ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work， thereby providing a theoretical basis for the improvement of education and training， incentive mechanisms， and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method， semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest， empathy， and a sense of professional responsibility， while the negative was low psychological resilience. External positive driving forces included high work support， professional identity， mutual benefits for nurses and patients， and positive patient attitudes， whereas negative driving forces comprised busy routine clinical work， lack of a reward and incentive system， and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care， intensify the publicity of palliative care and death education； intervene and guide nurses’ negative emotions， improve and implement relevant incentive systems， and standardize the job recognition and scope of responsibilities of palliative care nurses.

Objective:To investigate the clinical efficacy of transcranial alternating current stimulation (tACS) combined with drug treatment in patients with bipolar Ⅰ disorder (BD Ⅰ).Methods:Forty-two patients with BD Ⅰ who were admitted to the Mental Health Center Affiliated to Anhui Medical University from March 2022 to June 2023 were included in this randomized double-blind study. These patients were randomly divided into a control group and an observation group using an Excel spreadsheet. In the control group, patients received 10 sessions of sham stimulation in addition to drug treatment, while the observation group received 10 sessions of tACS along with drug treatment. All patients were treated for 2 weeks. Each patient received stimulation for 15 minutes on each of the right and left prefrontal lobes once every working day. The Montreal Cognitive Assessment (MoCA) scores and Bech-Rafaelsen Mania Scale (BRMS) scores were compared between the two groups before and after treatment. Eighteen patients from the observation group and nineteen patients from the control group were included in the final analysis.Results:Two weeks after treatment, the MoCA score in the observation group was higher than that in the control group [(27.39 ± 1.88) vs. (24.63 ± 2.39)], and the BRMS score in the observation group was lower than that in the control group [(15.89 ± 3.18) vs. (19.00 ± 3.32)]. These differences were statistically significant ( t = -3.89, 2.91, both P < 0.05). After treatment, the MoCA score in the observation group increased, while the BRMS score decreased ( t = 5.04, -4.14, both P < 0.05). Pearson correlation analysis indicated the change in MoCA score was negatively correlated with BRMS score in both groups ( r = -0.433, P < 0.05). Conclusions:Drug treatment combined with tACS greatly improved clinical cognitive symptoms and reduced manic symptoms in patients with BD Ⅰ. The combined therapy exhibited better efficacy than monotherapy.

Objective:To explore the impact of previous cytomegalovirus (CMV), herpes simplex virus (HSV), and rubella virus (RV) infection on pregnancy outcomes in infertile women undergoing the first in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) treatment. Methods:A retrospective cohort study was conducted to analyze the clinical data of women who underwent IVF/ICSI-ET for the first time at the Reproductive Medicine Center, the First Affiliated Hospital of Zhengzhou University from December 2017 to December 2022. The patients were divided into CMV-IgG (+) group ( n=154), RV-IgG (+) group ( n=86), HSV-IgG (+) group ( n=93) and IgG all-negative group ( n=172). The pregnancy outcomes of the patients in the virus-only infection group and the IgG all-negative group were compared. Patients who were previously co-infected with CMV and HSV were classified as the CMV+HSV-IgG (+) group ( n=344), and the pregnancy outcomes of patients with previous CMV and HSV co-infection and those with infection alone were further compared. Results:The two pronuclei (2PN) fertilization rate [63.90% (1 195/1 870)], the clinical pregnancy rate [51.30% (79/154)], and the live birth rate [45.45% (70/154)] of the CMV-IgG (+) group were significantly lower than those of the IgG completely negative group [68.68% (1 469/2 139), P=0.001; 68.60% (118/172), P=0.001; 61.05% (105/172), P=0.005]. The 2PN fertilization rate [61.62% (729/1 183)], the clinical pregnancy rate [50.54% (47/93)], and the live birth rate [43.01% (40/93)] of the HSV-IgG (+) group were significantly lower than those of the IgG completely negative group [68.68% (1 469/2 139), P=0.001; 68.60% (118/172), P=0.004; 61.05% (105/172), P=0.005]. There were no statistical differences in the 2PN fertilization rate, the clinical pregnancy rate, and the live birth rate between the RV-IgG (+) group and the IgG completely negative group (all P>0.05). Compared with the IgG completely negative group, there were no significant differences in the risk of complications such as gestational diabetes, hypertensive disorders of pregnancy and neonatal outcomes in the CMV-IgG (+) group, RV-IgG (+) group, and HSV-IgG (+) group (all P>0.05). Multivariate logistic regression analysis showed that CMV-IgG (+) ( OR=0.453, 95% CI: 0.280-0.734, P=0.001; OR=0.515, 95% CI: 0.321-0.825, P=0.006), HSV-IgG (+) ( OR=0.425, 95% CI: 0.245-0.738, P=0.002; OR=0.447, 95% CI: 0.259-0.771, P=0.004) and CMV+HSV-IgG (+) ( OR=0.491, 95% CI: 0.329-0.733, P=0.001; OR=0.528, 95% CI: 0.357-0.780, P=0.001) were all independent influencing factors of patients' clinical pregnancy and live birth. There were no statistical differences in the clinical outcomes between the previous CMV and HSV co-infection group and the single infection group ( P>0.05). Conclusion:Previous CMV or HSV infection alone reduced the fertilization rate, the clinical pregnancy rate and the live birth rate of patients undergoing IVF/ICSI-ET treatment, but had no significant impact on pregnancy complications and neonatal outcomes. Pregnancy outcomes of patients with previous CMV and HSV co-infection were similar to those with infection alone.

