BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

The operating room is the core settings of various surgical treatments, and exhibits distinct attributes and systemic complexities. Medical staff who work long term in operating rooms face multiple exposures to potential health hazards. Especially with the progress of electrosurgical technology and the frequent use of electrosurgical equipment, the possible health effects of the resulting electrosurgical smoke to those working in operating rooms have gradually attracted attention. This paper reviewed the composition, hazard, exposure risk monitoring, and protective measures of electrosurgical smoke, aiming to deepen the understandings of potential health risks of electrosurgical smoke, improve the self-protection awareness of medical staff, strengthen attention to electrosurgical smoke protection in all hospitals, and ensure the occupational safety of medical staff.

High-performance phototheranostics with combined photothermal therapy and photoacoustic imaging have been considered promising approaches for efficient cancer diagnosis and treatment. However, developing phototheranostic materials with efficient photothermal conversion efficiency (PCE), especially over the second near-infrared window (NIR-II, 1000-1700 nm), remains challenging. Herein, we report an ultraefficient NIR-II-activated nanomedicine with phototheranostic and vaccination capability for highly efficient in vivo tumor elimination and metastasis inhibition. The NIR-II nanomedicine of a semiconducting biradical oligomer with a motor-flexible design was demonstrated with a record-breaking PCE of 87% upon NIR-II excitation. This nanomedicine inherently features extraordinary photothermal stability, good biocompatibility, and excellent photoacoustic performance, contributing to high-contrast photoacoustic imaging in living mice and high-performance photothermal elimination of tumors. Moreover, a whole-cell vaccine based on a NIR-II nanomedicine with NIR-II-activated performance was further designed to remotely activate the antitumor immunologic memory and effectively inhibit tumor occurrence and metastasis in vivo, with good biosafety. Thus, this work paves a new avenue for designing NIR-II active semiconducting biradical materials as a promising theranostics platform and further promotes the development of NIR-II nanomedicine for personalized cancer treatment.

Objective To determine the acute effects of blood flow restriction(BFR)running warm-up on Achilles tendon morphology and function in basketball players in order to provide a theoretical basis for optimizing warm-up protocols for military personnel and athletes susceptible to Achilles tendon injuries.Methods Twenty-seven male basketball players were subjected and asked to participate in 3 different running warm-up protocols:low-speed running(LSR),high-speed running(HSR),and BFR combined with LSR(BFR-LSR).The acute changes in Achilles tendon morphology,mechanical properties,and functional performance across the 3 testing sessions were analyzed and compared.Results Immediately after training,both HSR warm-up and BFR-LSR warm-up significantly improved Achilles tendon thickness,blood flow,stiffness,and gastrocnemius maximal voluntary isometric contraction(MVIC)when compared with LSR warm-up(P<0.05).No statistical differences were observed in above indicators between the BFR-LSR and HSR warm-ups(P>0.05).24 hours after training,compared with LSR warm-up,HSR warm-up still significantly improved Achilles tendon thickness,blood flow,stiffness,and gastrocnemius MVIC(P<0.05).Although BFR-LSR warm-up did not show statistically significant differences in these parameters compared to LSR warm-up,it still demonstrated positive trends.Immediately and 24 h after training,no obvious difference were found in jump performance among the 3 warm-up protocols(P>0.05),but,both BFR-LSR and HSR warm-ups exhibited superior performance than LSR warm-up.Conclusion Immediately after training,BFR-LSR warm-up demonstrates comparable effects to the HSR warm-up on improving Achilles tendon morphology and performance,as well as enhancing jump performance.However,its sustained and long-term effects require further investigation.

