Objective: To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents. Methods: Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents. Results: The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01). Conclusions Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

Objective To investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

Coronary heart disease （CHD） with atherosclerosis is a common chronic disease worldwide， and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang （CLMT）， first mentioned in the Shang Han Lun （《伤寒论》）， is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit， with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways， including regulating related signaling pathways， inhibiting the expression of inflammatory factors， improving oxidative stress damage， modulating neurotransmitter levels， suppressing the hypothalamic-pituitary-adrenal axis， promoting mobilization of mesenchymal stem cells from the bone marrow， and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression， effectively reduces negative emotions， improves traditional Chinese medicine （TCM） syndrome scores， and decreases levels of inflammatory factors. Furthermore， it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， PubMed， and other databases in the past 15 years， in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.

AIM: To explore the role and mechanism of silent mating type information regulator 2 homolog 3 (SIRT3) in attenuation of intestinal ischemia-reperfusion (I/R) injury by dexmedetomidine in mice. METHODS: Twenty-four healthy male C57BL mice were divided into 4 groups randomly (n=6): sham operation group (Sham group), intestinal ischemia-reperfusion group (I/R group), dexmedetomidine group (Dex group), SIRT3 inhibitor 3-TYP group (3-TYP group). Superior mesenteric artery was clamped for 45 min followed by reperfusion for 2 h to establish intestinal I/R model in I/R group, Dex group, and 3-TYP group. Sham group received sole sham operation. 1 h prior to onset of ischemia, 3-TYP was injected into mice in 3-TYP group intraperitoneally (5 mg/kg, diluted to 0.3 mL), and 0.3 mL normal saline into mice in Dex group intraperitoneally. 30 min prior to onset of ischemia, dexmedetomidine was injected into mice in 3-TYP group and Dex group intraperitoneally (25 μg/kg, diluted to 0.3 mL). 1 h and 30 min prior to onset of ischemia, 0.3 mL normal saline was injected into mice in Sham group and I/R group intraperitoneally, respectively. 2 h of after reperfusion, the mice were sacrificed under anesthesia. Intestinal tissues were took and observed for pathological changes under light microscope after HE staining, and the injury was assessed via the Chiu's score method, and activities of SIRT3 and superoxide dismutase 2 (SOD2) were detected via spectrophotometry, and malondialdehyde (MDA) via spectrophotometry. RESULTS: The pathological injury was exacerbated, and the Chiu's score, the MDA level elevated remarkably, while the activity level of SIRT3 and SOD2 declined remarkably in I/R group, Dex group and 3-TYP group compared to Sham group (P<0.05). The pathological injury was alleviated, and the Chiu's score declined remarkably in Dex group and 3-TYP group compared to I/R group (P<0.05); and the MDA level declined remarkably, while activity level of SIRT3 and SOD2 elevated remarkably in Dex group compared to I/R group (P<0.05); and there was no significant difference both in the activity level of SIRT3 and SOD2 and in the MDA level between 3-TYP group and I/R group. The pathological injury was exacerbated, and the Chiu's score, the MDA level elevated remarkably, while the activity level of SIRT3 and SOD2 declined remarkably in 3-TYP group compared to Dex group (P<0.05). CONCLUSION: SIRT3 and its downstream SOD2 are involved in mediating the effect of attenuation of intestinal ischemia-reperfusion injury through inhibiting oxidative stress response by dexmedetomidine.

