ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective To investigate prognostic value of serum levels of cathepsin B(CTSB)and NADPH oxidase 4(NOX4)in patients with sepsis associated acute kidney injury(S-AKI).Methods A total of 306 pa-tients with sepsis treated to the hospital from June 2023 to June 2024 were selected,including 192 patients with S-AKI(S-AKI group)and 114 patients without S-AKI(non-S-AKI group).According to the prognosis of S-AKI patients,they were divided into poor prognosis group(n=127)and non-poor prognosis group(n=65).The differences of CTSB and NOX4 in different groups were compared.Pearson analysis was conducted to analyze the correlation between CTSB,NOX4 and clinical indicators.The influencing factors of poor prognosis in S-AKI patients was analyzed according to multivariate Logistic regression.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of CTSB and NOX4 on the poor prognosis of S-AKI pa-tients.Results Th e serum levels of CTSB,NOX4 and serum creatinine(SCr)in S-AKI group were signifi-cantly higher than those in non-S-AKI group(P＜0.05),while the mean arterial pressure and oxygenation in-dex were lower than those in non-S-AKI group(P＜0.05).Serum levels of CTSB and NOX4 in patients with sepsis were positively correlated with SCr(P＜0.05).Compared to non-poor prognosis group,the age,SCr,CTSB and NOX4 of patients in the poor prognosis group were higher,while the mean arterial pressure and ox-ygenation index were lower(P＜0.05).The increased mean arterial pressure and oxygenation index were pro-tective factors for poor prognosis in S-AKI patients(P＜0.05),and the increased age,SCr,CTSB and NOX4 levels were risk factors for poor prognosis in S-AKI patients(P＜0.05).ROC curve showed that the area un-der the curve(AUC)of CTSB combined with NOX4 was significantly higher than AUC of single detection of CTSB and NOX4(Z=4.066,P＜0.001,Z=3.801,P＜0.001).Conclusion The serum levels of CTSB and NOX4 in S-AKI patients are elevated,and can indirectly reflect kidney function.CTSB combined with NOX4 can significantly improve the prediction efficiency of poor prognosis in S-AKI patients,which has potential ap-plication value for clinical treatment and nursing.

[Objective[ To analyze the main syndrome types, medication rules, and core prescription characteristics of traditional Chinese medicine (TCM) in the treatment of metabolism-associated fatty liver disease (MAFLD), and to predict the anti-MAFLD mechanism of core formula, so as to provide references for the clinical application of TCM and the development of new drugs. [Methods] Literature research on TCM in treating MAFLD was retrieved from China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang Database since the establishment of the database to July 2022. Excel 2019 and Chinese Medicine Inheritance Computing Platform (V3.0) were used for frequency analysis, association rule analysis, and cluster analysis of effective prescriptions. The key components, targets, and action pathways of anti-MAFLD core formulas were predicted by network pharmacology. Finally, the interactions between the obtained core components and their core targets were verified reversely by molecular docking technology. [Results] A total of 218 articles were screened and selected, including 352 prescriptions, involving 270 traditional Chinese herbs. The drugs were used a total of 3 901 times, and a total of 10 915 cases were collected, among which the prevalence rate was higher in males. The main types of TCM syndrome included intermingled phlegm and blood stasis syndrome, liver depression and spleen deficiency syndrome, and damp-heat in liver and gallbladder syndrome, among which Shanzha (Crataegi Fructus), Danshen (Salviae Miltiorrhizae Radix et Rhizoma), Fuling (Poria), Zexie (Alismatis Rhizoma), Chaihu (Bupleuri Radix), and Baizhu (Atractylodis Macrocephalae Rhizoma) were the most frequently used. The properties of Chinese medicine primarily encompassed thermal characteristics, with a predominant emphasis on cold and warm; the flavors of herbs were predominantly characterized by bitterness and sweetness, while the majority exhibited tropism towards the spleen and liver meridians. The drugs were primarily classified based on their efficacy in tonifying deficiencies, promoting diuresis and moistening, enhancing blood circulation and removing blood stasisheat-clearing, etc. The association rules were employed to derive a set of 20 core drug pairs, while cluster analysis was utilized to identify three distinct groups of core drug combinations. Network pharmacological showed that the main components of the core formula “Shanzha (Crataegi Fructus) - Danshen (Salviae Miltiorrhizae Radix et Rhizoma) - Zexie (Alismatis Rhizoma) - Chaihu (Bupleuri Radix) - Fuling (Poria)” in the treatment of MAFLD were quercetin, apigenin, puerarin, luteolin, ursolic acid, kaempferol, tanshinone IIA, emodin, paeonol, etc., which involved RAC-alpha serine/threonine-protein kinase 1 (AKT1), cellular tumor antigen p53 (TP53), interleukin (IL)-6, IL-1β, signal transducer and activator of transcription 3 (STAT3), epidermal growth factor receptor (EGFR), peroxisome proliferative activated receptor gamma (PPARG), and other key targets. The molecular docking results showed that the core components had good binding to lipid and atherosclerosis, and phosphatidylinositol 3 kinase (PI3K)/AKT signaling pathway-associated proteins. [Conclusion] The main principles of TCM for the treatment of MAFLD involve soothing the liver and strengthening the spleen, eliminating phlegm and dampness, clearing heat and dampness, as well as promoting blood circulation and removing blood stasis. The core formula may exert anti-MAFLD effects mediated through multiple components, targets, and signaling pathways. This study establishes a theoretical foundation for the clinical application of TCM in the treatment of MAFLD, and serves as a reference for further exploration of new drugs against MAFLD.

