Objective:To investigate the correlation between emotional regulation self-efficacy and emotional intelligence among nurses.Methods:Totally 12 892 in-service nurses from 27 hospitals in Hunan Province were selected by convenience sampling from July to September 2021. Data were collected using a General Information Questionnaire, the Emotional Intelligence Scale (EIS), and the Regulatory Emotional Self-Efficacy Scale (RES). Univariate analysis was employed to explore the factors influencing nurses' emotional intelligence, and Pearson correlation analysis was used to examine the relationship between emotional regulation self-efficacy and emotional intelligence.Results:A total of 12 892 questionnaires were distributed, with 188 discarded due to incomplete or refused responses, resulting in 12 704 valid responses and an effective response rate of 98.54%. The total EIS score among the 12 704 nurses was (122.35±20.23), and the total RES score was (48.84±13.32). Correlation analysis indicated a positive correlation between emotional regulation self-efficacy and emotional intelligence ( P<0.01) . Conclusions:Nursing managers need to prioritize enhancing nurses' emotional regulation self-efficacy and emotional intelligence. Training should focus on aspects such as emotional cognition, emotional recognition, emotional regulation methods and strategies, and self-awareness development.

Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients, but currently available treatments are often ineffective. Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed. Rhodojaponin VI, a grayanotoxin from Rhododendron molle, showed remarkable antinociceptive efficacy in models of neuropathic pain, but its biotargets and mechanisms are unknown. Given the reversible action of rhodojaponin VI and the narrow range over which its structure can be modified, we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin VI. N-Ethylmaleimide-sensitive fusion (NSF) was confirmed as the key target of rhodojaponin VI through biological and biophysical experiments. Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca²⁺ current intensity, whereas rhodojaponin VI reversed the effects of NSF. In conclusion, rhodojaponin VI represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF.

ObjectiveTo study the correlation between Vimentin and hepatocellular carcinoma （HCC） and the mechanism of Jianpi Yiqi prescription against HCC through Vimentin. MethodCorrelation between Vimentin and HCC was analyzed based on the cancer genome atlas（TCGA）， clinical proteomic tumor analysis consortium（CPTAC）， STRING， and Cytoscape. SD rats were randomized into normal group （normal saline， ig， once/day， 4 weeks）， model group （normal saline， ig， once/day， 4 weeks）， low-dose， medium-dose， and high-dose （5.25， 10.5， 21 g·kg^-1， ig， once/day， 4 weeks） JianpiYiqi prescription groups， signal transducer and activator of transcription 3 （STAT3） inhibition group （C188-9， 4.5 mg·kg^-1， ip， once/day， 4 weeks）， and glycoprotein 130 （gp130） inhibition group （SC144， 4.5 mg·kg^-1， ip， once/day， 4 weeks）， 10 rats in each group. Diethylnitrosamine （DEN， 70 mg·kg^-1 body weight， ip） was injected in rats except the normal group to induce HCC. After the modeling， administration began. After last administration， Real-time polymerase chain reaction（Real-time PCR） was performed to determine Vimentin mRNA level in rat liver tissue. Caspase-3 activity in liver tissue was detected by colorimetry， and expression of Rho kinase （ROCK）1， ROCK2， aurora kinase B （AURKB）， Zinc-finger protein 148 （ZNF148）/zinc-binding protein-89 （ZBP-89）， STAT3， p-STAT3， total Vimentin， and phosphorylated （p）-Vimentin in liver tissue and Vimentin in liver tissue nucleus detected by Western blot. Serum Vimentin concentration was measured by enzyme-linked immunosorbent assay （ELISA）. ResultVimentin mRNA level was high in tissues from HCC patients with different cancer stages （stage Ⅰ-Ⅳ）， different pathological grades （G₁-G₃）， no regional lymph node metastasis （N0）， and different subtypes （P<0.01）. Vimentin mRNA expression was higher in tissues from patients with lymph node metastasis than in patients without lymph node metastasis and normal samples. Vimentin protein level was decreased in HCC tissues （P<0.01）. Vimentin gene has 4 mutations which can induce change in the primary structure of Vimentin protein and patients with Vimentin gene mutation had short disease free survival time （P<0.01）. The mRNA expression of Vimentin was negatively associated with HCC cell purity （P<0.01） but was positively associated with the infiltration levels of cancer-associated fibroblasts， M2 macrophages， myeloid dendritic cell and other immune cells in tumor microenvironment （P<0.01）. Association analysis results showed that the expression of Vimentin was correlated with the STAT3 expression in HCC tissues （P<0.01）. As for the animal experiment， Vimentin mRNA level and protein levels of total Vimentin and p-Vimentin in liver tssue， Vimentin protein level in liver tissue nucleus， Vimentin in rat serum， ROCK2， AURKB， STAT3 and p-STAT3 in liver tissues were up-regulated （P<0.01） and protein level of negative regulator ZBP-89 was reduced in the model group （P<0.01） compared with those in the normal group. Activity of Caspase-3 in liver tissue increased and the ROCK1 protein level was increased in the model group compared with those in the normal group. STAT3 inhibitor， gp130 inhibitor， and medium-dose and high-dose Jianpi Yiqi prescription all can reduce the secretory Vimentin protein in serum， protein levels of total Vimentin and p-Vimentin in liver tissues， and Vimentin in liver tissue nucleus， and the protein levels of STAT3/Vimentin signaling pathway-related molecules， such as STAT3， p-STAT3， ROCK2， and AURKB and up-regulate the protein level of negative regulator ZBP-89 and activity of Caspase-3 （P<0.05， P<0.01）. Effect of medium-dose or high-dose Jianpi Yiqi prescription on Vimentin mRNA expression， STAT3 protein expression， ZBP-89 protein expression， ROCK2 protein expression， AURKB protein expression and Caspase-3 activity was not significantly different from that of STAT3 inhibitor. ConclusionVimentin， an important inflammatory molecule， is closely related to the occurrence and development of HCC and its expression， subcellular location and function may be affected by cancer-associated fibroblasts， M2 macrophages， myeloid dendritic cell， and IL-6/STAT3 signaling pathway， particularly by STAT3 molecule. Jianpi Yiqi prescription may exert therapeutic effect on HCC via regulating Vimentin through the STAT3/Vimentin signaling pathway.

