Objective:To investigate the clinical effectiveness of Du Meridian moxibustion combined with brisk walking on negative symptoms, cognitive function, and social function in patients with stable schizophrenia, aiming to provide a feasible adjunctive treatment for clinical practice.Methods:A randomized controlled trial was conducted using convenience sampling to recruit 140 patients with stable schizophrenia hospitalized at the Affiliated Brain Hospital of Guangzhou Medical University from April 1, 2023, to March 31, 2024. Patients were randomly assigned to a control group, Du Meridian moxibustion group, brisk walking group, or combined group, with 35 patients in each group. The control group received standard care. On this basis, the Du Meridian moxibustion group received moxibustion on the Du Meridian, the brisk walking group participated in slow walking exercises, and the combined group received both interventions for 12 weeks. Assessments were conducted at baseline, at 6 and 12 weeks during the intervention, and at 12 weeks post-intervention using the Scale for the Assessment of Negative Symptoms, Mini-Mental State Examination, and Social Functioning Scale for Inpatient Psychiatric Patients.Results:A total of 134 patients completed the study: control group ( n = 34), Du Meridian moxibustion group ( n = 34), brisk walking group ( n = 35), and combined group ( n = 31). The combined group demonstrated significantly lower SANS scores at the 12th week of intervention (49.71 ± 4.66) and at 12 weeks post-intervention (53.45 ± 5.34) compared to the Du Meridian moxibustion group (54.91 ± 4.79) and (59.56 ± 5.84), the brisk walking group (56.69 ± 5.59) and (58.51 ± 5.42), control group (65.71 ± 4.95) and (66.21 ± 4.33), with statistically significant differences ( t values were 3.81-13.37, all P<0.05). Regarding cognitive function, the MMSE scores in the combined group at the 12th week of intervention (28.23 ± 1.28) and at 12 weeks post-intervention (27.35 ± 1.76) were higher than those in the Du Meridian moxibustion group (26.79 ± 1.85) and (25.59 ± 2.27) and the brisk walking group (25.88 ± 2.23) and (25.43 ± 1.84), control group (23.65 ± 2.17) and (22.32 ± 2.14), with statistically significant differences ( t values were - 10.28 to - 3.48, all P<0.001). For social function, the SSPI scores in the combined group at the 12th week of intervention (35.71 ± 3.63) and at 12 weeks post-intervention (32.58 ± 3.71) were also significantly higher than those in the Du Meridian moxibustion group (32.21 ± 3.91) and (28.47 ± 3.70) and the brisk walking group (31.83 ± 3.54) and (30.31 ± 3.59), control group (24.53 ± 4.12) and (24.15 ± 3.50) with statistically significant differences ( t values were - 11.56 to - 2.52, all P<0.05). Conclusions:The combination of Du Meridian moxibustion and brisk walking is an effective adjunctive intervention for patients with stable schizophrenia, as it significantly reduces negative symptoms, enhances cognitive function, and improves social functioning.

Objectives:To investigate the current willingness of depressive outpatients and their doctors in China to engage in shared decision-making (SDM), and to analyze the factors influencing this willingness.Methods:A questionnaire survey was conducted among doctors and patients with depression in 12 tertiary psychiatric hospitals and general hospitals by scanning two-dimensional code and filling in the questionnaire on the mobile terminal. The questionnaire covered patient demographics, emotional state scores, initial diagnosis and treatment, treatment expectations and concerns, symptom improvement needs, medication safety requirements, and diagnosis details (completed by the attending physician). Doctors provided basic information, current depression diagnosis and treatment status, and concerns regarding medications. Logistic regression analysis (univariate and multivariate) was used to identify factors influencing patients′ and doctors′ willingness to engage in SDM.Results:A total of 622 valid patient questionnaires and 45 valid physician questionnaires were collected. Both patients and doctors had a strong willingness to make shared decisions (80.39% (500/622) vs. 60.00% (27/45)). Multivariate binary logistic regression analysis showed that residential location (town versus rural areas: OR (95% CI)=1.895 (1.087-3.305)), acceptable monthly medical expenses (≥1 000-<2 000 CNY vs.<300 CNY: OR (95% CI)=0.194 (0.088-0.427);≥2 000 CNY vs.<300 CNY: OR (95% CI)=0.267 (0.094-0.754)), acceptance of online treatment and consultation (accept versus not accept: OR (95% CI)=3.196 (2.024-5.046)), and knowing about psychotherapy (yes versus no: OR (95% CI)=1.711 (1.003-2.921)) were the factors influencing the willingness of shared decision-making in patients (all P<0.05). For the doctors, the time spent on initial consultation was the factor influencing the willingness to engage in SDM ( OR (95% CI)=1.090 (1.004-1.184), P=0.040). Conclusions:Both depression patients and doctors in tertiary outpatient clinics in China show a strong willingness to engage in SDM, providing a solid foundation for clinical application. However, it is necessary to pay attention to the influence of residential location, acceptable monthly medical expenses, acceptance of online treatment and consultation, and knowledge of psychotherapy should be considered for patients, while the time spent on initial consultations should be considered for doctors.

