Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions （Second Batch）. This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution， efficacy， indications， dosage decoctions， and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty， but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma， 619.5 g of Puerariae Lobatae Radix， 413 g of Paeoniae Radix Alba， and 413 g of Glycyrrhizae Radix et Rhizoma， which are ground into coarse powder. Each dose is 12.39 g， and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome， penetrating pathogenic factors， and detoxicating together. Its indications are widely involved in internal medicine， pediatrics， surgery， ophthalmology and otorhinolaryngology， obstetrics and gynecology， sexually transmitted diseases， and other diseases， such as measles， sores， acne， spots， surgical gangrene， red eyes， toothache， chancre， and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated， including rash， pox， macula， numbness， summer diarrhea， dysentery， sha disease， febrile symptoms， spring warmth， winter warmth， and cold pestilence. At the same time， it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications， it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system， nervous system， pediatric-related diseases and syndromes， skin system， hepatobiliary system， and digestive system. It plays a key role in the treatment of epidemic diseases such as measles， chronic hepatitis B， dysentery， and tetanus.

OBJECTIVE To establish the fingerprint of Bushen ningshen ointment， determine the contents of its major constituents， and investigate its in vitro antioxidant activity. METHODS High performance liquid chromatography （HPLC） fingerprints of 10 batches of Bushen ningshen ointment were established. Similarity evaluation and identification of common peaks were subsequently performed. The contents of 10 components such as salidroside were determined using the same HPLC method. Using the scavenging rates against 2，2′-azino bis（3-ethylbenzothiazoline-6-sulfonic acid） （ABTS） and 1，1-diphenyl-2- picrylhydrazyl （DPPH） radicals， as well as ferric ion reducing antioxidant power （FRAP） as indicators， the anti-oxidant activity of the ointment was evaluated； grey relational analysis and partial least squares regression were conducted using SIMCA 14.1 software to establish the spectrum-effect relationship. RESULTS The fingerprint chromatogram of 10 batches of Bushen ningshen ointment contained 24 common peaks， with similarity values all exceeding 0.96. Eleven peaks were identified as adenosine （peak 1）， salidroside （peak 4）， morroniside （peak 6）， catechin （peak 7）， paeoniflorin （peak 10）， spinosin （peak 11）， ferulic acid （peak 12）， isoquercitrin （peak 13）， E-mail：wli1743@163.com verbascoside （peak 14）， paeonol （peak 23）， and emodin （peak 24）. Content determination results showed that the average contents of salidroside， morroniside， catechin， paeoniflorin， spinosin， ferulic acid， isoquercitrin， verbascoside， paeonol， and emodin were 0.725， 1.962， 0.214， 3.395， 0.124， 0.107， 0.286， 0.019， 0.034 and 0.067 mg/g， respectively. The antioxidant potency composite index （APC） for the 10 batches ranged from 85.08% to 96.35%. Spectrum-effect relationship analysis indicated that all 24 common peaks were positively correlated with the antioxidant capacity. Seventeen peaks had variable importance in projection values ＞1， specitically peaks 2， 5， 6， 7， 9， 10， 13- 21， 23， and 24. CONCLUSIONS This study successfully established the HPLC fingerprint and content determination method for Bushen ningshen ointment. The compounds represented by the 17 common peaks such as morroniside may be the active components contributing to its antioxidant effects.

Objective To investigate the value of split-bolus dual-phase contrast-enhanced computed tomography (CT) in preoperative staging of clear cell renal cell carcinoma (ccRCC), and to analyze its effect on radiation dose. Methods From June 2021 to July 2024, 118 patients with suspected renal space occupying lesions admitted to Changsha Fourth Hospital were initially selected. Using a random number table, these patients were assigned to a single-bolus group (single-bolus three-phase enhancement program) and a split-bolus group (split-bolus dual-phase enhancement program), with 59 patients in each group. According to the postoperative pathological results, 100 patients with ccRCC were selected as the study subjects, including 48 patients in the single-bolus group and 52 patients in the split-bolus group. The CT values of ccRCC tissues in various phases were compared between the two groups. The accuracy of preoperative ccRCC staging was analyzed using postoperative pathological staging as the gold standard, and the effective dose (ED) was compared between the two groups. Results There was no significant difference in ccRCC staging between the two groups (P > 0.05). The CT value in the parenchyma-excretion phase of the split-bolus group was (88.24 ± 18.34) HU, which was lower than that of the single-bolus group in the parenchyma phase [(102.43 ± 20.66) HU, P < 0.05]. The accuracy of preoperative staging of ccRCC was 86.54% in the split-bolus group, which was not significantly different from 87.50% in the single-bolus group (P > 0.05). The mean ED was (14.54 ± 1.42) mSv in the split-bolus group, which was lower than (20.43 ± 1.18) mSv in the single-bolus group (P < 0.05). Compared with the single-bolus group, the ED of the split-bolus group decreased by 28.83%. Conclusion Split-bolus dual-phase contrast-enhanced CT provides similar accuracy compared to single-bolus CT in evaluating the preoperative staging of ccRCC, and can reduce the radiation dose.

