Objective: To investigate the mediating role of vaccine literacy between vaccine knowledge and vaccine hesitancy and the moderating role of parental education level, so as to provide references for adjusting vaccination strategies. Methods: From May to December 2024, a stratified random sampling method was used to select 10 community hospitals in Guiyang and Zunyi City, Guizhou Province. A total of 1 401 parents of children aged 0-6 years were surveyed regarding their socio demographic characteristics, vaccine knowledge, vaccine literacy, and vaccine hesitancy levels. Data were analyzed using common method bias tests, Spearman correlation analysis, mediation and moderation effects tests. Results: The mean score for vaccine knowledge, vaccine literacy and vaccine hesitancy were (2.96±1.11, 14.25±2.64, 39.12±4.93) among the 1 401 participants. Mediating effect analysis showed that both parental vaccine knowledge ( β =1.28, 95% CI =1.08-1.49) and vaccine literacy ( β =0.75, 95% CI =0.66-0.84) positively predicted vaccine hesitancy (both P <0.01). Meanwhile, vaccine literacy accounted for 28.1% of the total effect of mediation between knowledge and vaccine hesitancy. In the moderated effects analysis, education level positively predicted vaccine literacy ( β =0.40, 95% CI =0.24-0.57), and education level moderated the pathway of vaccine knowledge on vaccine hesitancy ( β = 0.28 , 95% CI =0.05-0.52) (both P <0.01). Conclusions Vaccine literacy partially mediates the relationship between vaccine knowledge and vaccine hesitancy. Parental education level positively moderates the prediction of vaccine knowledge on vaccine hesitancy score.

Objective To investigate nursing interns’knowledge and attitude towards needle stick injury before clinical practice.Methods In 20-23 June,2015,nursing interns who were about to start clinical practice in a hospi-tal were investigated,nursing interns’knowledge and attitude towards needle stick injury were surveyed through questionnaire.Results A total of 350 questionnaires were distributed,324 (92.57%)responded questionnaires were available.40(12.35%)questionnaires were responded by male interns,and 284(87.65%)were by female in-terns;34(10.49%)interns had bachelor degree;the mean age of interns were (20.83 + 1 .24)years old.The correct answer rates about questions related to injury occurring during needle recapping and wearing gloves were low (about 60%).About 70% of the interns gave the correct answers to questions about hepatitis B infection due to needle stick injury following hepatitis B vaccination,as well as medication after injury.Score for individual question about attitude towards needle stick injury was ≤3,the major related problems were susceptibility of blood borne diseases and recapping needles.Conclusion Needle stick injury-related knowledge and attitude among nursing interns is inadequate,including recapping needles,timely report,susceptible to infectious diseases,and so on.It is necessary for schools and teaching hospitals to strengthen the education about occupational protection among nursing interns, so as to improve the attitude and ability of professional protection.

Objective To evaluate the role of c-Jun N-terminal kinase (JNK) signaling pathway in paclitaxel-induced apoptosis in hippocampal neurons of rats, and the relationship with nuclear factor kappa B (NF-κB) pathway.Methods The primarily cultured hippocampal neurons were seeded in 96-well plate at a density of 1×106 cells/ml (200 μl/hole) , and were randomly divided into 4 groups (n=8 each) using a random number table: control group (C group), paclitaxel group (P group), JNK inhibitor SP600125 group (S group), and SP600125 + paclitaxel group (S+P group).Paclitaxel 2 ml (1 μmol/L) was added to group P.SP600125 2 ml (10 μmol/L) was added to group S.In group S+P, SP600125 2 ml (10 μmol/L) was added, the cell were then incubated for 1 h, and then paclitaxel 2 ml (1 μmol/L) was added.The cells were then incubated for 24 h.At 24 h of incubation, the apoptosis in hippocampal neurons was detected by flow cytometry, and the expression of NF-κB p65 was measured by Western blot.The apoptosis rate was calculated.Results Compared with group C, the apoptosis rate was significantly increased, and the expression of NF-κB p65 was up-regulated in P and S+P groups, and the apoptosis rate was significantly decreased, and the expression of NF-κB p65 was down-regulated in group S (P＜0.05).Compared with group P, the apoptosis rate was significantly decreased, and the expression of NF-κB p65 was down-regulated in group S+P (P＜0.05).Conclusion JNK signaling pathway mediates paclitaxel-induced apoptosis in hippocampal neurons of rats, and the mechanism is likely related to inhibition of NF-κB pathway activation.

