ABSTRACT
OBJECTIVE To investigate the inhibitory effects of Ginkgo biloba extract （GBE） on renal inflammation in diabetic nephropathy （DN） model mice， and its potential mechanism. METHODS KK/Ay mice were fed with high fat and high sugar to induce DN model. They were divided into model group， positive control group [metformin 200 mg/（kg·d）]， GBE low-dose and high-dose groups [100， 200 mg/（kg·d）]， with 6 mice in each group. Six C57BL/6J mice were fed with a regular diet as the control group. Administration groups were given relevant liquid intragastrically， control group and model group were given constant volume of normal saline intragastrically， once a day， for 8 consecutive weeks. The body weight， fasting blood glucose， 24-hour food intake， 24-hour urine output， monocyte chemoattractant protein-1 （MCP-1）， interleukin-12 （IL-12）， IL-10， advanced glycation end products （AGEs）， blood urea nitrogen （BUN） and serum creatinine （Scr） of mice were measured， and the ratio of bilateral kidneys to body weight was also calculated. The pathological injury and fibrotic changes of the renal cortex were observed， and the expressions of macrophage polarization marker proteins [type M1： inducible nitric oxide synthase （iNOS）； type M2： arginase-1 （Arg-1）] and AGEs-the receptor of advanced glycation end products （RAGE）/Ras homolog gene pharm_chenjing@163.com family member A （RhoA）/Rho-associated coiled-coil forming protein kinase （ROCK） signaling pathway-related proteins were determined in renal cortex. RESULTS Compared with the model group， the symptoms such as renal cortical hyperplasia， vacuoles， infiltration of inflammatory cells， and renal cortical fibrosis had been improved in GBE low-dose and high-dose groups； body weight， serum level of IL-10， the expression of Arg-1 in the renal cortex were significantly higher than model group （P＜ 0.01）； fasting blood glucose， 24-hour food intake， 24-hour urine output， serum levels of MCP-1， IL-12， BUN， Scr and AGEs， the ratio of bilateral kidneys to body weight， renal injury score， the proportion of renal interstitial fibrosis， the protein expressions of iNOS， RAGE， RhoA and ROCK1 （except for GBE low-dose group） in renal cortex were significantly lower than model group （P＜0.01）. CONCLUSIONS GBE could improve kidney damage and alleviate inflammatory response in DN model mice， the mechanism of which may be related to inhibiting the AGEs-RAGE/RhoA/ROCK signaling pathway and regulating macrophage polarization.
ABSTRACT
Coronary microvascular dysfunction （CMD） is one of the important causes of myocardial ischemia and non-obstructive coronary artery ischemic symptoms. However， effective diagnostic methods and targeted treatment strategies for CMD are currently lacking. According to traditional Chinese medicine （TCM）， the comorbidity theory of "blood-vessel-cardiac collaterals" plays a central role throughout the entire development process of CMD. It suggests that in the clinical diagnosis and treatment of CMD， the treatment of blood， vessels， and cardiac collaterals should not be neglected. In light of this， insect medicines， known for their efficacy in promoting blood circulation， resolving stasis， and alleviating spasms， hold promise as a potential treatment for CMD. However， there is currently no research or summary on the use of insect medicines for the treatment of CMD. Therefore， this article took the comorbidity theory of "blood-vessel-cardiac collaterals" as the starting point and divided the pathogenesis of CMD into five evolution stages： Beginning in the blood （changes in blood components and hemorheology）， progressing in the vessels （atheromatous plaque formation and unstable plaques）， occurring in the cardiac collaterals （microvascular endothelial damage and microvascular constriction and spasms）， ending in the cardiac collaterals （microvascular remodeling）， and resulting in energy metabolism disorders throughout the process， so as to explore the pathogenesis and evolution of CMD. In addition， based on the modern pharmacological research on insect medicines， this article discussed the clinical application of insect medicines in the treatment of CMD from four aspects： Promoting blood circulation and removing blood stasis to relieve vessels' obstruction， relieving spasms to alleviate pain， combating poison with poison to disperse stagnation， and tonifying cardiac collaterals to nourish the heart， which aims to provide a theoretical basis for the use of TCM in treating CMD， broaden the scope of medication， and improve clinical efficacy.
ABSTRACT
Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
ABSTRACT
Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.