Objective To study the differences in the blood cell analysis of male officers and soldiers be-tween in the high altitude area station and low altitude area station in summer.Methods A total of 239 male officers and soldiers in the high altitude area(Amdo Xizang,average altitude 4 800 m)and 336 male officers and soldiers in the low altitude area(Nanjing,Jiangsu,average altitude 30 m)from July 18 to 24,2022 were selected as the study subjects and the differences in blood cell analysis parameters of male officers and soldiers stationed between at high altitude and low altitude areas were retrospectively analyzed.Results The eosino-phils percentage(EDS％),eosinophils count(EOS)in the high altitude group were significantly lower than thosein the low altitude group(P＜0.05),and the basophillic granulocyte percentage(BASO％),basophillic granulo-cyte count(BASO)and monocyte percentage(MONO％)were significantly higher than those in the low alti-tude group,and the differences were statistically significant(P＜0.05),but which in the both groups were in the normal reference ranges.The red blood cell count(RBC)hemoglobin(Hb)and hematocrit(HCT)in the high altitude group were significantly higher than those in the low altitude group(P＜0.05),moreover Hb and HCT in the high altitude group were in the upper limit of the medical reference range.The mean corpus-cular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and red blood cell distribution width-standard diviation(RDW-SD)in the high altitude group were lower than those in the low-altitude group(P＜0.05),but the both groups were in the normal reference ran-ges;there was no statistically significant difference in the erythrocyte distribution width coefficient of variation(RDW-CV)between the two groups(P＞0.05).The platelet(PLT)and thrombocytocrit(PCT)in the high altitude group were higher than those in the low altitude group,the platelet distribution width(PDW),mean platelet volume(MPV)and platelet large cell ratio(P-LCR)were lower than those in the low altitude group,and the differences were statistically significant(P＜0.05);PDW in the low-altitude group was at the upper limit of the medical reference range,and the other platelet-related indexes were in the normal range.Conclusion There are obvious differences in the blood cell analysis indicators of male officers and soldiers be-tween the high altitude area and low altitude area.

BACKGROUND:Tyrosine kinase inhibitors,as well as other types of small-molecule cancer drugs,can cause severe cardiotoxicity. OBJECTIVE:To perform a heart safety re-evaluation by observing the effects of antitumor drugs on isolated heart electrocardiograph,cardiac action potential and associated ion channels and cytotoxicity. METHODS:Extracorporeal cardiac perfusion was given to the isolated rabbit heart using Langendorff perfusion:Sunitinib(0.3,3,10 μmol/L),Crizotinib(0.3,1,3 μmol/L),and Doxorubicin(1,30 μmol/L)were perfused sequentially for 120 minutes to record electrocardiograph and left ventricular pressure.A blank control group was set for comparison.Manual patch clamp was used to record the effects of Crizotinib,Sunitinib,Doxorubicin on hERG,Cav1.2,Nav1.5 channel currents and action potential in human induced pluripotent stem cell derived cardiomyocytes.Adenosine triphosphate level in human induced pluripotent stem cell derived cardiomyocytes was detected by CellTiter-Glo luminescent cell viability assay. RESULTS AND CONCLUSION:Isolated rabbit heart using Langendorff perfusion:Compared with the blank ontrol group,Sunitinib and Crizotinib at≥3 μmol/L decreased heart rate(P<0.01)and prolonged QT/QTc interval(P<0.01),and reduced left ventricular pressure to different extents.Manual patch clamp recording:Compared with the blank control group,Sunitinib and Crizotinib at 3 μmol/L inhibited the activities of hERG,Nav1.5 and Cav1.2 channels and significantly prolonged the duration of action potential(P<0.01).According to the analysis of the test article,the difference between the labeled concentration and the measured concentration of the recovered solution was not significant.Cell viability assays:Compared with the blank control group,adenosine triphosphate content in human induced pluripotent stem cell derived cardiomyocytes significantly decreased after treatment with Sunitinib(IC50=4.64 μmol/L),Doxorubicin(IC50=4.21 μmol/L)and Crizotinib(IC50=2.87 μmol/L),indicating that cell viability significantly decreased(P<0.01).To conclude,this study successfully established an early cardiac safety evaluation method for antitumor drugs,which provides good support and help for the subsequent development of antitumor drugs.

A colon-specific drug delivery system has great potential for the oral administration of colorectal cancer. However, the uncontrollable in vivo fate of liposomes makes their effectiveness for colonic location, and intratumoral accumulation remains unsatisfactory. Here, an oral colon-specific drug delivery system (CBS-CS@Lipo/Oxp/MTZ) was constructed by covalently conjugating Clostridium butyricum spores (CBS) with drugs loaded chitosan (CS)-coated liposomes, where the model chemotherapy drug oxaliplatin (Oxp) and anti-anaerobic bacteria agent metronidazole (MTZ) were loaded. Following oral administration, CBS germinated into Clostridium butyricum (CB) and colonized in the colon. Combined with colonic specifically β-glucosidase responsive degrading of CS, dual colon-specific release of liposomes was achieved. And the accumulation of liposomes at the CRC site furtherly increased by 2.68-fold. Simultaneously, the released liposomes penetrated deep tumor tissue via the permeation enhancement effect of CS to kill localized intratumoral bacteria. Collaborating with blocking the translocation of intestinal pathogenic bacteria from lumen to tumor with the gut microbiota modulation of CB, the intratumoral pathogenic bacteria were eliminated fundamentally, blocking their recruitment to immunosuppressive cells. Furtherly, synchronized with lipopolysaccharide (LPS) released from MTZ-induced dead Fusobacterium nucleatum and the tumor-associated antigens produced by Oxp-caused immunogenic dead cells, they jointly enhanced tumor infiltration of CD8⁺ T cells and reactivated robust antitumor immunity.
