ABSTRACT

Objective:To summarize the thinking and compatibility law of TCM in the treatment of stable angina pectoris (SAP) based on syndrome differentiation using data mining technology.Methods:The clinical studies of TCM treatment for SAP in databases of CNKI, Wanfang Data, VIP and SinoMed China Biomedical Literature Service System were retrieved from the establishment of the databases to February 28, 2022. The frequency statistic, clustering analysis and association rule analysis of TCM data were conducted using Clementine 12.0, Excel 2016, SPSS Statistics 22.0 software, and core prescriptions were summarized.Results:Totally 289 prescriptions were included, involving 185 kinds of Chinese materia medica, including 38 TCM syndrome types. Based on the overall study of SAP "disease", the clinical treatment of SAP was mainly based on the drugs for activating blood circulation and removing blood stasis, tonifying deficiency and strengthening healthy qi, and regulating qi and resolving phlegm. The single Chinese materia medica with high frequency of use were Chuanxiaong Rhizoma, Salviea Miltiorrhizae Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Angelicae Sinensis Radix, etc. The commonly used drug pairs included Chuanxiaong Rhizoma-Angelicae Sinensis Radix, Chuanxiaong Rhizoma-Carthami Flos, Chuanxiaong Rhizoma-Aurantii Fructus Immaturus, etc. The drug complex network diagram and clustering analysis showed that the prescription of Buyang Huanwu Decoction was the basic prescription for the treatment of SAP; based on the specific research of SAP "syndrome", the most common TCM syndromes of SAP were qi deficiency and blood stasis, phlegm and blood stasis, and qi stagnation and blood stasis. The drug properties of the three drugs were mainly warm and mild; the tastes were mainly sweet, pungent and bitter, and most of them belong to the liver, spleen, lung and heart meridian; in terms of specific medication, the basic prescription of qi deficiency and blood stasis syndrome was Buyang Huanwu Decoction, which was composed of high-frequency drugs such as Angelicae Sinensis Radix, Chuanxiaong Rhizoma, Salviea Miltiorrhizae Radix et Rhizoma, etc; The phlegm and blood stasis syndrome was often based on the Gualou Xiebai Banxia Decoction and Taohong Siwu Decoction, which were composed of high frequency drugs such as Pinelliae Rhizoma, Chuanxiaong Rhizoma, Allii Macrostemonis Bulbus, etc; the basic prescription of qi stagnation and blood stasis syndrome was Xuefu Zhuyu Decoction, which was composed of high frequency drugs such as Chuanxiaong Rhizoma, Angelicae Sinensis Radix, Aurantii Fructus. Drug clustering analysis showed that both qi deficiency and blood stasis syndrome and qi stagnation and blood stasis syndrome were divided into 3 categories, and phlegm and blood stasis syndrome were divided into 4 categories.Conclusions:Deficiency, blood stasis, phlegm and stagnation are important pathological factors of SAP, in which qi deficiency is the basis of SAP, blood stasis runs through the disease, or both phlegm and qi stagnation. Focusing on the pathogenesis of deficiency in root and excess in superficiality, drugs with the efficacy of tonifying the deficiency and promoting blood circulation and removing blood stasis are used in clinical treatment, according to different syndrome differentiation of prescription selection.

ABSTRACT

【Objective】 To comprehensively explore the serological characteristics of anti-PP1Pk and potential therapeutic strategies for recurrent miscarriage in p-blood type pregnant women. 【Methods】 Neutralization with pigeon egg white and human plasma, disruption of IgM antibodies by 2-mercaptoethanol reagent, and complement adding were conducted. Anti-PP1Pk titers under different processing conditions, media and temperatures were determined, and neutralizing effect of human plasma on anti-PP1Pk and its sensitization complement ability were analyzed. 【Results】 The titers of anti-PP1Pk in saline and column agglutination were 4 and 8, respectively. Low temperature increased titers, while β-mercaptoethanol treatment significantly reduced them. Pigeon egg white partially neutralized anti-PP1Pk antibodies. Human plasma was also capable of reducing anti-PP1Pk titers with neutralization capability surpassing that of pigeon egg white, and there were individual differences in neutralization capability. 【Conclusion】 The anti-PP1Pk was a blend of antibodies encompassing both IgM and IgG types, exhibiting cold reactivity, and having the potential for complement activation. Human plasma emerges as an effective modulator for diminishing the efficacy of anti-PP1Pk. Plasma transfusion holds promise as a therapeutic avenue for addressing recurrent miscarriages in pregnant individuals with the p phenotype.

