Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

Temporomandibular joint osteoarthritis is a common chronic degenerative disease,in which joint pain is the most signif-icant symptom,but its pathogenesis is still unclear.Significant subchondral bone lesions can occur in the early stage of osteoarthritis progression,and more and more experimental evidence shows that subchondral bone lesions play an important role in the pain caused by osteoarthritis.Osteoclasts,osteocytes,osteoblasts,endothelial cells,new generating nerves and blood vessels in the sub-chondral bone matrix microenvironment interact with each other and participate in the process of osteoarthritis pain.Therefore,regu-lating the subchondral bone matrix microenvironment is expected to become a new strategy to control joint pain.

Objective To explore the effect of transcutaneous auricular vagus nerve stimulation(taVNS)combined with dual-task training(DTT)on upper limb function recovery in patients with ischemic stroke.Methods From January to October,2024,60 ischemic stroke patients with upper limb dysfunction admitted to Zhejiang Rehabilitation Medical Center were selected and randomly divided into control group(n=30)and observation group(n=30).Both groups received conventional rehabilitation training.The control group underwent sham-taVNS combined with DTT,while the observation group received active taVNS combined with DTT,for four weeks.Before and after treatment,they were assessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Action Research Arm Test(ARAT),modified Barthel Index(MBI)and motor-evoked potential(MEP)tests.Results The FMA-UE scores,ARAT scores,MBI scores,MEP amplitude and MEP latency improved in both groups af-ter treatment(|t|>3.670,P<0.01),and were superior in the observation group than in the control group(|t|>3.081,P<0.01).Conclusion The combination of taVNS and DTT can significantly improve upper limb function,enhance activities of daily living,and promote neurological recovery in patients with ischemic stroke.

Magnetic stimulation has made significant strides in the treatment of psychiatric disorders. Nonetheless, current magnetic stimulation techniques lack the precision to accurately modulate specific nuclei and cannot realize deep brain magnetic stimulation. To address this, we utilized superparamagnetic iron oxide nanoparticles as mediators to achieve precise targeting and penetration. We investigated the effects of magnetic fields with varying frequencies on neuronal activity and compared the activation effects on neurons using a 10-Hz precise magneto-stimulation system (pMSS) with repetitive transcranial magnetic stimulation in mice. Oxytocin levels, dendritic morphology and density, and mouse behavior were measured before and after pMSS intervention. Our findings suggest that pMSS can activate oxytocinergic neurons, leading to upregulation of oxytocin secretion and neurite outgrowth. As a result, sociability was rapidly improved after a one-week pMSS treatment regimen. These results demonstrate a promising magneto-stimulation method for regulating neuronal activity in deep brain nuclei and provide a promising therapeutic approach for autism spectrum disorder.

Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma（ACB）.Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males，with an average age of（61.3 ± 11.5）years. Twelve patients had comorbidities（6 hypertension，2 coronary heart disease，5 diabetes mellitus，and 3 cerebrovascular diseases）and 12 had a smoking history. The mean body mass index（BMI）was（24.8 ± 3.2）kg/m 2. The maximum tumor diameter measured by enhanced computed tomography（CT）was（29.7 ± 12.7）mm. The preoperative neutrophil-to-lymphocyte ratio（NLR）was 3.4 ± 3.2，and the systemic immune-inflammation index（SII）was（582 ± 496）× 10 9/L.Patients were divided into two groups according to the surgical approach：the radical cystectomy group（ n = 23）and the bladder-sparing group（ n = 10）. For the radical cystectomy group，there were 19 males and 4 females，with a mean age of（59.9 ± 12.6）years. Five patients had comorbidities（3 hypertension，1 coronary heart disease，1 diabetes mellitus，and 2 cerebrovascular diseases）. Eight patients had a smoking history，with a mean BMI of（25.2 ± 3.5）kg/m 2. The maximum tumor diameter was（33.6 ± 10.9）mm，the preoperative NLR was 3.5 ± 3.5，and the SII was（618 ± 558）× 10 9/L. For the bladder-sparing group，there were 9 males and 1 female，with a mean age of（64.5 ± 8.2）years. Seven patients had comorbidities（3 hypertension，1 coronary heart disease，4 diabetes mellitus，and 1 cerebrovascular diseases）. Four patients had a smoking history，with a mean BMI of（23.5 ± 2.3）kg/m 2. The maximum tumor diameter was（20.7 ± 12.5）mm，the preoperative NLR was 3.1 ± 2.2，and the SII was（501 ± 323）× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities（ P = 0.008）and maximum tumor diameter（ P = 0.006），while no significant differences were found in other data（ P > 0.05）. The Kaplan-Meier survival curve was drawn，and Cox regression was used to analyze the prognostic factors of progression-free survival（PFS）and overall survival（OS）of patients. Results:Among the 33 patients，low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology，and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases（27.3%），8 cases（24.2%），7 cases（21.2%），and 9 cases（27.3%）respectively. Nine patients received postoperative adjuvant therapy，including 6 with adjuvant chemotherapy，2 with adjuvant chemotherapy combined with radiotherapy，and 1 with adjuvant immunotherapy. In the radical cystectomy group（ n = 23），there were 13 cases of low-grade and 10 cases of high-grade pathological grading，2 cases with positive margins，19 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，1 case of distant metastasis，and 5 patients received adjuvant therapy（4 cases of adjuvant chemotherapy，and 1 case of adjuvant immunotherapy）. In the bladder-sparing group（ n = 10），there were 7 cases of low-grade，3 cases of high-grade pathological grading，1 case with positive margins，3 cases of muscle-invasive bladder adenocarcinoma，zero lymph node or distant metastasis，and 4 patients received adjuvant therapy（2 cases of adjuvant chemotherapy，and 2 cases of combined adjuvant chemotherapy and radiotherapy）. A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups（ P = 0.006），while no significant differences were observed in other data（ P > 0.05）.The median follow-up duration of the patients was 28.0 months，the median PFS was 86.0 months，and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS（ P = 0.777）and OS（ P = 0.585）between the radical cystectomy group and the bladder-preserving group. Female（ P = 0.011），BMI < 25 kg/m2（ P = 0.038），and positive surgical margins（ P < 0.01）were associated with poorer PFS. Aged ≥ 70 years（ P = 0.003），lymph node metastasis（ P = 0.041），and positive surgical margins（ P = 0.025）were associated with poorer OS，and patients in the adjuvant therapy group had better OS（ P = 0.005）. Multivariate Cox regression analysis indicated that positive surgical margins（HR 10.2， P = 0.012）were an independent impact factor for PFS，and positive surgical margins（HR 39.8， P = 0.001）and adjuvant therapy（HR 0.12， P = 0.021）were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.

