Objective:To discuss dominant symptoms and compatibility rules of Dazhui(GV14) based on data mining.Methods:Literature related to Dazhui (GV14) was retrieved from CNKI, Wangfang, VIP, China Biomedical Literature Database (CBM) and Pubmed databases from January 1, 2012 to August 15, 2022, and the main symptoms of Dazhi (GV14) and the compatibility of acupoints were summarized. Gephi 0.9.5 software was used for complex network analysis to compare the treatment for dominant symptoms with single acupoint of Dazhi (GV14) and the compatibility of the acupoint. SPSS Modeler 18.0 software was used to analyze the association rules of acupoint combination based on Apriori algorithm. The clustering analysis of high frequency acupoints was carried out by SPSS Statistics 26.0 software.Results:A total of 722 articles were included, involving 732 prescriptions. The dominant symptoms of single acupoint were cervical spondylosis, acne, and cold; the treatment for dominant symptoms with compatibility included 14 types, such as cervical spondylosis, allergic rhinitis, ischemic stroke sequelae. The meridian compatibility was dominated by bladder meridian, and the frequency of yang meridians was higher than yin meridians. The compatibility of specific acupoints such as Xiahe acupoint, Beishu acupoint and Bahui acupoint were the main acupoints, and the high frequency acupoints were 33 acupoints such as Feishu (BL13), Baihui (GV20), Fengchi (GB20) and Zusanli (ST36), obtaining 4 series and 8 types of compatible combinations of Dazhui (GV14).Conclusions:Dazhui (GV14) is widely used in the treatment of internal diseases, such as respiratory diseases, nervous system diseases and vertebral artery type of cervical spondylosis. It tends to be flexibly used with multiple compatibility and clustering combination of specific acupoints.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Objective:To evaluate the mechanical performance of customized metal prosthesis with tibia stems of varying lengths for tibial bone defects reconstruction.Methods:Morphologically matched postoperative finite element models of bone defect revision were developed, with three gradients (15 mm, 30 mm, and 45 mm) according to the degree of bone defect and were reconstructed with 3D printed tantalum metal prosthesis using three tibial stem lengths (80 mm, 120 mm, and 150 mm), respectively. Conventional static and dynamic (walking gait) loading was performed to analyze the peak tibial stress distribution and accumulated sliding distance at the prosthetic interface, and to assess the effects of the three tibial stems of different lengths on the stability of the customized tibial defect restorations and the internal tibial stress state.Results:The peak accumulated sliding distance of the dynamically loaded morphologically matched restorations ranged from 17.94 to 21.31 mm with static loading, which were 68% to 84.3% higher than those of 10.26 to 11.69 mm with static loading. The peak tibial stresses in the dynamically loaded model were greater than those in the statically loaded model, with an increase of 28%-49.2%, including 132.94-143.88 MPa in the statically loaded model and 170.41-200.14 MPa in the dynamically loaded model. The overall accumulated sliding distance of the tibia prosthetic model gradually decreased from the tibial osteotomy surface, and the accumulated peak sliding distances ranged from 10.26 to 11.69 mm for static loading, and from 17.94 to 21.31 mm for dynamic loading. The bone tissue stresses in the anterolateral and medial-posterior tibia increased gradually from top to bottom, and the maximum stress value in each section was in the posterior medial tibia (the maximum value was 200.14 MPa). The highest bone tissue stress in the lateral tibia was affected by the tibial stem length, which resulted in a different location, and it was the area most affected by stress shielding (maximum value of 170.65 MPa).Conclusion:For stability assessment of morphologically matched tantalum customized prosthesis, physiological gait dynamic loading studies are more reliable than static loading; the choice of tibial stem length depends on a combination of accumulated peak sliding distances and tibial bone stress distribution factors.

Objective:To observe the effect of silicon dioxide (SiO 2) on the polarization of alveolar macrophages (AMs) , and to explore the expressions and the significance of signal transducer and activator of transcription-6 (STAT-6) /Krüppel-like factor-4 (KLF-4) /peroxisome proliferators-activated receptors-γ (PPAR-γ) signaling molecules in AMs. Methods:In November 2020, C57BL/6 mice were randomly divided into crystalline SiO 2 group and normal saline (NS) group, and 12 mice in each group. Mice were intratracheally instillated with 100 μl crystalline SiO 2 suspension (20 mg/ml) or 100 μl NS, and were sacrificed after 28 days. Masson staining was used to observe the degree of pulmonary fibrosis of mice and hydroxyproline (HYP) level were assessed. The proportions of M1-typed and M2-typed AMs in bronchoalveolar lavage fluid (BLAF) were analyzed by flow cytometry. The mRNA relative expression levels of inducible nitric oxide synthase (iNOS) , arginidase-1 (Arg-1) , interleukin (IL) -1β, tumor necrosis factor-α (TNF-α) , IL-6, IL-10, transforming growth factor-β (TGF-β) , STAT-6, KLF-4 and PPAR-γ were detected by real-time fluorescence quantitative PCR. Activities of iNOS and Arg-1, as well as contents of IL-1β, TNF-α, IL-6, IL-10 and TGF-β were assessed by the enzyme-linked immunosorbent. The protein relative expression levels of phosphorylation-signal transducer and activator of transcription-6 (p-STAT-6) , KLF-4 and PPAR-γ were evaluated by immunofluorescence. Results:After 28 days of treatment, the structure of the lung tissue of the mice was destroyed, and the deposition of collagen was significantly increased in the crystalline SiO 2 group. Compared with NS group, HYP level of lung tissue in crystalline SiO 2 group were increased, the proportion of M2-typed AMs in crystalline SiO 2 group was increased, the proportion of M1-typed AMs in crystalline SiO 2 group was decreased, the mRNA relative expressions and contents of Arg-1, IL-10, TGF-β in crystalline SiO 2 group were significantly increased, the mRNA relative expressions and contents of iNOS, IL-1β, TNF-α, IL-6 in crystalline SiO 2 group were significantly decreased, the mRNA of STAT-6, KLF-4, PPAR-γ and the protein relative expression levels of p-STAT-6, KLF-4, PPAR-γ were significantly increased in crystalline SiO 2 group, and the the differences were statistically significant ( P<0.05) . Conclusion:Crystalline SiO 2 may mediate the process of pulmonary fibrosis through promote AMs polarization toward M2-typed by activating the STAT-6/KLF-4/PPAR-γ signaling pathway.