Objective:To investigate the possible mechanism of Zaogong Erteng decoction (ZGETD) in the treatment of endometritis.Methods:Femal mice were injected 2.5 mg/mL lipopolysaccharide into uterine horn to induce endometritis model. After modelling, low-dose ZGETD, high-dose ZGETD or amoxicillin was given once a day for 7 d. The appearance of the uterus and pathological changes of uterine tissue were observed 7 d later, and the uterine index was calculated. The expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 in mouse uterine tissue was detected by enzyme-linked immunosorbent assay. The activity of myeloperoxidase (MPO) in mouse uterine tissue was measured by redox reaction. The active ingredients of ZGETD and the target and signal pathway of treatment of endometritis were analyzed by network pharmacology. Western blotting and qRT-PCR were used to detect the expressions of Toll-like receptor 4 (TLR4), P65, p-P65, interferon regulatory factor 3 (IRF3) and p-IRF3 proteins and chemokines CXCL5 and CXCL8 in the mouse uterus, respectively. Terminal dUTP nick end labeling detected endometrial cell apoptosis and endometrial thickness was measured. After treatment, the female rats were mated with the male rats, and the mating rate, the pregnancy rate and the number of implantation sits in the injected uterine horn on day 8 of gestation were counted. Results:Both ZGETD and amoxicillin have atherapeutic effect on endometritis, but compared with low-dose ZGETD and amoxicillin, high-dose ZGETD can significantly alleviate the edema and congestion of uterine tissue and reduce the uterine index (all P=0.001). After treatment, the uterine cavity epithelium of mice was smooth and complete, the uterine gland structure was normal, and no bleeding area and inflammatory cell aggregation were observed. Compared with amoxicillin, high-dose ZGETD significantly decreased the expression of inflammatory factors (TNF-α, IL-1β and IL-6) and MPO activity (all P<0.001). The expression of chemokines ( CXCL5 and CXCL8) was significantly reduced (all P<0.05). The signaling pathways TLR4, nuclear factor kappa-B (NF-κB) and TNF related to the treatment of endometritis by ZGETD were screened by network pharmacology, and their action targets (TLR4, NF-κB and IRF3) were verified. Quercetin, fisetin and luteolin were found to be the most active ingredients acting on these targets. High-dose ZGETD significantly inhibited the activation of TLR4/NF-κB and TLR4/IRF3 pathways ( P<0.05), decreased endometrial cell apoptosis ( P<0.05), and increased endometrial thickness ( P<0.001), mating rate ( P<0.001), pregnancy rate ( P<0.001) and implantation site number of uterine horn on the injection side of LPS after treatment ( P=0.001). Conclusion:High-dose ZGETD has a significant therapeutic effect on endometritis, which may be closely related to the down-regulation of TLR4 signaling pathway.

