Objective:To explore the application of cognitive interview (CI) in intercultural adaptation of the Happiness Scale for Middle-Aged Women (HAS-MW) .Methods:This was a qualitative study. In January 2022, 20 middle-aged women in community of Yanji City were selected by purposive sampling for two rounds of CI, and 10 subjects participated in each round of CI. According to the interview outline, we understood the understanding of the subjects on the HAS-MW items that were preliminarily localized in Chinese. The expert group discussed and revised the items of the scale according to the interview results.Results:In this study, a total of 2 rounds of cognitive interviews were conducted, the age of 10 respondents (P1-P10) in the first round was (49.00±3.55) , and the age of 10 respondents (P11-P20) in the second round was (51.00±3.16) . After the first round, 6 items in HAS-MW were revised due to "imperfect language, grammar and expression". The second round of CI results showed that the respondents understood the contents of the revised scale items and believed that they were consistent with the original scale.Conclusions:Through CI, we can comprehensively understand middle-aged women's understanding of the content of the HAS-MW, effectively find out the cognitive bias caused by improper language expression in the process of the scale's localization, improve the understanding of the content of the scale by the interviewees, which is conducive to intercultural adaptation of the HAS-MW and provides a reference for the revision of the scale.

Objective: To investigate the current situation of cyberbullying and health risk behaviors among secondary vocational school students, to explore the effects of cyberbullying on health risk behaviors, so as to provide a reference for formulating intervention strategies to promote adolescent health related behaviors. Methods: From March to April 2023, a field survey was conducted on 1 184 students from one secondary vocational school each in Jilin City and Yanji City by random cluster sampling method. The data was analyzed using Chi square tests and generalized linear models. Results: Among secondary vocational school students, 839 individuals (70.9%) experienced the cyberbullying, and 1 036 individuals (87.5%) had one and more health risk behavior group. There was a positive correlation between cyberbullying and health risk behaviors ( r=0.60, P <0.01). The generalized linear model analysis showed that female and no Internet addiction were negatively correlated with the health risk behaviors of secondary vocational students ( β =-2.75, -8.90), and the single parent families and peer pressure was positively correlated with the health behaviors of secondary vocational students ( β =2.56, 4.82)( P ＜0.05). Secondary vocational students experienced cyberbullying who from single parent families, peer pressure and social oriented internet usage were more likely to engage in health risk behaviors ( β= 3.41, 4.88, 2.20, P <0.05). Conclusions The incidence of cyberbullying and health risk behaviors among secondary vocational school students is relatively high, and cyberbullying can influence the occurrence of health risk behaviors. It is important to focus on and implement guidance for internet use and health behavior education for secondary vocational students from multiple perspectives, including the family, school, and society. Corresponding intervention strategies should be taken to promote the healthy development of adolescents.

Pyroptosis is a newly discovered programmed cell death that can lead to inflammatory response, its occurrence depends on the sequential activation of inflammatory bodies and caspase, and then the pore-forming generated by the fragmentation of gasdermin D and its cell membrane polymerization. Pyroptosis is mainly comprised of the pathway that depends on caspase-1 activated by flammasomes and the non-classical pathway that depends on caspase-4/5/11 activated by cytoplasmic lipopolysaccharide. As an important mechanism mediating the inflammatory response of the body, pyroptosis plays an irreplaceable role in the body's response to noxious stimuli, which is closely related to many diseases such as nervous system diseases, cardiovascular system diseases and tumors. Recent studies have found that pyroptosis also plays a key role in the occurrence of intestinal ischemia-reperfusion (II/RI). This paper reviews the molecular characteristics, mechanism of pyroptosis and its relationship with II/RI in recent years, in order to provide theoretical basis for the prevention and treatment of II/RI.

