The historical development of endogenous wind （内风） is traced with time as the thread， based on the progression of factors such as syndromes， causes of disease， and pathogenesis. It is believed that the concept of wind syndrome originated in The Inner Canon of Yellow Emperor （《黄帝内经》）， encompassing both exogenous wind （外风） and endogenous wind syndrome. Over time， exogenous wind syndrome gradually evolved into mild syndromes and severe syndromes， while endogenous wind syndrome emerged from severe syndromes of exogenous wind. Endogenous wind syndrome has both syndrome and pathogenic attributes， and its theoretical system has gradually become more refined. Based on the theories of ancient and modern medical practitioners， and combining the holistic perspectives with Xiang （象） thinking， it is proposed that endogenous wind has both physiological and pathological distinctions. The physiological endogenous wind refers to the liver's moderate dispersing and regulating function， which helps to distribute qi （气）， blood， and body fluids， while pathological endogenous wind arises from abnormal liver dispersal. Therefore， in clinical practice， different treatment methods， such as tonifying， unblocking， and warming， can be applied according to the differentiation of deficiency and excess in the pathogenesis.

OBJECTIVE: To compare the effectiveness and shoulder function of reverse total shoulder arthroplasty (RTSA) and open reduction and internal fixation (ORIF) in the treatment of Neer three/four-part proximal humeral fractures in the elderly. METHODS: Randomized controlled analysis was conducted on 68 patients over 70 years old with Neer three/four-part proximal humeral fractures treated with RTSA or ORIF between January 2020 and June 2022. The patients were randomly divided into RTSA group ( n=32) and ORIF group ( n=36). There was no significant difference ( P>0.05) in the baseline data such as age, gender, body mass index, injured side, Neer classification, and preoperative Charlson comorbidity index, visual analogue scale (VAS) score, Constant shoulder score, Oxford shoulder score (OSS), and hemoglobin (Hb). The operation time, intraoperative blood loss, reduction of Hb on the 3rd day after operation, hospital stay, total cost of hospitalization, complication incidence, range of motion of shoulder joint at 2 years after operation, VAS score before operation and at 5 days and 1 month after operation, Constant shoulder score and OSS score before operation and at 2 years after operation, and imaging results during follow-up were recorded and compared between the two groups. RESULTS: Compared with the ORIF group, the RTSA group had longer operation time, less intraoperative blood loss, and higher total cost of hospitalization ( P<0.05). There was no significant difference in Hb reduction on the 3rd day after operation between the two groups ( P>0.05). The VAS scores significantly improved in both groups at 5 days and 1 month after operation ( P<0.05), but there was no significant difference between the two groups ( P>0.05). All patients were followed up 26-35 months, with an average of 31.2 months. In the RTSA group, there were 2 cases of poor healing of superficial incision and 1 case of transient nerve injury. There was no complication such as bone resorption around the prosthesis, lucent band, prosthesis loosening, or periprosthetic fracture in all patients. In the ORIF group, there was 1 case of poor healing of superficial incision, 3 cases of nonunion of fracture, 1 case of arthritis secondary to humeral head necrosis, and 1 case of bone absorption of large tuberosity, and no displacement or fracture failure of internal fixation was found in all patients. There was no significant difference in the incidence of complications [9.4% (3/32) vs 16.7% (6/36)] between the two groups [ OR (95% CI): 0.828 (0.171, 4.014), P=0.814]. In the RTSA group, 28 cases were graded 0 and 4 cases were graded 1 at 2 years after operation. Constant and OSS scores of RTSA group were significantly better than those of ORIF group ( P<0.05). The Constant score was significantly better than ORIF group in activity and strength, range of motion, lifting, abduction, and external rotation ( P<0.05), and there was no significant difference in pain, daily function, and internal rotation between the two groups ( P>0.05). The RTSA group had a significantly greater range of motion in lifting, abduction, and external rotation than ORIF group ( P<0.05), but there was no significant difference in internal rotation between the two groups ( P>0.05). CONCLUSION Application of RTSA as the initial treatment of Neer three/four-part proximal humeral fractures in the elderly can achieve better rehabilitation of joint activity and lower risk of early reoperation, and improve the quality of life of elderly fracture patients. However, the difficulty of revision and the high cost of treatment require the surgeon to pay full attention and strictly grasp the indications.