Alzheimer's disease(AD)is a progressive neurodegenerative disease with hidden onset.Recent researches have shown that apolipoprotein E4(APOE4)is a high-risk genetic factor of AD,and the clinical symptoms in APOE4 genotype AD patients are closely related to metabolic disorders.This paper reviewed the role of APOE4 in the pathogenesis of AD,and it is indicated that APOE4 contributes to the injury of the cerebral blood-brain barrier,is associated with the disorder of cerebral glucose and lipid metabolism,and leads to the damage of the scavenging ability of microglia.Moreover,this paper explored the approach of early intervention of AD with traditional Chinese medicine(TCM)based on the APOE4 pathogenesis.Based on the pathogenesis of AD being deficiency in origin and excess in superficiality,and under the guidance of the principle of prevention before illness in TCM,it is proposed that early TCM intervention for APOE4 genotype AD patients with metabolic disorders can be performed through improving the phlegm-dampness constitution,by focusing on insulin resistance-related indicators,and with traditional Chinese drug therapy based on syndrome differentiation alone or together with comprehensive management of exercises,diet control and drug interventions,thus to reduce or delay the onset of APOE4 genotype AD.

Objective:To investigate the effect of preoperative old muscular calf vein thrombosis on the safety and efficacy of total knee arthroplasty (TKA).Methods:A total of 411 patients with end-stage knee osteoarthritis who underwent primary TKA in the First Affiliated Hospital of Nanjing Medical University from September 2021 to March 2023 were retrospectively analyzed. There were 89 males and 322 females, aged 68.05±5.91 years (range, 50-82 years). The body mass index was 26.8±3.7 kg/m 2 (range, 17.4-39.8 kg/m 2). The group was divided into a preoperative thrombosis group (47 cases) and a preoperative none-thrombosis group (364 cases) according to whether or not there was a combination of old muscular calf vein thrombosis before TKA. The clinical characteristics (location and size) and lower limb swelling were observed, and the American Knee Society (AKS) score, visual analogue scale (VAS) and Villalta score were recorded to compare the differences between the two groups. Results:All patients successfully completed the operation and were followed up for 7.4±1.1 months (range, 6-9 months). Postoperative deep venous thrombosis (DVT) occurred in 96% (45/47) of the patients in the preoperative thrombus group, which was greater than the 38.5% (140/364) in the preoperative none-thrombus group, and the difference was statistically significant (χ 2=55.184, P<0.001). 29% (13/45) of the patients who developed DVT postoperatively in the preoperative thrombus group had DVT located in the main vein, which was greater than the 9% (12/140) in the preoperative none-thrombus group, and the difference was statistically significant (χ 2=12.028, P<0.001). 51% (23/45) of patients with DVT after operation had thrombosis ≥6 mm, which was higher than 34% (47/140) of patients in the preoperative none-thrombus group, and the difference was statistically significant (χ 2=4.454, P=0.035). The rate of thigh swelling on postoperative day 3 was 8.42%±3.50% in the group with preoperative thrombus and 7.80%±4.12% in the preoperative none-thrombus group, and the differences were not statistically significant ( t=-0.995, P=0.320). The rate of calf swelling on postoperative day 3 was 8.14%±3.40% in the preoperative thrombus group, which was greater than the 5.51%±3.45% in the preoperative none-thrombus group, and the difference was statistically significant ( t=-4.923, P<0.001). Postoperative AKS scores were elevated in both groups and were greater than preoperative scores at 3 and 6 months postoperatively, with statistically significant differences ( P<0.05). There was no significant difference in AKS score between the two groups before operation ( P>0.05), and the AKS scores in the preoperative thrombus group were smaller than those in the preoperative none-thrombus group at 3 and 6 months postoperatively, with a statistically significant difference ( P<0.05). Postoperative VAS scores were reduced in both groups and were smaller than preoperative scores at 3 and 6 months postoperatively, with statistically significant differences ( P<0.05). There was no significant difference in preoperative VAS scores between the two groups ( P<0.05), and the VAS scores in the preoperative thrombus group were greater than those in the preoperative none-thrombus group at 3 and 6 months postoperatively, with a statistically significant difference ( P<0.05). The Villalta score of patients with DVT after operation in the preoperative thrombus group was 4.47±2.47 at the last follow-up, which was greater than that of the preoperative none-thrombus group, which was 2.90±1.92, and the difference was statistically significant ( t=-4.395, P<0.001). Conclusion:Preoperative combined old muscular calf vein thrombosis increases the incidence of postoperative DVT and the dangerousness of DVT is higher.