ABSTRACT
Objective:To investigate the effects of acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation on quality of life in patients with stable chronic obstructive pulmonary disease (COPD).Methods:A total of 109 patients with stable COPD admitted to People's Hospital of Gaomi from March 2019 to May 2020 were included in this study. They were randomly divided into a control group ( n = 54) and an observation group ( n = 55). Both groups were given tiotropium bromide powder inhalation and acupoint application therapy ( Dazhui, Shenque, Feishu, Pishu, Shenshu and Zusanli). Chinese medicine ointment was applied in the observation group, but not in the control group. All patients were treated for 6 consecutive months. Before and after treatment, pulmonary function indicators [forced expiratory volume in the first second (FEV 1), the percentage of expiratory volume in the first second (FEV 1%), forced vital capacity (FVC), FEV 1/FVC], modified Medical Research Council (mMRC) dyspnea scale score, and the Saint George's Respiratory Questionnaire (SGRQ) score were compared between the two groups before and after treatment to evaluate therapeutic efficacy and quality of life. Results:Before and after treatment, there were no significant differences in FEV 1, FEV 1% and FEV 1/FVC between the two groups (all P > 0.05). After treatment, mMRC score and SGRQ total score in the observation group were (1.91 ± 0.27) points and (38.54 ± 8.18) points, respectively, which were significantly lower than (2.43 ± 0.33) points and (43.12 ± 7.86) points in the control group ( t = 4.93, 4.47, both P < 0.05). The number of exacerbations and the number of hospitalizations were (0.42 ± 0.09) times/6 months and (0.27 ± 0.05) times/6 months in the observation group and they were (0.69 ± 0.17) times/6 months and (0.47 ± 0.13) times/6 months in the control group. There were significant differences in these indices between the two groups ( t = 3.90, 3.85, P < 0.05). Conclusion:Acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation has a good therapeutic effect on stable COPD. The combined therapy can reduce the number of acute attacks and improve patient's quality of life. This study is scientific and innovative.
ABSTRACT
Objective:To study the epidemic characteristics of human brucellosis in Shandan County, Zhangye City, Gansu Province, and provide reference basis for formulating effective prevention and control measures.Methods:The surveillance data of brucellosis were collected from the China Disease Prevention and Control Information System and Shandan Center for Disease Control and Prevention to describe the three-compartment distribution (population, time, region distribution), and were analyzed by SPSS 19.0.Results:A total of 482 cases of brucellosis were reported with an average annual incidence of 48.99/100 000 from 2016 to 2021 in Shandan County, and farmers were the mainly occupation (84.85%, 409/482). The sex ratio of men and women was 3.16 ∶ 1.00 (366/116). The onset time was mainly concentrated in summer and autumn. Breeding cattle and sheep (feeding, cleaning pens, etc.) resulted in 107 cases of direct contact infection, accounting for 22.20% of the total cases (107/482). Incidence rate of different years was quite different (χ 2 = 121.09, P < 0.001). The average annual incidence rate of brucellosis in Laojun Township (95.72/100 000) was statistically different from that in other towns (χ 2 = 20.49, P < 0.001). Conclusions:The overall high prevalence of human brucellosis in Shandan County from 2016 to 2021. The animal husbandry department should strengthen the control of infectious sources, and the health department should increase publicity and education to curb the spread of the epidemic as soon as possible.

ABSTRACT
As an edible eukaryotic microorganism, Saccharomyces cerevisiae has the characteristics of high safety, rapid proliferation, low cost, easy transformation, etc. It has been widely used to produce vaccines, antibodies, insulin, etc. Up to now, yeast components, such as cell wall and yeast microcapsules, have been widely used in the treatment of tumors, inflammatory virus infection, post-traumatic osteoarthritis and other diseases. Among them, the components of yeast cell membrane are relatively simple and stable, which are easy to be extracted on a large scale. Therefore, yeast cell membrane material was used to construct yeast membrane vesicle nanosystem, and its biomedical application was preliminarily explored. In this study, Saccharomyces cerevisiae membrane vesicle (SMV) was prepared by co-extrusion method, and the particle size and surface potential of SMV, drug loading and release characteristics, stability, cell safety, and in vitro therapeutic effect were investigated. The results showed that the average particle size of SMV was 185.1 nm. Curcumin and silica nanoparticles were effectively encapsulated by co-incubation and ultrasonic methods, and the characteristics of cell membrane proteins were maintained. Moreover, SMV had good stability and biocompatibility. In addition, SMV could be effectively uptaken by macrophages RAW 264.7, and curcumin loaded SMV could effectively eliminate reactive oxygen species (ROS). In conclusion, the yeast plasma membrane vesicles prepared in this study could effectively deliver curcumin drugs and encapsulate nanoparticles, and could be effectively absorbed by macrophages and effectively eliminate ROS, providing new ideas and new methods for biomedical applications of yeast membrane materials.
