Objective To observe the efficacy of multifactor intensive nursing intervention on chronic heart failure patients with outside hospital treatment,including self-management ability and related clinical indicators.Methods By application of prospective study,a total of 215 patients with chronic heart failure discharged from hospital were randomized into the usual care group (105 cases) and the intensive nursing intervention group (1 10 cases).Patients were followed up for 12 months,and 205 patients completed the follow-up.The usual care group only received conventional outpatient follow-up,the intensive intervention group patients received telephone counseling,more detailed clinical follow-up and regular health education.The intervention effect was compared between two groups.Results Compared with the usual care group,the passing rate of sodium/water limit and daily monitoring of weight was higher in the intensive intervention group.Left ventricular ejection fraction and six-minute walking test were better in the intensive intervention group,while the level of NT-pro-BNP was lower in the intensive intervention group.Compared with the usual care group,re-hospitalization rate and incidence of cardiovascular events were lower in the intensive intervention group.Conclusions Multifactor intensive nursing intervention is helpful on improving self-management ability,alleviate cardiac function,reduce re-hospitalization rate and incidence of cardiovascular events for chronic heart failure patients.

A data-based quantitative study was conducted by examining 43 bilingual package inserts of Chinese medicine. The results indicated that most inserts were poorly constructed with incomplete formats. Furthermore, there seemed no standardized translationforthe section titles, and some of them were even translated incorrectly. It was suggested that insert translation should follow the “reader-centered principle” which was determined by its communicative purpose. Translators should take full advantage of intertextual reference and construct complete and standard insert formats of Chinese medicine, thus helping readers obtain information more quickly and easily. This paper intends to advance some suggestions concerning the text constructionof bilingual package inserts of Chinese medicineand help enterprises in this line increase their competitiveness in the international market.

Objective To investigate the effect of continued nursing on postoperative outcomes of discharged patients with chronic suppurative otitis media.Methods Toally 198 discharged patients were randomized into the control group (n=98) and the observation group (n=100).The patients in both groups received normal health education and additionally the continued nursing was used in the observation group for health education by way of phone call follow-up,on-the-spot consultation and QQ consultation.The mastery of related knowledge and skills,incidence of secondary tympanic membrane and readmission rate were compared.Results Six months after discharge,the observation group was significantly better than those the control group in the mastery of related knowledge and skills (P＜0.05).The incidence of secondary tympanic membrane perforation was not statistically significant between the groups(P＞ 0.05).The readmission rate at the second week and the third week between the two groups had no statistically significant difference (P＞ 0.05).However,the readmission rate at the first,second,third and sixth month were statistically different (P＜0.05).Conclusion Continued nursing to the postoperative discharged patients with chronic suppurative otitis media can improve the follow-up rate after discharge and self-nursing capacity,and as a result promote their recovery.

Objective To establish the platelet antigen panel cells and to apply them in the detection and identification of platelet alloantibody.Methods Human platelet antigen(HPA)1-16 genotyping from 1 500 un-related blood donors in Nanning area were performed by the polymerase chain reaction-sequence specific primers(PCR-SSP)technique,platelet antigen cells with O blood type were chosen to establish the panel cells of platelet antigen.The phenotype of the panel cells were verified by the reference sera from the 14th platelet immunology workshop of the International Society of Blood Transfusion(ISBT).And then these panel cells were used in clinic to detect the platelet alloantibody and the samples from the 14th and 15th platelet immunology workshop of ISBT.Re-sults Six platelet cells with consistent phenotype and genotypes and covering the HPA 1-5 and 1 5 systems were selected to estab-lish the platelet panel cells and successfully applied them in the clinical and scientific sample detection and identification.Conclusion Platelet antigen panel cells are established successfully,which provides the experimental basis for the diagnosis and research of platelet allogenic abnormal immunity diseases.

Objective To investigate the effect of Goserelin in protection of the ovarian function of pre-menopausal breast cancer patients. Methods Eighty premenopausal patients with breast cancer randomly divided equally into study group and control group. The two groups were compared in terms of the menstrual status and the levels of E2,FSH,LH before and after chemotherapy. Results The menstrual recovery rates of the study group and the control group were 90% and 57.5%,respectively ,with statistically significant difference between them (P = 0.018). In the study group,the serum E2 decreased gradually to the postmenopausal level,and the serum levels of FSH and LH were also significantly decreased during the treatment. While in the control group ,the E2 levels gradually decreased ,but the levels of FSH and LH significantly increased during the chemotherapy. Conclusions Goserelin can effectively prevent the injury of ovarian function caused by chemotherapy.