Objective To investigate the effect of blood flow restriction combined with low-intensity plyometric jump training(LI-PJT+BFR)on lower limb dynamic postural control of functional ankle instability(FAI)in college students. Methods From March to May,2023,40 FAI college students were recruited from Xi'an Physical Education University,and randomly divided into high-intensity plyometric jump training(HI-PJT,n = 14)group,low-intensity plyomet-ric jump training(LI-PJT,n = 13)group and LI-PJT+BFR group(n = 13).All the groups finished the six-week corresponding training.The maximum voluntary isometric contraction(MVIC)of tibialis anterior,peroneus lon-gus,lateral head of gastrocnemius,gluteus maximus,vastus lateralis,biceps femoris and semitendinosus were measured,and the root mean square(RMS)of electromyography of these muscles was measured during the sin-gle-leg landing(SLL),using wireless surface electromyography before and after intervention.Moreover,they were assessed with Y-balance test and Cumberland Ankle Instability Tool(CAIT). Results MVIC and RMS of the target muscles improved after intervention in all the groups(t>2.218,P<0.05),except MVIC and RMS of peroneus longus,gluteus maximus,biceps femoris and semitendinosus in LI-PJT group,and RMS of peroneus longus in LI-PJT+BFR group;and MVIC and RMS of the target muscles were the least in LI-PJT group(F>3.262,P<0.05),except those of peroneus longus.The extension scores of Y-balance test and the total score improved after intervention(t>2.485,P<0.05),and they were the least in LI-PJT group(F>5.042,P<0.05).The CAIT score improved after intervention(t>5.227,P<0.001),and it was the least in LI-PJT group(F = 4.640,P<0.05). Conclusion LI-PJT+BFR could improve lower limb dynamic postural control of FAI college students,which is similar to HI-PJT.

The full implementation of the dean's responsibility system under the leadership of the Party Committee trans-forms the hospital's Party Committee from its past role as the"political core"to the"leadership core".In the process of hospital management transformation,establishing a collaborative governance system between the Party and the government is key to imple-menting the dean's responsibility system under the leadership of the Party Committee.Taking the exploratory practices of Shenz-hen Hospital,Beijing University of Chinese Medicine(Longgang)as an example,this involves a comprehensive summary from improving decision-making mechanisms,leveraging the combat fortification role of Party branches and the exemplary role of Party members,and continuously expanding the service coverage of Party-building efforts.This discussion aims to explore effective im-plementation strategies for the dean's responsibility system under Party Committee leadership,to promote high-quality develop-ment of hospitals,and to provide meaningful references for the implementation of this system in public hospitals.

Seizures are a prevalent clinical manifestation during the neonatal period.The majority of neonatal seizures are transient symptoms caused by acute lesions，but in a few cases they are developmental epileptic encephalopathy with neonatal onset.Continuous video-EEG monitoring is the gold standard for diagnosing seizures in newborns,and complex seizures require comprehensive judgment using multi-channel monitoring such as synchronized EMG,blood oxygen,ECG,and respiratory monitoring.In 2021,the International League Against Epilepsy (ILAE) published the updated guidelines for the classification of neonatal seizures,proposing that neonatal seizures cannot be diagnosed if there is only clinical seizure without EEG evidence.Instead,they should be categorized into two types based on the presence of clinical movements and the characteristics of EEG changes during the seizure: electroclinical seizures and electrical seizures.Electroclinical seizures are categorized into motor seizures,non-motor seizures,sequential seizures,and unclassified seizures based on the symptoms exhibited during an attack.In 2023,the ILAE developed evidence-based recommendations for the management of antiseizure medications,discussed the treatment of neonatal seizures based on the latest evidence and emphasized the importance of video EEG in the treatment of neonatal seizures.Phenobarbital remains the first-line antiseizure medication,with phenytoin,levetiracetam,midazolam,or lidocaine as second-line agents.Pyridoxine should be considered for the treatment of neonatal seizures when first- and second-line drugs are ineffective.