Objective? To explore the effects of symposium involving patients and their family members on health education in patients with acute myocardial infarction after percutaneous transluminal coronary intervention (PCI). Methods? Totally 86 patients with acute myocardial infarction receiving PCI in Ningbo First Hospital from January 2017 to June 2018 were selected continuously and divided into the control group (n=43) and the observation group (n=43). Patients in the control group received conventional health education which combined oral education and education manuals, while patients in the observation group symposium-based health education which involved both patients and their family members on the basis of conventional education after PCI. Both groups received health education for 4 weeks. Health knowledge about acute myocardial infarction, rehabilitation initiative, postoperative complication and satisfaction with overall nursing were compared between the two groups before and after intervention. Results? The health-related knowledge of the patients with acute myocardial infarction in the observation group 4 weeks after intervention scored (94.3±4.0), higher than that of the control group, which was (78.4±5.1), and there was statistically significant difference (t=8.285, P＜ 0.05). The scores of five dimensions of rehabilitation initiative (coordination with therapy, compliance, needs for rehabilitation, emotions post frustration and encouragement from family members and nurses) of the observation group were higher than those of the control group (t=4.726, 5.114, 3.975, 7.116, 5.893; P＜0.05). The incidence rate of postoperative complication in the observation group was 9.30%, lower than that of the control group, which was 30.23%, and there was statistically significant difference (χ2=5.939, P＜0.05). The nursing satisfaction of the observation group was 96.73%, higher than that of the control group, which was 83.78%, and there was statistically significant difference (χ2=4.904, P＜0.05). Conclusions? The symposium involving patients and their family members for patients with acute myocardial infarction after PCI can improve the patients' disease-related knowledge, satisfaction with overall nursing and rehabilitation initiative, and reduce the postoperative complications effectively.

Objective To evaluate narrow?band imaging(NBI)for early esophageal cancer and pre?cancerous lesions. Methods A total of 170 patients ( 192 lesions) diagnosed as having superficial esophageal carcinoma and precancerous lesions by endoscopy were retrospectively analyzed. Clinical data of endoscopy, narrow?band imaging (NBI) and iodine chromoscopy were analyzed.Results The detection rates of early esophageal cancer were both 100?? 0% in NBI(13/ 13) and iodine staining (13/ 13), with no statisti?cally significant difference (P>0?? 05).The detection rate of high grade intraepithelial neoplasia in NBI and i?odine staining was 94?? 9% (94/ 99) and 100?? 0% (99/ 99) respectively with no statistically significant differ?ence (P>0?? 05); The detection rate of low grade intraepithelial neoplasia in iodine staining was 100?? 0%(80/ 80), significantly higher than that of NBI 78?? 8% (63/ 80) (P<0?? 01).Conclusion NBI and iodine staining endoscopy show better diagnostic value for early esophageal cancer and similar diagnostic value for high grade intraepithelial neoplasia in precancerous lesions. But for the low grade intraepithelial neoplasia, the diagnostic value of iodine staining endoscopy is better than that of NBI.

Objective To evaluate the effectiveness and safety of a transanal drainage tube(TDT) for decompression of acute left-sided obstruction of colorectum.Methods Fifty-seven patients with acute left-sided colorectal obstruction were enrolled in this study from January 2010 to December 2014.The obstruction location, property, success rate of insertion, one-procedure rate and complication rate were analyzed.Results There were 53 cases of primary colorectal cancer,among which lesions were located in the transverse colon in 1 case, in descending colon in 10, in sigmoid colon in 24,and in rectum in 18.There were 4other cases, one sigmoid colonic metastases of pulmonary cancer, 1 adhesive colonic obstruction after ovary surgery, 1 cervical cancer involved with rectum with stricture and obstruction, and 1 descending colonic obstruction caused by Crohn's Disease.TDT was successfully inserted in 55 cases(96.5％) without complications,in which 43 cases of primary colorectal cancer finally underwent surgery.TDT indwelled from 0 to 22days, for an average of (8.7± 4.4)d.Hartmann operation was performed in 9 patients,6 of which underwent sufficient lymphnode dissection.Among the 43 patients, one-stage operation was performed in 34 (79.1％),of which 30 cases underwent sufficient lymph node dissection, without stoma leakage.And the rest of 13 cases refused surgery because of poor prognosis and financial problems.One patient with Crohn's Disease refused surgery after TDT insertion and was discharged after palliation of distention.Conclusion TDT is safe and effective in decompressing acute left-sided benign obstruction with high success rate and low expenditure, and can achieve preoperative colonic lavage in one-stage operation for acute left-sided colorectal malignant obstruction.