Objective:To evaluate the left ventricular myocardial work parameters of the animal models with left bundle branch block (LBBB) and evaluate the effects of LBBB on left ventricular function and motion pattern by pressure-strain loops (PSL) of speckle tracking imaging (STI).Methods:In Twenty-four healthy male beagles, LBBB was induced by radio frequency ablation under anesthesia, and blood pressure was measured at the same time. Electrocardiograms and echocardiography images were acquired before (baseline), 30 minutes after (acute-LBBB) and 3 months after(chronic-LBBB) the creation of LBBB respectively. STI was applied to measure the left ventricular global longitudinal strain (GLS) and obtain the the PSL of each time point to evaluate the left ventricular global and segmental myocardial work parameters.Results:Compared to the baseline, the global work efficiencies(GWE) were obviously reduced ( P<0.05) and global wasted works(GWW) were significantly increased ( P<0.01) in the acute-LBBB and chronic-LBBB, significant differences were observed in GLS between acute-LBBB and baseline( P=0.04). In baseline, the work efficiency (WEsept) and the constructive work (CWsept) in the basal and middle segments of the septal wall were both obviously higher than the corresponding segments of left ventricular lateral wall( P<0.01), while the distribution of the wasted work(WWsept) was opposite( P<0.01). In acute-LBBB, the WEsept of all segments were significantly decreased ( P<0.05), the WWsept were obviously increased( P<0.05), the CWsept of basal segment was significantly reduced( P=0.01), while the wasted work in the basal segment of lateral wall(WWlat) was increased( P=0.04) compared with the baseline. Compared with the acute-LBBB, the WEsept of basal and middle segments were mildly recovery( P=0.03) in chronic-LBBB, but were still lower than the baseline ( P=0.001), the changes of the other myocardial work parameters of septal and lateral wall were similar to the acute-LBBB. Conclusions:Both acute-LBBB and chronic-LBBB can lead to the changes of left ventricular global and segmental myocardial work parameters. The myocardial work parameters of left ventricle can quantitatively analyze the changes of left ventricular function and motion pattern of the LBBB.