OBJECTIVE: To explore the improvement effect of electroacupuncture (EA) based on Xingnao Kaiqiao acupuncture (acupuncture for regaining consciousness and opening orifices) on cognitive impairment in mice with Parkinson's disease (PD), and to explore its regulatory mechanisms on the kinesin family member 5A (KIF5A)/mitochondrial Rho GTPase 1 (Miro1) pathway and mitophagy in prefrontal cortical neurons. METHODS: A total of 70 male C57BL/6J mice of clean grade were randomly divided into a normal group (12 mice), a sham operation group (12 mice), and a model pre-screening group (46 mice). Unilateral stereotaxic injection of 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle was adopted to establish the PD model in the model pre-screening group. Twenty-four mice after successful modeling were randomly selected and divided into a model group and an EA group, 12 mice in each one. In the EA group, acupuncture was applied at "Shuigou" (GV26) and bilateral "Sanyinjiao" (SP6) and "Neiguan" (PC6), ipsilateral "Sanyinjiao" (SP6) and "Neiguan" (PC6) were connected to EA respectively, with disperse-dense wave, 5 Hz/20 Hz in frequency, 0.5 mA in current intensity, 20 min a time, 6 times a week for 30 days. Cognitive function was assessed by Y-maze and Morris water maze tests; morphology of prefrontal cortex was observed by H.E. staining; reactive oxygen species (ROS) level in prefrontal cortex was detected by fluorescence probe method; mitochondrial morphology and autophagosome ultrastructure were observed by transmission electron microscopy; the mRNA expression of tyrosine hydroxylase (TH) was detected by quantitative real-time PCR; the protein expression of TH, KIF5A, Miro1, p62, Parkin and PTEN induced kinase 1 (PINK1) was detected by Western blot. RESULTS: Compared with the sham operation group, both the model group and the EA group exhibited increased rotation number of per minute (P<0.001). Compared with the sham operation group, in the model group, the novel arm exploration time of Y-maze test was shortened (P<0.001), the escape latency of Morris water maze test was prolonged (P<0.05) and the platform crossing number of Morris water maze test was reduced (P<0.01); in the prefrontal cortex, the number of cellular vacuole and neurons with karyopyknosis was increased (P<0.001), and mitochondrial autophagosomes could be observed; in the prefrontal cortex, the relative expression of ROS was increased (P<0.001), the protein and mRNA expression of TH was decreased (P<0.001), the protein expression of Miro1, PINK1, Parkin was increased (P<0.001, P<0.01), the protein expression of KIF5A and p62 was decreased (P<0.001). Compared with the model group, in the EA group, the novel arm exploration time of Y-maze test was prolonged (P<0.01), the escape latency of Morris water maze test was shortened (P<0.05) and the platform crossing number of Morris water maze test was increased (P<0.05); in the prefrontal cortex, the number of cellular vacuole and neurons with karyopyknosis was decreased (P<0.001), and the number of mitochondrial autophagosomes reduced and the mitochondrial morphology was improved; in the prefrontal cortex, the relative expression of ROS was decreased (P<0.01), the protein and mRNA expression of TH was increased (P<0.001, P<0.01), the protein expression of Miro1, PINK1, Parkin was decreased (P<0.001, P<0.01, P<0.05), the protein expression of KIF5A and p62 was increased (P<0.01, P<0.05). CONCLUSION Xingnao Kaiqiao electroacupuncture effectively alleviates cognitive impairment and damage of neuronal function in PD mice, its mechanism may be related to the regulation of KIF5A/Miro1 pathway, hence reducing the mitophagy in prefrontal cortical neurons.

