In modern society, people are increasingly exposed to chronic stress, leading to various mental disorders. However, the activities of brain regions, especially neural firing patterns related to specific behaviors, remain unclear. In this study, we introduce a novel approach, NeuroSync, which integrates open-field behavioral testing with electrophysiological recordings from emotion-related brain regions, specifically the central amygdala and the paraventricular nucleus of the hypothalamus, to explore the mechanisms of negative emotions induced by chronic stress in mice. By applying machine vision techniques, we quantified behaviors in the open field, and signal processing algorithms elucidated the neural underpinnings of the observed behaviors. Synchronizing behavioral and electrophysiological data revealed significant correlations between neural firing patterns and stress-related behaviors, providing insights into real-time brain activity underlying behavioral responses. This research combines deep learning and machine learning to synchronize high-resolution video and electrophysiological data, offering new insights into neural-behavioral dynamics under chronic stress conditions.

Tinnitus is a clinically refractory disease with a high incidence.LAI's Tongyuan acupuncture method believes that tinnitus is nothing more than the two ends of deficiency and excess.The deficiency is closely related to original spirit,and the excess is related to the pathological factors such as externally-contracted six pathogenic factors,phlegm-damp and blood stasis,and qi stagnation and yang constraint.The Tongyuan acupuncture method is based on original spirit,takes the two vessels of conception vessel(CV)and governor vessel(GV)as the general outline,takes the regulation of yin and yang as the main method,pays attention to the combination of local and overall,and emphasizes the application of tonification and purgation,and has the clinical effect of reinforcing healthy qi and dispelling pathogen,cultivating the vital essence.In clinical application,the method of'unblocking governor vessel and nourishing spirit'is used to play the role of heart and brain nourishing spirit and warming and supporting yang qi.The method of'conducting qi back to its source'has the effect of cultivating the vital essence and regulating qi movement.The treatments should be cooperated according to the syndromes,so that the pathogens can be expelled and healthy qi can be settled.Qi and blood have origins of generation and transformation and normally nourishing in the ear,so as to effectively alleviate the patient's tinnitus symptoms.This paper summarizes and analyzes Professor LAI Xin-Sheng's Experience in the diagnosis and treatment of tinnitus by Tongyuan acupuncture method,and provides a new acupuncture treatment plan for clinical application.

Objective To investigate the clinical efficacy of modified Banxia Houpu Decoction plus Deanxit for the treatment of cancer-related depression(CRD)of phlegm blended with qi type.Methods Sixty-four CRD patients with phlegm blended with qi type were randomly divided into the treatment group and the control group,with 32 patients in each group.The control group was given oral use of Deanxit,and the treatment group was treated with modified Banxia Houpu Decoction plus Deanxit orally.The course of treatment covered 4 weeks.The changes of Karnofsky Performance Status(KPS)scores,self-rating depression scale(SDS)scores,and traditional Chinese medicine(TCM)syndrome scores in the two groups were observed before and after the treatment.Moreover,the efficacy for improving KPS scores and TCM syndrome efficacy in the two groups were also evaluated.Results(1)After 4 weeks of treatment,the total effective rate for improving KPS scores in the treatment group was 90.63%(29/32),and that in the control group was 78.13%(25/32).The intergroup comparison showed that the efficacy for improving KPS scores in the treatment group was significantly superior to that in the control group(P＜0.01).(2)In terms of the efficacy of TCM syndromes,after 4 weeks of treatment,the total effective rate for improving TCM syndrome scores in the treatment group was 87.50%(28/32),and that in the control group was 40.63%(13/32),and the efficacy of TCM syndromes in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the KPS scores in the treatment group were significantly increased compared with those before treatment(P＜0.05),and the KPS scores in the control group tended to increase compared with those before treatment,but the difference was not statistically significant(P＞0.05).The intergroup comparison showed that the effect on increasing KPS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the SDS scores in the two groups were lower than those before treatment(P＜0.05),and the effect on lowering SDS scores in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the TCM syndrome scores of the two groups were lower than those before treatment(P＜0.05),and the effect on lowering TCM syndrome scores in the treatment group was significantly superior to that in the control group(P＜0.05).Conclusion Modified Banxia Houpu Decoction plus Deanxit exerts certain effect for the treatment of CRD of phlegm blended with qi type.The combined therapy can effectively improve the depression mood and quality of life of the patients,and its efficacy is superior to that of Deanxit alone.