ABSTRACT

Objective:To investigate the correlation between serum albumin and hypoalbuminemia (HA) and the outcome after endovascular mechanical thrombectomy (EMT) in patients with stroke caused by acute anterior circulation large vessel occlusion.Methods:Stroke patients caused by acute anterior circulation large vessel occlusion received EMT treatment at the Department of Emergency Stroke, the Affiliated Hospital of Jining Medical University from June 2020 to August 2022 were retrospectively included. The demographic information, baseline clinical data, endovascular treatment parameters, and clinical outcomes of the patients were collected. HA was defined as serum albumin <35 g/L within 24 h of admission, and poor outcome was defined as the modified Rankin Scale score >2 at 90 d after onset. Multivariate logistic regression analysis was used to identify the independent influencing factors for poor outcomes. Results:A total of 177 patients were included, with a median age of 66 years, and 126 (71.19%) were males. Thirty-nine patients (22.03%) had HA, and 119 (67.23%) had poor outcomes. The proportion of pulmonary infection in the HA group was significantly higher than that in the non-HA group ( P<0.05). Multivariate logistic regression analysis showed that lower serum albumin (odds ratio [ OR] 4.102, 95% confidence interval [ CI] 1.316-16.451; P=0.028), postprocedural neurological deterioration ( OR 6.326, 95% CI 1.263-48.318; P=0.042) and pulmonary infection ( OR 5.873, 95% CI 1.028-24.452; P=0.018) were significantly independently associated with the poor outcomes. Conclusions:The HA group has a higher incidence of postprocedural pulmonary infection. Lower serum albumin, postprocedural neurological deterioration and pulmonary infection are the independent risk factors for the poor outcomes in patients with anterior circulation ischemic stroke who had successful recanalization after EMT.

ABSTRACT

Infertility is gradually becoming a major problem affecting health worldwide, and male factors also play an important role in infertility. Extracellular vesicles (EVs) are ultramicro membranous vesicles released by cells during activation or apoptosis, which play an important role in cell communication. Relevant studies have shown that extracellular vesicles contain a variety of bioactive substances and participate in infertility related pathophysiological processes by influencing the content of intercellular transmission. Therefore, we reviewed the relationship between extracellular vesicles and male infertility, and expounded the occurrence and potential treatment of male infertility from another perspective.

ABSTRACT

The prevention and control of hospital infections(hereinafter referred to as infection control) is key to the implementation of " medical and prevention integration" in medical institutions. And the professional knowledge and skill level of infection control professionals is one of the critical factors directly affecting the infection control capacity of these institutions. Jiangsu Province has been exploring to establish a job training system for newly recruited full-time infection control staff since 2021 based on their core competency needs. In January 2022, the new training system was put into use. The province formulated a training outline for new full-time infection control personnel, established a provincial-level infection control trainers pool through training and competitive selection, and then selected the best ones for provincial infection control full-time personnel training bases. Then the province organized job training covering both theoretical learning and practical aspects, and examined their corresponding theoretical knowledge and practical operation. Theoretical learning was made via online courses; Practical training was made at designated tertiary hospitals, covering clinical practice in key departments, environmental hygiene monitoring, hospital infection case monitoring, and application of infection control information systems. Among 804 new full-time personnel trained in 2022, 567 passed the graduation examination at a pass rate of 70.52%. The job training system for new full-time infection control personnel built in Jiangsu Province proves useful for the management of job training for such personnel in other provinces.

ABSTRACT

Objective:To systematically review the teaching effect of problem-based learning (PBL) combined with evidence-based medicine (EBM) teaching mode on the standardized residency training.Methods:CNKI, Wanfang database, VIP database, SinoMed, Embase, PubMed and Web of SCI databases were searched, and the randomized controlled trial (RCT) studies of the application of EBM combined with PBL teaching in standardized residency training were collected. The retrieval time was from the establishment to 1st July, 2018. Two investigators independently extracted data and assessed the quality of the studies. After assessing the risk of bias of included studies, Meta-analysis was performed on RevMan 5.3.Results:In total, 4 studies were included in the review. Narrative assessment was adopted, because outcome indicators of these study were varied and the quality of the literatures could not meet the requirement of Meta-analysis. Our study suggested that the residents who were in PBL combined with EBM teaching mode group got higher scores in the standardized residency training, compared with those in the lecture-based learning (LBL) teaching mode group, especially in case analysis score, total score of examination, improvement of clinical thinking ability, communication and expression ability, organization and cooperation ability, etc.Conclusion:The current evidence suggests that the application of EBM combined with PBL teaching mode has a positive effect on the standardized residency training. Compared with the traditional LBL teaching, EBM can improve students' ability. However, limited by the quantity and quality of included studies, the above conclusions still need to be verified by more studies with larger samples and higher quality.