ObjectiveTo assess the diagnosis and treatment of staphylococcal scalded skin syndrome (SSSS)in children.MethodsA total of 177 children whh SSSS were eligible for this study.Clinical data were retrospectively reviewed to assess the patients' age and geographical areas,predisposing factors,prodrome,clinical features,results of laboratory examination(including bacterial isolation and drug susceptibility test),treatment and prognosis.ResultsThe median age at onset was 23 days past 15 months.Infants aged 1 to 3 years were the most commonly affected population.The male to female ratio was 8:9.SSSS occurred in summer or autumn in 71.2％ of the patients.Most patients came from countryside.Of these patients,148 (83.6％) had no definite inducement,13 (7.3％) had fever or cold history before the occurrence of SSSS.Skin lesions often began in the face(71.6％).Almost all cases presented with erythema and blisters.Abnormal myocardial enzymes were observed in 104(80.6％) of 129 patients,and Staphylococcus aureus was isolated from 38.7％ of 142 patients.Susceptibility testing of 21 Staphylococcus aureus isolates from patients in the past 3 years showed that 95.2％ and 95.0％ were sensitive to cephalosporins and amoxicillin/clavulanic acid respectively.Double-antibiotic therapy was effective in 72.9％ of the patients.Intravenous gamma globulin was given to 36.2％ of the patients in the early stage.Myocardial-protecting drugs were also administrated early in patients with abnormal myocardial enzymes.All the patients healed without scarring.ConclusionsFor infants with acute facial erythema and exfoliative skin lesions,SSSS should be suspected and timely antibiotic treatment should be given.Cephalosporins and semi-synthetic penicillins are effective and the first choice for the treatment of SSSS.Meanwhile,early addition of gamma globulin and myocardial-protecting drugs may be beneficial to disease recovery.

Objective To study on the influence of comprehensive nursing intervention on extremities function and quality of life (QOL) in community patients with convalescent stroke.Methods A total of 200 community patients with convalescent stroke were selected and randomized into the experimental group and the control group,100 cases each.Patients in the control group were given conventional treatment and following.While patients in the experimental group were given comprehensive nursing intervention besides the treatment mentioned above.Then the therapeutic effects were evaluated by filling out brief Fugl-Meyer assessment(FMA) scale and ADL rating scale(FIM).Life satisfaction index A(LSIA) and quality of life index (QLI) were selected to evaluate QOL.Results After treatment,the scores of LSIA and QLI of the control group showed no difference,but these scores of the experimental group were significantly improved,and was better than those of the control group.In addition,both FMA and FIM in these two groups improved obviously compared to those before treatment and the effect of the experimental group was superior to that of the control group.Conclusions The comprehensive nursing intervention can significantly improve extremities function and ADL and QOL of community patients with convalescent stroke.It is economical,simple and suitable to community families with any education background.

Objective:Reports about impact of lumbar posterolateral fusion on adjacent segment degeneration concentrated on biomechanics and imageology,lack experimental study. This study observes the impact of posterolateral arthrodesis on the adjacent intervertebral disc. To observe the impact of posterolateral arthrodesis on the adjacent intervertebral disc. Methods:Rabbit models of posterolateral arthrodesis were established and the transverse processes of the fourth,fifth and sixth lumbar vertebrae were exposed. Stainless-steel wire0.8 mm in diameter was used to interconnect the three transverse processes in a figure of 8. Methylmethacrylate was then applied to encircle the transverse processes and the wire. Changes in the adjacent disc were observed by light microscopy 3 and 6 months after the operation. Results:Disc degeneration was found at L3-4 at 3 months postoperatively,and further degeneration was noted at this level at 6 months. Conclusion:Posterolateral fusion may accelerate the degeneration of the adjacent intervertebral disc.

Objective To investigate the effects of propranolol on thyroid hormone in patients with hyperthyroidism after operation. Methods Forty patients with mediate or severe degree hyperthyroidism undergoing operation were randomly divided into four groups according to anesthesia and whether to take propranolol in perioperative period: Group A:propranolol plus general anesthesia; Group B: general anesthesia; Group C:propranolol plus cervical plexus blocking; Group D: cervical plexus blocking. The consecutive changes of T 3, T 4,rT 3 and TSH were measured with radioimmunological assay pre and post operatively. Results The level of serum T 3 in all groups decreased 1～7 days after operation. The decrease in serum T 3 leves was most significant 3～7 days after operation in group A and C, 1～3 days after operation in proup B and D(P

Objective To demonstrate the incidence and relative factors of hypothyroidism after partial thyroidectomy (PTC). Methods The records of all euthyroidsm patients who underwent hemithyroidectomy from 1988 to 2000 were reviewed to determine the incidence of postoperative hypothyroidism and the predisposing factors. All the patients age, gender, serum TSH TGA and TPO levels,and the weight of resected thyroid tissue were evaluated. Hypothyroidsm patients were evaluated for the symptoms , timing of diagnosis , and thyroxine therapy. Results Hypothyroidism was diagnosed in 41(3.4%) of 1 210 patients ,inclnding subclinical hypothyroidsm in 28 and overt in 13.The mean postoperative serum TSH level was (9.22?3.36)mU/L. The mean preoperative serum TSH level was (3.14?1.05)mU/L in hypothyroidsm patients but in euthyroid patients was (1.07?0.72)mU/L(P
