Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

MicroRNAs(miRNAs)comprise a class of endogenous RNA molecules with a typical length of 19～25 nucleotides.They regulate gene expression levels by identifying homologous sequences and intervening in transcription,translation,or epigenetic processes.miRNAs have potential applications in relation to the pathogenesis,progression,and treatment of deep vein thrombosis(DVT).DVT refers to the abnormal coagulation of blood within the lumen of the deep veins,blocking the venous lumen and obstructing the venous return,especially in the lower limbs.Furthermore,detachment of the thrombus and entry into the lungs can lead to death.This article comprehensively reviews recent research findings regarding the diverse mechanisms of action of miRNAs in relation to DVT.Given that the regulation of miRNA expression using targeted therapeutic approaches may promote the recovery of DVT,this article also discusses the potential applications of miRNAs for the clinical diagnosis and treatment of DVT,and aims to provide valuable references and insights for future clinical and basic research in the field of DVT.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

Objective:To investigate the clinical value of zoledronic acid in improving the prognosis of osteoporotic hip fracture and preventing its sequential contralateral hip fracture.Methods:A retrospective study of 206 patients diagnosed with hip fragile fractures in China Medical University Affiliated Shengjing Hospital and treated with anti-osteoporotic drugs after surgery was conducted. The prognosis of patients with hip fracture using survival rate analysis and the risk factors of acute febrile complications with multivariate analysis after zoledronic acid treatment were evaluated. Furthermore, chi-square test and multivariate analysis was used to explore whether zoledronic acid decreases the occurrence of the contralateral sequential fracture.Results:The 3-year survival rate of patients with overall hip fracture was higher in zoledronic acid treatment group compared with control group( P=0.026), with the incidence of fever at 53.3%. The age [ OR=0.786, P=0.027, the area under receiver operating characteristic (ROC) curve was 0.724] and cardiopulmonary complications ( OR=0.043, P=0.025, the area under ROC curve was 0.628) were significantly correlated with the occurrence of acute febrile response. The incidence of sequential contralateral fractures in zoledronic acid treatment group was significantly lower than that in control group ( χ2=4.356, P=0.037). The application of zoledronic acid ( OR=0.160, P=0.007, the area under ROC curve is 0.586) and the type of femoral neck fracture ( OR=0.196, P=0.001, the area under ROC curve is 0.607) were statistically associated with the occurrence of sequential fractures. Conclusion:Zoledronic acid treatment improves the outcome of patients with osteoporotic hip fracture and reduces the incidence of sequential hip fractures, especially femoral neck fracture. Senile age and cardiopulmonary complications might be associated with lower risk of acute febrile reactions after zoledronic acid treatment.

Objective:To explore and analyze the selection of surgical methods for supratentorial intracerebral hemorrhage.Methods:A total of 260 patients with spontaneous intracerebral hemorrhage who underwent surgery in Department of Neurosurgery, Suzhou Hospital Affiliated to Nanjing Medical University from January 2017 to December 2021 were included in the study by retrospective case analysis. According to different surgical methods, they were divided into three groups: large bone flap group ( n=116), conventional bone flap group( n=89)and stereotactic group( n=55). The large bone flap group underwent standard supratentorial large bone flap craniotomy, the conventional bone flap group underwent conventional bone flap craniotomy, and the stereotactic group underwent stereotactic hematoma puncture suction + drainage. Clinical indicators such as operation time, intraoperative bleeding, pulmonary infection, length of hospital stay, and Glasgow outcome scale (GOS) at 6 months of postoperative follow-up, and the proportion of good prognosis (GOS 4-5) were calculated. Measurement data with normal distribution were expressed as mean±standard deviation( ± s), count data were expressed as cases and percentages (%). Results:In the large bone flap group, the operation time, intraoperative bleeding, hospital stay, pulmonary infection, postoperative rebleeding were(193±24) min, (625±65) mL, (46±11) d, 102 patients(87%), 9 patients(7.8%), and (124±17) min, (297±35) mL, (32±9) d, 29 patients(33%), 4 patients(4.4%)in the conventional bone flap group, and (73±11) min, (53±15) mL, (21±4) d, 10 patients(18%), 2 patients(3.6%)in stereotactic group. All patients were followed up for 6 months, and 165 patients (63.5%) had good prognosis (GOS 4-5), including 36 patients (31%) in the large bone flap group, 82 patients (93.2%) in the conventional bone flap group, and 47 patients (85.5%) in the stereotactic group.Conclusion:Standard large craniectomy has sufficient effect of decompression, and is suitable for serious life threatening hematoma; Conventional craniotomy has advantages in the treatment of secondary intracerebral hemorrhage. Stereotactic surgery has the characteristics of short operation time, less intraoperative bleeding, short hospital stay and low incidence of pulmonary infection, which is worthy of promotion in the treatment of primary intracerebral hemorrhage.