OBJECTIVE: To compare the mid- and long-term outcomes of patients receiving mitral valve replacement through robotically assisted and conventional median sternotomy approach. METHODS: The data of 47 patients who underwent da Vinci robotic mitral valve replacement in our hospital between January, 2007 and December, 2015 were collected retrospectively (robotic group). From a total of 286 patients undergoing mitral valve replacement through the median thoracotomy approach between March, 2002 and June, 2014, 47 patients were selected as the median sternotomy group for matching with the robotic group at a 1:1 ratio. The perioperative data and follow-up data of the patients were collected, and the quality of life (QOL) of the patients at 30 days and 6 months was evaluated using the Quality of Life Short Form Survey (SF-12). The time of returning to work postoperatively and the patients' satisfaction with the surgical incision were compared between the two groups. RESULTS: All the patients in both groups completed mitral valve replacement successfully, and no death occurred during the operation. In the robotic group, only one patient experienced postoperative complication (pleural effusion); in median sternotomy group, one patient received a secondary thoracotomy for management of bleeding resulting from excessive postoperative drainage, and one patient died of septic shock after the operation. The volume of postoperative drainage, postoperative monitoring time, ventilation time, and postoperative hospital stay were significantly smaller or shorter in the robotic group than in the thoracotomy group ( CONCLUSIONS Robotically assisted mitral valve replacement is safe and reliable. Compared with the median sternotomy approach, the robotic approach is less invasive and promotes faster postoperative recovery of the patients, who have better satisfaction with the quality of life and wound recovery.

The biodiversity of the mycobiome, an important component of the oral microbial community, and the roles of fungal-bacterial and fungal-immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized. In this study, we sequenced the salivary mycobiome and bacteriome associated with OLP. First, we described the dysbiosis of the microbiome in OLP patients, which exhibits lower levels of fungi and higher levels of bacteria. Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls. Aspergillus was identified as an "OLP-associated" fungus because of its detection at a higher frequency than in the healthy controls. Second, the co-occurrence patterns of the salivary mycobiome-bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls, which diminished in the reticular OLP group and even became positive in the erosive OLP group. Moreover, the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal-Firmicutes and increased fungal-Bacteroidetes sub-networks. Third, several keystone fungal genera (Bovista, Erysiphe, Psathyrella, etc.) demonstrated significant correlations with clinical scores and IL-17 levels. Thus, we established that fungal dysbiosis is associated with the aggravation of OLP. Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity, which participates in OLP pathogenesis.

Objective To summarize the surgical experience gained from robotic mitral valve replacement (MVR), and demonstrate the long-term clinical follow-up results. Methods From Jan. 2007 to Jan. 2015, more than 700 patients underwent various types of robotic cardiac surgery in the Department the authors served in, and of them 43 patients underwent robotic MVR with da Vinci Surgical System (Intuitive Surgical, USA). Among the 43 patients, the average age was 47±11 years (ranged 19-65 years), and sex ratio (female to male) was 0.8:1. Six patients were with heart function of NYHA class Ⅰ, 30 patients were of NYHA class Ⅱ and 7 patients were of NYHA class Ⅲ. The left ventricular ejection fraction (LVEF) were 54%-78% (64.0%±7.1%), and 20 patients had atrial fibrillation on admission, and 35 patients were with rheumatic mitral stenosis (MS). Atrial septal defect (0.7cm in size) co-existed in 1 case and 1 patient had mild aortic regurgitation. Mechanical or bioprosthetic mitral valve was replaced via left atriotomy by using da Vinci robotic surgical system after cardiopulmonary bypass (CPB) set-up. Radiopaque titan clips was employed by Cor-Knot knot-tying device (LSI Solutions, Inc, Victor, NY) to anchor the prosthetic valve. Trans-esophageal echocardiography (TEE) was performed before and after surgery. The operative data were collected and patients were followed up at outpatient clinic regularly up to 6 years. Results All cases were performed successfully with the same surgery. No conversion to median sternotomy or operative mortality occurred. The average operation time was 292±62 minutes (ranged 140-450 minutes) with CPB time of 124±26 minutes and aortic occlusion time of 88±21 minutes. The postoperative mechanical ventilation support time was continued for 15±6 hours, and the average staying length in critical care unit was 4±1 days. No myocardial infarction, ventricular tachycardia or excessive bleeding was complicated. All patients were successfully followed up for a median of 3.5 years (ranged 1 month to 6 years). In the follow-up period, no incidence of death, stroke, re-operation due to prosthetic endocarditis or prosthetic failure was reported. However, 39.5% (n=17) patients still had atrial fibrillation after surgery. Conclusion Robotic MVR is a safe and effective procedure with excellent long term surgical outcome.

