Attention is the cornerstone of effective functioning in a complex and information-rich world. While the neural activity of attention has been extensively studied in the cortex, the brain-wide neural activity patterns are largely unknown. In this study, we conducted a comprehensive analysis of neural activity across the mouse brain during attentional processing using EEG and c-Fos staining, utilizing hierarchical clustering and c-Fos-based functional network analysis to evaluate the c-Fos activation patterns. Our findings reveal that a wide range of brain regions are activated, notably in the high-order cortex, thalamus, and brain stem regions involved in advanced cognition and arousal regulation, with the central lateral nucleus of the thalamus as a strong hub, suggesting the crucial role of the thalamus in attention control. These results provide valuable insights into the neural network mechanisms underlying attention, offering a foundation for formulating functional hypotheses and conducting circuit-level testing.

Objective To explore the role and mechanism of mechanically sensitive ion channel Piezo2 in mechanical allodynia of rats with low back pain induced by simulating the low-frequency vibration of a helicopter.Methods Low-frequency vibration(LFV)model with 3-dimensional 6 degrees of freedom was used to induce low back pain in awake rats in a sitting position.Twenty-four male SD rats(8 weeks old)were randomly divided into control(Ctrl)group and LFV group.HE staining was used to evaluate the injury of the multifidus muscle.Von Frey test was carried out to detect pain sensitivity.Open field test was employed to assess the spontaneous activity and anxiety.ELISA,Western blotting and immunofluorescence staining were performed to detect the expression of NGF,TrkA and downstream molecule Piezo2.Dorsal root ganglia(DRG)neurons was isolated from SD rats and primarily cultured.After identified with immunofluorescence staining,the neurons were divided into the Ctrl group,the LFV group,and the LFV+D-GsMTx4(D-G4,an Piezo2 channel antagonist)group.Western blotting was used to detect the protein expression of Piezo2,and a calcium ion fluorescent probe was utilized to detect the intracellular Ca2+.The DRG neurons were pretreated with 50 ng/mL NGF for 1 h.Calcium ion fluorescent probe was used to observe the changes in intracellular Ca2+in the LFV group,the LFV+NGF group,and the LFV+NGF+D-G4 group.Results The rats of the LFV group showed abnormal morphology in multifidus muscles,accompanied with inflammatory cell infiltration,decreased paw withdrawal reflex threshold(P<0.05),and shortened total active time and active time in the centre,and decreased distance traveled in the centre(P<0.05),while prolonged total stationary time,stationary time in the periphery,and increased distance traveled in the periphery(P<0.05),and moreover,enhanced expression of Piezo2,NGF and TrkA in the DRG tissues(P<0.05).Cell experiments showed that compared with the Ctrl group,the expression of Piezo2 in the neurons was increased(P<0.05),and the intracellular Ca2+level was significantly elevated in the LFV group(P<0.05).Compared with the LFV group,the Ca2+level was higher in the LFV+NGF group(P<0.05),and the sensitization effect of NGF on Piezo2 was reversed after D-G4 treatment(P<0.05).Conclusion Sustained low-frequency vibration induces low back pain and mechanical allodynia in rats through the NGF-TrkA/Piezo2 pathway.

The tumor microenvironment (TME) is the cellular milieu in which tumor cells thrive, comprising interacting cells and associated factors that form a complex network of interactions, directly or indirectly influencing the initiation, progression, and metastasis of lung cancer. Through TCM pattern identification, it has been observed thatphlegm-pathogen is closely associated with disorder in the inflammatory-metabolic-immune microenvironments of lung cancer. This involves three key pathological mechanisms: "phlegm-stasis complicated by toxin, qi deficiency with exuberant phlegm, and phlegm-pathogen impairing healthy qi". Molecular mechanism studies have revealed that phlegm-resolving agents can extensively modulate multiple targets or pathways, thereby remodeling the inflammatory-metabolic-immune microenvironments of lung cancer. Consequently, a comprehensive therapeutic strategy integrating "resolving phlegm, dispelling stasis, and detoxifying; supplementing qi, warming yang, and resolving phlegm; and reinforcing healthy qi, tonifying the lung, and eliminating phlegm" is essential to reshape the lung cancer TME and enhance antitumor efficacy.