ABSTRACT
Silicosis is a common occupational disease caused by long-term inhalation of large amounts of free SiO2 dust and deposition in lung tissues, characterized by the formation of silicon nodules and diffuse fibrosis of lung tissues. Silicosis is one of the most common and serious occupational diseases in China, and its treatment imposes a huge economic burden on individuals and the country. The formation mechanism of silicosis is very complex, and no early screening indicators, effective drugs, and treatment methods are available yet. The current diagnosis of silicosis is based on occupational history and chest radiography findings, and it is irreversible once pulmonary fibrosis develops. Moreover, as silicosis is a continuously progressive disease, even if silicosis patients stop exposure to free SiO2 dust, their pulmonary fibrosis will continue to develop and deteriorate. Programmed cell death (autophagy, apoptosis, ferroptosis, etc.) is a key factor involved in the development of silicosis. This article summarized the important roles of programmed cell death, including autophagy, apoptosis, and ferroptosis, in silicotic fibrosis, and concluded that regulating different programmed cell death and related signaling pathways through effective means may delay the process of silicosis fibrosis, providing new ideas and clues for exploring potential mechanisms of silicosis formation and formulating prevention and treatment strategies.
ABSTRACT
OBJECTIVE To evaluate the risk of hypoglycemia caused by sodium-glucose co-transporter protein 2 （SGLT-2） inhibitors in type 2 diabetes （T2DM） patients. METHODS Retrieved from PubMed， Web of Science， Cochrane Library， CNKI， VIP， Wanfang Data and CBM， randomized controlled trials （RCTs） about SGLT-2 inhibitors in the treatment of T2DM were collected from the inception to Oct. 15th， 2022. After literature screening， data extraction and quality evaluation of included literature with bias risk assessment tool recommended by the Cochrane system evaluator handbook 5.1.0， Stata 15.1 software was used for network meta-analysis and publication bias analysis. RESULTS A total of 22 RCTs were included， with a total of 18 734 patients. The results of meta-analysis showed that compared with ertugliflozin 15 mg [RR＝3.26， 95%CI （1.13， 8.11）， P＜0.05] and ertugliflozin 25 mg [RR＝3.08， 95%CI （1.12， 6.34）， P＜0.05]， the incidence of hypoglycemia was significantly increased in patients using canagliflozin 300 mg. Compared with ertugliflozin 15 mg [RR＝1.48， 95%CI （1.24， 6.93）， P＜0.05] and ertugliflozin 25 mg [RR＝6.74， 95%CI （1.33， 9.34）， P＜0.05]， the incidence of hypoglycemia in patients treated with canagliflozin 100 mg was significantly increased. There was no statistically significant difference between other groups （P＞0.05）. The ranking results of the network meta-analysis showed that the incidence of hypoglycemia was from low to high， ie. ertugliflozin 15 mg＞placebo＞ertugliflozin 25 mg＞empgaliflozin 25 mg＞empgaliflozin 10 mg＞empgaliflozin 1 mg＞dapagliflozin 5 mg＞ dapagliflozin 10 mg＞dapagliflozin 2.5 mg＞canagliflozin 300 mg＞ertugliflozin 10 mg＞ertugliflozin 5 mg＞empgaliflozin 50 mg＞canagliflozin 200 mg＞canagliflozin 100 mg＞canag-liflozin 50 mg＞ertugliflozin 1 mg＞empgaliflozin 5 mg. Results of publication bias analysis showed that there was little possibility of publication bias in this study. CONCLUSIONS When SGLT-2 inhibitors are used in patients with T2DM， the incidence of hypoglycemia is the lowest when using ertugliflozin 15 mg， and the incidence of hypoglycemia is the highest when using empagliflozin 5 mg.