Objective:To evaluate the effect of astaxanthin on neuropathic pain in rats and the role of spinal heme oxygenase-1 (HO-1).Methods:Seventy-two SPF-grade healthy adult male Sprague-Dawley rats, weighing 200-250 g, in which intrathecal catheters were successfully implanted, were divided into 6 groups ( n=12 each) by a random number table method: blank control group (group C), sham operation group (Sham group), neuropathic pain (NP) group, NP plus dimethyl sulfoxide (DMSO) group (NP + DMSO group), NP plus astaxanthin group (NP + AST group) and NP plus zinc protoporphyrin plus astaxanthin group (NP+ ZnPP+ AST group). NP was induced by chronic constriction injury in anesthetized rats.In Sham group, the sciatic nerve was only isolated without ligation.At 5 days after establishing the model, 0.5% DMSO 10 μl was intrathecally injected in NP+ DMSO group, astaxanthin 1 μg (dissolved in 10 μl DMSO) was intrathecally injected in NP+ AST group, HO-1 inhibitor zinc protoporphyrin 24 μg (dissolved in 10 μl DMSO) was intrathecally injected, and 3 h later astaxanthin 1 μg (dissolved in 10 μl DMSO) was intrathecally injected in NP+ ZnPP+ AST group.Injection was given once a day for 10 consecutive days in the 3 groups mentioned above.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before establishing the model and 3, 7 and 14 days after establishing the model.The rats were sacrificed at 14 days after establishing the model, and the L 4-6 lumbar segments of the spinal cord were removed for determination of the contents of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), superoxide dismutase (SOD) and glutathione peroxidase (GHS-PX)(by enzyme-linked immunosorbent assay) and expression of HO-1 (by Western blot). Results:Compared with group C and group Sham, the MWT was significantly decreased and TWL was shortened at each time point after establishing the model, the contents of TNF-α and IL-1β were increased, and the expression of HO-1 was up-regulated in the other four groups, the SOD and GSH-PX contents were significantly decreased in NP group, NP+ DMSO group and NP+ ZnPP+ AST group, and the SOD and GSH-PX contents were significantly increased in NP+ AST group ( P<0.05). Compared with NP group, the MWT was significantly increased and TWL was prolonged at 7 and 14 days after establishing the model, the contents of TNF-α and IL-1β were decreased, and the expression of HO-1 was up-regulated in NP+ AST group, the expression of HO-1 was down-regulated in NP+ ZnPP+ AST group ( P<0.05), and no significant change was found in the parameters mentioned above in NP+ DMSO group ( P>0.05). Compared with NP+ AST group, the MWT was significantly decreased and TWL was shortened at 7 and 14 days after establishing the model, the contents of SOD and GSH-PX were decreased, the contents of TNF-α and IL-1β were increased, and the expression of HO-1 was down-regulated in NP+ ZnPP+ AST group ( P<0.05). Conclusion:Astaxanthin can reduce NP in rats, and the mechanism is related to up-regulating the expression of HO-1 in the spinal cord and inhibiting oxidative stress and inflammatory responses.

Objective To study the effect of astragalus polysaccharides combined with hUSCs transplantation on type 2 diabetic rats. Methods Twenty-five SD rats were randomly selected into the normal control group, and the remaining 105 SD rats were used to establish type 2 diabetes model. The 100 rats successfully modeled were randomly divided into the diabetes group, astragalus polysaccharide treatment group, hUSCs treatment group, and astragalus polysaccharide+hUSCs treatment group, with 25 rats in each group. After 2 weeks of treatment, the FBG concentration, insulin and C-peptide concentrations, and body weight changes were measured in each group. The distribution and survival of PKH-26-labeled hUSCs in rat pancreatic tissue were observed by fluorescence microscopy. TUNEL method was used to detect the apoptosis of rat islet cells. Real-time quantitative PCR and Western Blot were used to detect the expression of TGF-β/Smad signaling pathway-related genes in rat pancreatic tissue. Results The FBG concentration of rats in the astragalus polysaccharide treatment group, hUSCs treatment group and astragalus polysaccharide +hUSCs treatment group were significantly decreased, and that in the combination treatment group was significantly lower those in the astragalus polysaccharide group and hUSCs group, and the differences were statistically significant ( all P<0 . 05 ) . Compared with the diabetic group , the insulin concentration, C-peptide concentration and body weight in the astragalus polysaccharide treatment group, hUSCs treatment group and combination treatment group rats were significantly increased, and those in the combination treatment group was significantly higher than those in the astragalus polysaccharide treatment group and in the hUSCs treatment group, the differences were statistically significant( all P<0.05). The results of fluorescence microscopy showed that the number of PKH-26 positive hUSCs in the combined treatment group was 74.64 ±9.75 in each high power field, which was significantly higher than that in the hUSCs treatment group (43.64±5.83), the difference was statistically significant (P<0.05). Compared with the diabetic group, the apoptotic rates of islet cells in the astragalus polysaccharide treatment group and the hUSCs treatment group were reduced, and the relative expressions levels of mRNA and protein of TGF-β1, Smad3, and Smad7 in the pancreatic tissue were also significantly reduced(all P<0.05). The reduction was more significant in the combination treatment group, and the differences were statistically significant (all P<0.05). Conclusions Astragalus polysaccharide combined with hUSCs transplantation can effectively reduce the FBG concentration, increase the concentration of insulin, C-peptide and body weight, reduce the apoptosis of pancreatic islet tissue, which may be related to the reduction of TGF-β/Smad in pancreatic tissue. Signaling pathways are involved in suppressing the inflammatory response.