Outpatient humanistic care refered to providing a full process of caring medical services to outpatients. In order to standardize the human caring services for outpatients in medical institutions, promote the comprehensive service level of outpatient services, and improve the patient′s medical experience, Chinese Association for Life Care issued the group standard of Management Norms for Human caring of Outpatients in April 2023. This standard clarified the relevant terms and definitions of human caring for outpatients, specified the basic requirements for human caring, the humanistic quality and care responsibilities of outpatient staff, the outpatient care environment and facilities, the outpatient care process and measures, and quality management. It designed standardized and personalized full process care service norms, providing references for medical institutions at all levels to promote the development of human caring for outpatients.

Objective:To investigate the effect of macrophage-derived exosomes on the morphological transformation of Candida albicans (CA), and to explore the underlying mechanisms.Methods:In vitro cultured human acute monocytic leukemia cell line THP-1 was induced and differentiated into M0 macrophages using the phorbol ester PMA. CA was activated and prepared as the fungal suspension. M0 macrophages were infected with the CA suspension, and the process of cell phagocytosis was observed under a high-content imaging analysis system. M0 macrophage-derived exosomes (exosome group) and CA-infected M0 macrophage-derived exosomes (CA exosome group) were extracted by differential centrifugation; transmission electron microscopy, nanoparticle tracking analysis, and Western blot analysis were performed to identify and compare exosomes in the two groups. The exosomes from the two groups were separately co-cultured with CA (exosome-treated group and CA exosome-treated group), and independently cultured CA served as the blank control group; the morphological changes of CA were observed under an inverted microscope, the intracellular cyclic adenosine monophosphate (cAMP) contents were detected by the enzyme-linked immunosorbent assay (ELISA), and the expression levels of cAMP-related genes, RAS1 and CDC35 (also known as Cyr1), were detected by real-time quantitative PCR (RT-qPCR) . Results:Western blot analysis showed that exosomes from the exosome group and CA exosome group both expressed the tumor susceptibility gene 101 protein (TSG101, an exosome marker), and did not express calnexin (a negative marker) ; transmission electron microscopy and nanoparticle tracking analysis showed no significant differences in the morphology or size of the exosomes between the two groups. Compared with the blank control group, the exosome-treated group and CA exosome-treated group both showed obvious inhibition of the yeast-to-mycelial phase transition of CA, with a noticeable reduction in the length of the hyphae under the inverted microscope. ELISA revealed that the intracellular cAMP content in CA significantly decreased in the exosome-treated group and CA exosome-treated group (16.70 ± 0.84 pmol/ml, 16.82 ± 0.87 pmol/ml, respectively) compared with the blank control group (21.82 ± 1.08 pmol/ml; t = 6.45, 6.23, respectively, both P = 0.003). RT-qPCR revealed that the expression of the cAMP-related genes, RAS1 and CDC35, was down-regulated in the exosome-treated group and CA exosome-treated group compared with the blank control group (all P < 0.01), and the RAS1 mRNA expression was significantly lower in the CA exosome-treated group than in the exosome-treated group ( t = 7.43, P = 0.002) . Conclusion:Both M0 macrophage-derived exosomes and CA-infected M0 macrophage-derived exosomes could effectively inhibit the mycelial growth of CA, and the latter one exhibited a stronger inhibitory effect, possibly by down-regulating cAMP in the cAMP/protein kinase A pathway.

