Objective:To observe the effects of warm acupuncture on post-stroke cognitive impairment (PSCI) based on the theory of intestinal flora.Methods:A randomized controlled trial was conducted. 60 patients with PSCI in the Department of Acupuncture and Neurology of the First Affiliated Hospital of Xinjiang Medical University from October 2020 to June 2022 were selected as the observation objects, and were divided into 2 groups by random number table, with 30 cases in each group. On the basis of cognitive rehabilitation training, the treatment group was given warm acupuncture treatment, and the control group was given routine acupuncture treatment. 2 groups were treated for 4 weeks as 1 course, and a total of 4 courses were treated. Montreal cognitive assessment (MoCA) was used to assess patients' cognitive function before and after treatment, and mini-mental state examination (MMSE) was used to assess patients' intelligence level. The numbers of bifidobacteria and lactic acid bacteria in fecal samples were calculated, and plasma gamma-aminobutyric acid (GABA) levels were detected by ELISA to evaluate the clinical efficacy.Results:During the study, 1 case was lost in each of the two groups, and finally 29 cases were included in the curative effect statistics. The total effective rate was 79.3% (23/29) in the treatment group and 65.5% (19/29) in the control group, with statistical significance ( χ2=43.39， P<0.05). After treatment, MoCA score [(24.23±1.36) vs. (21.26±1.30), t=3.12] and MMSE score [(25.35±1.24) vs. (21.52±1.22), t=3.25] in the treatment group were higher than those in the control group ( P<0.05); Bifidobacterium [(9.20±1.25) LgCFU/g vs. (7.23±1.21) LgCFU/g, t=2.98], Lactic acid bacteria [(8.24±1.12) LgCFU/g vs. (6.25±1.22) LgCFU/g, t=2.92], and the level of GABA [(283.80±83.54) mmol/L vs. (264.76±61.38) mmol/L, t=10.54] were higher than those in the control group ( P<0.05 or P<0.01). Conclusion:Warm acupuncture and moxibustion can effectively regulate the number of intestinal beneficial bacteria in PSCI patients, increase the level of GABA, promote brain tissue repair and improve cognitive function.

Objective:To analyze the status and influencing factors of empathy fatigue in hospice nurses based on ABC-X model (A: stressor event; B:resources available to a family; C: family sperceptions of the stressor; X: likelihood of crisis), so as to provide a reliable basis for developing comprehensive intervention strategies.Methods:A total of 325 nurses engaged in hospice care in China from April 2022 to June 2022 were selected by convenient sampling method. The influencing factors of empathy fatigue of hospice care nurses were analyzed by ABC-X model (working environment, resilience and coping style). The hospice care nurses were investigated by self-made general questionnaire, Chinese version of Empathy Fatigue Scale, Simplified Coping Style Questionnaire, Coping Style Resilience Scale and Nursing Work Environment Scale. The statistical analysis was performed by SPSS.26.0 statistical software.Results:There were 316 females and 9 males with age of (33.0 ± 7.9) years old. The total score of empathy fatigue in 325 hospice nurses was (91.16 ± 9.60) points, the scores of empathy satisfaction, ocupational burnout and secondary traumatic stress were (31.35 ± 6.01), (28.43 ± 5.86), (31.38 ± 5.76) points respectively. The scores of positive coping style, negative coping style, psychological resilience and nursing working environment were (37.46 ± 5.69), (21.28 ± 6.90), (89.84 ± 16.46), (117.13 ± 19.95) points respectively. The negative predictive factor for empathy satisfaction among nurses with the professional title of palliative care ( t=-4.22, P<0.05), and the positive predictive factors for simple coping strategies, psychological resilience, and nursing work environment ( t=4.52, 3.05, 9.03, all P<0.05), could explain 56.7% of the total variation. Psychological resilience, simplified coping strategies, nursing work environment were negative predictive factors for occupational burnout among hospice nurses ( t=-6.93, -3.54, -2.51, all P<0.05), while work nature was a positive predictive factor ( t=2.36, P<0.05), which could explain 49.4% of the total variation. Simplified coping strategies, psychological resilience, and nursing work environment were all negative predictors of secondary traumatic stress in hospice nurses ( t=-5.40, -3.25, -5.95, all P<0.05), which could explain 48.8% of the total variation. Conclusions:Based on the ABC-X model, it is found that the empathic fatigue of hospice nurses is mainly affected by the nursing work environment, mental resilience and coping styles. It is necessary for nursing managers to actively take measures to improve the working environment and coping styles of nurses, enhance their mental resilience and reduce their empathic fatigue.

