Objective:To explore the impact of self-disclosure on demoralization syndrome in patients with permanent enterostomy for colorectal cancer, so as to provide reference for clinical nursing interventions for those patients.Methods:From January to May 2023, convenience sampling was used to select 207 patients with permanent enterostomy for colocrctal cancer of the Wound Ostomy Clinic of Laoshan Campus of the Affiliated Hospital of Qingdao University as the research subjects. A survey was conducted on patients using the General Information Questionnaire, Distress Disclosure Index, Social Support Rating Scale, and the Demoralization Scale Mandarin Version.Results:Among 207 patients with permanent enterostomy for colorectal cancer, the scores of self-disclosure, social support, and demoralization syndrome were 35.00 (26.00, 47.00) , 32.00 (26.00, 39.00) , and 35.00 (23.00, 47.00) , respectively. A total of 128 patients (61.8%) were in moderate demoralization, and 37 patients (17.9%) were in severe demoralization. Multiple linear regression analysis showed that place of residence, self-care of stoma, self-disclosure, and social support were the influencing factors for demoralization syndrome in patients with permanent enterostomy for colorectal cancer ( P<0.05) . Conclusions:Patients with permanent enterostomy for colorectal cancer have a high overall score of demoralization syndrome, and a high proportion of patients with moderate to severe demoralization. Medical and nursing staff should focus on patients in remote rural areas and those with poor self-care abilities to stomas, develop targeted intervention measures to improve patients' negative emotions, enhance their self-disclosure, and pay attention to strengthening social support to relieve their demoralization syndrome, thereby improving their quality of life.

Objective To analyze the characteristics of time in range(TIR)and its relationship with oxidative stress(OS)and insulin resistance status(HOMA-IR)in patients with type 2 diabetes mellitus(T2DM)and sleep apnea-hypopnea syndrome(OSAHS).Methods According to apnea-hypopnea index(AHI),165 T2DM in patients were divided into simple T2DM group(AHI<5 times/h,n=43),T2DM combine OSAHS mild group(OSAHS-G,5≤AHI<15 times/h,n=51),T2DM combined OSAHS moderate group(OSAHS-M,15≤AHI≤30 times/h,n=40)and T2DM combine OSAHS severe group(OSAHS-S,AHI>30 times/h,n=31).TIR was calculated by dynamic blood glucose monitoring.Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and other indexes were detected and analyzed.Results Compared with simple T2DM group,the levels of HOMA-IR,8-iso-PGF2a and Ox-LDL were higher in T2DM combined OSAHS-G,OSAHS-M or OSAHS-S group,while the levels of TIR,SOD and GSH-Px were lower(P<0.05).Pearson correlation analysis showed that TIR was positively correlated with the levels of SOD and GSH-Px(P<0.05 or P<0.01),and negatively correlated with the levels of 8-iso-PGF2a,Ox-LDL,HbA1c,HOMA-IR and the severity of OSAHS(P<0.01).Logistic regression analysis showed that TIR,SOD and GSH-Px were protective factors for severe OSAHS in T2DM patients,while 8-iso-PGE2a and Ox-LDL were the risk factors for severe OSAHS.Conclusions The glucose level fluctuates greatly in patients with T2DM and OSAHS.Insulin resistance and oxidative stress are factors that affect the normalization of TIR.

In order to standardize the quality control of traditional Chinese medicine（TCM） dispensing granules， the Chinese Pharmacopoeia Commission has promulgated and implemented 200 national drug standards for TCM dispensing granules， but there are still varieties of TCM dispensing granules without unified standards. Many provinces have actively invested in the formulation of provincial standards for TCM dispensing granules to make up for the gaps in standards for varieties of traditional Chinese medicine dispensing granules other than the national standards. By the end of July 2022， 29 provincial-level administrative regions have successively promulgated and implemented a total of 5 602 provincial standards for TCM dispensing granules， involving more than 400 varieties. In order to better understand the formulation and characteristics of provincial standards， this study took 105 provincial standards that have been promulgated and implemented in Henan province as an example， and comprehensively analyzed the formulation and characteristics through quality control indicators such as dry extract rate of raw materials， contents of index components and their transfer rates， specifications and so on. The formulation and characteristics of the same TCM dispensing granules in the provincial standards of different provinces were further analyzed， in order to provide reference for the formulation of provincial standards of TCM dispensing granules and the implementation of national standards.

