ObjectiveTo investigate the alleviating effect of calcium cyanamide （CaCN₂） soil fumigation on replanting problems of Rehmannia glutinosa. MethodsNewly soil （NP） was used as the control group， while three treatment groups were established： replanted soil （RP）， newly soil treated with CaCN₂ （120 g·m²， tillage depth 25 cm） （NPCC）， and replanted soil treated with CaCN₂ （RPCC）. R. glutinosa was cultivated in all groups. At harvest， the tuber agronomic traits （number of enlarged roots， maximum root diameter， fresh weight， dry weight） were measured. The content of catalpol and rehmannioside D was quantified by ultra-high-performance liquid chromatography （UPLC） to evaluate medicinal quality. Rhizosphere soil available nutrients and enzyme activities were analyzed by assay kits. The community structure and composition of fungi and bacteria in rhizosphere soil were assessed via internal transcribed spacer 2 （ITS2） sequencing and 16S rDNA sequencing， respectively. ResultsCompared with NP， the RP group showed obviously reduced in tuber agronomic traits and quality indicators （P0.05）. However， the RPCC group showed significant improvement in agronomic traits and a notable increase in rehmannioside D content compared to RP （P0.05）. The contents of available phosphorus and potassium in RPCC and NP groups were obviously lower than those in RP （P0.05）. The polyphenol oxidase soil （S-PPO） activity in RP was obviously lower than in NP （P0.05）， while sucrose soil （S-SC）， acid phosphatase soil （S-ACP）， and S-PPO activities in RPCC were obviously higher than in RP （P0.05）. Microbial richness and diversity in RP were obviously higher than in NP （P0.05）， whereas no significant differences were observed between the RPCC and NP. The relative abundances of fungal genera Nectria， Myrothecium， Tomentella， and bacterial genus Skermanella were obviousl lower in RPCC and NP than in RP （P0.05）. Correlation analysis that S-ACP activity was positively correlated with the content of rehmannioside D （P0.05）. Fungal genera Engyodontium and Alternaria， and bacterial genera Pir4 lineage， Pirellula， Methyloversatilis， Brevundimonas， Ralstonia， and Acidibacter were obviously positively correlated with tuber dry weight （P0.05）. Conversely， fungal genera Pseudaleuria， Nectria， Haematonectria， Ceratobasidium， and bacterial genera Streptomyces， Skermanella， RB41， Gemmatimonas， and Bacillus were obviously negatively correlated with dry weight （P0.05）. The fungal genus Alternaria and bacterial genera Brevundimonas， Ralstonia， Acidibacter， and Dongia showed positive correlations with medicinal quality of R.glutinosa tuber， while fungal genera Pseudaleuria， Nectria， Stachybotrys， Fusarium， Gibberella， Ceratobasidium， and bacterial genera Sphingomonas， Skermanella， RB41， Gemmatimonas， and Bacillus were obviously negatively correlated （P0.05）. ConclusionCaCN₂ soil fumigation can significantly improve enzyme activities in replanted Rehmannia rhizosphere soil， enhance the utilization of available nutrients， reshape microbial community structure of replanted R.glutinosa at the family and genus level， and notably improve tuber agronomic traits and medicinal quality. This study provides a novel approach to alleviating replanting problems and offers insights for the integrated development of standardized cultivation techniques， including soil disinfection， nutrient-targeted regulation， and microbial inoculant application.

Objective To observe the clinical efficacy of thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets in treating patients with severe cancer pain caused by malignant tumors.Methods A total of 60 patients diagnosed with severe cancer pain who were admitted to the Traditional Chinese Medicine Department of Qingpu Branch,Zhongshan Hospital Affiliated to Fudan University between November 2023 and December 2024 were selected as study subjects.Patients were randomly divided into an observation group and a control group using a random number table,with 30 cases in each group.The control group received conventional western medicine pain management,while the observation group received additional thumb-tack needling therapy based on the control group's treatment.The treatment duration was 2 weeks.After treatment,clinical efficacy was evaluated by observing changes in European Quality of Life-5 Dimensions(EQ-5D)scores,Numerical Rating Scale(NRS)scores,Cancer Pain Self-Efficacy Scale(CPSS)scores,and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30)scores in both groups before and after treatment.Changes in serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were also compared.Safety and adverse reactions were assessed.Results(1)The total analgesic effective rate was 76.67％(23/30)in the observation group and 46.67％(14/30)in the control group.The total effective rate in the observation group was significantly higher than that in the control group,with a statistically significant difference(P＜0.05).(2)After treatment,serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,EQ-5D scores,NRS scores,and CPSS scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,EORTC QLQ-C30 scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(5)The incidence of adverse reactions was 53.33％(16/30)in the observation group and 83.33％(25/30)in the control group.The incidence of adverse reactions in the observation group was significantly lower than that in the control group,with a statistically significant difference(P＜0.05).Conclusion Thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets significantly alleviates pain symptoms,improves health status and self-efficacy,and enhances the quality of life in patients with severe cancer pain caused by malignant tumors.