Objective:To explore the factors that tend to lead to a low normal fertilization rate in spindle transfer of mouse oocytes and its strategies.Methods:Oocytes in metaphase Ⅱ (MⅡ) of C57BL/6 and ICR strains mouse were obtained for observations of mitochondrial replacement operations. Spindle karyoplasts of three different sizes (large, medium, small) were isolated by micromanipulation, and their morphology was observed under bright field and polarized light at 0 min, 10 min, 20 min and 30 min after suction. For small spindle karyoplasts, 2% paraformaldehyde fixation was performed after 10 min, 20 min and 30 min respectively, and the morphology of spindle and chromosomes was observed after immunofluorescence staining. Intracytoplasmic sperm injection (ICSI) was performed on oocytes, followed by small spindle karyoplasts isolation, and then fusion was conducted after 30 min (traditional method), 10 min (modified method 1) and 0 min (modified method 2) respectively. ICSI-oocytes without spindle transfer were used as control group, and 14-16 h later, the fertilization of reconstructed oocytes was observed and statistically analyzed.Results:1) When spindle karyoplast was just retrieved (0 min), the karyoplast membrane was smooth and complete, and the spindle showed a normal spindle shape. After 10 min, 20 min and 30 min of suction, the karyoplast membrane was twisted or elongated with an irregular morphology, and the spindle was also twisted, stretched or scattered with a weaker brightness. And the smaller spindle karyoplast, the more serious the deformation was. 2) When the spindle was just taken out (0 min), immunofluorescence staining showed that the spindle was in a standard spindle shape, and the chromosomes were regularly and neatly arranged on the equatorial plate. With the prolongation of placement time, spindles were elongated and tapered or dumbbell-shaped, and chromosomes were scattered and irregularly arranged. 3) For the traditional method of spindle transfer, the normal fertilization rate of C57BL/6 mouse reconstructed oocytes was 63.16% (24/38), which was statistically different from that of control group ( P=0.002). The normal fertilization rate [68.00% (34/50)] in the modified method 1 group was significantly lower than that in control group [90.00% (36/40), P=0.019], but there was no statistical difference with the traditional method ( P=0.260). However, the normal fertilization rate [82.50% (33/40)] in the modified method 2 group was similar to control group ( P=0.422), and was significantly higher than that of the traditional method group ( P=0.010). Conclusion:The longer the spindle karyoplast of mouse oocytes is stayed after retrieval, the more serious the morphological changes, the more unstable the spindles and chromosomes, and the lower normal fertilization rate. Immediate fusion of spindle karyoplast after isolation is the best time for mitochondrial replacement micromanipulation.

Objective:To analyze the exercise rehabilitation preference of stroke patients, and provide reference for clinical medical staff to formulate personalized exercise rehabilitation scheme, construct precise rehabilitation decision support system, and develop exercise rehabilitation intelligent service platform.Methods:A convenience sampling approach was employed to select the stroke patients in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from June to December 2024, a face to face cross-sectional survey was conducted using the questionnaire on exercise rehabilitation preferences of stroke patients based on the method of discrete choice experiments. The obtained data were analyzed using conditional Logit model.Results:Finally, 242 stroke patients were included, including 152 males and 90 females, aged 64 (56, 69) years. The six attributes included in this study: rehabilitation goal, rehabilitation setting, exercise intensity, exercise duration, exercise supervision method, and payment method. The relative importance of each attribute was ranked as follows: payment method (37.1%), exercise duration (15.5%), supervision method (14.3%), rehabilitation setting (14.1%), exercise intensity (11.4%), and rehabilitation goal (7.6%). The most preferred combination was identified as a rehabilitation goal of ≥70% recovery, professional institution/hospital as the setting, supervision by wearable device combined with professional guidance, low-intensity exercise, a duration of 30-60 minutes per session, and a self-payment rate of <30%. Under this combination, the probability of patients choosing the rehabilitation program was 75.4%.Conclusions:Stroke patients' preferences for exercise rehabilitation are influenced by multiple factors, with substantial heterogeneity observed across individuals. Rehabilitation programs should be tailored according to patients' preferences regarding goals, settings, duration, and other key attributes to enhance adherence and optimize rehabilitation outcomes.

Hepatocellular carcinoma(HCC),as the most common type of liver cancer,poses a significant threat to global public health due to its high incidence and mortality rates.This paper delves into the etiology,pathogenesis,and syndrome differentiation of liver cancer from the perspective of"dispersing qi and fortifying the body resistance",based on the clinical experience of renowned traditional Chinese medicine(TCM)practitioner,Prof.Changquan Ling.Prof.Ling believes that the development of liver cancer is closely related to the disruption of liver qi flow,the accumulation of blood stasis over time,and the generation of toxin from long-term stagnation,accompanied by pathological changes such as imbalance of yin and yang,deficiency of the body's vital qi and accumulation of pathogenic factors,and internal blazing of cancer toxins.In terms of treatment,he emphasizes the principles of dispersing qi and fortifying the body resistance,addressing both the root cause and symptoms.This is achieved by regulating the functions of viscera,improving the stagnation of qi flow,and supplemented by methods such as clearing heat and detoxifying,and softening and dispersing hard masses,aiming to break the vicious cycle of qi stagnation,deficiency of vital qi,and pathogenic factor generation,thereby promoting the recovery from the disease.Through detailed analysis of clinical cases,this paper demonstrates Prof.Ling's unique insights and significant efficacy in treating liver cancer through"dispersing qi"to"fortify the body resistance",ultimately achieving"tumor suppression".This provides new references and perspectives for the clinical diagnosis and treatment of liver cancer in TCM.