Background Heavy metals may play an important role in environmental risk factors associated disorders of activities of daily living (ADL) in older adults. Objective To investigate the associations between plasma levels of six heavy metals (zinc, arsenic, cadmium, lead, manganese, and copper) and ADL disorders in older adults. Methods A cross-sectional survey was conducted from 2018 to 2019 among 1412 rural elderly people in Gongcheng Yao Autonomous County, Guangxi Zhuang Autonomous Region. The plasma metal concentrations were detected by inductively coupled plasma mass spectrometry (ICP-MS), and subsequently classified into three groups (T1-T3) based on tertiles, with the T1 group as the reference. The samples were assessed for ADL disorders using the ADL scale. Logistic regression and restricted cubic spline model (RCS) were used to estimate the odds ratio (OR) and 95% confidence interval (CI) to assess the associations between heavy metals and the prevalence of reporting ADL disorders. Results The mean age of the study population was (68.52 ± 5.92) years, 825 (58.4%) female and 587 (41.6%) male. Of these, 372 (26.34%) subjects reported ADL disorders, and most of them were female (74.30%). The results of logistic regression showed that the participants in the cadmium T2 group (0.15-0.25 µg·L⁻¹) had a higher risk of ADL disorders compared to the T1 group (≤0.15 μg·L⁻¹) (OR=1.552, 95%CI: 1.086, 2.134). After stratification by sex, the relative risk of ADL disorders was lower in the plasma copper T3 group (>1019.58 µg·L⁻¹) compared to the T1 group (≤868.12 μg·L⁻¹) in men (OR=0.481, 95%CI: 0.232, 0.998). The relative risk of ADL disorders was higher in the plasma cadmium T2 group (0.15-0.25 µg·L⁻¹) compared to the T1 group (≤0.15 μg·L⁻¹) in women (OR=1.758, 95%CI: 1.182, 2.616). The RCS results showed that the risk of ADL disorders in men was nonlinearly associated with copper (P_nonlinear=0.011, P_overall<0.05). Conclusion High levels of cadmium are positively associated with the risk of reporting ADL disorders, while high levels of copper are negatively associated with the risk of reporting ADL disorders in men.

BACKGROUND:The results of in vivo and in vitro studies showed that catalpol from Rehmannia glutinosa can significantly reduce the level of inflammatory indexes in the synovial tissue of rats with knee osteoarthritis,and meanwhile,it can delay the progression of knee osteoarthritis.But whether catalpol from Rehmannia glutinosa affects chondrocyte senescence and then delay the progression of knee osteoarthritis has not yet been clarified. OBJECTIVE:To investigate investigate whether catalpol from Rehmannia glutinosa could regulate ATDC5 chondrocyte senescence and the possible mechanisms. METHODS:ATDC5 chondrocytes were divided into blank group(0.1%bovine serum albumin),model group(0.1%bovine serum albumin+1 μmol/L adriamycin),low-dose catalpol group(0.1%bovine serum albumin+1 μmol/L adriamycin+20 μmol/L catalpol from Rehmannia glutinosa)and high-dose catalpol group(0.1%bovine serum albumin+1 μmol/L adriamycin+80 μmol/L catalpol from Rehmannia glutinosa).Adriamycin-induced ATDC5 chondrocyte senescence model was constructed,and the corresponding treatments were given according to the above groups.Cell counting kit-8 assay was used to detect the effects of catalpol from Rehmannia glutinosa on ATDC5 chondrocyte viability,and to screen the optimal concentration of catalpol from Rehmannia glutinosa.The senescence of ATDC5 chondrocytes in each group was detected by β-galactosidase staining after the corresponding treatments.Real-time fluorescence quantitative PCR and western blot were used to detect the mRNA and protein expression of P21,P53,type II collagen,matrix metalloproteinase 13,and interleukin-6.Immunofluorescence method was used to detect the expression of P21,P53 and type II collagen.Flow cytometry was used to detect apoptosis in each group. RESULTS AND CONCLUSION:ATDC5 chondrocytes were identified to be successfully induced and senescence model was induced.Catalpol from Rehmannia glutinosa at the concentrations of 0,20,40,and 80 μmol/L showed no significant effects on the cell viability,suggesting that catalpol from Rehmannia glutinosa is non-cytotoxic and can be used safely(P>0.05);when the concentration was≥100 μmol/L,the cell viability was reduced,suggesting that there may be