Sjögren's syndrome （SS）， a disorder of immune system， is one of the dominant diseases treated by traditional Chinese medicine （TCM）. China Association of Chinese Medicine organized experts in the field of TCM and western medicine rheumatology and pharmacology to discuss the advantages and optimal regimens of TCM for the treatment of SS. The experts generally agreed on the low early diagnosis rate of SS and the lack of targeted therapeutic drugs. In addition， autoimmune abnormality is the key factor in the occurrence of SS and deficiency of both Qi and Yin is the core pathogenesis. SS has unique tongue manifestations， which is expected to allow for the early diagnosis and treatment with integrated traditional Chinese and western medicine. TCM has advantages in treating SS in terms of alleviating clinical symptoms and systemic involvement， individualized treatment， relieving sleep and mood disorders， preventing the occurrence in the early stage， and enhancing the effectiveness and reducing toxicity in the treatment by integrated TCM and western medicine. In general， TCM has advantages in different stages of SS. Internal and external use of TCM， acupuncture， and acupotome are all available options. The optimal regimens should be determined on the basis of pattern identification， stage of disease， and the advantages of TCM. Clinical characteristics and biomarkers of SS should be studied to classify patients， so as to design precision evidence-based TCM regimens for SS. On the basis of unique tongue manifestations of SS， models for early diagnosis and poor prognosis identification of SS should also be established to achieve early prevention and treatment and to improve the prognosis. In the future， we should vigorously carry out high-quality evidence-based medical research on the treatment of SS by TCM and integrated traditional Chinese and western medicine and develop relevant guidelines to optimize and standardize current diagnosis and treatment， thereby laying a basis for clarifying and explaining the advantages of TCM in treating SS.

Objective:To investigate the diagnostic values of human epididymis protein 4 (HE4), endothelial cell specific molecule-1 (ESM-1) and epidermal growth factor receptor (EGFR) for lung cancer.Methods:The clinical data of 90 patients with lung cancer and 50 patients with benign lung diseases diagnosed by the pathological examination in Tangshan People's Hospital from December 2019 to January 2021 were retrospectively analyzed, and 40 healthy physical examiners in the same period were selected as the controls. The serum HE4 levels were detected by electrochemiluminescence method. The serum ESM-1 and EGFR levels were tested by enzyme-linked immunosorbent assay. The differences in serum HE4, ESM-1 and EGFR levels between the three groups were compared; logistic regression analysis was used to screen out the effective indicators for the diagnosis of lung cancer and to construct a prediction model for the diagnosis of lung cancer. Using pathological diagnosis result as the gold standard, the receiver operating characteristic (ROC) curve was drawn, and the diagnostic efficacy of indicators for lung cancer was evaluated.Results:The levels of serum HE4 in lung cancer group, benign lung diseases group and healthy control group were 119.55 pmol/L (82.06 pmol/L, 189.00 pmol/L), 58.84 pmol/L (45.62 pmol/L, 69.41 pmol/L) and 42.67 pmol/L (37.09 pmol/L, 51.84 pmol/L), the levels of ESM-1 were 33.00 ng/ml (25.85 ng/ml, 47.40 ng/ml), 20.14 