Objective To promote the application of the best evidence for supportive care in the management of depression in patients with head and neck cancer, and to improve the quality of clinical care.Methods Follow the three stages of clinical evidence practice of Joanna Briggs Institute (JBI): baseline review, practice change and effect evaluation, the best evidence of supportive nursing in depression management for head and neck cancer patients were retrieved, and 4 quality review indicators were developed. A total of 50 hospitalized head and neck cancer patients and 12 nurses were selected to collect data by means of field observation, interviews and nursing records. The obstacles to the application of evidence were analyzed and a practical scheme was worked out.Results The nurse's implementation rate of the four review indicators increased from 0-90％ at the baseline review to 90％-100％ after the evidence was applied. Except for Indicator 3 "Indicators nurses introduced the pressure on patients and their families to face cancer", the implementation rates of the other three indicators were significantly improved (P<0.01). After the application of evidence, the incidence of depression was decreased (P<0.05). The score of Relaxation, Sleep and Fatigue Management Knowledge Questionnaire was (18.20±14.09) before the application of evidence, which was lower than that after the application of evidence (80.60±12.84), and the difference was statistically significant (t=-23.14, P<0.01). The nurses' score of Supportive Nursing Knowledge Questionnaire before the application of evidence was (63.83±10.78), which was lower than that after the application of evidence (95.5±3.18), and the difference was statistically significant (t=-9.76,P<0.01).Conclusions The evidence-based application program can standardize nurses' supportive nursing behaviors for patients with depressive symptoms, reduce the severity of depression, improve the self-support knowledge level, and improve the quality of depression management in hospitalized patients with head and neck cancer.

Objective To investigate the prevalence and characteristics of adverse reactions to cosmetics in China,and to provide a basis for further supervision.Methods The diagnosis of adverse reactions to cosmetics was according to 7 national standards (GB17149.1-7-1997) including the A general rule for the diagnosis and management of skin diseases induced by cosmetics.Data regarding gender,age,occupation,educational background,disease types,cosmetic types,and so on,were collected from patients with adverse reactions to cosmetics at 13 surveillance sites in China during 2005-2014.A descriptive statistical analysis was carried out.Results During 2005-2014,a total of 13 534 cases of adverse reactions to cosmetics were reported to the monitoring system.Of these cases,95.40％ (12 912/13 534) were female,and 80.85％ were young or middle-aged (20-44 years).Finally,5 446 cases were confirmed to be adverse reactions to cosmetics,among which,94.66％ (5 155/5 466) were contact dermatitis to cosmetics,and 132 were other types that were not included in the A general rule for the diagnosis and management of skin diseases induced by cosmetics.Among these confirmed cases,14 209 cosmetic products were involved,and ordinary skin care products predominated in these products.The proportion of imported cosmetic products (48.79％,6 932/14 209) was slightly higher than that of domestic products (43.21％,6 139/14 209).The number of reported eases increased by 13.16％ per year from 2005 to 2009,but decreased by 17.96％ per year from 2010 to 2014.Conclusion Adverse reactions to cosmetics are a complicated and important public health issue,and effective measures should be taken based on their characteristics.

Objective To investigate the changes of renal resident dendritic cells (rDC)during kidney ischemia-reperfusion injury (IRI). Methods C57BL/6J mice models with bilateral renal warm ischemia were established. The kidney tissue was prepared for single cell suspension at 24 h and 48 h after reperfusion. The changes in the percentage of CD45 +cells and CD1 1 c +rDCs were evaluated by flow cytometry. The renal tissues of mice labeled with green fluorescent protein and diphtheria toxin receptor (CD1 1 c +GDTR ) were prepared for single cell suspension. The percentage and phenotype of CD1 1 c +rDCs were analyzed by flow cytometry. CD1 1 c +GDTR mice models with bilateral renal warm ischemia were established. The renal tissue was prepared for single cell suspension at 24 h after reperfusion. CD45 + cells was gathered by magnetic-activated cell separation (MACS ). The expression levels of co-stimulatory molecules on the rDC surface were analyzed by flow cytometry. Results At 24 h after reperfusion,the percentage of CD45 +cells in the kidney of C57BL/6J mice was significantly elevated,and further increased at 48 h after reperfusion. At 24 h after reperfusion,the quantity of CD1 1 c +rDCs was equally increased,whereas the percentage of CD1 1 c +rDCs in CD45 +cells was dramatically declined and restored at 48 h after reperfusion,slightly higher compared with that in the sham group. In healthy CD1 1 c +GDTR mice,the percentage of CD45 +cells in the kidney was lower than 1%,consisting of approximately 40%of CD1 1 c +rDCs,which mainly presented as CD11bintF4/80 -MHCⅡ+. At 24 h after reperfusion,the percentage of CD11c +F4/80 -subset rDC surface co-stimulatory molecules was significantly enhanced,such as CD40,CD80 and CD86. Conclusions Following warm IRI,the percentage and quantity of rDCs,and the expression level of rDC surface co-stimulatory molecule are significantly increased,prompting that renal rDC infiltration is increased and phenotype becomes matured.