Objective: To investigate the clinicopathologic characteristics of intractable epilepsy. Methods: Based on the classification criteria proposed by the International League Against Epilepsy (ILAE), a retrospective analysis of the pathological characteristics was done in 822 patients who underwent epilepsy surgery in Sanbo Brain Hospital, Capital Medical University, from June 2008 to December 2012. Results: The mean age of epilepsy onset was 9.9 years, mean duration of epilepsy was 11.9 years. Complex partial seizures were the main presenting features. Histopathological study showed 33 cases (4.01%) with mild forms of cortical malformations, 690 cases (83.94%) with focal cortical dysplasia (FCD) and 99 cases with others (including 39 pure hippocampal sclerosis, 20 cystosclerosis, 19 Sturge-Weber syndrome, 8 tuberous sclerosis complex, 6 without significant pathological changes, 5 gyral malformations and 2 hamartoma). Among the 690 FCD cases, 106 were FCD typeⅠ, 91 were FCD typeⅡ and 493 were FCDⅢ(Ⅲa: 160, Ⅲb: 106, Ⅲc: 26 and Ⅲd: 201). Conclusions FCDⅢd is the most common histopathological subtype causing intractable epilepsy, mainly due to focal hypoxia/ischemia in the perinatal period, which results in scarring of local brain tissue; this is followed by other isolated forms of FCD (FCDⅠand FCDⅡ), and then FCD Ⅲa and FCD Ⅲb. The reason to distinguish isolated forms of FCD (types Ⅰ and Ⅱ) from FCD Ⅲ and to subclassify FCD Ⅲ is to allow better definition of cortical dyslamination. Therefore, the pathogenic factors of intractable epilepsy can be grouped in greater details, and facilitate the diagnosis and potential curative treatment of intractable epilepsy.

The impact factors were explored to determine the horizontal positional relationship between the umbilicus and the 2nd lumbar spinal process in adults and to verify the accuracy of the localization of Shenshu (BL 23) via the umbilicus. The position of the umbilicus and the 2nd lumbar spinal process was measured in 100 participants and the data were analyzed through SPSS 20.0 software. It was found that the umbilicus and the 2nd lumbar process were not positioned horizontally. The positional relationship of these two sites was not apparently correlated with gender, age, body weight, body height, BMI, waistline and discomfort of lumbar region. The umbilicus was commonly and posteriorly projected on the site between the 4th and 5th lumbar vertebra. It is explained that the localization of Shenshu (BL23) via the umbilicus is not accurate.

Chaetominine is a quinazoline alkaloid originating from the endophytic fungus Aspergillus fumigatus CY018. In this study, we showed evidence that chaetominine has cytotoxic and apoptotic effects on human leukemia K562 cells and investigated the pathway involved in chaetominine-induced apoptosis in detail. Chaetominine inhibited K562 cell growth, with an IC50 value of 35 nM, but showed little inhibitory effect on the growth of human peripheral blood mononuclear cells. The high apoptosis rates, morphological apoptotic features, and DNA fragmentation caused by chaetominine indicated that the cytotoxicity was partially caused by its pro-apoptotic effect. Under chaetominine treatment, the Bax/Bcl-2 ratio was upregulated (from 0.3 to 8), which was followed by a decrease in mitochondrial membrane potential, release of cytochrome c from mitochondria into the cytosol, and stimulation of Apaf-1. Furthermore, activation of caspase-9 and caspase-3, which are the main executers of the apoptotic process, was observed. These results demonstrated that chaetominine induced cell apoptosis via the mitochondrial pathway. Chaetominine inhibited K562 cell growth and induced apoptotic cell death through the intrinsic pathway, which suggests that chaetominine might be a promising therapeutic for leukemia.