ObjectiveTo investigate the feasibility of applying electronic nose technology to rapidly identify Bletillae Rhizoma and its approximate decoction pieces. MethodA total of 134 batches of Bletillae Rhizoma and its approximate decoction pieces， including 45 batches of Bletillae Rhizoma， 30 batches of Gastrodiae Rhizoma， 30 batches of Polygonati Odorati Rhizoma and 29 batches of Bletillae Ochraceae Rhizoma， were collected as test samples. The olfactory sensory data of the samples were collected by PEN3 electronic nose as the independent variable（X）. Based on the identification results of the 2020 edition of Chinese Pharmacopoeia and local standards， as well as the high performance liquid chromatography（HPLC） fingerprint and original purchase information of 134 batches of the decoction pieces， the benchmark data Y of the identification model were obtained， and four chemometric methods of principal component analysis-discriminant analysis（PCA-DA）， partial least squares-discriminant analysis（PLS-DA）， least square-support vector machine（LS-SVM） and K-nearest neighbor（KNN） were used to establish the binary identification model for 45 batches of Bletillae Rhizoma and 89 batches of non-Bletillae Rhizoma and the quadratic identification model of the four kinds of decoction pieces， that is， Y=F（X）. ResultAfter leave-one-out cross validation， the positive discrimination rates of the above four models were 97.01%， 97.01%， 98.51% and 97.01% in the binary identification， and 97.76%， 89.55%， 98.51% and 97.01% in the quadratic identification， respectively. The highest positive discrimination rate could reach 98.51% for the binary and quadratic identification models， and LS-SVM algorithm is both the optimal one， the most suitable kernel functions were chosen as radial basis function and linear kernel function， respectively. The optimal models discriminated well with no unclassified samples. ConclusionElectronic nose technology can accurately and rapidly identify Bletillae Rhizoma and its approximate decoction pieces， which can provide new ideas and methods for rapid quality evaluation of other decoction pieces.

The content validity index of the scale level was 0.984, and the cumulative variance contribution rate was 59.688%.Conclusions:The reliability and validity of the Elderly Inpatient Falls Prevention Knowledge, Attitude and Practice Scale for Full-time Caregivers are good, and can be used as a tool to evaluate the full-time caregiver knowledge, attitude and practice for preventing falls in elderly inpatients.

Objective:To evaluate the role of cathepsin B (CTSB) in mechanical ventilator-induced lung injury (VILI) in rats and the relationship with NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome.Methods:Thirty-six SPF-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 220-300 g, were divided into 3 groups ( n=12 each) by the random number table method: control group (group C), VILI group (group V) and VILI + CA074-me group (group Me). CA074-me 5 mg/kg was intraperitoneally injected in group Me, while the equal volume of normal saline was given instead in group C and group V. Group C kept spontaneous breathing for 4 h, and the animals were mechanically ventilated (tidal volume 20 ml/kg, respiratory rate 80 breaths/min, fraction of inspired oxygen 21%, PEEP 0 cmH 2O). Blood samples from femoral artery were collected for arterial blood gas analysis before tracheal intubation and after spontaneous breathing or ventilation, and PaO 2 was recorded.Rats were sacrificed, and bronchoalveolar lavage fluid (BALF) was collected and lung tissues were collected for determination of the wet/dry lung weight ratio (W/D ratio), serum interleukin-1beta (IL-1β) and IL-18 concentrations in BALF (by enzyme-linked immunosorbent assay), expression of CTSB, NLRP3, apoptosis-associated speck-like protein containing a caspase-1 recruitment domain (ASC) and caspase-1 mRNA in lung tissues (quantitative real-time polymerase chain reaction), and expression of CTSB, NLRP3, ASC and caspase-1 in lung tissues (by Western blot) and for microscopic examination of the pathological changes (using HE staining). Lung injury was assessed and scored. Results:Compared with group C, PaO 2 was significantly decreased after the end of ventilation, the lung injury score, W/D ratio and concentrations of IL-1β and IL-18 in serum and BALF were increased, and the expression of CTSB, NLRP3, ASC and caspase-1 protein and mRNA in lung tissues was up-regulated in group V and group Me ( P<0.01). Compared with group V, PaO 2 was significantly increased after the end of ventilation, the lung injury score, W/D ratio and concentrations of IL-1β and IL-18 in serum and BALF were decreased, and the expression of CTSB, NLRP3, ASC and caspase-1 protein and mRNA in lung tissues was down-regulated in group Me ( P<0.01). Conclusions:CTSB is involved in VILI in the rats, and the mechanism may be related to activation of NLRP3 inflammasomes.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