Objective To explore the clinicopathological characteristics,diagnosis,treatment and prognosis of accessory breast cancer.Methods Clinical and pathological data of 37 accessory breast cancer patients from Dec 2005 to Aug 2017 were reviewed.Results 12 patients underwent breast-conserving local wide excision plus axillary lymph node dissection.5 cases were treated by segmental resection and 19 patients by Auchincloss or Halsted mastectomy;One patient abandoned surgery.The most common histological type of accessory breast cancer was infiltrating ductal carcinoma (26 cases,70.3％) followed by adenocarcinoma (4 cases) and miscellaneous type (7 cases).The most common AJCC pathological stages were stage Ⅱ (n =24,65 ％),Ⅰ (n =8),Ⅲ(n =3) and Ⅳ (n =2).The median follow-up time was 6 (1-12) years,the followup rate was 100％.Until Dec 2017,7 patients died from metastasis and the others were alive.Conclusions Accessory breast cancer is rare and with poor prognosis.The diagnosis depends on clinical manifestations,imaging and pathology.Surgery is the mainstay therapy,adjuvant chemo therapy is recommanded.

? Concept analysis of expectation regarding aging (ERA) is carried out by Walker and Avant's strategy. Four defining attributes of ERA were identified including self-definition and social attributes, aging perception, degree of positive willingness to participate in the life process, confidence in adapting to the decline with aging. ERA mainly affects the health outcomes of the elderly through health promotion behaviors, activities of daily living, physical examination behaviors, the path of new-established support system,expectation regarding aging and attitudes towards aging of stakeholders.

Objective:To investigate the association between indoleamine 2,3-dioxygenase(IDO)expression in tumor tissue,its periph-eral blood activity, and the efficacy of neoadjuvant chemotherapyin patients with breast cancer. Methods: Immunohistochemistry (IHC)and high-performance liquid chromatography(HPLC)were used to measure IDO protein expression in tumor tissue,and kynuren-ine(Kyn),tryptophan(Trp),and IDO activity(Kyn/Trp)in peripheral blood before neoadjuvant chemotherapy in 53 patients with breast cancer from Tianjin Medical University Cancer Institute and Hospital between September 2015 and December 2016.The correlations between the expression and activity of IDO and the efficacy of chemotherapy were analyzed.Results:In tumor tissue,IDO expression-before neoadjuvant chemotherapy was related to clinical tumor stages(P=0.006),node stages(P=0.020),clinical stages(P=0.045),and estrogen receptor(ER)status(P=0.014).High IDO activity before neoadjuvant chemotherapy in peripheral blood was associated with high IDO expression in tumor tissue(P=0.004),and was also correlated with clinical tumor stages(P=0.019)and node stages(P=0.047). Univariate analysis showed that the clinical efficacy of neoadjuvant chemotherapy was associated with pre-chemotherapeutic clinical tumor stages(P=0.049),ER status(P=0.025),and molecular subtype(P=0.014),while pathologic complete response(pCR)was related to pre-chemotherapeutic clinical tumor stages(P=0.014).Importantly,the clinical efficacy of neoadjuvant chemotherapy and pCR were both related to IDO expression and activity before chemotherapy(all P<0.05).Multivariate analysis showed that pre-chemotherapeu-tic IDO activity in peripheral blood was the only independent factor that affected pCR(P=0.032).Conclusions:Tumor tissue IDO expres-sion and peripheral blood IDO activity before chemotherapy were associated with chemotherapy efficacy,and could provide promising information for the clinical prediction of chemotherapy sensitivity.

The operating room is the main place of surgery,but there exist many ethical problems when developing quality nursing service in operating rooms.These problems mainly related to the imperfect preoperative and postoperative visit systems,the lack of effective communication and protection of patients privacy during the operations,and the lack of self-discipline spirit.To solve these problems,we should improve the preoperative and postoperative visit system,strengthen the psychological counseling for patients,cultivate the nurses' self-discipline spirit,respect and protect the privacy of patients,so as to improve the quality of nursing service in the operation rooms,and better service for patients.

Objective To explore the change of peripheral galectin (Gal)-3 and N-terminal B-type brain natriuretic peptide (NT-proBNP) in patients with chronic heart failure.Methods A total of 89 patients with chronic heart failure (CHF) were enrolled.Peripheral Gal-3,NT-proBNP were detected by enzyme-linked immunosorbent assay (ELISA) or Electrochemical luminescence method.The expression levels of Gal-3,NT-proBNP in patients with different kinds of heart failure and cardiac functional grading were analyzed.Results There were significant differences in expression levels of Gal-3 and NT-proBNP between patients with HFPEF and patients with HFREF.There was significant differences of Gal-3 and NT-proBNP in patients with NYHA heart function class Ⅱ,Ⅲ and Ⅳ.Gal3 was positively correlated with NT-proBNP (r =0.230,P =0.030) and negatively correlated with LVEF (r =-0.533,P =0.000).NT-proBNP was negatively correlated with LVEF (r =-0.372,P =0.000).Conclusion Peripheral Gal-3,NT-proBNP could be considered as two important markers for judging severity of illness in patients with CHF.
