Objective To investigate the influencing factors for neurological function recovery in patients with acute cerebral infarction(ACI)and type 2 diabetes mellitus(T2DM).Methods A total of 156 patients with ACI(ACI group)and 266 patients with T2DM combined with ACI(T2DM+ACI group)hospitalized in our hospital were enrolled in this study from December 2016 to February 2020.The recovery degree in two weeks was evaluated according to the modified Rankin scale(m-RS)score in T2DM combined with ACI.The T2DM+ACI group was further divided into a good subgroup with a score of<1(n=50)and a poor subgroup with a score of≥1(n=216).Clinical characteristics were compared between the two groups.Pearson correlation analysis was used to analyze the correlation between m-RS score and other indicators.Multiple linear regression analysis was used to analyze the influencing factors for m-RS score.Results The levels of FPG,HbA1c and TG were higher in T2DM+ACI group than in ACI group(P<0.05).The poor subgroup had significantly higher age and LP(a)than the good subgroup(P<0.05),and significantly lower LDL-C,TG,and serum uric acid than the good subgroup(P<0.05).Pearson correlation analysis showed that m-RS score was positively correlated with age,sex and LP(a)(r=0.227,0.170,0.157;P=0.000,0.005,0.011).Multiple linear regression analysis showed that age and LP(a)were the influencing factors for m-RS score.Conclusions LP(a)a is a influencing factor for neurological function recovery in patients with T2DM combined with ACI,and clinical attention should be paid to the level of LP(a)a in such patients.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the associated factors of depressive symptoms among patients with neo-plasms.Methods:Nationwide(excluding Hong Kong,Macao,and Taiwan),30 505 residents were selected by a combination of stratified sampling and quota sampling according to the proportion of the seventh national population census.Patient Health Questionnaire-9(PHQ-9),General Anxiety Disorder-7(GAD-7),self-made questionnaire,and simplified perceived social support scale used to evaluate depressive symptoms,anxiety symptoms,behaviors,and perceived social support among patients with neoplasms.Results:Totally 359(1.2％)patients with self-repor-ted clinically diagnosed neoplasms were included,of which 151(42.1％)patients with malignant neoplasms and 208(57.9％)patients with benign neoplasms.The detection rate of depressive symptoms in patients with neo-plasms was 76.6％.Less than three days of walking for more than 10 minutes per day in the past week(OR=6.63),4-6 days of walking for more than 10 minutes per day in the past week(OR=5.00),the low(OR=4.80)or medium(OR=3.06)overall sleep quality,the lower perceived friend support(OR=4.66),and anxiety symp-toms(OR=1.74)among patients with neoplasms were risk factors for depressive symptoms.Conclusion:Patients with neoplasms generally might be at a high risk of depressive symptoms,especially for those patients with less ex-ercise,poor sleep quality,and low perceived social support.

