Objective To understand the application of skin disinfectant in neonatal intensive care units(NICUs)nationwide.Methods From April to May 2023,application of skin disinfectant in 93 NICUs nationwide was sur-veyed with convenience sampling method by a self-designed questionnaire.Questionnaire contents included types of disinfectant,disinfection tools,cleaning and disinfection frequency,disinfectant drying status,removal of disinfec-tant,and adverse reactions caused by disinfectant.Results A total of 93 nursing units in 71 medical institutions from 25 provinces/municipalities were included in this study.In NICUs,three most commonly used disinfectants were ethanol(79.57％),iodophor(74.19％),and anerdian(62.37％).In nursing units for neonates＜2 months of age,chlorhexidine was prohibited in 28 units(30.11％),used with caution in 23 units(24.73％),allowed in 9 units(9.68％),and there was no unified requirement in 33 units(35.48％).When using ethanol,staff only wiped once in 13(17.57％)nursing units.In some nursing units,there was no unified requirements on the wiping fre-quency of disinfectant.As for the removal of residual iodine,saline was used in 29(42.03％)nursing units,ethanol in 8(11.59％),and 19(27.54％)did not have unified requirements.The adverse reactions of disinfectant mainly included rash and contact dermatitis.Disinfectants that caused adverse reactions included ethanol,iodophor,aner-dian,and chlorhexidine.Conclusion In clinical practice,unified standards for the use of neonatal skin disinfectant remain absent.Selection and use of neonatal skin disinfectant vary considerably.Neonatal skin disinfectants have common adverse reactions.It is necessary to strengthen the training of health care workers on the standardized use of disinfectant,as well as carry out large-scale and rigorous randomized controlled trial designs to provide scientific basis for the correct selection of disinfectant.

Objective To observe the clinical effect of acupuncture combined with Shenqi Huoxue Decoction in the treatment of adenomyosis of qi deficiency and blood stasis type.Methods Seventy patients with adenomyosis of qi deficiency and blood stasis type were randomly divided into observation group and control group,35 cases in each group.The control group was treated with Levonorgestrel-releasing intrauterine system,and the observation group was treated with acupuncture combined with Shenqi Huoxue Decoction on the basis of the treatment of the control group.One menstrual cycle was a course of treatment,and the treatment lasted for three courses.After 3 months of treatment,the clinical efficacy of the two groups was evaluated,and the changes of Endometriosis Health Profile-5(EHP-5)score,serum superoxide dismutase(SOD)and catalase(CAT)were observed in the two groups before and after treatment.The changes of serum carbohydrate antigen CA125,carbohydrate antigen 199(CA199)and human epididymis protein 4(HE4)levels were compared before and after treatment between the two groups.Results(1)The total effective rate was 97.14％(34/35)in the observation group and 77.14％(27/35)in the control group.The clinical efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the levels of serum CA125,CA199 and HE4 in the two groups were significantly improved(P＜0.05),and the improvement of serum CA1 25,CA199 and HE4 levels in the observation group was significantly superior to that in the control group,the difference was statistically significant(P＜0.05).(3)After treatment,the levels of serum SOD and CAT in the two groups were significantly improved(P＜0.05),and the improvement of serum SOD and CAT levels in the observation group was significantly superior to that in the control group,the difference was statistically significant(P＜0.05).(4)After treatment,the EHP-5 score of quality of life in the two groups was significantly improved(P＜0.05),and the EHP-5 score of quality of life in the observation group was significantly superior to that in the control group,the difference was statistically significant(P＜0.05).Conclusion Acupuncture combined with Shenqi Huoxue Decoction in the treatment of adenomyosis of qi deficiency and blood stasis type can significantly improve the clinical symptoms of patients,regulate the levels of SOD and CAT,so as to improve the quality of life of patients,and the curative effect is significant.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To evaluate the efficacy of the combination of leonurine(SCM),polygonatum polysaccharide(PSP)and deoxynojirimycin(DNJ)in hypoglycemic and antithrombotic aspects by establishing and using zebrafish type II diabetes combined with thrombosis model. Methods On the basis of the zebrafish type II diabetes model established by streptozotocin,phenylhydrazine(PH),arachidonic acid(AA)and ponatinib(PT)were used respectively to establish thrombosis models,which were divided into control group,model group,metformin+aspirin group,and the high,medium and low concentration groups of the combination drugs. After drug intervention in the experimental group,the thrombosis of tail vein was observed. Kit was used to determine the sugar content of juvenile fish tissues in each group. Quantitative analysis of cardiac erythrocytes by o-dianisidine staining method was used to calculate the inhibition rate of thrombus. Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the mRNA expressions of related genes in zebrafish. Results Compared with the model group,the combined drug could significantly increase the staining intensity of erythrocytes in zebrafish hearts,inhibit thrombosis,down-regulate the expression of thrombosis-related genes,and reduce tissue glucose content. Conclusions The combined use of the three drugs can effectively reduce the tissue sugar content and have antithrombotic effect,which show great potential in the development of drugs for the treatment of type II diabetes and thrombosis.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Background: Synaptic plasticity contributes to nociceptive signal transmission and modulation, with calcium/ calmodulin-dependent protein kinase II (CaMK II) playing a fundamental role in neural plasticity. This research was conducted to investigate the role of CaMK II in the transmission and regulation of nociceptive information within the nucleus accumbens (NAc) of naïve and morphine-tolerant rats. Methods: Randall Selitto and hot-plate tests were utilized to measure the hindpaw withdrawal latencies (HWLs) in response to noxious mechanical and thermal stimuli. To induce chronic morphine tolerance, rats received intraperitoneal morphine injection twice per day for seven days. CaMK II expression and activity were assessed using western blotting. Results: Intra-NAc microinjection of autocamtide-2-related inhibitory peptide (AIP) induced an increase in HWLs in naïve rats in response to noxious thermal and mechanical stimuli. Moreover, the expression of the phosphorylated CaMK II (p-CaMK II) was significantly decreased as determined by western blotting. Chronic intraperitoneal injection of morphine resulted in significant morphine tolerance in rats on Day 7, and an increase of p-CaMK II expression in NAc in morphine-tolerant rats was observed. Furthermore, intra-NAc administration of AIP elicited significant antinociceptive responses in morphine-tolerant rats. In addition, compared with naïve rats, AIP induced stronger thermal antinociceptive effects of the same dose in rats exhibiting morphine tolerance. Conclusions This study shows that CaMK II in the NAc is involved in the transmission and regulation of nociception in naïve and morphine-tolerant rats.

Postoperative adhesion (PA) is currently one of the most unpleasant complications following surgical procedures. Researchers have developed several new strategies to alleviate the formation of PA to a great extent, but so far, no single measure or treatment can meet the expectations and requirements of clinical patients needing complete PA prevention. Chinese medicine (CM) has been widely used for thousands of years based on its remarkable efficacy and indispensable advantages CM treatments are gradually being accepted by modern medicine. Therefore, this review summarizes the formating process of PA and the efficacy and action mechanism of CM treatments, including their pharmacological effects, therapeutic mechanisms and advantages in PA prevention. We aim to improve the understanding of clinicians and researchers on CM prevention in the development of PA and promote the in-depth development and industrialization process of related drugs.