Objective:To explore the genetic causes of cerebellar hypoplasia (CH) diagnosed by prenatal ultrasound.Methods:This retrospective study involved 32 fetuses with CH diagnosed by prenatal ultrasound in Wuxi Maternal and Child Health Hospital from January 2014 to December 2022. Prenatal ultrasound findings and genetic testing results for amniotic fluid were collected and analyzed. The correlation between fetal CH and genetic abnormality was analyzed. A descriptive statistical method was used for data analysis.Results:(1) General data: The 32 mothers were (28.0±4.9) years old, ranging from 18 to 37 years old; the gestational age at amniocentesis was (24.2±4.0) weeks, ranging from 18 +3 weeks to 37 +2 weeks. Apart from one case lost to follow-up, the other 31 cases terminated the pregnancies, including 30 terminated before 28 weeks of gestation and one at 33 weeks of gestation due to unmarried status. (2) Ultrasonic features: Among the 32 cases, 30(93.8%) were complicated by intracranial or extracranial abnormalities including cardiac abnormalities (15 cases), dilated lateral ventricles (ten cases), and abnormalities in limbs (eight cases) and face (nine cases). Two CH cases (6.2%) were isolated. (3) Genetic testing: Among the 32 cases, 13 cases (40.6%) had normal results of amniotic fluid karyotype analysis and single nucleotide polymorphism (SNP) array. Among the 19 cases with abnormal amniotic fluid test results (59.4%), 16 cases have abnormal results in amniotic fluid karyotype analysis and SNP array detection [nine cases were numerical abnormalities, including five cases of trisomy-18, three of trisomy-21, and one of trisomy-13; seven cases were chromosomal structural abnormalities, including four cases of terminal deletion of chromosome 5 (Cri-du-Chat syndrome) and three cases of reciprocal translocation of chromosomes]. There was no abnormality in karyotype analysis of amniotic fluid in three cases. Still, their SNP array test results showed copy number variations (CNV) [one of 6q terminal deletion, one of 6q terminal deletion with 5p15.33 duplication, and one of 6q terminal deletion with 15q26.3 duplication; all variations were of unknown significance]. (4) Of the 19 cases with abnormal SNP array results, 17 were accompanied by abnormal intracranial/extracranial ultrasound findings. Among them, ten cases showed cardiac malformation, seven showed lateral ventricular widening, and seven showed limb abnormality. Conclusions:Numerical abnormalities, CDCS, and 6q terminal deletion are the most common genetic causes of CH diagnosed by prenatal ultrasound. Chromosome microarray analysis should be recommended for fetuses with ultrasound-diagnosed CH to evaluate fetal prognosis accurately.

The particle size was (467.3±42.3)nm, the structure was stable. The cisplatin targeted nanobubbles had a good effect of ultrasonic molecular development in SCLC xenograft.Compared with the control group, the proliferation of SCLC cells was significantly inhibited by cisplatin targeted nanobubbles. The RT-PCR and Western blotting analysis showed that compared with the control group, the mRNA and protein levels of the proliferation-related gene P53 and Rb in the cisplatin targeted nanovesicles group were significantly up-regulated, and the mRNA and protein levels of c-myc were significantly down-regulated (all P<0.05). Conclusions:The cisplatin targeted nanobubbles can inhibit the proliferation of SCLC, and may be used as a new potential targeted drug for the treatment of SCLC.