Lophatheri Herba and Gypsum Fibrosum in the prescription could clear away heat and relieve vexation. Ginseng Radix et Rhizoma，Ophiopogonis Radix， Ginseng Radix et Rhizoma， and Oryza sativa could promote body fluid production and invigorate Qi. Pinelliae Rhizoma could harmonize the stomach and stop vomiting. The prescription had stable compatibility and had the effects of clearing away heat， relieving vexation， invigorating Qi， promoting body fluid production， and harmonizing the stomach. Zhuye Shigaotang was widely applied in modern clinical practices， with high application frequency in the digestive system， pediatric-related diseases， respiratory system， infectious diseases， circulatory system， and neuropsychiatric system. The specific symptoms included recurrent aphtha， hiccup， infantile pneumonia， infantile summer fever， unexplained fever， upper respiratory tract infection， epidemic hemorrhagic fever， and late measles.

Objective:To explore the effects of the LAmbre device and mitral annulus(MA), as well as left atrium(LA) in patients with non-valvular atrial fibrillation(NVAF) after left atrial appendage closure (LAAC) using real-time-three-dimensional transesophageal echocardiography (3D TEE).Methods:Fity-six consecutive patients who underwent LAAC with the LAmbre device in Zhongshan Hospital of Fudan University from June 2019 to March 2023 were retrospectively enrolled, with no or less than moderate mitral regurgitation (MR). All patients underwent pre-operative and follow-up two-and three-dimensional transesophageal echocardiography (2D TEE, 3D TEE) at 60 days after the operation. The quantitative parameters of MA and LA were obtained by offline analysis using QLab 13.0 (Philips Healthcare, Andover, MA). Importantly, mitral annular measurements were made at seven time points throughout the cardiac cycle: early diastole, mid-diastole, late diastole, mitral valve closure, early systole, mid-systole, and late systole, which facilitates constructing the dynamic model of MA to assess the annular morphology and dynamics.Results:The values of AP diameter (APD), AL-PM diameter (ALPMD), 3D annulus circumference (3DAC), 3D annulus area (3DAA) decreased significantly compared with pre-operative values at all time points of the cardiac cycle (all P<0.05), while non-planar angle (NPA) and AH/CD were not apparently changed (all P>0.05 ). Throughout the cardiac cycle, MA showed regular changes, gradually increased in systole with the saddle shape deepened, and gradually decreased in diastole with the saddle shape shallowed.During systole, there was an increase in the rate of change of AP in MA [pre-operative (3.01±2.64)%, post-operative (3.81±3.51)%, P=0.037] after LAAC, with no significant difference in the rate of change of ALPM, 3DAC, and 3DAA.Meanwhile, we observed an evident reduction in LA minimal volume (LAVmin) [pre-operative (78.36±25.16)ml, post-operative (70.73±22.78)ml, P=0.004] and an obvious increase in LA ejection function [pre-operative (22.88±10.09)%, post-operative (31.41±12.28)%, P<0.05] during follow-up. Conclusions:3D TEE can accurately assess the impact of LAAC on the MA and LA. The LAmbre device can affect the morphology of MA, as well as the structure and function of LA, while the change of the dynamics of MA is not so prominent.

ObjectiveTo analyze the expression of molecular marker affecting the prognosis of acute myeloid leukemia （AML） patients from bioinformatics database， thus providing an experimental basis for further exploration of a novel molecular marker for the prognosis of AML. MethodsThe prognostic data of 179 AML patients from The Cancer Genome Atlas （TCGA） database were examined for differential gene analysis and survival analysis. The bone marrow samples of 74 healthy individuals （HI） and 542 de novo AML patients in the dataset GSE13159 downloaded from the Gene Expression Omnibus （GEO） database were analyzed to detect the difference in the expression levels of differential target genes. Peripheral blood and bone marrow samples were collected from 18 de novo AML patients and 20 age- and gender-matched healthy controls， and real-time fluorescent quantitative PCR was used to validate the expression levels of the differential genes in the AML patients. ResultsBioinformatics data analysis showed that the optimal cut-off value of Homo sapiens NK2 homeobox 3 （NKX2-3） calculated by R language was 0.051. Survival analysis revealed a statistically poorer overall survival in de novo AML patients with high NKX2-3 expression than in those with low NKX2-3 expression （P = 0.0036）. NKX2-3 was highly expressed in patients with de novo AML than in HI and the difference was statistically significant （P < 0.001）. Real-time fluorescence quantitative PCR verified the expression levels of the NKX2-3 gene in AML patients and confirmed that compared with those in HI， in the de novo AML patients， NKX2-3-1 and NKX2-3-2 were highly expressed and were significantly correlated （P = 0.000， P = 0.000）. ConclusionNKX2-3 is highly expressed in de novo AML patients， and the AML patients with high NKX2-3 expression have poor overal survival. NKX2-3 may be closely related to the clinical outcome and prognosis of AML.