ABSTRACT

Objective:To explore the risk factors associated with a three-month prognosis in patients with aortic acute cerebral infarction.Methods:A prospective study was conducted on 191 patients with aorthropathic acute cerebral infarction included in the Department of Neurology from June 2018 to December 2019, and the patients were divided into good prognosis group (153 cases) and poor prognosis group (38 cases) according to the MRS score of the patient's 3-month prognosis, and the general data, past medical history and blood pressure variability evaluation index (BPV) between the two groups were correlated analysis. The t-test was used to compare the measurement data with normal distribution, the χ 2 test was used to compare the counting data, and the Logistic regression analysis was used to analyze the risk factors. Results:The proportion of patients with diabetes history in the poor prognosis group (20.3% (31/153)), admission NIHSS score ((3.03±2.01) points), standard deviation (SD) ((12.06±4.46) mmHg) and coefficient of variation (CV) ((8.61±3.08)%) of systolic blood pressure at 24 h were lower than those in the good prognosis group (47.4% (18/38), (5.61±3.84) points, (14.75±3.46) mmHg, (10.41±2.18)%), the differences were statistically significant (the statistical values were χ 2=11.73, t=4.01, t=3.46, t=3.38; P values were 0.001, <0.001, 0.001, and 0.001, respectively). Because 24 h systolic blood pressure SD and 24 h systolic blood pressure CV had obvious collinearity, they were respectively included in the Logistic regression model. Taking diabetes history, NIHSS score and 24 h systolic blood pressure SD into the variables, the multivariate Logistic regression results of adverse prognostic risk factors in patients with acute cerebral infarction showed that the history of diabetes mellitus ( OR=3.649, 95% CI: 1.545-8.648, P=0.003), NIHSS score ( OR=1.472, 95% CI: 1.247-1.725, P<0.001) and 24 h systolic blood pressure SD ( OR=1.201, 95% CI: 1.085-1.336, P<0.001). Taking diabetes history, NIHSS score and 24 h systolic blood pressure CV into consideration, multivariate Logistic regression results of adverse prognostic risk factors in patients with acute cerebral infarction showed that the history of diabetes mellitus ( OR=4.695, 95% CI: 1.873-11.766, P=0.001), admission NIHSS score ( OR=1.922, 95% CI: 1.513-2.441, P<0.001) and 24 h systolic blood pressure CV ( OR=1.220, 95% CI: 1.045-1.425, P=0.012). All are independent risk factors influencing the prognosis of patients. Conclusion:The effect of 24 h systolic blood pressure SD and 24 h systolic blood pressure CV on patient prognosis was more valuable in clinical prediction, and the prognosis value of controlling blood glucose levels in patients with diabetes was higher in patients with cerebral infarction.

