Objective To study the clinical value of extensively whey protein hydrolyzed formula and partially whey protein hydrolyzed formula as an adjunctive therapy in treating infantile eczema.Methods Totally 59 bottle-feeding babies with infantile eczema were divided into three groups depending on different formula feeding:extensively hydrolyzed formula feeding group (eHF group,n =18),partially hydrolyzed formula feeding group (pHF group,n =22),and conventional cow's milk formula feeding group (CMF group,n =19).Meanwhile,all patients received the same drug treatment.The effective rate and remission rate were evaluated using the SCORing Atopic Dermatitis (SCORAD) index.Results After 2 weeks of treatment,the effective rate was 38.9％ and the remission rate was 50.0％ in the eHF group,which were significantly different from those in the CMF group (5.3％ and 31.6％) (x2 =12.225,P =0.002).The effective rate was 9.1％ and the remission rate was 40.9％ in the pHF group,showing no significant difference when compared with the CMF group (x2 =0.761,P =0.683).After 8 weeks of treatment,the effective rate was 55.6％ and the remission rate was 38.9％ in the eHF group,comparing to 15.8％ and 47.4％ in the CMF group,the difference was statistically significant (x2 =8.498,P =0.014).The effective rate was 31.8 ％ and the remission rate was 59.1％ in the pHF group,a trend towards higher than that of the CMF group,but the difference was not statistically significant (x2 =4.912,P =0.086).Before (F =0.773,P =0.466) and after (F =1.313,P =0.277) the treatment,the growth and development data in different groups showed no significance differences.Conclusion Both the extensively and partially whey protein hydrolyzed formula play an adjunctive role in treating infantile eczema,although the treatment effectiveness of the extensively hydrolyzed formula appears earlier than that of the partially hydrolyzed formula.

Objective To explore the effect of clinical nursing pathway(CNP)on allergic rhinitis in patients with subcutaneous immunotherapy.Methods One hundred and twenty patients with allergic rhinitis treated with subcutaneous immunotherapy were equally randomized into the observation group and the control group.The former group were managed with clinical nursing pathway and the latter received only routine nursing care.The curative effect of subcutaneous immunotherapy was compared between the two groups including local adverse reactions,treatment compliance,patients' satisfaction and quality of life.Results The scores by symptom assessment at time points of half a year,years 1,2 and 3 showed the symptoms at different time points between the groups were significantly different by the comparison between time and the interactive effect of main effect(F=678.24,P<0.01),and the symptoms in the two groups were both alleviated with the extension of treatment due to the compared time effect at F=47.16, P<0.01.The scores on the symptoms in the observation group were significantly lower than those of the control group at different time points(P<0.01).The experiment group was better than the control group in terms of local adverse reactions,treatment compliance, quality of life and patient's satisfaction(P<0.01)Conclusion Clinical nursing pathway can improve patient's compliance,improve immunotherapy,reduce adverse reactions and improve the quality of life of patients as well as patients' satisfaction.

Objective To investigate the angiogenesis effects of Salvia miltiorrhiza in heterotopically grafted frozen-thawed mouse ovaries. Methods The ovaries thawed after cryopreservation were xenografted into the donated kidney capsules of 8- to 12-week adult male mice. The mice were divided into two groups, saline and Salvia miltiorrhiza groups, the mice either in the saline or in Salvia miltiorrhiza groups were administered I.p. Daily either saline(0.5ml) or Salvia miltiorrhiza(0.5g)respectively, from the day prior transplantation. The two groups were sacrificed 1 day,2 days and 7 days after transplantation respectively, the grafts from thawed,1 day,2 days,7 days were removed for follicle counting, immunohistochemical studying and detecting of the mRNA expression of vascular endothelial growth factor(VEGF). Results The number of follicles and survival rates in grafts after transplantation of Salvia miltiorrhiza group were more than that of saline group (P<0.05);the expression of VEGF increased after transplantation,peaked on day 7,there was no difference between the two groups (P>0.05);the apoptosis index of Salvia miltiorrhiza group was less than that of saline group (P<0.05), the mRNA expression of VEGF188 and VEGF164 of Salvia miltiorrhiza group was more than that of saline group on 48 hours after transplantation(P<0.05). Conclusion Salvia miltiorrhiza may provide benefits for folliculogensis and decreasing the apoptosis index of follicles. Nevertheless,a increase in the VEGF188 and VEGF164 isoform in the Salvia miltiorrhiza group may suggest the positive effect of exogenous Salvia miltiorrhiza therapy in the early stage of angiogenesis.

Objective: To examine the influencing factors of the efficiency of county-level centers for disease control and prevention ( CDCs) in China. Methods:458 county-level CDCs were selected based on a systematic sam-pling method. Multilevel modeling was used to analyze the region-level and institution-level influencing factors affect-ing the efficiency of CDCs. Results: It was found that the region ( province) is associated with the efficiency of a CDC. The region-level factor of population density exhibited a significant influence, while the institution-level factors such as the proportion of health technicians, service income and CDC laboratories per capita also had an influence on overall efficiency. Conclusions: Both the region-level and institution-level determinants influence efficiency. Multi-level modeling can help researchers gain a comprehensive understanding of the influencing factors that affect the CDC efficiency.