Objective To achieve arabinose-controlled expression of HtrA strain and detect the expression of HtrA protein.Methods Arabinose promoter with htrA100 was amplified from pACD-htrA vector by PCR and cloned into pGP704 vector.Then, Shigella flexneri 2a strain 301 was transferred with the recombinant plasmid pGD-htrA and an AraC-expression vector .The expressions of HtrA in whole-cell and periplasmic space were detected by Western blotting .Results The suicide plasmid-mediated homologous recombinant vector and the inducible HtrA expression strain were successfully constructed.Without arabinose,HtrA protein was hardly detected ,but in the presense of arabinose , HtrA protein could be detected in whole-cell lysate and in periplasmic space lysate by Western blot .Conclusion Homologous recombination using suicide plasmid can significantly knock down the expression of HtrA protein .After being induced with arabinose , HtrA protein can be expressed normally .

Objective To observe the expression of the polysialic acid neural cell adhesion molecule ( PSA-NCAM) in the hippocampus of rats after exposure to low intensity ( 16 Hz,90 dB) infrasound for different periods.Methods One hundred and twenty male Sprague-Dawley rats were randomly divided into infrasound exposure and normal groups.The exposure group was tjem further divided into 1 day,7 days,14 days and 21 days exposure groups.After exposure,the rats' brains were removed and an immunohistochemical technique was used to observe the expression of PSA-NCAM in the hippocampus after 1,7,14 or 21 days of exposure. Methods The expression of PSA-NCAM had increased significantly after exposure for 7 days. It peaked at 14 days,then had decreased by 21 days,but always remaining higher than in the normal group.After the infrasound exposure had ended,the expression of PSA-NCAM demonstrated a tendency of decrease over time,and the least was on the 21st day.The largest decrease was observed in the 14 days exposure groups. Conclusion 16 Hz,90 dB infrasound can increase the expression of PSA-NCAM in the hippocampus,at least in rats.This suggests that low intensity infrasound might initiate recovery of an injured central nervous system.Migration of neural stem cells may aid in the repair of neural injuries resulted from infrasound exposure.

BackgroundMobile phone addiction has attracted widespread attention in society， and psychological abuse and neglect is an important factor in predicting mobile phone addiction， whereas limited research has been done to evaluate its impact on mobile phone addiction. ObjectiveTo explore the correlation of psychological abuse and neglect with mobile phone addiction， and to test the pathway of self-esteem and interpersonal alienation， so as to provide references for preventing and curbing mobile phone addiction in junior high school students. MethodsIn May 2022， a cluster sampling was utilized to select 800 students in two middle schools in a county of Hainan Province， and all students were assessed using Child Psychological Abuse and Neglect Scale （CPANS）， Mobile Phone Addiction Index （MPAI）， Rosenberg Self-esteem Scale （SES） and Interpersonal Alienation Scale of Adolescent StudentsAlienation Scale. Pearson correlation analysis was adopted to determine the correlation among the above-mentioned scales， and Process Macro 3.5 for SPSS was used to test the mediation effect. ResultsCPANS score was negatively correlated with SES score （r=-0.278， P<0.01）， and positively correlated with Interpersonal Alienation Scale score and MPAI score （r=0.471， 0.372， P<0.01）. SES score was negatively correlated with Interpersonal Alienation Scale score and MPAI score （r=-0.438， -0.196， P<0.01）. Interpersonal Alienation Scale score was positively correlated with MPAI score （r=0.392， P<0.01）. Interpersonal alienation （indirect effect value was 0.104） played a mediation role in the relationship between psychological abuse and neglect and mobile phone addiction. Self-esteem and interpersonal alienation exhibited a chained mediation effect on the relationship between psychological abuse and neglect and mobile phone addiction （indirect effect value was 0.026）， accounting for 6.99% of the total effect. ConclusionPsychological abuse and neglect can not only directly predict mobile phone addiction， but also can indirectly affect mobile phone addiction through separate mediation of interpersonal alienation or chained mediation of self-esteem and interpersonal alienation. ［Funded by High-level Talent Project of Hainan Natural Science Foundation （number， 721RC511）］