Purpose: This study evaluated the value of contrast-enhanced ultrasonography (CEUS) in the ultrasound-guided microwave ablation (MWA) treatment of symptomatic focal uterine adenomyosis. Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA. The non-perfused volume (NPV) was compared between CEUS and dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) following ablation. Therapeutic efficacy and safety were evaluated at 3-, 6-, and 12-month follow-ups. Additionally, this study explored the correlations between pre-treatment CEUS features and a volume reduction ratio indicating sufficient ablation, defined as 50% or more at the 3-month follow-up. Results: No significant differences in NPV were noted between CEUS and DCE-MRI immediately after MWA and during follow-up (all P>0.05). At the 3-month follow-up, the median VRRs for the uterus and adenomyosis were 33.2% and 63.9%, respectively. Sufficient ablation was achieved in 69.2% (36/52) of adenomyosis cases, while partial ablation was observed in the remaining 30.8% (16/52). The identification of non-enhancing areas on pre-treatment CEUS was associated with sufficient ablation (P=0.016). At the 12-month follow-up, significant decreases were observed in both the uterine and adenomyosis volumes (all P<0.001). Dysmenorrhea and menorrhagia were significantly alleviated at 12 months, and no major complications were encountered. Conclusion CEUS can be used to evaluate the ablation zone of focal adenomyosis that has been treated with MWA, similarly to DCE-MRI. The identification of non-enhancing areas on pretreatment CEUS indicates satisfactory treatment outcomes.

Objectives: To analyze the long-term survival of patients with localized renal cell carcinoma after partical nephrectomy. Methods: The clinicopathological records and survival follow-up data of 2 046 patients with localized renal cell carcinoma, who were treated with partial nephrectomy from August 2001 to February 2021 in the Department of Urology, Sun Yat-sen University Cancer Center, were retrospectively analyzed. There were 1 402 males and 644 females, aged (M(IQR)) 51 (19) years (range: 6 to 86 years). The primary end point of this study was cancer-specific survival. Survival curves were estimated using the Kaplan-Meier method, and the difference test was performed by Log-rank test. Univariate and multivariate Cox analysis were fitted to determine factors associated with cancer-specific survival. Results: The follow-up time was 49.2 (48.0) months (range: 1 to 229 months), with 1 974 patients surviving and 72 dying. The median cancer-specific survival time has not yet been reached. The 5- and 10-year cancer specific survival rates were 97.0% and 91.2%, respectively. The 10-year cancer-specific survival rates for stage pT1a (n=1 447), pT1b (n=523) and pT2 (n=58) were 95.3%, 81.8%, and 81.7%, respectively. The 10-year cancer-specific survival rates of patients with nuclear grade 1 (n=226), 2 (n=1 244) and 3 to 4 (n=278) were 96.6%, 89.4%, and 85.5%, respectively. There were no significant differences in 5-year cancer-specific survival rates among patients underwent open, laparoscopic, or robotic surgery (96.7% vs. 97.1% vs. 97.5%, P=0.600). Multivariate analysis showed that age≥50 years (HR=3.93, 95%CI: 1.82 to 8.47, P<0.01), T stage (T1b vs. T1a: HR=3.31, 95%CI: 1.83 to 5.99, P<0.01; T2+T3 vs. T1a: HR=2.88, 95%CI: 1.00 to 8.28, P=0.049) and nuclear grade (G3 to 4 vs. G1: HR=2.81, 95%CI: 1.01 to 7.82, P=0.048) were independent prognostic factors of localized renal cell carcinoma after partial nephrectomy. Conclusions: The long-term cancer-specific survival rates of patients with localized renal cancer after partial nephrectomy are satisfactory. The type of operation (open, laparoscopic, or robotic) has no significant effect on survival. However, patients with older age, higher nuclear grade, and higher T stage have a lower cancer-specific survival rate. Grasping surgical indications, attaching importance to preoperative evaluation, perioperative management, and postoperative follow-up, could benefit achieving satisfactory long-term survival.

Objective:To study the efficacy and safety of EndoClot polysaccharide hemostatic system (EndoClot PHS) for heparinized arterial hemorrhage of upper digestive tract (Forrest Ⅰa) in animal model.Methods:Twelve experimental pigs were randomly divided into the test group ( n=6) and the control group ( n=6) by simple random grouping method. Gastric arterial hemorrhage models were established. Endoclot PHS and Hemospray were used to spray on the wound to stop bleeding in the test group and the control group respectively. The time of effective hemostasis, the amount of hemostatic particles used, and the blockage of the powder feeding tube and its replacement were compared between the two groups. The survival and complications of experimental pigs were observed after the operation. In 10 days after the operation, the experimental pigs were euthanized for pathological dissection. Results:Spurting or pulsatile bleeding was achieved in all experimental pigs. There were significant differences in the time of effective hemostasis (8.75±0.84 min VS 9.83±0.62 min, t=-2.53, P=0.030) and the amount of hemostatic particles used to achieve effective hemostasis (6.71±0.39 g VS 14.10±1.62 g, t=-10.86, P<0.001) between the test group and the control group. There was no significant difference in the occurence of clogging or the replacement of powder feeding pipes between the two groups (0.64±0.02 times VS 0.67±0.04 times, t=-1.64, P=0.131). In addition, the gas source of the test group was stable, and the visual field under the endoscope was clear. Neither the test group nor the control group had gastric lesions, perforation, or embolism. The blood glucose, blood routine, and liver and kidney functions were normal, and no thrombosis or embolism of the main organs occurred in either group. Conclusion:EndoClot PHS is safe and effective for heparinized upper gastrointestinal arterial hemorrhage (Forrest Ⅰa) in animal models.