Objective To investigate the protective effects of butyrate on sepsis-related myocardial dys-function.Methods Thirty healthy 8-week-old male Sprague-Dawley rats were randomly divided into three groups:sham operation group(SH,n=10),sepsis group(CL,n=10),and butyrate group(BU,n=10).The CL and BU groups underwent cecal ligation and puncture(CLP)to establish sepsis models,while the SH group received the same surgical procedure without cecal ligation or puncture.Within 30 minutes post-opera-tion,the SH and CL groups received 5 mL normal saline via gavage,whereas the BU group was administered 5 mL sodium butyrate solution(500 mg/kg)in normal saline.Cardiac output(CO)and ejection fraction(EF)were compared among the three groups.Myocardial histopathological injury was assessed by HE staining,and mitochondrial ultrastructural damage was observed by electron microscopy.Serum levels of brain natriuretic peptide(BNP),cardiac troponin Ⅰ(cTnⅠ),and butyrate were compared among groups.Western blot analysis was performed to detect and compare the expression levels of long-chain acyl-CoA synthetase 4(ACSL4)and glutathione peroxidase 4(GPX4)in myocardial tissues.Results After intervention,the BNP and cTnⅠ levels in the CL group were higher than those in the SH group,while CO and EF were lower than those in the SH group(P＜0.05).The BNP and cTnⅠ levels in the BU group were lower than those in the CL group,whereas CO and EF levels were higher than those in the CL group(P＜0.05).HE staining of myocardial tissues re-vealed more severe inflammatory cell infiltration and myocardial cell edema in the CL group compared with the SH group,while the BU group showed reduced inflammatory cell infiltration.Mitochondrial membrane in-tegrity was impaired in the CL group manifested by unclear cristae,swelling,vacuolar degeneration and rup-ture,whereas mitochondrial damage was attenuated in the BU group.Serum butyrate levels were measured as(61.7±21.6)μg/mL,(95.3±16.6)μg/mL and(302.2±49.7)μg/mL in the CL,SH and BU groups respec-tively(P＜0.05).The ACSL4 expression in the CL group was higher than that in the SH group,while GPX4 protein expression was lower than that in the SH group(P＜0.05).The BU group exhibited lower ACSL4 expression and higher GPX4 protein expression compared with the CL group(P＜0.05).Conclusion Buty-rate can ameliorate myocardial injury in septic rats,and its protective effect may be associated with the inhibi-tion of myocardial ferroptosis.

Objective:To investigate the safety and efficacy of flow diverter (FD) in the treatment of middle cerebral artery (MCA) dissection aneurysms.Methods:Patients with MCA dissection aneurysm received FD treatment at the Department of Neurosurgery, Jinjiang Hospital and the Cerebrovascular Disease Center of the First Affiliated Hospital of Naval Medical University from January 2021 to December 2023 were included retrospectively. The success rate of procedure, incidence of complications, occlusion rate of aneurysms, and clinical outcome were evaluated.Results:A total of 23 patients were included, with a success rate of 100% for FD implantation and a periprocedural complication rate of 8.7%. Nineteen patients (82.6%) completed angiography follow-up within an average of 7.2 months, of which the aneurysms of 16 patients (84.2%) were completely occluded, 3 (15.8%) were partial occluded, and 2 (10.5%) experienced in-stent restenosis; 14 (73.7%) showed stenosis of covered branch openings, of which 2 (10.5%) had branch occlusions, with no relevant clinical symptoms. The median clinical follow-up time was 23.2 months, with 95.7% of patients achieving good outcome (modified Rankin scale score ≤2).Conclusion:FD is safe and effective in the treatment of MCA dissection aneurysms, and precise device selection and release is the key to improving procedural safety.

Objective To explore the effect of transcutaneous auricular vagus nerve stimulation(taVNS)combined with dual-task training(DTT)on upper limb function recovery in patients with ischemic stroke.Methods From January to October,2024,60 ischemic stroke patients with upper limb dysfunction admitted to Zhejiang Rehabilitation Medical Center were selected and randomly divided into control group(n=30)and observation group(n=30).Both groups received conventional rehabilitation training.The control group underwent sham-taVNS combined with DTT,while the observation group received active taVNS combined with DTT,for four weeks.Before and after treatment,they were assessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Action Research Arm Test(ARAT),modified Barthel Index(MBI)and motor-evoked potential(MEP)tests.Results The FMA-UE scores,ARAT scores,MBI scores,MEP amplitude and MEP latency improved in both groups af-ter treatment(|t|>3.670,P<0.01),and were superior in the observation group than in the control group(|t|>3.081,P<0.01).Conclusion The combination of taVNS and DTT can significantly improve upper limb function,enhance activities of daily living,and promote neurological recovery in patients with ischemic stroke.