ng/ml (11.93 ng/ml, 28.90 ng/ml) and 15.39 ng/ml (11.84 ng/ml, 20.19 ng/ml), and the levels of EGFR were 46.60 pg/ml (37.45 pg/ml, 58.98 pg/ml), 32.77 pg/ml (26.27 pg/ml, 40.86 pg/ml) and 30.43 pg/ml (27.54 pg/ml, 35.75 pg/ml), and the differences in each indicator among the three groups were statistically significant (all P < 0.001). The levels of serum HE4, ESM-1 and EGFR in lung cancer group were higher than those in benign lung diseases group and healthy control group. In patients with lung cancer, logistic regression analysis was performed with HE4 (X 1), ESM-1 (X 2) and EGFR (X 3) as the independent variables and pathological diagnosis as the dependent variable, and a lung cancer prediction regression model was established: P = 0.171X 1+0.351X 2+0.184X 3-24.660. The accuracy of this model in predicting lung cancer could reach 98.5%, and serum HE4, ESM-1 and EGFR were risk factors for the occurrence of lung cancer (all P < 0.05). The area under ROC curve from high to low was HE4 (0.960), ESM-1 (0.942) and EGFR (0.859). The diagnostic sensitivity of serum HE4 63.67 pmol/L for lung cancer was 86.7%, and the specificity was 97.5%. Both serum HE4 ( r = 0.304, P = 0.004) and ESM-1 ( r = 0.416, P < 0.001) were correlated with EGFR. Conclusions:Serum HE4, ESM-1 and EGFR can be used as effective indicators for the diagnosis of lung cancer, and the prediction model established based on the three serum tumor markers is of good value for the diagnosis and prediction of lung cancer.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.

Objective:To compare the differences in the delineation of the gross tumor volume (GTV) and lymph nodes of nasopharyngeal carcinoma (NPC) patients using computerized tomography (CT), magnetic resonance imaging (MRI), and 18F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18F-FDG PET/CT), and to investigate the optimal standard uptake value (SUV; relative to the MRI-based delineation) for the automatic delineation of GTV using PET. Methods:A total of 53 NPC patients proposing to receive radiotherapy were selected for this study. The CT, MRI, and PET images of each patient were obtained before radiotherapy. Then GTV and positive lymph nodes were delineated on these three types of images. They were individually named GTV MRI, GTV CT, GTV PET2.5 (SUV=2.5), Lymph MRI, Lymph CT, and Lymph PET2.5 and compared. The GTV ∩2.5 (overlapped GTV) was obtained through the alignment of MRI and PET/CT images. Meanwhile, GTV was delineated on PET images using thresholds of SUV=4.0, 4.5, 5.0, and 5.6, obtaining GTV PET4.0, GTV PET4.5, GTV PET5.0, and GTV PET5.6. Then their volume and Dice similarity coefficients (DSCs) were compared. Results:Compared to GTV MRI, GTV CT decreased by 1.73% ( P>0.05) and GTV PET2.5 increased by 21.34% ( t=-3.52, P < 0.05) in the three types of images. The volume of Lymph PET2.5 was 1.61 and 1.87 times the volume of Lymph MRI and Lymph CT, respectively ( t=-4.12, -5.18; P< 0.05). The volume of high-SUV lymph nodes was 4.07 times the volume of lymph nodes with low SUVs or SUV=0 ( t=5.50, P< 0.05) on PET images. The DSC between GTV PET4.0and GTV MRI was 0.78 ± 0.27, which was lower than that between GTV PET2.5 and GTV MRI (0.84 ± 0.18). However, GTV PET4.0 approximated to GTV ∩2.5 ( P>0.05). Conclusions:Compared to CT and 18F-FDG PET/CT, MRI shows more accurate boundaries of GTV and lymph nodes. When 18F-FDG PET/CT was adopted to automatically delineate GTV, the GTV delineated using SUV=4.0 was closer to GTV MRI.
