ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ(CaMKⅡ)/cAMP-response element binding protein (CREB) signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet, intraperitoneal injection of isoproterenol (ISO), and chronic unpredictable mild stress (CUMS). A total of 108 SD male rats were randomly divided into normal group, model group, high (23.4 g·kg-1), medium (11.7 g·kg-1), and low (5.85 g·kg-1) dose groups of modified Chaihu Shugansan, CaMKⅡ inhibitor (KN93) group, and KN93 + high, medium, and low dose groups of modified Chaihu Shugansan, with 12 rats in each group. From the first day of modeling to the end of modeling, drugs were administered once a day. In the seventh and eighth weeks, the KN93 group and the KN93 + high, medium, and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week, behavioral tests including sucrose preference, open field, and elevated plus maze were conducted. Electrocardiogram (ECG) lead Ⅱ changes were observed in each group of rats, and hematoxylin-eosin (HE) staining was performed to observe changes in heart tissue. Serum levels of triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and lactate dehydrogenase (LDH) were measured by using an enzyme-labeled instrument. Creatine kinase (CK) and creatine kinase-MB (CK-MB) were detected by ultraviolet spectrophotometry, while serum monocyte chemoattractant protein-1 (MCP-1) was measured by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue, and Western blot was performed to assess protein expression of CaMKⅡ, phosphorylated (p)-CaMKⅡ, CREB, and p-CREB. ResultsCompared to the normal group, the model group showed significant reductions in sucrose preference rate, total activity distance in the open field, number of entries into the center area of the open field, and percentage of entries into the open arms of the elevated plus maze (P<0.01). The ECG showed ST-segment elevation, and HE staining showed serious degeneration of myocardial fibers, disordered arrangement, and infiltration of a large number of inflammatory cells. In addition, serum TC and LDL levels increased (P<0.01), and HDL level decreased (P<0.01). CK, CK-MB, LDH, and MCP-1 levels significantly increased (P<0.05, P<0.01). The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue (P<0.05, P<0.01), but those increased in the heart tissue (P<0.01). Compared to the model group, the high, medium, and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference, total activity distance in the open field, number of entries into the center area of the open field, and percentage of entries into the open arms of the elevated plus maze (P<0.01), as well as decreased serum CK, CK-MB, LDH, and MCP-1 levels (P<0.05, P<0.01). KN93 also reduced ST-segment elevation, alleviated the degeneration degree of myocardial fibrosis, and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced (P<0.05, P<0.01). The KN93 + high, medium, and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression, possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway, with the high-dose modified Chaihu Shugansan showing the best effects.

OBJECTIVE:
The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture.
METHODS:
Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve.
RESULTS:
Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats.
CONCLUSION
Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

Objective Visual electrophysiology and optical correlation tomography angiography(OCTA)were used to investigate differences in preoperative retinal function in patients with type 2 diabetic cataract(DC)without obvious retinopathy(NDR)and to determine the clinical application of whole-process blood glucose man-agement(WBGM)for improving postoperative vision in DC patients.Methods This study investigated the preop-erative and postoperative visual electrophysiology(N75,P100,photopic FERG,and scotopic FERG),peripapil-lary retinal nerve fiber layer(pRNFL)and peripapillary capillary vessel density(ppVD)data,as well as trends in these data changes during blood glucose management intervention.Results As the course of T2DM progressed,FBG and HbA1c increased,the N75 and P100 lategraduancy periods of patients gradually lengthened,and the photopic FERG,scotopic FERG,pRNFL,and ppVD values decreased at each postoperative time point.At the same time,the best corrected visual acuity(BCVA)of patients after surgery gradually decreased(P<0.05).Compared with that at 1 week after surgery,the BCVA of Group A(without whole-process blood glucose manage-ment)gradually increased at 1 month and 3 months after surgery but showed a downward trend at 1 year after sur-gery.The BCVA of Group B(with whole-process blood glucose management)gradually stabilized at 1 month after surgery,and at all time points after surgery,the BCVA of Group B was better than that of Group A.The results showed that N75 and P100 in Group A were greater than those in Group B,while the photopic and scotopic FERG,pRNFL,and ppVD(%)in Group A were lower than those in Group B.In addition,N75 and P100 in Group A showed a gradual prolongation trend at various time points after surgery,while photopic FERG,scotopic FERG,pRNFL,and ppVD(%)showed a gradually decreasing trend.However,the above data in Group B gradu-ally stabilized at 3 months after DC surgery,approaching the preoperative level of the group(P<0.05).In the state of whole blood glucose management,although N75 and P100 both reached their longest durations at 1 week af-ter surgery,N75,P100,photopic FERG,scotopic FERG,and pRNFL showed a gradually decreasing trend at 1 month and 3 months after surgery,while ppVD(%)gradually increased(P<0.05).At various time points from 3 months to 1 year after surgery,the overall trend of the above indicators remained stable and close to the preoperative values(P>0.05).Conclusion According to the results of the quantitative analysis of visual electrophysiology and OCTA,in DC patients without obvious retinopathy and with the worsening of diabetes,retinal function decreased,but whole-process blood glucose management effectively restored retinal function and improved visual quality after surgery.

Objective:To evaluate the feasibility of using a visual positioning system for both motion phantom and clinical quality control.Methods:A phantom experiment was conducted using the Dynamic Thorax Phantom from CIRS. Different ranges of motion were simulated to assess the discrepancies between camera-recorded positions and actual movements. Visual markers were also attached to the treatment bed and the collimator head, and their movements were simulated as part of the experiment. The experiment was repeated for three times. Discrepancies between system measurements and manual measurements were recorded and analyzed to assess the accuracy and reliability of the system.Results:In the motion phantom test, the deviation between the actual motion distance of the phantom and the system's recorded measurement was (0.18±0.07) mm. For linear motion analysis along the X, Y, and Z axes on the treatment table, the measurement errors were (0.14±0.08) mm, (0.15±0.09) mm, and (0.16±0.08) mm, respectively. Additionally, the measurement error in the rotational direction of the treatment couch was 0.18°±0.09°. For the rotational direction of the collimator head, the measurement error was 0.11°±0.02°. Conclusion:The system demonstrates good accuracy and stability, and has potential clinical application value.