Objective:To evaluate the efficacy and safety of lactulose combined with polyethylene glycol for bowel preparation before colonoscopy in patients of different risks.Methods:A total of 208 patients undergoing colonoscopy were enrolled, including 108 high-risk and 100 low-risk patients. The high-risk patients were divided into group A (54 taking lactulose + polyethylene glycol) and group B (54 taking polyethylene glycol), and the low-risk patients were divided into group C (49 taking lactulose + polyethylene glycol) and group D (51 taking polyethylene glycol). The Boston bowel preparation score, cecal intubation time, withdrawal time, the detection rate of colonic polyps and adenoma, and the incidence of adverse reactions were observed.Results:Among the high-risk patients, the Boston bowel preparation score and adenoma detection rate in group A [(6.35±1.15) scores, 46.3%] were significantly higher than those in group B [(5.76±0.89) scores, 22.2%, both P<0.05], and the first defecation interval in group A was significantly shorter than that in group B [(1.20±0.85) h VS (3.29 ± 2.93) h, P<0.05]. There was no significant difference in adequate bowel preparation rate, polyp detection rate, frequency of defecation or incidence of adverse reactions between group A and B. In the low-risk patients, the first defecation interval in group C was significantly shorter than that in group D [(1.65 ± 1.35) h VS (3.42 ± 2.64) h, P<0.05], and the incidence of adverse reactions was significantly lower than that in group D (44.9% VS 64.7%, P<0.05). There was no significant difference in adequate bowel preparation rate, Boston bowel preparation score, adenoma detection rate, polyp detection rate or frequency of defecation between group C and D. Conclusion:For the high-risk patients, the effect of lactulose combined with polyethylene glycol for bowel cleansing is better than that of traditional polyethylene glycol in the improvement of the Boston bowel preparation score, adenoma detection rate, and the first defecation interval. For low-risk patients, lactulose combined with polyethylene glycol regimen has few advantages over traditional polyethylene glycol regimen.

Objective:To explore the effectiveness of the Shewhart control chart-based assessment and early warning system in prevention of medical device-related pressure injury(MDRPI).Methods:152 critically ill patients admitted to Hebei Central Hospital from January 2020 to December 2021 were selected and divided into a control group and an observation group based on different methods of assessing MDRPI risk,with 76 cases in each group.The control group adopted the Braden scale to assess the risk of MDRPI.The observation group adopted a safety early warning system based on Shewhart control charts to assess the risk of MDRPI in patients.Nursing measures were undertaken according to MDRPI risk grade in both groups.The occurrence of adverse events of MDRPI,nursing safety quality and nursing comprehensive quality were compared between the two groups.Results:The incidence rate of head,neck and face adverse events of MDRPI and the total incidence of adverse events of MDRPI of the patients in the observation group were lower than those in the control group(x2=4.802,5.758,P<0.05).The safety quality and comprehensive quality of nursing of 20 nurses in the observation group were higher than those in the control group(t=6.654,7.172,P<0.05).Conclusion:The application of assessment and early warning system based on Shewhart control chart in clinical nursing management can effectively reduce the incidence of MDRPI adverse events and improve the quality of nursing safety and comprehensive nursing.

Objective:To explore the mediating effects of self-control and rumination between neuroticism and insomnia in college students.Methods:A cross-sectional survey was conducted among 767 college students from a university in Sichuan province with Chinese big five personality inventory-15, insomnia severity index, ruminative responses scale, and self-control scale.Results:The prevalence of insomnia was 36.6% among college students.The scores of neuroticism (9.63±3.41), rumination (22.27±5.44) and ISI (6.61±4.28) were positively correlated with each other ( r=0.281-0.389, P<0.01), while each of them was negatively correlated ( r=-0.453--0.194, all P<0.01) with self-control (60.71±9.41). Analysis of mediating effects revealed that neuroticism not only directly affected insomnia, but also indirectly affected insomnia through the mediating effects of rumination and self-control respectively. Conclusion:Self-control and rumination have mediating effects between neuroticism and insomnia in college students.

This study aimed to explore the role of miR-130a-3p in cardiomyocyte hypertrophy and its underlying mechanisms. Pressure-overload induced myocardial hypertrophy mice model was constructed by thoracic aortic constriction (TAC). , norepinephrine (NE) was used to stimulate neonatal rat cardiomyocytes (NRCMs) and H9c2 rat cardiomyocytes to induce hypertrophic phenotypes. The expression of miR-130a-3p was detected in mice hypertrophic myocardium, hypertrophic NRCMs and H9c2 cells. The mimics and inhibitors of miR-130a-3p were transfected into H9c2 cells to observe the role of miR-130a-3p on the hypertrophic phenotype change of cardiomyocytes separately. Furthermore, whether miR-130a-3p regulated hypertrophic related signaling pathways was explored. The results showed that the expression of miR-130a-3p was significantly decreased in hypertrophic myocardium, hypertrophic NRCMs and H9c2 cells. After transfection of miR-130a-3p mimics, the expression of hypertrophic marker genes, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and β-myosin heavy chain (β-MHC), and the cell surface area were notably down-regulated compared with the control group (mimics N.C. + NE group). But after transfection of miR-130a-3p inhibitor, the expression of ANP, BNP and β-MHC in H9c2 cells increased significantly, and the cell area increased further. By Western blot, it was found that the protein phosphorylation level of Akt and mTOR were down-regulated after over-expression of miR-130a-3p. These results suggest that miR-130a-3p mimics may alleviate the degree of cardiomyocyte hypertrophy, meanwhile its inhibitor can further aggravate cardiomyocyte hypertrophy. Over-expression of miR-130a-3p may attenuate cardiomyocytes hypertrophy by affecting the Akt pathway.