Objective: To investigate the safety and efficacy of allogeneic CAR-T cells in the treatment of relapsed/refractory multiple myeloma (RRMM) . Methods: CAR-T cells were prepared from peripheral blood lymphocytes of HLA mismatch healthy donors. Median age was 55 (48-60) . Allogeneic cells were derived from 3 HLA haploidentical donors and 1 HLA completely mismatch unrelated donor. Four patients with RRMM were conditioned with FC regimen followed by CAR-T cell transfusion. They were infused into CART-19 (1×10⁷/kg on day 0) and (4.0-6.8) ×10⁷/kg CART-BCMA cells as split-dose infusions (40% on day 1 and 60% on day 2) . The adverse reactions and clinical efficacy were observed during follow-up after infusion, and the amplification and duration of CAR-T cells in vivo were monitored by PCR technique. Results: CAR-T cells were successfully infused in 3 of the 4 RRMM patients according to the study plan, and the infusion in one patient was delayed by 1 day due to high fever and elevated creatinine levels on day 3. The side effects included hematological and non-hematological toxicity, grade 3 hematological toxicity in 2 patients, grade 3 CRS in 1 one, grade 1 CRES in 1 one, prolonged APTT in 3 ones, tumor lysis syndrome in 1 one, mixed chimerism detected STR and clinical GVHD manifestation in 1 one. According to the efficacy criterias of IMWG, 2 patients acquired PR, 1 MR, and 1 SD respectively. Progression-free survival was 4 (3-5) weeks and overall survival was 63 (3-81) weeks. CAR T cells were amplified 2.2 (2-14) times in the patients with a median survival time of 10 (8-36) days. Conclusions Small sample studies suggested that GVHD may be present in the treatment of RRMM with allogeneic CAR-T cells. There were early clinical transient events after transfusion. Low amplification and short duration of CAR-T cells in vivo may be the main factors affecting the efficacy.

Objective: To explore the correlations relating functional MRI (fMRI) and diffusion tensor imaging (DTI) parameters with pre-operative neurological status and post-operative outcomes for patients with cervical spondylotic myelopathy (CSM). Methods: Eighty-seven CSM patients treated with surgical decompression and 38 healthy counterparts were enrolled as the CSM and control groups respectively. DTI and fMRI of the cervical spine were performed while the subjects performed a finger-tapping task with their right hands before the operation and 6 months later. The control group was evaluated only when they were enrolled. All of the patients were given systematic rehabilitation treatment after the surgery. The Japanese Orthopaedic Association (JOA) scoring system for CSM was used to evaluate neurological status, and a JOA recovery rate <50% was defined as a poor recovery. Results: Compared with the healthy controls, the pre-operative patients showed significantly higher volume of activation (VOA) in the left precentral gyrus (PrCG), but that had decreased significantly 6 months after the surgery. Before the surgery, the patients′ fractional isotropy (FA) was significantly less than that of the controls, but it had increased significantly 6 months after the operation. There was no difference in VOA in the left postcentral gyrus (PoCG) between the CSM patients and the controls before the surgery. The VOA ratio (PrCG/PoCG), VOA-PrCG, VOA-PoCG and FA were significantly correlated with both the JOA scores and recovery rates. Receiver operating characteristic (ROC) curve analyses were performed for the predictive ability with respect to surgical outcomes. The largest area under the ROC curve was observed for the VOA ratio (0.805), followed by FA (0.740), and the VOA-PrCG (0.715). The fMRI and DTI showed better potential for predicting functional outcomes than with standard MRI parameters. Multivariate logistic regression revealed that the VOA ratio and FA were independently associated with poor outcomes. Conclusions fMRI and DTI parameters may be more valuable than conventional MRI results for neurological assessment and prognosis with CSM patients. They can also provide references for making up rehabilitation plans.