ABSTRACT
OBJECTIVE To mine the adverse drug reaction （ADR） signals of melphalan， so as to provide reference for clinically safe drug use. METHODS Using OpenVigil 2.1 data platform， relative ADR reports of melphalan from the first quarter of 2004 to the second quarter of 2022 in FAERS database were collected； data mining was conducted using the reported odds ratio （ROR） method and Medicines and Healthcare Products Regulatory Agency （MHRA） method of disproportional method. ADR reports were described and classified according to the system organ class （SOC） and preferred term （PT） in Medical Dictionary for Regulatory Activities （24.0 edition）. RESULTS A total of 17 046 ADR reports related to the target drug melphalan were retrieved， and the number of ADR reports showed a fluctuating upward trend； the majority of patients were male （43.28%）， and were concentrated between the ages of 50-＜75 （35.09%）， with the main reporting country being the United States （23.97%）； ADR report involved a total of 22 842 severe outcomes， mainly including hospitalization or extended hospitalization （24.45%）. Totally 403 ADR signals were detected， involving 23 SOC， mainly including blood and lymphatic system diseases （801 cases， 13.77%）， followed by eye organ diseases （755 cases， 12.97%） and infectious and invasive diseases （716 cases， 12.30%）. The ADR signals ranked high in the number of reported cases included febrile neutropenia， diarrhea， fever and mucositis and other PT； PT such as pneumonia， sepsis， vitreous hemorrhage， chorioretinal atrophy， myelodysplastic syndrome were not recorded in drug instructions. The ADR signals with high signal strength ranking included choroidal dystrophy， chorioretinal atrophy， eyeball atrophy and other PT， and above three types of PT were not included in the drug instructions. CONCLUSIONS ADRs caused by melphalan mainly include blood and lymphatic system diseases， eye organ diseases， and infectious and invasive diseases； before using melphalan， it is necessary to evaluate the drug use of patients， and pay close attention to the patient’s blood indicators and eye toxicity reaction， so as to guarantee the safety of treatment.
ABSTRACT
With the improved understanding of driver mutations in non-small cell lung cancer (NSCLC), expanding the targeted therapeutic options improved the survival and safety. However, responses to these agents are commonly temporary and incomplete. Moreover, even patients with the same oncogenic driver gene can respond diversely to the same agent. Furthermore, the therapeutic role of immune-checkpoint inhibitors (ICIs) in oncogene-driven NSCLC remains unclear. Therefore, this review aimed to classify the management of NSCLC with driver mutations based on the gene subtype, concomitant mutation, and dynamic alternation. Then, we provide an overview of the resistant mechanism of target therapy occurring in targeted alternations ("target-dependent resistance") and in the parallel and downstream pathways ("target-independent resistance"). Thirdly, we discuss the effectiveness of ICIs for NSCLC with driver mutations and the combined therapeutic approaches that might reverse the immunosuppressive tumor immune microenvironment. Finally, we listed the emerging treatment strategies for the new oncogenic alternations, and proposed the perspective of NSCLC with driver mutations. This review will guide clinicians to design tailored treatments for NSCLC with driver mutations.

AIM: To explore the value of ocular trauma score(OTS), initial visual acuity, and ocular structural parameters in the assessment of healing visual acuity from ocular trauma.METHOD: A total of 302 cases(302 eyes)of ocular trauma were selected as subjects, which were accepted and issued clear appraisal opinions by the Academy of Forensic Science from June 2015 to June 2021. The subjects were grouped according to the healing best corrected visual acuity(BCVA)from ocular trauma. Group Ⅰ included 63 cases(63 eyes)with BCVA &#x003C;3.7; Group Ⅱ included 70 cases(70 eyes)with 3.7≤ BCVA &#x003C;4.5; Group Ⅲ included 78 cases(78 eyes)with 4.5≤ BCVA &#x003C;4.9; Group Ⅳ included 91 cases(91 eyes)with BCVA≥4.9. In addition, 77 cases(77 healthy eyes)of ocular trauma were selected as the control group, namely Group Ⅴ. The healing BCVA and ocular structural parameters from ocular trauma and theirs correlation were analyzed, and the random forest(RF)and support vector machine(SVM)model of healing visual acuity was established by the IBM SPSS Modeler 18.0.RESULTS: The initial visual acuity, OTS, the grading of corneas, lenses, and fundus, and the thickness of the retinal never fiber layer of ocular trauma patients were correlated with the healing BCVA(P&#x003C;0.01). There were significant differences in ocular structural parameters among groups, except the central subfield thickness(P&#x003C;0.001). The SVM model had higher accuracy of predicting healing visual acuity than the RF model, and the accuracy rate was over 80% when the error was within 0.15.CONCLUSION:OTS and ocular structural examination can provide effective information for the clinical forensic medicine appraisal of visual dysfunction after ocular trauma, and they are valuable in discriminating camouflage of visual dysfunction.