Objective To investigate the impact of transtheoretical model-based depression management on senile people with type 2 diabetes. Methods A total of 78 senile patients with type 2 diabetes were recruited from the Affiliated Jiangyin Hospital of Southeast University Medical College and the Nantong Tumor Hospital during the period from September 2015 to December 2016.They were randomly divided into the experimental(n=39)and the control groups(n=39).The patients in the experimental group received transtheoretical model-based depression management while those in the control group received traditional health education. The intervention results were evaluated using Demographic Data Recording Form, Self-Rating Depression Scale, and Depression Prevention & Management Survey Items. The main statistical methods included Chi square test,independent sample t test,Mann-Whitney U test,and repeated measures analysis of variance. Results After the intervention of three months, the mean scores of Self-Rating Depression Scale was 50.97 (F=17.814), perceived benefit score was (9.59 ± 2.10) (t=-6.732), perceived barriers score was (5.59 ± 1.30) (t=2.980), cognitive level score was (32.98 ± 4.87) (t=-10.189), the behavior level score was (34.32 ± 5.02) (t=-13.745), and the self-efficacy score was (12.11 ± 2.13)(t=-7.845),all of which significantly improved in the experimental group,more than the control group with its perceived benefit score of(8.31 ± 1.12)(F=32.789),perceived barriers score of(6.99 ± 2.12)(F=18.788), cognitive level score of (29.01 ± 3.34) (F=67.876), behavior level score of (28.03 ± 4.77) (F=43.476), and self-efficacy score of(9.78 ± 2.03)(F=15.543),and the difference was statistically significant(P<0.01).The level of FPG in experimental group was(7.24 ± 1.36)mmol/L,which was significantly lower than the FPG of (7.41 ± 1.34)mmol/L in the control group(t=0.624,P=0.028).Conclusions Transtheoretical model-based depression management can effectively improve senile type 2 diabetes'management of depression,which is valuable in the clinical context.

BACKGROUND: Idiopathic scoliosis is a common spinal deformity in teenagers, which is managed mainly by orthomorphia. However, due to great trauma, long operative duration and large blood loss, a great amount of blood transfusion is needed during the surgery. Allogeneic blood transfusion should be reduced in order to release blood insufficient, decline blood transfusion expense, as well as avoid transfusion diseases. OBJECTIVE: To investigate the value of controlled hypotension combined with autotransfusion in idiopathic scoliosis orthomorphia.METHODS: Intraoperative controlled hypotension was performed during posterior orthomorphia surgery on all the 46 cases of idiopathic scoliosis, 17 cases in which were served as the control group, who underwent allogeneic blood transfusion without autotransfusion, while the other 29 cases were served as the experimental group, who underwent autotransfusion that including reinfusion of preoperative deposited autologous blood and intra-operative salvaged autologous blood. The blood loss volume and transfusion status in two groups were observed. RESULTS AND CONCLUSION: Blood loss volume in the control group was 400-1 000 (867±161) mL, and that in the experimental group was 350-1400 (842±376) mL, There was no marked difference between the two groups (P > 0.05). The volume of allogeneic blood transfusion in the control group was 500-1 800 (845±332) mL, which was greater than that in the experimental group [0-1 300(423±237) mL] (P < 0.01). The results suggested that controlled hypotension reduces intraoperative bleeding, and postoperative autotransfusion minimizes the need of allogeneic blood transfusion.

Objective To develop a new scoring system,Daping orthopedics operation risk scoring system for senile patient(DORSSSP),for preoperative evaluation of operative risks in the elderly patients with hip fractures based on acute physiology and chronic health evaluation(APACHE)Ⅱ scoring system and physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM)and compare the new scoring system with APACHE Ⅱ and POSSUM in assessing surgical risks and predicting postoperative complications and mortalities.Methods A total of 260 patients with hip fractures treated in our department in recent five years were retrospectively and respectively evaluated with DORSSSP,POSSUM,progressed POSSUM(P-POSSUM)and APACHE Ⅱ scoring system to compare the value of three scoring systems in preoperative evaluation of operative risks and prediction of postoperative mortality and complications.Results POSSUM and DORSSSP predicted complications in 119 and 92 patients respectively,while the actual complication occurred in 84 patients.The prediction value of POSSUM was significantly higher than the actual value,while the prediction value of DORSSSP showed no statistical difference compared with the actual value.POSSUM,P-POSSUM and APACHEⅡ scoring systems predicted 16,10 and 12 deaths respectively,but there were six deaths in fact,with prediction value obviously higher than the actual value.DORSSSP predicted nine deaths,the closest value to the actual.Conclusions DORSSSP has good correlation with postoperative complications and mortalities.Compared with POSSUM and APACHE Ⅱ scoring system,more simple and practicable DORSSSP can more accurately evaluate the preoperative risks and predict the postoperative complications and mortalities in the elderly patients with hip fractures.