Objective To explore the mechanisms of Buyang Huanwu Decoction(BYHWD)in reducing oxidative stress levels to protect the blood-brain barrier(BBB)in cerebral ischemia/reperfusion injury(CIRI)rats.Methods A middle cerebral artery occlusion/reperfusion(MCAO/R)model in rats was established via wire embolization method.PeriCam PSI laser speckle flow imaging was applied to detect whether the model was successfully established.Neurological deficits in the rats were evaluated by Zea Longa score,and histopathological changes in the rat brain were observed by HE staining.The degree of brain edema was detected by the dry and wet weight method.BBB permeability was detected by Evans blue staining,and ultrastructural changes to the BBB were observed by transmission electron microscopy.The levels of ROS,MDA and SOD activities,which are related to oxidative stress,were detected using kits.The expression levels of matrix metalloproteinase-9(MMP-9)were detected by immunohistochemical staining and Western blot.The expression levels of Occludin,ZO-1,and Claudin-5 tight junction proteins were determined via immunofluorescence and Western blot.Results BYHWD reduced neurological deficit scores,alleviated brain histopathological damage,alleviated BBB structural disruption,prolonged the appearance of dense regions in the tight junction structure,attenuated edema of the brain on the ischemic side,and reduced BBB permeability in MCAO/R rats.BYHWD decreased the levels of ROS and MDA,increased the activity of SOD,decreased the expression levels of MMP-9,and increased the expression levels of Occludin,Claudin-5 and ZO-1.Conclusions BYHWD can increase BBB tight junction protein expression levels,reduce the permeability of the BBB,protect the ultrastructure of the BBB,and reduce brain edema,and its mechanisms may be related to its antioxidant activity and inhibition of MMP-9 activation.

Dilated cardiomyopathy(DCM)has a concealed onset with left or even whole heart enlargement as the main imaging manifestation.It is a common primary disease of heart failure and arrhythmia.With the continuous deepening of research in recent years,the intrinsic molecular mechanism of regulatory cell death(RCD)has gradually become clear.Researchers have found that the RCD mode plays a very important role in the occurrence and development of DCM.At present,the RCD modes involved in DCM mainly include apoptosis,necrotic apoptosis,pyroptosis,iron death,autophagy,and cuproptosis,and a certain correlation exists among them,which interact and regulate each other.This article provides an overview of the current research status on the mechanisms of the six RCD modes involved in DCM to provide a reference for future basic research and clinical applications.

According to the Shennong Ben Cao Jing, Alismatis Rhizoma has tonic properties, however, that is not recorded in the Chinese Pharmacopoeia. By reviewing the relevant literature on the efficacy of Alismatis Rhizoma in ancient texts, it was found that before the Song Dynasty, the efficacy of Alismatis Rhizoma included tonic, diuresis, and heat relief. From the Song Dynasty, some medical practitioners questioned the view that Alismatis Rhizoma is a tonic, while the Ming Dynasty medical practitioners believed that the tonic function of Alismatis Rhizoma is derived from its water-relieving effect and that it is not a direct tonic, and the Qing Dynasty medical practitioners believed that the core effect of Alismatis Rhizoma is water-relieving and that tonic is an excessive praise of Alismatis Rhizoma’s effect with no practical clinical significance. By this point, the notion that Alismatis Rhizoma is a tonic has completely dropped out of mainstream traditional Chinese medicine theory. In addition, it was also found that the efficacy of Alismatis Rhizoma in stopping seminal discharge has been documented in medical texts for generations, but not in the Chinese Pharmacopoeia.