ABSTRACT
Objective To analyze the epidemiological characteristics of pulmonary tuberculosis in the elderly people in Wuhan during 2016-2020, and to provide a basis for formulating effective prevention and control strategies and measures. Methods Using the National Tuberculosis Information Management System, a descriptive statistical analysis was performed on the medical records of elderly (≥60 years old) pulmonary tuberculosis patients registered in Wuhan from 2016 to 2020. Results A total of 9 427 elderly pulmonary tuberculosis patients were registered in Wuhan during 2016-2020, accounting for 32.07% of the total number of registrations in the whole population. The reported incidence rate of tuberculosis in the elderly was significantly higher than that in the total population, and the reported incidence rates in both the elderly and the general population showed declining trends (whole population χ2trend=216.97, P2trend=153.57, P<0.05). The time distribution showed that more cases occurred from April to November (70.90%). The top three districts with the largest number of registered cases were far urban areas, namely Huangpi District (13.81%), Xinzhou District (11.55%), and Jiangxia District (9.82%). The ratio of male to female with pulmonary tuberculosis in elderly patients was 2.85:1. Among the elderly pulmonary tuberculosis, the most registered cases were in the age group of 60 ~ years old, followed by 65 ~ years old. The proportion of smear-positive in elderly patients with pulmonary tuberculosis retreatment was 16.83%. Conclusion From 2016 to 2020, the epidemic situation of elderly pulmonary tuberculosis showed a downward trend in Wuhan. However, the elderly population with tuberculosis registrations still accounted for a relatively high proportion of the total population. According to the epidemiological characteristics of pulmonary tuberculosis among the elderly, the city should carry out tuberculosis prevention and control work in a timely, appropriate and focused manner.
ABSTRACT
Objective:To study the risk factors and prognosis of pulmonary hypertension(PH) associated with bronchopulmonary dysplasia (BPD) in extremely preterm infants(EPIs).Methods:From January 2020 to December 2021, EPIs [gestational age (GA) <32 w] with BPD admitted to NICU of our hospital were retrospectively assigned into two groups: BPD with late-onset PH(PH group) and BPD without late-onset PH(non-PH group). Their general condition, treatment and prognosis were compared and the risk factors of late-onset PH were analyzed.Results:A total of 229 EPIs with BPD were enrolled, including 24(10.5%) in the PH group and 205(89.5%) in the non-PH group. The PH group had significantly smaller GA [(27.9±2.3) w vs. (28.7±1.8) w], longer mechanical ventilation [42.0(16.0, 84.0) d vs. 9.0(2.0, 23.0) d], longer hospital stay [100.5(86.3, 142.0) d vs. 77.0(56.5, 96.5)d],higher incidence of early-onset PH(54.2% vs. 9.3%) and higher mortality rate(33.3% vs. 9.8%) than the non-PH group ( P<0.05). Multivariate logistic regression analysis showed prolonged mechanical ventilation ( OR=1.046, 95% CI 1.011~1.064), early-onset PH ( OR=5.414, 95% CI 1.796~16.323) were independent risk factors for BPD with late-onset PH. 8(33.3%) patients in the PH group died, including 2 with grade Ⅱ BPD and 6 grade Ⅲ BPD. Conclusions:Prolonged mechanical ventilation and early-onset PH are independent risk factors for late-onset PH in BPD infants. BPD infants with late-onset PH have longer hospital stay, higher mortality and worse prognosis.
