all the other isolated pathogenic bacteria and to the Gram-positive bacteria was calculated.The standard criteria were based on 2000 National Committee for Clinical(Laboratory) Standards of the USA.RESULTS The ratio of SAU to all isolated bacteria was 16%,and to Gram-positive ones was more than 70%.There was no obvious difference among every two isolation rate per year.The(resistance) rate to the most of commonly used antibiotics was higher than 50%,while the resistance rate to(imipenem),amikacin,and netilmicin was very low.And the vancomycin-resistant SAU was not isolated.(CONCLUSIONS) The resistance of SAU is still a serious problem and in our lab there is no vancomycin-resistant strain.