Objective To investigate the characteristics of pathogen distribution and drug resistance of pulmonary infection in hemorrhagic brain injury patients from neurosurgical intensive care unit (NICU).Methods Clinical data of 234 patients with hemorrhagic brain injury hospitalized in NICU from March 2013 to September 2014 were retrospectively analyzed.According to the incidence of pulmonary infection,the patients were divided into pulmonary infection group and non-pulmonary infection group.Parameters estimated were admission GCS,sex,age,history of smoking,time of coma,duration of mechanical ventilation,NICU length of stay.Patients in pulmonary infection group were analyzed on the distribution of pathogens and incidence of drug resistance.Results A total of 158 patients (67.5％) had pulmonary infection.Among them 60 cases (38.6％) were found to be co-infected including infection with two pathogens in 26 cases (16.5％),three pathogens in 19 cases (12.0％),and four and more pathogens in 16 cases (10.1％).Age and smoking increased the incidence of pulmonary infection (P ＜ 0.05).Time of coma,duration of mechanical ventilation,and NICU length of stay were prolonged in pulmonary infection group than in non-pulmonary infection group (P ＜ 0.05).A total of 219 strains of pathogens were isolated from the patients in pulmonary infection group.Specifically,there were 193 strains of gram negative bacteria (88.1％),13 strains of gram positive bacteria (5.9％),and 13 strains of fungi (5.9％).Gram negative were sensitive to amikacin,imipenem,cefoperazone/ sulbactam and ciprofloxacin.Staphylococcus aureus isolated were 100％ sensitive to vancomycin,linezolid and teicoplanin,and were completely penicillin resistant.Fungi were not resistant to voriconazole,itraconazole,ketoconazole,fluconazol,and amphotericin B.Conclusions High incidence of pulmonary infection is noted among the hemorrhagic brain injury patients in NICU,and the pathogens are diverse dominated by Gram negative bacteria.Incidence of multi-drug resistant pulmonary infection is high,indicating that the key point is to choose antibiotics rationally based on drug sensitivity test.

Objective To explore the establishment of the coherent health service system for patients undergoing surgery in this region to optimize health care resources.Methods Using the Quantitative-qualitative research to investigate the conditions and needs of the regional network of health service between the third-grade class-A hospital and its collaborative hospitals,and it is about two-way referral,the follow ups after discharge,remote consultation,the conditions and needs of the remote training and the knowledge to the obstacles of carrying out the regional network service.Results The doctors and nurses in the research said,it was difficult to achieve the up referral in two-way referral,and there was financing obstacles for remote consultation and training,furthermore,the effects of the remote training was uncertain.Conclusions The regional network of health service between the third-grade class-A hospital and its collaborative hospitals is still weak,and we need to intensify the development of the regional network service.

Objective To investigate the relationship between antipituitary antibodies (APAs) and hypopituiarism following traumatic brain injury (TBI),as well as the severity of brain injury.Methods The study included 73 patients who suffered TBI 9 to 12 months ago and were diagnosed with hypopituitarism during the follow-up.Based on their Glasgow Coma Scale (GCS) on admission they were categorized into three groups:A (3-8),B (9-12) and C (13-15).Levels of plasma pituitary hormones (GH,TT,FT3 and FSH/LH) and APAs were measured in all patients with chemiluminescence assays and ELISA,respectively.Results Patients in group A had higher levels of APAs and lower levels of hormones compared with those in group B(P＜0.001) or group C(P＜0.001),while no significant difference was found between group B and group C for levels of either APAs (P＞0.05) or hormones (P＞0.05).Levels of APAs were negatively correlated with both GH (r=-0.64071,P＜0.001) and GCS (r=-0.50132,P＜0.001).Conclusion The present investigation provides preliminary evidence that APAs may be associated with the development of TBI-induced hypopituiarism.It suggests that the severity of hypopituiarism following TBI could be predicted by measuring the level of APAs.