ABSTRACT
Objective:To investigate the application of extracorporeal membrane oxygenation(ECMO)bridging heart transplantation in critically ill children.Methods:The clinical data of two cases of critical infants with venous-arterial ECMO(VA-ECMO)bridging heart transplantation and literature review were retrospectively analyzed.Results:Two cases received orthotopic heart allograft with VA-ECMO support, and were discharged uneventfully without significant postoperative complications.On the 13th day of ECMO assistance, the first child was treated with orthotopic heart transplantation in a hospital qualified for heart transplantation, and the ECMO was evacuated during the operation.After 21 days of the heart transplantation, the patient was discharged from the hospital.The patient was followed up to be healthy after heart transplantation, and had the same development as children of the same age, and had been taking anti-rejection drugs for a long time.On the 10th day of VA-ECMO treatment, the second case received awake ECMO after cardiac function improved.On the 12th day of VA-ECMO treatment, the patient was successfully evacuated from VA-ECMO and waited for heart transplantation.Cardiac orthotopic transplantation was performed after the 17 days after VA-ECMO evacuation.The patient was transferred to the general ward after 6 days of hospitalization in the intensive care unit, and was discharged 23 days after transplantation with conventional anti-rejection therapy.Discharge follow-up in good health, normal school life.Conclusion:When VA-ECMO cannot be withdrawn from the heart of the critically ill children and the end-stage heart, VA-ECMO bridging heart transplantation should be selected at the right time for the children who meet the indications for heart transplantation to create survival opportunity for the previously hopeless children, save the life of the end-stage children, and improve the quality of life.
ABSTRACT
Objective:This study aimed to investigate the present status of professional identity in internship nursing students and to find the moderate role of mindfulness in the relationship between neuroticism and professional identity.Methods:This was a cross sectional investigation. From October to December 2021, 819 internship nursing students from four hospitals of Shandong Province were invited to participate in the study and to finish a questionnaire survey including the general information questionnaire, Professional Identity Questionnaire for Nurse Students (PIQNS), the Big Five Inventory(BFI) and Mindful Attention Awareness Scale (MAAS).Results:The average score of PIQNS was (61.41 ± 11.59). Pearson correlation analysis showed that professional identity was negatively associated with neuroticism ( r=-0.405, P<0.01) and positively associated with mindfulness ( r=0.301, P<0.01). Neuroticism was negatively associated with mindfulness ( r=-0.439, P<0.01). The hierarchical regression showed that mindfulness level could moderate the correlation between neuroticism and professional identity. Furthermore, the Johnson-Neyman technique revealed that the moderating role was significant only when the positive level was greater than 47.085. Conclusions:The professional identity of internship nursing students deserves attention. Mindfulness level could moderate the correlation between neuroticism and professional identity. It is suggested that clinical managers to carry out targeted training, to enhance the professional identity of internship nursing students during internship.

ABSTRACT
Cordyceps， a unique precious Chinese herbal medicine in China， has the effects of tonifying the kidney and lungs， stopping bleeding， and resolving phlegm. It has definite clinical effects on diabetes， respiratory diseases （such as chronic obstructive pulmonary disease）， chronic kidney diseases， slow arrhythmia， and hyperlipidemia. We searched China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SpringerLink （Biomedical Sciences）， Embase， Proquest （Life Sciences）， PubMed， Cochrane Library， and SinoMed for the research on the arsenic content in Cordyceps. According to statistical analysis， arsenic in Cordyceps mainly exists in the non-toxic or low-toxic form. The arsenic-containing compounds in Cordyceps may be an arsenic-sugar compound with anticancer effect. The inorganic arsenic content in Cordyceps is lower than the arsenic standard stipulated by the State Food and Drug Administration. It remains uncertain whether different measurement methods can affect the results. The total arsenic content varies in Cordyceps from different producing areas， and the general rule of total arsenic content in Cordyceps produced in different provinces， districts， and counties cannot be obtained from the results of the existing studies. The arsenic content in Cordyceps is mainly concentrated in the insect part， which is significantly different from that in stroma， and no arsenic is detected in the mycelia. The soil arsenic content in the growing areas is generally high， which may be a main reason for the high arsenic content in Cordyceps. As a valuable medicinal material for tonifying and nourishing， Cordyceps still plays an irreplaceable role in disease prevention， health care， chronic disease management， and rehabilitation.