cytotoxic.Therefore,80 μmol/L was chosen as the high dose for subsequent experiments in this study.The percentage of positive cells in the model group was(86.93±2.18)%,which was significantly higher than that in the blank group[(17.32±0.72)%;P<0.05].Compared with the model group,the percentage of positive cells was significantly lower in the low-and high-dose catalpol groups[(57.28±1.73)%and(27.18±0.97)%,respectively;both P<0.05].Compared with the model group,the relative expression of P21,P53,matrix metalloproteinase 13,and interleukin-6 at mRNA and protein levels was significantly downregulated in the low-and high-dose catalpol groups,while the relative expression of type II collagen at mRNA and protein levels was significantly upregulated in both groups(P<0.05),especially in the high-dose catalpol group(P<0.05).Compared with the model group,the fluorescence intensities of P21 and P53 were significantly weakened in the low-and high-dose catalpol groups,while the fluorescence intensity of type II collagen was significantly enhanced in the low-and high-dose catalpol groups(P<0.05),especially in the high-dose catalpol group(P<0.05).The cell apoptosis detected by Annexin V/PI method showed that there was no significant difference between the model group and the blank group(P>0.05);compared with the model group,the apoptotic index was significantly elevated in the low-and high-dose catalpol groups,especially in the high-dose catalpol group(P<0.05).To conclude,catalpol from Rehmannia glutinosa can slow the progression of osteoarthritis by promoting apoptosis of senescent ATDC5 chondrocytes,further removing senescent ATDC5 chondrocytes,and decreasing the senescence-associated phenotypes.

Objective:To analyze functional changes in macrophages in mouse models of vulvovaginal candidiasis (VVC) by modulating indoleamine 2,3-dioxygenase 1 (IDO1) .Methods:Forty specific-pathogen-free female ICR mice were randomly divided into 4 groups using a complete randomization method: a blank group, a VVC model group, a VVC model + 1-methyltryptophan (1-MT) group (referred to as the 1-MT group), a VVC model + interferon-γ (IFN-γ) group (referred to as the IFN-γ group), with 10 mice in each group. Except for the blank group, all the mice were injected subcutaneously with estradiol benzoate oil solution in the abdomen every other day for 6 days prior to modeling to induce pseudoestrus; after successful induction of pseudoestrus, the mice were inoculated vaginally with Candida albicans suspensions at a concentration of 2 × 10 9 CFU/ml once a day for 5 days to establish VVC mouse models, and subcutaneous injections of estradiol benzoate oil solution were continued simultaneously to maintain the pseudoestrus state; 1 day before inoculation with fungal suspensions, mice in the 1-MT group and IFN-γ group were pretreated with 1-MT and IFN-γ respectively, followed by once-daily same intervention for 6 consecutive days; mice in the blank group and VVC model group were intraperitoneally injected with physiological saline solution once a day for 6 consecutive days. On the 5th day of modeling, vaginal conditions in mice were observed and vaginal symptoms were scored; the vaginal lavage fluid was collected for smear microscopy and fungal colony counting; then, the mice were sacrificed, the vaginal tissues were collected and subjected to hematoxylin-eosin (HE) staining and periodic acid-Schiff (PAS) staining, and the expression of IDO1 and the macrophage surface marker F4/80 was determined in the vaginal tissues by an immunofluorescence method; real-time fluorescence-based quantitative PCR (qPCR) was performed to determine mRNA expression levels of IDO1, inducible nitric oxide synthase (iNOS), and arginase 1 (Arg-1) in the vaginal tissues, and Western blot analysis to determine the IDO1 protein expression in the vaginal tissues. One-way analysis of variance was used to analyze the differences in indices among groups, and Tukey test was used for multiple comparisons. Results:Smear microscopic examination of the vaginal lavage fluid on the 5th day of modeling showed elongated hyphae with a few spores in the VVC model group, a large number of elongated hyphae aggregating in clusters with surrounding spores in the 1-MT group, and a few thin and short hyphae with a large number of spores in the IFN-γ group. Compared with the VVC model group (360.0 ± 15.9), the fungal colony counts in the vaginal lavage fluid significantly increased in the 1-MT group (523.7 ± 67.7, P = 0.002), but significantly decreased in the IFN-γ group (258.3 ± 27.57, P = 0.026). HE staining and PAS staining showed small abscess formation in the epidermis and predominant infiltration of neutrophils throughout the epidermal and dermal layers with a large number of spores and a few hyphae in the VVC model group; thickened epidermis and diffuse inflammatory infiltration predominated by neutrophils in the dermis were seen in the 1-MT group, with a large number of hyphae and spores aggregating into clusters, which were predominated by hyphae; in the IFN-γ group, spores aggregated in the epidermis without obvious hyphae, and a small amount of inflammatory cells predominated by neutrophils infiltrated the dermis. Immunofluorescence assay revealed that the relative fluorescence intensities of IDO1 and F4/80 were highest in the IFN-γ group and the 1-MT group, respectively. Western blot analysis revealed that the IDO1 protein expression in the VVC model group was significantly higher than that in the blank group ( P < 0.001) and the 1-MT group ( P < 0.05), but significantly lower than that in the IFN-γ group ( P < 0.05). qPCR showed that iNOS mRNA expression significantly increased in the VVC model group compared with the blank group ( P < 0.01), and increased in the IFN-γ group compared with the blank group, VVC model group and 1-MT group (all P < 0.001); Arg-1 mRNA expression significantly increased in the VVC model group compared with the blank group ( P < 0.001) and IFN-γ group ( P < 0.01), and increased in the 1-MT group compared with the blank group, VVC model group, and IFN-γ group (all P < 0.001) . Conclusion:In the VVC mouse models, upregulation of IDO1 may cause macrophage polarization toward the M1 phenotype, and inhibition of IDO1 may cause increased macrophage recruitment and exacerbate the inflammatory response.

Objective:To investigate the current situation and influencing factors of patients′ satisfaction with nursing humanistic care, and to provide reference for improving the quality of such care provided by hospitals.Methods:From July to August 2022, outpatients and inpatients in 30 provinces were selected by multi-stage stratified sampling as the survey objects. A cross-sectional survey was conducted on an online platform, using the general information questionnaire and Chinese version of methodist health care system nurse caring instrument revised by the research group. The latter instrument consists of 12 dimensions. namely care coordination, competence, teaching/learning, emotional support, respect for individuality, physical comfort, availability, helping/trusting relationship, patient/family engagement, physical environment, spiritual environment and outcomes. Descriptive analysis was performed on the data collected by the questionnaires, and independent sample t-test and one-way ANOVA were used to analyze the influencing factors of patient satisfaction. Results:A total of 107 hospitals were selected for questionnaire survey, including 86 tertiary hospitals and 21 secondary hospitals, and 29 108 valid questionnaires were recovered. The patient satisfaction with nursing humanistic care scored (5.40±0.86); the top three dimensions were competence (5.50±0.89), emotional support (5.47±0.88) and helping/trusting relationship (5.46±0.86); the lowest scoring dimensions were teaching/learning (5.38±1.01), spiritual environment (5.36±1.04) and patient/family engagement (5.11±1.28). Differences with gender, age, marital status, child status, educational level, occupation, place of residence, economic region, per capita monthly income of the family, type of medical insurance, medical department visited and surgery or not presented significant differences on the patient satisfaction with nursing humanistic care scores ( P<0.05). Conclusions:The satisfaction of patients with hospital′s nursing humanistic care in China was at the middle to upper level. In the future, health education for patients should be strengthened, and a mode of family-engaged nursing humanistic care should be constructed in line with the Chinese cultural background. In the process of nursing services, the particularity of patient groups should be considered to better meet their needs.