Objective To Investigate the effect of copper ions on the radiosensitivity of nasopharyngeal carcinoma(NPC)and identify potential targets to improve the efficacy of NPC radiation therapy.Methods The content of copper ions in normal nasopharyngeal epithelial cell line NP69 and a variety of NPC cell lines was detected by a copper microplate assay.After adding 0,5,10,20,50,100,200 μmol/L copper ion solution and 0,0.05,0.1,0.2,0.5,1.0,2.0 mmol/L TEPA solution,CCK-8 assay was used to determine the effect of intracellular copper ion content on the survival rate of NPC cells before and after irradiation.And determine the drug concentration to be used in subsequent experiments.CCK-8 assay was used to determine the effect of intracellular copper ion content on the survival rate of NPC cells before and after irradiation,and to determine the drug concentration used in the copper ion group and TEPA group in the subsequent experiments.CCK-8 assay and clone formation assay were used to detect the changes in radiosensitivity of NPC cells after drug treatment.The DNA damage and MAPK-ERK signaling pathway-related protein expression of NPC cells in each group before and after irradiation were detected by Western blot.Results The content of copper ions in NPC cells was significantly higher than that in normal naso-pharyngeal epithelial cells(P＜0.05).When the concentration of copper ion solution was lower than 50 μmol/L,the radiation resistance of CNE1 cells was improved,and the radiation sensitivity of SUNE1 cells was increased by 0.1～0.2 mmol/L TEPA(P＜0.05).Compared with the control group,the NPC cell radiotherapy resistance of copper ion group was enhanced,and the NPC cell radiotherapy sensitivity of copper ion group was enhanced(P＜0.05).Compared with the control group,the activation degree of MAPK-ERK pathway in copper ion group was up-regulated(P＜0.05).MAPK-ERK pathway inhibitor SCH772984 effectively reversed copper-mediated NPC radiotherapy resistance(P＜0.05).Conclusion The increased copper ion content in NPC cells promoted the radiotherapy resistance of NPC cells by activating the MAPK-ERK signaling pathway.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective:To observe the susceptibility factors of elderly patients with corynebacterium striata in sputum of lower respiratory tract and analyze its clinical therapeutic effect.Methods:The clinical data of 192 elderly inpatients infected with corynebacterium striatum detected in sputum of lower respiratory tract were retrospectively analyzed in Quanzhou First Hospital Affiliated to Fujian Medical University from January 2019 to June 2021.The detection rate of corynebacterium striata was calculated, and the susceptibility factors and clinical efficacy were compared between the infection group(n=102)and the colonization group(n=90).Results:The detection rate of corynebacterium striata(detected cases / numbers of qualified lower respiratory tract sputum specimen)was 0.8%(72/8976)from January to December 2019, 2.3%(134/5877)from January to December 2020, and 3.0%(121/4 039)from January to June 2021, the difference was statistically significant( χ2=93.93, P<0.01). The detection rates of corynebacterium striatum during three corresponding periods in elderly patients were 0.6%(57/8 976), 1.4%(81/5 877)and 1.9%(78/4 039), respectively, with statistically significant differences( χ2=45.57, P<0.01). The incidences or values of following indexes were higher in infection group than in colonization group: age of patients, admission of intensive care unit, malnutrition, use of hormones, combined use of antibiotics, use of invasive mechanical ventilation, use of fiber bronchoscope, reduced cough reflex, other basic diseases, and so on, but the differences were not statistically significant(all P>0.05). The clinical effective rates were 41.2%(42/102)in the infection group and 48.9%(44/90)in the colonization group, respectively, and the differences was not statistically significant( P>0.05). Only 25 patients(24.5%)in the infected group were treated on corynebacterium striatum according to drug sensitivity results.Among them, the clinical effective rate of the treatment group and the untreated group was 68.0%(17/25)and 32.5%(25/77), respectively, the difference was statistically significant( χ2=9.84, P<0.01). The clinical effective rate of untreated group was lower than that of colonization group, the difference was statistically significant( χ2=4.62, P<0.05). Conclusions:The detection rate of corynebacterium striatum in elderly patients is high, and increases year by year.Patients infected with corynebacterium striatum usually has a variety of susceptibility factors, if not taking effective treatment measures, may have adverse outcomes.In clinical work, it is necessary to pay attention to and reduce the susceptibility factors of corynebacterium striatum, and to correctly interpret the etiological reports, so as to adopt a reasonable and effective therapeutic schedule.

A new-type digital electric plum-blossom needle instrument of controllable and adjustable parameters was developed to achieve an automatic tapping instead of manual tapping technique and integrate the function of plum-blossom needle with that of micropulse electrical phase. The alternating current of periodic variation changes the direction of magnetic field around, induces the vibration of the cone head and tapping movement, outputs the micropulse current and acts on the affected area in treatment. The new-type digital electric plum-blossom needle instrument achieves the automatic tapping movement, precisely adjusts the stimulating strength and frequency according to diseases and integrates the tapping stimulation with pulse current to form circulation loop on the skin and intensify the therapeutic effects. This instrument is the big innovation of traditional plum-blossom needle. It is not only applicable for clinical treatment or family healthcare, but also for scientific research with the adoptable digital therapeutic parameters, which benefits the application and development of plum-blossom needle therapy.

Investigating the influence of acupuncture on cellular signal transduction is an efficient pathway to reveal the action mechanism of acupuncture on spinal cord injury (SCI). In this study, the experiment research literature regarding acupuncture for SCI during past 10 years was reviewed and analyzed. As a result, it was found that acupuncture could regulate the expression of the first intercellular messenger as well as the second signal molecules including cyclic adenosine monophosphate, cyclic guanosine monophosphate, Ca2+, nitric oxide to intervene the apoptotic signaling pathway, Rho/Rock signaling pathway, Wnt signaling pathway, MAPK signaling pathway, Notch signaling pathway, etc., which could improve regeneration and repair of SCI. In conclusion, in future researches more attention should be paid to the cellular signal transduction networks and different effects among various acupoint combinations and acupuncture modalities on cellular signal transduction, which have an essential role for revelation of clinical application rules and optimization of clinical treatment protocol.