Hepatocellular carcinoma(HCC)expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming.Aldolase A(ALDOA)plays a prominent role in glycolysis;however,little is known about its role in HCC development.In the present study,we aim to explore how ALDOA is involved in HCC proliferation.HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout,which is consistent with ALDOA overexpression encouraging HCC prolifera-tion.Mechanistically,ALDOA knockout partially limits the glycolytic flux in HCC cells.Meanwhile,ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase;ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function.A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun,and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells.In HCC patients,the expression level of ALDOA was correlated with the phosphorylation level of c-Jun(Thr93)and poor prognosis.Remarkably,hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models,and the knockdown of Aldoa strikingly decreased HCC development in vivo.Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription,opening additional avenues for anti-cancer therapies.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

【Objective】 To analyze the situation of regular whole blood donation in Tianjin between 2013 and 2022, in order to provide data support for improving the recruitment and retention measures of regular blood donors and ensuring safe clinical blood supply. 【Methods】 From 2013 to 2022, 185 639 regular whole blood donors in Tianjin were selected as the study group and 1 015 312 other whole blood donors in the same period were selected as the control group. The demographic data, blood collection volume and blood retest screening of blood donors in the two groups were statistically analyzed. 【Results】 The number of regular blood donors and the volume of blood donated in Tianjin increased year by year from 2013 to 2022, with an average annual growth rate of 6.22% and 6.18%, respectively. From 2013 to 2021, the retention rate of regular blood donors increased first and then decreased. The proportion of male blood donors in the study and control groups showed a decreasing trend but the proportion of female donors showed an increasing trend, with the proportion of male donors in the study group higher than that in the control group and the proportion of female donors lower than that in the control group (both P<0.05). In the study group, the majority of blood donors were in the age of 26-35 years old, followed by those of 36-45 years old; in the control group, the majority of blood donors were in the age of 18-25 years old, followed by those of 26-35 years old; the proportion of blood donors in the study group in the age of 18-25 years old was lower than that in the control group, while the proportion of blood donors of other age group was higher than that in the control group, and the difference was statistically significant (P<0.05). The rates of 200 mL and 300 mL blood donations and insufficient blood donations in the study group were lower than those in the control group, while the rate of 400 mL blood donations was higher than that in the control group, and the differences were statistically significant. Among the blood donors in the study group, the proportion of students, civil servants, medical workers, military personnel, teachers and others was lower than that of the control group, while the proportion of the rest occupations was higher in the study group than that of the control group, and the differences were all statistically significant. There was a significant difference in the proportion of regular blood donors among blood donors of different professions. The re-test deferral rates of ALT and anti-TP in the study group showed a decreasing trend followed by an increasing trend, and the re-test deferral rates of HBV, HCV and HIV showed an increasing trend followed by a decreasing trend, and all the re-test deferral rates in the study group were lower than those in the control group, and the differences were statistically significant (P<0.05) . 【Conclusion】 From 2013 to 2022, the situation of regular blood donors in Tianjin has a certain regularity, and there is certain room for growth. Precise recruitment strategies targeting different populations should be adopted to have more regular blood donors.

Objective:To evaluate the clinical efficacy of nasal pedicle tissue flap based on nasal blood supply in the reconstruction of nasal skull base defects.Methods:A retrospective analysis was conducted on 138 clinical cases of skull base tumors and cerebrospinal fluid rhinorrhea treated at the Department of Otolaryngology, Head and Neck Surgery at Xiangya Hospital of Central South University from March 2017 to March 2023. A total of 79 males and 59 females were enrolled, aged from 8 to 82 years, with a median age of 51 years, including 108 patients (78.3%) with skull base tumors and 30 patients (21.7%) with cerebrospinal fluid rhinorrhea (and/or meningoencephalocele). During the surgery, 88 cases (63.8%) were repaired with nasal septal mucosal flaps pedicled with the posterior nasal septal artery, 14 cases (10.1%) with mucosal flaps pedicled with the anterior ethmoidal artery on the lateral wall of the nasal cavity, 6 cases (4.3%) with mucosal flaps pedicled with the posterior lateral nasal artery on the lateral wall and nasal floor, 12 cases (8.7%) with mucosal flaps pedicled with the anterior ethmoidal artery and posterior ethmoidal artery, and 18 cases (13.0%) with nasal septal mucosal extension flaps pedicled with the sphenopalatine artery or internal maxillary artery. Patients were followed up for 12 to 72 months postoperatively. Endoscopic examination or skull base enhanced MRI was performed to assess the growth and tumor recurrence in the skull base repair area. The t-test was used for statistical analysis.Results:Among 138 patients, primary repair was successful in 133 patients (96.4%), while 5 patients (3.6%) experienced postoperative cerebrospinal fluid rhinorrhea. These 5 patients all underwent nasal septal mucosal flap repair with the posterior nasal septal artery as the pedicle. Complications included 1 case of mucosal flap necrosis, 1 case of mucosal flap central perforation, and 3 cases of mucosal flap survival peripheral leakage, of which were all successfully treated with a second repair.Conclusion:The use of nasal pedicle mucosal flap based on nasal blood supply is a reliable, safe, and effective technique for repairing skull base defects.