Objective:To explore the relationships among perceived social constraints, social participation, as well as anxiety and depression in first stroke patients, and to further analyze the mediating effect of social participation on these variables.Methods:A total of 216 first stroke patients in the Department of Neurology of Affiliated Hospital of Qingdao University from April to December 2020 were recruited by convenience sampling and investigated by general information questionnaire, Social Constraints Scale (SCS), Chinese version of Impact on Participation and Autonomy Questionaire (IPA-C) and Hospital Anxiety and Depression Scale (HADS).Results:The total score of SCS, IPA-C, depression and anxiety were 33.49 ± 6.81, 43.42 ± 9.62, 8.05 ± 4.15 and 8.61 ± 2.59. Social constraints were positively correlated with social participation as well as anxiety ( r=0.644, 0.383, both P<0.05). Social constraints were positively correlated with social participation as well as depression ( r=0.482, 0.371, both P<0.05). The quality of social participation partially mediated the relationship between social constraints and anxiety (intermediary effect was 0.119), and also partially mediated the relationship between social constraints and depression (intermediary effect was 0.270). Conclusions:First stroke patients experience high level of social constraints, low quality of social participation and severe anxiety and depression. Social constraints can affect anxiety and depression through social participation. Medical staff should build a good environment to meet the needs of stroke patients of social participation, help patients to establish a correct psychological coping style, reduce patients' avoidance of social participation due to perceived constraints and exclusion, and thus promote the mental health of patients.

Objective:To develop the Health Promotion Behavior Intention Questionnaire for enterostomy patients and test its reliability and validity.Method:Based on the theory of planned behavior, the first draft of the questionnaire was formed through literature review, group discussion, correspondence with Delphi experts and pre-test. The convenient sampling method was used to select 419 patients with enterostomy who visited Stoma Outpatient Department of the Affiliated Hospital of Qingdao University from December 2020 to June 2021 to conduct a questionnaire survey. Item analysis and reliability and validity tests were carried out on the questionnaires.Results:The Health Promotion Behavior Intention Questionnaire for enterostomy patients included 15 items. Exploratory factor analysis extracted four common factors, namely, attitude, subjective norm, perceived behavioral control and behavioral intention. The cumulative variance contribution rate was 83.166%. The content validity index of item level was 0.875-1.000 and the content validity index of questionnaire level was 0.983. The Cronbach's α coefficient of the total questionnaire was 0.921 and the retest reliability coefficient was 0.848.Conclusions:The Health Promotion Behavior Intention Questionnaire for enterostomy patients has good reliability and validity and it can be used as a tool to evaluate the health promotion behavior intention of patients with enterostomy.

Objective:To compare the clinical efficacy between femoral neck system (FNS) and inverted cannulated compression screws (ICCS) in the fixation of adult femoral neck fracture.Methods:The clinical data were retrospectively analyzed of the 119 patients with femoral neck fracture who had received FNS or ICCS internal fixation at Department of Traumatic Orthopedics, West China Hospital from September 2019 to June 2020. They were divided into 2 groups according to their internal fixation methods. In the FNS group of 62 patients, there were 38 males and 24 females, with an age of (54.0±13.0) years, and 13 cases of type Ⅱ, 34 cases of type Ⅲ and 15 cases of type Ⅳ according to the Garden classification; in the ICCS group of 57 patients, there were 42 males and 15 females, with an age of (53.2±11.3) years, and 9 cases of type Ⅱ, 33 cases of type Ⅲ and 15 cases of type Ⅳ according to the Garden classification. The operation time, intraoperative blood loss, fluoroscopy frequency, hospitalization time, fracture healing time, Harris hip score and incidence of complications were compared between the 2 groups.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data or follow-up duration ( P>0.05). There were significant differences between the FNS and ICCS groups in fluoroscopy frequency [(8.8±2.9) times versus (15.6±3.4) times], operation time [(45.2±10.1) min versus (51.8±11.7) min], fracture healing time [(3.2±0.4) months versus (4.0±0.6) months], Harris hip score at the last follow-up [(91.8±4.4) points versus (84.6±3.3) points], and femoral neck shortening at the last follow-up, favoring the FNS group (all P<0.05). There were no significant differences in follow-up time, hospitalization time, intraoperative blood loss or incidence of complications between the 2 groups ( P>0.05). Conclusions:In the fixation of adult femoral neck fractures, compared with ICCS, FNS can significantly reduce fluoroscopy frequency, shorten fracture healing and operation time, reduce risk of femoral neck shortening and hospitalization time, and promote functional recovery of the hip.