ABSTRACT

ObjectiveTo explore the influence of Xiaoai Jiedu prescription (XJP)-containing serum on natural killer (NK) cells′ lethal effect on colon cancer cells and the molecular mechanism. MethodXJP-containing serum (0.1%, 0.5%, 1%, 5%, 10%) was used to treat HCT-116 cells and NK-92MI cells respectively for 24 h, and methyl thiazolyl tetrazolium (MTT) assay was employed to detect cell proliferation. Then, low-concentration (0.1%, 0.5%, 1%) XJP-containing serum was selected to treat co-cultured HCT-116 cells and NK-92MI cells for 24 h and calcein acetoxymethyl ester/propidium iodide (Calcein-AM/PI) was applied to detect the killing effect of NK cells on colon cancer cells. Flow cytometry was used to detect apoptosis of colon cancer cells, Western blot the expression of apoptosis-related proteins and signal transducer and activator of transcription 4 (STAT4) pathway-related proteins, and enzyme-linked immunosorbent assay (ELISA) the secretion of interferon (IFN)-γ. ResultHigh-concentration (5%, 10%) XJP-containing serum inhibited the proliferation of HCT-116 and NK-92MI cells (P<0.01), while low-concentration (0.1%, 0.5%, 1%) XJP-containing serum had no obvious influence on cell proliferation compared with the blank group. As compared with the blank group, low-concentration XJP-containing serum enhanced the killing activity of NK cells against colon cancer cells in a concentration-dependent manner (P<0.01), and induced apoptosis of colon cancer cells (P<0.01). Moreover, XJP-containing serum (0.1%, 0.5%, 1%) down-regulated the expression of B-cell lymphoma 2 (Bcl-2) and B-cell lymphoma-extra large (Bcl-xl), and up-regulated the expression of Bcl-2-associated X (Bax) compared with the blank group (P<0.05, P<0.01). Compared with the co-culture group, XJP-containing serum (0.1%, 0.5%, 1%) increased the expression of p-STAT4 and IFN-γ (P<0.05). ELISA result showed that XJP-containing serum (0.1%, 0.5%, 1%) raised IFN-γ secretion (P<0.01). ConclusionXJP-containing serum can enhance the activity of NK cells to kill colon cancer cells. The mechanism is the likelihood that it activates STAT4 pathway, increases IFN-γ secretion by NK cells, down-regulates the expression of Bcl-xl and Bcl-2, and up-regulates the expression of Bax, thereby promoting the apoptosis of colon cancer cells.

ABSTRACT

Objective:To observe the morphological characteristics of retinal vessels in patients with ischemic stroke, and to preliminary analyze the correlation between retinal vascular morphological parameters and ischemic stroke.Methods:A retrospective study. From May 2015 to May 2017, 73 patients with ischemic stroke (ischemic stroke group) confirmed by examination at the Beijing Friendship Hospital, Capital Medical University were included in this study. In addition, 146 patients were included in the control group. A total of 146 patients with acute stroke who were excluded by head CT and/or magnetic resonance imaging were selected as the control group. Fundus images of patients were collected by nonmydriatic fundus camera. Retinal vascular parameters were measured by artificial intelligence fundus image analysis system, included retinal artery and vein caliber as well as vascular curvature, branching angle, fractal dimension, and density. The morphological characteristics of retinal vessels were compared between the control and ischemic stroke groups, and correlation between the retinal vascular parameters and ischemic stroke was analyzed using binary logistic regression.Results:Compared with the control group, the ischemic stroke group had thinner retinal artery caliber, smaller retinal vascular fractal dimension, and lower retinal vascular density; moreover, these differences were statistically significant ( t=3.232, 3.502, 3.280; P<0.05). Vascular fractal dimension [odds ratio ( OR)=0.291, 95% confidence interval ( CI) 0.160-0.528] and retinal artery caliber ( OR=0.924, 95% CI 0.870-0.981) were strongly correlated with ischemic stroke ( P<0.01). Conclusion:Compared with the control group, the retinal artery caliber, fractal dimension and retinal vascular density in ischemic stroke group are smaller; decreased retinal artery caliber and fractal dimension are correlated with ischemic stroke.

Objective To understand the status of infection with multidrug-resistant organisms (MDROs) in intensive care units(ICUs),and evaluate the intervention efficacy of targeted monitoring.Methods Prospective study was adopted,patients who were admitted to ICUs in 2014-2015 were selected (January-December 2014 was as preintervention stage,January-December 2015 was as intervention stage),trend of MDRO infection before and after intervention were compared and analyzed.Results Before and after intervention,297 and 217 strains of MDROs were isolated respectively,except carbapenem-resistant Pseudomonasaeruginosa (CRPA),the isolated strains of carbapenem-resistant Acinetobacterbaunannii (CRAB),carbapenem-resistant Enterobacteriaceae (CRE),methicillin-resistant Staphylococcus aureus(MRSA),and vancomycin-resistant Enterococcus (VRE) declined after intervention.MDRO infection rate declined from 7.17 % before intervention to 3.88% after intervention,infection rate of CRAB and CRE after intervention were both lower than before intervention (both P<0.05);MDRO infection rates in general ICU and internal medicine ICU increased from 8.75% and 7.84‰ before intervention to 4.39‰ and 2.28% after intervention,respectively (both P<0.05).After taking comprehensive intervention measures,compliance to prevention and control measures,such as ordering rate of doctor's advice on contact isolation for 24 hours,hand hygiene,health care workers' awareness all enhanced significantly(all P<0.05).Conclusion Targeted monitoring and intervention measures can reduce isolation rate of MDROs in ICUs.