Defining and visualizing the three-dimensional (3D) structures of pharmaceuticals provides a new and important tool to elucidate the phenomenal behavior and underlying mechanisms of drug delivery systems. The mechanism of drug release from complex structured dosage forms, such as bilayer osmotic pump tablets, has not been investigated widely for most solid 3D structures. In this study, bilayer osmotic pump tablets undergoing dissolution, as well as after dissolution in a desiccated solid state were examined, and visualized by synchrotron radiation micro-computed tomography (SR-μCT). In situ formed 3D structures at different in vitro drug release states were characterized comprehensively. A distinct movement pattern of NaCl crystals from the push layer to the drug layer was observed, beneath the semi-permeable coating in the desiccated tablet samples. The 3D structures at different dissolution time revealed that the pushing upsurge in the bilayer osmotic pump tablet was directed via peripheral "roadways". Typically, different regions of the osmotic front, infiltration region, and dormant region were classified in the push layer during the dissolution of drug from tablet samples. According to the observed 3D microstructures, a "subterranean river model" for the drug release mechanism has been defined to explain the drug release mechanism.

OBJECTIVE：To explore the therap eutic effects and its mech anism of Jianpi yiqi decoction on diethylnitrosamine （DEN）induced liver cancer model rats. METHODS ：Totally 80 male SD rats were divided into normal group ，model group ， Nod-like receptor family 3（NLRP3）inhibition group （MCC950，4.5 mg/kg），caspase-1 inhibitory group （VX-765，4.5 mg/kg）， Jianpi yiqi decoction low-dose ，medium-dose and high-dose groups （5.25，10.5，21 g/kg），with 10 rats in each group except for 20 rats in model group （10 of them were only used to judge whether modeling was successful ）. Rats in each group were intraperitoneally injected with DEN （70 mg/kg）to induce liver cancer model ，except for the rats in normal group which were replaced by normal saline. After modeling ，normal group and model group were given normal saline intragastrically ；inhibitor groups were given relevant medicine intraperitoneally ；Jianpi yiqi decoction groups were given relevant medicine intragastrically ， once a day ，for consecutive 4 weeks.

Liver 198086， tissue injury index ，serum content of TNF-α and IL-1β as well as the protein expression of NLRP 3，ASC，pro-caspase-1，RIP1，RIP3 and MLKL in liver tissue were significantly increased （P＜0.05 or P＜0.01）. Compared with model 防治。E-mail：sherwin_zhuo@126.com group，there were still a large number of inflammatory cell infiltration in the liver tissue of rats in Jianpi yiqi decoction low-dose and medium dose groups ，while the inflammatory cell infiltration of rats in high-dose group and inhibitor groups decreased significantly ；the liver tissue injury index and above indexes levels in serum and liver tissue were decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：Jianpi yiqi decoction shows therapeutic effect on liver cancer model rats ，the mechanism of which may be associated with down-regulating the expression of NLRP3 inflammasome and inhibiting programmed cell necrosis.

FTY720 and IMMH002, prodrugs for sphingosine-1-phosphate receptor 1 (S1P) agonists, show inadequate and inconsistent levels of phosphorylation in humans compared to that in rats. In this study, FTY720 or IMMH002 analogues (-) were designed and synthesized with modified head pieces to improve the biotransformation of the prodrugs to the active phosphorylated forms. Target compounds were synthesized a convergent route using the key and optically pure building block , which was first synthesized asymmetrically catalyzed amination. The phosphorylation rates of these analogues in rat or human blood were compared. The new methyl-substituted analogue compound showed higher phosphorylation rates in both rats and humans than the parent compound, whereas compound showed improvements in rats, but not in humans. In pharmacokinetics studies of rats, compounds and both had higher levels of phosphorylation than FTY720 and IMMH002. Thus, our study not only yielded new compounds with therapeutic potential, but also showed species differences between rats and humans in response to the structural modifications, which might be useful for predicting the biotransformation behavior and efficacy of this class of prodrugs in the clinic.

Psoriasis is characterized by abnormal proliferation of keratinocytes, as well as infiltration of immune cells into the dermis and epidermis, causing itchy, scaly and erythematous plaques of skin. The understanding of this chronic inflammatory skin disease remains unclear and all available treatments have their limitations currently. Here, we showed that IMMH002, a novel orally active S1P modulator, desensitized peripheral pathogenic lymphocytes to egress signal from secondary lymphoid organs and thymus. Using different psoriasis animal models, we demonstrated that IMMH002 could significantly relieve skin damage as revealed by PASI score and pathological injure evaluation. Mechanistically, IMMH002 regulated CD3 T lymphocytes re-distribution by inducing lymphocytes' homing, thus decreased T lymphocytes allocation in the peripheral blood and skin but increased in the thymus. Our results suggest that the novel S1P agonist, IMMH002, exert extraordinary capacity to rapidly modulate T lymphocytes distribution, representing a promising drug candidate for psoriasis treatment.

Chimeric antigen receptor T-cell strategy targeting CD19 (CART19) has prominent anti-tumor effect for relapsed/refractory B-cell lymphomas. CART19-associated complications have been gradually recognized, however, late-onset complications have not been extensively studied. Herein, for the first time we report a diffuse large B-cell lymphoma patient with terminal ileum involvement obtained rapid remission and developed spontaneous terminal ileal perforation 38 days following CART19 infusion. The late-onset perforation reminds us that, for the safety of CART treatment, more cautions are warranted for the management of delayed GI complications.
